    As for their outputs, the 3kW separately-excited and self-excited photovoltaic power plants yield daily averages of 7.8kWh and 6.9kWh, respectively, and this means that the self-excited type is inferior to the separately-excited type in terms of conversion efficiency. Automatic measuring devices for photovoltaic characteristics are installed at Sapporo, Sendai, Nagoya, and Miyazaki, which will elucidate regional difference in photovoltaic characteristics. A simulation of photovoltaic characteristics is performed and the resultant value is compared with the yield of an experimental 3kW system, and the result of the comparison is found reasonable. Cell arrays are subjected to investigation for configurations lowest in output loss for the respective shadow patterns. Harmonic characteristics are analyzed under plural-interconnection circumstances. Studies are made to miniaturize and simplify system constituents, and it is found that a 3-hour storage is proper for a 3kW-class storage battery. It is also found that a self-excited type suffers less voltage fluctuation in interconnected operation on a small short-circuit capacity system. Possibilities are that independent operation is started when output is larger than load, which is to be detected by checking changes in phase, frequency, etc. Array configuration, arresters, and shielding wires are taken up for the study of measures to cope with direct thunder strokes.

    This paper reports the study results on the standard weather data necessary for simulation of PV power generation systems in fiscal 1994. In the study on the selection criterion of the standard weather data from the viewpoint of PV power generation systems, three typical years are used; a year with average solar radiation, and two years with extremely less and more solar radiation for safe simulation. The standard weather data are arranged for output calculation of PV power generation systems by selecting the most typical year based on long-term observation data. The data to be arranged are as follows; total, direct and scattered solar radiations incident upon a horizontal surface, solar radiation upon a slope surface, sunshine duration, air temperature, wind direction, wind velocity, amount of precipitation, and snow depth. For arrangement of the nationwide standard weather data, estimation of total solar radiation is necessary based on sunshine duration data observed by all weather bureaus. In this study, the estimation model was developed of the total solar radiation integrated with time from rotary pyrheliometer data. 5 figs.

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

    For collecting solar radiation data necessary for the prediction of power to be outputted by photovoltaic power systems in Japan, detailed experiments and observations were conducted with an emphasis placed on the amount of solar radiation on a slope facing north and on the amount of solar radiation broken down by wavelength. Models were analyzed, and the fiscal 1999 results were compiled. In the validation of a model of solar radiation on an inclined surface, a review was conducted using the 1-year data observed at the Takasaki station for all directions, including solar radiation on the slope facing north, and the validity of the model was confirmed. As for the validation of a model for estimating solar radiation by duration of sunshine, it was examined for accuracy using the same data, and was found to be fairly high in accuracy. For the maintenance of solar radiation data for each wavelength, continuous observation was conducted for each wavelength of solar radiation at the Takasaki station using a multi-filter spectroradiometer, and a technique was established to determine spectral distribution using the observed data. Moreover, continuous observation of global diffused solar radiance was conducted using a sky scanner at the said station and solar cell power generation characteristics was continuously monitored.

    Attention is paid to behavior at the molecular level with reference taken to the photosynthetic mechanism, and a behavioral mechanism is proposed, which incorporates, in place of the conventional band model, a concept of a molecular structure based on electron transfer, excitation energy transfer, and reactions of oxidation and reduction. Discussion is then made on elements of technology development for the embodiment of high-efficiency organic ferroelectric thin-film solar cells. The elements taken up include the feasibility of organic ferroelectric thin-film cells, photoelctric conversion systems of plants and photosynthetic bacteria, solar cells using donor-acceptor type dyes, organic thin-film solar cells using conductive polymers, and efficient photoexcitation of organic dyes. Fullerene compounds are semiconductive and their band gaps may be controlled to stay within the range of 0.75-1.9eV, and this justifies a hope that they will serve as solar cells. As for TPV (thermophotovoltaic) conversion, it is under development mainly at NASA (National Aeronautics and Space Administration) as a transportable power source based on heat of combustion. Efforts are also being exerted since 1990 in five European countries to develop TPV systems for small-scale cogeneration. (NEDO)

    The present state and trend are surveyed of organic ferroelectric thin films, new carbon materials, fullerene compounds, and thermophotovoltaic (TPV) power. In the study of organic ferroelectric thin-film solar cells, the effort still remains at the basic stage, with the conversion rate as low as 3% in Europe and 2% in Japan. The progress of basic studies, however, is worth attention. It is deemed that 15% is the photoconversion rate to be currently expected from new carbon material solar cells. Fullerene compounds include some semiconductors whose bandgap values may be controlled across a 0.75-1.95eV range, and they may find their place in thin-film solar cells. However, their physical properties are not fully known, and their development into devices such as solar cells is scarcely reported. The research and development of TPV in the U.S. is led by NASA (National Aeronautics and Space Administration) and NREL (National Renewable Energy Laboratory), with their efforts concentrated on the development of portable power sources utilizing combustion heat. In Europe, TPV application to small-scale residential cogeneration systems is under study. (NEDO)

    Described herein are the results of the FY1994 research program for analysis and evaluation of new storage batteries for photovoltaic power systems. Quantitative analysis and evaluation are made for introduction of intermittent operational mode in the conventional power supply system in which electrolyte units are connected in parallel and for improved performance by bubbles flowing into the line that supplies the electrolyte to the stack, in order to establish the configurations of and operational procedures for the redox flow batteries. The study on development of redox battery compares the Pb-Sn alloy felt collector with carbon fiber, Pb-Sb alloy felt and the lattice for the conventional lead acid battery, in order to optimize the new lead felt battery. As a result, it is found that the Pb-Sn alloy felt collector is better than any other device tested, because of its higher freedom with respect to electrode shape and battery size. The study on reliability evaluation of amorphous solar cells tests photoelectric conversion efficiency of a-Si solar cells, in order to elucidate the phenomena where degradation and rejuvenation compete with each other under weak light irradiation conditions. 8 figs., 1 tab.

In fiscal 1999, in the study of highly durable materials for solar cell modules and of their structure, a thin film compound solar cell module was enlarged to 82cm times 71cm, evaluated for performance, and installed on the third test house. In the study of collecting AC power from the solar cell module, a compact power conditioner for a roof panel which had been in test operation on the roof of the laboratory since 1998 was checked for practical performance, improved, and evaluated for system generation efficiency. In the study of a highly durable roof module structure, problems pertaining to heat radiation from the rear side steel sheet, the burning of the junction box, etc., were solved, and the module passed a verification test under the Building Standard Law. In the validation of the roof module for which power generation performance and meteorological conditions had already been continuously measured for 19 months, it was found that the roof module suffered no troubles such as water leak or deformation.

    Research is conducted to properly deal with environmental problems, such as compromised solar cell safety, which may follow the mass introduction and diffusion of photovoltaic power systems. In the research of fiscal 1999 on technical literature on environmental measures against lead and animal tests, a need was found to reduce lead in power systems and to grasp lead elution characteristics for the establishment of environmental measures. In a safety test conducted for thin-film CIS (copper indium diselenide) based solar cells, basic data were collected about the vaporization rate of Se, the effect of moisture on the Se vaporization rate, etc. Basic data were also collected about the relationship between the combustion temperature and the amount of scattered lead in particular from the solder used as the conducting material in silicon based solar cells. In the evaluation of the environmental impact of thin-film CIS solar cells in case of fire, it was found that Se concentration below 10-20m in the plume was near the permissible concentration of 0.1mg/m{sup 3} as recommended by Japan Society for Occupational Health and that the concentration levels predicted for the periphery were two orders of magnitude smaller than the mandatory level.

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

    This paper discusses hydrogen fuel cell systems. In the economic performance of fuel cells, the ratio of fuel cost accounting for in the power generation cost is as very high as 66% or higher to 82%, if hydrogen unit cost is in the range of 20 to 50 yen per Nm{sup 3}. Enhancing the power generation efficiency contributes more greatly to reduction of the power generation cost than by reducing the construction cost. There should be no much influence on the power generation cost if a system lasts four to five years. The paper also discusses the discrete type power generation system. Discussions were given on a waste heat recovering fuel cell system using as the model an office building of 16 stories above the ground, with one basement and a total floor area of 16,000 m{sup 2}. If the system can be constructed in such a way that the fuel cell capacity is made slightly larger than that corresponds to power load, and whole air conditioning load can be taken care only by waste heat by using a heat pump, the auxiliary heat source can be made smaller, and the overall fuel conservation ratio can be larger, thus the fuel was found saved by 40% than in existing systems. In using hydrogen in automobiles, weight problem will emerge if high-pressure hydrogen or metallic hydride is used for hydrogen storage. Liquefied hydrogen is light in weight, but large in volume. Development is desired on high-performance hydrogen absorbing alloys. (NEDO)

    This paper describes research on peripheral technologies for hydrogen. For the cost of manufacturing hydrogen from different primary energies, coal gasification could be the lowest at the present time. In the nuclear power field, the thermo-chemical method and the water electrolysing method may be assumed, but they depend greatly on future technological development. Particularly the water electrolysing method is dependent on electric power cost. In the hybrid method, hydrogen is obtained from electrolysing reaction with water of sulfur dioxide derived by paralyzing sulfuric acid (oxygen is also generated). The method requires two forms of energies, heat and electric power, whereas combination with a very high temperature reactor (VHTR) is being discussed as a heat source. This method may not be said greatly more advantageous than the direct water electrolysis, but may have future possibility. Hydrogen manufacturing utilizing living organisms is an interesting matter in terms of science and engineering, with a large number of research achievements beginning to appear. Expectation is drawn on the mechanism based on co-work of photosynthesis and a hydrogen generation system, alga and bacterium strain search, separation, cultivation, and applied research and development. Research is also under way to obtain hydrogen by converting photo-energy by using an electrochemical photo-cell utilizing semiconductor electrode to electrolyse water (color sensitizing) (NEDO)

    It may be intended that CWM is manufactured in areas near coal producing areas in overseas countries and imported as a product requiring lower handling cost than in bulk products. In order to achieve this idea, it is necessary to establish a distribution and relaying system for product transportation inside and outside the country, including relaying bases for receiving, loading and storing the product. This paper reports results of the demonstration tests performed since 1992 to 1996. In the tests, CWM made from Chinese coals was transported from Shijiu Port to the Hibiki relaying base in the city of Kita-Kyushu on 5000 DWT ocean vessels, unloaded, stored, and loaded again on 700 DWT domestic vessels for distribution to users. Since the inauguration of transportations, 40,000 tons of CWM were delivered yearly to the Okayama plant of Tayca Company, and about 20,000 tons to the Mizushima power plant of the Chubu Electric Power Company over a period from 1995 to 1996. During the period, a number of findings were acquired in different aspects, including quality control of incoming and outgoing CWM, stability in quantity and properties, loading and unloading works, and transportation. Although reduction in subsidence during transportation and storage was indicated desirable, the practical applicability was verified for the relaying system as a whole. 4 refs., 15 figs., 3 tabs.

    This paper introduces two out of six theses related to hydrogen fueled aircraft engines presented at the First World Hydrogen Energy Conference held in Miami in March 1976. One thesis mentions several initial prospects related to terrestrial requirements on hydrogen fueled transport aircraft. Liquefied hydrogen is attractive for large long-distance transport aircraft. Its high energy content can reduce the take-off full load weight by more than 30%, enhancing the economic effect of the aircraft. Saving fossil fuels will require national policy decisions in the near future, where introduction of liquefied hydrogen is more advantageous for long-distance aircraft. However, its introduction into wide-body transport aircraft being the major consumer requires transportation companies and airport authorities to carry out joint development with transport aircraft makers and liquefied hydrogen suppliers. The second thesis describes special natures of fuel subsystems for liquefied hydrogen fueled aircraft. Requirements to major fuel system elements and operation characteristics require evaluation as a comprehensive system, rather than as individual component criteria. In addition, hardware, experience and fuel systems as they are now in space development may not necessarily serve for the purpose. (NEDO)

    This paper discusses hydrogen fueled automotive engines. Because hydrogen has a very wide ignition mixture ratio limit for spark ignition engines, very lean combustion is possible without a need of throttling, and thermal efficiency in partial load is high. Thermal efficiency while a car is being driven is reportedly higher by 30% to 50%. Values for CO and CH in exhaust gas are negligible, while NOx is at about the same degree as in gasoline engines, which can be made extremely low during lean burn operation. The spontaneous ignition temperature is higher by about 200 degrees C than that of light oil, which presents difficulty in use for diesel engines. Because of small ignition energy and high combustion velocity, excessively early ignition and reverse ignition can occur easily. Hydrogen would be promising if new manufacturing systems are developed and production cost is reduced, and on the other hand, if petroleum price rises sharply. Hydrogen is also expected as a measure to prevent pollution, including that from soot, odor and CO2. The largest difficulty is in the transportation method, and the only possible method at the present is transportation in liquefied hydrogen form. However, practical application will have such problems as tanks, feeding devices, and cost. Development is desired on light-weight metallic hydrides. Technologies for safety and engine performance must also be developed. (NEDO)

    Described herein are results of survey on brown coal liquefaction techniques and peripheral techniques, centered by COSTEAM process under development in USA, solubilization by alcohol and liquefaction and cracking with the aid of tetrahydroquinoline as the hydrogen donor under development in Japan, and low-temperature carbonization and new promising techniques. The COSTEAM process shows higher reaction rates, conversions and oil yields for brown coal liquefaction than the one using hydrogen gas. Some of the problems involved in this process high viscosity and oxygenated compound content of the product oil. The product oil is acceptable as fuel for power generating plants and can be produced at a moderate cost, but may be unsuitable as vehicle fuel. Coal liquefaction and solubilization processes are mainly represented by those which use hydrogen. The hydrogen cost, which is high, determines the product price. The processes which use alcohol or tetrahydroquinoline are still in the experimental stage. (NEDO)

    This paper describes chlorination substituting disinfection technologies used in water purification systems. Chloramine treatment is regarded as effective in reducing trihalomethane (THM). Chlorine is injected in the initial stage in the form of free chlorine to disinfect pathogenic microorganisms in a short time, which is then added with ammonia to convert it into chloramine for further utilization. Chlorine dioxide has not been used in Japan, but introduced in Europe and America to treat THM. Ozone has the strongest oxidizing power, and is used for disinfection, virus inactivation, decomposition of THM precursors, and removal of fungus odor. The ozone treatment will produce aldehyde if an organic matter is present, but aldehyde can be removed by treatment using organismic activated carbon. Ultraviolet ray treatment has an advantage of being difficult of producing byproducts. This system was experimentally compared with free chlorine treatment on disinfection effect, mutagenicity, suppression of producing THM byproducts, and odor removal. In order to assure reliability of microorganismic and chemical safety in tap water supply systems, assurance by considering the entire system is important, not only by operating the disinfection units, but also combining such physical water purifying technologies as coagulation, sedimentation, filtration, and membrane treatment. The use of chlorine substituting disinfectants is also a part of the conception. 6 refs., 8 figs., 5 tabs.

    Observations are being made in Takasaki City, Gunma Prefecture on insolation, putting emphasis on the north side, and insolation by wavelengths to put insolation estimation model on the north side slope into order. This is an attempt to put into order by using the model the data for insolation on slope in all azimuth, taking the meteorological offices all over the country as the object. With regard to monthly average insolation, it was verified that the existing estimation model can be applied to the north slope in the Takasaki area, whereas trial calculations were performed on the average daily cumulative insolation by azimuth and inclination angle in the Takasaki observation points. As a result, it was made clear that the insolation onto north side roofs in Japan is about 70% of that on the south side. With respect to the time cumulative slope insolation, it was made clear that the Perez's cumulative model can be applied to the Takasaki area. Spectral distribution of global and scattered solar radiation was put into order by insolation to have verified that the stronger the global solar radiation intensity, the greater the occupation ratio of shorter waves increases, or in other words, the spectral distribution of the global insolation can be formulated. Sky distribution of radiation is being measured by means of measuring the sky scanning type radiation and luminance distribution. (NEDO)

The joint study with an Indonesian research institute takes a model of lumber drying plant for the design and feasibility study. All the parts it needs are technically available in Indonesia, except carbon fiber sheets and electronic devices for controlling purposes. The drying cost is higher than that of a plant which procures charge-free wood fuel, but lower than that of a plant which procures fuel at 30$/t. A cacao drying plant model is also studied. The feasibility study shows that the initial investment for the blowing-up model is much higher by 60% to 100% than that for the conventional plant. Its fuel cost is lower by 11% than that of residual oil but 27% higher than that of wood. 4 figs.

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

    The present report introduces the technological trend of rainwater drainage information system mainly with radar rain gauges. The information network must be strengthened as measures against the urban flood from the rainwater drainage. A radar rain gauge-based combination is needed of synthetic and organic processing technologies covering the traveling prediction of rainfall, data communication and rainwater drainage/flooding prediction. The correction method and data communication/display technology are explained for the measurement with radar rain gauges. In both correlation function method and rainfall area pursuit method, the traveling of rainfall is predicted by utilizing the radar information for the sewerage system. For the drainage analysis, it is necessary to quantitatively estimate the rainwater drained into both main and branch sewerage lines. It is made by preparing a rainwater drainage model. The quantitative estimation of rainwater drained into the branch sewerage lines calls for a revised Road Research Laboratory guidance by the Ministry of Construction. Supplemented with knowledge by veteran operators, the displayed image of pump operation support system is simulated for its verification. 2 refs., 3 figs.

    While a cement manufacturing process generally performs sintering by using a rotary kiln, a development work has been carried out as a subsidy operation of the Agency of Natural Resources and Energy on a cement sintering technology using a fluidized bed consisted of two furnaces: a jet flow bed granulating furnace and a fluidized bed sintering furnace. This paper reports the results of tests and researches performed during fiscal 1995. A plant with a scale of 20 ton-a-day production started in 1993 after having gone through bench scale tests. The year 1995 conducted by August its performance evaluation, review of the operation method and the safety criteria, and generalization of the tests. A multi-stage cyclone system has been employed in the preheating equipment for cement material powder. A number of improvements have been realized in the aspects of construction and operation, such as stabilization of dust collecting efficiency by employing a high-efficiency type cyclone, and operation with reduced pressure variation. Based on these results, a construction had been progressed in parallel on a new plant upscaled to 200 ton-a-day production. The new plant was completed in December, 1995. 9 figs., 8 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.

    The software of automotive control systems has become increasingly large and complex. High level languages (primarily C) and the compilers become more important to reduce coding time. Most compilers represent real number in the floating point format specified by IEEE standard 754. Most microprocessors in the automotive industry have no hardware for the operation using the IEEE standard due to the cost requirements, resulting in the slow execution speed and large code size. Alternative formats to increase execution speed and reduce code size are proposed. Experimental results for the alternative formats show the improvement in execution speed and code size. 4 refs., 3 figs., 2 tabs.

    Described herein are the results of the FY1994 research program for energy conversion technology using chemical reactions by the aid of solar energy. The demonstration runs were conducted by a bench-scale unit, which was operated stably for 100h, to produce promising results. The catalyst exhibits stable performance, without showing a sign of deactivation. It is found that the heat pump system works well, without being interfered with accumulated by-products. A heat of approximately 2,100kcal/h is recovered. It is confirmed that steam of 150{degree}C and 200{degree}C is generated from hot water of 80{degree}C and 95{degree}C, respectively. The bench-scale runs show a thermal efficiency of around 10%, which is lower than the target level. However, the runs with hydrogen-occluding alloy attain a process thermal efficiency of 30%. The system in which solar collector and chemical heat pump units are combined is evaluated with respect to its economic efficiency and operability for its eventual commercialization. 6 figs., 2 tabs.

    An acorn type concentrator is a 2-dimensional system and realizes relatively high magnification power, but it requires a special assembly process for modularization because the cells and the concentration system are quite small. Under the circumstances, studies are conducted on a prism array concentrator (PAC) which will demand a smaller burden for modularization. A PAC system is basically a 1-dimensional concentrator in terms of light collection performance. The cell to be attached to one plane in the longitudinal direction of the long triangular prism is so small as 5mm in width, yet it may be as long as 50-100mm, and the conventional flat plate assembly process may be made use of. A concentration efficiency of 82% and a conversion efficiency of 10.9% were obtained from a minimodule with a light intercepting area of 5cm times 4cm. Furthermore, a conversion efficiency of 19.7-21.4% was obtained when a small 5mm-wide cell applicable to a PAC type concentration was used. Since a prism type concentrator optical system will cost much for its molding and strengthening when it is built of glass, inexpensive EVA (ethylene-vinyl acetate copolymer) was utilized as an adhesive filler.

    These technological developments are intended to develop technologies to manufacture with improved quality the silicon-based thin film solar cells. In order to analyze manufacturing conditions for micro crystal silicon thin films as the narrow-gap amorphous silicon-based films, films were manufactured in the vicinity of borders of amorphous/micro crystal silicon film manufacturing conditions. The present film manufacturing did not present effects of suppressing deterioration of hydrogen diluted light. In order to elucidate the light deterioration mechanism in hydrogenated amorphous silicon films and study the suppression thereof, discussions were given on impurities in the film, including oxygen. By using an ultra high vacuum plasma CVD having a thoroughgoing baking system, an oil-free exhaust mechanism, and a raw material gas refining mechanism, impurities were added to and removed from a reaction vessel, and an ultra-high purity Si:H film was manufactured, which has been removed of impurities from the raw material gas, resulting in reduction of O, C and N standing no comparison. According to the result of a light irradiation experiment on an ultra-high purity film obtained under an accelerated deteriorating condition by using a pulse laser, the model assuming the light induced defect and the pair of impure atoms has been denied.

    The project intends to improve on large-area amorphous silicon solar cell performance and to develop high-throughput manufacturing technologies for a reduction in the cost of modules. A film substrate type amorphous solar cell structure of the serial connection type named SCAF (series-connection through apertures formed on film) is contrived. Under this method, film formation using a stepping roll system newly developed for glass substrates may be applied, and the number of manhours required is allowed to be less than under conventional serial connection forming processes. The new technique is characterized in that serial connections are established via through-holes provided in plastic substrates. Making use of the technology, progress is attained in the development of high-throughput process technology for film substrate type amorphous solar cells and of efficiency enhancement technology. In fiscal 1997, an electron beam unit for plasma generation aiming at the elucidation of reaction processes in plasma was introduced, and technologies based on the equilibrium discharge technique were developed enabling high-speed a-Si film formation without degradation in film quality. The effect of trace boron addition to the tandem cell bottom I layer was investigated, and a stabilization rate of 8.05% was achieved using a 40cm times 80cm large SCAF cell. In fiscal 1998, endeavors were exerted for similar developments. (NEDO)

    Research and development of a lavatory training system is carried out to enable bed-ridden aged people to evacuate unaided and thereby to elevate their consciousness of self-reliance. The developed system consists of a multi-functional bed with a built-in transfer unit and a movement assisting system. The multi-functional bed consists of a device that automatically transfers the patient abed to a position on the bedside portable toilet, a device that is remotely controlled to change the posture of the patient from the in-bed state to a seated state, and an audio-visual system that encourages the patient into self-reliance. The movement assisting system enables a patient, who needs people's help in rising from the bed and in walking to the lavatory, to stand up, sit down, and walk, all unaided. The system has undergone field tests at 6 locations in hospitals, public facilities, and residential houses. The result is that for people of Category III it is almost certain that they can travel safely thanks to the system. The system is again evaluated high in barrier-free residential environments.

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

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)

As to the utilization technology of gut symbiotic microorganisms such as termite and longhorn beetle, clone types of gut microorganism complex system were analyzed to find out the diversification. In the decay of wood, co-culture of two species of mold fungus was increased in efficiency than single culture. More than 90% was classified/identified of the mold fungi accumulated (in wood piece)/separated for the utilization of plant symbiotic microorganisms. For the production of petroleum substituting useful resource, conditions were established of callus induction from immature embryos of tropical oil crops, especially oil palm, and of regeneration of a lot of small plants from the callus. To establish the Agrobacterium-mediated transformation system of oil palm, the binary vector harboring the reporter gene and selectable marker gene was constructed. Using the vector, oil palm tissues are inoculated and infected with agrobacteria. To heighten the function of palm oil, 10 particular clones were selected from the complementary DNA library obtained from oil palm fruit tissues. The genetic study of germs was also made. (NEDO)

    With an objective to prepare a strategic technological development program for solar heat utilization, evaluations and discussions were given on solar heat utilization from the viewpoints of 'utilizing applications', 'demand' and 'possibility of the proliferation thereof'. In the solar heat utilization, the cost rising in approximate proportion with scale of the heat utilization must be considered as one of the predestined conditions. What can be conceived as a means to enhance the economic performance by using engineering approaches would include heat storage, elementary technologies for transportation and the standardization thereof, and the scale economy on the production side in mass production. As a required step in which the series of favorable circulation of standardization to mass production, cost reduction and large quantity proliferation can be induced, it is appropriate to assume household use with high calorie unit price as the target. The household area covers room heating and hot water supply, in which the temperature level is much lower than in industrial use. In this area, a system may be established with a conception to use solar heat as the main heat source, and calorific power by fossil fuel as the supplementary heat source.

    Interconnecting photovoltaic systems with power transmission systems under high density affects power quality, protection, maintenance and stability of the transmission lines. As measures to deal with this issue, investigations are being made on (1) elucidation of effects imposed on transmission lines, (2) establishment of countermeasure technologies, and (3) technological options leading to higher value addition. In Item (1), with an objective to identify the current status, evaluations were given on prevention of independent operation of commercially available inverters, and on their stabilizing performance against system fluctuation. The evaluations were performed by conducting a test for multiple unit operation in parallel and a single unit performance test. The test result indicated that, while the prevention performance can be satisfied, maloperation has occurred frequently due to the system fluctuation, and that voltage rise due to the inverter was suppressed effectively by using the simultaneous control of active and reactive powers. In Item (2), a demonstration test was launched on an inverter incorporating a new prevention device. The effective means to suppress voltage rise in the high-voltage power transmission lines is the discrete voltage suppression by controlling reactive power. In addition, a proposal was made on a new voltage and phase detection method that can be used at short circuit of the high-voltage transmission lines. In Item (3), having a photovoltaic system contain a small size batteries was found effective in suppressing the power generation output variation, and in smoothing the loads. (NEDO)

    Described herein are the results of the FY1994 research program for solar/energy-conversion technologies retrofitted to existing buildings. The estimated effects and economic viability of retrofitting technologies show that they bring very high energy-saving effects when applied to heating and hot water supply, which consume a large portion of energy, but relatively low energy-saving effects when applied to cooling, solar walls, glazed balconies and transparent insulators. The study on applicability of these technologies in Japan indicates that the technologies which can recover cost within an average life time are those applied to windows, solar collector systems for hot water supply and heating, and transparent insulators. Although these technologies are low in applicability to cooling viewed from the angle of cost recovery, retrofitted radiation type cooling systems improve not only cooling and energy-saving effects but also comfortableness.

    Solar technology and energy conservation technology (through retrofitting) which can be introduced into existing buildings are evaluated for their effect and economic efficiency. Studied are technologies verified to be technically feasible at the current stage, introducible into existing buildings without major modification, low in introduction cost, and high in energy conservation effect. How retrofitting technology should be in Japan is discussed. In Japan where demand for heat is smaller than in Europe or America and building service life is shorter, conditions to meet for efficient cost recovery are quite severe. Suitable measures to enhance cost recovery include use of multiple panels of low-radiation glass and light modulators for windows and use of collecting technologies such as solar systems for hot water supply and air solar collectors. Use of a transparent insulator is also recommended. Japanese houses demand repair and reconstruction very often, which helps cost recovery. Dependence on locality is extensive, and this causes difference in solar system application.

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

    The solar energy utilizing technologies having been developed under the Sunshine Project were used to have executed the international joint technology development on the 'solar heat utilizing drying system' in the Republic of Indonesia. This paper summarizes the achievements in fiscal 1998. In operating the pilot plant, three operational experiments out of seven experiments were carried out only by Indonesian engineers. As a result of the drying experiments, the heat collecting characteristics of the collector were as about half at 19 to 30% as the efficiency assumed in the design of 50%. The reason for this can be attributed to the fact that the cover glass used in the demonstration test in Japan had light permeability of about 87%, but the cover glass used in the test plant was made of frosted glass whose light permeability was about 37%. This glass is the only glass available for a heat collector in the solar heat hot water device in Indonesia, but is unsuitable for the heat collector. Another cause was that the insolation at the site was lower by about 30% than the one used at the design stage. (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)

    The Automatic Sewing System Technology Research Association was commissioned from the Agency of Industrial Science and Technology on the 'development of an automatic sewing system'. The association is performing the research and development by dividing the subject into such component technologies as a total system and sewing preparation and processing technology, a sewing and assembling technology, a cloth handling technology, and a system management and control technology. This paper reports the achievement of the research and development on the system management and control technology. Plans have been established on the following items: dimensional inspection of sewn parts by using an image processing technology, real-time processing of the matching work interlocked with a striped pattern cloth handling device, and a processing positioning algorithm to instruct sewing lines and needle dropping points based on contour lines of pockets and collars. The effects thereof were verified. Printing seven-segmented numerals on cloth by using fluorescent whitener and an automatic reading test of the printed information verified that the technology can be applied to tracking the parts in a processing line as an ID information. Researches were also made on unification of micro-computers for controlling such automatic machines as a multi-functional sewing machine, a three-dimensional sewing machine, and a cloth handling and positioning device, as well as on interface with the computer for function sharing management and control.

    This paper describes the achievements in fiscal 2000 from the WE-NET Phase II for Task-4, the development of a motive power generation technology. The objective is to build a 100-kW class single cylinder hydrogen-argon circulating diesel system. For a hydrogen injection valve being the key to the system, development was made on the conventional hydraulic system with quick compression, expansion, and electronics control. Discussions were given on an exhaust gas condenser and a gas-liquid separator to handle gas mixture with low steam concentration. In order to assure the mechanical strength to deal with the argon working gas, super-chargers and expansion turbines were also discussed. When the hydrogen injection pressure is increased from 20 to 25 MPa in the basic test, the combustion speed has increased, and the indicated thermal efficiency has been improved. The same effect was obtained also when the oxygen/argon ratio was increased. Although the thermal loss increases if the oxygen/argon ratio is increased, the loss in the indicated thermal efficiency is compensated by the gain derived from increasing the combustion speed. When argon is used as the working gas, the temperatures in parts of the combustion chamber rise much higher than that in the case of a light oil diesel system. Therefore, discussions were given on materials and structures that can withstand elevated temperatures, and assessments and tests were performed on high-temperature lubricants. (NEDO)

    As a part of the WE-NET project, the tanker for liquid hydrogen transport was studied. In fiscal 1996, some experiments and numerical analyses were proposed which are necessary to solve technological issues extracted in fiscal 1995 for heat insulation structure. The issue was roughly classified into vacuum and non-vacuum insulation, and their basic functions and required performance were arranged. Boil-off rate of 0.2-0.4%/d was targeted. The insulation system which applies polyurethane form (PUF) to tank surfaces and injects atmospheric N2 gas into the surrounding hold space, could achieve the targeted insulation performance by PUF of 1m in thickness. The system of vacuum panel insulation and atmospheric N2 gas injection into a hold space required the panel of 500mm in thickness because of the large effect of metallic outer panel material. The system of vacuum hold and PUF panels was faced with the essential issue for realizing and maintaining vacuum hold. The super insulation system featured by layered insulation materials and vacuum layer spaces was also strongly affected by degree of vacuum. 23 figs., 8 tabs.

    In order to identify the possibility of a hot rock power generation system, technological R and D has been performed on structuring of a man-made hydrothermal system, fracture mapping, downhole measurement and a circulating extraction system. This paper summarizes the achievements in fiscal 2000. With regard to the long-term circulating extraction test, a circulating heat extraction and test device was installed at the hot rock experimental field in the Hijiori area in Yamagata Prefecture, where geochemical data collection and tests including analyses thereon have begun. In reservoir bed analysis, a well module was incorporated into a reservoir bed simulator to improve the module so that comparison with the data of actual production on the ground can be performed. For the fracture mapping, AE having been observed during the long-term circulation test was analyzed, whereas it was estimated that the seismic source would not move or expanded during this period. A PTS logging has been performed during the long-term circulation test to investigate characteristics of the flow-out zone of the injection well and the production zone of the production well. In making the fracture model, an initial model was fabricated to estimate heat extraction behavior in the long-term circulation test. (NEDO)

    Low-cost monosilane production technologies are studied for film formation on amorphous solar cells. In fiscal 1984, the monosilane generation system modified in the preceding fiscal year is subjected to an extended operation for stability test for improvement on the process. The purity of monosilane produced during the stability test operation is found to satisfy the target level, and this means that the system operates at high efficiency. As for electrolysis, important problems arise with detriment to the practical application of this method. Though a solution is found for each of the problems, yet the problem of how to prove their effect remains to be solved. As for technologies for monosilane purity evaluation, a CVD (chemical vapor deposition) proving furnace is built, and research is started as to how to perform purity estimation using the characteristics of silicon layers epitaxially grown on high-resistance silicon substrates. The monosilane is examined, and it is found that its has a spreading resistance of 1,000 ohm-cm against the 2,000 ohm-cm of monosilane available on the market. Since the characteristics determined in this way are greatly affected by the conditions set for CVD, it is necessary to make further efforts to enhance optimization. (NEDO)

    The goal is to develop basic technologies to build an SiC device capable of service amid high-temperature surroundings for the advancement and optimization of combustion control systems. In an SiC semiconductor, the Si-C bond is broken when irradiated with ions, and this makes the occurrence of thermal oxidation easy to occur. In the study to form SiC into single-crystal substrates, a substrate with warpage of 10 micrometers or less and surface coarseness of 10 nanometers or less is realized. In the development of sensor technologies, the high-speed CVD (chemical vapor deposition) method is applied for the growth of crystals further on a 3C-SiC layer epitaxially grown by MBE (molecular beam epitaxy) surface control, which improves on layer characteristics. Element technologies are developed for the construction of a 3-terminal element (FET: field effect transistor), which is for the construction of a high-temperature, high-speed SiC device. An effort is made at achieving 3C-SiC hetero-epitaxial growth, etc., on a 3-inch Si substrate using an SiC crystal film formation experimenting apparatus, which aims at constructing a control device. Concerning the combustion control system, the relations between the air/fuel ratio and the emission spectra of radicals OH, CH, and C2 in a flame are made clear. Also referred to are the basic studies being conducted at research institutes such as universities and a survey of technological trends abroad.

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

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

    NEDO is proceeding with the development of a technology to put photovoltaic power generation system for industrial use into practical use, with an aim of simultaneous solution of sustainable growth and environmental problems. In developing an advanced heat process type system, selection was made on high-performance refrigeration materials for a stand-alone type refrigeration system capable of dealing with levels of minus 20 degrees C or lower (Ti-Ni-Zr-Mn-V based hydrogen absorbing alloys for use at low temperatures, and La-Ni-Sn-Al based hydrogen absorbing alloys for regeneration use). Evaluations were given on the developed refrigeration system by using the dynamic property simulation technology. The developed system achieved a cold heat acquiring temperature of minus 20 degrees or lower, and a heat output of 1,500 kcal/hr or more under the conditions of outside air temperature of 28 degrees C, and collected solar heat temperature of 140 degrees C. CO2 reduction unit requirement was calculated from LCA on a solar heat utilization system with which the future technological development is expected to aim at. Themes proposed to be promoted in the future would include a direct heat utilization system such as the building material integrated system, a freezing and refrigeration system, a high-temperature light and heat collecting system, a harmful substance analyzing system, a high temperature utilizing fuel synthesizing system, a high-efficiency heat storing system, and a snowy cold region system.

    The project aims to evaluate the results so far achieved in 'The research and development of ITS (intelligent transportation system) by use of clean energy vehicles' and 'Research and development of ITS technology assisted mobility systems' and the development systems under which the efforts are exerted and to evaluate the possibility of their practical application and the spread of the effects brought about. Ex post facto evaluation is conducted of two types of test systems. The first type includes a rent-a-car for business use in the urban area, a rent-a-car for sightseeing, and a system which is an ITS provided electric car as a domestic second car in the residential district. The second type includes a shuttle bus park-and-ride system and a natural gas fueled physical distribution truck. The result is that the ITS provided electric car system is evaluated high by evaluation committee members. The score lowers in the order of the system for business use in the urban area, the system for sightseeing, and the second car system in the residential district. An electric car reduces its environmental impact when it uses a power generation system that utilizes renewable energy. It has become clear that high convenience will be achieved when a dispatching system is improved for a combination of a 'subminiature electric vehicle and ITS technology' as a method to satisfy the demand for commutation means in case the clientele is one or two people.

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

    This paper describes the sewing preparation and processing technology from the achievement report for fiscal 1986 on developing an automatic sewing system. For the cloth property evaluation technology, such devices were used to measure different kinds of cloths and evaluate cloth properties related to sewing performance, as the KES testing machine, the measuring device for composite transformation, large transformation and bending, and composite surface properties, the cloth air permeability testing machine, and the thermal property measuring device. The system was verified with regard to data banking to confirm feasibility of the system to practical application. Among the cloth stabilizing technologies, discussions were given on age-based stability of cloth properties, repetitive transformation resistance, temperature, hardener deposition amount, and bending rigidity in cloths treated with temporary hardening agents. Discoloration, robustness and device damaging effect of cloths were also investigated. A partial and temporary hardening device was fabricated to make partial hardening possible. A continuous deflocculating device was also fabricated making deflocculation of temporarily hardened cloth possible. The deflocculation was discussed on the sewing process in relation with workability, and it was revealed that low-level hardening treatment is effective. It was verified that the handling is facilitated particularly in cloths that tend to curl. (NEDO)

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

    R and D was conducted concerning intermediate processing technology for recycling mixed waste plastics, a technology for processing household waste plastics such as plastic containers and packaging into plastic pellets of suitable grain sizes, with fiscal 2000 results compiled. In the development of the element technologies, an air clutch structure was added that generates rotor slip when foreign matters were engaged, thereby unnecessitating pre-sorting work for locating and removing metallic foreign matters. Addition of an air separator and a sieving machine also helped to achieve a useful-plastics recovery rate of 75% or more in the PVC separation equipment. In the operation of a demonstration plant, a continuous operation was carried out in a three-shift 24-hour system for five days, with the data obtained. Further, waste plastics to which the Containers and Packaging Recycling Law was applicable were treated, resulting in the processing capacity of 0.51 t/h and the production capacity of 0.38 t/h, which both exceeded the target. In the evaluation of the intermediate processing system, the cost of waste plastics treatment turned out to be about 50,000 yen per ton in the case of a plant having a processing capacity of 6,000 tons per year and about 30,000 yen per ton in the case of a plant of 24,000 tons per year.

    For the preparation of a proposition concerning future research and development, surveys and studies were conducted centering about efficiency enhancement and cost reduction for the next generation ultrahigh-efficiency solar cell system. For improving the efficiency of the crystalline compound solar cell, studies were made about the prospects of the embodiment of a 3-junction and 4-junction types and of an increase in conversion efficiency expected to realize thanks to their light condensation behavior. It was inferred that anticipation of 29-47% conversion efficiency in 1 to 4-joint cells was theoretically acceptable. Four-joint structure cell fabrication would be a challenging task but would bring about an conversion efficiency of approximately 47% thanks to enhanced light condensation capability. As for cost reduction through the use of light condensation technology, surveys of overseas trends showed that the condensation-enhanced photovoltaic power system was characteristically fit for lower-price production. As for condensation and tracking systems, studies were made about cost calculation models of organizations involved in the United States and Europe, and then it was found that cost reduction in the optical system for condensation and in the tracking mechanism would be mandatory for the achievement of 75 yen/W.

    Studies have been made on preparing criteria for the safety assuring technologies for hydrogen energy total systems. The outline of the technological guideline for hydrogen manufacturing processes in the high temperature and pressure water decomposition method is the same as that in the normal pressure water decomposition method. However, its high temperature and pressure environment can cause new safety problems. Considerations should be given on, for example, material problems in structural materials and insulation materials including electrodes and membranes, introduction of gas-liquid separation and pressure balancing devices, problems in electrolyte circulation, and safety problems that may occur because of generation of hydrogen and oxygen under high temperature and pressure conditions. This paper summarizes these matters by surveying literature data. In order to provide basic information to prepare criteria for safety assuring technologies for the gaseous hydrogen liquefaction process, surveys and studies were made based on different items of technological information and experimental study results. Safety assuring technologies were discussed on metal hydrides (promising means for storing hydrogen). Powder is used to enhance hydrogen absorbing performance, whereas the metal hydrides are pulverized as a result of repetition of absorption and discharge of hydrogen. This paper describes also metal dust explosion disaster and its risk of occurrence. (NEDO)

    From the sonic prospecting on the ground, it was confirmed that faults distributed in the inner part of Suruga Bay extend near the Fujigawa river mouth. While, faults in the sea bottom were found by the sonic prospecting using a single air-gun. However, continuity of faults running from the land to the sea has not been reported. This paper describes the continuity of Fujigawa fault system running from the land to the sea around Fujigawa river mouth along the subduction zone of Philippine Sea Plate using single air-gun seismic reflection records. Locations of the faults can be expressed as fracture information of linearment obtained from the satellite remote sensing images, which agreed well with those found by the Active Fault Research Association. As a result of the image processing, they agreed distinctly with the topography of Fujigawa fault system. Thus, much more accurate analysis can be performed by comparing the regional information by the remote sensing with the sonic seismic reflection profiles. 3 refs., 2 figs.

    Feasibility was studied of a demonstrative research concerning effective operation of a hybrid system consisting of photovoltaic, wind and diesel power generations in Myanmar. Upon confirmation of Myanmar's request and assistance, Myanmar electric Power Enterprise was selected as the counterpart, with Kantangyi village determined as the candidate site from the viewpoint of the quantity of solar radiation, wind conditions, and convenience in transportation service. Meteorological observation instruments were installed at Nyaung U observatory, with the observation implemented. It was grasped that the demand spreading pattern and the demand for electric power was 40 kWh/month per household. It was also judged that the system structure should be constituted of photovoltaic power, wind power, and diesel generator/battery/adjustable load. The problems are stable supply technology, technology for effective use of renewable energy, technology for complementary effects of photovoltaic power generation and wind power generation, and demonstration of a 100 kW class wind power generation system. Particularly important is consistency between the capacity of power storage equipment and that of diesel power generation. The study results applicable to Japan is the verification of a small-sized independent system for remote islands or the like. The total research expenses were estimated to be 600 million yen. (NEDO)

    This R and D project is for the preliminary studies on development of the following 4 types of techniques for developing resources from gas-hydrates (GH): (1) gas-hydrate exploration, (2) excavation techniques, (3) methods for assessing environmental impacts, and (4) gas hydrate handling systems. The FY 1988 R and D results are described. For gas-hydrate exploration, the methods for analyzing inorganic ions and trace quantities of elements, which are necessary for accurately estimating the offshore GH around Japan, are established; and case studies are conducted for methods of predicting GH deposit forming mechanisms, and stability fields of GH, based on terrestrial heat flow and seismic data. For excavation techniques, GH decomposition rate is analyzed using a laboratory system which reproduces conditions of excavation of GH layers. For methods for assessing environmental impacts, a geo-hazard predicting model is established, to study ground displacement and gas leakage sensing systems and data transmission systems to cope with the hazards. For gas hydrate handling systems, an overall system is studied, and storage and transportation systems are outlined. (NEDO)

    For the purpose of supporting the study of commercialization of thin film solar cells for electric power use and the study of production technology of thin film solar cells, survey of the technical trend of the thin film solar cell was conducted, and the FY 2000 results were summed up. The typical Si system thin film solar cell is the amorphous Si solar cell, and the quantity production has already started in Japan and abroad. Further, with the aim of making use of characteristics of the amorphous Si solar cell and also making its defects up, the development of Si thin film solar cell using microcrystal Si and polycrystal Si is greatly expected. Among those, attention is paid to the hybrid type that was proposed for the remarkable improvement in the conversion efficiency of amorphous Si solar cell. In the compound thin film system, the Cu(InGa)Se{sub 2}(CiGS) solar cell was put on the market as product by SSI, though the market scale is small. Further, as to the CdTe thin film solar cell, trial manufacture of the large area module was made in view of the housing use. In addition, there was seen great progress in the color sensitized cell and organic semiconducting solar cell mainly in the U.S. and Europe. (NEDO)

    The container and package recycling law is fully enforced starting fiscal 2000. Recycling obligation is placed also on plastic containers and packages discharged from households, excepting PET bottles for beverages and soy sauce. Therefore, it is required to establish an interim processing technology to process these materials into shapes easy for re-utilization and transportation, that is a technology to manufacture granules with adequate diameters. The purpose of this research is to develop the interim processing system technology. Design, fabrication and installation were performed on an interim processing system plant (a mixed waste plastic granule manufacturing facility) that can process annually waste plastics of 3,000 tons (0.5 t/h). The plant consists of the following four pieces of equipment: (1) a pulverizer, (2) a PVC sorting device, (3) a granulating device, and (4) a sizer. After the installed interim processing system demonstration plant has been trially operated and adjusted by each device, the whole plant was given the trial operation and adjustment to have verified that all the devices function normally. In addition, in order to evaluate economy of the waste plastics interim processing, the processing cost was calculated and the economic performance was evaluated preliminarily by using the rated electric power setting and trial operation data of each device.

    The efforts center on techniques for optimizing the designing process of the system-on-chip (SoC) which assumes the most important part in the technology involved. An SoC is a system in which most of the system-constituting functions are integrated on a single chip, whose design is growing increasingly difficult to prepare because its circuitry containing complicated functions is growing larger in scale at an annual rate of 58%. Its elements are growing microstructural at a sharp pace, and a very optimum designing technique is required to deal with the development. Under the circumstances, the numbers of engineers and man-hours required to cope with the situation are increasing exponentially. The improvement of design productivity at the present time stays at a low annual rate of 21%. Surveyed are the background, objective, and necessity of the research and development of technologies for the whole designing process consisting of the function designing stage which is of the highest level, the logical circuit designing stage, and the manufacturing process designing stage. Furthermore, the current status, research, and development of related technologies and the status of related patents in Japan and overseas are surveyed. Studies are also conducted about the goals of technologies to be developed and about breakthrough points before achieving the goals, and a development project is assumed and proposed. (NEDO)

    In relation to the basic study of the standardization for hydrogen energy technology and ISO/TC197, the results of the fiscal 1997 survey were summarized. From fiscal 1994 through 1996, in the wide-range field related to hydrogen energy technology, the survey of the present situation of the related standards/laws was made and the needs/subjects of standardization to be studied in the future were extracted. At the present stage, however, it is still early to enter into the stage of discussing the standardization. Therefore, in this fiscal year, only in the field of the storage/transportation/handling of liquid hydrogen, standards/laws abroad and in Japan were comparatively investigated for the basic study toward the standardization. Further, concerning ISO/TC197, studies were proceeded with of the liquid hydrogen land vehicle fueling system interface/fuel tanks/transportation containers/hydrogen fuel product specifications/airport hydrogen fueling facilities. Some are at the stage of drafting the international standard. Three drafts for the new standard were added such as gaseous hydrogen/hydrogen blend vehicular fuel systems, gaseous hydrogen fuel tanks, and basic requirements for safety of hydrogen systems. The standardization is indispensable to introducing the developed technology to the commercialization. 9 refs., 5 figs., 13 tabs.

    Described herein are the results of the FY1994 research program for investigation for popular type snow melting systems using solar energy. Two types of technologies are proposed to utilize solar energy for snow melting in winter and create comfortable environments. One is combined (active plus passive) type, which transfers solar heat it collects by the whole wall surfaces to an attic to heat it totally, and makes the whole roof as a radiator to melt snow. However, heat radiated from the roof is insufficient to melt all snow on the roof, allowing it to remain to an extent that it works as an insulator. The other is active type, which transfers heat it collects by the collector to the heat storage tank, from which heat is extracted in winter for various purposes, including snow melting. Such a system must store heat for an extended period, for which a highly insulating heat storage tank is proposed to balance capacity of heat storage between seasons and building size.

    Experiments were conducted on laser-aided decomposition and removal of chemical substances in liquid phase systems on the assumption that there existed chemical pollutants in wastewater or water after washing burned ash. The aim of the research was to split carbon-chlorine bonds and break benzene rings, the two being the cause of harmfulness, and experiments were conducted using chlorophenol. The photolytic lasers were ArF excimer laser and KrF excimer laser. It was found that the reduction rate of chlorophenol in a water solution under excimer laser irradiation was 1.7 times higher under KrF laser than under ArF laser. For mediums other than water, isopropanol was used, more convenient than chlorophenol in separating organic pollutants from burned ash and the like. In this case, organochlorine compounds were generated at the beginning, but they disappeared when irradiation was prolonged. It was demonstrated that the laser-aided environmental cleaning technology would find a very wide scope of application as an effective photolytic means. (NEDO)

    In developing hydrogen transportation and storage technologies based on the WE-NET project under the theme of the 'development of different common devices', surveys and discussions have been performed on four themes with high urgency. It was revealed that, with respect to the large liquid hydrogen pump, the survey report should be reported on the pump models, motors, reduction of NPSH, and bearings, and that the cryogenic pump technology has a necessity of further development because the technology is biased to pumps for rocket with high head. With regard to the vacuum heat-insulated piping with large diameters, such strict problems in the technological development were made clear as high heat insulating performance, optimization of the shield structure, measures for thermal stress, anti-seismic measures, and sealing mechanism at joints, in addition to the vacuum heat insulating piping technology that has been built to date. The liquid hydrogen valve is subjected to a technological problem of the very low temperature and combustion performances of liquid hydrogen, which requires further researches. With respect to the instrumentation facilities, as a result of discussing the liquid level meter system and the flow rate meter system, it was found that there is no almighty method, whereas selection of the method should be as required in particular situation.

    With an intention to establish a technology required to build a hydrogen storage tank with a storage capacity of 50,000 m{sup 3} as the target shown in the basic plan for WE-NET, the current fiscal year has performed the technical literature surveys to identify the existing technologies. In the survey on the similar large storage system, a liquefied natural gas (LNG) was taken up, and the survey on the LNG bases in Japan was carried out. With regard to the existing liquefied hydrogen storage system, surveys were performed on the test site for developing the liquefied hydrogen/liquefied oxygen engines, the rocket launch sites, and liquefied hydrogen manufacturing plant. In relation with peripheral technologies for the underground storage tank being an excellent anti-seismic form, the LNG underground storage facilities were surveyed. Regarding the rock mass storage tank, surveys were carried out on the LPG rock mass storage having been used practically, and the LNG rock mass storage that is in the demonstration phase. In the research on storage facilities, surveys were executed on the forms and heat insulation structures of the similar large low-temperature storage tanks, the use record of the existing liquefied hydrogen storage tanks, heat insulating materials, and heat insulating structures.

    A system is being developed for adjusting incident solar energy in accordance with objectives by using, as a window material, glass whose light transmittance is variable by the electrochromic color and bleach reaction. The target is a module which, having an area of 60x40 cm or larger, is capable of installation for a structural opening of a building, which has a practical service life (ten years outdoors), and which is provided with the range of visible transmittance of 50% or more with capability of continuous light adjustment. In fiscal 1994, a basic parameter was set for the production process of a large module, with the experimental production/evaluation conducted, and with an outlook formed for achieving the target. The device is basically composed of glass, transparent electrically conductive film, counter electrode, electrolyte, principal electrochromic film electrode, transparent conductive film, transparent resin film for sealing, and glass, with the total thickness 4 mm or above. The transparent conductive film in use is tin-based, the counter electrode is NiOx based in oxidation color-erasing type, the electrolyte is Sb{sub 2}O{sub 5}, and the principal electrode is WO{sub 3} based in reduction color-developing type.

    Actualities of exhaust heat and demand for heat in the area are investigated on the result of which a wide-area energy utilization network system will be built. In fiscal 1998, further questionnaires are distributed in addition to last fiscal year's, and door-to-door visits are made on leading factories representing 10 types of industries. The result of data analysis places the nationwide total of exhaust heat at 320,000 Tcal/year including heat generated by electric power generation. When it is so defined that usable heat be above 150 degrees C for exhaust gas, above 40 degrees C for hot water, and above 200 degrees for solids, the total will be reduced to 230,000 Tcal/year. Cleaning plants (plants that treat refuse or sewage) as the sources of exhaust heat besides the factories are investigated for the amount of heat they discharge, and then it is found that the amount of heat they discharge is the fourth largest following electric power plants, iron and steel mills, and chemical plants. It is also found that most of their exhaust heat is of good quality because it is latent in steam or hot water. It is acknowledged, partly because many of such plants are situated relatively near to the urban district, that their role is important when studies are made on the utilization of exhaust heat.

    Power generated by solar cells complying with NEDO (New Energy and Industrial Technology Development Organization) specifications is stored in a storage battery or is converted into AC power in a DC-AC converter for interconnection with a commercial power system, and then supplied to loads in schoolhouses. The system operates independently when the commercial power system is out. Basic plans and primary specifications had been determined, basic modules experimentally built, tested, and part of their details designed, all these up to fiscal 1980. In fiscal 1981, system design details are drawn, housetops are examined for installation, and problems that may entail installation are checked. A system data accumulation unit comes into operation for data collection. A system simulator is developed and constructed and the solar cell is checked for performance. Model arrays are built and subjected to a combination tests, when the effect of shade is also investigated. A charge control unit, high-efficiency GTO (gate turned-off) thyristor DC-AC converter, and a protection circuit in preparation for interconnection are developed, and experimentally constructed. In fiscal 1982, 20kW solar cells will be installed and schoolhouse systems will come into service operation. (NEDO)

    As a research on systematizing ECO and ENERGY cities, surveys and analyses were performed on the actual state of introducing district heat supply systems utilizing difference waste heats including factory waste heat. Waste heat from electric power generation is utilized for district heat supply in Japan at 122 points or about 20% of the district heat supply points in operation as of March 1998. The number is in the increasing trend in recent years, and the future potential of its introduction can be said high as the history thereof is still short. Its introduction form is accounted mostly for by building cogeneration or plant cogeneration. Back-up facilities for the case when waste heat supply stops because of regular facility checks are provided by the heat supply business operators, which impede the economy of the system. In the U.S., the Public Utility Regulatory Policy act motivated installation of cogeneration and off-peak power generation systems for district heat supply. Technical maps (for waste heat sources and different waste heat utilization systems) were prepared based on the surveys to discuss the future measures. (NEDO)

    Described herein are the results of the FY1994 research program for chemical refrigeration and cold storage system using solar heat. The study on refrigeration materials are aimed at development of new hydrogen-occluding alloys which show good hydrogenation equilibrium characteristics and reactivity at temperature required for stand-alone refrigeration systems aided by solar heat, and still new hydrogen-occluding alloys operable at refrigeration temperature for lower-temperature systems. For the refrigeration materials capable of producing low-temperature heat of -10{degree}C at a regeneration temperature of 140{degree}C produced by solar heat, a La-Ni-Mn-Al alloy is selected for high-temperature use and a La-Y-Ni-Mn alloy for low-temperature use. The study on technology for refrigeration modules develops high-efficiency heat exchangers for refrigeration and regeneration, compatible with the hydrogen-occluding alloys. It also develops air-and water-cooling techniques for hydrogen-occluding alloys, where air is used as the heat source. The test apparatus is designed, installed and operated, to attain a low temperature of -10{degree}C or lower with a heat source of 140{degree}C and air heat source of 28{degree}C. 7 figs.

    This technology development aims at developing the design technology of the array type wind power system and the control technology to efficiently operate the system. As a result, the wind turbine produced by Micon was selected. The rated power is 100kW, and the number of the wind turbine is three. The three-phase short-circuit capacity at the generating end of the wind power generation facilities is 26,25 MVA, which can fully be broken. A simulation of voltage variation/frequency variation was made to grasp various phenomena of the output of the wind power system influencing the power source system and power distribution system. As a result, it was confirmed that it is possible to operate the system safely without lowering the quality of power. As to the overall monitor/control system which controls wind turbines, five wind turbines as many as possible are grid-interconnected and the number of wind turbine is to be controlled by a ratio of the total demand power to the gross generating output of wind power in the Miyako system, for the purpose of increasing the rate of equipment utilization of the wind power system also at the time of the lowest load of the Miyako system. In the operation of two-system interconnection, the gross power generating amount was 1,321,250 kWh, which increased 9.7% over the results in FY 1993. (NEDO)

    This paper describes the achievements in fiscal 2000 from the WE-NET Phase II for Task-5, the development of a hydrogen fueled automobile system. For a fast filling method using a hydrogen absorbing alloy as the fuel tank, a rare earth system, the Laves system, and a body-centered cubic system were selected to discuss filling time when the plate-fin system tank and the divided system tank are used. Either system was found capable of filling 80% of the effective hydrogen absorbing amount within 10 minutes, having achieved the target. Guidelines were obtained for the design aiding method by using the cooling water flow rates, temperatures, and simulations. In the safety assessment, even the spontaneously combusting alloy of Category 1 in the Fire Fighting Law did not cause ignition even if the tank was damaged and the alloy was discharged in the dropping/falling weight tests. It was inferred that the ignition temperature is not reached because of the self-cooling made when hydrogen is discharged from the alloy. In the fire resistance test, the tank temperature was found not to rise as long as hydrogen is discharged from the alloy. Since the temperature rise and damage could occur if the discharge has been finished completely, discussions are required on materials and the soluble plug. Deformation may occur in the initial stage of the hydrogen absorbing and discharging cycles, but it would not occur after 5,000 cycles. (NEDO)

    Concerning the above, it is discussed whether such a system is feasible in Japan. A zinc/air cell system requires some special plants for zinc regeneration, etc. It is necessary to build a zinc refining plant and to install dozens of electrode replacing facilities in an area dozens of kilometers in diameter with the plant at the center. For such a system to be functional, there have to be several tens of thousands of automobile users in a limited area. In Japan, so large a number will not be found anywhere even if the appeal is directed to those in the postal service and electric utilities. There will be no economic success in Japan, different from in Germany. As for the economic comparison between a zinc/air cell system and natural gas system, the two will be equivalent to each other as far as the use of the quick filling stations for the natural gas automobiles remains as it is. When the number in consideration is so large as several tens of thousands, however, the natural gas system will turn out to be economically superior to the zinc/air cell system. 19 figs., 29 tabs.

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

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

    This paper describes the achievements in developing a high-calorie gas manufacturing technology for coal gasification in the Sunshine Project in fiscal 1981. Pulverized coal and heavy oil are heated and stirred to make it a slurry, which is forced into a fluidized bed gasification furnace together with spraying steam, and pyrolyzed by using a unique slurry feeding system (a hydrohoist). Carbon-like material as a by-product (char) is partially oxidized (burned) by steam and oxygen at the lower part of the gasification furnace. The material is gasified in the furnace, where the generated heat is sent to the pyrolysis zone in the upper part by the gas and fluidized bed media particles (char), and utilized as a heat source for the slurry pyrolysis. The produced gas is cooled by an indirect heat exchanger of the fluidized bed system and a scrubber to separate tar, dust and unreacted steam. Part of the sensible heat is recovered as steam. Thus, high-calorie gas of 6,000 kcal/Nm{sup 3} can be obtained, which is rich in methane, CO and hydrogen. Fiscal 1981 has performed a continuous test by using an internal heat type low-pressure gasification equipment to evaluate its compatibility to the diversification of materials. (NEDO)

    This project studies the testing/evaluation methods for spreading fuel cells for automobiles. Described herein are the FY 2000 results. The problems involved in evaluation of the single cell units are classified into those involved in the cell construction and methods of evaluating the operation performances of the single cell units. These problems are analyzed mainly by literature survey. The mode simulation tests will be greatly simplified, if the system can be tested on the bench without being actually boarded on the vehicle. Therefore, this project is aimed at development of a comprehensive mode simulator which can be automatically operated corresponding to the running modes of various countries, to test the performance of FCEV and to examine the effects of each component independently on the vehicle performance. The factors required to reproduce the actual driving states of an FCEV on the bench are analyzed, and the conceptual designs are drawn for the controlling algorithms. It is necessary to standardize the stack and reformer testing methods, in order to evaluate the fuel cell system components. For these objects, the prototype units are constructed to evaluate 10kW direct hydrogen type stacks and 5kW methanol reformers. The units are also constructed to evaluate the high-pressure (1MPa) reformer reactors and hydrogen separation membrane systems. (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)

    A numerical model was prepared to express fields and size of hydrogen energy introduction in Japan's energy systems in the future. Dividing Japan into 13 weather sections, one to two energy bases (import and secondary production bases in coastal areas) were assumed on each section. Secondary energies produced in these energy bases are transported to intermediate bases, from which the energies are distributed into cities and consumed. For the purpose of simplification, final consumption departments are hypothesized to exist in these intermediate bases. Parameters that characterize the flows on networks in the processes of supply, distribution, production, storage, transportation and utilization are divided largely into energy efficiency and cost of the processes. The amount of energy demand in each final consumption department was defined as an amount to maximize the expected effects as a result of having satisfied the demand. The result of trial calculations revealed that, as long as the hydrogen to be introduced is limited to hydrogen produced via electrolysis using thermally generated power, the hydrogen introduction into the future energy systems is difficult in terms of economic performance.

    As an energy conservation promotion measure, a project is under development for introducing and subsidizing high-efficiency energy systems and for letting their effect known publicly and widely. The number of proposed energy systems has increased greatly and technical divisions to follow in classifying them have become vague, from which problems are now arising over the execution of follow-up checks and the maintenance of fair treatment. In the effort to solve this problem, 376 propositions are analyzed and classified, a technical classification method is proposed, and an instruction manual on the method is compiled. The classification involves (1) proposed classification, (2) variation, (3) energy reduction rate, and (4) tentatively calculated cost. Item (1) deals with the basic classification (air-conditioning, ventilation, and hot water supply, and, to be considered in combination with them, options which are cooking, illumination, and others) and, item (2) covers eight items such as new/old construction, structure, and structural frame. In Chapter 1 of the report, the 376 propositions are put in order according to common classification items and an original classification table is prepared. In Chapter 2, the goals are clarified and the classification principles are defined. In Chapter 3, the classification is checked for its validity and some realistic ways of grouping are described. In Chapter 4, a classification implementation flow chart is shown. (NEDO)

    This paper describes development of hydrogen gas turbines from among the comprehensive discussions on hydrogen utilizing subsystems. Hydrogen and oxygen gas turbine cycle has varying optimal conditions of plant efficiency depending on fuel patterns. The regenerative cycle may have the turbine inlet temperature at about 1,000 degrees C. The inlet pressure would be ten and odds atmospheric pressure. It is better to keep the inlet temperature higher in order to obtain high specific power. Reduction of power generation cost in using this plant requires that construction cost be decreased, and the specific power be increased if the plant efficiency (in other words, running cost) is assumed constant. Further development is required on technologies to use higher temperatures and pressures. For that purpose, discussions should be given on material development, structural design, and inspection. Hydrogen gas turbines, which present low pollution depending on combustion methods, have great significance for such social problem as environmental contamination. In terms of economy, since hydrogen gas turbines depend on efficiency and fuel unit cost, the evaluation thereon may vary depending on how well the regenerative gas turbines have been established, in addition to future change in hydrogen price and the technologies to use higher temperatures and pressures.

    The quantum yield and conversion efficiency are measured during photosensitized water decomposition at an n-type TiO{sub 2} semiconductor electrode built from a rutile type single crystal, and the role of the TiO{sub 2} electrode is clearly defined. A method is tested of acquiring a photoactive TiO{sub 2} semiconductor as an oxide coating and an oxide coating electrode is fabricated, and its characteristics are determined and then compared with the above-said measurements. A WO{sub 3} semiconductor is manufactured, and its characteristics are compared with the above-said measurements. The mechanism of photosensitized decomposition at a semiconductor electrode is examined, and guidelines are established to follow for improvement on efficiency in semiconductor electrode-aided hydrogen production. Dark and light reactions are caused to occur by adding methyl viologen, potassium ferrocyanide, and potassium ferricyanide, and the photochemical reaction characteristics are clearly defined. Oxygen is generated by use of chloroplast. Use of an acrylamide membrane and an osmotic membrane enables a continuous 48-hour test.

    The whole amount of hydrogen consumption for chemical industries all over the world is estimated to be 249.7 billion Nm{sup 3} in 1974, while 367.2 billion Nm{sup 3} in 1980 roughly under a bold assumption, based on 3 current big consumption fields of ammonia production, methanol production and petroleum refining, and some promising fields in the future such as reduced iron and synthetic protein. Consumption ratios for every field are probably 54.9% in ammonia production, 30% in petroleum refining, 9.5% in methanol production and 5.6% in others in 1974, and nearly similar in 1980. However, although there are various troubles, if a large amount of methanol is used as fuel in the future, and its production plan is promoted to satisfy the demand of methanol fuel, hydrogen consumption for methanol production will increase drastically. In the future, if the production process of hydrogen as secondary fuel is established, such hydrogen also will be used for various chemical industries naturally. Research was thus made on use of oxygen as byproduct inevitably. (NEDO)

    This is aimed at making an investigational study on the hydrogen production from water by means of quinone compounds. The paper studied a preparation method in case of using n-TiO2 photosemiconductor and p-GaAs and Gap photosemiconductor to photoelectrode as catalysts of this reaction. The reaction from p-benzoquinone to p-hydroquinone by reaction with H2O were studied in terms of photochemical reaction, and light reaction/dark reaction of photosemiconductor electrode. As a result, it was found out that this reaction easily advances by the photochemical reaction by solar light, and also that it advances by the counter electrode Pt electrode reaction in the water electrolysis of n-TiO2 photosemiconductor electrode. The H2 production reaction from p-hydrogquinone was studied in terms of the photochemical reaction, photosemiconductor electrode reaction, and effects of the catalysis of electron transport of metal salts, methylviologen, etc. As a result, in the n-TiO2 photosemiconductor electrode reaction, H2 formation was not as great as it can be confirmed. However, it was found that p-hydroquinone can produce H2 under the existence of methylviologen or Fe salts. (NEDO)

    The paper made an investigational study of the data of a wide range which seems to be related to the use of hydrogen as automobile use fuel. The advantage is that the exhaust can almost be non-pollutant. The engine performance can be on the same level as that of the present gasoline engine or can be improved. The reasons are that the compression rate is heightened and that automobile can be driven at lean mixture rate. As to weak points, the volume and weight increase when it is loaded on vehicle. The cost of hydrogen is higher than that of petroleum. The problems to be quickly solved are as follows. Improvement of the combustion method: a wide range of development not only the electric ignition method, but the diesel method, and the basic study for it. It is necessary to establish the basis for a method to connect the storage method and engine. It is also necessary to comprehensively review rules related to safety. For the future, the conversion to artificial fuel is indispensable, and hydrogen has the most characteristics as energy medium. The problem is much larger sizes of fuel tank and pump, but there will be a possibility of producing a new technology together with the hydrogen production technology. The fundamental research should be promoted without any hesitation. (translated by NEDO)

    With an objective to utilize hydrogen fuel in aircraft engines, a conceptual design survey was carried out on medium size transport aircraft. Large size long-distance aircraft and SST loaded with a great amount of fuel have the jet fuel (JP) increase take-off weight, affecting largely the selection of wing area and engine thrust. If the hydrogen fuel can be liquefied, large reduction can be achieved and the economic effect can be increased. However, for short-distance transport aircraft, the fuel weight ratio is small, where no large advantage is anticipated even if hydrogen is liquefied. Nevertheless, considering oil depletion in the future, a conceptual design was performed on the YX2688 short-medium distance aircraft being discussed of development. Even the short-medium distance aircraft that can be developed and commercialized as civilian use aircraft has a number of common points with large aircraft development, such as hydrogen fuel using technologies and safety. Although the advantage of using liquefied hydrogen as fuel may of course be smaller in the short-medium distance aircraft than in larger aircraft, the trend of using hydrogen fuel is historical necessity, whose development plans should be moved forward.

    This paper describes comprehensive discussion on hydrogen utilizing subsystems. Hydrogen combustion is characterized by how low the ignition energy is, and how fast the flame propagates. In addition, flame stability is high also in diffusion combustion. However, the diffusion combustion produces a great amount of NOx, the amount varying depending on the degree of air pre-mixture. Since it causes reverse ignition very easily in the pre-mixture degree corresponding to low NOx zone, development of a burner with drastically new mechanism is demanded. In hydrogen fuel cells, the ratio of hydrogen fuel cost accounting for in the power generation cost is very high. As an automobile fuel, very much leaner combustion is possible than in conventional internal combustion engines, and ignition energy is small. However, such abnormal combustion as reverse ignition and early ignition may occur, and their prevention is an important assignment. Issues in aircraft engines are verification of safety, and cost of liquefied hydrogen. Steam turbines have reached their limit already, but gas turbines are expected of exciting efficiency improvement. This paper describes prospects on chemical utilization of hydrogen in the existing fields and new fields. (NEDO)

    Surveys and studies were performed on chemical utilization of hydrogen regarding its status of development and utilization inside and outside the country, as well as its future prospect. This paper describes chemical utilization of hydrogen in ammonia, methanol, petroleum refining and other industries as the existing fields. It also describes chemical utilization of oxygen in iron and steel, chemical and other industries. It describes methanol as a pollution-free auxiliary fuel for electric power plants as a new type of hydrogen application. Acetic acid made by using the Monsanto method which carbonylate methanol is drawing attention in terms of economy, and is in the phase of discussing commercialization. Synthesizing ethylene glycol from carbon monoxide and hydrogen may be conceived economically. Methanol for synthesized protein depends on the possibility of future development. In the iron and steel industry, electric furnace steel makers are planning production of reduced iron, where the direct reduction process using hydrogen is considered as a complementary process, including countermeasures for scrap iron. This paper estimates hydrogen amount as a raw material for ammonia to remove NOx by using the ammonia reduction process. It also describes possibility of other types of utilization. (NEDO)

    This paper reports on the present situation of the chemical use of hydrogen and oxygen, and the short-term, medium-term, and long-term forecast. The main usage of hydrogen is ammonia synthesis, petroleum refining, and methanol synthesis. In the usage of these three, there are factors of structural changes now and in future, and it is extremely difficult to predict the amount in a short term up to around 1980. In a medium term prediction, from the result of predicting the demand of ammonia, methanol and hydrodesulfurization, the total 1985 hydrogen demand is estimated at approximately 60 billion Nm{sup 3}, and approximately 67 billion Nm{sup 3} as the gross hydrogen demand. Further, judging from that synthetic protein, fuel use methanol, and reduced iron are estimated to reach a certain production size in and after 1985, new demand for hydrogen is expected to be approximately 100 billion Nm{sup 3} mostly including fuel use methanol. In a long term prediction, it is extremely hard to predict the demand because of various factors existing in Japan and abroad. As predicted in a medium term, the amount of chemical use of hydrogen is expected to increase more and more, even if calculating it only in the field of ammonia synthesis, petroleum refining, and methanol synthesis.

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

    An airborne gamma-ray survey was carried out to investigate the active fault system in the central structure line in the peripheral area of the city of Wakayama. At the same time, with an objective to enhance applicability of the airborne gamma-ray survey to active fault investigation, fundamental data were acquired and discussed. The measurement data were processed according to the standard method specified by IAEA. An ID-FFT filter and a nonlinear filter were employed to extract anomalous gamma-ray intensity values. The gamma-ray intensity distribution chart shows a noticeable positive anomalous area extending from the central part of the western edge to the north-east direction. This area agrees nearly well with the Negoro fault, but its peak portion is positioned slightly more to south than the position of the Negoro fault shown in existing data. The Sakuraike fault and the vicinity of the central structure line also show positive anomaly as a whole, particularly remarkably in the vicinity of their converging portion. However, differing from the vicinity of the Negoro fault, the areas are not extracted as an anomalous area which has directionality and extends in a line form. One of the factors for this would be that it is a fault in unsolidified deposits with low opening trend, differing from the one in solidified rocks. 1 fig., 3 tabs.

    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.

    This report summarizes the fiscal 1999 research result on the safety of hydrogen absorbing alloy tanks for hydrogen vehicle systems and the measuring method of a fuel consumption rate of hydrogen fuel cell powered vehicles. In the impact rupture test of (mini-scale) hydrogen absorbing alloy tanks, the impact 3-point bending test result by drop weight showed no ignition caused by impact and friction energy acting on hydrogen released by rupture of tanks, and the necessity for taking spontaneous ignition of alloys due to fuel leakage into account. The experiment result on deformation and rupture of alloy tanks caused by expansion and contraction of crystal lattices due to hydrogen absorption and desorption showed relatively large deformation due to grain fining only within earlier 10 cycles, and no cracks nor other defects even after 1000 cycles. In the measurement of a fuel consumption rate of hydrogen fuel cell powered vehicles, the study result on flow rate measurement method, full tank method, electric current method, hydrogen balance method and oxygen balance method showed that the electric current method is most simple, accurate and practical.

    This paper describes the achievements in fiscal 1998 on developing ITS technology using clean energy driven automobiles. Development is intended on an efficient management and control method for EV car rentals in tourist resort areas using the ITS technology from the viewpoints of reducing road traffic load and global environment problems. The development items include a control center system, a system to control battery charging status at the center, a battery charging determination algorithm, and a car navigation and bi-directional communications mounting system. The system development has been completed nearly completely, having attained relatively high user satisfaction. However, because of the experimental rented cars having long mileage, there were few chances of verifying the charge determination algorithm and the functions of the ITS. Investigations were carried out on technological trends in overseas countries on EV and ITS, and on commuter car introduction projects. Structuring the hardware for a commuter EV system is not too difficult if the presently available EV and ITS technologies are used. However, in advancing commercialization, there are such assignments as establishment of software, operation patterns, and interfaces that enhance user convenience and profitability. (NEDO)

    This paper reports the achievements in fiscal 2000 in the development for practical application of a new power generation technology for the human cooperative and coexisting (humanoid) robot system. Carrying out the development smoothly and efficiently requires accumulation of the system operational know-how, as well as the periodical check and maintenance to maintain the functions and performances of the robot platform having been developed in the previous fiscal year. Checks were given on the robot platform hardware, and no anomalies were verified in all operation. For the remote operation platform, normal operations were identified in the visual and audio information presenting and communication systems, including such components as the PCI, noise removing card, three-dimensional microphone, and SGI320. Operations were confirmed on the movement and operation sensing and presenting system, whereas no change has been found in the operation for the period of one year, and sufficient performance was maintained. For the virtual robot platform, the operation was made open to public on the basic operation library network interface. No operational defects, damages, wear, and electrical failures were found in the master hand for the remote control by hands, force sense presentation, finger and wrist position detection, and contact angle presentation.

    The paper described the result of the fiscal 1996 development relating to hydrogen combustion turbines, as one of the hydrogen utilization technologies, which have excellent environmentality and are expected of remarkably high efficiency. In the film cooling system of first-stage moving/stationary blades, the smaller the pitch of film pore is, the higher the mean cooling efficiency becomes, indicating 0.7 at maximum. As compared with the conventional shower head type, the metal temperature can be reduced 30-40degC. In the recovery type inner (convection) cooling system, by reducing the blade number, the consumption amount of coolant can be reduced 6% in stationary blade and 13% in moving blade, as compared with the result of the preceding year. In the element test of the hybrid cooling system, film cooling efficiency was actually measured by the porous module test equipment, and the result well agreed with the calculation result. In the water cooling system, studied were water (stationary blade) and vapor (moving blade) of the closed cooling structure for realization of a cycle efficiency of 60%. In rotor/disk cooling, analyses were made of seal characteristic grasp tests and characteristics of the rotor. The effect of deflection in the mainstream was small. Besides, proper value of the seal overlapping amount could be obtained. 6 refs., 368 figs., 55 tabs.

    This paper describes the achievements in fiscal 2000 from the WE-NET Phase II for research and development Task-6. The objective is to verify performance and reliability, by means of field tests, of a power generation plant using fuel cells of pure hydrogen fueled solid polymer type with power transmission terminal efficiency of 45% and output of 30 kW. The fuel cells were developed by using the cathode humidification process as a humidification method suitable for operation at high utilization rates. With a three-cell stack made by using this humidification process (having an effective area of 289 cm{sup 2}), verification was made on the current density of 0.2A/cm{sup 2}, the characteristics of 0.75V or higher, and the uniform voltage distribution performance being the immediate targets. In order to mitigate the hydrogen utilization in the fuel cells, discussions were given on the serial flow system that divides the laminated cells into two blocks. Thus, operation was found possible with the utilization rate in each block reduced to about 80% by selecting an adequate division rate even if the hydrogen utilization rate is 96% in the entire stack. Stable operation has been performed in the 5-kW class power generation test using the cathode interior humidifying system. Specifications for 30-kW class power plant, system configuration, safety, and material balance were discussed. The basic design was made on the hydrogen gas humidity adjusting system. (NEDO)

    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)

    In reference to 20 to 40 cpm letter size monochrome digital copiers, R and D was conducted for the purpose of developing an energy-saving fixing system by the combination of a thin-layer thermal-roller fixing unit and a low-fixing-temperature polymerized toner, with the fiscal 2000 results compiled. In the development of the thin-layer thermal-roller fixing unit, a fixing system suitable for toner characteristics was completed, through the optimization of a temperature-stabilizing cooling fan and by a mechanism for detecting anomalous high temperature at the time of a runaway heater, for example. In the research of the low-fixing-temperature polymerized toner, efforts were made toward improving somewhat weak electrostatic chargeability, which was a conventional problem in toner characteristics, and enhancing the thermal/mechanical durability of the toner. In the method of improving electrostatic chargeability, a new process was developed capable of effectively functioning additives in a toner, attaining a level practically free from problems. In the heat resisting characteristic, its enhancement was achieved by developing a method that checks no fused fixing performance at the time of heating for fixing and that imparts a new heat resistivity to a latex surface layer less susceptible to heat inside a copier.

    Storage batteries used in household photovoltaic systems must be free of electrolyte leakage and maintenance, and be readily installable in residential houses. Lead-acid batteries that can meet these requirements and have been put into practical use may include the sealed storage batteries. However, these batteries currently in use have drawbacks in life performance and price. Therefore, development is under way on lead-acid batteries for household photovoltaic systems by improving said sealed lead-acid batteries. The targeted batteries should have as long life as passing 3,000 cycles under a condition of 0.1 to 1 CA discharge (at depth of discharge of 50%), energy density of more than 70 Wh per liter, and cost of 12 yen or lower per watt-hour. A prototype battery as the final candidate was fabricated, that uses silica powder as the electrolyte retainer (silica powder filled between plates, and into clearance between plate groups), pasted plates made of expanded metal grids for positive plates, and micro conductive network plates with increased addition amount of carbon to micro active material (PbO{sub 2}) as negative plates. Life performance testes thereon are being performed. This lead-acid battery is estimated to be capable of satisfying the intended performance based on the result of discussions having been made so far. (NEDO)

    Research and development has been performed on a system technology for the human cooperating and coexisting type robot that can perform various types of works substituting human hands. This paper summarizes the achievements in fiscal 1999. In developing a high-function hand, development and fabrication were executed on a device to teach four finger holding actions that correspond to the enhancement in action stability and control responsiveness of the four finger hand and to positions and attitudes of objects. In fabricating the robot platforms, single platform tests and remotely controlled platform connection tests were performed, which demonstrated the functions as an integrated system. In developing libraries for topography adaptive three-dimensional basic walking actions, development was carried out on libraries that correspond to menus for direct advance on a flat land, slewing, and walking on staircases and irregular land. It was found that control closer to that for actually usable robot is possible by considering time delay in articulate control when simulation was performed using the testing robot body. In the study and survey of robot proliferation, development plans were presented that take into consideration the social influence, technological factors, and cost need adaptability. (NEDO)

    Feasibility study was conducted on the technology for practical application of a several kW class fuel cell for the people's livelihood, particularly, for residential use. The study was made in six areas consisting of study on the present state of technology, conceptual design of a small fuel cell, survey on a promising market, basic concept of cell for residential use, feasibility study on application and on introduction. There is no record of development of the several kW class; while the fuel cell excels in the efficiency of energy utilization and the environmental conservation, its performance greatly deteriorates by start and stop under the present technology. Accordingly, it is a prerequisite that the equipment is for an electric heat combined type and for system interconnection. Also, while it is proper that the cell is phosphate type and that the fuel is natural gas, an innovation is necessary in the technology for reforming the cell and the fuel. The conceptual design revealed the possibility of a power generation system having a generating efficiency of 32%, exhaust heat recovery rate of 30%, and dimension of 75x65x150 cm. On the basis of a feasibility study on the application to the combination of a house and a beauty parlor, an advantage was recognized in the fuel unit cost of 5 yen/meal and the equipment cost of 200-250 thousand yen/kW, with demand estimated for 2.5 million installations nationwide including 950 thousand in natural gas supply districts.

    Research and development have been carried out on a high-level water purifying system using ozone and activated charcoals to supply drinking water free of carcinogenic matters and odors. This system comprises a system to utilize ozone by using silent discharge and oxygen enriching device, and a living organism/activated charcoal treatment system. The latter system utilizes living organisms deposited on activated charcoal surfaces to remove polluting substances including ammonia. The treatment experimenting equipment comprises an ozone generating system, an ozone treating column, an activated charcoal treating column, an ozone/activated charcoal control device, and a water amount and quality measuring system. An experiment was carried out using an experimental plant with a capacity of 20 m[sup 3]/day on water taken from the sedimentation process at an actual water purifying plant. As a result, trihalomethane formation potential was removed at about 40% in the ozone treatment, and at 70% in the whole treatment combining the ozone and living organism/activated charcoal treatments. For parameterization of palatability of water, a method is being studied that utilizes nuclear magnetic resonance to investigate degrees of water cluster. The method is regarded promising. 1 ref., 4 figs.

    Sludge generating in a sewage treatment plant is disposed through the processes such as concentration, dehydration, and incineration in sludge disposal facilities. In recent years, there has been a trend that this sludge increases in volume as well as worsens in the concentration. A case is predictable where the sludge load to the dehydrating process is so large that the sludge can no longer be processed in sufficient quantity. In the meantime, if sludge is ozone-treated, viscous substance on the surface of sludge particles can be separated with a comparatively small amount of ozone, with sludge concentration enhanced. At Meidensha, an experimental plant was set up for the ozone treatment of sludge in a sludge intensive treatment plant of a metropolis, with a verification experiment carried out for a sludge concentration improving system by ozone. As a result of comparison of the treatment performance between an assessment system for performing ozone treatment and a reference system for not performing, the average value of the sludge concentration of a gravity concentration tank was 1.9% of the reference system against 1.7% of the assessment system in a continuous treatment experiment in the summer, while the solid collection ratio was 65.8% of the reference system against 95.5% of the assessment system, enabling a superior improving effect to be obtained.

    This paper reports the achievements on research of pyroelectric power generation systems in fiscal 1998. In the research, a small continuous pyroelectric conversion equipment was fabricated and experimented. The experiment using an aluminum foil electrode revealed that the foil melts during discharge opening holes, thus making it impossible to increase net conversion efficiency. The net conversion efficiency was derived in an experiment using foil evaporated with indium instead of the aluminum foil. Indium has inferior electric conductivity to aluminum, but is melting point is as low as 145.6 degrees C. Therefore, if a pyroelectric film had electric fatigue due to use over an extended period of time, indium may be melted to make recovering and reusing pyroelectric copolymer possible. Thus, the indium electrode was found suitable for pyroelectric conversion. Analysis of the experimental data indicated that the final possible net output can be 7.6 W/m{sup 2} if each operation variable considered possible in the future is superimposed on the pyroelectric film. This survey revealed that low-temperature waste heat can be converted to high voltage continually by using the pyroelectric conversion equipment at CANMET Energy Technology Centre. (NEDO)

    This research and development project is aimed at modification and improvement of the stacking technologies, to improve service life and performance of the molten carbonate fuel cell power generation system and reduce its cost. For the cross-flow type stack, optimization of the anode firing conditions leads to controlled reduction of the fine pores, and incorporation of the cathode with MgO successfully leads to controlled elution of NiO and Ni short-cut. For the separator, the service life is extended by treatment of the material with Al and controlling its rigidity. The cell life prediction method is improved to enhance its accuracy. The cell life of -4.3mV/1,000h is achieved by these technologies. For the parallel-flow type stack, the electrodes are improved to achieve the cell life of -1.4mV/1,000h, the technologies for producing the separator for a 1m{sup 2} class unit are developed, and the basic structures of a large-capacity stack are designed. For the internal reforming type, a 200kW class reforming stack is constructed, and operated for 5,259 hours. The causes for electrolyte loss are analyzed by developing the relationships between operating temperature and electrolyte loss, electrolyte mass and sustainability of the cell characteristics, and steam partial pressure over the cathode and electrolyte loss, and also by testing the Ni short-cut.

    Survey was made of the case of applying the low grade coal reformation technology to commercial plants in Indonesia. In the survey, supposing the UBC process as reformation technology and 5,000 t/d as size of the commercial plant, studies were made of companies to be applied, schemes on the usable fund raising/governmental supporting policy, potential diffusion/effects of diffusion, facilities which can be domestically manufactured/subjects in promoting the domestic manufacture, economic F/S, etc. Different from the first generation coal companies, the second generation coal companies own low grade coal for the most part of the coal resource. Therefore, the companies are very much interested in the reformation technology. In the financial plan, the equipment cost of a commercial plant of this size was estimated at approximately 10 billion yen. This is a large initial investment for coal companies in Indonesia. So, it is necessary to consider a system of joint venture with Japanese users, etc. As to the study of the economical efficiency, the trial calculation indicated that the reformation cost was 7.35 US$/product ton and the price of reformed coal briquette product was 19.85 US$/product ton. In this case, ROI (return on investment) of 8.40%/year was expected. (NEDO)

    This paper explains the results of development of a hydrohoist system in a direct hydro-liquefaction plant under the Sunshine Project in fiscal 1981. Coal liquefaction deals with three phases of gas, liquid and solid at high pressures of 100-300 kg/cm{sup 2}. Slurry consisting of coal, catalyst and solvent is once fed into a supply chamber by a low pressure slurry pump. A high pressure slurry formed in a liquefaction reactor, after the separation of gaseous object, is boosted by a booster pump and force-fitted into the supply chamber from the above, discharging the slurry in the chamber to the high pressure reactor side. Since the high pressure product is used as the driving liquid, a force-feeding motive force can be greatly curtailed. It is a motive force recovery type hydrohoist. The product slurry in the supply chamber is discharged from a valve in the upper part; with the inner pressure going down quickly, the discharge valve wears very little. The basic experimental equipment was manufactured in fiscal 1980, with a test research conducted using the improved main equipment in fiscal 1981, and with the conceptual design of the hydrohoist also implemented on the assumption that it was applied to a pilot plant.

One hundred and forty six general waste power generation facilities of 558,000kW are in operation in 1995, and among them 89 facilities supplies 1,080 GWh to power companies. 50 industrial waste power facilities of 247,000kW are in operation. 20,000 solar systems and 180,000 hot water heaters are in operation in 1995. Commercial geothermal power generation facilities of 490,000kW and private ones of 36,000kW are in operation. Introduction of expensive clean energy vehicles is making very slow progress. The pilot study on bituminous coal liquefaction is in promotion mainly by NEDO. The experiment of entrained bed coal gasification in Nakoso was successfully completed, and development of a commercial plant is to be expected. Power rates of 10 power companies were reduced in 1996, and unit purchase prices of surplus power of photovoltaic and wind power generation were also revised. The new menu and unit purchase price were announced in 1996 for surplus power of waste power generation and fuel cell. 67 figs., 284 tabs.

    Described herein are the results of examination and promotion of measures to obtain international understanding and cooperation, and examination and development of measures to promote international exchange of technical information, conducted in the FY 1998 continuously from the previous year, with the object to realize the International Clean Energy Network Using Hydrogen Conversion (WE-NET) project. In the FY 1998, the English version of the 1997 annual summary report was distributed to a total of about 150 overseas organizations. The WE-NET project activities were presented to the 12th World Hydrogen Energy Conference, International Joint Power Generation Conference held in 1998 by American Society of Mechanical Engineers, and 2nd International Symposium on Advanced Energy Conversion Systems and Related Technologies. For the examination and development of measures to promote international exchange of technical information, the contracting party of Japan for the Hydrogen Implementation Agreement with IEA has been shifted from the government of Japan to NEDO. NEDO has been representing Japan for various workshops on the tasks. The hydrogen projects conducted by Germany and USA were also surveyed. The WE-NET project homepage was opened in June, 1998.

    Search and assessment were carried out on innovative and leading technologies which are outside the development objects at the present, but are promising for the future. This paper describes the achievements in fiscal 2000. In the hydrogen manufacturing method using natural gas as the raw material, but not generating carbon dioxide, a method using plasma has the hydrogen conversion rate of more than 90%, capable of providing carbon black with added value. On a hydrogen selective enzyme hydrogenase sensor, verification was given on its sensitivity and response speed, but the discussion was interrupted because of difficulty in obtaining the enzyme. Naphthenic hydrogen storage and transportation media (easy in hydrogenation and dehydrogenation) were discussed, whereas the reaction promoting effect was identified in both of the super heating liquid film process and the membrane reactor system. Enhancement in output and efficiency may be anticipated if hydrogen-rich reformed gas is obtained by reforming methane (natural gas) by utilizing waste heat from a gas turbine of several MW capacity. Hydrogen liquefaction technologies using the magnetic freezing process was discussed as the fundamental research assignment, wherein fiscal 2000 has studied the basic design and optimal magnetic materials.

    Studies were conducted to find out hydrogen absorbing alloys with an effective hydrogen absorption rate of 3 mass % or more, hydrogen discharge temperature of 100 degrees C or lower, hydrogen absorbing capacity after 5,000 cycles not less than 90% of the initial capacity, applicable to stationary and mobile systems. The V-based alloy that achieved an effective hydrogen absorption rate of 2.6 mass % in the preceding fiscal year was subjected to studies relating to safety and durability. Since V is costly, efforts were exerted to develop TiCrMo alloys to replace the V-based alloy. In the search for novel high-performance alloys, endeavors centered on novel ternary alloys, novel alloys based on Mg and Ti, and novel intermetallic compounds of the Mg-4 family. In the study of guidelines for developing next-generation high-performance alloys, methods for creating hydrides with an H/M (hydrogen/metal) ratio far higher than 2 were discussed. Mentioned as techniques to produce such hydrides were the utilization of the hole regulated lattice, novel alloys based on the ultrahigh pressure hydride phase, new substances making use of the cooperative phenomenon in the coexistent multiple-phase structure, and the like.

    The paper described the fiscal 1996 developmental results of hydrogen burning turbine combustion technology in the hydrogen utilization international clean energy system (WE-NET) project. A test was conducted on an annular type combustor where oxygen is mixed with steam (inert gas) at burner and fired with hydrogen. Appropriate flame shape and cooling/dilution vapor distribution were attempted, and various data on combustion were measured for improvement. Mixture and flame holding were improved by developing a can type combustor (1) where oxygen is diluted with steam after firing oxygen and hydrogen around burner and by strengthening circulation in the combustor. Improvement such as appropriate steam distribution, etc. is needed. A can type combustor (2) was tested in which the premixed oxygen and hydrogen is supplied from scoop and fired with hydrogen. By supplying part of oxygen from the primary scoop, the residual hydrogen and oxygen concentration around the stoichiometric ratio can be reduced. Concentration of the residual oxygen can be measured by the absorption light method, but it is difficult to adopt the non-contact measuring method to hydrogen. An outlook for the gas temperature measuring method was obtained. 12 refs., 121 figs., 27 tabs.

    An ultrasonic probe with its point fine is navigated in blood vessels and body cavities by 3-dimensional ultrasonic signals (with the oscillator driven by transmission from a catheter for position detection) for the acquisition of accurate 3-dimensional ultrasound images in a less invasive way. The transmission and reception circuits are provided with circuits for ultrasound tomographic images and for navigation. Trial units are fabricated and tested for transmission waveform and reception performance. The scanner is rotated for the acquisition of intravascular 3-dimensional radial images. The scanner rotating rate is set at 30 rps for the scanner performance not to be affected by heartbeat and the rate is controlled by the observation unit which changes voltage for the control. The 3-dimensional display software program, thanks to the navigation function of the external probe, detects the external probe position relative to the small-diameter probe for the construction of accurate 3-dimensional images. Specifications for a total system, which makes full use of a navigation function, are compiled, consisting of a small-diameter probe and a body surface real-time 3-dimensional display. (NEDO)

    This paper describes the achievements in fiscal 2000 from the development of candidate low-temperature materials for liquid hydrogen transportation and storage (including mother materials and welds) for WE-NET. Evaluation tests were performed on material properties (mechanical properties, low-temperature embrittlement, and hydrogen embrittlement sensitivity) under room temperature and low temperature regions including liquid hydrogen atmosphere. Low temperature toughness of welds was assessed particularly to identify characteristics of different welding methods developed newly for improvements. The stainless steels and the mother materials of aluminum alloy selected as the candidates have sufficient characteristics even under the liquid hydrogen atmosphere, but the welds have lower low-temperature toughness, requiring improvement. For the stainless steels, since the amount of {delta} ferrite in welds affects greatly the low-temperature toughness, adoption of complete austenite type welding metal is effective. The reduced pressure electron beam welding method can enhance drastically the low-temperature toughness of stainless steel. For the aluminum alloy, it can be one of the alternatives to use an alloy system with composition of high low-temperature toughness. The friction stir welding method for the aluminum alloy was found to provide extremely high low-temperature toughness, which can be evaluated as a new welding method. (NEDO)

    The R and D were conducted of a grinding machine system of an environmental-friendly type in which no coolant is used or the amount of coolant is reduced, and the FY 2000 results were summed up. As to the ECOLOG grinding newly thought up, the roles were divided: the lubrication into a trace of the vegetable oil supplied onto the grindstone surface, cooling into a trace of the cooling water supplied to the structure, discharge of chips to the cooling water for bed table cleaning. By this, the amount of the cooling water becomes approximately 1/3 of that in the conventional grinding. Concerning the ECOLOG grinding using the usual grindstone, the grinding performance equal to that in the conventional grinding was confirmed. In the study for making the cooling water non-pollutant, the chlorine/sulfur free coolant was developed which includes no chemical substances designated by the PRTR law at all. It was confirmed that the grinding performance was almost the same level as the existing coolant which includes sulfur. In the study of the supply of coolant applied with ultrasonic waves, the result was obtained that in the optical glass grinding, the number of scratches decreased and the surface roughness improved even at the flow rate of coolant which is less than in the conventional grinding.

    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)

    Survey has been conducted to develop laser processing technology utilizing the interaction between substance and photon. This is a part of the leading research on photon technology development. The photon technology development is aimed at novel technology development highly utilizing the quantum nature of photons. In the field of laser processing, high quality photons are used as tools, special functions of atoms and molecules will be discovered, and processing for functional fabrication (photon machining) will be established. A role of laser processing in industries has become significant, which is currently spreading not only into cutting and welding of materials and scalpels but also into such a special field as ultrafine processing of materials. The spreading is sometimes obstructed due to the difficulty of procurement of suitable machines and materials, and the increase of cost. The purpose of this study is to develop the optimal laser technology, to elucidate the interaction between substance and photon, and to develop the laser system and the transmission and regulation systems which realize the optimal conditions. 387 refs., 115 figs., 25 tabs.

    According to the trend of car suspensions announced in 1989, not only sports cars but also sedans have extensively applied a multi-link type and a double-wishbone type which are to improve operation stability and comfortableness by reexamining all their fundamental structures. Active suspensions with electronic control have been put to practical use and adopted for the first time to mass-produced cars such as INFINITI'' and CELICA''. Concerning steerings, most types of light cars are now equipped with power steerings. Moreover, application of air bags has increased, and safety has been improved by commercialization of the first mechanical air bags in addition to the conventional electrical ones. As for brakes, more anti-lock brakes have been used for 4WD cars and low-displacement cars. Motorcars with a traction control system have consequently increased. Thus both the anti-lock brakes and the traction control system are contributing to the improvement in safety. 17 figs., 2 tabs.

Development of the photon technology aims at the modification of bonding conditions of substances by quantum energy of photon, and the new process technology for generating ultra- high temperature and pressure fields by concentrating photon on a minute region. Photon technology contributes to not only the conventional mechanical and thermal forming and removal machining but also function added machining (photon machining) in quantum level and new machining technology ranging from macro- to micro-machining, creating a new industrial field. This technology extends various fields from the basis of physics and chemistry to new bonding technology. Development of a compact high-quality high-power high-efficiency photon source, and advanced photon transmission technology are necessary.

Its features such as selective atom reaction, dense inner shell excitation and spacial high resolution by quantum energy are expected to provide innovative techniques for various field such as fine machining, material synthesis and advanced inspection technology. This wavelength region has been hardly utilized for industrial fields because of poor development of suitable photon sources and optical devices. The developmental meaning, usable time and issue of a hard photon reduction lithography were surveyed as lithography in ultra-fine region below 0.1{mu}m. On hard photon analysis/evaluation technology, the industrial use of analysis, measurement and evaluation technologies by micro-beam was viewed, and optimum photon sources and optical systems were surveyed. Prediction of surface and surface layer modification by inner shell excitation, the future trend of this process and development of a vacuum ultraviolet light source were also surveyed. 383 refs., 153 figs., 17 tabs.

    This paper reviews the current status from the standpoint of chemical engineers facing the coming of the 21st century, and surveys the paradigm for new scientific technologies. The criticism is mixed with unique opinions everywhere, such as `departure of students from scientific and engineering faculties is none other than the result of a market principle`, `national burden of trillions of yens should not be spent only under a justice of advancement of the science`, and `the global civilization itself has no other way but to change from the conventional expansive development type of the western country style to the internal development type of the oriental country style`. Values that define the paradigm for new scientific technologies may include such keywords as saturation in technology, baseless expansion of research projects, criticism on science, market principle, and centering human being. It should be looked at seriously that profit from research and development should exceed the cast invested therein in the future, and scientific technologies that serve truly the society should be aimed at. These efforts will result in one of the large pillars that support the future in which creation of new functions is aimed at as a result of structuring the new systems. Trying to overcome the environmental problems is one of them.

    This paper looks back the history of applications of laser processing in the automobile industry, and introduces contents of some particularly unique applications from among them. The CO2 laser and YAG laser that are used mainly have increased their outputs with the times, and 50-kW CO2 laser and 4-kW YAG laser have now become available commercially. The laser processing has become used widely for cutting purpose in Japan, which is in contrast with their high application to welding in Europe and America. Cutting thick plates has been developed recently, which is applicable to plates as thick as about 25 mm. A flexible system in which YAG laser is combined with an optical fiber/articulated robot is operating for three-dimensional shape processing. Automobile makers are adopting laser processing for welding in place of the electron beam welding that has been used conventionally. The process is used also for a number of other applications including surface reformation, such as surface quenching for cylinder liner, and valve seat padding. 8 refs., 8 figs.

    The paper described the results of the FY 1999 development of polymer electrolyte fuel cell and several 10 kW class dispersed generation system. The humidification of the cell body is the internal humidification method in which water is directly supplied to cell, which makes the cell life long. The cooling using latent heat of vaporization of the water supplied makes the temperature distribution inside the cell face homogeneous. In the test for long life, the system was stably operated at voltage lowering speed of 11mV/1000h. The optimization of water supply structure in the stack increases the latent heat cooling amount and makes the temperature distribution inside the cell face homogeneous. The reduction of CO concentration in reformed gas is extremely important for improvement of cell performance and long-term stabilization of cell voltage. By the two-stage structure selective oxidation device, the CO concentration at inlet, 5,000 ppm, can be reduced to below 10 ppm at outlet. In the demonstrative experiment on the several 10 kW class dispersed generation system, efforts for reduction in size of structural equipment and package were made, and a possible size of 200*150*180cm was obtained.

    Research and development was conducted aiming at the establishment of a system to enable the high-efficiency expression of the gene products of P. horikoshii OT3 and A. pernix K1. In an effort to develop a high-efficiency protein expression system with Escherichia coli acting as the host, studies were made about the expression of hyperthermophile protein by arginine rare codon elimination, and Ph FEN (flap endonuclease) was successfully overexpressed. In the development of Bacillus strains, screening was conducted for novel hosts, and a library was constructed for a screening task suitable for hyperthermophile-derived protein production. A system was also constructed capable of the high-throughput expression of various kinds of genes using Bacillus brevis. In the study of the expression of hyperthermophile-derived genes using T. thermophilus, promoter replacement resulted in an approximately 2-fold increase in representation at the maximum. Moreover, studies were made about the length at which foreign genes were efficiently incorporated into the T. thermophilus genome. (NEDO)

    Described herein are the FY 1999 results of the R and D project for development of intellectual materials and structural systems, where the fibrous or leafy sensor material or element (muscle) is integrated with a structure of an advanced material (skeleton) to process and control information (brain). The program for development of the health monitoring technologies develops the fine optical fiber (diameter: 40{mu}m), which is on a level with the conventional 125{mu}m-diameter fiber in strength and fatigue characteristics, for the high-performance sensor systems. The self-diagnosis of soundness, e.g., detection of impact loads and damages, is attempted using the fine optical fibers embedded in the composite structures. The program for active-adaptive control of smart structures investigates control of vibration and noise for beam structure elements, using the theoretical model developed for shape memory alloys. The vibration tests are conducted, where a distribution type sensor is used for active-adaptive control of soft structures, and the good results are produced. The program for development of actuator materials and elements produces high-strength, high-toughness PZT and PNN-PZT sheets of uniformly distributed thickness by the doctor blade method. (NEDO).

    Safety technology is necessary and indispensable for future materialization of a hydrogen energy system. The survey was made from a viewpoint of safety technology in refining hydrogen at low temperature and in storing it in a low temperature liquid state. Japan has so far had no experiences for the handling and consumption of liquid hydrogen except the partial use at laboratory. Accordingly, collected here was literature on the storage, transportation, handling, low temperature refining of the liquid, etc. The present state of technology in Japan and abroad was grasped and items in the safety relation were picked up. As to the existing literature on the hydrogen relation, there is much literature on the U.S. NASA project, and there is also much on practical business details such as the handling of a large quantity of liquid. Therefore, from each literature mostly on the above, the literature on the liquid storage, transportation use storage tank and refining method was reviewed and arranged, and at the same time, the items were picked up of the safe disposal method, disaster prevention relation, and measuring relation. The paper also arranged the results of surveying hydrogen physical properties and equipment materials which are closely related to safety general, in particular, and examples of disaster. (NEDO)

    This paper discusses low-temperature storage of hydrogen, and safety in the refining stage thereof. Discussions were given on a device to discharge safely hydrogen evaporated from a liquefied hydrogen storing tank rolly. A testing equipment of a 1/10 size of a full size equipment was fabricated on a trial basis. The equipment was used to test discharging a gaseous mixture containing hydrogen at concentration of about 2%, while air is being supplied from a blower directly connected to a gas motor (rotating on gas pressure) with treatment rate of 15 Nm{sup 3}/h. In order to keep the hydrogen concentration below the lower explosion limit of 4%, uniformity in the spatial distribution of the concentration is important. Full consideration should be given thereto in future designing works. With a cryogenic adsorption refining device for hydrogen, oxygen content is adsorbed, and hydrogen is refined. During regeneration of the adsorption device, oxygen is discharged. Experiments on regeneration methods were performed for comparing and discussing oxygen discharge behavior by using three systems: nitrogen purge, hydrogen purge, and temperature raising. Cases were found in which oxygen concentration in the exhaust gas exceeds the lower explosion limit of 4%. There is a number of important assignments to assure safety, including specific measures to prevent the above excess, reciprocal influence of multiple impurities, and removal of ignition sources. The present experiments have great significance in providing fundamental items of information. (NEDO)

    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)

    From among researches on hydrogen manufacturing technologies using thermo-chemistry in the Sunshine Project, discussions were given on equipment materials, with the second-stage reaction in the iodine system cycle as the object. This paper describes achievements in fiscal 1979. The reaction produces MgO, I{sub 2} and O{sub 2} from Mg(IO{sub 3}){sub 2}. Corrosion tests were performed by using test pieces made of Ni alloy, iron-Ni-Cr alloy, Ti alloy, Zr alloy, Nb and Ta. These materials are thought to have excellent corrosion resistance in high temperature gaseous phase composed of iodine, oxygen and water. Corrosion tests were carried out also by using sheet formed test pieces of 24 kinds of alloys and six kinds of commercially available non-ferrous metallic materials in different temperatures and atmospheres, mainly the iodine plus oxygen plus H{sub 2}O mixed gas atmosphere at 600 degrees C. The corrosion resistance of the tested materials can be divided into three ranks. Materials having relatively good resistance were Ni-50Cr alloy and Co group alloy. Materials having good corrosion resistance are very little affected by water content. The higher the temperature, the more the metal corrosivity has increased. Preliminary discussions were given on pipe formability in materials having good corrosion resistance as the equipment piping materials. Their mechanical properties were also tested.

    This paper describes research on materials of equipment for the second stage reaction in relation with development on a hydrogen manufacturing technology by using the iodine system cycle in the thermo-chemical method. The second stage reaction produces MgO, I{sub 2} and O{sub 2} by decomposition of Mg(IO{sub 3}){sub 2} at 600 to 650 degrees C. Corrosion tests were carried out by using 25Cr-20Ni steel and Ni-50Cr alloy having shown relatively high corrosion resistance in the researches to date, which were added with trace amount of different alloy elements. The tests were performed in gas mixture of I{sub 2}, O{sub 2} and H{sub 2}O at 600 to 700 degrees C for 48 to 192 hours. The average corrosion rate of 25Cr-20Ni steel was reduced by adding Y(0.2%), Ca (0.2%) or Si+Al (1%Si+1%Al), by which relatively uniform corrosion pattern was shown, and the corrosion resistance was improved remarkably. The average corrosion rate of 25Cr-20Ni steel showed a trend of increasing by adding Si and Nb, and non-uniform corrosion like pitting has occurred, revealing that it is not preferable from the aspect of corrosion resistance. The average corrosion rates of the tested materials tended to become somewhat greater under heat insulated condition than under continuously heating condition. Effect of Mg(IO{sub 3}){sub 2} deposition is very small. (NEDO)

    Atmospheric concentration of CO2 is increasing, and discussions are urged on measures to suppress emission of CO2 into atmosphere. While different CO2 fixing technologies may be conceived, there is a technology to utilize CO2 absorbing capability of ocean by discharging and dissolving CO2 artificially into middle layer of the ocean to separate CO2 from atmosphere. This technology is one of the technologies which are promising in the aspects of technology, economic performance, and possible amount of CO2 reduction. However, it is difficult to say that scientific and technological discussions have been given sufficiently on behavior of CO2 discharged into the ocean, effect of the discharge on environments, and CO2 separation capability of the ocean. Therefore, in the present research and development, a 'technology to forecast environmental effect in areas in the vicinity of CO2 discharging points' is developed to serve for acquiring technological prospect on the feasibility to realize the CO2 ocean separation by discharging CO2 into the middle layer of the ocean. The present fiscal year has performed researches on the following research and development items: elucidation of behavior of liquefied CO2 when discharged into the ocean, CO2 feeding and diluting technologies, indoor experiments on the effects of CO2 on ocean living organisms, and development of a model to forecast environments in areas in the vicinity of CO2 discharging points.

    The purpose of the project in FY 1998 is 'Experimental verification for EV spread promotion.' Two of a 3-month experiment were conducted in Yokohama MM21 area (Yokohama, Kanagawa) and in Tama Newtown (Inage, Tokyo) using a total of 100 (50 each) small EVs. The development was aimed at of an urban type rental-car system in Yokohama and of a car-sharing type second-car system for residential in Inage. As to these responses to ITS technology, the basic vehicle operation system was made common in both areas, and the daily use system was made a regional system considered of purposes of use, regional characteristics, etc. The experimental verification was worked on as almost expected in terms of the vehicle management, monitor assessment, responses from persons concerned in both areas. Therefore, it is said that the R and D have almost reached a point where there can be seen a possibility of system commercialization. Through the experimental verification, the development was able to be smoothly promoted of the basic technology and element technology which are thought to be needed for the commercialization of EV. From the experience of this experimental verification, it is judged that it is desirable to tackle the commercialization by a membership system when the commercialization of EV joint use system is planned in future.

    The coal utilization is expected to make substantial growth according to the long-term energy supply/demand plan. To further expand the future coal utilization, however, it is indispensable to reduce environmental loads in its total use with other energies, based on the coal use. In this survey, a regional model survey was conducted as environmental load reduction measures using highly cleaned coal which were taken in fiscal 1993 and 1994. Concretely, a model system was assumed which combined facilities for mixed combustion with coal and other energy (hull, bagasse, waste, etc.) and facilities for effective use of burned ash, and potential reduction in environmental loads of the model system was studied. The technology of mixed combustion between coal and other energy is still in a developmental stage with no novelties in the country. Therefore, the mixed combustion technology between coal and other energy is an important field which is very useful for the future energy supply/demand and environmental issues. 34 refs., 27 figs., 48 tabs.

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

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

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

    This report describes the vehicle autonomy by using artificial intelligence (AI) technology. Owing to a remarkable progress of AI technology, it is forecasted that driving support system will be introduced into the market till 2000, and higher autonomous navigation system will be introduced since about 2010. Autonomous vehicles have capacities of recognizing the outside world and of navigating roads by themselves, and with their enfanced environment adaptability the road transportation in the future is expected to be much more safer than in the present. The autonomous vehicle can warn its driver of potential dangers and correct operational errors of the driver. In order to realize such autonomous vehicles, extensive researches on perception systems, decision making systems and driving support systems are needed. 9 refs., 10 figs., 1 tab.

    We have developed parking assist system, which informs a driver the closing point and distance to the objects such as other vehicle, wall and pole around the own vehicle at parking area and makes parking maneuverability easy. This system is based on the range detection technology using ultrasonic wave sensor. We have improved the detecting ability in short range of about 20cm by reducing the reverberation of transmitting wave signal and controlling sensitivities of signal intensity and threshold line. We will show mainly the improvement of short range detection of ultrasonic wave sensor, and briefly the performance of parking assist system. 1 ref., 14 figs., 1 tab.

    The burning area of propellant grain is one of the most important parameter in conducting of design on solid rocket performance. However, it has been difficult to calculate the burning area of propellant grain with precise and speed by geometrical way since most of propellant configuration have been adopted as complicated. In the present study, the simulation system was developed and produced, which was adapted `particle chasing method` to and made ot compute the burning area transition. Moreover, the reliability on computation by the system was check up on. It was found that the discrepancy of calculation between by the geometrical way and by the system was less than 1%. (author)

    The materialization of computer integrated manufacturing (CIM) requires an establishment of its systematizing system, i.e., architecturer and planning of the infrastructure to support it and basic engineering to support the informational utilization. The CIM architecture is classified into management and system structure, strategic planning method, System development introduction method, etc. The infrastructure aims at epoch-makingly heightening the productivity and speed by integrating the production planning, engineering design, accounting, sales, general business and affairs, production engineering, production activities, and activities of suppliers and clients. The informational utilization support engineering comprises the management support tool, decision making support tool, application development tool, etc. What is important is to establish a system of systematizing engineering in order not to be behind the strategic activation era of information to come. 17 refs., 4 figs., 1 tab.

    Waste disposal by incineration is in wide use, inevitably discharging the unburnt portion or ash as the residue, and the residue contains heavy metals and dioxins. New slagging technologies capable of dealing with the situation, respecting in addition the effective use of resources, are now attracting attention, and are coming into popular use. IHI has already developed three types of melting technologies, which are the residual carbon combustion type, the joule-heating furnace type, and the coke-bed furnace type, and has already delivered to clients some facilities using these technologies. In this report, the three types are outlined, and the joule-heating furnace is taken up to explain the process of development up to commercialization. In the joule-heating furnace, molten slag (resistivity several ohms/cm at 1300degC) is electrified for the melting of ash by joule heat, and the result is a high-quality slag containing less chlorine thanks to the electrochemical decomposition. Studies were conducted about exhaust gas cleaning, silent operation, and cost performance (using only one electrode), etc., by operating 2.4t/d and 10t/d demonstration plants, and the efforts have culminated in the commercialization of the technology. 6 refs., 9 figs., 7 tabs.

    The latest measurement equipment and repair method were introduced into the work area of all refractories in the process of torpedo cars, hot metal preliminary treatment, hot metal pans, secondary refining, and cast pans so as to improve the cost of the newest advanced steelmaking refractories. As a result, the refractory cost could be reduced by 10%. This paper introduces the improvement in RH refractories and refractories for hot metal preliminary treatment. As for basic items, in addition to the visual observation, the thickness of refractories was quantified using equipment (laser profile meter, thermotracer, and NS sensor) for the furnace stop in the minimum remaining length. An ITV was also installed in the facilities where the visual check is difficult to carry out. Repair is mainly done by spraying. A thermal spraying repair method with high durability was used for the repair. A method that relieves a thermal shock was used for preheating. Moreover, measures that make the temperature gradient in the thickness direction uniform by using newly developed microwave drying equipment were taken for drying of unburned refractories. 4 refs., 13 figs., 2 tabs.

    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.
