In this project, the excess heat phenomenon caused by electrolyzing heavy water using palladium metal, etc. as electrode was captured as `new hydrogen energy.` To make a possibility of being as a future energy source clear, the abnormal heating phenomenon was verified. By elucidating the mechanism, the paper aimed at quantitatively controlling the heat generation. The R and D period was four years from fiscal 1993, and the details of the research are about the excess heat measuring test, material analysis/development tests, test on detection of reaction products, information collection/arrangement, international research cooperation. As a result of the research, a part of the excess heat measurement was surely able to be reproduced. However, when a confirmation experiment on the excess heat was conducted by another more positive method under the same conditions, it was found that the excess heat quantity was not the absolute excess heat quantity exceeding the measuring sensitivity/errors of the system. Supposing the excess heat of 0.1W order is generated in nuclear reaction, any of reaction products should be detected in a considerable quantity. However, no reaction products were not detected. 42 refs., 241 figs., 55 tabs.

An investigation was given on the relationship between methanol adsorbing behavior of reformed coal surface and oxygen containing functional groups in coal. Akabira bituminous coal was air-oxidized or Yallourn brown coal was decarbonated in oil as a reformation treatment. Both of the treated and untreated coals showed an adsorption heat curve of the Langmuir type. The Akabira coal had its oxygen content and the adsorption heat increased as a result of the air oxidizing reformation treatment. The Yallourn coal had its oxygen content and adsorption heat decreased as a result decarbonation reformation treatment. Oxygen containing functional groups act as strong adsorption sites for methanol, and the maximum adsorption amount depends on oxygen content in the coals. Since the coal surface is non-uniform in terms of energy, methanol is adsorbed first into sites with higher molar adsorption heat, and then into lower sites sequentially. Therefore, distribution of the molar adsorption heat can be derived from the relationship between adsorption amount and adsorption heat by changing methanol adsorption amount. The distribution of molar adsorption heat becomes broader when the oxygen content is high, and narrower when low. 2 refs., 2 figs.

The Japanese approach approach to financing LNG project has been what could be called a combined purchase and finance system which has been arranged mainly at the initiative of japan's Sogo Shosh (general trading companies) with the support of japanese governmental financial agencies and a purchase commitment from japanese utilities. In the QATARGAS project, despite it being the first greenfield LNG project in decade since North West Shelf Australia LNG project, financing for the LNG plant phase has been successfully arranged through Japanese financing. The structuring of the financial facilities for the QATARGAS project seems to have lessons for future development of the next generation of greenfield LNG projects. Discharge of the parties' liability, proper sharing of the risk burden and reconfirmation of the spirit of mutual understanding and trust among the parties concerned are key factors for the success of any new LNG project in the future.

Described herein is development of superhigh-function electronic computers.This project was implemented on a 6-year joint project, beginning in FY 1966, by the government, industrial and academic circles, with the objective to develop standard, large-size computers comparable with those of the world's highest functions by the beginning of the 70's. The computers developed by this project met almost all of the specifications of the world's representative, large-size commercial computers, partly surpassing the world's machine. In particular, integration of the virtual memory, buffer memory and multi-processor functions, which were considered to be the central technical features of the computers of the next generation, into one system was a Japan's unique concept, not seen in other countries. The other developments considered to have great ripple effects are seen in LSI's, and techniques for utilizing and mounting them and for improving their reliability. Development of magnetic discs is another notable result for the peripheral devices. Development of the input/output devices was started to correspond to inputting, outputting and reading Chinese characters, which are characteristics of Japan. The software developed has sufficient functions for common use and is considered to be the world's leading, large-size operating system, although evaluation thereof largely awaits the actual specification results.

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)

An evaluation test was conducted on SWD (Seismic While Drilling) method as a part of the investigation of geothermal development and promotion. The test was implemented at the time of drilling of N11-MD-3 well in the northeast base area of Busadake, Hokkaido. The test items were such as verification of direct waves propagating from a bit to the surface, identification of signals passing through a fault zone using direct waves and reflected waves, estimation of distance between a fault and a bent zone, and grasping the direction of signal propagation at the time of inclined drilling. As a result of the experiments and studies, following conclusions were obtained. Reflected waves extracted are not necessarily limited to those from a reflection area from which the shape of a fault can be grasped; unless there is a clear reflection area that can be picked up on the surface near a fault, the application of this method is not effective. In an analysis using direct waves, it was possible to obtain an inclined angle of a fault plane from the estimation of velocity structure, propagation route, and assumption of the shape of the fault plane and, therefore, to grasp the shape of the fault. Obtaining reference data is essential for identifying bit signals. (NEDO)

In order to assure stable supply of oil and natural gas resources, and achieve enhancement in ocean development technologies in general, development has been made on the subsea petroleum production system (SBPPS), which is effective in ocean floor petroleum production from oil fields at great depths (300 m or deeper), and can be applicable to continental shelves and continental slopes around Japan. The SBPPS consists of four sub-systems of shafts, pipelines, manifolds, and riser and oil storage, whose basic development targets were established for the total system. The system was given a conceptual design for the total system, and the above four sub-systems were designed according to the conceptual design. The experimenting devices of each system were fabricated on a trial basis while fundamental studies are being made on component technologies, and experiments were performed to verify basic functions of the sub-systems. Developments were made on such operation technologies as the system operation technology, production control technology, safety control technology, and maintenance and repair technology required to operate the SBPPS. On-shore and general off-shore experiments were carried out to verify the functions of the experimenting devices of each system, the comprehensive functions and the operation technology. Comprehensive evaluation was given on the above achievements from the technical, economic and social viewpoints. (NEDO)

This research and development project is aimed at development of the techniques which allow exploitation of manganese nodules occurring on deep sea bottoms (4,000 to 6,000 m deep) on a commercial scale, in order to secure stable supply of the non-ferrous metallic resource and improve general ocean development techniques. This project, established by the national project system, has been implemented cooperatively by the government, academic and industrial circles since 1981. Described herein are the interim results, summarized in the FY 1985. The targets of the phase for developing the individual techniques were set to develop the exploitation system design procedures, and to advance to the next phase by the end of FY 1985, where the consistent, integrated system is to be constructed and tested. The results obtained so far are satisfactory as a whole, both in the elementary techniques and their consistency. The simulations have been conducted, where various conditions are inputted to estimate the movement and exploitation characteristics of the system as a whole in the comprehensive ocean tests. It has been found that the nodule-collecting machine shows nonlinear tracking characteristics (i.e., movement different from that of the exploitation ship), and unsteady movements (i.e., repeated movements of rapid starting and stopping).

The research and development were reported on new refrigerants for compression type heat pumps. From 64 kinds of newly composed ether, CF3CF2OCH3 was developed as candidate compound substituting for CFC-11, and CF3CF2CF2OCH3 and (CF3)2CFOCH3 as those substituting for CFC-11. However, COP of the refrigeration has not been optimized. Global warming potentials were obtained by high-accuracy estimate guidelines. The new refrigerants have no chlorine and therefore no effects on the ozonosphere. Global warming effects also satisfied the present allowable values. There was no problem on human body toxicity in the short-term experiment. Costs of commercially production of the candidate compounds were trially calculated from reaction paths and chemical constitution formulae. Assuming that the raw materials are circulating on the market, plant/equipment investment, production volume, and production cost became 5 billion yen, 1000 tons/year, and 3500-6500 yen/kg in 3 persons/shift and 4 shifts, respectively. This is close to the allowable level which is ten times the CFC-12 price, 5000 yen/KG. The new refrigerants are expected to be fully commercialized in consideration of progress of the composition method and improvement of physical properties in the future. 115 refs., 37 figs., 102 tabs.

The paper reported the R and D of the membrane separation process introduction technology during a period of 1994 through 1998. The membrane separation technology is not associated with the phase change which requires large energy and expected to be an energy saving process. For the production of membranes required of high functions, the vapor deposition polymerization method was considered, and high order structure control of the membrane, control of adhesion and attachment, and control of orientation, and development of the high polymerization technology were required. For the high grade control of vapor polymerization, the substrate surface structure/quality were important. The molecular level analysis of the vapor deposition surface was also needed. Therefore, the paper took notice of STM (scanning tunneling microscopy), AFM (atomic force microscopy) and HREELS (high resolution electron energy loss spectroscopy) as surface atomic/molecular configuration analysis technology, and designed/fabricated and studied the high resolving power and high sensitivity analysis equipment using the analysis equipment which combined HREELS and STM and the analysis equipment using SFG (sum frequency generation) which can detect signals in the low frequency region. Making full use of the highest technology, technology was able to be developed for substrate surface analysis and surface reaction analysis technologies which become the basis of the high performance separation membrane fabrication technology by the vapor deposition polymerization method indispensable for introduction of the membrane separation process. The technology can be the base applicable to a lot of fields where surfaces and interfaces are concerned

A comprehensive evaluation is made upon completion of the automatic sewing system research and development project. The project aims to achieve a 50% increase in productivity through effective use of a multiple-product/small-amount production scheme in small and medium sewing industries. The intelligent cloth inspecting machine (prior to sewing) in a laser-aided cutting system is as competent as the currently used sewing mill inspection system, and the resultant data are effectively utilized in the cutting process. As for the cutter, it is demonstrated that it is more than two times higher in cutting speed than a currently used laser cutting system; that it is sufficiently accurate in avoiding parts with flaws and in pattern matching; and that it is reliable in complying with process information provided. As for the flexible sewing system, it is acknowledged that it correctly recognizes information attached to cut parts and that it joins them with flexibility in response to changes in the material, pattern, or size. As for the high-technology assembling system, satisfaction is found in its automated 3-dimensional sewing of parts received from the previous stage and in its flow of production. As for the 3-dimensional flexible press, the quality after finish is found satisfying. The said systems are integratedly operated, and it is found that the goal of the research and development has been achieved. (NEDO)

Since an phenomenon was found out that NOx emission, which was thought to be increased, will be decreased by burning the high temperature preheated air jetting it at high speed (high temperature air combustion) in industrial furnace, there appeared a possibility of technical breakthrough for achieving the heightening of energy utilization efficiency and NOx reduction by exhaust heat recovery at the same time. This project aims at conducting full-scale experiments based on the basement technology including the theoretical elucidation of the combustion mechanism and high temperature air combustion by using various experimental facilities. Further, making full use of the most up-to-date analysis methods and constructing general-purpose database, the development is also aimed at of high performance industrial furnaces such as various heating furnace, heat treat furnace and melting furnace, with the assumption of prompt commercialization of the results of the development. As a result, targets were achieved such as energy saving of 30% or more, downsizing of 20% and a remarkable NOx reduction. Core technologies of this project are in-system limit heat recovery technology, high temperature air combustion technology, temperature field control technology (furnace temperature leveling technology) and high exergy heat transfer technology (furnace temperature heightening technology).

Wide-band POF covering Gbps as a Japan-made R and D fruit will be commercialized in the near future. It is very important to make an international standard specification for the transmission by the aid of the wide-band POF, which would be basically the standard for the future home networks. The efforts in this year were directed to finding the optimum parameters for widening the band, for which the necessary characteristics related to, e.g., transmission band and bending loss were measured and evaluated, and the specifications covering a certain range were established. The wide POF system is considered to provide the first chance of the optical transmission systems going into homes on a large scale, and the service conditions and regulations for use in homes have been comprehensively studied. These efforts have begun with collection of the measured data in consideration of operating optical elements represented by LD's, their peripheral circuits and the transmitter/receiver assemblies in which they are mounted at S400 or more. Each of the light emitting and receiving sections, including their peripheral circuits, were measured and evaluated, where they were mainly operated at a short wavelength of 650 nm, which is the same as that for the DVD.

Research, development, and evaluation were made on seawater purification for the purpose of supplying inexpensive city water stably in the future. In the research of the high flow rate long-tube type multi-stage flash process, basic characteristics were identified by studying fluidity, heat transfer, deaeration, and decarburization by using a test plant with a capacity of 3,000 m{sup 3}/d. A number of findings were derived in carrying out demonstration studies by using a test module with a capacity of 100,000 m{sup 3}/d. Research on heat transfer pipe materials covered a wide area including copper alloys, titanium and aluminum alloys, and ferrous materials, where a prospect was obtained on materials which may be practically usable in the future as transfer pipes in large seawater purifying equipment. Research on a concrete evaporator body proved that it is more economical than steel evaporators, and has sufficient corrosion resistance even against high-temperature brine. Other activities included researches on effects of contaminated seawater, brine diffusion, byproduct utilization, and total systems. Social and economic evaluations were also performed. (NEDO)

The fiscal 1998-2000 results of efforts to develop cluster diamond (CD)-diffused solid lubricant composite materials expected to exhibit excellent lubrication are stated. Since friction greatly affects machine life and energy efficiency, friction reduction is an important task. Very hard and microscopic CD was utilized for the achievement of a friction coefficient of 0.08. A manufacturing technology for molds 10nm or smaller was developed, which enabled the development of a gear not larger than 8mm. The success will enable the operation of micromachines in the absence of lubrication which is impossible at present. A CD-aided functional layer creation technology was also developed. It is expected that the development and practical application of micromechanisms will make rapid progress in the 21st century. Much is expected from the creation, and goods with the achievement applied thereto, of advanced technologies whereinto non-lubrication, functional layer creation, and excellent heat conductivity are incorporated. It is quite significant that, since CD is available in any field as far as light-load low-speed sliding conditions are satisfied, sliding parts will be improved and service life will be prolonged.

This research and development project is aimed at development of the techniques which allow exploitation of manganese nodules occurring on deep sea bottoms (4,000 to 6,000 m deep) on a commercial scale, in order to secure stable supply of the non-ferrous metallic resource and improve general ocean development techniques. This project, established by the national project system, has been implemented cooperatively by the government, academic and industrial circles since 1981. Described herein are the interim results obtained by the FY 1984. The bases for development of the elementary techniques have been established for the comprehensive ocean tests. Bright prospects have been obtained to achieve the objectives, although there are some problems remaining to be solved. Interfaces between the sub-systems are being reviewed mainly by the persons in charge of the total system. No problem is foreseen in consistency of the individual components. The movement and exploitation functions of the test system are simulated and validated in detail, to develop the total system. It has been found by the simulations that the nodule-collecting machine shows nonlinear tracking characteristics (i.e., movement different from that of the exploitation ship), and unsteady movements (i.e., repeated movements of rapid starting and stopping).

For the contribution to elucidation of the geothermal structure in the Wasabizawa area, Akita Prefecture, survey by the paleomagnetic measurement and fracture system measurement was conducted of the borehole cores and specimens of outcrop granite obtained from boreholes of N6-WZ-3 and N6-WZ-4. In the survey, the following were carried out: measurement of the core fracture system of N6-WZ-3 (102-1,505m) and N6-WZ-4 (507-1,556m), paleomagnetic measurement of 9 outcrop granite specimens and 16 core specimens, and k/Ar age determination of 3 outcrop granite specimens. As a result of the paleomagnetic measurement of outcrop granite, the magnetization azimuth of the schistose granodiorite distributed in Kuwanosawa was regarded as almost NS. The measured magnetization azimuth of the core specimen obtained from the same rock mass was also made NS-based, and measurement of the fracture in the neighborhood was made. As a result, it was found out that the NNW system was dominant in dikes and that there was the NE system in most of the small geothermal channels. The fracture system of well tended to develop around the boundary between granite and metamorphic rock, and it was thought that this part could be a reservoir if temperature conditions are prepared.

Receiving subsidies from MITI, NEDO carried out this project in fiscal 1995 and 1996 as a joint research with Technology Research Association for Phosphoric Acid Fuel Cell Power Generation System and others. The project aimed at developing the accelerated test method which can evaluate in a short time the cell life of phosphoric acid fuel cells (PAFC) and the lowering of characteristics. The accelerated test method of PAFC life is thought to be a tool indispensable for the promotion of commercialization, but the accelerated test method like the usual material evaluation has not yet been established. To solve this problem, procedures were developed to rationally plan the accelerated test on short stacks of full scale based on the small cell test data. Here, to rationally estimate the operational state under actual conditions based on the data on the accelerated test, it is necessary to fully understand the mechanism of deterioration of PAFC. By conducting in parallel the element study for the basic elucidation of cell deterioration phenomena, obtained was the useful information/knowledge which back up the results of the accelerated test scientifically. 168 figs., 33 tabs.

Evaluation was conducted concerning R and D on magneto hydrodynamic (MHD) generation, with proposals made for the future R and D. As a result of the experimental operation and studies of the Mark 7 machine for MHD generation, a cold wall type generation channel was found promising in the long-term durability under MHD generation conditions. In addition, R and D was conducted on the exhaust gas control system that fulfilled an environmental standard, seed recovery method, grasp of seed coagulation state, etc. The R and D on element technologies were carried out along with the R and D of the Mark 7 and played a role in the backup of its experiment. MHD generation presents a large number of attractive characteristics, with its development expected in the future. However, it seems too early to immediately move on to the next step. Examinations should be made on such matters as comparisons with various kinds of new power generation systems using coal, trends in foreign countries particularly the U-500 project of the Soviet Union, the ideal system for more efficient development, and possibility of international cooperation.

It has been indicated possible in principle in recent years to measure biological molecular interactions with the molecules in the living state by combining the technologies called the co-focussing optical system and the fluorescence correlation spectroscopy (FCS). The FCS method is a method capable of analyzing concentrations, sizes, and inter-molecule interactions through detection of fluorescence fluctuation in single molecules in submicron zones. In spite of the FCS method being a very effective method to measure interactions in biological molecules, the technology has not reached a level that allows easy utilization under the present condition. The present research and development is intended to solve the technological problems in the FCS method in the co-focussing optical system, and perform as many research and development works as possible in a short time to establish a technological foundation that can be provided to bio-industrial and medical sites. Particularly, in order to make the utilization thereof possible in measuring biological molecular interactions in cells, a measuring technology using the bi-photon excited fluorescence correlation spectroscopy was established with an objective to reduce damages to cells and their internal micro organs, and minimize effects of interference signals from the own fluorescence.

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

In order to enhance the environment and wear resisting performance of the bearing mechanism for petroleum excavation bits assuming use at a depth of 6,000 m, discussions were given on a cubic boron nitride based ultra-hard thin film and a Ti{sub x}M{sub 1-x}N based hard thin film as the new materials. This paper describes the evaluation report for the year 2000. It was found that the promising material is the Ti{sub x}M{sub 1-x}N. The practical applicability test would require a considerable amount of expense and insurance fee, while putting the material into practical use would take some more time. However, the achievements in developing this new material will allow the material to be applied to cutting tools used under the same onerous condition, and theoretical development would be possible on the consideration of the film properties, whereas further development may be expected in the future. An international joint study has performed evaluations on the environmental resistance and the characteristics of the film at the University of Toronto. These evaluations are effective in enhancing further the properties of the thin film in the future. Achievements have been accumulated steadily from starting the fundamental studies, and high level objectives have been achieved. Accurate identification has been made on the state of developing the parts for petroleum excavation bits, with the objectives set properly. Putting the bits into practical use will still require public assistance. (NEDO)

Progress is reviewed for each of the subjects, and the findings are mentioned below. Research and development is progressing smoothly, specifications to be internationalized have been narrowed down, and it is now foreseen that the main points of the specifications to be presented will be successfully prepared. There are some subjects, however, about which it is difficult to specify to which technical committees they are to be submitted. Assistance, for instance supply of information, by technical committees involved is indispensable. The attitude toward international standardization taken by European and American business corporations visited for study by Japanese researchers is to be disseminated to Japanese business corporations since the information thus collected will help them. Although 75% of the 13 subjects have reached a level where they may be presented as specifications for international standardization, yet they need active support by organizations concerned and research of trends of internationalization-related institutions before they are actually accepted as international standards.

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)

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

This research and development project is aimed at commercialization of the light-aided instrumentation technology systems which safely, stably measure, transmit and control process information including image information, e.g., temperature, flow rates and components at large plants in industrial complexes, in the severe atmospheres in the presence of, e.g., electromagnetic induction and combustible gases. These optical systems need development of light transmitting/receiving devices, various optical devices that constitute the network nodes, and various types of sensors of improved functions and reliability, in addition to development of the techniques required for transmitting large quantities of information on a large scale. This project has attempted to systematically make break-through in the individual elementary techniques, in particular those in the widely diversified technological areas for the advanced devices, and thereby to expand the instrumentation/control technology frontiers. The results of studies on gallium/arsenic crystals, which are prerequisite for photoelectronic integrated circuits as the bases for the light application technology, and processes for producing thereof are highly rated worldwide. It is planned to effectively utilize the total system, constructed at then Nippon Mining's Mizushima Refinery, and thereby to establish the effective instrumentation techniques for commercial plants and to promote commercialization of these results.

This paper reports the achievements in fiscal 2000 in development of a technology to evaluate reliability of petroleum refining facilities. The development efforts were made mainly on analyses by simulation and neural net (NN) that utilize computers. In the high-temperature system facilities, the creep damage generation is governed by different factors including impurities. The evaluation on joint life requires simultaneous use of low temperature zone long-time test. Verification was made on application of non-destructive inspection, such as use of ultrasonic waves in the accelerated creep zone. Defect detecting capability was identified when an ultrasonic wave flaw detection model is used for buried piping. In the pulse eddy current flaw detection, a coil most superb in totality was selected by means of simulation, by which corrosion and wall thickness of piping and devices were detected from outside the sheathing materials. Development was made on a technology to diagnose and evaluate corrosion of tank in operation by using the AE method. The remaining life of transformers is determined by how seriously the coil insulating paper has been deteriorated, and furfural in the oil was found effective for the parameters. Particularly, application of the NN was revealed to be effective in estimating electric motor deterioration. A high-temperature sulfide corrosion rate estimating model was developed from the operation and measurement data of the facilities by applying the NN and TCBM. (NEDO)

In order to develop the evaluation methods for reappearing corrosion characteristics of coated steel sheets in a short time, acid rain composition and artificial acid rain composition for the accelerated test were studied, and the cyclic corrosion tests were conducted. The literature survey shows that the main ionic species present in acid rain are Ca{sup 2+}, Mg{sup 2+}, Na{sup +}, K{sup +}, NH{sub 4}{sup +}, SO{sub 4}{sup 2-}, NO{sub 3}{sup -}, and Cl{sup -}, of which the acid rain components are SO{sub 4}{sup 2-} and NO{sub 3}{sup -}, their equivalent ratio (NO{sub 3}{sup -}/ SO{sub 4}{sup 2-}) in the Far Eastern area being 0.2 to 0.3. Therefore, the solution specified by ASTM 1141 is diluted 30 times with water to prepare the base solution for the accelerated tests, where its acidity is adjusted with a mixed acid of NO{sub 3}{sup -}/ SO{sub 4}{sup 2-} = 0.2 to 0.3 (pH: 3.0 to 4.0). Two sets of preliminary cyclic corrosion tests were conducted, one involving acid rain spraying, drying and humidification in this order, and the other acid rain spraying, humidification and drying. Analysis of the test data indicates that difference between these test cycles in corrosion rate is within a deviation range caused by different testing tools. Therefore, the former condition is adopted as the basis for the accelerated tests, because of its smaller deviation caused by different testing tools. (NEDO)

High-temperature properties of glass melts, e.g., density, volume expansion coefficient, surface tension, viscosity, specific heat, thermal and electrical conductivity, redox equilibrium and gas solubility, are basic factors that must be considered in high quality glass melting technology and computer simulation of the glass tank furnace. The structure of the glass melts is also important for understanding these properties. This R and D program is aimed at proposing the international standards for the methods of measuring these high-temperature properties of the melts. The 1988 efforts are directed to the measuring technologies for density, volume expansion coefficient, surface tension, viscosity, specific heat, thermal and electrical conductivity, redox equilibrium, gas solubility and melt structures of soda-lime-silica glass melts. The R and D for measuring methods for high-temperature melts through international cooperation and establishment of the international standards for these methods are proposed in the joint CGR/HVG/TNO/GPF conference, which provides the arena for information exchange by glass manufacturers.

Technological development is in progress at present for the intelligent transport system for example that uses a microwave frequency range of 60GHz or 90GHz toward the practical use, with a demand increasing for measuring the electrical properties of fine ceramics (FC) to be used in the communication equipment of the system. The measuring method in the microwave frequency range of 30GHz or less is about to be standardized in IEC TC49/WG10; however, the method above 30GHz has not yet been examined for the standardization internationally. The subject research is intended to establish the method of measuring electrical properties such as the dielectric constant of FC for a high-frequency/ultra high-frequency wave range, dielectric loss and surface resistivity, to standardize the principle of their measuring methods, measuring tools, adjusting method of samples, procedures of measurement, etc., and to aim at the international standardization. This year, investigation and examination were carried out on various measuring methods including overseas examinations in the U.S., extracting the Fabry-Perot resonator method and a conductive cylindrical dielectric cavity resonator perturbation method for example, and evaluating the specifications of standard reference materials. In addition, a morphological technique was established for measuring sample surfaces affecting measurements, by means of an accurate measuring instrument for thin film surfaces. (NEDO)

The Wasabizawa area is located near the boundary between Yuzawa city south of Akita pref. and Ogachi-machi, Ogachi-gun, Akita pref, having a range of 3.0km northeast-southwest and 2.5km northwest-southeast of Wasabizawa almost as a center. The area for survey and its circumference are national forests, and the east and a part of the south of the area are designated as the Kurikoma quasi-national park third type special region. From the geochemical temperature distribution, it can be assumed that geothermal fluids of around 300{degree}C exist in the deep underground of the Kaminotai-Wasabizawa-Akinomiya area. From the distribution of density basements, the block structure of the basement can be estimated. Around the boundary of the ridge/sedimentation region of this density basement, fractures develop and the formation of reservoir structure is expected from the comparison with the result of the well survey. In the blowout test, obtained were 284.3{degree}C and 83.05 kgf/cm{sup 2} at a depth of 1,300m. In the geothermal system, it is assumed that reservoir structures of geothermal fluids develop in the deep underground of the central part of the area. The heat source to the geothermal system is supposed to be the magma reservoir remaining in Takamatsudake volcanic rocks. 110 refs., 177 figs., 105 tabs.

For development of emitters using diamond, important results have been obtained for the morphology, and cathode luminescence, Raman and photoluminescence spectra of polycrystalline diamond, synthesized by the vapor-phase process under varying conditions, on the electron radiation characteristics of the emitters. These results have led to clarification of the optimum vapor-phase synthesis conditions for diamond for high-function emitters. The techniques utilizing focused ion beams have also advanced to develop thin polycrystalline diamond films for emitters which correspond to the image elements of quality for television. For electron emitters, a structure prepared by implantation without using a high electrical field is proposed, and the device mechanisms involved are clarified. (NEDO)

The present Japan-China joint development project is intended to study liquefaction performance of different types of Chinese coals, select coal types suitable for coal liquefaction, and serve for enhancement in the coal liquefaction technologies employed by the Chinese side. Since a small continuous testing device has been installed in fiscal 1982 and begun with the trial operation in March 1983, the liquefaction test has been performed for about five years, and is scheduled to continue another three years. Chinese coals produced in seven provinces and two autonomous regions have been subjected to the coal type selection, on which discussions were given for liquefying reaction characteristics by using autoclave testing and small continuous testing devices. As a result, circulation tests were performed by the end of fiscal 1987 on five coal types, namely Beisu coal, Texgxian coal, Xianfeng coal, Shenmu coal, and Meihekou coal. Data were acquired during the circulation and at the equilibrium. Comparison of the results of tests on these five coal types with the results having been acquired from the 0.1-t/d BSU in Japan before modification verified the result being nearly reasonable.

This study was conducted to standardize the chemical analysis and non-destructive inspection methods for pure titanium metals of industrial grade. These methods are among those serving bases for international standardization of products. The chemical analysis is aimed at quantitative analysis of trace impurities, in particular, present in pure titanium metals of industrial grade by developing and standardizing the inductively coupled plasma atomic emission spectroscopy, known for its low detectable limit, and, at the same time, spark and glow discharged atomic emission spectrometry as the improved routine analysis methods. These methods, although being used by, e.g., steel makers, have not been standardized because the effects of titanium-peculiar matrix are not elucidated. The non-destructive testing is aimed at standardization of the techniques useful for automatic production lines. More concretely, these include optical methods aided by a laser or CCD camera for plate surface defect inspection, ultrasonic methods for plate internal defect inspection, and pressure differential methods for air-tightness of welded pipes. They have not been used yet for automatic production lines. (NEDO)

Full Text Available Sogo F Matlala Department of Public Health, University of Limpopo, Sovenga, South Africa Abstract: Pregnancy among secondary school students remains a public health problem and is associated with school dropout as well as poor maternal and child health outcomes. Schools in South Africa no longer expel pregnant students as was the case before 2000. Instead, the government encourages them to remain in class to complete their education, but pregnant students often face stigma, and some drop out of school as a result. To remain in class and access antenatal care, pregnant students require social support from teachers, parents and professional nurses. Unfortunately, teachers, parents and professional nurses support pregnant students on an ad hoc basis, and this calls for a model to facilitate collaborative social support. The purpose of this paper is to present and describe a model to facilitate collaborative social support for pregnant students attending secondary schools in South Africa, using the model description steps of Chinn and Kramer. The model is designed as a tool to enable pregnant students to remain in school, attend antenatal care and in the end, deliver healthy babies. The professional nurse, as a member and leader of the school health team which visits secondary schools to provide a package of school health services, is the agent or facilitator of the model. Keywords: communication, health team, learner pregnancy, maternal and child health, school health services, social network

Described herein are combined production systems, capable of flexibly, quickly producing diversified types of machine members in small quantities in an integrated manner from raw stock processing to assembling/inspection. Development of the related techniques, including those for development of lasers of high output, has been implemented in an integrated manner for development of optical members, processing techniques and so on. The techniques developed by this project are expected to be applicable to various industrial purposes, because of their high synergistic effects. There was no oscillator of high output, when the project was started. This project has reduced device size and cost and improved their reliability, greatly contributing to expanded use of lasers. The solid-state lasers have been developed, not only for growing large-size crystals but also for transmission of light. The automation guidelines for assembling and inspection steps, which heavily depended on manual works, have been drawn. The machining functions have been improved by incorporating the processing techniques aided by lasers of high or medium output. One of the major problems involved in the conventional system is very time-consuming works required for establishing the software for the computer by which it is aided for operation. This problem has been solved by providing the modular structure machines developed by this project with flexibility of machining machine. (NEDO)

Concerning the research and development of environmentally-friendly combustion technologies that had been conducted for six years beginning in 1992, analysis and discussion were made by a special committee dedicated to the evaluation of the efforts, and the outcome is stated. In the study of zeolite-base catalysts, a highly active catalyst was developed which assumes a multilayer structure of mordenite, etc., with titanium introduced thereinto using an NO-selective reducing catalyst. As for metal complex oxide-base catalysts, various catalysts high in activity were developed, based on saponite which is a laminar, clayey compound. As for alumina-base catalysts, details were learned of the reaction mechanism and catalysis activation sites and, helped by the findings, a silver-supporting alumina catalyst was produced. In the study of direct decomposition type NOx removing catalysts, a success was achieved in causing NO to be decomposed with high selectivity in an oxygen atmosphere by use of new-type electrodes, functional layers, and solid electrolytes. In the field of catalytic combustion, a PdO-Pt/Ba-Al2O3 catalyst was developed, which is to serve for a hybrid type catalytic combustion method. 19 refs., 112 figs., 25 tabs.

The paper described a study made during 1995 through 1998 on the application of 3D woven C/C composite materials to machine parts. The materials are large in rigidity, small in specific gravity, excellent in specific rigidity, and suitable for high speed rotation. They are excellent in heat resistance/dynamic reformation and expected as materials which can exceed limits of the existing steel for machine parts. However, to use them as machine parts, a possibility of high precision cutting is required. Therefore, a study was made on metal multi-layer membrane coating to C/C composites. Pitch-system high-elastic carbon fibers were made a 4-directional material by orienting horizontally in 3 directions at 120 degrees per plane and also orienting vertically. Various materials such as W, Mo and WC were coated by the laser assisted plasma hybrid spraying method. High adhesion coats with little pore were obtained. Multi-directionally woven C/C composites used to be poor in surface precision workability, but the problem was able to be solved by coating surfaces with metal layers and metal multi-layer membranes. The application is expanded not only to polygonal mirrors (for laser printing machine) and milling spindles, but largely to machine parts. 11 figs., 1 tab.

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 results achieved in fiscal 1992-1995 under the above-named project are stated. In the development of photocatalytic materials, a photocatalytic fluorocarbon polymer sheet suitable for use in a denitration apparatus is developed. A high density fluorocarbon polymer sheet composed of TiO{sub 2} modified with 0.3% of Pd/absorbent zeolite/fluorocarbon polymer PTFE (polytetrafluoroethylene) =48-63/24-36/10-20 is fabricated, which achieves a level higher than the denitration goal of 70%. Although the sheet in a 500-hour accelerated exposure test undergoes a hardening phenomenon in which elasticity decreases and tensile strength increases, yet degradation is hardly detected. Although a slight reduction is detected in denitration efficiency, yet it does not affect its practical application, and thus the durability goal is achieved. In the development of an energy conservation type air cleaning apparatus usable in underground parking areas or motorway tunnels, an apparatus capable of treating air at a rate of 2,000m{sup 3}/hour is fabricated, and this achieves a denitration level of not less than 80% in a field test (in the absence of rainfall). For denitration in the presence of rainfall, the apparatus is combined with an equimolar adsorption system, and a system capable of 80% denitration is proposed on the basis of data actually measured for each of the two. A conceptual design for a service model comprising a photodenitration and equimolar adsorption systems is evaluated, and it is found that it occupies less space than the existing models. (NEDO)

Three technical and business proposals for comprehensive analysis of the survey data for nationwide geothermal resources in Japan were submitted from three U.S. candidate contractor groups, whose evaluations were reported by the Republic Geothermal, Inc. The group comprising of the Aero Service and Golder Associates has few geological engineers, and their engineers related to physical exploration has no experience whatsoever in the geothermal field. The group comprising of the EG and G Corporation, Geometrics, Utah University Research Institute, Mars, and Republic Geothermal, Inc. requires a maximum amount of time and travel expense to adjust the implementations done by four companies. However, this is a group having the largest pan-world geothermal experience, and much experience about Kyushu area of Japan. The group comprising of QEB, Inc., Eureka, and GSC, Inc. requires considerable amount of time and travel expense because of the implementation performed by three companies. The group has some geothermal experience in America, but none whatsoever in Japan. Holding or not holding persons with geothermal experience is an important criterion in selecting the contractors.

At present, in oil refineries in Japan, the term of the continued operation in oil refining facilities is shorter than that in Europe and America because of the regulation on the open inspection period for boilers and hazardous material storage tanks. As a result, the refining cost is comparatively higher than in Europe and America due to the increase in inspection/repair cost and decrease in operational rate. Therefore, it is becoming important to effectively supply petroleum products by keeping stability in oil refining facilities of the whole Japan and prolonging the term of the continued operation of oil refining facilities, etc. In this R and D, the technical development is conducted which is needed for the long-term continued operation of oil refining facilities. The items for the R and D are as follows: assessment technology of reliability of oil refining high temperature system facilities, assessment technology of reliability of piping/storage facilities in oil refinery, assessment technology of reliability of oil refining power system facilities, technology of management support system in oil refining facilities. In this fiscal year, technical survey, data collection, and construction of the basic concept of developmental technology were mostly conducted. Also conducted were trial manufacture of various probes for non-fracture inspection use, oscillators, etc., and basic design of inspection equipment and trial manufacture of a part of them. And the data acquired were analyzed. (NEDO)

With the purpose of establishing fundamental technologies for ceramic porous materials that are excellent for artificial bone for a living body, evaluation technologies were developed for mechanical properties and biocompatibility, with fiscal 1999 results compiled. Performed for the examination of the mechanical properties were flexural test, compression test, tensile test, shearing test, torsion test, fatigue test, etc., with an evaluation testing method studied assuming that ceramic porous materials were applicable to implanting members. In the evaluation of biocompatibility, five kinds of osteoblast-like cell lines were cultured on a plastic disk and a dense hydroxyapatite disk, with adhesion and proliferation of the cells compared. Since these osteoblast-like cell lines adhere and proliferate on the surface and in the pore of hydroxyapatite, evaluation of the biocompatibility such as cell affinity was found possible with this in vitro method. With the view of obtaining principles for designing new bioactive ceramics, a method was developed for evaluating apatite-forming abilities of metal oxide gels having different compositions and structures in simulated body fluid.

By research groups having been sent, the integrated evaluation was made of the projects on the research cooperation with Indonesia in the development of environmental measurement use laser radar and the research cooperation with China in the mining waste water treatment technology using biology. As to the research cooperation with Indonesia, the purpose/target proposed were almost achieved, and all were favorably carried out. Especially, after finishing the project, the design/manufacture of an on-vehicle type Mie-scattering laser radar were made using the acquired laser technology. And, it was reported that an observation study of the state of air pollution in Bandung city was made using the laser radar. It can be said that generally the research cooperation with China was smoothly proceeded with. However, the Wushan mine is small in scale of management, and therefore, there might have been some points to be reviewed in selection of the mine for research. The pilot plant installed at the Wushan mine is not now operated. If the mine has strong management force, the effective use of the pilot plant after finishing the project might have been studied.

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)

This paper describes a hydrogen transportation system utilizing metal hydrides. For a storage method for moving, metal hydrides having high hydrogen containing performance like Mg-based hydrides would have high portability, less weight disadvantage, and high economic performance. In the fixed location storage, metal hydrides are superior in safety and maintenance cost to the conventional high-pressure gas holder and liquefied hydrogen storage. Because of their high dependence on equilibrium pressure and temperature, the significance of development thereof is large as the source of high-pressure hydrogen generation and motive force. More effective utilization of low-level heat, and separation and refining of hydrogen may also be expected. With regard to fuel supply for hydrogen fueled automobiles, metal hydrides are better in safety and total energy cost than liquefied hydrogen, but have a number of disadvantageous points in weight demerit. Eliminating the weight demerit would be the central issue of the development. Accompanying the development of hydrogen fueled automobiles, there are a number of technological elements to be developed on fuel supply system, such as storage, moving and transportation in hydrogen manufacturing sites, and filling and storage at using sites. Arranging the related infrastructures would be the issue. (NEDO)

An objective evaluation from a third party was conducted on the purpose, plan, execution method, achievement, etc. of a project 'The devilment of the catalyst surface high accuracy quantitative analysis technology using electron spectroscopy.' The purpose of the project is to make the relationing possible between the analytical results of the catalyst surface and the catalyst performance which has been so far difficult by heightening the accuracy of the catalyst quantitative surface analytical accuracy using the electron spectroscopy. The purpose and significance are judged to be worth a lot. This project is an industry/university/government joint project between the two countries. The project is excellent both in connection among research institutes and leadership of chief researchers, and it is judged that the joint research system fully functioned. The term of the project was shortened from 3 years in the first plan to 2 years, and therefore, the study was finished only on silicon oxide and organic thin films. However, it was determined that the study results are to be run in the magazine 'Surface and Interface Analysis,' which indicates that the achievement was judged to be very worth in the academic viewpoint.

This project is aimed at stable supply of the stocks for the petrochemical industry to cope with the keenly felt depletion of oil resources in the long run and price hikes, and promotion of effective utilization of high-sulfur heavy oil fractions difficult to desulfurize, thereby promoting prevention of pollution. The techniques have been developed to economically produce high-value products, e.g., olefins and aromatic hydrocarbons, by thermally cracking abundant stocks, e.g., vacuum residue. A 120 t/d fluidized bed pilot plant with coke as the heat medium was constructed to develop various techniques, e.g., those for controlling coking, decoking, quenching cracking products, and controlling coke particles as the heat medium, to realize stable, continuous operation for extended periods of at least 1,000 hours. The techniques have been also developed for effective utilization of heavy oils as by-products containing sulfur at high concentrations. Economic viability of the process is considered to be on a level with that associated with naphtha cracking at present, when an intermediate base vacuum residue is used as the stock material. It will be sufficiently competitive with naphtha cracking with all types of heavy oils as the stock materials, including intermediate base vacuum residue, in an intermediate term. (NEDO)

This paper summarizes the basic materials related to unified evaluation models for global warming. The unified evaluation is a disciplinary process to combine, interpret and share the information from different scientific disciplinary areas in such a form that the whole cause and effect chain can be evaluated from a macroscopic view. The process has higher utilization value than the evaluation overemphasizing a single academic area, and can provide decision makers with useful information. The process is suitable to model complex interactions and feedback mechanisms in diversified scenes such as climate change. The unified evaluation can identify the policy criteria along with a measure framework having consistency. The evaluation process is repetitive and continuous, wherein a science community can convey comprehensive knowledge and finding to a decision making community. In turn, the decision making side can feed back the experiences and achievements in learning. Execution of the evaluation requires different approaches, such as judgement of specialists including the modeling methods and experience, discovery as a result of applying the policies, and survey methods. The paper also describes the gaming conception, scenario analysis, and unification evaluation methods. (NEDO)

With connection to the clean development mechanism (CDM) taken into consideration, a study is made about achieving greenhouse gas reduction in Myanmar through power generation facility heat efficiency improvement and power loss reduction. Taken up in the study are the Shwedaung power plant, the Mann power plant, and the power transmission system in the Mandalay District. The profitability of thermoelectric power facility improvement is calculated using the financial internal rate of return (FIRR), derivable from the cost of thermoelectric power facility improvement and the convenience to be created thereby, and using the opportunity cost in Myanmar. The result is then subjected to a feasibility study. Most effective for CO2 reduction is the addition or installation of advanced compound cycle power generation facilities which are also excellent in heat efficiency and power generation cost. The FIRR of thermoelectric power facility improvement is 9.4-12.8%, which means the effort is worth investment. Measures for decreasing power loss during transmission include the use of higher voltages, laying of new lines, employment of conductors thicker in size, and the installation of phase modifiers. The economic internal rate of return (EIRR) and FIRR are calculated for the study of feasibility. An analysis covering a 10-year period results in a 20.41% EIRR (exceeding the socially accepted discount rate of 10%) and a 17.56% FIRR (exceeding the general loan interest of 15%), which means that there is feasibility.

The geothermal development promotion survey was conducted in the Akinomiya area, Ogachi county, Akita prefecture, and the FY 1998 results were summed up. In the surface survey, geology/electromagnetism/precision gravity survey was made as supplementary survey, and re-analysis of 3D models was made. In the well survey, three wells of N10-AY-6 to N10-AY-8 were drilled to conduct the core examination, temperature/pressure logging, sampler logging, short-term jetting test, etc. Also conducted were the reservoir evaluation, environmental effect survey, etc. by pressure monitoring and water level observation. The results of the comprehensive analysis predict the following. In the Akinomiya area, there exists heat source in deep parts around Mt. Yamabushi-dake and Mt. Takamatsu-dake; Being given heat from this heat source, rocks, ground water and volcanic gas react on each other to form geothermal fluids. It is presumed that high temperature geothermal reservoirs exist in the east of the area. Moreover, the pressure distribution indicates that the Akinomiya reservoir and Wasabizawa reservoir can be a chain hydraulically. On the other hand, the west of the area is the low temperature and heat conductive area, and therefore, there seem to be no high temperature fluids there. (NEDO)

As part of the geothermal development promotion survey, the comprehensive analysis was made on the survey of the existence amount of geothermal resource in the Akinomiya area, Ogachi town, Akita prefecture, which was conducted in FY 1999. In the evaluation of reservoirs, the following were carried out: comprehensive analysis of various data on the surface survey, well exploration, etc., which were stored in surveys from the primary to the forth, modification/construction of geothermal system models, numerical simulation using 3D models, etc. In the long-term jetting test, production/reduction tests were conducted using N9-AY-3 and N10-AY-8 as production wells and N8-AY-1 and N10-AY-6 as reduction wells. The results of the comprehensive analysis were outlined as follows. The distribution of high temperature zones promising as areas for geothermal development was grasped. The distribution of the main fracture structure underground was grasped. A total amount of 124t/h steam was confirmed by short/long term jetting tests. In the simulation of prediction of production, the result was obtained that there was potential power generation of 30MW in the Akinomiya area alone and 60MW both in the Akinomiya area and the Wasabizawa area.

A study is made about the feasibility of energy saving and CO2 reduction at the Citeureup Plant of the Indocement Company, Indonesia. Future embodiment of a clean development mechanism (CDM) is also discussed. Points examined for improvement involve air quenching clinker cooler (AQC) efficiency (mixing of raw materials, use of combustion control technology, and modification into a new type AQC); the finishing process (installation of a preliminary clinker crusher and a high-efficiency classifier); and waste heat cogeneration using AQC exhaust. The amount of energy to be saved will be 61,866 tons/year in oil, promising a 10.9% energy saving and CO2 reduction. The project requires a fund of 5,988,025,000 yen in total. The financial internal rate of return (FIRR) based on the environmental special yen credit is a little low, but the payout period of 11 years is reasonable. A similar result is obtained when export financing by the ex-Exim Bank is studied. A general loan is not proper in view of overall profitability. With precedents showing that it is near impossible for such a project to enjoy environmental special yen credit, it is necessary for the Japanese Government to build a CDM-oriented system under which environmental special yen credit will be offered to private sectors.

With the purpose of establishing fundamental technologies for ceramic porous materials that are excellent for artificial bone for a living body, evaluation technologies were developed for mechanical properties and biocompatibility, with fiscal 1999 results compiled. Performed for the examination of the mechanical properties were flexural test, compression test, tensile test, shearing test, torsion test, fatigue test, etc., with an evaluation testing method studied assuming that ceramic porous materials were applicable to implanting members. In the evaluation of biocompatibility, five kinds of osteoblast-like cell lines were cultured on a plastic disk and a dense hydroxyapatite disk, with adhesion and proliferation of the cells compared. Since these osteoblast-like cell lines adhere and proliferate on the surface and in the pore of hydroxyapatite, evaluation of the biocompatibility such as cell affinity was found possible with this in vitro method. With the view of obtaining principles for designing new bioactive ceramics, a method was developed for evaluating apatite-forming abilities of metal oxide gels having different compositions and structures in simulated body fluid.

Efforts are put into the study of direct iron making for use in a closed system where heat energy from a multi-purpose high-temperature gas furnace expected to be developed in the near future will be utilized for iron making. The researches, carried out for the establishment of technologies necessary for designing, building, and operating a pilot plant dimensionally suitable for connection to a 50MWt multi-purpose high-temperature gas furnace, cover the plant total system, a high-temperature heat exchanger, ultrahigh-temperature alloys, high-temperature insulating materials, a reduced gas generating unit, and a reduced iron making unit. When the effort is evaluated as a whole, it is found that the newly developed system is effective in preventing pollution, emitting but 0.1Nm{sup 3} of SOx per 1 ton of crude iron against the 0.4-0.9Nm{sup 3} emitted by a blast furnace/converter iron making mill. It is also found effective in reducing fossil fuel dependence and in enhancing energy source diversification. When it comes to energy conversion efficiency, furthermore, it is shown that the new system achieves a rate of 60% or more while only approximately 30% is attained by light water reactor power generation and approximately 40% by a high-temperature gas furnace.

The fiscal 1999 results of survey and research conducted for the establishment of solar cell performance evaluation and reliability evaluation methods are reported. In the development of a super high fidelity (broad spectrum) solar simulator for cell evaluation, a prototype was tested for performance evaluation, and initially set values were achieved. In the development of a large-area module evaluation technology, the radiation area was increased to be 1.0m times 1.0m large. Outdoor exposure tests continued at 5 sites in Japan, 3 sites in Australia, and 1 site in Oman, and analyses and databasing were carried out for the outputs of various types of solar cell modules. As for the problem of coloring of fillers which are module constituents, coloring in the U.S. was attributed to high temperature and intensive insolation, and in Austria to an oxidation inhibitor. In the development of a photo-accelerated degradation testing method for Si-based solar cells, application of the cycled illumination test was found feasible. In this test method, an amorphous silicon solar cell retains 70% of the initial Pmax value even after the passage of a period equivalent to 30 years. (NEDO)

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

Surveys and studies were conducted for establishing methods for evaluating solar cell performance and reliability. In the effort to develop basic technologies for the comprehensive evaluation of the performance of various types of solar cells and modules, an ultrahigh matching solar simulator and a large area solar simulator were built. The long-term exposure tests of solar cell modules kept on at 5 sites in Japan, 3 sites in Australia, and 1 site in Oman, and the databasing of the test data was planned. In the long-term evaluation of solar cell durability, investigations centered about module deterioration, where abnormal heat generation was observed, cause of increased resistance was inspected, and separation between the cell and the filler was examined. In the development of an accelerated photodegradation test method, it was found that the result of a light-dark cycle test with the ambient temperature varied agreed excellently with the results of outdoor exposure tests. It was consequently proved that the light-dark cycle test was a very promising candidate for an accelerated photodegradation test for a-Si solar cells. (NEDO)

The results of the second phase research and development project for developing the resin-based composite materials as the basic technologies of the next generation are evaluated. The second phase (FY 1983 to 1986) project is carried out to achieve the objectives, which are set up based on the objectives for the basic designs and the results of the first phase project. As a result, the concrete (promotion objectives), including those related to mechanical characteristics, have been almost achieved. For development of the highly functional FRP materials, the R and D efforts are directed to improvement of their moldability while satisfying the requirements of high functions, e.g., resistance to heat, leading to development of the basic techniques for epoxy resin-based intermediate materials. These results indicate possibility of commercialization of highly heat-resistant polyimde resin-based and novel resin-based intermediate materials. The results of the novel molding/processing methods, taken up in the second phase project as the ones which use no autoclave, are rated that they are developed to suggest possibility of the eventual commercialization, although the products they give are not always showing sufficient mechanical properties.

Described herein is development of direct steel-making using high-temperature reducing gas. A light hydrocarbon fraction (boiling point: 230 degrees C or lower), produced by steam cracking of vacuum residua, is reformed into a reducing gas in the presence of steam, using heat to be supplied by a nuclear plant which produces high-temperature gases for various purposes. This reducing gas is then supplied to a plant for producing reduced iron. This project has established basic techniques for designing, constructing and operating a direct steel-making pilot plant, to be connected to a 50 MWt high-temperature gas test furnace. The closed iron-making system and greatly reduced SOx emissions to several fractions of the current level are some of the expected effects. The environmental impacts of the high-temperature gas furnace will be on a level with those associated with a light-water reactor. Cracking and gasification of vacuum residua, which has found limited purposes so far, should expand its applicable areas and reduce dependence on fossil resources, leading to diversification of energy sources. The overall thermal efficiency of the high-temperature gas furnace is expected to increase to at least 60%, because its high-temperature gases of around 1,000 degrees C can be used for heating processes, and the waste heat can be further used for generation of steam for power production.

This paper describes the achievements in fiscal 1992 in the field tests on fuel cell power generation systems. The three locations subjected to the present analysis are all installed with 50-kW systems, whereas power generation efficiency of around 35% such as 35.3, 34.2 and 34.6% was obtained when the systems were operated at the rated output. When the load gets to below a certain load band (about 30 kW), the power generation efficiency decreases proportionately with the load. The overall efficiency including heat supply was 77.8, 70.7 and 80.3% respectively at about the rated output, showing a trend that the higher the thermal efficiency, the higher the overall efficiency. The case of generating both electric power and heat simultaneously has higher efficiency than the case of heat supply alone. The contribution rate of the fuel cell as a base load was 2.8, 4.6 and 13.6%, respectively. The system with as high value as 13.6% takes a power load following type operation mode, in which power is generated during a time band with large load during weekdays, and no power is generated at nighttime and in holidays when load is smaller, playing a role of peak responding power supply. Only one trouble has occurred in an auxiliary generator in the heat recovery system. (NEDO)

Geological structure analysis maps and lineament maps were prepared on the north-eastern area and parts of the ancillary areas thereof by analyzing radar images of a 1 to 200,000 scale. With regard to the geological structures, analyses were performed by using as the original data the north look radar images for the three special geothermal areas to have prepared the geological structure analysis maps. The analysis of the radar images identified ground bed boundary lines in more detail than in the existing geological maps, and new discoveries were made available on faults. The lineament maps were compiled by implanting into respectively corresponding topographic maps the 24 N-S lineament maps made by the west look radar images for the whole surveyed areas, and the 16 E-W lineament maps made by the north look radar images for the special geothermal areas. Based on the clarity and characteristics deciphered on the images, the lineaments were classified into the major, minor, and subtle lineaments, which were indicated on the lineament maps. The lineaments were digitized by positions of the edge points, and the histograms and statistical tables were prepared by computer processing. (NEDO)

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

Assessment and examination were conducted on the scientific/technological aspect, environmental aspect and economic/social aspect concerning measures for mitigating climate change, as a part of international cooperation in global warming issues. In the development of assessment methods for cost analysis, it revealed that, in the activities for mitigating emission of greenhouse effect gases (GHG) or for increasing carbon sequestration, benefits of the mitigation sometimes surpassed their cost, allowing the society to benefit from the mitigation. In the examination of problems in technology transfer and their solutions, it was found that, in order to attain successful transfer, partnership among the parties interested was essential and that each government was capable of promoting such partnership. In the assessment of various policy options, the situation in the U.S. is such that the market aspect of GHG emission permit and credit trading is rather weak because of immaturity in a legal framework on GHG emission trading and because of undefinedness in the systems of the Kyoto Protocol and in the possibility of its validation. However, the reason enterprises are actively participating in the early market is that they plan a risk-hedge for example in anticipation of tighter regulations in the future. (NEDO)

The concept of Japanese type demand analysis model (end-use model) was constructed for the efficient management of electric power companies and efficient power utilization. Diffusion and use conditions of domestic air conditioners are considerably different depending on local life style and climate. In order to design demand measures considering combination of appliances in every market segment, demands in an end use level (end demand level, each appliance level) should be acquired. The basic structure of the model is composed of various exogenous variables such as weather data, price and ups and downs trend of customers, and various appliance data such as size, efficiency and energy consumption rate, and various customer data such as possession rate of appliances and number of customers. The final energy demand is estimated by integrating the above variables. By systematizing the stored data of precise actual load conditions, construction of DSM (demand side management) strategy becomes possible by using computer tools. 8 refs., 15 figs., 13 tabs.

As a part of the evaluation of landscape of civil engineering structures, a method was studied for quantitative evaluation of surface color and color hue of the exposed concrete. The surface colors of concrete structures constructed at more than one sites were measured using a colorimeter and were statistically processed. The colorimeter can measure colors by irradiating the standard light onto the surface of the object and dividing the reflection light into ingredients, lightness L and color phase a and b in the CIELAB equal color space. The L/a/b measuring data were plotted which were obtained from 2010 measuring surfaces of 49 structures at 7 construction sites. As for the surface color of concrete, it was found that ingredient L measured by the colorimeter reacts on variations of color very sensitively and agrees well with the trend of evaluation by eyes. Namely, human being senses the difference of concrete color mainly from the difference in lightness and senses the difference as the color hue. Further, using the neural network, an evaluation method was established which was the same as the human sense. 1 ref., 8 figs., 3 tabs.

This paper describes comprehensive evaluation and analysis mainly on the 51 items adopted in the high-performance industrial furnace introduction field tests. The development of a high-performance industrial furnace has completed the fundamental development research in fiscal 1998, and the possibility was verified on energy saving of more than 30% and reduction of NOx emission by 50% over that by conventional furnaces. Upon this fundamental achievement, the field test project has started as the comprehensive approach to developing the practically usable technologies for three years from fiscal 1998 until fiscal 2000, which is being promoted as a joint research project. According to the survey on the actual state in fiscal 1998, a little less than 20,000 industrial furnaces having combustion capacity of more than 500,000 Kcal/hr (excepting boilers) are being used. If these furnaces are converted into the high-performance industrial furnace, energy conservation of 210,000 x 10{sup 6} Mcal (converted to crude oil of 22.7 x 10{sup 6} kl/year) can be achieved from the maximum annual energy consumption of 700,000 x 10{sup 6} Mcal (converted to crude oil of 75.7 x 10{sup 6} kl/year). This conservation amount corresponds to about 12% of the final energy consumption in the whole Japanese industrial departments in fiscal 1996. It is expected that the performance of the full-size high-performance industrial furnace will be verified, and this technology will be promoted for wide proliferation. (NEDO)

Discussions and evaluations have been performed on the safety and durability of the device installed with inverter to protect grid connection being an important device in the photovoltaic power generation system. This paper summarizes the achievements in fiscal 1996. The current fiscal year performed data collection and long-term continuous operation according to the durability test program for the device installed with inverter to protect grid connection, as the continuation from the previous fiscal year. In the electrical characteristics, although no large changes have been found in AC overvoltage and AC undervoltage, instability was observed in the detection level. With regard to temperatures in different components, the temperature rise has become nearly the same as in the maximum output continuous operation as a result of the repetition of the operation and shutdown, whereas the influence on the electrical and thermal stresses have increased. Particularly, when temperature rise in the AC side noise filter was given observation, the measurement of conductive high-frequency terminal voltage showed a value higher by several ten dB than in the previous fiscal year. The current fiscal year has gone farther to starting the measurement of noise electric field intensity as the base of electromagnetic interference. (NEDO)

Discussions and evaluations have been performed on the safety and durability of the device installed with inverter to protect grid connection being an important device in the photovoltaic power generation system. In discussing the durability test items, electrical property changes were observed on AC overvoltage, AC undervoltage, frequency rise, and frequency fall, as the continuation from the previous fiscal year, in order to evaluate temperature rise in different parts due to lapse of operation time and the effects of thermal stress in each component on the stress of the entire product. Furthermore, verification of single operation detecting function, tests on sudden input power change, sudden grid voltage change, and measurement of conductive high frequency terminal voltage were conducted in addition to the above observations. In discussing the durability test methods, repetition of operation and shutdown during the rated operation was adopted in place of the simulated operation using variation in the insolation having been discussed in the previous year. As a result of the tests, no noticeable changes were recognized from the evaluation result after a lapse of 5,000 hours from the start of the operation, as compared to those after the aging operation.

Tests and discussions have been performed on the safety and durability of the device installed with inverter to protect grid connection, being an important device in the photovoltaic power generation system. The particularly important requirements demanded in the device were specified as maintenance of electric power quality, coordination with the protection system in the grid side, and assurance of safety of personnel and facilities. The current fiscal year has performed operation corresponding to that in the actual field for 20 years in total, and the evaluation tests on electrical characteristics and electric power quality. This paper summarizes the achievements in four years including the results available up to the previous fiscal year. Although no large change has been identified in the electrical characteristics, variance has been found in the detection time of overvoltage in the grid side. With regard to the electric power quality, the value has exceeded 89 dB as the determining condition for the certification test in the conduction interfering waves of 5 kHz to 10 kHz. In addition, it was confirmed that the conductive high-frequency noise terminal voltage in the grid side after the repetition of operations and shutdowns tends to increase according to the operation lapse time.

For the purpose of evaluating the efficiency of fuel cell including the fuel supply system, survey was made of drilling of gas resource, conversion to liquid base fuel, transportation, storage, etc., the energy conversion efficiency was studied considering reforming characteristics of various fuels. In the comparison between LNG, methanol, DME and GTL that originate in natural gas and LPG and naphtha that originate in oil, a big difference is that methanol, DME and GTL were made through the conversion process with the large energy consumption. Namely, by the time before the reforming into hydrogen, the oil base indicated a higher efficiency in secondary energy fuel production than the natural gas base. Further, the reforming efficiency is the highest in methanol and DME, and there is a little difference between the integrated fuel cell (normal pressure) and the hydrogen production use fuel cell (pressurized). Concerning city gas and GTL, the efficiency is lower, affected by S/C. The overall efficiency is determined considering the conversion efficiency in other stages since it is determined by the conversion efficiency of up to the raw fuel and the energy conversion efficiency at PEFC.

With an objective of promoting the international standardization efficiently and strategically, surveys were performed on trends of international standardization in Europe and America, and researches on means for the international standardization. The standards strategy in the U.S. is to increase the U.S. competitive power in overseas countries, support strongly the domestic markets, and at the same time, deal with problems such as those of the environment. It attempts to structure a framework that can be utilized by any concerned parties, including business entities, the government, and consumers, whereas the National Standards Strategy (NSS) has proposed the initiative. In Europe, targeting to establish international standards originated from Europe, works are becoming more active for new technologies such as information communicating technologies from the R and D phase to the test and evaluation methods, taking the standardization into consideration. These works are being carried out within the scope of the common EU R and D, represented by the 'Framework program' and the 'EUREKA program'. In the survey and research on means to complete the international standardization, analyses and surveys were performed on the latest information, such as TC/SC, which are scheduled of proposition. Advices were given on giving the directionality and establishing the strategy. (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)

Ultrahigh-speed electronic technology is indispensable for creating industrial basic technologies supporting the advanced information society in the 21st century. Control technology of photonic and electronic states in a femtosecond region is essential. To establish the development policy of generation and transmission devices for femtosecond light pulses, research and analysis were made on nonlinear optical response and light pulse transmission properties. Basic issues on devices and materials such as mode-locked semiconductor laser, pulse compression device and light-light modulation material for coding were extracted. For new femtosecond light pulse control/distribution devices, research and analysis were made on response properties of intersubband transition phenomena in a semiconductor and electron spin relaxation phenomena, and semiconductor quantum structure. To develop metrological technology using ultra-short light pulse, study was made on an evaluation method for time- fluctuation of pulses in 100 femtosecond level. Generation of femtosecond high-intensity X-ray pulse was possible by fine control of the existing high-intensity laser. 19 refs., 26 figs., 1 tab.

With an objective of promoting the international standardization efficiently and strategically, surveys were performed on trends of international standardization in Europe and America, and researches on means for the international standardization. The standards strategy in the U.S. is to increase the U.S. competitive power in overseas countries, support strongly the domestic markets, and at the same time, deal with problems such as those of the environment. It attempts to structure a framework that can be utilized by any concerned parties, including business entities, the government, and consumers, whereas the National Standards Strategy (NSS) has proposed the initiative. In Europe, targeting to establish international standards originated from Europe, works are becoming more active for new technologies such as information communicating technologies from the R and D phase to the test and evaluation methods, taking the standardization into consideration. These works are being carried out within the scope of the common EU R and D, represented by the 'Framework program' and the 'EUREKA program'. In the survey and research on means to complete the international standardization, analyses and surveys were performed on the latest information, such as TC/SC, which are scheduled of proposition. Advices were given on giving the directionality and establishing the strategy. (NEDO)

Discussions and deliberations were given by the comprehensive survey committee on standardization of a total gene inspection system from specimen adjustment necessary for the gene inspection system to data processing. This paper summarizes the achievements in fiscal 2000. In standardization related to the specimen procedure and the inspection technique, the specimen storing method and the report statement contents were established. In addition, verification was made on the heat-resistant enzyme reagent and such measuring devices as the electric migration device and the photographing device. Discussions were given on standard substances used in the gene inspection. Regarding the K562 cell strain, cross-checking was performed in three institutions, wherein discussions were given on interchangeability of the inspection results, and the usefulness of the K562 cell as a standard substance. As a result, all the three institutions have come to an agreement on the Southern method, the FISH method and the RT-PCR method, but not on the real-time PT-PCR method, leaving the subject as the future assignment. In the survey for Europe and America, visits were made to AFNOR, CEN, DIN, FDA and CAP for the attempt of collecting information and establishing international exchange. (NEDO)

For the purpose of evaluating the basic characteristics of high-temperature superconducting magnetic bearings (SBM), a system model is designed, experimentally manufactured and tested, which is embodied in the design/evaluation of a large-scale system, with an investigation carried out for the introduction of the system into an electrical power system. In this framework, an examination and research were conducted for the system design technology on which each component technology in the system structure can be applied consistently in the system. In the comparative assessment of various flywheel power storage systems, the specifications and achievements were compared in the component elements of the flywheel systems developed in Europe, America and Japan through the literature studies and the field survey, with examination performed towards the future development. As a result, it was found that, in America, bearings were all SMB's without control. Boeing's objective for the development is 10kWh or so in view of convenience for transportation and is prone to arrange it in numbers. Further, investigations were made in literature and documents on the domestic and international trend of development of high-temperature superconducting flywheel systems, elucidating the details of the development.

Described herein are the FY 2000 results of the research and development of the fatigue characteristics of the bioceramics, fatigue and impact-resistance characteristics of the members of these materials, and methods of evaluating their compatibility with a living body, for proposing the international standards. The test results of alumina and zirconia as the bioceramics indicate that their bending fatigue characteristics greatly depend on environmental conditions and frequency, suggesting necessity for the evaluation in the environments which simulate the living body inside. The compression and impact tests are conducted for the artificial femoral heads with a taper. It is found that the simulated body fluid, having the dissociated ion concentration adjusted at the level in the human blood plasma, remains unchanged in the concentration at 36.5 degrees C for 4 weeks; the ion concentration is unaffected by filtration with the aid of the microfilter useful for, e.g., removal of bacteria; and the synthetic apatite has almost the same composition as that for the bones in a living body. It is also suggested that activity of the bioactive ceramics can be evaluated by their ability for forming apatite in the simulated body fluid. (NEDO)

This paper describes interactions between wall rocks around magma and hot water. The paper discusses effects of hydrothermal environments on dynamic properties of rock minerals with respect to hydrolytic weakening (decrease in dynamic strength of a mineral under presence of water) and reaction enhanced deformation (deformation accelerated by chemical change occurring in a mineral itself). It also explains chemical reactivity of minerals under hydrothermal enviroments with respect to four types of chemical changes in minerals, factors governing mineral dissolution rates, and importance of equilibrium and non-equilibrium in main components in reactions between minerals and waters. These statements quote mainly results of indoor experiments. The paper indicates the following matters as problems to be discussed on interactions between wall rocks around intrusive rocks and hot waters: Deviation from chemical equilibrium in reactions between rocks and waters; change in permeability as a result of reactions between rocks and waters; and possibilities of hydrolytic weakening in rocks around intrusive rock bodies. 52 refs., 6 figs.

Described herein are results of evaluation of the developed excavators remotely controlled for highly deep submarine oil fields. The excavator system was designed to work at the target water depth of 200 to 250 m and excavation depth of 8,000 to 9,000 m, though not quite satisfactorily. There were several practical problems to be solved, e.g., those found in accuracy of reentry in the excavated section, cables connecting the driving equipment to the excavated section, and entangled hoses. The works were divided and system was configured in an attempt to secure all-weather type serviceability and to improve economic viability. The other major works included attempts to improve equipment functions and reduce manpower cost. Nevertheless, however, the construction cost was considered to be higher than expected, and no firm prospect was obtained whether the new excavator system was economically competitive with the conventional rig. The factors that pushed up the construction cost were various facilities needed by the new system with the separated excavation and driving sections, e.g., those facilities for helping the system land on the sea bottoms, material supply/storage facilities, and automated/unmanned facilities. The system failure and other items related to reliability are no clearly understood, making it difficult to compare it with the conventional rig in service factor. It was not adequate, therefore, to advance the next R and D phase as planned, and decided that the project was suspended to see the world development trends, because the clear plans for the future could not be drawn at that time.

The program for narrowing the spectral lines for semiconductor lasers experimentally confirms validity of the external resonator structure with the diffraction lattice. The program for the developmental research on spectral width meter designs the width meter based on the delayed self-heterodyne technique, because of necessity for measurement of the spectral line width at a resolution of several hundreds Hz or less. The program for the saturation spectroscopy of iodine molecule designs and fabricates the iodine cell, to lock the semiconductor laser wavelength on the specific absorption line of iodine. It is judged, based on the test results, to be rational to adopt the absorption line of the (6-3) transitional P33 superfine structure. The program for the developmental research on wavelength meter conducts the preliminary tests for atmospheric pressure, temperature and humidity changes as the parameters which affect the measurement accuracy.

Tests and researches have been performed with the objectives to establish an evaluation technology for load leveling effect by using a small photovoltaic power generation system for residential use, to clarify the effectiveness of the system as a discrete power supply source through demonstration operation, and furthermore to achieve optimization of designs of the small photovoltaic power generation system for residential use. This paper summarizes the achievements in fiscal 1997. The current fiscal year has performed the continued collection of data of the demonstration operation, and analysis and evaluation on the photovoltaic power generation characteristics and the house load characteristics. According to the data analysis result for fiscals 1995 through 1997, it was shown that, although the photovoltaic power generation system for residential use does not contribute much to load leveling in a house, it contributes to load leveling in the distribution line on the whole or a case as large as a grid. In addition, according to the survey on users who have installed the photovoltaic power generation system, it was indicated that the consciousness of electric power and energy conservation has heightened. The capacity of a photovoltaic power generation system for residential use is 3 kW for a standard type of home, which can take care of more than 60% of the house load. It was concluded that, if a storage battery of small capacity is accommodated, the system is effective for reduction of momentary peak load, enhancement of the power quality, and supply of power at a disaster.

A survey was carried out to identify the evaluation by British Industry on COP3 and the nation's future activities. In Britain, the gas emission level in 2000 is estimated to achieve sufficiently the initial target as the level is lower by 4 to 8% than that in 1990. This is largely attributable to substitution of coal by natural gas. At the Kyoto Conference, the European Union agreed with its target to reduce the emission of greenhouse effect gas over the period 2008-2012 to 8% below its 1990 level. Britain agreed to share its reduction rate at 12.5%. The Labour Party had set an election pledge since before the general election to reduce carbon oxide emission by 20% (against the 1990 level) by 2010, and the Prime Minister Tony Blair has also confirmed his commitment to this target. The policy making work to achieve the COP3 target has begun in 1998 when the UK Climate Change Program (consultation paper) was issued, and will continue until February 1999. The Advisory Committee of Business and Environment representing British Industry has already published their advice on how to achieve Britain's COP3 objective, which are considered by the government in the above mentioned paper.

For the purpose of achieving the target of reduction in CO2 regarded as substance causing global warming which was agreed at COP3, the study has been made since FY 1993 on 'the development of high performance industrial furnaces (regenerative combustion furnace using heat storage type burner for realization of high temperature air combustion).' By applying the good results obtained, a field test project for introduction of high performance industrial furnace has been implemented for three years (FY 1998 - FY 2000) to confirm the actual performance, reliability, etc. Collection/arrangement were made mainly of the data obtained in this field test project for the introduction of high performance industrial furnaces in each fiscal year (1998, 1999 and 2000), and verification/evaluation and arrangement were made. In this R and D, energy conservation was achieved at a rate of more than 30% of the target. Also about NOx, the result was obtained that the NOx by energy saving can be reduced 50% in almost all kinds of furnace if adding the reduction amount in emission amount and the reduction amount by high temperature air combustion. About the quality, the good result was obtained. Downsizing was conducted in approximately 10 examples. (NEDO)

Studies are conducted to establish the methods of testing and evaluating applicability of ceramic-metal bonding for ceramic gas turbines, and the FY 1993 results are reported. The program involves measurement of residual stress by the X-ray method and durability tests for the joints of silicon nitride and austenitic stainless steel with copper as the intermediate layer, and analysis and classification of the strength/durability test results obtained until the previous fiscal year by the finite element method, to evaluate applicability of the joining. For the strength characteristics at high temperature, the test pieces tend to lose strength at 400 degrees C and higher, and high-temperature strength as cross-head displacement speed increases. The upper limit of bending strength at room temperature decreases as number of thermal cycles increases. The test pieces subjected to thermal cycles have a higher bending strength at high temperature than at room temperature. The results of the two-dimensional plasticity analysis of the residual stress in the joint by the finite element method are in good agreement with the results by the X-ray method. (NEDO)

This paper summarizes the achievements in fiscal 1996. The current fiscal year has performed collection of data of the demonstration operation, checked the consistency in photovoltaic power generation characteristics, and housing and distribution line load characteristics, and the results were mounted on the database. The demonstration operation data were used to analyze and evaluate the facility utilization rate in the photovoltaic power generation, photovoltaic power generation dependence of the house load, load rate, and peak load reduction rate. As a result, it was found that not much of the peak load reduction effect by the photovoltaic power generation was recognized because the house load is related mainly on lighting load. However, as seen from the distribution line load, the peak load reduction was recognized when the house load and the commercial and industrial load are mixed, whereas it was revealed that the reduction effect is worth evaluation.

Since the CO{sub 2} emission reduction cost is high under the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) rulings, they have made it clear that they will positively resort to the flexibility mechanism. This is to reserve a room for freely selecting power generation methods other than nuclear technologies with their nuclear power plants scheduled for renovation in the neighborhood of 2010. But the industrial circles are slow in responding, failing to accept the carbon fund concept. As for measures for greenhouse gas emissions reduction, since they depend on energy saving for their success, the response specially of the transportation division will be the key. In the industrial division, success depends on a voluntary consensus among industries that consume much energy. As steps to economize the trend of people's energy consumption, an energy tax and environmental tax are scheduled to be imposed. An overall program for greenhouse gas emission reduction is being drafted by a government committee, with the outline to be made known in May 1999 for finalization in autumn the same year. A power market liberalization bill has already been prepared, and a decision will soon be made on a plan for the second phase targets.

This paper summarizes the achievements in fiscal 1995. With the demonstration operation in the current fiscal year, through-the-year data have been accumulated for the first time since the start of the demonstration operation, and were mounted on the load leveling database. As a result of analyzing the demonstration operation data, the following points were revealed: regarding the housing load, the lighting load is the main factor both in summer and winter; the effect of reducing the peak load by photovoltaic power generation is recognized at about 60% as maximum, but the substantial effect has large variation, hence stochastic; and the reverse current becomes the main factor during daytime, not necessarily leading to improvement of the housing load characteristics in the aspect of load rate. According to the surveys on the energy demand trends up to the year 2030, the power supply configuration, and introduction cost, it was revealed that the photovoltaic power generation can be sufficiently expected as a power supply to handle the peak load.

The paper described the results of the FY 1998 WE-NET project survey. WE-NET is composed of various element technologies such as hydrogen production, hydrogen transportation, storage technology, low-temperature materials, hydrogen utilization, and hydrogen combustion turbine technology. Therefore, considering the effectiveness as a total system, it is extremely important to traversally evaluate the situation of the R and D of each technology and developmental achievements and to work out developmental plans with integration, considering the effectiveness as a total system. From viewpoints of making effective promotion of the project and attempting optimization as a total system, it is necessary to make organic/comprehensive connection and adjustment among individual subtasks all the time. In this survey/research, in the case of proceeding with the above-mentioned studies, a committee having knowledgeable persons and learned persons as members was established. There, an investigational study was conducted over the whole WE-NET structural technology, and at the same time the following were attempted: the constant/mobile comprehensive adjustment of the whole project, evaluation of the developmental results, and optimization of the developmental plans. The results obtained in 6 years of Period I were evaluated traversally and comprehensively, and how to proceed with the development in Period II was proposed, which showed the developmental continuity.

Weatherability tests have been performed on devices used in the residential photovoltaic power generation system by means of exposure, with the objectives to analyze and evaluate the safety and reliability due to aging of the devices used in the residential photovoltaic power generation system. This paper summarizes the achievements in fiscal 1995. In the outdoor exposure test on solar cell modules, multi-crystalline silicon solar cell modules were selected as the test specimens, and thermo-couples were embedded in the modules to measure the temperatures. Also for the purpose of comparison, storage test specimens were stored in a constant temperature and humidity chamber. The exposure tests were carried out in three locations of the city of Choshi in Chiba Prefecture, the Miyako Island test site in Okinawa Prefecture, and the Miyako Island seashore. In the measurement and evaluation, appearance observation and measurements of output characteristics and insulation resistance were executed in summer and winter. No noticeable changes were observed in the measurements after lapse of four months and six months. In the outdoor exposure tests of metal test pieces, aluminum alloys were tested for corrosion caused by contact with different kinds of metals. Although the test period was short in the current fiscal year, difference in corrosion degrees in the aluminum alloys was found already in three months. (NEDO)

Weatherability tests have been performed on devices used in the residential photovoltaic power generation system by means of exposure, with the objectives to analyze and evaluate the safety and reliability due to aging of the devices used in the residential photovoltaic power generation system. This paper summarizes the achievements in fiscal 1996. In the outdoor exposure tests on solar cell modules, results of the tests were derived for up to 18 months after the start of the exposure at Choshi City, Miyako Island and the Miyako Island seashore. In the appearance observation, some white rust has appeared in the contact section of the aluminum frames of the solar cell modules and fixing screws, which have been exposed at Miyako Island and the Miyako Island seashore, but no changes that may give influence on the performance of the solar cells have been observed. The results showed performance similar to or slightly inferior to that before the exposure as a whole. The insulation resistances were all found good. According to the result of the outdoor exposure test of metal test pieces, noticeable difference in the corrosion degrees was recognized in the contact corrosion section of the aluminum alloys exposed in three areas having different meteorological and environmental factors. Electroplated zinc was found to have severer pitting corrosion in the contact sections than treatment-free zinc. (NEDO)

With the objectives to analyze and evaluate the safety and reliability due to aging of the devices used in the residential photovoltaic power generation system, weatherability tests have been performed on devices used in the residential photovoltaic power generation system by means of exposure. This paper summarizes the achievements in fiscal 1997. In the outdoor exposure tests on multi-crystalline silicon solar cell modules at Choshi City, Miyako Island and the Miyako Island seashore, the output characteristics after the exposure tests showed a result that the insolation intensity and the change in the short circuit current are approximately proportional, and the temperature in the module and the change in the open voltage are inversely proportional. The module characteristics retention rate showed no change in the 29-month exposure at all of the three exposure locations. The insulation resistance in the exposure test specimens have been good at 2,000 M{omega} or more in all the locations until 18 months have elapsed. However, the test specimens in Miyako Island and the Miyako Island seashore showed 99 M{omega} after 23 months, and 129 to 1,774 M{omega} after 29 months. According to the outdoor exposure tests of metal test pieces, noticeable difference was found in corrosion due to difference in the environment by each exposure location, whose order of the corrosion degree was the Miyako Island seashore > Miyako Island > Choshi City.

In the research and development of photovoltaic power generation system evaluation technology, great progress has been achieved in performance improvement and cost reduction as far as constituent devices such as power modules and inverters are concerned. In the designing of systems, however, quantitative elucidation of loss and power reduction factors remains insufficient. Under the circumstances, several types of photovoltaic power generation systems expected to be put to practical application in the future are taken up, test facilities are constructed which simulate them, and data are collected. The thus-collected data are utilized for research and development of evaluation techniques necessary for the improvement of photovoltaic system efficiency, such as design parameter quantification, databasing and utilization thereof, and simulation technologies, for the establishment of technologies for optimum designs and optimum operations. The data book accommodates data, arranged in an easy-to-use fashion, collected about verification test facility (interconnected systems, independent systems, and water pump systems) operation, weather conditions, and residential photovoltaic power generation systems.

For encouraging the promotion of international standardization involving the six subjects of advanced technology taken up under the above-named project, wide-range investigations are conducted into measures for international standardization, the activities of international standardizing agencies and organizations, and the approaches of European and American business corporations to this issue. Technical literature and material are studied in Japan, and interviews are held overseas with responsible persons at organizations and corporations engaged in this task. At Standards Development Organization (SDO) of America, verification tests are under way for early development into international standards of technical standards it has so far developed independently. For the strategical utilization of intellectual property incorporated into its technical standards, SDO accepts that the best policy is to win approvals from patent proprietors at the early stage of standardization process by presenting them with conditions about patent implementation. In Europe and America, for the enhancement of their competitive power in the international theater, governments and civil sectors cooperate with each other for the establishment of international standards and, in business corporations, the management takes the initiative in coping with the issue with an understanding that there are business opportunities in international standardization.

This paper summarizes the result of a survey for promotion of geothermal development and an overall analysis of the Akinomiya area in fiscal 1996. The subject area is located in Katsuo Town in south of Akita Prefecture. The geothermal reservoirs are regulated by the irregular construction created by upheaval and subsidence of the pre-Tertiary basement rocks. The underground temperature construction shows the temperatures rising toward Mt. Yamabushi. The latest geothermal activities should have taken place after the eruption of Mt. Takamatsu. The geothermal activities near the Arayu area have been most active until recently, and is still predominant. Transformation activities were active in the former period of the Pleistocene era. The acidic transformation band has been active after sedimentation of andesites in Mt. Takamatsu thereafter, which should have been active not only in areas where it is now active on the ground surface, but also in greatly wider areas. Geothermal fluid flows being regulated by faults, whereas fractures with high permeability existing along the faults are suitable for developing steam collection. Hot spring waters were produced by the geothermal fluid having risen along the faults and been mixed with and diluted by ground surface water near the ground surface. Areas promising for geothermal development would spread over the areas with high permeability along structural lines such as faults which show the convection type temperature pattern and temperatures higher than 250 degrees C.

This paper explains the concept, history, and analytic methods of life cycle assessment (LCA), showing its application to beer bottles and cement factories as specific examples. The LCA is a method to calculate substances and energies put into the whole process of production of a product from raw material mining to product wasting and environmental loads emitted therefrom. It also evaluates the result collectively and quantitatively. A first case of the research is reportedly the one performed at Coca-Cola Co., Ltd. in 1969. Full-scale researches have gone forward in European countries in the recent several years, and are progressing to international networks. The analytic methods can be divided largely into an accumulation method to analyze data in each process and add them up, and a method to use an industrial association table. The former method is the most generally used method currently in overseas countries if referred to the LCA. Because the LCA can cause the analytic result and evaluation to vary depending on the purpose, it is important to define the goal, and set the scope. The LCA must develop in the future although it has a number of problems. 10 refs., 5 figs., 2 tabs.

The photovoltaic/thermal hybrid panel (PV/T) is an energy converter that was designed for the composite use of electricity and heat. In this paper, the validity of PV/T designed for trial was evaluated based on an exergetic theory. As the result of an experiment, the electric exergetic value of PV/T and PV is each 65.8 kWh/m{sup 2} and 58.6 kWh/m{sup 2}. The former is higher than the latter by 11.2%. The total exergetic value of PV/T is also 1.2 and 8.2 times as high as those of a PV and solar collector (SC), respectively. The calculation result of the optimum temperature operation showed that the exergetic value of PV/T is 3.1 times as high as the electric exergetic value. Therefore, the operation must be performed with the electric and thermal exergetic values set in a ratio of 3.1 to 1. In this paper, the operating mode is handled in which importance was more attached to the electric exergy than the thermal exergy. The flow rate of a heating medium on PV/T is not thus the flow control that maximizes the PV/T exergy. In the future, studies including these points will be promoted. 7 refs., 7 figs., 3 tabs.

The nation's activities are being moved forward centrally with the suppression policies that follow the declaration on the voluntary regulation by the German industry to prevent global warming, which had been submitted by the German Industry Federation to the federal government in 1996. The participation to the declaration, which is optional, covers 71% of the energy consumption by manufacturing industries and 99% of the public electric power consumption, but large-scale industrial departments such as machine and electric power sectors who have not participated can also been found. The plan calls for reduction of inherent CO2 and energy per added value production amount in the entire industry by as much as 20% of the result in 1990 by 2005. According to the third party monitoring system employed by the federal government, the industry submits results of periodical analyses to the government. According to the result, the industries participated in the voluntary regulation have achieved annual exhaust suppression of 42 million tons during the period of 1990 to 1996. The public electric power industrial department whose CO2 emission accounts for a little less than 30% of the nation's total emission amount has a great effect. The industry is making efforts to improve the power generation efficiency aiming at reduction of CO2 emission of 12% of the 1990 result by 2015. (NEDO)

Targeting at proposing to ISO as an international standard, R and D has been performed on a method of the alternating current heating of the non-constant method, with regard to a method to evaluate the thermal properties test on polymeric materials in molten condition reflecting thin film polymeric materials, and the forming and processing technology. This paper summarizes the achievements in fiscal 2000. The current fiscal year has executed surveys on literatures related to thermal properties, development and commercialization of a measuring device, establishment of the measurement procedure, and putting some of the materials into database. The database was prepared mainly for heat diffusion rate and heat conductivity, wherein about 1000 items of information were collected. The temperature range of the measuring device revealed that stabilized data can be obtained from as low temperature as liquid nitrogen temperature to as high as 200 degrees C. The commercially available measuring device has no restrictions if the test sample thickness is from 1 mm to 100 mm, if the temperature range is from room temperature to 350 degrees C, if the temperature rising rate is from 0.01 to 5 K/min, and if the test sample form is film. Measurement at temperatures including those in the melting zone in the forming stage of each polymer has achieved as close result as having been called for in the initial objective. (NEDO)

The experimental research was conducted with the aim of developing test/evaluation methods of plastic optical fiber (POF) and proposing a draft on the standards to IEC, and the FY 1999 results were outlined. In the study of the band measuring method, the equipment designed was compared/verified in the pulse method with the frequency sweep method equipment for quartz base optical fiber use to confirm the accordance. Effects were further studied of experimental conditions including exciting conditions. Also about the frequency sweep method, the same verification was made to see the accordance with POF measured values in the pulse method. In the analysis by theoretical calculation, obtained were the results by which the experimental results can almost be explained. In the experiment on the optical transmission, the bit-error-rate was measured by transmitting digital signals to POF. As a result, it was confirmed that there were close relations between the band width of POF, bit-error-rate and changes in receiving sensitivity. As to the above-mentioned band experimental method, strategy for standardization was studied, and the making of a draft on the standards was started which is to be proposed at the meeting of TC86/SC86/WG1.

The field tests on photovoltaic power generation systems for public facilities have begun in fiscal 1992 by NEDO. The systems including those under construction are installed in 116 sites. Analyses were given on 75 sites which have been operated up to fiscal 1996. Analyses of the operation characteristics were performed by using performance parameters derived by developing the basic expressions into each configuration element. For the insolation on slanted surface, the range from 3.0 to 4.5 kWh/m{sup 2}/D accounts for 65% of the total insolation. For the equivalent array operation time, the range from 2.5 to 4.0 h/D accounted for 81%. For the equivalent system operation time, the range from 9.0 to 12.0 h/D accounted for 85%. The range for inverter active efficiency from 0.84 to 0.96 accounted for 79%. The inverter load rate was accounted for 88% by 0.20 to 0.35. The output coefficient was accounted for 82% by 0.7 to 1.0 in the array, and 87% by 0.6 to 0.9 in the system. The power generation cost has decreased to 200 yen per kwh in fiscal 1995 from 340 yen per kwh in fiscal 1992, largely contributed by reduced installation cost. (NEDO)

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

Toxicity of petroleum component to aquatic organisms appears as a result of its deposition onto living organisms followed by its migration into bodies of the organisms, and emergence of toxicity from the migrated component. Effect evaluation processes standing on this viewpoint may include the exposure monitoring or migration monitoring, in which the petroleum component migrated into marine organisms is analyzed and the state of the component concentrated in these organisms is measured, or effect monitoring, in which actions of the petroleum component in the organisms are investigated. The effects of petroleum on aquatic organisms would include the following occurrence: direct fatal toxicity acting on cells and membranes, quasi-fatal toxicity causing death indirectly through feeding actions and abnormal actions, direct coating of oil on surface of organisms, which prevents movability and feeding actions of the organisms and reduces hydrophilicity of plumes and hairs, pollution of living organisms due to migration of carcinogenic aromatic compounds into bodies of the living organisms, and change in species compositions and geographic distribution of living organisms due to change in physico-chemical environment. This paper explains cases of detection and identification of organic sulfur compounds, aromatic compounds, polycyclic aromatic compounds, paraffins, olefins and heavy metals in parametric compounds of petroleum. 20 refs., 4 figs., 3 tabs.

This paper describes the considerations on the influence of the global warming on the environment, and the discussions on the measures against the climatic changes. With respect to the environmental effects by the global warming, the considerations were given based on the studies on the effects of mainly the Quaternary climatic changes on the surface sea water temperatures, sea level and animal flocks. If the magnitude of the climatic changes anticipated to occur during the 21st century is lower than that have taken place in the past 10,000 years during which the agricultural production has developed to a full-scale, there would be no fear of drastically changing the ecology on earth. If the estimation of future climatic and environmental changes becomes possible, then four basic positions could be selected for establishing the contermeasure plans. That is, the first is the measures to correspond to birth-rebirth transmigration; the second is the measures to carbon dioxide disposition upon concluding that the cause for the global warming is the atmospheric increase of carbon dioxide concentration, measures for conservation and international cooperation; the third is to deal with the warming environments; and the fourth is the means to reconstruct the earth. While a number of countermeasures may be prepared, Which of them should be selected will be decided by the amount of effects. 15 refs., 6 figs., 1 tab.

The effect of residual stresses on brittle fracture was investigated on the basis of the Local Approach. Compressive residual stress was introduced by pre-loading and the subsequent fracture test conducted with a 780 MPa class steel. Preloading apparently increased the critical load and critical CTOD at the onset of brittle fracture initiation. The Weibull stress criterion was used to evaluate the brittle fracture resistance of the pre-loaded specimen. The critical Weibull stress is a material property independent of test conditions with and without pre-loading. Using the Weibull stress criterion, the critical CTOD of the pre-loaded specimen can be predicted from test results of the specimen without pre-loading. (author)

The result of a photovoltaic power generation field test in fiscal 1996 on a prefectural office building in a sunshine-rich district is reported. It is a lighting power source installed in fiscal 1994 on the third-floor rooftop of the management information building of Kanagawa Prefectural Industrial Technology Research Institute. It has a capacity of 25kW, operating on system interconnection (no back flow), and has a single 15-series/26-parallel array (mono-crystal modules) facing 38deg westward from due south and inclined at an elevation angle of 20deg. From the 240000kWh insolation that contributed to power generation, a DC power output of 28000kWh was obtained, output of 25000kWh after conversion into AC. The module efficiency was 10.8-13.8%, higher when the daily mean temperature was lower. In the case of 3kW type expected to diffuse into the residential and commercial sector and household sector, one will output 3000kWh a year, which is an appropriate capacity as a locally distributed type power generating system in view of the monthly consumption of 2000kWh by a household in general in the Tokyo Electric Power Co., Ltd. service area. No problem is found in reliability of the tested system. Although the power it generates is less than what this office consumes, it is effective in enlightening people about resources saving and peak cut in summer

With relation to the energy supply/demand in Japan toward the second half of the 21st century, an analysis was made using the MARKAL model to predict the amount of hydrogen introduction in the future. As in the last fiscal year, conditions of the study of IEA/ETSAP were continuously used. It was decided on that hydrogen was produced by hydroelectric/photovoltaic power generation overseas. Prices were made 14 yen and 27 yen/103 kcal. The limit price of introduction of import hydrogen was calculated. During the period from 2030 to 2050, if the hydrogen price is less than 7 ten/103 kcal, the result showed that hydrogen can be introduced in a lot of scenarios (case of the severe control of CO2 emissions, case of high priced fossil fuels, case of the low capacity of the development of nuclear power generation, etc.) As the form of hydrogen use, promising are the hydrogen combustion turbine power generation, mixture with town gas (hythane) and hydrogen cars. However, a precondition for the introduction is that the cost of hydrogen car should be more economical than the competitive means of transportation. As to hydrogen combustion turbines and hythane, the quantity of hydrogen introduction depends little on variations of characteristics of the equipment used. 11 refs., 55 figs., 21 tabs.

The paper evaluated performance of a flow-down collecting solar system. The solar heat pump PV system is composed of a solar system, heat pump and PV, of which the heat collecting portion is a water-use horizontal evacuated double glass tube solar collector. As a result of the performance measurement, the necessity of fundamental improvement arose. Under an idea of disproving common sense of the original forced circulation solar system, a system was designed in which heat is collected by making the heat media reversely circulate and flow down in accordance with gravity. When the flow rate was 2m{sup 3}/h, the collecting rate reached a maximum, approximately 54% (36.9% before improvement). When the flow rate was 1.3-1.5m{sup 3}/h, the system can realize the maximum merit, and the collecting efficiency became approximately 50%. Helped by reduction in consumed power, the average system performance coefficient reached more than 85% (28.9% before improvement). The obtainable energy rate rapidly increased to 2.9 times more than before improvement. Further, the consumed power of pump was decreased 65% from before improvement when the flow rate was 2.4m{sup 3}/h. 2 refs., 5 figs.

The filter performance test apparatus with three kinds of filters such as pre-filter, reverse osmosis membrane filter and ultra membrane filter was fabricated to conduct long-term cycling high-concentration tests using artificial urine as original waste water. As a result, since every membrane filter offered their nominal performance incompletely in high-concentration tests, it was necessary to add an NaCl removing apparatus to the system as primary treated water should be used for vegetation. It was also required to test the membrane performance preliminarily because the performance such as membrane life was different between various waste waters. 7 refs., 32 figs., 9 tabs.

Human auditory sensation has both extremely excellent performance and general versatility as sound analyzer. At present, it is impossible to make equipment with the same functions as human being, and describe an auditory sensation function as acoustic sensor even by any physical analysis techniques. However, extraction of auditory sensation parameters is becoming possible by using psychoacoustics and binaural signal processing. This paper mainly explains the calculation method of sound quality evaluation parameters derived from psychoacoustic results based on a sound quality evaluation system under development by the authors. This system is based on binaural measurement by dummy head, and calculates psychoacoustic parameters such as loudness, sharpness, roughness, fluctuation strength and tonality through frequency analysis of the measured stereo signals. The system also calculates 2-D parameters such as sensory pleasantness and unbiased annoyance based on the above parameters. 12 refs., 4 figs.

This paper describes the current status and how works are being carried out on safety tests and evaluation of gene recombinants in plants and microorganisms. In the field of plants, Flavr Savr tomato which has been improved in fully ripe fruit distribution and keeping quality was commercialized as the world`s first recombinant food in May 1994 by Calgene, Inc. of America. Other vegetables, such as soybean, corn, potato, and pumpkin have been completed of all items of safety evaluation, and are approaching the commercialization phase. The safety evaluation system for living organisms created by using recombinant DNA technologies has been established internationally with regard to its general framework and contents based on accumulated knowledeges and experiences as a result of utilization of over twenty years. Industrial utilization guidelines for recombinants in Japan have been established in correspondence with the OECD recommendation in 1986. Experiments to verify recombinants to be safe in environment, and cultivation of the recombinants for utilization are performed based on the experimental guidelines and utilization guidelines. 15 refs., 1 fig., 5 tabs.

Discussions were given on airbags equipped in passenger cars as to methods of evaluating their deployment injuries. Airbag deployment injuries occur in occupants being out of position. In a driver`s seat, an injury may occur when an air bag deploys under a condition that a driver with relatively short body height gets closer to a steering wheel to maintain the driving posture. In a front passenger seat, if a child is not held in a restraint equipment, the child may be blown off into the vicinity of the airbag, whose deployment can cause an injury. According to the result of a test performed on a driver being out of position, the test method using a hybrid 3 dummy specified in the present ISO procedure may not necessarily be said to produce an evaluation on the worst case. In order to solve the problem, an ATD dummy which can measure bend in each rib independently would be used, or the hybrid 3 dummy must be measured in the worst set position. 4 refs., 8 figs.

This paper reports the study results on R and D of the evaluation system for solar cells in fiscal 1994. (1) On development of the performance evaluation method for solar cells, data collection, analysis and measurement of atmospheric conditions necessary for outdoor measurement were carried out to improve the measurement accuracy of laminated solar cells. The validity of measurement methods was verified by comparing experimental results with outdoor measurement ones to improve the indoor measurement accuracy by multiple light source solar simulator. Generated energy in solar cell module level was also studied in field. (2) On development of the reliability evaluation method for solar cells, deterioration data were collected and analyzed by long-term exposure test. As a result, it was clarified that Pmax values are directly affected by seasonal change in air mass, and deterioration of solar cells is hardly found after exposure test for one year, showing a stable state. The characteristic recovery experiment of amorphous solar cell modules was carried out, and the accelerated deterioration test method of thin film cell modules was also studied. 2 figs.

This paper reports the survey results on R and D of solar cell evaluation systems in fiscal 1994. The performance/reliability evaluation subcommittee continuously analyzed technical issues and discussed solution measures from the last fiscal year. On development of performance evaluation methods, improvement of measurement accuracy for laminated solar cells is the study issue to be solved. Although laminated solar cells are measured by multiple light source solar simulator, difficult spectrum compensation causes measurement errors. Collection and analysis of data for determining atmospheric conditions, and outdoor measurement experiment under the atmospheric conditions for reference solar light were carried out. The study on incident angle characteristics of laminated solar cells clarified that the deviation from COS characteristics is 1.0% or less at an incident angle of 30{degree}. The study on generated energy in solar cell module level in field clarified that generated energy and generation efficiency are proportional to intensity of solar radiation. 1 tab.

This project is aimed at development of the testing methods which can adequately predict resistance of polymer products to weather in various areas of largely different environmental conditions. Described herein are the FY 2000 results of the outdoor exposure tests, and the tests in which the samples are exposed to light from a laboratory source and to a solar light-concentrating test unit. The FY 2000 project include the exposure of the samples directly to the outdoor conditions and glass-filtered light, which are continued from the previous year; solar light-concentrating type exposure tests conducted in Arizona, USA, started in this year; and reproduction tests for the exposure to a xenon lamp light, review of short exposure time areas and spectral degradation tests, among others. The program for evaluating the reference materials includes measurement of cumulative property changes of 4 types of plastic and 10 types of rubber materials by the exposure tests. The tests of resistance of plastics to weather have been exposing the samples, stabilized and not stabilized, for 16 months. For the reference candidate samples, the data of exposure for 1 month are collected 16 times. The tests of resistance of the rubber materials to weather reveal that each sample is deteriorated by hardening and deterioration proceeds with time. (NEDO)

This paper discusses life evaluation on phosphoric acid fuel cells of urban energy center type for regional energy supply and on-site type to be installed in buildings. Operation characteristics tests and disassembly checks allow to identify factors for voltage decrease, and estimate the life therefrom particularly if the voltage decrease is caused from catalyst activity. The time before 10% decrease value is reached is now about 40,000 hours. The creep analysis method that has been developed recently can predict deformation in full-size reformers nearly exactly, and is effective in operating the reformer and evaluating the life at the design stage. Creep buckling is the critical value, which is caused by ecliptic deformation of internal tubes in the second catalyst layer. In a heat exchanger for fuel gas preheating, carbon in the reformed gas is carbonized and deposited due to catalytic action of nickel in the brazing material that bonds plates and fins in the heat exchanger. Iron also has a possibility of performing catalytic action. In the on-site type 1,000-kW class fuel cells, no structural problems have been presented even after the operation has been stopped. In order to extend time interval between phosphoric acid supply into the cells, it is necessary to reduce difference in the remaining phosphoric acid amounts in the stack lamination direction and in the cell flat surface.

To select projects of the New Sunshine Program which is the locomotive for Japan`s research and development of energy and environmental technologies and to map out the Program`s long-term strategy, it is required to develop an effective methodology of assessing research and development themes. It is also necessary to establish the pre-assessment system which makes the assessment process more logical and which will enable the priority setting among different themes on the basis of objective and quantitative analysis. Additionally, transparency should be ensured for such a pre-assessment process through disclosure to the public and other means. The present survey aims to concretize the pre-assessment system by studying the system and techniques of an assessment system which is applicable to the research and development themes of the New Sunshine Program and is objective, quantitative and logical and which can ensure transparency and by receiving suggestions on the pre-assessment of Japan`s research and development of energies and environmental technologies through research on overseas trends of government-led research and development. 3 refs., 7 figs., 26 tabs.

Study was conducted with the aim of developing the standard tensile test method which enables the measurement/evaluation of mechanical properties of various kinds of thin film materials with thickness of 10{mu}m or below and width of 100{mu}m or below and of making it a draft for the international standards. The FY 1999 results were summarized. As to the Round Robin Test, Si test pieces were so fabricated by bulk micro-machining that comparisons in testing method can easily be made. Concerning the test machine, the measurement of deformation and strain of test pieces at the time of tensile test was made possible with the introduction of an optical microscope with interferometer and CCD camera for image processing. The measurement was also made possible of Young' modulus of polycrystal Si films of test pieces different in length. Relating to the optimization of standard test pieces, basic tests were carried out on the analysis of gradients of sputter thin films/the trend of grain formation state, measurement of residual stress of Ni plated films, etc. In the survey of the adaptability to standardization, it was found out that industrial circles in Europe and the U.S. are not interested in the standardization which produces no direct profits.

R and D has been performed on methods to repair composite structures used in aerospace application, and on stress evaluation on repaired portions, targeting at establishment of international standardization. This paper summarizes the achievements in fiscal 2000. The current fiscal year has executed surveys on repair methods, selection of the repair methods, evaluation on the repairing processes, and compression strength evaluation on test samples given repairs. The method for repairing the sandwich-structure composite members was selected as a result surveys and discussions on published literatures. For the evaluation test on the repairing processes, specific repairing processes were established with reference to the result of surveys on the repair methods, which were applied to test samples having been given damages. In addition, discussions were given also on non-destructive inspection methods for sandwich panels. Regarding the strength test for repaired portions, a compression strength test was performed on test samples repaired by using adhesive after having been given damages, wherein data related to compression strength were obtained. Furthermore, a system was developed to analyze the scarf-like adhesive-repaired potions by using the two-dimensional finite element method model. (NEDO)

In ISO1328 that covers specifications on precision of toothed gears, gears are graded according to the magnitude of error, but there is no system established for guaranteeing measured error values for accuracy. Activities are conducted for realizing such a guarantee, for establishing methods for testing and evaluating gear precision measuring devices, and for working out international standards for them. It is decided that the current status be investigated and then a concrete method be proposed as an international standard centering about gear precision measuring digital devices which will stay important in the future. A digital measuring device enhanced in precision is constructed by way of trial, and then it is proved that the newly fabricated device works effectively in the calibration of gear precision measuring devices in general use. Thanks to this process, basic data are collected about the measurement of gear precision using a gear precision measuring digital device, and this enables the preparation of a draft of criteria for international standardization.

Japanese paint users demand products of higher-quality than users in the U.S. and Europe, and therefore, paint makeres in Japan are making strenuous efforts to improve the product quality in terms of homogeneity, appearence and durability of the surface of paint films. However, the evaluation of paint surfaces is conducted by the qualitative sensory evaluation, resulting in obtaining no appropriate evaluation. Accordingly, the following were developed as new evaluation methods which give rational and economical indicators, contribute to shortening of the period for development of new products, and aim at the international standardization: 1) quantitative evaluation of the paint drying process; 2) image analysis of the degraded part of paint films; 3) surface analysis of paint films. In 1), a kinetic friction measuring quantitative evaluation of the surface of paint films was developed. In 2), the development of an exclusive program by the image analysis made the quantitative evaluation with high accuracy/reliability possible. In 3), an evaluation method was developed in which differences among the specimens can be detected by the chemiluminescent measurement in an extremely early stage of exposure when the gloss change just begins. As to the chalking, a new evaluation was developed in which the degree of chalking can quantitatively be evaluated by attaching a special adhesion tape to the degraded part of paint films and by the optical measurement of the degree of transparency. 101 refs., 341 figs., 118 tabs.

Computerized Safety, Maintenance and Operation Systems of Shinkansen (COSMOS) has been developed to properly deal with the diversification and modernization of Shinkansen business and the improvement of its system. To avoid the concentration of duties and loads on any part of the system, the system functions are distributed into eight subsystems, which respectively cover transportation planning, operation management, maintenance work management, power system control, rolling stock management, centralized information management, facilities management, and yard operation management. The COSMOS is a huge system distributed across a large area whose 500 computers and terminals located in the eight subsystems and offices related with Shinkansen are linked by a network. A concept of autonomy and distribution is introduced into the system so that the impact on the others will be kept to the minimum in case some subsystems come to a stop. The new system is excellent in maintainability, flexibility, and extendability, and its operation room is quite compact. The COSMOS has been working smoothly since the beginning of its service, contributing to the modernization of Shinkansen business, such as rapid restoration in case of timetable disturbance, reduction in station workload, improved passenger guidance service, and centralization of section control business. 5 refs., 2 figs.

Concerning a high level treating method of regeneration of sewage water, there are methods of coagulation/precipitation, sand filtering and ozone treatment in addition to the conventional active sludge method. However, none of these methods are perfect from the viewpoint of virus. A film treating method to remove micro-organisms in water is twofold, i.e., microfiltration and reverse osmosis. For such filter treatments, polio virus is most suited as an experimental index for conducting an assessment of the treating ability of viruses. The reasons are as follows: 1. It is the smallest virus among the viruses which are mixed in the water systems. 2. Polio virus is always detected in the study of actual conditions of the viruses contained in the sewage waters. 3. It involves less danger in handling because there are vaccines which are made less poisonous. 4. Separation and quantification of viruses is easily conducted by means of cultured cells. 8 refs., 1 fig., 7 tabs.

A demonstrative test was conducted to verify economical efficiency of practical scale hydroponic horticulture under structure making use of a part of the Osaki thermal power plant to be constructed. In the test, the hydroponic culture of leek and tomatoes was carried out for six years starting 1989 to study its economical efficiency. Using the M-type hydroponic culture facilities, the structures are 1200m wide, 29m long, and 21 tons in the culture liquid level in case of leek, and 350m wide, 29m long, and 10 tons in the culture liquid level in case of tomatoes. The evaluation was made estimating the crop amount of leek as about 35 tons and that of tomatoes as about 60 tons and regarding that the sales amount is equal to the crop amount. The sales amount of leek is 28 million yen, and when seeking income/expenditure from expenses, deficit of 1 million yen per 30 a cannot be avoided excluding the equipment depreciation cost. As to tomatoes, the shipment cost is approximately 14 million yen without the equipment depreciation cost, but the sales amount is approximately 13-19 million yen largely affected by the unit price. A study on the sale method is needed. 7 figs., 11 tabs.

In order to reduce the economic cost of the generating set etc. the damages to the materials and structures of the structure to last the original design life were observed and it was considered that if damages were fewer the life would be longer. One of the important items in assessing, amending and renewing the rationality of the established structure is the assessment of the defects and flaws existing in the welded joints. In Japan, WES 2805 which is named as the Method for Assessing the Defects for the Brittle Fracture Occurring Properties of Welded Joint was formulated in 1980 as the standard of the Japan Welding Society. Although it has been applied as the criterion in wide range, the part on brittle fracture is now under revision to reflect the research results on fracture mechanics thereafter and to perfect the fracture relationship because many years have passed since its first formulation. In this paper, the contents in the final stage of the revision of WES 2805 standard, including concrete examples, were introduced. 2 refs., 6 figs., 2 tabs.

In this study, seismic monitoring of injected gas in a carbonate reservoir was investigated using multidisciplinary approach which consisted of geological/reservoir modeling, reservoir flow simulation, rock physics and seismic modeling. A case study was conducted over Lower Cretaceous carbonate reservoir offshore Abu Dhabi. The gas saturation and reservoir pressure data were obtained from the reservoir flow simulation. The velocity data of dry rock samples under the various conditions were also obtained from rock physics study. These outputs were converted to the velocity model using Gassmann's equation. The calculated velocity from Gassmann's equation is well correlated with velocity from laboratory measurements. Therefore we con confirm that the Gassmann's equation is applicable to estimate the velocity of the gas saturated reservoir rock. Based on the velocity model, synthetic seismic sections before and after gas injection were constructed in order to verify the influence of gas flood. As the results, amplitude difference between the two synthetic seismograms was observed at top and bottom reflectors of the reservoir zone. This amplitude variation is caused by both gas saturation change and pressure change. Although further investigation is needed to detect the cause of the variation, this study indicates the possibility of seismic reservoir monitoring. (author)

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.

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

The on-and-off timing of vehicle headlamp control systems varies with weather conditions. Cloudy weather has a wider light energy distribution from visible to infrared radiation than clear weather. Silicon photodiodes, which can detect visible to infrared radiation, have larger output currents on cloudy evenings than on clear evenings under the same brightness conditions. The systems should be designed with such factors in mind as spectral characteristics of windshield, filters, sensor, and eyesight. 4 refs., 9 figs.

The present report introduces the technological trend of rainwater drainage information system mainly with radar rain gauges. The information network must be strengthened as measures against the urban flood from the rainwater drainage. A radar rain gauge-based combination is needed of synthetic and organic processing technologies covering the traveling prediction of rainfall, data communication and rainwater drainage/flooding prediction. The correction method and data communication/display technology are explained for the measurement with radar rain gauges. In both correlation function method and rainfall area pursuit method, the traveling of rainfall is predicted by utilizing the radar information for the sewerage system. For the drainage analysis, it is necessary to quantitatively estimate the rainwater drained into both main and branch sewerage lines. It is made by preparing a rainwater drainage model. The quantitative estimation of rainwater drained into the branch sewerage lines calls for a revised Road Research Laboratory guidance by the Ministry of Construction. Supplemented with knowledge by veteran operators, the displayed image of pump operation support system is simulated for its verification. 2 refs., 3 figs.

Targeting at realization of international standardization of a textile material (geotextile) used for interlocking concrete block pavement, R and D has been performed on a performance evaluation method consistent with field works. This paper summarizes the achievements in fiscal 2000. A literature survey has revealed that manuals prepared by the U.S. AASHTO, and ISO related standards show the test method for single geotextile, and guidelines on durability, but the method for evaluating the durability assuming the actual using conditions has not been standardized. The result of a field test reveals definite effects of existence of geotextile on the usability of block pavement in the water permeable bitumen stabilized roadbed, wherein the effectiveness of the geotextile was verified. In the research of an indoor evaluation test method, it was identified that the test method using a roller compactor and a wheel tracking testing machine can reproduce the behavior of block pavement at site, and it is a method that can identify the durability of the geotextile to some extent.

As to the evaluation method of the strength of aerospace use composite materials and the repair materials/repair parts, the R and D were conducted for international standardization. The FY 1999 results were summed up. Concerning the damage resistance of base structure, tests to give damages to three kinds of sandwich panels and tests on the strength of damaged parts were conducted, and it was confirmed that the foamed core was more easily damaged and less in strength lowering than the honeycomb core. Relating to damages of composite material parts which are caused by aircraft operation, surveys were carried out at Swissair, Japan Air Lines and Lufthansa German Airlines. In the investigational study of the repair method of composite material structures, it was found out that there were typical forms of repair: only one face plate, one face plate and core, and both face plates and core, and according to these, the analysis of strength should also be adopted. The survey of the repair method was also made at each airframe maker. In the study of the analysis method of strength at repair parts, it was confirmed that the finite element method was high in accuracy and can be adopted also to complicated shapes, and that it was a method suitable for the actual analysis of repair strength.

The paper studied the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. Chemical composition and coating thickness (g/m{sup 2}) of 14 kinds of specimens including alloy coatings and organic coating with zinc and aluminum as base were analyzed by the above-mentioned methods to examine the relation between the both. As the chemical analysis method, used was inductively coupled plasma atomic emission spectrometry. To study the relation between the methods, it was found to be necessary to recognize morphology at the boundary between the coating and base steel using, for example, scanning electron microscope (SEM) and electro-probe micro-analysis (EPMA). To measure traceability of the analysis method, with the chemical analysis method as a judgement method, it is necessary to make reference materials by coating materials, to use the calibration graph confirmed by the materials and to adopt the glow discharge optical emission spectrometry. On the basis of such way of thinking, drafts were worked out for the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. 7 refs., 117 figs., 33 tabs.

Described herein are the results of the FY1994 research program for analysis and evaluation for thin substrate polycrystalline solar cells. In order to analyze the structures of the grain boundaries in and interfaces with the cell substrate, and their effects on electrical activity, the photoluminescence (PL) measurement which enables spectroscopic analysis is applied to electromagnetically cast Si crystals. There are good correlations among PL luminous intensity, MBIC output and dislocation density for the grain boundary which contains many strains and serves as the dislocation source, because carriers in such a grain boundary easily disappear to reduce its luminous intensity at the band ends. Concrete scenarios for realizing thin-film silicon solar cells of high efficiency are presented, based on the analysis of the light-contained thin-film silicon solar cells of high output current, made in the previous year on a trial basis. An alumina substrate of high reflectivity is produced by the experiments of combining various devices. It is expected to realize high output current for the thin-film solar cells. 3 figs.

This paper reports the achievements on research of pyroelectric power generation systems in fiscal 1998. In the research, a small continuous pyroelectric conversion equipment was fabricated and experimented. The experiment using an aluminum foil electrode revealed that the foil melts during discharge opening holes, thus making it impossible to increase net conversion efficiency. The net conversion efficiency was derived in an experiment using foil evaporated with indium instead of the aluminum foil. Indium has inferior electric conductivity to aluminum, but is melting point is as low as 145.6 degrees C. Therefore, if a pyroelectric film had electric fatigue due to use over an extended period of time, indium may be melted to make recovering and reusing pyroelectric copolymer possible. Thus, the indium electrode was found suitable for pyroelectric conversion. Analysis of the experimental data indicated that the final possible net output can be 7.6 W/m{sup 2} if each operation variable considered possible in the future is superimposed on the pyroelectric film. This survey revealed that low-temperature waste heat can be converted to high voltage continually by using the pyroelectric conversion equipment at CANMET Energy Technology Centre. (NEDO)

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

The author expresses his opinion toward the impact to be brought about by changes in evaluation standards mainly involving the power system. The 20th century has been an age of mass production of various articles and mass consumption of various resources. It has become evident of late that flexibility, which will realize environmental impact reduction and satisfy varying needs, should be added to the evaluation standards. The new evaluation standards urge that the large-scale centralized management type system be converted into an autonomous distributed type system, and mass production into small-scale production of multiple articles. The development from centralization to decentralization, and the trend toward deregulation and the corporation's plan of dividing itself into plural in-house companies, may be evaluated against the same context. In the field of power systems, it is deemed that the diffusion of power retailing business and distributed power sources will be accelerated. When it comes to a power system constitution and operation capable of dealing with the new development, an autonomous distributed type system constitution and operation as a local energy system is supposed to be more appropriate than the conventional centralized management type.

The multi-offset hydrophone VSP experiments were carried out using a 750m deep borehole as the oscillation receiver, which penetrates the Nojima fault, to detect water-permeable cracks and evaluate their characteristics. Soil around the borehole is of granodiorite, and fault clay is found at a depth in a range from 623 to 624m. A total of 4 dynamite tunnels were provided around the borehole as the focus. The VSP results show that the tube waves are generated at 22 depths, including the depth at which fault clay is found. However, these waves are generated at only 6 depths in an approximately 150m long fracture zone, suggesting that the cracks in the zone are not necessarily permeable. It is also found that crack angle determined by the analysis of tube waves almost coincides with that of fault clay determined by the core, BHTV and FMI, and that permeability is of the order of 100md at a depth of fault clay or shallower. 3 refs., 2 figs., 2 tabs.

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

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

An attempt was made to visualize distribution of cracks in a rock slope by applying geophysical survey onto a rock slope. Geophysical logging and seismic survey using the reflection method were used as the methods for the geophysical survey. The rock slope subjected to the survey is located in a gorge along the Yoshino river in Yamashiro Town, Tokushima Prefecture. The slope has a width of 25 m and a height of 30 m. Its overhang in a nose form may has a possibility of causing collapse due to sliding. Cracks developed by horizontal schistosity were detected by performing geophysical logging on VSP, calipers, natural gamma-ray spectra, temperature and borehole in a borehole drilled vertically from the top of the slope. The seismic survey using the reflection method detected the cracks by emphasizing joints in the perpendicular direction. A possibility was shown to visualize the crack distribution with high resolution by using the above geophysical survey on the rock slope. In order to detect the crack distribution with still higher resolution, development into a three-dimensional exploration in the future is desired, not to speak of improvement in signal receivers, and discussions on geometry. 1 ref., 6 figs.

In order to evaluate disaster potential and disaster prevention potential of landslides, which are complicatedly composed of natural factors and social ones, an evaluating method of the potentials is proposed by applying the multiple logistic model. Furthermore, a method making the potential map using this evaluation is shown. The multiple logistic model is based on the conception of multiple risks, and so the disaster potential is expressed with probability. The disaster prevention potential is evaluated by using the disaster potential. Taking a typical landslide district as an instance, some potential maps colored by each potential are shown. By these maps, effects of the preventive measures against disasters and changes in the disaster prevention potential according to the industrial structure as well as the population are evaluated. Furthermore, combination of the other disaster potentials obtained by changing the surveying interval or factors makes it possible to draw various disaster maps and disaster prevention ones for different purposes. 15 refs., 17 figs., 3 tabs.

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

As to fiber materials (geotextile) used for block paving, survey/experimental study were carried out with the aim of establishing an evaluation method of the performance which has accordance with the site and of proposing it to international standards. The FY 1999 results were outlined. From the results of the literature survey abroad and in Japan, it was found out that the evaluation method of geotextile as simple substrate had already been standardized, but the evaluation method for durability/separation performance/drainage performance as the block paving system was not standardized. The use of geotextile in block paving is mostly for prevention of outflow of cushion sand, and geotextile is paved in the boundary between sand cushion bed and roadbed. From the survey of durability/properties in IL block paving where geotextile was laid, the useful basic data were obtained. About geotextile, there are correlations between the elongation rate and the tensile strength. It was confirmed that the geotextile laid on granular materials is higher in elongation rate, and it is less in damage than that on the permeable bitumen processed roadbed. (NEDO)

No method is available for quantitatively evaluating the performance and safety of antibacterial fabrics, and the lack impedes smooth implementation of international trade. As a measure to remedy the fault, a test method is developed for quantitative evaluation, and presented for acceptance as an international standard. In the proposed antibacterial test, 2ml of liquid with its bacterial population increased to 10{sup 4}/ml in a preculture is filtrated under reduced pressure for the trapping of bacteria in the filter paper, the paper is scrubbed by a test cloth for transfer, the cloth is left in a constant-temperature constant-humidity chamber, and the bacteria are washed out and then counted by chemiluminescence. The change in the number of bacteria thus determined is used to quantify the antibacterial feature. Safety is examined by a skin irritancy test method using a cultured skin model. A specimen is attached to a cultured skin model, left in a constant-temperature constant-humidity chamber for a specified time period, and then peeled from the model. The cultured skin model is dyed by an MTT enzyme. Unaffected live cells are dyed violaceous by the MTT enzyme. Dyed cells are solvent-extracted, and the number of dyed cells is determined by colorimetry. The number of cells remaining alive is compared with a reference specimen for the determination of the degree of safety. (NEDO)

This project studies the testing/evaluation methods for spreading fuel cells for automobiles. Described herein are the FY 2000 results. The problems involved in evaluation of the single cell units are classified into those involved in the cell construction and methods of evaluating the operation performances of the single cell units. These problems are analyzed mainly by literature survey. The mode simulation tests will be greatly simplified, if the system can be tested on the bench without being actually boarded on the vehicle. Therefore, this project is aimed at development of a comprehensive mode simulator which can be automatically operated corresponding to the running modes of various countries, to test the performance of FCEV and to examine the effects of each component independently on the vehicle performance. The factors required to reproduce the actual driving states of an FCEV on the bench are analyzed, and the conceptual designs are drawn for the controlling algorithms. It is necessary to standardize the stack and reformer testing methods, in order to evaluate the fuel cell system components. For these objects, the prototype units are constructed to evaluate 10kW direct hydrogen type stacks and 5kW methanol reformers. The units are also constructed to evaluate the high-pressure (1MPa) reformer reactors and hydrogen separation membrane systems. (NEDO)

The paper described the fiscal 1997 result of the study of scenarios for introducing hydrogen to the urban area. In the case of studying it in London, it was found that hythane (mixture of hydrogen into town gas) was effective, but in the case of doing in Tokyo, it was found that the scenario was undesirable because of the increasing infracost. Accordingly, another scenario was studied. It was assessed from the aspects of environmental advantages, infracosts, and potential advantageous values in urban areas associated with hydrogen utilization (hydrogen premium). It is most effective to use hydrogen as a fuel of transportation means from the aspect of environmental merits as the decrease in external cost. In Tokyo, the dependence upon electric power is large, and therefore it is attractive to introduce highly efficient fuel cells which enable the dispersed cogeneration using hydrogen. The value of hydrogen is determined by the avoidance of environmentally influential substances and the surplus generated output by fuel cells (substitution for the existing natural gas). When the high external cost can be assumed, the value of hydrogen becomes large. The paper also considered the arrangement of infrastructures in Tokyo. 187 refs., 14 figs., 18 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)

Electron paramagnetic resonance (EPR) of coals was considered by using iodine doping technique. Sub-bituminous coal (WA) and bituminous coal (UF) were used to observe EPR spectra using microwaves. With the UF coal, strength of the narrow component of the spectra was found constant regardless of amount of the doped iodine, wherein radicals without interaction with iodine were detected. Strength of the broad component increased with the iodine doping amount, where in deviation of {pi} electrons was detected, which have been generated as a result of interaction between aromatic rings and iodine in the coals. Spin concentration of the WA coal with low coalification degree is constant regardless of the iodine doping amount, and the interaction of the iodine with the aromatic rings was found small. The higher the coalification degree, the more the aromatic ring structure grows, and electron donor capability for the iodine increases. In a system with the entire spin being uniform, the spectrum height shows a saturation phenomenon against increase in microwave output. A non-uniform system, in which the oriented spin forms small groups and is in local thermal equilibrium, does not show saturation, but increases monotonously. 2 refs., 5 figs.

In experiment, film flotation was applied to Illinois coal modified by aqueous methanol solution and kerosene adsorption, and the weight percent of residual particles on a gas-liquid interface and kerosene in aqueous methanol solution were analyzed to verify the applicability of a film flotation method. Film flotation was applied to Datong and Illinois coals modified by kerosene adsorption, and the weight percent of residual particles on a gas-liquid interface was plotted to surface tension of liquid. As a result, the weight percent of hydrophobic particles within 50mN/m in surface tension slightly increased in Datong coal and remarkably increased in Illinois coal with kerosene addition. It was thus suggested that in addition to surface tension, the distributions of hydrophilic and hydrophobic strengths on the surface of each coal particle should be considered to understand attachment of coal particles and bubbles. 6 refs., 4 figs.

The authors proposed an aeration filling method as a new filling method in order to obtain uniform and high speed filling by carrying out basic experiments on powder material filling using a visual apparatus. In this study, the aeration powder filling was applied to the product compacting on the actual compacting press, and its evaluation was carried out. As a result, the following effects were confirmed. The weight scattering was reduced to about 70% in the high speed filling and about 50% in the low speed filling. The maximum density was reduced to about 30% in the high speed filling and about 25% in the low speed filling. The maximum thickness difference was reduced to 65% in the high speed filling and about 20% in the low speed filling. The aeration powder effect was stronger in the high speed filling than that in the low speed filling. The weight and size accuracy of the components were increased by the aeration powder filling. The pause and the shaking operation were discarded in the front part of the powder box, thus the filling time could be remarkable shortened. 3 refs., 6 figs.

This report describes the historical procedure of a bacterial test for a certain respective bacteria, and also describes the removal of micro-organisms by a water treatment and treatment with disinfectants. The disinfection is made mainly on basis of foreign literature. This is because there exist few literature published in Japan. In a good sense, this is because of the Japanese habit of drinking raw water which has contributed to high level of facilities and the maintenance. If seen from a different viewpoint, the prsent concern is concentrated to a contamination of the underground water by organic solvent and the counter measure against such minute quantity of organic chemicals as trihalomethane and the agricultural chemicals in the golf courses. From the consumers {prime} standpoint, these are of the level of problems that only one affected person increases per year for 100,000 inhabitants even if they continue to drink such drinking waters continuously through their life years. The reality is that it is remote from the realities in life. 37 refs., 9 tabs.

To evaluate the risk during longevity of reinforced concrete structure subjected to earthquake motions, called lifetime risk, damage and safety were estimated by means of the earthquake risk analysis and earthquake response analysis. For the earthquake risk analysis, historical earthquake data with relatively low accuracy were efficiently taken into account, to determine the annual mean generation probability against the earthquake motion strength in ten main cities. A new damage index with load hysteresis was defined as an anti-earthquake evaluation index where accumulative damage is taken into consideration. Assuming that the damage transits from `certain state` to `certain state` every time the earthquake motion generates at the noticeable place, damage transition matrix expressing transition probability was calculated by using the results of earthquake risk analysis and the accumulative damage index. The lifetime risk was calculated from the damage transition matrix and the earthquake motion generation probability, to evaluate the safety. 21 refs., 10 figs., 8 tabs.

The members of MHD project examination subcommittee made an investigative tour of the U.S. on the state of development of MHD generation. This report of the 2nd part explains opinions and the present status of the R and D on MHD generation by each of the 19 institutions visited. The U.S. research on MHD generation is under the leadership of DOE, whereby the budget for the development is so large as nearly one hundred million dollars have been provided for several years. The purpose is the effective use of domestic coal. General Electric is of the opinion that a combined gas turbine system will be put to practical use earlier because MHD takes time for practicability despite its highest efficiency in coal-utilized power generation. Yet, GE thinks MHD will be more attractive in the future. Reynolds Metal is considering application of MHD generation to the electro-chemical industry at present. According to Reynolds, combined supply of electric output and heat of MHD can reduce the use of calorie per ton of aluminum from 240 MBTU to 100. Montana Power is promoting practicability through a combined plan with DOE-built MHD generation. (NEDO)

A high speed towed type physical and chemical observation marine robot named as `Flying Fish` has been developed since 1992, which can measure chemical substances in the sea as well as physical data, such as flow velocity of the ocean and water temperature. This paper describes its formation, designing, control system, and results of ocean tests. For the space continuous observation of physical, chemical, and biological quantities, it is essential to control the depth, pitch, and roll. The wing control method was employed for this robot. As a result of the ocean tests, the following conclusions were obtained. The accuracy under the steady state was {plus_minus}0.05 m in the depth, {plus_minus}1 degree in the pitch, and {plus_minus}0.5 degree in the roll. This was stable enough to operate chemical analysis, such as dissolved oxygen analysis. Even under the unsteady state during the change of depth, the pitch and roll were controlled in {plus_minus}3 degree and {plus_minus}0.5 degree, respectively. Results of the field tests and the numerical simulations for the performance of this robot were agreed well mutually in the practically sufficient accuracy. 10 refs., 15 figs., 2 tabs.

With an objective for spatial continuous measurement of physical, chemical and biological amounts in ocean, development has been made on a wing controlled towed vehicle, `Flying Fish` which is capable of controlling depth, pitch and roll. Numerical simulations and two-year sea experiments have been carried out for the development. Flying Fish consists of a sub-system comprising a towing vehicle, towing cables, and on-board controllers. In a steady state, Flying Fish can be controlled at accuracy for depth of {plus_minus} 0.05m, pitch of {plus_minus} one degree, and roll of {plus_minus} 0.5 degree. This accuracy is sufficient for operating a chemical analyzer, the dissolved carbonic acid analyzer. Even in a non-steady state such as in changing the depth, the pitch can be controlled at {plus_minus} 3 degrees and the roll at {plus_minus} 0.5 degree. This extent of attitude change is within a range rendering no problems in maintaining accuracy of the measurement devices. The result of sea experiments for movements of Flying Fish agreed with that of the numerical simulation at practically usable accuracy. Flying Fish is verified as an effective system in investigating spatial variations in ocean data. 10 refs., 15 figs., 1 tab.

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

The R and D were conducted with the aim of standardizing a testing method for appropriately predicting weatherability of polymer products also in areas where environmental conditions are largely different and of proposing it to ISO. The FY 1999 results were outlined. In this fiscal year, methods to test weatherability of polymer products abroad and in Japan were surveyed mostly on JIS and ASTM, and the state of tackle with the making of standards in each country was also surveyed. In the tests on plastics and rubber, the following were conducted: selection/fabrication of test pieces, 3-year outdoor exposure tests in three places in Japan where environmental conditions are different, in the U.S. and in Indonesia, artificial light source exposure tests for about 200-1000 hours using xenon lamp, and the subsequent measurement of physical properties. As a result, about plastics, changes were confirmed in case of having no prescription of weatherable stabilizer, and changes in property values were in the range of prediction in case of having prescription. About rubber, changes in physical property after the direct exposure test were large in the U.S. and Indonesia. The effect of antioxidant was recognized. (NEDO)

No method is available for quantitatively evaluating the performance and safety of antibacterial fabrics, and the lack impedes smooth implementation of international trade. As a measure to remedy the fault, a test method is developed for quantitative evaluation, and presented for acceptance as an international standard. In the proposed antibacterial test, 2ml of liquid with its bacterial population increased to 10{sup 4}/ml in a preculture is filtrated under reduced pressure for the trapping of bacteria in the filter paper, the paper is scrubbed by a test cloth for transfer, the cloth is left in a constant-temperature constant-humidity chamber, and the bacteria are washed out and then counted by chemiluminescence. The change in the number of bacteria thus determined is used to quantify the antibacterial feature. Safety is examined by a skin irritancy test method using a cultured skin model. A specimen is attached to a cultured skin model, left in a constant-temperature constant-humidity chamber for a specified time period, and then peeled from the model. The cultured skin model is dyed by an MTT enzyme. Unaffected live cells are dyed violaceous by the MTT enzyme. Dyed cells are solvent-extracted, and the number of dyed cells is determined by colorimetry. The number of cells remaining alive is compared with a reference specimen for the determination of the degree of safety. (NEDO)

The effects of tsunami and seaquake on large floating structures are theoretically studied, where these effects are followed in terms of local strength using the equation proposed by Sells to predict surface shapes changed by seaquake-caused uplift of the seabottom. The equation is combined with the one for tsunami propagation, to better predict the tsunami motion. The simulation results indicate the necessity of considering the effects of tsunami for the design of a large floating structure. The authors discuss that the effect of tsunami is minimized when a floating structure is set at a depth of at least 40 to 50m, chain length should be determined by equalizing the breaking weight with the load at which the structure starts to move, and a structure should be set at a position where it is not attacked by transverse waves. They also discuss that seaquake intensity should be predicted by the equation of motion of compressible fluid, and, noting local strength of a floating structure, it will not be damaged when it is at least 16mm thick under the conditions of 2m as seabottom uplift and 0.5m as draft depth. 15 refs., 9 figs., 2 tabs.

Described herein are characteristics of photovoltaic (PV)/thermal hybrid collectors (PV/Ts), in which a PV module is combined with a plate-shape solar heat collector to simultaneously produce electric power and heat. Their efficiency is assessed by exergy. The test results indicate that the PV/T system gives a 1.07 times higher exergy than the PV system, 86.3 versus 80.7kWh. In terms of energy, the optimum values (OVs) are 5, 44 and 37% lower than the measuring values (MVs) for electrical energy, thermal energy and total exergy. In terms of exergy, on the other hand, OV is 5% lower than MV for electrical energy, but 893 times higher for thermal energy and 1.26 times higher for total exergy. As a result, the exergy level is 26% higher than that of a system which generates power as the main product and heat as the auxiliary product. 3 refs., 6 figs., 5 tabs.

Hydrophone VSP (vertical seismic profiling) experiment is under way as a technique for detecting subsurface water-permeable cracks by use of boreholes and for evaluating their characteristics (permeability index, crack direction, dip angle). In this report, tube waves observed by hydrophone VSP are subjected to analysis for the determination of water-permeable crack characteristics, the impact caused by errors in the value inputted for analysis is estimated, and a model calculation is performed in case there is no agreement between data from the borehole and data from VSP, all for examining the VSP records for accuracy. When an error rate of 15% is given to the tube wave/P-wave amplitude ratio, a change of 40% or lower results in the permeability index, and a change of 10deg or less in the dip angle, which means that an error in the amplitude ratio does not affect the analysis very much. Changes in the amplitude ratio resulting from changes in crack direction and dip angle differ, dependent on the offset rate. When angular differences among plural crack directions are within 90deg and dip angles within 60deg, the result of analysis represents the average characteristics of the plural cracks. 7 refs., 5 figs., 2 tabs.

In this method, functional size expressing the size of functional kinds provided by the system, value-added size expressing the size with corrected functional size in response to the quality level of each function, and production size expressing the size of products and processes under the given conditions were employed as indexes for evaluating the size of system. In addition, a method using the quality property tree has been developed. In this method, to evaluate the quality level which is essential for calculating the value-added size, users and providers evaluate the system quality from their own viewpoints. By this system, validity of user`s demand and validity/efficiency of realizing process can be evaluated for client/server type systems from the systematic viewpoint in a whole life cycle of systems from development planning to abandonment of systems. 24 refs., 5 figs., 3 tabs.

The authors discuss that the effect of tsunami is minimized when a floating structure is set at a depth of at least 40 to 50m, chain length should be determined by equalizing the breaking weight with the load at which the structure starts to move, and a structure should be set at a position where it is not attacked by transverse waves. They also discuss that seaquake intensity should be predicted by the equation of motion of compressible fluid, and, noting local strength of a floating structure, it will not be damaged when it is at least 16mm thick under the conditions of 2m as seabottom uplift and 0.5m as draft depth. 15 refs., 9 figs., 2 tabs.

Aiming at production of ethanol, fat and oil and so on, ten kinds of miscellaneous cereal crops such as pearl-millet, soybean and so on were grown, and comparative investigation of the production rate which was considered utilization of whole plants were carried out. The suitability of vegetable wastes as methane fermentation materials for the methane gas production was investigated by the constituent analyses and methane fermentation experiments. Nine kinds of the grasses and vegetable wastes such as tomatoe buds, broccoli leaves were used for the investigation. As the results, the estimated yield of ethanol per 10 are from pearl-millet was 690 liter, the estimated yield of fat and oil per 10 are was 70 liter from soybean, The results of the analyses of nine kinds of the farm residues were as follows: (1) carbon content of about 40 %, (2) C/N ratio of 13 av., (3) C/P ratio of 91 av., and (4) the content of C,N and P was roughly appropriate. 680 to 760 milliliter of methane gas was produced from one gram of the dry matter of tomatoe bods, and in case of broccoli leaves, 424 milliliter of methane gas was produced, it was found that these values were not inferior to animal dung.

Researches were conducted with a view to organizing projects for developing intelligent fibers, equipped with environmental friendliness and amenity without being deprived of their original properties as structural and clothing materials, the ultimate goal of the effort being the creation of harbingers of next-generation fibers which would contribute to the advance of industries related to environments, medicine and welfare, and information. What were learned from fiscal 1998 researches are mentioned below. The strength that the general-purpose fibers currently in use exhibit is so small as to be but several percent of what is theoretically predicted for them. Demand will increase a great deal if the actual strength is doubled, for which new technologies have to be developed including those involving super-fiber texture control. For providing the fiber with such functions as environment-friendliness, amenity, etc., it is necessary to develop phasal structure control technologies with regard to fiber morphology, surface texture, etc. For success in practical application in the future of such super-fiber materials, each specimen needs to be manufactured in the order of kilogram by way of trial. Moreover, fiber evaluation techniques have to be developed in the three domains of software, hardware, and interface. (NEDO)

Remaining life assessment technologies for polymeric materials for geothermal power generation and methods for improving their heat resistance are reviewed, and concepts of scale-free technologies for FRP (fiber-reinforced plastic)-sandwiched pipelines for hot water transportation are described. Materials based on PTFE (polytetrafluoroethylene) and NBR (acrylonitrile-butadiene rubber) are chosen for use as DHM (down-hole motor) sealing material and for application to the stator. With PTFE as the matrix, four candidates are prepared, which are additive-free PTFE, and GF/PTFE, GF/CF/PTFE, CF/PTFE, each containing 20w% GF (glass fiber) and/or 20w% CF (carbon fiber). With NBR serving as the matrix, two candidates are prepared, which are NBR-A containing 20w% aramid fiber and NBR-W which is a vulcanized NBR-A. External force, heat, light, and mud are named as the degradation factors, and each factor and some combinations of external force, heat, and light are repeatedly imposed on the materials. During the effort to develop an apparatus for simulating geothermal circumstances in which the factors will affect the materials in complicated ways, a life assessment technique is developed for such polymeric materials. A technology is developed for providing polymeric rubber elastomer with a heat resistant feature. A study is made to replace transportation pipelines for injection wells with FRP sandwiched pipelines. (NEDO)

This paper describes a method for evaluating grouting that is a means for improving the ground for excavation for building underground structures in urban areas. This is an effort for improving reliability, and evaluates the rate of filling of the water glass base chemical liquid injected for improving the ground utilizing the fact that this liquid is higher in conductivity than the soil or ground water. An experiment was conducted using a model ground so as to define the limit of applicability of this resistivity tomography by studying electrode arrangements and difference in resistivity between the grouted liquid and ground water. It was then found that the liquid-injected region is evaluated more accurately when the measuring electrodes are installed nearer to the region, that evaluation is satisfactorily accomplished when the region spans not less than 75% of the distance between the electrodes, that higher accuracy is expected when the difference in resistivity is greater between the grouted liquid and ground water, that evaluation is satisfactorily accomplished when the resistivity of the grouted liquid is not more than 10% of that of ground water, and that any grouting liquid usable for ground improvement in civil engineering in urban areas can be applied to any other grounds except where there is influence of seawater. 31 refs., 55 figs., 8 tabs.

Japan-Russia international joint research was made on overhead ultrahigh-voltage DC power transmission lines for transmission loss reduction and reliability improvement, and an optimum international power supply cable system, considering energy saving and environment conservation. Using the European-Russian DC power transmission line of {+-}500kV and 4GW as a model, comparison was made between a model using Russian round strands and glass insulators and a model using Japanese low-loss wires and insulators. As for improvement of the reliability in cold districts, Russian design techniques for tower structure and ice loading were reasonable to counteract galloping oscillation and ice load. In evaluation and selection of optimum underground and marine cables, study was made on cable specifications using the Turkey-Russia power transmission route as a model. The environmental assessment result of these cables showed that XLPE cable under development is optimum. (NEDO)

The results of investigating time management (permissible value of ignition time and prepurge time) for safety control of combustion relating to a combustor is reported. It is shown that the heating value of hydrocarbon-based fuel is determined by molecular weight irrespective of molecular structure and constant (11200kcal/kg) per unit weight; the heating value of mixture gas of theoretical mixture ratio is constant (1000kcal/m[sup 3]) indifferently of the kind of fuel; and that the product of the heating value of a fuel and the lower limit of its explosion limit is approximately constant (400-600kcal/m[sup 3]). Succeedingly it is shown based on these values that allowable ignition time is determined by the combustion chamber load (ratio of the maximum amount, 10[sup 4]kcal/h, of combustion to the volume of combustion chamber); the effect of dilution by exhaust lengthens it by only about 50%; and that the conventional criterion that the frequency of ventilation of prepurge should be 4-5 or that the minimum time of prepurge should be 30 seconds is appropriate. 6 refs., 4 figs., 1 tab.

Reliability and safety are evaluated for main diesel engines, generator diesl engines, their mechatronics and auxiliary machines on ships. The evaluation is based no statistical analysis of field data collected from outland navigation by MO diesel engine the period of 1983-1988. Evaluation indexes are used for analysis, such as failure rate (total number of failure/total navigation hour), mean maintenance man power: mh (total maintenance man power for determined period/total number of failure), manning index: MI (maintenance manpower for repairing failure occurred during 1000 hour navigation). With respect of total failure of ship plant as a whole, the failure rate decreased from 13.2 to 7.4, namely almost to half and mh was tending to increase from 5.5 to 5.8, while MI decreased from 73.0 to 43.1. With respect to heavy failure which is regarded as a scale of safety, the failure rate remained within a range of 0.7-0.5 and mh showed down-up movement like 30{yields}10.4{yields}18.8, while MI moved like 18.6{yields}5{yields} 10.9 . 3 refs., 9 figs., 3 tabs.

An evaluation was given on effects of hydrogen on pipeline materials in order to determine a most base value in an optimal cathodic protection potential in cathodic protection of buried pipelines. Protection potentials were estimated from the relation between critical hydrogen amount and the potentials in marine clays and sodium acetate as electrolyte. The materials were evaluated using a strain rate tensile experiment method. The following results were obtained: The more base the potential, the elongation was somewhat less than the result in air, while the tensile strength increased slightly; difference in water content in soils varies the cross section contraction rate; the rate does not change in a marine clay containing water at 20%, but it decreases in a 30%-content soil; an SEM observation revealed pseudo cleavage faces; and the critical hydrogen amount that causes hydrogen cracking is 10 ppb, which corresponds to -1.4V in a marine clay containing water at 30%, and -1.2V at 14%. A loading experiment with actual loads verified that no fracture due to hydrogen cracking occurs even under an overprotection environment when a load imposed on an actual pipeline is kept constant. 16 refs., 10 figs., 3 tabs.

Performance of a solar heating system with a hydrothermal source heat pump was evaluated and compared with that of a direct solar heating system. The sun-dependency rates ({Sigma}D and {Sigma}H)of the direct system and heat pump (HP)-provided system were expressed as a function of the rate ({alpha}) of the auxiliary heat against the collected heat and as a function of the performance coefficient and {alpha}, respectively. When the sun-dependency rates are compared, it is found that the HP-provided system is the more advantageous when {Sigma}H/{Sigma}D>1. The relationship between the {alpha}`s of the two systems was clarified and computation was performed to compare the sun-dependency rates on condition that the two are equal in the heat collecting area. Although the sun-dependence rate cannot be elevated to 100% in the HP-provided system, it achieves a sun-dependency rate higher than that of the direct system even when the heat collecting area is small. In cases where the building is economically limited, for instance, with respect to the area for solar collector installation, it is advantageous to employ the HP-provided system. 5 figs., 1 tab.

In promoting international collaboration research project, coordination of the patent system of each country which participants to the project belong to has broad implications in concluding the contract for the project. For example, in Japan, 100% of the patent belongs to the government for contrast or collaboration project with the government. While, in the USA, the patent developed by the private company belongs to the private company even for the contrast project. In Japan, the shared patent can not be transferred to the third party or implemented without agreement with the partner. While, in the USA, the shared patent can be transferred to the third party or implemented without agreement with the partner. Due to such a difference, some projects can not be established by ill coordination of intellectual property even when the meaning of the projects is well understood. In this survey, was investigated the outline of patent systems of major countries to study about what should well balanced treatment of intellectual property in international collaboration research project be in the future. 4 figs., 8 tabs.

Interaction between carbon blacks and oxygen molecules has been studied by means of electron spin resonance (ESR) spectroscopy. The ESR spectra of the carbon blacks appears at the g-value of free spin, which are contributed by both isolated electrons and conduction electrons. Upon introducing oxygen to the system the ESR linewidth was broadened in proportion to the partial pressure of oxygen. In case of lampblack (LB 101, Degussa) the interaction was not so strong that it took a tong time at 77K for the linewidth to reach the maxmum value. In case of gassblack (P 140 V, Degussa), on the other hand, the oxygen was easily adsorbed at 298K and the linewidth at 77K became its maximum immediately after cooling. The number of unpaired electrons decreased when the system was kept at 298 K and the decrease was prominent for the local spins. These phenomena have been explained with a simple band model for the electron. (author)

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.

For the assurance of smooth progress of coal technology development endeavors, the New Energy and Industrial Technology Development Organization (NEDO) has installed coal technology development committees (general committee on coal technologies, coal liquefaction committee, plant materials committee, coal type survey committee, total system committee, and coal gasification committee). The coal liquefaction committee deliberates and evaluates liquefaction technology and propels forward smoothly the efforts to develop the technology. Under the coal liquefaction committee, there are four subcommittees, which are the 1st subcommittee (primary liquefaction subcommittee), 2nd subcommittee (solid/liquid separation subcommittee), 3rd subcommittee (secondary hydrogenation subcommittee), and the 4th subcommittee (brown coal liquefaction subcommittee). The 2nd and 3rd subcommittees deal with common tasks as they were studied in fiscal 1980. The 1st subcommittee incorporates into itself the old subcommittees that respectively worked on the three liquefaction processes (the direct hydrogenation process, the solvent extraction process, and the Solvolysis process), and is designed to provide a site for information exchange. A brown coal liquefaction committee is incorporated into the coal liquefaction committee as the 4th subcommittee. This report is a compilation of the agendas of the respective subcommittees of the coal liquefaction committee. (NEDO)

This paper describes a report on the material committee for coal gasification technology development in fiscal 1988. The in-plant test on new materials has performed information investigation on use characteristics and use records of new materials. A sulfurizing corrosion resistance test showed that the aluminum-chromium diffused and permeated material and the molten aluminum plated material stabilize the coated surface and have high corrosion resistance. Ceramics painted lining material was evaluated unusable in a steam diffusion test. Phenol resin was found sufficiently usable as a result of giving the stress test at 100 to 150 degrees C. In developing a let-down valve, a high-velocity water slurry injection test revealed that CVD coating of Ti (C, N) has high effect of suppressing the erosion damage. In a high-velocity powder injection test, PVD coating of TiN and CVD coating of TiC were found to show good erosion resistance. Tests and researches were performed to evaluate durability of furnace materials for manufacturing gasified hydrogen, and elucidate conditions to cause iron oxide burst. Evaluation on repairing techniques, and improvement on durability were also executed. (NEDO)

Described herein are the results of the FY1994 research program for analysis and evaluation of new storage batteries for photovoltaic power systems. Quantitative analysis and evaluation are made for introduction of intermittent operational mode in the conventional power supply system in which electrolyte units are connected in parallel and for improved performance by bubbles flowing into the line that supplies the electrolyte to the stack, in order to establish the configurations of and operational procedures for the redox flow batteries. The study on development of redox battery compares the Pb-Sn alloy felt collector with carbon fiber, Pb-Sb alloy felt and the lattice for the conventional lead acid battery, in order to optimize the new lead felt battery. As a result, it is found that the Pb-Sn alloy felt collector is better than any other device tested, because of its higher freedom with respect to electrode shape and battery size. The study on reliability evaluation of amorphous solar cells tests photoelectric conversion efficiency of a-Si solar cells, in order to elucidate the phenomena where degradation and rejuvenation compete with each other under weak light irradiation conditions. 8 figs., 1 tab.

Described herein are the results of the FY1994 research program for analysis and evaluation of concentrator modules for extra-high efficiency solar cells. The outdoor exposure tests have been under way for 3 years for fluorescent plates, as part of the research program for development of materials and elementary techniques, and essentially no degradation has been observed by the perylene pigment test. Coupling of the fluorescent concentrator and solar cell units is investigated for the coupling position and method, to theoretically analyze geometrical coupling efficiency, where they are coupled at the bottom faces in consideration of easiness of module fabrication. It is demonstrated that a high coupling efficiency can be realized when the cell is sufficiently wide relative to thickness of the fluorescent plate. The coupling method is experimentally examined using transparent silicon gel. A prototype module having the same size as the commercial module (420mm by 960mm) is made on a trial basis, where a total of nine 20mm-thick cells are cut out of a single-crystalline silicon solar cell, 100mm by 100mm in size, and are connected to concentrators at the bottom faces. It shows 2.3 times increased output by the test using a large-area solar simulator. 2 figs.

The paper studied a solar heating system with thermal core type soil heat storage (combining a thermal core composing of a water tank and an underground pebble tank and the soil around the heat storage tank and also using solar energy). Solar energy is stored by temperature level in the high temperature water tank, the low temperature pebble heat storage tank and the soil around the heat storage tank. Heat is recovered according to temperature as direct ventilation space heating (utilization of pebble tank air), floor heating (utilization of hot water of the heat storage water tank) and heat pump heat source (utilization of pebble tank air). A study was made of performance and regional effectiveness of the system under different weather conditions. A study was also made of effects of the water tank for short term heat storage by changing the water volume. Using the same structure, etc. for the system, the system was evaluated using weather data of Sapporo, Tokyo and Kagoshima. In terms of efficiency of the system, the system structure was found to be most suitable for weather conditions in Tokyo. However, the air heat source heat pump which cannot be usually used in the cold area has come to be used. Such effect except efficiency is also considered, and the amount of performance to be targeted in each region changes. 2 refs., 14 figs., 1 tab.

As a method to evaluate the rock mass, electromagnetic tomography and resistivity tomography were tested on the original site. The electromagnetic tomography can tomographically analyze the propagation velocity and initial amplitude damping. The resistivity tomography uses a finite element method from the initial resistivity distribution model and finally gives a model which is nearly equal to the actual resistivity distribution. Both the above tomographic analyses can detect the crushed spot as a low velocity, high damping and low resistivity spot. However, the electromagnetic tomography could detect finer structure than the resistivity tomography. The water content of rock mass was evaluated from the damping coefficient which was given by the amplitude damping tomography of electromagnetic wave. If it is compared with the water content which is given by the dielectric constant of velocity tomography, there partially exists discrepancy between both, because the damping coefficient contains information on cracks which disperse and reflect the electromagnetic wave. Between the resistivity and porosity, there exists a known experimental formula, which was satisfied by the presently given resistivity. 9 refs., 10 figs.

Microcosm system was applied to assess effect of surfactants on aquatic ecosystem. Surfactants such as LAS and Soap were added to an aquatic flask-size microcosm consisting of four species of bacteria as decomposer, one species of ciliate protozoa (Cyclidium glaucoma), two rotifers (Philodina sp. and Lepadella sp.) and one aquatic oligochaete (Aeolosoma hemprichi) as predator, and a green alga (Chlorella sp.) and a filamentous blue-green alga (Tolypothrix sp.) as producer. In the system, NOEC (no observed effect concentration) of LAS was below 1.5mg{center_dot}l{sup -1}, whereas soap was below 30mg{center_dot}l{sup -1}. Microcosm test is a pertinent tool to assess the effect of surfactant on ecosystem because microcosm test makes it possible to evaluate the effect of surfactant from a viewpoint of the interaction of microorganisms, material cycle and energy flow. With these respects, microcosm test is useful environmental assessment method which can reflect aquatic ecosystem. 10 refs., 6 figs., 1 tab.

A discussion was given on value of participation of an IPP as seen from an electric power system operation plan prepared by utilities. In the discussion, evaluation was made using as the breakeven cost of IPP power purchase prices the difference in power generation cost between electric power systems in which an IPP is participating and not participating, or in other words, the reduced portion of the power generation cost. As a result of the discussion, the following matters were indicated: in the case where an utility company expands its capacity by installing a coal-fired thermal power plant which is lower in operation cost, to deal with increase in power demand, the breakeven cost could be an avoidable cost for the utility company; if the expansion by installing a coal-fired thermal plant is not possible, the breakeven cost for a base type IPP would rise; the breakeven cost for a peak type IPP would be higher than for the base type IPP because the breakeven cost can serve to cut the peak for generators owned by the utility company; and participation of an IPP to power sources in remote areas would provide a large effect to reduce power transmission loss in an entire system, thereby increasing the breakeven cost. 1 ref., 9 figs., 3 tabs.

This paper describes a proposal of a method for evaluating environmental performance of technologies by using the interindustry relations table, and the case studies thereof. This method is characterized in that it can evaluate two effects affecting the environment: structuring of capital facilities required in association with introduction of the technologies and the changes in social structures. As a parameter to compare the technologies considering these effects, a concept of life cycle limited emission amount was introduced. In the case studies, life cycle limited CO2 emission amounts from using seven kinds of technologies were calculated, and environmental performances of each technology were compared. The result indicated that introduction in Japan of coal, oil and LNG fired thermal power generation will increase CO2 emission amount from the whole society. Conversely, introduction of hydraulic, nuclear, photovoltaic, and wind power generation technologies will reduce the CO2 emission amount. It is pointed out particularly that hydraulic and nuclear power generation can minimize CO2 emission from structuring capital facilities, and is an excellent technology from a viewpoint of reducing CO2 emission from the society as a whole. 5 refs., 6 figs., 1 tab.

A 70 kW-class photovoltaic (PV) power generation system of the Tsukuba Research Cooperation Center, Agency of Industrial Science and Technology was evaluated using hourly measurement data. Hourly solar irradiation, mean PV module temperature, hourly array generated power, hourly PV system generated power were selected as the measurement items, to examine the validity of measurement method. Furthermore, based on these measurement data, the loss factors were estimated, which reduce the system efficiency. They included the losses due to the shadow effect, the deterioration of module efficiency with the raise of temperature, the mismatch of tracking control of the maximum power point, and the reduction of inverter efficiency with the input power phenomena. To estimate these loss factors from hourly measurement data, the system was evaluated by defining characteristic parameters. As a result, it was found that the main factors were the shadow effect and the mismatch loss, which reduce the mean annual output factor of the system to 65%. 3 refs., 6 figs., 1 tab.

With an objective of evaluating the contribution to the global environment of utilization of photovoltaic power generation, discussions were given on evaluation of photovoltaic system life cycle, evaluation of contribution to environment, and total evaluation. This paper summarizes the achievements in fiscal 1999. In evaluating the PV system life cycle, the roof-integrated modules using the thin film CdTe cells were selected as the evaluation object to estimate the energy payback time (EPT) and the CO2 emission unit consumption rate. In case of annual production of 10 MW, the EPT is 1.8 years and the CO2 emission unit consumption rate is 13 (g-C/kWh), which were found largely reducible by expanding the annual production size. For the environmental contribution evaluation which focuses on CO2 emission suppression effect as the discussion object, discussions are being given on the introduction scenario needed for the analysis. In the total evaluation, the direct employment effect assumed in Japan was discussed on production, distribution sales, installation, maintenance control and dismantling of photovoltaic generation system for residential use. The discussion showed the effect of about 7 persons per year per MW in production size of 100 MW. (NEDO)

Efforts were made to develop methods for evaluating the characteristics of metallic materials experiencing high-speed deformation or impact deformation. The research was conducted by the research WG (working group) consisting of some participants of an international conference convened this fiscal year. The research result revealed that studies in Japan lopsidedly dealt with metallic materials at strain velocity of 10{sup 4}/second or less, such as steel, while many studies overseas dealt with materials other than metals at strain velocity over 10{sup 4}/second. The test and evaluation WG conducted high-speed tension tests for T6-treated aluminum alloys using the split Hopkinson bar method, hydraulic servo method, one bar method, and the sensing-plate method for measuring force, and the results were compared. It was then found that the one bar method produced disturbance more remarkably than the others and that the loading block structure and load rise time influenced the emergence of the peak load. The emergence of a peak load in the Hopkinson bar method or the one bar method had been predicted on the basis of the research conducted by the analysis group. (NEDO)

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 effort aims to develop a sensor system to enable overall VDC (vehicle dynamic control). The goal is to manufacture a small module type sensor system more than 20 times higher than the conventional type in responding speed and accuracy, which will use a novel ABS (anti-lock braking system) capable of direct and real-time measurement of axial forces in the four directions. The prototype module will be a package in which a system-on-a-chip accommodating peripheral circuits is integrated with a sensor. In the effort to develop a novel multi-axial sensing system (MASS) for a smaller ABS, a circuit optimization technology was developed. A dedicated IC (integrated circuit) was developed for a system to process a large volume of signals. In the effort to develop technologies for packaging the novel sensor system and for constructing modules, technologies were developed for integrating sensor components and an IC into one, module junctioning, module installation, simplification of the installation process, and for the manufacturing of modules. Developed in the effort to optimize MASS were technologies involving the selection and evaluation of sensor components and the enhancement of such processes, optimization of the sensor itself, and the improvement of the sensor system for higher efficiency in calculation. Sensor modules were tested aboard vehicles and the compatibility of the system-on-a-chip with the MASS module was confirmed. (NEDO)

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

To manage and promote the progress of research at the National Institute of Bioscience and Human-Technology where the centralized management of this project is conducted, meetings are held once a month to examine the progress at the institute, in which reports are made and discussions are held on how each research item is progressing. In addition, meetings of the committee to promote research are held every other month to consider and examine measures required for promoting the research. Re-entrustment of research has been made on two subjects, i.e., `Studies on biological significance of symbiotic microorganisms` by Prof. Ishikawa of the University of Tokyo, and `Study on the relationship between the biosynthesis of useful terpenic materials of plant origin and the differentiation of plant tissues, and their effective production by plant cell cultures` by Prof. Inoue of Gifu Pharmaceutical University. 27 refs., 13 figs., 1 tab.

Research was made on electronic NEDO research reports corresponding to the recent extending trend of Internet. The logical structure and electronic format of NEDO research reports as document were first studied considering document disclosure and reuse of technical information. HTML as electronic format for Internet is unfortunately insufficient to describe the logical structure of NEDO research reports because of HTML's restricted description. Thus, XML which is being watched because of its possible definition of original tags was studied in place of HTML. As a result, because at present preparation of standards on XML and a compatibility for implementation of standards are insufficient, it was concluded that construction of the electronic document system for NEDO research reports is still too early. However, since adoption of XML as document format is important from the viewpoint of a property succession on Internet, preparation of the XML format file of NEDO research reports is essential.

This paper reports the activities of the coal type committee in fiscal 1992, and summarizes the main technological achievements. In the Chinese coal liquefaction test, fiscal 1991 has performed liquefaction tests on Fushun coal by using a small continuous testing facility (0.1 t/d) at the Coal Chemistry Research Institute in Beijing. Fiscal 1992 has completed the liquefaction tests on Shengli coal. In October, a liquefaction test was carried out by using Tianzhu coal according to the NEDOL process. This paper reports the result of the liquefaction test on the Shengli coal, and the result of the analysis on the Fushun coal liquefied oil. The coal type selection and investigation having been performed to date reveals close correlation among the maceral composition of coal, coal rank and liquefied oil yield. Coals having good reactivity and suitable for liquefaction are generally suitable also for gasification. In the pretreatment of coal as a gasification material for hydrogen manufacture, a test was performed by using A heavy oil and tar sand bitumen plus A heavy oil as the granulating agents. With Montana coal, the highest de-ashing rate was achieved when the oil was added at 35% by weight. Both of the reaction rate and oil yield were improved. A handling test was carried out up to 72.5 degrees C, wherein Tatung coal presented no problems in both of the discharging and sticking tendencies. (NEDO)

Chlorinated organic compounds has high priority for toxicity screening among environmental hazardous chemicals. In the present study, we used immortalized rat hepatocytes as a liver model in vitro to evaluate the toxicity of nine chlorinated organic compounds. Toxicity of nine chlorinated organic compounds were evaluated to cellular viability of immortalized rat hapatocytes. The potency of the toxicity based on 50% inhibitory concentration (IC50) value was in the following order: triclocalban>triclosan>3,4-dichloroaniline>2,5-diclorophenol> 2,5-dichloroanisole>p-dichlorobenzene> p-chloroaniline>o-dichlorobenzene=tris (2-chloroethyl) phosphate. The rank order of cytotoxic potency of nine chemicals was compared with toxicity information using animals. The rank order of cytotoxic potency did not relative to the order referenced mean lethal dose (LD50) as an index of acute toxicity of rats or mice. However, the rank order of cytotoxic potency relatively correlated non-observed adverse effect level (NOAEL) under the exposure duration adjusted for chronic toxicity in vivo. These data suggests that the origin of testing cell had better to make match target organ of toxic chemicals for extrapolation from data of bioassay in vitro to in vivo. 16 refs., 2 figs., 3 tabs.

In this paper, we propose the State Grouping scheme for coping with the problem of scaling up the Reinforcement Learning Algorithm to real, large size application. The grouping scheme is based on geographical and trial-error information, and is made up with state generating, state combining, state splitting, state forgetting procedures, with corresponding action selecting module and learning module. Also, we discuss the Labeling Based Evaluation scheme which can evaluate the opportunity of the state-action pair, therefore, use better experience to guide the exploration of the state-space effectively. Incorporating the Labeling Based Evaluation and State Grouping scheme into the Reinforcement Learning Algorithm, we get the approach that can generate organized state space for Reinforcement Learning, and do problem solving as well. We argue that the approach with this kind of ability is necessary for autonomous agent, namely, autonomous agent can not act depending on any pre-defined map, instead, it should search the environment as well as find the optimal problem solution autonomously and simultaneously. By solving the large state-size 3-DOF and 4-link manipulator problem, we show the efficiency of the proposed approach, i.e., the agent can achieve the optimal or sub-optimal path with less memory and less time. 14 refs., 11 figs., 3 tabs.

The objective of this investigation is to estimate the creep life of glass fiber reinforced plastic (GFRP) under stress-corrosive environments using acoustic emission(AE). The laminates were fabricated using combinations of vinylester resin (R806) and random fiber mat or woven cloth. The creep tests were conducted in 5% nitric acid (HNO{sub 3}) environment. The AE depends on the loading level and the environment condition. For the creep test, the woven cloth reinforced specimens gave higher number of AE counts than the random mat reinforced specimens. The creep life decreased with increasing creep stress, whereas the rate of AE counts increased with increasing creep stress. A linear relationship was found between the creep life and the AE count rate. Using the proposed equation, a prediction of the creep life of GFRP under corrosive environments would presumably be possible. (author)

Ikeda, et al., in their examination of log data obtained from a borehole (2000m deep) drilled at Ashio, Tochigi Prefecture, where micro-earthquakes swarm at very shallow levels, pay special attention to porosity. Using correlationship between the porosity and elastic wave velocity/resistivity, the authors endeavor to find the presence of secondary pores, dimensions of faults, composition of water in strata in faults, and difference in matrix between rocks, all these for the classification and evaluation of fault fracture zones. In the present report, log data from a borehole (1800m deep) drilled to penetrate the Nojima fault (Nojima-Hirabayashi, Awaji island) that emerged during the Great Hanshin-Himeji Earthquake are analyzed in the same way as the above-named Ashio data, and the results are compared with the Ashio results. Immediately below the Nojima-Hirabayashi fault fractured zone, stress is found remarkably reduced and the difference stress quite small in size. This is interpreted as indicating a state in which clay has already developed well in the fault fractured zone ready to allow the occurrence of shear fracture or a state in which such has already occurred for the release of stress. 4 refs., 5 figs.

The computer aided coal structure construction system is proposed, and a computational construction example is presented. The coal structure construction engine of this system fabricates molecular structure by connecting fragments sequentially inputted through a user interface. The best structure candidate is determined using construction knowledge and partial energy evaluation every addition of one fragment, and this process is subsequently repeated. The structure evaluation engine analyzes the 3-D conformation candidate by molecular dynamics, and evaluates the conformation by determining the energy value of an optimum structure. As an example, this system was applied to construction of coal molecular structure based on the actual data of partial structure composed of 26 structures from 2l kinds of aromatic cluster structures, 27 bonds from 2 kinds of bridged bonds, and 16 groups from 2 kinds of terminal substitutional groups. As a result, this system could construct a superior structure according to expert knowledge from the viewpoint of energy. 6 refs., 5 figs., 2 tabs.

Summarized in this report is the material already distributed concerning the program for modifying the Nakoso 200t/d pilot plant entrained bed coal gasification furnace. The program aims to verify the overall suitability for power generation use of the air-blow pressurized 2-chamber 2-stage flow entrained bed gasification furnace. Although each specific feature of gasification furnace performance is found to be satisfactory, yet a 100% operation and extended continuous operation remain to be accomplished. Slagging is a phenomenon of ash grains in high-temperature gas adhering to and growing on the furnace walls to block up the furnace to eventually disable the furnace from continuous operation. In view of past achievements and test results, it is found that slagging is closely related to the behavior of floating or molten ash and to the transition temperature range. Various slagging measures have been taken for the current gasification furnace, but they prove to be ineffective. Some drastic measures need to be implemented for improvement. Under study using model furnaces and test furnaces are the reduction of slag generation at its source (re-entrained slag), prevention of adhesion (untrapped slag), removal of slag, optimization of gyration in the furnace, modification of slag properties for enhanced discharge, optimization of the transition gas temperature range, and the modification of furnace dimensions.

This paper reports a joint meeting of the coal liquefaction committee and the coal type committee in fiscal 1993. The report is focussed on the coal type selection (the final report) for the coal used in the 150-t/d coal liquefaction pilot plant (PP) among other agenda. Initially the Australian Wandoan coal was scheduled to be selected as the reference coal for the PP operation, but the mine has not gone into operation, hence the schedule was given up. Screening was carried out to select a coal which is commercially produced and exported, and contains ash at 10% by weight or less, sulfur at 1.5% by weight or less, and chlorine at 300 ppm or less. An autoclave and a 0.01-t/d flowing type device were used to evaluate liquefaction performance, whereas the Tanito Harum coal produced in Indonesia, very similar to the Wandoan coal, was selected as a promising candidate. A PSU was used to demonstrate overall operation performance. The coal is an appropriate reference coal as seen from the aspects of liquefied oil yield, nature, operability, and site surveys in Indonesia. Among the actual record of four kinds of PSU coals in the past, the present coal has the oil yield ranked high, has the least liquefaction residues, and is advantageous economically. The oil yield per ton of coal has cleared the PP target of four barrels. The coal has less ash, is easy in solid/liquid separation in the depressurized distillation, and has no problems in operability, excepting the matter of coal supply. (NEDO)

This is a summary primarily of the distributed material. As of December 14, 1995, the 200t/d pilot plant for power generation by entrained bed coal gasification records a total coal gasification operation time of 4,485 hours with an accumulated amount of power generation of 9,227MWh. A large combustor is tested, and it is found that combustion is stable under a 1/4 load with low NOx emissions. The combustor is sufficiently cooled with a small supply of air. Coal ash and coal, supplied in a constant state for an improved heat recovery efficiency in the development of hydrogen-from-coal technology, are heated to a temperature near their melting points. They are then allowed to impinge at a heat transfer plane simulating a gasifier heat recovery section, and a study is made of the mechanism of ash adhesion, molten or semi-molten, to the heat recovery section. The reduction of the heat transfer coefficient due to added grains is 30-50%, and the reduction is small when the heat transfer pipe surface velocity is high or when the carbon concentration in the grains is high. In another effort, utilization of coal-derived gas as town gas is studied. As for yields as indicated by the Curie gas pyrolyzer, the gas yield increases and liquid yield decreases when the reaction temperature is high. Using a small test unit, it is found that a rise in the hydrogen partial pressure increases the production of both gas and liquid. (NEDO)

Summarized herein are results of the studies on closed cycle MHD (CCMHD) power generation by the study committee. The studied system is based on the MHD gas turbine combined Brayton cycle of about 500,000 kW in output power, firing natural gas as the fuel, and the conceptual design works therefor are completed. The major findings are: the overall plant efficiency: 54.2% at the power transmission side, plot area required per unit power output: 0.04 m{sup 2}/KW, unit construction cost: 251,000 yen/KW, and unit power generation cost: 10.2 yen/KWh. This system will be more operable than the gas turbine combined cycle with steam system, because start-up time, output change rate, optimum load and so on are constrained not on the power generator side but on the gas turbine side. The expected environmental effects include the exhaust gas NOX concentration being equivalent with that associated with the conventional power generator of 2-stage combustion system, quantity of combustion gases to be treated being approximately 40% of that associated with the gas turbine combined cycle, and reduced CO2 gas emissions, resulting from enhanced power generation efficiency. It is expected that the CCMHD system can exhibit higher efficiency than the high-temperature gas turbine combined cycle system. (NEDO)

This paper reports the result on R and D of the femtosecond technology in fiscal 1997. Ultrahigh-speed electronic technology is indispensable for industrial basic technologies supporting the advanced information society in the 21st century. Control technology of photonic and electronic states in a femtosecond region is essential. In R and D of metrological technology using ultra-short light-pulses, study was made on generating and controlling technology for ultra- short light/electron beam pulses. Ti-sapphire mode-locked laser was prepared, and it was found that time-fluctuation of mode-locked laser pulses is measurable up to 100 femtosecond level. As measures against an instability of gain-switching semiconductor laser, light injection from the outside was effective. The stable directivity of laser beam was obtained by regenerative amplifier, while less temperature variation of an optical switch was necessary to stabilize energy. To generate femtosecond high-intensity X-ray pulse by collision of laser and electron beams, it was confirmed that sub- picosecond synchronization is possible by RF and picosecond laser synchronization circuit. 48 refs., 89 figs., 11 tabs.

As the first step for the introduction of wind power systems and photovoltaic power systems into developing countries in Southeast Asia etc. and for their diffusion in them for the exploitation of natural energy, a numerical weather model useable in Southeast Asia is developed to make up for the insufficiency of weather data in the region. A technique is developed, to explain which the case of Myanmar is cited, for estimating with accuracy such natural conditions as wind direction, wind velocity, and solar radiation in the past one-year period for the assessment of power to be generated using wind turbines and solar panels. The results of the observation of wind conditions indicate that wind directions are mainly northerly or westerly and that wind speeds are as week as 1-3m/s on the average. As for total solar radiation per diem in December through March, it is found that there is 17-23MJ/m{sup 2}/day, which is twice the level to be measured in Tokyo. A comparison is made between the weather observation results and a model calculation, and it is found that the latter sufficiently reproduces the actual weather conditions. Based on the values of wind conditions and solar radiation estimated in Myanmar, the amount of power to be obtained from an assumed arrangement of wind power systems and solar panels is assessed.

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

Research and development is conducted for the acquisition of a system evaluation technique for predicting the performance of standard photovoltaic power systems and evaluation technologies applicable to residential photovoltaic power systems different from each other in terms of tilt and direction, district, solar cell type, etc. In fiscal 1999, using data collected from the Hamamatsu field test facilities and residential photovoltaic power systems installed across Japan, various design parameters, such as the irregularity compensation coefficient, temperature compensation coefficient, and the incidence compensation coefficient were determined, and, using the parameters as the secondary estimation values, design parameters were updated. In the development of simulation technologies, basic studies were made about the shadow compensation coefficient, spectral response fluctuation compensation coefficient, and the composition of polyhedral arrays. Moreover, studies were made about the estimation of large area insolation, based on the horizontal surface insolation data collected at 21 sites of residential photovoltaic power systems in the Kanto district.

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

In order to construct real sustainable global environment and human society in the 21st century called the century of environment, not only the innovation of manufacturing processes technically supporting such the construction but also the conception including the innovation of the whole society from a wide viewpoint are essential. As a total energy and material control system (TEMCOS) concept, the view of an energy-saving circulating society is attempted which minimizes a total energy and material flow in Japan, and the role and issue of manufacturing industry, in particular, material industry are extracted. As one of the targets of such a concept, the conception of an eco-town is also described. Paying attention on some important material industries including a mass material flow and consuming a large amount of energy such as metal, plastics and automobile industries, the study result on a material flow for every industry is arranged, and some effective issues contributing to minimize a material flow and control energy consumption and CO2 emission are extracted. 80 refs., 67 figs., 30 tabs.

For the purpose of studying an expanse and characteristics of the geothermal system and a possibility of geothermal development in the Haneyama area, Oita Prefecture, geochemical survey was conducted. In the survey, various kinds of analyses were made for 13 specimens of hot spring water and 5 specimens of surface water in the area of about 280km{sup 2} at 402 measuring points of the concentration of Hg in soil gas. The results of the survey were as follows: In this survey area, it was thought that the HCO{sub 3} type geothermal water of a comparatively low temperature which was heated by the wide-spread conduction heat from the depths was widely distributed deeper than the depth of 500-700m, and it was presumed that a possibility was low of existence of a high geothermal potential which can be used for the geothermal power generation in the part deeper than the drilling depth of 700m. In the Noya area in the southwest part of the survey area, the high temperature deep geothermal reservoir was confirmed. In this area, the high temperature neutral-alkalescent Cl-SO{sub 4} type geothermal water was distributed in the depth of several 100 meters or deeper. The geothermal water seemed to flow from NE to SW along the structure in the NE-SW direction, and it was concluded that the area was the most promising one. (NEDO)

Study was made on promotion of CDM (clean development mechanism) project through technology transfer with plant exports. Although CDM system was provided in COP3 on climate change held in Kyoto in 1997, its detailed rules including project approval are yet undecided, and only the schedule to provide the detailed rules until COP6 in 2000 was decided in COP4 in 1998. The common recognition that the CDM project with plant exports produces various merits for both Japan and the partner country is increasing. However, from the viewpoint of forming concrete CDM projects, most Japanese enterprises are passive in approach to the CDM project because of no detailed design of CDM, uncertain profitability and procedures, and avoidance of additional burdens. Plant export is also difficult because of the fact that assessment of a new project is difficult. Enterprises' deeper recognition on the CDM project, and a governmental integrated support system are desirable. (NEDO)

For the contribution to elucidation of the geothermal structure in the Haneyama area in Oita Prefecture, gravity prospecting was conducted. Survey was carried out in the area of about 280km{sup 2} at 205 measuring points, and analysis was made altogether with the existing 3,273 gravity measuring points. As a result, the following were made clear. The gravity basement forms the fault-state structure that sinks several 100 meters to the south side on the line from the south edge of the Higashi-shiiya ridge to Mt. Kurotake - Mt. Daigansen - Amagase hot spring in the SW direction. This fault was made correspondent to the Beppu north fault on the east side of Mt. Kurodake. Each of the following regions is the region where the fault-state structure that predicts the development of fracture and the area of distribution of alteration zone that can be cap rock overlap each other: NW edge of Shishimuta sedimentation zone - Machida alteration zone distribution area; N edge of the Shishimuta sedimentation zone - Ibushi alteration zone/Noya alteration zone distribution area; Vicinity of Mt. Kurodake - Hijiu alteration zone distribution area. It seems that the above-mentioned regions have high potentiality of geothermal exploration. The region where new igneous activities are seen, which is near the heat source, is important for exploration. The distribution area is seen near the west of the Mizuwake Pass ridge. (NEDO)

This paper reports model experiments to evaluate flow rates of fluids passing through a fracture by using a Doppler borehole televiewer (DBHTV). A supersonic transducer disposed on a well axis transmits transmission pulses, and a transducer receives scattered waves generated by particulates in water and waves reflected on a well wall. This signal is applied with time gating to extract only the scattered waves from particulates in the vicinity of the well wall. Deriving spectra in the recorded Doppler signal obtains flow velocity components in the direction of the well radius. A model was made with a polyvinylchloride pipe with a diameter of 14.6 cm to simulate a well, to which an aluminum pipe with an inner diameter of 2 mm is connected to be used as a simulated fracture, and mud water is circulated in the pipe. The result of deriving a passed flow volume in this model by integrating flow rate distribution derived by using the above method to a predetermined range in the vicinity of the fracture showed a good proportional relationship with actual flow rate in the simulated fracture. 1 ref., 7 figs.

Discussed is a method for evaluating wind noise in passenger car compartment based on human auditory characteristics. In the study, noise in the compartment of a passenger car travelling at a constant speed is collected by use of a dummy head, and the collected noise is analyzed in view of the masking effect, directional sensation produced by binaural hearing, etc. A masked spectrum of noise in the compartment of a 6-cylinder vehicle travelling at 120km/h is analyzed, and it is found that some frequency bands, especially the band centering on 300Hz, are masked by a loud noise component falling in a low frequency band of 180Hz or lower. By use of masked spectrum analysis, the level of noise that is actually audible to human ears can be calculated. The noise level thus determined by masked spectrum analysis and the noise direction determined by a binaural signal processing model are examined, and then it is found that the noise direction is clearly determined when the noise belongs in a 450Hz band or higher where wind noise prevails. On the bases of the above-mentioned results and the directional sensation produced by binaural hearing, a `binaural wind noise evaluation method` is compiled. 20 refs., 9 figs., 1 tab.

The abnormal sisal, which was observed in the ESR measurement of superconductors, was confirmed to be a non-ESR (non resonant) signal, from an ESR experiment applying parallel and vertically polarized microwave fields and from the calculation of the ESR transition probabilities. The field modulation dependence of the spectra revealed that the signal was composed of two components. From the modulation-scheme analysis and a study of type I and II superconductors, two components were assigned to the microwave responses to magnetizations trapped in the crystalline portion and at intergranular Josephson junctions. The former B and the batter J components are observed in the first derivative and absorption a form, respectively, and their polarities differently behave for the field sweep reversal. Based on these results, we have improved an ESR spectrometer, which makes it possible to measure separately two kinds of magnetization and to study the trapping ability and quantum flux. 11 refs., 12 figs., 1 tab.

The ability that architectural space improves the thermal environment in comparison with outdoor environment is called the `capability of controlling thermal environment.` As the value becomes higher, the indoor thermal environment is more improved. In this paper, the controlling capability of six building envelopes with different window systems was compared. The heat transfer in the wall and window system is approximated using a lumped mass model of heat capacity to obtain a heat balance equation and combined with the heat balance equation in indoor air for backward difference. The wall surface temperature and indoor air temperature in a calculation model are then calculated. A radiation absorption coefficient is used for mutual radiation on each wall. In the model, the adjoining room or first- and second-floor rooms were made the same in conditions as the model on the assumption that the one-side lighted office in an RC reference floor is in the non-illumination and non-airconditioning state. In summer, the controlling capability remarkably varies depending on the window system. For the window facing the south, the annual capability is more advanced than in other directions and the indoor thermal environment is improved on the average. 7 refs., 12 figs., 1 tab.

To know the trend of measures taken for global warming, conducted were overseas surveys, participation in academic society meetings, and literature surveys. The phaseout time of all ozone depleting substances responsible for the ozonospherial destruction was determined for both developed and developing countries in the 7th Meeting of countries which concluded the Montreal Protocol. As information on measures for protecting the ozonosphere, introduced was activities under United Nations Environment Programme (UNEP). New fluorine containing ethers were introduced as cleaning solvent which causes no ozonospherial destruction and is low in global warming index. Toxicity data were obtained on HFC-236ea and HFC-236fa which are promising substitutes in HCFC foaming and refrigerant fields. The paper introduced an outline of the 1st Meeting of countries which concluded the Framework Convention on Climate Change held in 1995. According to the report on the National Institute of Public Health and Environmental Protection of the Netherlands, the amount of emission of fluorine containing greenhouse effect gas (in CO2 conversion) reached 8-14% of all the amount of greenhouse effect gas emitted in 1990 unless the control is reinforced. An outline of the TEWI-3 project was introduced which is useful for comparing effects of substitution technologies on global warming. 14 refs., 11 figs., 29 tabs.

Because of an increase in energy demand due to economic growth and industrial structure change in the Asian area and its effect on global environment, the economic evolution harmonizing with energy and environment (3E) of the Asian area is required. The role of Japan, in particular, NEDO for achieving such 3E was studied from an international viewpoint. The following are thus surveyed: The history of energy demands, economic growth, an increase in energy consumption and their effect on global environment in the Asian area, and the policies, measures and future plans of Asian countries corresponding to the above situations. The role of NEDO is first of all R & D of biomass toward practical use, and development of effective use technology of biomass energy. Positive approach to control of CO2 emission and immobilization of CO2 is also required in industrial and traffic fields. As technology transfer from Japan, promotion of joint researches and establishment of an economic support scheme are expected together with transfer of the basement technology and training. 79 figs., 13 tabs.

Evaluations were given on spatial resolution and measurement time of an optical tomographic system by using the developed 64-channel time-resolved spectroscopy and an image reconstruction algorithm. With respect to the spatial resolution, the target value of 1 cm was verified from tomographic images of a phantom with a diameter of 10cm, simulating a neonate. The measurement time achieved 20 minutes, being one third of the target value. In installing the equipment at Hokkaido University, speeds of the optical switches and attenuators were increased to have reduced the measurement time to one minute. For installation at Kanagawa Rehabilitation Center, development has been made on a nano-second light pulser, whose average beam quantity has been increased to 40 times, and improvement has been given on the optical switches, the attenuators, and the indication software, by which the measurement time was decreased further by 30 seconds than that at Hokkaido University. In performing the clinical evaluation, the evaluation protocol resolved by the Experiment Evaluation Special Committee was submitted for deliberation at the Medical Welfare Device Clinical Evaluation Committee. Upon having been authorized by the Committee, the clinical evaluations were performed at Hokkaido University and the Kanagawa Rehabilitation Center. (NEDO)

Arrangement, investigation and analysis of an energy information exchange system were conducted, with the aim of coping with the development in the whole Asia/Pacific area, the stabilization of energy supply/demand, and the environmental problem and of realizing effective cooperation of every country in the area. Concerning the trend of the domestic primary energy supply/demand, there are some patterns. Countries which show high growth rates are developing countries such as Thailand and China, and NIES such as Korea and Taiwan. Countries where growth rates are slowing down and lowering are developed countries such as Australia, Canada, Japan and the U.S. Countries where energy supply/demand is not stabilized are Singapore, Hong Kong, Indonesia and Chile which are suffering from variations in import/export. The ultimate energy consumption is the domestic primary energy supply from which the conversion loss in the conversion sector was deducted, and indicates almost the same trend as the primary energy supply. It is divided into a stabilized type of developed countries and a rapidly increasing type and a stagnant type. However, there are some exceptions. Total data in the quarter of the year cannot be the yearly data by itself, but requires a year-end tax arrangement. 40 tabs.

Described herein are the results of the FY1994 research program for analysis and evaluation for development of extra-high efficiency silicon solar cells. It is necessary for development of extra-high efficiency Si solar cells to extend as far as possible service life of minority carriers and to develop the evaluation techniques. Noting photoluminescence (PL) observable even with Si, the method of evaluating characteristics of minority carriers, which are not limited in samples, is developed to experimentally determine their service life from transitional response of the PL characteristics. Si has an extremely low quantum effect, because it is an indirect transitional semiconductor, and needs measurement of very high sensitivity. A rapid heat annealing apparatus and others to generate carriers in the infrared and ultraviolet regions are provided in consideration that these are possible means to increase efficiency. These possibilities will be pursued by developing the annealing techniques. 1 fig.

With an objective to know coal condensation structure which has influence on coal conversion reaction, an attempt was made on quantitative evaluation of hydrogen bonding in coal. Using as test samples the VDC made from Taiheiyo coal swollen by tetralin and vacuum-dried, and its pyrolyzed char, DSC measurement and Fourier transform infrared spectroscopy (FT) were performed. An FT spectrum comparison revealed that the VDC swollen at 220{degree}C has the hydrogen bonding relaxed partly from the original coal. However, since the change is in a huge coal molecular structure restraining space, it has stopped at relaxation of the bonding energy without causing separation as far as free radicals. On the other hand, the DSC curve shows that the VDC has slower endothermic velocity than the original coal. In other words, the difference in heat absorption amounts in both materials is equivalent to the difference of enthalpy ({Delta} H) of both materials, which corresponds to the relaxation of the hydrogen bonding. Therefore, the {Delta} H was related to wavenumber shift of the FT spectra (which corresponds to change in the hydrogen bonding condition). By using this relationship, a method for evaluating hydrogen bonding distribution was proposed from an O-H contracting vibration change that can be measured by using the FT spectra and a thermal change that can be measured by using the DSC. 3 refs., 7 figs.

Performance of various catalysts for hydrogenation of recycle solvent was evaluated for the operation of NEDOL process 1 t/d process supporting unit (PSU). Distillate between 220 and 538{degree}C derived from the liquefaction of Tanito Harum coal was used as recycle solvent. Deactivation behaviors of catalysts were compared using a prediction equation of catalyst life, by which aromatic carbon index (fa) after hydrogenation can be determined from the fa of recycle oil before hydrogenation, reaction temperature, and total hydrogenation time. Total hydrogenation time satisfying the {Delta}fa, 0.05 before and after hydrogenation were 8,000, 4,000, and 2,000 hours for NiMo-based catalysts C, A, and B, respectively. Catalyst C showed the longest life. Used catalysts were also characterized. The catalyst C showed larger mean pore size than those of the others, which resulted in the longer life due to the delay of pore blockage. From measurements by XPS and EPMA, relative atomic concentration of carbon increased remarkably after the use for all of catalysts, which was considered to be due to the adhesion of hydrocarbons. Increase of metal atoms, such as Fe and Cr, was also observed due to the contamination of entrainment residues. Deactivation of catalysts was caused by the adhesion of hydrocarbons, and metallic compounds, such as Fe and Cr. 3 refs., 1 fig., 5 tabs.

CO2 emission was quantified through the life cycle of a solar water heater to assess its environment impact. Although LCA (life cycle assessment) originally sums up I/O of all materials and energy through the whole life cycle of a product to examine environment impact, this assessment was carried out for only CO2. Calculation of CO2 emission assumed a natural circulating solar water heater of 200 l in effective hot water capacity, 2.78m{sup 2} in effective collecting area, and 0.5 in average annual collecting efficiency of total solar radiation, and an auxiliary city gas heat source for compensating insufficient heat quantity. The total CO2 emission in the life cycle of a solar water heater was obtained from an industrial association table assuming the life cycles of 10 and 20 years. CO2 emission was estimated to be 5407.1kg-CO2 and 10665.2kg-CO2 for 10 and 20 years, respectively. CO2 emission due to city gas was largest in the total CO2 emission in the life cycle. As a result, for reduction of CO2 emission due to a solar water heater, improvement of equipment efficiency was most important. 6 refs., 5 figs., 3 tabs.

The engine structure attenuation has been experimentally analyzed by the newly developed in-cylinder excitation system. It can reproduce the complete cylinder pressure in non-running engine conditions by adopting the hydraulic and the piezoelectric actuator. The structure attenuation measured in this system has a good coincidence with the ones measured in actually engine operating conditions, meanwhile the current method, which applied only high frequency components as the excitation pressure, was shown to have the unsatisfied agreement. As a result, the proposed system has been concluded to be very useful to estimate the engine noise characteristics in non-running conditions. 4 refs., 11 figs., 1 tab.

Microcosm system was applied to assess effect of anionic surfactant (LAS) on aquatic ecosystem. Anionic surfactant such as LAS was added to an flask microcosm consisting of four species of bacteria as decomposer, one species of ciliate protozoa (Cyclidium glaucoma), two rotifers (Philodina sp. and Lepadella sp.) and one aquatic oligochaete (Aeolosoma hemprichi) as predator, and a green alga (Chlorella sp.) and a filamentous blue-green alga (Tolypothrix sp.) as producer, comparing with that of an natural lake model ecosystem derived from natural lake water. In the flask microcosm system and the natural lake model ecosystem, biodegradation rates of LAS were almost same and NOECs (no observed effect concentration) of LAS were also below 1.5 mg{center_dot} l{sup -1}. It was found that flask microcosm test could provide precise ecological effect assessment of LAS on number of microorganisms because the system showed higher reproducibility and stability than natural take model ecosystem. It was suggested that flask microcosm test was useful ecological effect assessment method which can reflect natural aquatic ecosystem. 10 refs., 4 figs., 2 tabs.

Remote sensing images include information of coastal land division, sea level change such as sedimentary environment and vegetation, and distribution of artificial structures. Past sea level changes and their causes can be regionally obtained by analyzing these data and by integrating them with information obtained from geological survey. In this study, causes and history of past sea level changes, formation mechanism of coastal topography, and past sea level change survey in Thailand have been reviewed. This paper describes an extraction method of the sea level change information in coastal districts by analyzing several actual remote sensing images. For understanding the current sea level rise, it is required to clarify the causes quantitatively among three causes of sea level changes, i.e., volumetric change of total ocean water on the earth, relative sea level change due to the crustal deformation, and change of irregularity of sea surface with ocean current. It is also required to compile maps in Asian or global scales. 13 refs., 6 figs.

Desktop video conferencing (DVC) system and its software were investigated. A test system was actually constructed. Based on the test results, its practical advantage and disadvantage were illustrated. The DVC system was constructed using general LAN, and operation experiments were conducted, as to research activity. From the interview with participants and analysis of conversation history, advantage and disadvantage of this system were clarified. Performance of the trial system was examined using practical LAN, to compare with the performance of commercial systems. When using LAN, the same problems were given. It was found that the DVC system can not substitute for the conventional real face to face meeting, but it is suitable for some communication styles, for example free participation meeting or collaboration based on the same objective, which has been hard up to this time. In addition, software was made as trial, by which reservation of meeting, announcement, and calling can be carried out. 26 refs., 6 figs., 5 tabs.

A regression equation that can calculate the daily accumulated absorption heat of Trombe Wall was given, and the performance estimated chart of Trombe Wall in which the daily unit effect of Trombe Wall can be visually recognized was proposed. The absorption heat was multivariate-analyzed by two variables of solar radiation of that day and the previous day. The data obtained from simulation was used for analysis. The absorption heat was analyzed using the meteorological data at eight spots (Sapporo, Sendai, Niigata, Tokyo, Shizuoka, Kochi, Fukushima, and Kagoshima). In this case, the result of multivariate analysis almost coincided with the simulation result. A chart that predicts the absorption heat of Trombe Wall in eight cities from the daily accumulated global solar radiation of that day and the previous day was then created as the performance estimated chart of Trombe Wall. As a result, the solar radiation of that day little influences the absorption heat when the Trombe Wall increases in thickness. Conversely, the solar radiation of the previous day significantly influences the absorption heat. In future, an equivalent heat loss coefficient will be calculated from the performance estimated chart. 2 refs., 16 figs., 2 tabs.

We have proposed the 'complementary menu system' as an easy-to-build and easy-to-use menu system. It has two component menu systems, one is based on a word taxonomy and the other is based on the document structure (e.g., the table of contents of the target document). By the user's selection of an item on a menu, the positions and relevance of related items are shown on the other menu, which makes users easier to select proper menu items. We have also shown the combination of context-sensitive menus reduces user's errors of selection of menu items by several experiments. In this report, we investigate the choice of word taxonomies effective for novice users and the design of structure and interface of menus to reduce overlooked related items. 1. Comparative experiment among a complementary menu using a general-purpose word taxonomy used in a thesaurus and the ones using domain-specific taxonomies based on quick references used in the target document, shows that even novice users prefer domain-specific word taxonomies and exhibit higher performance in retrieval significantly. 2. Comparison between a domain-specific word taxonomy that arranges different categories in a line and another domain-specific word taxonomy which reorganizes the categories under one parent category, suggests users relatively prefer the latter taxonomy but the preference depends on the amount of user's domain specific knowledge. 3. Component menu system which has only one menu showing the whole taxonomic hierarchy with scrollbars on which the positions and relevance of related items are shown is effective to reduce the number of overlooked items.

This paper describes R and D of the ultimate manipulation technology of atoms and molecules (atom technology). Through the observation of super spiral DNA fixed on a spermin or spermidine treated mica substrate by AFM (atomic force microscope), fixation of DNA without any deformation in solution was clarified, and visualization of the spiral structure of DNA were successfully achieved. Manipulation of Xe atoms adsorbed on an Si(111) surface was certainly possible by using STM (scanning tunneling microscope)/atom probe equipment. A nucleation mechanism in crystal growth was studied for various organic source-molecules/GaAs(001) surface systems, and formation of high-density nuclei on the GaAs surface was achieved by accelerating the translational energy of Ga material molecules up to 6eV or more. Ziegler- Natta catalysis important for industrial polymerization of olefin molecules was precisely analyzed by first-principle dynamic simulation. A large-scale simulation of zeolite catalyst is also in promotion for methanol to gasoline conversion. 51 refs., 87 figs., 7 tabs.

Values given to global environment and economy by utilization of photovoltaic power generation are evaluated, and quantified to make clear the significance of the utilization thereof. Specifically, trial calculations were performed on LCA and damaging characteristics of photovoltaic systems, and reducible amount of carbon dioxide emission. Taking up thin film CdTe cells as the object, estimation was made on the energy payback time (EPT) and CO2 emission amount. The production scale ranges over 10 MW/ 30 MW/ 100 MW annually, the useful life is 20 years, and the unit requirement for CO2 emission originated from the charged electric power is 114 g-C/kWh. The EPT was 1.74 in the annual production of 10 MWp, 1.08 in 100 MWp, the unit requirement for CO2 emission was 14.0 in the annual production of 10 MWp, and 8.9 in 100 MWp. This is one of severals of that in the existing power supply source. For heavy metals, particularly Pb, the trial calculation resulted in 0.15 g/Wp in the crystalline type, and 0.1 g/Wp in the amorphous type. The problem therewith is separation and recovery. The reducible amount of carbon dioxide, or in other words, the amount of power that can be generated latently is 37,235 GWh/year, or 3.10 million tons when converted into carbon dioxide. (NEDO)

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)

With an intention to solve environmental problems and energy problems simultaneously in Sumoto City, Hyogo prefecture, surveys have been performed on feasibility of introducing biomass energy in the district. The dairy farming in Sumoto City has a trend of increase in the number of livestocks being fed in individual farms, and increase of milking quantity per livestock (increase of sewage discharge amount), with the increase of excessive excreta amount causing a problem. The Sumoto Dairy Farming Association is experiencing generation of excreta of 156 tons a day, which requires manure handling and disposal of 112 tons a day even after deducting the field dispersion. Discussions on a biogas plant with a capacity of 100 tons a day call for biogas generation amount of 2,500 m{sup 3} a day, electric power generation amount of 4,500 kWh a day, fuel cell size of 100 kW x 2 units, and heat generation amount of 6,000 kWh a day. A total of the estimated project cost amounts to 2,450,000,000 yen, the annual running cost to 65,280,000 yen, and the annual income to 82,000,000 yen. The electric power generation cost is 135 yen per kWh, the heat production cost is 952 yen per liter (converted to kerosene), and the saving amount due to excessive electric power and heat utilization amounted to 10,700,000 yen.

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)

Applicable uses and the market size for photovoltaic (PV) systems were investigated taking into consideration the features and economics of such systems. As a result of computing representative usage examples together with the extent of potential demand for PV, 238 GW for the power source in private homes, 76 GW for green houses, 126 GW for sewage water treatment plants, 4 GW for schools and universities and others were estimated. For the greater number of PV systems already in actual use, non-cost factors acted as major determining factors when deciding on implementation. Promising uses (applicable ideas) seen from the standpoint of non-cost factors were studied in order to develop the PV system market and gain breakthrough for lowering future costs and increasing proliferation for such systems. When it comes to simultaneously decreasing costs and increasing demand for solar batteries in the coming days, it will be impossible to make an immediate transition from the present state of demand for public use and for special use to the final goal of demand as a power source in the home. There is a need for an intermediate demand that can bridge this gap. (13 figs, 9 tabs)

This paper reports the activities of the bituminous coal liquefaction sub-committee in the Sunshine Project in fiscal 1992. With an intention of developing a technology on the process (NEDOL) suitable for liquefaction of wide range of coal types placing sub-bituminous coal at the center, researches were carried out by using a pilot plant, and engineering data purposed for practical application of the technology were acquired. The construction of the pilot plant was launched in fiscal 1991. It is necessary to execute the pilot plant plan steadily in the future, and at the same time, reliably acquire different data by means of supportive researches. Economic performance of the process is also important. The first sub-committee meeting presented the following agenda: the status of constructing the 150-t/d pilot plant, tests and investigations thereon, research works by using a 1-t/d PSU, development of the most suitable coal refining technology, development of a coal pretreatment technology, improvement of the distilled oil distribution, studies on coal liquefaction conditions, and studies on solvent hydrogenating catalysts. The second sub-committee meeting presented the following agenda: the status of constructing the pilot plant, tests and investigations on improving the performance of natural pylite catalyst and circulating solvent, technological investigations on structuring a liquefying reaction data analyzing system, studies using a 1-t/d PSU, development of the most suitable coal refining technology, studies on coal liquefaction conditions, and studies on solvent hydrogenating catalysts.

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

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

Development has been made on element technologies for an esophageal vocalization aid system. With regard to the speaker, selection and trial production were performed on a speaker used for a phono-coupler to be used in coupling with a telephone transmitter. Performance not differing from that in the currently used telephone set was obtained in the overall characteristics evaluation using a dummy telephone circuitry. For the microphone, two kinds of hands-free microphones were fabricated on a trial basis. In order to develop pitch extraction and amplitude pitch conversion systems, pitch extraction performances were compared and discussed on the following five methods: the auto-correlation method, the Cepstram method, the average magnitude difference function (AMDF) method, the simplified inverse filter tracking (SIFT) method, and the time-domain excitation extractor using minimum perturbation operator (TEMPO) method. The hauling phenomenon, having come up as a problem in an auxiliary digital device, was analyzed to discuss methods for prevention thereof. In developing a voice/unvoiced distinction judgment method, a method using low domain power and high domain power was discussed. Development has been made on exclusive ICs, a voice analyzer, and the using feeling enhancing technology. In developing a total system, a digital unit incorporated esophageal vocalization aid system was developed and improved. (NEDO)

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

Surveys and studies were conducted to establish a practical SNG (substitute natural gas) production process. Dealt with in the survey of basic studies on hydrogasification were the effect of gasification conditions, mechanism of tar decomposition, model-using estimation and assessment of reaction heat, and so forth. In an effort to develop a reactor, the current status was studied and future tasks were extracted concerning the one-through type and the internal circulation type entrained bed hydrogasification furnaces. In the study of practical application of the coal hydrogasification process, it was found that gas cooling efficiency would be increased from last fiscal year's 75.2% to approximately 78% by optimizing the process configuration. An ARCH (advanced rapid coal hydrogasification) process to have a novel reactor was proposed, and, for its commercialization, guidelines for dimensionally enlarging the process were worked out and tasks to discharge at each of the development stages were extracted. Relative to pilot tests, an efficient development program was deliberated, in particular, which comprised ARCH-1 and ARCH-2. (NEDO)

Surveys and studies were conducted to establish a practical SNG (substitute natural gas) production process. For the development of an ARCH (advanced rapid coal hydrogasification) process, a plan was prepared covering the basic concept of the process, overall development program, hydrogen/oxygen burner, and an injector. The overall development program comprises element studies (4 years) and the study of the operation of a 50 tons/day pilot plant (8 years), and deals with the development of a reactor and peripheral equipment. Next comes a total system verification effort using a 200 tons/day verification plant in combination with a hydrogen production process, and this aims to achieve commercialization at 3 million Nm{sup 3}/day. As for the hydrogen/oxygen burner, a structure was proposed after surveys of literature and patents on burner structures, ignition methods, and monitoring methods. In the development of an injector, a plan was prepared for testing, and improving, the performance in a cold/hot model of a specimen incorporating the proposed hydrogen/oxygen burner. Basic studies to be carried out include simulation-aided performance prediction. (NEDO)

In 1994 and 1995, a ground-to-ground microwave power transmission (MPT) experiment was carried out by a group of Kyoto University, Kobe University and Kansai Electric Power Company. Among the MPT technologies, which are one of the most important key issues for the realization of the Solar Power Satellite (SPS), studies of `rectenna` (rectifying antenna) have been pursued to archive higher efficiency of conversion from microwave to DC. We had developed a new rectenna panel which can effectively rectify a microwave power of 2.5 W at 2.45 GHz before the ground-to ground MPT field experiment. We examine the sum of the outputs of two or three rectenna panels in which are connected ether in parallel or in series or in the hybrid connection under the same microwave circumstances. The experiment leads us to conclude: (1) The sum of the DC outputs from two rectenna panels connected in parallel is larger than that from those connected in series. (2) The sum of the DC outputs of two rectenna panels is generally smaller than the sum of the DC output of the individual panels unless their output is equal to each other. (3) The total output DC power of a rectenna array increases when we connect the array element with consideration of the `element balance`. Based on the experiment, we propose an optimum method for connection of individual rectenna elements to form an rectenna array. 12 refs., 9 figs., 4 tabs.

The trend of the technology development in the Japanese iron/steel industry was compared with those in foreign countries and surveyed to increase the international competitive strength. From the viewpoints of technology, industry and goods, the iron/steel field was characterized based on the statistic data, and especially automobile use steel materials were selected such as cold rolling high tension steel sheet, surface treated steel sheet, and bearing sheet. The analysis of factors of competitive superiority was conducted, and the following were presented: measures for process continuation, and measures taken from the age of equipment and cost indexes. The paper also surveyed the trend of pig iron making/steel making technology in Asia. The present international technical competitiveness in the iron/steel industry in Japan, especially of automobile use steel sheet, is very high. This is because of the well-functioned demand-oriented development, and also as a result of the mutually influentially conducted equipment development such as process continuation and development of new goods, supposing the iron/steel continuous process and reduction in impurities. However, fears are the stagnation in the recent technical development strength and the saturation of new equipment. Moreover, the further heightening is needed of the international cost competitive strength of general-purpose products. (NEDO)
