A processing method was proposed in which to manifest magnetic characteristics up to the theoretical value level, crystallization of magnetic alloy amorphous was controlled and size/configuration of precipitated micro-fine crystals are made ideal. For the development of environmental purification use high functional catalysts, experiments were conducted on the heightening of purity of materials.

These are separated from the non-ionized components by electrostatic field application, and only the ionized atoms are vapor-deposited on substrate. The separation accuracy was good. Plasma excitation of raw gas was done independently for every component, and the multi-source excitation plasma CVD was proposed which is film-formed on the substrate of which the periphery was separately controlled.

    Described herein are the FY 2000 results of the research and development of heat-resistant materials, aimed at increasing operating temperature of gas turbines not equipped with a cooling system and thereby further improving their thermal efficiency. The program for design/evaluation of high-strength, Nb-based solid solution alloys develops the Nb-based alloy reinforced with a solid solution comprising 5 to 30% of Mo and 5 to 15% of W, all by atom, simultaneously dissolved. The program for design/evaluation of high-strength, Nb-based composite materials confirms effectiveness of incorporating Si in a Nb alloy and separating silicide in the Nb-based solid solution alloy matrix as the combined mechanism of reinforcing the alloy. The program for creation/evaluation of Nb-based parts which withstand superhigh temperature finds that the discharge plasma method gives the structure, in a very short time, almost on a level with that given by the solution solidification method. The program for oxidation resistance improving technologies develops the electrochemical process for forming the oxidation-resistant coating film. The stable oxidation-resistant performance is observed in the preliminary test, because the sample loses no weight when exposed to around 1000 degrees C in air for 10 hours. (NEDO)

    With the purpose of establishing innovative manufacturing technology for microstructure steel having a crystal grain size of about 1 {mu}m or less and a dimensional thickness of 1 mm or more by homogeneous multi-phase structure steel making, R and D was conducted, with fiscal 2000 results compiled. This year, R and D, using a multi-functional integrated test rolling mill, resulted in obtaining ultra-fine grained steel, a steel plate of 5 mm in thickness and 100 mm in width with grains of 1 {mu}m or less homogeneously in the thickness direction. In the investigation on the characterization by the steel plate sample thus obtained and on the method for preventing degradation in elongation, it was proved that an ultra-refined microstructure containing martensite or austenite as the secondary phase has a suppressing effect on the degradation in elongation. Further, examination was made on the widening of a process window for the practicability in the future and on the optimization of large strain deformation conditions. In the method of analyzing and evaluating ultra-refined microstructures, an analysis technology such as an in-lens SEM was proved to be extremely effective on the analysis of microstructures of supermetals created by large strain deformation as well as on the observation of microstructures of a submicron level.

    Survey has been conducted to develop laser processing technology utilizing the interaction between substance and photon. This is a part of the leading research on photon technology development. The photon technology development is aimed at novel technology development highly utilizing the quantum nature of photons. In the field of laser processing, high quality photons are used as tools, special functions of atoms and molecules will be discovered, and processing for functional fabrication (photon machining) will be established. A role of laser processing in industries has become significant, which is currently spreading not only into cutting and welding of materials and scalpels but also into such a special field as ultrafine processing of materials. The spreading is sometimes obstructed due to the difficulty of procurement of suitable machines and materials, and the increase of cost. The purpose of this study is to develop the optimal laser technology, to elucidate the interaction between substance and photon, and to develop the laser system and the transmission and regulation systems which realize the optimal conditions. 387 refs., 115 figs., 25 tabs.

    Efforts are made for the creation of high melting point metal-base materials to replace the currently-used Ni-base superalloys for the turbine to withstand higher operating temperatures. The main efforts made in fiscal 1997 are outlined. As in fiscal 1996, Nb-base solution alloys, in which solution reinforcement elements such as Mo and W are alloyed, are manufactured by button arc melting and tested for mechanical properties and texture/characteristics. In the designing and evaluation for a strongest Nb-base composite material, Nb-base composite materials are manufactured by use of particle dispersion-strengthening attained by addition of intermetallic compounds or elements to contribute to the formation of oxides, carbides, or nitrides. Nb-base composite materials may also be manufactured by use of eutectic-strengthening attained by utilizing crystallization in the process of coagulation. The resultant Nb-base composite materials are evaluated for their dynamic characteristics at high temperatures. In the development and evaluation of technologies for creating Nb-base materials for high-temperature components, larger specimens as heavy as several kg are tested in line with small specimens for basic studies, and the results are utilized for alloy designing for high-temperature materials. 50 refs., 97 figs., 15 tabs.

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

Since the impurities in the sputtering atmosphere is easily thought to affect strongly on the initial film growth, we will develop the highly purified sputtering atmosphere to establish a fabrication technology of ultra thin metallic films with desirable microstructure. A specialized multi-sputtering system which has extremely clean atmosphere (impurity level: 1/10000 compared to conventional systems) were realized by (a) decreasing out-gassing rate from vacuum chamber, pumping system, cathode, robot, etc. and (b) using ultra-clean processing gas. The base pressure was 8 x 10{sup -12} Torr (XHV) and the build-up rate was less than 1 x 10{sup -8} Torrl/sec. From the correlation between the microstructure and magnetic properties of a part of spin-valve GMR films, the guiding principle for the microstructural design were clarified to induce the exchange coupling effectively at the ferro/antiferromagnetic interface and to enhance the GMR effect at the magnetic/non-magnetic interface. The mechanism of' Cr segregation on the grain boundaries was clarified, in thin film media deposited under ultra clean sputtering process. The material specification of the magnetic ultra thin film media for high density recording with low media noise were designed from view of the thermal agitation. (NEDO)

    This paper describes the laser material processing. Laser is artificial light that uses the amplification based on the induced emission of light. It is very excellent in directivity and monochromaticity. The high power density and concentration characteristics of laser enable a variety of high-performance processing such as junction, removal, reforming, and addition. Excellent controllability (that facilitates the automated processing), transmission performance (the processing by energy transmission in long range space is most suitable for laser), and non-contact processing (that contains no wearing, noise, and contamination) are great advantages that the existing processing method does not have. In the wide wavelength area between ultraviolet and infrared areas, the laser that can be used for material processing is very wide over the range of the continuous oscillation to the ultra short pulse of a nanosecond order. The thermal processing accompanied by melting and evaporation as well as the non-thermal processing (quantum processing) by a photochemical reaction is also available as the type of processing. The processing used for manufacturing technology is almost thermal processing including removal, junction, reforming, and addition. The thermal processing covers the range of electronics to heavy industry. 29 refs., 12 figs., 2 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.

    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.

    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.

    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.

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.

    To develop a novel process for copper concentrates which includes leaching of copper with acidic cupric chloride solutions, aiming at the recovery of sulfur in its elemental form, and leaching of gold from the residue with dissolved bromine. The effect of bromide ions on the leaching of chalcopyrite with 1.0 mol dm{sup -3} CuCl{sub 2} has been investigated at 353 K, and it was found that bromide ions have no influence on the leaching rate and the morphology of elemental sulfur deposited on the surface of chalcopyrite. Dissolved bromine has trivial effects on the morphology and oxidation of porous elemental sulfur covering the residue. However, the dissolved bromine even at 0.02 mol dm-3 depresses the leaching rate of chalcopyrite significantly. Electrotechnical oxidation of cuprous ions, chloride ions and bromide ions in the solution has examined to understand the regeneration of leachant, and it was found that these ions are oxidized simultaneously on the anode surface under the condition of galvanostatic electrolysis, but these oxidants diffuse toward the bulk of solution and react with their reductants. Thus the redox potential of the solution increases gradually showing the temporary stagnation in potential for oxidation of Cu{sup +}, Br{sup -} and Cl{sup -} ions respectively. (NEDO)

    Application of ion beam processing to 2-dimensional shapes in the past has been limited to flat shapes or small areas. There is a 3-dimensional plasma-based ion implantation (PBII) technology for which high-density plasma is generated using plural metal ion sources and gas ion sources for the application of pulse voltages. Using this technology, ions are implanted into intricate shapes, large areas, and surfaces of 3-dimensional shapes, and surface reforming is accomplished through thin film formation. It is low in cost and high in productivity, and finds a great demand for use in the fabrication of members of large and complicated engines for automobiles, spacecraft, and aircraft, members of precision machines, and members of electric power facilities and chemical plants where high resistance to abrasion, corrosion, and heat are mandatory. Research and development for its practical application, however, has just started and, before its commercialization, technologies have to be completed involving surface treatment using gas plasma for ion implantation, thin film formation using metal ion plasma, and their hybrid. Similarly important is the technology of generating homogenous plasma. This new technology is expected to enhance economic efficiency, provide means to deal with environmental matters, and improve on energy efficiency. An outline of the proposition for the project is compiled in this report. (NEDO)

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

    Financial assessment is carried out by estimating the liquefaction product cost (selling price) at which the predetermined rate of return on investment is to be earned, which is calculated by the DCF (discount cash flow) method. The cash flow is determined from the net after taxes for each business year, and the balance after the subtraction of long- and short-term borrowings is converted to the present worth as of the operation commencement year at the predetermined discount rate, and a total is calculated for the period. When the difference between the total and the equity does not vanish, the coal liquid selling price is changed, and this process is repeated until the difference vanishes. If a 20% reduction in the plant construction cost is feasible, the coal liquefaction product will be competing with the crude oil in the market in around 2030. Although the financial analysis is a profitability analysis from the fund providers' viewpoint, the benefit as seen from the project siting country needs to be assessed by an economic analysis, and probabilities are that, in the presence of great profits, the project will materialize if the two are found to earn more than average after the profits are impartially divided. Japan's benefits and expenditures are compared and subjected to an economic analysis, and a result of 6-15% is obtained. This means that the project will realize in case EIRR (economic internal rate of return) is higher than the fund procuring cost of 11%. (NEDO)

    Research and development was conducted for enhancing productivity and energy conservation by rendering continuous and automatic the electromagnetic casting process for manufacturing polycrystalline silicon substrates for solar cells. In the manufacture of ingots for substrates by continuous electromagnetic casting, the chuck type system for feeding power to the melt plasma was replaced by a roller type system, and the power feeding position was moved to the high temperature region. Also, an on-line ingot slicing technique was established. In the manufacture of substrates at a slicing rate of 300 {mu}m/minute, productivity of 115,000 wafers/month, yield of 98%, and thickness tolerance of 30 {mu}m were achieved. A high-speed cleaning technique was developed using a jet stream, by which the cleaning time was reduced to 5 minutes and the slurry recovery rate was elevated to 95%. Based on these, substrate-related costs in the case of 100 MW/year production was calculated, which resulted in a cost of 98.8 yen/wafer (target: 103.3 yen/wafer) for manufacturing 15 cm square substrates from ingots and in a 15 cm square substrate slicing and cleaning cost of 135.1 yen/wafer (target: 135.4 yen/wafer).

    Coal ash is a substance that has been mixed into minerals in the earth`s crust during their coalification process. Estimation was made on what kinds of mineral composition have been mixed into coals. Noted first was the kinds of compounds contained in the ash, wherein the ratios of mass in the compounds and minerals were correlated, and selection was made on minerals which are thought correlated. The selection criterion was based on minerals containing silica, alumina, iron oxide, lime and magnesium as compounds. Then, a phase equilibrium line diagram was used to estimate compositions and melting points of minerals which are thought to have been produced from these compounds. By comparing the estimation with the measured melting points of the ashes, mineral compositions thought reasonable were all selected. Assumption was possible on minerals that are thought to have been transferred into coal ash. Compound indications of ashes from 29 kinds of the world`s typical coals were replaced with the subject minerals and expressed as mineral compositions. As a method of calculation, stoichiometric coefficients for each mineral were determined by taking material balance in atomic/molecular levels in masses of compound aggregates and mineral composition aggregates. 7 tabs.

    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. For the latter method, studies are conducted for the development of, and for the establishment of technologies for designing, synthetic gas production technologies in the development of a heat exchanger type composite reforming furnace and a fluidized bed methanol production process, the development of a catalyst manufacturing technology for fluidized bed practical application, the development of a fluidized bed methanol production technology, and the optimization of the process and its economic efficiency.

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

    The effort aims to develop a reactor and its peripheral devices and process management technology therefor and to develop chlorosilane hydrogen-reduction process technology as part of the endeavors to develop a low cost production process for silicon for photovoltaic cells for the purpose of building a model plant capable of approximately 10 tons/year in terms of SOG (spin on glass) silicon. A study is made of ten operations (total reaction time of 2,264 hours), and it turns out that the electric power consumption efficiency is near the initially planned value. The yield of Si is, however, but 16.5% which is lower than the initially planned value of 20%. The value is elevated to 18% by raising the reactor temperature. To prevent overcleaning, a reactor with its internal walls experimentally coated with SiC is tested. The problems with devices other than the reactor tube are extraction rendered difficult by anomalously grown granules and processing devices choked by Si powder contained in waste gas after reaction. The first problem is settled by modifying the extraction tube but the other still needs a remedy. The produced granules are found to be high in quality. The seed producing roll crusher is operated for a total of 92 hours yielding 857kg in total. (NEDO)

    In the study of a corrosion resistant high sensitivity gas sensor, the following two technologies are needed: decrease in impurities of materials for super-higher purity, and formation of films with physically high quality such as orientation and homogeneity. Experiments were made on laser excitation separation refining, CVD, laser ablation, super-high vacuum, etc. For the stabilized formation of high-adhesion thin/thick films, studies were carried out of the surface activation for processing substrate surface before film formation, interface counter diffusion in thin film formation process, and the technology for combination of these. The higher-order structure control of materials was attempted using the reaction field combined with the photochemical reaction by the high grade photon field, based on the molecular beam vapor-deposition technology under super-high vacuum. In the synthesis of materials by the photon combined reaction field, studies were made of the design/process of a dynamic device which reacts like pulse the photon/high pressure/strong magnetic field on carbonaceous materials and a static combined reaction field device by the stationary high pressure field.

    Studies are conducted to enlarge the diameter of polycrystalline Si castings and to develop a low-loss slicing method using silicon nitride powder as mold releasing agent. The apparatus for Czochralski's pulling process is improved and tested using SEG (selective epitaxial growth) Si, and now the casting of a 150mm-diameter ingot is feasible. Also, test production of a 94mm-square wafer as specified by NEDO (New Energy and Industrial Technology Development Organization) is successfully carried out. Difficulties in separating the mold releasing agent from the crucible are solved by changing the Si{sub 3}N{sub 4} power solution from PVA (polyvinyl alcohol) to ethyl silicate. The design, manufacture, and installation of the important parts of the system for the mass production of castings are now complete. The crucible is designed to be movable relative to the heater section, and the molten Si is allowed to cool and solidify from the bottom upward. In relation with the development of low-cost wafer manufacturing technologies, low-loss slicing methods are studied. It is concluded that under the current circumstances a multi-blade saw is more promising than the multi-wire saw in view of the damaged slice rate, processing speed, operating cost, and maintainability.

    Research and development has been performed on a scrap melting process to make dioxins emission concentration to 0.2 ng-TEQ/Nm{sup 3} or less in steel making electric furnaces. The testing facility is of semi-sealed structure, consisting of an arc dissolution furnace, an exhaust gas combustion section, an auxiliary combustion chamber, and a quenching chamber. In the arc dissolution chamber, oxygen and coke are blown in at the same time as turning the arc power supply on, and then secondary combustion air was blown in to burn carbon monoxide gas generated from steel melting. The temperature was raised to about 850 degrees C at which dioxins are decomposed in the auxiliary combustion chamber, and then quenched to 200 degrees C or lower in the quenching chamber to prevent recombination of dioxins. As a result of the test, the exhaust gas temperature after the combustion was estimated to have reached about 900 degrees C at which dioxins are decomposed. In addition, because it was possible to control the exhaust gas temperature at the outlet of the auxiliary combustion chamber to about 850 degrees C and the exhaust gas temperature at the outlet of the quenching chamber to 200 degrees C or lower, the dioxins concentration at the outlet of the quenching chamber was reduced successfully to the targeted value or lower.

    The R and D project is implemented for manufacturing high-quality semiconductor crystalline materials of large size and uniform characteristics, in order to improve semiconductors as components for controlling power systems, and reduce power loss. The semiconductor melts, in particular silicon melt, is highly reactive, readily reacting with the atmosphere and crucible holding the melt, and it is difficult to collect their thermal properties. Therefore, an electro-magnetic levitation furnace working under a microgravity is used, to dispense with a crucible for measurement of their properties in the absence of thermal convection. The preliminary tests using the furnace produce surface tensions of the melts, because Ge is less reactive than silicon, stable in the form of a GeSbTe compound, and not wettable with Al{sub 2}O{sub 3}, MgO, SiO{sub 2} or Si{sub 3}N{sub 4}. The measurement of electric resistance of InSb indicates that InSb has characteristics of a semiconductor when it is solid and a metal when it is liquid, as is the case with Si. The program codes are developed by each researcher, and combined with each other to establish the comprehensive thermal flow analysis program, which includes all of the aspects of the internal CZ furnace structure for growing the crystals.

    The container and package recycling law is fully enforced starting fiscal 2000. Recycling obligation is placed also on plastic containers and packages discharged from households, excepting PET bottles for beverages and soy sauce. Therefore, it is required to establish an interim processing technology to process these materials into shapes easy for re-utilization and transportation, that is a technology to manufacture granules with adequate diameters. The purpose of this research is to develop the interim processing system technology. Design, fabrication and installation were performed on an interim processing system plant (a mixed waste plastic granule manufacturing facility) that can process annually waste plastics of 3,000 tons (0.5 t/h). The plant consists of the following four pieces of equipment: (1) a pulverizer, (2) a PVC sorting device, (3) a granulating device, and (4) a sizer. After the installed interim processing system demonstration plant has been trially operated and adjusted by each device, the whole plant was given the trial operation and adjustment to have verified that all the devices function normally. In addition, in order to evaluate economy of the waste plastics interim processing, the processing cost was calculated and the economic performance was evaluated preliminarily by using the rated electric power setting and trial operation data of each device.

    R and D was conducted concerning intermediate processing technology for recycling mixed waste plastics, a technology for processing household waste plastics such as plastic containers and packaging into plastic pellets of suitable grain sizes, with fiscal 2000 results compiled. In the development of the element technologies, an air clutch structure was added that generates rotor slip when foreign matters were engaged, thereby unnecessitating pre-sorting work for locating and removing metallic foreign matters. Addition of an air separator and a sieving machine also helped to achieve a useful-plastics recovery rate of 75% or more in the PVC separation equipment. In the operation of a demonstration plant, a continuous operation was carried out in a three-shift 24-hour system for five days, with the data obtained. Further, waste plastics to which the Containers and Packaging Recycling Law was applicable were treated, resulting in the processing capacity of 0.51 t/h and the production capacity of 0.38 t/h, which both exceeded the target. In the evaluation of the intermediate processing system, the cost of waste plastics treatment turned out to be about 50,000 yen per ton in the case of a plant having a processing capacity of 6,000 tons per year and about 30,000 yen per ton in the case of a plant of 24,000 tons per year.

    This paper reports the achievements in the Sunshine Project in fiscal 1988 in studies on the studies of the initial process in liquefaction. It is intended to identify the swelling phenomenon in coal particles in the coal slurry preparation and preheating processes, and change in the slurry viscosity associated with the heating. The slurry viscosity starts decreasing from around 300 degrees C at which the liquefying reaction begins, and decreases sharply at around 350 degrees C. Therefore, rise in the viscosity at temperatures below 300 degrees C is caused by factors other than the liquefying reaction. The rise starting at 100 to 120 degrees C is due to absorption of the solvent by coal. The rise starting at 210 to 260 degrees C requires further discussions. The equilibrium swelling ratio was measured on different types of coals by using the hydrogenated anthracene oil solvent. No coals swelled at 100 degrees C. The temperature of 200 degrees C largely divides coals into those swelling and those not swelling. At 300 degrees C, the coals were divided into those shrinking after largely swelling, those not swelling and those swelling monotonously. For consideration of the utilization as an auxiliary solvent, petroleum-based heavy oil was used to perform coal liquefaction to discuss effects of the solvent on the liquefaction rates. (NEDO)

    This report summarizes the fiscal 1996 development result on technology for creating advanced bio-affinity materials. The functionally gradient artificial tooth root with fine structure was fabricated by the following processes. The surface of a cylindrical Ti rod was first dry-jet-sprayed with ultrafine particles prepared by RF plasma, where its composition was changed continuously from Ti to alumina in a radial direction to form an FGM layer. The so-formed green composite was then sintered while heating the Ti side and alumina side at 1400K and 1800K, respectively. Compressive strength over 200MPa, durability of 10{sup 7} stress cycles at 1000N, and adhesion strength over 65MPa to substrates were obtained. As the outermost surface of the composite was coated with hydroxyapatite by plasma spraying, cell growth on the surface was confirmed without any contamination with heavy metals. This material is suitable for dental use in mechanical and chemical properties. Study was made on non- destructive analysis of FGM. A slant angle injection method was studied to increase the instrumental resolution power of Rutherford backscattering spectrometers. Composition modification was analyzed at a nm level quantitatively. Positron annihilation Doppler broadening was also measured. (NEDO)

    Discussions were given to reserve global environments on reducing dependence on fossil resources and more effectively utilizing wood resources. Economically utilizable amount of wastes from lumbering factories reaches about five million tons annually. Discussions were made on a ligno-bioprocess that uses these wastes. The current quantitative production efficiency of cellulase by means of bacterial breeding is very high. A problem is production of ligninolytic enzymes, to which application of the recombinant DNA method is indispensable. Combination of steam explosion with biological decomposition or the organosolv process is an effective method for lignin decomposition. Decomposition of cellulose by using the ultra critical water method is worth noticing. With respect to hemicellulose utilization, production of cellulose derivatives, biodegradable polymers and oligosaccharides would be conceivable by means of esterification and etherification. Vanillinic acid, adhesives, resins and lignin-based polymer materials could be manufactured from lignin. Material cost for these products accounts for about 35% of the product price, thus making the lignochemicals promising commercial products. 301 refs., 71 figs., 39 tabs.

In fiscal 1997, a novel mutagenesis technique was developed to obtain more kinds of mutational genes by shuffling between clonal genes as compared with the previous homogeneous recombination. A genotype- and phenotype-linking technology was developed by expressing random motifs (peptide as components of the active site of protein) on bacteria, and by developing a single-motif protein library. Study was made on a selection system for functional molecules of catalytic activities in a gene level, and a selection system for function of signal transduction. Analysis and evaluation study on vitro experimental technology can be efficiently promoted by recognizing the fitness landscape of target protein molecules. As a result, instead of the conventional method which needs several cycles of mutation and screening of 3-4 week/cycle, an efficient method possible to obtain multiple mutants was established.

    The R and D programs were implemented to develop techniques for creating members of high-melting metals, having a very high melting point and potentially excellent high-temperature strength characteristics. These are expected to replace Ni-based superalloys for gas turbine members, to further increase operating temperature of the turbine. The programs were aimed to improve their high-temperature strength and toughness and hence their reliability by microscopically controlling their compositions and structures, and also aimed to improve their durability by coating them with a film capable of preventing oxidation and resisting to gas-induced corrosion to impart resistance to oxidation and corrosion to them. For the design of Nb-based solid solution alloys, it is found that dissolution of Mo at around 30 at.% or less and W at 20 at.% or less in Nb improves their high-temperature strength and toughness. For the design of high-strength Nb-based composite materials, it is found that Si-containing Nb-based composite materials, prepared by mechanical alloying, are amorphous or present in the form of solid solution of Ni supersaturated with Si.

    This report summarizes the fiscal 1999 R and D result on technologies for creating bioaffinity molecules using submicron beads. By improving particle production, favorable SGNEGDE particles for drug fixation were produced on a scale 10 times as large as previous one. Various functional groups were obtained for particles immobilizing ligands. Magnetic purification was attempted by using new magnetic polymer particles. Synthesis of particle unsusceptible to non- specific bonds, and analysis of its modified surface properties were attempted. Reversible attachable-detachable surface coat was obtained by immobilizing boric acid to glycol group on affinity latex SG particles. The experiment result on affinity latex for detecting one-point mismatched DNAs showed the dependence of DNA hybridization on shearing resistance. To construct the library of new substances reacting with bio-receptors, solid phase synthesis of anti- tumor heterocyclic compounds was analyzed. The library of the pharmacology of new lead compound such as sugar moiety was also constructed. Study was made on attachment of alkaloid to a solid phase, synthetic reaction on a solid phase and library construction. (NEDO)

    For the creation of new industries and for their expansion to the consumer market, efforts are made to develop laser-aided technology of bonding titanium with other metals and CAD/CAM (computer-aided design/computer-aided manufacture)-aided technology of high-precision multidimensional laser machining for titanium. In the development of technology for bonding titanium and other metals, combinations of titanium and stainless steel and titanium and copper are examined, and a dissimilar metal joint is successfully manufactured, free of cracks at a tension shear strength level of approximately 4200N/40mm and shear stress of 200MPa or higher. In the study of the mechanism of bonding, it is found that a sound weld metal is created with the formation of intermetallic compounds well inhibited by allowing titanium to be on the upper surface. In the study of laser-aided titanium cutting, a dross-free cutting process is realized by optimizing cutting conditions such as those involving laser excitation and assist gas application. Three-dimensional laser-aided cutting is carried out in compliance with a 3-dimensional laser cutting program incorporating metal pattern data, and the process is found to reduce the number of necessary dies to 1/4 to shorten and simplify the process.

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

    It is intended to establish an energy saving type mass production technology to manufacture solar cell substrates by using the electromagnetic casting process. This paper describes the achievements in fiscal 1997. Preliminary experiments were performed for high-performance slicing processing and post-slicing rinsing to reduce the cost by enhancing productivity in the slicing process. Since there is a problem of mixing of contaminating raw materials due to diversification in raw materials, resistance and impurity concentration must be determined on each raw material as the materials for the Czochralski method. Then, the raw materials are sorted out referring to the determination results, and they can be used for the electromagnetic casting process upon optimizing them. As a result of having sliced an ingot of 15-cm square with a length of 40 cm by using a mass-production wire saw, an accuracy of 22.8 {mu}m was attained as intra-face variance when the required cutting time was 476 minutes and the substrate thickness is 348 {mu}, thus having obtained prospect for achieving the standard. Development was made on a water jetting rough cleaning machine to separate and remove slurries (oil and grinding particles) from the substrates after slicing, and an arm robot to accommodate substrates into cassettes, which provided processing velocity of 9 second per substrate. A problem of raising the speed remains to be solved. (NEDO)

    Research and development has been made with an objective to replace the electric discharge processing consuming a large amount of energy and having environmental load, with the cutting process consuming less energy while maintaining the equivalent processing precision. This paper summarizes the achievements in fiscal 2000. Development of cutting tools has made three times or more as many multi-aspect utilization as compared to conventional tools possible by researching the tip shapes. In addition, ultra hard end mill suitable for cutting very hard materials using an ultrasonic cutting head was fabricated on the trial basis, and its cutting capability was verified. In developing the cutting processing heard, a vibration mode possible of cutting with the ultra hard tool was generated, ATC has become possible, and the possibility of cutting hard-to-cut materials was verified. For processing a narrow and deep part, an improved type tool was developed, whereas the practical cutting performance suppressing wear of the blade tip was obtained. To deal with the environment, development and prototype fabrication were performed on a unit having a grease lubricated high-speed main shaft that is considered to be the mainstream in the future. In the operation test at 20,000 min-L, know-how was acquired in relation with the basic performance, manufacture and use of the unit. (NEDO)

    Discussions were given on manufacture of raw material silicon for solar cells with regard to boron removal, solidification, finishing and refining of metallic impurities, refining of unutilized silicon scraps, and making them into wafers and solar cells after refining. This paper summarizes the achievements in fiscal 1999. With regard to purity deterioration due to contamination by boron containing silica powder generated during the boron removal in the manufacturing process, the facilities were modified resulting in the reduction thereof to 0.04 ppmw or less. Regarding the repetitive use of boron removing crucibles, the experiment identified the possibility of using them for more than three times. In trial fabrication of samples by using the solidification refining and cast integrated process, ingots of 550 mm square and about 300 mm high were obtained, which were sliced into 10-cm square materials for use as wafers. Measurement of the conversion efficiency has resulted in 13% or more which is almost equivalent in the center and edges of the ingot. It was revealed that solar cell wafers may be fabricated by using this process, which can use either the p-type low-resistance silicon scraps or the metallic silicon as the starting material. (NEDO)

    This paper describes the achievement in fiscal 1997 of analyzing practical application of a technology to manufacture solar cell silicon raw materials. Silicon consumption for solar cells in fiscal 1997 has increased to 2000-ton level, and the supply has been very tight. For drastic improvement in the demand and supply situation, development of SOG-Si manufacturing technology and its early practical application are desired. The development of the NEDO mass-production technology using melting and refining has completed constructing the process facilities in fiscal 1998, and will enter the stage of operational research. However, insufficiency in the basic data about behavior of impurities is inhibiting the development. In the substrate manufacturing technology, discussions have shown progress on use of diversifying silicons outside the standard by using the electromagnetic casting process. For slicing and processing the substrates, development of a high-performance slicing equipment and automatic rough rinsing machine is under way. Properties required on silicon raw materials vary considerably widely because of difference in cell making systems and conditions, which is attributable to unknown impurity behavior. When 1GW production is assumed, the cell module manufacturing cost is calculated as 137 yen/W, for which low-cost mass production for its realization, slicing productivity enhancement, and cost reduction are required. The paper also describes site surveys in overseas countries. (NEDO)

    Described herein are the FY 2000 results of development of cluster ion beams. This technology generates the strong ion beams of atom and molecule clusters, and irradiate them onto the solid surfaces, to create new materials or treat materials. It allows the nano-level treatment. The program for high-current cluster ion beam generation/irradiation technology for industrial purposes attains the target high-current beam of 500{mu}m. It is necessary to establish the optimum cluster size, irradiated energy and ion species for the highly functional surface treatment, for which applicable technologies, e.g., those related to time of flight and molecular dynamics, are developed. Studies on high-current, large-area irradiation technologies are started. The program for material processing technologies involves evaluation of crystalline defects formed during the beam implantation by photoluminescence spectroscopy, and studies on semiconductor surface processing technologies. The surface smoothening technology is investigated to reduce crystalline defects and stress-induced strains for difficult-to-process materials, e.g., SiC and diamond, and the good results are produced. The program for development of superflat/superhard thin film formation technology involves irradiation of the Ar ion beams during the deposition of C{sub 60}(fullerene), to produce the superhard thin film.

    In order to manufacture silicon for solar cells, development is intended on a technology to manufacture silicon (SOG-Si) for solar cells by means of metallurgical methods using metallic silicon with purity generally available as an interim starting material. The silicon is required of p-type electric conductivity characteristics with specific resistance of 0.5 to 1.5 ohm per cm, to be sufficient even with 6-7N as compared to silicon for semiconductors (11-N), and to be low in cost. While the NEDO fluid bed process and the metallurgical NEDO direct reduction process have been developed based on the technology to manufacture silicon for semiconductors, the basic policy was established to develop a new manufacturing method using commercially available high-purity metallic silicon as an interim starting material, with an objective to achieve cost as low as capable of responding to small-quantity phase production for proliferation purpose. Removal of boron and phosphor has been the main issue in the development, whereas SOG-Si was manufactured in a laboratory scale by combining with the conventional component technologies in fiscal 1991 and 1992. The scale was expanded to 20 kg since fiscal 1993, and a five year plan starting fiscal 1996 was decided to develop the technology for industrial scale. Fiscal 1997 has promoted the development by using the 20-kg scale device, and introduced facilities to develop technology for mass-production scale. (NEDO)

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

    An energy-efficient forming technology is developed for heat-resistant hard materials which are difficult to cut and demand much energy for their precision forming. It is hoped that a material Hv1000 in hardness if obtained will enable the manufacture of cutting tools for use under severe conditions. Under the circumstances, a material based on Fe-4.5%Mo-1.5%V-3%Cr is produced with high reproducibility, where a carbide dispersion carburization (CDC) method (vacuum carburization at 1,040 degrees C, second quenching at 800-850 degrees C, and tempering at 160 degrees C) is employed for realizing a very fine structure. This as the tip is combined with the tool, which is then tested for abrasion. As compared with the control material, it is found that the abrasion of the new material is but 33% of that of the control material. Studies are under way for a commercially acceptable constitution which will exhibit Hv1000 after heat treatment and for conditions of CDC treatment. An intermetallic compound TiAlCr, to be obtained by a process of mechanical alloying and pulse discharge sintering, is found to be superplastic. An automobile engine valve is manufactured by an extrusion process and by near-net shape forming, cutting, and grinding. In the manufacture of tungsten bonded ion gun parts by the pulse discharge sintering method, sufficiently high strength is obtained. (NEDO)

    In the proliferation stage of solar cells, a technology is required to manufacture low-cost SOG-Si that can handle small quantity production. Development is being made on a manufacturing technology using high purity metallic silicon (99.5%) as the raw material. Considering that the subject impurities are P, B and metallic impurities (Fe, Ti and Al), a manufacturing method consisting of the following processes is being developed: metallic silicon/phosphorus removal, solidification and rough refining/boron removal, solidification and fine refining. Discussions are being advanced on phosphorus removal by using a large electron beam fusion equipment, and at the same time, the discussions are supported by fabricating and installing a large equipment intended of removing boron and the metallic impurities. Boron is removed by oxidizing it with steam. Therefore, the basic mechanism of the equipment is to spray argon plasma added with steam onto the molten silicon surface. In boron removal, diffusion of boron onto the reaction interface in the primary reaction determines the rate. A boron removal rate for B/10 to 0.1 ppm of 45 kg/h as maximum was achieved. The derived silicon has met the requirement. (NEDO)

    The paper described multi-stimuli-responsive materials out of the technology developments for creating original high-functional materials under the system of R and D of industrial scientific technologies. These are materials which repeatedly reproduce functions such as separation, penetration and movement in response to stimuli by imitating living organisms. In relation to polymer multi-stimuli-responsive materials, various copolymers were synthesized using N-acetyl (meta) acrylamide, of which the synthesis method was established in the previous fiscal year, as a main component, and thermal responsive polymer with upper critical solution temperature which becomes a base of separation functional materials was searched for. By immobilizing it with molecular recognition ligand, measured was thermal dependence of affinity of the immobilized matter to albumin. Also studied were molecular recognition cell adhesion/separation functional materials. Concerning composite multi-stimuli-responsive materials, with the use of silica microcapsule surface-immobilized with silane coupling agent, studied were the optimum conditions for immobilizing thermo-responsive polymer to the surface of the capsule. Using motion functional materials by ion exchange resin, obtained was motion functionality which is satisfactory at the state of practical use. 94 refs., 82 figs., 16 tabs.

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

    This research aims to prepare conceptual designs for a 250t/d-class and 500t/d-class coal liquefaction pilot plants based on the achievement of research on solvent extraction liquefaction of coal. It also aims to define the solvent extraction process and provide decision-making material relative to the development and promotion of coal liquefaction technologies in the future. Development started in 1978 of the technology of solvent extraction liquefaction of coal, and a 1t/d PDU (process development unit) was completed in 1981. Studies through its operation have continued for more than 3000 hours already, and technical data are being accumulated steadily. Techniques acquired through operating the 1t/d PDU have been put together, and rough process conditions are established. A rough process result is achieved of the same conditions. In these two respects, the newly developed process is equal to other processes. The phenomena in this process are roughly grasped. It is deemed that, with the existing technique combined with the technique acquired here, a technological level has been reached where conceptual designs of large pilot plants may be worked out for solvent extraction liquefaction of coal. Under the circumstances, with a view to developing a commercial plant whose main products will be fuel oils, conceptual designs are prepared for large pilot plants, and are compiled into this report.

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

    This paper describes the achievements in fiscal 1999 on developing a screening test method with high accuracy for internal secretion disturbing substances. Development was made in cooperation with the OECD on the screening method that uses as a parameter whether a chemical substance has a hormone-like activity. For the womb breeding assay method to evaluate a feminine hormone-like activity, a reproducibility and comparison test was performed on womb breeding in immature rats administered with ethinylestradiol, the administration routes, and animals used (young and weak rats, and rats whose ovaries have been extracted). In order to evaluate a masculine hormone-like activity, the basic data were collected to develop the Hershberger method, and participation was made in the OECD verification tests. Discussions were given on comparison on castrated and non-castrated rats when 17 {alpha}-methyltestosterone was administered, the administration period of time and reproducibility when immature rats were used. The Hershberger method reactivity was discussed on rats relative to estrogen. In a toxicity test using 28-day repetitive administration, bisphenol A gave impacts on the kidney, the stomach and intestine tubes. (NEDO)

    Research and development was carried out for the establishment and commercialization of the technical seeds of a newly proposed 'parallel grinding type aspheric surface grinding method,' based on the results of studies of ultra-accuracy grinding and aspheric surface machining technologies conducted at Tohoku University. The new method is characterized in that a work point on the work piece faces the grinding point on the grindstone cross section on the one-to-one basis because the grinding point travels on the grindstone cross section. Accordingly, the method is quite suitable for corrective grinding for eliminating only the error in case a geometrical error occurs on the wrought surface. For this purpose, measurement of the machine surface on board the machine is indispensable. Hence: a study of corrective grinding methods under an on-board measuring system. As the result, the initially intended geometrical accuracy level was attained in the machining of axis-symmetric aspheric glass lenses and aspheric metal molds, and coarseness on the finished surface in the grinding of glass lenses was reduced to 0.3{mu}m using a diamond grindstone. In conclusion, machining accuracy and finished surface coarseness were remarkably improved, and this enables machining without the need of polishing and demonstrates that there are possibilities of commercialization.

    This paper describes the achievements in fiscal 1999 on development of the technology to create biological bonding substances utilizing particulates. In fixing ligands onto particulates, it is necessary that various compounds be fixed with their receptor bonding specificity maintained. Therefore, carboxylic acid, thiol and bromoacetyl groups were introduced into the particulates. Capping them by using methoxyacetyl was found capable of suppressing non-specific adsorption. Opioid compounds were synthesized for their fixation onto particulates for selection and separation. Carrying particulate bonding precursors in latex beads was realized. Synthesis will continue on opiod compounds in which amide groups are introduced into different positions to provide the particulate carrying ligands with diversity. Biological receptors for different compounds were obtained and refined by using compound fixing particulates. Refinement and acquisition were possible on FK506 bonded protein in a short time from cell extraction liquid by using the fixing particulates for the FK506 bonded protein. The paper also describes analysis of bonded domains, and position-specific fixation of the biological receptors. (NEDO)

    Research and development has been performed with an objective to reduce discharge of dioxins in aluminum product manufacturing processes. With regard to the quantity of chlorine used in aluminum molten metal refining process, the refining tests using 100% chlorine gas and the mixed gas (nitrogen gas mixed at 80%) revealed that either gas has approximately the same degassing performance, and the use of the mixed gas can reduce the amount of chlorine used. Dioxin concentrations in the gas discharged from the refining process were measured under the refining condition using less amount of chlorine. As a result, it was verified that, in the case of using 20% chlorine gas plus 80% nitrogen gas, the concentrations of dioxins decrease to about l/6, or 0.6 ng-TEQ/N{sup 3}. The studies on suppressing the discharge of dioxins from the facility to wash chlorine treatment exhaust gas discovered that dioxin concentration in the scrubber circulating solution can be suppressed to 1/10 or less by means of gravity precipitation and separation of the suspended liquid. It was also made clear that pH should preferably be controlled to 10.5 to separate suspended substances from the precipitated solution. (NEDO)

Robot technologies for flexible, robotized manufacturing lines will be established, and robotization will be promoted in industries related with transportation equipment and semiconductor in and near Kumamoto City. Optimization is to be achieved in such processes as IC chip insertion so that piston insertion into a cylinder with but an extremely little gap between them will be performed without scratches on the cylinder walls and that no plastic deformation will occur in the initial lack of positional correspondence. The technological tasks to be carried out include position detection based on visual information and skill making up, micro-force sensor of great precision and flexible force control, coordinated control of different types of robots, flexible handling mechanism, and integration of different techniques based on an information management system. The control of force now being exercised by humans will be reviewed from a new point of view and harmonization will be established between the human endeavor and sensing devices. Conceptual designs will be completed by the fiscal year end, with efforts concentrated on two prototypes, one for assembly lines and the other for IC inspection. (NEDO)

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

    Collected in this report are the results of efforts of the Government Industrial Research Institute, Osaka, in the 7-year period that began in fiscal 1974. The Institute, after looking for basic reactions in thermochemical cycles which are promising, has come to propose a new cycle in which iron and bromine are the reactants. In the research, the Fe-Br reaction is divided into a hydrogen generating loop and an oxygen generating loop, both to be developed into devices. Problems in developing them into a cycle are isolated, and solved. In the hydrogen generating loop, the use of a molten salt is contrived for the prevention of reduction in the reactivity of the Fe{sub 3}O{sub 4} to be generated, and now it is expected that the problem will be solved. No problem is detected in the oxygen generating loop. The process is now accepted as a superb one. As for the materials for the Fe-Br-based cycle apparatus, important tasks have to be undertaken since existing materials cannot be used as is. Besides, thermal efficiency etc. are estimated for a new As-Br-based hybrid cycle and the Fe-Br-based cycle. (NEDO)

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

    In relation to considerations on composition of gas produced by coal gasification, the HYCOL hydrogen generation process data were analyzed. From the fact that CO concentration (Y) decreases linearly with CO2 concentration (X), element balance of gasification of reacted coal was used to introduce a reaction analysis equation. The equation includes a term of oxygen excess {Delta}(amount of oxygen consumed for combustion of CO and H2 in excess of the theoretical amount), derived by subtracting the stoichiometric oxygen amount used to gasify coal into CO and H2 from the consumed oxygen amount. The {Delta} can be used as a reference to oxygen utilization efficiency. An equation for the {Delta} was introduced. Also introduced was a term for steam decomposition amount derived by subtracting the generated steam from the supplied steam. These terms may be used as a clue to permeate into the gasifying reaction process. This suggestion was discussed by applying the terms to gas composition value during operation. According to the HYCOL analysis, when a gasification furnace is operated at higher than the reference oxygen amount, coal supply variation is directly reflected to the combustion reaction, making the {Delta} distribution larger. In an inverse case, unreacted carbon remains in the furnace due to oxygen shortage, and shift reaction may occur more easily even if oxygen/coal supply ratio varies. 6 figs., 1 ref.

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

    Described herein are results of survey on brown coal liquefaction techniques and peripheral techniques, centered by COSTEAM process under development in USA, solubilization by alcohol and liquefaction and cracking with the aid of tetrahydroquinoline as the hydrogen donor under development in Japan, and low-temperature carbonization and new promising techniques. The COSTEAM process shows higher reaction rates, conversions and oil yields for brown coal liquefaction than the one using hydrogen gas. Some of the problems involved in this process high viscosity and oxygenated compound content of the product oil. The product oil is acceptable as fuel for power generating plants and can be produced at a moderate cost, but may be unsuitable as vehicle fuel. Coal liquefaction and solubilization processes are mainly represented by those which use hydrogen. The hydrogen cost, which is high, determines the product price. The processes which use alcohol or tetrahydroquinoline are still in the experimental stage. (NEDO)

    This paper looks back the history of applications of laser processing in the automobile industry, and introduces contents of some particularly unique applications from among them. The CO2 laser and YAG laser that are used mainly have increased their outputs with the times, and 50-kW CO2 laser and 4-kW YAG laser have now become available commercially. The laser processing has become used widely for cutting purpose in Japan, which is in contrast with their high application to welding in Europe and America. Cutting thick plates has been developed recently, which is applicable to plates as thick as about 25 mm. A flexible system in which YAG laser is combined with an optical fiber/articulated robot is operating for three-dimensional shape processing. Automobile makers are adopting laser processing for welding in place of the electron beam welding that has been used conventionally. The process is used also for a number of other applications including surface reformation, such as surface quenching for cylinder liner, and valve seat padding. 8 refs., 8 figs.

    Sludge generating in a sewage treatment plant is disposed through the processes such as concentration, dehydration, and incineration in sludge disposal facilities. In recent years, there has been a trend that this sludge increases in volume as well as worsens in the concentration. A case is predictable where the sludge load to the dehydrating process is so large that the sludge can no longer be processed in sufficient quantity. In the meantime, if sludge is ozone-treated, viscous substance on the surface of sludge particles can be separated with a comparatively small amount of ozone, with sludge concentration enhanced. At Meidensha, an experimental plant was set up for the ozone treatment of sludge in a sludge intensive treatment plant of a metropolis, with a verification experiment carried out for a sludge concentration improving system by ozone. As a result of comparison of the treatment performance between an assessment system for performing ozone treatment and a reference system for not performing, the average value of the sludge concentration of a gravity concentration tank was 1.9% of the reference system against 1.7% of the assessment system in a continuous treatment experiment in the summer, while the solid collection ratio was 65.8% of the reference system against 95.5% of the assessment system, enabling a superior improving effect to be obtained.

    Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

    This paper describes the achievements in the Sunshine Project in fiscal 1981 in development of a solvolysis liquefaction plant. The solvolysis process is characterized by performing the first stage reaction (liquefaction) in a short time by using hydrogenated heavy solvent produced spontaneously in the process. This short-time liquefaction reaction was carried out continuously by using a 1-t/d experimental plant, and a prospect was obtained on smooth operation and realization of the device. A test using a testing device allowing the temperature to rise within several minutes was performed on the effectiveness of a hydrogenated coal based heavy solvent (fractions of a hydrogenated heavy anthracene as a model) as a study on the first stage reaction. Partially hydrogenated materials of polycyclic condensed aromatics in the heavy solvent is largely involved in the initial reaction. In the solid-liquid separation, solids and heavy fractions are selected and removed from the first stage reaction products, and the light fraction is supplied into the second stage reaction (hydrogenation). The solvent deliming process was tested by using a batch type solid-liquid separator, whose effectiveness was verified. Studies were performed by using Australian sub-bituminous coal on operation of a continuous operation device consisted of systems for the first stage reaction (liquefaction), solid-liquid separation, second stage reaction (hydrogenation), and solvent circulation.

Basic facilities were completed by giving expansion constructions on the extraction reaction column, gas-liquid separation column, and hydrogenation reaction column. The operation was performed with the primary object placed on verifying the effect of measures on problems that have been extracted, and checking the solvent balance. The conversion rate at an extraction reaction temperature of 450 degrees C was 83%, agreeing with the result of the fundamental study. The solvent has turned light as a result of 153-hour continuous operation, but circulating use was possible. Progress of the reaction has become easily controllable in the hydrogenation system. Fundamental discussions were given on engineering aspects, which require further accumulation of data. In the research of the solvent extraction and liquefaction process, fiscal 1981 has performed discussions on liquefaction catalysts, and on the effect of the hydrogen donating solvents.

    For the functional upgrading of electronic equipment which will support the computerized society in the 21st century, a substance itself is required to exhibit novel functions or to behave better on a reduced amount. Dependence on the synthesis of new materials alone has its own limit, but a method of reducing the substances conventionally known for their safety into particles of the nanometer scale will be one of the solutions. Micro-science and micro-technology are in progress in Japan and abroad, which mainly deal with particles 10nm-100nm in size. To make better use of the functions of substances, there should be single nanoparticles 1nm-10nm in size. Such particles are easy to coagulate, however, and it is difficult to keep them in their nanometer-scale single state free of coagulation. If Japan succeeds in the development of 1nm-10nm size nanoparticle structurizing technology and manufacturing technology utilizing this technology, Japan will have a clear advantage over other countries in the world in the domain of nanoparticle engineering. The survey and research described in this report aim to review the trends of technologies for nanoparticle composition and functionalization and to clarify the course that Japan is to follow in the development of technologies concerned.

    Described herein are results of literature survey on brown coal liquefaction reactions and elementary techniques. Liquefaction of brown coal in the presence of CO and steam, or CO, H{sub 2} and steam has been investigated. It is not clear by the literature survey whether it is superior to the normal process which uses hydrogen. Brown coal contains moisture at high contents, and the drying techniques are necessary to be developed for its liquefaction. The future coal liquefaction plant will be much larger than the past one, and there are a number of problems to be solved, such as those involved in the designs of large-sized high-pressure slurry pumps, heat exchangers and preheaters. It is also necessary to develop the materials of and production techniques for large reactors which are serviceable under severe conditions. The solid-liquid separation for liquefaction products involves a number of the elementary techniques characteristic of coal liquefaction processes, and needs many technological developments. The one-stage brown coal liquefaction process is compared with the two-stage process for the secondary hydrogenation of SCR, but no clear conclusions are reached. (NEDO)

    In order to apply FEM (finite element method) flow analysis to environmental engineering, the two-dimensional analysis system was developed, and applied to the design of plant ventilation and improvement of an enviromental control equipment. Furthermore, the three-dimensional analysis system was developed to extend its application. Since in a large scale model, no enhancement of a processing capacity was expected even by a supercomputer because of longer I/O times between internal and external memories caused by a small internal memory space, the parallel processing system with multiple external memories was introduced to analyze such models. To achieve more efficient processing, multiple series of renumbering codes were also prepared to optimize the processing order of solvers, elements and nodes. As examples, the improvement of a thermal oxidizer and the ventilation design for a forging plant, and as an example of a three-dimensional large scale model, the flow analysis around a plant were presented. 8 refs., 17 figs., 1 tab.

    This paper describes the measurement and analysis for clarifying solution structure of supercritical water and exhibition mechanism of solvent functions. It also describes the development of new processes using supercritical water as reaction solvent. The PVT measurements were conducted in the supercritical region using pure water and NaCl aqueous solution, to confirm the reduction of molar volume of the electrolyte solution. The hydration structure was examined in the supercritical aqueous solution by the molecular dynamic simulation. As a result, presence of hydrogen bond structure, where the contribution of two branching hydrogen bond can not be ignored, was suggested under the supercritical condition. Characteristics of supercritical aqueous solutions are analyzed through in-situ Raman and scattered X-ray spectral measurements. Moreover, this paper introduces developments of some processes in the supercritical water, such as decomposition of wasted polymers, recovery of chemical materials, reforming of heavy hydrocarbons by contact hydrogenation, and synthesis of fine powders of metal oxide by reaction crystallization.

    For the establishment of the basis of supercritical fluid technology, we perform elucidation of the specific feature of the supercritical fluid as a reaction media and development of some new process. In this study, we first studied the fluid structure of SCF through in-situ spectroscopy and MD simulation. As a result, significant hydrogen bonding amongst water molecules and a solvation structure around the solute were observed in the supercritical state. This fluid structure has new features different from that of high temperature steam or liquid water. We found that this is closely related to the difference of bulk properties of SCF and local one around the solute. On the basis of these fundamental findings and with the better understanding of the specific features of SCF as a reaction media, development of some new process had been conducted more efficiently and successfully. The processes being developed in this study include 1) waste biomass and plastic conversion to recover chemicals, 2) hydrogenation of heavy oil for desulphurization through partial oxidation 1 and 3) hydrothermal synthesis of metal oxide fine particles.

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

    A bio-reaction of microbes (catalytic reaction by an enzyme) is characterized in that the reaction is carried out at a normal temperature and under a normal pressure and has particularly high specificity with respect to substrate (reactant). It is considered that a low loading process of environment harmony type can be constructed by applying the bio-reaction in petroleum refinery process. CO{sub 2} exhaust and energy consumption in the bio-desulfurization (BDS) is estimated to be 70 to 80% lower than those in hydrodesulfurization (HDS). The bio-technologies that can be applied to the petroleum refinery process include, for example, desulfurization, demetallation, dewaxing, denitration, cracking and so on. In this paper, the present state of bio-desulphurization technology is introduced.

    Investigation has been made on the current status of food sanitation controlling technologies. Eighty percent of food poisoning is caused by bacte such as Salmonera, enteritis vibrio, staphylococcus, and pathogenic colibacillus. Putrefaction as the cause for food poisoning occurs from proliferation of different microorganisms. Heating sterilization is the main method being performed, but non-heating method may include sterilization by flash and high voltage pulse discharge in addition to ultra-high pressure and ultraviolet ray sterilization. As a result of the questionnaire survey, what is extracted as the problems in the food sanitation controlling technologies is to establish a rinsing and sterilizing method with large sterilization effect, an effective sterilizing method and thawing of processed marine products, and a cooling method in food processing. Increasingly demanded for the future is to develop a foodstuff sanitation control system using as the core the hazard analysis critical control point (HACCP, a quality control program developed by the U.S. NASA to ensure safety in manufacturing space food), and micro-organism control and sterilizing technologies to support the above system. The flash pulse and high-voltage pulse sterilizing technologies as the non-heating sterilizing technology are more effective than the conventional heating sterilization methods also from the aspect of quality retention after sterilization. More active development thereof is desired. (NEDO)

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

    Measures against Cryptosporidium parvum (C. parvum) in the waterworks are discussed. C. parvum is a pathogenic protozoan, and exists in the form of oocyst protected by a hard shell. It does not multiply in water or food, but does in human intestines and causes violent diarrhea and bellyache. A grave concern was created when many people were infected with the protozoan via tap water in Japan and the United States. Under such circumstances, ozone is used in an experiment to inactivate C. parvum. It is found that the C. parvum oocyst inactivation effect is evaluated by using a Ct value (disinfectant concentration Cmg/Ltimescontact time in minute) and that ozone treatment inactivates 90-99% of the protozoan. When various advanced water treatment technologies are being introduced for the purpose of serving safe and tasty water, the outcome of this study conveniently offers an ozone treatment method that will additionally inactivate pathogenic protozoa. Studies will be continued to elucidate the effects of factors of ozone treatment and water quality for the completion of an ideal disinfection process.

    Conditions for creating Japan`s type technologies have been investigated by extracting technologies and experiences meriting the succession to the next generation among the industrial technologies in Japan after World War II. Technological creativity of Japan began to appear from the 1970`s. Quartz watch of SEIKO, U-Matic VTR of SONY, ladle refinery method of DAIDO Steel, PAN-based carbon fiber of TORAY, continuous annealing of Nippon Steel, calculating machine using liquid crystal of SHARP, ASA-400 high sensitivity film of FUJI FILM, and Japanese word-processor of TOSHIBA are the examples. The basic ability to create those products and technology lays in the diversity of firms in electronic device and fine machinery industries consisting the boundary between general and electrical machinery, the systematizing ability and inter-industrial cooperation which were promoted through quality control, automatization of assembly and production control by computer, and the research and development capability which has been brought up during the high economic growth as a learning process of technology. The society and industries have to make efforts to create the new creative conditions for younger generations. Otherwise, Japan`s technology will not develop. 134 refs., 19 figs., 8 tabs.

The solar power generation shifted from the thermal power generation to the light power generation. There is also a method to use solar heat directly. As to power systems and the distribution of electric power, the subjects are a combination of energy source, geographical energy transportation, and heightening of consumption efficiency. It was indicated that the subjects changed with a lapse of time under technical/social/systematical conditions, and under the developable energy amount prescribed by those conditions. Heightening of efficiency, which can be realized even by a paper simulation, was realized partly helped by the developing measuring technology. The environmental problem becomes historically severe as a condition of the technical development. However, aimed at was the process where discharged matters and by-products are effectively used and disused matters are not produced. In the coal-thermal power generation, for example, a load of flue gas purification was reduced by the conversion to LNG. 253 refs., 65 figs., 12 tabs.

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a semiconductor equipment field, viewing until 5-10 years after. For the future semiconductor industry, the favorable cycling of creation of new demands through performance improvement, and further technology innovation through market expansion is essential absolutely. Since technology development is followed by investment, not only the performance of each equipment but also the higher productivity and cost balance of the whole factory are essential. Self-intelligent function and networking are thus necessary for the equipment. As measures for environment preservation and energy saving, such innovative technologies are required as recycling, reuse, reaction process improvement and alternative technology. Because of diverse final products and a short life time of products, a large-scale collective investment is becoming difficult. A mini-line sequential investment production system according to demand scales is under investigation. Some issues such as micro-technology, realization of 300mm wafer, modularization, CIM, reliability and standardization are also described. (NEDO)

    This paper describes the removal technique of gases such as CO2, SO2 and NOx which have the deep relation to the maintenance of global environment. This paper describes partially r SO2 and NOx which are the primary cause of acid rain. As for the removal of CO2 generated from fixed sources (thermal power stations and others), the separation technique and isolation-fixation technique have been researched on and developed. Of the separation method, the effect of the chemical absorption method and the adsorption method is proved with the preceding experiments. The isolation method is differently researched on as to store under deep sea or ground but may be urgent and temporary. The fixation of CO2 is a serious global problem which relates to the afforestation and forests. The fixation which uses coral reefs in ocean as the absorption source has a potential. As for the processing of substances causing acid rain, the desulfurization from petroleum and the flue gas desulfurization have the excellent results. The improvement of combustion method or the flue gas denitrification at the fixed sources are used to remove NOx. The removal of NOx from all diesel cars is difficult compared with the exhaust gas cleaning of gasoline cars and is not commercialized. 11 refs., 1 fig., 2 tabs.

    Researches have been made to increase density of 200,000-kW class generator and to increase capacity of 600,000-kW class generator necessary for putting superconducting generator into practical use. This paper summarizes the achievements in fiscal 2000. In the study of increasing densities of superconductors and field windings, strands were fabricated, in which aging heat treatment conditions, number of aging, and processing degrees between each aging were varied, to increase the critical current of Nb-Ti strand, wherein as high critical current as corresponding to about 90% of the target was obtained. Possibility of increasing the critical current with the final processing degree in the range of 4 to 5 was verified from the relationship between the final processing degree and the critical current. In the study of increasing capacities of superconductors and field windings, findings were acquired on enhancement of conductor stability and reduction in AC loss, with regard to superconductor strands well balanced in the two elements. Prospects were obtained in achieving the AC loss of 200 kW/m{sup 3} in the targeted superconductor. The residual resistance ratio was found to be 200, showing sufficiently high value, and sufficient function was verified in the stabilized copper. In the research of design technologies, primary basic design was performed. (NEDO)

    Survey was made on the trend of R and D on photonics engineering to clarify the direction of its impact and ripple effect on industrial fields. Reduction of environment burden, improvement of the productivity and reliability of products, and creation of new industries by novel creative R and D are necessary simultaneously. For reconsideration of the previous measurement and machining technologies in a manufacturing industry, use of photon (laser) beams is promising. As photonics engineering, photonics measurement and machining, and elemental and peripheral technologies for generation and control of photon were surveyed. Photonics application technologies for medical care and diagnosis, communication and transmission, entertainment, and chemical fields were also surveyed. In fiscal 1997 as the first year of this project, based on the results obtained in leading researches conducted until fiscal 1996, some technological issues were clarified through the survey on the latest trend of photonics engineering in measurement, machining and generation fields, and its feasibility in the other fields. 265 refs., 91 figs., 10 tabs.

    Trimming was performed and studied by cutting KFRP, an epoxy matrix with Kevlar fiber woven thereinto, using various laser beams. The CO2 laser is capable of high-speed cutting but the product is low in quality. The surface of a cut by the YAG laser is not high in quality even with its peak output elevated. The thermally affected area is smaller under the excimer laser but it is low in cutting speed. The ablation properties of the excimer laser were investigated and the beam was shaped into a linear beam for another experiment, but it failed to attain the target speed of cutting. Next, a combination of excimer laser and CO2 laser was used for cutting. It was so designed that the preceding CO2 laser cuts the KFRP at a high speed to leave behind a carbonized layer, which is followed by a linear beam which vaporizes the carbonized layer for removal. An optical system is adopted for reshaping the excimer oscillated beam into a tube-like beam. Optical conditions were determined for a fluence value required for the removal of the carbonized layer. When the CO2 laser was set at 160W and the excimer laser at 20W, a 1mm-thick sheet was successfully cut at a speed of 16.7mm/sec. 3 refs., 7 figs.

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

    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)

    As a part of the project for internationalization of coal liquefaction technology, this paper reported on the potential survey for location of Indonesian low grade coal liquefaction (study of applicability of the improved BCL process and survey of hydrogen production technology using coal gasification). The survey was conducted of a locational possibility of a coal liquefaction commercial plant to be located at mine site in South Sumatra for Banko coal raw material. The improved BCL process was applied in which the results of the study by NBCL Takasago Research Institute were reflected. Further, the hydrogen production was studied by gasification of Banko coal, and the comparison was made with the conventional natural gas reforming method. As a result of the study using information/knowledge obtained during the conceptual design of Australian brown coal, the construction cost of commercial scale liquefaction plant with the Banko coal processing amount of 30,000 tons/day became 549.8 billion yen in the case of using natural gas as raw material for hydrogen production. This construction cost is the lowest as compared with 601.7 billion yen in the demonstrative BCL process and with 577.1 billion yen in the advanced BCL process. This is a process making use of features of Banko coal. The process for hydrogen production by the steam reforming method using natural gas has an advantage of increasing the production amount of coal-derived liquid the most of the three other methods.

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)

    Surveys and studies were conducted to establish a practical SNG (substitute natural gas) production process. The hydrogasification process that Japan should develop is a flexible process that operates on the three modes of the maximum SNG yield, the maximum heat efficiency, and the maximum BTX (benzene, toluene, xylene) yield. Such being the case, an ARCH (advanced rapid coal hydrogasification) process was proposed, provided with a reactor capable of an ARCH-1 type operation for the maximum gas cooling efficiency and an ARCH-2 type operation for the maximum liquid yield. As for the details of the ARCH process development, the time and priority for development were determined for each of the items in consideration of the technical contents and the steps of development in the flow from a bench plant to a demonstration plant. The technology of char cooling and extraction was specified as the first item to be immediately dealt with. As for the development of the hydrogasification reactor, it was concluded that it was suitable to begin with the development of an injector. According to the development plan, the cost required up to a pilot plant test was estimated at 2 billion yen. (NEDO)

In an effort to develop a reactor, the current status was studied and future tasks were extracted concerning the one-through type and the internal circulation type entrained bed hydrogasification furnaces. In the study of practical application of the coal hydrogasification process, it was found that gas cooling efficiency would be increased from last fiscal year's 75.2% to approximately 78% by optimizing the process configuration. An ARCH (advanced rapid coal hydrogasification) process to have a novel reactor was proposed, and, for its commercialization, guidelines for dimensionally enlarging the process were worked out and tasks to discharge at each of the development stages were extracted. Relative to pilot tests, an efficient development program was deliberated, in particular, which comprised ARCH-1 and ARCH-2. (NEDO)

    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)

    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)

    A CWM manufacturing technology was developed by means of upgrading low rank coals. Even though some low rank coals have such advantages as low ash, low sulfur and high volatile matter content, many of them are merely used on a small scale in areas near the mine-mouths because of high moisture content, low calorification and high ignitability. Therefore, discussions were given on a coal fuel manufacturing technology by which coal will be irreversibly dehydrated with as much volatile matters as possible remaining in the coal, and the coal is made high-concentration CWM, thus the coal can be safely transported and stored. The technology uses a method to treat coal with hot water under high pressure and dry it with hot water. The method performs not only removal of water, but also irreversible dehydration without losing volatile matters by decomposing hydrophilic groups on surface and blocking micro pores with volatile matters in the coal (wax and tar). The upgrading effect was verified by processing coals in a pilot plant, which derived greater calorification and higher concentration CWM than with the conventional processes. A CWM combustion test proved lower NOx, lower SOx and higher combustion rate than for bituminous coal. The ash content was also found lower. This process suits a Texaco-type gasification furnace. For a production scale of three million tons a year, the production cost is lower by 2 yen per 10 {sup 3} kcal than for heavy oil with the same sulfur content. 11 figs., 15 tabs.

    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.

    For the research and development of erosion-resistant abradable materials for the methane-fueled aircraft engine front section, a laser-aided surface reform technology was developed for Ti alloys and the like. In relation with the article 'Intermetallic Compound Coating Formation Technology,' an NiTi sprayed coating containing excess Ni solid solution was found to be quite high in resistance to erosion, and similar to Ti-6Al-4V in resistance to oxidation at 300 degrees C. Furthermore, an MCrAlY erosion-resistant coating was formed capable of resisting oxidation at temperatures higher than 1000 degrees C. In relation with the article 'Spraying Phenomenon Evaluation Technology,' studies were made of combustion synthesis reaction during plasma spraying and of the prediction of flight trajectories of different powders, for which optical fiber dichroic temperature measuring, 2-dimensional imaging, and LDV (laser Doppler velocimetry) were applied in combination. Concerning the spraying of intermetallic compound coatings, a temperature rise occurred when heating by laser was performed simultaneously with the laser-induced combustion synthesis reaction. In relation with the article 'Technology of Multiple Spraying on Curved Substrate,' it was found that the gas cooled method works effectively when spraying an erosion-resistant coating onto a thin Ti alloy made turbine blade.

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

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

    Evaporation/diffusion tests are conducted in which 10 liters of liquid hydrogen is discharged instantaneously from a certain altitude toward the middle of spill surfaces. Four types of spill surfaces are used, which are soil, concrete, crushed stone, and water. Tests of continuous discharge of 50 liters of liquid hydrogen and of ignition/combustion are also carried out. The evaporation/diffusion phenomenon of liquid hydrogen is found to be greatly varied dependent on the spill surface type. The rising speed of the visible vapor mass is fairly great, and is approximately 1m/sec or more on any of the spill surfaces. Vapor diffusion is the fastest on the crushed stone spill surface where lateral expansion is the least, which is excellent from the viewpoint of safety. It is found that the rise of the vapor mass formed just after liquid hydrogen discharge is attributable to its own buoyancy. The flame of burning hydrogen is colorless and transparent, barely visible just like shimmering heat haze. When sodium bicarbonate power is lightly scattered all over the flame, it becomes obviously visible because of its turning orange due to the color flame reaction of sodium. Documentary records are also investigated. (NEDO)

    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%. In fiscal 1998, studies center about the establishment of a film fabrication process for a medium-are substrate and about the enhancement of its conversion efficiency, and facilities capable of dealing with large-area substrates are introduced and operated. In a typical achievement, a CdTe solar cell is experimentally fabricated in a process which is wholly under normal pressure, and the product with an aperture area of 1376cm{sup 2} exhibits a conversion efficiency of 10.5% according to JQA (Japan Quality Assurance Organization).

    Recently, automotive parts uses move resin products or pipe-like products in order to achieve high quality or light weight. Additionally, the shape of automotive parts becomes more complicated. The rotary stretch bending method, although it is most popular method of bending a pipe, has some problems, such as a bending radius is limited due to use of bending mold, a thickness of an outer side of a bending portion is thinner, and a product is scratched easily during manufacturing. We have developed a three dimensional pipe bending process using a floating expanding plug and confirmed that this method can solve the above problems. 2 refs., 9 figs., 3 tabs.

    The research and development project is implemented for production of low-cost, large-area modules of CdTe solar cells by the high-quality film-making process and high-function patterning, and the FY 1999 results are reported. The research program for the large-area TCO film-making technologies involves investigations on improvement of SnO{sub 2} film quality by the mist method and continuous film-making, which lead to continuous, stable production of 34 substrates of low resistance of 9.7{omega} on the average. The program for production of the large-area, thin-film CdS/CdTe solar cells involves production of TCO and CdS by the mist method, and patterning of the laminated TCO/CdS film by laser scribing. The CdTe film is formed by the atmospheric pressure CSS method, and treated with CdCl{sub 2} to improve its crystallinity. The CdTe film is patterned by sand blasting, and provided with the carbon and silver electrodes by screen printing, to complete the cell. The process is totally effected at the atmospheric pressure, needing no vacuum device. The CdTe solar cell assembly (130 cells connected in series, opening area: 5,413cm{sup 2}), fabricated on a trial basis, achieves a conversion efficiency of 10%. (NEDO)

    Research and development was conducted for reliable CdTe solar cell modules, large in area and high in efficiency. In the study of large-area CdS thin film fabrication, a conversion efficiency of 12.5-14.2% was achieved in a cell in a large-area substrate using a mist method-aided process of continuous CdS film fabrication. In the study of large-area CdTe thin film fabrication, the optimization was studied of the base-forming CdS film fabrication conditions and of the CdTe film fabrication conditions in a method using a CdTe powder processed by dry kneading, and a conversion efficiency peak was found to exist when the CdS film thickness was in the range of 700-900 angstrom. In the fabrication of large-area submodules, a large-area substrate was taken up, and TCO (transparent conducting oxide) film was fabricated by the mist method, CdTe film by the normal pressure CSS method, electrodes by the screen printing method, and CdTe film patterns by the blast method.

    Described herein are emission control technology and exhaust gas cleaning measures for internal combustion engines. Gas turbines burn relatively high-quality fuels, such as natural gas, kerosene, diesel oil and gas oil, where the major concerns are to reduce NOx and dust emissions. The NOx abatement techniques fall into two general categories; wet processes which inject water or steam, and dry processes which depend on improved combustion. Power generation and cogeneration which burn natural gas adopt lean, premixed combustion and two-stage combustion as the major approaches. Low-speed, large-size diesel engines, which realize very high thermal efficiency, discharge high concentrations of NOx. Delayed fuel injection timing is the most easy NOx abatement technique to meet the related regulations, but is accompanied by decreased fuel economy. Use of water-emulsified fuel, water layer injection and multi-port injection can reduce NOx emissions without decreasing fuel economy, depending on optimization methods adopted. Automobile gasoline engines are required to further clean exhaust gases by catalystic systems. 9 refs., 10 figs., 6 tabs.

    With an objective to improve efficiency and reduce cost of CIS-based thin film solar cells, research and development has been made on technologies to increase high-quality CIS film area and technologies to increase speed in the manufacturing process. This paper describes the achievements attained during fiscal 1997. The research covered development of technologies to form high-grade Cu (In, Ga) Se{sub 2} (CIGS) film by using the multi-dimensional deposition process, component technologies for forming a rear electrode, a buffer layer and a transparent electrode, and patterning technologies. As a result of the research, thickness of the CIGS film was reduced to half as much as that of the conventional films, having achieved conversion efficiency of 13.1%, which corresponds to about 90% of the conventional CIGS solar cells. In addition, elucidation was made on the effect of an MoSe{sub 2} layer existing on interface with CIGS/Mo in a CIGS solar cell imposed on solar cell characteristics. In developing an Mo film laser scribing technology, intensity dependence of laser energy was made clear, the energy being required for scribing according to surface condition of the Mo film. (NEDO)

    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.

    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)

In relation with system safety design, investigations continued into Japanese and foreign manuals and regulations about the handling of hydrogen and its peripherals, and safe design guidelines (draft) were compiled. Anomalies and accidents supposed to be typical of each of the systems concerned were investigated. As for accident-and-safety analyses, incorporation of a turbulence model was studied in relation to models representing the leak, evaporation, and diffusion of liquid hydrogen, and improvement was achieved when the scope of evaluation was enlarged concerning the hydrogen detonation model. The integration of the two models was discussed for the due evaluation of a series of processes of liquid hydrogen leak, evaporation, diffusion, and detonation. Calculation was performed for two assumed accidents, and the results were found to justify the integration of the two models. (NEDO)

So the project cannot remain effective unless constant efforts are made to foresee future trends of technology and optimize it as the making of entire system for the project. In this project, new technologies which are not up for development are also investigated. Their feasibility should be studied, if necessary. From the foregoing point of view, new technologies are studied, collected and evaluated. Thus, useful suggestions and proposals may be made as to the course for the project to follow, as well as its research and development. Proposals highly evaluated up to FY 1995 are the hydrogen-oxygen internal-combustion Stirling`s engine, hydrogen production by solid oxide electrolysis, magnetic refrigeration technology for liquefaction of hydrogen, solar thermal hydrogen production with iron sponge technology, and hydrogen producing technology with photocatalyst. Conceptual investigation themes in FY 1996 are the hydrogen internal-combustion Stirling engine, solar thermal hydrogen production, phototransformation process, and high-temperature steam electrolysis. 9 figs., 54 tabs.

    Described herein are the FY 2000 results of the survey on the technological trends of utilizing the reactions with metals in a living body, noting the bio-processes effectively coping with the environmental problems. The effects of heavy metals on microorganisms have been investigated on the molecular biology level, but are not fully elucidated. Recently, the microorganisms capable of converting inorganic metal ions in water into the insoluble compounds have been known, leading to possibility of bioremediation to solve pollution by heavy metals, which have detrimental effects on human health. Heavy metals must be recovered, because they are not extinct by decomposition. The plant aided purification has been attracting attention to cope with heavy metals accumulated in soil. Application of bacteria-aided leaching, which is adopted as one ore smelting process, to the technologies for utilizing metals in a living body has been expected, because diversified activities of inanimate matters in extreme environments have been known. Recently, bio-machining of metals aided by Thiobacillus ferrooxidans, one species of independent nutrient bacteria capable of eating metals, has been developed to a potentially viable stage. (NEDO)

    For the purpose of preventing closed waters from eutrophicating, COD regulations and nitrogen and phosphorus waste water regulations are executed in Japan, but practically applicable techniques for this purpose are a few. Concerning technology for removing nitrogen and phosphorus in waste water, this paper describes the actual situation of two industries, electroplating and alumite processing, and applicable techniques. Among various nitrogen removal methods, the biological treatment method has been used practically in many cases and is applicable to practical use. While there are many kinds of physical and chemical treatment methods, applicable methods are limited. In removing nitrogen, the coagulating sedimentation method with Ca salt, Al salt and Fe salt is effective generally for orthophosphate. At electroplating factories, various forms of phosphorus and nitrogen compounds are used as plating chemicals. In treating waste water containing phosphorus, the coagulating sedimentation method is used most frequently. The oxidation + coagulating sedimentation method, the autolysis + oxidation coagulation method, and the evaporation method are effected, though the examples of their implementation are small in number. 15 tabs.

    This paper introduced the sensor technology for food manufacturing industry. If sugar concentration in main raw material is too high in the amino acid fermentation, control of the concentration is required because fungi growth is inhibited. A controlling method for sugar concentration was developed by using the correlation between consumption of NH {sub 3} for pH adjustment and sugar consumption in place of conventional analyzing method and was introduced in the gulutamic acid fermantation. BOD sensor was developed to enable the selective measurement of organic substances which can be processed by organisms, and measuring time was shortened from previous five days to 30 minutes. Since many organics absorb infrared ray, near infrared analysis is suitable for food analysis and on-line analysis has high possibility. When this method is applied to measure moisture in fishes and meats, continuous measurement can be made nondestructively and without contacting, and further the precision is {plus minus} 0.1%. Simultaneous multi-composition analyses are carried out by continuous spectrum and near infrared method using higher rate scanning. Sensor development for taste and smell has started. 10 refs., 4 figs., 4 refs.

    Research and development was conducted for the development of amorphous solar cell modules for power generation, high in performance and low in production cost. In the effort to develop high-performance solar cells, optimum device designs including an advanced light confinement structure or the like were studied, and a 25% reduction in the total power generation layer thickness and a 7% increase in efficiency in power generation were consistently achieved in an a-Si/a-SiGe solar cell. In the effort to develop low-cost process technologies, as the result of studies involving the optimization of high-speed film fabrication requirements such as hydrogen dilution and a high-speed/high-precision patterning method and the like, an initial conversion efficiency of 11.2% was attained, which was the world high for a 90 cm times 90 cm-large a-Si/a-SiGe solar cell. This being equivalent to a post-stabilization efficiency of 10%, the fiscal 2000 target was achieved. A solar cell module production cost assessment was performed based on the result, and a module cost of 133 yen/W (in case of 100 MW/year production) was realized, which again meant the achievement of the fiscal 2000 target.

    Waste disposal by incineration is in wide use, inevitably discharging the unburnt portion or ash as the residue, and the residue contains heavy metals and dioxins. New slagging technologies capable of dealing with the situation, respecting in addition the effective use of resources, are now attracting attention, and are coming into popular use. IHI has already developed three types of melting technologies, which are the residual carbon combustion type, the joule-heating furnace type, and the coke-bed furnace type, and has already delivered to clients some facilities using these technologies. In this report, the three types are outlined, and the joule-heating furnace is taken up to explain the process of development up to commercialization. In the joule-heating furnace, molten slag (resistivity several ohms/cm at 1300degC) is electrified for the melting of ash by joule heat, and the result is a high-quality slag containing less chlorine thanks to the electrochemical decomposition. Studies were conducted about exhaust gas cleaning, silent operation, and cost performance (using only one electrode), etc., by operating 2.4t/d and 10t/d demonstration plants, and the efforts have culminated in the commercialization of the technology. 6 refs., 9 figs., 7 tabs.

    A microcrystalline Si thin film is used to form the i-layer of a narrow gap a-Si based thin film solar cell. 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)

    In this research, the data of advanced technology of micromachines in the USA have been searched, collected, and arranged from the US patent information, technical journal information, and newspaper and general journal information. According to demand, the main undertaking information was interviewed from well-informed persons. The data were compiled as advanced technology trend of micromachines in the USA. Sensors are remarkably predominant in the elemental technology. There are also important topics in the fields of actuators, motors, lenses, devices, and structures. On the other hand, materials, etchings, packages, motive powers, and softwares are also important elemental technology in spite of their less information. From the viewpoint of usage, detection systems are remarkably predominant. Then, robots, processing systems, optics, analysis systems, motive power systems, medical systems, and acoustic systems are also important. From the viewpoint of industrial sector, the environmental items are predominant. Automobiles, medical treatments, and information communications follow the above. When new relationships to the secondary usage and tertiary usage are not found, it would be rather hard to express such a technology development trend more clearly.

    This paper discusses simple measuring methods for water quality. There are various purposes for measuring water quality. It is not necessary to measure the water quality in an official way by taking a lot of labor and cost. Simple measuring methods are often adopted. By applying simple methods, measuring points and frequency of main discharge processes can be increased, resulting in the detailed evaluation and monitoring. Easy safety check for earth filling waste and soil pollutants is realized. Daily inspection and atmospheric measurements at accidents and disasters are easily promoted. The simple methods require easy and rapid operation, sensibility, accuracy and reproducibility suitable for the purpose, small size apparatus, low cost for measurements, and safety against used harmful matters. Coloring reaction is utilized for most of the measuring principles of simple methods, which include tests using test papers, pack tests, colorimetric tests, and tests using photoelectric colorimeter. The bacteria detection includes titration methods using dropping bottles, tablets and syringes, and tests using test papers. A measuring kit for the enzyme immunity method is commercialized. Cooperation of experts, measuring operators at the site and citizens is also indispensable. 7 refs., 3 figs., 2 tabs.

    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.

For production of high-function ceramic materials at low temperature, the soft solution process is proposed for the in-situ production of these ceramic materials from the aqueous solution without using high temperature or high energy. For example, the high-functional ceramic material can be produced in-situ on a substrate by reacting the highly active aqueous solution with the substrate by a combination of, e.g., the hydrothermal and electrochemical reactions, without needing post-treatment under heating. For the marine biological technologies, deposition of living organisms is described. A geodome is developed for utilizing very deep (50m or deeper) underground spaces. It is a dome-shaped space supported by no strut, having dimensions of 50m in diameter and 30m high not to affect the surrounding environments, e.g., underground water. The techniques for creating advanced functional materials are developed by combining, e.g., laser, plasma, ion and magnetic field in diversified manners. (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%.

    Group activities in fiscal 1993 are reported. In the study of hydrogenation refining of the naphtha fraction under the project for 'the upgrading of coal oil and the development of oil blending technology,' a hydrogenation experiment is conducted for deheterocyclicity for in the naphtha fraction (90-180 degrees C). The neutralization process is found to greatly accelerate denitrification, multiplying the rate constant 2-5 times at 300 degrees C. In the research and development of application technologies, the ASTM-D4625-86 method is applied to the storage test of crude oils such as naphtha from liquefied Yallourn coal, kerosene, and light oil, and the results are compared with those from natural storage. It is then found that this acceleration test is applicable even to oils from coal liquefaction. In the research and development of novel catalysts, it is found, relative to the 1st-stage hydrogenation catalyst, that an increase in the amount of supported tungsten enhances the activity and life of the catalyst and, relative to the 2nd-stage hydrocracking catalyst, that YD zeolite is effective in prolonging the life of the catalyst.

    The latest measurement equipment and repair method were introduced into the work area of all refractories in the process of torpedo cars, hot metal preliminary treatment, hot metal pans, secondary refining, and cast pans so as to improve the cost of the newest advanced steelmaking refractories. As a result, the refractory cost could be reduced by 10%. This paper introduces the improvement in RH refractories and refractories for hot metal preliminary treatment. As for basic items, in addition to the visual observation, the thickness of refractories was quantified using equipment (laser profile meter, thermotracer, and NS sensor) for the furnace stop in the minimum remaining length. An ITV was also installed in the facilities where the visual check is difficult to carry out. Repair is mainly done by spraying. A thermal spraying repair method with high durability was used for the repair. A method that relieves a thermal shock was used for preheating. Moreover, measures that make the temperature gradient in the thickness direction uniform by using newly developed microwave drying equipment were taken for drying of unburned refractories. 4 refs., 13 figs., 2 tabs.

    Described herein are the results of the FY1994 research program for energy conversion technology using chemical reactions by the aid of solar energy. The demonstration runs were conducted by a bench-scale unit, which was operated stably for 100h, to produce promising results. The catalyst exhibits stable performance, without showing a sign of deactivation. It is found that the heat pump system works well, without being interfered with accumulated by-products. A heat of approximately 2,100kcal/h is recovered. It is confirmed that steam of 150{degree}C and 200{degree}C is generated from hot water of 80{degree}C and 95{degree}C, respectively. The bench-scale runs show a thermal efficiency of around 10%, which is lower than the target level. However, the runs with hydrogen-occluding alloy attain a process thermal efficiency of 30%. The system in which solar collector and chemical heat pump units are combined is evaluated with respect to its economic efficiency and operability for its eventual commercialization. 6 figs., 2 tabs.

(1) On development of epitaxial growth technology of lattice mismatching systems, the optimum structure of InGaAs strain intermediate layers was studied for reducing a dislocation density by lattice mismatching of GaAs layer grown on Si substrate and difference in thermal expansion coefficient. The effect of strain layer on dislocation reduction was found only at 250dyne/cm in strain energy. Growth of GaAs layers on the Si substrate treated by hydrofluoric acid at low temperature was attempted by MBE method. As a dislocation distribution was controlled by laying different atoms at hetero-interface, the dislocation density of growing layer surfaces decreased by concentration of dislocation at hetero-interface. (2) On development of high-efficiency tandem cell structure, tunnel junction characteristics, cell formation process and optimum design method of lattice matching tandem cells were studied, while thin film cell formation was basically studied for lattice mismatching tandem cells. 45 figs., 8 tabs.

    In 1994, a memorandum on the research cooperation was agreed between NEDO and BPPT (The Agency for the Assessment and Application Technology) in Indonesia, based on the request for the coal liquefaction technology cooperation from BPPT. It includes the following items: conference for professionals to be held, invitation and training of Indonesian engineers, activity for joint field survey and potential survey of location of coal liquefaction commercial plant. Further in 1997, the secondary memorandum was concluded for the potential survey for securing the hydrogen required for coal liquefaction by coal gasification. The survey was summarized as the potential survey for location of coal liquefaction. In the testing study for improving economical efficiency of liquefaction process, it was made clear that the higher the Fe content of Banko coal is, the higher the reaction of liquefaction is, and that Fe compounds in coal show catalysis. In the Soroako area in Sulawesi island, there are the nickel mine run by PT. Inco. Soroako limonite is promising as catalyst material for commercial-scale coal liquefaction. In the gasification method, the plant construction cost increases, but the production amount of coal-derived liquid can be increased. That is more profitable than the production of hydrogen from natural gas. (NEDO)

    The research objective is the development of environmentally benign coal liquefaction technology and the studies on internationalization of coal liquefaction technology. Implemented for the former are (1) research on improvement and rationalization of liquefaction process and (2) research on advancement of liquefaction base technology. In (1), studies were made on in-oil preprocessing technology and scale suppressing measures for the purpose of obtaining reform/high grade of coal, and on improvement of liquefied oil collecting ratio, sophistication of coal slurry and attainment of light oil/high grade from liquefied crude oil for the purpose of optimizing liquefaction reactive conditions and improving a solvent. In (2), in developing high activity/high dispersion type new catalysts, catalytic sufurization behavior and activity manifestation mechanism were explored, as were iron hydroxide based iron ore properties and liquefaction reactive characteristics. The initial reactive characteristics of liquefaction for example were investigated for the purpose of collecting basic data for expanding kinds of coal. In order to attain the latter objective of the research, a feasibility study of liquefaction location was conducted, as were the investigation including sampling of iron ore for catalytic material and the investigation of coal gasification technology. After the completion of the Australian brown coal liquefaction project, the development of the coal liquefaction technology commenced in fiscal 1994 produced a number of useful records and ended in 1997.

    For standardization under information security evaluation criteria, an evaluating technique CEM (Common Methodology for Information Technology Security Evaluation) was constructed as ISI/IEC15408. The method, however, is abstract in content and the evaluation work thereunder requires much time and accompanies economic difficulties. In dealing with the situation, investigations were conducted into security evaluation related techniques and manufacturing/quality control techniques in use at information processing product developing sites, and a CEM technique is materialized. Using the proposed technique, developers themselves can evaluate security in the development process and workloads imposed on evaluating organizations may be reduced because evidential items necessary for 3rd party evaluation may be gathered. Since the developed technique is verified by an official evaluating organization, it is expected to be an effective techniques not contradicting existing operating techniques. It may be also said that this technique is a method whereby developers will collect evidential items necessary for their development efforts. The result will be presented in the form of a proposal for an evaluating techniques standard for ISO/IEC JTC1 SC27. (NEDO)

    Research and development has been performed on a high throughput forming technology and a modularization technology for thin film poly-crystalline solar cell modules. This paper summarizes the achievements in fiscal 1999. In developing the high throughput forming technology for a high-quality thin film, research has been made on a low-cost VEST process to re-utilize substrates by separating the thin film from the substrate. In the melting re-crystallization process, it was discovered that plasticity deformation of the substrate can be reduced greatly by raising the substrate heating temperatures. It was also found out that substrate warping amount can be reduced to about one-fifth of the conventional amount by making the thickness greater than 1.5 mm and raising the heating temperatures higher than 1300 degree C. In developing the thin film modularization technology, it was indicated that the property improving effect remains the same even if the hydrogen passivation method is changed from the hydrogen ion injection to the hydrogen plasma processing. In the trial fabrication of the thin film modules, a conversion efficiency of 13.1% was achieved in nine-cell structured modules. (NEDO)

    The aim is to realize the practical application of the above-named solar module expected to exhibit higher efficiency and reliability and achieve cost reduction through consumption of less materials. In fiscal 1998, 1) technologies were developed to reduce substrate warpage during recrystallization for the higher-throughput fabrication of high-quality thin films and 2) technologies were also developed for the realization of higher-throughput fabrication of thin films and for efficiency improvement for thin-film modules. Under item 1), experiments were conducted by simulation for reducing warpage to occur in thin-film polycrystalline Si substrates during fabrication by melting and recrystallization. Under item 2), for the development of thin-film cell high-throughput technologies, studies were started on a more practical hydrogen plasma process to challenge the conventional process of crystal defect inactivation by hydrogen ion injection with which achievement of high throughputs is difficult. For the development of technologies for the enhancement of thin-film module efficiency, efforts were exerted to realize a 10cm times 10cm square shape for the enhancement of efficiency in the process of filling modules with cells. These efforts achieved a great step toward future practical application. (NEDO)

    Research and development was carried out for the production of a Cu(InGa)Se{sub 2}-based thin-film solar cell submodules, having a conversion efficiency of 13% and an area of 30 cm times 30 cm, at a cost of 140 yen/Wp (at a production rate of 100 MW/year). In the effort to fabricate a large-area photoabsorption layer, reproducibility was improved by the introduction of a technique for controlling the Cu/III group ratio in and the thickness of the metal precursor film by the use of ICP (inductively coupled plasma) analysis. A maximum conversion efficiency of 12.93% and a reproducibility of 85% were achieved, which meant that the production cost goal was achieved. In the effort to develop a high-resistance buffer layer fabrication technology, a fabrication method was developed in which a lower limit was specified for solution transparency enabling the completion of the film fabrication process with no colloid formation occurring in the solution. For preventing the high-resistance buffer layer fabrication process from growing too complicated, the steps were integrated into one for the MOCVD-ZnO:B window layer. As the result, the film fabrication process subject to the film fabrication control based on solution transparency was simplified for a great increase in reproducibility. (NEDO)

    Fiscal 1997 is the first year of another 4-year-long research and development phase. In addition to researches for improving on thin-film polycrystalline Si cell efficiency that have been under way, new efforts are started, which include the development of practicality-conscious thin film producing technologies aiming at higher throughput and yield and the development of modularization process technologies which are necessary for putting thin-film cells to practical use. Concerning the formation of a power generation layer on a polycrystalline Si thin film formed by the ZMR (zone-melting recrystallization) process, studies are conducted for improvement on its throughput and yield using a new CVD (chemical vapor deposition) unit. A method of modularization is evaluated, which involves a laminate of a thin-film cell attached to a resin-coated, reinforced glass substrate and an EVA (ethylene vinyl acetate) back film. A remarkable achievement is earned toward the practicalization of technologies of thin film formation enhanced in quality and throughput and technologies of thin film modularization. (NEDO)

    The project aims to establish a manufacturing process that enables both high-quality CuInSe{sub 2} (CIS) film solar cell enlargement and cost reduction and to develop a device structure which uses less heavy metal for the purposes of increasing the CIS thin-film solar cell size and efficiency and decreasing environmental impact. Several element technologies have been established for increasing the area of high-efficiency Cu(In, Ga)Se{sub 2} (CIGS) solar cells. Concerning the enlargement of the photoabsorption layer which is to assume the most important role, it is found that a high-quality CIGS film, which is near homogeneous though within a 10cm times 10cm area, is fabricated by an in-line vapor deposition method. As for dead area reduction and high-speed patterning, it is found that laser scribing works effectively in the patterning of the window layer and photoabsorption layer. As for reduction in the use of heavy metal, a high efficiency of 16.2% is attained in a cell not using a CdS film as expected in the case of a cell using a CdS film, this thanks to a CIGS film surface reforming technique. The technique of junction formation for CIGS solar cells is improved, and then a true efficiency of 18.5% is achieved. (NEDO)

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

    Research and development was made with an objective to achieve conversion efficiency of 13% in a 30 cm times 30 cm size submodule of a CIS-based thin film solar cell, and to develop a manufacturing technology that can achieve 140 yen/Wp. This paper describes the achievements attained during fiscal 1997. In fiscal 1997, based on the achievements reached during the previous year, a submodule with a size of 10 cm times 30 cm was fabricated for an attempt of improving the open voltage and short circuit current density. Simultaneously, the applicability thereof to a module with an area as large as 30 cm times 30 cm was evaluated. As a result of experimental discussions, enhancement in the open voltage was verified by increasing amount of Ga or sulfur, but it was not possible to achieve 600 mV or higher. In the research of component technologies to establish a mass production process, research and development was made on a high-resistance buffer layer film forming technology, a high-quality window layer film forming technology, a high-quality metallic rear electrode film forming technology, and patterning technologies.

    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.

    The operation continues of the experimental device capable of producing 10 tons/year of SOG (spun on glass)-Si, and efforts are under way to carry out improvements, to verify such improvements for the results, and to develop operation control technologies. During the operation, improvements are made with respect to the length of stable operation period, granule quality, and device operation, and the results are verified. An automated control test system is verified, and a reactor tube newly developed by Shin-Etsu Chemical Company is subjected to a durability verification test. On the other hand, development is started of SiC-CVD (chemical vapor deposition) technology for materials for large reactor tubes, studies are started on a basic experimental device, basic studies are conducted for designing a large reactor, and investigations are conducted of a large plant conceptual design, an automated control system for reactors, and so forth. The results achieved are all found to be satisfactory. Above all, the granule quality is improved to be quite high in purity, and a cast cell made from improved granules exhibits a photoelectric conversion efficiency to exceed 13%. It is also found that the newly developed reactor tube is stronger than conventional reactor tubes and will be advantageous over others in the future enlargement of devices. (NEDO)

    The aim is to develop a fluidized bed reactor high in productivity and low in power consumption for the realization of mass production of low cost polycrystalline silicon usable for solar cell construction. An experimental device capable of producing 10 tons/year of SOG (spun on glass)-Si is built and operated. The fluidized bed reactor treating trichlorosilane as the material and the product quality achieve the initially set goals, and the essence is seized of operation management technology. In fiscal 1986, for development of the technology into a practical application technology, designs are prepared for a larger reactor unit and a large plant of the commercial scale. From the viewpoints of production efficiency and cost, the enlargement of a reactor unit is an inevitable task to discharge before practical application. There are two challenges to meet. One is the development of technologies for manufacturing large reactor tubes strong enough to withstand practical service and the other the development of a reactor structure fit for dimensional enlargement. It is then found that the concept of an economically optimum design relative to device series or device block formation is variable in the case of large plants, dependent on the scale of production, and that therefore it is necessary to arrange problems in a proper order to facilitate further deliberation.

    The chlorosilane hydrogen-reduction technology development period may be divided into the first phase (fiscal 1980-1985) and the second phase (fiscal 1986-1988). During the former phase, efforts were exerted to develop a small experimental device (10 tons/year class) and technologies to operate the same. Important challenges were to cause reaction to occur only on the seed grains in the reactor and to create a proper material for the reactor tube. In the latter phase, element technologies were developed, indispensable for the development of a practical reactor. Endeavors exerted to solve these challenges were the development of a high-strength large-diameter reactor tube, the development of an SiC-CVD (chemical vapor deposition) coating technology, and the development of a technology to join parts to the ceramic-made reactor tube. After eight years' striving, a fluidized bed reactor has been successfully constructed, capable of continuously reducing trichlorosilane by hydrogen. The success promises stable production and supply of polycrystalline silicon. The SOG (spun on glass)-Si produced by the reactor is pure enough to serve the purpose of photovoltaics, and its unit cost has been lowered as initially intended. (NEDO)

    This review article focuses on the utilization of several catalysts during coal pyrolysis and gasification. In situ or off line catalytic upgrading of volatile matters during pyrolysis of low rank coals is carried out in pressurized H2 with different reactors to produce BTX (benzene, toluene and xylene). When NiSO4 and Ni(OH)2 are used in the hydropyrolysis of Australian brown coal using an entrained bed reactor with two separated reaction zones, BTX yield reaches 18-23%. MS-13X zeolite and USY zeolite mixed with Al2O3 are effective for producing BTX with powder-particle fluidized bed and two-stage reactors, respectively. Catalytic gasification is described from a standpoint of direct production of SNG(CH4) from coal and steam. When K2CO3 and Ni are compared for this purpose, Ni catalyst is more suitable at low temperatures of 500-600degC, where CH4 formation is thermodynamically favorable. Fe and Ca catalysts can successfully be prepared from inexpensive raw materials and are rather active for steam gasification at {>=}700degC. The use of upgrading and gasification catalysts is discussed in terms of preparation, performance, life and recovery. 27 refs., 6 figs., 2 tabs.

    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.

    The membrane processes have played important role in the industrial separation process. These technologies can be found in all industrial areas such as food, beverages, metallurgy, pulp and paper, textile, pharmaceutical, automotive, biotechnology and chemical industry, as well as in water treatment for domestic and industrial application. Although these processes are known since twentieth century, there are still many studies that focus on the testing of new membranes' materials and determining of conditions for optimal selectivity, i. e. the optimum transmembrane pressure (TMP) or permeate flux to minimize fouling. Moreover the researchers proposed some calculation methods to predict the membrane processes properties. In this article, the laboratory scale experiments of membrane separation techniques, as well their validation by calculation methods are presented. Because membrane is the "heart" of the process, experimental and computational methods for its characterization are also described.

    Process mining includes the automated discovery of processes from event logs. Based on observed events (e.g., activities being executed or messages being exchanged) a process model is constructed. One of the essential problems in process mining is that one cannot assume to have seen all possible...... behavior. At best, one has seen a representative subset. Therefore, classical synthesis techniques are not suitable as they aim at finding a model that is able to exactly reproduce the log. Existing process mining techniques try to avoid such “overfitting” by generalizing the model to allow for more...... support for it). None of the existing techniques enables the user to control the balance between “overfitting” and “underfitting”. To address this, we propose a two-step approach. First, using a configurable approach, a transition system is constructed. Then, using the “theory of regions”, the model...

  20. Partial processing

    International Nuclear Information System (INIS)

    1978-11-01

    This discussion paper considers the possibility of applying to the recycle of plutonium in thermal reactors a particular method of partial processing based on the PUREX process but named CIVEX to emphasise the differences. The CIVEX process is based primarily on the retention of short-lived fission products. The paper suggests: (1) the recycle of fission products with uranium and plutonium in thermal reactor fuel would be technically feasible; (2) it would, however, take ten years or more to develop the CIVEX process to the point where it could be launched on a commercial scale; (3) since the majority of spent fuel to be reprocessed this century will have been in storage for ten years or more, the recycling of short-lived fission products with the U-Pu would not provide an effective means of making refabrication fuel ''inaccessible'' because the radioactivity associated with the fission products would have decayed. There would therefore be no advantage in partial processing

    Many of the measurements and observations made in a nuclear processing facility to monitor processes and product quality can also be used to monitor the location and movements of nuclear materials. In this session information is presented on how to use process monitoring data to enhance nuclear material control and accounting (MC and A). It will be seen that SNM losses can generally be detected with greater sensitivity and timeliness and point of loss localized more closely than by conventional MC and A systems if process monitoring data are applied. The purpose of this session is to enable the participants to: (1) identify process unit operations that could improve control units for monitoring SNM losses; (2) choose key measurement points and formulate a loss indicator for each control unit; and (3) describe how the sensitivities and timeliness of loss detection could be determined for each loss indicator

    1986-01-01

    Process automation technology has been pursued in the chemical processing industries and to a very limited extent in nuclear fuel reprocessing. Its effective use has been restricted in the past by the lack of diverse and reliable process instrumentation and the unavailability of sophisticated software designed for process control. The Integrated Equipment Test (IET) facility was developed by the Consolidated Fuel Reprocessing Program (CFRP) in part to demonstrate new concepts for control of advanced nuclear fuel reprocessing plants. A demonstration of fuel reprocessing equipment automation using advanced instrumentation and a modern, microprocessor-based control system is nearing completion in the facility. This facility provides for the synergistic testing of all chemical process features of a prototypical fuel reprocessing plant that can be attained with unirradiated uranium-bearing feed materials. The unique equipment and mission of the IET facility make it an ideal test bed for automation studies. This effort will provide for the demonstration of the plant automation concept and for the development of techniques for similar applications in a full-scale plant. A set of preliminary recommendations for implementing process automation has been compiled. Some of these concepts are not generally recognized or accepted. The automation work now under way in the IET facility should be useful to others in helping avoid costly mistakes because of the underutilization or misapplication of process automation. 6 figs

    For the physical modeling system of Technology Research Center, Japan National Oil Corporation, data acquisition on the ocean and ground can be simulated using models. This system can provide data for verification of the data processing and elastic wave simulation algorithm. This can also provide data for decision of experiment specifications by making a model simulating the underground structure of the given test field. The model used for the physical modeling system is a gradient multilayer model with six-layer structure. Depth migration before stacking was conducted using data obtained through two acquisition methods, i.e., up-dip acquisition and down-dip acquisition. The depth migration before stacking was performed for data obtained by up-dip acquisition in addition to the records obtained by down-dip acquisition. Consequently, a definite reflection surface was observed, which has not been observed from the processing results of down-dip acquisition data. 9 figs.

    This paper summarizes the current status and the international activities in the technologies to decompose fleon (CFC) which can cause ozone depletion in the stratosphere and global warming. Discussions have been given in Japan on combustion decomposing method as a fleon decomposing technology, which can use generally available incinerators. A plasma decomposition process uses a high-frequency plasma device with an input of 182 kW which can process CFC-12 of 48 kg/h at a decomposition efficiency of 99.99% or higher. A reported catalyst decomposition method uses zeolites, alumina, TiO2-ZrO2-based oxide mixture, and iron oxide carrying activated carbon as catalysts. A super critical water decomposition process is reported capable of decomposing almost completely CFC-11 and CFC-113 at 400[degree]C and 320 or higher atmospheric pressure. The United Nations Environment Programme arranges international cooperations on the stratospheric ozone/fleon problem, and the committee has established an ozone depleting substance (ODS) decomposing technology authorization act. The currently available capacities of decomposing devices are by far lower than the banked ODS amount to be provided to decomposition. 3 refs., 3 figs., 7 tabs.

    The research and development project is implemented for the chemical processes which utilize supercritical fluids, in order to establish the basic technologies for the environment-friendly chemical processes. For the solvolysis, the conditions under which plastics are hydrolyzed in supercritical water are investigated, and the basic data are obtained for the optimum conditions under which thermoplastic resins are hydrolyzed. The mechanisms involved in hydrolysis of polymers in supercritical water are elucidated to some extent. The environment-friendly process for synthesizing polycarbonate in supercritical carbon dioxide gas is investigated, and the continuous flow sheets are established for securing almost 100% conversion in the presence of an inexpensive catalyst. For the oxidation, the tests are conducted to burn low-grade coal in supercritical water, and the conditions under which it is burnt without releasing acid and toxic gases are found. For the hydrogenation, heavy fuel oil is treated in supercritical water to produce the lighter products. The conditions under which light oils and gases are produced are clarified, and the basic data are obtained for producing light gases from the resultant coke as the by-product. (NEDO)

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

    Serious shortage is predicted on cokes for blast furnaces in the first half of the 21st century. In order to deal flexibly with the fluid world market in the future, it is necessary to have a technology developed, by which coals from coking coal to non-coking dust coal can be used. The Japan Iron and Steel Federation and the Center for Coal Utilization, Japan are working on research and development of a new process with enhanced environmentality and economy (SCOPE 21) as a coke manufacturing process to respond to the requirements arisen from the above situation. The process is assessed basing on basic technological seeds such as rapid coal heating and high-speed carbonization and reformation of middle to low temperature cokes. The organizations are moving forward an eight-year development program which has started in fiscal 1994. This paper reports the summary of the development, and results of investigations and researches performed during fiscals 1994 and 1995. Rapid heating tests, middle to low temperature coke reformation tests, and tests for plug transportation of high-temperature coal have been performed. It has been verified, for example, that rapid coal heating can improve coke strength. The development work is being promoted toward grain size distribution and upscaling problems. 5 refs., 16 figs., 2 tabs.

    The aim is to establish basic technologies for upgrading wide-gap semiconductor devices, fabricated mainly of SiC, in terms of their low-loss, high-speed, and high-power features. In the research and development of ultralow-loss power device technology, progress of the effort is reviewed, problems in the process of research and development are extracted, and technological trends are surveyed. In the development of basic technologies, an SiC crystal growing device is experimentally built and the process of crystal growth is assessed and analyzed, and tasks to discharge for higher quality and larger diameter are extracted. Basic technologies are developed relative to the epitaxial growth, interface control, and conductivity control of SiC etc. In the development of technologies for developing SiC into devices, technological development is carried out for the junction-type FET (field effect transistor), which involves termination structure optimization, high-voltage capability enhancement, and gate-off gain improvement. As for MOSFET (metal oxide semiconductor FET), MOS channel formation technology is developed and device-constructing technology is also developed.

Fiscal 1997 as the final year of the project advanced improvement in such transistor-using processes as formation and micro-processing of superconducting thin films to show enhancement in characteristics of high-temperature superconducting transistors and possibility of their application utilizing their high speed motions. Furthermore, fundamental technologies were studied with an aim on junction transistors to be applied as circuits. For field effect transistors, evaluation was performed on critical current distribution of step-type particle boundary junction to make it possible to evaluate characteristics of hundreds of transistors. At the same time, a magnetic flux quantum parametron gate with three-layer structure was fabricated to identify its operation. In superconducting-base transistors, strong reflection was recognized on temperature dependence of permittivity of an Nb-doped strontium titanate substrate used for collectors, by which barrier height was reduced. In the junction transistor and circuit technology, isotropic ramp-edge junctions were fabricated, and so was a frequency divider circuit with single magnetic flux quantum mode operation for evaluating high-speed response characteristics. High time resolution current was observed successfully by using a high-temperature superconducting sampler system. 148 refs., 127 figs., 4 tabs.

    Described herein are the FY 2000 results of the survey on the technological trends of utilizing the reactions with metals in a living body, noting the bio-processes effectively coping with the environmental problems. The effects of heavy metals on microorganisms have been investigated on the molecular biology level, but are not fully elucidated. Recently, the microorganisms capable of converting inorganic metal ions in water into the insoluble compounds have been known, leading to possibility of bioremediation to solve pollution by heavy metals, which have detrimental effects on human health. Heavy metals must be recovered, because they are not extinct by decomposition. The plant aided purification has been attracting attention to cope with heavy metals accumulated in soil. Application of bacteria-aided leaching, which is adopted as one ore smelting process, to the technologies for utilizing metals in a living body has been expected, because diversified activities of inanimate matters in extreme environments have been known. Recently, bio-machining of metals aided by Thiobacillus ferrooxidans, one species of independent nutrient bacteria capable of eating metals, has been developed to a potentially viable stage. (NEDO)

In the study of optimal conditions of the process, the progress of each unit reaction was experimentally confirmed. By measuring the reaction yield, optimal reaction conditions for expediting the reaction were found out. As a result, it was found that the proposed processes proposed both advance rather easily, and was thought that those are worthy of making further engineering study. In the study of improvement and optimization of the process, since some altered processes are considered for the processes presented, an investigational study was made on a method to calculate thermal efficiency which is one of the standards for the process evaluation, and thermal efficiencies in various processes were trially calculated, based on the calculating method. As a result, it was thought that this process is equal to other processes. (NEDO)

    The technical and economic viability of the fast breeder reactor as an electricity generating system depends not only upon the reactor performance but also on a capability to recycle plutonium efficiently, reliably and economically through the reactor and fuel cycle facilities. Thus the fuel cycle is an integral and essential part of the system. Fuel cycle research and development has focused on demonstrating that the challenging technical requirements of processing plutonium fuel could be met and that the sometimes conflicting requirements of the fuel developer, fuel fabricator and fuel reprocessor could be reconciled. Pilot plant operation and development and design studies have established both the technical and economic feasibility of the fuel cycle but scope for further improvement exists through process intensification and flowsheet optimization. These objectives and the increasing processing demands made by the continuing improvement to fuel design and irradiation performance provide an incentive for continuing fuel cycle development work.

    This paper invites to discuss the processes of individualization and organizing being carried out under what we might see as an emerging regime of change. The underlying argumentation is that in certain processes of change, competence becomes questionable at all times. The hazy characteristics...... of this regime of change are pursued through a discussion of competencies as opposed to qualifications illustrated by distinct cases from the Danish public sector in the search for repetitive mechanisms. The cases are put into a general perspective by drawing upon experiences from similar change processes...... in MNCs. The paper concludes by asking whether we can escape from a regime of competence in a world defined by a rhetoric of change and create a more promising world in which doubt and search serve as a strategy for gaining knowledge and professionalism that improve on our capability for mutualism....

    Digital images are used as an information carrier in different sciences and technologies. The aspiration to increase the number of bits in the image pixels for the purpose of obtaining more information is observed. In the paper, some methods of compression and contour detection on the basis of two-dimensional Markov chain are offered. Increasing the number of bits on the image pixels will allow one to allocate fine object details more precisely, but it significantly complicates image processing. The methods of image processing do not concede by the efficiency to well-known analogues, but surpass them in processing speed. An image is separated into binary images, and processing is carried out in parallel with each without an increase in speed, when increasing the number of bits on the image pixels. One more advantage of methods is the low consumption of energy resources. Only logical procedures are used and there are no computing operations. The methods can be useful in processing images of any class and assignment in processing systems with a limited time and energy resources.

    This report describes the results of effective fixing technique of CO2 by utilizing solar energy. First of all, the investigation was directed to the technique for synthesizing ethylene, hydrocarbons and alcohol by electrochemical reduction of CO2. The power required for this process is supplied by photovoltaic power generation. Development of excellent electrode catalyst is needed because the reduction of CO2 requires a high overvoltage. It is desirable to enhance the selectivity of the reaction for specific material and improve the transport process in the electrolytic cell. Next, designing of material and reaction of photocatalysts using semiconductor electrode and semiconductor particulate was examined. A semiconductor electrode made of FeS2 is inexpensive and has a high ability of collecting solar light. In the category of photocatalysis system, a photocatalytic system in which semiconductor particles are embedded in vesicle and a photpocatalyst based on potassium niobate are noteworthy. As biosystem, the method of reducing CO2 by calcareous algae which simultaneously advances fixing and calcification of CO2 by photosynthesis is noteworthy. 129 refs., 45 figs., 20 tabs.

    Hydrophilicity results when the surface of titanium dioxide is reduced for the specified oxygen to be replaced by hydroxyl groups. The ease with which such a structural change occurs is subject to variation between titanium dioxide crystal surfaces, and is dependent greatly on the atmosphere. No hydrophilic trend is observed in an atmosphere of oxygen only without moisture and, in darkness without light, hydrophobicity occurs early. Although the contacta angle titanium dioxide with water with stability is not known, yet it is presumed, on the analogy of the case of strontium titanate, that it is in the range of 20-40 degrees. A hydrophilic trend below the range is attrributed to structural changes. The control of surface wettability is one of the basic tasks to fulfill in various kinds of mechanisms and manufacturing processes. The technology of wettability control using a titanium dioxide coating which is quite durable will be applied not only to functions involving defogging, dripproof, and self-cleaning, but also to the control of heat transmission in the mechanism and to the bonding process.

    This metal melting system is a process to efficiently melt and regenerate scraps of aluminum, copper and iron by utilizing high-temperature energy obtained from pulverized coal-oxygen combustion. The process is intended to utilize coal in place of petroleum for reduced fuel cost. Joint studies have been carried out as a subsidy operation of the Agency of Natural Resources and Energy with a schedule of six years starting fiscal 1992. Development tests are being performed using a 5-ton/ch pilot plant facility since fiscal 1995 after having gone through experiments using a 1-ton/ch bench scale furnace. This paper reports the results obtained to date. Using the pilot plant facility, fiscal 1995 has achieved the initial target values, such as thermal efficiency of 55% or higher, and yield of 96% or higher for non-ferrous metals and 94% or higher for iron. The melting behavior in the furnace has improved the thermal efficiency as a whole by retaining the conditions in the preheating step for an extended period of time. The thermal efficiency has been improved better than with the bench furnace as a result of upscaling effect. 9 figs., 3 tabs.

    Investigations and researches have been made on disintegrated waste gypsum boards generated in building demolishing sites, with a target of recycling them as a raw material for boards. In the investigations, the actual status of discarding the disintegrated gypsum boards was identified, whereas the harmful substance contents such as of heavy metals were verified to be below the environmental criteria. As a method to remove impurities and foreign materials from the disintegrated waste gypsum boards, the hydration crushing method was established, in which volumetric change when hemihydrate gypsum returns to gypsum dehydrate is utilized, and bond of gypsum particles with each other and with impurities is destructed to separate them into simple substances. Furthermore, discussions were given on the reforming conditions to reform in an energy saving manner the disintegrated waste gypsum boards into high-quality large-size hemihydrate gypsum by using the wet-type process that utilizes the reversible reaction between hemihydrate gypsum and gypsum dehydrate in the disintegrated waste gypsum boards. A manufacturing process to put the recycled gypsum into practical use was also discussed. Prototype board fabrication and tests were performed by using the reformed gypsum board materials, wherein good results were obtained from all of the practical, chemical, and physical tests. (NEDO)

    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.

    As the result of a RUN-9 operation in the research on technologies for hydrogen production from coal and for pilot plants, it is found that the Muswellbrook, Datong, and Blair Athol coals are all suitable for gasification in pilot plants. Their handlability is considerably improved when the grain sizes after crushing are allowed to remain coarse (with the Blair Athol coal still retaining some disadvantage). A concept design is prepared for a HYCOL (hydrogen from coal) process demonstration plant. The reference coal is an imported coal similar to the Taiheiyo coal, and the hydrogen production target is set at 1-million m{sup 3}N/d (590t/d in terms of Taiheiyo coal) and hydrogen purity at 95% or higher. The whole process consists of coal gasification (with oxygen serving as gasification agent), dedusting, conversion to CO, desulfurization and decarboxylation (recovery of sulfur), and methanation. The gasification furnace is a 1-chamber entrained bed type with a 2-stage gyration flow. Dried and pulverized coal is conveyed aboard an air flow into the gasification furnace, where it is thrown into partial combustion reaction with the gasification agent for gasification in a high-temperature zone (1,500-1,600 degrees C), and the ash is taken out as slag. The generated gas is cooled in a heat recovery boiler, dedusted in a cyclone dust filter, and then forwarded to the washing unit. (NEDO)

    Through visits to US universities and research institutes, investigation was made on the trend of global environment-related research and possibility of their exchanging the result of research with the RITE (Research Institute of Innovative Technology for the Earth). To investigate the process technology to utilize microbes harmoniously with the environment, the visit was paid to Cornell University, Battelle Memorial Institute and Risk Reduction Engineering Laboratory, where the investigation was made on the environmental bioremediation with microbial functions and clean process production without by-producing substances to load the environment. To investigate the technical measures against the global warming, the visit was paid to Brookhaven National Laboratory, Massachusetts Institute of Technology, California University, Hawaii University and Pacific International Center for High Technology Research, where the investigation was made, through discussion and exchange of research information and opinion with researchers and engineers, on the possibility of their exchanging the result of research with the RITE. Judging from the investigation of this time, the research which is mutually complementary between Japan and USA is easy to promote, because their respective advanced fields do not overlap with each other. 88 refs., 11 figs., 6 tabs.

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

    This report summarizes the fiscal 1980 research result on removal process and equipment of H{sub 2}S from condensate and waste gas of turbine inlet steam and turbine outlet condensers of geothermal power plants. In the research on continuous measurement method of H{sub 2}S in geothermal steam, the continuous measurement equipment was completed by improving the heat conduction type steam qualitative dilution equipment developed in last year. The test result of this equipment in Onikobe geothermal power plant gave interesting data showing cyclic fluctuation of H{sub 2}S concentration. In the research on treatment of turbine inlet steam, both physical and chemical treatments were unpractical because of their very expensive costs. In the research on treatment of turbine outlet fluid by selecting RET method for waste gas and diffusion method for condensate, the field test result by using real fluid in geothermal power plants made it possible to select the optimum process according to conditions of turbine outlet fluid, and to estimate removal costs of H{sub 2}S precisely.

    By the use of superconductive technology, the following are aimed at: marked reduction in power loss of electrical equipment and power transmission path, and size/weight reduction in electrical devices by high current/magnetic flux density. The superconductive technology has advantages such as great energy saving effect, CO2 reduction and global environmental preservation. As an example, concerning the superconductive generator now being developed under the New Sunshine Project, power loss can be reduced by half, and by the use of high magnetic field, size/weight can be reduced such as reduction in rotor diameter and reduction in weight by half. Further, as an innovative system, cited are the superconducting magnetic energy storage system (SMES) and flywheel energy storage system. The superconducting magnetic levitation railway, medical use MRI, etc. have also innovativity which is difficult to get in the conventional technology. Effects are also expected of introducing the process development using superconducting magnet such as magnetic separation, electromagnetic metallurgy, electromagnetic agitation and monocrytal growth convection control.

    This survey aims to verify whether recoverable energies can bear the important role of energy source in place of fossil fuels, to probe into problems that may arise in the process of recoverable energy introduction, and to compile suggestions about measures toward their smooth introduction, these by working out an 'ultralong-term world energy supply and demand outlook' valid up to 2100. Various measures to deal with global warming are analyzed by simulation. The study is not to predict what is in store but to metrically describe and present choices and possibilities for the future with a theoretical consistency based on various factors including economic growth, population, demand for energy, magnitude of fossil energy resources, and feasibility and cost of recoverable energies. This study implies that there is not a single, determining policy for solving the global warming problem and that it is important to cope with the problem by resorting to combinations of various means.

    Survey was made on application technologies of next- generation high-density energy beams. For real application of laser power, application to not exciting source of YAG crystal but machining directly is highly efficient. For generation of semiconductor laser high-power coherent beam, phase synchronization and summing are large technological walls. Short pulse, high intensity and high repeatability are also important. Since ultra-short pulse laser ends before heat transfer to the periphery, it is suitable for precise machining, in particular, ultra-fine machining. To use beam sources as tool for production process, development of transmission, focusing and control technologies, and optical fiber and device is indispensable. Applicable fields are as follows: machining (more than pico seconds), surface modification (modification and functionalization of tribo- materials and biocompatible materials), complex machining, fabrication of quantum functional structured materials (thin film, ultra-fine particle), agriculture, ultra-precise measurement, non-destructive measurement, and coherent chemistry in chemical and environment fields.

    Process validation concerns the establishment of the irradiation conditions that will lead to the desired changes of the irradiated product. Process validation therefore establishes the link between absorbed dose and the characteristics of the product, such as degree of crosslinking in a polyethylene tube, prolongation of shelf life of a food product, or degree of sterility of the medical device. Detailed international standards are written for the documentation of radiation sterilization, such as EN 552 and ISO 11137, and the steps of process validation that are described in these standards are discussed in this paper. They include material testing for the documentation of the correct functioning of the product, microbiological testing for selection of the minimum required dose and dose mapping for documentation of attainment of the required dose in all parts of the product. The process validation must be maintained by reviews and repeated measurements as necessary. This paper presents recommendations and guidance for the execution of these components of process validation. (author)

    This book provides a rigorous yet accessible introduction to the theory of stochastic processes. A significant part of the book is devoted to the classic theory of stochastic processes. In turn, it also presents proofs of well-known results, sometimes together with new approaches. Moreover, the book explores topics not previously covered elsewhere, such as distributions of functionals of diffusions stopped at different random times, the Brownian local time, diffusions with jumps, and an invariance principle for random walks and local times. Supported by carefully selected material, the book showcases a wealth of examples that demonstrate how to solve concrete problems by applying theoretical results. It addresses a broad range of applications, focusing on concrete computational techniques rather than on abstract theory. The content presented here is largely self-contained, making it suitable for researchers and graduate students alike.

There is little research on PBM dynamics although its phenomena and mechanism have been widely studied. The PBM was discussed from dynamic viewpoint in this paper. It was found that the primary process of cellular PBM might be the key process of cellular PBM so that the transition rate of cellular molecules can be extended to discuss the dose relationship of PBM. There may be a dose zone in which low intensity LI (LIL at different doses has biological effects similar to each other, so that biological information model of PBM might hold. LIL may self-adaptively modulate a chronic stress until it becomes successful.

    With an objective to develop low-cost and high-efficiency hybrid thin film/sheet solar cells, research and development has been performed. This paper summarizes the achievements in fiscal 1999. The research is related to a hybrid construction, in which the upper cells of amorphous silicon thin film are formed on the lower cells bonded with micro-crystalline silicon thin film relative to a poly-crystalline silicon sheet. In the technology to form the upper cells, a pin-construction using amorphous silicon thin film made by using the plasma CVD process was adopted, whereas an open circuit voltage of 1.45V, a short circuit current of 13.6 mA/cm{sup 2}, and a conversion efficiency of 13.5% were obtained. In the technology to form the substrate for the lower cells, formation of flat silicon thin plate that can be peeled off was identified as a result of adopting the construction in which a graphite substrate is provided on a rotating cooling body of 12-prism type. With regard to the technology to bond and form the lower cells, electrical properties of hetero-bonded cells were discussed, and an open circuit voltage of 0.605V and a conversion efficiency of 14.3% were obtained as a result of enhancing the film quality and optimizing the film thickness.

The study was made in terms of a large-capacity waste-fueled power plant, estimation of the waste amount considering wide-area processing, size of facilities, comparison of four types of combustion furnace, steam condition/seawater cooling/power generating efficiency, etc. As a result, the following were proposed: As to the size of facilities, a capacity as large as possible is recommended in the light of the scale merit of costs of the waste-fueled power plant and final disposal site and the environmental preservation. Concerning the high efficient power generation, recommended are 450degC and 60-80 ata which are steam conditions for coping with high temperature corrosion. In respect to seawater cooling, the adoption is recommended making good use of locational conditions since the output energy increases by approximately 16%. Any furnace types including the fluidized bed furnace are equal. The amount of dioxin becomes below 0.1ng/Nm{sup 3} because of the control of furnace combustion temperature, residence time, catalytic desulfurization facilities, blowing of activated coal into the flue, etc. 172 figs., 78 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)

    It is intended to develop thin film solar cells capable of mass production with high photo-stability and at low cost. Thus, the objective of the present research is to analyze the growth process of micro crystal silicon based thin films, the crystal being a high quality silicon crystal based material, and develop technology to manufacture high-quality micro crystal silicon thin films based on the findings therefrom. It was found that, when silicon source is available in cathode, pure hydrogen plasma forms micro crystal silicon films by using the plasma as a result of the chemical transportation effect from the silicon source. It was revealed that the crystal formation due to hydrogen plasma exposure is performed substantially by the crystals forming the films due to the chemical transportation effect, rather than crystallization in the vicinity of the surface. The crystal formation under this experiment was concluded that the formation takes place during film growth accompanied by diffusion of film forming precursors on the surface on which the film grows. According to the result obtained so far, the most important issue in the future is particularly the control of crystal growing azimuth by reducing the initially formed amorphous layer by controlling the stress in the initial phase for film formation, and by controlling the film forming precursors.

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

    This paper reports the surveys in fiscal 1999 on research and development of the environment harmonizing catalyst technology. The discussion subjects taken up included suppression of discharge of carbon dioxide, catalysts used when manufacturing hydrogen and technology thereof, and environment purifying catalysts to decompose harmful substances, and technology thereof. The roles of catalysts and their technologies are expected in reducing the reforming temperatures, achieving energy saving, and reducing decomposition energy. Furthermore, the catalysts are expected of high activity, long life and low cost. Three themes were selected from the emergency and importance points of view. The themes are, in the consumer field, research and development of efficiency improvement in membrane reactors for reforming low-grade hydrocarbons to structure a technology to manufacture hydrogen for small-size portable fuel cells; and in the industrial field, development of hydrogen and carbon product manufacturing technologies with which CO2 generation is suppressed by means of the catalytic decomposition process. In practice, for such discharged harmful substances as dioxins, PCB and volatile organic compounds (VOC), treating them is the urgent environmental problem, and therefore, the fundamental research was taken up for practical application of the second-generation catalysts of the ultra-violet light and visible light responding type.

    Research and development has been made on technologies to reduce sulfur content in light oil and on optimization of light oil quality. This paper summarizes the achievements in fiscal 2000. In the study of enhancing the desulfurization rate in gas oil deep hydrodesulfurization process, it was found that NiHY zeolite having Ni introduced by using the ion exchange method shows stable activity, whereas the target of sulfur content of 50 ppm or lower was achieved by adding the third constituent and by optimizing the impregnation solution to pH3. In the study of the Ni, Mo/alumina catalyst, the desulfurization activity was enhanced by optimization of carrier pore size to 120 to 140 angstroms and by addition of phosphorus and silica, having the target of sulfur content of 50 ppm or lower achieved. In the research of manufacturing low-sulfur light oil using heavy oil desulfurization and hydrocracking, optimization was performed on the catalyst used in the latter stage of heavy oil desulfurization, and evaluation was given on the performance in combination of commercially available hydrometallation catalyst/middle part HDS catalyst/bottom part HDS catalyst. As a result, achievement of the target of sulfur content in the desulfurized light oil of 300 ppm or lower was verified. Life evaluation test is in continuation on the heavy oil hydrocracking catalyst. (NEDO)

    The aim is to develop a method of processing oxygen concentration distribution in human organs into an image by computed tomography using near infrared rays capable of transmitting through living tissues. Since the photoabsorption spectra of hemoglobin etc. in blood vary according to the degree of their oxidation, an oxygen concentration level is determined by measuring the magnitude of the variation. In the imaging method named in the title, the object is irradiated with picosecond-level near infrared pulses from all directions successively, the pulses after transmission through the object are measured at all directions at a picosecond-level time resolution, and the distribution of pulse scattering and absorption characteristics are subjected to algorithmic calculation, the outcome is converted into oxygen concentration levels, and an image is obtained. A 64-channel time resolution measurement system is constructed, and is applied to living tissue models (phantoms) and animals, and an image is obtained and evaluated. On the basis of the result, a patient is examined for clinical evaluation, and an image reflecting the distribution of variations in hemoglobin oxygen concentration is obtained for the head of the adult patient. A spatial resolution of 1cm is achieved in case of a phantom 10cm in diameter. In the case of 64 channels, measurement takes approximately 20 minutes and mapping image data measurement takes approximately 7 minutes. (NEDO)
