    Researches have been performed on water decomposition by multiplex utilization of solar beam, and the achievements in fiscal 1984 were reported. In fiscal 1984, activity coefficients for iron ions and iodide ions having been discussed by the previous fiscal year were derived, and free energy variation amount and accumulated energy amount generated as a result of photo-chemical reactions were derived. Values derived in the experiment were low, which are the values at room temperatures, and higher values are expected under elevated temperatures. In an experiment using a beam irradiation electrolytic tank, investigations were made on thermo-chemical isolation and electrolytic isolation of HI. Since HI is strongly acidic, it does not get liberated unless phosphoric acid concentration and temperature are increased, which is a condition opposing to easiness of the photo-chemical reaction. Therefore, an experiment on HI was performed not only on isolation due to heat, but also isolation by electrolysis, where the intended result was obtained. The mixed system of a photo-chemical system and an electrolytic system requires a system configuration that considers dynamic matching conditions, for which a system to perform measurements simultaneously on a large number of kinds was found effective.

    The research and development aims to increase the yield of light energy conversion in a photochemical reaction and thereby to increase the efficiency of the reaction of electrolysis of water. In the research, the electrochemical properties of Fe{sup 3+}/Fe{sup 2+} and I{sub 3}{sup -}/I{sup -} systems in a phosphoric acid solution are examined. As for the behavior of iodine ions I and I{sub 3}, their capacity coefficient rises with a rise in temperature at any phosphoric acid concentration level. Furthermore, more water molecules are disengaged from hydrated iodine ions with an increase in the concentration of phosphoric acid, and the now naked iodine ions are higher in activity coefficient. The behavior of iron ions in phosphoric acid is observed by use of a rotating electrode. Although the activity coefficient ratio of iron ions and iodine ions exerts a great influence in the process of conversion from light energy to chemical energy, the outcome of experiment indicates that the ratio is low for both iron- and iodine-based systems. It is consequently concluded that an energy conversion rate of approximately 10kcal/mol is expected from a photochemical reaction as in the case of hydrated systems. (NEDO)

    Reported herein are the FY 1985 research results on the combined water electrolysis cycles by effective utilization of sunlight. The tests for determining activity coefficient of an iron/iodine system is continued from the previous year, and the results are used to find the optimum conditions under which the photochemical and electrolysis reactions are effected simultaneously in a light-irradiated electrolysis tank. It is found that a photochemical reaction efficiency of approximately 0.3% is obtained at 5 W/cm{sup 2} as light intensity and 25 degrees C. For electrolysis of water by the multi-stage hybrid cycles, it is necessary for the reaction in each stage to proceed to almost the same extent so that it gives a just enough quantity of product for the subsequent stage. The data obtained are analyzed comprehensively, while taking the system matching conditions into consideration. The system for simultaneously measure two or more parameters, developed in the previous year, is equipped with a high-level language compiler of high effective speed, to simultaneously measure these parameters at shorter intervals.

    The report covers the outcome of a basic study of the splitting of water using photochemical reaction. The behavior of iron ions and iodine ions is important in the photochemical reaction in the phosphoric acid and in the energy exchange that follows, and the characteristics of iodine ions are investigated in detail. Since the response of a commercially available iodine ion electrode is slow in a strong phosphoric acid solution, a silver/silver iodide electrode is experimentally built, and is used in the investigation of the iodine ion activity coefficient. In the investigation, it is indicated that more energy is accumulated when temperature or concentration is higher. In the case where sunlight is used as the light source for photochemical reaction, it is necessary to perform optimal control in compliance with fluctuation in sunlight intensity. In the study, fluctuation in sunlight intensity is assumed to be composed of step waves, pulse waves, and sinusoidal waves, and a result of digital simulation is obtained by using a modelling method for control. For the convenience of computation, the number of cell division is set at approximately five, when the solution flow responsiveness and energy conversion utilization factor are found to be excellent.

Basic technologies are developed for a method to automatically measure B and Be. The detection limit of the technology for Be is 7.2ppt, which means that it can be used for monitoring the working environment reference level for Be.

    This paper describes research achievements in fiscal 1978 on water decomposition by using the thermo, photo and electro-chemistry mixed cycle. Fundamental experiments were carried out in a photo-chemical and electrolytic reaction tank to electrolyse as quickly as possible HI and iron (III) produced by photo-chemical reaction in the iodine-iron (II) system, and separate the products therefrom. The photo-chemical reaction was analyzed by using the spectro-photometry, and the degree of reaction progress was quantified by using the change in absorbance of I{sub 3}{sup -}. Since temperature rise due to sun beam irradiation accelerates reverse reaction, the apparent equilibrium position under the beam irradiation was moved from the product system to the original system as the temperature rises. An expression showing the reaction efficiency was introduced to indicate that beam collection enhances the efficiency. There is no electrolytic electrode material that reduces only iron (III) preferably, and electrolysing the aqueous product solution as it is results in low energy efficiency. In addition, as a result of discussing factors affecting the effect of HI decomposition (to acquire hydrogen) by using a heat diffusion column, it was revealed that maximum separation effect can be derived if the material is fed from the center of the column. Discussions were given also on other factors. (NEDO)

    Discussions are being made on manufacture of hydrogen and oxygen from water decomposition using mixture cycles composed by thermo-chemistry, photo-chemistry and electrochemistry using ferrous sulfate and iodine. Photo-chemical reaction produces Fe(OH)SO{sub 4} and HI, but due to difficulty of isolating Fe(OH)SO{sub 4}, photo-chemical reaction that can obtain the compound as Fe{sub 2}(SO{sub 4}){sub 3} was introduced. A method was introduced that can perform HI isolation simultaneously while performing reaction to reduce Fe{sup 3+} and turn it into Fe{sup 2+} (generating oxygen) by means of electrolysing the liquid after the former reaction. The electrolytic process decomposes HI into hydrogen and iodine (discussions on thermo-chemical decomposition is also continued). Since the photo-chemical reaction can cause reverse reaction, discussions were given on the reaction process in order to suppress the reverse reaction and enhance the conversion efficiency. This paper describes the achievements during fiscal 1977. A quantification method was elucidated on individual iodine components so that it can be used for computerized control (measurement of absorbance of I{sub 3}{sup -}) . An electrolytic tank was discussed that decomposes and isolates photo-chemical reaction products before the reverse reaction occurs. Heat diffusion method was also discussed that isolates hydrogen from HI decomposition products. (NEDO)

    This paper describes achievements in research and development in the Sunshine Project in fiscal 1979 on water decomposition by using mixed cycle of thermo-chemistry, photo-chemistry and electrochemistry. In research on the light irradiation electrolytic process, with an objective of improving the reaction efficiency, discussions were given by raising light intensity on the irradiated surface as high as 13 times that of the sunlight. The subsequent process is electrolysis of products from photo-chemical reaction, and the product concentration should be high enough to have HI decomposition (hydrogen acquisition) proceed with high efficiency. Experiments were carried out at 0.03 to 0.1M as iodine concentrations (product HI concentration at 3%). A photo-chemical reaction rate of 80% was obtained at light intensity as high as 12 times that of the sunlight, and iodine concentration of 0.07 mM. The efficiency was 15%. Raising temperature causes the reaction rate to decrease, but it can be supplemented by raising the light intensity, where high concentration HI content was obtained. Rate controlling process in the reaction was elucidated from activation energies in the reaction process of each element on the iodine concentrations from 3 to 30 mM used in the photo-chemical reaction. Experiments were performed on HI decomposition (hydrogen acquisition) by using a heat diffusion column. Separation performance in a filled type column was worse than that in an empty type column, which requires future discussions. (NEDO)

As the chemical analysis method, used was inductively coupled plasma atomic emission spectrometry. To study the relation between the methods, it was found to be necessary to recognize morphology at the boundary between the coating and base steel using, for example, scanning electron microscope (SEM) and electro-probe micro-analysis (EPMA). To measure traceability of the analysis method, with the chemical analysis method as a judgement method, it is necessary to make reference materials by coating materials, to use the calibration graph confirmed by the materials and to adopt the glow discharge optical emission spectrometry. On the basis of such way of thinking, drafts were worked out for the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. 7 refs., 117 figs., 33 tabs.

    This is a study on how chemical terms used in Japanese chemistry textbooks correspond to those in American textbooks. Examples in which English and Japanese chemical terms do not correspond are divided into 4 groups, and points to be noticed are described. As references, two kinds of most popular textbooks in the U.S. and three kinds of Japanese textbooks are mainly used. When chemical terms in either of American or Japanese textbooks do not correspond to or were not found in the other textbooks, several kinds of other dictionaries and textbooks are also investigated. As a result, it is found that there are some English terms which are apt to be mistranslated into Japanese. Some of English translations established in dictionaries and textbooks in Japan are not found in American textbooks. In the same way, some English terms often used in American textbooks do not appear in Japanese textbooks and dictionaries. These examples and notes seem to be useful for reading American textbooks or writing English abstracts of papers on chemistry. 16 refs.

    In chemical materials there exist hazardous materials causing health damages, environmental pollution, fires and explosions. The hazard analysis has been noted as a means for preventing accidents due to chemical materials. This means leads to an effective method of recognizing hazard, evaluating the risk, and lowering the degree of hazard to an allowable level. This paper describes a hazard analysis of autoreactive materials, out of chemical materials causing fires and explosions, which may react by theirselves and cause accidents. In particular, an example is introduced in which this hazard analysis method is adapted to an experimental production of the next generation gas generating agent for automobile collision safety air-bags. In this manufacturing process, in kneading and granulating processes where lots of materials are handled, materials are used in a moistened state, thus countermeasures for preventing occurrence of combustion and explosion being taken. 5 refs., 2 figs., 4 tabs.

    Fog samples were collected for analysis at Mt. Ohyama, the east edge of Tanzawa Mountains in the southwest of Kanto plains. Then, rainwater and aerosol that becomes the core of droplet were analyzed and measured values were compared. As a result, the pH value of the fog samples for 2 years from 1988 to 1990 ranged between 2.6 and 7.0, and the mean pH value was 3.95. According to the measurement of major component concentration of fogwater, rainwater, and aerosol, it was found that concentration of fogwater changed significantly depending on the day but every ion concentration was higher than that of rainwater. The equivalent concentration ratio of sulfuric acid, nitric acid, and chloride ions were almost equal. The concentration value of fogwater varied a lot with the course of time and became higher during the formation and the dissipation of fog. Through the analysis of such changes, atmospheric scavenging effect of precipitation of fogwater upon the trees and the earth surface was observed. It means that pollutants with high concentration were loaded on the plants and the earth surface. 23 refs., 5 figs., 2 tabs.

    Since light can be transformed into electricity, electrolysis of water using light is possible naturally, and photosynthesis in the nature is based on this principle. The reaction field in which electrochemical energy necessary for decomposition of water is generated using light at the first process of photosynthesis is a biofilm less than 10nm thick which is called thylakoid film. In this article, the effects are roughly explained which have been made for constructing an artificial system corresponding to the thylakoid film. Accumulation of knowledge of the molecular level is necessary for the construction of the artificial system and the three dimensional structure concerning the reaction center of photosynthetic bacteria has been determined. At the reaction center, oxidation species of electron donor and reduction species of electron acceptor are generated by charge separation which succeeds electron excitation by light energy. In order to lead the above process to materialistic production, efforts are being made for construction of a reaction center model compound for artificial photosynthesis from both physical chemistry and organic chemistry and the positive results have steadily been obtained in the development of photocatalysis of a semiconductor. 9 figs.

    1995-01-05

    Upon explaining the origin of the word `paradigm`, and interpreting the word as `current` or `trend`, this paper describes mainly the current with which the `freedom of research` is getting lost. When groups of engineers made a debut as vocational groups in the 19th century, researches were performed as a manifestation of curiosity and the will of truth pursuit of individuals, and the `freedom of learning` and `freedom of researches` were guaranteed in the first priority partly because the `free competition` had reached the summit in the then society. The clear current in the latter half of the 20th century is represented by the phenomena of increased research scales and the `regulated research activities` associated with the idea of enhancement of the national prestige. The prerequisite under these states of affairs was the return of the results to the society both publicly and privately. Under the pressure of environmental problems, it is estimated that the trend of `international` regulation will get stronger in terms of adjustment, distribution and priority of production. How a research based on `curiosity` of an individual is guaranteed under such circumstances depends upon out selection.

    This paper summarizes studies on evaluation of breeding and bio-degradability of decomposition bacteria in bio-remediation, and births and deaths of microorganisms. Structural genes in a phenol decomposition path were separated by means of shotgun cloning. The phe B genes having been taken out were inserted into parent stocks to produce combined stocks for use in phenol decomposition. With 100 mg/l of phenol, the combined stocks showed better performance in both decomposition and multiplication than the parent stocks. When the phenol concentration increases, the rate controlling process changes and loses its effect. Decomposition of trichloroethylene progressed quickly with combined stocks derived from phe A, a phenol decomposed gene. Separated polyvinyl alcohol (PVA) decomposing bacteria were used for PVA decomposition. As a result, it was found that microorganisms are required that utilize intermediately produced low-molecular compounds for multiplication. Combined stocks with E. coli C600 stocks inserted with phe B were prepared to discuss births and deaths of microorganisms in activated sludge. A number of findings was obtained. 6 refs., 10 figs.

    Suppression at a source is the principle of suppressing air pollution caused by vapor phase chemical substances. For the case of these substances with extremely low concentrations, discussions were given on decomposition by means of photocatalysts (that utilize solar light) to directly purify them in the atmospheric condition. Catalysis takes place in providing and receiving electrons, that is, oxidation and reduction of the electrons, under light irradiation by using photocatalysts in which light excites and causes internal electrons to migrate freely. Titanium oxide was found effective because it is high in catalytic activity, stable chemically, and harmless. Photodecomposition reaction of chlorinated organic compounds on TiO2 proceeds very fast except for fluorocarbons. In practical use, the catalyst must be fixed so that no catalyst powder will scatter around. Porous TiO2 sheets were, therefore, manufactured using fluorine resin as a binder. The sheets were used to have removed successfully NOx, SO2 and low-grade aldehyde with concentrations from 0.01 to 10 ppm (corresponding to gases discharged from a tunnel). Since the catalyst can function even under solar light, it can remove NOx during daytime, and can be regenerated by precipitation (passive environment purification). The catalyst was verified effective when used on roads in urban areas. 16 refs., 9 figs., 3 tabs.

    A survey was conducted of bio-chemical complex harmonized with the global environment for the purpose of constructing the material production process harmonized with the environment by the process fusion between biological conversion and chemical reaction. Palm oil was taken up as renewable raw material plant resource. The process utilizing bio-chemical reaction advances at normal temperature and pressure and is high in reaction specificity and selectivity. This is a recycling, circulation and environmental harmony type production technology which brings high yield, energy conservation, resource conservation, and low environmental loads. Waste water treatment and production of useful substances from sludge were thought as elementary technology. A possibility was studied of enzyme production by culturing solid waste, and the enzyme was applied to the hydrolysis process. The paper indicated trace components in the palm oil and the extraction method and proposed the production process of new derivatives for adding value to hydrolysate. A study was also made of the overall process flow which integrated these new processes and the material balance. The comprehensive evaluation of this new process was made from the aspect of the product structure, the market, construction cost, economical efficiency, and the environment. 133 refs., 65 figs., 56 tabs.

    Through the hydrogenolysis of Wandoan coal and Tanito Harum coal which are used for the NEDOL process, differences of liquefaction characteristics between them were found. The purpose of this study is to grasp these differences as differences of chemical structures of oil fractions. The compound type analysis was conducted for oil fractions obtained at varied reaction temperature for varied reaction time. Coal liquefaction characteristics of these coals were discussed by relating oil yields and chemical structures. For Tanito Harum coal, yields of gas and oil were considered to be lower than those for Wandoan coal, which reflected that the contents of partially hydrogenated hydroaromatics in oil fraction from the former were lower than those from the latter, and that the remarkable change of composition did not occur with the progress of the reaction. For both the coals, the remarkable changes in the average molecular weight of oil fraction were not observed with the progress of the reaction. While, the content of methane gradually increased with the progress of the reaction, which suggested that oil was gradually dealkylated. 5 figs.

    Considerations were given from a viewpoint of assessing toxicity to human bodies on methods of assessing water pollutants and organisms, and applicability of cytotoxity test using cultured cells to water quality assessment. Biological assessment systems used for water environment may use tests using multicellular organisms, cells, or organelles in cells. The organism assessment method is intended mainly for assessing ecological effects, and a suitable method must be selected upon extrapolating it to human bodies. A toxicity parameter used most frequently in a cytotoxity test is the cell revival rate, and life and death are determined from liberation of enzymes in cells, or with color rejection tests and incorporation tests. There are a number of test specimens of raw tap water and its chlorine treatment condensate that show no mutagenicity but cytotoxity. Efficiencies of removal by means of mild chlorine treatment, fast filtration, and activated carbon adsorption vary greatly with cytotoxity and mutagenicity. Introducing the cytotoxity test is expected of further contributing to improving safety in water quality. 24 refs., 1 fig., 7 tabs.

    The solid state polymer electrolyte type electrochemical cell (PEMFC) has such problem that the gas diffusion from the resin surface to the catalyst surface is prevented when the coating thickness of cation exchange resin on the catalyst particle and the number of micropores which conduct the gas flow in the catalyst layer are reduced. Resultingly, a sufficiently large current cannot be taken out of the cell. This invention solves the problem. The catalyst layer of electrode of PEMFC consists of a mixture of the conductive catalyst carrier coated with cation exchange resin and the conductive carrier coated with fluorinated hydrocarbon polymer. Adding the water repellent material to the electrode in this way improves the air-passing porosity. As for the cation exchange resin, perfluorocarbon sulfonate or perfluorocarbon carboxylate can be used. For the fluorinated hydrocarbon polymer, fluorinated polyethylene is preferably used. 4 figs., 2 tabs.

    This paper introduces the following technologies and countermeasures found to be successful in solving geochemical problems relating to the maintenance and management of geothermal power plants belonging to Kyushu Electric Power Co., Ltd. In controlling condensate properties,curtailment of pH fluctuation range by changing the injection point of NaOH,inactivation of sulphur bacteria by using chloramphenicol and prevention of slime loading of the condenser strainer by running of the cooling tower without make-up water were achieved. In the environmental countermeasures,it was concluded that Fe-ion injection method was most effective to remove As out of waste hot waters which are all reinjected into the underground formation now. By understanding the characteristics of the well eruption fluids,the attenuation mechanism of steam producing wells could be estimated, which were interference,re-eruption and degradation of the reservoir temperature caused by the reinjected hot waters. And the problems associated with the attenuation of steam producing wells have been solved fundamentally by taking proper countermeasures to eliminate the influence of reinjected hot waters. The atteunuation of reinjection well was found to be caused dominantly by silica loading at the permeable zone of wellbore and to be effectively solved by high temperature reinjection of the waste hot waters, controlling of temp. degradation of hot waters to be reinjected and prevention of air mixing. After applying proper countermeasures, the attunuation rate of the reinjection well has been fairly improved. 13 refs., 21 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.

    The aim is to improve on hydrocarbon oxidation which is a difficult reaction (analogous to combustion and having potential for heat generation or explosion, with restrictions therefore imposed on reaction conditions) by use of a catalyst supporting porous membrane. The fiscal 1999-2000 results are stated. In this effort, the target reaction is promoted by a catalyst supported by a porous membrane while combustion is controlled by the said porous membrane that separates oxygen and hydrocarbon from each other. Such a design was not available since a catalyst supporting inorganic membrane withstanding so high a temperature was difficult to prepare. Recently, however, a porous membrane with its pores regulated to microstructural dimensions was developed. The activity of a Pd membrane catalyst is evaluated in view of the degree of oxidation of propylene, cyclohexene, and benzene. It is then found that hydrogen that has passed the Pd membrane participates in the reaction. In a propylene oxidation test using a membrane type Ag/Al{sub 2}O{sub 3} catalyst, it is found that acetone is generated and that oxygen after passing through the membrane participates in the reaction. Methods are studied for preparing a metal membrane in which the catalyst system comprises a catalyst supporting porous membrane and a Pd membrane. In the fabrication of metal membranes, a highly selective hydrogen permeable membrane is stably prepared by the thermal CVD (chemical vapor deposition) method. (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.

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

    The present paper suggests chief measures to suppress and reduce global greenhouse gases. Under the control of artificial environments such as bioreactor, hydroponics and vegetable factory, a very high fixing rate of CO2 can be obtained, but CO2 generation accompanying electric power consumption is also large. It is preferable to use methane as resource by reforming reactions or selective oxidative reaction. In the recovery technique of fluorocarbon, 100% recovery is desirable. Techniques for decomposing recovered fluorocarbon and converting it to harmless material are the most backward ones. Understanding of essential structural relationship of coal is necessary for establishing combustion technique for the reduction of N2O. The integrated power generation system composed from solid electrolyte type fuel cell and coal-gasifying process, high-performance, superheat pump system form scientific technology imposing no burden on the global environment. Establishment of purification technique for industrial- or living-related drain inflowing to a closed water area system, establishment and reinforcement of inspection system for oil spill in the oceans in a global scale are required. 240 refs., 63 figs., 30 tabs.

    Although various chemical reactions are made use of at scenes of chemical industry for the acquisition of desired chemicals, the control of reaction process governing factors, such as temperature, pressure, catalysts, solutions, etc., is found to be carried out only on the empirical basis. At the present time, rational or optimum reaction designs are not to be prepared in a short period of time in the presence of the widespread shortage of knowledge about chemical reactions and of the shortage of understanding of chemical reactions at the micro level. Leading survey and research are conducted for the development of a 'chemical reaction simulator' technology to enable the acquisition of optimum reaction designing guidelines in a short period of time. Using the simulator, a chemical of his choice is inputted by a researcher engaged in the study of an real chemical reaction and then various techniques of computer science are mobilized for the preparation of a huge number of feasible reaction routes, and high-precision simulations are conducted for the feasible reaction routes. The results achieved this fiscal year are reported. The purpose of this research and its ripple effect on new product industry creation are stated. Then the positioning, mission, and concept of such a chemical reaction simulator are described. Finally, the result of research and survey of knowledge databases and the result of research and survey of computational chemistry are stated. (NEDO)

    In order to structure a chemical reaction process that does not discharge a large amount of waste by-products or harmful chemical substances, or so-called environment friendly process, investigations and discussions were given based on the results derived in the previous fiscal year. A proposal was made to reduce environmental load on development of oxidized and dehydrogenated catalysts that can produce selectively ethylene, propylene and isobutylene in an oxidation process. In liquid phase oxidation, redox-based oxidation and solid catalyzation of automatic oxidation reaction were enumerated. In acid base catalyst reaction, development of ultra strong solid acid was described to structure no pollution discharging process. In the fine chemical and pharmaceutical fields, the optical active substance method and the position-selective aromatics displacement reaction were evaluated to reduce environmental load. A questionnaire survey performed on major chemical corporations inside and outside the country revealed the following processes as the ones that can cause hidden environmental problems: processes discharging large amount of wastes, processes treating dangerous materials, and processes consuming large amount of energy. Development of catalysts is important that can realize high yield, high selectivity and reactions under mild conditions as a future environment harmonizing chemical process. 117 refs., 23 figs., 22 tabs.

    The baking process in cement production means the process that the raw materials which were mixed and pulverized in the raw material preparation process are charged into a reaction furnace which is called kiln, and clinders (intermediate product of cement) are generated. It is the process which affects quality as well as production cost of cement more significantly than anything else. In this article, an outline of the above baking facilities, how the raw materials change and clinkers are generated therein, and how they are controlled are introduced. Clinkers are composed of such products as alite, belite, aluminate and ferrite, etc. which were generated after decomposition reactions of such raw materials as lime stone, clay, silica rock and iron oxide in the above kiln. The essential ponts of the process control which makes the generation reactions of clinker compounds efficiently are such two points as well balanced raw materials to be charged into the baking facilities and stable operation of such facilities. The quality of cement which is required as finished goods is achieved by the quality control at each intermediate process and the quality tests of cement. 5 refs., 10 figs., 2 tabs.

    Although various chemical reactions are made use of at scenes of chemical industry for the acquisition of desired chemicals, the control of reaction process governing factors, such as temperature, pressure, catalysts, solutions, etc., is found to be carried out only on the empirical basis. At the present time, rational or optimum reaction designs are not to be prepared in a short period of time in the presence of the widespread shortage of knowledge about chemical reactions and of the shortage of understanding of chemical reactions at the micro level. Leading survey and research are conducted for the development of a 'chemical reaction simulator' technology to enable the acquisition of optimum reaction designing guidelines in a short period of time. Using the simulator, a chemical of his choice is inputted by a researcher engaged in the study of an real chemical reaction and then various techniques of computer science are mobilized for the preparation of a huge number of feasible reaction routes, and high-precision simulations are conducted for the feasible reaction routes. The results achieved this fiscal year are reported. The purpose of this research and its ripple effect on new product industry creation are stated. Then the positioning, mission, and concept of such a chemical reaction simulator are described. Finally, the result of research and survey of knowledge databases and the result of research and survey of computational chemistry are stated. (NEDO)

    As part of establishing an environmental harmony type production system of chemical products, study and survey were made on PET bottles. Using the life cycle analysis method (LCA), a study was made for proposing a material recycle (MR) method which is environmentally and economically excellent in the stage of recycling waste PET bottles. The total cost of recycling can be reduced by 34% supported by a decrease in equipment cost and improvement in yield if there is no mixture of foreign substances such as aluminum caps and PVC bottles. However, the ratio of the amount obtained from the reduction to the total production cost is small, and it is necessary to take measures from a viewpoint of the cost in a total production process and environmental loads. In a survey in Kawaguchi city, PET bottles discharged from the business sector occupied 41% of all the discharge amount. In a survey in Yokohama city, very important data were obtained on PET bottles appointed as the second type under the recycle law. The quality of PET bottles to be brought to the recycling plant is important for effectively processing PET bottles in MR method. For achievement of MR which is low in cost and small in environmental load, needed were cooperation by citizens, the shipping management system in autonomous government, and changes in design and material quality to be made by the industrial circle. 8 refs., 64 figs., 68 tabs.

    This report presents the new technologies of chemical management in Higashi-Niigata Thermal Power Station. 1. Development of New Turbine Oil with Improved Oxidation Stability We examined the effect of the dosage of DBEP as an oxidation inhibitor on oxidation stability. As a result, the newly developed turbine oil has about 30% higher oxidation stability than the conventional turbine oil. 2. Extended Interval of Chemical Cleaning for Circulation Boiler We carried out an actual plant test using the JIS guaranteed reagent (sodium phosphate) instead of the conventional chemical. As the JIS guaranteed reagent has few corrosive compounds, the corrosive rate of water-wall tubes was decreased and therefore, the interval of chemical cleaning for the circulation boiler was extended. 3. Automatic Injection Method of Sodium Phosphate for Heat Recovery Steam Generator (HRSG) of Combined Cycle Power Plant We changed the injection method of sodium phosphate from the semi automatic to automatic injection method which was controlled with the conductivity of the boiler water. In six HRSG of the combined cycle power plant, we automatically controlled phosphoric acid concentration to within the target value. (author)

    Technologies whose names are prefixed with super are discussed from a viewpoint of history of science and technology. A chronology for super-prefixed sciences and technologies in the 20th century is presented. Since Bohr's quantum theory and Einstein's fundamental formula for atomic energy: E = mc[sup 2] that rank as two heads of super-science, were published in the begining of the 20th century, their theories have been playing roles as a foundation of the development of science and technology in this century. Namely, on the basis of quantum theory, semi-conductors were invented and super-conduction has been developed. The Einstein's fundamental formula has led to atomic bombs and commercial power reactors. Development to super-technologies in various fields of sciences and technologies is explained. When a nation's history of science and technology is assumed as a process from mimicry to self-sustenance that is composed of the following four steps: (1) import of products, (2)initiation of production and transfer of technology, (3)transit to technological self-sustain, (4) establishment of creative technology. Japan is in a process between(3) and(4). Further, super-technologies under research and development for the present in Japan are enumerated. 6 refs., 2 figs.

    A survey is conducted of energy-saving and greenhouse gas reducing measures in cooperation with the National Petrochemical Public Company Limited (NPC), Thailand. The NPC is the first petrochemical producer in that country and, after 10 years' operation, the largest such producer there. Transfer of energy-saving technologies from Japan will lead to the construction of clean development mechanism (CDM) in the future. The NPC plant surveyed is situated in a Maptaphut industrial complex, and produces ethylene propylene from natural gas and at the same time serves as a utility center to supply electricity and steam to factories and plants in the vicinity. Items examined involve waste heat power generation, power generating gas turbine efficiency improvement, ethylene plant cracking furnace heat retaining capability enhancement, steam pipe heat retaining material renewal, and replacement of obsolete air conditioners with higher-efficiency equipment. After tentative calculation a conclusion is reached that the total of energy-saving effects of the said five items will be 21,900 tons/year in terms of crude oil and that a CO2 reduction will be feasible at a rate of 45,300 tons/year. These figures are larger than the ones predicted before the survey. A total of 354.3 million bahts will have to be invested. Negotiations will continue with attention directed to the progress of NPC's preparedness to accept CDM. (NEDO)

    Processes that contain latent environmental problems are the massive generation of wastes (inorganic salt, acid catalyst, base catalyst, and huge quantities of wastewater), handling of dangerous substances (use of hydrogen fluoride, use of phosgene, and use of substances whose discharge is legally controlled), processes which consume much energy (circulation of quantities of raw materials, use of quantities of solvents, separation of products with difficulties, use of high pressure, and multiple stage reaction), and processes which are expected to use resources now remaining unexploited. As an element technology for the solution of problems, there is the development of a solid redox catalyst for liquid phase oxidation. As compared with a liquid phase homogeneous catalyst, it discharges less inorganic wastes, facilitates the separation, recovery, and treatment of inorganic salts, corrodes structural materials less, and is thermally stable. An alkane partial oxidation catalyst when developed will achieve more energy conservation than an alkene oxidation catalyst. In relation to acid/base reaction, the zeolite catalyst will be improved and ultrastrong acids and ultrastrong bases will be developed, and these will reduce wastes, mitigate corrosion, and facilitate product separation. The development of a process is also expected which will avoid the use of toxic phosgene. (NEDO)

    For the purpose of developing a rotational seismograph capable of measuring the rotational component of seismic waves, vibratory gyroscopes were installed in the ground for the measurement of vibration of the ground, and the measurements were compared with the values obtained from tests using conventional velocity type seismographs. In the experiment, the plank was hammered on the east side and west side. The seismographs were arranged in two ways: one wherein they were installed at 7 spots at intervals of 1m toward the south beginning at a position 3m south of the vibration source with their rotation axes oriented vertical, with velocity type seismographs provided at the same spots; and the other wherein three rotational seismographs were installed 3m south of the vibration source with their rotation axes respectively oriented vertical, in the direction of N-S, and in the direction of E-W, with a velocity type seismograph provided at the same spot. It was found as the result that the rotational seismograph has a flat band on the lower frequency side and that it may be applied to elastic wave observation across a wide band. Accordingly, it is expected that it will be applied to exploration that uses the SH wave, to structural assessment that uses the Love wave, and to collecting knowledge about the features of natural earthquakes. 2 refs., 8 figs.

    In February 1997, Toyota entered the marine business, a new business sector for it, by marketing a 28-foot cabin cruiser PONAM-28, developed by utilizing its automotive technologies. When Toyota began studying the possibility of entering the marine vessel industry in 1990, its main focus was on the environment. Therefore, in terms of materials procurement for the designs, Toyota refrained from using thermosetting resins, as much as possible. Instead, the decision was made to use an easily recyclable aluminum alloy for the hull which amounts to one-fourth of the vessel's total weight. (author)

    When a part of the ground is replaced with artificial materials in the construction of important structures on soft rock foundations, it is desirable for the artificial materials to have the rigidity equivalent to that of the surrounding ground and to be stable in the long term. The article reports a success in the development and utilization of artificial soft rocks satisfying the above conditions by using a raw material produced locally at the construction site. The soft rock aimed at was mudstone belonging to the Neocene period, and the artificial material of soil-mortal system is selected as the equivalent having the same physical properties. Improvements in selection of solidification agents and cohesive soil were especially contrived: taht is, a new material for solidification was developed by mixing blast-furnace cement and gypsum; and the mudstone on the site was used as the cohesive soil by slurrying it to adjust its grain size to homogeneous composition. The artificial soft rock resulting from the above contrivance showed excellent flow, self-leveling, and filling properties at the stage of fresh mortar, and the physical properties after hardning was very similar to those of the natural ground. The long-term stability was also confirmed by the tests on hydration reaction and environmental factors. 2 figs., 1 tab.

    This paper introduces the Japanese experiment module (JEM) in developing a space station. The JEM consists of systems of a pressurizing section, an exposure section, a pressurizing portion of a supply section, a manipulator and an exposure portion of the supply section. The pressurizing section circulates and controls air so that crews can perform experiments under pressurized environment. The exposure section is a part in which experiments are carried out under exposure environment. The supply section runs between a station and the ground, with required devices loaded on it. The manipulator performs attaching a payload for the exposure section and replaces experimental samples. The JEM undergoes a schedule of fabricating an engineering model, testing for a certification a prototype flight model, and putting the model on a flight. The pressurizing section, exposure section and manipulator are at the stage of system tests. Surveillance of the JEM and control of the experiments are carried out at the Tsukuba Space Center. The Center is composed of a space experiment building, a zero-gravity environment testing building, an astronaut training building, a space station operating building, and a space station testing building. 7 figs., 2 tabs.

    1965-09-01

    Exploration in the Sonai Plain by Sekyu Shigen Kaihatsu Kabushiki Kaisha (Oil Resources Development Corporation) since 1955 is described. The development tasks are made difficult due to the presence of permeability traps. However, 41 out of 65 wells drilled up to late March of 1965 have been successful. Quantities of crude oil and natural gas produced in 1963 were, respectively, 5 and 6 times those of 1958. The Sonai Plain is a relatively new area, and there are still many unknown factors, yet the rate of development has increased greatly. More and deeper wells are expected to be drilled with even better results.

    Petroleum production and its supply and demand require ever closer coordinations among the countries involved. On the other hand, however, there a large number of difficult questions as the problems of global environmental pollution and greenhouse effects increase their seriousness and the economic resources in the petroleum business become scarcer. This paper describes the current state of the Japanese petroleum development, the necessity of spontaneous petroleum development, the international trends in the petroleum development business, and the tasks for Japan in the petroleum development business. Japan is a late comer in the petroleum development business. There are such difficulties as sizes of oil fields being discoverd are becoming smaller, the natural conditions in development target areas are getting severer, and the economic effects are inferior. Japan, whose petroleum self-supply rate is about 0.3%, whose petroleum dependency is heightening as a result of increase in nuclear power generation, and who is the third largest petroleum consuming country next to the U.S.A and Soviet, must use efficiently her financial and technical powers to vitalize her spontaneous petroleum development. Japan has a duty to contribute to the world {prime}s future stabilized supply of oil. The Japanese Government has launched the five-year fund development plan to perform basic surveys for ail in the north-east part of the Japan Sea and the pacific Ocean.

    Since 1987, petrochemical industry has jumped into the era of properity and as a whole, been supported by increasing demands. Although it is said that the 21st Century is the age of chemistry, but for petrochemistry the age of 1990 {prime} s is the age of international competition for the survival towards the 21st Century. The scale of individual enterprise of the Japanese chemical industry including petrochemical enterprises still remains small when compared with that of the individual world-wide chemical enterprises of the U.S.A., Germany and the U.K., etc., besides these world-wide enterprises have established their production bases and research facilities in Japan. In addition, there is somewhat uncertainty in the foundation which is supporting the present prosperity. This article scans the present situation of petrochemistry in its preface, explains the present state and trends of individual industry in the chapters covering the environment around the Japanese petrochemical industry, the report (summary) of the Long Term Credit Bank Institute of Management, trends of advance of oil industry into petrochemical business, production capacity of ethylene and new as well as additional plant construction plans. In this industry, is observed the constitution of Japan which is unable to form internationally competitive power irrespective of her recognition of its necessity because of their giving priority to the balance of their business world. 1 tab.

    For the cleavage of carbon-chlorine connection and decomposition of benzene rings which are hazardous causes of the environmental pollutants represented by dioxins, the photolysis of gaseous phase chlorobenzene used as a model compound was made using KrF and ArF excimer laser. The decomposition is high efficiency, and ArF shorter in wavelength can be compounded twice-four times as fast as KrF. It was found out that in the system where oxygen exists, carbon monoxide, carbon dioxide, acetylene, hydrogen chloride, etc. are produced as decomposition products. From the results of the gaschromatographical analysis, chlorine compounds were detected as solid phase decomposition products. However, by the oxygen existence effect and laser shorter wavelength effect, the formation of polychlorinated aromatics was controlled, and chlorine compounds were made non-pollutant together with the composition. It was indicated that the environmental clean-up technology using laser is effective for making low-concentration environmental pollutants non-pollutant, and it is a method to clean up the environment which has a wide range of the application field.

    The olfactory cell is the most prominent chemical sensor to detect various kinds of external chemical substances with high sensibility. Consequently, on the model of such an organic chemical sensor mechanism, an artificial membrane with functions to detect and distinguish various chemical substances has been developed. In this study, a test using a lipid bimolecular membrane was carried out. As a result, it was found that the lipid bimolecular membrane showed membrane potential changes responding to various odorants. The mambrane with proper lipid composition presented almost the same sensibility to odorants as an olfactory organ. Response characteristic against various odors changed greatly due to the lipid composition and the addition of protein. It was also found that various odors can be discriminated by analyzing response information obtained from a lot of mambranes with different compositions Such ideas can be applied to the odor discrimination of the artificial membrane sensor. 14 refs., 13 figs.

    A method for estimating chemical composition of original fluid before boiling from the composition of whole fluid flowing into a well is described for the case where an aquifer boiling has begun in a reservoir bed associated with discharge of geothermal fluid from the well (the enthalpy of fluid flowing into the well is larger than an enthalpy possessed by a hot fluid-phase saturated by steam at measured temperatures at flowing point). In this case, it is especially pointed out that the gas-liquid ratio at the well flow-in point becomes larger than the one at boiling. The boiling in the reservoir bed is modelled into two types. One is for larger coefficient of permeation in the reservoir bed where the discharge flow at the well is large, the temperature drop around the well is small, and the boiling is in single stage. The other is for smaller coefficient of permeation in the reservoir bed where the discharge flow and temperature drop are contrastive to the former case, and the boiling is in multi-stage. Calculation processes based on this boiling model are explained with calculation examples. 8 refs.,7 figs.

    Tehcnology for separation, recovery and fixation of CO {sub 2} was stated. In an absorption method used as a separating recovery method, CO {sub 2} in the waste gas is absorbed into a solution such as amine, heated and recovered. In an adsorption method, the CO {sub 2} is adsorbed by adsorbent such as zeolite, and recovered either by reduction of pressure or by heating. In a distillation method, the CO {sub 2} is distilled under low temperature and high pressure. In a membrane separation method, the difference of the membrane transmisison speed is used. In a fixation technology, the CO {sub 2} disposed into the ocean is liquefied by compression and forced into the deep sea through pipings. The liquid CO {sub 2} has greater density than water under 200 to 300 atmospheric pressure and clathrate is produced over the interface between the sea water and the liquid CO {sub 2} but the influence on the environment should be evaluated. As a means of recycling, synthesis of methanol or hydrocarbon with hydrogen contacting can be considered, and if such synthesis is used, fossil fuel can be reduced. As the source of the hydrogen, a method for combining the electrolysis of water and energy such as the sun and hydraulic power which do not generate CO {sub 2}. 16 refs., 3 figs.

    An ultrafine iron particle preparing process was developed, which wses gaseous phase pyrolysis in magnetic field of iron pentacarbonyl, Fe(CO){sub 5}, based on the fact that Fe(CO){sub 5} has peculiar characters that its boiling point is as low as 103{degree}C, and starts decomposing in a low temperature zone of 100{degree}C or lower. Vaporizing and introducing into a reactor an fe(CO){sub 5}, andPyrolyzing it at 200-600{degree}C while being diluted with nitrogen and applied with a magnetic field produced uitrafine iron particles of a necklace-like chain comprisinh primary particles having diameter of 15 to 25 nm with 10 to 40 of them linked in a straight chain. It was found that the specific surface area is 30-50 m{sup 2}/g, with the diameter converted from the specific surface area being relatively close to the average diameter obtained from TEM photograph, and that the particle has few pores. Magnetically the iron powder has a coercivity of 123-131 KA/m and a specific saturation magnetization of 120-140 Am{sup 2}/kg, and is expected to be applied as a high density magnetic recording medium. 5 refs.,8 figs., 3 tabs.

    A questionnaire investigation about the present situation, current problems and countermeasure to be discussed with by material technology groups in the eight chemical companies was carried out. It has become clear from the analysis of answers obtained that the roll of material group has been changing under the diminishing construction of new plant and the increased needs of stable and sustainable plant operation. The present major subjects of material groups, which are pointed out in the answers, are such new technological problems as the plant life estimation, the dissemination and handing down of material technology and the upbringing of technology successors. The countermeasures to meet those requirements made clear are such technology developments as a new monitoring system, preparation of database on material technology and closer cooperation with relatied associations. It is hoped for that the findings of this study would lead to further and more detailed indentification of common problems to be solved and development of practical countermeasures therefor.

    The molten salt system electrochemical cycle was proposed to reproduce pure Al from scrap Al. The cycle is composed of production of rough AlCl3 by chlorination of scrap Al, refining of rough AlCl3 mainly by sublimation, and electrolytic reproduction of pure Al from refined AlCl3. In production of AlCl3, the Al-Cl2 molten salt system cell composed of anode dissolution reaction of Al and cathode reduction reaction of chlorine gas can generate electric power for the electrolytic reproduction. Chlorine gas can be recycled as anode product. Various experiments were carried out to improve molten salt system cells. In analysis of cell output, voltage drop from open circuit voltage was divided into that due to electrolytic bath resistance, and that due to reaction resistance. The electrolytic bath resistance could be determined from transient characteristics of voltage change just after cutoff of output current. The product of the obtained reaction resistance and a meniscus length was constant regardless of a meniscus length, and useful to predict scale-up cell performance. Output characteristics dependent on meniscus position were also obtained. 16 refs., 11 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.

    To reduce the construction period and cost and to enhance the safety during 77 kV-class transmission tower election, a new method of small steel transmission tower erection using an external type crane has been developed. For the selection of cranes, a commercially available self-climbing crane was employed which has an operating radius of 11 m, a lifting load capacity of 1.5 t, and a lift of up to 60 m. For the space analysis using a model tower, various supporting methods with horizontal supporting members, stress analysis for each tower stub, and apparatuses were examined. For the demonstration tests of election using the model tower, strain gages were attached at each point of steel tower, crane and horizontal supporting members, to measure the stress of members at each stage of the election. It was confirmed that there were no problems. For the election of actual steel tower, the practicality of this method was compared with that of conventional methods. The construction period was reduced in 20%, and the cost was reduced in 4%. The safety of this method was drastically enhanced due to the lack of moving on the tower and less manual operation. 9 figs., 1 tab.

    Efforts were exerted in fiscal 1984-1992 to develop techniques for appropriately assessing a geothermal reservoir for its productivity for duly predicting the optimum scale of power generation to be provided thereby. In the development of simulators, geothermal reservoir simulators (SING-1, -2, -3) and a geothermal well 2-phase flow simulator (WENG) were developed. As for the treatment of fractures in a reservoir and of substances soluble in the hot water, the methods for dealing with them were improved and augmented. In a model field study in a Hokkaido forest, reservoir pressure continuous observation and monitoring, temperature logging and pressure logging for existing wells, and geothermal fluid chemical analysis were performed for reservoir analysis, in which both natural state simulation and history mapping excellently reproduced the temperature and pressure distributions. The temperature and pressure distributions in a natural state simulation, out of the results of an analysis of the Oguni district model field, Kumamoto Prefecture, agreed not only with those in the natural state but also with the pressure transition data in the observation well.

    With regard to the Ashiro Town area in Iwate Prefecture, this paper reports the result of evaluations based on temperature and pressure logging after a lapse of an extended period of time (well No.2) and a steam jet test (well No.1). These activities were performed as the survey on promotion of geothermal development and survey on development feasibility in fiscal 1997. As a result of the overall analysis based on the present survey and ones in the past, the geothermal system model in the surveyed area may be conceived as follows: in both of the N7-AR-1 and N7-AR-2 wells drilled in the southern part of the surveyed area, temperature as high as 250 degrees C or higher was confirmed; the underground temperature is 200 degrees C or higher at an altitude level of zero meter and 250 degrees C at around -500 m, leading to a belief that the high temperature area spreads to south; as a fracture system holding geothermal fluid, a fault was identified at the N7-AR-1 well drilling depth of 1710 m; in the steam jet test, a geothermal reservoir (a shallow geothermal reservoir) was confirmed to exist; the geothermal fluid that has jetted out shows alkaline Na-SO{sub 4} type; and the deep geothermal reservoir has high temperature and is presumed to be in the two-phase condition, presenting promising factors as the geothermal resources.

    As to long-term energy technology strategy, the paper described the results of the FY 1999 survey of chemical/process technology. The future chemical technology should be transformed from the material production technology in which priority used to be given to convenience to new chemical technology in which the functions needed are to be created. The shortage of the developmental period and minimization of the waste are also desired by the use of new methods. For it, the industry/government/university should gather wisdom together and fulfil the requests from other industries of the country under the circumstances of the society which is aging, is decreasing in birthrate, and is being highly information-oriented. At the same time, the technology should be contributional to constructing the circulating type society which has environmental harmony. If not, it cannot be the technology which is recognized by the society. Efforts should be made for the fundamental technology development, technology to create the materials needed in the society, and development of new process technology to be recognized in the society. Further, the development of technology to meet the needs/restraints from the society should be promoted as seen in the environmental hormone. At the same time, the intellectual base should be prepared such as arrangement of the technology database for advancing smooth technology development. (NEDO)

    Geothermal resources have been evaluated in the Copahue district. For this survey administrated by JICA, drilling of a deep test well with a small bore (COP-3) and blowout tests were conducted. This district is located at the east side of the Andes elongated in the N-S direction. Volcanoes with similar active periods and active states are distributed in the N-S direction, which forms a divide with the Pacific Ocean side. The Copahue-Caviahue composite volcano in the surveyed area is located nearly in the central part of the volcanic zone, which forms a special ring topography. Geology of the Copahue district consists of volcanic effusive rocks during the Tertiary and Quaternary periods. There are five prospecting fields with geothermal indications in the surveyed area. From the survey, an area of about 13 km{sup 2} was evaluated as a geothermal resource field. Especially, in the area of about 4 km{sup 2} including COP-1, 2 and 3 wells, the steam predominant type reservoirs were found out. As a result of estimation of the geothermal resource potential by the volumetric method, a highly prospective power generation potential of 30 MW was evaluated in the field where the steam predominant type reservoirs were confirmed by the boring wells. 7 refs., 13 figs., 1 tab.

    For the enforcement of the {rho}a-{rho}u survey method which is a type of high-density electrical survey, a multichannel resistivity measuring instrument has been developed. This instrument, in addition to the above, conducts resistivity tomography and various other kinds of high-density electrical survey. A potential produced by a low frequency rectangular current of 1Hz or lower outputted by the transmitter of this instrument is received and measured by the receiver connected to electrodes positioned at 100 or less locations. The receiver comprises a scanner that automatically switches from electrode to electrode, conditioner that processes signals, and controller. A transmitter of the standard design outputs a maximum voltage of 800V and maximum current of 2A, making a device suitable for probing 50 to several 100m-deep levels. The receiver is operated by a personal computer that the controller is provided with. The newly-developed apparatus succeeded in presenting high-precision images of the result of a {rho}a-{rho}u analysis for an apparent resistivity section and of the underground structure, verifying the high quality of the data collected by this apparatus. 10 refs., 5 figs., 1 tab.

    1996-05-01

    An S-wave portable vibrator to serve as a seismic source has been developed for the purpose of applying the shallow-layer reflection method to the study of the soil ground. The author, et al., who previously developed a P-wave portable vibrator has now developed an S-wave version, considering the advantage of the S-wave over the P-wave in that, for example, the S-wave velocity may be directly compared with the N-value representing ground strength and that the S-wave travels more slowly than the P-wave through sticky soil promising a higher-resolution exploration. The experimentally constructed S-wave vibrator consists of a conventional P-wave vibrator and an L-type wooden base plate combined therewith. Serving as the monitor for vibration is a conventional accelerometer without any modification. The applicability test was carried out at a location where a plank hammering test was once conducted for reflection aided exploration, and the result was compared with that of the plank hammering test. As the result, it was found that after some preliminary treatment the results of the two tests were roughly the same but that both reflected waves were a little sharper in the S-wave vibrator test than in the plank hammering test. 4 refs., 9 figs., 1 tab.

    The superconducting magnet energy storage (SMES) system has a function by which magnetic energy is stored in a superconducting coil without loss and discharged very rapidly into the power line when needed. The fault current limiter has a function by which transport current is passed without impedance and excessive fault current is restricted by generating large impedance in an emergency. These are the functions of new power equipment, which can not be realized by the conventional equipment. In the small-scale SMES project, Toshiba has fabricated 100 kWh-class element coils and 1 kWh/1 MW modules as the first step of practical application for power system control. For the superconducting fault current limiter, Toshiba has developed a 6.6 kV-1 kA class fault current limiter without supplying cooling medium such as helium, and limiting tests of fault current have been successfully conducted. Through the long-term tests of element coils for SMES and the system interconnection tests of module-type SMES, it is expected that the technological development for practical application is accelerated. 4 refs., 7 figs., 3 tabs.

    An electrohydraulic servovalve that uses clear water as a pressure medium (water hydraulic servovalve) is developed. A conventional electrohydraulic servovalve cannot work with this hostile fluid. This paper explains the structure and functions of components, and the relationship between them, as well as development procedure of the water hydraulic servovalve. The basic idea for the development is to support the spool of the valve with hydrostatic bearings and to lead the water from the bearings to the flapper-nozzle system, which, in this valve contains a laminar restriction upstream from the nozzle instead of the turbulent restriction in the conventional flapper-nozzle system. This paper also explains the design procedure of the hydrostatic bearing in the valve and the connection of electromagnetic elements and the fluidic elements. The manufactured water hydraulic servovalves show good characteristics in their smooth motion, endurance and controllability, including dynamic characteristics. 25 refs., 12 figs.

    This paper introduces the polymer dispersed liquid crystal (PDLC) ACT'' sheet, a liquid quartz light modulating film, developed by the Ajinomoto Company in Japan. A mixture of liquid crystal and polymer precursor is sandwiched between polyethylene terephthalate films imparted with transparency conductor made of indium tin oxide (ITO), which is then polymerized by heating or irradiating ultraviolet rays to obtain a PDLC. The film has a thickness as thin as about 0.3 mm, and good processibility. The sheet uses light modulating elements functioning on scatter and permeation of light. Clarification was made on the voltage dependence of cloudiness, total light permeability, straight and parallel light permeability, the response, and the operating voltage. The system consumes small amount of power with a threshold value of about 35V, and is suitable to operate large areas when working on the utility power supply. An incident light having a high diffusion capability when the electric field is turned off exhibits a high clouding function. The system gives an excellent feel of colorlessness and transparency when the electric field is turned on. The performances in heat insulation, infrared reflection capability and noise resistance are expected to be compounded for a functional versatility. 4 refs., 6 figs., 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.

    In order to measure sound absorption performance necessary to develop sound absorption materials, development was made on a device consisting of a small sound box capable of measurement inexpensively and easily, as a measure against the reverberation chamber method. In order to obtain stabilized diffusion sound internally, the sound box has a shape of asymmetric seven-side body in which sides do not face squarely with each other. The box was so sized that a large number of resonant vibration postures can be constituted at the targeted frequency simultaneously in the box. The box has a commercially available cone speaker with good acoustic output characteristics in frequency range of higher than 500 Hz installed on an inner side of the box. The sound source uses a method to derive sound absorption rate from difference of sound pressure levels. In order to eliminate need of averaging treatment by using a multi-point measurement inside the box, a discussion was given to provide an opening on part of the box to place the sound receiving point outside the opening. A square test piece is placed on the floor 0.5 meter or more away from the speaker in the box. As a result of the experiment, it was verified that the sound absorption rate obtained by this device corresponds well with that by the reverberation chamber method. The size of the test piece was also found adequate. 2 refs., 11 figs., 1 tab.

    1999-06-01

    Kuriyama group of the Osaka Industrial Research Institute developed a new air-metallic hydride battery that is chargeable by both electricity and hydrogen gas. The battery uses a hydrogen storage alloy as the negative pole and uses active carbon coated with platinum as the positive pole. Potassium hydroxide aqueous solution is used as the electrolyte, and a space is arranged in the negative pole for contacting and absorbing the hydrogen with a good efficiency. The key point is the development of the hydride for energy storage that can well absorbs the hydrogen gas even it is dampened by the electrolyte. And the pole is prepared by pulverized the particles of rare earth hydrogen storage alloy having the particle size smaller than 150 micron meter, forming a Ni layer for a catalyst to absorb hydrogen, adding fluorinated resin dispersant for the sake of repellency and forming a sheet. In a test running, a half of hydrogen storage capacity is realized by charging for 30 minutes. And, 0.6 V electricity of 10 mA per unit pole area of 1cm{sup 2} is continuously obtained for 17 hours during discharging. While a third electrode is formed by nickel hydroxide, the battery is chargeable and dischargeable as the same as nickel hydrogen battery. Low cost and small size can be expected by a combination of respectively prepared fuel battery with nickel hydrogen battery. (translated by NEDO)

    Okamoto, Y.; Horiguchi, A.; Ishida, K.; Hata, S. [Mazda Motor Corp., Hiroshima (Japan)

    1995-04-20

    As a part of measures to prevent accidents caused by reduced vigilance and drowsiness of drivers, this paper reports the result of experiments that presents effectiveness of a method to give drivers intermittent auditory stimuli as environmental stimulation. It was found that vigilance decline can be reduced by intermittent auditory stimuli under a laboratory condition using a selective reaction time in monotonous selective reaction works as a parameter; and the effective interval in the intermittence is 30 seconds. A driving simulator was used to prove that the vigilance decline reducing effect by the intermittent auditory stimuli has the same level of effect as chewing gums even under the environment composed of driving operation, vehicle motions, and background noise. However, a number of questions remain yet to be discussed, such as the effect when the ratio of sound presentation time and no presentation time was varied. Furthermore, a number of other physical stimuli in addition to auditory stimulation may be assumed that has effective possibility as vigilance decline reducing stimuli, including hot heat and vibration. It was verified, however, that vigilance decline can be reduced by properly varying the environmental stimulation. 6 refs., 15 figs., 1 tab.

    1994-12-01

    Described herein are the results of the FY1994 research program for advanced glazing in which solar energy is efficiently utilized. The peripheral techniques are surveyed for evaluation of characteristics of large-size dimming glass, optimization of film compositions and scaling up. The dimming device, made on a trial basis, attains a target controllable rage of at least 50% for visible light transmittance. The suitable components include WO3 as the electrochromic material producing color under a reducing atmosphere, NiO as the counter electrode producing color under an oxidative atmosphere, and hydrated SbOx as the proton-conducting electrolyte. The test results indicate possibility of the dimming glass stably operable while being irradiated with a quantity of sun ray of around 10 years. The study on scaling up the dimmer glass develops, on a trial basis, a process for producing large-size glass and evaluates its characteristics, where the film parameters are investigated. It also investigates the peripheral techniques for assembling the devices for the large-size glass, and develops useful techniques, such as those for sealants and improved sealing methods. 1 fig., 1 tab.

    1996-10-27

    This paper introduces history of the development of an electric automobile, `Ecovehicle`. It is provided with a high overall energy efficiency compared with an engine vehicle. The Ecovihicle is 1.2m in width, 3.3m in length, 2 seating capacities and 910kg in overall weight with serially connected 56 batteries of each 4V, 40Ah and having the total weight of 269kg. Its travel distance per charging is 130km at a speed of 80 k.p.h. This vehicle is capable of running with an energy of approximately one third as much as that of a light car. In addition, the vehicle is provided with polycrystal solar batteries placed on 0.6m{sup 2} area on the roof and spoiler generating 60W maximum. Assuming the annual duration of sunshine is 1,800 hours, charging is possible for 63kWh annually. Assuming the charging efficiency is 83%, charging is possible about seven times, which is an equivalent of travelling about 1,000km annually. The characteristics for example are the employment of brushless DC motor, use of energy saving switching element IGBT in order to realize a low level of loss in the inverter, in-wheel motor system, and storage of storage batteries in a hollow aluminum frame installed under the floor. 2 refs., 5 figs., 1 tab.

  17. Development and demonstration of optical polarization controller; Hikari henpa seigyo sochi no kaihatsu to jissho

    Kurono, M. [Central Research Institute of Electric Power Industry, Tokyo (Japan)

    1997-04-01

    If fiber transmission light can be controlled in a stabilized polarization state, realization of coherent optical communication is anticipated. In the case of adopting it to OPGW, however, it is necessary to compensate high speed polarization variation caused by lightning strike. But this was difficult in the conventional method. Accordingly, a high speed polarization control method was proposed which uses an electric effect of lithium niobate (LN) crystals. In the study, a polarization control unit was manufactured based on the method proposed and the performance was demonstrated. As a result of measuring output light with input light changed in every state of polarization, the object horizontal polarization component obtained a stabilized light intensity at {+-}0.1dB, and a light intensity of the component slipped out of the horizontal polarization was suppressed under -20dB. To cope with the polarization variation by lightning strike, it is necessary to make the control delay 10{mu}sec or below, and improvement in processing unit, etc. may make it possible since LN crystals respond below 1{mu}sec. High speed control of the infinitely continuing arbitrary polarization variation became possible. 14 refs., 19 figs.

    Next-generation fuel cells under development by Toshiba Corporation are outlined. The molten carbonate fuel cell (MCFC) has become stable in performance, which results from the conversion of the matrix group from the {gamma}-type to {alpha}-type LiAlO2. The cathode material is expected to withstand the elution of electrolyte for 20000 hours. The soft structure separator developed for stack constitution is expected to improve electrical contact and reduce the cost of stack. An appliance has been completed to tentatively produce every element concerned. During an actual operation, the structural soundness of the 2-cell stack was confirmed by thermal load tests. As for the polymer electrolyte fuel cell (PEFC), an interior humidification method has been developed using a porous material for supplying water to the polymer film. The amount of moisture can be controlled, which will enable a larger-area cell. A 1kW-class stack with a world-record-level 1200cm{sup 2} electrode area has been developed, which stack has shown that the target output has been attained. Furthermore, the power generation efficiency of the system including fuel treatment has been examined. 10 figs.

    1997-10-22

    Technology is discussed of detecting structures buried in the ground by use of a forward-looking sensor mounted on the drill head for the avoidance of collision with such structures during application of the flowmole method in urban districts. In this detection system, pulsating radio signals are emitted from a transmission antenna and the received signals are converted into low-frequency signals in a sampling circuit for eventual display on a B-scope. Since the drill head for flowmole technology is as small as approximately 50-60mm in diameter, experiment is conducted to know the detectability of a very small antenna directed at a buried pipe. The basic phase of the experiment using the very small antenna includes a soil-filled tank test and field test. It is then found that the very small antenna is capable of detecting the steel pipe buried 50cm away from the antenna with the antenna directed at the said pipe. In a test wherein a very small antenna is allowed to rotate on the drill propelling shaft, the design simulating a revolving drill head, it is learned that the detecting system under study will identify the direction in which a buried structure exists. 1 ref., 9 figs.

    1992-01-01

    This paper described the researched results of the demonstrator of a turbofan engine for supersonic aircraft (IHI-17). 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.

    1994-05-01

    The present paper explained the turbofan engine GE90 which is being developed by General Electric Co., USA. That engine is to meet the thrust (takeoff thrust) of 300 to 530kN as required for the new-generation wide-fuselage civil transport plane which is being designed for its planned operation in the 1990's. In April, 1991, the world's strongest thrust of 480kN was achieved with engine elements also confirmed through element test. Thereafter, the engine underwent a flying test on board of Boeing 747 to materialize the planned operation in 1995. Made to be 9 in by-pass ratio and about 40 in overall pressure ratio, the GE90 was given the concept that advantage could be secured in both propulsive efficiency and thermal efficiency. That concept could be materialized by the development of composite fan blade technology and energy-efficient technology which were both demonstrated with an unducted fan. In spite of its pressure ratio of 22, the GE90's high pressure compressor demonstrates its polytropic efficiency which is equal to that of the low pressure ratio compressor. 3 refs., 19 figs., 1 tab.

    1994-05-01

    The control unit of gas turbine for the aircraft jet engine use must draw overall performance in compliance with the thrust commanded by the pilot under all flying conditions of the engine. High reliability is required in flight safety. The present paper explains a developed unit of dual redundant FADEC (full authority digital electronic control) and high-density mounting technology for the electronic devices required by the FADEC. The FADEC unit is composed of two hardware systems with their respective microprocessors of the same structure. Each of both systems can solely control the engine, while they are both commanded by a necessary signal for the dual system operation and connected through a digital by-pass which can exchange the input/output data between them. For the operational confirmation of FADEC unit, its control characteristics were inspected by intentionally putting it out of order at the time of engine acceleration/deceleration and other transient operations. The control system could be switched without control characteristics lost of the engine. 9 figs., 2 tabs.

    NONE

    1997-03-01

    The French Government most enthusiastically promotes development of bio-gasoline in renewable energy field. EU makes pressure to remove the French Government`s fiscal advantages for bio-gasoline which only benefit French farmers, and the IEA (International Energy Agency) report also estimates no benefit corresponding to the fiscal support cost. Start of the `Eolien 2005` project is attractive in renewable energy field which aims at construction of wind power generation stations of 250-500MW by 2005. The `Eolien 2005` project is mainly supported by Electricite de France (EDF) who guarantees the purchase of produced electric power at a submitted price. In addition to this subsidy activity, EDF decided to positively tackle renewable energy. On R and D efforts for renewable energy, France belongs to the most poor countries among IEA countries, and in addition, the effort is considerably concentrated onto the study on reduction of production cost for bio-gasoline. There were no changes in this situation in 1996. 7 refs., 5 figs., 31 tabs.

    The Toyota Hybrid System has two power sources which engage depending on driving conditions. An improved efficiency gasoline engine provides the main power to drive the wheels, as in conventional automobiles. Drive power can also be supplied by an electric motor, which derives its electricity from a battery and a Generator. Fuel efficiency is further boosted by other measures, such as automatically cutting the engine when the vehicle is at a stop and regenerating the energy accumulate during deceleration. Compared with conventional vehicles with a 1.5-liter engine running in 10 {center_dot} 15 mode, the CO2 emissions are reduced by half. Moreover, with the use of a motor to reduce engine load during acceleration, HC, CO, and NOx emissions are cut significantly low levels. 13 figs.

These are a roller part, a control part, a remote control part and a CRT part. In this study, we especially investigated the mechanism and performance between tire and roller. We analyzed the amount of side slip with various toe angles. The developed tester is examined under the conditions that is considered in industrial applications. We investigated the influences of toe angle, size of tire, pressure of tire, coefficient of friction between tire and roller, pushing force of tire, revolution velocity of roller, axle load and so on. The validity of the developed RTSST is confirmed under these conditions. It was found that the RTSST can be used in practical use. Some measurement results are presented in the form of parametric plots. And we also compared measurements data between the RTSST and that of flat type using several automobiles. 4 refs., 8 figs., 4 tabs.

    1992-11-10

    Polyurethane thermal insulator in which the usage of CFC-11 is 50% reduced by increasing the percentage of water has been developed for the purpose of reducing polyurethane-foaming CFC-11 used as thermal insulator of refrigerators. In this new water-intensive feedstock system, the overall OH-value in polyol was lowered; the usage of aromatic amines was curtailed; and the amount of sorbits was increased so as to secure adhesiveness at the foaming jig temperature of 35[degree]C. As for the improvement of fluidity, a combination of four kinds of polyols offered viscosity in the same level as in the conventional ones. Thermal conductivity was worsened, but the rate of its drop could be controlled below 3% by some measures such as homogenization of stock materials, choice of a suface-active agent which makes foam bubbles minute, etc. Concerning curing property which has a large effect on productivity, a reaction type amine-based catalyst delaying thickening behaviour at the time of foaming was selected and a gelling promotive tertiary amine-based catalyst which can develop foam curing promptly was combinedly used to reduce curing property from five minutes in the past to four minutes. 2 refs., 6 figs., 14 tabs.

    1997-11-25

    The paper reported on a Tokyo-Nagoya travel test on a practical spread type solar-electric vehicle, Solar-EV. A comparative study was made running the same type gasoline vehicle, GV. The measured power consumption amount of Solar-EV is 57.6 kWh. By converting it into Mcal unit, an energy consumption amount of 49.5 Mcal was obtained. Further, as to GV, the energy consumption amount of 316 Mcal was obtained using the amount of supply of gasoline (mean heating value: 8.4 Mcal/h) of 37.6 l and the fuel consumption of 16.2 km/l. Accordingly, the energy consumption amount of Solar-EV became a sixth of that of GV. In the cost comparison, the cost of Solar-EV was 1,440 yen (power source price: 25 yen/kWh), which is about a third of that of GV, 3760 yen (gasoline unit price: 100 yen/l). Monocrystal Si solar cells, 270W, installed on hood/roof are connected to the main 288V system (the auxiliary 12V system is amorphous Si), and generate power 4.4 kWh during travel. A total power consumption amount of Solar-EV in the total travel (Tokyo-Nagoya) is 79.9 kWh including the auxiliary system, approximately 6% of which was to be supplied from solar cells. 1 ref., 6 figs., 3 tabs.

  19. Development of solar power generator system; Taiyoko netsufukugo hatsuden system no kaihatsu

    Kisara, K; Kumagai, T; Niino, M; Chen, L; Eguchi, K [National Aerospace Laboratory, Tokyo (Japan)

    1997-11-25

    Described herein is a new hybrid solar power generator system, in which solar energy is separated into the light and heat components by a wavelength-selective filter before being directly converted into electric power, the former for the amorphous solar cell (ASC) unit and the latter for the thermoelectric unit. These units complement with each other to enhance overall efficiency. The ASC unit should have a higher efficiency when it works on the light component, because the heat (infrared) component increases cell temperature and decreases its output. For the ASC unit, the effects of the filter have been tested. The thermoelectric unit, generating power by the Seebeck effect, should have a higher efficiency, if heat flux passing through the unit can be increased, because of increased temperature differential, to which voltage produced increases proportionally. For the thermoelectric unit, heat is collected by a parabolic mirror unit from sunbeams received by a heliostat. Characteristics of these units are grasped almost as expected by the tests. 4 refs., 11 figs., 1 tab.

  20. Development of automatic high-concentration boron measurement technique; Konodo hoso jido sokutei gijutsu no kaihatsu

    1997-03-01

    The technology that can automatically measure the boron concentration in boric acid water was developed. A high-concentration boric acid solution must be held at a high temperature to prevent the deposition. Skill and precision ({plus_minus}0.2 to 0.3% for 10 to 2500 ppm as boron concentration, and {plus_minus}2 to 3% for 2500 to 25,000 ppm) are required to analyze the boric acid solution manually. In theory, the boron concentration in a wide range can be measured, and boron has a constant-temperature function. A density hydrometer method that facilitates the treatment and calibration in high precision and at low cost was chosen. The vibration period generated when vibration is given to the solution specimen put in a U-tube is higher as the density is lower. On the basis of this theory, the density of a specimen can be obtained according to the relation with the same data of the known-concentration boric acid water. The high-concentration boric acid water that cannot be measured by the existing boron densitometer can be measured directly. It can also be measured in a low-concentration area. The technique can be used in a laboratory as the simplified method that is replaced by the current manual analysis. The reduction effect of analytical chemical`s waste liquid can also be expected. In the electric power industry, automated equipment is required for high efficiency and labor saving. 13 figs., 3 tabs.

    This paper aims to develop a clean coal production process which excellently removes environmental pollutant, is low-costed, and need no particular systems for distribution of products. The result of the development was described paying attention to column flotation which is a technology to high-efficiently select particulate regions, particulate heavy media cyclone, magnetic separation, and the basic design of the process into which those above were integrated. The two-stage selection process, which is an integration of column flotation and particulate heavy media cyclone into the conventional coal preparation equipment, can produce low-ash clean coal at high separation efficiency and also suppress the rise in processing cost. This process was also effective for removal of sulfur content and trace metal elements. The use of clean coal at power plant can be effective for not only the reduction in ash treatment amount, but the aspect of boiler operation characteristics such as heat transfer efficiency of boiler furnace wall, ash related troubles, loads of electrostatic precipitator, loads of flue gas desulfurization facilities. 17 figs., 5 tabs.

    The coal partial combustor (CPC) uses a combustion technology with which coal is burned at elevated temperatures and under revolution, the constituents are captured on the furnace wall and removed as molten slag from the furnace. This is a combustion technology to reduce load of ash on subsequent devices. To generate a molten condition, it is necessary to raise the combustion temperature as high as possible (to about 1600 degC in the furnace), but this is effective for a gas turbine composite power generation system. An efficiency of higher than 45% may be expected at the power transmission terminal. As an operation on subsidy from the Agency of Natural Resources and Energy, the normal-pressure CPC technology has already been established, and a research on pressurized CPC is being progressed since fiscal 1991. The research is in progress with a schedule that elemental tests for 7 tons per day production are conducted until fiscal 1995, a 25 tons per day pilot plant will be completed by November 1997, and verification tests for long-term continuous operation will be implemented until 1998. The 7 tons per day elemental tests have identified gasification performance and slag extraction performance using five types of coal having different properties. 7 refs., 10 figs., 4 tabs.

    In steelmaking plants, the relining work of converters requires plenty of manpower and time. Recently, the number of expert brick workers has decreased, and it has been difficult to get together the necessary number of workers for the converter relining. To solve these problems, a robot system has been developed and realized for the converter relining. The system consists of two intelligent robots and an automatic brick conveying machine. With visual function and flexibly controlled hands, the robot enables to heap up bricks in the same manner as expert workers do. The automatic brick conveying machine consists of roller conveyers and a cage lifter that convey bricks on palettes to the suitable position for the robot to easily handle. This robot system has enabled to save much labor for the converter relining. 8 figs.

    A downhole seismic source which can output continuous waves having arbitrary waveforms was developed. The development was targeted to make tomographic exploration purposed to evaluate geological properties of a ground bed before and after constructing a building in a ground several hundred meters deep from the ground surface. The source is considered to be used in an environment consisting of soft rocks or more robust rocks and having no casing. It can be used in a well hole having a diameter of 100 mm, is capable of measuring P and S waves in a distance between well holes of up to 100 m, can be used at a depth of up to 500 m, and can output waveforms having seismic source spectra of up to 1000 Hz. An oscillation actuator using laminated piezo-electric elements was used for the oscillation element. The seismic source consists of a hydraulic device to clamp the equipment onto hole walls, piezo-electric elements as the oscillation element, and an inertia weight for applying vibration from above and below. To make an oscillation, the main body is first clamped on the hole wall. For horizontal oscillation, the piezo-electric elements contained in a clamping device provide the horizontal oscillation. For vertical oscillation, the piezo-electric elements placed below the main body oscillates the inertia weight. The initially targeted specifications have been achieved. 3 refs., 4 figs., 1 tab.

    1997-03-01

    A phenomenon of excess heat generation through the electrolysis of heavy water using palladium metals as electrode can be recognized as new hydrogen energy. Its mechanism has been investigated for four years since FY 1993. In FY 1993, the New Hydrogen Energy Demonstration Research Center and the New Hydrogen Energy Demonstration Laboratory were organized, and the research was initiated. For the excess heat generation demonstration model tests, two types of electrolysis experimental units were constructed, and the Pd/D-based electrolysis experiments were initiated. For the measurements of excess heat using an open type electrolysis cell, there were rather large errors ranging from -13% to +7%. It is necessary to improve the accuracy. For the measurements using a fuel cell type electrolysis cell, generation of the excess heat ranging from 0% to 6% was observed. For the validity of this, it is required to confirm the long-term stability of calibration and cell components. For the correlation between the increase in absorbing rate and the generation of excess heat, results of 2 to 3% lower were obtained. 28 refs., 89 figs., 26 tabs.

    Technological development has been made on excavation of geothermal wells, which are dense, hard, and high in temperature and pressure, in developing geothermal resources in great depths. This paper summarizes the achievements in fiscal 1999. This fiscal year has performed the excavation test using an actual well to verify the reliability in practical use of the developed heat-resistant and durable bit. The test was executed by using a bit with a diameter of 8-1/2 inches in a ground bet having a maximum temperature of 300 degrees C in the Yamakawa geothermal field. As a result, good site evaluation was obtained that the wear and tear after lift-up showed no problems, and sufficient performance was verified in the drilling rate and durability. In addition, the low specific gravity cement for high temperature use that has been newly developed was given a cement mixing test to identify its workability at site and hardening properties, at a test well with a temperature of about 40 degrees C in the Okiri geothermal field. The actual well test was performed in a large-scale lost water occurred in a return well during an excavation by Nittestu-Kagoshima Geothermal Company. Effects were recognized in measures to prevent water loss. (NEDO)

    For the construction works of underground tunnels, mainly the shield method has so far been adopted, but in order to make underground junction of shield machines, the method of utilizing a shaft or the method of improving the earth by the auxiliary methods such as chemical feeding have been adopted. However, either method has restriction for its practical application. The MSD method uses no auxiliary method at all, can join directly two shield machines mechanically underground, has high water stoppability at its junction, is applicable for either of shield machines of slush type or mud pressure type, and is the method to solve totally various problems in the existing joining methods. This method is the one that two shield machines, one on the out-pushing side and another on the in-receiving side, progress from both sides and face each other, then the both are joined mechanically for unification by pushing a steel penetration ring built-in the out-pushing shield machine to the rubber ring built-in the penetration chamber of the in-receiving shield machine. After joining, the shield machines are disassembled for removal leaving the junction only, and the secondary lining is done with concrete. 6 figs.

    A downsized wireless blasting system has been developed for tunnel construction in the mountainous districts. This system consists of an oscillator, loop antenna, and initiator. The ac magnetic field is generated in the loop antenna using 550 Hz ac generated by the oscillator, to induce the electro motive force between both ends of receiver coil in the initiator. It is stored in the capacitor after rectification, to initiate the detonator by discharging with the firing signal. This system has been developed by downsizing the conventional RCB (remote controlled blasting system) for underwater blasting, and unmanned operation is planned in future. An oscillation frequency, 550 Hz with an actual result has been adopted. The arm length of loop antenna is 3 m, which can be installed in the tunnel. Various receiver initiators were fabricated as a trial. A convex type was adopted due to its excellent receiving performance. The receiving performance was improved by increasing the magnetic induction and decreasing the power loss. After receiving voltage of the receiver initiator was confirmed, field initiation tests were conducted. Initiating and blasting were successfully carried out. 5 refs., 15 figs., 3 tabs.

    A light-weight downsized and high efficiency transformer-less type 4 kW power conditioner (inverter) has been developed. This power conditioner insures the system interconnection protection by monitoring the voltage of two single-phase three-line circuits. The power conditioner has weight of 17.5 kg and efficiency of 94%. Potential fluctuation of photovoltaic cells due to the switching of power devices at the inverter was reduced. Output capacity was reduced in the low input voltage range. Outflow of DC component was prevented in high accuracy by usually correcting the zero point drift of detector, and by using the current detector with excellent linearity. To detect the DC ground fault, and to trip the output side breaker locating at the ground fault current pass, a zero phase converter detection circuit has been developed, by which the DC component can be detected at the DC input side. As a result of performance verification, the efficiency, power factor, EMI level, protection of outflow of DC component, protection of ground fault, protection of single operation detection, and noise level were satisfied. This system is prospective for the diffusion of photovoltaic power generation in the future. 3 refs., 8 figs., 1 tab.

    This report relates to the designing of functional materials that decompose in response to various signals. A derivative of {alpha}-bromomethylstyrene is caused to act on the living anions of {alpha}-methylstyrene for the synthesis of a pyrolytic polymer having unsaturated groups at its terminals. The terminal double combinations of this polymer split under the influence of heat, acid, or base for depolymerization which is quantative, and the decomposition temperature may be controlled by replacing terminal phenylallylic groups with methyl groups or phloro-groups. Furthermore, a novel polythyramine polymer is synthesized with its principal chain constituted of NCH2CH2Si, the principal chain easy to disintegrate when exposed to an electron beam. The polymer is signal-responsive and may be patterned by use of an electron beam. As a temperature-responsive polymer with the hydrolytic feature controlled, poly(thyroxy ethylene glycol) is obtained from a derivative of diaminosiloxane and oligo-oxyethylene. This is a high-mobility, temperature-responsive material whose hydrolysis may be controlled. 3 refs., 2 figs.

    Feeding experiments were conducted to examine the potential use of defatted soybean meal (SBM) in combinations with blood meal (BM), corn gluten meal (CGM) and freeze dried meat of blue mussel (BMM) as a partial replacement of fish meal (FM) in the diet of Japanese flounder. Availability of CGM in combinations with BM and/or BMM was also examined. Juvenile fish of about 4 g in initial body weight were fed diets to satiation twice daily, 6 days per week for 8 weeks at 20 degree C in both feeding experiments. Weight gain of fish fed diet replacing 45% FM protein with SBM was not different from that of fish fed the control diet containing FM as a protein source, however, feed efficiency (FE) in fish fed the SBM diet was significantly lower. Growth and feed performance of fish fed diet replacing 45% FM protein with SBM and BM were comparable to those of fish the control diet. Inclusion of 5% BMM for equal amount of SBM in the SBM-BM diet improved the growth and FE of the flounder remarkably and both values were significantly higher than those in the control. Replacing 55% of FM protein with SBM and CGM or SBM and BM resulted in poor growth performance. There were not marked differences in hematological characteristics together with proximate composition of the whole body of cultured fish fed the dietary treatments. Weight gain and FE of fish fed diet replacing 40% FM protein with CGM were inferior to those of fish fed the control diet containing FM as a protein source. Replacement of 40% FM protein with CGM and BM made those parameters worse. Inclusion of BMM in CGM-BM diet did not improve the growth of fish. Adverse effects of replacing FM protein with CGM and/or CGM and BM were stronger with increasing replacement level. These results indicate that SBM is highly available as alternative protein source for fish meal in the diet of Japanese flounder. SBM in combination with BM successfully replace about 45% of FM protein in the diet without supplemental amino acids. Furthermore, it is suggested that more replacement can be attained with inclusion of 5% BMM in the SBM diet. CGM is not considered to be useful ingredient on practical bases. (author)

    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)

    Concerning a project whose aim is to develop heat resistant engine members through the application of the concept of functionally inclined materials, deliberation and assessment are made of the meaning of its implementation, validity of the research program, research achievement, etc. The project deals with a specimen, diameter 150mm or more and thickness 5mm or more, built of a zirconia/stainless steel-based functionally inclined material, and its goal is to develop technologies for optimizing the baking process for the said specimen, baking system and related devices, assessment technique, tribological assessment technique, etc., and it is inferred that these targets are reasonable. As the result of this research, an energy-efficient (power consumption reduced to 1/3 to 1/5) practical rapid sintering system is constructed. Basic data are collected relative to the tribology of the functionally inclined material, and it is proved that it is feasible to use the material for engine members. The process technology, assessment technology, and devices developed under this project are the first in the world, and are highly evaluated. (NEDO)

    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.

    Matokawa, Y. [Institute of the Space and Astronautical Science, Tokyo (Japan)

    1998-05-01

    Space development has an aspect of contributing to livelihoods. Various types of satellites, such as those for weather forecasting, TV broadcasting, international communication (telephone and internet systems), and GPS-aided car navigation, have been already launched. Space science of the 20th century roughly tells the history of some 15 billion years from the big bang to birth of mankind as a spectacular story. The international space station, construction of which is to be started in 1998, should drastically enlarge man`s experiences in the universe. The space activity plans for the future draw various dreams, such as spaceplane, lunar base, solar generator satellite, Mars base, space colony, skyhook, and so on. Dreams of mankind have been eventually realized in the past history. It is time to deliberately assess what are meant by the space development of the 20th century, and to review ideal directions of the space development for the next 100 or 1000 years. 6 figs.

  7. Development of ultra-low pressure reverse osmosis membranes; Choteiatsu gyakushintomaku no kaihatsu

    Hirose, M.; Ito, H.; Ohara, T. [Nitto Denko Corp., Osaka (Japan)

    1998-06-05

    Described herein is development of ultra-low pressure reverse osmosis (RO) membranes. The composite RO membrane, which is now widely used, has a cross-sectional structure consisting of an ultrafilter membrane as the support and a very thin skin layer responsible for filtration. It is confirmed that the skin layer is of a pleated structure. Growing this structure can greatly accelerate permeation of water without damaging arresting and durability characteristics of the membrane, and hence is a desired approach. Utilization of molecular structure simulation of the skin layer materials is investigated by the molecular dynamics. The results show that the stable structure of the material for the skin layer in the RO membrane is a network structure with regularly arranged honeycombs, when it should arrest at least 99% of salt. These techniques serve as the bases for development of the ultra-low pressure RO membranes (ES Series), where the skin layer is made of cross-linked, totally aromatic polyamide. The membrane passes twice as large a quantity of water as the conventional one, is highly resistant to chemicals, and arrests 99.7% of salt. 3 refs., 4 figs.

  9. Development of lowdrag aerodynamically stable with indented processing; Indento kako wo hodokoshita seishin keburu no kaihatsu

    Hojo, T.; Yamazaki, S.; Okada, H.

    1998-10-29

    A wind-resistant design of cables for large cable-stayed bridges is required as a measure against rain-wind induced vibration. In such bridges, many cables are arranged in a short pitch, which causes a large drag force on the cables. Therefore, reduction of drag force on cables is essential for rationalizing bridge design, as well as restraint of vibration. This paper describes studies on a new cable having both a low drag co-efficient force and rain-vibration suppressing effects. Through many investigations using wind tunnel tests, an indented cable was developed as a countermeasure against rain-wind induced vibration, and finally it was applied to the Tatara Bridge which is the largest cable-stayed bridge in the world.

    1996-10-15

    Outlined herein is technical development of long-spanned bridges represented by suspension and cable-stayed bridges. The design of long-spanned bridges requires theoretical analysis of flexibility in which balance after they are deformed by load is taken into consideration. The matrix finite displacement analysis program is developed for optimizing cable-stayed bridge designs and determining suspension bridge shapes as the new major functions. The analysis program, named KASTAN, is also developed for stress analysis of the structure details. A wind tunnel for structure designs is installed to analyze resistance to wind. A number of experiments have been carried out by the tunnel for the designs of segment, main tower and overall bridge models. The means of controlling wind-caused vibration include hydraulic dampers, mass dampers, and combination of high damping rubber and spacer. Cable-stayed bridges are highly flexible, their types being selected by tower height and shape, span ratio and shape of the main beam, and cable position. These bridges constructed by the company include the S-shaped ones whose main beams are supported by cables suspended by two towers of different height, and the others with H-shape towers of high columns which are connected to each other by horizontal beams. 11 refs., 15 figs.

    For the establishment of a practical process for substitute natural gas (SNG) production, technological and economical assessments were made, and tasks to discharge for the development were discussed. In this fiscal year, the results of surveys conducted in the past five-year period were compiled, and studies were made to prepare for a smooth transition to the element research stage. Findings obtained are described below. SNG producing technologies need to be developed, with the demand for SNG increasing sharply, to further stabilize the base for SNG supply; coal which is abundantly available should be used as the material for SNG; and coal hydrogasification, among various methods for producing SNG from coal, is the most suitable in view of efficiency and cost performance. It was also found after a prolonged study for the improvement of efficiency and cost performance that probabilities were high that the yield of BTX (benzene, toluene, xylene) would increase and cost performance would improve. Besides, a basic plan and an element technology research plan were prepared for the development of the ARCH (advanced rapid coal hydrogasification) process. (NEDO)

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. These achievements lead to a belief that the targets for the present research and development have been achieved. (NEDO)

    This study is aimed at studying for survey of gas hydrate (GH) deposit required for GH resource development and gathering of it, and further at studying for industrial utilization technology development of GH which is different in formation condition depending on kind of gas with which it reacts. The results of FY 1998 are as follows. In the study of the situation of existence of gas hydrate in the tundra, the sedimentary environment of the tundra where natural gas hydrate exists was simulated in laboratory to measure thermal conductivity of the sediments including GH. In this fiscal year, design/fabrication/calibration were conducted of the GH synthesizer and thermal analyzer. In the study of GH gathering technology in the tundra, a technology is discussed for recovering gas from GH layer and at the same time substituting CO2 hydrate for GH by blowing CO2 into the geologic layer. In FY 1998, formation/dissociation behaviors were first studied of methane/CO2 mixture hydrate. For the overall energy development of GH resource and promotion of R and D of the utilization technology, studies were made on physical properties of GH and development of the usage. (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)

    To gain a helpful guide toward the next process by properly evaluating the current project, evaluation of cost and inputted energy is indispensable. In fiscal 1981, as the first step of such evaluation effort, a manufacturing process model is built based on data about designing and manufacturing, and is subjected to analysis. Cost forming factors are extracted from the respective processes, and their relations are analyzed. Parameters are analyzed for the survey of energy that a system demands for operation. Test facilities now under construction are also subjected to a cost analysis. A system design document is prepared for cost analysis and for assisting the process improvement and evaluation work. For the establishment of low-cost mass-production technologies, it is necessary to reappraise the currently-employed technologies for all the processes. It is necessary to coordinate the basic processes in terms of dimension and efficiency to enable them to function as a continuous, consistent production process. Target values are set for the respective processes for an output of 500kW/year at a cell conversion efficiency of 9%. In selecting items to be specified and values to be attained, users' requests are fully considered. Details are prudently coordinated of conditions for delivery from a process to another. (NEDO)

    Introduction of a number of robots and consumption of a large amount of energy are unavoidable if a complicated process operation is to be carried out by robots in an extensive work site. Great energy conservation is contrived by developing robots applicable to manufacturing in performing a variety of operations in place of human beings and thereby reducing the number of robots to work. This paper explains the fiscal 2000 results. For dual-handed cooperative tasks, a function was examined capable of gripping an object without giving a humanoid robot an instruction of an exact gripping position. A method was designed to prepare a command for the other arm through a command for one arm, with torque impedance control employed for the purpose of avoiding damage due to collision. A study was conducted on a three-dimensional shape detecting model using a visual device of a robot. In grasping problems of balance control of a humanoid robot, the behavior of a robot consisting of multi-links was considered as behavior of inverted pendulum, with possibility checked for the stabilization of the balance. For the purpose of putting the virtual robot platform previously developed to practical use, a three-dimensional operation tool of run-time user interface was developed, with research conducted on the sophistication of robot application.

    The dye finishing operation in the textile industry places heavy load on the global environment. This paper describes the achievements in fiscal 1998 on development of process to eliminate the load. Low-temperature plasma treatment was introduced into the desizing and refining process to develop a continuous treatment process using no water and chemicals. Quality equivalent to that produced by conventional methods was obtained by applying an appropriate plasma treatment condition. The energy saving rate was presented by reduction by 84.3% converted into steam. Conventional dye finishing operation uses three to six times as much water as the cloth weight. The developed air flow treatment device reduced the water ratio to less than one. This is 86.0% reduction of energy consumption converted to steam. In removing pectic substance in cotton refining, no water, chemicals and steam were used, but were substituted by enzyme for continuous treatment. Good finishing result was obtained by performing bleaching and dying. Enzyme cost is an issue, but the cost would decrease if it is used in large quantity. A two-dimensional colorimeter (measures cloth color with high clarity and reproducibility) and an automatic dye preparing device (with high volume measuring performance) were developed. If the cost required for re-coloring under the present inspection method is converted into energy, it corresponds to 81.6% reduction. (NEDO)

Few data are available for environmental resistance of composite materials, whereas identification of environmental deterioration behavior and establishment of a environmental resistance evaluating technology are a significant issue in utilizing these materials as new materials for space, aeronautics, and marine applications in the future. The present research was taken up with objectives to elucidate deterioration behavior of composite materials exposed to special environment in the atmosphere and space and to establish methods for acceleration tests and environmental performance evaluation by using simulated environments equivalent to the natural environment exposure. The former period (fiscal 1982 through 1984) has investigated environmental conditions in the atmosphere and space, prepared standard test specimens, performed design on environmental devices simulating the environmental elements, as well as tests on deterioration due to environmental elements, and systematized the deterioration characteristics to establish composite test conditions.

    With the purpose of developing high strength alloys through grain refinement, R and D was conducted, with fiscal 2000 results compiled. This year, using hot rolled plates and cold rolled plates of 5083 based alloys, research was carried out on an optimum warm processing method for forming microstructures. When 5083 alloys were rolled with a large reduction by one pass under a warm to hot temperature range, recrystallized grain structures were obtained having 3-4 {mu}m in the surface and 7-8 {mu}m in the center. The proof stress of these specimens was about 1.3 times as strong as an ordinary 5083 alloy soft material while the elongation was about the same. In the case of 7475 based alloys with Zr added in place of Cr, a warm rolling method, in which the alloys were heated to 350 degrees C and repeatedly reheated by one pass at that temperature, was found effective in forming micro-subgrain structures. By the warm rolling method in which roll temperature was suitably heated, it was made possible to steadily form thermally stable microstructures in 7475 based alloys. The 7475 based alloy plate having a microstructure is superior to an ordinary 7574 plate in resistance against stress corrosion cracking. (NEDO)

    The research and development aims to establish, through verification tests, practical application technologies for two methods, namely, a 'low-temperature liquid phase method' by which cost will be reduced thanks to simplified plant facilities and a 'vapor phase fluidized bed method' in which a composite reforming process may be combined for better economics of scale with a vapor phase fluidized methanol synthesizing method whose facilities may be built to be very large. For the former method, development efforts are made to enable catalyst performance characterization and low-temperature liquid phase methanol production using a small pyrolysis reactor. In the research on pyrolysis reaction, a Raney copper/KOMe/MeOH-based catalyst is used, and this attains a raw material gas conversion efficiency of 92.7%. In the construction of a low temperature liquid phase process, it is found that a single spun conversion efficiency of not less than 90% may be achieved using a heterogeneous catalyst.

    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)

    HFC-23 is produced as a by-product during HCFC-22 manufacturing (produced at by-production rate of about 2%, whereas the reaction control has limitation in reducing the production). This is one of the substances subjected to the greenhouse effect gas reduction in the climate change framework treaty. This paper describes the achievements in 1998 on developing the HFC-23 destruction technology. High-temperature pyrolysis decomposes the substance into HF and CO2, which are given absorption treatment by water and alkali to make them harmless, and are recovered finally as calcium fluoride. An equipment having the treatment capability of 195 kg/h was constructed. Design was made on a facility capable of treating fluorine containing waste water at 3 t/h at maximum. Utilities consumed in a factory (industrial water, acids for neutralization, and alkali) are used effectively to identify the effect of reducing the treatment cost. Discussions were given from the safety aspect on facilities to prevent leakage of fluorine containing waste water being a harmful substance. Fabrication was executed on a full-size treatment testing equipment that can utilize the utilities in the factory effectively, and trial equipment operation was performed to arrange the system prepared toward the future tests and researches.

    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 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. It was not adequate, therefore, to advance the next R and D phase as planned, and decided that the project was suspended to see the world development trends, because the clear plans for the future could not be drawn at that time.

    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)

    To gain a helpful guide toward the next process by properly evaluating the current project, evaluation of cost and inputted energy is indispensable. In fiscal 1981, as the first step of such evaluation effort, a manufacturing process model is built based on data about designing and manufacturing, and is subjected to analysis. Cost forming factors are extracted from the respective processes, and their relations are analyzed. Parameters are analyzed for the survey of energy that a system demands for operation. Test facilities now under construction are also subjected to a cost analysis. A system design document is prepared for cost analysis and for assisting the process improvement and evaluation work. For the establishment of low-cost mass-production technologies, it is necessary to reappraise the currently-employed technologies for all the processes. It is necessary to coordinate the basic processes in terms of dimension and efficiency to enable them to function as a continuous, consistent production process. Target values are set for the respective processes for an output of 500kW/year at a cell conversion efficiency of 9%. In selecting items to be specified and values to be attained, users' requests are fully considered. Details are prudently coordinated of conditions for delivery from a process to another. (NEDO)

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.

    Research, development and evaluation were performed with an objective of establishing the basic technology related to ultra-grid elements. With regard to the process technology to search materials suitable for the targets of ultra-grid elements and manufacture ultra-grid element structure, a technology has been completed, by which crystalline growth is performed while controlling AlAs and GaAs at atom layer levels by using the MBE process and MOCVD process. This has allowed the understanding to be progressed on behavior of electrons in hetero interface or very thin films. It has also become possible to acquire new crystals that have band gaps and grid constants matching the performance of the elements. Regarding ultra-grid functional elements, new functional elements with the HET and RHET structures were made by utilizing the characteristics of the ultra grids, and performances of normal temperature operation and high speed operation were investigated. The ultra-grid structured elements have made it possible to embed ultra fine electrode structure into crystals by means of double hetero growth, and a possibility of Si-based PBT was demonstrated. These achievements lead to a belief that the targets intended at the beginning of the present research have been achieved. (NEDO)

    This paper describes the survey and development of new coal exploration technology applied in the NSW State of Australia. It is intended to develop a coal resource assessment method with high accuracy using the reflection method seismic exploration, assisted by other physical exploration methods. The Caroona area has a Permian period ground bed distributed, in which multiple number of coal layers exist. The ground bed is covered with sedimentary layers of the Triassic period inconsistently, and this Triassic period system is covered by volcanic rocks of the Jurassic period inconsistently. Faults are going through the coal beds in their upper or lower layers at locations having soft rock beds. Existence of the faults was estimated by seismic exploration using the two-dimensional reflection method, assisted by the result of the physical logging. The results were unified with the result of test drilling to identify the summary of the latent basset lines. Furthermore, the seismic exploration using the three-dimensional reflective method capable of high-level imaging of underground structures was applied to coal beds existing in depths less than 480 m. Multiple number of local and small-scale sinking were detected with time difference of 5 ms and depth conversion to 7 m. Locations, runs, and inclination were interpreted also on faults having small fall which cannot be detected by the two-dimensional method. The three-dimensional method was found capable of identifying micro structural changes and fault runs that cannot be tracked by the two-dimensional method. (NEDO)

    Described herein are the FY 1998 research and development results of solid electrolyte fuel cells. For R and D of the tubular type cell by the wet processing technique, the tests are conducted to evaluate the initial performance and long-term durability for continuous operation of the single tubular cell. For development of the several-kW class modules, computer-aided simulations are conducted. For R and D of material and substrate techniques, the thermal cycle characteristics, cell characteristics and stress of the cell modules are evaluated, in order to evaluate their reliability. The thermal cycle test results indicate that performance of the single-stage cell is unaffected by the thermal cycles. It is found by the stress evaluation that use of the separator plate having a higher thermal expansion coefficient than the electrolyte plate and use of the sealant having a thermal expansion coefficient close to that of the electrolyte plate are effective means to reduce stresses. For the research to reduce costs of the cell materials, their chemical, mechanical and thermal characteristics are evaluated. For the system research, the areas for which the compact systems are suitable and their optimization are studied. (NEDO)

    Cost reduction for the above-named solar cells is the aim of this effort. On the basis of the results of past studies, a technology is established of fabricating a thin CdS film by subjecting a CdS film to organometal pyrolysis, and this brings about a decrease in photoabsorption loss in the range of waves shorter than 500nm and a decrease in in-film reflection loss for an increase in short-circuit current density. A proximity sublimation method is used for CdTe film fabrication, which improves on film quality and film adhesion. These efforts result in the achievement of a conversion efficiency of 16.0% which is the highest in the world. Studies are promoted in a process nearer to the ultimate form, and a 30cm times 60cm large CdTe solar cell is fabricated on the basis of a patterning technique, and the product attains a conversion efficiency of 9.8%.

    Development will be made on high-performance a-solar cells as part of developing practical application technology for a-solar cells for electric power use. Development will be also made on a low-cost process technology. This paper describes the achievements attained during fiscal 1997. Quality improvement has been realized by using a high RF power hydrogen dilution process on a-Si films for front cells of lamination type cells. Four times faster film forming speed was obtained even by using the VHF plasma CVD process, with film quality equivalent to those made by using the conventional RF process maintained. By optimizing the light enclosing construction, the short circuit current was enhanced by over 20%. Discussions were given on forming homogenous a-Si films by optimizing the conditions for forming films on large-area substrates, which resulted in forming film of 30 cm times 40 cm size with good homogeneity at a film forming speed three times faster than the conventional speed. A surface electrode was formed successfully with good uniformity on a substrate with a size of 60 cm times 90 cm. Productivity greater by over three times the conventional productivity was achieved in patterning of transparent electrodes by using high-output laser. Simultaneous and collective patterning and very small and long size collective patterning were realized in a-Si film selection patterning by using the plasma CVD process. (NEDO)

    Heavy-current tiny-scale solar charger is tentatively built, equipped with a function of preventing overcharge and countercurrent in case of charging storage batteries using solar cells. Incorporated into this solar charger are a countercurrent prevention relay system, a low loss current detection system, and a MOSFET parallel connection, which allow the solar charger to be designed small in size in the presence of an increase in heat due to circuit loss. In the countercurrent prevention relay system, the countercurrent prevention diode is bypassed by MOSFETs when too large a current is generated. In the low loss current detection system, currents are detected by use of the ON resistance of the MOSFETs for the prevention of overcharge. In the MOSFET parallel connection, MOSFETs are connected in parallel for a decrease in the ON resistance. The tentatively built charger is then subjected to a performance evaluation test outside the building, and the test is carried out by measuring the temperatures of the MOSFETs and the air. As the result, it is found that the temperature of MOSFET junction of the 12A tiny-size solar charger is approximately 42.5 degC at the highest, low enough to clear the requirements. 4 refs., 7 figs., 4 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)

    A new ion exchange resin operation system which can treat fermentation broth without any pretreatment is studied. In a conventional fixed bed column pre-treatment such as membrane or centrifugal separation is required in order to prevent the clogging of bacteria in the resin layer inside. However these processes require higher capital investment and lower the yield. The new method solves these problems by treating ion exchange resin as slurry. No problem is observed in pilot scale experiments using lysine fermentation broth. The bacteria do not clog the resin phase, and elute is not contaminated, even if the bacteria concentration of the feed fermentation broth is very high (10 vel %). In addition, it is found that the amount of washing water in the new method is less than that of the conventional method. A simple numerical simulation model is also proposed and evaluated. The numerical value expresses good agreement with the experimental value, and it is proved that this model can be used for optimization of process design. (author)

    To get more wind energy, longer rotating blades and higher towers of windmills are required. Therefore, the location of windmills is limited and the initial cost gets higher. In this study, a small size windmill which can generate electricity even in a city was developed and tested. A torsion arc blade type horizontal axis windmill was designed and the blade form, number and degree of distortion were investigated. Based on the results, a small windmill was made, rotation and generation tests were carried out and it was confirmed that the windmill could be used as a small scale wind power generation. The windmill is of simple construction having 6 arc blades and no high tower is required. This paper consists of 6 sections, i.e. Introduction, Windmill model, Tested windmill, Test facility and method, Test results and consideration, and Postscript. 2 refs., 18 figs., 1 tab.

    Research and development was conducted of a technology for manufacturing an ultrathin polycrystalline silicon solar cell capable of efficiency enhancement and cost reduction earlier than the types of polycrystalline solar cells now available on the market. In this fiscal year, a silicon melt/solidification experimenting apparatus was built for manufacturing high-quality silicon ingots. Using an apparatus with its performance similar to the newly built one, a preliminary experiment was conducted involving high-purity silicon ingot manufacturing. In the experiment, boron was added to 75 kg of silicon for semiconductor devices so that its resistivity may be 0.5 ohm-cm. The silicon was melted in a quartz mold, and then subjected to unidirectional coagulation at 0.13 mm/min that started at the bottom to proceed upward. The result was a silicon ingot 44 cm times 44 cm times 17 cm (height). The ingot thus obtained exhibited 0.4-0.8 ohm-cm in resistivity distribution. Solar cells produced from the ingot showed a conversion rate of 16.9%. (NEDO)

    The paper investigates and reports the developmental trend of petroleum substitution energy in Germany. Policies for the technical development and actual introduction of petroleum substitution energy in Germany are concerned with three energies: coal, natural gas, and new energy, except nuclear energy the use of which is against public opinion. Coal is the only abundant domestic resource, but not internationally competitive because of its cost. Brown coal obtained from the open pit mining is an abundant and low-cost domestic resource, but has the environmental problem. The latest technology is actually being introduced in which the thermal power generation is integrated into gasification, and the gas/steam turbine power generation. Natural gas is advancing in the use as energy source for space heating substituting for brown coal. The technology development of new energy is promoted mainly on such wind power and solar energy as are called renewable energy. As to the development of technology using renewable energy for which the rapid increasing use is not expected in near future, the target is directed mostly to CO2 control and the third world where there are no public electric power nets. 30 refs., 10 figs., 8 tabs.

    We have developed the diesel particulate filter (DPF) in which porous metal is used for a filter because of its high thermal conductivity and a radiation heater is used for a regeneration device because of its uniform thermal distribution. In the case high trapping efficiency is required, filter thickness should be thick. The thicker filter has a disadvantage of difficulty in regeneration because of the thermal distribution in the direction of thickness. In order to improve regeneration efficiency, we designed the best filter-heater construction which achieves uniform thermal distribution by using computer simulation and we confirmed good regeneration efficiency in the experiment. 4 refs., 14 figs., 1 tab.

    On setting a position as an intermediate material for the advanced composite materials (ACM), carbon fiber fabrics is required to improve its optimization of the fiber orientation and structure of the fabrics under consideration on anisotropy of the composite materials in order to establish their higher performance. And, it also becomes important to establish energy conservation in higher order of processing containing their molding in order to make great strides the application range of the ACM. The ACM is generally a laminate comprising of some sheet-like, thin substrates arranged the reinforced fibers in one- or two-dimensional direction. As it has some high performance, mechanical properties because of the fiber orientation in a plane direction, its mechanical properties among the layers are determined by adhesion and its strength between the fibers and the resin and weak without any fiber reinforcement in its layer direction. As a method of its improvement, development of a fabrics or twisted yarns having the fibers oriented in three-dimensional direction is proceeding, but they have some limits in their fiber orientation yet and inferior productivity.

Since a microcrystalline p-layer is to act as the seeding crystal layer for the microcrystalline i-layer, it has to be very high in crystallinity and therefore is produced under high hydrogen dilution conditions. In this process, a problem arises of the darkening of the underlying transparent SnO{sub 2} electrode. Since this is due to chemical reaction on the SnO{sub 2} surface layer, blackening is prevented by shortening the film fabrication time, and then an excellently microcrystalline p-layer is obtained. Furthermore, by inserting a microcrystalline i-film buffer layer of low fabrication rate into the p/i boundary, plasma damage on the microcrystalline p-layer is inhibited for the fabrication of a microcrystalline i-layer high in crystallinity at high film fabrication rates. A high Voc is then obtained even when the microcrystalline p-layer is very thin. If the hydrogen dilution rate is too low when the i-layer film fabrication rate is high, the initially fabricated layer turns out to be thick to the detriment of film performance. On the other hand, the p-layer or the buffer layer will be etched when the hydrogen dilution rate is too high. The problem is solved by continuously varying the hydrogen dilution rate from high to low during i-layer fabrication. (NEDO)

    To reduce the manufacturing cost of semiconductors, some systems have been proposed that use a cheap and high purity Clean Dry Air (CDA). CDA can reduce process step such as wafer cleaning, because CDA flow in stocker prevents the wafer surface from adsorbing of moisture and organic impurities. We have already optimized a two-stage rotary dehumidifier and have conducted a study of methods for cheaply manufacturing air that has a low dew-point of -70 degree C to -50 degree C. We have further developed the method in which a dry dehumidifier is used, and developed an ultra low dew-point air generator. The air generator is a three-stage rotary dehumidifier in which a further stage is added to the two-stage rotary dehumidifier. The main component of the rotors is metal silicate. The air generator can supply dry air with a dew-point of -110 degree C. or less, in which the concentration in all gaseous contaminants is far below 1 ppb. We made a trial calculation of the manufacturing cost, and an average cost of 0.25 yen/m{sup 3} was obtained. (author)

    The technical art `Bekko` is one of the traditional technologies in Japan, and the materials of `Bekko` are shells of hawksbills. However, the industry of `Bekko Work` has been facing a crisis recently, because the import of turtleshell is restricted. We have therefore tried to develop new materials as substitutes for the turtleshell by utilization of horn. The noteworthy aspects in this study are as follows: (a) It has been clearly established that the horn could be reformed with amber color similar to that of turtleshell by chemical treatment using hydrogen peroxide (H2O2). (b) It is also of interest that we produced new materials like `Bekko` by mixing horn powder and turtleshell powder at the appropriate ratio and molding them in the temperature range of 110-120{degree}C. 1 ref., 6 figs., 3 tabs.

    This paper summarizes the result of a geothermal resource survey carried out from fiscal 1995 through fiscal 1997 in the Kumaishi Area located in the western center of Oshima Peninsula in the south western part of Hokkaido. The survey for this area was performed with an objective to search the spread of high temperature area continuing from the adjoining Yakumo area where the highest temperature of 233 degrees C has been confirmed in a structural test well (N63-YK-6), to identify high water permeating areas in great depth points underground, and to find possibility of existence of geothermal resources. The survey included geological and alteration zone survey, geochemical survey, gravitation exploration, electromagnetic exploration, drilling and temperature logging of five structural test wells, water injection test, temperature restoration test, core survey and hot water survey. Also performed were environmental effect survey, rock age measurement, alteration age measurement, and fluid inclusion test. As a result of the survey, it was identified that the verified geothermal hot water has been stored in granites with poor water permeability, whose low temperature has not formed convection systems spreading in wide areas despite having been heated, making each system exist in small scale independently. It was estimated that the possibility is low to expect geothermal power generation. (NEDO)

    As a turbojet engine gets a thrust by blowing out the exhaust of a gas generator, for decreasing the fuel consumption ratio is more advantageous when a bypass air quantity is made as much as possible. Therefore in the subsonic speed passenger aircrafts putting an economy in the first place, the high bypass ratio turbofan engines are used. Even in case of the subsonic speed aircrafts, in addition, for the trainer airplanes and fighters, a type to be built in the engines in the fuselages, the low bypass ratio engines with small front areas are used. When a turbofan engine with a low bypass ratio is picked up, therefore recently, it is general that a military engine with a bypass ratio under 1 (about 0.5 is frequent) is pointed, as for a development trend also from a viewpoint of the performance improvement as a military engine, an improvement of the thrust-weight ratio and specific thrust are attached importance to. In this paper, these performance parameters, a trend to make them lighter weight, and the elementary technologies peculiar to a low bypass ratio engine are described, and moreover the study and development state in Europe, America and Japan are put in order. 8 refs., 14 figs., 2 tabs.

    The turbofan engines for private aircrafts have come to have a high bypass ratio because a performance improvement is always requested. Because a turbofan engine is always required for a thrust reinforcement to correspond the stretch and weight increase of a fuselage after acquiring a type approval, making them a series to cover a certain thrust range becomes necessary. The concrete methods to reinforce a thrust are being achieved by an increase of fan diameter, a partial modification of high pressure compressor, a temperature rise of high pressure turbine inlet, a stage number increase of low pressure turbine, and a combination of these items just mentioned above. The PW 4000 series, CF6 series and RB211 series currently under production are being reinforced in a thrust by these methods. In this paper, as the representatives of some turbofan engines incorporating the most advanced technologies, as for 3 kinds of the large scale turbofan engine presently under development for the B777, namely GE90, PW4084, and TRENT800, their distinctive futures are summarized. 25 figs., 1 tab.

    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.

    A polycrystalline Si thin film formation technology is developed, which uses the flux process in which a reaction occurs between the target crystal and a flux component which is eutectic. Using this process, a crystal grain relatively large in diameter is obtained at a relatively low temperature. This method is now attracting attention as one of the technologies for producing crystalline Si film for use in thin-film polycrystalline Si solar cells. Especially when Al is used for flux, since Al is automatically doped into the target crystalline Si film, it is expected that the resulting film will serve as the ground for a photoactive layer provided with the BSF (back surface field) function which is important for the improvement of solar cell efficiency. A polycrystalline Si thin film is formed on a 2cm times 2cm-large glass substrate at a temperature not higher than 600 degrees C. It is recognized that films selectively oriented towards the (111) or (100) plane are acquired when other processes are employed. It is expected that the said Al-doped film provides a ground on which a BSF function-provided photoactive layer will be formed. (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)

    A seawater desalinating still was devised, which utilizes solar heat and combines a basin type still with a multiple effect type still. The devised still has a triangular cross section, has a seawater basin at its bottom, wherein the slope facing the sun has a double glass window, and the other slope is arranged with a multiple effect still (three-step effect system). The sun light that has permeated the double glass window heats and evaporates seawater on the basin. Majority of the generated steam is condensed at the lower face of a lowermost partition of the multiple effect section, and its latent heat evaporates the seawater contained in a wick on the rear side. The steam is condensed at the lower face of the second partition, this action is repeated sequentially to upper plates, and the heat is discharged finally into the surrounding air from the uppermost face of the multiple effect section. Seawater is supplied from the upper part onto the wick in each partition, which is evaporated, condensed and recovered at the lower part. The condensate is recovered at the lower part of each plate. The construction is simpler than the conventional downward indirect heating multiple effect type still, and the distilling efficiency is improved by 30%. Technological difficulty in the upward direct heating multiple effect type still can also be improved. 6 refs., 6 figs., 2 tabs.

    Development was made on a simplified site-use single face shear testing device and a test method that can perform in-situ and direct measurement during construction on shear strength of coarse particle materials having large diameters. The test device consists of shear frames embedded in the in-situ ground bed, a weight for vertical loading, and a traction device to load horizontal force. In the test, prescribed rolling compaction is performed by a vibration roller which presses in the shear frames into unwound banking by using a four-piece vibration roller. Crushed stones are piled on cells of the shear frames to the same height. The specified weight is placed thereon via a loading plate, which is used as the vertical load. The shear force is loaded by horizontally pulling chains connected to the shear frames by using the traction device, and is measured by a load cell. The vertical displacement is measured by two vertical displacement meters, and the horizontal displacement by one horizontal displacement meter. A verification test is continuing using the test device. Four cases with different vertical stresses can be tested in about one day. (NEDO)

    Surveys and studies were conducted to establish a practical SNG (substitute natural gas) production process. In the study of coal hydrogasification, a mathematical simulation was implemented to estimate the distribution of products with the pyrolytic reaction and the hydrogenolytic reaction controlled independently in the ARCH-2 (advanced rapid coal hydrogasification-2) process, the said two reactions representing the key concepts of the ARCH-2 process. It was then disclosed that a two-stage reaction control would increase the liquid yield. Also, a tentative calculation was made of gas cooling efficiency and cost performance in a process capable of achieving the target liquid acquisition rate. It was then found that BTX (benzene, toluene, xylene) production up to approximately 15% in terms of carbon was feasible and that the SNG price would be 29.03 yen/Nm{sup 3} with benzene priced at 90 yen/kg, these promising a better result than in the ARCH-1 process. The gas cooling efficiency of the ARCH-2 process was but 72.0% or less, however, which demanded improvement. Studies were made, based on the results of studies in progress since fiscal 1990, about what the hydrogasification process for Japan to develop should be. (NEDO)

    This paper describes a thin-shaped lightweight maintenance free motorcycle battery used in a motor scooter, a new product from Honda Motors launching its sales in 1992, as well as the related structural development thereof. The points aimed at in the development include more utilization of available space in a vehicle, improved maintainability, and adoption of perfect instant activation system (dry-charged system) which makes a battery serviceable upon initial filling of electrolyte. Attentions have been given on reducing the battery volume by 30% and weight by 20% compared with the conventional batteries, and ensuring interchangeability, leakage-free performance, and free and easy replacement. Contrivances for practical application have been given on assuring low-temperature high-rate discharge performance for reliable engine starting. Devised also are the thinner battery plates, better vibration resistance, longer life, uniformed plate thickness, higher separator porosity, and better stability in plate group pressurization. Better performance than the conventional batteries was realized by improving parts construction and mounting systems, including one-touch terminal connection, fast coupling of terminal posts, soldering, and fuse built-in couplers.

    In a facility utilizing the subterranean space at the great depth of about 50m or less from the surface in particular, the airflow velocity monitor utilizing ultrasonic waves is considered as an airflow anemometer suitable for the environment of an underground airway network. In this paper, the results of the application test and the long term demonstration test both conducted at Matsumine Mine and Fukazawa Mine of Hanaoka Mining Industry are mentioned which concern the newly developed airflow velocity monitor utilizing ultrasonic waves. The features and performance of this ultrasonic wave monitor are roughly as follows; since a small ultrasonic wave transceiver can be installed on the surface of the airway wall, the transceiver does not become an obstacle for traffic in the airway and the average airflow velocity in the airflow path can be estimated with accuracy better than that of the anemometer for point measurement. The airflow direction at the underground airway can be detected. The responsiveness to airflow velocity fluctuations is relatively good. The abrupt ups and downs of output due to passing transportation machines can be detected. The measuring circuit has been simplified by the analogue treatment of time measurement. The average airflow velocity at the airflow velocity profile can be estimated through multiplication by 0.93 of the airflow velocity value measured with the monitor. 11 refs., 16 figs., 1 tab.

    The project aims to enhance the stability of amorphous solar cells. For elevating TCO (transparent conductive oxide) substrate transmittance to an ultrahigh level and for obtaining amorphous layers less to suffer photodegradation, efforts were made to develop substrate materials stable upon exposure to plasma and low in defect density. In the study of TCO, a high-transmittance glass substrate was employed and TCO was made thinner, and the specimen achieved transmittance of 91.3% or 6.3% over that of the conventional type. In the study of low reflection films, it was found that their transmittance came to be stable and remain so after 150 days after a weatherproof test. In the study for stability enhancement, optimization was carried out for a plasma resisting Ga{sub 2}O{sub 3}-added ZnO film for the manufacture of a substrate material capable of properly behaving in a high-speed a-Si film fabrication process. Low-temperature film fabrication was studied to enable low-cost manufacturing, and it was learned that a 4 times 10{sup -4} ohm/cm low-resistance film was obtained by sputtering Ga{sub 2}O{sub 3}-added ZnO where magnetism was intensive at room temperature, that films excellent in crystallinity were obtained by the same method even at low temperatures, and so forth.

This paper summarizes the achievements in fiscal 1999. In developing the high-quality ingot manufacturing technology, discussions were given on a method for assessing impurities and crystal defects by using the total reflection scattering type infrared tomography, and on the optimal solidifying and cooling conditions during the ingot manufacturing by using simulation calculation for solidification. As a result of analyses and discussions, such findings were found effective that the ingot should be solidified through making the solid-liquid interface shape flat, and the temperature falling rate in an ingot should be maintained constant. In developing the high-efficiency cell making technology, discussions were given on the optimal construction based on a simulation that assumes the light sealing structure using the RIE method, and on the optimal construction of polycrystalline silicon solar cells by using a device simulator (PCID). The important factors in achieving a conversion efficiency of 20% are the light sealing structure, surface passivation, and substrate thickness. (NEDO)

    The target is a low-cost CdS/CdTe solar cell of a large area (60cm times 90cm), the establishment of mass-production technologies for the cell, and the enhancement of production efficiency. A thin film formation technology of subjecting CdS film organic metal to pyrolysis is established, which reduces photoabsorption loss in the shortwave domain of wavelength of not longer than 500nm, reduces reflection loss in the film, and improves on short-circuit current density. Improvement is also achieved on CdTe film quality and junction quality by use of a proximity sublimation method in a vacuum, when a conversion rate of 16.0% (1cm{sup 2}) is attained which is the highest in the world. Based on the results of the above-said efforts, a 3.3mm-thick glass substrate is employed for CdTe film to develop into a 30cm times 60cm-large size, with the film thereon uniformly thick over a large area thanks to a normal pressure proximity sublimation method. Studies are made toward a process nearer to the ultimate product and, using the patterning technique, a 30cm times 60cm-large CdTe solar cell is tentatively built realizing a conversion rate of 9.8%.

    A pressure sensor more reliable than the conventional types and a tire pressure measurement system using a plurality of sensors of the said reliable type have been developed. The sensor is an inverted T in shape, the upper surface of the vertical beam thereof receives the pressure, and the two ends of the horizontal beam are fixed. The load per unit area imposed on the pressure receiving surface is separated into three components, the X and Y components in the tangential direction are sensed by the vertical beam while the Z component in the vertical direction is sensed by a distortion gauge attached to the horizontal beam. For the measurement of the contact pressure distribution for the entire contact surface, a measuring device was developed, comprising a multiple point contact pressure gauge with 30 sensors of the reliable type discussed here embedded therein, a tire rolling tester, and a data processing unit. A tire wear estimation test was conducted using this pressure sensor and a contact probe type slip sensor, and it was found that a tire of a greater friction energy ratio is easier to experience abnormal abrasion and that the new pressure sensor is useful in estimating abnormal abrasion. Further, it was indicated that the present measuring device is applicable to the analysis of the mechanism wherein shaft force results from contact pressure on the soil. 3 refs., 11 figs., 3 tabs.

    High temperature and high pressure steam has been investigated for the high efficiency waste power generation technology development. The steam temperature below 300 centigrade is currently employed to avoid the corrosion of superheater, and the generating efficiency is less than 15%. Practical application of 500 centigrade and 100 kg/cm{sup 2} is planned by developing corrosion resistance materials. Environmental load reduction technology has been also developed. For the external circulation type fluidized bed furnace combustion tests using dummy waste in fiscal 1995, the temperature control at bag filter was effective for suppressing the dioxins. When using waste plastics, HCl could be reduced by blowing Ca compounds. Various Cr-Ni-Mo-based alloys have been developed as a corrosion resistance superheater tube material, and are currently tested. For the environmental load reduction technology, the development of pulse plasma exhaust gas treatment method has been continued from fiscal 1993. In fiscal 1995, this method was confirmed using a small-scale test unit, and also tested using a 5000 Nm{sup 3}/h bench-scale unit.

    The purpose of this study is to combine seismic activity and volcanic activity by reproducing the formation process of the crustal structure from a physical viewpoint or developing as its extension a numerical simulator which can predict the future. The phenomenon to which attention is especially paid at present is a relation between the dynamic process and the thermal process in the domain including the crust or the upper mantle. Namely, to elucidate the formation process of the crust structure, diastrophism also including seismic activity, igneous activity, etc., it is important to evaluate effects of the behavior of heat supplied from the deep on the dynamic process. In the finite element method, it is not easy to make the effect of gravity reflect to the calculation for boundary conditions. Accordingly, it is general to pay attention to stress difference, considering that stress by gravity is in proportion to static rock pressure stress. Further, to realize interaction between the thermal process and the dynamic process, effects of thermal stress are expressed combining the heat conducting analysis and the plastic flow analysis. 3 refs., 7 figs.

    In order to heighten the accuracy of small size seamless tube wall thickness, hot wall thickness gauge was developed to be installed, immediately behind the finishing/rolling mill, for the on-line measurement, of which the method was by the parallel-beam transmissivity of gamma-ray. The measurement unit, aiming at flexible manufacturing system (FMS), is completely automated in correcting the accuracy, changing the sizes, etc. The damping characteristics of gamma-ray beam can be expressed by a characteristic function, taking the outside diameter and wall thickness of subject tube as parameters. The functional calculation, as based on measurement of transmitted quantity of gamma-ray through the three-dimensional steel material, changes, depending upon the outside diameter, wall thickness and material specification of subject tube. System was so applied as to calculate it therefore on a case-by-case basis. Though in the vicinity of tube end, the transmitted quantity of gamma-ray is largely influenced by the horizontal dislocation, that influence is slack in the middle part of tube. Therefore, the cross sectional division was made dense and sparse in the end part and middle part, respectively of tube, which division could diminish the error from several percent to less than 0.1%. The static noise was compressed by the optimized digital filter. That gauge is presently applied for the operational administration of small size seamless tube rolling. 2 refs., 11 figs., 2 tabs.

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

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

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

    This project was received by Optoelectronic Industry and Technology Development Association from NEDO, and aims to contribute to the improvement of Indonesia's environmental administration through the development of an air pollution observing laser radar (LR) and of an environmental information network system fit for use in the country in cooperation with Indonesian engineers. LRs will be installed at several sites in an urban area where environmental problems are increasingly serious, and a observation network system will be constructed to link the laser radar sites. The observed data will be collected, analyzed, and processed by an observation data processing center for the investigation of the three-dimensional spatial distribution of air pollution to determine the actual state of air pollution over an urban area. The laser radars and the network will be placed in the city of Djakarta. The Indonesian authority responsible for the project is Indonesian Institute of Sciences. In fiscal 1994, part of the equipment (difference absorbing LR) was designed and manufactured, the design of the environmental information network system was developed, and various researches required in this connection were conducted.

    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.

    Recently, environmental pollution by a large amount of undecomposable waste has became a serious problem. Therefore, biodegradable polymers, which can be degraded by environmental species such as bacteria and enzymes, have been studied extensively. Most of the biodegradable polymers prepared so far were polyester derivatives such as poly(hydroxybutyrate/valerate), poly(lactide) and poly(glycolide). The degradation mechanism is the hydrolysis of the ester groups in the main chain of the polymer which is facilitated by enzyme degradation. Most of the mass-produced polymers, however, are vinyl-polymerized plastics such as poly(ethylene), poly(propylene) and poly(styrene). There is no technology on the degradation of such vinyl polymers except in the lithography field, in which it is known that some vinyl polymers can be used for posi-type resists by decomposition with UV or electron-beam (EB). For creation of degradable polymers, the following three factors must be considered Purpose of the project seriously; 1) What degrades the polymers? 2) Row long does the polymer maintain the initial properties? (Time course of the mechanical strength, etc.) and 3) Bioactivity of the liberated oligomers. The aim of our work is the creation of new polymers which can be easily controlled by the above three factors. If we can degrade the polymers from the end of the polymer chain, i) we can control several properties of the polymers in the degradation such as degradation source (pH, light,, UV, EB, etc.) and rate of the degradation by changing the structure of the end group; 2) production of oligomers, which may induce a significant problem in terms of bioactivity, can be suppressed because of the depolymerization from the end of the polymers (only the monomer will be liberated). In this project, we investigated to synthesize the end functionalizations of poly({alpha}-methylstyrene) derivatives and their degradation characteristics using temperature, acid and alkaline conditions. To induce degradabilities in polymers in response to environmental conditions, the end-modification reactions of poly({alpha}-methylstyrene) (PMS) derivatives were carried out. When diphenylphosphine chloride was used as a modifier for the living end of para-substituted PMS, the coupling efficiency was ca. 50%. 2-Phenylallyl halide derivatives such as 2-phenylallyl bromide, 2-(4-tolyl)allyl bromide, and {alpha}-trifluoromethylstyrene were found to be suitable end-modification agents. For example, {omega}-2-phenylallyl PMS was prepared with almost quantitative functionality by the reaction of the living PMS with 2-phenylallyl bromide. In a similar way, {omega}-3, 3-difluoro-2-phenylallyl and {omega}-2-(4-tolyl)allyl PMS derivatives were synthesized. Based on thermogravimetric analysis, onset of the degradation temperature of the end-modified PMS derivatives decreased in the following order: {omega}-hydrogen- > {omega}-3,3-difluoro-2-phenylallyl- > {omega}-2-phenylallyl- > {omega}-2-(4-tolyl)allyl-PMS. Actually, the onset temperature of {omega}-2-(4-tolyl)allyl-PMS derivatives was 50 degree C lower than that of {omega}-H-PMS derivatives. These results indicate that the active species is produced effectively at the end unsaturated bond, which initiates the depolymerization of the polymer at rather low temperatures. Ionic degradation of these polymers was also investigated using butyllithium as an anionic initiator and methanesulfonic acid as a cationic initiator Tendencies similar to the thermal degradation were observed. Therefore, it is concluded that a 2-phenylallyl substituent at the end of the PMS chain induces effective degradation through several mechanisms such as radical, anionic and cationic depolymerization reactions.

    This paper describes the assessment method of measures mitigating heat island phenomena in urban areas. The heat island phenomena were classified into meso-scale with 100 km-scale, block-scale with several km-scale, and building-scale with 100 m-scale. Urban thermal environment simulation model was developed in response to each scale. For the development, regional data using aircraft and artificial satellite observations, surface observation and thermal environment observation at Shinjuku new central city of Tokyo, and artificial waste heat actual survey data in the southern Kanto district were utilized. Results of the urban thermal environment simulation were introduced as an application of this model. Temperature distributions of the heat island in the Kanto district were simulated with considering urban conditions near Tokyo and without considering it. Daily changes of wall surfaces of high buildings and road surface were calculated. Increase in the air temperature in the back stream of building roofs with increased temperature was determined. 4 figs.

    In the refining process for the production of copper from pyrites, heat treatment is carried out in a neutral atmosphere so that part of the sulphur will be collected in the form of simple sulfur and that pyrites naturally low in reactivity will be made active. A basic study is also conducted of a very high speed electrolytic method. The chemical aspects of pyrites which are various in composition (mainly CuFeS2) are clarified by X-ray diffraction, and then is subjected to heat-treatment in a 773K-1073K argon atmosphere. There is a decrease in the amount of sulfur at a temperatures not lower than 973K. The X-ray main diffraction line splits for the emergence of some lower angle diffraction lines. The specimen is then subjected to a leach test in a copper chloride base liquor, to disclose that leachability grows remarkably higher in the presence of a great change in the X-ray diffraction lattice constant. An experiment follows in which an electrolyte is allowed to flow at a high speed for accelerating the rate of electrolytic refining in an effort to prevent the passivation of anode and deposition of dendrite on the cathode that is apt to occur when the current density is high. Passivation is prevented when the flow rate is 10m/min or higher in the vicinity of the anode surface for the formation of a smooth electrodeposited surface. 2 refs., 2 figs., 2 tabs.

    Experiment reveals the characteristics of low rank coal serving as a desulfurizing material in fluidized coal bed reactor with oxygen-containing functional groups exchanged with Ca ions. This effort aims at identifying inexpensive Ca materials and determining the desulfurizing characteristics of Ca-carrying brown coal. A slurry of cement sludge serving as a Ca source and low rank coal is agitated for the exchange of functional groups and Ca ions, and the desulfurizing characteristics of the Ca-carrying brown coal is determined. The Ca-carrying brown coal and high-sulfur coal char is mixed and incinerated in a fluidized bed reactor, and it is found that a desulfurization rate of 75% is achieved when the Ca/S ratio is 1 in the desulfurization of SO2. This rate is far higher than the rate obtained when limestone or cement sludge without preliminary treatment is used as a desulfurizer. Next, Ca-carrying brown coal and H2S are caused to react upon each other in a fixed bed reactor, and then it is found that desulfurization characteristics are not dependent on the diameter of the Ca-carrying brown coal grain, that the coal is different from limestone in that it stays quite active against H2S for long 40 minutes after the start of the reaction, and that CaO small in crystal diameter is dispersed in quantities into the char upon thermal disintegration of Ca-carrying brown coal to cause the coal to say quite active. 5 figs.

    Studies are conducted to develop a new wet method for copper concentrates to replace the conventional dry smelting method for the settlement of problems involving the processing of impurities for environmental protection. A specimen of pyrites polycrystals is subjected to leaching at 80 {degree}C in a strongly acidic cupric solution. Findings are that the element sulfur generated in this process does not impede leaching and only approximately 4% of the sulfur is oxidized into sulfur ions; that the presence of more than 2g/liter of bromide ions produced during bromine-aid leaching of gold changes the structure of sulfur for the inhibition of leaching; that circulation of a bromine-containing leaching liquid is not desired since even a small amount of approximately 0.02mol/liter inhibits the leaching rate. Controlled potential electrolysis is performed for the anode in an acid solution containing CuCl, NaCl, and NaBr, for the observation of oxidation/reduction potentials predicted by Nernst`s equation. It is then disclosed that bromine is more effective than chlorine in gold leaching and that the solution potential during leaching agent regeneration enables the monitoring of solution constitution. 2 refs.

    This paper describes actual condition and measures against heat island (HI) phenomena in large urban areas with buildings. Tokyo was selected as a model. To extract typical pattern of daily change of air temperature, statistic analysis was conducted using the existing air temperature data at 100 points in and near the city of Tokyo. As a result, five patterns were obtained, i.e., central city, sea/land water affecting zone, thickly settled suburbs, garden city, and countryside. Each one point was selected in each pattern, to measure the underground temperature. It was found that the effect of HI can be easily evaluated from the underground temperature. It was suggested that the HI effect in the central city is estimated to be around 3.6 {degree}C. The measures mitigating HI were divided into the thermal balance improvement in the whole district and the temperature improvement of living space by homogenization or inhomogenization. Energy conservation was investigated for improving the thermal balance which can be practically conducted. According to the measures, it was found that the air temperature in the central city can be decreased by about 0.5 {degree}C at maximum. 3 figs., 1 tab.

    The new biological deodorization device was developed using dried activated sludge as deodorant. Activated sludge obtained from a waste water treatment plant was dried at room temperature to protect from extinction of microorganisms in it before its charge into the device, and washed by water only as required. Offensive odor substances were oxidation-decomposed by microorganism after their adsorption into sludge surfaces, while microorganisms survived for a long time while getting such substances as nutritive sources. As basic deodorization characteristics were studied with the experimental device and artificial odor gases, more than 99% of 200 and 2,000 ppm H2S were removed at space velocities of 400/h and 33/h, respectively, together with nine typical offensive odor substances. As the result of demonstration tests with the small test device installed in a public waste water treatment plant, a high deodorizing efficiency was retained for 10 months or more, and its running cost was as low as 75% of that of current systems because of only one necessary washing every month. 3 refs., 14 figs., 12 tabs.

    As a part of diffusion and promotion of electric cooking apparatuses, a non-duct IH smokeless roaster has been developed for roast meat restaurants in cooperation with Hitachi Home Tech. Smoke and odor in the room can be removed without using exhaust duct by incorporating smoke and odor processing equipment into the main body. For the developed roaster, IH was adopted as a heat source with less smoke and exhaust gas compared with city gas. Generated smoke and odor are removed by the electrical precipitator and the deodorant catalyst incorporated in the main body. After the treatment, exhaust gas is emitted in the room. This roaster has characteristics as follows. This roaster can be used at high-class roast meat restaurants for avoiding smoke and odor, and can be brought in banqueting hall of hotels. Since it does not have a duct, there is no danger of fire. It is easy to change the layout of guest room. Since the IH system has less exhaust heat than the gas system, increase in room temperature is moderate, which results in the reduction of air conditioning load. 8 figs., 3 tabs.

    The continuously variable transmission control system consists of generation of a desired gear ratio and a servo gear ratio system. The servo gear ratio system must provide the desired response at all times without being influenced by external disturbances. These include oil pressure as well as variation in performance due to operating conditions or changes occurring with us. We have developed the servo gear ratio system incorporating a robust model matching method, which enables the belt continuously variable transmission to satisfy this performance requirement. 2 refs., 9 figs.

    A belt CVT system requires a large oil flow during shifts compared with a conventional automatic transmission. And the hydraulic pressure is higher for high-powered engines. As a result the oil pump is bigger and efficiency is lower(fuel consumption is higher). This system develops high pressure in three stages first reducing the hydraulic control system so that a small oil pump is attained. 8 figs.

    Recent diesel engines require a higher performance and a longer life. Due to higher cylinder pressure, the operating load and temperature of piston pin bushings become higher. Therefore, higher load capacity, higher wear resistance and higher corrosion resistance are required for piston pin bushings. For this reason, we have studied the effect of components added to copper alloy upon the corrosion resistance and the effect of hard particles dispersed in copper matrix upon the wear resistance and the influence of hard particles on the machinablity of materials. Based on the experimental results, we have developed a new bushing material improving wear and corrosion resistance. 17 figs., 3 tabs.

    Increasing vehicle speed and power, high-performance synchronizer ring of manual transmission is required. We develop double layer sintered synchronizer ring for high performance and cost reduction. The main structure is consisted of ferrous sinter for high strength. In this paper, friction materials of sintered synchronizer ring are studied. We can get the good friction and anti-wear property by means of hard particles (FeTi, ZrO2), solid lubricant (Graphite) and suitable porosity in brass sinter matrix. And we also achieve high joining strength between double layers adding Cu-P material. 6 refs., 13 figs., 2 tabs.
