    This survey is designed to analyze, e.g., current status of large-scale wind power generation devices/system technologies and development trends worldwide, and to make predictions about future developments, in an effort to contribute to advancements in new technology for wind power generation systems in Japan. The international R and D cooperation programs promoted by IEA and EU have helped the participants produce a number of good results at lower costs. The European countries have developed the wind power generation industries in each area, promoted by the governmental subsidy policies, and are leading the world. The system is becoming larger, from around an average unit capacity of 250kW in the beginning of the 90's to 600kW now, reducing the cost by the scale merit. The improved computer capacity has made it possible to more easily analyze the complicated rotor aerodynamics, structural dynamics, wind characteristics and other factors related to wind power generation systems. The future R and D directions will include world standards for large-scale wind turbines, advancements in wind farm technologies, offshore wind power generation systems, advancement in design technologies, and new concepts for wind power turbine designs, e.g., floating wind turbine.

    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.

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

    With an objective to prepare a strategic technological development program for solar heat utilization, evaluations and discussions were given on solar heat utilization from the viewpoints of 'utilizing applications', 'demand' and 'possibility of the proliferation thereof'. In the solar heat utilization, the cost rising in approximate proportion with scale of the heat utilization must be considered as one of the predestined conditions. What can be conceived as a means to enhance the economic performance by using engineering approaches would include heat storage, elementary technologies for transportation and the standardization thereof, and the scale economy on the production side in mass production. As a required step in which the series of favorable circulation of standardization to mass production, cost reduction and large quantity proliferation can be induced, it is appropriate to assume household use with high calorie unit price as the target. The household area covers room heating and hot water supply, in which the temperature level is much lower than in industrial use. In this area, a system may be established with a conception to use solar heat as the main heat source, and calorific power by fossil fuel as the supplementary heat source. Solar heat utilization may be considered utilizable in foodstuff factories and school lunch supply centers. (NEDO)

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

    Described herein are the results of the FY1994 research program for investigation for popular type snow melting systems using solar energy. Two types of technologies are proposed to utilize solar energy for snow melting in winter and create comfortable environments. One is combined (active plus passive) type, which transfers solar heat it collects by the whole wall surfaces to an attic to heat it totally, and makes the whole roof as a radiator to melt snow. However, heat radiated from the roof is insufficient to melt all snow on the roof, allowing it to remain to an extent that it works as an insulator. The other is active type, which transfers heat it collects by the collector to the heat storage tank, from which heat is extracted in winter for various purposes, including snow melting. Such a system must store heat for an extended period, for which a highly insulating heat storage tank is proposed to balance capacity of heat storage between seasons and building size.

    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 survey includes the characteristics of small-scale power grids, feasibility studies on introduction of wind turbines in these grids, and statuses of application of wind turbines to isolated islands or the like in the advanced countries, in order to promote introduction of wind power generation systems in isolated islands or the like. It is concluded that small-capacity wind power generation systems can be possibly introduced in the intermediate- to large-scale grids in isolated islands, 1,500kW or larger in capacity, in the Tokyo, Kyushu and Okinawa Electric Power Companies' areas. A scheduled steamer ship for isolated islands can carry up to 10 ton track, and introduction of a small-scale wind turbine is more advantageous viewed from the transportation cost. Some foreign countries have the sites which have achieved a high percentage of grid connection of wind power units by stabilizing wind conditions and connecting them to the main high-voltage grids in different manners from those adopted in Japan. For developing wind turbine bodies, most of the foreign countries surveyed are concentrating their efforts on development and manufacture of large-size units, paying little attention on development of small-size wind turbines for isolated islands. For the future prospects, the promising concepts include adoption of wind turbines small in capacity and easy to transport and assemble, and hybrid systems combined with power storage units. (NEDO)

    Regarding 'high-speed computation systems for technological use' and 'manganese nodule mining systems,' researches are conducted into technological trends from the viewpoint of patent. As for applications for patents involving the Josephson effect device, there are 79 patents disclosed in Japan, with applications from Japan recording a peak in 1977-1978 and those from overseas in 1974-1975. As for important applicants, IBM distinguishes itself among those overseas while, in Japan, the Nippon Telegraph and Telephone Public Corporation occupies 47%, and Fujitsu, Ltd., 34%. In the case of GaAs-based transistors, businesses in Japan occupies as much as 90% of the applications overwhelming overseas businesses occupying less than 10%. As for the patents on manganese nodule mining systems, 183 Japanese patents are pending, with 88 already granted in America. While the main concern in Japan has transferred from the continuous elevator bucket system of 1971-1974 to the fluid dredge system, the fluid dredge system has consistently been occupying the overpowering majority in America.

    Exploration in the Sonai Plain by Sekyu Shigen Kaihatsu Kabushiki Kaisha (Oil Resources Development Corporation) since 1955 is described. The development tasks are made difficult due to the presence of permeability traps. However, 41 out of 65 wells drilled up to late March of 1965 have been successful. Quantities of crude oil and natural gas produced in 1963 were, respectively, 5 and 6 times those of 1958. The Sonai Plain is a relatively new area, and there are still many unknown factors, yet the rate of development has increased greatly. More and deeper wells are expected to be drilled with even better results.

    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.

    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.

    Gas hydrate is a clathrate compound in a gaseous molecule as the host, stable under relatively mild environments. It is deposited in the 600m or deeper sea bottoms to form the gas hydrate deposit and massively occurring in the sea areas around Japan. This deposit has been studied viewed from natural gas resources, causes for natural hazards and contribution to the global warming. This project excavates a well in the deposit, to study possibilities of the technologies for decomposing, fluidizing and lifting the hydrate as the gas source, and for establishing the natural gas transporting/mooring systems in which its characteristics are utilized. The R and D activities are directed to the 4 areas, (1) development of the exploration technologies to determine the deposit sea area, quantity and conditions, (2) development of the stable well-excavation technologies, (3) studies on the effects of gas production on the environments, and development of the system for predicting the effects, (4) and studies on the application systems. The item (3) finds out the transportation/storage system possibly more economical than the current freezing/liquefaction technologies. The item (3) has the development themes of evaluating the geohazards caused by excavation and gas production, and their effects on the ecological systems. (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.

    An examination was made by a model analysis on sensitivity and the like against a resistive anomalous body, in connection with an electromagnetic tomography system with surface earthquake sources and underground receiver arrangements. A resistivity model was of a three-dimensional structure, and built with a 5 ohm{center_dot}m low resistivity anomalous body assembled in a 100 ohm{center_dot}m homogeneous medium. As a result of the examination, it was shown that the size limitation of an analyzable anomalous body was 50{times}50{times}20m at a frequency of 8 to 10kHz and that a system with high precision in a high frequency range was necessary. The examination of effects under a shallow anomalous body revealed, for example, that the fluctuation of a low frequency response was large compared with a deep anomalous body and that, where a second anomalous body existed under it, the effect also appeared with a surface earthquake source positioned in the opposite side from the anomalous body. The examination of effects under the three dimensional structure revealed, for example, that a remarkable change appeared in the data with the change in the inclined angle of the transmission line against the strike of the anomalous body. 4 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.

    In introducing high-temperature superconducting flywheel power storage equipment to an electrical power system, adaptability is examined and evaluated concerning secondary effect that can be expected while a load leveling function is maintained. The 1998 plan is such that the functions and usages other than the load leveling are put in order for such equipment, and that the effect/adaptability in the case of the introduction into the power system is evaluated by means of simulation and literature studies. The high-temperature superconducting flywheel power storage equipment may be used for such purposes as energy adjustment for a short time, system voltage adjustment and emergency power source, other than the load leveling, on the basis of the characteristics that enable high speed control of active/reactive power and storage/release of energy. Enumerated, as the effects obtainable in introducing these uses into the power system, are enhancement in system stability, improvement in voltage stability, improvement in instantaneous voltage drop, maintenance of system frequency, compensation of fluctuating load, countermeasures against power outrage, and output leveling of intermittent power sources, and these effects were examined.

    Described herein are the results of the FY1994 research program for solar/energy-conversion technologies retrofitted to existing buildings. The estimated effects and economic viability of retrofitting technologies show that they bring very high energy-saving effects when applied to heating and hot water supply, which consume a large portion of energy, but relatively low energy-saving effects when applied to cooling, solar walls, glazed balconies and transparent insulators. The study on applicability of these technologies in Japan indicates that the technologies which can recover cost within an average life time are those applied to windows, solar collector systems for hot water supply and heating, and transparent insulators. Although these technologies are low in applicability to cooling viewed from the angle of cost recovery, retrofitted radiation type cooling systems improve not only cooling and energy-saving effects but also comfortableness.

    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)

    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)

    Concerning the above, it is discussed whether such a system is feasible in Japan. A zinc/air cell system requires some special plants for zinc regeneration, etc. It is necessary to build a zinc refining plant and to install dozens of electrode replacing facilities in an area dozens of kilometers in diameter with the plant at the center. For such a system to be functional, there have to be several tens of thousands of automobile users in a limited area. In Japan, so large a number will not be found anywhere even if the appeal is directed to those in the postal service and electric utilities. There will be no economic success in Japan, different from in Germany. As for the economic comparison between a zinc/air cell system and natural gas system, the two will be equivalent to each other as far as the use of the quick filling stations for the natural gas automobiles remains as it is. When the number in consideration is so large as several tens of thousands, however, the natural gas system will turn out to be economically superior to the zinc/air cell system. 19 figs., 29 tabs.

    Solar technology and energy conservation technology (through retrofitting) which can be introduced into existing buildings are evaluated for their effect and economic efficiency. Studied are technologies verified to be technically feasible at the current stage, introducible into existing buildings without major modification, low in introduction cost, and high in energy conservation effect. How retrofitting technology should be in Japan is discussed. In Japan where demand for heat is smaller than in Europe or America and building service life is shorter, conditions to meet for efficient cost recovery are quite severe. Suitable measures to enhance cost recovery include use of multiple panels of low-radiation glass and light modulators for windows and use of collecting technologies such as solar systems for hot water supply and air solar collectors. Use of a transparent insulator is also recommended. Japanese houses demand repair and reconstruction very often, which helps cost recovery. Dependence on locality is extensive, and this causes difference in solar system application. Since it is high in temperature and humidity in summer in Japan, there is a great need for environmental comfort, and therefore not only energy conservation but also comfortable air-conditioning is important.

    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)

    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.

    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.

    This paper summarizes the result of a geothermal resource survey carried out from fiscal 1995 through fiscal 1997 in the Kumaishi Area located in the western center of Oshima Peninsula in the south western part of Hokkaido. The survey for this area was performed with an objective to search the spread of high temperature area continuing from the adjoining Yakumo area where the highest temperature of 233 degrees C has been confirmed in a structural test well (N63-YK-6), to identify high water permeating areas in great depth points underground, and to find possibility of existence of geothermal resources. The survey included geological and alteration zone survey, geochemical survey, gravitation exploration, electromagnetic exploration, drilling and temperature logging of five structural test wells, water injection test, temperature restoration test, core survey and hot water survey. Also performed were environmental effect survey, rock age measurement, alteration age measurement, and fluid inclusion test. As a result of the survey, it was identified that the verified geothermal hot water has been stored in granites with poor water permeability, whose low temperature has not formed convection systems spreading in wide areas despite having been heated, making each system exist in small scale independently. It was estimated that the possibility is low to expect geothermal power generation. (NEDO)

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

    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)

    For the purpose of constructing new home welfare equipment systems of an energy effective use type, an investigational analysis was conducted of characteristics of the structure of houses considered of aged people, characteristics of the use of home welfare equipment, etc. As to the subject on space warming/cooling, it was found that the hour of stay-at-home of the aged tends to be longer, and the hour to be required for warming/cooling is longer, that the aged gradually lose senses regarding the peripheral environmental temperature, and the temperature to be considered should be at warmer/cooler levels, and that they are weak in heat shock, and the space of house where the temperature is uneven should be removed. Further, from the study in each welfare techno-house, possibilities were pointed out of further energy conservation in houses considered of the aged and home welfare equipment systems like the weight reduction of home welfare equipment systems and reduction of stand-by power, high air-tightness/high thermal insulation of houses for the aged, use of waste heat from air conditioners, introduction of solar energy to stand-by power and electrically-driven wheel chairs. 257 figs., 89 tabs.

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

    This paper reports the study results on the standard weather data necessary for simulation of PV power generation systems in fiscal 1994. In the study on the selection criterion of the standard weather data from the viewpoint of PV power generation systems, three typical years are used; a year with average solar radiation, and two years with extremely less and more solar radiation for safe simulation. The standard weather data are arranged for output calculation of PV power generation systems by selecting the most typical year based on long-term observation data. The data to be arranged are as follows; total, direct and scattered solar radiations incident upon a horizontal surface, solar radiation upon a slope surface, sunshine duration, air temperature, wind direction, wind velocity, amount of precipitation, and snow depth. For arrangement of the nationwide standard weather data, estimation of total solar radiation is necessary based on sunshine duration data observed by all weather bureaus. In this study, the estimation model was developed of the total solar radiation integrated with time from rotary pyrheliometer data. 5 figs.

    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. The technical issues and solutions for construction of the next-generation transport systems are analyzed. Fuel cell and ITS are important candidates. Substitution of the next-generation transport system for existing buses showed a CO{sub 2} reduction effect of 3.91 Mton/y in Japan. (NEDO)

    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)

    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.

    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)

    This paper reports the result obtained during fiscal 1994 on a survey to prepare scenario for the diffusion of photovoltaic power generating systems. Introduction target planned with help of a diffusion simulation was verified by calculations using simulation models. The calculations made the following points clear: facility costs and power generation costs for photovoltaic power generation systems, amount of introduced photovoltaic power generation systems, number of facilities introducing photovoltaic power generation systems, policy cost to achieve the target, annual power generation amount, oil substituting effect, carbon dioxide reducing effect, and market sizes. Power generation cost in fiscal 2000 would drop down to 53 yen per kWh in new installation in independent houses and down to 31 yen per kWh in systems used in schools. These reductions are the result of progress in mass production as a result of positively implementing the aiding policies. The required diffusion aiding policies revealed from the simulation results include expansion of subsidy operations for house construction, introduction of the systems into public facilities performed by public organizations, aid to system introduction into private business entities, subsidy to facility investments, and enforcement of power purchase institutions. 3 figs.

    A model analysis was used to investigate sensitivity of a two-dimensional structure on a resistivity anomalous body by using an electromagnetic tomography system. The resistivity model handled a three-dimensional structure. The model was prepared as a pseudo two-dimensional model in which a low resistivity anomalous body with 1 ohm-m was incorporated that has a basic length of 1000 m in the Y-direction in a homogenous medium having 100 ohm-m. As a result of the analysis, the following matters were elucidated: if a low resistivity anomalous body is present in a shallow subsurface, its impact starts appearing from lower frequencies than when the anomalous body exists only at a greater depth; if a high resistivity anomalous body exists, the detection sensitivity is lower than for the low resistivity anomalous body, but the analysis would be possible by using the phase because the phase has made a greater change; the source TxZ shows a change from lower frequencies than for the source TxX, and the amount of change is greater, hence the detection sensitivity on an anomalous body may be said higher with the source TxZ; however, for the anomalous body in shallow subsurface, the source TxX is more effective since it is not subjected to a too great impact at a greater depth. 5 refs., 7 figs.

    With an objective of establishing a practically usable process to manufacture substitution natural gas, discussions have been given on the technical, economical, and developmental problems therein. This paper summarizes the achievements in fiscal 1992. With respect to the possibility of applying the coal SNG to power generation fuel, a power generation system composed of coal SNG, pipeline transportation and natural gas was recognized of having the significance of technological development because of its capability of raising the power plant utilization rate and possibility of being superior in the economic aspect. In the study on enhancement of aqueous solution yield, performance of the ARCH-2 reactor was discussed by the simulation forecast using a mathematical model, whereas the benzene yield was found possible to be raised up to 15% in the carbon conversion rate. As the target of the hydrogasification process to be developed by Japan, based on the study results of the current fiscal year, three points consisted of SNG yield maximization, cooling gas efficiency maximization, and BTV yield maximization were indicated, and it was proposed that a process having flexibility in the product yield should be developed.

    An automotive navigation system was outlined. Features of this system are described below: map display called `Bird View` extending up to the horizon was commercialized; accuracy of determining the vehicle`s present position was realized using new algorithm; and automatic route selection was adopted. Human machine interface of this system also was completely reviewed. `Bird View` was realized by reading plane map data out from CD-ROM and converting them onto the coordinate on the virtual screen in front of the view point. Automatic selection which depends mostly on self-contained navigation adopts the certain way in comparison of the computation position in GPS. To assume vehicle advancing direction, employed were optical fiber gyroscope, geomagnetic sensor, and Karman filter making a good use of advantages of GPS, for the improvement of accuracy. For the automatic distance correction, a function of correcting pulse-distance conversion coefficient was employed, and the free maintenance was realized. 5 figs.

    The international Medical Treatment Symposium and Exhibition were held from July 20 to the end of August, 2000 in Hannover in Germany, in which the Japan's system for supporting low-invasion surgical operations was presented and information was exchanged for the system. A total of 50 to 100 neurosurgeons visited the exhibition, held as part of the symposium, every day from July 21 to 24. The system for supporting low-invasion surgical operations is rated as the most advanced one in the world. It attracted much attention, because a number of attendees applied for operating manipulator. The research trends seen in the symposium point to early diagnosis of diseases, finer surgical operations, low-invasion type operations, use of high-function diagnosis devices for improving operations, real-time imaging, and application of DNA diagnosis to pathological diagnosis, among others. Japan is leading the world in the technological areas of micromachines, robotics, high-vision and diagnosis. The bold researches, e.g., those on artificial visual and hearing systems to be embedded in the head, are pursued more extensively in the overseas countries. (NEDO)

    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)

    This paper proposes an automatic emergency reporting system as an ASV technology for preventing secondary damage. In the event a vehicle is involved in an accident or other emergency situation, this system automatically reports the vehicle`s present position along with information on the vehicle and owner to an operations center via radio signals. This makes it possible to dispatch an ambulance or other emergency vehicle more quickly. A prototype simulation system has been built consisting of a custom designed control unit for in-vehicle use and a personal computer that simulates an operations center. The interface between the control unit and the personal computer is a wireless modem. The navigation system offered in the Cedric was modified for use as the vehicle location sensor and map database of the operations center. In experiments conducted on the system, information was transmitted from the control unit and shown on a digital map display on the personal computer screen in about ten seconds following activation of an emergency signal. 5 figs.

    An investigational study was conducted for the Kirishima region with the aim of contributing to working out future medium- and long-term plans of geothermal development promotion survey, estimation of the developmental resource amount, extraction of technology development subjects effectively connecting to the increase in kW, etc. In the study, literature is collected such as reports of the surveys already made in the Kirishima region and the periphery, the data were re-analyzed and divided into geological structure elements and geological structure elements, and a conceptual model of the geothermal system in the whole Kirishima region was made. As a result, two areas were extracted for which the existence of high temperature geothermal reservoirs is expected. The total resource amount was estimated at 2,785MWe at promising area 1 and at 3,237MWe at promising area 2. With the resource amount density, data likelihood and distribution status of national/quasi-national parks as extraction criteria, 6 out of these promising areas were focused on important areas for survey. Geothermal structure models were made for each of the 6 areas, and the evaluation of the resource amount using evaluation assist tools was carried out. (NEDO)

    The results of surveys conducted in the Noboribetsu region, Hokkaido, in fiscal 1987-1989 are compiled in this report. Conducted in the surveys were a geological/alteration zone survey, geochemical survey, electromagnetic surveillance (simplified magnetotelluric method), electric prospecting (Schlumberger method), electric prospecting (mise-a-la-masse method), heat flow rate survey, structural boring, precision structural boring, environmental exploration well, geothermal water survey, environmental impact survey, and so forth. Conclusions reached on the basis of the survey results are described below. It is supposed that a horizon, positioned in the Osarugawa stratum in the Karls Noboribetsu zone or in a fissure system in the Omagarisawa stratum below the Osarugawa stratum, contains a geothermal reservoir. The hot water at the Noboribetsu hot spring originates in gas or geothermal water separated from the deep-seated geothermal water while that at the Karls hot spring or the like originates in meteoric water built up in higher places. Although an area abundant in geothermal fluids is supposed to exist in the Karls-Noboribetsu zone, yet a section located between the Karls-Noboribetsu zone and the Noboribetsu hot spring area also draws attention as a zone having a potential to store geothermal fluids.

The basic designs of measuring instruments for a 100kwp full-scale system are also examined. In relation with the manufacture, testing, and arrangement of solar cell arrays, a large solar simulator is designed and introduced for the measurement of module photoelectric characteristics. Using this simulator, continuous irradiation is performed by a 1kW/m{sup 2} light beam of a spectral distribution of AM (air mass) 1.5. A CZ (Czochralski) single crystal, EFG (edge defined film bed growth method) ribbon, and a small CdS/CdTe solar cell module are installed, through the use of which operating characteristics are determined for comparative study. A DC control unit is designed and built, composed of a rectifying device for the dissolution of noise that greatly affects measurement for the mini-system, DC-AC-DC converter, and a remote control console.

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

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

    As measures for the spots difficult in metering within a framework to integrally automate the power distribution, a remote reading system was prototypically tested and evaluated in reliability on the actual field. The system methodically selected the signal {prime}s line injection, high frequency wave signal and voltage detection, while the signal frequency, transmission rate and highest transmission output were set at approx. 3.5KHz, 7.5bps and 50dBm, respectively from the test result. The demonstration test on reliability of the system locatively selected a vicinity of high voltage consumer, high harmonic wave-generating consumer, transforming station, etc. The total ratio of success in reception was comparatively high in Kuzuno and Yamazaki areas, but low in Kamojyo and Ichinomiya areas, The badness in reception was caused by the fluctuation in noise and strongness in damping which was influenced by the condenser in the high voltage consumer. The locative relation between the parent and child stations of system, and high voltage consumer being classified into four patters, an application table of remote reading system was prepared by simulation. 14 figs., 6 tabs.

    In order to achieve rationalization in energy use, surveys and studies were performed on structuring new at-home welfare device systems of effective energy utilization type, based on structural characteristics of residential houses arranged with considerations for elderly people, and operation characteristics of at-home welfare device systems. For the 'evaluation of daily, weekly and annual changes in energy use at care-taking sites', measurements were performed on cumulative power during operation standby and momentary power under no load and load in eight care-taking devices such as a care-taking Gatch bed, a motor-driven lift-up cooking table and a home elevator installed in the WTH Shizuoka, by using a house energy measuring device. The measurements verified that large power is consumed during standby operation. In developing the 'at-home welfare device systems that utilize energy more effectively', a solar beam measuring device was used to measure over an extended period of time the power generation amount of a solar beam power generation system installed in the WTH Shizuoka. Evaluation was given on the system as an emergency power supply for an emergency event, and consideration was given on the effectiveness of the system in the Shizuoka district where daily sunlight irradiation lasts long. Development was made on an inexpensive walking training device, on which effectiveness as a waling training device was evaluated by using a position sensor and a force plate. (NEDO)

    The results of surveys conducted in the Hishikari region, Kagoshima Prefecture, in fiscal 1987-1989 are compiled in this report. Conducted were a geological/alteration zone survey, geochemical survey, electric prospecting, electromagnetic surveillance, gravity prospecting, heat flow rate survey, test boring, environmental impact survey, and so forth. The surveys resulted in conclusions mentioned below. According to the underground temperature distribution based on the results of the heat flow rate survey, test boring, and so forth, temperature is low at the western part of the Hishikari region where there is a low gravity anomaly and high in the zone in the ENE-WSW direction where there is a high gravity anomaly. The present ground temperature is lower than the fluid inclusion homogenization temperature by approximately 120-140 degrees C. It is deduced that the geothermal water reservoir lies in the Quatenary volcanic rocks or in a fracture zone that develops in the Shimanto supergroup. It is inferred that the geothermal water producing the hot spring water all originates in meteoric water staying long in the ground. It is also inferred that volcanic gas or the like contributes but a little to the formation of the geothermal system but that the contribution is great of the heat supplied from the magma pool.

    Based on the June 1998 agreement with Indonesia on a comprehensive survey of the Kalimantan coal transportation system, plans for developing transportation infrastructures and coal mines were established, and a survey was carried out to realize efficient coal development and transportation. In proceeding with the future development of the South Kalimantan coal, it was made clear that the domestic Indonesian demand and export demand thereon can be fully expected, and latent supply capability thereto exists sufficiently. However, although the latent supply capability is available, the coal transportation infrastructures are insufficient, hence new construction of railways and coal shipping ports is necessary. The present survey has prepared an LP model for the coal transportation infrastructures, and performed case studies on six coal transportation scenarios composed of potential existing or new roads, waterways, railways and coal shipping ports. It was found promising economically that, for either case of domestic or export supply, Tg. Selatan port shall be newly built in addition to IBT port and NPLCT port, to link the ports by a railway network to be built newly. (NEDO)

    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)

    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.

    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.

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

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

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

    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)

    Described herein are the FY 1998 results of the study on local wind resource prediction model. The local wind resource prediction models developed so far apply the solutions based on the existing linear models (WASP and AVENU) for relatively flat terrain. These models are studied for their applicability limits. The study covers wind direction and speed patterns of the surface wind and upper winds at 3 sites in Hokkaido, Fukushima Pref. and Shizuoka Pref. The surface winds are found to be correlated with the upper winds both for wind direction and wind speed in almost all cases. Next, wind resources simulations are carried out for each of the classified weather patterns using the existing models, and the prediction errors are studied. The results show that the prediction accuracy of the existing linear models is highly dependent on inputs of observed data, and that the accuracy tends to decrease for the situations where the upper and surface wind conditions greatly differ from each other, as in the case of a land and sea breeze of thermal origin. It is also confirmed that prediction accuracy is lower on complex terrain than on flat terrain. (NEDO)

In the survey, the following were conducted for the comprehensive analysis: surface survey such as geology/alteration zone survey, geochemical survey, gravity exploration, electromagnetic exploration and electric exploration, core test by drilling 5 boreholes, test to induce jetting of geothermal fluids, measurement of in-borehole temperature/pressure, survey of geochemical properties of geothermal water. As to the fracture system in this area, the Amemasudake fault and the Amemasuzawa fault are especially important, and it was assumed that these faults had relation to the present geothermal distribution. It is thought that structural conditions of geothermal reservoirs are fractures in basement rocks. As a result of the borehole survey, it was indicated that the center of the high-temperature part with a temperature of 250 degrees C or more was in the boundary zone southeast of this area at a level of 500m below sea level. The scale, which reached about 3km both in east/west and north/south, is almost the same scale as that of the neighboring Toyoha area where great potentiality of the geothermal development is expected.

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

    This paper describes a survey on problems in developing technologies for the global environment issues. Technological development of means to reduce generation of environmental issues and substitutive means for non-generation thereof is being moved forward specifically in the Sunshine Project and the Moonlight Project. The Chemical Technology Research Institute assumes that it has a responsibility to positively contribute to developing a technological system that matches the substance circulation mechanism of the earth from the fields of chemistry. Therefore, the Institute has organized working groups that have been identifying problems from their expertise standpoints and have been extracting study assignments. Subsequent to the Version I, the Version II has been compiled. The Version II takes up the simulation of global warming mechanisms, behavior of gases dissolved in oceans, and possibility of fixing CO2 in oceans.

    In steelmaking plants, the relining work of converters requires plenty of manpower and time. Recently, the number of expert brick workers has decreased, and it has been difficult to get together the necessary number of workers for the converter relining. To solve these problems, a robot system has been developed and realized for the converter relining. The system consists of two intelligent robots and an automatic brick conveying machine. With visual function and flexibly controlled hands, the robot enables to heap up bricks in the same manner as expert workers do. The automatic brick conveying machine consists of roller conveyers and a cage lifter that convey bricks on palettes to the suitable position for the robot to easily handle. This robot system has enabled to save much labor for the converter relining. 8 figs.

    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.

    Feasibility study was conducted on the technology for practical application of a several kW class fuel cell for the people's livelihood, particularly, for residential use. The study was made in six areas consisting of study on the present state of technology, conceptual design of a small fuel cell, survey on a promising market, basic concept of cell for residential use, feasibility study on application and on introduction. There is no record of development of the several kW class; while the fuel cell excels in the efficiency of energy utilization and the environmental conservation, its performance greatly deteriorates by start and stop under the present technology. Accordingly, it is a prerequisite that the equipment is for an electric heat combined type and for system interconnection. Also, while it is proper that the cell is phosphate type and that the fuel is natural gas, an innovation is necessary in the technology for reforming the cell and the fuel. The conceptual design revealed the possibility of a power generation system having a generating efficiency of 32%, exhaust heat recovery rate of 30%, and dimension of 75x65x150 cm. On the basis of a feasibility study on the application to the combination of a house and a beauty parlor, an advantage was recognized in the fuel unit cost of 5 yen/meal and the equipment cost of 200-250 thousand yen/kW, with demand estimated for 2.5 million installations nationwide including 950 thousand in natural gas supply districts.

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

    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)

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)

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

    The paper summed up the results of the geothermal development promotion survey 'Kaminoyu/Santai area' which was carried out at Yakumo town, Yamakoshi county, and Mori town, Kayabe county, Hokkaido, from FY 1990 to FY 1992. In the survey, the following were conducted for the comprehensive analysis: surface survey such as geology/alteration zone survey, geochemical survey and gravity exploration, test to induce jetting of geothermal fluids by drilling 7 boreholes, temperature/pressure log, etc. The geological structure of this area is featured by the uplift structure/caldera structure and the anticline structure. In the wide-area geothermal system, it is thought that the low-temperature seawater permeates underground by mixture with meteoric water, is heated, and forms the deep geothermal water. It is thought that the hot spring water in this area is stored in the hot spring reservoir by mixture with the surface water, and it is gushing. In the area, the region which is regarded as favorable as passage/storage place of geothermal fluid is a region of 1.5km width extending linearly in the E-W direction from the Nigorikawa basin to Kaminoyu. Further, it is thought that fractures were unfavorably developed in the Santai/Kaminoyu area. (NEDO)

    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 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.

    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.

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

    This paper describes surveys on trends in overseas technologies in development plans for geothermal water utilizing power plants. In heat cycles, the binary and two-stage flash cycles were analyzed by using a generalized equation of state, and theses on optimizing working fluid properties and cycle conditions with maximum thermal efficiency were described. Theses that were described include those for criteria to select working fluids and thermal power cycles against the binary cycle using a heat source at 104 to 204 degree C. The binary cycle working fluid was found better in mixed systems than in pure systems as seen from process and economic performance. The paper introduces a heat conductivity experimenting device and data required for designing a heat exchanger. It also describes the Heber geothermal experimental plant to demonstrate reasonability of assumed working media. A fluidized bed type and a shell tube type were applied to heat exchangers at the Raft River 50 MW geothermal power plant for comparison and discussion. Fouling factor was also estimated. A discussion was given on fluidity distribution of a fluidized bed heat exchanger. Design of a heat discharge system is important for geothermal power generation because heat source temperatures are so low that more than 85% of heat that has been taken in is discharged. The paper also describes turbines and other facilities. (NEDO)

    Described herein are the results of the FY1994 research program for chemical refrigeration and cold storage system using solar heat. The study on refrigeration materials are aimed at development of new hydrogen-occluding alloys which show good hydrogenation equilibrium characteristics and reactivity at temperature required for stand-alone refrigeration systems aided by solar heat, and still new hydrogen-occluding alloys operable at refrigeration temperature for lower-temperature systems. For the refrigeration materials capable of producing low-temperature heat of -10{degree}C at a regeneration temperature of 140{degree}C produced by solar heat, a La-Ni-Mn-Al alloy is selected for high-temperature use and a La-Y-Ni-Mn alloy for low-temperature use. The study on technology for refrigeration modules develops high-efficiency heat exchangers for refrigeration and regeneration, compatible with the hydrogen-occluding alloys. It also develops air-and water-cooling techniques for hydrogen-occluding alloys, where air is used as the heat source. The test apparatus is designed, installed and operated, to attain a low temperature of -10{degree}C or lower with a heat source of 140{degree}C and air heat source of 28{degree}C. 7 figs.

    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.

    With an objective of developing wind power generation systems that suit small to medium size islands in Japan, conceptual design was made on a 100-kW class wind mill to satisfy such requirements as no need of large heavy machines, and gust resisting performance. Investigations were performed on sites suitable for demonstration tests thereof. This paper reports the achievements in fiscal 1999. In investigating the site location feasibilities, which took small to medium size islands in Okinawa Prefecture as the discussion objects, environmental investigation, wind condition forecast and investigation, and system linkage investigation were carried out, whereas one point each in three islands were extracted as the promising sites. The system discussion and design called for wind velocity resistance of 80 m/s, system linkage percentage of 40% at maximum, power generation cost of 20 yen per kWh, design life of 20 years, constructability of requiring no large heavy machines, and operation mode of diesel hybrid use. Along with these specifications, conceptual design was performed on the system constituting elements, such as wind mill blades, generators, electric power control devices, and towers. In the blade aerodynamic test, wind tunnel tests were executed by using three types of blade wings. Sample blades were fabricated for the preparation of blade material tests. (NEDO)

    The radio telemeter system was reported which was developed to monitor gas pressures at unfixed terminal points moving along with the progress of gas calorie conversion from coal gas to natural one. The system was composed of a center system and monitor system to monitor integrally terminal pressures, and terminal systems attached to governors at terminal points of each gas supply area on a medium pressure supply network. The data collected by the terminal systems were transmitted to the center system through a wireless communication system. For efficient and error-free transmission, a hagelbarger code was used because of its bit error correct function by calculation, and a noise-free delayed detection method and rapid two-way retry method were also adopted. Packet and polling communication systems were adopted for data transmission, and batch transmission was also adopted where the data stored automatically in the event of a failure are transmitted in a lump at restarting. 1 ref., 6 figs., 2 tabs.

    The heat exchange system in geothermal wells is a system that replaces the air source heat pump and uses underground beds or groundwater as a heat source to heat rooms by collecting underground heat in winter, and cool rooms in summer by operating a heat media circuit in reverse direction through the action of a reverse flow valve to discharge heat underground. This paper describes feasibility investigations on the system including its technical trend for introducing the system technology. Technological and economic discussions were given by classifying the intra-well heat exchange device in its installation direction (horizontal loop type and vertical installation type), underground heat exchange media (antifreeze solution/water cyclic system and direct expansion system), and underground heat transfer (heat conduction system and heat convection system). As a result of discussing each system, it was concluded that the following two systems are promising: A = vertical installation, antifreeze solution/water cyclic and heat conduction system, and B = vertical installation, antifreeze solution/water cyclic and heat convection system. Since the system B was found to have better efficiency and economy among both systems, it is necessary to verify an intra-well heat exchange system and operation methods that suit the system B effectively. 21 refs., 8 tabs.

    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.

    The above-named survey had been scheduled to be conducted in fiscal years 1996-1998 for an approximately 10km{sup 2}-large area of Kokonoe-cho, Kusu-gun, Oita Prefecture. In fiscal 1996, surface surveys were conducted, such as geological and alteration zone surveys, gravity prospecting, and electromagnetic survey. In fiscal 1997, an exploration well (N9-KH-1: depth 2,222.0m) was drilled. Since the maximum temperature in the well was found to be so low as 78.5 degrees C, the survey was given up in the second year. The survey conducted at N9-KH-1 showed that deep-seated and shallow-seated ruptures developed there in the absence of aquicludes, and so it was inferred that it was a recharge area, as predicted by the temperature logging profile, with surface water flowing into the depth. The above showed that there was no deep-seated blind geothermal system which the survey was after. Since it was not likely that the shallow-seated geothermal system located in the southern part of the Mizuwake pass would be found expanding into the area of the current survey, it was decided that the survey not be carried forward to the following fiscal year.

    This paper describes the surveys on information about new energy technology development in fiscal 1978 in the Sunshine Project. The present fiscal year performed the surveys on the United States and France as the main subjects. For the solar energy development in the United States, surveys were made on power generation using solar heat, solar cells, difference in ocean temperatures, satellites, biomass, and solar energy air conditioning systems. Geothermal energy development was also surveyed. For coal energy, surveys were done on coal liquefaction, gasification, high-temperature gas turbines and MHD power generation. The U.S. energy policy has various kinds of cards. For the solar energy development in France, heat conversion and photo-cell conversion systems were surveyed, while the authorities take development promotion measures on solar heat conversion system under the judgement that this is the only contributor to the new energy development. Surveys were performed on trends in biomass as the biological energy conversion means of the solar energy. Geothermal energy is being advanced of development following that for the solar energy. Surveys were made also on power generation systems using wind power, wave power and difference in ocean temperatures.

    This paper describes development of structural materials for municipal refuse incinerators, in particular, high- temperature corrosion-resistant ceramics for inner walls. Unlike boiler tubes of which inner walls are cooled by water or water vapor, refractory for inner walls is subjected to high-temperature flame over 1000degC, corrosive gases such as HCl and SO2. and low-melting point corrosive dust such as chloride, sulfate and oxide under strong corrosive environment. Experiment was made on 14 kinds of ceramics including commercially available oxide system, non-oxide system and refractory system ceramics. Except graphite system ones, every ceramics, in particular, Al2O3, ZrO2, B4C-doped SiC and CVD-SiO showed superior properties. Commercially available ceramics, in particular, non-oxide system ones are very expensive. Since inner wall materials for refuse incinerators are heat-/corrosion-resistant consumption articles, it is suggested that improvement of reasonable oxide system ceramics or conventional SiC system ones is better. 73 refs., 89 figs., 39 tabs.

    The paper grasped the state of coal utilization by coal consumption field, the state of coal physical flow in Vietnam, etc., surveyed/studied a possibility of introducing the environment friendly type coal utilization system, and assessed the possibility. As to energy resources, the north is abundant in hydroelectric and coal (mainly anthracite) resources, and the south in oil and natural gas resources. Coal production in fiscal 1997 is planned to be 10 million tons. Coal preparation technique presently available is only grain size sieving. Accordingly, it is necessary to study for heightening efficiency of facilities and modernizing facilities in accordance with the introduction of the environment friendly type coal utilization technology. During the study, it is possible to propose improvement on coal processing technology (coal preparation technology). Assessment and study are made especially of the coal selection system, fine coal recovery system and waste water treatment system. For the plan on new coal-fired power plants (300MWtimes4), there is left much necessity of proposing studying models considered of the anthracite combustion technology and environmental improvement and of assessing/studying them. 60 figs., 117 tabs.

    Japan plans to reprocess and reutilise the spent nuclear fuel from nuclear power generation. However, the temporary storage of spent fuel is assuming increasing importance as a means of ensuring flexibility in the nuclear fuel cycle. Our investigations of various methods of storage have shown that casks are the most suitable means of storing small quantities of spent fuel of around 500 t, and research and development are in progress to establish dry storage technology for such casks. The soundness of fuel cladding is being investigated. The most important factor in evaluating soundness in storage under inert gas as currently envisaged is creep deformation and rupture, and a number of investigations have been made of the creep behaviour of cladding. The present study was conducted on the basis of existing in-house results in collaboration with Nippon Kakunenryo Kaihatsu KK (Nippon Nuclear Fuel Department Co.), which has hot lab facilities. Tests were run on the creep deformation behaviour of irradiated cladding, and the maximum allowable temperature during dry storage was investigated. (author)

    This paper summarizes the results of investigations in the Mt. Kunbetsu area out of the investigations on promotion of geothermal development having been performed during the period from 1998 to 1999. The investigated area is an area located in the eastern Hokkaido with an area of about 300 km{sup 2}. The wide area investigation has discussed possibilities of existence of geothermal resources mainly from existence of high-temperature anomalies. The investigation has performed the following activities: fluid geochemical investigations on ten spring water sources, three spring gas sources, and five surface water points; gravity exploration at 153 measuring points; electromagnetic exploration at 52 measuring points; excavation of two heat flow rate wells (to depths of 997m and 995m), temperature logging, core cuttings tests, thermal hot water survey; other fluid inclusions tests, rock alteration age measurement; and temperature logging at Ryuun Shiretoko Spa. As a result of the investigations, it was estimated that, as the geothermal system model, the heat source is assumed to exist at a great depth below Mt. Kaibetsu; the spring water and the mineral spring water show diverse spring qualities because of mixing of meteoric water with fossil sea water; the fossil sea water and the meteoric water have been heated by thermal conduction; and the high-temperature zone is not spread to the positions of the investigation wells.

    Superconductive technologies are introduced into electric power devices for attempts of achieving higher stabilization, density and efficiency, as well as size and weight reduction and improvement in performance of the devices. The project has been worked on since fiscal 1998 as part of the New Sunshine Project. Fiscal 1998 being the eleventh year has taken the following subjects as the research promotion policies: establishment of plans targeted at accomplishment of the goals of the project; adequate and reliable implementation of verification of technological assignments; and steady and efficient demonstration tests. Subsequent to the previous year during which site demonstration tests were completed on a low-speed responsive model machine, the site demonstration test has begun on the ultra high-speed responsive model machine as the final stage of the project. The ultra high-speed responsive model machine was coupled with a freezing system and a load synchronizing machine, and different kinds of test were carried out where good results were obtained. Researches were conducted on characteristics improvement and device element technologies aimed at achieving the practical application level by utilizing the respective features of AC metal-based wires and oxide-based wires, where sound results were obtained. Also in an improved freezing system, valuable data were attained as part of establishing the basic technologies for a superconductive power generation system. (NEDO)

    A downsized wireless blasting system has been developed for tunnel construction in the mountainous districts. This system consists of an oscillator, loop antenna, and initiator. The ac magnetic field is generated in the loop antenna using 550 Hz ac generated by the oscillator, to induce the electro motive force between both ends of receiver coil in the initiator. It is stored in the capacitor after rectification, to initiate the detonator by discharging with the firing signal. This system has been developed by downsizing the conventional RCB (remote controlled blasting system) for underwater blasting, and unmanned operation is planned in future. An oscillation frequency, 550 Hz with an actual result has been adopted. The arm length of loop antenna is 3 m, which can be installed in the tunnel. Various receiver initiators were fabricated as a trial. A convex type was adopted due to its excellent receiving performance. The receiving performance was improved by increasing the magnetic induction and decreasing the power loss. After receiving voltage of the receiver initiator was confirmed, field initiation tests were conducted. Initiating and blasting were successfully carried out. 5 refs., 15 figs., 3 tabs.

    The present survey places particular emphasis on the field of PV power generation systems, and intends to collect data on solar cell application products and PV power generation system installation cases, to classify them according to their usage and to compile a collection of case records including photographs. For the data collection, two formats have been adopted. A format for the solar cell-based products includes a picture of the product, and information on solar cell output and commercialization status. Another format for the installation of PV power systems includes a picture of the installation, and information on location, output level, system type, PV module type, owner, and date of installation. The application of solar cells was classified into 14 fields, i.e., consumer appliances, road and traffic, railroad, general industries, housing related, automobiles, agriculture, ocean development, disaster prevention and safety, amenity, developing countries, buildings, public facilities, and environment. A total of 241 valid cases have been collected. Overseas products and installation cases are often characterized by new applications and innovative design, and contain a lot of useful suggestions for promoting the spread of PV technology in Japan

    Cuttings from a test drilling in the Kuenohira district, Oita Prefecture, are subjected to analysis. The result of ground surface investigation suggested the presence of a magma reservoir to serve as heat source and a highly permeable zone along a fault to help the formation of a thermal water retention system. At the N9-KH-1 drilling site, however, no geothermal reservoir is found along the periphery of the subsidence in the western part of the research area. In this district, it is deemed, no geothermal reservoir has been formed due to shortage of heat supply from the heat source and insufficient geothermal water activity. It is also deemed that the district, in which fractures of the E-W system, NNW-SSE system, and NE-SW system are distributed, is a region at which meteoric water flows into larger convection systems. As for the westward stretch of the geothermal reservoir (where the N9-KH-1 site is situated) that has developed on the swell of the basement, detected to exist at N2-MW-2 and N3-MW-6 in the eastern part of the research area, it is found to be not so extensive.

    At COP3 in 1997, an agreement was made to the innovative technical development/promotion by international cooperation, and the promotion of transfer of environmental technology to developing countries. Under the agreement, a feasibility study of international cooperation was made, and especially a study was conducted of the utilization/development of solar energy by the innovative solar thermochemical process. The main reason for global warming is emissions of a large amount of CO2 caused by the direct combustion of fossil fuels. Therefore, a CO2 recycle system taken up in the study enables a more substantial decline in CO2 emission (kg/kWh) per unit generation than the conventional thermal power system by composing solar methanol or solar dimethyl ether using fossil fuels including coal, water, CO2, etc. as raw materials and using solar energy as heat source, and by using this as fuel (solar fuel). CO2 can be reduced by 13% to 14% by substituting solar methanol or solar dimethyl ether produced from petroleum/methane equivalent-mol mixed raw materials for the equivalent mol coal and natural gas of the thermal power plant (CO2 recovery is not necessary). 34 refs., 47 figs., 34 tabs.

Effects of the energy issue are remarkable on the next generation and thereafter as seen in the finite of energy resource, global-scale environmental changes, the increasing energy demand, natural/social influences of large-scale technology development. If the technological development is going on in the same way as until now, there will appear limits. Relating to the strategies, to seek what energy should be among the strategies, it is necessary to consider not only global-scale problems but particular conditions in Japan (self-sufficiency, international cooperation, creativity, etc.) Also, wisdom and technique are necessary to attain it. Technological development in a wide sense plays a major role in the energy strategy. Technology innovation must be advanced according to the energy strategy. Integrating ideology into the development of energy technology and selecting therefrom developmental subjects which meet the purpose, required is the construction of the energy system with high flexibility and functionality. Looking at the conventional way of thinking from a different angle and posing a future pull plan, Japan should show leadership to the world. 20 refs., 25 figs., 8 tabs.

    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.

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

    This report summarizes the fiscal 1974 research result on the solar heat power generation system with a tower light collection system. This system receives solar radiation energy by reflector group, and concentrates solar energy reflected by each reflector on the heat absorber mounted on the top of the tower. A ratio of the whole reflector group area to the receiving area of the heat absorber is called a concentration factor. The heat absorber converts concentrated dense radiation energy to thermal energy, and transfers heated thermal medium to the bottom of the tower to supply solar heat to a thermal plant after appropriate treatment. Based on the above basic idea, study was made on the total system and each subsystem, and some problems on component equipment and materials were extracted. After solving these problems and improving the whole system accuracy, these results are put to practical use for design and operation of an actual pilot plant. The main research items are as follows: feasibility study, simulation, element study, preparation of a 10kWT test equipment, and planning of a 1,000kW class pilot plant. (NEDO)

    The above-named survey had been scheduled to be conducted in fiscal years 1996-1998 for an approximately 10km{sup 2}-large area of Kokonoe-cho, Kusu-gun, Oita Prefecture. In fiscal 1996, surface surveys were conducted, such as geological and alteration zone surveys, gravity prospecting, and electromagnetic survey. In fiscal 1997, an exploration well (N9-KH-1: depth 2,222.0m) was drilled. Since the maximum temperature in the well was found to be so low as 78.5 degrees C, the survey was given up in the second year. The survey conducted at N9-KH-1 showed that deep-seated and shallow-seated ruptures developed there in the absence of aquicludes, and so it was inferred that it was a recharge area, as predicted by the temperature logging profile, with surface water flowing into the depth. The above showed that there was no deep-seated blind geothermal system which the survey was after. Since it was not likely that the shallow-seated geothermal system located in the southern part of the Mizuwake pass would be found expanding into the area of the current survey, it was decided that the survey not be carried forward to the following fiscal year.

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

    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 current most important solar energy utilization fields are solar energy power generation (solar heat and photovoltaic power generation), and solar heat cooling and heating. A solar heat power system collects or stores solar thermal energy as energy source of power systems, and converts it to electric power through heat exchange systems. To establish such system, not only R and D on a collector, absorption capsule, storage unit and heat transfer unit, but also complete study on an optimum system configuration and environmental impact are necessary. A photovoltaic power system converts solar energy to electric power directly by photoelectric conversion device such solar cell. Except specific local uses, drastic cost reduction and improvement of a conversion efficiency (at present 12-15%) and life (several years) are necessary for solar cells. Although a lot of solar heat cooling and heating systems is in practical use in Japan, for its further diffusion an important research task is development of heat collector excellent in efficiency, cost, life and maintainability.

    Financial assessment is carried out by estimating the liquefaction product cost (selling price) at which the predetermined rate of return on investment is to be earned, which is calculated by the DCF (discount cash flow) method. The cash flow is determined from the net after taxes for each business year, and the balance after the subtraction of long- and short-term borrowings is converted to the present worth as of the operation commencement year at the predetermined discount rate, and a total is calculated for the period. When the difference between the total and the equity does not vanish, the coal liquid selling price is changed, and this process is repeated until the difference vanishes. If a 20% reduction in the plant construction cost is feasible, the coal liquefaction product will be competing with the crude oil in the market in around 2030. Although the financial analysis is a profitability analysis from the fund providers' viewpoint, the benefit as seen from the project siting country needs to be assessed by an economic analysis, and probabilities are that, in the presence of great profits, the project will materialize if the two are found to earn more than average after the profits are impartially divided. Japan's benefits and expenditures are compared and subjected to an economic analysis, and a result of 6-15% is obtained. This means that the project will realize in case EIRR (economic internal rate of return) is higher than the fund procuring cost of 11%. (NEDO)

    Demand is increasing in recent years in Japan on batteries for electric power storage to respond to load variation in electric power supply. If electric power storage batteries are applied for practical use, nighttime excess power can be stored appropriately, which can be discharged during day time when the demand is increased, so that the demand variation can be handled adequately. Secondary batteries, if used, are characterized by having much greater energy density and output density because of storing the electric energy as chemical energy than in pumped-storage power generation which stores the energy as the positional energy of water. Therefore, this paper describes the surveys performed on the trend of developing the power storage batteries inside and outside the country. Section 1 shows the current status of annual load rates in other countries, and the current conception on power storage in these countries. Section 2 states the current status of practical application of power storage batteries having been developed in Germany and the U.S.A. and performed of demonstration tests. Section 3 reports the current status of developing new type power storage batteries. Section 4 describes the current status of developing the power storage batteries for power users. (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)

    A large offroad unmanned dump truck navigation system has been developed, and is in practical operation mounted on dump trucks at Torigatayama Limestone Quarry of Nittetsu Mining Company. The system functions in a manual dump truck navigation mode, wireless navigation mode, and unmanned control mode. The unmanned control mode further includes a mode to navigate the truck on a predetermined course with its data having been input in a computer and a mode that when the truck was moved on a course under a wireless control, the computer learns the course and drives the truck autonomously thereafter. The safety measures are divided into the hardware safety function to detect abnormalities in brakes and other vehicle parts, and the software safety functions of data communications, sensor action check, and prevention of collision of trucks with each other. The system has resulted in a productivity of average one-way travel distance of 345 m, and average unmanned navigation cycle time of 9 minutes and 26 seconds for a transportation efficiency of 541 t/hour/truck, having reached at least the manned operation level. 4 figs., 1 tab.

    This technology development aims at developing the design technology of the array type wind power system and the control technology to efficiently operate the system. As a result, the wind turbine produced by Micon was selected. The rated power is 100kW, and the number of the wind turbine is three. The three-phase short-circuit capacity at the generating end of the wind power generation facilities is 26,25 MVA, which can fully be broken. A simulation of voltage variation/frequency variation was made to grasp various phenomena of the output of the wind power system influencing the power source system and power distribution system. As a result, it was confirmed that it is possible to operate the system safely without lowering the quality of power. As to the overall monitor/control system which controls wind turbines, five wind turbines as many as possible are grid-interconnected and the number of wind turbine is to be controlled by a ratio of the total demand power to the gross generating output of wind power in the Miyako system, for the purpose of increasing the rate of equipment utilization of the wind power system also at the time of the lowest load of the Miyako system. In the operation of two-system interconnection, the gross power generating amount was 1,321,250 kWh, which increased 9.7% over the results in FY 1993. (NEDO)

Although the small experimental single/double effect absorption refrigerator system didn't satisfy the initial design specifications, if the large system is used, it probably satisfies them. Its wide operation range was confirmed by adding LiCl to water-LiBr system coolant. Concentration by reverse osmosis and electrodialysis for recycling absorbent resulted in failure. The storage tank volume of coolant and absorbent necessary for a heat storage refrigerator reached 4 times as large as refrigerator unit one. The primary basic plan of a single/double effect refrigerator system with plane collectors was prepared for Oita University. For system simulation, more practical characteristic equations are showed by reconsidering equations for single effect systems. The characteristic equations for double effect and single/double effect systems were obtained on the basis of the 1976 research result. The control method of hot water and absorbent effective for refrigerators was clarified. Absorbent circulation of 3.5-4% in concentration difference was optimum. (NEDO)

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

Fractures running NE-SW are dominant, and those closely related to prominent geothermal signs are found in the Akan Seibu fault group in the western part of the Akan region. The test boring results show that there are high-temperature zones of 292.1 degrees C, 194.9 degrees C, and 245.9 degrees C. Geothermal fluids were discharged by well N2-AK-7 at a rate of 4.7-4.8 t/h in steam and 0.3-0.4 t/h in neutral SO{sub 4}-HCO{sub 3} type geothermal water. High-temperature steam-dominated geothermal resources are expected to exist deep in the ground in this region, and the area where the Akan Seibu fault group is distributed may be named as a location containing promising geothermal resources.

    The FY 1998 programs for development of technologies for commercialization of industrial solar systems include those for freezing/refrigeration systems utilizing solar heat, and international joint programs for development of technologies for the solar heat-utilizing systems. The studies are also conducted to draw the technological development programs for the solar heat-utilizing systems to be developed in the future. For development of the solar heat-utilizing freezing/refrigeration systems, the efforts are directed to extending service life of hydrogen occluding alloy to at least 10 years, which is one of the final targets. High reversibility up to 1,000 cycles is confirmed with the alloy working at low temperature for generating low-temperature heat. The international joint programs for technological development include technology evaluation of lumber drying by solar heat by operating the pilot plant, training of engineers and study on commercialization of the concept in Republic of Indonesia. The studies on technological development of solar heat-utilizing systems include those on classification of the solar heat-utilizing systems by area and utilization type, and evaluation of operating temperature levels and the merits and themes/problems.

    Actualities of exhaust heat and demand for heat in the area are investigated on the result of which a wide-area energy utilization network system will be built. In fiscal 1998, further questionnaires are distributed in addition to last fiscal year's, and door-to-door visits are made on leading factories representing 10 types of industries. The result of data analysis places the nationwide total of exhaust heat at 320,000 Tcal/year including heat generated by electric power generation. When it is so defined that usable heat be above 150 degrees C for exhaust gas, above 40 degrees C for hot water, and above 200 degrees for solids, the total will be reduced to 230,000 Tcal/year. Cleaning plants (plants that treat refuse or sewage) as the sources of exhaust heat besides the factories are investigated for the amount of heat they discharge, and then it is found that the amount of heat they discharge is the fourth largest following electric power plants, iron and steel mills, and chemical plants. It is also found that most of their exhaust heat is of good quality because it is latent in steam or hot water. It is acknowledged, partly because many of such plants are situated relatively near to the urban district, that their role is important when studies are made on the utilization of exhaust heat.

    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)

    The Toyota Hybrid System has two power sources which engage depending on driving conditions. An improved efficiency gasoline engine provides the main power to drive the wheels, as in conventional automobiles. Drive power can also be supplied by an electric motor, which derives its electricity from a battery and a Generator. Fuel efficiency is further boosted by other measures, such as automatically cutting the engine when the vehicle is at a stop and regenerating the energy accumulate during deceleration. Compared with conventional vehicles with a 1.5-liter engine running in 10 {center_dot} 15 mode, the CO2 emissions are reduced by half. Moreover, with the use of a motor to reduce engine load during acceleration, HC, CO, and NOx emissions are cut significantly low levels. 13 figs.

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

    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)

    For the development of a unified performance test method for solar DHW (domestic hot water) systems, the Japan Quality Assurance Organization test was applied to three types. In an individual test, each specimen is exposed to irradiation from a solar simulator for 8 hours in a specified pattern. Upon completion of the 8-hour irradiation, hot water is taken from the specimen, the amount being 1.1 times as large as the heat accumulation tank capacity, for the measurement of the collected heat. The control of the heat medium circulation pump, flow rate, and density, all supposed to affect the heat collecting performance, are examined. Stable data, not subject to meteorological factors and high in reproducibility, is obtained, allowing a single test to represent the heat collecting performance. A system test continues for 24 hours, from 8 o`clock on this morning through 8 o`clock on the following morning, with water collected in a specified pattern. This test is suitable for examining the in-service performance of a solar hot water system including the auxiliary heat source. If temperature is not set properly in the auxiliary heat source before testing, the system performance coefficient and sun-dependency coefficient will not be expressed in a uniform manner. For a correct evaluation, measurements should be made only after a several days` uninterrupted operation for the removal of the adverse effect of the heat residual in the heat accumulation tank. 4 refs., 5 figs., 9 tabs.

    Surveys were conducted of the trends of coal companies in the U.S. and Australia and of the lookout for new coal field development in Australia for the purpose of contributing to the stable supply of coal in the future. In the U.S., the coal industry has experienced serious changes in these ten years, and various corporations, such as Peabody, Arch Coal, CONSOL, and Kennecott have come to resort to drastic measures for their survival. In Australia, coal price is lower and contract terms are shorter with less demand for coal supply thanks to the economic crisis in Asia. As for demand for coal in Asia, on the other hand, it is deemed that in 2010 there will be a 41% increase over the 1995 level and that, therefore, coal field preservation and new field exploitation are necessary. Since production by strip mining in New South Wales State is to decrease in 2012 and after, it is expected that new projects will start only after 2012. Comprehensive development projects are going to be launched in the areas surrounding the Surat district, Queensland State, and therefore new projects will be easier to start in this region. Since the Surat coal is to be collected after a little stripping, it is expected that it will be able to compete with the Indonesian coal. (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)

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

    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)

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

    NEDO is proceeding with the development of a technology to put photovoltaic power generation system for industrial use into practical use, with an aim of simultaneous solution of sustainable growth and environmental problems. In developing an advanced heat process type system, selection was made on high-performance refrigeration materials for a stand-alone type refrigeration system capable of dealing with levels of minus 20 degrees C or lower (Ti-Ni-Zr-Mn-V based hydrogen absorbing alloys for use at low temperatures, and La-Ni-Sn-Al based hydrogen absorbing alloys for regeneration use). Evaluations were given on the developed refrigeration system by using the dynamic property simulation technology. The developed system achieved a cold heat acquiring temperature of minus 20 degrees or lower, and a heat output of 1,500 kcal/hr or more under the conditions of outside air temperature of 28 degrees C, and collected solar heat temperature of 140 degrees C. CO2 reduction unit requirement was calculated from LCA on a solar heat utilization system with which the future technological development is expected to aim at. Themes proposed to be promoted in the future would include a direct heat utilization system such as the building material integrated system, a freezing and refrigeration system, a high-temperature light and heat collecting system, a harmful substance analyzing system, a high temperature utilizing fuel synthesizing system, a high-efficiency heat storing system, and a snowy cold region system.

    Large buildings such as government office building, private office building and gymnasium are consuming a huge amount of fossil fuel as energy for cooling/heating and hot water supply. The final target of this project is a use of solar heat as energy for such systems in place of fossil fuel. The fiscal 1974 target of this project is as follows. The main part of the computation program was developed for system analysis on the whole thermal system composed of building structure, thermal load, and cooling and heating equipment. The small experimental thermal equipment and artificial light source were prepared to clarify the mechanism of solar heat collectors experimentally. As the first step of innovative refrigerator development, the small trial experimental equipment was prepared to clarify heat transfer characteristics for coolant recycling, and to develop an ideal structure heat exchanger possible to reduce the temperature difference between heating medium and heated liquid. Prior to development of a heat storage equipment, basic study was made on heat storage materials, heat insulation methods and characteristics of heat storage tanks. (NEDO)

    Introduction of geothermal heat pump systems, which depend on temperature differential, is investigated for urban areas, which have large energy demands. Results of the surveys on the current situations of geothermal heat pump (GHP) systems indicate that they have already numbered 300,000 units in USA and totaled more than 50,000 units in Switzerland and Northern European countries, and that they are increasing at an annual rate of higher than 10%. The results also indicate that introduction of these systems are well feasible in Japan, which generally has better topographical conditions than American and European countries, and the GHP system with vertical ground heat exchanger is investigated for its topographical and environmental considerations. These systems could annually abate approximately 52 million tons of CO2 (4.3% decrease), if disseminated to all households. They are also expected to help control the heat island phenomenon, and reduce peak power consumption. The technological problems to be solved before these systems are massively disseminated including development of small scale drilling rigs and preparation of drilling manuals. System standardization and introduction of subsidy systems are also needed to massively disseminate these systems. (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)

    This report describes the fiscal 1974 R and D result on solar cooling/heating and hot water supply systems for apartment houses. In system analysis, the system plan was selected through basic data survey, modeling by combining some kinds of such systems and energy flow calculation. On solar heat collector, theoretical analysis was made on a stationary plane collector, and study was made on cover glass material and absorption surface performances. On Rankine's engine, studies on advanced selective absorption film, transmissive film, prevention of heat radiation and converging collector were necessary. As solar heat driving refrigerators, absorptive one and Rankine's one were promising. As heat media for refrigerators, R-11 and 113, and R-114 and 11 were suitable for turbo one and displacement one, respectively. Since a displacement compressor is featured by high-efficiency lower-speed operation than that of turbo one without any constraint, its direct connection with a motor or generator is possible. Screw compressor belonging to displacement one was promising. Rotary displacement one was also promising in a small-capacity range within 20-50RT. (NEDO)

    The paper described the fiscal 1997 result of the fracture hydraulic exploration method as the variation exploration method of geothermal reservoirs. By elucidating hydraulic characteristics of the fracture system forming reservoir, technologies are established which are effective for the reservoir evaluation in early stages of development, maintenance of stable power after operational start-up, and extraction of peripheral reservoirs. As for the pressure transient test method, a test supporting system was basically designed to obtain high accuracy hydraulic parameters. As to the tiltmeter fracture monitoring method, a simulation was made for distribution of active fractures and evaluation of hydraulic constants without drilling wells. In relation to the two-phase flow measuring method, for stable steam production, the use of the orifice plate, the existing flow measuring method, etc. was forecast as a simple measuring method of the two-phase state of reservoir. Concerning the hydrophone VSP method, a feasibility study was made of the practical VSP for high temperature which can analyze hydraulic characteristics and geological structures around the well at the same time which the existing methods were unable to grasp, and brought the results. Moreover, to make high accuracy reservoir modeling possible, Doppler borehole televiewer was made in each reservoir. 80 refs., 147 figs., 22 tabs.

    Efforts are under way to develop reservoir change evaluation technologies to be effective in evaluating reservoirs at their initial stage of development, in stabilizing the output of power stations after their commencement of service operation, and in probing into reservoirs in already-developed areas. One of them concerns the characterization of the hydrological properties of fractures. The development efforts involve (1) a pressure transient test method (measurement of the response of reservoirs to changes in borehole internal pressure), (2) a tiltmeter observation method (ground surface deformation measurement), and (3) a 2-phase flow metering method (metering of spurting fluids). Under item (1), a computer-aided borehole hydrology test system is built and field-tested to isolate problems. Also, a pressure transient test system is built by way of trial by use of which compressor-aided control is performed over air pressure in the borehole. Under item (2), it is made clear that changes, several MPa in scale, in the pressure in a borehole is detected by simulation and that a sufficiently capable system is realized using a tiltmeter available on the market. Under item (3), a device is fabricated which is a combination of a laser flowmeter and a void fraction meter, and a field test is conducted to assess its feasibility and to identify problems. (NEDO)

    For every solar energy utilization field, its background, feasibility, impact in practical use, and R and D policy in Japan were studied. Heating and hot water supply by solar energy are already practical because of less technical problems and reasonable profitability, and cooling is also practical as far as a technical viewpoint. At present, the technical level of solar heat power generation is in the stage of basic technology, however, in the future, development of economically reasonable systems will be demanded as well as establishment of its technology. The most difficult problem for realizing practical solar cell power generation systems is cost reduction. It is also another problem that a big demand of Si for solar cells further exceeds the current yield of Si in a semiconductor industry. A small-scale hybrid solar cell power generation system applicable to the roof of general residences is already feasible. Although a solar furnace is still poor in application to industrial fields, it is expected as the leading part for a future solar heat chemical industry. (NEDO)

    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.

    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.

The cooling using latent heat of vaporization of the water supplied makes the temperature distribution inside the cell face homogeneous. In the test for long life, the system was stably operated at voltage lowering speed of 11mV/1000h. The optimization of water supply structure in the stack increases the latent heat cooling amount and makes the temperature distribution inside the cell face homogeneous. The reduction of CO concentration in reformed gas is extremely important for improvement of cell performance and long-term stabilization of cell voltage. By the two-stage structure selective oxidation device, the CO concentration at inlet, 5,000 ppm, can be reduced to below 10 ppm at outlet. In the demonstrative experiment on the several 10 kW class dispersed generation system, efforts for reduction in size of structural equipment and package were made, and a possible size of 200*150*180cm was obtained. Based on the chart of 30kW class system flow, the heat material balance was analyzed, and the power generation efficiency of 40% at a.c. sending end and overall efficiency of 80% were confirmed.

    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)

    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)

    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.

The report includes the system analysis result (collection of existing technical data, analysis of weather conditions, profitability assessment, concept design of the primary experimental house), and the research result on equipment and materials (view and evaluation of existing technologies, selective transparent and absorption materials, the primary prototype solar heat collector model, refrigerator). As the study result, the spheroidal experimental house was adopted. The solar heat utilization system is a central air-conditioning equipment composed of heating by hot water obtained from the solar heat collector, and cooling by absorption refrigerator. Heat collection efficiencies were measured for (1) stainless steel substrate collector, (2) copper substrate collector, and (3) glass pipe collector prepared as prototype collectors. (2) was higher in heat collection efficiency than (1). The efficiency of (3) hardly increased by rise in heat collection temperature due to vacuum structure and selective absorption membrane. Further measurement of such characteristics is necessary at higher temperatures. (NEDO)

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

    Technology is discussed of detecting structures buried in the ground by use of a forward-looking sensor mounted on the drill head for the avoidance of collision with such structures during application of the flowmole method in urban districts. In this detection system, pulsating radio signals are emitted from a transmission antenna and the received signals are converted into low-frequency signals in a sampling circuit for eventual display on a B-scope. Since the drill head for flowmole technology is as small as approximately 50-60mm in diameter, experiment is conducted to know the detectability of a very small antenna directed at a buried pipe. The basic phase of the experiment using the very small antenna includes a soil-filled tank test and field test. It is then found that the very small antenna is capable of detecting the steel pipe buried 50cm away from the antenna with the antenna directed at the said pipe. In a test wherein a very small antenna is allowed to rotate on the drill propelling shaft, the design simulating a revolving drill head, it is learned that the detecting system under study will identify the direction in which a buried structure exists. 1 ref., 9 figs.

    Grasping the present situation of coal utilization technology in the Philippines, the paper proposed a feasibility study of introduction of the environmentally friendly type coal utilization system which seems to be needed in the future. (1) Introduction of the environmentally friendly type coal utilization system in the electric power generation sector: there are only four full-scale running coal thermal power plants in the Philippines. In the future, several coal thermal plants are planned to be constructed by 2005, but for the new installation, it is desirable to adopt fluidized bed boilers with wide application to coal kinds. In case of 0.3-1.0 million MW class plants, it is planned to adopt high grade import coals, and it will be natural to fire pulverized coal. For the processing of flue gas, it is a must to install desulfurization facilities and smoke/soot removal devices. (2) Utilization/development of domestic low grade coals: at the mine-mouth generating plant, it is necessary to investigate the economically minable amount of coal, confirm productivity, survey coal quality, etc., and select boiler. As to coal briquetting technology, it is necessary to examine coal quality for tests and make a thorough study of what technology is most suitable. 50 figs., 78 tabs.

    As a part of the FY 1997 survey of the promotion of geothermal development, the gravity filter analysis was made of the data processing in the Tsujino-dake area of Kagoshima prefecture, and the results were summarized. The geothermal fluid used in the Yamagawa geothermal power plant has the residual magma brought by activities of volcanic rocks of the Ata central shield volcano as heat source, and the fracture system and deep intrusive rocks are reservoirs. A small scale of gravity anomaly area is located, and it reflects high-density volcanic rock masses which are distributed on the earth surface or shallowly under the ground. The ridge stretching from Kiyomi-dake to the Narukawa tunnel and the ridge connecting Kuze-dake and Tsujino-dake are in the high-gravity area and reflect high-density rocks in the shallow part and deep part. There is a possibility of the existence of the fracture system in the high-density deep basement. Calderas continue close to the south of the high-gravity ridge stretching from the Kiyomi-dake to the Narukawa tunnel, and the fracture system which brings the eruption of volcanic rocks of the Ata central shield volcano and the fracture system forming caldera exist in parallel. From the aspect of the geothermal structure, a consideration was made of rock layers which possibly compose the rise of high-density basement in the deep part near the Tsujino-dake. (NEDO)

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

    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.

    This project is aimed at technological development of economical solar energy systems for air conditioning and hot water supply for condominiums. The major items for the FY 1977 programs include (1) designs and fabrication of equipment for a test building, (2) development of the equipment materials, and (3) system analysis. The jobs for item (1) include management of the designs and construction, placing an order for the building, and fabrication of an air conditioner expander and heat pump; those for item (2) include simplification of a condensing type and plate type heat collector structures, weather-resistance of the plate type heat collector structure, and materials for selective absorbing membranes and reflectors; and those for item (3) include estimation of heat loads in a model building, first to third floors as the test building, and fourth to 14th floors as the conventional box-shaped building. The heat collector installation area is investigated for a multistory building, for which solar radiation intensity at the heat-receiving plane and the like are taken into account. It is found that the solar system can be installed, when an area of 50m{sup 2} can be allocated to the system in each story. There is a limit to story number for the solar system to economically work for air conditioning and hot water supply. Sufficient insulation of the system and reduction in pipe length by zoning are the necessary measures against heat losses. (NEDO)

    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)

    This paper describes the achievements in fiscal 2000 from the WE-NET Phase II for Task-5, the development of a hydrogen fueled automobile system. For a fast filling method using a hydrogen absorbing alloy as the fuel tank, a rare earth system, the Laves system, and a body-centered cubic system were selected to discuss filling time when the plate-fin system tank and the divided system tank are used. Either system was found capable of filling 80% of the effective hydrogen absorbing amount within 10 minutes, having achieved the target. Guidelines were obtained for the design aiding method by using the cooling water flow rates, temperatures, and simulations. In the safety assessment, even the spontaneously combusting alloy of Category 1 in the Fire Fighting Law did not cause ignition even if the tank was damaged and the alloy was discharged in the dropping/falling weight tests. It was inferred that the ignition temperature is not reached because of the self-cooling made when hydrogen is discharged from the alloy. In the fire resistance test, the tank temperature was found not to rise as long as hydrogen is discharged from the alloy. Since the temperature rise and damage could occur if the discharge has been finished completely, discussions are required on materials and the soluble plug. Deformation may occur in the initial stage of the hydrogen absorbing and discharging cycles, but it would not occur after 5,000 cycles. (NEDO)

    This report describes the fiscal 1974 research result on metal system materials for solar cooling/heating and hot water supply systems. Study was made on cathodic protection of a roll bond heat collection board promising as Al plane collector. The protection is dependent on sacrificial anode materials. Al-Zn system alloy including minute amounts of In and Sn was effective in protection by transferring natural electrode potential to a base side largely, however, excess addition of In and Sn increased self-corrosion, remaining some issues to be solved. The prototype water flow corrosion test equipment was prepared for corrosion analysis of an Al roll bond collector natural circulation hot water supplier. Preliminary study was made to give selective absorption power (large short-wave absorption and small long-wave radiation from collector surfaces) to a collector. Deposition of Cu, Ni, Co and Sn oxides as black semiconductors into Al anodic oxidation film porous layers by secondary electrolysis was invalid as well as a painting method. Glossy Ni plating onto Al and black Cr and Ni plating onto the surface more elevated solar exposure surface temperature by more than 20% than black painting. (NEDO)

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

    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.

    Researches were conducted for the goal of proposing a totally new process enhanced in efficiency and energy saving, and capable of CO2 separation. In fiscal 1997, hydrocarbon materials were reformed by oxygen separated within a system allowing fuel cells to generate power efficiently, when all the emitted CO2 was separated and recovered within the system. Furthermore, cold heat was utilized for the acquisition of liquefied CO2 gas products. A part of oxygen separated at the fuel cell cathode was recycled into the combustion section external to the tubular reaction reformer, and CO2 was separated by mere cooling from the combustion products for the simultaneous production of by-products such as high-purity nitrogen gas and liquefied CO2 for a great improvement in economy. In fiscal 1998, the system was improved. Proposed then was a new system in which an oxygen partial oxidation type reformer assumed the nuclear role, separating all the oxygen at the cathode, reusing part thereof for oxygen enrichment, and feeding the rest thereof into the reformer. The design realized the recycling of the whole of the products of the two cell electrodes into the reformer for the maximum reuse of the products of the hydrogen/oxygen separation function. (NEDO)

    Surveys were made on the present state of R and D strategies such as energy conservation technologies and high performance technologies among private firms in the U.S. and Japan, for the purpose of suggesting direction of R and D for Japanese private firms and contributing to the R and D policies in the future. The R and D strategy trends of Japanese private firms are, for example, shortened R and D period, market needs in R and D and emphasis on direct links to product development, lack of researchers, R and D outsourcing, and introduction of project team system. In the U.S., firms are showing signs of revival of their R and D activities that have been on the wane since 1980s. The focus of R and D contents has been shifting from basic to applied researches. In the efforts of compensating reduced basic researches, the firms are beginning to establish a cooperation system through alliances with outside research institutions by throwing away the completely independent principle. The private firms are also advancing alliances with venture firms. The firms are presumably taking in the idea of financial products in their investments in R and D. (NEDO)

    Taking the area of the clean coal technology (CCT) effective for energy conservation and environment preservation as the object, a feasibility survey has been performed on executing a model project in India. About 70% of the total power generation capacity in India depends upon coals existing in abundance inside the country. Since the local coals are high in ash, low in sulfur, and low in calorie, the environmental problem related to thermal power plants is the disposition of fly ash. The Central Electricity Authority of India expects solving this problem by CCT introduction. It also expects increase in combustion efficiency by using ultra-critical boilers. The Indian cement industry often uses in-house electric power generation facilities because of high electric power cost, wherein the produced coal ash is used as a cement raw material. The matter of the strongest interest is the introduction of a high-efficiency combustion system that depends on low-grade coals. Among the CCTs, strong interest was shown in the fluidized bed cement kiln and the circulating fluidized bed boiler. The iron and steel industry has expectations toward effective coal washing technologies and coke manufacturing technologies. (NEDO)

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

    The paper summed up the results of the geothermal development promotion survey B 'Mt. Tsujinodake area' which was carried out at Yamagawa town, Ibusuki county, Kagoshima prefecture, from FY 1997 to FY 1999. In the survey, the following were conducted: surface survey such as geology/alteration zone survey, fluid geochemical survey, gravity exploration and electromagnetic exploration, and geothermal fluid survey by drilling 4 structural testing boreholes. In the Mt. Tsujinodake area, active fumarolic activities are still now continuing around the Unagi hot spring in the north, and the acidic alteration zone is distributed in the peripheral surface area. In Borehole N11-TD-2 in the north, it is assumed that there exists the hydrothermal bed of a temperature of approximately 230 degrees C in the depth of 400-800m, which is comparatively shallow, and that the stored geothermal water flows laterally. In the central area, a hydrothermal bed of a temperature of approximately 130 degrees C was confirmed in N11-TD-1, but it is judged that chances of the existence of high temperature hydrothermal bed are not very good. In N11-TD-3 in the south, the existence of promising heat sources is expected in the deeper part since the remarkable alteration was seen in the depth of 1,435m or deeper, and the sharp rise in temperature was recognized.

    The paper summed up the results of the geothermal development promotion survey 'Mt. Aso West area' which was carried out at Choyo village and Kugino village, Aso county, and at Otsu town, Kikuchi county, Kumamoto prefecture, from FY 1991 to FY 1994. In the survey, the following were conducted for the comprehensive analysis: surface survey such as geology/alteration zone survey, geochemical survey and high precision MT method survey, and temperature log, electrical log, water injection test, core test and hydrothermal survey by drilling 7 structural boreholes. In the numerical analysis of thermal structure models, the present geothermal manifestation was obtained, assuming that the past magma reservoir in a state of agglomeration/semi-agglomeration exists in the depths of caldera and that the depth is set at 4km. It is assumed that the deep hydrothermal reservoir around Yunoya/Tarutama exists around the depth of 500-600m below sea level and that the temperature is 230-300 degrees C. The meteoric water permeating into the depths forms high-temperature reservoirs around Yunoya/Tarutama. The reservoir rises up to about 400m below sea level to become a vapor-dominated phase. It forms an acidic SO{sub 4} type reservoir phase around the earth surface. (NEDO)

    A geological structure survey was conducted in the Rajah mining field, New Zealand, to study coil exploitability there. Conducted were the drilling of five boreholes (and three more by Solid Energy Corporation, New Zealand), surface exploration, surface survey, borehole core specimen examination, coal specimen analysis, and the like. It was found that the coal from this field includes 3-5% of ash and 0.3-0.4% of sulfur and therefore is excellent as coal for coke making. There are three working coal beds, 1.7m at the thinnest section and approximately 7m at the thickest section. It is concluded, on the assumption that sections not less than 2m in thickness are productive, that there are approximately 15-million tons in reserve. Since the coal beds are inclined and very variable in thickness, it is believed that hydraulic coal mining will be the best method to use. Water for hydraulic coal mining is sufficiently supplied from rivers in the neighborhood. The field is located near Rapahoe which serves as depot for coal produced in this area, is equipped with facilities for shipment by rail, and has various industries necessary for supporting coal mine operation. Coal is shipped from Greymouth Port in the area aboard 8,000-tons class barges. (NEDO)

    In order to identify the possibility of a hot rock power generation system, technological R and D has been performed on structuring of a man-made hydrothermal system, fracture mapping, downhole measurement and a circulating extraction system. This paper summarizes the achievements in fiscal 2000. With regard to the long-term circulating extraction test, a circulating heat extraction and test device was installed at the hot rock experimental field in the Hijiori area in Yamagata Prefecture, where geochemical data collection and tests including analyses thereon have begun. In reservoir bed analysis, a well module was incorporated into a reservoir bed simulator to improve the module so that comparison with the data of actual production on the ground can be performed. For the fracture mapping, AE having been observed during the long-term circulation test was analyzed, whereas it was estimated that the seismic source would not move or expanded during this period. A PTS logging has been performed during the long-term circulation test to investigate characteristics of the flow-out zone of the injection well and the production zone of the production well. In making the fracture model, an initial model was fabricated to estimate heat extraction behavior in the long-term circulation test. (NEDO)

    For the purpose of establishing a life evaluation method for power conditioner of about several kilowatts for general housing use, the acceleration test was made, and the data were summarized for maintenance of power quality, cooperation with the protection system at power system, insuring of safety of personnel/facilities, etc. As to the acceleration method, by paying attention to heat deterioration of thermal plasticity materials being used for power conditioner and by using the acceleration method using the 10-degree C half law by the Arrhenius law, temperature and humidity were set at 40 degrees C and 36%, respectively. The operation hour and stopping time were fixed at 3.5 hours and 4.5 hours, respectively. The life evaluation measurement by the acceleration test was composed of the continuous evaluation measurement with the aim of early finding the degradation of performance, anomaly, etc. of power conditioner and of the evaluation measurement at specified intervals with the aim of precisely measuring the state of degradation of power conditioner. As a result of the continuous evaluation measurement, the paper reported the data on the rise in temperature inside the power conditioner during the acceleration test and the change in electric characteristics of input/output.

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

    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)

    This report provides the development of new exploration technology using elastic waves, such as reflection seismic survey, VSP, and seismic tomography, for precisely characterizing subsurface fractures in geothermal reservoirs. In order to investigate and improve the effective data acquisition and analysis methods for detecting a fault type of fractures, an experiment of a seismic tomography method was conducted using wells drilled in the Ogiri geothermal field, Aira-gun, Kagoshima Prefecture. An experiment of propagation characteristics of piezo type underground seismic source in the volcanic field was also conducted as a trend survey of underground seismic sources. The fracture type in the model field was systematically analyzed by measuring the core samples obtained in the demonstration test field through remanence measurement, fluid inclusion measurement, and zircon measurement using test equipment, and by analyzing results obtained from cores and results of seismic tomography obtained from the wells. Based on these results, the effectiveness and practical application of exploration methods using elastic waves were investigated. 80 refs., 250 figs., 49 tabs.

    Japan as an ISO member country identifies the state of discussions in the environmental management standard deliberation committee at ISO. Investigations were performed on international standardization of environmental management systems for the purpose of participating and cooperating in preparing and establishing international standards related to environmental management, and playing part in working, solving and improving environmental problems. Under the circumstances that environmental problems are drawing worldwide interest, the International Organization for Standardization (ISO) has been carrying out since 1993 deliberations on environmental management standards to institutionalize environmental management rules to check effects of business activities on the environment. The International Organization for Standardization/Environmental Management Technical Committee (ISO/TC207) was installed, at which series number of 1400 order was allotted for environmental management related standards, and major standards have come to a final stage of standard formulation at the TC207 Oslo conference in June 1995. In Japan, the Ministry of International Trade and Industry has established an environmental management standard deliberation committee composed of people of experience or academic standing to advance discussions on how the environmental management should be in business entities through deliberations on ISO standards.

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

    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.

    The ventilation system for removing odor and dust was studied for the waste stock yard and working yard of a segregated waste stock facility of 17,280m{sup 3} in air volume. The developed ventilation system includes the air curtain and wind shield plate between the waste stock yard and working yard. Air curtain flow is formed by jet stream from nozzles installed at certain constant intervals. This system was developed through air flow analysis, model experiment, and field measurement. The air flow analysis pointed out that reverse flow derived from a part of air flow contaminates the working yard, however, this system can exclude such reverse flow and reduce CO2 concentration to 1/80. The model experiment result showed that this system can reduce CO2 concentration to 1/18. The field measurement confirmed the air curtain effect by smoke visualization. In the measurement of dummy dust concentration generated for 15min, this system was possible to reduce the concentration to 1/7. 4 refs., 18 figs., 6 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.

    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)

    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)

    With an objective of establishing a method for evaluating performance of a photovoltaic hot water supply system, a discussion was given on utilization of the simulation program, TRANSYS. The discussion was addressed on a photovoltaic hot water supply system of forcible circulation type using commercially available open-type heat storage tanks. An experiment was performed as an indoor test using an artificial solar light source. The TRANSYS makes available a type 04 which handles each node as a complete mixture by fixing and dividing the heat storage tank, and a type 38 which expresses heat transfer between temperature layers by means of piston flow as a heat transfer coefficient. Both types were subjected to calculation. The result of the discussion may be summarized as follows: both types provided values close to the experimental values of quantity of heat derived by utilizing solar heat; however, with the type 04, heat transfer cannot be modeled if the system is left still with temperature difference in the heat storage tank being large; and with the type 38, modeling is possible when the system is left still with temperature difference in the heat storage tank being large, but temperature gradient is difficult to be modeled during heat collection and when hot water is supplied. 1 ref., 7 figs., 5 tabs.

    For the purpose of working out a comprehensive master plan for application of the coal utilization system, the paper surveyed and studied the coal utilization system in terms of environmental measures and efficiency improvement in the utilization of coal. As a result of the discussion with NEDO and the National Planning Committee of China, Liaoning Province (the whole China) and Shenyang City were selected as a model area and a model city for the survey and study. As energy conservation measures taken in the former, desirable are intensifying/capacity-increase of boilers, kilns, etc. and adoption of new-type/high-efficient equipment. Also expected are reinforcement of combustion control and improvement of efficiency by using coal preparation, industrial use coal briquette, etc. Measures taken in the latter are the same as those taken in the whole China. As SOx reduction measures for Liaoning Province, desirable is installation of dry-type desulfurization equipment and simple desulfurization equipment. As dust prevention measures for it, desirable is installation of electrostatic precipitators or high-functional bag filters. SOx reduction measures for Shenyang City are the same as those taken in the whole China. SOx can be reduced by using coal-prepared low-sulfur coal and industrial use coal briquette added with desulfurizing agent. 88 figs., 163 tabs.

It is necessary to deepen quickly scientific understanding of the problems, and identify accurately their impacts on human bodies and ecological systems. Within the limitation of the scientific understanding, political decisions on economy and environmental risks are also important and difficult questions, with the environmental hormones being the typical examples. Establishing chemical substance verification systems is important, whereas joint researches by Japan and the U.S.A. are desired. Policy decisions on handling the researches must also be made jointly, and acceptance by citizens must be asked for at international workshops. While energies are the base of economic activities, and the sustained development thereof is indispensable, how to take balance with health and environment in the global scale is a large assignment. Joint Japan-U.S. discussions are required on technological innovation, such as for regenerative energies, energy conservation, safety of and wastes from nuclear reactors, clean use of fossil fuels, and fuel cells. International cooperation, including that from developing countries, is also important. (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)

    By the use of superconductive technology, the following are aimed at: marked reduction in power loss of electrical equipment and power transmission path, and size/weight reduction in electrical devices by high current/magnetic flux density. The superconductive technology has advantages such as great energy saving effect, CO2 reduction and global environmental preservation. As an example, concerning the superconductive generator now being developed under the New Sunshine Project, power loss can be reduced by half, and by the use of high magnetic field, size/weight can be reduced such as reduction in rotor diameter and reduction in weight by half. Further, as an innovative system, cited are the superconducting magnetic energy storage system (SMES) and flywheel energy storage system. The superconducting magnetic levitation railway, medical use MRI, etc. have also innovativity which is difficult to get in the conventional technology. Effects are also expected of introducing the process development using superconducting magnet such as magnetic separation, electromagnetic metallurgy, electromagnetic agitation and monocrytal growth convection control. Also cited is Josephson electronic device. High performance SQUID in bio-magnetic/non-destructive inspection is also expected to be developed. (NEDO)

    Highly value-added products considering a total life-cycle of products by integrating both production and consumption activities are much in demand, and each information corresponding to each product should be realized by concept integrating both information and product as common element. Survey was made on what a social system integrating production and consumption should be, a product information model, and technology integrating both information and product for raw material, industrial machine and household appliance as examples. An information model shared by the whole production and consumption activities was first prepared. Based on this model, data storage, update, retrieval and dispatch technologies were surveyed and developed for life-cycle systems. Degradation and life sensing technology was surveyed for maintenance, repair and disposal activities using proper unstable information of each product. A support system for use of shared information was developed to promote a new highly value-added function. Total evaluation was made on information sharing product life-cycle systems. 10 refs., 23 figs., 7 tabs.

    Recently, with a progress of robust control such as H{infinity} control, the application of a control system design considering a robustness of controlled system fluctuation to real machinery became possible. In addition, LMI (Linear Matrix Inequality) control system design method is superior to conventional H{infinity} control, although including various difficult elements. The design algorithm permitting the robust control system design of non-linear problems by giving controlled systems was thus developed by introducing an inverse LMI control design method. This design algorithm determines the solution of models outputting the deviation between a target value and controlled variables by solving the simultaneous equations composed of a linear matrix inequality under an impulse response constraint condition and that under an H{infinity} norm constraint condition. This technique allows to give a pending step response as control condition. The technique was confirmed to be effective by its application to the position keeping control problem of marine floating structures. 6 refs., 11 figs., 2 tabs.

    With an objective to achieve higher efficiency, higher density, and higher stability in power systems, research and development has been performed on superconductor power generators. This paper summarizes the achievements thereof in fiscal 1999. A verification test was given on the rotor of an ultra high speed responding generator. In a sudden short circuit test using the different phase charging method, no anomalies were found such as quench generation and vibration changes, wherein the healthiness of the generator was verified. In the VVVF actuation test, knowledge was acquired on the actuation method when the ultra high speed responding generator is applied to a combined cycle plant. After the verification test has been completed, the disassembly inspections such as visual check and non-destructive test were performed. With regard to the vacuum leakage found in the rotor under very low temperatures, the causes were presumed and the countermeasures were discussed by observing the weld structures. In the design research, the conception design on the 200-MW pilot generator was reviewed by reflecting the results of the verification tests on the model generator. At the same time, trial design was made on a 600-MW target generator. In summarizing the overall research achievements, the achievements and evaluations were summarized on technological issues that have been allotted to each research member. (NEDO)

    Research and development was conducted aiming at the establishment of a system to enable the high-efficiency expression of the gene products of P. horikoshii OT3 and A. pernix K1. In an effort to develop a high-efficiency protein expression system with Escherichia coli acting as the host, studies were made about the expression of hyperthermophile protein by arginine rare codon elimination, and Ph FEN (flap endonuclease) was successfully overexpressed. In the development of Bacillus strains, screening was conducted for novel hosts, and a library was constructed for a screening task suitable for hyperthermophile-derived protein production. A system was also constructed capable of the high-throughput expression of various kinds of genes using Bacillus brevis. In the study of the expression of hyperthermophile-derived genes using T. thermophilus, promoter replacement resulted in an approximately 2-fold increase in representation at the maximum. Moreover, studies were made about the length at which foreign genes were efficiently incorporated into the T. thermophilus genome. (NEDO)

    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.

    This paper reports the study results on R and D of nickel-hydride storage battery for photovoltaic generation systems in fiscal 1994. (1) On the study on low-cost electrode materials, the physical properties and electrode characteristics were studied of the prototype hydrogen absorbing alloys prepared by substituting Cu or Ni for Co in Mm(Ni-Co-Mn-Al)5 (Mm: mixture of rare earth elements). The result clarified that it is difficult to reduce Co content in the alloy to 0.4 atom or less. Simple heat treatment and milling processes in production of hydrogen absorbing alloy electrodes were achieved by adopting an improved metal mold and gas atomization method. Characteristics and cycle life of the Ni positive electrode prepared by applying active paste material of Ni(OH)2 were studied, however, the result showed only lives of nearly 300 cycles. (2) On the study on electrode structure for high-performance (long-life) battery, the 3-D porous metal electrode support was evaluated, and various battery configurations were studied. 11 figs., 1 tab.

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

    Described herein are the results of the FY1994 research program for operational studies on a large-scale wind energy conversion system. A total of 8 domestic and foreign cases are studied for wind energy conversion cost, to clarify the causes for higher cost of the Japanese system. The wind power systems studied include Japanese (5 units at Tappi Wind Park, the same type supplied by company M), US (California Wind Farm, 300 units) and UK (Wales Wind Farm, 103 units) systems. The investment costs are 639, 285 and 189 thousand yen/kW for the Japanese, US and UK systems, respectively. It is also revealed that the power plant itself and assembling costs account for a majority (70 to 88%) of the total investment cost. The higher cost of the Japanese system results from a smaller number of units installed, and the power plant cost can be drastically reduced by mass production. Increasing size also reduces cost greatly.

    We have developed a new cooling system for the engine of construction machinery. This system produces two different air flow routes by a double suction type centrifugal fan with backward blades. We first measured aerodynamic performance and sound level of the double suction type fan, which consists of two single suction type fans of different design, and compared these measurements to those of single suction type fans. Next, we installed the fan in a scale model of the new cooling system. The performance of this double suction type fan was different to that of a single suction type. It is considered that the effect of interaction of the exit flows from the two different fans caused this performance change. The test model installed in an engine compartment showed that this cooling system reduced the area of air inlets and outlets around the engine and did not cause re-circulation of cooling air.

    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)

    For the evaluation of effects of geothermal development on the peripheral environment in the Kaminoyu/Santai area in the southwest part of Hokkaido, survey of the present situation of the environment was made. As a result of the survey, as to the climate of this area, the mean temperature, precipitation, etc. were almost the same as those of the nearest meteorological office of Hakodate, and the wind velocity was lower. Concerning the air, the mean concentration of H{sub 2}S was 0.8-3.6 ppb, SO2 was less than the detectable limiting value, Hg was 0.018-0.12 {mu}g/m{sup 3}N in average, and suspended particulate was 0.014-0.028 mg/m{sup 3}. Each of them satisfied the environmental criteria and the control level. The water quality satisfied the AA type criteria at every point of the river surveyed. The noise/vibration at the time of well drilling were 47-50dB at 10m measuring point and less than the lower limit of measuring at measuring points farther than 50m measuring point/100m measuring point. Every hot spring was drilled and spontaneously welling, and variations in spring temperature/welling amount were comparatively small. Micro earthquakes of 495 were observed in 47 days in total. Besides, survey was made of animals, plants, soils, scenery, etc. (NEDO)

    For the purpose of the improvement of coal utilization technology and environmental preservation, the paper conducted the pre-survey of the introduction of coke oven gas desulfurization facilities in China and pre-survey of potentiality of the environmentally friendly type coal utilization system in India. The pre-survey in China was made for Anyang Steel Group Co. Ltd. and Laiwu Steel Group Co. Ltd. to judge their adaptability as site for the demonstrative project on the introduction of coke oven gas desulfurization facilities. As a result, it was confirmed that the former satisfied the conditions on Japan side such as the space for installation and prospect for fund raising. However, the amount of COG treatment was larger than that planned at Japan side, and it was found that as to the recovered sulfur, the company wanted the solid sulfur different from the fused sulfur planned at Japan side. In the survey in India, explanations were made to India of CFBC and the fluidized bed cement sintering system, bio-briquette production facilities, facilities for environmental measures, coal reforming technology, etc. At the same time, the site survey was made to examine/analyze possibilities of spread/development of Japan's CCT.

    Efforts were made to establish standards necessary to promote the research and development of hydrogen energy technology and the practical application and popularization of the technology. In the study of the base of hydrogen energy technology standardization, research was conducted about Japan's difference from other countries and tasks to discharge and problems to solve in this country, relative to laws and regulations governing the construction of 'hydrogen supply stations' constituting the core of studies in the above-mentioned phase II research and development efforts. Studies conducted toward diffusion into the general public included rules and regulations over the size of hydrogen storage and the distance between dangerous matters and fire. ISO/TC197 (hydrogen technology) was established with the aim of achieving standardization of the system and equipment pertaining to the production, storage, transportation, measurement, and utilization of hydrogen for energy purposes. In fiscal 2000, Working Group 1 registered an 'interface for automated liquid hydrogen fuel delivery system' and 'hydrogen product specifications.' Moreover, Working Groups 2 through 7 were also engaged in their activities, respectively. (NEDO)

    The results of surveys conducted in the eastern part of Obanazawa region, Yamagata Prefecture, in fiscal 1988-1989 are compiled in this report. Conducted were a geological/alteration zone survey, geochemical survey, electromagnetic surveillance (TDEM - time domain electromagnetic method), gravity prospecting (review of gravity data), electric prospecting (Schlumberger method), heat flow rate survey, test boring, environmental impact survey, and so forth. Conclusions are mentioned below. It is inferred that the water of the Ginzan hot spring of the neutral Cl-SO{sub 4} type originates in meteoric water in mountains high above the mean sea level in the western side and that the hot spring water is produced when water heated to approximately 170 degrees C at a depth (1,500-2,000 meters below mean sea level) in the Ginzan hot spring district, where the ground temperature is the highest in this region, is diluted by groundwater near the surface at its ultimate stage of ascent. The survey results disclose that possibilities are quite low that a high-temperature sector of 200 degrees C or higher is found at a level not deeper than 2,000 meters from the ground surface. Accordingly, no geothermal development by flash steam power generation is feasible at the present stage at any economically acceptable depth. (NEDO)

    As part of establishing an environmental harmony type production system of chemical products, study and survey were made on PET bottles. Using the life cycle analysis method (LCA), a study was made for proposing a material recycle (MR) method which is environmentally and economically excellent in the stage of recycling waste PET bottles. The total cost of recycling can be reduced by 34% supported by a decrease in equipment cost and improvement in yield if there is no mixture of foreign substances such as aluminum caps and PVC bottles. However, the ratio of the amount obtained from the reduction to the total production cost is small, and it is necessary to take measures from a viewpoint of the cost in a total production process and environmental loads. In a survey in Kawaguchi city, PET bottles discharged from the business sector occupied 41% of all the discharge amount. In a survey in Yokohama city, very important data were obtained on PET bottles appointed as the second type under the recycle law. The quality of PET bottles to be brought to the recycling plant is important for effectively processing PET bottles in MR method. For achievement of MR which is low in cost and small in environmental load, needed were cooperation by citizens, the shipping management system in autonomous government, and changes in design and material quality to be made by the industrial circle. 8 refs., 64 figs., 68 tabs.

    R and D has been performed on a method to identify change in the gravity generated by steam production activities, and to forecast spread of the reservoir beds and future variation, as a technology effective to evaluate reservoir beds in the initial stage of development, to maintain output stability of power plants after having started the operation and to extract reservoirs existing in the vicinity of areas that have already been developed. This paper summarizes the achievements in fiscal 2000. With regard to structuring a gravitation measurement network system, ten gravity measurement points were modified and/or newly installed. The result of concentrated measurements during the current fiscal year revealed how the gravity varies before and after suspension of the steam production in association with regular repair works. Other works included patrolling gravity measurements in ten water level observation well drilling points, GPS measurements on all the gravity measurement points, continuous ground water level observation, and water content measurement for TDR soil. In the gravity variation analysis, it was indicated that the gravity variation at No. 5 hole site, the ground water level fluctuation, and the water content change in TDR soil have definite correlation with the seasonal variation. Discussions were given on a method for correction thereof. (NEDO)

    In order to plan preventive measures from the occurrence of electric power transmission line accident, a power transmission line anomaly approaching alarm system was developed to automatically alarm the operators and surveillants. The surveillance system, composed of camera, surveillance unit proper and alarm receiving portion, generates alarm and indicate hazard to the operators, when animal invades a hazardous area designated on the monitor. Wireless telegraph for the alarm transmission use used frequency around a 322MHz band with the Radio Ray law and preventive measures from noise, taken into consideration. The prototype is characterized by unnecessary ancillary fitting to the surveillance object, rare erroneous operations and high reliability. While the hazardous area can be simply designated, changed and released, as made by volume on the control panel. It is moreover easy to designate, as done by confirming the surveillance object on the display. It is also possible in multidimensional surveillance and easy to use on site. 7 figs.

    A survey was made in relation with joint utilization of welfare device development data using an international network. Developing welfare devices requires data from ergonomic and medical systems, while the cope of the objects is wide, and the kinds are various. For proliferation of welfare devices, system compatibility evaluation including that on using environment is important, including living environments that are different by countries. The present survey has identified how data for aged, handicapped and help-needing persons are accumulated and utilized in research organizations in America and Europe for both of the ergonomic and medical areas. The survey also investigated major academic societies in overseas countries, and collected database and academic network information that support the advanced research and development. At the same time, investigations were also made on organizations and corporations who are moving forward the efficient data utilization. Welfare device and service information providing systems in Japan were investigated to compare them with the trends in other countries. Conceptions and methods were compiled to utilize data internationally and jointly. Database models for device development were considered, and a proposal was made on structuring a research and development supporting database, and the operation method thereof. (NEDO)
