    Described herein are the final evaluation results of the basic research and development of the system for exploiting manganese nodules as one of ocean resources. A 9-year project was started in the FY 1981 to establish the techniques to efficiently, economically exploit Mn nodules on a commercial basis, which are occurring on deep sea bottoms (4,000 to 6,000 m deep), in order to stably supply non-ferrous metallic resources, e.g., Ni, Cu, Co and Mn, which are essential for economic activities of Japan. Originally, the UN convention related to ocean laws raised development of unique exploitation techniques as the prerequisite condition for obtaining the right to develop Mn nodules. However, the situations around development of Mn nodules were changed since then, to devalue objects, significance and urgency of this project. The fourth amendment of the basic plans decided to suspend the comprehensive ocean tests in 1996, and to implement only the ocean/land tests in which part of the individual elementary techniques were combined. Therefore, the technological validation of the overall system could not be done sufficiently, and degree of achievement of the project is low, viewed from insufficient prospects of the commercial production. However, this project produced good results in individual elementary techniques, which are of significance for the resources policies. (NEDO)

    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.

    Described herein are the final evaluation results obtained by the 7-year R and D project, beginning in the FY 1976, established by the national project system for developing the techniques for treating urban solid wastes. This project has developed a semi-wet type selective crushing/sorting unit for sorting the wastes, and established the elementary techniques for recycling the wastes into various products, e.g., compost, pulp, combustible gases, aggregates, methane gas, or fuel oil. Two types of total treating systems, in which these elementary techniques are integrated, have been developed; one is to recover materials and the other energy. They can comprehensively, efficiently treat the wastes, adapting themselves to various situations. Pyrolysis which discharges reduced quantities of flue gases is adopted. Waste water is treated, mainly by biological treatment which is supported by the conventional methods, e.g., coagulation and adsorption. The cost estimation results indicate that the total system developed by this project can compare favorably with the conventional incineration system under general conditions, at a capacity of 300 t/d or more, when taking into consideration the secondary effects brought by the recycling/reutilization. This system is commercially feasible, when it meets with local characteristics, e.g., garbage collecting systems, market values of recycled resources, treatment/disposal conditions, and natural and social environments. This project has sufficiently achieved the original objectives. (NEDO)

    The deep-sea manganese nodule mining system in this report collects efficiently and continuously a large quantity of manganese nodules in existence in the 5,000m-deep sea floor. The aim of the project is to develop and build an experimental system for a real mining machine and to perform a comprehensive marine test to find out if such a real machine is technologically and economically feasible. The system under this project is divided into four systems, which are a nodule mining system, nodule lifting system, nodule handling system, and a measurement control system. The nodule mining system travels on the sea bottom efficiently collecting manganese nodules and forwarding them into the nodule lifting system. Only a few systems of this kind have so far been developed, however, and therefore much endeavor needs to be exerted for the development of technologies involved. The nodule lifting system is divided into a pump lift unit, air lift unit, and a nodule lifting pipe. The pump lift unit and air lift unit elevate manganese nodules supplied from the nodule collecting unit to the sea surface. The nodule lifting pipe provides a passage for nodules to run through upward. (NEDO)

    The paper reported on the research, design, and evaluation on a system to recover by sedimentation magnesium from the brine in the salt manufacture by solar evaporation in Mexico, and a system to recover by adsorbent lithium, boron, etc. from the brine of the solar pond salt field in China. In the case of Mexico, an overall recovery system was developed, but in the evaluation of economy of the system, it cannot be said that the system is feasible even if assuming that the required fresh water can be secured. It was found out that the economical efficiency largely depends upon the cost of hydrated lime and the selling price of magnesia clinker. In the case of China, a plant for production of 500 tons/year of lithium carbonate was conceptually designed to evaluate the economical efficiency. As a result, the internal profitability of the plant is not so high, approximately 6%, though continuously profitable during the operation of 15 years. It was indicated that the project was not economically very efficient. 164 figs., 44 tabs.

In relation to polymeric materials, in particular, a new technology is developed that equips, with high reproducibility, polymeric materials with conductivity similar to that of silver or copper; a graphitic material is created for the first time provided with conductivity superior to that of metals; and conducting polymeric materials are equipped with an easy-to-machine feature. A great contribution is accomplished to the production of superconductivity in organic charge-transfer complex crystals and to the elucidation of the conducting mechanism. (NEDO)

    Development was made on a technology to evaluate quality of composite materials. Few data are available for environmental resistance of composite materials, whereas identification of environmental deterioration behavior and establishment of a environmental resistance evaluating technology are a significant issue in utilizing these materials as new materials for space, aeronautics, and marine applications in the future. The present research was taken up with objectives to elucidate deterioration behavior of composite materials exposed to special environment in the atmosphere and space and to establish methods for acceleration tests and environmental performance evaluation by using simulated environments equivalent to the natural environment exposure. The former period (fiscal 1982 through 1984) has investigated environmental conditions in the atmosphere and space, prepared standard test specimens, performed design on environmental devices simulating the environmental elements, as well as tests on deterioration due to environmental elements, and systematized the deterioration characteristics to establish composite test conditions. The latter period (fiscal 1985 through 1988) has developed the composite environment testing device based on the result achieved in the former period, elucidated the deterioration behavior under the composite environmental conditions, and performed evaluation tests on the developed composite materials (FRP).

    For the purpose of contributing to the resource recycling and global environmental preservation, the R and D of metal base scrap regenerative utilization technology were conducted, and the report on the finally obtained results was summed up. As to the technology to remove impurities by the solid phase treatment, the Cu removal rate of more than 96% was made possible by the low temperature fracturing technology, and that of more than 90% by the hue difference discrimination separation system technology. From the results of the FS on the low temperature fracturing technology applied to car scraps, it was found out that the present price condition is not economically efficient in the present price condition, but a possibility of achieving the removal rate of 54% in the initial plan was obtained if applying the hue difference discrimination separation system to the pretreatment. Concerning the Sn removal, the Sn removal rate of more than 70% was obtained by the gaseous phase sulfuration method, and that of more than 50% was obtained in Sn removal/Cu removal/Zn removal by the oxidation reaction method. The targets were achieved. Relating to the treatment of impurities by melting (liquid phase), the Cu removal/Sn removal technology under reduced pressure was effective in vacuum melting furnace of 2-ton scale, but the needs for the development of large capacity plasma torch were recognized in that of 40-ton scale for practical use.

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

    Development of a bituminous coal liquefaction technology (NEDOL method) can be judged appropriate as a national project in the comprehensive view with the 21st century just around the corner. It is a fact that this project has spent the national budget not in a small amount. There is no prospect of the technology to be put into practical use in Japan at the present time. The coal liquefaction technology is a technology required inevitably in the situation where shortage of crude oil supply may endanger the existence of a nation. Therefore, there is sufficient significance in having demonstrated the effectiveness of the NEDOL method which can be applied to a large number of coal types and expected of high liquefaction yield. The contents of the 'technological package' to be prepared are so demanded that its usefulness can be retained until the time of a demonstration plant design and operation will come in the future. It is also desired that the human resources and the testing devices will be kept ensured, and the technologies developed under this project will be maintained and expanded. The present technology has low necessity of immediately putting into practical use in Japan at the present time. However, the technology should be kept available for use at any time, and retained for use in an urgent situation. (NEDO)

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)

    To promote the development of deep-seated geothermal resources in a rationalized way, studies are conducted about deep-seated geothermal resource assessment techniques, development guidelines, and the like. Data were collected at the Sumikawa-Onuma district, Ogiri district, Mori district, Yanaizu-Nishiyama district, and the Onikobe district, and compiled into a database to be open to the public. Studies were made about methods for estimating parameters for deep-seated geothermal reservoirs. The resultant findings indicate that, in the Uenotai and Sumikawa-Onuma districts where geothermal reservoirs are governed mainly by a fracture network, the relaxation method and extrapolation will be effective for deep-seated reservoir temperature estimation, and the ascending current analysis method and extrapolation for permeability estimation. The findings also indicate that the expanse of deep-seated reservoirs will be suitably estimated using a method similar to that applied to shallow-seated reservoirs. In the study of the estimation of the amount of deep-seated geothermal resources, it is concluded that the simplified model A will be effective in dealing with a geothermal district where there is a well-developed fracture network and the simplified model B in dealing with a geothermal district where supply of deep-seated fluid governed by an extensive fault prevails.

In FY 1995, conducted were the field survey, support study in Japan, acceptance of researchers from Kazakhstan, conceptual design of pilot plant, etc. The ore/mineral for Cu is mainly an alteration ore of chalcopyrite. Au and Ag are low grade and unknown, and the main gangue mineral is pyrite. The low grade ore (waste/much) of the Nikolayevska mine has a tendency to leaching at normal temperature, but the ore of mostly chalcopyrite such as tailings from each place has difficulty in leaching. It gets leaching by increasing temperature. The more the temperature rises, the more conspicuous the reaction becomes. Further, chalcopyrite is leached with priority over pyrite. From the result, a technical potentiality was obtained of leaching of low grade chalcopyrite in tailings mostly of pyrite. The existence of Thiobacillus ferrooxidans was confirmed. As to the recovery method for Au and Ag, CIC is studied. The process of waste/much is solvent extraction, electrowinning study and leaching, and that of tailings is bacteria leaching and leaching study. (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)

    It is necessary in the field of post-genoms to know statistical correlation between DNA orientation information and clinical data, which helped growth of DNA probe arrays (DNA chips). However, it is difficult in patent point of view to develop chips in Japan. On the other hand, a movement has begun to use beads fixed with DNA probes in place of DNA chips demarcated on the surface of solids. This is a method to investigate hybridized DNA by means of fluorescent detection, in which each bead retaining the DNA probes is colored to make identification of the retained probes possible, and hybridizing reaction is performed in aqueous solution. Hitachi has developed a DNA measuring technology using bead arrays. The bead array has probe fixing beads of about 100 {mu} m laid sequentially inside a capillary, wherein the array can be used to inspect a large number of genes. Thus, this method can be a DNA measuring technology which is inexpensive, and high in reproducibility. These features lead to a belief that the technology is suitable for gene inspection devices used in the process of medicine development and at the clinical sites. (NEDO)

    As for the collection of sensible heat, 1/3 of blast-furnace slag is treated to the purpose at the Teesside Technology Centre, Britain, but none is collected in the latter half of tapping in case there is so much slag that cooling cannot be done in time. In the case of a large blast furnace, some measures have to be contrived because molten iron comes out of the furnace intermittently. In Germany, the heat collection rate is as low as 3%, with no effort made at heat collection. In North America, desire to develop such a technology is not strong. A visit was made to the Institute of Ocean Sciences, Canada, in relation to the concept of using steel slag as a eutrophic source for marine photo-plankton. A large-scale long-term test is under way for examining the relationship between global warming and ocean current circulation. There are possibilities that Japan will enter into the project for a joint study, for example, of heavy metal elution from slag though the test fails to name slag as the direct object of study. Not only for Canada but also for any other country who faces the sea, it may be a meaningful national policy to inject some active ingredients into the sea for an increase in living marine resources. Greece is engaged in the ocean dumping of nickel slag on an experimental basis but, in view of the purpose of the experiment, Japan will not be a participant in the project. (NEDO)

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

    This paper reports the achievements in fiscal 1999 on development of gas hydrate resources. As a result of synthesizing gas hydrates in deposit systems, identifying stability zones in compositions, and studying thermal conductivity and dielectric constant of the deposits, the estimation accuracy has been enhanced steadily in estimating hydrate existing areas in actual frost areas. In the collecting technologies, a proposal was presented for a system by which carbon dioxide is introduced into ground beds at the same time as recovering gases, and gas hydrates are displaced with carbon dioxide hydrates. The displacement phenomenon was verified experimentally by controlling temperatures and pressures. Even below the freezing point, the production rate of the carbon dioxide hydrates is fast if it is above minus 4 degrees C. Salt diffusion behavior important in control of the production and decomposition, and action mechanisms of production and suppression agents were made clear microscopically. Experimental and theoretical discussions were given on dynamics of the production and decomposition. The cage occupation rate of methane hydrates was quantitatively measured successfully by using the Raman spectroscopy. Hydrates of gas mixture were utilized to have verified the possibility of separating the gas mixture constituents. (NEDO)

    Presently, the aluminum demand in Japan is approximately 3.8 million tons, and the aluminum discharged as scrap reaches approximately 1.7 million tons/year. Out of the discharged scrap, 54% is recovered as the secondary metal, and the rest, 0.77 million tons, is not recovered and dumped for land reclamation. In future, if the present cascade type recycling goes on, it is predicted that a gap between supply and demand of about 0.5 million tons will arise. To cope with this problem, the following are the measures to be taken : 1) development of the technology to promote the use of recycled aluminum metal for automobiles in which a lot of aluminum is most likely to be used because of the increasing fuel consumption, etc. 2) establishment of a recycling system by which the waste sash discharged in quantity from the construction field is again used as sash. From the two points of view, which are needed in the case of using a lot of aluminum for automobiles, the heightening of competitiveness in the aluminum industry and the recycling in which the aluminum expanded materials used for automobiles are efficiently recycled as expanded materials in the recycling economic system, this survey extracted problems and made proposals, overlooking the state of the aluminum use in automobiles, state of the treatment of used cars, state of manufacturing/processing technology of aluminum products.

    The R and D project has been implemented for the bio-recycling technology, in order to produce the extracts and enzymatically hydrolyzed products from unutilized protein-containing resources, e.g., pig skin and fish scale. This paper summarizes the FY 1998 results. This project uses fish scale and pig skin containing collagen protein, and feather meal containing keratin protein, as the major feedstocks. High-molecular-weight collagen is extracted from the pig skin, and applied to production of cosmetics. It is concluded that the extract is safe to the human skin, and can be commercialized as a stock for cosmetics. A low-molecular-weight oligopeptide is produced from fish scale by enzymatic hydrolysis. It is concluded that the oligopeptide can be commercialized as a stock for health foods, because of its anti-radical activity and function of decreasing blood pressure. The R and D efforts are also directed to development of calcium apatite, recovered from the de-ashed liquid, as the Ca source for health foods, and development of peptide, recovered from feather meal by enzymatic hydrolysis, as a stock for foaming agent.

    This report describes effectiveness of a system for measuring the acceleration and force in high accuracy by combining a laser interference meter and a vibration stand. A possibility of pressure sensitive paper to the impact force measurement in the collision examination is also described. The results obtained in FY 1997 are as follows. For the investigation of calibration system of acceleration and force sensor, one-dimensional interferometer system has been developed, which is standardized in ISO5347 accelerometer calibration. Thus, an interference fringe processing software has been made. Moreover, construction of a three-dimensional interferometer system has been started. For the characterization evaluation of pressure sensitive papers, it was succeeded in obtaining an elasticity wave pulse maximum about 1 msec by adopting the flight body made of resin. As a result, evaluation of the force sensor in the frequency area has become possible. To calculate the displacement of a body structural material in the collision experiment, an acceleration sensor has been made for trial purposes. For the international research cooperation, the working plan of a joint research with US Texas Christian University has been concluded. 11 refs., 73 figs., 23 tabs.

    This paper is a survey report for fiscal 1999 related to investigations on evaluation on impact (influential effect) of research and development investments, and on optimal resource distribution. First, a quantification analysis was performed on the impact imposed by the New Sunshine Project having been executed in the past. The analysis used as the base the regressive analysis between the project techno-stock (an index of the project budget amount depleted by a certain obsoletion rate after having been substantiated and aggregated) and the number of theses. In a case where time-series data can be obtained on the quantity of practical application, the regressive analysis was also performed between the number of theses and the quantity of practical application. A large number of projects are stimulating research and development activities of the subject themes of all about Japan. Some are imposing great influential effect on the practical application. In addition, it was found that emphasized and concentrated investment cases in the initial stage of a project have high influential effect. As a budget distribution pattern, the concentrated and emphasized investments in the initial stage of a project are more effective than investing dispersedly over an extended period of time. Suggestions were acquired on the future budget distribution. (NEDO)

    Innovation plays an important role for Japan to flexibly utilize its achievements for the purpose of properly responding to new business environments and to secure competitiveness in the market. Japan lacks experts equipped with knowledge and ability as regards technology development and management which are necessary for the planning and creation of technologies, and is also short of institutes for raising experts. In America, technology management won an important position in the 1980s in the effort at industrial renovation, and the industry, government, and academia in a body endeavored to elevate the level steadily, continuously, and deliberately, to eventually provide a source of great propulsion and international competitiveness toward today's economic success. Investigations were conducted, and a proposition is made for the establishment of an international technology management research center. Such a center will study technology management and innovation through international exchange based mainly on the industrial circle and through the organic coordination of the industry, government, and academia for widely observing changes in international society for economic frontier cultivation. A practical training and intelligent network will be organized on the global scale, which will serve as an information transmitter. A skeleton of the plan is shown. (NEDO)

    Living standards improving in developing countries especially in China are the most influential factor to determine the demand for Cu. Consumption of Ni will depend on the trends of advanced technologies such as Ni-hydrogen battery, fuel cell, shape memory alloy, hydrogen absorbing alloy, in addition to increase in global population and developing countries' living standards improvement. Co is far more dependent on advanced technologies than Ni is. On the land, Ni ore is increasingly lower in quality and Co is being retrieved from by-products of Cu production, both meeting the problem of unstable supply. Consideration is made to apply new extraction methods to Cu production; there are some potential resources for Fe and Mn. The Mn nodule exists in great quantities and is a attractive source of supply, but a long time will be required before it is exploited. It is necessary to speed up the study to exploit the Mn nodule, but first of all the problem of its competition with land resources in terms of cost has to be solved. It needs to be found out at what stage of production the Mn nodule is competitive with land products. In any case, Japan should undertake the efforts of marine resources exploitation leading other countries of the world. (NEDO)

    Though being one of the most impoverished countries with a per capita national income of 225 dollars (1989) because of instability in its political situation, Myanmar is blessed with abundant underground resources. This paper describes the current status of their production and development. Oil fields located in the central sedimentary basin produces 58 million barrels of crude oil and 35 billion 650 million ft[sup 3] of natural gas, but the production is a little insufficient to meet the national demand. Petroleum production is carried out by the operating organizations and departments under the control of the Ministry of Energy. The production has been decreasing since the peak in 1984 because of aged facilities. The government is exerting efforts on production increase and developments leveraged by foreign capital investments. Coal is produced annually at 40,000 tons in the north-west area, all consumed domestically. Such natural resources as copper, zinc, lead, gold, and precious stones are produced by the operating organizations under the control of the Ministry of Mining. Although the country is blessed with an extremely great variety of underground resources, its actual situation in the national economy expects strongly cooperations from other countries including Japan. 6 refs., 2 figs., 1 tab.

    Molybdenum is produced mainly from molybdenite, and the majority of this ore is exploited from the porphyry deposit. The reserve is estimated at 5.5-million ton. A total of 118-thousand ton was produced across the world in 1995, in the U.S., China, Chile, and Canada, the countries named in the order of quantities they exploited. Molybdenite is first refined by flotation for the production of a sulphide. It is subjected to oxidizing roasting for conversion into crude molybdenum trioxide, which is next subjected to extraction in warmed-up aqueous ammonia and then to evaporation for the crystallization of ammonium paramolybdate. The crystals are baked for conversion into molybdenum trioxide of the ordinary purity, to be further processed into ferromolybdenum, molybdenum compounds, molybdenum powder, etc. In view of the magnitude of demand, the metal is used mostly for the manufacture of special steels and special alloys. The demand for this metal, though small in size, involves important articles, such as line materials for semiconductors in the power industry, catalysts in the chemical industry, and lubricants. Japan`s stockpile includes molybdenum, but the U.S. has been stockpiling none since 1977. 9 refs., 4 figs., 1 tab.

    The purpose of this verification survey is to verify the effectiveness of a system using capacitor for power load leveling and output leveling in the photovoltaic power generation. For the former, the charge is conducted in the nighttime, and the discharge in load peak time in the daytime. The capacity required is small for the output, and therefore, there is a viability of capacitor. For the latter, abrupt output variations by solar cells are leveled by storage device using capacitor. Since the output variation generated in a short time by solar cells requires responsibility and life in case of abrupt charge/discharge, it is suitable to use capacitor. The demonstration use capacitor is an organic stacking type for the former, and an organic jelly-role type for the latter. As a result of the demonstration, for the former, a power storage system which has 32-module series/parallel connection bank switch type + 2-way ac/dc exchanger was made and operated for verification. The overall efficiency of 85% was obtained. For the latter, a system which has 2,400F x 70 series bank, 6,000F x 70 series bank x 3 parallel bank and 3kW solar cells was operated for verification. Much effect of output leveling was confirmed. (NEDO)

    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.

    Coal seam gas is also called coal bed methane gas, indicating the gas existing in coal beds. The gas is distinguished from the oil field based gas, and also called non-conventional type gas. Its confirmed reserve is estimated to be 24 trillion m {sup 3}, with the trend of its development seen worldwide as utilization of unused resource. For the necessity of cultivating relevant technologies in Japan, this paper considers processes of production, movement, stockpiling, and accumulation of the gas. Its productibility is controlled by thickness of a coal bed, degree of coalification, gas content, permeability, groundwater flow, and deposition structure. Gas generation potential is evaluated by existing conditions of coal and degree of coalification, and methane production by biological origin and thermal origin. Economically viable methane gas is mainly of the latter origin. Evaluating gas reserve potential requires identification of the whole mechanism of adsorption, accumulation and movement of methane gas. The gas is expected of effect on environmental aspects in addition to availability as utilization of unused energy. 5 figs.

    In a report on a 'survey for coal transportation system optimization in southern Sumatra' which is to contribute to the improvement of coal exploitation efficiency in the Musi river area in southern Sumatra, the coal transportation system from the coal mine to the harbor is reviewed, scenarios on funding and cost effectiveness and environmental impact are comprehensively examined, and suggestions are submitted for higher efficiency and cost effectiveness. In a report on a 'current utilization status and effectiveness of a non-destructive electromagnetic vibrator shock source,' an electromagnetic vibrator shock source out of several new coal exploration technologies which are combinations of test boring and seismic prospecting is taken up, and is compared, in terms of technical feature and cost effectiveness, with the seismic reflection survey technique that uses an explosive shock source, and then a conclusion is reported that an electromagnetic vibration shock source method is superior. Using the new electromagnetic method, a seismic wave frequency is so chosen as to be suitable for a given depth. Since it is non-destructive and emits less noise, it is expected that it will serve in various fields other than coal mining. (NEDO)

    In a servo PD (positive displacement) flowmeter for oil, a differential pressure transmitter detects difference in pressure between the PD flowmeter input and output ports and a rotor is driven by a servo motor so that the pressure difference between before and after the PD flowmeter rotor will be zero. The design enables high-accuracy measurement across a wide range of flow rates and is not easily affected by the surrounding physical conditions such as viscosity and density. For the development of such a flowmeter, it is necessary to develop a rotor that rotates smoothly free of locking in a steady and uniform flow, to build a visualized model that enables the analysis of flow inside the flowmeter which in turn will enable the determination of optimum differential pressure detecting ports, and to connect a newly developed servo mechanism to the thus determined ports. As the result of the research, a servo PD flowmeter is developed, which is a 50mm diameter prototype employing the Invoflex tooth form which is the waveform for a rotor suitable for a high performance flowmeter. Placed in a generally used oil flow calibration liquid, which is gasoline, kerosene, or the like, it covers a flow rate range of 1:10 and reads with an accuracy of {+-}0.1%. It remains stable in performance and suffers but a little change with the passage of time. (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.

    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.

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.

    1997-03-01

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

  17. Paradigm for new scientific technology; Shinkagaku gijutsu paradigm

    Shindo, Y [National Chemical Lab. for Industry, Tokyo (Japan)

    1995-01-05

    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.

    1996-11-01

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

  19. Evaluation technology of clothing comfortableness; Ifuku tekigosei hyoka gijutsu

    Niwaya, H.

    1999-10-26

    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)

    1980-09-01

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

    1996-08-01

    Effectiveness of livestock industry wastes and vegetable protein added to fish meal in fish farming is tested by feeding the Japanese flounder. In the experiment, a part or the whole of the fish meal protein is replaced by the meat meal (MM), meat and bone meal (MBM), corngluten meal (CGM), or dried silkworm pupa meal (SPM), and fries of the Japanese flounder are fed on the new diets for eight weeks. On a diet containing 60% or less of MM, no change is detected in the fish in terms of increase in weight, protein efficiency ratio, and blood components, indicating that 60% at the highest of fish meal may be replaced by MM. In the case of MBM, it can occupy approximately 20%. As for CGM, the proper substitution rate is approximately 40%. Essential amino acids that the new diets may lack are added for an approximately 10% improvement on the result. The SPM substitution works up to 40%, when, however, the blood components are degraded. The proper substitution rate is therefore placed at approximately 20%. 38 refs., 2 figs., 17 tabs.

    This paper explains the development of marine resources utilization system for energy conservation. The conceptual system is designed to take a large amount of deep sea water of 100 thousand to 1 million tons a day, to utilize it from the viewpoint of energy conservation using its coldness and purity characteristics, to then discharge it to the area of the sea in minimizing the environmental effect as well as obtaining effect such as absorption of carbon dioxide gas through cultivation of phyto-plankton. In pump-up technology, a piping system attaching on sea bed or floating with one or multiple constraints is applicable at present to all sites of geographical and oceanographic conditions. In utilization technology, use of deep-sea water as cooling water at a steam power plant, for example, improves generation efficiency by one point or more. In discharge and environment-related technologies, the research revealed that the deep-sea water from 300 m below releases carbon dioxide gas at surface, while photosynthesis can absorb the gas in the process of using nutrition contained in the deep-sea water; therefore, comprehensive examination is necessary taking energy utilization effect into account. Candidate sites were selected in areas of 200 m depth and within 5 km off-shore, with the optimum system examined at each site. (NEDO)

    This paper reports the survey on hot water in the geothermal development promotion survey in fiscal 1999 in the Tsujinodake area. The hot water pumped up at the N11-TD-2 well is considered to have been originated from sea water mixed with the same amount of meteoric water including waters from Ikeda Lake and Unagi Pond, and been heated mainly by heat conduction. The hot water temperature near the well is 120 to 130 degrees C, but the upper stream of hot water flow is estimated to be 160 to 230 degrees C. The test samples collected and analyzed are those pumped up from depths greater than 1,500 m, having the same origin as the high temperature hot water of higher than 200 degrees C flowing sideways at the relatively shallow portions (depths of 400 to 800 m). The hot water is estimated to be rising from deep portions of mainly the north-east shore of Unagi Pond in which exhalation bands are located, and its temperature is considered to be 260 to 270 degrees C at deep sections. The high temperature geothermal reservoir spreading in relatively shallow sections of the N11-TD-2 well mainly around the vicinity of the north-east shore of Unagi Pond has a high possibility of being continued even to the vicinity of the west Ibusuki area in the north-east direction. However, the spread of the geothermal reservoir with high temperatures (200 degrees C or higher) is considered not too large in the direction of the Matsugakubo in the north-west and the Narikawa area direction in the south-east.

    Research and development has been made on a cover soil replacement process utilizing waste papers for final disposal facility and a soil flow-out prevention process. This paper summarizes the achievements in fiscal 2000. In evaluating waste paper fibers and waste paper binder films, the safety level was assumed sufficiently high if the fibers are used for the cover soil replacement process for final disposal facility. However, films may have a possibility of destruction if force is applied by such as heavy machines running on the films, hence it must be avoided. According to the on-site scattering test using unattended mixed slurry spraying machine capable of being remotely controlled, the coverage was found good, and scattering of incineration residues can be prevented completely. With regard to monitoring of hydrogen sulfide gas, a system having a hydrogen sulfide sensor and GPS mounted on a slurry spraying machine capable of remote control operation was completed, and its usefulness was verified. By using a wastes disposal facility simulating device, investigations were performed on effects on seepage water and wastes when the cover soil replacing material utilizing waste papers is used, and on changes in the properties of the cover soil replacing material.

    This paper explains the 1988 results of the specialized study in the R and D of the observation system for probing resources. In the interface with the satellite body, the result of the 1986 basic design was reexamined, elucidating the interface conditions, while the telemetry command items were also rechecked, clarifying the restrictions of the operation. In addition, the combination tests of mission equipment were all put together. Reexamined also were the interface specifications of optical sensors. Concerning the interface between the satellite body and the mission transmitter, examination was made on the detailed design level. In the operation mission analysis, algorithm for acquiring mission equipment data was reviewed, as were the operation analysis program and the data acquiring simulation. With a case examined in which an optical sensor satellite image was used for probing oil, the conclusion was obtained that the present design specifications were sufficient. In the experiment of the on-aircraft multi-channel image sensor, the subject sensor was found much higher than before in the performance for identifying rocks/minerals and was expected to be useful for resource probes. Image analysis of the test site was also performed. (NEDO)

    The research aims to construct a recyclable resources distribution network in coordination with other Japan Sea countries so as to establish measures for the effective utilization of resources originating in Japan. The research covers the needs in China and in Russia's Far East provinces for used electrical home appliances and the supply capability of Japan's four prefectures on Japan Sea including Akita Prefecture. Demand in the countries on the other side of the sea for three major categories of electrical home appliances (color television sets, washing machines, and refrigerators) for 2010 and 2025 is predicted. Part of the predicted demand is specified to be for used items, and a scenario is built based on the reuse substitution rate. On the other hand, in view of the life time of such commodities and the rate of reusables in the amount of waste generated, a conclusion is reached that probabilities are that all such appliances from the four Japanese prefectures will be put to reuse. When the reuse rate is estimated at 10% for goods under the three major categories from the four prefectures, approximately 20,000 articles out of each of the three categories will be put to reuse, and this will lead to a reduction of CO2 emissions of 7700 tons a year.

All structure/sequence known proteins from all public databases were hierarchically classified systematically and according to similarities among sequences. Individual proteins in each classified group were added with explanatory notes of structure and physiological function. The mutually related information in metabolic system/signal transfer system was also included. The state of each residue position was classified into three states in terms of the solvent accessibility and three states in terms of the secondary structure. Parameter sets of occurrence frequency for each state of 20 kinds of amino acid were made. By these, it can be evaluated how much the arbitrary amino acid sequence is suitable for each structure in database. The data on the structure of low molecular-weight compounds are also incorporated so that the search for the related biomolecular system information becomes possible. The metabolic system/signal transfer system information was made database, the link was formed between each protein and each low molecular-weight compound, and the information on biomolecular networks was made searchable.

    The paper grasps the present situation of economy and industry in Kazakhstan and studies a policy for developing the industrial machine manufacturing industry of the country. Since the independence in 1992, the country is now at the great turning point in politics, economy, society and industry. The country is forced to convert from the industrial structure of one local area where much of its own discretion had not been given under the economy system of power centralization to the industrial structure which meets the international economic market system as an independent country. Making good use of agricultural and industrial property in the former U.S.S.R., the country needs to export energy resource like oil, natural gas and coal, and abundant ore resource like iron and non-ferrous metal, which were added with values. As the technical base for it, fostering and strengthening of the industrial machine manufacturing industry is important. At present, the situation is that because of the economic sluggishness, the country cannot manufacture domestically even basic mechanical parts and simply-manufactured parts which are required by the domestic energy industry, machine manufacturing industry, and other industries. The technical program to be proposed by Japan is planned to be worked out later based on the basic research made in fiscal 1993. 6 figs., 14 tabs.

    The project aims to develop a biocatalyst-assisted synthesizing method for efficiently manufacturing sugar containing polymers and polylactic acids which generate less environmental impact. The ALP-901 derived from actinomycetes operates best with 5% water content, and remains free of hydrolytic effect even when the rate rises to 20%, and catalyzes transesterification only. The esterification activity of bioprase rose remarkably upon addition of water. A polymer with a molecular weight of scores of thousands was obtained in the polymerization of sugar ester monomers. A sugar undecylenate with a double bond at an end was successfully polymerized. The sugar containing polymer exhibited excellent biodegradability. In a reaction of butanediol and lactide, several types of lactic oligomers different in molecular weight were synthesized. The oligomers were caused to react with divinylcarboxylic acid in the presence of an enzyme, and a polymerizable lactic oligomer was obtained. Furthermore, in a reaction between glucose and lactide, several lactic oligomer derivatives were synthesized, different in molecular weight. In a reaction of the derivatives and divinylcarboxylic acid with an enzyme added thereto, a polymerizable lactic oligomer derivative was obtained, which was brought into polymerization in the presence of a radical polymerization initiator for the production of a high molecular weight gel.

In the survey, the following were carried out: surface survey such as geology/alteration zone/fracture system, high-density gravity exploration, electromagnetic exploration, geochemical fluid survey, core test by drilling three exploration boreholes, temperature log, temperature recovery test, water injection test, short-term jetting test, etc. N12-SZ-1 came across the reservoir associated with the ENE-WSW system fault at a depth of 1,085m. The result of the temperature log and the geochemical temperature indicated that the temperature of the reservoir was between 230 and 240 degrees C. However, the reservoir was regarded as the vapor heating reservoir heated by the high-temperature vapor which is thought to be the shallow ground water separated from the deep reservoir. N12-SZ-2 was a large lost circulation zone at a depth between 1,325 and 1,486m, which indicated that N12-SZ-2 came across the ENE-WSW system Shiro-mizukoshi fault. N12-SZ-3 seems to be the area into which ground water flows. (NEDO)

    In Asian countries, the economic growth rate is extremely higher as compared with the world average, and accordingly a large growth in energy supply/demand and electric power supply/demand is paid attention to. Besides, at users` side, a fear is the worsening of the environmental problem which is brought about by a rapid increase in energy consumption. At suppliers` side, introduction/expansion of a large amount of foreign funds for rapid promotion of power source development become necessary so that supplying facilities catch up with the growth in demand. Moreover, dependence of the supply upon outside the area is becoming higher, and problems in safety guarantee are also becoming prominent. As for energy/power source mix in East Asian countries, the stable supply is basically considered as most important, and economical efficiency is also important including competition conditions among energies and potential raising of investment in supplying facilities. It is no exaggeration to say that the increase in the rate of coal which occupies most of the primary energy supply/power source in East Asian countries depends upon the progress of environmental harmony technology such as clean coal technology. 39 figs., 132 tabs.

    Promotion of development of hydraulic power and others as fossil fuel alternative energy sources is one of the most important measures for solving the global environmental problems. This draft plan proposes, first of all, to conduct surveys on hydraulic power resources on a global scale, to collect the basic data for development of the energy sources. It is estimated that developed hydraulic power resources account for approximately 14% of the total developable resources, the remainder being left untouched. By region, these percentages rise to approximately 55 and 45% in North America and Europe, respectively. These percentages in Asia, Africa, Latin America and FSU are significantly lower, and their undeveloped resources are estimated to total approximately 6 times as large as those already developed worldwide. It is expected that the hydraulic power resources are surveyed on a 10-year plan (1991 to 2000) with a total budget of 30 billion yen, to collect the data and establish the databases in cooperation with international organizations, e.g., UN organizations, regional organizations (e.g., ASEAN organizations) and newly founded organizations.

    The research aims to construct a recyclable resources distribution network in coordination with other Japan Sea countries so as to establish measures for the effective utilization of resources originating in Japan. The research covers the needs in China and in Russia's Far East provinces for used electrical home appliances and the supply capability of Japan's four prefectures on Japan Sea including Akita Prefecture. Demand in the countries on the other side of the sea for three major categories of electrical home appliances (color television sets, washing machines, and refrigerators) for 2010 and 2025 is predicted. Part of the predicted demand is specified to be for used items, and a scenario is built based on the reuse substitution rate. On the other hand, in view of the life time of such commodities and the rate of reusables in the amount of waste generated, a conclusion is reached that probabilities are that all such appliances from the four Japanese prefectures will be put to reuse. When the reuse rate is estimated at 10% for goods under the three major categories from the four prefectures, approximately 20,000 articles out of each of the three categories will be put to reuse, and this will lead to a reduction of CO2 emissions of 7700 tons a year.

    Studies are conducted for the development of now-unused kinds of fossil carbon resources, such as low rank coal and heavy gravity crude oil, into higher-value liquid fuel. In the preliminary treatment process, the fossil carbon resources are dried by use of supercritical carbon dioxide, when it is found that the resources are disintegrated and water is desorbed. In a low rank coal liquefaction process using the NiMo/KB (Kefjen Black) catalyst, more than 60% is converted into oil, which rate is improved by use of the dual-temperature liquefaction process. This catalyst may be recovered by separation utilizing specific gravity difference. As a low temperature gasification catalyst, the alkaline carbonate-carried carbon catalyst is very quick at the initial stage of reaction. The perovskite-carried alkaline carbonate catalyst is high in carbon oxidizing/activating efficiency at low temperatures. The silica film deposited on an alumina-coated support tube is excellent in selectivity and speed as a hydrogen separating film, and a carbonized polyimide film as a carbon dioxide separating film. For the supercritical phase adsorption/separation of chemicals not to be distilled easily, the NaY-type zeolite functions effectively. Pd/ZrO2 serving as a carbon monoxide conversion catalyst enables the recovery of more MeOH when Pd grains are smaller in diameter.

    Conceptual design was made on a database system as part of the comprehensive surveys of nationwide geothermal resources. Underground hot water in depths of several kilometers close to the ground surface is a utilizable geothermal energy. Exploration using the ground surface survey is much less expensive than the test drilling survey, but has greater error in estimation because of being an indirect method. However, integrating data by freely using a number of exploration methods can improve the accuracy of estimation on the whole. In performing the conceptual design of a geothermal resource information system, the functions of this large scale database were used as the framework. Further data collection, distribution and interactive type man-machine communication, modeling, and environment surveillance functions were incorporated. Considerations were also given on further diversified utilization patterns and on support to users in remote areas and end users. What is important in designing the system is that constituting elements of hardware and software should function while being combined organically as one system, rather than the elements work independently. In addition, sufficient expandability and flexibility are indispensable. (NEDO)

    For the purpose of corresponding to changes of the industrial structure and making full use of the control technology, the paper investigated the state of the application. High-grade automation in the manufacturing industry has reached the spread of use at big companies for these 10 years. The hierarchical structure of business/process/DCS has been completed, and the optimal control and the advanced control have been realized. The development and spread to the much wider field is anticipated. The soft structure system is needed for equipment improvement in view of the life cycle of equipment and toward the elimination of bottlenecking. For the design of the control system, commercial tools began to be much used, and it is expected in future to accumulate and recycle the knowledge/knowhow for effective design work. Further, strict simulation models based material balance and heat balance have also been on the rise, and the advance in technology is expected. Because of the total productivity of the production equipment, the control technology is anticipated not only for the pursuit of controllability but for the use as supporting technology in the operation/driving/failure diagnosis for working out, carrying out and evaluating the optimum operation plan. 18 refs., 99 figs., 100 tabs.

    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.

    1998-06-10

    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.

    2000-05-15

    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)

    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.

    Miyamoto, I. [Osaka University, Osaka (Japan)

    1998-11-01

    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.

    1997-03-01

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

    This 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.

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.

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

    1998-09-10

    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.

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.

    1997-04-01

    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.

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

However, it has been difficult to calculate the burning area of propellant grain with precise and speed by geometrical way since most of propellant configuration have been adopted as complicated. In the present study, the simulation system was developed and produced, which was adapted `particle chasing method` to and made ot compute the burning area transition. Moreover, the reliability on computation by the system was check up on. It was found that the discrepancy of calculation between by the geometrical way and by the system was less than 1%. (author)

    1990-04-25

    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.

    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.

    1996-09-01

    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.

    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.

    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.

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

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

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

    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.

    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. 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. The paper also describes studies on fracturing fluids. (NEDO)

    Research and development has been carried out on super metals with an objective to draw out properties possessed by iron and steel materials to their maximum extent and further enhance their recycling performance to make them friendly with global environment. The final goal of this project is to 'establish a technology to create micro tissue steel having crystalline particle diameter of about 1 {mu}mm or less and size having thickness of 1 mm or more by making the steel tissues uniform and multiple in phase'. The studies in the current fiscal year were moved forward mainly on obtaining ultra fine crystalline particles of 1 {mu}mm or less, identifying the ideal large distortion processing conditions, and structuring the guidance principles for ultra-fine micronization of the crystalline particles by using large distortion processing. Discussions were also launched on further micronization of crystalline particles by optimizing chemical composition and on expansion of the process windows assuming practical application thereof in industrial scale. Furthermore, material property evaluation was also begun on ultra-fine crystalline particle materials of smaller than 1{mu}mm. As the mesoscopic structure analyzing technology for the ultra-fine crystalline particle materials, an in-lens resolution SEM was introduced, and the basic method was established. (NEDO)

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

    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. The oxidation + coagulating sedimentation method, the autolysis + oxidation coagulation method, and the evaporation method are effected, though the examples of their implementation are small in number. 15 tabs.

    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 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 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.

    Magnesium semi-solid injection molding is safety and clean process. We have investigated influence of molding conditions on mechanical properties and dimension accuracy of products by semi-solid injection molding. As a result it was proved that the accuracy of products by this process is superior to die casting. This advantage as well as better mechanical properties can be utilized for net shape molding of some automobile parts. 4 refs., 8 figs., 3 tabs.

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

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

    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)

    Research and development was conducted for reliable CdTe solar cell modules, large in area and high in efficiency. In the study of large-area CdS thin film fabrication, a conversion efficiency of 12.5-14.2% was achieved in a cell in a large-area substrate using a mist method-aided process of continuous CdS film fabrication. In the study of large-area CdTe thin film fabrication, the optimization was studied of the base-forming CdS film fabrication conditions and of the CdTe film fabrication conditions in a method using a CdTe powder processed by dry kneading, and a conversion efficiency peak was found to exist when the CdS film thickness was in the range of 700-900 angstrom. In the fabrication of large-area submodules, a large-area substrate was taken up, and TCO (transparent conducting oxide) film was fabricated by the mist method, CdTe film by the normal pressure CSS method, electrodes by the screen printing method, and CdTe film patterns by the blast method. As the result, a conversion efficiency of 11.0% was achieved.

    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.

    An investigative study was conducted on phytoremediation with the purpose of correcting soil contamination caused by heavy metals and the like. In Japan, in connection with the cadmium pollution along the Jintsugawa River region in Toyama Prefecture, a growth of botanical colony such as Athyrium ykoscense was confirmed having a high capacity in absorbing/accumulating heavy metals, with a possibility suggested that they may be utilized for phytoremediation. In a technological research for restoring the environment sustainingly in a wide area, feasibility has been proven to remove polluting agricultural chemicals in farmlands and toxic substance in old industrial sites by making forest trees like poplars, lawns and herbage function. In a project for the cleanup of oil contaminated soil after Gulf War, a demonstrative test of bioremediation for one hectare was performed and, after 15 month experiment, 80 to 90% of aliphatic compounds and 50 to 60% aromatic compounds were degraded. In EU Framework Program in Europe, phytoremediation projects have been implemented across the member countries. (NEDO)

    1996-06-01

    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.

    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 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)

    Shioji, M. [Kyoto University, Kyoto (Japan)

    1998-09-01

    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.

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.

    Kobayashi, H [National Aerospace Lab., Chofu, Tokyo (Japan)

    1994-03-10

    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.

    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)

    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.

    1996-09-01

    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.

    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)

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.

    1997-09-01

    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)

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.

    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.

    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.

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

In the 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 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. The width of each applicabe area, immibilizingcapability of CO{sub 2} and the executing cost were considered to evaluate respective methods. As a result, the multipulication of marine planktons were thought most promising. 1 fig., 4 tabs.

As to the manifestation control breeding technology, the actual design of the development of manifestation promotion technology by bent DNA, etc. was proceeded with, and at the same time the following were commenced: selection of bent DNA, confirmation of bent characteristics, and work of vector construction using candidate bent DNA. Further, the simple assessment system of manifestation vectors was constructed. In the development of bioreactor system technology, the actual design was started of the two-stage culture continuance system which separated proliferation and enzyme production. 48 refs., 41 figs., 6 tabs.
