    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.

    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)

    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)

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

    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.

    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 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.

    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)

    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)

    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)

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

    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.

    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.

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

    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 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)

    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)

    The project aims to dry and pulverize into PDS (pulverized dry sludge) the waste (concrete sludge) discharged from ready-mixed concrete plants, and to develop its practical application. The fine sand component contained in the waste water after washing is removed to the maximum extent, and high-quality sludge-based PDS suitable for reuse is recovered. The process comprises an aggregate recovery stage, fine sand removing stage, coagulation/sedimentation stage, dewatering stage, crushing stage, drying stage, and a collection stage. High-quality PDS contains 30-40 mass% of CaO and 10-20 mass% of SiO{sub 2}, and its particles have an average diameter of 3-20{mu}m and an average specific surface area of 5,000-30,000cm{sup 2}/g. A particle is roundish with its angles rounded off. As for the fine sand component, not less than 90% thereof is removed by a wet cyclone method, and the water is collected and supplied for PDS manufacture. The development is already complete of powder and liquid coagulants, of which not less than 96% is inorganic, as coagulants exclusively for use for concrete. The quality of the manufactured PDS fulfills the target values, and it is concluded that PDS is recyclable like blast furnace slag or fly ash. (NEDO)

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

    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.

    Summarized herein are the reports on the R and D of coal-fired magneto-hydro-dynamics (MHD) electrical power generation, received by March 30, 1990. For the coal combustor, the air flow tests have been conducted using a 5MW-scale plastic model since 1984, and the model has been later scaled-up to 15MW. The actual combustion tests have been conducted using a 1MW-scale combustor, designed based on the results of air flow tests using the 15MW-scale model, mainly for the cyclone combustor in the first stage. For a coal-fired generation channel, the studies on the cathodes and insulation walls have been conducted since 1986, the research themes including causes for and measures against inter-cathode shorting, and insulating walls of SiC. The anode walls have been studied since 1986, deepening understanding of, e.g., the anode arc phenomenon and anode discharge phenomenon which relates to the causes for exhaustion of the inter-anode insulators and anode materials. For the high temperature regenerative heat exchanger, the existing materials have been screened since 1985, and the basic data related to, e.g., slag viscosity and its effects on material corrosion have been collected since 1986.

    Nitrogen monoxide is a strong greenhouse effect gas having warming up index per molecule 300 times greater than that of CO2, and is designated as the object of reduction in the Kyoto Conference. The present preceding research discusses necessity of performing research and development works related to reducing the emission of nitrogen monoxide, and if it is necessary, places the final objective on proposition of what researches should be planned. Fiscal 1997 being the first fiscal year of the preceding research has surveyed emission amount from different emission sources, and enumerated the research and development assignments. Fiscal 1998 falling under the final fiscal year summarizes the emission amount including the future trends, surveys the feasibility of the promising technological measures through experiments, and proposed finally a research and development plan desired of implementation in the future. The proposal contains a research plan placing development of nitrogen monoxide decomposing catalysts and automobile catalysts as the main objectives. Among the domestic nitrogen monoxide generating sources, about 2/3 is the man-made generation sources, hence catalysts, if developed, may be applied to such facilities as combustion furnaces. (NEDO)

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

    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.

    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.

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.

    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)

    This paper explains the results during fiscal 1998 of ion exchange membranes in the development of polymer electrolyte fuel cells. Studies were made on three kinds of standard and two kinds of experimental membranes selected among the Flemion membranes, which are perfluorosulfonic acid membranes made by Asahi Glass Co.,Ltd., and also on the Nafion membranes by Dupon as reference. As the resistance evaluation of the environmental cycle for the membranes, a temperature cycle test was carried out, with the characteristics measured such as moisture content, membrane resistance, mechanical properties, and gas permeability, so that the effects were examined of the temperature cycle on the membranes. Evaluation was also commenced on the water permeability, an important substance-moving characteristic of ion exchange membranes. In the evaluation of the characteristics of membrane-electrode assemblies, the environmental cycle test was performed by joining electrodes to membranes, with the evaluation similarly made as for the membranes alone. On the basis of a correlation between the water permeability and the cell performance, studies were made on the effect of thickness of the membranes on the cell performances. A continuous stability/durability operation of 3,500 hours was verified using Flemion R. As for membrane reinforcement, studies were continued on the cloth and fibril reinforcements as in the previous year.(NEDO)

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

    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.

    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.

    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 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.

    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.

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)

    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)

    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)

    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.

    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)

    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.

    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 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)

    Efforts are made to develop a system to collectively detoxify dioxins and heavy metals in incinerator fly ash or in polluted soil using microbes and/or chemicals. In the use of chemicals, verification tests are conducted for a system to detoxify dioxins and toxic heavy metals simultaneously. In the use of microbes, an effort is made to develop a low cost energy conservation type treatment system based on what is provided by the study of microbes such as Phanerochaete chrysosporium. 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)

    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.

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.

    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.

    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 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.

    The paper proposed a high-performance error correction method for restoring the lack and errors of digital data to the original state. In FY 1998, the algorithm of coding/decoding was mounted on personal computers. The program was verified in which the code length and dimensional number as parameters were made changed, and the program structure with variable parameters was acquired. Moreover, forms of connection /communication protocol with external equipment were designed which are needed in case of making it semiconductive. In FY 1999, the best decoding method in the algorithm study was selected, and the error correcting ability was improved. In making the algorithm semiconductive, using the design in which the parallel processing was paid attention to in the development of mounting using EPGA, circuits of high speed coding/decoding were established. The development of semiconductors for coding/decoding which work at 10 MHz was made possible.

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

    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.

    For development of production technologies suitable for environment, safety and advanced information-oriented society by improving the flexibility of production lines, some new measurement technologies were researched. Problem solution was attempted by combining the in-situ multi-dimensional measurement technology capable of easily obtaining various 3-D information with the non-contact photon measurement technology superior in operability and sensitivity under any environment conditions. This solution requires a compact radiation source with higher brightness and wider spectral range, and a high-sensitive detector. The technology concentrating photon onto minute regions, high-efficiency transmission, and control technology of photon wave front are also necessary. Development and international standardization of a common interface is unavoidable. In addition, its network is essential for advanced use of multimedia,. In the future, the comfortable life surrounded by advanced products and multimedia, comfortable social environment, safety and resource saving will be achieved by this technology. 94 refs., 75 figs., 15 tabs.

    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)

    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)

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)

    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.

    Based on the concept of human life engineering database, a study was made to know how to technically make such a database fittable to the old people in the age-advancing society. It was then proposed that the old people`s human life engineering database should be prepared to serve for the development and design of life technology to be applied into the age-advancing society. An executive method of structuring the database was established through the `bathing` and `going out` selected as an action to be casestudied in the daily life of old people. As a result of the study, the proposal was made that the old people`s human body function database should be prepared as a R and D base for the life technology in the aged society. Based on the above proposal, a master plan was mapped out to structure this database with the concrete method studied for putting it into action. At the first investigation stage of the above study, documentation was made through utilizing the existing documentary database. Enterprises were also interviewed for the investigation. Pertaining to the function of old people, about 500 documents were extracted with many vague points not clarified yet.

    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)

The paper described the system of the conversion and use of biomass into energy, conducted the positioning of the liquefaction, and outlined a history of the liquefaction chemistry and the study. To obtain basic data of characteristics of the liquefaction of various biomass raw materials, the liquefaction was conducted changing operational factors for the purpose of clarifying the product distribution of oil and by-products and oil properties. A comprehensive consideration was made of the liquefaction based on basic data and literature reports on the liquefaction of various biomass. From the above-mentioned studies, it was concluded that the energy can be recovered in a form of oil by applying the liquefaction to various biomass materials. A series of the study clarified effects of various operational factors on characteristics of the liquefaction as well as effects of classification of biomass materials and composition of the materials on characteristics of the liquefaction. 141 refs., 78 figs., 56 tabs.

    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.

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.

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

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

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

    As a plan to develop technologies to manufacture materials and substrates for thin film solar cells, it is intended to reduce defect density, enhance film forming speed, largely improve the photo-electric conversion efficiency and increase manufacturing productivity. These goals will be realized by establishing methods to control defect density, crystal particle diameters and crystallization rate in silicon crystal systems. A technology to form micro-crystal silicon-based thin films will be developed, that have superior photo-stability, and are capable of realizing low cost and mass production. Discussions will be given on a high-density plasma control technology, a fundamental property evaluation technology for micro crystal silicon thin films, and a device design simulation technology. A technology will be developed to form amorphous silicon layer on a stainless steel substrate by using the plasma CVD process. At the same time, discussions will be given on optical annealing and thermal annealing as reformation methods.

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

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

Concerning a gas table calculation program in coal combustion, it was prepared assuming 100% slag removal ratio in the combustor as the primary approximation. A combustor for MHD generation needs to efficiently burn fuel using high temperature pre-heated air as the oxidant, to fully dissociate/electrolytically dissociate seed, and to supply to the generation channel a high speed combustion gas plasma having a high electrical conductivity which is required for MHD generation. This year, an examination was conducted on technological problems in burning coal in an MHD combustor. As for the NOx elimination system in an MHD generation plant, an examination was made if the method studied so far in MHD generation using heavy oil as the fuel is applicable to coal.

Concerning the technologies already in existence in this field of research, a survey is conducted of the status of research and development of information interface techniques primarily at Stanford University, and a report is made thereon. Also reported is the information obtained at Technology and Persons with Disabilities Conference 1999. The result of a survey of the trend of research and development of the smart house under the TIDE (Technology Initiative for Disabled and Elderly People) project and the result of a survey of an information standardization project for equipment control in Europe are reported, and the result of a survey of the approach of Kyoto's welfare apparatus distributors to the development of equipment is made known.

    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)

    To effectively utilize unused sea weeds having ingestion obstructing activities for feed, the treatment by oxygen added enzyme has been investigated. Undaria pinnatifida was pasted and solidified with agar, to prepare the standard feed. Individuals of Holiotis discus hannai Ino were bred in the cistern. Extracts from ten kinds of sea weed distributed in the Sanriku Coast were added to the feed, which were compared with the standard feed to determine the ingestion obstructing activities. A testing method using cellulose painted aluminum sheet was also employed. All of the extracts from sea weeds having the ingestion obstructing activities exhibited the strong phenol reactions. The sensitivity of individuals of Holiotis discus hannai Ino depended greatly on the derived species and the chemical structures of phenolic substances. The {alpha}-hydroxymuconic acid semialdehyde (HMS), an enzyme decomposition product of catechol, provided no ingestion obstructing activity, and showed a little ingestion accelerating activity. This was considered to become ingestible through the biodegradation of phenolic substances. The HMS, a decomposition product of catechol 2,3-oxygen added enzyme derived from the petroleum decomposition bacteria, was prospective as a highly functional compound synthesizing material. 10 refs., 34 figs., 10 tabs.

    The paper studied the engineering for activating areas using natural energy. A system has started in which electric power companies purchase surplus electric power from the natural energy use power generation such as the wind power and photovoltaic power generation, etc., and a lot of local self-governing bodies in the country plan `projects to promote town` using the system. However, few engineers and makers can plan `a project to promote town,` making effective use of natural energy which is fickle. Therefore, first, the paper arranged the actual status mostly of the cases of `the projects` using natural energy which have been carried out in the country. Next, the trend of the natural energy utilization technology in countries including the U.S. was described. Moreover, assuming model areas in Japan for working out a concept of model projects on the natural energy utilization and town promotion, a concept was proposed making full use of the utilization technology which has now usability. Arrangement is being made for conditions for the full scale spread as seen in the subsidy system for general users. 3 refs., 176 figs., 61 tabs.

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

    The flow field around a Darrieus wind turbine is studied by flow visualization and PIV measurement in a rotating frame of reference to understand the unsteady nature of dynamic stall appearing at low tip-speed ratios. The qualitative nature of the dynamic stall observed by the flow visualization using dye injection technique is quantitatively reproduced in the instantaneous velocity distributions around the blade measured by PIV technique. These results indicate that two pairs of stall vortices are generated in one cycle of the turbine rotation and they grow in size as the tip-speed ratio decreases. The mechanism of the dynamic stall is found to be due to the flow separation over the suction side of the blade followed by the generation of in-flow motion from the pressure side to the suction side of the blade through the trailing edge.

    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)

    This research is conducted to search study themes of chemistry expected towards the 21st century. The complex compound in the fundamental chemistry field and the bio-medical materials in the applied chemistry field are taken up. Bio-medical materials are used for the restoration, rehabilitation, and treatment of the organ and the improvement of its functions. For implants such as hearts, anti-thrombin and anti-calcium precipitation effects and high endurance are required. In this field, special copolymers and bio-membrane-emulating surfaces are studied. For artificial organs, hybrid type materials combining cells, and physiologically active and artificial materials are also studied. There are studies on the missile therapy of drugs and DDS (drug delivery system). The complex compounds contain metallic elements, such as Fe, Mn, Co and Cu, and groups known as ligands which combine these metal elements. They can have a variety of stereo-structures and physical properties. They also exhibit a diversity of functions including electron donor bonding, molecular recognition, chemical substitution, and pharmaceutical activity. These features open up a promising potential for their prospective use as physiologically active substances, cancerostats, new materials, artificial photosynthesis, memory elements, and complex catalysts. 88 refs., 35 figs., 6 tabs.

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

    Importance was studied of making a research on the chemical process technology using the supercritical fluid. As for its effect on global warming, the amount of CO2 emission was compared during the operation between the conventional process and the process using the supercritical fluid, the CO2 reduction rate and amount were trially calculated, and a CO2 reduction of a several ten thousand ton scale in carbon conversion was predicted. As to hazardous materials and the reaction of waste retrieval, it was made clear that the process using the supercritical fluid was valid also for objects for which the chemical process used to be impossible, which indicates a possibility of the widening field of application. Concerning its effect on the energy conservation, energy reduction of several ten thousand tons in heavy oil conversion was predicted by replacing all the existing processes with supercritical fluids. Relating to the recycling, with the use of supercritical fluids, the process is possible which produces higher quality and yield and fewer unnecessary products such as char than the conventional process. 197 refs., 102 figs., 71 tabs.

    Creation of new biocatalysts was surveyed to convert chemical reactions into environment-friendly processes. Biocatalysts are characterized by their high catalytic activity, uniqueness of reactions, and non-pollution under mild conditions. Stability is required for them, such as heat resistance, solvent resistance, acid resistance and alkali resistance, under severe conditions. For the development of new biocatalysts, it is necessary to multiply utilize the techniques containing enzymes, ribozymes, mold synthetic polymers, chemical modification, and non-natural proteins. Natural enzymes have been conventionally improved through the search, imitation and modification. Hereafter, new biocatalysts with functions required for the reactions should be created by integrating information regarding functions, structures and activation of these enzymes. It is indispensable to cooperate closely with supporting techniques, such as gene engineering, organic synthesis, biophysics and computer chemistry. 35 refs., 26 figs., 1 tab.

The goal is the software of very high adaptability by using soft-software components and flexible assembly. The CASE tool platform Sapid based on a fine-grained repository was developed and enforced for raising the abstraction level of program code and for mining potential flexible components. To reconstruct the software adaptable to a required environment, the SQM (Software Quark Model) was used in managing interconnectivity and other semantic relationships of among components. On these two basic systems, we developed various methods and tools such as those for static and dynamic analysis of very flexible software structures, program transformation description, program pattern extraction and composition component optimization by partial evaluation, component extraction by function slicing, code encapsulation, and component navigation and application.

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

    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)

    Discussions were given on features of various kinds of coal liquefaction catalysts exhibited by them in hydrocracking of coal (Taiheiyo coal), and particularly on selectivity of the reaction in its initial stage. Four kinds of catalysts were tested: Adkins catalyst which is an oxide of copper and chromium, Fe2O3+S, Mo-TiO2 and MoS3-Al2O3. Three grams of coal and 0.3 gram each of the catalysts were charged into an autoclave reactor and experiment was conducted under an initial hydrogen pressure of 10 MPa, temperatures from 653 K to 693 K and for durations of 0 to 120 minutes to derive apparent reaction rate constants. The MoS3-Al2O3 catalyst has promoting the reaction apparently in the primary reaction at any temperature, while the other catalysts had the rate constants varied in the initial and the later stages. It was recognized that the temperature dependence of rate constants varies considerably according to the types of catalyst. Particularly the MoO3-TiO3 catalyst has small temperature dependence in the rate constants, and high molecular weight reducing power. 3 refs., 4 figs., 3 tabs.

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

    Among the research cooperation in the development of laser radar for environmental measurements with Indonesia between FY 1993 and FY 1996, results of the research and development of the environmental network are summarized. For the environmental information network, the Tokyo NOC is linked as an Internet connection point in Japan with the Jakarta NOC using an international dedicated line with a capacity of 64 Kbps. The Tokyo NOC is linked with domestic environmental information researchers using Internet. Thus, data stored in the data processing system of laser radar can be exchanged, information in both countries can be exchanged using E-mail, and data can be accumulated. For the research cooperation with Indonesia, research of path control and information relay server, research of effective transmission of data on the network, and research of multimedia communication have been conducted. The multimedia communication, distributed processing, and extension of dedicated line network using PPTP have been also conducted. 39 figs., 4 tabs.

    We have developed a high performance hydrogen storage alloy (MH alloy) suited to NiMH batteries for EV use. During the course of the development, the effects of alloy composition and structure (B/A ratio in AB{sub 5}) on cycle life and high-rate discharge of MH electrodes were investigated using mainly SEM, XRD, TEM analysis. It was found that Co content and B/A ratio (5.1/5) of MH alloy have significant effects on corrosion resistance and high-rate discharge at low temperature. Further, the surface treatments of MH alloy with weak acids and hydrophobic agents were effective for improving the initial activation and for depressing the cell internal pressure build-up.

However, there are many problems in digitalization, and it is feared that the plan will be delayed. As to telecommunication quality and connection quality, the telecommunication completion rate, SCR, is very low, approximately 24% on average, which is equal to that around 1990 in Japan. The business service for users is all bureaucratic since they have a lot of applications for the installation piling up with no exception to the rule of developing countries. 23 figs., 10 tabs.

    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 elastic response of VLFS of 1200m long in wave was studied experimentally using a water tank and integral elastic model of 1/80 scale. As offshore airport, a ultra- thin box type floating structure of 5km long, 1km wide and several meter thick is used, and the effect of elasticity is not negligible for such a structure. The experiment used a water tank of 160m long, 30m wide and 3.1m deep. Supposing a water depth of 20m for real VLFSs, the experiment was carried out mainly in a local shallow water area prepared with a temporary bottom together with that in a deep water area. A simple mooring equipment with a linear spring equivalent to real VLFSs was used. The integral floating model was prepared by not mechanical but welded junction to obtain uniform elasticity. The response in wave showed a complicated 3-D behavior, offering useful data for verification of a behavior estimation method. The response was nearly equal between shallow and deep water areas at the same wave length, and the response amplitude in regular waves was equivalent to the significant amplitude in long and short crested irregular waves. 7 refs., 8 figs., 3 tabs.

    With types of general cargo vessel and VLCC vessel as the object of discussion, a method was discussed to estimate fluid force acting theoretically on a hull during maneuvering movement, taking frame line shape into consideration. A vortex model was improved by giving consideration of time-based decay on intensity of discrete vortex lines based on the Rankine vortex. Modeling of flow fields around a hull was attempted to deal with movements in which width and draft are small as compared with the ship length, and turning angle speed and deviation angle are small. It was assumed that the ship speed is slow and effects of waves can be disregarded. Specular images of the hull were taken with regard to free surface, and handled as a double body model. Speed potential to express flow fields around a hull is required to satisfy the following five boundary conditions of Laplace, substance surface, free vortex layers, infinity and exfoliation. The potential may be handled as a two-dimensional problem in a field near the hull by using assumption of a slender and long body and conformal mapping. It was found possible to estimate hull fluid force with relatively good accuracy. Fine linear coefficients derived from the estimation were used to have performed highly accurate determination on course stabilization. 5 refs., 6 figs., 2 tabs.

Further, in the deep-sea bottom storage method, a simulation to calculate the range of PH effects was conducted presuming the specified amount of CO2 and applying known physical values, and evaluation of the CO2 ocean discharge/solution method was made. A method was also studied for experiments on water bacteria and benthos. 127 refs., 102 figs., 81 tabs.

    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)

    The effect of silica fume and ground blast furnace slag in concrete on the content of superplasticizer, and dynamic properties of hardened mortar with such admixtures were studied experimentally. Although the dependence of a flow value on the superplasticizer was dominated by kinds of superplasticizers, blast furnace slag enhanced the flow value resulting in a high fluidity. Adsorption of superplasticizers onto admixtures was dependent on kinds of superplasticizers, and adsorption onto blast furnace slag was 1.3-2 times that onto normal Portland cement (NPC). The compressive strength of mortar increased by mixing admixtures, while the bending strength was enhanced only by mixing silica fume. Mixing mortar was lower in dynamic elastic modulus than NPC mortar at the same compressive strength, and the velocity of supersonic wave in mortar was scarcely affected by mixing. 11 refs., 14 figs., 3 tabs.

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

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

    The shape of osteoblast, gene appearance, gene of rice blast, cellular fusion of plants, gravity acceptance mechanism of unicellular organisms, and physiological and immunity functions of mice were investigated under the microgravity condition. The influence of gravity on the vital reaction and the influence of microgravity on the crystallization of vital substances were also investigated. For the observation of osteoblast, the fluorescence dye reacted with Ca was well taken in the cells. The microgravity affected the stability of rice blast, but hardly affected the protoplast culture of mushroom. The reaction of ciliate against the gravity related to the specific gravity difference between cells and outer liquid. The level of adrenaline in blood of mice increased during the drop. The moving speed of trigger waves of chemical parallel slit formed at the BZ reaction under the microgravity became 60% to 80% of that on the ground. In the case of crystallization at the deposition agent concentration of 1% to 4%, the turbidity showing the degree of crystallization changed complicatedly.

    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.

    This report deals with heat transfer in the melting process of crushed ice filling in a ice/water heat storage container. Volumetric heat transfer rate and melting end-time are measured when rectangular-type, small-stone-type and particle-type ice in the container are melted by circulation hot water. Melting end-time of small-stone-type ice is the shortest and that of particle-type ice is the latest. Volumetric heat transfer rate of small-stone-type ice and rectangular-type ice is larger than that of particle-type ice. The flow rate of circulation hot water throwing in container through a inlet pipe influences remarkably on heat transfer rate. 4 refs., 10 figs.

    In order to clarify the relationship between the heat transfer rate and the expansion bed in a group of horizontal pipes in a freeboard region (an area of the heat-transfer pipe exposed above the height of static particle bed from the beginning) in a cold model of the fluidized bed, particle behavior was measured using an optical measuring method. The light axis position was set higher than the heat-transfer as X {sub p} in a direction perpendicular from the distributor, and the static bed height was set to L {sub c}. The frequency of particles and particle lumps coming to presence between the light axes is termed V {prime}{sub p}(time-averaged dimensionless amount of the optical probe output). The V {prime}{sub p} decreases with an increase in the flow velocity, and, when the difference between the probe tip and the static bed height, X {sub p}{minus} L {sub c} is small, it shows the minimum value at a certain flow velocity and then rises again. The root mean square value of the probe output, V {prime}{sub f} increased with an increase in the flow velocity, reached its maximum, then decreased to the minimum, and rose again. The flow velocity that takes the maximum heat transfer rate can be identified from the relationship among the dimensionless amount of the maximum expansion bed height and the average expansion bed height, the dimensionless height of X {sub p} when V {prime}{sub p} and V {prime}{sub f} obtained at each X {sub p} show the extreme values, and the dimensionless height of the heat-transfer pipes when the average transfer rate takes the maximum value. 6 refs., 5 figs.

Projects were then proposed. In the project for collecting/analyzing the trace quantity of blood, the anomaly is inspected at a molecular level from the collected trace quantity of blood to make the biochemical inspection painless for the patients suffering from infectious symptom or disease of adults. In the project for the high-accuracy and high-function measurement without invading the diseased part of living body, the configuration and metabolic function are measured by nuclear magnetic resonance to early detect the symptom of Alzheimer and other different obstinate diseases. In the operation support system project with three-dimensional images of living body, the three-dimensional information is obtained, by X-ray CT or MRI, about the diseased part of living tissue.

    In order to perform efficient and safe controlled blasting, attaining sufficient detonation from explosive is important. Therefore, a mechanism of detonation in a bore hole was studied. Two detonation phenomenon measuring methods were established: one is a continuous detonation speed measuring method by using a resistance wire probe, and another is a detonation mark observing and evaluating method using aluminum and metallic lead plates. Assuming delay blastings in multiple bore holes used practically, discussions were given on detonation phenomena of explosives under pressurized condition. Under dynamic pressure condition, size of the pressurization and delay time of the detonations affected largely the detonation. Discussions were given on blasting effect and safety according to difference in forward initiation and reverse initiation. The reverse initiation method was verified to have excellent blasting effect, maintain good face conditions, and assure safety against inflammable gases. A precision initiation method was developed, which can control the initiation time of a detonator more precisely. The initiation accuracy is more than 1000 times greater than the ordinary instantaneously detonating electric detonator. The precision control of the initiation time proved to develop greater crack propagation. Vibration and stone scattering were also controlled. This paper also describes application of the method to a rock elastic wave exploration technique. 136 refs., 99 figs., 13 tabs.

    To further enhance resource/energy conservation and environmental impact reduction, it is necessary to develop innovative chemical reaction process technologies. It is for this reason that 'development of next-generation chemical reaction process technologies' is being carried out under the New Sunshine Program. The survey and research, for the fulfilment of the above goal, aim to select important technologies and put in a easy-to-study order the problems contained in associated technologies for picking out tasks for future studies for the purpose of suggesting some subjects to be taken up for future development. In addition, studies are made about how a comprehensive technology assessment system should be. In this fiscal year, propositions are compiled for research and development projects on five subjects. Studies of subjects other than these five will also continue to eventually build concrete propositions on them. The said five subjects involve 1) the development and application of nonaqueous biotechnologies, 2) biotechnology-aided polymeric material creation processes, 3) construction of high-efficiency energy conservation processes using innovative grain handling technologies in the high-temperature reaction field, 4) manufacture of high-performance polymeric materials for batteries and development of battery fabrication processes, and 5) the development of an energy conservation process maximally utilizing environmentally-friendly polyolefin.

    For further resource and energy conservation and environmental load reduction, development is necessary on innovative chemical reaction technologies. This paper describes surveys on next generation chemical processes. As non-halogen processes subject to development of new catalysts, new processes were investigated and searching experiments and discussions were given on isocyanate, propylene oxide, and phenol. Technological progress in the C1 chemistry was investigated. Problems in hydrocarbon compound oxidation, hydroxylation, and decomposition by utilizing microorganisms were put into order as application of environmentally friendly technologies. Marine biotechnical possibilities were surveyed. The surveys were given on new processes utilizing the phase transfer catalyst forming a third phase, manufacture of biodegradable plastics, and a novel reaction system combined with self-separation process using molecular assembly. Possibilities were searched on designing a truly simple production system of highly energy saving type. Such fundamental common technologies as structure analysis, property control and reaction engineering were investigated for methods to manufacture functional micro-powder chemical materials. Development was discussed on a system for technology assessment over whole product life cycle to structure a technology assessment basis. (NEDO)

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

    The purpose of this study is to acquire fundamental knowledge about the factors for production and the physical properties of boards when wood powder is used as the main material and powder adhesive is used as the binder in the formation of wood boards under heat and pressure. The effects of temperature for pressing, specific gravity of board, and the ratio of adhesive on bending strength, internal binding force, and size and stability against moisture are investigated. The temperature behavior at the central area of boards under heat and pressure shows similar tendency of stagnation near 140degC which increases thereafter irrespective of the temperature of the hot plate in this experiment. The bending property increases linearly when the resin content is low, and shows the tendency of leveling off gradually when the resin content is larger than 20%. Linear relation with specific gravity if obtained in the 0.6 to 1.0 specific gravity range. Wood powder boards have high internal size stability in the thickness direction than ordinary wood boards. 13 refs., 11 figs.

    Temperature and humidity characteristics and condensation within walls under heating and humidification were studied experimentally in winter using two test houses of conventional and ventilated structures. The absolute humidity in conventional one fluctuated depending on temperature gradient, water flux due to humidification and water adsorption onto glass wool, and accumulated water increased with humidification. That in ventilated one was also affected by dehumidification through ventilation layers. Under heating and humidification, the absolute humidity increased depending on temperature rise and water flux within walls. In conventional one, condensation was frequently observed on felt in walls and others because of accumulated humidity, while in ventilated one, humidity was kept lower within walls even under heating, because humidity in walls was discharged through ventilation layers. Condensation was also scarcely observed on waterproof moisture-permeable sheets in walls and others. 3 refs ., 39 figs 1., tab.

    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)

The project is scheduled to be carried out in a 4-year plan starting fiscal 1993. In fiscal 1993, conducted were negotiations with Indonesia on its implementation and a field survey. Between January 6 and 15, 1994, the first field survey was made in terms of topography, climate, road network and traffic situation of Jakarta city, and the proposed sites for installation were reported. The paper also introduced the reception system on the Indonesian side and a request for technical learning through stay in Japan. The second field survey was conducted between February 27 and March 6, 1994. Indonesia requested that they want to make laser radar observation not only for the local area, but the one that covers industrial areas, central urban areas and residential areas. Incidentally, there was an opinion that it is important to elucidate the pollution mechanism. 19 refs., 43 figs., 6 tabs.

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

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

    The cause of unburned hydrocarbon emission in small DI diesel engines at light load was studied. An optically accessible engine which was enabled to visualize the squish area was used to investigate the behavior of spray, mixture distribution and so on. Based on these observations and engine tests, the factors such as the direct impingement of liquid phase fuel spray to the combustion chamber wall the unevenness of fuel spray among holes and spreading of the fuel droplets, mixture and flame to the squish area were supposed to be the cause of forming HC emission. 18 refs., 10 figs., 2 tabs.

    To clarify soot formation and oxidation process in diesel combustion, the natural emission of OH radical and the flame temperature were obtained in the combustion chamber of D.I. diesel engine. Further, soot were detected by LII (Laser Induced Incandescence) and LIS (Laser Induced Scattering) technique to assess the relative soot diameter and its number density. OH emission and flame temperature were compared with data of soot diameter and number- density. The results show that : (1) OH emission has relation to flame temperature. (2) OH emission arises latter than soot emission, because early soot at early combustion consume OH to oxidate. (3) As soon as it is ignited, soot particles are formed in the region of low temperature. 6 refs., 7 figs., 2 tabs.

    It was intended to reduce the thermal loads of solar-pumped solid state lasers (highly densified solar light is irradiated directly onto a laser medium to cause excitation. No electric power is required for the excitation.). For this purpose, experiments were performed by using a selective permeation film. Solar light includes wavelengths not effective for excitation, which causes heat generation and thermal loads such as lens heating effect and thermal stress compounded refraction, degrading the laser beam quality. The Nd:YAG was used as a laser medium, and a multi-layered film (composed of SiO2 and TiO2) which cuts wavelength below 500 nm as a selective permeation film to cut light having wavelengths not required for excitation. A laser transmitting experiment revealed that the slope efficiency is improved by 27% as compared to not using the film. Beam fluctuation was improved to 45%. Using the selective permeation film has realized more efficient conversion of the solar light into a beam with better quality. The results for calculation of heat lens effect by using temperature distribution simulation showed good agreement with experimental values. Using the selective permeation film can suppress the maximum temperature of a laser rod to 68%, as well as the thermal stress. 9 figs., 2 tabs.

    An apparatus is developed to establish a system which allows utilization of hydrogen safely and easily, and its applicability to a hydrogen system for domestic purposes is tested. The system converts solar energy by the photovoltaic cell unit into power, which is used to generate hydrogen by electrolysis of water at the hydrogen generator, stores hydrogen in a metal hydride , and sends stored hydrogen to the burner and fuel cell units. It is found that a hydrogen occluding alloy of LaNi4.8Al0.2 stores hydrogen to approximately 80% when cooled to 20 to 25degC, and releases it to 10% when heated to 40degC. The fuel cell uses a solid polymer as the electrolyte. The hydrogen gas burner is a catalytic combustion burner with a Pt catalyst carried by expanded Ni-Al alloy. The optimum distance between the burner and object to be heated is 22mm. High safety and fabrication simplicity are confirmed for use for domestic purposes. The system characteristics will be further investigated. 4 refs., 8 figs.

    Dynamic force on blades in a large wind mill changes with rotational speed for various reasons, such as wind shear that causes vertical distribution of wind velocity or titling angle. Therefore, a 2-blade system on a teetered hub is a practical selection for the coned, down-wind type. Use of teetered axis greatly reduces bending moment in the flap direction and that at the axis of rotation. An attempt was made to understand dynamic loads by inertial force resulting from oscillation of the blade rotating on the teetered axis, and thereby to avoid them. The in-plane load can be diminished to zero when the teetered axis is coincided with the center of gravity, but generally cannot be avoided when the blade is strained significantly, except it is operated at the rated condition. The in-plane load and bending moment can be avoided, when rotational freedom is given around the y axis. Dynamic load on a down-wind rotor can be avoided by use of universal joint. 3 refs., 6 figs.

    With an objective of developing a room heating system utilizing a solar chemical heat pump, an experimental system was fabricated to evaluate its performance. Steam was employed as a working gas, and for a reaction material, calcium-chloride was used, which has a reaction temperature zone permitting safe use and fitting the purpose among other hydrate systems and has high standard enthalpy in hydration. Water was used as a solar heat transferring medium. The system operates under the following principle: a container I is filled with hydrated salt and a container II with water, the two containers being linked with a pipe interposed with a valve; heat is inputted and outputted by performing charging and discharging alternately; and the role of a heat pump is played by deriving from environment the heat of water evaporation in the container II during discharging. The COP must take into account the electric power consumption of the water circulation pump to transfer solar heat. A COP of 0.256 was derived as a result of the experiment. 3 refs., 5 figs.

    Attention is paid to reduction in area required for solar cells by solar concentration as a means of solving cost limits of solar cells and unstable supply of Si materials. Low concentration solar cells are effective from the aspects of utilization of scattered light and unnecessary ray tracing. The optical concentration ratio was calculated of three-dimensional lens having design values of various north/south and east/west direction allowable incidence half angles. The three-dimensional lens are designed by cutting a rectangular parallelepiped by the two-dimensional composite elliptical plane designed by various allowable incidence half angles from two directions of north/south and east/west. Using Perez`s sky solar radiation models and meteorological data HASP, calculated were the annual accumulated global radiation ratio on an inclined surface and the optical efficiency. Calculated were the solar cell area ratio and solar concentration area ratio of the concentration type to obtain solar radiation the same as that of the planar type. From the optimization calculation, it was found that lens are optimal which have design values of north/south and east/west direction allowable incidence half angles of 30-70deg. The solar cell area ratio is 57% and the solar concentration area ratio is 1.2 times. It was found that by making the module area 1.2 times, more than 40% of the solar cells used can be saved. 5 refs., 8 figs.

    Estimation of the maneuvering performance of ships is very important from the viewpoint of safe navigation. Using three types of VLCCs (SR221A, B, C) with locally different stern frame lines as computational models, the estimation method of hull hydrodynamic force in turning motion was studied theoretically taking frame line shapes into account. The unstable behavior of courses was also studied using linear differential coefficients obtained from the estimation result on hull hydrodynamic force in oblique navigation and turning motion. As a result, the estimation result on hull hydrodynamic force was slightly different quantitatively from model test results in a range of large drift angle or turning angular velocity, while that was relatively well agreed with test results in a range of small such angle and velocity. As the study result on the unstable behavior of courses by using linear differential coefficients obtained from the estimation result on hull hydrodynamic force, determination of a course stability was possible by considering local difference in hull shape. 4 refs., 8 figs., 1 tab.

    For the purpose of grasping the present situation of the development/production/spread of welfare apparatus in north Europe, an investigation was conducted paying visits to Sweden and Denmark. Basically in the Swedish policy for handicapped persons, disablement is defined not only as features which belong to each individual, but as problems arising when the environment surrounding each individual touches one another. Moreover, characteristics of their policies on welfare apparatus are that major welfare apparatus can be provided for the disabled free of charge, and that the government and public organs play a major role in each step of the development, evaluation, distribution and provision of welfare apparatus. Features of the market of welfare apparatus are that users and buyers of the apparatus are different persons, that a public corporation called SUB participates in determining selling prices, etc., and that the market reflects needs and requests from users comparatively naturally. The needs for welfare apparatus at the Research Institute of Handicapped Persons are grasped through opinion exchanges with groups of handicapped persons or information exchanges with the technical aid center. 3 refs., 11 figs., 10 tabs.

    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.

    Bottom plates of a hull are subjected to laterally distributing force due to in-plane compression force and water pressure in the ship`s length direction as a result of longitudinal bending in a hogging condition. Because buckling collapse of the hull bottom plates leads directly to longitudinal bending collapse of the hull bottom cross section, the hull bottom plates must have sufficient strength. The present study performs a static elastic large deflection analysis and an elasto-plastic large deflection analysis. It elucidates buckling collapse behavior of a square plate subjected to water pressure and in-plane compression load, and considers limits in application of conventional approximation analysis methods. In the case of a water pressure action, deflection components growing in excess of the buckling load do not necessarily correspond to buckling modes of the case where no water pressure is acting upon. Conventional approximation analysis methods may not be able often to pursue actual buckling phenomena. According the result of an analysis on hull bottom panels of an actual ship, the ultimate strength decreases when the water pressure is large. Compression force in the lateral direction as a result of water pressure acting on ship`s sides affected very little the ultimate strength. 3 refs., 7 figs.

    In the design of various floating offshore structures (FOS), the functionality, safety and amenity of FOSs were examined by estimating responses of FOSs to environmental external forces such as wave, wind and flow. In this paper, the estimation method of drag acting on the whole FOS was established by combining previous study results on hydrodynamic force acting on various bodies such as Reynolds number effect (RNE), 3-D effect (TDE) and interference effect (IE). This hydrodynamic force was also compared with that obtained from the experiment result on a FOS model for TLP to confirm the applicability of this estimation method. The estimation result on the drag coefficient in steady flow by considering RNE, TDE and IE well agreed with experimental one. The drag coefficient acting on FOSs in heaving could be estimated in practically sufficient accuracy by considering drag acting on not columns but only square columns. The estimation result on the drag coefficient acting on FOSs in surging by considering RNE, TDE and IE well agreed with experimental one. 12 refs., 10 figs., 1 tab.

    A cellular wireless device performs signal transmission and receiving using only one assigned frequency because of effective frequency utilization, and therefore, is inconvenient in actual use. For this reason, a cellular wireless device operating on a new principle was developed to make simultaneous two-way calls possible on one frequency. The operation principle is such that one frequency is used, voice signal is divided on the transmission side at every 0.4 second, compressed in time to 1/2, and transmitted in 0.2 second upon modulation; and the receiving side extends the signal to a double length upon demodulation to take out the original voice signal. Thus, the transmission time is reduced to half, and the remaining half time thus obtained is assigned to the receiving time from a caller in the similar method to perform a two-way simultaneous call. Both hands can be used freely during a call, making the safe call possible even while driving a vehicle or performing a work. High confidentiality can be maintained by means of voice processing, compression, and extension. Size of the device was reduced, reliability and clarity were optimized, and a large number of frequency can be switched easily. Field test have proved that the device meets the criteria specified in the Electric Wave Law. The device was begun of business use in 1992. It can be connected with portable type telephone sets and those used in business compounds. 2 figs.

    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)

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

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

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

    This report summarizes the fiscal 1999 research cooperation project result on coal liquefaction technology. Cooperative FS was made on coal liquefaction technology of Indonesian coal as petroleum substituting energy. To obtain the basic data necessary for the FS, study was made on the applicability of Indonesian natural minerals as catalytic materials. Promising low-cost abundant Soroako Limonite ore showed a high catalytic activity for liquefaction reaction of Banko coal, and an excellent grindability. Improved BCL process including hydrogenation process was promising for production of high-quality coal liquid superior in storage stability with less nitrogen and sulfur contents. Survey was made on the general conditions of Tanjung Enim area including South Banko coal field concerned, and the geological features and coal seam of South Banko coal field which is composed of 3 seams including coal deposits of 6.35 hundred million tons. To study the marketability of coal liquid, survey was made on the current situation of oil, oil product standards, and blendability of coal liquid. Hydrogen for the liquefaction process can be obtained by coal gasification. (NEDO)

    An investigational study was conducted to clarify the adaptable environment and effectivity of technologies of high temperature separation/recovery/reutilization of CO2. In the study, data collection, arrangement and comparison were made of various separation technologies such as the membrane method, absorption method, adsorption method, and cryogenic separation method. With the LNG-fired power generation as an example, the adaptable environment and effectivity were made clear by making models by a process simulator, ASPEN PLUS. Moreover, using this simulator, effects of replacing the conventional steam reforming of hydrocarbon with the CO2 reforming were made clear with the methanol synthesis as an example. As to the rock fixation treatment of high temperature CO2, collection/arrangement were made of the data on the fixation treatment of the CO2 separated at high temperature into basic rocks such as peridotite and serpentinite in order to clarify the adaptable environment and effectivity of the treatment. Besides, a potentiality of the fixation to concrete waste was made clear. 57 refs., 57 figs., 93 tabs.

    In order to improve the performance of a multiblade fan, the effects of three types of suction cones of the fan casing on the fan efficiency and noise are investigated experimentally. The first type of the suction cone is the insertion type, which is inserted into the inside of the fan impeller. The second type is the extrusion type, which extrudes outside from the casing surface. The third type is the combination type of two types. The results of those three types are compared with those of the commonly used suction cone. The followings are made clear: (1) The insertion type and the extrusion type are effective in improving the efficiency and reducing noise. (2) The optimal lengths of the insertion and the extrusion exist. (3) The combination type is more effective in improving the efficiency. (4) The combination type with the skewed cutoff of the fan casing shows the best effect. (author)

    An epidemiological survey survey was performed to elucidate the fungal flora of a dwelling house. The measurements were carried out in an apartment in Yokohama from Jul. 1996 to Dec. 1997. Fungi were isolated from 106 sampling points (the surface of the walls, floors, etc.) with sterile stamps. It was proved that Cladsporium, Penicillium, Eurotium, and Yeasts showed characteristic distribution. Especially Cladsporium was not isolated from the spring to the summer, but increased in the autumn. In addition to the survey, experiments on fungal growth temperature (13, 20, 25, 30, 36, 42 degree C) and water activity (A w 0.75{approx}0.97) were carried out. Cladsporium grew well in 13, 20, 25 and 30 degree C, but didn't grow in 36 and 42 degree C. In addition, the growth activity of Cladsporium was down below Aw 0.91. Eurotium was isolated from under Tatami, where it has an unchanging temperature and relative humidity. Yeasts preferred very high humidity. It was concluded that environmental factors such as temperature and relative humidity related to the growth of fungi. (author)

    Concerning the conversion of serpentine, not only its magnesium component but also silica component, into industrial materials, conditions suitable for the production of porous materials and amorphous silica by acid treatment were evaluated, and the properties of the products were evaluated. The silica resulting from the acid treatment of serpentine comes out in different forms, each reflecting the structure of the parent rock, that is, an amorphous mass of planar particles from antigorite and a fascicular mass of filaments from chrysotile. A microporic structure resulted when a small quantity of magnesium was allowed to remain in the skeleton structure and acid treatment conditions were properly adjusted. Several siliceous compounds were prepared for the purpose of finding use for silica from this rock, and then it was found that high-efficiency production of high-crystallinity compounds was possible and that they were furnished with properties fit for use as materials. Furthermore, study was made about the kaolinite reaction in which serpentine would be directly converted into useful materials. 105 refs., 55 figs., 6 tabs.

    The phenomena that clay or mud is carried away by waves or currents and deposited in approach channels and harbors are called siltation, and hinder often seriously the navigation of vessels and their arrival at as well as departure from wharves, etc.. In this paper, the hydraulic mechanism of siltation in harbors and approach channels in the sea area is chozen in particular, and waves and currents as the external force governing the travel of bottom mud, the properties of sunken mud, the supply source of sunken mud in approach channels, and grasping of the mud sinking mechanism as well as countermeasures against mud sinking are stated mainly centering around the results obtained from the in situ observations at Kumamoto Port and Banjarmasin Port and their mathematical calculations. The bottom mud traveling mechanism has been accepted as a study subject respectively from such wide viewpoints as river engineering, agriculture, environmental engineering, sanitary engineering, chemical engineering and mechanical engineering, and in addition, it has been under study by coastal engineering. Siltation under the wave actions is still in the state of research even in advanced countries in America and Europe. The siltation research in Japan has a short history, but this is the field which must be coped with positively. 19 refs., 17 figs.

    A study is being made on premixed lean diesel combustion (PREDIC) by means of early fuel injection in diesel engines. The PREDIC makes it possible to largely reduce NOx emission, but has such problems as ignition control and increase in THC and CO generation. In order to clarify the relationship between fuel spray characteristics in the PREDIC and properties of gas mixture and exhausts, the present study has investigated spread and internal structure of the spray by means of spray observation experiment using a pintle swirl nozzle. Based on the result therefrom, simulations were used to investigate effects of spatial dispersion characteristics of the spray on properties of the gas mixture and exhausts before ignition. The pintle swirl nozzle forms conical spray having an air layer inside the spray, where penetration is suppressed even under low atmospheric pressure. By forming hollow spray or solid spray in the conical spray, a possibility was indicated that equivalent ratio distribution of the gas mixture can be controlled and NO emission may be reduced. 8 refs., 12 figs., 1 tab.

    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)

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

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

    The 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.

    For the realization of environmentally friendly, sound economic activities and the assurance of a safe and peaceful daily life for people, studies were conducted about comprehensive risk assessment and management techniques to use in dealing with chemical substances. Concerning the above-named management program, a workshop was called, where panel discussion and exchange of views and opinions were held. In the study of overseas technological trends, visits were paid to interested institutes and corporations in Denmark, Sweden, and Germany, where hearings were held over the management and manufacture of chemical substances. Concerning the control of chemical substances, surveys were conducted of the control in Japan and abroad and of the methods that businesses and other organizations followed in meeting the control. It was found that the control was being dealt with earnestly in every country and that chemical substances would stay managed under international collaborative conditions. Efforts were being positively exerted by businesses and other organizations to properly manage and reduce chemical substances and to develop and use substitutes. It was found that measures for handling chemical substances were closely knit into business management. (NEDO)

    It is known in estimating vibration characteristics of a ship that fluid range affects largely a structure. A parameter calculation was performed on node vibration in the vertical direction of a rotating elliptic body such as a ship to investigate the effect of an arranging method of the measurement points upon the result of the analysis. As a result, it is thought that equivalent interval arrangement of 21 measurement points would be sufficient in a lower order side mode of vibrations with less than four nodes. An analysis of calculations performed by arranging measurement points in experimental measurement points revealed that analysis accuracy would not increase even if the number of measurement points is increased if it is done so without considering rotation vector. An experiment was carried out with the number of measurement points increased to verify the above fact, with which the analysis was verified correct. Therefore, as has been forecasted in the previous report, the cause for the analysis accuracy deterioration in a high order mode may be estimated as the effect of the rotation vector. However, since it is not the situation that an analysis considering the rotation vector has been conducted, it cannot be concluded yet that the effect of the rotation vector is the sole cause. 4 refs., 14 figs., 7 tabs.

    Risk assessed structural positions in a pressurized fuselage of a transport-type aircraft applied with damage tolerance design are taken up as the subject of discussion. A small number of data obtained from inspections on the positions was used to discuss the Bayesian reliability analysis that can estimate also a proper non-periodic inspection schedule, while estimating proper values for uncertain factors. As a result, time period of generating fatigue cracks was determined according to procedure of detailed visual inspections. The analysis method was found capable of estimating values that are thought reasonable and the proper inspection schedule using these values, in spite of placing the fatigue crack progress expression in a very simple form and estimating both factors as the uncertain factors. Thus, the present analysis method was verified of its effectiveness. This study has discussed at the same time the structural positions, modeling of fatigue cracks generated and develop in the positions, conditions for destruction, damage factors, and capability of the inspection from different viewpoints. This reliability analysis method is thought effective also on such other structures as offshore structures. 18 refs., 8 figs., 1 tab.

    Considering integrated hull and piping design in shipbuilding industry as a good example for concurrent engineering (CE), discussions were given on a computer aided method to perform integrated hull and piping design smoothly. When CE aiding by means of a computer is considered, it is important to discuss a method for information management not only for `utilization of product models`, but also for `maintaining consistency between items of product information` and `concurrent utilization and production of product information` in concurrent designs. For the CE aided information management, utilization and production of the product information is effective if restrictive relationship between items of product information, and design functions are made clear. Definitions were given on the restrictive relationship between items of product information and `restrictive relationship information` that has `decision/provisional decision`, `date and time`, `designer` and `design functions`. Furthermore, `comprehensive relationship between items of product information` that can be produced from the restrictive relationship information was defined as a `restrictive network`. Utilizing the restrictive relationship between items of product information for CE aiding is effective. 9 refs., 14 figs.

    The water vapor adsorption desorption isotherms of purified and/or synthesized sepiolite, allophane, diatomite, selectively leached kaolin and mesoporous silica were measured to develop humidity control materials in living environments. Based on Kelvin's capillary condensation theory, suitable pore diameters for controlling relative humidity at 40 and 70% were calculated to be 3.2 and 7.4 nm, respectively. Wakkanai diatomite, purified allophane, selectively leached kaolin and mesoporous silica have suitable pore diameters and high water adsorptivity, and were considered as candidates for humidity self-control materials. Among these materials, mesoporous silica formed as a tile showed the best performance as a humidity control material in desiccator and model house levels. (author)

    Various problems on intelligent planning (IP) and the tendency of basic technology were investigated. For each technique of IP, a Petri net and mark graph have been widely used as the modeling and analysis methods of a discrete event system. Moreover, various planning problems were modeled by a traveling salesman problem, and the efficient solution of the traveling salesman problem has been studied simultaneously. The tendency of the basic technology and application system viewed from an example of intelligent plant planning was investigated as an applied field of planning technology, with importance attached to the production system and robot planning. In the scheduling technology of the production system, the activation of an AI study and a new theory (i.e., architecture study) based on natural science information was investigated with the transition in the world as a trigger. A robot system has been planned in a wide range such as the environmental information acquisition planning of a robot. 202 refs., 69 figs., 4 tabs.

    For the purpose of contributing to the environmental management in Indonesia, Japan made R and D of a laser radar to measure the urban air pollution and an environmental network jointly with Indonesia in compliance with the actual situation of the country. At present, in developing countries, air pollution is becoming a big problem because of increases in population and in energy consumption in urban areas according to the industrial/economic growth. As for the laser radar, it is an active sensor with laser as light source and can observe in high resolution the three-dimensional space distribution such as density and composition of air pollutants. Japan is a leader in the development of laser technology which is a core technology for the laser radar and the preceding research. The equipment is installed at several points of urban areas in Indonesia, and at the same time, the observation network is constructed to collect, analyze and process data at the central processing center. This is a 4-year plan from fiscal 1993 to 1996. In fiscal 1995, negotiations with Indonesia and field surveys were conducted to determine sites for installation. A plan for system improvement was also decided on. 38 refs., 24 figs., 14 tabs.

    Wastewater reuse can be considered as a type of water resource development which is expected to improve the aquatic environment, as well as the stability and reliability of municipal water supply systems. To this extent, wastewater reuse has been taken into account in the planning of water supply systems in several Japanese cities. However, to date the effect of wastewater reuse on water supply system stabilization has not been discussed quantitatively, and the relation between waster water reuse rate and water supply system stability has not been analyzed. In this study, a stochastic model has been presented to evaluate the stability of water supply systems with optimal wastewater reuse rate. Some theoretical analyses and numerical studies were performed, and all of the results have shown that the model is reliable for not only basic studies on water supply system stability, but also for practical use as well. 5 refs., 5 figs., 3 tabs.

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

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

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

    In response to demand for the expansion of living space, the living environment of semi-underground room has been investigated. An attached green house (passive solar house) is adjacent to the semi-underground room. This is reinforced concrete construction, having flat type solar collector on its roof and lighting window in its north side. It does not have artificial air conditioners. Based on the measurements of daylight factor, artificial lighting is not required at the window in the daytime, but it is desirable to use daylight and artificial lighting together at the center. The performance of sound insulation depends on the high performance soundproof sash level. There is less daily temperature variation due to its large heat capacity, and less yearly temperature variation than the outside. By shielding the solar radiation, the insolation in the green house in summer can be restricted in the same as in winter. The insolation can be easily received in winter due to its large vertical intensity of solar radiation. The green house in the south side is useful for improving the living environment of semi-underground room. The temperature rise in the semi-underground room can be restricted by opening window in summer. It is desirable for the comfortable living to use artificial cooling to reduce the daytime temperature by 3 to 4{degree}C. In winter, it is comfortable to heat by 4 to 5{degree}C. 2 refs., 7 figs.

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

    Two kinds of typical environmental learning methods(direction and distance learning and route learning) were conducted experimentally as methods of environmental cognition in unfamiliar areas. Then, aspects of maintaining the sense of direction in grasping space structure of the area environment as well as concrete alternative wayfinding behaviors considered to be behavioral indexes for cognitive mapping were investigated. At the starting point, instruction related to the direction was given to P group, and that related to the route was given to M group. As a result, both groups decided the direction or found the alternative route according to the obtained information. The P group decided the direction properly by grasping the whole directional relations of the area and space structure of the route there. However, it was difficult for them to find the alternative route after restructuring the relations between specific points of the route. Concerning the motor relevant representation of the M group by time-dependent understanding of the route, continual occurence of perceptual characteristics on the way was worth noticing. 13 refs., 8 figs., 6 tabs.

    Equisetum was noted as a plant adaptable to stringent environment referred to as the water level varying part of a reservoir, and was used for afforestation trials. The afforestation trials were performed at the reservoir of Uryuu Dam No. 1 and the regulating reservoir of Moiwa Dam of Hokkaido Electric Power Company. Although the rate of water level variation is small at Uryuu Dam No. 1, it is necessary for Equisetum to withstand submergence and drought for an extended period of time. Moiwa Dam has high water level variation rate, but its water depth is small, and the reservoir is free of long-term submergence and drought. As a result of long-term observation from 1993 through 1997, Equisetum was found having grown well at lower altitude part with higher submergence frequency. It has grown favorably even in parts where submergence rate reaches about 80%. However, at higher altitude with submergence rate of 10% or lower, decrement trend was seen. At Moiwa Dam, Equisetum was all buried in accumulated sand and earth, revealing that such an environment is unsuitable for Equisetum as the one subject to effect of sand and earth that flow in during freshet.

    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.

    Research, development and evaluation were performed with an objective of establishing the basic processing technology and ultra-precision machining device technology utilizing large output excimer laser and high density ion beams. With regard to the large output excimer laser technology, the short wavelength excimer laser life extension technology has demonstrated ong-life operation of 1.02 times 10{sup 9} shots exceeding the final target at the initial laser output of 105 mJ/pulse. With respect to the high-density ion beam technology, the gas phase converged ion beam technology has achieved an ionic current density of 2.5 {mu}A/sr. and a beam current of 25 pA. Regarding the ultra-precision machining device technology, a large ultra-precision grinding machine of five shaft control type was developed as a final target demonstrating machine, which exhibited the shape accuracy of 0.7 {mu}m and surface roughness of 3.45nm. The surface roughness satisfied the final target.

    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.

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

    This paper describes the fundamental experiments for creating property-gradient polymer electrolyte for rechargeable lithium batteries. The rechargeable lithium battery is composed of an anodic composite agent section with high ion conductivity, a separator equivalent section with high mechanical strength (high bridging degree), and a section surpressing the precipitation of metal lithium by contacting with it. The continuous property-gradient polymer electrolyte was tried to be synthesized by means of the plasma polymerization method. As a result, plasma polymerization electrolyte with high ion conductivity could be prepared from the liquid phase by using a monomer with low vapor pressure. Porous material simulating the anodic composite agent was impregnated by the monomer, which was plasma-polymerized. As a result, it was found that the bridging degree decreased from the surface towards the inside of the plasma-polymerized porous material. In addition, polymer was prepared using fluorine-base monomer. Thus, LiF thin film could be prepared through the reaction between the polymer and metal lithium. 3 figs.

    Studies are made to define the working mechanism of semiconductor photocatalysts such as TiO2 and to establish designing guidelines for improving on their activity and functions. TiO2 in the air actively produces oxygen seeds for the oxidation and removal of NOx, etc. It is desired that a catalyst have a specific surface area large enough to retain the product of its action. To meet the need, a thin-film photocatalyst which is an aggregate of TiO2 crystals is produced by burning a film of a sol/gel system of reaction doped with macromolecules. This product has a larger specific surface area and is higher in pollutant-removing performance, and may be put into practical use. In another experiment, metal-carrying particles TiO2 suspended in water are employed for the reduction of CO2. Though the main product of catalysts carrying Pt or Pd is methane, a photocatalyst carrying RuO2 produces acetic acid mainly and loses less activity with the passage of time. A hybrid photocatalyst is composed of an organic pigment and inorganic semiconductor, synthesized through a covalent bond between a sililated-surface thin TiO2 film and porphyrin. It is confirmed that the newly developed process brings about an increase in electron migration efficiency. 3 figs.

    This paper describes the research and development of power generation system by means of chemical-looping combustion. For this system, fuel flows in a reduction reactor and air flows in an oxidation reactor. These two flows are separated. As a result, recovery of CO2 without energy consumption, drastic improvement of power generation efficiency, and suppression of NOx emission are expected. To realize the above, two promising candidates, NiCoO2/YSZ and NiO2/NiAl2O4, have been found as recycle solid particles between the both reactors. These have excellent oxidation/reduction cycle characteristics. By these particles as well as the existing particle, NiO/YSZ, practical application of the chemical-looping combustion is realized. Besides LNG, coal and hydrogen were considered as fuels. When using coal or hydrogen, it was found that temperature of the reduction reactor should be increased the same as that of the oxidation reactor. This is a different point from a case using LNG as a fuel. 5 refs., 2 figs.

    Design engineering and experimental study were made of precast PC clad connection. The clad connection method between the columns and beams is classified into bracket method, shearing key method, corbel method and reinforcing structure-jointing method, among which the corbel method is recommendable because of its simplicity without slip. The PC clad connection system is characterized by its possibility of structuring the continuous multi-rahmen structure, designing the highest strength concrete and easing the earthquake-proof design with a high toughness restoring force. The PC cable wiring method is classified into X-cross method and continuous method. The design of PC clad connection was experimentally proved by alternately loading the frame. Through the experiment, the interstory deformation angle, and stress behavior of the column and beam PC steel materials were made clear so that their destruction became able to be prevented. Also through the experiment, the interstory deformation angle and maximum column-shearing force were known at the yield point of beam, which had the frame-restoring force characteristics modeled by a trilinear elastoplastic type. 28 refs., 13 figs.

    Cable-stayed bridges are being constructed increasingly and their maximum effective span length is becoming longer to the extent that it is about to reach the limit, thereby diagonal members which, by nature, tend to vibrate become much longer, hence problems concerning vibration have drawn attention. In this article, regarding vibration insulating rubber for absorbing vibrations to be set at an anchorage of diagonal members, a new mechanism has been invented and its analysis as well as demonstration experiment have been conducted. This mechanism is based on the concept that the vibration insulating rubber has been set beforehand at the time of installing the diagonal members, adheres to the diagonal members immediately after the diagonal members are stretched, but its adherence is released simply when tension adjustment is needed, and the spring constant of the rubber can be calculated simply within the range of practical use. The results obtained from the above analysis and demonstration experiment are as follows; it is necessary to set vibration insulating rubber in the vicinity of the anchorage of diagonal members in order to absorb vibrations of the members and the method to make its setting simple and secure has been confirmed. Also the calculation method of spring constant of vibration insulating rubber necessary for estimating the secondary bending stress of diagonal member has been confirmed, thereby designing of vibration insulating rubber has become easy. 8 refs., 14 figs., 2 tabs.

    On the insert reinforcing bar structure for the connecting part of the main tower of cable stayed bridges, this paper reports verification results on a load resistant safety with a full-scale model, structure analysis and construction work. The basic structure was composed of a drilled steel shell, inserted reinforcing bars, fixing structure of bars in lining concrete of the shell and a pressure bearing plate. As an experimental result, the connecting part had a sufficient load carrying capacity against both tensile and compressive loads. The shear stress of the insert reinforcing bar structure was estimated successfully under von Mises`s condition. The shear spring constant in deformation characteristics was linearly proportional to an inserted reinforcing bar ratio. In earthquake, nearly 60% of an allowable compressive load was transferred to concrete through the pressure bearing plate. The analytical results of load resistant deformation characteristics of the connecting part well agreed with experimental ones, and the proposed analytical model was applicable to estimation of a dynamic behavior. 5 refs., 22 figs., 4 tabs.

    Thin-walled box stub columns such as beams of cable-stayed bridge, suspension bridge tower, arch rib of arch bridge and steel piers and so forth can also bear torsion at the same time besides compression and bending. These thin-walled box stub columns may achieve ultimate condition before reaching to plastic condition due to the effect of local buckling and so forth. Accordingly, it is the important topic to study the properties regarding ultimate strength of thin-walled box members in order to evaluate correctly the effect on load bearing resistance of local buckling. In this report, validity of load bearing resistance curve and ultimate strength interaction curve proposed by authors was studied using load bearing capacity experiment results. As a result, all ultimate strengths obtained by the experiment were higher than the ultimate strengths estimated by load bearing capacity curve and ultimate strength interaction curve. Further, it was revealed that the specimens subjected to torsion or subjected to bending and torsion and so forth exceeded the plastic strength due to the effect of strain hardening. 12 refs., 14 figs., 4 tabs.

    To further enhance resource/energy conservation and environmental impact reduction, it is necessary to develop innovative chemical reaction process technologies. It is for this reason that 'development of next-generation chemical reaction process technologies' is being carried out under the New Sunshine Program. The survey and research, for the fulfilment of the above goal, aim to select important technologies and put in a easy-to-study order the problems contained in associated technologies for picking out tasks for future studies for the purpose of suggesting some subjects to be taken up for future development. In addition, studies are made about how a comprehensive technology assessment system should be. In this fiscal year, propositions are compiled for research and development projects on five subjects. Studies of subjects other than these five will also continue to eventually build concrete propositions on them. The said five subjects involve 1) the development and application of nonaqueous biotechnologies, 2) biotechnology-aided polymeric material creation processes, 3) construction of high-efficiency energy conservation processes using innovative grain handling technologies in the high-temperature reaction field, 4) manufacture of high-performance polymeric materials for batteries and development of battery fabrication processes, and 5) the development of an energy conservation process maximally utilizing environmentally-friendly polyolefin.

    The task with operating highly functional and intelligent machines, is supposed to cause the mental stress such as tension, anxiety or fear, owing to the operation itself and movement of the machines. The purpose of the project is to establish the physiological sensing technique in objective measurement of the various mental stress caused by the operation or the movement of machines, aiming at designing the optimal interfaces in man-machine system. Subjective quantities and physiological responses are measured, under the stresser of five different conditions, such as a monotonous task, a task which causes tension, and a motion of a robot which causes fear. BP, ECG, and are measured as Physiological items. More precisely, the variation in systolic pressure, RRI of heartbeat or LF/HF value obtained by its spectrum analysis, and the power spectrum of a wave or CNV area derived from spectrum analysis of EGG, are obtained for each item. The results of the experiment show that subjective responses such as irritation, tension and concentration due to the increase of the task load, and fear caused by the movement of machines, are able to be measured by physiological responses such as BP, ECG and EEG.

    Considering integrated hull and piping design in shipbuilding industry as a good example for concurrent engineering (CE), discussions were given on a computer aided method to perform integrated hull and piping design smoothly. When CE aiding by means of a computer is considered, it is important to discuss a method for information management not only for `utilization of product models`, but also for `maintaining consistency between items of product information` and `concurrent utilization and production of product information` in concurrent designs. For the CE aided information management, utilization and production of the product information is effective if restrictive relationship between items of product information, and design functions are made clear. Definitions were given on the restrictive relationship between items of product information and `restrictive relationship information` that has `decision/provisional decision`, `date and time`, `designer` and `design functions`. Furthermore, `comprehensive relationship between items of product information` that can be produced from the restrictive relationship information was defined as a `restrictive network`. Utilizing the restrictive relationship between items of product information for CE aiding is effective. 9 refs., 14 figs.

    Risk assessed structural positions in a pressurized fuselage of a transport-type aircraft applied with damage tolerance design are taken up as the subject of discussion. A small number of data obtained from inspections on the positions was used to discuss the Bayesian reliability analysis that can estimate also a proper non-periodic inspection schedule, while estimating proper values for uncertain factors. As a result, time period of generating fatigue cracks was determined according to procedure of detailed visual inspections. The analysis method was found capable of estimating values that are thought reasonable and the proper inspection schedule using these values, in spite of placing the fatigue crack progress expression in a very simple form and estimating both factors as the uncertain factors. Thus, the present analysis method was verified of its effectiveness. This study has discussed at the same time the structural positions, modeling of fatigue cracks generated and develop in the positions, conditions for destruction, damage factors, and capability of the inspection from different viewpoints. This reliability analysis method is thought effective also on such other structures as offshore structures. 18 refs., 8 figs., 1 tab.

    It is known in estimating vibration characteristics of a ship that fluid range affects largely a structure. A parameter calculation was performed on node vibration in the vertical direction of a rotating elliptic body such as a ship to investigate the effect of an arranging method of the measurement points upon the result of the analysis. As a result, it is thought that equivalent interval arrangement of 21 measurement points would be sufficient in a lower order side mode of vibrations with less than four nodes. An analysis of calculations performed by arranging measurement points in experimental measurement points revealed that analysis accuracy would not increase even if the number of measurement points is increased if it is done so without considering rotation vector. An experiment was carried out with the number of measurement points increased to verify the above fact, with which the analysis was verified correct. Therefore, as has been forecasted in the previous report, the cause for the analysis accuracy deterioration in a high order mode may be estimated as the effect of the rotation vector. However, since it is not the situation that an analysis considering the rotation vector has been conducted, it cannot be concluded yet that the effect of the rotation vector is the sole cause. 4 refs., 14 figs., 7 tabs.

    The influences of fish (goldfish) on water quality and nutrients cycle (carbon, nitrogen, phosphorus) were investigated during 39 days in the summer of 1993, using six outdoor experimental ponds (36 m{sup 3}) with the same water residence times and nutrient inputs. Blue-been algae dominated the ponds with fish. Compared with ponds without fish, the ponds with high densities of fish had standing stocks of zooplankton and macrozoobenthos nearly one order of magnitude lower, about twice the concentrations of chlorophyll a and twice the rate of primary production. Settling rates of particulate substances in the high density ponds were nearly half those observed in ponds with no fish. The processes of sedimentation and exchange with air played important roles in the nutrient budgets as well as the in- and outflows and the changes in nutrient standing stocks. The high concentrations of chlorophyll a in the fish ponds were attributed in part to the lower zooplankton grazing pressure and in part to the higher nutrient concentrations due to lower settling rates and rapid nutrient recycling between biomass and dissolved components. 28 refs., 8 figs., 6 tabs.

    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.

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

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