    Business corporations modify management techniques in their own way, contriving their own systems of technology and management, and pay heed to outside developments. A quick and flexible response is respected. The two systems of human resources development and assessment are kept open to improvement all the time in the quest for the best practice. Even in professional domains where producer-type employees are wanted for quickly responding to changes, managerial ability to properly meet such changes is considered important. Local administrations in America are engaged in activities that involve the whole population, with their intention explicitly shown of enhancing competitiveness and productivity in their local areas. There are economy-proficient volunteers who function as coordinators in a open way. Measures and policies of administrative agencies and information on them, aiming at creating industries, are provided in an integrated, across-the-board way. Overlapping and functional relationships between personal connections, reputation of the outside parties concerned, systems for assessing invisible things, and voluntary activities of non-government organizations and public service corporations accelerate the good cooperative relations among the industry, the government, and the academia.

    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)

    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.

    With Akinomiya area (11.4 km{sup 2}) selected in Akita prefecture as the survey C area in fiscal 1996, the first survey was conducted. This paper is a summary of memorandum from an advisory standpoint on the evaluation survey concerning the fiscal 1998 investigation results. The contents of the survey are geological investigation, precision gravity exploration, soil gas investigation, electromagnetic exploration, fluid chemical investigation, well drilling and short-term eruption test. An alteration zone was recognized around the place where clay minerals used to be mined, with the center of the zone situated 500-600 m east of a fault. The alteration condition of Akinomiya area seems to be different from that of Doroyu Wasabisawa area. The supplementary gravity survey was carried out at total 58 points in fiscal 1998. It is desirable to set supplementary measuring points over a wide surrounding area for a depth structure analysis. Also performed was a study of mercury concentration in the soil gas. While CSAMT and TDEM methods were employed for the electromagnetic exploration, a suitable method should be carefully selected for a wide area high-density exploration. Consistency with adjacent areas is essential in preparing investigation items particularly for a geothermal model. (NEDO)

    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.

    The general analysis/assessment method of a fossil fuel cycle was studied. Seven kinds of power generation plants such as LNG cycle and coal cycle ones, and four kinds of transport and treatment systems of recovered CO2 such as ocean and underground systems were studied as case studies on life cycle analysis. As data necessary for life cycle analysis, the database was constructed which stores the facilities and operational energy required for a total energy system from mining of fossil fuel to treatment of recovered CO2, and the quantity of environmental waste such as CO2 emission. As a result, the decrease rate of energy balance defined as ratio of input energy to power plant output was estimated to be 14-43% and 20-60% in LNG cycle and coal cycle, respectively. Even if the recovery rate of CO2 in power plants reached 80-90%, reduction of total CO2 emission was limited to only 20-40% because of CO2 emission during mining, liquefaction and transport of fuel. 168 refs., 48 figs., 102 tabs.

    Although the next-generation phosphoric acid fuel cell has nearly reached its practical application stage as far as technology is concerned, its diffusion is yet to come due to lack of data about its cost efficiency and reliability. Under the circumstances, the goal now is to collect and analyze various data obtained in the above-named project which was started in fiscal 1997 for the compilation of data useful for full-scale diffusion in the future so that a foundation may be built for the overall popularization of the fuel cell. In this fiscal year, assessment and analysis have been conducted at 15 test sites now in presence. At the second plant of the Semboku LNG Terminals where approximately 17,000 hours have elapsed since the test began, the cell has operated for more than 16,000 hours in total. The Mycal Bore Sanda has established the longest uninterrupted operation record of 6,500. As for power generation efficiency, a town gas 13A-fueled system exhibits approximately 40% operating smoothly at a high overall efficiency of not less than 90%. (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)

    With relation to some global energy systems of which viability is predicted in the future, an evaluation was conducted from the viewpoints of economical efficiency, energy balance, CO2 emission, etc. The fossil fuel CO2 capture system, the conventional thermal power plant added with CO2 recovery/treatment facilities, is expected to reduce approximately 70-75% of the CO2 emission. The fossil fuel decarbonated hydrogen system, which decarbonates fossil fuels, recovers/treats CO2 at the place of fuel supply and uses as hydrogen, is of poor practical application from an economical point of view. The fossil fuel methanol synthesis system, which synthesizes methanol from fossil fuels at the place of fuel supply, generates electric power and recovers/treats CO2 with the methanol, is large in energy loss and CO2 emission and low in overall efficiency and CO2 reduction effect at the time of methanol synthesis. The renewable energy hydrogen system is an ultimate system with no emission of CO2, though it costs much. 110 refs., 83 figs., 107 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)

    This paper reports the survey results on evaluation of PV power generation in fiscal 1994. (1) On the evaluation technique of energy pay-back time, foreign trial calculation examples by integration method were surveyed. However, there were not many study examples, and the calculation basis of input energy was also ambiguous. The calculation result by input-output analysis in Japan gave the value more than that by integration method, pointing out that indirect input energy is essential. (2) On the evaluation technique of the degree of environmental contribution, CO2 emission of the PV generation system installed on ordinary housing roofs was calculated to estimate reduction of CO2 emission and cost. As a result, PV power generation as reduction measures against CO2 brought a little cost increase. (3) On the latent scale of PV power generation, it was estimated to be nearly 191GW although under no restriction. It was a considerably large value as compared with the current power generation capacity in Japan. 4 tabs.

    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)

    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)

    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)

    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.

    This paper describes the achievements in fiscal 2000 from the WE-NET Phase II for Task-1. Technologies drawing attentions relate to fuel cell driven automobiles and hybrid automobiles in the field of utilizing hydrogen derived from reproducible energies and fossil energies, and fuel cell co-generation and micro gas turbine co-generation in the field of electric power generation. Hydrogen reformed from gasoline on board the automobile as the fuel for fuel cell driven automobiles, hydrogen as a by-product of coke furnace off-gas (COG), and reproducible energy hydrogen have the same fuel consumption performance as in the hybrid automobiles. Particularly the COG is low in cost, and has large supply potential. Liquefied hydrogen is as promising as compressed hydrogen in view of the cost for automotive hydrogen supply stations. What has high economic performance as the self-sustaining systems for islands are photovoltaic and wind power generation, and the system using hydrogen as the secondary energy. Since much of the reproducible energies is used for electric power demand in Japan, the by-product hydrogen and the reformed hydrogen in an amount of 9.3 billion Nm{sup 3}/year would take care of majority of the demand in view of the short time period. For a longer time span, hydrogen originated from the reproduced energies in the Pan-Pacific Region should be introduced. (NEDO)

    With the aim of formulating a strategy for introducing hydrogen, assessment was carried out on the energy consumption, environmental impacts and cost effiectiveness concerning various hydrogen utilization systems. In regard to soda-electrolysis by-product hydrogen and coke-oven by-product hydrogen, hydrogen supply capacity and cost effectiveness were evaluated. As a result, the two systems were found to have an annual hydrogen supply capacity of 11.52 GNm{sup 3} in total. As to the cost effectiveness, transportation by pipeline was 34 yen/Nm{sup 3}-H{sub 2} in the case of soda-electrolysis by-product hydrogen, and 40 yen/Nm{sup 3}-H{sub 2} in the case of coke-oven by-product hydrogen. An estimated cost of power generation showed 56 yen to 67 yen/kWh in such a system on remote islands as replacing diesel power generation by wind power generation, storing part of the electric energy produced in the form of hydrogen through water electrolysis, and using it as fuel for power generation by the fuel cell unit if wind conditions are unfavorable. Power generation cost on remote islands at present is sometimes in excess of 50 yen/kWh; therefore, this combined system showed promising results. The cost of using wooden biomass was estimated to be 51,000 yen/TOE , whose competitiveness is uncertain. (NEDO)

    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.

    A survey was carried out on activities taken in Germany. The industry has a strong opinion to take voluntary regulations rather than those by laws. 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)

    Feasibility study is conducted for introduction of the VICSs (Vehicle Information and Communication Systems) in Malaysia's Klang Valley and Multimedia Super Corridor, to contribute to abatement of the greenhouse effect gases and saving energy. This study has produced the following results. The systems need a total fund of about 1.4 billion yen, including the design fees, when based on the FM multiplex broadcasting, and annual operation/maintenance cost of about 110,000 million yen. These systems are expected to save 4,850 toe/y of fuel and abate CO2 emissions by 11,200 t/y, with the benefit cost ratios of 20.2 toe/million yen and 46.6 tons of CO2/million yen, respectively, when they are in service for 10 years. Introduction of the VICS system in Malaysia is highly feasible both technically and economically, which, however, will need establishment of, e.g., the JICA-proposed integrated traffic information system and Malaysia Traffic Information Authority.

    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. France with take part in COP5, Bonn, Germany, with a general proposal carrying what are stated above. (NEDO)

    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)

    To promote the introduction of methanol fuel into the thermal power plants, total assessment was provided. For calculating the methanol production cost, the plant was assumed to be constructed in the Southeast Asia or Middle East. Two methods, i.e., steam reforming and gaseous phase fluid methods, were investigated. Since the price of natural gas is low in the Middle East, the methanol production cost by the gaseous phase fluid method is estimated to be about 1.5 yen per thousand kcal. The transportation cost can be reduced into one-half to one-third of current cost using a large-scale tanker. Although the heating value of methanol per weight is lower than that of LNG, the volume flow of methanol is similar to that of LNG due to its low specific gravity. Conceptual designs were conducted for some power generation systems, such as gas turbine of combined cycle, diesel engine, and fuel cell. The power generation cost was estimated to be 8 to 9 yen per kWh, which depends on the receiving price of methanol. It is nearly equivalent to that of LNG combined cycle power generation. There are no problems of air pollution and ash disposal. When considering the long-term security of energy sources, the use of methanol would be one of the selections as utilization of natural gas. 6 refs., 33 figs., 25 tabs.

    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)

    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)

    Diesel engines used widely as propelling engines of ships have increasingly been provided with a high output and a high thermal efficiency; their structural members, particularly, the component parts for combustion chambers are therefore used under severe conditions, giving rise to the need of surface treatment and surface reforming of the members. Parts for marine diesel engines are huge, so that the technology applicable to the surface treatment and reforming are limited in point of facility and cost; therefore, most suitable is thermal spraying. This paper primarily discusses, among marine diesel engines, a 2-cycle low-speed engine with a 260-980mm bore used for the main engine of a merchant ship such as a container ship, bulk carrier or a tanker, and a 4-cycle medium-speed engine with a 300-420mm bore used for the main engine of a naval vessel; the paper explains the application status of a thermal spraying technology which is in progress to cope with the high output and high thermal efficiency of the diesel engines, explaining particularly the story of the development and the technological features of the wear resistant thermal spraying, which has been put to practical use, on the cylinder liner and the piston ring of the 4-cycle medium-speed engine.

    This paper considers authorization powers held by the major organizations in the EC, with the Maastricht Treaty kept in mind. One of the objectives of establishing the EC is to harmonize and develop the economic activities in the community on the whole, and promote making closer the relations among the member nations. The EC's supernationality has two aspects: finances (using financial sources from externally common tariffs as the EC's independent financial resources) and legislations (member nations delegating their own powers to the international organization). Organizations involving in the EC legislations are the European Assembly, the board of ministers, and the EC Committee. The Assembly has deciding powers at high levels on the EC budget decision, as well as vetoing power on the budget. The board of ministers is provided with deciding powers to assure achievement of the objectives defined in the official requirements. The Committee has a supernational character that each committee member can act independently free from being subjected to orders from his or her native country. Practically, however, the authorization relationship among the organizations has confrontations over the interests of the organizations and member nations. There have been such movements in this situation as the Luxemburg compromises, actions at the agricultural ministers meeting, and preparation of the unified European protocol. 2 figs., 4 tabs.

    A new concept of multiple stage diesel combustion was studied by means of engine test, combustion observation and numerical simulation, in order to reduce NOx emissions at high load conditions. With this concept, the premixed combustion occurs under the fuel lean conditions and the diffusion combustion occurs under the high temperature conditions. As seen in the result of combustion observation, a first stage combustion occurs with no luminous flame. A second stage combustion occurs with a luminous flame after very short ignition delay period. However the luminous flame is disappeared immediately. Because cylinder temperature is high, and hence soot oxidizes immediately. 5 refs., 11 figs., 1 tab.

    In heat flux measurement in engines, material properties of a heat flux probe and numerical prediction of those influence have been discussed rather than practical measurement accuracy. This study featured the process for the quantitative examination of heat flux probes. Although the process required direct comparison among all the probes and additional measurements in a constant volume bomb, precision of heat flux measurement was greatly improved so that the essential characteristics of heat transfer in engines can be detected. 9 refs., 8 figs., 1 tab.

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

    Premixed lean diesel combustion (PREDIC) makes it possible to achieve low NOx emission. It is an important factor to make the homogeneous spray formation for PREDIC. In this paper presents I the effect of the spray dispersion on emission characteristic were analyzed with the spray observation and engine test. Pintle type nozzle, which has different feature from orifice type nozzle, are used to form the hollow cone spray. As a result, the pintle type nozzle having grooves to generate the swirl flow, makes the reduced penetration in comparison with the hole nozzle under low ambient gas pressure. And it could improve THC, CO emissions at low NOx emission condition. 7 refs., 12 figs., 1 tab.

    A new diesel combustion concept termed MULDIC (MULtiple stage Diesel Combustion), which can reduce NO{sub x} emissions at high load conditions, was studied by means of engine test, combustion observation and numerical simulation. The engine test showed that simultaneous reduction of NO{sub x} and smoke could be obtained with MULDIC operation. In-cylinder combustion observation was carried out in order to clarify the cause of the smoke reduction of the MULDIC. In these photographs, a first stage combustion sins observed with nonluminous flame. In a second stage combustion, a highly sooting luminous flame was observed because the ignition delay was short. However this luminous flame disappeared quickly. Computational results showed that, oxygen is distributed evenly in the cylinder in later portion of the second stage combustion. Moreover, since cylinder temperature was very high, most of the soot oxidized rapidly. Thus, low smoke combustion was obtained. (author)

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

    The thermal loads of the piston top-land surface in D.I. diesel engine during actual operation is not cleared. The authors fixed thin film thermocouples in the top-land center of a standard piston, and measured the instantaneous heat fluxes in that place. As a result, the authors made clear the thermal loads of the piston top-land surface in a cycle, and confirmed presence of the flame inflow to the piston top-land center. In addition, the authors made clear the thermal loads of the piston top-land surface in EGR operation. 4 refs., 8 figs.

    This paper deals with a study on combustion and emission characteristics of a direct injection diesel engine dual-fueled with natural gas. Dual fueling systems tend to emit high unburned fuel especially at low load, resulting in a decreased thermal efficiency. This is because natural gas-air mixtures are too lean for flame to propagate under low load conditions. Intake charge heating and uncooled EGR are very useful to improve emissions and thermal efficiency at low load. Such favorable effects are supported by NO kinetic simulations. 2 refs., 13 figs.

    In order to establish the optimum fueling in a natural gas fueled dual fuel engine, tests were made for some operational parameters and their combination on the engine performances and the exhaust emissions. The results show that the gas oil quantity should be increased and gas oil injection timing should be advanced to suppress unburned hydrocarbon emission at middle and low output range, while the quantity should be reduced and the timing should be retarded to avoid onset of knock at high loads. The unburned hydrocarbon emission and the thermal efficiency are improved at the same load avoiding too lean natural gas premixture by restriction of intake charge air. However the improvement is limited because the ignition and initial combustion of pilot diesel fuel is deteriorated when the cylinder pressure is excessively lowered by throttling. The increase in pilot gas oil amount is effective for low-load operation and the adequate combination of throttle control and equivalence ratio ensures low hydrocarbon emission and the thermal efficiency comparable to diesel operation.

    Fuel sprays and combustion in a direct injection Premixed lean Diesel Combustion (PREDIC) engine, which can make smokeless combustion with little NOx emission, is studied numerically. Numerical simulation was carried out by means of KIVA II based computer code with a combustion submodel. The combustion submodel describes the formation of combustible fuel vapor by turbulent mixing and four-step chemical reaction which includes low temperature oxidation. Comparison between computation and experiment shows qualitatively good agreement in terms of heat release rate and NO emission. Computational results indicate that the combustion is significantly influenced by fuel spray characteristics and injection timing to vary NO emission. 10 refs., 8 figs., 1 tab.

    The cause of unburned hydrocarbon emission in small DI diesel engines at light load was studied. An optically accessible engine which was enabled to visualize the squish area was used to investigate the behavior of spray, mixture distribution and so on. Based on these observations and engine tests, the factors such as the direct impingement of liquid phase fuel spray to the combustion chamber wall the unevenness of fuel spray among holes and spreading of the fuel droplets, mixture and flame to the squish area were supposed to be the cause of forming HC emission. 18 refs., 10 figs., 2 tabs.

    We propose the new fuel injection system by use of diesel fuel dissolved with CO2 to reduce both soot and NOx simultaneously. In this paper spray combustion characteristics of CO2 mixed fuel is reported. It is revealed that flame temperature and KL factor at the CO2 mixed fuel combustion are lower than at the only n-tridecane combustion due to separation or partly flashing of CO2component. And the result of exhaust gas measurement shows the capability that CO2 mixed fuel is able to reduce both soot and NOx simultaneously. 12 refs., 7 figs., 1 tab.

    To clarify soot formation and oxidation process in diesel combustion, the natural emission of OH radical and the flame temperature were obtained in the combustion chamber of D.I. diesel engine. Further, soot were detected by LII (Laser Induced Incandescence) and LIS (Laser Induced Scattering) technique to assess the relative soot diameter and its number density. OH emission and flame temperature were compared with data of soot diameter and number- density. The results show that : (1) OH emission has relation to flame temperature. (2) OH emission arises latter than soot emission, because early soot at early combustion consume OH to oxidate. (3) As soon as it is ignited, soot particles are formed in the region of low temperature. 6 refs., 7 figs., 2 tabs.

The state of artificial internal ears applied to children of high-degree impairment of hearing in the advanced countries is mentioned while pointing out the luck of understanding at deaf schools and their instructors in Japan. Further, an advancement of understanding achieved during the last decade with regard to the cochleae physiology is mentioned including the facts that, tough the utility of hearing aids for those with high-degree impairment of hearing is little as it is merely an amplifier, the auditory hearing of word has been improved by more than 20% with the latest SPEAK vocal processor over older ones, and it is prospected that they may live an every-day life without hindrance by the help of reading on written talk in combination. 12 refs., 9 figs., 1 tab.

    In an attempt to promote the atomization of fuel spray and the mixing of fuel and air in diesel engines, a micro-hole nozzle which has orifices with a diameter smaller than 0.10mm was developed. In this study, the combustion tests were carried out using a single cylinder diesel engine equipped with a micro-hole nozzle and a common rail type high-pressure fuel injection system. A comparison with the results of a conventional nozzle experiment showed that the peak of initial premixed combustion increased, but the peak of diffusion combustion decreased. As a result, when nozzle orifice diameter become small from {phi} 0.15 mm to {phi} 0.10 mm, the combustion was accompanied by smokeless with the same levels of NO{sub x} emission and fuel economy. And results of a comparison the toroidal type chamber with the shallow dish type chamber revealed that the optimization of combustion chamber is necessary for the increase of the injection stage with increasing of the number of nozzle orifice. If an orifice diameter becomes {phi} 0.06 mm, the diffusion combustion can not be observed and the combustion is formed of only premixed combustion. The combustion in the case of {phi} 0.06 mm was accompanied with the drastic deterioration of fuel economy, smoke and HC with all over load. But the micro-hole nozzle has a potential for the formation of the lean and homogeneous premixed mixture until the fuel-air mixture ignites. (author)

    For an aim to reduce NOx emission from diesel engines, it has become possible to realize it with smoke emission maintained at low levels by taking the following steps: initial combustion is carried out as lean pre-mixed combustion by adopting early fuel injection; the fuel is injected again after completion of this combustion; and EGR is combined with two-stage combustion which performs diffusion combustion under high temperature atmosphere. When a large quantity of EGR is used, cylinder temperature drops to have ignition timing delayed in the first stage, serving for improving fuel consumption. The problem of increase in smoke generation is solved by optimizing the injection timing at the second stage to suppress smoke generation increase, resulting in realization of lower NOx emission. By completing the second-stage fuel injection before ignition of the first-stage injection, it was possible to realize further lower NOx emission. Smoke increase due to higher EGR ratio was suppressed by pre-mixing both fuels injected in the first and second stages, although this is a high load operation. In addition, oxygen concentration and cylinder temperature were reduced, the gas pre-mixture was homogenized, and combustion velocity was suppressed by delaying the angle of ignition timing. This made low smoke combustion at {lambda} = 1 possible even in compressed ignition combustion. 8 refs., 12 figs., 1 tab.

    A study is being made on premixed lean diesel combustion (PREDIC) by means of early fuel injection in diesel engines. The PREDIC makes it possible to largely reduce NOx emission, but has such problems as ignition control and increase in THC and CO generation. In order to clarify the relationship between fuel spray characteristics in the PREDIC and properties of gas mixture and exhausts, the present study has investigated spread and internal structure of the spray by means of spray observation experiment using a pintle swirl nozzle. Based on the result therefrom, simulations were used to investigate effects of spatial dispersion characteristics of the spray on properties of the gas mixture and exhausts before ignition. The pintle swirl nozzle forms conical spray having an air layer inside the spray, where penetration is suppressed even under low atmospheric pressure. By forming hollow spray or solid spray in the conical spray, a possibility was indicated that equivalent ratio distribution of the gas mixture can be controlled and NO emission may be reduced. 8 refs., 12 figs., 1 tab.

    NO{sub x} emission was remarkably reduced by PREDIC (PREmixed lean DIesel Combustion) system in which fuel was injected at very early stage of compression stroke and the major part of the fuel is considered to be burned with self-ignition of premixed charge around TDC. However PREDIC system had some problems, a restriction of a high load operation was one of these problems. In order to investigate the combustion characteristics of PREDIC at the richer operation limit, a test engine was operated with gaseous fuel-air mixture where less heterogeneous mixture can be formed than that of conventional diesel engines. A steep pressure rise or the abrupt increase in NO{sub x} emission determined the richer operation limit. This was at 2 to 2.4 of excess air ratio. Supercharging operation enabled the high load operation more than 2.4 of excess air ratio. (author)

    This paper describes new hydraulically-actuated mechanisms for both fuel injection and inlet/exhaust valve operation of diesel engines through solenoid valves, which obviate the conventional cam-driven system. These mechanisms were integrated with an electronic control unit also developed in this study and they were mounted as a mechatronics system'' on a power-increased single-cylinder engine. This mechatronics system was mainly composed of an injection control. boost and accumulation component, an inlet and exhaust valve control component, a solenoid valve, an electronic control equipment, a hydraulic power unit, and a maneuvering unit. The verification test was carried out for the improvement of diesel engine performance by the hydraulically powered mechatronics system. As a result, it was proved not only that these mechanisms provide stable operating characteristics over a wide range of conditions, but also that the electronic control system allows accurate, smooth response. 3 refs., 23 figs., 2 tabs.

    Recently, since higher velocity and higher pressure are required for diesel injection systems, cavitation behaviors in high velocity oil flows are strongly interested in such as 100 to 500 m/s for oil flow velocity and less than the cavitation factor {sigma} of 0.01. In this paper, oil cavitation characteristics at the injection part of multihole nozzles, especially on the flow characteristics, were studied systematically using fuel injection multihole nozzles for an actual use. As a result, it was clarified that subcavitation area (sub C), transition area, and supercavitation area (SC) could be existing in C{sub d}-{sigma} relation, which was similar to that specified cavitation conditions could be exisiting in the actual working area of multihole nozzles. And it was also clarified that flow coefficient C{sub d} relied on Reynolds number R{sub e} in the transition of {sigma}{ge}{sigma}{sub cr} and in {sub C} area, and mainly relied on {sigma} in SC area of {sigma}<{sigma}{sub cr}. Moreover, it was also confirmed that such tendency was similar to the one of the two-dimensional contraction of an area. 22 refs., 10 figs., 1 tab.

    The configuration of water recycling systems with membrane filters was studied to purify waste water discharged from human beings, animals and plants which is a key subsystem for closed ecological life support systems (CELSS) essential to long-term manned space activity. 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.

    PV modules unified with building materials which are low in cost, easy to install and excellent in designing were developed and were evaluated in various tests. As to the basic structure of this module, seamless and unified construction with the back metal plate was adopted considering improvement in fire prevention and cost reduction. About the installation, module is easy to install by just fit connection with the frame, and easy to remove with no use of special tools. Concerning intensity and durability requested for this module, tests on reliability such as torsion strength and wind pressure resistance were conducted according to JIS standards, and it was confirmed that there were no problems. Also on the long-term durability, tests on long-term reliability were carried out by doubling test terms of the temperature/humidity cycle test, salt water resistance test, etc., and the reliability the same as that of the existing type was confirmed. In the verification test using a model house, no changes were seen in electrical characteristics and appearance, and waterproof was also favorable one and a half year after the installation. 4 refs., 7 figs., 5 tabs.

    A geothermal reservoir assessment manual was prepared for the promotion of the development of geothermal power generation, based on the results of the 'geothermal reservoir assessment technique development project' implemented during the fiscal 1984-1992 period and on the results of surveys conducted in Japan and abroad. Of the geothermal systems generally classified into the steam dominant type and the hot water dominant type, encounters with the steam dominant type are but seldom reported. This manual therefore covers the hot water dominant type only. In addition to the explanation of the basic concept and the outline of geothermal reservoirs, the manual carries data necessary for reservoir assessment; geological and geophysical data analyses; geochemistry in reservoir assessment; data of underground logging and of fuming; conceptual models; simulators and models for reservoir simulation; natural-state simulation, history-matching simulation, and reservoir behavior predicting simulation; case history (modeling of a geothermal reservoir prior to exploitation), references, and so forth.

    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.

    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.

    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.

    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.

    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.

    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.

    Concerning a project whose aim is to develop heat resistant engine members through the application of the concept of functionally inclined materials, deliberation and assessment are made of the meaning of its implementation, validity of the research program, research achievement, etc. The project deals with a specimen, diameter 150mm or more and thickness 5mm or more, built of a zirconia/stainless steel-based functionally inclined material, and its goal is to develop technologies for optimizing the baking process for the said specimen, baking system and related devices, assessment technique, tribological assessment technique, etc., and it is inferred that these targets are reasonable. As the result of this research, an energy-efficient (power consumption reduced to 1/3 to 1/5) practical rapid sintering system is constructed. Basic data are collected relative to the tribology of the functionally inclined material, and it is proved that it is feasible to use the material for engine members. The process technology, assessment technology, and devices developed under this project are the first in the world, and are highly evaluated. (NEDO)

    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 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.

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

    The purpose of this project is to clarify the possibility of new hydrogen energy as a future energy source. The new hydrogen energy is obtained from the excess heat generation phenomenon through the electrolysis of heavy water using palladium metal as an electrode. The excess heat measurements were conducted through the excess heat confirmation tests using a fuel cell-type electrolytic cell up to November 1997. As a result, it was found that the excess heat measured by the calibration method can not be measured by the flow calorimetric method. In order to investigate the possibility of systematic errors of the both methods, the sensitivity, accuracy and responsibility, and the conditions of the excess heat generation, research activities based on new facts from scientific information and fundamental research supporting projects have been mainly performed. Among these, were performed the excess heat measurement tests by the cataphoresis method, absorption tests by the high-pressure and high-temperature charging method, gas plasma loading, in-situ X-ray detection, and reactant detection tests using Au/Pd/PdO heterogeneous structural body. 5 refs., 59 figs., 9 tabs.

    In this study, we investigated the relationship of indicated mean effective pressure (IMEP) for a spark ignition engine under lean combustion with the cyclic variation of mass fraction burned by measuring the energy release from the spark plug, intensity of the light emission from the flame and the cylinder pressure at the same time. In order to minimized an error in the initial and late combustion sages of the mass fraction burned to be obtained by cylinder pressure, spark plug energy and intensity of light emission were measured. As a result, it was found that there are three main causes of cyclic variation of IMEP. These consist of the burning speed during the initial stage of combustion, variation in the total mass fraction burned, and variation of the late burning during the late expansion stroke. Thus, we determined that there is a favorable interrelationship between the IMEPs and the corrected mass fraction burned. 13 refs., 9 figs., 1 tab.

In the European countries, with the exception of France, efforts are being exerted to introduce new energy and to enhance its application, renewable energy in particular, in place of atomic power. The expectation they entertain toward new energy is far extensive than that of Japan which retains atomic power generation. Although wind power generation enjoys the overwhelming popularity over others, yet, in Germany and Sweden, it will be difficult for this technology to take the place of atomic power generation completely. As for photovoltaic power generation, not so much is expected from this technology as in Japan because of their climate and weather. 67 figs., 10 tabs.

    This study is concerned with a small bore (93mm) diesel engine using impinged fuel spray, named OSKA system. The higher rate of injection show lower smoke emission with higher NOx Emission. The exhaust emission and performance were investigated under different compression ratio with higher rate of injection. The experimental results show that this OSKA system is capable for reducing the smoke emission without the deterioration of NOx emission and fuel consumption compared with the conventional DI diesel engine. 5 refs., 8 figs., 3 tabs.

    A previous paper showed that EGR cooling and a low compression ratio which prolongs the ignition delay can expand the area of the new combustion concept. Experimental investigations were conducted in this research to examine the effects of the fuel injection rates, the injection pressure and the injection duration, on the exhaust emissions of an engine incorporating the MK concept The results showed that a higher injection pressure was effective in reducing NOx and particulate matter (PM) under MK combustion conditions. 10 refs., 9 figs., 1 tab.

    To reduce the exhaust emissions and fuel consumption of direct-injection diesel engines, it is essential to optimize the fuel injection equipment closely related to combustion and emission characteristics. In this study, three-dimensional computation has been applied to investigate the effects of the injection nozzle specifications (e.g., sac volume, round shape at the inlet of the nozzle hole) and needle tip deviation on internal flow characteristics. The computational results revealed that the effects of the nozzle specifications and needle tip deviation with a smaller needle lift on internal flow characteristics and a general approach to optimize the injection nozzle specifications were obtained. 3 refs., 10 figs., 1 tab.

    By injecting fuel at the very early stage of compression stroke and thus creating homogeneous lean mixture before ignition, (PREDIC ; PREmixed lean DIesel Combustion), simultaneous reduction of NO{sub x} and smoke was obtained. However, since increasing the mixture equivalence ratio cause knocking, it was difficult to operate at higher load conditions. In this study, in order to reduce combustion rate at high load conditions in a premixed compression ignition engine, multiple stage injection method and EGR were combined, and heterogeneous mixture was made before ignition. The engine test results showed that NO{sub x} emissions could be reduced to less than 50 ppm, without knocking even at full load conditions. In addition, smoke emissions were also maintained below invisible level. It can be understood that the premixing of fuel was advanced, smoke was reduced, and EGR rate was increased, resulting lower heat release rate and NO{sub x} emissions. (author)

    The results of the first phase research and development project for developing composite materials as the basic technologies of the next generation are evaluated, and the directions of the R and D evaluation for the second phase are set up. The efforts in the first-phase R and D project are aimed at development of methods for measuring carbon fiber surface structure elements; confirmation of the relationship between adhesive shear strength and active surface area; development of methods for determining fracture toughness by standard specimens; estimation of allowable void fraction for inter-layer shear strength; defect detection and quality evaluation by electromagnetic, ultrasonic, laser holography and AE methods; development of methods for detecting resin setting reactions during the molding processes; and understanding deteriorated mechanical characteristics of the resin-based composites by environmental factors, among others. The objectives of the first-phase project have been almost achieved. It is decided that the second-phase R and D project are directed to investigations on the relationship between surface properties of the fibers in the composites and fiber/matrix adhesion; researches on mechanical characteristics involved in fracture of the structural elements; evaluation of mechanical properties of the metal-based composites and investigations on detecting their defects; elucidation of the effects of environmental factors on their strength; and development of the techniques for integrating detection of molding-induced cracking and that of setting reactivity, among others.

    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 evaluation working group of the Large-scale Energy-saving Technology Research and Development Promotion Council has made an interim evaluation of the results obtained so far by the R and D project for the super heat pump energy accumulation systems. The working group evaluates the bench plant operation test results comprehensively, covering technical, economic and social aspects, and R and D promotion methodology. The working group has concluded that a significant technological break-through is made for the super high performance compression heat pumps, and the technological groundwork is now established for the future pilot system. For the chemical heat storage technologies, it is concluded that system feasibility is demonstrated, and the technological groundwork for the future development is established. The super heat pump is evaluated to potentially realize significant economic superiority over the conventional devices both in the domestic and industrial areas, and to be highly rated potentially in the areas of energy-saving, power load leveling and environmental preservation.

    Among the EDS, H-Coal and SRC-2 lined up in the coal liquefaction project of the U.S., the SRC is aimed at producing 6,000 t/day as a module for a 30,000 t/day commercial plant. They expect Ash contents (iron, sulfur, etc.) in coal without basically using catalysts. The products are applicable to fuels for electricity and gas for the moment. In the element technology, there are some problems in manufacturing hydrogen by gasification of residuals as well as in slurry systems, reaction towers, etc.. In the 30,000 ton commercial plant, the coal-liquefied oil costs $19.89/bbl (price as of 1978) assuming coal costs $29.47; therefore, the feasibility is strong as a substitute for petroleum. Japan's share for the required funds will be 86.8 billion yen (if 250 yen per dollar). Since the kinds of coal are conceivably increased in number through the improvement of the process, the Pacific rim countries and these which lie on the Indian Ocean are assumed to be the major coal producing countries for Japan. The stability in storage of coal-liquefied oil is experimentally excellent, as is the compatibility with petroleum products for example. Great results can be expected in the technical know-how and the spread of element technology for Japan. (NEDO)

The sub-committee, upon having received reports on the result of environmental safety evaluation tests performed in fiscals 1991 and 1992 by NEDO, deliberated and discussed carefully the contents thereof. In order to ensure labor hygiene for coal liquefaction plant workers, health influence on liquefied oil users, and social acceptability of the liquefied oil, NEDO has performed the comprehensive brown coal pilot plant operation and oil safety tests. The tests are in accordance with the labor safety and hygiene law, the chemicals examination law, and the MPD issued by OECD, and performed on each fraction produced in the pilot plant and the whole fraction mixing the former fractions, using rats, rabbits, and guinea pigs. The test items included: acute inhalation toxicity and oral repeated administration (using rats); eye stimulation, repeated coating and skin stimulation (using rabbits); photo-toxicity (using guinea pigs); mutagenicity tests (microorganisms, bacteria and chromosome anomaly); resolution tests; fish toxicity; concentration degrees; algae growth obstruction; and water flea breeding obstruction. As the result, the toxicity was found light. (NEDO)

    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 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.

    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.

    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.

    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.

    The environmental safety evaluation sub-committee has held two meeting in the current fiscal year as described below. The first sub-committee meeting (August 25, 1987) was held for the agenda of the summary of future test plans, the result of overseas surveys in fiscal 1986, the results of tests in fiscal 1986, and the summary of the test plan for fiscal 1987. The major agendum of the second sub-committee meeting (February 23) was the interim reports on the overseas survey results and the safety tests in fiscal 1987. NEDO intends to ensure the labor hygiene for workers in coal liquefying plants, the effect of liquefied oil on users' health, and social acceptability of liquefied oil. Therefore, a safety test for liquefied oil in the primary hydrogenation process was performed provisionally on brown coal PP in the initial stage of operation, in addition to bituminous coal liquefied oil at the existing 1-t/d PDU. The main contents of the test performed by NEDO are based on the labor safety and hygiene law and the law related to regulation on the deliberation and manufacture of chemical materials. Different tests using guinea pigs were carried out on the total fraction mixed at the 1-t/d PDU, and each fraction of light and heavy oils, where the liquefied oil was verified to have minor degree of toxicity.

    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.

    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.

    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.

    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.

    The research and development project for automatic sewing systems is aimed at establishing the techniques necessary for developing (automatic sewing systems) which efficiently produce diversified types of products in small quantities, to cope with various requirements, e.g., diversified consumers' needs and reduced cycle periods. This project covers R and D of the sewing preparation/processing, sewing/assembling, cloth handling, and system management/control techniques. The program for developing the total systems and elementary techniques draws the conceptual designs of their functions, performance and shapes, to outline the overall R and D project. The programs for the individual elementary techniques include studies on their basic functions and performance; design works from the basic designs to determine the specifications to the detailed designs of the devices to be developed; construction of the test units on a trial basis; and function confirming tests to confirm operability of the unit components and device performance, where these works are simultaneously implemented. This paper describes the interim results of evaluation of the elements developed for the elementary techniques, summarizing the results obtained so far. It is concluded that most of the targets of the R and D themes are sufficiently achieved by the end of FY 1987, and that the project can be now advanced to the next phase, construction of the test plants.

    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.

    Change in wettability of coal particle surfaces due to kerosene adsorption was studied by using a film flotation method. The applicability of a film flotation method to coals modified by kerosene adsorption was first confirmed. 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 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.

    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.

    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.

    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 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)

    As for function and quality of information system, an assessment method of productivity at planning and at completion has been developed. 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.

    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.

    Among the EDS, H-Coal and SRC-2 lined up in the coal liquefaction project of the U.S., the SRC is aimed at producing 6,000 t/day as a module for a 30,000 t/day commercial plant. They expect Ash contents (iron, sulfur, etc.) in coal without basically using catalysts. The products are applicable to fuels for electricity and gas for the moment. In the element technology, there are some problems in manufacturing hydrogen by gasification of residuals as well as in slurry systems, reaction towers, etc.. In the 30,000 ton commercial plant, the coal-liquefied oil costs $19.89/bbl (price as of 1978) assuming coal costs $29.47; therefore, the feasibility is strong as a substitute for petroleum. Japan's share for the required funds will be 86.8 billion yen (if 250 yen per dollar). Since the kinds of coal are conceivably increased in number through the improvement of the process, the Pacific rim countries and these which lie on the Indian Ocean are assumed to be the major coal producing countries for Japan. The stability in storage of coal-liquefied oil is experimentally excellent, as is the compatibility with petroleum products for example. Great results can be expected in the technical know-how and the spread of element technology for Japan. (NEDO)

    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.

    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.

    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.

    The paper studies the measures for reduction of environmental load of CO2 from the standpoint of chemical technology. As for methanol synthesis from CO2, accelerating of the reaction using Cu base compound catalyst is reported. Also, CO2 is methanated at high speed by low temperature waste heat using Ni-La2O3-Ru catalyst. Discussions are given on the subject for development of catalyst reaction relating to hydrogen production technology by methane reforming reaction using steam or CO2. Synthesis of polymetric materials by use of CO2 is also described. The paper mentions that it is indispensable to design high-function electrode and elucidate the reaction mechanism of electrochemical CO2 reduction for electrochemical and photochemical CO2 reduction measures. Moreover, in case of using solar energy, it is required to study photovoltaic excitation process in semiconductor electrode/ electrolyte solution interface. For production of hydrogen from CO2 by photosynthetic organisms and solar energy, the problem is control of inhibiting effect of oxygen combinedly produced. Described are production of polyhydroxy butyric acid and biodegradable polymer from CO2 and hydrogen by bacteria, and CO2 fixation imitating the enzyme reaction. 267 refs., 79 figs., 32 tabs.

    Surveys were conducted of the effect on waste quality of the Law for Promotion of Sorted Collection and Recycling of Containers and Packaging, diffusion of PFI (private finance initiative) involving refuse-fueled power generation, recycling of slag, etc. Questionnairing was conducted for the survey of the effect on waste of the effectuation of the recycling law, size of population supplying the waste and the amount actually incinerated, actually measured data of the composition of incinerated waste, assorted collection programs, amount reducing measures, and the like. Studies were made as to if the empirical formulas applied in the survey of the preceding fiscal year would remain applicable after the coming into force of the recycling law. In the survey of PFI popularization, it was found that the rate it was taken into account for concrete projects was so low as 13.8% though most of the autonomous bodies had cognizance of PFI. It was requested that it be clearly stipulated that 'the conventional subsidies and grants apply also to PFI projects.' In the survey of conversion of residue into molten slag in refuse-fueled power generation and its reuse, four kinds of slag specimens were examined for physical properties, elution, and analyzed for ingredients, and then it was found that they posed no problems like heavy metal elution.

    In order to extract promising areas with high geothermal feasibility, the Akinomiya area was surveyed by drilling test wells. In the N9-AY-3 excavating work, the first stage (depth from 15 to 33 m) used the water-free excavation to prevent adverse effects on the water sources. The second stage (depth from 33 to 409 m) reached the targeted depth with slanted excavation. The third stage drilled into depths from 409 to 1,006 m. The fourth stage was targeted to drill down to 1,802 m, but an entire lost returns have occurred at the depth of 1,598 m, whereas lost water drilling was performed by using fresh water, and the drilling was terminated at the targeted depth. The AY-4 excavation was also advanced with the first, second, third and fourth stage method, and when the entire lost returns have occurred at 1,196 m, the lost water drilling was carried out by using fresh water, and the drilling was terminated at the scheduled 1,505 m. The AY-5 excavation was also advanced with the first, second, third and fourth stage method. The first and second stages used water-free excavation (using air hammers) to avoid influence on the nearby spa areas. The third stage went down to 405 m performing coring, but the entire lost returns occurred at 298 m. The excavation rate was very high, and the core recovery rate reached 100%. The fourth stage presented the same coring condition as that for the third stage down to 1,002 m. (NEDO)

    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)

    The test on jetting of geothermal water by the induced jetting, sampling of geothermal water and analysis/survey were carried out in the structure drilling well of N4-HG-2 in the Hongu area, Wakayama Prefecture. The induced jetting of the well was conducted by the Swabbing method up to the total pumping amount of 459.9m{sup 3} that is equal to about 24 times as much as the inner quantity of the well, but it did not result in jetting. The maximum temperature of geothermal water was 65.6 degrees C, pH was 6.6-7.5, electric conductivity was 2,800-2,900 {mu}S/cm, and Cl concentration was 500-700ppm. The geothermal water was classified into the HCO{sub 3} type that is neutral, and the spring quality and liquidity were the same as those of existing hot springs in this area. In the Hongu area, the distribution of new volcanic rocks has not known. The K-Ar age of quartz porphyry intrusive rocks was made about 13Ma, and it was considered that a possibility was low of the rocks being heat sources of geothermal activities. It was also considered that the geothermal water/hot spring water in this area, which originate in the surface water, were heated in heat transfer by magma activities in the deep underground and were flowing forming a small scale of hydrothermal convection system.

    The survey purpose is to identify availability of coal resources for liquefaction in major coal producing countries in the Pacific basin area. Therefore, collection is carried out on such data as coal existing conditions, coal qualities, production quantities, and infrastructures on coal mines being operated and projects under development or investigation. Coal samples are collected in wide range and exhaustively unbiased to particular coal fields and mines to acquire data to perform selection and evaluation of coals that can be fed to coal liquefying plants. The present survey was intended to acquire fundamental data for the liquefying coal selection, such as coal existing conditions, natures, and infrastructures for the coal resources, taking up as the survey object countries the State of Alaska, U.S.A. and Indonesia. The coal types as the object of the survey are mainly sub-bituminous coal, and additionally brown coal and partly bituminous coal. The amount of coal deposit as the subject of the investigation is 100 million tons or more as the verified reserve. The subject areas cover coal mines in the State of Alaska, U.S.A. (Northern Alaska, Nenana, Beluga, and Matanuska coal fields), and Indonesia (the Sumatra and Kalimantan islands). The survey items are made up of 14 items (see the coal mine survey tables in JN0040851). (NEDO)

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

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

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

    The purpose of the present study is to elucidate coal quality features of different types of coals and identify the relationship between the coal quality features and the liquefaction characteristics by performing liquefaction characteristic evaluation tests. Based on the result therefrom, a method is established for coal field assessment that can estimate yield of liquefaction in coal fields and coal mines to serve for selection of coal types suitable for liquefaction. Coal quality feature surveys and liquefaction characteristics evaluation tests under the standard conditions have been completed on 48 coal types including Canadian, Australian and American coals. Elucidating the coal quality features of different coals can specify parameters for the coal quality features related to the liquefaction characteristics. Coal ranks elucidate the vitrinite reflectance, structure constituent factors the vitrinite content, composite factors the volatile matter content, quantity of heat generation, and number of H/C and O/C atoms. Investigating the relationship between the coal quality features and the liquefaction characteristics can provide fundamental data for primary screening of raw material coals for liquefaction. The result of the liquefaction characteristics evaluation test under the standard conditions can be the detailed comparative data relative to data derived from the simplified liquefaction characteristics test that is performed to estimate liquefaction yield of specific coal field and coal mine.

    This paper explains groundwater investigating methods, introducing particularly two methods. The resistivity tomography is a method to measure potential distribution generated when current is applied around an area to be investigated. Using the measurement result as projection data, the resistivity distribution is restructured within the area of the investigation. The paper summarizes the measurement method (measuring equipment, electrode arrangement, etc.), the analytic method (establishment of an initial model, and the alpha-center method to calculate theoretical potentials corresponding to the model), and an application example of the method in which the resistivity change was observed using permeation of salt tracers. The resistivity imaging method (two-dimensional resistivity analysis method) is superior in practicability to the above method under the present state of the art. This method does not differ from the conventional resistivity method in methodology, but improves the analytic accuracy over the conventional electrical investigation method as a result of analysis combining the simplified two-dimensional analysis method with the alpha-center method. A summary is given on the measuring and analyzing methods. 13 refs., 10 figs.

    The pressurized coal partial combustion (PCPC) furnace is surveyed/studied for its incorporation in MHD generation. The technical development of the atmospheric CPC has been basically completed, and the concept is demonstrated using a test system of commercial size. Many techniques developed for the atmospheric CPC are applicable to the PCPC system. These include structures of the CPC furnace walls, and slag handling and simulation techniques. Combination of PFBC with PCPC or IGCC can bring about many merits, e.g., enhanced efficiency and abated NOx emissions for the combined cycle power generation. These topping cycles, therefore, should be developed in the early stage. MHD power generation is one of the concepts that can enhance efficiency. In particular, the techniques for closed cycle MHD generation have notably advanced recently. The PCPC techniques are useful for coal combustors for MHD generation. Full-scale development works for the direct coal combustion gas turbine systems have been just started for the IGCC systems of the next generation, and the PCPC-related techniques are expected to serve as the central techniques for these turbine systems.

    Of the FY 1998 survey for preservation of Jozankei Hot Spring, a survey was conducted with the aim of grasping the state of variation in ingredients of hot spring, etc. in the area and of elucidating the causes of hot spring variation. During the period from October 27, 1998 to August 28, 1999, the following were carried out: sampling of specimens of spring water at 6 spring sources, river water at 2 points and precipitation at 2 points; measurement of temperature, spring temperature, pH, electric conductivity, etc.; analyses of Na, Ca, CL, HCO{sub 3}, SiO{sub 2}, etc. The results of the analysis are as follows. As to spring sources, A-2, A-7 and B-1, the precipitation or river water flow rate seem to largely affect the variation in hot spring measuring values. As to spring resources, A-6 and B-4, the relation with the precipitation or river water flow rate is not clear, but a big change is recognized in the snow-melting season. The tendency to the two variations seems to be caused by the difference between the spring with which the river water is greatly concerned by the crack system of the spring having reached the river and the spring which was closed on the earth surface. The temperature variation of springs was considered to be affected by the river water which flowed into the springs. (NEDO)

    An environmentally friendly refuse energy utilizing business, for which RDF (refuse derived fuel) produced out of wastes discharged by industries belonging to a Fujieda city environmental protection council will provide the heat source, is proposed by the said council. The proposal is subjected to a study, a basic plan is drafted, and a decision is made on its profitability. In the study, surveys are conducted on the actualities of wastes and of demand for heat, and specifications are worked out relating to transportation and storage of RDF, production of steam by an RDF-fired boiler, routing of pipes for transmitting the steam to the industries in the district, facility costs, operating costs, etc. It is found that the amount of RDF produced out of the wastes discharged by the council member industries is so small that it can meet the demand of only one industry and that, even if more wastes are collected from a wider area, the increased amount will but meet the demand of two industries and a hot water pool. It is found that the system will be economically feasible, however, if the shortage of RDF-generated energy is covered by an oil-fired boiler and thereby impartiality is established in steam distribution and steam production unit price is reduced. In view of the intensification of control over dioxin, etc., the business will be gaining profit in 2002 and after. (NEDO)

    This survey studied the feasibility of large-scale offshore wind power generation in Japan. Attempt was also made on preparation of outline maps of offshore wind around Japan. The cost of future offshore wind power generation systems is roughly dependent on technical issues and environmental issues. As technical issues, 'installation site,' 'foundation,' 'system interconnection' and 'maintenance/management' were summarized based on applications in Europe. As a result, it was clarified that technical issues can be solved with existing technologies to a certain extent, however, those relate to economical problems closely. The previous environment impact assessments say that wind power generation has no problems on the environmental issues. As relatively strong wind coastal areas, the outline maps of offshore wind point out Western Hokkaido area, Japan Sea area of Tohoku district, Pacific ocean area of the central part of Honshu, Genkai Nada area, Western Kyushu area and Southwest islands area, and suggest that these areas are promising for offshore wind power generation.

    Field survey was made on the current state of and issues on energy in Vietnam. In Vietnam, firewood is in wide use as non-commercial energy, and sums to a half of total energy consumption. Other energies such as hydroelectric power, petroleum, natural gas and coal are self-sustainable. Commercial energy consumption in 1995 is estimated at 10,070,000t in oil equivalent, which is broken down into 23% for coal, 42% in oil, 5% for natural gas and 30% for electricity. Abundant water resources will form the mainstay of future electric power supply. Commercial production of oil started in 1986 becoming an oil exporting country. Several promising natural gas fields were discovered as the result of the exploration by foreign capital. Coal deposits are estimated to be nearly 3.5 billion tons, and most of them are anthracite. Electric power demand is growing at a higher rate than the economic growth of Vietnam. The growth rate of electric power demand is set to be 1.3 times that of GDP. Since construction funds for new plants cannot be satisfied with the national budget and domestic investment alone, the country is expecting foreign capitals. 21 figs., 36 tabs.

In the Jozankei area, with the Usubetu layer in the Old Tertiary system as the basement, layers are superposed from the Palaeogene Oligocene to the Quaternary Pleistocene. Distributing in various places between Yunosawa vicinity and Jozankei Hot Spring area are acid to neutral geothermal alteration zones. The hot spring gushing-out zone in the Jozankei hot spring area is supposed to be regulated by side-by-side cracks in the NE-SW direction. It was inferred from tritium concentration and a minor component ratio that, as the mechanism of forming a hot spring, water of precipitation origin circulating and residing for a long time on the Usubetsu layer which is marine sediment is heated by a volcanic heat source latent in the depth.

    This survey studied the feasibility of large-scale offshore wind power generation in Japan. Attempt was also made on preparation of outline maps of offshore wind around Japan. The cost of future offshore wind power generation systems is roughly dependent on technical issues and environmental issues. As technical issues, 'installation site,' 'foundation,' 'system interconnection' and 'maintenance/management' were summarized based on applications in Europe. As a result, it was clarified that technical issues can be solved with existing technologies to a certain extent, however, those relate to economical problems closely. The previous environment impact assessments say that wind power generation has no problems on the environmental issues. As relatively strong wind coastal areas, the outline maps of offshore wind point out Western Hokkaido area, Japan Sea area of Tohoku district, Pacific ocean area of the central part of Honshu, Genkai Nada area, Western Kyushu area and Southwest islands area, and suggest that these areas are promising for offshore wind power generation.

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

    Geothermal resources have been evaluated in the Copahue district. For this survey administrated by JICA, drilling of a deep test well with a small bore (COP-3) and blowout tests were conducted. This district is located at the east side of the Andes elongated in the N-S direction. Volcanoes with similar active periods and active states are distributed in the N-S direction, which forms a divide with the Pacific Ocean side. The Copahue-Caviahue composite volcano in the surveyed area is located nearly in the central part of the volcanic zone, which forms a special ring topography. Geology of the Copahue district consists of volcanic effusive rocks during the Tertiary and Quaternary periods. There are five prospecting fields with geothermal indications in the surveyed area. From the survey, an area of about 13 km{sup 2} was evaluated as a geothermal resource field. Especially, in the area of about 4 km{sup 2} including COP-1, 2 and 3 wells, the steam predominant type reservoirs were found out. As a result of estimation of the geothermal resource potential by the volumetric method, a highly prospective power generation potential of 30 MW was evaluated in the field where the steam predominant type reservoirs were confirmed by the boring wells. 7 refs., 13 figs., 1 tab.

    A report is made about the result of vertical electric sounding conducted in the MK district, Fukuoka City, where Kyushu University is about to move. As for the method of electrical prospecting, in consideration of the need for probing a depth of 50m at the shallowest, vertical electrical sounding with a Schlumberger array of electrodes was employed. Measurements were made for 57 locations on the planar ground, the interval between electrodes gradually increased from 1 to 200m. In the 2D structure model analysis, a 2D inversion program was utilized in the ABIC minimization method. Also investigated were the relationship of electric prospecting and the geology, geological conditions, water level in the well, water quality, salt water, and pore rate from the previously-conducted investigative boring. As the result, it was estimated that the boundary between the first and second layers detected by electric prospecting reflected the level of underground water and that the boundary between the second and third layers reflected the portion where the N-value sharply increases. 4 refs., 8 figs.

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

    A survey was made on autonomous responsive materials as a new material which reversibly change molecular structures and the aggregation state according to external stimuli. Autonomous responsive materials imitate environmental responsibility in the living organism system and have sensing, control and active functions for external stimuli. The materials are highly efficient and environmentally friendly. In biomimetic materials for soft actuators, drastic changes by temperature of elastic modulus of water-swollen hydrogel are used to the motion. In order to molecularly design stimulus-responsible polymer gel, studied are the relation between the micro structure and stimulus responsibility, dynamic correlation between the micro structure and the macro structure, etc. In the biomedical field, new cure and diagnosis using innovative materials are expected, and the application of autonomous responsive materials to the field is studied. For example, using hydrogel responding the temperature and the surface and controlling by temperature the interaction with components of the organism such as protein and cells, drug delivery in the organism is optimized. Also studied is the application of hydrophilic/hydrophobic changes by temperature to the chromatography. 215 refs., 47 figs., 11 tabs.

    Electromagnetic surveying method is applied in Muroran Institute of Technology`s site for power transmission steel towers for the locating of structures buried in the ground and for the study of obstruction to the application of the method. The devices employed are the EM31 and EM38 which are portable conductivity measuring instruments manufactured by GEONICS Company. With the probeable depth in the horizontal dipole mode being approximately half that in the vertical dipole mode, depths of 0.5m, 1m, 3m, and 6m may be explored using the two instruments. In the measurement test, the devices are used to determine a reinforced concrete-made multi-purpose duct that accommodates water pipes, sewers, various electric wires, and heating pipes and is buried at a depth of 2-3m in the ground. In the measurement for a 3m-deep level, a spot high in conductivity due to the reinforced concrete is detected, and the result roughly corresponds to the lay of the duct. In the measurement for a 6m-deep level, no high-conductivity spot is found, meaning there is no such structure at this depth. Although there are some other high conductivity values recorded, they are attributed to manhole covers or steel tower bases on the ground surface. 3 refs., 8 figs.

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

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

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

Rapid increase in the emission of greenhouse-effect gases, especially CO2, is predicted in China with remarkable economic growth and population of 1.2 billion. It is essential to promote the Joint Implementation activities in China. In this survey, framework, organization, problems and tasks were investigated to effectively promote the Joint Implementation activities in China. Construction of framework for the real Joint Implementation activities has been proposed. Current problems for promoting the Joint Implementation activities in China are that the distinct guideline for the Joint Implementation is not established in the government, that the receiving system including receiving, planning and arranging sections is not established, and that the burden problems for the costs of project evaluation, data acquisition, monitoring, and verification are not solved. 5 refs., 21 figs., 6 tabs.

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

    Comparisons were made of the power generation cost in Indonesia and Thailand between the photovoltaic power system and other power systems. From the difference in technical standards with Japan, trially calculated were the amount of the potential introduction and the possibly reduced cost. In Indonesia, a plan has started for the introduction of a 50W system to 1 million houses in the unelecrified area, but the introduction has not been so promoted as planned. In Thailand, a plan is being carried out for the introduction of the battery charge station system, but the introduction has remained small-scaled. Comparisons were made among the solar home system in Indonesia, the battery charge station system in Thailand, the diesel engine power generation, and the grid connection with the existing power distribution system. The result concluded that the solar home system is low-priced though it depends on the distance from the existing distribution line and the power consumption amount. Moreover, it was found that the system would be more economical than in the case of Japan if obeying international standards for the photovoltaic power system. 6 refs., 15 figs., 56 tabs.

    This paper describes the survey of energy load leveling systems in Europe. In Denmark, especially regional heating is remarkably diffused, and they have 350 plants. With extending the service areas, the energy load leveling has been promoted. For the cogeneration plants of SK Power, the largest electric power company, they have hot water heat storage tanks for regional heat supply with a total capacity 2,200 MWh. The regional heating system in Goeteborg City of Sweden supplies 80% of the total heat demand of the city. Unused energy sources derived from petroleum refining, sewage treatment, and garbage burning are utilized. In Uppsala, they have seasonal heat storage systems using solar heat. The Vienna Regional Heat Supply Corporation supplies heat equivalent to 5,000 GWh a year. Cogeneration plants and garbage burning plants are used as heat sources, and 25% of the total heating in the city is supplied. In Austria, they have an electric power demand with a peak in winter, and they have a pumped-storage power station in Kaprun for the annual load leveling using dump power in summer. This paper also introduces a compressed air storage gas turbine plant at Huntorf of Germany, and a large-scale underground natural gas storage of Gaz de France. 6 figs.

    As a part of the survey of selecting promising drilling points, survey was made using soil gas to grasp the area of existence of geothermal fluid in the area for careful examination and the locational distribution of fractures controlling the behavior of fluid. In the survey, the concentration of Hg in soil gas/carbon isotopic ratio of CO2 were measured at 247 measuring points. Generally speaking, there existed the hydrothermal fluid along the structure controlling geothermal activities in the area where the concentration of Hg in soil gas is high, and the volcanic gas as a heating source of geothermal fluid was rising in the area where the carbon isotopic ratio is high. In the survey, areas where both the Hg concentration and the carbon isotopic ratio were high were extracted as promising areas where the high temperature geothermal fluid possibly exists. The promising areas extracted were the periphery of the Daiichi (No.1) Shirotori Hot Spring, periphery of KT-4, southern periphery of N4-ST-2, periphery of 54E-OBN-1 - 54E-OBN-2, and periphery of N4-ST-2. Besides, a possibility of existence of geothermal fluid was indicated in the northeast of N4-ST-1 and in the northeast of KT-9. (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.

    For analytical evaluation of effects of environmental protection measures, energy conservation measures, new energy promotion measures, etc., a very-long term energy supply/demand model was developed and used for a simulational study. The model is composed of the models of macro economics, secondary energy prices, new energy introduction, and energy supply/demand. The feature is that the amount of new energy introduction is measuringly analyzed based on the cost and market scale, and integratedly estimated in a frame of energy supply/demand of the whole Japan. As a result of the simulation, energy source as of 2030 is composed of coal (17%), oil (44%) and nuclear power (15%) in the case of the economic growth as viewed optimistically. Contrarily, in the case of it as viewed pesimistically, energy source is composed of coal (11%), oil (40%) and nuclear power (22%). CO2 emission is -12.4% in the case of the new energy promotion than in the standard case. 7 refs., 79 figs., 107 tabs.

    In order to utilize energy reasonably over the whole life cycle of products, the life cycle assessment (LCA) was researched including assessment of the quantity of environmental load. LCA is composed of the inventory analysis which analyzes objectively the amount of input and output of all substances and energy due to their gathering, mining, transport, production, use, recycling and scrapping, and the impact analysis to environment based on the inventory analysis. The inventory analysis of refrigerators was conducted. The unit amount of CO2 emission generated by production of materials was estimated on the basis of previous papers. In particular, CO2 emission due to overseas production of imported raw metals reached nearly 80% in Al and 70% in copper. Recycling of materials and heat recovery by combustion of waste were also considered. Environmental effect was next assessed using the inventory data in three stages of classification, characterization and valuation. Although the weight factor of environmental effect is necessary for every emission, European and American data are now used. 59 refs., 68 figs., 81 tabs.

    Forests have become drawing attention as an absorption source of carbon dioxide, a greenhouse effect gas. This paper discusses significance of forests from viewpoints of their roles as diverse ecological systems and socio-economic values. Forest is a place for living and resting of all kinds of living organisms including plants, animals and microorganisms. Living forms in forests being affluent in kinds and large in amount bring great favor to human societies. Forests play diversified roles other than biological roles in addition to largely affecting heat distribution on the ground through evapotranspiration. These roles include suppression of erosion on ground surface, alleviation of micro climate by reducing wind velocity on the ground, and disaster prevention. Forests have an aspect of supply source of production resources for societies as well as an aspect of unused lands. Efficiency of converting solar energy by plants looks inferior to that of solar cells. Biomass may be regarded as regenerative energy limited to a case where excess production is utilized. 142 refs., 56 figs., 44 tabs.

    Harmonized molecular materials (HMM) were researched to create functional materials adaptable to needs such as environmental harmony and high-efficient conversion in post-industrial society and aging society. Superior mechanisms function efficiently in organisms for perception, transmission and processing of information, and transport and conversion of substances. These functions are caused by harmonization between organic molecules, or organic molecule and metal or inorganic substance. HMM is a key substance to realize these functions similar to those of organisms artificially. It is the purpose of this research to develop HMMs, reform production process by innovating separation and conversion technologies, and finally realize molecular chemical plants. This research also develops high-efficient devices to contribute to the information society, and progresses the industry of bio-functional materials such as high-sensitive bio-sensor. The functions, applications and creation technologies of three kinds of HMM such as assembly, mesophase and microporous materials were researched in fiscal 1995. 956 refs., 128 figs., 13 tabs.

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

    A coal type research project is started under which data concerning the coal resources that Japan can make use of are to be gathered, which are necessary for determining their fitness-for-use in a coal liquefaction or gasification process, and the gathered data are to be compiled into files which are easy to use. As for the buildup of a computer-aided data bank, since the number of coal types is not yet large, only part of the data is taken into consideration this fiscal year. In the study of compiling the data into files, it is decided that the files be divided into two categories, one for grasping the status of the development project as a whole and the other for defining the positions of the individual coal specimens. Provided in the former are outlines covering the name of coal mine or project, location, entrepreneur, states of the mining area and geology, state of production, infrastructure-related matters, etc. Described in the latter are the details that enable the identification of given specimens such as the coal bed or coal brand, location and method of collection, collector, date, amount of the specimen, method of treatment, etc. (NEDO)

    As functional material to satisfy various needs for environmental harmonization and efficient conversion for information-oriented and aging societies, HMM were surveyed. Living bodies effectively carry out transmission/processing of information, and transport/conversion of substances, and these functions are based on harmonization between organic molecules, and between those and metal or inorganic ones. HMM is a key substance to artificially realize these bio-related functions. Its R & D aims at (1) Making a breakthrough in production process based on innovation of material separation/conversion technology, (2) Contribution to an information-oriented society by high-efficiency devices, and (3) Growth of a functional bio-material industry. HMM is classified into three categories: (1) Assembly materials such as organic ultra-thin films (LB film, self-organizing film), and organic/inorganic hybrid materials for optoelectronics, sensors and devices, (2) Mesophase materials such as functional separation membrane and photo-conductive material, and (3) Microporous materials such as synthetic catalyst using guest/host materials. 571 refs., 88 figs., 21 tabs.

    Computer chemistry was investigationally studied. The advance of theoretical chemistry is indispensable to the design of materials, and the theory and high speed computational method are expected which can simulate the real system with more accuracy. It is basic to simulate structures and physical properties of structural molecules and the aggregate, but the meso region, the intermedium region between structural molecules and the aggregate, has became regarded as important. Rough visualization models in high polymer materials and the progress of computational software/hardware of quantum chemistry/molecular dynamics such as catalyst become necessary. Seamless zooming is proposed as a concept of the software which simulates materials from micro/macro/meso viewpoints. Moreover, to make the most of computer chemistry, an integrated system is necessary which generally handles computational software, database, etc. For the development of software, indispensable is the demonstrative verification by a combination of experiments and researchers. Under a commission from NEDO, the investigational research was conducted as a leading study during fiscal 1996 and 1997 to view the course of the research. 17 refs., 37 figs., 5 tabs.

    Disaster caused by liquefaction is an important problem for the development of water-front because most of the places suffered from liquefaction disasters recently are located on sandy grounds. The damaged cases in the past due to liquefaction induced by earthquakes are grouped into: subsidence and inclination caused by the loss of supporting force of the ground, coming to the surface of buried structures due to excess pore hydrostatic pressure, destruction of lifeline accompanying the fluidization of ground, breakdown of bulkhead, retaining wall, etc. by increased earth pressure, sinking of soil structures, ground fissure, sliding, and immersion in floods and submergence of farms due to spouting of underground water. As regards prediction of liquefaction, description is made on the prediction of the occurrence of liquefaction and liquefaction prediction for which sedimentation environment is taken into consideration. Open-cut investigation can be said as the most effective means for accurate learning of the depth, thickness and sedimentation structure of liquefied layers. Liquefaction layers found in remains are also introduced. 16 refs., 6 figs.

    In this paper, recent investigations and researches on pollinosis are summarized as centering on the investigation entrusted by the Ministry of Health and Welfare and executed since 1992, and especially the surveys on Japanese cedar pollinosis during 1995 to 1996. The quantity of pollen surveyed in 1995 is the greatest in the survey history of nationwide flying pollen. Particularly, the quantity of cedar and hinoki pollen is 10 to 40 times as many as that in the year before. Consequently, since the sensitization and onset due to the cedar pollen increased greatly, the objects of the surveys and the researches were mainly in respect to the analysis of onset factors of pollinosis, clarification of its natural process, evaluation on the effectiveness of desensitization therapy, the clinical subjects including the confirmation of pharynx symptom and asthma symptom, and the discovery of naturally sensitizing dog. A fact that the quantity of flying pollen concerns the occurrence and degree of the clinical symptom has already been indicated by a clinical observation carried out for a long period of time. In respect to specific prophylaxis and therapy, for the first time the pollen masks and glasses sold on the market are investigated, and the necessity of the verification thereof is described. 27 refs., 7 figs., 5 tabs.

    The paper conducted the modeling on the economic/industrial structure giving the economic frame for energy supply/demand forecast, and made some simulations. In the simulation, assumed were a standard case, aging/hollowing case, and technical innovation case. As to macroeconomic models, macro items such as the economic growth rate, prices and IS balance were determined by giving foreign factors, financial factors, population factors, etc. In long-term energy supply/demand models, data on demand by use in commercial/residential and transportation sectors were estimated using various statistics. About the calculation result of a standard case of the former sector, the existing industries which markedly ebbed are primary products, the material system, construction/civil engineering, etc. Contrarily, the production industry such as general machines, electrical machines and automobiles increased the share. New and highly growing industries are new production industries like electronics and communication and new services like finance, insurance and communication.

    This report describes the construction of `Green Recycling System` which aims to change deserts to lush lands and to stabilize food supply. A cross-linked polymer produced by irradiating the gooey threads of natto (fermented soybeans) with gamma rays can absorb and hold up to 5,000 times its own weight of water. This biodegradable polymer may be used to develop seed gels and pellets to grow soybean, rice and wheat to improve the productivity of deserts and to protect threatened lands from desertification. This technology will be of great value in establishing stable supply of food resources, especially for the Middle East where deserts are expanding as well as for Africa where serious food shortage is already in place. To undertake the Green Recycling System Project, it is indispensable to develop technologies for producing PGA polymer in large quantity, mass production process of bridged PGA through radiation, chemical cross-linkers, new technologies for growing plants using water retainers, water-retaining materials for arid areas, general systems for growing plants in arid areas, and environmentally benign industrial infrastructures. 76 refs., 59 figs., 29 tabs.

    For assessment of the possibility of the wind farm (collective wind power facility) in Japan, site conditions, business plans and various issues in development were arranged using some projects in a planning stage. The case study of a system design was also conducted for a typical site. Four sites were selected based on geographical conditions, topographic features and weather conditions. Scales of every site are as large as 1000-3000kW and 400- 750kW in wind turbine capacity. Every developer expects a subsidy, and governmental economic support is indispensable for the wind farm. In the case of Hisai city, Mie prefecture with the most favorable wind condition in Japan, the annual mean wind velocity of the site is valued at nearly 8m/s, suggesting that it is promising for the wind farm. From the planned scale of 750kWtimes4, the annual generated power and availability factor are valued at 9,800,000kWh/y and 37%, respectively. From the construction cost of 1 billion yen including a subsidy of its half, the generation cost is valued at 14.5 yen/kWh in durability of 15 years, and 12.2 yen/kWh in 20 years, and the profitability is dependent on the purchase price of a power company. 27 figs., 36 tabs.

    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)

    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)

    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.

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.

    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.

    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.

    This paper reports a method to detect reflected wave components contained in an elastic wave caused in association with well drilling. Measurement was made on an elastic wave caused in association with well drilling in an experimental field by using a triaxial elastic wave detector disposed in a measurement well. Analyzing the particle motion tracks in the derived elastic wave signals (to derive the main axial direction of a three-dimensional hologram) revealed that oscillation direction of the signals changes non-steadily by time centering around the S-wave oscillation direction. In addition, a sound source position was estimated during the drilling. Existence probability of the S-wave signal in the non-steady continuous signals was estimated by handling the particle motion tracks stochastically. In addition, this existence probability was used as a weighting function for a correlative analysis to detect a reflected wave from directly reaching wave components in the non-steady continuous signals. Thus, improvement in reliability of reflected wave detection was attempted. Effectiveness of this method was endorsed by the field data. 3 refs., 7 figs.

    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)

    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.

    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.

    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.

    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, 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).

    Importance of the human behavior technology was paid attention to to get true safety and comfortableness of life through adaptability of products/systems to all humans. In consideration of the social and technological background, the human behavior recognition evaluation technology avoids economic/social losses caused by accidents and troubles and also provides the safe life environment for living people including the aged. Further, the gist of the project was proposed to make it clear that it can give a course of making things from a viewpoint of development of products dealing with individuals (personal fit) and can give new added values and contribute to heightening of international competitiveness at the same time. Development is made of technology of dividing concrete behavior patterns into types and also accumulating them in usable forms at the time of product design and in emergency and of technology of measuring all the time information on human behaviors in daily life without restrictions and on site. Supporting technology is developed for making the most of behavior information of users for product design and in emergency. Effects of the spread are also estimated. 76 refs., 13 figs., 9 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.

    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.

    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.

    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.

    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)

    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.

    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.

    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

    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.

    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.

    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.

    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)

    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 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.

    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.

    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.

    This research and development project is aimed at treatment of sewage, industrial waste water and the like at lower cost for reutilization, while efficiently producing methane or the like by the systems annexed to the water treatment systems with high-concentration bio-reactor systems incorporating separation membranes. The waste water types studied to be treated by these systems include sewage discharged in large quantities and waste water containing oil/fat and protein (low-concentration waste water), and starch-, alcohol and paper/pulp-containing waste water, and excrements (medium-concentration waste water). The project has found the optimum systems, by adequately configuring the separation membrane modules, and combining dissolution of suspended solid with methane fermentation reactors for selective treatment of organic substances; improved efficiencies of removing organic substances and producing methane by fermentation, and realized reduction in quantities of discharged sludge; and thereby established the bases for the new waste water treatment techniques. The reactor systems developed for water treatment are those based on biological removal of nitrogen. They greatly reduce treatment time to produce treated water of high quality. For treatment of sludge, the techniques have been developed to convert sludge into oil. These results are well applicable to various areas, e.g., sewage treatment, and food and pulp industries.

    An inventory data collecting format is formulated, data collecting activities are launched through 23 industry associations and several investigatory agencies, and almost all the primary data are collected. All the inventory items are being rearranged into a convenient order, and efforts are under way to designate the association to be in charge and the method to be used for data collecting (the accumulation method, process model method). Problems about techniques in the veinous department are extracted. The flow of matters relating to various metals and glass after their use and the magnitude of their environmental impacts at the ultimate sites of treatment are understood though roughly. Investigations are conducted into typical formats overseas, a data arranging format is constructed, specifications are defined for a data inputting software program, and a request is placed with a dedicated dealer for the compilation of the said program. The architecture and specifications of an LCA (life cycle assessment) database system are determined, and its functions are undergoing an intermediate check by a research team for improvement. Endeavors are exerted at quantifying global warming, ozone layer depletion, biotoxicity, and photochemical oxidants for use as the basic data for damage evaluation. (NEDO)

    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.

    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.

    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.

    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.

    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.

    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).

    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.

    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)

    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)

    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.

    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.

    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.

The project aims to establish technologies required for putting to practical use a high-speed computation system capable of speedily dealing with huge technological problems which the computers available at the commencement of the project failed to solve. The goals set for new devices and comprehensive systems were sufficiently challenging in view of the technological level of those days, and are still at the highest level in the world. It is judged that the goals were set with reason and appropriateness. The liaison council for the implementation of the project is constituted of people of experience or academic standing, entrusted research and development activities, Ministry of International Trade and Industry bureaus concerned, and the Electrotechnical Laboratory of the same ministry. Discussion, coordination, and communication on concrete matters are under way between the constituent members, contributing to the enhancement of research and development.

    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.

    Under the assumption of a large-capacity DC power transmission model project in the Far East and Siberia districts, technical study was made on the basic design of the project, considering selection of concrete power generation and consumption sites and power transmission routes, power transmission/transformation equipment, cables, and environmental impact. Study was also made on its applicability to similar projects in Japan. The model project aims at integration of Eastern Integrated Power System in the Far East and Russian Unified Power System, and development of abundant undeveloped hydraulic and tidal power generation in the Far East. The study result showed that (1) construction of the high-voltage DC power transmission (HVDC) system of model project class voltage and capacity in Eastern Siberia is possible technically enough, (2) the total construction cost of the model project scheduled to be put into operation in 2025 amounts to nearly $4.7 billion, and (3) the model project is environment-friendly without any CO{sub 2} gas emission because of hydraulic and tidal power generation.

    Single fuel operation with diesel fuel has been tried experimentally for the Homogeneous Charge Diesel Combustion method (HCDC). The higher the pre-mixed fuel ratio, the lower the emissions. But diesel knock due to early self ignition may be occurred under high pre-mixed fuel ratio conditions and consequently the maximum pre-mixed fuel ratio is restricted by these knock limits. Full load operations with higher pre-mixed fuel ratio can be possible with a supercharging which improve the knock limits and emissions. 8 refs., 12 figs.

    This paper reports an image processing analysis of combustion for a high-pressure direct injection diesel engine on the effects of air swirl and injection pressure upon combustion in the diesel engine. The paper summarizes a method to derive gas flow and turbulence strengths, and turbulent flow mixing velocity. The method derives these parameters by detecting movement of brightness unevenness on two flame photographs through utilizing the mutual correlative coefficients of image concentrations. Five types of combustion systems having different injection pressures, injection devices, and swirl ratios were used for the experiment. The result may be summarized as follows: variation in the average value of the turbulent flow mixing velocities due to difference in the swirl ratio is small in the initial phase of diffusion combustion; the difference is smaller in the case of high swirl ratio than in the case of low swirl ratio after the latter stage of the injection; the average value is larger with the higher the injection pressure during the initial stage of the combustion; after termination of the injection, the value is larger in the low pressure injection; and these trends agree with the trend in the time-based change in heat generation rates measured simultaneously. 6 refs., 14 figs., 2 tabs.

    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)

    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.

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 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.

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.

    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.

    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.

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

    For the purpose of clarifying the environmental impact to result from the digging of borehole N11-MD-3 in Shibetsu-gun, Hokkaido, a survey was conducted of changes in (1) hot spring water quality, (2) noise/vibration pollution, and (3) air pollution due to hydrogen sulfide, before and after the digging period. Under item (1), measurements were made at four hot springs, which involved weather, air temperature, water temperature, amount of welled-up water, pH, electric conductivity, etc. Although minor changes were observed during the measuring period, none was found related to the digging process. Under item (2), noise levels were measured during the drilling period along the site boundary, at a point 500m from N11-MD-3, the Kawakita hot spring, and the entrance of Sekiyunosawa. Along the site boundary, they were 55-60 dB during the drilling period, and there was an increase of 30dB attributable to the drilling. At the 500m point, there was a 15-20dB increase attributable to the same. Vibration levels during the drilling period were 40dB along the site boundary and less than the observable minimum at the other points. Under item (3), at four points along the site boundary (50m), hydrogen sulfide concentration in the air fluctuated by 0.01-0.21ppm when the steam discharge rate was 4.47-7.20t/h. (NEDO)

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

    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)

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

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

    For the establishment of a practical process for substitute natural gas (SNG) production, technological and economical assessments were made, and tasks to discharge for the development were discussed. In this fiscal year, the results of surveys conducted in the past five-year period were compiled, and studies were made to prepare for a smooth transition to the element research stage. Findings obtained are described below. SNG producing technologies need to be developed, with the demand for SNG increasing sharply, to further stabilize the base for SNG supply; coal which is abundantly available should be used as the material for SNG; and coal hydrogasification, among various methods for producing SNG from coal, is the most suitable in view of efficiency and cost performance. It was also found after a prolonged study for the improvement of efficiency and cost performance that probabilities were high that the yield of BTX (benzene, toluene, xylene) would increase and cost performance would improve. Besides, a basic plan and an element technology research plan were prepared for the development of the ARCH (advanced rapid coal hydrogasification) process. (NEDO)

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

    In order to ensure international applicability of engineer education such as in universities and other organizations, and to improve the environment to supply human resources demanded by economic societies, surveys were performed on the external accreditation system for engineer education such as in universities and other organizations. In the field of electronic information communications, a committee to correspond to JABEE was established to perform system build-up, where the discussions were advanced. This field was classified into the following four specified areas: general aspect of electric/electronic/information communication engineering, electronics, information communications, and information systems. A supplementary explanation was given on the educational contents except for the information systems, based on which the self-assessment criteria and the evaluation table (for trial use) were prepared. For the examiner training, instructors were invited from ABET in the U.S.A., and training meetings were held. In addition, two committee members were sent as observers to the examinations being carried out at ABET. The trial experiments were conducted for the information communications program at the engineering department of Niigata University, and the electronic system engineering class at Sendai Radio Wave Industrial College. This paper summarizes the results of the examinations. (NEDO)

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

    To elucidate chemical components of soil gas in the Okushiri Island area, soil gas was collected by the method using charcoal adsorbent, and analysis was made by the GC/MS method. Out of the 19 measuring points, 17 points were set up near the measuring points in the FY 1998 survey by the finger print method. At the same measuring points, analytical survey by the MS method was also conducted to sort the type of soil gas. As a result of the GC/MS analysis, xylene or ethyl benzene was detected at 12 measuring points of all 19 measuring points, and from the distribution, it was predicted that there were anomaly zones in the district along the road of the Okushiri Island line and the district southward from the 5.8K Pass. These results were in harmony with the results of the survey by the finger print method. As to the sorting of soil gas based on the results of the MS analysis, the results were different at 8 measuring points from those of the survey by the finger print method in FY 1998. It was considered that the cause was the accidental vaporization of a large quantity of acetaldehyde, and acetaldehyde was regarded as a noise gas component that does not reflect the geothermal structure.

    This investigation was intended to clarify the possibility of existence of geothermal reservoir layer by elucidating the underground structure and thermal source forming the geothermal system around Musadake, in the area extending over Nakashibetu-cho and Shibetu-cho, Shibetu district, Hokkaido, and further by grasping the distribution and properties of the geothermal alteration zone. The geothermal system of the subject area seems to be governed by Musadake - Mt. Shitabanupuri fault, its incidental bent zone, and the graben extending to the southeast side. The thermal source is presumably a magma reservoir that evolved Musa volcano. The depth hot water is presumed to exist in the underground depth around Mt. Imora; and it seems that the thermal conduction and volcanic ejecta are caused by a chain of volcano-related magma reservoirs around Musadake, the thermal source presumably. The depth hot water is estimated to be not less than 250 degrees C and a high Cl concentration. Within the graben, mudstones are distributed such as Kawakita layer and Yokoushigawa geological layer. Moreover, it is possible that an impermeable layer due to alteration is spread. (NEDO)

    With an objective to set up a system for full-scale lifetime education, a feasibility study has been performed on preparing new educational materials and performing seminars. The continuing education program developed by the Japan Society of Mechanical Engineers is intended to assist engineers studied under the new engineer system to accumulate actual work experience after having acquired the qualification, and motivate ability maintenance and self-enlightenment after having acquired the engineer qualification, mainly through the training meetings and lecture meetings held by the Japan Society of Mechanical Engineers. The education items in the major field course include dynamics of materials and machines, energy and flow, information and control, and design and production. The items in the general common course include presentation and communication, kinetics learned from actual cases, engineer ethics, product liability and product safety. The seminar was held for two days for engineers graduated from undergraduate departments and experienced in actual works for two years or longer as the object. The actual status survey related to the continuing education by corporations revealed that 83% of the corporations has implemented intra-corporation training, and encouraged positive participation to outside seminars.

    This survey was conducted to estimate effects of drilling of geothermal exploration well on the environment, aiming at grasping the present state of environmental elements before the survey/development. As a result of the literature survey, the following distribution were confirmed in the fauna: 5 orders 10 families 19 species in the mammalia, 10 orders 25 families 73 species in the aves, 1 order 3 families 6 species in the reptilia, 2 orders 6 families 9 species in the amphibia, and 17 orders 179 families 719 species in the insecta. In the flora, a distribution of 132 families 670 species was confirmed. The results of studying the above indicated that in the fauna, there were 10 species such as antelope as valuable animal in the area surveyed and that it is necessary to pay much attention to the environmental preservation of the habitat for those animals in the well drilling associated with geothermal survey. In the flora, the 13 valuable animals selected as animal having a fear of extinction in the 'plant-version red list' were confirmed in the area surveyed and the periphery. Further, as to the plant colony, there are no important colonies in terms of preservation. In well drilling, important things are efforts exerted to restore to the original state of the area altered, prevention of the washed-away of mud water, etc., and efforts exerted to preserve the environment of vegetation.

    The purpose of this research is to clarify the application condition and effectiveness of high-temperature CO2 fixation and utilization technology. To evaluate the present process, it was compared with others, such as separation using a polymer membrane, physico-chemical absorption process, adsorption process, hydrogen contact reduction process, and biological fixation. The development trends of absorption, membrane, adsorption, and cryogenic separation were investigated. The questionnaire was carried out about the separation technologies which are in the stage of performance test using actual gas, to arrange and compare the data and information. The current trends of chemical and biological CO2 fixation and utilization technology were also investigated for arranging the subjects. High-temperature CO2 disposal by the carbonation in concrete waste has been studied, to clarify its application conditions and effectiveness. In order to compare the separation technologies, treatment processes of CO2 in the exhaust gas from boilers of LNG power generation and coal fired power generation were simulated. These processes were simulated by ASPEN PLUS for the modeling. Trends of application of ASPEN PLUS and collection of information were surveyed by participating in the ASPEN WORLD. 103 refs., 51 figs., 55 tabs.

    Japan proposed in the Houston Summit the New Earth 21 to be carried out with technology development and technology transfer, and to make a concrete development of the project, Japan also proposed in the Tokyo Summit a TREE Plan for working out comprehensive strategies of the innovative technology development. In the CO3 Kyoto Conference in 1997, numerical targets for developed countries were determined which have legal binding force for control/reduction of greenhouse gas emissions in the term of 2008-2012. It was agreed to urge developing countries also to play a certain part in the project through the clean development. Therefore, the paper made quantitative analysis of important CO2 prevention technologies, technology transfer costs, and economical assessment by energy conservation. As a model, the DNE 21 model was upgraded and used into which CO2 prevention technologies, energy, economy and climate changes were integrated. In fiscal 1997, the following were carried out: collection of data on important CO2 prevention technologies and systems and analytical assessment using the DNE 21 model, CO2 reduction and selection of energy technology, assessment of energy system costs, construction of the unified DNE 21 model, and opening of the international workshop. 62 refs., 98 figs., 34 tabs.

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

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

    Test boring at 21 places and core sampling were conducted during September-November 1998 along the ridge to the west of Hay Gulch and in the direction crossing the northwest of the drainage canal and National King Coal Mine (NKC coal mine). It was found that A layer which NKC coal mine is now drilling is the upper part of A coal seam where the seam bifurcates. The boundary to the west of the thick A coal seam is not clear, and there is a possibility that more reserve from the thick coal seam and single seam exists toward Cherry Creek. In the existing coal drilling area, the lower A seam existing under the upper A seam becomes thin rapidly, and the seam thickness becomes less than 1 foot. The average thickness of thick coal seams is 9.9 feet, and the area is 780 acres along the ridge. The upper A coal seam except the above is 5.5 feet in average seam thickness and 910 acres in area. The reserve is 23 million tons. As to the quality of thick coal seam, the average heating value is 7,089 kcal/kg, sulfur content 0.68%, and ash content 7.50%. As coal drilling conditions, the same level as or higher than those of NKC coal mine is expected. (NEDO)

    For the purpose of reducing the risk to accompany the exploitation of deep-seated geothermal resources, investigations are conducted into the three factors that govern the formation of geothermal resources at deep levels, that is, the supply of heat from heat sources, the supply of geothermal fluids, and the development of fracture systems contributing to the constitution of reservoir structures. In fiscal 1996, the deep-seated exploration well WD-1a is sidetracked for penetration for a target newly assigned at the 3,000m-deep level. Carried out in a survey of well geology are the naked-eye and microscopic observation of core cuttings, X-ray powder method, examination of inclusions in fluids, chemical analysis of whole rocks, analysis of isotopes in minerals, analysis of core fracturing, etc. Also, data are collected from a survey of mud log, survey of water in the well before digging, and from well logging. Furthermore, pressure monitoring etc. are conducted in order to determine the interference in pressure between the deep-seated and shallow-seated wells that accompanies multiple outbursts from the Kakkonda No. 2 machine, to know the water permeability between the shallow-seated and deep-seated parts, and to grasp the anisotropy in permeability in shallow-seated reservoirs.

    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)

    In the COP3 Conference on Global Warming held in Kyoto in December 1997, the framework on greenhouse gases was agreed in discussions comprehensively made among Japan, the U.S. and the E.U. As a result, it is for 6 gases including CO2 and methane, and total emissions in developed countries are to be reduced 5% at least during 2008-2012 from the 1990 level. Target of each country is determined by gaps, and Japan`s reduction target is 6%. Therefore, to pass the numerical target agreed, it is necessary to take measures such as rationalization of the energy use by energy saving, etc. in the country and also measures such as promotion of the greenhouse gas emission control in developing countries. Accordingly, for the future development of NEDO`s AIJ project, a possibility of cooperation in the joint implementation was surveyed such as the state of greenhouse gas emissions of countries which are objects of GAP in Southeast Asian countries and neighboring countries, policies of the countries after the COP3 agreement, technological transfer for the emission control, etc. Countries for survey are Thailand, Indonesia, the Philippines, Malaysia, Vietnam and Myanmar. 21 figs., 15 tabs.

    Focusing on the present status and future of coal demand in Central/South American countries and the coal trade between Central/South American countries and the U.S., the paper described the present status and future of coal demand there and the effects on Japan. Export of Colombian coal will amount to approximately 30-35 million tons in 2000. Venezuelan coal 10-20 million tons. The U.S. imported good-quality general coal low in sulfur content, 3.08 tons from Columbia and 1.39 tons from Venezuela. Coal export from the U.S. to Central/South America was mostly of raw material coal, 5 million tons in 1993 and 5.39 million tons in 1994. General coal was 180,000 tons. The U.S. has no plans of increasing US coal export to Central/South America. But it is safely predicted that Columbia and Venezuela will increase coal export to Europe in the future. It will bring about decrease in export of US coal to Europe, which connects with increasing pressure for the coal trade amount of Japan. 21 figs., 47 tabs.

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

    As to intelligent transport systems (ITS), the paper views the outline of the R and D and diffusion in Europe, the U.S. and Japan and trially estimated the effect of reduction in greenhouse gas, and worked out visions/scenario for diffusion of ITS. As developmental fields contributing to reduction in greenhouse gas, the following were taken up: 1) AVCS (advanced vehicle control system), 2) automatic rates receiving system, 3) traffic management, 4) plans of operation management/allocation of commercial cars, 5) modal shift of the material flow, and 6) public traffic in passenger transportation. As effects by developmental field, 1) and 5) are especially effective. 4) is promising because of its easiness in introduction, and 2) is also a promising technology as a tool to introduce an electronic road pricing system on general roads in future in addition to the effect of reducing heavy traffic by its introduction to expressways. However, the higher the service level on the facility side becomes, the more the traffic demand amount becomes. By how to introduce ITS, it possibly occurs that improvement of the situation will not be made at all on the future vehicle traffic system. 38 refs., 42 figs., 52 tabs.

    For geothermal development in the Musadake region, Shibetsu-gun, Hokkaido, structural boring was carried out and boreholes were inspected. In the structural boring survey, borehole N11-MD-3 was drilled as deep as 2,001.18 m, and borehole N11-MD-4 2001.44 m. Performed or tested for each of the two boreholes were temperature logging, electrical logging, temperature recovery, reinjection, core cutting examination, and so forth. The result of the temperature logging shows that temperature rise is slower at levels deeper than 1280 m in borehole N11-MD-3, with the maximum temperature marking 274 degrees C, and, in borehole N11-MD-4, the maximum temperature is 198 degrees C. No reinjection test is carried out because the ground pressure is too high to allow the replacement of the borehole content with fresh water. Analysis results lead to a conclusion that the hot fluid in this region originates in fossil seawater and in meteoric water, the latter arriving after a long-term permeation process, heated by thermal conduction to 270 degrees C or higher. It is inferred that the geothermal fluid flows in a fissure in the vicinity of the Musadake/Mt. Shitabanupuri fault and a fault orthogonally crossing the said fault for the formation of a high-temperature geothermal storage. (NEDO)

    Researches were conducted aiming at the establishment of an ozone-aided highly efficient decomposition process for the persistent organic matters in municipal sewage and industrial wastewater. Tested for verification were advanced water treatment technologies of the biological function acceleration type and the effect of their combination with the accelerated oxidation method, conditions necessary for efficient operation, and water treatment apparatuses and systems for operating them at high efficiency. Some findings are stated below. With an ozone-aided process performed at the first stage of biological treatment, biological decomposition is accelerated for a rise in the persistent organic matter decomposition rate. This is nothing but a finding in the laboratory, however, and much remains to be disclosed concerning the optimum conditions, reforming of sludge to be generated, volume reduction of the same, etc. Another finding involves the acceleration of decomposition of persistent organic matters using ozone in combination with hydrogen peroxide, ultraviolet radiation, titanium oxide, and the like. There still remain numerous tasks to carry out, however, which relate to the investigation of the reaction mechanism, establishment of operating conditions and criteria for selecting oxidants, etc. As for ozone, remaining to be solved are the problems of generation cost, storage and preservation, and safety.

    The trend of technology is surveyed from a standpoint that, in the process of CO2 fixation using microbes for the production of useful substances, it is essential, in view of income/outgo balance and economy, to utilize their catalytic function. The survey centers about the feasibility of the utilization of organic wastes, cellulose wastes in particular, as an energy source. Special attention is paid to the energy of artificial light and laser beams. From a point of view that it is important to suppress cell multiplication and to effectively utilize only catalytic activity for the production of useful substances, the cell division mechanism of the Corynebacterium is analyzed, and the findings are compiled to facilitate the study as to whether the division may be controlled. A report is also prepared on the metabolic mechanism of a photosynthesizing bacterium that is judged to be the most promising species. Reference is made to aerobic and anaerobic bacteria. Shown are the organic compounds that are formed by CO2 gas fixation thanks to microbial or enzymatic reactions. To emphasize their importance as an energy source and to explain the conversion of biomass into useful substances, the technology and economy of conversion into fuel compounds are surveyed. The production of ethanol out of organic wastes is evaluated in the way of LCA (life cycle assessment). (NEDO)

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

    The feasibility study is conducted for introduction of the district energy-saving measures in City of Aizu Wakamatsu, for which the actual situations of energy consumption and promising energy-saving measures are surveyed. The city has a typical basinal weather, cold in winter and very hot and humid in summer, and tends to have a longer air-condition period in a year. It is considered that there are many wasteful energy consumption items to be studied for reduction. In the area of moving means, dependence on public transportation systems is considered to be relatively low, suggesting that there are much space of reducing transportation energy by the measures such as self-imposed control on use of private cars, promotion of utilizing public transportation systems and fuel-saving type driving throughout the city. The promising energy-saving measures studied to verify the effects include introduction of PVM analyzers for establishing better cost/effect relationship between power consumed by air-conditioners and pleasantness; introduction of garbage power generation, co-generation and high-efficiency illuminators; improvement of power-factor; and demand control for air conditioning, rationalization of power-receiving facilities, introduction of systems for saving flushing water and improvement of air conditioners' outdoor facilities.

    Phase 1 survey in fiscal 1996 was conducted based on `Agreement on the comprehensive survey of a coal transportation system in South Sumatra` concluded between NEDO and the Ministry of Mine and Energy in Indonesia. In the survey, conducted were collection of data on coal fields and site surveys, collection of data on inland transportation and site surveys, collection of data on harbors and site surveys, and worked out were a simplified database and a coal transportation plan by optimization of the coal chain system. The area for survey is the periphery of the Musi River of South Sumatra. The results of the simulation by LP models were as follows: When the coal of Bukit Asam coal mine is $25/t in price, only coal of 5500Kcal/kg is profitable, and when $27/t in price, coal of 4500Kcal/kg also becomes profitable. This shows that if the coal is of good quality, it can pay arriving at Suralaya, independent of the distance of transportation. 47 figs., 63 tabs.

    The energy-saving and other global environmental technologies are surveyed by collecting relevant information from various institutes, both abroad and domestic, to contribute to development of ceramic gas turbines. USA has announced a climate change plan, based on the five principles, to promote utilization of high-efficiency technologies and development of new clean technologies. UK is promoting to improve energy efficiency, along with liberalization of its energy markets. Germany concentrates its efforts in the 'Program for Energy Research and Energy Technologies.' France places emphasis on prevention of air pollution and rational use of energy. The R and D trends at public institutes, e.g., universities, for global environmental technologies are surveyed, from which a total of 14 themes are extracted as the seed technologies. At the same time, a total of 9 techniques potentially applicable to the seeds are extracted by mainly reviewing JICST and patent information, and assessed. The R&D trends of the IPCC-related researchers are also surveyed, but provide no theme directly applicable to the seeds. Most of the related themes at the private and public institutes surveyed, both domestic and abroad, are concentrated on carbon dioxide. (NEDO)

    The pilot phase of the activities implemented jointly (AIJ) was approved in 1995 in the 1st Conference of the Parties (COPI) of the United Nations Framework Convention on Climate Change to reduce greenhouse gas emission. In order to promote the AIJ Japan program smoothly, some practical examples in every preceding country and the situations and demands of Asian countries were researched. It was confirmed that since larger cost-effectiveness is achieved just in countries lower in emission control cost, AIJ can enhance the cost-effectiveness and promote environmental technology transfer. Japanese government had studied establishment of the framework for AIJ, and decided the basic framework of the AIJ Japan program in 1995. The government also approved the evaluation guidelines of this program which include confirmed and considered matters necessary for government offices related to this program to evaluate and approve each project.

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

    In order to ensure international applicability of engineer education such as in universities and other organizations, and to improve the environment to supply human resources demanded by economic societies, surveys and discussions were performed on the external accreditation system for engineer education such as in universities and other organizations. In the survey on the information field, a trial was attempted on the information related course at Kyoto University and Osaka University based on the accreditation criteria discussed with an objective of establishing the external accreditation system. The trial was performed on computer science for Kyoto University and software engineering for Osaka University. The activity has provided the examiner side with an opportunity to actually experience the accreditation work, and the examiners had a feeling that the work can help improve the education. The side receiving the accreditation indicated problems in the present system including the concern about the system becoming a mere shell. In addition, participation in the accreditation examiner training work for the information field in the U.S.A. has provided useful information such as thoroughgoing observation of the duty of confidentiality.

    The paper conducted the demonstration of the multiplier effect of 'the model project for heightening of the international energy consumption efficiency, etc.' carried out by NEDO and its subsidiary project, 'the project on the basic survey for promotion of Joint Implementation (JI),' and the comparative study between these projects and the JI/CDM projects proposed in the world. In the quantitative evaluation of the multiplier effect, in the case of making the demonstration of the same technology in the same area both in the model project and the basic survey for promotion of JI, it becomes possible to grasp the CO2 reduction effect with high accuracy, but the CO2 reducible amount is small. Inversely, as to the technology for which the basic survey for promotion of JI is studied, but the model project is not carried out, it becomes possible to grasp the CO2 reduction effect with low accuracy, the CO2 reducible amount is large. In the comparison with the JI/CDM projects proposed in the world, the CO2 reduction amount was approximately $2.7 billion, 250 million tons, in the UNFCCC project, and approximately $5.0 billion, 500 million tons, in the IJ project. There was no very big difference in the cost effect. (NEDO)

    For the purpose of promoting the utilization of clean energy vehicles (CEV), survey was made on the assessment of the pollution by the CEVs introduced by now, subjects on the utilization, etc. As to the transport business use CEV running in the market, CNG vehicle is mostly used, and therefore, the gas emitted from them was tested. As a result, it was found out that CNG vehicle emits fewer NOx, PM and soot/smoke than diesel cars and contributes to improving the air pollution in large cities. However, it emits more CO2 than diesel car, and accordingly, it is necessary to reduce the fuel consumption. The practicality in the limited running distance is almost the same as that of diesel car, but it is desirable to improve startability, acceleration and gradability. Further, the occurrence of any troubles was pointed out in a third of the total numbers of CEV vehicle. Improvement in reliability is a must. CEV is higher in car cost than diesel car, and for the spread/promotion, it is necessary to prepare for assistance such as subsidy. Moreover, there are many requests for improvement in number, business hours, supply capacity, etc. of fuel supply station. (NEDO)

    An investigation was conducted with the aim of elucidating the foundations for effective utilization of environmental pollutants or unused resources which are likely to be causal substances of environmental pollutants, as resources, using biotechnology. Composting of agricultural waste, production of microbial mycelium proteins and microbial fermentation materials were suggested as main examples of effective utilization of unused resources by microorganisms. Selection of active microorganisms in the livestock waste, clarification of the mechanism of action and the establishment of treatment conditions are essential to new developments in this field. In the field of marine products industry, it was pointed out that the recycling of waste using microorganisms and enzyme treatment is the most promising approach to the effective utilization of resources. In the field of food industry, applications as the culture media for mushrooms, for enzyme production and for the production of physiologically active materials as well as fuel were clarified. Was also pointed out the significance of studies on the microorganisms and enzymes in resources containing cellulose, hemicellulose and lignin, and the waste from these resources, lignocellulose. Were also proposed the composting of household waste, methane fermentation, and fermentative production of organic acid and hydrogen from waste. Possibility and significance of fermentative production of organic acid from sewage sludge were suggested. 314 refs., 46 figs., 33 tabs.

    For the establishment of a CO2 measures introduction scenario which the world would accept, the latest information was collected, the DNE21 (Dynamic New Earth 21) model was improved, and simulation was reviewed. In fiscal 1998, simulation was performed for each district using an LDNE21 (Linear Dynamic New Earth 21) model, and an energy flow chart, energy balance table, and trade table were prepared and subjected to detailed deliberation. Studied were also conducted about the changes to occur in methanol production when the natural gas reserves and plant cost data were given different values. In the DNE21 model, the 'macro economy model' and 'warming damage function' were integrated, and simulation was performed for verification. Using a standard model compatible with COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change), comparison was made between a case in which different CO2 emission constraints were imposed on the advanced area and developing area separately and a case in which one and the same constraint was imposed on the world as a whole, and calculations were made about CDM (Clean Development Mechanism).

    This report surveys potential impacts of ASEAN (Association of South East Asian Nations) on inter-ASEAN affairs and its external relations when ASEAN will enlarge its members to include all nations in South East Asia, and thus fully represent the region. For this purpose, the survey was conducted on Vietnam, Myanmar, Laos and Cambodia, which joined in 1995, from the viewpoint of their economic and political system, and their relations with other member countries. The nature of ASEAN has gradually transformed, in which all the countries in the region have increased and internal economic issues have been tackled. It has an aim to stimulate inter-ASEAN trade and induce foreign direct investment into ASEAN as a whole by reducing import duties on intra-ASEAN trade. Underlying in these, new development is a concern about growing economic and military power of China. ASEAN solidarity will work an leverage against China should change toward worse, and ASEAN will function as a regional stabilization factor. ASEAN is needed for the stability of both in economic and political order in East Asia. Japan has to further promote its cooperation with ASEAN to help its solidarity as an association. 24 refs., 21 figs., 25 tabs.

    The paper surveyed the coal situation and energy situation in India and Thailand. The Indian coal is bad in quality. The subject is how to drill and treat the coal with such quality in future in accordance with changes in demand for coals as a coking material and as materials for the chemical industry. For it, it is a must to make studies for coal quality, reforming technology, and utilization method. It is also necessary to reinforce transportation facilities for carrying coal to places for consumption. However, even it is the technology introduction or the geological survey, the Indian people won't accept it unless they are convinced of it. On the contrary, engineers of Thailand have a methodical side, but on the other hand they have considerable flexibility. They accept the technology and maintenance introduced as they are. Concerning how to use it, they have strength which is more than that in the country which transferred technology. In Thailand, there are various kinds of rich energy resources, and therefore, it is thought that their ignite policy will be changed. More increase in ignite production depends upon how much the consumption of energy except electric power will increase. (NEDO)

    With an objective of promotion of geothermal development in the Otaki area in Nagano Prefecture, precision structural test well drilling and investigation works have been carried out, and the result thereof reported. The investigated area is an inclined land with an area of 70 km{sup 2} at altitudes of 1,000 to 2,000 m in the southern foot of the Mitake volcano having Otaki River as the southern border. The investigation has performed during the period from March 2 to September 30, 1987 the drilling of the N61-OT-5 test well hole (depth of 502.0 m), temperature logging, temperature restoration test, water injection test, and core test. The result of the investigation may be summarized as follows: existence of the stratigraphic succession as predicted by ground surface investigation, and existence of the Mesozoic and Palaeozoic strata of the Mino belt were verified; the Mesozoic and Palaeozoic strata of the Mino belt being the base bed have only small cracks, and very little alteration can be identified; X-ray diffraction of powder from test drilled cores recognized very little minerals altered by hot water; and the temperature logging and temperature restoration test identified no temperature indication that clearly indicates existence of heat sources. As a conclusion, there is no alteration due to hot water down to 500 m below the surface in the vicinity of the investigation well, and the possibility of a geothermal reservoir to exist is extremely low.

    In the Kuwanosawa area, Yuzawa city, Akita prefecture, survey was conducted to grasp effects of drilling for structural boring in the geothermal survey on the peripheral environment. In the survey of animals, there were 5 orders/10 families/19 species of mammals and 10 orders/25 families/73 species of birds. Three kinds of precious animals were confirmed. There were 132 families/6,670 species in the flora. Three kinds of precious plants and three kinds of precious floras were confirmed. During the survey, drilling for structural boring was conducted. At three spas for survey, there were recognized some survey items of which there were great fluctuations. However, those are seasonal valuations or valuations related to the situation of the inside of hot springs. It is not recognized that the fluctuations were caused by the drilling work and pumping-up of geothermal water. The noise made during the well drilling was reduced around the well as theoretical values indicated. At a spot 200m away from the well, the noise was reduced from the environmental standard, and accordingly, it seems that there are few effects on the peripheral environment. The vibration was reduced around the well more than theoretical values indicated. That was below the control level at a spot 25m away from the well, and it seems that there are few effects on the peripheral environment. (NEDO)

    This survey focused on the end of the more promising companion and promoting the international cooperation on chemical CO2 fixation and utilization technology. As a result, the way of the carrying-forward of the international cooperation with more than one companion could be arranged beforehand. It led to getting an arrangement about a secrecy agreement respectively with Lurgi company and ABB company in Europe, and to providing a catalyst sample developed by RITE to implement an examination by the other party and to show related technical information. In addition, it concluded a cooperation agreement about a total system of the chemical CO2 fixation and utilization technology and methanol synthesis with ZSW. In Australia, negotiation about international cooperation with CSIRO which is a federal research organization and CRC (Cooperative Research Centre) for renewable energy has been started. The ideal circumstances are being ready for the chemical CO2 fixation project for which the international cooperation with the country where the natural energy is rich like Australia is essential when coming to practical use. To do alternating current with further high density in the following year it is desired to build a concrete study cooperation system. 1 fig., 4 tabs.

    Drilling and survey of deep geothermal exploration wells were conducted to grasp the existing situation of deep geothermal resource and the whole image of geothermal systems in the area where geothermal resource was already developed. In the drilling work in fiscal 1994, 4000m-class rigs and the top drive system were planned to be used for drilling of 12-1/4 inch wells, but 9-5/8 inch liners were used for drilling down to depths of 2550m or deeper since the amount of lost circulation is large and the withdrawal of devices may be very difficult. And in 8-1/2 inch wells, the well was drilled down to a depth of 2950m. As to the deep resistivity exploration technology using electromagnetic method, studies were made of a multiple-frequency array induction logging (MAIL) method, a vertical electromagnetic profiling (VEMP) method, a joint analysis method, etc. Concerning the synthetic fluid inclusion logging technology, containers were lowered into the well and a comparison was made between data of the homogenization temperature analysis of the formed fluid inclusion and those of the temperature log analysis. With relation to the making of deep geothermal structural models, revision was made according to the determination of depths of Miocene formations, Pre-tertiary formations, and the Kakkonda granite. 65 refs., 268 figs., 79 tabs.

    The installation and introduction of photovoltaic power generation systems (PVS) in buildings are growingly expected in the construction field from now, coupled with the marketing of a solar cell module as a product for a construction material in the form of an external wall or a roof material for example. For this purpose, it is necessary at first to summarize problems that may arise at the time of or after the installation of PVS as a product. This paper examines an opinion poll, degree of recognition, current problems, etc., of PVS as a result of a questionnaire survey given to engineers and architects engaged in the actual construction business. The degree of recognition and interest was very high. Consultation or request for PVS installation was much more than predicted in numbers. Roughly 50% of the respondents reacted positively for the future installation request of PVS and, combined with the respondents who answered to look into the installation tentatively, not less than 90% were of a forward-looking opinion. The 85% of the respondents was not aware of the monitor business system for residential PVS. Further, the survey clearly brought out the importance of cost problems. 1 ref., 11 figs., 3 tabs.

    Although introduction of Joint Implementation (JI) and Clean Development Mechanism (CDM) have been adopted in the COP3, the details of how to set up the baseline for calculating the emission reduction amounts have not been established. This survey/research project has sorted out various concept menus for setting the baseline, verify each menu, and positively propose the methodology in an international arena, in which merits and demerits involved in simplified approaches, which try to simplify the works for setting the baseline, are analyzed, and their effectiveness is investigated. At the same time, both FCCC AIJ and NEDO AIJ projects are analyzed, to understand characteristics of baseline-setting method adopted by each project. There are many project types, to which direct application of any simplified approach is difficult. It is therefore realistic to analyze the situations case by case for the time being, and pursue for possibility of standardization of the baseline-setting methods after sufficient experience and data are accumulated to allow classification of the projects by common features.

    For the purpose of reducing the risk to accompany the exploitation of deep-seated geothermal resources, investigations are conducted into the three factors that govern the formation of geothermal resources at deep levels, that is, the supply of heat from heat sources, the supply of geothermal fluids, and the development of fracture systems contributing to the constitution of reservoir structures. In the study of deep-seated geothermal models for the Kakkonda area, a reservoir structure model, a thermal structure model, and a geothermal fluid/hydraulic structure model are deliberated. Then, after studying the relations of the said three structure models to fracture systems, the boundary between the geothermal fluid convection region and the thermal conduction region near the 3,100m-deep level, the existence of high-salinity fluids and the depth of gas inflow, the ranges of shallow-seated reservoirs and deep-seated reservoirs, the trend of reduction in reservoir pressure and the anisotropy in water permeability in shallow-seated reservoirs, etc., a latest reservoir model is constructed into which all the findings obtained so far are incorporated. As for guidelines for deep-seated thermal resources survey and development, it is so decided that deep-seated geothermal survey guidelines, deep-seated fluid production guidelines, and deep-seated well drilling guidelines be prepared and that assessment be made of their economic effectiveness.

    A survey was performed on the current situation in the Kuwanosawa district in Akita Prefecture to identify influence on the surrounding environment due to drilling of geothermal structure testing wells. The survey on animals covered mammals of five divisions, 10 families and 19 species, Aves of ten divisions, 25 families and 73 species, reptiles of one division, 3 families and 6 species, Amphibia of two divisions, 6 families, 9 species, and Insects of 17 divisions, 179 families and 719 species. Precious animals of a several species including black salamander were identified. In the plant survey, 132 families and 670 species were identified, with several species listed as the precious plants. In the survey of hot springs, those at three locations were all high-temperature hot springs at as high as 53.8 to 96.9 degrees C. Amount of discharge, pH and electrical conductivity differ largely by the hot springs. The hot spring in Takamatsu did not show large variation throughout the survey period. The Ogura Inn at Doroyu Spa has small variation in pH and hot spring temperature, but large variation in the amount of discharge and Al{sup 3+} concentration. Correlation was recognized between hot spring temperature and amount of discharge, between hot spring temperature and anion, between amount of discharge and electric conductivity, and between amount of discharge and anion.

    As a part of the FY 1999 geothermal development promotion survey - Akinomiya area survey, the rising speed/vertical permeability of the fluid associated with the natural flow were calculated by grasping the temperature of geologic layers/reservoir pressure in the survey area and the temperature distribution for vertical depth. In the survey of boreholes in the Akinomiya area: N9-AY-3, N10-AY-6, N10-AY-7, N10-AY-8, temperature/pressure logging was conducted in the stationary state at the time when a lot of time passed after drilling, water-filling test and jetting test having been finished. In the temperature/pressure logging, the continued measurement was made using PTS logging device to simultaneously measure temperature/pressure/impeller revolution number and lowering measuring device. As a result of the survey, it was assumed that there is a possibility of occurrence of the borehole fluid flow around the depth of 980-1290m and 1320-1540m of N9-AY-3 and around the depth of 880-1090m of N10-AY-8. The rising speed and permeability of fluid from each well indicated the same order at three wells. (NEDO)

    Efforts have been under way to prepare inter-industry relations tables and energy data for four Asian countries, namely, China, Taiwan, Singapore and Malaysia, and a tool for energy consumption efficiency analysis has been developed and improved. In Chapter 1, energy supply and demand in the above-named four countries is reviewed on the basis of recent economic situations in these countries. In Chapter 2, bilateral inter-industry relations tables usable under the project are employed for the analysis of the economic status of each of the countries and energy transactions between them, and a method is described of converting the tables into one-nation inter-industry relations tables which meet the need of this project. In Chapter 3, national characteristics reflected on the respective energy input tables are described, and a method is shown of converting a nationally characterized unit energy table into a common unit energy input table for registration with a database. In Chapter 4, the constitution of the Asian energy consumption efficiency improvement analyzing tool and a system using the tool are explained. In Chapter 5, some examples of analyses conducted by use of the analyzing tool are shown, in which the energy saving effect and CO2 emission reduction effect are estimated for Indonesia by use of the analyzing tool.

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

    A survey was made in India which is a coal producing/consuming country following China in Asia and where coal is used for about 60% of the primary commercial energy. The survey was conducted on coal production/distribution/utilization and environmental issues, aiming at studying feasibility of introducing the environmentally friendly coal utilization system into every industry including the residential/commercial one, and at implementing a comprehensive master plan including Japan`s international cooperation. Total power source facilities in fiscal 1995 are 83.3 million kW, 64% of which are coal thermal power facilities and generated 260 TWh, 69% of the total output energy. Main commercial energy sources are coal, oil and natural gas, and oil is self-sufficient. The survey this time did not examine very well the actual state of the environmental pollution problem caused by the coal utilization. Indian coal is high in ash content but low in sulfur content, and therefore, SOx polluting air has not been a very important problem so far, but soot/smoke is almost the problem. Further, ash treatment after combustion at boilers, etc. is expected to be a big problem in the future. 49 figs., 88 tabs.

The details of each place were reported in terms of the following: outline of the implementation, map of the place and booths, opening ceremony, management at entrance, dome theater, place for enjoying/relaxing, festival plaza, parking lot, PR related works, etc. In Festa in Yokote, more people gathered than expected. The reasons seem to be: the festa was held in the existing amusement facilities; the show using costumes of popular characters and gifts of the lottery were effective. As to new energy and clean energy vehicles, appeal was made mainly by stamp rally and questionnaire survey. By moving people inside the place, it helped people to have an understanding of clean energy vehicles. Almost the same effects were recognized also in the other places. (NEDO)

    With relation to the coal of Indonesia, where the expansion of the use of coal as a substitute for petroleum/plant fuel is aimed at, the paper grasped the situation of coal production/distribution/utilization and environmental problems, and analyzed the situation of the coal utilization/spread by industry including the commercial/residential use. The purpose of the survey is to work out a comprehensive master plan including Japan`s international cooperation for introducing the environmentally-friendly coal utilization system to Indonesia. Coal utilization systems, the introduction of which Indonesia should study in future, were picked up, according to the surveys in fiscal 1993 and 1994. In commercial/residential and small-scale industry sectors, needed is improvement of carbonization technology for production of coal carbonization briquette. Moreover, the introduction of bio-briquette should be studied in the future. In the power generation sector, studies should be made on the introduction of technology for SOx/NOx reduction and technology for coal ash treatment including the effective use of coal ash. For the introduction of coal boilers, the combustion mixed with bagasse, which is abundant in amount, is also necessary. In the coal production sector, coal preparation technology is studied, and a method to select the optimum process was proposed through the simulation. 76 figs., 43 tabs.

    For contributing to the formulation of technology development programs, an analysis is conducted based on the concept of value web into which the economic spread effect is incorporated. As information technology plays an important role in the fields of automobiles and chemical materials, there are various fields the research and development efforts exerted in which are common to many others. As to what additional values are created when such separately developed technologies cross each other, a discussion is conducted using techniques of industry-oriented analyses. Findings obtained are mentioned below. When the numbers of essays relative to the respective industries are compared, it is found that 63% of the total number of biotechnological essays fall on agriculture, the drug industry, and the food industry. On the other hand, when it comes to the produce, related industries larger in marketing scale is more strongly influenced by the spread effect. The spread effect of biotechnology is distinguished in the drug industry, and that of information/communication technology in the information industry, electric and electronic industries, and in the semiconductor industry.

    Trends of research on carbon based composite materials were surveyed through studying various reports and technical literature and evaluation of the project named above was conducted through holding interviews with researchers. In the survey of research trends for which technical literature perusal was the main tool, it was found that in most technical articles the important task was the enhancement of oxidation resistance, that SiC coating was in use for this purpose, that the technology would meet its limit at 1,600-1,700 degrees C, and that it would turn useless at temperatures beyond 1,800 degrees C. For the evaluation of the project, interviews were held with nine researchers not taking part in the project. The researchers favored the project as far as the popularity of the project and the main implementing body and system were concerned, but they negatively evaluated the project's goal of using such materials at 2,000 degrees C in the atmosphere. This research report comprises four chapters which cover (1) trends of research on C/C (carbon/carbon) composites, (2) a summarized research report on C/C composites, (3) survey of patents associated with C/C composites, and (4) opinions expressed toward the project and the results of evaluation conducted on the same.

    This paper describes achievements in fiscal 1977 of patent information surveys on hydrogen technologies. Japan is most enthusiastic in developing the thermo-chemical hydrogen manufacturing method. While no noticeable patents were found on the electrolytic method, researches on membranes and electrodes are expected. With regard safety assurance, it is necessary to establish safety assuring technologies suitable for each stage of hydrogen manufacture according the flow of manufacturing, liquefaction, storage, transportation and utilization of hydrogen. Development of mechanisms to prevent hydrogen embrittlement and destruction (leakage) is especially demanded. Enhancement of economic performance and reliability of hydrogen fuel cells requires research and development in the whole fuel cell configuration and also in the fields of auxiliary devices, in addition to that for catalysts and electrodes. Few patents are applied for in solid electrolyte and molten salt fuel cells. The most noticeable problems in hydrogen combustion devices are prevention of reverse ignition, safety measures for colorless flame, and positive utilization of hydrogen combustion characteristics in mixed combustion. Inventions tackling squarely with these problems can hardly be found. It was difficult to discover contributive and effective technologies because the hydrogen combustion characteristics are widely different from those of other fuels. (NEDO)

    This paper explains different theoretical calculation methods used in gravity and magnetic force data analysis in geothermal resources survey. Analyzing the gravity data and the magnetic force data is capable of being applied with the potential theory. The increased speed and capacity of recent computers make easier the conversion of data into wave number zone. In relation with heavy magnetic force analysis, the paper explains such items as basic handling, IGRF remainder calculation, methods for topographic correction, conversion of primary and secondary polar magnetism and conversion of pseudo-gravity, coherent analysis, spectral ratio method, estimation of spectra by using MEM, spectrum moment method, heavy magnetic force simultaneously analyzing type modeling, constraint inversion method, and other methods. The paper further explains the sequential approximation method in magnetization calculation, methods for calculating equivalent magnetization distribution (methods by Bhattacharyya and Chan, and Nakatsuka), method for calculating equivalent magnetization distribution (method by O'Brien), primary and secondary polar magnetism conversion relation formulas, and theoretical calculation of spectral ratio.

    For the establishment of a CO2 measures introduction scenario which the world would accept, the latest information was collected, the DNE21 (Dynamic New Earth 21) model was improved, and simulation was reviewed. In fiscal 1998, simulation was performed for each district using an LDNE21 (Linear Dynamic New Earth 21) model, and an energy flow chart, energy balance table, and trade table were prepared and subjected to detailed deliberation. Studied were also conducted about the changes to occur in methanol production when the natural gas reserves and plant cost data were given different values. In the DNE21 model, the 'macro economy model' and 'warming damage function' were integrated, and simulation was performed for verification. Using a standard model compatible with COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change), comparison was made between a case in which different CO2 emission constraints were imposed on the advanced area and developing area separately and a case in which one and the same constraint was imposed on the world as a whole, and calculations were made about CDM (Clean Development Mechanism).

    In the existing heat supply plant in Samarkand City in Uzbekistan, feasibility study was conducted of the project aimed at energy conservation and reduction in greenhouse effect gas emission by introducing the repair/cogeneration system of the regional pipes superannuated. In the project, the following were planned: introduction of two units of 6MW class gas turbine cogeneration, introduction of boiler which can realize 90% of the thermal efficiency, replacement of the existing regional pipes with pre-insulated pipes with less water leak/heat loss, etc. As a result of the study, the energy conservation amount was 21,006 toe, and the amount of greenhouse effect gas reduction was 64,998 t-CO2/y. As to the effects vs. expenses, the energy conservation was 2.80 toe/million yen, and the greenhouse effect gas reduction was 8.66 t-CO2-y/million yen. The initial investment amount was 7.51 billion yen, the business profit was 468 million yen/y, and the internal earning rate was 1.133%. It was judged that great profitability was not expected for the project, but the profit was returnable on investment. (NEDO)

    As part of the investigations on promotion of geothermal development, surveys have been carried out in the Oku-Aizu area to identify the existence and/or extent of effects of collecting geothermal fluids above the ground imposed on the environment, such as the natural ecological system. The investigated area is an area of 60 km{sup 2} covering Kawanuma County and Onuma County in Fukushima Prefecture, a mountainous area with undulations. The investigation result may be summarized as follows: the area shows the inland climate and has snow fall as much as 2 m in winter; according to the H2S diffusion prediction, the concentration thereof on the land in seasonal average is 0.7 ppm at maximum, which is a value presenting no problems. No fumarolic effects of SO2 were identified, and floating dust and Hg showed values that present no problems. With regard to water quality during and after the blowout test, no effects of blowout return were identified. The noise level was 41 to 45 phones at a place 100 m distant, and the vibration level has become the lower detection limit at a place 50 m distant. Leveling has discovered no ground movement. No variation in major constituents in thermal spring water was verified before and after the blowout test. (NEDO)

    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.

    Solar energy as defined by the United States includes hydroelectric power, biomass, and the ocean. The short-term strategy deals with passive solar air-conditioning, hydroelectric power, and biomass direct combustion. The medium-term strategy involves positive heating and wind power. The long-term strategy covers heat for agriculture, photovoltaic power, and OTEC (ocean thermal energy conversion), and the ultralong-term strategy covers power generation in space and photochemical conversion. Canada is behind other countries in the conversion of solar energy into power, and solar energy is used but passively as heat source, this because this country is rich in other resources. In West Germany, solar energy may be exploited for hot-water supply and heating at high latitudes, but it is not likely that it will be used for power generation. Home heating offers some appeal since potential demand for it is great. In Britain, the use of solar energy is not a pressing matter, this because systems for effective use of coal have long been established at homes, society, and industries in this country, rich in coal resources and enjoying oil from the North Sea oil field. France's efforts include biomass exploitation. In its development efforts, importance is attached to home heating, hot-water supply, and biomass. Next comes the conversion into power of solar energy. Photocells are also a subject of research and development. (NEDO)

    Feasibility study was made on the improvement project of the thermal efficiency of existing coal-fired thermal power plants in China to relate it to Japanese clean development mechanism. General study was made on the facility and operation of existing 300MW coal-fired thermal power plant units, and on-site study was also made on improvement of the thermal efficiency of some typical power plants. Based on these studies, effective improvement measures were identified, and general evaluation was carried out based on a cost effectiveness. The study result showed that the total efficiency improvement measures improve the plant efficiency of a standard 300MW unit by nearly 4%, and reduce CO{sub 2} emission by 184 ktons/y. The efficiency improvement measures for 10 300MW units by 2010 are estimated to reduce CO{sub 2} emission by 1.84 Mtons/y in 2010. This reduced emission is equivalent to annual emission of one 300MW unit. This project is reasonable enough if the cooperation range between Japan and the other country, and a source of funds are clarified. (NEDO)

    Borehole N11-KN-1 was digged and investigated for clarifying the geothermal structure of the Kuwanosawa area, with attention fully paid to the existing survey results. The hole is inclined, 1,802.30m deep in total, with a casing pipe installed down to the 1,101.76m level. Temperature was measured and electrical logging was performed at levels 410m, 1,110m, and 1,802.23m while the hole walls were still exposed bear. The maximum temperature of 161 degrees C was observed at the hole bottom, and the product of permeability - layer thickness transmission coefficient was described by 3.72 to 4.75 times 10{sup -1} darcy.m. The geothermal structures in presence in the south-western part of the survey area and along the Wasabizawa fault were made clear, and it was found that there exists no high-temperature water system in the vicinity of borehole N11-NK-1. As tasks for the future, it was proposed that a geothermal survey of the south-eastern part which includes borehole N57-YO-2 and a geochemical survey of fluids including hot spring water and surface be conducted.

    The research covers the Tsujinodake district spreading over Yamakawa-cho and Ibusuki-shi, Kagoshima Prefecture. Hot spring water in the district is of the neutral Cl type, heated mainly by conduction and containing seawater. The thermal water layer of the highest geothermal potential exists in the vicinity of the Nishi district of Ibusuki-shi. It spreads widely in the westward part and may be linked with the Unagiike district. The temperature of the deep-seated thermal water layer is estimated at 220-230 degrees C, yet it may be higher. In addition to the layer in the vicinity of the Nishi and Unagiike districts, there is a shallow-seated hot spring aquifer in the Nagasakibana district, where the deep-seated thermal water is probably prevented from lifting in the presence of an aquiclude. In the Narikawa district, possibilities are low that the thermal water just beneath will come up. As for hot spring water in the Oyama and Okachogamizu districts, there are no signs of high-temperature thermal water infiltration. In these two districts, it appears that hot spring water is heated by conduction over a large area. For the disclosure of linkage of hot water systems and deep-seated geothermal structures which cannot be detected by geochemical investigations conducted into hot spring water, etc., it is necessary to resort to geological and geophysical researches, and to carry out test drilling.

    For working out a new energy vision in Okinawa City, an investigational survey was conducted, as the initial-stage survey, of the state of energy demand of the city, estimated amount of existence of new energy, proposed project (draft) on new energy introduction, etc. The energy demand amount of Okinawa City was estimated at 6,865 x 10{sup 6} MJ/y. By sector, it consisted of 41.6% in the transportation sector, 35.6% in the commercial/residential sector and 22.8% in the industrial sector. The rate of energy source was 50.5% of petroleum-base fuel, 31.0% of electric power and 9.5% of LP gas. The expected minable amount of new energy was estimated at 318,513 x 10{sup 3} MJ/y, which is equivalent to 17 x the energy consumption amount/day of the city. As the proposed project (draft) for new energy introduction, study was made of the introduction of photovoltaic power system/solar heat utilization system to the children future zone park/elementary school/junior high school/kindergarten/public hall, introduction of clean energy vehicle to official vehicle of the city, refuse incineration power generation/utilization of incineration heat at Kurahama sanitary facilities, and others.

    As a part of the FY 2000 geothermal development promotion survey, survey was conducted in the Shiro-mizukoshi area (about 10km{sup 2}), Kagoshima prefecture, the gradually-inclined area located at the southwest foot of Volcano Kirishima, and the results were summed up. In the survey, the following were carried out: surface survey such as geology/alteration zone/fracture system, high-density gravity exploration, electromagnetic exploration, geochemical fluid survey, core test by drilling three exploration boreholes, temperature log, temperature recovery test, water injection test, short-term jetting test, etc. N12-SZ-1 came across the reservoir associated with the ENE-WSW system fault at a depth of 1,085m. The result of the temperature log and the geochemical temperature indicated that the temperature of the reservoir was between 230 and 240 degrees C. However, the reservoir was regarded as the vapor heating reservoir heated by the high-temperature vapor which is thought to be the shallow ground water separated from the deep reservoir. N12-SZ-2 was a large lost circulation zone at a depth between 1,325 and 1,486m, which indicated that N12-SZ-2 came across the ENE-WSW system Shiro-mizukoshi fault. N12-SZ-3 seems to be the area into which ground water flows. (NEDO)

    The trend survey was conducted of global warming protection measures by participation in international conferences, scientific society meetings and lecture meetings, and by literature surveys. We participated in the international conference on ozonosphere protection measures. In the 9th meeting of the nations which concluded the Montreal Protocol, the strengthening of restrictions on methyl bromide was decided on. In the UNEP solvent technology selection conference and the OORG conference of the World Bank, reports were made on substituting solvents in Japan, activities supporting developing countries, and the developmental trend of urethane use foaming agent. In the international conference on ozonosphere protection measures, introduced were the present status of Japan`s ODA for developing countries and examples of success of the substitution in the solvent field. The paper included nine reports on CFC destruction technology related literature made public in the past one year. The paper also introduced a comparative study of de-HCFC substituting technology at U.S. Oak Ridge National Laboratory, U.S. EPA`s prediction of emission of fluorine 3 gas, the predicted value of HFC emission and trial calculation of contributing rate in all greenhouse gases by IIR, Green Peace and Elf Atochem, and NOAA`s measured data on SF6 in the atmosphere. 49 refs., 46 figs., 26 tabs.

    Surveys were performed on the foundation for technological innovation in Japan and other countries. Main findings obtained from the actual state survey were compiled from the two aspects of 'items having difference in international comparison' and 'main findings by nucleuses and functions'. In order to activate the economy stagnated in the 1980's, America has developed strong industrial technology policies under the initiative of the government to strengthen the competitive edge, and the result thereof appears linking with the briskness in the today's U.S. economy. In Japan, the non-competitive fund distributed uniformly to national universities and national research institutes accounts for the majority in the governmental research fund. In contrast, many of the research funds of the U.S. government are the competitive fund, whereas researchers perform their research works using these funds, including their own labor cost, and the competition is intense. America is regarded to have put a huge amount of national defense research expense and space development research expense into private business entities, which are playing a large role in developing advanced technologies. A great amount of governmental fund is injected concentratedly into researches of health, medical and bio-technologies. (NEDO)

    With an objective to promote technological developments smoothly, surveys and discussions were given on how the improvements in intellectual foundations are worked out inside and outside the country. In surveying the status of improving the databases inside and outside the country, it was disclosed that the databases both inside and outside the country are arranged under the auspices of the governments. The reason for this is considered because the intellectual foundation improvement is difficult to be established as a business. In order to structure a framework to put together and publicize the data including those possessed by the private sector, surveys and discussions were given on the interest among titles to intellectual properties, contractual relationship between the database improving parties and the data providing parties, relationship with taxation systems, and how the incentives should be provided for publicizing the data. In discussing a model case to utilize data acquired by the private sector, it was concluded that assistance by the governments is indispensable for the organizations for structuring and maintaining the databases to continue their activities independently. Among the data measured and managed at the national level, problems in the publicizing method thereof were discussed especially on the data related to ocean information. (NEDO)

    In an effort to find guidelines on how to proceed with geothermal energy development so that it may coexist with hot springs, investigations are conducted into cases of impacts on hot springs imposed by geothermal energy development activities. An impact is judged to exist when geothermal development results in a decrease or depletion of pumped or spontaneously welling hot spring water, change in the concentration of dissolved chemical ingredients, fall in water temperature, or in an increase in the amount of discharged steam. Keyword-aided retrieval of data from databases is performed, and geothermal magazines are referred to for information. There are articles reporting impacts imposed by geothermal development on hot springs in the Palinpinon area (Philippines) and 12 others and in the Corwin Springs area (U.S.) and 13 others. These articles carrying outlines and impacts of geothermal development are collected, put in order, and analyzed. Cases in which such impacts are found to exist are categorized into four groups and, in each group, episodes are differentiated from each other by the type of mechanism linking the aquifer and the reservoir which is the object of development.

    New energy technologies have had the subsidy institutions established in association with advancement of the technologies, and such introduction promoting measures developed as the introduction assistance and advisory project. To promote this development more effectively, it is necessary that different data related to new energies are put into order comprehensively and systematically to be retained as the basic data. Therefore, this paper collects and puts into order the latest published data on cogeneration from among other new energy technology areas, with main regard to system listing, specific introduction examples, subsidy institutions, and how other countries are working on the technologies. Hydroelectric power generation uses up head energy of water by installing power plants along a river from higher location to lower location. Similarly the cogeneration is a kind of multi-stage energy utilization (cascade utilization) system that uses up energy serially from as high oil and natural gas combustion temperature as 1,500 degrees C or higher down to temperature levels used for hot water supply and air conditioning as low as 45 to 50 degrees C. It generates electric power by using a thermal engine, and utilizes waste heat effectively. (NEDO)

    There is a possibility that machining technology using high-density energy beam will bring an epoch-making change to micro-nano area processing. In particular, a laser beam having high controllability is indispensable. This is a report of the fiscal 2000 survey. The survey was conducted on laser beam generation, control and nano-diagnostic techniques, micro-nano optics technologies and machining technologies, with the development problems and targets summarized. Laser beam generation/control technologies, which become the basic tools for micro-nano manufacturing, were investigated, as were inspection technologies for the purpose of checking the functions of nano structures created. Particularly, the investigation elucidated the significance of development of a femtosecond solid state laser based on a semiconductor laser and the control techniques of their phase. Further, necessity was emphasized in developing X-ray probing, infrared and terahertz spectroscopy which are essential for nano-diagnostic techniques. In optics technologies, the paper described the importance of photonic crystals which enable less-than-wavelength machining or electrical beam control using interference effect. The possibility of fabricating photocatalysts with nano-particles was also mentioned, as was the manufacturing of nano-functional structures. (NEDO)

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

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

    The mind-based technology (MBT) was investigated to be developed, for materializing the world where the human race and machinery live together without sense of incompatibility. Based on the human mind, the MBT is a technology to support the personal expression which respects the value judgment, diversity and individuality in the human life. For it, it is important to technologically comprehend the human mind and physiological/psychological state, and particularly, control the human will. In order to structure the social system in which the human race and technology live together, it is also important to build a life system information processing model which simulates the formation process to integrate the feeling, knowledge and conscience, together with an action system to be established. As an image to which the MBT is applied, support will be extended to the life fulfillment, personal expression and hearty communication. Development is expected toward the social security technology with robots living in the human society. Pursuing the mental richness and worthwhile life, the high-grade mature society needs the technology to communicate with the machinery gentle to the human race on the mutual interface. 21 refs., 8 figs.

In Korea, the self-sufficiency rate of mineral fuels is low at 23.1%, which is due to its import of crude oil from abroad. It consumes 177.92-million tons (in terms of oil) of energy for its economic activities, with energy saving measures expected to work effectively here. Indonesia's mineral fuel self-sufficiency rate is high at 84.3% because it is an oil producing country. The energy it consumes for its economic activities is 179.37-million tons (in terms of oil), and energy saving measures will work effectively here. Thailand is a crude oil importing country. Its mineral fuel self-sufficiency rate is 33.4% and the energy its economic activities consume is 53.08-million tons (in terms of oil), and energy saving measures will work effectively in this country. The Philippines is a crude oil importing country and its mineral fuel self-sufficiency rate is as low as 4.8%. It consumes 22.71-million tons of energy (in terms of oil) for its economic activities, and energy-saving measures are expected to take effect here. (NEDO)

    This paper describes the surveys in fiscal 1978 on the status of progress in research and development in the Sunshine Project. Identification, evaluation and analysis were given on the status of progress in research and development and developed technologies in each project. Items of information were provided to related organizations for the purpose of mutual information exchange. The subjects include solar heat power generation, solar beam power generation, solar energy air conditioning, hot water supply systems, geothermal applications, and coals. Project teams were organized to discuss more precise identification of the current status of research and development, and increase in efficiency of the research activities. Since the Sunshine Project (which had begun in 1974) is coming close to completing the interim programs in the first term in fiscal 1980, it is thought necessary to provide assistance such as provision of items of information both for each group and on the collective basis. The basic issues at the end of the first term include presentation of the second term conception to the persons responsible of the program management, clarification of the evaluation criteria, strengthening of horizontal communication and adjustment functions in general, and feeding back of the surveys on the status of progress. Putting the basic problems in individual projects into order indicates necessity of discussion on the voucher control system, procedures of disposing of facilities after the related researches have been completed, issues of creating initial market, and expansion of technological discussions.

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

    For the contribution to elucidation of the structure of geothermal reservoir in the Kaminoyu/Santai area in the southwest part of Hokkaido, jetting test/sampling of geothermal fluid/analysis of properties were carried out in Structural Drilling Well N2-KS-2. The induced jetting of N2-KS-2 was conducted by the air lift method in consideration of the well temperature, state of lost circulation while drilling and results of the water pouring test. As a result, the mean jetting amount of geothermal water was 202.4L/min. The total pumping amount was 559kL, which is equal to approximately 119 times as much as the volume of well. The maximum temperature was 95.9 degrees C, resulting in no steam jetting. The pH of geothermal water was 7.41-8.44, electric conductivity was 9,620-10,450 {mu}s/cm, and the Cl ion concentration was 2,204-2,545 mg/L, which are almost stable. Properties of geothermal water is classified into an alkalescent CL-SO{sub 4} type. As a result of the study, the geothermal reservoir of N2-KS-2 is basically formed by a mechanism of a mixture of the surface water and the deep geothermal water that is similar in isotope to the geothermal water of Nigorikawa production well, which indicated a tight relation in the origin with the group of Kaminoyu hot spring.

    As a part of the survey of geothermal development promotion in FY 1993, survey of geothermal fluid was made using a precise structure drilling well N5-AM-5 as exploration well in the Amemasu-dake area, Hokkaido. The induced jetting of geothermal fluid was carried out by the Swabbing method in the total number of times of 185 in 11 days at 10-20 times/day, but did not result in the jetting of geothermal water. The sampling of geothermal water was conducted by guiding the geothermal water that overflowed the guide pipe to the tank. The temperature of geothermal water indicated approximately 20 degrees C in the 1st time and 40-60 degrees C in and after the 2nd time every day. The electric conductivity of geothermal water was 2.033 mS/cm, chlorine ion concentration was 420-500 ppm, and pH value was 7.17-7.72. As a result of the survey, it was presumed that the geothermal water of this well originated in the meteoric water around the area and formed slightly supported by emitted volcanic matters. As to the geochemical temperature, the silica temperature indicated about 120 degrees C and the alkali ratio temperature did about 180 degrees C. It was considered that there possibly existed geothermal reservoirs of approximately 180 degrees C in alkali ratio temperature around the well. (NEDO)

    As a part of the survey of geothermal development promotion in FY 1992, chemical/isotopic analysis of fumarolic gas in the Yoshioka district was made to elucidate the underground geothermal structure in the west area of Mt. Aso in Kumamoto Prefecture. Items for analysis of fumarolic gas were 16 items including the temperature, concentration of non-condensable gas, CO2, H2O, CH{sub 4}, {delta}D(CH{sub 4}) and {delta}{sup 13}C(CO2). Items for analysis of condensed water were 9 items including pH, Na, NH{sub 4}, {delta}D(H2O) and {delta}{sup 18}O. As a result of the analysis, the main component of non-condensable gas of fumarolic gas was CO2, and the composition was similar to that of the fumarolic gas in the Yunoya/Tarutama district in the periphery. It was presumed that the origin and formation mechanism of fumarolic gas were also similar to those in the Yunoya/Tarutama district. It was presumed that the deep geothermal reservoir which is the source of vapor/gas generation was composed of the neutral or alkalescent geothermal water, and a possibility that the reservoir is connected with the deep geothermal reservoir in the Yunoya district was presumed from a viewpoint of geographical location.

    The paper surveyed the coal situation and energy situation in India and Thailand. The Indian coal is bad in quality. The subject is how to drill and treat the coal with such quality in future in accordance with changes in demand for coals as a coking material and as materials for the chemical industry. For it, it is a must to make studies for coal quality, reforming technology, and utilization method. It is also necessary to reinforce transportation facilities for carrying coal to places for consumption. However, even it is the technology introduction or the geological survey, the Indian people won't accept it unless they are convinced of it. On the contrary, engineers of Thailand have a methodical side, but on the other hand they have considerable flexibility. They accept the technology and maintenance introduced as they are. Concerning how to use it, they have strength which is more than that in the country which transferred technology. In Thailand, there are various kinds of rich energy resources, and therefore, it is thought that their ignite policy will be changed. More increase in ignite production depends upon how much the consumption of energy except electric power will increase. (NEDO)

    The project aims to prepare inter-industry relations tables and models for energy analysis for Asian countries and thereby to probe into relations between the industrial structure or the ultimate consumption structure and energy consumption. For the comprehension of energy consumption as broken by each industry, Asian nations' inter-industry relations tables and energy statistics are linked for the compilation of energy analysis oriented inter-industry relations tables, and the resultant tables are used for the metric analysis of industrial structures and energy consumption structures in these countries. The tables prepared this time are 1985 tables for Korea, Indonesia, Thailand, and the Philippines and 1990 tables for China, Singapore, and Malaysia. The Malaysian transportation sector needs to be improved in energy saving. In Singapore, energy saving is functioning effectively in the transportation sector. China's energy consuming industries are those involving coal, chemistry, steelmaking, ceramics, and earth and quarrying. In Taiwan, improvement needs to be made in the transportation sector. Korea should conserve energy in the transportation sector. In the Philippines, energy needs to be saved in businesses related to water supply, transportation, and fishery. Thai industries as a whole needs to save energy. Improved energy consumption efficiency is sought for in the Indonesian cement related sector. (NEDO)

    A long-term survey was conducted on the spurting properties and fluid properties of geothermal fluids, when boreholes N9-AY-3 and N10-AY-8 were used as spurting wells and N8-AY-1, N10-AY-6, and N10-AY-7 as reinjection wells. Conducted or investigated were pH, electric conductivity, chlorine concentration determination, static temperature/pressure logging, PTS (pressure, temperature, spinner flowmeter) logging with wells spurting, buildup test, sampler logging with wells spurting, fluid property survey, tracer test, and borehole N10-AY-8 pulsation with fume spurting. It was then found that the maximum spurting capacity of borehole N9-AY-3 was 65.7t/h in steam and 90.8t/h in thermal water at a pit mouth pressure of 1.30MPaG. Some decrease was detected for approximately one month after the start of spurting, but it was concluded that there would be no further decrease thereafter. The maximum spurting capacity of borehole N10-AY-8 was 10.4t/h in steam and 8.9t/h in thermal water at a pit mouth pressure of 0.24MPaG. Some reduction was detected in the flow of steam and in fluid enthalpy after the start of spurting, and it was inferred that there would be still further reduction after continual spurting. (NEDO)

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

    Research study was made on the current usage, technological development and future subjects of biomass energy. The current use of biomass energy over the world estimated to be nearly a billion t/y oil equivalent. This value is estimated to be only a part of a pure primary biomass yield of 73 billion t/y oil equivalent showing a large supply potential. The evaluation result of a biomass energy potential in the world by GLUE (Global Land Use and Energy Model) considering worldwide biomass flow and competition of land use showed that no change of land use form in advanced areas is predicted, and no production of new biomass energy from forests in advancing areas is also expected. Production of biomass energy from farm products is promising in advanced areas, while the potential of biomass residue is high in advancing areas showing the possibility of energy development. Development of new biotechnologies such as molecular control of bio-production functions is expected to increase biomass resources. 76 refs., 26 figs., 30 tabs.

    For the purpose of realizing `the affluence` sought in the Japanese economic society, the supply and preparation of products, service and environments friendly to human beings seem to be important. In the future, the development of products which are fully considered also of aged and handicapped people is more expected than the conventional manufacturing of products added with value. Especially in accordance with the rapid aging, from a viewpoint that the lowering of physical functions caused by aging has an exactly close relation with the response to products and the environment, development of the database of physical functions for the aged which is useful for the design is urgently promoted. First, the data to be supplied for database were selected. As to the selection method, the data required for database were defined by collection/analysis of the existing data, examination of the needs of enterprise designers, and analysis of daily activities. In the study of the database, the structure by which data can be effectively supplied was studied and verified by pilot database for extraction of the subjects and solution to the problems. 6 refs., 57 figs., 26 tabs.

    This report describes the effective utilization of coal ash discharged from general industry (general industry ash) as improving material of construction waste soil and deodorant for poultry industry. Coal ash is characterized by the pozzolan and self-hardening properties which are not shown in soil and sand. Coal ash having a large amount of free CaO in its composition has stronger such properties. Coal ash generated from fluidized bed combustor which is a kind of combustor of coal contains a large amount of free CaO, especially, resulting in the stronger such properties. On the other hand, coal ash has water and oil absorbing property due to its porous structure. To utilize these properties, the improving material of soft construction waste soil and deodorant for poultry industry have been selected. As a result of laboratory and field tests for the former, it was found that sufficient supporting force can be obtained. Since the protection of powder splash is required at the site, a humidification system has been developed, which can protect the splash by the humidification of 5%. The price between 500 and 1,000 yen/ton is suitable for the improving material of construction waste soil. The maximum price of the deodorant for poultry industry is 10 yen/kg. 14 refs., 40 figs., 49 tabs.

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

    In order to promote technical cooperation of Japan with Asia in the energy aspect, site surveys were carried out on improvement in energy consumption efficiency. Electric power supply in Cambodia is made mostly from EDC, whose power generation amount in 1997 was 310 million kwh, while the power sold was 230 million kwh, with 26.1% of the total generation amount, or 80 million kwh being wasted as the loss. Existing power generation facilities are old and small in scale, made by the former Soviet Union making the repair difficult. The loss is enormous because of aging in power distribution facilities, overload operation, and power stealing. The efficiency is extremely poor, whereas improvement in efficiency of the existing facilities is indispensable to cope with the anticipated increase in the demand. In Bangladesh, 90% of the power is generated by using natural gas produced in the eastern part of the country. Many power plants are experiencing decreased efficiency due to the facility aging and insufficient and improper maintenance. The power transmission and distribution departments have had a large loss in power, which has become one of the most important issues. The loss exceeds 30%. The government is trying to achieve efficiency improvement in the electric power business through introducing the principle of competition by establishing new private companies. However, this approach is facing severe objection from the governmental and public labor unions, making the future development opaque. (NEDO)
