    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.

    Full Text Available Phalaenopsis “Sogo Vivien” is an orchid hybrid with mini size plant body, and exhibits numerous beautiful pink flowers, that is ideal as ornamental pot plant. Some plants of this orchid exhibit variegated leaves that improve the beauty of the plant, not only because of the flower but also as attracted leaves. This orchid has high economical value, but mass propagation of this orchid has not established yet. An effective method to propagate both the normal and variegated plants is worth to be generated. The objective of this research was to produce a large number of P. “Sogo Vivien” plants, including the variegated plants. The method used seeds from self pollinating variegated plant, and flower stalk nodes. The seeds were sown on three various medium: VW, NP and MS, and flower stalk nodes were planted on VW + BA 10 mg l-1 + active carbon. The results showed that the best medium for in vitro culture of P. “Sogo Vivien” was NP medium, in which all seeds could grew into plantlets. Most plantlets emerged from the seeds were non variegated, only one plantlet out of 1344 seeds was variegated (0.007%. Although all emerged plantlets from flower stalk exhibited variegated leaves. Particularly, the plantlets arised from the second and third basal nodes of flower stalk showed the highest growth rate than that from the other nodes. Histological analysis showed that at 11-13 days after shoot segment plantation on NP medium, the shape of apical cells in the nodes was changed, then followed by the change of cell shape in the basal part of the nodes, produced bipolar pattern, then gradually developed into shoot. These results suggest that mass propagation could be achieved using seed culture, but to get the variegated phenotypes, the second and third nodes of flower stalk from variegated plant were the best explants to be used.

    The deep-sea manganese nodule mining system in this report collects efficiently and continuously a large quantity of manganese nodules in existence in the 5,000m-deep sea floor. The aim of the project is to develop and build an experimental system for a real mining machine and to perform a comprehensive marine test to find out if such a real machine is technologically and economically feasible. The system under this project is divided into four systems, which are a nodule mining system, nodule lifting system, nodule handling system, and a measurement control system. The nodule mining system travels on the sea bottom efficiently collecting manganese nodules and forwarding them into the nodule lifting system. Only a few systems of this kind have so far been developed, however, and therefore much endeavor needs to be exerted for the development of technologies involved. The nodule lifting system is divided into a pump lift unit, air lift unit, and a nodule lifting pipe. The pump lift unit and air lift unit elevate manganese nodules supplied from the nodule collecting unit to the sea surface. The nodule lifting pipe provides a passage for nodules to run through upward. (NEDO)

    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.

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.

    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.

    This research was conducted to exploit the waste of used plant parts from the widely marketed moth orchid cultivar ( Phalaenopsis Sogo Yukidian "V3"). Various extracts of roots, stems, and leaves were evaluated for total phenolics, total flavonoids, and antioxidant capacity. The bound extract from stems contained the highest total phenolics (5.092 ± 0.739 mg GAE (gallic acid equivalent)/g DW (dry weight)). The maximum total flavonoids (2.218 ± 0.021 mg RE (rutin equivalent)/g DW) were found in the hexane extract of leaves. Ethyl acetate extract from roots showed the greatest antioxidant activity compared to other extracts. Of these extracts, the IC 50 values of these samples were 0.070 mg/mL, and 0.450 mg/mL in a free radical 1,-diphenyl-picryl-hydrazyl (DPPH) assay and reducing power method, respectively. The lipid peroxidation inhibition (LPI) was found to be 94.2% using the β-carotene bleaching method. Five phenolic compounds including caffeic acid, syringic acid, vanillin, ellagic acid, and cinnamic acid were quantified by high performance liquid chromatography (HPLC). It is suggested that the roots of the hybrid Phalaenopsis Sogo Yukidian "V3" cultivar may be exploited as an effective source of antioxidants.

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

    With an objective for spatial continuous measurement of physical, chemical and biological amounts in ocean, development has been made on a wing controlled towed vehicle, `Flying Fish` which is capable of controlling depth, pitch and roll. Numerical simulations and two-year sea experiments have been carried out for the development. Flying Fish consists of a sub-system comprising a towing vehicle, towing cables, and on-board controllers. In a steady state, Flying Fish can be controlled at accuracy for depth of {plus_minus} 0.05m, pitch of {plus_minus} one degree, and roll of {plus_minus} 0.5 degree. This accuracy is sufficient for operating a chemical analyzer, the dissolved carbonic acid analyzer. Even in a non-steady state such as in changing the depth, the pitch can be controlled at {plus_minus} 3 degrees and the roll at {plus_minus} 0.5 degree. This extent of attitude change is within a range rendering no problems in maintaining accuracy of the measurement devices. The result of sea experiments for movements of Flying Fish agreed with that of the numerical simulation at practically usable accuracy. Flying Fish is verified as an effective system in investigating spatial variations in ocean data. 10 refs., 15 figs., 1 tab.

    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 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.

    A conceptual framework for evaluation of sealing capacity was designed to provide a predictive tool for raps. Data on the sealing capacity were re-examined by a working hypothesis applied to case studies of the oil and gas fields concerned with exploration projects of The Japan National Oil Corporation. A seal data-base was thus constructed. A flow chart for seal evaluation was designed with regard to classification of traps into Capillary Limited Traps and Spill-Point Limited Traps. These results could form a contribution to a 3D modeling of trap prediction in the near future. (author)

    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)

    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.

    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.

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.

    `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.

    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.

    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.

    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)

    Research, development and evaluation were performed with an objective of establishing the basic technology related to light-reactive materials that control the structures and status of aggregation of molecules by using actions of light, and can be used for ultra-high density recording, high resolution indication and light switches. In elucidating the mechanism of light deterioration reaction of photochromic molecules, it was disclosed that 6-nitrospirobenzopyran has the light deterioration caused from the excitation triplet state. 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.

    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)

    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. An experimental system was developed to measure the effects of the scents to relax work stresses. A screening method was developed, whereas effects of 15 kinds of scent materials were investigated.

    This study is intended to establish a basic technology for innovative high-efficiency separation membrane materials that can be used in areas in which application of membrane separation has been impossible. The water/ethanol separation membrane (for water selective permeation) and water/acetic acid separation membrane (for water selective permeation) achieved separation coefficient and permeation velocity of the world's highest level. The water/ethanol separation membrane (for ethanol selective permeation), although its separation coefficient is lower than the world's highest performance, has high permeation velocity, providing the performance of the worldwide level as seen from the comprehensive viewpoint. The carbon monoxide/nitrogen separation membrane achieved separation coefficient and permeation velocity of the world's highest level. The oxygen/nitrogen separation membrane requires further enhancement in the permeation velocity and stability. Establishment has been performed on separation technologies for membrane separation of non-water soluble aqueous solutions, optical division by using chiral crown ether, high-performance liquid separation by means of plasma surface treatment, and particle separation.

Through the observation of super spiral DNA fixed on a spermin or spermidine treated mica substrate by AFM (atomic force microscope), fixation of DNA without any deformation in solution was clarified, and visualization of the spiral structure of DNA were successfully achieved. Manipulation of Xe atoms adsorbed on an Si(111) surface was certainly possible by using STM (scanning tunneling microscope)/atom probe equipment. A nucleation mechanism in crystal growth was studied for various organic source-molecules/GaAs(001) surface systems, and formation of high-density nuclei on the GaAs surface was achieved by accelerating the translational energy of Ga material molecules up to 6eV or more. Ziegler- Natta catalysis important for industrial polymerization of olefin molecules was precisely analyzed by first-principle dynamic simulation.

    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 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.

    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.

    In this research, the photovoltaic power system is experimentally installed at various facilities (public facilities such as public hall, school and museum), and operated on a long term basis under the actual loads. Various kinds of data are collected/analyzed and used as the data useful for the full-scale introduction and spread. The photovoltaic power generation field test project for public facilities using the photovoltaic power system was started in FY 1992 by NEDO. Systems at 116 sites started operation by FY 1996, and in FY 1997 systems were installed at a total of 70 sites. The paper outlined the project and described the results of the collection/analyses of the operational data obtained at 145 sites where systems were installed from FY 1995 to FY 1997. The term of analysis in FY 1999 was made from April 1999 to December 1999, being different from usual, to avoid the Y2K problem on data collecting software, measuring use personal computer, etc. Further, since there are no sites where no systems were newly installed in and after FY 1998, there are no analyses of economical efficiency in and after FY 1999. The paper indicated a list of all the sites with system installation in FY 1995-1997 including the main items. (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)

    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.

    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 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.

This paper summarizes the achievements in fiscal 1997. The current fiscal year has performed the continued collection of data of the demonstration operation, and analysis and evaluation on the photovoltaic power generation characteristics and the house load characteristics. 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 proposing the optical evaluation method of appearance of the apparel as an international standard, studies were made of the following: 3D determination/assessment method, development of mannequin holders, development of shape-retentive cubic replicas, washing/drying conditions, etc. As to the shape retention, cubic replicas for collars and cuffs were manufactured and inputted as image data. Besides, as to the evaluation items such as wrinkles, seam-puckering and pleats, the class determining algorithm was made by comparison between the measuring data and the results of the human-sight measurement. These were embodied into mannequin holders and integrated into the optical 3D instrumental system, which was discussed as a 3D determination/assessment system. By the development of the 3D measuring system and image analysis program, a comprehensive evaluation system was developed which can determine/assess the performance of shape stability of the apparel optically as absolute evaluation. This method will be internationally proposed as an optical evaluation method of the appearance of the apparel. 86 figs., 8 tabs.

    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)

    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.

    Living standards improving in developing countries especially in China are the most influential factor to determine the demand for Cu. Consumption of Ni will depend on the trends of advanced technologies such as Ni-hydrogen battery, fuel cell, shape memory alloy, hydrogen absorbing alloy, in addition to increase in global population and developing countries' living standards improvement. Co is far more dependent on advanced technologies than Ni is. On the land, Ni ore is increasingly lower in quality and Co is being retrieved from by-products of Cu production, both meeting the problem of unstable supply. Consideration is made to apply new extraction methods to Cu production; there are some potential resources for Fe and Mn. The Mn nodule exists in great quantities and is a attractive source of supply, but a long time will be required before it is exploited. It is necessary to speed up the study to exploit the Mn nodule, but first of all the problem of its competition with land resources in terms of cost has to be solved. It needs to be found out at what stage of production the Mn nodule is competitive with land products. In any case, Japan should undertake the efforts of marine resources exploitation leading other countries of the world. (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)

    This paper introduces a subjective evaluation on a thermal environment. Providing human being with an appropriate and pleasant environment requires considerations from three aspects of economy, health, and comfort. Related with these are the productively optimal temperature, the physiologically optimal temperature, and the subjectively optimal temperature. While a human being makes subjective judgments on his or her environment through physiological reactions, the kinds of these subjective judgments include those on perception, evaluation, preference, receptivity, and permissibility. The subjective evaluation is measured by declaration of subjects. An evaluation method using a category scale or an SD scale is used for the measurement. The evaluation on cold-hot feeling and comfort using the category scale and that using the SD scale are explained, whereas the evaluation on preference relative to environmental temperatures is carried out by rating that the present environment should be made warmer'', can remain unchanged'' or should be made cooler''. 22 refs., 5 figs., 5 tabs.

    The present status of surveillance and research on acid fog is reviewed. Acid fog is usually gathered by automatic active fog water collector, and like acid rain, its pH, electro-conductivity and various ion species are measured. Radiation fog and upslope fog are frequently generated as polluted fog, and radiation fog as low as 2.25 in pH was observed in Los Angeles for example, indicating its ion species concentrations 10-100 times as high as those in usual rain. Acid fog as low as 3 in pH was also observed in the eastern mountains in the United States. In Japan, generation of aid fog is frequently observed at 4 points such as Akagisan, Tomakomai, Oyama and Sangunyama suggesting the relation between acid fog and plant damage, while human injury due to acid drizzle has been also found in the Shizuoka area and northern part of the Kanto Plain. In addition, the simulation of fog water oxidation is being conducted with a model based on both kinetics and equilibrium, indicating a good agreement with monitoring results. 33 refs., 9 figs., 4 tabs.

    In order to maintain reliability, performance and yield of large scale integrated circuits (LSI) at high level, heretofore the control of fine particles of impurities has mostly been done, and the size of the fine particle has been 1/10 of the minimum workable dimension of a device. However, in the present times that the minimum workable dimension of LSI has become less than 1 {mu} m, it becomes important to control heavy metal and impurities of molecular size in addition to the fine particles of impurities as used to be, and in order to achieve this, it is necessary to detect the existence of these impurities with high precision. In this article, these measurement evaluation techniques are put in order from the standpoint of a LSI processing engineer, and a rough explanation is given to the measurements of contamination on a wafer (the analytical method of extract and the total reflexion fluorescence X-ray method) as the methods of contamination measurement of heavy metal and molecules, the contamination measurement in the clean air, and the contamination measurement in high purity gas. In addition, with regard to the particulate contamination measurement, the particle measurement in gas and in fluid is introduced. 12 refs., 5 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.

    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.

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.

    This paper describes the technology development by which biomass is produced by treatment of pollutants using microalgae, and is recycled. A bioreactor system has been developed, in which microalgal biomass can be obtained through the effective treatment of CO2 and NOx using microalgae having ability of increase under the severe condition with simultaneous flow of CO2 and NOx. A new method has been also developed for separating and recovering the microalgae. Materials, such as glucose, glycerol, acetic acid, and lactic acid, were produced from the obtained biomass through physico-chemical and biological treatments. These materials can be converted into ethanol and hydrogen. For this treatment and recycling system, functions as a part of natural material recycling were considered to be most significant. Development of an analysis and evaluation method of an impact of this system on the natural environment is also tried. 1 fig.

    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 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.

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.

    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)

    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.

    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.

    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.

    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.

    Research and development have been pursued of plastic materials degradable in sea water and their application to the fishery material field in consideration of protection of the marine environment. Tests are conducted on degradation speed of bioplastics in sea water. Concerning a sample copolymeric polyester, by giving 4-hydroxy butyric acid, 1,4-butanediol, 1,6-hexanediol and {gamma}-a butyrolactone group to A.eutrophus, copolymeric polyester P (3HB-co-4HB), a mixture of molecular units of 3-hydroxybutyrate (3HB) and 4-hydroxybutyrate (4HB) is fermented. Test results show that it degrades at the same speed, being independent of molecular structures of biopolyester and copolymerization composition, different from the case of degradation in soil. It is clarified that the microorganism which degrades biopolyester in sea water is streptomyces, a kind of actinomycetes. 3 refs., 5 figs.

    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.

    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.

    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.

    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.

    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.

    Described herein are the results of the FY1994 research program for analysis and evaluation for thin-film compound semiconductor solar cells. The study on epitaxial growth and optical properties of the thin films of CuInSe2 and CuGaSe2 evaluates the thin epitaxial films grown under various conditions, showing morphology of the defects at the interface of heteroepitaxial growth. These results are used to set the growth conditions under which a thin film of high luminescence by exciter recombination is produced. The study also gives information of luminescence transition in the vicinity of the band ends and of energy level between the bands. The study on structural analysis of the epitaxially grown thin films of CuInSe2 investigates dependence of lattice constants of the MBE-grown CIS layer on film thickness by the X-ray diffractometry based on the bond method. The study on epitaxial growth by the Se(CH3)2-halogen transfer method tests epitaxial growth of the single-crystalline Mo on a substrate of single-crystalline sapphire. 5 figs.

    The paper described the flow of the standardization for EV use charge system and the inter-control with vehicles. Charge systems now used on the market are the inductive charge system and conductive charge system. The inductive charge system has no mechanical touches and is excellent in durability because the electromagnetic induction is used to the portion of power transmission. As to the standardization of the inductive charge system, it was found out that the construction of the world standards in the electric-wave use system is difficult, and the optical communication system was studied. At present, the work for revision has been proceeded with of the standards for the charge paddle (optical communication interface is adopted) which was reduced in size by about 40% of the conventional one. This charge paddle was made public at EVS15 in September 1998, and is being developed jointly with GM-Toyota. Around November 1999, the standards are expected to be formally revised. For the power control of the charger, the controller on the vehicle side transmits power request values. The rise in power request value is limited, so that the rapid power increase is avoided.

    The effect of added water on structural change in castor oil was studied by a hot wire method. The change in kinematic-viscosity coefficients for anhydrous and hydrous castor oil were measured to evaluate the interaction between water and castor oil molecules. The kinematic-viscosity coefficient gradually increases with increasing the water content and reaches the maximum value at 4075 ppm of water. However, with the further increase in water, the kinematic-viscosity coefficient sharply decreases due to the destruction in the liquid structure of castor oil. Eventually, the maximum value is attained at the solubility limit of water in oil. The ratio of the number of hydroxy groups of glycerol triricinoleate in the castor oil to the amount of water molecule is 5/mol H{sub 2}O at the maximum kinematic-viscosity coefficient, where the liquid structure is developed due to the intermolecular crosslinking of water. However, the crosslinking of water disappears at the solubility limit of water and a water cluster is formed. In this case, water acts as a kind of a plasticizer decreases the kinematic-viscosity coefficient. The liquid structure is gradually destroyed at each water content with the rise in temperature from 10 to 50 degree C and it almost disappears at 60 degree C. (author)

    Lifting phenomena caused by vortex-flame interactions have been investigated about diluted propane jet diffusion flames forced by a speaker installed at the bottom of a fuel tube. Open let diffusion flames were formed on a co-flow burner composed of the inner fuel tube and an outer air tube. Two type nozzles of rim thickness of 1mm and 0.2mm were set at the end of the fuel tube for each experiment and the effects of the rim thickness on the flame stability were investigated. Artificial vortices were imposed in the fuel flow through the speaker excitation to make clear vortex flame interactions. The schlieren and OH radical imaging techniques were employed to unveil the interactions. Experiments in terms of the difference of rim thickness revealed that the ratio of the rim thickness to the Quenching distance is important for lifting criteria as proposed by Takahashi and Schmoll, because the ratio of unity determines the limitation of whether the end of the flame base being in or out the recirculation zone behind the rim. Moreover, it revealed that the vortex-flame interactions are able to become the trigger of lifting, though the effect to lifting was questionable so far. (author)

    Wide-band POF covering Gbps as a Japan-made R and D fruit will be commercialized in the near future. It is very important to make an international standard specification for the transmission by the aid of the wide-band POF, which would be basically the standard for the future home networks. The efforts in this year were directed to finding the optimum parameters for widening the band, for which the necessary characteristics related to, e.g., transmission band and bending loss were measured and evaluated, and the specifications covering a certain range were established. The wide POF system is considered to provide the first chance of the optical transmission systems going into homes on a large scale, and the service conditions and regulations for use in homes have been comprehensively studied. These efforts have begun with collection of the measured data in consideration of operating optical elements represented by LD's, their peripheral circuits and the transmitter/receiver assemblies in which they are mounted at S400 or more. Each of the light emitting and receiving sections, including their peripheral circuits, were measured and evaluated, where they were mainly operated at a short wavelength of 650 nm, which is the same as that for the DVD.

In this paper, combining with a Rankine source method, the SQCM (a simple panel method) is applied to the unsymmetrical flow problem around catamarans. And the running attitude of the model is not fixed in both the calculation and the experiments. Comparing with the experiment we show the interaction between hulls and the hydrofoils for the lift and the wave-making resistance in the high speed range. 6 refs., 11 figs.

    Since an phenomenon was found out that NOx emission, which was thought to be increased, will be decreased by burning the high temperature preheated air jetting it at high speed (high temperature air combustion) in industrial furnace, there appeared a possibility of technical breakthrough for achieving the heightening of energy utilization efficiency and NOx reduction by exhaust heat recovery at the same time. This project aims at conducting full-scale experiments based on the basement technology including the theoretical elucidation of the combustion mechanism and high temperature air combustion by using various experimental facilities. Further, making full use of the most up-to-date analysis methods and constructing general-purpose database, the development is also aimed at of high performance industrial furnaces such as various heating furnace, heat treat furnace and melting furnace, with the assumption of prompt commercialization of the results of the development. As a result, targets were achieved such as energy saving of 30% or more, downsizing of 20% and a remarkable NOx reduction. Core technologies of this project are in-system limit heat recovery technology, high temperature air combustion technology, temperature field control technology (furnace temperature leveling technology) and high exergy heat transfer technology (furnace temperature heightening technology).

    This paper elucidated correlations of pedestrian leg and pelvis injuries, and made a proposal, based on the leg injury occurrence mechanism, on the specifications for leg impacter used in the pedestrian leg protection testing method presently discussed in EEVC. In the analysis, using the pedestrian injury information database of 316 pedestrians owned by the U.K.' Major Trauma Outcome Study, the occurrence ratio of leg, pelvis and thigh of pedestrians was examined limiting the level of thigh injury to bone fracture. As the result of studying correlations between leg injury and pelvis injury, the pelvis or the thigh tends not to break in case tibia breaks, and the trend is markedly seen in case both tibia and fibula break. As to correlations between injuries at legs, there appear no bone fractures of knee joints and ankles in case tibia breaks. Accordingly, the paper made a proposal that the specifications for leg impacter should be provided with the structure by which the tibia fracture can reappear. (NEDO)

    For the advanced utilization of casting iron, temperature differential austempering and partial austempering with the gradient mechanical properties of ADI (austempered ductile iron) by local electric method were experimentally investigated. For the former, gradient mechanical properties are obtained by giving temperature difference to the material in the process of austempering of casting iron, to add the strength and toughness. For the latter, mechanical properties are controlled by repeating partial austempering with changing the isothermal transformation condition by means of local electric method, to obtain the strength characteristics with appropriate balance. As a result of the former experiment, function gradient materials could be obtained with continuously changing internal mechanical properties. The fabricated material provided different properties depending on the direction of load. Radial crushing strength constant of the ring material depended on the treatment temperature of inside surface of the specimen. Fatigue and yield strengths can be simultaneously improved. As a result of the latter experiment, it was found that the mechanical properties can be improved at arbitrary part by the partial austempering. 13 refs., 25 figs., 4 tabs.

    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.

    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.

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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    Aiming at detecting nondestructively underground cavities, metal pipes or constructions that are buried underground deeper than meters, several kinds of subsurface radar are developed. But, as to targets with electric characteristics similar to surrounding materials, it is impossible to detect them simply by only using the method that compares the sizes of the amplitudes of the reflection waves so as to detect such materials as metal pipes. In the present paper, based on introducing statistical variance, it is clarified that such targets with electric characteristics similar to surrounding materials as underground cavity may be detected by the subsurface radar. The statistical variance is calculated by cell of the Log/CFAR processing, the size of the cells in question at that time may be selected according to times of length of the cells in depth direction and the number of the data in scan direction has no effects on it. The relation between the variance of the sample experiment data and the underground structures present is investigated and the connection to the underground structures is explained, based on the results of field experiments. 8 refs., 8 figs., 3 tabs.

    This paper describes the result of evaluation made on oxidiazole derivatives, which have been used as materials for electrophotography and scintillators, as a new organic electroluminescence (EL) material. The evaluation made on 10 kinds of newly synthesized oxadiazole derivatives gives the following results. When various substituents having different electronic properties are introduced into three types of oxadiazole derivatives, A, B, and C, strong fluorescence from 374 nm to 527 nm in wavelength occurs. Regarding the wavelength difference between the photoluminescence (PL) and EL, those having substituents of alkyl, ethoxyl, and phenyl groups have larger wavelength differences and those having substituents of dimethylamino base have smaller wavelength differences. As a result of investigation on luminance characteristics made by device structures, it becomes clear that the groups having larger wavelength differences between EL and PL are substances having only electron transporting property and groups having smaller wavelength differences are substances having both electron and hole transporting properties. 9 refs., 12 figs., 1 tab.

    The purpose of this study is to evaluate the correlation between the viability of milliscale biological materials and their effective thermal conductivity during extracellular freezing in order to achieve successful cryopreservation. The killifish embryo (Oryzias latipes, orange-red variety {phi}1.3mm sphere) was employed as a sample biological material and the viability was evaluated by the hatching rate. Dimethylsulfoxide-water was selected as the cryoprotectant. The thermal conductivity was measured using a self-heated thermistor technique developed by T.A. Balasubramaniam (1977). The thermistor ({phi}2.5 mm sphere) was installed at the bottom of a test section 8{times}8{times}12 mm, and exposed to biological material. The cooling system was equipped with Peltier devices and was capable of reducing the temperature of the test section to -30{degree}C. Between 150 and 200 embryos were loaded in the test section with 5, 15 and 20% w/w Dimethylsulfoxide-water. The effective thermal conductivity during extra cellular freezing was measured over the temperature range -20 to 6{degree}C with a cooling rate of 0.1 to 10{degree}C/min. The effective thermal conductivity increased from 0.5 to 1 W/(m{center_dot}K) with decreasing temperature and increasing the cooling rate. The decrease in the hatching rate and the variation in the effective thermal conductivity were correlated. Thus the viability could be controlled using their effective thermal conductivity during the extra cellular freezing. 23 refs., 12 figs., 2 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.

    This paper enumerates different kinds of substances that are believed to cause cancer, and discusses how they behave in their quantitative evaluation on carcinogenic effects in human bodies. About 600 carcinogenic substances have been discovered from experimental animals, of which about 50 substances have been identified to clearly cause human cancer. The quantitative risk evaluation is performed by combining mainly two items; information of intensities of carcinogenic effects and human intake of the substances. An amount of a substance that raises a carcinogenic frequency by as much as a one million fraction when lifetime experimental animals are dosed with the substance is called a virtually safe dosage (VSD). According to calculations, the amount of BHA, a food additive for example, that is taken by Japanese people from different kinds of oils is 1/70 of the VSD, a very small contribution to occurrences of human cancer. Carcinogenic substances cannot explain, with very few exceptions, the occurrence of human cancer quantitatively. Living practices should rather be changed and improved. 5 refs.

    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 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.

    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 fatigue crack growth tests of WC-Co Cemented Carbides were carried out in a wide range of fatigue crack growth rate covering the threshold stress intensity factor range {Delta} Kth. The effects of the stress ratio, Co volume fraction and the phase transformation of Co on the fatigue crack growth characteristics were investigated on the basis of fracture mechanics and fractography. The crack growth rate was measured using 3-point bending specimens. Crack growth tests were carried out at 10 HZ and the stress ratio R=0.1 and 0.5. The main results obtained are as follows; (1) The Paris rule can be applied between da/dN and{Delta}K and it is shown to be da/dN=C({Delta}K){sup m}. (2) The fractography of the fracture surface, shows that brittle fracture occurs in the Co binder phase at the stress rate R = 0.1 but ductile fracture occurs in the Co binder phase at R= 0.5. (3) The relation of da/dn-{Delta}Keff / E of WC-Co cemented carbides shows the characteristic in the middle of the other metals and the alumina ceramics. (4) The Co binder phase undergoes phase transformation by repeated deformation and so it affects the characteristics delicately. 22 refs., 9 figs., 3 tabs.

    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)

    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.

    To grasp dynamic cardiac function physiologically and biochemically before, during and after the wheelchair marathon for physically handicapped persons, the safety of athletic sports rapidly diffused for physically handicapped persons and the significance of cooperation among health, medical treatment and welfare are medically evaluated. There were no changes on the echocardiogram. Decrease in left ventricular function, which was observed in the triathlon race, was not recognized. From the results of biochemical test of blood, no damages of cardiac muscle were suggested. The findings of dehydration, which were anticipated in the biochemical test of blood, were not recognized after the race. It was suggested that stricter prevention of atherosclerosis, such as sufficient supply of water, is required for older persons. It is possible that these subjects who have hardly atherosclerosis, if they enter the race after full training and with supplying water, do safely without the bad influence to the heart. 9 refs., 8 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.

    This paper describes the design of high-speed cellular array divider with selection function suitable for VLSI. Although dividers have not been used practically, a high-speed divider is required in real-time applications of digital signal processing and robot control. The present divider uses new techniques which can deal with both fixed-point and negative operands and can generate in parallel both a quotient bit of one row and a partial remainder and CLA bit of its next row. Moreover, the delay time of the proposed divider is calculated in terms of a unit gate delay. Using PARTHENON, a VLSI design system developed by NTT, VLSI evaluation of the proposed divider was conducted. As a result, elimination of delay time for even rows became possible, when the generation time of partial remainder and CLA signals was reduced. Thus, the delay time can be reduced by approximately one-half of the formerly proposed dividers. From the evaluation result of PARTHENON, the power consumption and gates were less than two times. 10 refs., 5 figs.

    Air cooling characteristics were studied on heat generating resistors simulating IC elements on a substrate, which were arranged in three lines by five rows in a vertical and square flow path, to identify cooling air flow and thermal conduction to remove heat generated in an IC package constituting electronic components. Surface temperatures of the IC simulating heat generating resistors were measured by means of thermography through a thermo couple and permeation film, and so were the steady and non-steady temperature distributions. Experiments were conducted varying the flow rate associated with natural convection and forced convection, as well as the input voltage (heat generating input is given to the heat generating resistors). The relation between the Nusselt count and Reynolds count in the forced convection agreed nearly with the Maffat equation relating to a thermal element. The relation between the Nusselt count and the Rayleigh count in the natural convection agreed nearly with the Aihara equation, showing the values given on its curve. The cooling fin efficiency is approximately 0.69, which agreed with the theoretical analysis. 5 refs., 26 figs., 4 tabs.

    Superconductive technologies are introduced into electric power devices for attempts of achieving higher stabilization, density and efficiency, as well as size and weight reduction and improvement in performance of the devices. The project has been worked on since fiscal 1998 as part of the New Sunshine Project. Fiscal 1998 being the eleventh year has taken the following subjects as the research promotion policies: establishment of plans targeted at accomplishment of the goals of the project; adequate and reliable implementation of verification of technological assignments; and steady and efficient demonstration tests. Subsequent to the previous year during which site demonstration tests were completed on a low-speed responsive model machine, the site demonstration test has begun on the ultra high-speed responsive model machine as the final stage of the project. The ultra high-speed responsive model machine was coupled with a freezing system and a load synchronizing machine, and different kinds of test were carried out where good results were obtained. Researches were conducted on characteristics improvement and device element technologies aimed at achieving the practical application level by utilizing the respective features of AC metal-based wires and oxide-based wires, where sound results were obtained. Also in an improved freezing system, valuable data were attained as part of establishing the basic technologies for a superconductive power generation system. (NEDO)

    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.

    This paper proposes the small portable type power source `WISH BOX` (wind and solar hybrid) composed of a small wind power generator and solar cell panels. Since solar radiation and wind power are complementary to each other in seasons, day and night, and fine and cloudy weather, WISH BOX is useful for standalone power source in non-power areas of developing countries, life spot in disasters, and outdoor leisure.

    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.

    A survey was made on autonomous responsive materials as a new material which reversibly change molecular structures and the aggregation state according to external stimuli. Autonomous responsive materials imitate environmental responsibility in the living organism system and have sensing, control and active functions for external stimuli. The materials are highly efficient and environmentally friendly. In biomimetic materials for soft actuators, drastic changes by temperature of elastic modulus of water-swollen hydrogel are used to the motion. In order to molecularly design stimulus-responsible polymer gel, studied are the relation between the micro structure and stimulus responsibility, dynamic correlation between the micro structure and the macro structure, etc. In the biomedical field, new cure and diagnosis using innovative materials are expected, and the application of autonomous responsive materials to the field is studied. For example, using hydrogel responding the temperature and the surface and controlling by temperature the interaction with components of the organism such as protein and cells, drug delivery in the organism is optimized.

    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.

    Various energy-related issues were analyzed in a many-sided and compound manner; and as their solutions, various combined systems were examined on the assumption that functional mediums, core technology and regional district characteristics were utilized; and an explanation was given in the case of using hydrogen as an energy medium. Hydrogen was a strong candidate capable of securing toughness in energy flow; and an idea was shaped about introducing hydrogen by steps before structuring a hydrogen society that is to replace the petroleum society. In the case of introducing a hydrogen energy medium into an intelligent building, the characteristics would be such that it is a highly efficient system capable of supplying energy in the form of electric power, hydrogen and heat, that it brings in a function for leveling a load of electric power, that it facilitates consistency with each energy in various uses, and that it is capable of dealing with a demand for hydrogen energy which is expected to increase in the future.

    In order to inspect, by an external diagnosis, the buried pipeline in degree of corrosion, buried pipeline corrosion diagnosis method without excavation was investigated and studied. Electric probe current measurement method, selected as a diagnosis method without excavation, taking into consideration the diagnosis in accurateness, operability, etc., was studied in possibility of adoption to the buried pipeline diagnosis in yard of substation. Upon comparison between the detection data by pipe-locator and actually confirmed pipeline location, the measurement accuracy was within plus/minus 10% in both location and depth, which confirmed the detection not to be problematic. Diagnostic measurement by micro-cell tester and 1-m sampling of buried pipeline at spot of that measurement were followed by obtaining the actually measured value of corrosion. As a result of investigating correlation between both the diagnosed (H) and actually measured (D) values of the maximum corrosion in respectively each substation, the dispersion value was small with the lowest number of dispersions among those substations, in case of corrosion, less than 0.5mm in depth, in which case the synthesis of correlative linear lines was D to be nearly equal to H with an indicated appropriateness of diagnosis method. 3 refs., 8 figs., 4 tabs.

    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.

    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.

    The paper investigates and reports problems on plastic waste and measures to solve them, and the developmental trend of main biodegradable plastics in the world. A large quantity of plastic waste neither rots nor returns to the nature even if reclaimed. The recycling system has not yet been established due to its low price. Therefore, countries are carrying out regulations on prohibition on the use of foamed polystyrene, compulsory use of degradable plastics, taxation on plastic bottles, etc. Among biodegradable plastics, a type of polyethylene blended with starch is legislated for its use in the U.S., but is met with opposition by environmental organizations because of its plastic powder remaining in the soil. Contrary to this partial degradability, the following are cited as completely degradable plastics: bioplastics based on microorganism, natural polymer based on plants and animals, and biodegradable synthetic polymer. Any of them, however, is still in the stages of research/development and commercialization. 376 refs., 28 figs., 37 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.

    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.

    The basic theory of the proficient machine system to be developed was studied. Important proficient techniques in manufacturing industries are becoming extinct because of insufficient succession to next generation. The proficient machine system was proposed to cope with such situation. This machine system includes the mechanism for progress and evolution of techniques and sensibilities to be adaptable to environmental changes by learning and recognizing various motions such as work and process. Consequently, the basic research fields are composed of thought, learning, perception and action. This machine requires not only deigned fixed functions but also introduction of the same proficient concept as human being to be adaptable to changes in situation, purpose, time and machine`s complexity.

    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)

    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 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.

    Basic research of biological measures for which the accumulation of basic findings is mandatory and the applied research of chemical and physical measures that are higher in feasibility are conducted for the establishment of measures to counter freshwater red tides. In the basic research, natural enemies, algaecidal microbes, conjugation inhibiting substances, and allelopathy are studied, but none of them is found feasible at the current stage. In the basic research, however, factors are discovered that inhibit the multiplication of Peridinium bipes or perish the same. In the applied research, chemical algaecidal methods, UV-aided algaecidal methods, and various red-tide constituent collection methods are studied. Collection methods are compared, and it is concluded that a method of Toray Industries, Inc., efficiently collects red-tide constituents. In this method, red-tide constituents are screened by and condensed on a cloth filter provided on the internal wall of a drum, and are dehydrated and then transferred. The applied research further involves the prediction of red tide outbreak and the raising of fish on a food containing substances extracted from red tides, and it is suggested that these are feasible. 18 refs., 15 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.

    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.

    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.

    Because the succession of techniques requiring proficient technologies is becoming difficult year by year, the proficient machine system was proposed. Most of such techniques are dependent on intuition or experience difficult to express numerically, and also require flexible adaptation to work conditions. The above system was studied theoretically to realize acquisition of techniques and adaptation to situation changes (cf. the theoretical part). Seven important proficient works with strong industrial need and social impact were selected, and in addition, these were restricted for four fields such as maintenance, machinery, testing/adjustment and welfare industries. The proficient machine featured by self-progress and evolution of abilities was studied in three stages such as execution of only translated works, establishing of optimum combination of functions with procedures, and automatic construction of new works. The learning method of robots, the mechanism of adaptive process for system proficiency, and feedback system were studied as approaches. Bio-actuator was also studied as elemental technology. 10 refs., 30 figs., 10 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.

    The technology trend was surveyed to clarify the themes of smart structural system towards its R and D. 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.

    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 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.

    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. The residual resistance ratio was found to be 200, showing sufficiently high value, and sufficient function was verified in the stabilized copper.

    Weatherability tests such as exposure to the atmosphere are conducted to collect and accumulate information on the degradation of house-use photovoltaic equipment expected to come into use in areas where weather conditions are hostile. Based on the thus collected data, analysis and evaluation are conducted about the mechanisms of corrosion and degradation for the establishment of designing and evaluating methods for maintaining weatherability. Since fiscal 1994 is the first year of the project, preparations are made for tests to be conducted. In carrying out research activities, a Weatherability Evaluation Committee for House-Use Solar Light Electric Power Generating System Equipment is organized, who discuss implementation of the project. Discussion is made on the shape and structural materials of the exposure rack. An aluminum alloy coated with a clear coating of alumite sulfate is selected, and a rack is built. Specifications of a sea salt particle collector are discussed, and preparations are made for arresting and quantifying sea salt particles under the Japanese Industrial Standard (JIS) dry gauze method and the International Organization for Standardization (ISO) wet candle method.

    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.

    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 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.

    As part of the geothermal development promotion survey, the comprehensive analysis was made on the survey of the existence amount of geothermal resource in the Akinomiya area, Ogachi town, Akita prefecture, which was conducted in FY 1999. In the evaluation of reservoirs, the following were carried out: comprehensive analysis of various data on the surface survey, well exploration, etc., which were stored in surveys from the primary to the forth, modification/construction of geothermal system models, numerical simulation using 3D models, etc. In the long-term jetting test, production/reduction tests were conducted using N9-AY-3 and N10-AY-8 as production wells and N8-AY-1 and N10-AY-6 as reduction wells. The results of the comprehensive analysis were outlined as follows. The distribution of high temperature zones promising as areas for geothermal development was grasped. The distribution of the main fracture structure underground was grasped. A total amount of 124t/h steam was confirmed by short/long term jetting tests. In the simulation of prediction of production, the result was obtained that there was potential power generation of 30MW in the Akinomiya area alone and 60MW both in the Akinomiya area and the Wasabizawa area.

    The geothermal development promotion survey was conducted in the Akinomiya area, Ogachi county, Akita prefecture, and the FY 1998 results were summed up. In the surface survey, geology/electromagnetism/precision gravity survey was made as supplementary survey, and re-analysis of 3D models was made. In the well survey, three wells of N10-AY-6 to N10-AY-8 were drilled to conduct the core examination, temperature/pressure logging, sampler logging, short-term jetting test, etc. Also conducted were the reservoir evaluation, environmental effect survey, etc. by pressure monitoring and water level observation. The results of the comprehensive analysis predict the following. In the Akinomiya area, there exists heat source in deep parts around Mt. Yamabushi-dake and Mt. Takamatsu-dake; Being given heat from this heat source, rocks, ground water and volcanic gas react on each other to form geothermal fluids. It is presumed that high temperature geothermal reservoirs exist in the east of the area. Moreover, the pressure distribution indicates that the Akinomiya reservoir and Wasabizawa reservoir can be a chain hydraulically. On the other hand, the west of the area is the low temperature and heat conductive area, and therefore, there seem to be no high temperature fluids there. (NEDO)

    The paper reported the energy situation in Thailand, the present and future status of coal supply/demand, the present situation of environmental policy and air pollution prevention policy and problems concerning coal and the measures for solution, and a possibility of Japan`s cooperation. In Thailand, the total coal supply amount in 1992 is 16.079 million tons, which is 9.1% of all the primary energy supply amount. The country produces only a few amount of anthracite and subbituminous coal beside brown coal. The domestic coal equals brown coal, the production of which was 15.335 million tons in 1992, 13.9% of all the primary energy demand. Concerning brown coal, 79.7% of all the brown coal supply are for electric power use, and others for industrial use such as the cement industry. The remaining reserve in developed areas is 151.4 billion tons, and the proven reserve in undeveloped areas 756 million tons. The demand for import coal was 11.25 million tons in 1996, and is expected to be 201.73 million tons in 2000. The paper pointed out some problems arising from coal production and spread of coal utilization, and described measures to solve the problems and fields where there are possibilities of Japan`s cooperation. 36 refs., 44 figs., 73 tabs.

    Survey was made mainly on use of biotechnology as resource saving and energy saving processes. Biotechnology is in wide use in a pharmaceutical field, while its application is on the increase in agriculture, food, chemistry, energy and environment fields. The USA is ahead of Japan and Europe. In the USA, there are more than 1000 ventures, and R and D of biotechnology, in particular, gene analysis and manipulation techniques are in progress together with acquisition of patents. In biomass energy, production of ethanol from corn, and development of biodiesel are in progress in the USA and Europe, respectively. Use of biomass should be promoted because of its global environment compatibility and sustainable productivity. In the future bio-market, genome analysis and its application are most important, however, Japan is behind in such technology in the world. The Joint approach by industry, university and government is necessary from the viewpoint of a future marketability and international competitiveness. Promotion of a public acceptance and nurture of creative talents are also important. (NEDO)

    The R and D program is implemented for permanent magnet, as part of the project aimed at commercialization of a 10 MWh-class high-temperature superconducting magnetic bearing type power storage system. A speed of rotation of 28,570 rpm is attained by using an iron intermediate ring for a Pr permanent magnet rotator and reinforcing the rotator with a plastic hoop reinforced with carbon fibers three-fold (CFPR hoop). The speed is increased to 31,300 rpm by interlacing carbon fibers also in the radial direction and replacing iron for the intermediate ring by titanium. The highest speed of rotation of 33,506 rpm is realized by the rotator of permanent magnet of sintered Nd. The magnetic circuit of stronger, more smooth magnetic field needs the permanent magnet of less uneven magnetic flux. The magnet is of a monoaxially anisotropic rare-earth metal, with four-fold magnetic ring bodies having fan-shaped small pieces arranged on each ring. Uneven magnetic flux occurs at the joint between these small pieces. The one-body-ring magnet of radially anisotropic, sintered Nd is developed, and incorporated in the repulsion type magnetic circuit, to reduce unevenness of the magnetic flux. (NEDO)

    The permanent magnets have been investigated and developed, for eventual commercialization of a 10 MWh power storage system by high-temperature superconducting flywheel. The permanent magnet rotors have been already developed in the previous years using a praseodymium-based magnet (Pr magnet) and neodymium-based sintered magnet (Nd sintered magnet), and the target rotational speed of 30,000 rpm has been attained. For development of the magnetic circuit to produce a stronger and smoother magnetic field, magnetic flux density of the Nd sintered magnet is measured. It shows a lower magnetic flux irregularity than the Pd magnet, but there is still room for further improvement. For development of large-size permanent magnet fabrication techniques, it is confirmed that the large-size Nd sintered magnet can be easily magnetized by partial magnetizing, as is the case with the Pr magnet. In this year, the irregular magnetic flux is three-dimensionally simulated, based on the results obtained in the previous years, to find that the simulated results are in good agreement with the observed ones. The measures to solve the problems are also investigated. It is also confirmed that the large-size ring magnet can be easily magnetized by partial magnetization. (NEDO)

    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)

    The hardware which supports IT is composed of information processing (MPUs and memories), information communication (input/output and communication) and information storage as the three basic elements. This project studies development of the basic technologies for realization of tera-bit (1TB/in{sup 2}) class information storage, in order to cope with drastically increased volume of information as a result of progress of the IT revolution. An HDD (hard disk device) will be the sole device which can correspond to required large-capacity, high-speed storage. However, realization of the recording density for 1TB class storage needs materials and controlling technologies at the atomic and molecular levels, because all of the basic technologies therefor, e.g., those for recording medium, head device and positioning mechanisms, are characterized by nm-order technologies. In other words, it is important to promote the research and development activities for the technologies for three-dimensionally configuring/controlling the atoms, processing magnetic materials at the nm level, and superhigh-speed devices. The concerted efforts by the industrial, government and academic sectors are required for quickly realizing the technological breakthroughs, which need advanced processes based on new principles and development facilities.

    In Japan with its rapidly aging society, fundamental technologies are required for the development of artificial nerves substituting for or supporting damaged ones, and ultimately constituting artificial neurons based on the knowledge of the brain functions at the molecular and cellular levels. This study defines the fundamental technologies which would be required for the development in the area, and further, evaluates the potential of the technologies to develop the novel industry. The brain function is closely related to the activity in neuronal circuits. In order to repair injured nerves and to develop the advanced technologies of electronics for helping impaired neuronal functions, the most important and urgent is to understand how to work the neuronal circuit system in the brain. Based on these viewpoints, new methodological approaches would make it possible to relieve neural impairment in the sensory input system and the motor system by the use of electronic circuits. They also would improve rehabilitation after injury, and treat neurodegenerative diseases such as Parkinson`s disease. These advances surely create the new types of industry seeds in near future. 77 refs., 29 figs., 2 tabs.

    In order to find the higher critical strength, toughness and corrosion resistance of Al system materials than those obtained by conventional methods, crystal grain control was studied in a finer-grain region. The above characteristics of Al materials obtained by conventional technologies such as alloy element addition and heat treatment controlling crystal grains of several tens {mu}m are approaching critical values, resulting in poor characteristics for the latest needs. It has been confirmed experimentally in fundamental studies using small specimens that fine crystal grains of several {mu}m can remarkably enhance the above characteristics. Technology for creating mesoscopic structure-controlled materials was thus studied. In particular, creation of ultra-fine advanced Al alloy bulk materials by cryogenic processing method was selectively studied. The developmental approach and its issue were thus revealed for creating mesoscopic crystal structure by recovery and recrystallization of a highly distorted state obtained by cryogenic processing. 102 refs., 80 figs., 8 tabs.

    Discussing the rotor blades of the torsion arc blade type (TABT) wind turbine, difference in windmilling characteristics was determined between elliptic blades and rectangular blades by theoretical analysis and model experiment. Experimental generation of power was carried out using a test wind turbine in the natural wind. First, elliptic blades were bent into arcs and fixed to shaft. The action force was determined calculating the blade area and the wind velocity vertical thereto. Furthermore, the force in the direction to turn the rotor was determined with the effect of the part behind the blade taken into account. The rotation-curbing air resistance in the flank direction that a rotor experiences was subtracted to determine the torque generated. A formula was derived for the elliptic blade. Second, a formula was derived in the same way for the case of rectangular blades. In conclusion, in the case of 6-blade wind turbine, the rate of responsibility for wind turbine rotation of the part behind the blade was approximately 50% of the part in front of the blade. Shape coefficients were introduced into the theory, which resulted in values agreeing well with values obtained from experiments. Elliptic blades yielded more power than rectangular blades at the same wind velocity. High in durability, the TABT wind turbine is expected to be put into practical use as a compact auxiliary power generating device. 2 refs., 14 figs.

    In order to verify the complementary relationship between wind and solar energy, the long-term field test of the hybrid power system was conducted at the natural energy square of Ashikaga Institute of Technology. The solar cell blade windmill composed of a Savonius windmill and flexible solar cells applied to swept buckets was also prepared. As a result, the wind power generation was promising mainly in the winter period including the late fall and early spring, while solar one was stable all the year through although it was slightly poor in winter. Stable power generation was thus achieved by combining wind energy with solar energy. As the whole data of other wind and solar power generation systems at the square were analyzed for every month, the same conclusion as the solar cell blade windmill was obtained as follows: the wind power generation in Ashikaga area is promising in Nov.-March from the field test result for 16 months, solar power generation is stable all the year through, the hybrid power system is effective in Nov.-April, and the solar cell blade windmill is equivalent to the hybrid power system. 3 refs., 5 figs.

    To reduce fossil fuel consumption and CO2 emission, this article introduces an actually constructed natural energy autonomous house. It has a solar collector on the south roof for hot water supply and a sky radiator on the north roof for cooling water supply. The sky radiator uses radiation cooling phenomena into the space by electromagnetic wave through the window of atmosphere. This house also has an insulated tank with a capacity of 31 m{sup 3} in its underground. In the long-term heat storage mode, the heat is collected through the solar radiation during the period from summer to spring and is stored in the underground water tank, to use it for heating and hot water supply in winter. The heat can be recovered from the garbage waste incinerator. A gas fired auxiliary boiler is used for the shortage. In the long-term heat regeneration mode, the heat is regenerated through the sky radiator during the period from spring to summer and is stored in the underground water tank, to use it for cooling in summer. For the shortage, the water is cooled using a heat pump operated by the midnight power. The insulating performance is improved by using the pair glass in windows and the glass wool in the walls. Rain water is collected in a tank with a capacity of 2 m{sup 3}, to use it for toilet water. Annual energy and water saving is equivalent to 600,000 yen. 10 refs., 10 figs., 2 tabs.

    Study was made of an ice-on-coil heat storage tank for power load levelling. Prior to the prediction of performance of the system as a whole, the performance of the heat storage tank itself needs to be predicted. A brine (35.9% water solution of ethylene glycol) cooled by a refrigerating machine was poured from the upper end of the piping in the heat storage tank (consisting of 19 spiral pipes or coils arranged in parallel in the vertical direction) for the collection of ice around the coils. Ice grew thicker with the passage of time but there was no remarkable decrease in the transfer of heat because there was an increase in the area of contact between ice and water, and the brine exit temperature remained constant over a prolonged period of time. There was a close agreement between experiment results and theoretical conclusions throughout the heat accumulation process, including changes with time in the thickness of ice on the coils, all pointing to the appropriateness of this analytical effort. To melt the ice, water was poured into the tank top at a predetermined rate. Water chilly at 2-4{degree}C was recovered at the tank bottom, stable in the amount produced. As for the use of spiral pipes for making ice, the laminar heat transfer rate in such pipes are supposed to be more than two times higher than that in straight pipes, and this was quite effective in accelerating heat transfer. 7 refs., 11 figs.

    For further improvement of iron system materials, supermetals with ultimate characteristics were researched. Since their strength and toughness have been improved with grain refinement by thermomechanical treatment, improvement of single-phase steel is nearly completed, and the study on ultra-fine multi-phase steel is indispensable. Bulky materials are also restrained from grain refinement because of the capability of existing processing facilities. Making a breakthrough in such restraint requires a challenge to high-speed rolling, repeated shear deformation and ultra-high strain rate process beyond conventional technologies. Further improvement of microstructure and dynamic characteristics requires other energies such as magnetism as well as mechanical energy. {gamma}-{alpha} phase transition important for structure control of steel materials is dependent on magnetism. The study on structure control and characteristics improvement under ferromagnetic field is essential in the future. Material improvement such as reduction of impurities and circulating elements, environmental measures, and mechanical alloying remain as issues to be studied. 224 refs., 176 figs., 18 tabs.

    With an objective to achieve higher efficiency, higher density, and higher stability in power systems, research and development has been performed on superconductor power generators. This paper summarizes the achievements thereof in fiscal 1999. A verification test was given on the rotor of an ultra high speed responding generator. In a sudden short circuit test using the different phase charging method, no anomalies were found such as quench generation and vibration changes, wherein the healthiness of the generator was verified. In the VVVF actuation test, knowledge was acquired on the actuation method when the ultra high speed responding generator is applied to a combined cycle plant. After the verification test has been completed, the disassembly inspections such as visual check and non-destructive test were performed. With regard to the vacuum leakage found in the rotor under very low temperatures, the causes were presumed and the countermeasures were discussed by observing the weld structures. In the design research, the conception design on the 200-MW pilot generator was reviewed by reflecting the results of the verification tests on the model generator. At the same time, trial design was made on a 600-MW target generator. In summarizing the overall research achievements, the achievements and evaluations were summarized on technological issues that have been allotted to each research member. (NEDO)

    This report refers, continuously to the Part 1, to the in-situ verification test of the slow-response type model machine rotor and to the review of the conceptual design of the pilot machine. On the basis of the R and D results of various element technology/partial models obtained before the previous fiscal year, the design, manufacturing and factory test had been conducted for a 70,000kW class slow-response type model machine rotor. This year, an in-situ verification test was performed to complete the test of all planned test items. Using the technological results obtained in the design, manufacturing and test of the 70,000kW class model machine, the conceptual design is being reviewed of the 200,000kW class pilot machine. In the aspect of the functional design, accurate grasping of the thermal load is essential for the purpose of attaining a large capacity for a superconducting generator, as a part of which a thermal load analytical method was planned to be established for a torque tube heat exchanger. The reasonableness of the analysis was verified through a comparison with the factory test result of the 70,000kW class slow-response type rotor, indicating good agreement between the calculation result and the actual measurement, and enabling the result to be obtained that explains dependency of the thermal load on the number of revolution.

    Research and development is carried out to help aged people get employed in manufacturing industries. Important problems to solve before they can work in the field of fabrication or assembling involve deterioration in working environment recognition capability due to poor eyesight, reduction in work efficiency due to muscular weakness, and degradation in work precision due to quivering fingers, all these attributable to disfunction typical of advanced age. Accordingly, it is deemed that experienced old people's skill will be fully made use of if their deteriorated sensing and manipulating capabilities are mechanically supplemented. In this research, basic studies are conducted concerning a workpiece position/attitude recognition system for supplementing poor eyesight and an operation type manipulator capable of providing the sense of force. In the study of the recognition system, a method is considered, in which the selection of the necessary workpiece is dependent on the worker' ability and the position/attitude of the selected workpiece is measured by a sensor. In the study of the manipulator, a method is considered, in which the handling of the workpiece is performed by a manipulator similar in structure to that of an industrial robot and an active joystick is used to indirectly handle the workpiece. In fiscal 1998, designing and tentative fabrication are launched. (NEDO)

    Creation of new functional organic materials for the medical application has been investigated under the microgravity. Facilities of the Japan Microgravity Center were used for this study. For the high-speed synthesis of uniform polymer particles under the microgravity condition for ten seconds, appropriately good results were obtained in the oxidation polymerization of pyrroles. For the synthesis of organic conductive thin films by the electrolytic polymerization, the resistance of electrolyte became larger in the microgravity field. It was required to set conditions so as to enhance the effects of microgravity environment. For the orientation control and thin film formation of proteins, the bacteriorhodopsin was examined. It was found that the microgravity improved the quality of electrocoatings. When the surface tension and viscosity of coating liquid were appropriately controlled under the microgravity, thin films were able to be prepared by utilizing a change from 1g to {mu}g. When the high viscosity fluid is placed in the artificial two-dimensional space composing of two parallel plates, and the low viscosity fluid, such as air, is injected into the above, the interface grows in the finger shaped pattern, namely, viscous fingering. The influence of gravity on this phenomenon was also investigated. 11 refs., 45 figs., 5 tabs.

    A study is made for the elucidation of the effect of microgravity on biofunctions. The protoplast of shiitake is exposed to microgravity and then cultured, and a significant difference occurs. The rate of colony formation by cell fusion in the test sector is found to be two times higher than that in the control sector. When swimming ciliates which are unicellular are suddenly exposed to microgravity, their swimming speeds changed differently according to the direction of swimming. When a mouse subjected to acupuncture for three days is exposed to microgravity, its water metabolism and excretory function are enhanced. A mouse treated with Chinese medicine reacts in the similar way. The change due to microgravity in the amount of acetylcholine in the hypothalamus is found characteristically time dependent. Mice infected with lethal herpes viruses just after exposure to microgravity die at a rate in proportion to the number of exposures and to the amount of viruses given. The migration speed of chemical stripes in case of a gel-base BZ (Belousov-Zhabotinsky) reaction under microgravity is equal to that on the ground. The trigger wave migration speed in case of a water solution-base BZ reaction under microgravity is reduced to approximately 80% of the speed on the ground. 12 refs., 31 figs., 3 tabs.

    With respect to concept of resolution in seismic exploration using the reflection method, detailed considerations were given on processes of forming the resolution as a result of arranging observation points at vibration transmitting and receiving points. In the discussion, numerical experiments were carried out, in which the scattering stacking process is applied in a model having one scatterer existing in homogeneous media. The experiments investigated an imaging formation process of the scatterer when arrangement of the vibration transmitting and receiving points were changed from a coarse condition to a dense condition while the number of transmitting and receiving points is being increased. Resolution is created if waveforms having finite frequencies are used as input, and the imaging is performed by utilizing the limited number of vibration receiving and transmitting points. If the concept of equi-travel plane is used under these conditions, the equi-travel planes perform negation with each other, and it was indicated that visual resolution is expressed by how good the negating effect is. It was discovered that such concept of the resolution is quite ambiguous in terms of engineerings. 2 refs., 17 figs.

    With an objective to develop an airborne electromagnetic survey method for greater depths achievable of exploration, a discussion was given on an exploration method of a type in which a transmitting device is placed on the ground to receive signals in an atmosphere. A prototype exploration apparatus is mounted with a fluxgate magnetometer, an attitude meter, a GPS, and a battery. This exploration apparatus is suspended on a 30 meter long rope from a helicopter to perform the exploration. Two flight tests on this apparatus were carried out in the Unzen area, Nagasaki Prefecture and the Motomiya area, Wakayama Prefecture. The ground source was extended to a distance of 1.5 km, and a current of about 20 A was flown with a quiescent wave having four-second cycles. The helicopter flew nearly horizontally at a ground speed of about 50 km, a flight altitude of 450 m above sea level, and a terrain clearances of 100 to 400 m. The obtained data had variations in correspondence with changes in roll and pitch angles, whereas the variation of about 5000 nT was reduced to about 1000 nT as a result of correction. It was not possible, however, to correct completely the variation with short cycles, requiring further discussions on frequency characteristics of the magnetometer. 6 figs., 1 tab.

    Development of nenroactive materials to improve neuronal defects is one of the most important subjects in Japan that will soon become a aging society. In this project, basic research for neuroactive molecule was performed to develop technology for neuronal regeneration, regulation of synaptic activity and interface between artificial surface and living neurons. A novel neurite promoting factor was discovered and its cDNA was cloned. Mutagenesis in vitro showed that a functional region of this factor located in a polypeptide of less than 50 aminoacids. Using neuronal culture, synapse formation was found to depend on two modes of activities and long-lasting synaptic potentiation was demonstrated to depend on a macromolecules released from pre- or postsynaptic neurons. To regulate nervous activities, photoactivated caged-peptide was developed and confirmed to change in affinity to its receptor. Neurons were cultured on substrates paterned by microlithography.

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

    Basic studies are conducted for the collection of methane from the methane hydrate that exists at levels deeper than 500m in the sea. The relationship between the hydrate generation mechanism and water cluster structure is examined by use of mass spectronomy. It is found that, among the stable liquid phase clusters, the (H2O)21H{sup +} cluster is the most stable. Stable hydrate clusters are in presence in quantities, and participate in the formation of hydrate crystal nuclei. For the elucidation of the nucleus formation mechanism, a kinetic simulation is conducted of molecules in the cohesion system consisting of water and methane molecules. Water molecules that array near methane molecules at the normal pressure is disarrayed under a higher pressure for rearray into a hydrate structure. Hydrate formation and breakdown in the three-phase equilibrium state of H2O, CH4, and CO2 at a low temperature and high pressure are tested, which discloses that supercooling is required for formation, that it is possible to extract CH4 first for replacement by guest molecule CO2 since CO2 is stabler than CH4 at a lower pressure or higher temperature, and that formation is easier to take place when the grain diameter is larger at the formation point since larger grain diameters result in a higher formation temperature. 3 figs.

    Study was made for grasping the basic data of CO2 fixation technology by seaweed. The photosynthesis under the sea, which is different from that on the land, is judged to be made by taking in HCO3[sup -] and converting it into CO2 inside the plant. Porphyra yezoensis which is seaweed is cultivated as comestible. With a rise in CO2 content, the growth in length of leaves was observed to be accelerated through ventilating Porphyra yezoensis with the three test types of air which respectively contained 350ppm (atmospheric CO2 content), 1000ppm and 1600ppm CO2. As a result of measuring the photosynthesis speed by the generated quantity of O2, it was heightened with a rise in dissolved inorganic carbonic acid content of the sea water. Measurement was also made of daily fluctuation in calcification speed by Corallina officinalis capable of calcification by ventilating it with 350ppm and 1600ppm CO2. In case of 1600ppm, the sedimentation of CaCO3 was prevented. In case of 350ppm, the sedimentation was quantitatively larger during the bright period than that during the dark period. The growth of Gracilaria gigas which is an agar material was compared by changing the above CO2 levels. In case of 1600ppm, the weight grew to 2.3 times in 20 days. 16 figs., 2 tabs.

    The effective use of water-bloom was studied by component analysis of water-bloom. The component analysis was carried out using the algae body obtained by separation and cultivation of Microcystis from collected water-bloom from a reservoir. The analysis result showed such components as crude protein of nearly 64%, Phycosyanin of nearly 2% as blue pigment, nitrogen, phosphorus and potassium. As the effective use of water-bloom, extraction and purification of blue pigment, and composting of the algae body obtained from collected natural water-bloom were tested. The test result showed that purified Phycosyanin obtained by extraction from cultivated algae body of Microcystis aeruginosa is equivalent or superior to commercially available pigment products. The compost nearly satisfying the recommended standard of `Research Committee on Quality Control of Manure` was also obtained from collected water-bloom in a test scale. The future issues in a production scale are as follows: the piling method of raw material, ventilation condition and measures against offensive odor. 10 refs., 14 figs., 10 tabs.

    Explanation is made of the bioprocess which aims at treating the atmospheric CO2. As a result of investigation by the Electric Power Research Institute (EPRI), it was judged that the direct CO2 removal from the flue gas of power station is costwise disadvantageous and that the biological method by CO2 fixation is economical. The following are projects supported by the EPRI: The seaweed fossilization of CO2 is a medium depth sea mechanism of having seaweeds absorb carbon and making it remain residually in the deepsea even after the plants die. Study is being made of oceanic seaweed cultivation field development, non-calcareous seaweed cultivation and spore collection. The cost is advantageously low. The cultivation of seaweeds and halophilous plants utilizes their photosynthesis to collect CO2. There are examples of studying the possibility of cultivating those plants through comparison with the land trees. The growth ratio of halophilous plants is being also studied together with the possibility that the carbon remains as a residue. The whiting is a phenomenon in which biodecomposed subsea matter becomes CaCO3. Covered with CaCO3, the ssaweeds are deposited. Investigation is being made on the seaweed morphology and condition for the occurrence of whiting. 1 ref., 2 figs., 1 tab.

    This paper presents the results of performance tests of various kinds of adsorbents by static and dynamic adsorption methods to select the optimum deodorant (adsorbent) for ammonia gas (NH3). In the performance test of the static adsorption method, the amounts of NH3 adsorbed by 21 kinds of adsorbents including physical and chemical adsorbents were measure. The amounts adsorbed physical adsorbent No. 6, chemical adsorbents Nos. 18, 19 and 20 which showed higher adsorption ability were 0.0160g/g, 0.0284g/g, 0.0250g/g, and 0.0249g/g respectively at 30degC under equilibrium pressure of 50 mmHg. All of the adsorbent showed in Freundlich`s adsorption isotherm for NH3. Although the correlation between specific area, pore volume, mean pore radius, pH each adsorbent and the amount of adsorbed were tried, the correlation between the pH and the amount of NH3 adsorbed was significant. This suggests that the pH is a proper criterion for selection for adsorbents. The performance test of the dynamic adsorption method, was conducted for adsorbents Nos. 6, 18, 19 and 20 above-mentioned. The 10% breakthrough time was compared as the performance index. The breakthrough time of the adsorbent which the amount adsorbed was large was long but the breakthrough time was not proportional to the amount adsorbed. These results suggest that the performance test only by the static adsorption method is insufficient and that the breakthrough time test by the dynamic adsorption method is essential. 13 refs., 10 figs., 4 tabs.

    Outlined herein are a procedure developed to simulate performance of an energy-autonomous (independent) solar house referred to as HARBEMAN HOUSE (HH) built in 1996 in City of Sendai, comparison between the simulated and observed results, and characteristics of the solar house. The house is equipped with a solar collector and sky radiator, both installed on the roof, the former facing south to collect solar energy and generate hot water whereas the latter facing north to radiate heat and generate cool water. Both are connected to an underground heat-insulated tank having a capacity of 31m{sup 3}, which stores hot or cool water to keep their conditions for extended periods. The solar system operates in heat- or cool-storage mode. In the heat-storage mode, quantity of heat stored increases, although at a slow rate, as tank capacity increases. In the cool-storage mode, on the other hand, quantity of cool stored increases in proportion to tank capacity. This is because solar energy is collected throughout the year whereas cooling by radiation is concentrated in early spring. Loss rate of heat stored increases as tank capacity increases, and the opposite trend is observed with cool stored. 12 refs., 7 figs., 2 tabs.

    For the development of an airborne electromagnetic prospecting method capable of deeper exploration, a basic study was made about a system wherein a transmitter (source) is positioned on the ground and the receiving is done in the sky. Even in case of this airborne electromagnetic method, the TDEM method is supposedly advantageous over others as in case of groundborne exploration. In the study, the transient response of an airborne vertical magnetic field to a horizontal layered structure was calculated. The current source was 2000m long with a capacity of 30A. The one-layer structure was a 10 Ohm m semi-infinite ground, and the two-layer structure had a 100 Ohm m structure just under the one-layer structure. The result of the calculation suggests that, in the absence of a layer of extremely low resistivity, observation of an approximately 1 second long transient response aboard a helicopter flying at approximately 50km/h will enable an approximately 1000m deep exploration. Problems to affect airborne observation, such as swinging, natural magnetic field fluctuation, and artificially produced noises were investigated by use of a magnetometer suspended from a helicopter in flight. 2 refs., 6 figs.

    Heavy noises were measured and analyzed at a thermal spraying field, and soundproof characteristics of various noise insulating materials were studied experimentally. The frequency analysis of blasting and thermal spraying noises was conducted, and soundproof characteristics were analyzed of various noise insulating materials such as gas, liquid, viscous liquid, powder, granulated powder, coarse grain, and their composite materials. The result clarified that heavy noises of blasting and thermal spraying concentrate in high-frequency zone, generating heavy sound pressure levels. The sound transmission loss of gas showed a convex curve with a peak at 800Hz regardless of kinds of gases. He showed the maximum sound transmission loss or excellent noise insulating effect, being accompanied by CO2 and air. The noise insulating effect of liquid, viscous liquid, powder, granulated powder, and coarse grain materials was remarkable in the whole frequency zone, in particular, high-frequency zone. In addition, that of their composite materials was extremely excellent. 9 refs., 26 figs.

    The basic experiment on control of rigid bodies such as space robot and the unfolding behavior of space film structures was carried out under micro-gravity using the falling experiment facility of Underground Gravity-free Experiment Center Co. and its results were compared with simulation ones. On control of space robots under micro- gravity, since a robot body moves by reaction of a moving robot arm, the control experiment of arm movement was carried out with no use of any gas jet. The basic data on a large space system on a relatively low orbit were collected as motion of a multi-body rigid body in the nonlinear gravity field of the earth using a gradient gravity field simulated by magnetic field. Using the model of a solar cell film array as a typical example of unfolding space structures, the inverse folding phenomenon in storage of the space structure was studied experimentally under gravity-free condition. In addition, this paper summarizes some study results under micro-gravity such as motion of a flexible manipulator. 77 figs., 3 tabs.

    Just before the 21st century, Japan is demanded most importantly of reforming the industrial structures, breeding new industries, and working on global environment and energy problems. To solve these problems, emergence of material technologies based on original ideas is indispensable. However, Japan lacks a temperament to value original ideas and support them in positive manners. Structuring unique ideas and concepts with high originality is one of the most important intellectual production activities for human being. Understanding that these activities require incessant challenging spirit and accumulation of exhaustive efforts, a system should be structured to give the highest honor to researchers and groups who have made successes in this respect. It should be understood that development of the material technologies requires huge amount of fund, human resources and time, and national strategies should be established as required. Habitat segregation is to be moved forward in research and development, and a system will be built that links effectively the seed oriented research by universities and national research institutes with the need oriented research by business enterprises. The 21st century will be an age that many people can dream of their own success. (NEDO)

    Proportional, integral and derivative (PID) controls are used for a steering system and a main engine control unit installed in a vessel. Among them, this paper describes effectiveness of a PID gain tuning method using a limit cycle by means of relay control which is safer and simpler than conventional limit sensitivity methods. The present method was applied to an actual marine control system to conduct an actual vessel experiment. As a result of applying the method to a bow azimuth control system using a rudder, a new azimuth setting was set with an overshoot of 1.6 degrees in a ten-degree azimuth changing experiment. With respect to direction maintaining steering performance, the present method was capable of controlling the direction at a speed loss to about 80% of the ship`s autopilot. As a result of applying the method to a bow azimuth control system using a bow thruster, direction maintaining and changing control was realized in a low speed range in which rudder effect is lost. As a result of applying it to a main engine governor system and performing control of main engine rotation speed, it was found possible to derive control gains in a safe state without applying an excessive load to the main engine both under load and no load conditions. 14 refs., 8 figs., 11 tabs.

    In utilizing coal for high-efficiency direct power generation using fuel cells, it is necessary that coal be fed into the fuel cells after having been made into ash-free gaseous fuel. Research and development works are being carried out with an objective to develop a coal gasification furnace most suitable for fuel cells and establish a system to refine coal up to the one that can be fed into fuel cells. Fiscal 1995 has conducted investigations on coal gasification technologies, air separation technologies, and gas refining technologies as the important element technologies, and a trial design on integrated coal gasification fuel cell (IGFC) systems. This paper reports from among the above items the result of the trial design on an IGFC system using molten carbonate fuel cells. The paper describes system comparison on paths of produced gases and anode waste gas, comparison on refining processes using a wet system and a dry system, and parameter studies on oxygen concentration in gasifying agents. It was made clear that the suitable furnace is an oxygen blown coal gasification furnace, and the power generation efficiency at the system terminal can be higher than 53%. 11 figs., 6 tabs.

Collected in this report are the outline of the research and development of spintronic device technology, its current state and tasks and its importance from social and economic viewpoints, and the strategy that Japan should follow in the research and development of the technology. Important spintronic device technologies now attracting attention are mentioned below. The nonvolatile magnetic memory device MRAM (magnetic random access memory) is supposed to be the device which will enjoy practical application first among like devices. It is expected that the spin conduction device will lead to novel functions when the possibilities of the spin-dependent electric conduction phenomenon are further pursued. It is hoped that the spin optical device will be used as a light isolator, light spin logic device, field induced variable wavelength laser device, spin laser device, high-speed light switch, and so forth.

    This research project aims to establish a technique for crystal growth using pressure as a principal control parameter, and combining it with a microgravity condition, to develop a novel process material fabrication. Since the solubility of materials depends on pressure, it is possible to control a supersaturated condition for crystal growth by changing pressure. The growth condition can be controlled precisely, which is not possible by conventional methods that vary temperature and other factors. On the other hand, because a concentration diffusing field is formed autonomically around crystals in association with their growth, density convection is generated under gravity as a result of difference in the concentrations, making the growth conditions severely complex and uncontrollable. Ideal crystal growth condition control may be possible if the pressure control is performed under micro-gravity by which generation of the density convection can be suppressed. Realization has been achieved on in-situ observation by using high-magnification microscope which uses a diamond anvil cell, development of a hydraulic type optic pressure cell, and a high- speed crystal growing technology by means of pressure control utilizing the cell. New findings were also obtained on effects of pressure on crystal forms, and the pressure induced solid phase transfer mechanism. 67 refs., 49 figs., 3 tabs.

    This paper proposes a cone type electro-hydrodynamical (EHD) heat collector, describes its structure and principle, and mentions possibility of improving the heat collecting efficiency. The paper proposes a heat collector with a shape close to a cone. Trees are of cone form so that their every leaf, branch and truck can capture solar energy efficiently. Imitating this fact existing in the natural world, a cone-shaped heat collector was fabricated on a trial basis to discuss its heat collecting efficiency. Furthermore, black round stones are placed in the inner cone of the cone- shaped heat collector of double-glass structure. A low boiling point medium is placed between the inner and outer cones to cause corona discharge in vapor generated by absorbing the solar heat, and generate corona wind for an attempt to accelerate heat transfer into a heat exchanger. Thus, development was made on a cone-shaped high-efficiency heat collector utilizing electro-hydrodynamical (EHD) effect, and elucidation was given on dynamic phenomena of an electro-thermal fluid. Heat transfer in the EHD heat collector has a possibility of being accelerated by generation of ionic wind. In addition, it is thought that there would be an optimum value in applied voltage to increase electric charge supply as a result of corona discharge. 1 ref., 2 figs.

    The slow excitation response type power generator is studied when the rotor and stator of a 70,000kW-class model are combinedly subjected to an on-site verification test, when a good result is obtained. The rotor is disassembled for inspection, and its members are found to be sound without any problem in terms of mechanical strength. The quick excitation response type is studied when a 70,000kW model is experimentally built and subjected to an on-site verification test after a rotation and excitation test in the factory, when the pilot machine concept design is reviewed. In the study of a total system, efforts continue for the review of the model machine test method, improvement on generator design and analytical methods, development of operating methods, and the effect of its introduction into the power system. Since a He-refrigerated system is requested to exhibit high reliability for application to power equipment and to be capable of continuous long-period operation, a system having constituents with their reliability enhanced and an appropriate redundant system is developed, and a verification study is under way which will continue for more than 10,000 hours.

    It is intended to recover more effectively thermal energy currently discharged from marine vessels into air. This paper describes a diesel engine combined power generation system in which medium-order waste heat energy from a diesel engine for power generation in a marine vessel is recovered and utilized to operate a Rankine cycle system (using the waste gas as the high temperature source and sea water as the low temperature source), thus the thermal energy is recovered as a motive force. Two kinds of fluorocarbons and steam were discussed as a working fluid. Due to fluorocarbons making the whole system ultra-high in pressure, and from a viewpoint of high-temperature thermal stability, the temperature was remained at levels from 100 to 200 degC, and a single-stage expansion cycle was used. With the use of steam, a two-stage reheating cycle was employed, by which the temperature is raised fully up to 300 degC and effective head of fluid was taken largely. Ceramic paint was used as a means to prevent sulfur oxide corrosion when the system is used down to the dew point, and its effectiveness was verified. Motive force recovered by combining the steam two-stage reheating cycle and the ceramic painted heat collector was calculated, whereas electric power output of about 45 kW was obtained from a main generator with 450 PS. The derived thermal efficiency was about 26%. 2 refs., 24 figs., 2 tabs.

    Outlined herein are experimental results with a water hammer pump. It is a unique pump in that it depends only on potential energy of water to pump-up water. Water flows downwards from a reservoir at a high position into the pump , and is released from the exhaust valve. When velocity of water flowing in the pipe reaches a certain level, hydraulic force exceeds gravity of the exhaust valve to rapidly closes it, which is accompanied by rapid increase in pressure in the pump. High-pressure water flows into the air chamber, after pushing up the lifting valve, to compress air in the chamber. The lifting valve is closed, when pressure in the air chamber exceeds that in the pump, to pump up water in the chamber through the lifting pipe. Closure of the lifting valve produces a negative pressure within the pump, which, together with gravity of the exhaust valve, opens the valve again. The pump lifts water at 1.64l/min under the conditions of head: 3m and lift: 6m at an efficiency of 48.1%. 1 ref., 4 fig., 2 tab.

    Wind power now being used is mostly for power generation, and the power generating rotor is represented by the horizontal propeller type. The vertical type, such as Savonius rotor which uses drag force, may be used for special purposes. The Savonius rotor has been used for water pumping-up and ventilation for its characteristics of low rotational speed and high torque. The authors have proposed, based on the data collected by operating a wind mill of 10W, a method for reducing resistance by deflecting wind flowing onto the return bucket to augment drag force, in an attempt to make the system more functional. The Savonius rotor is equipped with a semi-cylindrical cover, and guide and side plates, to follow their effects. It is found that these plates work to augment power without needing expansion of sweeping area. 4 refs., 12 figs.

    The operation of a 1t/d PSU (process support unit) was studied for the NEDOL coal liquefaction process. In the modification of facilities, detailed designs were prepared for product oil reforming facilities and some equipment and devices were procured. In addition, the 3rd liquefaction reactor cone section and the neutron attenuation-aided measuring device were refurbished. In the injection of coal, a 62-day and 23-day slurry injection operations were accomplished using Tanito Harum coal, when the impact imposed on the yield of the product, etc., by the change of liquefaction catalysts and by gas phase hydrogen concentration enriching conditions was investigated, and the unit was examined for operationality. During a 42-day operation for maintenance, the unit was operated using only the slurry heater for the investigation of the initial reaction in liquefaction, and studies were conducted about the heater exit temperature, G/L (gas-liquid ratio), and the effect to ensue from the use of a different solvent. In the effort to develop and evaluate new materials, implantation tests were conducted for metallic materials and the 3rd liquefaction reactor was subjected to a non-destructive inspection. Wastewater from the process was examined for quality, and environment-related measurements were performed for the atmosphere. (NEDO)

    A highly heat-conducting AlN ceramic substrate is developed for the cooling of semiconductor integrated circuit devices and power controlling semiconductor devices. In the development of a low-temperature sinterable ceramic texture, a sintering assistant is selected. In this process various assistants are tested for the effect of their presence on the occurrence of AlN oxidation and on the magnitude of standard energy for aluminate compound formation. The volatility at high temperatures of the components of the assistants are also examined. The sintering assistant developed for this project (mixture of Y2O3, CaO, LaB6, and WO3) is used in the sintering of an AlN material powder developed by The Dow Chemical Co., and then it is demonstrated that highly heat-conducting AlN substrates are mass-produced by continuous sintering at 1600degC in a nitrogen atmosphere, the product having a relative density of 100%, average heat conductivity of 154W/mK, bend resisting strength of 440MPa, and a fracture toughness value of 3.8MPam{sup 1/2}. 6 refs., 92 figs., 10 tabs.

    The studies on combinations of high-performance compression heat pump and chemical heat accumulation systems are conducted to construct the optimum systems for air conditioning/hot water supply for large-sized buildings and local districts, and also for industrial processes. For partial optimization of super heat pump (SPH) accumulation system, the SPH operational mode is changed to find the optimum conditions. As a result, it is found that system efficiency is the highest, and hence the power cost is the lowest, when the system is continuously operated night and day, followed by 2-night/1-day mode and night alone mode, in this order, for office building air conditioning, district air conditioning, and hot water supply. The effects of combination of SHP and chemical heat accumulation systems incorporated in an industrial process for heating are estimated. The results indicate that power load leveling effect is not 100% but 92%, even when the heat required for the daytime operation is totally supplied from the chemical accumulation system. The skeleton of the super heat pump accumulation system simulator is finalized, and the elementary system modules are developed, to allow simulation of general flows. (NEDO)

    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.

    Rotating bending fatigue tests were carried out on austempered ductile cast iron (ADI) in order to investigate the statistical properties of life distributions of crack initiation and propagation, and also the evaluation of fatigue life. The results are summarized as follows: (1) The size of crack initiation sites of the material was represented by a Weibull distribution without regarding to the kinds of crack initiation sites such as microshrinkage and graphite grain. The crack initiation life scattered widely, but the scatter became much smaller as soon as the cracks grew. (2) The crack propagation life Nac which was defined as the minimum crack propagation rate showed lower scatter than the crack initation life. (3) The fatigue life of the material was evaluated well by Nac and the propagation rate after Nac. It was clear that the fatigue life of ductile cast iron was goverened by the scatter of Nac. 8 refs., 13 figs., 4 tabs.

    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.

    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)

    For the comprehensive and rational evaluation of technologies related to new energy and energy saving, investigations have been conducted about the history and trend of related policies and technological development. Japan saw a great change in the demand-supply structure in 10 to 15 years following the first oil crisis when oil was partially replaced with atomic energy and LNG and energy-saving efforts came into practice. However, the diversification of energy sources by developing new energies and improvement on the self-sustenance rate remain far from success. Related policies both in Japan and overseas are shifting from the conventional efforts for stable supply and economic growth to the handling of deregulation and environmental problems. Energy stratagem has been studied, not regarding energy technology as a mere economic task and working out how the demand for energy should be with the restricted resources, social economy, and environments, taken into account. Models and scenarios are proposed, for the quantitative analysis and evaluation of the energy stratagem wherein the development of technologies for new energy and energy saving are positioned clearly. Especially, concepts emphasized therein are the technique of power source planning and the development of regenerative energy. 24 refs., 32 figs., 15 tabs.

    For candidate materials of the ultra super critical (USC) turbine rotor in a coal fired power plant, the modified 12Cr steel and A286 steel are subjects of the study under the first step steam condition (316 atg, 593 centigrade) and under the second step steam condition (350 atg, 650 centigrade), respectively. The strength evaluation tests of the modified 12Cr steel untreated material and aging (630 centigrade, 4860 hours) material I were conducted previously, and obtained a prospect that the material can be applied to the first step turbine rotor. In this report, the strength evaluation tests and microstructure observation of the long period aging (630 centigrade, 8190 hours) material II, and the strength tests of the A286 steel have been conducted. As a result, it was found that the modified 12Cr steel is a stable material in the microstructure and has enough strength characteristics to apply the first step rotor, and the A286 steel also can be applied to the second step rotor. 9 refs., 27 figs., 8 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)

    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.

    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.

    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.

    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)

    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.

    This paper describes the following matters on shear reinforcing effects of carbon fiber nets on reinforced concrete beams: Test pieces of reinforced concrete beam having openings on its web reinforced with carbon fiber nets around the openings were subjected to shear fracture tests. The result verified that this reinforcement improves the ultimate withstand force of the beams and suppresses the decrease in beam rigidity and growth of cracks around the openings. Test pieces of reinforced concrete beam reinforced with carbon fiber nets around the web were subjected to shear fracture tests. The result verified that this reinforcement improves shear withstand force of the beams; the strain on the reinforced concrete decreases by nearly half when the amount of the carbon fiber net is doubled; the carbon fiber net is effective in suppressing diagonal cracks on the beams; and the shear withstand force burden on the carbon fiber net may be evaluated by the truss theoretical expression developed by the Civil Engineering Society and the experimental expression developed by the Japan Architectural Society. 5 refs., 10 figs., 7 tabs.

    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.

    This paper shows the results of the experiments on the thermal shock resistance and the thermal shock fracture toughness of ceramic blade used for high quality high temperature gas turbines. Using disk specimens of alpha SiC blade, the thermal shock resistance and the thermal shock fracture toughness are determined by means of Joule {prime} s heating at a central area of disk specimens at 1000 {degree} C (4.3 sec.) and at 1200 {degree} C, 1300 {degree} C, and 1600 {degree} C (4.5 sec.) . Both of the thermal shock resistance and fracture toughness decreases as the temperature increases until 1300 {degree} C, and then increases from 1300 to 1600 {degree} C. Both show maximum values at 1600 {degree} C. The writers consider that this is due to the stress release by the increase of ductility at high temperature. The experiments were also performed for SC-101 which is used for semiconductor base as reference material. The thermal shock resistance and fracture toughness of SC-101 at 1200 {degree} C is three times and 1.4 times larger respectively than SiC. The writers considered that it is caused by the high thermal conductivity three times larger than alpha SiC. 11 refs., 12 figs.

    This paper describes effects of allelochemicals secreted by Myriophyllum spicatum on growth of blue-green algae. In order to propose an effective growth inhibitory method of blue-green algae with less impact on the ecosystem, biological interaction (allelopathy) between large aquatic plants and algae was investigated. Pyrogallic acid, gallic acid, catechin and ellagic acid secreted by M. spicatum provided growth inhibitory effects of blue-green algae (Microcyctis aeruginosa), individually. Complex interaction and allelopathic contribution of these four polyphenols were evaluated. By comparing the actual effects with the expected values, synergetic growth inhibitory effects were recognized by adding four polyphenols at the same time. Furthermore, growth inhibitory effects were evaluated for actual culture solution of M. spicatum and simulated culture solution made by four polyphenols. As a result, it was found that these four polyphenols relate to allelopathy of M. spicatum. 25 refs., 6 figs., 4 tabs.

    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.

    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.

    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)

    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.

    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.

    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)

    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.

    Described herein are the results of the FY1994 research program for analysis and evaluation for thin film solar cells. The study on quantitative analysis of hydrogen atoms in a plasma determines quantity of hydrogen atoms in the plasma of monosilane diluted with hydrogen. It is found, contrary to expectation, that quantity of hydrogen atoms in the plasma decreases as it is more diluted with hydrogen. The study on light-induced degradation of the thin chlorine-base amorphous silicon films confirms that the plasma CVD method with 20% of dichlorosilane gas added to monosilane gas produces the thin amorphous silicon film 3 times faster than the conventional method. The thin film has essentially the same defect density as the one prepared by the conventional method, showing good photoelectric characteristics. The thin film of chlorinated amorphous silicon has a 1 digit lower defect density than the conventional one of amorphous silicon, as revealed by the accelerated degradation test with irradiated laser light and the constant current method to determine saturated defect density. 3 figs.

In the modification of facilities, oil product reforming facilities basic designs were prepared enabling the hydrogenation of coal oil after the liquefaction reaction process for reducing hetero compounds in coal oil in the NEDOL process. In the study of operation, pre-operation verification was accomplished under facilities cost performance exploring conditions for the pilot plant and, for the purpose of exploring optimum conditions for the NEDOL process, a 62-day and 25-day slurry injection operations were conducted using Tanito Harum coal and natural pyrite. In a 16-day operation for maintenance, data including mass balance were collected for the investigation of the initial reaction in liquefaction. The specimen sampling section of the high-temperature/high-pressure sampling device, which had been moved to the 3rd liquefaction reactor, was tentatively operated. In the solvent hydrogenation process, 2 hydrogenation reactors were connected in series and then operated for the verification of operationality. (NEDO)

    The dynamic mechanical properties of the composites of poly (p-phenylene terephthalamide) (PPTA) fibers (rigid molecules) and poly (methyl methacrylate) (PMMA) matrix (flexible molecules), were investigated as a function of the surface area of the fiber and temperature. These composites showed reinforcing effect indicated by the storage modulus (E') over the whole temperature range. At the temperature region of glassy state, E' was influenced by both the elastic modulus and the surface area of reinforcing fiber. However, at the temperature region of rubbery state, E' depended mainly on the surface area. Disappearance of {beta}-relaxation, that is attributed to rotation mode of the side-chain, and the shift of the higher temperature side of {alpha}-relaxation of main-chain of PMMA were observed in the PPTA composite with larger surface area. These results are attributed to an interaction at the PPTA/PMMA interface. Furthermore retardation of thermal decomposition of PMMA was observed in the presence of PPTA. It can be shown that the higher activation energy for the thermal decomposition of PMMA is equivalent to higher interaction energy in the PPTA composites. The shift of -NH, >C=O IR absorption band of benzanilide, a model compound of PPTA, with change in the PMMA composition proved that the interaction is chemically originated from the formation of hydrogen bond between PPTA and PMMA.

    Survey was made on residential waste treatment in Shanghai city. Shanghai city with nearly 13 million registered residents produces on average 10,000-11,000 tons/day residential solid wastes. Such wastes are basically disposed by land filling. A landfill site has a current disposal capacity of 7,500 tons/day, and is scheduled to be expanded up to 9,000 tons/day. Problems of waste disposal in Shanghai city are as follows: transportation of wastes collected in the city by trucks, transportation through transit stations to the landfill site by ships, and high disposal cost. Shanghai Environmental Sanitation Bureau is pursuing researches on recycling of wastes, reduction of wastes and harmless treatment in place of conventional land filling. As the survey result, adoption of complete separate collection of wastes is basically important, and application of the latest technologies such as combustion treatment for every waste, heat use, gasification fusion furnace, and RDF (refuse derived fuel) for coal-firing boilers should be considered. 86 figs., 18 tabs.

    This paper summarizes the result of a survey for promotion of geothermal development and an overall analysis of the Akinomiya area in fiscal 1996. The subject area is located in Katsuo Town in south of Akita Prefecture. The geothermal reservoirs are regulated by the irregular construction created by upheaval and subsidence of the pre-Tertiary basement rocks. The underground temperature construction shows the temperatures rising toward Mt. Yamabushi. The latest geothermal activities should have taken place after the eruption of Mt. Takamatsu. The geothermal activities near the Arayu area have been most active until recently, and is still predominant. Transformation activities were active in the former period of the Pleistocene era. The acidic transformation band has been active after sedimentation of andesites in Mt. Takamatsu thereafter, which should have been active not only in areas where it is now active on the ground surface, but also in greatly wider areas. Geothermal fluid flows being regulated by faults, whereas fractures with high permeability existing along the faults are suitable for developing steam collection. Hot spring waters were produced by the geothermal fluid having risen along the faults and been mixed with and diluted by ground surface water near the ground surface. Areas promising for geothermal development would spread over the areas with high permeability along structural lines such as faults which show the convection type temperature pattern and temperatures higher than 250 degrees C.

    Researches were conducted for the goal of proposing a totally new process enhanced in efficiency and energy saving, and capable of CO2 separation. In fiscal 1997, hydrocarbon materials were reformed by oxygen separated within a system allowing fuel cells to generate power efficiently, when all the emitted CO2 was separated and recovered within the system. Furthermore, cold heat was utilized for the acquisition of liquefied CO2 gas products. A part of oxygen separated at the fuel cell cathode was recycled into the combustion section external to the tubular reaction reformer, and CO2 was separated by mere cooling from the combustion products for the simultaneous production of by-products such as high-purity nitrogen gas and liquefied CO2 for a great improvement in economy. In fiscal 1998, the system was improved. Proposed then was a new system in which an oxygen partial oxidation type reformer assumed the nuclear role, separating all the oxygen at the cathode, reusing part thereof for oxygen enrichment, and feeding the rest thereof into the reformer. The design realized the recycling of the whole of the products of the two cell electrodes into the reformer for the maximum reuse of the products of the hydrogen/oxygen separation function. (NEDO)

    The study is conducted for the underground thermal energy storage system which utilizes heat capacity of the underground, e.g., aquifer, to exchange heat with the underground, and the FY 1999 results are described. For establishment of the concept of the underground heat storage systems, 2 sites are selected for each of Tokyo, Osaka and Sapporo for the study as the geological ground models, for their weather characteristics. Two cases are considered for the site where underground heat exchangers are installed, open space and immediately below a building. The heat-storage system comprises a high-efficiency heat pump, water heat-storage tank and cooling tower. The evaluation results indicate that energy saving rate of 37% or more and CO2 reduction rate of 9.5% or more are achievable in all areas except Sapporo, i.e., Tokyo and Osaka. The economic evaluation results indicate that the simple pay-out period is around 100 years for Tokyo and Osaka, and 80 years for Sapporo. The underground heat storage system is approximately 10% lower in life-cycle cost than the conventional system, 3 versus 3.3 billion yen for the period of 60 years. (NEDO)

    Features of a straight wing type vertical axis wind turbine (VAW) and its airfoil sections were studied. The wind turbine in which various aerodynamic work components are mounted on the rotation axis normal to the ground surface is named VAW. Like the airfoil section of aircraft, in lift type VAW, wind turbines were driven by lift 70-90 times as large as drag in some cases. Features of the VAW airfoil section which is a straight wing in plan and a fixed pitch wing (with a fixed angle to a blade support arm) in cross section, and those of wind turbines were studied. Some factors affecting the features, work principle and performance of VAW were clarified. On airfoil sections, products of each weight function and each corresponding aerodynamic factor (lift, drag and pitching moment factors) were plotted on an attack angle ({alpha}) axis. From the conditions for increasing the total sum of areas drawn by the products on the {alpha} axis, various characteristics required for airfoil sections were clarified. Such characteristics nearly agreed between an airfoil section for favorable starting characteristics and that for high efficiency. 3 refs., 7 figs.

    The effect of surface tension on free surface flow around floating models is discussed experimentally and numerically. Three-dimensional free surface flow around vertical circular cylinders floating in a circulating water channel was visually observed, where a surface-active agent was added to water. The results are analyzed using Weber number. The numerical analysis was done for vertical cylinder and CY100 models using the Rankine source method. Weber number of at least around 120 is necessary to eliminate the effect of surface tension from free surface flow around the CY100 model. The numerical analysis for the cylinder model needs simulation with wavelength shorter than that of free surface wave used by the Rankine source method. The model for the resistance test should be at least around 7m long to eliminate the effect of surface tension at Froude number of 0.1 or higher. 15 refs., 12 figs., 2 tabs.

    A method to predict drift force acting on a floating structure has been developed for a marine structure consisting of a number of floating elements, positioned in a region having a slope at the sea bottom. When a huge marine structure, such as floating air port, is located in a coastal area, scale of the overall structure is very large, of the order of scale of water depth change. The new method assumes that a marine structure consisting of an infinite number of cylindrical floating elements is installed in parallel to the seashore, where symmetrical nature of the configuration allows to predict behavior of the whole system by analyzing one element. Integration of pressures acting on structure surfaces determines the horizontal component of the drift force acting on the structure. Being influenced by topography, drift force predicted peaks at a frequency different from that for the level predicted on the assumption of constant water depth. This indicates the necessity for consideration of seabottom slope and effects of broken waves at the seashore. 6 refs., 12 figs.

    A permanent borehole energy storage system utilizing solar energy and waste heat from coolers is simulated, to be used as an air conditioning system for super-tall buildings. A 100m-long pipe is buried vertically into the ground, and a heat medium is caused to circulate in the pipe for the exchange of heat with the soil. Thirty borehole units are used, each measuring 9m{times}9m (with the pipe pitch being 3m). Solar cells occupying half of the wall surface facing south and solar collectors installed on the roof supply electric power and heat for cooling and warming. Heat in the ground is transferred mainly by conduction but also is carried by water and gas in movement. So, an analysis is carried out using an equation in which heat and water move at the same time. Because waste heat from cooling and warming systems is accumulated in the ground and none is discharged into the air, big cities will be protected from warming (from developing heat islands). As compared with the conventional boiler-aided air conditioning system, a hybrid borehole system incorporating solar collectors and solar cells will bring about an 80% reduction in CO2 emission and annual energy consumption. 7 refs., 3 figs., 4 tabs.

    Studies have been made about a heat accumulation tank type cooling system making use of radiation cooling that is a kind of natural energy. The daily operating cycle of the cooling system is described below. A heat pump air conditioner performs cooling during the daytime and the exhaust heat is stored in a latent heat accumulation tank; the heat is then used for the bath and tapwater in the evening; at night radiation cooling is utilized to remove the heat remnant in the tank for the solidification of the phase change material (PCM); the solidified PCM serves as the cold heat source for the heat pump air conditioner to perform cooling. The new system decelerates urban area warming because it emits the cooler-generated waste heat not into the atmosphere but into space taking advantage of radiation cooling. Again, the cooler-generated waste heat may be utilized for energy saving and power levelling. For the examination of nighttime radiation cooling characteristics, CaCl2-5H2O and Na2HPO4-12H2O were tested as the PCM. Water was used as the heating medium. In the case of a PCM high in latent heat capacity, some work has to be done for insuring sufficient heat exchange for it by, for instance, rendering the flow rate low. The coefficient of performance of the system discussed here is three times higher than that of the air-cooled type heat pump system. 8 refs., 5 figs., 4 tabs.

    In an effort to extend cooperation for reducing pollution in urban areas in the Asia-Pacific Region, a laser radar system was constructed in the city of Djakarta, Indonesia, in 1996, and a follow-up started in fiscal 1997. The aim is to collect information necessary for atmospheric environment improvement through observing pollutant distribution and movement in the upper atmospheric layers over the city. Mie-scattering lidar (laser infrared radar) observation has uninterruptedly been on since the summer of 1997, the system collecting data about Djakarta's atmospheric boundary structure throughout the year. The data indicate great changes in the atmospheric boundary structure between the dry and rainy seasons. The result of intensified observation conducted in the dry season shows that the altitude that the mixed layer reaches in the inland region is higher in the daytime and lower in the nighttime. It is necessary to compare the result with atmospheric pollution data collected on the ground surface and determine the relationship between the behavior of pollutants and the circulation of land-and-sea breeze. The data of September, 1997, reveal an aerosol layer at altitudes of 2km and higher, and this is attributed to forest fires. The result of intensified observation conducted in the dry season of 1998 is also stated. (NEDO)

(1) In an facultative anaerobe, K. oxytoca, the repressor gene, nifL was destroyed, and the activator gene, nifA was fortified, to attain a novel mutant strain R16, which fixes nitrogen even in the presence of NH{sub 4}{sup +}. (2) In a microaerophilic nitrogen fixer, A. lipoferum, the regulatory genes draT and draG were cloned and analysed, and an improved strain TA1 was obtained by introduction of K. oxytoca nifA gene. (3) In an aerobic nitrogen-fixer S. paucimobilis, the nifA gene was cloned and sequenced, and the activity was expressed in E. coil to show that the product activates the nif promoters of Azospirillurn and Klebsiella. (4) The improved strains K. oxytoca R16 and A. lipoferun TA1 were inoculated to rice plant cultured in a pot without addition of nitrogen source. The inoculated plant showed twice as much dry weight as the noninoculated plant, showing that the improved strains are effective to stimulate the growth of rice. (NEDO)

    The aim is to develop a method of processing oxygen concentration distribution in human organs into an image by computed tomography using near infrared rays capable of transmitting through living tissues. Since the photoabsorption spectra of hemoglobin etc. in blood vary according to the degree of their oxidation, an oxygen concentration level is determined by measuring the magnitude of the variation. In the imaging method named in the title, the object is irradiated with picosecond-level near infrared pulses from all directions successively, the pulses after transmission through the object are measured at all directions at a picosecond-level time resolution, and the distribution of pulse scattering and absorption characteristics are subjected to algorithmic calculation, the outcome is converted into oxygen concentration levels, and an image is obtained. A 64-channel time resolution measurement system is constructed, and is applied to living tissue models (phantoms) and animals, and an image is obtained and evaluated. On the basis of the result, a patient is examined for clinical evaluation, and an image reflecting the distribution of variations in hemoglobin oxygen concentration is obtained for the head of the adult patient. A spatial resolution of 1cm is achieved in case of a phantom 10cm in diameter. In the case of 64 channels, measurement takes approximately 20 minutes and mapping image data measurement takes approximately 7 minutes. (NEDO)

    For the coal liquefaction, improvement of liquefaction conditions and increase of liquefied oil yield are expected by suppressing the recombination through rapid stabilization of pyrolytic radicals which are formed at the initial stage of liquefaction. Two-stage liquefaction combining prethermal treatment and liquefaction was performed under various conditions, to investigate the effects of reaction conditions on the yields and properties of products as well as to increase liquefied oil yield. Consequently, it was found that the catalyst contributes greatly to the hydrogen transfer to coal at the prethermal treatment. High yield of n-hexane soluble fraction with products having low condensation degree could be obtained by combining the prethermal treatment in the presence of hydrogen and catalyst with the concentration of slurry after the treatment. This was considered to be caused by the synergetic effect between the improvement of liquefaction by suppressing polymerization/condensation at the initial stage of reaction through the prethermal treatment and the effective hydrogen transfer accompanied with the improvement of contact efficiency of coal/catalyst by the concentration of slurry at the stage of liquefaction. 4 refs., 8 figs.

For the solvolysis, the conditions under which plastics are hydrolyzed in supercritical water are investigated, and the basic data are obtained for the optimum conditions under which thermoplastic resins are hydrolyzed. The mechanisms involved in hydrolysis of polymers in supercritical water are elucidated to some extent. The environment-friendly process for synthesizing polycarbonate in supercritical carbon dioxide gas is investigated, and the continuous flow sheets are established for securing almost 100% conversion in the presence of an inexpensive catalyst. For the oxidation, the tests are conducted to burn low-grade coal in supercritical water, and the conditions under which it is burnt without releasing acid and toxic gases are found. For the hydrogenation, heavy fuel oil is treated in supercritical water to produce the lighter products. The conditions under which light oils and gases are produced are clarified, and the basic data are obtained for producing light gases from the resultant coke as the by-product. (NEDO)

    A floating structure such as an international airport is anticipated to have a length of about 5,000 m and a width of about 1,000 m. A singular point method may be used as a method to estimate force that such a floating body is subjected to from waves. In order to derive a solution with practically sufficient accuracy, 1250 elements are required in the length direction and 250 elements in the width direction, or a total of 312,500 elements. Calculating this number of elements should use finally a linear equation system handling complex coefficients comprising 312,500 elements, which would require a huge amount of calculation time. This paper proposes a method to derive solution on wave forces acting on a super-large floating structure or fluid force coefficients such as added mass coefficients and decay coefficients at a practically workable calculation amount and still without degrading the accuracy. The structure was assumed to be a box-shaped structure. Strengths of the singular points to be distributed on each element were assumed to be almost constant except for edges in lateral, oblique and longitudinal waves. Under this assumption, the interior of the floating structure excepting its edges was represented by several large elements to have reduced the number of elements. A calculation method proposed based on this conception was verified of its effectiveness. 2 refs., 25 figs., 3 tabs.

    In order to compare public knowledge and behavior on recycling of household wastes in cities in Japan and the United States, a questionnaire survey was carried out in the city of Seattle, Washington. In recycling the household wastes in Seattle, the government or private commissioned contractors collect usually the recyclable wastes in the form sorted out from ordinary wastes. The classified wastes collection has been performed as a citizen`s activity in the city of Seattle. While the wastes collection is carried out mostly by using tax money in Japan, the city of Seattle uses ordinary wastes collection on a paid basis and free-of-charge classified collection in order to encourage citizens to participate in the activity. However, about half of the population has an opinion that all the wastes collection service should be made free of charge. If it is made completely free, the municipality will have to convince the citizens on increase in the local tax. As the local governments in Japan who stand largely behind the times are inaugurating the recycling operations, the difference in the people`s consciousness between Japan and the United States, and the differences in the consciousness of responsibility assumption among administrations, corporations, and citizens, and in the consumption life patterns include a number of suggestions. 3 refs., 1 tab.

    Ferritin, the iron storage nonhaem-protein contains a ball of hydrated iron oxides (Fe2O3{center_dot}nH2O) in its core, which is paramagnetic at room temperature. It is reported the hydrated iron oxide is the precursor of magnetite (Fe3O4) in the magnetotactic bacteria and polyplacophoran mollusks. It is not known whether this is the case for other organisms. In our study, we report the first detection of magnetic material in the human brain through the use of SQUID magnetometry. The material was characterized by HRTEM and EPMA. It was affirmed the material was a single crystals of magnetite. Magnetite distribution in tissues might be related with ferritin, if the core of these molecules are involved in magnetite formation in human. In general, both Perls staining and MRI maging methods are adopted routinely for determining the relative amounts of Fe(+III) in the whole brain, which is dominated by ferritin. Both methods suggested high levels of Fe(+III) distribution in the globus pallidum, putamen, caudate, internal cerebral capsule of the cerebrum, red nucleus of the mid brain and lower concentrations in the substantial nigra of the mid brain and the dentate nucleus of the cerebellum. Whereas, our experiments showed that the distribution of magnetite is rather even in the whole human brain averaging 4 ng per gram of tissue (except for the meninges, where it is 20 times higher). 20 refs., 8 figs., 1 tab.

    The geographical position or environment is set on the assumption that the natural energy of a detached house is used in a hybrid state. Moreover, the energy consumption of the house and the natural energy supply obtained from the geographical position were compared and investigated. As a result, the energy consumption is 10,617 kWh, and the energy supply is 8,236 kWh. About 78% of the whole consumption can be theoretically made from natural energy. The energy supply is calculated on the low side during prediction. Therefore, an increase in the energy supply is expected by installing a solar collector based on solar energy, expanding the solar panel area, and increasing the number of wind mills. However, this energy is partially lost via an inverter while it is supplied to the general domestic equipment. At the six main points in Tokyo and its districts, the adaptability of natural energy used based on the regional characteristics is investigated presently and the installation of a system is examined. 13 refs., 2 figs., 6 tabs.

    The paper investigated/studied `space light modulation materials,` `dynamic hologram/memory materials,` `optical waveguide path materials,` etc. which become key materials in the high speed two dimensional processing. As to electrooptical materials proposed in this investigational study, the external electric field and the electric charges generated make quality of molecules themselves directly change to memory strong/weak signals of light. Therefore, the response velocity becomes less than a millionth of that of the liquid crystal display, and high speed which is needed for realtime moving image processing is anticipated. Hologram includes the phase information in addition to information on light strength. Therefore, it is a large capacity record medium and at the same time a record medium which can read/write two dimensional information as it is. With optical fiber, images cannot be transmitted as they are. Light waveguide path materials are those that accumulate roles of mirror and lens in a sheet of the material and construct a system which is strong in vibration, as optical parts connecting among materials for two dimensional data processing. 273 refs., 107 figs., 17 tabs.

    By the ICB method which is one of the ion engineering methods, photomultipliers were formed using organic dye thin films. By changing the energy to bond traps on thin film/metal electrode interface and electric charges by change of acceleration energy of ion beams, a technology was developed for adjusting the optimum operating temperature between -20 degrees C and +100 degrees C. The wide range of operating temperature and favorable SN ratio can be realized. It was made clear that the dark current of the photomultiplier is composed of two components of contribution by the residual charge stored on the interface at photomultiplying and of contribution by charge injection from the Schottky barrier. Based on this, the residual electric charge removal method by heating and applied pulse voltage was developed. The development for practical use was studied of ultra-high sensitive photoelectric converters. As an intelligent photo sensor, a biomimetic visual photosensor was proposed which uses amplification/memory/arithmetic functions and film formation/processability of organic thin films. The paper also described the image sensor. (NEDO)

On the effect on osteoblast shape and gene expression, although fluorochrome reacting with Ca was well taken into cells, no significant difference in Ca content in cells was observed before/after falling. Expression of genes related to cell propagation was controlled under micro-gravity. Protoplast fusion of Lentinus was unaffected by micro-gravity. The mRNA fragments of gravity sensitive mutant of rice plant were affected by micro-gravity. Paramecium was set swimming in solutions with different specific gravities. The reaction behavior of Paramecium was affected by the difference in specific gravity between cell bodies and solutions. The water content metabolism functions of a mouse with needle stimulus, in particular excretory, were slightly promoted by micro- gravity.

    The secondary dental caries easily occur by breeding of bacteria in cavities between living body and composite resin, false tooth or root of tailored tooth as tooth repairing materials. The antibacteria activity of tailored dental materials was thus studied by implanting Ag ion. The antibacteria effect with time after culture of caries bacteria was studied by implanting Ag ion into SiO2 powder, PMMA samples and Ti alloy samples at 20 and 200keV in energy of ion. In addition, the antibacteria activity of SiO2 powder as composite material was found at 25keV which was previously effective for the antibacteria activity. This SiO2 filler (Ag{sup +} filler) showed the antibacteria activity on every bacteria sample after 2h, and in particular, could kill all of 3 kinds of bacteria obtained from a composite resin surface after 12h. The number of living S. salivarius was reduced by half after 12h. The application of the composite resin filler implanted with Ag{sup +} is significant to prevent recurrence of caries. 5 refs., 27 figs., 7 tabs.

    The research and development have been conducted to apply neural networks to interpretation technique for 3-D MT data. In this study, a data base of various data was made from the numerical modeling of 3-D fault model, and the data base management system was constructed. In addition, an unsupervised neural network for treating noise and a supervised neural network for estimating fault parameters such as dip, strike and specific resistance were made, and a basic neural network system was constructed. As a result of the application to the various data, basically sufficient performance for estimating the fault parameters was confirmed. Thus, the optimum MT data for this system were selected. In future, it is necessary to investigate the optimum model and the number of models for learning these neural networks. 3 refs., 5 figs., 2 tabs.

    It was intended to serve for establishing specifications for a next generation SAR such as PALSAR through studying methods for evaluating and utilizing the multi-frequency, multi-polarized wave SAR data. Placing an emphasis on utilization of the NASA`s AIRSAR, identification was made on backscatter amount recorded on the SAR data, terrestrial constitutional substances, patterns of the ground surface, micro-topography and such terrestrial conditions as vegetation and land utilization. Their mutual relationships were also analyzed. A noise reduction method usable on multi-band data can be applied to the AIRSAR data, and can reduce noise effectively. Images with more volume of information can be acquired from multi-band images with the same polarization wave than from multi-polarization wave images with the same band. As a result of estimating terrestrial permitivity by using the method invented by Dubois and van Zyl, most of the subject area is judged to have terrestrial substances dried at the time of having acquired the images. A colluvium rich with exposed rock regions and gravels was identified as an area having higher permitivity than the former area. Images of terrestrial roughness were divided largely into smooth flat lands, sand and gravel distributed regions, exposed rock regions, and plant distributed regions along river basins. 3 refs., 2 figs., 1 tab.

    With an objective to detect gas leaking from an underground gas pipeline, discussions have been given on a method which utilizes acoustic characteristics of leakage. On leaking sound generated from damaged portions, the form of damaging was hypothesized as pinholes, and spectra of leaking sounds from holes with different diameters were measured. The dominant frequency decreases as the hole diameter increases, while it is in a region of relatively high frequency of 1 kHz or higher. However, detection from the ground surface was impossible when cover soil has thickness from 0.5 to 1.5 m. In an experiment to measure leaking sound inside the pipe, pressure in the pipe was adjusted to 0.02 atm which is a standard pressure for a low-pressure pipe, and the sound was measured when the hole diameters were varied. In any of the results obtained by varying the hole diameter, spectra having the dominant frequency in the region of 1 kHz or higher were measured. In addition, it was found that sound pressure difference of as much as 50 dB at maximum is generated as compared with a case of no sound leakage. The above results verified that monitoring the high frequency of 1 kHz or higher is effective in detecting leakage from small damages. 2 refs., 4 figs.

    From a viewpoint that cancer, cerebral hemorrhage, heart disease, etc. caused by the progress in aging are problems not only to Japan but to all developed countries, a possibility of Japan`s joint study with other countries was examined to promote efficiently and effectively research/development of the apparatus required. Moreover, from a viewpoint of being the same Asian countries, a possibility of the joint study was examined also with developing countries which are largely different in disease structure and environment of the use of apparatus from developed countries. In the examination on medical/welfare apparatus technology of China, before the site examination, a book of data was arranged on the actual state of population and disease structure and the R and D situation of medical/welfare apparatus in Japan, and at the same time, celebrated persons in China were introduced by the scientific society side as widely as possible. By this preliminary study, the original objective of the examination could be achieved. In the examination with the U.S. and Europe, Japan held meetings with engineers of the U.K., France and the U.S. Japan`s `load control type walking supporting apparatus,` of which the development was finished, was very highly evaluated by each organ of the countries

    The paper made an analysis of the heat island phenomenon in the Kanto area using 3-D numerical analysis models and a study on the effectiveness of the measures to prevent it. The models are composed of advection/diffusion models of heat/steam in the wind-velocity field and atmospheric air, heat diffusion models in the underground and undersea, and heat balance models on the ground surface and sea surface. In the calculation, a simulation was conducted of the case of taking the following three measures: the case where the exhaust heat was reduced 30% in the assumed typical day of summer; the case where the heat volume of buildings/trunk roads was reduced; the case where the evaporation efficiency of buildings/trunk roads was raised. The result of the study was as follows: The reduction effect of the exhaust heat is totally large, but precisely observing, some meshes contrarily showed rises in temperature in the suburbs. Also in the case of reducing the heat volume, the same phenomenon occurred, but the effect was large in the center of a city. It was found that the effect was unexpectedly large in the case of increasing the evaporation efficiency. 7 refs., 14 figs., 2 tabs.

    Studies were made for the purpose of probing effects of utilizing body sensory game machines for the functional recovery training and exercise of the elderly and handicapped, with the fiscal 2000 results reported. In the verification by existing game machines, a game center was made available free of charge, providing free experience for the elderly, with the image traced of the elderly for the game machines based on the record of the machines used, questionnaires and interviews. In addition, four body-sensory game machines that were supposed to be effective for the exercise of the joints were installed in a day care center for six months, with a verification test performed on the adaptability of the elderly to the speed and the like of the game machines. In the development of a game machine intended for the exercise of the lower extremities, researchers tackled the development of a game machine in which an entertainment/amusement nature was added to the exercise of the lower extremities. An experimental model was developed based on a principle providing a virtual reality as if the user were walking in a tourist area of scenic beauty by moving a scenery linked with a foot pedal type exercising pattern.

    For the purpose of establishing the basement technology relating to photoreactive materials which make remarkably higher density and larger capacity of the information recording possible, the following were made for photochromic materials and PHB materials: elucidation of the photoreaction mechanism, development of materials, development of material processing/structure technology and development of evaluation technology. The target is to establish the technology of the multiplex recording which is applicable to the super-high density recording in relation to PHB materials/organic photochromic materials which have potentiality of photon-mode recording. PHB materials were developed which have potentiality of 600 wavelength multiple recording and 5 electric field multiple recording in 4.2K and 9 wavelength multiple recording in 77K. Photochromic materials were developed which have high sensitivity and preservation stability and have potentiality of 10 wavelength multiple recording at room temperature. A new photo-recording method was found out by which the orientation of liquid crystal is photo-controlled and potentiality of the multiple polarization was shown. Moreover, the fabrication was successfully made of PHB materials and photochromic materials which make non-destructive readout operation of more than 10{sup 4} times possible. (NEDO)
