    As one of the environmental problems in sea areas surrounding a very large floating structure (VLFS), change in flow condition is important, and it is one of the factors dominating the prediction of succeeding diffusion and ecosystems. Although a multi-layer model is in wide use for computation of flow condition and diffusion in one inner bay, its applicability should be reexamined because of no consideration of VLFSs. In this study, flow velocity profiles around a barge were then measured through the towing test of a barge in shallow water, and compared with computation results using a multi-layer model. The multi-layer model computed the flow velocity profiles by dividing the flow region to be computed into normal one and that under VLFS, and determined pressures under VLFS by 2-D Poisson`s equation. Slip condition was used as boundary condition at the bottom considering the number of layers under VLFS. Further numerical computation was conducted by 2-D MAC method, in particular, to compare flow around the wake of VLFS with experimental one. Both computation results well agreed with experimental one. 3 refs., 9 figs., 1 tab.

    The Kibushi clay and the Gairome clay which have been taking the role as the domestic produced bonding materials for refractories are running out. This paper reports their current situation and measures from the standpoint of producers. The Kibushi clay production has been decreasing since it has peaked in 1975 at 855,000 tons down to as low as its half at 400,000 tons in 1989. The Gairome clay production has also been decreased sharply from having been produced at 30 mines to 7 mines in Gifu Prefecture. The current situation is such that not only higher cost is incurred in removing gravel beds covering the clay bed, but also no gravel disposal areas can be procured, and no profitability can be assumed because of degradation in clay quality. On the other hand, demand as raw material for sanitary earthenwares and potteries has been increasing rapidly from 2,265,000 tons to 2,779,000 tons, hence import dependence of the material is rising. Positive activities as measures against the ore depletion include an establishment of a company jointly invested by five companies in 1991, which intends to develop the industry from a mining industry to a manufacturing industry by custom-blending and reforming various kinds of clays produced in different locations, including imports, to achieve stable supply. 1 tab.

    'Geoscientific research' at Tono is developing site investigation, characterization and assessment techniques for understanding of geological environment. Their important themes are to establish a methodology for analyzing uncertainties in heterogeneous geological environment and to develop investigation techniques for reducing the uncertainties efficiently. The current study proposes a new approach where all the possible options in the models and data-sets that cannot be excluded in the light of the evidence available is identified. This approach enables uncertainties associated with the understanding at a given stage of the site characterization to be made explicitly using an uncertainty analysis technique based on Fuzzy geostatistics. This in turn, supports the design of the following investigation stage to reduce the uncertainties efficiently. In this report the technique has been tested through geological modelling and groundwater analyses with Tono area case based on current knowledge, to demonstrate its applicability. This report summarizes as follows; 1) It is possible to quantify the uncertainties with Tono area case based on current knowledge using the technique. 2) Based on sensitivity analyses, it is possible to support designs of the following investigation stage to reduce the uncertainties efficiently. 3) The methodology of the technique has been developed with Tono area case. 4) The above could evaluate its applicability and propose further issues for synthesis of the methodology.

    The uranium deposits of the Tono mine, Gifu Prefecture, Japan, occur in the basal part of the Toki group of Miocene age, and are distributed in the tributaries or at the head of channels on the plane of unconformity under the formation. These features characterize the basal ground-water type of uranium deposit, and they are unique in that their typical ore mineral is a zeolite of the heulandite-clinoptilolite group, uranium being adsorbed in it. The paper presents the history of formation of the Tsukiyoshi deposits, the most intensely explored in the Tono mine. The matrices of conglomerates and sandstones of the Toki group usually contain tuffaceous material, which has been montmorillonitized or zeolitized diagenetically. The conduit of uranium-bearing ground waters that migrated from the basement granites into the Tertiary sediments was controlled by the impermeable barriers, which are rocks in which montmorillonite predominated, or by the Tsukiyoshi fault, as well as by channel structures. Where the waters became rather stagnant, uranium was adsorbed in zeolite from them. Enrichment of uranium further proceeded locally as follows. Pyrite was oxidized to produce sulphuric acid solution which leached the uranium that had been adsorbed in zeolite. The pH of the uranium-rich solution became higher and higher in the course of migration and, as soon as it reached about 4, the uranium in the solution was again adsorbed in zeolite, the uranium content of which may have been enriched up to 0.9%. Coffinites have been formed where uranium was accumulated over the adsorption capacity of zeolite or where strongly reducing conditions were maintained by carbonaceous matter. (author)

    Tono Geoscience Center, Japan Nuclear Cycle Development Institute has been conducting a wide range of geoscientific research in order to build firm scientific and technological basis for the research and development of geological disposal. One of the geoscientific research programme is a Regional Hydrogeological Study (RHS) project in the Tono region, central Japan. This report mainly summarizes the results of research in DH-14 and DH-15 boreholes at Toki city and Mizunami city in fiscal year 2004 which were carried out to support and improve the results in fiscal year 2003. The research in the regional scale area shows the reliability of conceptual hydrogeological model and numerical simulation for the evaluation of regional hydrogeology. On the other hand, the geological and geophysical investigation, and borehole investigation during the surface-based investigations in the local scale area provide the pragmatic distribution of hydrogeological structure that may control regional groundwater hydrology. Hydrogeological simulations regarding the geological structure such as fault and hydrogeological property demonstrate the priority of investigation of geological structure for the evaluation of hydrogeology. The fault perpendicular to groundwater flow direction crucially affects on regional hydrology. Such fault is necessary to be investigated by priority. Hydrochemical investigation shows that chemical evolution process in this groundwater illustrated is mixing between groundwaters with different salinities. Principal component analysis and mass balance calculation reveal reliable chemistry of end-member waters for mixing. Regarding methodology development, the strategy and procedure of investigations are summarized based on the results of surface-based investigation. Moreover the multi interval monitoring system for water pressure and temperature has developed and started to monitor the in-situ condition of groundwater.

    The purposes of this research are to establish large-scale reforestation techniques, and to transfer these techniques into Indonesia for contributing to the preservation of tropical rain forests and the protection of global warming. Lauan trees provide disease and drying resistance properties by inoculating their roots with mycorrhizal fungi, to promote their growth. This is due to the symbiotic relationship between them, in which mycelia of mycorrhizal fungi collect and bring water and nutritive substances in the soil to the roots of lauan trees and intake sugars from the roots as nutrition. Since lauan trees are local variety, they are suitable for the preservation of biosystem. Since their growth life is long, they are suitable for the fixation of CO2. However, the reforestation techniques have not yet been established. Between FY 1992 and 1997, a high survival rate about 60% was obtained through a method in which natural seedlings in mountains were implanted and a method in which seeds were planted in the nursery. About 34000 lauan trees have been planted for the reforestation tests. An inoculation method was established for the accelerated growth of seedlings with mycorrhizal fungi. Through the inoculation, the growth rate was increased up to three times of that without inoculation. The lauan trees grew up to 5 m, and the survival rate was also increased up to twice. 11 figs., 3 tabs.

    The Tono Geoscience Center (TGC) of JAEA has been conducting research into deep underground environments for R and D program related to the geological disposal of High-Level Radioactive Waste. The AMS system of the TGC has routinely been used for 14 C-AMS since it started to be operated in 1998. In recent years, we have promoted the development of system technology for routine 10 Be-AMS. An inter-laboratory comparison of the 14 C-AMS was performed with the JAEA-AMS-MUTSU. The data of isotope ratios obtained with both AMS systems showed that there is no significant difference between them. In the development for the 10 Be-AMS, several test measurements have been performed by using standard samples. The results indicated fairly robust stability of data quality, which contributed to complete the development for routine 10 Be measurement. We are now in the stage of the development for routine 26 Al-AMS. (author)

    'Geoscientific research' at the Tono Area is developing site investigation, characterization and assessment techniques for understanding of geological environment. Their important goals are to establish a methodology for analyzing uncertainties in heterogeneous geological environment and to develop investigation technique for efficiently reducing the uncertainties. The current study proposes a new approach where all the possible options in the models and data-sets, which cannot be excluded in the light of the evidences available, are identified. This approach enables uncertainties associated with the understanding at a given stage of the site characterization to be made explicitly using an uncertainty analysis technique based on Fuzzy geostatics. This approach supports the design of the following investigation stage and reduces the uncertainties efficiently. In FY H16 the technique has been tested through geological modelling and groundwater analyses with Tono Area case based on current knowledge, to demonstrate its applicability and to compile the knowledge/information required to describe the H17 report. This report can be summarized as follows: 1) The knowledge/information required to describe the heterogeneous characteristics was compiled and connected to uncertainties associated with the characterization of a geological environment using a synthesis diagram. 2) Methodologies for assignment and screening of parameters were developed by using Evidential Support Logic (ESL). 3) Applicability of the technique could be confirmed with Tono Area case. 4) This report proposed a new methodology that integrates the technique into JAEA ordinary technique to good advantage in the geoscientific research project.

    Geochemical investigations form an important part of the R and D program at the Tono study site, central Japan. Detailed geological structure and groundwater chemistry have been studied to understand the geochemical environment in the sedimentary and crystalline rocks distributed in this area. The chemical evolution of the groundwater in the sedimentary rocks is characterized with the variation in Na + , Ca 2+ and HCO 3 - concentrations, and ion exchange and dissolution of calcite are dominant reactions in the evolution of groundwater. Geological investigation shows that a fracture system of crystalline rock can be classified into:intact zone, moderately fractured zone and intensely fractured zone, according to the frequency and the width of fractures and fractured zones. The groundwater in the intact and fractured zones of crystalline rock are characterized by Na + -Ca 2+ -HCO 3 - or Na + -HCO 3 - dominated water, and Na + -Ca 2+ -Fe 2+ -HCO 3 - dominated water. The chemical evolution of groundwater is, generally, controlled by water-rock interaction between plagioclase, iron minerals and groundwater. The groundwater at depth of G.L.-186m in the crystalline rock at the Tono area is characterized by the mixture between the oxidized surface water and the reduced groundwater. The investigation based on correlation between geological structures and groundwater chemistry can be applied to understand the geochemical environment in deep crystalline rock, and will support the development of a realistic hydrogeochemical model.

    Goldmann applanation tonometry and dynamic contour tonometry (PASCAL) are two well established slit lamp mounted tonometric methods. Intraocular pressure measurement in bedridden patients and children is often only possible using hand held tonometers (TonoPenXL, Perkins tonometer, Draeger tonometer). This study was performed to evaluate the hand held ICare tonometer, which is based on the rebound method. A total of 102 eyes were examined by two highly experienced ophthalmologists for: 1) ophthalmological status, 2) central corneal power (Zeiss IOL-Master), 3) central corneal thickness (Tomey ultrasound pachymetry, five successive measurements, SDr=0.592-0.642; p<0.001). There was a great intra-individual variability of up to 17 mmHg between the GAT, TonoPenXL and ICare methods. The ICare tonometer is easy to handle and high reliability. The data are comparable with those from the Goldmann tonometer. A tonography effect of 0.6 mmHg in the successive measurement series was found.

    The JAEA-AMS-TONO (Japan Atomic Energy Agency's Accelerator Mass Spectrometer established at the Tono Geoscience Center) facility has been used for the dating of geological samples. The AMS system is versatile, based on a 5 MV tandem Pelletron-type accelerator. Since its establishment in 1997, the AMS system has been used for measurement of carbon-14 (14C) mainly for 14C dating studies in neotectonics and hydrogeology, in support of JAEA's research on geosphere stability applicable to the long-term isolation of high-level radioactive waste. Results of the measurement of 14C in soils and plants has been applied to the dating of fault activity and volcanism. Development of beryllium-10 (10Be) and aluminum-26 (26Al) AMS systems are now underway to enhance the capability of the multi-nuclide AMS in studies of dating by cosmogenic nuclides. The 10Be-AMS system has already been used for routine measurements in applied studies and improvements of the measurement technique have been made. Now we plan to fine tune the system and perform test measurements to develop the 26Al-AMS system.

    1996-01-01

    Natural analogue regarding long-term performance of the geological disposal system for radioactive waste isolation is essentially the study of geochemical process which has been evolved in geological environment. All geochemical studies, however, will not be nominated as natural analogue studies. It is, therefore, important to be clear the criteria for natural analogue study with the view of analogy by following three categories, (1) Conceptual model development, (2) Data provision and (3) Model testing, for the concept of geological disposal and safety assessment model. Rethinking of the criteria for natural analogue study through the case of Tono Natural Analogue Study, and the usefulness of natural analogue study for the safety assessment of geological disposal system in Japan have been presented in this paper.

    Numerical models are powerful tools for the characterization of groundwater flow, especially when integrating geochemical and hydrogeological data. This paper describes modeling exercises performed in the area surrounding the Mizunami Underground Research Laboratory (MIU) Construction Site in central Japan. A particular issue being investigated at the MIU Site is the presence of saline water detected at depth in certain boreholes. The main objective of this study is to develop conceptual physical models for the origin of this salinity and to test these conceptual models using numerical modeling techniques. One scenario being investigated is that the saline fluids represent residual Miocene age seawater which has been slightly altered by water-rock interactions. It is likely that during Miocene times, seawater inundated the Tono area. This hypothesis is partially supported by carbon and oxygen isotopic data of the calcite fracture filling materials.

    Measurements were carried out on three buildings having different heat insulation, airtightness and heat capacity for testing the hot heast enviroments (having a room size of about 4.6 m{times}3.7m{times}2.3 m) as to the temperature differences between the upper and lower parts of the room and the MRT (mean radiation temperature, representing the temperature of radiation from the wall face). These are compared according to types of heating appliance. The result is summarize as follows: The temperature difference in the upper and lower parts is affected largely by the airtightness of the building, the difference being capable of getting reduced by rasing the airtightness even in a buildings low in heat insulation. In a building with low airtightness, type of heating appliance and its installation location affect the temperature difference. The MRT is determined determined nearly completely by the heat insulation of the wall face in a room, but it tends to be affected easily by the specification and area of windows. A floor heating system increases the MRT and generates very little difference in temperatures in the upper and lower parts of the room. A comparison using a PMV (one of the indexes for enviromental comfort in a room) was also conducted. 12 figs., 7tabs.

    In order to verify the safety assessment for geological disposal system of high-level radioactive waste, it is necessary to evaluate properly the stability of the disposal system under natural hydrogeological environment over long period of time (ten to hundred thousands years). For the safety assessment for that in the Japanese Islands, many geological processes inherent in the tectonically active Island-Arc system should be also taken into consideration in addition to those in stable continental environment. However, it is difficult because some processes such as earthquake seem to be accidental and some are periodic or gradual over our life scale. The uranium deposits in Japan are subjected to many geological processes inherent in the tectonically active Island-Arc system. The studies on long-term preservation of uranium deposits in Japan from a natural analogue viewpoint would be expected to provide useful information for the assessment in the Japanese Islands over long period of time. In order to understand the behavior of radionuclides under natural hydrogeological environment in Japanese Islands over long period of time, the uranium deposits in Japan, especially of the Tono uranium deposit was investigated from a natural analogue viewpoint under the course of joint research program by University of Tsukuba and Japan Nuclear Cycle Development Institute. Important conclusions obtained in the present study are summarized as follows: The migration behavior of the radionuclides in the granite area is mainly controlled by the stability of original minerals in oxic condition, being due to poor reducing agents such as organic matter and sulfide minerals. In the case of hydrothermal alteration, yttrialite and fergusonite were decomposed and thorogummite was formed at the altered part, whereas zircon and allanite have not been significantly altered. In the case of weathering, autunite and torbernite were formed, probably due to the high phosphorus weathering

    The Tono Geoscience Center of the Japan Nuclear Cycle Development Institute (JNC) has progressed various types of survey and research targeted at new Tertiary sedimentary rocks and bed rock granite distributing from earth surface to about 500 m in depth at and around the Tono mine belonged to Toki-city of Gifu prefecture, as a part of the stratum science research. The survey and research are carried out to aim at understanding on material transfer and delay feature of uranium in the sedimentary rocks with geological characteristics such as dislocation according to the 'Basic plan on survey and testing research at the Tono mine', and their items are survey and testing researches on 1) dynamic stability of rocks, 2) geological environment around road, 3) material transfer in rocks, and 4) the Tsukiyoshi fault. Results obtained in the survey and testing research not only are reflected as a base of the stratum disposal R and D, but also contribute to academic research on deep underground, application of underground space, and so on. For example, a research on sampling and applying of rocks containing uranium helps elucidation on formation of uranium ore deposit and forming process. (G.K.)

    The relationship between change in resistivity and rainfall was studied by continuously measuring resistivities of fracture zone and stratum boundary along the measuring line of 95m long from the top to bottom of rock slope. The measurement field was located on a hill of 150-200m high at the northern part of Arima-Takatsuki tectonic line. Electrodes of 30m in maximum measuring depth were arranged at 289 points by dipole-dipole method. Resistivity was continuously measured at time intervals of 6 hours. Apparent resistivity was hardly affected by rainfall at points with less infiltration of stormwater from the ground surface, while it decreased by rainfall at points on fracture zone, stratum boundary or bleeding channel. The change rate of apparent resistivity could be approximated with the exponential function of rainfall. In such case, the apparent resistivity under most dried condition at the concerned point should be used as reference maximum apparent resistivity. The change rate of apparent resistivity due to rainfall in fracture zone reflects infiltration of stormwater, suggesting to be useful for disaster prevention of slopes. 5 refs., 6 figs.

    Dose assessment associated with closure activity of the Tono Mine has been performed. In this assessment, exposure dose has been calculated on groundwater and surface water migration of radionuclide from 1) waste rock in the waste rock dump facility, 2) mining waste in the mining waste facility, and 3) uranium ore and waste rock backfilled in the shafts and galleries. Direct and skyshine gamma rays and exposure of exhalated radon from the waste rock dump has also been evaluated. An evaluation tool developed for safety assessment for sub-surface disposal of radioactive waste is utilized for this assessment. Localities for dose evaluation are selected at the Higashihoragawa and Hiyoshigawa based on the topography around the Tono Mine and groundwater flow simulation. Evaluation scenarios are classified into 'Scenario for intake of agricultural product' as the base scenario, and 'Scenario for intake of groundwater' as the alternative scenario. Parameters for dose assessment are set-up based on the existing data. But the range and uncertainty of parameters are taken into account in the 'alternative cases'. As the result of dose assessment, maximum exposure dose of the base scenario is 0.08mSv/year, and 0.09mSv/year including direct and skyshine gamma rays and exposure of exhalatedradon at the Higashihoragawa. Maximum exposure dose of the alternative scenario is 0.08mSv/year (0.09mSv/year including direct and skyshine gamma rays and exposure of exhalated radon). On the alternative cases, exposure doses are calculated as 0.05-0.14mSv/year in both of the base and alternative scenarios. At the Hiyoshigawa, maximum exposure dose is less than 0.001mSv/year (1x10 -6 mSv/year) for the base scenario, and 0.001mSv/year for the alternative scenario. On the alternative cases, maximum exposure doses are less than 0.001mSv/year for all cases of the base scenario and 0.0006-0.002mSv/year for the alternative scenario. (author)

    To evaluate the influence of central corneal thickness (CCT) on intraocular pressure (IOP) measurements made with the Goldmann applanation tonometer (GAT), Tono-Pen XL, ocular blood flow tonograph (OBF), and Canon TX-10 non-contact tonometer (NCT). CCT was recorded for either eye (randomly selected) of each of 105 untreated patients with ocular hypertension and glaucoma attending the glaucoma research unit at Moorfields Eye Hospital. For each of the selected eyes, IOP was measured with the GAT (two observers), Tono-Pen, OBF, and NCT in a randomised order. The relation of measured IOP and of inter-tonometer differences with CCT and subject age was explored by linear regression analysis. A significant association between measured IOP and CCT was found with each instrument. The change in measured IOP for a 10 mum increase in CCT was 0.28, 0.31, 0.38, and 0.46 for the GAT, Tono-Pen, OBF, and NCT, respectively (all p< or = 0.05). There was a significant association between the NCT/GAT differences and CCT, with a tendency of NCT to overestimate GAT in eyes with thicker corneas. There was a significant association between GAT/Tono-Pen and OBF/Tono-Pen differences and age, with a tendency of GAT and OBF to overestimate the Tono-Pen in eyes of older subjects. IOP measurement by all four methods is affected by CCT. The NCT is affected by CCT significantly more than the GAT. Subject age has a differential effect on the IOP measurements made by the GAT and OBF compared to the Tono-Pen.

    1999-12-01

    Hydrochemical investigation of Tertiary sedimentary rocks at JNC's Tono in-situ tests site indicate the groundwaters are: meteoric in origin, chemically reducing at depths greater than a few tens of meters in the sedimentary rock, relatively old [carbon-14 ages of groundwaters collected from the lower part of the sedimentary sequence range from 13,000 to 15,000 years BP (before present)]. Ca-Na-HCO 3 type solutions near the surface, changing to Na-HCO 3 type groundwaters with increasing depth. The chemical evolution of the groundwaters is modeled assuming local equilibrium for selected mineral-fluid reactions, taking into account the rainwater origin of these solutions. Results suggest it is possible to interpret approximately the 'real' groundwater chemistry (i.e., pH, Eh, total dissolved concentrations of Si, Na, Ca, K, Al, carbonate and sulfate) if the following assumptions are adopted: CO 2 concentration in the gas phase contacting pore solutions in the overlying soil zone=10 -1 bar, minerals in the rock zone that control the solubility of respective elements in the groundwater include; chalcedony (Si), albite (Na), kaolinite (Al), calcite (Ca and carbonate), muscovite (K) and pyrite (Eh and sulfate). It is noted, however, that the available field data may not be sufficient to adequately constrain parameters in the groundwater evolution model. In particular, more detailed information characterizing certain site properties (e.g., the actual mineralogy of 'plagioclase', 'clay' and 'zeolite') are needed to improve the model. Alternative conceptual models of key reactions may also be necessary. For this reason, a model that accounts for ion-exchange reactions among clay minerals, and which is based on the results of laboratory experiments, has also been evaluated in the present study. Further improvements of model considering ion-exchange reactions are needed in future, however. (author)

    The purpose of the study was to compare the levels of the intraocular pressure (NOT) measured in one eye at the same moment by three different methods: by Goldmann applanation tonometer (AT), non-contact tonometer (BT) and Tono-Pen (TP). It was further set the average variability of the performed measurements for particular tonometric methods. NOT was assessed in 106 eyes of 106 subjects aged 7-77 years (average 34.3 +/- 17.1 years). NOT was measured at the same moment with BT, TP and AT. The obtained data were statistically analyzed. The average NOT was 16.55 +/- 2.95, 17.95 +/- 4.47 and 16.13 +/- 3.4 mmHg when AT, BT and TP were applied. Average variability of three measurements for AT, BT and TP was 1.51 +/- 0.96, 1.78 +/- 1.08 and 1.47 +/- 0.9 mmHg. Average NOT levels of the measured AT and TP were almost identical with a difference of 0.42 mmHg (p = 0.236). Average level of the intraocular pressure measured by BT was higher by 1.40 mmHg and 1.82 mmHg in comparison with AT and TP (p = 0.00002), respectively. NOT measurement produced almost identical average levels at AT and TP, whereas at BT the levels were much higher. Average variability of the three subsequent NOT measurements was the highest at BT, whereas at AT and TP the average variability was lower and nearly identical.

    'Geoscientific research' performed at the Tono Geoscience Center is developing site investigation, characterization and assessment techniques for understanding of geological environment. Their important themes are to establish a methodology for analyzing uncertainties in heterogeneous geological environment, and to develop investigation techniques for reducing the uncertainties efficiently. This study proposes a new approach where all the possible options in the models and data-sets that cannot be excluded in the light of the evidence available, are identified. This approach enables uncertainties associated with the understanding at a given stage of the site characterization to be made explicitly using an uncertainty analysis technique based on Fuzzy geostatistics. This, in turn, supports the design of the following investigation stage to reduce the uncertainties efficiently. In the study, current knowledge had been compiled, and the technique had been advanced through geological modeling and groundwater analyses in the Tono area. This report systematized the uncertainty analysis methodology associated with the characterization of the geological environment, and organized the procedure of the methodology with the application examples in the study. This report also dealt with investigation techniques for reducing the uncertainties efficiently, and underground facility design options for handling geological uncertainties based on the characterization of the geological environment.

    The groundwater flow analysis involve the groundwater recharge from the subsurface to the rock mass. According to water balance method, annual groundwater recharge is calculated by the remainder of annual evapotranspirator and river flow from annual precipitation. In this estimation, hydrological and meteorological data observed for 5 years on the watershed in Tono mine area is used. Annual precipitation ranges from 1,000 to 1,900 mm and annual river flow ranges from 400 to 1,300 mm, then river flow depends critically on precipitation. Annual evapotranspiration calculated by Penman method ranges from 400 to 500 mm. It is less fluctuant than annual precipitation. As the result of examination of water balance in subsurface zone estimated, annual ground water recharge ranges from 10 to 200 mm in this watershed. (author)

    Full Text Available Water resources are a major source of economic development for most West African (WA countries. There is, however inadequate information on these resources for the purposes of planning, decision-making and management. This paper explores the potential for using a state of the art hydrological model (WRF-Hydro in a fully coupled (i.e. land surface hydrology-atmosphere mode to assess these water resources, particularly the Tono basin in Ghana. The WRF-Hydro model is an enhanced version of the Weather Research and Forecasting model (WRF which allows simulating river discharge. A 2-domain configuration is chosen: an outer domain at 25 km horizontal resolution encompassing the West African Region and an inner domain at 5 km horizontal resolution centered on the Tono basin. The infiltration partition parameter and Manning’s roughness parameter were calibrated to fit the WRF-Hydro simulated discharge with the observed data. The simulations were done from 1999 to 2003, using 1999 as a spin-up period. The results were compared with TRMM precipitation, CRU temperature and available observed hydrological data. The WRF-Hydro model captured the attributes of the “observed” streamflow estimate; with Nash-Sutcliff efficiency (NSE of 0.78 and Pearson’s correlation of 0.89. Further validation of model results is based on using the output from the WRF-Hydro model as input into a water balance model to simulate the dam levels. WRF-Hydro has shown the potential for use in water resource planning (i.e. with respect to streamflow and dam level estimation. However, the model requires further improvement with respect to calibration of model parameters (e.g. baseflow and saturated hydraulic conductivity considering the effect of the accumulation of model bias in dam level estimation.

    este problema consiste en la clasificación del producto en función de sus características visuales, lo que tradicionalmente se realiza de forma manual: un operario observa cada pieza y la asigna a uno de los tipos considerados en función de parámetros visuales tales como color, textura, grano, veteado, etc. Sin embargo, esta labor presenta a su vez problemas de consistencia, debidos a la subjetividad del criterio de clasificación de cada operario, y a los errores provocados por su progresiva fatiga. Los intentos de aplicar sistemas de inspección automática genéricos como los utilizados en la industria cerámica han resultado fallidos debido a que la piedra natural presenta una variabilidad mucho mayor que las baldosas cerámicas. Por ello, ha sido necesario desarrollar sistemas de clasificación específicamente diseñados para el tratamiento de los ámetros visuales que diferencian los distintos tipos de piedra natural. A continuación se describe los pormenores del sistema de visión artificial desarrollado por AITEMIN para la clasificación automática de piezas de granito en función de su tono, que permite dar una solución integral a la problemática del control de tono en la industria de elaboración y comercialización de granitos. El sistema ha sido diseñado para ser entrenado fácilmente por el usuario final, mediante el aprendizaje de las muestras seleccionadas como patrones de tono.

    To compare central corneal thickness (CCT) measured by standard ultrasound pachymetry (USP), and three non-contact devices in healthy eyes. A cross-sectional study of CCT measurement in 52 eyes of 52 healthy volunteers was done by a single examiner at Ocular Surface and Contact Lens Laboratory. Three consecutive measurements were done by standard USP, non-contact tono-pachymeter, Pentacam corneal topographer, and Anterior Segment Optical Coherence Tomography (AS-OCT). The mean values were used for assessment. The results were compared using multivariate ANOVA, linear regression, and Pearson correlation. Agreement among the devices was analyzed using mean differences and Bland-Altman analysis with 95% limits of agreement (LoA). Finally, reliability was analyzed using intraclass correlation coefficient (ICC). Mean CCT by ultrasound pachymeter, tono-pachymeter, corneal topographer and AS-OCT were 558.9 ± 31.2 µm, 525.8 ± 43.1 µm, 550.4 ± 30.5 µm, and 545.9 ± 30.5 µm respectively. There was a significant positive correlation between AS-OCT and USP (Pearson correlation = 0.957, p device, and USP. Mean CCT among USP, Pentacam and AS-OCT were comparable and had significant linear correlations. In clinical practice, these three modalities could be interchangeable in healthy patients.

    Full Text Available O Sorghum bicolor (L. Moech é uma importante forrageira de alta produção, que cresce no cenário brasileiro ainda de forma lenta em substituição ao cultivo de milho safrinha. A cultura do sorgo seria alternativa no período da seca na produção de silagem para o período das águas; contudo, o crescimento e desenvolvimento das plantas pode ser influenciado por alterações nos atributos do solo, como textura, porosidade e estrutura do solo. O objetivo deste trabalho foi analisar e caracterizar a dependência e variabilidade espacial entre atributos do solo e a cultura do sorgo forrageiro, em um Planossolo Hidromórfico no ecótono Cerrado-Pantanal. Para tanto, estimaram-se a produtividade de matérias verde e seca de forragem (MVF e MSF de sorgo forrageiro e os atributos do solo, como macroporosidade (Ma, microporosidade (Mi, porosidade total (Pt, diâmetro médio geométrico, diâmetro médio ponderado, índice de estabilidade de agregados (IEA e teor de carbono orgânico total do solo (COT, em duas profundidades: 1 (0,00-0,10 m e 2 (0,10-0,20 m. Em relação à malha geoestatística, foram realizadas 50 coletas de atributos de planta e solo em 40 ha. Isso possibilitou detectar a elevada variabilidade espacial dos atributos de planta (MVF e MSF e também os atributos do solo que mais variaram espacialmente. Com relação às variáveis que apresentaram dependência espacial, o coeficiente de determinação (r2 decresceu na seguinte ordem: IEA1, silte2, Ma1, Pt1, areia2, silte1, MSF, argila1, MVF e IEA2. Com isso, verificou-se que IEA1 apresentou o melhor ajuste semivariográfico (r2 = 0,926, com alcance de 677,0 m, e o avaliador da dependência espacial (50,6 % moderado. O silte1, porém, evidenciou o menor alcance (111,0 m e, assim, recomenda-se que em estudos posteriores o alcance mínimo a ser adotado, para esse tipo de avaliação, não deve ser inferior a esse valor em Planossolo Hidromórfico sob preparo convencional.

    Full Text Available The purpose of this study was to compare the intraocular pressure (IOP values measured with the Tono-Pachymeter NT530P (Tonopachy™ and the iCare® rebound tonometer (iCare® with those obtained by the Goldmann applanation tonometer (GAT. The right eyes of 105 subjects aged 18 to 82 years (mean age = 29.27 ± 14.67 years were assessed with the three tonometers. Central corneal thickness (CCT was measured first using the Tonopachy™ and then IOP was measured by Tonopachy™, iCare® and GAT. The data was analyzed with descriptive statistics, paired  t-test, correlation and regression analysis. The Bland-Altman method of analysis was used to evaluate agreements between the sets of data from the three devices. The CCT values ranged from 440 µm to 606 µm (mean= 518.49 ± 33.01 µm. There was little or no correlation between CCT and IOP for any of the instruments used in this study (r = 0.29 for Tonopachy™, r = 0.22 for iCare®, r = 0.17 for GAT. The mean IOP measured with the Tonopachy™ was 14.31 ± 3.57 mmHg (range 8.7 mmHg to 31 mmHg and 16.64 ± 4.38 mmHg (range 8 mmHg to 32 mmHg using the iCare®. The mean IOP measured with the GAT was 14.79 ± 3.09 mmHg (range 8.7 mmHg to 29.7 mmHg. Using the Bland-Altman method, the upper and lower limits of agreement between the Tonopachy™ and GAT, iCare® and GAT, iCare® and Tonopachy™ were 5.1 mmHg and –4.2 mmHg, 8.6 mmHg and –4.9 mmHg, 7.5 mmHg and –2.8 mmHg respectively. In 79.1% of the eyes studied, the mean IOP difference between Tonopachy™ and GAT was less than 3 mmHg and in 20.9% of the eyes, the difference was greater than 3 mmHg. However, mean IOP differences of greater than 3 mmHg were obtained by iCare® in comparison with GAT (40% and Tonopachy™ (34.3% respectively. Findings of this study suggest that the Tonopachy™ yielded IOP readings that were consistent with those of GAT values while iCare® yielded higher IOP values compared to both GAT and Tonopachy™.

    Modified asphalt in the area of road pavement in the relation of measures against flow on a road surface was introduced. The condition of road damage includes the print of a wheel, crack, and wear and semi-blown asphalt whose deformation is difficult even if temperature is increased to approximately 60 {degree}C and asphalt with rubber and resin are used to prevent these. The semi-blown asphalt is obtained by adding cut-back material to the normal asphalt, heating it, blowing air into it, and then oxidizing and polymerizing it, is harder and is more elastic than the normal asphalt, and has smaller viscosity change due to temperature change. The viscosity at 60 {degree}C was determined to be 10000{plus_minus}2000 poise according to the relationship between viscosity and crack using a large-scale execution experiment. The asphalt with rubber and resin is formed by adding modified material of styrene - butadiene copolymer and by adding thermoplastic elastomer and the former is used for preventing slide and the latter is used for preventing flow and wear. 10 refs., 6 figs., 2 tabs.

    The emulsification, manufacture, type, applications, etc. of asphalt emulsion were introduced. The emulsification of asphalt is obtained by mixing heated asphalt into an emulsification liquid where emulsifier is added to water and then agitating it. The emulsifier has both hydrophilic and lipophilic parts in the same molecule, prevents collision between asphalt particles after being arranged properly on the surface of asphalt particles, and prevent separation into water and asphalt. The emulsion is available for penetration and for mixing depending on applications and can be classified into cation emulsion, anion emulsion, and nonionic emulsion according to the property. The emulsion is mainly applied to road pavement, reaching approximately 90 % of the total manufactured emulsion. It is also used for other areas such as the filler of a slab race of each bullet train of Sanyo, Tohoku, and Jyoetsu and is also applied to the formation of a water-proof layer by spraying a high-concentration emulsion with rubber, agricultural water channels using asphalt emulsion and nonwoven cloth, etc. in civil engineering and agricultural fields. 2 refs., 13 figs., 8 tabs.

    The model experiment of a borehole electromagnetic (EM) method was carried out using the prepared waterproof sensor and materials with conductivity of 10{sup 0}-10{sup 2}S/m as medium. The 2-layered structure ground model was prepared by filling a water tank with saturated brine of nearly 20S/m up to 30cm. Square wave current was sent from an amplifier to a transmitter coil, and electro motive force induced in a receiver coil was measured. Although numerical simulation is widely used for EM method, analog model experiment is also effective. For the receiver coil installed in brine, preventive measures from short-circuit and water were prepared. Electro motive force was measured at receiver intervals of 1cm and at 0-10cm in depth using a bar carbon model immersed in brine by 5cm in depth under resistivity contrast of 1000 times. In addition, to reduce the resistivity contrast between brine and body, the model experiment was carried out using immersed thin metallic sheet structure with conductivity similar to that of ore under resistivity contrast of 250 times. The effect of medium on both models was thus clarified. 4 refs., 10 figs.

    A model experiment on the well electromagnetic induction method was studied. Experimental apparatus consisted chiefly of A/D boards of 16 bit and 100 kHz. In the transmitting part, the transistor inverter and relay switch controlled by computer with car battery as current source generate rectangular wave current and make it run to the transmitter loop. In the receiving part, after electromotive force induced to the receiver coil was amplified by amplifier, it is A/D converted and recorded by computer. As a result of the experiment, the depth, plane position and shape of the structure could be caught by studying data on the well and earth surface together. Further, it was confirmed that in case the disk tilted, the response regularly changes according to the tilt. Moreover, it was found that even in case the structure is just under the inside of the transmitter loop, the thickness and tilt of the structure are influenced by the positional relation with the receiver loop. 2 refs., 18 figs.

    Flight test results of such navigation sensor systems as MLS (microwave landing system), GPS(global positioning system) and INS (inertial navigation system) on the Dornier-228 research aircraft in 1990 were reported, which tests have being promoted by National Aerospace Laboratory (NAL), Japan to develop unmanned approach/landing (A/L) navigation sensor systems for the future spaceplane HOPE. The measured data corresponding to a WGS84 (world geodetic system 1984) navigation coordinate system were evaluated, and the reference orbit was also prepared by laser tracker analysis. The navigation sensor systems such as MLS were evaluated on the basis of CMN (control motion noise) or PFE (path following error), and preliminary calculation was also conducted for a GPS-INS hybrid system. As experimental results, several data were gathered for each sensor system resulting in possible data comparison between the sensor systems, and the feasibility of the GPS-INS hybrid system was also confirmed. 35 refs., 49 figs., 22 tabs.

Teores de carbono orgânico total foram superiores nas camadas superficiais no campo, quando comparados com a floresta. Dados de delta13C associados à cronologia do 14C indicaram predomínio de plantas C3 no início do Holoceno em ambos os ecótonos. Entre aproximadamente 7.000-3.000 anos AP verificou-se a influência crescente de plantas C4, indicando regressão da floresta com possível presença de um clima mais seco. A partir de aproximadamente 3.000 anos AP os dados sugeriram expansão da floresta provavelmente relacionada ao retorno a um clima mais úmido. A presença de algumas espécies características da borda, como a Sclerolobium paniculatum e Himatanthus sucuuba, nos campos, sugere o atual avanço da floresta sobre os mesmos.

    Introduction is made of space photovoltaic power generation which is the ultimate clean energy source. This is a system to obtain electric energy from the solar cells placed on a geostatic orbit and transmit the power onto the earth by microwave. The US formulates a plan of placing 60[times]5GW power generation satellites to obtain 300GW power on the earth in 2000. As for the scale of space structure, the array of solar cells is dimensionally 10km[times]5km and the power transmitting antenna is 1km in diameter. The electric energy is amplified to microwave and power-transmitted by wireless onto the earth. The ground rectenna which receives it is dimensionally 10km[times]13km. The biggest difficulty consists in transportation of construction materials onto the orbit. In Japan, activity comprises three matters, which are research committee organized three years ago by the Agency of Industrial Science and technology, 10MW class model conceptually designed by the Institute of Space and Astronautical Science, and experiment conducted by Kyoto University on the power transmission by wireless. Pertaining to the research on the space power generation, the following two points are judged still unclarified: Reason for which the electric power companies did not apply the power transmission by wireless regarded as high in transmission efficiency.

    The materials except cement, water and aggregate added into the cement paste, mortar or concrete before the execution of smashing are called mixed materials. The mixed materials are indispensable to the concrete for improving the quality of the fresh concrete as well as the hardened concrete; providing the characteristics suitable for the operation; and increasing the economy. In this paper, the main mixed materials including fly ash, which is the by-product in coal thermoelectric power station; silica fume; micropowder of slag in blast furnace; expansive materials and so on are described summarily. Especially, silica fume is the by-product, which are the super micro-powders with the average size around 0.1 micrometer, collected by the dust-collector from the waste gas generated during the manufacture in the electric furnace of ferrosilicon, which is an alloy iron, or silicon metal used as the deacidificating and desulfurizing agents in the steel production.

    A discussion was given on an `energy autonomous house` which utilizes more effectively photovoltaic power generation, solar heat and light in designing a wooden house to be built by using the conventional construction method. According to the plan, photovoltaic power generation modules and heat collectors are installed superimposed on a roof facing south. Heat-collected air is sent below the floor and the heat is stored in the concrete in winter, utilized as the floor heating type room heater. The hot air is used for hot water supply in other seasons. The building is of two stories with a total area of 118 m {sup 2}, and the photovoltaic generation capacity is 3.48 kW. The photovoltaic generation amount was calculated from insolation forecasted by the AMEDAS system, and energy balance of this house was estimated. The result therefrom may be summarized as follows: total energy supplied reached 11.6 Gcal, signifying that about 10.8% of the energy irradiated onto the building is utilized; ratio of the photovoltaic and solar heat utilization is 27% versus 73%; and energy consumption in this house was estimated and calculated from actual results, airtightness and adiabatic performance of old houses, whereas the energy autonomous rate has reached 92.8%. 5 refs., 2 figs., 8 tabs.

    Aluminum, GFRP and composite of aluminum coated with carbon as structural materials for wind turbine blades were bending-tested, to improve blade bending stiffness, understand stress conditions at each position, and clarify structural dynamic strength by the bending-failure test. It is possible to estimate stress conditions at each position from the test results of displacement and strain at each load. The test results with GFRP are well explained qualitatively by the boundary theory, known as a theory for composite materials. The test gives reasonable material strength data, useful for designing wind turbines of high functions and safety. The results of the blade bending-failure test are in good agreement with the calculated structural blade strength. It is also found that GFRP is a good material of high structural strength for wind turbines. 8 refs., 6 tabs.

    Nonlinear full-wave tomography (FWT) is under investigation to improve the estimation accuracy of Vp/Vs distributions. Full-wave tomography is one of the underground structure exploration methods mainly using Tarantola`s nonlinear local optimization method (LOM). Numerical experiment for FWT was carried out assuming relatively weak nonlinear underground structure. In the case of inversion by local optimization method, adequate preconditioning is important. Utilization of geological information is also effective in estimating low-frequency components of a model. As far as data are obtained under proper observation arrangement, even in actual field, precise estimation of Vp/Vs distributions is possible by FWT using explosion in a hole as wave source. In full-wave tomography, selection of observation arrangement is essential for both Vp and Vs. However, the proper arrangement is different between Vp and Vs. Approach to different analyses for Vp and Vs is also necessary by using only proper data for Vp and Vs among obtained data sets. 4 figs.

    This paper describes the MT surveying conducted at the vicinity of a deep well (WD-1) in the Kakkonda geothermal area. For the MT surveying, the interval between measuring points was 300 m. Electric field dipole with a length of 300 m was given in the direction of traverse line, and that with a length of 50 m was given in the direction perpendicular to the line. Three components of magnetic field were measured using induction coil. Frequency band of the data was between 0.0005 Hz and 300 Hz. Characteristics of specific resistance model obtained from the MT surveying were illustrated. Low specific resistance zone less than 30 ohm-m was observed in the shallow zone below the altitude 0 m. This zone was comparable to the distribution of montmorillonite. High specific resistance anomaly was analyzed at the western half of the traverse line in the altitude between 0 m and -2000 m, which corresponded to the collective part of focuses. The bottom surface of the anomaly agreed well with the upper surface of neo-granite, i.e., the lower limits of earthquakes. Low specific resistance was observed in the altitude below -2000 m. 17 refs., 5 figs.

    The present report outlines the multi-story precast prestressed concrete earthquake-proof wall (PC shear wall system). The PC shear wall is a precast wall which internally contains the columns and beams as a unit. Therefore, the present system integrates the walls, columns and beams without beam-framing installation for the intermediate stories. It can simplify the concreting in site and ease the construction of building. For the system development, experiment was made on the deformation, sliding, yield strength and destruction state of the shear wall. Used were four types of test unit which are different in both reinforcement and connection methods. The test force was given by a hydraulically drawing jack. In the experiment, the four types were compared in destruction state, relation between load and deformation, yield strength, and strain of main column reinforcing bars and wall connection reinforcing bars. PC shear wall system-based design was studied from the experimental result. The shear wall in which there occurred both bending and shearing deformations was modeled by changing to a brace unit. Divided into bending deformation and shearing deformation, the deformation was calculated, which concluded that the shearing deformation dominates in the present system. 15 figs., 4 tabs.

    Described herein are the current status and development of insecticides for domestic purposes. For aerosol type cockroach-killing insecticides, oily type is predominant in Japan whereas aqueous type in USA and other countries. They are mixtures of knockdown agents and killing agents, the former being used for their immediate and lethal effects whereas the latter for their lethal effect. In 1996, agents showing high knockdown effects, such as pyrethroids, are registered. Fumigants are used in closed spaces, which are ventilated after they are used. Bait agents contain inducing agents. Recently, ticks become social problems as an allergy source. The insecticides are generally used to remove them, although physical methods, such as cleaning and heat treatment, are effective. They are centered by aerosols and fumigants, but insecticidal sheets are used to some extent. Fleas coming from pets also cause problems. Increased resistance of insects to insecticides has led to development of new types of insecticides, such as those based on organophosphates and those aimed at prevention of their metamorphosis. Commercial insecticides are safe, as long as they are produced in compliance with the Pharmaceutical Affairs Law and used correctly. Nevertheless, however, researches for safer countermeasures against insects are needed. 3 refs., 2 figs., 1 tab.

    Non-contact Tonopachy NT-530P (Nidek Co., LTD) provides intraocular pressure (IOP) and central corneal thickness (CCT) measurements. This study assesses the reliability and repeatability of its IOP measurements in young healthy adult subjects. IOP was determined in the right eye of 64 healthy patients using Tonopachy followed by the Canon TX-10 non-contact and Goldmann applanation (GAT) tonometers. Tonopachy IOP measurements were corrected (Tonopachy-C) or not (Tonopachy-NC) by the instrument for central corneal thickness. Central corneal thickness measurements provided by Tonopachy were also used to correlate (Pearson's coefficient) central corneal thickness with the GAT and Canon TX-10 IOPs. Repeatability of Tonopachy and GAT was assessed in the right eye of 31 subjects in two separate sessions one week apart. Differences between pairs of instruments and between sessions were determined using Bland-Altman plots. The coefficient of repeatability was calculated as the 95% limits of agreement (LoA) of differences between the two sessions. Tonopachy-NC, Tonopachy-C, Canon TX-10 and the Goldmann tonometers showed a mean IOP of 14.62, 15.64, 15.02 and 14.68 mmHg, respectively. Tonopachy-NC and Canon TX-10 readings did not differ significantly from the Goldmann (p > 0.05), with close agreement with both tonometers (GAT versus Tonopachy-NC: -3.84 to 3.96 mmHg; Goldmann versus Canon TX-10: -4.75 to 4.07 mmHg). Tonopachy-C readings differed significantly from Goldmann (mean difference -0.96 mmHg, p = 0.001, LoA from -5.09 to 3.17). Coefficients of repeatability were ± 3.70, ± 3.14 and ± 3.33 mmHg for GAT, Tonopachy-NC and Tonopachy-C, respectively. Central corneal thickness measured with Tonopachy was 530.42 ± 34.96 μm. There was a significant correlation between central corneal thickness and IOP for all tonometers except Tonopachy-C. Reasonable agreement was observed between the Goldmann and Tonopachy. This instrument provides reliable and repeatable IOP measurements not influenced by central corneal thickness. The Tonopachy-NC and Canon TX-10 offer similar reliability compared to the Goldmann applanation tonometer in a young normotensive population. © 2013 The Authors.

    For artificial coalification, condensation reactions of aromatic ring and activated compounds produced by dehydrating reaction of glucose were studied experimentally. In heat treatment experiment in water, three reaction specimens such as glucose, glucose and phenol, and glucose and benzaldehyde were fed into an autoclave together with distilled water, and subjected to reaction at 180{degree}C under spontaneous pressure for 50 hours. In hydrogenation experiment, the specimens were fed into an autoclave together with tetradecane and sulfurization catalyst, and subjected to reaction at 350{degree}C under initial pressure of 9.8MPa for 2 hours for gas chromatography (GC) analysis of products. As the experimental result, the reaction between glucose and aromatic ring in heat treatment in water occurred between aromatic ring and active fragment with a mean carbon number of 4-5 produced by decomposition of glucose. The reactivity was higher in benzaldehyde addition than phenol addition. 3 refs., 4 figs., 1 tab.

    This paper describes a study of a security method of protecting inside network computers against outside miscreants and unwelcome visitors and a control method when these computers are connected with the Internet. In the present Internet, a method to encipher all data cannot be used, so that it is necessary to utilize PEM (Privacy Enhanced Mail) capable of the encipherment and conversion of secret information. For preventing miscreant access by eavesdropping password, one-time password is effective. The most cost-effective method is a firewall system. This system lies between the outside and inside network. By limiting computers that directly communicate with the Internet, control is centralized and inside network Security is protected. If the security of firewall systems is strictly controlled under correct setting, security within the network can be secured even in open networks such as the Internet. 35 refs., 3 figs.

    Full Text Available This article is part of the research project, “Youth musical mediations,” that explores the appropriation of alternative means of communication which allow the young to develop identities sharply differentiated from those the adult world. In particular, the article examines the world of hip hop in Medellín and the ways that youth participate in it. To follow key trajectories of women in hip hop, their voices, feelings, and memories must be uncovered. This will allow us to see how the few women who are currently part of hip hop scene in Medellín and Colombia enter, move through, and persevere in it. Since women constitute only a small percentage of the youth who live and remake hip hop in Medellín, it is important to understand how they manage to live in a male-colored world. If hip hop is about strength, denunciation, confrontation, and resistance, it seems that these qualities are more appropriate for men than for women

    Price negotiation on metallurgical coal imported by Japan in fiscal 1994, which started in December 1993, came to a conclusion at once over nearly all brands of both countries of Australia and Canada, taking a conclusion of three brands of Canada on 24th of January as a turning point. The width of reduction in price was 3.85$ (7.81%) at heavy caking coal, 3.50$ (8.00%) at semi-caking coal, and 3.30$ (8.30%) at combined non- and slight caking coal. Reduction in steel production in Japan and abundance in coal production in the world produced this result. The conclusions mentioned above were followed by conclusions in negotiation on metallurgical coal of South Africa and China. Concerning steam coal, negotiation on an export/import treaty between China and Japan was concluded on 29th of March as the head of a series of steam coal shipped in fiscal 1994. The quantity was increased by 800 kton than in fiscal 1993, the price was reduced by 3.30$ or 3.20$ (9.2% or 9.4%). Negotiations on steam coal of Australia, Indonesia, and the Western U.S. were concluded after hard negotiations, although negotiation is being continued for South Africa steam coal. 1 fig., 7 tabs.

    This paper described the Furuto-sui(goaf water) in Chikuho Coal Field where coal mining was made for 100 years, remaining mined traces in wide range. This is called Furuto and water collected in or passed through Furuto is called Furuto-sui. The Furuto was made by coal layer mining and the distribution is coincident to the geological structure of coal layer. This Furuto structure is shallower to westward direction, deeper to eastward direction and identical to the north-southward direction. The Furuto can be said as the artificially built reservior for ground water. The coal mining was perfectly stopped in 1976 and the Furuto-sui filled in mined cavities. At low ground area, springs or humid areas appeared. Water quality is diverse but the typical ones are the type of Ca-SO{sub 4} of 3-5 pH, type of Na-HCO{sub 3}*SO{sub 4} of 8-9pH, and type of Na-SO{sub 4} of 7 pH. A part of Furuto-sui is utilized as the water for home use but must be utilized much more as water reservior. 12 refs., 9 figs.

    The Engineering Test Satellite-VI is a large composite test satellite weighing two tons to perform different communication experiments. Adoption of the multi-beam satellite communication system has made possible to increase the transmission capacity, reduce the sizes of earth stations, and utilize frequencies more effectively. This paper describes the configuration of the relaying devices mounted thereon, the newly developed circuit technologies, and their reliability. The multi-beam satellite communication system mounts a number of transponders, with the frequency bands used divided into the 2.6/2.5 GHz band between the moving body and the satellite, the 6/4 GHz band for the channels between the earth stations and the satellite, and the 30/20 GHz band for the fixed communications. These arrangements were intended to achieve large size reduction as a result of applying the integrated circuit technology. The transmitters and the receivers corresponding to each beam are connected by using the satellite switches (16 inputs {times} 12 outputs). The parts used were general purpose ones rather than those specified in the MIL standards because of their number having reached so huge. Their reliability was ensured by long-term burn-in operations. 5 refs., 6 figs., 1 tab.

    Mathematical structure of a vessel arrangement program was discussed in order to learn roles of container ships in ocean transport systems among China, NIES/ASEAN countries and Japan. Formulation is possible on a mathematical handling method for sailing route connection diagrams between ports, a transport network to indicate container movements, a service network to indicate sailing routes, and a network generalizing them. This paper describes an analysis made on the container transport system between Japan and China, taken as an example. Four ports were selected each from Japan and China, and the statistical database for fiscals 1996 and 1994 was utilized to set models for: (a) the liner network system with transshipment at the port of Shanghai and (b) the cruising route system going through the ports of Yokohama, Nagoya and Kobe. A hypothesis was set that a consortium (coordinated ship allocation) can be implemented ideally and completely. The transport network (a) is lower by 10% in total cost than the transport network (b), resulting in 1.6 times greater productivity. Actual service network is closer to the network (b), but the system can be utilized for discussing guidelines on vessel arrangement programs with which shipping companies pursue better management efficiency under a condition that the consortium can be formed. 10 refs., 6 figs., 2 tabs.

    An energy saving inverter type air-conditioner was introduced. It is important to increase the efficiency in the low capacity zone below the rated capacity to realize the energy saving. For the reduction of peak, improving the efficiency in the high capacity operation is also necessary. The power consumption in compressor and in inverter is about 90 % of the total power consumption in air-conditioner. The other 10 % are distributed to the fan motor and the control unit. For achieving the energy saving, the reduction of this 10 % part is also necessary because this 10 % part is constant regardless of the capacity of air-conditioner. The compressor motor was modified to the brushless DC motor with rotor position detecting device to improve the rotor structure and the position detection system. The heat exchanger was changed to a room heat exchanger with slit pattern. For the outdoor heat exchanger, the complex curvature blade fan was adopted. The control system of air-conditioner was changed. The PMV was previously learned and input in the microcomputer to calculate the data. Resultantly, the power consumption was reduced by about 20 % as compared with the conventional air-conditioner. 10 figs., 1 tab.

    To compile a base map of gravity in Hokkaido, gravity was measured in central Hokkaido where gravity data are absent. Gravity anomaly was made clear in this region. Survey area was 87 km in the east-west and 224 km in the north-south. A topographic map with a scale of 25,000:1 was initially used for determining location and altitude of gravity measuring points. Since the GPS survey was found to be very useful for gravitational observation in the region of Hyogo-ken Nanbu Earthquake in 1995, the GPS has been used in this survey from 1996. Based on new measurements at 2,148 points in addition to existing points, Bouguer anomaly map was made, and density distribution of surface layer of the crust was estimated. As a result, the gravity anomaly pattern in the north-south direction and gravity anomaly in basins and volcanoes were made clear. Quantitative analysis is to be conducted using these gravity data. Using these gravity data, the density distribution of surface layer of the crust was estimated. This distribution agreed well with the geological map in this region. 4 refs., 6 figs.

In this study, effects of the state of hydrofoils and velocity on the hull were fluid-dynamically investigated through the numerical calculation by means of Rankine source method using a Wigley model with two hydrofoils. Before considering the model with hydrofoils, the attitude change of a hull without hydrofoils during traveling in high-speed was examined. For the high-speed ship, various measuring systems have been conceived due to the large change in its attitude. The Wigley model has been used for the numerical calculation when considering the attitude change in the medium- and low-speed regions. In this study, resistance tests without constraining the sinkage and trim were conducted using a Wigley model in the high-speed region around Fn=1.0, which have not been usually conducted. The attitude changes were compared with the numerical calculation results by the Rankine source method. The wave making resistance and attitude change of the Wigley model with hydrofoils were also calculated. 12 refs., 10 figs.

    The paper described the positioning and new development of clean coal technology. Coal is an important resource which supplies approximately 30% of the energy consumed in all the world. In the Asian/Pacific region, especially, a share of coal in energy is high, around 60% of the world, and it is indispensable to continue using coal which is abundantly reserved. Japan continues using coal as an important energy among petroleum substituting energies taking consideration of the global environment, and is making efforts for development and promotion of clean coal technology aiming at further reduction of environmental loads. Moreover, in the Asian region where petroleum depends greatly upon outside the region, it is extremely important for stabilization of Japan`s energy supply that coal producing countries in the region promote development/utilization of their coal resources. For this, it is a requirement for Japan to further a coal policy having an outlook of securing stable coal supply/demand in the Asian region. 6 figs., 2 tabs.

    With an objective to perform three-dimensional analysis with high accuracy in using the electromagnetic exploration method, characteristics in electromagnetic response were analyzed, and conditions for acquiring necessary data were discussed. The discussion defined a parameter called `response anomaly` which uses response from media to standardize response only from substances with abnormal resistivity. The receivers were located uniformly on the same plane, and the response anomaly was derived from electromagnetic response from each of the three horizontal and vertical components at each receiving point, which was expressed as a contour map. The parameter for the abnormal body was consisted of location and resistivity contrast with media. Discussions using the contour map were given on the response when these factors for the parameter were varied. As a result, it was found that the response anomaly appears in the form that reflects the abnormal body, and the response anomaly of the horizontal component is superior in terms of being large. It was also referred that, as a requirement for the abnormal body which gives larger impact from the electromagnetic response, the abnormal body should have lower resistivity than that in the media, and resistivity contrast with the media should be greater. 2 refs., 7 figs., 1 tab.

    Discussions were given on properties of soap prepared from waste edible oil. A fresh oil, and soybean and rapeseed oils with different thermal oxidation degrees were used to prepare soap. On the other hand soap was made using wast edible oil after used at home. Soap made from fresh oil and thermally oxidized oil under a 3-hour heating at 90[degree]C has less non-saponified fat. Soap made from a large amount of waste edible oil. taking 34 days had much residual fat, proving these were insufficiently saponified. Slightly higher values were recognized in the soap from fresh oil for anisidine value (An.V), carbonyl value (CV), peroxide value (POV) and the content of oxidized fatty acids than in fresh oil itself. On the other hand, the An.V and CV in the soap made from thermally oxidized oil were lower than those for thermally oxidized oil itself. The An. V and CV in the soap made from waste edible oil were higher than those in waste edible oil itself. As the soap has been stored, all of the soap showed increase in the An.V, the CV, the POV and the oxidized fatty acid amount, but the fatty acid composition showed no change. 9 refs., 4 figs., 4 tabs.

    Fiber forming, scutching and knitting processes in recent years are performed three to five times faster than in the conventional processes. Associated therewith, oil solutions are taken importantly for their stability and workability, such as smoothing properties, heat resistance and abrasion resistance. On the other hand, difficulty is increasing in removing the oils after scutching and knitting. This paper explains basic rinsing activities required in oil removal, and describes various test characteristics and compatibility of various high-rate oil removing scouring agents. An oil-in-water rinsing mechanism relies upon comprehensive actions of a surfactant in wetting, permeation, emulsified dispersion and solubilization. The most importantly taken among them is the emulsifying action, which largely depends upon its chemical structure. Therefore, for a high-rate oil removing scouring agent, creation of activators is required that make the above basic characteristics and activities compatible for various applications. For example, the above product covers a great variety of kinds for diverse applications, based on non-ionic and anion-based activators. 6 figs., 20 tabs.

    This paper outlines the newly prepared geothermal gradient map (GGM) of Hokkaido which is important for survey on geothermal and hot spring resources. The temperature data of 687 wells were compiled by data collection and field survey. The geothermal gradient was calculated from the ratio of the temperature difference between the bottom (deepest well log) and the ground surface (10degC) to a bottom depth. GGM was prepared using data of 85 wells which show real geothermal temperatures through conductive temperature profiles, or SBHT (static bottom hole temperature) calculation is possible. Geological profiles were classified into three types based on base rocks. The thermal structure of GGM was clearly divided into a high geothermal gradient over 10degC/100m, and a low one within 3degC/100m. The former showed active volcano and high geothermal areas, while the latter showed a volcanic front arc area. This underground temperature structure relates to the formation process of volcanos and the origin of magma, and is also similar to the trend of a crust thermal flow rate. The geothermal gradient increases with a decrease in Curie point depth. 26 refs., 10 figs., 2 tabs.

    Since the electric industry has grappled with a prevention of the environmental pollution such as the air pollution and water contamination as a forerunner in case of construction and operation of the power facilities, and at the same time has conducted actively the environmental conservation countermeasures, it has consequently achieved the environmental conservation level as a top level in the world. On the other hand, as for the emission quantity of CO2 relating to the earth warming, the power field occupies about one fourth of total Japan. Therefore the electric industry should aim at the electric energy supply considering the influence on the environment, such as the power supply structure to restrain CO2 emission as less as possible, higher efficiency of equipments, higher efficiency of energy utilization by using the unused energy and so forth. In addition to it, the consumer side should aim at the social structure with a recycle type such as saving resources and saving energy, and aim at changeover of life style. It is hoped to conduct the overall measure including the items mentioned above. In this report, the recent trend of earth enviromental problems, grappling with the environmental problems as a forerunner such as the prevention measure of air pollution in the thermal power plant, etc., and the correspondence to the earth warming problems are outlined. 11 refs., 9 figs., 3 tabs.

    Structure and design of single suspension PC cable bridge, which is first kind of high way bridge in Japan and aiming to start for general use by March, 1993, are reported. As a construction outline, main construction quantity and general layout of the whole bridge together with the selective detail and characteristics of the diagonal member, tower, main girder and tower support member, are cited. Design conditions( load, materials, allowable stress and others ), basic plan of the design, and structure analysis( surface stress framed structure analysis, stereoscopic framework analysis and FEM analysis of local stress ) are explained. Design of structure member like main girder is based on diagonal member tension, wave shearing force, level of diagonal strain stress, bending stress when diagonal member anchors the deformed main tower caused by living load during earth quake, principal stress of main tower junction and local stress etc. Main tower support member design is based on the results of corbel shearing force at varied cross section and main stress, and diagonal member design is decided by allowable stress. Diagonal member anchorage traverse beam design depends on bending moment of traverse beam and shearing force. 3 refs., 15 figs., 1 tab.

    Anisotropy has been investigated using S-wave as a technique for detecting fractures. In this study, fundamental experiments were carried out with slightly changing the measuring conditions at a place where anisotropy was expected. This paper describes the fundamental data acquisition of anisotropy analysis using S-wave, and a part of the results. The experiments were conducted on the agricultural road in Yamadera district, Matsuyama-machi, Yamagata Prefecture. Two flat unpaved roads meeting at right angles were used as traverse lines. In this place, several reflection surfaces were certainly detected by P-wave, and anisotropy of S-wave was confirmed from the velocity of refracted wave of S-wave. Data were processed for individual traverse lines meeting at right angles. Firstly, signal sweeping, correlation, and vertical superposition were made. Six kinds of data were prepared, i.e., three-component receiving records of data at 0{degree} of generating direction and three-component receiving records of data at 90{degree} of generating direction. Records of T-component at 0{degree} and R-component at 90{degree} were used for processing of the seismic reflection method. These records would be considered to be data of SH-wave and SV-wave, respectively. 4 figs.

    A system for exploration of active-faults by seismic reflection profiling method was introduced at Earthquake Research Institute, University of Tokyo. A test-run was conducted to check the performance of this system at Ranzan, Saitama Prefecture. This paper describes the confirmed performance of mini-VIB as a wide band frequency seismic source, the quality of data obtained using a digital data acquisition system, and problems for data processing of fault exploration in the future. For the test-run at Ranzan, two-dimensional exploration was conducted by the quasi-three-dimensional data acquisition method using three geophones of 8 Hz, 28 Hz, and 40 Hz, simply arranged in parallel on the measurement line. Using an active seismic vibrator, mini-VIB, data acquisition of faults in the wide band frequency was achieved, which would result in the highly accurate imaging. Operation of data acquisition and processing systems is easy, and the system can be also used as a kind of black box. The existing methods are to be used sufficiently as a tool for imaging of faults. Further research for accumulating experience may become necessary toward the extension of the system expected in the future. 5 refs., 6 figs.

    A space experiment on glass melting under microgravity was performed in a space shuttle in September 1992. The experiment has been intended to make glass from glass material floating in air by heating and melting it with light and an acoustic levitation furnace. The acoustic levitation furnace used in the experiment has been arranged so that a sound wave from a speaker makes a steady wave in a cylindrical quartz glass core tube with a length of 16 cm and a diameter of 4 cm, and a test sample can be retained floating in a valley of central wave pressures. The test sample retained floating has been collected and heated by light from a 500-W halogen lamp. Behavior of molten glass liquid under microgravity has been investigated. The glass material powder spheres have been melted completely and made into glass without crystallization. With regard to flows generated in the test sample placed in the acoustic levitation furnace, a glass spot containing cobalt oxide has been attached onto part of the test sample surface for observation. As a result, the spot has been incorporated in the glass without developing diffusion. 6 refs., 4 figs.

    Although large tank slip, as observed in Alaska in 1964, was not reported in the Hyogo Nanbu Earthquake, tank slip becomes a major concern in seismic engineering. In the case of a non-uplifting tank, ifs slip behavior can be accurately described by the simple analytical model which consists of a single degree of freedom on a potential sliding mass (SDOF slip model). Employing friction force during slip, the governing equations of the SDOF slip model are formulated as a discontinuous linear vibration system. From the analogies between the SDOF slip model and the tank, the physical quantities which correspond to the SDOF slip model are determined in accordance with the values which are specified by the seismic design code for the tank. Comparison of the experimental results of the model tank slip with the analytical results based on the SDOF slip model corroborates ifs applicability to the tank slip with sufficient accuracy.

    Vibration characteristics of the semi-spherical shell fixed in water with bidirectional curvatures were studied experimentally. Various marine structures have been devised as relay station for life spaces or submarine resource excavation. As compared with land structures, marine structures are constantly under a severe condition subjected to hydrostatic pressure, and requires advanced technologies. The experimental result, numerical computation result by analytical code DASOR (Dynamic Analysis of Shell of Revolution) and theoretical analysis result were compared with each other. FEM and BEM were used in DASOR computation for the axisymmetric thin semi-spherical shell and circumferential liquid, respectively. Due to an added mass effect, the natural frequency decreased with an increase in water level regardless of mode orders. However, the water level over the top of the semi-spherical shell caused the nearly constant natural frequencies of 30-40% of that in the air. The computation result by DASOR well agreed with the experimental result demonstrating its validity. 4 refs., 13 figs., 1 tab.

    Large soil tank developed for shearing experiments is used to study the horizontal movement of piles in earthquakes. The system comprises a soil filled (8m deep) tank, pile head loading jig, and 6 actuators. The soil tank is fabricated of 40 layers of 20cm-high iron frames of inner dimensions 2.5mtimes2.5m, and it is filled with soil that is to simulate the ground. The frames are divided into 4 groups each containing 10 frames, and the frames in each group are coupled with each other, so that all the frames in one group will move horizontally when the topmost frame in the group is moved horizontally. An actuator, which travels horizontally ganging with a computer, is mounted on the top frame in each group, and this setup enables the arbitrary simulation of ground deformation in the horizontal direction in an earthquake. The pile head loading jig, driven by 2 actuators, can keep restraining the pile head from rotation while applying load or deforming force to the pile head as desired in the vertical and horizontal direction. Experiments conducted using this system involve the force imposed on a pile in the soil tank by ground deformation and the resultant pile behavior including breakdown. 9 figs.

    Investigations and discussions were given by using P-S logging on anisotropy of refracted waves in the fundamental experiments conducted in the Matsuyama town, Yamagata Prefecture. In the investigations, S-wave was transmitted into two to three directions at four locations in total: one at the opening of a well with a depth of 100 m and three locations having offset of 50 m from the well opening, and anisotropy of direct waves in the depth direction was investigated. Data were recorded on the ground at the same time by using a 3-component receiver. As a result of the experiment, detection of the anisotropy by means of measurement inside the well was found more difficult than anticipated due to anomaly in the refracted waves, hence no clear velocity anisotropy has been observed. It appears that no azimuth anisotropy exists at depths shallower than at least 24 m. No anisotropy due to incident angles was made clear in the present experiment. Offset recording experienced poor S/N ratio, having made the data analysis difficult. The data for zero offset do not harmonize with the refracted wave analysis on the data derived by using the reflection method, whose cause requires further discussions. 4 figs., 2 tabs.

    Mixed-compression type axisymmetric air intakes for ATREX engine have been tested in the supersonic wind tunnel from Mach 0.5 to 4 since 1993. The throat area of the intake can be variable with a translating center spike to accomplish starting and off-design operation since the ATREX intake must work well over the wide flight Mach number up to 6. Here are presented effects of the intake design Mach number, the air bleed from a center spike and/or a cowl around the throat, an angle of attack and blunt nose of the spike on the intake performance characteristics, that is total pressure recovery and mass capture ratio. It is found that bleeding from the center spike and the cowl influences mainly on total pressure recovery and mass capture ratio respectively. The advantage of rounding properly off the spike nose is confirmed. Small center spike cone angle and/or blunt nose is sensitive to the angle of attack. (author)

    It is important to cool a photovoltaic (PV) panel, because increased panel temperature is accompanied by decreased power generation efficiency. The authors have proposed a PV power generation system combined with an adsorption chiller driven by low-temperature heat, and simulated temperature changes during the desorption cycle, where the chiller utilizes endothermic reactions of an adsorbent during the desorption cycle. Described herein are results of the tests carried out to validate possibility of controlling panel temperature increase. The system consists of the PV panel with which a bed packed with an adsorbent is monolithically combined, condenser and evaporator. It generates power during the daytime by sunbeams, and provides low-temperature heat during the nighttime by the evaporator. In particular, ice can be produced when methanol and activated coal are used as the adsorbate and adsorbent. It has an advantage of effective utilization of energy as the heat source, which has been merely dissipated by the conventional system in the air. Such a system is expected to be useful for promoting effective utilization of solar energy and for peak power shaving in summer. The initial targets are achieved by the tests. 4 refs., 10 figs.

    Difficult area in this context means an exploration-difficult area supposed to store oil/gas but retarded in exploration for the lack of knowledge about the geological structure due to poor quality of available seismic survey records. Discussed in this paper is a survey conducted into an area covering the southern part of Noshiro-shi, Akita-ken, and Yamamoto-cho, Yamamoto-gun, Akita-ken. An area size suitable for data collection at a target depth of 2500m is determined using an interpretation structure compiled on the basis of available well data and 2D seismic survey data. The plan for siting shock points and receiving points is modified case by case as restrictive factors come to the surface (resulting from the complicated hilly terrain, presence of pipes for agricultural water, etc.). The peculiarities of seismic waves in the terrain are studied through the interpretation of the available well data and 2D seismic survey data for the construction of a 3D velocity model for the confirmation of the appropriateness of the plan for siting shock points and receiving points. Efforts are exerted through enhanced coordination with the contractor to acquire data so that a technologically best design may be won within the limits of the budget. The quality of the data obtained from this experiment is in general better than those obtained from previous experiments, yet many problems remain to be settled in future studies about exploration-difficult areas. 4 refs., 4 figs., 1 tab.

    If the borehole radar is utilized for detection of buried pipes, the underground radar measurement becomes possible even in the situation where the mesurement on the earth surface is difficult, for example, such a place as under the road where there is much traffic. However, since buried pipes are horizontally installed and the existing borehole radar can send/receive only vertical polarization, the measurement conducted comes to be poor in efficiency from a viewpoint of the polarization utilization. Therefore, by introducing the polarimetric borehole radar to the detection of buried pipes, a basic experiment was conducted for the effective detection of horizontal buried pipes. Proposing the use of a slot antenna which can send/receive horizontal polarization in borehole in addition to a dipole antenna which sends/receives vertical polarization, developed was a step frequency type continuous wave radar of a network analyzer basis. As a result of the experiment, it was confirmed that reflection from buried pipes is largely dependent on polarization. Especially, it was found that in the slot dipole cross polarization mesurement, reflection from buried pipes can be emphasized. 4 refs., 5 figs.

    In order to clarify a humification process in the early stage of coalification, the nitrogen functionality of prepared glucose-glycine condensate was studied experimentally. In experiment, the condensate was prepared by heating the mixture of glucose, glycine and water in a autoclave at 130{degree}C for 50 hours, and furthermore heating the produced solid material in water at 300{degree}C. After the condensate was hydrocracked, the fraction, condensate and hydrocracking residue were analyzed by elementary analyzer, {sup 13}C-NMR, XPS, FT-IR, capillary GC-FID/NPD and GC-MS. As a result, the glucose-glycine condensate could be arranged on the basis of three types of nitrogen such as pyridine, pyrrole and quaternary amine type. Pyridine type nitrogen increased, while quaternary amine type one decreased with an increase in heating treatment temperature. Rich pyrrole type nitrogen and poor pyridine type one were found in light nitrogen compounds in hydrocracked products. 2 refs., 4 figs., 2 tabs.

    With an objective to elucidate relationship between human functions related to gravity in space and the gravity, simultaneous measurement was carried out on impulsive eyeball motions and antigravity muscles. The measurement used a non-polarized electrode mounted on a prescribed position on skin. The subject is a spacecraft crew who was subjected to an experiment in space in 1992. Data obtained during the flight were analyzed, and the following findings were obtained: the eyeball motions are performed accurately in terms of space and time; potential time relative to the target appearance time showed greater variation than in control conditions on the ground; activities of trapezius muscle as an antigravity muscle were suppressed, and electric discharge from the muscle was small even if the head is moved; the eyeballs move in coordination with the head when viewing an object; microgravity environment showed a head motion with very little muscle discharge possible as in the case where the head is held unmoved; and difference in motion patterns between the antigravity muscles and non-antigravity muscles may exist as a possible cause of spacesickness in addition to the conventional sensory disagreement theory. 32 refs., 6 figs.

    Noise and vibration were measured in Akita City. In 1994, noise and traffic-caused vibration were measured along the trunk lines and other roads across the entire Akita City area. In 1995, the effort centered on the Ibarashima manufacturing quarters, the important source of noise and vibration in Akita city. The general-purpose noise meter LA-220S was used to measure noise and the vibration level meter VR-5100 was used to measure vibration. The results of noise measurement carried out at 122 points in Akita City indicated that the noise level was high along Route 7, Route 13, and the southern line belonging to the newly built national highway, marking the highest of approximately 74dB. As compared with the measurement made in 1968, the value was higher by 3-13dB. A roughly similar trend was seen in vibration. The noise level measurement of 1995 accomplished at 100 points in the vicinity of Ibarashima district indicated that the factories were responsible for high levels of noise and vibration. It was found that the levels lowered in proportion to the increase in the distance from the factories. 11 figs., 1 tab.

    An examination was made on the possibility of data processing by stacking with scattered waves assumed in a seismic exploration analysis (diffraction stacking method). In the examination, a CDP stacking method and the diffraction stacking method were compared through numerical experiments in the case of imaging a flat reflection surface and an irregular reflection surface. As a result, it was revealed that the CDP stacking method for stacking mirror reflection waves was merely a processing to raise S/N ratio while the diffraction stacking method for stacking with scattered waves assumed contained a migrational aspect as well as an aspect to raise S/N ratio. Consequently, it was shown that, if an oscillator was properly arranged, a structural imaging was possible not by the shape of a reflection surface but by the diffraction stacking method. Additionally, the diffraction stacking method revealed that the imaging effect varied by frequency with the stacking effect decreased at high frequencies, and that no stacking effect decreased at low frequencies but resolution lowered in horizontal direction. 4 refs., 8 figs.

    In a high-rising building, a group control system is indispensable which controls elevators systematically in order to improve efficiency of transportation. The group control and supervision are divided into two kinds namely the allocated control and the operation control. The former is the control to determine the optimal elevator which is to respond to a call of an individual passenger and the latter is the control to determine the operational practice as an elevator group in response to changes of the macroscopic traffic flows which are repeated periodically like morning rush hours or a lunch time. In this article, the meaning of the operation during morning rush hours has been discussed, the effect of the operation during the rush hours has been verified through simulation, and as a result, it has been verified that the determination of number of elevator cages to be arranged by the number of passengers (in particular the number of passengers from the main floor) is not necessarily related to improvement of total transportation efficiency. Besides, after analyzing the behavior of the group of elevators under the morning rush hour operation, the new index for determination of the optimal number of elevator cages at the main floor has been established, a new practice for determining the number of cages to be arranged based on the above has been proposed, and its effect has been verified. 7 refs., 10 figs.

    A large offroad unmanned dump truck navigation system has been developed, and is in practical operation mounted on dump trucks at Torigatayama Limestone Quarry of Nittetsu Mining Company. The system functions in a manual dump truck navigation mode, wireless navigation mode, and unmanned control mode. The unmanned control mode further includes a mode to navigate the truck on a predetermined course with its data having been input in a computer and a mode that when the truck was moved on a course under a wireless control, the computer learns the course and drives the truck autonomously thereafter. The safety measures are divided into the hardware safety function to detect abnormalities in brakes and other vehicle parts, and the software safety functions of data communications, sensor action check, and prevention of collision of trucks with each other. The system has resulted in a productivity of average one-way travel distance of 345 m, and average unmanned navigation cycle time of 9 minutes and 26 seconds for a transportation efficiency of 541 t/hour/truck, having reached at least the manned operation level. 4 figs., 1 tab.

    In column footing or semi-submergible type marine structures, a vertical wave force vanishes at a specific period of waves. This phenomenon is called wave-free characteristics. This wave-free characteristics make it possible to design marine structures superior in oscillation performance in waves. Since Bessho`s wave-free theory is useful only for an infinite water depth, this paper studied the wave-free theory for a shallow sea area. On a wave-free singularity and required floating body form, 2-D and 3-D axisymmetric floating body forms were determined, and vertical wave force characteristics of the obtained body forms were calculated and verified experimentally. Since the source term of the wave-free singularity was weaker in a shallow sea area than an infinite deep water area, resulting in the narrow width of the obtained wave-free body forms in a shallow sea area. The wave-free theory for a shallow sea area was verified by both numerical calculation based on a singularity distribution method and model experiment for these floating body forms. 3 refs., 10 figs.

    Dielectric constants and conductivity of several volcanic and plutonic rock specimens are measured and their dielectric characteristics and water contents are examined for the purpose of achieving a high-accuracy evaluation of the result of electromagnetic wave tomography conducted in situ. A total of 13 kinds of igneous rocks are examined, the volcanic rocks including andesite, basalt, and rhyolite and the plutonic rocks including granite and granodiorite. The specimens are caused to get wet and to be dried up, their resistance and static capacity are measured, and their dielectric constants and conductivity are determined. It is found that the dielectric constant increases upon addition of water and the rate of increase is greatly influenced by porosity, that conductivity increases upon addition of water and the rate of increase is much higher than that of the dielectric constant, and that the impact of added water on the electromagnetic wave propagation velocity and damping coefficient as calculated from actually measured dielectric constant and conductivity is greater on the damping coefficient than on the electromagnetic wave propagation velocity. 6 refs., 10 figs., 1 tab.

    Inside the jet engine, the propulsion engine for an aircraft, a high speed air current is flowing, and the rotors such as the fan, compress or, turbine and so forth are rotating with a high speed in its flowing current. The flow itself in which a high speed exhaust jet is discharged in the air from engine exhaust port, and the aerodynamic noise generated by an interaction of the flow with the material bodies are the main noise sources of the aircraft engine. Because the supersonic planes are necessary to fly with mach number 2 - 3 during cruising, the turbojet engine with a large jet exhaust speed or the low bypass ratio turbofan engine is selected. Since a noise reduction by reducing the jet exhaust speed, which was an effective measure for the high subsonic speed passenger plane, can not be applied, a reduction of the supersonic jet noise, which is hard to be reduced, becomes a necessity. In addition, in recent years, a research and development of the advanced turbo prop (ATP) aircraft with a further higher thrust efficiency are advanced as well. The aerodynamical noise reduction technologies of these engines for supersonic airplanes are summarized. 14 refs., 11 figs., 1 tab.

    The paper stated a development of a hybrid car which is a parallel type with gasoline engine and electric motor as driving source (connecting each according to the situation) and is also equipped with solar cells. Specifications are gasoline engine of 1200cc, induction motor of 5.5kW, lead battery of 288V and 7.2kWh, monocrystal silicon solar cells of 180W maximum output, and body weight of 1100kg. The rear wheel is driven by electric motor, and the front wheel by gasoline engine. The car is loaded with battery charge use solar cells on hood and roof. To enhance cleaning degree, 1.6kW solar cells are installed as an installed power system and used for battery charge. Even by an electric motor with output less than that of the usual electric car, harmful exhaust gas emitted in start-up can be controlled. This is because the electric motor can be used in accelerating. It was confirmed that the power required for it could be supplied by solar cells installed on the car. The hybrid car is practically useful for prevention of local air pollution. 5 refs., 4 figs., 2 tabs.

    This paper describes simulation results of strong acceleration motion with varying uncertain fault parameters mainly for a fault model of Hyogo-ken Nanbu earthquake. For the analysis, based on the fault parameters, the strong acceleration motion was simulated using the radiation patterns and the breaking time difference of composite faults as parameters. A statistic waveform composition method was used for the simulation. For the theoretical radiation patterns, directivity was emphasized which depended on the strike of faults, and the maximum acceleration was more than 220 gal. While, for the homogeneous radiation patterns, the maximum accelerations were isotopically distributed around the fault as a center. For variations in the maximum acceleration and the predominant frequency due to the breaking time difference of three faults, the response spectral value of maximum/minimum was about 1.7 times. From the viewpoint of seismic disaster prevention, underground structures including potential faults and non-arranging properties can be grasped using this simulation. Significance of the prediction of strong acceleration motion was also provided through this simulation using uncertain factors, such as breaking time of composite faults, as parameters. 4 refs., 4 figs., 1 tab.

    Based on an investigation on the current status of member sorting and on analysis on restrictions to automation of the ship shell process, this paper describes a basic plan for a system to automate sorting works for members. The system is intended for power saving in new fields, improvement in safety and hygiene, and prevention of errors in member sorting. The automation is intended on small bones that are large in number and tend to cause errors in sorting. The area of an elbow plate of 2,000 mm {times} 800 mm thought to be small bones of the largest class is 0.80 m{sup 2}, and the weight of the small bones is made almost constant at 80 kgf. Therefore, a robot working as a major component is selected from models that have a capability of carrying a weight of 100 kgf and are capable of numerical control. A robot body is mounted on a moving trolley to sort out members cut out from steel sheets. Because the data to operate the robot can be created automatically from the data base, sorting errors due to human mistakes decrease. Amount of the member finding and handling works also decrease in the assembly process. 4 figs.

    The differential global positioning system (DGPS) can eliminate most of errors in ship velocity measurement by GPS positioning alone. Through two rounds of marine observations by towing an observation robot in summer 1995, the authors attempted high-accuracy measurement of ship velocities by DGPS, and also carried out both positioning by GPS alone and measurement using the bottom track of ADCP (acoustic Doppler current profiler). In this paper, the results obtained by these measurement methods were examined through comparison among them, and the accuracy of the measured ship velocities was considered. In DGPS measurement, both translocation method and interference positioning method were used. ADCP mounted on the observation robot allowed measurement of the velocity of current meter itself by its bottom track in shallow sea areas less than 350m. As the result of these marine observations, it was confirmed that the accuracy equivalent to that of direct measurement by bottom track is possible to be obtained by DGPS. 3 refs., 5 figs., 1 tab.

    Coal seam gas is also called coal bed methane gas, indicating the gas existing in coal beds. The gas is distinguished from the oil field based gas, and also called non-conventional type gas. Its confirmed reserve is estimated to be 24 trillion m {sup 3}, with the trend of its development seen worldwide as utilization of unused resource. For the necessity of cultivating relevant technologies in Japan, this paper considers processes of production, movement, stockpiling, and accumulation of the gas. Its productibility is controlled by thickness of a coal bed, degree of coalification, gas content, permeability, groundwater flow, and deposition structure. Gas generation potential is evaluated by existing conditions of coal and degree of coalification, and methane production by biological origin and thermal origin. Economically viable methane gas is mainly of the latter origin. Evaluating gas reserve potential requires identification of the whole mechanism of adsorption, accumulation and movement of methane gas. The gas is expected of effect on environmental aspects in addition to availability as utilization of unused energy. 5 figs.

    Presented herein are new energy-saving type products by pneumatic manufacturers. The pneumatic slide rule was developed in 1974, when the whirlwind of energy-saving as a result of the oil crisis raved all over the industries. The word energy-saving for pneumatic systems is changed into the word air-saving, which is more straightforward and directly related to saved money, and the slide rule exhibits its ability as a diagnostic tool for air-saving without adversely affecting the system functions. Noting that output required by clamping, calking and conveyance as typical works for a double acting cylinder is generated only by the forward stroke, the PFC valve was developed, in which the return stroke is set at a minimum indispensable pressure. This reduces air consumption by 20 to 30%. The other products developed include energy-saving lifter and economy valve. A new cylinder driving method was developed to reduce air consumption. The system concept of the right pressure in the right place was proposed to provide a local compressor in a production line of low pressure and high capacity. It is necessary to develop in the future an index which allows direct comparison of an energy-saving system with other driving systems. 5 refs., 14 figs.

    Measures for leveling the electric loads relying upon two facets - tariff system and business activities - in Chubu Electric Power Co., Inc. are presented. Firstly, the existing pricing systems for midnight electric power and electric light according to the period of time for the household as well as those of seasonal and time zone electric power, modifiable contract with the time zone and so forth for large industry users, together with a similar contract for the owner of regenerating installation are outlined. In addition, a price reduction system is indicated in favor of a scheduled shutdown of large industry operations as a means of avoiding electric consumption during weekdays in summer and between 13h and 16h when large demands exist. Further, a selective contract system put in service in 1995 and the price reduction for ice regenerating air conditioning system are cited. As for business facet, 1995 is regarded as the first year of the ice regenerator for its generalization through exhibition and promotive campaign to the foods processing industry, and the application of the latent heat regenerative system to perishable foods is recommended. Moreover, installation of energy saving type automatic vending machine, so-called eco-vendor is encouraged for its merit of peak-cut and energy price lowering. Lastly, activities to extend the use of electric calorifiers and the regenerative floor heating are mentioned. 2 figs., 1 tab.

    The Hokkaido Electric Power Co., Inc., aiming to enhance power generation efficiency through power load levelling, strives to expand and substantiate its electricity billing menu and to popularize and encourage the use of levelling-oriented apparatuses and systems most of which are designed for utilizing midnight power. The billing menu has in it a snow-melting power which is cut off for load levelling during the peak demand time zone. For domestic use, a time zone-specified lighting system named Dream Eight is created, which is one of the billing systems dependent upon time zone. Introduced therein for industrial use is a demand/supply adjustment contract system. Furthermore, in compliance with the amended Electricity Business Law that came into force in 1995, efforts are under way for revising the period wherein power is to be supplied for melting snow, expanding the scope of application of the power supply system dependent upon time zone, and newly introducing a heat accumulation assisted peak adjustment contract system and an operation adjustment contract system. As for business efforts in relation to load levelling, the company proposes household electrical systems centering about 200V high-efficiency apparatuses, electric water warmer contributing to the enhancement of year-round load levelling, popularization and reinforcement of electric snow melting systems, and power utilizing technologies capable of meeting local demands raised for example by agriculture and fishery.

    This paper describes efforts of load leveling in Tohoku Electric Power Co., Inc. from the viewpoint of the rate system and business development. For the approach from the rate system, various rate menus for the peak shift have been arranged for domestic and large industry customers. To create the midnight demand, spread and expansion of electric hot water service are promoted. Consequently, the contract of midnight power has reached 914,000 kW at the end of 1995, which was 774,000 kW in 1985. To spread the ice regenerative air conditioning systems, the grant of incentive to the manufacturers and special discount of electricity rate have been conducted. These systems have been introduced in the eight places of Tohoku Electric Power`s business. The spread incident system has been created to introduce the automatic vending machines for beverages with the power peak cut function. Unused energy, such as exhaust heat from the non-treated sewage water and substations has been utilized as a heat supply project for city redevelopment. Multi-functional heat pump with regenerative function has been developed. This system aims at the peak shift by combining multi-functional heat pump and electric hot water service. 2 figs., 2 tabs.

    Nippon Steel Corporation has carried out an experimental study using the Yawata waste incinerator plant in order to improve combustion control of a fluidized bed combustion chamber. For controlling the forming of dioxin, combustion control is very important in addition to conventional methods. In this paper, we report two studies about improvements on combustion control. In the first study, we verified improvement on combustion control by modifying gas flow at the freeboard. The operational results of the experiments were studied using the numerical model of the combustion chamber. The modification of gas flow at freeboard was confirmed to be effective to obtain a compact design of fluidized bed combustion chamber for municipal waste. In the second, study we improved combustion control for sewage combustion with municipal waste. In burning municipal waste and sewage, it is especially required to take combustion control into careful consideration. In this experiment, we developed a new device for supplying sewage for the appropriate controlling combustion, and verified its effectiveness to combustion control and an effective reduction of dioxin.

    Entrails of fish, fowls and domestic animals are mostly incinerated at large expenses, although partly used as foods. This study is to test `possibility of vegetable cultivation with fish breeding water,` where the entrail wastes are used as baits for fish breeding, and fish excretions are used as the fertilizer for vegetable cultivation to purify water for fish breeding. The cultivation bed consists of two sections, one for fish breeding/vegetable cultivation and the other for vegetable cultivation by the normal method. Vegetable grow notably less in the former than in the latter, 54.6 to 79.5 versus 100. Spinach contains slightly higher contents of vitamins A and C by 6 and 13%, when cultivated in the former than in the latter. Quantities of total nitrogen, phosphorus and potassium as the fertilizer components in the former are 49, 49 and 1.7% of those in the latter. It is predicted, judging from growth of the vegetables, that the former gives a harvest comparable with that by the latter, when given a 6 to 13 days longer cultivation period. 3 figs., 2 tabs.

    Although a part of the entrails of fishes, birds and livestock is used for food, most of them are treated by costly combustion because of their bad odor and looking, and International Environment and Welfare Laboratory, Toyama prefecture in Japan is studying their profitable treatment. As a part of such study, possibility of hydroponic cultivation of vegetable was tested using fish breeding water including excretions of fishes and residual feeds after use of waste as feed, and the growth condition, safety and effectiveness of cultured vegetable were verified. Three-hundred and fifty viviparous Oryzias were released into a breeding water area with no controlled pH and EC (electric conductivity). For comparison a culture solution area of 6.0 in pH and 1.2ms/cm in EC was prepared. The result on cultivation of 6 kinds of vegetable in culture beds supported by circulation of these water showed that hydroponic cultivation of vegetable using fish breeding water is possible, and average growth of 68% is obtained although difference in growth for every vegetable is found. 8 figs., 5 tabs.

    A slamming load generated by interactive motions between a ship body and water face is an important load in ensuring safety of the ship. A flat plate approximation developed by Wagner is used as a two-dimensional slamming theory, but it has a drawback in handling edges of a flat plate. Therefore, an attempt was made to expand the two-dimensional Wagner`s theory to three dimensions. This paper first shows a method to calculate water face slamming of an arbitrary axisymmetric body by using circular plate approximation. The paper then proposes a method to calculate slamming pressure distribution and slamming force for the case when shape of the water contacting surface may be approximated by an elliptic shape. Expansion to the three dimensions made clear to some extent the characteristics of the three-dimensional slamming. In the case of two dimensions or a circular column for example, the water contacting area increases rapidly in the initial stage generating large slamming force. However, in the case of three dimensions, since the water contacting area expands longitudinally and laterally, the slamming force tends to increase gradually. Maximum slamming pressure was found proportional to square of moving velocity in a water contacting boundary in the case of three dimensions, and similar to stagnation pressure on a gliding plate. 12 refs., 17 figs., 1 tab.

    This paper presents the 150kW wind turbine generator erected at a site near Kurokawa dam lake of Kansai Electric Power Co. in Hyogo prefecture. This generator is composed of a horizontal-axis propeller with 3 blades of 27m in diameter and 36/27rpm, and a tower of 30m high. Harmony with the environment was also considered because of the site in a natural park area. Its demonstration test started in Oct. 1996 at annual mean wind velocity of 2m/s. Soft start was realized by controlling inrush current and preventing voltage drop in system interconnection by use of a thyristor circuit. The dual operation system was adopted of a 30kW small generator at lower wind velocity and a 150kW large one at higher velocity. Two kinds of brakes are used, and rotor revolution was reduced by air brake (blade tip spoiler). Mechanical disk brake works for the stopped rotor or emergency stopping. Even if the wind turbine was stopped by exterior factor, if no anomaly of the turbine is found, it automatically re-starts after removal of the factor. The generator is controlled from a remote control station 150km apart through NTT communication line. 6 figs., 2 tabs.

    Described herein is the method for analyzing quantity of organic carbon synthesized by chemoautotrophic bacterium. It is based on the combustion-infrared spectroscopy, which is normally adopted for quantitative analysis of organic carbon. The problems involved in the measurement of organic compounds synthesized by iron-oxidizing bacteria are noise by culture medium components, aging of gas analyzer and contamination with organic compounds from a silicon plug. The measures taken in this study against these problems include comparison of the results with a medium containing iron-oxidizing bacteria with those with a medium free of these bacteria, calibration with the standard solution for each measurement, and replacement of a silicone plug by a silicon cap. Organic carbon is measured by a TOC-5000 analyzer equipped with an automatic sample feeder ASI-5000. Biomass density is determined by the MPN method. It is confirmed that organic carbon quantity is almost in proportion to biomass density, a phenomenon which can be used to determine organic carbon quantity. 7 refs., 6 figs., 1 tab.

    This paper investigates Momoyama hydraulic power station built on the middle reaches of the Kiso River in Uematsu-cho, Kiso-gun, Nagano Prefecture in Japan, in 1923 by relating to the feature of the building of the hydraulic power station and the architect, Shiro Sato. The hydraulic power station originally was a functional and industrial building which puts a priority on the efficiency of business economy, at the same time it was often required to present a beautiful appearance. The building of Momoyama hydraulic power station was founded on the crane girder structure covered with reinforced concrete(RC) walls. A Hat roof of RC slab was applied to the roof of the building. It was generally designed in Neo-Gothic style. More specifically, however, the wall surface was designed in church style and the upper part was like a castle in the middle ages. Therefore the total design was eclectic. The outer surfaces of the building were remained to be bare concrete as cast. Such a multiple building symbolizes the situation of Japanes architecture in the 1920s. 4 figs.

    A slamming load generated by interactive motions between a ship body and water face is an important load in ensuring safety of the ship. A flat plate approximation developed by Wagner is used as a two-dimensional slamming theory, but it has a drawback in handling edges of a flat plate. Therefore, an attempt was made to expand the two-dimensional Wagner`s theory to three dimensions. This paper first shows a method to calculate water face slamming of an arbitrary axisymmetric body by using circular plate approximation. The paper then proposes a method to calculate slamming pressure distribution and slamming force for the case when shape of the water contacting surface may be approximated by an elliptic shape. Expansion to the three dimensions made clear to some extent the characteristics of the three-dimensional slamming. In the case of two dimensions or a circular column for example, the water contacting area increases rapidly in the initial stage generating large slamming force. However, in the case of three dimensions, since the water contacting area expands longitudinally and laterally, the slamming force tends to increase gradually. Maximum slamming pressure was found proportional to square of moving velocity in a water contacting boundary in the case of three dimensions, and similar to stagnation pressure on a gliding plate. 12 refs., 17 figs., 1 tab.

    For the physical modeling system of Technology Research Center, Japan National Oil Corporation, data acquisition on the ocean and ground can be simulated using models. This system can provide data for verification of the data processing and elastic wave simulation algorithm. This can also provide data for decision of experiment specifications by making a model simulating the underground structure of the given test field. The model used for the physical modeling system is a gradient multilayer model with six-layer structure. Depth migration before stacking was conducted using data obtained through two acquisition methods, i.e., up-dip acquisition and down-dip acquisition. The depth migration before stacking was performed for data obtained by up-dip acquisition in addition to the records obtained by down-dip acquisition. Consequently, a definite reflection surface was observed, which has not been observed from the processing results of down-dip acquisition data. 9 figs.

    The Physical Modeling System introduced into the Technology Research Center, Japan National Oil Corporation, and data collected by use of the system are presented. The Physical Modeling System is 10,000 times smaller than the real one, comprising a water tub section, measuring device section, and control section, etc. The water tub section comprises a tub for housing the model, transducers for transmitting and receiving vibration, controllers, etc. The water tub measures 1.8{times}1.2{times}0.9m. The model used in the experiment is an `inclined multilayer model` with each of its six layers pinching out toward the top, and is usable for the comparison of various migration methods. In one case in the records, reception was made at 184 reception points deployed at intervals of 3mm, when the minimum offset was 15mm and the maximum offset 564mm. Nothing very obvious was observed when the ordinary overlapping of DMO and CDP was applied to this record, which suggests that pre-overlapping migration treatment is required. 5 figs.

    This paper reports model experiments to evaluate flow rates of fluids passing through a fracture by using a Doppler borehole televiewer (DBHTV). A supersonic transducer disposed on a well axis transmits transmission pulses, and a transducer receives scattered waves generated by particulates in water and waves reflected on a well wall. This signal is applied with time gating to extract only the scattered waves from particulates in the vicinity of the well wall. Deriving spectra in the recorded Doppler signal obtains flow velocity components in the direction of the well radius. A model was made with a polyvinylchloride pipe with a diameter of 14.6 cm to simulate a well, to which an aluminum pipe with an inner diameter of 2 mm is connected to be used as a simulated fracture, and mud water is circulated in the pipe. The result of deriving a passed flow volume in this model by integrating flow rate distribution derived by using the above method to a predetermined range in the vicinity of the fracture showed a good proportional relationship with actual flow rate in the simulated fracture. 1 ref., 7 figs.

    Experiments have been done to investigate the transition process of the laminar separation bubble on airfoils. Measurements of the power spectrum density distribution of the streamwise velocity fluctuation was made. Three airfoils which have different steplike pressure distributions were used for measurements. A discrete spectrum and its sub and higher harmonics were observed. The frequeny of the discrete spectrum was in good agreement with that predicted by the linear stability theory of the separated free shear layer. From results, it is concluded that the velocity disturbance observed initially in the amnner separation bubble for the three airfoils shows similar characteristic to that in the separeted free shear layer. For the airfoil whose design pressure recovery is minimum among three airfoils, however, another kind of the discrete spectrum was also observed. This is interpreted to be caused by the interference with the external cyclic disturbance. 11 refs., 11 figs.

    Experiment and investigation are conducted in the Yurihara District, Akita Prefecture, to verify that the magnetotelluric (MT) method can be effectively applied to oil and gas fields. In the Yurihara district there exist a number of pits dug for exploration or production, and records on seismic surveys conducted, and therefore the geological structure of this district can be explained fairly well. The oil and gas reservoirs belong in the Nishikurosawa stratum overlain by the Onagawa stratum and Funakawa stratum. The Nishikurosawa rocks, basaltic rocks for example, present a resistivity of approximately 5 ohm/m which is higher than that of the other two that is more or less 1 ohm/m. Under the circumstances, experiment and investigation are conducted so as to detect the Nishikurosawa basaltic rocks as a high-resistivity stratum located under low-resistivity strata by use of the MT method. As the result, a high-resistivity stratum corresponding to the Nishikurosawa basaltic stratum is detected under low-resistivity strata, and the three-dimensional structure of the basaltic stratum is disclosed. In this stratum, the resistivity value gradually increases from south toward north with occasional abrupt rises, and it is found that such abrupt rises result from oil and gas producing strata where exploitation is under way. 5 refs., 6 figs.

    This paper illustrates the field experiment results in which micro-gravity survey was applied to investigation of very shallow basement structure between a few m and 10 m. Its applicability was discussed. In principle, the micro-gravity survey was conducted at the measuring points in a grid with 20 m pitch. Measuring points of 174 were used. The gravity system used for the measurements is an automatic gravimeter CG-3M made by the Scintrex. Survey results of P-wave reflection method conducted at the site using a vibrator focus were used as control data of micro-gravity survey. Consequently, change in the thickness of surface layer (earth filling) shallower than the depth of -10 m could be grasped as a plane. It was found that the micro-gravity survey is a useful method for the investigation of very shallow basement structure. Survey results by the reflection method could contribute to the determination of trend face at filtration and construction of density model as well as the geologic interpretation of gravity anomaly. As a result, reliability of micro-gravity survey and reflection method could be enhanced, mutually. 3 refs., 8 figs.

    A 3D seismic experiment was carried out in the Minaminoshiro area in Akita Prefecture, an area difficult of performing seismic exploration. This paper reports progresses during data processing and future problems. The data processing has executed static correction of 3D refraction, 3D DMO correction, and an F-X prediction filter processing on the data in time domain in the 3D seismic exploration as acquired in a spread of 4 km times 5 km in the subject area. The result of the data processing verified existence of a folding structure and the Noshiro thrust fault groups in the east to west direction, and locations of the Sakagawa fault associated therewith. Seen particularly noticeably was a structure having a slope falling north-ward at 15 to 35 degrees in shallow and deep portions on the east side of the Sakagawa fault in the south to north direction. In addition, the Dogiri fault was identified, which has been though to exist in a direction crossing perpendicularly the Noshiro thrust fault groups. It is scheduled that spatial velocity will be analyzed, and data processing will be conducted for deep regions. 7 figs.

    Collaborative research was conducted by National Aerospace Laboratory and Japan Aircraft Development Company in the period of fiscal 1988-1992 into methods for testing aircraft with advanced propeller in low-speed wind tunnel. The propulsion efficiency of the currently available high-bypass turbofan engine is approximately 60% in the vicinity of Mach number 0.85. Propeller-driven aircraft, whose propulsion efficiency is as high as 80% in the low Mach number domain, are scarcely in practical use in the domain of Mach number 0.75 or higher. There are studies reported abroad as well as in Japan for the propeller-driven aircraft to enjoy higher propeller propulsion efficiency even in the vicinity of Mach number 0.8 by modifying the propeller diameter, number of blades, and blade sections, etc. This paper describes the experimental research into the high-speed counter-rotation propeller. A counter-rotation propeller 0.3m in diameter and provided with coaxially arranged 8times2 SR-2 blades is evaluated for pitch angles during the takeoff and landing modes, for thrust characteristics at the pitch angle for the cruising mode, and for propeller backwash and noise. 15 refs., 72 figs., 9 tabs.

    Tyre/road interface noise can be amplified by a horn type space formed by the tread face of the tyre and the road. This paper is a report on studies on experiment and computation to elucidate the above phenomenon in detail. Measurement and computation were carried out on a tyre replaced with a single cylinder, whereas it was verified that the horn effect by each frequency can be calculated by BEM computation. Then, discussions were given on actual tyres combined with the BEM computation, and the following results were acquired: (1) the horn effect is small in zones of low frequencies; (2) the larger the tread width, the larger the horn effect increases; (3) the relationship between the tread width and the horn effect is governed by the ratio of the road contact width to noise wavelength; (4) the frequency characteristics of the horn effect vary largely according to whether the sound source exists in forward or rearward locations; (5) the relationship between the forward and rearward locations of the sound source with the horn effect is governed by the distance between the front and rear ends of the road contact face of the tyre; (6) the smaller the radius of the tread shoulder, the greater the horn effect; (7) tread deformation due to load applied on the tyre slightly changes the frequency characteristics of the horn effect; (8) with the sound source existing closer to the center of ground contacting width, the horn effect increases; and (9) the present study has verified the horn effect of 22 dB as the maximum. If the sound source is not present at the center of ground contacting width, the horn effect is reduced to about 10 dB, but the value cannot be ignored as the influence on traffic noise.

    Temperature and humidity characteristics and condensation within walls under heating and humidification were studied experimentally in winter using two test houses of conventional and ventilated structures. The absolute humidity in conventional one fluctuated depending on temperature gradient, water flux due to humidification and water adsorption onto glass wool, and accumulated water increased with humidification. That in ventilated one was also affected by dehumidification through ventilation layers. Under heating and humidification, the absolute humidity increased depending on temperature rise and water flux within walls. In conventional one, condensation was frequently observed on felt in walls and others because of accumulated humidity, while in ventilated one, humidity was kept lower within walls even under heating, because humidity in walls was discharged through ventilation layers. Condensation was also scarcely observed on waterproof moisture-permeable sheets in walls and others. 3 refs ., 39 figs 1., tab.

    Vacuum brake booster has been widely applied in automobiles, and it needs much time for experiments in order to design a new type model and so on. In this report concentrating on the behavior of a reaction disc, it was simulated by ARAQUS FEM program where coefficients of rubber disc are Mooney-Rivlin constants. It was shown that the numerical results represent good agreement with experiments, and in addition that values of jumping force which shows the starting point of the brake increases with the increment of the hardness of the disc, clearance and so on. 2 refs., 10 figs.

    Model simulation technology is important for automobiles development. Especially, for the investigations concerning to ABS, TRC, VDC, and so on, the model should be the one which can simulates not only whole behaviors of the automobile, but also such internal information as torque, acceleration, and, velocity of each drive shafts, etc.. From this point of view, 4-wheels simulation model which can simulates almost over 50 items, was made. On the other hand, technique of 3-D image processing using 2 video cameras was adopted to identify the model. Considerably good coincidences were recognized between the simulated values and measured ones. 3 refs., 7 figs., 2 tabs.

    Laboratory experiment on sandy soil and weathered rock was conducted to clarify the generation mechanism of streaming potential due to underground fluid. Streaming potential is caused by underground fluid flow, namely by fluid flow in porous substances as electrokinetic phenomenon. In experiment, Inagi sand, Toyoura sand and strongly decomposed weathered granite were used. In Inagi and Toyoura sands, positive streaming potential was observed downstream in fluid flow. Streaming potential could be nearly determined as primary function of fluid velocity, and generated streaming potential increased with fluid resistivity. Streaming potential was higher in Inagi sand than Toyoura sand, probably depending on hydraulic radius, size of bleeding channel, and conductivity of sand surface. In weathered granite, negative streaming potential was measured. In the case of positive {zeta} potential, negative streaming potential is theoretically generated downstream in fluid flow. This experiment suggested possible generation of negative streaming potential in some kinds of ground. 2 refs., 6 figs., 1 tab.

    In order to utilize more effectively wide oceanic spaces, a feasibility study is performed on submerged large shell structures from the aspect of structural engineerings. As part of the study, for the purpose of deriving dynamic response characteristics of a structure, development was made on a numerical analysis code, `DASOR`, required to analyze natural frequency of a rotating shell fixed in water. The `DASOR` is a dynamic analysis code to derive added water mass effect, and effects of water depth on the dynamic response characteristics based on the shell theory by Donnell-Mushtari-Vlasov. This paper describes an experiment using a cylindrical shell to elucidate effects of the cylindrical shell on vibration characteristics due to contact with water. Comparisons and discussions were given on the result of numerical calculation using the `DASOR`, solution of a simplified theory analysis, and the result of the experiment to make clear the reasonability of the `DASOR`. The cylindrical shell in water has its natural frequency decreased due to the added water mass effect in association with increase in the water level. The `DASOR` showed good agreement with the experimental values as a result of giving considerations on the boundary conditions, by which its reasonability was verified. 3 refs., 9 figs., 2 tabs.

    To investigate a possibility of exploration of underground water flow as well as to grasp the underground fluid flow by measuring streaming potential at the ground surface, some experiments were conducted using a model unit by considering the difference of permeability. For this experimental unit, water is driven by adding head difference between the polyethylene vessel filled with water and the experimental water tank. The size of water tank is 350{times}160 mm with a height of 160 mm. Twenty platinum electrodes are set on the cover of water tank. Toyoura standard sand and Kanto loam were used for the experiments. For the experiments, fluid was injected in various combined models by considering the permeability, to measure the streaming potential. As a result, it was explained by the streaming potential that the fluid flows in a form of laminar flow in the experimental water tank, and that the movement of fluid in the Kanto loam is quite slow. It was also confirmed that the streaming potential method is an effective technique for grasping the movement of fluid. 3 refs., 8 figs.

    CO2 laser beam has been applied to cut of the aluminum alloy. Average cut width, roughness of cut surface and average thickness of heat affected zone are investigated as functions of laser power, cutting speed and assist gas pressure. The average cut width increases with laser power, but it does not depend on the cutting speed. The narrowest average cut width obtained is 0.22mm under the conditions of laser power of 900W and cutting speeds from 600 to 1000mm/min. The roughness of cut surface decreases with decreasing cutting speed. The best smoothness of cut surface obtained is 17 {mu}m (Rmax) , when the conditions are 1100W and 600mm/min. The average thickness of heat affected zone decreases with increasing assist gas pressure. CO2 laser beam cutting is applicable to flash removal from aluminum alloy casting. This process is expected to reduce the need of physical labor and to improve the working conditions in the foundry industry. 32 refs., 10 figs., 2 tabs.

    The underground radar exploration is adopted to surveys of cavity under the road and buried pipes since the result of high resolution is obtained. However, the explorative depth of the radar is shallow, 2-3m in soil basement, and its applicable field has been limited. The continuous wave radar (FM-CW radar) was devised to get deeper explorative depth, but has been used for the geological structure survey such as the fault survey since it is lower in resolution as compared with the pulse radar. Therefore, to make use of characteristics of the continuous wave radar and enhance resolution in the shallow part, an experiment on buried pipes was conducted for the purpose of assessing and improving the FM-CW radar. In this processing, the wave form treatment used in the reflection method seismic survey was adopted for the radar survey. There are some problems, but it is effective to adopt the same algorithm to that used in the seismic survey to the radar exploration. The explorative depth was discussed from the damping rate of electromagnetic waves and dynamic range of facilities of the experimental site, and 7m was obtained. 5 figs., 1 tab.

    This paper reports a predictive result on a deformation experiment on sand beds using an X-ray computerized tomography (CT) equipment. The X-ray CT is a method to perform the following processes: X-rays are irradiated on a sample; decayed intensity data are measured along ray paths of the permeated X-rays; the data are inverted by using the Fourier transform; and spatial distribution of the coefficient of X-ray absorption inside the sample is acquired as a gray scale image. The deformation experiment was carried by putting sand into an acrylic container to a depth of 2 cm and manually pressing a plate in the horizontal direction. Sand blocks make a relative motion along a specific plane when they are deformed, but it was not possible to recognize faults clearly by naked eyes. Upon completion of the deformation, the experimental device was placed on the CT equipment to acquire images of the two-dimensional cross section. The higher the X-ray absorption coefficient, the brighter the picture elements. It can be seen that three inversed faults have been imaged clearly. Therefore, this equipment was verified usable as an effective observation equipment for an analogue deformation experiment. 4 refs., 2 figs.

    Practical application of subsurface crack characterization by the borehole radar measurement to which the radar polarimetric method was introduced was attempted to measuring objects for which the borehole radar has not been much used, for example, the inside of low loss rock mass or fracture zone where cracks tightly exist. A system was trially manufactured which makes the radar polarimetric measurement possible in the borehole at a 1000m depth and with a about 10cm diameter, and a field experiment was conducted for realizing the subsurface crack characterization near the Nojima fault. For the measuring experiment by the polarimetric borehole radar, used were Iwaya borehole and Hirabayashi borehole drilled in the north of Awaji-shima, Hyogo-ken. In a comparison of both polarization systems of Hirabayashi borehole, reflected waves at depths of 1038m and 1047m are relatively stronger in both polarization systems than those with the same polarization form and at different depths, whereas reflected waves around a 1017m depth are strong only as to the parallel polarization system. Characteristics of the polarization in this experiment indirectly reflect crack structures. 6 refs., 6 figs., 1 tab.

    With the purpose of converting solar heat energy to industrial heat energy, an experiment of acetone hydrogenation was carried out using a heat exchanger type reactor that recovers heat generated by acetone hydrogenation, an exothermic reaction, and supplies it to an outside load. In the experiment, a pellet-like activated carbon-supported ruthenium catalyst was used for the acetone hydrogenation with hydrogen and acetone supplied to the catalyst layer at a space velocity of 400-1,200 or so. In the external pipe of the double-pipe type reactor, a heating medium oil was circulated in parallel with the flow of the reactant, with the heat of reaction recovered that was generated from the acetone hydrogenation. In this experiment, an 1wt%Ru/C catalyst and a 5wt%Ru/C catalyst were used so as to examine the effects of variation in the space velocity. As a result, from the viewpoint of recovering the heat of reaction, it was found desirable to increase the reaction speed by raising catalytic density and also to supply the reactant downstream inside the reaction pipe by increasing the space velocity. 1 ref., 6 figs., 1 tab.

    In order to predict the three-dimensional response to vortex-induced oscillation of bridges, a model was investigated using the aerodynamic force coefficient including vortex-induced and self-excited forces, and the nonlinear response coefficient expressing constancy of response to vortex-induced oscillation. In the analysis, change of frequency in wind by the self-excited force, aerodynamic damping term, effect of the mode, and correlation of the vortex-induced force along member axis were taken into account. The aerodynamic force and nonlinear response coefficients were identified from the homogeneous and turbulent flow results of wind tunnel tests using a two-dimensional spring support rigid body model with varied damping factor. The aerodynamic damping term can be estimated from the nonlinear aerodynamic force coefficient, but it was enough to calculate it from the quasi-stationary coefficient in general bridge profiles. The correlation of the vortex-induced force was obtained from measurements of the vertical variation components of trailing flow under the resonance state, or the pressure distribution of the member surface. When comparing to the wind tunnel test of three-dimensional model of cable-stayed bridge, the response amplitude by the present analysis method was consistent well with the test results rather than by the method in which the amplitude of two-dimensional model was corrected. 10 refs., 4 figs., 3 tabs.

    Long-span cable-stayed bridge requires indispensably discussions on safety against gale and earthquake, and correct assessment on its inherent vibration characteristics at the design stage is critical. However, theoretical assessment on structural decay is difficult, hence it is desirable to make measurement and verification upon its completion. This paper reports the result of measurements and considerations on a three-span continuous steel cable-stayed bridge with a length of 790 m (185 m + 420 m + 185 m) spanning between Hitsuishi Island and Iwakuro Island in the Kojima-Sakaide route of the Honshu-Shikoku connecting bridge. Large shaking machines were used to give girders vibrations with large amplitudes (10 cm at maximum), and high-accuracy measurements were made. The measurements verified the reasonability of the dynamic design for the bridge. The measured value of the logarithmic decay rate [delta] as the major experimental data presented that bending vibration is large as a whole, with torsional vibration somewhat smaller, and all the design values were on safety side. Confirmation was made on amplitude dependence of the decay rate, the inherent modes of low-order vibrations, and coupled behaviors among the girders, cables, and towers. 16 refs., 13 figs., 3 tabs.

    Field vibration test of the Tsurumi Tsubasa Bridge, a long span cable stayed bridge, has been conducted. Focusing on its dynamic characteristics, an identification method from test results and its validity were investigated. The natural frequency identified using mode circle and resonance curve from steady vibration test agreed with that identified by the peak method from free damping test. Accordingly, there was no difference due to identification methods, and both methods provided appropriate accuracy. The natural vibration mode obtained from the steady vibration test agreed with that obtained by the eigenvalue analysis. The dispersion of experimental values, which indicates the adaptation to mode circle method, became a scale indicating reliability of identified values. When the damping obtained by the half power method for the microtremors test is compared with that identified from the steady vibration test and free damping test, it is required to compare them at lower amplitude level region, considering that the amplitude level of microtremors test is very low. For the dynamic characteristics of the Tsurumi Tsubasa Bridge, it was found that it has lower natural frequency and higher modal damping compared with other cable stayed bridges with similar scale of span. 18 refs., 13 figs., 4 tabs.

    Full Text Available The aim of this paper is to analyse the linguistic factors constraining the use of personal clitics lo(s, la(s, le(s in XVth Century Middle-Age Castilian, as revealed in the Relación de los Hechos de Don Miguel Lucas de Iranzo (1458. A multivariate analysis of data from this text shows that internal (morphological, syntactic, lexical and textual factors interact and allows us to imagine the simplest and original context where leísmo could start. A nearly categorical tendency to employ le for male referents as direct objects is developed with human antecedents and where Latin used dative case or alternated between dative and accusative case. If Latin used accusative case, occurrence of le (leísmo depends on a set of linguistic constraints whose effect is systematic and predictable, as shows a logistic regression analysis carried out in this paper. Use of le (leísmo for human antecedents is constrained by the following internal factors: etymology, the number and the clitic's position within the sentence, type of syntactic structure and the verb's tense.

    An investigation was given on the relationship between methanol adsorbing behavior of reformed coal surface and oxygen containing functional groups in coal. Akabira bituminous coal was air-oxidized or Yallourn brown coal was decarbonated in oil as a reformation treatment. Both of the treated and untreated coals showed an adsorption heat curve of the Langmuir type. The Akabira coal had its oxygen content and the adsorption heat increased as a result of the air oxidizing reformation treatment. The Yallourn coal had its oxygen content and adsorption heat decreased as a result decarbonation reformation treatment. Oxygen containing functional groups act as strong adsorption sites for methanol, and the maximum adsorption amount depends on oxygen content in the coals. Since the coal surface is non-uniform in terms of energy, methanol is adsorbed first into sites with higher molar adsorption heat, and then into lower sites sequentially. Therefore, distribution of the molar adsorption heat can be derived from the relationship between adsorption amount and adsorption heat by changing methanol adsorption amount. The distribution of molar adsorption heat becomes broader when the oxygen content is high, and narrower when low. 2 refs., 2 figs.

    Interaction between carbon blacks and oxygen molecules has been studied by means of electron spin resonance (ESR) spectroscopy. The ESR spectra of the carbon blacks appears at the g-value of free spin, which are contributed by both isolated electrons and conduction electrons. Upon introducing oxygen to the system the ESR linewidth was broadened in proportion to the partial pressure of oxygen. In case of lampblack (LB 101, Degussa) the interaction was not so strong that it took a tong time at 77K for the linewidth to reach the maxmum value. In case of gassblack (P 140 V, Degussa), on the other hand, the oxygen was easily adsorbed at 298K and the linewidth at 77K became its maximum immediately after cooling. The number of unpaired electrons decreased when the system was kept at 298 K and the decrease was prominent for the local spins. These phenomena have been explained with a simple band model for the electron. (author)

    Full Text Available Setting priorities in the conservation of terrestrial ecosystems refers to the need for knowledge about the diversity of environments, especially in the Cerrado biome and its floristic transition zones, already in high stage of degradation. With this scenario, t his study aimed to carry out a floristic inventory of a forest fragment on ecological tension in Bodoquena Plateau, MS, Brazil, and assess their phytogeographical relationships with other surveys of seasonal forests and savannas in the Midwest and Southeast regions of Brazil. For this, 102 contiguous plots of 10x10 m (100 m 2 were sampled. The inclusion criterion was the perimeter at breast height (PBH ≥ 15 cm. For floristic similarity analysis, the coefficient of Sorensen was applied, adopting the unweighted pair group method with arithmetic mean (UPGMA, with the determination of the level of similarity of 26 floristic lists. Of the 96 species occurring in this survey, 91 were identified at species level, and of these, 80.2% (73 were found in one or more studies of the analyzed areas with higher occurrence in seasonal deciduous forest (SDF (54, followed by seasonal semideciduous forest (SSF (47 and forested savannah (46. The results showed clustering of the study area with the FED of Minas Gerais in level of 30%, revealing low similarity. Due to low floristic similarity between the analyzed areas, these are characterized by their high beta diversity.

    This paper introduces Chubetsu Dam planned with a large-scale embankment having a river bed width of 600 m. Chubetsu Dam is being constructed with such objectives as flood control of Ishikari River, river flow rate maintenance, drinking water supply, irrigation water supply and power generation. The dam site is a gravel bed having a river bed width of 600 m and a maximum foundation rock thickness of 40 m, requiring evaluations as a dam foundation and discussions of water shielding methods. As a result of discussions at the Chubetsu Dam technical discussion committee, the dam type is decided to be a composition dam consisting of a gravity type concrete dam on the left river side and a central core type fill dam using a part of the gravel bed as the foundation on the right river side. A continuous underground wall system is planned to be used for shielding water in the gravel foundation. In discussing the anti-seismic properties, analyses for bank construction and water filling to derive stress and deformation conditions prior to an earthquake and a time-history response analysis to derive conditional changes during the earthquake are performed. According to the results thereof, evaluations are given on the safety by compounding the stress and the acceleration. In plans to improve the surrounding areas, an area will be provided upstream the reservoir where the water level is kept constant to serve as a bird sanctuary. 7 figs.

    On the insert reinforcing bar structure for the connecting part of the main tower of cable stayed bridges, this paper reports verification results on a load resistant safety with a full-scale model, structure analysis and construction work. The basic structure was composed of a drilled steel shell, inserted reinforcing bars, fixing structure of bars in lining concrete of the shell and a pressure bearing plate. As an experimental result, the connecting part had a sufficient load carrying capacity against both tensile and compressive loads. The shear stress of the insert reinforcing bar structure was estimated successfully under von Mises`s condition. The shear spring constant in deformation characteristics was linearly proportional to an inserted reinforcing bar ratio. In earthquake, nearly 60% of an allowable compressive load was transferred to concrete through the pressure bearing plate. The analytical results of load resistant deformation characteristics of the connecting part well agreed with experimental ones, and the proposed analytical model was applicable to estimation of a dynamic behavior. 5 refs., 22 figs., 4 tabs.

    The load leveling method of batteries for electric vehicles was studied for extension of a battery life and mileage every charging. Under large load fluctuation conditions such as deceleration and acceleration, use of electric power sources other than battery for peek load at acceleration can improve a battery life, output power capacity and mileage every charging. Combination of effective recovery of regenerative power at deceleration with its discharge at acceleration is one of the effective methods. The electric double layer capacitors are serially connected with the batteries, regenerative power is charged only into the capacitors, and both voltages of the battery and capacitor are applied to a power circuit. Battery load is reduced by load on the capacitor. Until the capacitor is re-charged by regenerative power after full discharge, power is supplied only by battery through a diode. Capacitor power is used as effectively as possible until approaching considerably low voltage. As peak load of the battery is reduced by 30%, the mileage increases by 5.7%, and the battery cycle life becomes 1.5 times longer. 7 refs., 5 figs., 3 tabs.

    Influence of pseudo-random geometry on the imaging for 3D seismic exploration data acquisition has been investigate using a simple model by comparing with the regular geometry. When constituting wave front by the interference of elemental waves, pseudo-random geometry data did not always provide good results. In the case of a point diffractor, the imaging operation, where the constituted wave front was returned to the point diffractor by the interference of elemental waves for the spatial alias records, did not always give clear images. In the case of multi point diffractor, good images were obtained with less noise generation in spite of alias records. There are a lot of diffractors in the actual geological structures, which corresponds to the case of multi point diffractors. Finally, better images could be obtained by inputting records acquired using the pseudo-random geometry rather than by inputting spatial alias records acquired using the regular geometry. 7 refs., 6 figs.

    The matching of the wind turbine type and system scale of the stand-alone wind turbine generator system to wind conditions is investigated using our dynamic simulation model. This paper examines three types of wind turbines: the Darrieus-Savonius hybrid wind turbine, the Darrieus turbine proper and the up-wind Propeller turbine. These systems are mainly operated at a constant tip speed ratio, which refers to a maximum power coefficient. As a computed result of the net extracting energy under fluctuations of wind speed and direction, the Darrieus turbine proper has little conformability to wind fluctuations because of its output characteristics. As for other wind turbines, large-scale systems do not always have advantages over small-scale systems as the effect of the dynamic characteristics. Furthermore, it is confirmed that the net extracting power of the Propeller turbine under wind direction fluctuations is much reduced when compared with that of the hybrid wind turbine. Thus, it is concluded that the appropriate wind turbine type and system scale exist for each wind condition. (author)

    Imagining a space in the middle of the 21st century, a space station installed with the artificial gravity generation facility is constructed, and a space factory utilizing a gravity free environment is also constructed. The construction materials for the space structures of this kind are prepared from the resources of the Luna. A solar power generation satellite being arranged with the solar cells manufactured from a silicon of the Luna is allocated on a geostationary orbit, and a power generated is supplied to the earth by the microwave. In such a time, a regular liner to the Luna and a ferry boat to the Mars will have come to fly, and furthermore an oxygen used for the propellant to them as well will be supplied from the Luna. In order to realize such a conception, there are various problems to be overcome such as a transportation problem first of all, a long life problem in the Luna and Mars bases and so forth. Furthermore a consideration to the environmental conservation of the Luna and Mars is also required. The nature of the Luna without a crustal alteration, meteorological phenomena, and organisms has no force to restore an environmental destruction. As for a space development in the future, it is desired that it should not damage a nature of the space and should be a field to chase a possibility of the human beings for a long time. 30 refs., 14 figs., 1 tab.

    A PTSP simulator, developed by combining a fluid flow simulator and a simulator for computing the spontaneous potential (SP) out of flow velocity distribution, was used to investigate the impact of the distribution of terrain, permeability, and resistivity upon the ground surface SP. SP computation using simple models such as highlands or cliffs indicated that the terrain-caused SP anomaly was negatively dependent upon elevation. It was also indicated, however, that, in some types of resistivity distribution, the SP profile changes, the peak goes out of place, and even the apparent polarity may reverse in extreme cases. In the study of the SP profile for the Takeyu hot spa, Oita Prefecture, PTSP-aided modeling was carried out. It was then found that fluid flows caused by the terrain were not enough to explain the peak at the middle of the mountain, which suggested the existence of a fluid flow caused by temperature distribution. 11 refs., 5 figs.

    This paper reports pressure response analysis on wells piercing a high angle multi (HAM) fracture model. In this model which is defined on a three-dimensional space, a plurality of slanted fractures intersect with wells at high angles (however, intersection of fractures with each other is not considered). With respect to the pressure response analysis method using this model, the paper presents a basic differential equation on pressure drawdown and boundary conditions in the wells taking flows in the fractures pseudo-linear, as well as external boundary conditions in calculation regions (a reservoir spreads to an infinite distance, and its top and bottom are closed by non-water permeating beds). The paper also indicates that results of calculating a single vertical fracture model and a slanted fracture model by using a numerical computation program (MULFRAC) based on the above equations agree well respectively with the existing calculation results (calculations performed by Erlougher and Cinco et al). 5 refs., 6 figs.

    This paper reports a rapid change in the drift of a sea-gravity meter SL-2 after 1987 and after its modification in 1993. In order to confirm the accuracy of the sea-gravity meter of the Hakurei-maru, changes in the lapse of time were summarized on the relative gravity value at the Funabashi base and on the drift rate in each voyage. The drift rates in the case of departing from and returning to Funabashi base were all less than 0.1mgal/day except the first year of 1987, which was presumably due to the growing stability of the gravimeter. The drift value of 1992 was 0.05mgal/day, producing an error of only 2mgal without drift compensation at the end of a 40 day voyage. The gravimeter after the total renewal of the control part in 1993 produced a large drift in the direction opposite to the conventional drift. The cause of these phenomena was supposed to be some kind of change in the spring property during the gap of one year; this large drift seemed to be settling down after the elapse of approximately one year. 4 refs., 8 figs., 2 tabs.

    Studies are made about the control of the power conditioner over the maximum power point tracking (MPPT) function in a photovoltaic power generation system. The analysis is conducted by means of computer simulation into the effect of a start/stop function added to the control of MPPT and the effect on the generation of power of the setting of parameters in the start/stop function. The reduction in output power due to difference between the actual operation point and the optimum operation point is evaluated by use of a load matching correction factor. In this simulation, it is assumed that the solar cell array consists of 13 rows in 5 parallel columns, is capable of a normal output of 3.149kW, has a panel tilted at 30 degrees, and faces due south. The power conditioner is assumed to be a system rated at 3kVA, equipped with system interconnection and back flow features. As a result, it is learned that the stop voltage should be set at 180V or lower and the steady voltage near 185.5V for a good result and that there is not much need after all for the start/stop technique. 2 refs., 8 figs., 2 tabs.

    On the hydroelastic behaviors of a huge floating structure, a mutual interaction theory based on the area division method is used for the analysis of a fluid problem and a mode analysis method is used for the analysis of deformation. On the continuous deformation of a floating structure, the structure is considered as a set of partial structures obtained when the plane shape was divided into squares and discretely handled as a series of rigid motions in the small partial structures obtained by dividing the partial structures more finely. The experimental result in a water tank and the distribution method at a singular point were compared on the deformation of the elastic floating structure estimated by calculation based on this formulation. The result showed that the estimation method on the hydroelastic problem proposed in this paper is valid. On the prediction of hydroelastic behaviors of a huge floating structure, various calculation examples indicate that the hydroelastic behavior is not only the relation between the structure length and wavelength, but also that the bending rigidity of a structure is a very important factor. For a huge floating structure in the 5,000 m class, up to shorter wavelength of about {lambda}/L = 1/100 must be investigated. 6 refs., 14 figs., 5 tabs.

    Enteric virus discharged from human being is treated together with sewage water, but the activated sludge process cannot treat it completely. It is, therefore, important to ascertain its behavior and clarify the treatment criteria. For quantification of virus transferred to the activated sludge phase, the virus is put in a free state by using an adequate eluate to make measurement possible by means of a plaque forming method. This paper discusses the eluate used in this case and its conditions, and obtains the following conclusions: a basic region including neutral region is more effective than acidic region when beef extract is used as an eluate; among the chaotropic salts used, NaNO3 is the most effective, and has a capability of elution in a wide range regardless of pH; and the optimal eluting condition involves a combination of certain amounts of beef extract and NaNO3 that can block the electrostatic actions and hydrophobic interactions between the activated sludge and the virus. 20 refs., 7 figs., 3 tabs.

    This paper describes technologies and devices suitable for disposing of sewage and waste water produced in a ship. Methods for disposing of sewage in a ship include such physico-chemical disposition methods as disinfection and sterilization, and such biological disposition methods as activated sludge sewage disposition and catalytic oxidation (biological membrane treatment). Sewage treatment devices include a storage tank type sewage treatment device often used in inner sea liners such as ferry boats, and a biological treatment device (aeration device) used as a mainstream in merchant ships, large passenger liners, and governmental ships. With the storage tank type sewage treatment device, sewage is stored in a storage tank provisionally while a ship is cruising in a discharge prohibited sea area, and discharged in a sea area allowing the discharge or when the ship enters a port. The method is simple, but limited in storage volume. An activated sludge sewage treatment device consists of a tank divided into an aeration chamber, a sedimentation chamber and a disinfection chamber, an air compressor, a chlorine dissolving apparatus, and a screen. Sewage is digested and decomposed by activated sludge, and the top clear water is disinfected by chlorine, and then discharged. 1 tab.

    Elevation of a transmission line steel tower is performed by an operator`s own force upon fixing a safety device to prevent a fall on a safety wire (SW) previously installed on a specified tower leg. It is a considerable burden for the operator to move the tower having a height of 80 to 100 m up and down several times a day. In order to reduce the fatigue, a portable, small and light-weight steel tower elevation aiding device was developed. The existing SW is used to fix the device, requiring no additional facility to be fixed on the tower. Safety assurance depends on the safety device on the SW as currently used. The device has pulling force of 50 kgf (the device operates in a range of 4 to 50 kgf to assure workability in elevation and stopping), and elevation speed of 15 to 20 m/minute (equivalent to the present work. The braking force can be adjusted in three steps at descent according to the ability of the operator). An Ni-hydrogen battery is used, capable of two returns on a tower per charge. Considering the device to be transported in mountainous area, the shape is such that a single unit can be put into a backpack. The device can also be used in general construction sites. (NEDO)

    Discussions were given on a method to estimate resistance constituents in wave resistance made in an air chamber of an air cushion vehicle (ACV). An orthogonal coordinate system is considered, which uses the center of a hull as the zero point and is made dimensionless by using cushion length. Flow around the ACV is supposed as an ideal flow, whereas speed potential is defined in the flow field. Then, a linear free surface condition is hypothesized on water surface Z = 0. Number and density of waves were used to introduce a condition to be satisfied by the speed potential. A numerical calculation method arranged a blow-out panel on the water surface, and used a panel shift type Rankine source method which satisfies the free surface condition at Z = 0. Cushion pressure distribution becomes a step-like discontinuous function, and mathematical infinity is generated in the differentiation values. Under an assumption that the pressure rises per one panel where pressure jump is present, the distribution was approximated by providing one panel with inclination of the finite quantity therein. Estimation on wave height distribution in the cushion chamber showed a tendency of qualitatively agreeing with the experimental result, but the wave heights shown in the experiment had the average level decreased as it goes toward the rear of the hull. 5 refs., 5 figs.

    This paper describes estimation of performance of a high-speed boat by using the Rankine source method. An orthogonal coordinate system is considered, which uses the center of a hull as the zero point, and is made dimensionless by using the hull length. The catamaran boat or the single hull boat being the subject of the discussion is supposed to have a transom stern, and to be sailing at a constant speed in the -X direction. A governing equation and a border condition were formulated using disturbance speed potential and X-direction speed differentiation. An inverse specular image was employed as a specular image system upon considering attitude change in the high-speed boat. As to the division of hull surface, the portions protruded above the static water surface were cut off from among the panel data of boat CAD. Considering a high speed condition in which the water surface is completely separated at the transom section, the water level at the transom section was supposed to be at the same height as at the rear end of the hull. Blow-out intensity at the water surface was derived in such a way that a CAD panel of the rear end of the hull is searched and wave height agrees with the height of the transom in the Z direction. A resistance curve may be obtained easily by using a personal computer. 4 refs., 8 figs.

    This paper describes VPP (Voluntary Protection Programs) and current administrative strategies of US Department of Labor, OSHA (Occupational Safety and Health Administration). Although VPP is conducted by the Federal Government or the state governments with original VPP, it is properly a voluntary program in which entrepreneurs independently participate. OSHA inspects the content and execution condition of every program based on a VPP standard, and after certifying a business establishment satisfying the standard as excellent one, OSHA excludes it from inspection objects for a certain period. After such a period, reinspection and renewal are repeated. This system is derived from that a voluntary program proposed by constructor of Calif. in 1978 was markedly effective to protect workers from damages. Safety and health problem includes various keywords such as internationalization, new technology, risk assessment, process control, self responsibility, information opening, and diverse policies. Although uniform regal safety and health measures are important, promotion and establishment of activities by workers and entrepreneurs themselves in a field are also important. 8 refs., 2 figs.

    A report was made on the measurement of data and the results of the analysis at 14 sites of photovoltaic power generation facilities operated under system interconnection by Tokyo Electric Power Company. This type of system is provided in 40 sites as of the end of fiscal 1995, generating 479kw. The items measured were the generated electric energy at all 14 sites, and the quantity of solar radiation, outside air temperature, panel temperature, etc., at limited sites; and the capacity of each equipment, azimuth and inclination of the panel were also recorded simultaneously. Hourly values were used for the analysis. Five minute values were utilized, however, in the examination of the cause of lowered output and in the situation recognition of the influence of the shade or the change of weather. The utilization factor of the facilities was in the average 10.8% in fiscal 1994 and 10.7% in fiscal 1995. The factor decreased slightly unless the panel azimuth faced due south. The utilization factor at the panel inclination of 35 degrees and 45 degrees showed both 10.4% through the year making no difference. The system seemed to show no overwhelming possibilities in coping with electric power demand. The reason was that deviation existed for 2 hours or so in the peak and that reliability was low as basic power facilities. However, it was determined that the system be continuously examined in future. 9 figs., 1 tab.

    During a single-cell disassembly test of molten carbonate fuel cells having been operated for 90 hours to 5500 hours, correlativity was discovered between decrease in the retained amount of electrolyte due to decrease in pore capacity of electrodes and electrolyte plates and the electrolyte loss. The electrolyte loss amount cannot be explained with the conventional mechanisms, thereby a new model was proposed. The cathode has shown very little change in the capacity change in pores with diameters smaller than 2 {mu}m per unit area. The anode has remained almost constant after 1000 hours, but the electrolyte plates have shown remarkable decrease. Therefore, it is possible to estimate that the electrolyte plates should have been the major cause for the electrolyte loss. The result of measuring the electrolyte loss amount agreed well with that estimated using pore capacity curves. This fact suggests that the electrolyte loss can be explained by a new mechanism that hypothesizes the existence of a largest size of retaining pores that can support carbonates and defines that the electrolyte loss is generated from decrease in the pore capacity. 7 refs., 8 figs., 1 tab.

    Discussions were given on a method to suppress coherent noise in data derived from a non-uniform vibration transmitting-receiving point layout in three-dimensional seismic exploration. The discussions attempted suppression of coherent noise by utilizing a prediction filter for the frequency-space zone. The prediction filter for the frequency-space zone is a filter which handles coherent waveforms found in the record as a signal, and attenuates random noise. Methods to remove coherent noise may include paralleling of signals, making the tracing order random, use of an FX prediction filter, restoration of the tracing order, and restoration of the signal positions. As a result of the discussion using a simple model, it was made clear that coherent noise distributed spatially can be suppressed and signals can be extracted by applying the frequency-space zone filter. In addition, the signals extracted by this operation were found to maintain well the original waveforms. 7 refs., 9 figs.

    In FY 1996, aeromagnetic and radiometric survey was performed in the whole area of Hokusatsu district using a helicopter fixed with a stinger mount system with high density 200 m line spacing at low altitude of 80 m, which was the first in Japan. Based on the existing geological maps, Landsat TM data and radiometric data, lithologies and geological structures were extracted in response to individual magnetic characteristics in the whole magnetic map. Obtained geological characteristics are as follows. Straight magnetic anomalies suggested volcanic lava flows. Isolated ring-shaped magnetic anomalies suggested intrusive rocks. Ring-shaped weak magnetic anomalies suggested the centers of volcanoes. Wide range intense magnetic anomalies were caused by deep intrusive rocks. Wide range weak magnetic anomalies were caused by dissipation of magnetite due to hydrothermal alteration. Faults and fracture zones were recognized as linear configurations of magnetic anomaly and divided magnetic anomalies. Based on these results, local geological structures, hydrothermal alterations, and mineralization of known ore deposits were interpreted. 6 refs., 5 figs.

    In this study, the possibility to apply the Distinct Element Method (DEM) to human evacuation behavior during a disaster was investigated, evacuation from rooms to outside though a passage or steps and a jam were examined as a basic consideration. The main results were obtained as follows: according to an analysis of evacuation behavior when elements of DEM were substituted for individual humans, the trace of individual people and force acting there to and the trace of the whole group so every time can be understood, analysis can also be conducted from local to macro. In the DEM analysis, a mutual distance between people and characteristics of behavior can be expressed well by introducing an imaginary bane into the elements. Evacuation time due to change of space shape can be compared and time series change of force acting on individual people can be understood according to the investigation on evacuation time difference due to shape change at the exit and entrance and the jam caused by the arch effect happened when the crowed flow appeared at the exit and entrance. 16 refs., 21 figs., 4 tabs.

    Anfo (Ammonium Nitrate and Fuel Oil)is an explosive consisting of prill ammonium nitrate and light oil that immediately spread across the world upon its debut in the U.S. around 1956, but the details of its birth, for example the name of its inventor, are not known. Granular ammonium nitrate is in production, with its porosity enhanced to elevate oil absorption efficiency to the level for the nitrate to be proper as the material for the anfo by adjusting the water content at approximately 4% in the ammonium nitrate mother liquid before corning. Efforts are being exerted by manufacturers to improve the drying process to remove excess water efficiently from granular ammonium nitrate. In Japan, industrial production of prill ammonium nitrate for the anfo began in 1964. Since then, the problem of anfo sensitivity to detonation has been solved by adjusting the oil absorption rate of prill ammonium nitrate to be in the range of 10-12%, and the problem of ammonium nitrate solidification has been solved by the development of a solidification preventing technology that utilizes solidification preventing agents based on organic surface active agents (while inorganic anti-bonding agents are in popular use in the U.S. and Europe)

    The numerical analysis program based on the difference method for dynamics of sea water with sea-surface displacement, flow rate, salt content and temperature as the parameters is modified to more accurately assess the effects of a huge marine structure on surrounding environment by adding the effects of insolation and boundary conditions of the sea-covering effects of the floating structure. The numerical simulation was done for summer and winter seasons, not in a sea area but using a rectangular bay with the floating structure at the center. A new flow evolves around the floating structure, due to the sea-covering effect. The flow patterns in summer and winter are clearly different, due to difference in insolation. The predicted flow is also sensitive whether stratification is considered or not, by which is meant that it is important what stratification effect is taken into account. Daily insolation changes are accompanied by vertical distribution of water temperature and its temporal change. These effects are also observed under the floating structure which shields insolation. 10 refs., 17 figs., 4 tabs.

    We have applied a fuel behavior model to a fuel injection system which we call SOFIS (Sophisticated and Optimized Fuel Injection System) so that we get air/fuel ratio control accuracy and good driveability. However the fuel behavior under starting conditions is still not clear. To meet low emission rules and to get better driveability under starting conditions, better air/fuel ratio control is necessary. Now we have understood the ignition timing, injection timing, and injection pulse width required in such conditions. In former days, we analyzed the state of the air/fuel mixture under cold conditions and made a new fuel behavior model which considered fuel loss such as hydrocarbons and dissolution into oil and so on. Al this time, we have applied this idea to starting. We confirm this new model offers improved air/fuel ratio control. 6 refs., 9 figs., 3 tabs.

    This paper describes a study of annoyance to road traffic noise in laboratories. To measure the annoyance to road traffic noise, subjective evaluation test was carried out using 48 road traffic noise recorded at various points in the city. Among the frequency spectra of these noise, the differences on the SPL of high frequency component were significant. As a result, we found that: (1) annoyance was different while A-weighted SPLs were the same, (2) fluctuation strength had the highest correlation with annoyance, (3) besides A-weighted SPL, roughness and sharpness contributed to annoyance -simultaneously, (4) contribution of high frequency noise was significant to annoyance. 2 refs., 11 figs., 1 tab.

    Study was made on improvement of the strength of silica aerogel as transparent insulating material. Silica aerogel is a low-density porous material with high heat insulation and transparency. To develop a insulating material with high transparency, monolithic silica aerogel was studied. For direct use of it for windows, its strength improvement was attempted. The aerogel was prepared by supercritical drying (alcohol or CO2) of silica wet gel obtained by hydrolysis and condensation of silicon alkoxide solution. To prepare the aerogel bonded on plate glass for strength improvement, the aerogel was bonded to alkoxide by exposing active silanol radical through F-etching of plate glass surface. However, to obtain the practical large-area bonded aerogel, shrinkage control of the aerogel in supercritical drying was necessary. Addition of Laponite into a silica network for strength improvement by polymer increased the bending strength by 50%. Although some reduction of its transparency was observed because of clouding, its heat insulation was stable. Further strength improvement is necessary for its practical use. 5 figs., 1 tab.

    In direct hoisting work in suspension bridge construction, since a cable crane directly hoists a bridge beam block put on a barge on the sea, precise fixed position holding function is required for a barge. The control system was then designed on the basis of an ILQ control theory, and the effect of change in time constant as design parameter on fixed position holding performance was studied. In addition, the critical disturbance for fixed position holding control was studied through numerical simulation under various disturbance conditions using the above designed control system. As a result, in the design of control systems on the basis of an ILQ control theory, the precise control system could be designed by diminishing, in particular, the time constant for state variable around a z axis among time constants according to the extent of disturbance. The control performance was largely affected by response delay period from sensing of disturbance to beginning of control. 3 refs., 7 figs., 2 tabs.

    The pulse-height distribution of a cushion room of air cushion vehicle (ACV) has been tried to be approached by means of the panel shift type Rankine source method. When using this method, it was not required to introduce the pressure distribution model simulating the fall-off effect for the step-formed cushion pressure distribution. The wave form and wave making resistance could be estimated precisely by assigning the pressure gradient to one longitudinal direction panel in the calculation. The waveform shape within the cushion room could be calculated rather precisely by comparing with the analytic solution. This calculation method did have an ability providing the pulse-height information in the cushion room of ACV for seal design and configuration of ships. The analytic solution using for the comparison was sufficient for determining the pulse-height in the high speed region. However, it was hard to respond to non-linear problems or optional shape problems. It was pointed out to be further improved. 5 refs., 8 figs.

    Among the numerical calculation methods for steady-state wave-making problems, the panel shift Rankine source (PSRS) method has the advantages of rather precise determination of wave pattern of practical ship types, and short calculation period. The wave pattern around the hull was calculated by means of the PSRS method. The waveform analysis was carried out for the wave, to obtain an amplitude function of the original ship type. Based on the amplitude function, a ship type improvement method aiming at the optimization of ship type was provided using a conditional calculus of variation. A Series 60 (Cb=0.6) ship type was selected for the ship type improvement, to apply this technique. It was suggested that optimum design can be made for reducing the wave making resistance by means of this method. For the improvement of Series 60 ship type using this method, a great degree of reduction in the wave making resistance was recognized from the results of numerical waveform analysis. It was suggested that the ship type improvement aiming at the reduction of wave-making resistance can be made in shorter period and by smaller labor compared with the method using a waveform analysis of cistern tests. 5 refs., 9 figs.

    It was intended to confirm, based on various problems surrounding oil flow-out accidents, that oil fences whose use is first considered when an oil flow-out accident occurs cause oil leakage due to oil pass-through phenomenon as the largest defect in performance of oil fences. Therefore, oil fence performance was analyzed by using a simulation. Furthermore, several types of diffusion prevention and avoidance measures, and combinations thereof were evaluated by using multi-criteria analysis. It was also elucidated how recognitions on the importance of methods to prevent oil pollution differ depending on standpoints. Difference in oil flow-out prevention performance of oil fences due to variation in tidal currents was made clear by combining a diffusion simulation using the finite element method with the prevention performance of oil fences relative to the tidal currents. In areas with no good hydrographic conditions where pollution spreads rapidly, it is necessary to suppress oil diffusion by extending oil fences double or triple, and using gelling agents. 4 refs., 8 figs.

    In order to increase a fluid dynamic understanding of the flow field around the measuring part as for the leveling of free surface of the circulated flow tank for measurement, the velocity and free surface profile at the measuring part have been calculated by applying the numerical fluid dynamics. The results were compared with actual phenomena. For the average velocity at the measuring part, inclining angle of surpressing plate, and quantity of water in the tank, the flow field simulation by the numerical fluid dynamics has provided a qualitative agreement with actual phenomena. Especially, it was clarified from the viewpoint of numerical fluid dynamics that the fine adjustment of the inclining angle of surpressing plate and quantity of water in the tank greatly affect the creation of horizontal free surface at the measuring part. Furthermore, effects of the length of measuring part and the ceiling tilt angle of pipe conduit in the downstream of measuring part, which were hard to be analyzed experimentally from the viewpoint of facility and cost, were investigated. Consequently, it was clarified that there are critical length of the measuring part and optimum ceiling tilt angle in the leveling of horizontal free surface. Thus, an instruction for designing was obtained. The present flow field simulation was useful for the fluid dynamic understanding of the flow field at the measuring part, as for the leveling of horizontal free surface. 1 ref., 8 figs.

    This metal melting system is a process to efficiently melt and regenerate scraps of aluminum, copper and iron by utilizing high-temperature energy obtained from pulverized coal-oxygen combustion. The process is intended to utilize coal in place of petroleum for reduced fuel cost. Joint studies have been carried out as a subsidy operation of the Agency of Natural Resources and Energy with a schedule of six years starting fiscal 1992. Development tests are being performed using a 5-ton/ch pilot plant facility since fiscal 1995 after having gone through experiments using a 1-ton/ch bench scale furnace. This paper reports the results obtained to date. Using the pilot plant facility, fiscal 1995 has achieved the initial target values, such as thermal efficiency of 55% or higher, and yield of 96% or higher for non-ferrous metals and 94% or higher for iron. The melting behavior in the furnace has improved the thermal efficiency as a whole by retaining the conditions in the preheating step for an extended period of time. The thermal efficiency has been improved better than with the bench furnace as a result of upscaling effect. 9 figs., 3 tabs.

    This paper reports an outline of investigation results of earthquake damage estimation carried out in Akita Prefecture. The basic policy for this investigation consists of the following: (1) an indication on existence of a blank area in the Akita off-coast earthquake shall be viewed so importantly that a fault model is set to estimate damages; (2) because most of the earthquakes in history of Akita Prefecture are inland earthquakes with magnitude of about M=7, four earthquakes in the past shall be adopted as the set model; and (3) the central Sea of Japan earthquake in 1983 was an earthquake occurred in the Sea of Japan side and caused a great deal of damages to Akita Prefecture, and its epicenter model and damages were investigated in detail, hence these data shall be utilized in verifying the procedure and method for estimating damages studied in the present investigation. This paper reports finally estimated human damages. With an assumed earthquake as strong as the Tencho earthquake in the year of 830, more than 1000 deaths will occur in the city of Akita; with an earthquake in the scale of the Noshiro earthquake in 1694, more than 50 deaths will be counted in the city of Noshiro; one as strong as the Rikuu earthquake in 1896 will cause about 300 deaths in the cities of Yokote and Omagari, respectively; one with the scale of the 1914 Goushu earthquake will result in about 300 people to be killed in the city of Omagari and about 200 people in the city of Yuzawa; and an earthquake estimated to occur in the blank area off the Akita coast will force 33% of the residents of the Kisakata town to be evacuated from their homes. 1 fig.

    The paper described JCOAL`s project on the exchange of technical coal engineers of China. In the project on sending of engineers to China in the first term, coal mine engineers of Japan (Taiheiyo Coal Mine, Kushiro Works, Training Center) were sent to the Daitun coal-thermal power plant, Peixuan city, Jiangsu province, in September, 1997 to introduce the production control technology in Japan. They contributed to the heightening of productivity in coal mines in China. Eighteen Chinese participated in the training. Mechanization has been comparatively well in progress, and it was 83% in coal mining and 91% in drilling. The kind of coal is mostly a raw material coal. The stuff members are 30,000, and expert engineers are 4,200. The plant has an output of 130,000 kWh, owns its railroad, is run on the general multiple management, and is largely developing. The project on sending of engineers to China in the last term was carried out in February 1998 for tracing/confirming how the results of the training conducted in September are made the most of and if or not there is something bad and for obtaining the detailed data. A certain degree of promotion and effects were able to be confirmed. A project on training of the head, sub-head, etc. who were invited to Japan to lean production/management control was also carried out in November and December 1997. 1 tab.

    A radiation thermometer was applied to the measurement and analysis of radiation temperature of the material surface. In this paper, the characteristics of the radiation temperature and the radiosity coefficient of gray body materials are investigatied. An infrared radiometer was used, which detects radiation energy in the region between 8 and 13{mu}m of wavelength. This infared radiometer has a Hg-Cd-Te photon radiation sensor. The variation of emissivity was measured for the four kinds of non-metalic materials, i.e., graphite, carbon fiber composite, Si-SiC ceramic, and black paint spread on an aluminum plate. As a result, the relationship between material temperature and radiation energy was made clear. Furthermore, the space-dependent variation of the radiation temperature and the radiosity coefficient was derived from the two-dimensional CRT image of the infrared radiometer. Consequently, the emmisivity variation gave a maximum for the carbon fiber composite surface rich in irregularity, and decreased in the order of graphite, Si-SiC, and black paint. 7 refs., 15 figs.

    Phosphonic acid-based inhibitors that are poured into cooling water for copper-tube circulation systems for open heat-accumulators were studied on their influence on pitting corrosion of copper. Amino trimethylene phosphonic acid (ATMP) dissolved into distilled water to 50 ppm was used for the immersion corrosion test. The corrosion-proof effect of additives such as ZnSO4, benzotriazole (BTA) was tested too. 0.5 mm thick phosphate-treated copper plates with a hole of 5 mm in diameter were used as test specimens. Pitting corrosion on the copper plate occurred when ATMP, BTA and ZnSO4 coexisted. It was proved that SO4 [sup 2-] is essential since Na2SO4 in stead of ZnSO4 induced also corrosion. The pitting took place when 0.6 ppm or more of SO4 [sup 2-] was present in a BTA-added ATMP solution. It was observed that the pitting is prone to occur with increase of SO4 [sup 2-] and the number of pitting increases. The following relationship is established when pitting corrosion occurs; E[sub b] [le] E[sub corr], where the former is a potential value at which current density shows a steep increase and the latter is an average value of spontaneous electrode potential showing a plateau. 8 refs., 11 figs., 1 tab.

    Since ocean waves encountered by ocean vessels or offshore structures in actual sea areas present extremely irregular variations, a stochastic method is necessary to estimate their statistical properties. This paper first shows a calculation method for probability density function for water level variation which strictly incorporates a secondary non-linear effect containing directional dispersibility by modeling ocean waves as short-crested irregular waves. Then, the paper specifically elucidates effects of the directional dispersibility of ocean waves on statistical amount of amplitudes by deriving the statistical amount of the amplitudes based on the probability density function of the water level variation and by using a numerical simulation. The paper finally takes up data of waves in stormy sea observed in an experiment in an actual sea area, compares the result with that of theoretical calculations, and evaluates reasonability of this method. With this estimation method, individual secondary components or components of difference and sum may be subjected to influence of the directional dispersibility, but they do not differ much from the case of long-crested irregular waves on the whole. 21 refs., 11 figs., 2 tabs.

    A trash removal system working by current energy has been developed for agricultural waterway. It consists of a wheel, shaft, screen and conveyor to exhaust collected trash. Current energy is converted by the wheel into rotational power, which drives the screen lake and conveyor. It is installed in an agricultural water way, 1.2m wide, 1/5000 in gradient and 1m/s in flow speed. Observed in the field test were service conditions of the system and torque limiter, water level at each portion, wheel speed, and types and quantity of trash collected. It is found to be serviceable at a low cost. The troubles, such as noise and bent lake occurring when the chain is out of place, have been solved. The test also has clarified types of trash discarded in the waterway. 3 refs., 11 figs.

    Described in this paper is a technique of solar radiation spectroradiometry in which high-resolution wavelength computation adds to a multi-filter method. The solar spectrum upon entering the atmosphere is scattered and absorbed by parameter-constituting elements such as gas, aerosol, cloud particles, etc., and its spectral contour is complicatedly deformed relative to wavelength. Taking advantage of the fact that the scattering and absorbing characteristics of some of the elements are constant relative to wavelength, a simple equation was constructed to enable high-resolution spectrum measurement wavelength-wise, and this compensates for the limit in measurable wavelength that the conventional multi-filter method suffers from. The new method discussed here is not so expensive as the grating method thanks to the employment of filters, is capable of determining spectral radiation quantities with a precision of {plus_minus}5%, and is reduced in terms of the capacity of memory for data storage. The new method enables data collection under various atmospheric conditions that the four seasons present, which the difficult-to-apply and expensive spectroradiometer fails. It is expected that this method will find its use in collecting basic data for the designing of photovoltaic power generation systems, in the study of photochemical reaction in agriculture, and in collecting basic data for daylight lighting. 1 ref., 6 figs., 2 tabs.

    Performance of a solar heating system with a hydrothermal source heat pump was evaluated and compared with that of a direct solar heating system. The sun-dependency rates ({Sigma}D and {Sigma}H)of the direct system and heat pump (HP)-provided system were expressed as a function of the rate ({alpha}) of the auxiliary heat against the collected heat and as a function of the performance coefficient and {alpha}, respectively. When the sun-dependency rates are compared, it is found that the HP-provided system is the more advantageous when {Sigma}H/{Sigma}D>1. The relationship between the {alpha}`s of the two systems was clarified and computation was performed to compare the sun-dependency rates on condition that the two are equal in the heat collecting area. Although the sun-dependence rate cannot be elevated to 100% in the HP-provided system, it achieves a sun-dependency rate higher than that of the direct system even when the heat collecting area is small. In cases where the building is economically limited, for instance, with respect to the area for solar collector installation, it is advantageous to employ the HP-provided system. 5 figs., 1 tab.

    Although Japan`s shipbuilding industry has been maintaining a seat for the first place in the world over 30 years or more in a contract award quantity for the new shipbuilding work, Korea got ahead of Japan and has come to be a top at the first time in 1993. Even though the various factors could be thought, it has become a turning point to be reconsidered how Japan`s shipbuilding industry should be from now on for the naval architects and persons concerned in Japan. While Japan`s production of the maritime industrial products has been in general showing the recovering tendency by a demand restoration of the large scale vessels and so forth since 1987 afterward, on the other hand, affected by an influence of the recession of the world economic activities, the total production amount in 1993 has turned to a little bit decrease and its amount was 831.8 billion yen (a ratio to the previous year: 96.4%). Though a business environment surrounding the maritime industry, in order to successively continue the work shop site inside this country as an important industry through this industry from now on, it is thought that a restoration of the price competition should be made an effort on one hand by a standardization of the maritime equipments and tools making an exclusion of the wastefulness as an object, and a strengthening of the international competitiveness at the non-price aspects such as a functionality of the products, a reliability and so forth is indispensable on the other hand. 6 figs., 3 tabs.

    A proposal is made on a method to analyze a slope disaster in detail from a viewpoint of ''where the disaster occurred'' (to analyze in a line pattern the apertures of a collapse and main scarps in a land slide). Methodological emphasis was placed on superimposing aerial photograph images taken before and after a disaster over imaged information on factors based on land conditions including topographical characteristics. Applicability of this method was discussed using a landslide location in Niigata Prefecture as an example. This paper describes the result of tb discussion by the following items: Imaging the aerial photographs and correcting their geometrical distortion; extracting items of line-pattern information from the aerial photographs and classifying the land coverage; and analyzing factors of causing the landslide using an image superimposing process. The papers also mentioned a view that this method may be applied effectively on disasters occurring on ground surface. 11 refs., 8 figs., 2 tabs.

    It is well known that the landslides in Tertiary systems abundantly found in Niigata Prefecture, etc., frequently occur especially in the snow melting season or the heavy rain season. For studying the occurrence of such landslides, exploration of the actual condition of groundwater and evaluation of the strength of earth are very important even when the landslide occurring mechanism can be presumed in a relatively simple way about the soil mechanics. Therefore, great importance is attached to the observation and investigation on the groundwater level and pressure at landslide sites and stability analyses have been actively performed. However, it is considered that several fundamental problems still exist in the method for estimating the groundwater level and pressure in landslide slopes from the observation method and data on groundwater levels and pressure (pore pressure). In this paper, these fundamental problems are examined on the basis of concrete observations made by the writers on landslide slopes at Matunoyamagoe and Higashimusikame landslide sites in Niigata Prefecture for the past several years. 6 ref., 6 figs., 2 tabs.

    This paper reports the design and construction of landslide preventive construction at the site of the Yamasubara hydroelectric power plant (with a maximum output of 40,700 kW) and the result of slope stability verification after completion of the construction. The moderate slope on top of the primary slide has sands presumed to be colluvial deposit distributed with a depth of 10 m or more, where occurrence of a secondary slip was feared as triggered by the primary slide. The power plant protective constructions consisted of concrete walls to protect the entire power plant including buildings, and falling stone protective fences installed around the surge tanks. The temporary measures were so set that groundwater levels are lowered to a level that can assure the slide safety factor of 1.0 or more by means of drain boring using the down-the-hole hammer type. The permanent protective construction used rock anchors that are superior in constructability and economy. The stability of sliding slope faces was verified to confirm effects of the protective constructions. The verification included observations of groundwater level behavior, water well-up from drain holes, and movements in the slopes. The result showed that the protective constructions have give sufficient effects. Continued slope stability control is important. 16 figs., 7 tabs.

    Excitory impulses for motor systems are controlled by the psychophysiological nervous systems in the body either autonomically or voluntarily. Involved in the voluntary control loop are motor cortex, basal gangalia, thalamus, cerebellum, etc. The purpose of this study is to confirm whether it is possible to reduce or emphasize the muscle contraction voluntarily through electromyogram (EMG) feedback training. EMG can indicate the excitory impulses of motor units. In the experiments, electrodes were placed on the skin above muscles. A significant reduction effect was observed for subjects trained in relaxation of the forehead musculature through EMG feedback. Results of the experiments suggested that biofeedback training for relaxation of the forehead tensional muscle might be effective in eliminating muscle contraction, and that feedback training for activation of damaged muscles might be effective in emphasizing muscle contraction. 4 refs., 9 figs.

    Moulds prepared by uniform hardening were stored in normal foundry atmosphere and in the humidity controlled chamber to investigate properties of mould. Then, the relationship between the reaction rate of CO {sub 2} and Na {sub 2} 0 contained in mould binder and mould strength was studied. Followings were found: Turning point between absorption and desorption of mould exsits between 81-83% relative humidity (RH). Under the hith RH of the turning point or more, more the water glass addition, more the absorbed amount. When moulds were stored in the humidity controlled chamber, close relation was found between RH%, desorption or absorption rate and mould strength, that is, higher the desorption rate, higher the strength. Further, the reversible relationship was found between the strength and absorpion or desorption rate. Although any deterioration of strength was not found for moulds stored in the humidity controlled chamber (RH of 44-81%), moulds stored in normal foundry stmosphere lost the strength or deteriorated gradually. 7 refs., 11 figs., 2 tabs.

    This paper describes organic materials for semiconductor. Based on the composition and raw material, typical materials are epoxy resins, curing agents including phenol-novolak resins, fillers including silica and alumina, flame retardants including brominated epoxy resin and antimony oxide, hardening accelerators including amine compounds and phosphorus compounds, coupling agents including silane compounds and titanate compounds, and the others including colorants and mold lubricants. Raw materials are heated and kneaded after mixing, and produced as tablets after cooling and crushing. Recently, the packages have changed from insertion type to surface mounting type for the small thin IC package and for improving the efficiency of soldering during the incorporation of IC package on the print circuit substrate. High temperature of 260degC has been employed from the conventional limit of 100degC. Reduction of water absorption, improvement of adhesion, reduction of thermal expansion coefficient, and reduction of elastic modulus during heating are promoted for avoiding the peeling and cracking due to the sudden evaporation of adsorbed moisture. This paper also describes the organic materials for BGA. 10 figs., 4 tabs.

Consequently, this system was effectively able to use for these measurements and analysis and introduced the correlation between the vehicle movement and the driver`s action. 4 refs., 12 figs., 2 tabs.

    A plurality of parallel cables have been recently employed for long-span cable-stayed bridges. Use of such parallel cables thereupon leads to a special type of wind-induced vibration called wake galloping (simply referred to as WG.) owing to air turbulence caused by upstream cables. This paper attempts to evaluate measures against the WG using a wire connecting method, and identifies the most important influencing factor and the validity of the measures through wind tunnel tests. The following results are hereby clarified. Even if the deformation rigidity of the cables is increased, it is impossible to raise the wind velocity of the WG. The wind velocity of the WG can not be reduced from a wind tunnel wind velocity using non-dimensional wind velocity. The wire connecting method proves to be more effective for reducing the amplitude of the vibration. Provided cables are coupled into a multi-stage using the wire connection method, overall vibration with a greater amplitude can be restricted. To the factor of the restriction additional deformation rigidity of the cables more contributes compared with additional weight of the cables. 9 refs., 13 figs., 2 tabs.

    Demand side management through a pricing mechanism, that is the indirect load control was experimented to analyze the pricing effect. When power consumption in indirect load control groups is compared between peak time band in weekdays in summer and off-the-peak time band, the power is less consumed when price gap is set than in a uniform charge time. When more number of persons is in home in daytime, room cooling is used in daytime including the peak band to adjust the demand. The substitution elasticity in price between demands in the peak time band and the off-the-peak time band is from about 0.06 to 0.07, which cannot be ignored. If the peak price is increased by four times, the demand in the peak band can be reduced by about 0.15 kW (when average power demand per household is assumed 0.75 kW). For room cooling devices, the first device is often installed in a living room and the second and further units in individual rooms such as bed rooms. The more the number of device, the higher the possibility that the use time band is outside the peak time band. This indirect load control experiment is a field test related to the peak-activated pricing for small power users, by which the users` behavior against the pricing effect was identified quantitatively. 5 refs., 1 fig., 8 tabs.

    In the study of seismic wave propagation, a model experimenting technique has been developed using a laser Doppler velocimeter (LDV) as the sensor. This technique, not dependent on conventional piezoelectric devices, only irradiates the specimen with laser to measure the velocity amplitude on the target surface, eliminating the need for close contact between the specimen and sensor. In the experiment, elastic penetration waves with their noise levels approximately 0.05mm/s were observed upon application of vibration of 10{sup 6}-10{sup 5}Hz. The specimen was stainless steel or rock, and waveforms caught by the LDV and piezoelectric device were compared. As the result, it was found that the LDV is a powerful tool for effectively explaining elastic wave propagation in inhomogeneous media. The piezoelectric device fails to reproduce accurately the waves to follow the initial one while the LDV detect the velocity amplitude on the specimen surface in a wide frequency range encouraging the discussion over the quantification of observed waveforms. 10 refs., 7 figs.

    Clearance provided between two flat resin blocks (being stacked) used as a model of a crack in rocks was subjected to an experiment to investigate elastic wave propagation characteristics when the crack is filled with water and when injected with air. This paper reports the result of the experiment. The experiment was carried out on a case where a parallel flat layer of water (with a thickness of 2 mm) was used as a crack and a case where crack faces are contacted (small resin pieces are inserted into the crack). The experiment was conducted by injecting air bubbles (air) into the water saturated crack from its side to gradually expand the air bubble existing region. Seven ceramic piezoelectric elements (one is a vibration source) were arranged on top of a resin block and six elements beneath the block to measure a wave reflected from the crack face and a wave permeated through the crack. It was found that as the air bubble existing region is expanded, the amplitude of the permeated wave decreases remarkably (however, only to a certain level when the crack faces are contacted), and the amplitude of the reflected wave increases. 3 refs., 9 figs.

    The Hanshin/Awaji earthquake disaster caused extensive damage to many bridges of the Hanshin Expressway. N particular, falling-down of superstructures and other destructive damage occurred at Benten Kouku which located in downtown of Kobe. After the earthquake disaster, the continuous 19-span space frame bridge with lead rubber bearings which had approximate 565m bridge length was reconstructed in this region. It is the first trial in Japan to use large lead rubber bearings as an isolator or as a damper at the bottom of the steel pier for the purpose of reduction of seismic force acting on this bridge. As the lead rubber bearings, a spring member was used. In this study, by using jack with a raid releasing mechanism, monotonous loading tests loading statically at the bottom of the pier and rapid releasing tests deloading loads in a moment were carried out. Further, the simulation of the experiment was conducted on the analysis and the analytical model was established in comparison of the experimental data and the analytical data. Using this model, owing to carry out the seismic response analysis, more reliable analytical results were obtained. 22 refs., 24 figs., 3 tabs.

    The combined natural convection and radiation heat transfer characteristics in a vertical porous layer with a hexagonal honeycomb core were investigate experimentally. The temperature distributions on the honeycomb core wall and the combined heat transfer rates through the porous layer were measured. The measurements of the heat transfer were accomplished using the guarded hot plate (GHP) method. The honeycomb core wall was made of paper and large mesh foamed resins were inserted into the honeycomb enclosures. The measurements were performed while varying the radiation parameters between 0.5 to 0.65, varying the temperature ratios between 0.01 to 0.1 and varying the Darcy-Rayleigh numbers between 5 to 80, and for a fixed aspect ratio of H/L=1.

    A heat pump driven by electricity is one of the excellent electricity utilization systems and is promoted to be widely used. An advanced heat pump has been investigated to enlarge its applications in the field of hot water supply for domestic use which will be competitive with city gas and air conditioning in large scale buildings. An experimental unit with two-stage compression system was designed, which has the multi-function of air conditioning and hot water supply, and the trial system was fabricated. In the design, followings were considered; cooperative operations of two compressors by inverter driving, the temperature conditions of both the air for the air conditioning and the heat source, additional setting of the intermediate heat exchanger. The test operation was carried out with checking the start up procedure, the control sequence and so on. The probability of five operation modes: cooling, heating, hot water supply, cooling/hot water supply, and heating/hot water supply, were confirmed. In the mode of heating/hot water supply the hot water temperature was increased to 65/sup 0/C, the excellent performance in hot water supply was demonstrated. (21 figs, 8 tabs, 1 photo, 5 refs)

    A solar chemical heat pump is intended to attempt multi-purposed effective utilization of solar energy by raising low temperature solar heat of about 100 degC to 150 to 200 degC by utilizing chemical reactions. The chemical heat pump under the present study uses a 2-propanol (IPA)/acetone/hydrogen system which can utilize low-temperature solar heat and has large temperature rising degree. It was found from the result of experiments and analyses that IPA dehydrogenation reaction can improve more largely the heat utilization rate in using a falling-liquid film reactor than using a liquid phase suspended system. As an attempt to improve further the heat utilization rate, this paper reports the result of experimental discussions on inclination angles of a reaction vessel and feed liquid flow rate which would affect the fluid condition of the liquid film. As a result of the experiments, the initial deterioration in the catalyst has settled in about 15 hours, and its activity has decreased to about 60% of the initial activity. It was made clear that the influence of the inclination angle of the reaction vessel on the reaction is small. 5 refs., 7 figs.

    The experiment and survey were carried out to verify the effectiveness and limitation of MT method. The previous seismic reflection method is unsuitable for steep terrain and over-folded complicated geological structure. In such difficult areas, application of MT method is increasing as complement or substitution for the reflection method. However, the evaluation of resistivity structure interpretation for every area is slightly difficult because of lack of data, poor quality of data, and no verification data at boreholes. Consequently, the survey was again carried out in well-known Yurihara oil and gas field, Akita prefecture whose geological structure has been surveyed in detail at boreholes, by adding new 32 sites, 22 sites on the south side and 10 sites on the north side of the measuring line extending from east to west. As a result, it was clarified that the lower high-resistivity layer found by MT method is equal to the Nishikurosawa basaltic layer, and basalt extends to the west in the north area. This result can`t be simply compared with the previous geological profile. 8 refs., 8 figs.

    In this experiment, a beam incident from an oblique direction is reflected by a spherical lens toward the direction of incidence. When the surface of a matter is vibrated by elastic waves, the spherical lens comes into a translation motion that accompanies the vibration. It follows accordingly that the vibration on the surface of the matter may be detected by sensing the spherical lens travelling speed. Three components of the vibration may be determined if beams are focused at one spot from three directions. Detection of the S-wave component by LDV (laser Doppler vibrometer) discloses the complicated wave field in a heterogeneous material, and this physical model experiment may be utilized in various fields of study. For instance, information about problems that may surface in the field work may be collected beforehand in a physical model experiment for developing an S-wave-aided probing method. For the study of seismic wave propagation in a complicated three-dimensional ground structure, a numerical model is not enough, and a physical model experiment will be an effective method to fulfill the purpose. In the monitoring of cracks in a rock, again, not only elastic wave velocity but also waveform information collected from a physical model experiment should be fully utilized. 6 refs., 6 figs.

    This is a prompt report. These days the importance of acquiring knowledge about the structure from the lower crust down to the upper mantle is often discussed with reference taken to Hyogo-ken Nanbu Earthquake. The Hidaka collision belt where the lower crust is exposed on the surface is a rare phenomenon in the world and has been the subject of seismic survey. As a part of the survey, experiments are conducted by the use of vibrations produced by Vibroseis and dynamite sources. Every one of the shot records (20-second record) from the two types of vibration sources contains a clear echo in the vicinity of 16 seconds supposedly from a level deeper than 40 kilometers, not to mention reflections from shallow levels. Although some studies have to be conducted before the reflecting geological boundary (possibly the upper mantle) of the echo near the 16-second point can be identified, yet this is probably the reflection from the deepest level ever obtained in the seismic reflection survey conducted in Japan`s land area. It is proved by this experiment that vibration from a vibrator can reach as far as that from explosion if the vibrator specifications are rightly chosen. 4 refs., 3 figs.

    Effect of water injection/draining on elastic waves penetrating through cracks is examined by measuring elastic waves before, during, and after the injection/draining of water into/from cracks in presence in granite. Two blocks of rock, with their crack-containing surfaces in contact with each other, are placed in a vessel, and water injection/draining is done through a hole on a vessel bottom side so that water will penetrate into the cracks. When the blocks are dry, there is almost no contact between the cracks, and so no crack penetrating waves are observed. Crack penetrating waves are produced when water is injected, and the position of the receiver sensing the penetrating waves changes as the water level rises. When the water level is lowered from the high water level, the waveform changes again as the level changes. The change in waveform is not so remarkable, however, as that observed during water injection thanks to the water residual in the cracks. It is now inferred that crack investigation is more effective when it is carried out with water being injected into dry cracks. The difference produced between the dry state and wet state when water is injected into dry cracks is used to detect the presence of cracks in this experiment, and this may be applied also to the investigation of cracks in the shallow part of the ground. 4 refs., 11 figs.

    The storage tank is classified into a mixed type and stratified type. The stratified type is judged to be more advantageous from a viewpoint of the effective energy utilization. An experiment was made using a solar simulator to put the system, consisting of a vacuum double-glass tube collector and temperature selective storage tank, to practical use. The ejection position of the storage tank at the top is superior to that at the bottom, in the 60{degree}C layer of three layers (60, 40, and 20{degree}C). The ejection position hardly varies with the shape (straight or elbow) of an ejection port. When the temperature stratified layer is formed in two layers (40 {times} 2, 20{degree}C) to three layers (60, 40, and 20{degree}C), heat can be stably stored as the flow rate is higher. The stratified storage tank is inferior to the mixed storage tank in heat collection efficiency, but the specific exergy increases. By increasing the number of heat storage layers, the result of this experiment can also be applied to the linear temperature gradient layer obtained in the practical use. As a result of the above experiment, the basic data for an automated system design during practical application was obtained. 3 refs., 15 figs.

    An experiment on heat collection was made in the heat collector of a solar system utilizing outdoor air in cold and warm regions. In this system, outdoor air is heated by the air circulation layer on the roof exposed to solar radiation. The heated air is supplied to the object space for heating and ventilation. In the experiment in a cold region, the heat collection characteristics can be adjusted by putting a baffle plate in the air duct according to the experiment of a glass heat collector. The heat collecting air layer on only the iron roof may leak or freeze in the region subject to coldness or heavy snowfall. Therefore, preheat forms the space of a garret, and the preheat temperature comparatively becomes low. The data in which the heat collection characteristics can be adjusted using only a glass heat collector is required corresponding to the regional situation. In the experiment in a warm region, an experiment was made inclusive of the preheat for which outdoor air is absorbed at the eaves. As a result, the heat collection characteristics of preheat were improved. Moreover, a heat collection temperature of about 60{degree}C was obtained on the heat collection surface including the preheat. 1 ref., 12 figs., 3 tabs.

    An experiment and the examination were carried out in order to elucidate the optimum conditions in the falling liquid film reaction method, in the conversion of solar energy using the decomposition reaction of 2-propanol. The device for the experiment was constituted of a reaction container, tubular pump, cooling pipe, sampling container for effluent from the upper and lower part of the reaction container, and gas burette. Examined in the experiment were various factors such as a fibrous activated carbon (catalyst support), ratio for carrying catalyst, catalytic composition and heating temperature. In the experiment, with the temperature inside the reaction container fully stabilized under prescribed conditions, measurement was done for the hydrogen generation by the gas burette for 10 minutes as well as for the sampling of effluent. The experiment revealed that the heat utilization ratio reached the maximum of about 27% when the heating temperature was 90{degree}C using a catalyst with the ratio of RU and Pt 1 to 1 and the ratio for carrying catalyst 10wt%, so that a great improvement was obtained in the heat utilization ratio at a low temperature. Also obtained was a large inversion ratio of about 15%. 4 refs., 6 figs., 5 tabs.

    This paper examines the dynamic characteristics on the model of the beam supported by one cable, the most simple type of cable-stayed bridge, with fundamental and important linear and nonlinear internal resonances from the experimental and analytical aspects. Vertical oscillation of the beam is able to cause parametric oscillation of the cable, so that dynamic phenomena which derive from internal resonance such as saturation of amplitude of vertical oscilation of the beam are observed experimentally. Based on the concept of local and global oscillation modes, a 3-DOF(degree of freedom) model is formulated considering the geometric nonlinearity of the cable. Then, a test of a small model, taking notice of linear compound of the cable and the beam as well as autoparametric compound by quadratic nonlinear terms, is conducted under vertical and horizontal harmonic excitations. After identifying the parameter of the model, the experimental value is compared with the analytical value. As a result, it is shown that both of them are highly consistent with each other. 16 refs., 9 figs., 2 tabs.

    The peak period of the horizontal/vertical spectral ratio of microtremors was referred to the underground structure for the purpose of finding out if it was possible to estimate the ground structure by use of the peak period of the spectral ratio. The observation was carried in the areas of Morioka City and Hachinohe City using seismographs for measuring east-west, north-south, and up-down motions. As for the relationship between the peak period of the spectral ratio distribution involving 490 observation sites and the known gravity anomalies in the Morioka City area, it was found that the peak period of the spectral ratio tended to be shorter from west toward east while the gravity anomalies were greater from west toward east. Again, as for the relations with the underground geology, the period was longer when the distance to the granite basement was greater, and shorter when smaller. In the Hachinohe City area, relations not only of the first period peak but also of the second period peak to the basement were disclosed, which indicates the possibility that the peak period of the spectral ratio will be used as a means for estimating the basement structure. 2 refs., 8 figs.

    The paper studied output characteristics of photovoltaic modules different in installation conditions on the basis of the energy balance state. In the study, an energy balance equation was constructed for insolation intensity, heat losses from PV surface/back, and output, in order to calculate cell temperatures in each installation condition. A comparative study was made between calculated results and measured data obtained on the top of the school building. The results indicated the following: The thickness of thermal boundary layer became approximately 27mm at insolation intensity of 800 W/m{sup 2}, ambient air temperature of 25degC, and wind velocity of 0.5m/s. When widening air gap from 20mm to 40mm, the cell temperature decreased 4degC, and the output increased 1.6%. In the case of installing photovoltaic modules on the roof considering the relation between the air gap in the heat balance state and the thickness of thermal boundary layer, heat from PV back was released outside the air gap if widening the air gap to more than 30-40mm. The type with a heat insulating material on the panel back decreased in output from other types. 5 refs., 7 figs., 4 tabs.

    This is a detailed report on a 2-week tour made in May, 1997, as part of the `9th regular interchange with energy-related organizations in Europe,` during which tour visits were paid to energy agencies and institutes of Germany, the Netherlands, Sweden, Denmark, and France, and on-site investigations were conducted. The text describes, taking reference to a rich stock of data it carries, the nature, politics and economy, demand for energy, policy toward new energy, for each of the host countries. In the European countries, with the exception of France, efforts are being exerted to introduce new energy and to enhance its application, renewable energy in particular, in place of atomic power. The expectation they entertain toward new energy is far extensive than that of Japan which retains atomic power generation. Although wind power generation enjoys the overwhelming popularity over others, yet, in Germany and Sweden, it will be difficult for this technology to take the place of atomic power generation completely. As for photovoltaic power generation, not so much is expected from this technology as in Japan because of their climate and weather. 67 figs., 10 tabs.

    Relation between fracture toughness and pressure condition in autoclave molding of GF composite laminates is investigated. Glass/epoxy prepregs are molded under different curing pressures, and UD laminates of [O{sub 8}]T and [O{sub 16}]T are fabricated. The results of the double cantilever beam (DCB) test show that the curing pressure has certain influences on the interlaminar fracture toughness via the change in morphology of matrix resin and fibers between laminae, and via the change in interfacial strength of fiber and matrix. It is also found that the fiber/matrix interfacial strength increases as the curing pressure increases by SEM photographs of the fracture surface in GF UD laminates. 13 refs., 12 figs.

    This paper describes the distribution of Curie point depth and its characteristics determined from the spectral analysis of magnetic anomaly data in East and Southeast Asia. It also describes relationships between the Curie point depth and the other geophysical information such as topography, heat flow data and tectonics. The Curie point depths are shallower than about 10 km at volcanic and geothermal areas, between 15 and 25 km at island arcs and back arc rifts, deeper than 20 km at continents, and deeper than 30 km at trenches. The Curie point depth (Dc) estimated from the heat flow data can be expressed by Dc=k{theta}c/q where k is thermal conductivity, q is heat flow, and {theta}c is Curie point. Based on the Curie point depths obtained from Curie point depth analysis in the cross section of northeast Japan and the averaged values of heat flow at individual points, they are distributed along a line of k{theta}c=1500[Wm{sup -1}]. Values of k{theta}c are small near the axis of Japan trench and large in the northeast Japan. It is considered that local anomalies can not be grasped from the spectral analysis. 21 refs., 3 figs.

    It was intended to elucidate characteristics of distribution of damages caused by an earthquake which occurs directly below an urban area. Therefore, numerical simulation using the pseudo-spectral method was performed on characteristics of seismic wave propagation in non-homogenous media composed of rock beds and sediment beds, and of seismic wave amplitudes on ground surface. The simulation has utilized information on underground structures disclosed by using the latest physical exploration method. The underground structure model assumed a two-dimensional model hypothesizing presence of upper, middle and lower beds in the Osaka bed group on granite, using as reference the information on S-wave velocity underground structure revealed by the microtremor exploration method. With an objective to elucidate characteristics of distribution of collapse ratio in the area from 8-chome, Okamoto, Higashinada Ward, Kobe City to 2-chome of Sakanasaki Minamicho, as damages suffered from the Hyogo-ken Nanbu Earthquake, a simulation has been performed varying the structure model based on the results derived by the microtremor exploration method and the reflection method. As a result, it was shown that the characteristics of the maximum amplitude distribution of displacement of ground surface, velocity and acceleration agree well with those of the collapse ratio distribution, and that the simulation using the pseudo-spectral method is an effective means to analyze the ground surface collapse ratio distribution. 5 refs., 3 figs.

    By recent developments of exclusive rotor blade, the efficiency of wind turbine is improved substantially. By measuring pressure on rotor blades of horizontal axis wind turbines rotating in wind tunnels, this report clarified relation between improvement of pressure distribution on main rotor blades by Mie vane and upgrade of wind turbine performance. The results under mentioned have been got by measuring pressure distribution on rotor blades, visualization by tuft, and measuring resistance of Mie vane. (1) The difference of pressure between suction surface and pressure surface on the end of rotor blade increase, and output power of wind turbine improves. (2) Vortex of blade end is inhibited by Mie vane. (3) The reason of reduction on wind turbine performance with Mie vane in aria of high rotating speed ratio is the increase of Mie vane flow resistance.(NEDO)

    When a general view is taken of coal chains that connect overseas coal suppliers to Japan's end users, it is found that no survey has ever been made to sufficiently explain marine transportation of coal. It is now expected that the gap between supply of and demand for shipping tonnage will widen thanks to a sharp increase supposed to emerge in the demand for overseas coal in the future and that a scarcity of tonnage will impede stable space securing for coal and economically viable coal transportation. Such being the case, this project aims to investigate the ocean freight systems to serve between overseas coal shipping ports and Japan's coal receiving bases and the current states and problems of cargo facilities in Japan, to study how to build up a shipping space securing system which will properly deal with an increase in the import of steam coal from abroad, and to contribute to the formation of measures for enabling smooth transportation of coal from overseas. The survey conducted for this purpose covers the present conditions of Japan's ocean freight systems and of its coal receiving bases, present conditions of transportation by oceangoing ships in the Pacific basin, compilation of a list of oceangoing ships, prediction of ocean freight transportation and supply of transportation service, prediction of ocean freight cost in the future, and putting in an easy-to-review order the tasks to be accomplished for the enhancement of coal transportation by oceangoing ships.

    This report dealt with the background of energy policies in E.U. countries and energy plans. At COP3, E.U. countries internationally gave a pledge that they will reduce the emission of greenhouse effect gas 8% from that as of 1990 during 2008-2012, which is stricter than those given by Japan and the U.S. Actually, the European Commission made public 'Toward the European Climate Change Programme' and 'Green Paper on Emissions Trading in the E.U.' These are correspondent to E.U.' global warming preventive strategy which is called the twin track approach by the European Commission. The former is a frame for coordinating individual reduction measures taken under the responsibility of member countries as the whole E.U. As to the latter, for the specified sectors from energy supply sectors to large energy consumption industries, it was planned to be started in 2005. And, the basic policy on the trade and concrete subjects/problems on the trading system were arranged. (NEDO)

    A simulation study was done to identify the causes for the so-called heavy damage belt observed as a result of the Hyogoken Nanbu Earthquake. This study determines distributions of the maximum amplitudes on the ground surfaces, and discusses the effects of deep structures and low-velocity surface layers, based on the simulation by the wave equation with the underground model of Higashinada-ku and its vicinity in the north-south direction, observed seismic records and artificial waves. The two-dimensional scalar wave equation is used for the analysis. The velocity structure model used for the simulation is established, based on the elastic wave seismic survey results. The focus function is drawn by expanding or contracting the time scale, using the seismic records at Kobe Port Island and artificial waves. The analysis results show that the damage belt coincides with the areas at which the focusing zone of the deep structure overlap the amplification zone in the low-velocity ground surfaces, where relative density is amplified 1.5 to 2 times. It is also observed that large peaks repeat 2 to 3 times on the time scale. 5 refs., 8 figs., 1 tab.

    For the improvement of quality of data collected by reflection aided seismic exploration using dynamite as the seismic source, information has to be collected about the surface layer structure before the charge depth is determined. For this purpose, refraction, electric, and electromagnetic exploration methods were tried. In the refraction method, an impactor was used as the seismic source. In the records, the surface wave prevails because vibration was generated on the surface. Analysis was made by the use of the initial travel time tomography. In the electric exploration, a double pole array was used to measure resistivity. The measured data was subjected to a fully automatic inversion for analysis. As the result, it was disclosed that it was useful to know the deep-level structure directly by use of tomographic methods in refraction seismic exploration so as to find the optimum charge level. Furthermore, about the electric and electromagnetic exploration techniques, it was found that these methods can be applied making use of resistivity to the evaluation of groundwater saturation. 7 refs., 5 figs., 3 tabs.

    Reflection exploration of earthquakes was conducted in the continental shelf off the north-west Australia, and a report is made concerning the processing of the acquired data. A GI gun was used as the vibration source, and a wave quite similar to a pulse was generated. Hydrophones were arranged with group intervals of 12.5m, and high-resolution field data were acquired. An analog low cut filter was used to suppress the large-amplitude swell noise attributable to sea conditions. A digital filter was designed for the purpose of eliminating coherent noises from other survey ships. At the ultimate stage the f-k filter was applied to each of the shot records, and the effectiveness was verified. The traverse line was as long as 6700km and therefore the design window was set relatively long at 2.0-4.0s in the residual static correction phase. It was found that this setup is effective in improving the continuity of the reflection surface. 5 figs., 1 tab.

    A reflection elastic wave seismic survey was carried out as part of the emergency survey of active faults in relation with the Hyogo-ken Nanbu Earthquake. This paper presents an interim report on the survey covering a wide area with deep structure as the survey object. The paper mentions that processing the survey data has been nearly completed, and is in the stage of making analyses and interpretations of the result of the processing, and that the survey was an attempt of making a unified survey over land areas, shallow sea areas, and seas by setting twelve traverse lines in and around the epicenter region. The paper also introduces briefly what has been found on hypocenters used, vibration receivers, vibration intervals, and CPD intervals, and on shapes of faults, particularly the continuity (the relationship of the Ashiya fault, Koyo fault and Osaka bay fault with the above two faults, branching of the Osaka bay fault, faults between the Wada promontory fault, Awaji Island and the Osaka bay fault, the fault off the east coast at the central part of Awaji Island, the Shichiku fault on the west coast of Awaji Island, and the basement fault). Mention is given also on the basement structure chart of the Osaka bay prepared preliminarily for the purpose of reference. 2 figs.

    The result is reported of a TDEM method-based survey for oil exploration conducted in the Yoneyama district, Niigata Prefecture. The survey covered the southern part of the sedimentary basin in the prefecture, known for the poor quality of the seismic prospecting data that had been recorded. The purpose of the TDEM method-assisted survey was to probe the high-resistivity volcanic rock structure and low-resistivity sedimentary layer, and to know their details. The obtained data were subjected to interpretation by use of the 1D inversion method. A 4000m-deep level was subjected to interpretation, 34 data were inputted, and the early model consisted of 20 layers. As the result, it was found that there was a high-resistivity layer ranging from the ground surface down to a depth of approximately 500m, that a low-resistivity layer 2500-3000m in thickness lay thereunder, and that the lowest layer had a high resistivity of approximately 100 Ohm m. By comparing these data with the geological structure, structures were disclosed corresponding to the rock bed depth, Ukawa syncline, Ishiguro anticline, and Yoneyama mountain mass. 3 refs., 10 figs., 1 tab.

    An investigation was carried out on characteristics of concentration and load amount of water flowing out from a small watershed with an area of 205 ha which is utilized mostly for agriculture. The basin subjected to the investigation was a district with typical tableland topography in Dejima Village in Ibaraki Prefecture. The land on this tableland in the district is utilized mainly for a truck farm, raising mainly vegetables and fruit trees. However, dry rice fields, which were converted from the truck farms into irrigated rice fields, exist on the tableland in this district. It is known that the dry rice fields have as high water permeability as inconceivable in ordinary paddy rice fields. Paddy fields developing below the tableland are called valley paddy fields, which are ill-drained paddy fields having small downward water permeation. It is an interesting subject to know what effects are given on the quality of runoff water by the topography in this watershed that has such a specific topographical chain as described. Furthermore, the dry rice fields are irrigated from the Dejima water canal taking water from Kasumigaura Lake, whereas large effects are anticipated on the amounts of runoff water and load because of such a large water permeation amount. This paper discusses the characteristics in amounts of runoff water and load in such a watershed as described. 20 refs., 17 figs., 2 tabs.

    A survey is conducted about highly automated machines such as industrial robots. The task to be subjected to development as derived from a survey conducted about needs is the construction of a dangerous work robot. It is pointed out that work in coal mines, tall buildings, industrial complexes, or nuclear power plants may encounter large-scale accidents, and the task is how to perform such work in an automated way. The tasks concluded to be subjected to development after a seed survey analysis are categorized into three groups of element technologies, namely, sensors and recognition function, mechanism and materials, and control and data processing. These element technologies are to be ultimately integrated into a robot, for critical work which is a combination of a highly intelligent robot main body and an integrated management system. Since it will happen that humans have to directly operate such a robot under delicate conditions and share the burden of judgement and thinking, it is also necessary to develop technologies to solve problems of man-to-robot engineering. It is proposed that a dangerous work robot research and development program be established before development is started. (NEDO)

    The effect on the marine environment in the bay when a Mega-Float is installed in a bay was investigated. The physical process such as a residual flow (including tidal currents, water temperature, salt, density, and density currents), and the ecosystem model for which floating organic matter and plankton are handled were incorporated to develop a program for water quality calculation in a bay. The program was used for Tokyo Bay and compared with the conventional calculation result and the oceanograhpic observation result. Simultaneously, the effect on the Mega-Float was considered. On the flow in Tokyo Bay in summer, the calculation result that comparatively coincided with the observation value in a residual flow level was obtained. The horizontal distribution of COD comparatively coincides with the existing observation result. The influence that the Mega-Float exerts on the flow, water temperature, water quality, and ecosystem in the ambient sea area was little and local in the calculation scale (L {times} B {times} d = 6 km {times} 3 km {times} 2 m) of this time. However, the difference occurring due to the design position must also be investigated in future. 12 refs., 8 figs., 5 tabs.

At COP3, E.U. countries internationally gave a pledge that they will reduce the emission of greenhouse effect gas 8% from that as of 1990 during 2008-2012, which is stricter than those given by Japan and the U.S. Actually, the European Commission made public 'Toward the European Climate Change Programme' and 'Green Paper on Emissions Trading in the E.U.' These are correspondent to E.U.' global warming preventive strategy which is called the twin track approach by the European Commission. The former is a frame for coordinating individual reduction measures taken under the responsibility of member countries as the whole E.U. As to the latter, for the specified sectors from energy supply sectors to large energy consumption industries, it was planned to be started in 2005. And, the basic policy on the trade and concrete subjects/problems on the trading system were arranged. (NEDO)

    `Eco-vendor`, an energy-saving type automatic vending machine for beverages with a peak cut function has been developed in 1995 through cooperation by Tokyo Electric Power Company, Coca-Cola Japan, and Fuji Electric Co., Ltd. It can cut 90 percent of the power consumption during 13:00 to 16:00 on weekdays in summer, and can save 10 to 15 percent of annual power consumption. Since the heat insulation performance has been improved to keep beverages at the set temperature during the peak cut operation, the energy-saving effect for cold products in summer and for hot products in winter has been enhanced. For the manufacturing of `Eco-vendor`, Fuji Electric Co., Ltd. has offered its technical know-how to five manufacturers of automatic vending machine for beverages without compensation, and each manufacturer has accepted the offer. Electric power companies of Japan have cooperated to pay incident of 10,000 yen per an `Eco-vendor` to the manufacturers. Japan`s automatic vending machine industries and nationwide beverage industries have positively cooperated. Consequently, Tokyo Electric Power Company has successfully spread 2,600 machines up to the end of fiscal 1995, and aims at the spread of 16,000 machines in fiscal 1996. 2 figs.

This equipment go by chapping a current in high frequency, so secondarily generates electromagnetic noise. The characteristics and propagation of electromagnetic noise generated by an elevator machine were measured. From this, it was recognized that high-level spectrum was included in the frequencies under 100kHz, and electromagnetic noise was scattered a wide area on the roof and the highest floor of the building. By intercepting the conductive noise on the motor main distribution line, the area influenced by the noise was restricted to only a small area around the elevator machine room. 4 refs., 8 figs., 2 tabs.

    The control system for keeping the fixed-point of ships against disturbance was designed by applying an ILQ (Inverse Linear Quadratic) control (possible to specify the response of controlled systems with time constant) theory, to study the effect of different time constants as design parameter on a fixed-point keeping performance. It was assumed that the controlled ship is equipped with two bow thrusters and one stern thruster of 30ton in output to generate a control force. For fixed-point keeping control, the state equation was derived to slave the controlled system to a target input. The ILQ design method uses the result of the inverse problem of optimum regulators. For designing control systems by using the ILQ control theory, the smallest time constant should be selected according to the most severe disturbance condition considering the response performance of controllers, to achieve fixed-point keeping of ships. In fixed-point keeping, it is also essential to put the initial position as close as possible to the target point. 2 refs., 6 figs., 2 tabs.

    This paper relates to the forecasting method of the electric power demands (kWh and kW) of a region, approached by not only time series analysis but economic and social indexes. Those indexes, based on historical statistics such as census and establishment statistics, are rearranged from an administrative division to a managerial division of the electric power company, and applied as fundamental information for forecasting the area`s kWh and also sales promotion. This method of forecasting the area`s kWh is based on the concept that area`s kWh is strongly connected with the population their lifestyle and their activity within the region. In the paper, the framework of the computational model system and forecast result are discussed. The population, number of households and their members, and number of employed persons, are all evaluated. The forecasting method of the area`s population proposed here is based on the concept that the transition of population consists of both natural growth and immigration. By estimating both factors, the future area`s population can be easily forecasted. The information of whether the population is increasing or decreasing is useful for forecasting the region`s kWh and required sales promotion. 8 refs., 8 figs., 3 tabs.

    A demand of coal shows the tendency in the increase worldwide, with this, the marine transportation of the coal gradually increases, and the collier has also enlarged. The traffic pattern of coal is mainly the bulk transportation. In this transportation system, by the oxidation exothermic reaction of the coal, methane gas is produced, simultaneously the coal quality such as coking property or heat quantity is decreased and sometimes spontaneous ignition is caused. Therefore, it is necessary to equip with a ventilator to control the concentration of methane gas and to avoid the self heating of the coal. In this study, the quantity of methane-gas produced by heating coal using an electric furnace was measured and the experiment to investigate the temperature dependency of the methane-gas generated from the coal was conducted. By using the result of the measurement, the quantity of methane-gas produced from the coal stored in the hold of a coal cargo was estimated. And, the mathematical analyses on the changing degree depend on the times of a temperature in the hold under navigation, a concentration of oxygen and a concentration of methane-gas, were conducted. 11 refs., 19 figs., 2 tabs.

    Cracks generated in coke layers during a coking furnace operation are an important factor not only to decide quality of the product, but also govern the energy consumption affecting the heat transfer and material transfer. This paper describes estimations of thermal stress and observations to fracture mechanics parameters, applying the incremental theory to surface cracks seen in the initial stage of carbonization. As a result of calculations using the crack tip opening displacement (CTOD) as a parameter to evaluate displacement in the vicinity of crack tips, the values increased with the increasing heating rate, and agreed qualitatively with the trend found in the experiments. The CTOD relates closely to the temperature dependence of the contraction coefficient, and varies largely at the transition point from the first maximum point to the second maximum point, from which the surface cracks are predicted to have been generated in this temperature region. Also, an estimation was made on the stress expansion coefficient from the stress distribution, and a result that can explain the experimental resultswas obtained. 10 refs., 11 figs.

    Fluidized bed as a coal combustion boiler has a practical application, but, there is not an example of which gas like helium as a cooling medium flow in a thin tube with diameter of 6 mm like a stirling engine and necessary data for selecting the medium of fluidized bed and estimating the heat transfer coefficient. Specially, it is difficult to correctly estimate the radiation effect concerned with the heat transfer coefficient in case of interposing the heat transfer tube at 800 [degree]C in the high-temperature fluidized bed at more than 900 [degree]C. Therefore, for investigating the thermal characteristics when the temperature of pipe itself is at high temperature, in the gas combustion fluidized bed in which alumina particle as fluidized medium is filled, the cooling tubes by using carbonic acid gas as a cooling medium was interposed, heat transfer coefficient was measured, radiation effect was clarified by experiment, and characteristics of the gas combustion and of the exhaust gas of fluidized bed when gas is used for a fuel was investigated. 13 refs., 12 figs., 1 tab.

    A single cell of molten carbonate fuel cell using a matrix electrolyte layer fabricated by using the doctor blade process has been operated for several thousand hours, measured of electrolyte loss amount, and analyzed by using a new electrolyte loss mechanism. The result may be summarized as follows: according to a result of measuring the matrix layer pore distribution, the average pore size has increased little by little; pores with diameters greater than 2 {mu}m at which no electrolyte retention becomes possible remain at nearly constant ratio up to 1800 hours, but increased after 2500 hours; the pore capacity in ports with the largest electrolyte retaining diameter of 2 {mu}m or less showed slight decrease with time in the anode, and an initial decrease followed by flatness, and then a sharp decrease after 1800 hours in the matrix layer; the electrolyte loss measurement values have remained nearly constant for 25 hours to 1800 hours, but increased sharply thereafter; and the electrolyte loss in this single cell due to pore capacity decrease in pores as power generating parts with diameters smaller than 2 {mu}m was explained quantitatively by a new electrolyte loss mechanism. 11 refs., 6 figs.

    Painting and cathodic protection are used in combination as a corrosion resisting measure for ship hull. n analytic method which uses the boundary element method for protection electric field by impressed-current method is proposed to show that rational determination is possible for the arrangement and current of the anode, and the arrangement and set voltage of the reference electrode used to control the current. However, repetitive calculation is necessary until overprotection voltage disappears from the surface of the painted steel plate while giving optional insulated area because the insulated area of adequate dimension is unknown. To decrease the number of this repetitive calculation, a study is made on a method of estimating the magnitude of the insulated area to be input as the initial value in the electric field analysis by the boundary element method. Although the insulated area has been empirically obtained, such formurization may be useful for automatic optimization using a computer of the location and number of anode, anode current, arrangement and set voltage of the reference electrode, magnitude of the insulated area, etc. in the impressed-current cathodic protection system. 2 refs., 10 figs., 1 tab.

    The Beijing Shuidian Research Institute of Geophysical Surveying has performed ocean seismic exploration in the area where the Fujian Pingtan bridge was planned to be constructed. The elastic wave exploration device is of a multi-functional type. The device has functions of acquiring, processing and analyzing data in seismic exploration using the reflection method, and can visualize subsurface conditions at the same time as performing the exploration. The planned bridge building area spans over a sea area of about 3500 m long with water depths from several meters to 30 meters. The foundation bed consists of dacite lithologic tuff and granodiorite. The seal level varies from 4.0 m to 4.8 m between high and low tides. According to the result of other measurements, the elastic wave propagation velocities of the sea water were found from 1475 to 1485 m/s, and the elastic wave propagation velocities at the surface bed of the sea bottom were from 1550 to 1700 m/s. The exploration used a workboat which moves at a constant speed while maintaining the offset between a transmitting source and a receiving source constant, executing vibration transmitting, receiving and recording all on the sea. The result of the exploration revealed that neither obstacles such as sunken ships nor marks of occurrence of ocean bottom landslides were present. 1 ref., 5 figs.

    Wide-range MT (magnetotelluric) observation is conducted to collect knowledge of the middle and lower parts of the crust of the above-named region, about which but a little information is available, for comparison with information about Kurile islands arc tectonics. Three traverse lines crossing the Kurile islands roughly in the north-south direction and two lines running from east to west are used, with the observation stations totalling 48. The distance between observation stations is 7-8km on the Nijibetsu line, and approximately 15km on the Nakashibetsu and Akan lines. A very wide frequency range of 320-0.0005Hz is used for measuring, and these results in detection with success of resistivity structure details from shallow to deep layers in the crust. The collected data are analyzed, and it is estimated that the northern and central parts have a high-low-high three-layer structure while the southern part has a low-high two-layer structure. Since the data obtained at observation stations at the middle of the lines, in particular, have an extremely low apparent value of several ohm/m at about 1Kz in the absence of splits in the TM (transverse magnetic) and TE (transverse electric) modes, it is inferred that the low-resistivity layer is considerably thick and is distributed rather uniformly. 13 refs., 5 figs.

The resultant engine characteristics were compared with the model characteristics of numerically analyzing a mathematical simulation model, and corrected to develop a high-accuracy simulation model. An element model and a dynamics model were prepared in detail on the main engine components, such as fans, a compressor, a combustor, and a turbine, along a flow diagram from the air intake opening to the exhaust nozzle. The pulses were inputted into the fuel supply by opening and closing an electromagnetic valve. Closing of the illustrated electromagnetic valve for about 0.7 second caused a difference (of phase and trend) in both characteristics of high and low frequencies as a result of pulse-like change in the flow rate. To correct the model characteristics, the combustion delay tie was set to 0.02 second upon considering the combustion delay time relative to the heat capacity of the combustor. Improvement in the model was verified as the phase characteristics was approximated to the engine characteristics. 13 refs., 17 figs., 2 tabs.

    With an objective to apply waste tires to asphalt pavement, an experiment was carried out to improve adhesion of asphalt with rubber particles by using polymers. The state of interface on rubber particle and asphalt mixture was observed by a scanning electron microscope. As a result, it was found that the surface of untreated rubber particles is not bonded with the asphalt, but polymer treated mixture was found to have the affinity of rubber particles with asphalt improved. Tensile bonding strength was tested on rubber plates and asphalt. The result revealed that the polymer-reformed mixture has two times as large tensile bonding strength as that of the untreated mixture. With regard to the characters of asphalt mixture mixed with rubber particles, the stability shows a decreasing trend as compared with the standard asphalt concrete, but presents an excellent performance in wear. The fluidity resistance value is inferior to the standard, but not as great as presenting a problem under normal using environment, where its applicability as a road paving material was verified. 4 figs., 2 tabs.

    In promoting international collaboration research project, coordination of the patent system of each country which participants to the project belong to has broad implications in concluding the contract for the project. For example, in Japan, 100% of the patent belongs to the government for contrast or collaboration project with the government. While, in the USA, the patent developed by the private company belongs to the private company even for the contrast project. In Japan, the shared patent can not be transferred to the third party or implemented without agreement with the partner. While, in the USA, the shared patent can be transferred to the third party or implemented without agreement with the partner. Due to such a difference, some projects can not be established by ill coordination of intellectual property even when the meaning of the projects is well understood. In this survey, was investigated the outline of patent systems of major countries to study about what should well balanced treatment of intellectual property in international collaboration research project be in the future. 4 figs., 8 tabs.

    The hydroelastic response test was carried out in waves using an approximately 10m long large model, and the numerical analysis was done by the direct method, for a commercial-size (300m long) box-shaped floating structure with shallow draft. The scale ratio of the model is 1/30.8, and the minimum wave cycle is around 0.7s from wave-making capacity of the tank, which corresponds to 4 to 14s with the commercial-size structure. Elastic displacement and bending strain were measured. The calculated results by the direct method are in good agreement with the observed results. The fluid dynamic mutual interference effects between elements are weak in added mass but strong in damping force, indicating that the range of mutual interference is strongly related to rolling cycle in the range of mutual interference. Wave pressure on the floating structure bottom is high at the upper side of the wave, greatly damping towards the downside of the wave. However, response amplitude of elastic displacement tends to increase at the ends, both in upside and downside of the wave. For the floating structure studied, the 0 to 4th mode components are predominant in longitudinal waves, and the 6th or higher mode components are negligibly low. 21 refs., 15 figs., 2 tabs.

    The results of the overseas survey were summed up mostly of global warming prevention measures taken by the U.S. government and those by private companies. At COP3 in 1997, the U.S. gave a pledge internationally that they would reduce greenhouse effect gas emissions during 2008-2012 7% below from that in 1990. But the U.S. government seems hesitating to take concrete measures in regions. Hesitating, however, they are publicly making it a target to find how to eliminate a risk of global warming which is now a global problem in cooperation with other countries and international organizations. Concretely, programs are as follows: ranking of the energy consumption amount of household electric appliances, housing loan programs taking energy efficiency into account, preferential taxing system, incentive money system in case of using the substituting energy transportation program, waste management program, commendation of men of achievements and prize-winning, etc. (NEDO)

    A high-speed hydrofoil catamaran under development has such a structure that an independent cabin is mounted on catamaran hulls, the cabin is connected with the hulls by using four soft springs, and hydrofoils are attached to the front and rear of the cabin. The structural design conception was as follows: the self-weight of the cabin is supported by lifting power of the hydrofoils while the boat is cruising; longitudinal motions of the catamaran hulls are absorbed by soft spring struts to make the motions more difficult to be transmitted into the cabin; and vibration excited by engines rotating at high speeds, attached to rear of the catamaran hulls, is not transmitted directly to the cabin structurally. A towing experiment was carried out by using divided models of about 1/10 scale in counter waves and regular waves to investigate their vibration response characteristics in waves. Furthermore, an experimental boat made of aluminum alloy with about 1/3 scale of the design boat was attached with composite structural struts made of springs and rubber parts to perform cruising experiments on an actual sea area. As a result, it was found that vibration excited by main engines in the catamaran hulls is transmitted very little to the cabin. 2 refs., 10 figs., 1 tab.

    This paper describes the calculation method of 3-D underground structures in TDME method which measures only field components. Recently, FDTD method was developed as calculation method in time domain difference calculus, and the forward analysis accuracy of 3-D fields was rapidly improved. The survey results using a large-scale loop (600m{times}360m) were numerically analyzed by FDTD method. 16 measuring lines were prepared in both X and Y directions, and measuring points were prepared on intersection points of the measuring lines. Since signal current is staircase one, step and impulse responses of the ground were determined by calculating magnetic field and its time differentiation. The rectangular body (120m{times}120m{times}100m) of 0.2S/m in conductivity (5 ohm m in resistivity) was installed 160m under the ground as 3-D resistivity anomaly. The ground of 0.01S/m (100 ohm m) was assumed. Time variation in horizontal magnetic field vector plot of impulse responses of the uniform ground could be observed. The position of the resistivity anomaly could be also determined from spacial differentiation of magnetic field of grid pattern measuring points. 1 ref., 6 figs.

    Japan currently produces about six million tons of coal ash annually, whose effective bulk utilization to earth engineering materials is an important issue of technological development. A slurry may be made by mixing the following three kinds of materials: fly ash discharged from power plants exclusively burning dust coal (F), gypsum generated as a by-product in a stack gas desulfurizing process (G), and commercially available cement (C). The slurry would be called an FGC slurry taking the first letters of the materials. This paper presents the results of laboratory tests, in-situ execution tests and centrifuge model testing on engineering characteristics of soils improved by the FGC slurry when the slurry is applied to implementing the deep mixing method. As a result, a large number of findings were obtained including the following matters: the FGC deep mixing method makes it possible to improve ground beds having small deformation coefficient with the same accuracy as in the cement-based deep mixing (CDM) method at strengths lower than 5 kg/cm {sup 2} which is difficult with the CDM method, not to speak of strengths equivalent to that is possible with the normal CDM method; and development of a ground bed with improved strength is possible without being governed by quality and kinds of the fly ash. 1 ref., 23 figs., 5 tabs.

    Japan National Oil Corporation Technology Research Center has carried out experiments on the three-dimensional seismic survey method which is regarded as an effective means for petroleum exploration. The experiments were conducted at the Minami Noshiro area in Akita Prefecture. Seismometer arrays were developed in radii of 30 to 300 m at seven points in the three-dimensional seismic exploration region to observe microtremors. The purpose is to estimate S-wave velocities from the ground surface to the foundation by using surface waves included in microtremors. Estimation of the surface bed structure is also included in the purpose since this is indispensable in seismic exploration using the reflection method. This paper reports results of the microtremor observations and the estimation on S-wave velocities (microtremor exploration). One or two kinds of arrays with different sizes composed of seven observation points per area were developed to observe microtremors independently. The important point in the result obtained in the present experiments is that a low velocity bed suggesting existence of faults was estimated. It will be necessary to repeat experiments and observations in the future to verify whether this microtremor exploration method has that much of exploration capability. For the time being, however, interest is addressed to considerations on comparison with the result of 3D experiments using the reflection method. 4 refs., 7 figs.

    The chimney stack at the Wakayama power plant is planned to adopt a fiber reinforced plastics (FRP) inner cylinder having greater cost reduction effect than a steel made inner cylinder. The present study has performed different experiments on FRP under the gas emitting condition at the Wakayama power plant, and discussed structural plans based on the result therefrom. The Wakayama power plant has the waste gas raised in temperature because of difference in the power generation system. Therefore, physical constant verification tests and heat resistance tests were performed on FRP to verify its applicability. Structural discussions to pursue economy were given on the 'joints' and 'suspension points' (supporting points to suspend the FRP inner cylinder) being the major FRP structures based on the actual record at the Nanko power plant. The tests have placed focus on the 'heat resistance', and different experiments were carried out upon selecting two kinds of novolak-based vinyl ester resins. As a result, applicability of the FRP made inner cylinder to high waste gas temperatures was verified, and so were various property values to be used for designing the cylinder. Structural design was performed by applying design safety factor to the derived property values, and the basic structural plan was established for the FRP inner cylinder. (NEDO)

    The electric power demand in Japan is increasing, and it is expected that annual load factor shows decreasing tendency. All electric power companies endeavor to improve load leveling than as it was, and intend to introduce direct saving system to control the loading equipments of consumers as well as indirect control such as midnight power system. Therefore, quetionaire inquiry about this new system was made for business power consumers in which power there are much difference in consumed power between day and night and much efficacy for power saving. As the results of the inquiry, it was understood that equipment of automatic or remote control for loading equipments were already introduced by many consumers and adoption of airconditioners controlled at every floor or every room is increased. So, about the control of the equipments in cosumers a method is also required so that electric power companies shall control the maximum demand by consumers and selection of control equipments are left on consumers' decision and judgment, and it is considered to be important that control by electric power companies shall not only turn on or off switchs but also realize convenience and economy of consumers. 9 figs., 3 tabs.

    On the honeycomb type adsorptive concentrator, a manufacturing method of the honeycomb adsorbent rotor, retention of mechanical strength corresponding with a large-scale processing and minimization of air leakage resulting in performance deterioration were technically examined. Honeycomb structure was formed from an alumina-silica fiber paper, and high silica-content zeolite was deposited in the fiber void of the matrix. The adsorbent rotor using sepiolite as an inorganic adhesive for honeycomb fabrication showed fracture strength of from 1.6 to 3.2 times the conventional adsorbent rotor. Two types of differently shaped fluorinated rubber seal were developed for the adsorbent rotor. Amount of air leakage from the seal between each zone as well as to outside was sufficiently small. A large-scale VOC concentrator with the 3950 mm diameter and 450 mm length was manufactured with the adsorbent rotor and seal structure in accordance with the aforementioned method. Results of the real machine operation showed same concentration performance at those of the small-scale experiment. 10 refs., 15 figs., 2 tabs.

    Research study was made on the current usage, technological development and future subjects of biomass energy. The current use of biomass energy over the world estimated to be nearly a billion t/y oil equivalent. This value is estimated to be only a part of a pure primary biomass yield of 73 billion t/y oil equivalent showing a large supply potential. The evaluation result of a biomass energy potential in the world by GLUE (Global Land Use and Energy Model) considering worldwide biomass flow and competition of land use showed that no change of land use form in advanced areas is predicted, and no production of new biomass energy from forests in advancing areas is also expected. Production of biomass energy from farm products is promising in advanced areas, while the potential of biomass residue is high in advancing areas showing the possibility of energy development. Development of new biotechnologies such as molecular control of bio-production functions is expected to increase biomass resources. 76 refs., 26 figs., 30 tabs.

    When a general view is taken of coal chains that connect overseas coal suppliers to Japan's end users, it is found that no survey has ever been made to sufficiently explain marine transportation of coal. It is now expected that the gap between supply of and demand for shipping tonnage will widen thanks to a sharp increase supposed to emerge in the demand for overseas coal in the future and that a scarcity of tonnage will impede stable space securing for coal and economically viable coal transportation. Such being the case, this project aims to investigate the ocean freight systems to serve between overseas coal shipping ports and Japan's coal receiving bases and the current states and problems of cargo facilities in Japan, to study how to build up a shipping space securing system which will properly deal with an increase in the import of steam coal from abroad, and to contribute to the formation of measures for enabling smooth transportation of coal from overseas. The survey conducted for this purpose covers the present conditions of Japan's ocean freight systems and of its coal receiving bases, present conditions of transportation by oceangoing ships in the Pacific basin, compilation of a list of oceangoing ships, prediction of ocean freight transportation and supply of transportation service, prediction of ocean freight cost in the future, and putting in an easy-to-review order the tasks to be accomplished for the enhancement of coal transportation by oceangoing ships.

    For two 400kW wind turbines erected in Jan. 1996 of Yamagata Wind Energy Institute, their estimated power output was compared with actual output for 7 months. AMeDAS data in 1985-94 were totaled every month to use as basic data. The altitude and surface roughness model necessary for WAsP analysis recommended by NEDO`s wind condition close inspection manual were prepared using 1/25,000 maps and aerial photographs. The obstacle model for estimating wind conditions at height of the wind turbine was prepared using the data obtained by field survey. Mean wind velocity and latent energy were determined by statistical analysis of wind velocity occurrence relative frequencies and Weibull distribution parameters. The power output of 717,700kWh was obtained for 7 months, which is equivalent to 88.5% of the estimated output of 810,730kWh for the same period. It was clarified from obtained characteristic wind conditions at the site that the wind power generation is promising at the site not only in winter but also in summer. Although the test period was too short, this method was effective as analytical method of output estimation in the planning stage of wind turbines. 3 refs., 8 figs., 4 tabs.

    The tank system and tank-less system when the temperature selective heat storage tank is applied to a solar system were considered. In the tank system, the simulation shows that the annual supplementary heat consumption is reduced as the tank capacity becomes lower. The most suitable operating time set for determining the reference time is about five hours in winter and about nine hours in summer. The annual operating time is about 6.5 hours. In the tank-less system, the most suitable minimum flow rate per solar collector area of a heating medium in Tokyo and its districts is 10 L/hm{sup 2} for both three-step flow control and constant flow control. The tank-less system is slightly lower in annual supplementary heat consumption than the tank system. For the three-step flow control, a change in the annual supplementary heat consumption is lower than that in the minimum flow rate. For the constant flow control, however, the annual supplementary heat consumption rapidly increases when the flow rate more decreases than the optimum value. The number of pump start/stop counts for the three-step flow control is less than two times as high as for the constant flow control. 4 refs., 6 figs., 1 tab.

    Tethering cable was investigated as a part of a research of jet stream power generation using balloon and kite. Recently, there appeared new materials with light and high strength properties, such as carbon and polyamide resin. When these are used as tethering cables, flying ability of tethered bodies is remarkably improved. Tethered balloon at the altitude of 6500 feet and large-scale kite at the altitude of 5000 m are proposed for the idea of jet stream power generation. A computer program was developed for determining the flying ability of a kite, to calculate it. Similarity rule was also determined by the dimensional analysis. For a kite with a tethering cable having uniform diameter and specific gravity, the similarity can be obtained when two kinds of similarity rules are satisfied. One is (length of tethering cable/width of kite wing)times(dynamic pressure of air/tensile strength of cable){sup 1/2}=(constant). Another is (length of tethering cable)times(density of cable/tensile strength of cable)=(constant). Since the maximum height is in proportion to (strength/specific gravity) of the cable, it increases drastically using high performance materials. It is affected by the aerodynamic performance of the kite and the safety factor of strength of the cable. 4 refs., 45 figs., 2 tabs.

    Concerning the smooth surface and dimpled surface cables, experiments were conducted to investigate relationship between their wake galloping characteristics and aerostatic force characteristics they demonstrate when exposed to wind blowing in a skewed direction. The wind tunnel used for the experiment was a closed type measuring wind tunnel, 2.0m wide, 2.5m high, and 15.0m long. In the wind tunnel, two cables were arranged with the distance between the cable centers three times as large as the cable diameter D, and with relative vertical difference of 0.25-0.50D, and spring-supported experiments for evaluating wake galloping characteristics and aerostatic force coefficient determining experiments were carried out. It was deemed as the result that turbulence exerts influence on the wake galloping characteristics of the dimpled surface cable more than on those of the smooth surface cable, that on a real bridge the effect of turbulence may be expected in case of exposure to natural wind of turbulence with intensity higher than 5-7%, and that therefore application of some damping by dampers will adequately damp wake galloping even in case of the 0.37D vertical difference. 12 refs., 23 figs.

    This paper discusses how to promote international lateral work sharing and how to strengthen infrastructures in the petroleum industry, as a problem prevailing over the petroleum refining facilities in Japan. Excess distillation facilities have been applied with the disposition policy. However, in view of the supply and demand situation in petroleum products for medium to long term span in the world with the pan-Pacific region as the main concern, that applicable to Japan, and that experienced during the Persian Gulf crisis, the excess facility disposition policy was revised, particularly on white kerosene, of which supply and demand tightness is concerned about, so that production capacities may be increased as required. Japan, a large presence in the international economics, is required to work more positively on petroleum refining facilities located in the oil producing countries and intermediate locations to promote the international lateral work sharing. On the one hand, in order to strengthen the infrastructures in the Japanese petroleum industry, it is necessary to promote rationalization and use at higher efficiency of the oil supply system, and convergence of the the petroleum industry, including joint investments for projects exceeding capabilities of individual enterprises. 3 tabs.

    To evaluate feasibility and accuracy of intraocular pressure (IOP) measurement by rebound tonometry in adult red-eared slider turtles and determine the effects of manual and chemical restraint on IOP. Seventeen adult red-eared slider turtles. Intraocular pressure was measured with TonoLab® and TonoVet® tonometers in conscious, unrestrained turtles. To evaluate the effects of manual restraint, turtles were restrained by digital pressure on the rostral head or proximal neck. The effect of two chemical restraint protocols (dexmedetomidine, ketamine, midazolam [DKM] and dexmedetomidine, ketamine [DK] subcutaneously) on IOP was evaluated. Triplicate TonoLab® and TonoVet® readings were compared with direct manometry in three ex vivo turtle eyes. TonoLab® correlated better with manometry at IOPs < 45 mmHg than TonoVet® (linear regression slopes of 0.89 and 0.30, respectively). Mean (±SD) IOP in unrestrained conscious turtles was significantly lower (P < 0.01) with TonoLab® (10.02 ± 0.66 mmHg) than with TonoVet® (11.32 ± 1.57 mmHg). Manual neck restraint caused a significant increase in IOP (+6.31 ± 5.59 mmHg), while manual rostral head restraint did not. Both chemical restraint protocols significantly reduced IOP (DKM: −1.0 ± 0.76 mmHg; DK: −1.79 ± 1.17) compared with measurements in conscious unrestrained turtles. Chemical and manual neck restraint affected IOP. Rostral head restraint had no significant effect on IOP and is, therefore, recommended as the appropriate restraint technique in red-eared slider turtles. TonoLab® measurements estimated actual IOP more accurately, within physiologic range, than measurements obtained using the TonoVet®. © 2013 American College of Veterinary Ophthalmologists.

    It is intended to research and develop a system for mining manganese nodules existing on deep ocean bottoms by using the fluid dredging system. A mining experimenting system will be developed, and fabricated on a trial basis to perform comprehensive ocean experiments, identify its performance, and collect different design data for a system to be used practically in the future. Fiscal 1991 has performed the following items: (1) detailed design on a comprehensive ocean experimenting device, and fabrication of part of the device, (2) preparation of experiment execution procedures for the comprehensive ocean experiment plan, and surveys on the experimenting ocean areas, (3) the comprehensive experiment simulation on behavior of the mine collecting device when settled on the ocean bottom, and strength of the ore lifting pipe considering safety, and (4) discussions on the basic plan for the mining system. The system under the research and development in progress is a system combining ore collection by water flow blow-up and suction, ore lifting by using a fluid dredge, and device towing. The ore collecting efficiency is defined as (nodule take-in quantity)/(take-in area in existence), whereas the water flow blow-up and suction system has greater advantage because of being simple in device configuration. The supply efficiency is defined as (nodule supply quantity to ore lifting device)/(nodule take-in quantity). Combination of the ore collection using the water flow blow-up and suction system with the ore lifting using the fluid dredge is a best selection. (NEDO)

    With an objective of using practically the coal hydrogasification technology (the ARCH process), developmental research has been performed on important elementary technologies using different experimental devices. This paper summarizes the achievements in fiscal 1999. In the research by using a small testing apparatus, the Taiheiyo coal was used to have performed demonstration operation on the replacement natural maximized case, the heat efficiency maximized case, and the BTX maximized case. As a result, the three cases were found nearly as anticipated in the simulation, whereas the replacement natural gas maximized case has achieved the targeted whole coal conversion rate of 60% or more. However, the BTX maximized case presented a value lower than the targeted BTX yield of 12%. In the developmental research on the injector, the injector having been fabricated for the hot model test was given another combustion test, where the focal temperature of 1,200 degree C or higher was derived. The hot model test has verified the non-agglomeration performance of coal by using as parameters the focal temperatures, coal cross sectional area loads, coal types, and injectors. It was verified that the Taiheiyo and Shin Mu coals do not agglomerate excessively. (NEDO)

    The operation continues of the experimental device capable of producing 10 tons/year of SOG (spun on glass)-Si, and efforts are under way to carry out improvements, to verify such improvements for the results, and to develop operation control technologies. During the operation, improvements are made with respect to the length of stable operation period, granule quality, and device operation, and the results are verified. An automated control test system is verified, and a reactor tube newly developed by Shin-Etsu Chemical Company is subjected to a durability verification test. On the other hand, development is started of SiC-CVD (chemical vapor deposition) technology for materials for large reactor tubes, studies are started on a basic experimental device, basic studies are conducted for designing a large reactor, and investigations are conducted of a large plant conceptual design, an automated control system for reactors, and so forth. The results achieved are all found to be satisfactory. Above all, the granule quality is improved to be quite high in purity, and a cast cell made from improved granules exhibits a photoelectric conversion efficiency to exceed 13%. It is also found that the newly developed reactor tube is stronger than conventional reactor tubes and will be advantageous over others in the future enlargement of devices. (NEDO)

    The aim is to develop a fluidized bed reactor high in productivity and low in power consumption for the realization of mass production of low cost polycrystalline silicon usable for solar cell construction. An experimental device capable of producing 10 tons/year of SOG (spun on glass)-Si is built and operated. The fluidized bed reactor treating trichlorosilane as the material and the product quality achieve the initially set goals, and the essence is seized of operation management technology. In fiscal 1986, for development of the technology into a practical application technology, designs are prepared for a larger reactor unit and a large plant of the commercial scale. From the viewpoints of production efficiency and cost, the enlargement of a reactor unit is an inevitable task to discharge before practical application. There are two challenges to meet. One is the development of technologies for manufacturing large reactor tubes strong enough to withstand practical service and the other the development of a reactor structure fit for dimensional enlargement. It is then found that the concept of an economically optimum design relative to device series or device block formation is variable in the case of large plants, dependent on the scale of production, and that therefore it is necessary to arrange problems in a proper order to facilitate further deliberation.

    In connection with the R and D of a deep sea bottom manganese nodule mining system, the results were summarized for the total system (experimental system) carried out in fiscal 1991. In the experimental system operation section, adjustment and examination were made on the issues and problems concerning design and manufacturing over each sub system continuously from the previous year, with the detailed design of the entire experimental system compounded. In addition, as an oceanic general experimental plan, consistency was confirmed between the development of the detailed design of the experimental system and the conditions of the area of the sea where the experiment was to be performed, with the points looked over for the implementation of the experiment, and with the behavior examined of the mining machine at the time of landing on the sea bottom in the general experiment simulation. Further, taking it into consideration that the boat for the mining experiment was a type of boat for oil rig and that its steering was dependent on towing by a tugboat, examination was started on the boat steering simulation at the time of tug towing. Furthermore, detailed design was started for the experiment system on the basis of the oil rig, with examination made on the principal particulars, weight, center of gravity, etc.. (NEDO)

    The electrical stimulation of the auditory nerve can elicit auditory sensations in the subjects with sensorineural deafness. Each stimulating electrode of an electrode array of the multi-channel cochlear implants may stimulate a distinct neural population. However, a great deal of current spreads from each electrode throughout a lymph because of the high electrical conductivity of the lymph liquid. This phenomenon causes the transmitted information to be reduce due to channel interactions. Even if the number of electrodes is increased, the transmitted information will be limited because of current spread. We have proposed the Tripolar Electrode Stimulation Method (TESM) which may succeed in narrowing the stimulation region and continuously moving the stimulation site for the cochlear implants. We evaluate whether or not TESM works according to a theory which is based on the numerical analysis using the auditory nerve fiber model consisted of unmyelinated and myelinated segments. In this simulation, the neural site and the am of the excited fibers are compared with the compound action potentials which we obtained through animal experiments. As a result, based on the numerical analysis using this model, it is also proved that the anodal/cathodal threshold stimulation current ratio increases by decreasing unmyelinated segment between the inner hair cell and the habenula perforate. Also by comparing the result of the numerical analysis with that of the animal experiment, It is suggested that an effect of the unmyelinated segment is not significant. Based on their results mentioned above, we succeed in narrowing a Stimulation region by controlling the am of the currents emitted from the electrodes on both sides. Also we succeed in continuously moving a stimulation site by changing the ratio of the currents emitted from the electrodes on both sides. 11 refs., 14 figs., 1 tab.

    For the purpose of securing the stable supply of non-ferrous metal resources such as Ni, Co, Cu and Mn and of improving the overall ocean development technology, the R and D were carried out of a technology to mine Mn nodules existing in the bottom of deep sea of the depth between 4,000m and 6,000m by the fluid dredging method which is highly efficient and reliable. Therefore, plans of experiments to be made for each subsystem are adjusted/integrated to make the contents of a comprehensive experiment, and at the same time a draft of the comprehensive experiment plan was worked out for an experimental system to be developed/trially fabricated. As to a total system (experimental plan), a plan for execution was studied in the case of rationalizing the comprehensive ocean experiment plan and choosing between pump lift and air lift. The TA-C sea area was continuously investigated as a candidate sea area for survey and the range was limited. The paper studied the basic plan of the mining system and commenced the basic study of the assessment of economical efficiency. (NEDO)

    In this study, the stability of annular leakage-flow-induced vibrations was investigated theoretically and experimentally for a translationally and rotationally coupled two-degree-of-freedom system. The critical flow rate was both theoretically and experimentally obtained as a function of the passage increment ratio and the eccentricity of the passage. A good agreement between the theoretical and experimental results was obtained. It was discovered both theoretically and from the experiments that instability will occur in the case of a divergent passage: the eccentricity of the passage lowers the stability of the systems.

    With an objective of using practically the coal hydrogasification technology (the ARCH process), developmental research has been performed. This paper summarizes the achievements in fiscal 1997. In the research by using a small testing device, the Taiheiyo coal was used to have derived hydrogasification data (distribution and yield of the reaction products) in case of having changed the temperature, residential time and H{sub 2}/caoal ratio at a pressure of 7.0 MPa. In the developmental research on the injector, a test to verify mixing performance was performed by simulating the coal/hydrogen with gas/gas and coal/gas at normal temperature and pressure. Furthermore, discussions were given on the heat conduction analysis and cooling structure, whereas an injector was designed and fabricated. With respect to the hot model test to verify the performance of the injector, detailed design and partial fabrication of the test device were carried out. In addition, development was conducted on the coal/gas system mixing simulation to simulate the states of dispersion and mixing of the coal as the first phase of developing the mixing and temperature rise simulation.

    Studies are conducted to enlarge the diameter of polycrystalline Si castings and to develop a low-loss slicing method using silicon nitride powder as mold releasing agent. The apparatus for Czochralski's pulling process is improved and tested using SEG (selective epitaxial growth) Si, and now the casting of a 150mm-diameter ingot is feasible. Also, test production of a 94mm-square wafer as specified by NEDO (New Energy and Industrial Technology Development Organization) is successfully carried out. Difficulties in separating the mold releasing agent from the crucible are solved by changing the Si{sub 3}N{sub 4} power solution from PVA (polyvinyl alcohol) to ethyl silicate. The design, manufacture, and installation of the important parts of the system for the mass production of castings are now complete. The crucible is designed to be movable relative to the heater section, and the molten Si is allowed to cool and solidify from the bottom upward. In relation with the development of low-cost wafer manufacturing technologies, low-loss slicing methods are studied. It is concluded that under the current circumstances a multi-blade saw is more promising than the multi-wire saw in view of the damaged slice rate, processing speed, operating cost, and maintainability.

Before the construction of this 2.4T/day-capable research plant, its details were designed in fiscal 1979 when the plan placed the plant at the Chiba establishment of the Mitsui Engineering and Shipbuilding Co., Ltd. The plan was altered in July of fiscal 1980 for the plant to be built at the Keihin steelworks site of the NKK Corporation, and then partial modification was implemented for the basic and detailed designs of the plant for the second year running. Furthermore, a review was made so that the results of the element studies that followed the designing of the details would be embodied, and the changes were reflected on orders placed for equipment and construction work. These processes culminated in the 2.4T/day-capable research plant, now complete and subjected to inspections by the relevant Government offices. In a study of the operation of the plant, an operating procedure is worked out, and water-handling tests are conducted for each of the stages of operation. The plant will be subjected to a full test operation, improved as required, studied for proper operation, and will undergo additional construction work as required, all these in preparation for a continuous operation in the future.

    Natural convection heat transfer and flow structure in an anisotropic porous medium of square cavity saturated with Boussinesq fluid has been studied experimentally using a Hele-Shaw cell. The permeability ratio defined by K=K{sub y}/K{sub x} was put to three different values; 0.4, 1 and 2.5. The convection patterns at three different permeability ratios are visualized for several different Rayleigh numbers by the pH indicator method. When K is 0.25, the visualized flow is mainly in the vertical direction. On the contrary for K=4 the convecting flow is in the horizontal direction. The average heat transfer coefficients are also measured, and the corresponding Nusselt number are plotted as a function of K. It is found that the corresponding Nusselt numbers are scaled with (KRa){sup 1/2}. The experimental results of flow pattern and heat transfer are accord with those obtained by our previous theory.

    This program is aimed at establishing the techniques for solvent-extraction type coal liquefaction plant by constructing and operating a 1 T/D test plant to obtain the technical data for the efficient plant. The test plant is operated to confirm the effects of temperature and coal slurry concentration on liquefaction conversion by the solvent-extraction for a short time in the furnace for the extraction unit. The extraction type coal liquefaction tests can be conducted for a reaction time of around 1 hour by the test plant. The recycled solvent purification unit is installed, to regenerate the hydrogen donor solvent. For researches on the solvent-extraction type coal liquefaction process, the continuous extraction is conducted, to investigate the effects of extraction reaction rate at relatively low pressure. The optimum hydrogenation conditions are studied for the test plant. It is confirmed that a Mo-based catalyst is suitable for the hydrogenation. The batch type reaction system is operated to investigate the liquid yield of Wandoan coal, and recycled solvent balances and compositions. (NEDO)

    The effort aims to develop a reactor and its peripheral devices and process management technology therefor and to develop chlorosilane hydrogen-reduction process technology as part of the endeavors to develop a low cost production process for silicon for photovoltaic cells for the purpose of building a model plant capable of approximately 10 tons/year in terms of SOG (spin on glass) silicon. The installation of a 10 tons/year class model plant for SOG-Si production is completed in July 1982. Flaws are removed after a test run, and four reactions are accomplished without damage on the reactor tube in the period from February-end to March-beginning marking 550 hours of operation in total. Thanks to the four operations, 1,086kg of granules are experimentally produced and an electric power consumption rate of 30.6KWH/kg Si is achieved, control of the flowing particle amount by reactor differential pressure is accomplished and the same of the yield by recovered silane liquid composition analysis, and essence is seized of operation control technologies. In an experimental apparatus for seed production, Si is crushed by a roll crusher and then subjected to separation by a quartz-made air elutriator. A high yield of 130kg is obtained after crushing for 75 hours. (NEDO)

A study is made of ten operations (total reaction time of 2,264 hours), and it turns out that the electric power consumption efficiency is near the initially planned value. The yield of Si is, however, but 16.5% which is lower than the initially planned value of 20%. The value is elevated to 18% by raising the reactor temperature. To prevent overcleaning, a reactor with its internal walls experimentally coated with SiC is tested. The problems with devices other than the reactor tube are extraction rendered difficult by anomalously grown granules and processing devices choked by Si powder contained in waste gas after reaction. The first problem is settled by modifying the extraction tube but the other still needs a remedy. The produced granules are found to be high in quality. The seed producing roll crusher is operated for a total of 92 hours yielding 857kg in total. (NEDO)

    Steel structures in sea water and surface of hulls are deposited with such marine organisms as microorganisms, algae and shellfish. The deposition causes a large problem such as occurrence of abnormal local corrosion in the structures, and increase in cruising resistance in ocean vessels. The present study has introduced a simplified equation of estimation for current and potential distribution in parts coated with an electrically conductive film, and verified its reasonability by an experiment. The equation of estimation was introduced by following a model of current flow in the electrically conductive coating. The experiment has the conductive coating applied to the interior of a concrete water tank with a length of 10.8 m, a width of 5 m and a depth of 3 m to measure potential at different locations. The conductive coating was energized from copper foils attached on each applied face, whereas the current was applied to two faces between the conductive films as a pair among the four coating applied faces to measure potential in each location. A simulated calculation revealed that the potential range in the depth direction is made smaller if specific resistance of the conductive film is decreased, and made greater if increased. Effectiveness of the equation of estimation was verified by an experiment. This method has provided a prospect of achieving optimization of the specification for application of the conductive film. 2 refs., 7 figs.

    In fiscal 1984, studies are conducted for long-time stabilized operation of the device (extension of reactor tube service life, elimination of flaws in the granule extraction process, control of deposited silicon), improved granule quality (measures to deal with Cu pollution), cost reduction (improvement on yield of silicon after reaction, reduction in electric power consumption rate), and so forth. The results are found to be satisfactory in outline. The problem of strengthening the reactor tube material itself remains to be solved, however, with many knotty issues to settle before practical application. In the effort to deliberate these difficulties, as many as 4,377 hours (reaction hours) in total are spent in fiscal 1984. During the operation, 8.3 tons of granules are produced of which approximately 7 tons are fed to the next stage of processing. The quality of granules produced in this way is stable thanks to efforts to prevent pollution and to prolong continuous reaction time, and is found to satisfy NEDO (New Energy and Industrial Technology Development Organization) specifications. Furthermore, the cast cell and the ribbon cell using thus-produced granules achieve photoelectric conversion rates of 10% and 9%, respectively, thereby meeting the target goal of 9%. (NEDO)

    This project is aimed at development of the fluid dredging type technologies for collecting manganese nodules on deep sea beds (4,000 to 6,000m deep), in order to secure stable supply of the non-ferrous metal resources and improve marine development technologies. The test sea area determined is the seamount JA-4 south of the Minami-Torishima Island. The test schedule preparation working group has drawn the draft test schedules; the phase 1 tests (including water lifting and towing tests) at the TA-GA area, a sea area with a relatively thick acoustic transparent layer, located on the east side of the center of the flat peak of the seamount, and phase 2 tests (including mineral lifting tests) at the TA-GB area, a terrace on the south-east side of the flat peak of the seamount, where seamount manganese nodules are massively occurring. The studies for preparing the test schedules are started, based on the drafts, and also the studies are implemented for the test implementation manuals, including those suitable for No.3 Hakuryu as the test vessel. The other items studied include the basic studies on the air lift system for collecting minerals on a commercial scale, and on economic evaluation. (NEDO)

    With an objective of using practically the coal hydrogasification technology (the ARCH process), developmental research has been performed on important elementary technologies using different experimental devices. This paper summarizes the achievements in fiscal 1998. In the research by using a small testing apparatus, the Taiheiyo coal was used to have derived hydrogasification data (distribution and yield of the reaction products) in case of having changed the reaction pressure, temperature rising rate, and H{sub 2}/caoal ratio, and to verify the possibility of increasing the BTX yield by installing a temperature zone in two steps. In the developmental research on the injector, a combustion test and a coal feeding test were performed on the injector having been designed and fabricated in the previous fiscal year to verify the basic performance and evaluate the heat resistance and durability. With respect to the hot model test, a test installation was completed with the injector mounted to conduct the trial operation and test. In addition, development was conducted on the coal temperature rise simulation as the second phase of developing the simulation of mixing of coal with high-temperature hydrogen and temperature rise.

    Since its construction in 1982, the experimental device capable of 10 tons/year production of SOG (spun on glass)-Si has been in operation, and the trichlorosilane processing fluidized bed reactor has achieved its goals in performance and product quality. Element studies continue for the enlargement of the reactor unit for practical application and for the designing of a large plant of the commercially viable scale. In fiscal 1987, element studies are conducted for the enlargement of the reactor unit. Concerning the development of technologies for the manufacture of large reactor tubes strong enough to withstand practical application, efforts are made to strengthen materials for the fabrication of reactor element tubes (230mm and 500mm in diameter), to develop SiC-CVD (chemical vapor deposition) technology to provide reactor tube materials with resistance to corrosion, and to develop a single reactor tube structure indispensable for device enlargement. For the verification of such element technologies, in line with the study of experimental device operation capable of 10 tons/year SOG-Si production, studies are conducted on continuous stable operation technologies for the fluidized bed reactor, maintenance and improvement of product quality, and enhancement of durability of constituent parts and components.

    This paper describes development of a penetrator intended of measuring temperatures, pressures, and particle velocities of air blasts and pyroclastic surges occurring in volcanos, and its airdropping experiment. This device forms a spear with a total length of 150 cm to 160 cm disposed with wings at the tail, and a stopper to prevent the spear from penetrating into ground deeper than 60 cm. The device for measuring temperatures suspends metal pieces of 16 kinds in total including such metals as lead and tin, and such alloys as eutectic solders and type lead to enable measuring a temperature range from 100[degree]C to 810[degree]C . The device for measuring pressures consists of a square pipe with a length little shorter than one meter, twisted to 22.5[degree] at three locations, each of the 16 faces made from the twisting being attached with two blast meters (using lead and copper foils, serving also as particle velocity meters). Twelve prototype devices have been dropped (not having been recovered yet) on five points of the east side slope of Mt. Unzen using a helicopter. 5 refs., 3 figs.

    Study was made of the energy conservation by reducing stand-by consumption power of household electric appliances. In the study, remote control, household electric appliance, and outlet box were developed, and a system was developed in which each of the three was connected by network and the commercial power source supply is cut off at the time of the stand-by state of household electric appliances. The outlet box collectively manages timer information and reservation information. User sends out control command toward the outlet box using the two-way remote control, and controls all the household electric appliances connected via network. The screen data of household electric appliances are sent to the two-way remote control via the outlet box and presented to user. When the time comes for automatic execution such as video recording during absence, the outlet box carries commercial power source to household electric appliances. Using these appliances, verification experiment was carried out in the model house which was built with the ordinary house as model. A reduction in stand-by consumption power, approximately 218kWh/year(center dot)household, was verified. (NEDO)

    To compare and evaluate the accuracy of intraocular pressure (IOP) measured through a therapeutic contact lens, using applanation (TonoPen XL(®)) and rebound (TonoVet(®)) tonometers in enucleated dog eyes. A total of 30 enucleated eyes from 15 beagle dogs. To measure accurate IOP, the anterior chamber of each enucleated eye was cannulated with two 26-gauge needles and two polyethylene tubes were connected vertically to an adjustable reservoir bag of normal saline and a pressure transducer. IOP was measured by the TonoPen XL(®) followed by the TonoVet(®) without a contact lens. After a contact lens was applied to the cornea, IOP was re-measured in the same order. Three consecutive IOP measurements were performed using both tonometers. Without the contact lens, the IOP values obtained by both tonometers correlated well according to the regression analysis (TonoVet(®): γ(2) = 0.98, TonoPen XL(®): γ(2) = 0.97, P contact lens was applied to the cornea. Bland-Altman analysis was used to determine the lower and upper limits of agreement (TonoVet(®): -29.7 and +21.1 mmHg, TonoPen XL(®): -3.9 and +3.6 mmHg) between the two devices. This study suggests that the TonoPen XL(®) is a useful tonometer for dogs wearing therapeutic contact lenses, and importantly, contact lenses would not need to be removed prior to IOP measurement. © 2012 American College of Veterinary Ophthalmologists.

    Assuming that photovoltaic power systems were installed at two points, Shinjuku Tokyo and Chino Nagano, a study was conducted of difference in generated output of the systems caused by the difference in environmental factors. In the study, it was assumed that two of the photovoltaic power system with rated capacity of 3kW were installed at the two points, and the annual generated output was calculated and compared by the conventional method considering only cell temperature and the output estimation method considering intensity of solar radiation, cell temperature, and spectral distribution of solar radiation. The result of the study was as follows: the difference in output ratio at the two points was 1.7% or lower under the influence of intensity of solar radiation and cell temperature. On the other hand, under the influence of the distribution of spectral solar radiation, the difference is larger than under other environmental factors, 2.4% in polycrystalline Si and 5.5% in amorphous Si. The generated output estimated by the conventional method and the spectral method produced a difference between 81 kWh in Tokyo and 258 kWh in Nagano in amorphous Si. This is because environmental factors such as intensity of solar radiation and distribution of spectral solar radiation are different between the two points. 1 ref., 2 figs., 3 tabs.

    Under the assumption of a large-capacity DC power transmission model project in the Far East and Siberia districts, technical study was made on the basic design of the project, considering selection of concrete power generation and consumption sites and power transmission routes, power transmission/transformation equipment, cables, and environmental impact. Study was also made on its applicability to similar projects in Japan. The model project aims at integration of Eastern Integrated Power System in the Far East and Russian Unified Power System, and development of abundant undeveloped hydraulic and tidal power generation in the Far East. The study result showed that (1) construction of the high-voltage DC power transmission (HVDC) system of model project class voltage and capacity in Eastern Siberia is possible technically enough, (2) the total construction cost of the model project scheduled to be put into operation in 2025 amounts to nearly $4.7 billion, and (3) the model project is environment-friendly without any CO{sub 2} gas emission because of hydraulic and tidal power generation.

    For investigating biological effects of a localized SAR (specific absorption rate) deposited in a human body for electromagnetic wave exposure, it is indispensable to graps a temperature-rise inside a human brain including the control center for the body temperature. This paper numerically analyzes a temperature-rise inside an eyeball of our developed realistic head model for 1.5 GHz microwave exposure, using the FD-TD (finite-difference time-domain) method. The computed results are validated in comparison with the data obtained by Taflove and his colleague. In order to examine a quantitative relationship between the localized SAR and temperature-rise, we also obtained a tissue amount over which the localized SAR should be averaged so as to well reflect the temperature-rise distribution inside the eyeball. 15 refs., 9 figs., 3 tabs.

    The objective was to compare distribution and intensity of muscular tonus in spastic tetra paretic cerebral palsy (CP), correlating the clinical data with lesion location in the central nervous system. Twelve children aged two to four years old with predominantly cortical lesions (six children) and subcortical lesions (six children) were included. The tonus was analyzed in the upper (UULL) and lower limbs (LLLL) based on Durigon and Piemonte protocol. The result showed that there was no significant difference regarding tonus intensity and distribution in the UULL and LLLL in both groups. Comparing the upper and lower limbs of subjects in the same group, the LLLL presented more asymmetry and higher tonus intensity than the UULL. It was concluded that in this study children with CP as a result of predominantly cortical or subcortical lesions present a similar deficit in tonus modulation, causing a symmetric and homogeneous distribution of hypertonicity, which is predominant in the LLLL.

METHODS: We conducted a pilot clinical study in 78 eyes of 78 subjects aged 22-28 years old (44 women and 34 men; mean age 23.8±1.19y. IOP was measured using GAT, I-Care and Tono-Pen tonometers, followed by measurements of CCT. Statistical analysis was performed using SPSS 20.0. RESULTS: The mean IOPs and standard deviation (±SD for GAT, I-Care and Tono-Pen were 15.62±2.281 mm Hg, 16.29±2.726 mm Hg and 16.32±2.393 mm Hg, respectively. The mean CCT was 555.15±29.648 μm. Clear positive correlations between GAT and I-Care, GAT and Tono-Pen, and I-Care and Tono-Pen tonometers were found (r=0.867, P0.05. Both non-gold standard tonometers were affected by CCT; that is, both I-Care and Tono-Pen tonometer values were significantly higher with higher CCT means (>555 μm; MD=−1.282, P555 μm were associated with overestimated IOP values.

    To identify the correlation between the difference of intraocular pressure measurements (IOP) obtained using the Goldmann applanation tonometer (GAT) and three others tonometers (Handheld applanation tonometer - HAT, Dynamic contour tonometer - DCT and Tono-Pen®) with biometric characteristics (corneal diameter, pachymetry, keratometry and axial length) in patients with congenital glaucoma. A cross-sectional study was performed on 46 eyes from 46 patients with congenital glaucoma. IOP measurements were obtained in all patients using GAT, HAT, DCT and Tono-Pen®. Keratometry, pachymetry, biometry and corneal diameter measurements were performed after the IOP measurement. The order of the tonometries was randomized. The correlations between the differences of IOP values of GAT and the other tonometers (Delta-IOP), and the different biometric parameters were studied. Tono-Pen® Delta IOP revealed moderate positive correlation to keratometry (r=0.41, p=0.004). The other Delta-IOPs showed no correlation with any of the biometric characteristics evaluated. IOP differences between GAT (gold standard) and GAT, HAT, DCT or Tono-Pen tonometers seem not to correlate with majority of ocular biometric characteristics. The only exception was the keratometry, which correlated in a positive and moderate way with Tono-Pen® Delta-IOP. This result suggests that the differences of IOP values of Tono-Pen® and GAT increase with the steepness of the cornea.

    In order to type the sausage-shaped bacteria forming A-type sulfur-turf, cell length distributions and physics-chemical conditions of hot spring waters were investigated on twelve samples collected from all over Japan. The frequency distributions of the cell length of eight samples were bimodal, while the other four samples were unimodal. In seven samples with bimodal distributions, two types (large and small) of the sausage-shaped bacteria could be differentiated. The cell length of the large-type was between 10.1 and 31.9{mu}m, while that of the small-type ranged 2.2 to 6.6{mu}m. The pH of seven hot spring waters were between 6 and 8, and the two types (large and small) formed together sulfur-turf. In contrast, pH of the three hot springs were over 8, and the two types of the sausage-shaped bacteria could not be detected in the sulfur-turf. Therefore, it is reasonable to set a third type of the sausage-shaped bacteria which prefers high-pH (over 8) and low calcium condition. The cell lengths of the third type were in the range of 5.5 to 8.6{mu}m, which correspond to the sausage-shaped bacteria of medium size. 20 refs., 5 figs., 2 tabs.

    A survey was carried out to identify the evaluation by British Industry on COP3 and the nation's future activities. In Britain, the gas emission level in 2000 is estimated to achieve sufficiently the initial target as the level is lower by 4 to 8% than that in 1990. This is largely attributable to substitution of coal by natural gas. At the Kyoto Conference, the European Union agreed with its target to reduce the emission of greenhouse effect gas over the period 2008-2012 to 8% below its 1990 level. Britain agreed to share its reduction rate at 12.5%. The Labour Party had set an election pledge since before the general election to reduce carbon oxide emission by 20% (against the 1990 level) by 2010, and the Prime Minister Tony Blair has also confirmed his commitment to this target. The policy making work to achieve the COP3 target has begun in 1998 when the UK Climate Change Program (consultation paper) was issued, and will continue until February 1999. The Advisory Committee of Business and Environment representing British Industry has already published their advice on how to achieve Britain's COP3 objective, which are considered by the government in the above mentioned paper.

Possibility of use of air flow heat energy using the mine ventilation in order to economize and save energy of this cultivation was studied. If continuous green house ventilation is carried using air drawn from tunnel, applicable house temperature and humidity for certain scale of green house was possible to control within constant limit. When warming of 4 green houses from November to April was carried out, the maximum power load, the heating load for January, was 1,746.43kW and ventilation rate was 5.51 times/hour. Consumption for February was higher than January because of decrease of airflow drawn energy inside the tunnel. As for cooling from July to September, for August as the hottest month, maximum consumed energy required to maintain green house temperature was 2,058.28kW, and demand of airflow rate drawn inside the tunnel was 128.38m[sup 3]/s. 7 refs., 7 figs., 5 tabs.

    It is intended to participate in the IEA international cooperation project related to DSA, exchange items of information, and promote demonstration and survey of new load leveling methods. The existing and newly proposed DSM mechanisms as the achievement of the previous tasks were put into order. The arena of information exchange and discussions was prepared through use of the Internet homepage for the IEA/DSM implementation agreement. Necessary official policies were also made available. Points of precautions when the mechanisms of other countries are used in Japan: the key to the success depends on social or cultural situations that work as the base; therefore, comparisons and analyses are necessary on such elements as customers as the object, energy projects and governments; compatibility of the situation and pattern of the demand side with the DSM technologies governs the reasonability thereof; the types of the mechanisms are narrowed down by size of the customer division, consumption pattern, electric power quality and safety, and needs on the flexibility; proliferation levels of the DSM technologies determine the appropriate mechanisms; and how the DSM is conceived against the final consumption is governed by the conception by both of the customers and the government.

    Reactions of various model compounds were investigated using synthetic pyrites for coal liquefaction. In this study, successive changes of the catalysts were investigated from the reactions of model compounds by using three different synthetic pyrites with the lapse of time after production. Benzyl phenyl ether, dibenzyl, and n-octylbenzene were used as model compounds. Reactions were conducted in an autoclave, into which sample, catalyst, decalin as solvent, and initial hydrogen pressure 10 MPa were charged. The autoclave was held at 450 or 475{degree}C of reaction temperature for 1 hour. The catalyst with a shorter lapse of time after production acted to hydrogen transfer, and inhibited the formation of condensation products due to the stabilization of decomposed fragment. It also acted to isomerization of materials by cutting alkyl side chains. When adding sulfur to the catalyst with longer lapse of time after production under these reaction conditions, it inhibited the formation of condensation products for the reaction of benzyl phenyl ether. However, it did not provide the effect for the reaction of n-octylbenzene. 5 refs., 3 figs.

    A method for curing CFRP composite structures by using Joule effect is presented. Due to the presence of fiber to fiber contact, CFRP composites and their prepregs exhibit electrical conductivity in the direction transverse to fibers as well as in the fiber direction, and they can be considered as electrically homogeneous on a gross scale. Therefore, passing an electric current through a CFRP prepreg, it is self-heated due to the Joule effect. Feedback current control maintains the prepreg temperature at a desired level and makes the prepreg be cured by a specified cure cycle. Experimental verifiactions have been carried out to demonstrate the feasibility of the present technique. The applications to the bonding of CFRP components and to the patch repairs of effective CFRP structure are also described. 12 refs., 12 figs.

    The effort aims to develop a sensor system to enable overall VDC (vehicle dynamic control). The goal is to manufacture a small module type sensor system more than 20 times higher than the conventional type in responding speed and accuracy, which will use a novel ABS (anti-lock braking system) capable of direct and real-time measurement of axial forces in the four directions. The prototype module will be a package in which a system-on-a-chip accommodating peripheral circuits is integrated with a sensor. In the effort to develop a novel multi-axial sensing system (MASS) for a smaller ABS, a circuit optimization technology was developed. A dedicated IC (integrated circuit) was developed for a system to process a large volume of signals. In the effort to develop technologies for packaging the novel sensor system and for constructing modules, technologies were developed for integrating sensor components and an IC into one, module junctioning, module installation, simplification of the installation process, and for the manufacturing of modules. Developed in the effort to optimize MASS were technologies involving the selection and evaluation of sensor components and the enhancement of such processes, optimization of the sensor itself, and the improvement of the sensor system for higher efficiency in calculation. Sensor modules were tested aboard vehicles and the compatibility of the system-on-a-chip with the MASS module was confirmed. (NEDO)

    A survey was carried out on activities taken in Germany. The industry has a strong opinion to take voluntary regulations rather than those by laws. The nation's activities are being moved forward centrally with the suppression policies that follow the declaration on the voluntary regulation by the German industry to prevent global warming, which had been submitted by the German Industry Federation to the federal government in 1996. The participation to the declaration, which is optional, covers 71% of the energy consumption by manufacturing industries and 99% of the public electric power consumption, but large-scale industrial departments such as machine and electric power sectors who have not participated can also been found. The plan calls for reduction of inherent CO2 and energy per added value production amount in the entire industry by as much as 20% of the result in 1990 by 2005. According to the third party monitoring system employed by the federal government, the industry submits results of periodical analyses to the government. According to the result, the industries participated in the voluntary regulation have achieved annual exhaust suppression of 42 million tons during the period of 1990 to 1996. The public electric power industrial department whose CO2 emission accounts for a little less than 30% of the nation's total emission amount has a great effect. The industry is making efforts to improve the power generation efficiency aiming at reduction of CO2 emission of 12% of the 1990 result by 2015. (NEDO)

    Participation was implemented to the IEA/DSM task VI as the demonstrative investigation of a new load leveling method. The DSM strategy is a means to achieve the public objectives of wide range, wherein the DSM mechanism is important, that can obtain accurate and useful information in competitive markets. Consumer protecting activities have close relation with general information needs. A financial incentive mechanism is also necessary to support nurturing of business organizations and new ESCO industries. A market forming mechanism using the DSM can solve the problem of disagreement in the incentives (for example, private profit of electric power companies and the public nature of the government). These include system plans considering the DSM, setting of upper limit in the profit, demand side bidding, and green charge institution. It is important to utilize affluent findings and means used in the past and utilize each mechanism to meet the needs for public benefit at the present and in the future, while structuring an electric power business structure incorporating the DSM. The DSM promoting mechanisms in each country were classified and put into order of regulations, supports, funds, and markets. (NEDO)

    A heat pump system utilizing the domestic waste water was introduced into a gymnasium owned by Hokkaido Electric Power to elucidate the applicability of domestic waste water as a thermal source of heat pump in the cold region. The gymnasium is a two-storied concrete building with the floor space of 2292m{sup 2}. Ground water at temperatures from 10 to 20{degree}C is utilized for the water supply. Made to flow together as waste water, the dirty water and daily exhaust water are discharged at the rate of 100t/day into a river after passing through the septic tank. Higher by 5 to 15{degree}C than the atmospheric temperature, the discharging temperature is kept higher than 10{degree}C even during the very cold period. The domestic waste water is almost neutral in pH, and normal in both SS and BOD. The heat pump was utilized for two stages, i.e., thermal collection and temperature heightening. The capacity of a sewage storage tank tank was made to be 170m{sup 3} to meet the thermal load of 139000kcal/h in the gymnasium. The temperature of 15{degree}C could be kept during the air heating trial. The system is about 2 in coefficient of performance. The K-value of heat exchanger decreased by about 30% after seven months of operation. Upon its overhauling, its K-value recovered to 2.37, so that it must be overhauled once a year. 5 refs., 15 figs. 4 tabs.

    Riding comfort in a cabin of a high-speed hydrofoil catamaran was evaluated by comparing with that in ordinary boats as to acceleration in the vertical direction as one of the responses of the catamaran in waves. First, an equation of motion in waves was introduced, and considerations were given while comparing the result of calculations in regular waves with that of model experiments. Comparison and verification were also performed on response characteristics in irregular waves. A new-type boat, whose cabin is supported with four springs, and provided with hydrofoils in front and rear thereof, was verified to have much less motions of the catamaran bodies and the cabin than in the ordinary boats both in regular and irregular waves. This result was proven by numerical calculations and model experiments. Hydrofoils affect largely the reduction in motions. The correlational data between the results of calculations and experiments are considered sufficient to provide design data, although there are still some points to be improved. These results revealed that the riding comfort of the new-type boat has been improved over that in the ordinary boats. 6 refs., 11 figs., 3 tabs.

    Current electricity markets in Europe and the USA are drastically changing due to the introduction of competition principle and the reconsideration of business systems. Are also changing the activities and their forms of DSM (demand side management) for load leveling which has been conventionally conducted by electricity companies for the efficient operation of facilities. Task IV and Task VI aim at developing new mechanisms to promote DSM in the changing electricity markets as well as disseminating and communicating information on the new mechanism. Japan participates in Sub-task IV/6 and 7 and Task VI. Activities for developing new mechanisms are divided into Phase 1 and Phase 2. The Phase 1 includes review of existing mechanisms and preliminary development and evaluation of new mechanisms. The Phase 2 includes the detailed development of new mechanisms and evaluation criteria, communication and information about mechanisms, and identification of the public policy implications which would follow a decision by the responsible authorities to implement each of various DSM mechanisms. The time frame of Phase 1 is between February 1996 and March 1997, and that of Phase 2 is between January 1997 and December 1999. 2 figs., 4 tabs.

    Since the CO{sub 2} emission reduction cost is high under the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) rulings, they have made it clear that they will positively resort to the flexibility mechanism. This is to reserve a room for freely selecting power generation methods other than nuclear technologies with their nuclear power plants scheduled for renovation in the neighborhood of 2010. But the industrial circles are slow in responding, failing to accept the carbon fund concept. As for measures for greenhouse gas emissions reduction, since they depend on energy saving for their success, the response specially of the transportation division will be the key. In the industrial division, success depends on a voluntary consensus among industries that consume much energy. As steps to economize the trend of people's energy consumption, an energy tax and environmental tax are scheduled to be imposed. An overall program for greenhouse gas emission reduction is being drafted by a government committee, with the outline to be made known in May 1999 for finalization in autumn the same year. A power market liberalization bill has already been prepared, and a decision will soon be made on a plan for the second phase targets.

    The paper developed an analysis method of the energy supply/demand structure of city and compared the conventional city and a city considering energy conservation. An energy supply/demand flow chart was newly proposed. From this flow chart, `energy sustainability ratios` was proposed as a new index for comprehensively evaluating two elements of the energy conservation by load reduction and heightening of energy conversion rates and the utilization of waste heat and renewable energy. A method for analysis of the energy supply/demand structure of city was developed including daily supply/demand patterns in the area where individual equipment in every residence/building correspond to the energy supply and the area where centralized energy systems such as district energy supply correspond it. From the developed analysis method, analysis was made of a newly developed city with a 0.6 million population in terms of the conventional city and energy conservation city, to clarify the present energy supply/demand structure of city and to express it in an energy flow chart. At the same time, validity of the analysis method and evaluation indexes were confirmed by comparing the conventional city and energy conservation city. 15 refs, 27 figs., 17 tabs.

    There has been tried to apply unified assessment method using hot spot stress, which is effective to evaluate fatigue strength of fillet welded structures for ships and marine structures. This method can be applied to complicated structures and is independent of welding processes. In this study, first, stress analysis has been conducted for two-dimensional fillet welded joint models with various combinations of plate thickness and weld leg length of general fillet structures by means of boundary element method. Then, critical position, which is not affected by local stress concentration due to bead, was determined from the detailed stress distribution in the vicinity of weld toe. As a result, a general equation has been proposed to estimate the hot spot stress by one-point representative method. Second, the fatigue tests of typical fillet welded joints have been conducted by applying this method. Consequently, it was demonstrated that the unified fatigue strength can be evaluated by the S-N data based on hot spot stress range determined from the proposed equation, independent of structural stress concentration. 22 refs., 14 figs.

    For use in energy self-sufficient buildings, a system was studied capable of retaining for its own use the excess of power produced by a photovoltaic power generation system without releasing it to the commercial system. Summertime cooling was considered. The storage battery cooling system was provided with two solar cell systems and, in the daytime, one was used for cooling and the other for charging batteries for nighttime cooling. In the cold heat storage cooling system, cold heat accumulators (red bricks) were provided in the wall and floor, and under the floor, and the floor was a grating for proper ventilation between the room and underfloor space. With the solar cell-driven air conditioner out of operation, cold heat was fed to the room from the underfloor cold heat accumulators by a fan. In storage battery cooling, solar power covered 60% of what the air conditioner used. In the presence of sufficient power in storage, the air conditioner stayed on at night without buying commercial power, when the room temperature was 25{degree}C. In the cold heat accumulation cooling, 50% of the air conditioner power consumption was covered by solar power. It is recommended to install cold heat accumulators not in the room but in a separate space, such as the underfloor space, where they are exposed to the cooling cold air direct from an air conditioner for future retrieval of cold heat. 2 refs., 9 figs., 3 tabs.

    The outline of a model for architectural systematization of natural energy conversion and the experiment result on the basic thermal performance in winter are described. The model is about 20 m{sup 2} in floor space. Foam polystyrene of 100 mm and 200 mm thick was used for the outer wall as heat insulating materials. The model has a solar battery and air conditioner and uses red brick as a heat reservoir. An experiment was made on seven modes obtained when three elements (heating, heat storage, and night insulated door) are combined. The information obtained by the experiment showed that a model for architectural systematization has high heat insulation and tightness and can be used as an energy element or an evaluation model for architectural systematization. In this model for architectural systematization, the power consumption of an air conditioner in winter can be fully supplied by only the power generation based on a solar battery. In an architectural element, the heating energy consumption can be remarkably reduced and the indoor thermal environment can be greatly improved, by the combination of a heat reservoir and night heat insulated door. 1 ref., 6 figs., 3 tabs.

    This paper describes the following matters related to amendment of oil related systems which will be enforced according to the result of discussions at the Petroleum Council on the ways the oil product supply should be in the future. The temporary measure law for importing specific oil products shall be abolished when it will be expired in March 1996. This is because the law has limited the oil product importing organizations only to oil companies who have oil refining capabilities, and the continuation of the law would lose its justifiability under the present circumstances in the petroleum industry. The oil reservation law is then amended so that the emergency handling ability on oil supply will not be hampered even after possible expansion in the number of oil product importing organizations as a result of the abolishment of the temporary measure law. The quality management systems for oil products will also be revised so that the present level on quality items of the minimum necessity will not be declined with respect to the environments and safety. Furthermore, the area designating system that has been limiting erection of oil service stations will be repealed by October 1996. 2 tabs.

    The winnowing fan used for head feeding type combines draw in air along the axis from the inlet of both sides, and then radially discharges it into scroll. Therefore, the internal flow of this fan shows a strong three-dimensionality and the efficiency is low. In order to improve the efficiency and make the axial distribution of discharge flow uniform, the experimental and numerical investigations were carried out. Numerical results using CFD agree well with experimental ones for the mean flow. It is found that this numerical simulation method is useful for investigation of the effect of blade and casing configurations. Moreover unsteady flow conditions in the impeller though rotations are shown. For example, in the impeller, a vortex formed around the leading edge of the blade, grows connect with another one, reduce and disappear. (author)

    Among the items of the solvent extraction and liquefaction plant technologies in the Sunshine Project in fiscal 1981, this paper describes the achievements in developing a 1-t/d experimental plant and the solvent extraction and liquefaction process. Basic facilities were completed by giving expansion constructions on the extraction reaction column, gas-liquid separation column, and hydrogenation reaction column. The operation was performed with the primary object placed on verifying the effect of measures on problems that have been extracted, and checking the solvent balance. The conversion rate at an extraction reaction temperature of 450 degrees C was 83%, agreeing with the result of the fundamental study. The solvent has turned light as a result of 153-hour continuous operation, but circulating use was possible. Progress of the reaction has become easily controllable in the hydrogenation system. Fundamental discussions were given on engineering aspects, which require further accumulation of data. In the research of the solvent extraction and liquefaction process, fiscal 1981 has performed discussions on liquefaction catalysts, and on the effect of the hydrogen donating solvents. The discussions were for the fundamental research to establish adequate conditions for the 1-t/d experimental plant by operating a small continuous operation facility to its full extent, and by using a batch type reaction device. Screening was also carried out on catalysts. (NEDO)

    This paper describes the achievements in the Sunshine Project in fiscal 1981 in development of a solvolysis liquefaction plant. The solvolysis process is characterized by performing the first stage reaction (liquefaction) in a short time by using hydrogenated heavy solvent produced spontaneously in the process. This short-time liquefaction reaction was carried out continuously by using a 1-t/d experimental plant, and a prospect was obtained on smooth operation and realization of the device. A test using a testing device allowing the temperature to rise within several minutes was performed on the effectiveness of a hydrogenated coal based heavy solvent (fractions of a hydrogenated heavy anthracene as a model) as a study on the first stage reaction. Partially hydrogenated materials of polycyclic condensed aromatics in the heavy solvent is largely involved in the initial reaction. In the solid-liquid separation, solids and heavy fractions are selected and removed from the first stage reaction products, and the light fraction is supplied into the second stage reaction (hydrogenation). The solvent deliming process was tested by using a batch type solid-liquid separator, whose effectiveness was verified. Studies were performed by using Australian sub-bituminous coal on operation of a continuous operation device consisted of systems for the first stage reaction (liquefaction), solid-liquid separation, second stage reaction (hydrogenation), and solvent circulation.

    Study was made on the design of experiments for confirming the technological and economical feasibility of commercial production of Mn nodules. An experimental sea area was selected considering Mn nodule characteristics such as concentration, continuity of nodule distribution and nodule size, and sea bottom topographic features such as flatness and exposed bed rock disturbing traveling of nodule collectors. The experimental plan was decided on the basis of the survey and study on an experimental scale, various requirements, weather and sea weather features of the sea area, and sea bottom conditions. Based on the experimental plan, various verification tests and simulation analyses were carried out, and functions of various equipment were confirmed. The conceptual design of a mining system assumed both pump-lift and air-lift systems, and yearly production rates of 2 and 3 million tons by 2 mining barges, and summarized main points of every system. As the evaluation result, the future direction of commercial production of Mn nodules was clarified to a certain extent. 5 figs., 21 tabs.

    The purpose of this prospective study was to describe intraocular pressure (IOP) and examination findings in three tree frog species (Cruziohyla craspedopus [fringe leaf frog], Cruziohyla calcarifer [splendid leaf frog], and Anotheca spinosa [spiny-headed or coronated tree frog]). Thirty-one C. craspedopus, four C. calcarifer, and five A. spinosa were weighed, sexed based on phenotype where possible, and examined using slit-lamp biomicroscopy and indirect ophthalmoscopy. IOP was measured using the TonoVet and TonoLab rebound tonometers while the frogs were held two ways (unrestrained, then restrained). Statistical differences were determined using one-way analysis of variance (ANOVA) and t-tests. Mean ± SD IOP (TonoVet and TonoLab, respectively) was 15.1 ± 2.5 mmHg and 15.6 ± 4.1 mmHg in C. craspedopus; 14.8 ± 1.5 mmHg and 18.8 ± 3.1 mmHg in C. calcarifer; and 9.1 ± 2.1 mmHg and 10.8 ± 1.4 mmHg in A. spinosa. There was no significant difference in IOP in C. craspedopus by eye (Right vs Left), tonometer, or restraint method. IOP in female C. craspedopus was 1-3 mm Hg higher than in males with both devices (P Cruziohyla genus frogs and A. spinosa for the TonoVet (P < 0.05). There was no difference in IOP measurements between the TonoVet and TonoLab in C. craspedopus. IOP varied by gender in C. craspedopus and between species, but not by tonometer. Ocular abnormalities were minimal in this group of captive bred frogs.

    To analyze the correlation of Goldmann applanation tonometer (GAT), I-Care tonometer and Tono-Pen tonometer results in young healthy persons, and to investigate the influence of central corneal thickness (CCT) on intraocular pressure (IOP) measurements recorded with these tonometers. We conducted a pilot clinical study in 78 eyes of 78 subjects aged 22-28 years old (44 women and 34 men; mean age 23.8±1.19y). IOP was measured using GAT, I-Care and Tono-Pen tonometers, followed by measurements of CCT. Statistical analysis was performed using SPSS 20.0. The mean IOPs and standard deviation (±SD) for GAT, I-Care and Tono-Pen were 15.62±2.281 mm Hg, 16.29±2.726 mm Hg and 16.32±2.393 mm Hg, respectively. The mean CCT was 555.15±29.648 µm. Clear positive correlations between GAT and I-Care, GAT and Tono-Pen, and I-Care and Tono-Pen tonometers were found (r=0.867, P0.05). Both non-gold standard tonometers were affected by CCT; that is, both I-Care and Tono-Pen tonometer values were significantly higher with higher CCT means (>555 µm; MD=-1.282, Ptonometers overestimated IOP compared with the GAT values. Either the I-Care or Tono-Pen tonometer could be used instead of GAT because there was no significant difference between their results. Higher CCT values (>555 µm) were associated with overestimated IOP values.

    To determine the accuracy and reproducibility of intraocular pressure (IOP) measurements obtained with the TonoVet® rebound tonometer in cynomolgus macaques and to determine the effects of corneal thickness on measurements obtained by the TonoVet®. The anterior chambers of both eyes of anesthetized monkeys were cannulated with branched 23-G needles; one branch was connected to a vertically adjustable reservoir and the other to a pressure transducer. IOP was increased by 5 mmHg increments and then decreased by 10 mmHg decrements. IOP was measured using the TonoVet® at each increment and decrement by 2 independent observers and at every other increment and every decrement by a single observer using 'minified' Goldmann applanation tonometry. Central corneal thickness was measured with a PachPen(TM) ultrasonic pachymeter. TonoVet® readings correlated well with manometric IOP (slope = 0.972, r(2) coefficient = 0.955). No significant differences were observed when comparing eyes or operators; however there was a non-significant trend for TonoVet® readings taken in right eyes to be closer to manometric IOP than those taken in left eyes. The TonoVet® had a non-significant tendency to underestimate manometric IOP. TonoVet® readings obtained during the decremental phase of the experiment were significantly closer (p tonometer is a reliable and accurate tool for the measurement of IOP in cynomolgus macaques. This tonometer has several advantages, including portability, ease of use, and brief contact with the corneal surface making topical anesthetics unnecessary. Copyright © 2011 Elsevier Ltd.

    Concerning the Manito Lowlands geothermal field and the Montelago geothermal field where the systems are to be newly installed, the geothermal reservoir characteristics are assessed, and cost effectiveness is compared between different power generating systems. According to the investigations conducted into the two geothermal fields in the past, they are supposed to have geothermal potentials of the medium grade. Chemical analyses are conducted anew on this occasion into the hot spring water and fumarole gas, and the MT (magnetotelluric) method is implemented for the survey of reservoir distribution. It is now expected that approximately 20MWe will be exploited from each of the two geothermal fields. The power generation systems studied are the single flash type and double flash type for the conventional power generation system, and the cascade type, bottoming type, and two-phase binary type for the combined binary power generation system. As the result, it is concluded that the double flash type or two-phase binary type will be advantageous to the Manito Lowlands geothermal field, and the double flash type or bottoming type or two-phase binary type will be advantageous to the Montelago geothermal field.

    Research and development was carried out involving fine ceramic sintered body textural structure evaluation methods for the development of process technologies for achieving higher quality and lower cost. Studies centered about a method for evaluating coarse pores and coarse grains in sintered bodies, relations between sintered body fracture strength and textural structure, and the standardization of evaluation methods. As the result, an evaluation method for observing pore structures in a sintered body flake specimen under an optical microscope and another for observing coarse grains under a polarization microscope were proposed. As for the effect of coarse defects on the fracture strength of ceramics, it was demonstrated experimentally and theoretically that coarse defects several tens of micrometers in size greatly affected the fracture strength. In the study of methods for sintered body grain size evaluation, findings were obtained about the processing of the specimen surface. (NEDO)

We believe that the public and especially the local residents should have a precise understanding of the MIU project. Therefore, to provide information we have used virtual reality (VR) technology in the project since 1996. Software to introduce both the MIU Project and the geology of the Tono district has been completed. The Tono district is characterized by uranium ore deposits, and by clay deposits which are used by the pottery industry. Software with some amusement value, such as hot spring drilling, has also been completed. We plan further software development of VR technology to increase the feeling of realism. (author)

    The ICare (Tiolat Oy, Helsinki, Finland) is a new portable tonometer that measures intraocular pressure (IOP) with a new rebound method, in which a very light probe is used to make momentary contact with the cornea in slow motion. The purpose of this study is to assess the accuracy of the ICare IOP measurements by comparing them against other portable tonometers: Perkins applanation tonometer and Tono-Pen XL digital tonometer (Medtronic Solan, Jacksonville, FL). Sixty-five young subjects were assessed with each of the tonometers. ICare tonometry was performed first, followed by Perkins applanation tonometry and Tono-Pen XL in a random order. Regression analysis was used to evaluate the relationship between the Perkins tonometer and the remaining tonometers used in this study. Tonometers were also compared by plotting the difference between the methods against the mean. The hypothesis of zero bias was examined by a paired t test and the 95% limits of agreement (LoA) were calculated. ICare and Tono-Pen XL significantly overestimate IOP when compared with Perkins applanation tonometry. The mean of the difference between Perkins and ICare and Perkins and Tono-Pen XL was (mean +/- standard deviation) -3.35 +/- 2.28 mm Hg and -2.78 +/- 2.53 mm Hg, respectively. The 95% LoA between Perkins tonometry and ICare tonometry were between -7.81 and +1.12 and between Perkins tonometry and Tono-Pen XL tonometry between -7.74 and +2.18. Compared with Perkins tonometry, the ICare tonometer allows clinicians to estimate IOP with a portable, rapid, and noninvasive method with similar reliability to that offered by Tono-Pen XL. Clinicians should be aware of the systematic overestimation of IOP with the ICare. Further research is needed to evaluate the performance of rebound tonometry in populations with higher IOP and assess the reliability of this technique in the early detection and follow up of glaucomatous patients.

IOP measurements were compared and the effects of head position and presence of contact lenses on the resultant values were analyzed. the average difference between the recumbent and sitting positions was 3.56, 2.68, and 2.62 mm Hg for the Tono-Pen tonometer, Phosphene tonometer, and TERT, respectively. There was an increase of 5.60, 2.78, and 2.63 mm Hg in hyperextension compared to sitting for the Tono-Pen tonometer, Phosphene tonometer, and TERT, respectively. The difference in the IOP values obtained in the presence and absence of therapeutic contact lens for the three instruments in the three positions was between -1.23 and +1.47 mm Hg. IOP measurements of bedridden patients are only slightly higher than those of sitting patients except for the Tono-Pen tonometer in the hyperextension position. The presence of contact lenses does not affect IOP values obtained by the three evaluated instruments.

    Intraocular pressure is affected by corneal thickness and biomechanics. Following ablative corneal refractive surgery, corneal structural changes occur. The purpose of the study is to determine the relationship between the mean central corneal thickness (CCT) and the change in intraocular pressure measurements following various corneal ablation techniques, using different measurement methods. Two hundred myopic eyes undergoing laser in situ keratomileusis (LASIK) or photorefractive keratectomy (PRK) were enrolled into a prospective, non-randomized study. Corneal parameters examined included full ocular examination, measurement of CCT, corneal topography, corneal curvature and ocular refractivity. Intraocular pressure measurements were obtained using three different instruments-non-contact tonometer, Goldmann applanation tonometer and TonoPen XL (TonoPen-Central and TonoPen-Peripheral). All measurements were performed pre-operatively and 4 months post-operatively. Post-operative intraocular pressure was significantly lower than pre-operative values, with all instruments (p value tonometer and non-contact tonometer (p value < 0.001, ANOVA). Intraocular pressure readings are significantly reduced following corneal ablation surgery. We determined in our myopic patient cohort that the TonoPen XL intraocular pressure measurement method is the least affected following PRK and LASIK as compared to other techniques.

    Although isolation racks are superior to open-type racks in terms of securing breeding conditions for laboratory animals, the contingency-proofing capability of the former has yet to be determined. Therefore, from the view of risk management, we studied the environmental change in isolation racks by forcibly suspending ventilation and air-conditioning and confirming the maximal time length for complete recovery to the original condition after restarting their operations. The isolation racks were placed in a room that was equipped with an independent air-conditioning system. When the inside condition of the racks reached 22-24 degrees C and 59-64% of relative humidity, the air-conditioning and ventilation were forcibly suspended and the subsequent temperature, relative humidity, ammonium and CO2 concentrations in the racks were measured over time. We found that after suspending the air-conditioning and ventilation, it took 40-60 min for temperature, and about 10 min for relative humidity to exceed the maximum values (temperature and relative humidity) referred to in the Showa 58 Nenban Guideline Jikken Doubutsu Shisetsu no Kenchiku oyobi Setsubi (Guidelines of buildings and facilities for experimental animals in Japan; Year 1983 edition). After 17 hr 25 min of the suspension of air-conditioning and ventilation, two rats were found dead. Then, the air-conditioning and ventilation were restarted. It took about 2 hr for temperature, and 50 min for relative humidity to regain the guideline values. The ammonium concentration stayed within the guideline value with a maximum concentration of 2 ppm in the experimental period, whereas the CO2 concentration was found to exceed 9% at the time of animal death.

Many tertiary and quaternary amines present in consumer products (e.g., pharmaceuticals, personal care and household products) are known to be N-nitrosodimethylamine (NDMA) precursors during chloramination, but the formation of other N-nitrosamines has been rarely studied. This study investigates the specific and total N-nitrosamine (TONO) formation potential (FP) of various precursors from nitrogen-containing micropollutants (chlorhexidine, metformin, benzalkonium chloride and cetyltrimethylammonium chloride) and tertiary and quaternary model amines (trimethyl amine, N,N-dimethylbutyl amine, N,N-dimethylbenzyl amine and tetramethyl ammonium). All the studied nitrogenous micropollutants displayed quantifiable TONO FP, with molar yields in the range 0.04-11.92%. However, the observed TONO pools constituted mostly of uncharacterized species, not included in US-EPA 8270 N-nitrosamines standard mix. Only the quaternary ammonium compound benzalkonium chloride showed quantifiable NDMA FP (0.56% molar yield), however, explaining only a minor fraction of the observed TONO FP. The studied model amines showed molar NDMA yields from 0.10% (trimethyl amine) to 5.05% (N,N-dimethylbenzyl amine), very similar to the molar TONO yields. The comparison of the FPs of micropollutants and model compounds showed that the presence of electron donating functional groups (such as a benzyl group) in tertiary and quaternary amine precursors leads to a higher formation of NDMA and uncharacterized N-nitrosamines, respectively. LC-qTOF screening of a list of proposed N-nitrosamine structures has enabled to identify a novel N-nitrosamine (N-nitroso-N-methyldodecylamine) from the chloramination of benzalkonium chloride. This finding supports the hypothesis that different functional groups in quaternary amines can act as leaving groups during chloramination and

    We have continued our laboratory studies of forward gasification in small blocks of coal mounted in 55-gal drums. A steam/oxygen mixture is fed into a small hole drilled longitudinally through the center of the block, the coal is ignited near the inlet and burns toward the outlet, and the product gases come off at the outlet. Various diagnostic measurements are made during the course of the burn, and afterward the coal block is split open so that the cavity can be examined. Development work continues on our mathematical model for the small coal block experiments. Preparations for the large block experiments at a coal outcrop in the Tono Basin of Washington State have required steadily increasing effort with the approach of the scheduled starting time for the experiments (Fall 1981). Also in preparation is the deep gasification experiment, Tono 1, planned for another site in the Tono Basin after the large block experiments have been completed. Wrap-up work continues on our previous gasification experiments in Wyoming. Results of the postburn core-drilling program Hoe Creek 3 are presented here. Since 1976 the Soviets have been granted four US patents on various aspects of the underground coal gasification process. These patents are described here, and techniques of special interest are noted. Finally, we include ten abstracts of pertinent LLNL reports and papers completed during the quarter.

    To compare the reliability and accuracy of intraocular pressure (IOP) measured while wearing soft contact lenses (SCLs) using a non-contact tonometer (NCT), Goldmann applanation tonometer (GAT), iCare rebound tonometer (RBT) and the Tono-Pen XL. Twenty-six healthy subjects were examined. The IOP was measured using NCT, GAT, RBT, and the Tono-Pen XL, while the subjects wore SCLs -5.00 D, -0.50 D and +5.00 D. Bland-Altman plots and a regression analysis were used to compare the IOPs obtained with those instruments and the IOPs of the naked eyes measured using GAT (the standard IOPs in this study). The IOPs obtained by the Tono-Pen XL while the subjects were wearing -5.00 D, -0.50 D, and +5.00 D SCLs were significantly higher than those of the naked eyes obtained using GAT. RBT showed that the IOPs were similar to the GAT standard IOPs under all conditions. The IOPs measured with NCT and GAT while the subjects were wearing -5.00 D and -0.50 D SCLs were similar to the GAT standard IOPs. The IOPs obtained with RBT and NCT while the subjects were wearing -5.00 D and -0.50 D SCLs exhibited a good correlation with the standard IOPs. The NCT and RBT are best when measuring IOP through hydrogel SCLs.

    Purpose To evaluate the usefulness of the TonoVet™ rebound tonometer in measuring intraocular pressure (IOP) of monkeys. Methods The accuracy of the TonoVet™ rebound tonometer was determined in cannulated eyes of anesthetized rhesus monkeys where IOP was controlled by adjusting the height of a connected perfusate reservoir. To assess the applicability of the equipment through in vivo studies, the diurnal fluctuation of IOP and effects of IOP-lowering compounds were evaluated in monkeys. Results IOP readings generated by the TonoVet™ tonometer correlated very well with the actual pressure in the cannulated monkey eye. The linear correlation had a slope of 0.922±0.014 (mean±SEM, n=4), a y-intercept of 3.04±0.61, and a correlation coefficient of r2=0.97. Using this method, diurnal IOP fluctuation of the rhesus monkey was demonstrated. The tonometer was also able to detect IOP changes induced by pharmacologically active compounds. A single topical ocular instillation (15 μg) of the rho kinase inhibitor, H1152, produced a 5–6 mmHg reduction (pmonkey eye. PMID:19898690

    In the fiscal year of 2003, our committee achieved the following work items during the contract period, from September 3rd, 2003 to February 13th, 2004. The more accurate numerical data with respect to the geological/geometrical conditions including the fault were provided from Tono Geoscience Center and the numerical models by Finite Element Method (FEM), Finite Difference Method (FDM) and Boundary Element Method (BEM) were built taking those strata data into account. For small region modeling by FEM, three layers models, Shoumasama model and Tono-Shoumasama model, as well as Tono Mine model, were constructed, and each strain state at the far field boundary was determined. In order to get better agreement in local stress states with the measured values, a far field strain state was determined to the modified model in which material properties of upper granite and lower granite are different. In intermediate region modeling by FDM, actual strata data was taken into account, whereas strata boundary was assumed to be horizontal in former modeling, and far field stress field was analyzed. Intermediate region modeling by BEM was also carried out and far field stress state was determined. In wide region modeling by FEM, the fault was build in the model and fault slip was taken into account, and evaluation of strain state at the far field boundary was carried out for inhomogeneous rock including fault. It was proposed to output three-dimensional distribution of the maximum shear stress coefficients in order to advance three-dimensional modeling. It will make clear effect of shape, scale and property of the fault on stress state characteristic. This report describes minutely the results of the studies mentioned above. (author)

    Recent research and investigation show that the Tono uranium deposit and its natural uranium-series nuclides have been preserved, without any significant changes like re-migration or reconcentration, throughout geological events such as upheaval-submergence, marine transgression-regression, and faulting which can readily change geological, hydrogeological, and geochemical conditions. This situation might have come about as a result of being kept in a geometrical closure system, with reducing and milk alkalic geochemical conditions, from the hydrogeological and geochemical point of view.

  1. Impact of Nitrification on the Formation of N-Nitrosamines and Halogenated Disinfection Byproducts within Distribution System Storage Facilities.

    Zeng, Teng; Mitch, William A

    2016-03-15

    Distribution system storage facilities are a critical, yet often overlooked, component of the urban water infrastructure. This study showed elevated concentrations of N-nitrosodimethylamine (NDMA), total N-nitrosamines (TONO), regulated trihalomethanes (THMs) and haloacetic acids (HAAs), 1,1-dichloropropanone (1,1-DCP), trichloroacetaldehyde (TCAL), haloacetonitriles (HANs), and haloacetamides (HAMs) in waters with ongoing nitrification as compared to non-nitrifying waters in storage facilities within five different chloraminated drinking water distribution systems. The concentrations of NDMA, TONO, HANs, and HAMs in the nitrifying waters further increased upon application of simulated distribution system chloramination. The addition of a nitrifying biofilm sample collected from a nitrifying facility to its non-nitrifying influent water led to increases in N-nitrosamine and halogenated DBP formation, suggesting the release of precursors from nitrifying biofilms. Periodic treatment of two nitrifying facilities with breakpoint chlorination (BPC) temporarily suppressed nitrification and reduced precursor levels for N-nitrosamines, HANs, and HAMs, as reflected by lower concentrations of these DBPs measured after re-establishment of a chloramine residual within the facilities than prior to the BPC treatment. However, BPC promoted the formation of halogenated DBPs while a free chlorine residual was maintained. Strategies that minimize application of free chlorine while preventing nitrification are needed to control DBP precursor release in storage facilities.

    Investigation for characterization of rock properties of the Excavation Disturbed Zone (EDZ) were carried out in NATM drift of North Extension in the Tono Mine. As a part of this investigation, hydraulic tests were performed by means of the hydraulic measuring instrument, which had been developed by PNC Tono Geoscience Center. The purpose of this tests is to characterize the change in hydraulic properties of the EDZ caused by drift excavation using machine (boom header). The hydraulic tests were performed in the burials MH-1,2,3, in which hydraulic tests had been performed before the drift excavation in 1994. The test results indicate that the measured values of pore water pressure have decreased after excavation of the drift. The values ranged from -0.037 kgf/cm 2 to 0.039 kgf/cm 2 . The measured hydraulic conductivities ranged from 2.2*10 -11 cm/s to 9.1*10 -11 cm/s for mud stone and from 2.8*10 -9 cm/s to 2.4*10 -7 cm/s for conglomerate. The measured hydraulic conductivities for mud stone are below the lower limit of the instrument, and the change in the hydraulic conductivities for conglomerate is little. The hydraulic conductivities for conglomerate and mad stone (reference values) are interpreted. The change in hydraulic conductivities measured before and after excavation of the drift is insignificant. (author)

    'Geoscientific' research at Tono are developing site investigation and assessment techniques in geological environment. One of their important themes is to establish rational methodology to reduce uncertainties associated with the understanding of geological environment, which often exhibits significant heterogeneity. Purpose of this study is to identify and evaluate uncertainties associated with the understanding of geological environment. Because it is useful to guide designing effective site investigation techniques to reduce the uncertainty. For this, a methodology of the uncertainty analysis concerning the heterogeneous geological environment has been developed. In this report the methodology has also been tested through an exercise attempted in Tono area to demonstrate its applicability. This report summarizes as follows: 1) The exercise shows that the methodology considered 'variability' and 'ignorance' can demonstrate its applicability at three-dimensional case. 2) The exercise shows that the methodology can identity and evaluate uncertainties concerning ground water flow associated with performance assessment. 3) Based on sensitivity analyses, it is possible for the methodology to support designs of the following stage investigations to reduce the uncertainties efficiently.

Os resultados indicam que está em curso no PB um amplo mecanismo que visa reorganizar o paradigma verbal para um menor número de terminações verbais (Duarte, 1996, e que tal mecanismo é implementado através de concessões e restrições da organização gramatical. Assim, a redução do ditongo [ãw] átono na morfologia verbal se contextualiza na fonologia do PB através da redução segmental em posições prosodicamente fracas. Os verbos mais frequentes são afetados em maiores índices em decorrência da motivação fonética da redução segmental em contexto átono, e regularizando o paradigma verbal por nivelamento analógico

    2006-01-01

    Regional geologic settings of sandstone-type uranium deposits in Japan are firstly analyzed. The regional tectonic evolution characteristics of 'Green tuff region' and 'Non green tuff region' and their relationship with uranium mineralization are elaborated in depth. Based on those mentioned above, the uranium sources of sandstone-type uranium deposits in Japan are discussed deeply and the most favorable uranium sources are considered to come from the basement and the surrounding granites. Their intrusive epochs range from Later Cretaceous to Palaeogene (about 60 to 70 Ma ago). The characteristics of ore-bearing host rocks, matter compositions of the deposits, ore formation enrichment factors, the hydrogeologic conditions and so on are described by taking Ningyo-Toge and Tono deposits as examples. Finally, the prospecting measures for the palaeo-channel sandstone-type uranium deposits (basal type) are reviewed. (authors)

    Current status of regional hydrogeological studies on geological disposal including hydrogeological modeling using numerical simulators is reviewed in this report. A regional scale and boundary conditions of numerical models are summarized mainly from the results of the RHS (regional hydrogeological study) project conducted by Japan Nuclear Cycle Development Institute (JNC) in the Tono area. We also refer to the current conceptual modes of hydrology and numerical models of unsaturated zone flow at Yucca Mountain, Nevada, which is the arid site proposed for consideration as the United States' first underground high-level radioactive waste repository. Understanding behavior of a freshwater-saltwater transition zone seems to play a key role in the hydrogeological modeling in a coastal region. Technical features of a numerical simulator as a tool for geothermal reservoir modeling is also briefly described. (author)

Rock mass displacements of 1.46 mm and 0.67 mm have been measured at one meter (0.33D: blasting, 0.42D: machine, D: width of drift) from the walls of drifts excavated by the drill and blasting method and machine, respectively. Numerical analysis of rock mass displacements with Finite Element Method has been performed assuming an excavation disturbed zone. Measured and analysed rock mass displacements are consistent with each other for the drift excavation by the drill and blasting method. The excavation disturbed zone was narrower for the drift excavated by machine than for the drift excavated by the drill and blasting method. (author)

    Full Text Available En este trabajo analizaré la manera en que Montañez redefine el concepto de diva en su colección de cuentos Las divas de mi barrio. Arguyo que su redefinición valoriza la función de personajes femeninos que no sólo difieren físicamente de las ideas de belleza que se asocian con una diva sino que pertenecen a la clase trabajadora del país donde se desarrolla la acción. Por lo tanto, en estos cuentos se rinde tributo a otras formas de femineidad y de conocimientos que tienden a quedar excluidos por no ir a tono con las conductas y estéticas que afianzan el machismo.

    Full Text Available Un’operetta morale di Leopardi, la Proposta di premi fatta dall’Accademia dei Sillografi, adotta il linguaggio tecnico di un bando di concorso per proporre tre premi agli inventori di tre macchine umane perfette: l’amicizia, la magnanimità, la fedeltà coniugale sono gli obiettivi delle invenzioni scientifiche. Il tono serio cela in realtà la  polemica contro l’antropocentrismo e soprattutto contro l’ottimismo del suo tempo.  One of Leopardi’s Operette morali, Proposta di premi fatta dall’Accademia dei Sillografi, adopts the gergon of a competition notice to propose three prizes to the inventors of three perfect human machines: friendship, magnanimity, conjugal fidelity are the aims of scientific inventions.

    The TGDc-01 "PRA" (Ryazan State Instrument, Ryazan, Russia) tonometer is a new portable small-sized tonometer that measures intraocular pressure (IOP) through the eyelid. The purpose of this study is to assess the repeatability of the TGDc-01 IOP measurements by comparing them against those obtained with Goldmann tonometer and with those from Perkins applanation tonometer, Xpert (Reichert, Depew, NY) noncontact tonometer, and Tono-Pen XL (Medtronic Solan, Jacksonville, FL) digital tonometer. Fifty-eight right eyes of 58 young subjects were measured with each of the tonometers. Noncontact tonometry was performed first, followed by Goldmann and Perkins applanation tonometer (in random order), digital Tono-Pen XL, and finally TGDc-01 tonometer (sitting and supine position). Correlation analysis was used to evaluate the relationship between the Goldmann tonometer and the remaining tonometers used in this study. Plotting the difference between the methods against mean was also done to compare the tonometers. The hypothesis of zero bias was examined by a paired t-test. The 95% limits of agreement (LoA) were also calculated. TGDc-01 showed no statistical difference between the IOP measurements obtained in sitting and supine positions. A poor relationship between the TGDc-01 and Goldmann tonometer was found (r = 0.173; p = 0.001). Although the mean differences between Goldmann and Tonopen XL, Xpert, and TGDc-01 IOP measurements were statistically significant, the wider 95% LoA was observed when comparing the Goldmann and TGDc-01 tonometers. Computation of the 95% LoA resulted in a wide bias range when comparing the TGDc-01 with all the tonometers used in this study. The TGDc-01 "PRA" tonometer was not comparable with the other techniques used in the study. The wide dispersion range of the values obtained shows low repeatability of the TGDc-01 for screening purposes. These results could be because of the technique of measurement and/or interindividual variables.

  13. The effects of the modulus of the lens material on intraocular pressure measurement through soft contact lenses.

    To investigate the effects of the modulus of the lens material on the intraocular pressure measurement using the Tono-Pen XL applanation tonometer through soft contact lenses. Thirty eyes of 15 patients with myopia were evaluated. Intraocular pressure (IOP) measurements were performed using Tono-Pen XL directly over cornea, and subsequently through three soft contact lenses made up of different lens materials. All were -3.00 diopter soft contact lenses: lotrafilcon A with a low water content (24%) and high modulus (1.4 MPa) (CL-I), balafilcon A with a moderate water content (36%) and moderate modulus (1.1 MPa) (CL-II), and vifilcon A with a moderate water content (55%) and low modulus (0.79 MPa) (CL-III). IOP measurements through contact lenses were compared with each other, and with direct corneal measurements. The mean age of the patients (11 males and 4 females) was 26.86±5.62 years. All measurements obtained through CLs were significantly higher than the direct corneal measurements. The measurements through CLs differed by 4.61±0.54 mmHg (P=0,001), 2.9±0.46 mmHg (P=0.001), and 1.94±0.51 mmHg (P=0,003) for CL-I, CL-II and CL-III, respectively. In the paired comparisons of measurements through CLs, all comparisons were significant except the comparison of measurements through CL-II and CL-III (P=0.128). IOP measurements through silicone-hydrogel contact lenses with a high modulus and low water content were higher compared to the other contact lenses. While measuring IOP through CLs, the clinicians should consider the effect of the lens material and the features of the device used.

    The concentrations of fluorine (7.2-10mg/L) and boron (0.8-1.5mg/L) dissolved in groundwater pumped from shafts during excavation at the Mizunami Underground Research Laboratory (MIU), Tono Geoscience Centre, must be reduced to the levels below the environmental standards (fluorine:0.8mg/L, boron:1mg/L). Coagulation treatment and ion exchange treatment are applied for fluorine and boron at a current water treatment facility in MIU, respectively. A collaborative research on groundwater treatment for fluorine and boron was started by the Environment and Industrial Materials Research Division, Quantum Beam Science Directorate and the Tono Geoscientific Research Unit, Geological Isolation Research and Development Directorate in 2006. This is because the Quantum Beam Science Directorate has synthesized fibrous adsorbents with radiation-induced graft polymerization and applied them to collect rare metals dissolved in hot springs and sea water. Boron adsorbent synthesized by grafting showed higher removal rate than that of the ion-exchange resin. Additionally, the durability and the repetitive use of the boron adsorbent were evaluated to estimate the capacity of the boron adsorption. Therefore we produced a test equipment to do scale-up test of the adsorbent. Effects of flow rate and the repetitive use on the adsorption capacity of boron were investigated. As a result, it concluded that the adsorption capacity of the boron adsorbent did not change even when the flow rate increased from SV 50h -1 to 100h -1 . In addition, enough durability was confirmed for the repetitive use of the adsorbent. The adsorption capacity of the adsorbent was affected by pH of the groundwater especially in high alkaline range above a pH of 10. (author)

    The developmental study made at Tono Geoscience Center under the Earthquake Frontier Research Project since 1996 is reported for a brand new technology system called ACROSS (Accurately Controlled, Routinely Operated, Signal System invented at Kagoya University in 1994). Various technology elements have been combined together under a specific theoretical framework for the underground exploration and monitoring of structures and physical states. The ACROSS is essentially a spectroscopy of the underground space consisted of complex media subjected to environmental noise. The robustness against noise is devised by utilizing coherent elastic and electromagnetic waves with phase controlled very accurately. Demanded hardware technology has been developed successfully and know how has been accumulated for practical applications. Accurate synchronization of transmission and observation systems has provided us with reliable data on the tensor transfer function between the source and receiver, which is equivalent to Green function within a limited frequency range. Several examples of the field application are demonstrated by the test experiments at Tono Mine site. After the developmental works of 10 years, the ACROSS is brought to be a practical method applied to the remote monitoring of temporal variation of underground states at the Horonobe Underground Research Laboratory and also it is being applied to the expected focal region of the coming Tokai earthquake near Hamaoka in Shizuoka prefecture. Whereas ACROSS technology is not mature enough yet, it is shown to be a potential and versatile methodology applied even for the health monitoring of the construction such as building strongly coupled with the ground in addition to the underground study.

    This paper presents the development and functionality of a suite of applications which are being developed to support the geological investigations in the Tono URL. GEOMASS will include 3D geological modelling, 3D fluid flow and solute transport and 3D visualisation capabilities. The 3D geological modelling in GEOMASS will be undertaken using a commercially available 3D geological modelling system, EarthVision. EarthVision provides 3D mapping, interpolation, analysis and well planning software. It is being used in the GEOMASS system to provide the geological framework (structure of the tectonic faults and stratigraphic and lithological contacts) to the 3D flow code. It is also being used to gather the geological data into a standard format for use throughout the investigation programme. The 3D flow solver to be used in GEOMASS is called Frac-Affinity. Frac-Affinity models the 3D geometry of the flow system as a hybrid medium, in which the rock contains both permeable, intact rock and fractures. Frac-Affinity also performs interpolation of heterogeneous rock mass property data using a fractal based approach and the generation of stochastic fracture networks. The code solves for transient flow over a user defined sub-region of the geological framework supplied by EarthVision. The results from Frac-Affinity are passed back to EarthVision so that the flow simulation can be visualized alongside the geological structure. This work-flow allows rapid assessment of the role of geological features in controlling flow. This paper will present the concepts and approach of GEOMASS and illustrate the practical application of GEOMASS using data from Tono

    La atrofia urogonital causada por el estímulo deficiente estrogenito se manifiesta principalmente en la vagina, donde la mucosa sufre un adelgazamiento gradual que permite el predominio de células parabasales e intermedias propias del hipoestrogenismo, volviéndolo altamente sensible al trauma y la infección.

    Clínicamente se traduce en disminución de la humedad vaginal, sensación de llenura en el intróito, ruptura fácil de capilares vaginales con aparición de petequias, irritación, prurito y dispareunia.

    A nivel del endometrio se pueden presentar uno de los siguientes cambios: proliferación débil, atrofia senil, hiperplasia quística, hiperplasia adenomatosa, neoplasia omás raramente trastorno secretor; cambios que corresponden clínicamente a intervalos oligomenorreicos interpuestos por episodios hemorrágicos que finalmente terminan en amenorrea definitiva. En casos de sangrados postoriores ameritaría estudios anatomopatológicos de control obtenidos por biopsia o legrado uterino. Otros cambios que se presentan en el útero incluyen la pérdida de tono en sus ligamentos y elementos de sostén así comola disminución del cuello y su secreción.

    A nivel urinario la pérdida del tono uretral cursará con prolapso de la mucosa a través del meato, uretritis ahacteriana recurrente manifestada por poliaquiuria, disuria de ardor e incluso incontinencia urinaria de esfuerzo.

    Los cambios descritos anteriormente, hacen que la sexualidad femenina sea perturbada al presentarse dispareunia, disminuyendo de ritmo sexual y libido de la mujer haciendo su vida de pareja difícil y caótica. Se ha descrito también que la disminución de estrógenos produce ansiedad, depresión, tensión e irritabilidad al no permitir la disociación del triptófano de la albúmina para así formar sustancias tales como la hidroxitriptamina que participa en el mejoramiento del estado de ánimo.

Methods: All patients over the age of 18 years who underwent an LP in the emergency or neurological departments at the Tel Aviv Medical center for any reason between October 2007 and July 2010 were eligible to participate in this prospective observational pilot study. IOP was measured with the Tono-Pen XL while patients were in the supine position before undergoing LP. ICP was measured in the lateral recumbent position. ICP and bilateral IOP were measured, and the mean and maximum values of IOP were calculated. The association between ICP and each one of the four IOP measures was evaluated by the Pearson correlation coefficient. Results: Twenty-four patients (mean age 37.8 ± 15.8 years, ten males and 14 females were enrolled. The reasons for their requiring an LP were headache (19/24 patients, evaluation for hemiparesis (2/24, cognitive deterioration (1/24, and seizures (2/24. Nine had elevated mean opening pressure (>20 cm H2O, six had an elevated mean IOP (>20 mmHg, and four of these six also had an elevated opening pressure. There was no significant correlation between the ICP measurements and any of the IOP measurements. Conclusion: Handheld ocular tonometry has poor sensitivity and specificity for the prediction of increased ICP and is not an effective tool for screening for ICP in the ED or in the

    Abstract: This article sets out to explore the ways native speakers as well as foreign language learners use dictionaries and the strategies dictionary users adopt in the language acquisition process. The basis for this article is a corpus of six books (in chronological order Atkins (Ed. 1998, Nesi 2000, Tono 2001, Humbl? 2001, Sin-wai (Ed. 2004 and Thumb 2004 that look at both the usage of bilingual, monolingual and bilingualised dictionaries and the users' behaviour in the consultation process. Both the bilingual and monolingual dictionaries seem to be used independently, depending on whether the user wants to utilise them for comprehension, translation or production with regard to a foreign language. As pointed out in the literature on lexicography, some of these dictionaries, though they have undergone many changes over the years, still have serious limitations as learning tools, but the user's performance is also under investigation in empirical research, with the aim of optimising dictionary effectiveness as well as developing the language learner's skills.

    Full Text Available Currently, the existing information systems, and specifically the ERP, can not give adequate support to the management of manufacturing companies of ceramic tile, because, among other reasons, not to contemplate the existence of tone, size and quality within the same product. This feature, caused by the lack of homogeneity of the product (LHP, generates various problems in managing the product through the different business processes, such as, stocks management, order management, the production management, etc. Thus, it is necessary to develop an ERP solution that is able to manage adequately the ceramic product, including tone, size and quality. In this paper we analyze the requirements of the ceramic sector, in terms of product identification, and propose a data model to meet these requirements. The model arises as a basic guide for the development of vertical ERP solutions tailored to the ceramic industry.En la actualidad, los sistemas de información existentes, y en concreto los ERP, no pueden dar un soporte adecuado a la gestión de las empresas de fabricación de baldosa cerámica, debido, entre otros motivos, a que no contemplan la existencia del tono, calibre y calidad dentro de un mismo producto.

METHOD: Twenty seven infants were studied with positive cerebrospinal fluid (CSF culture for bacteria. We used the worse EEG result during acute phase of meningitis, and performed neurologic follow-up after discharge from hospital. Background cerebral activity was classified as normal or mildly, moderately, or markedly abnormal. Neurologic examination outcomes was classified normal, mild abnormalities, moderate abnormalities and severe abnormalities. RESULTS: EEG performed in the neonatal period during acute bacterial meningitis predicts adverse outcome early at age of 9 months, and had a significant correlation with cephalic perimeter and active tone alterations. CONCLUSION: Neonatal EEG is useful for predicting abnormal outcomes, especially cephalic perimeter and active tone abnormalities at 9 months of age in infants with bacterial neonatal meningitis.OBJETIVO: Medir la contribución del electroencefalograma (EEG neonatal y su correlación con el examen neurológico a la edad de 9 meses en recién nacidos con meningitis neonatal bacteriana.

    Topical atropine treatment is generally accepted to retard the progression of myopia, but it is associated with side effects such as photophobia and elevation of intraocular pressure (IOP). IOP measurements in children are challenging. The traditional applanation tonometry by direct contact with the cornea will require patient's cooperation. The rebound tonometer, using a dynamic electromechanical method for measuring IOP, shows good correlation with traditional tonometry. The purpose of this study is to evaluate the IOP of myopic children under atropine treatment using rebound tonometer and to compare the characteristics between rebound tonometry and applanation tonometry. This study is a prospective study measuring IOP by rebound tonometer in myopic children under regular low-dose atropine treatment. We recruited children with refraction error showing myopia over -0.5 D with 0.15%, 0.3%, or 0.5% atropine eye drops use every night or every other night for myopia control. Children with treatment duration of atropine tonometer (Tono-Pen XL, Reichert) and rebound tonometer (ICARE). The reliability of rebound tonometer was analyzed with percentage. Comparison of IOP between rebound tonometer and applanation tonometry was presented. The rebound tonometry was well tolerated by all participants and caused no complaints, discomfort, or adverse events. Totally 42 myopic eyes of 42 subjects were included in the study. The average age of these participants was 10 years old, range from 5 to 16. Median = 10 years old. The average IOP of the right eye by rebound tonometer was 17.4 ± 3 mmHg, and 17.1 ± 3 mmHg by applanation tonometry. Nearly 19%, 33%, and 24% of difference of IOP readings between rebound tonometer and Tono-Pen applanation are within 0 mmHg, 1 mmHg, and 1-2 mmHg, respectively. Rebound tonometry has good correlation with applanation tonometry and 76.1% of differences between two tonometers are <2 mmHg. The advantage of drop-free rebound tonometry has made it

    The concentrations of fluorine (7.2-10mg/L) and boron (0.8-1.5mg/L) dissolved in groundwater pumped from the shafts during excavation of the Mizunami Underground Research Laboratory (MIU), Tono Geoscience Center, shall be reduced to levels below the environmental standards for fluorine: 0.8mg/L and boron: 1mg/L. Coagulation and ion exchange methods are being applied for fluorine and boron, respectively, at the operating water treatment facility at the MIU. As well, collaborative research on groundwater treatment started in 2006 between the Environmental and Industrial Materials Research Division, Quantum Beam Science Directorate and the Tono Geoscientific Research Unit, Geological Isolation Research and Development Directorate on a novel method to remove the fluorine and boron. The Quantum Beam Directorate has synthesized fibrous adsorbents with radiation-induced graft polymerization and applied the adsorbents to collect rare metals dissolved in hot springs and sea water. The results of previous testing indicated that the adsorbent was able to remove more than 95% of the boron and fluorine and that performance of adsorbent for boron removal was better than the performance using ion-exchange resin. It was also apparent that the pH of groundwater had an influence on the performance of the adsorbent with respect to boron removal. Therefore we reran the recycling tests using groundwater from the neutralization tank at the groundwater treatment facility were repeated. The results indicated that the performance of the adsorbent using neutral groundwater for boron removal was higher than using uncontrolled groundwater. However the bed volume (BV) with recycled adsorbent decreased compared to first use. It is thought that sulfur added at the groundwater treatment facility was retained by the adsorbent despite elution, and affected the performance such that repeat usage resulted in decreased efficiency. In addition, it is considered that the goals established in the first

    Full Text Available Purpose: Although there are ample evidences for the effects (mostly decrease of intraocular pressure (IOP after the administration of atracurium and cisatracurium during general anesthesia in ophthalmic operations, no study has yet been done to compare their effects on both IOP and pupillary diameter (PD simultaneously. The aim of this study was to determine whether there is any difference between the effects of atracurium and cisatracurium on IOP and PD.Methods: Sixty patients with American Society of Anesthesiologists class I-II without history of previous eye surgery were studied in two randomly divided, double-blind groups. Following induction of anesthesia, atracurium (0.6 mg/kg and cisatracurium (0.15 mg/kg were administered to each group. IOP was measured by applanation tonometry (TONO – PEN ® XL and PD (COLVARD pupillometer at six sequential occasions, before induction of anesthesia, 2 and 5 minutes after induction and 2, 5 and 10 minutes after intubation prior to initiation of operation. Then they were compared to each other.Results: Trend of recorded IOP and PD values showed that there were no statistically significant differences between atracurium and cisatracurium according to their effect on IOP (p=0.125 and PD (p>0.137 during the course of study. Conclusion: It seems that both atracurium and cisatracurium have similar effects on IOP and PD before and up to ten minutes after tracheal intubation prior to surgical intervention.

En este artículo se utilizan métodos estilométricos para ratificar dichas afirmaciones y proveer nuevas visiones sobre la novela. Estos métodos incluyen, entre otros, el conteo de palabras y de frases, la construcción de árboles de consenso, el cálculo de la polaridad de las oraciones, e índices para cuantificar la complejidad y el nivel de concreción del texto. Los resultados indican la tendencia del autor a emplear, frecuentemente, palabras abstractas y referentes a objetos con los que se puede interactuar físicamente, para producir el efecto lingüístico propio del realismo mágico. Dada la importancia de los hallazgos, se plantean algunas ideas acerca de las implicaciones que la metodología puede tener en áreas de la psicolingüística y de la psicología cognitiva.

    The effects of earthquakes and active faults on the geological environment have been studied at the Tono Geoscience Center. The Hyogoken-Nanbu earthquake (January 17, 1995; M7.2) in Kobe and Awaji island caused significant changes in hydrology, involving a large amount of groundwater discharge in low-lying land and drastic water-table lowering (during only about 2-4 months) in elevated land near the epicenter. Simulation of the groundwater behavior in the vicinity of the Nojima fault was analysed to evaluate permeability enhancements. Calculated values such as water level changes were matched in a time series with the hydrological observed data in order to optimize this simulation model. Results indicate that the increase of hydraulic conductivity (5 x 10{sup -3} cm/s in weathered granitic rocks) and 1 x 10{sup -5} cm/s in fresh granitic rocks would produce a lowering of the water level at EL 180 m, and increase of discharge at less than EL 100 m, within four months after the earthquake. The study also suggested that the change in the hydraulic conductivity in the Nojima fault could not depend on the change in geological hydrology. (author)

    Test of the use of a measurement technique for the hydraulic conductivity of geological structures which act as flow paths or are impermeable to groundwater flow. In order to prove the value of flow-meter logging as an in-situ technique for detecting conductive fractures in granitic rocks, the method has been applied to a borehole near the Tono uranium mine, Gifu, Japan. This study in involved with detecting a conductive fracture and calculating the hydraulic conductivities. The results were as follows: (1) In a zone of groundwater inflow into the borehole, the hydraulic conductivity was calculated to be of the order of the 10 -3 - 10 -4 (cm/sec) from flow-meter logging. This value agreed with the results of a in-situ borehole permeability test carried out with a similar depth interval. (2) The study showed that flow-meter logging is effective for detecting the distribution of high conductivity fractures and calculating the hydraulic conductivity. (author)
