    A laboratory system named above has been developed to propel forward efficiently the efforts to develop medical welfare technologies through close coordination between medicine and engineering. Six laboratories are linked with each other in a network for the realization of an environment in which general support is extended to all the stages of equipment development from basic through clinical assessment. The biomedical engineering laboratory is constituted of various analyzing devices, and is capable of in vitro assessment of bioingredients. The therapeutic laboratory is provided with bioinformation/NMR (nuclear magnetic resonance) measurement equipment, animal surgical operation equipment, etc., and performs the assessment of test animals at the first stage of clinical assessment. The diagnostic laboratory acquires various image data necessary for the development of medical equipment at the same level as that of the site of clinical diagnosis. The intelligent surgical operation room takes in real-time diagnostic images while a surgical operation is under way and, at the same time, assesses surgical devices in the same environment as that of the surgical operation room. The medical information laboratory accumulates medical and image data from the other laboratories, and integrates the accumulated data. The data management center manages the laboratories in a unified way and enables comprehensive assessment and research. (NEDO)

    Discussions were given on airbags equipped in passenger cars as to methods of evaluating their deployment injuries. Airbag deployment injuries occur in occupants being out of position. In a driver`s seat, an injury may occur when an air bag deploys under a condition that a driver with relatively short body height gets closer to a steering wheel to maintain the driving posture. In a front passenger seat, if a child is not held in a restraint equipment, the child may be blown off into the vicinity of the airbag, whose deployment can cause an injury. According to the result of a test performed on a driver being out of position, the test method using a hybrid 3 dummy specified in the present ISO procedure may not necessarily be said to produce an evaluation on the worst case. In order to solve the problem, an ATD dummy which can measure bend in each rib independently would be used, or the hybrid 3 dummy must be measured in the worst set position. 4 refs., 8 figs.

    Product evaluation has been investigated from a viewpoint of compatibility with human life by considering human being as the subject of life. This report describes the investigation results. Product evaluation is defined as evaluating products on a consumer-oriented viewpoint and informing consumers of the evaluation results. According to a questionnaire survey with regard to daily living products, products in the low degree of satisfaction in their usage were electric tooth brush, video camera, electric rice jar, vacuum cleaner, and electric iron. Contents of dissatisfaction with these products were classified by aspect, i.e., human aspect regarding human body/recognition, life aspect regarding functions of products and how to use them, and sensitivity aspect such as appearance of products. Thus, points at issue were clarified. As regards the human aspect, incompatibility between the size/form of products and human body/posture, and recognition psychological incompatibility such as difficulty in understanding function or operation of products were pointed out. Establishment of a method for measuring and evaluating the human`s body functions and the compatibility with products, and necessity of the acquisition of human`s body characteristic data and the consolidation positions are also described. 4 refs., 42 figs., 30 tabs.

    This paper reports the survey results on R and D of solar cell evaluation systems in fiscal 1994. The performance/reliability evaluation subcommittee continuously analyzed technical issues and discussed solution measures from the last fiscal year. On development of performance evaluation methods, improvement of measurement accuracy for laminated solar cells is the study issue to be solved. Although laminated solar cells are measured by multiple light source solar simulator, difficult spectrum compensation causes measurement errors. Collection and analysis of data for determining atmospheric conditions, and outdoor measurement experiment under the atmospheric conditions for reference solar light were carried out. The study on incident angle characteristics of laminated solar cells clarified that the deviation from COS characteristics is 1.0% or less at an incident angle of 30{degree}. The study on generated energy in solar cell module level in field clarified that generated energy and generation efficiency are proportional to intensity of solar radiation. 1 tab.

    The research and development project for automatic sewing systems is aimed at establishing the techniques necessary for developing (automatic sewing systems) which efficiently produce diversified types of products in small quantities, to cope with various requirements, e.g., diversified consumers' needs and reduced cycle periods. This project covers R and D of the sewing preparation/processing, sewing/assembling, cloth handling, and system management/control techniques. The program for developing the total systems and elementary techniques draws the conceptual designs of their functions, performance and shapes, to outline the overall R and D project. The programs for the individual elementary techniques include studies on their basic functions and performance; design works from the basic designs to determine the specifications to the detailed designs of the devices to be developed; construction of the test units on a trial basis; and function confirming tests to confirm operability of the unit components and device performance, where these works are simultaneously implemented. This paper describes the interim results of evaluation of the elements developed for the elementary techniques, summarizing the results obtained so far. It is concluded that most of the targets of the R and D themes are sufficiently achieved by the end of FY 1987, and that the project can be now advanced to the next phase, construction of the test plants.

    In this study, seismic monitoring of injected gas in a carbonate reservoir was investigated using multidisciplinary approach which consisted of geological/reservoir modeling, reservoir flow simulation, rock physics and seismic modeling. A case study was conducted over Lower Cretaceous carbonate reservoir offshore Abu Dhabi. The gas saturation and reservoir pressure data were obtained from the reservoir flow simulation. The velocity data of dry rock samples under the various conditions were also obtained from rock physics study. These outputs were converted to the velocity model using Gassmann's equation. The calculated velocity from Gassmann's equation is well correlated with velocity from laboratory measurements. Therefore we con confirm that the Gassmann's equation is applicable to estimate the velocity of the gas saturated reservoir rock. Based on the velocity model, synthetic seismic sections before and after gas injection were constructed in order to verify the influence of gas flood. As the results, amplitude difference between the two synthetic seismograms was observed at top and bottom reflectors of the reservoir zone. This amplitude variation is caused by both gas saturation change and pressure change. Although further investigation is needed to detect the cause of the variation, this study indicates the possibility of seismic reservoir monitoring. (author)

    This report describes an interim evaluation method and a concrete evaluation method for projects promoted by the Agency of Industrial Science and Technology, and NEDO. As a result of the survey, a method of highly practical interim evaluation, concrete evaluation items, and evaluation criteria have been proposed by assuming that the projects are evaluated by the project evaluation department independent of the project promotion department. Long-term issues for constructing the evaluation system are also described. It is the most essential for the evaluation to fulfill the function of effective promotion of the following projects. It is also indispensable for the evaluation method and issues proposed in this report to communicate closely to project promoters and researchers, and to reassess the projects continuously. Continuous consideration for the feedback of evaluation process and the improvement of evaluation are significant for the long-term construction of system. 21 refs., 9 figs., 23 tabs.

    To evaluate the risk during longevity of reinforced concrete structure subjected to earthquake motions, called lifetime risk, damage and safety were estimated by means of the earthquake risk analysis and earthquake response analysis. For the earthquake risk analysis, historical earthquake data with relatively low accuracy were efficiently taken into account, to determine the annual mean generation probability against the earthquake motion strength in ten main cities. A new damage index with load hysteresis was defined as an anti-earthquake evaluation index where accumulative damage is taken into consideration. Assuming that the damage transits from `certain state` to `certain state` every time the earthquake motion generates at the noticeable place, damage transition matrix expressing transition probability was calculated by using the results of earthquake risk analysis and the accumulative damage index. The lifetime risk was calculated from the damage transition matrix and the earthquake motion generation probability, to evaluate the safety. 21 refs., 10 figs., 8 tabs.

    A comprehensive evaluation is made upon completion of the automatic sewing system research and development project. The project aims to achieve a 50% increase in productivity through effective use of a multiple-product/small-amount production scheme in small and medium sewing industries. The intelligent cloth inspecting machine (prior to sewing) in a laser-aided cutting system is as competent as the currently used sewing mill inspection system, and the resultant data are effectively utilized in the cutting process. As for the cutter, it is demonstrated that it is more than two times higher in cutting speed than a currently used laser cutting system; that it is sufficiently accurate in avoiding parts with flaws and in pattern matching; and that it is reliable in complying with process information provided. As for the flexible sewing system, it is acknowledged that it correctly recognizes information attached to cut parts and that it joins them with flexibility in response to changes in the material, pattern, or size. As for the high-technology assembling system, satisfaction is found in its automated 3-dimensional sewing of parts received from the previous stage and in its flow of production. As for the 3-dimensional flexible press, the quality after finish is found satisfying. The said systems are integratedly operated, and it is found that the goal of the research and development has been achieved. (NEDO)

    The research and development were reported on new refrigerants for compression type heat pumps. From 64 kinds of newly composed ether, CF3CF2OCH3 was developed as candidate compound substituting for CFC-11, and CF3CF2CF2OCH3 and (CF3)2CFOCH3 as those substituting for CFC-11. However, COP of the refrigeration has not been optimized. Global warming potentials were obtained by high-accuracy estimate guidelines. The new refrigerants have no chlorine and therefore no effects on the ozonosphere. Global warming effects also satisfied the present allowable values. There was no problem on human body toxicity in the short-term experiment. Costs of commercially production of the candidate compounds were trially calculated from reaction paths and chemical constitution formulae. Assuming that the raw materials are circulating on the market, plant/equipment investment, production volume, and production cost became 5 billion yen, 1000 tons/year, and 3500-6500 yen/kg in 3 persons/shift and 4 shifts, respectively. This is close to the allowable level which is ten times the CFC-12 price, 5000 yen/KG. The new refrigerants are expected to be fully commercialized in consideration of progress of the composition method and improvement of physical properties in the future. 115 refs., 37 figs., 102 tabs.

    This research and development project is aimed at development of the techniques which allow exploitation of manganese nodules occurring on deep sea bottoms (4,000 to 6,000 m deep) on a commercial scale, in order to secure stable supply of the non-ferrous metallic resource and improve general ocean development techniques. This project, established by the national project system, has been implemented cooperatively by the government, academic and industrial circles since 1981. Described herein are the interim results, summarized in the FY 1985. The targets of the phase for developing the individual techniques were set to develop the exploitation system design procedures, and to advance to the next phase by the end of FY 1985, where the consistent, integrated system is to be constructed and tested. The results obtained so far are satisfactory as a whole, both in the elementary techniques and their consistency. The simulations have been conducted, where various conditions are inputted to estimate the movement and exploitation characteristics of the system as a whole in the comprehensive ocean tests. It has been found that the nodule-collecting machine shows nonlinear tracking characteristics (i.e., movement different from that of the exploitation ship), and unsteady movements (i.e., repeated movements of rapid starting and stopping).

    Importance of the human behavior technology was paid attention to to get true safety and comfortableness of life through adaptability of products/systems to all humans. In consideration of the social and technological background, the human behavior recognition evaluation technology avoids economic/social losses caused by accidents and troubles and also provides the safe life environment for living people including the aged. Further, the gist of the project was proposed to make it clear that it can give a course of making things from a viewpoint of development of products dealing with individuals (personal fit) and can give new added values and contribute to heightening of international competitiveness at the same time. Development is made of technology of dividing concrete behavior patterns into types and also accumulating them in usable forms at the time of product design and in emergency and of technology of measuring all the time information on human behaviors in daily life without restrictions and on site. Supporting technology is developed for making the most of behavior information of users for product design and in emergency. Effects of the spread are also estimated. 76 refs., 13 figs., 9 tabs.

    In this paper, we propose the State Grouping scheme for coping with the problem of scaling up the Reinforcement Learning Algorithm to real, large size application. The grouping scheme is based on geographical and trial-error information, and is made up with state generating, state combining, state splitting, state forgetting procedures, with corresponding action selecting module and learning module. Also, we discuss the Labeling Based Evaluation scheme which can evaluate the opportunity of the state-action pair, therefore, use better experience to guide the exploration of the state-space effectively. Incorporating the Labeling Based Evaluation and State Grouping scheme into the Reinforcement Learning Algorithm, we get the approach that can generate organized state space for Reinforcement Learning, and do problem solving as well. We argue that the approach with this kind of ability is necessary for autonomous agent, namely, autonomous agent can not act depending on any pre-defined map, instead, it should search the environment as well as find the optimal problem solution autonomously and simultaneously. By solving the large state-size 3-DOF and 4-link manipulator problem, we show the efficiency of the proposed approach, i.e., the agent can achieve the optimal or sub-optimal path with less memory and less time. 14 refs., 11 figs., 3 tabs.

    Evaluation was conducted concerning R and D on magneto hydrodynamic (MHD) generation, with proposals made for the future R and D. As a result of the experimental operation and studies of the Mark 7 machine for MHD generation, a cold wall type generation channel was found promising in the long-term durability under MHD generation conditions. In addition, R and D was conducted on the exhaust gas control system that fulfilled an environmental standard, seed recovery method, grasp of seed coagulation state, etc. The R and D on element technologies were carried out along with the R and D of the Mark 7 and played a role in the backup of its experiment. MHD generation presents a large number of attractive characteristics, with its development expected in the future. However, it seems too early to immediately move on to the next step. Examinations should be made on such matters as comparisons with various kinds of new power generation systems using coal, trends in foreign countries particularly the U-500 project of the Soviet Union, the ideal system for more efficient development, and possibility of international cooperation.

    Research, development, and evaluation were made on seawater purification for the purpose of supplying inexpensive city water stably in the future. In the research of the high flow rate long-tube type multi-stage flash process, basic characteristics were identified by studying fluidity, heat transfer, deaeration, and decarburization by using a test plant with a capacity of 3,000 m{sup 3}/d. A number of findings were derived in carrying out demonstration studies by using a test module with a capacity of 100,000 m{sup 3}/d. Research on heat transfer pipe materials covered a wide area including copper alloys, titanium and aluminum alloys, and ferrous materials, where a prospect was obtained on materials which may be practically usable in the future as transfer pipes in large seawater purifying equipment. Research on a concrete evaporator body proved that it is more economical than steel evaporators, and has sufficient corrosion resistance even against high-temperature brine. Other activities included researches on effects of contaminated seawater, brine diffusion, byproduct utilization, and total systems. Social and economic evaluations were also performed. (NEDO)

    The paper reported the R and D of the membrane separation process introduction technology during a period of 1994 through 1998. The membrane separation technology is not associated with the phase change which requires large energy and expected to be an energy saving process. For the production of membranes required of high functions, the vapor deposition polymerization method was considered, and high order structure control of the membrane, control of adhesion and attachment, and control of orientation, and development of the high polymerization technology were required. For the high grade control of vapor polymerization, the substrate surface structure/quality were important. The molecular level analysis of the vapor deposition surface was also needed. Therefore, the paper took notice of STM (scanning tunneling microscopy), AFM (atomic force microscopy) and HREELS (high resolution electron energy loss spectroscopy) as surface atomic/molecular configuration analysis technology, and designed/fabricated and studied the high resolving power and high sensitivity analysis equipment using the analysis equipment which combined HREELS and STM and the analysis equipment using SFG (sum frequency generation) which can detect signals in the low frequency region. Making full use of the highest technology, technology was able to be developed for substrate surface analysis and surface reaction analysis technologies which become the basis of the high performance separation membrane fabrication technology by the vapor deposition polymerization method indispensable for introduction of the membrane separation process. The technology can be the base applicable to a lot of fields where surfaces and interfaces are concerned

    In order to assure stable supply of oil and natural gas resources, and achieve enhancement in ocean development technologies in general, development has been made on the subsea petroleum production system (SBPPS), which is effective in ocean floor petroleum production from oil fields at great depths (300 m or deeper), and can be applicable to continental shelves and continental slopes around Japan. The SBPPS consists of four sub-systems of shafts, pipelines, manifolds, and riser and oil storage, whose basic development targets were established for the total system. The system was given a conceptual design for the total system, and the above four sub-systems were designed according to the conceptual design. The experimenting devices of each system were fabricated on a trial basis while fundamental studies are being made on component technologies, and experiments were performed to verify basic functions of the sub-systems. Developments were made on such operation technologies as the system operation technology, production control technology, safety control technology, and maintenance and repair technology required to operate the SBPPS. On-shore and general off-shore experiments were carried out to verify the functions of the experimenting devices of each system, the comprehensive functions and the operation technology. Comprehensive evaluation was given on the above achievements from the technical, economic and social viewpoints. (NEDO)

    Described herein are the final evaluation results obtained by the 7-year R and D project, beginning in the FY 1976, established by the national project system for developing the techniques for treating urban solid wastes. This project has developed a semi-wet type selective crushing/sorting unit for sorting the wastes, and established the elementary techniques for recycling the wastes into various products, e.g., compost, pulp, combustible gases, aggregates, methane gas, or fuel oil. Two types of total treating systems, in which these elementary techniques are integrated, have been developed; one is to recover materials and the other energy. They can comprehensively, efficiently treat the wastes, adapting themselves to various situations. Pyrolysis which discharges reduced quantities of flue gases is adopted. Waste water is treated, mainly by biological treatment which is supported by the conventional methods, e.g., coagulation and adsorption. The cost estimation results indicate that the total system developed by this project can compare favorably with the conventional incineration system under general conditions, at a capacity of 300 t/d or more, when taking into consideration the secondary effects brought by the recycling/reutilization. This system is commercially feasible, when it meets with local characteristics, e.g., garbage collecting systems, market values of recycled resources, treatment/disposal conditions, and natural and social environments. This project has sufficiently achieved the original objectives. (NEDO)

    This research and development project is aimed at treatment of sewage, industrial waste water and the like at lower cost for reutilization, while efficiently producing methane or the like by the systems annexed to the water treatment systems with high-concentration bio-reactor systems incorporating separation membranes. The waste water types studied to be treated by these systems include sewage discharged in large quantities and waste water containing oil/fat and protein (low-concentration waste water), and starch-, alcohol and paper/pulp-containing waste water, and excrements (medium-concentration waste water). The project has found the optimum systems, by adequately configuring the separation membrane modules, and combining dissolution of suspended solid with methane fermentation reactors for selective treatment of organic substances; improved efficiencies of removing organic substances and producing methane by fermentation, and realized reduction in quantities of discharged sludge; and thereby established the bases for the new waste water treatment techniques. The reactor systems developed for water treatment are those based on biological removal of nitrogen. They greatly reduce treatment time to produce treated water of high quality. For treatment of sludge, the techniques have been developed to convert sludge into oil. These results are well applicable to various areas, e.g., sewage treatment, and food and pulp industries.

    Desktop video conferencing (DVC) system and its software were investigated. A test system was actually constructed. Based on the test results, its practical advantage and disadvantage were illustrated. The DVC system was constructed using general LAN, and operation experiments were conducted, as to research activity. From the interview with participants and analysis of conversation history, advantage and disadvantage of this system were clarified. Performance of the trial system was examined using practical LAN, to compare with the performance of commercial systems. When using LAN, the same problems were given. It was found that the DVC system can not substitute for the conventional real face to face meeting, but it is suitable for some communication styles, for example free participation meeting or collaboration based on the same objective, which has been hard up to this time. In addition, software was made as trial, by which reservation of meeting, announcement, and calling can be carried out. 26 refs., 6 figs., 5 tabs.

    This research and development project is aimed at development of the techniques which allow exploitation of manganese nodules occurring on deep sea bottoms (4,000 to 6,000 m deep) on a commercial scale, in order to secure stable supply of the non-ferrous metallic resource and improve general ocean development techniques. This project, established by the national project system, has been implemented cooperatively by the government, academic and industrial circles since 1981. Described herein are the interim results obtained by the FY 1984. The bases for development of the elementary techniques have been established for the comprehensive ocean tests. Bright prospects have been obtained to achieve the objectives, although there are some problems remaining to be solved. Interfaces between the sub-systems are being reviewed mainly by the persons in charge of the total system. No problem is foreseen in consistency of the individual components. The movement and exploitation functions of the test system are simulated and validated in detail, to develop the total system. It has been found by the simulations that the nodule-collecting machine shows nonlinear tracking characteristics (i.e., movement different from that of the exploitation ship), and unsteady movements (i.e., repeated movements of rapid starting and stopping).

The computers developed by this project met almost all of the specifications of the world's representative, large-size commercial computers, partly surpassing the world's machine. In particular, integration of the virtual memory, buffer memory and multi-processor functions, which were considered to be the central technical features of the computers of the next generation, into one system was a Japan's unique concept, not seen in other countries. The other developments considered to have great ripple effects are seen in LSI's, and techniques for utilizing and mounting them and for improving their reliability. Development of magnetic discs is another notable result for the peripheral devices. Development of the input/output devices was started to correspond to inputting, outputting and reading Chinese characters, which are characteristics of Japan. The software developed has sufficient functions for common use and is considered to be the world's leading, large-size operating system, although evaluation thereof largely awaits the actual specification results.

    A regression equation that can calculate the daily accumulated absorption heat of Trombe Wall was given, and the performance estimated chart of Trombe Wall in which the daily unit effect of Trombe Wall can be visually recognized was proposed. The absorption heat was multivariate-analyzed by two variables of solar radiation of that day and the previous day. The data obtained from simulation was used for analysis. The absorption heat was analyzed using the meteorological data at eight spots (Sapporo, Sendai, Niigata, Tokyo, Shizuoka, Kochi, Fukushima, and Kagoshima). In this case, the result of multivariate analysis almost coincided with the simulation result. A chart that predicts the absorption heat of Trombe Wall in eight cities from the daily accumulated global solar radiation of that day and the previous day was then created as the performance estimated chart of Trombe Wall. As a result, the solar radiation of that day little influences the absorption heat when the Trombe Wall increases in thickness. Conversely, the solar radiation of the previous day significantly influences the absorption heat. In future, an equivalent heat loss coefficient will be calculated from the performance estimated chart. 2 refs., 16 figs., 2 tabs.

For the basic technology of lamination, the SOI technology suitable for the three-dimensional circuit elements was developed, and it has become possible to manufacture high-quality multi-layered crystalline structure by means of annealing that uses laser and electron beam. In addition, a lateral epitaxial technology for solid phase was developed, and the base to be applied to the three-dimensional circuit elements was established. Furthermore, the technology to put thin film circuits together would be useful for high-density integration in the future. The three-dimensional circuit makes parallel processing in each segment possible, whereas a possibility was shown that the processing can be performed at much higher speed than before. Actually a prototype three-dimensional circuit equipped with functions for parallel processing and judgment processing was fabricated. The image pre-processing which has been impossible on the real time basis in the conventional two-dimensional integrated circuit was realized in a speed as fast as milli-second order.

Few data are available for environmental resistance of composite materials, whereas identification of environmental deterioration behavior and establishment of a environmental resistance evaluating technology are a significant issue in utilizing these materials as new materials for space, aeronautics, and marine applications in the future. The present research was taken up with objectives to elucidate deterioration behavior of composite materials exposed to special environment in the atmosphere and space and to establish methods for acceleration tests and environmental performance evaluation by using simulated environments equivalent to the natural environment exposure. The former period (fiscal 1982 through 1984) has investigated environmental conditions in the atmosphere and space, prepared standard test specimens, performed design on environmental devices simulating the environmental elements, as well as tests on deterioration due to environmental elements, and systematized the deterioration characteristics to establish composite test conditions.

    The first term has performed research and development placing emphasis on that 'the basic study on membrane separation is to be performed systematically to elucidate governing factors in membrane separation'. With respect to water/ethanol separation by using the penetration gasifying method, it was indicated that excellent separation performance can be exhibited by using natural polymers having sugar chain skeleton as a raw material, and by controlling the membrane structure by means of membrane manufacturing methods. For enhancement of performance in water selective permeation type separation membrane, it was shown experimentally that it is important to select a membrane suitable for the object of separation and a separation method that uses the selected membrane. Regarding the water/ethanol separation, it was shown theoretically that the penetration gasifying method can save more energy than the conventional distillation method, where the development target was presented. It was recognized that impregnation type liquid membrane using crown ether can separate amino acid optical isomers. High separation performance was obtained in carbon monoxide/nitrogen separation by using fluid carrier that uses cuprous iodine/1-methyl imidazole. (NEDO)

    A proposal was given on a new processing process to use Ni-group super alloy, and elucidation was given on super plasticity phenomenon by using non-destructive tests. The Ni-group super heat-resistant alloy Mod. IN-100 subjected to different preforms by means of extrusion was given a super plasticity test at 1,050 degrees C to derive total elongation and 'm' value. As a result, it was disclosed that a material annealed for one hour at 1,070 degrees C after extrusion of 70% at 1,100 degrees C possesses the maximum 'm' value in the vicinity of 2.0 times 10{sup -2}s{sup -1}. The largest key to the new processing method is to improve the nature of the material, in which the plasticity manifestation velocity is accelerated by ten times to the order of 10{sup -2}s{sup -1} as described above. In addition, forging of IN-100 was made possible by using the ordinary forging equipment with the use of two-fold measures. The measures consist of maintaining temperature of IN-100 during casting by heating the die material to about 600 degrees C, rather than keeping it at a constant temperature, and then packing IN-100 in S35C steel material to accommodate the temperature decrease during casting inside the S35C pack. Thus, a processing method was made practical, eliminating need of the forging process to compress and solidify powder itself, that is the extrusion process. (NEDO)

The basic target properties are heat resistance temperature of 250 degrees C or higher and tensile strength of 240 kg/mm{sup 2} or more for the FRPs, and heat resistance temperature of 450 degrees C or higher and tensile strength of 150 kgf/mm{sup 2} or more for the FRMs. This R and D program has been implemented for 8 years for development of raw materials, molding/processing techniques, quality evaluation and designs through information exchange and discussions of the experts in each area under integrated, close cooperation from raw materials to molding/processing. Most of the data indicate that the target properties and objects are satisfied or exceeded. It is therefore concluded that this project for the composite materials, extending for 8 years in 3 phases, has sufficiently achieved the initial objects. The unique techniques are incorporated in the raw materials, molding/processing processes, quality evaluation and designs. These efforts have produced the FRPs and FRMs of the world highest qualities. (NEDO)

    The research and development in the first term has searched widely different kinds of raw materials, elucidated electricity conduction mechanism, discussed processing technologies and evaluation methods. It also included molecule designing to develop new raw materials. A method for growing good single crystals of charge migrating complexes was developed, and (BEDT-TTF){sub 2}I{sub 3} crystals were found to manifest superconductivity at 8K under pressure of 1.3 kbar. In addition, elucidation was made on conduction characteristics of (TMTSF){sub 2}ClO{sub 4} being an induction superconductor, and on its superconduction mechanism. Polyacetylene films oriented at a high level by epitaxial polymerization were synthesized, the carrier hopping mechanism of polyacetylene was proposed, and the direction of increasing the conductivity was shown. It was discovered that cyanoacetylene is thermally polymerized at a relatively low temperature, turning into polymer with good orientation and easily into graphite. Polymeric intermediates soluble to polyparaphenylene vinylene (PPV) were synthesized, whereas these intermediates were found to have shaping and stretching properties, and conductivity of 2.8 times 10{sup 3}s/cm was obtained in PPV doped after the stretching.

    Described herein are results of evaluation of the developed excavators remotely controlled for highly deep submarine oil fields. The excavator system was designed to work at the target water depth of 200 to 250 m and excavation depth of 8,000 to 9,000 m, though not quite satisfactorily. There were several practical problems to be solved, e.g., those found in accuracy of reentry in the excavated section, cables connecting the driving equipment to the excavated section, and entangled hoses. The works were divided and system was configured in an attempt to secure all-weather type serviceability and to improve economic viability. The other major works included attempts to improve equipment functions and reduce manpower cost. Nevertheless, however, the construction cost was considered to be higher than expected, and no firm prospect was obtained whether the new excavator system was economically competitive with the conventional rig. The factors that pushed up the construction cost were various facilities needed by the new system with the separated excavation and driving sections, e.g., those facilities for helping the system land on the sea bottoms, material supply/storage facilities, and automated/unmanned facilities. The system failure and other items related to reliability are no clearly understood, making it difficult to compare it with the conventional rig in service factor. It was not adequate, therefore, to advance the next R and D phase as planned, and decided that the project was suspended to see the world development trends, because the clear plans for the future could not be drawn at that time.

    The research and development in the second term included development of raw materials, elucidation of electricity conduction mechanism, and development of methods to improve stability and a new processing method. Crystals of a large number of charge migrating complexes were grown to elucidate their electron properties and structures. A theoretical model was structured for the superconduction mechanism in the charge migrating complexes. Poly-p-phenylene vinylene-based polymers achieved {sigma}=1.1 times 10{sup 4}s/cm as a result of extension of soluble reaction intermediates. Poly-2, 5-phenylene vinylene doped with FeCl{sub 3} retained 10{sup 3}s/m for 165 days in nitrogen. Polypyrrole achieved 3.0 times 10{sup 3}s/cm in constant potential electrolytically oxidizing polymerization and extension at low temperatures. Polypyrrole doped with ClO{sub 4}{sup -} retained electric conductivity of 85% for 400 days in nitrogen. Electric conductivity of higher than 10{sup 5}s/cm was obtained by applying different kinds of doping into thin film and fiber formed graphite. The world's highest conductivity of 9 times 10{sup 5}s/cm was achieved particularly with discharge laminated and polymerized graphite doped with AsF{sub 5}. (NEDO)

This disclosure presents a possibility of preventing the light deterioration. New derivatives that show photochromism were synthesized, and thin films were produced by using the LB process. This indicates a possibility of producing the photochromic materials as the high multiplex recording material. With regard to PHB materials, an evaluation technology having spectrum resolution of the world's highest level was established and measurements were performed. Hole formation was verified for the first time in the world at the temperature higher than the liquid nitrogen temperature by using a PHB material of ionic porphin/polyvinyl alcohol systems.

This has allowed the understanding to be progressed on behavior of electrons in hetero interface or very thin films. It has also become possible to acquire new crystals that have band gaps and grid constants matching the performance of the elements. Regarding ultra-grid functional elements, new functional elements with the HET and RHET structures were made by utilizing the characteristics of the ultra grids, and performances of normal temperature operation and high speed operation were investigated. The ultra-grid structured elements have made it possible to embed ultra fine electrode structure into crystals by means of double hetero growth, and a possibility of Si-based PBT was demonstrated.

    This paper reports the survey results on evaluation of PV power generation in fiscal 1994. (1) On the evaluation technique of energy pay-back time, foreign trial calculation examples by integration method were surveyed. However, there were not many study examples, and the calculation basis of input energy was also ambiguous. The calculation result by input-output analysis in Japan gave the value more than that by integration method, pointing out that indirect input energy is essential. (2) On the evaluation technique of the degree of environmental contribution, CO2 emission of the PV generation system installed on ordinary housing roofs was calculated to estimate reduction of CO2 emission and cost. As a result, PV power generation as reduction measures against CO2 brought a little cost increase. (3) On the latent scale of PV power generation, it was estimated to be nearly 191GW although under no restriction. It was a considerably large value as compared with the current power generation capacity in Japan. 4 tabs.

    The fiscal 1999 results of survey and research conducted for the establishment of solar cell performance evaluation and reliability evaluation methods are reported. In the development of a super high fidelity (broad spectrum) solar simulator for cell evaluation, a prototype was tested for performance evaluation, and initially set values were achieved. In the development of a large-area module evaluation technology, the radiation area was increased to be 1.0m times 1.0m large. Outdoor exposure tests continued at 5 sites in Japan, 3 sites in Australia, and 1 site in Oman, and analyses and databasing were carried out for the outputs of various types of solar cell modules. As for the problem of coloring of fillers which are module constituents, coloring in the U.S. was attributed to high temperature and intensive insolation, and in Austria to an oxidation inhibitor. In the development of a photo-accelerated degradation testing method for Si-based solar cells, application of the cycled illumination test was found feasible. In this test method, an amorphous silicon solar cell retains 70% of the initial Pmax value even after the passage of a period equivalent to 30 years. (NEDO)

    Surveys and studies were conducted for establishing methods for evaluating solar cell performance and reliability. In the effort to develop basic technologies for the comprehensive evaluation of the performance of various types of solar cells and modules, an ultrahigh matching solar simulator and a large area solar simulator were built. The long-term exposure tests of solar cell modules kept on at 5 sites in Japan, 3 sites in Australia, and 1 site in Oman, and the databasing of the test data was planned. In the long-term evaluation of solar cell durability, investigations centered about module deterioration, where abnormal heat generation was observed, cause of increased resistance was inspected, and separation between the cell and the filler was examined. In the development of an accelerated photodegradation test method, it was found that the result of a light-dark cycle test with the ambient temperature varied agreed excellently with the results of outdoor exposure tests. It was consequently proved that the light-dark cycle test was a very promising candidate for an accelerated photodegradation test for a-Si solar cells. (NEDO)

    Research and estimation have been carried out on a mechanism to generate methane in paddy fields, which relates closely to global warming. For methane flux measurement, the chamber method was used. The result revealed that with paddy fields mixed with organic substances, methane generation was abundant in the order of raw rice straw mixed area > rice straw compost mixed area > chemical fertilizer mixed area. At the Ryugasaki test area, the raw rice straw and fertilizer mixed areas have generated methane annually at 27.0 gm[sup [minus]2] and 8.2 gm[sup [minus]2], respectively. With regard to soil types, the order was peat soil > gley soil > Kuroboku soil > light-colored Kuroboku soil, where the peat soil generated about 40 times as much of methane as the light-colored Kuroboku soil. As regards the influence from drainage adjustment, normally water-filled field, wet field, and dry field generated methane at 9.25, 4.79, and 0.34 gm[sup [minus]1] y[sup [minus]1], respectively. Amount of methane generated annually from paddy fields over the whole world was estimated at 22 to 73[times]10[sup 12] g. It was determined from the above facts that methane generation may be reduced if organic substance mixing and water in paddy fields are controlled properly. 8 refs., 5 figs., 1 tab.

    `Equivalent heat loss factor` used in the simplified load calculation method for the Trombe wall is a version modified to fit a solar house equipped with a Trombe wall. To compute the factor, it is necessary to input the quantities of Trombe wall inner surface absorbed/radiated heat for whose calculation the effect of the delay in solar heat storage by the Trombe wall has to be taken into consideration. The daily summation of the quantities of absorbed/radiated heat can be easily calculated using the day`s and the previous day`s insolation amounts. In this report, the hourly summation of the quantities of Trombe wall surface absorbed/radiated heat is performed by use of two variables which are the day`s and the previous day`s insolation amounts. In calculating the hourly summation of the quantities of absorbed/radiated heat, the daily summation of the quantities of absorbed/radiated heat is first calculated using the chart of predicted lines for the Trombe wall and, based on the data thus obtained, the quantities of absorbed/absorbed heat are divided and assigned to the respective hours and, as the result, approximations are obtained for the calculation of the hourly summation of the quantities of Trombe wall absorbed/radiated heat. A `time-dependent performance prediction curves for the Trombe wall` is proposed, which enables the visual comprehension of the effect of Trombe wall hourly units. 1 ref., 10 figs., 2 tabs.

    The objective of this paper is to evaluate a vulnerability function and a repair cost in terms of each structural damage level based on the damaged database of the 1995 Hyogoken Nanbu Earthquake. The seismic risk of a building in Kobe is calculated through the analytical results. As a result, the following are verified : 1. The expectation of vulnerability function, in which peak ground acceleration is taken for seismic intensity, is about 550 cm/s{sup 2} for minor damage, about 700 cm/s{sup 2} for moderate damage, and about 950 cm/s{sup 2} for major damage respectively. However, the coefficient of variation (C. O. V. ) is about 0.5 for all damage levels. 2. The expectation of repair cost per square meter is about 29000 yen for minor damage, about 60000 yen for moderate damage, and about 64000 yen for major damage respectively. However, the variation is very large, for example, the C. O. V. for repair cost varies from 1.2 to 1.6. 3. The seismic risk of a building in Kobe, that is normalized by new construction cost, is about three percent on condition that the design lifetime is assumed to be 50 years. (author)

    Described herein are combined production systems, capable of flexibly, quickly producing diversified types of machine members in small quantities in an integrated manner from raw stock processing to assembling/inspection. Development of the related techniques, including those for development of lasers of high output, has been implemented in an integrated manner for development of optical members, processing techniques and so on. The techniques developed by this project are expected to be applicable to various industrial purposes, because of their high synergistic effects. There was no oscillator of high output, when the project was started. This project has reduced device size and cost and improved their reliability, greatly contributing to expanded use of lasers. The solid-state lasers have been developed, not only for growing large-size crystals but also for transmission of light. The automation guidelines for assembling and inspection steps, which heavily depended on manual works, have been drawn. The machining functions have been improved by incorporating the processing techniques aided by lasers of high or medium output. One of the major problems involved in the conventional system is very time-consuming works required for establishing the software for the computer by which it is aided for operation. This problem has been solved by providing the modular structure machines developed by this project with flexibility of machining machine. (NEDO)

    This project was aimed at developing methods for producing basic chemicals from carbon monoxide and other stocks (the so-called C1 chemistry), in order to establish the techniques that could promote stable supply of basic chemicals from the new carbon resources in place of oil. It was a 7-year national project beginning in FY 1980, jointly implemented by the government, academic and industrial circles. Described herein are the overall evaluation of the results. There are several carbon resources other than oil, e.g., coal, natural gas, oil shale and tar sand. They are abundantly occurring, although unevenly, and various countries are developing these resources. They can be advantageously utilized as stocks for chemicals, after being converted into synthesis gases. In Japan, they have been efficiently developed cooperatively by national institutes, enterprises, academic circles and chemical industry, to produce the world's results, e.g., gas separation/purification techniques and new catalysts for new synthesis methods. This project was terminated because of the relaxed oil supply/demand situations and lowered crude prices in the middle of the 80's, which made stock conversion less urgent. (NEDO)

    Described herein is development of direct steel-making using high-temperature reducing gas. A light hydrocarbon fraction (boiling point: 230 degrees C or lower), produced by steam cracking of vacuum residua, is reformed into a reducing gas in the presence of steam, using heat to be supplied by a nuclear plant which produces high-temperature gases for various purposes. This reducing gas is then supplied to a plant for producing reduced iron. This project has established basic techniques for designing, constructing and operating a direct steel-making pilot plant, to be connected to a 50 MWt high-temperature gas test furnace. The closed iron-making system and greatly reduced SOx emissions to several fractions of the current level are some of the expected effects. The environmental impacts of the high-temperature gas furnace will be on a level with those associated with a light-water reactor. Cracking and gasification of vacuum residua, which has found limited purposes so far, should expand its applicable areas and reduce dependence on fossil resources, leading to diversification of energy sources. The overall thermal efficiency of the high-temperature gas furnace is expected to increase to at least 60%, because its high-temperature gases of around 1,000 degrees C can be used for heating processes, and the waste heat can be further used for generation of steam for power production.

    With relation to some global energy systems of which viability is predicted in the future, an evaluation was conducted from the viewpoints of economical efficiency, energy balance, CO2 emission, etc. The fossil fuel CO2 capture system, the conventional thermal power plant added with CO2 recovery/treatment facilities, is expected to reduce approximately 70-75% of the CO2 emission. The fossil fuel decarbonated hydrogen system, which decarbonates fossil fuels, recovers/treats CO2 at the place of fuel supply and uses as hydrogen, is of poor practical application from an economical point of view. The fossil fuel methanol synthesis system, which synthesizes methanol from fossil fuels at the place of fuel supply, generates electric power and recovers/treats CO2 with the methanol, is large in energy loss and CO2 emission and low in overall efficiency and CO2 reduction effect at the time of methanol synthesis. The renewable energy hydrogen system is an ultimate system with no emission of CO2, though it costs much. 110 refs., 83 figs., 107 tabs.

As a result, the concrete (promotion objectives), including those related to mechanical characteristics, have been almost achieved. For development of the highly functional FRP materials, the R and D efforts are directed to improvement of their moldability while satisfying the requirements of high functions, e.g., resistance to heat, leading to development of the basic techniques for epoxy resin-based intermediate materials. These results indicate possibility of commercialization of highly heat-resistant polyimde resin-based and novel resin-based intermediate materials. The results of the novel molding/processing methods, taken up in the second phase project as the ones which use no autoclave, are rated that they are developed to suggest possibility of the eventual commercialization, although the products they give are not always showing sufficient mechanical properties.

    A Micro Turbine Sensor has been developed to measure fuel injection quantity and injection rate. Previous reports described results of experiments on the MTS which were carried out under steady and unsteady flow conditions. The MTS has been improved in shape of a holder tip and a detecting procedure for rotating speed of a turbine. As a result revolution speed of the turbine increased 18% over the conventional type holder under steady flow condition. Furthermore the measurement resolution of the MTS came up to about 2(mm{sup 3}/pulse) at 20(mm{sup 3}/stroke) under intermittent spray conditions using fuel injection pump. 11 refs., 11 figs., 1 tab.

    Concerning the research and development of environmentally-friendly combustion technologies that had been conducted for six years beginning in 1992, analysis and discussion were made by a special committee dedicated to the evaluation of the efforts, and the outcome is stated. In the study of zeolite-base catalysts, a highly active catalyst was developed which assumes a multilayer structure of mordenite, etc., with titanium introduced thereinto using an NO-selective reducing catalyst. As for metal complex oxide-base catalysts, various catalysts high in activity were developed, based on saponite which is a laminar, clayey compound. As for alumina-base catalysts, details were learned of the reaction mechanism and catalysis activation sites and, helped by the findings, a silver-supporting alumina catalyst was produced. In the study of direct decomposition type NOx removing catalysts, a success was achieved in causing NO to be decomposed with high selectivity in an oxygen atmosphere by use of new-type electrodes, functional layers, and solid electrolytes. In the field of catalytic combustion, a PdO-Pt/Ba-Al2O3 catalyst was developed, which is to serve for a hybrid type catalytic combustion method. 19 refs., 112 figs., 25 tabs.

    This paper describes the achievements in fiscal 1992 in the field tests on fuel cell power generation systems. The three locations subjected to the present analysis are all installed with 50-kW systems, whereas power generation efficiency of around 35% such as 35.3, 34.2 and 34.6% was obtained when the systems were operated at the rated output. When the load gets to below a certain load band (about 30 kW), the power generation efficiency decreases proportionately with the load. The overall efficiency including heat supply was 77.8, 70.7 and 80.3% respectively at about the rated output, showing a trend that the higher the thermal efficiency, the higher the overall efficiency. The case of generating both electric power and heat simultaneously has higher efficiency than the case of heat supply alone. The contribution rate of the fuel cell as a base load was 2.8, 4.6 and 13.6%, respectively. The system with as high value as 13.6% takes a power load following type operation mode, in which power is generated during a time band with large load during weekdays, and no power is generated at nighttime and in holidays when load is smaller, playing a role of peak responding power supply. Only one trouble has occurred in an auxiliary generator in the heat recovery system. (NEDO)

    Ab initio MO calculations of 1-phenyl-1H-tetrazoles were carried out, in order to explain a substituent effects on its high thermal stability and to estimate the thermal stability of the other tetrazoles. Similar to 1H-tetrazole, five bonds in the tetrazole ring have intermediate lengths between single and double bond lengths. Phenyl and tetrazole rings are not both on one plane showing no interaction. Three indexes addopted as a measure of thermal stability indicate that the more equal the bond lengths of the ring are and that the bigger the stabilization energy by ring formation is, the more thermally stable they are. It is found out that there is the relationship between the thermal stability and the ring charge. That is, the more negative the ring charge is, the more thrmally stable the tetrazole is. Also, there is a good relationship between the thermal stability and the energy level of orbital of which orbital is an anti bonding type with respect to the N3-N4 bond. The higher the energy level is, the more thermally stable the tetrazole is. (author)

    This project was aimed at developing methods for producing basic chemicals from carbon monoxide and other stocks (the so-called C1 chemistry), in order to establish the techniques that could promote stable supply of basic chemicals from the new carbon resources in place of oil. It was a 7-year national project beginning in FY 1980, jointly implemented by the government, academic and industrial circles. Described herein are the overall evaluation of the results. There are several carbon resources other than oil, e.g., coal, natural gas, oil shale and tar sand. They are abundantly occurring, although unevenly, and various countries are developing these resources. They can be advantageously utilized as stocks for chemicals, after being converted into synthesis gases. In Japan, they have been efficiently developed cooperatively by national institutes, enterprises, academic circles and chemical industry, to produce the world's results, e.g., gas separation/purification techniques and new catalysts for new synthesis methods. This project was terminated because of the relaxed oil supply/demand situations and lowered crude prices in the middle of the 80's, which made stock conversion less urgent. (NEDO)

    The paper described a study made during 1995 through 1998 on the application of 3D woven C/C composite materials to machine parts. The materials are large in rigidity, small in specific gravity, excellent in specific rigidity, and suitable for high speed rotation. They are excellent in heat resistance/dynamic reformation and expected as materials which can exceed limits of the existing steel for machine parts. However, to use them as machine parts, a possibility of high precision cutting is required. Therefore, a study was made on metal multi-layer membrane coating to C/C composites. Pitch-system high-elastic carbon fibers were made a 4-directional material by orienting horizontally in 3 directions at 120 degrees per plane and also orienting vertically. Various materials such as W, Mo and WC were coated by the laser assisted plasma hybrid spraying method. High adhesion coats with little pore were obtained. Multi-directionally woven C/C composites used to be poor in surface precision workability, but the problem was able to be solved by coating surfaces with metal layers and metal multi-layer membranes. The application is expanded not only to polygonal mirrors (for laser printing machine) and milling spindles, but largely to machine parts. 11 figs., 1 tab.

    The project aims to establish basic technologies for the mass culture of cells by utilizing the features of animal cells, which will enable a large, stable supply of fine chemicals such as highly functional physiologically active proteins whose industrial production the conventional technique of synthesis fails to realize. For this purpose, efforts are exerted to select cells which are capable of producing target substances, to breed highly productive strains, to develop a serumless medium that satisfies demands for an all-purpose feature and heat sterilization, and to develop technologies of high-density culture and effective refining, etc. Some DNA (deoxyribonucleic acid) recombination technologies are also resorted to. As the result, a high-density culture of 2 times 10{sup 8} cells/ml has become available. Production is now feasible of various differentiation-inducing elements such as monoclonal antibodies with anti-HB virus activity, DIF, etc. Furthermore, cooperation with the Tsukuba University leads to the discovery of a novel vasopressor peptide (endothelin). The heat sterilization accepting serumless medium, which is put to practical use as the first of the kind in the world under this research and development project, contributes to the advancement of basic studies about cell biology.

    Efforts are put into the study of direct iron making for use in a closed system where heat energy from a multi-purpose high-temperature gas furnace expected to be developed in the near future will be utilized for iron making. The researches, carried out for the establishment of technologies necessary for designing, building, and operating a pilot plant dimensionally suitable for connection to a 50MWt multi-purpose high-temperature gas furnace, cover the plant total system, a high-temperature heat exchanger, ultrahigh-temperature alloys, high-temperature insulating materials, a reduced gas generating unit, and a reduced iron making unit. When the effort is evaluated as a whole, it is found that the newly developed system is effective in preventing pollution, emitting but 0.1Nm{sup 3} of SOx per 1 ton of crude iron against the 0.4-0.9Nm{sup 3} emitted by a blast furnace/converter iron making mill. It is also found effective in reducing fossil fuel dependence and in enhancing energy source diversification. When it comes to energy conversion efficiency, furthermore, it is shown that the new system achieves a rate of 60% or more while only approximately 30% is attained by light water reactor power generation and approximately 40% by a high-temperature gas furnace.

    This paper reports the result obtained during fiscal 1994 on characterization and control of surface/interface recombination velocity of crystalline silicon thin films. To optimize design and manufacture of solar cells, it is necessary to identify correctly resistance factor (or doping) of bulk of materials, bulk minority carrier life, and recombination velocity on surface, passivation interface and electrode interface. A group in the Hokkaido University has been working since a few years ago on development of non-contact and non-destructive photo-luminescence surface level spectroscopy (PLS{sup 3}). A new non-contact C-V method was also introduced. Using these methods, basic discussions were given on possibility of separate measurements on surface/interface and bulk characteristics of solar cell materials. The PLS{sup 3} method and the non-contact C-V method were used for experimental discussions on evaluation of silicon mono-crystalline and poly-crystalline materials. Discussions were given on separate evaluations by using the DLTS method. 10 figs., 2 tabs.

    Studies are conducted to establish the methods of testing and evaluating applicability of ceramic-metal bonding for ceramic gas turbines, and the FY 1993 results are reported. The program involves measurement of residual stress by the X-ray method and durability tests for the joints of silicon nitride and austenitic stainless steel with copper as the intermediate layer, and analysis and classification of the strength/durability test results obtained until the previous fiscal year by the finite element method, to evaluate applicability of the joining. For the strength characteristics at high temperature, the test pieces tend to lose strength at 400 degrees C and higher, and high-temperature strength as cross-head displacement speed increases. The upper limit of bending strength at room temperature decreases as number of thermal cycles increases. The test pieces subjected to thermal cycles have a higher bending strength at high temperature than at room temperature. The results of the two-dimensional plasticity analysis of the residual stress in the joint by the finite element method are in good agreement with the results by the X-ray method. (NEDO)

    In a servo PD (positive displacement) flowmeter for oil, a differential pressure transmitter detects difference in pressure between the PD flowmeter input and output ports and a rotor is driven by a servo motor so that the pressure difference between before and after the PD flowmeter rotor will be zero. The design enables high-accuracy measurement across a wide range of flow rates and is not easily affected by the surrounding physical conditions such as viscosity and density. For the development of such a flowmeter, it is necessary to develop a rotor that rotates smoothly free of locking in a steady and uniform flow, to build a visualized model that enables the analysis of flow inside the flowmeter which in turn will enable the determination of optimum differential pressure detecting ports, and to connect a newly developed servo mechanism to the thus determined ports. As the result of the research, a servo PD flowmeter is developed, which is a 50mm diameter prototype employing the Invoflex tooth form which is the waveform for a rotor suitable for a high performance flowmeter. Placed in a generally used oil flow calibration liquid, which is gasoline, kerosene, or the like, it covers a flow rate range of 1:10 and reads with an accuracy of {+-}0.1%. It remains stable in performance and suffers but a little change with the passage of time. (NEDO)

    For the effective utilization of solar energy at houses, a heating system using an air hybrid collector (capable of simultaneously performing heat collection and photovoltaic power generation). As the specimen house, a wooden house of a total floor area of 120m{sup 2} was simulated. Collected air is fanned into a crushed stone heat accumulator (capable of storing one day`s collection) or into a living room. The output of solar cell arrays is put into a heat pump (capable of handling a maximum hourly load of 36,327kJ/h) via an inverter so as to drive the fan (corresponding to average insolation on the heat collecting plate of 10.7MJ/hm{sup 2} and heat collecting efficiency of 40%), and shortage in power if any is supplied from the system interconnection. A hybrid collector, as compared with the conventional air collector, is lower in thermal efficiency but the merit that it exhibits with respect to power generation is far greater than what is needed to counterbalance the demerit. When the hybrid system is in heating operation, there is an ideal heat cycle of collection, accumulation, and radiation when the load is light, but the balance between accumulation and radiation is disturbed when the load is heavy. 4 refs., 8 figs., 3 tabs.

    This project is aimed at stable supply of the stocks for the petrochemical industry to cope with the keenly felt depletion of oil resources in the long run and price hikes, and promotion of effective utilization of high-sulfur heavy oil fractions difficult to desulfurize, thereby promoting prevention of pollution. The techniques have been developed to economically produce high-value products, e.g., olefins and aromatic hydrocarbons, by thermally cracking abundant stocks, e.g., vacuum residue. A 120 t/d fluidized bed pilot plant with coke as the heat medium was constructed to develop various techniques, e.g., those for controlling coking, decoking, quenching cracking products, and controlling coke particles as the heat medium, to realize stable, continuous operation for extended periods of at least 1,000 hours. The techniques have been also developed for effective utilization of heavy oils as by-products containing sulfur at high concentrations. Economic viability of the process is considered to be on a level with that associated with naphtha cracking at present, when an intermediate base vacuum residue is used as the stock material. It will be sufficiently competitive with naphtha cracking with all types of heavy oils as the stock materials, including intermediate base vacuum residue, in an intermediate term. (NEDO)

    This paper studies the method of predicting and evaluating the motion sickness incidence from subject`s facial expressions during the whole-body exposure to oscillations. The facial expressions are recorded with a video camera which can measure them without invasion physiologically and mentally. Facial parameters, which are considered to relate to the motion sickness incidence, are selected, measured and analyzed quantitatively, and a method of evaluating the motion sickness incidence objectively from the facial expressions is proposed. Three facial expression parameters now selected to evaluate the motion sickness incidence are brow width, eye opening and mouth opening. It was clarified that the motion sickness incidence could be expressed joining the above parameters together. This paper consists of three sections, viz. Oscillation experiment for ride-quality evaluation, Measurement and analysis of facial expressions, and Modeling for evaluating facial expressions. 11 refs., 5 figs., 5 tabs.

    Discussions and evaluations have been performed on the safety and durability of the device installed with inverter to protect grid connection being an important device in the photovoltaic power generation system. This paper summarizes the achievements in fiscal 1996. The current fiscal year performed data collection and long-term continuous operation according to the durability test program for the device installed with inverter to protect grid connection, as the continuation from the previous fiscal year. In the electrical characteristics, although no large changes have been found in AC overvoltage and AC undervoltage, instability was observed in the detection level. With regard to temperatures in different components, the temperature rise has become nearly the same as in the maximum output continuous operation as a result of the repetition of the operation and shutdown, whereas the influence on the electrical and thermal stresses have increased. Particularly, when temperature rise in the AC side noise filter was given observation, the measurement of conductive high-frequency terminal voltage showed a value higher by several ten dB than in the previous fiscal year. The current fiscal year has gone farther to starting the measurement of noise electric field intensity as the base of electromagnetic interference. (NEDO)

    Discussions and evaluations have been performed on the safety and durability of the device installed with inverter to protect grid connection being an important device in the photovoltaic power generation system. In discussing the durability test items, electrical property changes were observed on AC overvoltage, AC undervoltage, frequency rise, and frequency fall, as the continuation from the previous fiscal year, in order to evaluate temperature rise in different parts due to lapse of operation time and the effects of thermal stress in each component on the stress of the entire product. Furthermore, verification of single operation detecting function, tests on sudden input power change, sudden grid voltage change, and measurement of conductive high frequency terminal voltage were conducted in addition to the above observations. In discussing the durability test methods, repetition of operation and shutdown during the rated operation was adopted in place of the simulated operation using variation in the insolation having been discussed in the previous year. As a result of the tests, no noticeable changes were recognized from the evaluation result after a lapse of 5,000 hours from the start of the operation, as compared to those after the aging operation.

    Tests and discussions have been performed on the safety and durability of the device installed with inverter to protect grid connection, being an important device in the photovoltaic power generation system. The particularly important requirements demanded in the device were specified as maintenance of electric power quality, coordination with the protection system in the grid side, and assurance of safety of personnel and facilities. The current fiscal year has performed operation corresponding to that in the actual field for 20 years in total, and the evaluation tests on electrical characteristics and electric power quality. This paper summarizes the achievements in four years including the results available up to the previous fiscal year. Although no large change has been identified in the electrical characteristics, variance has been found in the detection time of overvoltage in the grid side. With regard to the electric power quality, the value has exceeded 89 dB as the determining condition for the certification test in the conduction interfering waves of 5 kHz to 10 kHz. In addition, it was confirmed that the conductive high-frequency noise terminal voltage in the grid side after the repetition of operations and shutdowns tends to increase according to the operation lapse time.

    In the research and development of photovoltaic power generation system evaluation technology, great progress has been achieved in performance improvement and cost reduction as far as constituent devices such as power modules and inverters are concerned. In the designing of systems, however, quantitative elucidation of loss and power reduction factors remains insufficient. Under the circumstances, several types of photovoltaic power generation systems expected to be put to practical application in the future are taken up, test facilities are constructed which simulate them, and data are collected. The thus-collected data are utilized for research and development of evaluation techniques necessary for the improvement of photovoltaic system efficiency, such as design parameter quantification, databasing and utilization thereof, and simulation technologies, for the establishment of technologies for optimum designs and optimum operations. The data book accommodates data, arranged in an easy-to-use fashion, collected about verification test facility (interconnected systems, independent systems, and water pump systems) operation, weather conditions, and residential photovoltaic power generation systems.

    This paper discusses life evaluation on phosphoric acid fuel cells of urban energy center type for regional energy supply and on-site type to be installed in buildings. Operation characteristics tests and disassembly checks allow to identify factors for voltage decrease, and estimate the life therefrom particularly if the voltage decrease is caused from catalyst activity. The time before 10% decrease value is reached is now about 40,000 hours. The creep analysis method that has been developed recently can predict deformation in full-size reformers nearly exactly, and is effective in operating the reformer and evaluating the life at the design stage. Creep buckling is the critical value, which is caused by ecliptic deformation of internal tubes in the second catalyst layer. In a heat exchanger for fuel gas preheating, carbon in the reformed gas is carbonized and deposited due to catalytic action of nickel in the brazing material that bonds plates and fins in the heat exchanger. Iron also has a possibility of performing catalytic action. In the on-site type 1,000-kW class fuel cells, no structural problems have been presented even after the operation has been stopped. In order to extend time interval between phosphoric acid supply into the cells, it is necessary to reduce difference in the remaining phosphoric acid amounts in the stack lamination direction and in the cell flat surface.

    Receiving subsidies from MITI, NEDO carried out this project in fiscal 1995 and 1996 as a joint research with Technology Research Association for Phosphoric Acid Fuel Cell Power Generation System and others. The project aimed at developing the accelerated test method which can evaluate in a short time the cell life of phosphoric acid fuel cells (PAFC) and the lowering of characteristics. The accelerated test method of PAFC life is thought to be a tool indispensable for the promotion of commercialization, but the accelerated test method like the usual material evaluation has not yet been established. To solve this problem, procedures were developed to rationally plan the accelerated test on short stacks of full scale based on the small cell test data. Here, to rationally estimate the operational state under actual conditions based on the data on the accelerated test, it is necessary to fully understand the mechanism of deterioration of PAFC. By conducting in parallel the element study for the basic elucidation of cell deterioration phenomena, obtained was the useful information/knowledge which back up the results of the accelerated test scientifically. 168 figs., 33 tabs.

    The first term has performed research and development placing emphasis on that 'the basic study on membrane separation is to be performed systematically to elucidate governing factors in membrane separation'. With respect to water/ethanol separation by using the penetration gasifying method, it was indicated that excellent separation performance can be exhibited by using natural polymers having sugar chain skeleton as a raw material, and by controlling the membrane structure by means of membrane manufacturing methods. For enhancement of performance in water selective permeation type separation membrane, it was shown experimentally that it is important to select a membrane suitable for the object of separation and a separation method that uses the selected membrane. Regarding the water/ethanol separation, it was shown theoretically that the penetration gasifying method can save more energy than the conventional distillation method, where the development target was presented. It was recognized that impregnation type liquid membrane using crown ether can separate amino acid optical isomers. High separation performance was obtained in carbon monoxide/nitrogen separation by using fluid carrier that uses cuprous iodine/1-methyl imidazole. (NEDO)

    This paper describes the achievements in fiscal 2000 from the WE-NET Phase II for Task-1. Technologies drawing attentions relate to fuel cell driven automobiles and hybrid automobiles in the field of utilizing hydrogen derived from reproducible energies and fossil energies, and fuel cell co-generation and micro gas turbine co-generation in the field of electric power generation. Hydrogen reformed from gasoline on board the automobile as the fuel for fuel cell driven automobiles, hydrogen as a by-product of coke furnace off-gas (COG), and reproducible energy hydrogen have the same fuel consumption performance as in the hybrid automobiles. Particularly the COG is low in cost, and has large supply potential. Liquefied hydrogen is as promising as compressed hydrogen in view of the cost for automotive hydrogen supply stations. What has high economic performance as the self-sustaining systems for islands are photovoltaic and wind power generation, and the system using hydrogen as the secondary energy. Since much of the reproducible energies is used for electric power demand in Japan, the by-product hydrogen and the reformed hydrogen in an amount of 9.3 billion Nm{sup 3}/year would take care of majority of the demand in view of the short time period. For a longer time span, hydrogen originated from the reproduced energies in the Pan-Pacific Region should be introduced. (NEDO)

    With the aim of formulating a strategy for introducing hydrogen, assessment was carried out on the energy consumption, environmental impacts and cost effiectiveness concerning various hydrogen utilization systems. In regard to soda-electrolysis by-product hydrogen and coke-oven by-product hydrogen, hydrogen supply capacity and cost effectiveness were evaluated. As a result, the two systems were found to have an annual hydrogen supply capacity of 11.52 GNm{sup 3} in total. As to the cost effectiveness, transportation by pipeline was 34 yen/Nm{sup 3}-H{sub 2} in the case of soda-electrolysis by-product hydrogen, and 40 yen/Nm{sup 3}-H{sub 2} in the case of coke-oven by-product hydrogen. An estimated cost of power generation showed 56 yen to 67 yen/kWh in such a system on remote islands as replacing diesel power generation by wind power generation, storing part of the electric energy produced in the form of hydrogen through water electrolysis, and using it as fuel for power generation by the fuel cell unit if wind conditions are unfavorable. Power generation cost on remote islands at present is sometimes in excess of 50 yen/kWh; therefore, this combined system showed promising results. The cost of using wooden biomass was estimated to be 51,000 yen/TOE , whose competitiveness is uncertain. (NEDO)

The R and D themes are selected to develop alloys superhighly resistant to heat, heat-resistant/high-rigidity and light/high-rigidity by controlling their crystals. Development of the basic techniques for these materials is of high significance, and highly rated. The efforts in the first-phase R and D project are aimed at designs of a total of 12 types of single-crystal alloys by the computer-aided alloy designing techniques, production of these alloys on a trial basis, and evaluation of their characteristics, for the alloys superhighly resistant to heat. Two of them are confirmed to be superior to the others, and selected as the alloys to be developed. This project has also established the single-crystal casting techniques, which allow crystal orientation almost completely. Various types of heat-resistant/high-rigidity and light/high-rigidity alloys are designed, produced on a trial basis, and evaluated for their characteristics. As a result, one alloy type is selected for each category. The other techniques developed by this project include those for adjusting powders for light/high-rigidity alloys whose average grain sizes are controlled and impurity contents are reduced. Bright prospects have been obtained for the techniques for superplastically forging the disk shapes. These efforts have almost achieved the development objectives of the first-phase R and D project.

    The paper established the basic evaluation method of composite particles manifesting functions which the existing mono-componet particles do not have and aimed at the international standardization of the measuring method of them. To be concrete, the development was studied of methods to evaluate the mechanical bonding state of different composition in composite particles, the chemical bonding state of different composition and the electromagnetic state of the surface of composite particles. As a result, in the evaluation method of the mechanical bonding state of different composition in composite particles, methods to evaluate the bonding state and the large composite bonding state of the coated particle layer were developed to clarify the details to be standardized for each method. In the evaluation method of the chemical bonding state of different composition in composite particles, the electronic energy loss spectroscopy was an effective method to evaluate the chemical bonding state in composite particles of oxide ceramics. Further, in the evaluation method of the electromagnetic field of the surface of composite particles, standard experimental procedures for observing the electromagnetic field by interference of electronic waves were proposed, and the evaluation of the electromagnetic field state of composite particles used ranging from low temperature to high temperature was made possible. 41 refs., 85 figs., 14 tabs.

    Efforts were made to develop methods for evaluating the characteristics of metallic materials experiencing high-speed deformation or impact deformation. The research was conducted by the research WG (working group) consisting of some participants of an international conference convened this fiscal year. The research result revealed that studies in Japan lopsidedly dealt with metallic materials at strain velocity of 10{sup 4}/second or less, such as steel, while many studies overseas dealt with materials other than metals at strain velocity over 10{sup 4}/second. The test and evaluation WG conducted high-speed tension tests for T6-treated aluminum alloys using the split Hopkinson bar method, hydraulic servo method, one bar method, and the sensing-plate method for measuring force, and the results were compared. It was then found that the one bar method produced disturbance more remarkably than the others and that the loading block structure and load rise time influenced the emergence of the peak load. The emergence of a peak load in the Hopkinson bar method or the one bar method had been predicted on the basis of the research conducted by the analysis group. (NEDO)

    The achievements during fiscal 1993 of research and development on a method to evaluate warm heat comfort by living scenes of workers by using a human body thermal model included completion of a human thermal model introduced with physiological knowledge such as artery-vein anastomosed (AVA) blood vessels and two-system blood circulation net. The effectiveness of the model was experimented and verified. It was made possible to estimate the reversal phenomenon occurring in hot heat environment, in which skin temperatures at peripheral body parts rise higher than those in the body trunk part, and skin temperature distribution. In the correlation study to estimate statistically the sense volume from skin temperatures, it was possible to estimate significantly different sense volumes from face skin temperatures, but the estimation accuracy was low because of such factors as difference in individuals. What is important in enhancing the accuracy is to identify ecological reactions of human being caused from change in the sense volume, select effective parameters, and study the mechanisms. In order to develop stress relaxing scents, discussions were given on degree of subjectivity stress by question papers and cortisol concentration in saliva as the parameters.

    With an objective of evaluating the contribution to the global environment of utilization of photovoltaic power generation, discussions were given on evaluation of photovoltaic system life cycle, evaluation of contribution to environment, and total evaluation. This paper summarizes the achievements in fiscal 1999. In evaluating the PV system life cycle, the roof-integrated modules using the thin film CdTe cells were selected as the evaluation object to estimate the energy payback time (EPT) and the CO2 emission unit consumption rate. In case of annual production of 10 MW, the EPT is 1.8 years and the CO2 emission unit consumption rate is 13 (g-C/kWh), which were found largely reducible by expanding the annual production size. For the environmental contribution evaluation which focuses on CO2 emission suppression effect as the discussion object, discussions are being given on the introduction scenario needed for the analysis. In the total evaluation, the direct employment effect assumed in Japan was discussed on production, distribution sales, installation, maintenance control and dismantling of photovoltaic generation system for residential use. The discussion showed the effect of about 7 persons per year per MW in production size of 100 MW. (NEDO)

    Research, development and evaluation were performed with an objective of establishing the basic technology related to three-dimensional circuit elements that integrate functions at ultra-high density. For the basic technology of lamination, the SOI technology suitable for the three-dimensional circuit elements was developed, and it has become possible to manufacture high-quality multi-layered crystalline structure by means of annealing that uses laser and electron beam. In addition, a lateral epitaxial technology for solid phase was developed, and the base to be applied to the three-dimensional circuit elements was established. Furthermore, the technology to put thin film circuits together would be useful for high-density integration in the future. The three-dimensional circuit makes parallel processing in each segment possible, whereas a possibility was shown that the processing can be performed at much higher speed than before. Actually a prototype three-dimensional circuit equipped with functions for parallel processing and judgment processing was fabricated. The image pre-processing which has been impossible on the real time basis in the conventional two-dimensional integrated circuit was realized in a speed as fast as milli-second order. These achievements lead to a belief that the targets for the present research and development have been achieved. (NEDO)

The R and D themes are selected to develop alloys superhighly resistant to heat, heat-resistant/high-rigidity and light/high-rigidity by controlling their crystals. Development of the basic techniques for these materials is of high significance, and highly rated. The efforts in the first-phase R and D project are aimed at designs of a total of 12 types of single-crystal alloys by the computer-aided alloy designing techniques, production of these alloys on a trial basis, and evaluation of their characteristics, for the alloys superhighly resistant to heat. Two of them are confirmed to be superior to the others, and selected as the alloys to be developed. This project has also established the single-crystal casting techniques, which allow crystal orientation almost completely. Various types of heat-resistant/high-rigidity and light/high-rigidity alloys are designed, produced on a trial basis, and evaluated for their characteristics. As a result, one alloy type is selected for each category. The other techniques developed by this project include those for adjusting powders for light/high-rigidity alloys whose average grain sizes are controlled and impurity contents are reduced.

    For the realization of urban society respecting enhanced energy efficiency and environmental protection, cities and surrounding industrial facilities are investigated for the development of element technologies involving energy recovery, conversion, transportation, storage, delivery, utilization, etc., and for the compounding of urban energy systems. In the study of the effect of introduction, assumption is made of delivery of heat to an urban heat accumulation district from a plant equivalent to a district air-conditioning system which is covered by the existing technologies. Also assumed are the delivery of exhaust heat to the said plant utilizing eco-energy element technologies and the replacement of existing technologies by eco-energy element technologies. Comparison is established in terms of energy efficiency, environmental protection, and economy, and then it is found that the eco-energy element technologies for the utilization of exhaust heat are in all cases superior to the conventional technologies as far as energy efficiency and environmental protection are concerned. It is found, however, that they are inferior from the economic viewpoint. The energy efficiency technology in heat transportation is superior to the existing technology in energy efficiency and environmental protection but roughly equal to the existing ones in economy.

    A proposal was given on a new processing process to use Ni-group super alloy, and elucidation was given on super plasticity phenomenon by using non-destructive tests. The Ni-group super heat-resistant alloy Mod. IN-100 subjected to different preforms by means of extrusion was given a super plasticity test at 1,050 degrees C to derive total elongation and 'm' value. As a result, it was disclosed that a material annealed for one hour at 1,070 degrees C after extrusion of 70% at 1,100 degrees C possesses the maximum 'm' value in the vicinity of 2.0 times 10{sup -2}s{sup -1}. The largest key to the new processing method is to improve the nature of the material, in which the plasticity manifestation velocity is accelerated by ten times to the order of 10{sup -2}s{sup -1} as described above. In addition, forging of IN-100 was made possible by using the ordinary forging equipment with the use of two-fold measures. The measures consist of maintaining temperature of IN-100 during casting by heating the die material to about 600 degrees C, rather than keeping it at a constant temperature, and then packing IN-100 in S35C steel material to accommodate the temperature decrease during casting inside the S35C pack. Thus, a processing method was made practical, eliminating need of the forging process to compress and solidify powder itself, that is the extrusion process. (NEDO)

    This paper describes the correlation and evaluation technology, extracted from the achievements in the development of a technology to apply human senses to measurements in fiscal 1992. In evaluating the warm heat comfort by living scenes of workers according to the human body thermal model, the research environment was improved by expanding the systems to measure physiological volume and the warm heat environment. Findings were acquired on the relationship between body fat rate and skin temperature, and actions of artery-vein anastomosed (AVA) blood vessels. These findings were incorporated into the research to elevate the levels of applicability of the human body thermal model. In estimating the sense volume by using skin temperatures, physiological volume being the factor of variation in face skin temperatures was elucidated, and a system to measure these variations was structured. In order to acquire the physiological volume being the factor of variation in face skin temperatures, brain wave topography measurement and {alpha} frequency fluctuation and arousal evaluation and measurement were experimented, where the effectiveness thereof was verified. Analysis was also made on blood flow rate and perspiration volume related to skin temperature variation mechanism, which has provided a number of fundamental data.

    Developments were performed during fiscal 1993 on a system to investigate correlation among external stimulating environment, physiological effects and sense volume based on a physiological reaction model. The development works included improvement of the model, discussions on a method to estimate parameters inside living organisms, and a method to collect subjectivity volume data. Prototypes thereof were fabricated, evaluated, and experimented, where nearly complete achievement of the targeted functions was verified. In developing a technology to evaluate quantitatively the comfort of composite environments composed mainly of warm heat environment, discussions were given on an integration evaluating expression in order not to make handling the environmental physical volume too complex. The expression models the evaluation of governing sense volume in individual environments of warm heat, light beam, and sound, and calculates the composite environment evaluation indexes by using the evaluation indexes obtained from the modeling as the descriptive variables. In developing the space-type human interface adapted to human senses, a computer system to realize the interface and the platform for function mounting were developed. The development items were broken down respectively on the basic technologies for functional aspect and surveillance and control function mounting, and the software systems. The human comfort meter achieved the basic design target. (NEDO)

    By research groups having been sent, the integrated evaluation was made of the projects on the research cooperation with Indonesia in the development of environmental measurement use laser radar and the research cooperation with China in the mining waste water treatment technology using biology. As to the research cooperation with Indonesia, the purpose/target proposed were almost achieved, and all were favorably carried out. Especially, after finishing the project, the design/manufacture of an on-vehicle type Mie-scattering laser radar were made using the acquired laser technology. And, it was reported that an observation study of the state of air pollution in Bandung city was made using the laser radar. It can be said that generally the research cooperation with China was smoothly proceeded with. However, the Wushan mine is small in scale of management, and therefore, there might have been some points to be reviewed in selection of the mine for research. The pilot plant installed at the Wushan mine is not now operated. If the mine has strong management force, the effective use of the pilot plant after finishing the project might have been studied.

    Weatherability tests have been performed on devices used in the residential photovoltaic power generation system by means of exposure, with the objectives to analyze and evaluate the safety and reliability due to aging of the devices used in the residential photovoltaic power generation system. This paper summarizes the achievements in fiscal 1995. In the outdoor exposure test on solar cell modules, multi-crystalline silicon solar cell modules were selected as the test specimens, and thermo-couples were embedded in the modules to measure the temperatures. Also for the purpose of comparison, storage test specimens were stored in a constant temperature and humidity chamber. The exposure tests were carried out in three locations of the city of Choshi in Chiba Prefecture, the Miyako Island test site in Okinawa Prefecture, and the Miyako Island seashore. In the measurement and evaluation, appearance observation and measurements of output characteristics and insulation resistance were executed in summer and winter. No noticeable changes were observed in the measurements after lapse of four months and six months. In the outdoor exposure tests of metal test pieces, aluminum alloys were tested for corrosion caused by contact with different kinds of metals. Although the test period was short in the current fiscal year, difference in corrosion degrees in the aluminum alloys was found already in three months. (NEDO)

This paper summarizes the achievements in fiscal 1996. In the outdoor exposure tests on solar cell modules, results of the tests were derived for up to 18 months after the start of the exposure at Choshi City, Miyako Island and the Miyako Island seashore. In the appearance observation, some white rust has appeared in the contact section of the aluminum frames of the solar cell modules and fixing screws, which have been exposed at Miyako Island and the Miyako Island seashore, but no changes that may give influence on the performance of the solar cells have been observed. The results showed performance similar to or slightly inferior to that before the exposure as a whole. The insulation resistances were all found good. According to the result of the outdoor exposure test of metal test pieces, noticeable difference in the corrosion degrees was recognized in the contact corrosion section of the aluminum alloys exposed in three areas having different meteorological and environmental factors. Electroplated zinc was found to have severer pitting corrosion in the contact sections than treatment-free zinc. (NEDO)

This paper summarizes the achievements in fiscal 1997. In the outdoor exposure tests on multi-crystalline silicon solar cell modules at Choshi City, Miyako Island and the Miyako Island seashore, the output characteristics after the exposure tests showed a result that the insolation intensity and the change in the short circuit current are approximately proportional, and the temperature in the module and the change in the open voltage are inversely proportional. The module characteristics retention rate showed no change in the 29-month exposure at all of the three exposure locations. The insulation resistance in the exposure test specimens have been good at 2,000 M{omega} or more in all the locations until 18 months have elapsed. However, the test specimens in Miyako Island and the Miyako Island seashore showed 99 M{omega} after 23 months, and 129 to 1,774 M{omega} after 29 months. According to the outdoor exposure tests of metal test pieces, noticeable difference was found in corrosion due to difference in the environment by each exposure location, whose order of the corrosion degree was the Miyako Island seashore > Miyako Island > Choshi City.

    Values given to global environment and economy by utilization of photovoltaic power generation are evaluated, and quantified to make clear the significance of the utilization thereof. Specifically, trial calculations were performed on LCA and damaging characteristics of photovoltaic systems, and reducible amount of carbon dioxide emission. Taking up thin film CdTe cells as the object, estimation was made on the energy payback time (EPT) and CO2 emission amount. The production scale ranges over 10 MW/ 30 MW/ 100 MW annually, the useful life is 20 years, and the unit requirement for CO2 emission originated from the charged electric power is 114 g-C/kWh. The EPT was 1.74 in the annual production of 10 MWp, 1.08 in 100 MWp, the unit requirement for CO2 emission was 14.0 in the annual production of 10 MWp, and 8.9 in 100 MWp. This is one of severals of that in the existing power supply source. For heavy metals, particularly Pb, the trial calculation resulted in 0.15 g/Wp in the crystalline type, and 0.1 g/Wp in the amorphous type. The problem therewith is separation and recovery. The reducible amount of carbon dioxide, or in other words, the amount of power that can be generated latently is 37,235 GWh/year, or 3.10 million tons when converted into carbon dioxide. (NEDO)

According to the data analysis result for fiscals 1995 through 1997, it was shown that, although the photovoltaic power generation system for residential use does not contribute much to load leveling in a house, it contributes to load leveling in the distribution line on the whole or a case as large as a grid. In addition, according to the survey on users who have installed the photovoltaic power generation system, it was indicated that the consciousness of electric power and energy conservation has heightened. The capacity of a photovoltaic power generation system for residential use is 3 kW for a standard type of home, which can take care of more than 60% of the house load. It was concluded that, if a storage battery of small capacity is accommodated, the system is effective for reduction of momentary peak load, enhancement of the power quality, and supply of power at a disaster.

    For the purpose of evaluating the basic characteristics of high-temperature superconducting magnetic bearings (SBM), a system model is designed, experimentally manufactured and tested, which is embodied in the design/evaluation of a large-scale system, with an investigation carried out for the introduction of the system into an electrical power system. In this framework, an examination and research were conducted for the system design technology on which each component technology in the system structure can be applied consistently in the system. In the comparative assessment of various flywheel power storage systems, the specifications and achievements were compared in the component elements of the flywheel systems developed in Europe, America and Japan through the literature studies and the field survey, with examination performed towards the future development. As a result, it was found that, in America, bearings were all SMB's without control. Boeing's objective for the development is 10kWh or so in view of convenience for transportation and is prone to arrange it in numbers. Further, investigations were made in literature and documents on the domestic and international trend of development of high-temperature superconducting flywheel systems, elucidating the details of the development.

    As the first step for the introduction of wind power systems and photovoltaic power systems into developing countries in Southeast Asia etc. and for their diffusion in them for the exploitation of natural energy, a numerical weather model useable in Southeast Asia is developed to make up for the insufficiency of weather data in the region. A technique is developed, to explain which the case of Myanmar is cited, for estimating with accuracy such natural conditions as wind direction, wind velocity, and solar radiation in the past one-year period for the assessment of power to be generated using wind turbines and solar panels. The results of the observation of wind conditions indicate that wind directions are mainly northerly or westerly and that wind speeds are as week as 1-3m/s on the average. As for total solar radiation per diem in December through March, it is found that there is 17-23MJ/m{sup 2}/day, which is twice the level to be measured in Tokyo. A comparison is made between the weather observation results and a model calculation, and it is found that the latter sufficiently reproduces the actual weather conditions. Based on the values of wind conditions and solar radiation estimated in Myanmar, the amount of power to be obtained from an assumed arrangement of wind power systems and solar panels is assessed.

    Based on the proposed cycle of each contractor, conceptual design of 500 MW class hydrogen combustion turbine power generation plant has been completed through its economic examination. The optimum system has been evaluated on the basis of the conceptual design. For the conceptual design of power generation plant, the gross power generation efficiencies based on HHV of topping regenerating cycle and new Rankine cycle proved to be 61.8% and 61.7%, respectively, which exceed the target efficiency 60%. Economic consideration proved that the construction cost of each cycle will be as the same as that of the current combined cycle power generation plant. The development problem, development step and development cost have become clear. Examination on the reliability proved that the operation reliability of each cycle will be as the same as that of the current combined cycle power generation plant. Examination on the plant layout proved that the conservation of space for each system will be smaller than that of current combined cycle power generation plant. Environmental examination confirmed that each system is very clean power generation system. For the evaluation proposed by each company, the total points of each system became in the order, topping regeneration cycle, new Rankine cycle, and Rankine cycle with reheat and recuperation. 112 figs., 44 tabs.

    For the purpose of promoting photovoltaic power generation, analysis and evaluation were conducted on the data of the project of the field test in public facilities for example. This paper describes the fiscal 2000 results. The equivalent array operation time was 2.98 h/day and, by multiplying it by the output of the standard test condition, a generated output was obtained. The system generating efficiency was 0.102 while the inverter energy efficiency was 0.917 on the average. The average array performance ratio was 0.778 and the system performance ratio was 0.714. The analysis on cost effectiveness of the installed systems has an important bearing upon the future introduction, promotion and development. The power generating cost (the annual cost was calculated as the sum of the capital cost, the direct cost, and the administrative expenses) decreased as the installation year progressed, with the average at the sites installed in fiscal 1997 at 93 yen/kWh. The system cost (calculated by dividing the construction cost by the array capacity) also decreased as the installation year became more recent. The annual maintenance cost showed a wide range from 500 yen to 30,000 yen/kW. Answers from the sites that the systems were running smoothly were 38 to 45%, while those that trouble occurrence was frequent were 2.4% on the generating systems and 12.9% on the measuring systems.

    Based on the Japan-U.S. agreement on promotion of geothermal energy applications, the R and D cooperation specialist panel was held in America on March 12-20, 1981 to exchange the current R and D information on geothermal resources. It was clarified through the meeting in Department of Energy (DOE) that the U.S. budget was reduced by the Reagan Administration largely, resulting in delays in development of geothermal energy and construction of geothermal power plants. The following themes were discussed: Japanese and American geothermal development programs, DOE's industrialization activity, hot dry rock program, geoscience program, and geothermal prospecting technology program. It was clarified through the meeting in U.S. Geological Survey (USGS) that since the governmental resource assessment is made by USGS, however, wide data collection is made by other organizations generally, acquisition of data required for the assessment is difficult. Study on MOU is necessary together with fund allocation. Field survey was also made in Raft River, Cove Fort and Roosevelt. (NEDO)

    The paper described the results of the FY 1998 WE-NET project survey. WE-NET is composed of various element technologies such as hydrogen production, hydrogen transportation, storage technology, low-temperature materials, hydrogen utilization, and hydrogen combustion turbine technology. Therefore, considering the effectiveness as a total system, it is extremely important to traversally evaluate the situation of the R and D of each technology and developmental achievements and to work out developmental plans with integration, considering the effectiveness as a total system. From viewpoints of making effective promotion of the project and attempting optimization as a total system, it is necessary to make organic/comprehensive connection and adjustment among individual subtasks all the time. In this survey/research, in the case of proceeding with the above-mentioned studies, a committee having knowledgeable persons and learned persons as members was established. There, an investigational study was conducted over the whole WE-NET structural technology, and at the same time the following were attempted: the constant/mobile comprehensive adjustment of the whole project, evaluation of the developmental results, and optimization of the developmental plans. The results obtained in 6 years of Period I were evaluated traversally and comprehensively, and how to proceed with the development in Period II was proposed, which showed the developmental continuity.

    Tests and researches have been performed with the objectives to establish an evaluation technology for load leveling effect by using a small photovoltaic power generation system for residential use, to clarify the effectiveness of the system as a discrete power supply source through demonstration operation, and furthermore to achieve optimization of designs of the small photovoltaic power generation system for residential use. This paper summarizes the achievements in fiscal 1996. The current fiscal year has performed collection of data of the demonstration operation, checked the consistency in photovoltaic power generation characteristics, and housing and distribution line load characteristics, and the results were mounted on the database. The demonstration operation data were used to analyze and evaluate the facility utilization rate in the photovoltaic power generation, photovoltaic power generation dependence of the house load, load rate, and peak load reduction rate. As a result, it was found that not much of the peak load reduction effect by the photovoltaic power generation was recognized because the house load is related mainly on lighting load. However, as seen from the distribution line load, the peak load reduction was recognized when the house load and the commercial and industrial load are mixed, whereas it was revealed that the reduction effect is worth evaluation.

    The studies have the objective of searching and evaluating biomass as energy resources and in this report, the current situation and the issues concerning development of cultivation of jojoba which has been an unused oily plant growing in arid and semi-arid areas in the southwestern USA. Its summary is as follows: (1) Jojoba is cultivated experimentally over about 20,000ha in the tropical and semitropical arid and semiarid regions at the almost same latitudes of the areas where it grows wild, (2) With regard to the areas qualified for development in the Chaco region of the western Paraguay, the La Rioja Province in the northwestern Argentina and the Eastern Province in the eastern Kenya, ample production can be expected judging from their natural environmental conditions and the growing characteristics of jojoba. (3) Jojoba is a dioecious plant and it takes 4-5 years from seeding to flowering. During this period, its sex difference cannot be identified, but a conclusion was obtained that the sex difference might possibly be identified by the isozyme method at its stage of young seedlings. (4) When cultivation techniques are firmly established and its price goes down to about 2 dollars/kg, jojoba becomes promising as substitute for sperm whale oil. 20 refs., 8 figs., 18 tabs.

    Underground air tunnel is provided for cooling an experimentally built small house and the cooling performance is examined at Kitami Institute of Technology, Hokkaido. The house is provided with 120mm-thick layers of insulating material under the floor and inside the side walls and partitioning walls. The windows are equipped with blinds, with reed screens positioned outside to cover the windows. The air tunnel is a hard vinyl chloride tube, 200mm in internal diameter. It is buried 4.5m deep in the ground, and extends as long as 27m. A filter-provided 72W blower installed at the tunnel outlet is driven to force air through. As for the natural soil temperature in summer, it is found variable between 7.2 and 8.5degC. As the result of the experiment, it is found that thanks to the underground tunnel the room temperature is kept below 27degC even when the maximum temperature in the daytime is 30degC or higher provided the air flow is appropriately regulated. In this experiment, the maximum rate of instantaneously removed heat is approximately 2.5 times higher than the values in other previously reported experiments. The daily coefficient of performance is 6.5-11.1, again higher than the previously reported values. Different from application in warm regions, the effect of rise in the surrounding soil temperature on the cooling performance is not so conspicuous. 3 refs., 12 figs., 1 tab.

    For standardization under information security evaluation criteria, an evaluating technique CEM (Common Methodology for Information Technology Security Evaluation) was constructed as ISI/IEC15408. The method, however, is abstract in content and the evaluation work thereunder requires much time and accompanies economic difficulties. In dealing with the situation, investigations were conducted into security evaluation related techniques and manufacturing/quality control techniques in use at information processing product developing sites, and a CEM technique is materialized. Using the proposed technique, developers themselves can evaluate security in the development process and workloads imposed on evaluating organizations may be reduced because evidential items necessary for 3rd party evaluation may be gathered. Since the developed technique is verified by an official evaluating organization, it is expected to be an effective techniques not contradicting existing operating techniques. It may be also said that this technique is a method whereby developers will collect evidential items necessary for their development efforts. The result will be presented in the form of a proposal for an evaluating techniques standard for ISO/IEC JTC1 SC27. (NEDO)

    Research and development has been performed with the objectives to establish an evaluation technology for load leveling effect by using a small photovoltaic power generation system for residential use, to clarify the effectiveness of the system as a discrete power supply source through demonstration operation, and furthermore to achieve optimization of the small photovoltaic power generation system for residential use. This paper describes the actual state survey data related to grid connection systems for the small photovoltaic power generation system for residential use. The survey has been performed mainly on the system for individuals' use inside and outside Japan with regard to the small grid connection systems of 1-10 kW scale. The number of survey has reached 216 cases for 46 prefectures in Japan (1,004.02 kW in total), and 47 cases for 13 other countries (205.60 kW in total), or 263 cases in grand total (1,209.63 kW). These 263 cases were tabulated with items of owners (or the facility names and installation locations) as seen by territories (prefectures or countries), facility operators (or executing organizations), connection modes, and power generation scales. These data will serve for discussions on the load leveling effect and the optimized system forms. (NEDO)

    The field tests on photovoltaic power generation systems for public facilities have begun in fiscal 1992 by NEDO. The systems including those under construction are installed in 116 sites. Analyses were given on 75 sites which have been operated up to fiscal 1996. Analyses of the operation characteristics were performed by using performance parameters derived by developing the basic expressions into each configuration element. For the insolation on slanted surface, the range from 3.0 to 4.5 kWh/m{sup 2}/D accounts for 65% of the total insolation. For the equivalent array operation time, the range from 2.5 to 4.0 h/D accounted for 81%. For the equivalent system operation time, the range from 9.0 to 12.0 h/D accounted for 85%. The range for inverter active efficiency from 0.84 to 0.96 accounted for 79%. The inverter load rate was accounted for 88% by 0.20 to 0.35. The output coefficient was accounted for 82% by 0.7 to 1.0 in the array, and 87% by 0.6 to 0.9 in the system. The power generation cost has decreased to 200 yen per kwh in fiscal 1995 from 340 yen per kwh in fiscal 1992, largely contributed by reduced installation cost. (NEDO)

    The paper proposed the international standardization for the use of next generation image media by evaluating health effects of the use of next generation image media such as head mounted display and 3D monitor. A method to comprehensively evaluate health effects was studied with the design friendly to humans and standardization on safety as final targets. Themes were divided into the autonomous nervous system and the measuring system. The development was carried out of a method to evaluate the autonomous nervous function by the dynamic state of blood circulation and pupillary reflex as well as the development of portable sphygmomanometer and pupillometer. Using these developmental instruments and conventional instruments, measurement was made of blood pressure, cardiac output, respiration, pupil size, eyeball movement and focus accommodation. A possibility was suggested of obtaining the uniform elucidation also in case analytical changes of individual parameters cannot be extracted or consistency cannot be seen in the course of changes. The paper determined basic standards for the experimental use stereoscopic image, made measuring use 3D images, and collected realtime data by the overall simultaneous measuring system constructed. 109 refs., 166 figs., 18 tabs.

    To select projects of the New Sunshine Program which is the locomotive for Japan`s research and development of energy and environmental technologies and to map out the Program`s long-term strategy, it is required to develop an effective methodology of assessing research and development themes. It is also necessary to establish the pre-assessment system which makes the assessment process more logical and which will enable the priority setting among different themes on the basis of objective and quantitative analysis. Additionally, transparency should be ensured for such a pre-assessment process through disclosure to the public and other means. The present survey aims to concretize the pre-assessment system by studying the system and techniques of an assessment system which is applicable to the research and development themes of the New Sunshine Program and is objective, quantitative and logical and which can ensure transparency and by receiving suggestions on the pre-assessment of Japan`s research and development of energies and environmental technologies through research on overseas trends of government-led research and development. 3 refs., 7 figs., 26 tabs.

    The paper studied the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. Chemical composition and coating thickness (g/m{sup 2}) of 14 kinds of specimens including alloy coatings and organic coating with zinc and aluminum as base were analyzed by the above-mentioned methods to examine the relation between the both. As the chemical analysis method, used was inductively coupled plasma atomic emission spectrometry. To study the relation between the methods, it was found to be necessary to recognize morphology at the boundary between the coating and base steel using, for example, scanning electron microscope (SEM) and electro-probe micro-analysis (EPMA). To measure traceability of the analysis method, with the chemical analysis method as a judgement method, it is necessary to make reference materials by coating materials, to use the calibration graph confirmed by the materials and to adopt the glow discharge optical emission spectrometry. On the basis of such way of thinking, drafts were worked out for the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. 7 refs., 117 figs., 33 tabs.

This paper summarizes the achievements in fiscal 1995. With the demonstration operation in the current fiscal year, through-the-year data have been accumulated for the first time since the start of the demonstration operation, and were mounted on the load leveling database. As a result of analyzing the demonstration operation data, the following points were revealed: regarding the housing load, the lighting load is the main factor both in summer and winter; the effect of reducing the peak load by photovoltaic power generation is recognized at about 60% as maximum, but the substantial effect has large variation, hence stochastic; and the reverse current becomes the main factor during daytime, not necessarily leading to improvement of the housing load characteristics in the aspect of load rate. According to the surveys on the energy demand trends up to the year 2030, the power supply configuration, and introduction cost, it was revealed that the photovoltaic power generation can be sufficiently expected as a power supply to handle the peak load.

    For the purpose of evaluating the basic characteristics of high-temperature superconducting magnetic bearings (SBM), a system model is designed, experimentally manufactured and tested, which is embodied in the design/evaluation of a large-scale system, with an investigation carried out for the introduction of the system into an electrical power system. In this framework, an examination and research were conducted for the system design technology on which each component technology in the system structure can be applied consistently in the system. In the comparative assessment of various flywheel power storage systems, the specifications and achievements were compared in the component elements of the flywheel systems developed in Europe, America and Japan through the literature studies and the field survey, with examination performed towards the future development. As a result, it was found that, in America, bearings were all SMB's without control. Boeing's objective for the development is 10kWh or so in view of convenience for transportation and is prone to arrange it in numbers. Further, investigations were made in literature and documents on the domestic and international trend of development of high-temperature superconducting flywheel systems, elucidating the details of the development.

    Japanese paint users demand products of higher-quality than users in the U.S. and Europe, and therefore, paint makeres in Japan are making strenuous efforts to improve the product quality in terms of homogeneity, appearence and durability of the surface of paint films. However, the evaluation of paint surfaces is conducted by the qualitative sensory evaluation, resulting in obtaining no appropriate evaluation. Accordingly, the following were developed as new evaluation methods which give rational and economical indicators, contribute to shortening of the period for development of new products, and aim at the international standardization: 1) quantitative evaluation of the paint drying process; 2) image analysis of the degraded part of paint films; 3) surface analysis of paint films. In 1), a kinetic friction measuring quantitative evaluation of the surface of paint films was developed. In 2), the development of an exclusive program by the image analysis made the quantitative evaluation with high accuracy/reliability possible. In 3), an evaluation method was developed in which differences among the specimens can be detected by the chemiluminescent measurement in an extremely early stage of exposure when the gloss change just begins. As to the chalking, a new evaluation was developed in which the degree of chalking can quantitatively be evaluated by attaching a special adhesion tape to the degraded part of paint films and by the optical measurement of the degree of transparency. 101 refs., 341 figs., 118 tabs.

    This paper is a survey report for fiscal 1999 related to investigations on evaluation on impact (influential effect) of research and development investments, and on optimal resource distribution. First, a quantification analysis was performed on the impact imposed by the New Sunshine Project having been executed in the past. The analysis used as the base the regressive analysis between the project techno-stock (an index of the project budget amount depleted by a certain obsoletion rate after having been substantiated and aggregated) and the number of theses. In a case where time-series data can be obtained on the quantity of practical application, the regressive analysis was also performed between the number of theses and the quantity of practical application. A large number of projects are stimulating research and development activities of the subject themes of all about Japan. Some are imposing great influential effect on the practical application. In addition, it was found that emphasized and concentrated investment cases in the initial stage of a project have high influential effect. As a budget distribution pattern, the concentrated and emphasized investments in the initial stage of a project are more effective than investing dispersedly over an extended period of time. Suggestions were acquired on the future budget distribution. (NEDO)

    Modern apparel industries are required to supply many kinds of products corresponding to various needs of consumers. Among consumers' needs, comfortableness to wear such as size-fitness is primarily important. To facilitate apparel industries, it is expected to develop a new technology of pattern designing of comfortable garment and measuring garment pressure distribution. Our research is aimed at developing technology that uses computer simulation to predict and evaluate wear comfort, including size suitability, without the need to actually sew up a garment. First, we developed a basic system to predict wearing silhouette, garment pressure, and ease looseness of the garment. Using this system, we carried on the following study. The 3-dimensional distributions of the garment pressure and ease looseness were reversely mapped on the paper pattern in order to indicate the preferable modification. The system was extended for several poses, e.g. twist, bend. From various parameters, we examined the factors of garment pressure and ease looseness. In addition, we selected the parameters for the size-fit indicators and investigated size-fit evaluation indicators. (author)

    The configuration of water recycling systems with membrane filters was studied to purify waste water discharged from human beings, animals and plants which is a key subsystem for closed ecological life support systems (CELSS) essential to long-term manned space activity. The filter performance test apparatus with three kinds of filters such as pre-filter, reverse osmosis membrane filter and ultra membrane filter was fabricated to conduct long-term cycling high-concentration tests using artificial urine as original waste water. As a result, since every membrane filter offered their nominal performance incompletely in high-concentration tests, it was necessary to add an NaCl removing apparatus to the system as primary treated water should be used for vegetation. It was also required to test the membrane performance preliminarily because the performance such as membrane life was different between various waste waters. 7 refs., 32 figs., 9 tabs.

    A geothermal reservoir assessment manual was prepared for the promotion of the development of geothermal power generation, based on the results of the 'geothermal reservoir assessment technique development project' implemented during the fiscal 1984-1992 period and on the results of surveys conducted in Japan and abroad. Of the geothermal systems generally classified into the steam dominant type and the hot water dominant type, encounters with the steam dominant type are but seldom reported. This manual therefore covers the hot water dominant type only. In addition to the explanation of the basic concept and the outline of geothermal reservoirs, the manual carries data necessary for reservoir assessment; geological and geophysical data analyses; geochemistry in reservoir assessment; data of underground logging and of fuming; conceptual models; simulators and models for reservoir simulation; natural-state simulation, history-matching simulation, and reservoir behavior predicting simulation; case history (modeling of a geothermal reservoir prior to exploitation), references, and so forth.

    This paper explains the concept, history, and analytic methods of life cycle assessment (LCA), showing its application to beer bottles and cement factories as specific examples. The LCA is a method to calculate substances and energies put into the whole process of production of a product from raw material mining to product wasting and environmental loads emitted therefrom. It also evaluates the result collectively and quantitatively. A first case of the research is reportedly the one performed at Coca-Cola Co., Ltd. in 1969. Full-scale researches have gone forward in European countries in the recent several years, and are progressing to international networks. The analytic methods can be divided largely into an accumulation method to analyze data in each process and add them up, and a method to use an industrial association table. The former method is the most generally used method currently in overseas countries if referred to the LCA. Because the LCA can cause the analytic result and evaluation to vary depending on the purpose, it is important to define the goal, and set the scope. The LCA must develop in the future although it has a number of problems. 10 refs., 5 figs., 2 tabs.

    As a part of the evaluation of landscape of civil engineering structures, a method was studied for quantitative evaluation of surface color and color hue of the exposed concrete. The surface colors of concrete structures constructed at more than one sites were measured using a colorimeter and were statistically processed. The colorimeter can measure colors by irradiating the standard light onto the surface of the object and dividing the reflection light into ingredients, lightness L and color phase a and b in the CIELAB equal color space. The L/a/b measuring data were plotted which were obtained from 2010 measuring surfaces of 49 structures at 7 construction sites. As for the surface color of concrete, it was found that ingredient L measured by the colorimeter reacts on variations of color very sensitively and agrees well with the trend of evaluation by eyes. Namely, human being senses the difference of concrete color mainly from the difference in lightness and senses the difference as the color hue. Further, using the neural network, an evaluation method was established which was the same as the human sense. 1 ref., 8 figs., 3 tabs.

    Toxicity of petroleum component to aquatic organisms appears as a result of its deposition onto living organisms followed by its migration into bodies of the organisms, and emergence of toxicity from the migrated component. Effect evaluation processes standing on this viewpoint may include the exposure monitoring or migration monitoring, in which the petroleum component migrated into marine organisms is analyzed and the state of the component concentrated in these organisms is measured, or effect monitoring, in which actions of the petroleum component in the organisms are investigated. The effects of petroleum on aquatic organisms would include the following occurrence: direct fatal toxicity acting on cells and membranes, quasi-fatal toxicity causing death indirectly through feeding actions and abnormal actions, direct coating of oil on surface of organisms, which prevents movability and feeding actions of the organisms and reduces hydrophilicity of plumes and hairs, pollution of living organisms due to migration of carcinogenic aromatic compounds into bodies of the living organisms, and change in species compositions and geographic distribution of living organisms due to change in physico-chemical environment. This paper explains cases of detection and identification of organic sulfur compounds, aromatic compounds, polycyclic aromatic compounds, paraffins, olefins and heavy metals in parametric compounds of petroleum. 20 refs., 4 figs., 3 tabs.

    Human auditory sensation has both extremely excellent performance and general versatility as sound analyzer. At present, it is impossible to make equipment with the same functions as human being, and describe an auditory sensation function as acoustic sensor even by any physical analysis techniques. However, extraction of auditory sensation parameters is becoming possible by using psychoacoustics and binaural signal processing. This paper mainly explains the calculation method of sound quality evaluation parameters derived from psychoacoustic results based on a sound quality evaluation system under development by the authors. This system is based on binaural measurement by dummy head, and calculates psychoacoustic parameters such as loudness, sharpness, roughness, fluctuation strength and tonality through frequency analysis of the measured stereo signals. The system also calculates 2-D parameters such as sensory pleasantness and unbiased annoyance based on the above parameters. 12 refs., 4 figs.

    The photovoltaic/thermal hybrid panel (PV/T) is an energy converter that was designed for the composite use of electricity and heat. In this paper, the validity of PV/T designed for trial was evaluated based on an exergetic theory. As the result of an experiment, the electric exergetic value of PV/T and PV is each 65.8 kWh/m{sup 2} and 58.6 kWh/m{sup 2}. The former is higher than the latter by 11.2%. The total exergetic value of PV/T is also 1.2 and 8.2 times as high as those of a PV and solar collector (SC), respectively. The calculation result of the optimum temperature operation showed that the exergetic value of PV/T is 3.1 times as high as the electric exergetic value. Therefore, the operation must be performed with the electric and thermal exergetic values set in a ratio of 3.1 to 1. In this paper, the operating mode is handled in which importance was more attached to the electric exergy than the thermal exergy. The flow rate of a heating medium on PV/T is not thus the flow control that maximizes the PV/T exergy. In the future, studies including these points will be promoted. 7 refs., 7 figs., 3 tabs.

    This paper describes the considerations on the influence of the global warming on the environment, and the discussions on the measures against the climatic changes. With respect to the environmental effects by the global warming, the considerations were given based on the studies on the effects of mainly the Quaternary climatic changes on the surface sea water temperatures, sea level and animal flocks. If the magnitude of the climatic changes anticipated to occur during the 21st century is lower than that have taken place in the past 10,000 years during which the agricultural production has developed to a full-scale, there would be no fear of drastically changing the ecology on earth. If the estimation of future climatic and environmental changes becomes possible, then four basic positions could be selected for establishing the contermeasure plans. That is, the first is the measures to correspond to birth-rebirth transmigration; the second is the measures to carbon dioxide disposition upon concluding that the cause for the global warming is the atmospheric increase of carbon dioxide concentration, measures for conservation and international cooperation; the third is to deal with the warming environments; and the fourth is the means to reconstruct the earth. While a number of countermeasures may be prepared, Which of them should be selected will be decided by the amount of effects. 15 refs., 6 figs., 1 tab.

    For human engineering and improvement of the living environment, the evaluation technology of human behavior cognition was studied. For the future reformation and creation of economic structure, the following are required: establishment of safe and affluent communities, further improvement of the safety and harmonious balance of people, lives and society, and R & D close to people and social needs. Introduction of Product Liability law and a fail-safe concept are examples of such efforts. However, since many accidents are found in the human society, the relation between human errors and human characteristics should be studied in detail. The cognitive science of human behavior is an objective evaluation technology from the viewpoint of human being, object, environment and society. Based on these social and technological background, the feasibility of the evaluation technology is studied, and the future trend and skeleton of this project are clarified. The domestic and foreign trends of technologies concerned are thus surveyed, and the important points, features, skeleton and ripple effect of the technology are summarized. 500 refs., 70 figs., 5 tabs.

    The effect of residual stresses on brittle fracture was investigated on the basis of the Local Approach. Compressive residual stress was introduced by pre-loading and the subsequent fracture test conducted with a 780 MPa class steel. Preloading apparently increased the critical load and critical CTOD at the onset of brittle fracture initiation. The Weibull stress criterion was used to evaluate the brittle fracture resistance of the pre-loaded specimen. The critical Weibull stress is a material property independent of test conditions with and without pre-loading. Using the Weibull stress criterion, the critical CTOD of the pre-loaded specimen can be predicted from test results of the specimen without pre-loading. (author)

    This is No.91 report of National Institute for Research in Inorganic Materials, concerning cobalt oxide. For the growth of single crystal by the Czochralski method, shape of interface and contamination of impurities are affected by the convection of molten liquid in the atmosphere. Various oxides besides CoO were investigated. Solid solutions of Cr2O3 and Al2O3 into CoO were also studied. Non-linear optic and dielectric properties of single crystals, such as Ba2NaNb5O15 and LiNbO3, were examined. It was considered that the positive electron having positive electric charge can be used for the study on the negative electric charge defect in materials. However, the positive electron itself is rare, which results in the too low efficiency of measurement. Efficiency improvement of 50 times was achieved by introducing a high performance 2D position detector, which was still low efficiency of one-hundredth compared with photoelectron spectroscopy. It was found that the aggregation structure of positive ion defects in CoO is a misunderstanding of phenomenon caused by the electronic state in bulk crystals. As a result of the study on the optical properties of f-electron transition metals, transparent ceramics with addition of various rare earth ions were described. 162 refs., 106 figs., 14 tabs.

    Sinters of silicon nitrides have excellent properties as a structural material, but their technological repercussion effect is not as much as has been expected. The cause is in insufficient understanding on the mutual relationship between microstructures and mechanical properties. Therefore, methods of controlling structures were first discussed in the studies on synthesis of high-tenacity ceramics. In order to achieve high reliability in material strength, discussions were given on means to have a structure developed with high reproducibility. Development was performed on {beta} powder which shows no abnormal grain growth and is stable at elevated temperatures. Then, quantitative evaluation was made on factors to manifest a self-compounding structure with columnar particles grown in ultrafine particles. The relationship between its chemical composition, microstructure and mechanical properties was also discussed. Particle shapes of silicon carbides and their fracture tenacity values were considered theoretically by using a drawing model. To evaluate the microstructure, it is important to determine the grain boundary composition, whereas an electric field radiation type high-performance electron microscope was developed. In discussing the fracture mechanism, a model was structured for behavior of covalent binding crystals against external stress. 164 refs., 95 figs., 10 tabs.

    This paper illustrates the results of field tests conducted as a basic investigation of electroseismic phenomenon at the site of Kyushu University. The electroseismic phenomenon is a physical phenomenon in which electromagnetic response is derived by the incident elastic wave in the underground. According to Karl E. Butler, et al., mutual motion occurs between rock matrix and pore water by the propagation of P-wave in porous media. Spatial change in the water content per unit volume occurs, which is similar to the density change with the propagation of P-wave in elastic solid. Since the pore water with mobility can bring charges generated in the electrical double layer, the change in the water content agrees with the density change. Accordingly, domains of positive and negative overcharges are generated at the top of P-wave, which can be a current source. An electric field is generated between the domains. As a result of the field tests, it was confirmed that electromagnetic phenomena can be derived by the elastic waves. 2 refs., 8 figs.

    This paper describes attempts of establishing an oil recovery technology utilizing microorganisms and of aiming at improving the practicability of that technology. Fiscal 1994 has investigated effects of inorganic salts existing in reservoir beds and NaCl concentrations on proliferation of microorganisms and production of metabolites. The investigation was intended to discuss applicability of microorganisms to environments that are brought closer to actual field conditions. Furthermore, a core sweeping test using sandstone was carried out on the fiscal 1992 separated bacteria, the 4118 bacteria, that has high surfactant production capability. In addition, a sand pack was used to perform a flooding experiment under conditions of 50{degree}C and 50 KSC to evaluate functionality of microorganisms when environments in the reservoir bed are simulated with respect to pressures and temperatures. An oil recovering experiment was carried out using a sandstone with a diameter of 1.5 inches, a length of 1.0 foot and permeability of 600 md, and using Bacillus subtilis 4118 bacteria which attained the lowest interfacial tension among the bacteria examined. A recovery rate of 4.4% Sor was derived in the experiment. A recovery rate of 29.0% Sor at maximum was obtained when Bacillus licheniformis 18-2-a bacteria was supplied into a sand pack filled with silica sand. 20 figs., 7 tabs.

    Study was made on the storage method of a methane component in biogas mainly composed of CO2 and methane gases. Methane clathrate as molecular complex is one kind of clathrate compounds. Eight methane gas molecules are absorbed into 46 water molecules, or methane gas of 216 l is absorbed into water of 1 l, resulting in considerable compact methane storage. Although methane clathrate is usually stable only under a condition of low temperature and high pressure, its formation equilibrium shifts toward a low pressure/high temperature side by adding additives such as amine, ether and ketone. Acetone can shift formation pressure from 30 to 10atm at 1degC, and formation temperature from 1 to 10degC at 30atm. Although methane liquefaction is also an efficient storage method, it requires liquefaction temperature and pressure of -83degC and 45.6atm, respectively. The distance between methane molecules in clathrate lattice can be more shortened than that in high- pressure charged gas, suggesting higher storage efficiency. The study result showed that the handling of methane clathrate is possible around room temperature and pressure. 7 refs., 5 figs.

    Acid fog research was behind in comparison with acid rain research. In case of acid fog, it is because the place generating sufficiently thick fog to collect is limited, the generating place is mountainous, its survey needs a lot of works, its collector is not convenient like in acid rain, or its sampling is difficult on its automation. Since the 1980s, an extensive survey on acid fog had been carried out centering the west coast of California, USA, and low pH fog (minimum pH 2.2) was observed. In the course of these researches, string type active fogwater collectors became a major sampling method, and the simulation of acidification of fog droplet in the atmosphere was extensively conducted. In Japan, already in the 1960s, field surveys on acid fog were conducted, in 1984 acid fog survey started on Mt. Akagi under a viewpoint of ecological impact, and there was a report that low pH fog (pH 3 to 4) continued more than 10 hours. It was pointed out that there were plant damage by acid fog in several locations, especially the tree mortality mechanism in Tomakomai was clarified. 50 refs., 10 figs., 6 tabs.

Biosensor that normally transfers the amount of chemicals into electrical signal is a sensor in which living materials like enzyme, microorganism or antigen, antibody and so forth are used in the recognition part. Recently, the structure or the function of the living materials is clarified gradually with the significant progress in biofeedback, however, the synthesis of artificial material having same function as that of living materials is extremely difficult. Accordingly, it is very practical to develop high degree sensor function by using living materials with developed function in material recognition part, an important element of the sensor. In this report, solid state biosensor using electrode as a transducer is focused, and specially, recent research progress regarding the amperometric measurement which measures oxidation/reduction current is discussed. 35 refs., 8 figs., 1 tab.

    Leading research on brainware is conducted to realize the engineering information processing based on the learning, memorization, association, intuition, value judgment, and motivation which are activities of human brains. For the highly integrated information society at the 21st century, it will be essential to establish human-like information processing technology which is considered to be difficult with the conventional computers. The R and D theme for this technology will focus on the development of novel devices and systems by eliciting the principles and key roles of information processing functions of the brain and in living organisms from both viewpoints of the science and engineering and the brain information science. It is considered that important research targets are in elucidating brain functions and the modeling and developing novel devices and systems, such as brain information architecture, neural devices, neural networks, and man-machine interface. Technical trend surveys in the USA, the UK, and Germany were also conducted. 347 refs., 58 figs., 7 tabs.

    Among the EDS, H-Coal and SRC-2 lined up in the coal liquefaction project of the U.S., the SRC is aimed at producing 6,000 t/day as a module for a 30,000 t/day commercial plant. They expect Ash contents (iron, sulfur, etc.) in coal without basically using catalysts. The products are applicable to fuels for electricity and gas for the moment. In the element technology, there are some problems in manufacturing hydrogen by gasification of residuals as well as in slurry systems, reaction towers, etc.. In the 30,000 ton commercial plant, the coal-liquefied oil costs $19.89/bbl (price as of 1978) assuming coal costs $29.47; therefore, the feasibility is strong as a substitute for petroleum. Japan's share for the required funds will be 86.8 billion yen (if 250 yen per dollar). Since the kinds of coal are conceivably increased in number through the improvement of the process, the Pacific rim countries and these which lie on the Indian Ocean are assumed to be the major coal producing countries for Japan. The stability in storage of coal-liquefied oil is experimentally excellent, as is the compatibility with petroleum products for example. Great results can be expected in the technical know-how and the spread of element technology for Japan. (NEDO)

    This paper reports the activities of the environmental safety evaluation sub-committee for the coal liquefaction plant in fiscal 1992. The sub-committee, upon having received reports on the result of environmental safety evaluation tests performed in fiscals 1991 and 1992 by NEDO, deliberated and discussed carefully the contents thereof. In order to ensure labor hygiene for coal liquefaction plant workers, health influence on liquefied oil users, and social acceptability of the liquefied oil, NEDO has performed the comprehensive brown coal pilot plant operation and oil safety tests. The tests are in accordance with the labor safety and hygiene law, the chemicals examination law, and the MPD issued by OECD, and performed on each fraction produced in the pilot plant and the whole fraction mixing the former fractions, using rats, rabbits, and guinea pigs. The test items included: acute inhalation toxicity and oral repeated administration (using rats); eye stimulation, repeated coating and skin stimulation (using rabbits); photo-toxicity (using guinea pigs); mutagenicity tests (microorganisms, bacteria and chromosome anomaly); resolution tests; fish toxicity; concentration degrees; algae growth obstruction; and water flea breeding obstruction. As the result, the toxicity was found light. (NEDO)

    The multi-offset hydrophone VSP experiments were carried out using a 750m deep borehole as the oscillation receiver, which penetrates the Nojima fault, to detect water-permeable cracks and evaluate their characteristics. Soil around the borehole is of granodiorite, and fault clay is found at a depth in a range from 623 to 624m. A total of 4 dynamite tunnels were provided around the borehole as the focus. The VSP results show that the tube waves are generated at 22 depths, including the depth at which fault clay is found. However, these waves are generated at only 6 depths in an approximately 150m long fracture zone, suggesting that the cracks in the zone are not necessarily permeable. It is also found that crack angle determined by the analysis of tube waves almost coincides with that of fault clay determined by the core, BHTV and FMI, and that permeability is of the order of 100md at a depth of fault clay or shallower. 3 refs., 2 figs., 2 tabs.

    A demonstrative test was conducted to verify economical efficiency of practical scale hydroponic horticulture under structure making use of a part of the Osaki thermal power plant to be constructed. In the test, the hydroponic culture of leek and tomatoes was carried out for six years starting 1989 to study its economical efficiency. Using the M-type hydroponic culture facilities, the structures are 1200m wide, 29m long, and 21 tons in the culture liquid level in case of leek, and 350m wide, 29m long, and 10 tons in the culture liquid level in case of tomatoes. The evaluation was made estimating the crop amount of leek as about 35 tons and that of tomatoes as about 60 tons and regarding that the sales amount is equal to the crop amount. The sales amount of leek is 28 million yen, and when seeking income/expenditure from expenses, deficit of 1 million yen per 30 a cannot be avoided excluding the equipment depreciation cost. As to tomatoes, the shipment cost is approximately 14 million yen without the equipment depreciation cost, but the sales amount is approximately 13-19 million yen largely affected by the unit price. A study on the sale method is needed. 7 figs., 11 tabs.

    The authors proposed an aeration filling method as a new filling method in order to obtain uniform and high speed filling by carrying out basic experiments on powder material filling using a visual apparatus. In this study, the aeration powder filling was applied to the product compacting on the actual compacting press, and its evaluation was carried out. As a result, the following effects were confirmed. The weight scattering was reduced to about 70% in the high speed filling and about 50% in the low speed filling. The maximum density was reduced to about 30% in the high speed filling and about 25% in the low speed filling. The maximum thickness difference was reduced to 65% in the high speed filling and about 20% in the low speed filling. The aeration powder effect was stronger in the high speed filling than that in the low speed filling. The weight and size accuracy of the components were increased by the aeration powder filling. The pause and the shaking operation were discarded in the front part of the powder box, thus the filling time could be remarkable shortened. 3 refs., 6 figs.

    Concerning a high level treating method of regeneration of sewage water, there are methods of coagulation/precipitation, sand filtering and ozone treatment in addition to the conventional active sludge method. However, none of these methods are perfect from the viewpoint of virus. A film treating method to remove micro-organisms in water is twofold, i.e., microfiltration and reverse osmosis. For such filter treatments, polio virus is most suited as an experimental index for conducting an assessment of the treating ability of viruses. The reasons are as follows: 1. It is the smallest virus among the viruses which are mixed in the water systems. 2. Polio virus is always detected in the study of actual conditions of the viruses contained in the sewage waters. 3. It involves less danger in handling because there are vaccines which are made less poisonous. 4. Separation and quantification of viruses is easily conducted by means of cultured cells. 8 refs., 1 fig., 7 tabs.

    Electron paramagnetic resonance (EPR) of coals was considered by using iodine doping technique. Sub-bituminous coal (WA) and bituminous coal (UF) were used to observe EPR spectra using microwaves. With the UF coal, strength of the narrow component of the spectra was found constant regardless of amount of the doped iodine, wherein radicals without interaction with iodine were detected. Strength of the broad component increased with the iodine doping amount, where in deviation of {pi} electrons was detected, which have been generated as a result of interaction between aromatic rings and iodine in the coals. Spin concentration of the WA coal with low coalification degree is constant regardless of the iodine doping amount, and the interaction of the iodine with the aromatic rings was found small. The higher the coalification degree, the more the aromatic ring structure grows, and electron donor capability for the iodine increases. In a system with the entire spin being uniform, the spectrum height shows a saturation phenomenon against increase in microwave output. A non-uniform system, in which the oriented spin forms small groups and is in local thermal equilibrium, does not show saturation, but increases monotonously. 2 refs., 5 figs.

    The environmental safety evaluation sub-committee has held two meeting in the current fiscal year as described below. The first sub-committee meeting (August 25, 1987) was held for the agenda of the summary of future test plans, the result of overseas surveys in fiscal 1986, the results of tests in fiscal 1986, and the summary of the test plan for fiscal 1987. The major agendum of the second sub-committee meeting (February 23) was the interim reports on the overseas survey results and the safety tests in fiscal 1987. NEDO intends to ensure the labor hygiene for workers in coal liquefying plants, the effect of liquefied oil on users' health, and social acceptability of liquefied oil. Therefore, a safety test for liquefied oil in the primary hydrogenation process was performed provisionally on brown coal PP in the initial stage of operation, in addition to bituminous coal liquefied oil at the existing 1-t/d PDU. The main contents of the test performed by NEDO are based on the labor safety and hygiene law and the law related to regulation on the deliberation and manufacture of chemical materials. Different tests using guinea pigs were carried out on the total fraction mixed at the 1-t/d PDU, and each fraction of light and heavy oils, where the liquefied oil was verified to have minor degree of toxicity.

    The author expresses his opinion toward the impact to be brought about by changes in evaluation standards mainly involving the power system. The 20th century has been an age of mass production of various articles and mass consumption of various resources. It has become evident of late that flexibility, which will realize environmental impact reduction and satisfy varying needs, should be added to the evaluation standards. The new evaluation standards urge that the large-scale centralized management type system be converted into an autonomous distributed type system, and mass production into small-scale production of multiple articles. The development from centralization to decentralization, and the trend toward deregulation and the corporation's plan of dividing itself into plural in-house companies, may be evaluated against the same context. In the field of power systems, it is deemed that the diffusion of power retailing business and distributed power sources will be accelerated. When it comes to a power system constitution and operation capable of dealing with the new development, an autonomous distributed type system constitution and operation as a local energy system is supposed to be more appropriate than the conventional centralized management type.

    Elaboration of the evaluation guidelines for activities implemented jointly (AIJ) was researched to prevent the earth from warming. AIJ is the means to globally promote countermeasures against global warming cost-effectively by optimally combining every country`s technology, know-how and fund. AIJ was established in the 1st Conference of the Parties (COPI) of the United Nations Framework Convention on Climate Change in March, 1995. The pilot phase of AIJ is first carried out by voluntary workers jointly with developing countries under the agreement of the parties. The current situation of activities is reported in COPI as materials for evaluation of AIJ. To promote AIJ, elaboration of the evaluation guidelines for AIJ Japan program is also necessary for Japan. This research arranged the contents of the evaluation guidelines and the method of classifying projects for AIJ Japan program, and carried out some case studies of promising projects to reduce greenhouse gas emission for future proposal. 3 figs., 31 tabs.

    Considerations were given from a viewpoint of assessing toxicity to human bodies on methods of assessing water pollutants and organisms, and applicability of cytotoxity test using cultured cells to water quality assessment. Biological assessment systems used for water environment may use tests using multicellular organisms, cells, or organelles in cells. The organism assessment method is intended mainly for assessing ecological effects, and a suitable method must be selected upon extrapolating it to human bodies. A toxicity parameter used most frequently in a cytotoxity test is the cell revival rate, and life and death are determined from liberation of enzymes in cells, or with color rejection tests and incorporation tests. There are a number of test specimens of raw tap water and its chlorine treatment condensate that show no mutagenicity but cytotoxity. Efficiencies of removal by means of mild chlorine treatment, fast filtration, and activated carbon adsorption vary greatly with cytotoxity and mutagenicity. Introducing the cytotoxity test is expected of further contributing to improving safety in water quality. 24 refs., 1 fig., 7 tabs.

    This report describes the historical procedure of a bacterial test for a certain respective bacteria, and also describes the removal of micro-organisms by a water treatment and treatment with disinfectants. The disinfection is made mainly on basis of foreign literature. This is because there exist few literature published in Japan. In a good sense, this is because of the Japanese habit of drinking raw water which has contributed to high level of facilities and the maintenance. If seen from a different viewpoint, the prsent concern is concentrated to a contamination of the underground water by organic solvent and the counter measure against such minute quantity of organic chemicals as trihalomethane and the agricultural chemicals in the golf courses. From the consumers {prime} standpoint, these are of the level of problems that only one affected person increases per year for 100,000 inhabitants even if they continue to drink such drinking waters continuously through their life years. The reality is that it is remote from the realities in life. 37 refs., 9 tabs.

    Hydrophone VSP (vertical seismic profiling) experiment is under way as a technique for detecting subsurface water-permeable cracks by use of boreholes and for evaluating their characteristics (permeability index, crack direction, dip angle). In this report, tube waves observed by hydrophone VSP are subjected to analysis for the determination of water-permeable crack characteristics, the impact caused by errors in the value inputted for analysis is estimated, and a model calculation is performed in case there is no agreement between data from the borehole and data from VSP, all for examining the VSP records for accuracy. When an error rate of 15% is given to the tube wave/P-wave amplitude ratio, a change of 40% or lower results in the permeability index, and a change of 10deg or less in the dip angle, which means that an error in the amplitude ratio does not affect the analysis very much. Changes in the amplitude ratio resulting from changes in crack direction and dip angle differ, dependent on the offset rate. When angular differences among plural crack directions are within 90deg and dip angles within 60deg, the result of analysis represents the average characteristics of the plural cracks. 7 refs., 5 figs., 2 tabs.

    The effects of tsunami and seaquake on large floating structures are theoretically studied, where these effects are followed in terms of local strength using the equation proposed by Sells to predict surface shapes changed by seaquake-caused uplift of the seabottom. The equation is combined with the one for tsunami propagation, to better predict the tsunami motion. The simulation results indicate the necessity of considering the effects of tsunami for the design of a large floating structure. The authors discuss that the effect of tsunami is minimized when a floating structure is set at a depth of at least 40 to 50m, chain length should be determined by equalizing the breaking weight with the load at which the structure starts to move, and a structure should be set at a position where it is not attacked by transverse waves. They also discuss that seaquake intensity should be predicted by the equation of motion of compressible fluid, and, noting local strength of a floating structure, it will not be damaged when it is at least 16mm thick under the conditions of 2m as seabottom uplift and 0.5m as draft depth. 15 refs., 9 figs., 2 tabs.

    Change in wettability of coal particle surfaces due to kerosene adsorption was studied by using a film flotation method. The applicability of a film flotation method to coals modified by kerosene adsorption was first confirmed. In experiment, film flotation was applied to Illinois coal modified by aqueous methanol solution and kerosene adsorption, and the weight percent of residual particles on a gas-liquid interface and kerosene in aqueous methanol solution were analyzed to verify the applicability of a film flotation method. Film flotation was applied to Datong and Illinois coals modified by kerosene adsorption, and the weight percent of residual particles on a gas-liquid interface was plotted to surface tension of liquid. As a result, the weight percent of hydrophobic particles within 50mN/m in surface tension slightly increased in Datong coal and remarkably increased in Illinois coal with kerosene addition. It was thus suggested that in addition to surface tension, the distributions of hydrophilic and hydrophobic strengths on the surface of each coal particle should be considered to understand attachment of coal particles and bubbles. 6 refs., 4 figs.

    The paper evaluated performance of a flow-down collecting solar system. The solar heat pump PV system is composed of a solar system, heat pump and PV, of which the heat collecting portion is a water-use horizontal evacuated double glass tube solar collector. As a result of the performance measurement, the necessity of fundamental improvement arose. Under an idea of disproving common sense of the original forced circulation solar system, a system was designed in which heat is collected by making the heat media reversely circulate and flow down in accordance with gravity. When the flow rate was 2m{sup 3}/h, the collecting rate reached a maximum, approximately 54% (36.9% before improvement). When the flow rate was 1.3-1.5m{sup 3}/h, the system can realize the maximum merit, and the collecting efficiency became approximately 50%. Helped by reduction in consumed power, the average system performance coefficient reached more than 85% (28.9% before improvement). The obtainable energy rate rapidly increased to 2.9 times more than before improvement. Further, the consumed power of pump was decreased 65% from before improvement when the flow rate was 2.4m{sup 3}/h. 2 refs., 5 figs.

    For the foundation improvement works by grouting in a borehole, evaluation of grouting effect is one of the most important management items. The grouting design and works are sometimes reconsidered depending on the evaluation of grouting effect during the test injection. The purpose of the evaluation of grouting effect is to grasp the range of improvement and consolidation after the injection, and to judge and estimate the strength and permeability of the consolidation part. This paper describes the judgment method of the strength using PS logging results and borehole televiewer (BHTV) logging results. The reflection intensity (Ir) by the BHTV logging increased after the grouting, which showed a same tendency as that using S-wave and P-wave velocities (Vs and Vp) before and after the grouting. This was considered to demonstrate the grouting effect. A relation was obtained between the Vs, Vp and Ir before and after the grouting, which was expressed by following equation. Ir=0.143{times}Vs-70=0.093{times}Vp-110. The relation with the dynamic elastic coefficient (Ed) was also obtained as follow; Ir=0.0013{times}Ed. 9 figs.

    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.

    An attempt was made to visualize distribution of cracks in a rock slope by applying geophysical survey onto a rock slope. Geophysical logging and seismic survey using the reflection method were used as the methods for the geophysical survey. The rock slope subjected to the survey is located in a gorge along the Yoshino river in Yamashiro Town, Tokushima Prefecture. The slope has a width of 25 m and a height of 30 m. Its overhang in a nose form may has a possibility of causing collapse due to sliding. Cracks developed by horizontal schistosity were detected by performing geophysical logging on VSP, calipers, natural gamma-ray spectra, temperature and borehole in a borehole drilled vertically from the top of the slope. The seismic survey using the reflection method detected the cracks by emphasizing joints in the perpendicular direction. A possibility was shown to visualize the crack distribution with high resolution by using the above geophysical survey on the rock slope. In order to detect the crack distribution with still higher resolution, development into a three-dimensional exploration in the future is desired, not to speak of improvement in signal receivers, and discussions on geometry. 1 ref., 6 figs.

    In order to reduce the economic cost of the generating set etc. the damages to the materials and structures of the structure to last the original design life were observed and it was considered that if damages were fewer the life would be longer. One of the important items in assessing, amending and renewing the rationality of the established structure is the assessment of the defects and flaws existing in the welded joints. In Japan, WES 2805 which is named as the Method for Assessing the Defects for the Brittle Fracture Occurring Properties of Welded Joint was formulated in 1980 as the standard of the Japan Welding Society. Although it has been applied as the criterion in wide range, the part on brittle fracture is now under revision to reflect the research results on fracture mechanics thereafter and to perfect the fracture relationship because many years have passed since its first formulation. In this paper, the contents in the final stage of the revision of WES 2805 standard, including concrete examples, were introduced. 2 refs., 6 figs., 2 tabs.

They also discuss that seaquake intensity should be predicted by the equation of motion of compressible fluid, and, noting local strength of a floating structure, it will not be damaged when it is at least 16mm thick under the conditions of 2m as seabottom uplift and 0.5m as draft depth. 15 refs., 9 figs., 2 tabs.

    As for function and quality of information system, an assessment method of productivity at planning and at completion has been developed. In this method, functional size expressing the size of functional kinds provided by the system, value-added size expressing the size with corrected functional size in response to the quality level of each function, and production size expressing the size of products and processes under the given conditions were employed as indexes for evaluating the size of system. In addition, a method using the quality property tree has been developed. In this method, to evaluate the quality level which is essential for calculating the value-added size, users and providers evaluate the system quality from their own viewpoints. By this system, validity of user`s demand and validity/efficiency of realizing process can be evaluated for client/server type systems from the systematic viewpoint in a whole life cycle of systems from development planning to abandonment of systems. 24 refs., 5 figs., 3 tabs.

    A pressure sensor more reliable than the conventional types and a tire pressure measurement system using a plurality of sensors of the said reliable type have been developed. The sensor is an inverted T in shape, the upper surface of the vertical beam thereof receives the pressure, and the two ends of the horizontal beam are fixed. The load per unit area imposed on the pressure receiving surface is separated into three components, the X and Y components in the tangential direction are sensed by the vertical beam while the Z component in the vertical direction is sensed by a distortion gauge attached to the horizontal beam. For the measurement of the contact pressure distribution for the entire contact surface, a measuring device was developed, comprising a multiple point contact pressure gauge with 30 sensors of the reliable type discussed here embedded therein, a tire rolling tester, and a data processing unit. A tire wear estimation test was conducted using this pressure sensor and a contact probe type slip sensor, and it was found that a tire of a greater friction energy ratio is easier to experience abnormal abrasion and that the new pressure sensor is useful in estimating abnormal abrasion. Further, it was indicated that the present measuring device is applicable to the analysis of the mechanism wherein shaft force results from contact pressure on the soil. 3 refs., 11 figs., 3 tabs.

    Among the EDS, H-Coal and SRC-2 lined up in the coal liquefaction project of the U.S., the SRC is aimed at producing 6,000 t/day as a module for a 30,000 t/day commercial plant. They expect Ash contents (iron, sulfur, etc.) in coal without basically using catalysts. The products are applicable to fuels for electricity and gas for the moment. In the element technology, there are some problems in manufacturing hydrogen by gasification of residuals as well as in slurry systems, reaction towers, etc.. In the 30,000 ton commercial plant, the coal-liquefied oil costs $19.89/bbl (price as of 1978) assuming coal costs $29.47; therefore, the feasibility is strong as a substitute for petroleum. Japan's share for the required funds will be 86.8 billion yen (if 250 yen per dollar). Since the kinds of coal are conceivably increased in number through the improvement of the process, the Pacific rim countries and these which lie on the Indian Ocean are assumed to be the major coal producing countries for Japan. The stability in storage of coal-liquefied oil is experimentally excellent, as is the compatibility with petroleum products for example. Great results can be expected in the technical know-how and the spread of element technology for Japan. (NEDO)

    The on-and-off timing of vehicle headlamp control systems varies with weather conditions. Cloudy weather has a wider light energy distribution from visible to infrared radiation than clear weather. Silicon photodiodes, which can detect visible to infrared radiation, have larger output currents on cloudy evenings than on clear evenings under the same brightness conditions. The systems should be designed with such factors in mind as spectral characteristics of windshield, filters, sensor, and eyesight. 4 refs., 9 figs.

    Aiming at production of ethanol, fat and oil and so on, ten kinds of miscellaneous cereal crops such as pearl-millet, soybean and so on were grown, and comparative investigation of the production rate which was considered utilization of whole plants were carried out. The suitability of vegetable wastes as methane fermentation materials for the methane gas production was investigated by the constituent analyses and methane fermentation experiments. Nine kinds of the grasses and vegetable wastes such as tomatoe buds, broccoli leaves were used for the investigation. As the results, the estimated yield of ethanol per 10 are from pearl-millet was 690 liter, the estimated yield of fat and oil per 10 are was 70 liter from soybean, The results of the analyses of nine kinds of the farm residues were as follows: (1) carbon content of about 40 %, (2) C/N ratio of 13 av., (3) C/P ratio of 91 av., and (4) the content of C,N and P was roughly appropriate. 680 to 760 milliliter of methane gas was produced from one gram of the dry matter of tomatoe bods, and in case of broccoli leaves, 424 milliliter of methane gas was produced, it was found that these values were not inferior to animal dung.

    In order to evaluate disaster potential and disaster prevention potential of landslides, which are complicatedly composed of natural factors and social ones, an evaluating method of the potentials is proposed by applying the multiple logistic model. Furthermore, a method making the potential map using this evaluation is shown. The multiple logistic model is based on the conception of multiple risks, and so the disaster potential is expressed with probability. The disaster prevention potential is evaluated by using the disaster potential. Taking a typical landslide district as an instance, some potential maps colored by each potential are shown. By these maps, effects of the preventive measures against disasters and changes in the disaster prevention potential according to the industrial structure as well as the population are evaluated. Furthermore, combination of the other disaster potentials obtained by changing the surveying interval or factors makes it possible to draw various disaster maps and disaster prevention ones for different purposes. 15 refs., 17 figs., 3 tabs.

    Quantitative evaluation of physical and mental loads are effective in developing more human-friendly vehicles. Here attention has been focused on the mental load. Attempts were made to find some physiological indices that can be used for quantifying the mental load and resultant fatigue. Subjects were told to perform three different tasks in a climatoron, and the relation between physiological indices and their perception of fatigue as well as their capability of performing the tasks were analyzed. As a result, heart rate variability is a good index for quantitative evaluation of mental load and fatigue. 5 refs., 4 figs., 6 tabs.

To optimize the heat and electric power composite solar system, analyses were performed on heat production, devices and materials, and economy of the whole experimental facilities of the original model. Fundamental researches are being made on crystalline silicon, thin amorphous film and compound semiconductor solar cells. The solar thermionic generation element producing equipment installed in the previous fiscal year has produced and tested different types of electrodes, and operated the modules for an extended period of time. Measurement data of solar beam in ultraviolet, visible and near infrared zones were processed statistically, whereas the research work has been completed in the current fiscal year, having established successfully the reference solar radiation. In the hydrogen manufacturing technology using high-temperature direct pyrolysis, fundamental discussions were given on effects of electric and magnetic fields on dissociation of steam, and diffusion and separation of hydrogen by using permeation membranes. For hydrogen fuel cells, trial fabrication and tests were continued on single cells by using mainly the high frequency sputtering process. Experiments were continued on a solid electrolyte fuel cell system.

    This research and development is intended to establish a basic technology related to high crystalline polymeric material that has dynamic properties comparable to metallic materials by single polymeric material as a structural material. Thick and large high-elasticity molded forms were obtained by searching poly-arylate material, and by developing such processing technologies as high-pressure injection molding, composite injection molding, and elongation fluidity molding. High-elasticity molded forms with uniform internal orientation were obtained by heating and molding liquid crystal polymers under high magnetic field. Solution molding was performed on a molecular composite consisting of rigid chains and soft chains, which was laminated and bonded to have obtained an isotropic form with as high elasticity as 54 GPa. In addition, high pressure powder formation of cross-linked polymers of di-acetylene system provided an isotropic form with sound wave elasticity of 23 GPa.

    The aim is to improve on hydrocarbon oxidation which is a difficult reaction (analogous to combustion and having potential for heat generation or explosion, with restrictions therefore imposed on reaction conditions) by use of a catalyst supporting porous membrane. The fiscal 1999-2000 results are stated. In this effort, the target reaction is promoted by a catalyst supported by a porous membrane while combustion is controlled by the said porous membrane that separates oxygen and hydrocarbon from each other. Such a design was not available since a catalyst supporting inorganic membrane withstanding so high a temperature was difficult to prepare. Recently, however, a porous membrane with its pores regulated to microstructural dimensions was developed. The activity of a Pd membrane catalyst is evaluated in view of the degree of oxidation of propylene, cyclohexene, and benzene. It is then found that hydrogen that has passed the Pd membrane participates in the reaction. In a propylene oxidation test using a membrane type Ag/Al{sub 2}O{sub 3} catalyst, it is found that acetone is generated and that oxygen after passing through the membrane participates in the reaction. Methods are studied for preparing a metal membrane in which the catalyst system comprises a catalyst supporting porous membrane and a Pd membrane. In the fabrication of metal membranes, a highly selective hydrogen permeable membrane is stably prepared by the thermal CVD (chemical vapor deposition) method. (NEDO)

    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.

    This paper reports a method to detect reflected wave components contained in an elastic wave caused in association with well drilling. Measurement was made on an elastic wave caused in association with well drilling in an experimental field by using a triaxial elastic wave detector disposed in a measurement well. Analyzing the particle motion tracks in the derived elastic wave signals (to derive the main axial direction of a three-dimensional hologram) revealed that oscillation direction of the signals changes non-steadily by time centering around the S-wave oscillation direction. In addition, a sound source position was estimated during the drilling. Existence probability of the S-wave signal in the non-steady continuous signals was estimated by handling the particle motion tracks stochastically. In addition, this existence probability was used as a weighting function for a correlative analysis to detect a reflected wave from directly reaching wave components in the non-steady continuous signals. Thus, improvement in reliability of reflected wave detection was attempted. Effectiveness of this method was endorsed by the field data. 3 refs., 7 figs.

    This paper reports the achievements in fiscal 2000 in development of a technology to evaluate reliability of petroleum refining facilities. The development efforts were made mainly on analyses by simulation and neural net (NN) that utilize computers. In the high-temperature system facilities, the creep damage generation is governed by different factors including impurities. The evaluation on joint life requires simultaneous use of low temperature zone long-time test. Verification was made on application of non-destructive inspection, such as use of ultrasonic waves in the accelerated creep zone. Defect detecting capability was identified when an ultrasonic wave flaw detection model is used for buried piping. In the pulse eddy current flaw detection, a coil most superb in totality was selected by means of simulation, by which corrosion and wall thickness of piping and devices were detected from outside the sheathing materials. Development was made on a technology to diagnose and evaluate corrosion of tank in operation by using the AE method. The remaining life of transformers is determined by how seriously the coil insulating paper has been deteriorated, and furfural in the oil was found effective for the parameters. Particularly, application of the NN was revealed to be effective in estimating electric motor deterioration. A high-temperature sulfide corrosion rate estimating model was developed from the operation and measurement data of the facilities by applying the NN and TCBM. (NEDO)

    With an objective to know coal condensation structure which has influence on coal conversion reaction, an attempt was made on quantitative evaluation of hydrogen bonding in coal. Using as test samples the VDC made from Taiheiyo coal swollen by tetralin and vacuum-dried, and its pyrolyzed char, DSC measurement and Fourier transform infrared spectroscopy (FT) were performed. An FT spectrum comparison revealed that the VDC swollen at 220{degree}C has the hydrogen bonding relaxed partly from the original coal. However, since the change is in a huge coal molecular structure restraining space, it has stopped at relaxation of the bonding energy without causing separation as far as free radicals. On the other hand, the DSC curve shows that the VDC has slower endothermic velocity than the original coal. In other words, the difference in heat absorption amounts in both materials is equivalent to the difference of enthalpy ({Delta} H) of both materials, which corresponds to the relaxation of the hydrogen bonding. Therefore, the {Delta} H was related to wavenumber shift of the FT spectra (which corresponds to change in the hydrogen bonding condition). By using this relationship, a method for evaluating hydrogen bonding distribution was proposed from an O-H contracting vibration change that can be measured by using the FT spectra and a thermal change that can be measured by using the DSC. 3 refs., 7 figs.

    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.

    Performance of various catalysts for hydrogenation of recycle solvent was evaluated for the operation of NEDOL process 1 t/d process supporting unit (PSU). Distillate between 220 and 538{degree}C derived from the liquefaction of Tanito Harum coal was used as recycle solvent. Deactivation behaviors of catalysts were compared using a prediction equation of catalyst life, by which aromatic carbon index (fa) after hydrogenation can be determined from the fa of recycle oil before hydrogenation, reaction temperature, and total hydrogenation time. Total hydrogenation time satisfying the {Delta}fa, 0.05 before and after hydrogenation were 8,000, 4,000, and 2,000 hours for NiMo-based catalysts C, A, and B, respectively. Catalyst C showed the longest life. Used catalysts were also characterized. The catalyst C showed larger mean pore size than those of the others, which resulted in the longer life due to the delay of pore blockage. From measurements by XPS and EPMA, relative atomic concentration of carbon increased remarkably after the use for all of catalysts, which was considered to be due to the adhesion of hydrocarbons. Increase of metal atoms, such as Fe and Cr, was also observed due to the contamination of entrainment residues. Deactivation of catalysts was caused by the adhesion of hydrocarbons, and metallic compounds, such as Fe and Cr. 3 refs., 1 fig., 5 tabs.

    The fiscal 1998-2000 results of efforts to develop cluster diamond (CD)-diffused solid lubricant composite materials expected to exhibit excellent lubrication are stated. Since friction greatly affects machine life and energy efficiency, friction reduction is an important task. Very hard and microscopic CD was utilized for the achievement of a friction coefficient of 0.08. A manufacturing technology for molds 10nm or smaller was developed, which enabled the development of a gear not larger than 8mm. The success will enable the operation of micromachines in the absence of lubrication which is impossible at present. A CD-aided functional layer creation technology was also developed. It is expected that the development and practical application of micromechanisms will make rapid progress in the 21st century. Much is expected from the creation, and goods with the achievement applied thereto, of advanced technologies whereinto non-lubrication, functional layer creation, and excellent heat conductivity are incorporated. It is quite significant that, since CD is available in any field as far as light-load low-speed sliding conditions are satisfied, sliding parts will be improved and service life will be prolonged.

    With the purpose of preparing the main points of 'environmental-impact assessment guidelines for wind power developments (draft)', examples of environmental-impact assessments, related laws and regulations in Japan and abroad were collected, and rearranged in respect to requirements in environmental-assessments, concrete procedures, survey/projection/assessment method, summarisation of results, etc. It was clarified, for example; in a large-scale wind power development, it can be dealt with by choosing items and contents on the assumption that a land area is developed; in a small-scale development, there is basically no need of considering the possible effect of the construction work; and, as far as noise, vibration and the ecosystem (plants/animals) are concerned, however, the characteristics of the site be taken into consideration. Objects for general assessment are noise, low-frequency air vibration, radio wave interference, the ecosystem (plants and animals) and the landscape. The guideline draft is constituted of (1) basic items, (2) overview of the area, (3) determination of items for environmental-impact assessment and (4) research, prediction, assessment, conservation measures and follow-up research; in the basic items, importance of preliminary consideration was emphasized, as were priority/simplification, implementation of environmental conservation measures, and implementation of follow-up research.

    Chlorinated organic compounds has high priority for toxicity screening among environmental hazardous chemicals. In the present study, we used immortalized rat hepatocytes as a liver model in vitro to evaluate the toxicity of nine chlorinated organic compounds. Toxicity of nine chlorinated organic compounds were evaluated to cellular viability of immortalized rat hapatocytes. The potency of the toxicity based on 50% inhibitory concentration (IC50) value was in the following order: triclocalban>triclosan>3,4-dichloroaniline>2,5-diclorophenol> 2,5-dichloroanisole>p-dichlorobenzene> p-chloroaniline>o-dichlorobenzene=tris (2-chloroethyl) phosphate. The rank order of cytotoxic potency of nine chemicals was compared with toxicity information using animals. The rank order of cytotoxic potency did not relative to the order referenced mean lethal dose (LD50) as an index of acute toxicity of rats or mice. However, the rank order of cytotoxic potency relatively correlated non-observed adverse effect level (NOAEL) under the exposure duration adjusted for chronic toxicity in vivo. These data suggests that the origin of testing cell had better to make match target organ of toxic chemicals for extrapolation from data of bioassay in vitro to in vivo. 16 refs., 2 figs., 3 tabs.

Chapter 1 describes the results of the (Project Lignite), i.e., development of the concept of two-stage liquefaction of lignite. Chapter 2 describes the COSTEAM process, which uses synthesis gas (CO-H{sub 2}) as the reducing agent and coal moisture as the hydrogen source for liquefaction of coal of low degree of carbonization, e.g., brown coal. Chapter 3 describes solubilization of coal with alcohol, where coal is reacted with ethanol and NaOH at 300 to 420 degrees C. Chapter 4 describes liquefaction of coal and production of lighter products with tetrahydroquinoline as the hydrogen donor. Chapter 5 describes low-temperature carbonization as the process for liquefying coal, in particular brown coal. Chapter 6 describes possibility of development of new liquefaction techniques for brown coal, including solvolysis for liquefaction, role, recovery and reuse of catalysts, short contact time processes, and coal pretreatment. Chapter 7 describes economic viability of the secondary hydrogenation. (NEDO)

    As a method to evaluate the rock mass, electromagnetic tomography and resistivity tomography were tested on the original site. The electromagnetic tomography can tomographically analyze the propagation velocity and initial amplitude damping. The resistivity tomography uses a finite element method from the initial resistivity distribution model and finally gives a model which is nearly equal to the actual resistivity distribution. Both the above tomographic analyses can detect the crushed spot as a low velocity, high damping and low resistivity spot. However, the electromagnetic tomography could detect finer structure than the resistivity tomography. The water content of rock mass was evaluated from the damping coefficient which was given by the amplitude damping tomography of electromagnetic wave. If it is compared with the water content which is given by the dielectric constant of velocity tomography, there partially exists discrepancy between both, because the damping coefficient contains information on cracks which disperse and reflect the electromagnetic wave. Between the resistivity and porosity, there exists a known experimental formula, which was satisfied by the presently given resistivity. 9 refs., 10 figs.

    A 70 kW-class photovoltaic (PV) power generation system of the Tsukuba Research Cooperation Center, Agency of Industrial Science and Technology was evaluated using hourly measurement data. Hourly solar irradiation, mean PV module temperature, hourly array generated power, hourly PV system generated power were selected as the measurement items, to examine the validity of measurement method. Furthermore, based on these measurement data, the loss factors were estimated, which reduce the system efficiency. They included the losses due to the shadow effect, the deterioration of module efficiency with the raise of temperature, the mismatch of tracking control of the maximum power point, and the reduction of inverter efficiency with the input power phenomena. To estimate these loss factors from hourly measurement data, the system was evaluated by defining characteristic parameters. As a result, it was found that the main factors were the shadow effect and the mismatch loss, which reduce the mean annual output factor of the system to 65%. 3 refs., 6 figs., 1 tab.

    An evaluation was given on effects of hydrogen on pipeline materials in order to determine a most base value in an optimal cathodic protection potential in cathodic protection of buried pipelines. Protection potentials were estimated from the relation between critical hydrogen amount and the potentials in marine clays and sodium acetate as electrolyte. The materials were evaluated using a strain rate tensile experiment method. The following results were obtained: The more base the potential, the elongation was somewhat less than the result in air, while the tensile strength increased slightly; difference in water content in soils varies the cross section contraction rate; the rate does not change in a marine clay containing water at 20%, but it decreases in a 30%-content soil; an SEM observation revealed pseudo cleavage faces; and the critical hydrogen amount that causes hydrogen cracking is 10 ppb, which corresponds to -1.4V in a marine clay containing water at 30%, and -1.2V at 14%. A loading experiment with actual loads verified that no fracture due to hydrogen cracking occurs even under an overprotection environment when a load imposed on an actual pipeline is kept constant. 16 refs., 10 figs., 3 tabs.

    The objective of this investigation is to estimate the creep life of glass fiber reinforced plastic (GFRP) under stress-corrosive environments using acoustic emission(AE). The laminates were fabricated using combinations of vinylester resin (R806) and random fiber mat or woven cloth. The creep tests were conducted in 5% nitric acid (HNO{sub 3}) environment. The AE depends on the loading level and the environment condition. For the creep test, the woven cloth reinforced specimens gave higher number of AE counts than the random mat reinforced specimens. The creep life decreased with increasing creep stress, whereas the rate of AE counts increased with increasing creep stress. A linear relationship was found between the creep life and the AE count rate. Using the proposed equation, a prediction of the creep life of GFRP under corrosive environments would presumably be possible. (author)

    Ikeda, et al., in their examination of log data obtained from a borehole (2000m deep) drilled at Ashio, Tochigi Prefecture, where micro-earthquakes swarm at very shallow levels, pay special attention to porosity. Using correlationship between the porosity and elastic wave velocity/resistivity, the authors endeavor to find the presence of secondary pores, dimensions of faults, composition of water in strata in faults, and difference in matrix between rocks, all these for the classification and evaluation of fault fracture zones. In the present report, log data from a borehole (1800m deep) drilled to penetrate the Nojima fault (Nojima-Hirabayashi, Awaji island) that emerged during the Great Hanshin-Himeji Earthquake are analyzed in the same way as the above-named Ashio data, and the results are compared with the Ashio results. Immediately below the Nojima-Hirabayashi fault fractured zone, stress is found remarkably reduced and the difference stress quite small in size. This is interpreted as indicating a state in which clay has already developed well in the fault fractured zone ready to allow the occurrence of shear fracture or a state in which such has already occurred for the release of stress. 4 refs., 5 figs.

    Remote sensing images include information of coastal land division, sea level change such as sedimentary environment and vegetation, and distribution of artificial structures. Past sea level changes and their causes can be regionally obtained by analyzing these data and by integrating them with information obtained from geological survey. In this study, causes and history of past sea level changes, formation mechanism of coastal topography, and past sea level change survey in Thailand have been reviewed. This paper describes an extraction method of the sea level change information in coastal districts by analyzing several actual remote sensing images. For understanding the current sea level rise, it is required to clarify the causes quantitatively among three causes of sea level changes, i.e., volumetric change of total ocean water on the earth, relative sea level change due to the crustal deformation, and change of irregularity of sea surface with ocean current. It is also required to compile maps in Asian or global scales. 13 refs., 6 figs.

    The results of investigating time management (permissible value of ignition time and prepurge time) for safety control of combustion relating to a combustor is reported. It is shown that the heating value of hydrocarbon-based fuel is determined by molecular weight irrespective of molecular structure and constant (11200kcal/kg) per unit weight; the heating value of mixture gas of theoretical mixture ratio is constant (1000kcal/m[sup 3]) indifferently of the kind of fuel; and that the product of the heating value of a fuel and the lower limit of its explosion limit is approximately constant (400-600kcal/m[sup 3]). Succeedingly it is shown based on these values that allowable ignition time is determined by the combustion chamber load (ratio of the maximum amount, 10[sup 4]kcal/h, of combustion to the volume of combustion chamber); the effect of dilution by exhaust lengthens it by only about 50%; and that the conventional criterion that the frequency of ventilation of prepurge should be 4-5 or that the minimum time of prepurge should be 30 seconds is appropriate. 6 refs., 4 figs., 1 tab.

The techniques for the category (1) include those for vertically dispersed databases, database systems for multiple addresses in a wide area, and open type combined database systems, which have been in progress generally as planned. Those for the category (2) include the techniques for color document inputting and information retrieval, meaning compiling, understanding highly overlapping data, and controlling data centered by drawings, which have been in progress generally as planned. Those for the category (3) include the techniques for improving resistance of the networks to obstruction, and security of the data in the networks, which have been in progress generally as planned. Those for the category (4) include the techniques for rule processing for development of protocols, protocols for mutually connecting the systems, and high-speed, high-function networks, which have been in progress generally as planned. It is expected that the original objectives are finally achieved, because the development programs for these categories have been in progress generally as planned. (NEDO)

    In order to make clear the difference of the response time between the oxygen sensors with different protection covers, we visualized gas flow inside of sensor covers by means of two experimental methods: One is `Smoke Suspension Method` using liquid paraffin vapor as the smoke. With smoke suspension method, we detected the streamlines inside of the covers. The other is `Color Reaction Method` using the reaction of phenolphthalein and NH3 gas. With color reaction method, we confirmed the streamline inside of the cover and furthermore detected the difference of the response time of each sensor. 3 refs., 7 figs., 1 tab.

    The engine structure attenuation has been experimentally analyzed by the newly developed in-cylinder excitation system. It can reproduce the complete cylinder pressure in non-running engine conditions by adopting the hydraulic and the piezoelectric actuator. The structure attenuation measured in this system has a good coincidence with the ones measured in actually engine operating conditions, meanwhile the current method, which applied only high frequency components as the excitation pressure, was shown to have the unsatisfied agreement. As a result, the proposed system has been concluded to be very useful to estimate the engine noise characteristics in non-running conditions. 4 refs., 11 figs., 1 tab.

    CO2 emission was quantified through the life cycle of a solar water heater to assess its environment impact. Although LCA (life cycle assessment) originally sums up I/O of all materials and energy through the whole life cycle of a product to examine environment impact, this assessment was carried out for only CO2. Calculation of CO2 emission assumed a natural circulating solar water heater of 200 l in effective hot water capacity, 2.78m{sup 2} in effective collecting area, and 0.5 in average annual collecting efficiency of total solar radiation, and an auxiliary city gas heat source for compensating insufficient heat quantity. The total CO2 emission in the life cycle of a solar water heater was obtained from an industrial association table assuming the life cycles of 10 and 20 years. CO2 emission was estimated to be 5407.1kg-CO2 and 10665.2kg-CO2 for 10 and 20 years, respectively. CO2 emission due to city gas was largest in the total CO2 emission in the life cycle. As a result, for reduction of CO2 emission due to a solar water heater, improvement of equipment efficiency was most important. 6 refs., 5 figs., 3 tabs.

    Described herein are characteristics of photovoltaic (PV)/thermal hybrid collectors (PV/Ts), in which a PV module is combined with a plate-shape solar heat collector to simultaneously produce electric power and heat. Their efficiency is assessed by exergy. The test results indicate that the PV/T system gives a 1.07 times higher exergy than the PV system, 86.3 versus 80.7kWh. In terms of energy, the optimum values (OVs) are 5, 44 and 37% lower than the measuring values (MVs) for electrical energy, thermal energy and total exergy. In terms of exergy, on the other hand, OV is 5% lower than MV for electrical energy, but 893 times higher for thermal energy and 1.26 times higher for total exergy. As a result, the exergy level is 26% higher than that of a system which generates power as the main product and heat as the auxiliary product. 3 refs., 6 figs., 5 tabs.

All the inventory items are being rearranged into a convenient order, and efforts are under way to designate the association to be in charge and the method to be used for data collecting (the accumulation method, process model method). Problems about techniques in the veinous department are extracted. The flow of matters relating to various metals and glass after their use and the magnitude of their environmental impacts at the ultimate sites of treatment are understood though roughly. Investigations are conducted into typical formats overseas, a data arranging format is constructed, specifications are defined for a data inputting software program, and a request is placed with a dedicated dealer for the compilation of the said program. The architecture and specifications of an LCA (life cycle assessment) database system are determined, and its functions are undergoing an intermediate check by a research team for improvement. Endeavors are exerted at quantifying global warming, ozone layer depletion, biotoxicity, and photochemical oxidants for use as the basic data for damage evaluation. (NEDO)

    The abnormal sisal, which was observed in the ESR measurement of superconductors, was confirmed to be a non-ESR (non resonant) signal, from an ESR experiment applying parallel and vertically polarized microwave fields and from the calculation of the ESR transition probabilities. The field modulation dependence of the spectra revealed that the signal was composed of two components. From the modulation-scheme analysis and a study of type I and II superconductors, two components were assigned to the microwave responses to magnetizations trapped in the crystalline portion and at intergranular Josephson junctions. The former B and the batter J components are observed in the first derivative and absorption a form, respectively, and their polarities differently behave for the field sweep reversal. Based on these results, we have improved an ESR spectrometer, which makes it possible to measure separately two kinds of magnetization and to study the trapping ability and quantum flux. 11 refs., 12 figs., 1 tab.

    A discussion was given on value of participation of an IPP as seen from an electric power system operation plan prepared by utilities. In the discussion, evaluation was made using as the breakeven cost of IPP power purchase prices the difference in power generation cost between electric power systems in which an IPP is participating and not participating, or in other words, the reduced portion of the power generation cost. As a result of the discussion, the following matters were indicated: in the case where an utility company expands its capacity by installing a coal-fired thermal power plant which is lower in operation cost, to deal with increase in power demand, the breakeven cost could be an avoidable cost for the utility company; if the expansion by installing a coal-fired thermal plant is not possible, the breakeven cost for a base type IPP would rise; the breakeven cost for a peak type IPP would be higher than for the base type IPP because the breakeven cost can serve to cut the peak for generators owned by the utility company; and participation of an IPP to power sources in remote areas would provide a large effect to reduce power transmission loss in an entire system, thereby increasing the breakeven cost. 1 ref., 9 figs., 3 tabs.

    This paper describes a proposal of a method for evaluating environmental performance of technologies by using the interindustry relations table, and the case studies thereof. This method is characterized in that it can evaluate two effects affecting the environment: structuring of capital facilities required in association with introduction of the technologies and the changes in social structures. As a parameter to compare the technologies considering these effects, a concept of life cycle limited emission amount was introduced. In the case studies, life cycle limited CO2 emission amounts from using seven kinds of technologies were calculated, and environmental performances of each technology were compared. The result indicated that introduction in Japan of coal, oil and LNG fired thermal power generation will increase CO2 emission amount from the whole society. Conversely, introduction of hydraulic, nuclear, photovoltaic, and wind power generation technologies will reduce the CO2 emission amount. It is pointed out particularly that hydraulic and nuclear power generation can minimize CO2 emission from structuring capital facilities, and is an excellent technology from a viewpoint of reducing CO2 emission from the society as a whole. 5 refs., 6 figs., 1 tab.

    Under an assumed plan of building a geothermal power station in the Shiramizugoe area of Makizono-cho, Aira-gun, Kagoshima Prefecture, investigations will be conducted under a 4-year program into the amount of geothermal resources, the dimensions and cost performance of a geothermal power station under consideration, and the environmental impact that the locating of such will incur, through for example identifying areas containing geothermal reservoirs suitable for geothermal power generation. In fiscal 1999, activities were conducted in the three fields of (1) survey plan preparation, (2) comprehensive analysis, and (3) environmental assessment. Under item (1), a survey and coordination implementation plan was prepared, existing data were analyzed for the construction of geothermal models out of which a suitable geothermal structure was specified for digging, and a list was drafted of locations for borehole digging for fiscal 2000. Under item (2), it was found that most of the past surveys covered the Ogiri area and that the Shiramizugoe area was but poorly covered. Discussion was made on the geological structure, geothermal structure, geothermal water hydraulic structure, and the geothermal water system. Under item (3), the plan was summarily explained to the local administration, associations of hot spring hotels, and inhabitants in the vicinity, and their consent was obtained. (NEDO)

    Discussed is a method for evaluating wind noise in passenger car compartment based on human auditory characteristics. In the study, noise in the compartment of a passenger car travelling at a constant speed is collected by use of a dummy head, and the collected noise is analyzed in view of the masking effect, directional sensation produced by binaural hearing, etc. A masked spectrum of noise in the compartment of a 6-cylinder vehicle travelling at 120km/h is analyzed, and it is found that some frequency bands, especially the band centering on 300Hz, are masked by a loud noise component falling in a low frequency band of 180Hz or lower. By use of masked spectrum analysis, the level of noise that is actually audible to human ears can be calculated. The noise level thus determined by masked spectrum analysis and the noise direction determined by a binaural signal processing model are examined, and then it is found that the noise direction is clearly determined when the noise belongs in a 450Hz band or higher where wind noise prevails. On the bases of the above-mentioned results and the directional sensation produced by binaural hearing, a `binaural wind noise evaluation method` is compiled. 20 refs., 9 figs., 1 tab.

    Efforts were exerted in fiscal 1984-1992 to develop techniques for appropriately assessing a geothermal reservoir for its productivity for duly predicting the optimum scale of power generation to be provided thereby. In the development of simulators, geothermal reservoir simulators (SING-1, -2, -3) and a geothermal well 2-phase flow simulator (WENG) were developed. As for the treatment of fractures in a reservoir and of substances soluble in the hot water, the methods for dealing with them were improved and augmented. In a model field study in a Hokkaido forest, reservoir pressure continuous observation and monitoring, temperature logging and pressure logging for existing wells, and geothermal fluid chemical analysis were performed for reservoir analysis, in which both natural state simulation and history mapping excellently reproduced the temperature and pressure distributions. The temperature and pressure distributions in a natural state simulation, out of the results of an analysis of the Oguni district model field, Kumamoto Prefecture, agreed not only with those in the natural state but also with the pressure transition data in the observation well.

    The computer aided coal structure construction system is proposed, and a computational construction example is presented. The coal structure construction engine of this system fabricates molecular structure by connecting fragments sequentially inputted through a user interface. The best structure candidate is determined using construction knowledge and partial energy evaluation every addition of one fragment, and this process is subsequently repeated. The structure evaluation engine analyzes the 3-D conformation candidate by molecular dynamics, and evaluates the conformation by determining the energy value of an optimum structure. As an example, this system was applied to construction of coal molecular structure based on the actual data of partial structure composed of 26 structures from 2l kinds of aromatic cluster structures, 27 bonds from 2 kinds of bridged bonds, and 16 groups from 2 kinds of terminal substitutional groups. As a result, this system could construct a superior structure according to expert knowledge from the viewpoint of energy. 6 refs., 5 figs., 2 tabs.

    With the purpose of preparing the main points of 'environmental-impact assessment guidelines for wind power developments (draft)', examples of environmental-impact assessments, related laws and regulations in Japan and abroad were collected, and rearranged in respect to requirements in environmental-assessments, concrete procedures, survey/projection/assessment method, summarisation of results, etc. It was clarified, for example; in a large-scale wind power development, it can be dealt with by choosing items and contents on the assumption that a land area is developed; in a small-scale development, there is basically no need of considering the possible effect of the construction work; and, as far as noise, vibration and the ecosystem (plants/animals) are concerned, however, the characteristics of the site be taken into consideration. Objects for general assessment are noise, low-frequency air vibration, radio wave interference, the ecosystem (plants and animals) and the landscape. The guideline draft is constituted of (1) basic items, (2) overview of the area, (3) determination of items for environmental-impact assessment and (4) research, prediction, assessment, conservation measures and follow-up research; in the basic items, importance of preliminary consideration was emphasized, as were priority/simplification, implementation of environmental conservation measures, and implementation of follow-up research.

    In order to enhance the environment and wear resisting performance of the bearing mechanism for petroleum excavation bits assuming use at a depth of 6,000 m, discussions were given on a cubic boron nitride based ultra-hard thin film and a Ti{sub x}M{sub 1-x}N based hard thin film as the new materials. This paper describes the evaluation report for the year 2000. It was found that the promising material is the Ti{sub x}M{sub 1-x}N. The practical applicability test would require a considerable amount of expense and insurance fee, while putting the material into practical use would take some more time. However, the achievements in developing this new material will allow the material to be applied to cutting tools used under the same onerous condition, and theoretical development would be possible on the consideration of the film properties, whereas further development may be expected in the future. An international joint study has performed evaluations on the environmental resistance and the characteristics of the film at the University of Toronto. These evaluations are effective in enhancing further the properties of the thin film in the future. Achievements have been accumulated steadily from starting the fundamental studies, and high level objectives have been achieved. Accurate identification has been made on the state of developing the parts for petroleum excavation bits, with the objectives set properly. Putting the bits into practical use will still require public assistance. (NEDO)

    Reliability and safety are evaluated for main diesel engines, generator diesl engines, their mechatronics and auxiliary machines on ships. The evaluation is based no statistical analysis of field data collected from outland navigation by MO diesel engine the period of 1983-1988. Evaluation indexes are used for analysis, such as failure rate (total number of failure/total navigation hour), mean maintenance man power: mh (total maintenance man power for determined period/total number of failure), manning index: MI (maintenance manpower for repairing failure occurred during 1000 hour navigation). With respect of total failure of ship plant as a whole, the failure rate decreased from 13.2 to 7.4, namely almost to half and mh was tending to increase from 5.5 to 5.8, while MI decreased from 73.0 to 43.1. With respect to heavy failure which is regarded as a scale of safety, the failure rate remained within a range of 0.7-0.5 and mh showed down-up movement like 30{yields}10.4{yields}18.8, while MI moved like 18.6{yields}5{yields} 10.9 . 3 refs., 9 figs., 3 tabs.

    The ability that architectural space improves the thermal environment in comparison with outdoor environment is called the `capability of controlling thermal environment.` As the value becomes higher, the indoor thermal environment is more improved. In this paper, the controlling capability of six building envelopes with different window systems was compared. The heat transfer in the wall and window system is approximated using a lumped mass model of heat capacity to obtain a heat balance equation and combined with the heat balance equation in indoor air for backward difference. The wall surface temperature and indoor air temperature in a calculation model are then calculated. A radiation absorption coefficient is used for mutual radiation on each wall. In the model, the adjoining room or first- and second-floor rooms were made the same in conditions as the model on the assumption that the one-side lighted office in an RC reference floor is in the non-illumination and non-airconditioning state. In summer, the controlling capability remarkably varies depending on the window system. For the window facing the south, the annual capability is more advanced than in other directions and the indoor thermal environment is improved on the average. 7 refs., 12 figs., 1 tab.

    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.

The techniques for these systems fall into four categories of those related to (1) dispersed data systems, (2) multimedia, (3) high reliability, and (4) elementary techniques for mutually operable network systems. The techniques for the category (1) include those for vertically dispersed databases, database systems for multiple addresses in a wide area, and open type combined database systems, which have been in progress generally as planned. Those for the category (2) include the techniques for color document inputting and information retrieval, meaning compiling, understanding highly overlapping data, and controlling data centered by drawings, which have been in progress generally as planned. Those for the category (3) include the techniques for improving resistance of the networks to obstruction, and security of the data in the networks, which have been in progress generally as planned. Those for the category (4) include the techniques for rule processing for development of protocols, protocols for mutually connecting the systems, and high-speed, high-function networks, which have been in progress generally as planned. It is expected that the original objectives are finally achieved, because the development programs for these categories have been in progress generally as planned. (NEDO)

    We have proposed the 'complementary menu system' as an easy-to-build and easy-to-use menu system. It has two component menu systems, one is based on a word taxonomy and the other is based on the document structure (e.g., the table of contents of the target document). By the user's selection of an item on a menu, the positions and relevance of related items are shown on the other menu, which makes users easier to select proper menu items. We have also shown the combination of context-sensitive menus reduces user's errors of selection of menu items by several experiments. In this report, we investigate the choice of word taxonomies effective for novice users and the design of structure and interface of menus to reduce overlooked related items. 1. Comparative experiment among a complementary menu using a general-purpose word taxonomy used in a thesaurus and the ones using domain-specific taxonomies based on quick references used in the target document, shows that even novice users prefer domain-specific word taxonomies and exhibit higher performance in retrieval significantly. 2. Comparison between a domain-specific word taxonomy that arranges different categories in a line and another domain-specific word taxonomy which reorganizes the categories under one parent category, suggests users relatively prefer the latter taxonomy but the preference depends on the amount of user's domain specific knowledge. 3. Component menu system which has only one menu showing the whole taxonomic hierarchy with scrollbars on which the positions and relevance of related items are shown is effective to reduce the number of overlooked items.

    For contribution of suggestions for establishing directions and concrete tasks for new industrial technology research and development projects, a survey is conducted about trends of industrial technology development and into research domains where importance will gather in the future, for which development trends are studied such as limiting, providing of intelligence, and advanced composition. In this report, domains expected to become important in the future are investigated. Important subjects are found in the domains of the space limiting (micromachining, atom/molecule manipulation, microanalysis, etc.), the time limiting (super-spacetime processing, quantum device, femtosecond technology, 4-dimensional device, etc.), biomimetics and providing of intelligence (intelligent material, neural network, genetic algorithm, artificial life, sensor fusion, intelligent robot, etc.). In addition to these, 'ultrastructure that learns from organisms,' 'intensive interaction system,' and 'nonlinearity/chaos technology' are proposed as promising fields of development. Since Japan is traditionally strong in hardware technologies relating to micromachining and substance/material processing, good results will be attained when the industrial, governmental, and academic circles exert endeavors.

    Hydrogenolysis of different rank coals as Taiheiyo coal (75.7C%) and Pittston coal (85.4C%) were conducted in the presence of four kinds of catalysts (CuCrO4, Fe2O3+S, MoO3-TiO2 and MoS3-Al2O3) with an addition of tetralin as vehicle. The variation in viscosity in every reaction system was traced in the initial stage of the reaction by a torque meter attached to an autoclave. As a result, in every system, the torque decreased in the initial stage of temperature rise because of reduction of a solvent viscosity. The torque subsequently increased with temperature indicating two peaks before the following gradual decrease. In Taiheiyo coal, both peaks were low, and its coal conversion was more than 85%, while in Pittston coal, both peaks were sharp and high, and both subsequent torque reduction and coal conversion were smaller than those of Taiheiyo coal. 5 refs., 10 figs., 2 tabs.

    A discussion was given on the fundamental properties of mortar made from cement mixed with silica fume. Four kinds of silica fumes with different particle size distributions were used. The following results were obtained: distribution of pores in mortar admixed with silica fume shifts to the smaller radius side; while the admixture increases the compression strength in mortar, the increasing trend varies depending on the kinds of silica fumes; this is thought to be caused from the difference in pozzolan activity between silica fumes; and the strength increase is caused by densification of the structure due to the pozzolan reaction that is generated after hydration, or in other words, decrease in the pore volume. The applicability of the mortar was investigated as a filling mortar to fill up clearances between wastes. It was found that the filling performance can be controlled by mixing silica fume at an adequate level and adjusting the viscosity. The diffusion coefficient for the admixed concrete is smaller by 30% to one digit than that for the ordinary concrete. High-performance water stopping concrete of 0.11 {times} 10{sup 4}cm {sup 2}/s at maximum was obtained. The concrete can be regarded as a material having superb filling and water stopping performances. 6 refs., 4 figs., 5 tabs.

    The ceramic gas turbines (CGT's) for, e.g., cogeneration and portable power generation systems are studied and evaluated for their environmental preservation, energy saving and economic characteristics. Types of utilization and market sizes are also studied for, e.g., portable power generation systems. The items studied include current status of cogeneration systems in USA, and recognition of cogeneration systems in Japan. The study results lead to the conclusions that the biaxial CGT for portable power generation systems is a promising substitute for diesel engines as the power source in the future, and 300kW class CGT's will have the markets of 170,000 units and potentially 450,000 units, because of their expected wide applicability. The studies on their economic, energy-saving and environmental load reduction effects indicate that one unit brings the economic effects totaling 616,000 yen, due to reduced fuel consumption and NOx abatement. They could reduce NOx emissions by 8,090 t/y for automobiles and 6,570 t/y for the others, when they fill the potential markets. (NEDO)

    This paper reports the result obtained during fiscal 1994 on research on research on optimization of bandgap in thin film compound solar cells. In research on Cu(InGa)Se2 thin film solar cells by using a gas phase selenide making process, discussions were given on optimizing the following three processes: a process to raise temperature of a precursor film formed at a substrate temperature of about 150{degree}C, a selenide making process to perform annealing at about 500{degree}C, and a temperature reducing process. Good characteristics were obtained when selenium amount in the precursor is about 50%. In a bandgap control viewpoint, it was found that the conversion efficiency decreases rapidly when Ga composition is higher than 50%. A conversion efficiency of 14.9% was obtained to date at the Ga/(In+Ga) ratio of 0.4. In research on Cu(InGa)Se2 thin film solar cells by using a simultaneous deposition method, a conversion efficiency of 13.5% was obtained at a bandgap width of about 1.3 eV during research on manufacturing ZnO/CdS/Cu(InGa)Se2 thin film solar cells by using the simultaneous deposition method.

    Described herein are the results of the FY1994 research program for research on advanced solar components as part of research and development of solar thermal energy. The catalyst for liquid-film reactions is prepared, and the flask tests are conducted as the preliminary experiments for development of the reactor in which 2-propanol is fallen in liquid film over the catalyst dispersed to accelerate its decomposition. It is decomposable when fallen in liquid film even in the presence of 35% of acetone. The catalyst of ruthenium carried by activated coal is used to produce 2-propanol under an exothermic condition from acetone and hydrogen. Diisopropyl ether and 4-methyl-2-pentanone are produced as by-products, when the reactor tube is kept at 140 to 200{degree}C at the external wall, diminishing as temperature is increased. There is a temperature differential of 20 to 30{degree}C in the reactor tube between the center axis and external wall. 3 figs.

    This paper reports the result obtained during fiscal 1994 on research on a technology of low temperature deposition of polycrystalline thin films for solar cells. This research used ITO coated glass substrates, on which CdS was accumulated to a thickness of about 100 nm by using the CBD process, and over this deposition a CuInSe2 film was formed at 300{degree}C by using the ion cluster beam (ICB) process. The manufactured solar cells with a glass/ITO/CdS/CuInSe2/Au structure had an efficiency of 2%. In manufacturing a CuGaSe2 thin film by using the ICB process, effects of acceleration voltage relative to cluster beams and ionization current were investigated. It was found that the film morphology, the result of analysis by using X-ray diffraction, and the electric conductivity are sensitive to the ionization current. From these findings, an optimum film forming condition was derived. A CuGaSe2 thin film was manufactured by using the ICB process over a Cds thin film deposited by using the CDB process. Both of the surface morphology and X-ray diffraction patterns of the film did not show a large change, indicating a possibility of manufacturing cells with a reverse structure. Effects of heat treatment on CuInSe2 monocrystals were evaluated by using ESR and FTIR. 6 figs., 1 tab.

In research on amorphous solar cells using ZnO for transparent electrically conductive films, considerations were given on a growth mechanism of a ZnO film using the MOCVD process. It was made clear that the ZnO film grows with Zn(OH)2 working as a film forming species. It was also shown that the larger the ZnO particle size is, the more the solar cell efficiency is improved. Furthermore, theoretical elucidation was made on effects of rear face of an interface on cell characteristics, and experimental discussions were given subsequently. In research on solar cells using hydrogen diluted `i` layers, delta-doped solar cells were fabricated based on basic data obtained in the previous fiscal year, and the hydrogen dilution effect was evaluated from the cell characteristics. When the hydrogen dilution ratio is increased from zero to one, the conversion efficiency has improved from 12.2% to 12.6%. In addition, experiments and discussions were given on solar cells fabricated by using SiH2Cl2. 9 figs.

    The paper outlines results of elementary study on the coal direct-use iron-making process and how to tackle with it in future. In the process coal and iron ores are used directly without prior treatments like coking and briquetting. The process is composed of three elements: smelting reducing furnace, preliminary reduction fluidized bed, gas reforming furnace. Making mathematical models as a means of study of the process, material balance and heat balance are calculated. Operational unit requirements are estimated, changing them in the range of 20-60% of the post combustion based on three fundamental processes each of which is composed of one or a combination of the three elements. The total cost is also trially calculated, estimating fixed cost including installation cost, etc. With no big differences in the iron-melting cost excluding by-products in each process, the cost may be reduced by 5-10% of that in the blast furnace process. The elementary study has continued almost satisfactorily and attained the expected target, though there still remain some problems. In 1990 the study started of a pilot plant with a 500t/day capacity. 12 figs.

    This paper reports the result obtained during fiscal 1994 on research on surface passivation of high-efficiency silicon solar cells. In research on carrier recombination on SiO2/doped silicon interface, measurements were carried out on minority carrier life with respect to p-type silicon substrates with which phosphorus with high and low concentrations are diffused uniformly on the surface and non-uniformly on the back and then oxidized. The measurements were performed for the purpose of evaluating the carrier recombination at p-n junctions. Effective life time of oxidized test samples increased longer than that of prior to the oxidization as a result of effect of surface passivation contributing remarkably. In research on reduction in carrier recombination on SiO2/Si interface by using H radical annealing, experiments were conducted by using a method that uses more active H-atoms. As a result, it was revealed that the reduction effect is recognized at as low temperature as 200{degree}C, and photo-bias effect is also noticeable. Other research activities included analytic research on minority carrier recombination on micro crystalline silicon/crystalline silicon interface, and experimental research on evaluation of minority carrier life of poly-crystalline silicon wafers. 6 figs.

    For development of production technologies suitable for environment, safety and advanced information-oriented society by improving the flexibility of production lines, some new measurement technologies were researched. Problem solution was attempted by combining the in-situ multi-dimensional measurement technology capable of easily obtaining various 3-D information with the non-contact photon measurement technology superior in operability and sensitivity under any environment conditions. This solution requires a compact radiation source with higher brightness and wider spectral range, and a high-sensitive detector. The technology concentrating photon onto minute regions, high-efficiency transmission, and control technology of photon wave front are also necessary. Development and international standardization of a common interface is unavoidable. In addition, its network is essential for advanced use of multimedia,.

    Remaining life assessment technologies for polymeric materials for geothermal power generation and methods for improving their heat resistance are reviewed, and concepts of scale-free technologies for FRP (fiber-reinforced plastic)-sandwiched pipelines for hot water transportation are described. Materials based on PTFE (polytetrafluoroethylene) and NBR (acrylonitrile-butadiene rubber) are chosen for use as DHM (down-hole motor) sealing material and for application to the stator. With PTFE as the matrix, four candidates are prepared, which are additive-free PTFE, and GF/PTFE, GF/CF/PTFE, CF/PTFE, each containing 20w% GF (glass fiber) and/or 20w% CF (carbon fiber). With NBR serving as the matrix, two candidates are prepared, which are NBR-A containing 20w% aramid fiber and NBR-W which is a vulcanized NBR-A. External force, heat, light, and mud are named as the degradation factors, and each factor and some combinations of external force, heat, and light are repeatedly imposed on the materials. During the effort to develop an apparatus for simulating geothermal circumstances in which the factors will affect the materials in complicated ways, a life assessment technique is developed for such polymeric materials. A technology is developed for providing polymeric rubber elastomer with a heat resistant feature. A study is made to replace transportation pipelines for injection wells with FRP sandwiched pipelines. (NEDO)

    Described herein are the results of the FY1994 research program for analysis and evaluation for development of extra-high efficiency silicon solar cells. It is necessary for development of extra-high efficiency Si solar cells to extend as far as possible service life of minority carriers and to develop the evaluation techniques. Noting photoluminescence (PL) observable even with Si, the method of evaluating characteristics of minority carriers, which are not limited in samples, is developed to experimentally determine their service life from transitional response of the PL characteristics. Si has an extremely low quantum effect, because it is an indirect transitional semiconductor, and needs measurement of very high sensitivity. A rapid heat annealing apparatus and others to generate carriers in the infrared and ultraviolet regions are provided in consideration that these are possible means to increase efficiency. These possibilities will be pursued by developing the annealing techniques. 1 fig.

Quantitative analysis and evaluation are made for introduction of intermittent operational mode in the conventional power supply system in which electrolyte units are connected in parallel and for improved performance by bubbles flowing into the line that supplies the electrolyte to the stack, in order to establish the configurations of and operational procedures for the redox flow batteries. The study on development of redox battery compares the Pb-Sn alloy felt collector with carbon fiber, Pb-Sb alloy felt and the lattice for the conventional lead acid battery, in order to optimize the new lead felt battery. As a result, it is found that the Pb-Sn alloy felt collector is better than any other device tested, because of its higher freedom with respect to electrode shape and battery size.

    Described herein are the results of the FY1994 research program for analysis and evaluation for thin substrate polycrystalline solar cells. In order to analyze the structures of the grain boundaries in and interfaces with the cell substrate, and their effects on electrical activity, the photoluminescence (PL) measurement which enables spectroscopic analysis is applied to electromagnetically cast Si crystals. There are good correlations among PL luminous intensity, MBIC output and dislocation density for the grain boundary which contains many strains and serves as the dislocation source, because carriers in such a grain boundary easily disappear to reduce its luminous intensity at the band ends. Concrete scenarios for realizing thin-film silicon solar cells of high efficiency are presented, based on the analysis of the light-contained thin-film silicon solar cells of high output current, made in the previous year on a trial basis. An alumina substrate of high reflectivity is produced by the experiments of combining various devices. It is expected to realize high output current for the thin-film solar cells. 3 figs.

The outdoor exposure tests have been under way for 3 years for fluorescent plates, as part of the research program for development of materials and elementary techniques, and essentially no degradation has been observed by the perylene pigment test. Coupling of the fluorescent concentrator and solar cell units is investigated for the coupling position and method, to theoretically analyze geometrical coupling efficiency, where they are coupled at the bottom faces in consideration of easiness of module fabrication. It is demonstrated that a high coupling efficiency can be realized when the cell is sufficiently wide relative to thickness of the fluorescent plate. The coupling method is experimentally examined using transparent silicon gel. A prototype module having the same size as the commercial module (420mm by 960mm) is made on a trial basis, where a total of nine 20mm-thick cells are cut out of a single-crystalline silicon solar cell, 100mm by 100mm in size, and are connected to concentrators at the bottom faces. It shows 2.3 times increased output by the test using a large-area solar simulator. 2 figs.

    An evaluation test was conducted on SWD (Seismic While Drilling) method as a part of the investigation of geothermal development and promotion. The test was implemented at the time of drilling of N11-MD-3 well in the northeast base area of Busadake, Hokkaido. The test items were such as verification of direct waves propagating from a bit to the surface, identification of signals passing through a fault zone using direct waves and reflected waves, estimation of distance between a fault and a bent zone, and grasping the direction of signal propagation at the time of inclined drilling. As a result of the experiments and studies, following conclusions were obtained. Reflected waves extracted are not necessarily limited to those from a reflection area from which the shape of a fault can be grasped; unless there is a clear reflection area that can be picked up on the surface near a fault, the application of this method is not effective. In an analysis using direct waves, it was possible to obtain an inclined angle of a fault plane from the estimation of velocity structure, propagation route, and assumption of the shape of the fault plane and, therefore, to grasp the shape of the fault. Obtaining reference data is essential for identifying bit signals. (NEDO)

    The paper studied a solar heating system with thermal core type soil heat storage (combining a thermal core composing of a water tank and an underground pebble tank and the soil around the heat storage tank and also using solar energy). Solar energy is stored by temperature level in the high temperature water tank, the low temperature pebble heat storage tank and the soil around the heat storage tank. Heat is recovered according to temperature as direct ventilation space heating (utilization of pebble tank air), floor heating (utilization of hot water of the heat storage water tank) and heat pump heat source (utilization of pebble tank air). A study was made of performance and regional effectiveness of the system under different weather conditions. A study was also made of effects of the water tank for short term heat storage by changing the water volume. Using the same structure, etc. for the system, the system was evaluated using weather data of Sapporo, Tokyo and Kagoshima. In terms of efficiency of the system, the system structure was found to be most suitable for weather conditions in Tokyo. However, the air heat source heat pump which cannot be usually used in the cold area has come to be used. Such effect except efficiency is also considered, and the amount of performance to be targeted in each region changes. 2 refs., 14 figs., 1 tab.

    This paper describes a method for evaluating grouting that is a means for improving the ground for excavation for building underground structures in urban areas. This is an effort for improving reliability, and evaluates the rate of filling of the water glass base chemical liquid injected for improving the ground utilizing the fact that this liquid is higher in conductivity than the soil or ground water. An experiment was conducted using a model ground so as to define the limit of applicability of this resistivity tomography by studying electrode arrangements and difference in resistivity between the grouted liquid and ground water. It was then found that the liquid-injected region is evaluated more accurately when the measuring electrodes are installed nearer to the region, that evaluation is satisfactorily accomplished when the region spans not less than 75% of the distance between the electrodes, that higher accuracy is expected when the difference in resistivity is greater between the grouted liquid and ground water, that evaluation is satisfactorily accomplished when the resistivity of the grouted liquid is not more than 10% of that of ground water, and that any grouting liquid usable for ground improvement in civil engineering in urban areas can be applied to any other grounds except where there is influence of seawater. 31 refs., 55 figs., 8 tabs.

    In connection with the innovative manufacturing of large base materials having a mesoscopic grain structure by means of technologies for high deformation accumulation control, recovery/recrystallization control, etc., research was conducted on evaluation technology for various characteristics such as formability, with fiscal 2000 results compiled. For the purpose of evaluating average grain size from an optical microscopic photograph of structures, it was judged reasonable to determine the average cut piece length. A device introduced to this development project was a horizontal goniometer capable of ODF (crystallite orientation distribution function)/pole figure measurement, qualitative analysis, and residual stress measurement. With warm rolling performed by controlling both material temperature of 7475 based alloys and roll temperature, thermally stable micro sub-grain structures were obtained. As a result of ODF analysis of this warm-rolled material, it was found that a {beta} orientation group existed very sharply in the area from the sheet surface to the center planar part of the thickness. The grain refinement of 5083 based alloys using a warm rolling method was also successful, with its ODF analysis revealing that the accumulation of the {beta} orientation group was very high as in the 7475 based warm-rolled materials.

    This paper evaluates influences of stacking of incident angles against the reflecting surface on the resolution. Basic equations for evaluating the influences were deduced. A simple evaluation method has been provided using these equations. The present evaluation method is considered to be useful for acquisition design, processing, and interpretation of data as an indicator. According to the equations introduced in this study, there are some demerits for stacking traces whose incident angles were large. A total reflection region often appears due to the decreased resolution, and the vertical resolution decreases prior to stacking. Occasionally, it is not effective to remove traces having large incident angles from the viewpoint of resolution. In practice, the selection of most suitable trace through trial and error is not easy due to difference in individual regions. An evaluation method must be discussed, by which the optimal trace can be selected automatically during the data processing. 6 refs., 15 figs.

    It is recently, that is, in and after the 1980s that socio-scientific approaches began to be made to studies on `risk`. It started to be made clear that the progress of the scientific technology does not necessarily bring about good news to man, and obvious estrangement has begun to appear between scientific evaluation and social evaluation of risk. The subject of risk communication (RC) study is to tackle a proposition whether the estrangement will continue to exist as estrangement or the estrangement can be made smaller by any means. This paper explains the recent trend of the study. For example, as for how each individual thinks about risk, that is, the risk perception, a new framework is trially being constructed by introduction of the quantitative method using psychometrics. A duty of RC is to serve to bridge the gap between scientific technology and society which are controlled by values which are incompatible with each other. Therefore, RC will be more and more important. 15 refs., 1 fig., 2 tabs.

    In the conversion from solar energy into chemical energy (fuels) by photochemical conversion, an electron donor is necessary since all the fuels are reductive compounds. From the viewpoint of economic profit, water is the only one candidate as a cheap compound and existing impartially. In this paper, photosynthesis as well as the realization of its artificial model, and the relevant basic research executed recently aiming at the construction of an artificial photosynthetic system are explained. The main reaction of photosynthesis is the generation of carbohydrates by the reduction reaction of carbon dioxide with water as an electron donor and solar visual light as an energy resource. As a special example thereof, the UV photolysis of water due to the photocatalysis of a micro-particle system is introduced. The method of using a semiconductor and the method of using sensitizes are described as the photo excitation system when designing the artificial model. Additionally, as the research with respect to the construction of an artificial photosynthetic system, a photo-exciting charge transfer system is introduced. 27 refs., 1 fig.

    As measures for the spots difficult in metering within a framework to integrally automate the power distribution, a remote reading system was prototypically tested and evaluated in reliability on the actual field. The system methodically selected the signal {prime}s line injection, high frequency wave signal and voltage detection, while the signal frequency, transmission rate and highest transmission output were set at approx. 3.5KHz, 7.5bps and 50dBm, respectively from the test result. The demonstration test on reliability of the system locatively selected a vicinity of high voltage consumer, high harmonic wave-generating consumer, transforming station, etc. The total ratio of success in reception was comparatively high in Kuzuno and Yamazaki areas, but low in Kamojyo and Ichinomiya areas, The badness in reception was caused by the fluctuation in noise and strongness in damping which was influenced by the condenser in the high voltage consumer. The locative relation between the parent and child stations of system, and high voltage consumer being classified into four patters, an application table of remote reading system was prepared by simulation. 14 figs., 6 tabs.

    Study of metamorphic belts and tectonics is introduced. Minerals supposedly originating in the transitional zone and the lower mantle, that is, inclusions in diamond in kimberlite, are deemed to carry information about the depth level of 670km and lower. The place of origin of peridotite, Alpe Arami of Switzerland, is again estimated at a level of 300km or deeper. In the tectonic cross section in this region, the oceanic crust is bent and folded, and such a structure enables the supposition that fragments off the transitional zone may be carried upward to the ground surface. This region is now being limelighted, with plume tectonics enjoying popularity. The split of Pangaea is related with the ascent of plume. In the eastern part of Australia, there are alkali rocks attributable to the plume that was supposedly active at the end of the Proterozoic. Zircon U-Pb dating by SHRIMP offers a new approach to the tectonics of metamorphic rocks, and is reinforcing the position of metamorphic petrology relative to the study of collision and split of continents. 64 refs., 10 figs.

    This paper describes an automatic trespassing supervisory system with ITV and picture processing (PP). The paper details an integrated control system and automatic supervision. The system functions to automatically detect a trespassing by means of PP, transfers items of information collected by sensors to a remote control center, and records relevant data. The operation principle consists of measurement of change in two or more images of moving bodies with binary value at a certain interval, determination on acceptability of the moving bodies represented by human characteristics, and identification of a trespasser. The system consists of an automatic supervisory device using PP and an automatic patrolling and searching device by means of sensor measurements. The supervisory device has images outputted from ITV and VTR processed by PP, host computer, and HD, and linked to an indication mechanism. According to the result of a site test at wireless transmission station of Kyushu Electric Power Company, the difference between measurement values collected by the searching device and those by the supervisory device was [plus minus]3% or less (other than EG output current), which is a useful value for verification. Although the basic technique has been established, practical use of the system still has some problems including performance improvement in picture processing. 37 refs., 38 figs., 18 tabs.

    Some sulfides containing silver show high ion mobility based on movability of silver, whose application is expected. Studies have been carried out centrally on synthesis of new compounds of ternary silver sulfides by elucidating the relationship among their compositions, structures and properties by means of crystal chemical studies mainly on their phase relationship. A few new compounds have been synthesized, such as the ones having the argyrodite family compound structure including transition metals. The synthesizing process takes a kind of turbulent liquid state structure at elevated temperatures because of movability of silver, but silver is fixed at low temperatures in different sites between skeleton structures made by other atoms. These studies on phase transfer, structures, and silver movability have been based on X-ray diffraction, infrared and Raman spectroscopic measurements, NMR, measurements of electric and thermal characteristics. For the studies related to compositions and structures of ternary metal sulfides which take compound crystalline structure, a structure analyzing method based on multi-dimensional hyperspatial groups was used. This paper reports the summary of the studies in seven chapters, and dwells on the remaining problems and future prospects. 158 refs., 114 figs., 65 tabs.

    The water tank test of marine structures or submarine structures uses a wave maker to generate waves. A typical flap wave maker uses the wave making flap penetrating a water surface whose bottom is fixed on a tank bottom through a hinge, and the top is connected with a rod driven by rotating servomotor for reciprocating motion of the flap. However, this driving gear using a rotating servomotor and a bowl- screw has some defects such as noise caused by bowl rotation, backlash due to wear and limited driving speed. A linear motor with less friction mechanisms was thus applied to the driving gear. The performance test result of the prototype driving gear using a linear motor showed the possibility of the linear driven wave maker. The linear driven wave maker could also achieve low noise and simple mechanism. The sufficient durability and applicability of the linear driven wave maker mechanism were confirmed through strength calculation necessary for improving the prototype wave maker. 1 ref., 5 figs., 2 tabs.

    This paper describes course of pneumatic technologies and problems in future researches. Pneumatic systems are inferior to electric and hydraulic systems in terms of efficiency. It is because electric power is converted into fluidized energy by using a compressor, and then converted to mechanical energy by using an actuator. When theses published from 1990 through 1999 are put in order, the research objects are accounted for half by control related technologies, and researches related to elements account for only one third. This paper enumerates assignments to be tackled positively in the future by utilizing compressibility of air in pneumatic systems, and features of high speed drive utilizing the stored energy instantaneously. Application of air pressure to robotics from the demand of the aging society, and pneumatic tools having intelligent functions must be subjected to new contrivances. These will serve for work assistance systems to enable aged people to perform works, and for activating industries including organic agriculture. Tools in this sense may include impact wrench, and others. Furthermore, development of fundamental studies for 'why air pressure?' is demanded strongly, including the viewpoint of LCA in the recycling type society. (NEDO)

    The Research Group on Earthquake Ground Motion in Sapporo City established in May 1996 has inaugurated collection of information on ground structures and observations of strong earthquakes in Sapporo City. The Research Group on Earthquake Ground Motion in Sapporo City has carried out geological investigations, electric logging and PS logging to date in three boring holes each with a depth of about 100 m, 200 m and 600 m. According to the result of the logging in the new Ishikari Bay port (600-m deep hole), the S-wave velocity has increased slowly as it starts from the ground surface to greater depths, but showed no noticeable velocity boundaries in this range of the depth. The Sapporo municipal office has drilled three observation wells (500-m deep) for the purpose of determining focal points of microtremors directly under the city area. Hole-bottom observation has been inaugurated since the beginning of this year. According to comparison of the results of loggings at great depths, a depth at which the S-wave velocity reaches about 700 m/s becomes greater toward the sea area. The result of calculations on amplification characteristics of the SH wave on rock beds revealed that a seismic wave of about 0.5 Hz is amplified by a little more than two times. 1 ref., 5 figs., 1 tab.

    Kinds of ground materials, porosity, electrical resistivity of pores, degree of saturation, and content of clays are the factors affecting the electrical resistivity of soils. In addition to these factors, the electrical resistivity of soils around hot spring water and geothermal areas depends on the temperature due to fluctuation of cation mobility in the pore water with the temperature. In this paper, the temperature dependency of electrical resistivity of groundwater and soils is investigated by recognizing that of groundwater as that of pore water. As a result, it was found that the electrical resistivity of groundwater becomes lower as increasing the amount of dissolved cation, and that the temperature dependency of electrical resistivity is not significant because of the small mobility of cation. The electrical resistivity of soils was significantly affected by that of pore water, in which the mobility of cation was changed with temperature changes. Accordingly, the temperature dependency of electrical resistivity of soils has a similar tendency as that of groundwater. 5 refs., 9 figs., 2 tabs.

    In order to demonstrate the power transmission using microwave and arrange advantages and problems in the wireless power transmission, field tests of point-to-point power transmission were conducted. Microwave frequency of 2.45 GHz was used, which is assigned as the industrial, scientific and medical frequency. The transmission system is composed of generator, director tube, primary radiator, and transmission antenna. The maximum 5 kW of microwave power can be transmitted by combining a 3 m-diameter parabolic antenna and a magnetron. The receiving system is composed of devices called as RECTENNA (rectifying antenna). A large capacity and high efficiency RECTENNA was developed, by which the maximum 2.5 W of input power per single device can be provided. As a result of the experiments, efficiency at the transmission side was over 70%, and RF-DC efficiency at the receiving side was about 51%. At the open-air test site, however, the total efficiency of only 14.8% could be obtained. 8 refs., 12 figs.

    This paper described the researched results of the demonstrator of a turbofan engine for supersonic aircraft (IHI-17). A turbofan engine with an afterburner was experimentally fabricated and various engine tests have been carried out since 1988. Although the engine size is small, the fighter engine specifications were applied to its design and the prior or simultaneous research on each component was carried out. As a result, the system integration technique by which an engine was assembled by integrating each component could be established. New materials and new manufacturing techniques such as turbine blades of single crystal, turbine disks of powder metallurgy and deep chemical milling for a duct were developed to use for the long term engine test and the prospect to commercialization could be obtained. The following techniques have been established and the results satisfying target specifications could be achieved: the three dimensional aerodynamic design of compressor and turbine, the adoption of air blast fuel atomizer to suppress the smoke generation, an afterburner of spray bar system and the mounting type FADEC (full authority digital electronic control) to control the engine with the afterburner. 4 refs., 15 figs., 4 tabs.

    The noncontact measurement method of rotating blade vibrations was developed for fans, compressors and turbines, and applied to turbofan engines and industrial gas turbines. The method required no machining of blades and rotor except sensors attached to a casing to detect blade-tips. The method allowed to measure simultaneously the vibration of all blades, by measuring elapsed times of blade-tips rotating from a measuring start point to a detecting point, and detecting the time differences between a vibration and non-vibration condition. The measuring system was composed of the detectors and subsystems for signal processing, control, calculation and display. The vibration wave forms of a few blades and the maximum vibration amplitudes of all the blades were displayed on a realtime basis in an on-line monitoring mode, and an off-line data processing mode was also available for subsequent analyses and reviews. The results of application to existing engines favorably agreed with those of strain gage measurements. 16 refs., 75 figs., 3 tabs.

    This paper explains concepts of aircraft engine afterburner, and describes history of afterburner study, and describe the result of major research items. An afterburner is located down stream of a fan, compressor, burner, and turbine in a jet engine. Its basic principle is that fuel is injected into turbine exhaust and fan air flows from an fuel injector, ignited by a spark plug using oxygen remaining in the exhaust gas flow, burned and flame-held by a flame stabilizer. The combustion gas of high temperature (1,700 to 1,800 {degree}c) thus generated is jetted out from an exhaust nozzle to increase the thrust. The prototype afterburner is featured by adoption of a mixed type fuel injection system that provides wide stable combustion range, and flame stabilizer with a scoop aimed at improving the ignition performance and combustion efficiency. A confirmation test verified smooth ignition and wide air to fuel ratio for stabilized combustion. 4 refs., 16 figs.

    This is the report No. 98 issued by the Inorganic Material Research Institute. An intelligent material is a substance and/or material which responds intelligently to environmental conditions and exhibits functions. One of the features of amorphous materials including amorphous glass is a large freedom in chemical composition. These materials maintain order in short distance, but have as a whole the turbulent and specific atom orientation. Therefore, high tolerability in selecting the composition, and diverse synthesizing methods are available. A wide range of utilization may be conceived, such as introduction of the state of electrons having different valences in a structure, and the diverse chemical combinations. Patterns of existence of polyhedrons having different orientations, and how they are connected correlate closely with an external environment. Intelligent materials have high freedom against change in the external environment and are suitable to exhibit intelligent functions. Setting heat and light as the external conditions, attempts have been made on search and creation of intelligent materials based on state change induced by interactions between the two factors. Fundamental studies have been made on synthesis of different environment responding glasses and films, and on factors and phenomena for exhibition of the intelligence. 62 refs., 91 figs., 8 tabs.

    This is No.92 report of National Institute for Research in Inorganic Materials, concerning search of unknown materials. Purposes of this study are to construct new chemical bond and reaction theory, to systematize the existing compounds, and to search and create the unknown materials, systematically. Structure prediction of electronic state was investigated by means of molecular dynamic method, to determine the electronic state and structure of multi-systems. For the magnetic semiconductors, interactions were investigated between the magnetic spin and electron or hole which is a carrier. The in-solid bond theory aims at clarifying the bond state of materials in which transition metal compounds and inter-electronic interactions are significant. Prediction of the electronic structure of unknown materials can suggest the design of new materials. In the fields of synthesis, design and synthesis of new inorganic ion exchanger and ionic conductor are investigated using Bi oxides and its related materials. There are a lot of compounds having various crystal forms for rare earth element oxides and transition metal oxides. To establish the system of material design, thermodynamics, phase equilibrium diagram, crystal structure, and physical properties of new materials were discussed. 168 refs., 127 figs., 44 tabs.

    Studies are conducted to promote energy-saving in construction works as part of environment protection programs. The first phase is for survey and analysis works for energy-saving in the current building design and construction works, and for processes, procedures and materials in model works (construction of sub-stations). The second phase is for studying energy-saving designs, materials and procedures, which are applied to model works, to assess their energy-saving effects , costs and applicability. The horizontally developed samples are prepared for the future development, based on the `continuous improvement of environment-management systems by establishing the PDCA cycles,` which is one of the basic requirements of the ISO14001 (environment management system). These efforts have reduced CO2 emissions associated with the manufacture of construction materials by 20%, mixed wastes by 45%, and plywood frame requirement by 70%. It is also confirmed that they can be realized at only around 3% higher cost. 9 refs., 10 figs., 3 tabs.

    Discussed herein are mooring performance requirements of the new types of marine structures now proposed, and characteristic ranges and future expansion potential of the existing mooring systems. The mooring systems studied for floating structures are catenary, single point (multi-leg and single-leg types), fixed structure with fender and tension leg mooring systems. The studied items include extraction of the elements that constitute rigidity of the spring for horizontal mooring, survey on and data collection for each element, determination of element ranges, programs for mooring analysis, assessment of mooring characteristic ranges, and potential development of the characteristic ranges. It is concluded that the existing systems with their current characteristic ranges and future possibility are insufficient for the future marine structures. It is therefore necessary to develop new mooring concepts, instead of expanding the current concepts, in order to meet the mooring performance requirements for the new marine structures. 14 refs., 9 figs., 11 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.

    This paper proposes a non-powered heat transportation (HT) system. The system is composed of an evaporator, condenser, receiver, switching chamber (SC) and 3 check valves which are connected with each other by vapor and liquid tubes. Condensed liquid supercooled in the condenser exists in the receiver forming a saturated condition at a concerned temperature, and condensed liquid is lifted up from the condenser to the receiver by pressure difference between the evaporator and receiver. Generally evaporation pressure is higher by pressure difference between liquid levels in the condenser and receiver. The lifted up amount of condensed liquid increases with evaporation pressure, resulting in an increase in heating surface area of the condenser and amount of condensed liquid. A proper evaporator pressure is thus retained by reduction of evaporation pressure. SC is connected with the receiver and evaporator, and switches high- and low-pressure valves by motion of an inner float to transport heat from the evaporator to condenser. Reverse HT is possible as normal latent HT by installing a bypass. Some problems are also described. 2 refs., 8 figs.

    The effects of pitching and heaving motions of an aerofoil on accretion of ice thereon are investigated for the design of wind turbine blades. The conditions under which an aerofoil shows a heaving motion are 10m/s as wind velocity, -12degC as ambient temperature, 0.5Hz as frequency and 5mm as amplitude. Initial growth of ice is stochastic to a great extent; ice grows rapidly around the seed which is formed by chance somewhere on an laerofoil. The effects of ice appear in the flow field in the vicinity of the aerofoil front edge, as it continues to grow, providing different conditions for water droplets to collide with each other. Average ice shapes can be classified by environment, although at low repeatability. Range of ice accretion varies depending on aerofoil motion, whether it is pitching, heaving or at rest. The most important factor that determines behavior of ice accretion is conditions of the flow field near the aerofoil front edge. In a pitching or heaving motion, its speed is an important factor for growth of ice. 2 refs., 5 figs.

    The interaction force induced to hull by steering is important for prediction of control performance of ships. The control interaction force coefficient dependent on the steering has been investigated through the rudder angle tests using three small model ships with a length of 2.5 m, i.e., mathematical type of ship, cargo type of ship, and tanker type of ship. The interaction forces acting on the hull, propeller, and rudder were determined by measuring the lateral force as well as the forward force of the hydrodynamic forces acting on the rudder. These forces were compared with the theoretically calculated values. Prior to the rudder angle tests, the self propulsion factor and the number of revolution of propeller were determined from the results of the open water tests, resistance tests, and self propulsion tests by the changing load method. The rudder angle tests were conducted under this number of revolution of propeller as a standard condition, and under those increasing and decreasing by 15%. Consequently, the interaction forces determined from the rudder angle tests agreed well with those determined from the other tests. When comparing the control hydrodynamic forces determined from the tests with those theoretically calculated, a similar trend was observed. Effectiveness of the theoretical model was confirmed. 4 refs., 14 figs., 3 tabs.

    This study is being progressed during a period from 1992 to 1999 as part of the NEDO`s clean coal technology program. This paper describes what has been discussed to date. The absorption method and the adsorption method may be used to recover CO2 as means to deal with the problem of global warming resulted from burning coals. These methods, however, have problems in economy caused from concentration of CO2 in flue gas being low. The present study is intended to raise the CO2 concentration in flue gas by using oxygen plus circulated flue gas in the place of combustion air, so that CO2 may be recovered as it is without being separated from the flue gas. Therefore, an oxygen-blown pulverized coal fired power generation plant having a cryogenic oxygen manufacturing equipment was designed to discuss the plant operability and economy, and the pulverized coal combustion technology by using a dynamic simulation. A large number of findings have been obtained already, and the study has reached a level at which grasping the whole image is now possible. 13 figs.

    In order to grasp the phenomena actually occurring in the combustion chamber for improving the combustion and for reducing the exhaust gas emission of the diesel engines, the visualization techniques are becoming to be essential and indispensable. The authors have observed the spray and combustion, when proceeding the combustion improvement by the high pressure injection, and then have performed the image processing and simulation calculation based on them. The high pressure injection devices used for the experiment are the intensifier type and accumulator type which can generate the injection pressure more than 200MPa, and both of them are the electronic controlled hydraulic drive type, and are driven separately from the engine. Since it was found that the analysis of high pressure injection by the hologram is limited in the conditions, as for the spray, the spray analysis was performed by the transmitted light attenuation method and laser sheet method. As for the combustion, the engine for observing the combustion was trially made, and then the combustion state was observed by the high speed photograph. Furthermore, the flame temperature analysis by the image processing using the combustion photograph and the analysis of flow and turbulence of the flame were carried out. 9 refs., 16 figs.

    This paper describes odor in automotive cabin. Odor of new cars is rapidly disappeared during the use. This is greatly due to the adaptation of olfaction. The generation of odor is also decreased. It was found that aliphatic and aromatic hydrocarbons were rapidly disappeared. Decrements of oxygen containing and sulfur compounds were low. For amines, high boiling amines increased after three months. The odor component from crews was derived from the exhalation. Trimethylamine, methyl sulfide as well as iso-prene were detected. They could be derived from tobacco smoke, perfume and hair conditioner. Exhaust gas of diesel vehicle going ahead is one of unpleasant odors from the running atmosphere. A correlation coefficient 0.77 was obtained between the stimulation and aldehyde/ketone. A correlation equation was deduced using stimulation, discomfort degree and odor characteristics as object variables and using logarithms of trace analysis values as explanation variables. There are still a lot of unknown issues concerning combined odors. 9 refs., 9 figs., 1 tab.

    Harmonized molecular materials (HMM) were researched to create functional materials adaptable to needs such as environmental harmony and high-efficient conversion in post-industrial society and aging society. Superior mechanisms function efficiently in organisms for perception, transmission and processing of information, and transport and conversion of substances. These functions are caused by harmonization between organic molecules, or organic molecule and metal or inorganic substance. HMM is a key substance to realize these functions similar to those of organisms artificially. It is the purpose of this research to develop HMMs, reform production process by innovating separation and conversion technologies, and finally realize molecular chemical plants. This research also develops high-efficient devices to contribute to the information society, and progresses the industry of bio-functional materials such as high-sensitive bio-sensor. The functions, applications and creation technologies of three kinds of HMM such as assembly, mesophase and microporous materials were researched in fiscal 1995. 956 refs., 128 figs., 13 tabs.

    In Japan, there were some serious disasters in recent years. In 1991, Unzen-Fugendake erupted and more than 1,000 people were forced to take refuge from their houses. In 1993, Hokkaido-Nanseioki earthquake attacked the south-east area of Hokkaido and more than 3,557 houses were destroyed. In Japan, the government supplies the temporary housing to those who lost house from the natural disasters. The purpose of supplying temporary houses mentioned in the disaster relief law (established in 1947) prescribes the purpose of temporary housing that to rescue the poor who can not afford getting a shelter with their own funds. But actual condition of temporary housing is completely different. Government supplies temporary housing to all those who request temporary housing. The term of using temporary house tend to become longer. The regulation about temporary housing has not been yet up to dated. Many problems concerning about temporary housing originate in outdated regulation. The temporary housing have to be ranked in the part of restoration process from natural disaster. (author)

    The energy saving environment-friendly technology for low- grade difficult-to-process ores was researched focusing attention on the hydro-metallurgical process of non-ferrous metals. This research aims at development of both effective leaching system of metals, and separation/crystallization system recognizing the property difference between metal ions in solution. The leaching system allows the inexpensive molecular level control of electron transfer, mass transfer of metal ions and stabilization of leached metal ions in a solid/liquid interface. The system thus allows selective leaching of metals from various resources such as difficult- to-leach sulfide minerals to prepare concentrated solutions. The separation system can obtain high-purity solutions including each metal ion by advanced separation/concentration technology from the solutions. The crystallization technology (including electrolysis) is developed for preparing target metal materials by molecular level control of nucleation, particle growth, thin film formation and bulky metal formation processes. Overall energy consumption is reduced to 1/3 of that of the pyro-metallurgical method, aiming at zero emission. 15 refs., 14 figs., 11 tabs.

The smart structural system is a structural system which incorporates functions of perception, judgment and learning by integrating functions, structures and information, to ensure the structural soundness at real time and control the active-adaptive of shapes. The final goal of it is to make materials and structures similar to organic systems. It has a self-repair function which can detect the generation and propagation of cracks and prevent the destruction positively with conducting self-diagnosis. High performance, high efficiency and energy saving are expected by combining the conversion of design concept into destruction control and the regulation of vibration, noise and shape. Especially, it is effective for the safety of aerospace systems, earthquake disaster measures, and extension of machine life. This report describes the background, purpose, R and D activities in Japan and foreign countries, and basic development themes. In addition, it arranges the needs of various industrial fields systematically, and proposes a concrete concept. Furthermore, the effects expected by the application of smart structural systems and the outline of international technical cooperation are presented. 110 refs., 164 figs., 19 tabs.

For the high temperature heat storage type (utilizing hydration reactions), a 25 Mcal-scale pilot partial test unit is operated, to study applicability of the practical materials and other operation-related themes. For the low temperature heat storage type (utilizing hydration reactions by solute mixing), a pilot system is operated, to attain heat recovery of 75% or more, heat storage density of 30 kcal/kg or more, and output temperature of 7 degrees C. For the low temperature heat storage type (utilizing clathrates), the evaluation tests by a pilot plant produce heat recovery of 93.2% and heat storage density of 32.0 kcal/kg. In addition, the R and D efforts are directed to, e.g., researches on plant simulation techniques and combined systems. (NEDO)

    This paper reports the result obtained during fiscal 1994 on a demonstration research on photovoltaic power generating systems. Solar cells with an output of 750 kW, storage battery facilities with an output of 3,058 kWh, three DC-AC converters with a rating of 250 kW, and a diesel generator with an output of 300 kW having been installed up to the previous fiscal year were combined to perform comprehensive adjustments and tests such as battery charge/discharge tests and AC parallel operation tests. The battery charge/discharge tests revealed that the 10 hour rate discharge capacity meets the specifications, and the batteries are free of deterioration after a demonstration operation of about 4.5 months. Difference between the power generation record and the planned value is thought due to the following reasons: the array output data in a power line connected system come about 90% of the simulation result due to correction coefficient for the solar cell conversion efficiency; the inclined face insolation results in less by about 7% than the planned value, and the transmittable power amount less by about 14% in total; the load power amount is less by about 7% than the planned value; and the balance supplementing power factor increases by about 4%. 5 figs., 2 tabs.

    Computer chemistry was investigationally studied. The advance of theoretical chemistry is indispensable to the design of materials, and the theory and high speed computational method are expected which can simulate the real system with more accuracy. It is basic to simulate structures and physical properties of structural molecules and the aggregate, but the meso region, the intermedium region between structural molecules and the aggregate, has became regarded as important. Rough visualization models in high polymer materials and the progress of computational software/hardware of quantum chemistry/molecular dynamics such as catalyst become necessary. Seamless zooming is proposed as a concept of the software which simulates materials from micro/macro/meso viewpoints. Moreover, to make the most of computer chemistry, an integrated system is necessary which generally handles computational software, database, etc. For the development of software, indispensable is the demonstrative verification by a combination of experiments and researchers. Under a commission from NEDO, the investigational research was conducted as a leading study during fiscal 1996 and 1997 to view the course of the research. 17 refs., 37 figs., 5 tabs.

    Disaster caused by liquefaction is an important problem for the development of water-front because most of the places suffered from liquefaction disasters recently are located on sandy grounds. The damaged cases in the past due to liquefaction induced by earthquakes are grouped into: subsidence and inclination caused by the loss of supporting force of the ground, coming to the surface of buried structures due to excess pore hydrostatic pressure, destruction of lifeline accompanying the fluidization of ground, breakdown of bulkhead, retaining wall, etc. by increased earth pressure, sinking of soil structures, ground fissure, sliding, and immersion in floods and submergence of farms due to spouting of underground water. As regards prediction of liquefaction, description is made on the prediction of the occurrence of liquefaction and liquefaction prediction for which sedimentation environment is taken into consideration. Open-cut investigation can be said as the most effective means for accurate learning of the depth, thickness and sedimentation structure of liquefied layers. Liquefaction layers found in remains are also introduced. 16 refs., 6 figs.

    My efforts towards at the development of aeroengines since the end of the war are described. The J3-7 engine propelled the T1 trainer plane, and was installed as booster aboard the P2J antisubmarine patrol aircraft. It was the first jet engine that Japan produced after the end of the war, and had been in use until quite recently. I took part in the construction of a prototype of the JR100 series designed to serve as VTOL (vertical take-off and landing) aircraft lift engines, and in the test thereof. As the shift from turbojet to turbofan proceeded, I participated in the development of the FJR710 engine under the guidance of National Aerospace Laboratory, and the product was installed aboard an experimental STOL (short take-off and landing) aircraft Asuka. I next joined a Defense Agency initiative for a reheat turbofan to replace the J3 aboard trainer plane, and the result was the low bypass ratio/high output F3 engine. In 1989, Ministry of International Trade and Industry decided for a large-scale project of developing an engine for a next-generation supersonic transport, and the HYPR (Super/Hypersonic Transport Propulsion System) project was started. The project was participated in by manufacturers from overseas, which were GE, P and W, RR, and SNECMA. The foreign corporations worked on an equal footing with the Japanese parties, and collaboration between the participants was smooth, with each party endeavoring in the field they were good at. The project will be concluded as scheduled in fiscal 1998. (NEDO)

    In this paper, recent investigations and researches on pollinosis are summarized as centering on the investigation entrusted by the Ministry of Health and Welfare and executed since 1992, and especially the surveys on Japanese cedar pollinosis during 1995 to 1996. The quantity of pollen surveyed in 1995 is the greatest in the survey history of nationwide flying pollen. Particularly, the quantity of cedar and hinoki pollen is 10 to 40 times as many as that in the year before. Consequently, since the sensitization and onset due to the cedar pollen increased greatly, the objects of the surveys and the researches were mainly in respect to the analysis of onset factors of pollinosis, clarification of its natural process, evaluation on the effectiveness of desensitization therapy, the clinical subjects including the confirmation of pharynx symptom and asthma symptom, and the discovery of naturally sensitizing dog. A fact that the quantity of flying pollen concerns the occurrence and degree of the clinical symptom has already been indicated by a clinical observation carried out for a long period of time. In respect to specific prophylaxis and therapy, for the first time the pollen masks and glasses sold on the market are investigated, and the necessity of the verification thereof is described. 27 refs., 7 figs., 5 tabs.

    The adsorption of acetaldehyde by porous ceramics impregnated with hydrazinium aluminum sulfate (HAS) is studied. Silicagel, activated alumina, activated clay, and activated carbon are compared, and it is found that silicagel and activated clay are suitable as a substrate for HAS impregnated adsorbent. The adsorption mechanism of acetaldehyde by the adsorbent is believed to be one in which acetaldehyde reacts with hydrazinium and yields acetaldazine. The adsorption capacity of the adsorbent at low acetaldehyde concentration of 0.1 ppm was as large as 1.36 mol/kg. This adsorption capacity at 0.1 ppm acetaldehyde concentration is remarkably larger than that of conventional activated carbon. Hydrazinium decomposes easily in the air because it is a strong reducing agent and reacts with oxygen or carbon dioxide. But hydrazinium impregnated on porous ceramics with HAS becomes more stable and maintains reactivity with acetaldehyde for longer than six months. An adsorbent made of porous ceramics impregnated with HAS is useful as a deodorant for acetaldehyde. 8 refs., 6 figs., 6 tabs.

    Validation researches have begun about the interrelationship between systems and human beings using a virtual-reality plant environment. This article introduces some recent studies about the human interface in an operation control system in a virtual-reality environment. The evaluation of a system from the viewpoint of ease of use is called a usability test, to which a psychological protocol analysis is applied for finding out problematic points by carefully observing the operator actually operating the system. For instance, in a boiler plant simulator constructed for DCS training, the operator is given some tasks, such as the prediction as to how a certain event will develop, probing of the cause of anomalies, and execution of related operations. Video cameras are installed at various spots for the minute observation of facial expressions and behavior of the operator, and the operator`s recognition, thought, behavior, and utterances, expressed by the operator facially or verbally, are recorded and analyzed, and the results are utilized for system improvement and operator training. 3 refs., 2 figs.

    This paper summarizes study trends mainly in CO2 fixing processes. Underground CO2 storage is a most promising method because it can fix a huge amount of CO2 and has low effects on ecological systems. Storing CO2 in ocean includes such methods as storing it in deep oceans; storing it in deep ocean beds; dissolving it into sea water; neutralizing it with calcium carbonates; and precipitating it as dry ice. Japan, disposing CO2 in these ways, may create international problems. Separation of CO2 may use a chemical absorption process as a superior method. Other processes discussed include a physical adsorption method and a membrane separation method. A useful method for CO2 fixation using marine organisms is fixation using coral reefs. This process will require an overall study including circulation of phosphorus and nitrogen. Marine organisms may include planktons and algae. CO2 fixation using land plants may be able to fix one trillion and 8 hundred billion tons of CO2 as converted to carbon. This process would require forest protection, prevention of desertification, and tree planting. Discussions are being given also on improving power generation cycles, recovering CO2 from automotive exhausts, and backfilling carbons into ground by means of photosynthesis. 23 refs., 7 figs., 1 tab.

    Researches have been made to increase density of 200,000-kW class generator and to increase capacity of 600,000-kW class generator necessary for putting superconducting generator into practical use. This paper summarizes the achievements in fiscal 2000. In the study of increasing densities of superconductors and field windings, strands were fabricated, in which aging heat treatment conditions, number of aging, and processing degrees between each aging were varied, to increase the critical current of Nb-Ti strand, wherein as high critical current as corresponding to about 90% of the target was obtained. Possibility of increasing the critical current with the final processing degree in the range of 4 to 5 was verified from the relationship between the final processing degree and the critical current. In the study of increasing capacities of superconductors and field windings, findings were acquired on enhancement of conductor stability and reduction in AC loss, with regard to superconductor strands well balanced in the two elements. Prospects were obtained in achieving the AC loss of 200 kW/m{sup 3} in the targeted superconductor.

    Gas hydrate is a clathrate compound in a gaseous molecule as the host, stable under relatively mild environments. It is deposited in the 600m or deeper sea bottoms to form the gas hydrate deposit and massively occurring in the sea areas around Japan. This deposit has been studied viewed from natural gas resources, causes for natural hazards and contribution to the global warming. This project excavates a well in the deposit, to study possibilities of the technologies for decomposing, fluidizing and lifting the hydrate as the gas source, and for establishing the natural gas transporting/mooring systems in which its characteristics are utilized. The R and D activities are directed to the 4 areas, (1) development of the exploration technologies to determine the deposit sea area, quantity and conditions, (2) development of the stable well-excavation technologies, (3) studies on the effects of gas production on the environments, and development of the system for predicting the effects, (4) and studies on the application systems. The item (3) finds out the transportation/storage system possibly more economical than the current freezing/liquefaction technologies. The item (3) has the development themes of evaluating the geohazards caused by excavation and gas production, and their effects on the ecological systems. (NEDO)

    Discussions and deliberations were given by the comprehensive survey committee on standardization of a total gene inspection system from specimen adjustment necessary for the gene inspection system to data processing. This paper summarizes the achievements in fiscal 2000. In standardization related to the specimen procedure and the inspection technique, the specimen storing method and the report statement contents were established. In addition, verification was made on the heat-resistant enzyme reagent and such measuring devices as the electric migration device and the photographing device. Discussions were given on standard substances used in the gene inspection. Regarding the K562 cell strain, cross-checking was performed in three institutions, wherein discussions were given on interchangeability of the inspection results, and the usefulness of the K562 cell as a standard substance. As a result, all the three institutions have come to an agreement on the Southern method, the FISH method and the RT-PCR method, but not on the real-time PT-PCR method, leaving the subject as the future assignment. In the survey for Europe and America, visits were made to AFNOR, CEN, DIN, FDA and CAP for the attempt of collecting information and establishing international exchange. (NEDO)

    The general analysis/assessment method of a fossil fuel cycle was studied. Seven kinds of power generation plants such as LNG cycle and coal cycle ones, and four kinds of transport and treatment systems of recovered CO2 such as ocean and underground systems were studied as case studies on life cycle analysis. As data necessary for life cycle analysis, the database was constructed which stores the facilities and operational energy required for a total energy system from mining of fossil fuel to treatment of recovered CO2, and the quantity of environmental waste such as CO2 emission. As a result, the decrease rate of energy balance defined as ratio of input energy to power plant output was estimated to be 14-43% and 20-60% in LNG cycle and coal cycle, respectively. Even if the recovery rate of CO2 in power plants reached 80-90%, reduction of total CO2 emission was limited to only 20-40% because of CO2 emission during mining, liquefaction and transport of fuel. 168 refs., 48 figs., 102 tabs.

    Although the next-generation phosphoric acid fuel cell has nearly reached its practical application stage as far as technology is concerned, its diffusion is yet to come due to lack of data about its cost efficiency and reliability. Under the circumstances, the goal now is to collect and analyze various data obtained in the above-named project which was started in fiscal 1997 for the compilation of data useful for full-scale diffusion in the future so that a foundation may be built for the overall popularization of the fuel cell. In this fiscal year, assessment and analysis have been conducted at 15 test sites now in presence. At the second plant of the Semboku LNG Terminals where approximately 17,000 hours have elapsed since the test began, the cell has operated for more than 16,000 hours in total. The Mycal Bore Sanda has established the longest uninterrupted operation record of 6,500. As for power generation efficiency, a town gas 13A-fueled system exhibits approximately 40% operating smoothly at a high overall efficiency of not less than 90%. (NEDO)

    With Akinomiya area (11.4 km{sup 2}) selected in Akita prefecture as the survey C area in fiscal 1996, the first survey was conducted. This paper is a summary of memorandum from an advisory standpoint on the evaluation survey concerning the fiscal 1998 investigation results. The contents of the survey are geological investigation, precision gravity exploration, soil gas investigation, electromagnetic exploration, fluid chemical investigation, well drilling and short-term eruption test. An alteration zone was recognized around the place where clay minerals used to be mined, with the center of the zone situated 500-600 m east of a fault. The alteration condition of Akinomiya area seems to be different from that of Doroyu Wasabisawa area. The supplementary gravity survey was carried out at total 58 points in fiscal 1998. It is desirable to set supplementary measuring points over a wide surrounding area for a depth structure analysis. Also performed was a study of mercury concentration in the soil gas. While CSAMT and TDEM methods were employed for the electromagnetic exploration, a suitable method should be carefully selected for a wide area high-density exploration. Consistency with adjacent areas is essential in preparing investigation items particularly for a geothermal model. (NEDO)

    Described herein are the FY 2000 results of the research and development of the fatigue characteristics of the bioceramics, fatigue and impact-resistance characteristics of the members of these materials, and methods of evaluating their compatibility with a living body, for proposing the international standards. The test results of alumina and zirconia as the bioceramics indicate that their bending fatigue characteristics greatly depend on environmental conditions and frequency, suggesting necessity for the evaluation in the environments which simulate the living body inside. The compression and impact tests are conducted for the artificial femoral heads with a taper. It is found that the simulated body fluid, having the dissociated ion concentration adjusted at the level in the human blood plasma, remains unchanged in the concentration at 36.5 degrees C for 4 weeks; the ion concentration is unaffected by filtration with the aid of the microfilter useful for, e.g., removal of bacteria; and the synthetic apatite has almost the same composition as that for the bones in a living body. It is also suggested that activity of the bioactive ceramics can be evaluated by their ability for forming apatite in the simulated body fluid. (NEDO)

    High-temperature properties of glass melts, e.g., density, volume expansion coefficient, surface tension, viscosity, specific heat, thermal and electrical conductivity, redox equilibrium and gas solubility, are basic factors that must be considered in high quality glass melting technology and computer simulation of the glass tank furnace. The structure of the glass melts is also important for understanding these properties. This R and D program is aimed at proposing the international standards for the methods of measuring these high-temperature properties of the melts. The 1988 efforts are directed to the measuring technologies for density, volume expansion coefficient, surface tension, viscosity, specific heat, thermal and electrical conductivity, redox equilibrium, gas solubility and melt structures of soda-lime-silica glass melts. The R and D for measuring methods for high-temperature melts through international cooperation and establishment of the international standards for these methods are proposed in the joint CGR/HVG/TNO/GPF conference, which provides the arena for information exchange by glass manufacturers.

    Long-term operation of a photovoltaic power generation system installed in a private residence in Osaka in 1992 is evaluated. Since the sale of power by back flow was approved five years ago, it has been working continuously without troubles. The evaluation covers the array output coefficient, inverter performance, system output coefficient, and power generation and sale track records. The findings obtained are mentioned below. Regular seasonal changes are observed in the array output coefficient, high in winter and low in summer, but the variation is smaller in amorphous arrays than in polycrystalline arrays. The monthly level of inverter performance is almost in all months higher than 0.90 specified for standard operation. The overall system output coefficient is 0.749, which is higher than the average value in NEDO`s field test business report. A total of 7852kWh has been generated since the system started operation five years ago, of which 3787kWh or 48% has been sold. 3 refs., 9 figs., 5 tabs.

    Autonomic neuropathy function immediately after a change to upright posture has been evaluated by applying transient response function of the system to the blood regulation system. The impulse response function was determined from the change in heart rate before postural change to the upright posture, and was compared with the transient change immediately after a change to the upright posture. The time series of R-R interval of electrocardiogram was used as the time series of the change in heart rate. To determine the impulse response function, an autoregressive model was applied to the R-R interval time series. The impulse response function at the steady state is a transient reaction at the impulse stimulation added to the blood regulation system. The R-R interval decreases rapidly by the autonomic neuropathy reaction in which the blood is rapidly transferred into the legs immediately after a change to upright posture. There is a close correlation between the initial temporary decrease in R-R interval and the impulse response function derived from the change in heart rate immediately after a change to the upright posture. Accordingly, the blood regulation and autonomic neuropathy functions can be evaluated by the impulse response function without actual standing test and load of tested persons. 9 refs., 3 figs., 1 tab.

    For the purpose of submitting propositions to ISO (International Organization for Standardization)/TC79 (Light metals and their alloys) and ISO/TC135 (Non-destructive testing), studies were made relating to the standardization of methods for chemical ingredient analysis and non-destructive testing of industrial pure titanium. In the development of an ingredient analysis method for pure titanium, performance standards and analytical allowance were determined for an inductively coupled plasma emission spectrochemical analyzer for vanadium, niobium, cobalt, and boron, which were short of completion in the preceding fiscal year. As for spark discharge emission spectrochemical analysis, analysis methods were newly established for oxygen and hydrogen. In the development of optical flaw detection for pure titanium boards, the quality of test pieces were determined by use of a reference test piece, and studies were made about the kinds of artificially produced flaws and a method for sensitivity calibration. In the development of ultrasonic flaw detection for pure titanium boards, studies were made about the effects of board thickness, kinds of flaws, and of board size. Using the findings, a draft standard was prepared in Japanese for a JIS (Japanese Industrial Standards) proposition and another in English for an ISO proposition. (NEDO)

    The purpose of this study is to develop a high-rate and clean chemical vapor deposition (CVD) process as a breakthrough technique to overcome the problems that particles generated in the gas phase during CVD process for preparation of functional thin films cause reduced product yield and deterioration of the films. In the CVD process proposed here, reactant gas and generated particles are electrically charged to control the motion of them with an electric field. In this study, gas-phase nucleation phenomena are evaluated both theoretically and experimentally. A high-rate, ionized CVD method is first developed, in which reactant gas and generated particles are charged with negative ions generated from a radioisotope source and the UV/photoelectron method, and the motion of the charged gas and particles is controlled with an electric field. Charging and transport processes of fine particles are then investigated experimentally and theoretically to develop a clean CVD method in which generated particles are removed with the electric forces. As a result, quantitative evaluation of the charging and transport process was made possible. We also developed devices for measuring the size distribution and concentration of fine particles in low pressure gas such as those found in plasma CVD processes. In addition, numerical simulation and experiments in this study for a TEOS/O{sub 3} CVD process to prepare thin films could determine reaction rates which have not been known so far and give information on selecting good operation conditions for the process.

    The bond quality of a solder-bonded copper laminated plate was modeled into rigid contact (rc) and slip contact (sc) to calculate the velocity dispersion of lamb waves. The velocity dispersion of laser generated lamb waves was measured, and the bond quality or the thickness of a solder layer was evaluated by non-contact. In the model whose bond surface is rc, the velocity dispersion of lamb waves can be calculated under conditions where the stress and displacement in an interface are continuous. In the model whose bond surface is sc, it can be calculated under conditions where an interface slips freely. Weak bond indicates the velocity dispersion between rc and sc. In this model, the velocity dispersion can also be calculated by a change in the thickness of a solder layer and used for quantitative evaluation of a bond interface. A three-layer solder bond manufactured for trial could be evaluated from the velocity dispersion of laser lamb waves. At the room temperature, the change in bond quality near the solder melting point of bond laminate that was judged as rc was investigated. When the solidus temperature is exceeded, the amplitude of lamb waves and the velocity dispersion changed largely. The amplitude of lamb waves increases as the liquid phase ratio increases. The bond quality near the solder melting point can be evaluated using lamb waves. 9 refs., 10 figs., 2 tabs.

    We developed a new laser surface acoustic wave (SAW) system and applied this to estimate the mechanical properties of the wear-resistant Ni-P layer electroplated on a stainless steel. The velocity dispersions of Rayleigh wave of the as -plated and heat-treated Ni-P layer were obtained by the one point time domain signal processing. The Ni-P layers with excellent wear resistance produced by the heated treatment higher than 725K were found to show higher Rayleigh velocities than that of the substrate steel, while the Ni-P layer with poor wear resistance showed lower velocities. Young`s moduli of the Ni-P layer, estimated so as the computed velocity dispersion agreed with the measured one, increased with the increase of wear resistance. 10 refs., 9 figs., 2 tabs.

    As part of validation processes of in vitro toxicity assays for the risk assessment of environmental hazards, we applied an in vitro toxicity test using two human cell lines, neuroblastoma NB-1 cells and glioblastoma U-87 MG cells, to the assessment of organochlorine compounds detected in the water environment. The in vitro toxicity assay using NB-1 cells was calibrated by testing reference chemicals proposed by MEIC (Multicenter Evaluation of In Vitro Cytotoxicity), an international program for the validation of in vitro cytotoxicity assays. Beforehand, an assay using cells in frozen stock without subcultivation was examined by comparing IC50 values with the ordinary assay using subcultured cells. IC50 values for MEIC reference chemicals from the former assay showed good correlation with those from the latter assay, suggesting that the assay using cells in frozen stock can be used at least for the assessment of basal cytotoxicity. IC50 values for ten organochlorine compounds frequently detected in the sediment samples from contaminated rivers, p-chloroaniline, 3,4-dichloroaniline, p-dichlorobenzene, o-dichlorobenzene, Tris (2-chloroethyl)-phosphate, 2,5-dichlorophenol, 2,5-dichloroanisol, Triclosan and Triclocarban, were obtained with the in vitro assays and compared with their LD50 values in rats. No significant correlation, however, was seen between the IC50 and LD50 values, indicating that further improvement of in vitro toxicity assays is necessary for the application to the risk assessment of environmental hazards. 7 refs., 4 figs., 1 tab.

    Assessment and examination were conducted on the scientific/technological aspect, environmental aspect and economic/social aspect concerning measures for mitigating climate change, as a part of international cooperation in global warming issues. In the development of assessment methods for cost analysis, it revealed that, in the activities for mitigating emission of greenhouse effect gases (GHG) or for increasing carbon sequestration, benefits of the mitigation sometimes surpassed their cost, allowing the society to benefit from the mitigation. In the examination of problems in technology transfer and their solutions, it was found that, in order to attain successful transfer, partnership among the parties interested was essential and that each government was capable of promoting such partnership. In the assessment of various policy options, the situation in the U.S. is such that the market aspect of GHG emission permit and credit trading is rather weak because of immaturity in a legal framework on GHG emission trading and because of undefinedness in the systems of the Kyoto Protocol and in the possibility of its validation. However, the reason enterprises are actively participating in the early market is that they plan a risk-hedge for example in anticipation of tighter regulations in the future. (NEDO)

    In order to develop the evaluation methods for reappearing corrosion characteristics of coated steel sheets in a short time, acid rain composition and artificial acid rain composition for the accelerated test were studied, and the cyclic corrosion tests were conducted. The literature survey shows that the main ionic species present in acid rain are Ca{sup 2+}, Mg{sup 2+}, Na{sup +}, K{sup +}, NH{sub 4}{sup +}, SO{sub 4}{sup 2-}, NO{sub 3}{sup -}, and Cl{sup -}, of which the acid rain components are SO{sub 4}{sup 2-} and NO{sub 3}{sup -}, their equivalent ratio (NO{sub 3}{sup -}/ SO{sub 4}{sup 2-}) in the Far Eastern area being 0.2 to 0.3. Therefore, the solution specified by ASTM 1141 is diluted 30 times with water to prepare the base solution for the accelerated tests, where its acidity is adjusted with a mixed acid of NO{sub 3}{sup -}/ SO{sub 4}{sup 2-} = 0.2 to 0.3 (pH: 3.0 to 4.0). Two sets of preliminary cyclic corrosion tests were conducted, one involving acid rain spraying, drying and humidification in this order, and the other acid rain spraying, humidification and drying. Analysis of the test data indicates that difference between these test cycles in corrosion rate is within a deviation range caused by different testing tools. Therefore, the former condition is adopted as the basis for the accelerated tests, because of its smaller deviation caused by different testing tools. (NEDO)

    With the purpose of establishing fundamental technologies for ceramic porous materials that are excellent for artificial bone for a living body, evaluation technologies were developed for mechanical properties and biocompatibility, with fiscal 1999 results compiled. Performed for the examination of the mechanical properties were flexural test, compression test, tensile test, shearing test, torsion test, fatigue test, etc., with an evaluation testing method studied assuming that ceramic porous materials were applicable to implanting members. In the evaluation of biocompatibility, five kinds of osteoblast-like cell lines were cultured on a plastic disk and a dense hydroxyapatite disk, with adhesion and proliferation of the cells compared. Since these osteoblast-like cell lines adhere and proliferate on the surface and in the pore of hydroxyapatite, evaluation of the biocompatibility such as cell affinity was found possible with this in vitro method. With the view of obtaining principles for designing new bioactive ceramics, a method was developed for evaluating apatite-forming abilities of metal oxide gels having different compositions and structures in simulated body fluid.

    Under the hydrogen-utilizing international clean energy system technology project WE-NET (World Energy NET Work) in fiscal 1998, researches and studies were conducted to clearly define safety designs and to improve on accident-and-safety analyses. In relation with system safety design, investigations continued into Japanese and foreign manuals and regulations about the handling of hydrogen and its peripherals, and safe design guidelines (draft) were compiled. Anomalies and accidents supposed to be typical of each of the systems concerned were investigated. As for accident-and-safety analyses, incorporation of a turbulence model was studied in relation to models representing the leak, evaporation, and diffusion of liquid hydrogen, and improvement was achieved when the scope of evaluation was enlarged concerning the hydrogen detonation model. The integration of the two models was discussed for the due evaluation of a series of processes of liquid hydrogen leak, evaporation, diffusion, and detonation. Calculation was performed for two assumed accidents, and the results were found to justify the integration of the two models. (NEDO)

    This report summarized German's proposed revised plan of Euro-NCAP (European New Car Assessment Programme) presently implemented in Europe. As to the estimation of car safety, by entrusting it to Technical University Berlin in the latter half of the 1980s, German has been studying since then and summed up the results as TUB-NCAP. In this proposal, three tests were conducted on full-lap, offset front collision, and European side collision. The car damage in each collision form in accidents on the market, frequency of occurrence of handicap of each crew member. By putting weight of each frequency on the data obtained from each test, the estimation can be made comprehensively in a scoring method. In this method, wherever the test is conducted, the whole car can be estimated in the quantified form in which the objective element is not included. And the effect in the market accident also increases, and the accurate information is conveyed to users. It is unknown that in what form this German proposal can be reflected by Euro-NCAP and other countries. (NEDO)

    As a part of the field test project for diffusing PV power generation into public facilities generally, evaluation and analysis were made on the collected data from 105 sites installed during fiscal 1993-1996. Analysis of operation characteristics was made by using parameters obtained by developing a basic equation for every component. 94% of all the sites fell under the total solar irradiation of 3.0- 4.5kWh/m{sup 2}/D. 83% of those fell under the equivalent array operation time of 2.5-4.0h/D. 70% of those fell under the equivalent system operation time of 2.5-3.5h/D. 72% of those fell under the system operation time of 9.0-12.0h/D. 78% of those fell under the effective inverter efficiency of 0.84- 0.96. 68% of those fell under the inverter load factor of 0.25-0.35. 85% of those fell under the array performance ratio of 0.7-1.0. 83% of those fell under the system performance ratio of 0.6-0.9. The generation cost decreased from 270yen/kWh in 1993 to 100yen/kWh in 1996 because reduction of an installation cost largely contributed to reduction of the total cost. (NEDO)

    In this paper, to evaluate the hydrogen production cost per unit volume, system optimization of solar hydrogen energy system is discussed. Based on the simulation of the I-V characteristics of amorphous Si (a-Si) photovoltaic array, the working point between the array and hydrogen generator was determined. The cost ratio of each design point was calculated. The optimum design points were 500 W/m{sup 2} for the single crystal Si system, and 600 W/m{sup 2} for the a-Si system. When the rating capacity of design point was constant, almost constant cost ratio was obtained independent of the type of photovoltaic cells. It was found that the photovoltaic cells can be fabricated in about 15% lower cost at maximum. It was also found that the optimum design point sifts to the lower insolation site due to reduction of the photovoltaic cell cost. Since the annual hydrogen generation quantity does not depend on the type of photovoltaic cells under the constant rating capacity of design point, hydrogen can be produced in lower cost by using photovoltaic cell of lower cost. 5 refs., 10 figs., 5 tabs.

    The biological effects of acute toxicity, chronic toxicity, carcinogenicity, etc. of chlorination by-products detected in drinking water in Japan are discussed. The biological effects of representative chlorination by-products such as trihalomethane, haloacetic acid, haloaldehyde, haloacetonitrile, chlorophenol, chloropicrin, etc. as well as the evaluation of mutagenicity in drinking water purification process, for which Ames Salmonella/microsome assay is used for safety evaluation of drinking water, are discussed. The extent of the contribution of mutagenicity of chlorination disinfection by-products to the mutagenicity of drinking water is investigated. It must be admitted that biological evaluation of the safety of water quality is impossible currently by using only the known chemical substances contained in drinking water. The effects of chlorination and ozone treatment which are often applied to drinking water treatment are different each other. 58 refs., 1 fig., 4 tabs.

    LCA (Life cycle assessment) is a systematic process used to calculate and evaluate the environmental impacts of products. Because boiler components are now exposed a more severe erosion/corrosion environment by, improving efficiency of thermal power plant, it is expected that the use of thermal spray coatings will increase. The LCA method was attempted to apply to various thermal spray coatings for PFBC (Pressurized Fluidized Bed Combustion) and evaluate the eco-friendly, coatings. The result was gained that all the alumina coatings have good characteristics. In fact the Al2O3-40%ZrO2 coating by APS has the lowest environmental impact and the best erosion resistance, it may be considered the most effective coating. 4 refs., 12 figs., 1 tab.

    Described herein are the final evaluation results of the basic research and development of the system for exploiting manganese nodules as one of ocean resources. A 9-year project was started in the FY 1981 to establish the techniques to efficiently, economically exploit Mn nodules on a commercial basis, which are occurring on deep sea bottoms (4,000 to 6,000 m deep), in order to stably supply non-ferrous metallic resources, e.g., Ni, Cu, Co and Mn, which are essential for economic activities of Japan. Originally, the UN convention related to ocean laws raised development of unique exploitation techniques as the prerequisite condition for obtaining the right to develop Mn nodules. However, the situations around development of Mn nodules were changed since then, to devalue objects, significance and urgency of this project. The fourth amendment of the basic plans decided to suspend the comprehensive ocean tests in 1996, and to implement only the ocean/land tests in which part of the individual elementary techniques were combined. Therefore, the technological validation of the overall system could not be done sufficiently, and degree of achievement of the project is low, viewed from insufficient prospects of the commercial production. However, this project produced good results in individual elementary techniques, which are of significance for the resources policies. (NEDO)

Infrastructure preparation for standards and public test and evaluation organizations for developing welfare equipment is being promoted by Technical Laboratory of Bicycle Industry Promotion Association and some national organizations such as Product Evaluation Technical Center, Mechanical Engineering Laboratory, National Institute of Bioscience and Human Technology, and Living and JIS Center. However, preparation of objective and across test and evaluation systems for developing welfare equipment is still insufficient. Product Evaluation Technical Center is now approaching to evaluation and standardization of welfare equipment. Public test and evaluation organizations of the UK, Sweden and Denmark are presented.

    Experiments were conducted to learn the impact damage on jet engine CFRP components for sucking birds or others. A great mass low velocity collision experiment using a falling weight and a small mass high velocity collision experiment using an air gun were conducted. The damages inflicted upon CF/PEEK (polyetheretherketone) laminates in the respective experiments were compared with each other by using the ultrasonic flaw detection method (C-Scan). There was a linear relationship in both experiments between the projected damaged area DA measured by C-Scan and the impact energy IE, enabling the relative evaluation of impact-withstanding damage characteristics by using the DA/IE ratios. DA/IE in the high velocity impact was higher than that in the low velocity impact, but the DA/IE ratio between the high velocity impact and the low velocity impact remained approximately the same, not dependent on the fiber orientation. The lamination parameter {beta} defined on the basis of the difference in-plane rigidity between the layers constituting the laminate is proportional to DA/IE, with {beta} enabling the generalized numerical expression of the impact of the fiber orientation upon the impact-withstanding damage characteristics. 9 refs., 5 figs., 2 tabs.

    With regard to endocrine disturbing effect being the new deleteriousness of chemicals, data were collected and evaluated by using the existing testing methods, data were collected by using the screening test, the testing methods were developed, and international investigation was carried out to establish the risk evaluation methods. In the evaluation by using the existing test methods, seven substance groups deficient in deleteriousness data qualitatively and quantitatively were given reproduction toxicity tests to evaluate availability of the endocrine activity. Development of the screening test method has been carried out by participating the validation test by OECD to make the uterotrophic assay method and the Hershberger assay method a test guideline having international matching property. International investigations to establish the risk evaluation were executed on the molecular mechanism of nuclear receptors, the chemical, metabolic and environmental behaviors of endocrine active substances, the effects of the endocrine active substances on experimental animals and human, the utilization thereof for risk assessment in human, and the effects of endocrine disturbance acting substances in wildlife species.

    Source spectra and site effects are separated using the aftershock records, and the characteristics of short period earthquake motion in Higashinada Ward, Kobe City including the area to the south of seismic intensity 7 area are investigated placing emphasis on how far the site effects can be explained by 1-D ground structure. The shape and amplitude of the site effect of KNN and KYC located outside the seismic intensity 7 area can be explained fairly well by 1-D multiple reflection theory of S wave. However, peaks near 3 to 4Hz of KNN and UOZ in seismic intensity 7 area can not be explained. This suggests that the site effects of seismic intensity 7 area obtained by the aftershock records might include 2-D effects of underground structure. Inversion is performed using site effects as the objective functions to determine S wave velocity structure and Qs in the sedimentary layer. S wave velocity structure shows no systematical difference from those of the past models. 22 refs., 13 figs., 2 tabs.

    At present, in oil refineries in Japan, the term of the continued operation in oil refining facilities is shorter than that in Europe and America because of the regulation on the open inspection period for boilers and hazardous material storage tanks. As a result, the refining cost is comparatively higher than in Europe and America due to the increase in inspection/repair cost and decrease in operational rate. Therefore, it is becoming important to effectively supply petroleum products by keeping stability in oil refining facilities of the whole Japan and prolonging the term of the continued operation of oil refining facilities, etc. In this R and D, the technical development is conducted which is needed for the long-term continued operation of oil refining facilities. The items for the R and D are as follows: assessment technology of reliability of oil refining high temperature system facilities, assessment technology of reliability of piping/storage facilities in oil refinery, assessment technology of reliability of oil refining power system facilities, technology of management support system in oil refining facilities. In this fiscal year, technical survey, data collection, and construction of the basic concept of developmental technology were mostly conducted. Also conducted were trial manufacture of various probes for non-fracture inspection use, oscillators, etc., and basic design of inspection equipment and trial manufacture of a part of them. And the data acquired were analyzed. (NEDO)

    An objective evaluation from a third party was conducted on the purpose, plan, execution method, achievement, etc. of a project 'The devilment of the catalyst surface high accuracy quantitative analysis technology using electron spectroscopy.' The purpose of the project is to make the relationing possible between the analytical results of the catalyst surface and the catalyst performance which has been so far difficult by heightening the accuracy of the catalyst quantitative surface analytical accuracy using the electron spectroscopy. The purpose and significance are judged to be worth a lot. This project is an industry/university/government joint project between the two countries. The project is excellent both in connection among research institutes and leadership of chief researchers, and it is judged that the joint research system fully functioned. The term of the project was shortened from 3 years in the first plan to 2 years, and therefore, the study was finished only on silicon oxide and organic thin films. However, it was determined that the study results are to be run in the magazine 'Surface and Interface Analysis,' which indicates that the achievement was judged to be very worth in the academic viewpoint.

The method was applied to estimate the strength of coal-water interaction in two different coals and to estimate the enthalpy change deriving from the change in hydrogen bondings during the desorption of water. The estimated enthalpy change was compared with the total enthalpy change estimated by DSC measurement to examine the importance of hydrogen bondings during the desertion of water. 1 ref., 6 figs.

    As characterization of artificial cracks formed underground by using the water pressure fracturing method, experiments have been carried out to detect relationship of pressurization and S-wave propagation time with the polarizing direction dependence. Openings are created when pressure in the vicinity of the artificial cracks increases greater than reopening pressure of micro cracks. Elastic wave velocity decreases in this region because of water in the opened micro cracks. Anisotropy is created in the S-wave propagation velocity due to influence from anisotropic reopening region when the artificial cracks are pressurized, and is separated into two components which polarize orthogonally with each other (micro splitting). Field experiments conducted at the Higashi-hachimantai field were analyzed by using wavelet transform. It was possible to detect the S-wave arrival time at high accuracy, and the arrival of an orthogonally polarized wave was observed in 0.03 to 0.11 ms after the arrival of the S-wave. Possibility was indicated on separation of the two components in the orthogonally polarized wave of the S-wave if the micro splitting is used. If this mechanism is elucidated, it may be possible to extract information on cracking systems (direction of micro crack orientation and crack density). 8 refs., 10 figs.

    Development of a bituminous coal liquefaction technology (NEDOL method) can be judged appropriate as a national project in the comprehensive view with the 21st century just around the corner. It is a fact that this project has spent the national budget not in a small amount. There is no prospect of the technology to be put into practical use in Japan at the present time. The coal liquefaction technology is a technology required inevitably in the situation where shortage of crude oil supply may endanger the existence of a nation. Therefore, there is sufficient significance in having demonstrated the effectiveness of the NEDOL method which can be applied to a large number of coal types and expected of high liquefaction yield. The contents of the 'technological package' to be prepared are so demanded that its usefulness can be retained until the time of a demonstration plant design and operation will come in the future. It is also desired that the human resources and the testing devices will be kept ensured, and the technologies developed under this project will be maintained and expanded. The present technology has low necessity of immediately putting into practical use in Japan at the present time. However, the technology should be kept available for use at any time, and retained for use in an urgent situation. (NEDO)

    The effort of fiscal 1997 at isolating the best way to introduce a relatively small amount of hydrogen into urban fuel economy was carried over to fiscal 1998. In the research of fiscal 1998, comparison was made between Tokyo and London in connection with hydrogen introduction, and a transition scenario was proposed for introducing hydrogen into Tokyo. Models were built for Tokyo and London, and studied. The result of this study was different from that obtained in the previous study, and places the two cities under similar conditions. The difference is attributed to the rapid progress in the development of the fuel cell and to the resultant reduction in cost. It is inferred that, in consideration of the transportation situation, the introduction of pure hydrogen will be the most cost-effective for both cities at least for some time to come. According to the revised data, natural gas may be procured in Tokyo as in London but the size of supply available in Tokyo is fairly smaller than that in London. Several transition scenarios covering the period up to 2025 were subjected to discussion. (NEDO)

The equipment at Hiraizumi had a rated output of 490 kW, and at Miura 400 kW. The period of the examination was from April, 1998 through February, 1999, the items for data collection being the generator output, generated energy, average wind velocity, record of abnormality occurrence, and maximum wind velocity. At Hiraizumi, annual average utilization rate was 12.9%; annual average operation rate, 49.9%; average wind velocity, 4.6 m/s; and maximum wind velocity of the period, 31 m/s. At Miura, annual average utilization rate was 16.5%; annual average operation rate, 77.0%; and average wind velocity, 5.0 m/s. The utilization rate is desirably 17%. The top three abnormalities were drop in AC control voltage, actuation of main shaft brake and eddy current/actuation of open phase relay, accounting for 83.3% of the total abnormalities at Hiraizumi, while they were unbalance in current, grid drop and automatic unwinding of cable, accounting for 74.5% at Miura.

    This study was conducted to standardize the chemical analysis and non-destructive inspection methods for pure titanium metals of industrial grade. These methods are among those serving bases for international standardization of products. The chemical analysis is aimed at quantitative analysis of trace impurities, in particular, present in pure titanium metals of industrial grade by developing and standardizing the inductively coupled plasma atomic emission spectroscopy, known for its low detectable limit, and, at the same time, spark and glow discharged atomic emission spectrometry as the improved routine analysis methods. These methods, although being used by, e.g., steel makers, have not been standardized because the effects of titanium-peculiar matrix are not elucidated. The non-destructive testing is aimed at standardization of the techniques useful for automatic production lines. More concretely, these include optical methods aided by a laser or CCD camera for plate surface defect inspection, ultrasonic methods for plate internal defect inspection, and pressure differential methods for air-tightness of welded pipes. They have not been used yet for automatic production lines. (NEDO)

    This paper evaluates impacts of the maturity of Japan`s economy and society and the improvement in automotive fuel efficiency on the demand for automotive fuels by FY 2010. Standard case and lower order case were examined. When the traffic volume of passenger cars in FY 1995 is assumed to be 100, it become 121 and 119 in standard and lower order cases, respectively. The traffic volume of lorries become 106 and 102 in standard and lower order cases, respectively, which showed a rather small growth. Deterioration rate of the fuel consumption was estimated by considering the difference in fuel consumption of new cars and existing cars. Although the fuel consumption will be lowered by FY 2000 when the cassation rate of ordinary passenger cars will rapidly increase, the impact will be lowered after that. For lorries for commercial use, the running fuel consumption will be gradually lowered due to the increased carrying capacity and vehicle weight a lorry with improving the transportation efficiency. Decreased running speed by traffic jam is also a cause of the deterioration of fuel consumption. When a policy of improvement in the fuel consumption is promoted in a background of CO2 issues, the fuel consumption of each vehicle will be gradually improved. The peak of fuel demand will be in FY 2005 by considering the changes in economical and social structures and the improvement in fuel consumption for the environmental protection. 5 figs., 3 tabs.

    The objective of this study is to examine the mechanical properties of construction joints between existing and newly placed concrete under combined tensile and shear stresses. Loading tests are conducted by using push off type specimens. The joint surface of existing concrete is roughened by shot blast and a half of the specimen is reconstructed by new concrete using ultra rapid hardening cement. The insufficient treatment of joint surface of the old concrete causes the lowering of tensile rigidity, while shearing rigidity is almost the same as that of the other specimen. The shearing and tensile rigidities of non jointed concrete and concrete shot blasted properly are not dependent on the combination of shearing and tensile forces. For the jointed concrete shot blasted insufficiently, the shearing rigidity decreases with the increase of tensile force and the tensile digidity also becomes lower by the action of shearing force. Both the tensile strength and shearing strength of jointed concrete become small compared to those of non jointed concrete. The ratio of reduction in tensile strength is larger than that in shearing strength. The strength of jointed concrete under combined tensile and shear stresses can be evaluated by Mohr`s failure envelope expressed by parabola tangent to both tensile strength circle and compressive strength circle. 7 refs., 12 figs., 2 tabs.

    The results achieved in fiscal 1992-1995 under the above-named project are stated. In the development of photocatalytic materials, a photocatalytic fluorocarbon polymer sheet suitable for use in a denitration apparatus is developed. A high density fluorocarbon polymer sheet composed of TiO{sub 2} modified with 0.3% of Pd/absorbent zeolite/fluorocarbon polymer PTFE (polytetrafluoroethylene) =48-63/24-36/10-20 is fabricated, which achieves a level higher than the denitration goal of 70%. Although the sheet in a 500-hour accelerated exposure test undergoes a hardening phenomenon in which elasticity decreases and tensile strength increases, yet degradation is hardly detected. Although a slight reduction is detected in denitration efficiency, yet it does not affect its practical application, and thus the durability goal is achieved. In the development of an energy conservation type air cleaning apparatus usable in underground parking areas or motorway tunnels, an apparatus capable of treating air at a rate of 2,000m{sup 3}/hour is fabricated, and this achieves a denitration level of not less than 80% in a field test (in the absence of rainfall). For denitration in the presence of rainfall, the apparatus is combined with an equimolar adsorption system, and a system capable of 80% denitration is proposed on the basis of data actually measured for each of the two. A conceptual design for a service model comprising a photodenitration and equimolar adsorption systems is evaluated, and it is found that it occupies less space than the existing models. (NEDO)

    This paper describes a hydrogen transportation system utilizing metal hydrides. For a storage method for moving, metal hydrides having high hydrogen containing performance like Mg-based hydrides would have high portability, less weight disadvantage, and high economic performance. In the fixed location storage, metal hydrides are superior in safety and maintenance cost to the conventional high-pressure gas holder and liquefied hydrogen storage. Because of their high dependence on equilibrium pressure and temperature, the significance of development thereof is large as the source of high-pressure hydrogen generation and motive force. More effective utilization of low-level heat, and separation and refining of hydrogen may also be expected. With regard to fuel supply for hydrogen fueled automobiles, metal hydrides are better in safety and total energy cost than liquefied hydrogen, but have a number of disadvantageous points in weight demerit. Eliminating the weight demerit would be the central issue of the development. Accompanying the development of hydrogen fueled automobiles, there are a number of technological elements to be developed on fuel supply system, such as storage, moving and transportation in hydrogen manufacturing sites, and filling and storage at using sites. Arranging the related infrastructures would be the issue. (NEDO)

    This paper describes comprehensive evaluation and analysis mainly on the 51 items adopted in the high-performance industrial furnace introduction field tests. The development of a high-performance industrial furnace has completed the fundamental development research in fiscal 1998, and the possibility was verified on energy saving of more than 30% and reduction of NOx emission by 50% over that by conventional furnaces. Upon this fundamental achievement, the field test project has started as the comprehensive approach to developing the practically usable technologies for three years from fiscal 1998 until fiscal 2000, which is being promoted as a joint research project. According to the survey on the actual state in fiscal 1998, a little less than 20,000 industrial furnaces having combustion capacity of more than 500,000 Kcal/hr (excepting boilers) are being used. If these furnaces are converted into the high-performance industrial furnace, energy conservation of 210,000 x 10{sup 6} Mcal (converted to crude oil of 22.7 x 10{sup 6} kl/year) can be achieved from the maximum annual energy consumption of 700,000 x 10{sup 6} Mcal (converted to crude oil of 75.7 x 10{sup 6} kl/year). This conservation amount corresponds to about 12% of the final energy consumption in the whole Japanese industrial departments in fiscal 1996. It is expected that the performance of the full-size high-performance industrial furnace will be verified, and this technology will be promoted for wide proliferation. (NEDO)

    Technological development is in progress at present for the intelligent transport system for example that uses a microwave frequency range of 60GHz or 90GHz toward the practical use, with a demand increasing for measuring the electrical properties of fine ceramics (FC) to be used in the communication equipment of the system. The measuring method in the microwave frequency range of 30GHz or less is about to be standardized in IEC TC49/WG10; however, the method above 30GHz has not yet been examined for the standardization internationally. The subject research is intended to establish the method of measuring electrical properties such as the dielectric constant of FC for a high-frequency/ultra high-frequency wave range, dielectric loss and surface resistivity, to standardize the principle of their measuring methods, measuring tools, adjusting method of samples, procedures of measurement, etc., and to aim at the international standardization. This year, investigation and examination were carried out on various measuring methods including overseas examinations in the U.S., extracting the Fabry-Perot resonator method and a conductive cylindrical dielectric cavity resonator perturbation method for example, and evaluating the specifications of standard reference materials. In addition, a morphological technique was established for measuring sample surfaces affecting measurements, by means of an accurate measuring instrument for thin film surfaces. (NEDO)

    A proposal was given on an equivalent crack tip opening displacement (CTOD) concept which relates quantitatively fracture performance of a structural member with the result of a three-point bending CTOD test via the Weibull stress based on a local approach. The equivalent CTOD is defined as a CTOD in which a three-point CTOD test piece and a structural member provide the same Weibull stress. Experimental and analytical discussions were performed on X80 steel welded joints. Effectiveness of the equivalent CTOD concept was verified from the fact that the fracture performance in welded joints with a large width estimated from the result of the three-point bending CTOD test using the equivalent CTOD concept showed good correspondence with the fracture performance obtained in the experiments. On the other hand, the result of estimation using the conventional CTOD concept is considerably smaller than measurements. As an application of the equivalent CTOD concept, a new determination procedure was introduced on required fracture tenacity to ensure deformation performance required on structural elements. The required CTOD value shows a trend that the smaller the ratio of yield stress of the welded metals to that in the base material, the greater the required CTOD grows. 16 refs., 19 figs., 3 tabs.

    With the purpose of establishing fundamental technologies for ceramic porous materials that are excellent for artificial bone for a living body, evaluation technologies were developed for mechanical properties and biocompatibility, with fiscal 1999 results compiled. Performed for the examination of the mechanical properties were flexural test, compression test, tensile test, shearing test, torsion test, fatigue test, etc., with an evaluation testing method studied assuming that ceramic porous materials were applicable to implanting members. In the evaluation of biocompatibility, five kinds of osteoblast-like cell lines were cultured on a plastic disk and a dense hydroxyapatite disk, with adhesion and proliferation of the cells compared. Since these osteoblast-like cell lines adhere and proliferate on the surface and in the pore of hydroxyapatite, evaluation of the biocompatibility such as cell affinity was found possible with this in vitro method. With the view of obtaining principles for designing new bioactive ceramics, a method was developed for evaluating apatite-forming abilities of metal oxide gels having different compositions and structures in simulated body fluid.

    In general, it is most efficient and economical to install photovoltaic (PV) modules with proper slope. There are room spaces on the wall except ground or roof. The PV modules were installed on the vertical wall, to consider the compensative method for this weak point. When modules were installed vertically, there is an advantage that reflecting solar light as well as incident solar light can be utilized compared with the installation with slope. The PV modules were installed on the roof of building with inclination of 90{degree} facing to south using the roof material as a reflecting material (S90), and with inclination of 15{degree} facing to south (S15), to compare their output. The output ratio, S90/S15 was 0.42. When it was very fine, this value increased to 0.60. When using plated steel plate as the reflecting material, this value increased to 0.74, which provided 10 to 30% larger output than the roof material. From these results, about 50% of module output of S15 can be expected for S90. If receiving larger reflection, there would only a slight difference in the module output between S15 and S90. 3 figs., 1 tab.

    In the field test project for the photovoltaic power generation for public facilities, operational data were collected/analyzed on facilities at 158 sites installed from FY 1994 to FY 1997. As a result, the following were found out: Average values of the global radiation on an inclined surface, equivalent array operation time, equivalent system operation time, system operation time, inverter performance efficiency, inverter load factor, array power coefficient, and system power coefficient are 3.51 kWh/m{sup 2}/D, 2.72 h/D, 2.47 h/D, 10.3 h/D, 0.91, 0.30, 0.77 and 0.70, respectively. No deterioration with age was recognized in the 4-year operation data. As to the maintenance, the item, 'there are a lot of failures in the photovoltaic power system,' was 2% in rate. As to the inspection, times are mostly once a month. The annual maintenance cost was widely between about 360 yen/kW and about 30,000 yen/kW. Supposing annual expenses to be a total of capital expense, direct expense, and general administrative expense, the power generation cost dropped from approximately 240 yen/kWh in FY 1994 to 100 yen/kWh in FY 1997.

    This paper summarizes the basic materials related to unified evaluation models for global warming. The unified evaluation is a disciplinary process to combine, interpret and share the information from different scientific disciplinary areas in such a form that the whole cause and effect chain can be evaluated from a macroscopic view. The process has higher utilization value than the evaluation overemphasizing a single academic area, and can provide decision makers with useful information. The process is suitable to model complex interactions and feedback mechanisms in diversified scenes such as climate change. The unified evaluation can identify the policy criteria along with a measure framework having consistency. The evaluation process is repetitive and continuous, wherein a science community can convey comprehensive knowledge and finding to a decision making community. In turn, the decision making side can feed back the experiences and achievements in learning. Execution of the evaluation requires different approaches, such as judgement of specialists including the modeling methods and experience, discovery as a result of applying the policies, and survey methods. The paper also describes the gaming conception, scenario analysis, and unification evaluation methods. (NEDO)

    This report summarizes results of the phase II R and D program of MHD electrical power generation (FY 1976 - 1983), which has been now completed. The phase II R and D efforts were concentrated on development of the durable power generation channels, where the designs and manufacture of the Mark II system were started, and the elementary techniques were simultaneously studied for, e.g., phenomena occurring around the electrodes, seed condensation and its effects on the electrode phenomena, and electrode and insulator materials for the power generation channels. The power generation channel was tested for its durability for a total of 430 hours, after it was incorporated in the Mark II system. The MHD power generation can incorporate direct combustion of coal, and will hold a dominant position in coal-fired power generation, which is expected to grow in the future. For this reason, the basic research schedules were revised in March, 1983, and the Mark II system was operated by firing a mixed fuel of kerosene and finely divided coal in a kerosene combustor, in line with the revised project, to understand the basic power generation characteristics with the combustion gases containing coal slag.

    Researches were conducted with a view to organizing projects for developing intelligent fibers, equipped with environmental friendliness and amenity without being deprived of their original properties as structural and clothing materials, the ultimate goal of the effort being the creation of harbingers of next-generation fibers which would contribute to the advance of industries related to environments, medicine and welfare, and information. What were learned from fiscal 1998 researches are mentioned below. The strength that the general-purpose fibers currently in use exhibit is so small as to be but several percent of what is theoretically predicted for them. Demand will increase a great deal if the actual strength is doubled, for which new technologies have to be developed including those involving super-fiber texture control. For providing the fiber with such functions as environment-friendliness, amenity, etc., it is necessary to develop phasal structure control technologies with regard to fiber morphology, surface texture, etc. For success in practical application in the future of such super-fiber materials, each specimen needs to be manufactured in the order of kilogram by way of trial. Moreover, fiber evaluation techniques have to be developed in the three domains of software, hardware, and interface. (NEDO)

    This paper is a generalized report in relation with the mine waste water treatment technology utilizing biotechnology, from among the promotion projects for research cooperation with China. Ferric iron (Fe{sup 3+}), which precipitates at low pH, is produced by utilizing bacteria which derives energy from oxidizing ferrous iron (Fe{sup 2+}) in the waste water, and the iron is precipitated and removed by using low-cost calcium carbonate as a neutralizing agent. Joint researches and developments have been carried out on selection of optimal kinds of bacteria, cultivation of bacteria oxidizing iron at high efficiency, optimal removal system of heavy metals in mine waste water, and recovery of useful resources. Japanese engineers were sent to sites in China, Chinese researchers were received in Japan, and pilot plants were operated and studied. For the purpose of proliferating and enlightening the result of the project, a seminar was held in Beijing in February 1998. In order for the achievements derived up to fiscal 1998 to be used in diverse fields, fiscal 1999 will carry out follow-ups, including assistance, for the voluntary researches performed by China. The follow-ups will also include confirmation on the state of testing the iron oxidizing bacteria technology, technical guidance, and analyses and discussions on the data. (NEDO)

    For the promotion of research exchanges on global environmental preservation with developing countries, Ms. Malee Santikunaporn, lecturer of Faculty of Engineering, Thammasat University, Bankok, Thailand was invited. Desulfurization/denitrification facilities, which are being widely spread in developed countries, have marked effects, but high prices are an obstacle to the spread in developing countries. To make them spread in developing countries, it is needed to develop the technology which is low in price and meets the actual state in developing countries. As a technology with high viability, a system to simultaneously remove SOx and NOx was cited in which Cu is used as catalyst and adsorbent and into which the catalyst regeneration process is integrated. Considering it, technical exchanges on Cu-SiO{sub 2} catalyst as the basic theme were made during September 26 - December 23, 1999. Through visits on and exchanges with Tokyo Institute of Technology, ICEET, University of Kyoto, etc., understanding was deepened about how each country is tackling environmental problems. The theme 'Oxidative sorption of SO2 by Cu-SiO{sub 2} catalyst: characteristics of catalyst' could deepen knowledge/information of the developmental research as a system for simultaneous removal of SOx/NOx. The data obtained indicated great practicality of Cu-SiO{sub 2}. (NEDO)
