    Rapid economy growth has been observed in Asia including Japan. On the other hand, problems of population and environment grew even worse with the economic growth. Especially, China is the second CO2 emission country in the world. Large energy demand is still forecasted with its economic growth in the future. It is well-known that the energy consumption per unit GDP is very large. Therefore, it is very significant to promote the activities implemented jointly with China for mitigating the emission of greenhouse gases including CO2, which provides a significant meaning for solving global environmental issues as well as for improving regional environmental issues. It is necessary for the above to recognize the appropriate current situations and to promote the activities implemented jointly suitable for the country. Based on the discussions and information exchanges about environmental issues with staffs concerning environmental policies and scientists as well as the field surveys, methods for the activities implemented jointly were investigated to provide some proposals. 4 figs., 8 tabs.

    The Kyoto Protocol allows some flexibility in the implementation of methods for achieving the goal, such as emission trading, activities implemented jointly (AIJ) among advanced countries, construction of clean development mechanisms (CDM) with developing countries, etc., and Japan intends to positively make use of them for the achievement of the goal. For China, who holds second place in the list of greenhouse gas emitting countries in the world, the promotion of CDM is quite important. With the situation taken into consideration, interaction was effected with Chinese officers and scientists of government agencies and academic institutes involved in environmental matters, and researches were conducted. Views and information were exchanged regarding environmental problems and, after on-site investigations, researches were conducted and suggestions were presented as to how AIJ and CDM should be. The suggestions covered Chinese policies toward AIJ and CDM, current state of AIJ projects in China and systems for their promotion, means for enhancing such projects, and discovery of candidates for AIJ and CDM project application.

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

    For prevention of global warming by greenhouse effect gas, study was made on energy saving measures for Achinsk refinery in Russia. Achinsk refinery is a relatively new plant put into operation in 1983, however, because of no various equipment for use combustion heat effectively, its average thermal efficiency is as low as 60%-70%, resulting in fuel consumption more than necessary one. Based on the study result, the following remodeling designs were made: Improvement of a heat exchange efficiency by relocation of heat exchangers to reduce fuel consumption of a heating furnace as much as possible, conversion of an existing heating furnace based on an old design concept to an advanced one, installation of a waste heat recovery system including a preheating convection unit and air preheater, reinforcement of heating furnace wall insulator, installation of an optimum control system for furnace operation, and improvement of a fuel supply system efficiency. This design showed possible reduction of heating furnace load, and possible furnace thermal efficiency of 90%. (NEDO)

    Investigations and discussions have been given on measures to improve energy conservation and efficiency at a power plant of Kish Water and Power Company (KWPC) in Iran. The site has high ambient temperature throughout a year, making the gas turbine power plant capable of generating power only at about 70% of the rated output, with the power generation efficiency decreasing. The project has analyzed the current situation at the plant, and evaluated different means that appear effective in improving the efficiency, including the gas turbine absorbed air cooling system, the steam injection system, and the combined cycle. As a result of the discussions, it was revealed that energy saving effect can be obtained at 145 TJ with the gas turbine absorbed air cooling system, 224 TJ with the steam injection system, and 1017 TJ with the combined cycle. The annual reduction of greenhouse gas emission due to the above energy conservation would be about 11 thousand tons, 16.5 thousand tons, and 75 thousand tons, respectively. However, the investment payback period would be about 2.45 years, 8.31 years, and 14.21 years, respectively. Therefore, the profitability does not appear very attractive because of low fuel unit cost. (NEDO)

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

    The monetary crisis in Thailand with the baht drop in July 1997 as a beginning rapidly worsened the Thai economy. With it, the number of automobiles sold sharply declined, and automobile manufacturers were also heavily damaged as seen in the temporary discontinued production, etc. Under such economic situation, a discussion was made on execution of the project with the Thai Automotive Industry Association (TAIA), a partner at the Thai side. As a result, agreement was made on the positioning of the project, role sharing, and selection of measures against heavy traffic as follows: Japan Automobile Manufacturers Association (JAMA) conducts a feasibility study, proposal of a construction plan and confirmation of effects, and bears the costs. TAIA bears the execution and cost of construction (Due to the worsened Thai economy, JAMA paid almost all the construction expenses). In the light of the economic situation in Thailand, `improvement of the signal control system` was selected as an execution candidate, which has the highest cost effect among the measures against heavy traffic. In the future, the application, registration and execution are done for joint activities for the project. 49 figs., 59 tabs.

    Discussions were given on application to the steel mills in China of a 1100-degree C class high-efficiency combined cycle power plant (CCPP) exclusively firing blast furnace gas developed jointly by Kawasaki Heavy Industries Ltd. of Japan and ABB Corporation of Switzerland. The CCPP can utilize the energy possessed by a fuel without waste from high temperature zones to low temperature zones, being capable of attaining high efficiency that cannot be achieved with the single cycle. The CCPP has the efficiency exceeding that of the BTGP by about 10% or more in absolute value. The investigations and discussions were given on Shougang General Corporation, Anshan Steel Corporation and Wuhan Steel Corporation. As a result, in the plan for the power plant of Shougang General Corporation on which both parties have agreed, the project implementation can be expected to result in electric power generation of 110 MW in annual average, factory air supply of about 100 tons per hour in annual average, and annual reduction of carbon dioxide of 841 kilo tons. Wuhan Steel and Anshan Steel will require implementation of further detailed investigation, but the possibility of realization is considered high (NEDO)

    A research is conducted into China's current problems of energy-related environments, and studies are made for the assessment of its potentials for greenhouse gas reduction, such as CO2 from coal, and for the prevention of environmental pollution in urban areas. By the survey of the current states of the supply and demand of energy and heat in China, and in Beijin, it is found that fuel conversion, which means the disuse of coal in this case, is necessary for a success in SO2 measures in the heat supply department. Since the rate of concentrated heat supply undertaken by heat supply businesses is low, it is inferred that potentials for CO2 reduction are quite high in this department. Concerning technological problems about conversion from coal to natural gas and heat supply, deliberation is made on a scenario covering how to approach the energy demand model, combustion in the natural gas boiler, and the home heating fuel. In discussing air pollution in China, the difficulty known as transboundary air pollution is taken up. It is concluded that conversion from coal to natural gas or coal disuse will serve effectively the purposes of energy saving, SO2 reduction, and CO2 reduction. (NEDO)

    Discussions have been given on the improvement and modification project intended of saving energies and reducing greenhouse gas emission in the Potoshani district heating and heat supplying facilities in Romania. Thirty years have elapsed since the building of the Potoshani district heating and heat supplying facilities, whereas noticeable energy loss has occurred due to aged deterioration, such as thermal efficiency decrease, performance decrease, and hot water leakage due to piping corrosion. The present project is intended to improve the heat production and power generation facility efficiencies, and reduce the heat loss in heat transportation and distribution to less than 5%. The improvements will be implemented by replacing and rehabilitating the existing boilers, replacing the turbine generators, and replacing the transportation and distribution pipelines and heat exchangers. As a result of the discussions, the present project is estimated to result in annual fuel conservation of 35,820 tons of crude oil equivalent, and annual reduction of the greenhouse gas emission of 110,835 t-CO2. The total amount of the initial investment for the project would be 11.369 billion yen, and the payback period would be 12 years. The project will produce profit of 31.358 billion yen in 20 years, thus the project is financially feasible. (NEDO)

    For the state-run plant of Pakistan Steel in Pakistan, an investigational study was conducted on energy conservation and reduction in greenhouse effect gas emission. In the project, energy conservation technology on the following was tried to be introduced: coke oven coal moisture control (CMC) equipment, sintering cooler waste heat recovery equipment, blast furnace hot stove waste heat recovery equipment, blast furnace pulverized coal injection (PCI) equipment, blast furnace top pressure recovery turbine (TRT) equipment, and hot strip mill heating furnace regenerative type burner equipment. Further, in the project on environmental improvement, studies were made on coke oven environmental improvement and blast furnace cast house dust collection. The results of the study indicated that economical effects of the energy conservation project were considered as low because the unit price of energy of Pakistan Steel is low. However, substitution of the low-priced domestic coal for the imported coal has a good effect, and energy conservation in the TRT power generation and by the regenerative type burner produces a highly economical effect. Therefore, Pakistan Steel also agrees to positively promote the project. Moreover, concerning the environmental improvement project, it was considered that the necessity of the project is high in the relation of the coke oven aimed at reducing emissions of toxic substances.

    An investigational study was conducted on the project for energy conservation and reduction in greenhouse effect gas emission at the existing district heating plant in Tbilisi City, Georgia. In the project, the following are conducted for the district heating plants in the Didi-Digomi section and Saburtalo section: renewal/higher efficiency of boiler equipment, adoption of cogeneration using gas turbine, improvement of hot water pipeline and improvement of equipment at heat users. As a result of the study, one plan for cogeneration of 2 units x 6MW class in each section was good in terms of economical efficiency and expenses vs. effects, and the other plan for cogeneration of 17 units (8 units and 9 units) x 6MW class was good in terms of the generated output and regional needs. The amount of energy conservation to be made by the former plan totaled 22,678 toe/y in both sections. The amount of greenhouse effect gas reduction is 70,170 t-CO2/y. The internal earning rate is 1.707% in the Didi-Digomi section and 2.249% in the Saburtalo section. The project profit is lower than the initial investment cost, and therefore, it is necessary to consider the profit from the CO2 emission right. (NEDO)

    Investigations and discussions have been given on energy saving possibilities at two medium-sized heat and power supplying plants in the city of Dailian in China. The project will improve the operation methods of the heat and power plants so that the energy cost can be minimized, and attempt to improve the boiler heat efficiency and save the energy by means of heat recovery and utilization. The draft modification plan for energy conservation has planned operation optimization for energy conservation, control of boiler operation under variable pressure, modification of the external boiler heat converter, use of inverters for the large capacity motors for boilers, and recovery of heat from the boiler blow-down water. In the analysis, models were structured from the operation data, and the effects of applying the energy saving measures were derived from simulation. As a result, the energy saving effect was found to be about 13,000 tons at the Chunhai plant and about 7,000 tons at the Pulandian plant annually (converted to oil). The reduction in greenhouse gas emission was found to be about 40,000 tons at the Chunhai plant and about 20,000 tons at the Pulandian plant annually. The number of years for investment payback is about 4.1 years at the Chunhai plant, and about 4.9 years at the Pulandian plant, wherein good profitability can be estimated. (NEDO)

    Having the Mining Industry Restructuring Public Corporation located in the city of Katowice, Poland as the counterpart, a feasibility study has been executed on a project to utilize coal bed gas for power generation. Selected for the study are the 'Budryk coal mine' owned by KWK 'Budryk' Coal Company and the 'Pniowek coal mine' owned by Jastrzebie Coal Company. Since the Pniowek coal mine can utilize the whole quantity of recovered methane by 2001, the Budryk coal mine was selected as the object of the project. As a result of the trial calculation on the economy when the new gas power plant is installed in the Budryk coal mine, the energy substitution effect was found to equal to a power amount at transmission terminal of 6 MWh/year. Furthermore, when proliferation effect is taken into consideration, an enormous effect can be expected if new coal mines are developed and the existing cola mines will go further deeper, because the Silesian coal mine presently has the coal resource quantity of 57 billion tons and the annual gas discharge quantity of 750 million m{sup 3}. Therefore, if the technologies to recover, manage and utilize the gas are established at the Budryk coal mine, a large effect leading to an aspiration would be expected under the current situation of the structural reorganization under which the Polish coal companies are placed.

    A potential study in FY 1998 was made of the energy/environment related activity implementation joint (COP3 related AIJ) in 6 Southeast Asian countries. Vietnam is a country which is the lowest in greenhouse effect gas (GHG) emission in the world, but they want the international assistance for their continued development and contribution to the global environment. Laos has to continue their economic development for extermination of poverty and improvement of life level. Accordingly, AIJ has to be the one that supports those and is helpful for both industrial development and environmental improvement. The same in Cambodia as in Laos, AIJ has to be the one that is helpful for both industrial development and promotion of environmental improvement. In Myanmar, GHG emits (CO2 conversion) 94.5% in the agricultural sector where methane is emitted from livestock and rice growing. There, the forest protection plays a big role. In Thailand, the use of land and forest protection are subjects mainly with the heightening of energy efficiency and fuel substitution. Malaysia, of course, promotes the economic development, has the leading GHG policy (traffic management in urban area, etc.), and wants the international technology transfer. (NEDO)

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

In order to promote the AIJ Japan program smoothly, some practical examples in every preceding country and the situations and demands of Asian countries were researched. It was confirmed that since larger cost-effectiveness is achieved just in countries lower in emission control cost, AIJ can enhance the cost-effectiveness and promote environmental technology transfer. Japanese government had studied establishment of the framework for AIJ, and decided the basic framework of the AIJ Japan program in 1995. The government also approved the evaluation guidelines of this program which include confirmed and considered matters necessary for government offices related to this program to evaluate and approve each project.

This paper explains the fiscal 1999 results. The project A is the installation work of one additional circuit (159km, 130MVA) on a 132kV transmission line between Lawpita and Kalaw. The supporting structures for this line have already been designed for two circuits. The nation considers it to be the highest priority with the purpose of reducing losses as well as providing stable power supply (it is directly connected to the Baluchaung hydro power plant generating 1/4 of the entire power supply in the nation). The project B is the new installation of a 33kV distribution line between Aung Pin Lae and Mayangyan. This is scheduled for Mandalay where a large growth is anticipated in the demand for electric power. The construction expenditures are, in thousands of Yen, 498,050 (for Japan) and 16,119 (for Myanmar) for the project A, and 309,448 (for Japan) for the project B. The measurable loss reductions are estimated as 1,280kW and 660kW respectively for each project, with both EIRRs surpassing the social discount rate of 10%, indicating economically profitable projects. Years to recovery of investment for the project A and B are 25 and 10 years respectively. (NEDO)

The base of the quaternary period stratum exists at depth of 50-400m, while the coal seams at depth of 300-700m. Among 11 existing seams, the 1st and 5th seams are main objects for prospecting. The 5th seam of 0.2-8.96m (2.95m in average) thick is the most expected important one, distributing all over the mine property. The 5th seam also has branch seams spreading over 2.5km from east to west and 1.2km from south to north in the center part of the mine property. The 1st seam of 0-8.62m (2.90m in average) thick is most thick in the south part of the mine property. The theoretical amount of coal deposits in the whole coal seam is estimated to be nearly 290,000,000t by Chinese group (nearly 50% of it in the 5th seam). That is also estimated to be nearly 346,000,000t by Japanese group (155,000,000t in the 5th seam). Both 1st and 5th seams are composed of sub-bituminous coal. (NEDO)

    In promoting international collaboration research project, coordination of the patent system of each country which participants to the project belong to has broad implications in concluding the contract for the project. For example, in Japan, 100% of the patent belongs to the government for contrast or collaboration project with the government. While, in the USA, the patent developed by the private company belongs to the private company even for the contrast project. In Japan, the shared patent can not be transferred to the third party or implemented without agreement with the partner. While, in the USA, the shared patent can be transferred to the third party or implemented without agreement with the partner. Due to such a difference, some projects can not be established by ill coordination of intellectual property even when the meaning of the projects is well understood.

    What impedes the popularization of the guided boring system is the functional insufficiency of the drilling position measuring method. For the purpose of properly dealing with the situation, efforts are made to develop a new drilling position measuring method which is highly reliable even when there exist previously buried pipes or electromagnetic noise. Activities are conducted in the two sections of (1) the study of an drilling position measuring method not to be easily affected by magnetic noise and (2) the study of a method for detecting previously buried objects. In section (1), based on the technology of a drilling position measuring system (locator) which is currently the most popular among horizontal drilling systems, a signal processing technology capable of reducing the effect of noise and a new position measuring method are contrived, and it is proved by the use of an experimenting system that they work effectively. In section (2), with attention paid to the small horizontal drilling device, an underground radar technology with the radar probing into the ground from the ground surface or from a drilling head is studied as an effective and easy-to-use method for detecting previously buried steel pipes.

    This paper makes an analysis on the characteristics of R and D concerning Australia, one of the core nations in the cooperation, on the basis of the idea that 'establishment of new comparative superiority through cooperation' can be realized by joint work among Japan, Australia and Asian nations. In Australia, it was found that R and D was often promoted through a new idea obtained by recruiting heterogeneous persons and communicating mutually internally. It was also found that in Australia an affinity exists to such persons of different nature. Accordingly, Australia was presumably quite suitable for the place to bring up the persons of developing nations. On the basis of these analytical results, proposal was made to promote three programs; namely, preparation of a data base for R and D organizations and the staff, commencement of a partnership program, and opening of a needs searching conference.

The recovered gas is to be supplied to the cities of Tiefa and Tieling as town gas, for which compressed gas feeding and controlling technologies and facilities will be introduced. This paper lists the gush-out quantity (1,000 Nm{sup 3}), the recovery quantity (1,000 Nm{sup 3}), the recovered gas concentration (%), the utilization quantity (1,000 Nm{sup 3}), and the utilization rate (%). The figures for the respective items before and after the implementation are 128366, 32949, 44.5, 7000, 5, 123500, 43890, 49.1, 39826, and 32. The quantity of gas gushing out at facings decreases in association with increase in the recovered gas quantity, whereas the gas concentration at facings in the Daixing mine in 2003 is estimated to decrease to 0.1%, contributing to safe mining operation. The test drilling for medium measure horizontal degassing expands the degassing assured scope per one test drilling seat, and can reduce the total test drilling length and construction amount.

    For the prevention of environmental contamination due to oil-based ink used in the photogravure printing process, efforts were exerted to develop a technique of laser-aided photogravure printing using a water-based ink. It was learned that the laser optical system technology of CR Corporation of Canada was practical and high in quality, and a delay occurred in the development of an evaporation type resin for use under this project. Then the initially planned design was abandoned for a type using a new optical system manufactured by CR Corporation. In the development of plate making materials, it was found that resin evaporation was incomplete in a 1-layer structure design. A 2-layer structure design was then employed instead, and the evaporation goal was achieved. Now that the optical system was changed, the resin was also replaced with a thermosensitive type, which enhanced work efficiency. The CR Corporation-manufactured laser optical system was installed on a mount, the processor system was controlled and adjusted, and a printing test was conducted using a water-based ink of German make. It was found that the product of the new system was higher in quality than that printed by the conventional mechanical perforation type printer using an oil-based ink. (NEDO)

    Described herein are the results of the developmental research on the high-performance plasma-assisted fine coal powder combustion mechanism for coal-fired power generation boilers, a theme adopted by the international cooperative research scheme. The program for design/manufacture of the plasma torch manufactures laminar type torches for 100kW high power class and 10kW middle class. The high-performance plasma-assisted combustion mechanism is designed and manufactured using the torch. It has a structure which supplies secondary air and secondary coal flow to the primary coal flow. It is tested for starting up a commercial boiler firing finely pulverized coal, to confirm its functions. The tests for optimizing the oilless ignition and operation are conducted in Tashtagonal Iron Plant and Berdsk Chemical Plant. It is found that the cold start can be realized in the boiler, when the muffle burners are preheated for 30 to 40 minutes before the finely pulverized coal is supplied and the steady-state coal combustion is attained 3 to 5 minutes after the coal is supplied. The program for the combustion basics for the plasma-assisted mechanism collects the data related to its dependence on coal type. (NEDO)

    Development has been advanced on technologies to manufacture methanol efficiently by combining a technology to convert selectively fibrous material based biomass into sugar under high concentration sulfuric acid condition with the immobilized enzyme flash fermentation process, both being developed in the United States. Activities have been taken in the following three fields: 1) establishment of an optimal biomass treatment condition by using concentrated sulfuric acid, 2) chromatographic separation of sugar and sulfuric acid, and 3) discussions on conditions to apply the immobilized enzyme flash fermentation process. In Item 1), discussions were given, using rice straw and waste woods as the object, on effects of biomass particle size, sulfuric acid to biomass feeding ratio, sulfuric acid concentration, reaction temperature and time on the cellulose to hemicellulose reaction ratio and the sugar conversion factor, whereas it was revealed that the governing factors are the biomass/sulfuric acid contact area and the reaction temperature. In Item 2), a chromatographic device filled with anion ion exchange resin was used to set the sugar recovery rate of 100% and the sulfuric acid recovery rate of 93%. (NEDO)

    The response strength in which deflection waves propagating in the elastic body of a large floating structure with an order of km in length and width was investigated. Attention was paid to the waves propagating the place fully away from the boundary of a very large floating body so as to obtain the dispersion relation of waves and the relation between incident waves and deflection waves. Next, the frequency response was checked from the aspect of the displacement amplitude and strength for beams and plates. The dispersion relation of waves propagating the place fully away from the boundary of a very large floating body and the relation between the waves and infinite-point incident waves were represented by an expression. Similarly, the waves propagates more than the infinite-point incident waves in frequency, wavelength, and speed. A lower-limit value exists in the propagation speed. The displacement and stress amplitudes are represented by a relational expression. For plates, the displacement amplitude increases when the wave direction coincides with the small-rigidity direction. The stress amplitude is maximized when the waves corresponding to the ``wave below a floating body = size of a characteristic wave number`` reach the large-rigidity direction. 10 refs., 10 figs., 2 tabs.

    Recently, span of cable-stayed bridges has been getting loner and longer, present situation is that cable-stayed bridges with span 600 to 800m class have been built inside and outside the country, and accurate determination of its ultimate strength has been an important problem statistically. However, concrete design method for evaluating load bearing stress of long-span cable-stayed bridge. Particularly of the main beam whose axial stress is dominating, has not been established so far. As for cable-stayed bridge, even for long-span, effect of plasticization of cross section on ultimate strength is severe because there is little effect of geometric nonlinearity and it is thought that accurate evaluation of ultimate strength only by elastic finite potential analysis is difficult. Accordingly, it is necessary to study the behavior by using combined nonlinear analysis considering the nonlinearity of the material in order to evaluate the safety and economy to long-span cable-stayed bridge. In this report, 3 dimensional analysis method was formularized taking into account the combine nonlinearity of multi-box girder and analysis program of ultimate strength behavior of long-span cable-stayed bridge was developed. 19 refs., 17 figs., 2 tabs.

    Carboxyl in coal was focused in discussing its pyrolytic behavior while tracking change of its absolute amount relative to the heating temperatures. A total of four kinds of coals, consisting of two kinds brown coals, sub-bituminous coal and bituminous coal were used. Change in the absolute amount of carboxyl due to heating varies with coalification degree. Decomposition starts in the bituminous coal from around 300{degree}C, and is rapidly accelerated when 400{degree}C is exceeded. Carboxyls in brown coals exist two to three times as much as those in bituminous and sub-bituminous coals, of which 40% is decomposed at a temperature as low as about 300{degree}C. Their pyrolytic behavior at temperatures higher than 400{degree}C resembles that of the bituminous coal. Carboxyls consist of those easy to decompose and difficult to decompose. Aromatic and aliphatic carboxylic acids with simple structure are stable at temperatures lower than 300{degree}C, and decompose abruptly from about 400{degree}C, hence their behavior resembles that of carboxyls in bituminous and sub-bituminous coals. Structure of low-temperature decomposing carboxyls in brown coals is not known, but it is assumed that humic acid originated from natural materials remains in the structure. 4 refs., 3 figs., 1 tab.

    Rotating bending fatigue tests of smooth specimens were carried out at room temperature on a pearlitic ductile cast iron (PDI) and austempered ductile cast iron (ADI). No significant difference due to sampling position from cast blocks in both materials was found in fatigue limit and fatigue life distribution. Then, the statistical fatigue properties of ferritic (FDI), ferritic/pearlitic (FPDI), pearlitic and austempered ductile cast irons were investigated. The fatigue life distributions of all ductile irons were well represented by the three parameter Weibull distribution modified by the saturated probability of failure. The shape parameters of FDI, FPDI and PDI were in proportion to {sigma}/{sigma}w independent on micro structure, while the shape parameters of both stress levels in ADI were smaller than unity. The fatigue strength of ADI was highest, but the scatter of fatigue life was largest among the all cast irons. 13 refs., 15 figs., 7 tabs.

    The hydrodynamic behavior of liquid in a fermenter has a great influence on the quality of beer. Therefore, temperature distribution, gas germination rate, bubble size, bubble rise velocity, gas holdup, and liquid flow rate in fermenters in brewing of beer are measured to investigate the hydrodynamic behavior experimentally. CO2 germination rate, local gas volume flux, and liquid flow rate are measured using a conical fermenter with 1m diameter and 3.5m height. A two-dimensional conical fermenter with 0.3m width and 1.3m height is used for the measurement of bubble behavior, bubble size distribution, bubble rise velocity, and gas holdup distribution. It is found that a circulating flow is produced in the fermenter due to density difference caused by gas holdup distribution, and hydrodynamic behavior of liquid in a conical fermenter for beer brewing can be explained quantitatively by circulation flow theory of the bubble tower. 7 refs., 11 figs.

    The reaction process of coal liquefaction which uses ultrafine pulverized coal having a particle diameter of several micrometers was investigated in order to improve the catalytic efficiency between coal and catalyst. Two kinds of samples were prepared by crushing Taiheiyo-coal into less than 100-mesh by usual technique and further pulverizing the crushed coal to several [mu]m. When iron oxide catalyst, sulfur and tetralin solvent were used, pulverizing does not bring a significant improvement in conversion rate and the yield of liquefaction oil capable of being distillated. This is considered to be due to the coagulation between fine particles before or during reaction, suggesting the importance of selecting reaction conditions etc. In the case of pulverized coal, hydrogen consumption is high and hydrogenation of heavy fractions such as SRC proceeds. When liquefaction-oil circulating solvent and red mud-sulfur-based catalyst were used, gas yield was low in pulverized coal, but no significant improvement was not shown in oil yield of liquefaction oil. The conversion rate and SRC yield were somewhat high in the case of pulverized coal. 3 figs., 2 tabs.

    With an objective to evaluate effects of clayish minerals in the electric and electromagnetic exploration methods, resistivities were measured on samples which have adjusted contents of clayish minerals. Samples were prepared for an experiment by mixing 300 g of glass beads having a diameter of about 1 mm, 200 g of aqueous solutions, and 3 to 90 g of smectites. The aqueous solutions used KCL, NaCL and CaCL2 at concentrations of 0.1 to 0.001 mol/L. The result of the experiment may be summarized as follows: among the three kinds of smectites, KN-1 has the greatest effect to reduce the resistivity; the resistivity decreases when the smectite amount is increased except when the concentration of the solution is high; this phenomenon is thought to be caused by increase in the region of an electrically doubled layer which has higher ion concentration; change in the resistivity increases when the solution concentration is low, and decreases when the concentration is high; and in the case of the solution concentration being 0.1 mol/L, the resistivity increases with increase in the smectite content. 5 refs., 7 figs., 1 tab.

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

    A case study on A city was conducted aiming at making a detailed manual for introducing the waste-fueled power generation. The study was made in terms of a large-capacity waste-fueled power plant, estimation of the waste amount considering wide-area processing, size of facilities, comparison of four types of combustion furnace, steam condition/seawater cooling/power generating efficiency, etc. As a result, the following were proposed: As to the size of facilities, a capacity as large as possible is recommended in the light of the scale merit of costs of the waste-fueled power plant and final disposal site and the environmental preservation. Concerning the high efficient power generation, recommended are 450degC and 60-80 ata which are steam conditions for coping with high temperature corrosion. In respect to seawater cooling, the adoption is recommended making good use of locational conditions since the output energy increases by approximately 16%. Any furnace types including the fluidized bed furnace are equal. The amount of dioxin becomes below 0.1ng/Nm{sup 3} because of the control of furnace combustion temperature, residence time, catalytic desulfurization facilities, blowing of activated coal into the flue, etc. 172 figs., 78 tabs.

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

    Discussions were given on fatigue strength of corroded steel plates taken from a hull of a ship seventeen years old after construction. The steel plates have had their original thickness of 13 mm reduced to 5.3 to 8.3 mm. After having been cut by a machine, the steel plates were used for tests as ground plates after going through grinding and as corroded plates with rust remaining on them. The fatigue test was performed in artificially made sea water at a temperature of 25{degree}C and in air with axial power pulsating tensile load and at iterative loading velocities of 3 to 5 Hz. The corroded material test verified that corrosion pits exist innumerably on the test piece surface and fatigue cracks have been developed and grown from bottoms of the pits. The stress concentration coefficient of the corrosion pits was about 1.9. Good agreement with the test result was found in the S-N chart in which the number of iteration of fracture was regarded as the number of iteratively generated cracks, and notch coefficient was estimated as 1.9. These results proved that the fatigue strength assessing method for virgin materials can be applied also to steel plates which have been exposed to corrosive environment for extended periods of time. 5 refs., 7 figs., 1 tab.

    Mineral matter in coals is important in various senses for coal liquefaction. It is possible that the catalytic activity is affected by the interaction between catalyst and mineral matter. Iron-based catalyst forms pyrrhotite in the process of liquefaction, but the interaction between it and mineral matter is not known in detail. In this study, the interaction between mineral matter and catalyst and the selective reaction between them were investigated. Tanito Harum coal was used for this study. This coal contains a slight amount of siderite and jarosite besides pyrite as iron compounds. Liquefaction samples were obtained from the 1 t/d NEDOL process PSU. The solid deposits in the reactor mainly contained pyrrhotite and quartz. A slight amount of kaolinite was observed, and pyrite was little remained. It was found that the catalyst (pyrrhotite) often coexisted with quartz, clay and calcite. 8 figs., 2 tabs.

    The holding time of austempered spheroidal graphite cast iron material is allowed to vary in heat treatment especially at the lower bainite transformation zone during the process for the preparation of specimens different from each other in the amount of {gamma}-pool, and the specimens are tested for their rolling contact fatigue strength. The effects of the amount of {gamma}-pool, roughness of the bainite structure, and work-hardening, on the rolling fatigue strength are also studied. Findings obtained as the result of experiment are stated below. In the case of an austempered ductile cast iron specimen containing a {gamma}-pool amount that occupies a high rate of 6.52%, the rolling fatigue withstanding limit exhibits a relatively high level of 1310MPa, which becomes approximately 1245MPa when the holding time is extended in the lower bainite transformation zone. The limit rises to approximately 1320MPa at a stage where the {gamma}-pool virtually disappears. In a successive austempering treatment process that aims at improving on machinability and at allowing sufficient fatigue strength to be maintained, it is necessary to allow the holding time in the bainite zone to be long enough for the {gamma}-pool to disappear and for the lower bainite structure to grow sufficiently. 5 refs., 10 figs., 4 tabs.

By considering such tendency, Materials Research Committee of Japan Steel Association carried out a co-operative research on the transformation behavior of steels. Objected steels are mainly high tensile strength steels and tempered steels, and steels for machinery structures. The research was performed on the items, such as the transformation from processed austenite and its properties, transformation and properties of steels with accelerated heating and cooling, and transformation and properties of reheated medium carbon steels. The author discusses the comparison with the transformation from unprocessed austenite, the effects of microalloying elements of Nb, Ti, V,B, etc., the effects of pre-existing textures on the transformation from in-equilibrium state austenite, and the transformation behavior of vainite and martensite in low temperatures. The research was carried out under considering the actual processes of practical use steels. 15 refs., 24 figs., 1 tab.

    Recently, the development of high strength low alloy steel (HSLA steel) of untempered type is advanced by using the comparatively high strength and excellent tenacity of the bainite or martensite of carbon remained being transformed. In the present researches, the superplasticity during the bainite transformation due to the continuous cooling and changes of the structure as well as the mechanical properties due to the superplastic deformation are examined with the samples of Mn-Cr-Mo system HSLA steel. The results obtained therefrom are shown as follows. The temperatre range of B[sub S] and bainite transformation is moving to the higher temperature side along with the increasing of the applied stress when it is over 60 MPa. The bainitic structure is composed of the mixture lath-like bainitic ferrite and granular bainitic ferrite in the use of having no applied stress, while the percentage of the latter increases simultaneously with the increasing of the applied stress. Transformation superplastic strain is increasing together with the increasing of the applied stress, and its increasing is over the linear function when the applied stress is above about 50 MPa. 22 refs., 9 figs., 2 tabs.

    SCWO characteristics are investigated for a vertical type, down stream continuous reactor system with mixing nozzle and sapphire windows. 2-propanol, hexane and biphenyl solution are used as fuel and air as oxidizer. 2-propanol is observed to be effective as makeup fuel to keep a stable autogenic SCWO reaction. Even for low air ratio as 1.1, high decomposition rate without CO, NO, NO{sub 2} or soot production is achieved. Calculated and experimental flue gas composition is in good agreement for a wide range of air ratio. Spontaneous flame formation is observed for SCWO of 2-propanol using air ratio over 1.8. These flame formations are not particular to 2-propanol and are also confirmed when using hexane and biphenyl solution as fuel. (author)

    In this study, incremental equation of cable-stayed bridge is formulated by finite element method taking the geometrical nonlinear analysis into account. Then, as an example of designing a bridge with 1500m span, setting up the initial tension, analysis of in-plane behavior caused by live loads as well as analysis of the behavior against wind caused by out-of-plane wind load that are necessary for designing a bridge with 1500m span are carried out. The main results obtained through the study are as follows. As for the cable stayed bridge with 1500m center super long-span having supplementary supporting points between the side arms, the geometrical non-linearity caused by the in-plane design live loads is not remarkable. The effects of wind which acts on girders on analysis of the behaviors against wind are different depending on the aerodynamic performance of the girder and in the case of high wind speed, strong effects on the behavior against wind of the in-plane and screws generate. As the changing of tension of the cable makes influences on the force of in-plane cross section and on displacement of the girder, if the wind speed is very high, the analysis results of the behaviors against wind of in-plane and screws of the cable-stayed bridge may be different depending on in what manner the wind load on the cable to be treated. 16 refs., 16 figs., 1 tab.

    Plasticity and packing structure of clay and alumina dough, and of alumina mixed with water-soluble and non-water-soluble plasticizers were investigated. It was found that both plastic clay dough and alumina dough with plasticizers showed a two-peak pore population. When the larger-sized pores increased in volume, the fluidity of the dough was improved. On the otherhand, when the smaller-sized pores decreased in volume, a high rigidity was showed. An aggregate structure was observed in the clay and the dough mixed with water-soluble plasticizer like methyl cellulose. Plasticity was generated when the aggregates were deformed by using the larger-sized pores among each aggregate. The non-water-soluble curdlan did not dissolve in the dough and remained in gel. The larger-sized pores were formed by the gel, whose deformation produced plasticity. It was understood that plasticity is fenerated when either the aggregates or the gel act as a buffer in the dough and enhance deformation of the dough. (author)

    In relation to softening, melting and solidification of coal during heating, the effect of heating rate and nitrogen gas pressure on viscosity change, and change with time in the yield of pyridine extract were measured to study the mechanism of viscosity change. In experiment, six kinds of coals were used, and their needle penetration and dilatation were measured using compacted disk coal pellets. The coking and slight coking coal heat-treated under the same condition as the above experiment were used for pyridine extraction. As the experimental result, the apparent viscosity during coal heating was dependent on heating rate, nitrogen pressure and coal kinds. The minimum apparent viscosity decreased with an increase in heating rate and nitrogen pressure, and approached to a constant value. Like apparent viscosity change, the yield of pyridine extract was also dependent on heating rate, and its temperature range nearly agreed with that of apparent viscosity change. It was suggested that the viscosity is dependent on not only the mass fraction of plastic intermediate but also temperature and the relation between plastic intermediate and other components. 3 refs., 5 figs., 1 tab.

    Rotating bending fatigue tests have been conducted at room temperature in air using the specimens of medium carbon steel (S45C), low alloy steel (SCM435) and titanium alloy (Ti-6Al-4V) with HVOF sprayed coating of a cermet (WC-12%Co) and S45C with WFS sprayed coating of a 13Cr steel (SUS420 J2). The fatigue strength and fracture mechanisms were studied. The fatigue strength evaluated by nominal stress was strongly influenced by substrate materials and the thickness of sprayed coatings. Detailed observation of crack initiation on the coating surface and fracture surface revealed that microcracks initiated at the WC grain boundary coalesced, and then the crack grew rapidly in the coating. Cracks in the substrate were initiated by the stress concentration of the crack in the coating, which was modeled by finite element analysis. For the specimens tested in this study, the fatigue strength of sprayed specimens was dominated by that of sprayed coating. Thus, the fatigue strength could be evaluated uniquely by the true stress on the coating surface. 9 refs., 12 figs., 2 tabs.

    This paper describes the deformation and dynamic stability of circular arch subjected to follower forces in a submerged membrane type marine structure reinforced by arch frames. Governing equations for finite deformations of the circular arch subjected to follower forces are introduced using an embedded curve coordinate, which are formulated by applying Galerkin method. In addition, equations of motion due to small disturbances under given condition of loading are introduced. Based on these equations, dynamic stability of the arch is analyzed by means of Runnge-Kutta-Gill method, to clarify the relationship between disturbances and instability regions and the resulting phenomena. Near the boundary regions of stability, both amplitude and cycle of deformation are greatly affected by the amplitude of disturbances. The dynamic instability is governed by the inverse symmetry primary mode with minimum characteristic frequency which is specific for the circular arch. The dynamic stability has high parameter dependency, and the instability regions have a complicated shapes. Although flattened arch has a smaller static critical load, it provides the dynamic stability against the disturbance. 5 refs., 10 figs.

    Elasto-plasticity analysis by using the finite element method was performed on a case that bi-axial compression and shear act on a thick rectangular plate, and applicability of the plasticity correction method was discussed. In the discussion, an investigation was made on effect of the loading method of a load on correlation between initial yield strength and ultimate strength of a rectangular plate under bi-axial compression. The analytical result from the finite element method was compared with estimated values derived by using the plasticity correction method with regard to the buckling strength. The result obtained may be summarized as follows: the effect of the loading method for combined load on the correlation between the initial yield strength and the ultimate strength is small; an approximation expression was derived for the upper limit of maximum initial bend of a deck panel of an actual vessel; the plasticity correction method for buckling strength as specified by classification societies has a certain applicability as a method to estimate ultimate strength on the safety side against plate thickness in a range of the upper limit of initial bend of an actual vessel; however, this method may estimate strength higher than the actual value depending on load ratio, hence attention is required. 5 refs., 8 figs.

    In a solution of macromolecules such as proteins that have surface activity, the macromolecules stabilize the foam by adsorbing at the bubble surface. These surface-active macromolecules at the gas/liquid interface lower surface energy. The macromolecules adhere to the gas/liquid interface, and then change their shapes. Hydrophobic groups in the molecule turn to the gas phase and hydrophilic groups turn to the liquid phase. The macromolecules separated from beer were dissolved in an acetic acid buffer solution, and then the surface behavior was speculated by the surface tension change. Their surface tension did not reach a constant value for several seconds, not like the low molecular solutions such as ethanol. The decrease in this surface tension could be kinetically analyzed. The surface tension decreased by the adsorption of macromolecules on the liquid surface, and by the shape changes in the molecule (the extension of molecule at the surface). In the {beta}-casein solution, the surface tension decreased in 2 steps that were more clear than in the beer macromolecule solution. This surface tension decrease is also supposed to show the adsorption of protein molecules and the shape change at the liquid surface. (author)

    It is thought that iron-based catalysts for coal liquefaction exercise their catalytic activity by forming pyrrhotite (Fe(1-x)S). However, there are still a lot of unknown problems remained concerning the formation and agglomeration behaviors of pyrrhotite. These make a difficulty for improving the activity of iron-based catalysts. In this study, sulfiding behaviors of {alpha}-iron oxyhydroxide ({alpha}-FeOOH) and {gamma}-iron oxyhydroxide ({gamma}-FeOOH) were investigated to reveal the formation and agglomeration behaviors of pyrrhotite. It was found that pyrrhotite was easily converted from ferric oxyhydroxide catalysts having large specific surface areas at the sulfiding temperature below 250{degree}C, and fine crystallites of pyrrhotite were formed at the initial stage of sulfiding. Crystal growth of pyrrhotite at the sulfiding temperature over 350{degree}C depended on the catalyst forms. It was also found that smaller crystallites of pyrrhotite were formed from {gamma}-FeOOH than from {alpha}-FeOOH and amorphous iron oxyhydroxide. 5 refs., 7 figs., 1 tab.

    Solubilization of lignite including a large amount of oxygen containing functional groups was attempted using HF/BF3, and the behavior of oxygen containing functional group, one of the important factors for coal liquefaction, was studied. In experiment, the cooled slurry of Yallourn coal specimen and solvent (toluene, isopentane) was filled into a vacuum autoclave together with HF/BF3. Reaction was performed under spontaneous pressure at 50, 100 or 150{degree}C for 3 hours. The distribution of oxygen containing functional groups in each coal specimen was determined by quantification of carboxyl group, hydroxyl group and carbonyl group. As the experimental result, the superacid mixture of HF and BF3 considerably improved the solubility of coal specimens into solvent as compared with individual HF and BF3. The solubility was 68wt% into benzene, 96% into THF and 99% (nearly 100%) into pyridine. It was suggested that production of Broensted acid with strong acidity causes strong catalysis. 6 refs., 2 figs., 1 tab.

    Electrochemical behavior of semiconducting diamond thin-film electrodes has been studied by measuring cyclic voltammograms for the anodic oxidation of 1,4-difluorobenzene in the electrolyte, neat Et{sub 4}NF{center_dot}4HF. A comparative study using a Pt-electrode establishes that the electrochemical fluorination of 1,4-difluorobenzene using the diamond electrode yields 3, 3, 6, 6-tetrafluoro-1, 4-cyclohexadiene. Furthermore no peaks corresponding to the redox reaction of Pt-electrode, i.e., the formation and reduction of PtO{sub 2}, are observed in the CVs obtained using the diamond electrode, suggesting that the diamond electrode is more stable than the Pt-electrode. The results suggests that electrochemical fluorination and the electrolytic production of elemental fluorine are possible at the dimensionally stable diamond electrode. (author)

    Behavior measurements of an apex seal of three-piece slanted horizontal split type were made, using an overhanging eccentric shaft-type single-rotor engine equipped with a multichannel packaged slip ring. To analyze the behavior, a computer plotting program was developed, by means of which the sequences of the configuration of top and bottom parts in the slot at given eccentric shaft angles were plotted on the trochoidal curves from the measured displacement data. The measurement results revealed the details of the behavior. Under high working chamber pressure, the top part of the leading apex seal is flush with the leading side of the slot, while that of the trailing apex seal is considerably tilted with respect to the trailing edge of the slot. 8 refs., 15 figs., 1 tab.

    The corrosion fatigue life was obtained using uncoated and tar epoxy resin specimens to clarify the temperature effect. The life curve for corrosion fatigue of machined and uncoated steel in the air and sea was obtained. The fatigue strength of uncoated steel largely decreases in the sea and breaks even in the nominal stress range of less than 1/2 of the fatigue limit in the air. The effect of temperature on the coated steel is represented by a corrosion coefficient. The steel coated at 25{degree}C is 1/1.03 to 1/1.13 at 40 to 60{degree}C. This showed that the fatigue strength decreases when the temperature exceeds 25{degree}C. However, it has not such tendency and significance that are represented quantitatively. There is a slight difference in the short-life area between the crack generation life and breaking life. However, the long-life area has no significance that influences the whole evaluation. In the long-life corrosion fatigue, the crack occurs from the corrosion pit due to the exposure below the coated film and progresses in the base material before the coated film is destroyed. The effect of the corrosion pit remarkably appears at a low-stress level. 14 refs., 14 figs., 4 tabs.

    Two-dimensional tumbling behavior is investigated numerically by calculating inlet flows of a tumbling-type nematic liquid crystal between parallel plates. Calculations are performed for various Ericksen numbers. At the comparatively small Ericksen number of Er=10, the director in the upper half space of the channel rotates counter-clockwise before reaching the fully developed value. At Er=50, the director shows an abrupt rotation just after the inlet section. The rotation is not only convected to the downstream area but propagated from the region near the channel wall where shear rate is large to the center region. When Er is increased further to 100, the director profile does not indicate a monotonic development but a two-step one. In this case, the velocity profile in the main flow direction is wavelike. It is found that the effect of director orientation is strongly reflected on the velocity field, while the reverse effect is weak. 26 refs., 8 figs., 1 tab.

    Cultivation of Spirulina platensis while controlling pH and nitrate ion in the culture medium was investigated in order to obtain a high density culture. In the cultivation of Spirulina platensis using sodium bicarbonate as a carbon source, the pH value increased during growth of Spirulina, and then the growth stopped at a pH value of more than 12. The cell concentration reached 2.2g/l by maintaining a pH range of 8.5 to 10.0 using CO2 gas without controlling the nitrate ion concentration. By controlling the pH and adding nitrate to a concentration of 2.0g/l, the cell concentration reached 4.2g/l at 350 hours. It was found that the cell concentration was about four times that of the culture without controlling pH and nitrate. 4 refs., 6 figs.

    Martensitic transformation and {gamma} {yields} {alpha} transformation behavior were investigated in low carbon 13% chromium stainless steels containing 2% nickel or 3% copper. The main conclusions are as follows: (1) Hardness of 2% nickel added low carbon 13% chromium steel was independent of cooling rate after hot working at large reduction. Structure of the steel was martensitic even after being subjected to such large reduction of 75%. This result suggests that ferritic transformation was hard to occur under an usual cooling rate because austenite phase was sufficiently stablized by the addition of chromium and nickel. (2) Austenite to ferrite transformation occurred only for the low carbon 13% chromium 3% copper steel without nickel even at the small cooling rate, such as 0.01K/s. This result was mainly attributed to the unstabilization of austenite phase which caused by the precipitation of {epsilon}-Cu. Furthermore, austenite of the steel becomes easy to transform to ferrite due to heavy hot working. This phenomenon was seemed to be caused by the increase in the area of austenite grain boundary owing to recrystallization. Thus, it was considered that the nucleation of {epsilon}-Cu at the grain boundaries promoted ferrite formation. (author)

    In order to study basic heat treatment properties of spheroidal graphite cast iron, the continuous cooling transformation(CCT) diagrams for the material equivallent to FCD700 under various austenitized conditions were obtained. There were 4 kinds of austenitized conditions varying from 1123K and 420s to 1323K and 1,800s. Eight kinds of cooling time from the austenitized temperature to 773K ranged from 6s to 4,000s. The transformation temperature was measured by a thermal expansion method. When the austenitized temperature was increased from 1123K to 1323K, ferrite and pearlite transformation regions moved a little in the CCT diagrams and the martensite transformation temperature decreased from 493K to 458K. The bainite region in the CCT diagrams disappeared at the austenite temperatures above 1223K. The nucleation sites of ferrite and pearlite in the spheroidal graphite cast iron were generated at grain boundary between austenite and graphite but not at grain boundary between austenites. The reason of such phenomena was also studied. 10 refs., 8 figs., 2 tabs.

    In order to get fine grain of large martensitic stainless steels products, it is available to use the isothermal transformation before the austenitizing. When 12%Cr-0.3%C steel is subjected to the full solution treatment and following isothermal transformation at 900-1,020K, it is observed that the microstructures are affected by the isothermal ageing temperature. The microstructure transformed isothermally at 1,020K is the full eutectoid structure where carbides precipitate homogeneously. On the other hand, the microstructure transformed at 900K is the mixed heterogeneous structure: the eutectoid structure where carbides precipitate densely around the edge of prior austenite grains and the ferrite structure where carbides hardly precipitate in the center of prior austenite grains. These phenomena are concerned with the decreasing in carbon content in the untransformed austenite as the eutectoid transformation progresses. The amount of decreasing in carbon at 900K is larger than at 1,020K, which causes the shortage of carbon in austenite in the last period of isothermal transformation. In the case of the isothermal transformation at 900K, the reason of why there are the ferrite structures with no carbide in the center of prior austenite grains is that the massive transformation is induced by the shortage of carbon in untransformed austenite.

    Techniques of controlled rolling and cooling are actively being used as the manufacturing process of high strength and high tenacity steel plates. The reason behind this is that the ferrite-pearlite texture can be made very finely. However, with regard to low alloy carbon steel bars with enhanced hardenability, its texture becomes hard bainite texture in the cooling process after rolling, hence its workability is not good. In this research, in lieu of controlled rolling, the possibility of the process that the tensile stress, whose effect of facilitating transformation is known, is applied before the transformation and its texture is controlled to the ferrite-pearlite texture at the cooling rate of air cooling. In other words, with regard to medium carbon low alloy steels, its transformation behavior was studied by a tensile test in which additional stress was controlled during its continuous cooling. The results are as follows: It was found that by adding stress, the ferrite transformation was expedited. This was because the nuclei formation of ferrite, which was enhanced by inner stress, was facilitated. Furthermore, when the above transformation took place at the same time of deformation, an uniform elongation about 60% was obtained. 13 refs., 13 figs., 1 tab.

    We have applied a fuel behavior model to a fuel injection system which we call SOFIS (Sophisticated and Optimized Fuel Injection System) so that we get air/fuel ratio control accuracy and good driveability. However the fuel behavior under starting conditions is still not clear. To meet low emission rules and to get better driveability under starting conditions, better air/fuel ratio control is necessary. Now we have understood the ignition timing, injection timing, and injection pulse width required in such conditions. In former days, we analyzed the state of the air/fuel mixture under cold conditions and made a new fuel behavior model which considered fuel loss such as hydrocarbons and dissolution into oil and so on. Al this time, we have applied this idea to starting. We confirm this new model offers improved air/fuel ratio control. 6 refs., 9 figs., 3 tabs.

    It has been clarified by the present authors, based on the plasma nitriding of Fe-Cr alloys and Fe-Ti alloys carried out at the temperature under 550{degree}C hitherto, that an internal nitriding layer is formed due to the fine dispersion of the particles of Cr nitride and Ti nitride in {gamma}{prime} Fe4N layer on the specimen surface. In this study, the plasma nitriding of Fe-Cr alloys are carried out at 650{degree}C, and the effects of the solute (Cr) content on the structures, nitride and the thickness distribution are examined. The main results obtained therefrom are indicated hereafter. In accordance with the observation on the cross-sectional structure of the alloys, only the nitriding layer deduced as the dispersion and precipitation of the particles of Cr nitride from {alpha}-Fe of the mother phase is formed, while {gamma}{prime}-Fe4N layer, which is found at the temperature under 550{degree}C, is not formed. The nitride of Cr generated in the nitriding layer is CrN in all Fe-Cr alloys. The hardness in the nitriding layer is constant and increases with the increase of Cr content. 13 refs., 6 figs.

    A survey was conducted on the energy situation in Thailand, Indonesia, Malaysia, the Philippines and India, and a possibility of making an international joint research. Thailand has sharply increased investments from Europe and the U.S. since 1985, and has been making a rapid industrialization. As to the energy policy, it is important to secure the stable supply and stabilize the price. Indonesia has been rapidly increasing energy consumption in accordance with the recent economic growth, and is fear of becoming a net oil importing country in the near future. They are taking a policy for securing as much domestic oil and gas as possible. Malaysia has been keeping a high growth of over 8% per year for the past 8 years and rapidly increased energy demand. It is expected that they will maintain a high level of the development of energy resources. In the Philippines, the industrial energy is mostly coal, but electricity expected in future is from the oil-fueled power generation. The stable import of oil is a problem. 45 figs., 51 tabs.

    It is said that, as long as a head rest is used in an automobile, dilation of the cervical vertebrae will not extend the physiological range. However, neck injuries are still occurring frequently as a result of the rear collision accidents. This paper describes an experiment simulating low speed rear impacts by using ten volunteers for the purpose of clarifying the neck injury mechanism. Data taken by using a continuous X-ray photographing device were analyzed. The following points were made clear on features of collisions from comparison with normal cervical vertebral behavior: at a rear impact, the cervical vertebrae are subjected to action of axial compression force due to inertia of the neck, in addition to push-up of the body resulting in upward movement, and the force remains affecting the cervical vertebral behavior thereafter; the effect appears as a bending condition in the cervical vertebrae in the initial stage around 50 to 100 ms after the impact, and then transfers into dilation behavior; and this condition exceeds the normal physiologically movable range, particularly the movement of the winding center being abnormal, which is thought to involve in the mechanism of generating injuries in vertebral joints. 8 refs., 11 figs.

    As a series of the studies on the mechanical properties of spider threads, the effects of ultra- violet rays (UV) and water was investigated using drag lines of Nephila clavata (Jorougumo) and capture threads of Argiope amoena (Koganegumo). It was shown for the effect of water that (1) the drag line was contracted as soon as immersed in water (super contraction), while the capture thread was not so contracted and the viscid droplets attached to it were dissolved in water, and (2) the super contracted drag fine behaved like a capture thread with a j shaped load-draw ratio curve. For the effect of UV, it was found that (1) the degradation due to UV irradiation with short wave length was accelerated more than that with long one and (2) the degree of degradation for each wave length was governed by the integrated irradiation energy of UV. 9 refs., 8 figs.

    Spider silk, differing to the synthetic fibers yarned at high temperature or using hazardous solvents, is a fiber in the body of animal and the process itself is safe. Again, the silk is made of up protein and is kind to the environment because does not cause pollution even after disposal. Also, it is a material of interest as a strong fiber having high tensile strength reaching to 2000 MPa. Accordingly, spider silk can be taken as an effective industrial material if the mass production of the fiber is possible by genetic engineering. In previous report, the mechanical properties of dragline silk spewed out from the same silk gland as the warp, a kind of silk spewed out by Nephila clavata, so called Jorogumo, were studied. In this report, the deformation behavior of circular net made by Jorogumo and applicability to environmental evaluation are under study, and effect of acid environment and ultraviolet rays on the mechanical properties of spider silk are studied. As a result, it was revealed that ultraviolet rays degraded the spider silk, and further, promoted the degradation when the acid rain acted at the same time. 16 refs., 11 figs.

    Study was made on improvement of the strength of silica aerogel as transparent insulating material. Silica aerogel is a low-density porous material with high heat insulation and transparency. To develop a insulating material with high transparency, monolithic silica aerogel was studied. For direct use of it for windows, its strength improvement was attempted. The aerogel was prepared by supercritical drying (alcohol or CO2) of silica wet gel obtained by hydrolysis and condensation of silicon alkoxide solution. To prepare the aerogel bonded on plate glass for strength improvement, the aerogel was bonded to alkoxide by exposing active silanol radical through F-etching of plate glass surface. However, to obtain the practical large-area bonded aerogel, shrinkage control of the aerogel in supercritical drying was necessary. Addition of Laponite into a silica network for strength improvement by polymer increased the bending strength by 50%. Although some reduction of its transparency was observed because of clouding, its heat insulation was stable. Further strength improvement is necessary for its practical use. 5 figs., 1 tab.

    Bottom plates of a hull are subjected to laterally distributing force due to in-plane compression force and water pressure in the ship`s length direction as a result of longitudinal bending in a hogging condition. Because buckling collapse of the hull bottom plates leads directly to longitudinal bending collapse of the hull bottom cross section, the hull bottom plates must have sufficient strength. The present study performs a static elastic large deflection analysis and an elasto-plastic large deflection analysis. It elucidates buckling collapse behavior of a square plate subjected to water pressure and in-plane compression load, and considers limits in application of conventional approximation analysis methods. In the case of a water pressure action, deflection components growing in excess of the buckling load do not necessarily correspond to buckling modes of the case where no water pressure is acting upon. Conventional approximation analysis methods may not be able often to pursue actual buckling phenomena. According the result of an analysis on hull bottom panels of an actual ship, the ultimate strength decreases when the water pressure is large. Compression force in the lateral direction as a result of water pressure acting on ship`s sides affected very little the ultimate strength. 3 refs., 7 figs.

    On the hydroelastic behaviors of a huge floating structure, a mutual interaction theory based on the area division method is used for the analysis of a fluid problem and a mode analysis method is used for the analysis of deformation. On the continuous deformation of a floating structure, the structure is considered as a set of partial structures obtained when the plane shape was divided into squares and discretely handled as a series of rigid motions in the small partial structures obtained by dividing the partial structures more finely. The experimental result in a water tank and the distribution method at a singular point were compared on the deformation of the elastic floating structure estimated by calculation based on this formulation. The result showed that the estimation method on the hydroelastic problem proposed in this paper is valid. On the prediction of hydroelastic behaviors of a huge floating structure, various calculation examples indicate that the hydroelastic behavior is not only the relation between the structure length and wavelength, but also that the bending rigidity of a structure is a very important factor. For a huge floating structure in the 5,000 m class, up to shorter wavelength of about {lambda}/L = 1/100 must be investigated. 6 refs., 14 figs., 5 tabs.

In this report, many informations were achieved from the fatigue crack propagation experiment under same load condition using center notched specimens for the three cases such as tension residual stress and compression residual stress are applied to the near edges of the specimen, and for the case where residual stress do not exist in order to study whether the stress expansion coefficient limit {delta}K{sub RP} corresponding to load range above RPG load can be a parameter of fatigue crack propagation rate or not even in case of residual stress field and further, whether the simulation of RPG load can be materialize even in case of residual stress field or not. 6 refs., 9 figs., 2 tabs.

    In the previous paper, a simulation model of fatigue crack opening and closing phenomena in an arbitrary stress distribution field for the purpose of obtaining RPG load is shown. From the calculation and experimental results of RPG load, the effects of stress ratio and delayed retardation on fatigue crack propagation are quantitatively assessed. Moreover it becomes clear that the stopping condition of fatigue crack propagation is {delta}K{sub RP}{le}0. In this paper, fatigue crack propagation tests in residual stress distribution field are carried out. Two types of center notched specimens are prepared: one is that gas heating is made at the center line of the specimen which leads to tensile residual stress field in the middle part of the specimen, the other at near the edges of the specimen which leads to compressive residual stress field in the middle part of the specimen. It becomes clear that tensile residual stress descends RPG load and compressive residual stress raises RPG load. Moreover if the large compressive residual stress exists, crack closes even when tensile yield zone generates at the crack tip under loading process. In this case, plastic zone could not grow until crack becomes fully open. Simulated RPG load is in good agreement with experimental one even in the field of residual stress distribution. And compressive residual stress has a large effect of decreasing the fatigue crack propagation rate. These effects can be successfully estimated by the simulation model. 6 refs., 9 figs., 2 tabs.

    Efforts are exerted to develop cushioning material (packing material) manufacturing technologies making use of low-grade wastepaper, to commercialize a low environmental impact type cushioning material, and to promote wastepaper recycling. Activities are conducted in the three domains of (1) the development of a technology for manufacturing a foaming eco-material out of magazine wastepaper, (2) the development of manufacturing equipment, and (3) a market survey. Crushed wastepaper in a gelatinous water solution is vigorously stirred for the gelatine to go into a crosslinking reaction, and is dried for the manufacture of a cushioning material (foaming material). In domain (1), technologies for controlling crosslinking reaction and physical properties are developed, and raw materials and target material manufacturing conditions are selected so that the product price will be not higher than the price of expanded polystyrene. In fiscal 2000, studies were made on wastepaper fiber composition, characteristics of a binder to use, and plant operating conditions, and a technology was developed that stabilizes the specific weight of the foam product at 0.10 or less. Foam products were manufactured by way of trial for use with domestic appliances and optical equipment. (NEDO)

In fiscal 1998, study was made on optimum alloy composition and heat treatment condition to obtain high-hardness steel with the performance over that of existing HSS by carbide dispersion carburizing process using conventional gas-carburizing facility, based on the data of phase diagram calculation. As a result, the composition and heat treatment condition necessary to obtain a target hardness of Hv1000 were determined.

In the study on motorized wheelchairs, a questionnaire was given on disorders, remaining functions and environment in which the wheelchairs would be used to select the most suitable formula from among 14 types of basic wheelchairs. After having adjusted the seat and operation lever positions for optimization by using a specific wheelchair for measurement, the power was so outputted that image illustrations after values have been inputted can be checked on the screen. In studying a travel support system, based on the fact that anomaly has occurred in operation of the boarding and alighting device during a test by a third party laboratory, a review was given on the capacity of the device. As a result of changing the motor to the one higher by one rank, the required time was decreased by 25%. In addition, the boarding direction was limited to one direction, and the reverse speed was changed and improved to 60% of the forward speed. In developing the total system, studies were made on methods of binding, and methods of protecting surrounding environment. (NEDO)

    To cope with the global warming caused by CO2, an investigation was conducted into biological fixation. It is necessary to make a many-sided and comprehensive study on the mechanism of CO2 fixation, the scale (area and carbon holding density), the rate and the environmental impact of the introduction of the technology and the technical problems, and to make a quantitative evaluation of each of the methods in order to make them practical proposals. The global ecosystem is classified into the land biota and ocean biota, and each typical ecosystem was surveyed in terms of the surface area, the carbon holding amount (presently existing amount), the net primary production amount, the required nutrient salt amount, the transpiration rate, etc. Next, a discussion was made on the increasing effect of the carbon fixation amount by changing the present ecosystem from the aspect of scale and rate. At the same time, a study was carried out of energy efficiency, economical efficiency and problems. Last, elementary technology was taken up which seems to be important for implementing measures for the biological carbon fixation. As to the ocean, it is necessary to obtain information, which is not sufficient to utilize marine biota for CO2 fixation, especially on the mechanism of depth-direction transfer of organism and its quantitative grasp. As to the land, one of the measures is conversion of the ecosystem where the amount of carbon fixed is small to the ecosystem where the amount is large. 249 refs., 58 figs., 51 tabs.

    High temperature and high pressure steam has been investigated for the high efficiency waste power generation technology development. The steam temperature below 300 centigrade is currently employed to avoid the corrosion of superheater, and the generating efficiency is less than 15%. Practical application of 500 centigrade and 100 kg/cm{sup 2} is planned by developing corrosion resistance materials. Environmental load reduction technology has been also developed. For the external circulation type fluidized bed furnace combustion tests using dummy waste in fiscal 1995, the temperature control at bag filter was effective for suppressing the dioxins. When using waste plastics, HCl could be reduced by blowing Ca compounds. Various Cr-Ni-Mo-based alloys have been developed as a corrosion resistance superheater tube material, and are currently tested. For the environmental load reduction technology, the development of pulse plasma exhaust gas treatment method has been continued from fiscal 1993. In fiscal 1995, this method was confirmed using a small-scale test unit, and also tested using a 5000 Nm{sup 3}/h bench-scale unit. The removal rates of dioxins at the outlet of bag filter were 99.8% and 99.3%, respectively. They were found to be affected greatly by the pulse waveform. 13 refs., 107 figs., 24 tabs.

    Research and development is carried out to help aged people get employed in manufacturing industries. Important problems to solve before they can work in the field of fabrication or assembling involve deterioration in working environment recognition capability due to poor eyesight, reduction in work efficiency due to muscular weakness, and degradation in work precision due to quivering fingers, all these attributable to disfunction typical of advanced age. Accordingly, it is deemed that experienced old people's skill will be fully made use of if their deteriorated sensing and manipulating capabilities are mechanically supplemented. In this research, basic studies are conducted concerning a workpiece position/attitude recognition system for supplementing poor eyesight and an operation type manipulator capable of providing the sense of force. In the study of the recognition system, a method is considered, in which the selection of the necessary workpiece is dependent on the worker' ability and the position/attitude of the selected workpiece is measured by a sensor. In the study of the manipulator, a method is considered, in which the handling of the workpiece is performed by a manipulator similar in structure to that of an industrial robot and an active joystick is used to indirectly handle the workpiece. In fiscal 1998, designing and tentative fabrication are launched. (NEDO)

    In order to clarify the dynamic characteristics of a self-controlled Darrieus-Savonius hybrid wind turbine system, a system consisting of a hybrid wind turbine and an AC generator was tested under various wind conditions in the wind tunnel. We took up four types of wind blowing change for the test; ramp, sinusoidal and square wind velocity changes and a similar wind velocity change to the field wind. A series of tests substantiated the effectiveness of our operating scheme wherein the tip speed ratio is maintained at a constant value. On the other hand, theoretical studies have been carried out on the characteristics of the system. A simulation model is presented in order to describe the system characteristics not only for the steady-state behavior but also for the dynamic behavior. In spite of its simplicity, the model can predict both characteristics of the system well. The appropriateness of the simulation model is confirmed by comparing with the experimental results. -In addition, the field test data are discussed. As a result, it is confirmed that the system is operated and controlled satisfactorily in the field. 14 refs., 19 figs., 3 tabs.

    Concrete strength varies in accordance with material proportioning and age, and is usually mixed and designed at the determined age in order to manifest the specified strength. Concerning high strength concrete with design strength over 360kg/cm{sup 2}, however, there is no clear provision to estimate increse and deviation of the strength in the case where either age or cumulative temperature varies. In this study, the strength and the distribution of standard curing concrete and concrete after long piriod of time were measured and analyzed statistically in regard to 14 kinds of high strength concrete with the nominal strength between 360 to 465kg/cm{sup 2} of three construction projects. Considering that strength ratio of concrete at two different kinds of cumulative temperature showed the nominal distribution, a method to predict the strength distribution of concrete after a long period of time was presented. In this method, for instance, use of such parameters as standard deviation of strength on the 28th day of age and strength index could make it possible to predict the average strength and the standard deviation at different ages. 9 refs., 15 figs., 6 tabs.

    Discussions were given on practical application of a stress analyzing method for thin-wall deformed cross-sectional beam considering cross section camber in longitudinal bending. The non-static calculation method described in the previous report can be applied to a box-type cross section having multi-connected cells, bulk cargo transport vessels and container ships with dual hull structure, and oil tankers with dual hull structure of medium size. The calculation method was capable of achieving remarkable enhancement in efficiency over that of conventional calculation methods. The present study is intended to make the method applicable also to multi-connected cross section shapes having more than one longitudinal partitions as used in dual hull VLCC and ULCC. As a result, an expanded non-static calculation system was developed, which has introduced into the conception described in the previous report a new conception of triple point and independent start point members. As a result of applying the method to dual hull bulk cargo transport vessels, container ships, dual hull oil tankers of medium size, VLCC and ULCC, it was verified that the system operated properly. Remarkable efficiency improvement has been made possible as compared with conventional analysis methods applied to individual ships. The system is capable of automatic calculation, and makes possible the practical application of the hull strength theory considering cross section camber. 3 refs., 10 figs., 1 tab.

    The concentration of excited oxygen ([sup 1][Delta]g), which was generated by microwave discharge in a pure oxygen flow, was measured from the intensity of spontaneous emission. The conversion factor to density was determined by spectroscopic analysis of the rotational structure and calibration of the emission intensity using a black-body furnace as light source. Consequently, a good agreement was found between the observed profiles and those calculated from spectroscopic data, and it was illustrated that the absolute concentration can be obtained by coupling band analysis and the calibration method. In addition, even when the concentration was low, it was shown that the excited oxygen concentration can be measured by considering the reflection at the cell wall. The excited oxygen concentration at the microwave discharge cavity was estimated to be around 1% under the pressure ranging from 0.5 torr to 2 torr. Furthermore, the comparison of the profiles calculated at different temperature provided that the band profile can be a good indicator of gas temperature when the signal-to-noise ratio is high. 9 refs., 10 figs., 2 tabs.

    The deformation mechanisms of submerged shell-like lattice structures with membrane are in principle of a non-conservative nature since the follower type hydrostatic pressure. In the region of large deformations, especially in the case of geometrically deep shell-like lattice structures, the system could be much more accurately defined in a mono-clinically convected coordinate description than the conventional spatial description. Also, a complete analysis of a non-conservative system requires a criterion since the system can have multiple ranges of stability and instability involving buckling and snapping. This paper presents the development of the governing equations for the finite deformations of shell-like lattices defined in a mono-clincally convected coordinate description and applies the same to different cases of lattice deformations. The validity of the formulations is verified for finite deformation. The examples of some geometrically special shell-like lattice structures are presented as well to show the feasibility of the present formulation. 5 refs., 11 figs.

    Buckling and plastic breakdown strength characteristics of a structure fabricated by using new steel plates with surface layer made into ultra fine grain structure were analyzed and discussed by using a belt plate buckling and plasticity test and the finite element method. The tested steel plate has a thickness of 25 mm, and was fabricated for ocean vessel use, with surface layers on both sides of about 1/6 of the whole thickness having been made an ultra fine grain structure. As a result of a belt steel buckling and plasticity test on a steel plate with surface ratio of 29%, both of the initial yield stress and the buckling stress were found increased by about 4 to 10% as compared with a steel plate having surface ratio of 0%. An analysis by using the finite element method was made on square steel plates with a length of 80 cm, a width of 100 cm, and thicknesses of 12 mm and 24 mm. A result was obtained that, in the case of surface layer ratio of 33%, both of the initial yield stress and the maximum load withstanding force were higher by 5 to 16% than the case of surface ratio of 0%. Similar rise in strength was shown also in bend preventing plates which are basic constituting members of a vessel. 6 refs., 10 figs., 2 tabs.

    Pretreatment of brown coal in oil was conducted using 1-methyl naphthalene or mixture of tetralin and 1-methyl naphthalene as solvent at temperatures ranging from 300 to 430{degree}C under nitrogen atmosphere. Effects of the solvent properties on the structural change of oxygen-functional groups (OFG) and coal liquefaction were investigated by means of quantitative analysis of OFG and solid state {sup 13}C-NMR measurement. When hydrogen transfer from solvent was insufficient, it was suggested that brown coal molecules loose their hydrogen to be aromatized. While, at lower temperatures ranging from 300 to 350{degree}C, hydrogen contained in brown coal molecules was consumed for the stabilization of pyrolytic radicals, and the deterioration of liquefaction was not observed. When hydrogen transfer from solvent was insufficient at higher temperatures above 400{degree}C in nitrogen atmosphere during pretreatment in oil, crosslinking like benzofuran type was formed by dehydration condensation of hydroxyl group in brown coal, to deteriorate the liquefaction, remarkably. The addition of donor solvent like tetralin decreased the formation of crosslinking like benzofuran type, which suppressed the deterioration of liquefaction. 8 refs., 5 figs.

    In relation to coal liquefaction reaction, the effect of the coexistence of transferable hydrogen (TH) from process solvent on reduction of radical concentration and the effect of pre-heat treatment on average structure of coals were studied. In experiment, change in radical concentration with temperature rise was measured using the system composed of Yallourn coal and process solvent. The results are as follows. Process solvent with a wide boiling point range of 180-420{degree}C is effective in suppressing an increase in radical concentration even at higher temperature. The effect of hydrogen-donating solvent increases with TH. It was also suggested that high-boiling point constituents in solvent stabilize radicals even over 400{degree}C by vapor phase hydrogenation. The experimental results of pre-heat treatment are as follows. Although the conversion improvement effect of TH is equivalent to that of the model solvent, TH tends to produce soluble products with smaller ring numbers. It was thus suggested that pre-heat treatment in process solvent is effective to inhibit retrogressive reactions. 6 refs., 5 figs., 1 tab.

    As part of the studies on coal utilization basics, considerations were given on quantification of sulfur forms of coal and the pyrolysis behavior of sulfur compounds. With the temperature raising oxidation method, a thermo-balance was connected directly to a mass analyzer, and the coal temperature was raised at a rate of 5{degree}C per minute and gasified. Peak division was performed on SO2 and COS production to derive sulfur forms of coal. Using the slow-speed pyrolysis method, production rates of H2S, COS, SO2 and mercaptans were measured at a temperature raising rate of 20{degree}C per minute. Sulfur content in char was also measured. With the quick pyrolysis method, a Curie point pyrolyzer was connected directly to a gas chromatograph, by which secondary reaction is suppressed, and initial pyrolytic behavior can be tracked. All kinds of coals produce a considerable amount of SO2 in the slow-speed pyrolysis, but very little in the quick pyrolysis. Instead, H2S and mercaptans are produced. Sulfur compound producing mechanisms vary depending on the temperature raising rates. By using a parallel primary reaction model, analysis was made on reactions of H2S production based on different activation energies, such as those generated from pyrite decomposition and organic sulfur decomposition. The analytic result agreed also with that from the temperature raising oxidation method. 4 refs., 6 figs., 1 tab.

    The January 17, 1995, Hyogo-ken Nanbu earthquake was occurred. This earthquake was the most damaging earthquake to have struck Japan since the great Kanto earthquake. In Los Angela area, the Northridge earthquake was occurred at January 17, 1994. In this earthquake, the large acceleration over 1G was observed. Two base-isolated buildings (computer center and research facility) in Kobe-city, and USC Hospice (base-isolated building) in Los Angeles survived these big earthquakes. In this paper, the observed response of these base-isolated buildings was introduced and the performance of base-isolated buildings was discussed. And the dynamic response analysis was carried out using the observed ground motions during the two big earthquakes. As the results, the acceleration response of base-isolated buildings which isolated period Tf is over 4 sec was below 0.1-0.2G, and the relative displacement of isolated story was under 30-50cm. 13 figs., 4 tabs.

    A theoretical study was conducted to investigate the wetting behavior of liquid meniscus on a vertical plate with three-dimensional random characteristics of heterogeneity and roughness. The thermodynamic stable condition was derived by considering the minimum of system free energy. The local stable condition leads to a result similar to that obtained for a plate with two-dimensional characteristics, i.e., the system has many meta-stable states. For the stable condition of the whole system, a relation was derived between macroscopically observed contact angle and the surface characteristics. The product of cosine of the contact angle and liquid surface tension is equal to the energy difference for the liquid to wet the plate by apparent unit area. If the liquid wets the solid surface reversibly, there is only one contact angle observed macroscopically. This fact suggests that the contact angle hysteresis is caused by the irreversible motion when the liquid advances or recedes on the solid surface. The well-known Cassie and Wenzel's contact angles are explained as those corresponding to thermodynamically stable condition when the liquid wets the solid reversibly. (author)

    The past study of safety at vehicle collision pays attention to phenomena within the short time from starting collision, and the behavior of rollover is studied separating from that at collision. Most simulations of traffic accident are two-dimensional simulations. Therefore, it is indispensable for vehicle design to the analyze three-dimensional and continuous behavior from crash till stopping. Accordingly, in this study, the three-dimensional behavior of two vehicles at collision was simulated by computer using dynamic models. Then, by comparison of the calculated results with real vehicles` collision test data, it was confirmed that dynamic model of this study was reliable. 10 refs., 6 figs., 3 tabs.

    A very large floating structure was replaced with the beam on an elastic foundation to examine the response characteristics in waves. Another evidence was regularly and numerically given for the basic characteristics of a very large floating body Suzuki found. New information was also obtained. The frequency response is mainly classified into a wave number control area and proper frequency control area when buoyancy elasticity exists. When the buoyancy structure is long and flexible, the proper frequency becomes continuous and the frequency control area becomes a resonance area. In the wave number control area, the Suzuki`s characteristic wave number becomes a control parameter, and various characteristic values are indicated by characteristic wave numbers. The response in the wave number control area becomes quasi-static when the distribution mass of buoyancy is fully small. The design in which the distribution mass of buoyancy is fully large must be avoided. In the displacement amplitude, the mass on the free end is severest. The proper frequency of vertical vibration relatively moves to the high-frequency side when buoyancy is considered as an elastic foundation. Attention must be thus paid to the proper frequency of vibration on the horizontal surface. 9 refs., 12 figs., 3 tabs.

    As surface treated steel sheets, steel sheets with Zn-Fe coatings as well as double-layer steel sheets with Fe-P alloy coatings on Zn-Fe alloy coatings are often used practically. Two treatment methods, which are used to dissolve only alloy layers without dissolving steel sheets in order to find amount and composition of alloy layersr have already been reported. This report investigates the mechanisms of these methods, particularly the mechanisms to control dissolution of steel sheets. In the alkali-dissolution method, Zn-Fe alloy coatings are dissolved in a strong alkaline solution(NaOH-triethanolamine (TEA)-H{sub 2}O{sub 2}). In this case, steel sheets are insoluble because passive films are formed on the surface. In the cathodic polarization electrolysis method, alloy layers are electrolyzed({minus}l.2V) and dissolved in an ammonium nitrate-0-phen electrolyte. At this potential, dissolution of steel sheets can be prevented by the 0-phen films adsorbed on the surface. Consequently, the alkali-dissolution mehtod and the cathodic polarization electrolysis method are applicable to the quantitative analysis of Zn-rich layer (Fe is 40% or less) coatings and that of Fe-rich layer(Fe is 70% or less) coatings, respectively. 18 refs., 8 figs., 7 tabs.

    The spheroidal graphite cast iron is better characterized in resistivity against the abrasion and heat, and economical efficiency than the normal carbon steel. Notice being taken of treatment temperature (800 to 840 centigrade) in the ({alpha}+{gamma}) phase region for the partial austempering treatment condition, able to improve the spheroidal graphite cast iron simultaneously in both statical tensile characteristics and fatigue crack propagation resistance, the present report compared dual phase as-cast material, single phase ferrite and single phase bainite. As a result, the morphological ratio of bainite becomes about 20% to the base morphology at 800 centigrade in treatment temperature. Then with progressively heightening to 815, 830 and 840 centigrade in it, the above ratio so heightens to about 40, 80 and 90%, respectively. The fatigue crack propagation resistance in the low DeltaK (low stress intensity factor) region is heightened by the partial austempering treatment to higher than that of dual phase as-cast material, single phase ferrite and single phase bainite, and most done at 800 centigrade in temperature where the bainite becomes about 20% in morphological ratio. 830 centigrade where the bainite becomes about 80% is judged to be the most appropriate treatment temperature for both the statical tensile characteristics and fatigue crack propagation resistance. 3 refs., 16 figs., 3 tabs.

    Transformation characteristics and deformation behavior of Ti-50.5at%Ni shape memory alloys, which were occluded hydrogen in various levels, were investigated through electrical resistivity measurements, tensile tests, and X-ray diffraction. Specimens were heated in a low pressure range of hydrogen between 1.1 and 78.5kPa for equilibrium, and thus obtained the specimen which occluded hydrogen up to a maximum value of 5.6 mol%. Martensitic transformation starting temperature(Ms) decreased with an increase in hydrogen content. This corresponds to the fact that the improvement of stabilization of the parent phase during cooling due to hydrogen occlusion was confirmed by X-ray diffraction. It also shows that hydrogen has the suppression effect on this deformation. Critical stress for slip deformation changed with hydrogen content so that hydrogen influenced greatly on deformation behavior of the alloys. Lattice softening occurred with hydrogen contents up to 0.032 mol%, and changed into hardening above 0.032 mol%. Hydrides formed with hydrogen contents over 1.9 mol% resulted in reorientation in variants of the R phase and an increase in lattice strains of the parent phase. 29 refs., 14 figs., 1 tab.

    The toughening mechanism by stress-induced transformation in partially stabilized zirconia has been proposed by McMeeking,et al. However, their model is not coincident with the experimental data on Ce-TZP by Yu, et al., because it is assumed that the transformation volume fraction of the former model is low and the stress field is formed only at the main crack tip. In this paper, it is considered that the stress field is formed not only at the main crack tip but also by transformed particles with expanded volume. Consequently, numerical simulation of the shape and width of the transformed zone and R-curve behavior in partially stabilized zirconia was carried out. As a result of analyses, the formation process of the transformed zone was divided into two types due to transformation volume fractions. In the case of the low transformation volume fraction, the R-curve behavior agrees with the analysis by McMeeking et al., and the width of the transformed zone does not change even with crack extension. In the case of the high fraction, however, change in the shape and extension of the width of the transformed zone occur discontinuously along the crack extension. It shows a step-like R-curve behavior. 10 refs., 10 figs.

    Discussions were given on effects of welding heat cycles on transformation behaviors in a weld heat affected zone (HAZ). Test pieces are low-carbon fine ferrite pearlite organization steel sheets, which have been treated with a thermomechanical control process (TMCP). The heat cycling was experimented at a maximum temperature of 1350 degC by using a high-frequency heating coil, heating rates from 0.15 to 200 degC/s, cooling rates from 10 to 80 degC/s at an elevated temperature region (higher than 900 degC), and transformation regions (lower than 900 degC) from 0.5 to 6 degC. A transformation curve in actual welding heat cycling was interpreted from these results. Shear-type inverse transformation (from ferrite to austenite) occurs in a rate region corresponding to the heating rate realized during welding. Austenite containing internal stress and a lower structure formed by this inverse transformation accelerates transformation into grain boundary ferrite (GBF) and acerous ferrite (AF). On the other hand, slow cooling in the elevated temperature region releases the internal stress, restores the lower structure, and suppresses the GBF and AF transformation. The GBF tends to precipitate pearlite in adjacent regions and deteriorates the HAZ tenacity. 17 refs., 8 figs., 1 tab.

    The thermomechanical hysteretic behavior of an Fe-based shape memory alloy is phenomenologically analyzed under cyclic uniaxial tensile and compressive loading. The shift of the stress-strain-temperature hysteresis loop, expressed by means of the evolution of the residual strain, is well explained by the theory with some internal variables. The accumulated perfect dislocations formed as a result of the interaction of martensite plates is one of the internal variables introduced here. The back stress is also employed as an internal variable to be the driving force for the shape recovery for the martensite plates. The simulations describe well the hysteretic behavior under the strain and stress-controlled cyclic thermomechanical loading; the shift of a loop, evolution of the residual strain and the change in transformation stress. 21 refs., 10 figs., 1 tab.

    In a long-span suspension bridge having a stiffening truss, a large angular bend of a hanger occurs due to the relative displacement of a main cable and a stiffening girder occurring during a storm. This paper describes the production of a life size specimen with importance attached to a fixed portion of a one-way pin which is in a severe stress condition, and the measurement of the stress condition of a fixing plate and a reinforcing plate near a pin hole of a pin fixing structure, the contact condition of the pin with the pin hole and the bending stress of the pin. The paper further describes a fatigue test conducted in a stormy weather condition. The results of an investigation into two types of contact condition of the pin and pin hole clearly show that the pin is in a one-side contact state during a storm, not in a uniform contact state even in a normal condition due to the unevenness of the inner surface of the pin hole. Therefore, the load of the hanger is not evenly transmitted to the connection plate and reinforcing plate. Consequently, it is necessary to discuss in the future the size and quality of a weld at which the connection plate and reinforcing plate are joined together so as to attain reliable transmission of the load. 4 refs., 14 figs., 2 tabs.

    A hull structure is constituted by thin panels, and reinforced longitudinally and laterally by stiffened members to increase the effectiveness of the structure. In order to attain findings on buckling and plastic collapse behavior of stiffened plates, this paper describes analysis of elasto-plastic large deflection by using the finite element method on thin stiffened plates having flat-bars and angle-bars. The analysis includes the case of an aspect ratio being 5.0 and the case to consider welding residual stress. Considerations were given on cross sectional shape, panel aspect ratio and effects of initial welding imperfections against the buckling and plastic collapse behavior of the stiffened plates. The angle-bars tend to cause secondary buckling more easily because it has greater bending and twisting rigidity, and stronger constraint against deflection than the flat-bars. When the aspect ratio is larger and the span is longer, the ultimate strength declines, and the withstand power after the ultimate strength decreases rapidly. Existence of the residual stress tends to make the secondary buckling occur more easily. The secondary buckling affects little the withstand power after the ultimate strength. 3 refs., 7 figs., 1 tab.

    Data for large giant oil fields with minable reserves of one billion barrels or more were accumulated to structure a new oil field depletion model and estimate production in each oil field. As a result of analyzing events recognized in large giant oil fields, necessity was made clear to correct the conventional oil depletion model. The newly proposed model changes definitions on the depletion period of time, depletion rate, build-up production (during a time period in which production rate increases) and production in a plateau (a time period in which production becomes constant). Two hundred and twenty-five large giant oil fields were classified into those in a depletion period, an initial development phase, and a plateau period. The following findings were obtained as a result of trial calculations using the new model: under an assumption of demand growth rate of 1.5%, oil field groups in the initial development phase will reach the plateau production in the year 2002, and oil fields in the depletion period will continue production decline, hence the production amount after that year will slow down. Because the oil field groups in the plateau period will shift into decline in 2014, the overall production will decrease. The year 2014 is about ten years later than the estimation given recently by Campbell. Undiscovered resources are outside these discussions. 11 refs., 9 figs., 2 tabs.

    Observation of the enameles interface with SEM, EPMA and ESCA, and measurement of adhesive strength of the enameles were done. Simultaneously, cobalt and nickel in the enamel layer examined a given influence at the interface and the adhesive strength. As a result, the relationship between iron-oxygen, cobalt-oxygen and nickel-oxygen, at the reaction of enamel process was explained by the interface thermodynamics. Furthermore, characteristics and differences of reaction of cobalt and nickel were clarified. (1) The adhesive ability of Co-enamel was larger than that of Ni-enamel. (2) The adhesive behavior of cobalt changes at about 730degC, but that of nickel remains unchanges. Consequently, cobalt has an adhesion with the high temperature (over 730degC) but nickel does not have an influence on the temperature. (3) At high firing temperature, the Co-enamel can create FeO easily compared with Ni-enamel, and dissolve Fe{sub 2}O{sub 3} of steel surface into glass. (4) Cobalt spreads for a vertical direction of interface, but nickel tends deposition on the interface surface. And the diffusion capability of cobalt into the steel was considerably greater than that of nickel. 18 refs., 7 figs., 3 tabs.

    This paper reports the result of observation using the Schlieren method on how temperature boundary layer changes when an electric field is applied in boiling heat transfer. The experiment used a fine nichrome wire in water as a heat generator. The electric field was built by placing a nickel rod as an electrode placed obliquely above and parallel with the heat generator, and applying electric potential to the electrode. The temperature boundary layer produced near the heat transfer face is disturbed by the electric field. The stronger the electric field, the more vigorous the disturbance. The turbulence in this boundary layer is relatively regular, and observed as stripes of temperatures. The stronger the electric field, the more the number of the stripes in the temperature boundary layer, and the higher the stripe density in the axial direction of the heat generator where the temperature difference appears. Boiling bubbles, occurring when the electric field is applied, are kicked out of the temperature boundary layer that varies due to the electric field force, and the bubbles grow thereat. The turbulence is caused by the low-temperature high-density liquid impinging the heat transfer face perpendicularly as a result of the electric field force, and changing its place vigorously with low-density liquid in the boundary layer. 6 refs., 16 figs.

    In order to improve the gas turbine blade film cooling technology, this paper elucidates flow field and temperature field of secondary air blown out into a span direction; derives the temperature distribution on the wall face; and describes cooling air behavior in film cooling. The wall face temperature distribution measured with a temperature measuring system using liquid crystal has shown relatively good correspondence with the temperature distribution in the vicinity of the wall face as measured by a two-wire probe. Film cooling by blowing air into the span direction has shown good attachment of the secondary air onto the wall face in the secondary air blowing direction. However, in the opposite direction to the air blowing direction, air has attached to the wall face only poorly because of vortex movements of the primary air due to being dragged in. The secondary air has departed from the wall face as the blow-out ratio has been increased, resulting in drop in the cooling efficiency. A 'Z' direction position that the temperature of the secondary air shows a maximum value differs from a 'Z' direction position having a peak in the wall face cooling efficiency, the difference having become more noticeable with increasing blow-out ratio. A region with lower cooling efficiency due to rolling-in of the primary air exists near the blow-out hole, where rolling-in of the primary air is recognized prominently as the blow-out ratio has been increased. 8 refs., 6 figs.

    A tendency of gradual extinction of disasters caused by the breaking of loose stones and falling rocks in limestone mines and quarries is brought by the improvement of safety control against slope accidents in these years. In this study, in order to examine the accumulation of data contributing to the countermeasure against falling rock in strip mines, the movement of rocks in an open-shooting quarry were shot by video cameras and analysed to clarify the behaviors of falling rock. The following results are obtained. It is found by observing falling rocks from a slope side that the value of falling velocity is getting smaller in an order of block-shaped, tabular and stick-shaped rocks. In the case of tabular rock, there is a tendency that the velocity distribution has two peaks. Not only the falling velocity but also the rolling velocity of block-shaped rock is smaller than those of block-shaped and tabular rock. Further, values near the supremum of actually measured values can be given by a rolling velocity equation wherein the shape of falling rock is assumed as orbicular. If setting it forth as a premise, said equation is possible to be used for estimating rolling velocity. 24 refs., 20 figs., 2 tabs.

    For candidate materials of the ultra super critical (USC) turbine rotor in a coal fired power plant, the modified 12Cr steel and A286 steel are subjects of the study under the first step steam condition (316 atg, 593 centigrade) and under the second step steam condition (350 atg, 650 centigrade), respectively. The strength evaluation tests of the modified 12Cr steel untreated material and aging (630 centigrade, 4860 hours) material I were conducted previously, and obtained a prospect that the material can be applied to the first step turbine rotor. In this report, the strength evaluation tests and microstructure observation of the long period aging (630 centigrade, 8190 hours) material II, and the strength tests of the A286 steel have been conducted. As a result, it was found that the modified 12Cr steel is a stable material in the microstructure and has enough strength characteristics to apply the first step rotor, and the A286 steel also can be applied to the second step rotor. 9 refs., 27 figs., 8 tabs.

    A technique to analyze the ground behavior in shield tunnel work by use of the finite element method in consideration of the construction process is suggested. It is shown that the analysis of excavation of a shield machine with use of the force of jack propulsion is possible by modelling the excavating situation of the shield machine by arranging excavating elements in the assumed region where the ground is disturbed by excavation in front of the cutting face of the shield machine and re-dividing the excavating element and ground element for each calculation step. Succeedingly it is described that a shield work made in alluvial cohesive clay in the suburbs of Tokyo was applied with three-dimensional elasto-plastic finite element analysis which models the situation that the shield machine is driven by jack propulsion force while taking the ground in front of the shield machine into the machine, and, as a result of this, a result of calculation close to the observed results in the construction was obtained concerning the situation of displacement of ground and varying conditions of the posture of the shield machine and the hydraulic pressure of gap. 14 refs., 15 figs., 2 tabs.

    V-belts are widely used for driving auxiliary components of an engine. Inadequet design of such belt system sometimes results in troubles such as belt squeak, side rubber separation and/or bottom rubber crack. However, there has been no design tools which can predict belt slip quantitatively. The author developed a motion simulation program of Auxiliary Drive V-Belt System considering belt slip. The program showed good prediction accuracy for belt slip motion. This paper describes the simulation model. 1 ref., 12 figs.

    Described herein are the results of the FY1994 research program for international joint technology development for solar energy utilization systems. The joint study with an Indonesian research institute takes a model of lumber drying plant for the design and feasibility study. All the parts it needs are technically available in Indonesia, except carbon fiber sheets and electronic devices for controlling purposes. The drying cost is higher than that of a plant which procures charge-free wood fuel, but lower than that of a plant which procures fuel at 30$/t. A cacao drying plant model is also studied. The feasibility study shows that the initial investment for the blowing-up model is much higher by 60% to 100% than that for the conventional plant. Its fuel cost is lower by 11% than that of residual oil but 27% higher than that of wood. 4 figs.

    Studies are made of optimum materials and methods for manufacturing low-carbon fuels for reduction in greenhouse gas emissions. When their thermal dynamic limits and the technological maturity are considered, it is inferred that no extensive improvement will be achieved by merely improving on the efficiency of the existing fuels. The use of various high-efficiency driving power sources utterly different in mechanism from the conventional ones, such as those for fuel cell-powered automobiles, and the promotion of the use of low-carbon fuels such as methanol and methane for all kinds of driving power sources including those for the said fuel cell-powered automobiles, will become necessary. The use will also be necessary of recyclable materials. The biomass resources, in particular, since they absorb CO2 gas in their growing process by virtue of photosynthesis, may be said to be free of CO2 gas emissions. They have their own problems, however, which involve the economy of energy consumed for their production, harvesting, transportation, and conversion into fuels. It is therefore required that their whole life cycle be studied before their greenhouse gas reduction effect may be correctly assessed. The quantities of resources available for the production of automotive low-carbon fuels, manufacturing technologies, etc., are first of all put in order for easy perusal. An effective way is assessed for the whole including the life cycle. (NEDO)

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

    In the last twenty-five years, the level of social recognition for the importance of energy conservation grew progressively from a total nonexistence of concern to the driving force that ensures the future environmental health of the nation and the world. Executive Order 12003, relating to energy policy and conservation, was signed by President Jimmy Carter and dated July 20, 1977. In 1992, President Clinton issued Executive Order 12759 - federal Energy Management. Each agency will prescribe policies under which its industrial facilities in the aggregate increase energy efficiency by at least 20% in fiscal 2000 in comparison to fiscal 1985. Current Federal programs for building efficiency are estimated to result in 31.5 billion dollars in annual energy saving for consumers by 2010. Future trends attract attention. The major programs currently in force to implement these policies and directives include Rebuild America, Million Solar Roofs Initiative, Home Energy Rating Systems, and Weatherization Assistance Program. 37 refs., 1 fig., 6 tabs.

    The paper reported the general training of the fiscal 1996 coal engineer training program supported by NEDO. In Japan, where natural resource is poor, it is important to transfer from its petroleum dependence energy structure to the system for new energy development and dispersed energy supply. Coal resource is distributed widely in the world and is expected to spread in the future as a main substitute for petroleum. Worldwide attention is much paid to coal supply/demand and environmental problems, but the situation surrounding coal is not necessarily favorable. Under these conditions, Japan is a prominent coal importing country and is on the world-top level in terms of coal utilization technology. Japan has heavy responsibility and needs to play a leading role in adjusting and solving various problems on coal both domestically and internationally. Under the circumstances, 7 persons who are engaged in the coal related business and expected to be in future (3 from the mining relation and 4 from electric power comapanies) participated in the training this fiscal year and received the top-level training in Japan and overseas. 20 figs., 3 tabs.

    This paper describes the report on the survey in fiscal 1998 for preservation of Jozankei Spa (the second report). The hot spring area is located on the periphery of relative elevation area on the western side of a fault growing on the boundary of dikes constituting the lower part of the Jozankei quartz porphyry, with the fault forming a boundary. The fault peripheral beds have cracks develop nearly parallel to the fault. The low specific resistance anomaly extracted at underground depth from 100 to 500 m in the area south of the hot spring gushing area forms the clay alteration zone around the hot spring water and cracks arising from the opening type cracks formed around the weak lines of dikes, faults, and surface of unconformity. The hot spring originated water having risen and passed through fractures from deep underground section stagnates in these crack groups, and forms hot spring aquifer. The water is considered to have such nature as temperature of 120 degrees C, chlorine at 1,600 mg/l and tritium concentration of 2.1 to 2.5 TU. The water is characterized by eluation constituents from the Usubetsu bed. The hot spring water in the aquifer rises passing through the opening cracks in the upper part, wherein the water not mixing with ground water does not have the constituents change, and the mixed water changes the nature of the hot spring water. In the surface layer, the water flows through intersecting joints growing around the fracture, and gushes out of the ground. (NEDO)

    For diffusion of waste power generation, cost reduction is important. As the profitability evaluation technique for conventional waste power systems, a simple recovery year method, total waste treatment cost method, generation cost method, and evaluation method by accumulated balance sheet are presented along with their principles. For the generation cost method, trial calculation results are presented based on documents reported. From methods for the study in Institute of Applied Energy, some estimation methods of construction cost are presented, and generation cost and profitability evaluation were studied by parametric accumulation method. The profitability was calculated for RDF power systems, and it was clarified that although as a whole this system is more efficient than a simple refuse incineration system, the balance sheet of local governments is dependent on a responsibility range for the facility. In a combined type (super refuse power generation), generally municipalities bear a combustor and boiler, while a prefecture bears generation facilities. Because of large scale generation, the profitability is dependent on a selling price of electricity. 37 refs., 36 figs., 24 tabs.

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

    The amount of energy in existence is theoretically the amount of energy that exists in a given region while the available amount is an amount of energy worked out with technological, economic, and social conditions taken into consideration. The total of the amount in existence and that of the available amount are mentioned in a table, and the available amount is further shown in terms of calorie. It totals 11,120Tcal per year, which is equivalent to approximately 55% of the whole amount of energy that Tokushima Prefecture demands. The availability of each type of new energy and the state of development of related technologies are studied to determine what priority is to be given to what energy. The group that is given the highest priority consists of photovoltaic power generation, passive solar systems, refuse fueled power generation, and heat from wastes (this group occupying more than 80% of the available amount in Tokushima Prefecture). The second group consists of wind power generation, clean energy vehicles, cogeneration, and small and medium scale hydroelectric power generation. The third group consists of fuel cells, ocean energy, biomass, and temperature difference energy. Natural conditions surrounding new energy in existence in Tokushima Prefecture are rather favorable, but social conditions are not. (NEDO)

    For development of production technologies suitable for environment, safety and advanced information-oriented society by improving the flexibility of production lines, some new measurement technologies were researched. Problem solution was attempted by combining the in-situ multi-dimensional measurement technology capable of easily obtaining various 3-D information with the non-contact photon measurement technology superior in operability and sensitivity under any environment conditions. This solution requires a compact radiation source with higher brightness and wider spectral range, and a high-sensitive detector. The technology concentrating photon onto minute regions, high-efficiency transmission, and control technology of photon wave front are also necessary. Development and international standardization of a common interface is unavoidable. In addition, its network is essential for advanced use of multimedia,. In the future, the comfortable life surrounded by advanced products and multimedia, comfortable social environment, safety and resource saving will be achieved by this technology. 94 refs., 75 figs., 15 tabs.

    The needs for low power LSIs have rapidly increased recently. For the low power LSI development, not only new circuit technologies but also new design automation tools supporting the new technologies are indispensable. The purpose of this project is to develop a new design automation software, which is able to design new digital LSIs with much lower power than that of conventional CMOS LSIs. A new design automation software for very low power LSIs has been developed targeting the pass-transistor logic SPL, a dedicated low power circuit technology. The software includes a logic synthesis function for pass-transistor-based macrocells and a macrocell placement function. Several new algorithms have been developed for the software, e.g. BDD construction. Some of them are designed and implemented for parallel processing in order to reduce the processing time. The logic synthesis function was tested on a set of benchmarks and finally applied to a low power CPU design. The designed 8-bit CPU was fully compatible with Zilog Z-80. The power dissipation of the CPU was compared with that of commercial CMOS Z-80. At most 82% of power of CMOS was reduced by the new CPU. On the other hand, parallel processing speed up was measured on the macrocell placement function. 34 folds speed up was realized. (NEDO)

    This paper illustrates the measurement results of resistivity for specimens including smectite clay minerals artificially synthesized, and also discusses the influence of smectites on resistivity. Three kinds of bentonites, i.e., KN-1, Kawasaki ore, and Kawasaki Sanhaku, were used for preparing smectites. The KN-1 is Na type smectite, the Kawasaki ore is Ca type smectite, and the Kawasaki Sanhaku is acid clay. It is well known that smectites lower the resistivity of rocks. However, the experimental results suggested that the degree of decreasing the resistivity depends on the kind of smectites. The effect of decreasing the resistivity by the KN-1 was much superior to the other smectites. For the KN-1, a thick electrical double layer was formed by Na ions in the interlayers, which resulted in the larger effect of decreasing the resistivity. Swelling capacity and cation exchange capacity (CEC) of the KN-1 were large, which agreed with the above mentioned consideration. Reversely, it was considered that smectites having larger effect of decreasing the resistivity exhibited larger swelling capacity and CEC. 4 refs., 3 figs.

    For people of advanced age in a Japanese style room, the act of standing up is difficult to perform, when they are forced to make use of desks and chairs to hold themselves. In the bathroom and toilet, they often hold on handrails, stool seats, or racks modified to answer the purpose. A device is experimentally manufactured to reduce the burden on the knees when walking on the staircase. Although the device is effective in decreasing the need of muscular activity for knee extension, yet it makes knee bending difficult in some cases thanks to its employment of springs. It is necessary to adjust the sliding mechanism for each person. The difficulty is greater when climbing the stairs. A chronological study is made about changes in everyday behavior due to aging. Chairs are experimentally built, designed to serve as a support during kitchen work. Prototype No. 3 may be put to practical use though its details still want some improvement. To encourage the presence in society of aged people, a portable digital biosignal measuring device is experimentally built, which is to constitute the core of long-term health monitoring systems, and is tested for basic performance. Development has started of a wire-suspended movement assisting system to help aged people move and transfer in conventional type houses. (NEDO)

The available new energy amount may be estimated for solar energy at 10.08 x 10{sup 6} kWh/year, solar heat at 5389 x 10{sup 6} kcal/year, wind power at 20.3 x 10{sup 6} kWh/year, wastes energy at 3111 x 10{sup 6} kcall/year, biomass forestry resources at 77 x 10{sup 6} kcal/year, and biomass stockbreeding resources at 27765 x 10{sup 6} kcal/year. Total energy available will be 30.38 x 10{sup 6} kWh/year for electric power generation, and 36342 x 10{sup 6} kcal/year for heat source. The area has more insolation than the national average, making potential high for solar energy power generation. Areas with annual average wind velocity of 5.5 m/s or higher are distributed widely, whereas wind power can correspond to 90% of the annual electric power consumed in the town. Geothermal temperatures are too low, making it difficult to be utilized for power generation, but could be used for heating hot spring water. Other energies, wastes and biomasses available in the town are not so great in quantity. The township will take the leadership in planning introduction of model type new energy facilities, and develop positively the enlightenment and proliferation activities for the time being. (NEDO)

    An electrically double-layered capacitor is drawing attention as a new power storage technology that can contribute to power load leveling. The issue is to make the capacitor more compact by enhancing energy density. Discussions to improve the energy density are being given on a method by which internal resistance combined with that in electronic circuits may be allowed to some extent. In addition, in order to verify feasibility of its practical use, investigations are made on the optimal operation pattern of the system, possible quantity of introduction, effect of the introduction, and future possibility to reduce the cost. As demonstration of the element technology used in capacitor modules, fiscal 1997 fabricated 35 single cells each with a volume of one liter, and investigated the positioning at practical application, case studies, and operation patterns. Based on the achievements in fiscal 1997, fiscal 1998 performed fabrication and performance test on a capacitor module in which multiple number of cells are connected, and trial fabrication of a next generation type high-energy density capacitor. In addition, as a study on a total system, discussions were given on design and cost estimation of a hybrid type capacitor which combines the capacitor with a NAS battery. (NEDO)

    A study was conducted of a practical applicability of the electric double layer capacitor as a new electric power storage technique. In the study, a comparison was made between the capacitor system and the NAS battery which is most commercialized as one for power storage of all the secondary batteries. The capacitor system is excellent in cycle life, system efficiency, and safety/environment, but in energy density it is approximately a tenth of that of the NAS battery so far. The capacitor system, however, is high in filling rate in modules and enables compact design. As to the 35 fabricated electric double layer capacitor cells, the following tests were carried out: charge and discharge, internal resistance measurement, energy density measurement, characteristics of charge/discharge efficiency, self-discharge characteristics, and characteristics of circumferential temperature.

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

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

    By the ICB method which is one of the ion engineering methods, photomultipliers were formed using organic dye thin films. By changing the energy to bond traps on thin film/metal electrode interface and electric charges by change of acceleration energy of ion beams, a technology was developed for adjusting the optimum operating temperature between -20 degrees C and +100 degrees C. The wide range of operating temperature and favorable SN ratio can be realized. It was made clear that the dark current of the photomultiplier is composed of two components of contribution by the residual charge stored on the interface at photomultiplying and of contribution by charge injection from the Schottky barrier. Based on this, the residual electric charge removal method by heating and applied pulse voltage was developed. The development for practical use was studied of ultra-high sensitive photoelectric converters. As an intelligent photo sensor, a biomimetic visual photosensor was proposed which uses amplification/memory/arithmetic functions and film formation/processability of organic thin films. The paper also described the image sensor. (NEDO)

    Importance was studied of making a research on the chemical process technology using the supercritical fluid. As for its effect on global warming, the amount of CO2 emission was compared during the operation between the conventional process and the process using the supercritical fluid, the CO2 reduction rate and amount were trially calculated, and a CO2 reduction of a several ten thousand ton scale in carbon conversion was predicted. As to hazardous materials and the reaction of waste retrieval, it was made clear that the process using the supercritical fluid was valid also for objects for which the chemical process used to be impossible, which indicates a possibility of the widening field of application. Concerning its effect on the energy conservation, energy reduction of several ten thousand tons in heavy oil conversion was predicted by replacing all the existing processes with supercritical fluids. Relating to the recycling, with the use of supercritical fluids, the process is possible which produces higher quality and yield and fewer unnecessary products such as char than the conventional process. 197 refs., 102 figs., 71 tabs.

    With the purpose of evaluating recoverable hot water quantity and elucidating the change over a long term, investigations were carried out, with the results summarized, on the geology, alteration zone, gravitational analysis, fluid geochemistry and hydraulics in the area. The investigations covered the area of 7 km x 6 km in about 30 km southwest of Sapporo City and were performed for the period from September 10, 1998 to October 31, 1999. The results were as follows. In the Jozankei area, with the Usubetu layer in the Old Tertiary system as the basement, layers are superposed from the Palaeogene Oligocene to the Quaternary Pleistocene. Distributing in various places between Yunosawa vicinity and Jozankei Hot Spring area are acid to neutral geothermal alteration zones. The hot spring gushing-out zone in the Jozankei hot spring area is supposed to be regulated by side-by-side cracks in the NE-SW direction. It was inferred from tritium concentration and a minor component ratio that, as the mechanism of forming a hot spring, water of precipitation origin circulating and residing for a long time on the Usubetsu layer which is marine sediment is heated by a volcanic heat source latent in the depth.

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

    Described herein are research and development of superhigh-sensitivity photocurrent conversion devices. The huge photocurrent multiplication effect exhibited by a thin film of organic pigment semiconductor is expected to be applicable to various new devices, e.g., superhigh-sensitivity, intelligent optical sensor families and photocurrent devices. Photocurrent multiplier thin films of perylene is prepared by an ionized cluster beam method, to evaluate their structures and photocurrent characteristics as the basic knowledge for controlling their characteristics by the ion engineering procedures. Photocurrent multiplier thin films of new, two-layer structure are developed, and improvement and stabilization of their characteristics are studied. Increasing sensing sensitivity by, e.g., introduction of p-n junction and reducing dark current resulting from the light memory effect are found to be effective to improve the S/N ratio. An organic EL light-emitting layer capable of positive/negative feedback, as one of the elementary techniques for realizing intelligent devices, is made on a trial basis and evaluated for its characteristics, and studied for its application to photocurrent multiplier thin films. Functional devices in which the arithmetic and controlling functions of the thin films are utilized are also studied. (NEDO)

    Various kinds of biological fixation processes of CO2 were evaluated from the various viewpoints. Afforestation of tropical and temperate areas, greening of desert, biomass energy production in these areas by energy plantation, coastal mangrove plantation, fertilization with nitrogen and phosphate to outer ocean and coastal, upwelling zone fertilization with iron, and coral reef expansion combined with OTEC (ocean thermal energy conversion) were comparatively investigated as the selected measures. As a result, the cost of CO2 fixation by cultivation of sea weed and plankton was much higher than that of afforestation. The iron fertilization method which was considered to be one of the high CO2 reduction potentials might be economical. However, its effect could not be quantitatively evaluated. The afforestation of tropical and temperate areas seemed to be most feasible in a short term from the viewpoints of economy and environment. It was suggested that the establishment of a systematic water management technology could make greening and afforestation of desert. 76 refs., 27 figs., 28 tabs.

    This paper reports the result of a preliminary circulation test conducted in fiscal 1995 on a deep reservoir (at a depth of about 2200 m) in the Hijiori hot dry rock experimental field. One water injection well and two production wells were drilled to constitute a circulation loop, to which the circulation test was performed to investigate the flow characteristics thereof. The result revealed the following matters: total amount of injected water of 51500 m{sup 3} resulted in a total fluid recovery rate of about 40%; as a result of well stimulation given twice during the initial stage of the water injection, the continuity impedance in the vicinity of the injection well decreased largely (however, the continuity improvement upon the second attempt was considerably inferior to that from the first attempt); and increase in the water injection amount does not necessarily lead to increase in the production amount. The paper describes additionally that it is extremely difficult to interpret non-linearity between the injection and production amounts by using a model prepared previously with a main objective to analyze the Hijiori HDR circulation system. 1 ref., 9 figs., 1 tab.

    This paper reports one example of flow analyses on a circulation test carried out in fiscal 1991 at the Hijiori hot dry rock experimental field (Yamagata Prefecture). A fluid circulation model was proposed to simulate an HDR circulation system for a shallow reservoir (at a depth of about 1800 m) demonstrated in the circulation test by using an electric circuit network (which expresses continuity impedance in resistance and fluid storage in capacitance). Storage capacity of the reservoir was estimated by deriving time constant of the system from data of time-based change in reservoir pressure associated with transition phenomena during the circulation test. The storage capacity was estimated separately by dividing change of storage in the reservoir by change in the reservoir pressure. To derive the storage in the reservoir, a method to calculate non-recovered flows in the circulation test was utilized. The results of evaluating the reservoir capacity in the shallow reservoir using the above two independent methods were found substantially consistent. 3 refs., 6 figs., 1 tab.

    This is a report of overseas dispatch of domestic researchers by the Research Institute of Innovative Technology for the Earth (RITE). When the CO2 reduction effect in the air is evaluated by the chemical fixation of CO2, not only the reduction but also the total reduction of CO2 emission by introducing the countermeasure technology should be investigated. Measures for reduction were evaluated by the LCA technique in Austria, and related information was collected in Europe. The promotion of international cooperation for the CO2 storage in the ocean, and the economy and environmental harmony of the whole system including separation, recovery, transportation of CO2, and its supply into the ocean were investigated in Massachusetts Institute of Technology. Based on the biological synthesis and decomposition of chitin and chitosan (chitin matter circulation) which are components of shell of insects and shellfish, the fixation of CO2 and development of new materials in the hydrosphere were investigated in Norway. To clarify the reaction mechanism and critical factors of the yield of the rhenium carbonyl complex, a CO2 photoreduction catalyst, a relationship between the change of electronic state of complex due to chemical modification and the infrared absorption was analyzed in the United Kingdom. 26 refs., 40 figs., 12 tabs.

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

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

    Survey was made on application technologies of next- generation high-density energy beams. For real application of laser power, application to not exciting source of YAG crystal but machining directly is highly efficient. For generation of semiconductor laser high-power coherent beam, phase synchronization and summing are large technological walls. Short pulse, high intensity and high repeatability are also important. Since ultra-short pulse laser ends before heat transfer to the periphery, it is suitable for precise machining, in particular, ultra-fine machining. To use beam sources as tool for production process, development of transmission, focusing and control technologies, and optical fiber and device is indispensable. Applicable fields are as follows: machining (more than pico seconds), surface modification (modification and functionalization of tribo- materials and biocompatible materials), complex machining, fabrication of quantum functional structured materials (thin film, ultra-fine particle), agriculture, ultra-precise measurement, non-destructive measurement, and coherent chemistry in chemical and environment fields.

    The purpose of this study is to develop an endoscope system for neurosurgery that can provide not only conventional endoscopic images but also ultraviolet-visible spectra, fluorescence spectra, near infrared spectra, and ultra-soundimages of tissue aiming for real-time identification of pathological tissue. The system also incorporates surgical manipulator and devices such as micro forceps and laser surgical instruments for endoscopic image guided surgery. Surgical Manipulator should be a high performance and easy to operate surgical instrument as well as conventional surgical tools such as scissors and knife. Since living tissue deforms during surgical operation, pre-operative three dimensional information for registration of pathological tissue should be modified based on information obtained during surgery. Thus surgical manipulator should be operated under guidance of surgeon's observation. Consequently, surgical manipulator should have various types of imaging and measurement devices such as an endoscope and an ultrasound imaging probe at its end effectors. Based on this concept, a prototype of a new multi channel surgical manipulator system CM cube (CM3, Computer aided Micro Multichannel Manipulator) that has various types of imaging and measurement devices such as ultra-violet-visible camera for spectroscopic measurement, ultra-sound imaging probe, three dimensional endoscope, together with micro surgical instruments and laser surgical systems has been developed. Its performance was evaluated through in vitro/in vivo experiments and clinical application. (NEDO)

    It is intended to develop super devices for medical treatment devices using a three-dimensional micro processing technology by developing and combining precision processing technologies accumulated in the Suwa area. Main targets were placed on device size reduction, and a high reliability portable chemical liquid sustaining injector. This paper describes achievements made in fiscal 1998. Micromotors currently used have as low output torque as 1/4 of the target. Enhancement of reduction gear mechanism efficiency and durability is the problem to be solved. Microtubes with an inner diameter of 0.1 mm were produced on a trial basis by using four kinds of materials. The delivery mechanism assured the targeted flow rate successfully by using the direct cum screw system, but reduction in driving torque is desired. Completion of the cartridge system is also in the realm of aim. Joints will be moved closer to commercialization by selecting materials taking into account the chemical resistance and disposition. Micro connectors and cables still have problems for development. The bubble sensor was virtually decided to be of optical type from the points of detection performance requirements. Detectors and peripheral devices will be reduced in dimensions, and their reliability will be enhanced. The flow rate sensor has a problem to be solved in responsiveness to intermittent flows.

    A material processing technology demanding but low energy and cost and causing low environmental impact was developed using a powder lubricant in a closed metal die system. An inorganic powder excellent in adhesiveness as lubricant was discovered. Powder lubricants for die casting and new carbon lubricants for metal die forging were also developed. In a test in an eco-die casting system, it was found that power was better than water solution in terms of finish and energy efficiency. In the development of a metal forging system using a powder lubricant, existing graphite lubricants and new powder lubricants containing fullerene were subjected to evaluation (ring tests). Two types of graphite solutions now in use and two powder lubricants were evaluated by the ring tests, and this enabled the comprehension of powder lubricant characteristics. For the development of a die casting system requiring no lubricant, a metal die surface treatment method was found that produces a surface excellent in resisting erosion by the application of the aluminizing ion nitriding composite treatment method. In addition, wettability was compared between a PVD (physical vapor deposition)-formed nitride film and the powder lubricant constituents. The report also refers to surveys conducted for commercialization. (NEDO)

    Demands are strong for lower-resistivity transparent conductive films formable at low temperatures (target substrate temperature of 100 degrees C) for the realization of higher-quality electronic equipment required in highly computerized society. The project aims to develop a system for complexation and amalgamation of high-density energy beams (multi-beam thin film formation) and to establish a technology of practical level ultrahigh quality transparent conductive film formation. For this purpose, a load lock system and a laser irradiation system are added to a device developed in the past. A high-quality ITO (indium-tin oxide) thin film is formed at a low temperature by deposition using oxygen cluster irradiation. During film formation using the laser aberration method, ultraviolet rays are applied to the substrate, and a low-resistivity film of 8.9 times 10{sup -5} ohm/cm is obtained on a substrate at 200 degrees C. This process is attributed to crystallization accelerated by ultraviolet rays and to an increase in carrier mobility. In a process of transparent conductive film formation under a complex beam, composed of a laser beam and oxygen cluster ion beam, to be excited for application to mass production, an ITO thin film is formed, with its resistivity extremely low at 10{sup -5} ohm/cm even at 100 degrees C.

    This is No.93 report of National Institute for Research in Inorganic Materials. Single crystal growth of YB66 was investigated to develop the single crystal of YB66 as a spectral material for synchrotron emitted soft X-ray. The emitted light is white light including from visible radiation to hard X-ray. Usually, it is used as homogeneous light through spectra. There are K-absorption edges of Mg and Si in the region ranging from 1 to 2 keV, which is significant for material science. There has been no proper spectral elemental device for application of the emitted spectra. The YB66 is the most suitable for this purpose. For the single crystal growth of high crystalline YB66, high frequency indirect heating floating method has been developed. For the growth furnace, a mechanism has been developed, by which pressurized gas atmosphere can be sealed with magnetic fluid. At the same time, the growth axis can be driven in high accuracy. From evaluation of the elemental device, energy resolution of 0.5{times}10{sup -3} was obtained as expected. By using this spectral device, accurate measurements of XAFS and EXAFS can be conducted with excellent operability for K-absorption edges of Mg and Si. 15 refs., 54 figs., 1 tab.

    Microbes capable of a high biodiesel fuel (BDF) yield from moisture-containing oils assumedly waste oil are investigated. Lipase attributed to Rhizopus oryzae exhibits a high reaction rate of not lower than 90%. The process functions even when microbes are immobilized by BSPs. BDF does not affect driving performance, and black smoke is reduced. A process basic to industrial production is developed by use of a fixed bed reactor. In the production of ethanol from starch thanks to plural kinds of glucoamylase producing yeast, ethanol is produced at a rate of 7-8% under microaerophilic conditions in both proliferation and fermentation periods, which means a success achieved in growing arming yeast equipped with enhanced functions. A 20-liter class bench plant is installed and immobilization by BSPs is tested, when no problem is detected. In a reaction involving these immobilized microbes, a reaction rate near 16% is achieved. In the production of ethanol by yeast immobilized by BSPs, use of a fuzzy control system is studied, and it is found that prolonged stability is available when glucose concentration is sustained at 10-20g/liter.

    This R and D project is aimed at stable production of high-quality, important machine members, which are difficult to sufficiently achieve the required properties by a single material, by carburization while minimizing use of expensive alloy metals, where high-temperature carburizing time is reduced by a plasma-aided system to save energy, and, at the same time, the conventional oil-hardening system is replaced by a He gas cooling/recycling system to solve the environmental problems involved in the former. The exhaust gases released from the plasma-aided system are adequately treated to prevent the problems caused thereby. The conditions of the plasma itself and treated surfaces are sensed in-situ, and the data are fed back to the process controlling system, to keep the treated object stable and high in quality, while minimizing energy consumption. The FY 1998 efforts were directed to studies on methods for sensing the plasma and treated surfaces, and specifications of a mini-plant for the demonstration tests, and to collection of characteristic data for development of some new products to be produced.

    Explosive welding experiments using intermediate materials have been performed on combinations of aluminum alloy with stainless steel, and aluminum alloy with copper that are difficult of explosive welding with an ordinary method. The experiments have investigated interfacial reaction layers and bonding strength. The drive plates have used four kinds of aluminum alloy plates with a thickness of 4 mm and a base material of stainless steel (SUS 304) or copper having a thickness of 9 mm. Investigation has been given on how the interfacial structure and the bonding strength change as a result of using intermediate materials of the similar kind with the base material. The composition in the generated reaction layers has higher aluminum concentration than that has been predicted. This is because more aluminum component has been dissolved because of transformation having converged on the side of the aluminum alloy with smaller transformation resistance. Use of the intermediate materials can reduce energy of collision given on the interface, thus controlling the formation of reactive layers on the interface. This has improved the bonding strength largely, leading to a possibility of fabricating clad materials that have good interface properties. 10 refs., 9 figs., 3 tabs.

    Improvement of the bonding strength of Al/Cu transition joints was tried by single-shot explosive welding technique using a Cu intermediate plate (Cu-IP). As the preliminary experiment, a relatively thin Al alloy plate (4 mm in thickness) and Cu plate (2.5 mm) were bonded by explosive welding to study the effect of bonding conditions on interfacial zone (IZ) structure and bonding strength. As a result, the thickness of IZs increased with an explosive mass involving reduction of bonding strengths, and the use of Cu-IP was effective in reducing the energy applied to IZ because the energy contributed to formation of IZ. As the fabrication experiment of practical Al/Cu transition joints, a pure Al plate and pure Cu plate of 20 mm in thickness and Cu-IPs of 1.0 and 1.5 mm were bonded by explosive welding. As a result, the IZ thickness was 20-70 [mu]m and 5 [mu]m without/with Cu-IP, respectively, and the joint showed the same tensile strength as the base Al plate, suggesting possible production of practical Al/Cu electrical transition joints. 8 refs., 12 figs., 3 tabs.

    This paper presents the behavior of a passively controlled horseshoe vortex at the root of NACA0024 wing which is established on a turbulent boundary layer, A pair of vortex generators of half delta wing is installed upstream of the wing. The flow field of the optimally controlled horseshoe vortex both in case of Common Flow Up (CFUC) and Common Flow Down Configuration (CFDC) is carefully investigated by an X-array hot-wire. In case of CFUC, the horseshoe vortex is not shifted from the wing, because the longitudinal vortex is restrained. The interacted vortex presents a circular profile, in a optimally controlled case. In case of CFDC, the interacted vortex that has strong vorticity by the pairing process is shifted away from the wing. Then, the high momentum fluid flow penetrates between the wing and the vortex.

    Behavior of secondary sealing areas has been measured with two displacement sensors and an underseal pressure sensor, using an overhanging eccentric shaft-type single-rotor research engine equipped with a packaged multichannel slip ring. For the experiment, two-piece nonsplit type and three-piece slanted horizontal split type apex seals were used. The two-piece seal was tilted to the leading and trailing sides of a seal slot during its movement along the rotor housing surface and vibrated on the top end of the leading side of the slot as a fulcrum after the shift from the trailing side to the leading side of the slot. On the other hand, for the three-piece seal, its top part was tilted in all operating conditions, but its bottom part maintained effective area contact with the side of the slot under light load conditions up to medium engine speeds. The working chamber pressure was induced in the underseal in the same manner as the case with the two-piece type. 6 refs., 12 figs., 1 tab.

    In an attempt to elucidate formation and disappearance processes of droplet clusters in spray flames, simultaneous measurements consisting of laser tomography and flame chemiluminescence detection are applied to a premixed-spay burner. The smart combination of measurements provides time-series data-set serving for better understanding of spray flames, which essentially contains inhomogeneity in space and time. It is revealed that referential flame propagation through a premixed-spray stream plays a significant role in creating droplet clusters and that droplet clusters formed in this manner evanesces from their outer boundaries. Those observation confirms that the premixed-spray flame comprises both premixed-mode flame in upstream region and diffusion-mode flame in downstream region, respectively, i.e, two-stage flame structure previously reported for spray flames stabilized in either counter or stagnation flows.

    Like the stainless steel and the stainless steel belt used in the rolling stock, materials treated by process and weld has a high strength and a good ductility, moreover, was expected that weld softening would not occurred. In this study, formation of the ultra-fine crystal grains based on the M to [gamma] reversion transformation of low C, Cr-Ni martensitic stainless steel and effect of Si on change of mechanical properties were investigated. A high-strength stainless steel with a good ductility and without weld softening was developed. Main results obtained are as follows: After a steel was cold-rolled, the reversion treatment at the region between As and Af temperatures (600 to 640[degree]C) was carried out, a duplex structure with diameter of the ultra-fine grains of about 0.5 micron meter that is composed of [gamma] phase concentrated Ni and sintered M phase was formatted, and excellent mechanical properties with a high strength and a good ductility could be obtained, diameter of reversion [gamma] grains was dependent on reversion temperature. Diameter of [gamma] grains became large, and more homogeneous and uniform at higher reversion temperature. 20 refs., 11 figs., 2 tabs.

    For the construction of a solidified coal ash roadbed, desulfurized gypsum and a small amount of slaked lime are added to coal ash that is the main material, moisture is adjusted, the resultant moist powder is mixed in a screw-type mixer and transported aboard a dump truck to the construction site, and then solidified by rollers. The material is easy to install, and the roadbed is high in serviceability. With no serious damage occurring in the paved surface for nine months after the placement, the road keeps on functioning satisfactorily as a provisional road for use in the execution of the construction work. Foamed asphalt is prepared by adding water to asphalt in the liquid state at high temperature for the formation of fine foam for a 10-15 times expansion of the asphalt volume. Such asphalt is lower in surface tension and enhanced in adhesiveness to other materials, and mixes completely with the road materials at normal temperature for the construction of a reinforced roadbed. The foamed asphalt covers only fine aggregate but not coarse aggregate, and the latter is tightly solidified by bitumen etc. by tamping for the realization of a strong structure. Foamed asphalt is a material that works effectively when used for a road where dynamic load is dominant. 8 refs., 18 figs., 7 tabs.

    This report covers a sand compaction pile (SCP) process performed for the improvement of the sea bottom along the west-side revetment of the power station where a 10-odd meter thick sedimentary layer of soft clayey soil exists. Since the sea is only 5m deep in this area, an engineering method is chosen capable of minimizing the swelling of the ground, and changes in the physical properties of the composite ground that may affect the stability of the revetment are investigated. In this report, an estimating equation is proposed for accurately predicting the swelling, including the additional swelling of the ground already swollen, to result from the SCP-assisted improvement of the ground and a description is given of changes in composite ground mechanical properties induced by the SCP-assisted engineering work. A `one-directional construction system with one block constituted of three spans` is contrived. Furthermore, an estimating technique taking into account the secondary swelling is proposed. As the result, the apparent swelling rate agrees very well with the actual swelling rate. An SCP method with its capability enhanced may be established by considering time-dependent changes in the mechanical properties of the clayey soil between piles and their impact on the safety factor. 4 refs., 13 figs., 3 tabs.

    The effect of surface oxide layer on the titanium before bonding on the bonding strength of titanium clad steel by hot roll bonding was investigated from a view point of microstructure of the bonding interface. The bonding test of iron and titanium by hot roll bonding at 850{degree}C was conducted under the various surface conditions of titanium plate such as as-relieved, oxidized or machined. The mechanical properties of clad steel was evaluated in terms of tensile test in the rectangular direction to the bonding interface and observation of micro structures of bonding layer. As results, the bonding strength deteriorated remarkably in the clad steel produced using the titanium having oxide layer on the surface comparing with that using the machined surface of titanium. In the clad steel produced using the titanium with surface oxide, uncontinuous intermetallic compound was observed at the interface of {beta}-Ti and Fe, while in the clad steel produced by the titanium without surface oxide, no remarkable intermetallic compound was observed. Oxide layer on the titanium surface promotes the formation of inter metallic compound of titanium and iron at the bonding interface and deterioration of bonding strength. Such oxide layer, however, was found to be not an obstacle to the accomplishment of metallurgical bonding. 6 refs., 13 figs.

    A policy of improving a very large floating body was planned based on its dynamic characteristics, and a proposal was made thereon. Furthermore, discussions were given on stability that considers effect of elastic deformation required when a structure is mounted on a floating body. With respect to a structural design of a very large floating body in which elastic response is governing, and upon modeling the very large floating body into an aeolotropic plate on an elastic supporting floor, it was shown that the existing range of natural vibration speed in the elastic response is in higher range than the natural vibration speed of heave. It was also indicated that the peak height of response to waves in resonance is inversely proportional to wave frequency, and furthermore, degree of flowing in of vibration energy during the resonance is determined by an inner product of spatial vibration patterns of wave force and the excited mode shape. A proposal was made on a floating body improved of excessive response in the floating body edges by changing the characteristics of the floating body edges. In addition, discussions were given on stability that considers elastic deformation of a floating body that becomes necessary when a structure, such as a building, is built on a very large floating body. 9 refs., 9 figs., 3 tabs.

    There has been tried to apply unified assessment method using hot spot stress, which is effective to evaluate fatigue strength of fillet welded structures for ships and marine structures. This method can be applied to complicated structures and is independent of welding processes. In this study, first, stress analysis has been conducted for two-dimensional fillet welded joint models with various combinations of plate thickness and weld leg length of general fillet structures by means of boundary element method. Then, critical position, which is not affected by local stress concentration due to bead, was determined from the detailed stress distribution in the vicinity of weld toe. As a result, a general equation has been proposed to estimate the hot spot stress by one-point representative method. Second, the fatigue tests of typical fillet welded joints have been conducted by applying this method. Consequently, it was demonstrated that the unified fatigue strength can be evaluated by the S-N data based on hot spot stress range determined from the proposed equation, independent of structural stress concentration. 22 refs., 14 figs.

    Poly(L-lysine-alt-terephthalic acid) microcapsules change their particle size, volume and the membrane permeability, depending on pH and the ionic strength. The mechanisms of the change in membrane shape were studied. The water content in the membrane and the sensitivity to the stimuli changed corresponding to the changes in the charge density and in the hydrophobicity of the membrane. These phenomena were considered as the phase transition of a hydrogen. In aqueous solutions, the microcapsules shrank by the addition of multi-valent cations or by the addition of the solvent with low permittivity such as ethanol. The viscosity of the membrane was high when the water content of the microcapsules was high. Also, the mass density of the membrane was inversely proportional to the microcapsule size. 4 refs., 3 figs.

    Transmission electron microscopic observation and a joint strength test were carried out on diffusion-bonded interface of Al-Mg-Si series 6063 alloy to investigate behavior of the surface oxide film and its effect on the bonding strength. The test pieces are made of the Al-Mg-Si series 6063 alloy and industrial pure aluminum 1080 cut out from a rod as a reference material. The bonded surface was applied with electrolytic grinding or wire brush finish. Analysis of electron diffraction diagram revealed formation of Al2MgO4 on the bonded interface of the 6063 alloy in either case of the electrolytic grinding or the wire brush finish. However, it was not possible to derive the electron diffraction diagram from oxide film on the bonded interface of pure aluminum, and the oxide film was thought amorphous. Tensile strength of the diffusion-bonded joint of the 6063 alloy approached the strength of the base material at considerably lower bonding temperature and with smaller bonding deformation than in pure aluminum in either case of the bonded surface electrolytically ground or wire-brush finished. This was thought to have been caused from difference in behavior of the oxide film. 16 refs., 12 figs., 3 tabs.

    The effect that the set data of the load control system in a wind power generation system exerts on the dynamic behavior of a system was investigated. The wind power generation system consists of a hybrid wind turbine with combined Darrieus and Savonius rotors, load with a generator and battery in the center, and a controller. A constant-tip-speed ratio operation that holds the circumferential speed ratio in which the power coefficient is maximized irrespective of the change in wind velocity was used to extract and convert the wind energy more effectively. In a high-wind velocity area, the system is operated at a fixed speed, and the increase in rotation is suppressed to protect the wing strength. In a large system, the response characteristics are only slightly improved by the limited load operation range and influenced rotor inertial. Power cannot be fully extracted even if the control system is changed in setting, and the applicability to the wind situation remains low. During the actual operation, the adjustment value of the control system should be set so that the output operation is satisfactorily possible in the specified load operation range, that is, the change in the instantaneous value of an effective power coefficient indicates almost flat gain characteristics in frequency characteristics. 14 refs., 10 figs., 2 tabs.

    The April 11, 2011 Fukushima-ken Hamadori Earthquake (hereafter the 4.11 earthquake) formed co-seismic surface ruptures trending in the NNW-SSE direction in Iwaki City, Fukushima Prefecture, which were newly named as the Shionohira Fault by Ishiyama et al. (2011). This earthquake was characterized by a westward dipping normal slip faulting, with a maximum displacement of about 2 m (e.g., Kurosawa et al., 2012). To the south of the area, the same trending lineaments were recognized to exist even though no surface ruptures occurred by the earthquake. In an attempt to elucidate the differences of active and non-active segments of the fault, this report discusses the results of observation of fault outcrops along the Shionohira Fault as well as the Coulomb stress calculations. Only a few outcrops have basement rocks of both the hanging-wall and foot-wall of the fault plane. Three of these outcrops (Kyodo-gawa, Shionohira and Betto) were selected for investigation. In addition, a fault outcrop (Nameishi-minami) located about 300 m south of the southern tip of the surface ruptures was investigated. The authors carried out observations of outcrops, polished slabs and thin sections, and performed X-ray diffraction (XRD) to fault materials. As a result, the fault zones originating from schists were investigated at Kyodo-gawa and Betto. A thick fault gouge was cut by a fault plane of the 4.11 earthquake in each outcrop. The fault materials originating from schists were fault bounded with (possibly Neogene) weakly deformed sandstone at Shionohira. A thin fault gouge was found along the fault plane of 4.11 earthquake. A small-scale fault zone with thin fault gouge was observed in Nameishi-minami. According to XRD analysis, smectite was detected in the gouges from Kyodo-gawa, Shionohira and Betto, while not in the gouge from Nameishi-minami.

    This survey in Europe surveyed the current status of the coal industry, supporting directions and policies of governments on the coal industry, and summarized the information thereof. The survey included movements in policies and activities in transfer of technologies to overseas countries by governments and corporations of different countries, and the current status of the coal technology training project. The survey covered Britain and Germany. The British coal industry is facing a serious difficulty because the electric power industry being the major coal purchaser has changes its sourcing to natural gas. In addition, the open-cut mining which has been considered high in productivity has no further hope of big progress due to regulations in the environmental aspects. However, as a result of having performed positively research and development on production cost reduction, the production efficiency has grown excellently. Using this situation as the base, positive advancement into overseas countries is being carried out. The German coal industry has, in spite of having reduced the production size and the number of coal mines, shifted coal purchasers to electric power generation and steel making areas, and its quality and supply capability stand equivalent to those of imported coals.

In the U.S., a report was taken up from Executive Office of the President which is entitled `the federal government R and D of energy for solution to problems in the 21st century.` The report made analyses of the federal government R and D of energy and at the same time recommended an increase in R and D budget and reinforcement of the organization of the Department of Energy. In Europe, the carbon tax, CO2 tax, energy tax, etc. are introduced or studied for reduction of CO2 emissions. OECD made public a report approved in May 1997 which is entitled `the environmental tax and green tax reform.` Also studied were the introduction and effects of the carbon tax aiming at reducing CO2 emissions in developing countries. More attention is being paid to economic effects predicted in case developed countries reinforce various kinds of measures for targeted reduction of greenhouse gases. 2 figs., 4 tabs.

    Introduction of a number of robots and consumption of a large amount of energy are unavoidable if a complicated process operation is to be carried out by robots in an extensive work site. Great energy conservation is contrived by developing robots applicable to manufacturing in performing a variety of operations in place of human beings and thereby reducing the number of robots to work. This paper explains the fiscal 2000 results. For dual-handed cooperative tasks, a function was examined capable of gripping an object without giving a humanoid robot an instruction of an exact gripping position. A method was designed to prepare a command for the other arm through a command for one arm, with torque impedance control employed for the purpose of avoiding damage due to collision. A study was conducted on a three-dimensional shape detecting model using a visual device of a robot. In grasping problems of balance control of a humanoid robot, the behavior of a robot consisting of multi-links was considered as behavior of inverted pendulum, with possibility checked for the stabilization of the balance. For the purpose of putting the virtual robot platform previously developed to practical use, a three-dimensional operation tool of run-time user interface was developed, with research conducted on the sophistication of robot application.

Carrying out the development smoothly and efficiently requires accumulation of the operational know-how in both of the periodical check and maintenance and the aspects of hard and software to maintain the functions and performances of the robot platform having been developed in the previous fiscal year. Checks were given on fitting of the fasteners and connectors, batteries, and sensors. Operations were confirmed and adjusted on the liquid crystal projector of the surrounded visual display system for remotely controlled operation, polarization filters, screens, reflector mirrors, and wide viewing angle cameras. Verifications were made on fitting of the arm operation force sensing and presenting system, checks on the mechanical components, and operation of the driving system, whereas no change has been found in the operation for the period of one year, and sufficient performance was identified for the remote robot operation. The virtual robot platform has presented no crash and impediments during erroneous use in the disks of the dynamics simulator and the distributed network processing system. (NEDO)

    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.

    Field tests have been performed on the next generation phosphoric acid fuel cell power generation systems to collect and analyze the long-term operation data and trouble cases by introducing the final proliferation pattern into the actual demand on a trial basis. This paper reports the achievements in fiscal 2000. The locations of executing the field tests in fiscal 2000 are the 15 sites, including the NTT Central Training Center, and the Environment and Energy Exploratirium. Measurements were carried out at each test site on fuel gas consumption, fuel cell output power amount, utilized quantity of heat at low temperatures, utilized quantity of heat at elevated temperatures, and discarded quantity of heat. In addition, the total demand power amount and the shutdown information were also put into order. As a result of the evaluation analysis, the second factory of Senhoku Manufactory recorded the longest operation time of 23,777 hours, whose operation factor has reached 92%. Five systems had the continuous operation time exceeded 5,000 hours. The power generation efficiency was about 40% in a system using the town gas 13A fuel, wherein the total efficiency was 90% or greater. The largest number of failures in fiscal 2000 was seven at Tochigi Factory of Kirin Brewery, whose average number of failure was 1.6 a year. (NEDO)

    With an objective to make clear the basic information about aged and handicapped persons requiring welfare goods upon the development thereof, this survey performed a questionnaire survey to business entities performing design, development, improvement and fitting of welfare goods. The questionnaire survey selected 879 business entities involved in manufacture and sale of the welfare goods. The effective reply recovery rate was 19.3%. The questions had the data contents required by products classified into body dimensions, motion capability, sensory functions, and work capability, asking to state data contents required for each item, reasons for the needs, and data sources. The data source currently utilized reveals that most of the replied enterprises utilize data derived from the company's own measurements, developments and experiences.

    A comprehensive analysis was conducted into the results of a survey on the state of existence of geothermal energy resources in the Musadake region, Shibetsu-gun, Hokkaido. The region was volcanically active in the period from the Neogene period into the quaternary, with some volcanos still active even today. The geological structure on the whole is characterized by the Musadake/Mt. Shitabanupuri fault which is the major structure running NNE-SSW and having a folding structure. It is inferred that Musadake is the heat source responsible for the underground temperature distribution in this region. The maximum temperature of 274 degrees C is recorded at borehole N11-MD-3 in the northeastern part of Musadake, and the temperature falls rapidly as the distance from the borehole increases. Ejection of geothermal fluids is observed at boreholes N11-MD-3 and N11-MD-4. It is inferred that the deep-seated geothermal water is of the neutral Cl type with Cl concentration estimated at approximately 12,000 mg/liter. Steam composition is characterized by a gas concentration level that is as high as 3-4 vol.%. The gas is composedly mainly of CO2 and contains some hydrocarbons. Fluids in this region are classified into water mixing into deep-seated geothermal water and groundwater originating in meteoric water. (NEDO)

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

    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)

    This paper introduces a variable speed wind power turbine developed jointly by EPRI and US Wind Power Corporation. This wind power turbine has a wind velocity responsive construction in which generated alternating current power has the frequency vary with change in the shaft rotation speed. The specified performance calls for a cut-in of 4 m/s and cut-out of 29 m/s, wind velocity variable. The blades are made of laminated fiberglass, and the rotor has a diameter of 33 m, rotation variable. The tower height is classified to 24 m, 30 m, and 42 m. The blade pitch is controlled by a linear hydraulic cylinder, and the turbine is controlled by a microprocessor. The wind turbine has a system interconnecting control and data collecting system. Two induction three-phase generators are used. EPRI has calculated its power generation cost at 5 cents/kWh if wind blows at an annual average velocity of 16 miles per hour. This is nearly equivalent to the cost at new power plants. US Wind Power Corporation has disassembled 22 experimental models that have been in operation to investigate wear in the machines. Its economy is evaluated comparable with that for fossil fuel technologies. 1 fig.

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

    In this project, we manipulate interaction between photons and electrons in semiconductor nanostructures to study fundamental understanding of electron-photon interaction in ultra-small space and Ultrafast time domain. In addition, on the basis of these results, we explore the optoelectronics nanostructure devices of the next generation. In this research project, we developed new techniques for fabricating quantum dot structures. First, quantum dots of 10nm were grown in two-dimensional V-grooved structures which were formed on SiO{sub 2} patterned substrates by MOCVD. In the same V-grooves, vertical quantum wires were also formed. As the second new technique, we developed self-assembling growth technique for the quantum dots utilizing Spinodal phase separation. In order to investigate the quantum dots using nano-scale characterization technique, we developed low-temperature scanning near-filed optical microscope. Luminescence from as single quantum dot and a single quantum wire were obtained. In addition, luminescence from a single quantum dot through tunneling current excitation by STM was also successfully obtained. Furthermore, micro-photoluminescence measurement achieved time and spatially resolved photoluminescence from a single quantum dot. This micro-photoluminescence also revealed electron dynamics in mesoscopic structures and point contact structures through carrier drag effect. Finally we have succeeded in fabricating vertical microcavity quantum dot lasers by MOCVD and obtained picosecond pulses form the devices. (NEDO)

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

    This paper describes cooperative development of bio-treatment technology for mine waste water generated by operating mines in China. Certain types of bacteria have capability to oxidize ferrous iron in the waste water into ferric iron ions. The bacteria cause ferric iron oxides in low pH regions to get deposited, and can remove them from sedimentation by using cheap calcium carbonate as a neutralizer. Volumetric reduction in waste sediments may also be achieved during removing heavy metals in a pretreatment process. Great advance may be expected in taking actions to prevent water quality contamination. This paper summarizes activities taken in fiscal 1998. Eight site surveys in total were carried out using 47 persons in total. Major activities included operation study guidance of a pilot plant, and surveys for measures on heavy metal generation sources in Wushan Mine. In addition, site surveys were performed at Dexing Mine and Yinshan Zinc Mine. Subsequently from fiscal 1997, a bench scale testing equipment used in Japan and consumables were transported to China. The operation study data on the pilot plant were put into order and analyzed. Concept design was also made on a waste water treatment facility for Wushan Mine. (NEDO)

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

    A solar heat-aided system is investigated, in which CO2 is recycled, with methanol, dimethyl ether, etc., serving as carriers of the solar heat energy. In the evaluation of validity of the system as a whole, the system scale and economy and technologies necessary for the system were studied, which was to find out whether solar methanol production was commercially feasible in the sun belt. It was concluded that solar methanol was capable of competing against LNG (liquefied natural gas) in cost, that Japan was able to establish its own technologies for developing coal gasification solar reactors using overseas technologies for information, and that therefore such a system was technologically and economically valid. In the study of related technologies as is, surveys were conducted on coal gasification, natural gas reforming furnaces, methanol synthesis, dimethyl ether synthesis, light condensing technology, current state and cost of solar reactors, etc. Also investigated were the marketability of solar hybrid fuel, CO2 reduction efficiency, and the construction cost at the assumed site of construction (Australia).

    At the third Conference of the Parties to the United Nations Framework Convention for Climate Change (COP3) held in December 1997, the industrialized nations have agreed on development and proliferation of innovative technologies under international cooperation and transfer of environmental technologies to developing countries by expanding and strengthening CTI being the framework to be progressed spontaneously. Under the international strategic research project for global environment, NEDO has been promoting positively the research and development, whose support is urged to be expanded further in the future upon receiving the present agreement. Therefore, NEDO has performed the present survey in order to propose frameworks and measures for strengthening and expanding CTI. From among the policies and measures to be taken by the related countries based on the COP3 protocol, fiscal 1997 has performed review and new establishment of plans involved with execution of the items related to technology development, and surveys on action movements such as review and expansion of the measures, as the first stage. Fiscal 1998 has executed surveys focusing on the network for technology proliferation and transfer to developing countries as the second stage. (NEDO)

    Intermetallic compounds, although attracting much attention as most promising materials serviceable at superhigh temperature, are very fragile at normal temperature, which is one of their major disadvantages. Structures of these compounds prepared by the melting method are controlled to improve their toughness by, e.g., changing phase ratio of the initial crystal for the Mo-Si-Nb system to prevent cracking during the melting and casting stages, addition of a third element (e.g., Zr, Ti or Hf) or a mixed component of Nb and Zr to control the structure of Mo{sub 5}Si{sub 3} considered to be a cause for the cracking, and controlling melting and solidification rates for the FZ melting method. The three-phase microstructures with added Hf or Zr show improved toughness, but need additional procedures for controlling solidification and cooling conditions. For the powder method, the MA conditions are investigated with a two-element system, and the effects of Al or Zr as the third element added to the base composition on the composite microstructures and constituent phases are also investigated. Unlike the melting method, the powder method causes no cracking problems during the stock preparation stage and hence is expected to be applicable to production of larger stocks. However, the products by this method are found to be insufficient both in toughness and high-temperature strength. It is necessary to develop methods for cutting down and controlling oxides in the grain boundaries, in order to prevent deterioration of their strength at high temperature. (NEDO)

    Trends were surveyed for development of an ultra low loss power element. Performance improvement has been progressed on power semiconductor elements by using Si as the raw material, but loss reduction has come close to the physical limit. SiC is expected of possibility to go beyond this limit. SiC is so very excellent that its band gap is two to three times greater, insulation breakdown electric field is 7.5 times higher, temperature to become a true semiconductor is three to four times higher than those of Si. The wide gap can reduce high temperature leaking current in p-n junctions, and the increased authenticity temperature can increase the upper limit for operation temperature. The insulation breakdown strength being higher by one digit can reduce the drift layer thickness, and is expected to dramatically reduce the loss. The problem is that high quality crystals have not been obtained to date. One of the promising application fields is electric vehicle. The device currently using the power element in the largest scale is used in frequency converting stations to link the 50-Hz power network in the eastern part of Japan to the 60-Hz network in the western part of Japan. Surveys were carried out on the Sakuma frequency converting station and the New Shinano substation. (NEDO)

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

    Polymer electrolytes are essential materials to develop safe and reliable rechargeable lithium batteries. Nobel 'property-gradient' polymer electrolytes in which ionic conductivity distributes along with their thickness were synthesized by employing plasma polymerization technology. Vinyl monomers bound with oligo-ether side chains via siloxane bond were served as starting monomers for plasma polymerization. Ionic conductivity of formed polymers changed along with their thickness. Monomer solutions containing lithium salt which were impregnated into porous matrix were polymerized by exposing RF plasma and directly gave polymer electrolytes. The polymer electrolytes showed distributing ionic conductivity through its direction of thickness; 'property-gradient' polymer electrolyte were prepared. Metallic lithium surface were covered with thin plasma polymer layer containing fluorine to suppress dendritic lithium deposition during charging. The layer reacted so fast that suppression of the dendritic deposition was not satisfactory. (NEDO)

    Experiments and studies are conducted for reducing along-the-road automobile running noise. In the study of noise generation due to tire vibration, it is found that the main mechanism of noise generation on a well-drained pavement is the vibration of tires. A calculation model is built for estimating the vibration of the tire belt from the characteristics of the road surface and the tire. In the study of air column resonance in the tread groove, a method is studied of measuring fluctuations in the sound pressure in the tread groove. Measurement is conducted, and it is found that the generally accepted explanation, in which air column resonance is attributed to tread vibration generated upon collision of the tire with the road surface, needs further study for substantiation. In a model experiment, it is found that air column resonance hardly occurs on a well-drained pavement. In the study of hydroplaning, it is found that, even when the total volume of the tread longitudinal grooves is the same, the hydroplaning performance tends to improve when the groove arrangement and crown curvature are proper.

    This research was made for investigating the impact of geothermal development on hot spring, ground water level and spring water by drilling 3 investigation wells N9-AY-3, N9- AY-4 and N9-AY-5 in Akinomiya district. Some research items for hot spring showed slight fluctuation until 1997, however, those showed no fluctuation due to drilling of the 3 investigation wells in fiscal 1998. These results suggest that drilling of the investigation wells has no effect on the spring and quality of hot water in Akinomiya district. Drilling of N9-AY-4 well is carrying out continuously after Sept. 1998. Fluctuation of ground water levels was dependent on precipitations, however, drilling of the 3 investigation wells has no effect on the ground water level. These results suggest that drilling of the investigation wells has no effect on the spring of hot water in Akinomiya district. Every research item for spring water showed relatively slight fluctuation stably. These results suggest that drilling of the investigation wells has no effect on spring water in Akinomiya district.

    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.

    This project is aimed at promotion of effective utilization of unutilized resources by transforming histidine-containing peptide (anserine), enzymatically hydrolyzed muscle protein present in lean salmon swimming off the Sanriku District in the spawning season, into functional peptide. A reactor system, comprising an enzyme-immobilized column and rotary bioreactor, is investigated to efficiently produce peptide by enzymatically hydrolyzing the water-insoluble muscle protein. Anserine is isolated by ethanol extraction, ion-exchanging and partition chromatography. The TPTZ and ABTS methods are developed for speeding up measurement of the antioxidant activity. The salmon muscle protein is hydrolyzed by 3 types of enzymes, to measure the free radical erasing activity by the ABTS method. The enzymatically hydrolyzed protein is fractionated by gel permeation chromatography. The fractions having a molecular weight of 10,000 or less show strong antioxidant activity. The hydrolyzed protein shows improved activity by the iron rhodanide method when it has histidine at the center of tripeptide, and strong radical erasing function when it has thyrosine or tryptophan at the carboxyl terminal.

    Study was made on popularization of the proper treatment technology of industrial wastes in Asian regions. In principle, industrial wastes should be recycled in a country concerned, however, because of a difference in technology and industrial location, treatment of all industrial wastes in a country concerned is impossible. International cooperation is thus indispensable to promote proper efficient practical measures for environment. For studying the possibility of the international cooperation between Japan and Asian countries concerned for further recognition and solution of industrial waste problems, 'International Symposium on the Asian Industrial Waste Issue' have been held in Tokyo since 1997 for governmental staffs. In fiscal 1998, Malaysia was invited in addition to China, Philippines and Thailand for popularization of the proper treatment and recycling of industrial wastes in Asian regions. In every Asian countries, poor collection of discharge, treatment and disposal data is an obstacle to effective treatment. Technical cooperation and financial support by developed countries are demanded. (NEDO)

    Until now, the prescription of communication devices for disabled people has been dependent on the experience of technical experts who are working for them. To improve this situation, the aim of present study is to develop the objective methods for evaluating satisfaction of communication devices. Further aim of this study is to get the basic data for using electroencephalogram for thinking switch of communication devices. 1) Under imaging real communication devices, the menu of two experimental subjects were designed with three tasks which have different difficulty. Five physiological indexes (heart rate, coefficient of variation of R-R intervals, respiration rate, skin temperature and plethysmograph), which are known to closely correlated with mental stress, were studied during three different tasks in each experimental subject. In addition, psychological test were also performed before and after each tasks. In the first subject a significant difference was detected only in psychological test among three tasks. This result may come from the small difference of difficulty in each tasks of the first subject. In the second subject, significant differences were observed in the coefficient of variation of R-R intervals, the respiration rate and psychological test. Other physiological indexces, skin temperature, heart rate and plethysmograph, may be useful. However, the reconsideration will be needed to find the usefulness of these indexes for evaluating mental stress. 2) Biofeedback control of mu rhysm, an electrical brain wave, was investigated for the possibility of thinking switch in three graduate students. In one of three students, changes of amplitude were observed bilaterally although we had expected the unilateral change. Further studies will be needed to clarify the best method of biofeedback experiment. (NEDO)

    The research is conducted in cooperation with Industrial Technology Development Institute of the Philippines, and aims to solve water related problems such as unstable water supply and water quality pollution though developing a waste water treatment and recycling system which is easy to operate and maintain, low in cost, and usable in the Philippines. Fiscal 1998 is the second year of the project. Statistics are studied about the load that each industrial branch imposes on water for its pollution, and it is found that food manufacturers, paper pulp mills, and fiber dyeing plants are heavily responsible for water pollution. A method consisting of single-tower UASB anaerobic treatment and activated sludge treatment is applied as a water treatment process to Ram Food Products Corporation, and its optimization is studied. A removal rate 60% is achieved after a 12-hour treatment period at a COD (chemical oxygen demand) rate of 8g/liter/day. A method consisting of coagulating sedimentation and activated sludge treatment is applied to the waste water from a Solid Mill Corporation dyeing plant, when it is found that the water after ultimate treatment is almost colorless and that COD is 76mg/liter and BOD (biological oxygen demand) 13mg/liter, and these suggest that the waste water is recyclable. Since it is low in COD removing rate, the application of anaerobic treatment to high-concentration water after washing is not appropriate. (NEDO)

    For a ceramic gas turbine to achieve efficiency of 42%, materials capable of withstanding approximately 1300 degrees C are required. In fiscal 1998, the mechanism of creep deformation and life prediction are studied, with specimens exposed to a short-term high-stress conditions equivalent to a time to fracture of 1000h. It is known after studies in the past that, under a stress of approximately 240Mpa, the logarithmic values of the load stress and time to fracture may be described by two differently inclined straight lines. Strain is accurately measured by use of a CCD camera for the determination of a creep curve, and then stress indexes are worked out. It is then found that the stress indexes are 4 on the lower stress side of 260MPa and 11 on the higher stress side of the same. This enables the extrapolation of short-term creep fracture data for the prediction of long-term life. No large-scale reduction in resistance to creep due to changes in the crystal phase is not predicted. Longitudinal sound wave speeds are measured, and the result manifestly describes how the longitudinal sound wave speed slows down with the progress of creepage in the material. Reference is also made to international reports about the study of ceramics performance tests and evaluation methods, international joint studies about mechanical properties tests, and the international round robin test of material powder.

    The paper reported the result of exploratory drilling works done in the Sarugadake area as a part of the survey of the fiscal 1994 NEDO geothermal development promotion. The area is a mountainous area located approximately 10km southwest of the Aizu basin and is consisted of ridges 700-900m above sea level (the highest is 907m at Sarukuradake) and sharp slopes which are the lower part of the ridges. The area adjacent to the north has a flat topography 400-500m above sea level with the Nishiyama hot spa as a center, and the Yanaizu Nishiyama geothermal power plant is there. Around 295-345m below sea level, there is a clayey zone which is seemingly a fault. There are sections where there are lots of cracks around between 1200m and 1600m below sea level. However, lost circulation was seen only at 419m below the sea. The distribution of earth temperature is a typical thermal conducting type in which the temperature linearly increases toward the deep area, and the highest temperature was 194{degree}C at a depth of 1800m. The average temperature gradient was 1.03{degree}C/10m, and there are generally seen few changes. Abnormality of the self potential corresponded to boundaries of fracture zones or geological layers/rock facies, and resistivity changes. The distribution of resistivity was also shown. As a result of the water injection test, water permeability of this mine was unfavorable. 4 refs., 26 figs., 38 tabs.

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

    Described herein are the FY 1988 results of development of corrosion-resistant ceramic materials for garbage incinerators. Residue released when porcelain stocks are collected is selected as the inexpensive stock for SiO{sub 2}-Al{sub 2}O{sub 3}-based refractory materials. It is incorporated with carbon black and reduced at 1,200 to 1,500 degrees C in a nitrogen atmosphere. Synthesis of the target Si-Al-C-N-O-based compound succeeds in the presence of a solid catalyst, but it is a fine powder, and hence that of the massive compound fails. The commercial ceramic materials and new refractory materials, made on a trial basis, are evaluated for their resistance to corrosion using fry ashes collected from a commercial incinerator. These ashes are higher in melting point, more viscous, holding a larger quantity of attached slag and more corrosive than synthetic ashes. These materials are corroded acceleratedly as temperature increases to 1,200 degrees C or higher, more noted with the ceramic materials than with the refractory materials. Oxidation and melting characteristics of the molten slag affect corrosion of some materials. Use of the graphite-based material shall be limited to a section below the slag surface, where graphite is oxidized to a smaller extent. The MgO-based material is promising. The Al{sub 2}O{sub 3}-Cr{sub 2}O{sub 3}-based material is more promising than any other material developed in this study. Their bending strength before and after the corrosion test is measured at normal temperature to 1,700 degrees C, to investigate their deterioration by high temperature and corrosion. (NEDO)

    With an objective to serve for environmental preservation in developing countries, joint researches have been performed on anaerobic waste water treatment systems utilizing bio-technology. This paper summarizes the achievements in fiscal 1995. In the research cooperation with Thailand, a bench scale testing equipment was used to verify activity of granules, and granulation tests were performed. In the operation research by using a pilot plant, abrupt variation in quality of the feed waste water was encountered, whereas both of the fixed bed system and the UASB system have not reached the stage of tests at the targeted load. In the research cooperation with Indonesia, the actual waste water test in the laboratory scale verified that Tofu manufacturing waste water may be easily decomposed anaerobically, and the kitchen waste water aerobically. The bench scale test is in continuation on actual waste waters by experimenting the applicability of the fixed bed and UASB reactors. In the research cooperation with Malaysia, analysis was performed on chemical factory waste water properties, and so was the anaerobic treatment characteristics test in the laboratory scale. In addition, a preliminary experiment using the bench scale testing device was begun. (NEDO)

    The purpose of this study is to develop a high-rate and clean chemical vapor deposition (CVD) process as a breakthrough technique to overcome the problems that particles generated in the gas phase during CVD process for preparation of functional thin films cause reduced product yield and deterioration of the films. In the CVD process proposed here, reactant gas and generated particles are electrically charged to control the motion of them with an electric field. In this study, gas-phase nucleation phenomena are evaluated both theoretically and experimentally. A high-rate, ionized CVD method is first developed, in which reactant gas and generated particles are charged with negative ions generated from a radioisotope source and the UV/photoelectron method, and the motion of the charged gas and particles is controlled with an electric field. Charging and transport processes of fine particles are then investigated experimentally and theoretically to develop a clean CVD method in which generated particles are removed with the electric forces. As a result, quantitative evaluation of the charging and transport process was made possible. We also developed devices for measuring the size distribution and concentration of fine particles in low pressure gas such as those found in plasma CVD processes. In addition, numerical simulation and experiments in this study for a TEOS/O{sub 3} CVD process to prepare thin films could determine reaction rates which have not been known so far and give information on selecting good operation conditions for the process.

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

    This advance survey on Russia has performed visiting surveys and information collection at coal related organizations inside Japan and in overseas countries on production technology levels, trends and technology exchange needs in overseas coal producing countries. The project is intended to serve for improvement in the contents of and smooth execution of the engineer exchange project in the 'coal mine technology field. It was carried out by expertise people as the site surveys and the engineer reception and exchange surveys. Because of the economic crisis that has hit Russia in 1998, unprofitable coal mines were closed one after another under the coal mine scrap and build policy under the initiative of the World Bank. This situation is giving serious impacts on coal mines in the Far East Russia and the coastal areas. However, the importance of coal as the primary energy source has not been changed at all in the Far East Russia. Thus, the areas have fallen into a situation that they must rely on a great amount of introduced and imported coals as a result of weakening in coal mines in the Far Eastern area on the other hand. This paper reports mainly the situation in which the coal industries in the coastal areas are placed, and the possibilities of technology exchange. (NEDO)

    This report summarizes the workshop and technical tour held in Japan for technical interexchange of domestic and overseas engineers. From the information obtained, the higher productivity of coal mines is dependent on selective mining under blessed geological conditions, however, basically establishment of an advanced management technique for inexpensive stable operation. Both preliminary collection of geological information and introduction of advanced facilities even under unstable conditions are necessary. The balance and optimization of the whole system, and an excellent human nature for operation are also essential. Use of roof bolt supports is diffusing as improvement technology of excavation speed and roof control technology over the world. However, for introduction of new technologies, collection of test results and various kinds of training are necessary. Methane gas in coal seams as the main theme of the Hokkaido workshop is a precious unused natural resource, and important for prevention of global warming and coal mine protection measures. Its use is dependent on development of gas drainage technology. (NEDO)

    Indonesia rich in coal resources consumed 70-million tons of coal in 1999, which covered 17% of its total energy demand. It is estimated that as much as 120-million tons will be produced in 2005, and it is expected that underground mining will increase. Under such circumstances, Indonesia strongly desires that Japan's underground mining technologies be transferred to Indonesia. For the transfer of technologies especially involving production control and management out of Japan's underground mining technologies, Japan dispatched engineers to Indonesia under a mining engineer exchange project, and received and trained Indonesian engineers. Under the engineer exchange project, five engineers were dispatched to Indonesia and gave lectures and on-site training in the period July 9 through August 5, 2000. Japan received seven engineers, who were given lectures and training at the Ikeshima mining field of Matsushima Coal Mining Company in the period November 12 through December 12, 2000. (NEDO)

    China is surveyed for promotion of joint implementation, which is one of the flexibility measures in the Kyoto Protocol, the Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change. The project aims to collect methane for global warming suppression and to use it as town gas and for power generation as well. The survey covers the 2 coalfields of Yangquan and Panjiang. The Yangquan coalfield is the largest anthracite yielding base in China, with 6 mines in operation. Power generation centering on a 100MW plant is discussed, and generation fired by a mixture of debris out of the coal preparation facility and gas is compared with another fired by town gas, on the assumption that 130-million m{sup 3} is available under the current circumstances. In the case of the Panjiang coalfield, which is expected to develop into a large coal base in the southern part of China, power generation centering on a 50MW plant fired by a mixture of debris and gas is discussed, on the assumption that 63-million m{sup 3} is collectable from the existing 5 mines. Use of town gas is also studied. When Japan's coalbed methane collection technology is applied, the gas drainage rate will be elevated to 40-35% or higher. It is desired that the use of gas drainage will be further diffused for the prevention of disasters of coal mine gas explosion. It is hoped that the use of environmentally friendly energies will be enhanced. (NEDO)

    In Europe, international division is in progress as the result of market internationalization, and the coal market is experiencing an increasingly intensive competition in the storm of deregulation. The coal industry of Britain is away from a crisis for the time being, thanks to a new 5-year contract concluded with the electric utilities who are the primary purchasers, but it has to compete with imported coal and natural gas. The industry is also hit by the control imposed on the development of new opencast coal mines. Production is on the decline in the German coal market, which is one the largest in Western Europe, due to reduced subsidies, unfavorable geological conditions, lowered price, etc. The German coal industry is positively striving to exploit coal mines overseas and to export coal mining technologies. In Spain and France, the coal industry is forced to shrink and, in France, there is a plan to terminate coal mining completely in 2005. In Poland, the introduction of market economy has resulted in the influx of low-price coal from Russia etc., and all the Polish mines are now in the red. Its joining the European Union in the near future will further increase the pressure from other nations. It is learned that in Britain, Germany, etc., coal businesses are accelerating their transfer of technology to developing countries and are positively strengthening their presence abroad. (NEDO)

    This project has been performed with an intention of making visiting surveys and information collection at coal related organizations in overseas coal producing countries on production technology levels and trends. The project is intended to serve for improvement in the contents of and smooth execution of the engineer exchange project in the 'coal mine technology field. It was carried out by the site surveys. The surveys revealed that the situation of the American coal industry is expected of stable increase in the demand and supply in the future, but the coal price is on the falling trend, and therefore, the industry is compelled to further increase the intensity and enhance the productivity. The industry is strongly influenced by the amended air pollution prevention act and nature destruction problems, hence further coal mine curtailment is estimated. Under such a background, it was found that the long-wall mining process progressing toward larger scale and higher productivity, and the high-wall mining process that provides higher productivity at lower cost and has less impact on the environmental problems can continue development in mountainous areas, particularly in the Appalachian area. The high-wall mining process mines coal at exposed facings on the side of a mountain by using a continuous miner, and transports the coal using machines. (NEDO)

    Harmful compounds, e.g., dioxins and nitrogen oxides, released into the air are causing severer environmental problems on a global scale. In order to solve these problems, it is necessary to efficiently remove the released compounds in the vicinity of the living environments, while preventing, as far as possible, their formation at the sources. An attempt has been made to develop porous membranes impregnated with composites of a variety of metallic oxides showing activities as photocatalysts and for dark reactions by the ion engineering method, in order to drastically solve the above problems. Described herein are the FY 1998 results. Thin films of various titanium oxide crystals (anatase, rutile, and their combinations) are formed on Si substrates by the ion engineering method, as the photocatalysts for decomposition of aldehyde and water (for hydrogen production), to validate the optimum crystalline structures for the photocatalysis. Porous bodies of Ni and carbon are also impregnated with anatase TiO{sub 2} for decomposition of harmful gaseous compounds and water, to validate the effects of the porous membranes provided with catalytic functions.

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

    Plasticity of ceramic dough is determined by the deformation of the buffer domain that consists of aggregate or gel. Effect of the deformability of each buffer domain on the plasticity of alumina dough, in presence of various additives, was investigated. Those additives were konjak, agar, curdlan and super-absorbent polymer. Moderately deformable additives such as konjak and agar worked as buffer domains, and plasticity was generated. However, soft and brittle additives such as curdlan and super-absorbent polymer could not improve plasticity because of their lower ability in generating the buffer domains. It was clarified that the deformability of buffer domain directly influences plasticity. (author)

    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.

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

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

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

    The present survey was intended to enhance accuracy of analysis and interpretation of the geological structures in the northern and north-western parts of this area, and the status of coal seam existence. The survey used the most part of the earthquake exploration data obtained in fiscal 1988, and parts of the earthquake exploration data obtained in fiscal 1983 and fiscal 1985 in the vicinities thereof, and incorporated a new treatment method to perform re-analysis. The quaternary deposit seam has thickness of 80 to 610 m, and the Palaeogene deposit seam has thickness of 600 to 1600 m as a whole. The structure of the foundation bed is nearly parallel with the structure of the top of a coal seam in the Palaeogene deposit seam, having a distance of 300 m between the seams. The surveys combining the test drillings having been done to date and the physical exploration estimates that the coal seam groups are distributed over the entire area of Ariake Sea. Possibility has heightened, that the coal seam groups may spread over the land area. The collapsed fault passing east-west the northern most area of the Ariake Sea and having drop of 200 to 300 m forms the northern boundary of the Miike coal field. However, the coal seam groups are estimated to spread north of the coal field as a sedimentary basin, and continue to the northern side of the fault. (NEDO)

    In relation with coping with global environmental problems in recent years, needs are increasing more than ever for enhancing fossil energy utilization rates, developing and expanding utilization of petroleum substituting energies that can substitute fossil energies. Since Japan is particularly a large energy consuming country, and cannot escape from depending on import for the majority of its energy resources, it is an urgent issue to enhance the energy utilization efficiency and further promote development and utilization of new energies. To do this, it is indispensable to exchange such item of information as identification of actual status in other countries of handling the petroleum substituting energies. Taking up geothermal energy, fiscal 1998 invited four experts from EU countries. Visits were made for about two weeks on Japanese research institutes and business enterprises related to geothermal energy, and opinions and information were exchanged. A seminar was held on the final day, where the EU experts have made presentations on the current status and future prospects on geothermal research and development in EU. Greatly valuable suggestions were given for the Japan's future geothermal research and development. (NEDO)

    A survey was carried out to make available the information base that can collect, put into order and provide quickly and accurately the energy related information based on global environment problems in the Pacific Ocean region. Fiscal 1998 has performed a substituting energy demand and supply analysis in the Pacific Ocean region by adding the 1996 data, in addition to collection of the normal energy data. For the purpose of analyzing the petroleum substituting energy demand and supply in the Pacific Ocean region, data were collected from 17 countries for fiscal 1997 and the quarterly data for 1998. Retroactive data collection was also continued. The growth rate of primary energy supply in the Pacific Ocean region is 1.8% in average in the 1980's, and 3.8% in the 1990's. In contrast, the growth rate of petroleum substituting energies is 6.4% in the 80's and 6.2% in the former half of the 90's, being far higher than the growth rate of the primary energy supply. The share of the petroleum substituting energies accounting for in the primary energy supply has increased from 6.7% in 1980 to 12.1% in 1996. As the breakdown, nuclear power accounts for overwhelmingly large, followed by geothermal energy and new energies. (NEDO)

    The R and D project is implemented for manufacturing high-quality semiconductor crystalline materials of large size and uniform characteristics, in order to improve semiconductors as components for controlling power systems, and reduce power loss. The semiconductor melts, in particular silicon melt, is highly reactive, readily reacting with the atmosphere and crucible holding the melt, and it is difficult to collect their thermal properties. Therefore, an electro-magnetic levitation furnace working under a microgravity is used, to dispense with a crucible for measurement of their properties in the absence of thermal convection. The preliminary tests using the furnace produce surface tensions of the melts, because Ge is less reactive than silicon, stable in the form of a GeSbTe compound, and not wettable with Al{sub 2}O{sub 3}, MgO, SiO{sub 2} or Si{sub 3}N{sub 4}. The measurement of electric resistance of InSb indicates that InSb has characteristics of a semiconductor when it is solid and a metal when it is liquid, as is the case with Si. The program codes are developed by each researcher, and combined with each other to establish the comprehensive thermal flow analysis program, which includes all of the aspects of the internal CZ furnace structure for growing the crystals.

    With an objective of realizing super large capacity recording technologies largely exceeding the current limits of optical recording and magnetic recording, studies were conducted on application of near-field optics. In the study on recording by using near-field light, it was verified that a mark with approximately the same size as an aperture diameter can be formed on a phase change recording film when a fiber probe with an aperture diameter of about 200 nm is used. However, it was found that the recording using this system takes excessive amount of time. When laser light collected on an objective lens was irradiated pulse-wise, a mark with a minimum width of about 20 nm was observed with high contrast. This will mean that a record with recording density of one terabit/in {sup 2} can be read out. Other studies performed include those on evaluation of effects of polarized light and surface shape on near-field read-out, simulation, mechanism of crystallization in a phase change recording film, recording and playback with ultra-high resolution by using a conformable near-field aperture, fabrication of a flat aperture type near-field light probe array, and the evaluation thereon. 22 refs., 27 figs.

    In order to evaluate presence or absence and extent, if present, of the effects of drilling a geothermal well, changes in flowing-out rate of hot spring and others were surveyed at the hot spring resorts in the Kuwanosawa area and its peripheries, extending around 18 km{sup 2} area in the mountains approximately 20 km to the south of City of Yuzawa, Akita Pref. Three sites were selected; the hot spring resort of Takamatu, a hot spring resort at the foot of mountain, and another hot spring resort near the dry riverbed of the Takamatu River, where hot spring spontaneously flows out in all of these sites, from the 1,500 m deep boring at the first site, and in the area where steam is gushing out in the second site. The surveyed items were rate of flowing-out, temperature, electroconductivity, pH and various ion concentrations of the hot spring, and precipitation. The survey was conducted 19 times from August 9, 1999 to July 12, 2000. For the effects of drilling the geothermal test well and drawing-up the hot water, some surveyed items changed significantly in these 3 resorts. These changes, however, largely result from seasonal reasons as well as conditions within each hot spring well, and not from the drilling of the geothermal test well N11-KN-1 and drawing-up of the hot water.

In biomass energy, production of ethanol from corn, and development of biodiesel are in progress in the USA and Europe, respectively. Use of biomass should be promoted because of its global environment compatibility and sustainable productivity. In the future bio-market, genome analysis and its application are most important, however, Japan is behind in such technology in the world. The Joint approach by industry, university and government is necessary from the viewpoint of a future marketability and international competitiveness. Promotion of a public acceptance and nurture of creative talents are also important. (NEDO)

    Product evaluation has been investigated from a viewpoint of compatibility with human life by considering human being as the subject of life. This report describes the investigation results. Product evaluation is defined as evaluating products on a consumer-oriented viewpoint and informing consumers of the evaluation results. According to a questionnaire survey with regard to daily living products, products in the low degree of satisfaction in their usage were electric tooth brush, video camera, electric rice jar, vacuum cleaner, and electric iron. Contents of dissatisfaction with these products were classified by aspect, i.e., human aspect regarding human body/recognition, life aspect regarding functions of products and how to use them, and sensitivity aspect such as appearance of products. Thus, points at issue were clarified. As regards the human aspect, incompatibility between the size/form of products and human body/posture, and recognition psychological incompatibility such as difficulty in understanding function or operation of products were pointed out. Establishment of a method for measuring and evaluating the human`s body functions and the compatibility with products, and necessity of the acquisition of human`s body characteristic data and the consolidation positions are also described. 4 refs., 42 figs., 30 tabs.

    This is to comply with the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) protocol. For the recovery of exhaust heat from the air blast furnace air heater, combustion control will be improved and an exhaust heat recovery facility will be installed. For the recovery of converter-generated gas, the casting process in the open hearth will be changed to a continuous casting process in the converter, and a generated gas recovery facility will be installed. The power plant facilities will be improved. It is expected that these three jobs will reduce greenhouse gases at 178, 583, and 602-thousand tons/year in terms of CO2, respectively, and energy consumption at 826, 8954, and 8152 TJ/year (13% level reduction), respectively. Time periods required for the recovery of the investments will be 31.2, 8.7, and 7.2 years, respectively, and this means that the investments will not be so profitable. As for cost performance, however, they will save energy at 262, 208, and 420 GJ/year/million yen, respectively, and reduce greenhouse gases at 56.4, 13.5, and 31.0 tons/year/million yen in terms of CO2, respectively, and this means that the three jobs will achieve high cost performance. Some more jobs are found to probably contribute to energy efficiency enhancement and cost performance improvement, which include a top pressure recovery turbine, pulverized coal injection, continuous casting in the steelmaking process, improvement in the yield of slabs in the rolling process, and a hot charger.

    The paper grasps the present situation of economy and industry in Kazakhstan and studies a policy for developing the industrial machine manufacturing industry of the country. Since the independence in 1992, the country is now at the great turning point in politics, economy, society and industry. The country is forced to convert from the industrial structure of one local area where much of its own discretion had not been given under the economy system of power centralization to the industrial structure which meets the international economic market system as an independent country. Making good use of agricultural and industrial property in the former U.S.S.R., the country needs to export energy resource like oil, natural gas and coal, and abundant ore resource like iron and non-ferrous metal, which were added with values. As the technical base for it, fostering and strengthening of the industrial machine manufacturing industry is important. At present, the situation is that because of the economic sluggishness, the country cannot manufacture domestically even basic mechanical parts and simply-manufactured parts which are required by the domestic energy industry, machine manufacturing industry, and other industries. The technical program to be proposed by Japan is planned to be worked out later based on the basic research made in fiscal 1993. 6 figs., 14 tabs.

    This project aims at establishment of new basic biotechnology by preparing an artificial variation/selection system in a laboratory based on the molecular level information on bio-evolution mechanism. This report summarized the fiscal 1998 results. For analysis of the experimental system for in vitro evolution of protein molecules, it is necessary to make adaptive walk efficient based on the obtained feature information of a fitness landscape. The fitness landscape was studied using the heat resistance and specific activity of LOD (lactate oxidase) as fitness, and a practical system for screening clones was established. A crone superior in heat resistance and specific activity was obtained by repeating random variation, effective amino acid substitution and screening. Cystatin B is a specific inhibitor of cysteine protease (including Cathepsin K). Improvement of a specificity of Cystatin B to Cathepsin K was attempted by partially substituting its amino acid sequence. In the case of cysteine where two amino acid residues for mutation are linked closely, a mutant activity was additive to amino acid substitution. (NEDO)

    Penang Island, in the northern part of Malaysia, where the urbanization is well advanced and sites for waste disposal are scarce, was selected as a target area for the research on introduction of solid waste (henceforth called reuse) power generation system. About 500 tons of refuse are generated daily in Penang Island, and are disposed of in a coastal landfill site at Jelutong near the center of George Town, the state capital. Although the landfill site is already beyond its capacity, it is still in use because there are no other disposal sites in the island. For this reason, there is widespread concern about coastal environmental pollution. Therefore, the Municipal Council of Penang Island has studied feasibility of transferring refuse to a new landfill site at the peninsula side of Penang State across the Penang Bridge over the sea channel which separates the island and the peninsula. However, this transfer and landfill method has not been realized yet. In view of improvement of these situations regarding solid waste management is Penang Island, it is proposed in this report, as the result of the research, introduction of power generation system fueled already-accumulated refuse in this disposal site together with refuse to be collected every day. The study was started in September 1999 and was completed in March 2000. Japan Environmental Consultants, Ltd. investigated the present situation of solid waste management in Penang Island, analyzed refuse properties, and studied the refuse fueled power generation technology with the cooperation of SIRIM (Environmental and Energy Technology Centre) and PTM (Pusat Tenaga Malaysia, Malaysia Energy Centre) in Malaysia. In concrete, the research team established a scheme of an integrated system most suitable for the refuse treatment including refuse power generation in Penang Island, the famous resort of northern Malaysia, and studied its feasibility. The proposed system is combination of selective pulverizing classifiers (SPC, a high-performance refuse classifier), refuse composting units, and gasification and ash melting furnaces with power generation equipment. In the proposed system, combustible gas converted from refuse in a fluidized bed gasification furnace is fed to the ash melting furnace, where ash is molt by combusting the gas at the temperature around 1,350 degrees C. The high temperature combustion gas generated in the ash melting furnace is used for power generation. The gasification and ash melting power generation system is characterized by the facts including. (1) The system does not require, like other systems, additional fuel for ash melting. (2) Leaching of hazardous heavy metals is prevented as they are enclosed in the ash molten slag. (3) As ash is molten at high temperature of 1,350 degrees C and solidified, emission of toxic substances such as dioxin can be prevented. (4) As the temperature of the gas used for power generation is very high, energy recovery efficiency is high. According to our study, 240 tons per day of combustible refuse can be used for power generation, and approximately 34,000 MWH/year of electricity, which is balance between generated power and station power consumption, can be sold to the commercial grid in Malaysia. The refuse which is not suitable for energy recovery is composted after separated with SPCs. Molten slag, compost, together with other hard refuse such as glasses and stones, initially separated by te refuse reception unit, are used as land reclamation material. During 20 years of project life, approximately 60 hectares of land can be reclaimed with such recycled material. When compared with the transferring and landfill method, the proposed system has more favorable features, in the field of economics, environmental protection and social development, in addition to the fact that energy is recoverable from refuse.

    The aim was to develop reliable materials high in resistance to hostile environments, greatly improved in their resistance to oxidation, abrasion, and corrosion at high temperatures. To achieve the goal, trace quantities of high melting point metals were implanted into the compound formed on the substrate surface or deep into the substrate material. This year's research and development is outlined below. Important technologies in the ion process involved materials which at high temperatures were very resistant to oxidation, abrasion, and corrosion. The high-temperature oxidation resistant material was studied for use with the automobile supercharger rotor. The study on the high-temperature abrasion resistant material involved Ti-N thin coatings: the optimization of coating conditions, slidability at room temperature, and slidability in a high-temperature atmosphere. As for the high-temperature corrosion resistant material, studies were made to use it for refuse-fueled power generation. The TiAl material was also studied: the effect of ion implantation on the improvement of its high-temperature oxidation resisting capability, analysis into oxidized alloy surface properties, ion implantation into complicatedly shaped items and the optimum material for them, and the surface treatment by ion beams for improving resistance to high-temperature corrosion.

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

    Described herein are the FY 1998 results of the studies on validating possibility of superhigh-temperature optomechanical composite materials, transparent in the visible to infrared wavelength region and having excellent mechanical properties, and possibility of producing practical matrix materials and considerations for their production. For development of the production processes, a composite of glass matrix reinforced with oxynitride glass fibers is investigated, where the matrix having a refractive index differential with the fibers of 10{sup -3} is selected. The composite is prepared by hot pressing the matrix powder put between the fiber bundles. Analysis of its light transmittance and mechanical properties indicates that the method is an optimum one for producing the optomechanical composite material. For creation of the heat-resistant, light-transmitting ceramic matrices needed for commercialization of the composite materials, an MgO-Al{sub 2}O{sub 3} spinel-based system is selected, for which the production process is investigated. It is found that the material light-transmittable in the visible to infrared wavelength region can be produced by hot pressing a hot-pressed MgO-Al{sub 2}O{sub 3} ceramic material. (NEDO)

    For the damageless fabrication of nanometer-electronics devices, low energy and damage-free surface reactions have been investigated as follows. (1) Negative ion etching of silicon has been investigated in SF{sub 6} and Cl{sub 2} plasma. (2) To establish the self-limiting reaction process which is necessary to realize the atomically layer-by-layer etching, the initial reaction of fluorine (F) atoms and F{sub 2} molecules with hydrogen (H)-terminated Si (111) has been studied. In both SF{sub 6} and Cl{sub 2} plasma etching, the etching reactivity of negative ions was proved to be higher than those of positive ions, since negative ions are atomical like the radical. A notch-free etching of n+ poly-silicon with 0.3{mu}m L and S pattern was successfully obtained by an alternative irradiation of positive and negative ions in SF{sub 6} plasma. For SiO{sub 2} and other oxide etching with negative ions the high rate was observed but not with high selectivity. Negative ion-assisted Si oxidation was found to be one order faster than radical and thermal oxidations. Based on the ATR and XPS measurements, F atom/H-terminated Si(111) surface reaction has been revealed. First F radicals penetrates just underneath of the Si-H bond, generating the B{sub 2} peak. Further exposure appear the B{sub 3} peak which arises from the bonding of a F atom with a Si-H bond at the five-coordination state. However, more exposure of F atoms caused higher order SiF{sub x}(x=l,2,3) products. Hence, F{sub 2} gas which was less reactive than F atoms was investigated. It was found out that the exposure of 5 % F{sub 2}/He to H-terminated Si (111) reached a plateau value at 5{sub x}10{sup 5} L where terminated H atoms quite disappeared. The SiF monolayer corresponded exactly to an atomic layer of Si(111) was formed. This indicates that the self-limiting process for the Si/F system has been realized first. (NEDO)

    Research is being conducted contributing to the adoption of plans for the introduction of new energy facilities to the industrial sector in the Chubu District. Fundamental data of manufacturing plants are collected. In Japan, the nationwide number of new energy facilities adopted in private establishments is 3,003 and the number of automobiles using clean energy sources is 1,530. Those in the Chubu District are 327 and 208, respectively. Although the survey shows that over 80% of establishments in the Chubu District are concerned with public awareness of new energy facilities, there is also some concern about the social contribution along with expectations of reduced costs through usage of new energy. As for perspectives for the future, 40% of the establishments which are not clear do not indicate optimism. Looking at the results of new energy introduction, factory excess heat/waste, utilization of heat from waste, and currently natural gas co-generation are promising. Photovoltaic power generation and solar heat utilization as well as heat from waste products are being studied for the future. 19 figs.

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

    A portable system was developed so as to prevent the urinary incontinence and enable the aged persons and patients to live their comfortable life. In the measurement of urinary volume, its correlativity with the change in impedance was confirmed with a small and light-weight prototype. As a result of improvement of the ultrasonic method, the measurement accuracy was heightened with miniaturization. The usefulness and safety could be clinically confirmed in the urination control by electric stimulation. Based on the above element technologies, the total system was then studied by interlinking the intravesical urinary volume measurement system and urination control system. Particularly for the patients of urgent urinary incontinence, an in vitro test was conducted with a system into which the electric stimulator was integrated. As a result, this system was good as a nursing system. Through an animal experiment on iontophoresis, the urination was known to be controllable with skin-permeating drugs. However, it was known that those drugs are pharmaceutically classified into the new DDS group by the Drugs, Cosmetics and Instruments Act. Therefore, the clinical application plan was partially revised for the present system using them and made to be a subject of future study.

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

    For the purpose of establishing a chemical recycling system for PET bottles (saturated polyester resin) of which the recovery amount is expected to increase in future, the R and D were made for establishment of a chemical recycling system, and the FY 1999 results were summarized. In the R and D of an economical treatment process by waste polyester resin decomposition/synthesis system, the information was obtained that the acid value of the decomposition liquid is suitable as the control index for determining the finish of the decomposition process, and the acid value of the synthesis liquid is suitable as the control index for determining the finish of the re-synthesis process. In the demonstrative study of physical properties/quality stabilization of the re-synthesized resin, conditions for operation with no very big dispersion in physical properties of re-synthesized resin such as viscosity and acid value were obtained. In the demonstrative study of a recovery/recycling system of low cost PET bottles, the area for recovery was expanded to Shirahama town and Yuasa town in addition to Tanabe town that recovered bottles in the previous fiscal year, and the recovery amount totaled 3 t/mo. As to the development of the application of the recycled resin, the recycled resin which has the quality at least equal to virgin resin in cutting processability was obtained, and products such as septic tank were trial-manufactured.

    Research and development has been performed with an objective to establish an economical waste PET bottle recovering and regenerating system. In the research of waste polyester resin decomposing conditions, researches were made by using a small five-liter testing machine on methods to decide the condition of completing the decomposition of PET bottle flakes, and methods to decrease the decomposition time, whereas it was verified that the decomposition is possible in one hour after temperature has been risen under a constant temperature condition. In the research of re-synthesizing conditions, experiments have verified that re-synthesis of PET bottle decomposed liquid into unsaturated polyester by means of acid can be performed under a constant temperature condition. Based on these achievements, design, construction, and trial operation of a plant with treatment capacity of 100 tons a year were executed between January and May, 1999, by which possibility of regenerating high quality unsaturated polyester resin was identified. With regard to the waste PET bottle recovering system, discussions were given on a system to sort and recover wastes at the first wastes generating points under coordination with neighboring cities, towns and villages, where the recovery amount of one ton a month was achieved as planned originally.

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

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

    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.

In regard to the chemical materials and products intrinsically containing a certain level of risk, R and D should be reinforced and accelerated in the future on the alternative materials/products reducing their toxicity. In this case, along with the importance of discussing compatibility of technological possibility with economical adaptability, sociological study seems to be necessary in incorporating environmental load reduction into economic evaluation.

    Survey was made for establishment of an effective fast search technique of practical catalysts. Catalyst technology is an important basic technology for industrial fields such as energy and environment fields. In many cases, catalysts have been developed by trial and error consuming a long time and huge research cost. Study was made on efficient analysis and measurement techniques, and systematic production technique of advanced catalysts based on these techniques. This survey was effective in finding a guidance for improving catalysts used in the previous processes, and facilitating searches for fields previously slow in development of catalysts. Advanced catalysts possible to actively selectively produce target products under high pressure/temperature conditions are much in demand. Recently in-situ analysis technology for observing molecules and material surfaces under ultrahigh-pressure/temperature conditions has been studied. Observational study was made on catalytic behavior under catalytic reaction condition using partial oxidation, selective hydrogenation and isomerization as model reactions. 111 refs., 103 figs., 9 tabs.

    The permanent magnets have been investigated and developed, for eventual commercialization of a 10 MWh power storage system by high-temperature superconducting flywheel. The permanent magnet rotors have been already developed in the previous years using a praseodymium-based magnet (Pr magnet) and neodymium-based sintered magnet (Nd sintered magnet), and the target rotational speed of 30,000 rpm has been attained. For development of the magnetic circuit to produce a stronger and smoother magnetic field, magnetic flux density of the Nd sintered magnet is measured. It shows a lower magnetic flux irregularity than the Pd magnet, but there is still room for further improvement. For development of large-size permanent magnet fabrication techniques, it is confirmed that the large-size Nd sintered magnet can be easily magnetized by partial magnetizing, as is the case with the Pr magnet. In this year, the irregular magnetic flux is three-dimensionally simulated, based on the results obtained in the previous years, to find that the simulated results are in good agreement with the observed ones. The measures to solve the problems are also investigated. It is also confirmed that the large-size ring magnet can be easily magnetized by partial magnetization. (NEDO)

    An organism is a molecular mechanical system consisting of nucleic acid, peptide and protein having a self-forming and a self-repairing function. For the purpose of creating cells, tissues and molecular mechanism alternating these biological functions, their basic technology was developed. Concretely, studies were made on three-dimensional cellular structural module engineering and biomolecular mechanism and design. Studies on biological soft tissue resulted in success by giving atmospheric glow discharge treatment to the inner surface of a tubular PVC. An artificial vitreous body was created using PVA hydrogels. In addition, liver cells were successfully cultured for the first time in the world. Studies on biological hard tissue revealed that osteopontin plays a role of a trigger for the initial differentiation of the osteoblast cell. Further, a basic experiment was carried out on the initial response of the cartilage cell. In the research on the molecular mechanism, examination was made on the mechanism of a double-head molecular motor. Examination was also made on the adjustment of the hydrogenase LB film as an electricity/hydrogen energy conversion element and on the biomolecular mechanism and design. (NEDO)

    In FY 1995, the final year of the project as to recycling of large size waste such as discarded home electric appliances as well as energy recovery, operation methods of the comprehensive system were investigated, to design practical systems. Constituent elements and the comprehensive system, which was completed in the prior fiscal year, were operated to evaluate the pilot plant with respect to the categories of operation performance, separation efficiency, and recovery efficiency. Three categories of discarded items were refrigerators, washing machines, and television sets. As a result, it was confirmed that the pilot plant checked out favorably, satisfying all the target values given at the initial stage. For the research of practical system, conceptual design of the practical system, its practical scale, and the economic factors were investigated. In the case of a plant scale of 3 t/h, a trial balance was made of setting equipment costs, fixed costs, fluctuation costs, processing costs, and profit from sale of recovered items with value. As a result, the net cost was about 1,700 yen per wasted hold appliance. In addition, problems in the construction of a practical plant were extracted. 68 figs., 74 tabs.

    The paper described the results of the FY 1999 research on the fouling by marine aufwuchs. The survey is aimed at searching the nature world for active substances for biological antifouling. The fouling mechanism in the ocean is as follows. The adsorption of organisms called the conditioning film first occurs on the surface, and next, bacteria and diatom around the surface form biofilm and cover. After that, biological fouling by large aufwuchs occurs. Therefore, the control of biofilm formation was regarded as most important, and with this as a guidepost, the search was conducted. Using biofilm anti-formation activity and periphytic bacteria anti-growth activity as guideposts, some compounds were searched for. Being aimed at Porifera, in particular, new compounds were isolated from it. Since few of other organisms attaches on the surface of sponge, there is a great possibility of Porifera's producing any anti-fouling substances. Further, it is thought that symbiotic microorganisms of sponge (40% of the total weight) produce various biologically active substances. Synthetic phenethyl amine derivatives were also studied.

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

    Since ion implantation causes material degradation by formation of crystalline defects, and hydrogen embrittlement deteriorates material strength, reduction of such defects has been positively studied. Study was made on a new active application of hydrogen separation into ion implantation defects. After H ion implantation of a proper depth into single-crystalline Si and SiC and successive annealing, single-crystalline films of sub-micron to several micron thick were obtained by hydrogen-induced delamination at the implantation depth due to hydrogen embrittlement in crystalline defects. The implantation depth is dependent on implantation energy. H atom forms (111) face defect through connection with dangling bond of crystalline defects. This crystal face defect forms a delamination plane through (100) face cleavage. This hydrogen embrittlement delamination by ion implantation is applicable to production of light-weight high-efficiency single-crystalline Si solar cells, and large single-crystalline SiC wafers as new resource saving process. 33 refs., 19 figs., 2 tabs.

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

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

    For the development of continuous flow artificial heart, the purposes of this study are confirmation of species difference in hemolysis, development of LASER photometry for hemolysis and thrombogenesis, immunological investigation of platelet function during nonpulsatile pumping and development of adequate microcapsule system for the simulation of hemolysis. The relative liabilities of red blood cells of 3 kinds of animals to the same shear stress are; human; 1.0, ovine; 1.75, bovine; 0.22.For comparison of pump systems, therefore, the species difference in hemolysis should be considered. Laser light intensity gradually increased with hemolysis during nonpulsatile perfusion. On the other hand, the intensity abruptly decreased on thrombus formation. From these findings, it becomes possible to monitor processes of hemolysis and thrombogenesis dynamically and non-invasively. As the laser photometry is able to be utilized not only for in vitro study but also for in vivo study, it becomes efficient monitoring system. Immunological examination of platelet function revealed that GMP-140 and MP are the most sensitive parameters to detect the interaction between platelets and nonpulsatile blood pump. The development of microcapsule system for simulation of hemolysis study is still in progress. By application of the results of these studies, it also becomes possible to conduct more efficient and reliable research for the development of continuous flow artificial heart. (NEDO)

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

    The purpose of this study is to develop advanced processing technologies to fabricate ultra-large-scale-integrated circuit on large-diameter wafers with high-precision and no-fluctuations at low temperatures. We develop the plasma process technologies to generate high-density uniform plasma with high-controllability to realize very precise manufacturing and low-temperature processing, and technologies for the high-performance process apparatus in which wafer surface is never exposed to atmosphere and therefore ultraclean wafer surface in atomic level are always maintained and molecules and ions react on the wafer surface in perfect accordance with reaction theories. We have developed a plasma process equipment using RLSA (Radial Line Slot Antenna) for formations of high-quality thin films. As a result, high-density uniform plasma has been successfully produced. The kinetic energy of bombarding ions onto the semiconductor substrate surface can be reduced to 7eV in this microwave plasma. Therefore high-quality thin films without any damages can be successfully formed. Next, we have developed magnetron plasma equipment with dipole-ring magnet for deep sub-micron etching. It was revealed that deviation of the plasma due to E x B drifts of electrons was perfectly improved by applying RF to an upper ring electrode. It was also revealed that to realize a closed manufacturing system, in which the wafers are transported in an ultra clean N{sub 2} environment and the wafer surface are never exposed to atmosphere, is essential for the deep sub-micron semiconductor manufacturing with high-reliability. Additionally, very fine-structure and bonding state of Si (100) surface which are terminated by hydrogen or fluorine, chorine was made clear by calculations using quantum chemistry under the three-dimensional periodic boundary condition.

    The objective of the research is first to build a highly parallel processing system using 100 personal computers and an ATM switch. The former is a commodity for computer, while the latter can be regarded as a commodity for future communication systems. Second is to implement parallel relational database management system and parallel data mining system over the 100-PC cluster system. Third is to run decision-support queries typicalto data warehouses, to run association rule mining, and to prove the effectiveness of the proposed architecture as a next generation parallel database/datamining server. Performance/cost ratio of PC is significantly improved compared with workstations and proprietry systems due to its mass production. The cost of ATM switch is also considerably decreasing since ATM is being widely accepted as a communication-on infrastructure. By combining 100 PCs as computing commodities and ATM switch as a communication commodity, we built large sca-le parallel processing system inexpensively. Each mode employs the Pentium Pro CPU and the communication badwidth between PC's is more than 120Mbits/sec. A new parallel relational DBMS is design-ed and implemented. TPC-D, which is a standard benchmark for decision support applicants (100GBytes) is executed. Our system attained much higher performance than current commercial systems which are also much more expensive than ours. In addition, we developed a novel parallel data mining algorithm to extract associate rules. We implemented it in our system and succeeded toattain high performance. Thus it is verified that ATM connected PC cluster is very promising as a next generation platform for large scale database/dataminig server. (NEDO)

    The objects of this project are to elucidate the self-organization mechanisms of a living body, e.g., functional adaptation to environments and self-restoration, to utilize the molecular interactions in a living body, and thereby to establish the basic technologies for developing molecular motor functions, e.g., artificial organs. Described herein are the FY 1996 results. For creation of living soft tissues, N-ePTFE and Gf are found to be good base materials for cell growth in the serum-free culture, and may be applicable to bio-reactors. Sugar-bound high-molecular-weight compounds and artificial hyaloid body are created. For hard tissue materials, e.g., artificial articulation, the macrophage is activated by englobing worn debris of polyethylene, to activate the broken bone cells that absorb the bone, causing the artificial articulation to become loose. For researches on molecular motor mechanisms, it is considered that myosin changes the head morphology to give a driving force to the muscle, and this concept is studied in detail. The photosynthesizing protein is a molecule related to light and electricity, and is useful as the material to apply the living functions to industrial technologies. The technologies for assembling molecules are studied by utilizing the self-organization functions of living molecules. Development of other molecular machines is also attempted. (NEDO)

    Research and development efforts are exerted to produce advanced dental materials equipped with such functions as plaque reduction, bactericidal effect, and early formation of hydroxyapatite (HAP). In the study of fluorine ion implantation for plaque reduction, it is found that in a specimen implanted with fluorine ions the adhesion of carius streptococci is reduced to 1/3-1/10 for the achievement of remarkable improvement. In particular, carious streptococcus multiplication is suppressed when the metal shield layer is replaced with a titanium mesh. For the realization of a thin film formation method for osteoblast multiplication through reforming the material surface in the study of bone-forming dental materials, film formation conditions under which a P/Ca rate which is quite near that of ameloblast are achieved by use of a high frequency magnetron sputtering device. A titanium plate coated with a thus-formed film is annealed for a great increase in its wet contact angle, and then adhesion of bacteria is reduced and an osteoblast multiplication rate is increased by 20% or more, as compared with the case of no treatment in a petri dish.
