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

Examination was conducted in detail on an MHD generation system by coal combustion, with the results reported. Concerning a gas table calculation program in coal combustion, it was prepared assuming 100% slag removal ratio in the combustor as the primary approximation. A combustor for MHD generation needs to efficiently burn fuel using high temperature pre-heated air as the oxidant, to fully dissociate/electrolytically dissociate seed, and to supply to the generation channel a high speed combustion gas plasma having a high electrical conductivity which is required for MHD generation. This year, an examination was conducted on technological problems in burning coal in an MHD combustor. As for the NOx elimination system in an MHD generation plant, an examination was made if the method studied so far in MHD generation using heavy oil as the fuel is applicable to coal. Also investigated and reviewed were various characteristics, change in physical properties, recovery method, etc., in a mixed state of seed and slag in the case of coal combustion MHD. (NEDO)

Military and social restrictions imposed on Japanese scientific research following the second world war made nuclear or particle physics experiments almost impossible. However, the (Japanese) theoretical achievements of the 1940s considerably buoyed this group, namely two-meson theory, super-many-time theory and covariant renormalization theory. Economic conditions were also difficult with high inflation throughout the 1950s. Printing and distribution problems and paper shortages reduced the circulation of scientific journals, but theoretical work progressed well even in isolation. Within Japan, a circular called Soyrushiron Kenkyu (elementary particle theory research) became a valuable medium for exchange of new ideas and information. A Research Institute for Fundamental Physics, the first of several Japanese research institutes, was opened at Kyoto University in 1953, when a major international conference was held there. The second half of the 1950s was a time of expansion and consolidation for particle physics in Japan. (UK)

Ceramic gas turbine (CGT) is superior in the aspects of high efficiency, low pollution, multi-kind fuel performance, small size, and light weight. Its utilization field is broad, whereas putting it into practical use at an early time is desired from the viewpoints of energy conservation, reduction in CO2 emission, resource conservation, and economic influence. The utilization field of CGT may include cogeneration and portable power generator, but putting it into practical use requires that it be superior in environment protection performance such as gas exhaust, noise and vibration, economic performance, safety, and adaptability with the utilization fields. From such a viewpoint, discussions were given on its adaptability with the society based on different characteristics of the CGT, and other conditions such as related laws and regulations. The first edition investigated the developmental trends in ceramic materials, and the second edition studied the CGT utilizing systems, in particular, the status of utilization and proliferation of the current cogeneration systems. The edition evaluated various conditions required for conceptual design of the system. The third edition put into order the environmental regulations and future trends in order to identify the effect of introducing the CGT. (NEDO)

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

Methods: We evaluated 3 subjects using the diagnostic criteria for bv-FTD, and their caregivers retrospectively provided data to calculate the Autism-Spectrum Quotient, Japanese version [Wakabayashi et al.: Shinrigaku Kenkyu 2004;75:78–84]. We also compared these data with those obtained from 3 individuals with Alzheimer’s disease. Results: All 3 patients met the criteria for bv-FTD and had a higher Autism-Spectrum Quotient score than did comparable Alzheimer’s disease subjects. Conclusion: It is possible that some senile persons with frontotemporal lobar degeneration-like maladaptive behavior may suffer from subclinical AS.

Examination was conducted in detail on an MHD generation system by coal combustion, with the results reported. Concerning a gas table calculation program in coal combustion, it was prepared assuming 100% slag removal ratio in the combustor as the primary approximation. A combustor for MHD generation needs to efficiently burn fuel using high temperature pre-heated air as the oxidant, to fully dissociate/electrolytically dissociate seed, and to supply to the generation channel a high speed combustion gas plasma having a high electrical conductivity which is required for MHD generation. This year, an examination was conducted on technological problems in burning coal in an MHD combustor. As for the NOx elimination system in an MHD generation plant, an examination was made if the method studied so far in MHD generation using heavy oil as the fuel is applicable to coal. Also investigated and reviewed were various characteristics, change in physical properties, recovery method, etc., in a mixed state of seed and slag in the case of coal combustion MHD. (NEDO)

Before a welfare facility is introduced into a home, studies should be sufficiently conducted about the circumstances of daily life, not only of the aged user but also of the family members who take care of the aged user. In the development of handrails, it is found that plastic foam containing wood flour presents the feel of wood, easy to bend when heated. Materials are investigated for flexural strength, and ABS (acrylonitrile butadiene styrene) is chosen as the suitable material. As for devices to assist toileting, a system is developed under which the patient's legs are raised. Since there are arguments for and against the operation itself of mechanically raising a patient's legs, however, efforts will continue to develop much advanced systems. In the study of walk and transfer behavior, a toilet frame mockup is designed and manufactured, which is for collecting data. In an preliminary experiment, tests are conducted about a transfer from a chair to another and, assuming a physically handicapped patient, a transfer from a wheelchair. The data thus collected are to be subjected to analysis and image processing by the use of measuring sensors. Development is described of interfaces, for use in devices to serve as information mediums, which consider the cognition characteristics of the aged people.

The research aims to develop a new-type high-efficiency reactor for direct coal-liquefaction from a reaction engineering viewpoint and, at the same time, to settle problems expected to occur in industrializing this technique. The research items are Item 1 on the analysis of characteristics of a tubular continuous reactor and Item 2 on high-activity catalysts. Under Item 1, on the assumption that liquefaction reaction is dominantly a reaction in a continuous phase, a reactor is selected in consideration of homogeneous-phase reaction, and operating conditions are set according to the selected reactor and to the liquefaction reaction characteristics. A somewhat large Re number is assigned to the paste. Since the hydrogen partial pressure lowers with the progress of reaction, hydrogen is resupplied at the middle of the reaction tube. The volume of gas increases toward the final stage of reaction, decreasing the continuous phase holdup. Since it is undesirable to let the decrease stand, a vapor-liquid separator is provided for the control of the gas volume. In this fiscal year, investigation is conducted into details so as to determine if the reactor is equipped with intended characteristics. Under Item 2, the iron ore is deemed to be the most promising as disposal catalysts for liquefaction. In this fiscal year, studies are conducted to disclose the activity etc. of catalysts of this type. (NEDO)

Opinions were heard from residents about residences designed for aged people. According to their physical conditions, residents of advanced age may be classified into four groups, that is, 'Aged person who is self-reliant,' 'Patient who can walk using a walking stick or handrail, with a caregiver,' 'Patient who rides a wheelchair, with a caregiver,' 'Patient who is bedridden, with a caregiver.' The collected data will be effectively utilized in the future for planning residences that respect an advanced age. The difference between the four groups ensues from difference in human relationship in the residences and in movement and caregiving in daily life. When a residence in which a patient lives with the family is set forth for premise, what is important is to consider the request of the patient that the residence be functionally perfect and, at the same time, attention must be paid to the psychological desire that the residence be equipped with what a home is generally supposed to offer. Emerging increasingly definite out of the research conducted this fiscal year are policies towards the development of, and the feasibility of, a remotely controlled medical assistance system with patients allowed to stay at home and terminal equipment therefor. An experimentally constructed movement assistance unit is tested at Welfare Technohouse Kamogawa, and findings are obtained about the safe use of a barrier-free condominium thanks to such functions as motor-assisted walking, assistance for standing-up, collision avoidance, etc. (NEDO)

Old people's need for illumination is sufficiently covered by the JIS-stipulated illumination range. Although the minimum safe limit for the aged is serval times higher than that of the young, yet electricity saving may still be enhanced by proper adjustment without spoiling amenity for the aged. A hard floor puts a burden on the knees. The degree of fatigue due to the use of footgear is dependent not only on the shape but also on the user's habit. The transfer equipment seat surface height, if improperly set, oppresses the user psychologically and physiologically, the burdens heavier when the seat is lower. As compared with transfer aboard the wheelchair, a horizontal movement on the seat surface by the use of arms (fore and aft, right and left) demands less physiological burden. The above-said matters are taken into consideration when designing transfer equipment. As for emergency information systems, it is necessary to study seat pressure distribution, change in body temperature in a bath, change in blood pressure on the stool, and to develop a pulse counting simulator. A life space simulator and welfare utensil fitness evaluation are discussed. Also discussed are the development of a simulator for the comprehensive evaluation of motorized wheelchairs for their capability to encourage self-reliance, monitoring systems, and supervising/reporting systems (toilet irregularity annunciators etc.).

Research is conducted into burdens to be imposed on the nurse and the attended person during nursing activities and into measures to lighten such burdens, and basic data are collected about physical strains to be produced when raising a patient on the bed, pushing a wheelchair, and about stool shapes appropriate for the aged. In a study about escape from a disaster, many shortcomings are discovered requiring remedy, such as difference in height and doors failing to open in case of power outage. For communication in case of emergency, it is concluded that the most promising method will be a combination of a mobile computer and handyphone system. A photoelectric pulse wave monitoring system and an acceleration sensor-equipped water bed, on which the patient lies unrestrained for the measurement of heartbeats and respiration waveforms, are developed. A concept wheelchair is under development which will be a 2-motor 4-wheel design, to be equipped with a steering wheel and a vertically movable seat which will facilitate boarding and alighting. Many projects are in store for fiscal 2001, which include the development of a system to ensure sitting position stability and an automatic pressure belt for the prevention of orthostatic hypotension. A multiple function bed is under development for domestic use, which will be provided with a discharge system (automatic toilet) whose mechanism is quite sophisticated. (NEDO)

The New Sunshine Project, promoted by Ministry of International Trade and Industry, has developed a 300 kW ceramic gas turbine CGT302 (biaxial, regenerative type) in March 1999, which attains a turbine inlet temperature of 1,334 degrees C and thermal efficiency of 42.1%. The conditions of optimum utilization of the system are studied for eventual commercialization and spread of these systems, including analysis of load types for specific purposes, prediction of operation management, economics of CGT, environmental impacts, and possibility of diversification of the fuel. The CGT cost analysis results indicate that a CGT system is well viable when the incremental initial cost of the power generator is kept below 70,000 yen/kW over the conventional system. The system can be doubled in scale at the largest. It can be further scaled up, when hybrid members with metallic materials are used. CGT is a basic technique for (system energy). In other words, the 21st. century will be the age of (system energy), i.e., (gas turbine). (NEDO)

With an objective of realizing super large capacity recording technologies largely exceeding the current limits of optical recording and magnetic recording, studies were conducted on application of near-field optics. In the study on recording by using near-field light, it was verified that a mark with approximately the same size as an aperture diameter can be formed on a phase change recording film when a fiber probe with an aperture diameter of about 200 nm is used. However, it was found that the recording using this system takes excessive amount of time. When laser light collected on an objective lens was irradiated pulse-wise, a mark with a minimum width of about 20 nm was observed with high contrast. This will mean that a record with recording density of one terabit/in {sup 2} can be read out. Other studies performed include those on evaluation of effects of polarized light and surface shape on near-field read-out, simulation, mechanism of crystallization in a phase change recording film, recording and playback with ultra-high resolution by using a conformable near-field aperture, fabrication of a flat aperture type near-field light probe array, and the evaluation thereon. 22 refs., 27 figs.

Researches are conducted for the development of a technology of producing useful gases such as acetylene, hydrogen, carbon monoxide, etc., from coal by the use of the high temperature and high-density energy of the plasma jet. In an experiment using a 100kW 3-port plasma-aided gasification unit, rapid quenching tests are conducted using hydrogen and helium, where the reaction furnace is changed, the specimen feed device is changed, and the plasma torch head is replaced by a high-power head. In a test of the coal specimen, it is found that rapid quenching exerts a great effect on the prevention of re-decomposition of the generated acetylene into hydrogen and carbon black and that a rise in the hydrogen partial pressure results in a great decrease in the quantity of acetylene generated. The said torch head replacement increases the rate of the coal specimen infiltrating into the plasma flame, which brings about an increase in the quantity of acetylene generated. It is found after all that the conventional acetylene yield of 34g/kWh increases to 59g/kWh in a rapid quenching test in which the specimen is dried Akabira coal and the plasma is an argon gas plasma containing 40% hydrogen.

This paper summarizes the general survey mainly conducted by FCRA (Fine Ceramics Research Association) in fiscal 1996, and the joint research results with some universities, from some R and D on synergy ceramics. Silicon nitride based ceramics expressed the same high thermal conductivity as metal by seed crystal addition, grain growth control and orientation control of sheet lamination. For its practical use, study was made on control factors of material, formation and sintering. Ca2Y2Si2O9 single crystal was prepared by float-zone method to determine its crystal structure. No volume change due to high-temperature phase transition as thermal expansion was found. In carbothermal reduction- nitridation of SiO2, addition of Si3N4 seed powder increased a reaction rate and formed uniform particles with an isotropic shape. An average particle size was dependent on the size and number of fine particles in seed powder. Addition of both Si3N4 and Fe compound could change a particle shape from a spherical grain to an elongated grain. A spherical Fe-Si metal grain was found on the tip of an elongated grain. 66 refs., 73 figs., 13 tabs.

This paper describes research achievements in fiscal 1979 in research on hydrogen fueled automobiles as a research on hydrogen energy subsystems. The previous fiscal year has researched heat insulation methods to reduce evaporation loss from a hydrogen tank, prototype liquid level meters, prototype feed pumps (especially material selection for sliding parts) and a flow rate control method. Fiscal 1979 performed measurements of temperatures in different parts in the tank to elucidate how the heat makes invasion. Measurements were performed for the pump on suction valve behavior, internal pump compression force, liner temperatures, and leakage amount. The status of operation was identified and a high performance pump for use in very low temperatures was developed successfully. The pump has high delivery pressure, good durability, and capability of fine adjustment in the delivery quantity. This made the direct injection system for hydrogen fuel possible. Injection of hydrogen into an engine was possible by vaporizing liquefied hydrogen and supplying it as a low temperature gas used at 0 to -40 degrees C. The system has high efficiency. Fuel feed control was possible at the same level as in the existing automobiles. The prototype direct injection system can handle stably the load in actual cars. Material for the fuel tank is an important problem in terms of weight, whose solution is urged. (NEDO)

The research was conducted jointly with Europe of a catalyst which enables clean combustion and NOx removal in polluted gas in combustion flue gas, etc. Reformation of mordenite and {beta}-zeolite was done by ion exchange, ion implantation, and membrane formation. A catalyst was searched for to obtain reducing agents, C5-C8 components, by decomposing light oil. Saponite, clay compound, showed by copper and silver ion exchanges approximately 50% of activity under 20,000h{sup -1}, C3H6 reducing agent, and without steam. The effect of the temperature of sintering on NOx selective reductionality of silver-carrying alumina catalyst was studied, and in sintering at 800degC, activity increased. When using conductive oxides like ruthenium oxide for electrolyte, NO decomposition selectivity increased. As to the functional layer carried above the Pd electrolyte, iron oxide and magnesium oxide increased NO decomposition selectivity. PdO and rare earth oxides forming compounds controlled variation of activity by dissociation/reoxidation of PdO. As to PdO/Gd203, the initial methane combustion activity was favorable, but there was seen deterioration with age. 271 refs., 281 figs., 58 tabs.

This report describes the fiscal 1976 research result on weather survey for solar energy systems. Study was made on preparation of the global solar radiation (GSR) map of Japan. To obtain the estimation equation of GSR based on related weather data, analysis was made on data at A type GSR observation sites and related weather data. As some factors effective for estimating monthly mean GSR, a relative sunshine duration, snowfall index (ratio of days more than 10cm in snowfall) and solar altitude index (sine of solar altitude at culmination hour) were selected. The estimation equation was prepared on the basis of these above factors. GSR was affected by relative sunshine duration exceedingly, snowfall by 12%, and solar altitude difference by 6% within an error of 5%. The monthly and annual GSR maps were prepared every site by the above calculation. The continuous observation results in Kagoshima and Fukuoka by recording direct pyranometers are presented. Scattered solar radiation is defined as the difference between simultaneously measured GSR and direct solar radiation. Weather data preparation in Fukuoka for design of solar cooling/heating and hot water supply systems is also described. (NEDO)

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

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

This paper summarizes the text of the research result report in the separate volume II-1 from among the fiscal 1998 report on the achievement made on researching and developing a molten carbonate fuel cell (MCFC) power generation system. For the AC-DC type system whose high performance and large capacity stacks are being developed, detail designs were made on 250-kW class stack module assembly and installation procedure. At the same time, processing and forming were continued on such main components as electrodes, electrolyte plates and separators. The cells were assembled as modules, sintered, installed and adjusted. Aids were given by the process and control (PAC) test on devices and piping of the fuel cell system block. Cell life extension is also under study. For the parallel flow type stack, two 250-kW stacks were fabricated, and an overall adjustment test was begun thereon in March. For the reformer, an internal reforming system was developed for the 200-kW class system, whose adjustment test is scheduled for April 1999. Capacity increase is also under discussion. For practical use of MCFC, stack life of 40,000 hours is said required. The current status is at the level of exceeding 10,000 hours, but the necessity is seen in suppressing voltage drop associated with lapse of time. (NEDO)

This paper explains the results of research on direct liquefaction reaction of coal in fiscal 1981. The direct liquefaction is a reaction of three phases, gas-liquid-solid, under high temperature and high pressure. A tube type was employed in order to increase volume efficiency of the reactor, the continuous phase disperse number was decreased in order to bring it close to plug flow, and the paste Re number was increased to some extent in order to prevent sedimentation of coal particles. Hydrogen was supplied from the tube halfway for the purpose of supplementing the lowering of hydrogen partial pressure with the progress of reaction. A gas-liquid separator was installed so that increase in gas quantity was controlled in the rear stage of the reactor. As for catalysts, iron ore-sulfur system was examined which was promising as a disposable catalyst in place of the conventional iron system. Effect of catalytic addition was clearly recognizable in comparison with non-catalytic, with an exothermic peak observed comparable to the coal hydrogenation reaction of 350-420 degree C. Its catalytic effect was also presumable from the high pressure differential thermal analysis curve. The catalytic mechanism in the case where sulfur is added to hematite and limonite is similar to that of Fe{sub 2}O{sub 3} - sulfur catalyst, with the center of activity supposed to be Fe{sub 1-x}S. The catalytic effect is largely dependent on the particle size. (NEDO)

Research on the transmission and management of information on those who necessitate nursing care will lead to the development of computer-aided nursing and welfare supporting systems and this in turn will help businesses who provide aged people with service they require for the enhancement of nursing care at home and at facilities for aged people to enjoy independent, unaided living. It is important to prepare liaising methods and coordinate with physicians in case of physical condition suddenly turning worse. Exchange of data at a visited place is important for a visiting nurse, and handling of information on such an occasion has to be easy and rapid to ensure high efficiency. When transmitting or receiving data on patients via PHS (personal handyphone system) or handyphone system, transmission of large-capacity data such as pictures should be avoided. In case a picture has to be transmitted, it should be compressed. ISDN (integrated services digital network) is preferred in all cases. The IEEE1394 interface is deemed to be the best for automatically transmitting as digital data the pictures etc. collected from other measuring instruments on nursing welfare and nursing assisting systems. It is necessary, however, to watch the development of digital interfaces in the future. (NEDO)

A joint research had been carried out with a subsidy from the Agency of Natural Resources and Energy since fiscal 1988 to fiscal 1995 on the direct iron ore smelting reduction process (DIOS process). The process utilizes coal directly as a process to use the strong points and supplement the weak points of the blast furnace process. During the period, a pilot plant had been operated since 1993. Upon having completed the feasibility study, this paper reports the result thereof. The main facilities consist of a smelting and reducing furnace of iron bath type, a spare reducing furnace of fluidized bed type, and a preheating furnace. The former two furnaces constitute a unit structure with the two furnaces connected vertically. The pilot plant achieved a three-day continuous operation producing 500 tons of iron every day. The production rate reached 21 tons an hour at an upward oxygen blowing velocity of about 13,000 Nm {sup 3} per hour. The coal unit requirement showed a result of <1000 kg/t for high VM coal and <900 kg/t for low VM coal. These results verified a possibility that this process can supplement or replace the blast furnace process even for a production scale of 9000 tons a day. 7 refs., 15 figs., 3 tabs.

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

A number of technological hurdles exist in the process of practically applying the fundamental researches, wherein risks for private business entities to promote the technological development are not at all small. The present surveys are intended to elucidate the actual status as to how a practical application process for technologies is positioned in the series of research and technological development activity floats by private corporations, and what kinds of problems are present, to serve for discussing the way the future supportive environment improvement should be. The 'practical application processes' in private corporations were put into order and analyzed, using as the base the existing study results relative to technological innovation mechanisms. Investigations ere performed on the existing Japanese research and technological development supporting institutions for the practical application processes employed by the private corporations. The result was used for reference of discussing the problems therein. Furthermore, it is indicated that, in the R and D strategies in the U.S.A., profitability is placed as the largest target by means of strengthening the linkage between research and commercialization. This has resulted in decline in the fundamental researches, for which discussions are developed currently. This paper reports investigations on the actual status of business enterprises in the practical application processes. (NEDO)

This project aims at development, demonstration and utilization of waste recycling technologies. This report summarizes the fiscal 1998 results. The test/demonstration plant for separation and removal of foreign materials was constructed for effective use of waste building wood, and its optimum operation condition was studied. Although some foreign materials exists, 90% of waste building wood chips were separated and recovered through some improvements for the plant. An advanced separation technology is expected. As for fibering technology, fibers with target compression strength were obtained from cedar chips through a disintegration experiment using a newly developed refiner plate. Although the compression strength of fibers obtained from waste building wood chips was slightly poor, it is attained by increasing the target specific gravity of light- weight wooden materials by nearly 10% from 0.1. As for fiber orientation technology, as the tension of a forming belt was adjusted to achieve sufficient width compression, nearly 90% of the target compression strength was attained. A width compression method remains to be solved. (NEDO)

This paper describes the result of discussions on hydrogen fueled automobiles in fiscal 1978. Hydrogen fueled automobiles have a difficulty in developing methods for transporting hydrogen, whereas the liquefied hydrogen method and the metal hydride method are being studied in parallel at the present. It is also necessary to solve such basic problems as the method for supplying hydrogen to engines, the injection method, and countermeasures for abnormal combustion. Safety assurance is also important. Very little information is available presently on methods for storing hydrogen inside a car and supplying thereof, which are required for evaluating utilization of liquefied hydrogen to automobiles. Demonstrative surveys and researches are required to acquire basic materials for hydrogen feeding methods in broader meaning including storage and control. Therefore, fiscal 1977 has begun trial fabrication of experimental liquefied hydrogen tanks, and preliminary and experimental researches on types and materials for feed pumps. Fiscal 1978 has moved forward improvements in prototype tank performance (heat insulation method to reduce evaporation loss), trial fabrication of liquid level meters, trial fabrication of feed pumps (especially selection of materials for the sliding parts), and researches on flow rate control methods. Drawings for modification and experiment of the liquefied hydrogen tanks were prepared, and the promising candidates were selected for material combination in pump sliding parts. Durability tests are continuing thereon. Flow rate control was also discussed. (NEDO)

Out of the developments of high efficient boilers which have been continued since fiscal 1993, the paper reported the result of the development conducted in fiscal 1996. The oxygen combustion (the oxygen enrichment combustion including 100% oxygen combustion) decreases the amount of flue gas and reduces heat loss of the flue gas, and is also effective as NOx reduction measures. The experiment was conducted using testing furnace. The boiler efficiency rapidly increased with the increasing concentration of oxygen enrichment. In the pure oxygen combustion, the overall boiler efficiency of a 106% level (low heating value standard) is expected. Since the boiler wet flue gas is decreased, the NOx emission is reduced. The boiler can raise the combustion temperature with no fear of NOx and can be reduced in size. CO2 decreases in proportion to the energy saving effect. The development of a condensation flue gas heat exchanger is aimed at recovering heat down to the low temperature. Prediction of heat transfer in the steam condensation region becomes possible, and the size reduction can be expected. Dew point corrosion resistant materials were also selected. As to the high speed combustion control, a simple type using micro-processor was developed. Obtained were high speed, compactness, electric power saving, and high controllability. 14 refs., 306 figs., 88 tabs.

So as to determine the energy distribution of defect level density in a-Si, which is indispensable for an optimum solar cell design, the hitherto unclear theoretical relationship between the field effect method and MOS (metal oxide semiconductor) capacity method is made clear, and a unified theory is newly established. A high-speed totally automatic evaluation system is developed, capable of high-accuracy determination of defect levels. For the realization of an a-Si MOS structure required for fulfilling the above purpose, a-Si is grown and then diborane and ammonia are subjected to a glow discharge decomposition process for the formation of a new insulation film. It is found that the material may be utilized for MOS structure construction for defect density evaluation. Studies are conducted on plasma emission spectroscopy and infrared absorption analysis for the elucidation of growth mechanism for the growth of high-quality a-Si.

This report covers part of the efforts to develop new hydrogen production technologies. Out of many processes involving Cu-halogen and alkali carbonate-iodine systems proposed as novel thermochemical processes, after they are compared with each other, a process of a sodium carbonate-iodine system with nickel in between is chosen. The chosen process is deemed to be the most excellent among the processes disclosed up to fiscal 1975. A feasibility study is conducted for the chosen process from the viewpoint of reaction rate, separation of reactive substances from each other, method for reaction manipulation, materials for device constitution, and thermal efficiency. As for the measurement of reaction rate for each unit reaction, basic reaction data are determined centering about the nickel iodide decomposition reaction and the sodium iodide carbonation reaction, and then reaction conditions which are roughly satisfying are obtained. A larger reaction unit is built in which the amounts of substances that come into reaction are approximately 10 times larger than those in the ones used in basic experiments. The progress of reactions is observed in the reaction unit, with the size enlarged in preparation for future construction of still larger reaction units. Methods for selectively isolating hydrogen out of gases ensuing from the decomposition are evaluated from the viewpoint of energy efficiency. In the selection of a reaction manipulation method, a single unit reaction process is advocated, and its thermal efficiency is estimated. (NEDO)

This R and D program is aimed at optimization of superconductors for improved levitation force of the superconducting magnetic bearings which support a 10 MWh power storage system by high-temperature superconducting flywheel (FW), to clarify possibility of sizing up the FW body and R and D themes for the commercialization. The processes are screened to simultaneously solve the conflicting targets of sizing up the sample of the Y-based bulk superconducting material and improved crystal orientation of the whole bearing, leading to selection of multi-seeding. The sample made on a trial basis improves levitation force by approximately 30%. It is considered that the OCMG-processed rare-earth-based superconducting material can generate very strong electromagnetic force, when combined with a permanent magnet. The Ag-doped Sm-based bulk material shows a reduced creep-caused loss of loading force, and a lower loss of Jc resulting from increased temperature than the Y-based one, decreasing AC loss and controlling temperature rise. The running characteristics and mechanical strength of the FW, and causes for temporal changes are investigated, in order to evaluate the superconducting material characteristics. (NEDO)

For every solar energy utilization field, its background, feasibility, impact in practical use, and R and D policy in Japan were studied. Heating and hot water supply by solar energy are already practical because of less technical problems and reasonable profitability, and cooling is also practical as far as a technical viewpoint. At present, the technical level of solar heat power generation is in the stage of basic technology, however, in the future, development of economically reasonable systems will be demanded as well as establishment of its technology. The most difficult problem for realizing practical solar cell power generation systems is cost reduction. It is also another problem that a big demand of Si for solar cells further exceeds the current yield of Si in a semiconductor industry. A small-scale hybrid solar cell power generation system applicable to the roof of general residences is already feasible. Although a solar furnace is still poor in application to industrial fields, it is expected as the leading part for a future solar heat chemical industry. (NEDO)

With the purpose of preventing increase in the number of bedridden elderly people, R and D was conducted on equipment for preventing degeneration of walking ability of long bedridden people and a safety device for walking exercise machines, for which the fiscal 2000 results were reported. In the development of the preventive equipment for the degeneration of walking ability, a chain type foot-operated exerciser was experimentally manufactured this year, with test and improvement carried out for the operating characteristics. The test result showed that this exerciser proved to be the equipment as originally intended in the prevention of lumbago, muscle/joint degeneration, etc.. The machine was also found effective for peripheral blood circulation. In the development of the safety device for walking exercise machines, clinical trial tests were conducted on falling and collapsing simulations. The result elucidated that, when a walking exercise machine stopped, a force imparted to the handle by a patient was intensified if the patient had paralysis of one side of the body and that, however, a preventive device installed adjustably to the patient's height was effective against falling. Further, as to collapsing, it was confirmed that, by setting the machine to stop by receiving a load of 20% or more of the body weight, the machine stopped concurrently with the collapsing of the patient.

With an objective to prevent increase of bedridden elderly people, research and development has been performed on a device to prevent retrogression of walking strength in long-term bedridden people, and on the safety device for a walking training machine. This paper summarizes the achievements in fiscal 1999. In developing the device to prevent retrogression of walking strength, a stepping exercising device was fabricated on a trial basis for two types, a hydraulic type and a timing belt type. Operation experiments were carried out. The hydraulic type device has flexibility when making stepping motions, gives good feeling, and operates smoothly. However, it is difficult to achieve the target values for the weight of 70N and the height of 600 mm. The timing belt type device allows reduction in size and weight, but would not operate smoothly if the brake is applied, requiring improvements in various points. In the research and development of the safety device for a walking training machine, discussions were given on a sensing method for the two typical patterns of a patient falling or tumbling down. As a result, a method was discovered, which has a possibility of identifying to some extent how the falling or tumbling is occurring. The existing walking training machines were modified by adding computers and sensors. (NEDO)

The current most important solar energy utilization fields are solar energy power generation (solar heat and photovoltaic power generation), and solar heat cooling and heating. A solar heat power system collects or stores solar thermal energy as energy source of power systems, and converts it to electric power through heat exchange systems. To establish such system, not only R and D on a collector, absorption capsule, storage unit and heat transfer unit, but also complete study on an optimum system configuration and environmental impact are necessary. A photovoltaic power system converts solar energy to electric power directly by photoelectric conversion device such solar cell. Except specific local uses, drastic cost reduction and improvement of a conversion efficiency (at present 12-15%) and life (several years) are necessary for solar cells. Although a lot of solar heat cooling and heating systems is in practical use in Japan, for its further diffusion an important research task is development of heat collector excellent in efficiency, cost, life and maintainability.

R and D was conducted on a 'system for monitoring living situation of elderly people' for the purpose of supporting the elderly living alone, with the fiscal 2000 results reported. In the development of a knowledge engineering system, a system was developed estimating the present position of an elderly person in his home or calculating his daily living activities, by analyzing data measured by infrared sensors, and thereby automatically inferring his behavior or health condition. In the research for practicability of the system, infrared sensors and sensors for detecting opening/closing of a door were improved, which included improvement by using telephone lines for example. In the demonstrative experiment, data were obtained which seemed to show a change for the worse of a disability condition due to senile dementia, or else, which appeared to be an inability to move occurring finally as a result of gradual deterioration of health. Another data measured disclosed that elderly people, unlike a normal life pattern, were living in a state with night and day reversed. From these results, the system can safely be said to have a function for monitoring the lives of the elderly people in point of their mind and body. (NEDO)

Studies were made for developing low-pollution easy-to-operate industrial furnaces for use in small and medium size plants in Indonesia. In this fiscal year, two kinds were selected out of Indonesia yielded brown coals, which were then subjected to test combustion in a bench scale fluidized bed combustor for examination for their combustion characteristics and environmental impact generating characteristics. The nitrogen oxides from the brown coals were found to mark approximately 100 ppm at an excess air ratio of 1.4, which was higher than in the case of bituminous coal. The NOx concentration level was found to be lower in the circulation fluidized bed boiler than in the spreader stoker fired boiler. Combustion efficiency exceeding 98% was achieved. A survey was conducted of brown coal users in various industrial fields in Indonesia. It was then concluded that the tested method not be recommended for use in small businesses in the textile industry because there would be no economic profit or improved efficiency for them but that it would be feasible in the plantation industry where the fluidized bed combustion/heat exchanger aided indirect process and the use of electrical dust precipitators would protect products from contamination.

A simplified method is developed, which measures dioxins in flue gas without using GC/MS (gas chromatography/mass spectrometry) of the double focusing type. The sampling device is built of two collecting bottles, containing water and diethylene glycol, and uses no XAD-2 (cross-linked amberlight divinyl benzene) resin. Such a design does not need time consuming Soxlet extraction in the sampling process and shortens the processing time. An HPLC (high performance liquid chromatography) system replaces the convenient column chromatography system in the cleanup process, and this enables automation and rapid treatment. For the measurement of toxicity equivalent, GC/MS is used to separate and quantify 17 kinds of toxic isomers as in the conventional method. The GC/MS is of the quadruple focusing type, however, and this reduces the device cost at the initial stage and shortens the time for operators to acquire the skills of maintenance and operation. Though the quadruple focusing type is inferior to the double focusing type in sensitivity, the shortcoming is compensated for by massive specimen injection using a PTV (programmable temperature vaporizer). The result of a JIS (Japanese Industrial Standard) method and the result of this newly developed method are found to agree excellently with each other. This method is simple and efficient, suitable for use in the analysis of small incinerator flue gas. (NEDO)

The trend of the technology development in the Japanese iron/steel industry was compared with those in foreign countries and surveyed to increase the international competitive strength. From the viewpoints of technology, industry and goods, the iron/steel field was characterized based on the statistic data, and especially automobile use steel materials were selected such as cold rolling high tension steel sheet, surface treated steel sheet, and bearing sheet. The analysis of factors of competitive superiority was conducted, and the following were presented: measures for process continuation, and measures taken from the age of equipment and cost indexes. The paper also surveyed the trend of pig iron making/steel making technology in Asia. The present international technical competitiveness in the iron/steel industry in Japan, especially of automobile use steel sheet, is very high. This is because of the well-functioned demand-oriented development, and also as a result of the mutually influentially conducted equipment development such as process continuation and development of new goods, supposing the iron/steel continuous process and reduction in impurities. However, fears are the stagnation in the recent technical development strength and the saturation of new equipment. Moreover, the further heightening is needed of the international cost competitive strength of general-purpose products. (NEDO)

In an a-Si{sub 1-x}Ge{sub x}:H film formed by decomposition in a glow discharge, since Ge-H is weaker than Si-H in terms of bonding, an increase in the amount of Ge decreases the amount of H and increases the number of Ge dangling bonds (DBs). Actually, however, H bonded to Si also decreases the number of DBs in Ge. This suggests that H is not working only to terminate DBs but that it also decreases the number of DBs through its structure-softening effect. In the case of a-Si{sub 1-x}C{sub x}:H, an increase in C results in an increase in H and in the number of DBs in both Si and C, this because C-H is stronger than Si-H in terms of bonding. F in a film is quite mobile. SiF and SiH in presence as distributed are found to decrease the number of DBs. Concerning the effect of hydrogen plasma processing for a-Si formed by thermolysis (CVD: chemical vapor deposition), the light transmission rate, absorption, ESR (electro-spin resonance) process time, and dependency on film thickness are investigated, and the relationship is examined between the defect-reducing effect of the H taken into the film and the transmission of light. It is found, as the result of experiments by a simplified molecular orbital method, that DBs stay in existence keeping away from where H or F is in presence. (NEDO)

This report summarizes the fiscal 1974 research result on the solar heat power generation system with a tower light collection system. This system receives solar radiation energy by reflector group, and concentrates solar energy reflected by each reflector on the heat absorber mounted on the top of the tower. A ratio of the whole reflector group area to the receiving area of the heat absorber is called a concentration factor. The heat absorber converts concentrated dense radiation energy to thermal energy, and transfers heated thermal medium to the bottom of the tower to supply solar heat to a thermal plant after appropriate treatment. Based on the above basic idea, study was made on the total system and each subsystem, and some problems on component equipment and materials were extracted. After solving these problems and improving the whole system accuracy, these results are put to practical use for design and operation of an actual pilot plant. The main research items are as follows: feasibility study, simulation, element study, preparation of a 10kWT test equipment, and planning of a 1,000kW class pilot plant. (NEDO)

This paper describes achievements in fiscal 1979 in research on aqueous alkaline solution electrolyte fuel cells. Trial fabrication and tests for an oxygen electrode were performed on a catalytic electrode added with silver using carbonblack and graphites as carriers having excellent corrosion resistance and large surface area. Characteristics not inferior to electrodes using activated carbon as a carrier were obtained in both of the initial characteristics and continuous discharge characteristics. A platinum added electrode also showed the same performance as the silver added electrode. A hydrogen electrode containing Zr and iron among those containing Raney-Ni was found to have high oxidation resistance and stability in terms of life. A platinum added electrode using graphite as a carrier provided satisfactory initial characteristics as a hydrogen electrode. Research on a single cell construction has used and tested eight-cell laminated cells with an area of 1,000 cm{sup 2} using bipolar sheets made of carbon. The test verified appropriate the removal of produced water and heat using mainly the hydrogen circulation, which has been discussed in the summary design.

As for the formation of amorphous semiconductors by photo-CVD (chemical vapor deposition) processes, details are examined of a-Si formed by the excimer laser-excited photo-CVD process, a-SiC formed by the directly excited photo-CVD process, a-SiGe formed by the mercury sensitized reaction photo-CVD process, and {mu}c-Si formed by the mercury-sensitized reaction photo-CVD process. It is then found that all of the said materials are superior to a product of the plasma CVD process in terms of film quality. As for the fabrication of amorphous Si solar cells by a photo-CVD process, a 3-separate-chamber unit is built, in which all the p-, I-, and n-layer are formed by photo-CVD. It is then found that the introduction of a buffer layer into the p/I interface is a powerful tool to enhance efficiency and that the use of the buffer zone brings about an increase of 9% or more in conversion efficiency. In the case of an amorphous solar cell using monosilane, buffer layer introduction results in a conversion efficiency of 9.05%. (NEDO)

This paper describes the surveys in fiscal 1978 on the status of progress in research and development in the Sunshine Project. Identification, evaluation and analysis were given on the status of progress in research and development and developed technologies in each project. Items of information were provided to related organizations for the purpose of mutual information exchange. The subjects include solar heat power generation, solar beam power generation, solar energy air conditioning, hot water supply systems, geothermal applications, and coals. Project teams were organized to discuss more precise identification of the current status of research and development, and increase in efficiency of the research activities. Since the Sunshine Project (which had begun in 1974) is coming close to completing the interim programs in the first term in fiscal 1980, it is thought necessary to provide assistance such as provision of items of information both for each group and on the collective basis. The basic issues at the end of the first term include presentation of the second term conception to the persons responsible of the program management, clarification of the evaluation criteria, strengthening of horizontal communication and adjustment functions in general, and feeding back of the surveys on the status of progress. Putting the basic problems in individual projects into order indicates necessity of discussion on the voucher control system, procedures of disposing of facilities after the related researches have been completed, issues of creating initial market, and expansion of technological discussions.

This report describes the fiscal 1976 research result on Si ribbon crystal vertical pulling method for photovoltaic power generation systems. The equipment for simultaneous growth of 3 ribbon crystals was designed and prepared in consideration of capillary die arrangement, vertical pulling method and control method of temperature profiles on the die surface. The temperature profiles on the die surface were controlled by subheaters for 3 parts of each capillary die which were divided longitudinally. Ribbon crystals grew up to 5mm simultaneously through both end dies. By cooling a part of crystal, fast pulling is probably possible. Study was made on the correlation between various crystal defects of Si ribbon crystals and cell characteristics, and in particular, basic characteristics of SiC deposited particles by SEM observation to reduce their impacts. Possibility of simultaneous vertical pulling of crystals was verified by using a capillary carbon die for multi-pulling. Although crystals grew by eutectic reaction under saturated dissolution of carbon, crystals with no transition were obtained. An SiC-coated die was excellent rather than carbon one. (NEDO)

In fiscal 1974, the domestic and overseas developmental states of fuel cell bodies were surveyed, and some problems on the interconnection between a fuel cell system and power system were studied. Since the maximum outputs of conventional fuel cells are only nearly 10kW, however, those from several hundreds kW to several ten thousands kW are required for buildings or commercial power facilities, in the fiscal 1975, some supposed problems derived from such scale- up of fuel cells were extracted to study their solutions. Study was made on 4 kinds of fuel cells such as alkaline electrolyte, acidic electrolyte, molten salt electrolyte and solid electrolyte fuel cells, and fuel modifier for generating hydrogen. As preliminary modeling work for dynamic performance analysis of fuel cell systems, study was made on scale of the model, DC devices and equipment for customers, environmental impact, power supply reliability, various characteristics and problems in load variation including start and stop, and kinds of accidents and their measures.

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 study aims to present the psychometric properties of the Portuguese version of the Positive Valuation of Life Scale (Lawton et al. in J Aging Ment Healt 13:3-31, 2001). Sample included 207 community-dwelling elders (129 women; M Age = 77.2 years, SD = 7.5). The data collection included the translated and adapted Portuguese version of Positive Valuation of Life Scale, Life Satisfaction Index Z, Meaning in Life Questionnaire and Geriatric Depression Scale. From exploratory factor analysis, two factors emerged, existential beliefs and perceived control, explaining 49 % of the total variance. Both factors were positively related with meaning in life and life satisfaction and negatively related with depression (p 0.75). The Portuguese version of Positive VOL Scale represents a reliable and valid measure to capture the subjective experience of attachment to one's life. The two-factor structure is an update to Lawton's previous work and in line with findings obtained in the USA (Dennis et al. in What is valuation of life for frail community-dwelling older adults: factor structure and criterion validity of the VOL, Thomas Jefferson University, Center for Applied Research on Aging and Health Research, 2005) and Japan (Nakagawa et al. in Shinrigaku Kenkyu 84:37-46, 2013). Future research is required to investigate VOL predictors and the potential changes toward the end of the life span.

The purpose of this research is to grasp the policy of the oil sand resource countries, the properties and existing conditions of the resources, effects of the oil sand resources on a long term energy supply/demand, etc., and to clarify the meaning and position of the researches on the development of oil sand resources in the future energy policy of Japan. The quantities of oil sand resources are mostly in the process of investigation except Alberta province of Canada and are estimated to be two trillion barrels. The quantity for which strip mining is possible is about 90 billion barrels, which are mostly located in the Athabasca region. The oil sand holding countries take a policy of positively developing oil sand. No barriers are particularly provided against the introduction of foreign technology and capital. Where the prospects are possible for the development of oil sand are Canada and Venezuela. R and D should be emphasized on the refining of bitumen and the extraction method within the oil reservoir. The investment per b/d is about 15-20 thousand dollars, which is likely to be more than twice as much as for the North Sea oilfields. The properties and quality of the synthetic crude oil are superior while the risk of exploitation is small; therefore, oil sand will be competitive with crude oil in the future. (NEDO)

The chlorine from the electrolysis and Si as material comes into reaction in a salination furnace for the generation of silicon tetrachloride to be supplied to the process. Minor tests are made involving pressure control, distance between the electrodes and the effect of the diaphragm, stirring in the hydrogenation chamber, dust in the monosilane generation chamber, and the insulation of the cathode lead rod, and the results are reflected on the process of experimental unit designing and building. The unit has harm neutralizing facilities for safety assurance because much hydrogen and a little chloride are consumed while the unit is in operation, with some silicon tetrachloride to be retained in the unit. An infrared absorption method is used to analyze impurities in the monosilane gas, when the method exhibits a capability of detecting 2ppm of methane. (NEDO)

A polygonal mirror in a printer and the main shaft of a high-speed milling machine are used as models for the development of technology for applying C/C (carbon/carbon) composite materials to machine components that are required to turn at high speeds. Various C/C composites are tested for flexural strength and thermal expansion for the designing and manufacturing of C/C composites for the polygonal mirror and main shaft. The first coating on the C/C composite is deposited by laser/plasma hybrid spraying, and is a Mo coating. A spraying robot is experimentally built for homogeneous coating. In the case of polygonal mirror, an Al coating is deposited further by the gas-deposition method. The polygonal mirror proves excellent in both dimension and reflectance, and attains the target speed of 45,000rpm. In the case of milling machine main shaft, however, it is not strong enough to withstand 40,000rpm although it is a success from a viewpoint of coating technology and manufacturing technology. 15 refs., 33 figs., 13 tabs.

This report describes the fiscal 1974 research result on metal system materials for solar cooling/heating and hot water supply systems. Study was made on cathodic protection of a roll bond heat collection board promising as Al plane collector. The protection is dependent on sacrificial anode materials. Al-Zn system alloy including minute amounts of In and Sn was effective in protection by transferring natural electrode potential to a base side largely, however, excess addition of In and Sn increased self-corrosion, remaining some issues to be solved. The prototype water flow corrosion test equipment was prepared for corrosion analysis of an Al roll bond collector natural circulation hot water supplier. Preliminary study was made to give selective absorption power (large short-wave absorption and small long-wave radiation from collector surfaces) to a collector. Deposition of Cu, Ni, Co and Sn oxides as black semiconductors into Al anodic oxidation film porous layers by secondary electrolysis was invalid as well as a painting method. Glossy Ni plating onto Al and black Cr and Ni plating onto the surface more elevated solar exposure surface temperature by more than 20% than black painting. (NEDO)

For the establishment of a low-temperature formation technology for compound semiconductor polycrystalline thin film of CuInSe{sub 2}, research is conducted involving film formation and film quality evaluation using the ICB (ion cluster beam) method. In the research on the film formation, an In-excessive film is placed on a Cu-excessive CuInSe{sub 2} film using the ICB method for the formation of a two-layer film. Bulk CuInSe{sub 2} and thin-film polycrystalline CuInSe{sub 2} are evaluated using PL (photoluminescence) spectrums excited by YAG (yttrium aluminum garnet) and Ar. In both bulk and thin film, it is suspected that clues are latent in the levels deeper than hitherto reported. A luminescent belt of 0.75eV is detected. Changes in film quality before and after oxygen annealing are verified using the YAG-excited and Ar-excited PL spectrums, and the result suggests the feasibility of tracking the process in which the effect of annealing propagates inward from the interfacial surface. Fe-added single-crystal CuInSe{sub 2} is investigated for the optical and photoelectrical effects of Fe impurities. (NEDO)

For the purpose of developing a new hydrogen production technology, a feasibility study was made of the copper-halogen system and alkali carbonate-iodine system processes presented as a new thermochemical process from viewpoints of the progress of reaction, side reaction, reaction yield, thermal efficiency, etc. The study went forward smoothly, has achieved the target in the early stage, and has been finished. In the study of optimal conditions of the process, the progress of each unit reaction was experimentally confirmed. By measuring the reaction yield, optimal reaction conditions for expediting the reaction were found out. As a result, it was found that the proposed processes proposed both advance rather easily, and was thought that those are worthy of making further engineering study. In the study of improvement and optimization of the process, since some altered processes are considered for the processes presented, an investigational study was made on a method to calculate thermal efficiency which is one of the standards for the process evaluation, and thermal efficiencies in various processes were trially calculated, based on the calculating method.

This report describes the fiscal 1974 research result on glass system materials of plane collectors for solar cooling/heating. A barrel lens type collector was poorer in efficiency than conventional ones. A one-directional Fresnel lens type one was promising for improvement of solar radiation collection. The prototype In{sub 2}O{sub 3} selective transmission cover glass was prepared by vacuum deposition. Although selective characteristics including a solar transmissivity of 74% and an IR reflectance of 75-80% were obtained, further improvement of more than 10% is necessary. The evaluation results of some collectors are as follows. A vacuum type is poor because of its low efficiency and necessary vacuum sealing. A multi-layer type shows unsatisfactory performance at some temperatures. A glass honeycomb type is most likely because of its uppermost collection efficiency, however, development of production technology of heat-resistant honeycombs and its profitability remain to be solved. A deformed multi-layer type is practical because of its high efficiency, simple structure and low cost. Further improvement of the transmissivity and IR reflectance of cover glass by more than 10% is necessary. (NEDO)

Element technologies were developed for the manufacture of superconducting magnetic bearing (SMB) with the purpose of putting to practical use a 10 MWh class high-temperature superconducting flywheel power storage system. This paper explains the fiscal 1997 results. A {phi} 180 radial type SMB was designed and fabricated that satisfied the rotational strength at 17,200 rpm for a medium-sized model for measuring characteristics. Compared with the bearing made in the preceding year, improvements in the bearing dynamics were contrived such as flux creep, load capacity and rotational loss, with the maximum flux density improved by 30%; however, only a few percent improvement was attained in field uniformity. An SMB characteristics measuring and testing machine was built, with the characteristics measured. It was confirmed that the rotational loss of a control type magnetic bearing and the intrinsic performance of the testing machine were unchanged regardless of the operation/non-operation of the radial type SMB. The characteristics of the {phi} 180 axial bearing were measured by a stationary type bearing constant testing machine made in 1995, which provided a load capacity characteristics curve with the initially set gap as a parameter as well as a minor loop curve and a load capacity. Also obtained were the maximum average bearing pressure and the maximum load capacity. (NEDO)

The amorphous solar cell interface has been under study for the enhancement of efficiency and reliability in amorphous solar cells, and this is the compilation of the results achieved in fiscal 1991. In the effort to enhance delta-doped amorphous silicon solar cell efficiency, an amorphous Si solar cell is built using a ZnO film as the transparent conductive film. As the result, an a-Si solar cell with a conversion efficiency of 11.5% is obtained. In the research on the suppression of photodegradation in a-Si, from the viewpoint that a reduction in the amount of hydrogen contained excessively in the film will be effective in decelerating photodegradation, a photoexcited hydrogen radical treatment method is newly proposed, and basic studies are conducted on it. As the result, it is found that an a-Si film processed by a 20-second hydrogen treatment at a substrate temperature of 460 degrees C exhibits a lower photodegradation rate than an ordinary a-Si film. In the research on the deposition of amorphous Si film, a VHF frequency is used instead of 13.56MHz for plasma, and an amorphous Si film is deposited efficiently at a lower voltage at which ions cause less damage.

The following technologies were developed for the purpose of materializing various methods of a solar cooling/heating and hot-water supply system using aluminum and other metallic materials: (1) research on improving corrosion resistance of metallic materials for a heat collector plate and (2) research on a selective absorbing film. The results in fiscal 1979 were as follows. (1) A practicality running test for a solar panel, which started in fiscal 1977, was continuously carried out at eight places in the nation. After approximately two years and a half passed, each panel was cut open and analyzed. As a result, despite a difference in the degree of corrosion by the regions, an Al-Zn-Fe-In alloy had a larger corrosion area than two other alloys, but the corrosion depth was shallower, with the corrosion remained only in the clad layer, which seemed to eliminate the fear that it might grow to be a through-hole for the time being. This research was completed. (2) Research for the selective absorbing film was carried out in fiscal 1979 on a chrome black membrane by a high frequency excited ion plating method and on a carbide and nitride membranes. In addition, a durability test and an Auger analysis were performed for a titanium nitride selective absorbing film that was obtained by a DC bipolar reactive ion plating method. (NEDO)

In this research on a hydrogen energy total system, studies are conducted on the plan of a hydrogen energy proving pilot base and on hydrogen as fuel for automobiles. It is estimated that the construction of a hydrogen energy proving pilot base will cost 7.125-billion yen in total. The sum includes 6.410-billion yen for the construction of a system on an island named Island A, 500-million yen for structures on an island named Island B, and 215-million yen for the construction of a marine transportation system between the two islands. Large shares will go to a hydroelectric power plant and a hydrogen liquefaction system, the two occupying approximately half of the total sum. In the study of hydrogen as fuel for automobiles, it is concluded that hydrogen is advantageously employed as fuel for automobiles. When comparison is made in terms of heat value, it is found that even a hydrogen engine which is a mere modification of a currently used engine is comparable to the currently used engine in terms of performance. As for abnormal combustion, a hydrogen/air 2-system injection method is contrived, and this solves the problem almost completely. Cryogenic hydrogen is advantageous in both NOx emission and heat efficiency though within certain limitations. From the viewpoint of safety, the recommended automobile fuel structural formula is GH{sub 2}(MH). (NEDO)

This paper explains basic studies on characteristics of coal char gasification under pressure. Hydro-gasification of coal needs as a gasifying agent a large amount of hydrogen, which is effectively produced by the water gasification of exhaust unreacted residual char. In fiscal 1975, gasification was tested on Taiheiyo coal carbonized char by an atmospheric fluidized gasifier of 28 mm bore. In fiscal 1976, experiment was conducted under pressure by fully improving the auxiliary safety equipment. The char and gas yield increased with higher pressure in pressurized carbonization by an autoclave. In fiscal 1977, clinker was successfully prevented by using quartz sand for a fluidized medium. In fiscal 1978, two-stage continuous gasification was examined.

1993-10-01

This paper describes the research achievements in the Sunshine Project in fiscal 1992 in studies on a direct gasification catalyst. The paper summarizes the points where the catalyst research has reached to date. The catalyst surface effective for hydrogenation is the metal surface that can dissociate hydrogen. However, metals having large adsorption heat against hydrogen do not show the activity greatly because these metals are difficult of desorbing hydrogen having high dissociating activity. The coal liquefaction system has the surface oxidized by water content, wherein hydrogen dissociation cannot be expected, and sulfides are suitable. When a sulfide catalyst contacts hydrogen, the catalyst itself is desulfurized, producing H{sub 2}S and becomes a low-order sulfide. When atmospheric H{sub 2}S contacts this sulfide, it dissociates into HS and H, and this H behaves as active hydrogen. However, the liquefaction activity can be recognized even in a sulfuric acid type catalyst containing no sulfide whatsoever, wherein the H{sub 2}S partial pressure in the reaction system becomes extremely low. This fact means that the active hydrogen is not necessarily generated by the dissociation of H{sub 2}S. There is no other way but to think that hydrogen is dissociated directly without going through H{sub 2}S. If this is true, it provides a new guideline in developing and designing the future catalysts. (NEDO)

The pressurized hydro-fluidized gasification method is such that coal is hydro-gasified under a pressure of 30kg/cm{sup 3} to produce a methane-rich calorie gas. This method is a combination of three independent processes, namely, (1) thermal cracking of coal, (2) hydrogasification of thermally decomposed product, and (3) water gasification for self-contained hydrogen, and is a continuous gasification method in which all processes are operated in a fluidized bed. In fiscal 1976, an operation technique was found in which conditions suitable for each reaction purpose were given to a detached thermal cracking furnace and hydrogasification furnace and in which continuous gasification was still maintained without an adverse effect between the two furnaces. This year, the continuous gasification test will be implemented successively, determining suitable operating conditions for the purpose of increasing methane concentration and improving gasification efficiency, and concurrently extracting device-related problems that impair the continuous operation. With the aim of obtaining a self-contained system for hydrogen, water gasification tests will be conducted, with the optimum conditions determined for the water gasification. An operation test will be carried out for an internal heat type control box, so that the functions under pressurization, durability and operation criteria will be determined. (NEDO)

For the development of high-efficiency, large-area, long-life, and low-cost solar cells, research is conducted on new methods of film formation and defect evaluation. Concerning the kinetics of Si thin film, a radical beam deposition method is proposed as a new low-temperature thin film growth method. Using the new method, a {mu}c-Si film is manufactured, through only a purely radical substrate surface reaction of chemically active, electrically neutral excited species. In research on the amorphous semiconductor superlattice, a new study is conducted on a multilayer, cyclic-structure superlattice consisting of thin films of a-Si:H and a-Si{sub 1-x}N{sub x}:H. In the research on an a-Si:H film formed by the direct photo-CVD (chemical vapor deposition) of disilane, the unit is improved and B and P are successfully doped by means of decompressed photo-CVD. In the evaluation of new materials for solar cells, research is conducted on the after-annealing characteristics of a-Si:H grown at a high speed, electrical characteristics of post-hydrogenated low boron-doped CVD a-Si, and microcrystalline SiGe alloys made by the spattering plasma CVD method.

In the basic studies of large-area a-Si film formation technologies, the validity is discussed of the evaluation technique using plasma optical emissions spectrometry (OES) employed for the achievement of the intended film qualities. The film forming condition that exerts the greatest influence on the plasma state relative to OES is the power of discharge, and correlations are found to exist between specific emission intensity, infrared absorption level, and photoconductivity of the film. It is found that a P- or B-doped Si:H/SiC:H film is suitable as the material for the window layer on the light-receiving surface of the solar cell. Materials are studied for the i-layer responsible for photo carrier generation, isolation, and acceleration. Studies are also conducted on fluorine-containing film. In the efforts at designing and building solar cells, ITO (indium-tin oxide)/n-i-p/SS (reversed type) cells are analyzed, designing is carried out for transparent electrode film thickness optimization, window effect in stainless substrate cells is improved, glass substrate cells are experimentally built and analyzed, large-area solar cell properties are improved, interaction between the substrate and a-Si is studied, and reliability tests are conducted. For cost reduction, it is necessary to develop technologies of automated production of simplified-structure modules using low-cost materials. Basic matters are taken up for discussion. (NEDO)

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

The reaction velocity constant of coal or the distribution of products in a high-pressure hydrocracking process of coal are found not to be affected by the temperature rise rate. The liquefaction of coal using CO and water is analyzed using a high-pressure differential thermal analyzer. The hydrogen gas generated during the water gas reaction reacts with CO for the formation of alcohols, carbonic acid, etc. The reaction rate is found to be higher when the specimen contains more oxygen. When coals greatly different from each other in terms of thermolytic reactivity, caking property, and intersolubility with medium oils are mixed, synergistic effects are exhibited, positive when active hydrogen supply is abundant and negative when it is short. In the case of the Hokkaido coal which contains 73.0-87.4% carbon, the grain diameter does not affect the liquefaction rate when the coal is crushed to the 48-mesh size approximately. Reaction velocity in direct liquefaction does not relate to hydrogen pressure. Asphaltenes in coal liquefaction are produced at the beginning of reaction, to be reduced in molecular weight due to cleavage of methylene crosslinks with the progress of reaction. Studies are conducted in a 0.1t/d-capable bench plant about liquefaction reaction characteristics and coal liquid properties, and chemical structures. (NEDO)

Regarding the Sunshine Project, this paper describes characteristics and technologies of hydrogen combustion, problems in developing combustion devices and conceptual design thereof, catalytic combustion, hydrogen energy systems, and economic evaluation on hydrogen fuel as a heating energy. Hydrogen combustion could emit small amount of NOx if it is sufficiently pre-mixed with air, but at the same time could cause reverse ignition very easily making its practical use difficult. Abolishing the air pre-mixture would cause no fear of reverse ignition, but generate much more NOx than from hydrocarbon fuels. Even if attempting to apply conventional methods such as two-stage combustion, partial stack gas recirculation, water addition, and lean burn systems, many of them cannot be applied as they are, requiring research and development efforts. Discussions on hydrogen energy as a system included those on thermo-chemical hydrogen manufacturing using heat from high temperature gas reactors (using water as the raw material), and electrolytic hydrogen gas manufacturing utilizing surplus electric power from high speed breeder reactors. Whether these methods could be used in markets economically will depend on manufacturing efficiency and cost of hydrogen gas. As the economic evaluation on hydrogen as fuel, discussions and considerations were given on introduction priority in the industrial heating furnace field. (NEDO)

Patents related to the research under the Sunshine Program are surveyed so as to ensure that the program be promoted smoothly and efficiently. Since the scope of the hydrogen energy technology is extensive, branches supposed to be relatively important only are surveyed, which include the production of hydrogen (thermochemical process, photochemical process, and electrolysis), storage and transportation of hydrogen, safety of hydrogen, hydrogen fuel cells, hydrogen-fueled engines, and hydrogen combustion devices. The basic policy to follow in the extraction of necessary patents is that all related to the hydrogen energy technology be collected from as many fields as possible. However, it is impossible to read all the laid-open patents. Under such circumstances, out of the items in IPC (International Patent Classification) used by the Patent Agency, those deemed to be closely related to the hydrogen energy technology are designated and, when the classification item attached to the official gazette matches one of the IPC classification items, it is extracted as a desired item after deliberation of its relationship with the hydrogen energy technology.

A technology is developed to produce useful gases such as acetylene, hydrogen, and carbon monoxide from coal and coal-related substances making use of the high-temperature high-density energy of plasma jets. Using the newly developed systems, the energy utilization rate is 50% or higher and the yields are 60-100g/kWh for acetylene and 100-160l/kWh for hydrogen. For the achievement of the goal, two types of plasma gasification systems have been developed. One is a '100kW 3-torch plasma gasification system' in which the specimen for gasification is fed to the center of the combined flame for improvement on the contact rate between the specimen and plasma flame. The other is a 'rotating plasma torch system' in which the flame is rotated, and expanded, by an externally provided magnetic field for improvement on the contact rate between the specimen and plasma flame and, simultaneously, for an increase in energy utilization efficiency by feeding the specimen into the discharge region. In this fiscal year, quenching tests are conducted using water and oil so as to establish the difference in quenching effect between quenching agents. What to improve in the systems are clarified.

This report describes the fiscal 1976 research result on 2-6 group compound semiconductor solar cells for photovoltaic power generation systems. The research aims at the system less than 1/100 in cost. Vapor deposition resulted in failure to obtain high-efficiency cells. Vapor-phase growth revealed Cd-Te single-crystal solar cell is promising, however, resulted in failure to obtain high-efficiency thin film elements. Both chemical deposition and sintering succeeded in mass production of prototype high-efficiency elements equal in performance. However, since chemically deposited CdS film is too thin having higher serial resistance, it requires In{sub 2}O{sub 3} auxiliary transmissive electrodes on glass substrates. Since CdTe film and CdS film also require completely different vapor deposition processes in hetero- junction, chemical deposition is more disadvantageous in cost than sintering. CdTe thin film fabricated by screen printing/sintering is most promising. Since Cd is harmful to human bodies, study was made on pollution preventive measures in its production or use stage, and accidents or fires, obtaining some results. (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 also describes corrosion resistance tests under heat transferring condition by using pipe-formed test pieces. (NEDO)

The experiment result on discharge and diffusion of hydrogen gas from underground buried conduits and compressed hydrogen gas vessels, and the hydrodynamic study result on gas discharge are as follows. The discharge experiment from underground buried conduits showed that the amount of gas leakage increased with a discharge duration linearly, and increased with a pinhole diameter at a rate more than a cross section ratio. Its underground diffusivity is large, and hydrogen gas advances as spherical wave uniformly within a certain discharge velocity. Gas leakage on the ground surface is affected by not buoyancy but wind (air flow) strongly. The discharge experiment from compressed hydrogen gas vessels showed that the diffusion concentration profile of discharged gas can be explained by conventional diffusion equation. Variation in gas pressure in vessels due to gas discharge, and durations until the end of discharge agree with hydrodynamic data on the whole. Thrust and change in gas temperature due to gas discharge can be estimated theoretically by the same manner. (NEDO)

This report describes the fiscal 1974 R and D result on solar cooling/heating and hot water supply systems for apartment houses. In system analysis, the system plan was selected through basic data survey, modeling by combining some kinds of such systems and energy flow calculation. On solar heat collector, theoretical analysis was made on a stationary plane collector, and study was made on cover glass material and absorption surface performances. On Rankine's engine, studies on advanced selective absorption film, transmissive film, prevention of heat radiation and converging collector were necessary. As solar heat driving refrigerators, absorptive one and Rankine's one were promising. As heat media for refrigerators, R-11 and 113, and R-114 and 11 were suitable for turbo one and displacement one, respectively. Since a displacement compressor is featured by high-efficiency lower-speed operation than that of turbo one without any constraint, its direct connection with a motor or generator is possible. Screw compressor belonging to displacement one was promising. Rotary displacement one was also promising in a small-capacity range within 20-50RT. (NEDO)

Research has been carried out on various collector members using synthetic resins for a solar cooling/heating and hot-water supply system. In the research on a light selective transmitting film, a technology was established in which an In{sub 2}O{sub 3}/SnO{sub 2} film was processed on a polyester film at a spatter speed of 4,000 (angstrom)/min by using a conventional spattering device and a method of running the film while it was cooled. In the research on transparent heat insulating materials, a plastic heat insulator molding test device was used, molding and evaluating the straight groove type bent molded product of various plastic films, with the best results obtained using a polyester film. The selective absorbing film proved that the synthesizing time of Co{sub 3}O{sub 3} was reduced by about 30% and that no performance was lowered by the mixture of inexpensive metallic oxides, which enabled a prospect of the cost reduction. The base material for the heat collecting body was produced using a three-layer film containing a metallic foil and a water channel of a molded sheet structure by a heat joining method, but no improvement was seen in the pressure resistance. In the general evaluation of the practicality of a high performance collector, the selective transmitting film was found insufficient in the contributing effect to the improvement of heat collecting efficiency. The transparent heat insulating material contributed to the efficiency increase through the improvement of the light transmissivity. (NEDO)

This report describes the fiscal 1976 research result on solar cooling/heating and hot water supply systems for large buildings. Although the small experimental single/double effect absorption refrigerator system didn't satisfy the initial design specifications, if the large system is used, it probably satisfies them. Its wide operation range was confirmed by adding LiCl to water-LiBr system coolant. Concentration by reverse osmosis and electrodialysis for recycling absorbent resulted in failure. The storage tank volume of coolant and absorbent necessary for a heat storage refrigerator reached 4 times as large as refrigerator unit one. The primary basic plan of a single/double effect refrigerator system with plane collectors was prepared for Oita University. For system simulation, more practical characteristic equations are showed by reconsidering equations for single effect systems. The characteristic equations for double effect and single/double effect systems were obtained on the basis of the 1976 research result. The control method of hot water and absorbent effective for refrigerators was clarified. Absorbent circulation of 3.5-4% in concentration difference was optimum. (NEDO)

For realizing a high-performance amorphous solar cell, research is conducted on how to evaluate the amorphous silicon film formed by glow discharge decomposition as regards its optical and photoelectric characteristics, basic physical properties of its electronic states, and its film quality and film forming conditions. Research is conducted on the mechanism of glow discharge decomposition reaction using plasma spectroscopic techniques and on the conditions of film formation, when low-temperature SiO{sub 2} film growth is caused to occur by a directly excited photo-CVD (chemical vapor deposition) method in which a deuterium lamp and Xe lamp are the exciting light sources and SiH{sub 4} and O{sub 2} are the source gases. In research on the mechanism of photoelectric conversion in an a-Si film p-I-n junction system, a method is developed of evaluating physical property parameters in accordance with a field drift type photovoltaic effect model. In research on the evaluation of the optical properties of a-Si films using modulation spectroscopy and polarization analysis, electronic states in the vicinity of the a-Si based thin film band end is examined using an ER method which is one of the modulation spectrometric methods.

The basic physical properties of glow discharge-decomposed amorphous silicon film are studied. The performance of an a-Si p-i-n (amorphous silicon positive-intrinsic-negative) junction solar cell is found to be greatly affected by the binding of carriers along the p-i or i-n interface. A new concept is introduced, which is useful in the study of the photo-produced carrier collection process. The distance between the plasma excitation center and the substrate and the intensity of the electric field just above the substrate are changed systematically for the evaluation of film quality and for the study of film formation mechanism. It is found that plasma excitation as a mechanism of film deposition, the transportation of excited seeds to the substrate, and the incorporation of film constituting atoms into the film are important. A high-speed ion beam technique is used for the analysis of impurities. In the case of a-Si or a-SiC deposition by glow discharge decomposition, metallic Sn or In is deposited along the interface and diffused into the deposited film. The diffusion is closely related to the performance of solar cells, and a 2-layer structure incorporating the merits of both ITO (indium-tin oxide) and SnO{sub 2} films is found suitable for this purpose. Using an a-SiC:H/a-Si:H heterojunction solar cell, a conversion efficiency of 8.04% is achieved. (NEDO)

In the 1st research, the analysis result showed that deterioration under solar radiation or by short circuit is derived from an increase in resistance around a positive electrode and a decrease around a junction caused by change in Cu{sub 2}S composition due to migration of Cu ions in a Cu{sub 2}S layer by photo current. In the 2nd research, study was made on preventive technology of Cd pollution. In the 3rd research, basic study was made on the production systems of semiconductors such as sintering, chemical separating and vapor-phase growth for cost reduction. (NEDO)

An a-SiC (amorphous SiC) material with a wider band gap adds to the conventional hydrogen- and fluorine-based a-Si materials in the study for device efficiency enhancement, and the a-SiC is found suitable as a wide-gap window material. The separated formation technique is found to work effectively for improvement on cell characteristics because it prevents the mixing of impurities of different types. A p-i-n (positive-intrinsic-negative) type amorphous solar cell is subjected to analysis, and a theoretical efficiency of 12.5% is obtained in photoelectric conversion. A conversion efficiency not less than 7% is obtained from an ITO (indium-tin oxide)/p(SiC)-i-n/Al cell on a glass substrate. Design is optimized for area enlargement for an integrated type device, which results in an experimental 10cm-square integrated type solar cell with a conversion efficiency of not less than 5%. As for modularization, a glass substrate for integrated type device is used, as is, as a light-receiving surface protecting board, and studies are conducted thereon. It is then found that the amorphous solar cell experiences some degradation in reliability at the beginning of an irradiation test but that no extensive degradation in reliability is observed even after the passage of 1,000 hours from the beginning of the test. The separated formation technique is found suitable for use in mass production. (NEDO)

The purpose of this research is as follows: (1) For a vitreous selective absorbing film; establishment of large-plate processing conditions of a selective absorbing film using a black glass enamel layer, and setting of heat collector plate structure and estimation of its manufacturing cost, (2) For a high-performance collector; establishment of thin film honeycomb forming technology and estimation of its manufacturing cost. In examining the large-plate conditions, a processing test device was made for a vitreous selective absorbing film, a device capable of continuous glass enamel coating and SnO{sub 2} film spraying, which resulted the same {epsilon} characteristics as the two-step processing. Spraying conditions were established for two kinds of sizes of an iron base board. The glass enamel coating was examined using the spraying method, with the flawless result obtained. A tube-on-sheet method was employed as the heat collector plate structure of the vitreous selective absorbing film, obtaining a value of 147kcal/m(center dot)Hr(center dot)degree C. With the vitreous absorbing film processing applied on an iron base board, a heat collector plate of 1x2m was experimentally produced. Using this heat collector plate, a trial product was made for a multiple layer type collector, and the heat collecting efficiency ratio was measured, which was as predicted. The manufacturing cost of one heat collector plate is estimated as 13,000 yen in mass production (1,000 units/month). This research is complete. (NEDO)

Analysis was made on timing, patterns and scales of introducing hydrogen energy into the Japan's total energy system, and case studies were made on transfer of the comprehensive systems that can be realized in the years of 1985, 2000 and 2025. The basic conception for the analytic method employed a method to analyze and present theoretically the conditions in which prerequisites or results of the estimation can be established, rather than intending elucidation of the estimation itself. An energy model was used for the theoretical means thereof. The objective function to be optimized was assumed to maximize (estimate over the planned period of time) the total effectiveness of the hydrogen energy system converted into the present value being given appropriate discount. The economic performance measures for different secondary energies working as the comparison measures are the limiting production cost of each energy. A consideration was given to the point that the electrolytic hydrogen cannot compete with that made by using the thermo-chemical method (if developed successfully) using heat from high-temperature gas reactor if the fossil fuel price rises sharply. Considerations are also required in replaceability of hydrogen energy with other energies, and hydrogen utilization in petroleum refining. (NEDO)

For continuous ceramic fiber as a reinforcing material, the Si-Zr-C-O system was selected, and the chemical gas-phase impregnation process effective to enhance the fiber/matrix interface characteristics as the matrix forming method was used together with the inexpensive precursor polymer impregnating and sintering process. Investigations were performed on the advanced control functions to reduce fuel consumption as the development of CO2 emission suppressing technology, and on the trends in discrete control. In addition, the optimal engine control logic and the specifications for discrete system constituting devices to be evaluated as the prototype in the future were established. (NEDO)

R and D was conducted on a bio-functional material that is formed by synthesizing non-natural amino acids required for the manifestation of the function, incorporating the amino acids into new bio-functional peptides to be synthesized, and fixing the peptides on a substrate such as plastics. Activities were carried out in three areas, which were (1) innovative technologies for producing functional molecules, (2) R and D on materialization technologies of functional molecules: technique of pattern formation by photochemical reaction and of fixation, and technique of preparing peptide film using vacuum thin film forming technology, and (3) comprehensive investigation and adjustment. In (1), migration stimulating activity for microphage was selected as a molecular recognition evaluation system, and on the basis of the structural analysis result of a non-peptide compound/imidazolin compound having migration stimulating activity, molecular structural design was carried out for peptides having migration stimulating activity. The result of the analysis revealed that the spatial arrangement of three phenyl nuclei and the presence of basic structures were important. Among the 22 peptides so designed, only Cbz-Phe-Phe-His-NH{sub 2} showed the migration stimulating activity. For the design, a peptide molecule design system CHARMm/QUANTA/PM3 was used. (NEDO)

This paper describes discussions on future possibility of introducing hydrogen, by adding the latest data acquired in fiscal 1979 into a hydrogen energy total system calculation model. The critical cost of hydrogen is higher always than other secondary energies up to about 2030. Since it is a presupposition that hydrogen manufacturing is technologically feasible only by using the electrolytic manufacturing process, the hydrogen cost changes with the critical cost of electric power. Thereafter, if a hydrogen manufacturing process of mixed type utilizing heat from a high temperature gas reactor (HTGR) is introduced, the cost will be reduced. However, introduction of HTGR is governed by the nuclear power plan such as HTGR technology development, rather than simply by the economic performance. Value factors showing qualitative advantage of hydrogen have been assigned to different demand sectors, whereas acceptable economic performance may emerge from this effect from about 2010 in sectors having large value factors (such as 2.8 in aircraft fuels). Hydrogen contribution would be about 2.1% in 2020 and 5.5% in 2030 of the whole energy demand. (NEDO)

For the purpose of propelling forward the Sunshine Program smoothly and efficiently, a survey is conducted on inventions related to the contents of researches being conducted under the Sunshine Program. The survey covers hydrogen energy-related patents laid open in 1983. As the result of the survey, it is learned that, among the patents related to thermochemical or photochemical processes, those that relate to hydrogen production technologies using the photochemical process is found to be on the increase. There is a remarkable increase also in the number of patents related to metallic hydrides, as in the preceding year. As for their contents, many involve containers for hydrogenation heat utilization, but now novel hydrogen storage alloys are also evoking interest. As for the hydrogen fuel cell, there is an increase in the number of applications for the phosphoric acid fuel cell and molten carbonate fuel cell which are expected to be introduced into the power system. As for the hydrogen engine, the number of applications concerning alcohol-reformed gas engines is approximately three times larger than that of the preceding year. In relation with the hydrogen combustion system, many patents relate to catalytic combustion. This is probably because the technique has come to be recognized as a controlled burning method which has in itself a measure to inhibit NOx emissions. (NEDO)

A report is compiled about the above-named system being developed under the large-scale industrial technology development project. In the research and development of 'high-performance pattern formation technology,' 'stabilization pretreatment technology,' 'multifunctional sewing technology,' and 'production control technology,' the specifications for each of the component units and the impression they will give have become clear. Though within the limits of the results of operation verification tests conducted for the respective units, it is deemed that each one of them now satisfies the target value for the most part. Researches are conducted by apparel manufactures on the assumption of systematization of the Tsukuba experimental plant, their researches covering the total processing time, amount of production, part shape deformation to occur during the movement of parts, and incorrect workpiece positioning. When the results of the researches are studied, however, it is found that processing time to be consumed at each unit has to be shortened, that deformation of workpieces during processing or movement has to be lessened to the maximum extent, and that the variation in workpiece positioning has to be reduced as much as possible.

The value factors (VF) applied to them are 1.7 for the ammonia industry, 1.1 to 1.6 for the methanol industry, 1.4 for gasoline as automobile and jet fuel, and 2.8 for jet fuel. Whether hydrogen would be introduced in all of these sectors depends on conditions of introducing hydrogen utilizing HTGR heat, and the VF of hydrogen against competing energies. Therefore, case studies were performed by using these factors as the parameters. If the VF is fixed and HTGR introduction speed is accelerated, introduction of hydrogen will be accelerated in the fields of chemical materials, air conditioning and process heat. On the other hand, the introduction will decrease in the automobile and aircraft fuel fields. If the methanol VF is made smaller, hydrogen introduction will be decelerated in the chemical industry field (methanol), and that in the air conditioning, automobiles and aircraft fuel fields will be accelerated.

Described herein are the FY 1999 results of the feasibility study on the next generation liquid crystal processes. Technology for low-temperature thin film formation fabricates high-purity, high-density Si films useful as the laser annealing (crystallization) precursor by the IBD method, without using thermal annealing. Formation of thin films of a-Si and SiNx on substrates kept at 200 degrees C or lower is studied using a high-density plasma source, and the surface conditions are uniformly controlled over a large area of the film precursor. The new technology needs less power to produce the film than the conventional CVD method which uses parallel flat plates by controlling the plasma-generating region. Resources- and energy-saving using the TFT method are essential for production of liquid-crystal displays, and the techniques for forming the thin films at low temperature are studied. Reduction in wiring resistance (signal transmission delay) is studied for the next generation TFT, and it is found that the Cu film is selectively formed on TiN but not on SiO{sub 2} by the MOCVD method at 150 to 180 degrees C. Similarly, the selective film formation is confirmed in the plating technology. The comprehensive investigations for the next generation liquid crystal process technologies cover high-quality polycrystalline Si films and lithography (exposed to light). (NEDO)

The project of (research and development of methods for wide-area thermal structure exploitation) is to pursue (1) development of heat flow rate analyzers, and researches on the methods for measurement/analysis of heat flow rates, (2) researches on geological thermometers with the cores collected from test bores as the samples, (3) observation/analysis of microearthquakes, and application of the results to the geothermal structure exploitation, and (4) development, on a trial basis, small, light air drilling machines. The method for clearly elucidating thermal structures has not been well established. Therefore, a test bore was drilled to measure temperature and collect the core samples in the wide-area geothermal district at Kita Yahata-daira as the model district, for measurement of heat flows, and analysis of the cores to estimate temperature at which they are formed. Microearthquakes, which frequently occur in geothermal areas, are also observed for extended periods. This project of (research and development of methods for wide-area thermal structure exploitation) is aimed at, based on the above efforts, to estimate/elucidate depth of thermal sources by the geological, geophysical and geochemical studies, relationships between geological structures and high-temperature zones, geothermal propagation structures, and geothermal reserves.

Basic information was collected and assessed on materials and element technology for tribo materials which are expected to contribute to improvement of energy efficiency of machine/equipment having the sliding part such as automobiles. A survey was conducted of creation of substrate materials, the surface treatment method, and evaluation of coating characteristics. For an analysis of high polymer abrasion powder, the micro ATR method is effective. As an analysis method of abrasion scar, the micro ATR method is effective to specify the peeling part of coating, and the Raman method is effective for an analysis of transfer matters or abrasion powder. As a method to collect various shapes of abrasion powder, processing of material surfaces by polishing method is effective. As a dynamic analysis method, the infrared ray stress image method is effective. As an evaluation method of deficient concentration of coating, the GC-MS method is effective. For the application of high-hardness/low-toughness gas phase coating film to the sliding part, important factors are the substrate hardness, surface roughness, and film adhesiveness from the aspect of materials and the determination of pressure of the sliding face from the aspect of sliding conditions. 12 refs., 38 figs., 20 tabs.

As part of the research and development project for producing photovoltaic power generation systems at reduced cost, the R and D efforts are made for producing particle nonacceleration growth type silicon thin-film crystals. The research items are (1) research on thin-film crystals, and (2) research on cell-structuring method. The item (1) studies quantities, types and electrical properties of impurities and crystal defects in the polycrystalline ingots, produced by the Czochralski method from metal grade silicon and purified metal grade silicon stocks. Next, the substrate prepared above is coated with a thin film of silicon by the vapor-phase growth method with dichlorosilane as the source, to evaluate the thin-film crystals by measuring the crystal defects and lifetime of small numbers of carriers. The item (2) studies the effects of the solder dipping method. In addition, unevenness of photoelectric current is analyzed by a laser scanning microscope, to investigate the effects of the secondary impurities and crystal defects in the substrate crystals on photoelectric current. As a result, it is found that conversion efficiency is improved by grading the hole concentration in the p-type activated layer. The targets of 10 to 20 m{sup 2} as the area and 7 to 8% as the conversion efficiency are attained by preparing the crystals again. (NEDO)

This paper describes the achievements in fiscal 1988 on comprehensive surveys on photoreractive materials. Based on the research and development institution for the next generation basic technology under the initiative of the Agency of Industrial Science and Technology, development is being promoted on photoreactive materials, or photochromic materials and photochemical hole burning (PHB) materials (materials in which molecular structures and assembly state can be changed reversely by actions of light, leading to expectation of application thereof to ultra-high density recording, displays at high resolution, and light switches). In order to achieve smooth and efficient promotion of the development thereof, development of the related technologies inside and outside the country was surveyed and discussed. Comprehensive surveys and researches were also carried out on the common basic technologies by looking to the well-informed people for guidance on the research. This fiscal year has held joint committee meetings to which lecturers were invited to discuss respective problems in the research and development trends. In addition, as the domestic survey, the status of research and development at the Tsukuba University was surveyed on photo-responsive polymeric gels.

The aim is to establish the technology of manufacturing SnO{sub 2}/nSi solar cells using a low-temperature deposition method and thereby to reduce the cost. A 5cm-diameter wafer is subjected to a batch process, and a large-area, uniform-quality SnO{sub 2} film is obtained. A conversion efficiency of 13.7% is achieved for a single-crystal 9cm{sup 2} cell. As for the conditions of electrode formation, conventional methods are applied for bonding metals, which are Sn, Ni, Zn, etc., for the surface electrode and rear electrode. Vapor deposition is found to be the most excellent. Since it is known that ohmic characteristics improve when Cr is inserted as the base for the surface electrode rear electrodes, it is anticipated that a contact resistance value not inferior to that by vapor deposition will be achieved once the method of Cr bonding, whether by printing or plating, is established. An n-type low-cost polycrystalline Si substrate is subjected to etching under the optimum conditions, and a conversion efficiency of 9.6% is achieved for a 0.5cm{sup 2} cell. An SnO{sub 2} film is formed on a uneven surface for a reduction in the single-crystal cost, when characteristics better than those of a wafer manufactured by surface polishing are realized. Experimentally produced cells are evaluated using a solar simulator, and the result indicates that the electrode forming conditions influence conversion efficiency a great deal. (NEDO)

The R and D was intended to establish the manufacturing technology of a particle non-accelerated growth type silicon thin film crystal, for the purpose of developing a technology for enabling the production of a solar power generation system, whose price is practically 1/100 compared with that of building the system with the current technology, and the R and D was also intended to build the system using such silicon material. While a simple purification method was examined for a low purity metallurgical-grade silicon, a solar-grade silicon (SOG) was developed as the new material this year, with a solar cell experimentally manufactured having a structure directly joined to the substrate material and with evaluation carried out on the characteristic of such solar cell. The application of 'gettering' was tried which was for removing harmful impurities from the substrate obtained from such material, bringing an outlook of manufacturing a solar cell with a conversion efficiency of 10%. Concerning the SOG-Si, the efficiency of 13% or higher was attained through the improvement of the manufacturing process. This was the value comparable to the case of using a conventional high purity monocrystal wafer. Further, the application of an ion implantation method was studied for the purpose of getting a low cost. (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)

Relative to the research and development of technologies for fabricating, and assessing, materials for the constitution of high-temperature solid electrolyte fuel cells, stabilized zirconia solid electrolyte fuel cell manufacturing technologies are developed by use of thin film formation techniques such as high-frequency sputtering, plasma CVD (chemical vapor deposition), and the thermolysis of organic zirconia compound coating. As the result, it is found that high-frequency sputtering produces thin film which is satisfying in terms of cost efficiency. Furthermore, it is found that defects in solid electrolytic thin film formed by the high-frequency sputtering method, that is, pinholes and cracks, will be remedied when the coating thermolysis method is jointly applied. In the research on fuel cell power systems, column-type high-temperature solid electrolyte fuel cells are built, and a power generation test is conducted. The test is successfully completed when the output of a fuel cell of the 9-column module structure gradually increases until a maximum output of 110W is achieved. (NEDO)

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

This paper describes the achievements in fiscal 1998 on developing a high-efficiency human body measuring device. Object building with high compatibility is requested in recent years, and a high-precision and high-efficiency measuring device for three-dimensional human body shape data is demanded. The ultimate target for the device is high-precision measurement of about 1 mm in about one second which is the time for human being capable of staying immovable. In association with proliferation of product designing by using a computer, the needs for data handling on computers are increasing sharply in industries. Proposals have been made by ISO and CEN on the standards for morphological characteristics of human being, inducing progress in international standardization of human body size and shape data. Structuring a database is also planned on three-dimensional shape data mainly in the U.S.A. The Human Life Engineering Research Center is studying development of a measuring device to measure human body types and sizes at high speed and accuracy. The device combines three-dimensional measurement by using an optical method with high-performance computerized image processing. The measuring device is supposed to be capable of outputting the measurement results as the size and three-dimensional shape data, so that the results can be applied to product designing quickly.

An excellent sintered film is acquired when 0.3% SO{sub 4}{sup 2-} is added to the raw material for the preparation of a CdS film starting material. A CdS film is burned at 600 degrees C, this temperature being lower than the conventional temperature (690 degrees C), and then reburned at the same temperature of 600 degrees C. The resultant device is found low in performance. For the preparation of paste for CdTe film, the material is pulverized into grains of the same size, and this stabilizes device performance. Burning temperatures are also reviewed. Carbon electrodes, Ag-In electrodes, etc., are also reviewed, and 92% of the devices produced under the currently optimum mass production conditions are found to have a conversion efficiency of 4% or higher. The best one is found to exhibit a conversion efficiency of 8.29%. In the study of the method of module constitution, the structure of cross section is improved, the manufacturing process is stabilized, and simplification is carried out. The reliability of the 5 times 10cm{sup 2} substrate device manufactured in this fiscal year is found greatly improved. It is found also that degradation it suffers is attributed to an episode occurring in the interface between CdTe and carbon. A module in which two of the devices manufactured here are connected in series is tested. It exhibits no degradation when exposed to outdoor conditions, but its conversion efficiency is substantially degraded in a moisture test. (NEDO)

This paper describes surveys on patent information about hydrogen energy. For the thermo-chemical hydrogen manufacturing method, considerable number of experiments have been carried out, and discussions have been given on possibility of establishing the cyclic performance. However, in the patent aspect, many of them are the discussions on desk. The electrolytic hydrogen manufacturing method is considered to have reached the limit of improvements, whereas no new patent applications have been filed on electrodes and diaphragms. The number of patent applications on storage and transportation of hydrogen is largest in those for hydrogen storing alloys. However, patent applications having contents worth discussing are relatively few. What is common to patents related to safety assurance is that the object is not necessarily focused on hydrogen, but in many cases relevant to combustible gases in general. In the hydrogen fuel cells, a tendency can be observed of using higher temperatures and pressures, such as in the one using phosphoric acid as electrolyte the operation temperature of 135 degrees C or higher. Amount of platinum added into electrodes is decreasing. Few patents are found that tackle squarely with hydrogen fueled engines. An invention is desired on a new engine using hydrogen as fuel. No patents can be found that have contents responding to the current problems to which the hydrogen combustion study is facing now. Solution is expected on the hydrogen flame dilemma of NOx generation and reverse ignition. (NEDO)

Emphasis was placed on the research on a planar apertured near-field head and a super-RENS (super-resolution near-field structure) method, as a near-field application element for replacing protruding probes, which has a number of difficult points in developing near-field recording into a practical system, and as a recording and reproducing method. The super-RENS method, as a result of the examination, has become capable of recording/detecting a mark of the minimum 60nm diameter, by the near-field, under conditions such as the most advanced optical disk size and the number of revolution of the disk. This means that a high density recording is possible which is at least 40 times as dense as a DVD (digital versatile disk). It was confirmed by an experiment that the high density was possible in the track pitch direction by the super-RENS method. As a result of the examination on the behavior of the near-field in the super-RENS disk, it revealed that signal detection by the transmitted light which had not been tried before was effective for the improvement of the performance. The smallest detectable mark size was 80nm, in which case CNR (carrier to noise ratio) was 6.4dB. These values are approximately the same level as in the signal detection by reflected light, and are insufficient to verify the superiority. (NEDO)

Research was conducted for the development of a highly reliable flowmeter which enables the efficient calibration of flowmeters at oil plant working sites and the international comparison of oil flow standards, and is also usable as the standard of oil flow at private businesses. In this connection, international research cooperation was carried out with Physical Engineering Research Institute, Germany. In the study of rotors, tooth profiles were contrived and various analyses were conducted for each screw type. In the study of flow inside flowmeters and of structures, screw-type volumetric flowmeters of K Co. were subjected to various tests for structural analysis, and visible models were fabricated for the clarification of flow characteristics. In the study of servo systems and instrumentation, several types of pressure difference detecting mechanisms were newly contrived, and servo control systems were investigated. In the study of trial manufacture and evaluation, the UF-VI080{alpha} cast iron (FC250) rotor flowmeter and the UF-VI080{alpha} aluminum (A7075BE) rotor flowmeter were examined. Both failed to achieve the target precision of {+-}0.2% in the case of gasoline but, in the case of kerosene and heavy oil, the target levels were sufficiently met. (NEDO)

This paper describes surveys in fiscal 1979 on patent information related to hydrogen energy. For the hydrogen manufacturing cycle based on the thermo-chemical method, many patents are related to HI decomposition and separation. A number of technologically superior patents were found in the electrolytic method, but those applicable directly to water decomposition development in the Sunshine Project are not many. The number of patents on metal hydrides in relation with hydrogen storage and transportation has shown some increase, but no change in the qualitative aspect. In safety assurance, many proposals were seen relating to earthquakes. Patents on hydrogen fuel cells decreased in number as a whole, while half of the domestic patent applications is for alkaline electrolyte type fuel cells. In contrast in other countries, many patents are related to the second and third generation fuel cells, not to speak of the first generation, indicating that Japan is standing behind. Technologies to use hydrogen engines practically are concentrated on establishment of hydrogen storage and transportation methods and development of systems with high total energy efficiency, which are reflected in patent applications. Combustion device related problems are in NOx emission suppressing technologies and reverse ignition preventing measures, but trend is lacking in applying for patents that endorse technological progress in this respect.

Iodine-alkaline earth metal (Mg, Ca) cycles are discovered, and the one with Mg is found excellent. The reaction consists of four stages, that is, Stage (1) where 1/5Mg(IO{sub 3}){sub 2}+MgI{sub 2}(aq) is obtained from 6/5MgO+6/5I{sub 2}, Stage (2) where 1/5MgO+1/5I{sub 2}+1/2O{sub 2} is obtained from 1/5Mg(IO{sub 3}){sub 2}, Stage (3) where MgO+2HI is obtained from MgI{sub 2}+H{sub 2}O, and Stage (4) where H{sub 2}+I{sub 2} is obtained from 2HI. Since there is much iodine and water at Stage (1), MgO thrice MgI{sub 2} in mol is added for reforming and concentration. At Stage (4), where the decomposition rate is as low as 17-27% with the equilibrium dissociation reaction proceeding at 300-700 degrees C, hydrogen is selectively separated by permeation through a porous diaphragm for the acceleration of the reaction. As for materials for the device, they are narrowed down to high-priced ones, that is, Ta and Nb for Stage (1), Ni-50Cr for Stage (2), and Mo etc. for Stages (3) and (4). Under the circumstances, a study is started for the development of a chemical vapor plating process which is high in corrosion resistance. Other cycles such as sulfur-based cycles and hybrid cycles are also investigated. (NEDO)

This report is for the results of fiscal 1979 on a solar cooling/heating and hot-water supply system for newly-built private housing. The research reports for fiscal 1974 to 1978 are as reported so far; for example, the research on energy-saving construction including thermal insulation method was used in an experimental housing completed in fiscal 1976. The solar heat collecting device was built in the experimental housing by increasing the scale of and utilizing the heat collecting device of a vacuum glass tube type on which research was done before fiscal 1975. The absorption refrigerating machine incorporated in the housing was of a forced circulation type which was high in temperature stability using the result of the research carried out until then. In fiscal 1979, as in fiscal 1978, one year residential experiment was conducted in which a family of a couple and two children lived in a house under an improved system as a result of a system variation and the like, and made an evaluation on the performance. Simultaneously, a control management system was developed in which a micro-computer was introduced for the purpose of improving the system performance, with the operation carried out under the micro-computer control. In addition, a fundamental experiment was also completed concerning a long-term heat accumulation by underground heat reserve. (NEDO)

Evaporation/diffusion tests are conducted in which 10 liters of liquid hydrogen is discharged instantaneously from a certain altitude toward the middle of spill surfaces. Four types of spill surfaces are used, which are soil, concrete, crushed stone, and water. Tests of continuous discharge of 50 liters of liquid hydrogen and of ignition/combustion are also carried out. The evaporation/diffusion phenomenon of liquid hydrogen is found to be greatly varied dependent on the spill surface type. The rising speed of the visible vapor mass is fairly great, and is approximately 1m/sec or more on any of the spill surfaces. Vapor diffusion is the fastest on the crushed stone spill surface where lateral expansion is the least, which is excellent from the viewpoint of safety. It is found that the rise of the vapor mass formed just after liquid hydrogen discharge is attributable to its own buoyancy. The flame of burning hydrogen is colorless and transparent, barely visible just like shimmering heat haze. When sodium bicarbonate power is lightly scattered all over the flame, it becomes obviously visible because of its turning orange due to the color flame reaction of sodium. Documentary records are also investigated. (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 investigation and discussion on effects of introducing a superconductor power application technology. The generator sub-committee has compared features, technical problems and development expenses in the first and second proposals, but has not reached the final conclusion. The first proposal is targeted for early realization of 200-300 MW class generators with development cost of six to seven billion yen and a development term of seven years. These developments raise largely towards practical application the levels of material technologies, fabrication and processing technologies, and analysis and design technologies. The second proposal is intended of developing 200-300 MW class generators targeted for increased diameter, as a reduced size machine of a 600-MW generator being a future generator. It will take development cost of eight to nine billion yen with the period of nine years for the development. Majority of the technologies required for developing the future 600-MW class generator can be demonstrated. The AC superconductor device sub-committee has investigated design examples, clarified the specification requirements, and investigated and studied the development measures. The oxide superconductor sub-committee has investigated and studied making wires and conductors, and device application feasibility, but has not reached the stage of presenting specific research and development methods. The practical application strategy sub-committee has also not been able to present a collective measure because of difficulty of making future prospect on the electric power business. (NEDO)

This paper describes fundamental surveys and discussions on technological development in small businesses centering around venture business entities. These business entities have built their competitive superiority by making mainly studies on practical application placing importance on marketability, whereas technological lead-time must be shortened. Making the systems to achieve this goal is demanded. Competitions often take place in markets for small quantity production with large model variety or small model variety, where one is importantly required to establish his specialty expertise. Also desired is the network type business management aimed at developing horizontal business spread while exhibiting the corporate identity. Academic and governmental organizations are demanded of establishing institutions that can provide necessary support when it is required, against shortage of business resources such as fund and human resources. Since the circumstances accompany uncertainty that the success experience and know-hows attained in the past may not necessarily be viable any longer, business management judgements should be made upon collecting effectively the useful items of information including technological seeds. On the microscopic base, markets still have the wide plains at the foot for future growth and development. What is required is effort in business management to improve supply preparedness and strengthen the competitive edge to match the demand growth. Support in the fund aspect is also indispensable to enter into new areas. (NEDO)

This project is aimed at establishment of techniques for pollution-free production of II-VI group compound semiconductor type solar cells. The research items are (1) measures against aging, (2) methods for production of II-VI group compound semiconductors and for forming their joints, and (3) method for assembling solar cell devices.For the item (1), the aging tests are conducted for sintered film type CdS/CdTe solar cells. The C electrode is found to be less aged than the others. The aging tests for the CdS/Cu{sub 2}S cells indicate that it takes 10 years or longer for the performance to be halved under commercial conditions. For the item (2), the sintered film type CdS/CdTe solar cells can be produced by a mass-producible process of screen printing and belt furnace. This production method is promising for producing the solar cells at low cost. For the item (3), it is found that series resistance of the solar cell devices increases as the assembly area increases, resulting in decreased conversion efficiency. The divided structure of the CdTe layer is desired to avoid the above problem. Dividing each unit device increases intrinsic conversion efficiency, but decreases effective power generation area ratio. It is therefore necessary to improve printing precision. (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)

The research involves tests and studies conducted for the evaluation of corrosion resistance of various metallic materials in molten iodine and for the selection of materials to stay usable under iodine-handling conditions. In fiscal 1982, an iodine transportation system is studied, and corrosion tests are conducted for panels of carbon steels, various stainless steels, titanium, niobium, tantalum, etc., of the grade available in the market, under the conditions where the temperature is 113-170 degrees C, I{sub 2} contains 0-10wt% H{sub 2}O, and the gas phase is of N{sub 2}+O{sub 2}. It is made clear as the result that the effect of water present in I{sub 2} is fairly grave while the influence is but a little of the intensity of temperature and the amount of O{sub 2} gas on the corrosion rates of the respective materials, that materials other than niobium and tantalum are not usable as corrosion resistant materials, etc. In a real device, it is recommended that composite materials be used in the form of a liner or the like because both niobium and tantalum are high-cost materials and therefore create economic disadvantages if employed for the construction of pipes, heat exchangers, etc. (NEDO)

The effort aims to develop and commercialize hardware and software for identifying the individual who during business transaction affixes his signature to a settlement form with a ballpoint pen or the like. Basic technologies of a tactile sensor are utilized in the construction of a ballpoint pen structured like a tactile sensor with an oscillator attached to the ink holding shaft for the pen to sense the touch of the paper. Fluctuation in the tool force exerted on the paper surface of specified hardness when writing or drawing letters or patterns are converted into frequency data. The small but highly sensitive 2-dimensional angle detecting system, developed Professor Satoshi Kiyono of Tohoku University, is incorporated into this ballpoint pen for achieving higher precision with the angle detection limits and the resolution taken into consideration. Since a strong correlation is to exist between the force exerted in the direction of roll of the ball and the angle of delicate inclination of the ink holding shaft end, tool force application and changes in the force may be continuously traced. When they are combined with a tool force detecting mechanism, a digital pen mechanism results which is capable of simultaneously reading parameters of the X, Y, and Z axes. (NEDO)

To put it forcibly, the gas leakage problem should be solved to prevent disaster accidents caused by high pressure gas. From this point of view, the R and D of the safety technology were conducted for the process of hydrogen distribution/consumption. The literature collected was studied, and the present situation was again recognized of the hydrogen gas industrial circle in Japan. At the same time, hydrogen physical properties and the peculiar dangers derived therefrom were comprehensively arranged. Examples of accidents tell realistically how dangerous hydrogen is, and give suggestions for treating hydrogen safely. We can see a lot of examples of how to treat liquid hydrogen in the U.S. It seems that there are no effective methods to detect the leakage of hydrogen, and methods to meet each case are required. To sum up, the research results show how much safety of the distribution/consumption process is secured under the present safety technology and legal regulation. At the same time, those also indicate how much the safety can be enhanced technically in the future. (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.

This project is aimed at development of optimum combustion technology with diversified fuels, e.g., naphtha and LCO, for gas turbines and others as power sources for topographical energy supply. The combustion under the microgravity is also investigated using the underground facilities at Japan Microgravity Center. Described herein are the FY 2000 results. For construction of combustion model and simulation, the combustion reactions for various liquid fuels are simplified to calculate ignition delay, adiabatic flame temperature and laminar burning velocity with an error less than about 3%. The microgravity combustion experiments are conducted for spray dispersed into a cylinder, to find flame propagation velocities changing with the vaporization characteristics of liquid fuels, and also to construct the combustion models. The premixed turbulent combustion simulation program is developed using a probability density function and analyzed. Development of new combustion technologies includes the study themes of flame propagation and combustion of the air mixture of the multi-component fuel in which the spray exists, combustion characteristics of the droplets of diversified fuels, and combustion of gas turbines with diversified fuels. A propane/air mixture shows different flame propagation characteristics whether it contains kerosene or LCO droplets. The effects of electrical field intensity in the combustion zone on combustion of fuel droplets are elucidated. (NEDO)
