    Technological trends have been compiled on the basis of the agendas of all the six events from the 1st International Conference on Refractories through the UNITECR `95 held in Japan. Although the number of articles presented increased from 52 to 187 during this period, yet there was a remarkable decrease in the number of articles in some fields related to refractories for iron and steel making, the said field involving pig iron melting preparatory treatment and torpedo cars. There is no great change in the number of articles about the MgO-C brick in use for building converters and electric furnaces that are typical kilns, with various countries presenting papers indicating that the brick is the representative of high-performance refractories being used across the world. There is a steady increase in the number of articles related to nonferrous metals, glass, and cement, and attracting attention is the papers concerning incinerators. The number of papers about basic technologies and new testing methods is constant. Attracting attention are papers for example on fine ceramics with its scope of application as refractories spreading, which reflects the technological trends across the world and the circumstances the host countries find themselves under. It is added here that Brazil rich in refractory resources presented many papers at the conference that it hosted. 27 refs., 7 tabs.

    In this article, we present results on the identification and behavioral analysis of social bots in a sample of 542,584 Tweets, collected before and after Japan's 2014 general election. Typical forms of bot activity include massive Retweeting and repeated posting of (nearly) the same message, sometimes used in combination. We focus on the second method and present (1) a case study on several patterns of bot activity, (2) methodological considerations on the automatic identification of such patterns and the prerequisite near-duplicate detection, and (3) we give qualitative insights into the purposes behind the usage of social/political bots. We argue that it was in the latency of the semi-public sphere of social media-and not in the visible or manifest public sphere (official campaign platform, mass media)-where Shinzō Abe's hidden nationalist agenda interlocked and overlapped with the one propagated by organizations such as Nippon Kaigi and Internet right-wingers (netto uyo) during the election campaign, the latter potentially forming an enormous online support army of Abe's agenda.

    This synopsis outlines the Japanese guideline Version 2.0 for the data acquisition protocol of oncology FDG-PET/CT scans that was created by a joint task force of the Japanese Society of Nuclear Medicine Technology, the Japanese Society of Nuclear Medicine and the Japanese Council of PET Imaging, and was published in Kakuigaku-Gijutsu 2013; 33:377-420 in Japanese. The guideline aims at standardizing the PET image quality among PET centers and different PET camera models by providing criteria for the IEC body phantom image quality as well as for the patient PET image quality based on the noise equivalent count (NEC), NEC density and liver signal-to-noise ratio, so that the appropriate scanning parameters can be determined for each PET camera. This Version 2.0 covers issues that were not focused on in Version 1.0, including the accuracy of the standardized uptake value (SUV), effect of body size together with adjustment of scanning duration, and time-of-flight (TOF) reconstruction technique. Version 2.0 also presents data acquired with new PET camera models that were not tested in Version 1.0. Reference values for physical indicators of phantom image quality have been updated as well.

    Two kinds of Japanese guidelines for the data acquisition protocol of oncology fluoro-D-glucose-positron emission tomography (FDG-PET)/computed tomography (CT) scans were created by the joint task force of the Japanese Society of Nuclear Medicine Technology (JSNMT) and the Japanese Society of Nuclear Medicine (JSNM), and published in Kakuigaku-Gijutsu 27(5): 425-456, 2007 and 29(2): 195-235, 2009. These guidelines aim to standardize PET image quality among facilities and different PET/CT scanner models. The objective of this study was to develop a personal computer-based performance measurement and image quality processor for the two kinds of Japanese guidelines for oncology (18)F-FDG PET/CT scans. We call this software package the "PET quality control tool" (PETquact). Microsoft Corporation's Windows(™) is used as the operating system for PETquact, which requires 1070×720 image resolution and includes 12 different applications. The accuracy was examined for numerous applications of PETquact. For example, in the sensitivity application, the system sensitivity measurement results were equivalent when comparing two PET sinograms obtained from the PETquact and the report. PETquact is suited for analysis of the two kinds of Japanese guideline, and it shows excellent spec to performance measurements and image quality analysis. PETquact can be used at any facility if the software package is installed on a laptop computer.

    The Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP3) will be held in Kyoto in December 1997. Described herein are the current status and issues of the convention. USA and Japan, which hold important keys to set up the abatement target, have issued no proposals concretely at the current AGBM (Ad-hoc Group Berlin Mandate) 7, and the conference for the concrete targets will be decided in the next AGBM 8 to be held in October. The final target will be set by the ministerial segment of COP3, because the negotiations for the treaty are political in nature. USA proposes reduction at a uniform, realistic rate, and Japan proposes reduction at a uniform rate or setting up the emission target per capita, each being different from reduction at a much higher uniform rate proposed by EU. Within EU, however, 10% out of 15% reduction rate it proposes is agreed by the member countries, and the remaining rate of % may not be agreed. It is necessary for the advanced parties to set up realistic and legally binding solutions, including ratification by USA, which can persuade the developing countries. tab.1

    1994-12-28

    The type and applications, manufacturing method, characteristics, road pavement etc. of asphalt were introduced. Among the petroleum asphalts, straight asphalt is used for road pavement,industry, and combustion, while blown asphalt is mainly used for the waterproofness of a building. Also, the demand for modified asphalt where rubber or thermoplastic elastomer was mixed is increasing. Straight asphalt is obtained by allowing atmospheric distillation tower bottom oil to be subjected to reduced pressure distillation and drawing reduced pressure gas oil and lubrication oil cut. Blown asphalt is produced by the oxidation dehydrogeneration and condensation polymerization reaction of soft straight asphalt. Rheology characteristics of asphalt are expressed by stiffness, relaxation elastic modulus, complex elastic modulus, etc. Also, asphalt has high electrical dielectric properties. Asphalt pavement has functions for dispersing traffic load and then transferring it to a lower layer, for resisting wear and cracking, and for preventing penetration of rainwater. 30 refs., 5 figs., 4 tabs.

    This is a proceedings of the papers made public in the 33rd (fiscal 1996) Coal Science Conference held by the Japan Institute of Energy. The number of the papers included is 82. The processes such as coal liquefaction, coal gasification and pyrolysis are largely influenced by reaction of the carbon compound in coal. However, coal, which is different in reaction characteristics depending on its producing area, is a comprehensive compound. Therefore, the trial has been made for clarifying the molecular structure and skeleton. In the sense, the following papers are taken notice of: Suzuki and others` Estimation for origin of coals by biomaker analysis; Sugimoto and others` Change of unit skeletons during the artificial coalification; Hirado and others` Study on the correlation between chemical and mineral composition of coal ashes; Okawa and others` Coal structure construction system with construction knowledge and partial energy evaluation; Kanbayashi and others` Analysis of the relationship between coal properties and liquefaction characteristics by using the coal database.

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

    This paper reviews the current status from the standpoint of chemical engineers facing the coming of the 21st century, and surveys the paradigm for new scientific technologies. The criticism is mixed with unique opinions everywhere, such as `departure of students from scientific and engineering faculties is none other than the result of a market principle`, `national burden of trillions of yens should not be spent only under a justice of advancement of the science`, and `the global civilization itself has no other way but to change from the conventional expansive development type of the western country style to the internal development type of the oriental country style`. Values that define the paradigm for new scientific technologies may include such keywords as saturation in technology, baseless expansion of research projects, criticism on science, market principle, and centering human being. It should be looked at seriously that profit from research and development should exceed the cast invested therein in the future, and scientific technologies that serve truly the society should be aimed at. These efforts will result in one of the large pillars that support the future in which creation of new functions is aimed at as a result of structuring the new systems. Trying to overcome the environmental problems is one of them.

    The paper stated mostly topics from special lectures. Composite materials have a lot of potentialities, and there are larger expectations in flexible and high-strength soft composites rather than the conventional high rigidity ones. As to micro-machines, the problems are on mechanical property of the element, environment/friction/fracture/life, etc. and the evaluation method of the characteristics was studied. Concerning the research and development of the intellectual structure system, the introductive study has entered the second year. Ultimately, structures have functions similar to those of the living organism had, and conduct self-diagnosis, self-repair and autonomous-response. Railroad structures receive regular inspections according to the rule, and a half of the objects for the inspection are cracks, unbonding and weathering of concrete. With the Hanshin Awaji great earthquake especially, the anti-earthquake reinforcement has been expedited. In various kinds of materials, the finer the crystal particle becomes, the greater the high temperature deforming ability becomes. When the particle size is below the critical particle size, it shows superplasticity. The study is advancing. As to high density secondary batteries, introduced especially were Ni-hydrogen batteries and Li batteries.

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a steel technology field. Japanese steel industry should correspond to requirements of the international economic society as the top runner. Although it is now difficult to suppose a basic technology innovation, stable supply of basic materials is necessary for peripheral industries. The basic raw material technology is the basis of domestic and overseas socio- economic activities. The technology development support system to retain the world-wide leadership of Japanese industries is a strategic issue. Preparation of cooperative R and D bases of industry, academia and government along a national policy is important. Strong promotion of such national projects is also essential as global environment problem, positive use of advanced information tools, development of technologies and products of unexplored fields, and development of new products and demand creation according to social needs. Such measures along social requirements are also important as raw material development to double an energy efficiency, and the policy and system to construct a recycling society and living spaces.

    Research and development have been carried out on a high-level water purifying system using ozone and activated charcoals to supply drinking water free of carcinogenic matters and odors. This system comprises a system to utilize ozone by using silent discharge and oxygen enriching device, and a living organism/activated charcoal treatment system. The latter system utilizes living organisms deposited on activated charcoal surfaces to remove polluting substances including ammonia. The treatment experimenting equipment comprises an ozone generating system, an ozone treating column, an activated charcoal treating column, an ozone/activated charcoal control device, and a water amount and quality measuring system. An experiment was carried out using an experimental plant with a capacity of 20 m[sup 3]/day on water taken from the sedimentation process at an actual water purifying plant. As a result, trihalomethane formation potential was removed at about 40% in the ozone treatment, and at 70% in the whole treatment combining the ozone and living organism/activated charcoal treatments. For parameterization of palatability of water, a method is being studied that utilizes nuclear magnetic resonance to investigate degrees of water cluster. The method is regarded promising. 1 ref., 4 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.

    Modern apparel industries are required to supply many kinds of products corresponding to various needs of consumers. Among consumers' needs, comfortableness to wear such as size-fitness is primarily important. To facilitate apparel industries, it is expected to develop a new technology of pattern designing of comfortable garment and measuring garment pressure distribution. Our research is aimed at developing technology that uses computer simulation to predict and evaluate wear comfort, including size suitability, without the need to actually sew up a garment. First, we developed a basic system to predict wearing silhouette, garment pressure, and ease looseness of the garment. Using this system, we carried on the following study. The 3-dimensional distributions of the garment pressure and ease looseness were reversely mapped on the paper pattern in order to indicate the preferable modification. The system was extended for several poses, e.g. twist, bend. From various parameters, we examined the factors of garment pressure and ease looseness. In addition, we selected the parameters for the size-fit indicators and investigated size-fit evaluation indicators. (author)

    The paper described the results of the survey of the fine ceramics technology field relating to the FY 1999 long-term energy technology strategy. The fine ceramics industry is a new industry for which the future development is expected. It has far-reaching effects on other industries. Japan has the advantage over other countries. As subjects to remarkably develop the industry, needed are the long-term basic preparation which promotes technology innovation such as the promotion of the fundamental/creative R and D, construction of an industry/university liaison system, and arrangement of the intellectual base. Preparation of the competitive environment and promotion of policies paying attention to the market are needed which make the development under the private control by creative study/corporate activities possible. Also important are the demonstration of leadership and secure international competitive force in the light of Japan's international position. For the private-control development, the role and course of various groups should be made clear from a long-term aspect. It is desirable that university/government will newly develop innovative technology, and industry will make the present technology force more developmental and competitive. Support from the nation is requested for researches large in scale. (NEDO)

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of an aircraft technology field. In an aircraft field, since the major theme is application of new technologies to new airframe development, with joining in international cooperative development of aircraft, Japanese initiative development of airframes based on the domestic market demands and profitability should be started as early as possible. Because there is no airframe development by only one country including U.S.A., Japan is profitable to unite with some overseas companies, and invest selectively in specific leading fields. Positive technical support to safety, reliability, comfort and environment harmony are also important. More important theme than establishment of elementary technologies is preparation of an integrated flight demonstration system to expand application chances of development results, and preparation of various test facilities for tests required during development activities. Application of information technologies to the whole aircraft industry, and organic cooperation between the private and public sectors are also important. (NEDO)

    The survey/study were conducted to contribute to proposing technology strategies such as the analysis of the present state of technical competitive force and the forecast in the airplane technology field. In future airplane industry, to meet the requests/restrictions from the society in the international airplane industry in the recent years, it is predicted that technology innovation will advance centering on the following four fields: next generation airplane technology to enable the innovative cost reduction in development/production, technology to realize the substantial reduction in flight cost of airline, technology to enhance reliability for the next generation flight which meets the multi-frequency flight/increasing demand for small plane, and airplane frontier technology. Moreover, regulations especially on noise, CO2 reduction and NOx reduction are becoming very strict internationally because of the increasing concern about global environmental problems. It is urgently needed to establish technology to cope with these trends. As the comprehensive strategy, the following are considered: development of airframe under the leadership of Japan and securing of the demand, efficient arrangement and operation of large-scale experimental facilities, IT adoption to the airplane industry, organic cooperation by industry/university/government, etc. (NEDO)

    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.

Development of the photon technology aims at the modification of bonding conditions of substances by quantum energy of photon, and the new process technology for generating ultra- high temperature and pressure fields by concentrating photon on a minute region. Photon technology contributes to not only the conventional mechanical and thermal forming and removal machining but also function added machining (photon machining) in quantum level and new machining technology ranging from macro- to micro-machining, creating a new industrial field. This technology extends various fields from the basis of physics and chemistry to new bonding technology. Development of a compact high-quality high-power high-efficiency photon source, and advanced photon transmission technology are necessary. The basic explication of an unsolved physicochemical phenomenon related to photon and substance, and development of related application technologies are essential. 328 refs., 147 figs., 13 tabs.

    Remarkable progress has been made in superconducting technology recently. This paper describes the details and technical features of every cooling type of practical superconducting magnet (SCM), including the SCM for magnetic resonance imaging (MRI), SCM for semiconductor pulling devices, high-field SCM, SCM for magnetically confined plasma devices, and SCM for particle detectors. Commercial production of pool-boil-cooled SCMs has been realized by reducing helium evaporation and decreasing the frequency of helium pouring. The development of forced-cooled SCMs has made it possible to build large SCMs. Moreover, the development of the 4 K-GM refrigerator has enabled liquid-helium-free SCMs to be introduced. Since this type of SCM can be operated merely by turning on a switch, SCMs are expected to come into more widespread use. 7 refs., 1 fig.

    For the application of photon to industrial technologies, in particular, a hard photon technology was surveyed which uses photon beams of 0.1-200nm in wavelength. Its features such as selective atom reaction, dense inner shell excitation and spacial high resolution by quantum energy are expected to provide innovative techniques for various field such as fine machining, material synthesis and advanced inspection technology. This wavelength region has been hardly utilized for industrial fields because of poor development of suitable photon sources and optical devices. The developmental meaning, usable time and issue of a hard photon reduction lithography were surveyed as lithography in ultra-fine region below 0.1{mu}m. On hard photon analysis/evaluation technology, the industrial use of analysis, measurement and evaluation technologies by micro-beam was viewed, and optimum photon sources and optical systems were surveyed. Prediction of surface and surface layer modification by inner shell excitation, the future trend of this process and development of a vacuum ultraviolet light source were also surveyed. 383 refs., 153 figs., 17 tabs.

    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.

Rapid prototyping means the combination of technology forming directly the physical model from CAD data. It is a summarization of technology composed of design assistant technology, model production technology, and integration technology. In 1980`s, 3D System Corp. proposed the stereo lithography. Since then its research and development were promptly carried out as for the technology of rapid formation o physical model. Resultantly, it became possible to fabricate the model designed by the three dimensional CAD within a day using a rapid prototyping system. This can be roughly divided into the following three: (1) stereo lithography, (2) method of melting and hardening by laser irradiation of the powder plastic and wax, (3) 3D-printing method consisting of selectively coating of ceramic powder with binder. 4 refs., 3 figs.

    According to the trend of car suspensions announced in 1989, not only sports cars but also sedans have extensively applied a multi-link type and a double-wishbone type which are to improve operation stability and comfortableness by reexamining all their fundamental structures. Active suspensions with electronic control have been put to practical use and adopted for the first time to mass-produced cars such as INFINITI'' and CELICA''. Concerning steerings, most types of light cars are now equipped with power steerings. Moreover, application of air bags has increased, and safety has been improved by commercialization of the first mechanical air bags in addition to the conventional electrical ones. As for brakes, more anti-lock brakes have been used for 4WD cars and low-displacement cars. Motorcars with a traction control system have consequently increased. Thus both the anti-lock brakes and the traction control system are contributing to the improvement in safety. 17 figs., 2 tabs.

    It may be intended that CWM is manufactured in areas near coal producing areas in overseas countries and imported as a product requiring lower handling cost than in bulk products. In order to achieve this idea, it is necessary to establish a distribution and relaying system for product transportation inside and outside the country, including relaying bases for receiving, loading and storing the product. This paper reports results of the demonstration tests performed since 1992 to 1996. In the tests, CWM made from Chinese coals was transported from Shijiu Port to the Hibiki relaying base in the city of Kita-Kyushu on 5000 DWT ocean vessels, unloaded, stored, and loaded again on 700 DWT domestic vessels for distribution to users. Since the inauguration of transportations, 40,000 tons of CWM were delivered yearly to the Okayama plant of Tayca Company, and about 20,000 tons to the Mizushima power plant of the Chubu Electric Power Company over a period from 1995 to 1996. During the period, a number of findings were acquired in different aspects, including quality control of incoming and outgoing CWM, stability in quantity and properties, loading and unloading works, and transportation. Although reduction in subsidence during transportation and storage was indicated desirable, the practical applicability was verified for the relaying system as a whole. 4 refs., 15 figs., 3 tabs.

    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.

    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)

    The paper made a fundamental investigation to promote historical succession and creative use of the industrial scientific technology. As for the wind power generation, the large-scaling became centralized wind power plants, and the downsizing became the distribution to remote areas. 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.

    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.

    The aim is to develop and popularize techniques relating to geological information such as thermal history. The efforts center about the application of a now-available core fracture measuring system to developed geothermal fields and about the development of new technologies. The measuring system is applied to some core cuttings collected from five boreholes in the Akinomiya district, Akita Prefecture, and the system is used for (1) the evaluation of homogenization temperatures of inclusions in the fluid, (2) the measurement of the points of melting from ice of inclusions in the fluid, and (3) the implementation of laser Raman spectroscopy. Under item (1), it is found that the minimum homogenization temperature of quartz phenocryst in the mother rock or of low-salinity fluid inclusion in a quartz vein is near the current subsurface temperature and that subsurface and reservoir temperatures may be known by evaluating their homogenization temperature. Under item (2), it is found that the NaCl equivalent salinity is distributed in the range of 0.0 to 25wt% and that, in this connection, there is difference between a fluid in a fluid flow and a fluid spurting as thermal water in the Akinomiya district. Under item (3), CO2, N{sub 2}, and CH{sub 4} are detected in most of the boreholes.

(1) On electromagnetic casting/once FZ bath method, a Si single crystal of 600mm long was successfully obtained by improvement of power source frequency and furnace parts. High carbon content resulted in no single crystal including solids. In undoped electromagnetic casting ingots, resistivities over 1500ohm-cm were obtained because of effective preventive measures from contaminants. (2) On electromagnetic melting CZ method, since vibration and temperature control of melt surface by magnetic shield was insufficient for stable pulling of single crystals, its practical use was hopeless. (3) On electron beam melting CZ method, a Si single crystal of 25mm in diameter was obtained by preventive measures from evaporation of Si and influence of deposits, and improved uniform deposition distribution in a furnace. The oscillation circuit constant of power source, and water-cooling copper crucible structure were also analyzed for the optimum design of electromagnetic melting furnaces. 3 figs., 1 tab.

    The project aims to establish basic technologies for the mass culture of cells by utilizing the features of animal cells, which will enable a large, stable supply of fine chemicals such as highly functional physiologically active proteins whose industrial production the conventional technique of synthesis fails to realize. For this purpose, efforts are exerted to select cells which are capable of producing target substances, to breed highly productive strains, to develop a serumless medium that satisfies demands for an all-purpose feature and heat sterilization, and to develop technologies of high-density culture and effective refining, etc. Some DNA (deoxyribonucleic acid) recombination technologies are also resorted to. As the result, a high-density culture of 2 times 10{sup 8} cells/ml has become available. Production is now feasible of various differentiation-inducing elements such as monoclonal antibodies with anti-HB virus activity, DIF, etc. Furthermore, cooperation with the Tsukuba University leads to the discovery of a novel vasopressor peptide (endothelin). The heat sterilization accepting serumless medium, which is put to practical use as the first of the kind in the world under this research and development project, contributes to the advancement of basic studies about cell biology.

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

    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.

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

    This paper describes features of high power YAG cutting. The optical fiber transmission YAG laser machining system has some advantages in which optical path length compensation unit is not required and measures for low power loss and dust are not required, when compared with the CO2 laser system. Its application to the cutting of stainless steel plates has attracted attention. Cutting tests of SUS304 were conducted using high power YAG laser. Cutting of SUS304 plate with a thickness of 40 mm could be successfully done at the power of 3.5 kW. Cutting tests of SUS304 pipes with a thickness of 8 mm in water under the depth of 20 m were also conducted using air as assist gas at the power of 2.5 kW. Excellent results were obtained without scale deposition. For the tests by the composite beam using 3 kW and 4 kW systems, SUS304 plate with a thickness of 50 mm could be cut at the cutting speed of 0.1 m/min. Laser cutting of pipes from the internal surface was conducted using a newly developed small machining head which can rotate in the peripheral direction. Excellent quality for welding was confirmed. Cutting speed and plate thickness were improved by combining water jet cutter and YAG laser unit. 6 refs., 10 figs.

    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.

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

    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)

(1) On the fabrication technology of high-quality Si thin films, the new equipment was studied which allows uniform stable melting recrystallization over a large area. The new equipment adopted a heating method based on RTP system, and is now under adjustment. (2) On the fabrication technology of light/carrier confinement structure, degradation of hydrogen-treated thin film Si solar cells by light irradiation was examined. As a result, since any characteristic degradation was not found even by long time light irradiation, the high quality of the cells was confirmed regardless of hydrogen-treatment. Fabrication of stable reproducible fine texture structure became possible by using fabrication technology of light confinement structure by texture treatment of cell surfaces. (3) On low-cost process technology, design by VEST process, estimation of cell characteristics by simulation, and characteristics of prototype cells were reported. 33 figs., 1 tab.

    This paper reports the study results on technological development for qualitative improvement of a-Si solar cells after initial degradation in fiscal 1994. On the fabrication technology of light-stable a-Si films, the film formation method possible to control combined hydrogen by repetitive formation/treatment was developed. The obtained high-quality light-stable a-Si film was featured by low defect density in a wide optical band gap range, and defect density of nearly 3 {times} 10{sup 16}/cm{sup -3} after light irradiation. The light degradation rate of the cell where the a-Si film was applied to i layer was relatively stable by 10% or less. The a-Si/a-Si double-layer tandem cell fabricated by this technology produced a high conversion efficiency of 10.5%. By applying {mu}c-Si material to photoactive layer as narrow band gap material, the cell with optical sensitivity even in long wavelength ranges more than 1000nm was obtained. The a-Si/{mu}c-Si double-layer tandem cell produced an initial efficiency of 8.0% and an efficiency after degradation of 7.5%. 12 figs., 3 tabs.

    A report was made on the 1998 results concerning technological development of super metal. In the 'research and development of super metal', metallurgical examination has been made on crystal grain super refining process using a machining simulator, with studies carried out on crystal grain refining by utilizing large-strain deformation with more than 50% deformation for a single pass and a diploid structure. As a result, it was found that the crystal grain size can be refined to approximately 1{mu}m. Consequently, in fiscal 1998, a high-speed large reduction rolling test equipment was developed capable of rendering a sheathing technology in a mechanically testable size by a rolling method. This test equipment has such capacity as the maximum load of 1,000 ton and the maximum torque of 95 ton/m and is a rolling mill whose scale is largest in the nation on the laboratory level. The rolling speed can be 120mpm, a very fast speed for a large sized rolling mill. Moreover, equipped with an immediate water cooling facility adjacent to the rolls and an automatic operating system for example, it is a high function rolling mill capable of cooling and rolling that render the complex and delicate sheathing technology of super metal.

    As carbon dioxide-related environmental measures, method was explained to chemically convert and utilize carbon dioxide. Synthesis is possible of methanol, carbon monoxide, different carbohydrates, etc. by catalytic hydrogenation of carbon dioxide, using hydrogen produced by the electrolysis of water. Task consists of heightening in both convertibility and selectivity, and abundant supply of low cost hydrogen. Methane, alcohol, etc. can be synthesized by electrochemical reducion of carbon dioxide. Because of effectively inserting multiple electron, discssion is being made of catalyst, intergrated with electrode, and electron transmitter. The photoelectrochemical reduction of carbon dioxide can be also made by utilizing photoelectric current, generated upon photoradiation on the semiconductive electrode. However, task consists of heightening in both efficiency and selectivity. Photochemical reduction of carbon dioxide, actually made by green plant, consists of oxidationlike decomposition of water and reduction of carbon dioxide. Both those reactions are skillfully separated by intermediation of very quick electron transmission system. Reduction is being studied with semiconductor, metallic colloid, enzyme, metallic complex and other various catalysts. 10 refs., 3 figs., 4 tabs.

    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.

    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.

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

    This paper presents new technologies of the railway bridges in Hokuriku Shinkansen. Hokuriku Shinkansen of 117km between Takasaki and Nagano is a part of Shinkansen connecting Tokyo with Nagano by nearly 1.5 hours. Its construction is in promotion under severe financial condition, and cost reduction is an essential target. Among the concrete bridges in this section, Kirizumigawa bridge, a prestressed concrete strutted 3-span continuous beam bridge, adopted a lowering erection method for its slant pier. In this method featured by high safety and profitability, the rib component of a concrete arch bridge is vertically erected on a arch support, and installed by swinging it toward the central span. In addition, a cantilever method was adopted to keep the scenery of a national park. Daini Chikumagawa bridge with the longest span of 133.9m among concrete railway bridges is the first cable-stayed prestressed concrete bridge in Shinkansen. Yashiro Minami and Kita bridges of 105m and 90m in central span are the extradosed bridges which were adopted as optimum structure for lowering the beam height of meddle-sized railway bridges. 3 refs., 12 figs., 2 tabs.

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

    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)

    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)

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a human process ware (HPW) field on electronic information. Although the current HPW industry is not yet complete, various technologies concerned are being stored, and the HPW industry is expected as new major industry for home and personal information equipment. As factors hindering technological innovation in Japan, the incomplete market, poor cooperation between industry and government, ambiguous role of university, and poor standardization were pointed out.

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

    To evaluate geothermal reservoirs in the initial stage of development, to keep stable output in service operation, and to develop a technology effective for extraction from peripheral reservoirs, study was made on a reservoir variation prediction technique, in particular, a modeling support technique. This paper describes the result in fiscal 1997. Underground temperature estimation technique using homogenization temperatures of fluid inclusions among core fault system measurement systems was applied to Wasabizawa field. The effect of stretching is important to estimate reservoir temperatures, and use of a minimum homogenization temperature of fluid inclusions in quartz was suitable. Even in the case of no quartz in hydrothermal veins, measured data of quartz (secondary fluid inclusion) in parent rocks adjacent to hydrothermal veins well agreed with measured temperature data. The developmental possibility of a new modeling support technique was confirmed enough through collection of documents and information. Based on the result, measurement equipment suitable for R and D was selected, and a measurement system was established through preliminary experiments. 39 refs., 35 figs., 6 tabs.

    As for their outputs, the 3kW separately-excited and self-excited photovoltaic power plants yield daily averages of 7.8kWh and 6.9kWh, respectively, and this means that the self-excited type is inferior to the separately-excited type in terms of conversion efficiency. Automatic measuring devices for photovoltaic characteristics are installed at Sapporo, Sendai, Nagoya, and Miyazaki, which will elucidate regional difference in photovoltaic characteristics. A simulation of photovoltaic characteristics is performed and the resultant value is compared with the yield of an experimental 3kW system, and the result of the comparison is found reasonable. Cell arrays are subjected to investigation for configurations lowest in output loss for the respective shadow patterns. Harmonic characteristics are analyzed under plural-interconnection circumstances. Studies are made to miniaturize and simplify system constituents, and it is found that a 3-hour storage is proper for a 3kW-class storage battery. It is also found that a self-excited type suffers less voltage fluctuation in interconnected operation on a small short-circuit capacity system. Possibilities are that independent operation is started when output is larger than load, which is to be detected by checking changes in phase, frequency, etc. Array configuration, arresters, and shielding wires are taken up for the study of measures to cope with direct thunder strokes.

    The software of automotive control systems has become increasingly large and complex. High level languages (primarily C) and the compilers become more important to reduce coding time. Most compilers represent real number in the floating point format specified by IEEE standard 754. Most microprocessors in the automotive industry have no hardware for the operation using the IEEE standard due to the cost requirements, resulting in the slow execution speed and large code size. Alternative formats to increase execution speed and reduce code size are proposed. Experimental results for the alternative formats show the improvement in execution speed and code size. 4 refs., 3 figs., 2 tabs.

    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)

In the research of a large-area light absorbing layer manufacturing technology, investigation was made on light absorbing layers in manufacturing sub-modules with a size of 30 cm times 30 cm. With regard to the temperature condition in the light absorbing layer forming process, it was found that the cooling rate affects particularly the adhesion in the connecting interface of the light absorbing layer and the Mo rear electrode layer. In addition, it was revealed that the sulfur take-in amount can be increases by extending the retention time at the sulfurizing temperature and by decreasing the temperature to turn the gas phase into selenium. In the research of elementary technologies to establish the mass production process, developments were performed on the high-resistance buffer layer manufacturing technology, the high-quality window layer film manufacturing technology, and the technology to manufacture rear electrode layer made of high-quality metals.

    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)

    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)

    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. Reference is made to an example of disinfection work implemented at a water purification plant of Milwaukie City, United States. 9 refs., 6 figs., 4 tabs.

    With developing countries (APEC countries) as the main objects, investigations were carried out to issue environmental technology transfer information that Japan has accumulated, and advance exchanges of technical information with persons related inside and outside Japan. As a result of the investigations, it was found that the environmental technology information that serves more effectively for the developing countries is the technical information that has been developed by repeating improvements, has provided actual results in work sites, and is actually used, rather than the state-of-art technologies. Based on this result, business entities having factories and operation centers located in Mie Prefecture and the city of Yokkaichi were asked to provide data for the actually used environmental technologies. Out of 51 items provided by 17 companies, nine items were selected to be used as prototype database materials for an information network. The objects of information sources will be expanded to a nationwide scale in the future to improve the contents of the database. Problems of handling information copyrights and technical know-hows were presented in the course of data collection, urging the necessity of due considerations on the matter. Necessity was indicated on maintenance and management of data base as well as its quantitative expansion. 1 ref., 4 figs.

    Recently, artificial taste sensors or smell sensors that simulate the biological recognition mechanism were developed. This paper describes a smell sensor using natural and artificial fats as the molecule recognizing material and the crystal oscillator or SAW (Surface Acoustic Wave) device as the transducer. The paper also describes the results of the experiments made on the sensor. This sensor consists of 20 LB (Languivir-Blodgett) layers of several types of natural fats on the SAW device. Natural fats on the surface of the crystal oscillator were coated and the response to smelling substances was checked. The result indicates that the response is almost proportional to concentration, and that alcoholic smells can be recognized. To check receiving signal from the sensor system related to absorption and the absorption speed and converting it into higher order information, experiments were conducted to convert data into characters through the neutral network. Though there are still issues of practical use, it was verified that these techniques are effective. 9 refs., 6 figs., 1 tab.

    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)

    This paper describes R and D on creation technique of novel advanced enzymes. 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. Research work was also promoted by various organizations to develop an accelerated formation technology of bio-functions. 68 refs., 51 figs., 14 tabs.

    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%.

    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.

    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.

In the milling sequence, Primary Roughing, which cut out 90% of the stock, should be more and more performable. So we established Tilt-Plunging and Curve-Fit Spiral Cutting techniques. These techniques will reduce lateral force to the tool, and make remains more small. With the techniques, we reduced both machining and NCdata preparing time to one half. 1 ref., 14 figs.

    In connection with contamination of soil and ground water, a survey was made on domestic patent information and existing literature or the like, in view of remediation technologies capable of in si-tu or on-site treatment, with arrangement and classification carried out by the method of cleaning contaminants. Arranged and classified were 209 pieces in the patent information, and 145 pieces in the literature from Geo-Environmental Protection Center, an incorporated body. In the methods of extracting contaminants from under the ground, the majority was the methods of pumping up ground water and those of excavating and removing. In the methods of cleaning contaminants, those of 'separation by heat', 'separation/decomposition method using water' and 'suction of gases' are found roughly in equal numbers. In the trend of the patent information, remediation technologies have started in 1990's, while bio-remediation as well as technologies of separation/decomposition through water is still increasing in the number of applications. Meantime, solidification technologies reached a peak around 1998 and have been decreasing in recent years. In the technologies of late, combinations of plural cleaning methods are also seen for the purpose of dealing with contamination with high to low concentration and compound contamination including organo-chloric compounds, heavy metals, etc. (NEDO)

    Due to the rapid economy growth and industry development in China, the map of industry and economy in Asian countries has been greatly changing. The technology, which has supported Japan's industrial development, is characterized by the improvements of original technologies introduced from Europe and the United States. On the other hand, Korea has problems of creating the original and individual production technology and its basis. The industrial technology in China at present has problems which are accompanied with the conversion from the planned economy system to the market economy system. However, Chinese people having a tradition of 'link of three parts' seem to understand the Japanese style management policy well. Japan has played a role as 'world's center of manufacturing' by using its excellent production technology. In the future, China is considered to play a role as the 'world's center of manufacturing,' due to its huge domestic market, cheap and rich manpower, and excellent potential capacity of industrial technology. In Japan, it is emphasized that an industrial society system should be reconstructed, in which excellent individuality and talent can be made good use of. 6 refs., 1 fig.

    The paper described the results of the survey of the formed raw material field in relation to the FY 1999 long-term energy technology strategy. In the advancing international specialization, efforts are being made for the secure basic base technology force and cost reduction required for competition, and at the same time the aim is not to retain/improve all the formed raw material technologies, but to discriminate the materials in the aspects except the cost. By promoting the reformation into the proposed type industry, it is necessary to work out the bold strategy including the review of the system/structure for promoting the strategic technology innovation by aiming at the important formed raw material technology which can be a life line for the assembly industry, in particular. Concretely, the comprehensive technology system which concentrated a variety of engineering knowledge/information was constructed. The system is shifted to the one that adopted information/communication technology. The conversion in the early time to the proposed type industry is attempted. Japan acquires capability for heightening the level of technology, by which Japan will continue leading the formed raw material technology to the world's top level. Japan realizes the network consisting of the industry, university and government. The environment is realized where new personnel will naturally enter the formed raw material industry and bottom up the total technology force. (NEDO)

    This paper explains the latest situation in hardware technologies to realize the demand side management, divided into the following technologies: communications technology, measurement technology, client information system technology, load controlling technology, home automation technology, and energy storing and saving technologies. Speaking of the communications technology, information exchange between the supply side and the demand side is important in the demand side management, whereas a technology intended of automatic power distribution and automatic meter-reading is advancing in development. The technology covers transmissions using from power lines and telephone lines to optical cables and wireless communications. Power line communications using power transmission lines as communication lines are simple and economical, but weak against noise, and not suitable for long-distance communications. Wireless communications have been drawing attentions along with the development of mobile communication device technologies. These technologies will give benefits to electric power companies in the initial stage of their use, such as for load investigation and general automation in power distribution. They would shift to benefiting users in about 2010 covering from security information such as about power interruption to publicity information and educations. 8 refs., 8 figs., 1 tab.

    Light Emitting Diode (LED) has not only an excellent display function for the luminescent device but also a superior feature without other lamps as light source for plant growth. It was National Aeronautics and Space Administration (NASA) to find out such merit for this light source for plant growth and try at first to use for plant growth at the space. They began to examine the LED application to the light source for the plant growth at the space since a stage at high cost of the LED, to develop some researches centered at cultivation of lettuce, wheat, and others. Finding out future possibility of cost-down of the LEDs on the cost/performance and large merits of the LEDs for control of the plant growth and plant physiology, authors have conducted some cultivation experiments of the plants using the LEDs for light source some years ago. In this papers, characterizations, actual possibility, and future developments of the LEDs for the light sources of the plant growth, are introduced. 5 refs., 4 figs.

    This paper describes chlorination substituting disinfection technologies used in water purification systems. Chloramine treatment is regarded as effective in reducing trihalomethane (THM). Chlorine is injected in the initial stage in the form of free chlorine to disinfect pathogenic microorganisms in a short time, which is then added with ammonia to convert it into chloramine for further utilization. Chlorine dioxide has not been used in Japan, but introduced in Europe and America to treat THM. Ozone has the strongest oxidizing power, and is used for disinfection, virus inactivation, decomposition of THM precursors, and removal of fungus odor. The ozone treatment will produce aldehyde if an organic matter is present, but aldehyde can be removed by treatment using organismic activated carbon. Ultraviolet ray treatment has an advantage of being difficult of producing byproducts. This system was experimentally compared with free chlorine treatment on disinfection effect, mutagenicity, suppression of producing THM byproducts, and odor removal. In order to assure reliability of microorganismic and chemical safety in tap water supply systems, assurance by considering the entire system is important, not only by operating the disinfection units, but also combining such physical water purifying technologies as coagulation, sedimentation, filtration, and membrane treatment. The use of chlorine substituting disinfectants is also a part of the conception. 6 refs., 8 figs., 5 tabs.

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

    The key technology that can effectively support the sharing of each information such as documents, data, and know-how was rearranged to clarify how to utilize it for constructing an electronic information sharing system. The key technology that supports the sharing of electronic information was rearranged from the viewpoint of information gathering, information rearrangement, and information utilization. The reduction in cost for information gathering and rearrangement is indispensable to the promotion of much information sharing. However, each automation method presently causes the deterioration in quality of the rearranged information and the increase in cost for information utilization. To realize a practical electronic information sharing system, it is important to combine the key technologies properly so that the total cost balance of information gathering and information utilization is improved. Therefore, the combination of character recognition by OCR and unpreciseness retrieval, and the complementary combination of automatic document sorting, based on multiple incomplete rearrangement systems, and multiple sorting menus were proposed. 23 refs., 5 figs., 2 tabs.

    Because the prestressed concrete (PC) cable-stayed bridges combine the distinctive features such as a rationality of the structure or a structural beauty, it will not stay on a development of the technologies to make them longer and larger, and a rationalization of the execution, an investigation from various aspects such as the scenery design, material selection, pursuit of new structure and so forth will become necessary. In a main meeting, 15 volumes of paper on the most advanced technologies of PC cable-stayed bridges were presented. The presentations from Japan were 11 volumes, and occupied about 70%, and therefore a high interest to the PC cable-stayed bridges in Japan was inferred. In the presentation from Japan, there were many relevancies of the important study themes which would become a foundation for a development of PC cable-stayed bridges in the future, like ones that an improvement effect of dynamic behavior such as the aseismatic property, wind endurance and so forth was made as an objective, ones that a safety evaluation at an ultimate state as the oblique member anchoring part, main tower or entire structure was related, ones that a construction of the various control systems when the cable-stayed bridges were executed was concerned and so forth. 23 figs., 1 tab.

    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.

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

    A thin film single crystal silicon solar cell module is developed, in which a porous silicon layer is formed on the surface of a long-sized single crystal silicon substrate, a single crystal silicon film is integrated on the layer by epitaxially growing the film thereon to form a solar cell, and the solar cell is peeled off from the silicon substrate and transferred to a plastic film substrate. The achievements during this fiscal year may be summarized as follows: simultaneous formation of a porous silicon layer on a silicon substrate, reduction of anode formation current density from 200 mA/cm{sup 2} to 10 mA/cm{sup 2}, development of a silicon epitaxial device using a carbon heater, and attainment of aperture conversion efficiency of 11.8% in a thin film single crystal silicon solar cell. Three kinds of methods were developed to peel off the solar cell. A method was developed to grind silicon substrate surface from which the solar cell has been peeled off. A technology was developed to obtain a long-sized silicon substrate of about 30 cm times 10 cm times 0.1 cm from a 4-inch silicon ingot by using a wire saw. (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).

    The paper described the fiscal 1997 results of the study of the condensation base precise structure control conducted as a technical development of materials to heighten efficiency of power generation facilities. Condensation base polymer is an important material which occupies most of the engineering plastics. The study is aimed at developing basic technologies on the molecular weight and regularity by which a remarkable improvement can be expected in performance of condensation polymerization/ring-opening polymerization polymer materials, polymerization catalyst which arbitarily controls the primary structure such as branch and end group structures, and development of the precision polymerization process. In the synthesis of ordered polymer by direct polycondensation, synthesis of ordered polyamide from asymmetric monomers is studied. In the synthesis of chemically selective polyamide by direct polymerization, polyamide with functional group is synthesized by polymerizing without protecting functional group the monomer with such functional group as causes side reaction in polymerization. In the synthesis of polyamide having the limited distribution of molecular weight, the molecular weight/distribution of polyamide are controlled by connectedly conducting polycondensation which is itself to be done successively. 91 refs., 72 figs., 43 tabs.

    Described herein are the FY 1996 results of development of fabrication technologies for high-quality CuInSe{sub 2}-based photovoltaic cells. The Cu-Ga alloy/In-stacked precursor film is prepared for production of the high-quality thin-film absorber applicable to large-area module fabrication, and selenized by the vapor-phase selenization in a H{sub 2}Se gas atmosphere to produce the thin light-absorbing film in which In and Ga are present at graded concentrations. Increasing Ga alloy content in the CIGS-based thin-film photovoltaic cell fails to widen the forbidden band and improve V{sub oc}, and further optimization works are needed. The method is developed for production of thin-film buffer layer of sulfur-containing Zn compound which can give the cell characteristics equivalent to those of CdS generally used for CIS-based thin-film photovoltaic cell. It is clarified that the photovoltaic cell characteristics can be improved by use of a transparent electroconductive ZnO film of stacked structure, produced by a combination of RF sputtering and DC sputtering. For the patterning technologies necessary for forming series connection on a mini-module, the laser scribing method is applicable to the metal base-electrode, and the mechanical scribing method to the light absorber and window layer.

    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. As the result, a conversion efficiency of 11.0% was achieved. In a cost estimation for large-area CdTe solar cell modules, 140 yen/Wp (conversion efficiency: 11.0%, annual production: 100 MW) was obtained. (NEDO)

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

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

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a machine tool field. Corresponding to construction of an environment-friendly recycling economic society and economic growth as estimated change in social and industrial structure during 2010-2025, major themes are reuse of machine tools, energy saving, environment design, chip treatment and resource recovery. With preparation of information infrastructures in an advanced information society, major issues are 3D-CAD, remote diagnosis, remote control and self-restoration. Because of decline of the birth rate, positive employment of aged persons and women is desirable. New machining technology for new materials, and fusion of various machining technologies are important. For micro-technology, study should be made on the concept and effect of micro-factory (energy saving, space saving, cost reduction, higher accuracy and higher speed). For higher-accuracy machine tool, static, dynamic, thermal and movement characteristics are the key for improving the proper technology. For faster machining. fine basic structural element, faster main spindle and faster feed are important. (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.

    This R and D are aimed at establishing technology to support the reservoir modeling work required for predicting the reservoir variation from the geological/geochemical side. The contents of the development are (1) establishment of the practical measuring system for core fracture system, and (2) establishment of new modeling support technology. In (1), as the core fraction system measuring system, the measurement of fluid inclusion homogenization temperature and melting point and laser Raman spectroscopy were applied to the Wasabizawa area to obtain the results. In (2), the R and D were conducted of a rapid age measuring method for altered rock/unaltered rock and an analytical method for fluid flow using trace chemical components of hydrothermal minerals. In the former, 3-D thermoluminescent intensity of the age-known quartz was measured. The TL age of weak altered rock of Kijiyama dacite in the Wasabizawa area was 320Ka, almost the same result as 320Ka already reported. In the latter, trace components of quartz were measured at each well, and changes in the depth direction were made clear. It was made clear that the variation of Na/K ratio is large around the lost circulation stratum. The geothermal fluid flow was made clear by the analysis of similarity of the intensity ratio. (NEDO)

    This paper reports the study results on the fabrication technology of over-layered TCO on tempered glass in fiscal 1994. (1) On the fabrication technology of heat-resistant over-layered TCO, thermal deformation of TCO substrates was studied by both experiment and numerical computation. The thermal deformation increased with carrier concentration. As the observation result on change in lattice strain of heated TCO films by high-temperature X-ray diffraction, lattice strain was largely affected by thermal expansion. (2) On development of the low-temperature heat treatment method of TCO films, a technological prospect was obtained for fabrication of low-resistance TCO films by heat treatment without strength deterioration of tempered TCO substrates. (3) On development of cost reduction technology, the large-area CVD equipment was devised on the basis of the inline tempering method which tempers substrate glass by air cooling after formation of SnO2 film as fabrication method of tempered TCO. The TCO substrate tempered by air cooling could endure the drop test of 227g and 1.5m. 5 figs., 1 tab.

    In connection with the innovative manufacturing of large base materials having a mesoscopic grain structure by means of technologies for high deformation accumulation control, recovery/recrystallization control, etc., research was conducted on evaluation technology for various characteristics such as formability, with fiscal 2000 results compiled. For the purpose of evaluating average grain size from an optical microscopic photograph of structures, it was judged reasonable to determine the average cut piece length. A device introduced to this development project was a horizontal goniometer capable of ODF (crystallite orientation distribution function)/pole figure measurement, qualitative analysis, and residual stress measurement. With warm rolling performed by controlling both material temperature of 7475 based alloys and roll temperature, thermally stable micro sub-grain structures were obtained. As a result of ODF analysis of this warm-rolled material, it was found that a {beta} orientation group existed very sharply in the area from the sheet surface to the center planar part of the thickness. The grain refinement of 5083 based alloys using a warm rolling method was also successful, with its ODF analysis revealing that the accumulation of the {beta} orientation group was very high as in the 7475 based warm-rolled materials.

For the production of petroleum substituting useful resource, conditions were established of callus induction from immature embryos of tropical oil crops, especially oil palm, and of regeneration of a lot of small plants from the callus. To establish the Agrobacterium-mediated transformation system of oil palm, the binary vector harboring the reporter gene and selectable marker gene was constructed. Using the vector, oil palm tissues are inoculated and infected with agrobacteria. To heighten the function of palm oil, 10 particular clones were selected from the complementary DNA library obtained from oil palm fruit tissues. The genetic study of germs was also made. (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.

    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.

    Development of information communications technologies that surpass the global communications network is being pushed forward in order to establish the global village that McLuhan foretold in 1964. Effects of hybrid intensification with the intensification of communications technologies and computer technologies have become evident as facsimiles, automated teller machines of banks, home videos, automatic response telephones with synthetic voices, compact disks, portable telephones, video games and high-definition televisions were developed and put to use in a wide range. Intensification and integration of computer technologies and communications technologies has every possibility, but it also has a peculiar aspect of lacking guiding principles. Uncertain factors of the values of informations in the market are ever increasing, and their true values are yet to be found. Anyhow, it is a long way to the goal of the global village.

    This paper explains technical issues and a prospect for intelligent computer assisted instruction (ICAI) which combines the intelligent tutoring system (ITS) with an open-ended (discovery) type education system. The paper summarizes the ITS characterized by modelling students based on error-origin diagnostic technologies; various functions that have been realized for the first time therefrom; different methods for error diagnosis and error-origin diagnosis; and criteria to evaluate these methods (evaluating generality, coverage, and tractability). The paper indicates that no complete diagnostic methods have been obtained according to these criteria, that, therefore, an issue of incompleteness in the student model still remains, and that unsolved issues in the ITS include some that exceed the framework of the ITS. Also mentioned in the paper are that the discovery type education system has a possibility of realizing an education with new quality, and that a new attempt is being performed to merge the ITS with the discovery type education system. 17 refs., 2 figs.

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

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

    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.

    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 progress of bridge erection technology. It introduces the results of cable erection, rotated/extruded erection, and cantilever erection. The cable erection is a multi point suspension erection using cables. For the rotated/extruded erection, the monolithic construction is conducted on a working yard set in a right angle to the construction position, and the horizontal beams of the bridge piers (corbel girders) are constructed by the rotated method using a slewing base incorporated around the bridge piers at one side. For the construction of stiffening girders of Innoshima-ohashi Bridge of Honshu-Shikoku Joint Bridge in 1978, trussed face bar blocks were extruded from the main tower in order using a travel crane. For the suspension bridges and cable stayed bridges, main towers were erected using various types of cranes. The erection of Tamashima-ohashi Bridge with a weight of 500 ton using an offshore floating crane is introduced as a large block method. Analysis methods and measurement techniques at the site are used in order to analyze the shape in each step under the erection and to ensure the accurate final complete shape. Reduction of the construction cost, improvement of erection technology, and technology development for large-scale projects are subjects in the future. 22 refs., 8 figs., 1 tab.

    As to high performance/high function plastic materials used in power generation facilities, technical trends were surveyed on the recycle situation and recycle R and D to study the subjects to be solved. For wire covering materials, vinyl chloride, polyethylene, rubber, etc. are used, and the recycle of resin has not been advanced. Concerning the generation of waste plastic, the existence of a lot of plastics different in characteristics makes the recycle difficult. As to the use of waste plastic as resource, the material recycle and recovery of combustion energy are being made, but only a part of the plastic is reused as chemical raw materials. Relating to the R and D of the chemical recycle technology, there are sample studies on the pyrolysis of polyolefine, dechlorination of chlorine base resins, etc. Recently, the following have been made public: proposal of depolymerization monomer based on the cyclic monomer, study of liquefaction of approximately 100% of the thermosetting resin, approach to the solvolysis by supercritical solvent.

    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)

    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)

    A survey is conducted of wet-type solar cells that may constitute an important field in solar chemistry. The wet type solar cell made known by Graetzel et al. in 1991 is a combination of ultrafine TiO{sub 2} grains and a sensitizing dye. The ultrafine grain surface structure enlarges the area of an electrode for the absorption of 46% of incident solar radiation of which 80% or more is converted into electric power. The fill factor at 520nm of a cell fabricated for an additional test turns out to be 40% against the 76% mentioned in technical literature, and the conversion efficiency 10%. The Titanyl sulfate is also tested because it is low in price as material for titanium oxide. Functional groups are experimentally introduced for the generation of bonds on the substrate to be effective in the injection of a sensitizing dye. A sensitizing dye with two carboxyl groups and two bipyridine rings as ligand is allowed to be supported by TiO{sub 2}. IR (infrared) spectrometry is performed, and then formation is found of ester-like bonds or chelate bonds due to the interaction of carboxyl groups and the substrate surface. This is enhanced by surface treatment. (NEDO)

    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 realization of urban society respecting enhanced energy efficiency and environmental protection, cities and surrounding industrial facilities are investigated for the development of element technologies involving energy recovery, conversion, transportation, storage, delivery, utilization, etc., and for the compounding of urban energy systems. In the study of the effect of introduction, assumption is made of delivery of heat to an urban heat accumulation district from a plant equivalent to a district air-conditioning system which is covered by the existing technologies. Also assumed are the delivery of exhaust heat to the said plant utilizing eco-energy element technologies and the replacement of existing technologies by eco-energy element technologies. Comparison is established in terms of energy efficiency, environmental protection, and economy, and then it is found that the eco-energy element technologies for the utilization of exhaust heat are in all cases superior to the conventional technologies as far as energy efficiency and environmental protection are concerned. It is found, however, that they are inferior from the economic viewpoint. The energy efficiency technology in heat transportation is superior to the existing technology in energy efficiency and environmental protection but roughly equal to the existing ones in economy.

    Enzymatic and chemical methods were combined and methods were developed for synthesizing mucin type sugar chains and glycopeptides. The influence of sugar chain positions and structures on glycoconjugate stereo structures and physiological activities was analyzed, and glycopeptide structural activities and glycoconjugate remodelling were studied. To create an industrial advantage in a glycoprotein production system by use of zooblasts, sugar chain structure control through sugar transfase occurrence control was studied. For the production of man-adaptive sugar chains using yeast, new yeast variations were subjected to molecular breeding, and tested for the resultant improvement on productivity. Sugar chain marking and refining techniques and various responding mechanisms on the solid surface were elucidated, which enabled structure analyses using sugar chain recognition molecules such as lectins and antibodies. A database on interactions between sugar chains and sugar chain recognition molecules was constructed using the said findings. An analyzing program was also formulated tentatively.

    The aim is to manufacture the above at low cost by a dissolution/deposition method. Under this method, a film is fabricated containing crystals high in quality and large in size though the film area is very small. In fiscal 1998, an effort to fabricate a film to cover a 10cm square substrate failed. The failure is explained by that the heater was too small for the substrate area and that the failure to uniformly heat the substrate resulted in an inplane temperature distribution greater than expected. The furnace was modified in a minor way to narrow substrate temperature distribution as much as possible. Another attempt was made to fabricate a larger-area film on a 5cm square substrate, and then crystals grew to cover approximately the whole surface of the 5cm square substrate. Efforts will continue to achieve the goal. As for the mechanism of film fabrication on substrates of different kinds, self-coating is now described by difference in heat conductivity between a carbon substrate and silicon substrate. Thanks to individual control in a small film fabricating unit, a film thickness of approximately 100 micrometers was achieved. The distance of diffusion was 30 micrometers or more in the case of a small area, and the efficiency of a solar cell using this film was found at 10.2%. (NEDO)

    Research and development was performed by noticing on the plasma spraying method as a process that can manufacture thin poly-crystalline silicon films at a high speed. Fiscal 1997 has established a technology that can form a silicon film directly without using seed crystals in an area of 2-cm square on a carbon supported substrate by using a small film manufacturing equipment using the dissolution and deposition process. The size of the crystal is as very large as several hundred {mu}m, by which a possibility of making high-performance solar cells was verified. Discussions were given to apply this technology to large-area substrates, whereas a device was developed, which is capable of forming a film in an area corresponding to 10-cm square. According to a film forming experiment using this device, the film has begun being formed on part of a 10-cm square substrate, verifying the effectiveness of this method. While the film thickness is about 100 {mu}m, it was confirmed that the crystal size will not change even if the thickness is made mechanically as thin as about 50 {mu}m. Further discussions were given on enhancement of wettability by means of coating, and light enclosing structure. (NEDO)

    This paper explains the principles of microwave power transmission as a long-distance power transmission technology, and the status of its development. Under an assumption of using a wave length of 12 cm (2.45 GHz) and a transmission distance of 1 km, an ideal wireless power transmission can realize transmitting the power at an efficiency of 95% or higher if transmitting and receiving antennas with a radius of 8.8 m are used. What remains as important requirements is raising the efficiency of conversion from power supply into microwaves, and the efficiency of rectification after the power has been received. By using microwave energy sent from a transmission antenna installed on the roof of an automobile, a model airplane with a receiving antenna installed at its rear flew successfully for 40 seconds under the microwave lifted airplane experiment (MILAX). In an experiment of transmitting microwave power in space, power was successfully transmitted to the child rocket as an event under the International Space Year - Microwave Energy Transmission in Space (ISY-METS). The microwave wireless power transmission on the ground would have a possibility of taking over the overhead line transmission into islands. An attempt is scheduled to send power of 5 kW by using transmission and receiving antennas with a diameter of 3 m to investigate effects on transmission efficiency, and communications and electromagnetic environments, and to collect basic data. 3 refs., 3 figs.

    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.

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

    A newly developed magnetic sensor for non-destructive inspection has acquired the U.S. patent. The starting point of the invention was an inspection of aluminum broth bags in cup-noodle containers with aluminum leaf cover, which was asked from a food maker. A method was developed, in which the microwave is transmitted through containers below their covers and the reflected wave is detected. Then, development of an inspection apparatus for spot welding parts used for automobiles was requested. Since welding is carried out using large current for the spot welding, magnetic characteristics change greatly, which is a remarkable phenomenon appearing especially for magnetic substances. This was found out to be the same phenomenon as the hardening of swords consisting of high temperature heating, pressurizing, and quenching. This substance with two changes can be considered as another material different from the base metal. Coils fitted to impressions were made, and their test pieces were measured. The correlation coefficient over 0.9 was obtained between measured values and results of tensile strength tests. This apparatus can be applied to the non-destructive inspection of internal defects of castings. 2 figs.

    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.

    The recent circumstances domestic and abroads around `environment` are showing a kaleidoscopic movement with the Earth Summit in 1993 as a turning point, such as the materialization of the Environmental Fundamental Law, enactment of environmental policy fundamental principle by the Ministry of Construction, and furthermore and adoption of the earth environmental action plan-agenda 21-by the Japan Society of Civil Engineers. Under the circumstances like this the civil work execution study committee has planned this panel discussion for study, for a purpose of catching hold of the environmental problem from a standpoint of the actual constructor and furthermore searching for what should be done. As a consequence, the various opinions have been presented as follows: Namely, in order to grapple with the environmental problems it is required for that a co-operation work of the civil engineers should be done with the people in the other field. As for the environmental problems, a discussion forecasted for the future is necessary. Because an environment itself is fuzzy matter, it would be better not to give the too clear solution for a concept. An attitude to make much of the matter which can not be counted is needed. The mitigation (influence alleviation countermeasure) is required for applying flexibly.

    In order to increase the geothermal power generation volume in Japan furthermore after now, it is necessary to develop the deep-seated geothermal fluid collecting technique at 3,000 to 4,000m in depth and about 350degC. In order to collect the deep-seated geothermal resources economically and effectively, there are some principally important problems on production techniques such as P (pressure)-T(temperature)-S (flow rate)-D (fluid density) logging technique, P (pressure)-T (temperature)-C (chemical composition) monitoring technique, high temperature tracer monitoring technique, scale monitoring technique, scale protection and removal technique and so on. The PTSD logging technique is a measuring technique for collecting some data necessary to conduct production management effectively. The PTC monitoring technique is a technique for collecting data on the geothermal resources essential for the resources evaluation and presumption, and tracer monitoring technique is a technique for collecting actual measurement data of fluid flow analysis in the deep-seated geothermal resources. And the sale monitoring is a technique for collecting data on various kinds of scale components of the deep-seated geothermal water and in the steam. In this paper, these techniques are summarized. 8 figs.

    Described herein are the reports presented to the industrial technology subcommittee, 17th symposium of NEDO projects. For development of high-efficiency industrial furnaces by high-temperature air combustion (including regenerative combustion), high-temperature air above 1000 degrees C is used, where carbon dioxide and NOX are possibly abated by 30% or more and 50%, respectively. The worldwide development is also described. 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 Niigata-Sendai natural gas pipeline was constructed in 1996 by Japan Petroleum Exploration Co. to transmit indigenous gas produced off Niigata Pref. and imported gas from Indonesia in the form of LNG to Tohoku Electric Power Co.`s Sendai Thermal Power Station. It is the second longest onshore pipeline in Japan extending 251km (nominal diameter: 20in.). Kawasaki Steel participated in the construction project from the preliminary investigation and planning stage, and constructed a 97km long section, which is approximately 39% of the total length. Various new techniques were applied to secure safety and reduce cost. This paper outlines the project and some of the representative techniques adopted for the project, such as field bends cold-worked on 11m long straight pipes, work management system for constructing long-distance pipelines, coordination for the test runs and verification of the designs. 3 refs., 12 figs., 5 tabs.

    Biosafety, in other words, biohazard countermeasure is to prevent biological disasters, in particular, hazards caused by microbes infecting human beings or things, and they are roughly classified into two kinds. One is a disaster of infection via pathogenic microbes originally existing in the nature or allergens and toxins which microbes produce. The other is a potential, unknown hazards in the field of so-called biotechnology such as gene recombination technology. This paper describes the features of microbe pollution and measures against biohazard. The basis of the biohazard countermeasures is isolation from microbe pollution, and in reality confinement of microbes. As to methods for confining microbes, in addition to physical confinement, there is a biological confinement method using a host-vector system which is hard to exist in conditions other than special incubating conditions in recombination DNA experiments. 3 refs., 3 figs., 2 tabs.

    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)

    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)

    The coal cartridge system (CCS) is a series of the total system, in which coal is processed centrally at a supply base for each unit of consumer areas, supplied as pulverized coal in bulk units, and coal ash after combustion is recovered and treated. The system is expected of advantages resulted from the centralized production, elimination of handling troubles, and cleanliness. Following a small scale demonstration test, a large demonstration test for practically usable scale has begun in 1990, and completed in fiscal 1995. This paper introduces the CCS and reports the result of the test. In the large demonstration test, a supply station (with manufacturing capability of 200,000 tons a year) was installed in the Aichi refinery of Idemitsu Kosan Co., Ltd., and systematization on quality design and system technologies has been carried out. Long-term continuous operation for five years was achieved (operation time of the supply facilities was about 19,000 hours) without a failure and accident, to which every elemental technology was evaluated highly, and convenience and reliability of the system was verified. 13 figs., 3 tabs.

    In order to utilize more effectively coal ash whose generation amount is increasing year after year, studies have been made on a technology to manufacture and utilize a high-strength substance solidified under normal temperature by utilizing hydration reaction of pozzolan system (Poz-O-Tec). The study works have been done as a subsidy operation of the Agency of Natural Resources and Energy, and were completed in fiscal 1995. Poz-O-Tec is a wet powder made of coal ash and stack gas desulfurization sludge (gypsum) added and mixed with lime and an adequate amount of water, which solidifies by hydration as pozzolan does. The same method as used for ordinary sands may be used as the basic application method. Because this is the material whose strength increases after construction, thickness of construction may be reduced smaller than in constructions using soils and sands. Test constructions of about sixty cases have been carried out to date, typically represented in use as a road bed material, banking, and a base material for water-barrier gutters. High-strength solid material which is stable under normal temperature may be obtained by adjusting calcium content. As a result of its effectiveness in practical use having been verified, a certificate of technological judgment has been issued for the material by the Civil Engineering Research Center. 3 refs., 11 figs., 2 tabs.

    For the foundation improvement works by grouting in a borehole, evaluation of grouting effect is one of the most important management items. The grouting design and works are sometimes reconsidered depending on the evaluation of grouting effect during the test injection. The purpose of the evaluation of grouting effect is to grasp the range of improvement and consolidation after the injection, and to judge and estimate the strength and permeability of the consolidation part. This paper describes the judgment method of the strength using PS logging results and borehole televiewer (BHTV) logging results. The reflection intensity (Ir) by the BHTV logging increased after the grouting, which showed a same tendency as that using S-wave and P-wave velocities (Vs and Vp) before and after the grouting. This was considered to demonstrate the grouting effect. A relation was obtained between the Vs, Vp and Ir before and after the grouting, which was expressed by following equation. Ir=0.143{times}Vs-70=0.093{times}Vp-110. The relation with the dynamic elastic coefficient (Ed) was also obtained as follow; Ir=0.0013{times}Ed. 9 figs.

    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.

    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)

    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)

    This project is aimed at surveys on the elementary and peripheral techniques necessary to construct the systems, with the objective to draw the conceptual designs of the total system for co-production of a substance and electric power. In a general reaction process, substances are produced under an advantageous condition that is dependent on reaction rate and equilibrium, where most of the energy is dissipated in the form of sensible and latent heat without being used for the chemical reaction. The co-production system under consideration uses high temperature of 500 degrees C or higher exhausted from a power station or industrial unit to produce macromolecules or synthesis gases, wherein the exothermic reaction increases temperature of the heat source, which is recovered in the form of steam for driving the steam turbine to produce electric power. On the other hand, low-temperature waste heat of around 150 degrees C is converted into a liquid fuel or other value-added products by the liquid phase pressurized system. The elementary techniques to construct these processes are surveyed, and the thermal processes are analyzed. The investigated items include substance production processes, electric power production processes and total systems. (NEDO)

    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.

    Integration of optical circuits is discussed. A number of devices used in optical communication even today treat light beams emitted by optical fibers or by semiconductor lasers as spatial beams. In making preparations for mass production in the future, the effect of mere miniaturization of optical systems on optical substrates is quite limited. Realizing the presence of such a limit is one of the motivations to endeavor to embody integrated photonic circuits. In this report, comments will be focused only on the technology of waveguide type integration. Integrated circuits on a compound semiconductor substrate are quite difficult to deal with, more difficult than generally supposed. This is a task with a bright future when reviewed from the viewpoint of the effective use of the quantum effect. If integration is to be effected on a Si substrate, possibilities are high that the effort will bear fruit now that the substrate can withstand the full application of micro-machining. An LiNbO3 wave path, however, wants a breakthrough in the switching technology. As for the material to coat substrates with, polymer based nonlinear optical materials are not satisfying. The integrated photonic circuit technology can be said to be on the stage where questions limitlessly surface also in the science of materials. 14 refs., 2 tabs.

    With an objective to prevent global warming, research and development has been made on a carbon dioxide fixation technology using electrochemical means. This paper summarizes the achievements in fiscal 2000. In the research of a technology to return carbon dioxide to hydrocarbon such as methane electrochemically utilizing the high concentration carbon dioxide-methanol system, basic studies were performed on electrolytic reduction of CO2 using a methanol solvent system, and experimental studies were executed on high-speed reduction of carbon dioxide using gas diffusion electrodes. In the basic property experiment on diamond electrodes, high carbon dioxide reduction activity was obtained by having copper carried in the diamond electrode. In the CO2 electrolytic reduction experiment on three-phase interface using a copper net electrode, CO, ethylene, and methane were produced, while the electrode has retained the activity for an extended period of time, and the CO2 conversion rate reached about 66%. In structuring an electrochemical carbon dioxide fixation system, specifications for the CO2 electrolytic reduction equipment were determined, design, manufacturing, and electrode materials were selected, supporting electrolytes were discussed, and the entire system flow and liquid resistance were discussed.

    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.

    For the reservoir evaluation at an initial developmental stage and stabilization/maintenance of power after the start of operation, the fiscal 1997 result was described of the study of technology of prediction of reservoir variation. Using the conventional post processor, feasibilities were computed of reservoir models and behavior after the development, and gravity/self potential/resistivity variation. Variation in the seismic wave speed structure was large in travel time change distribution. The measuring accuracy of 1m sec is required to get enough detection resolving power. A conceptual design of the post processor development was conducted to study a system operated on Windows. Based on the reservoir numerical simulation technology, by taking in variation parameters such as gravity and self potentials as new model constraint conditions, the reservoir modeling technology which increased in accuracy by history matching was trially developed. Using the conventional reservoir model in the Oguni area, predictably computed were reservoir behaviors during 50 years which simulated a 20 MW development. Effectiveness of the post processor were able to be shown though influenced by characteristics such as permeability and resistivity. 74 refs., 95 refs., 12 tabs.

    Surveyed are the roles of the government, important for environmental buildup for technological innovation. The U.S. research and development support programs are classed into contracts, grants, cooperative agreements, and CRADAs (Cooperative Research and Development Agreements). The government financially supports the first three, but not CRADA. It provides CRADA with manpower, facilities, and resources. The research and development (R-and-D) appropriation not for national defense in the U.S. fiscal 2000 budget is up 36% to $39.4 billion occupying 50.6% of the total R-and-D expense. The basic research appropriation is given the highest priority, enjoying an increase of 4.7% to $18.1 billion. In the U.S., taxation for R-and-D expenses is done in two ways. One is a research expense tax deduction system under which R-and-D expense is handled as a cost, a subject of deduction. The other is a research and experiment tax deduction system under which a certain percentage of R-and-D increment is free of taxation. NEDO's (New Energy and Industrial Technology Development Organization) system for national R-and-D projects is scheduled to change extensively upon reorganization of the government ministries and agencies in January, 2001.

    Tandem type solar cells are developed, in which solar cells with different band gaps are stacked for effectively utilizing optical energy across the entire range of solar spectrum. A material gas supply control device for multiple epitaxial growth was added to a large-area GaAs film epitaxial growth unit, and a film thickness homogeneity of {+-}1% was achieved. A GaInP epitaxial layer fabricated in the same way was also enhanced in homogeneity. A low-carrier concentration layer was inserted into the top cell GaInP p-n junction for the construction of a p-i-n structure, and this improved on the short-circuit current. Furthermore, a p-p-i-n structure was constructed having two emitter layers, and this improved on spectral sensitivity for the achievement of a conversion efficiency of 13.6%. Studies were conducted about the tunnel junction which plays an important role in the stacking of cells, and the tunnel peak current was increased to 7.41A/cm{sup 2}. Fabrication is now under way of a GaInP/GaAs stacked cell, which is expected to exhibit a conversion efficiency of 25% or higher. In the case of a GaInAs cell to serve as the bottom cell, a conversion efficiency of 5.1% was achieved. Consequently, it is safely expected that a 3-junction stack of GaInP/GaAs//GaInAs will exhibit a conversion efficiency of 30% or higher. (NEDO)

    This technological development is intended to develop a process technology to dispose adequately of air bags convergently when they are removed from waste cars, with consideration paid on environmental and safety aspects. This technology that can dispose of air bags remaining as air bag modules (ABM) in large quantity and adequately can solve the problems of maloperation in opening them in cars and noise in conventional disposal methods. The recovery and disposal system using an inflator can be expected of reducing work load on dismantling contractors and enhancing the work safety. Furthermore, the energy saving process utilizing combustion of plastics can save resources. However, this technology has not elucidated how dioxins, dust, smoke, sulfides, and nitrogen oxides are generated and how the generation can be prevented. Therefore, an exhaust gas dioxin testing facility and an exhaust gas treating facility were installed additionally to the existing heating treatment facility to develop a disposal technology to treat adequately the exhaust gases generated when ABMs are disposed conveergently in large quantity, and treat the waste water discharged from the facilities. Fiscal 1998 has performed preliminary tests to accumulate fundamental data, and design and installation of the above two facilities. (NEDO)

    With an objective to improve the environment by substituting petroleum energy by coal, and by reducing emission of SOx and NOx, research and development has been performed on coal liquefaction technologies. This paper summarizes the achievements thereof in fiscal 1999. In the disassembling study, wear, corrosion, and wall thickness change were investigated, and non-destructive inspection was performed on the major four facilities, and such newly developed devices as the liquefying catalyst manufacturing facilities, the slurry heat exchanger, and the let-down valves. The sampled test pieces were investigated of changes in the mechanical properties by means of the metallic structure inspection, hardness test, tensile test, and impact test. Deposits in the devices were investigated of their depositing conditions and constituents. The result reveals that the 3 Cr-1Mo-1/4V-Ti-B steel developed for the high-temperature, high-pressure, and hydrogen environment of the coal liquefaction plant showed excellent low-temperature tenacity and maintained good characteristics. No problems were discovered in corrosion resistance if PP using materials are used. The slurry handling centrifugal pump and instrumentation vales were worn out severely requiring replacements during the operation, for which further discussions are desired to be given. (NEDO)

It is a lighting power source installed in fiscal 1994 on the third-floor rooftop of the management information building of Kanagawa Prefectural Industrial Technology Research Institute. It has a capacity of 25kW, operating on system interconnection (no back flow), and has a single 15-series/26-parallel array (mono-crystal modules) facing 38deg westward from due south and inclined at an elevation angle of 20deg. From the 240000kWh insolation that contributed to power generation, a DC power output of 28000kWh was obtained, output of 25000kWh after conversion into AC. The module efficiency was 10.8-13.8%, higher when the daily mean temperature was lower. In the case of 3kW type expected to diffuse into the residential and commercial sector and household sector, one will output 3000kWh a year, which is an appropriate capacity as a locally distributed type power generating system in view of the monthly consumption of 2000kWh by a household in general in the Tokyo Electric Power Co., Ltd. service area. No problem is found in reliability of the tested system. Although the power it generates is less than what this office consumes, it is effective in enlightening people about resources saving and peak cut in summer

    The paper described the results of the development of technology of low temperature materials in the fiscal 1997 WE-NET. Using experimental equipment for materials under the atmosphere of liquid hydrogen, an experiment on mechanical characteristics under the liquid hydrogen atmosphere (20K) was conducted of the base materials of candidate steels (SUS304L, SUS316L and A5083). In material evaluation experiments (tension/fracture toughness/fracture tests), characteristic behaviors of the materials were shown which are different from those shown in the environment of liquid He (4k), etc. Even if the amount of {delta} ferrite in the metal welded of the stainless steel is small, approximately 1%, the degradation of low temperature toughness occurred. Welded joints of stainless steel by submerged arc welding and MAG welding were in now way inferior in tension characteristic to those by TIG welding, but were inferior in toughness ranging from room temperature to extremely low temperature. As to aluminum alloys, materials excellent in extremely-low temperature toughness were able to be found. Under the low temperature hydrogen gas atmosphere, the lower the strain rate is, the higher the hydrogen brittleness susceptibility is around 220K (extremely large hydrogen brittleness temperature) (SUS304L). In the hydrogen gas of 100 atm, hydrogen invades the material at 100degC, but does not at 77k. 38 refs., 173 figs., 48 tabs.

    A high-density information network society is going to be realized in the 21st century. Information communication devices used therein are demanded of having high speed and high performance including acoustic and image digital processing, reduced size and weight, and low electric power consumption. While explosion in increase is estimated in the quantity of information handled by these information communication devices, there is a trend that the speed increase in CPU cannot follow the quantity increase. The present proposal is intended to make drastic performance enhancement by using the electron SI (comprehensive mounting) technology which includes making the LSI chips three dimensional and compounding light and electric power mounting, as well as design optimization. The present research and development has an objective to integrate the following three elements to achieve an ultra-high density electron SI technology: (1) a three-dimensional lamination technology making shortest wiring between LSI chips possible, (2) a light and electric power compounded mounting technology making high speed and large capacity transmission inside a board possible, and (3) optimal wiring structure design to suppress unnecessary electromagnetic radiation caused by increasing signal speeds. The research plan period lasts for five years. This paper reports the progresses in each theme in fiscal 1999. (NEDO)

    This paper describes the surveys in fiscal 1999 on establishing industrial technology strategies in the human life engineering field. The human life engineering is an engineering to identify scientifically humans and their living characteristics, and apply them to products, systems, and environment building. Market size for the human living related industries is more than two trillion yen, whose annual growth rate is 9%. Discussions were given on problems that hinder technological innovations in this field. What lacks is the comprehensive strategic conception, and insufficient is the structural approach by related organizations. Technological systems for designing have not been established, and technological foundations relative to human characteristics and living characteristics are not well arranged. Methods to evaluate research achievements have not been established, and the works on proposing international standards are weak. Insufficiency in human resource nurturing is also an issue. As the future prospect and strategies, such fields as psychology, recognition, and sensitivity are important for the seeds technologies, and so are the measurement of supportive technologies, and information processing. The human living engineering aims at supporting safety, freedom from care, and high-quality life, realizing industrial and technological competitiveness of the world top groups, and forming societies with activity and high quality.

    During ultrafine structure formation due to transformation from austenite to ferrite in an intense magnetic field, the transformation is accelerated by the thermodynamic stabilization of the ferrite phase which is ferromagnetic. The application of an intense magnetic field works effectively during the generation of nuclei. When a magnetic field is applied during reverse transformation, a honeycomb 2-phase structure is formed oriented toward the direction of the magnetic field and, when the structure is vertically compressed, the recrystallized structure is made ultrafine effectively. In pearlite transformation, hardening occurs when carbon atoms supersaturated in density are introduced in the presence of a magnetic field gradient, and curing further promotes precipitation hardening. In a ferrite complex phase system, wherein ultrafine globular cementite is uniformly distributed, plastic instability becomes explicit in a tensile test. There is a good possibility that an ultrafine structure recrystallization model may be built by calculation, into which the distribution of energy stored prior to recrystallizing nucleus formation is incorporated. The profile of a conceptual process of off-line or in-line integration of heavy-strain process and intense magnetic field application has become tangible. (NEDO)

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

    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.

    The paper made a research survey of a technology to decompose the recovered CFC (specified freon) in which energy efficiency is high and no hazardous materials such as dioxin are generated. As to the technology to decompose specified freon, the high frequency plasma method, the cement kiln method and the combustion method are at the stage of the demonstration test and close to the commercialization. The catalyst method has finished the basic test and is at the stage of a pilot plant. Besides, there are the supercritical water decomposition method, the ultraviolet decomposition method, etc., but they are at the stage of the fundamental research. Mechanisms of the dioxin generation and the suppression of dioxin generation in case of incinerating waste mixed with halide have been made clear. In the fundamental test, conditions were obtained under which the freon decomposition rate of more than 99.99% is attained by the combustion of a mixture of industrial waste and freon using the combustion method, and measures for reduction in hazardous materials such as dioxin were expected to be taken. In the catalyst method, the result obtained was the decomposition rate of more than 99.99% and the catalyst life of more than 1000 years, and its practicality was confirmed. 43 refs., 97 figs., 29 tabs.

    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.

    This paper introduces the following technologies and countermeasures found to be successful in solving geochemical problems relating to the maintenance and management of geothermal power plants belonging to Kyushu Electric Power Co., Ltd. In controlling condensate properties,curtailment of pH fluctuation range by changing the injection point of NaOH,inactivation of sulphur bacteria by using chloramphenicol and prevention of slime loading of the condenser strainer by running of the cooling tower without make-up water were achieved. In the environmental countermeasures,it was concluded that Fe-ion injection method was most effective to remove As out of waste hot waters which are all reinjected into the underground formation now. By understanding the characteristics of the well eruption fluids,the attenuation mechanism of steam producing wells could be estimated, which were interference,re-eruption and degradation of the reservoir temperature caused by the reinjected hot waters. And the problems associated with the attenuation of steam producing wells have been solved fundamentally by taking proper countermeasures to eliminate the influence of reinjected hot waters. The atteunuation of reinjection well was found to be caused dominantly by silica loading at the permeable zone of wellbore and to be effectively solved by high temperature reinjection of the waste hot waters, controlling of temp. degradation of hot waters to be reinjected and prevention of air mixing. After applying proper countermeasures, the attunuation rate of the reinjection well has been fairly improved. 13 refs., 21 figs., 2 tabs.

    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.

    In utilizing coal for high-efficiency direct power generation using fuel cells, it is necessary that coal be fed into the fuel cells after having been made into ash-free gaseous fuel. Research and development works are being carried out with an objective to develop a coal gasification furnace most suitable for fuel cells and establish a system to refine coal up to the one that can be fed into fuel cells.

    High temperature and high pressure steam has been investigated for the high efficiency waste power generation technology development. The steam temperature below 300 centigrade is currently employed to avoid the corrosion of superheater, and the generating efficiency is less than 15%. Practical application of 500 centigrade and 100 kg/cm{sup 2} is planned by developing corrosion resistance materials. Environmental load reduction technology has been also developed. For the external circulation type fluidized bed furnace combustion tests using dummy waste in fiscal 1995, the temperature control at bag filter was effective for suppressing the dioxins. When using waste plastics, HCl could be reduced by blowing Ca compounds. Various Cr-Ni-Mo-based alloys have been developed as a corrosion resistance superheater tube material, and are currently tested. For the environmental load reduction technology, the development of pulse plasma exhaust gas treatment method has been continued from fiscal 1993. In fiscal 1995, this method was confirmed using a small-scale test unit, and also tested using a 5000 Nm{sup 3}/h bench-scale unit. The removal rates of dioxins at the outlet of bag filter were 99.8% and 99.3%, respectively. They were found to be affected greatly by the pulse waveform. 13 refs., 107 figs., 24 tabs.

    Although the PHARE (Poland and Hungary Assistance for Restructuring of Economy) program which was started in December 1989 was initially intended to work for Poland and Hungary, yet the number of countries to enjoy the assistance has increased due to political changes in progress in CEE (Central and Eastern Europe) countries, and now 11 countries are under cover of the program. PHARE assistance funds are not loans, but are granted to the receiving countries as subsidies for their economic renovation activities. The funds are not invested directly in business activities, but are utilized to help governments implement their renovation programs. That is, they are spent for investigations for various renovation programs, policy and program formulation, transfer of professional knowledge and technology, and for technical assistance for education and training. The TACIS (Technical Assistance CIS) program which was started in July 1991 is again for technical assistance like PHARE, and aims to help NIS (New Independent State) countries implement their projects for transition to the market economy. Assistance activities include counselling about policy formulation, system and legal framework building, and training of experts and the supply of equipment required for carrying out the said assistance activities.

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

    With an objective of decreasing silicon usage quantity for the purpose of reducing the solar cell production cost, development is being performed on an ingot cutting technology to cut a silicon ingot to Kerf loss of 150 {mu} m and thickness of 150 {mu} m, and in which the produced wafers can withstand the cell making. Investigations revealed that a wire saw is suitable as the cutting system, and the wire used must have a diameter of less than 120 {mu} m, and a strength of more than 3850 N/mm{sup 2}. A prototype wire was fabricated, whose diameter is 120 {mu} m, and in which the strength is distributed between 3870 and 4110 N/mm{sup 2}. It was found possible that a wire of 160 {mu} m can be used to slice an ingot having a cross section surface of 150 mm square and a length of 300 mm into a slice having a Kerf loss of 200 {mu} m and a thickness of 180 {mu} m. This wafer had the in-plane distribution of the substrate thickness at {+-} 12.5 {mu}, swell of 120 {mu} at maximum, and surface roughness of 5 {mu}. Making ten of these wafers into a cell resulted in a yield of 60%. Assignments are the clarification of the properties of the cutting wire, the preparation of a thin wire with homogeneous quality, and the establishment of a technology to cut Kerf loss of 150 {mu} and substrate thickness of 150 {mu}.

    The solar energy utilizing technologies having been developed under the Sunshine Project were used to have executed the international joint technology development on the 'solar heat utilizing drying system' in the Republic of Indonesia. This paper summarizes the achievements in fiscal 1998. In operating the pilot plant, three operational experiments out of seven experiments were carried out only by Indonesian engineers. As a result of the drying experiments, the heat collecting characteristics of the collector were as about half at 19 to 30% as the efficiency assumed in the design of 50%. The reason for this can be attributed to the fact that the cover glass used in the demonstration test in Japan had light permeability of about 87%, but the cover glass used in the test plant was made of frosted glass whose light permeability was about 37%. This glass is the only glass available for a heat collector in the solar heat hot water device in Indonesia, but is unsuitable for the heat collector. Another cause was that the insolation at the site was lower by about 30% than the one used at the design stage. (NEDO)

    A technology is developed to perform high-efficiency power generation by generating high-temperature and high-pressure steam stably by burning general wastes and combustible industrial wastes as fuel. This paper describes summary of the achievements in fiscal 1998. Corrosion tests were performed on over-heater materials under steam condition of 500 degrees C and 100 kg/cm{sup 2} by using a hot model. It was verified by the tests that the corrosion environment around an external heat exchanger is milder than that with an external stack. A circulation fluid bed was simulated from operation data, and a prospect was obtained on steam conditions required for the high-efficiency power generation. In order to elucidate the corrosion mechanism, discussions were given on deposited ash properties, corrosion characteristics and stress. Elucidation was made on a discharge chamber structure most suitable for removing dioxins and NOx by using a waste gas treatment process that uses plasma generated by discharge. A concept design was made. The economic effect of the system is equivalent to that of the activated carbon blow-in process, whereas a waste gas treatment system was nearly completed. As a result of the pilot plant test, the power generation efficiency is estimated to be 30% in a scale of 1200 tons per 24 hours. A demonstration test revealed that dioxin emission was far below the regulation value. An optimal system was also discussed. (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)

    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 goal is to develop basic technologies to build an SiC device capable of service amid high-temperature surroundings for the advancement and optimization of combustion control systems. In an SiC semiconductor, the Si-C bond is broken when irradiated with ions, and this makes the occurrence of thermal oxidation easy to occur. In the study to form SiC into single-crystal substrates, a substrate with warpage of 10 micrometers or less and surface coarseness of 10 nanometers or less is realized. In the development of sensor technologies, the high-speed CVD (chemical vapor deposition) method is applied for the growth of crystals further on a 3C-SiC layer epitaxially grown by MBE (molecular beam epitaxy) surface control, which improves on layer characteristics. Element technologies are developed for the construction of a 3-terminal element (FET: field effect transistor), which is for the construction of a high-temperature, high-speed SiC device. An effort is made at achieving 3C-SiC hetero-epitaxial growth, etc., on a 3-inch Si substrate using an SiC crystal film formation experimenting apparatus, which aims at constructing a control device. Concerning the combustion control system, the relations between the air/fuel ratio and the emission spectra of radicals OH, CH, and C2 in a flame are made clear. Also referred to are the basic studies being conducted at research institutes such as universities and a survey of technological trends abroad.

    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.

    Efforts are made to develop a GaInP/GaAs-based compound semiconductor solar cell built on an Si substrate, the Si substrate being lower in cost, higher in mechanical strength, lighter in weight, and higher in heat conductivity than a GaAs or Ge substrate. Fiscal 1999 studies involved improvement on GaAs/Si heteroepitaxial growth and the evaluation of crystallinity in thus grown layers, improvement on cell characteristics, fabrication and evaluation of an n{sup +}/p structure cell, and so forth. As for crystal growing technologies, a 980 degree C 5-heat-cycle annealing method was applied, and the density of dislocation was reduced to 5 times 10{sup 6}cm{sup -2}. In the fabrication of cells, an n{sup +}/p structure cell was studied, and the cell achieved 12.5mAcm{sup -2} in short-circuit photoelectric current over 9mAcm{sup -2} of the conventional p{sup +}/n structure GaInP cell. Without any special effort to optimize the structure, a GaInP/GaAs layer-built cell on a GaAs substrate achieved 23.7% in conversion efficiency. When it is taken into consideration that conversion efficiency on an Si substrate is approximately 80% of what is achieved on a GaAs substrate, it is deemed that the achievement of 23.7% suggests that near 20% in conversion efficiency may become available on an Si substrate.

Use of common primary indexes was introduced for transitory stress, and the common primary indexes were introduced also for chronic stress. In the stress evaluation using composite physiological function measurement, data analyses were made, and discussions were given on the time series basis on the action indexes and the physiological indexes as the work performance of a work load assigning work to elucidate points of the problems. In stress indexing using skin temperatures, a possibility was obtained in indexing by using the skin temperatures on transitory stresses during tension and monotonous work. Measurement of stresses with hormone placed as the main subject tries to apply to human being the changes in hormones which have been verified since quite some time ago by animal experiments. However, it is difficult to find a definite trend because of complexity of stresses in the human society. For the basic arousal indexing, studies were made on improvement of accuracy of the monitor and quantification of actions of physical stimulation. (NEDO)

    With the purpose of obtaining higher strength/toughness in metallic materials, R and D was conducted concerning nano-sized grain refining and bulk forming by micro-grain dispersion, with fiscal 2000 results compiled. In {gamma} stainless steel, development was conducted using SUS304 as the base material, revealing that ZrC was effective for forming a micro-crystallized grain structure. In addition, it was found feasible that precipitation behavior of carbide was controllable through a temperature rising process at the time of solidification forming. In an HIP+ (hot isostatic pressing) hot forged material with ZrC finely dispersed, it characteristically showed an average crystalline grain size of about 300 nm, a tensile strength of 1,085 MPa, and a Charpy impact value of 1.86 MJ/m{sup 2}. Further, in thin plates micro-crystallized by thermo-mechanical treatment using martensite reverse transformation, a strain rate sensitivity index m value became 0.3 or higher at a strain rate of 10{sup -2}S{sup -1}, indicating manifestation of superplasticity. In {sigma} stainless steel, TiO{sub 2} and ZrO{sub 2} were examined for their effect of suppressing grain growth on the basis of SUS410. (NEDO)

    The achievements during fiscal 1993 of research and development on a method to evaluate warm heat comfort by living scenes of workers by using a human body thermal model included completion of a human thermal model introduced with physiological knowledge such as artery-vein anastomosed (AVA) blood vessels and two-system blood circulation net. The effectiveness of the model was experimented and verified. It was made possible to estimate the reversal phenomenon occurring in hot heat environment, in which skin temperatures at peripheral body parts rise higher than those in the body trunk part, and skin temperature distribution. In the correlation study to estimate statistically the sense volume from skin temperatures, it was possible to estimate significantly different sense volumes from face skin temperatures, but the estimation accuracy was low because of such factors as difference in individuals. What is important in enhancing the accuracy is to identify ecological reactions of human being caused from change in the sense volume, select effective parameters, and study the mechanisms. In order to develop stress relaxing scents, discussions were given on degree of subjectivity stress by question papers and cortisol concentration in saliva as the parameters. An experimental system was developed to measure the effects of the scents to relax work stresses. A screening method was developed, whereas effects of 15 kinds of scent materials were investigated.

    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. The R and D activities were also directed to development of techniques for creating Nb-based superhigh-temperature members, their evaluation, and imparting oxidation resistance to them. (NEDO)

    The aim is to develop a technology for detecting environmental pollution before it becomes apparent and thereby to contribute to the development of technologies to minimize the damage that may be inflicted upon the global environment. For this purpose, researches are conducted in search of techniques to detect, at high speed with high sensitivity over a wide scope, the response of living organisms to chemicals. In a research on the application of the reaction of ecosystem to environmental stress, communication between living organisms in coping with environmental chemicals is investigated. It is then found that the growth of vegetable roots may be used as a measure for the detection of environmental pollutants but that the method is too low in sensitivity. A research is conducted on the creation of an ecological reporter function using the biological amplification technique. It is then found that the immunoreaction-aided measuring of environmental pollutants yields an excellent result in terms of sensitivity but that it has a problem in its resistance to environmental conditions. In a research on the standardization of environmental measurements using ecological information, it is found that the primary object of research and development should be a systematization technology compatible with biological functions.

    Research and development have been carried out with an objective to re-utilize waste cable covering materials as oil substituting energy. The research has been performed on behavior of chlorine and lead being substances that impede making the cable covering materials into fuel, development of a technology to remove chlorine, lead and copper, and pelletizing properties for fuel making. In the study of behavior of chlorine and lead, the following matters were made clear: dechlorination reaction completes within 30 minutes if pyrolysis temperature is higher than 300 degrees C; the more the amount of filler CaCO3 in test samples, the less the dechlorination amount; and secular deterioration does not affect the dechlorination amount. A technology has been developed successfully to remove the substances that hinder making the cover materials into fuel, achieving the target values of copper at 0.2% or less, lead at 0.3% or less, and chlorine at 5% or less. In developing the pelletizing technology that puts the cover materials into raw materials for blast furnaces, dechlorination rate of 90% was achieved by mixing coke/PVC at a ratio of 1/1 and dechlorinating it by using a rotary kiln. It was verified that the product is free of problems in particle size as the blast furnace raw material. (NEDO)
