    In the use of hydrogen as fuel, there is the problem on NOx emission. The amount of NOx emission is not as much as in the use of coal or oil, but is more than in the use of natural gas or town gas. However, it can be said that hydrogen is an ideal fuel if considered that it does not emit other air pollutants such as CO, HC and soot/dust which are usually associated with hydrocarbon base gas fuels, and also that hydrogen forms a circulation system which is ecologically sound. The flame of hydrogen is non-luminous, but the flame temperature is high. The formation of NOx depends strongly upon the flame temperature, and therefore, in the design of hydrogen burner, it is necessary to well mix it with air and to avoid the production of the local high temperature region. Further, when using hydrogen to large boiler, the combustion technology to control NOx reduction is needed. About the hydrogen flame, the matter to be noticed is an experimental result that NOx reduction was observed by adding trace ammonia to hydrogen gas. If this method can be successful, NOx can be reduced with no increase in fuel consumption. It leads to hydrogen's reaching a position of clean energy. (NEDO)

    The survey/research project is implemented for establishing environment-compatible energy systems in urban areas by constructing wide-area heat supply networks to exchange energy among cities. This project studies, taking Kanagawa Pref. as the model area, distributions of unutilized energy sources, and possibilities of their utilization for heat supply. There are large quantities of unutilized energy, including waste heat from power plants, general works and cleaning works, and low-temperature waste heat from, e.g., sewage and pumping systems. The district air conditioning promotion areas are selected from those consuming large quantities of heat energy in the prefecture, and their characteristics are grasped. The effects of the networks on total energy consumption of the entire prefecture are estimated for the cases of introducing the district air conditioning systems or wide-area heat supply networks in these selected areas. Introduction of optimum advanced heat utilization systems in stereotyped areas is also considered, in order to predict the effects of introduction of wide-area heat supply networks. (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.

    This project started in FY 1993 to survey the actual state of industrial use boilers. Based on the results of the survey, in fiscal 1995, 1996 and 1997, no improvement of the present technology which has limits, but the development was made of the oxygen combustion and element technology which are factors for heightening boiler performance with a new idea first in the world. In fiscal 1998, a target for the overall thermal efficiency of 105% was settled by testing a pilot plant where the element technology was integrated into the small once-through boiler, flue/smoke tube boiler, water tube boiler, etc. In fiscal 1999, the target of the overall thermal efficiency of boiler was reached by a pilot plant test to clarify combustion characteristics, heat transfer characteristics, environmental characteristics, etc. Further, effects of energy saving were increased by the adoption method of oxygen supply equipment. Concretely, an overall boiler efficiency of 105.73% exceeding the targeted value of 105% was achieved at a pilot plant of actual scale, by concentrating the results of each of the element technologies such as 'oxygen combustion,' 'condensation type flue gas heat exchanger,' 'high performance combustion control device,' and 'rapid rotating auxiliary machine.'

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

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

    The R and D of chromium alloys had been conducted till about the 1970s, which brought the unfavorable results. That's why chromium alloys are brittle at normal temperature and difficult in processing. However, the technology development in recent years review them. The development is earnestly desired also of the materials exceeding the Ni base super alloys which are heat resistant materials for power generation. Cr is rich as resource and light-weighted, and the oxidation film is stable and self-restorational at high temperature. The alloys are excellent in processability at normal temperature and excellent also in toughness. The nitrogen content is strongly concerned with brittleness and intergranular fracture at normal temperature. Therefore, Cr alloys were trially manufactured by the HIP sintering/hot forging method using electrolytic Cr powder with high-purity (99.99%) and low-nitrogen (10ppm) to study a possibility of improving brittleness at normal temperature, mechanical properties at high temperature, oxidation resistance, high-temperature corrosion resistance, etc. A variety of excellent characteristics of Cr alloys were made clear. However, also made clear were the problems: strength is low at normal temperature/high temperature; screw process is impossible because of high notch sensibility; those are not almighty high-temperature corrosion resistant materials. Further efforts should be exerted for the commercialization. (NEDO)

    Experiments were conducted on the plasticity processing of heat resistant ceramics making use of the viscous deformation of amorphous ceramics in the supercooled liquid temperature domain. Concerning the preparation of powder of amorphous ceramics, the plasma rotating electrode method of Institute for Materials Research, Tohoku University, was employed, and a bamboo leaf shaped amorphous flake was successfully fabricated by increasing the arc discharge current. In a search of texture easy to turn amorphous, it was observed that Al{sub 2}O{sub 3}-La{sub 2}O{sub 3} had a supercooled liquid domain of as large as 70K, and this enabled a conclusion that it was a promising candidate for hot molding in a supercooled liquid domain. In an experiment of molding in a supercooled liquid domain, Al{sub 2}O{sub 3}-Gd{sub 2}O{sub 3} was used in a press molding process. As the result, a compact bulk mold was obtained in a temperature domain far lower than in the case of conventional sintering. Crystallization had already advanced in all the molds experimentally fabricated by press molding, and this disabled a study of characteristics to be exhibited by an amorphous mold, but it was found that they had a compressive strength of approximately 1,800MPa.

    In order to help discuss the system and environment improvement to promote freer flow of Japanese researchers, surveys and discussions were given on the actual status in America and European countries. In the U.S., results as independent researchers are demanded from the very early time under the severely competitive environment, wherein the fair evaluation of the results allows the researchers to step-up the positions and research environment to which the researchers are oriented. In Germany, a function to promote researcher mobility is available as a system, such as promotion of exchange with other sectors during researcher education course (the internship system at the fourth grade in a university, and power training and performance record building at the Max-Planck Institut during the long term of post-doctoral period before attaining a professor position), or prohibition of inviting university professors into the same faculty. The actual status of Japan not having high mobility of researchers has been caused by the system based on the lifetime employment, whose shortcomings include stiffness in personnel affairs, and reduction in activities of researchers due to aging.

    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)

    In the paradigm that propelled polymer chemistry, there are involved the establishment of polymer concept, engineering plastics, regulation of higher ordered structure, and precision polymerization. The first two produced the polymer chemistry era in the 20th century. The regulation of higher ordered structure and the precision polymerization are the fundamental technologies supporting the polymer chemistry of the 21st century. The precision polymerization is a technology for regulating the stereospecificity, sequential structure, and molecular weight of polymers by regulating atoms and molecules and is referred to the following important techniques to be concrete. In the precision addition polymerization, stereospecific regulation and purification of active site to give living polymers are required while, in the precision condensation polymerization, regulation of condensation probability process to be secondary Marcov chain is necessary, as is the establishment of non-defect condensation condition avoiding high temperature deterioration and the like. In the biomimetic precision polymerization, key issues are the method of incorporating molecular recognition control and sequential structure control by living organs into an industrial process. If the higher ordered structure can be regulated by the precision polymerization, it is possible to obtain numerous high performance/high functional materials such as superconductors. (NEDO)

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

    This paper summarizes problems in utilization of solar energy, their solutions, features, the currently achieved results, and prospects. With regard to water decomposition using semiconductors, simultaneous generation of hydrogen and oxygen has already been achieved, and there is high possibility of raising the efficiency by improving catalysts. Water decomposition using metal complexes has acceleration of charge isolation as the largest problem, whose prospect of solution is not necessarily bright at the present time. Photo-catalytic reaction is a field to be discussed as one means of developing a new synthesizing method from the viewpoint of organic synthetic chemistry. Conversion into electric energy that uses a photovoltaic process has high efficiency, and is a field to be noted. In photo-energy conversion by means of photo-synthesis, living organisms performing hydrogen production at high efficiency have been discovered. Important studies include the studies in terms of chemical engineering using these living organisms, improvement of breeds by gene manipulations, and studies that utilize living organisms or part of the constituting components.

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

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

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

    Experiments were conducted under microgravity for findings on the creation of microspheric photonic materials which are high in sphericity. The experiments were carried out at the fall type microgravity facility of Japan Microgravity Center (JAMIC). In the experiments on the ground surface and under microgravity, glass specimens of 3BaO-97B{sub 2}O{sub 3} mol%, 4BaO-96B{sub 2}O{sub 3} mol%, and 2SrO-98B{sub 2}O{sub 3} mol% were tested. They were heated, melted, and cooled for the on-site observation of phase splitting in them. It was found as the result that, in the case of specimen 3BaO-97B{sub 2}O{sub 3}, the phase splitting start under microgravity was similar to that on the ground surface while the nucleation velocity was lower under microgravity. Specimen 2SrO-98B{sub 2}O{sub 3} mol% exhibited an approximately 0.5-second delay in its phase splitting start under microgravity as compared with its ground surface behavior. As for the nucleation velocity under microgravity, the value was same as that on the ground surface in the first half but, in the second half, it was lower than that on the ground surface. The said approximately 0.5-second delay in the phase splitting start was, when the cooling rate was taken into consideration, attributed to an approximately 6.5 degrees C fall in the phase splitting start temperature, and this suggested that phase splitting was suppressed under microgravity.

    Described herein are the FY 2000 results of the research study on environmental information network formation. The Internet is experiencing an explosive increase in volume of information distributed therethrough. This is accompanied by increased problems related to information searches, information exchange security and information-reliability guarantees. First in demand are excellent portal sites, and second are sites that can be relied on to responsibly provide information. Cooperation with the real world off the Net is of particular importance, because the operating organizations, e.g., sites, will lose their raison deter, unless they clarify their unique abilities and characteristics under the tendencies towards broadened bands and ubiquity. The public sector, on the other hand, is highly reliable, accumulates a large volume of information, and has high network capacity. It has various functions, e.g., supporting the activities pertaining to ISO standards, and promoting the activities, e.g., those for educational programs, interdisciplinary exchanges by researchers, and matching of various organizations. The international cooperation for environmental information needs construction and operation of the networks, and construction of the infrastructures in the developing countries. If information becomes more ubiquitous, a chaotic sea of information will result. NEDO is strongly obliged to serve as the beacon, because it has established a huge volume of environment-related technologies, information, and networks. (NEDO)

    Described herein are research and development of superhigh-sensitivity photocurrent conversion devices. The huge photocurrent multiplication effect exhibited by a thin film of organic pigment semiconductor is expected to be applicable to various new devices, e.g., superhigh-sensitivity, intelligent optical sensor families and photocurrent devices. Photocurrent multiplier thin films of perylene is prepared by an ionized cluster beam method, to evaluate their structures and photocurrent characteristics as the basic knowledge for controlling their characteristics by the ion engineering procedures. Photocurrent multiplier thin films of new, two-layer structure are developed, and improvement and stabilization of their characteristics are studied. Increasing sensing sensitivity by, e.g., introduction of p-n junction and reducing dark current resulting from the light memory effect are found to be effective to improve the S/N ratio. An organic EL light-emitting layer capable of positive/negative feedback, as one of the elementary techniques for realizing intelligent devices, is made on a trial basis and evaluated for its characteristics, and studied for its application to photocurrent multiplier thin films. Functional devices in which the arithmetic and controlling functions of the thin films are utilized are also studied. (NEDO)

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

    The investigation is made to provide the data which widely cover various characteristics of aged persons for the general designers who design equipment and environments for aged persons. It is found, by the tests for measuring sight and hearing sensations of the aged, that they generally need higher sound to hear; frequency of alarming sound is preferably lowered from 3,000 to 4,000Hz now used for the equipment to 1,000 to 2,000Hz, and the level at which sound can be heard is significantly different from that at which the announcement can be understood. For evacuation order or the like, for example, it is necessary to announce the disaster site and evacuation routes, which the aged hear for the first time, especially slowly and distinctively. The database of body functions of the aged are improved by correcting the problems associated with depth of strata and poor prospects, frequently pointed out by those who look up the data from the daily actions, in such a way that the system can be easily looked at from notices for each function position of the product and also from the related human characteristics.

    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.

    In order to identify the actual status of geothermal reservoirs, development is made on a technology to detect cracks in a geothermal reservoir. This fiscal year has launched development of a PS sonic logging device of well wall compression type, which is considered most effective in crack detection. This device has a number of new development elements such as a mechanism to have a transmitter and a receiver compressed on a geologic stratum to send sonic energy directly into the stratum, simultaneous use of S-wave having excellent characteristics in evaluating crack faces quantitatively and calculating porosities, and a cooling mechanism for electronics installed in the wells. Combining this with a micro seismogram log scheduled to be fabricated in fiscal 1976 will form the mainstream of crack face detection. A continual flow meter measures behavior of steam and hot water to identify flow-out or flow-in patterns and depths of fluid in wells under flowing condition. Adding this meter to temperature and pressure elements scheduled to be developed in fiscal 1976 will provide data to give an important guideline in underground heat production. This meter was attempted with enhancement in heat and pressure resistant characteristics and stabilization of operation for design and fabrication, which were carried out using the spinner flow meter as the base.

    Demands for constellation satellites were surveyed and satellite systems were studied for extracting basic technical tasks relative to constellation satellite systems and for drafting space verification plans. For a constellation satellite system to accomplish its missions, two or more satellites have to be simultaneously navigated. It is assumed that its field of application will cover earth observation, information communication, risk management, disaster prevention, and the like. With such applications taken into consideration, surveys and studies were conducted about the need and marketability of constellation satellites, need of state-level involvement, and requests for missions to be imposed on a constellation system. For plural satellites to satisfy mission requests by coordinating with each other, it will be necessary to develop basic technologies, such as navigational guidance, communications control, system autonomous management, and operation on the ground. Functions and performance that a constellation satellite system are requested to have and basic technologies to be studied and developed were extracted, and space verification plans were drafted.

    The paper reported on the research, design, and evaluation on a system to recover by sedimentation magnesium from the brine in the salt manufacture by solar evaporation in Mexico, and a system to recover by adsorbent lithium, boron, etc. from the brine of the solar pond salt field in China. In the case of Mexico, an overall recovery system was developed, but in the evaluation of economy of the system, it cannot be said that the system is feasible even if assuming that the required fresh water can be secured. It was found out that the economical efficiency largely depends upon the cost of hydrated lime and the selling price of magnesia clinker. In the case of China, a plant for production of 500 tons/year of lithium carbonate was conceptually designed to evaluate the economical efficiency. As a result, the internal profitability of the plant is not so high, approximately 6%, though continuously profitable during the operation of 15 years. It was indicated that the project was not economically very efficient. 164 figs., 44 tabs.

    Information systems, mainly aided by computers, are becoming increasingly important, contributing to development of wide areas of societies and economics, to begin with. However, few developing countries have established sufficient information systems, in spite of their strong desires to do so, which will further widen the gap between them and advanced countries, where these systems are acceleratedly advancing. Given these situations, Center of International Cooperation for Computerization (CICC) has been implementing various projects for providing assistance to and cooperation with oversea countries which are trying to develop information systems. This report summarizes the project, which CICC has been commissioned by NEDO as part of the cooperation programs, for manufacturing technology supported by advanced and integrated information system through international cooperation. It outlines the research cooperation memoranda NEDO has concluded with Indonesia, Malaysia, Singapore and Thailand, and the authorities of China, Indonesia, Malaysia, Singapore and Thailand. (NEDO)

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

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

    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.

    The research and development were conducted jointly with Europe of an environmental harmony type high efficient catalyst which enables clean combustion and NOx removal in polluted gas in combustion flue gas, etc. In the research and development of NOx removal catalyst such as zeolite base, reformation of mostly mordenite was done by ion exchange, ion implantation, skeleton element substitution, etc. A possibility was found out of applying the membrane formation method except ion implantation as reforming means. In the R and D of the complex oxide base NOx removal catalyst, it was found that the catalyst carrying copper and silver on silica and layer clay compound under optimum conditions shows peculiarly high activity, and there is little decrease in the activity, but rather increase in it even under vapor existence. An evaluation was made of NO resolution of direct resolution element carrying noble metal electrolyte on solid electrolyte, finding out that the highest NO selectivity is shown with Pd as electrolyte and at a baking temperature of about 1300degC. Development of high- and low-temperature catalysts was also made. 417 refs., 286 figs., 63 tabs.

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

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

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

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

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

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

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

    Development is intended to be made on fundamental combustion control technologies applicable to high-performance industrial furnaces that can reduce energy consumption and respond to environment preservation requirements. With an intention to achieve reduction in combustion exhaust gases such as carbon dioxide and nitrogen oxides, fundamental studies will be made on factors to decide flame shapes as represented by high-temperature combustion and flame shape control by utilizing microgravity environment, and researches will be made on combustion systems. Devices required for the experiments were fabricated to evaluate critical combustion characteristics of flames in furnaces including industrial furnaces, analyze and evaluate flame control parameters, and study low-pollution combustion technologies. Experimental methods acquired by 1997 were used for the experiments under the microgravity environment. Evaluation experiments were performed on flame shape control technologies and flame radiation characteristics, and basic experiments on the low-pollution combustion technologies. With these experiments, elucidation of the combustion mechanisms was launched by analyzing and evaluating the acquired data. A flame experimenting device for high-temperature preheated air completed by fiscal 1997 was used to acquire such combustion characteristics data as NOx discharge characteristics when the high-temperature preheated air is used. Based on the result thereof, verification was carried out on simulation models. (NEDO)

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

    Hydrogen gas as material is produced mostly by steam reforming of hydrocarbons, and includes a considerable amount of impurities such as carbon dioxide, nitrogen and oxygen. The concentration of impurities in the refined gas is approximately 1ppm. In the liquefaction process of hydrogen liquefaction plant, the gases entering the low temperature portion near the free expansion valve (J-T valve) are mostly oxygen and nitrogen. When oxygen is solidified, attached, accumulated near J-T valve, it incurs a possibility of exploding for reason of impact force, etc. by contact with the valve portion. A mixture of hydrogen and oxygen ignites at the minimum value of approximately 0.02 milli-joule, and therefore it has great danger of explosion. As viewed from a point of danger prevention, there is a possibility of explosion when the hydrogen-oxidizing agent mixture is formed. Accordingly, it is necessary to conduct an experiment for confirming the explosion at J-T valve portion. From viewpoints of prevention of explosion accident and running operation, it is necessary to experimentally grasp the definite allowable oxygen concentration. Further, it is necessary to establish a technology to continuously and accurately measure the concentration of trace impurities in hydrogen gas. (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.

    The paper described the present situation of the waste treatment system for the environmental engineering and the problems. The final waste treatment plants are in the tighter and tighter condition, and therefore the waste treatment system ought to be changed to a system in which importance is placed on the size reduction, weight reduction, and recycle. Accordingly, the waste treatment system becomes more characterized as a resource feedback process, and should be given more credit as a system for production of secondary resource. The problem is arrangement of conditions of technology, cost and legislation system for smoothing such recycling flow. Of course, it is natural that the most important subject of the system is to secure the environmental preservation by the waste treatment. As future subjects, needed are understanding of the waste treatment as a resource reproductive system, relation with other industries, and review of the legislation system. In consideration of technology, cost and environmental loads, required are proposal of validity of the recycle level limit and a future image of the system structure, and policies for promoting and supporting the recycle business. 47 figs., 104 tabs.

    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)

    This paper describes the achievement in relation with the mine waste water treatment technology utilizing biomass, from among the promotion projects for research cooperation with China. Waste water is converted into ferric iron (Fe{sup 3+}), which precipitates at low pH, by utilizing iron oxidizing bacteria which use ferrous iron (Fe{sup 2+}) in the waste water as the energy source, and is precipitated and removed by using low-cost calcium carbonate as a neutralizing agent. Fiscal 1998 has performed eight site surveys with 47 persons in total. The main survey items are the study and guidance of pilot plant operation and the survey on measures to prevent occurrence of contamination by heavy metals in Wushan Mine. Additional site surveys were made at Dexing Mine and Yinshan Lead/Zinc Mine. Continued from fiscal 1997, consumables required for the pilot plant were purchased, and items of the bench-scale testing equipment used by Japan for domestic researches (an oxidation and neutralization testing equipment and a copper recovering and testing equipment) were transported to China. The operation research data of the pilot plant were put in order and analyzed. This paper summarizes the concept design of the shaft waste water treatment facilities for the north mine in Wushan Mine, and the surveys on measures for heavy metal contamination sources. (NEDO)

    Since ion implantation causes material degradation by formation of crystalline defects, and hydrogen embrittlement deteriorates material strength, reduction of such defects has been positively studied. Study was made on a new active application of hydrogen separation into ion implantation defects. After H ion implantation of a proper depth into single-crystalline Si and SiC and successive annealing, single-crystalline films of sub-micron to several micron thick were obtained by hydrogen-induced delamination at the implantation depth due to hydrogen embrittlement in crystalline defects. The implantation depth is dependent on implantation energy. H atom forms (111) face defect through connection with dangling bond of crystalline defects. This crystal face defect forms a delamination plane through (100) face cleavage. This hydrogen embrittlement delamination by ion implantation is applicable to production of light-weight high-efficiency single-crystalline Si solar cells, and large single-crystalline SiC wafers as new resource saving process. 33 refs., 19 figs., 2 tabs.

    Liquefaction characteristics of coal specimens, collected from many locations across the world, are determined so as to make clear the correlations between coal type and liquefaction reactivity. Conducted for this purpose are the analysis of chemical structures of the specimens, liquefaction tests in an autoclave using various catalysts and medium oils, liquefaction tests in a 0.1t/d bench plant, investigation of the constituents of the generated oil and their separation, and the secondary stabilization treatment for the commercialization of the product. The reaction tower is kept under constant conditions, the state of the liquid mixture in the reaction tower is evaluated by tracking the flow of coal out of the reaction tower after switchover from anthracene oil to coal paste, the gas flow in the reaction tower is estimated by tracking time-wise changes in the concentration level of inert gas at the reaction tower outlet port, the inert gas having been injected in pulses into the reaction system operating under the reaction conditions. For the implementation of the above-mentioned steps, a system is designed and constructed for directly collecting samples from the vapor phase section in the reaction tower operating under given reaction conditions (temperature: 400-450 degrees C, pressure 150-300kg/cm{sup 2}), and experiments are conducted to collect gas/liquid equilibrium data in the reaction tower under the given reaction conditions.

    The present investigative studies are intended to propose measures of arranging conditions required to commercialize new energy technologies and introduce them into societies. The investigative studies will begin in the current fiscal to put into a complex the new energy industrial plants and the existing different industrial plants. There is a viewpoint that, when structuring specifically a business entity on coal liquefaction processes, some kind of complex is required as seen from the scale and economic performance of the business. Based on this viewpoint, the current fiscal year has carried out the studies placing the importance on technological feasibility for forming a complex with petroleum refining, iron and steel making, chemical and electric power generation industries. The model coal liquefaction plant uses the NEDOL method as the process, and establishes specifications for commercial size plants. The complex formation was discussed with the commercial scale of a coal liquefaction plant assumed to be 30,000 tons per day as the coal treatment quantity and 100,000 barrels per day as the product quantity converted into refined coal liquefied oil. As a result, a conclusion was drawn that, when the complex formation has been done successfully, an attractive business pattern may be formed although some problems may exist. (NEDO)

    Identifying the energy demand system as a total system covering from energy generation to the ultimate utilization, a quantitative and theoretical analysis method was developed in achieving selection and development of long-term strategy of Japan for 50 years from about 1975 to about 2025. Development was made on a supply estimation model by using the system dynamics method, that includes international fluctuation factors in primary energy supply structure and time-based relevant elements. Improvements were made in several occasions on the demand estimation model that includes movements of Japan's industrial structures and nation's needs for living, and fluctuation factors of population configuration. Development and improvement were made on the energy flow model to link the supply side with the demand side and analyze the energy flow. In addition, efforts were made on arranging data for inputting these models (data collection, putting them in order, and processing). These models are now in the phase of practical use, and three models have also been nearly completed. Quantitative analysis will be possible if arranging the input database is continued. (NEDO)

    This project is aimed at promotion of effective utilization of unutilized resources by transforming histidine-containing peptide (anserine), enzymatically hydrolyzed muscle protein present in lean salmon swimming off the Sanriku District in the spawning season, into functional peptide. A reactor system, comprising an enzyme-immobilized column and rotary bioreactor, is investigated to efficiently produce peptide by enzymatically hydrolyzing the water-insoluble muscle protein. Anserine is isolated by ethanol extraction, ion-exchanging and partition chromatography. The TPTZ and ABTS methods are developed for speeding up measurement of the antioxidant activity. The salmon muscle protein is hydrolyzed by 3 types of enzymes, to measure the free radical erasing activity by the ABTS method. The enzymatically hydrolyzed protein is fractionated by gel permeation chromatography. The fractions having a molecular weight of 10,000 or less show strong antioxidant activity. The hydrolyzed protein shows improved activity by the iron rhodanide method when it has histidine at the center of tripeptide, and strong radical erasing function when it has thyrosine or tryptophan at the carboxyl terminal.

    The geothermal district is characterized by distributions of high temperature and hot water. The beds and rocks in these areas are characteristically altered by these conditions. It is an object of this research and development project to clarify how properties of the beds and rocks in these areas, exposed to the characteristic physicochemical conditions, differ from properties of those in other areas. There are may rock properties. In this project, the studied properties are centered by those used for physical exploitation (or geophysical methods), e.g., electrical properties (electrical exploitation), magnetic properties (magnetic exploitation), and thermal conductivity (measurement of heat flow rates and geothermal gradients). The FY 1974 project covers pigeonholing the basic data, establishment of the experimental procedures, and measurement of water quality characteristics and temperature distributions (geothermal temperature gradients) at the test site. This paper reports the results categorized by (I) measurement of rock resistivity and effects on moisture content on this property, (II) properties of water in the geothermal district (Yahata-daira District), and (III) relationships between rock thermal conductivity and other properties.

    The oxygen electrode is important as the base electrode for water electrolysis and fuel cell, but to move it, overvoltage (activated energy) in addition to equilibrium voltage is necessary, which leads to the lowering of energy efficiency. By forming the active spot by ion implantation, the lowering of overvoltage was studied. The implantation of Ru{sup +} ion in Ruthenium dioxide thin film electrode reduced the oxygen generating overvoltage by 15-20mV. Even in the oxygen reduction, activity was also increased. The chemical composition of thin film does not change by ion implantation. The increase in activity is based on a physical change which is called the surface defect formation. The layer of ion implantation is composed of microcrystals, which is thought to contribute to the formation of any active spot. Ions were implanted in Pt electrode as a practical use material, and even in the oxygen reduction of Pt, a possibility of heightening activity by ion implantation was admitted even in the oxygen reduction of Pt. The generation of high activity oxygen by ion plantation and development of oxygen reduction electrode were established as one method as a rule. (NEDO)

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

    For the purpose of developing photonic sensors capable of ultrawide-range, ultrahigh-sensitivity, and high-speed processing, studies are conducted about organic nonlinear optical crystals. DAST (4-dimethylamino-N-methyl-4-stilbazolium p-toluenesulfonate) is taken up, which is an organic pigment capable of nonlinear optical performance superior to that of lithium niobate. In the research on {pi}-conjugate systems of DAST, more than 20 kinds of novel cations are synthesized, and some molecular species are found to be superior to DAST in performance. An etching technique is contrived, applicable to the processing of optical waveguides of DAST which is soluble in water or organic solvents, and waveguides of the multiple or single mode are manufactured. In the effort to make DAST crystals larger in size and higher in quality, a new crystallization method is employed, and a crystal larger than 15 times 15 times 2mm{sup 3} and equipped with a very flat surface is obtained. Furthermore, a DAST-aided electric field sensor is built, capable of detecting a high-frequency field of 60GH. To assist the designing and synthesizing of novel chemicals, the dipole moment and others are calculated for monomolecular DAST. (NEDO)

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

    A survey was conducted of a demonstration plant for developing the technology of integrated coal gasification combined cycle power generation. In fiscal 1994, based on the studies of pilot plant operation conducted up to the preceding fiscal year and on the studies of a demonstration plant (conceptual design of a demonstration plant), systems were examined for still higher performance and economical efficiency. For optimizing the heat source for pulverized coal drying air, an extracted air heat utilizing system was adopted, excellent in performance (approximately 0.5% improvement in absolute value) and in economical efficiency. For reducing the consumption of inert gas for the fluidized bed desulfurization facility, an approximately 30% reduction was found to be possible dependent on gas regeneration conditions in the regeneration tower. For performance improvement with the combined cycle equipment placed under a partial load, the generating-end efficiency was improved approximately 0.2% when only SGC (syngas cooler) was loaded 80% or less and kept at a constant pressure. Studies were also made about how to maintain a constant output with the equipment exposed to air temperature changes. (NEDO)

    Research and development efforts are exerted to produce advanced dental materials equipped with such functions as plaque reduction, bactericidal effect, and early formation of hydroxyapatite (HAP). In the study of fluorine ion implantation for plaque reduction, it is found that in a specimen implanted with fluorine ions the adhesion of carius streptococci is reduced to 1/3-1/10 for the achievement of remarkable improvement. In particular, carious streptococcus multiplication is suppressed when the metal shield layer is replaced with a titanium mesh. For the realization of a thin film formation method for osteoblast multiplication through reforming the material surface in the study of bone-forming dental materials, film formation conditions under which a P/Ca rate which is quite near that of ameloblast are achieved by use of a high frequency magnetron sputtering device. A titanium plate coated with a thus-formed film is annealed for a great increase in its wet contact angle, and then adhesion of bacteria is reduced and an osteoblast multiplication rate is increased by 20% or more, as compared with the case of no treatment in a petri dish.

    This study has begun in fiscal 1973 under a five year plan with an objective to elucidate origin and maintenance of reservoirs of geothermal fluids. To achieve the objective, estimation was made on the systems of infiltration, storage and gushing of the fluids, particularly on infiltration areas. In the hydraulic flow rate study, observation was carried out in the Onikubi area on amount of rainfall, air pressures, temperatures, electric conductivity, and pH, and in ten fluid sources on flow rates, temperatures and pH. Flow rate observation was started at three rivers. In the Kuju area, flow rate observation was started on four fluid sources. Observations were started on temperatures, electric conductivity, flow rates, amount of rainfall by using the Takenoyu geothermal steal wells, and on amount of rainfall in the Teraono and Hacchobara areas. In the study of isotopic geology, site analyses and water collection were carried out in the Kuju area for underground water in six locations, hot spring water in seven locations, and 17 test samples from two geothermal wells. As a study on reservoirs, observation was started in the southern Hachimantai area on measurement of ground fluctuation in association with steam collection. In parallel, fracture survey and gravity measurement were carried out. In order to investigate transformed geology, analytic samples were collected from 12 survey wells in the Onikubi area. A spinner flow mater was tested in that area. (NEDO)

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

    This paper describes the achievements at the Government Industrial Development Laboratory, Hokkaido in the Sunshine Project in fiscal 1990. Surveys were carried on different catalytic activities for co-liquefaction of various types of coals. The Ru system was found preferable in acquiring fatty family products of low boiling points. Reactions of co-liquefaction constituents do not progress independently, but have positive interaction. Adding Ru is effective in accelerating hydrogenation of condensed aromatic rings and hydrogenation of cleaving nucleus, but in view of the hydrogenating decomposition capability, the Mo-system may be better. In a liquefaction plant test, diesel oil was manufactured by reforming and improving the Yallourn coal light oil. However, the oxygen content was too high, aggravating the temperature distribution control in catalyst bed, and not having achieved the intended denitrification rate. Discussions were given on co-liquefaction of the depressurization residues of Cold Lake (CLVB[vacuum bottom])/Athabasca (ATVB) and Battle River coal. The CLCVB and ATVB were turned into lower molecules easily through hydrogenation treatment. The reaction characteristics reflected the characteristics of medium oil. Depolymerization of coal has progressed faster in ATVB. In the study on the engineering property values, discussions were given on behavior of solid particles in a bubble column, and gas hold-up of slurry. (NEDO)

    Although introduction of Joint Implementation (JI) and Clean Development Mechanism (CDM) have been adopted in the COP3, the details of how to set up the baseline for calculating the emission reduction amounts have not been established. This survey/research project has sorted out various concept menus for setting the baseline, verify each menu, and positively propose the methodology in an international arena, in which merits and demerits involved in simplified approaches, which try to simplify the works for setting the baseline, are analyzed, and their effectiveness is investigated. At the same time, both FCCC AIJ and NEDO AIJ projects are analyzed, to understand characteristics of baseline-setting method adopted by each project. There are many project types, to which direct application of any simplified approach is difficult. It is therefore realistic to analyze the situations case by case for the time being, and pursue for possibility of standardization of the baseline-setting methods after sufficient experience and data are accumulated to allow classification of the projects by common features.

    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.

    This promotion project on the cooperative research aims to efficiently extract and recover valuable metals (gold, silver, copper, rare metal, etc.) including in large quantity in tailings of ores in the Republic of Kazakhstan. In FY 1995, conducted were the field survey, support study in Japan, acceptance of researchers from Kazakhstan, conceptual design of pilot plant, etc. The ore/mineral for Cu is mainly an alteration ore of chalcopyrite. Au and Ag are low grade and unknown, and the main gangue mineral is pyrite. The low grade ore (waste/much) of the Nikolayevska mine has a tendency to leaching at normal temperature, but the ore of mostly chalcopyrite such as tailings from each place has difficulty in leaching. It gets leaching by increasing temperature. The more the temperature rises, the more conspicuous the reaction becomes. Further, chalcopyrite is leached with priority over pyrite. From the result, a technical potentiality was obtained of leaching of low grade chalcopyrite in tailings mostly of pyrite. The existence of Thiobacillus ferrooxidans was confirmed. As to the recovery method for Au and Ag, CIC is studied. The process of waste/much is solvent extraction, electrowinning study and leaching, and that of tailings is bacteria leaching and leaching study. (NEDO)

    This paper describes the achievements in the Sunshine Project in fiscal 1992 in studies on improving the efficiency of coal gasification. Three kinds of coals were gasified under the atmosphere of hydrogen, He or CO2 by using the TPR method. The sulfur removing rate varies depending on coals even under the same reaction atmosphere, and so does the degree of influence of the atmospheric gases depending on coals. Very little effect of the atmospheric gases was found on the sulfur removing rate in Taiheiyo and Wandoan coals. While Tatung coal presents the same removing rate under the atmosphere of He and CO2, it shows 1.8 times greater removing rate under the hydrogen atmosphere. Generation patterns for H{sub 2}S and COS also vary depending on coal types and atmospheric gases. Inorganic sulfur shows the same behavior in the reaction process regardless of coal type and atmosphere, but organic sulfur behaves differently. The sulfur removing rate is determined by how easily the organic sulfur can be removed, which attributes to the difference in kinds and structures of organic sulfur compounds in the coal, together with the gas generation patterns. In order to discuss gasification of char, investigations were performed on effects of coal types and heat treatment temperatures, with regard to the gasification characteristics that can be estimated from the industrial and element analyses.

    The research is conducted in cooperation with Industrial Technology Development Institute of the Philippines, and aims to solve water related problems such as unstable water supply and water quality pollution though developing a waste water treatment and recycling system which is easy to operate and maintain, low in cost, and usable in the Philippines. Fiscal 1998 is the second year of the project. Statistics are studied about the load that each industrial branch imposes on water for its pollution, and it is found that food manufacturers, paper pulp mills, and fiber dyeing plants are heavily responsible for water pollution. A method consisting of single-tower UASB anaerobic treatment and activated sludge treatment is applied as a water treatment process to Ram Food Products Corporation, and its optimization is studied. A removal rate 60% is achieved after a 12-hour treatment period at a COD (chemical oxygen demand) rate of 8g/liter/day. A method consisting of coagulating sedimentation and activated sludge treatment is applied to the waste water from a Solid Mill Corporation dyeing plant, when it is found that the water after ultimate treatment is almost colorless and that COD is 76mg/liter and BOD (biological oxygen demand) 13mg/liter, and these suggest that the waste water is recyclable. Since it is low in COD removing rate, the application of anaerobic treatment to high-concentration water after washing is not appropriate. (NEDO)

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

    It is important for geothermal energy to develop and utilize it in a rational manner. To achieve the objective, hot water systems must be studied comprehensively and elucidated from the standpoint of the systems as a whole. The present study, standing on this viewpoint, is intended to elucidate hot water systems and establish a survey method thereon. Fiscal 1973 has selected four areas (northern Hachimantai, southern Hachimantai, Onikubi and Kuju areas) as the model study fields, and used as the main field the Onikubi area, which clearly shows the structural catchment basin. Studies were performed in this area on hydraulic hot flow rates, isotopic geology, and reservoirs. In the hydraulic hot flow rate study, the amount of rainfall, amount of flowing water, and amount of hot spring water flow-out were observed continually. In the isotopic geology study, hydrogen in hot spring water and underground water, and composition of oxygen isotope were analyzed. Estimation was made from the result thereof on water balance, heat balance, and underground residence time. In the study of reservoirs, measurements were performed inside the wells, and estimation was made on locations and sizes of the reservoirs by surveying distribution of transformed minerals and cracks.

    Studies are conducted about anthropometry using a computer mannequin for assessing the compatibility of virtual commodities and environments, fabricated by CAD (computer-aided design) or the like, with human beings, and the fiscal 1999 achievements are compiled. In the study of multidimensional equations of correlation for shape estimation, calculation of basic human model dimensions using 43 measurements has become feasible. For the construction of a human model using a computer mannequin, joint positions and distances between joints have to be determined using data which are measurements that cover human model surfaces. Such necessitates a study of shape estimating algorithm, and a basic physique calculation module and a shape estimation module have been developed. Verification is conducted using a computer mannequin, and it is found that much information is quantitatively determined prior to the manufacture of real goods, the said information involving the mechanism of a chair and the behavior of a human being in it, and the relations of the human behavior with peripheral equipment.

    This paper describes development of structural materials for municipal refuse incinerators, in particular, high- temperature corrosion-resistant ceramics for inner walls. Unlike boiler tubes of which inner walls are cooled by water or water vapor, refractory for inner walls is subjected to high-temperature flame over 1000degC, corrosive gases such as HCl and SO2. and low-melting point corrosive dust such as chloride, sulfate and oxide under strong corrosive environment. Experiment was made on 14 kinds of ceramics including commercially available oxide system, non-oxide system and refractory system ceramics. Except graphite system ones, every ceramics, in particular, Al2O3, ZrO2, B4C-doped SiC and CVD-SiO showed superior properties. Commercially available ceramics, in particular, non-oxide system ones are very expensive. Since inner wall materials for refuse incinerators are heat-/corrosion-resistant consumption articles, it is suggested that improvement of reasonable oxide system ceramics or conventional SiC system ones is better. 73 refs., 89 figs., 39 tabs.

    Research was made on improvement of the wettability and boiling heat transfer characteristics of a photocatalyst wall. Measurement experiment of the wettability was made for anatase type titan oxide-coated Al, SUS and Pb plates, rutil type titan oxide-flame coated SUS plate, raw plate, and oxide-plasma coated titan plate. In the ground experiment, the contact angles of distilled water and oil on specimen surfaces were measured. In the microgravity experiment, falling droplet images were recorded by using the facility of Japan Microgravity Center (JAMIC). For obtaining the effect of radioactive emission, UV irradiation, {gamma} ray and neutron beam irradiation by nuclear reactor, and {gamma} ray irradiation by Co-60 were carried out. As the experiment result, the rutil type titan oxide-flame coated SUS plate, nonconductor-coated titan plate, and zircaloy plate showed large improvement of the wettability by {gamma} ray irradiation with Co-60. It was also confirmed that in particular, titan shows the large effect of radioactive emission, and the wettability deteriorates rapidly after {gamma} ray irradiation. (NEDO)

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

    The current fiscal year has surveyed and studied to have coal liquefying plants and the different existing industrial plants put into a complex. When structuring specifically the commercialization of the coal liquefaction process, some kind of complex formation is required from its business size and economic performance. From this viewpoint, the current fiscal year has performed discussions with economic performance as an additional item on forming a complex with (1) petroleum refining industry, (2) iron and steel making industry, (3) chemical industry, and (4) electric power generating industry. Investigations were also carried out on the feasibility of systems thereof and the technological problems therein. In the subject (1), if coal liquefied oil is introduced into a petroleum refining process, and both oils can be mixed, construction cost of the coal liquefaction plant and the oil cost per barrel may be decreased. In the subject (2), forming a complex of a converter integrated steel mill having a crude ore production scale of 600,000 tons a year with a coal liquefaction plant having a scale of 30,000 tons a day will present problems in the balance of facility size and quantity. In the subject (3), producing chemicals as by-products as a result of complex formation will enhance the economic performance of the coal liquefaction plant. In the subject (4), a complex formed plant is more advantageous in load variation than ordinary power plants. (NEDO)

    For the purpose of realizing `the affluence` sought in the Japanese economic society, the supply and preparation of products, service and environments friendly to human beings seem to be important. In the future, the development of products which are fully considered also of aged and handicapped people is more expected than the conventional manufacturing of products added with value. Especially in accordance with the rapid aging, from a viewpoint that the lowering of physical functions caused by aging has an exactly close relation with the response to products and the environment, development of the database of physical functions for the aged which is useful for the design is urgently promoted. First, the data to be supplied for database were selected. As to the selection method, the data required for database were defined by collection/analysis of the existing data, examination of the needs of enterprise designers, and analysis of daily activities. In the study of the database, the structure by which data can be effectively supplied was studied and verified by pilot database for extraction of the subjects and solution to the problems. 6 refs., 57 figs., 26 tabs.

    Improvement of an antibacterial activity is one of the issues in modification of artificial teeth for an aged society. Study was made on improvement technique of an antibacterial activity with Ag ion as secondary corrosion measures. Partial gaps of dental materials themselves and gaps between materials and peripheral tissues causes bad breath or bad teeth through propagation of disease germs. Ag ion is harmless and has an antibacterial activity for bio-tissues from a macro-viewpoint, however, only corrosion germ causing bad teeth in mouths should be sterilized by controlling an elution rate of Ag properly. The antibacterial activity was controlled by controlling Ag ion implantation depth and rate, and Ag elution rate for dental materials. Experiment was made on an IMZ twinplus specimen implanted with Ag ion and an Ag thin film-coated specimen using beagle dog in comparison with an unmodified specimen. As a result, the very favorable antibacterial activity was obtained. Ag ion is effective for prevention of endogenous infectious disease due to mouth germs in dental surgery. 3 refs., 47 figs., 10 tabs.

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

    Described herein are the FY 1988 results of development of corrosion-resistant ceramic materials for garbage incinerators. Residue released when porcelain stocks are collected is selected as the inexpensive stock for SiO{sub 2}-Al{sub 2}O{sub 3}-based refractory materials. It is incorporated with carbon black and reduced at 1,200 to 1,500 degrees C in a nitrogen atmosphere. Synthesis of the target Si-Al-C-N-O-based compound succeeds in the presence of a solid catalyst, but it is a fine powder, and hence that of the massive compound fails. The commercial ceramic materials and new refractory materials, made on a trial basis, are evaluated for their resistance to corrosion using fry ashes collected from a commercial incinerator. These ashes are higher in melting point, more viscous, holding a larger quantity of attached slag and more corrosive than synthetic ashes. These materials are corroded acceleratedly as temperature increases to 1,200 degrees C or higher, more noted with the ceramic materials than with the refractory materials. Oxidation and melting characteristics of the molten slag affect corrosion of some materials. Use of the graphite-based material shall be limited to a section below the slag surface, where graphite is oxidized to a smaller extent. The MgO-based material is promising. The Al{sub 2}O{sub 3}-Cr{sub 2}O{sub 3}-based material is more promising than any other material developed in this study. Their bending strength before and after the corrosion test is measured at normal temperature to 1,700 degrees C, to investigate their deterioration by high temperature and corrosion. (NEDO)

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

    The research cooperation project for fuel cell utilization/district power generation system is conducted under the research cooperation agreement between NEDO and Electricity Generating Authority of Thailand (EGAT), to demonstrate a 50 kW pilot plant constructed at EGAT's Bang Pakong power station. The fuel cell reforms self-spouted natural gas into H{sub 2} as the fuel. It has produced a total power of 341,921 kWh under the conditions of cumulative operating time: 8,115.4 hours, longest continuous operating time: 1,100 hours, service factor: 89.64%, load ratio: 86.13% and system utilization factor: 77.20%. The fuel technique will be acceptable for Thailand, if it is economically competitive. The project for producing raw palm oil is for Malaysia. The facilities introduced and tested for the new process are a continuous steam-heated fruit remover, fiber/nut separator, and shell cutter. The new process is evaluated to produce higher-quality raw palm oil in higher yield while consuming less energy. The new process, whose steps are automated, saves operating cost, and suitable for Malaysia which is suffering shortage of manpower. (NEDO)

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

    To clarify the material properties of apatite compounds, the synthesis method, and the evaluation of physical properties of material and elementary technology were investigated. For the study on synthesis and crystal growth, a method of precipitating calcium phosphate on the surface of metal was investigated by means of relatively mild electrolytic method using liquid phase system. A new molding method of Ca defective apatite was established. Composite similar to vital bone was prepared by means of a new low-temperature sintering. For the study on chemical properties, from the model experiments, it was found that the self-organizing phenomenon, which is observed in the composite of apatite and collagen, happened between the organic single molecular film and crystal of apatite. For the study on evaluation of physical properties and elementary technology, the surface and interface of ceramics such as apatite were investigated by means of spectroscopy, the electronic state was analyzed by the quantum chemical calculation, and the crystalline structure was analyzed using X-ray equipment. 270 refs., 102 figs., 10 tabs.

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

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

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

    With an objective of putting into practical use the wavelength multiplex recording system applied with the PHB phenomenon, research and development has been performed on material systems making high quality hole production possible at high sensitivity and high density. This paper summarizes the achievements in fiscal 1989. In the discussion of PHB materials, measurements were performed on the triple state of zinc, magnesium, copper and iron complexes of tetra-phenyl porphin and the triple state spectra by using the flash decomposition method in order to develop new photo-gate type material systems. Correlation was discovered between the free energy change in the reaction and the PHB reactivity from the result of the experiments, whereas important findings were obtained for designing the photo-gate type PHB material systems. In the discussion of the wavelength multiplex recording, an optical system was designed and fabricated to perform scanning and detection on sample surface by using laser beam squeezed to a diameter of 100 {mu} m. Discussions were given on the wavelength multiplex recording, position multiplex recording, and high-speed recording using this optical system. As a result, position multiplex holes were produced successfully by using the laser beam squeezed to a diameter of 100 {mu} m on four different positions on the sample surface, when the tetra phenylporphin derivative was used.

    In the research cooperation promotion projects having been carried out, the R and D of an overall recovery system have been conducted which recovers effectively and systematically valuable resources such as magnesium, bromine and boron including in brine made after the salt manufacturing in the coastal region in Mexico. In this project, as the research on the distilling process needed for commercialization of the system to recover valuable resources from the brine, Japan has been collecting information on various distilling processes and solar pond systems and studying a distilling process appropriate to the site jointly with Mexico. As a result, a seawater desalination process which combined the solar pond using solar energy and the evaporation method was recommended as a low-priced distilling method. Moreover, it was indicated that the solar still method for condensing/recovering the evaporated water of the Guerrero Negro salt pan is also less influential in the salt manufacturing process and is viable as a most economical distilling process by studying the structural design and operational method of more efficient solar stills

    Solar technology and energy conservation technology (through retrofitting) which can be introduced into existing buildings are evaluated for their effect and economic efficiency. Studied are technologies verified to be technically feasible at the current stage, introducible into existing buildings without major modification, low in introduction cost, and high in energy conservation effect. How retrofitting technology should be in Japan is discussed. In Japan where demand for heat is smaller than in Europe or America and building service life is shorter, conditions to meet for efficient cost recovery are quite severe. Suitable measures to enhance cost recovery include use of multiple panels of low-radiation glass and light modulators for windows and use of collecting technologies such as solar systems for hot water supply and air solar collectors. Use of a transparent insulator is also recommended. Japanese houses demand repair and reconstruction very often, which helps cost recovery. Dependence on locality is extensive, and this causes difference in solar system application. Since it is high in temperature and humidity in summer in Japan, there is a great need for environmental comfort, and therefore not only energy conservation but also comfortable air-conditioning is important.

    For the development of working conditions fit for aged people and devices for them to operate, their visual function and behavioral characteristics are measured and analyzed. In the study of visual functions, 50 people from local cities and regions and another 50 from Osaka and its neighboring cities are subjected to measurement regarding visual acuity required in daily life, color discrimination, dark adaptation, glare, and the like. In the study of performing characteristics, 500 people are subjected to measurement regarding the scope of movement of upper limbs, their reach, and skillfulness with which the people can move fingers. When brightness, luminance, and contrast are caused to change relative to letters and background, aging is found to exert a great influence on the ease of reading, dark adaptation, and glare. As for the upper limb work range and reachability and the skillfulness in finger movement, it is found that aging narrows down the tolerant work area, lowers the working pace, and greatly affects skillfulness depending on the device operating method, all these disclosing actualities of difference attributable to age and sex. Concerning the device operating position and the ease of device operating force application, new measuring and evaluating methods are worked out, and correlations between the contents of operation and the operating position are seized.

    This paper reports the research of coal liquefying technologies in the Sunshine Project in fiscal 1988. The research was performed with importance placed on the fundamentals of coal liquefaction and high value added compounds. Production of n-paraffin in the liquefying reaction occurs from reduction of acidic ester, and this ester structure contributes to cross-linking of aromatic rings. Most of the aromatic rings in coal has long side chains. A hypothesis was assumed that these chains have been produced from reaction of lignin in plants with fatty acid or alcohol. The hypothesis was verified from a synthesizing reaction by model substances. This could be said an initial reaction model for coalification. In order to verify de-alkylating reaction of the liquefied oil, model substances were used to investigate the products. Benzene having long alkyl side chains have the alkyl group dissociated, and on the other hand cyclization progressed producing naphthalene. Melting performance during coking is attributed to a great amount of solvent soluble low molecular constituents contained in coal. These constituents are contained in close contact in a net-like structure, which is loosened only by heating extraction, and extracted. They have no hydrogen donating performance. (NEDO)

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

    This paper describes 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)

    The trend of technology development, problems harbored therein, trend of the market, and the like were investigated for supporting the development of technologies for the mass production and commercialization of solar-grade silicon materials. Concerning the future of production enhancement and cost reduction in the manufacture of polycrystalline silicon solar cells, studies were made from the technological viewpoint. The results are shown below. It is estimated that approximately 4,500 tons of material silicon will be necessary in 2005 and 6,500-10,700 tons in 2010. Since the melting purification method of NEDO (New Energy and Industrial Technology Development Organization) now under development step by step toward commercialization as well as the conventional source will provide the necessary amount of material silicon, it is inferred that the development of solar cells will go on without any restraint originating in the semiconductor industry. With the commercialization of the technologies so far developed and the development/commercialization of the fast-acting high-performance solar cell technology, probabilities are high that the polycrystalline silicon solar cell manufacturing cost in 2010 will be as low as to be on the 100 yen/W (93-118 yen/W) level which is the level now held up as the goal.

    As for fuel cells, which are expected as a new clean energy, the R and D are being proceeded with in various fields of the world, but the standardization has not been made both in Japan and abroad. In Japan, the situation is that the information on technical terms, indication method, performance test method, and environment/safety test methods of the phosphorous acid fuel cell power generation is publicly spread. In relation to the international promotion of fuel cells to be predicted, it is necessary to internationally standardize cells themselves which are a key component of fuel cell power generation facilities. Phosphorous acid fuel cells are expected of the earliest commercialization of all, but the common test method to evaluate life characteristics of the cell stack has not been established yet. In the R and D, for the purpose of internationally standardizing test methods to evaluate life characteristics of the cell stack, a study on the acceleration life test method of phosphoric acid fuel cells was conducted in terms of the technical trend, data, standard, etc. A plan was prepared on general rules of the method to test acceleration life at the cell reaction part of the small cell, and activities also were started for setting up a technical committee for the fuel cell power system in President`s Advisory Committee on Future Technology. 29 figs., 20 tabs.

    This paper describes the achievements in fiscal 1999 on researching and developing standard substances related to polymers. Investigations were performed on polystyrene with average molecular weights of 300 to 2,000 being the standard polymeric substance as the primary subject, and polycarbonate with molecular weight of about 300,000 as the secondary subject. Development was executed on the fundamental technologies related to chromatographic conditions for separation to acquire polymers without molecular weight distribution or with very little distribution (single dispersion), and sampling conditions for the sampling chromatography. Uniform polymers were used as the primary calibration standard substance to have developed the fundamental method and the fundamental conditions to value exactly the average molecular weight values such as in the single dispersion test. Polyvinyl chloride (PVC) was taken up as the valuing material as a polymeric material with less secular change being the indispensable element as the standard substance, and capable of being stably supplied. Round robin tests were performed by 16 testing organizations on the tensile elasticity specified in ISO10350 in accordance with the international standard guide 35 to have valued the standard substances. Variance in property values of PVC sheets was analyzed, and the standard deviation was verified. (NEDO)

    As for the collection of sensible heat, 1/3 of blast-furnace slag is treated to the purpose at the Teesside Technology Centre, Britain, but none is collected in the latter half of tapping in case there is so much slag that cooling cannot be done in time. In the case of a large blast furnace, some measures have to be contrived because molten iron comes out of the furnace intermittently. In Germany, the heat collection rate is as low as 3%, with no effort made at heat collection. In North America, desire to develop such a technology is not strong. A visit was made to the Institute of Ocean Sciences, Canada, in relation to the concept of using steel slag as a eutrophic source for marine photo-plankton. A large-scale long-term test is under way for examining the relationship between global warming and ocean current circulation. There are possibilities that Japan will enter into the project for a joint study, for example, of heavy metal elution from slag though the test fails to name slag as the direct object of study. Not only for Canada but also for any other country who faces the sea, it may be a meaningful national policy to inject some active ingredients into the sea for an increase in living marine resources. Greece is engaged in the ocean dumping of nickel slag on an experimental basis but, in view of the purpose of the experiment, Japan will not be a participant in the project. (NEDO)

    Thermal efficiency enhancing system technology for existing thermal power plants is studied jointly with Indonesia to achieve energy conservation and power generation cost reduction and serve for suppressing CO2 emission. Site investigations were carried out for the study on enhancing thermal efficiency in component devices, including improvements in a device to rinse small pipes in condensers and in materials used in air preheaters, as well as for heat management and efficient operation of the plants. Indonesian engineers were received to develop device designing and thermal efficiency controlling programs, and for technical guidance. Site seminars were held to proliferate the achievements. Under the trend of increasing electric power demand, Indonesia is apt to place first priority on stabilized operation of power plants, with the efforts of thermal efficiency management staying behind partly due to fossil fuel price being low. The present project has made it possible to utilize hereafter the result of the rough design on improving the thermal efficiency in existing thermal power plants as has been done under the present project. Receiving the researchers and holding the site seminars also helped transfer the technologies on the thermal efficiency improving processes, and device maintenance and management methods.

    With an objective of creating ultra-high density organic photo recording elements for photon mode recording and rewritable wavelength multiplex recording by utilizing control of association status of photochromic compound, research and development has been performed. This paper summarizes the achievements in fiscal 1989. In developing the materials, verification was made on effectiveness of the newly structured positive polarity model. The method was used to attempt synthesis of four kinds of new spiropyrane, among which it was discovered that BSP1822 forms J-association complex in the long wavelength region. In the thin film forming technology, the J-association complex of BSP1822 was stabilized successfully in the film mixed with bi-molecular film forming material. In order to develop a technology to form dry photochromic thin films, an organic molecular beam epitaxial device and a thin film structure analyzer were introduced. In the elucidation and research on fundamental properties, discussions were given on properties of the SP1822LB film revealed by the steady-state light and laser pulse light. Furthermore, the molecular orientation of the SP1801 on the air-water interface was investigated, and molecular models on the air-water interface were considered. (NEDO)

    As one of the efforts to establish national reference materials at an accelerated pace in a concentrated manner, a comprehensive survey was conducted on reference materials for polymers, and research and research was conducted for the development of such. In the comprehensive survey, investigations were made into the actual use of reference materials for polymers and their management at private-sector enterprises and public research institutes in Japan and at research bodies in the U.S. and Canada. In the development of reference materials for polymers, a procedure was contrived for synthesizing monodisperse oligostyrene specimens, polymerization was carried out using an improved synthetic method, and molecular weight distribution was analyzed. Using a homogeneous oligostyrene reference material for calibration, the mean molecular weight of an oligostyrene reference material was accurately evaluated by size-excluded chromatography. In the case of a specimen with its mean molecular weight not more than 1,000, the result exhibited excellent agreement with what supercritical fluid chromatography indicated. In the development of reference materials for characteristics evaluation, this in relation to methods for evaluating thermomechanical characteristics of plastics, efforts were made to develop reference materials for evaluating dynamic viscosity/elasticity of solid plastics.

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

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

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

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

    The following were selected as themes necessary and important for the safety of the forthcoming hydrogen energy system, based on the fiscal 1974 document survey result, and the fiscal 1975 research results. First as for low- temperature storage of hydrogen, since safe discharge of hydrogen gas generated in a storage tank is important, gas motor discharging usually used for such transport tanks as tank lorry, and burn bond discharging suitable for discharge of a large amount of hydrogen were selected as test items. Next as for storage and transport of low-temperature hydrogen such as liquid hydrogen, a low-temperature control valve to control the amount of liquid hydrogen for transport was selected as a test item. Under the assumption of the model tests on the above 3 items in fiscal 1976, various studies and trial designs were made on concrete test equipment. The test plans were also prepared for some ones among them. (NEDO)

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

From the 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)

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

    Tests and researches have been performed with the objectives to establish an evaluation technology for load leveling effect by using a small photovoltaic power generation system for residential use, to clarify the effectiveness of the system as a discrete power supply source through demonstration operation, and furthermore to achieve optimization of designs of the small photovoltaic power generation system for residential use. This paper summarizes the achievements in fiscal 1997. The current fiscal year has performed the continued collection of data of the demonstration operation, and analysis and evaluation on the photovoltaic power generation characteristics and the house load characteristics. According to the data analysis result for fiscals 1995 through 1997, it was shown that, although the photovoltaic power generation system for residential use does not contribute much to load leveling in a house, it contributes to load leveling in the distribution line on the whole or a case as large as a grid. In addition, according to the survey on users who have installed the photovoltaic power generation system, it was indicated that the consciousness of electric power and energy conservation has heightened. The capacity of a photovoltaic power generation system for residential use is 3 kW for a standard type of home, which can take care of more than 60% of the house load. It was concluded that, if a storage battery of small capacity is accommodated, the system is effective for reduction of momentary peak load, enhancement of the power quality, and supply of power at a disaster.

    The R and D project has been implemented for establishing, e.g., methods for growing oxide single crystals (e.g., lithium tantalate, LiTaO{sub 3}) to have the large and/or long products, technologies for polishing/cleaing the wafer products, and technologies for evaluating device performance. For solidifying growth and production technologies for lithium tantalate single crystals, pulling-up of the single crystal, 154 mm in body length and 12.9 kg, is succeeded by reducing temperature gradient at the crystal solid-liquid interface, increasing oxygen concentration, and improving the seed-sustaining system. Bright prospects have been obtained for the automated crystal pulling-up system, and high-precision control of crystal weight. For technologies for polishing/cleaning the wafers, the investigated cleaning methods include ELID polishing, mechanochemical polishing, and supersonic cleaning which uses two frequency bands of multi-supersonic and megasonic waves. For development of the technologies for evaluation/examination of the highly functional devices, the non-contact type method has been developed, which can measure the absolute level of SAW speed at a high speed and precision.

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

    The research and development project is conducted to develop new methods directly related to early discovery of potential cancer patients, and the FY 2000 results are reported. The FY 2000 efforts are directed to improvement of intra-Alu-PCR method as the superhigh-sensitivity quantitative method, almost established in the previous fiscal year, to have higher reliability and simplicity suitable for automatic diagnosis. It is concluded that (there is no difference of significance between normal persons and cancer patients in free DNA concentration in the blood, determined by the Boyle/intra-Alu-PCR method), but this method is confirmed to be useful for prognostic monitoring of the patients who have the marrow or peripheral vessel cell transplant. Detection of qualitative gene abnormality of DNA in the peripheral vessels is investigated using the K-ras, p53 gene. Certain results are obtained by the MSA method for the former, and by the newly introduced WAVE DNA fragment analysis system for the latter. However, there are still a number of problems to be solved before these methods are applicable to screening for general medical examinations. The research on the (analysis of gene abnormality of cancer itself) has made a notable progress. (NEDO)

    Demands are strong for lower-resistivity transparent conductive films formable at low temperatures (target substrate temperature of 100 degrees C) for the realization of higher-quality electronic equipment required in highly computerized society. The project aims to develop a system for complexation and amalgamation of high-density energy beams (multi-beam thin film formation) and to establish a technology of practical level ultrahigh quality transparent conductive film formation. For this purpose, a load lock system and a laser irradiation system are added to a device developed in the past. A high-quality ITO (indium-tin oxide) thin film is formed at a low temperature by deposition using oxygen cluster irradiation. During film formation using the laser aberration method, ultraviolet rays are applied to the substrate, and a low-resistivity film of 8.9 times 10{sup -5} ohm/cm is obtained on a substrate at 200 degrees C. This process is attributed to crystallization accelerated by ultraviolet rays and to an increase in carrier mobility. In a process of transparent conductive film formation under a complex beam, composed of a laser beam and oxygen cluster ion beam, to be excited for application to mass production, an ITO thin film is formed, with its resistivity extremely low at 10{sup -5} ohm/cm even at 100 degrees C.

    A prototype force control piston insertion device which does not need jigs is built for use on the assembly line. An extensive reduction in investment for automated facilities is expected to realize because jigs conventionally required for each size are dispensed with. For expanding the scope of force control application, the device is verified for serviceability by use of a 5-axis robot and a visual servo control technique. A combination of vibration control and tracking control is applied to an integrated simulation/experiment environment. For the processing of inner force sensor data, a pseudo contact point monitoring technique is used. A wire type tactile sensor is proposed, which has a flexible-structure moment detector in which a flexible beam like a piano wire is the probe. For the inspection of ICs (integrated circuits), a passive compliance unit and a force control based flexible inserter are fabricated, to be used for a reduction in the number of no-good contacts. Technologies of shock absorption aided by robot terminal device tactile sense and of virtual damper control for shortening the setting time are verified for their validity by use of the IC inspecting inserter.

    Efforts are exerted to make novel recyclable polymer alloys excellent in material characteristic and to develop a technology for processing them, for which liquid crystalline polymers equipped with a self-alignment capability are combined with thermoplastic resins. In the research on the alloying of polyethylene terephthalate (PET) and liquid crystal polymers (LCP), studies are conducted about inorganic nucleating additives, thermostabilizers, and mold releasing lubricants, and a success is attained in the manufacture of excellent alloyed pellets. In the injection molding of alloys of PET and LCP, a product is obtained, among those produced with the rate of LCP varied, which behaves excellently even at a high resin temperature of 285 degrees C. It is found about PET/LCP alloys that improvement is achieved with additional LCP in terms of the warpage temperature under load, bending property, strength, and dimensional stability upon exposure to heat. In the study of the response of LCP-diffused PET to a process demanding distortion, an injection-molded product containing 10-20% of LCP is found to exhibit excellent ductility. It is also found that PET/LCP alloys may be cut and machined easily and that therefore their crushing for the recycling purpose will be easy. (NEDO)

    The third conference (COP3) of the United Nations Framework Convention on Climate Change held in December 1997 in Kyoto has adopted the Kyoto mechanisms (the 'discharge right transaction', the 'joint implementation (JI)' among advanced countries, and the 'clean development mechanism (CDM)' applied to developing countries). The Kyoto mechanisms are intended to provide flexibility to the methods to achieve the greenhouse effect gas reduction targets established in the Kyoto Protocol. The Kyoto mechanisms are considered to be implemented even during the year 2000, whose details are scheduled to be decided at COP6. Since the advanced countries have established the targets for reduction of greenhouse effect gas emission, governments and research institutes are taking various approaches. In addition, since the targets for reduction of greenhouse effect gas emission have been established, discussions are indispensable on methodology to establish the quantity of discharge and absorption of greenhouse effect gases (the so-called base line) when no project exists, as required to calculate the discharge reduction quantity as a result of implementing the project. The present survey has held study meetings attended by learned people, and compiled the results of the discussions. (NEDO)

    The research and development project is implemented for development of the system which automatically switches off the power source for a standing-by appliance by analyzing life pattern in each home, in order to reduce consumed power during the stand-by period. The actual service conditions of appliances in each home are surveyed through the questionnaires and recording in the diary. The analysis results indicate that as high as 70% of those who are inquired take interest in energy saving, especially high among full-time housewives. The home electric appliances considered by many to wastefully consume power are functional-keeping types, e.g., (jar pots) and (toilet seats equipped with a washing function with warm water), and heating appliances, e.g., (hot carpets). The power consumption trends at each time in each home are measured and grasped by the aid of a tool with built-in personal computer, and the algorithm for predicting use of the appliances in each home is developed for each home, based on the analysis results. The prototype energy-saving adapter and centralized controller are developed, and subjected to various tests to develop the learning/controlling algorithms. The demonstration tests of the energy-saving adapter developed confirm that power consumption during the stand-by period can be reduced at least by 10%. (NEDO)

    Fine solder grains have been developed, spherical in shape, uniform in diameter, high in dimensional precision, and high in surface cleanliness, which are necessary for the establishment of next-generation technologies of flip chip bonding and ball grid array which are indispensable for high-density high-reliability packaging of electronic devices such as LSI (large scale integration). Results attained in fiscal 1998 are described. A pulse pressure aided orifice injection method was used. Monodispersed grains are prepared for the Pb-63Sn solder and Sn-3.5Ag lead-free solder. In the case of a 200{mu}m-large orifice, the grain diameter was controlled to fall in the range of 190-210{mu}m and the accuracy was not lower than {+-}6{mu}m. The main goal of this project has been accomplished now that these figures were attained without a sorting process and satisfy the most rigorous conditions currently proposed by the industrial circle involved. The flow of hot liquid out of the orifice and the splitting process of grains were clarified by thermal hydraulic analysis. It was found that grains split and fly not because of instability due to Rayleigh surface waves but because of their liberation from surface tension when equipped with critical kinetic energy.

    A Mukhaizna oil field remains to be exploited in Oman, with an estimated reserve of 2.4-billion barrels of very heavy oil with an API (American Petroleum Institute) specific gravity of 15.3. The viscosity of the oil is so high as to be over 100-thousand cP (at 15 degrees C). The extremely high viscosity causes its exploitable rate to be so low as 3%, and makes shipment by pipeline quite difficult. In this survey, a method using water emulsion is proposed for viscosity reduction, which aims to reduce the Mukhaizna crude oil viscosity to 200mm2/s or less. In an experiment using the water emulsion method, oil is mixed with water at a rate of 72 to 28 in a shearing mixer for the production of a water emulsion of crude oil. It is found that a certain degree of stability is acquired using a surface active agent available on the market. Using this emulsion method, the crude oil is converted into a power generator fuel with a heating value of 6,775kcal/kg. The crude oil-turned product is a fine fuel superior to Orimulsion which is a fuel of the same type in terms of viscosity, amount of ash, and vanadium concentration. (NEDO)

    With an objective to evaluate feasibility of practical use and economy of the coal hydrogasification technology (the ARCH process), survey and research have been performed. This paper summarizes the achievements in fiscal 1999. In the survey on the social acceptability, survey has been made on the future trend in the demand and supply and the price of LNG, LPG, and coal for hydrogasification. As a result, it was discovered that the price of LNG imported into Japan is determined as if linked with the crude oil price, and Saudi Arabia is the price leader of the LPG price. With respect to the survey on the possibility of international cooperation, surveys were conducted on the prospects of the long-term demand and supply in China, natural gas resources, and the demand and supply thereof. The feasibility study has estimated the product gas manufacturing cost after the process has been improved. In the trial calculation on the three-mode cost, it was discovered that, although the profit from byproducts is great, the BTX maximized mode causes the manufacturing cost to be higher by as much as 2 to 3 yen per Nm{sup 3} than that of other modes because of higher unit consumption in raw materials and higher construction cost.

    This paper reports the result in fiscal 1995 of the study on PLD (pulse laser deposition) thin film formation process having been made since 1993. In fiscal 1995, the effect of irradiation of excimer laser and YGA(SHG) on ablation of aggregates of N2, CH4, Ar, Kr and Xe, and the effect of time-delayed irradiation of YGA(SHG) and KrF excimer laser on ablation of N2 aggregate were studied aiming at exciting ablation by cryogenic aggregate alone. Experimental results by a newly developed multi-laser excitation experiment equipment are as follows. Ablation was not caused by KrF excimer laser irradiation, while caused by YGA(SHG) irradiation. Ablation was caused by 1mm thick N2 or CH4 aggregate alone. Kr target was the most promising among rare gas solid targets expected as seed of ablation occurrence. Multi-irradiation showed a different ablation behavior as compared with single YGA(SHG) irradiation, and in some cases, multi-irradiation not increased scattering of particles. Time-delayed multi- irradiation (YGA(SHG) excitation after excimer excitation) was effective. 23 figs., 4 tabs.

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

    An investigative research was conducted on the means of reducing fuel consumption of motor vehicles and reducing greenhouse effect gases, by making octane boosters for gasoline through the use of alcohol derived from biomass feedstock. As a result of the investigation, the following proposals were made. In present gasoline-fueled motor vehicles, an increase in the octane number by 5 will allow a higher compression by 1, thereby reducing fuel consumption by 2.5% during running. The suitable octane boosters are MTBE (methyl tertiary butylether) and ETBE (ethyl tertiary butylether) both of which can be produced from either methanol or ethanol derived from biomass feedstock. Blending regular gasoline with an octane number of 90 and either MTBE or ETBE by 18% may make gasoline having an octane number of 95, leading to a reduction of carbon dioxide emission by 4.8% and 6.8% respectively. The amount of alcohol needed for these octane boosters is 2.2 megatons of methanol per year for MTBE production and 2.7 megatons of ethanol per year for ETBE; this requires 12 plants nationwide for producing the octane boosters at 0.5 megatons per year; and, in view of the cost of transportation, alcohol producing plants are desirably located near the octane booster producing plants.

    Complex beam epitaxy (CxBE) process was proposed and demonstrated as new deposition process of multi-element oxide thin films. This process radiates excimer laser onto a metal complex target of ethylenediamine-tetraacetate complex under reduced pressure oxygen atmosphere condition in a reaction vessel to supply raw material onto a heated substrate. This process allowed deposition of YBCO123 phase hetero-epitaxial film onto a single-crystalline SrTiO3 substrate. This process was proved to be promising through study on crystal orientation, composition transcription and surface smoothness of the obtained oxide thin films. In addition, epitaxial ZnO film was also deposited onto a single crystalline Al2O3 substrate by this process. The relation between the obtained film and substrate epitaxy was examined, and photoluminescence of specimens was measured by triple wave of Nd:YAG laser. As a result, it was clarified that the epitaxial ZnO film prepared by this process is useful as laser material. 60 refs., 48 figs., 5 tabs.

    Microbes capable of a high biodiesel fuel (BDF) yield from moisture-containing oils assumedly waste oil are investigated. Lipase attributed to Rhizopus oryzae exhibits a high reaction rate of not lower than 90%. The process functions even when microbes are immobilized by BSPs. BDF does not affect driving performance, and black smoke is reduced. A process basic to industrial production is developed by use of a fixed bed reactor. In the production of ethanol from starch thanks to plural kinds of glucoamylase producing yeast, ethanol is produced at a rate of 7-8% under microaerophilic conditions in both proliferation and fermentation periods, which means a success achieved in growing arming yeast equipped with enhanced functions. A 20-liter class bench plant is installed and immobilization by BSPs is tested, when no problem is detected. In a reaction involving these immobilized microbes, a reaction rate near 16% is achieved. In the production of ethanol by yeast immobilized by BSPs, use of a fuzzy control system is studied, and it is found that prolonged stability is available when glucose concentration is sustained at 10-20g/liter.

    Presently, the aluminum demand in Japan is approximately 3.8 million tons, and the aluminum discharged as scrap reaches approximately 1.7 million tons/year. Out of the discharged scrap, 54% is recovered as the secondary metal, and the rest, 0.77 million tons, is not recovered and dumped for land reclamation. In future, if the present cascade type recycling goes on, it is predicted that a gap between supply and demand of about 0.5 million tons will arise. To cope with this problem, the following are the measures to be taken : 1) development of the technology to promote the use of recycled aluminum metal for automobiles in which a lot of aluminum is most likely to be used because of the increasing fuel consumption, etc. 2) establishment of a recycling system by which the waste sash discharged in quantity from the construction field is again used as sash. From the two points of view, which are needed in the case of using a lot of aluminum for automobiles, the heightening of competitiveness in the aluminum industry and the recycling in which the aluminum expanded materials used for automobiles are efficiently recycled as expanded materials in the recycling economic system, this survey extracted problems and made proposals, overlooking the state of the aluminum use in automobiles, state of the treatment of used cars, state of manufacturing/processing technology of aluminum products.

    This paper describes the achievements in the Sunshine Project in fiscal 1993 in the investigation for coal type selection. The investigation is purposed to elucidate the status of existence and resources of coals as the raw material for coal gasification and liquefaction, the coal quality features, and the gasification and liquefaction characteristics. The results will be used as the fundamental materials for technological development. Discussions will also be given on the coal applicability to the composite gasification power generation system in which liquefied residue generated in the process are mixed with the supplied coal. Coal quality analysis and a liquefaction test under the standard condition were completed on 389 test samples composed of 136 kinds of coals produced in Canada, Australia, the U.S.A., China and Indonesia. Coal types were enumerated according to the oil yield. A gasification test was performed on the specific gravity separated coals of Chinese coals to discuss the effect of change in the ash amount on the gasification characteristics. A partial coal combustion test revealed that fuel ratio, oxygen partial pressure, and oxygen molar fraction parameters affect the combustion characteristics. The micro-gravity field is effective in discussing the combustion characteristics of particulate groups of dust coal. A coal oxidizing test was performed, wherein oxidizing characteristics and spontaneous ignition performance were estimated successfully from temperature rise of heat stored in coal. The coal type matrix data were prepared. (NEDO)

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

    The purpose of the present surveys and studies is to discuss positioning of new energies for the case of forming the energy mix for Japan, and measures to arrange the conditions to have the positioning take roots in the society. One of the assignments in the discussion is to propose a system intended of improving the economic performance and of harmonizing with the existing energy systems, by establishing an adequate hybrid system composed of new energies and the existing energies. The current fiscal year will propose a hybrid system for manufacture or composite utilization of 'new synthesized fuels'. Another assignment is to discover a method to analyze quantitatively and evaluate how much the energy supply security in Japan will be improved, what the economic performance would be, and how the improvement effects will relate with cost of developing the new energies as a result introducing the new energies into the society. This fiscal year will analyze the importance of the evaluation factors themselves that make it possible to analyze such a dynamic change as oil crisis, and evaluate effects caused by fluctuation in crude oil price, effects on energy consumption and environment, and the energy mix.

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

    Surveys and studies were conducted for the development of technologies basic to the construction of an ultrahigh-speed huge-capacity high-frequency radio access and communication network, especially the network infrastructure, in the several 10 to several 100 GHz band. Some surveys covered the positioning of high-frequency high-output device modules as the key component, needs for their use in radio communication equipment, devices to be needed for their construction, technologies for their manufacture, process technologies for their embodiment, basic technologies for their materials, and so forth. Some others covered research on the marketability of high-frequency devices in the future, development of relevant technologies abroad, and so forth. The mainstream of high-frequency devices these days rests on the secondary electron gas system based on GaAs and InP, and therefore it is intrinsically difficult for them to yield high outputs. It is deemed to be important to develop technologies based on novel semiconductor materials, such as nitride semiconductors which have excellent properties as materials, toward the construction of a network infrastructure for the next generation.

    With an objective to develop a mass production technology to manufacture silicon raw materials for solar cells, and assist its practical application, surveys and analyses were performed on trends in development of the related technologies, the problems therein , market trends and industrial trends thereof. This paper summarizes the achievements in fiscal 1998. The worldwide production amount of solar cells in 1998 is estimated to have achieved 150 MW, and the silicon consumption reached the level of 2,300 tons. In spite of the economic recession environment, there was no change in the expansion trend. In developing an SOG-Si mass production and manufacturing technology, construction of pilot plants for each process has been completed, and entered into the operation research phase. In developing a technology to manufacture high quality poly-crystalline silicon substrates, fabrication has been completed on the on-line ingot cutting equipment and the plasma heating equipment, and the stage is now in operation research of continuous electromagnetic casting process. The conversion efficiency of the poly-crystalline silicon solar cells is 14 to 16% at the mass production level, whose enhancement requires indispensably the improvement in quality of the substrate. Discussions are required on the ingot manufacturing conditions in coordination with improvement in the cell manufacturing technology. (NEDO)

    Investigations and studies are conducted seeking for a CO2 fixation method improved by utilizing the photosynthesizing function of higher vegetation. Details of higher vegetation genes are being disclosed thanks to the rapid progress of studies making use of molecular biological techniques, and the application of the genetic mechanism to scientific and technological fields is becoming increasingly feasible. In particular, the role of the CO2 fixation enzyme RuBisCO has been elucidated almost completely. It has been learned that, in terms of photosynthesizing capability, the C{sub 4} plants (corn etc.) are 2-3 times higher than the C{sub 3} plants (rice, wheat, etc.), and 5-10 times higher than the CAM plants (cactuses etc.). Studies are also under way about the rice genome so that a photosynthesizing capability so high as that of the C{sub 4} plants may be endowed the rice plant. The metabolism and control of useful substances produced in the CO2 fixation process etc. in the higher vegetation are being investigated, and it is now expected that some day such useful substances will be produced and utilized efficiently. Researches are under way into the relationship between the green leaf that is the organ that performs photosynthesis and the organ (sink) that stores and utilizes starch and sugar is in progress, and now a new field is going to open where vegetables will be fully utilized.

    Since radiation of a laser diode (LD) is quite different from that of a light emitting diode (LED), evaluating their safety under one and the same standard (criterion) is questionable. The International Electrotechnical Commission (IEC), however, treats them in the same way. For the remedy of such contradiction and for the clarification of difference between the two devices in terms of radiation characteristics, they were quantitatively measured for spatial coherence and further measured for coherence dependency of their beam diameters. Well-supported threshold levels were prepared and biological tests were conducted for proposing a revision of the LED safety standard (IEC). As for the safety of equipment with built-in infrared devices, a measurement method was prepared as IEC61913 and devices are already at the CVD (chemical vapor deposition) stage. The result will be placed before the IEC/TC76 committee for deliberation of IEC60825-1 revision. Furthermore, to establish alignment between IEC and ISO (International Standardization Organization) in terms of laser-aided measurement which is the foundation for such committee deliberation, an ISO/IEC international joint group was created, and a technical recommendation was compiled and presented to the two standardizing organizations.

    The paper studied a system to effectively use unused and low-grade thermal energy (cold heat and hot heat) in the Tokyo-Yokohama seaside area. For transportation of thermal energy, the batch transportation, that is, off-line system was discussed which uses insulated tank loaded barges and railroad freight trains. Thermal energy supply sources are 1) 0.3 million kW class thermal power plant, and 2) LNG storage base of 3 million ton/year class. Thermal energy users are Tokyo (Haneda) Airport D.H.C. (District Heating/Cooling Co.), MM 21 D.H.C. and Shin-Kawasaki D.H.C. The cold heat energy supplied to these three is about 1.5 million Mcal/daytimes300 days/year, and the hot heat energy supplied is about 1.33 million Mcal/daytimes150 days/year. Cold heat is obtained from seawater after the LNG vaporization, and hot heat from heat extracted from thermal turbine. Subcooled ice was selected for cold heat medium, and PCM-120A for hot heat medium. For batch transportation, an STL heat storage system is used which transports plastic capsules sealed with heat medium. Oil saving of 62,000 tons/year and CO2 reduction of about 53,000 tons/year can be expected. 85 figs., 98 tabs.

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

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

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

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

    A study was made on effects of fluctuation of the exchange rate on business activities in the iron/steel industry. Fluctuation of the exchange rate is an uncertain element in working out a plan for future business activities, and hinders research development and equipment investment to be positively made. In the iron/steel industry in Japan, the rate of yen basis in trade settlement currency is especially lower than in other industries, and has a constitution which is easily influenced by yen appreciation. However, the iron/steel industry is an industry exporting products, and at the same time, is an industry depending on import for most of the main raw materials. Accordingly, the yen appreciation not only has negative effects, but has different effects, depending on the rate of shifting the amount of exchange rate fluctuation to local price, and on conditions of the rate of realizing price lowering which means that the exchange rate fluctuation reflects the lowering of imported raw material prices. If only these conditions are fulfilled, the yen appreciation even produces rather favorable effects in the iron/steel industry. In the circle, the conversion of the structure is being expedited for converting effects of yen appreciation to beneficial ones. Financially, exchange risk management is also necessary. 41 figs., 35 tabs.

    A thin film is developed which adds new functions to the surface of glass materials. The method is applied to the coloring of glass for the enhancement of recyclability (for example, by coating colorless glass bottles with colorful thin film) and to the functionalization of glass. Studies are conducted about the assessment of coloring-capable thin film basic characteristics, manufacture of liquids for application, and the manufacture of photosensitive gel thin film using chemically modified metal alkoxides. It is found that use of functional pigments reduces the transmissivity of ultraviolet and infrared rays. A method for manufacturing coloring liquids for application to glass bottles and a method of improving film durability using a 3,2-functional silane are established. Ultrafine gold/cuprous oxide powder, azobenzen based pigments, etc., are deposited on porous glass for the formation of a photoresponsive film. Conditions for color application to round glass bottles are optimized by use of an air spray device. Film exfoliation during colored glass bottle transportation is lessoned to a practically acceptable level by modifying the carton pack configuration. A large roll-type applicator is operated to successfully form a homogenous coating on a 1.8m times 1m glass plate. Double glazing capable of light modulation is also manufactured. (NEDO)

    An investigation was conducted into the systematical scheme for the introduction and promotion of environmentally friendly products mostly to the U.S., Europe and China. In the U.S., the introduction policy is given to one and all fields of the industry. The introduction policy of the U.S. has a characteristic that the introduction is left to the market principle by DSM or permit dealing, etc. except the preferential tax system and systematical finance in which the government is concerned. The policy of European countries is characterized by the idea preceding, standards or rules are first given, and the whole is pushed on to them. Accordingly, it seems that there is few atmosphere of expecting to receive the government side economic incentives from the corporate side. Legal regulations on the environment in China were prepared in a comparatively early time (1979), but the supervision of obeying the regulations and the appearance/spread of environmentally friendly product menus have just started. Accordingly, as the introduction policy on environmentally friendly products, there was found nothing valuable but the regulations. 12 refs., 3 figs., 15 tabs.

    Tests and researches were performed with an objective to elucidate a decaying mechanism of return wells when low-temperature hot water utilized for geothermal binary power generation is returned underground. This paper reports the achievements in fiscal 1982. For the simulated return testing equipment, the hot water supply line was changed, a supply line was newly installed for a water flowing test on hot water in the Hacchobara area, flow rate measuring lines for each system were newly installed, and the pressure detecting locations were changed. In the fundamental tests on the simulated return test, experimental researches were carried out on the following items: production of silica scale from geothermal water, solubility of silica acid, effect of pH on polymerization of silica acid, induction time in the polymerization process of silica acid, sizes of poly-silica acid particles in geothermal water, production of poly-silica acid due to temperature drop, oversaturation degree of mono-silica acid, and scale deposition. In the simulated return test, temperature of a simulated column reproducing the return ground bed, particle sizes, and hot water properties were used as the parameters for the test conducted. As a result, the decay in return wells was estimated to be governed predominantly by chemical deposition of the scales. (NEDO)

    Waste heat may be made good use of only after available waste heat is grasped. From this viewpoint, efforts were made to develop databases which would enable the preparation of an available waste heat map. Activities were conducted in the three fields of (1) the construction of an available waste heat database, (2) the construction of a database for estimating waste heat planar density distribution, and (3) the study of correlations between such databases and input-output tables. In Field (1), information on waste heat, gathered for each business type and facility type by questionnairing, was classified into 20 facility-oriented categories, and was used for the calculation of the amount of Japan's waste heat actually in existence with each business type and facility type. In Field (2), relations between the questionnairing-provided waste heat, purchased energy, number of employees, and the amount of shipment were analyzed for the estimation of the magnitude of factory waste heat using the number of employees. The amount of waste heat from each business type thus estimated was 310,000 T cal/year, which occupied 97% of the amount estimated by use of purchased energy. In Field (3), no satisfying correlation was detected between the amount of shipment and the amount of waste heat. (NEDO)

    Utilizing element technologies provided by Iwate University, Tohoku University, and Iwate Industrial Research Institute concerning the manufacture of dies, studies are conducted about designing techniques, ultrahigh-precision machining technology, anti-corrosion technology, molding releasing lubricants, dies, and the systematization of the process of manufacturing press-formed plastic compacts. In the development of technology of simulating coagulation in a molding die, a comparison is made between the result of a software-aided analysis and experimentally manufactured compacts in terms of tendency toward deformation, and a technique for reducing the amount of deformation is proposed. In the high-precision truing of grinding stones, the tip radius of the wheel can be 20{mu}m, and this suggests possible commercialization. In relation to direct cutting by an end mill, an experiment is conducted by means of CAD (computer-aided design)/CAM (computer-aided manufacture)-aided manufacture, and a comparison is made between 2.5-dimensional CAD/CAM and 3-dimensional CAD/CAM. It is then found that they are both effective. In the research and development of anti-corrosion technology for dies, it is made clear that the corrosion of real discharge-aided cutting-wire machine tools results from a trace of sulphate ions present in the working fluid.

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

    The melting point of ash is one of the most important physical properties in the process of coal gasification. A fluidized bed gasification furnace is suitable for the gasification of coal whose ash has a high melting point, but it does not work at temperatures higher than the melting point of the ash. A high-temperature gasification furnace, though not suitable for gasifying coal whose ash has a high melting point, gasifies the kinds of coal that the fluidized bed gasification furnace fails to deal with. Accordingly, almost all kinds of coal are to be appropriately gasified when these two types of gasification furnaces are available. The goal of the development effort is the achievement of a coal utilization factor of 99% or more and a thermal efficiency of 80% or more. The technology elements have to deal with the structure of furnace walls and refractory materials for them, discharge of slag, feeding of raw materials, recovery of exhaust heat, measurement and control, gasification furnace simulation, etc. A proposition is presented on a conceptual design and prototype for a 50t/d pilot plant in which the above-mentioned factors are organically integrated.

    The paper described the results of the FY 1999 research on continuous fiber reformed ceramics base composites (CFCC). As reinforced fiber, ZMI grade fiber was used. Polyzirconocarbosilane, raw material of that fiber, as matrices, was dispersed with zircon powder. The composite has remarkably more excellent heat resistance, oxidation resistance, corrosion resistance, and fracture resistance than metal, but so far there are seen no examples of the actual use. One of the causes is the shortage of the database for design of actual parts, especially, of the data on durability under actual environmental loads, and the reduction in reliability by a lack of life estimation technology. Accordingly, the basic experiments were carried out for the elucidation of environmental degradation and for the durability and development of life estimation technology. The experiments were made a step to the promotion of commercialization. As material form, minicomposite was used for unidirectional reinforcement for analytical convenience. Further, as a process to improve the durability of CFCC, minicomposite with glass seal put on was also evaluated. The experiments evaluated the residual strength after basic environmental exposure conditions, and the empirical formula for life estimation was proposed. (NEDO)

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

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

    The paper described the fiscal 1997 result. Using organic pigment and dye, the basic composition of sol-gel colored coating liquid for glass bottles and sheets was selected to clarify characteristics of gel films. Moreover, chemical modification and optical sensitivity of metallic alkoxide were studied to obtain a trially produced colored glass bottle use coating liquid. As to sheet glass, strength of the gel film is low, which requires further improvement. In relation to optical sensitive gel films, the reaction of various metallic alkoxides and {beta}-diketones was discussed to clarify chemical reactivity with utltaviolet rays. Trial design was also conducted of the coating equipment. The paper examined by literature the present status of recycling systems of colored glass bottles and the technical development in European countries. The problem is a method to wash colored bottles for sterilization. To make colored films durable, it is necessary to form films by organic-inorganic hybrid thin films. Also discussed was a possibility of changing the washing method by administrative guidance. 27 refs., 62 figs., 42 tabs.

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

As for the treatment of fly ash, an effort is made to recycle it into resources usable in the development of marketable products. For the detoxification of dioxins using chemicals, they are dechlorinated in a chemical reduction reaction. For their detoxification with help of microbes, it is found in an experiment of ash fly dioxin decomposition using Phanerochaete chrysosporium that the microbe reduces dioxins in both liquid phase and solid phase systems. The result of verification tests using chemicals shows that the reference level of 3ng-TEQ/g is easily cleared in the treatment of high concentration ash fly. In the detoxification of heavy metals, data is obtained indicating that the elution level of lead in ash fly is found reduced by 70-85% after treatment. (NEDO)

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

    As to ion exchange membranes for fuel cells, the R and D were made with the aim of clarifying the characteristics of the membrane required to realize highly durable modules and of demonstrating durability of membrane, and the FY 2000 results were reported. Concerning the low ion exchange capacity thin membrane, the following were confirmed: in perfluorosulfonic acid with ion exchange capacity of 0.84-1.0, the lower the ion exchange capacity is, the greater characteristics of mechanical strength are improved; the optimization of membrane thickness makes the design which satisfies cell characteristics and mechanical strength characteristics possible. In the durability test by medium-/long-term continued operation using each of small unit cell and large unit cell, the results of the stable operation of 5,000 hours using S1102 and S1201Q membranes were obtained. About effects of methanol, changes were observed in creep characteristics and piercing strength in the test on the environmental cycle at -40 degrees C to 80 degrees C. The membrane of low ion exchange capacity kept high elastic modulus even after the treatment at 120 degrees C, which indicated its usability for the higher temperature operation. (NEDO)

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

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

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

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

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

    A survey was made on autonomous responsive materials as a new material which reversibly change molecular structures and the aggregation state according to external stimuli. Autonomous responsive materials imitate environmental responsibility in the living organism system and have sensing, control and active functions for external stimuli. The materials are highly efficient and environmentally friendly. In biomimetic materials for soft actuators, drastic changes by temperature of elastic modulus of water-swollen hydrogel are used to the motion. In order to molecularly design stimulus-responsible polymer gel, studied are the relation between the micro structure and stimulus responsibility, dynamic correlation between the micro structure and the macro structure, etc. In the biomedical field, new cure and diagnosis using innovative materials are expected, and the application of autonomous responsive materials to the field is studied. For example, using hydrogel responding the temperature and the surface and controlling by temperature the interaction with components of the organism such as protein and cells, drug delivery in the organism is optimized. Also studied is the application of hydrophilic/hydrophobic changes by temperature to the chromatography. 215 refs., 47 figs., 11 tabs.

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

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

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

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

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

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

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

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

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

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

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

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

    With an objective to assist research and development to put thin film solar cells for power use into practical use and a research to put thin film solar cell manufacturing technologies into practical use, survey and research have been performed on trends in the technologies inside and outside the country. Characteristic points in thin film solar cells during the current fiscal year include: expansion of production scale of amorphous silicon solar cells, rapid progress in poly-crystalline silicon thin film solar cell technologies, and enhancement of performance in large-area modules in the a-Si, CIGS, and CdTe systems. In the trends in research and development of amorphous systems, expectation is heightening on elucidation of optical deterioration phenomena, and establishment of suppression technologies thereof. Although the highest efficiency was not renewed in thin film solar cells of small areas, progress was seen in the post-stabilization efficiency in large-area modules. A thin film solar cell manufacturing plant having an annual production capacity of 20 MW was put into operation in October in Japan. Micro (poly) crystalline silicon based solar cells have high possibility of being compatible in cost reduction and performance improvement, and energetic researches are being carried out on them in recent years as the most promising candidate of the next generation solar cells.

    Innovation plays an important role for Japan to flexibly utilize its achievements for the purpose of properly responding to new business environments and to secure competitiveness in the market. Japan lacks experts equipped with knowledge and ability as regards technology development and management which are necessary for the planning and creation of technologies, and is also short of institutes for raising experts. In America, technology management won an important position in the 1980s in the effort at industrial renovation, and the industry, government, and academia in a body endeavored to elevate the level steadily, continuously, and deliberately, to eventually provide a source of great propulsion and international competitiveness toward today's economic success. Investigations were conducted, and a proposition is made for the establishment of an international technology management research center. Such a center will study technology management and innovation through international exchange based mainly on the industrial circle and through the organic coordination of the industry, government, and academia for widely observing changes in international society for economic frontier cultivation. A practical training and intelligent network will be organized on the global scale, which will serve as an information transmitter. A skeleton of the plan is shown. (NEDO)

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

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

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

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

    After the shock of Hyogoken Nanbu Earthquake in 1995, protection against level 2 earthquake becomes important subject for civil structures. Subsequently plastic design methods for steel piers have been studied and rapidly introduced. The authors developed a method to evaluate the earthquake resisting performance of a steel pier with a single mass model. This model is useful for design because of its simplicity but on the other hand it can not consider the effects of piers` interaction in space. To include this effect in an analysis a simple 3 dimensional calculation model of box-column pier is developed. (author)

    Fracture behavior of Al2O3-TiO2 sprayed ceramic coating was investigated at low cutting speeds when using two dimensional cutting. Scanning electron microscope was used to observe the generation, development and propagation of cracks during cutting. Small cracks and fracture have been developed in the cutting groove along the cutting direction, and there has been many fractures in spray particles unit. In the initial stage of cutting, radiant cracks have developed on the sprayed coating, however, linear big cracks starting from the cutting edge towards the cutting direction, have developed. The cracks have developed along the grain boundary of coating component, and cracks progressed along the portion with weak bonding force. When the depth of the cut was under 5[mu]m, the cutting face has formed many microfractures, and the cutting has been very stable. It has been necessary to select the cutting conditions that do not cause big fracture, microcutting and so on, in order to achieve favorable surface condition with minor fractures. 8 refs., 13 figs., 2 tabs.

    Research and development is actively conducted on machining technologies using plasma in various fields, with studies energetically pursued on etching techniques or those of forming a thin film by the use of high frequency and microwave plasma. The EBEP system jointly developed by Kawasaki Heavy Industries Ltd. and Institute of Physical and Chemical Research is a plasma source for forming a high density plasma by implanting into a plasma chamber from the outside a high-current electron beam accelerated to an energy of approximately 60 to 100eV where the collision cross-section of gas ionization is maximized. The characteristics of the system are such as (1) it enables electron energy distribution to be controlled from outside by varying acceleration voltage, (2) it excels in the controllability of ion energy and (3) it allows to form a steady high-density plasma in a nonmagnetic field. This paper presents the generating principle of EBEP, its plasma characteristics, etching technique using EBEP, thin film forming technique by EBEP-CVD method, and multipurpose apparatus for research and development. 6 refs., 7 figs., 1 tab.

    A `laminated rubber tile` and a `shock absorbing holed-in anchor` were devised in connection with the apron of a dam for a hydroelectric power plant. As the result of a survey on the hydroelectric power plants, ten plus places were observed where a general kind of concrete was severely worn in the company territory; but, there were substantial number of rubber materials that had still been sound for over ten years after the installation. In spite of the soundness of the rubber tiles, however, it was observed that their anchor supports had been cut and separated. An abrasion comparison test of concrete and rubber materials revealed that the rubber materials were considerably superior in abrasion resistance. Various rubber tiles were tested for abrasion resistance, tear strength, tensile strength, impact strength, etc.; and methods for fixing rubber tiles were also tested such as a holed-in anchor, chemical anchor and adhesives. As a result, a laminated rubber tile was designed with its upper layer constituted of a rubber sold on the market and its lower layer of a fiber reinforced rubber also on the market, and so was a shock absorbing type holed-in anchor. 1 ref., 11 figs., 4 tabs.

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

    A cement-based filler is one of the back filling materials used in radioactive wastes disposal facilities. This paper describes fundamental tests performed on a filling material as to its filling performance, water permeation characteristics, and adsorption property to cerium by using the normal cement mortar (SM) that uses the water-to-cement ratio of 40% and the silica fume mortar (SFM). Furthermore, model wastes were fabricated by using a filling mortar of about 1 m{sup 3} and a 200-liter drum, which were used for tests on the filling and water cut-off performances. The result of the fundamental tests revealed the following matters: all of the materials show good filling performance and adsorbability when an adequate amount of high-performance water reducing agent is mixed; and the diffusion coefficient of the SFM is less than one tenth of that for the SM, showing high water cut-off effect. It was made clear from the tests using simulated test pieces that the Lugeon test value and water permeation coefficient of the SFM is less than half of that for the SM, and high water cut-off effect can be obtained by using the SFM. 11 refs., 8 figs., 4 tabs.

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

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

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

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

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

    In order to clarify the thermal decomposition behavior of nitrobenzene derivatives, the influences of interaction between nitro group and other substituents on thermal decomposition of nitrobenzene derivatives have been studied using sealed cell DSC and PM3 MO calculations. As a result, the mixtures of nitrobenzene and mono substituted benzenes having substituents containing hydrogen such as {sup -}CH{sub 3}, {sup -}COOH, {sup -}NH{sub 2}, and {sup -}OH showed 30-100 degree C lower T{sub DSC} value than nitrobenzene. Mono-substituted nitrobenzene having substituents containing hydrogen also showed lower T{sub DSC} value. On the other hand, PM3 MO calculations of hydrogen-bonded complexes of nitrobenzene and mono substituted benzene show that the hydrogen bonding of a nitro group and hydrogen of substituents may make the N-O bond length longer to induce the thermal decomposition. From These results, it can be said that the thermal decomposition of nitrobenzene derivatives would be unstabilized by the hydrogen bonding of a nitro group and a substituent containing hydrogen.

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

    Mechanical properties and failure behavior of weft knitted fabric reinforced composites were studied. Aramid fiber was used as reinforcement (knitting fiber), and epoxy resin as matrix. Different tensions were applied to the weft knitted fabric in a course or wale direction to prepare 5 kinds of fiber reinforced composites with different densities of the knitted fabric, and tensile test pieces were thus provided by cutting each composite in a course or wale direction. As a result, the weft knitted fabric reinforced composite offered a dynamical anisotropy, and the tensile strength of the test pieces was higher in wale direction than course one. Fracture in a course direction occurred at the section with extreme low fiber content, while fracture in a wale direction occurred at a loop interlocking region due to stress concentration. The tensile strength was constant or increased in a course or wale direction by stretching the knitted fabric before molding, respectively. 21 refs., 15 figs., 2 tabs.

    This study was performed to clarify the mechanism of mixture formation at peripheral area of diesel spray with PIV technique. Two dimensional cross-sectional photographs of diesel spray were taken with double pulse laser sheet. Local fuel spray particles were analyzed with an auto-correlation method and velocity vector and vorticity of the fuel spray particle were obtained. The vortex number increased and vorticity scale became smaller and its value grew higher with both smaller injection nozzle diameter and higher fuel injection velocity. With this injection condition, the mixing of fuel spray with ambient gas seems to be improved and the turbulence is expected to increase in the regions of higher vortex number, higher vorticity and smaller vorticity scale. Based on above results, the branch-like structure of diesel fuel spray was considered to be caused by vortices which formed in the shear layer between the spray and the ambient gas. 14 refs., 18 figs., 1 tab.

    This paper discusses the heat transfer analysis in a furnace for LPG reforming to produce gas enriched hydrogen. The three-dimensional combined radiative and convective heat transfer processes in a furnace for LPG reforming is simulated by introducing the radiosity concept into the radiative heat ray method for an accurate radiative heat transfer analysis. Together with an analysis of the chemical reaction in the reactor tubes of the furnace, the heat transfer simulation gives the three-dimensional profile of the combustion gas temperature in the furnace, the tube-surface heat-flux distribution and the composition of the reformed gas. From the results of the analysis, it was clarified that increasing the jet angle of the heating burner raises the gas temperature and the tube surface heat flux near the burner entrance, and that the flame shape is the most important factor for deciding the heat flux distribution of the tube surface because the heat transfer effect by flame radiation is much more than that by convection of the combustion gas. 18 refs., 9 figs., 2 tabs.

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

    Newly designed grout-filled coupling sleeve is discussed, which uses as the sleeve an electric resistance welded tube with protrusions formed in a checker pattern on its inner wall and is capable of using various premixed grouting materials available on the market. Specimens are subjected to uniaxial tensile loading and positive/negative cyclic loading, and the impact of various factors on the basic performance of the specimens and their stress/distortion characteristics at local spots in the reinforcing bar are disclosed. In the positive/negative cyclic loading in the plastic region, however, such findings are not obtained. In view of the stress/distortion characteristics at local spots in the reinforcing bar, a method is proposed for estimating the coupling strength and fracture type. A method for estimating the deformation behavior of the coupling, however, is not proposed. Investigations are conducted into the manufacture and installation of the grout holding framework, coupling fixing jigs, plugs, etc., and it is found that precasting should be studied in the future. 38 refs., 156 figs., 30 tabs.

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

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

    The purpose of this project is to develop and demonstrate the utility of feedback type gait training equipment designed for the measurement and evaluation by a walking training of the aged or patient. As similar concepts of walking training, a locomotion in the water for the aged is applied in rehabilitation. Our development of this study established the system of a suspending mechanism which revolves around the prop, and a walking on the circular type force plate by the aged or patient. It is possible to detect a walking reaction force of several patients from force plate simultaneously. And then, the data from force plate makes feedback signal to put up the patient like a buoyancy in the water. Concerning the evaluations of walking pattern a step range, a hanging ratio and a walking speed, etc. are acquired for each patient by the acknowledgment base. This system is actively able to perform a walking training continuously compared with conventional passive gait equipment. (NEDO)

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

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

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

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

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

    In order to clarify problems involved in application of Weibull probability distribution used for estimation of power production by a large wind turbine to a small wind turbine, and solutions thereof, the estimated results are compared with the observed ones. The conventional estimation method, when applied to a small wind turbine, tends to overestimate production of power, because of overestimated production in a high wind velocity range which occurs less frequently. Estimation of power produced by a wind turbine is based on working wind velocity range, determined from the furling mechanism for the power generation characteristics of the wind turbine concerned. In the case of a small wind turbine, on the other hand, better estimates are obtained from the working wind velocity range in which Weibull wind velocity distribution is used to determine probability of occurrence. For wind turbines working at low to medium wind velocities, such as Savonius wind turbine, the estimates are in fairly good agreement with the observed results, by which is meant that the conventional estimation method aided by Weibull distribution can be directly applicable to small wind turbines. 4 refs., 3 figs., 3 tabs.

    Study was made on application of a hydrogen engine to series hybrid electric vehicle (SHEV). Power of 20kW (for steady driving of a vehicle of 1t in total weight on flat road surface at 100km/h), and NOx emission concentration equivalent to that of EZEV (equivalent zero emission vehicle) were used as target performance. One of the merits of using a hydrogen engine for HEV is that conventional high-reliability gasoline engines can be used as hydrogen engines only by a bit of modification. A modified conventional 4-cylinder 4-cycle gasoline engine was used for this study. Hydrogen gas was continuously supplied through an intake manifold for premixed combustion by spark ignition. Brake thermal efficiency was improved from 30.5% to 35.5% by use of a high compression ratio and reduction of friction loss. NOx emission concentration could be controlled within 10ppm by ultra-lean combustion even at excess air ratios over 2.5. Both high efficiency and low emission were achieved at the same time around 3000rpm in engine revolution. 4 refs., 12 figs., 1 tab.

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

    Recently, a fault diagnostic expert system was prosperously developed as an objective of chemical plants and nuclear power plants. In this paper, a fault diagnostic method using modularized knowledge was proposed, a fault diagnostic system was constructed for an experimental plant, and the effectiveness of this method was clarified by carrying out a fault diagnostic experiment. The characteristics of the proposed fault diagnostic system were as follows: The necessary knowledge for diagnosing faults was made into each process element. Based on this method, the revision and addition of a knowledge base could be carried out in each element, and the design change of a plant could be flexibly corresponded by only changing the related part of the process flow graph. The estimated results were stored into the working memory, not only faults of an element in which faults resulted could be estimated, but also the fault propagating path could be clarified. 8 refs., 6 figs., 3 tabs.

    To cope with the global warming caused by CO2, an investigation was conducted into biological fixation. It is necessary to make a many-sided and comprehensive study on the mechanism of CO2 fixation, the scale (area and carbon holding density), the rate and the environmental impact of the introduction of the technology and the technical problems, and to make a quantitative evaluation of each of the methods in order to make them practical proposals. The global ecosystem is classified into the land biota and ocean biota, and each typical ecosystem was surveyed in terms of the surface area, the carbon holding amount (presently existing amount), the net primary production amount, the required nutrient salt amount, the transpiration rate, etc. Next, a discussion was made on the increasing effect of the carbon fixation amount by changing the present ecosystem from the aspect of scale and rate. At the same time, a study was carried out of energy efficiency, economical efficiency and problems. Last, elementary technology was taken up which seems to be important for implementing measures for the biological carbon fixation. As to the ocean, it is necessary to obtain information, which is not sufficient to utilize marine biota for CO2 fixation, especially on the mechanism of depth-direction transfer of organism and its quantitative grasp. As to the land, one of the measures is conversion of the ecosystem where the amount of carbon fixed is small to the ecosystem where the amount is large. 249 refs., 58 figs., 51 tabs.

    For solving the global warming problem and constructing the resource recycling society, a demand for highly recyclable light-weight Mg alloys is increasing for energy saving and recycling improvement, in particular, for automobiles and electrical appliances. However, use of Mg materials is limited because its poor workability. This research targets development of the material with a rich recyclability and a rich workability for forming complex shapes, and its working technology. Leading research was made on development of the continuous high-strain rate (more than 10{sup -2}/s) super- plasticity material forming process from raw materials to products of Mg alloys, and establishment of the production technology free from technological barriers. The research result showed that for the recognition of Mg alloy as low- environment load super light-weight industrial material, establishment of the composite resource-saving energy-saving production process including recycling and reusing is necessary at the same time as establishment of the high- strain rate super-plasticity material forming process.
