    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.

    It may be intended that CWM is manufactured in areas near coal producing areas in overseas countries and imported as a product requiring lower handling cost than in bulk products. In order to achieve this idea, it is necessary to establish a distribution and relaying system for product transportation inside and outside the country, including relaying bases for receiving, loading and storing the product. This paper reports results of the demonstration tests performed since 1992 to 1996. In the tests, CWM made from Chinese coals was transported from Shijiu Port to the Hibiki relaying base in the city of Kita-Kyushu on 5000 DWT ocean vessels, unloaded, stored, and loaded again on 700 DWT domestic vessels for distribution to users. Since the inauguration of transportations, 40,000 tons of CWM were delivered yearly to the Okayama plant of Tayca Company, and about 20,000 tons to the Mizushima power plant of the Chubu Electric Power Company over a period from 1995 to 1996. During the period, a number of findings were acquired in different aspects, including quality control of incoming and outgoing CWM, stability in quantity and properties, loading and unloading works, and transportation. Although reduction in subsidence during transportation and storage was indicated desirable, the practical applicability was verified for the relaying system as a whole. 4 refs., 15 figs., 3 tabs.

    Discussions were given for the purpose of realizing automation of facility operation and automatic monitoring of facilities by using optical electronics technologies in underground power transmission facilities. In sensing technologies using optic fibers, an optic fiber distribution type sensor was found suitable for monitoring underground power transmission lines as a sensor to measure temperature distribution and pressure distribution along the optic fibers. In sensor signal transmission technologies using optic fibers, laying ultra-high voltage transmission lines over a distance of several ten kilometers is becoming used generally in underground transmission paths, with the environmental requirements on electromagnetic fields becoming more stringent. Under these restraints, an optical transmission system is more advantageous that has longer-distance and wider-area transmission capabilities, and high-insulation and non-induction performances. In technologies to lay optic fiber cables in underground cable paths, contrivances are given on the cable construction for cases where optic fibers and power cables, each varying in mechanical strength are to be integrated. 151 refs., 155 figs., 30 tabs.

    Interconnecting photovoltaic systems with power transmission systems under high density affects power quality, protection, maintenance and stability of the transmission lines. As measures to deal with this issue, investigations are being made on (1) elucidation of effects imposed on transmission lines, (2) establishment of countermeasure technologies, and (3) technological options leading to higher value addition. In Item (1), with an objective to identify the current status, evaluations were given on prevention of independent operation of commercially available inverters, and on their stabilizing performance against system fluctuation. The evaluations were performed by conducting a test for multiple unit operation in parallel and a single unit performance test. The test result indicated that, while the prevention performance can be satisfied, maloperation has occurred frequently due to the system fluctuation, and that voltage rise due to the inverter was suppressed effectively by using the simultaneous control of active and reactive powers. In Item (2), a demonstration test was launched on an inverter incorporating a new prevention device. The effective means to suppress voltage rise in the high-voltage power transmission lines is the discrete voltage suppression by controlling reactive power. In addition, a proposal was made on a new voltage and phase detection method that can be used at short circuit of the high-voltage transmission lines. In Item (3), having a photovoltaic system contain a small size batteries was found effective in suppressing the power generation output variation, and in smoothing the loads. (NEDO)

The Physical Modeling System is 10,000 times smaller than the real one, comprising a water tub section, measuring device section, and control section, etc. The water tub section comprises a tub for housing the model, transducers for transmitting and receiving vibration, controllers, etc. The water tub measures 1.8{times}1.2{times}0.9m. The model used in the experiment is an `inclined multilayer model` with each of its six layers pinching out toward the top, and is usable for the comparison of various migration methods. In one case in the records, reception was made at 184 reception points deployed at intervals of 3mm, when the minimum offset was 15mm and the maximum offset 564mm. Nothing very obvious was observed when the ordinary overlapping of DMO and CDP was applied to this record, which suggests that pre-overlapping migration treatment is required. 5 figs.

    Safety measures and assessment technology were studied for the WE-NET project. As the study result in fiscal 1996, the information on safety design, anomaly and accident was collected and arranged. The information on safety measures, ideology and criterion was also collected by visiting some domestic and overseas organizations experienced about handling of liquid hydrogen (LH). The initial survey was made for the safety design ideology, analytical technique and disaster preventive measures of LNG systems as the similar cold liquid system. Accidents and explosion accident of a hydrogen production plant (water electrolysis) in Germany were analyzed. Events on storage tanks and leakage around the tanks were studied as typical risk of LH considering temporary and LNG system design information. The model based on the LH spillage test result and 3-D dispersion of vapor cloud were prepared by modifying a simulation code. The model allowed evaluation of the effect of explosion and fire accidents of compressed hydrogen gas and flying fragments on structures and people, and visual display of distances from a tank and damage conditions. 19 refs., 29 figs., 18 tabs.

    Equipment which made experiments on air conditioning and hydroponic cultivation possible was set up at the technical research center of the Chugoku Electric Power Co., to study an air conditioning system using night power and energy saving technology for the cultivation. Vegetables suitable to the cultivation were selected. For air conditioning, adopted was a water heat storage air conditioning system using night power. The space between the shade curtain and the greenhouse roof was ventilated to prevent increase in cooling load caused by rise in curtain temperature. Moreover, the cultivation equipment was covered with transparent vinyl film to cool the inside of the equipment. The hydroponic cultivation equipment was trially manufactured which makes the continued production by one worker possible. The cultivation of spinach, leaf lettuce and chingensai throughout the year became possible. The yield of chingensai reached the target, but those of spinach and leaf lettuce were approximately 70% of the targets. Vegetables to be produced in the air-conditioned greenhouse by hydroponic cultivation are thought to be those that can have added values such non-pesticides and ingredients, young plants which were increased by cutting or tissue culturing, etc. 5 refs., 19 figs., 8 tabs.

    The aim is to develop a method of processing oxygen concentration distribution in human organs into an image by computed tomography using near infrared rays capable of transmitting through living tissues. Since the photoabsorption spectra of hemoglobin etc. in blood vary according to the degree of their oxidation, an oxygen concentration level is determined by measuring the magnitude of the variation. In the imaging method named in the title, the object is irradiated with picosecond-level near infrared pulses from all directions successively, the pulses after transmission through the object are measured at all directions at a picosecond-level time resolution, and the distribution of pulse scattering and absorption characteristics are subjected to algorithmic calculation, the outcome is converted into oxygen concentration levels, and an image is obtained. A 64-channel time resolution measurement system is constructed, and is applied to living tissue models (phantoms) and animals, and an image is obtained and evaluated. On the basis of the result, a patient is examined for clinical evaluation, and an image reflecting the distribution of variations in hemoglobin oxygen concentration is obtained for the head of the adult patient. A spatial resolution of 1cm is achieved in case of a phantom 10cm in diameter. In the case of 64 channels, measurement takes approximately 20 minutes and mapping image data measurement takes approximately 7 minutes. (NEDO)

    The solar energy utilizing technologies having been developed under the Sunshine Project were used to have executed the international joint technology development on the 'solar heat utilizing drying system' in the Republic of Indonesia. This paper summarizes the achievements in fiscal 1998. In operating the pilot plant, three operational experiments out of seven experiments were carried out only by Indonesian engineers. As a result of the drying experiments, the heat collecting characteristics of the collector were as about half at 19 to 30% as the efficiency assumed in the design of 50%. The reason for this can be attributed to the fact that the cover glass used in the demonstration test in Japan had light permeability of about 87%, but the cover glass used in the test plant was made of frosted glass whose light permeability was about 37%. This glass is the only glass available for a heat collector in the solar heat hot water device in Indonesia, but is unsuitable for the heat collector. Another cause was that the insolation at the site was lower by about 30% than the one used at the design stage. (NEDO)

    The goal is to develop basic technologies to build an SiC device capable of service amid high-temperature surroundings for the advancement and optimization of combustion control systems. In an SiC semiconductor, the Si-C bond is broken when irradiated with ions, and this makes the occurrence of thermal oxidation easy to occur. In the study to form SiC into single-crystal substrates, a substrate with warpage of 10 micrometers or less and surface coarseness of 10 nanometers or less is realized. In the development of sensor technologies, the high-speed CVD (chemical vapor deposition) method is applied for the growth of crystals further on a 3C-SiC layer epitaxially grown by MBE (molecular beam epitaxy) surface control, which improves on layer characteristics. Element technologies are developed for the construction of a 3-terminal element (FET: field effect transistor), which is for the construction of a high-temperature, high-speed SiC device. An effort is made at achieving 3C-SiC hetero-epitaxial growth, etc., on a 3-inch Si substrate using an SiC crystal film formation experimenting apparatus, which aims at constructing a control device. Concerning the combustion control system, the relations between the air/fuel ratio and the emission spectra of radicals OH, CH, and C2 in a flame are made clear.

    From the sonic prospecting on the ground, it was confirmed that faults distributed in the inner part of Suruga Bay extend near the Fujigawa river mouth. While, faults in the sea bottom were found by the sonic prospecting using a single air-gun. However, continuity of faults running from the land to the sea has not been reported. This paper describes the continuity of Fujigawa fault system running from the land to the sea around Fujigawa river mouth along the subduction zone of Philippine Sea Plate using single air-gun seismic reflection records. Locations of the faults can be expressed as fracture information of linearment obtained from the satellite remote sensing images, which agreed well with those found by the Active Fault Research Association. As a result of the image processing, they agreed distinctly with the topography of Fujigawa fault system. Thus, much more accurate analysis can be performed by comparing the regional information by the remote sensing with the sonic seismic reflection profiles. 3 refs., 2 figs.

    The efforts center on techniques for optimizing the designing process of the system-on-chip (SoC) which assumes the most important part in the technology involved. An SoC is a system in which most of the system-constituting functions are integrated on a single chip, whose design is growing increasingly difficult to prepare because its circuitry containing complicated functions is growing larger in scale at an annual rate of 58%. Its elements are growing microstructural at a sharp pace, and a very optimum designing technique is required to deal with the development. Under the circumstances, the numbers of engineers and man-hours required to cope with the situation are increasing exponentially. The improvement of design productivity at the present time stays at a low annual rate of 21%. Surveyed are the background, objective, and necessity of the research and development of technologies for the whole designing process consisting of the function designing stage which is of the highest level, the logical circuit designing stage, and the manufacturing process designing stage. Furthermore, the current status, research, and development of related technologies and the status of related patents in Japan and overseas are surveyed. Studies are also conducted about the goals of technologies to be developed and about breakthrough points before achieving the goals, and a development project is assumed and proposed. (NEDO)

    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.

    In relation to the conceptual design of the total system of hydrogen utilization, the paper described the fiscal 1997 result. The study was conducted having no relation with the conventionally assumed large-scaled/centralized utilization based on the hydrogen produced from renewable energy. Costs of coal gasification and natural gas reforming hydrogen production become lower than that of the hydrogen from the hydroelectric power utilization overseas. However, the processing of CO2 fixation is at a developmental stage, and it is required to see and watch it in the future including the time of the commercialization and economical efficiency. Further, the hydrogen recovered from industrial complexes has a possibility of becoming sources for the distributed utilization (hydrogen diesels, fuel cells, and hydrogen cars). The pipeline transportation of hydrogen gas via the East China Sea from China can be expected. The CO2 emission unit requirement of the power system by liquid hydrogen transportation/ammonia transportation is equal to that of the renewable energy power system and low in environmental loads. The unit requirement of the methanol transportation power generation, in which coal is used, is the same as that of the LNG fueled power generation and inferior in environmental characteristics. The combination with the CO2 fixation processing technology is indispensable. 25 refs., 53 figs., 60 tabs.

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

    Practical application of subsurface crack characterization by the borehole radar measurement to which the radar polarimetric method was introduced was attempted to measuring objects for which the borehole radar has not been much used, for example, the inside of low loss rock mass or fracture zone where cracks tightly exist. A system was trially manufactured which makes the radar polarimetric measurement possible in the borehole at a 1000m depth and with a about 10cm diameter, and a field experiment was conducted for realizing the subsurface crack characterization near the Nojima fault. For the measuring experiment by the polarimetric borehole radar, used were Iwaya borehole and Hirabayashi borehole drilled in the north of Awaji-shima, Hyogo-ken. In a comparison of both polarization systems of Hirabayashi borehole, reflected waves at depths of 1038m and 1047m are relatively stronger in both polarization systems than those with the same polarization form and at different depths, whereas reflected waves around a 1017m depth are strong only as to the parallel polarization system. Characteristics of the polarization in this experiment indirectly reflect crack structures. 6 refs., 6 figs., 1 tab.

    An airborne gamma-ray survey was carried out to investigate the active fault system in the central structure line in the peripheral area of the city of Wakayama. At the same time, with an objective to enhance applicability of the airborne gamma-ray survey to active fault investigation, fundamental data were acquired and discussed. The measurement data were processed according to the standard method specified by IAEA. An ID-FFT filter and a nonlinear filter were employed to extract anomalous gamma-ray intensity values. The gamma-ray intensity distribution chart shows a noticeable positive anomalous area extending from the central part of the western edge to the north-east direction. This area agrees nearly well with the Negoro fault, but its peak portion is positioned slightly more to south than the position of the Negoro fault shown in existing data. The Sakuraike fault and the vicinity of the central structure line also show positive anomaly as a whole, particularly remarkably in the vicinity of their converging portion. However, differing from the vicinity of the Negoro fault, the areas are not extracted as an anomalous area which has directionality and extends in a line form. One of the factors for this would be that it is a fault in unsolidified deposits with low opening trend, differing from the one in solidified rocks. 1 fig., 3 tabs.

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

    Survey has been conducted to develop laser processing technology utilizing the interaction between substance and photon. This is a part of the leading research on photon technology development. The photon technology development is aimed at novel technology development highly utilizing the quantum nature of photons. In the field of laser processing, high quality photons are used as tools, special functions of atoms and molecules will be discovered, and processing for functional fabrication (photon machining) will be established. A role of laser processing in industries has become significant, which is currently spreading not only into cutting and welding of materials and scalpels but also into such a special field as ultrafine processing of materials. The spreading is sometimes obstructed due to the difficulty of procurement of suitable machines and materials, and the increase of cost. The purpose of this study is to develop the optimal laser technology, to elucidate the interaction between substance and photon, and to develop the laser system and the transmission and regulation systems which realize the optimal conditions. 387 refs., 115 figs., 25 tabs.

    This paper summarizes the text of the research result report in the separate volume II-1 from among the fiscal 1998 report on the achievement made on researching and developing a molten carbonate fuel cell (MCFC) power generation system. For the AC-DC type system whose high performance and large capacity stacks are being developed, detail designs were made on 250-kW class stack module assembly and installation procedure. At the same time, processing and forming were continued on such main components as electrodes, electrolyte plates and separators. The cells were assembled as modules, sintered, installed and adjusted. Aids were given by the process and control (PAC) test on devices and piping of the fuel cell system block. Cell life extension is also under study. For the parallel flow type stack, two 250-kW stacks were fabricated, and an overall adjustment test was begun thereon in March. For the reformer, an internal reforming system was developed for the 200-kW class system, whose adjustment test is scheduled for April 1999. Capacity increase is also under discussion. For practical use of MCFC, stack life of 40,000 hours is said required. The current status is at the level of exceeding 10,000 hours, but the necessity is seen in suppressing voltage drop associated with lapse of time. (NEDO)

    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)

    Research and development has been performed on a system technology for the human cooperating and coexisting type robot that can perform various types of works substituting human hands. This paper summarizes the achievements in fiscal 1999. In developing a high-function hand, development and fabrication were executed on a device to teach four finger holding actions that correspond to the enhancement in action stability and control responsiveness of the four finger hand and to positions and attitudes of objects. In fabricating the robot platforms, single platform tests and remotely controlled platform connection tests were performed, which demonstrated the functions as an integrated system. In developing libraries for topography adaptive three-dimensional basic walking actions, development was carried out on libraries that correspond to menus for direct advance on a flat land, slewing, and walking on staircases and irregular land. It was found that control closer to that for actually usable robot is possible by considering time delay in articulate control when simulation was performed using the testing robot body. In the study and survey of robot proliferation, development plans were presented that take into consideration the social influence, technological factors, and cost need adaptability. (NEDO)

    This paper describes the achievements in fiscal 2000 from the development of candidate low-temperature materials for liquid hydrogen transportation and storage (including mother materials and welds) for WE-NET. Evaluation tests were performed on material properties (mechanical properties, low-temperature embrittlement, and hydrogen embrittlement sensitivity) under room temperature and low temperature regions including liquid hydrogen atmosphere. Low temperature toughness of welds was assessed particularly to identify characteristics of different welding methods developed newly for improvements. The stainless steels and the mother materials of aluminum alloy selected as the candidates have sufficient characteristics even under the liquid hydrogen atmosphere, but the welds have lower low-temperature toughness, requiring improvement. For the stainless steels, since the amount of {delta} ferrite in welds affects greatly the low-temperature toughness, adoption of complete austenite type welding metal is effective. The reduced pressure electron beam welding method can enhance drastically the low-temperature toughness of stainless steel. For the aluminum alloy, it can be one of the alternatives to use an alloy system with composition of high low-temperature toughness. The friction stir welding method for the aluminum alloy was found to provide extremely high low-temperature toughness, which can be evaluated as a new welding method. (NEDO)

    Studies were conducted to find out hydrogen absorbing alloys with an effective hydrogen absorption rate of 3 mass % or more, hydrogen discharge temperature of 100 degrees C or lower, hydrogen absorbing capacity after 5,000 cycles not less than 90% of the initial capacity, applicable to stationary and mobile systems. The V-based alloy that achieved an effective hydrogen absorption rate of 2.6 mass % in the preceding fiscal year was subjected to studies relating to safety and durability. Since V is costly, efforts were exerted to develop TiCrMo alloys to replace the V-based alloy. In the search for novel high-performance alloys, endeavors centered on novel ternary alloys, novel alloys based on Mg and Ti, and novel intermetallic compounds of the Mg-4 family. In the study of guidelines for developing next-generation high-performance alloys, methods for creating hydrides with an H/M (hydrogen/metal) ratio far higher than 2 were discussed. Mentioned as techniques to produce such hydrides were the utilization of the hole regulated lattice, novel alloys based on the ultrahigh pressure hydride phase, new substances making use of the cooperative phenomenon in the coexistent multiple-phase structure, and the like.

    Atmospheric concentration of CO2 is increasing, and discussions are urged on measures to suppress emission of CO2 into atmosphere. While different CO2 fixing technologies may be conceived, there is a technology to utilize CO2 absorbing capability of ocean by discharging and dissolving CO2 artificially into middle layer of the ocean to separate CO2 from atmosphere. This technology is one of the technologies which are promising in the aspects of technology, economic performance, and possible amount of CO2 reduction. However, it is difficult to say that scientific and technological discussions have been given sufficiently on behavior of CO2 discharged into the ocean, effect of the discharge on environments, and CO2 separation capability of the ocean. Therefore, in the present research and development, a 'technology to forecast environmental effect in areas in the vicinity of CO2 discharging points' is developed to serve for acquiring technological prospect on the feasibility to realize the CO2 ocean separation by discharging CO2 into the middle layer of the ocean. The present fiscal year has performed researches on the following research and development items: elucidation of behavior of liquefied CO2 when discharged into the ocean, CO2 feeding and diluting technologies, indoor experiments on the effects of CO2 on ocean living organisms, and development of a model to forecast environments in areas in the vicinity of CO2 discharging points.

    To evaluate geothermal reservoirs in the initial stage of development and keep stable output in service operation, the application of MEMS is under development. This paper describes the result in fiscal 1997. Installation of 3-component velocity type seismometers in bore holes is desirable for permanent monitoring sites. Their arrangement should be determined by detection ability simulation. Their locations at various elevations are effective to improve the accuracy of hypocenter determination. Digital seismic data at the permanent sites are transmitted to a center through cables, while temporary data are recorded on site. For poor MEPAS, a Windows program of basic functions was developed. 3-D seismic velocity analysis and array monitoring system were also studied. A P-wave velocity of rocks decreased by 25% by formed two-phase region, and increased by 10% by decrease in reservoir temperature from 200 to 100degC. The velocity can be detected by change in travel time of direct waves due to considerable variation in reservoir environment. VSP technique using a vibrator or air gun as artificial hypocenter is effective for MEMS. 67 refs., 64 figs., 19 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)

    As a realistic measure to reduce environmental pollutants emitted from coal-fueled boilers, a developmental study was conducted of high-efficient combustion systems. In fiscal 1994, four types of topping cycles which are different in system structure and gasifier type were selected, and topping cycles assuming a 300MW-class power plant were trially designed. Further, an evaluation of adaptability of these systems was made, and an selection of the optimum system for the early development was made among the systems. As a result, the evaluation was obtained that `a system using air blown gasifier` is most suitable for conducting the next-stage research. In the element test on the topping combustion technology, collection was made of data of desulfurization activity, desulfurization oxidation mechanism and alkali metal behavior at the laboratory level, data of temperatures and gas concentration distribution in coal gasification, data of simulation of the gasifier reaction, and the other data. 262 figs., 66 tabs.

    The purpose of the project in FY 1998 is 'Experimental verification for EV spread promotion.' Two of a 3-month experiment were conducted in Yokohama MM21 area (Yokohama, Kanagawa) and in Tama Newtown (Inage, Tokyo) using a total of 100 (50 each) small EVs. The development was aimed at of an urban type rental-car system in Yokohama and of a car-sharing type second-car system for residential in Inage. As to these responses to ITS technology, the basic vehicle operation system was made common in both areas, and the daily use system was made a regional system considered of purposes of use, regional characteristics, etc. The experimental verification was worked on as almost expected in terms of the vehicle management, monitor assessment, responses from persons concerned in both areas. Therefore, it is said that the R and D have almost reached a point where there can be seen a possibility of system commercialization. Through the experimental verification, the development was able to be smoothly promoted of the basic technology and element technology which are thought to be needed for the commercialization of EV. From the experience of this experimental verification, it is judged that it is desirable to tackle the commercialization by a membership system when the commercialization of EV joint use system is planned in future.

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

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

    The energy saving environment-friendly technology for low- grade difficult-to-process ores was researched focusing attention on the hydro-metallurgical process of non-ferrous metals. This research aims at development of both effective leaching system of metals, and separation/crystallization system recognizing the property difference between metal ions in solution. The leaching system allows the inexpensive molecular level control of electron transfer, mass transfer of metal ions and stabilization of leached metal ions in a solid/liquid interface. The system thus allows selective leaching of metals from various resources such as difficult- to-leach sulfide minerals to prepare concentrated solutions. The separation system can obtain high-purity solutions including each metal ion by advanced separation/concentration technology from the solutions. The crystallization technology (including electrolysis) is developed for preparing target metal materials by molecular level control of nucleation, particle growth, thin film formation and bulky metal formation processes. Overall energy consumption is reduced to 1/3 of that of the pyro-metallurgical method, aiming at zero emission. 15 refs., 14 figs., 11 tabs.

    Sintering technology has evolved steadily in the last decade by upgrading specifications of apparatus around the sinter strand and by the sophisticated process control methods. In order to use much difficult-to-sinter raw material without decreases of productivity and product yield and also deterioration of quality, new types of granulation systems for control of mineral constitution formation, such as HPS (Hybrid Pelletized Sinter) Process, CaO Selective Pregranulation Process and Self-Densificication and High-Melting-Point Liquid-Phase Sintering Process, have been developed and installed successfully. Increased productivity has been achieved through improving product yield and permeability in sintering bed by the development of new types of raw mixture feeder, such as ISF (Intensified Sifting Feeder) etc., and by the technology of homogeneous sintering both horizontally and vertically in the bed, such as SECOS (Sintering Energy Control System) etc. In addition, older and less efficient sintering machines are closed, converging on large-scale and small number machines which in turn renewed process control system based on artificial intelligence and introduced high-efficient and compact environmental systems as replace of old ones. Eventually, the major improvements have been achieved in four items: (1) increase use of cheap raw materials such as limonite ore and pellet feed. (2) Reduce production costs by productivity increase, with high product-yield and by man power saving. (3) Upgrade sinter quality in slag volume and reducibility for acceleration of PCI injection to blast furnace. (4) Reduce environmental impact with use of high efficient apparatus. 66 refs., 9 figs., 2 tabs.

    Various energy-related issues were analyzed in a many-sided and compound manner; and as their solutions, various combined systems were examined on the assumption that functional mediums, core technology and regional district characteristics were utilized; and an explanation was given in the case of using hydrogen as an energy medium. Hydrogen was a strong candidate capable of securing toughness in energy flow; and an idea was shaped about introducing hydrogen by steps before structuring a hydrogen society that is to replace the petroleum society. In the case of introducing a hydrogen energy medium into an intelligent building, the characteristics would be such that it is a highly efficient system capable of supplying energy in the form of electric power, hydrogen and heat, that it brings in a function for leveling a load of electric power, that it facilitates consistency with each energy in various uses, and that it is capable of dealing with a demand for hydrogen energy which is expected to increase in the future. It is highly probable that the system will become an attractive one in view of environment and social economy. 8 refs., 4 figs.

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

    As carbon dioxide-related environmental measures, method was explained to chemically convert and utilize carbon dioxide. Synthesis is possible of methanol, carbon monoxide, different carbohydrates, etc. by catalytic hydrogenation of carbon dioxide, using hydrogen produced by the electrolysis of water. Task consists of heightening in both convertibility and selectivity, and abundant supply of low cost hydrogen. Methane, alcohol, etc. can be synthesized by electrochemical reducion of carbon dioxide. Because of effectively inserting multiple electron, discssion is being made of catalyst, intergrated with electrode, and electron transmitter. The photoelectrochemical reduction of carbon dioxide can be also made by utilizing photoelectric current, generated upon photoradiation on the semiconductive electrode. However, task consists of heightening in both efficiency and selectivity. Photochemical reduction of carbon dioxide, actually made by green plant, consists of oxidationlike decomposition of water and reduction of carbon dioxide. Both those reactions are skillfully separated by intermediation of very quick electron transmission system. Reduction is being studied with semiconductor, metallic colloid, enzyme, metallic complex and other various catalysts. 10 refs., 3 figs., 4 tabs.

The result of the development was described paying attention to column flotation which is a technology to high-efficiently select particulate regions, particulate heavy media cyclone, magnetic separation, and the basic design of the process into which those above were integrated. The two-stage selection process, which is an integration of column flotation and particulate heavy media cyclone into the conventional coal preparation equipment, can produce low-ash clean coal at high separation efficiency and also suppress the rise in processing cost. This process was also effective for removal of sulfur content and trace metal elements. The use of clean coal at power plant can be effective for not only the reduction in ash treatment amount, but the aspect of boiler operation characteristics such as heat transfer efficiency of boiler furnace wall, ash related troubles, loads of electrostatic precipitator, loads of flue gas desulfurization facilities. 17 figs., 5 tabs.

    The coal partial combustor (CPC) uses a combustion technology with which coal is burned at elevated temperatures and under revolution, the constituents are captured on the furnace wall and removed as molten slag from the furnace. This is a combustion technology to reduce load of ash on subsequent devices. To generate a molten condition, it is necessary to raise the combustion temperature as high as possible (to about 1600 degC in the furnace), but this is effective for a gas turbine composite power generation system. An efficiency of higher than 45% may be expected at the power transmission terminal. As an operation on subsidy from the Agency of Natural Resources and Energy, the normal-pressure CPC technology has already been established, and a research on pressurized CPC is being progressed since fiscal 1991. The research is in progress with a schedule that elemental tests for 7 tons per day production are conducted until fiscal 1995, a 25 tons per day pilot plant will be completed by November 1997, and verification tests for long-term continuous operation will be implemented until 1998. The 7 tons per day elemental tests have identified gasification performance and slag extraction performance using five types of coal having different properties. 7 refs., 10 figs., 4 tabs.

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

    The research and development project is implemented for production of low-cost, large-area modules of CdTe solar cells by the high-quality film-making process and high-function patterning, and the FY 1999 results are reported. The research program for the large-area TCO film-making technologies involves investigations on improvement of SnO{sub 2} film quality by the mist method and continuous film-making, which lead to continuous, stable production of 34 substrates of low resistance of 9.7{omega} on the average. The program for production of the large-area, thin-film CdS/CdTe solar cells involves production of TCO and CdS by the mist method, and patterning of the laminated TCO/CdS film by laser scribing. The CdTe film is formed by the atmospheric pressure CSS method, and treated with CdCl{sub 2} to improve its crystallinity. The CdTe film is patterned by sand blasting, and provided with the carbon and silver electrodes by screen printing, to complete the cell. The process is totally effected at the atmospheric pressure, needing no vacuum device. The CdTe solar cell assembly (130 cells connected in series, opening area: 5,413cm{sup 2}), fabricated on a trial basis, achieves a conversion efficiency of 10%. (NEDO)

    With an objective to improve efficiency and reduce cost of CIS-based thin film solar cells, research and development has been made on technologies to increase high-quality CIS film area and technologies to increase speed in the manufacturing process. This paper describes the achievements attained during fiscal 1997. The research covered development of technologies to form high-grade Cu (In, Ga) Se{sub 2} (CIGS) film by using the multi-dimensional deposition process, component technologies for forming a rear electrode, a buffer layer and a transparent electrode, and patterning technologies. As a result of the research, thickness of the CIGS film was reduced to half as much as that of the conventional films, having achieved conversion efficiency of 13.1%, which corresponds to about 90% of the conventional CIGS solar cells. In addition, elucidation was made on the effect of an MoSe{sub 2} layer existing on interface with CIGS/Mo in a CIGS solar cell imposed on solar cell characteristics. In developing an Mo film laser scribing technology, intensity dependence of laser energy was made clear, the energy being required for scribing according to surface condition of the Mo film. (NEDO)

    A polycrystalline Si thin film formation technology is developed, which uses the flux process in which a reaction occurs between the target crystal and a flux component which is eutectic. Using this process, a crystal grain relatively large in diameter is obtained at a relatively low temperature. This method is now attracting attention as one of the technologies for producing crystalline Si film for use in thin-film polycrystalline Si solar cells. Especially when Al is used for flux, since Al is automatically doped into the target crystalline Si film, it is expected that the resulting film will serve as the ground for a photoactive layer provided with the BSF (back surface field) function which is important for the improvement of solar cell efficiency. A polycrystalline Si thin film is formed on a 2cm times 2cm-large glass substrate at a temperature not higher than 600 degrees C. It is recognized that films selectively oriented towards the (111) or (100) plane are acquired when other processes are employed. It is expected that the said Al-doped film provides a ground on which a BSF function-provided photoactive layer will be formed. (NEDO)

    Development will be made on high-performance a-solar cells as part of developing practical application technology for a-solar cells for electric power use. Development will be also made on a low-cost process technology. This paper describes the achievements attained during fiscal 1997. Quality improvement has been realized by using a high RF power hydrogen dilution process on a-Si films for front cells of lamination type cells. Four times faster film forming speed was obtained even by using the VHF plasma CVD process, with film quality equivalent to those made by using the conventional RF process maintained. By optimizing the light enclosing construction, the short circuit current was enhanced by over 20%. Discussions were given on forming homogenous a-Si films by optimizing the conditions for forming films on large-area substrates, which resulted in forming film of 30 cm times 40 cm size with good homogeneity at a film forming speed three times faster than the conventional speed. A surface electrode was formed successfully with good uniformity on a substrate with a size of 60 cm times 90 cm. Productivity greater by over three times the conventional productivity was achieved in patterning of transparent electrodes by using high-output laser. Simultaneous and collective patterning and very small and long size collective patterning were realized in a-Si film selection patterning by using the plasma CVD process. (NEDO)

    The target is a low-cost CdS/CdTe solar cell of a large area (60cm times 90cm), the establishment of mass-production technologies for the cell, and the enhancement of production efficiency. A thin film formation technology of subjecting CdS film organic metal to pyrolysis is established, which reduces photoabsorption loss in the shortwave domain of wavelength of not longer than 500nm, reduces reflection loss in the film, and improves on short-circuit current density. Improvement is also achieved on CdTe film quality and junction quality by use of a proximity sublimation method in a vacuum, when a conversion rate of 16.0% (1cm{sup 2}) is attained which is the highest in the world. Based on the results of the above-said efforts, a 3.3mm-thick glass substrate is employed for CdTe film to develop into a 30cm times 60cm-large size, with the film thereon uniformly thick over a large area thanks to a normal pressure proximity sublimation method. Studies are made toward a process nearer to the ultimate product and, using the patterning technique, a 30cm times 60cm-large CdTe solar cell is tentatively built realizing a conversion rate of 9.8%.

    This paper reports the result obtained during fiscal 1994 on research on a technology of low temperature deposition of polycrystalline thin films for solar cells. This research used ITO coated glass substrates, on which CdS was accumulated to a thickness of about 100 nm by using the CBD process, and over this deposition a CuInSe2 film was formed at 300{degree}C by using the ion cluster beam (ICB) process. The manufactured solar cells with a glass/ITO/CdS/CuInSe2/Au structure had an efficiency of 2%. In manufacturing a CuGaSe2 thin film by using the ICB process, effects of acceleration voltage relative to cluster beams and ionization current were investigated. It was found that the film morphology, the result of analysis by using X-ray diffraction, and the electric conductivity are sensitive to the ionization current. From these findings, an optimum film forming condition was derived. A CuGaSe2 thin film was manufactured by using the ICB process over a Cds thin film deposited by using the CDB process. Both of the surface morphology and X-ray diffraction patterns of the film did not show a large change, indicating a possibility of manufacturing cells with a reverse structure. Effects of heat treatment on CuInSe2 monocrystals were evaluated by using ESR and FTIR. 6 figs., 1 tab.

    It is urgently necessary for the Philippines, which has no promising energy source to replace imported oil and lacks hard currencies, to reduce dependence on oil. The country, consisting of a number of islands, has faced many difficulties in construction of large-scale power transmission grids covering wide areas, which greatly retard development of local industries and dissemination of electricity.

    This paper introduces a metallocene catalyst and syndiotactic PP synthesized therefrom. The metallocene catalyst discovered in 1980 is a combination of metallocene compound of the IV-family transition metal with methyl aluminoxane (MAO) as a promoter. The metallocene catalyst has its active species homogeneous and soluble to solvents, hence it is called a homogeneous-system polymerized catalyst. Further, its active species concentration is said to account for 65% or higher of the transition metal at normal temperatures, and has high polymerization activity and superior random copolymerization performance. A syndiotactic PP having high stereoregularity and macromolecules sufficient in amount as molding resin was synthesized in 1988 by using a combination of the metallocene catalyst with MAO. It has properties of crystallinity from 30% to 40%, a melting point in a range from 140[degree]C to 150[degree]C, and a density of 0.88. It has high normal-temperature impact strength, low bending elastic modulus, and high transparency, and is expected to develop into foodstuff and medical material packaging materials. 4 figs., 3 tabs.

    Regulations, conventions and agreements relating to the discharging liquefied carbon dioxide (CO2) into the bathypelagic zone from a cruising ships are investigated. The ocean storage of CO2 is not specifically prohibited by law, but must be regulated on a global scale because such treatment may impact the marine environment. In principle, treatment with impact on the nature is prohibited. Laws of environmental conservation are completed in European, Asian, and Pacific countries, which join international conventions and committees with high interests. It is suggested that the engineering technique of the storage should be improved to observe regulations and that an impact assessment for the ocean storage should be carefully conducted in full understanding of the basic premise of the regulatory systems or organizations. Furthermore, it is significant to study on the possible effect of the ocean storage of CO2 on global warming and life-cycle assessment inventory analysis, namely the balance of the energy budget between the separation and the ocean storage of CO2. 23 refs., 7 figs., 6 tabs.

    In order to utilize more effectively coal ash whose generation amount is increasing year after year, studies have been made on a technology to manufacture and utilize a high-strength substance solidified under normal temperature by utilizing hydration reaction of pozzolan system (Poz-O-Tec). The study works have been done as a subsidy operation of the Agency of Natural Resources and Energy, and were completed in fiscal 1995. Poz-O-Tec is a wet powder made of coal ash and stack gas desulfurization sludge (gypsum) added and mixed with lime and an adequate amount of water, which solidifies by hydration as pozzolan does. The same method as used for ordinary sands may be used as the basic application method. Because this is the material whose strength increases after construction, thickness of construction may be reduced smaller than in constructions using soils and sands. Test constructions of about sixty cases have been carried out to date, typically represented in use as a road bed material, banking, and a base material for water-barrier gutters. High-strength solid material which is stable under normal temperature may be obtained by adjusting calcium content. As a result of its effectiveness in practical use having been verified, a certificate of technological judgment has been issued for the material by the Civil Engineering Research Center. 3 refs., 11 figs., 2 tabs.

(1) On development of epitaxial growth technology of lattice mismatching systems, the optimum structure of InGaAs strain intermediate layers was studied for reducing a dislocation density by lattice mismatching of GaAs layer grown on Si substrate and difference in thermal expansion coefficient. The effect of strain layer on dislocation reduction was found only at 250dyne/cm in strain energy. Growth of GaAs layers on the Si substrate treated by hydrofluoric acid at low temperature was attempted by MBE method. As a dislocation distribution was controlled by laying different atoms at hetero-interface, the dislocation density of growing layer surfaces decreased by concentration of dislocation at hetero-interface.

    It is intended to develop thin film solar cells capable of mass production with high photo-stability and at low cost. Thus, the objective of the present research is to analyze the growth process of micro crystal silicon based thin films, the crystal being a high quality silicon crystal based material, and develop technology to manufacture high-quality micro crystal silicon thin films based on the findings therefrom. It was found that, when silicon source is available in cathode, pure hydrogen plasma forms micro crystal silicon films by using the plasma as a result of the chemical transportation effect from the silicon source. It was revealed that the crystal formation due to hydrogen plasma exposure is performed substantially by the crystals forming the films due to the chemical transportation effect, rather than crystallization in the vicinity of the surface. The crystal formation under this experiment was concluded that the formation takes place during film growth accompanied by diffusion of film forming precursors on the surface on which the film grows. According to the result obtained so far, the most important issue in the future is particularly the control of crystal growing azimuth by reducing the initially formed amorphous layer by controlling the stress in the initial phase for film formation, and by controlling the film forming precursors.

    As a WE-NET subtask, a study has been conducted of the solid polyelectrolyte water electrolysis method by which higher efficiency and lower cost hydrogen production is expected than in the conventional hydrogen production method. Production methods of electrode, electrolyte, etc. were studied. In the electroless plating method, the manufacturing process of membrane-electrode assemblies was realized in a large area of 2500 cm{sup 2} by the porous-surfaced method by studying manufacturing conditions for slurry membrane/membrane assembly/electroless plating processes. In the hot-press method, the refining degree and dispersibility of iridium dioxide powder were studied to improve characteristics of anode catalyst. A method was developed to form polyelectrolyte coatings homogeneously on the surface of electrode layer catalytic powder, and a large area of 2500 cm{sup 2} was realized. Beside the performance test using large single cells, FS was conducted to discuss optimum operating conditions and optimum structures of plants. Both methods indicated the performance exceeding the energy conversion efficiency of 90%, a WE-NET target, at current density of 1A/cm{sup 2} and electrolysis temperature of 80degC. A key was found to a bench-scale development (electrode area of 2500 cm{sup 2}, about 5 layers) to be planned in fiscal 1998. 136 figs., 50 tabs.

    Research and development was made for the purpose of achieving by the end of fiscal 2000 conversion efficiency of 30% or higher in a 5-cm square tandem solar cell using hypercomplex compound semiconductors, and establishing a new low-cost cell structure. In developing a large area cell manufacturing technology, a totally organic MOCVD process was used for epitaxial growth for forming the cell structure in manufacturing a 2.5-cm square GaInP single junction cell. Conversion efficiency of 13.1% was attained, but this is still insufficient as the conversion efficiency for a top cell. In the epitaxial growth in the GaAs cell structure, conversion efficiency as good as 22.1% was obtained. Also for a GaInAs cell being a bottom cell, a 2.5-cm square cell was fabricated on a trial basis. When a GaAs/GaAs laminated cell is formed by using the mechanical stacking method, the conversion efficiency has risen to 27.5% in total, thus having nearly achieved the goal for fiscal 1997. Fundamental discussion has begun on epitaxial growth of GaInNAs and nitride mixed crystal, which has a possibility as a new bottom cell material. (NEDO)

    For the research and development of erosion-resistant abradable materials for the methane-fueled aircraft engine front section, a laser-aided surface reform technology was developed for Ti alloys and the like. In relation with the article 'Intermetallic Compound Coating Formation Technology,' an NiTi sprayed coating containing excess Ni solid solution was found to be quite high in resistance to erosion, and similar to Ti-6Al-4V in resistance to oxidation at 300 degrees C. Furthermore, an MCrAlY erosion-resistant coating was formed capable of resisting oxidation at temperatures higher than 1000 degrees C. In relation with the article 'Spraying Phenomenon Evaluation Technology,' studies were made of combustion synthesis reaction during plasma spraying and of the prediction of flight trajectories of different powders, for which optical fiber dichroic temperature measuring, 2-dimensional imaging, and LDV (laser Doppler velocimetry) were applied in combination. Concerning the spraying of intermetallic compound coatings, a temperature rise occurred when heating by laser was performed simultaneously with the laser-induced combustion synthesis reaction. In relation with the article 'Technology of Multiple Spraying on Curved Substrate,' it was found that the gas cooled method works effectively when spraying an erosion-resistant coating onto a thin Ti alloy made turbine blade.

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

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

    The effort of fiscal 1997 at isolating the best way to introduce a relatively small amount of hydrogen into urban fuel economy was carried over to fiscal 1998. In the research of fiscal 1998, comparison was made between Tokyo and London in connection with hydrogen introduction, and a transition scenario was proposed for introducing hydrogen into Tokyo. Models were built for Tokyo and London, and studied. The result of this study was different from that obtained in the previous study, and places the two cities under similar conditions. The difference is attributed to the rapid progress in the development of the fuel cell and to the resultant reduction in cost. It is inferred that, in consideration of the transportation situation, the introduction of pure hydrogen will be the most cost-effective for both cities at least for some time to come. According to the revised data, natural gas may be procured in Tokyo as in London but the size of supply available in Tokyo is fairly smaller than that in London. Several transition scenarios covering the period up to 2025 were subjected to discussion. (NEDO)

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

    A study was made for the purpose of electrification of unelectrified zones of the mountainous areas in developing countries using extremely small hydroelectric power facilities. The target for this project is a development of a micro hydroelectric power system with a size of about 5kW, which is estimated regarding that 1 village has 80 houses and each house needs electricity of 60W. In the study, the low-head system using a weir of irrigation channels in Subang pref. of West Java state was selected by the evaluation of access, stability of flow rate, natural conditions, etc. The hydroelectric power plant is of a flow-in method in which water is taken from the left bank and is injected/discharged to the downstream of the left bank. As the hybrid complementary power source, hybrid battery with a two-hour charging time at peak and a capacity of 3.5kWh was considered. When estimating the construction cost of the hybrid micro hydroelectric power system and equalizing by durable years, the operational cost per kW is 15 times higher than the benefits which local people receive. It was judged to be difficult to say that the micro hydroelectric power system is economically feasible. It was predicted that the financial profit during the demonstrative test is good, according to a trial calculation of income from power rates and the operational cost. 18 refs., 90 figs., 53 tabs.

    This paper describes discharge excitation technology and resonator technology as basic technologies for high power CO2 lasers. As a result of progress in high-frequency power element techniques, the discharge excitation technology now generally uses laser excitation using AC discharge of capacity coupling type. Its representative example is silent discharge (SD) excitation. This is a system to excite laser by applying high voltages with as high frequency as 100 kHz to 1 MHz across a pair of electrodes covered with a dielectric material. The system maintains stability in discharge even if power supply voltage amplitude is modulated, and easily provides pulse outputs. Discharge excitation for diffusion cooled type CO2 laser generates a discharge in a gap with a gap length of about 2 mm, and can perform gas cooling by means of thermal conduction of gas, whereas a compact resonator can be fabricated. A resonator for the diffusion cooled type CO2 laser eliminates gas circulation and cooling systems, hence the device can be made more compact. A report has been given that several of these compact resonators were combined, from which a laser output of 85W was obtained by using RF discharge of 2kW. 43 refs., 21 figs.

    A simplified method is developed, which measures dioxins in flue gas without using GC/MS (gas chromatography/mass spectrometry) of the double focusing type. The sampling device is built of two collecting bottles, containing water and diethylene glycol, and uses no XAD-2 (cross-linked amberlight divinyl benzene) resin. Such a design does not need time consuming Soxlet extraction in the sampling process and shortens the processing time. An HPLC (high performance liquid chromatography) system replaces the convenient column chromatography system in the cleanup process, and this enables automation and rapid treatment. For the measurement of toxicity equivalent, GC/MS is used to separate and quantify 17 kinds of toxic isomers as in the conventional method. The GC/MS is of the quadruple focusing type, however, and this reduces the device cost at the initial stage and shortens the time for operators to acquire the skills of maintenance and operation. Though the quadruple focusing type is inferior to the double focusing type in sensitivity, the shortcoming is compensated for by massive specimen injection using a PTV (programmable temperature vaporizer). The result of a JIS (Japanese Industrial Standard) method and the result of this newly developed method are found to agree excellently with each other. This method is simple and efficient, suitable for use in the analysis of small incinerator flue gas. (NEDO)

    This paper describes a prospect of French industrial technology research and development under President Chirac`s political power. The research and development in France is characterized by the national leadership. It depends greatly on the system and organization as well as the economical factors. The policy concentrates on the reformation of development organization rather than the research and development itself. It is required to provide the cultural and social tradition and environment that can bring up people bearing it, the system that can supply the methods of research and development, and the force of technology and market development that can industrialize and commercialize its results. The national leadership in France basically relates to all of these three factors. The actors of framework for the financing and enforcement of research and development are illustrated in a scheme by dividing them into government and companies. The actors for the enforcement of research and development are also divided into governmental public organizations and companies. This paper also provides the defense development in the private companies having a large finance of research and development from the government. The finance of research and development for public welfare from the government is roughly divided into the large-scale projects with determined usage by the government, and the supports for proposals by the companies. 13 refs., 4 figs., 40 tabs.

    As a part of the WE-NET project, the introduction condition of hydrogen as substituting energy and CO2 reduction effect were analyzed using a global energy model. The WE-NET project aims at global-wide introduction of clean energy by converting abundant renewable clean energy into hydrogen transportable to distant consumers all over the world. The study result in fiscal 1996 is as follows. Undeveloped hydroelectric resources in the world are estimated to be 12 trillion kWh/y equivalent to the existing developed one in the world. Since the cost of the hydroelectric power generation projects over 1000MW in the planning stage is estimated to be 0.02-0.05$/kWh lower than that of other renewable energies, such projects are expected as energy source in the initial stage of the practical WE-NET project. The GREEN model was modified by adding a hydrogen analysis function, and extending an analysis period. The modified model allowed evaluation of the long-term important role of hydrogen energy, in particular, the capability of CO2 gas reduction all over the world. 28 refs., 92 figs., 56 tabs.

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

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.

    This paper reports the achievements in fiscal 2000 in development of a technology to evaluate reliability of petroleum refining facilities. The development efforts were made mainly on analyses by simulation and neural net (NN) that utilize computers. In the high-temperature system facilities, the creep damage generation is governed by different factors including impurities. The evaluation on joint life requires simultaneous use of low temperature zone long-time test. Verification was made on application of non-destructive inspection, such as use of ultrasonic waves in the accelerated creep zone. Defect detecting capability was identified when an ultrasonic wave flaw detection model is used for buried piping. In the pulse eddy current flaw detection, a coil most superb in totality was selected by means of simulation, by which corrosion and wall thickness of piping and devices were detected from outside the sheathing materials. Development was made on a technology to diagnose and evaluate corrosion of tank in operation by using the AE method.

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

    A technology is developed to perform high-efficiency power generation by generating high-temperature and high-pressure steam stably by burning general wastes and combustible industrial wastes as fuel. This paper describes summary of the achievements in fiscal 1998. Corrosion tests were performed on over-heater materials under steam condition of 500 degrees C and 100 kg/cm{sup 2} by using a hot model. It was verified by the tests that the corrosion environment around an external heat exchanger is milder than that with an external stack. A circulation fluid bed was simulated from operation data, and a prospect was obtained on steam conditions required for the high-efficiency power generation. In order to elucidate the corrosion mechanism, discussions were given on deposited ash properties, corrosion characteristics and stress. Elucidation was made on a discharge chamber structure most suitable for removing dioxins and NOx by using a waste gas treatment process that uses plasma generated by discharge. A concept design was made. The economic effect of the system is equivalent to that of the activated carbon blow-in process, whereas a waste gas treatment system was nearly completed. As a result of the pilot plant test, the power generation efficiency is estimated to be 30% in a scale of 1200 tons per 24 hours. A demonstration test revealed that dioxin emission was far below the regulation value. An optimal system was also discussed. (NEDO)

    The achievements during fiscal 1993 of research and development on a method to evaluate warm heat comfort by living scenes of workers by using a human body thermal model included completion of a human thermal model introduced with physiological knowledge such as artery-vein anastomosed (AVA) blood vessels and two-system blood circulation net. The effectiveness of the model was experimented and verified. It was made possible to estimate the reversal phenomenon occurring in hot heat environment, in which skin temperatures at peripheral body parts rise higher than those in the body trunk part, and skin temperature distribution. In the correlation study to estimate statistically the sense volume from skin temperatures, it was possible to estimate significantly different sense volumes from face skin temperatures, but the estimation accuracy was low because of such factors as difference in individuals. What is important in enhancing the accuracy is to identify ecological reactions of human being caused from change in the sense volume, select effective parameters, and study the mechanisms. In order to develop stress relaxing scents, discussions were given on degree of subjectivity stress by question papers and cortisol concentration in saliva as the parameters. An experimental system was developed to measure the effects of the scents to relax work stresses. A screening method was developed, whereas effects of 15 kinds of scent materials were investigated.

In evaluating the warm heat comfort by living scenes of workers according to the human body thermal model, the research environment was improved by expanding the systems to measure physiological volume and the warm heat environment. Findings were acquired on the relationship between body fat rate and skin temperature, and actions of artery-vein anastomosed (AVA) blood vessels. These findings were incorporated into the research to elevate the levels of applicability of the human body thermal model. In estimating the sense volume by using skin temperatures, physiological volume being the factor of variation in face skin temperatures was elucidated, and a system to measure these variations was structured. In order to acquire the physiological volume being the factor of variation in face skin temperatures, brain wave topography measurement and {alpha} frequency fluctuation and arousal evaluation and measurement were experimented, where the effectiveness thereof was verified. Analysis was also made on blood flow rate and perspiration volume related to skin temperature variation mechanism, which has provided a number of fundamental data.

    The paper arranged the present situation and the problems of environmental cooperation for developing countries, and studied based thereon how to cooperate in environmental protection for developing countries in the future. At the same time, it arranged the problems/subjects posed when environment-related companies in Japan try to transfer environmental technology to developing countries, for the purpose of using them as data in studying possibility of reviewing the environmental cooperation presently conducted. A view on environmental cooperation is that as security of mankind, it is necessary to help developing countries in technology/knowledge/fund. However, a trial calculation indicated that the initial investment of 11.1 trillion yen is needed only for desulfurization and water treatment in China and ASEAN countries. Such a huge amount of money cannot be paid at all even by developed countries. As the support of environmental protection measures, the one also including energy and resource is needed. Further, the support of environmental protection measures should be the one that has the exhibition effect and influential effect, promotes efforts of developing countries' own, and pushes independent environmental measures forward. From this point of view, a study was made on what the details of the environmental cooperation should be like. (NEDO)

    Discussions were given on a sterilizing effect of ozone on Fusarium bacteria in hydroponic culture, and its effect on components in the culture solution. In an experiment, dry air with O3 concentration of 3.5 ppm was sent into aqueous solution inoculated with Fusarium bacteria at a flow rate of 5 liters per minute. The Fusarium bacteria was sterilized nearly completely in about five minutes. No change was observed in pH, EC and dissolved oxygen concentration of the O3-treated culture solution. However, iron and manganese among the soluble components have been oxidized by O3 and precipitated, hence these components must be added after the O3 treatment. In spinach culture performed on a culture medium inoculated with Fusarium bacteria, ozone water containing dissolved O3 at 0.8 ppm was flown into a urethane foam medium and vegetable roots. This treatment has resulted in reduction of the number of strains occurred with a wilt symptom below that in the section flown with distilled water. The spinach has grown normally without showing an effect of the ozone water. 15 refs., 10 figs., 3 tabs.

    Described herein are the FY 1998 results of the activities for development of extraction and production technologies for the deep-seated geothermal resources, which are expected to contribute to increased geothermal power generation capacity. The program for the PTSD logging technology connects the S probe to PT probe, to simultaneously measure temperature, pressure and volumetric flow, producing the data of good quality even in a high temperature environment over 327 degrees C. Thus, possibility of the commercial system is confirmed. The D probe also produces a density calibration curve showing very good linearity, and operates normally in a high temperature environment of 406 degrees C. The program for the PTC monitoring technology conducts the field tests at Larderello, Italy, to confirm the sampler functions in a high temperature environment.

    During ultrafine structure formation due to transformation from austenite to ferrite in an intense magnetic field, the transformation is accelerated by the thermodynamic stabilization of the ferrite phase which is ferromagnetic. The application of an intense magnetic field works effectively during the generation of nuclei. When a magnetic field is applied during reverse transformation, a honeycomb 2-phase structure is formed oriented toward the direction of the magnetic field and, when the structure is vertically compressed, the recrystallized structure is made ultrafine effectively. In pearlite transformation, hardening occurs when carbon atoms supersaturated in density are introduced in the presence of a magnetic field gradient, and curing further promotes precipitation hardening. In a ferrite complex phase system, wherein ultrafine globular cementite is uniformly distributed, plastic instability becomes explicit in a tensile test. There is a good possibility that an ultrafine structure recrystallization model may be built by calculation, into which the distribution of energy stored prior to recrystallizing nucleus formation is incorporated. The profile of a conceptual process of off-line or in-line integration of heavy-strain process and intense magnetic field application has become tangible. (NEDO)

    In the fiscal 1995 study, items were searched which are keys to the design of a liquid hydrogen tanker of a capacity of 200,000m{sup 3}. Among those, the basic concepts were summarized which are necessary for the design of a liquid hydrogen tanker in terms of safety, and the extraporation of the existing low temperature technology into the large liquid hydrogen tank was studied. When adopting safety conditions of IGC Code applied to LNG to the liquid hydrogen tanker, it is necessary to limit the discharge amount of hydrogen to 3 kg/s. When considering safety at fire, for keeping safety of the same level as that of the LNG tanker, it is not appropriate to adopt the conventional vacuum insulation liquid hydrogen tank. In the fiscal 1995 study, 7 kinds of concept of the insulation structure were assumed, and it was concluded that BOR of 0.04-0.23/d was obtained. Also in fiscal 1996, the large liquid hydrogen tank was studied. For insulation of the large liquid hydrogen tank, the structure is most promising where AEROSIL bag or homogeneous AEROSIL is substituted for a forming heat insulating material of 4 design, but further study is needed for selection of the optimum heat insulating structure. 9 figs., 6 tabs.

    Full Text Available A nonlinear robust control-system design framework predicated on a hierarchical switching controller architecture parameterized over a set of moving nominal system equilibria is developed. Specifically, using equilibria-dependent Lyapunov functions, a hierarchical nonlinear robust control strategy is developed that robustly stabilizes a given nonlinear system over a prescribed range of system uncertainty by robustly stabilizing a collection of nonlinear controlled uncertain subsystems. The robust switching nonlinear controller architecture is designed based on a generalized (lower semicontinuous Lyapunov function obtained by minimizing a potential function over a given switching set induced by the parameterized nominal system equilibria. The proposed framework robustly stabilizes a compact positively invariant set of a given nonlinear uncertain dynamical system with structured parametric uncertainty. Finally, the efficacy of the proposed approach is demonstrated on a jet engine propulsion control problem with uncertain pressure-flow map data.

If {Yj,   j=1,2,…} are independent indentically distributed random variables independent of S, then the system S′={{YjXnj,j=1,2,…,kn}} is obtained by randomizing the scale parameters in S according to the distribution of Y1. We give sufficient conditions on the distribution of Y in terms of an index of convergence of S, to insure that centered sums from S′ be convergent. If such sums converge to a distribution determined by (γ′,(σ′2,Λ, then the exact relationship between (γ,σ2,M and (γ′,(σ′2,Λ is established. Also investigated is when limit distributions from S and S′ are of the same type, and conditions insuring products of random variables belong to the domain of attraction of a stable law.

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

    For the enhancement of separation process efficiency and energy efficiency in the chemical industry, etc., basic technologies are developed involving high-performance separation membrane materials which are excellent in durability and usable in the field where separation by membranes has been impractical. The liquid mixtures subjected to separation are a neutral organic compound/water system, an acidic organic compound/water system, and a polar organic compound/water system; the gas mixtures subjected to separation are an oxygen/nitrogen system and a carbon monoxide/nitrogen system. After a 10-year/3-phase development endeavors, the initially intended goals are sufficiently achieved. Among those that have to be mentioned is the development of a nonaqueous separation membrane, a supported liquid membrane with amino acid optically active high performance separation capability, a high-precision evaluation unit for gas separation membrane characteristics, a selective permeation membrane with high-level oxygen and carbon monoxide carriers and reactivation technology, a high-performance ethanol separation membrane, a water/polar organic compound separation membrane, and a water/acetic acid separation membrane and stability providing technology.

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

    The compressed air energy storage gas turbine power generation system is paid attetion to as a load levelling power source in view of the recent increase in electric power demand. The paper describes features, cavern construction technology, economy and future expansion of the system. In this system compressed air made by use of cheap night-time electric power is stored in underground spaces or underwater facilities. Burning the fuel together with this compressed air in the daytime, the gas turbine power generation is conducted. Several examples overseas of this system are reported including a 290,000KW class in Germany. A key technology of the system is how safely and cheaply a large amount of hih-pressure air can be stored. In Europe and America, caverns of hundreds of thousand m {sub 3} are constructed in the rock salt cavern which can be excavated by a water jet. In consideration of storing it in rock beds in Japan where there are no rock salt caverns, NEDO started 1990 a 9-year construction plan of a 35,000 KW class pilot plant at Kamisunagawa, Hokkaido. 2 refs., 5 figs., 1 tab.

    This report describes follow-up for research and development on the recovery of valuable resources, such as magnesium, bromine and boron, contained in the brackish water for manufacture of common salt in the coastal region of Mexico. For the field survey, salt garden, irrigation plant and manufacturing plant of dinning salt were inspected. The optimum site was examined by assuming desalination plant and solar pond. The groundwater in coastal regions is progressively salified. Since the coastal region is a tourist resort with an round-trip area of whales, environmental protection is indispensable. For the joint research with invited researchers, the solar pond system and fresh water generation were studied. As a result, it was found that the solar pond system is an excellent method for keeping thermal energy in a low cost at the salt garden with abundant solar energy, and that the desalination system combined with distilling is the most suitable method. 7 refs., 8 figs., 1 tab.

    Behavior of neural networks relative to noise and the constitution of an optimum network are studied for the construction of a 3-D MT data interpretation system using neural networks. In the study, the relationship is examined between the noise level of educational data and the noise level of the neural network to be constructed. After examination it is found that the neural network is effective in interpreting data whose noise level is the same as that of educational data; it cannot correctly interpret data that it has not met in the educational stage even if such data is free of noise; that the optimum number of neurons in a hidden layer is approximately 40 in a network architecture using the current system; and that the neuron gain function enhances recognition capability when a logistic function is used in the hidden layer and a linear function is used in the output layer. 2 refs., 7 figs., 2 tabs.

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

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

    In Japan with its rapidly aging society, fundamental technologies are required for the development of artificial nerves substituting for or supporting damaged ones, and ultimately constituting artificial neurons based on the knowledge of the brain functions at the molecular and cellular levels. This study defines the fundamental technologies which would be required for the development in the area, and further, evaluates the potential of the technologies to develop the novel industry. The brain function is closely related to the activity in neuronal circuits. In order to repair injured nerves and to develop the advanced technologies of electronics for helping impaired neuronal functions, the most important and urgent is to understand how to work the neuronal circuit system in the brain. Based on these viewpoints, new methodological approaches would make it possible to relieve neural impairment in the sensory input system and the motor system by the use of electronic circuits. They also would improve rehabilitation after injury, and treat neurodegenerative diseases such as Parkinson`s disease. These advances surely create the new types of industry seeds in near future. 77 refs., 29 figs., 2 tabs.

    The International Symposium `98 on the industrial waste problem in the Asian region was held in Tokyo on February 18, 1998. MITI commented on the present situation of the industrial waste problem in Japan and Japan`s environmental tackling toward the Asian region, and also Asian countries (China, the Philippines, Thailand and Korea) made reports. Japan reported on environmental preservation measures taken in the industrial circle, the industrial waste problem at companies which advanced into Asian countries, effects of the Basel Convention (which restricts border-crossing movement of harmful wastes) on recycle activities, Japan`s role in Asia, etc. In the panel discussion, discussions were made on human interchange in the informatization, recycling technology, shortage of personnel concerned with environmental protection, construction of a network in the Asian region and Japan` s role, etc. As to the treatment system for waste, the necessity was recognized of studying systems which meet with actual states of each country. It is also necessary to go on with discussing how the system should be for cooperation between governments and private companies. Importance of the recycle and information exchange was emphasized. 10 refs., 14 figs., 27 tabs.

    For the river structures, such as slice gates and slice pipes, constructed on the weak ground, structures often come out due to forced settlement of embankment, which results in the formation of cavity and loose ground. These deformations can cause disasters due to leakage by water channel and fracture of bank. It is significant to detect and grasp these situations in early stage. In this study, resistivity imaging was conducted around slice gate in several times, to estimate the loose region based on the difference in the obtained resistivity data. Resistivity was measured in two times with a certain interval using the same line. The loose region around the slice gate was estimated from the change of saturation condition and the saturation line by considering the difference. Even in the case when judgment was hard by a single measurement, it was possible to estimate the loose region based on the difference from multiple measurements. 3 refs., 6 figs.

    The numerical analysis program based on the difference method for dynamics of sea water with sea-surface displacement, flow rate, salt content and temperature as the parameters is modified to more accurately assess the effects of a huge marine structure on surrounding environment by adding the effects of insolation and boundary conditions of the sea-covering effects of the floating structure. The numerical simulation was done for summer and winter seasons, not in a sea area but using a rectangular bay with the floating structure at the center. A new flow evolves around the floating structure, due to the sea-covering effect. The flow patterns in summer and winter are clearly different, due to difference in insolation. The predicted flow is also sensitive whether stratification is considered or not, by which is meant that it is important what stratification effect is taken into account. Daily insolation changes are accompanied by vertical distribution of water temperature and its temporal change. These effects are also observed under the floating structure which shields insolation. 10 refs., 17 figs., 4 tabs.

    Various surveys were conducted for the area around the Nojima fault, including ground surface, two-dimensional electrical and boring surveys and elastic wave tomography, in order to grasp properties of the ground around the `Nojima earthquake fault.` The resistivity image method as one of the two-dimensional electrical methods was used to grasp fault shapes over a wide range of the 1.6km long section extending between Esaki and Hirabayashi. The courses of traverse were set in the direction almost perpendicular to the fault. Boreholes were excavated and elastic wave tomography was conducted between the boreholes on the 9th and 17th courses of traverse, to confirm ground/mountain conditions and to compare the results with observed elastic wave velocities. Very low resistivities are observed at places where granite is distributed, suggesting that the fault-induced changes are not limited to the area around the fault. The zone in which elastic wave velocity decreases is narrow, 10m at the longest, at a velocity of 2.4km/s or lower, which is a low velocity for that propagating in granite. 5 refs., 4 figs.

    The development and utilization of new energy and reusable energy in China have greatly progressed for these 20 years, but it is necessary to further enhance the rate of these energy in the energy structure by heightening the conversion efficiency and reducing the production cost. As to the matured technology, it is necessary to attempt a large scale modernization and form a completed production/service system by making large breakthrough of new technology/new industrial art. For improvement of levels of a lot of new energy technology, emphasis should be placed on international cooperation, R and D, and model business. Together with the introduction of reusable energy such as photovoltaic, wind, geothermal and ocean power, the conventional low efficiency biomass utilization system is converted one after another. The development/spread of clean coal technology are promoted, and the rate of the hydroelectric/atomic power generation is heightened. By 2010, the full-scale application/spread of new energy technology should be advanced, and the technology and production of the world top level should be realized. It is necessary to make the energy consumption clean and promote the continuously harmonized growth of economy, society and environment. (NEDO)

    This paper describes an advanced transverse thickness profile control method of thin hard steel strips at tandem cold rolling mill in the Mizushima Works of Kawasaki Steel Corporation. The work roll profile was optimized by the profile control of cold rolling using a one-side tapered work roll sifting method, to expand the profile control range in transverse direction of steel strip. Based on the data measured by the profile meter set at outlet of hot roll mill, the work roll sifting position can be controlled in response to the size of hot-rolled strip crown. A feed-forward edge drop control system and a feed-back edge control system using an edge drop sensor set at outlet of mill were established. Consequently, high thickness accuracy in transverse direction was achieved within 0.5% in a steady rolling state and within 0.8% in a non-steady rolling state over the full length of the thin hard steel strip product. 14 refs., 15 figs., 2 tabs.

    Described herein are the FY 1998 research and development results of solid electrolyte fuel cells. For R and D of the tubular type cell by the wet processing technique, the tests are conducted to evaluate the initial performance and long-term durability for continuous operation of the single tubular cell. For development of the several-kW class modules, computer-aided simulations are conducted. For R and D of material and substrate techniques, the thermal cycle characteristics, cell characteristics and stress of the cell modules are evaluated, in order to evaluate their reliability. The thermal cycle test results indicate that performance of the single-stage cell is unaffected by the thermal cycles. It is found by the stress evaluation that use of the separator plate having a higher thermal expansion coefficient than the electrolyte plate and use of the sealant having a thermal expansion coefficient close to that of the electrolyte plate are effective means to reduce stresses. For the research to reduce costs of the cell materials, their chemical, mechanical and thermal characteristics are evaluated. For the system research, the areas for which the compact systems are suitable and their optimization are studied. (NEDO)

    Element techniques were studied and surveyed for establishing the technology of integrated coal gasification combined cycle. In fiscal 1995, E coal (coal of high ash fluid point) gasification was tested in the 2 tons/day furnace for the effect of its properties on furnace operation and for its properties relating to gasification and slagging and for changes in such properties due to flux admixed with the E coal. It was then found that the ash fluid point was so high as 1500 degrees C and that flux admixing, recovered oxygen reinjection, etc., would be necessary for the assurance of stable slag discharge. In a study using combined cycle system simulation, a comparison was made between results from tests conducted on a real system and results from the simulation, based on the detailed model completed by the preceding fiscal year. The model was reviewed and improved, and simulations were conducted in the respective operating states and operating modes. In the survey of element techniques, information was gathered at a Japan-U.S. joint technical conference held in Japan in October this year.

    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)

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

    The aim is to create inorganic materials with their functions well harmonized and with their reliability remarkably improved, and efforts are made to establish basic technologies with which structural control may be carried out simultaneously for multiple layers in in-process products through positive utilization of various chemical reactions in the materials synthesizing process. This fiscal year's achievements are stated below. A low-temperature pressure nitriding method is developed in which nitriding reaction directly involves the metal aluminum compact for conversion into ceramics, and an aluminum sintered body is produced capable of high thermal conduction of not less than 170w/mk with the original compact shape retained. By a heat treatment in a high-temperature pressure nitriding atmosphere, a success is attained in producing a silicon nitride ceramic body enhanced (150w/mk) in thermal conduction. It is clarified that the microwave-aided selective heating technology works effectively in enhancing the particle growth rate in a liquid-phase sinter system, and a success is won in increasing strength by virtue of the formation of particle-growing particles.

    Efforts continue from the previous fiscal year to analyze time-dependent correlations between changes in fatigue/alertness-related psychological quantities and combined physiological changes. Using an office space as a sample, an augmented model is completed concerning a relative method of measurement, analysis of impression structure, scaling of the degree, and simultaneous relationship analysis. The environmental compatibility indexing is improved by analyzing physical quantities and brain waves that influence psychological sensation. In the indexing of product compatibility wherein the compatibility between products and human beings is evaluated from the viewpoint of affinity or friendliness, the index structure dependent on subjectivity and physiological reaction is enhanced in precision. Application case studies in which indices of physiological sensation, environments, and product compatibility are reflected on the designs of daily-use products and living/working circumstances, and a human sensory database prototype is experimentally constructed. The indexing prototype, related to muscular fatigue due to a restrained working attitude and mental fatigue due to the load of mental activities, is enhanced in precision. In the study of product compatibility indexing technology, improvement and evaluation are carried out on the practical attitude/sight line evaluation system. (NEDO)

    With an objective to select a promising process by comparing application environments and effectiveness of a high-temperature carbon dioxide separation, recovery and re-utilization technology with other methods, investigations were performed on reducible amount of carbon dioxide discharge by using material balance and system introduction. A large number of chemical and physical technologies are being developed for the separation and refining methods. This paper discusses the technologies for their application to iron and steel making, oil refining, and petrochemical industries, the so-called heavy and large product industries. As a possibility of utilizing the high-temperature separated CO2 in iron and steel making, an investigation was given on the direct iron ore smelting reduction process. It would be unreasonable to use CO2 in oil refining as a substitute to air to regenerate a catalytic decomposition and reformation catalyst because of decline in the catalytic activity. A discussion was given on a case to replace steam with CO2 in steam reformation and pyrolysis of hydrocarbons. The discussion requires the objective to be focused on such items as C/H ratio at a reformer outlet and relationship of balance in decomposition products. The C1 chemical and others were reviewed to search possibilities for their use as raw materials of chemicals used in chemical industries. Possibilities were discussed to fix high-temperature CO2 into peridotite and serpentine. 42 refs., 32 figs., 11 tabs.

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

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

    With an objective of establishing the coal gasification composite power generation technology, R and D has been carried out on the elementary technologies. This paper summarizes the achievements in fiscal 1994. In the research on the large gas turbine combustor for the demonstration plant, combustion tests were carried out by using the actual gas from the designed coal (coal D). In addition, the minimum gas flow rate test, fuel calory change test, and fuel switching test were performed from the viewpoint of evaluating the low load stability. Furthermore, in order to evaluate the combustion performance of the tested combustor, such tests were conducted as the combustor pressure loss characteristics test, bypass valve flow rate characteristics test, light oil ignition and light oil combustion test, and tests on the characteristics to switch from light oil to coal gas and the coal gas combustion characteristics. Evaluations were given on the NOx conversion rate, CO, THC, combustion efficiency, metal temperatures, pattern factors, pressure loss, internal pressure variation, and vibration stress. In the simulation research of the composite power generation system, the simulation models were varied according to the actual plant requirements in association with the progress of the tests on the pilot plant. The results of the simulations were reflected to the general load pressure control equipment. (NEDO)

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

    This paper describes the result of a pilot experiment on biological treatment, ozonization, and activated carbon treatment as high-level water supply treating technologies. In biological treatment using a biological contact filtration method, the nitration rate of NH4-N was maintained at 90% or higher even during the low water temperature period, the chlorine demand in the treated water remained at near 2 mg/l or less, and the average removal rate reached 87%. In preozonization, general bacteria were removed at a rate of 99.5% at an ozone injection rate of 2.0 mg/l. Attaining a removal rate of 80% in Geosmin and 2-methyl isoborneol (2MIB), the musty odor substances, required the ozone injection rate of 1.6 mg/l and 1.8 mg/l, respectively. The activated carbon treatment used the coal-based activated carbon (AC-1) and the charcoal-based activated carbon (AC-2). Both activated carbons removed Geosmin at more than 98% and 2MIB at more than 94%. The removal rate for trihalomethane formation potential was 62% in the AC-1, and 46% in the AC-2. The AC-1 was superior to the AC-2 also in removing organic matters and totally organic chlorine compounds. 8 refs., 7 figs., 1 tab.

    This paper describes a new bubble-cleaning dissolved oxygen analyzer with improved maintainability as a sewage water quality measuring instrument, and a sludge activity measuring instrument to measure new water quality control items for managing and controlling microorganisms. The bubble-cleaning dissolved oxygen analyzer uses a tip-detecting polarographic electrode, and has excellent maintainability because of its bubble cleaning mechanism. Since output rise resulted from the bubble cleaning is as very small as about 0.2 mg/l, continuous cleaning is possible while a measurement is continued. The continuous cleaning provides high cleaning effect because microorganism film deposition can be prevented constantly. The sludge activity measuring instrument measures automatically adenosine triphosphate (ATP) to evaluate activities in microorganisms quickly and accurately. The ATP measurement utilizes organismic luminous reaction, and performs the measurement automatically from the sample extraction to the luminous measurement by simply fractioning the test samples into test tubes. The instrument can also estimate using ATP such biomasses as MLVSS and BOD, of which measurement consumes a large amount of time. 2 refs., 3 figs., 1 tab.

    This paper describes attempts of establishing an oil recovery technology utilizing microorganisms and of aiming at improving the practicability of that technology. Fiscal 1994 has investigated effects of inorganic salts existing in reservoir beds and NaCl concentrations on proliferation of microorganisms and production of metabolites. The investigation was intended to discuss applicability of microorganisms to environments that are brought closer to actual field conditions. Furthermore, a core sweeping test using sandstone was carried out on the fiscal 1992 separated bacteria, the 4118 bacteria, that has high surfactant production capability. In addition, a sand pack was used to perform a flooding experiment under conditions of 50{degree}C and 50 KSC to evaluate functionality of microorganisms when environments in the reservoir bed are simulated with respect to pressures and temperatures. An oil recovering experiment was carried out using a sandstone with a diameter of 1.5 inches, a length of 1.0 foot and permeability of 600 md, and using Bacillus subtilis 4118 bacteria which attained the lowest interfacial tension among the bacteria examined. A recovery rate of 4.4% Sor was derived in the experiment. A recovery rate of 29.0% Sor at maximum was obtained when Bacillus licheniformis 18-2-a bacteria was supplied into a sand pack filled with silica sand. 20 figs., 7 tabs.

    Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

    In waterjet machining, a high-velocity waterjet is released from a nozzle 0.1-2.0mm in diameter at a speed approximately equal to or higher than the sonic speed, and the energy of the jet is applied to machining processes such as cleaning, peeling, boring, and cutting. The pressure domain in which waterjet is now in practical use ranges widely from several MPa to 400MPa, and waterjet is used in all the fields of industry. In this report, waterjet machining is outlined, and waterjet machining technologies are described. Devices for generating waterjet include turbine pumps, plunger pumps, intensifiers, and impact pressure units. In the machining process, it is inferred, dynamic pressure, pulsating load, impact force of water mass, cavitation phenomenon, and water wedge effect coordinate with each other in complicated ways for the achievement of a synergistic effect, and this causes and accelerates the phenomenon of destruction. Machining is divided, in terms of use and purpose, into the cutting technology, cleaning technology, and technologies utilizing high pressure itself. (NEDO)

    Summarized herein are the materials designs/production and tests/evaluation results of heat-resistant materials, i.e., alloys, ceramic composites and carbon-based composites, which are expected to be applicable to the hydrogen combustion turbines. These have been studied since 1993, and this paper summarizes the overall evaluation results of the phase I program. The intermetallic compound as one of the candidate materials has a high-temperature strength in a range from 1200 to 1400 degrees C by optimizing elements added. However, no prospect is obtained for heat resistance at 1700 degrees C or more for the material not coated or cooled moderately. Each of the other candidate materials tested shows a bright prospect of applicability at the base material and specimen levels. The single-crystal superalloy for hybrid cooling structures has novelty in that it is free of Cr but incorporated with Si and Hf, showing approximately 10 degrees C higher heat-resistant temperature than CMSX-4. CMC and C/C are inherently excellent heat-resistant materials, and are attractive advanced composites, because they are expected to realize no-cooled blades at 1700 degrees C. (NEDO)

    Current technologies are surveyed and tasks to discharge are extracted relating to heat resistant alloys, intermetallic compounds, ceramic based composite materials, and carbon based composite materials, which are expected to be used for hydrogen combustion turbines. Concerning oxide dispersion strengthened alloys for cooled vanes, tasks to discharge are extracted, which relate to the designing, development, and selection of vane materials, bonding layer materials, and coating materials, and to thermal barrier coating techniques and machining techniques. Concerning porous fiber reinforced ceramic materials for ceramic shells, tasks involve the elucidation of corrosion behavior and manufacturing techniques. MoSi{sub 2}, which is a promising high-melting intermetallic compound, also presents some tasks to discharge for an increase in its high strength and high ductility in an ultrahigh-temperature steam/reducing atmosphere, and for improvement in manufacturing techniques. For the carbon/carbon composite material which is the sole material usable in the ultrahigh-temperature domain of 2,000 degrees C, an analysis and evaluation method taking its anisotropy into consideration needs to be developed, and an oxidation resistant coating has to be also developed. In addition to the designing and development of these materials, development is necessary of materials testing and evaluating techniques. (NEDO)

    This report refers, continuously to the Part 1, to the in-situ verification test of the slow-response type model machine rotor and to the review of the conceptual design of the pilot machine. On the basis of the R and D results of various element technology/partial models obtained before the previous fiscal year, the design, manufacturing and factory test had been conducted for a 70,000kW class slow-response type model machine rotor. This year, an in-situ verification test was performed to complete the test of all planned test items. Using the technological results obtained in the design, manufacturing and test of the 70,000kW class model machine, the conceptual design is being reviewed of the 200,000kW class pilot machine. In the aspect of the functional design, accurate grasping of the thermal load is essential for the purpose of attaining a large capacity for a superconducting generator, as a part of which a thermal load analytical method was planned to be established for a torque tube heat exchanger. The reasonableness of the analysis was verified through a comparison with the factory test result of the 70,000kW class slow-response type rotor, indicating good agreement between the calculation result and the actual measurement, and enabling the result to be obtained that explains dependency of the thermal load on the number of revolution.

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

    A total of 5 wells were excavated in the Hanshin-Awaji area (Ikeda, Takarazuka, Tarumi, Hirabayashi and Ikunami) to collect the core samples, which were analyzed by the AE/DR and DSCA methods to determine crustal stresses. For the AE/DR analysis, the core sample was cut in the vertical direction, and in the horizontal direction at intervals of 45{degree}. The sample of unknown orientation was provided with a datum line common for both methods, to compare the results by these methods. A load was applied to the sample, provided with an AE sensor and strain gauge on the sides, in the longitudinal direction. For the DSCA analysis, the core sample was cut into a cube having a side length of 33mm, with a pair of planes directed in parallel to the datum line. A total of 18 strain gauges, 10mm in gauge length, were attached to the cube. The AE/DR analysis gave the maximum and minimum principal stresses in the horizontal plane and stresses in the vertical direction, whereas the DSCA the maximum, intermediate and minimum principal stresses. 3 refs., 7 figs.

    Development is under way of a power generation system utilizing pressure difference during fuel gas transportation, independent from the outside and installable in the vicinity of the load. It is assumed that power is supplied to a decompression device in a fuel gas supply pipeline. Fuel gas placed under high pressure in the mainline is decompressed upon arriving at a consumer area. The intended technology of utilizing the now-unused pressure difference will be employed for power generation, and energy will be collected accordingly. Activities are conducted in the three fields of (1) the acquisition of heat sources for heating, (2) the development of technologies for compensating for seasonal and daily load variations on gas or power, and (3) the development of control technologies to cope with emergency. In field (1), a system is developed, independent from external heat sources, to operate on an indirect heating system based on a heating furnace. In domain (2), it is proved that high efficiency system operation will be available if the influence of gas pipeline transportation parameters on load variations is analyzed for the effective utilization of the pipeline operating system.

    This paper presents power load leveling and energy saving measures for heat source, air conditioning and lighting of the new Kobe branch building. The low-temperature hot-air system adopts an ice storage system, and reduces blowing power by 12 degreesC blowing in place of normal 16 degreesC blowing, and an initial cost by duct size reduction. The continuous air conditioning system levels an initial peak load of air conditioning as compared with normal air conditioning only for working hours for buildings with large heat capacity. In addition, as power load leveling measures for the whole building, the complete heat storage system using an underground internal melting type ice storage tank is adopted. Energy saving for lighting is achieved with a dimming lighting controlling its lighting output by inverter. The following effects are expected by these new technologies: Load leveling effect of 30%, energy saving effect of 20.2% and CO{sub 2} reduction effect of 24.1%. (NEDO)

    In the research cooperation promotion projects having been carried out, the R and D of an overall recovery system have been conducted which recovers effectively and systematically valuable resources such as magnesium, bromine and boron including in brine made after the salt manufacturing in the coastal region in Mexico. In this project, as the research on the distilling process needed for commercialization of the system to recover valuable resources from the brine, Japan has been collecting information on various distilling processes and solar pond systems and studying a distilling process appropriate to the site jointly with Mexico. As a result, a seawater desalination process which combined the solar pond using solar energy and the evaporation method was recommended as a low-priced distilling method. Moreover, it was indicated that the solar still method for condensing/recovering the evaporated water of the Guerrero Negro salt pan is also less influential in the salt manufacturing process and is viable as a most economical distilling process by studying the structural design and operational method of more efficient solar stills

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

    The aim of the work was to create new industrial technologies utilizing low-temperature energy satisfying local needs through developing new technologies, including air conditioning technologies high in reliability and excellent in energy efficiency. The objectives of the effort were to elucidate the behavior of moisture in the atmosphere below the freezing point and to develop farm product preserving technologies, to develop highly efficient energy conversion technologies for use in the low-temperature zone, latent heat storing cold heat technologies, and system evaluation. Constructed in connection with the last-said system evaluation were three technologies, which were a below-zero high-humidity air conditioning technology based on the outcome of agricultural verification of farm product storage, energy-efficient low-temperature storage of farm products which was a combination of a low-temperature oriented energy-efficient energy conversion technology and a clathrate hydrate-aided cold heat storing technology, and a technology applicable to business in the low-temperature processing field accessorial to the said technologies. They were compared with the conventional technologies, and then it was found that the most energy-efficient system, as endorsed by a 40-50% reduction it caused in electricity rate, was a combination of a low-temperature storage, frozen food storage, hydrate cold heat storage tank, recovery facility for farm waste incineration-produced waste heat, and a pulse tube freezer.

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

    For the advanced utilization of casting iron, temperature differential austempering and partial austempering with the gradient mechanical properties of ADI (austempered ductile iron) by local electric method were experimentally investigated. For the former, gradient mechanical properties are obtained by giving temperature difference to the material in the process of austempering of casting iron, to add the strength and toughness. For the latter, mechanical properties are controlled by repeating partial austempering with changing the isothermal transformation condition by means of local electric method, to obtain the strength characteristics with appropriate balance. As a result of the former experiment, function gradient materials could be obtained with continuously changing internal mechanical properties. The fabricated material provided different properties depending on the direction of load. Radial crushing strength constant of the ring material depended on the treatment temperature of inside surface of the specimen. Fatigue and yield strengths can be simultaneously improved. As a result of the latter experiment, it was found that the mechanical properties can be improved at arbitrary part by the partial austempering. 13 refs., 25 figs., 4 tabs.

    This paper introduces one example of research relating to the corrosion of sprayed coating at the Institute. The research has been conducted, in the environment of a frozen water solution, on the corrosion characteristic of aluminum-zinc thermally sprayed coating which is applied to the anti-corrosion of an aluminum and steel base material. The purpose is the protection against corrosion of the base material by dissolving this coating. Regardless of the sprayed coating, the characteristic of the surface-covered coating is very similar to that of electroplating. As a result of the examination of the corrosion characteristic of WC/Co based sprayed coating, corrosion resistance was found to be improved by adding Cr to the binder of Co. In the acid environment, WC/Co seems to be effective for corrosion resistance. Using the method of cladding by plasma powder spraying, a surfing layer of an Ni-Cr alloy was made on the surface of a carbon steel, with carbide particles dispersed, thereby examining corrosion resistance, wear resistance and high temperature oxidation characteristic. The cladding by welding of the Ni-Cr alloy was performed before carbide was dispersed, suppressing the dilution of Fe from the base material, which revealed great improvement in corrosion resistance and high temperature oxidation.

    To promote the succession of history of and the creative use of industrial science technologies, the paper made lists and databases of the articles of industrial technology museums and material halls in Japan. Record/preservation and collection/systematization of history of the industrial technology is useful for forming bases necessary for promotion of future research/development and international contribution. Museums and material halls are the fields for making comprehensive and practical activities. The data were made as one of the basic databases as the first step for promoting activities for examining the technical succession situation in a long term range continuously and systematically. In the classification of the data, the energy relation was divided into electric power, nuclear power, oil, coal, gas and energy in general. Others were classified into metal/mine, electricity/electronics/communication, chemistry/food, ship building/heavy machinery, printing/precision instrument, and textile/spinning. Moreover, the traffic relation was classified into railroad, automobiles/two-wheeled vehicles, airline/space, and ships. Items were also set of life relation, civil engineering/architecture, and general. The total number of the museums for the survey reached 208.

    A sharp rise in industrial productivity in Asia countries indicates a rising level of R and D technology. Since Japan has not clearly grasped the R and D ability in these countries, it has not given appropriate personnel/material R and D support to them. Therefore, for the purpose of exactly grasping the R and D ability of Asian countries (Korea, Taiwan, the Philippines, Indonesia and India) and studying an effective and appropriate method for R and D cooperation, a survey was conducted of R and D potentials in Asia and R and D support policies of the countries. As a result of the survey, the following are taken up as items to be considered: promotion of exchanges between Tsukuba, etc. in Japan and research/university towns and science parks being constructed in lots of countries, participation of private companies in high-tech joint work in cooperation with Japan, sending information from Japan using internet, etc. and exact grasp of needs at partner side, cooperation given to new comers without asking for research results (use of OB researchers, etc.) 25 refs., 39 figs., 59 tabs.
