    Microorganisms are cultivated industrially in a great quantity to fix CO2 at efficiency higher than that of photosynthesis in natural world to develop technologies to re-utilize them as resources. This paper describes achievements in fiscal 1998. Existing strain samples of photosynthesized bacteria and micro-algae were screened to continue discussions on optimal culture conditions, and evaluation on properties. Genes that provide Chlorella with antibiotic resistance were introduced to have performed evaluation on function manifestation, and acquired enzymatic genes of unsaturated {omega} 3. Using green algae as the object, reduction in the processing time has resulted in acquiring a large number of fused cell colonies. Discussions were given on conditions to breed photosynthesized bacteria and fix CO2. Structural analyses were performed on CA protein as an enzyme related to take CO2 into living organisms, and on genes. Developments were carried out on a photosynthesizing bio-reactor and useful substance producing technologies on a continual basis. A 200-liter scale light collection type bio-reactor improved the fixing capacity by 30% in Chlorellas by changing the culture medium. The direct light receiving panel type bio-reactor can utilize even scattered light, with its fixing capacity per installation area exceeding the target. Fundamental data were acquired with Chlorellas on utilizing feeds, fertilizers and building materials. (NEDO)

    Chemical sensor is made of up transducer that transfers the part and signal recognizing the measurement objects. Biosensor that normally transfers the amount of chemicals into electrical signal is a sensor in which living materials like enzyme, microorganism or antigen, antibody and so forth are used in the recognition part. Recently, the structure or the function of the living materials is clarified gradually with the significant progress in biofeedback, however, the synthesis of artificial material having same function as that of living materials is extremely difficult. Accordingly, it is very practical to develop high degree sensor function by using living materials with developed function in material recognition part, an important element of the sensor. In this report, solid state biosensor using electrode as a transducer is focused, and specially, recent research progress regarding the amperometric measurement which measures oxidation/reduction current is discussed. 35 refs., 8 figs., 1 tab.

    In the conversion from solar energy into chemical energy (fuels) by photochemical conversion, an electron donor is necessary since all the fuels are reductive compounds. From the viewpoint of economic profit, water is the only one candidate as a cheap compound and existing impartially. In this paper, photosynthesis as well as the realization of its artificial model, and the relevant basic research executed recently aiming at the construction of an artificial photosynthetic system are explained. The main reaction of photosynthesis is the generation of carbohydrates by the reduction reaction of carbon dioxide with water as an electron donor and solar visual light as an energy resource. As a special example thereof, the UV photolysis of water due to the photocatalysis of a micro-particle system is introduced. The method of using a semiconductor and the method of using sensitizes are described as the photo excitation system when designing the artificial model. Additionally, as the research with respect to the construction of an artificial photosynthetic system, a photo-exciting charge transfer system is introduced. 27 refs., 1 fig.

    For this survey, the latest technology trends relating to microbial functions are summarized to recover and effectively utilize CO2, typical greenhouse effect gas, using microbial functions. Systematic survey and analysis are conducted concerning the microorganisms useful for fixing CO2, CO2 uptake mechanism during the microbial reactions, utilization methods of solar light and useful energy sources except solar light, highly efficient production of useful materials, and usage of produced useful materials. Research has concentrated on use of biological activities for this purpose through design of bioreactors using microorganisms (bacteria and microalgae) for efficient CO2 fixation. For the process to have net CO2 fixation as assessed by its life cycle and to make the process economically feasible, it is essential not only to fix CO2 merely in the form of biomass but in addition to convert it to useful materials by the catalytic activities of the organisms. Three categories were set for the survey, i.e., microorganisms with CO2 fixation ability, available energy for CO2 fixation, and target CO2 fixation products. 169 refs., 49 figs., 14 tabs.

    The trend of technology is surveyed from a standpoint that, in the process of CO2 fixation using microbes for the production of useful substances, it is essential, in view of income/outgo balance and economy, to utilize their catalytic function. The survey centers about the feasibility of the utilization of organic wastes, cellulose wastes in particular, as an energy source. Special attention is paid to the energy of artificial light and laser beams. From a point of view that it is important to suppress cell multiplication and to effectively utilize only catalytic activity for the production of useful substances, the cell division mechanism of the Corynebacterium is analyzed, and the findings are compiled to facilitate the study as to whether the division may be controlled. A report is also prepared on the metabolic mechanism of a photosynthesizing bacterium that is judged to be the most promising species. Reference is made to aerobic and anaerobic bacteria. Shown are the organic compounds that are formed by CO2 gas fixation thanks to microbial or enzymatic reactions. To emphasize their importance as an energy source and to explain the conversion of biomass into useful substances, the technology and economy of conversion into fuel compounds are surveyed. The production of ethanol out of organic wastes is evaluated in the way of LCA (life cycle assessment). (NEDO)

    Basic research was made on establishment of a bioassay for testing the effect of deep water on surface biota. Mixing of surface water and deep water with high-concentration nutrient salts has effect on fine algae (phytoplankton) immediately. In this research, based on conventional AGP (algae growth potential) method as water quality evaluation method by fine algae, the multiplication potential of 13 strains of algae in Kochi's and Toyama's deep water was evaluated by using the increase rate of the number of cells. The research result showed that (1) deep water has the potential increasing cell concentrations of every fine algae to several times or over ten times as compared with surface water, (2) most of both nitrogen and phosphorus in deep water are consumed during the above process, (3) cell concentrations of both harmful and usable species increase, and (4) although no difference in mean potential is found between Kochi's and Toyama's deep water, the patterns of strains promoting multiplication are different between them.

    For the removal and recycle of CO2, a global warming gas, utilization of photosynthesis by micro algae is investigated. Formed micro algae are decomposed into CO2, H2O and CH4 again, which does not result in the permanent fixation. For the effective utilization of these micro algae, creation of petroleum alternate energy was tried through the co-liquefaction of micro algae with coal. Were investigated influences of the reaction temperature during the co-liquefaction and influences of catalysts, such as Fe(CO)5-S, Ru(CO)12, and Mo(CO)6-S, which are effective for the coal liquefaction. Micro algae, such as chlorella, spirulina, and littorale, and Yallourn brown coal were tested. It was found that co-liquefaction of micro algae with coal can be successfully proceeded under the same conditions as the liquefaction of coal. The oil yield obtained from the co-liquefaction in the presence of Fe(CO)5-S, an effective catalyst for coal liquefaction, agreed appropriately with the arithmetical mean value from separate liquefaction of coal and micro algae. It was suggested that pyrrhotite, an active species for coal liquefaction, was sufficiently formed by increasing the addition of sulfur. 2 refs., 7 figs., 1 tab.

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

    For measures to deal with aerodynamic noise, recent subjects were put in order and some examples of the studies were introduced in this paper. Aerodynamic noise can be classified into rotational aerodynamic noise such as jet engine fans or helicopter rotors and general aerodynamic noise such as high speed jet noise, high speed air flow inside piping, and external noise from vehicles, cars and aeroplanes. The aerodynamic noise of the air flow radiated from a wind tunnel exit was caused more or less by the pressure fluctuation of a boundary layer in a high frequency wave region. In checking the noise generated from a difference in level, projection, cavity, opening, etc., of a high speed vehicle in a wind tunnel test, the noise was louder in the case of a difference in level where the downstream side was raised. The finding was similar with projections. In the rear of a super sonic choke part, a strong flow was generated and became a violent noise source when a flow was overexpanded and a pressure was recovered with a sonic boom. However, the noise was greatly reduced by installing a porous material such as a porous metal immediately behind the choke part. An active control of noise was carried out by changing a sound field characteristic against aerodynamic self-excited noise with a speaker. 32 refs., 11 figs.

    This paper describes CO2 laser cutting of medium thick plates. Carbon dioxide laser is mainly used for laser generators. The generation efficiency of CO2 laser is 5 to 15% which is higher than that of the other lasers. Ninety percent of the usage is for cutting, piercing and welding. Laser cutter having a separated generator with a power from 3 to 6 kW is often used for cutting medium thick plates. The recent trend of new cutting technology is introduced. When power is increased from 3 kW to 6 kW without using oxygen as assist gas, the cutting thickness of stainless steel plate increased into 1.5 times, and the cutting speed increased into 1.5 to 2 times. For the soft steel members with black coating in which the power-up effects have not been obtained, the cutting speed, quality of cutting surface and cutting stability were improved by introducing new technology. Piercing time has been reduced by developing a method by which pulse generation is changed during piercing and a method by which piercing is conducted by irradiating the maximum power of continuous generation. Cutting quality with high accuracy has been realized by developing light weight generator and high performance NC unit. 10 figs.

    Recent trend of CO2 laser cutting is described. The cutting speed has increased five times in these seven years, and cutting is now performed at 8m/min for a hole that satisfies a circularity of 50{mu}m. In the low-speed domain, again, cutting accuracy is as high as 20{mu}m. In the cutting of thick plates, laser encounters some difficulties, which include the increased thermal load on optical parts and devices in the oscillator, lessened cutting condition tolerance, variation in the accuracy of products, difficult cutting, etc. Discussed in this report are measures for correcting factors affecting product quality with reference taken to a thick soft steel plate. A laser beam emitted by an oscillator is condensed by and projected through a condenser lens, and the condensing capability is affected by various factors, such as the beam mode order, beam diameter, and focal length, etc. What is important is to find out the optimal conditions. The assist gas has to satisfy certain conditions because it assumes an important role in controlling the discharge of molten metal from cut grooves, heat generated by oxidation reaction, and cooling. The properties of the material to be cut also exert some influence. In the case of thick plate cutting, the cutting capability is governed by the geometry to be fabricated. Also employed for the prevention of poor jobs due to improper condition switchover and cutting routes is an optimal cutting condition control technique. 3 refs., 12 figs.

    A biological reduction method in which hazardous hexavalent chrome is reduced by bacteria is explained as one of the bioremediation technologies. Those bacteria are separated from active sludge in the urban sewage treatment plant. The hexavalent chrome-reducing bacteria were isolated by cultivating the sludge. They were Enterobacter cloacae which are intestinal bacteria. Then, they were named HO1 stock. As a result of analyzing the reduction mechanism, it was made clear that the function is localized in the cellular endosporium and that the reduction is made by utilizing the electronic transfer system of endosporium. Under both aerobic and anaerobic conditions, they convert the hexavalent chrome into the trivalent chrome outside the cells. As a result of test, it was known that 5mM hexavalent chrome can be treated in one day. A quick reduction was confirmed also through an experiment in which carbon source was added to the industrial wastewater. If used for the treatment of sludge/water contaminated by hexavalent chrome, the present reduction by bacteria has the following advantages: The highest reduction rate is given near pH=7 at ordinary temperatures. It is not necessary to add chemicals. Energy is not needed. It is a disadvantageous fact that the present bacteria, if exposed to oxygen, become inactive. 18 refs., 5 figs.

    Inside the jet engine, the propulsion engine for an aircraft, a high speed air current is flowing, and the rotors such as the fan, compress or, turbine and so forth are rotating with a high speed in its flowing current. The flow itself in which a high speed exhaust jet is discharged in the air from engine exhaust port, and the aerodynamic noise generated by an interaction of the flow with the material bodies are the main noise sources of the aircraft engine. Because the supersonic planes are necessary to fly with mach number 2 - 3 during cruising, the turbojet engine with a large jet exhaust speed or the low bypass ratio turbofan engine is selected. Since a noise reduction by reducing the jet exhaust speed, which was an effective measure for the high subsonic speed passenger plane, can not be applied, a reduction of the supersonic jet noise, which is hard to be reduced, becomes a necessity. In addition, in recent years, a research and development of the advanced turbo prop (ATP) aircraft with a further higher thrust efficiency are advanced as well. The aerodynamical noise reduction technologies of these engines for supersonic airplanes are summarized. 14 refs., 11 figs., 1 tab.

    As the main components of the aeroengine, the fan and compressor reach to extremely high level stage technologically. Also at present when about 50 years passed after the jet engine was applied in practice, however, an effort for a modification is being continued, and furthermore even in the 1990s, the engines that adopted the new technologies are in succession being put in practical application. New engines in the 1990s are being applied in practice by adopting the study results on fan and compressor from the 1970s to the 1980s. Because, which way the future fan and compressor of the aircraft will go to has a relation with an aircraft trend from now on, and even in the 2000s the high subsonic speed aircrafts will be a center of the private air planes. The engine of high subsonic speed aircraft in the next generation will become an ultrahigh bypass ratio engine, the thrust efficiency is raised and noise is lowered, by lowering a fan pressure ratio and by increasing an air flow quantity compared with the current high bypass ratio turbofan engine. 16 figs.

    Bacteria such as Zymomonas atracts attention in production of ethanol from carbohydrates in addition to yeast used for a long time, however, Zymomonas ferments only glucose, fructose and sucrose. After searching microbes in the nature with excellent properties in fermentation ability and salt resistance, a new Gram-negative bacterium has been isolated from a certain tree sap which is suitable for production of ethanol from maltose and starch hydrolyzate. The features of cell morphology of the new bacterium are: bacillus, peritrichous, no sport forming, Q-9 in quinone system, and an anaerobic Gram-negative bacterium. It utilizes maltose, sorbitol and maltose and produces [alpha]-glucosidas but no [beta]-galactosidase nor arginine dihydrase. The strain T109 is deposited as FERM BP-3292 to the Industrial Research Institute of Microbiology. 2 figs., 2 tabs.

    Described herein is the method for analyzing quantity of organic carbon synthesized by chemoautotrophic bacterium. It is based on the combustion-infrared spectroscopy, which is normally adopted for quantitative analysis of organic carbon. The problems involved in the measurement of organic compounds synthesized by iron-oxidizing bacteria are noise by culture medium components, aging of gas analyzer and contamination with organic compounds from a silicon plug. The measures taken in this study against these problems include comparison of the results with a medium containing iron-oxidizing bacteria with those with a medium free of these bacteria, calibration with the standard solution for each measurement, and replacement of a silicone plug by a silicon cap. Organic carbon is measured by a TOC-5000 analyzer equipped with an automatic sample feeder ASI-5000. Biomass density is determined by the MPN method. It is confirmed that organic carbon quantity is almost in proportion to biomass density, a phenomenon which can be used to determine organic carbon quantity. 7 refs., 6 figs., 1 tab.

    This effort aims at the development of high-performance bacteria usable in bio-leaching in metal smelting by acquiring genes capable of realizing such. A method is used of choosing some isolated strains exhibiting high-performance traits and acquiring target genes therefrom by use of genetic engineering. Approximately 200 kinds in the aggregate of acidophilic bacteria are currently available for the study, including isolated iron-oxidizing and sulfur-oxidizing bacteria, standard species acquired for the study, and strains previously isolated by the laboratory. The bacteria are tested with respect to their Fe{sup 2+}-oxidizing rates, sulfur-oxidizing capabilities, and strength to withstand inhibiting substances (Ag{sup +}, Cl{sup -}, Mo{sup 6+}, etc.), which results in the nomination of 8 strains. The study planned to follow includes processes involving the extraction of chromosome DNAs from the 8 strains and their refinement, gene cloning by the Southern hybridization method, determination of their base sequences, determination of the difference between the strains in point of gene expression, and investigations of the relations that the results of these processes bear toward the said high-performance traits. Also under way is a study about the infuence-exerting factors revealed during the evaluation of the abilities of acidphlic bacteria. 2 refs., 2 tabs.

    This paper describes a pilot plant study on algae removal of a fluidized bed biofilm reactor system for lake water treatment. The system does not need backwashing because the fluidized bed suffers no clogging. Moreover, the system uses dissolved oxygen in influent water for aerobic biological treatment without aeration equipment. Thus, this system is a low energy and easy maintenance way to purify eutrophic lake water. The system was operated continuously at a flow rate of 1500 m{sup 3}/d{sup 1} for 9 months at Tsuchiura Port in Lake Kasumigaura. In this study, chlorophyll-a and dissolved oxygen in both influent and effluent water were monitored continuously. In summer (August to September) when water bloom occurred, the average removal efficiency of chlorophyll-a was 64% at the average influent chlorophyll-a concentration of 137.8 {mu}g/l{sup 1}. During the total experimental period (9 months), the average daily amount of removed chlorophyll-a was 40.3 g/d{sup 1} at the average influent chlorophyll-a concentration of 89.5 {mu}g/l{sup 1}. By analyzing the relationship between the removed chlorophyll-a and the consumption of dissolved oxygen, it was estimated that almost all of algae trapped in the reactor was degraded biologically. 20 refs., 12 figs., 2 tabs.

    The objectives are 1) development of biological processes needed for the treatment of pollutants and the conversion of resulting biomass to value added products such as energy and fine chemicals, and 2) development of techniques for monitoring of both biological and chemical hazards associated with process operation. We developed a microalgal system for simultaneous removal of CO{sub 2}/NO{sub x} from flue gas, as well as an electro-osmotic method for recovery of microalgal cells. A strategy for effective culturing of photoautotrophic cells in photobioreactors was also proposed. We utilized waste algal biomass to produce biosurfactants, and studied about structure-function relationship of lipopeptide biosurfactants. As an energy product, H{sub 2} was produced via lactic acid fermentation of algal biomass. Physiology of marine phytoplankton was also studied in relation to the future mass production of microalgal biomass. A rapid monitoring of microbial populations was possible by using fluorescent probes. An enzyme immunosorbent assay system specific to fish metallothionein was established for the assessment of aquatic environmental pollution. Human herpesvirus latent infection was effectively applied to biological assay of environmental hygiene. (NEDO)

    The energy structure of semiconductor microcrystals with less than 10nm particle size is different from that of bulk semiconductor, and the reducing force of electrons and the oxidizing force of holes produced by light in microcrystals are larger than those of bulk semiconductor. Focusing on the application of semiconductor microcrystals to photocatalysis, the effects of the particle size and surface conditions of particles on photocatalytic activity are discussed. It has been shown that the change in the characteristics of semiconductor microcrystals depends on particle size, and microcrystals with narrow distribution of particle sized is necessary for the study of the characteristics of semiconductor microcrystals. An example of high efficient progress of CO2 direct reduction by the use of semiconductor microcrystals is introduced. It has been made clear that the photocatalytic activity of semiconductor is improved when a small amount of electrode catalyst is supported in it. A unique photocatalytic reaction which can not be observed with bulk particles can be progressed by the use of high oxidation and reduction ability caused by quantum size effect of semiconductor microcrystals. 26 refs., 2 figs., 1 tab.

    Progress of development in latest shield construction method is startling. Various new construction methods have been developed and applied to constructions, such as a triad multi-shield, a parent-child shield and variable cross section shields for multi micro shield tunnel and square cross section, including a spherical shield. On the other hand, large and long-distance shield constructions have been carried out, such as ones for the Tokyo Bay Highway and Kanda River, which have inevitably accelerated development of automation. Different systems that have been completed, developed and applied to actual constructions include systems for automatic segment transportation and assembling, automatic extension of mud delivery and drainage pipes, automatic excavation control, sheet spreading devices, and comprehensive construction control. Recent constructions tend to require high-speed excavation and work at greater depths, in addition to increase in scale and distance, whereas developed new technologies are increasing diversity. This paper lists in one table new technologies for shield construction methods published in the last decade. It also summarizes representative technologies extracted from the table, looks back over the new technologies used in the Tokyo Bay Highway construction, and describes future prospects on the technologies. 9 refs., 5 figs., 2 tabs.

    Arc synthesis method, which is now the center for the synthesis of new carbon compounds such as carbon nanocapsules and carbon nanotubes, is introduced together with its current status. Many new carbon compounds are synthesized by DC arc discharge heating method (arc discharge method) in which a graphite bar is used as the electrode. C70 and higher order fullerenes having larger carbon numbers are found one after another in the soot produced by the arc discharge method, and the structures of C76, C78, C84, C90, C94, and others have been clarified. It is considered in the arc discharge method that the processes of a large amount of carbon evaporation by high temperature and the succeeding quenching cause to produce various kinds of new carbon compounds. In connection with other synthesis methods, synthesis of fullerenes by incomplete combustion, synthesis of nanotubes by the vapor phase thermal decomposition method, and the synthesis of nanotubes using casting molds are discussed. 24 refs., 6 figs.

    A dynamic programing method was applied for maximizing a production yield in controlling the process of aerobic bacteria fermentation. An optimal control was carried out by air flow rate under a sufficient sugar supply condition, using the bacteria amount as a state variable and the air flow rate as an operation variable, under conditions where the sugar consuming rate is not a limiting factor. The growth and production were modelled, and the relationship of both the specific growth rate and the specific production rate to the specific respiration rate was was expressed as functional tables. A simulation was carried out, which provided an optimum air flow pattern. This relationship between the bacteria amount and the optimum air flow rate was mapped to perform a map control. Conditions other than the air flow pattern were made to agree with the previous empirical cultivation method, and experiments were conducted using a cultivation tank of 0.03 m {sup 3}. A yield increase of 13.6% over the conventional method was attained, thus the reasonability of the modelling was verified. It was found that there are portions where the width of the optimum air flow control is wide and narrow, and it is possible to reduce the number of maps if this this is taken into account. 4 refs., 8 figs., 2 tabs.

    This paper describes VPP (Voluntary Protection Programs) and current administrative strategies of US Department of Labor, OSHA (Occupational Safety and Health Administration). Although VPP is conducted by the Federal Government or the state governments with original VPP, it is properly a voluntary program in which entrepreneurs independently participate. OSHA inspects the content and execution condition of every program based on a VPP standard, and after certifying a business establishment satisfying the standard as excellent one, OSHA excludes it from inspection objects for a certain period. After such a period, reinspection and renewal are repeated. This system is derived from that a voluntary program proposed by constructor of Calif. in 1978 was markedly effective to protect workers from damages. Safety and health problem includes various keywords such as internationalization, new technology, risk assessment, process control, self responsibility, information opening, and diverse policies. Although uniform regal safety and health measures are important, promotion and establishment of activities by workers and entrepreneurs themselves in a field are also important. 8 refs., 2 figs.

    This paper explains groundwater investigating methods, introducing particularly two methods. The resistivity tomography is a method to measure potential distribution generated when current is applied around an area to be investigated. Using the measurement result as projection data, the resistivity distribution is restructured within the area of the investigation. The paper summarizes the measurement method (measuring equipment, electrode arrangement, etc.), the analytic method (establishment of an initial model, and the alpha-center method to calculate theoretical potentials corresponding to the model), and an application example of the method in which the resistivity change was observed using permeation of salt tracers. The resistivity imaging method (two-dimensional resistivity analysis method) is superior in practicability to the above method under the present state of the art. This method does not differ from the conventional resistivity method in methodology, but improves the analytic accuracy over the conventional electrical investigation method as a result of analysis combining the simplified two-dimensional analysis method with the alpha-center method. A summary is given on the measuring and analyzing methods. 13 refs., 10 figs.

    Behavior of bacteria activated in reservoir though molasses-injection-tests, was investigated using the restriction fragment length polymorphism analysis with the polymerase chain reaction (PCR-RFLP) method, for elucidating potential bacteria to suppress in situ growth of microbes to be injected into the reservoir in the microbial enhanced oil recovery (MEOR) process. As a result, some bacteria belonging to Enterobacteriaceae species or their close relative species were grown predominantly in the reservoir, among bacteria inhibiting in the ground-water. The foregoing indicates that behavior of these bacteria in reservoir must be taken into consideration when giving a full account of behavior of microbes to be injected into the reservoir to put the MEOR process into operation. Potential proliferation using molasses to activate those bacteria was also estimated on the laboratory tests, to clarify the growth of microbes to be injected into the reservoir to operate the MEOR process. In consequence, it became clear that these bacteria have a potential growth exceeding 10{sup 8} CFU/ml, utilizing molasses. These facts indicated that microbes to be injected into the reservoir at the MEOR field tests are necessary to grow more excellently than bacteria inhabiting in the ground-water. In addition, as flow, the injection fluid is influenced by reservoir heterogeneity caused by injection of molasses, it was inferred that microbes to be injected into the reservoir at the MEOR field process are also necessary to grow more remarkably than bacteria inhabiting in the reservoir brine at high permeability zones and bacteria inhabiting in the reservoir rock. Furthermore, the results of the functional testing for MEOR conducted in the presence of bacteria activated through molasses-injection-tests indicated the importance of effective use of microbes to be injected, taking into account the characteristics of the reservoir and function for MEOR of those microbes.

    This paper describes biodegradation of organophosphoric acid triesters (OPEs) in water environment, in particular, by aquatic bacteria. In culture experiment using river water in Osaka, aryl system OPEs such as triphenyl phosphate (TPP) and tricresyl phosphate (TCP) are more easily degraded than alkyl system OPEs, and OPEs including Cl are hardly degraded. Properties of isolated TBP degradation bacteria and enzymes, and TCP degradation bacteria isolated from Mukogawa river water are examined. OPEs are toxic to fishes equivalently to or more than organophosphoric system pesticides. However, the cause of their toxicity can`t be interpreted only by cholinesterase activity hindrance of nervous system. Absorption, accumulation, metabolism and degradation of OPEs are dependent on fishes and kinds of OPEs. Although the toxicity evaluation using experimental animals is important, the evaluation using cultured bacteria is recognizing once again from various viewpoints. Direct toxicity of OPEs to fishes or aquatic organisms is yet unidentified, however, the influence of OPEs on human beings is rather important. 39 refs., 10 figs., 2 tabs.

    This paper describes the results of the experiment in which crystallization of protein of reactive center purified from the photosynthetic film of thermophilic purple sulfur photosynthetic bacterium Chromatium tepidum whose hyrogen donor in photosynthesis is H2S instead of H2O was attempted. Crystallization was carried out by the vapor diffusion method and particularly by using ethylene glycol as precipitator at 4[degree]C after various investigations on the conditions of crystallization. By X-ray diffraction, this crystal was found to belong to the rhombic system, and it was estimated that the lattice constants, a, b, c equal to 140[angstrom], 190[angstrom] and 80[angstrom] respectively. This bacterium is a thermophilic bacterium having the optimum growth temperature of 48-50 [degree]C and utilizes CO2 or H2CO3 as corbon source, ammonium, urea etc. as nitrogen source and thiosulfate as sulfur source. Moreover, another purpose of this investigation was to determine the thermophilic location by elucidating its configuration (although, as a result, the analysis of configuration had no sufficient resolution). It was confirmed that the enzyme system of photosynthetic film and its cytoplasm obtained by ultrasonic spallation of this cell have CO2 fixing activity utilizing light energy. 23 refs., 14 figs., 3 tabs.

    Through an arrangement of published data about American air lines during 1985 through 1987, the overall expense vs. transportation fee (expense vs. effect) was studied as a main viewpoint. As a result, the fuel oil cost, even in case of wide fuselage plane, high in transportation efficiency, was high in ratio, 32 to 52% (3 to 5 times as high as that 12 to 14 years ago), and fluctuated connectedly with the oil price. While the jet fuel price fluctuated connectedly with the oil price per equal volume with 1.3 to 1.4 of price ratio. Further, the flight range ratio was recorded to be approx. 0.06 to 0.24 km/kg. While the transportation efficiency was lower than approx. 5000kg*km/kg with a wide range of overall expense, approx. 9 to 87 cents per compensative transportation ton*km. Because even a sudden decrease in transportation quantity did not decrease the overall expense, it was known to be important in management to secure the transportation quantity. 30 refs., 15 figs., 1 tab.

    Biodegradation characteristics of cyanobacteria, Phormidium tenue and its metabolites, 2-methylisoborneol (MIB) by protozoan microflagellate, Monas guttula, and the effect of temperature on them were examined in batch culture experiment. The flagellate was found to predate on P. tenue favorably as a food source within a wide temperature range from 10degC to 30degC. Specific growth rate ({mu}) and generation time (t{sub d}) of the flagellate were 4.6 day{sup -1} and 3.5 h{sup -1}, respectively at 20degC and 30degC, whereas in the case of 10degC the lag values of {mu} and t{sub d} were obtained by 1.9 fold in comparison with the removal ratio of 61% at the first cultivation day and that of 99% at the 2nd day at 30degC, while at 20degC the removal was only about 30% in the first day, but P. tenue could be perfectly reduced at the 2nd day. Although the reduction rate of the P. tenue was slow at the lower temperature of 10degC, the removal reached 98% in the 7th day. Removal rate of P. tenue by the flagellate increased with the increase in temperature and reached the maximal value with 4.0 h{sup -1} at 30degC. The flagellate could contribute to the degradation of MIB, although the degradation was lower than that of P. tenue. It was found that the microflagellate could favorably predate on P. tenue and degrade its metabolite, MIB emitting musty odor in a wide range of temperature. 27 refs., 8 figs., 3 tabs.

    To study the utilization of the photochemical sterilization of thermoduric bacterial spores B. stearothermophilus with photocatalysis of TiO2 particles, light irradiation experiments are conducted under various operational conditions. TiO2 particles and dissolved oxygen resulting from aeration must coexist to accelerate the rate of spore sterilization under light irradiation of a high pressure mercury lamp. The sterilization rate increases with larger average light intensity in the reactor, and it is estimated that the dissolved oxygen contributes to the formation of oxidative radicals which become the attacking species. The maximal rate of spore sterilization is obtained under the condition of TiO2 concentration of 5[times]10[sup -2]kg[center dot]m[sup -3]. By combining a second-order rate equation, wherein the spores' death caused by the oxidative radicals formed by TiO2 photocatalysis is taken into consideration, and single-hit multitarget model, wherein the target damaged by the oxidizer in the spores is assumed, the sterilization velocity can be described well, and the effect of light intensity and the obtained rate parameters are correlated well. 13 refs., 7 figs., 3 tabs.

    The Nishiyama volcano of the Hachijo island is a stratovolcano whose volcanic activity started approximately 10,000 years ago. Among the lateral volcanos surrounding the cone-shaped mountain, there is a Kandoyama tuff cone formed by a phreatomagmatic eruption at the southeastern base of the Nishiyama volcano. It is known that Kandoyama`s latest eruption is not older than 4,000 years. In this report, the stratigraphy of eruptive deposits and the types of eruptions involving Nishiyama after Kandoyama formation are clarified. Also, the history of Nishiyama` eruption is discussed, for which a study is made about the stratigraphic relationship between its eruption and the results of {sup 14}C dating or the eruption remainders, corresponding terrestrial episodes recorded in ancient literature usable for eruption dating, etc. The conclusion is summarized below. The eruptive deposits are to be supposedly dated at a period after the completion of caldera aggradation. At the southeastern base of Nishiyama, the eruption of 1605 is to immediately follow the eruption of approximately 1,100 years ago, and no eruption so active as to cause the outflow of lava is noticed therebetween. It is inferred that the Nishiyama volcano erupts once in a period of 300-700 years. 44 refs., 11 figs., 2 tabs.

    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.

    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.

    This paper describes attempts of establishing an oil recovery technology utilizing microorganisms and of aiming at improving the practicability of that technology. Fiscal 1994 has investigated effects of inorganic salts existing in reservoir beds and NaCl concentrations on proliferation of microorganisms and production of metabolites. The investigation was intended to discuss applicability of microorganisms to environments that are brought closer to actual field conditions. Furthermore, a core sweeping test using sandstone was carried out on the fiscal 1992 separated bacteria, the 4118 bacteria, that has high surfactant production capability. In addition, a sand pack was used to perform a flooding experiment under conditions of 50{degree}C and 50 KSC to evaluate functionality of microorganisms when environments in the reservoir bed are simulated with respect to pressures and temperatures. An oil recovering experiment was carried out using a sandstone with a diameter of 1.5 inches, a length of 1.0 foot and permeability of 600 md, and using Bacillus subtilis 4118 bacteria which attained the lowest interfacial tension among the bacteria examined. A recovery rate of 4.4% Sor was derived in the experiment. A recovery rate of 29.0% Sor at maximum was obtained when Bacillus licheniformis 18-2-a bacteria was supplied into a sand pack filled with silica sand. 20 figs., 7 tabs.

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

    Acid fog research was behind in comparison with acid rain research. In case of acid fog, it is because the place generating sufficiently thick fog to collect is limited, the generating place is mountainous, its survey needs a lot of works, its collector is not convenient like in acid rain, or its sampling is difficult on its automation. Since the 1980s, an extensive survey on acid fog had been carried out centering the west coast of California, USA, and low pH fog (minimum pH 2.2) was observed. In the course of these researches, string type active fogwater collectors became a major sampling method, and the simulation of acidification of fog droplet in the atmosphere was extensively conducted. In Japan, already in the 1960s, field surveys on acid fog were conducted, in 1984 acid fog survey started on Mt. Akagi under a viewpoint of ecological impact, and there was a report that low pH fog (pH 3 to 4) continued more than 10 hours. It was pointed out that there were plant damage by acid fog in several locations, especially the tree mortality mechanism in Tomakomai was clarified. 50 refs., 10 figs., 6 tabs.

    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.

    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)

    This paper reports the result obtained during fiscal 1994 on research on research on optimization of bandgap in thin film compound solar cells. In research on Cu(InGa)Se2 thin film solar cells by using a gas phase selenide making process, discussions were given on optimizing the following three processes: a process to raise temperature of a precursor film formed at a substrate temperature of about 150{degree}C, a selenide making process to perform annealing at about 500{degree}C, and a temperature reducing process. Good characteristics were obtained when selenium amount in the precursor is about 50%. In a bandgap control viewpoint, it was found that the conversion efficiency decreases rapidly when Ga composition is higher than 50%. A conversion efficiency of 14.9% was obtained to date at the Ga/(In+Ga) ratio of 0.4. In research on Cu(InGa)Se2 thin film solar cells by using a simultaneous deposition method, a conversion efficiency of 13.5% was obtained at a bandgap width of about 1.3 eV during research on manufacturing ZnO/CdS/Cu(InGa)Se2 thin film solar cells by using the simultaneous deposition method.

    Described herein are the results of the FY1994 research program for research on advanced solar components as part of research and development of solar thermal energy. The catalyst for liquid-film reactions is prepared, and the flask tests are conducted as the preliminary experiments for development of the reactor in which 2-propanol is fallen in liquid film over the catalyst dispersed to accelerate its decomposition. It is decomposable when fallen in liquid film even in the presence of 35% of acetone. The catalyst of ruthenium carried by activated coal is used to produce 2-propanol under an exothermic condition from acetone and hydrogen. Diisopropyl ether and 4-methyl-2-pentanone are produced as by-products, when the reactor tube is kept at 140 to 200{degree}C at the external wall, diminishing as temperature is increased. There is a temperature differential of 20 to 30{degree}C in the reactor tube between the center axis and external wall. 3 figs.

    This paper reports the result obtained during fiscal 1994 on research on a technology of low temperature deposition of polycrystalline thin films for solar cells. This research used ITO coated glass substrates, on which CdS was accumulated to a thickness of about 100 nm by using the CBD process, and over this deposition a CuInSe2 film was formed at 300{degree}C by using the ion cluster beam (ICB) process. The manufactured solar cells with a glass/ITO/CdS/CuInSe2/Au structure had an efficiency of 2%. In manufacturing a CuGaSe2 thin film by using the ICB process, effects of acceleration voltage relative to cluster beams and ionization current were investigated. It was found that the film morphology, the result of analysis by using X-ray diffraction, and the electric conductivity are sensitive to the ionization current. From these findings, an optimum film forming condition was derived. A CuGaSe2 thin film was manufactured by using the ICB process over a Cds thin film deposited by using the CDB process. Both of the surface morphology and X-ray diffraction patterns of the film did not show a large change, indicating a possibility of manufacturing cells with a reverse structure. Effects of heat treatment on CuInSe2 monocrystals were evaluated by using ESR and FTIR. 6 figs., 1 tab.

    This paper reports the result obtained during fiscal 1994 on research on interface of amorphous silicon for solar cells. In research on amorphous solar cells using ZnO for transparent electrically conductive films, considerations were given on a growth mechanism of a ZnO film using the MOCVD process. It was made clear that the ZnO film grows with Zn(OH)2 working as a film forming species. It was also shown that the larger the ZnO particle size is, the more the solar cell efficiency is improved. Furthermore, theoretical elucidation was made on effects of rear face of an interface on cell characteristics, and experimental discussions were given subsequently. In research on solar cells using hydrogen diluted `i` layers, delta-doped solar cells were fabricated based on basic data obtained in the previous fiscal year, and the hydrogen dilution effect was evaluated from the cell characteristics. When the hydrogen dilution ratio is increased from zero to one, the conversion efficiency has improved from 12.2% to 12.6%. In addition, experiments and discussions were given on solar cells fabricated by using SiH2Cl2. 9 figs.

    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.

    This paper reports the result obtained during fiscal 1994 on research on surface passivation of high-efficiency silicon solar cells. In research on carrier recombination on SiO2/doped silicon interface, measurements were carried out on minority carrier life with respect to p-type silicon substrates with which phosphorus with high and low concentrations are diffused uniformly on the surface and non-uniformly on the back and then oxidized. The measurements were performed for the purpose of evaluating the carrier recombination at p-n junctions. Effective life time of oxidized test samples increased longer than that of prior to the oxidization as a result of effect of surface passivation contributing remarkably. In research on reduction in carrier recombination on SiO2/Si interface by using H radical annealing, experiments were conducted by using a method that uses more active H-atoms. As a result, it was revealed that the reduction effect is recognized at as low temperature as 200{degree}C, and photo-bias effect is also noticeable. Other research activities included analytic research on minority carrier recombination on micro crystalline silicon/crystalline silicon interface, and experimental research on evaluation of minority carrier life of poly-crystalline silicon wafers. 6 figs.

    In order to type the sausage-shaped bacteria forming A-type sulfur-turf, cell length distributions and physics-chemical conditions of hot spring waters were investigated on twelve samples collected from all over Japan. The frequency distributions of the cell length of eight samples were bimodal, while the other four samples were unimodal. In seven samples with bimodal distributions, two types (large and small) of the sausage-shaped bacteria could be differentiated. The cell length of the large-type was between 10.1 and 31.9{mu}m, while that of the small-type ranged 2.2 to 6.6{mu}m. The pH of seven hot spring waters were between 6 and 8, and the two types (large and small) formed together sulfur-turf. In contrast, pH of the three hot springs were over 8, and the two types of the sausage-shaped bacteria could not be detected in the sulfur-turf. Therefore, it is reasonable to set a third type of the sausage-shaped bacteria which prefers high-pH (over 8) and low calcium condition. The cell lengths of the third type were in the range of 5.5 to 8.6{mu}m, which correspond to the sausage-shaped bacteria of medium size. 20 refs., 5 figs., 2 tabs.

    Fermentation characteristics are investigated for the conversion of glycolate, acetate, formate, and malonate obtained by the oxidation of low-rank coals to poly ({beta}-hydrox butyrate) (PHB) using A. eutrophus cells. Based on the cultivation experiments using one of the organic acids as a sole carbon source, it is found that acetate is the most effectively converted to PHB. When mixed organic acids are used, formate is preferentially consumed, followed by acetate, and finally glycolate. Although malate can not be utilized, it is implied that it might change the pathway flux distributions based on the metabolic flux analysis. Namely, it shows competitive inhibition to succinate dehydrogenase so that its addition during fermentation results in flux reduction from succinate to maleic acid as well as glyoxylate flux and gluconeogenesis flux. It is also found that NADPH generated from isocitrate is preferentially utilized for the reaction from {alpha}-ketoglutarate to glutamate when NH{sub 3} concentration is high, while it is eventually used for the PHB production from acetoacetyl CoA as NH{sub 3} concentration decreases.

    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.

    It is recently, that is, in and after the 1980s that socio-scientific approaches began to be made to studies on `risk`. It started to be made clear that the progress of the scientific technology does not necessarily bring about good news to man, and obvious estrangement has begun to appear between scientific evaluation and social evaluation of risk. The subject of risk communication (RC) study is to tackle a proposition whether the estrangement will continue to exist as estrangement or the estrangement can be made smaller by any means. This paper explains the recent trend of the study. For example, as for how each individual thinks about risk, that is, the risk perception, a new framework is trially being constructed by introduction of the quantitative method using psychometrics. A duty of RC is to serve to bridge the gap between scientific technology and society which are controlled by values which are incompatible with each other. Therefore, RC will be more and more important. 15 refs., 1 fig., 2 tabs.

    As measures for the spots difficult in metering within a framework to integrally automate the power distribution, a remote reading system was prototypically tested and evaluated in reliability on the actual field. The system methodically selected the signal {prime}s line injection, high frequency wave signal and voltage detection, while the signal frequency, transmission rate and highest transmission output were set at approx. 3.5KHz, 7.5bps and 50dBm, respectively from the test result. The demonstration test on reliability of the system locatively selected a vicinity of high voltage consumer, high harmonic wave-generating consumer, transforming station, etc. The total ratio of success in reception was comparatively high in Kuzuno and Yamazaki areas, but low in Kamojyo and Ichinomiya areas, The badness in reception was caused by the fluctuation in noise and strongness in damping which was influenced by the condenser in the high voltage consumer. The locative relation between the parent and child stations of system, and high voltage consumer being classified into four patters, an application table of remote reading system was prepared by simulation. 14 figs., 6 tabs.

    Study of metamorphic belts and tectonics is introduced. Minerals supposedly originating in the transitional zone and the lower mantle, that is, inclusions in diamond in kimberlite, are deemed to carry information about the depth level of 670km and lower. The place of origin of peridotite, Alpe Arami of Switzerland, is again estimated at a level of 300km or deeper. In the tectonic cross section in this region, the oceanic crust is bent and folded, and such a structure enables the supposition that fragments off the transitional zone may be carried upward to the ground surface. This region is now being limelighted, with plume tectonics enjoying popularity. The split of Pangaea is related with the ascent of plume. In the eastern part of Australia, there are alkali rocks attributable to the plume that was supposedly active at the end of the Proterozoic. Zircon U-Pb dating by SHRIMP offers a new approach to the tectonics of metamorphic rocks, and is reinforcing the position of metamorphic petrology relative to the study of collision and split of continents. 64 refs., 10 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.

    The water tank test of marine structures or submarine structures uses a wave maker to generate waves. A typical flap wave maker uses the wave making flap penetrating a water surface whose bottom is fixed on a tank bottom through a hinge, and the top is connected with a rod driven by rotating servomotor for reciprocating motion of the flap. However, this driving gear using a rotating servomotor and a bowl- screw has some defects such as noise caused by bowl rotation, backlash due to wear and limited driving speed. A linear motor with less friction mechanisms was thus applied to the driving gear. The performance test result of the prototype driving gear using a linear motor showed the possibility of the linear driven wave maker. The linear driven wave maker could also achieve low noise and simple mechanism. The sufficient durability and applicability of the linear driven wave maker mechanism were confirmed through strength calculation necessary for improving the prototype wave maker. 1 ref., 5 figs., 2 tabs.

    This paper describes course of pneumatic technologies and problems in future researches. Pneumatic systems are inferior to electric and hydraulic systems in terms of efficiency. It is because electric power is converted into fluidized energy by using a compressor, and then converted to mechanical energy by using an actuator. When theses published from 1990 through 1999 are put in order, the research objects are accounted for half by control related technologies, and researches related to elements account for only one third. This paper enumerates assignments to be tackled positively in the future by utilizing compressibility of air in pneumatic systems, and features of high speed drive utilizing the stored energy instantaneously. Application of air pressure to robotics from the demand of the aging society, and pneumatic tools having intelligent functions must be subjected to new contrivances. These will serve for work assistance systems to enable aged people to perform works, and for activating industries including organic agriculture. Tools in this sense may include impact wrench, and others. Furthermore, development of fundamental studies for 'why air pressure?' is demanded strongly, including the viewpoint of LCA in the recycling type society. (NEDO)

    The Research Group on Earthquake Ground Motion in Sapporo City established in May 1996 has inaugurated collection of information on ground structures and observations of strong earthquakes in Sapporo City. The Research Group on Earthquake Ground Motion in Sapporo City has carried out geological investigations, electric logging and PS logging to date in three boring holes each with a depth of about 100 m, 200 m and 600 m. According to the result of the logging in the new Ishikari Bay port (600-m deep hole), the S-wave velocity has increased slowly as it starts from the ground surface to greater depths, but showed no noticeable velocity boundaries in this range of the depth. The Sapporo municipal office has drilled three observation wells (500-m deep) for the purpose of determining focal points of microtremors directly under the city area. Hole-bottom observation has been inaugurated since the beginning of this year. According to comparison of the results of loggings at great depths, a depth at which the S-wave velocity reaches about 700 m/s becomes greater toward the sea area. The result of calculations on amplification characteristics of the SH wave on rock beds revealed that a seismic wave of about 0.5 Hz is amplified by a little more than two times. 1 ref., 5 figs., 1 tab.

    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.

A turbofan engine with an afterburner was experimentally fabricated and various engine tests have been carried out since 1988. Although the engine size is small, the fighter engine specifications were applied to its design and the prior or simultaneous research on each component was carried out. As a result, the system integration technique by which an engine was assembled by integrating each component could be established. New materials and new manufacturing techniques such as turbine blades of single crystal, turbine disks of powder metallurgy and deep chemical milling for a duct were developed to use for the long term engine test and the prospect to commercialization could be obtained. The following techniques have been established and the results satisfying target specifications could be achieved: the three dimensional aerodynamic design of compressor and turbine, the adoption of air blast fuel atomizer to suppress the smoke generation, an afterburner of spray bar system and the mounting type FADEC (full authority digital electronic control) to control the engine with the afterburner. 4 refs., 15 figs., 4 tabs.

    The noncontact measurement method of rotating blade vibrations was developed for fans, compressors and turbines, and applied to turbofan engines and industrial gas turbines. The method required no machining of blades and rotor except sensors attached to a casing to detect blade-tips. The method allowed to measure simultaneously the vibration of all blades, by measuring elapsed times of blade-tips rotating from a measuring start point to a detecting point, and detecting the time differences between a vibration and non-vibration condition. The measuring system was composed of the detectors and subsystems for signal processing, control, calculation and display. The vibration wave forms of a few blades and the maximum vibration amplitudes of all the blades were displayed on a realtime basis in an on-line monitoring mode, and an off-line data processing mode was also available for subsequent analyses and reviews. The results of application to existing engines favorably agreed with those of strain gage measurements. 16 refs., 75 figs., 3 tabs.

    This paper explains concepts of aircraft engine afterburner, and describes history of afterburner study, and describe the result of major research items. An afterburner is located down stream of a fan, compressor, burner, and turbine in a jet engine. Its basic principle is that fuel is injected into turbine exhaust and fan air flows from an fuel injector, ignited by a spark plug using oxygen remaining in the exhaust gas flow, burned and flame-held by a flame stabilizer. The combustion gas of high temperature (1,700 to 1,800 {degree}c) thus generated is jetted out from an exhaust nozzle to increase the thrust. The prototype afterburner is featured by adoption of a mixed type fuel injection system that provides wide stable combustion range, and flame stabilizer with a scoop aimed at improving the ignition performance and combustion efficiency. A confirmation test verified smooth ignition and wide air to fuel ratio for stabilized combustion. 4 refs., 16 figs.

    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.

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.

    Aluminum, GFRP and composite of aluminum coated with carbon as structural materials for wind turbine blades were bending-tested, to improve blade bending stiffness, understand stress conditions at each position, and clarify structural dynamic strength by the bending-failure test. It is possible to estimate stress conditions at each position from the test results of displacement and strain at each load. The test results with GFRP are well explained qualitatively by the boundary theory, known as a theory for composite materials. The test gives reasonable material strength data, useful for designing wind turbines of high functions and safety. The results of the blade bending-failure test are in good agreement with the calculated structural blade strength. It is also found that GFRP is a good material of high structural strength for wind turbines. 8 refs., 6 tabs.

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

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

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

    This study is being progressed during a period from 1992 to 1999 as part of the NEDO`s clean coal technology program. This paper describes what has been discussed to date. The absorption method and the adsorption method may be used to recover CO2 as means to deal with the problem of global warming resulted from burning coals. These methods, however, have problems in economy caused from concentration of CO2 in flue gas being low. The present study is intended to raise the CO2 concentration in flue gas by using oxygen plus circulated flue gas in the place of combustion air, so that CO2 may be recovered as it is without being separated from the flue gas. Therefore, an oxygen-blown pulverized coal fired power generation plant having a cryogenic oxygen manufacturing equipment was designed to discuss the plant operability and economy, and the pulverized coal combustion technology by using a dynamic simulation. A large number of findings have been obtained already, and the study has reached a level at which grasping the whole image is now possible. 13 figs.

    In order to grasp the phenomena actually occurring in the combustion chamber for improving the combustion and for reducing the exhaust gas emission of the diesel engines, the visualization techniques are becoming to be essential and indispensable. The authors have observed the spray and combustion, when proceeding the combustion improvement by the high pressure injection, and then have performed the image processing and simulation calculation based on them. The high pressure injection devices used for the experiment are the intensifier type and accumulator type which can generate the injection pressure more than 200MPa, and both of them are the electronic controlled hydraulic drive type, and are driven separately from the engine. Since it was found that the analysis of high pressure injection by the hologram is limited in the conditions, as for the spray, the spray analysis was performed by the transmitted light attenuation method and laser sheet method. As for the combustion, the engine for observing the combustion was trially made, and then the combustion state was observed by the high speed photograph. Furthermore, the flame temperature analysis by the image processing using the combustion photograph and the analysis of flow and turbulence of the flame were carried out. 9 refs., 16 figs.

    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.

    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)

    The energy saving environment-friendly technology for low- grade difficult-to-process ores was researched focusing attention on the hydro-metallurgical process of non-ferrous metals. This research aims at development of both effective leaching system of metals, and separation/crystallization system recognizing the property difference between metal ions in solution. The leaching system allows the inexpensive molecular level control of electron transfer, mass transfer of metal ions and stabilization of leached metal ions in a solid/liquid interface. The system thus allows selective leaching of metals from various resources such as difficult- to-leach sulfide minerals to prepare concentrated solutions. The separation system can obtain high-purity solutions including each metal ion by advanced separation/concentration technology from the solutions. The crystallization technology (including electrolysis) is developed for preparing target metal materials by molecular level control of nucleation, particle growth, thin film formation and bulky metal formation processes. Overall energy consumption is reduced to 1/3 of that of the pyro-metallurgical method, aiming at zero emission. 15 refs., 14 figs., 11 tabs.

    Summarized herein are R and D results of the researches on the chemical heat storage systems, plant simulation techniques and combined systems, and international technical exchanges, for R and D of the super heat pump energy accumulation system. For the high temperature heat storage type (utilizing ammonia complexes), the initial research targets are almost attained, as a result of the designs of a chemical heat storage unit having heat storage capacity of 1,000 kWh. For the high temperature heat storage type (utilizing hydration reactions), a 25 Mcal-scale pilot partial test unit is operated, to study applicability of the practical materials and other operation-related themes. For the low temperature heat storage type (utilizing hydration reactions by solute mixing), a pilot system is operated, to attain heat recovery of 75% or more, heat storage density of 30 kcal/kg or more, and output temperature of 7 degrees C. For the low temperature heat storage type (utilizing clathrates), the evaluation tests by a pilot plant produce heat recovery of 93.2% and heat storage density of 32.0 kcal/kg.

    This paper reports the result obtained during fiscal 1994 on a demonstration research on photovoltaic power generating systems. Solar cells with an output of 750 kW, storage battery facilities with an output of 3,058 kWh, three DC-AC converters with a rating of 250 kW, and a diesel generator with an output of 300 kW having been installed up to the previous fiscal year were combined to perform comprehensive adjustments and tests such as battery charge/discharge tests and AC parallel operation tests. The battery charge/discharge tests revealed that the 10 hour rate discharge capacity meets the specifications, and the batteries are free of deterioration after a demonstration operation of about 4.5 months. Difference between the power generation record and the planned value is thought due to the following reasons: the array output data in a power line connected system come about 90% of the simulation result due to correction coefficient for the solar cell conversion efficiency; the inclined face insolation results in less by about 7% than the planned value, and the transmittable power amount less by about 14% in total; the load power amount is less by about 7% than the planned value; and the balance supplementing power factor increases by about 4%. 5 figs., 2 tabs.

    Computer chemistry was investigationally studied. The advance of theoretical chemistry is indispensable to the design of materials, and the theory and high speed computational method are expected which can simulate the real system with more accuracy. It is basic to simulate structures and physical properties of structural molecules and the aggregate, but the meso region, the intermedium region between structural molecules and the aggregate, has became regarded as important. Rough visualization models in high polymer materials and the progress of computational software/hardware of quantum chemistry/molecular dynamics such as catalyst become necessary. Seamless zooming is proposed as a concept of the software which simulates materials from micro/macro/meso viewpoints. Moreover, to make the most of computer chemistry, an integrated system is necessary which generally handles computational software, database, etc. For the development of software, indispensable is the demonstrative verification by a combination of experiments and researchers. Under a commission from NEDO, the investigational research was conducted as a leading study during fiscal 1996 and 1997 to view the course of the research. 17 refs., 37 figs., 5 tabs.

    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. Liquefaction layers found in remains are also introduced. 16 refs., 6 figs.

In the study, the most up-to-date information/knowledge and future problems were examined on brain measurement, brain modeling, making a model an element, and the brain function data processing system. As to the brain measurement, the paper took up the multielectrode simultaneous measuring method and the optical multipoint measuring method as an invasive measuring method, and the functional magnetic resonance imaging, near-infrared spectroscopy, magneto-encephalography, and electro-encephalography as a non-invasive measuring method. Relating to the brain modeling, studies were made on senses of sight and smell, the movement control and the learning. As to making a model an element, how to make the modeled function a chip on silicone for example becomes the problem. Reported were two reports on making the sense of sight an element and one report on making the parallel dispersed processing mechanism of brain an element. About the brain function data processing system, three reports were made on the present situation, matters in question, and the future development of the system in the case of catching data processing as a system taking a step ahead from making the model an element. 250 refs., 74 figs., 11 tabs.

    My efforts towards at the development of aeroengines since the end of the war are described. The J3-7 engine propelled the T1 trainer plane, and was installed as booster aboard the P2J antisubmarine patrol aircraft. It was the first jet engine that Japan produced after the end of the war, and had been in use until quite recently. I took part in the construction of a prototype of the JR100 series designed to serve as VTOL (vertical take-off and landing) aircraft lift engines, and in the test thereof. As the shift from turbojet to turbofan proceeded, I participated in the development of the FJR710 engine under the guidance of National Aerospace Laboratory, and the product was installed aboard an experimental STOL (short take-off and landing) aircraft Asuka. I next joined a Defense Agency initiative for a reheat turbofan to replace the J3 aboard trainer plane, and the result was the low bypass ratio/high output F3 engine. In 1989, Ministry of International Trade and Industry decided for a large-scale project of developing an engine for a next-generation supersonic transport, and the HYPR (Super/Hypersonic Transport Propulsion System) project was started. The project was participated in by manufacturers from overseas, which were GE, P and W, RR, and SNECMA. The foreign corporations worked on an equal footing with the Japanese parties, and collaboration between the participants was smooth, with each party endeavoring in the field they were good at. The project will be concluded as scheduled in fiscal 1998. (NEDO)

    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.

    Summarized herein are R and D results of the super high performance heat pumps and elementary equipment, for R and D of the super heat pump energy accumulation system. For R and D of the super high performance compression heat pumps, the R and D efforts are directed to tests and evaluation of the pilot plant for the highly efficient type (for heating only), which produce the results of COP exceeding the target of 8; to tests of the anti-corrosion measures for the aluminum heat exchangers for the highly efficient type (for cooling and heating), by which the effective inhibitors are selected. The hybrid systems of the super high performance compression heat pumps and chemical heat storage are also studied in detail. The R and D efforts are directed to construction and operation of the hybrid heat pump system to collect underground heat for the high temperature type (utilizing low temperature heat source), which produce the results of confirming possibility of efficient heat collection for extended periods; and to improvement, construction on a trial basis and operation of the high-speed reciprocating compressors and steam superchargers for the high temperature type (utilizing high temperature heat source). For R and D of the elementary equipment, tests and evaluation are conducted for the EHD heat exchangers which use R123 as the new working fluid. (NEDO)

    Discussions were given on airbags equipped in passenger cars as to methods of evaluating their deployment injuries. Airbag deployment injuries occur in occupants being out of position. In a driver`s seat, an injury may occur when an air bag deploys under a condition that a driver with relatively short body height gets closer to a steering wheel to maintain the driving posture. In a front passenger seat, if a child is not held in a restraint equipment, the child may be blown off into the vicinity of the airbag, whose deployment can cause an injury. According to the result of a test performed on a driver being out of position, the test method using a hybrid 3 dummy specified in the present ISO procedure may not necessarily be said to produce an evaluation on the worst case. In order to solve the problem, an ATD dummy which can measure bend in each rib independently would be used, or the hybrid 3 dummy must be measured in the worst set position. 4 refs., 8 figs.

    Validation researches have begun about the interrelationship between systems and human beings using a virtual-reality plant environment. This article introduces some recent studies about the human interface in an operation control system in a virtual-reality environment. The evaluation of a system from the viewpoint of ease of use is called a usability test, to which a psychological protocol analysis is applied for finding out problematic points by carefully observing the operator actually operating the system. For instance, in a boiler plant simulator constructed for DCS training, the operator is given some tasks, such as the prediction as to how a certain event will develop, probing of the cause of anomalies, and execution of related operations. Video cameras are installed at various spots for the minute observation of facial expressions and behavior of the operator, and the operator`s recognition, thought, behavior, and utterances, expressed by the operator facially or verbally, are recorded and analyzed, and the results are utilized for system improvement and operator training. 3 refs., 2 figs.

    This paper summarizes study trends mainly in CO2 fixing processes. Underground CO2 storage is a most promising method because it can fix a huge amount of CO2 and has low effects on ecological systems. Storing CO2 in ocean includes such methods as storing it in deep oceans; storing it in deep ocean beds; dissolving it into sea water; neutralizing it with calcium carbonates; and precipitating it as dry ice. Japan, disposing CO2 in these ways, may create international problems. Separation of CO2 may use a chemical absorption process as a superior method. Other processes discussed include a physical adsorption method and a membrane separation method. A useful method for CO2 fixation using marine organisms is fixation using coral reefs. This process will require an overall study including circulation of phosphorus and nitrogen. Marine organisms may include planktons and algae. CO2 fixation using land plants may be able to fix one trillion and 8 hundred billion tons of CO2 as converted to carbon. This process would require forest protection, prevention of desertification, and tree planting. Discussions are being given also on improving power generation cycles, recovering CO2 from automotive exhausts, and backfilling carbons into ground by means of photosynthesis. 23 refs., 7 figs., 1 tab.

This paper summarizes the achievements in fiscal 2000. In the study of increasing densities of superconductors and field windings, strands were fabricated, in which aging heat treatment conditions, number of aging, and processing degrees between each aging were varied, to increase the critical current of Nb-Ti strand, wherein as high critical current as corresponding to about 90% of the target was obtained. Possibility of increasing the critical current with the final processing degree in the range of 4 to 5 was verified from the relationship between the final processing degree and the critical current. In the study of increasing capacities of superconductors and field windings, findings were acquired on enhancement of conductor stability and reduction in AC loss, with regard to superconductor strands well balanced in the two elements. Prospects were obtained in achieving the AC loss of 200 kW/m{sup 3} in the targeted superconductor. The residual resistance ratio was found to be 200, showing sufficiently high value, and sufficient function was verified in the stabilized copper.

    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.

    Researches were conducted with a view to organizing projects for developing intelligent fibers, equipped with environmental friendliness and amenity without being deprived of their original properties as structural and clothing materials, the ultimate goal of the effort being the creation of harbingers of next-generation fibers which would contribute to the advance of industries related to environments, medicine and welfare, and information. What were learned from fiscal 1998 researches are mentioned below. The strength that the general-purpose fibers currently in use exhibit is so small as to be but several percent of what is theoretically predicted for them. Demand will increase a great deal if the actual strength is doubled, for which new technologies have to be developed including those involving super-fiber texture control. For providing the fiber with such functions as environment-friendliness, amenity, etc., it is necessary to develop phasal structure control technologies with regard to fiber morphology, surface texture, etc. For success in practical application in the future of such super-fiber materials, each specimen needs to be manufactured in the order of kilogram by way of trial. Moreover, fiber evaluation techniques have to be developed in the three domains of software, hardware, and interface. (NEDO)

    For the promotion of research exchanges on global environmental preservation with developing countries, Ms. Malee Santikunaporn, lecturer of Faculty of Engineering, Thammasat University, Bankok, Thailand was invited. Desulfurization/denitrification facilities, which are being widely spread in developed countries, have marked effects, but high prices are an obstacle to the spread in developing countries. To make them spread in developing countries, it is needed to develop the technology which is low in price and meets the actual state in developing countries. As a technology with high viability, a system to simultaneously remove SOx and NOx was cited in which Cu is used as catalyst and adsorbent and into which the catalyst regeneration process is integrated. Considering it, technical exchanges on Cu-SiO{sub 2} catalyst as the basic theme were made during September 26 - December 23, 1999. Through visits on and exchanges with Tokyo Institute of Technology, ICEET, University of Kyoto, etc., understanding was deepened about how each country is tackling environmental problems. The theme 'Oxidative sorption of SO2 by Cu-SiO{sub 2} catalyst: characteristics of catalyst' could deepen knowledge/information of the developmental research as a system for simultaneous removal of SOx/NOx. The data obtained indicated great practicality of Cu-SiO{sub 2}. (NEDO)

    Research, development and evaluation were performed with an objective of establishing the basic technology related to three-dimensional circuit elements that integrate functions at ultra-high density. For the basic technology of lamination, the SOI technology suitable for the three-dimensional circuit elements was developed, and it has become possible to manufacture high-quality multi-layered crystalline structure by means of annealing that uses laser and electron beam. In addition, a lateral epitaxial technology for solid phase was developed, and the base to be applied to the three-dimensional circuit elements was established. Furthermore, the technology to put thin film circuits together would be useful for high-density integration in the future. The three-dimensional circuit makes parallel processing in each segment possible, whereas a possibility was shown that the processing can be performed at much higher speed than before. Actually a prototype three-dimensional circuit equipped with functions for parallel processing and judgment processing was fabricated. The image pre-processing which has been impossible on the real time basis in the conventional two-dimensional integrated circuit was realized in a speed as fast as milli-second order.

Described herein are the FY 1996 results. For creation of living soft tissues, N-ePTFE and Gf are found to be good base materials for cell growth in the serum-free culture, and may be applicable to bio-reactors. Sugar-bound high-molecular-weight compounds and artificial hyaloid body are created. For hard tissue materials, e.g., artificial articulation, the macrophage is activated by englobing worn debris of polyethylene, to activate the broken bone cells that absorb the bone, causing the artificial articulation to become loose. For researches on molecular motor mechanisms, it is considered that myosin changes the head morphology to give a driving force to the muscle, and this concept is studied in detail. The photosynthesizing protein is a molecule related to light and electricity, and is useful as the material to apply the living functions to industrial technologies.

    To further enhance energy efficiency by improving on the gas turbine system, it is necessary, first of all, to develop superhigh-temperature materials to allow the system to operate at higher temperatures. Described in this report are studies on the application of MGC (melt-growth composite) materials which retain strength and plastic deformation capability even at high temperatures. Various compositions are explored for improvement on fracture toughness and thermal shock resistance. The Al{sub 2}O{sub 3}/YAG system is investigated for the study of relations between microstructural control and fracture toughness. Literature on the development of nanocomposites is surveyed, and a preliminary experiment is discussed for improvement on purity by zone melting crystallization. In a study for an advanced manufacture of larger crystals, technologies of crystal growth condition setting and optimization, quality stabilization, productivity improvement, and crystal size enlargement are taken up. Casting and machining technologies are studied to enable crystals to assume complicated shapes. For the purpose of elucidating the mechanism of the occurrence of properties proper to high temperatures, a study is made on the evaluation of mechanical and physical properties and on the mechanism and control of crystal growth. Also studied are systems (gas turbine cycle, combustor, etc.) to which MGC materials may be applied. (NEDO)

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

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

    The first term has performed research and development placing emphasis on that 'the basic study on membrane separation is to be performed systematically to elucidate governing factors in membrane separation'. With respect to water/ethanol separation by using the penetration gasifying method, it was indicated that excellent separation performance can be exhibited by using natural polymers having sugar chain skeleton as a raw material, and by controlling the membrane structure by means of membrane manufacturing methods. For enhancement of performance in water selective permeation type separation membrane, it was shown experimentally that it is important to select a membrane suitable for the object of separation and a separation method that uses the selected membrane. Regarding the water/ethanol separation, it was shown theoretically that the penetration gasifying method can save more energy than the conventional distillation method, where the development target was presented. It was recognized that impregnation type liquid membrane using crown ether can separate amino acid optical isomers. High separation performance was obtained in carbon monoxide/nitrogen separation by using fluid carrier that uses cuprous iodine/1-methyl imidazole. (NEDO)

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

    A proposal was given on a new processing process to use Ni-group super alloy, and elucidation was given on super plasticity phenomenon by using non-destructive tests. The Ni-group super heat-resistant alloy Mod. IN-100 subjected to different preforms by means of extrusion was given a super plasticity test at 1,050 degrees C to derive total elongation and 'm' value. As a result, it was disclosed that a material annealed for one hour at 1,070 degrees C after extrusion of 70% at 1,100 degrees C possesses the maximum 'm' value in the vicinity of 2.0 times 10{sup -2}s{sup -1}. The largest key to the new processing method is to improve the nature of the material, in which the plasticity manifestation velocity is accelerated by ten times to the order of 10{sup -2}s{sup -1} as described above. In addition, forging of IN-100 was made possible by using the ordinary forging equipment with the use of two-fold measures. The measures consist of maintaining temperature of IN-100 during casting by heating the die material to about 600 degrees C, rather than keeping it at a constant temperature, and then packing IN-100 in S35C steel material to accommodate the temperature decrease during casting inside the S35C pack. Thus, a processing method was made practical, eliminating need of the forging process to compress and solidify powder itself, that is the extrusion process. (NEDO)

    This R and D project is aimed at development of highly functional materials for aerospace devices, bringing into focus research and development of resin-based composite materials (FRPs), metal-based composite materials (FRMs), and evaluation of their properties and their design techniques. The basic target properties are heat resistance temperature of 250 degrees C or higher and tensile strength of 240 kg/mm{sup 2} or more for the FRPs, and heat resistance temperature of 450 degrees C or higher and tensile strength of 150 kgf/mm{sup 2} or more for the FRMs. This R and D program has been implemented for 8 years for development of raw materials, molding/processing techniques, quality evaluation and designs through information exchange and discussions of the experts in each area under integrated, close cooperation from raw materials to molding/processing. Most of the data indicate that the target properties and objects are satisfied or exceeded. It is therefore concluded that this project for the composite materials, extending for 8 years in 3 phases, has sufficiently achieved the initial objects. The unique techniques are incorporated in the raw materials, molding/processing processes, quality evaluation and designs. These efforts have produced the FRPs and FRMs of the world highest qualities. (NEDO)

    Product evaluation has been investigated from a viewpoint of compatibility with human life by considering human being as the subject of life. This report describes the investigation results. Product evaluation is defined as evaluating products on a consumer-oriented viewpoint and informing consumers of the evaluation results. According to a questionnaire survey with regard to daily living products, products in the low degree of satisfaction in their usage were electric tooth brush, video camera, electric rice jar, vacuum cleaner, and electric iron. Contents of dissatisfaction with these products were classified by aspect, i.e., human aspect regarding human body/recognition, life aspect regarding functions of products and how to use them, and sensitivity aspect such as appearance of products. Thus, points at issue were clarified. As regards the human aspect, incompatibility between the size/form of products and human body/posture, and recognition psychological incompatibility such as difficulty in understanding function or operation of products were pointed out. Establishment of a method for measuring and evaluating the human`s body functions and the compatibility with products, and necessity of the acquisition of human`s body characteristic data and the consolidation positions are also described. 4 refs., 42 figs., 30 tabs.

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

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

    Described herein are the results of the FY1994 research program for structural defects of silicon-based amorphous materials for solar cells. The study on light generation defects of the a-Si:H system and rejuvenation process by annealing establishes the effects of light irradiation time on changed neutral dangling bond density as a result of light irradiation at varying temperature of 77K, room temperature and 393K. The study on annealing to rejuvenate light generation defects of various types of a-Si-H systems establishes the activation energy distribution with respect to annealing to remove light-induced defects, showing that hydrogen affects the distribution of light-induced defects. The study on decaying process of light-induced ESR for undoped and N-doped a-Si:H systems observes the decaying process of light-induced ESR, after light is cut off, extending for a period of several seconds to several hours at 77K for the a-Si-H systems containing N in a range from 0 to 12at%. The other results presented are space distribution of neutral defects of light-irradiated a-Si-H systems, and rejuvenation process of light-induced spin for the a-Si(1-x)N(x):H composition. 6 figs.

    The research and development in the first term has searched widely different kinds of raw materials, elucidated electricity conduction mechanism, discussed processing technologies and evaluation methods. It also included molecule designing to develop new raw materials. A method for growing good single crystals of charge migrating complexes was developed, and (BEDT-TTF){sub 2}I{sub 3} crystals were found to manifest superconductivity at 8K under pressure of 1.3 kbar. In addition, elucidation was made on conduction characteristics of (TMTSF){sub 2}ClO{sub 4} being an induction superconductor, and on its superconduction mechanism. Polyacetylene films oriented at a high level by epitaxial polymerization were synthesized, the carrier hopping mechanism of polyacetylene was proposed, and the direction of increasing the conductivity was shown. It was discovered that cyanoacetylene is thermally polymerized at a relatively low temperature, turning into polymer with good orientation and easily into graphite. Polymeric intermediates soluble to polyparaphenylene vinylene (PPV) were synthesized, whereas these intermediates were found to have shaping and stretching properties, and conductivity of 2.8 times 10{sup 3}s/cm was obtained in PPV doped after the stretching.

On junction formation, the solar cell fabricated by spray coating showed output characteristics equivalent to that by rotary coating or phase diffusion, and inexpensive coating liquid, 1/40 of commercially available liquid in price, showed a sufficient result, however, the conversion efficiency of P{sup +}/N elements was insufficient. Schottky barrier polycrystal Si thin film was suitable for large-area elements without any property degradation. Small grain boundary density of polycrystal layers was also necessary. Temperature characteristics of collector element structure with a comb electrode were calculated theoretically. Change in diffusion length of minority carriers due to temperature well agreed between measured and calculated ones. Optimization calculation was also carried out. The size, curve, weight and transmissivity of plastic and glass materials for solar cell packaging were evaluated by continuous outdoor exposure tests. Fluorinated ethylene-propylene, methyl methacrylate and polycarbonate plates and glass were the most promising materials because of less deformation. (NEDO)

    Trends of research on carbon based composite materials were surveyed through studying various reports and technical literature and evaluation of the project named above was conducted through holding interviews with researchers. In the survey of research trends for which technical literature perusal was the main tool, it was found that in most technical articles the important task was the enhancement of oxidation resistance, that SiC coating was in use for this purpose, that the technology would meet its limit at 1,600-1,700 degrees C, and that it would turn useless at temperatures beyond 1,800 degrees C. For the evaluation of the project, interviews were held with nine researchers not taking part in the project. The researchers favored the project as far as the popularity of the project and the main implementing body and system were concerned, but they negatively evaluated the project's goal of using such materials at 2,000 degrees C in the atmosphere. This research report comprises four chapters which cover (1) trends of research on C/C (carbon/carbon) composites, (2) a summarized research report on C/C composites, (3) survey of patents associated with C/C composites, and (4) opinions expressed toward the project and the results of evaluation conducted on the same.

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

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

The conditions of optimum utilization of the system are studied for eventual commercialization and spread of these systems, including analysis of load types for specific purposes, prediction of operation management, economics of CGT, environmental impacts, and possibility of diversification of the fuel. The CGT cost analysis results indicate that a CGT system is well viable when the incremental initial cost of the power generator is kept below 70,000 yen/kW over the conventional system. The system can be doubled in scale at the largest. It can be further scaled up, when hybrid members with metallic materials are used. CGT is a basic technique for (system energy). In other words, the 21st. century will be the age of (system energy), i.e., (gas turbine). (NEDO)

    This report summarizes the fiscal 1974 research result on R and D of new type solar cells, which includes researches on (1) solar cell structure, (2) packaging, and (3) improvement of a conversion efficiency. In the 1st research, theoretical study was made on the relation between a solar cell efficiency and various design factors to obtain basic data for ordinary cell structure and vertical junction type cell structure. As impurity source, a thermal diffusion method using doped oxide by CVD was compared with that using boron nitride, resulting in no difference in solar cell characteristics between both methods. The measurement results on contact resistances of Al, Fe and Ni with electrodes prepared by electron beam deposition showed that these materials are applicable to Si more than 10{sup 18}/cm{sup 3} in impurity density as electrode materials. In the 2nd research, exposure tests were made on some kinds of specimens, resulting in no troubles. Study was made on production costs and structures suitable for automatic production of 4 kinds of packages with different basic structures. In the 3rd research, the prototype solar cell was prepared to use under solar radiation within 20SUNS. (NEDO)

    Described herein are results of evaluation of the developed excavators remotely controlled for highly deep submarine oil fields. The excavator system was designed to work at the target water depth of 200 to 250 m and excavation depth of 8,000 to 9,000 m, though not quite satisfactorily. There were several practical problems to be solved, e.g., those found in accuracy of reentry in the excavated section, cables connecting the driving equipment to the excavated section, and entangled hoses. The works were divided and system was configured in an attempt to secure all-weather type serviceability and to improve economic viability. The other major works included attempts to improve equipment functions and reduce manpower cost. Nevertheless, however, the construction cost was considered to be higher than expected, and no firm prospect was obtained whether the new excavator system was economically competitive with the conventional rig. The factors that pushed up the construction cost were various facilities needed by the new system with the separated excavation and driving sections, e.g., those facilities for helping the system land on the sea bottoms, material supply/storage facilities, and automated/unmanned facilities. The system failure and other items related to reliability are no clearly understood, making it difficult to compare it with the conventional rig in service factor.

    Element technology research was performed on 'rotation control' aimed at practical application of a 10-MW class high-temperature superconducting flywheel power storage system. As part of the research, researches were carried out on small-size and middle-size models, low-loss control type magnetic bearing, and large-size models. For the small-size model, as a result of performing performance tests on the protective bearing by using a testing machine, it was revealed that the model is free of problems in the test for up to 5000 rpm. For the middle-size model, fabrication and installation were completed on a middle-size rotation control testing equipment having CFRP-made flywheel with a diameter of 1 m. In the control type bearing, as a result of adopting a homo-polar type magnetic pole, the rotation loss was reduced to about 1/5 of that of a hetero-polar type. The amount is about 75 W (12000 rpm) when the bias current is 1.5 A. Concept design was implemented on a 2-MWh flywheel bearing system supported with a high-temperature superconducting magnetic bearing as a full-size flywheel. The CFRP-made flywheel has a diameter of 4 m, and a circumferential velocity of 1200 m. (NEDO)

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

    Research, development and evaluation were performed with an objective of establishing the basic technology related to light-reactive materials that control the structures and status of aggregation of molecules by using actions of light, and can be used for ultra-high density recording, high resolution indication and light switches. In elucidating the mechanism of light deterioration reaction of photochromic molecules, it was disclosed that 6-nitrospirobenzopyran has the light deterioration caused from the excitation triplet state. This disclosure presents a possibility of preventing the light deterioration. New derivatives that show photochromism were synthesized, and thin films were produced by using the LB process. This indicates a possibility of producing the photochromic materials as the high multiplex recording material. With regard to PHB materials, an evaluation technology having spectrum resolution of the world's highest level was established and measurements were performed. Hole formation was verified for the first time in the world at the temperature higher than the liquid nitrogen temperature by using a PHB material of ionic porphin/polyvinyl alcohol systems.

    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.

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

    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 basic technology was conducted on a superstructure lattice element. With an objective of developing a molecular beam epitaxy (MBE) method, which is the basic technology for preparing the superstructure lattice element, the development of silicon clean surface preparing technology was performed, as were the development of molecular beam source, the development of two-dimensional analytical program for designing the element, etc. For the clean surface, comparison was made on various methods, developing a method capable of making a clean surface usable for the MBE fully by a low temperature process that had been non-existent. This was a low temperature thermal etching method which jointly uses a chemical process and a low warmth process. In the molecular beam source, it was found that a large size was necessary for the purpose of improving the purity of the molecular beam and also the characteristics of an epitaxial film, so that a large molecular beam source was developed. A conventional two-dimensional analytical program was improved and developed for the purpose of designing the superstructure lattice element and clarifying the characteristics. By applying the result to the analysis of the motion of the element with impurities doped in the manner of a superstructure lattice, the effectiveness was confirmed of this analytical method. (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.

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

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

    This paper describes the contents of studies carried out for four years on a fluorescent lamp type vegetation plant. The equipment consists of a chiller unit with 5 HP, a motive power board of three-phase 200 V/feeder with an annual power capacity of 20 kW at maximum, and a micro-computer to control the culture environmental conditions. Discussions were given on the equipment performance, profitability, production capacity for salads and lettuces, and related data. Although the system has some disadvantage in the economy, it provided effective results on the know-hows in culturing high-class vegetables and fruits under season-free and chemical-free conditions. Since the natural light is also required, the professional knowledges and know-hows in this area were incorporated in the development. Fluorescent lamps emitting three primary colors of red, green and blue were devised and used. Because insufficient light intensity would raise the temperature only up to 42{degree}C when the ambient temperature is 25{degree}C, a proximity illumination system was adopted, which provided 45KIx high light intensity as well as the working spectra over an wide area. Tomato cultivation has also become possible, which is an epoch-making success. The system yielded better than hydroponic cultivation in solar greenhouse of the same size. 11 refs., 16 figs., 2 tabs.

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

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

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

    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. The investigation will restart in the next fiscal year. 4 refs., 38 figs., 30 tabs.

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

    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.

    Traffic jams are investigated numerically and analystically in the optimal velocity model on a single-line highway. The condition is found whether or not traffic jams occur when a car stops instantly. It is shown that traffic soliton appears at the threshold of occurrence of traffic jams. The Korteweg-de Vries (KdV) equation is derived from the optimal velocity model by the use of the nonlinear analysis. It is found that the traffic soliton appears only near the neutral stability point. The soliton obtained from the nonlinear analysis is consistent with that of the numerical simulation. (author)

    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.

    The purpose of this project is to develop new 2-dimensional ultrafast MRI (Magnetic Resonance Imaging) methods for the Image Guided Cancer Therapy (IGT) and the non-invasive clinical diagnosis. We have developed two MRI methods. They can reconstruct a two dimensional image by only a RF excitation and slow changing of gradient fields. This paper describes theoretically how to apply the RF wave and the gradient in x, y and z direction, respectively. Echo signals are acquired under multi-frequency resonance. The frequency bandwidth of the RF wave adjusts the field of view (FOV) of the imaging plane. Biological effects of the applied RF wave was evaluated by the brain microdialysis. In animal experiments, these was not significant change of neurotransmitters subject to the RF wave. From these theoretical and experimental results, these MRI methods are applicable to IGT and the clinical diagnosis for the cancer and other diseases. (NEDO)

    In order to create new functional organic thin film materials, basic data were examined under micro-gravity. Polymerization of pyrrole was affected by micro-gravity after a few minutes from the beginning of reaction. Although relatively uniform particles were obtained, the particle size was finely dependent on conditions. Electrolytic polymerization of conductive organic thin films was yet unstable in reproducibility. On orientation control and thin film formation of protein under gravity-free environment, electrodeposited films were obtained using bacteriorhodopsin film suspension by applying voltage of 6.4V for 9s after 1s from falling. The reproducibility of the number and area of molecular layers was poor. On the study on the formation process of organic thin films, creation of homogeneous films is probably possible by filtration from suspension under reduced pressure under micro-gravity for a short time. Trial linear polymer tied in a row was obtained by capillary injection of dense polymer solution. The viscous fingering phenomenon of viscoelastic bodies under micro-gravity was compared with that on the ground. 11 refs., 36 figs., 1 tab.

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

    For the turbine which is one of the principal elements of aircraft engine, progress in turbine use material development and cooling performance further heightened for the turbine are needed to grapple with the required heightening of turbine inlet temperature. In the present paper based on the turbine inlet temperature designed to be 1600[degree]C as a target, a two-dimensional model used for the turbine cooling performance test was structurally given together with the result of the above test which aimed at confirming the design calculation. As a result of cooling design for the turbine which was about 1600[degree]C in inlet temperature, the highest gas temperature was 1890 and 1470[degree]C on the stator blade and rotor blade, respectively. Both those blades were 0.66 and 0.62, respectively in cooling efficiency. To test the cooling performance, a two-dimensional cascade was tested with a doubly amplified model of cooling blade, the use of which could set its Reynolds number near that of the actual one. As compared with the actual operation, the test was made at low temperatures of 400 to 500[degree]C and low pressures of 0.02 to 0.03MPa. The test agreed with the design calculation in result. 4 refs., 8 figs.

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

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

    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.

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

    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.

    Discussions have been given on developing a seawater desalination system by solar energy distillation. The system is composed of evaporators installed on the seawater level, condensers placed on high and cool locations, and steam transport pipes to connect these two pieces of equipment. Steam is generated from seawater heated by solar heat in evaporators, and the steam is transported driven by low power consuming fans to higher locations through the steam transport pipes, where it is condensed by cool air in the condensers, and recovered as plain water. The concept is such that electric power required to operate the fans is supplied from photovoltaic panels, and all other energy is obtained from the sun. First, an experiment was performed upon noticing on methods of transporting and condensing the steam. The experiment used plain water rather than seawater. The heat source and evaporators were installed on the first floor, and the steam transporting fans on the second floor of an atrium. The thermal load was set to 1.5 times greater than average outdoor insolation amount. Increase in the distilled water recovery rate and distillation efficiency was verified by using the fans. The evaporation efficiency was found to tend to increase when the steam flow rate is increased. 3 refs., 10 figs.

    For expanding the optical diagnosis to clinical medicine, we tried to use the several optical characteristics of living tissues in addition to absorption measurements of blood. The scattering and luminescence of the tissue were examined in detail. The final goal of the research is to introduce the contrast agent active in the near-infrared region. (1) We have succeeded in obtaining the scattering and absorption coefficients separately from the time-resolved data of living tissues such as rat head and even human head. Then, based on the basic equations derived from our experiments, the quantification of the absolute absorbance was performed. (2) Using the near-infrared fluorescent dye, Rhodanine 800, we could monitor the energy state of tissues. We concluded that Rhodamine 800 is the possible candidate for energy-reporting contrast agent applicable to near-infrared spectrophatometry. (NEDO)

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

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

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

    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.

    To be ready for the computing-everywhere age to come, it is necessary to create environments in which the barrier-free utilization is ensured of various apparatuses of the daily routine, such as various bodily function substituting apparatuses capable of compensating for the degraded functions of disabled or aged individuals. Under the circumstances, a system for building man-machine interfaces in the home or the like is required, and fundamental technologies of architecture and information infrastructure have to be established on which the development of technologies for the field involved will proceed. 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.

    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)

    Studies are conducted on three subjects, which are the development of 1) high-temperature energy materials technology, 2) ultrasophisticated materials technology, and 3) high-performance active materials technology. Under subject 1), high-strength porous materials are to be developed, which are resistant to heat and corrosion, tolerant of damage and deformation, and light in weight. In addition, relative to fluid transmission, materials are to be developed, which are highly resistant to heat, corrosion, and thermal impact, and capable of separating and removing particulates of powder dust. Under subject 2), efforts are under way to develop two technologies, related to materials creation and their application. The former technology involves the development of a process of simultaneously equipping materials with high wear resistance, desired friction factors, and desired mechanical and thermal characteristics; a process of equipping them with a trace damage detecting function; and a process of simultaneously equipping them with functions of restoration from accidents and of self-lubrication. Relative to the latter technology, efforts are conducted, in coordination with the endeavors for the above-said materials creation technology, to develop materials and their application with attention paid to some specified functions. Under subject 3), self-complete type ceramic materials not requiring an external driving power source are to be developed, in which a selective cleaning function and environmental energy conversion function are amalgamated.

    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.

    This paper describes efficiency improvement in wastewater treatment to separate SS component using anaerobic fermentation with fixable microorganisms and multihole glass separation films. Measurement of microorganism deposition on microporous PVF resin in a fermentation tank revealed that hydrophilic resins with smooth surface have better deposition, and the suitable carrier hole diameters were from 300[mu]m to 500[mu]m. Adding slightly-soluble carbonate when bacteria are fixed collectively is effective in preserving the entire methane fermentation reaction system and stabilizing the carriers. A composite film comprising SiO2-ZrO2-based porous glass made by using a sol-gel process and porous ceramics had the maximum desalination rate reaching 90%. The permeation rate at a film thickness of 2[mu]m was 46 times as much of that for 500-[mu]m single-layer porous glass. As a result of reforming the pore surface by introducing -Si(CH3)3, the film has turned affinitive to non-polar solvent, repelling water to permeate. In an experiment for fermentation liquid permeation of separation film composite bioreactor using digestive sludge, the higher the SS particle concentration, the more the initial clogging was difficult to occur. The film permeating flow velocity showed a maximum value at hole diameters of about 0.2[mu]m. 3 refs., 6 figs., 2 tabs.

    A coral skeleton is sampled at Kenya`s Malindi National Marine Park situated west of the Seychelles, and it offers information about the Afro-Asian monsoon. An X-ray profile of the specimen discloses the seasonal variation in the density of the coral skeleton. The oxygen isotopic ratio, which is generally affected by the seawater oxygen isotopic ratio composition which is dependent on the surface layer water temperature and fresh water, is found dominated, in the coral skeleton, practically by the surface layer water temperature. Accordingly, the oxygen isotopic ratio represents the seasonal and annual variations in the surface layer water temperature. It is inferred that the emergence of Ba/Ca ratio peaks in December into January reflects the presence of Ba from rivers, and there are indications that the Somali current has transported water to the coral sampling area from the Galana River which is the greatest river in Kenya. Five of the Ba/Ca ratio peaks coincide with peaks in the UV fluorescent band, which is attributed to the presence of terrigenous organic matters. The ENSO and Asian monsoon phenomena are estimated on the basis of the findings described above. 11 refs., 6 figs.

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

    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.

    Very fine structure control technique for amorphous and nanostructured metallic materials was reviewed to exceed the marginal performance of small metallic member materials. In Japan, high strength alloys and anticorrosion alloys are currently developed as an amorphous structure control technique, and ultra fine powder production and nano-compaction molding are studied for nanostructured materials. Fabrication of amorphous alloy wire materials and metal glass in USA are also introduced. Fabrication of metallic nanocrystals deposited within gas phase in Germany are attracting attention. The strength and abrasion resistance are remarkably enhanced by making nanostructured crystals and dispersing them. It may be most suitable to utilize amorphous and nanostructured metallic materials for earth-friendly materials having anticorrosion, and catalyst and biomaterial affinities, and also for magnetic materials. It is important for controlling micro-structures to clarify the formation mechanism of structures. For their processing techniques, the diversity and possibility are suggested, as to the condensation and solidification of gaseous and liquid phase metals, the molding and processing of very fine solid phase alloys, and the manufacturing members by heat treatment. 324 refs., 109 figs., 21 tabs.

    Liquefaction is applied to various biomass wastes and unused biomass to study characteristics of the liquefaction in each case. 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.

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

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

    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.

    With an objective to achieve higher efficiency, higher density, and higher stability in power systems, research and development has been performed on superconductor power applied technologies. This paper summarizes the achievements thereof in fiscal 1999. In research and development of the superconductor wire materials, decrease in loss and increase in capacity of the conductors were progressed for the Nb{sub 3}Sn wire material, whereas its mechanical properties and stability were evaluated. In research and development of the superconductor generators, an ultra high speed responding generator was verified of its healthiness in a sudden short circuit test. A linkage test with an operating 77-kV system was performed, wherein verification was given that the superconductor generator can be operated stably against various disturbances. In research and development of the freezing systems, an improved system was structured, which achieved operation of 11,390 hours in a single system as a result of the high reliability of the oil-free structure. In the verification tests, the ultra high speed responding model generator was connect to the freezing system to give such tests as load test, onerous test, actuation test by using the M-G system, and 77-kV system linkage test. The functions, reliability, and durability of the system were verified, and different data were acquired. (NEDO)

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

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

    This paper describes problems concerning carbon balance and nutrient salt in coral reefs. Coral reefs fix CO2 in two forms of organic matters and calcium carbonates. It is reported that 10% of organic matters fixed by photosynthesis may either be buried in deposits on coral reefs or flow out into open seas. Quantification of the carbon balance in coral reefs has a problem of handling organic matters in calcium carbonate skeletons as products, and a problem related to evaluation of organic matters flown out from ecological systems. Corals provide, through building foundations at shallow depths, living organisms carrying out photosynthesis with locations abundant in quantity of light. Coral reefs are thought to accumulate nutrients in their skeletons or in the foundations for deposits. They would hold nitrogen in them through nitrogen fixation, and maintain phosphor production at high levels by retaining nitrogen-to-phosphor ratio which is relatively lower than in other ecological systems. Coral reefs provide foundations to transparent sea water with extremely small amount of phytoplankton, and favorable environment for large-size animals and algae. 21 refs., 2 figs.

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

    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.

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

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

    With an objective to establish basic technologies, research and development has been carried out to make it possible to utilize high-temperature superconductor materials in terms of engineering in the fields of electronics and electric power. In the research on superconductor materials in fiscal 1992, it was discovered from measurements of temperature change in polarization dependent EXAFS in thin YBCO film grown on an MgO substrate that relative displacement in copper atoms in CuO{sub 2} plane and peak oxygen, and relative displacement in copper atoms on a primary chain and peak oxygen show apparent increase at the critical superconduction temperature. It was verified that this phenomenon does not occur in materials that do not show superconduction. In the research and development of superconductor elements, full-swing research has begun toward establishing the following technologies: process technologies for a substrate that meets requirement of surface flatness required in electronic elements, a superconductor thin film that assures uniformity in interface composition and the laminated thin film tunnel junction that combines the superconductor thin film, an inter-layer insulation film, and ultra-fine processing to suppress deterioration, and a tunnel element technology as a technology to put the above technologies together.

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

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

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

    A low-cost production method is developed for monosilane as a cell film material, 99.9995% pure at a manufacturing cost of 4,500 yen/kg (100 ton/year unit). An experimental unit with a maximum capacity of 1m{sup 3}/H (1 ton/month) gas production is built, and whether it is practical will be clarified by the end of fiscal 1983. The whole monosilane production process, consisting of the electrolysis of eutectic liquid of Li chloride and K chloride, hydrogenation of Li to be generated by the electrolysis, and the generation of monosilane through the reaction of the hydrogenated Li and silicon tetrachloride, proceeds in one large molten salt tub. The chlorine from the electrolysis and Si as material comes into reaction in a salination furnace for the generation of silicon tetrachloride to be supplied to the process. Minor tests are made involving pressure control, distance between the electrodes and the effect of the diaphragm, stirring in the hydrogenation chamber, dust in the monosilane generation chamber, and the insulation of the cathode lead rod, and the results are reflected on the process of experimental unit designing and building. The unit has harm neutralizing facilities for safety assurance because much hydrogen and a little chloride are consumed while the unit is in operation, with some silicon tetrachloride to be retained in the unit. An infrared absorption method is used to analyze impurities in the monosilane gas, when the method exhibits a capability of detecting 2ppm of methane. (NEDO)

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

    This paper describes the achievements in development of brown coal based solvent extraction in the Sunshine Project in fiscal 1981. Element researches were performed to complement and support the development of a liquefaction technology for brown coal produced in Victoria, Australia by using a 50-T/D pilot plant. For the primary hydrogenation technology, a manufacturing experiment was completed by means of nine cycles using a brown coal balancing solvent in a 0.1-t/day bench scale test. Distribution of the formed materials, the solvent properties, and the SRC properties have become nearly constant after 5 to 6 cycles. A test using a batch type device was performed to derive the relationship among dissolution parameters, SRC recovery rates, and deliming rates by using different solvents. For the secondary hydrogenation technology, SRC being the heavy fraction in a primary hydrogenation system (+420 degrees C) was hydrogenated by using an Ni{center_dot}Mo based catalyst at 360 degrees C and 250 kg/cm{sup 2}. A prospect was attained that the processing is possible by using a fixed bed reactor. A test using a small continuous dehydration testing device was carried out by using creosote oil as the solvent and by varying the evaporator operating conditions. Dehydration rate of 90 to 95% was obtained. Discussions were given on selecting catalysts for the secondary hydrogenation of the fixed bed method, and on factors of activity deterioration. A secondary hydrogenation test reactor of the suspended bed method was completed. (NEDO)

    When discharge plasma is applied for film formation, ions affect the quality of the resultant film. In the case of plasma CVD (chemical vapor deposition) method, there exists correspondence between the radicals ratio SiH/H and solar cell conversion efficiency, and plasma measurement may be used for the control of film formation conditions. The state of distribution of radicals in discharge plasma is dependent on the type of radicals, and there is an optimum substrate position. Photoelectric characteristics are improved when a grid electrode is used for plasma separation. The surface of a transparent conductive film (ITO: indium-tin oxide) to be the substrate for film formation needs to be flat, and part of its Si is oxidized into SiO{sub 2} by generated oxygen. An ITO film coated by chemically stable SnO{sub 2} is useful. When the ion plating method is employed, film formation conditions are first selected, and then, in a heat treatment to follow, resistance films of various surface conditions are obtained. Carbon-added a-Si film formation conditions and the relationship between film qualities and solar cell characteristics are elucidated. In a solar cell of the p-i-n structure with an a-Si:C:H film acting as the p-layer, a conversion efficiency of 7.6% is achieved. (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.

    The operation of a 1t/d PSU (process support unit) was studied in the NEDOL coal liquefaction process. Modification was made, which involved the installation of a high-temperature/high-pressure sampling device for observing reaction and fluidity in the liquefaction reactor, a differential pressure measuring device, and a neutron attenuation-aided measuring device. Relative to coal injection, a 49.5-day and 49.3-day slurry injections were carried out using Tanito Harum coal, when impacts on the product yield and the operability of the unit were examined. A verification test was conducted for an improved hydrogenation catalyst, and liquefaction reactor characteristics were investigated. During a 19-day operation for the study of maintenance, newly installed equipment and devices were verified for function, and operating methods were probed into. In the survey of environments, characteristics were examined of the wastewater discharged from the Tanito Harum coal liquefaction process, and wastewater treatment methods were studied. The air, odor, and tar mist were examined with the PSU in operation, and the measured values were found to be below the management limits showing that its operation did not pose any problems relating to working environments.

    By developing 100W class micro-inverter and putting it to the solar cell panel one by one, a control system is developed by which the maximum output can be obtained as the solar cell system even if the output of individual panels changes by stain and shade. By this system, power generation efficiency is expected to be increased by approximately 10%. In case that power generation of 5 million kW is achieved in FY 2010, energy conservation of about 50,000 kl/year in oil conversion can be expected. In FY 2000, the following were carried out: 1) investigational study of electronic parts; 2) primary trial-fabrication of micro-inverter; 3) various kinds of simulation assuming the inverter parallel operation. In 1), two kinds using the fly-back transformer method and the immittance conversion theory were trial-fabricated. As to the former, the main circuit method was designed to be the fly back type high frequency insulation method, and the control method to be the pulse area modulation method. As to the latter, the current output type power converter was structured by the circuit simulation. (NEDO)

    In fiscal 1999, the power conditioner which is the primary component of a photovoltaic power system was subjected to an accelerated test, etc., for the evaluation of its durability. For the accelerated test, operating conditions were so set that acceleration be implemented according to Arrhenius' law at ambient temperature 40 degrees C and relative humidity 36%. For the operation of the power conditioner, it was so set that the operation duration be 3.5 hours with a rest time of 4.5 hours for the night or the like. In the accelerated test conducted as in the previous year, 1100 cycles were completed recording the maximum, equivalent to approximately 8-1/2 years according to Arrhenius' law. After the test, no life affecting changes were detected in specimen device A, B, or D. Specimen C, however, failed during the test. As for the evaluation of durability of components, the electrolytic capacitor in the power conditioner was named. Reliability related literature was investigated and a durability evaluation test was started, with consideration given to the voltage to apply and service temperature. (NEDO)
