    We established a GRB follow-up observation system at the Kiso observatory (Japan) in 2001. Since prior to this the east Asian area has been a blank for a GRB follow-up observational network, this observational system is very important for studying the temporal and spectral evolution of early afterglows. We have thus been able to make quick observations of early phase optical afterglows based on HETE-2 and INTEGRAL alerts. Thanks to this quick follow-up observational system, we have so far been able to use the Kiso observatory to monitor 20 events, and conduct follow-up observations in the optical and near-infrared wavelengths

    Quantitative evaluation of physical and mental loads are effective in developing more human-friendly vehicles. Here attention has been focused on the mental load. Attempts were made to find some physiological indices that can be used for quantifying the mental load and resultant fatigue. Subjects were told to perform three different tasks in a climatoron, and the relation between physiological indices and their perception of fatigue as well as their capability of performing the tasks were analyzed. As a result, heart rate variability is a good index for quantitative evaluation of mental load and fatigue. 5 refs., 4 figs., 6 tabs.

    This paper investigates Momoyama hydraulic power station built on the middle reaches of the Kiso River in Uematsu-cho, Kiso-gun, Nagano Prefecture in Japan, in 1923 by relating to the feature of the building of the hydraulic power station and the architect, Shiro Sato. The hydraulic power station originally was a functional and industrial building which puts a priority on the efficiency of business economy, at the same time it was often required to present a beautiful appearance. The building of Momoyama hydraulic power station was founded on the crane girder structure covered with reinforced concrete(RC) walls. A Hat roof of RC slab was applied to the roof of the building. It was generally designed in Neo-Gothic style. More specifically, however, the wall surface was designed in church style and the upper part was like a castle in the middle ages. Therefore the total design was eclectic. The outer surfaces of the building were remained to be bare concrete as cast. Such a multiple building symbolizes the situation of Japanes architecture in the 1920s. 4 figs.

    For the baseline study in the monitoring gas hydrate test production in the Ulleung Basin, Korea Institute of Geoscience and Mineral Resources (KIGAM) has developed the KIGAM Seafloor Observation System (KISOS) for seafloor exploration using unmanned remotely operated vehicle connected with a ship by a cable. The KISOS consists of a transponder of an acoustic positioning system (USBL), a bottom finding pinger, still camera, video camera, water sampler, and measuring devices (methane, oxygen, CTD, and turbidity sensors) mounted on the unmanned ROV, and a sediment collecting device collecting sediment on the seafloor. It is very important to monitoring the environmental risks (gas leakage and production water/drilling mud discharge) which may be occurred during the gas hydrate test production drilling. The KISOS will be applied to solely conduct baseline study with the KIGAM seafloor monitoring system (KIMOS) of the Korean gas hydrate program in the future. The large scale of environmental monitoring program includes the environmental impact assessment such as seafloor disturbance and subsidence, detection of methane gas leakage around well and cold seep, methane bubbles and dissolved methane, change of marine environments, chemical factor variation of water column and seabed, diffusion of drilling mud and production water, and biological factors of biodiversity and marine habitats before and after drilling test well and nearby areas. The design of the baseline survey will be determined based on the result of SIMAP simulation in 2013. The baseline survey will be performed to provide the gas leakage and production water/drilling mud discharge before and after gas hydrate test production. The field data of the baseline study will be evaluated by the simulation and verification of SIMAP simulator in 2014. In the presentation, the authors would like introduce the configuration of KISOS and applicability to the seafloor observation for the gas hydrate test production in

    This paper summarizes the research result in fiscal 1997 from the basic research results on the commercialization of innovative energy technologies. The target of a photovoltaic power generation market includes isolated power sources (several kWp) for distant places or developing countries, and those (several tens kWp) for personal residences or public facilities. Although the former is mainly promoted in the West, while the latter over the world, their profitability is unsolved. Power plants over several hundreds kWp are in demonstration test. Solar heat power generation of several tens to hundreds MWp is most profitable, however, small-scale one is poor in feasibility. Australia takes an interest in distributed photovoltaic power generation directly connected with actual lives of residents, and has a dominant opinion that desert is useless as large-scale site. This country lays emphasis on protection and maintenance rather than positive use of desert based on a basic cognition that desert is easily changed and broken. The Australian government announced power company`s obligation to use renewable energy by 2%, and a strong organization is scheduled to be newly established. 59 figs., 57 tabs.

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

    Basic research is conducted on the Solvolysis liquefaction process for the purpose of producing from coal an ashless, low-sulfur, pollution-free liquid fuel. In the research on the Solvolysis liquefaction (1st stage liquefaction) of coal using a hydrogenation solvent, the Solvolysis liquefaction of coal is studied, for which a refined Solvolysis pitch containing coal substances and a hydride of solvent refined coal are used as Solvolysis liquefaction solvents for the 1st stage. In the research on the 1st stage liquefaction reaction conditions using a high-temperature closed process, two methods are employed. One is a method that uses a mini-pump type reactor in which a small hermetic container is submerged in a high-temperature solvent for rapid heating and the other is a method that uses a pipe type reactor in which coal slurry is caused to travel through a pipe heated to a high temperature. For the analysis of the 2nd stage liquefaction (hydrogenation) reaction conditions, the properties of the 2nd coal liquid, and the constitution of the 2nd coal liquid, and the for the research on the 1st stage liquefaction capacity, the hydrogenation of anthracene oil and solvent refined coal as recyclable solvent models is studied.

    Basic data for the above subject were collected through technical research on the melt welding of dissimilar metals and through conducting experiments under microgravity concerning the phenomenon of melt welding. The technical research covered reports published in the past 25 years on the welding or bonding of dissimilar materials. For each of the combinations of dissimilar materials of steel, nonferrous metal, and ceramics for producing a transitional joint, investigations were conducted as to whether dissimilar metal welding or bonding was currently feasible under each of the welding or bonding methods, and problems were extracted and remedies were gathered. No melt welding technology was found, however, capable of directly welding dissimilar materials for a transitional joint in which intermetallic compounds were to be formed. In a melt welding experiment conducted under microgravity, investigations were conducted into the effect of surface tension and gravity on convection inside a molten pool and into the bonding of dissimilar materials for which Al/Cu and Al/Mg were involved. It was then shown that microgravity is effective in mitigating stirring and segregation in a molten pool. (NEDO)

    For the work of searching for coal beds, comparison is made between the geological structure of the object area, which is predicted, before actual investigation, by a close scrutiny of the result of oceanic pilot boring conducted in the past, result of geophysical exploration, and the geological features of galleries already in presence in the vicinity, and the result obtained from galleries drilled actually for the investigation. The investigation was conducted at the Ikeshima coal mine, Nagasaki Prefecture. In this fiscal year, 5 investigation galleries were drilled, totalling 1640m in length, and, in the mine, geological surveys, survey and measurement, coal quality evaluation, water emergence investigation, boring for coal, etc., were carried out. Comparison was made, and, though in the 2nd Minami No. 06 air duct there was no important difference detected between the prediction and the actual result, some faults were found to exist which had not been predicted by seismic exploration on the ocean. In the 2nd Minami No. 5 air duct, the actual geology was not different from the predicted geology, this endorsing the usefulness of boring for coal. In the 2nd Minami No. 01 gallery, direction and inclination were not greatly different from what had been predicted, but some faults which had not been predicted were discovered. These faults had escaped the scrutiny of neighboring coal beds and pilot boring. (NEDO)

    In order to help discuss the measures to activate researches and developments in private corporations, surveys were made on barriers and factors related to industrial technology research and development by fields, and discussions were given on structuring research and development models. Factors impeding research and development processes relate to a case of each phase in the fundamental research, applied research, and product development, and a case of human resources, funds and information. A policy of structuring models was determined to make quantitative the effects of different aiding systems of the government for researches and developments in private corporations. Case analyses were conducted by using a pilot model. In the present research, a questionnaire survey was carried out to acquire such data as R and D time lag, and to identify the effects of the policies. Surveys were also performed on research and development programs in North America, by making interviews to concerned corporations. As a result of the surveys, such problems were extracted as research and development fund, freer flow of human resources, research and development systems, handling of results of researches performed by consortiums, accounting systems, and sale of the government owned patents.

    The basic experimental researches were carried out for coal liquefaction by solvolysis. The studied items include hydrogenation conditions for treating the primary liquefied products, asphalt, pitch and model solvents (e.g., anthracene oil) in the presence of a commercial catalyst, solvolysis conditions for finely divided, molten coal using a hydrogenation recycled solvent, hydrotreating solvents, analysis of solvolysis-liquefied products, and liquefaction capacity of fractionated solvents for finely divided, molten coal. The studied items for separation of minerals include settlement at high temperature of the solid residue from the first liquefaction stage, and changed coal particle size distribution as a result of the first-stage liquefaction reactions in the presence of a hydrogenation solvent. The experimental study results indicate that conversion of finely divided molten coal into asphaltenes and preasphaltenes is notably accelerated in the phase-II coal liquefaction process by solvolysis, when a hydrotreating solvent is used for the first stage solvolysis process.

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

    Efforts are made to develop a high-precision high-resolution seismic reflection method, high-efficiency method for measurement in the bored hole, coal potentiality assessment system, and so forth. For the development of the seismic reflection method, studies are conducted to properly deal with a situation where there are high-velocity layers at levels shallower than the object coal bed, and a conclusion is reached that quake generation based on the pseudorandom binary sequence code will be the best for the purpose. The system was tested for verification in a producing coal mine. As for measurement in the bored hole, an on-site test was conducted for a geophysical logging system capable of determining the total sulfur content, ash, and the like, and the system was found to supply high-quality data. In developing the coal potentiality assessment system, studies were made about the basic concept of the coordination of the system with the coal GIS (geographical information system) dealing with spatial data and about the functions of the system, and a conceptual design was prepared.

Among the projects having been performed by NEDO in commemoration of the 20th anniversary of the NEDO foundation, the economic and social situations in the times in which the projects have been carried out with the focus placed particularly on new energies were put into order and analyzed to make clear the positioning of the project significance in the nation's energy policies. In addition, the roles of NEDO were recognized afresh to use them as the fundamental materials to serve for the future policy development. For the past thirty years before and after the oil crises, the time division that can be used universally for the project evaluation was established, based on the trends inside and outside the country, social currents, related indexes, and the status of development execution. Work hypotheses were presented regarding the basic conception in the evaluation, specific evaluation viewpoints, and their contents. Based on the hypotheses, three subjects were taken up as representative cases, that is, photovoltaic power generation, coal liquefaction, and phosphoric acid type fuel cell technology development. Time points that are considered as the important turning points were specified to give evaluations at respective turning points. Analyses were also made on decision making factors for project planning, continuation, direction change, suspension, and completion. (NEDO)

    The development and utilization of new energy and reusable energy in China have greatly progressed for these 20 years, but it is necessary to further enhance the rate of these energy in the energy structure by heightening the conversion efficiency and reducing the production cost. As to the matured technology, it is necessary to attempt a large scale modernization and form a completed production/service system by making large breakthrough of new technology/new industrial art. For improvement of levels of a lot of new energy technology, emphasis should be placed on international cooperation, R and D, and model business. Together with the introduction of reusable energy such as photovoltaic, wind, geothermal and ocean power, the conventional low efficiency biomass utilization system is converted one after another. The development/spread of clean coal technology are promoted, and the rate of the hydroelectric/atomic power generation is heightened. By 2010, the full-scale application/spread of new energy technology should be advanced, and the technology and production of the world top level should be realized. It is necessary to make the energy consumption clean and promote the continuously harmonized growth of economy, society and environment. (NEDO)

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

    A technology is developed to produce useful gases such as acetylene, hydrogen, and carbon monoxide from coal and coal-related substances making use of the high-temperature high-density energy of plasma jets. Using the newly developed systems, the energy utilization rate is 50% or higher and the yields are 60-100g/kWh for acetylene and 100-160l/kWh for hydrogen. For the achievement of the goal, two types of plasma gasification systems have been developed. One is a '100kW 3-torch plasma gasification system' in which the specimen for gasification is fed to the center of the combined flame for improvement on the contact rate between the specimen and plasma flame. The other is a 'rotating plasma torch system' in which the flame is rotated, and expanded, by an externally provided magnetic field for improvement on the contact rate between the specimen and plasma flame and, simultaneously, for an increase in energy utilization efficiency by feeding the specimen into the discharge region. In this fiscal year, quenching tests are conducted using water and oil so as to establish the difference in quenching effect between quenching agents. What to improve in the systems are clarified.

The carbon conversion rate turns out to be approximately 37% for the gas, approximately 53% for the residual char, and approximately 10% for a mixture of tar, naphthalene, benzene, phenol, etc. Hydrogen is produced making use of the residual char when a small amount of coal is added, and it is deemed that the first experiment for the development of a moving bed hydrogasification process has been successfully completed. In the study of the mechanism of hydrogasification reaction, the result of a preliminary experiment in a fixed bed pressurized gasification furnace is compared with the data from a continuous gasification experiment, and the relationship is determined between the coal feed rate and the reaction rate. Conducted besides are a basic study of problems relating to operation, basic research on a reaction mechanism (carbonization by rapid heating), estimation of the equilibrium composition of gas generated by coal gasification, etc. (NEDO)

    A field survey was conducted with the aim of commercializing innovative energy technology in the Tibet district. The survey included the energy supply/demand situation and supply plan and the situation of new energy utilization in the Tibet district. And, based on the concrete circumstances in the Tibet district, a realistic plan was presented for solution to the energy supply/demand problem. To carry out the project, used are a lot of solar energy and wind power energy resources which are abundant in Tibet. In about 5 years, 100 sets of village use system and 80,000 sets of household use system are to be installed, which solves the problem on electric power demand in a part of the non-electrified houses. Accordingly, farmers/stockbreeders living in the non-electrified region will alter their life patterns which are closed and behind other countries, get out of the poverty, basically enhance the quality of life, promote the communication of various knowledge/information of scientific technology, renew their life/production concepts, and heighten the production efficiency for the wealthy society. The project itself belongs to the construction for protection of ecological environment. It produces no exhaust gas/solid waste which do harm to the environment. The ecological environment efficiency is very high. (NEDO)

    At the Ensham open-cut mine in Australia, an investigational survey was conducted of a new rehabilitation technology which can contribute also to securing CO sink with the aim of preventing global warming, and the FY 2000 results were summed up. In the survey, the surface soil, sand silt layer, brown rock layer, gray sandstone layer and coal seam were moved from open pits, the goaf was embanked, and the experimental section was set up. As to the place for test, conducted were collection of information on adaptive plant species, bacterium species, meteorology and precipitation pattern, soil analysis, etc. Concerning the bacteria, bacteria were newly separated and tested at the survey site, besides the species to be tested. After planting, measurement of the growth amount of plants, etc. were conducted grasping the meteorology and the water-pouring state during cultivation. For the basement, three kinds of spoils were used, and permeability is different in each spoil. Permeability is an important factor to plants. Too good permeability and too bad permeability are both not good. A future follow-up survey will make what kind of spoil is suitable for eucalypti possible. (NEDO)

    Efforts are made to develop a high-precision high-resolution seismic reflection method, high-efficiency method for measurement in the bored hole, coal potentiality assessment system, and so forth. For the development of the seismic reflection method, studies are conducted to properly deal with a situation where there are high-velocity layers at levels shallower than the object coal bed, and a conclusion is reached that quake generation based on the pseudorandom binary sequence code will be the best for the purpose. The system was tested for verification in a producing coal mine. As for measurement in the bored hole, an on-site test was conducted for a geophysical logging system capable of determining the total sulfur content, ash, and the like, and the system was found to supply high-quality data. In developing the coal potentiality assessment system, studies were made about the basic concept of the coordination of the system with the coal GIS (geographical information system) dealing with spatial data and about the functions of the system, and a conceptual design was prepared.

    This report summarizes the research result on development of new coal exploration technology. For a high-precision and high-resolution reflective seismic exploration system, R and D was made on the exploration technology of several meter in resolution for medium-depth (800m) coal deposits under a lake of 2m deep. As a result, the high-frequency and high-power source (150-200Hz in dominant frequency, 700-800m in penetrability) and the high-frequency and high sensitivity receiver (10-1000Hz in frequency band, 35V/PA in sensitivity) were developed successfully, and the positioning system was improved. The final evaluation of these elementary technologies was carried out through demonstration tests, resulting in satisfactory results. For a high-efficiency trial drilling system, the in-bore trouble prevention system for measurement, processing and analysis of drilling data (drilling length, drilling rate, revolution, bit load, torque) and drilling mud data (charge water pressure, charge/discharge water, density, pH, viscosity) was constructed. The outlook for low-cost measurement and a safety during drilling was thus obtained. (NEDO)

    Investigations and discussions were given on a project to implement district heating, greenhouse heating, and binary power generation by utilizing geothermal resources in Hungary. Hungary has deep earth pressure type hot water areas distributed, that flow hot water of about 90 to 180 degrees C by the bed pressure. The areas that can utilize the hot water were extracted and investigated by using literatures and data. The project plans district heating of about 15,000 households using the geothermal water, heating of greenhouses equivalent to 100,000 m{sup 2}, gas engine power generation by using the flowing fluid pressure and combustion of the generated methane gas, and binary power generation by using the geothermal water. As a result of the discussions, it was revealed that the energy saving effect would save 5,008 Ktoe in 20 years as converted to crude oil, and the greenhouse effect gas reducing effect would reduce 14.2 million t-CO2 in 20 years. The total project cost would be about 16.62 billion yen. The internal profit rate of this project is 11.34%, largely exceeding the opportunity cost, and indicating the financial effect possibility.

    Technical trends were surveyed concerning the recovery and the use as fuel of low-concentration methane gas or the like contained in the air ventilated out of coal mines. Methane gas recovery technologies include high-temperature incinerators and catalytic incinerators designed to collect heat, method of conversion of methane to CO2 using microbes named methanotrophs, and adsorption methods using activated charcoal, zeolite, or the like. Among technologies that have reached a practical level in the utilization of mine methane gas, there are the temperature regenerative flow-reversal reactor (TFRR) and the catalytic flow-reversal reactor (CFRR) utilizing high-temperature oxidation reaction. TFRR has been reported effective by MEGTEC System after a 6-month operational test of a 3.0m{sup 3}/s plant at a British coal mine. Test and research are over with CFRR, which is now ready for a commercial scale verification test. Recovery by adsorption, though worth further research efforts, is economically away from commercialization at the present stage, and wants more studies of adsorbents, etc. (NEDO)

    As a part of development of the energy conservation technology database, revision was made on 'Directory of Energy Conservation Technology in Japan' which was published to present the energy conservation technology of the Japanese energy-intensive industry to Asian countries in fiscal 1996. The previous directory was composed of 307 technical items, and 126 items among them were deleted and new 63 items were added through this revision. The technologies with energy conservation effects more than 10% were mainly selected by knowledge of the industrial members of the committee and other specialists. The energy conservation effect widely ranges from low-level one to high-level one, and the number of all the energy conservation technologies is enormous. Consequently, it should be considered that the applicable extent of the energy conservation technologies is dependent on the energy cost or economical situation of Japan and developing countries.

    Short-circuited metals have a considerable effect on the electrochemical reaction in the contact corrosion of different metals. The origin of different metal contact corrosion, effect of area ratio, effect of cathode metal, effects of the concentration and pH of dissolved ions, and corrosion prevention methods are discussed. Atmospheric corrosion varies widely in accordance with the type of environment. Major atmospheric corrosion are classified into those in coastal region, industrial zone, rural area, city area, the tropics, and the frozen zones. Moisture in the air has a big influence on the atmospheric corrosion. Vernon has found the presence of a certain critical humidity at which corrosion rate increases rapidly in the atmospheric corrosion. Long term atmospheric corrosion as well as addition of alloy elements and coating as corrosion protecting methods are discussed. Corrosion by sea water is classified into corrosion by oceanic atmosphere, splash area, tidal zone, and mud layer. Corrosion of metals in soil is influenced by many factors such as moisture resistivity, moisture, air permeability, pH, and property of soil. Pitting corrosion, crevice corrosion, and stress corrosion are outlined. 61 refs., 32 figs., 12 tabs.

    This paper evaluates influences of stacking of incident angles against the reflecting surface on the resolution. Basic equations for evaluating the influences were deduced. A simple evaluation method has been provided using these equations. The present evaluation method is considered to be useful for acquisition design, processing, and interpretation of data as an indicator. According to the equations introduced in this study, there are some demerits for stacking traces whose incident angles were large. A total reflection region often appears due to the decreased resolution, and the vertical resolution decreases prior to stacking. Occasionally, it is not effective to remove traces having large incident angles from the viewpoint of resolution. In practice, the selection of most suitable trace through trial and error is not easy due to difference in individual regions. An evaluation method must be discussed, by which the optimal trace can be selected automatically during the data processing. 6 refs., 15 figs.

    A giant star-forming region in a metal-poor dwarf galaxy has been observed in optical lines with the 10 m Gran Telescopio Canarias (GTC) and in the emission line of CO(1–0) with the Northern Extended Millimeter Array (NOEMA) mm-wave interferometer. The metallicity was determined to be 12+{log}({{O}}/{{H}})=7.83+/- 0.09, from which we estimate a conversion factor of α CO ∼ 100 M ⊙ pc‑2(K km s‑1)‑1 and a molecular cloud mass of ∼2.9 × 107 M ⊙. This is an enormous concentration of molecular mass at one end of a small galaxy, suggesting a recent accretion. The molecular cloud properties seem normal: the surface density, 120 M ⊙ pc‑2, is comparable to that of a standard giant molecular cloud; the cloud’s virial ratio of ∼1.8 is in the star formation range; and the gas consumption time, 0.5 Gyr, at the present star formation rate is typical for molecular regions. The low metallicity implies that the cloud has an average visual extinction of only 0.8 mag, which is close to the threshold for molecule formation. With such an extinction threshold, molecular clouds in metal-poor regions should have high surface densities and high internal pressures. If high pressure is associated with the formation of massive clusters, then metal-poor galaxies such as dwarfs in the early universe could have been the hosts of metal-poor globular clusters.

    In this paper, principles and characteristics of resistivity tomography are outlined, and its application examples are described. Resistivity tomography is a technology to measure electric potential of many electrodes placed on the earth {prime} s surface or in the well and to analyze the resistivity distribution in the objective area. Arrangement of electrodes (current electrodes and potential electrodes) is determined taking account of the sensitivity distribution. Also, measurements need to be done not only between the surface and a borehole and between boreholes, but also along the wall of a borehole. After the measured data are corrected according to the influence of topography, the initial model is revised repeatedly with the Alpha Center method, and then, resistivity distribution maps are obtained. As an example of field application of resistivity tomography, a geological survey using three boreholes at the scheduled construction site for a dam is described. In this survey, distribution conditions of surface soil, gravel, and andesite were confirmed, and the results almost agreed with the results of seismic tomography. Moreover, another survey with resistivity tomography was carried out at the test site of hot dry rock power generation in Yamagata Prefecture. There, conductive solution was injected from the borehole after hydraulic fracturing, and cracking conditions of rocks were investigated. 28 refs., 21 figs., 1 tab.

    In order to demonstrate the power transmission using microwave and arrange advantages and problems in the wireless power transmission, field tests of point-to-point power transmission were conducted. Microwave frequency of 2.45 GHz was used, which is assigned as the industrial, scientific and medical frequency. The transmission system is composed of generator, director tube, primary radiator, and transmission antenna. The maximum 5 kW of microwave power can be transmitted by combining a 3 m-diameter parabolic antenna and a magnetron. The receiving system is composed of devices called as RECTENNA (rectifying antenna). A large capacity and high efficiency RECTENNA was developed, by which the maximum 2.5 W of input power per single device can be provided. As a result of the experiments, efficiency at the transmission side was over 70%, and RF-DC efficiency at the receiving side was about 51%. At the open-air test site, however, the total efficiency of only 14.8% could be obtained. 8 refs., 12 figs.

    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.

    Anisotropy has been investigated using S-wave as a technique for detecting fractures. In this study, fundamental experiments were carried out with slightly changing the measuring conditions at a place where anisotropy was expected. This paper describes the fundamental data acquisition of anisotropy analysis using S-wave, and a part of the results. The experiments were conducted on the agricultural road in Yamadera district, Matsuyama-machi, Yamagata Prefecture. Two flat unpaved roads meeting at right angles were used as traverse lines. In this place, several reflection surfaces were certainly detected by P-wave, and anisotropy of S-wave was confirmed from the velocity of refracted wave of S-wave. Data were processed for individual traverse lines meeting at right angles. Firstly, signal sweeping, correlation, and vertical superposition were made. Six kinds of data were prepared, i.e., three-component receiving records of data at 0{degree} of generating direction and three-component receiving records of data at 90{degree} of generating direction. Records of T-component at 0{degree} and R-component at 90{degree} were used for processing of the seismic reflection method. These records would be considered to be data of SH-wave and SV-wave, respectively. 4 figs.

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

    A concept of a system is constructed in which a series of the flow from the construction of structures to the shape and control in structural phase, repair, and dismantlement is made effective and controllable by giving a function of intelligent structure to structural systems in aerospace/architecture/civil engineering fields. For it, fundamental technologies required for the systems were extracted for construction of the technology system. Further, in relation to the intelligent machinery system including the control method, manipulation, and communication of the structure under the micro-gravity environment required for this system, the basic experiment was conducted at the ground gravity-free experimental center to acquire the effective data. As to the base technology, three fields were studied of the intelligent machinery system including the behavior/control of materials and structure, intelligent robot, and communication. In the experiment on micro-gravity environment, experiments were carried out on the behavior of micro-gravity rover for small planetary probe, inter-satellite group communication, capture of trouble-satellite, development of inflatable structure, and hopping robot.

The photosynthesis under the sea, which is different from that on the land, is judged to be made by taking in HCO3[sup -] and converting it into CO2 inside the plant. Porphyra yezoensis which is seaweed is cultivated as comestible. With a rise in CO2 content, the growth in length of leaves was observed to be accelerated through ventilating Porphyra yezoensis with the three test types of air which respectively contained 350ppm (atmospheric CO2 content), 1000ppm and 1600ppm CO2. As a result of measuring the photosynthesis speed by the generated quantity of O2, it was heightened with a rise in dissolved inorganic carbonic acid content of the sea water. Measurement was also made of daily fluctuation in calcification speed by Corallina officinalis capable of calcification by ventilating it with 350ppm and 1600ppm CO2. In case of 1600ppm, the sedimentation of CaCO3 was prevented. In case of 350ppm, the sedimentation was quantitatively larger during the bright period than that during the dark period. The growth of Gracilaria gigas which is an agar material was compared by changing the above CO2 levels. In case of 1600ppm, the weight grew to 2.3 times in 20 days. 16 figs., 2 tabs.

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

    The electric system of a solar vehicle was removed and the fundamental characteristics examined in order to carry out a basic experiment on the electric system. Using a basic circuit with panels, batteries and loads connected, the voltage and current were measured in the presence/absence of the trackers, batteries, etc., and then, their effects were examined. Simultaneously, the quantity of solar radiation was also measured. The lowering of the output voltage was somewhat relaxed with the use of the trackers. Further, with the trackers used, the output voltage of the panel was small in spite of a large quantity of solar radiation compared to the case without the trackers, which was due to the restriction of the output voltage by the trackers. When measured without batteries, the output voltage of the panel was such that the load current was also influenced by the variation of insolation, so that, with a large decrease in insolation, the load current was decreased with the supply of current suspended from the panel. 7 figs., 1 tab.

    Investigations and discussions were given by using P-S logging on anisotropy of refracted waves in the fundamental experiments conducted in the Matsuyama town, Yamagata Prefecture. In the investigations, S-wave was transmitted into two to three directions at four locations in total: one at the opening of a well with a depth of 100 m and three locations having offset of 50 m from the well opening, and anisotropy of direct waves in the depth direction was investigated. Data were recorded on the ground at the same time by using a 3-component receiver. As a result of the experiment, detection of the anisotropy by means of measurement inside the well was found more difficult than anticipated due to anomaly in the refracted waves, hence no clear velocity anisotropy has been observed. It appears that no azimuth anisotropy exists at depths shallower than at least 24 m. No anisotropy due to incident angles was made clear in the present experiment. Offset recording experienced poor S/N ratio, having made the data analysis difficult. The data for zero offset do not harmonize with the refracted wave analysis on the data derived by using the reflection method, whose cause requires further discussions. 4 figs., 2 tabs.

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

    With respect to concept of resolution in seismic exploration using the reflection method, detailed considerations were given on processes of forming the resolution as a result of arranging observation points at vibration transmitting and receiving points. In the discussion, numerical experiments were carried out, in which the scattering stacking process is applied in a model having one scatterer existing in homogeneous media. The experiments investigated an imaging formation process of the scatterer when arrangement of the vibration transmitting and receiving points were changed from a coarse condition to a dense condition while the number of transmitting and receiving points is being increased. Resolution is created if waveforms having finite frequencies are used as input, and the imaging is performed by utilizing the limited number of vibration receiving and transmitting points. If the concept of equi-travel plane is used under these conditions, the equi-travel planes perform negation with each other, and it was indicated that visual resolution is expressed by how good the negating effect is. It was discovered that such concept of the resolution is quite ambiguous in terms of engineerings. 2 refs., 17 figs.

    In Estimation Work 1, the potentially available amount (the amount in existence) is determined for each type of new energy by use of various new energy related technologies now available. In Estimation Work 2, the available amount is determined for each type of new energy, with social restraint and installation space taken into consideration. Effects upon energy saving and CO2 emission reduction are 4405.2% and 3439.1% in Estimation Work 1, and 6.5% and 8.0% in Estimation Work 2. A conclusion is reached after examining the outcomes of the said estimation works and the results of simulations (conducted on the assumption of new energy introduction in fiscal 2010), the number of advocates expressing their support of new energy adoption in questionnaires answered by various businesses and offices in the prefecture, high possibilities of introduction detected in a survey of exploitation projects of cities, towns, associations, and unions, and the prospect of acceptance by households. The conclusion is that the types of new energy and technologies to be selectively introduced into the prefecture will be photovoltaic power generation, wind power generation, clean energy vehicles, energy extracted from wastes, cogeneration, fuel cells, passive solar system, utilization of waste heat from factories and mills, and ocean energy. These are abundant in terms of potentially available amount and of available amount. (NEDO)

    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.

    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.

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.

    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.

    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.

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.

    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.

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

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

This 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.

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

    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 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 explains basic studies on characteristics of coal char gasification under pressure. Hydro-gasification of coal needs as a gasifying agent a large amount of hydrogen, which is effectively produced by the water gasification of exhaust unreacted residual char. In fiscal 1975, gasification was tested on Taiheiyo coal carbonized char by an atmospheric fluidized gasifier of 28 mm bore. In fiscal 1976, experiment was conducted under pressure by fully improving the auxiliary safety equipment. The char and gas yield increased with higher pressure in pressurized carbonization by an autoclave. In fiscal 1977, clinker was successfully prevented by using quartz sand for a fluidized medium. In fiscal 1978, two-stage continuous gasification was examined. In fiscal 1979, correlation was determined between operation factors such as gasification pressure, temperature, etc., and clinker formation/char reactivity. An experiment was conducted for particle pop-out using a pressurized fluidized bed of 100 mm inner diameter, with the pop-out quantity found to be proportional to the 0.38th power of a pressure. A high pressure fluidized gasifier was built having a char processing capacity of 1 t/day, 20 atmospheric pressure, and an inner diameter of 100 mm. In fiscal 1980, this device was continuously operated, elucidating problems for the practicability. (NEDO)

    To construct vegetable factories in the Touhoku region, items of information have been collected with respect to items to be cultured and market conditions. Experimental discussions have also been given on new culture items and methods for utilizing snow. Using the results of investigations on the market conditions and weather environments, the following three kinds of spicy vegetables were selected: water cress which grows in about 46 culture days after seeding and in about 36 days by herbaceous cutting to a harvest of about 700 g/m{sup 2}, green perilla which grows in about 85 culture days to a number of salable leaves of 100 per stock, with an average leaf area of about 55 cm{sup 2}, and trefoil which grows in about 56 culture days to a harvest of about 5100 g/m{sup 2}. According to a storage experiment using snow, lettuce packed with snow in a box retained at a temperature of 5{degree}C and a humidity of 100%, pre-cooled for one day and then stored for six days in a refrigerator at 5{degree}C presented very little decrease in fresh weight and no decrease in freshness. The same result was obtained also for the Sunny Lettuce. 9 refs., 19 figs., 9 tabs.

    The conceptual model and feasibility of the hybrid energy system for residences and public facilities in snowy cold regions were studied. Based on the existing data, the existing and available amounts of natural energy and unused energy in the target area, Sapporo were estimated. Based on the predicted energy demands of 4 kinds of building models, the energy systems for such models were studied. The use of the following energies was considered: photovoltaic power generation and solar heat for all the models, household sewage energy for the multiple-dwelling house model, and wind power generation for the public facility model. The annual energy balance was calculated to evaluate it. The use of additional commercial electricity was necessary, while surplus solar heat energy was found in summer which can push up the self-sufficiency rates of the residence and public facility models to 70% and 44%, respectively. The multiple- dwelling house model which can use a large amount of household sewage energy could utilize 80% of new energy, while the other 3 models utilized only 60-70% of that. 81 figs., 42 tabs.

    For working out and proposing project themes optimum for the popularization of technologies for effectively utilizing energy in India, a basic survey was conducted into India's energy policy, trend of supply and demand, steelmaking industry, papermaking industry, petrochemical industry, and chemical fertilizer making industry. India in fiscal 1997 consumed 374-million tons of energy in terms of oil, 30% in oil and 63% in coal. Activities were vigorous for the development of oil substitutes such as photovoltaic and wind power. The steelmaking industry that produced 22.12-million tons in fiscal 1996 was found to suffer from a reduced operating rate due to aging of facilities and from poor infrastructures such as harbor and railway facilities wanting maintenance. It was inferred that energy conservation facilities and technologies of Japan's steelmaking industry would work effectively. The cement making industry was found modernized, but faced the problem of the high cost of electric power. The papermaking industry was busy enhancing its own production capability. The fertilizer making industry ranked third in the world in terms of production, but the energy consumption rate at its ammonia plant was too high. The petrochemical industry was well developed, with Japan's technologies incorporated into it in the design stage. (NEDO)

    Experiments were conducted on the plasticity processing of heat resistant ceramics making use of the viscous deformation of amorphous ceramics in the supercooled liquid temperature domain. Concerning the preparation of powder of amorphous ceramics, the plasma rotating electrode method of Institute for Materials Research, Tohoku University, was employed, and a bamboo leaf shaped amorphous flake was successfully fabricated by increasing the arc discharge current. In a search of texture easy to turn amorphous, it was observed that Al{sub 2}O{sub 3}-La{sub 2}O{sub 3} had a supercooled liquid domain of as large as 70K, and this enabled a conclusion that it was a promising candidate for hot molding in a supercooled liquid domain. In an experiment of molding in a supercooled liquid domain, Al{sub 2}O{sub 3}-Gd{sub 2}O{sub 3} was used in a press molding process. As the result, a compact bulk mold was obtained in a temperature domain far lower than in the case of conventional sintering. Crystallization had already advanced in all the molds experimentally fabricated by press molding, and this disabled a study of characteristics to be exhibited by an amorphous mold, but it was found that they had a compressive strength of approximately 1,800MPa.

    The 40 'Surveys for promotion of joint implementation, etc.' conducted by NEDO (New Energy and Industrial Technology Development Organization) in fiscal 1998 aimed to pick out projects that would positively utilize the flexible measures (three Kyoto mechanisms) for the achievement of greenhouse gas reduction targets defined at COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change). In this paper, concerning these 40 surveys, studies are conducted for reaching conclusions about setting baselines for the future, execution of similar feasibility studies in the future, application of flexible measures, and opinions towards project implementation. The 40 surveys were, concretely speaking, conducted not to work out policies for actualization of given projects but to consider philosophies of project actualization and baseline formation for the future. In this paper, project outlines, environmental impact assessment, and economic assessment (investment assessment) are put in order for each of the surveys, and relations between amounts of global warming gas reduced and project costs, and project profitability, are analyzed for each of the surveys.

    From the viewpoints of realization of mass transportation, improvement of space factor in buildings, transportation systems in buildings are surveyed to compare the characteristics. Then, a loop-type independently-driven multiple-cage elevator (circulating elevator) system is proposed to estimate its transportation capacity, and necessary data for realizing transportation capacity higher than twice that of the conventional elevator are presented. As regards operational control, a high efficient control method is proposed which can restrain needless stops particular to the multiple-cage system and improve the waiting time and round trip time, and the result of the investigation by simulation is reported. Basic operation method of the loop-type elevator is determined, and the transportation capacity is estimated by simulation. The application in which the loop-type elevator can exhibit the best performance is its use in 15 floor-class buildings or for local bank zones in large-scale buildings in a system combined with the shuttle system. 9 refs., 12 figs., 5 tabs.

    For the construction of a coal mine assessment technology system, surveys are conducted on the current state and technology trends of resources-related GIS (geographical information system) in other countries. When one ponders over coal-rich areas to be newly explored and developed in one's study on the stable exploitation of coal abroad and its import to this country, what interests one gradually shifts from known superior large-scale coal mine areas to next-generation coal mine areas yet to be exploited. Accordingly, it is mandatory to build an assessment-oriented comprehensive technology system capable of promptly dealing with any changes in natural, geological conditions that may be presented by coal mines to be exploited. Although GIS is recognized as a useful means not only in the field of natural science but also in other fields whose data may be plotted on a map, its position is not yet established when it comes to coal resources. It is therefore necessary to promptly introduce GIS into the field of coal. In fiscal 1998, on-site surveys were conducted not only in Japan but also in the U.S., Canada, and Australia who are senior to Japan in terms of GIS application. Also, information was collected from literature and via Internet, surveys were conducted about the use of GIS in the field of earth science especially in the field of coal resources, and the state of the digital data utilizing setup indispensable for the proper operation of GIS was investigated.

    The study of pressurized fluidized gasification of coal chars started in fiscal 1975, and a 0.2t/d unit was in operation until fiscal 1979. Since fiscal 1980, a 1t/d unit has been in operation. In fiscal 1984, an entrained bed gasification furnace was constructed, capable of high-temperature gasification of various coals, and it is now undergoing a test operation. This report consists of pressurized gasification tests for coal char, the result of a study on the effect of coal type on the char gasification reaction rate, and the result of experiments on the treatment of coal liquefaction residue, all accomplished in the 1t/d gasification unit. For the investigation of the effect of coal type, chars of 13 types of coals are subjected to reaction tests in the carbon dioxide gas, and weight reduction rates and changes in residue surface areas are determined while reaction is under way. The results are analyzed and parameters are made clear that enable a quantitative assessment of the effect of coal type on gasification reaction rates. Pulverized grains and coal liquefaction residue are blended and gasified in the fluidized bed in the presence of oxygen and steam. As the result, a gas capable of 2,000kcal/Nm{sup 3} containing 30% hydrogen and 25% carbon monoxide is acquired, when catalyst grains in the residue are segregated. (NEDO)

    Research was made to promote Activities Implemented Jointly Japan Program. Joint Implementation (JI) is the methodology for preventing global climate changes by collaboration of countries. The countries take cooperative actions for reduction, absorption and fixation of greenhouse gases, and effectively distribute the reduction credits among relevant parties. This was decided in the first session of the Conference of Parties (COP) held in March, 1995. In COP3, Japan`s assigned reduction amount in 2008-2012 was determined as 6% of the emission level in 1990. The protocol defines JI between parties as dealings of emission reduction units, and JI between developing countries as clean development mechanism. The rules for a base line and credit distribution are necessary before full-scale implementation. Although JI is regarded as an important cost-effective project, it is important to decide where and how the JI projects should been promoted. The present state and issues of the primary approved project of Japan Program are arranged. In particular, various terms related to developing countries remain to be solved. 21 figs., 32 tabs.

    CO2 fixed in organic matters return to the atmosphere after putrefication and decomposition, but it is also known that CO2 fixed in inorganic shells stays there permanently. A study is made in this report about the fixation of CO2 in organic matters by use of the ulva and anchored diatom known to be high in CO2 trapping capability, and the study also covers the raising of shells aiming at the fixation of CO2 in inorganic matters. The ulva is raised in a cylindrical raceway type culture water tank, and the anchored diatom in a cylindrical culture unit, and breeding conditions under which they multiply at the highest rate are determined. Their CO2 fixation rates are, respectively, 92.76mg/liter/day and 25.45mg/liter/day, which may be converted, respectively, into 147.1 ton and 5.8 ton of CO2 per hectare per year. Fixed CO2 amounts are tentatively calculated using the above-said figures combined with the raising of shells, and it is found that CO2 may be effectively fixed when the ulva is raised in a 1-hectare area and the shells in a 3.63-hectare area. In this case, the annual CO2 fixation amounts are estimated at 74.1 ton in inorganic matters and 3.9 ton in organic matters. 6 figs.

    For working out and proposing project themes optimum for the popularization of technologies for effectively utilizing energy in four countries in Central Asia (Kazakhstan, Uzbekistan, Turkmenistan, and Azerbaijan), basic surveys were conducted into their energy policies, trends of supply and demand, electric power industry, metal refining industry, and cement making industry. Common to the four nations were that they were rich in energy resources (natural gas, oil, and coal) but that they failed to utilize them effectively despite of an increase in the yields. Incomplete infrastructures and delay in the implementation of energy measures attracted attention. A higher priority was found attached to the upgrading of and investment in structures, renewal of facilities, and the intensification of management. The basic industries wanted the modernization of their facilities and processes. As for electric power consumption, Kazakhstan consumed 53.0-billion kWh, Uzbekistan 39.0-billion kWh, Turkmenistan 4.4-billion kWh, and Azerbaijan 16.4-billion kWh. In Uzbekistan, where the nonferrous metal refining industry led its national economy, the energy consumption rate was found to be quite high. There was a decrease in production in the cement making industry. (NEDO)

    Lateral loading test of full-scaled pile foundation was made up to the ultimate limit state to establish a limit state design method for pile foundations. A full-scaled 3-by-3 pile group driven as bridge foundation was used for the test. A surface reclaimed layer is nearly 13cm in thickness. The lateral unidirectional loading test was repeatedly carried out by using 6 hydraulic jacks at 30MN in maximum load capacity and 50cm in maximum allowable deformation. The test and analysis results are as follows. In a range of 0-40% in pile head displacement/pile diameter ratio, a load-carrying capacity increased gradually. The yield point of a load-displacement curve agreed with the point at which a reinforcing bar of a pile body reaches analytical yield stress. Bending moment of a pile body and shear stress of a pile head increased in the order of back, middle and front rows. It was confirmed that a framework analysis method considering the non-linearity of a pile body and bedrock is also applicable to full-scaled pile group foundations. 17 refs., 32 figs., 3 tabs.

    Study was made on a thermally regenerative fuel cell using solar heat. The thermally regenerative fuel cell was devised which is composed of 2-propanol liquid-phase endothermic dehydrogenation at nearly 100degC, and acetone liquid- phase exothermic hydrogenation at nearly 30degC as reverse reaction. This low-temperature dehydrogenation can relatively easily utilize a flat solar heat concentrator. 2-propanol dehydrogenation generates acetone and hydrogen. Generated acetone generates electric power in hydrogenation, generating propanol. This propanol regenerates acetone and hydrogen in dehydrogenation. The activity of Ru and Pt composite catalyst was considerably higher than that of Ru or Pt single catalyst. The activity was also higher in carbon felt or carbon cloth carrier than carbon plate carrier. The open circuit voltage of the fuel cell was estimated to be 110-120mV, nearly consisting with theoretical values. Short circuit current was also estimated to be 9-11mA, suggesting reduction of its internal resistance as an important subject. 4 refs., 5 figs., 2 tabs.

    For prevention of global warming by greenhouse effect gas, study was made on energy saving measures for Achinsk refinery in Russia. Achinsk refinery is a relatively new plant put into operation in 1983, however, because of no various equipment for use combustion heat effectively, its average thermal efficiency is as low as 60%-70%, resulting in fuel consumption more than necessary one. Based on the study result, the following remodeling designs were made: Improvement of a heat exchange efficiency by relocation of heat exchangers to reduce fuel consumption of a heating furnace as much as possible, conversion of an existing heating furnace based on an old design concept to an advanced one, installation of a waste heat recovery system including a preheating convection unit and air preheater, reinforcement of heating furnace wall insulator, installation of an optimum control system for furnace operation, and improvement of a fuel supply system efficiency. This design showed possible reduction of heating furnace load, and possible furnace thermal efficiency of 90%. (NEDO)

    For working out and proposing project themes optimum for the popularization of technologies for effectively utilizing energy in China, a basic survey was conducted on China's energy policy, trend of supply and demand, cement making industry, non-ferrous metal industry, chemical industry, and electric power industry. The amount of primary energy produced in China in fiscal 1997 was 1.4-billion tons in terms of standard coal, ranking third in the world. It produced 1.4-billion tons of coke making coal, 160-million tons of oil, and 110-million kWh of electric power. In spite of its continuous efforts to develop oil and in particular natural gas, it has now turned an oil importing country. There was an increase in production in the industries surveyed, but energy efficiency was low because of their small-scale old-fashioned processes. In the cement making industry, 86% of the facilities presented some problems, and the non-ferrous industry was planning to rebuild itself into large-scale advanced-process plants. As for the chemical industry, investigations were conducted into the oil refining, petrochemical, and chemical fertilizer making industries. The electric power industry had facilities for 277GW, 210GW in thermoelectric power generation and 65GW in hydroelectric power generation. The thermoelectric power plants were found to emit great quantities of smoke and sulfuric oxides into the air. (NEDO)

    Medical application of lasers is rapidly expanding in accordance with the development of laser technology. However, it is difficult to predict how light propagates and is absorbed by living bodies because of strong scattering of light by biological tissues. Therefore, the determination of light dose has been based on experience. This fundamental study aims to develop a imaging simulator which can predict propagation of light and its effectiveness in medical diagnostics and therapeutics. Teoretical models of light propagation in biological tissues have been constructed, and experiments have been conducted to validate the theoretical calculation. In the theoretical calculation, a three-dimensional model which simulates a human head with five layers of different tissue types. Numerical calculation has been done by using the finite element method to simulate the propagation of ultrashort pulse light, and it is shown by a computer graphics technique for the first time in the world. In the experiment, a solid phantom which anatomically and optically simulates a human head based on MRI images has been fabricated by using the optical prototyping technology for the first time in the world again. Also, we have compared the experimental results of the transmitted light through the solid phantoms with the theoretical results and have succeeded in reconstructing the tomographic images of optical properties.

    CO2 laser beam has been applied to cut of the aluminum alloy. Average cut width, roughness of cut surface and average thickness of heat affected zone are investigated as functions of laser power, cutting speed and assist gas pressure. The average cut width increases with laser power, but it does not depend on the cutting speed. The narrowest average cut width obtained is 0.22mm under the conditions of laser power of 900W and cutting speeds from 600 to 1000mm/min. The roughness of cut surface decreases with decreasing cutting speed. The best smoothness of cut surface obtained is 17 {mu}m (Rmax) , when the conditions are 1100W and 600mm/min. The average thickness of heat affected zone decreases with increasing assist gas pressure. CO2 laser beam cutting is applicable to flash removal from aluminum alloy casting. This process is expected to reduce the need of physical labor and to improve the working conditions in the foundry industry. 32 refs., 10 figs., 2 tabs.

    Sabae city, Fukui Prefecture, has worked out a regional new energy vision for which the inhabitants, industrialists, and administrators combined their efforts to build a daily life related culture, friendly to environments and peculiar to the locality. The fruits of their activities are summarized in five chapters, which are (1) the basic philosophy, (2) survey of the amounts of new energy in existence, (3) survey of the amount of energy demanded, (4) various surveys conducted with the participation of the citizenry, (5) and summarization of important topics. Discussed in chapter (2) is the basic policy toward reckoning the amounts of new energy in existence, such as photovoltaic energy, solar heat energy, wind energy, hydraulic energy, temperature difference energy, and other energy resources remaining to be utilized. It states that they, when converted into electric power, 2.0 times 10{sup 8} kWh/year will be available and, when converted into heat energy, 2.92 times 10{sup 11} kcal/year will be available, accounting for approximately 30% of the city's energy consumption. When the energy resources are broken down by type, it is found that solar energy, wind energy, and refuse-derived energy are in existence aplenty. (NEDO)

    For working out and proposing project themes optimum for the popularization of technologies for effectively utilizing energy in four countries in Central Asia (Kazakhstan, Uzbekistan, Turkmenistan, and Azerbaijan), basic surveys were conducted into their energy policies, trends of supply and demand, electric power industry, metal refining industry, and cement making industry. Common to the four nations were that they were rich in energy resources (natural gas, oil, and coal) but that they failed to utilize them effectively despite of an increase in the yields. Incomplete infrastructures and delay in the implementation of energy measures attracted attention. A higher priority was found attached to the upgrading of and investment in structures, renewal of facilities, and the intensification of management. The basic industries wanted the modernization of their facilities and processes. As for electric power consumption, Kazakhstan consumed 53.0-billion kWh, Uzbekistan 39.0-billion kWh, Turkmenistan 4.4-billion kWh, and Azerbaijan 16.4-billion kWh. In Uzbekistan, where the nonferrous metal refining industry led its national economy, the energy consumption rate was found to be quite high. There was a decrease in production in the cement making industry. (NEDO)

    For working out and proposing project themes optimum for the popularization of technologies for effectively utilizing energy in Bangladesh, a basic survey was conducted into Bangladeshi energy policy, trend of supply and demand, steelmaking industry, cement making industry, and chemical fertilizer making industry. Bangladesh in fiscal 1997 consumed 10-million tons of energy in terms of oil, 60% or more in natural gas (domestic), 20% in oil, and the remaining 20% in others. Approximately 15% of all the households were supplied with electric power. There was no integrated production plant in the steelmaking industry. Only one mill performed calcination in the cement making industry. The impact to be imposed by the steelmaking and cement making industries on Bangladeshi energy consumption would be small. Fertilizer making was an important industry outputting 2.6-million tons, responsible for 30% of natural gas consumption. The highest priority was given to facility rehabilitation and production enhancement, and there was little hope that energy conservation facilities/technologies would be introduced into the steelmaking and fertilizer making industries. It was possible, however, that the horizontal tube mill would be replaced by a vertical roller mill in the cement making industry. (NEDO)

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

    In view of relatively good solar radiation that the prefecture enjoys and of a result of the investigations of this time conducted into the amount of new energy in existence, it is concluded that a fairly large amount of solar energy is collectable as the regional new energy for Gunma Prefecture. As for wind power energy, since there is no proper location in the prefecture where the annual wind speed average of not less than 5m/s is available, the value generally accepted as necessary for wind power generation, it is inferred that conditions in the prefecture in general are disadvantageous when it comes to wind power generation. As for hydraulic energy of small and medium dimensions, a result of the investigations shows that in the prefecture this energy is next to solar energy in terms of the amount expected to be collectable. In this prefecture, the prefectural project bureau makes use of the rich water resources and generates electric power, and supplied approximately 850-million kWh in fiscal 1998. Since it is feared that it will be difficult to find new sites for power generation in the area now remaining to be developed, however, prudence should be exercised in estimating the expected collectable amount of hydraulic energy.

    The purpose of the survey is to promote the international research cooperation projects from the survey stage, via demonstration research stage to the diffusion stage. Field surveys have been conducted to find out the needs of energy saving and environmental technology for the efficient consumption of petroleum in the developing countries with mass-consumption of petroleum in the future. The survey was conducted in the Philippines in the FY 1996. Next developing themes were proposed. The first theme was developing method of sugar plant. The magnesia method has been developed as a basic technology for cleaning sugar solution process instead of using lime. By the recycling method, the waste cake amount can be remarkably reduced. The second theme was electron beam exhaust gas treatment by a dry method of simultaneous desulfurization and denitrification of high concentration SOx and NOx in the fertilizer production plants. The third theme was the energy saving technology for SOx reduction of heating furnace for iron-steel by using an ultra energy saving-type regenerative burner. The last theme was chlorine bypass technology in cement industry, which would become an advanced technology development for the use of chlorine containing fuels in the near future. 40 refs., 36 figs., 79 tabs.

    Field research was made for oil saving in Thailand. To promote energy saving in a textile industry as main export industry, its motivation for production stuff is essential in business improvement. Proposal for work improvement, supply system of bonuses, and small-group activity are effective. Management of an energy consumption rate is essential in business management. Use of efficient waste water treatment equipment is also one of the issues. In food factories, various scopes for improvement are still found by mass/heat balance analysis in production process. As an example, a large amount of water is consumed in vain for washing raw rice in a rice powder factory, and separation of SS precipitate from waste water should be improved. Because of lagoon treatment, an effluent standard is not achieved in spite of consumption of wasteful aeration power. This treatment is reasonable because of its scale and site, although the standard can be achieved by activated sludge method. Reconsideration of the standard is also necessary based on a local total BOD load capacity. The profitability of a methane fermentation method should be examined. 72 figs., 95 tabs.

    The field research of oil conservation was conducted in developing countries, in particular, Vietnam where a steep increase in oil consumption is anticipated in the future. Energy conservation is the most effective direct measures to control combustion of fossil fuels, and an important issue to be promoted by all countries in the world to prevent global warming and reserve energy resources. In fiscal 1994, main industries in the northern part of Vietnam were researched. In fiscal 1995, the report meeting of plant survey results in the northern part and the technical seminar of energy-saving in industrial field were held, and plants around Ho Chi Minh City in the southern part of Vietnam were researched. Although Vietnam has recently acquired membership in ASEAN and is undergoing dramatic economic growth, has many problems in environmental measures. Japan has top-ranking results on energy-saving in industrial field, and the transfer of such superior technologies and techniques will greatly contribute to resource and global warming problems as well as pollution control measures in Vietnam. 13 refs., 25 figs., 26 tabs.

    A sharp rise in industrial productivity in Asia countries indicates a rising level of R and D technology. Since Japan has not clearly grasped the R and D ability in these countries, it has not given appropriate personnel/material R and D support to them. Therefore, for the purpose of exactly grasping the R and D ability of Asian countries (Korea, Taiwan, the Philippines, Indonesia and India) and studying an effective and appropriate method for R and D cooperation, a survey was conducted of R and D potentials in Asia and R and D support policies of the countries. As a result of the survey, the following are taken up as items to be considered: promotion of exchanges between Tsukuba, etc. in Japan and research/university towns and science parks being constructed in lots of countries, participation of private companies in high-tech joint work in cooperation with Japan, sending information from Japan using internet, etc. and exact grasp of needs at partner side, cooperation given to new comers without asking for research results (use of OB researchers, etc.) 25 refs., 39 figs., 59 tabs.

    This survey was conducted to construct the core of intelligent social infrastructure technology (ISIT), and to investigate its practical application to industries and society. For realizing the ultra-safe and ultra-reliable society, it is necessary to develop the ISIT which can integrate various social infrastructures, such as architecture, city, energy, and lifeline systems required for living. For the systematization of cities, it is necessary to process and control the intelligent information by holding integrated and transverse information in common, as to logistics, lifeline, communication, monitoring, and control. For the communication engineering, the centralized systems are acceleratingly to be converted into the distributed network systems.

    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.

    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)

    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.

    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.

    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.

    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)

    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)

    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.

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

    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.

    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.

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

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

    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 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 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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

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)

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

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

    History of technological activities of Japanese industry has been recorded, preserved, compiled and systematized. The purpose is to make international contribution by transmitting Japanese experience and knowledge to the world, and to bring up the human resource for researches by teaching the history of passion and efforts of the predecessors and by arousing interests and creative volitions of science and technology of young persons. However, memorial matters, data and witnesses relating to the history of industrial science and technology are rapidly being lost day by day. When leaving as it is, succession of the history to next generation becomes hard. Under such a situation, basic survey has been conducted to succeed the history of industrial science and technology and promote the creative utilization of them. This is in the third stage of the survey. This report contains the development of new cold rolled steel sheet for cars, plant engineering technology in Mitsubishi Heavy Industries, electronics, electric power distribution technology in Kansai Electric Power Co., Inc., development of the PAN carbon fibers, four cycle and low speed marine diesel engines, production of electrolytic copper foil, development of jet engines, camera makers, and production of office machinery. 86 refs., 12 figs., 9 tabs.

    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.

    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.

    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.

    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.

    The number of constructed prestressed concrete cable stayed bridges reached nearly 100 in Japan, and the technique has greatly developed. In this article, the current status of design techniques for prestressed concrete cable stayed bridges were introduced along with the examples of constructed bridges for the analysis method and the design method for each structure part while introducing the current examples of constructed bridges. Also, this kind of extra-dosed prestressed concrete bridge and prestressed concrete bridge with prestressed concrete stays were reported. Standards have been prepared including a chapter for the prestressed concrete cable stayed bridges in the Road Bridge Guideline document in February 1990. Load to be noticed as the characteristics peculiar to the prestressed concrete cable stayed bridges includes the shock due to live load, temperature change, and execution error of a tower. For example, 1/1000 of the total tower height is generally considered as the execution error of the tower. A diagonal member is manufactured at factories and in fields and has both advantages and disadvantages. The linear analysis of plane framework is general. Damping of and earthquakeproof designs against the wind and earthquake of the diagonal member were also provided. 11 refs., 17 figs., 2 tabs.

    For human engineering and improvement of the living environment, the evaluation technology of human behavior cognition was studied. For the future reformation and creation of economic structure, the following are required: establishment of safe and affluent communities, further improvement of the safety and harmonious balance of people, lives and society, and R & D close to people and social needs. Introduction of Product Liability law and a fail-safe concept are examples of such efforts. However, since many accidents are found in the human society, the relation between human errors and human characteristics should be studied in detail. The cognitive science of human behavior is an objective evaluation technology from the viewpoint of human being, object, environment and society. Based on these social and technological background, the feasibility of the evaluation technology is studied, and the future trend and skeleton of this project are clarified. The domestic and foreign trends of technologies concerned are thus surveyed, and the important points, features, skeleton and ripple effect of the technology are summarized. 500 refs., 70 figs., 5 tabs.

    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.

    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)

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

    This survey was made to obtain the basic data for future spread and promotion of No.6 type (waste use type production facilities) and No.7 type (waste fuel production facilities) which were added to the objects having been subsidized since fiscal 1997 under `the environmental harmony type energy community project.` In the former, the kiln in the cement industry and the blast furnace in the steel industry can be extremely large places to receive waste plastic since the facilities are distributed in every area and the treatment capacity is large. However, the effective collection, transportation and sorting of large quantity of waste plastic, especially the problem of removal of vinyl chloride, is a big bottleneck. As to the use of waste plastic using gasification technology, there are no actual results on the commercial basis. That is, however, appropriate for treatment of the waste difficult in treatment, and can be expected of the usage in the chemical industry. In the latter, in the facilities using industrial waste raw materials as fuel, solidification and liquefaction are both operated on a commercial basis. In relation to the solidification and use as fuel of general waste, the treatment of combustion ash is preventing the expansion of use of waste in the industrial field because of a large quantity of chlorine included in the products. 92 refs., 54 figs., 35 tabs.

    With an objective of saving energy and reducing greenhouse gas emission, a basic survey has been performed on the atmospheric crude oil distillation units and the high vacuum distillation units at Cilacap Refinery in Indonesia. The first site survey in September 2000 has carried out a survey on the situation of the facilities and operation upon obtaining the facility data and operation information from Pertamina. As a result, it was revealed that there is a room of improvement in the heat recovery, whereas a modification design was executed on the improvement proposals on the heat exchanger system. However, the second site survey in November 2000 has revealed that Pertamina had executed in 1998 through 1999 the de-bottlenecking project on the crude oil atmospheric distillation units (two units) and the high vacuum distillation units (two units), by which the capability has been expanded, and the heat recovery rate has been increased. It is not possible to look for extremely large enhancement of the heat recovery rate beyond that point, and the reduction of CO2 emission would also be small. As a result of discussions, the present project was found capable of reducing annually the CO2 emission by 36,500 tons. (NEDO)

    The paper described the present situation of the waste treatment system for the environmental engineering and the problems. The final waste treatment plants are in the tighter and tighter condition, and therefore the waste treatment system ought to be changed to a system in which importance is placed on the size reduction, weight reduction, and recycle. Accordingly, the waste treatment system becomes more characterized as a resource feedback process, and should be given more credit as a system for production of secondary resource. The problem is arrangement of conditions of technology, cost and legislation system for smoothing such recycling flow. Of course, it is natural that the most important subject of the system is to secure the environmental preservation by the waste treatment. As future subjects, needed are understanding of the waste treatment as a resource reproductive system, relation with other industries, and review of the legislation system. In consideration of technology, cost and environmental loads, required are proposal of validity of the recycle level limit and a future image of the system structure, and policies for promoting and supporting the recycle business. 47 figs., 104 tabs.

    Discussions have been given on energy conservation, and reduction in greenhouse gas emission through efficiency improvement at the Uong Bi coal burning power plant in Vietnam. The Uong Bi power plant, which has become using coal of lower quality than the design value, has had incomplete combustion, resulting in increase of unburned components in ash, and decrease of the boiler efficiency to 65 to 70%. Clinker hopper troubles have been occurring frequently, causing plant shutdown at a number of times. The turbine efficiency also shows as very low value as 26 to 27%. The plan has envisaged replacement of combustion parts of the boilers, withdrawal and replacement of the turbine generation systems, new installation of electric dust collectors, modification of the ash treatment system, additional installation of the re-circulation system, new installation of waste water treatment facilities, and modification of the waste water treatment equipment in the plant premises. As a result of the discussions, the annual energy saving quantity was found to be 62,936 tons of crude oil equivalent for the case where only one turbine is renewed, and 93,298 tons for the case where both of the two turbines are renewed. The annual reduction quantity of the greenhouse gas emission was found to be 251,215 tons and 372,402 t-CO2, respectively. (NEDO)

    The peak period of the horizontal/vertical spectral ratio of microtremors was referred to the underground structure for the purpose of finding out if it was possible to estimate the ground structure by use of the peak period of the spectral ratio. The observation was carried in the areas of Morioka City and Hachinohe City using seismographs for measuring east-west, north-south, and up-down motions. As for the relationship between the peak period of the spectral ratio distribution involving 490 observation sites and the known gravity anomalies in the Morioka City area, it was found that the peak period of the spectral ratio tended to be shorter from west toward east while the gravity anomalies were greater from west toward east. Again, as for the relations with the underground geology, the period was longer when the distance to the granite basement was greater, and shorter when smaller. In the Hachinohe City area, relations not only of the first period peak but also of the second period peak to the basement were disclosed, which indicates the possibility that the peak period of the spectral ratio will be used as a means for estimating the basement structure. 2 refs., 8 figs.

    A reflection elastic wave seismic survey was carried out as part of the emergency survey of active faults in relation with the Hyogo-ken Nanbu Earthquake. This paper presents an interim report on the survey covering a wide area with deep structure as the survey object. The paper mentions that processing the survey data has been nearly completed, and is in the stage of making analyses and interpretations of the result of the processing, and that the survey was an attempt of making a unified survey over land areas, shallow sea areas, and seas by setting twelve traverse lines in and around the epicenter region. The paper also introduces briefly what has been found on hypocenters used, vibration receivers, vibration intervals, and CPD intervals, and on shapes of faults, particularly the continuity (the relationship of the Ashiya fault, Koyo fault and Osaka bay fault with the above two faults, branching of the Osaka bay fault, faults between the Wada promontory fault, Awaji Island and the Osaka bay fault, the fault off the east coast at the central part of Awaji Island, the Shichiku fault on the west coast of Awaji Island, and the basement fault). Mention is given also on the basement structure chart of the Osaka bay prepared preliminarily for the purpose of reference. 2 figs.

    Hydrogen absorption by a hydrogen storage (MH storage) is investigated for static characteristics, with a constant current applied to the hydrogen generator, and dynamic characteristics, with a fluctuating current applied to the same simulating actual insolation. In the experiment, alloy temperature (MH temperature) in the storage and a current for the generator are preset, and then automatic measurement is allowed to proceed at 10-second intervals of the differential pressure, hydrogen temperature in the piping, absolute pressure, MH temperature, room temperature, and water tank temperature. It is found as the result of the experiment that absorption performance is improved when the MH storage is cooled; that the mean absorption rate which is 1 without cooling increases to 1.62 at 7degC; that the mean absorption rate changes in proportion to the applied current (introduced hydrogen flow rate); that the rate which is 1 at 32A decreases to 0.53 that at 16A; that the absorption rate is dependent more on the current applied to the storage than the temperature of the heat exchanging medium; and that, even in the presence of fluctuation halfway in the applied current, the total absorption will be equal to a case of constant current application if the total amount of applied current is equal. 2 refs., 7 figs., 5 tabs.

    Under study is the modification of the four antiquated 300MW brown coal-fired power plants of the Ryanzanskaya thermal power station. Under the modification program, the plants will be burning a mixture of 60% coal and 40% natural gas for an increase in efficiency and for a great decrease in greenhouse gas emission. The amount of greenhouse gas emission of 6,858,592 tons/year before the modification will be reduced by 19.4% to 5,532,198 ton/year. The budget for the modification will call for 719,731,700 US dollars. EIRR (economical internal rate of return) is calculated based on the figures provided by the Russian office concerned about the current fuel cost and the current rates for the supply of electricity and heat. It is found that EIRR fluctuates depending on the ruble/dollar exchange rate. Although it does not pay at the current exchange rate, yet, when a US dollar is worth 13.0 rubles, an EIRR of 15% will realize at an availability factor of 70%. The same result is obtained when the availability factor is 80% and a US dollar is worth 14.8 rubles. There is a plan to fire the plants with 100% natural gas in the future. If the plan is implemented, a modification to incorporate gas turbine combined cycle will become feasible. (NEDO)

    With an objective of saving energies and reducing greenhouse gas emission, discussions were given on a modernization plan for the Chhatak cement factory in The People's Republic of Bangladesh. The Chhatak cement factory having a nominal production capability of 267,000 tons a year uses mainly wet-type long kilns of old type, consuming a great amount of natural gas. The present plan has discussed adoption of the Japanese energy saving technologies. The technologies use a vertical roller mill for raw material pulverization, a suspension preheater and a short kiln for clinker sintering, a grate cooler for clinker cooling, and the pre-crushing system. The result of the discussions provided the prospects of reduction in the natural gas consumption at 50%, and reduction of electric power consumption at 16%. This will mean the annual reduction of about 22,000 tons as converted to crude oil. The CO2 reduction amount would reach 51,800 tons a year. The total investment amount would be US$37,327,000. The result of the financial analysis according to the case studies appears severe, wherein reduction of the various expenses is desired possibly by the finance from Japan with generous conditions.(NEDO)

    The plant undergoes a survey for higher energy efficiency, pursuant to the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) protocol. Dry quenching and coal moisture control are investigated for the coke oven; exhaust heat recovery and high efficiency ignition burner for the sintering machine; top pressure recovery power generation and hot stove exhaust heat recovery for blast furnace; gas recovery for the converter; scrap preheating for the electric furnace; continuous casting and soaking pit efficiency improvement for the blooming process; hot charge and heating furnace efficiency improvement for the hot strip mill reheating furnace; and furnace efficiency improvement and hydrogen annealing applicability for the annealing furnace. The energy saving effects of the above are calculated under conditions that one more of the same be added to the continuous slab casting unit and that a continuous bloom casting unit be constructed for the continuous casting of the whole, and that hydrogen annealing be adopted. A reduction of 141,900toe/year is to be achieved, which occupies 6% of the energy consumption of the whole steelworks. A greenhouse gas reduction of 333,600t-CO2/year is feasible. Now that privatization is under way for business reconstruction and rationalization, suggestions will be presented in consideration of the order of priority of investment recovery effects with attention paid to the privation program.

    The Back Ho oilfield is the largest oilfield in Vietnam and at the same time is producing the largest amount of natural gas (associated gas) in Vietnam. Although the majority of the associated gas has been used in the power generation plant, a large amount of surplus gas is not effectively used because of shortage of fund and technologies. Accordingly, a feasibility study has been executed for a project to compress 20% of the associated gas into CNG, and use it effectively as automobile and factory fuel. As a result of the site survey, it was found that, although Vietnam consumes less amount of energy and emits less amount of CO2, the nation has a strong interest and a large amount of knowledge about global warming and CDM because the country is subjected to large effect of warming. Furthermore, it has been reconfirmed that introducing CNG into this territory is highly effective. Discussions have been made on places of installing the facilities, effective surplus gas utilization systems, facility specifications, utilities, and number of workers. Calculations were made on approximate cost of the facilities and the running cost. As a result of the surveys and discussions, it was determined that technological support from Japan and the Yen loan for environment with low interest rate are necessary. (NEDO)

    As a project contributing to reduction in greenhouse effect gas emissions by introducing energy conservation technology of Japan to India and to sustainable economic development in India, study of 'conversion of raw materials in fertilizer plants in India' was made, and the results were reported. The Indian government has been controlling the retail price of fertilizer by the subsidy policy for the protection of the domestic fertilizer production. Therefore, plants, which use coal/heavy oil/naphtha with much greenhouse gas emission as raw materials, have been behind improvement and now have no competitive force in the international market. In this project, concerning ZIL's fertilizer plant, the ammonia production capacity was set at 750 t/d and the urea production capacity at 1,300 t/d, and the energy conservation technology and the conversion of raw materials from naphtha to natural gas were studied. As a result, the amount of energy conservation was 55,705 toe/y, and the amount of CO2 reduction was 245,139 t-CO2/y. Further, this project indicated that profits were expected to increase and the cash flow would change for the better. (NEDO)

    The paper reported the FY 1992 basic survey for the coal mine development/industrialization in the Embalut West area of Indonesia. The geological structure in the survey area is under the Loa Haur Syncline which lies approximately north and south to the west of the area, and is regarded as the stabilized structure having no faults. The three beams from the upper part, S14, S13 and S12, are assumed to be the coal seams to be drilled. The average seam thickness is 1.17, 2.35 and 3.09m, respectively, and the continuity is good. In S14 beam, which is thin, it is difficult to mine coal using equipment. The theoretical minable reserve of the three coal seams is 18,859,000 tons. The recoverable coal reserve is 12,258,000 tons at a mining recovery of 65%. In case of annual production of 0.4 million tons, it is possible to mine more than 30 years. The coal is classified into a subbituminous coal-brown coal rank of the JIS coal classification. It is high in water content and medium in heating value, but is an environmental protection type with low ash and low sulfur content. In the case of mines in the Mahakam River basin, barge transport is indispensable. For sea transportation, the following should be studied in the light of the international price competition: reinforcement of shipping facilities on Mahakam River, increase in barge size, joint use of Balikpapan Coal Center, etc. (NEDO)

    This project aims to carry out the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) protocol. In the clinker calcination sector, the wet kiln will be replaced by a dry NSP (new suspension preheater) kiln, and the existing four lines of material manufacturing facility and of clinker calcination facilities will be converted into single lines, respectively. Skills of the highest level will be applied to each of the facilities. The dry process will be dispensed with thanks to the dry kiln, which leads to drastic energy efficiency improvement. The change from ball mills to roller mills reduces electric power consumption. Energy reduction is expected to be 48,554 tons/year in oil at a saving rate of 39%. Greenhouse gas reduction is expected to be 216,960 tons/year in CO2 at a reduction rate of 28.5%. Provided that the construction cost is 98-million US dollars and the yield is 762-thousand tons, the internal rate of ROI (return on investment) will be 5.7% after tax (fully self-financed). ROE (return on equity) values are calculated under various borrowing conditions, and then it is found that the project will be feasible if a low interest loan with a long term of repayment is available. Since all the cement mills are obsolescent in the republic, the conversion of the present kilns into NSP type kilns will gain public favor. (NEDO)

    Petropavlovsk-Kamchatky (P-K) city in Kamchatka, Russia is operating hot-water district heating using heavy oil boilers and waste hot water of thermal power plants as heat sources. Feasibility study was made on district heating using natural geothermal hot water and/or geothermal heat pump systems as heat sources of hot water supply for reduction of greenhouse effect gas emission. Among 3 areas including geothermal hot water, use of hot water in K area was impossible because of lower temperature and less spring water. Use of hot water in P and UP areas was impossible as primary hot water because of temperature drop to 64 degrees C during hot water supply toward P-K city. The building heating operation test was carried out using the geothermal heat pump system installed in a newly drilled heat exchange well of 100m deep. As a result, sufficient heat recovery was achieved for heating. If all of 49 boiler houses for heating are replaced with such geothermal heat pump systems, CO{sub 2} reduction was estimated to be 520,000t/y. (NEDO)

    Commercialization survey was performed on the mines in the Manguerra district in the Philippines by means of geological structure surveys. The site surveys included geological and test drilling surveys, and those on conditions for developing underground mining mines, and infrastructures. The geological survey area spread out about 5 km{sup 2}, two test wells were drilled (to depths of 330 m and 290 m), trench survey was performed on 58 locations, and coal sample collection and analysis were carried out on eight locations. Furthermore, surveys were extended to the Manguerra mine operating status, on-the-ground facilities, roads for transportation, marketing, and related laws and regulations. As a result of the surveys, the Manguerra district was suggested of frequent sea water inundation into the coal field, leading to a view that the district is unstable from the viewpoint of development of coal beds. However, samples collected from the existing mining area indicated to have less water content and ash and high calorific power. The coal has high product value. The result of coal quantity calculation indicated 320122 tons as the total of defined and estimated quantity. The great depth mining plan was prepared from the viewpoints of actual yield, productivity, safety aspects, technological enhancement, and suppression of additional investments to minimum. (NEDO)

    With an objective of saving energy and reducing greenhouse gas emission, a modernization project has been discussed on the North Bangkok heavy oil burning thermal power plant owned by Electricity Generating Authority of Thailand (EGAT). The present project plans to withdraw the existing units No. 1, 2 and 3, and install two new generating facilities with the rated output of 358.3 MW using natural gas as fuel. The present feasibility survey has performed detailed comparative discussions on four cases, whereas a proposal was selected to withdraw all of the boilers, steam turbines, and generators, and install two single axis combined cycle systems whose output has been increased by using the existing fuel tank area. The energy saving effect by this project can reduce fuel consumption annually by 514 kt of crude oil equivalent. The greenhouse gas can be reduced annually by 2,680 kt-CO2. The project will require a total fund of about 57 billion yen. The profitability assessment calls for the internal profitability of 8.413% and the investment fund efficiency of 1.69%. The economic investment payback effect of this project is determined sufficient. (NEDO)

In order to promote the AIJ Japan program smoothly, some practical examples in every preceding country and the situations and demands of Asian countries were researched. It was confirmed that since larger cost-effectiveness is achieved just in countries lower in emission control cost, AIJ can enhance the cost-effectiveness and promote environmental technology transfer. Japanese government had studied establishment of the framework for AIJ, and decided the basic framework of the AIJ Japan program in 1995. The government also approved the evaluation guidelines of this program which include confirmed and considered matters necessary for government offices related to this program to evaluate and approve each project.

In the quantitative evaluation of the multiplier effect, in the case of making the demonstration of the same technology in the same area both in the model project and the basic survey for promotion of JI, it becomes possible to grasp the CO2 reduction effect with high accuracy, but the CO2 reducible amount is small. Inversely, as to the technology for which the basic survey for promotion of JI is studied, but the model project is not carried out, it becomes possible to grasp the CO2 reduction effect with low accuracy, the CO2 reducible amount is large. In the comparison with the JI/CDM projects proposed in the world, the CO2 reduction amount was approximately $2.7 billion, 250 million tons, in the UNFCCC project, and approximately $5.0 billion, 500 million tons, in the IJ project. There was no very big difference in the cost effect. (NEDO)

    This project was aimed at developing methods for producing basic chemicals from carbon monoxide and other stocks (the so-called C1 chemistry), in order to establish the techniques that could promote stable supply of basic chemicals from the new carbon resources in place of oil. It was a 7-year national project beginning in FY 1980, jointly implemented by the government, academic and industrial circles. Described herein are the overall evaluation of the results. There are several carbon resources other than oil, e.g., coal, natural gas, oil shale and tar sand. They are abundantly occurring, although unevenly, and various countries are developing these resources. They can be advantageously utilized as stocks for chemicals, after being converted into synthesis gases. In Japan, they have been efficiently developed cooperatively by national institutes, enterprises, academic circles and chemical industry, to produce the world's results, e.g., gas separation/purification techniques and new catalysts for new synthesis methods. This project was terminated because of the relaxed oil supply/demand situations and lowered crude prices in the middle of the 80's, which made stock conversion less urgent. (NEDO)

    This paper describes the result in fiscal 1999 of the feasibility study applied with the COP3 clean development mechanism for Bekabad Cement Factory in the Republic of Uzbekistan. One of the existing three old type kilns were diverted and converted into a dry NSP type kiln (having the same production capacity as the present of 726,000 tons a year). This arrangement was intended to enhance the productivity, save the energy, and reduce emission of greenhouse gases and different pollutants by renewing the upper and lower stream facilities and installing such environmental devices as electric dust collectors and bag filters. The total construction cost is US$84,432,000. Reducible energy consumption and reduction quantity of greenhouse gases would be 73,232 toe/year and 176,528 toe/year, respectively, in the single fiscal 2006. The cumulative quantity over twenty-year period until 2025 would be 1,464,640 toe and 3,530,560 toe, respectively. The energy saving effect per US$1,000 would be 17.87 toe, and the greenhouse gas reduction effect would be 43.08 t. In the case of using a soft loan such as the special yen loan for environment application, the internal profit rate after tax would be 7.63%, which is not high as the business enterprise profitability. However, the profit and loss statement indicates creation of profit after two years of operation, hence there is a relative realization possibility. (NEDO)

    On the basis of Kyoto Protocol-provided flexible measures such as joint implementation and clean development mechanisms, a study is conducted for introducing combined cycle into Konakovo Power Plant of Russia currently equipped with antiquated eight 300MW power plants constructed in the 1960's for which early renovation is necessary. The power station is an important power source connecting to the Moscow-Petersburg main. The gas turbine combined facilities to be newly installed will comprise 250MW-class state-of-the-art gas turbines arranged in four blocks, capable of a total output of 1600MW at a thermal efficiency of 58% (with simultaneous supply of heat). Four units capable of 1200MW out of the existing units will stay in operation for load adjusting. Since the price of power is set low under government control, the accounting capital/internal return rate is as low as 2.3%. The rate recalculated under the financing conditions of special yen credit for environmental protection, however, is as high as 19%, so high as to make the renovation an economically feasible project. It is expected that there will be an annual CO2 reduction of 2.3-million tons or a reduction of 57.50-million tons in 25 years (the life span of the new facilities). The renovation may be a joint implementation project to which both Japan and Russia will attach the highest priority. (NEDO)

    This effort complies with the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) joint implementation clause. The plan is to replace the existing old facilities with three units of 107MW rated single shaft combined cycle power plants. Each unit comprises one 70MW rated gas turbine generator, one water circulating reheat type steam turbine/air cooled synchronous generator, and one exhaust heat recovery boiler. The rated output will be 321MW in total, and the maximum heat supply 71Gcal/hour. Fuel consumption will be less by 304,800 tons/year in terms of oil at a reduction rate of 46.3%. Greenhouse gas will be less by 712,089 tons/year in terms of CO2 at a reduction rate of 46.3%. The modification will cost 224-million US dollars. To secure profitability under the project and to keep EIRR (economic internal rate return) at 15% or higher, CO2 has to sell at 13 US dollars/ton in terms of CO2 or a US dollar has to be equivalent to or less than 4.9 UAHs (with repayment to be made in US dollars). Profitability will vary extensively, dependent on fluctuations in the exchange rate reflecting the Ukrainian economic state and on the magnitude of greenhouse gas trading scheme. (NEDO)

    With objectives of saving energy and reducing greenhouse gas emission at the Pridneprovskaya power plant in Ukraine, a scrap and build project has been discussed. This project will abolish the unit No.12 among the eight units in the existing coal burning power generation facilities, and install a natural gas burning combined cycle plant comprising of three units each with an output of 100 MW. The new plant facilities will consist of gas turbines, steam turbines, HRSG and auxiliary devices, and an air-cooled synchronous power generator with a capacity of 119 MVA. Use of natural gas as fuel reduces generation of soot, sulfur oxides, nitrogen oxides, and CO. In addition, the hot effluent and waste liquor effluent will decrease from those at the present plant. The required fund will be 30,107 million yen. The energy saving effect of this project is reduction of about 7.5 million tons of crude oil equivalent as a total in 40 years. The greenhouse effect gas will decrease by about 39 million tons as a total in 40 years. The profitability estimation calls for the number of investment recovery year of 16 years, and internal profit rate of 7.32%, wherein the implementation of the project cannot be expected as a project to be carried out by private funds.

    Costa Rica takes a power generation system using hydro power generation as the main source, and possesses medium-capacity gas turbines to supplement needs in the dry season and the peak load. However, a problem has come up that, in addition to the cost rise in gas turbine fuel, the power generation efficiency has been aggravating due to aged deterioration of the generators being used. In association therewith, the problem is now a factor to increase CO2 emission, which is a worldwide problem. Keeping in mind to link it to the clean development mechanism (CDM), the present project is, taking up the SAN ANTONIO power plant as the investigation object, intended to perform a comprehensive discussion on the CO2 emission reducing effect, profitability, and proliferation effect, by executing the conceptual plant design. The up-grading plan for thermal power generation systems in Costa Rica consists of replacement of the gas turbines, handling of phase modifiers, and achievement of the combined cycle. The plan agrees with the present feasibility study intended of CO2 emission reduction, consisting of the modification plan of the SAN ANTONIO power plant, that is the plan to replace the over-aged gas turbines at the power plant. Its necessity has been identified. It was disclosed that the project has the effects of reducing CO2 of 82,000 tons annually, and the investment can be recovered in nine years. (NEDO)

    This project was aimed at developing methods for producing basic chemicals from carbon monoxide and other stocks (the so-called C1 chemistry), in order to establish the techniques that could promote stable supply of basic chemicals from the new carbon resources in place of oil. It was a 7-year national project beginning in FY 1980, jointly implemented by the government, academic and industrial circles. Described herein are the overall evaluation of the results. There are several carbon resources other than oil, e.g., coal, natural gas, oil shale and tar sand. They are abundantly occurring, although unevenly, and various countries are developing these resources. They can be advantageously utilized as stocks for chemicals, after being converted into synthesis gases. In Japan, they have been efficiently developed cooperatively by national institutes, enterprises, academic circles and chemical industry, to produce the world's results, e.g., gas separation/purification techniques and new catalysts for new synthesis methods. This project was terminated because of the relaxed oil supply/demand situations and lowered crude prices in the middle of the 80's, which made stock conversion less urgent. (NEDO)

    This project is a feasibility study to get effects of reducing greenhouse effect gas by repairing Units 8, 9, and 10 (330MW in total) of Schekinskaya thermal power plant and Units 1-7 (450MW in total) of Novomoskovskaya thermal power plant. Both are very old brown coal fired thermal power plants which were constructed during 1947-1967. At present, they are run fired by natural gas. Being very superannuated, they need repair of the facilities. In the adjustment of opinions with Russia, the plan was aimed at substantial reduction of greenhouse effect gas by increasing thermal efficiency of power plant. For it, a 800MW class gas turbine combined cycle power plant is constructed at Novomoskovskaya power plant where there are existing buildings and space for equipment and where gas fuel can be used. As a result of the study, it was indicated that the reduction amount of greenhouse effect gas after the repair becomes 1,853,966 tons/yr as against 3,590,514 tons/yr before the repair. (NEDO)

    The feasibility study was started upon a request made by the Iranian Ministry of Energy involving the No. 7 kiln of the above said company. It was then concluded, after assessing the degree of urgency of supply and demand and the magnitude of loss due to reduced production because of the on-site modification work, that it was not practical to begin the project immediately. Under the circumstances, various studies were made about the feasibility of modification of the whole production process of the No. 1 kiln through No. 7 kiln, and a procedure was presented, to be described below. The procedure will consist of Phase I wherein the No. 3 wet kiln is converted into an NSP (new suspension preheater) dry kiln, Phase II wherein the No. 7 SP (suspension preheater) dry kiln is converted in to an NSP kiln, and Phase III wherein the No. 4 SP dry kiln is converted into a clinker cooler. Under this procedure, the modernization of the Tehran Cement Co., Ltd., facilities will be accomplished without causing production loss. After the completion of the project, an annual yield of 3.6-million tons will be achieved, with productivity to be improved by 26.4% over the current theoretical capacity or by 54.8% over the actual average for the past 5 years. There will be a sustained conservation of 25,356 tons/year in terms of oil. Application of CDM (clean development mechanism) to this project will be extremely effective in reducing greenhouse gas and in improving profitability. (NEDO)

    A fundamental coal mine development investigation was carried out in Batulicin Area, Kalimantan, the Republic of Indonesia. The investigation included ground surface surveys, preparation of topographical maps and geological maps, trial drilling investigation, physical logging, chemical analysis, and infrastructure investigation. The trial drilling investigation was intended to identify the existence conditions of coal beds and coal quality, and was performed by forming grids with about 500-meter interval, and using 21 trial drillings to depths of 104 to 240 meters for a total drilling length of 3463 meters. The physical logging included electric logging, radioactivity logging and pore size logging, and the trial drilling cores were subjected to chemical analysis. For infrastructures, investigations were carried out on necessity of modifying existing roads, privilege relationship, the current status of barge loading points, water depths, and land acquisition. The result of the investigation revealed that minable coal quantity in underground mining of the coal bed B would be 13.189 million tons, and that annual production of original coal at 733,000 tons would be possible by adopting a long-wall type mechanized coal mining system. 14 refs., 99 figs., 25 tabs.

    Discussions were given on the modification plan for Khabarovsk Thermal Power Plant as part of the basic survey on promotion of joint project implementation based on the COP3. The plan calls for shutting down the overaged power plant No. 1 (462.5 MW) and newly building the power plant No. 4 with high efficiency to reduce CO2 emission. The plant will use coal, which is mined extensively in the region. The plant will be a combined heat and power plant with a total power generation output of 576 MW and a total thermal output of 1140 Gcal/h. Effect of reducing CO2 emission as the result of this modification plan will be as much as about 1.2 million tons annually. The plant will use coal as fuel in the beginning, but if it uses natural gas in the future, for which pipeline construction from Sakhalin has been planned recently, the CO2 emission reducing effect will reach 2.4 million tons. Internal profitability was calculated with the CO2 price set at zero US dollars and with the foreign exchange rate varied, for a case of firing coal for 30 years. The profitability may vary largely according to the foreign exchange level, such as profit rate of 5.47% at 20 roubles to a US dollar, 11.04% at 12 roubles, and 21.22% at 6 roubles. The profitability should be judged somewhat low under the current exchange rate of 20 roubles to a dollar. Financial provision with a favorable condition is strongly desired. (NEDO)

    Inter-industry relations tables and energy statistics are combined for Asian countries for the preparation of energy analysis oriented inter-industry relations tables, which are used to metrically analyze Aisan nations' industrial structures and energy consumption structures for the ultimate purpose of grasping the magnitude of each industry's demand for energy. The tables prepared this year cover Korea, Indonesia, Thailand, and the Philippines. In Korea, the self-sufficiency rate of mineral fuels is low at 23.1%, which is due to its import of crude oil from abroad. It consumes 177.92-million tons (in terms of oil) of energy for its economic activities, with energy saving measures expected to work effectively here. Indonesia's mineral fuel self-sufficiency rate is high at 84.3% because it is an oil producing country. The energy it consumes for its economic activities is 179.37-million tons (in terms of oil), and energy saving measures will work effectively here. Thailand is a crude oil importing country. Its mineral fuel self-sufficiency rate is 33.4% and the energy its economic activities consume is 53.08-million tons (in terms of oil), and energy saving measures will work effectively in this country. The Philippines is a crude oil importing country and its mineral fuel self-sufficiency rate is as low as 4.8%. It consumes 22.71-million tons of energy (in terms of oil) for its economic activities, and energy-saving measures are expected to take effect here. (NEDO)

    Investigations and discussions have been given on measures to improve energy conservation and efficiency at a power plant of Kish Water and Power Company (KWPC) in Iran. The site has high ambient temperature throughout a year, making the gas turbine power plant capable of generating power only at about 70% of the rated output, with the power generation efficiency decreasing. The project has analyzed the current situation at the plant, and evaluated different means that appear effective in improving the efficiency, including the gas turbine absorbed air cooling system, the steam injection system, and the combined cycle. As a result of the discussions, it was revealed that energy saving effect can be obtained at 145 TJ with the gas turbine absorbed air cooling system, 224 TJ with the steam injection system, and 1017 TJ with the combined cycle. The annual reduction of greenhouse gas emission due to the above energy conservation would be about 11 thousand tons, 16.5 thousand tons, and 75 thousand tons, respectively. However, the investment payback period would be about 2.45 years, 8.31 years, and 14.21 years, respectively. Therefore, the profitability does not appear very attractive because of low fuel unit cost. (NEDO)

    For the purpose of conserving energy and reducing greenhouse effect gas emission, survey was conducted for the repair plan for Fenchugangi fertilizer plant in Bangladesh. In the survey, studied were measures to increase production, measures to prolong the plant life, energy conservation measures and environmental measures. As a result of the study, it was confirmed that if the production amount targeted at first is recovered and the consumption amount of natural gas can be reduced down to the original target by rehabilitating the superannuated equipment/machines and by supplying/preparing the spare parts in shortage, the reduction in greenhouse effect gas emission is achieved and the production cost of urea fertilizer is lowered. Further, it was found that by carrying out this, energy efficiency can be heightened at the parts which can be replaced with the newest processes. The energy conservation amount calculated was 25,890 toe/y, and the amount of greenhouse effect gas reduction 60,448 t-CO2/y. The investment amount was approximately $19,106,000. The total interest is to be raised by soft loan, and the internal earning rate was 9.04% with the present prices of natural gas and urea. (NEDO)

    Discussions were given on conversion of shaft kilns mainly used at Tianjin Cement and Huaxin Cement to the fluidized bed cement kiln of the most advanced type. Possibility of energy conservation in China, that is reduction of carbon dioxide emission, was evaluated. This system has been developed by the Center for Coal Utilization, Japan. The system is characterized by reduction of greenhouse effect gas emission, elimination of the problem of dust scattering from sintering facilities, stabilized production of high-quality clinker, capability of using low-grade coal and anthracite, and reduction of cement production cost. As a result of the discussions, the reduction rate of greenhouse effect gases was found about 17 to 33%. The cost effect may be calculated as 2 to 5 thousand yen per ton of CO2 reduction amount assuming the system life of 20 years. If this process has been diffused into China, the quantity of CO2 to be reduced will reach about four million tons annually assuming a diffusion rate of 10%. This project shows as high profitability as about 20% at IRR, and the system is more advantageous economically than the shaft kiln. (NEDO)

    The storage tank is classified into a mixed type and stratified type. The stratified type is judged to be more advantageous from a viewpoint of the effective energy utilization. An experiment was made using a solar simulator to put the system, consisting of a vacuum double-glass tube collector and temperature selective storage tank, to practical use. The ejection position of the storage tank at the top is superior to that at the bottom, in the 60{degree}C layer of three layers (60, 40, and 20{degree}C). The ejection position hardly varies with the shape (straight or elbow) of an ejection port. When the temperature stratified layer is formed in two layers (40 {times} 2, 20{degree}C) to three layers (60, 40, and 20{degree}C), heat can be stably stored as the flow rate is higher. The stratified storage tank is inferior to the mixed storage tank in heat collection efficiency, but the specific exergy increases. By increasing the number of heat storage layers, the result of this experiment can also be applied to the linear temperature gradient layer obtained in the practical use. As a result of the above experiment, the basic data for an automated system design during practical application was obtained. 3 refs., 15 figs.

    An investigational study was conducted of a project for energy conservation and greenhouse effect gas reduction by introducing the steam injection gas turbine generator to production facilities of the Siam Cement Industry Corporation (SCI) in Thailand. In the project, studies were made on the following: no purchases of electric power by introduction of the steam injection gas turbine generator; additional heating by gas turbine exhaust gas by introduction of the kiln combustion air heater; remodeling of the preheater of raw materials, and the partial calcination before kiln sintering by introduction of the calcination furnace. As a result of the study, the energy conservation amount was 1,200 toe/y, and the greenhouse effect gas reduction amount was approximately 8,000 t-CO2/y, which led to the reserve power for increased production of clinker by about 18%. The size of investment was 314.5 million Baht in total. As to the evaluation of economical efficiency of the investment, the actual period of ROI was a little less than 5 years, and the internal earning rate was 17.7%, which substantially met with SCI's standards for equipment investment. However, there are problems on the gas supply infrastructure, recovery of the white cement demand, etc. (NEDO)

    To establish the inhomogeneous solid combustion control technology, effects of the strong magnetic field on the solid combustion were examined. When applying the sufficiently strong magnetic field, it is possible to control the air flow in combustion field by utilizing the force applying to constituent oxygen with large susceptibility. Based on this possibility, combustion experiments of expanded polystyrene plates were conducted between the magnetic poles of electro-magnet having the maximum flux density of 1 T and the maximum magnetic field gradient of 0.5 T/cm. To observe the effects of magnetic field without the effects of natural convection, combustion experiments of acrylic sheets were conducted between the magnetic poles of electro-magnet having the maximum flux density of 0.6 T and the magnetic field gradient of about 0.1 T/cm under the microgravity conditions between 10{sup -4} and 10{sup -5}g using a microgravity test facility. Consequently, prospective combustion results could be obtained, in which the force of flame received from the magnetic field is almost equivalent to the buoyancy of flame. It was demonstrated that combustion can be controlled by the magnetic field. 1 ref., 3 figs., 1 tab.

    Commercialization survey was performed on the coal beds in the Kalewa area in the Union of Myanmar by means of geological structure surveys. The site surveys included on-the-ground survey, test drilling survey, sample collection and analysis, and infrastructure survey. The on-the-ground survey area spread out about 5.5 km{sup 2}, wherein nine test wells were drilled (for total distance of 2,046.74 m), and coal and rock sample collection and analysis were carried out on six samples. The infrastructure survey was performed on coal transporting roads, and barge loading planned points and facilities. As a result of the test drilling survey, existence of coal beds with thickness of 4 ft, 9 ft and 6ft was identified. Since the 9-ft bed in particular exists stably with inclination of 40 to 42 degrees over the whole subject area, it was made clear that the bed can be the object of mining as the main coal bed. The coal is the ordinary coal with such good qualities as ash content of 4.72%, total sulfur content of 0.22%, and total calorific power of 6,500 to 6,570 kcal/kg. The defined coal quantity for the 9-ft bed is four million tons, or 7.7 million tons in total if the estimated coal quantity is added. The quantity will amount to 15.3 million tons when those of the 4-ft and 6-ft beds are added. (NEDO)

    This paper describes an algorithm for calculating the equilibrium state of carbonate system in seawater. The photo-synthesis, respiration, and basic production ability of organic and inorganic carbon compounds by calcification of coral reef ecosystem and the change in carbonate system in seawater were discussed. The carbonate system in seawater can be estimated by determining two variables among the four variables, i.e., pH value, total carbonate, total alkalinity, and partial pressure of carbon dioxide (PCO2). The analysis program proved to give good agreement with the previously calculated results. In the inorganic production of carbonate in seawater, one mole of carbonate precipitation liberates approximately 0.6 mole of CO2 into the air, and the pH value shifts toward acid side. The experimental value (0.55) for production speed ratio of inorganic carbon to organic carbon in the seawater where the coral family is abundant brings about the increase of the organic carbon production, resulting in the decrease in PCO2 in seawater and the increase in pH value. It is assumed that it becomes of a sink of CO2 in the atmosphere. 23 refs., 3 figs., 7 tabs.

    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.

    The project aims to establish basic technologies for the mass culture of cells which will enable a large, stable supply of fine chemical products whose industrial production the conventional technique of synthesis has failed to realize. In the 1st phase, cell stains were selected, a serumless medium was developed, basic culturing conditions were established, and substances production rates were improved, and the 2nd phase stands succeeding these 1st phase achievements. Toward the ultimate goal of establishing basic technologies for serumless high-density cultures for industrial use and technologies for isolating and refining useful substances, a small-scale optimum culture technique and a serumless culture technique are developed. Serumless cultures are developed for strains of man's lymphoid cells, cells deriving from bone marrow, epithelial cells, and hybridomas of man and mouse, all these sampled during the 1st phase endeavors. Success is attained in growing each cell strain on a scale of 1-10L to increase to 10{sup 7} cells/ml or more in population density. It is found that each cell strain produces useful substances, such as man's monoclonal antibodies and elements involved in the multiplication or differentiation of new cells. (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)

    As to the research on the superconductor manifestation mechanism, Y123 monocrystal which was partially replaced with Zn and Ni was manufactured, and it was made clear that the addition of these impurities greatly change anisotropy of superconductors. It was made clear that instability of lattice and magnetism is included in high temperature superconductor. Also made clear was an important role in the Nb/Ba replacement in existence of magnetic flux melting phase transfer and the magnetic field induced pinning effect. The manufacture of Y123 bicrystal membrane was successful by the liquid phase epitaxy method. The manufacture of non-copper base K-Bi-O new superconductor was successful by the ultra-high pressure synthesis method. The stabilized process was established for large size crystals of 15-20mm square in Y base and of 20-25mm square in Nd base.

    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)

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

    The project aims to establish basic technologies for the mass culture of cells which will enable a large, stable supply of fine chemical products whose industrial production the conventional technique of synthesis has failed to realize. In the 1st phase, cell stains were selected, a serumless medium was developed, basic culturing conditions were established, and substances production rates were improved, and the 2nd phase stands succeeding these 1st phase achievements. Toward the ultimate goal of establishing basic technologies for serumless high-density cultures for industrial use and technologies for isolating and refining useful substances, a small-scale optimum culture technique and a serumless culture technique are developed. Serumless cultures are developed for strains of man's lymphoid cells, cells deriving from bone marrow, epithelial cells, and hybridomas of man and mouse, all these sampled during the 1st phase endeavors. Success is attained in growing each cell strain on a scale of 1-10L to increase to 10{sup 7} cells/ml or more in population density. It is found that each cell strain produces useful substances, such as man's monoclonal antibodies and elements involved in the multiplication or differentiation of new cells. (NEDO)

    It needs long time to carve a molding die of bumper, which has a large and deep cavity. To shorten the milling time, we must make the machining more performable and accurate, and develop the new technology of CAM. 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.

    Japan-U.S. comparative research was made on technology transfer and innovative industry support. The U.S. industry is greatly benefited by universities, which is consequently strengthening the international competitiveness of the U.S. economy. However, the partnerships between private firms and universities have no fixed pattern, and keep changing dynamically. Business incubators increased to 627 rapidly, and mainly supported by municipal governments and universities. The U.S. has a well-established mechanism of technology transfer, and has succeeded in many cases. Not only universities but also national laboratories commit to technology transfer to venture businesses, and after starting businesses, entrepreneurs can use various hedging systems which are expected to play a role promoting the future technology innovation. The U.S. also has many advanced areas for sustainable technology innovation, like Silicon Valley, and these areas contain many supporting bodies to help new businesses. The activity of these bodies is very suggestive to Japanese local platforms promoting technology innovation and new local industry creation. Study was also made on the possibility of technology exchanges with overseas advanced areas. (NEDO)

    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.

    Under the hydrogen-utilizing international clean energy system technology project WE-NET (World Energy NET Work) in fiscal 1998, researches and studies were conducted to clearly define safety designs and to improve on accident-and-safety analyses. In relation with system safety design, investigations continued into Japanese and foreign manuals and regulations about the handling of hydrogen and its peripherals, and safe design guidelines (draft) were compiled. Anomalies and accidents supposed to be typical of each of the systems concerned were investigated. As for accident-and-safety analyses, incorporation of a turbulence model was studied in relation to models representing the leak, evaporation, and diffusion of liquid hydrogen, and improvement was achieved when the scope of evaluation was enlarged concerning the hydrogen detonation model. The integration of the two models was discussed for the due evaluation of a series of processes of liquid hydrogen leak, evaporation, diffusion, and detonation. Calculation was performed for two assumed accidents, and the results were found to justify the integration of the two models. (NEDO)

    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.

    Described herein are the results of the FY1994 research program for international joint technology development for solar energy utilization systems. The joint study with an Indonesian research institute takes a model of lumber drying plant for the design and feasibility study. All the parts it needs are technically available in Indonesia, except carbon fiber sheets and electronic devices for controlling purposes. The drying cost is higher than that of a plant which procures charge-free wood fuel, but lower than that of a plant which procures fuel at 30$/t. A cacao drying plant model is also studied. The feasibility study shows that the initial investment for the blowing-up model is much higher by 60% to 100% than that for the conventional plant. Its fuel cost is lower by 11% than that of residual oil but 27% higher than that of wood. 4 figs.

    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.

    Study was made on production technology of the 5th- generation material 'eco-smart composite structure' based on micro-capsule technology. This material ought to have an intelligent function including self-detection and self- restoration of defects, environmental harmony, high strength and long life. At present, these demands are implemented by embedding a sensor, actuator and controller in structure, or optical fiber, shape memory alloy and computer chip in matrix, however, such complex material structure has adverse effect on environment. On the other hand, single structure material such as biodegradable polymer is unusable in severe environment such as the ocean and space. These problems can be resolved by combining composite material and micro-sphere technology, for example fiber-reinforced plastic (FRP) composite structure including micro-capsules with nano particles.

    A survey is conducted into the effects of projects implemented under the large-scale industrial technology research and development system. In the development of 'ultraperformance computers,' each of the technologies is being widely utilized, and the data service system of Nippon Telegraph and Telephone Public Corporation and the large computer (HITAC8800) owe much for their success to the fruits of the development endeavor. In the development of the 'desulfurization technology,' the fruits are in use by Tokyo Electric Power Co., Inc., and Chubu Electric Power Co., Inc., incorporated into their desulfurization systems. Although there is no practical plant based on the 'great-depth remotely controlled submarine oil drilling rig,' yet oceanic technologies and control methods are being utilized in various fields. The 'seawater desalination and by-product utilization' technologies have enabled the establishment of technologies of the top level in the world thanks to the resultant manufacture of concrete evaporator and related technologies. Eleven plants have been completed utilizing the fruits of the development. In the field of 'electric vehicle,' there is no commercialization in progress due to problems in cost effectiveness though remarkable improvement has been achieved in terms of performance. Technologies about weight reduction, semiconductor devices, battery parts and components, etc., are being utilized in many fields. (NEDO)

    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.

    Study was made on production technology of the 5th- generation material 'eco-smart composite structure' based on micro-capsule technology. This material ought to have an intelligent function including self-detection and self- restoration of defects, environmental harmony, high strength and long life. At present, these demands are implemented by embedding a sensor, actuator and controller in structure, or optical fiber, shape memory alloy and computer chip in matrix, however, such complex material structure has adverse effect on environment. On the other hand, single structure material such as biodegradable polymer is unusable in severe environment such as the ocean and space. These problems can be resolved by combining composite material and micro-sphere technology, for example fiber-reinforced plastic (FRP) composite structure including micro-capsules with nano particles. According to targets, this material can have a self-restoration intelligent function, and other environment friendly functions such as easy decomposition, sound insulation, oscillation damping, electromagnetic shielding and hygroscopicity.

    This paper describes the achievements in fiscal 1980 in developing a technology to measure inside of geothermal wells, and of fracturing (to achieve enhancement and regeneration of well performance). Design and fabrication were completed on the in-tunnel sensor for a neutron/density logger. The sensor withstood use at a temperature as high as 275 degrees C. In logging and reservoir evaluation field tests, reliable data were derived even at a depth of 1,800 m and a temperature of 250 degrees C. Characteristics of response of radioactivity logging (neutron and density logging) to different igneous rocks were investigated by using rock blocks. For the fracturing facilities, improvements were given on transportation performance and installation workability of the preliminary observation device, by utilizing the experience obtained in the previous fiscal year. A composite (divided into two units) centrifugal multi-stage pumping device was developed so that a water injection test can be performed in a wide capacity range according to the intended wells, where nearly satisfying performance was derived. For the fracturing technology, in order for even small test pieces to be capable of evaluating fracture tenacity accurately with consideration on nonlinear behavior of rocks, elasto-plastic fracture tenacity tests were carried out with AE measurement being performed simultaneously.

    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.

    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)

    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.

    Windmills are one of the oldest prime movers and have been used for more than 700 years in Europe. The transition from low speed windmills for grain grinding and water pumping to high speed wind turbines for electric power generation had occurred at the end of 19{sup th} century. This paper, at first, reviews the windmill technologies and the researchers before 20th century. Then describes the back ground of how the wind power generator has existed and how the four pioneers developed their wind power generator. The historical developments of windmills to wind turbines in this century are studied focusing mainly on Danish activities. Then, the effort of the development of large wind turbine such as Smith-Putnum's first MW machine in U.S.A. and other mammoth machine concept are introduced. The new concept machines such as Savonius and Darrieus wind turbines in 1920s to 1930s are also explained. Finally, the novel technologies of wind turbine covering larger machines, variable speed generators, special wing sections for wind turbines, theoretical analysis method of wind turbine performance, offshore wind turbines, and wind turbine control technologies are stated.

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

    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).

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

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

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

    The survey/research project is implemented for establishing environment-compatible energy systems in urban areas by constructing wide-area heat supply networks to exchange energy among cities. This project studies, taking Kanagawa Pref. as the model area, distributions of unutilized energy sources, and possibilities of their utilization for heat supply. There are large quantities of unutilized energy, including waste heat from power plants, general works and cleaning works, and low-temperature waste heat from, e.g., sewage and pumping systems. The district air conditioning promotion areas are selected from those consuming large quantities of heat energy in the prefecture, and their characteristics are grasped. The effects of the networks on total energy consumption of the entire prefecture are estimated for the cases of introducing the district air conditioning systems or wide-area heat supply networks in these selected areas. Introduction of optimum advanced heat utilization systems in stereotyped areas is also considered, in order to predict the effects of introduction of wide-area heat supply networks. (NEDO)

    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.

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

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

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

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

    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)

    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.

    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.

In the effort to improve cell efficiency, experiments were conducted for enhancing bottom a-SiGe cell efficiency for the embodiment of an enhanced-efficiency multi-junction cell, for improving crystallinity in microcrystalline silicon through the application of VHF (very high frequency) plasma CVD (chemical vapor deposition), for texturizing metal electrodes on a film substrate, and so forth. In the effort to increase the film fabrication rate, a VHF plasma CVD device was used for studying the effect of the discharge frequency on film deposition and quality, Vpp between the electrodes, and so forth. Studies about the high-throughput production technology centered on the film substrate solar cell process technology and the designing of an optimum geometrical pattern for SCAF (series-connection through apertures formed on film) cells. Production cost was estimated for the SCAF structure film substrate solar cell manufacturing process, and a production cost of 147.1 yen/W (in case of 100 MW/year production) was obtained as achievable under the currently available conditions.

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

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

    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 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.

    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.

    Regulations, conventions and agreements relating to the discharging liquefied carbon dioxide (CO2) into the bathypelagic zone from a cruising ships are investigated. The ocean storage of CO2 is not specifically prohibited by law, but must be regulated on a global scale because such treatment may impact the marine environment. In principle, treatment with impact on the nature is prohibited. Laws of environmental conservation are completed in European, Asian, and Pacific countries, which join international conventions and committees with high interests. It is suggested that the engineering technique of the storage should be improved to observe regulations and that an impact assessment for the ocean storage should be carefully conducted in full understanding of the basic premise of the regulatory systems or organizations. Furthermore, it is significant to study on the possible effect of the ocean storage of CO2 on global warming and life-cycle assessment inventory analysis, namely the balance of the energy budget between the separation and the ocean storage of CO2. 23 refs., 7 figs., 6 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.

    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.

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

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

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

    Networking is being executed with an objective of exchanging information on global environment technologies at an international level. In order to further promote the information exchange, and to make web sites user-friendly, fiscal 1998 has performed structuring a thesis renewal system. As a result of structuring the thesis renewal system, researchers can use the system as using a word processor by inputting data from a terminal in their laboratories. The data can also be made into a data base nearly semi-automatically. In addition to reducing time loss, delay and input errors because of re-entry, the researchers can make the data into a database on nearly a real time basis, and can provide their own theses to any part of the world through Internet. With regard to retaining Internet security, the security software having been introduced last year was renewed. In addition, detailed status such as daily access has become possible of identification as a result of introducing the net intellect. (NEDO)

    The R and D were carried out on a system by which the long life of coolant of machine tools can be achieved and a system to process waste efficiently, economically and with less environmental loads, and the FY 2000 results were summed up. In the R and D of a system to prevent degradation of low energy coolant, measurement was made of effects of the degradation prevention system at a laboratory level, and it was found out that propagation of bacteria causing the degradation can be prevented with pH kept high. Further, it was admitted that the alkali effect on metal formability was not very much. As to the coolant processing, in the present situation, most of the coolant is taken back by industrial waste processing dealers. So, the development of the low energy waste liquid processing system is earnestly desired. In the R and D of the low energy waste liquid processing system, test on characteristics evaluation was conducted about each method of systems. Subjects to be improved/solved were extracted such as the point that volatile organic matters are included in condensed water after evaporation of waste liquid and there seems to be a possibility of needing the secondary processing.

    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)

    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.

    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.

    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.

    While a cement manufacturing process generally performs sintering by using a rotary kiln, a development work has been carried out as a subsidy operation of the Agency of Natural Resources and Energy on a cement sintering technology using a fluidized bed consisted of two furnaces: a jet flow bed granulating furnace and a fluidized bed sintering furnace. This paper reports the results of tests and researches performed during fiscal 1995. A plant with a scale of 20 ton-a-day production started in 1993 after having gone through bench scale tests. The year 1995 conducted by August its performance evaluation, review of the operation method and the safety criteria, and generalization of the tests. A multi-stage cyclone system has been employed in the preheating equipment for cement material powder. A number of improvements have been realized in the aspects of construction and operation, such as stabilization of dust collecting efficiency by employing a high-efficiency type cyclone, and operation with reduced pressure variation. Based on these results, a construction had been progressed in parallel on a new plant upscaled to 200 ton-a-day production. The new plant was completed in December, 1995. 9 figs., 8 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. Fiscal 1995 has conducted investigations on coal gasification technologies, air separation technologies, and gas refining technologies as the important element technologies, and a trial design on integrated coal gasification fuel cell (IGFC) systems. This paper reports from among the above items the result of the trial design on an IGFC system using molten carbonate fuel cells. The paper describes system comparison on paths of produced gases and anode waste gas, comparison on refining processes using a wet system and a dry system, and parameter studies on oxygen concentration in gasifying agents. It was made clear that the suitable furnace is an oxygen blown coal gasification furnace, and the power generation efficiency at the system terminal can be higher than 53%. 11 figs., 6 tabs.

    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.

    Coal ash tends to become containing more unburned carbon and porous substances depending on conditions of combustion, whose adverse effects to products due to water adsorbability, absorbability and color tones create obstacles in its utilization. Therefore, research and development works have been progressed on wet type carbon removing technology which is characterized in that coal is pulverized to preferable degrees and subjected to flotation. This paper reports the results obtained during fiscal 1995. The results may be summarized as follows: as a result of the comparison test on a column flotation machine and an FW type flotation machine of machine stirring type, the former machine showed better flotation efficiency; several methods were investigated on crushing as a treatment prior to flotation, whereas a mixer with greater circumferential speed and a homo mixer showed the highest efficiency; strength of the impact to the flotation efficiency was found to decrease in the order of pulp concentration > pretreatment time > collector addition ratio; and as a result of the evaluation on refined ash as a cement admixture and carbons as fuel, possibilities were found in them for practical application. 16 figs., 2 tabs.

    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.

    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)

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

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

    This report introduces the practical examples of the present system of execution manegement. Necessary functions and basic problems are described as well as the possibility of utilizing hydraulic/pneumatic pressure for the automation or the robotization which are the future technical problems. Application examples are also shown on the execution management system by means of an accelometer which was developed by the authors. This area is not long after the start of study. Essential points of the execution management of the batter piles are that the front tips of the piles are confirmed to be securely penetrated to the specified depth in the specific support layer giving the required supporting strength at the same time. For this purpose, what are required are to accurately measure the penetration displacement of the piles and assess the maximum penetration and final penetration and the amount of the rebound. Then the support strength should be checked from the dynamic support force. For this, it is required to develop an execution management system which is simple and adept for the operation at the spot. 9 refs., 12 figs., 5 tabs.

    This paper analyzes how much of the power demand could be reduced in the future by improving efficiencies of electric power utilizing appliances used in the residential and commercial sector. It discusses whether the reduction would lead to load leveling. Annual load rate in the power demand is continuing to decrease because of power demand increase in the residential and commercial sector, and increase in demand for air conditioning in summer. If a technology to improve electric appliance efficiency is proliferated to its maximum scope, the annual load rate in fiscal 2014 may be improved by 1.1 percent point. Since the improvement allows new power generation facility installation cost to be deferred, the power generation unit cost can be reduced by 0.11 yen per kwh. If a heat storage type air conditioning technology is proliferated to its maximum scope, the annual load rate in fiscal 2014 can be improved by 1.8 percent point, and the power generation cost may also be reduced. If the device efficiency improving technology and the heat storage type air conditioning technology are introduced to their maximum simultaneously, the annual load rate in fiscal 2014 can be improved by 2.5 percent point, and the power generation cost may also be reduced by 0.24 yen per kwh. If a promotion policy is taken on proliferation of a specific device efficiency improving technology having excellent economic performance by providing subsidy, the reduction amount of cumulative power generation expense will be much greater than the required subsidy amount. 10 refs., 9 figs., 22 tabs.

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

    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.

    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)

    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)

    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%.

    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.

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

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

    The project intends to improve on large-area amorphous silicon solar cell performance and to develop high-throughput manufacturing technologies for a reduction in the cost of modules. A film substrate type amorphous solar cell structure of the serial connection type named SCAF (series-connection through apertures formed on film) is contrived.

    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.

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

    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.

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

    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 techniques used for the evaluation were the following six ones: The first one is to plant trees on wastelands located in the tropics and the subtropics and CO{sub 2} is immobilized by grown trees. The second one is to compulsorily blow CO{sub 2} into water to immobilize CO{sub 2} by multiplicated microorganisms such as green algae. The third one is to multipulicate phytoplanktons by spraying deficient trace elements on oceans where trace elements such as Fe are deficient in spite of rich nutritive salts to absorb and immobilize CO{sub 2}in seawater. The fourth one is to multipulicate shellfishes in coastal regions to immobilize CO{sub 2} in seawater as their shells. The fifth one is to multipulicate many coral reefs in tropic or subtropic coastal regions to immobilize CO{sub 2} as calcium carbonate. The sixth one is to multipulicate large size seaseeds such as giant kelps in shallow seawaters to immobilize CO{sub 2} in seawater.

    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.

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)

    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.

    Researches have been conducted on deca-nano quantum integrating transistor substrate technologies, and developments were made on a three-dimensional device simulator which can be used in deca-nano domains, and a circuit simulator to have quantifying function transistors coexist with silicon semiconductor integrated circuits. The researches were intended to develop a simulator capable of analyzing properties of very small silicon and compound semiconductor devices in deca-nano domains. The researches discussed the applicability of conventional simulators, calculated quantum levels in a three-dimensional hetero structure, and resulted in development of an electron wave propagation simulator in optional two-dimensional shapes, a quantum Monte Carlo simulator, and a three-dimensional semiconductor device simulator with quantum correction. On the other hand, in order to estimate characteristics of a hybrid circuit in which single electron transistors coexist with conventional transistors such as CMOS transistors, a single electron hybrid circuit simulator was developed. The development indicated that a CMOS-SET fused memory is promising as a future LSI memory. 22 refs., 116 figs., 3 tabs.

    In relation with several types of standard photovoltaic power generation systems expected to be put to practical use, design parameters are quantified, databases are utilized, and simulation technologies are developed, while collecting data from test facilities constructed to simulate them, for the development of evaluation techniques indispensable for the efficient improvement of photovoltaic power generation systems. In fiscal 1998, data were collected from verification test facilities and residential photovoltaic systems sited across Japan. The collected data were subjected to analysis and simulation, by which correction factors were calculated for smudge, spectral response, incident radiation, and temperature. Furthermore, load matching factors and storage battery contribution rates were calculated by simulation for the stand-alone photovoltaic systems sited in five Japanese cities, each comprising an array, storage battery, charge/discharge controller, DC-DC converter, and a load. Reference is also made to a survey of trends of technology development. (NEDO)

    Research and development has been made on a wooden board manufacturing technology re-utilizing demolished building lumbers and waste plastics with an intention of saving resources and reducing wastes. This paper summarizes the achievements in fiscal 2000. In developing the technology to re-use demolished building lumbers, a method for removing metals attached to demolished building lumbers was established by using a magnetic separator and a metal detector, with which it was verified that iron can be removed nearly 100%. With regard to waste plastics, simultaneous use of specific gravity separation utilizing centrifugal force and electrostatic separation provided a prospect that metals and plastics of high melting points can be removed from mixed resins in waste household electric appliances, and that polypropylene (PP), polystyrene (PS), and ABS can be classified at high accuracy. In manufacturing waste wood and waste plastic boards, pilot plants were built to use the 'melt spray method', 'melt blow method', and 'laminating method' as the means to spray molten resin onto wood raw materials, wherein trials were performed on mixing molten resins with wood flakes, and on board forming.

    Element technology is studied to realize a reflective-type, full-color, and high-resolution liquid crystal display for super-low power consumption data display. As to the functional compound microstructure formation technology, a 4-inch panel was trially fabricated using two-layer guest-host liquid crystal technology to achieve the desired display performance by control of molecular orientation. Further, holographic PDLC elements were favorably test-fabricated. A ferroelectric PZT thin layer was formed by forming layer at low temperature at which a glass substrate can be used. Optical interference/optical dispersion type optical control materials were studied by liquid crystal/polymer composition. Also studied were super-pure/super-reliable liquid crystal compound/liquid crystal composite systems and super-anisotropic liquid crystal compound by modeling ionic impurities and liquid crystal molecular interaction. In relation to the control technology of optical reflection characteristics, effects of liquid crystal molecular structures (derivative effect and copolymer composition) on orientation were elucidated. As to the technology to form multi-dimensional anisotropic structures, efforts were made for the heightening of formation technology of simple RGB (red, green, blue) directional reflection layers using acrylate materials. The paper also outlined the comprehensive survey. (NEDO)

    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)

    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. Efforts are exerted to develop a hydrothermal fluid analyzing technique using a rapid rock dating method and traces of chemical ingredients in hydrothermal minerals. (NEDO)
