    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.

    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)

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

    It is necessary to establish scenarios for reducing CO2 emissions and for developing CO2 emission control technologies to obtain a global consensus, using appropriate analytical models. For modification of the DNE-21 (Dynamic New Earth 21) model, it has a category designated as innovative technologies not involving CO2 emission and an optional consideration for the absorption of atmospheric CO2 by biomass. A global carbon circulation model, including vegetation in its scope, is also incorporated. Major results of the simulation are shown. When 20% reduction in CO2 emissions is required for only OECD countries after the year 2020, it has been demonstrated that CO2 concentration in the atmosphere will reach as high as about 900 ppm in 2100 due to CO2 emission by developing countries, and will not be a tolerable level. Under the condition that CO2 concentration in the atmosphere is controlled at 450 ppm in 2100, the amount of renewable source of energy from photovoltaic power generation and biomass will increase and technologies of CO2 recovery and storage will decrease. Research and development of the production of methanol from recovered CO2 will be adopted as innovative technology for CO2 measures. 69 refs., 112 figs., 79 tabs.

    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.

    In order to fix carbon dioxide as a measure to mitigate global warming, research of large-scale revegetation of arid regions has been conducted toward the ultimate goals of systematizing revegetation technologies centered on securing and using water resources, evaluating the feasibility of arid revegetation by extending the viewpoint to examine even rainfall increase by artificial means, and establishing a strategic program for large-scale revegetation. A trial revegetation feasibility map was made for a selected target region in Western Australia, and rough revegetation steps were formulated. Selection of proper region, introduction of technology, and planning were conducted by grasping environment of the target revegetation region. As a result, it was found that growth of plants is vigorous at the catchment areas due to the surface water transfer along the topography of surface in spite of poor rainfall. Obstruction of plant growth is partly caused by the corrosion of soil and accumulation of salt, but mainly caused by the shortage of water. Based on these data, ranking of proper regions was evaluated. When the technology is introduced in the region with A-rank, several times of water can be collected. 60 refs., 61 figs., 30 tabs.

    Elaboration of the action plan for the New Earth 21 plan proposed by Japan in Houston Summit was researched. In fiscal 1995 three types of energy supply/demand scenarios, sensitivity analysis under various conditions, and cases presupposing CO2 emission regulations or not were evaluated by analysis toward 2050 using the New Earth 21 Model (NE 21 Model). Energy-saving is important, and CO2 recovery/treatment technology is introduced according to CO2 emission regulations, while attention is focussed on biomass energy. The issue of solar and wind power generation is cost reduction. In a presupposed horizontally integrated energy system, methanol represents an important intermediate energy. As a whole, CO2 reduction can be achieved by various combinations of energy-saving, introduction of regenerative energy, and CO2 recovery/treatment technology. Case studies of the action plan were conducted by unifying the evaluation criterion on coal IGCC, photovoltaic generation and biomass. The NE 21 Model was useful for elaboration of the reduction scenarios of CO2 emission. 26 refs., 84 figs., 28 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).

    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.

    Described herein are the results of the FY1994 research program for development of novel technologies for fabrication of high quality thin films of silicon for solar cells. The study on the mechanisms and effects of chemical annealing reveals that the film structure greatly varies depending on substrate temperature during the hydrotreatment process, based on the tests with substrate temperature, deposition of superthin film (T1) and hydrotreatment (T2) as the variable parameters. Chemical annealing at low temperature produces a high-quality a-Si:H film of low defect content. The study on fabrication of thin polycrystalline silicon films at low temperature observes on real time the process of deposition of the thin films on polycrystalline silicon substrates, where a natural oxide film is removed beforehand from the substrate. The results indicate that a thin polycrystalline silicon film of 100% crystallinity can be formed even on a polycrystalline silicon substrate by controlling starting gas composition and substrate temperature. The layer-by-layer method is used as the means for forming the seed crystals on a glass substrate, where deposition and hydrotreatment are repeated alternately, to produce the thin crystalline silicon films of high crystallinity. 3 figs.

    To proceed with the systematical arrangement of the new energy related data, this survey collected the data relating to fuel cells, and systematized them with the aim of making a data book related to fuel cells. Further, fuel cells are still developing, and therefore, the trend of development in this one year was roughly seen to make it the data toward the future development. This data book is composed of Part 1 (the world development trend in FY 1999) and Part 2 (data book). Part 1 was divided into the fixed power system (Chapter 1), fuel cell vehicle (Chapter 2), and selection of fuel (Chapter 3). The book has a big feature that the selection of fuel was added as an individual chapter, which is a difference from that of FY 1998. In the description of the developmental trend of fuel cell vehicle (FCV) in Chapter 2, the results of the present development and the trend were described in line with the subjects in achieving the commercialization of FCV. Part 2 is a data book which indicates the state of technology development of each of various fuel cells such as actual results of the demonstrative operation of fuel cells in Japan and abroad.

    To cope with the energy issue and global environmental issue, it is necessary to forcibly promote energy conservation. In the light of the present situation that in Japan only 1/3 of the primary energy consumed is effectively used, policies are being prepared for promotion of the introduction of high efficiency thermal utilization systems including `a project for formation of the environmentally friendly type energy community` promoted by NEDO. However, it is hard to say that the introduction is being actively promoted. The cause is that they do not fully understood the present status of high efficiency thermal utilization systems, procedures for introduction, subsidy system, etc. Therefore, a manual was made to present to self governments and enterprisers who are planning to introduce the system. To be concrete, there are the six systems: cogeneration use thermal supply system, unused energy use thermal supply system, heat storage use thermal supply system, waste use thermal supply system, plant surplus energy use thermal supply system, and cascade type thermal supply system. 28 refs., 38 figs., 42 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)

    Feasibility was studied of a demonstrative research concerning effective operation of a hybrid system consisting of photovoltaic, wind and diesel power generations in Myanmar. Upon confirmation of Myanmar's request and assistance, Myanmar electric Power Enterprise was selected as the counterpart, with Kantangyi village determined as the candidate site from the viewpoint of the quantity of solar radiation, wind conditions, and convenience in transportation service. Meteorological observation instruments were installed at Nyaung U observatory, with the observation implemented. It was grasped that the demand spreading pattern and the demand for electric power was 40 kWh/month per household. It was also judged that the system structure should be constituted of photovoltaic power, wind power, and diesel generator/battery/adjustable load. The problems are stable supply technology, technology for effective use of renewable energy, technology for complementary effects of photovoltaic power generation and wind power generation, and demonstration of a 100 kW class wind power generation system. Particularly important is consistency between the capacity of power storage equipment and that of diesel power generation. The study results applicable to Japan is the verification of a small-sized independent system for remote islands or the like. The total research expenses were estimated to be 600 million yen. (NEDO)

    Different environmental effects may be assumed when large-size photovoltaic power generation systems are installed in vast unutilized lands including deserts. Knowledge having been acquired to date has been put into order on the following subjects as the pre-survey thereon: (1) environmental characteristics of desert areas, (2) discussions on environmental effects from (a) environmental assessment viewpoints, (b) contents of the environmental assessment, and (c) environmental assessment institutions, and (3) the survey policy. In discussing the environmental characteristics, it is revealed that desert areas are neither sterile nor unused, but pasturage and agriculture have been carried out in historical and traditional ways. In discussing the environmental effects, it was recognized that surveys on primary and secondary effects on the environmental are indispensable. With regard to the institutions, there are countries who have and have not the institutions even among the OECD member states. In addition, it was known that environments in the desert areas vary greatly according to the particular areas, whereas there are possibilities of installing the facilities because the effects of the facility locations on the environment are various. Therefore, it was decided to start from the case studies in locations of different types. (NEDO)

The handbook differs in many ways from the conventional printed dictionaries or electronic dictionaries available at present. First, the handbook is compiled online and will be made available on internet for free access. Secondly, the handbook is corpus-based: the contents of the entry are written taking into consideration the actual use of the headword using the BCCWJ corpus. Also, it contains illustrative examples of a particular meaning culled from the BCCWJ corpus as well as those coined by the entry-writers. Third, the framework used in the description of semantic issues (polysemy network, cognitive mechanism underlying semantic extensions and semantic relationships among various meanings, etc. is cognitive grammar, which adopts prototype approach. Fourth, it includes audio-visual contents (such as audio files and animations/video clips etc. for effective understanding, acquisition and retention of various meanings of a polysemous verb. Fifth, the handbook is bi-lingual (Japanese-Chinese, Japanese-Korean and Japanese-Marathi and incorporates insights of contrastive studies and second language acquisition. The handbook is an attempt to share cutting edge research insights of various branches of linguistics with Japanese language pedagogy.

    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)

    Feasibility research was made on distributed power sources using photovoltaic and wind power generation in Tonga and Samoa. For the best mix of environment-friendly power sources, hearing from government leaders and power business persons, and field inspection were carried out. Foreign currency earnings of Tonga are dependent on remittance from nations working overseas, while since diesel fuel for power generation is expensive because of import through Fiji and tariffs, multi-power sources for power cost reduction and low-cost new power systems are in expectation. Underground transmission and distribution lines are under consideration to prevent typhoon damages. Both countries are probably rich in wind power potential, however, wind condition data are poor requiring further researches. Tonga government is in charge of power business except that in Tongatapu island. In Samoa, EPC (Electric Power Corp.) is in charge of power business. Hydroelectric power generation is possible because of rivers formed by abundant tropical rains. Feasibility research was made on coal-firing, fuel cell combined, wind power, photovoltaic and waste power generation. 7 figs.

    Nishimu Electronics Industries Co., Ltd. has developed a new series of inverters of three phase photovoltaic power generating system with the output ranging from 10 kVA to 50 kVA. For these inverters, the inverter and the system interconnection protector were integrated to make them smaller, lighter and cheaper. Stand-alone operation function was also added. The DC input voltage ranges were between 240 and 400 V for the crystalline solar cell, and between 170 and 400 V for the amorphous one. From the viewpoint of control of inverters, the inverters are generally controlled by the voltage-type current control method during the interconnection operation, while they must be controlled by the voltage-type voltage control method during the stand-alone operation which is the same as the UPS usually operated alone. For the present inverters, two control circuits for the interconnection operation and for the stand-alone operation were prepared. The control circuits for interconnection and stand-alone operations were switched using a cam-operation switch for change-over of operation. The results of the system interconnection verification tests satisfied the criteria of Japan`s Electronic Products Test Center. 3 refs., 4 figs., 2 tabs.

    As the research study contributing to implementation of 'The New Earth 21' proposed by Japan at the Houston Summit in 1990, a DNE21 model was developed as a quantitative assessment model for global warming preventive technology, heightening of efficiency of the global energy supply/demand system, conversion to energy sources of low carbon emissions, etc. In the project of 'The New Earth 21,' economy and environment can be compatible centering on developed countries' technical development and technology transfer to developing countries. In FY 2000, for heightening applicability of the DNE21 model, the world, which was used to be divided into 10 regions, was divided into 54. At the same time, a prototype model was constructed in which cities in the region were divided into three cities: large; medium; small. Using the DNE21 model, evaluation was made of effects of uncertainties such as population, economic growth, final energy demand and cost as preconditions of the model on the optimization of global warming preventive measures. Further, technologies which are expected to be important for global environmental policy in the ultra-long term were listed up to estimate the potentiality. (NEDO)

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.

    Recently the number of installation of the photovoltaic power system has been increasing. At present, the estimated introduction amount is 70,000-80,000 kW, which is still big in difference with the targeted introduction value. As seen in the increase in the number of installation, the trend toward the introduction is increasing, but there are left problems on the introduction such as 'the cost is high,' 'the information on the installation has not been well known.' Also in future, it is necessary to further promote the installation, tackling factors to hinder the introduction and making efforts to prepare for the introduction environment. In consideration of such background, in this guidebook, the items required when local governmental organizations, business operators, etc. study the introduction of photovoltaic power system were arranged. Also arranged were the outline and introduction samples of photovoltaic power system, general information on the introduction of the subsidy system, etc., procedures of planning/design, how to concretely introduce the related rules, various procedures to be taken, etc. For reference, the guidebook includes drawings of samples, data on the test field projects which have been carried out so far, data on solar radiation, etc. It is expected that the guidebook will be a help to the understanding of the photovoltaic power generation and will connect to further promotion of the introduction.

    For collecting solar radiation data necessary for the prediction of power to be outputted by photovoltaic power systems in Japan, detailed experiments and observations were conducted with an emphasis placed on the amount of solar radiation on a slope facing north and on the amount of solar radiation broken down by wavelength. Models were analyzed, and the fiscal 1999 results were compiled. In the validation of a model of solar radiation on an inclined surface, a review was conducted using the 1-year data observed at the Takasaki station for all directions, including solar radiation on the slope facing north, and the validity of the model was confirmed. As for the validation of a model for estimating solar radiation by duration of sunshine, it was examined for accuracy using the same data, and was found to be fairly high in accuracy. For the maintenance of solar radiation data for each wavelength, continuous observation was conducted for each wavelength of solar radiation at the Takasaki station using a multi-filter spectroradiometer, and a technique was established to determine spectral distribution using the observed data. Moreover, continuous observation of global diffused solar radiance was conducted using a sky scanner at the said station and solar cell power generation characteristics was continuously monitored.

    Research is conducted to properly deal with environmental problems, such as compromised solar cell safety, which may follow the mass introduction and diffusion of photovoltaic power systems. In the research of fiscal 1999 on technical literature on environmental measures against lead and animal tests, a need was found to reduce lead in power systems and to grasp lead elution characteristics for the establishment of environmental measures. In a safety test conducted for thin-film CIS (copper indium diselenide) based solar cells, basic data were collected about the vaporization rate of Se, the effect of moisture on the Se vaporization rate, etc. Basic data were also collected about the relationship between the combustion temperature and the amount of scattered lead in particular from the solder used as the conducting material in silicon based solar cells. In the evaluation of the environmental impact of thin-film CIS solar cells in case of fire, it was found that Se concentration below 10-20m in the plume was near the permissible concentration of 0.1mg/m{sup 3} as recommended by Japan Society for Occupational Health and that the concentration levels predicted for the periphery were two orders of magnitude smaller than the mandatory level.

    A comprehensive master plan for Shanxi Province was prepared jointly with China for the purpose of promoting rational use of energy and realizing an environmentally harmonious demand/supply structure of energy. This paper describes the fiscal 2000 results. The first phase refers to the surmounting of environmental problems incident to the use of coal and the restoration of regional economy. As countermeasures against air pollution in Taiyuan City, environmental measures were propagated such as simplified flue-gas desulfurization in thermal power plants, energy conservation in coke dry quenching, etc., and desulfurization of coke oven gas. Bio-briquette effective against smoke and soot pollution was carried out, as was general rubbish treatment (e.g., compost and coal/rubbish mixed combustion power generation). Promoted, by the opening of a clean coal center, were sulfur content reduction, coal briquette method, market expansion for CWM, etc. Producing city gas out of coal mine methane gas was also among the ideas considered. With the aim of attaining a Shanxi Province zero emission program, incentives are essential and, for this purpose, support by the national government is desirable including subsidies for investment, low-interest loans, tax deductions/exemptions, and yen-denominated loans from Japan. The second phase is intended for harmony with culture/science/nature, control of global warming and advanced utilization of coal. (NEDO)

    Described herein is a new hybrid solar power generator system, in which solar energy is separated into the light and heat components by a wavelength-selective filter before being directly converted into electric power, the former for the amorphous solar cell (ASC) unit and the latter for the thermoelectric unit. These units complement with each other to enhance overall efficiency. The ASC unit should have a higher efficiency when it works on the light component, because the heat (infrared) component increases cell temperature and decreases its output. For the ASC unit, the effects of the filter have been tested. The thermoelectric unit, generating power by the Seebeck effect, should have a higher efficiency, if heat flux passing through the unit can be increased, because of increased temperature differential, to which voltage produced increases proportionally. For the thermoelectric unit, heat is collected by a parabolic mirror unit from sunbeams received by a heliostat. Characteristics of these units are grasped almost as expected by the tests. 4 refs., 11 figs., 1 tab.

    Studies are performed to develop a simulation program for a stand-alone photovoltaic power generation system equipped with a lead acid battery. In this stand-alone photovoltaic power generation system, the load is connected in shunt with the solar cell array output through the intermediary of a lead acid battery and inverter. The program is a model in which the solar cell model is built taking parallel resistance into account, and the temperature-dependence of the constants is described using approximations experimentally obtained by Solar Techno Center of JQA (Japan Quality Assurance Organization), Hamamatsu. Insolation data for the model is described using METPV compiled by Japan Weather Association, and load data is described using data actually measured at Shizuoka. This program is compared with the data of operation at Hamamatsu, and the result is almost satisfactory. Simulations are conducted at five typical locations in Japan using this program, and it is found that the array load matching correction factor is dependent on seasonal changes rather than locality, that the battery contribution rate does not change much throughout the year, and that it is not dependent on locality. 5 refs., 7 figs., 3 tabs.

    In order to evaluate the simulation results of a photovoltaic power generation system, an operation simulation was carried out using the actual measured data of a stand alone PV system in Miyakojima, Okinawa Prefecture, so as to make a comparison with the actual operation data. The electric power was supplied to 250 houses and primary/junior high schools in the surrounding villages, which had an average demand load of approximately 90kw and the maximum of approximately 200kw. The power was supplied through the PV power generation in the duration of the sunshine, with an excess power charged in storage batteries and then supplied from the batteries at night. The array capacity was made 750kWp, the output current and storage batteries being characteristic type with an actual efficiency curve used for the inverter. The weather data used were the actual inclined insolation quantity and the outside air temperature data for a period of one month of November. The power charged in excess of 100% in the batteries was termed as an overflow power. With the charging condition 30% or less, a diesel generator was run for a rated operation for one hour, the power of which was termed as a backup power. As a result, the simulation was found nearly in agreement with the actual measurements. 5 refs., 7 figs., 2 tabs.

    The purpose of this verification survey is to confirm the performance and reliability with which a new large capacity capacitor works as power leveling use and partial power peak shift back-up use in the photovoltaic power system. The results of FY 1997 are as follows: (1) Verification using jelly-role type cells. (2) Trial manufacture of stacking cells. In (1), jelly-role type cells were manufactured using an electrode composed of aluminum foil and activated carbon layer and the organic electrolyte. The obtained cell capacitance was 6,000F on average and the energy density 5.4-5.6Wh/L. The experiment on the constant power load of a capacitor bank constructed with four 6,000F cells connected in series was carried out to confirm discharge energy of 25Wh between 12V and 3V. In (2), stacking rectangular type cells were trially manufactured by the electrode composed of two types of electrode; press type and sheet type electrodes. The cell capacitance was approximately 3,500F at sheet electrode cell, and the energy density 7.2Wh/L. To improve the cell performance, a relation was studied between the pore distribution of activated carbon and the double layer capacity, and the material higher than the conventional one in capacity per volume was found out. Studies were also made of trial fabrication of charge/discharge circuits and the experiment and the voltage balance. (NEDO)

    For Japan whose domestic reduction of greenhouse gas emissions is but limited, an approach to the problem with emission tradings and CDMs (clean development mechanisms) taken into consideration is necessary, and improvement on energy consumption in the Asian region as a whole is indispensable. From this viewpoint, countries in Asia who might be candidate importers of Japan's technical assistance were selected, and their energy conservation potential and farming village electrification potential were investigated. Covered by the survey were China, Philippines, Thailand, Vietnam, Malaysia, Indonesia, and India. Investigations were conducted into the fields named below, and the results were grouped into the same. The fields were (1) economic growth and energy supply/demand in the Asian region, (2) energy conservation in the Asian region, (3) electrification of farm villages in the Asian region, (4) cost analysis for farm village electrification in the Asian region, and (5) simulation of new energy introduction. The results show that there is a great difference between the seven countries in all the five fields. (NEDO)

    With an objective to prepare the basic map from among maps of geothermally promising areas in the south Kyushu and north Kyushu, comprehensive analysis has been performed from the standpoint of geothermal analysis by combining the data derived from remote sensing with the data obtained by different physical exploration processes. The analysis has used mainly the gravity data, magnetism data, radar lineament, and Landsat lineament, as well as the latest data processing technology and analytical methods. As a result of the analysis, the area around Kirishima in south Kyushu was indicated as the most promising area for the future geothermal development. This area contains a series of new volcanoes, has the fault systems grown widely, and is expected of existence of water permeable reservoirs in deep underground. The Kagoshima bay area and the Sakurajima Island area were also regarded promising. In the north Kyushu area, such promising areas were indicated as the Futagoyama area in which highly magnetized and high-density volcanic rocks are recognized, and moreover, penetration rocks with magnetic anomaly are recognized in wide area, the area with volcanic actions from the Pliocene period to the Quarternary period, and the area at the north latitude of 33 degrees 38 minutes, and the east longitude of 131 degrees 02 minute.

    With an objective to propose large-size system development scenarios assuming installations in deserts, the following investigations have been carried out: (1) collection of data on societies, economy, and energies in China and other countries where the large systems are assumed to be installed, (2) in order to reduce the costs, comparison was given on power generation cost by using a fixed tracking frame, a single axial tracking frame, and a biaxial tracking frame, (3) in order to evaluate the life cycle, discussions were given on the required energy inputs for system equipment, transmission and transformer equipment, and the installation construction to estimate the energy payback time (EPT) and CO2 emission unit requirement, and (4) discussions on development scenarios. In Item (1), while China expects on natural gas and atomic energy as the supply source, 80% of the energy would be supplied from coal in 2010. The development of new energies in India would further be delayed than in China. In item (2), the trially calculated power generation costs in Mongol by using the fixed frame, single axial tracking frame, and biaxial tracking frame were 8.72, 8.23 and 6.94 yen per watt. In Item (3) The EPT was two years or less in a 100-MW system, and the CO2 emission unit requirements in the silicon systems were 10 to 19 kg-C/kWh. (NEDO)

    This paper reports the result obtained during fiscal 1994 on a demonstration research on photovoltaic power generating systems. Solar cells with an output of 750 kW, storage battery facilities with an output of 3,058 kWh, three DC-AC converters with a rating of 250 kW, and a diesel generator with an output of 300 kW having been installed up to the previous fiscal year were combined to perform comprehensive adjustments and tests such as battery charge/discharge tests and AC parallel operation tests. The battery charge/discharge tests revealed that the 10 hour rate discharge capacity meets the specifications, and the batteries are free of deterioration after a demonstration operation of about 4.5 months. Difference between the power generation record and the planned value is thought due to the following reasons: the array output data in a power line connected system come about 90% of the simulation result due to correction coefficient for the solar cell conversion efficiency; the inclined face insolation results in less by about 7% than the planned value, and the transmittable power amount less by about 14% in total; the load power amount is less by about 7% than the planned value; and the balance supplementing power factor increases by about 4%. 5 figs., 2 tabs.

    Measurement was done on the annual power generation of a residential photovoltaic power system that was most suitable for the present situation in utilizing solar energy; and an examination was made on the basis of the data of a module in which an optimal operation load control was separately installed in order to operate the system more effectively. As a result, it was found that the introduction of a 3kW class system was currently most desirable as a residential photovoltaic power system, and that the problem of the optimal operation load control was crucial for the more efficient power generation. The resistance value of the optimal operation load was stable between 6 and 8 ohm in the daytime in fine weather. However, it was observed that, where no sufficient insolation was expected, the optimal operation load was ten times as much as in fine weather, being easily influenced by the environmental elements. In addition, it was revealed that, if the operation load was fixed at a specific value (6 ohm) in a clear day, the power generation was only about 85% compared with the case of controlling the optimal operation load. This figure was obtained under comparatively favorable conditions, however. 8 refs., 7 figs.

    In Candidate C area for the geothermal development survey, the natural environment was surveyed and `the secondary landscape assessment` was summed up in which places proposed for drilling of large-size wells and for construction of power generation facilities are extracted and a simulation of the landscape is conducted. The area for survey is the Shiramizu-gawa region in the south of Lake Akan, Akan-cho, Akan-gun, Hokkaido. The field survey was carried out about three items of landscape, plants and animals during the June-November period, 1995. As to the flora, diverse florae including vegetation unique to alpine areas, wetlands, and fumarole surrounding areas were found in the region, which is covered with summer-green broad-leaved forests or mixed forests of coniferous and broad-leaved trees. As to the fauna, faunae inhabitant of the highly natural forests were found including black woodpeckers and mountain hawk eagles. As a result of studying the places proposed for geothermal development from the above-mentioned survey, two places were picked up in the west of the survey area, where geothermal development is comparatively less influential in the natural environment and landscape and there is a high locational adaptability. 19 refs., 56 figs., 49 tabs.

    Intake manifold fuel injection type engines have a weak point that the emissions are not so good in transient operation, because the balance of fuel adhesion and evaporation goes out, so that three way catalyst does not work in good efficiency. For this countermeasure, it is effective to add feed forward control to conventional O2 feedback one. In order to achieve this feed forward control, the fuel table is necessary, and to make it needs enormous time and effort even for one target type engine. To overcome this difficulty, table making system was constructed, and expected result was obtained. 4 refs., 8 figs.

    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.

    Technology development of a solar power generation system is advanced in Japan taking the New Sunshine Subject (NSS) of the Agency of Industrial Science and Technology as the center. According to the initial stage plan (in fiscal 1993 to 2000) of the NSS, a general goal is to establish the technique which supplies electric power at the power generating cost (the production base cost) being equal to the electricity fees (20 to 30 yen/kWh) for normal families in the latest year. At present, introduction of the solar power generation system results in the reduction of about 1 million yen per kW. It is expected that 5 hundred thousand yen per kW is reduced by the present technology with a combination of cost reduction of solar battery modules, cost reduction of relevant equipment such as inverters, and rationalization of installation fees. It is necessary to realize 3 hundred thousand yen per kW for realizing the price having competition in the power supply market. In this paper, popularization prediction and popularization promotion countermeasures of the solar power generation system are concretely explained. (NEDO)

    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.

    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.

    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 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.

    In the geothermal drilling, reduction of the cost of well drilling is an important subject for technical development. The geothermal resource development tends to be made at higher temperatures and at deeper wells. In the present drilling technology, the cost is rising with the exponentially increasing depth and temperature, and there is also occurring the technical limit. Accordingly, the survey clarified the limit of the present drilling technology/cost to point out the research trend of the drilling technology as substitute for the present one, possibilities of the introduction, and the R and D target and subjects. As to latest drilling systems abroad and in Japan, the following were surveyed to study and extract promising technologies and systems: improvement/application of drilling equipment/materials (enhancement of heat resistance of the main drilling equipment, etc., cooling effects of top drive, heat resistance verification of MWD tools, PDM, tricone bits, multi-stage cementing tools, etc.), heightening of drilling rates, trend surveys of slim hole drilling, control drilling, well maintenance/workover, and well design technology. 68 refs., 73 figs., 40 tabs.

    Demands for constellation satellites were surveyed and satellite systems were studied for extracting basic technical tasks relative to constellation satellite systems and for drafting space verification plans. For a constellation satellite system to accomplish its missions, two or more satellites have to be simultaneously navigated. It is assumed that its field of application will cover earth observation, information communication, risk management, disaster prevention, and the like. With such applications taken into consideration, surveys and studies were conducted about the need and marketability of constellation satellites, need of state-level involvement, and requests for missions to be imposed on a constellation system. For plural satellites to satisfy mission requests by coordinating with each other, it will be necessary to develop basic technologies, such as navigational guidance, communications control, system autonomous management, and operation on the ground. Functions and performance that a constellation satellite system are requested to have and basic technologies to be studied and developed were extracted, and space verification plans were drafted.

    Observations are being made in Takasaki City, Gunma Prefecture on insolation, putting emphasis on the north side, and insolation by wavelengths to put insolation estimation model on the north side slope into order. This is an attempt to put into order by using the model the data for insolation on slope in all azimuth, taking the meteorological offices all over the country as the object. With regard to monthly average insolation, it was verified that the existing estimation model can be applied to the north slope in the Takasaki area, whereas trial calculations were performed on the average daily cumulative insolation by azimuth and inclination angle in the Takasaki observation points. As a result, it was made clear that the insolation onto north side roofs in Japan is about 70% of that on the south side. With respect to the time cumulative slope insolation, it was made clear that the Perez's cumulative model can be applied to the Takasaki area. Spectral distribution of global and scattered solar radiation was put into order by insolation to have verified that the stronger the global solar radiation intensity, the greater the occupation ratio of shorter waves increases, or in other words, the spectral distribution of the global insolation can be formulated. Sky distribution of radiation is being measured by means of measuring the sky scanning type radiation and luminance distribution. (NEDO)

    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.

    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.

    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.

    This report summarizes the result on selecting sites for large-caliber production wells, and landscape characteristic evaluation for simulation, based on the landscape survey on C candidate site for geothermal development. Field survey was made on landscape, plants and animals in the Kirishima Eboshidake area. It was clarified that this area has diverse flora including some rare species such as rein orchid and monkshood which are listed as endangered species. In addition, not a few epiphytes were identified. The zoological survey result showed that planted forests of evergreen coniferous trees which cover a wide range of the surveyed area, and peripheral grassland, scrub and natural forests provide good habitats for mammals such as sika deer and wild boars. On the other hand, no animal species in need of special protection were found. Geologically some traces of landslide occurrence in the past were detected in the northern part of the surveyed area relatively. As the survey result, some promising sites suitable for geothermal development were selected, which are judged to have a relatively small impact on natural environment and landscape. (NEDO)

    Photovoltaic power generation system was once placed in excessive expectation what with a growing tendency toward environmental issues and what with vulnerability in supply and demand of energy. However, its utilization was negative because of the low energy conversion efficiency and the high cost. Then, gradually the wind shifted round to the improvement in solar cell efficiency, reduced cost, implementation of subsidizing policy by MITI, purchase of excess power by electric power companies and the amendment of the Electricity Enterprises Act, encouraging the use of the system again. In addition, with a lesson from the Great Hanshin Earthquake, the merit of the system was appreciated as a life-support power source, motivating house-builders. Earlier, the authors had reported designs of energy-saving homes, system structures of photovoltaic power generation, etc. This paper presents the power generation record of a year old system and an example of the comfortable sealed residential room environment, etc., created with the use of the power thus obtained. The annual power generation was 4,088kWh, 30% of which was used in the house and 70% of which was sold as an excess power, resulting in the purchase of power for 6,642kWh. 5 refs., 4 figs, 2 tabs.

    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)

    Described herein are results of the natural environment surveys, carried out in the Shitanotai Region in Yuzawa City, Akita Pref., where Geothermal Development Promotion Survey C is scheduled. On-the-spot surveys, conducted from June to November, covered 3 items of landscape, vegetation and animals. The Shimonotai Region has a number of ponds and swamps, some of which are used as fields for Brasenia shreberi, and wet shield plant communities in places reflecting these environments. The zoological survey results show that moderate to dry deciduous forests of Japanese beeches (Fagus crenata) and Mongolian oaks (Quercus mongolica var. grossesserrata) in this region provide sound habitats for large mammalian wild animals, e.g., moon bears (Selenarctos thibetanus). For birds, there are some areas extracted indicating high possibility of being inhabited by honey buzzards (Pernis ptilorhyncus), which are listed as a near threatened species by the Environment Agency. Geologically, traces of landslide occurrence in the past have been detected widely, indicating need for more detailed investigation for land stability. These surveys have extracted several areas whose natural environments and landscapes are damaged relatively little by geothermal development. (NEDO)

    With the purpose of evaluating recoverable hot water quantity and elucidating the change over a long term, investigations were carried out, with the results summarized, on the geology, alteration zone, gravitational analysis, fluid geochemistry and hydraulics in the area. The investigations covered the area of 7 km x 6 km in about 30 km southwest of Sapporo City and were performed for the period from September 10, 1998 to October 31, 1999. The results were as follows. 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.

    A multi-hybrid system integrating photovoltaic and wind power generation systems with the existing diesel engine power generation system was assumed for installation in power systems in islands. System analyzing simulation and economic performance analyses were performed to consider system configurations suitable for islands from the viewpoints of system stability and economic performance. The work was progressed by dividing the subject into (1) research on the system configurations, and (2) studies on the economic performance. In performing either work, the power demand was classified as large (in Miyako Island), medium (in Kume Island) and small (in Tarama Island), and the introduction years into 1997, 2000, and 2005. In Item (1), the system parameter specifications were put into order, and the system analyzing simulation was performed, wherein it was verified that the system will be stabilized by introducing a system stabilizing equipment (batteries and an inverter) and by limiting the output from the wind power generation. In Item (2), it was made clear that the power generation cost is equivalent to or lower than the present cost, making reduction in fuel consumption possible. It was also disclosed that the introduction is most effective in small islands, and drop in the power generation amount due to limiting the output from the wind power generation is small. (NEDO)

    Possibility of practical application of dye-sensitized solar cells (Graezel cells) is discussed. Fine titania particle preparation conditions and titania thin-film electrodes were optimized and an energy conversion efficiency of 7.7% was accomplished. The screen printing method was applied to the manufacture of dye-sensitized electrodes, and performance governing factors were grasped. The use of the screen printing method resulted in a conversion efficiency of 6-8.4% when the factors were optimized. Though lower than the 10% in the Graezel report, values near that were obtained. The status of latest research and development is compiled involving studies about electron transfer dynamics in dye-sensitized solar cells, manufacture of sensitizing dyes and mesoscopic metal oxide thin-film, electron transfer layers and their physical properties, and solidification of hole transfer layers. Research was conducted aiming at their practical application, and tasks and problems in each of the said items were point out.

    Outlined herein are characteristics of solar radiation permeation in lean-to greenhouses provided with photovoltaic (PV) arrays on part of their roofs, and estimated quantities of power generated by the PV systems for different districts, seasons and cell areas. Three types of PV systems were followed; system 1: single-crystalline silicon, system 2: amorphous silicon, monolithically combined with the roof, and system 3: film-shape amorphous silicon. Annual quantity of power generated by these systems tends to increase as latitude decreases. They show an annual energy conversion efficiency of 10.3, 5.1 and 2.1%, respectively. Efficiency is unaffected by direction of the building on which the PV system is installed at low latitudes, as long as it is within {+-} 30deg around the east-west direction. At high latitudes, it is preferably in the east-west direction. For the PV system covering 30% of the roof area at a north latitude of 35deg, light received by plants in the greenhouse is fairly unaffected by the system throughout the year. These systems show a yearly solar energy utilization efficiency of 49 to 59, 46 to 55 and 44 to 53%, respectively, when they cover 60% of the roof area. 5 refs., 6 figs, 2 tabs.

    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.

Also carried out were sampling and constituent analysis at five points for river water of a wide area. The survey results were as follows. The pattern of change in spring water temperature was recognized such that it tended to rise in summer when river temperature was high and to fall in winter. Spring water temperature rose greatly at the time of higher water level like the thaw in some sources but conversely fell in other sources. The fluctuation trend in PH values was such that they mostly went up in April of snow melting time and in early August of much rain and went down in winter of little rain and less snowmelt. As for electric conductivity and dissolved constituents, it was recognized that the conductivity lowered and that the constituents decreased in concentration, all concurrently at the time of snowmelt and much rain.

    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)

    A geochemical survey was conducted by examining soil gas and hot spa water temperature for contributing to the clarification of the subsurface geothermal structure in the Hachijojima district, Tokyo. Mercury concentration, carbon dioxide gas concentration, and 1 m-deep temperature were measured at 155 sites; and chemical and isotope analyses were conducted for 10 specimens of hot spa water and 6 specimens of surface water. After examination, 5 significant locations were isolated at the regions of Yaene-Ogago, Taredo, the northern foot of Mt. Nishi to Weather Station, the southern foot of Mt. Higashi, and the region to the south of Mt. Higashi with hot spa distributed therein. The significant locations are situated in the vicinity of a mar that produced deposit by magma-steam eruption, an alteration zone, and the parasitic volcano in Mt. Higashi, and in an area with hot spa distributed therein. It is therefore concluded that they are closely related with volcanic activities. It is inferred that geothermal signs in the Mt. Nishi area reflect a relatively deep-seated structure. As for the mercury and carbon dioxide gas concentration levels in the Mt. Higashi area, it is inferred that they again represent geothermal signs reflecting a relatively deep-seated structure. (NEDO)

    Exploratory drilling and well survey were conducted, for the purpose of grasping underground geological structure, temperature and physical properties of Akinomiya area, Akita prefecture, as a part of fiscal 1998 investigation of geothermal development and promotion. The exploratory drilling well N10-AY-6 was excavated to the depth of 1,701 m. This well had a small lost circulation of about 4.2 kL/h at the end of drilling; hence, pressurized water injection was carried out for the purpose of enhancing the performance as a reducing well, resulting in an improvement to 21.6 kL/h. The well N10-AY-7 was in the bedrocks of the Old Tertiary system at the depth of 492 m or deeper, which revealed that the Old Tertiary bedrocks lay more shallowly than expected. At the depth of 1,900 m, the maximum temperature showed 223.3 degree C. In a temperature recovery test, it climbed to 277.2 degree C at the depth of 1,400 m. In the well N10-AY-8, the Old Tertiary bedrocks were found drilled at the depth of 87 m or deeper. Inside well temperatures at the time of temperature recovery test showed nearly the same degrees from the depth of 880 m to 1,090 m or about, thereafter rising until the depth of 1,330 m, further rising from 1,370 m until the bottom of the well, and showing the maximum temperature of 277.0 degree C at the depth of 1,450 m.

    For the purpose of elucidating a possibility of existence of geothermal reservoirs in the Haneyama area, Oita Prefecture, survey of the geological structure (geology/alteration zone) was conducted. The survey was made for the area of 280km{sup 2} lying from Kusu Town to Kokonoe Town, Oita Prefecture in terms of the route survey of 174km, fabrication/judgement of 52 rock slices, whole rock chemical analysis of 21 rocks, age determination, analysis of rock mineral, X-ray diffraction, literature collection, etc. As a result of the survey, the following conclusion was obtained. When considering a possibility of existence of heat source near this area, the area near the present volcanic front was regarded as promising. The fracture structure in the depths seen in the gravity structure (part of sharp dip of gravity) is more closely related to activity of geothermal water than the active structure of E-W system near the earth surface newly formed and is important when considering the existence of geothermal resource. The periphery of the Shishimuta sedimentation zone where Takigami, Oodake, Hacchobaru and Oguni are located was especially regarded as an area propmising of geothermal energy. In the survey area, the geothermal potential was the highest near Noya - Mizuwake Pass. (NEDO)

    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.

    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.

    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.

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

    This research arranges recent public transport system technologies such as LRT, and clarifies their technical issues to be overcome and developmental courses, and the improvement effect of their energy efficiency and CO{sub 2} reduction effect by such measures to contribute to development of next-generation public transport systems. The outlines and features of LRT, monorail/trolley bus and AGT as existing public transport systems are arranged. In the EU, development of tramways using rubber tires is in promotion. The concept of a next-generation environment- friendly urban transport system is prepared based on features of every public transport system. Since a trolley system causes traffic congestion and environment deterioration, introduction of an independent transport system with fuel cell is necessary in the future.

    For active environment technology export to OECD countries, needs for environmental measures in developing countries were surveyed. Both collection of environment technology needs in developing countries and preparation of technology seeds information of Japanese enterprises, and promotion of environmental projects by adding an information dispatch function are important. Active preparation and exchange of experiences and know-how of concerned enterprises, local governments and national organizations are also necessary. For development and possible export of small- and medium-sized ventures with excellent technologies and know-how, a suitable consulting system is essential for risks. For smooth promotion of warming prevention by international cooperation, active development of monitoring technology is also important. To support developing countries, OJT of persons in charge in technology transfer sites, and preparation of information infrastructure are necessary. Japan with much know-how on environmental preservation should positively participate in international standardization activities such as ISO. 10 refs., 14 figs., 56 tabs.

    The geochemical survey by the finger print method was carried out in the Okushiri Island area, Hokkaido, and places of fracture existence were extracted and districts of possible geothermal existence were estimated. The finger print method is a geochemical survey method of soil gas, and the soil gas was collected along the main roads and mountain streams at measuring intervals of 100-300m. The gas collector was buried 30cm deep from the ground surface for 17 days, and the soil gas that rose from deep underground was adsorbed/accumulated into activated carbon. The gas analysis was made by the high sensitivity Curie point pyrolysis/quadrupole mass spectrometer. As a result of the survey analysis, the existence of fracture zone was presumed in the district along the Shiromizusawa that is a branch of the Horonai River, district along the road of the Okushiri Island line and district 1.5km WSW from the 5.8K Pass. Further, out of all 12 specimens, 6 specimens of Type X were distributed in a group in the district 1km square in north, south, east and west with the top of Mt. Shokan almost as the center. The possible existence of geothermal reservoirs was presumed. (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.

    The present state and trend are surveyed of organic ferroelectric thin films, new carbon materials, fullerene compounds, and thermophotovoltaic (TPV) power. In the study of organic ferroelectric thin-film solar cells, the effort still remains at the basic stage, with the conversion rate as low as 3% in Europe and 2% in Japan. The progress of basic studies, however, is worth attention. It is deemed that 15% is the photoconversion rate to be currently expected from new carbon material solar cells. Fullerene compounds include some semiconductors whose bandgap values may be controlled across a 0.75-1.95eV range, and they may find their place in thin-film solar cells. However, their physical properties are not fully known, and their development into devices such as solar cells is scarcely reported. The research and development of TPV in the U.S. is led by NASA (National Aeronautics and Space Administration) and NREL (National Renewable Energy Laboratory), with their efforts concentrated on the development of portable power sources utilizing combustion heat. In Europe, TPV application to small-scale residential cogeneration systems is under study. (NEDO)

    The new technique, which continuously produced the monodispersion oil-in-water (0/W) emulsion using the crossflow type silicon microchannel substrate, was developed. On the silicon monocrystal substrate, the watercourse as the liquid of the continuous phase flowed was produced, and the column of the equal slit of the size in both walls of the watercourse was precisely processed. By closing the upper part in the slit by the clamp of the flat glass board in the microchannel substrate, the microchannel column was formed. Through the microchannel, the oil droplet in which the size was even was formed by sending out the oil (triolein) in the water (0.3wt% sodium lauryl sulfate aqueous solution) of continuous phase which is flowing in respect of the watercourse. The size of the oil droplet is greatly dependent on the structure of the microchannel regulated by microchannel width, microchannel height and terrace length (the even part of which the microchannel exit was equipped). Monodispersion emulsion of 16,20 and 48 {mu}m at the average droplet diameter was formed by using microchannel substrate of the three types of which the structure differs. Droplet diameter decreased, when the substrate which formed large droplet of 48 {mu}m in which the water current quantity is 1.4x10{sup -2}mLmin{sup -1} was used, when the flow rate increased. However, there was no a flow rate at droplet diameter, even if it was made to change from 1.4x10{sup -2} to 2.4mLmin{sup -1}, 16 {mu}m 20 {mu}m small change. In all cases, the droplet size distribution was narrow, and the geometry standard deviation was under 1.03. (translated by NEDO)

    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 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.

    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)

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.

    Survey and experimental research have been carried out on coal gasification using a pressurized internal circulation fluidized bed, spouted bed hydrogenation pyrolysis, supercritical water gasification, and a possibility of efficiency improvement by utilization of catalyst in chemical raw material production spouted bed gasification system. In the coal gasification using the pressurized internal circulation fluidized bed, an experiment was performed by using active alumina and Ni catalyst, where outstanding effect was identified. In the spouted bed hydrogenation pyrolysis, an experiment was executed by using iron hydroxide catalyst, but no noticeable effect was recognized. In the supercritical water gasification, an experiment was carried out by using Na{sub 2}CO2 and K{sub 2}CO{sub 3} catalysts, where it was found that the effect of the catalysts is little in the supercritical gasification reaction area of 800 degrees C. The power generation system composite with the chemical raw material production spouted bed gasification is a one-path system in which coal is gasified by the spouted bed gasification furnace, catalyst and steam are put into a heat exchanger to perform DME synthesis, and non-reacted gas is supplied as gas turbine fuel. Estimation was made on the possibility by an on-the-desk study, which requires experiments in the future. (NEDO)

    A soft switching method with small switching loss was proposed for the purpose of increasing the efficiency of a DC-DC boost converter which converted a DC current generated by solar cells to a variable DC current. Existing current converters are supplemented by using a snubber circuit around the switch so as to protect the switch by a hard switching action. However, with an increase of the output current, snubber loss is increased, reducing the efficiency. In order to solve this problem, the partial resonant switch method was applied to the converter; with this method of partially forming a resonant circuit only at the time of turning on/off of the switch, the switching loss was reduced through the soft switching, thereby making the proposed converter operate with high efficiency. Moreover, the resonant element of the partial resonant circuit using a snubber condenser, the energy accumulated in the condenser was regenerated on the power supply side without loss of snubber. With the regenerated energy, the proposed converter was provided with a smaller ratio of switching to use than the conventional converter. 4 refs., 7 figs., 1 tab.

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

    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.

    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)

    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.

    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.

    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.

    Commercialization feasibility of the SWD method has been tested and studied. This method uses a bit as the vibration source while a drilling is excavated, to collect information of geological structures and the like in front of the bit. In this study, the reflected and direct waves propagating from the drill bit while the N11-MD-3 drilling was excavated at the Busadake area were extracted and analyzed by the receivers installed on the surface of the earth, to estimate the default shapes which determine the geothermal structures. Analysis of the direct waves has statistically determined that the defaults are inclined at 81.5 degrees, based on the reasonable assumption. No reflection of the waves by the default plane was observed. However, it was observed that the waves were reflected by the stratum planes, when drilling was excavated to 1,006 and 1,008 m, and the results were used to map the reflecting planes. No reflecting planes with a default in-between was obtained, because of, e.g., limited depth sections and large stratum inclination. As a result, no default shape could be estimated. It is however confirmed that the SWD method produces reflected waves by bit signals even in a geothermal area, suggesting applicability of the method to default detection. (NEDO)

    System of the house is outlined, and warming performance and photovoltaic power generation system energy performance are taken up. It is a one-storied meeting hall situated in an apartment area, whose heat loss factor is 2.59kcal/m2hdegC. Ninety hybrid solar cells provided with circulating air heat collectors are installed on the east-side of the roof, interconnected to the commercial power system. In the daytime in summer, the house is fully insulated from solar radiation, with the room temperature kept a little lower than the open air temperature. The range of daily change in the room temperature is narrow, providing a comfortable residential space. When the windows are opened in the evening, cool air comes into the room to replace the warm air inside, reducing the difference in temperature between the inside and outside of the room. In winter, insolation time is short on the east side of the roof which finds itself out of the sun. Under the circumstances, the system outputs but a little and the quantity sold is quite small in winter. But, in summer, sale of power can be practicable, thanks to exposure to sufficient sunshine. The inverter rated at 3.5kW attains a 90% or higher operating rate in the presence of an input of power of 0.5kW or more. 4 refs., 10 figs.

    A solar pumped laser is reported, and the effect of the use of a CPC concentrator is experimentally investigated. In the experiment, a CPC corresponding to a 4 mm diameter 10 cm length laser rod is fabricated, and for collection of solar light a heliostat and a 10 m diameter, 3.2 m focal length parabolic mirror is employed. The experiment is performed in a time zone where energy of direct solar light is constant, i.e., at about 660 W/m{sup 2} and the maximum allowable angle of the CPC is at 53 degrees. Energy sent from the parabolic mirror is estimated to be 10.4 kW in total and is entirely collected on a 4 cm diameter focal flat plane. The utility of the energy is 0.13 % without the use of the CPC while being 0.46 with use of the CPC, and effective energy for use in the pumping is estimated to be 190 W, 670 W. As a result of the experiment, a laser output upon the use of the CPC is increased by 5 times, i.e., up to 10 W compared with 2 W without the use of the CPC. 2 figs., 1 tab.

    Study is under way for the development of a small power source system capable of supplying power to public facilities and home appliances at normal times and capable of turning immediately into a self-sustained power source in case of emergency. This study discusses a power source that is a combination of solar cell modules and a storage battery, which is subjected to analysis for its match with a light or a data-processing computer imposed as a load on the power source. In the experiment, the power source consists of solar cell modules and a rectangular wave inverter. The battery is a 12V/28Ah automotive battery, the solar cells are two 75W (17V/4.4A) modules, and the load is a fluorescent lamp, fan, electric bulb, or a computer. It is found that the system can operate near the maximum power point of the solar cell modules when the load is light and that the system still works on even when the load consumes more than what the solar cells module produce, this thanks to the battery serving as a backup. In the future, a test-dedicated small power source now under construction will be put to continuous operation for further study. 4 refs., 4 figs., 1 tab.

    For the preparation of a proposition concerning future research and development, surveys and studies were conducted centering about efficiency enhancement and cost reduction for the next generation ultrahigh-efficiency solar cell system. For improving the efficiency of the crystalline compound solar cell, studies were made about the prospects of the embodiment of a 3-junction and 4-junction types and of an increase in conversion efficiency expected to realize thanks to their light condensation behavior. It was inferred that anticipation of 29-47% conversion efficiency in 1 to 4-joint cells was theoretically acceptable. Four-joint structure cell fabrication would be a challenging task but would bring about an conversion efficiency of approximately 47% thanks to enhanced light condensation capability. As for cost reduction through the use of light condensation technology, surveys of overseas trends showed that the condensation-enhanced photovoltaic power system was characteristically fit for lower-price production. As for condensation and tracking systems, studies were made about cost calculation models of organizations involved in the United States and Europe, and then it was found that cost reduction in the optical system for condensation and in the tracking mechanism would be mandatory for the achievement of 75 yen/W.

    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)

    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.

    Survey was made mainly on use of biotechnology as resource saving and energy saving processes. Biotechnology is in wide use in a pharmaceutical field, while its application is on the increase in agriculture, food, chemistry, energy and environment fields. The USA is ahead of Japan and Europe. In the USA, there are more than 1000 ventures, and R and D of biotechnology, in particular, gene analysis and manipulation techniques are in progress together with acquisition of patents. In biomass energy, production of ethanol from corn, and development of biodiesel are in progress in the USA and Europe, respectively. Use of biomass should be promoted because of its global environment compatibility and sustainable productivity. In the future bio-market, genome analysis and its application are most important, however, Japan is behind in such technology in the world. The Joint approach by industry, university and government is necessary from the viewpoint of a future marketability and international competitiveness. Promotion of a public acceptance and nurture of creative talents are also important. (NEDO)

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.

    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.

    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.

    Researches are conducted on innovative mineral resources exploration technologies which use seismic waves or scattered electromagnetic waves to grasp the 3-dimensional structure in the ground. In fiscal 1998, a concrete research and development program is formulated, under which the seismic method and electromagnetic method will deal with an approximately 1km{sup 2}-large area of metalliferous deposit seated approximately 500m deep. In addition, researches are conducted overseas on the trend of related technologies. At an NMR (nuclear magnetic resonance) workshop held at the Society of Exploration Geophysicist, U.S., application of the NMR method to water is suggested. At a European Geophysical Society of environmental research and civil engineering event, useful knowledge is acquired about a 4-dimensional sounding (monitoring) technique in which a time axis is added to the 3-dimensional sounding technique and a high-resolution high-efficiency sounding system for probing shallow layers. During visits at Australian institutes concerned with the electromagnetic sounding technology, the trend of probing technologies especially those using the superconducting quantum interface device (SQUID) is gasped.

    In order to promote the joint implementation based on COP3, a survey and a discussion were given on improvement in wastes treatment systems and reduction of greenhouse effect gas emission in Tapioka starch manufacturing plants scattered in Indonesia. Currently, the wastes are disposed untreated, discharging methane gas into atmosphere as a result of putrefaction and contamination. Ten factories were picked up as the object of the survey. The following processes are to be adopted as the most suitable method for treating waste water and waste substances: solids (peels and fibers) are composted, and rinsing waste water is subjected to simple aerobic treatment; purified waste water is recovered of methane gas by means of anaerobic treatment; and the reduction amount of greenhouse effect gas converted to CO2 is estimated to reach 314,824 tons per year in total of the ten factories. If the carbon dioxide discharge right can be transacted at a sales price of a dollar per ton, assuming the compost sales price at 200 Rp./kg, the IRR will be 10% or higher, making the project very highly profitable. An IRR of 8% may not be assured unless the discharge right can be sold at 5 dollars per ton if the compost sales price is 150 Rp./kg. The Indonesian Government expects financial assistance from Japan for the pilot plant demonstration. (NEDO)

    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, a survey was performed on external accreditation systems for engineer education such as in universities and other organizations in the material field. In the survey, discussions were given on whether or not the education program accreditation system for the material field being structured has any problem in the actual operation of the accreditation through trials at Chiba Engineering University and Tokai University. As a result, it was revealed that the criteria are too general, requiring more detailed description on the guideline, and criteria should be so considered that assessment at higher levels can be given to the graduation research, which is a Japan's particular education system. In addition, it was made clear as a problem in the education programming side that a room for improvement remains in the education methods for the engineering ethics, communication skills, and the method for evaluating the students' achievements. In the survey on the methods for examination and accreditation in the U.S.A. it was found out that education organizations are perplexed with the new criteria of EC 2000. (NEDO)

    For the purpose of contributing to the spread/promotion of Japanese-make circulating fluidized bed boilers with desulfurization function, survey was conducted of the state of utilization of circulating fluidized bed boilers, the needs, etc. in China. In the survey, field survey was made at two boiler manufacturers and four companies using boilers in Beijing city, Fujian province, Hubei province, etc. to grasp the state of utilization and study conditions for the spread/promotion of circulating fluidized bed boilers. The Chinese government is making efforts for the spread of circulating fluidized bed boilers. The number of the domestically existing circulating fluidized bed boilers is estimated at approximately 800, but almost none of them conducts furnace desulfurization. Further, the operating rate of boiler is not always high. The reasons are as follows: desulfurization costs high without connecting to the production; environmental regulation is still mild in China; reliability and maintenance technique are still at low levels. It is urgently desirable to spread highly reliable circulating fluidized bed boilers with desulfurization function, and accordingly, it is necessary to reduce the cost of Japanese-make boilers.

    The project aims to contribute to the promotion of international research cooperation ranging from the survey stage through the stages of verification study and popularization, and, for this purpose, it conducts on-site investigations for exploring needs for environmentally-friendly energy-saving technologies in developing countries where there will be massive-scale oil consumption in the future. In this report, surveys and deliberations are conducted to embody proposed measures, and findings are compiled, based on the surveys conducted in the preceding financial year relating to energy efficiency in and environmental technologies for the textile and chemical industries. Much is expected from the proposed measures as promising subjects of joint verification researches. A technology is proposed for energy saving in the textile industry of Indonesia. The technology aims to wash cloth using high-pressure water from a special nozzle, to continuously measure the level of contamination of the waste water, and to feed back the measured values to the water supply side for the automatic optimization of the amount of the washing water and for the utilization of warm waste water for the ultimate purpose of cascade-aided energy saving. As for the proposition for recovering chemicals mainly caustic soda, it achieves environmental improvement and energy saving in the chemical industry simultaneously. (NEDO)

    For the purpose of contributing to working out a master plan for the introduction of the environmentally friendly type coal utilization system in the Philippines, analysis was made of the state of coal use/the state of spread by industry mostly including the electric power industry, cement industry and residential/commercial use fuel sector. In the Philippines, the amount of coal use has rapidly been increasing since coal-fired power plants started operation. For the promotion of the use of domestic coals, it is important to reform low grade coal. Moreover, the technology is required which copes with the reinforced regulation against SOx emissions. In the cement industry, coal and coal ash have not yet been effectively used. Therefore, the following measures should be taken to increase the competitive force: energy conservation measures, reinforcement of environmental measures such as dust prevention, and effective use of the fly ash emitted from power plants. In general households and small-/medium-sized industries such as tobacco drying, they still use a large amount of charcoals and firewood, which is approximately 86% of the residential/commercial use energy. There is a growing tendency for the development/spread of coal briquette as substituting energy. (NEDO)

    As a part of the survey of geothermal development promotion in FY 1991, electromagnetic exploration by the high accuracy MT method was conducted to acquire the information on the geothermal structure in the west area of Mt. Aso, Kumamoto Prefecture. The electromagnetic exploration was made in the area of about 65km{sup 2} at 52 measuring points for 3 measuring components in the magnetic field/2 measuring components in the electric field at 20 measuring frequencies or more in the range of 0.01Hz-20kHz for 4 hours or more. As a result of the survey, the resistivity structure indicated a 3-layer structure inside the Aso caldera. It was thought that the lowest layer was correspondent to the geological basement (Pre-tertiary system). As to the resistivity discontinuous lines extracted from sudden changes in depth distribution and resistivity distribution of the resistivity basement, those in NS direction are conspicuous and those in EW direction also exist inside the caldera. Around the part where these resistivity discontinuous lines of both NS and EW systems cross each other inside the caldera, the Yunoya hot spring and Tarutama hot spring which indicate the geothermal manifestation are located, and acid alteration zones were seen on the earth's surface in the periphery.

    Case studies were conducted of industrial refuse-fueled power generation using plastic waste, paper waste, and wood chips, and the same using the excretions of cattle. In the study of power generation fueled by mixed waste containing plastic waste, 325t/d, 220t/d, and 130t/d incinerators having the lower calorific value of 5,960-6,401 kcal/kg were taken up, and steam conditions, generator output, generating-end efficiency, station service power ratio, sending-end efficiency, etc., were tentatively calculated. As for cost efficiency, a manufacturer's estimate indicated that commercialization would be impossible in all the cases unless the construction cost was cut down. In the study of excretion-fueled power generation, cases were taken up where medium-temperature fermentation proceeded for the excretions of 620-29,853 dairy cows (32-1,576 t/d). A calculation was performed on conditions that the construction cost and maintenance/utility costs were as estimated by the manufacturer, that the excretion treatment and power generation facilities were covered by subsidies, and that personnel expenses of 6-million yen were necessary. It was then found that there would be commercial viability in case the yield was 790t/d or higher. (NEDO)

    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.

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

    The purpose of this research is to design pilot projects for introducing hybrid buses into the public transportation sector. This research also covers contents regarding hybrid buses with a trolley-collector motor and a diesel engine, to identify technical and economical problems and to analyze cost beneficiation using hybrid buses. The trolley parallel hybrid system has been employed for the feasibility study. This system has abundant operation results in Europe and the USA. Its battery is small or is not necessary, and the maintenance cost is also low. As a result of the feasibility study, reduction effects of CO2 emission were found out. When the CO2 generation at the power plant is not counted, the reduction effect was estimated to be 32% compared with the CO2 emission from diesel buses. When the CO2 generation at the power plant is considered, it was estimated to be 18%. The cost beneficiation was investigated for the cases of the transportations using trolley system surrounding a medium-scale terminal among large-scale housing development, tourist resort, and stations. The annual income is estimated to be larger than the annual payment in each case. It was found that the hybrid bus is economically established. 17 refs., 48 figs., 41 tabs.

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

    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.

    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.

    A model dealing with the temporal distributions of recreational one day travels has been proposed. The model works on basis of trade off relations between a long stay behavior of travellers and a short stay of the travellers taking account of the lateness of departure time, earliness of arrival time at home. But in the case of a short stay, degree of freedom of the time decision becomes big and the behavior types of the travellers vary severely. This paper describes an attempt to find a model to predict temporal distribution of recreational travels which do not take a long stay. Once transportation times are input to the model, the model will give the time of coming out of gardens and the departure time of the travellers. The model has been used in a case mentioned in the paper, it is clarified that the model forecasts successfully the time of coming in and coming out of the garden even though there are maybe some errors in the used data as the data is not collected enough. 1 ref., 9 figs.

    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 photovoltaic (PV) power generation system having a lot of merits for environment and energy has been put into a diffusion stage from the viewpoint of its technology due to its progressive technology innovation. However, it is not widely diffused in the whole society due to its high cost. Systematic investigation for the future PV power generation was conducted through the verification of factors obstructing the diffusion promotion and the investigation of the problems. Then, questionnaires were conducted for local governments in the Kinki district. Proportion of the local governments positively promoting the introduction of PV power generation was 3.4%. Among new energies, 45.7% of the governments were interested in solar heat utilization, and 43.1% were interested in PV power generation. Proportion of the local governments understanding the subsidy system of MITI was 57.7%. For the explanation meeting of new energy introduction promotion, 55.4% of the local governments wanted to participate. Among the interesting themes, 61.0% were interested in the introduction examples, 52.4% were in the introduction support, 52.1% were in the introduction of fundamental knowledge, and 30.0% were in the latest technology trends and in the guide for introduction

    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.

    With an objective to make clear the basic information about aged and handicapped persons requiring welfare goods upon the development thereof, this survey performed a questionnaire survey to business entities performing design, development, improvement and fitting of welfare goods. The questionnaire survey selected 879 business entities involved in manufacture and sale of the welfare goods. The effective reply recovery rate was 19.3%. The questions had the data contents required by products classified into body dimensions, motion capability, sensory functions, and work capability, asking to state data contents required for each item, reasons for the needs, and data sources. The data source currently utilized reveals that most of the replied enterprises utilize data derived from the company's own measurements, developments and experiences. The contents thereof indicate that the data are too old, the data contents do not match the current situation, and no required data are available. In designing, developing and fitting the welfare goods, the required data may not necessarily be obtained, whereas improvement in the database is strongly desired. (NEDO)

    Research was conducted in Vietnam for the development of a hybrid system comprising a photovoltaic power generation system and a micro-hydroelectric power generation system. In verification test operation, data measurement had been under way for approximately 18 months since it was started in September 1999. The rate of days on which effective data were obtained throughout this period was 93.4%. Power generated by the micro-hydroelectric power generation system was 19.4kWh/d with so small a capacity factor of 3.2%. The capacity factor of the photovoltaic power generation system was again very small at 4.5% since the amount consumed by the load was as small as 131.0kWh/d. Weather data of solar radiation and precipitation were being collected smoothly. In the study of hybrid system optimization, the effect of inductor generator activation upon the inverter was taken up. In the study of capacity balance optimization between the constituent elements of the hybrid system, methodology was established and verified, and calculations were carried out. (NEDO)

    Joint research was conducted with Myanmar on a photovoltaic power generation system interconnection system, for which fiscal 2000 results were described in this paper. Power generating facilities were set up consisting of 80kW photovoltaic, 40kW wind and 60kW diesel systems. With the photovoltaic and wind power generation connected to a small-scale power system as a ballast load, the system interconnection is formed through load adjusting equipment such as storage batteries. The hybrid system feeding is from 6 o'clock early in the morning until 23 late at night. The diesel power generation is free from restrictions. The operating method was set on system control (demand side management) by adjustment from the load side, with ballast load control employed that adjustably operates an ice machine load. The basic design was drafted in terms of a storage battery capacity of 1,000Ah and an ice machine load of 32kW. The daytime load was assumed to be 25% of the night load. On the equipment specifications set in this basic design, arrangement design was conducted for the equipment in the premises, making a land development plan and a basic construction plan including a temporary work site, construction steps, transportation and delivery of the equipment. Quantity of solar radiation and wind data were continuously observed. (NEDO)

    This paper describes the fiscal 2000 report on research data of joint demonstrative development with Myanmar concerning photovoltaic power generation system interconnection system. The purpose is an operation research in the case where a small-scale electric power generation system in an remote island or the like in Japan is linked with a severely output-fluctuating power generation system using energy of nature such as photovoltaic and wind power generation. In particular, among the system control (demand side management) methods by adjustment from a loading side, ballast load control was employed that adjustably operates load of an ice machine for example. As the contents of the data, the quantity of solar radiation and wind velocity at the Chaungthar site were shown as meteorological observation data. In addition, a graph was made on the meteorological observation data at the Chaungthar and Letkhokekone sites. The paper also explains the final explanatory data for selecting the sites in implementing the demonstrative research. As to the operation method of the hybrid power generation system, assumption was made for the daytime load in four cases from 50% (30kW) to 0% (0kW) of the nighttime. Storage batteries and diesel generators were installed and used in combination. Simulation results were also presented. (NEDO)

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

    It is important to cool a photovoltaic (PV) panel, because increased panel temperature is accompanied by decreased power generation efficiency. The authors have proposed a PV power generation system combined with an adsorption chiller driven by low-temperature heat, and simulated temperature changes during the desorption cycle, where the chiller utilizes endothermic reactions of an adsorbent during the desorption cycle. Described herein are results of the tests carried out to validate possibility of controlling panel temperature increase. The system consists of the PV panel with which a bed packed with an adsorbent is monolithically combined, condenser and evaporator. It generates power during the daytime by sunbeams, and provides low-temperature heat during the nighttime by the evaporator. In particular, ice can be produced when methanol and activated coal are used as the adsorbate and adsorbent. It has an advantage of effective utilization of energy as the heat source, which has been merely dissipated by the conventional system in the air. Such a system is expected to be useful for promoting effective utilization of solar energy and for peak power shaving in summer. The initial targets are achieved by the tests. 4 refs., 10 figs.

    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.

    As to the influence of spectral solar radiation to generating power of solar cells, a study was conducted from the aspects of season, time zone, intensity of solar radiation, etc. In the study, spectral responsive variation correction coefficients were introduced as evaluation values expressing the influence of spectral solar radiation. For the spectral distribution, an all sky spectral pyranometer by wavelength was used, and data were used which were obtained in the measurement in experimental facilities of the solar techno center. Concerning solar cell relative spectral sensitivity values, used were relative spectral sensitivity values of monocrystal and amorphous standard solar cells to the short-circuit current. Spectral response variation correction coefficients are coefficients correcting variations in conversion efficiency of solar cells due to changes in the spectral distribution. The changes of spectral responsive variation correction coefficients were studied using data obtained during April 1994 and March 1996. As a result, it was found that the coefficients showed large changes in summer and small ones in winter and that amorphous solar cells indicate this trend conspicuously. 3 refs., 6 figs., 3 tabs.

    In order to verify the complementary relationship between wind and solar energy, the long-term field test of the hybrid power system was conducted at the natural energy square of Ashikaga Institute of Technology. The solar cell blade windmill composed of a Savonius windmill and flexible solar cells applied to swept buckets was also prepared. As a result, the wind power generation was promising mainly in the winter period including the late fall and early spring, while solar one was stable all the year through although it was slightly poor in winter. Stable power generation was thus achieved by combining wind energy with solar energy. As the whole data of other wind and solar power generation systems at the square were analyzed for every month, the same conclusion as the solar cell blade windmill was obtained as follows: the wind power generation in Ashikaga area is promising in Nov.-March from the field test result for 16 months, solar power generation is stable all the year through, the hybrid power system is effective in Nov.-April, and the solar cell blade windmill is equivalent to the hybrid power system. 3 refs., 5 figs.

    This paper describes the operating characteristics of a stabilizing circuit using commercial electricity, those of a stabilizing circuit using solar cells, relation between the quantity of solar radiation and the maximum output of a semiconductor laser diode (LD), and simulation results of annual LD output in Sendai City. The stabilizing circuit for the solar-cell driven LD was structured such that the output of the solar cell panels was guided to a DC/DC converter, that the voltage was set at a prescribed value and that the current was stabilized with the use of power MOSFET. The solar cells used in the experiment were monocrystal silicone solar cells with the maximum output of 53W each. In the experiment, the LD was protected by stabilizing the current at a set value when an excess current was supplied to the stabilizing circuit. As a result of the simulation of the annual LD output from the meteorological data of Sendai City, it was predicted that a solar cell of approximately 1kW was able to provide an annual output of 102MJ and that the efficiency was highest with four sheets of the solar cell. Consequently, consistency proved to be essential between the LD and the solar cell output. 3 refs., 7 figs.

    A TDEM (time domain electromagnetic) surveillance was conducted for the Hachijo Island region, Tokyo. The survey covered a 70 km{sup 2} area, with 81 observation stations. There was a distance of 1 km or more between transmission electrodes, the signal was a rectangular wave with a cycle of 16 seconds or more, the sending current was 60 A or more, and the shortest distance between a transmission electrode and an observation station was 2.5 km or more. A subsurface structure model was proposed after the analysis of the collected data, which is described below. In the Mt. Nishiyama district, the deep-seated magnetic substance, high-conduction zone, and the low gravity anomaly zone were found to be roughly equal to each other in terms of distribution. It is inferred that the low gravity anomaly results from reduction in resistivity by the progress of fractioning of rocks due to the intrusion of a magnetized rock into the depth and from mass defect due to volcanic eruption. In the Mt. Higashiyama district, a high density rock intrudes in the ENE-WSW direction for the creation of a high gravity anomaly belt, and it is inferred that alteration occurred along the southern rim of the belt, that magnetic substance was produced in the cavity-abundant portion, and that a volcano with several craters rose at the middle of the portion.

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

In this fiscal year, the status of existing coal utilization technology and environmental issues in Malaysia are summarized as basic data for the introduction of above-mentioned systems on the basis of data and information collected by basic research and site survey in FY 1996. Malaysia is one of the rich countries producing the primary resources with crude petroleum, natural gas, hydro-power, and coal. The coal demand will be realized after saturating LNG development since 2000. The major coal consumption industries are power generation sector and cement industry sector. As expected increase in the future coal consumption, efficiency of coal utilization and environmental issues are problems in the future. Based on the FS results of this survey, the survey will be continued for planning and conducting the model project required from Malaysia. 8 figs., 34 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)

    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.

    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)

    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)

    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.

    Investigations were conducted into the above in some leading OECD (Organization for Economic Cooperation and Development) member states. Green chemistry is a new concept in which clean technology, environment-friendly chemistry, and the like are combined, and is a chemical solution for reducing or stopping the use or generation of materials, products, by-products, solvents, reagents, etc., which are dangerous to health and environments, throughout the whole life cycle of chemicals covering the processes of their designing, manufacturing, dumping, and recycling. In this fiscal year, the actual state of the generation of biomass, regarded as representative of reproducible materials, and its feasibility as chemical resources were investigated. In an effort at finding out chemical reactions safer to health and causing less environmental impact, investigations were also conducted into the recent trends of catalysts, novel reactions for organic syntheses, use of supercritical fluids, photocatalysts, biomimetic processes, etc. The development of substitutes for plastic additives was also studied. Since acceptance by the citizenry is quite important for green chemistry to take effect, educating and enlightening activities in the U.S., Britain, France, and Germany were inquired into. (NEDO)

    Reported herein are the survey results of hot water in the Kumaishi area, Hokkaido, as part of the FY 1996 geothermal development/promotion survey project. A total of 277 spouting guidance tests were conducted by the swabbing method for 10 days at the N7-KI-1 well, which, however, failed to achieve continuous spouting of geothermal fluid. A total of 144 swabbing tests were conducted for 8 days at the N7-KI-2 well. The geothermal fluid is spontaneously spouted out, although intermittently, after the main valve was opened, because it had a pressure of 4.1 kg/cm{sup 2} G at the mouth of the well from the first. However, the final self-spouting quantity remained unchanged in spite of the guidance works. The hot water had a pH 6.4, and contained Na as a cation at 8,940 mg/L and Cl as an anion at 14,500 mg/L as the major impurities. The associated gas was mainly composed of carbon dioxide, containing little hydrogen sulfide. The hot water spouted out through the wells contained Na and a high concentration of Cl as the major impurities, suggesting possibility of mixing hot water containing a high concentration of salt with surface water. It is considered that neither hot water nor its impurity concentrations are evenly distributed in the deep underground of the Kumaishi area. It is therefore considered that the deep underground hot water sources for hot spring slightly vary in composition and impurity concentrations. (NEDO)

    To obtain the basic data for improvement of the system in the fellowship project (engineer training project) and establishment of the evaluation method in Japan, survey was conducted. In the U.S., there are a lot of fellowship programs, which are aimed at undergraduate students, graduate students, postdoctoratas and professors. Each program has difference. Graduate students majoring in science use the system as a mechanism for supporting school expenses, and besides, there are various kinds of systems supporting school expenses. Recently, the number of American graduate students majoring in science hit the ceiling, and therefore, the fellowship system is re-recognized to be important. The fellowship system in the U.S. largely contributes not only to education of researchers but to increase in mobility of researchers. It is recognized that the mobility of researchers is indispensable for reinforcement of the industrial competitive force. The fellowship system is playing a more important role in the innovation of the US industry. (NEDO)

    Attention is paid to behavior at the molecular level with reference taken to the photosynthetic mechanism, and a behavioral mechanism is proposed, which incorporates, in place of the conventional band model, a concept of a molecular structure based on electron transfer, excitation energy transfer, and reactions of oxidation and reduction. Discussion is then made on elements of technology development for the embodiment of high-efficiency organic ferroelectric thin-film solar cells. The elements taken up include the feasibility of organic ferroelectric thin-film cells, photoelctric conversion systems of plants and photosynthetic bacteria, solar cells using donor-acceptor type dyes, organic thin-film solar cells using conductive polymers, and efficient photoexcitation of organic dyes. Fullerene compounds are semiconductive and their band gaps may be controlled to stay within the range of 0.75-1.9eV, and this justifies a hope that they will serve as solar cells. As for TPV (thermophotovoltaic) conversion, it is under development mainly at NASA (National Aeronautics and Space Administration) as a transportable power source based on heat of combustion. Efforts are also being exerted since 1990 in five European countries to develop TPV systems for small-scale cogeneration. (NEDO)

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

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

    In the 1st (1995) conference of the nations which concluded the Framework Convention on Climate Change, decided on was a trial implementation of an action implemented jointly (AIJ) project with developing countries on the voluntary basis. In the Asia region, emission of greenhouse effect gas is remarkably increasing in accordance with rapid development of economy, and it is important to appropriately support through this project both economic development and energy demand in Asia. Taking the circumstance into consideration, the survey was conducted to contribute to activating the AIJ Japan Program. As the AIJ of leading developed countries, recognized were 25 (U.S.), 6 (Holland), 8 (Germany), 2 (Norway) projects. As to the AIJ in Southeast Asia, China and India, Indonesia is actively participating in the project, but others less actively. Concerning the project needs in every country, heightening of power plant efficiency, enhancement of efficiency in the transportation sector, new energy utilization, recovery of methane gas, etc. acquire a priority. 21 figs., 31 tabs.

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

    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.

    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.

    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.

    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)

    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.

    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)

    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)

    The paper reported the energy situation in Thailand, the present and future status of coal supply/demand, the present situation of environmental policy and air pollution prevention policy and problems concerning coal and the measures for solution, and a possibility of Japan`s cooperation. In Thailand, the total coal supply amount in 1992 is 16.079 million tons, which is 9.1% of all the primary energy supply amount. The country produces only a few amount of anthracite and subbituminous coal beside brown coal. The domestic coal equals brown coal, the production of which was 15.335 million tons in 1992, 13.9% of all the primary energy demand. Concerning brown coal, 79.7% of all the brown coal supply are for electric power use, and others for industrial use such as the cement industry. The remaining reserve in developed areas is 151.4 billion tons, and the proven reserve in undeveloped areas 756 million tons. The demand for import coal was 11.25 million tons in 1996, and is expected to be 201.73 million tons in 2000. The paper pointed out some problems arising from coal production and spread of coal utilization, and described measures to solve the problems and fields where there are possibilities of Japan`s cooperation. 36 refs., 44 figs., 73 tabs.

    It is thought that environmental prevention technologies related to boilers which are the largest coal use field in China have been almost all made model projects till now. Further, coal or coke is used in various industrial furnaces except boilers in every industrial sector in China. The amount of coal use there is large next to that in boilers, which is a cause of the country`s serious air pollution. Accordingly, an investigation was commenced in fiscal 1997 aiming at grasping the actual state of environmental pollution caused by various coal related industrial furnaces in China and studying the environmental improvement. This time, various industrial furnaces were examined in chemical and iron/steel industries. It could be inferred that both industries made efforts to enhance and rationalize production activities and then give consideration also to the environmental prevention. Generally, however, most plants still have old-fashioned production facilities, while the facilities are being modernized little by little. It was found that in China productivity was lower than Japan and the environmental pollution was in a serious condition. 16 refs., 28 figs., 69 tabs.

    The systems in American and European countries for technological development of welfare-related equipment and tools are surveyed and analyzed, with the objectives to draw proposals for establishing the systems which help smooth spread of the research/development results. It is necessary, in selecting the research themes, to well balance the supports for research and development based on the ideas and initiatives by the researchers with those for the publicly invited themes in which the government narrows down the politically important items. For exchanging researchers, the program should help exchange researchers routinely, to match the needs and seeds. It is necessary for the research and development programs promoted by the government for welfare-related equipment to quantitatively grasp the characteristics of various body functions and deterioration of these functions by aging, and to encourage the new participants by providing them with the databases. For promotion of spreading the R and D results, it is necessary to develop laws and regulations which help reduce expenses of the individual disabled and aged, and promote purchase of equipment through insurance, like ADA and rehabilitation-related laws adopted by USA.

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

    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.

    A geology/alteration zone investigation and gravitational probing were carried out, with the results summarized, for the purpose of elucidating the structure of geothermal reservoir structure in the Kuwanosawa area. The investigation was implemented in the southeast part of Akita prefecture including Yuzawa city and Ogachimachi during the period between June 9 and August 31, 1999. The results were as follows. The geology of the investigation area consists of granite, as the base rock, and the covering Doroyu layer, Minasegawa layer, Sanzugawa layer and intrusive rocks in the Neo Tertiary system as well as Kabutosan layer and volcanic rocks in the Quaternary system. No wide area alteration zone existed, while vein-like alterations and hydrothermal veins along cracks were recognized, with the fluid inclusion homogenizing temperature showing 240-260 degrees C, which presumably indicates the existence of local hydrothermal activity until comparatively recently. The geothermal structure of the subject area is very likely dependent on thermal conduction from a deep thermal source existing in the Wasabizawa district. In the underground depth, it is inferred that a hydrothermal system is formed in the NW fault structure, lower part of cracks accompanying NS hydrothermal vein, and in the NNW/NE structures inferable from the gravitational probing.

    The survey was conducted based on 'Scope of work for detailed coal exploration in the Pondok Labu East area of East Kalimantan Province, Kalimantan, Indonesia' concluded on June 16, 1995 between NEDO and P.T. Tanito Harum which owns the mining right. This is a BIP survey report. The strike/dip read from the isobath diagram drawn from the result of the boring little agreed with the stratification in the BIP survey. The BIP stratification is greater in strike and dip than in depth. The latter possibly includes false beds and surfaces cut-off/separated by channel, but roughly speaking the structure becomes such a structure as in the isobath diagram. It suggests that there is local undulation everywhere. Judging from the appearance frequency of open type cracks and the size of hole, there are no problems of the crack type decline at frequency of less than one per 5m at the time of drilling mine roadway. The state of upper/lower basement was not good. Refer to the paper (JN9940854). (NEDO)

    It was intended to reduce the thermal loads of solar-pumped solid state lasers (highly densified solar light is irradiated directly onto a laser medium to cause excitation. No electric power is required for the excitation.). For this purpose, experiments were performed by using a selective permeation film. Solar light includes wavelengths not effective for excitation, which causes heat generation and thermal loads such as lens heating effect and thermal stress compounded refraction, degrading the laser beam quality. The Nd:YAG was used as a laser medium, and a multi-layered film (composed of SiO2 and TiO2) which cuts wavelength below 500 nm as a selective permeation film to cut light having wavelengths not required for excitation. A laser transmitting experiment revealed that the slope efficiency is improved by 27% as compared to not using the film. Beam fluctuation was improved to 45%. Using the selective permeation film has realized more efficient conversion of the solar light into a beam with better quality. The results for calculation of heat lens effect by using temperature distribution simulation showed good agreement with experimental values. Using the selective permeation film can suppress the maximum temperature of a laser rod to 68%, as well as the thermal stress. 9 figs., 2 tabs.

    The photovoltaic AC fusion converter (PVAC), of which cost reduction of the total system is possible, was developed. PVAC controls the supply of commercial power by preferentially supplying photovoltaic power to loads for realization of energy conservation. Further, setting the maximum output of solar cell less than the rated load, the system was made the one with no need of storage batteries. This system was realized in a hybrid of the conventional rectification technology and the stand-alone maximum power point tracking photovoltaic system technology. The solar cell input efficiency had been measured as 84% at maximum. Main losses are consumption power of power source, switching loss of inverter, and continuity loss of diode. Ninety-seven percent of the commercial power input efficiency was obtained. Main losses are consumption power of power source, continuity loss of diode bridge, and resistance loss of smoothing reactor. The effect of energy conservation by the use of PVAC was also admitted. 6 refs., 7 figs.

This fiscal year introduced the new project of researching and developing the poly-crystal silicon-based thin film solar cells. Discussions were given on designing the solar cells, including setting of thickness of an active layer required to improve efficiency of the silicon-based thin film solar cells, the light confining technology, and surface passivation. Comparisons and discussions were given on the new amorphous/poly-crystal silicon thin film manufacturing method and the conventional plasma CVD process. A research development program was introduced for a super laboratory to aid establishing the practical application technology for the silicon-based thin film solar cells. Chalcopyrite compounds including CuInSe2, and CdTe have not shown deterioration even in a long-term outdoor exposure test, hence they are noted as materials for high-efficiency solar cells and studied actively. Although still small in area, the net conversion efficiency was found in the order of 17%. Technological development has started to search mass production processes and commercialization possibility in the future. (NEDO)

    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)

    A 'Sub-committee for investigation of crystalline compound semiconductor solar cells' was established with the participation of experts from the industrial, bureaucratic, and academic circles to support the manufacture of ultrahigh-efficiency crystalline compound solar cells, and a survey was conducted about technical trends relating to III-V group compound solar cells. In the study of the trends and tasks of the state of the art technology, it is stated that the III-V group compound semiconductor multi-junction solar cell was steadily improving in efficiency, that the InGaP/GaAs 2-junction cell on a Ge substrate and InGaP/GaAs/Ge 3-junction cell in particular were moving toward mass production, and that the target for the 4-junction cell to achieve was 40% or higher in efficiency. For cost reduction, investigations were made into the heteroepitaxial technology, dimensional enlargement, mass production, raw material cost reduction, feasibility of the polycrystalline thin-film technology, light concentration, etc. For efficiency improvement, boundary layer control, structure designs, etc., were studied. Investigations were also conducted into nitride semiconductors, superlattice construction, etc., which related to new materials for thin films. TPV (thermophotovoltaic) power, etc., were reviewed for their practical application. (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)

    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.

    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.

    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.

    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 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 evaluation and study of reservoirs and the amount of resources, a reservoir simulation is conducted to grasp the characteristics of reservoirs and the amount of resources. For this purpose, the origin and history of the Kakkonda geothermal field are studied, with special attention paid to the origin of the difference in temperature between the shallow-seated and deep-seated reservoirs, the geometry of granite at Kakkonda, the region of recharge of meteoric water, the distribution of saline concentration in the natural state and the cause of the occurrence, the amount of supply of fluids and heat from the depth to the reservoirs, etc. In the evaluation and study of the economic effectiveness of the exploitation of deep-seated geothermal resources, it is learned that, if a 50MW geothermal power station is to be built at a deep level (drilled depth of 3000m on the average) with a rate of 50% attained in drilling, the steam amount required at such a deep level (presumed to be 75t/h) will be more than twice that required at a shallow level (presumed to be 35/h).

In fiscal 1997, a fumarolic gas test is conducted at the deep-seated geothermal well WD-1b which was drilled in the preceding fiscal year. In the test, chemical and isotopic characteristics are compared between the fluids of the WD-1b and the other existing deep-seated wells, and it is found that the fluids from the WD1b originates in surface water just like the fluids from the others and that the constitution of its gas is not greatly affected by magmatic fluids. A PTS (Pressure, Temperature, Spinner flowmeter) logging is performed to observe conditions in the well with the fluids being discharged and to know the inflow point and rate the fumarolic fluids, and the result is utilized to presume the 3-dimensional stress in the vicinity of the WD-1. An isotopic measurement of water included in the fluids is conducted to examine the origin of the geothermal fluids, constant observation and analysis of micro-earthquakes are carried out, and the fluid flow and fluid hydraulic characteristics are also studied.

    For this survey, the latest technology trends relating to microbial functions are summarized to recover and effectively utilize CO2, typical greenhouse effect gas, using microbial functions. Systematic survey and analysis are conducted concerning the microorganisms useful for fixing CO2, CO2 uptake mechanism during the microbial reactions, utilization methods of solar light and useful energy sources except solar light, highly efficient production of useful materials, and usage of produced useful materials. Research has concentrated on use of biological activities for this purpose through design of bioreactors using microorganisms (bacteria and microalgae) for efficient CO2 fixation. For the process to have net CO2 fixation as assessed by its life cycle and to make the process economically feasible, it is essential not only to fix CO2 merely in the form of biomass but in addition to convert it to useful materials by the catalytic activities of the organisms. Three categories were set for the survey, i.e., microorganisms with CO2 fixation ability, available energy for CO2 fixation, and target CO2 fixation products. 169 refs., 49 figs., 14 tabs.

    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.

    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)

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.

    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)

    Russia was selected as a candidate for the joint project implementation based on COP3, and coal fired thermal power plants in the country were surveyed. From among power plants having generation capacity of 200 GW, 600 thermal power plants account for 70%. Two-third of them are using natural gas as fuel, with the remaining plants using coal, which are noticeably overaged, having facility renewal as a pressing problem. Therefore, they can be the good targets for reducing carbon dioxide emission by modernizing the facilities. Promising projects with large cost effect of CO2 reduction were extracted in the Far Eastern and Siberian regions, where weight of coal fired thermal power plants is high. These projects include five plants including Amursk No. 1 and Kabarovsk No. 1 in the Far Eastern region, and five plants including Irkutsk Nos. 6, 10 and 11 in the Siberian region. From among 48 projects proposed to Japan by RAOEES 'ROSSII' in 1998, nine projects were surveyed individually as the objects of case study.

    The paper surveyed the preparation of the coal transportation infrastructure, status of its running, economical efficiency, etc. in terms mainly of the trend of coal production/consumption in China, and coal railroad/water transportation and electric power transportation by mine-mouth power generation. From the survey, the following conclusions were obtained. As to the coal which China uses as a main energy for maintaining the present high economic growth as targeted, there will remain the coal transportation problem between production site (north and west) and consumption site (east and south) still in the future (in 2000 and 2010). China is now facing with a big turning point in a socioeconomic aspect. The advancing opening market policy brought steep rises in energy prices such as coal and electric power, which is affecting various fields. Further, the energy related laws, which were unprepared, are abruptly being prepared, and the environment for the introduction of foreign investment, which is expected to be accelerated, is being prepared. In the future, attention should be paid to environmental problems such as air pollution, acid rain and global warming. 48 figs., 96 tabs.

    Research was made on joint implementation (JI) for preventing global climate changes in China. Since such the stove and furnace consume a large amount of energy, their improvement and energy saving are important for integrated iron plants. Maanshan iron plant was selected for the research. All the furnaces were manually operated without combustion control systems, and oxygen meters for exhaust gas frequently troubled. As measures for the stoves, operation at a proper air fuel ratio, improvement of over heat storage combustion, and dust cleaning for waste heat recovery gas heaters were proposed. For the furnaces, a proper oxygen content at the end of furnaces (reduction of invasion air) was proposed to improve exhaust gas loss up to that in Japan. For this target, reinforced instrument management and standardized combustion control are essential. JI of software improvement for operation and management can reduce annual greenhouse effect gas emission to 45,900t and 6,300t in carbon equivalent for the stove and furnace, respectively. CO2 reduction is also estimated to be 1,173,000t and 205,000t in China of 107,570,000t in raw steel production, respectively. 28 figs., 32 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.

    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)

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.

    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.

    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)

    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)

    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)

    As an energy conservation method for a model building, the following eight methods were selected and trially calculated of the effects. 1) adoption of high efficient illumination apparatus, 2) introduction of an illuminance control system, 3) cooling water secondary pump with invertor, 4) ventilation control for parking lots, 5) heightening of the established temperature, 6) improvement of the 24-hour run chiller, 7) elevator with invertor, and 8) introduction of the photovoltaic power generation. As a result, it was found out that energy was totally reduced by about 3,837.4 MWh/yr or 25.6%. If viewed from the amount of reduction in greenhouse gas, the amount of CO2 emitted from office buildings, approximately 0.22 million t-C/yr, decreases to approximately 0.16 million t-C/yr. Further, approximately 0.93 million t-C/yr, the amount of CO2 emitted from commercial use facilities such as office buildings, department stores and hotels is reduced to about 0.69 million t-C/yr, thanks to the effect of the project on energy saving buildings, which made a CO2 reduction by approximately 0.24 million t-C/yr possible. Validity of the project on energy conservation in Indonesia was confirmed. 2 refs., 55 figs., 38 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.

    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)

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

    In energy utilization in the 'Kawasaki Zero Emission Industrial Complex', optimal regional heat supply systems were discussed. The discussion was made from the viewpoints of introduction of saving-type energies, new energies and renewable energies, and environment preservation performance. The coastal area in the Kawasaki ward is planned of developing an industrial complex with an area of 8.4 ha for operation of about twenty companies. In the assumption of heat demand, four companies only were taken up as the object of the discussion, who utilize heat supply from steam as process heat source for their factories. The total heat demand quantity and heat demand pattern used for the discussion were assumed by hearing and actual record submitted from each company. Optimal systems were discussed on heat supply systems utilizing steam produced by steel mills, with the discussion made on waste heat recovered steam in processes and steam extracted from thermal electric power plants in the steel mills. As a result of the discussion, heat supply utilizing the steel mill steam was found capable of being provided with much lower price level as the estimated unit price than general direct steam supply, leading to a judgement that the system has business feasibility.

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

    Solar battery arrays are installed at different tilt angles for actual measurement in an experiment conducted by TEPCO (Tokyo Electric Power Company, Inc.) Research and Development Center for the examination of their power generation characteristics. Arrays of polycrystalline silicon solar battery modules are positioned facing a direction +7 degrees swung from the south on the Center rooftop and verandah, and they are installed at tilt angles of 0, 30, 60, and 90 degrees. An analysis of system characteristics is conducted, and findings mentioned below are obtained. In fiscal 1996, the highest utilization factor of a yearly average of 11.3% is attained with the ones tilted at 30 degrees. As for the utilization factors at the other angles, they are 10.2% at 60 degrees, 8.8% at 0 degrees, and 8.0% at 90 degrees. The integrated design coefficient remains approximately constant irrespective of the different tilt angles of 0, 30, and 60 degrees. The overall design coefficient of the 90 degree-tilted array installed on the verandah is found to be 0.75, which is higher than those exhibited by the others. Appropriate routes of wirings for modules should be worked out to avoid the ill effect of the shadows of steel towers. 2 refs., 11 figs.

    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.

    For the purpose of spreading/promoting circulating fluidized bed boilers in China, survey was conducted on the confirmation of effectiveness of implementation of the model project on spread type circulating fluidized bed boilers and the appropriateness of the sites proposed for implementation. As to the model of spread type 35t/h-CFB boilers, local products are more integrated into it, taking cost reduction of equipment and secure performance/quality into consideration, and the wider-ranging technical guidance/transfer are conducted also in design/production. In China, where environmental regulations are not strict, and there are many restrictions on funds, the size of the initial investment is an important element for selection of type. Further, the market is very big, about 200 units/year. It is highly possible to realize the competitive cost level by the quantity production effect by increasing local production. Two companies, Southeast Electrochemical Co. and Fujian Prime Pharmaceutical Group Co., which were proposed as sites are financially good and are achieving substantial results. Both companies are located in the urban area, and therefore, environmental measures should urgently be taken, and PR activities for spread are highly effective. It was confirmed that the companies were fully appropriate as sites proposed for the spread type model project. (NEDO)

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)

    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)

    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.

    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.

    Cuttings from bores N11-TD-2 and N11-TD-3 drilled for the purpose of confirming the existence of geothermal resources in the Tsujinodake area were examined and tested, and the results of temperature logging, electrical logging, and water injection tests carried out during the structural boring work were analyzed. Activities were conducted in the four fields of (1) test boring work, (2) survey and measurement, (3) core cutting examination, and (4) comprehensive analysis. In bore N11-TD-2 positioned in the northern part of Tsujinodake, a sharp temperature rise was detected in the clay converted alteration zone between 200m above sea level and 200m below sea level. A high temperature of 215 degrees C was recorded at 200m below sea level, and it was found that high temperature geothermal water was in reserve at the bottom of the clay converted alteration zone between 100m above sea level and 200m below sea level. In bore N11-TD-3 in the southern wall of the Ata caldera, a convection type low temperature profile was observed at a shallow level and low temperature convection of underground water was detected there.

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

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

    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.

    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 fiscal 1998 geothermal development promotion survey in Akinomiya area, this test was carried out to obtain the fumarolic gas characteristics and fluid properties of N9-AY-3 test well by air reaction method. Blowout hot water was reinjected to N8-AY-1 test well drilled in fiscal 1996 to confirm its reinjection capacity. The fumarolic gas test result showed a steam volume of 35.0t/h and hot water volume of 160.8t/h (wellhead pressure equivalent) at a wellhead secondary valve opening of 33.7% and wellhead pressure of 15.3kg/cm{sup 2}G. The whole hot water volume of 30,214m{sup 3} is equivalent to nearly 320 times more than a well volume. Hot water showed pH7.7-8.6, an electric conductivity of 3,960-7,070{mu}S/cm, and chlorine ion concentration of 1,050 mg/l. Alkalescent Na-Cl system hot water showed a geochemical temperature of 283 degreesC. A steam gas concentration including CO{sub 2} as main component was 0.12-0.19vol%. Blowout hot water was continuously reinjected into N8-AY-1 well from a pit by pump to confirm its reinjection capacity. The reinjection capacity of hot water in fumarolic gas was 110t/h without any problem. (NEDO)

    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)

    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)

    Surveys were performed on the institutional aspects of establishment and operation of grid interconnection guidelines in the countries advanced in introduction of discrete power supply systems, namely, England, Ireland, Italy and the United States, as well as on the simulation technologies to realize them technically. In England, the power transmission systems (controller: NGO) and the power distribution systems (controller: PES) are separated, to which grid interconnection operating regulations are provided respectively. Single operation of generators connected to the power distribution system is not permitted substantially. In Ireland, the power transmission and distribution functions are separated, but are in the transition stage. Interconnection, if requested, cannot be rejected except for a case that the interconnection is impossible. Italy has the condition similar to that in Ireland, where no small generators are not permitted of independent operation. America has not unified the operating regulations for grid interconnection, and has apprehension in the independent operation, but no countermeasures have been given. In the simulation technologies, surveys were made on PSS/E, EUROSTAG, and SICRE. The PSS/E is the standard software in America for the current and stability analysis. (NEDO)

    While the introduction and adaptation of the Longwall excavation technology were carried forward for coal producing countries in the Pacific region, U.S.A. information was collected by making tours of coal mines in the West and Washington/Colorado/Utah States, with the intention of ascertaining technological trend so as to carry out efficient technological transfer, and for the purpose of replenishing the contents and contributing to the smooth implementation of the engineer exchange project in 'coal mine technological field'. The coal reserves are 400 billion tons, with 840 million tons produced and with 80 million tons exported; not less than 56% of the U.S. domestic electricity rests on coal. Production by open-pit mining is the majority while the output by underground mining is 38%; the Longwall method has increased as a digging method, taking 18% of all digging output. The productivity is 4.24 ton/person per day and ranks as the world highest. The coal mining technological trend in the U.S. can be summarized as follows. The coal mining output in the West is increasing, with the number of mines decreasing, so that the output per mine is increasing. With the output ratio by open-pit mining increasing, the digging method in the mine is being changed to the Longwall. (NEDO)

    A comparative study of the cost effectiveness in improvement of emission gas was made between the diesel particulate filter (DPF) which is studied as measures against toxic emission gas from the vehicles already sold and the compressed natural gas (CNG) vehicle which has a large number of spread among clean energy vehicles. In the trial calculation, 18 cases were set up using measures by year against diesel car emission gas, use period and annual running distance as valuables. As a result of the study, the following conclusions were obtained. At the present time, when the vehicle price dropped approximately 40% from that at the beginning of the introduction, the cost effectiveness of CNG vehicle is larger than that of diesel car with DPF. Since the unit price of natural gas is comparatively higher than that of light oil, the longer the annual running distance is, the smaller the cost effectiveness of CNG vehicle is than that of diesel car with DPF. The durability period of DPF is considered not so long, and therefore, the longer the use period is, the larger the cost effectiveness of CNG vehicle is than that of diesel car with DPF. (NEDO)

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

    A survey was made to study possibilities of Japan`s cooperation in tackling energy/environment problems in Asian countries. In 1995 the GNP growth rate was 2.6% in the world, while it was 7.9% in Asia showing a rapid growth. With the accelerating industrialization and urbanization, energy demand is now over three times as much as that in the 1980s. This means increases in waste and environmental pollution. Especially, the use of firewood in non-electrified areas is a serious problem the same as the slash-and-burn farming and deforestation. Also relating to the production of electric power, it is inevitable to choose hydroelectric power and renewable energy in addition to fossil fuels. Therefore, the necessity is heightening of various technologies for it and environmental protection technologies such as coal cleaning. Local areas, where the population density is extremely low and the electrification cost is high, became victims of elecrification. There the power system should be shifted from the central supply system to the local distributed one. For it, it is necessary to recognize an importance of the distributed type renewable energy which is friendly to the environment. The paper outlined the state of each country and energy by policy and environment. 10 figs., 83 tabs.

    This paper reports the result obtained during fiscal 1994 on research on interface of amorphous silicon for solar cells. In research on amorphous solar cells using ZnO for transparent electrically conductive films, considerations were given on a growth mechanism of a ZnO film using the MOCVD process. It was made clear that the ZnO film grows with Zn(OH)2 working as a film forming species. It was also shown that the larger the ZnO particle size is, the more the solar cell efficiency is improved. Furthermore, theoretical elucidation was made on effects of rear face of an interface on cell characteristics, and experimental discussions were given subsequently. In research on solar cells using hydrogen diluted `i` layers, delta-doped solar cells were fabricated based on basic data obtained in the previous fiscal year, and the hydrogen dilution effect was evaluated from the cell characteristics. When the hydrogen dilution ratio is increased from zero to one, the conversion efficiency has improved from 12.2% to 12.6%. In addition, experiments and discussions were given on solar cells fabricated by using SiH2Cl2. 9 figs.

    Inquiries are made to consumers (monitors) who own a photovoltaic power generation system at their houses, and their replies are analyzed for isolating the factors involving the purchase of this domestic power generating system. A large part of the monitors are 40-50 years old males in the relatively high income bracket. They are very interested in problems of global environments, resources, and energy, and are inclined to assume value-consciousness and life-style which encourage them to love health and nature, participation in social functions, and decision-making. The need for the protection of global environments occupies more than 90% of the reasons for their adoption of photovoltaic power generation. The monitors strongly feel, however, that they paid very much for the apparatus although they were granted some subsidies. As for motives for their acquisition of the system, their answers are categorized into four groups according to their responses as to whether (or not) they expect economic merits though dependent on future development and whether (or not) they accept the current energy policies. The result shows that some monitors think like average citizens. 17 refs., 22 figs., 11 tabs.

    In order to investigate characteristics of photovoltaic (PV)/thermal hybrid collectors (PV/T{sub s}) operating under varying conditions, energy equilibrium equations have been developed for numerical calculation, and the calculated results were compared with the observed ones. The calculated characteristics are close to the observed ones, both for photoelectric conversion and heat collecting characteristics, demonstrating validity of these energy equations. It is found, by comparing characteristics of PV/T{sub A} (covered with glass) with those of PV/T{sub B} (not covered with glass), that these characteristics are greatly affected by glass cover. Maximum overall excergy levels attained are 13.29% with PV/T{sub A} and 11.48% with PV/T{sub B} under the conditions of solar radiation intensity H: 800W/m{sup 2}, ambient temperature: 20degC and wind velocity: 0.5m/s, where flow rates of heat medium are 2.0times10{sup -3} and 4.0times10{sup -3}kg/s, respectively. Thus, the PV/T{sub A} system has a higher maximum excergy efficiency than the PV/T{sub B} system. The PV/T{sub A} gives water of higher temperature, demonstrating that covering the system with glass increases maximum excergy efficiency and optimum temperature. 6 refs., 5 figs., 2 tabs.

    A 20kW system is installed on the rooftop of a newly constructed building accommodating a study and training center and citizens` welfare facilities. The system in continuous operation under real loads (lighting, airconditioning) will provide various data useful in introducing further systems in the future and in verifying the effect of system installation cost reduction efforts. Single-crystal solar cells are used, which are located at latitude 35deg8prime north, longitude 137deg4prime east. The arrays are formed into two systems, 18 in series and 7 in parallel, and there are 252 modules. The arrays are inclined at 20deg and, in azimuth, swung 25deg westward from due south. The installation of this system forms a precedent, following which more may be introduced. Located in front of a station on Meitetsu Toyota Line, it advertises itself fully to the passengers getting on and off the train. Now that power consumption fluctuates very much in this district, heavy on Saturdays and Sundays and light in the daytime on weekdays, rare data not often available will be collected from this photovoltaic system. Since consideration space-wise has been fully made, visitors can study the photovoltaic system until they are satisfied, the system thus finding itself under conditions where advertisement can be effectively carried out. 14 figs., 1 tab.

    Contents are reported of the fiscal 1996 field test of a photovoltaic power generation system installed on the roof surfaces of the parking lot of the above-named newspaper company. The system is used to supply power to the lights in the company office and to a light sign tower for local activities promotion (erected jointly by cities and towns in the neighborhood). It is a 10kW plant operating on system interconnection, provided with an array of 9-series/11-parallel configuration facing due south and inclined at an elevation angle of 15deg. It is so designed that solar cell mounts are installed on two roof surfaces so that space will be secured for the parking lot. The above-mentioned LED-aided light sign tower serves the purpose of informing people of photovoltaic power generation technology and the culture, history, and industry of the local communities involved. Basic data have been collected usable for standardizing the design for example of the mount for the establishment of guidelines for reduction in the system construction cost. Data have been also obtained that will help make propositions about the effective utilization of dead space outdoors. Since the system is installed making use of roof surfaces without affecting parking lot capacity, people`s understanding of the technology has been deepened and data of long-term operation following the experimental introduction and troubles have been collected, all these helping encourage the introduction of photovoltaic power generation

    The photovoltaic/wind/diesel generating system that uses a storage battery as auxiliary power has been proposed to supply power from the system to the independent area. In this system, it is important to generate no insufficient power from the viewpoint of effective energy utilization and minimize the fuel consumption of a diesel generator. Authors have proposed the adaptive fuzzy control that changes the shape of the membership function of input variables according to the parameter indicating the system state. However, a parameter was rapidly changed in the conventional method. This badly influences the control. Therefore, the way to determine the parameter that indicates the state of this system was improved. Assume that an input value is set to the average value between a certain point of time and the {Delta}t time as the method for determining a parameter. If the {Delta}t value is lower, the change in a membership function is more effective. As a result, a greater fuel reduction effect was obtained. 4 refs., 8 figs., 1 tab.

    A survey was conducted on the present status of biomass energy in Japan and abroad and the developmental trend of the latest biomass energy technology. Brazil and the U.S. are most advancing in the biomass energy utilization. Brazil uses sugar cane which is plenty in supply as a raw material, and the U.S. does corn which is the surplus crop. Both countries use the conventional ethanol fermentation technology and produce the petroleum substitution liquid fuel which is in greatest need. As to the technology to convert biomass resource into energy, attention has so far been paid to the development of the production process of the liquid fuel. The latest technology for ethanol fermentation using saccharin and starch as raw materials has already been established in Japan, and the energy-saving type alcohol recovery technology has also reached the stage of practical application. Moreover, as to the ethanol conversion technology with cellulose substrate, the development of the saccharification process will be needed in future. 15 figs., 10 tabs.

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

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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)

    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)

    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.

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

    Storage batteries used in household photovoltaic systems must be free of electrolyte leakage and maintenance, and be readily installable in residential houses. Lead-acid batteries that can meet these requirements and have been put into practical use may include the sealed storage batteries. However, these batteries currently in use have drawbacks in life performance and price. Therefore, development is under way on lead-acid batteries for household photovoltaic systems by improving said sealed lead-acid batteries. The targeted batteries should have as long life as passing 3,000 cycles under a condition of 0.1 to 1 CA discharge (at depth of discharge of 50%), energy density of more than 70 Wh per liter, and cost of 12 yen or lower per watt-hour. A prototype battery as the final candidate was fabricated, that uses silica powder as the electrolyte retainer (silica powder filled between plates, and into clearance between plate groups), pasted plates made of expanded metal grids for positive plates, and micro conductive network plates with increased addition amount of carbon to micro active material (PbO{sub 2}) as negative plates. Life performance testes thereon are being performed. This lead-acid battery is estimated to be capable of satisfying the intended performance based on the result of discussions having been made so far. (NEDO)

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

    With relation to the coal of the Philippines, 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/development, the trend of coal import and domestic distribution, the coal utilization trend, and environmental problems, and analyzed the situation of coal utilization/spread by industry including the commercial/residential use. The purpose of the survey is to draw up a master plan for the introduction of the environmentally-friendly coal utilization system. As to the use of environmentally-friendly coal technology which should be adopted to the coal mining industry and commercial/residential sector, cited are the introduction of coal preparation technology and power transmission technology, and the development/spread of briquette as a firewood substituting fuel. In the electric power sector, the problem is the treatment of ash after combustion and the effective use. Relating to the treatment of flue gas, there is no installation at all of desulfurization facilities and denitrification facilities. In the cement industry sector, they wish to return fuel from heavy oil to coal. For it, it is necessary to study dust preventive measures. In the other sectors, coal hasn`t been used very much. An increase in coal demand is not expected also in the future, and big problems concerning coal haven`t occurred. 42 figs., 64 tabs.

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.

    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)

    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)

    Traffic jam and air pollution by automobiles are currently getting severe in the Mexico Metropolitan Area. Trolley buses were introduced for improving the environment more than ten years ago. Vehicles become too old for use, and their energy efficiency is low. In this project, 200 highly energy-efficient trolley buses are introduced to replace old inefficient trolley buses, which results in the improved traffic convenience in the City and enhanced energy efficiency. The new energy-efficient trolley buses are made of energy-efficient control VVVF inverters produced and exported by MELCO (Mitsubishi Electric Corporation), energy-efficient motors by MELMEX (Mitsubishi Electric Corporation, Mexico), and bodies by MASA which is a major manufacturer of bus bodies. The objective of this research is to analyze the background of introduction of new energy-efficient trolley buses and the effects of the present project. The results of analysis are going to be utilized for future promotion of the Joint Implementation and Clean Development Mechanism. 30 refs., 30 figs., 24 tabs.

    This investigation elucidated the possible existence of geothermal reservoir layer in the subject area by studying and analyzing the hot-spring gasses of Musadake. The Musadake area is the one extending over Shibetu-cho and Nakashibetu-cho, Shibetu district, Hokkaido. The sampling of the hot-spring gasses was carried out at three natural gusher sites and one hot spring well site. The gasses in the Kawakita hot spring is most affected by volcanic gasses. The origin of the volcanic gasses is a magmatic gas of andesite nature the {sup 3}He/{sup 4}He ratio of which is 8X10{sup -6} or about. As a result of the analysis, the hot-spring water is Na-Cl type, high salt concentrated, and 200 degrees C in temperature; from the result of a gas geochemical thermometer, it is estimated to be not less than 250 degrees C. In the tectonic viewpoint, the depth hot water is derived from the meteorite water that flows in through a bent zone incident to the Musadake-Shitabanupuri mountain fault and from the fossil sea water that exists in the underground depth; the depth hot water is formed by conduction heat from a magma reservoir that formed Musadake and by volcanic ejecta. This depth hot water rises along Kawakita south, Urappu River fault, etc., mixing with the meteorite water and forming the shallow reservoir layer. (NEDO)

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

    The composites consisting of {alpha}-quartz crystallites and amorphous SiO{sub 2} were prepared by HIP technique, imitating the structure of natural agate. In the previous study, the K{sub IC} of the composite prepared from the mixed powder of crystallites and amorphous SiO{sub 2} was comparable to that of the natural agate (0.56MN/m{sup 1.5}). In this study, to increase the toughness of the composite, (1) the mixture of silica sol and {alpha}-quartz powder and (2) silica sol including nucleation promoter were examined as starting materials respectively. These starting materials were pressed into powder compacts with {phi} 10 multiplied 50mm in size. The Pyrex glass capsule containing the compact was hipped at 800-1,200 degrees C for 0-120 minutes under the pressure of 200 MPa. The K{sub IC} of the composite obtained from the mixture of silica sol and {alpha}-quartz powder was equivalent to that obtained in the previous study, while the maximum K{sub IC} (0.63 MN/m{sup 1.5}) was obtained when PbCl{sub 2} was used as a nucleation promoter. The nucleation promoter having low solubility in water was useful for the homogeneous generation of the crystallites. (author)

    This paper reports the result obtained during fiscal 1994 on research on research on optimization of bandgap in thin film compound solar cells. In research on Cu(InGa)Se2 thin film solar cells by using a gas phase selenide making process, discussions were given on optimizing the following three processes: a process to raise temperature of a precursor film formed at a substrate temperature of about 150{degree}C, a selenide making process to perform annealing at about 500{degree}C, and a temperature reducing process. Good characteristics were obtained when selenium amount in the precursor is about 50%. In a bandgap control viewpoint, it was found that the conversion efficiency decreases rapidly when Ga composition is higher than 50%. A conversion efficiency of 14.9% was obtained to date at the Ga/(In+Ga) ratio of 0.4. In research on Cu(InGa)Se2 thin film solar cells by using a simultaneous deposition method, a conversion efficiency of 13.5% was obtained at a bandgap width of about 1.3 eV during research on manufacturing ZnO/CdS/Cu(InGa)Se2 thin film solar cells by using the simultaneous deposition method. Research has been carried out on manufacturing Cu(InGa)Se2 thin film solar cells using ZnSe interface layers. 8 figs.

    Studies are made about the control of the power conditioner over the maximum power point tracking (MPPT) function in a photovoltaic power generation system. The analysis is conducted by means of computer simulation into the effect of a start/stop function added to the control of MPPT and the effect on the generation of power of the setting of parameters in the start/stop function. The reduction in output power due to difference between the actual operation point and the optimum operation point is evaluated by use of a load matching correction factor. In this simulation, it is assumed that the solar cell array consists of 13 rows in 5 parallel columns, is capable of a normal output of 3.149kW, has a panel tilted at 30 degrees, and faces due south. The power conditioner is assumed to be a system rated at 3kVA, equipped with system interconnection and back flow features. As a result, it is learned that the stop voltage should be set at 180V or lower and the steady voltage near 185.5V for a good result and that there is not much need after all for the start/stop technique. 2 refs., 8 figs., 2 tabs.

    A report was made on the measurement of data and the results of the analysis at 14 sites of photovoltaic power generation facilities operated under system interconnection by Tokyo Electric Power Company. This type of system is provided in 40 sites as of the end of fiscal 1995, generating 479kw. The items measured were the generated electric energy at all 14 sites, and the quantity of solar radiation, outside air temperature, panel temperature, etc., at limited sites; and the capacity of each equipment, azimuth and inclination of the panel were also recorded simultaneously. Hourly values were used for the analysis. Five minute values were utilized, however, in the examination of the cause of lowered output and in the situation recognition of the influence of the shade or the change of weather. The utilization factor of the facilities was in the average 10.8% in fiscal 1994 and 10.7% in fiscal 1995. The factor decreased slightly unless the panel azimuth faced due south. The utilization factor at the panel inclination of 35 degrees and 45 degrees showed both 10.4% through the year making no difference. The system seemed to show no overwhelming possibilities in coping with electric power demand. The reason was that deviation existed for 2 hours or so in the peak and that reliability was low as basic power facilities. However, it was determined that the system be continuously examined in future. 9 figs., 1 tab.

    Studies are under way for the nation-wide buildup of a network of METPV data, new standard meteorological data resembling the HASP data, for the time-based simulation of the output of photovoltaic power generation systems. There is a method of preparing hourly data covering a long period of time for computer processing for the determination of the average hourly power generation level, which, however, will be unrealistic because of the enormity of calculation work involved. Hence: the concept of standardized meteorological data, which involves the specification of typical years after examining the data covering a long period and the preparation of the data of the years for computer processing. In the METPV setup, three types of data are prepared: data for the year of the average insolation, data for the year of insufficient insolation, and data for the year of excess insolation. Next, for each of the twelve months, the year of the average insolation is found. When the twelve pieces of data for the twelve months (of different years) are combined, an artificially constructed year results, with each of the twelve months having the average insolation. A technique has been developed for smoothing the discontinuity between the months. Forty observation spots were built in fiscal 1995, and 150 spots will have been prepared across the country by the end of fiscal 1996. 6 refs., 4 figs.

    The paper studied the working-out of the basic plan on the RPF (refuse paper and plastic fuel) production business in the area mainly including Nagoya city and of the business profitability. RPF is a solid fuel made by grinding, mixing and pressurizing paper and plastics in appropriate sizes. Its shape and calorific value can be adjusted according to the needs. In the Nagoya area, the demand for RPF is more than the supply, and therefore a much larger amount of RPF is in need. In Phase 1, business was studied for paper and plastics in the container packing paper waste and business-derived general waste. As a result, the RPF production amount was 21,000 t/y, which is equivalent to the effect of reduction of the same amount of coal. As to the profitability, it was made clear that the business can be profitable if collecting 41,400 yen/ton as the re-commercialization cost. In Phase 2, the design of the facilities was made for the larger-sized commercialization by adding industrial waste plastics to the waste in Phase 1. (NEDO)

    Supposing the case where the geothermal development promotion survey was carried out in promising geothermal areas in Japan, investigational study was conducted on possibilities of introducing the hot spring effect prediction method, improvement of the method, etc. In the survey, adjustment/classification of formation mechanisms of hot spring were made. For each of the formation mechanisms, the mechanisms in case of the geothermal development having effects were studied/summarized. As to how effects are brought about, presumed were the lowering of water level and decrease in discharge amount in accordance with the decreasing pressure and the dilution by increase in mixture of the ground water around the area. Also cited were the vaporization of hot spring aquifers by the increasing rate of vapor inflow, etc. For the introduction of the hot spring effect prediction method to the geothermal development promotion survey, the problem is short supply of various data, and the examination for it was made. Based on the results of the survey, items to be studied in case of introducing the hot spring effect prediction method were selected. Further, the hot spring effect prediction flow in case of introducing surface survey and well survey was made out. (NEDO)

    An electromagnetic surveillance using the simplified MT (magnetotelluric) method was conducted to help clarify the geothermal structure in the western part of the Hakkoda area, Aomori Prefecture. The survey covered approximately 60 km{sup 2,} and involved 38 survey points, 3 magnetic field components, 2 electric field components, not less than 10 measuring frequencies in the range of 0.01-125 Hz, and a measuring time of not less than 2 hours. An analysis was performed, with data previously collected at 60 points added to the data collected at the said 38 points. As the result, the resistivity structure in this area was divided into 3 layers of high-low-high as described from the surface to the depth, and the middle layer was further divided into 3 layers of high-middle-low and the bottom layer into 2 layers of high-low. The result conformed though roughly to the result obtained by the electrical logging carried out in the structure boring. In the geothermal zone including the Sukayu hot spa in the southeastern part of this area and along the Jogakura valley, there exist a complicated resistivity structure attributable to geothermal activities and a number of discontinuous lines of resistivity running in the directions of WNW-ESE and N-S. This enabled an inference that there is a deep-seated geothermal source between Odake and Akamizusawa extending eastward from the said geothermal zone. (NEDO)

    A questionnaire survey was conducted of the actual energy consumption in the business sector (schools, hotels/inns, hospitals, and other service business) in fiscal 1996, and was put together with the survey conducted in the past in order to clarify the structure and trend of energy consumption in the commercial/residential sector. The survey was aimed at making basic data for the development/introduction of the petroleum substituting energy including future new energy. The consumption unit requirement of a school total was 84.9 Mcal/m{sup 2} per year, that of a hotel/inn total was 455.3 Mcal/m{sup 2} per year, and that of a hospital total was 400.2 Mcal/m{sup 2} per year. The energy consumption for business use was summarized. The consumption unit requirement of restaurants was the largest, 622.8 Mcal/m{sup 2} per year, and that of schools was the smallest. In office building business and wholesale/retailing business, electricity is largely used mostly for illumination, power, etc. In restaurants, gas is largely used mostly for its own use including cooking. In schools, energy use for space heating was the largest, but was almost the same as that in office buildings in terms of the amount. 179 figs., 31 tabs.

    Based on the concept of human life engineering database, a study was made to know how to technically make such a database fittable to the old people in the age-advancing society. It was then proposed that the old people`s human life engineering database should be prepared to serve for the development and design of life technology to be applied into the age-advancing society. An executive method of structuring the database was established through the `bathing` and `going out` selected as an action to be casestudied in the daily life of old people. As a result of the study, the proposal was made that the old people`s human body function database should be prepared as a R and D base for the life technology in the aged society. Based on the above proposal, a master plan was mapped out to structure this database with the concrete method studied for putting it into action. At the first investigation stage of the above study, documentation was made through utilizing the existing documentary database. Enterprises were also interviewed for the investigation. Pertaining to the function of old people, about 500 documents were extracted with many vague points not clarified yet. The investigation will restart in the next fiscal year. 4 refs., 38 figs., 30 tabs.

    With an intention to solve environmental problems and energy problems simultaneously in Sumoto City, Hyogo prefecture, surveys have been performed on feasibility of introducing biomass energy in the district. The dairy farming in Sumoto City has a trend of increase in the number of livestocks being fed in individual farms, and increase of milking quantity per livestock (increase of sewage discharge amount), with the increase of excessive excreta amount causing a problem. The Sumoto Dairy Farming Association is experiencing generation of excreta of 156 tons a day, which requires manure handling and disposal of 112 tons a day even after deducting the field dispersion. Discussions on a biogas plant with a capacity of 100 tons a day call for biogas generation amount of 2,500 m{sup 3} a day, electric power generation amount of 4,500 kWh a day, fuel cell size of 100 kW x 2 units, and heat generation amount of 6,000 kWh a day. A total of the estimated project cost amounts to 2,450,000,000 yen, the annual running cost to 65,280,000 yen, and the annual income to 82,000,000 yen. The electric power generation cost is 135 yen per kWh, the heat production cost is 952 yen per liter (converted to kerosene), and the saving amount due to excessive electric power and heat utilization amounted to 10,700,000 yen. The annual amount of CO2 reduction is 1330 tons. (NEDO)

    The purpose of this research is to identify the problems and measures for reduction of GHG emissions by conducting research on the GHG emission trends in the energy-conversion, industry, public and transportation sectors, and policies and regulations. Japan`s total emission of CO2 in FY 1994 was 343 million tons in terms of carbon, and the emission per capita was 2.74 tons. These amounts were 7% increase in total CO2 emissions and 6% increase in the emission per capita compared with those in FY 1990. There were high increases in the public and transportation sectors. This trend is expected to continue in the future. Since more than 90% of CO2 emission is derived from energy origin, the climate change problems mean energy and economic problems. To attain Japan`s goal of the year 2000 with maintaining the appropriate economic growth, it is crucial to accelerate energy-efficiency and introduction of new energy. 19 figs., 28 tabs.

    This paper reports a sea bottom gravity survey conducted with an objective to identify deep underground structure in the vicinity of the epicenter of the Hyogoken-Nanbu Earthquake. The surveyed areas are the whole Osaka Bay area north of the north latitude of 34 degrees and 20 minutes, and the eastern part of the Sea of Harima east of the east longitude of 134 degrees and 40 minutes, excluding the areas difficult of performing measurements. A square lattice with sides each about 2 km was arranged with 408 measurement points. The measurement was carried out by using an observation vessel mounted with a sea bottom gravimeter made by LaCoste and Romberg Corporation, which was lowered down to the sea bottom at the measurement points. Errors in positions and water depths at the gravity measuring points were suppressed to less than 0.002 minutes and 0.1 m, respectively. The measurement data were given necessary corrections by using a unified method applicable also to land areas, and a Bouguer anomaly chart was prepared. Based on the chart, this paper summarizes features in the Bouguer anomaly in the surveyed areas (such as the low-gravity anomaly band extending the central part of the Osaka bay from north-east to south-west, and the gradient structure existing on the Awaji island side). 6 refs., 1 fig.

    Discussed in this paper are the P-wave and S-wave zero-offset VSPs carried out utilizing boreholes located in Nada Ward, Kobe City, and Hokudan-cho, Hyogo Prefecture, as part of the deep layer boring survey following Hanshin Earthquake Disaster. This effort aims at the elucidation of P-wave and S-wave velocity structures, high-precision identification of data obtained by the surface reflection method, and collection of basic data for active faults investigation in the future. Among the velocity structures obtained for various layers, the S-wave velocity structures in particular agree with the stratigraphy excellently and may be utilized in seismic analyses to be conducted in the future. Reflection from geological boundaries is received with precision, providing accurate information about correlation between reflection and geological cross sections. The records will be useful in formulating plans for reflection surveys for instance of the boundary between the Osaka group and Kobe group. Generally speaking, reflection coefficients are large when the reflection is from a boundary where difference is great in elastic wave impedance (mainly difference in velocity). In the case of the boundary between the Kobe group and granite in Awaji Island, however, no strong reflection is found despite the great difference in velocity. This is attributed to the complicated, sharp inclination of the basement rock and to its weathering. 4 refs., 8 figs.

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

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

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

    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)

    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)

    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 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.

    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)

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.

    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)

    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)

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

    In order to control optical properties of TiO2 thin films, the TiO2 films were prepared by the sol-gel method using glycols or their ether derivatives as organic ligands to study the effect of the organic ligands on the refractive indices and crystal phases. Samples were prepared as follows: Organic ligand was added into the ethanol solution of Ti(O-iso-pr) 4, and aqueous nitric acid solution was added after reflux, and sol obtained by subsequent reflux was applied on soda lime glass or silicon wafer substrates, which were baked at 400 to 900 centigrade. Three kinds of ligand such as 2-(2-methoxyethoxy) ethanol were used. Measured items are the film thickness, thermal characteristics, crystal phase and refractive indices of thin films. The key points are as follows: In case of TiO2 thin films on the soda lime glass substrate, the changing pattern of refractive indices by temperature changes with the kind of ligand used and further the peak strength of anatase changes with the kind of ligand used. In case of silicon wafer substrates, the peak strength of anatase and rutile changes with the kind of ligand. The refractive indices and crystal phase can be controlled by properly using the ligand. 7 refs., 11 figs.
