    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.

    A regression equation that can calculate the daily accumulated absorption heat of Trombe Wall was given, and the performance estimated chart of Trombe Wall in which the daily unit effect of Trombe Wall can be visually recognized was proposed. The absorption heat was multivariate-analyzed by two variables of solar radiation of that day and the previous day. The data obtained from simulation was used for analysis. The absorption heat was analyzed using the meteorological data at eight spots (Sapporo, Sendai, Niigata, Tokyo, Shizuoka, Kochi, Fukushima, and Kagoshima). In this case, the result of multivariate analysis almost coincided with the simulation result. A chart that predicts the absorption heat of Trombe Wall in eight cities from the daily accumulated global solar radiation of that day and the previous day was then created as the performance estimated chart of Trombe Wall. As a result, the solar radiation of that day little influences the absorption heat when the Trombe Wall increases in thickness. Conversely, the solar radiation of the previous day significantly influences the absorption heat. In future, an equivalent heat loss coefficient will be calculated from the performance estimated chart. 2 refs., 16 figs., 2 tabs.

    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 the effective utilization of solar energy at houses, a heating system using an air hybrid collector (capable of simultaneously performing heat collection and photovoltaic power generation). As the specimen house, a wooden house of a total floor area of 120m{sup 2} was simulated. Collected air is fanned into a crushed stone heat accumulator (capable of storing one day`s collection) or into a living room. The output of solar cell arrays is put into a heat pump (capable of handling a maximum hourly load of 36,327kJ/h) via an inverter so as to drive the fan (corresponding to average insolation on the heat collecting plate of 10.7MJ/hm{sup 2} and heat collecting efficiency of 40%), and shortage in power if any is supplied from the system interconnection. A hybrid collector, as compared with the conventional air collector, is lower in thermal efficiency but the merit that it exhibits with respect to power generation is far greater than what is needed to counterbalance the demerit. When the hybrid system is in heating operation, there is an ideal heat cycle of collection, accumulation, and radiation when the load is light, but the balance between accumulation and radiation is disturbed when the load is heavy. 4 refs., 8 figs., 3 tabs.

    A wall-jet has a wide range of application such as to control of the boundary layer of a wing of an aeroplane, control of temperature of the vanes of a gas turbine and flow inside a fluid control device. This field of flow comprises a wall layer on the wall side having the characteristics of a boundary layer and an outer layer on the external side which is like a free jet, the two layers being separated by a boundary where the flow is at a maximum speed. This study was carried out to clarify the effect of riblets experimentally using as a base jet a wall jet which was one of basic shearing flows. In particular, studied were the degrees of change in the mean and fluctuating velocities near the wall surface and reduction of drag. The following results were obtained. A significant difference was recognized in the vicinity of the wall in the mean velocity distribution between the mean velocities on the riblet surface and on the smooth surface. The fluctuating velocity component in the x direction on the riblet surface decreased by about a maximum of 20% when compared with that on the smooth surface. In contrast, the fluctuating velocity in the y direction and Reynolds shearing stress both on the riblet and smooth surfaces were substantially in agreement with each other within the range of this experiment. 28 refs., 12 figs., 1 tab.

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

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

    This paper describes the correlation and evaluation technology, extracted from the achievements in the development of a technology to apply human senses to measurements in fiscal 1992. In evaluating the warm heat comfort by living scenes of workers according to the human body thermal model, the research environment was improved by expanding the systems to measure physiological volume and the warm heat environment. Findings were acquired on the relationship between body fat rate and skin temperature, and actions of artery-vein anastomosed (AVA) blood vessels. These findings were incorporated into the research to elevate the levels of applicability of the human body thermal model. In estimating the sense volume by using skin temperatures, physiological volume being the factor of variation in face skin temperatures was elucidated, and a system to measure these variations was structured. In order to acquire the physiological volume being the factor of variation in face skin temperatures, brain wave topography measurement and {alpha} frequency fluctuation and arousal evaluation and measurement were experimented, where the effectiveness thereof was verified. Analysis was also made on blood flow rate and perspiration volume related to skin temperature variation mechanism, which has provided a number of fundamental data. For the stress measuring technology, and stress relaxation by means of scent, researches were moved forward mainly on environment improvement and preliminary discussions. (NEDO)

    This study is intended to establish a basic technology for innovative high-efficiency separation membrane materials that can be used in areas in which application of membrane separation has been impossible. The water/ethanol separation membrane (for water selective permeation) and water/acetic acid separation membrane (for water selective permeation) achieved separation coefficient and permeation velocity of the world's highest level. The water/ethanol separation membrane (for ethanol selective permeation), although its separation coefficient is lower than the world's highest performance, has high permeation velocity, providing the performance of the worldwide level as seen from the comprehensive viewpoint. The carbon monoxide/nitrogen separation membrane achieved separation coefficient and permeation velocity of the world's highest level. The oxygen/nitrogen separation membrane requires further enhancement in the permeation velocity and stability. Establishment has been performed on separation technologies for membrane separation of non-water soluble aqueous solutions, optical division by using chiral crown ether, high-performance liquid separation by means of plasma surface treatment, and particle separation. Basic analysis has been advanced also on evaluation technologies for gaseous body separation membrane and liquid separation membrane, of which future progress is expected. (NEDO)

    The paper established the basic evaluation method of composite particles manifesting functions which the existing mono-componet particles do not have and aimed at the international standardization of the measuring method of them. To be concrete, the development was studied of methods to evaluate the mechanical bonding state of different composition in composite particles, the chemical bonding state of different composition and the electromagnetic state of the surface of composite particles. As a result, in the evaluation method of the mechanical bonding state of different composition in composite particles, methods to evaluate the bonding state and the large composite bonding state of the coated particle layer were developed to clarify the details to be standardized for each method. In the evaluation method of the chemical bonding state of different composition in composite particles, the electronic energy loss spectroscopy was an effective method to evaluate the chemical bonding state in composite particles of oxide ceramics. Further, in the evaluation method of the electromagnetic field of the surface of composite particles, standard experimental procedures for observing the electromagnetic field by interference of electronic waves were proposed, and the evaluation of the electromagnetic field state of composite particles used ranging from low temperature to high temperature was made possible. 41 refs., 85 figs., 14 tabs.

    Developments were performed during fiscal 1993 on a system to investigate correlation among external stimulating environment, physiological effects and sense volume based on a physiological reaction model. The development works included improvement of the model, discussions on a method to estimate parameters inside living organisms, and a method to collect subjectivity volume data. Prototypes thereof were fabricated, evaluated, and experimented, where nearly complete achievement of the targeted functions was verified. In developing a technology to evaluate quantitatively the comfort of composite environments composed mainly of warm heat environment, discussions were given on an integration evaluating expression in order not to make handling the environmental physical volume too complex. The expression models the evaluation of governing sense volume in individual environments of warm heat, light beam, and sound, and calculates the composite environment evaluation indexes by using the evaluation indexes obtained from the modeling as the descriptive variables. In developing the space-type human interface adapted to human senses, a computer system to realize the interface and the platform for function mounting were developed. The development items were broken down respectively on the basic technologies for functional aspect and surveillance and control function mounting, and the software systems. The human comfort meter achieved the basic design target. (NEDO)

    Research, development and evaluation were performed with an objective of establishing the basic technology related to light-reactive materials that control the structures and status of aggregation of molecules by using actions of light, and can be used for ultra-high density recording, high resolution indication and light switches. In elucidating the mechanism of light deterioration reaction of photochromic molecules, it was disclosed that 6-nitrospirobenzopyran has the light deterioration caused from the excitation triplet state. This disclosure presents a possibility of preventing the light deterioration. New derivatives that show photochromism were synthesized, and thin films were produced by using the LB process. This indicates a possibility of producing the photochromic materials as the high multiplex recording material. With regard to PHB materials, an evaluation technology having spectrum resolution of the world's highest level was established and measurements were performed. Hole formation was verified for the first time in the world at the temperature higher than the liquid nitrogen temperature by using a PHB material of ionic porphin/polyvinyl alcohol systems. This verification indicates a feasibility of practically usable PHB materials. (NEDO)

    To take up methodology of quality engineering as ISO standards, the basic document was worked out which regulates general items for the method to evaluate the operation of various systems as function for proposal to ISO. A method is developed for evaluating the design quality by function and predicting/optimizing the quality of finished products. For the evaluation of slippage from ideal function, the SN ratio and Maharanobis`s distance are used. In the two basic working groups (WG), a document on general methods to evaluate function was made. To reinforce the basic document, WGs divided into five by content/business were set up. Each WG collected examples from the past, studied methods to evaluate function in each field, and recorded them in the document. Five experiments for each WG were conducted to verify effectiveness of the above-mentioned method to evaluate function recorded in the document. As a result, the draft to present to ISO was worked out since the experimental WGs proved the effectiveness of the method to evaluate function in each field. 85 refs., 147 figs., 185 tabs.

    Receiving subsidies from MITI, NEDO carried out this project in fiscal 1995 and 1996 as a joint research with Technology Research Association for Phosphoric Acid Fuel Cell Power Generation System and others. The project aimed at developing the accelerated test method which can evaluate in a short time the cell life of phosphoric acid fuel cells (PAFC) and the lowering of characteristics. The accelerated test method of PAFC life is thought to be a tool indispensable for the promotion of commercialization, but the accelerated test method like the usual material evaluation has not yet been established. To solve this problem, procedures were developed to rationally plan the accelerated test on short stacks of full scale based on the small cell test data. Here, to rationally estimate the operational state under actual conditions based on the data on the accelerated test, it is necessary to fully understand the mechanism of deterioration of PAFC. By conducting in parallel the element study for the basic elucidation of cell deterioration phenomena, obtained was the useful information/knowledge which back up the results of the accelerated test scientifically. 168 figs., 33 tabs.

    The first term has performed research and development placing emphasis on that 'the basic study on membrane separation is to be performed systematically to elucidate governing factors in membrane separation'. With respect to water/ethanol separation by using the penetration gasifying method, it was indicated that excellent separation performance can be exhibited by using natural polymers having sugar chain skeleton as a raw material, and by controlling the membrane structure by means of membrane manufacturing methods. For enhancement of performance in water selective permeation type separation membrane, it was shown experimentally that it is important to select a membrane suitable for the object of separation and a separation method that uses the selected membrane. Regarding the water/ethanol separation, it was shown theoretically that the penetration gasifying method can save more energy than the conventional distillation method, where the development target was presented. It was recognized that impregnation type liquid membrane using crown ether can separate amino acid optical isomers. High separation performance was obtained in carbon monoxide/nitrogen separation by using fluid carrier that uses cuprous iodine/1-methyl imidazole. (NEDO)

    For the purpose of proposing the optical evaluation method of appearance of the apparel as an international standard, studies were made of the following: 3D determination/assessment method, development of mannequin holders, development of shape-retentive cubic replicas, washing/drying conditions, etc. As to the shape retention, cubic replicas for collars and cuffs were manufactured and inputted as image data. Besides, as to the evaluation items such as wrinkles, seam-puckering and pleats, the class determining algorithm was made by comparison between the measuring data and the results of the human-sight measurement. These were embodied into mannequin holders and integrated into the optical 3D instrumental system, which was discussed as a 3D determination/assessment system. By the development of the 3D measuring system and image analysis program, a comprehensive evaluation system was developed which can determine/assess the performance of shape stability of the apparel optically as absolute evaluation. This method will be internationally proposed as an optical evaluation method of the appearance of the apparel. 86 figs., 8 tabs.

    In this research, the photovoltaic power system is experimentally installed at various facilities (public facilities such as public hall, school and museum), and operated on a long term basis under the actual loads. Various kinds of data are collected/analyzed and used as the data useful for the full-scale introduction and spread. The photovoltaic power generation field test project for public facilities using the photovoltaic power system was started in FY 1992 by NEDO. Systems at 116 sites started operation by FY 1996, and in FY 1997 systems were installed at a total of 70 sites. The paper outlined the project and described the results of the collection/analyses of the operational data obtained at 145 sites where systems were installed from FY 1995 to FY 1997. The term of analysis in FY 1999 was made from April 1999 to December 1999, being different from usual, to avoid the Y2K problem on data collecting software, measuring use personal computer, etc. Further, since there are no sites where no systems were newly installed in and after FY 1998, there are no analyses of economical efficiency in and after FY 1999.

    The paper studied the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. Chemical composition and coating thickness (g/m{sup 2}) of 14 kinds of specimens including alloy coatings and organic coating with zinc and aluminum as base were analyzed by the above-mentioned methods to examine the relation between the both. As the chemical analysis method, used was inductively coupled plasma atomic emission spectrometry. To study the relation between the methods, it was found to be necessary to recognize morphology at the boundary between the coating and base steel using, for example, scanning electron microscope (SEM) and electro-probe micro-analysis (EPMA). To measure traceability of the analysis method, with the chemical analysis method as a judgement method, it is necessary to make reference materials by coating materials, to use the calibration graph confirmed by the materials and to adopt the glow discharge optical emission spectrometry. On the basis of such way of thinking, drafts were worked out for the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. 7 refs., 117 figs., 33 tabs.

    For the purpose of promoting photovoltaic power generation, analysis and evaluation were conducted on the data of the project of the field test in public facilities for example. This paper describes the fiscal 2000 results. The equivalent array operation time was 2.98 h/day and, by multiplying it by the output of the standard test condition, a generated output was obtained. The system generating efficiency was 0.102 while the inverter energy efficiency was 0.917 on the average. The average array performance ratio was 0.778 and the system performance ratio was 0.714. The analysis on cost effectiveness of the installed systems has an important bearing upon the future introduction, promotion and development. The power generating cost (the annual cost was calculated as the sum of the capital cost, the direct cost, and the administrative expenses) decreased as the installation year progressed, with the average at the sites installed in fiscal 1997 at 93 yen/kWh. The system cost (calculated by dividing the construction cost by the array capacity) also decreased as the installation year became more recent. The annual maintenance cost showed a wide range from 500 yen to 30,000 yen/kW. Answers from the sites that the systems were running smoothly were 38 to 45%, while those that trouble occurrence was frequent were 2.4% on the generating systems and 12.9% on the measuring systems.

    For standardization under information security evaluation criteria, an evaluating technique CEM (Common Methodology for Information Technology Security Evaluation) was constructed as ISI/IEC15408. The method, however, is abstract in content and the evaluation work thereunder requires much time and accompanies economic difficulties. In dealing with the situation, investigations were conducted into security evaluation related techniques and manufacturing/quality control techniques in use at information processing product developing sites, and a CEM technique is materialized. Using the proposed technique, developers themselves can evaluate security in the development process and workloads imposed on evaluating organizations may be reduced because evidential items necessary for 3rd party evaluation may be gathered. Since the developed technique is verified by an official evaluating organization, it is expected to be an effective techniques not contradicting existing operating techniques. It may be also said that this technique is a method whereby developers will collect evidential items necessary for their development efforts. The result will be presented in the form of a proposal for an evaluating techniques standard for ISO/IEC JTC1 SC27. (NEDO)

    The field tests on photovoltaic power generation systems for public facilities have begun in fiscal 1992 by NEDO. The systems including those under construction are installed in 116 sites. Analyses were given on 75 sites which have been operated up to fiscal 1996. Analyses of the operation characteristics were performed by using performance parameters derived by developing the basic expressions into each configuration element. For the insolation on slanted surface, the range from 3.0 to 4.5 kWh/m{sup 2}/D accounts for 65% of the total insolation. For the equivalent array operation time, the range from 2.5 to 4.0 h/D accounted for 81%. For the equivalent system operation time, the range from 9.0 to 12.0 h/D accounted for 85%. The range for inverter active efficiency from 0.84 to 0.96 accounted for 79%. The inverter load rate was accounted for 88% by 0.20 to 0.35. The output coefficient was accounted for 82% by 0.7 to 1.0 in the array, and 87% by 0.6 to 0.9 in the system. The power generation cost has decreased to 200 yen per kwh in fiscal 1995 from 340 yen per kwh in fiscal 1992, largely contributed by reduced installation cost. (NEDO)

    The paper proposed the international standardization for the use of next generation image media by evaluating health effects of the use of next generation image media such as head mounted display and 3D monitor. A method to comprehensively evaluate health effects was studied with the design friendly to humans and standardization on safety as final targets. Themes were divided into the autonomous nervous system and the measuring system. The development was carried out of a method to evaluate the autonomous nervous function by the dynamic state of blood circulation and pupillary reflex as well as the development of portable sphygmomanometer and pupillometer. Using these developmental instruments and conventional instruments, measurement was made of blood pressure, cardiac output, respiration, pupil size, eyeball movement and focus accommodation. A possibility was suggested of obtaining the uniform elucidation also in case analytical changes of individual parameters cannot be extracted or consistency cannot be seen in the course of changes. The paper determined basic standards for the experimental use stereoscopic image, made measuring use 3D images, and collected realtime data by the overall simultaneous measuring system constructed. 109 refs., 166 figs., 18 tabs.

    Japanese paint users demand products of higher-quality than users in the U.S. and Europe, and therefore, paint makeres in Japan are making strenuous efforts to improve the product quality in terms of homogeneity, appearence and durability of the surface of paint films. However, the evaluation of paint surfaces is conducted by the qualitative sensory evaluation, resulting in obtaining no appropriate evaluation. Accordingly, the following were developed as new evaluation methods which give rational and economical indicators, contribute to shortening of the period for development of new products, and aim at the international standardization: 1) quantitative evaluation of the paint drying process; 2) image analysis of the degraded part of paint films; 3) surface analysis of paint films. In 1), a kinetic friction measuring quantitative evaluation of the surface of paint films was developed. In 2), the development of an exclusive program by the image analysis made the quantitative evaluation with high accuracy/reliability possible. In 3), an evaluation method was developed in which differences among the specimens can be detected by the chemiluminescent measurement in an extremely early stage of exposure when the gloss change just begins. As to the chalking, a new evaluation was developed in which the degree of chalking can quantitatively be evaluated by attaching a special adhesion tape to the degraded part of paint films and by the optical measurement of the degree of transparency. 101 refs., 341 figs., 118 tabs.

    This paper introduces a subjective evaluation on a thermal environment. Providing human being with an appropriate and pleasant environment requires considerations from three aspects of economy, health, and comfort. Related with these are the productively optimal temperature, the physiologically optimal temperature, and the subjectively optimal temperature. While a human being makes subjective judgments on his or her environment through physiological reactions, the kinds of these subjective judgments include those on perception, evaluation, preference, receptivity, and permissibility. The subjective evaluation is measured by declaration of subjects. An evaluation method using a category scale or an SD scale is used for the measurement. The evaluation on cold-hot feeling and comfort using the category scale and that using the SD scale are explained, whereas the evaluation on preference relative to environmental temperatures is carried out by rating that the present environment should be made warmer'', can remain unchanged'' or should be made cooler''. 22 refs., 5 figs., 5 tabs.

    The photovoltaic/thermal hybrid panel (PV/T) is an energy converter that was designed for the composite use of electricity and heat. In this paper, the validity of PV/T designed for trial was evaluated based on an exergetic theory. As the result of an experiment, the electric exergetic value of PV/T and PV is each 65.8 kWh/m{sup 2} and 58.6 kWh/m{sup 2}. The former is higher than the latter by 11.2%. The total exergetic value of PV/T is also 1.2 and 8.2 times as high as those of a PV and solar collector (SC), respectively. The calculation result of the optimum temperature operation showed that the exergetic value of PV/T is 3.1 times as high as the electric exergetic value. Therefore, the operation must be performed with the electric and thermal exergetic values set in a ratio of 3.1 to 1. In this paper, the operating mode is handled in which importance was more attached to the electric exergy than the thermal exergy. The flow rate of a heating medium on PV/T is not thus the flow control that maximizes the PV/T exergy. In the future, studies including these points will be promoted. 7 refs., 7 figs., 3 tabs.

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

    Discussions were given on corrosion fatigue crack life by using corrosion fatigue crack initiation test and analysis. The test used 13Cr-based stainless steel as a test material, and aquamarine at 60{degree}C as a corrosion environment. The fatigue test was performed under a tension loading condition with a stress ratio of 0.1 and an iterative velocity of 1.7 Hz by using a 10-tonf fatigue testing machine. In the corrosion fatigue crack initiation test, a pit has been generated on a boundary of an exposed part and a painted part for masking, hence direct observation was impossible on pit growth behavior. Therefore, an intrinsic crack model was introduced from pit dimensions as observed from a fracture face, and analysis was made on corrosion fatigue crack growth by using the linear fracture dynamics, wherein clarification was made on a phenomenon occurring after the crack growth passes the pit growth until the test piece is fractured. A proposal was made to define the time when fatigue crack initiates and grows from the bottom of a pit as a result of surpassing the growth of corrosion pit as the corrosion fatigue crack life. 4 refs., 7 figs., 1 tab.

    Human auditory sensation has both extremely excellent performance and general versatility as sound analyzer. At present, it is impossible to make equipment with the same functions as human being, and describe an auditory sensation function as acoustic sensor even by any physical analysis techniques. However, extraction of auditory sensation parameters is becoming possible by using psychoacoustics and binaural signal processing. This paper mainly explains the calculation method of sound quality evaluation parameters derived from psychoacoustic results based on a sound quality evaluation system under development by the authors. This system is based on binaural measurement by dummy head, and calculates psychoacoustic parameters such as loudness, sharpness, roughness, fluctuation strength and tonality through frequency analysis of the measured stereo signals. The system also calculates 2-D parameters such as sensory pleasantness and unbiased annoyance based on the above parameters. 12 refs., 4 figs.

    Sinters of silicon nitrides have excellent properties as a structural material, but their technological repercussion effect is not as much as has been expected. The cause is in insufficient understanding on the mutual relationship between microstructures and mechanical properties. Therefore, methods of controlling structures were first discussed in the studies on synthesis of high-tenacity ceramics. In order to achieve high reliability in material strength, discussions were given on means to have a structure developed with high reproducibility. Development was performed on {beta} powder which shows no abnormal grain growth and is stable at elevated temperatures. Then, quantitative evaluation was made on factors to manifest a self-compounding structure with columnar particles grown in ultrafine particles. The relationship between its chemical composition, microstructure and mechanical properties was also discussed. Particle shapes of silicon carbides and their fracture tenacity values were considered theoretically by using a drawing model. To evaluate the microstructure, it is important to determine the grain boundary composition, whereas an electric field radiation type high-performance electron microscope was developed. In discussing the fracture mechanism, a model was structured for behavior of covalent binding crystals against external stress. 164 refs., 95 figs., 10 tabs.

    Jellyfish assaulting in a great number during summer into water intakes at power plants is disposed of by land filling in plant premises. Discussions on treatment methods and tests using test machines have been carried out over four years to save disposition area and prevent odors. While it is well known that jellyfish melts in fresh water, the basic tests identified that heating and alkali treatment is effective, the fish shrinks and reduces rapidly when boiled to 80{degree}C or higher, it can be cut and crushed easily, and its solute has a high COD. A test machine having a treatment capacity of 5 tons an hour was used. The machine consists of a cutter unit, a supply pump, a draining box, a heating tank, a circulation pump and a mesh conveyer, and is capable of batch and continuous treatments. A full-size based test machine improved of transferring and solid treating functions was tested to a satisfactory result of achieving the initial intention.

    Nearly 20 years have passed since the regular study in magnetic refrigeration commenced. However it has not been put to practical use, because the technology depends largely not only on magnetic materials but also on superconduction magnets, heat switches, and etc. This paper reviews the outline of studies in magnetic refrigeration and their future. The principle of magnetic refrigeration and the merit and demerit are described first under the heading of the special features of magnetic refrigeration. Magnetic materials developed so far are also introduced. Then a Carnot cycle magnetic refrigeration is explained. The study in space satellites by NASA, adiabatic demagnetization refrigerators and etc. are introduced. In the section of magnetic regenerative refrigerators, continuous Carnot active magnetic regenerators (AMR) and Brayton AMR are described.

    This is No.91 report of National Institute for Research in Inorganic Materials, concerning cobalt oxide. For the growth of single crystal by the Czochralski method, shape of interface and contamination of impurities are affected by the convection of molten liquid in the atmosphere. Various oxides besides CoO were investigated. Solid solutions of Cr2O3 and Al2O3 into CoO were also studied. Non-linear optic and dielectric properties of single crystals, such as Ba2NaNb5O15 and LiNbO3, were examined. It was considered that the positive electron having positive electric charge can be used for the study on the negative electric charge defect in materials. However, the positive electron itself is rare, which results in the too low efficiency of measurement. Efficiency improvement of 50 times was achieved by introducing a high performance 2D position detector, which was still low efficiency of one-hundredth compared with photoelectron spectroscopy. It was found that the aggregation structure of positive ion defects in CoO is a misunderstanding of phenomenon caused by the electronic state in bulk crystals. As a result of the study on the optical properties of f-electron transition metals, transparent ceramics with addition of various rare earth ions were described. 162 refs., 106 figs., 14 tabs.

    Mr. Takashi Tachibana, a critic, enumerates two reasons for why the U.S.A. is maintaining the high research level. One is the U.S. research institution in which foreigners can perform their actions freely. Another is the American frontier spirit that evaluates highly the challenge to new things. In the fields where the Central Research Institute of Electric Power Industry of Japan has achieved world-wide excellent accomplishments, many are the cases in which foreign researchers participate and work actively as the visiting researchers or the Science and Technology Agency (STA) fellows. In the latter case, the Central Research Institute of Electric Power Industry has introduced since a few years ago a system in which challenges can be made on unique researches that the researchers can draw their inspirations by themselves. Results are beginning to appear in several subjects, including the environmental hormone measuring method utilizing biotechnology. The 21st century requires solution of different problems in the electric power business, such as energy and environment issues. It would become increasingly important to work positively on creative and advanced researches and further strengthen the research power as the base for problem solution under the internationally opened research institution where first-class researchers inside and outside the country will get together.

    An attempt was made to visualize distribution of cracks in a rock slope by applying geophysical survey onto a rock slope. Geophysical logging and seismic survey using the reflection method were used as the methods for the geophysical survey. The rock slope subjected to the survey is located in a gorge along the Yoshino river in Yamashiro Town, Tokushima Prefecture. The slope has a width of 25 m and a height of 30 m. Its overhang in a nose form may has a possibility of causing collapse due to sliding. Cracks developed by horizontal schistosity were detected by performing geophysical logging on VSP, calipers, natural gamma-ray spectra, temperature and borehole in a borehole drilled vertically from the top of the slope. The seismic survey using the reflection method detected the cracks by emphasizing joints in the perpendicular direction. A possibility was shown to visualize the crack distribution with high resolution by using the above geophysical survey on the rock slope. In order to detect the crack distribution with still higher resolution, development into a three-dimensional exploration in the future is desired, not to speak of improvement in signal receivers, and discussions on geometry. 1 ref., 6 figs.

    Coal seam gas is also called coal bed methane gas, indicating the gas existing in coal beds. The gas is distinguished from the oil field based gas, and also called non-conventional type gas. Its confirmed reserve is estimated to be 24 trillion m {sup 3}, with the trend of its development seen worldwide as utilization of unused resource. For the necessity of cultivating relevant technologies in Japan, this paper considers processes of production, movement, stockpiling, and accumulation of the gas. Its productibility is controlled by thickness of a coal bed, degree of coalification, gas content, permeability, groundwater flow, and deposition structure. Gas generation potential is evaluated by existing conditions of coal and degree of coalification, and methane production by biological origin and thermal origin. Economically viable methane gas is mainly of the latter origin. Evaluating gas reserve potential requires identification of the whole mechanism of adsorption, accumulation and movement of methane gas. The gas is expected of effect on environmental aspects in addition to availability as utilization of unused energy. 5 figs.

    The effects of tsunami and seaquake on large floating structures are theoretically studied, where these effects are followed in terms of local strength using the equation proposed by Sells to predict surface shapes changed by seaquake-caused uplift of the seabottom. The equation is combined with the one for tsunami propagation, to better predict the tsunami motion. The simulation results indicate the necessity of considering the effects of tsunami for the design of a large floating structure. The authors discuss that the effect of tsunami is minimized when a floating structure is set at a depth of at least 40 to 50m, chain length should be determined by equalizing the breaking weight with the load at which the structure starts to move, and a structure should be set at a position where it is not attacked by transverse waves. They also discuss that seaquake intensity should be predicted by the equation of motion of compressible fluid, and, noting local strength of a floating structure, it will not be damaged when it is at least 16mm thick under the conditions of 2m as seabottom uplift and 0.5m as draft depth. 15 refs., 9 figs., 2 tabs.

    In order to evaluate disaster potential and disaster prevention potential of landslides, which are complicatedly composed of natural factors and social ones, an evaluating method of the potentials is proposed by applying the multiple logistic model. Furthermore, a method making the potential map using this evaluation is shown. The multiple logistic model is based on the conception of multiple risks, and so the disaster potential is expressed with probability. The disaster prevention potential is evaluated by using the disaster potential. Taking a typical landslide district as an instance, some potential maps colored by each potential are shown. By these maps, effects of the preventive measures against disasters and changes in the disaster prevention potential according to the industrial structure as well as the population are evaluated. Furthermore, combination of the other disaster potentials obtained by changing the surveying interval or factors makes it possible to draw various disaster maps and disaster prevention ones for different purposes. 15 refs., 17 figs., 3 tabs.

    The multi-offset hydrophone VSP experiments were carried out using a 750m deep borehole as the oscillation receiver, which penetrates the Nojima fault, to detect water-permeable cracks and evaluate their characteristics. Soil around the borehole is of granodiorite, and fault clay is found at a depth in a range from 623 to 624m. A total of 4 dynamite tunnels were provided around the borehole as the focus. The VSP results show that the tube waves are generated at 22 depths, including the depth at which fault clay is found. However, these waves are generated at only 6 depths in an approximately 150m long fracture zone, suggesting that the cracks in the zone are not necessarily permeable. It is also found that crack angle determined by the analysis of tube waves almost coincides with that of fault clay determined by the core, BHTV and FMI, and that permeability is of the order of 100md at a depth of fault clay or shallower. 3 refs., 2 figs., 2 tabs.

    The on-and-off timing of vehicle headlamp control systems varies with weather conditions. Cloudy weather has a wider light energy distribution from visible to infrared radiation than clear weather. Silicon photodiodes, which can detect visible to infrared radiation, have larger output currents on cloudy evenings than on clear evenings under the same brightness conditions. The systems should be designed with such factors in mind as spectral characteristics of windshield, filters, sensor, and eyesight. 4 refs., 9 figs.

    Research and development have been pursued of plastic materials degradable in sea water and their application to the fishery material field in consideration of protection of the marine environment. Tests are conducted on degradation speed of bioplastics in sea water. Concerning a sample copolymeric polyester, by giving 4-hydroxy butyric acid, 1,4-butanediol, 1,6-hexanediol and {gamma}-a butyrolactone group to A.eutrophus, copolymeric polyester P (3HB-co-4HB), a mixture of molecular units of 3-hydroxybutyrate (3HB) and 4-hydroxybutyrate (4HB) is fermented. Test results show that it degrades at the same speed, being independent of molecular structures of biopolyester and copolymerization composition, different from the case of degradation in soil. It is clarified that the microorganism which degrades biopolyester in sea water is streptomyces, a kind of actinomycetes. 3 refs., 5 figs.

    Elaboration of the evaluation guidelines for activities implemented jointly (AIJ) was researched to prevent the earth from warming. AIJ is the means to globally promote countermeasures against global warming cost-effectively by optimally combining every country`s technology, know-how and fund. AIJ was established in the 1st Conference of the Parties (COPI) of the United Nations Framework Convention on Climate Change in March, 1995. The pilot phase of AIJ is first carried out by voluntary workers jointly with developing countries under the agreement of the parties. The current situation of activities is reported in COPI as materials for evaluation of AIJ. To promote AIJ, elaboration of the evaluation guidelines for AIJ Japan program is also necessary for Japan. This research arranged the contents of the evaluation guidelines and the method of classifying projects for AIJ Japan program, and carried out some case studies of promising projects to reduce greenhouse gas emission for future proposal. 3 figs., 31 tabs.

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

    For the foundation improvement works by grouting in a borehole, evaluation of grouting effect is one of the most important management items. The grouting design and works are sometimes reconsidered depending on the evaluation of grouting effect during the test injection. The purpose of the evaluation of grouting effect is to grasp the range of improvement and consolidation after the injection, and to judge and estimate the strength and permeability of the consolidation part. This paper describes the judgment method of the strength using PS logging results and borehole televiewer (BHTV) logging results. The reflection intensity (Ir) by the BHTV logging increased after the grouting, which showed a same tendency as that using S-wave and P-wave velocities (Vs and Vp) before and after the grouting. This was considered to demonstrate the grouting effect. A relation was obtained between the Vs, Vp and Ir before and after the grouting, which was expressed by following equation. Ir=0.143{times}Vs-70=0.093{times}Vp-110. The relation with the dynamic elastic coefficient (Ed) was also obtained as follow; Ir=0.0013{times}Ed. 9 figs.

    Electron paramagnetic resonance (EPR) of coals was considered by using iodine doping technique. Sub-bituminous coal (WA) and bituminous coal (UF) were used to observe EPR spectra using microwaves. With the UF coal, strength of the narrow component of the spectra was found constant regardless of amount of the doped iodine, wherein radicals without interaction with iodine were detected. Strength of the broad component increased with the iodine doping amount, where in deviation of {pi} electrons was detected, which have been generated as a result of interaction between aromatic rings and iodine in the coals. Spin concentration of the WA coal with low coalification degree is constant regardless of the iodine doping amount, and the interaction of the iodine with the aromatic rings was found small. The higher the coalification degree, the more the aromatic ring structure grows, and electron donor capability for the iodine increases. In a system with the entire spin being uniform, the spectrum height shows a saturation phenomenon against increase in microwave output. A non-uniform system, in which the oriented spin forms small groups and is in local thermal equilibrium, does not show saturation, but increases monotonously. 2 refs., 5 figs.

    Regardless of whether the study on the hydraulics and pneumatics in Japan has arrived at an advanced level in the world or not, so as to lead the world, the strategy and practice corps suitable for it is required. The study on the hydraulics and pneumatics is strongly felt barely to have been supported by the interest and effort of each individual sparsely scattered so far. In order to deploy and develop continuously the study on the hydraulics and pneumatics in Japan, the project researchwork with a study strategy is needed. A present state of Japan is short of the cooperative hydraulics and pneumatics research center, which can be freely utilized and made the most of by the researchers all over the countries, or of the study organization being a match for it. Fortunately in Japan, as a special academic circle, there is the Japan Hydraulics and Pneumatics Society, only one in the world. As a part of its activity, in recent years, the hydraulics and pneumatics information center as well has been established, also the information collection and dispatch function is being expanded and strengthened. On an elongation line on activity like this, an establishment of the hydraulics and pneumatics research center is expected. 3 refs.

    This paper reports the achievements in fiscal 2000 in development of a technology to evaluate reliability of petroleum refining facilities. The development efforts were made mainly on analyses by simulation and neural net (NN) that utilize computers. In the high-temperature system facilities, the creep damage generation is governed by different factors including impurities. The evaluation on joint life requires simultaneous use of low temperature zone long-time test. Verification was made on application of non-destructive inspection, such as use of ultrasonic waves in the accelerated creep zone. Defect detecting capability was identified when an ultrasonic wave flaw detection model is used for buried piping. In the pulse eddy current flaw detection, a coil most superb in totality was selected by means of simulation, by which corrosion and wall thickness of piping and devices were detected from outside the sheathing materials. Development was made on a technology to diagnose and evaluate corrosion of tank in operation by using the AE method. The remaining life of transformers is determined by how seriously the coil insulating paper has been deteriorated, and furfural in the oil was found effective for the parameters. Particularly, application of the NN was revealed to be effective in estimating electric motor deterioration. A high-temperature sulfide corrosion rate estimating model was developed from the operation and measurement data of the facilities by applying the NN and TCBM. (NEDO)

    The relation between dynamic compression modulus and hardness and repulsive elastic modulus of flexible polyurethane foam was investigated by viscoelasticity measurement. The dynamic compression modulus varies depending on the initial shrinkage. In a larger shrinkage region, its increase was remarkably large. The dynamic compression modulus is positively correlated with the hardness, but it is reversely correlated with the repulsive elastic modulus. The dynamic compression modulus can be effectively used for evaluating the product quality. A simple two-dimensional model is proposed for flexible polyurethane foam. To the model, the finite element method (FEM) employing the plane stress element was applied. The calculated Young modulus from the model agrees well with calculated values of Thomas-Gent and of Lederman. However, it was significantly larger than the dynamic modulus. A FEM analysis employing plane rahmen element considering the skeleton bending was also performed. 15 refs., 8 figs., 1 tab.

    A 70 kW-class photovoltaic (PV) power generation system of the Tsukuba Research Cooperation Center, Agency of Industrial Science and Technology was evaluated using hourly measurement data. Hourly solar irradiation, mean PV module temperature, hourly array generated power, hourly PV system generated power were selected as the measurement items, to examine the validity of measurement method. Furthermore, based on these measurement data, the loss factors were estimated, which reduce the system efficiency. They included the losses due to the shadow effect, the deterioration of module efficiency with the raise of temperature, the mismatch of tracking control of the maximum power point, and the reduction of inverter efficiency with the input power phenomena. To estimate these loss factors from hourly measurement data, the system was evaluated by defining characteristic parameters. As a result, it was found that the main factors were the shadow effect and the mismatch loss, which reduce the mean annual output factor of the system to 65%. 3 refs., 6 figs., 1 tab.

    Performance of a solar heating system with a hydrothermal source heat pump was evaluated and compared with that of a direct solar heating system. The sun-dependency rates ({Sigma}D and {Sigma}H)of the direct system and heat pump (HP)-provided system were expressed as a function of the rate ({alpha}) of the auxiliary heat against the collected heat and as a function of the performance coefficient and {alpha}, respectively. When the sun-dependency rates are compared, it is found that the HP-provided system is the more advantageous when {Sigma}H/{Sigma}D>1. The relationship between the {alpha}`s of the two systems was clarified and computation was performed to compare the sun-dependency rates on condition that the two are equal in the heat collecting area. Although the sun-dependence rate cannot be elevated to 100% in the HP-provided system, it achieves a sun-dependency rate higher than that of the direct system even when the heat collecting area is small. In cases where the building is economically limited, for instance, with respect to the area for solar collector installation, it is advantageous to employ the HP-provided system. 5 figs., 1 tab.

    The ability that architectural space improves the thermal environment in comparison with outdoor environment is called the `capability of controlling thermal environment.` As the value becomes higher, the indoor thermal environment is more improved. In this paper, the controlling capability of six building envelopes with different window systems was compared. The heat transfer in the wall and window system is approximated using a lumped mass model of heat capacity to obtain a heat balance equation and combined with the heat balance equation in indoor air for backward difference. The wall surface temperature and indoor air temperature in a calculation model are then calculated. A radiation absorption coefficient is used for mutual radiation on each wall. In the model, the adjoining room or first- and second-floor rooms were made the same in conditions as the model on the assumption that the one-side lighted office in an RC reference floor is in the non-illumination and non-airconditioning state. In summer, the controlling capability remarkably varies depending on the window system. For the window facing the south, the annual capability is more advanced than in other directions and the indoor thermal environment is improved on the average. 7 refs., 12 figs., 1 tab.

    Discussed is a method for evaluating wind noise in passenger car compartment based on human auditory characteristics. In the study, noise in the compartment of a passenger car travelling at a constant speed is collected by use of a dummy head, and the collected noise is analyzed in view of the masking effect, directional sensation produced by binaural hearing, etc. A masked spectrum of noise in the compartment of a 6-cylinder vehicle travelling at 120km/h is analyzed, and it is found that some frequency bands, especially the band centering on 300Hz, are masked by a loud noise component falling in a low frequency band of 180Hz or lower. By use of masked spectrum analysis, the level of noise that is actually audible to human ears can be calculated. The noise level thus determined by masked spectrum analysis and the noise direction determined by a binaural signal processing model are examined, and then it is found that the noise direction is clearly determined when the noise belongs in a 450Hz band or higher where wind noise prevails. On the bases of the above-mentioned results and the directional sensation produced by binaural hearing, a `binaural wind noise evaluation method` is compiled. 20 refs., 9 figs., 1 tab.

    A new technique has been developed, which allows simultaneous measurements of individual potentials of the cathode and anode, and temperature of center of the practical lithium ion cells. The developed technique was applied to commercialized lithium ion cells as received and degraded by high rate charge/discharge cycles, to confirm efficiency of the technique. For the developed technique, metal lithium was attached on the surface of stainless steel sheathed thermocouple with a diameter of 1 mm, and this was inserted in the center of the cell through a hole at the bottom of cathode can to measure the temperature of center of the cell as well as to use itself as a reference electrode. The modified cells could provide stable charge/discharge cycles for more than two months during the test. Thus, the developed technique was applied to commercialized lithium ion cells as received and degraded by cycles. It was found that increasing of lithium ion insertion/desertion resistance on the cathode and/or increasing of electric resistance of the cathode were the main reason of the degradation of lithium ion cells investigated. Effectiveness of this technique for diagnosis of degradation of cells was confirmed. 5 refs., 16 figs., 1 tab.

    Chlorinated organic compounds has high priority for toxicity screening among environmental hazardous chemicals. In the present study, we used immortalized rat hepatocytes as a liver model in vitro to evaluate the toxicity of nine chlorinated organic compounds. Toxicity of nine chlorinated organic compounds were evaluated to cellular viability of immortalized rat hapatocytes. The potency of the toxicity based on 50% inhibitory concentration (IC50) value was in the following order: triclocalban>triclosan>3,4-dichloroaniline>2,5-diclorophenol> 2,5-dichloroanisole>p-dichlorobenzene> p-chloroaniline>o-dichlorobenzene=tris (2-chloroethyl) phosphate. The rank order of cytotoxic potency of nine chemicals was compared with toxicity information using animals. The rank order of cytotoxic potency did not relative to the order referenced mean lethal dose (LD50) as an index of acute toxicity of rats or mice. However, the rank order of cytotoxic potency relatively correlated non-observed adverse effect level (NOAEL) under the exposure duration adjusted for chronic toxicity in vivo. These data suggests that the origin of testing cell had better to make match target organ of toxic chemicals for extrapolation from data of bioassay in vitro to in vivo. 16 refs., 2 figs., 3 tabs.

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

    This paper reports model experiments to evaluate flow rates of fluids passing through a fracture by using a Doppler borehole televiewer (DBHTV). A supersonic transducer disposed on a well axis transmits transmission pulses, and a transducer receives scattered waves generated by particulates in water and waves reflected on a well wall. This signal is applied with time gating to extract only the scattered waves from particulates in the vicinity of the well wall. Deriving spectra in the recorded Doppler signal obtains flow velocity components in the direction of the well radius. A model was made with a polyvinylchloride pipe with a diameter of 14.6 cm to simulate a well, to which an aluminum pipe with an inner diameter of 2 mm is connected to be used as a simulated fracture, and mud water is circulated in the pipe. The result of deriving a passed flow volume in this model by integrating flow rate distribution derived by using the above method to a predetermined range in the vicinity of the fracture showed a good proportional relationship with actual flow rate in the simulated fracture. 1 ref., 7 figs.

    Study was made on the relation between chemical structures of fuels and flame propagation velocities in gasoline engines. Recently lean burn engines have been developed, however, their combustion is largely unstable for every combustion cycle under a lean burn condition. A decrease in thermal efficiency and an increase in unburnt hydrocarbon emission due to reduction of a combustion rate are also major problems. Increasing a flame velocity in engines is one of their solutions. As the study result, flame velocities of light olefin and naphthene were higher, while those of isooctane, MTBE and ETBE were lower. A heat production period and time to dQmax were shorter in light olefin and naphthene, while longer in isooctane, MTBE and ETBE. Substances with higher flame velocities had higher thermal efficiencies under a lean burn condition because reduction of a thermal efficiency due to dissociation from Otto cycle is small. THC concentration in emission gas was lower in 4-methyl-1-pentane, 2-methyl-2-butane and cyclopentane with faster flame velocities, while higher in isooctane with the lower velocity. 3 refs., 8 figs., 1 tab.

    This paper enumerates different kinds of substances that are believed to cause cancer, and discusses how they behave in their quantitative evaluation on carcinogenic effects in human bodies. About 600 carcinogenic substances have been discovered from experimental animals, of which about 50 substances have been identified to clearly cause human cancer. The quantitative risk evaluation is performed by combining mainly two items; information of intensities of carcinogenic effects and human intake of the substances. An amount of a substance that raises a carcinogenic frequency by as much as a one million fraction when lifetime experimental animals are dosed with the substance is called a virtually safe dosage (VSD). According to calculations, the amount of BHA, a food additive for example, that is taken by Japanese people from different kinds of oils is 1/70 of the VSD, a very small contribution to occurrences of human cancer. Carcinogenic substances cannot explain, with very few exceptions, the occurrence of human cancer quantitatively. Living practices should rather be changed and improved. 5 refs.

A study was made of the polymerization of sugar ester monomers, and a polymer with a molecular weight of scores of thousands was obtained. The biodegradability of sugar containing polymers was confirmed. Using an enzyme, a polymer with a molecular weight of 1200 was obtained. Using a lipase derived from psudomonas cepacia, a polylactic acid was obtained from lactide. A high-function polylactic acid was obtained in a reaction between methyl lactate and divinyladipate. In a reaction between butanediol and lactide, several lactic oligomers different in molecular weight were synthesized, which were then brought into reaction with divinylcarboxylic acid in the presence of an enzyme for the production of polymerizable lactic oligomers. Similarly, polymerizable lactic oligomer derivatives were obtained from glucose and lactide. The oligomers and derivatives were brought into polymerization in the presence of a radical polymerization initiator for the production of polymeric gels, respectively. (NEDO)

    Microcosm system was applied to assess effect of anionic surfactant (LAS) on aquatic ecosystem. Anionic surfactant such as LAS was added to an flask microcosm consisting of four species of bacteria as decomposer, one species of ciliate protozoa (Cyclidium glaucoma), two rotifers (Philodina sp. and Lepadella sp.) and one aquatic oligochaete (Aeolosoma hemprichi) as predator, and a green alga (Chlorella sp.) and a filamentous blue-green alga (Tolypothrix sp.) as producer, comparing with that of an natural lake model ecosystem derived from natural lake water. In the flask microcosm system and the natural lake model ecosystem, biodegradation rates of LAS were almost same and NOECs (no observed effect concentration) of LAS were also below 1.5 mg{center_dot} l{sup -1}. It was found that flask microcosm test could provide precise ecological effect assessment of LAS on number of microorganisms because the system showed higher reproducibility and stability than natural take model ecosystem. It was suggested that flask microcosm test was useful ecological effect assessment method which can reflect natural aquatic ecosystem. 10 refs., 4 figs., 2 tabs.

    In order to make clear the difference of the response time between the oxygen sensors with different protection covers, we visualized gas flow inside of sensor covers by means of two experimental methods: One is `Smoke Suspension Method` using liquid paraffin vapor as the smoke. With smoke suspension method, we detected the streamlines inside of the covers. The other is `Color Reaction Method` using the reaction of phenolphthalein and NH3 gas. With color reaction method, we confirmed the streamline inside of the cover and furthermore detected the difference of the response time of each sensor. 3 refs., 7 figs., 1 tab.

    To grasp dynamic cardiac function physiologically and biochemically before, during and after the wheelchair marathon for physically handicapped persons, the safety of athletic sports rapidly diffused for physically handicapped persons and the significance of cooperation among health, medical treatment and welfare are medically evaluated. There were no changes on the echocardiogram. Decrease in left ventricular function, which was observed in the triathlon race, was not recognized. From the results of biochemical test of blood, no damages of cardiac muscle were suggested. The findings of dehydration, which were anticipated in the biochemical test of blood, were not recognized after the race. It was suggested that stricter prevention of atherosclerosis, such as sufficient supply of water, is required for older persons. It is possible that these subjects who have hardly atherosclerosis, if they enter the race after full training and with supplying water, do safely without the bad influence to the heart. 9 refs., 8 figs., 3 tabs.

    The fatigue crack growth tests of WC-Co Cemented Carbides were carried out in a wide range of fatigue crack growth rate covering the threshold stress intensity factor range {Delta} Kth. The effects of the stress ratio, Co volume fraction and the phase transformation of Co on the fatigue crack growth characteristics were investigated on the basis of fracture mechanics and fractography. The crack growth rate was measured using 3-point bending specimens. Crack growth tests were carried out at 10 HZ and the stress ratio R=0.1 and 0.5. The main results obtained are as follows; (1) The Paris rule can be applied between da/dN and{Delta}K and it is shown to be da/dN=C({Delta}K){sup m}. (2) The fractography of the fracture surface, shows that brittle fracture occurs in the Co binder phase at the stress rate R = 0.1 but ductile fracture occurs in the Co binder phase at R= 0.5. (3) The relation of da/dn-{Delta}Keff / E of WC-Co cemented carbides shows the characteristic in the middle of the other metals and the alumina ceramics. (4) The Co binder phase undergoes phase transformation by repeated deformation and so it affects the characteristics delicately. 22 refs., 9 figs., 3 tabs.

    To evaluate the effect of soil improvement by grouting, the test results using a specified type of soil such as standard sand or silica sand and specified chemicals have been conventionally used. However, it is uncertain whether or not the results of such evaluations can be applied to the actual sites. Moreover, the strength of the sand solidified by chemical grouting has only been qualitatively evaluated by its relative density and/or grain size. In this study, the cohesion of sand solidified by chemical grouting was precisely evaluated by a simple method using the hydraulic radius of sand and the tensile strength of pure grout. From the result a quantitative method was proposed for predicting the cohesion of sand solidified by chemical grouting at the actual sites. 4 refs., 9 figs., 5 tabs.

    Because not a very few dam sites have been structured on a soft rock or gravel bed in Japan in recent years, the strength of the ground is too small as a foundation, hence evaluation is required on its seepage failure resistance potential at the dam design stage. Therefore, in order to discuss the evaluation on seepage failure resistance potential with simplified tests, three kinds of tests comprising a needle penetration test, a pick penetration test and a scour test were performed, as well as a uniaxial compression test and an indoor seepage failure test on 32 kinds of soils and soft rocks of Quarternary Pleistocene epoch. The following findings were obtained: high correlation with a correlation coefficient of about 0.8 was seen between the uniaxial compression strength `qu` whose correlation with the limiting hydraulic gradient `icr` being a parameter for the seepage failure resistance potential is relatively high, and the needle penetration gradient `NP` and the pick penetration gradient `PP`; and measurement values useful for the evaluation may be obtained in such a way that the condition of a ground bed requiring detailed discussions on the seepage fault resistance potential as a dam foundation ground may be set as qu {<=} 1, NP {<=} 2 and PP {<=} 4. 13 refs., 15 figs., 4 tabs.

    Performance of various catalysts for hydrogenation of recycle solvent was evaluated for the operation of NEDOL process 1 t/d process supporting unit (PSU). Distillate between 220 and 538{degree}C derived from the liquefaction of Tanito Harum coal was used as recycle solvent. Deactivation behaviors of catalysts were compared using a prediction equation of catalyst life, by which aromatic carbon index (fa) after hydrogenation can be determined from the fa of recycle oil before hydrogenation, reaction temperature, and total hydrogenation time. Total hydrogenation time satisfying the {Delta}fa, 0.05 before and after hydrogenation were 8,000, 4,000, and 2,000 hours for NiMo-based catalysts C, A, and B, respectively. Catalyst C showed the longest life. Used catalysts were also characterized. The catalyst C showed larger mean pore size than those of the others, which resulted in the longer life due to the delay of pore blockage. From measurements by XPS and EPMA, relative atomic concentration of carbon increased remarkably after the use for all of catalysts, which was considered to be due to the adhesion of hydrocarbons. Increase of metal atoms, such as Fe and Cr, was also observed due to the contamination of entrainment residues. Deactivation of catalysts was caused by the adhesion of hydrocarbons, and metallic compounds, such as Fe and Cr. 3 refs., 1 fig., 5 tabs.

    An investigation was given on the relationship between methanol adsorbing behavior of reformed coal surface and oxygen containing functional groups in coal. Akabira bituminous coal was air-oxidized or Yallourn brown coal was decarbonated in oil as a reformation treatment. Both of the treated and untreated coals showed an adsorption heat curve of the Langmuir type. The Akabira coal had its oxygen content and the adsorption heat increased as a result of the air oxidizing reformation treatment. The Yallourn coal had its oxygen content and adsorption heat decreased as a result decarbonation reformation treatment. Oxygen containing functional groups act as strong adsorption sites for methanol, and the maximum adsorption amount depends on oxygen content in the coals. Since the coal surface is non-uniform in terms of energy, methanol is adsorbed first into sites with higher molar adsorption heat, and then into lower sites sequentially. Therefore, distribution of the molar adsorption heat can be derived from the relationship between adsorption amount and adsorption heat by changing methanol adsorption amount. The distribution of molar adsorption heat becomes broader when the oxygen content is high, and narrower when low. 2 refs., 2 figs.

    With an objective to know coal condensation structure which has influence on coal conversion reaction, an attempt was made on quantitative evaluation of hydrogen bonding in coal. Using as test samples the VDC made from Taiheiyo coal swollen by tetralin and vacuum-dried, and its pyrolyzed char, DSC measurement and Fourier transform infrared spectroscopy (FT) were performed. An FT spectrum comparison revealed that the VDC swollen at 220{degree}C has the hydrogen bonding relaxed partly from the original coal. However, since the change is in a huge coal molecular structure restraining space, it has stopped at relaxation of the bonding energy without causing separation as far as free radicals. On the other hand, the DSC curve shows that the VDC has slower endothermic velocity than the original coal. In other words, the difference in heat absorption amounts in both materials is equivalent to the difference of enthalpy ({Delta} H) of both materials, which corresponds to the relaxation of the hydrogen bonding. Therefore, the {Delta} H was related to wavenumber shift of the FT spectra (which corresponds to change in the hydrogen bonding condition). By using this relationship, a method for evaluating hydrogen bonding distribution was proposed from an O-H contracting vibration change that can be measured by using the FT spectra and a thermal change that can be measured by using the DSC. 3 refs., 7 figs.

    Materials having intelligent properties against fracturing were investigated. Synthesis of materials with high toughness, understanding of elementary process of fracturing, and investigation of intelligent structural materials were selected as research themes. For the experiments, relationship was examined between fracture resistance and crack propagation of the highly tough silicon nitride produced by the newly developed texture control method. As a result, it was found that the crack propagation of this material can be detected by abnormally grown grains, and that the resistance against fracturing increases with crack propagation. It was revealed that the present material is a crack diagnostic intelligent material. The crack edge of these liquid phase sintered materials with high toughness is very active. The cracks can be recovered below the sintering temperature. This means that the strength can be recovered by the proper heat treatment on the way of use. The reliability can be secured by the different method from the conventional investigation aiming at high performance. 140 refs., 82 figs., 8 tabs.

For the high temperature heat storage type (utilizing ammonia complexes), the initial research targets are almost attained, as a result of the designs of a chemical heat storage unit having heat storage capacity of 1,000 kWh. For the high temperature heat storage type (utilizing hydration reactions), a 25 Mcal-scale pilot partial test unit is operated, to study applicability of the practical materials and other operation-related themes. For the low temperature heat storage type (utilizing hydration reactions by solute mixing), a pilot system is operated, to attain heat recovery of 75% or more, heat storage density of 30 kcal/kg or more, and output temperature of 7 degrees C. For the low temperature heat storage type (utilizing clathrates), the evaluation tests by a pilot plant produce heat recovery of 93.2% and heat storage density of 32.0 kcal/kg. In addition, the R and D efforts are directed to, e.g., researches on plant simulation techniques and combined systems. (NEDO)

    The water tank test of marine structures or submarine structures uses a wave maker to generate waves. A typical flap wave maker uses the wave making flap penetrating a water surface whose bottom is fixed on a tank bottom through a hinge, and the top is connected with a rod driven by rotating servomotor for reciprocating motion of the flap. However, this driving gear using a rotating servomotor and a bowl- screw has some defects such as noise caused by bowl rotation, backlash due to wear and limited driving speed. A linear motor with less friction mechanisms was thus applied to the driving gear. The performance test result of the prototype driving gear using a linear motor showed the possibility of the linear driven wave maker. The linear driven wave maker could also achieve low noise and simple mechanism. The sufficient durability and applicability of the linear driven wave maker mechanism were confirmed through strength calculation necessary for improving the prototype wave maker. 1 ref., 5 figs., 2 tabs.

Autonomous responsive materials imitate environmental responsibility in the living organism system and have sensing, control and active functions for external stimuli. The materials are highly efficient and environmentally friendly. In biomimetic materials for soft actuators, drastic changes by temperature of elastic modulus of water-swollen hydrogel are used to the motion. In order to molecularly design stimulus-responsible polymer gel, studied are the relation between the micro structure and stimulus responsibility, dynamic correlation between the micro structure and the macro structure, etc. In the biomedical field, new cure and diagnosis using innovative materials are expected, and the application of autonomous responsive materials to the field is studied. For example, using hydrogel responding the temperature and the surface and controlling by temperature the interaction with components of the organism such as protein and cells, drug delivery in the organism is optimized.

    A prototype super-solar bike (SSB) that travels on energy from solar cells was fabricated. This paper describes the results of a performance test and a driving performance simulation. The SSB uses a bicycle as the vehicle, mounted with monocrystalline silicon photovoltaic (PV) cells, a motor, a controller, and an Ni-Zn battery. As a result of the PV cell performance test, the electric energy obtained in a day was 18 Wh, and the solar energy that the SSB can recover in a day was about 236 Wh. As a result of the driving performance simulation, the energy consumed to drive around a circle of 1840 m was 72.5 Wh, and the energy recovered from regenerative brakes used on downward slopes was 5.56 Wh. The total energy consumption was 66.94 Wh, of which about 7.7% can be recovered. However, the power the PV cells can deliver during driving is about 16 W at the sun's altitude in winter, indicating that it is difficult to get the energy required for driving from the PV cells alone. 3 refs., 5 figs., 3 tabs.

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

    Discussed herein are mooring performance requirements of the new types of marine structures now proposed, and characteristic ranges and future expansion potential of the existing mooring systems. The mooring systems studied for floating structures are catenary, single point (multi-leg and single-leg types), fixed structure with fender and tension leg mooring systems. The studied items include extraction of the elements that constitute rigidity of the spring for horizontal mooring, survey on and data collection for each element, determination of element ranges, programs for mooring analysis, assessment of mooring characteristic ranges, and potential development of the characteristic ranges. It is concluded that the existing systems with their current characteristic ranges and future possibility are insufficient for the future marine structures. It is therefore necessary to develop new mooring concepts, instead of expanding the current concepts, in order to meet the mooring performance requirements for the new marine structures. 14 refs., 9 figs., 11 tabs.

Since solar radiation and wind power are complementary to each other in seasons, day and night, and fine and cloudy weather, WISH BOX is useful for standalone power source in non-power areas of developing countries, life spot in disasters, and outdoor leisure. The most small light-weight high-performance AIR303 produced by Southwest Windpower Co., USA is used as wind power generator, and two 50W solar cell panels HSC-5010-S produced by Daido Hokusan Co. is used. Sealed lead storage batteries (12V, 20Ah each) are also connected to cope with load fluctuation. In comparison with conventional portable gasoline engine generators, this environment-friendly generator is featured by fuel-free, no emission of gases, no noises and no fire occurrence, and can also supply stable power with small batteries even in the nighttime and cloudy weather by combining wind power. The generator of 400,000 yen is now in field experiment. 2 refs., 5 figs.

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

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

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

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

    Concerning the effects of carbon dioxide whose level of concentration is on the rise, the short-term effect that works on the amount of exchanged gas and the long-term effect that works on the growth of green plants are studied by use of several kinds of green plants. Changes in the carbon dioxide absorption rate (photosynthetic rate) in saplings in the wake of a rise in carbon dioxide concentration are studied, and it is found that a rise in carbon dioxide concentration results in an increase in the photosynthetic rate and that the rate rises with an increase in the intensity of light. The effect of temperature is stronger when concentration is higher, with the temperature suitable for photosynthesis moving toward the high-temperature side. Growth is investigated of seedlings of Acacia mangium two years after transplantation, and then it is found that seedlings in the 1000ppm carbon dioxide section are greater by 20% in height and by 30% in trunk diameter than those in the 350ppm carbon dioxide section. In addition, the total dry matter weight is heavier by 82%. As for dry matter accumulation, there are noticeable amounts in the branches, trunks, and roots, while there is but a 15% increase in the leaf area. Leaves fall early in the high carbon dioxide environment, and this is supposedly the cause for a slowdown in the rate of the increase of photosynthesis. 6 refs., 7 figs., 2 tabs.

    This paper evaluates influences of stacking of incident angles against the reflecting surface on the resolution. Basic equations for evaluating the influences were deduced. A simple evaluation method has been provided using these equations. The present evaluation method is considered to be useful for acquisition design, processing, and interpretation of data as an indicator. According to the equations introduced in this study, there are some demerits for stacking traces whose incident angles were large. A total reflection region often appears due to the decreased resolution, and the vertical resolution decreases prior to stacking. Occasionally, it is not effective to remove traces having large incident angles from the viewpoint of resolution. In practice, the selection of most suitable trace through trial and error is not easy due to difference in individual regions. An evaluation method must be discussed, by which the optimal trace can be selected automatically during the data processing. 6 refs., 15 figs.

    An investigational study was conducted of the brain function aiming at developing an interface with the same function as humans have. In the study, the most up-to-date information/knowledge and future problems were examined on brain measurement, brain modeling, making a model an element, and the brain function data processing system. As to the brain measurement, the paper took up the multielectrode simultaneous measuring method and the optical multipoint measuring method as an invasive measuring method, and the functional magnetic resonance imaging, near-infrared spectroscopy, magneto-encephalography, and electro-encephalography as a non-invasive measuring method. Relating to the brain modeling, studies were made on senses of sight and smell, the movement control and the learning. As to making a model an element, how to make the modeled function a chip on silicone for example becomes the problem. Reported were two reports on making the sense of sight an element and one report on making the parallel dispersed processing mechanism of brain an element. About the brain function data processing system, three reports were made on the present situation, matters in question, and the future development of the system in the case of catching data processing as a system taking a step ahead from making the model an element. 250 refs., 74 figs., 11 tabs.

    The Ti-Ni alloy, a typical shape memory alloy exhibits the CsCl type crystal structure in the matrix at an elevated temperature, and also exhibits a single crystal structure in the martensite phase at a lower temperature. The matrix phase at a high temperature is likely to be deformed. There is a brother phase which is different in orientation from the matrix phase in the low temperature phase. And the deformation takes place by the movement of their interface. No permanent deformation due to the dislocation takes place. A material which is deformed at a low temperature recovers its shape when it is heated because the material is not permanently deformed. This phenomenon is called the shape memory effect. Ten years have passed since the application research of the shape memory alloy was started. The progress gets slow-down. It becomes seldom that the topics concerning the newly developed products are published on magazines and newspapers. Many of the product developed in the past have been replaced by the other functional goods which were more reliable and less expensive than the shape memory alloy. This paper describes the recent situation of development. 15 refs., 8 figs., 1 tab.

    A study is made for the creation of biopolymeric materials under microgravity. In the synthesis of polymer grains by fast polymerization, the process of polymer grain formation by the oxidation polymerization of pyrrole and long-chain alkyl pyrroles is examined by measuring absorbance, and then it is found that the process is quite different according to the reaction conditions, that is, on the ground or under microgravity. Bacteriorhodopsin, which is a light energy converted protein, is electrodeposited on conductive glass electrodes in an experiment of forming a highly oriented thin film (under microgravity where there is little convection or little difference in specific gravity). Application to electrochemical cells is also performed. A suspension of a substance with biological affinity (chitin, etc.) and an acrylic polymer different in specific gravity from the said substance is filtered, and a thin film of homogeneous structure is obtained. Basic data such as growth rates on the ground and under microgravity are gained by the study of viscous fingering (pseudo 2-dimensional fluid phenomenon) between two planes inserted into a macromolecular water solution. A mixture of silicone oil and macromolecular solution are agitated, and it is found that homogeneous dispersion occurs under microgravity. Crystallization is also experimented of proteins and acidic protease A. 6 refs., 36 figs., 1 tab.

    In order to demonstrate the power transmission using microwave and arrange advantages and problems in the wireless power transmission, field tests of point-to-point power transmission were conducted. Microwave frequency of 2.45 GHz was used, which is assigned as the industrial, scientific and medical frequency. The transmission system is composed of generator, director tube, primary radiator, and transmission antenna. The maximum 5 kW of microwave power can be transmitted by combining a 3 m-diameter parabolic antenna and a magnetron. The receiving system is composed of devices called as RECTENNA (rectifying antenna). A large capacity and high efficiency RECTENNA was developed, by which the maximum 2.5 W of input power per single device can be provided. As a result of the experiments, efficiency at the transmission side was over 70%, and RF-DC efficiency at the receiving side was about 51%. At the open-air test site, however, the total efficiency of only 14.8% could be obtained. 8 refs., 12 figs.

    TV observation is necessary even in a manned submarine boat when making detailed investigation into sea-bottom crevices or narrow places. This paper reports the system configuration, constitutive elements and test results of TV observation equipment of launcher system (an unmanned submersible with maximum use depth of 6500 m) developed with an intention of being mounted on the `Shinkai 6500`. The equipment is accommodated in the launcher while the submarine boat is moving, and launched from and returned to the launcher at the sea bottom, hence its main body was required to be made as small as possible. Therefore, observation devices were limited to one TV camera and two undersea lights, and only a thruster and a driver to drive it were installed. Other related devices were all located on the operation side via tethered cables. As a result of confirming its motion performances, no problems were found in its maneuverability and the camera images, but the acryl window has left some problems including deformation behavior and partial exfoliation. 2 refs., 12 figs., 2 tabs.

    This paper describes the present status of component researches such as combustor endurance of a ramjet engine which can operate with the Mach number of 2.5 to 5 and the reduction of NO{sub x}. The targets of the performance were the Mach number of 2.5 to 5, the combustion temperature of about 1,900 centigrade and the fuel comsumption ratio (at the Mach number of 5) of about 2 kg/hr/kgf. Main research times are the ramjet engine combustion of low pollution, the cooling structure, the combustion control, and the direct test and the free jet test of the ramjet system, of which all are to be finished in 1996. The key point of the success for the propulsion system of Mach number of 5 is the development of the ramjet engine. The premixed lean combustion method was selected to reduce NO{sub X}emission. As the heat resistant composite material, the cooling panel of C/SiC has been experimentally manufactured and studied. As for the combustion control, the combustion efficiency equal to or more than 92% could be obtained by using a model. A V gutter type combustor has been improved and studied.

    Coal liquefaction reaction was carried out in the presence of six kinds of iron sulfide differing in mean grain size as catalyst in order to investigate the liquefaction using a fixed bed reactor. The experimental liquefaction reaction was performed using Wandoan coal, anthracene oil and a specified amount of catalyst in an autoclave in the conditions of 100kg/cm[sup 2] hydrogen, 450[degree]C control temperature and 60mins of duration. The reaction rate increases as the diameter of catalyst particles becomes smaller and the added amount increases. It was found that the generation of C1-C5 hydrocarbon and CO and CO2 is not affected by particle diameter and the added amount and the reaction rate increases with high comsumption of hydrogen. The rate constant kt of THF-soluble fraction generating reaction and the outer surface area Ap of catalyst were obtained from a definition formula. In the range of Ap from 0(no catalyst) to 0.4, kt is 2.0[times]10[sup [minus]2] showing no catalytic effect, but kt increases with the increase of Ap when Ap>8. A liquefaction reaction was performed using a packed bed. In this reaction, 30wt.% slurry of Wandoan coal with hydrogenated anthracene used as solvent was circulated. 3 refs., 3 figs., 4 tabs.

    The paper investigates and reports problems on plastic waste and measures to solve them, and the developmental trend of main biodegradable plastics in the world. A large quantity of plastic waste neither rots nor returns to the nature even if reclaimed. The recycling system has not yet been established due to its low price. Therefore, countries are carrying out regulations on prohibition on the use of foamed polystyrene, compulsory use of degradable plastics, taxation on plastic bottles, etc. Among biodegradable plastics, a type of polyethylene blended with starch is legislated for its use in the U.S., but is met with opposition by environmental organizations because of its plastic powder remaining in the soil. Contrary to this partial degradability, the following are cited as completely degradable plastics: bioplastics based on microorganism, natural polymer based on plants and animals, and biodegradable synthetic polymer. Any of them, however, is still in the stages of research/development and commercialization. 376 refs., 28 figs., 37 tabs.

    The technology trend was surveyed to clarify the themes of smart structural system towards its R and D. The smart structural system is a structural system which incorporates functions of perception, judgment and learning by integrating functions, structures and information, to ensure the structural soundness at real time and control the active-adaptive of shapes. The final goal of it is to make materials and structures similar to organic systems. It has a self-repair function which can detect the generation and propagation of cracks and prevent the destruction positively with conducting self-diagnosis. High performance, high efficiency and energy saving are expected by combining the conversion of design concept into destruction control and the regulation of vibration, noise and shape. Especially, it is effective for the safety of aerospace systems, earthquake disaster measures, and extension of machine life. This report describes the background, purpose, R and D activities in Japan and foreign countries, and basic development themes. In addition, it arranges the needs of various industrial fields systematically, and proposes a concrete concept. Furthermore, the effects expected by the application of smart structural systems and the outline of international technical cooperation are presented. 110 refs., 164 figs., 19 tabs.

    The adsorption of acetaldehyde by porous ceramics impregnated with hydrazinium aluminum sulfate (HAS) is studied. Silicagel, activated alumina, activated clay, and activated carbon are compared, and it is found that silicagel and activated clay are suitable as a substrate for HAS impregnated adsorbent. The adsorption mechanism of acetaldehyde by the adsorbent is believed to be one in which acetaldehyde reacts with hydrazinium and yields acetaldazine. The adsorption capacity of the adsorbent at low acetaldehyde concentration of 0.1 ppm was as large as 1.36 mol/kg. This adsorption capacity at 0.1 ppm acetaldehyde concentration is remarkably larger than that of conventional activated carbon. Hydrazinium decomposes easily in the air because it is a strong reducing agent and reacts with oxygen or carbon dioxide. But hydrazinium impregnated on porous ceramics with HAS becomes more stable and maintains reactivity with acetaldehyde for longer than six months. An adsorbent made of porous ceramics impregnated with HAS is useful as a deodorant for acetaldehyde. 8 refs., 6 figs., 6 tabs.

    My efforts towards at the development of aeroengines since the end of the war are described. The J3-7 engine propelled the T1 trainer plane, and was installed as booster aboard the P2J antisubmarine patrol aircraft. It was the first jet engine that Japan produced after the end of the war, and had been in use until quite recently. I took part in the construction of a prototype of the JR100 series designed to serve as VTOL (vertical take-off and landing) aircraft lift engines, and in the test thereof. As the shift from turbojet to turbofan proceeded, I participated in the development of the FJR710 engine under the guidance of National Aerospace Laboratory, and the product was installed aboard an experimental STOL (short take-off and landing) aircraft Asuka. I next joined a Defense Agency initiative for a reheat turbofan to replace the J3 aboard trainer plane, and the result was the low bypass ratio/high output F3 engine. In 1989, Ministry of International Trade and Industry decided for a large-scale project of developing an engine for a next-generation supersonic transport, and the HYPR (Super/Hypersonic Transport Propulsion System) project was started. The project was participated in by manufacturers from overseas, which were GE, P and W, RR, and SNECMA. The foreign corporations worked on an equal footing with the Japanese parties, and collaboration between the participants was smooth, with each party endeavoring in the field they were good at. The project will be concluded as scheduled in fiscal 1998. (NEDO)

    This paper describes R and D of the variable cycle turbofan engine in HYPR (Super/Hyper-Sonic Transport Propulsion System) project. HYPR has developed the combined cycle engine (CCE) composed of a turbofan engine (0-3 in Mach number) and a ramjet engine (2.5-5). The turbofan engine adopts the concept of a variable cycle engine (VCE) to satisfy such exclusive requirements as low noises (low exhaust velocity) at takeoff and landing and high specific impulse (high exhaust velocity) at high-Mach number acceleration. The HYPR turbojet engine is a 2-axis turbofan engine composed of 2- stage fan, 5-stage high-pressure compressor, 1-stage annular type combustor, 1-stage high-pressure turbine, and 1-stage low-pressure turbine. As variable mechanism, a low-pressure turbine variable nozzle, rear variable bypass nozzle, 2-D variable exhaust nozzle, and high-pressure compressor variable static vane are integrated. The high-altitude performance test showed a favorable mechanical soundness during cruising. (NEDO)

    Basic research of biological measures for which the accumulation of basic findings is mandatory and the applied research of chemical and physical measures that are higher in feasibility are conducted for the establishment of measures to counter freshwater red tides. In the basic research, natural enemies, algaecidal microbes, conjugation inhibiting substances, and allelopathy are studied, but none of them is found feasible at the current stage. In the basic research, however, factors are discovered that inhibit the multiplication of Peridinium bipes or perish the same. In the applied research, chemical algaecidal methods, UV-aided algaecidal methods, and various red-tide constituent collection methods are studied. Collection methods are compared, and it is concluded that a method of Toray Industries, Inc., efficiently collects red-tide constituents. In this method, red-tide constituents are screened by and condensed on a cloth filter provided on the internal wall of a drum, and are dehydrated and then transferred. The applied research further involves the prediction of red tide outbreak and the raising of fish on a food containing substances extracted from red tides, and it is suggested that these are feasible. 18 refs., 15 figs., 3 tabs.

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

    This is the report No. 98 issued by the Inorganic Material Research Institute. An intelligent material is a substance and/or material which responds intelligently to environmental conditions and exhibits functions. One of the features of amorphous materials including amorphous glass is a large freedom in chemical composition. These materials maintain order in short distance, but have as a whole the turbulent and specific atom orientation. Therefore, high tolerability in selecting the composition, and diverse synthesizing methods are available. A wide range of utilization may be conceived, such as introduction of the state of electrons having different valences in a structure, and the diverse chemical combinations. Patterns of existence of polyhedrons having different orientations, and how they are connected correlate closely with an external environment. Intelligent materials have high freedom against change in the external environment and are suitable to exhibit intelligent functions. Setting heat and light as the external conditions, attempts have been made on search and creation of intelligent materials based on state change induced by interactions between the two factors. Fundamental studies have been made on synthesis of different environment responding glasses and films, and on factors and phenomena for exhibition of the intelligence. 62 refs., 91 figs., 8 tabs.

    Some sulfides containing silver show high ion mobility based on movability of silver, whose application is expected. Studies have been carried out centrally on synthesis of new compounds of ternary silver sulfides by elucidating the relationship among their compositions, structures and properties by means of crystal chemical studies mainly on their phase relationship. A few new compounds have been synthesized, such as the ones having the argyrodite family compound structure including transition metals. The synthesizing process takes a kind of turbulent liquid state structure at elevated temperatures because of movability of silver, but silver is fixed at low temperatures in different sites between skeleton structures made by other atoms. These studies on phase transfer, structures, and silver movability have been based on X-ray diffraction, infrared and Raman spectroscopic measurements, NMR, measurements of electric and thermal characteristics. For the studies related to compositions and structures of ternary metal sulfides which take compound crystalline structure, a structure analyzing method based on multi-dimensional hyperspatial groups was used. This paper reports the summary of the studies in seven chapters, and dwells on the remaining problems and future prospects. 158 refs., 114 figs., 65 tabs.

    Availability of viewing landmarks including ancient castles affects largely the image of a local area. Large buildings planned to be built in a city area rearrangement programs may hinder viewing the landmarks from around those buildings. A method was developed to evaluate quantitatively the effects of obstructions on the views by using a three-dimensional analysis based on a 3-D model with an intention to minimize these observation hindrances. This paper describes the examples of discussions given on the building construction plan in the center of the city of Kumamoto placing the Kumamoto Castle as the core of the viewpoints. The planned K and S buildings were investigated of their individual effects varying their shapes, locations and angles but not varying the building volumetric figures. As a result of discussing composite effects from these two buildings considered simultaneously, the relative locations and building angles for both buildings that can minimize the observation hindrance were proposed. This method could handle the scenery arrangements more flexibly than the conventional fixed regulations including the indiscriminate height regulation. 5 refs., 16 figs.

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

    The research and development were conducted jointly with Europe of an environmental harmony type high efficient catalyst which enables clean combustion and NOx removal in polluted gas in combustion flue gas, etc. In the research and development of NOx removal catalyst such as zeolite base, reformation of mostly mordenite was done by ion exchange, ion implantation, skeleton element substitution, etc. A possibility was found out of applying the membrane formation method except ion implantation as reforming means. In the R and D of the complex oxide base NOx removal catalyst, it was found that the catalyst carrying copper and silver on silica and layer clay compound under optimum conditions shows peculiarly high activity, and there is little decrease in the activity, but rather increase in it even under vapor existence. An evaluation was made of NO resolution of direct resolution element carrying noble metal electrolyte on solid electrolyte, finding out that the highest NO selectivity is shown with Pd as electrolyte and at a baking temperature of about 1300degC. Development of high- and low-temperature catalysts was also made. 417 refs., 286 figs., 63 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)

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

    This 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)

    Out of the developments of high efficient boilers which have been continued since fiscal 1993, the paper reported the result of the development conducted in fiscal 1996. The oxygen combustion (the oxygen enrichment combustion including 100% oxygen combustion) decreases the amount of flue gas and reduces heat loss of the flue gas, and is also effective as NOx reduction measures. The experiment was conducted using testing furnace. The boiler efficiency rapidly increased with the increasing concentration of oxygen enrichment. In the pure oxygen combustion, the overall boiler efficiency of a 106% level (low heating value standard) is expected. Since the boiler wet flue gas is decreased, the NOx emission is reduced. The boiler can raise the combustion temperature with no fear of NOx and can be reduced in size. CO2 decreases in proportion to the energy saving effect. The development of a condensation flue gas heat exchanger is aimed at recovering heat down to the low temperature. Prediction of heat transfer in the steam condensation region becomes possible, and the size reduction can be expected. Dew point corrosion resistant materials were also selected. As to the high speed combustion control, a simple type using micro-processor was developed. Obtained were high speed, compactness, electric power saving, and high controllability. 14 refs., 306 figs., 88 tabs.

    To further enhance energy efficiency by improving on the gas turbine system, it is necessary, first of all, to develop superhigh-temperature materials to allow the system to operate at higher temperatures. Described in this report are studies on the application of MGC (melt-growth composite) materials which retain strength and plastic deformation capability even at high temperatures. Various compositions are explored for improvement on fracture toughness and thermal shock resistance. The Al{sub 2}O{sub 3}/YAG system is investigated for the study of relations between microstructural control and fracture toughness. Literature on the development of nanocomposites is surveyed, and a preliminary experiment is discussed for improvement on purity by zone melting crystallization. In a study for an advanced manufacture of larger crystals, technologies of crystal growth condition setting and optimization, quality stabilization, productivity improvement, and crystal size enlargement are taken up. Casting and machining technologies are studied to enable crystals to assume complicated shapes. For the purpose of elucidating the mechanism of the occurrence of properties proper to high temperatures, a study is made on the evaluation of mechanical and physical properties and on the mechanism and control of crystal growth. Also studied are systems (gas turbine cycle, combustor, etc.) to which MGC materials may be applied. (NEDO)

    For the promotion of research exchanges on global environmental preservation with developing countries, Ms. Malee Santikunaporn, lecturer of Faculty of Engineering, Thammasat University, Bankok, Thailand was invited. Desulfurization/denitrification facilities, which are being widely spread in developed countries, have marked effects, but high prices are an obstacle to the spread in developing countries. To make them spread in developing countries, it is needed to develop the technology which is low in price and meets the actual state in developing countries. As a technology with high viability, a system to simultaneously remove SOx and NOx was cited in which Cu is used as catalyst and adsorbent and into which the catalyst regeneration process is integrated. Considering it, technical exchanges on Cu-SiO{sub 2} catalyst as the basic theme were made during September 26 - December 23, 1999. Through visits on and exchanges with Tokyo Institute of Technology, ICEET, University of Kyoto, etc., understanding was deepened about how each country is tackling environmental problems. The theme 'Oxidative sorption of SO2 by Cu-SiO{sub 2} catalyst: characteristics of catalyst' could deepen knowledge/information of the developmental research as a system for simultaneous removal of SOx/NOx. The data obtained indicated great practicality of Cu-SiO{sub 2}. (NEDO)

    The R and D program is implemented for permanent magnet, as part of the project aimed at commercialization of a 10 MWh-class high-temperature superconducting magnetic bearing type power storage system. A speed of rotation of 28,570 rpm is attained by using an iron intermediate ring for a Pr permanent magnet rotator and reinforcing the rotator with a plastic hoop reinforced with carbon fibers three-fold (CFPR hoop). The speed is increased to 31,300 rpm by interlacing carbon fibers also in the radial direction and replacing iron for the intermediate ring by titanium. The highest speed of rotation of 33,506 rpm is realized by the rotator of permanent magnet of sintered Nd. The magnetic circuit of stronger, more smooth magnetic field needs the permanent magnet of less uneven magnetic flux. The magnet is of a monoaxially anisotropic rare-earth metal, with four-fold magnetic ring bodies having fan-shaped small pieces arranged on each ring. Uneven magnetic flux occurs at the joint between these small pieces. The one-body-ring magnet of radially anisotropic, sintered Nd is developed, and incorporated in the repulsion type magnetic circuit, to reduce unevenness of the magnetic flux. (NEDO)

    In the prior paper, a loop-type osmotic beat pipe was investigated on the heat transport rate from the upper position to the lower. The beat transport rate of this osmotic heat pipe, however, was very small because of small driving force for the solution circulation. Therefore, the osmotic heat pipe with the higher driving force is devised. The larger driving force is produced by a two-phase flow taking place in the solution riser. For the sake of that, a vopor-liquid separator is installed at the top of the apparatus and a heated section is attached as some distance below the separator, so that buoyant force caused by density difference between the fluids in the solution riser and downcomer increases. This osmotic heat pipe with the two-phase solution circulation loop indicates the higher heat transport rate than that of the osmotic heat pipe shown in the prior paper. (author)

    Proportional, integral and derivative (PID) controls are used for a steering system and a main engine control unit installed in a vessel. Among them, this paper describes effectiveness of a PID gain tuning method using a limit cycle by means of relay control which is safer and simpler than conventional limit sensitivity methods. The present method was applied to an actual marine control system to conduct an actual vessel experiment. As a result of applying the method to a bow azimuth control system using a rudder, a new azimuth setting was set with an overshoot of 1.6 degrees in a ten-degree azimuth changing experiment. With respect to direction maintaining steering performance, the present method was capable of controlling the direction at a speed loss to about 80% of the ship`s autopilot. As a result of applying the method to a bow azimuth control system using a bow thruster, direction maintaining and changing control was realized in a low speed range in which rudder effect is lost. As a result of applying it to a main engine governor system and performing control of main engine rotation speed, it was found possible to derive control gains in a safe state without applying an excessive load to the main engine both under load and no load conditions. 14 refs., 8 figs., 11 tabs.

    The materials and products constituting the urban spectacles are generally defined as 'Spectacle materials'. And, a human being, space and time are grasped as factors of the spectacle, their mutual relationships are grasped as three systems, and the spectacle materials are also defined as media for these systems. A human being is affected mentally by spacial features. The system comprising a human being and space is a field of design, which is thought to represent the sensitive face of a human being. A human being-time system where a human being is present in flow of time is a field of environment, which is thought to express a physiological side of a human being. At last, time-space system expresses the features of spaces resisting to time and the space changing with time, which is thought to be a field of structure. Among them, there are some features required for the spectacle materials. The development of urban spectacle materials making a contribution to city life, such as a human being can live peacefully, feel convenient, be comfortable and healthy, be friendly for a human being and the earth, and so forth, is expected. 16 refs., 17 figs., 1 tab.

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

    Basic studies are conducted for the collection of methane from the methane hydrate that exists at levels deeper than 500m in the sea. The relationship between the hydrate generation mechanism and water cluster structure is examined by use of mass spectronomy. It is found that, among the stable liquid phase clusters, the (H2O)21H{sup +} cluster is the most stable. Stable hydrate clusters are in presence in quantities, and participate in the formation of hydrate crystal nuclei. For the elucidation of the nucleus formation mechanism, a kinetic simulation is conducted of molecules in the cohesion system consisting of water and methane molecules. Water molecules that array near methane molecules at the normal pressure is disarrayed under a higher pressure for rearray into a hydrate structure. Hydrate formation and breakdown in the three-phase equilibrium state of H2O, CH4, and CO2 at a low temperature and high pressure are tested, which discloses that supercooling is required for formation, that it is possible to extract CH4 first for replacement by guest molecule CO2 since CO2 is stabler than CH4 at a lower pressure or higher temperature, and that formation is easier to take place when the grain diameter is larger at the formation point since larger grain diameters result in a higher formation temperature. 3 figs.

    Explanation is made of the bioprocess which aims at treating the atmospheric CO2. As a result of investigation by the Electric Power Research Institute (EPRI), it was judged that the direct CO2 removal from the flue gas of power station is costwise disadvantageous and that the biological method by CO2 fixation is economical. The following are projects supported by the EPRI: The seaweed fossilization of CO2 is a medium depth sea mechanism of having seaweeds absorb carbon and making it remain residually in the deepsea even after the plants die. Study is being made of oceanic seaweed cultivation field development, non-calcareous seaweed cultivation and spore collection. The cost is advantageously low. The cultivation of seaweeds and halophilous plants utilizes their photosynthesis to collect CO2. There are examples of studying the possibility of cultivating those plants through comparison with the land trees. The growth ratio of halophilous plants is being also studied together with the possibility that the carbon remains as a residue. The whiting is a phenomenon in which biodecomposed subsea matter becomes CaCO3. Covered with CaCO3, the ssaweeds are deposited. Investigation is being made on the seaweed morphology and condition for the occurrence of whiting. 1 ref., 2 figs., 1 tab.

    AS for C60 group, the molecule itself is moderately stable, and moreover responds to the various reactions. For the metals too, it makes the ionic compounds upto -6 valence with the alkaline and alkaline earth metals, and it is thought to have an appropriate affinity with other metals. In addition, its size is in a nano scale. These properties have a possibility, that it can create an interesting composite in a nano scale by combining it as a raw material with other raw materials. C60 group is a negative element on the periodic law table, and can be said as the transition elements, of which valence can vary from -1 to -6. As same as the conventional positive transition metals existed so far have opened the vast field of inorganic chemistry, the fullerene is anticipated to develop a great field also in inorganic chemistry region from now on. In this paper, a process that the science of fullerene, after the discovery of its synthesis and separation, have been developing quite rapidly, is described, and then the basic trend of its progress is outlined from the materials science view points. 43 refs., 9 figs.

    With respect to concept of resolution in seismic exploration using the reflection method, detailed considerations were given on processes of forming the resolution as a result of arranging observation points at vibration transmitting and receiving points. In the discussion, numerical experiments were carried out, in which the scattering stacking process is applied in a model having one scatterer existing in homogeneous media. The experiments investigated an imaging formation process of the scatterer when arrangement of the vibration transmitting and receiving points were changed from a coarse condition to a dense condition while the number of transmitting and receiving points is being increased. Resolution is created if waveforms having finite frequencies are used as input, and the imaging is performed by utilizing the limited number of vibration receiving and transmitting points. If the concept of equi-travel plane is used under these conditions, the equi-travel planes perform negation with each other, and it was indicated that visual resolution is expressed by how good the negating effect is. It was discovered that such concept of the resolution is quite ambiguous in terms of engineerings. 2 refs., 17 figs.

    With an objective to develop an airborne electromagnetic survey method for greater depths achievable of exploration, a discussion was given on an exploration method of a type in which a transmitting device is placed on the ground to receive signals in an atmosphere. A prototype exploration apparatus is mounted with a fluxgate magnetometer, an attitude meter, a GPS, and a battery. This exploration apparatus is suspended on a 30 meter long rope from a helicopter to perform the exploration. Two flight tests on this apparatus were carried out in the Unzen area, Nagasaki Prefecture and the Motomiya area, Wakayama Prefecture. The ground source was extended to a distance of 1.5 km, and a current of about 20 A was flown with a quiescent wave having four-second cycles. The helicopter flew nearly horizontally at a ground speed of about 50 km, a flight altitude of 450 m above sea level, and a terrain clearances of 100 to 400 m. The obtained data had variations in correspondence with changes in roll and pitch angles, whereas the variation of about 5000 nT was reduced to about 1000 nT as a result of correction. It was not possible, however, to correct completely the variation with short cycles, requiring further discussions on frequency characteristics of the magnetometer. 6 figs., 1 tab.

    It is intended to recover more effectively thermal energy currently discharged from marine vessels into air. This paper describes a diesel engine combined power generation system in which medium-order waste heat energy from a diesel engine for power generation in a marine vessel is recovered and utilized to operate a Rankine cycle system (using the waste gas as the high temperature source and sea water as the low temperature source), thus the thermal energy is recovered as a motive force. Two kinds of fluorocarbons and steam were discussed as a working fluid. Due to fluorocarbons making the whole system ultra-high in pressure, and from a viewpoint of high-temperature thermal stability, the temperature was remained at levels from 100 to 200 degC, and a single-stage expansion cycle was used. With the use of steam, a two-stage reheating cycle was employed, by which the temperature is raised fully up to 300 degC and effective head of fluid was taken largely. Ceramic paint was used as a means to prevent sulfur oxide corrosion when the system is used down to the dew point, and its effectiveness was verified. Motive force recovered by combining the steam two-stage reheating cycle and the ceramic painted heat collector was calculated, whereas electric power output of about 45 kW was obtained from a main generator with 450 PS. The derived thermal efficiency was about 26%. 2 refs., 24 figs., 2 tabs.

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

    Discussing the rotor blades of the torsion arc blade type (TABT) wind turbine, difference in windmilling characteristics was determined between elliptic blades and rectangular blades by theoretical analysis and model experiment. Experimental generation of power was carried out using a test wind turbine in the natural wind. First, elliptic blades were bent into arcs and fixed to shaft. The action force was determined calculating the blade area and the wind velocity vertical thereto. Furthermore, the force in the direction to turn the rotor was determined with the effect of the part behind the blade taken into account. The rotation-curbing air resistance in the flank direction that a rotor experiences was subtracted to determine the torque generated. A formula was derived for the elliptic blade. Second, a formula was derived in the same way for the case of rectangular blades. In conclusion, in the case of 6-blade wind turbine, the rate of responsibility for wind turbine rotation of the part behind the blade was approximately 50% of the part in front of the blade. Shape coefficients were introduced into the theory, which resulted in values agreeing well with values obtained from experiments. Elliptic blades yielded more power than rectangular blades at the same wind velocity. High in durability, the TABT wind turbine is expected to be put into practical use as a compact auxiliary power generating device. 2 refs., 14 figs.

    To reduce fossil fuel consumption and CO2 emission, this article introduces an actually constructed natural energy autonomous house. It has a solar collector on the south roof for hot water supply and a sky radiator on the north roof for cooling water supply. The sky radiator uses radiation cooling phenomena into the space by electromagnetic wave through the window of atmosphere. This house also has an insulated tank with a capacity of 31 m{sup 3} in its underground. In the long-term heat storage mode, the heat is collected through the solar radiation during the period from summer to spring and is stored in the underground water tank, to use it for heating and hot water supply in winter. The heat can be recovered from the garbage waste incinerator. A gas fired auxiliary boiler is used for the shortage. In the long-term heat regeneration mode, the heat is regenerated through the sky radiator during the period from spring to summer and is stored in the underground water tank, to use it for cooling in summer. For the shortage, the water is cooled using a heat pump operated by the midnight power. The insulating performance is improved by using the pair glass in windows and the glass wool in the walls. Rain water is collected in a tank with a capacity of 2 m{sup 3}, to use it for toilet water. Annual energy and water saving is equivalent to 600,000 yen. 10 refs., 10 figs., 2 tabs.

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

    Study was made of an ice-on-coil heat storage tank for power load levelling. Prior to the prediction of performance of the system as a whole, the performance of the heat storage tank itself needs to be predicted. A brine (35.9% water solution of ethylene glycol) cooled by a refrigerating machine was poured from the upper end of the piping in the heat storage tank (consisting of 19 spiral pipes or coils arranged in parallel in the vertical direction) for the collection of ice around the coils. Ice grew thicker with the passage of time but there was no remarkable decrease in the transfer of heat because there was an increase in the area of contact between ice and water, and the brine exit temperature remained constant over a prolonged period of time. There was a close agreement between experiment results and theoretical conclusions throughout the heat accumulation process, including changes with time in the thickness of ice on the coils, all pointing to the appropriateness of this analytical effort. To melt the ice, water was poured into the tank top at a predetermined rate. Water chilly at 2-4{degree}C was recovered at the tank bottom, stable in the amount produced. As for the use of spiral pipes for making ice, the laminar heat transfer rate in such pipes are supposed to be more than two times higher than that in straight pipes, and this was quite effective in accelerating heat transfer. 7 refs., 11 figs.

    Mechanized work of high fluidity concrete is possible because of its self-compactability (SC), however, it requires both high fluidity and non-separability of materials as basic conditions, and yield strengths over a certain value. Unlike Newtonian fluid, the SC is thus restrained. For improving the reliability of the SC of high fluidity concrete, the predicting method of the SC was proposed on the basis of a self-compacting mechanism model. It was assumed that the SC is dependent on a surface resistance of formworks, internal friction angle of concrete, and resistance due to steel bars. The estimation equation of the frictional resistance of formworks was derived from formwork material properties and coarse aggregate bulk concentrations. The equation of the internal friction angle of high fluidity concrete was also derived from coarse aggregate bulk concentrations. The validity of this model was confirmed by verifying the SC with a model formwork and real structures. Prediction of the SC by this method before placing can improve work reliability. 4 refs., 24 figs., 15 tabs.

    An on-site test is conducted of devices for reducing in a short time the volume of jellyfish that flow into power plants. There are three methods to reduce the volume of jellyfish by separating water from them, which are heating, pressing, and chemical. The chemical treatment is not an object of this test because it is expected that the volume reduction rate by this method will be too low. For the achievement of a reduction rate of 80%, the two methods, physical and crushing, are compared at the laboratory level. It is found that the crushing method is superior because it can dispose of jellyfish in a shorter time. Using this method, the crushed jellyfish is separated into drain and bubbles, the latter containing jellyfish fragments. An on-site test is conducted using a general-purpose crusher. The relationship between the filter diameter (1-5mm) and the separation rate is investigated, and it is found that separation proceeds more rapidly when the filter diameter is smaller. It is found that the addition of a certain chemical accelerates the separation. COD (chemical oxygen demand) is 300-490mg/l in the drain, and BOD (biological oxygen demand) 400-500mg/l, with COD having increased by approximately 20%. A study is scheduled to be conducted using an experimental apparatus. (NEDO)

    Very fine structure control technique for amorphous and nanostructured metallic materials was reviewed to exceed the marginal performance of small metallic member materials. In Japan, high strength alloys and anticorrosion alloys are currently developed as an amorphous structure control technique, and ultra fine powder production and nano-compaction molding are studied for nanostructured materials. Fabrication of amorphous alloy wire materials and metal glass in USA are also introduced. Fabrication of metallic nanocrystals deposited within gas phase in Germany are attracting attention. The strength and abrasion resistance are remarkably enhanced by making nanostructured crystals and dispersing them. It may be most suitable to utilize amorphous and nanostructured metallic materials for earth-friendly materials having anticorrosion, and catalyst and biomaterial affinities, and also for magnetic materials. It is important for controlling micro-structures to clarify the formation mechanism of structures. For their processing techniques, the diversity and possibility are suggested, as to the condensation and solidification of gaseous and liquid phase metals, the molding and processing of very fine solid phase alloys, and the manufacturing members by heat treatment. 324 refs., 109 figs., 21 tabs.

    This research project aims to establish a technique for crystal growth using pressure as a principal control parameter, and combining it with a microgravity condition, to develop a novel process material fabrication. Since the solubility of materials depends on pressure, it is possible to control a supersaturated condition for crystal growth by changing pressure. The growth condition can be controlled precisely, which is not possible by conventional methods that vary temperature and other factors. On the other hand, because a concentration diffusing field is formed autonomically around crystals in association with their growth, density convection is generated under gravity as a result of difference in the concentrations, making the growth conditions severely complex and uncontrollable. Ideal crystal growth condition control may be possible if the pressure control is performed under micro-gravity by which generation of the density convection can be suppressed. Realization has been achieved on in-situ observation by using high-magnification microscope which uses a diamond anvil cell, development of a hydraulic type optic pressure cell, and a high- speed crystal growing technology by means of pressure control utilizing the cell. New findings were also obtained on effects of pressure on crystal forms, and the pressure induced solid phase transfer mechanism. 67 refs., 49 figs., 3 tabs.

    For effective promotion of creative and innovative technologies, and cooperative development of industrial technologies in Japan, hearing survey was made to collect various opinions on industrial technologies from learned people. It is necessary to overthrow the industrial policy of following-the-preceding-U.S. type. Discrimination by production technologies can hardly be expected, and a service sector shows poorer productivity. Manufacturing industry is ill-balanced among competition, cooperation and conflicts. Trade policy is strongly linked to innovation. On the government`s role and policy, it is necessary to discuss science and technology distinctively, and the policy is demanded to shift from a need type to a seed type. Basic research, industry-university cooperation, patent system and market expansion are important for innovation. The government`s initiative is essential for innovation and standardization. For better social and economic systems, loans and orders for promising red-ridden firms, and reforming convoy-transports style are necessary. Private firms require the clear direction of the policy, and clear intellectual property and standardization policies.

    For further improvement of iron system materials, supermetals with ultimate characteristics were researched. Since their strength and toughness have been improved with grain refinement by thermomechanical treatment, improvement of single-phase steel is nearly completed, and the study on ultra-fine multi-phase steel is indispensable. Bulky materials are also restrained from grain refinement because of the capability of existing processing facilities. Making a breakthrough in such restraint requires a challenge to high-speed rolling, repeated shear deformation and ultra-high strain rate process beyond conventional technologies. Further improvement of microstructure and dynamic characteristics requires other energies such as magnetism as well as mechanical energy. {gamma}-{alpha} phase transition important for structure control of steel materials is dependent on magnetism. The study on structure control and characteristics improvement under ferromagnetic field is essential in the future. Material improvement such as reduction of impurities and circulating elements, environmental measures, and mechanical alloying remain as issues to be studied. 224 refs., 176 figs., 18 tabs.

    For the development of an airborne electromagnetic prospecting method capable of deeper exploration, a basic study was made about a system wherein a transmitter (source) is positioned on the ground and the receiving is done in the sky. Even in case of this airborne electromagnetic method, the TDEM method is supposedly advantageous over others as in case of groundborne exploration. In the study, the transient response of an airborne vertical magnetic field to a horizontal layered structure was calculated. The current source was 2000m long with a capacity of 30A. The one-layer structure was a 10 Ohm m semi-infinite ground, and the two-layer structure had a 100 Ohm m structure just under the one-layer structure. The result of the calculation suggests that, in the absence of a layer of extremely low resistivity, observation of an approximately 1 second long transient response aboard a helicopter flying at approximately 50km/h will enable an approximately 1000m deep exploration. Problems to affect airborne observation, such as swinging, natural magnetic field fluctuation, and artificially produced noises were investigated by use of a magnetometer suspended from a helicopter in flight. 2 refs., 6 figs.

    Analyses were performed recently on results of observations having been carried out by the U.S. National Oceanic and Atmospheric Administration (NOAA) and the Japanese Meteorological Agency by using wave observation buoys. Wave observation database with high reliability has become publicized in the same format as the conventional wave generation frequency data. In order to obtain rational base for a method to set hazardous sea areas, the present study has attempted to express as a function of the average wave cycle a maximum value of significant wave heights which can be generated based on these data. What were derived include observations by the NOAA over large areas, such as Alaskan coasts, Mexico Bay and Five Great Lakes, the results of discussions by the Meteorological Agency on data including wave observations at five locations in neighboring waters in Japan, and the relationship between the maximum value of significant wave heights that can be generated and the average cycle. Deriving the standard deviation per unit wave height by computing short time estimation from the above data, and deriving combination of the average cycle with angles of encounter can present the design hydrographic conditions (hazardous hydrographic conditions). The future would require not only investigations and discussions from the viewpoint of the maximum value that can occur, but also from the viewpoint of determination of limitations of vessel operations. 5 refs., 5 figs.

    Development has been made on a towed and self-propulsive, remotely controlled submarine vehicle for sea bottom survey. This paper reports the results of simulational calculations and water tank experiments for its performance verification. In the towing mode test, sufficient submarine depth change was found possible even with a little weight movement as a result of having selected an adequate towing point. Highly accurate depth control was possible in the towing mode by using a controller that uses linear quadratic with integral(LQI)control in combination with gain scheduling. In the towing mode, the controller using the LQI control was capable of maintaining well a constant depth against fluctuation in the towing speed of 30%. In the self-propulsive mode, depth control using thrusters was found capable of making prompt motions, effective and excellent for the purpose. In the self-propulsive mode, the controller using the LQI control exhibited superior depth and direction control capability, and was capable of stable transfer at switching the towing mode to and from the self-propulsive mode. The calculation result showed good agreement with the experimental result. 12 refs., 24 figs., 1 tab.

    A study is made for the elucidation of the effect of microgravity on biofunctions. The protoplast of shiitake is exposed to microgravity and then cultured, and a significant difference occurs. The rate of colony formation by cell fusion in the test sector is found to be two times higher than that in the control sector. When swimming ciliates which are unicellular are suddenly exposed to microgravity, their swimming speeds changed differently according to the direction of swimming. When a mouse subjected to acupuncture for three days is exposed to microgravity, its water metabolism and excretory function are enhanced. A mouse treated with Chinese medicine reacts in the similar way. The change due to microgravity in the amount of acetylcholine in the hypothalamus is found characteristically time dependent. Mice infected with lethal herpes viruses just after exposure to microgravity die at a rate in proportion to the number of exposures and to the amount of viruses given. The migration speed of chemical stripes in case of a gel-base BZ (Belousov-Zhabotinsky) reaction under microgravity is equal to that on the ground. The trigger wave migration speed in case of a water solution-base BZ reaction under microgravity is reduced to approximately 80% of the speed on the ground. 12 refs., 31 figs., 3 tabs.

    This paper describes in detail the experimental and theoretical results of a new type of Stirling engine with a pendulum-type displacer (PDSE) that is suspended by a hinge shaft and swings in a displacer space. The main features of PDSE are its simplicity, ease of outside gas sealing, and lower mechanical friction than that of the conventional-type Stirling engine. However, gas leakage inside the displacer is larger than that of the conventional type. The power required to induce a pendulum-type displacer motion, which consists of flow loss powers of multiple fin gas passage and regenerator wire mesh, is analyzed using a simple equation. It has been clarified that the calculated theoretical power output agreed well with the experimental power output. It has also been clarified that the measured Nusselt number of the regenerator agreed with that of a previous study. It is hoped that PDSE can be employed to utilize natural heat energy sources in the future. 8 refs., 10 figs., 2 tabs.

    Liquefaction is applied to various biomass wastes and unused biomass to study characteristics of the liquefaction in each case. The paper described the system of the conversion and use of biomass into energy, conducted the positioning of the liquefaction, and outlined a history of the liquefaction chemistry and the study. To obtain basic data of characteristics of the liquefaction of various biomass raw materials, the liquefaction was conducted changing operational factors for the purpose of clarifying the product distribution of oil and by-products and oil properties. A comprehensive consideration was made of the liquefaction based on basic data and literature reports on the liquefaction of various biomass. From the above-mentioned studies, it was concluded that the energy can be recovered in a form of oil by applying the liquefaction to various biomass materials. A series of the study clarified effects of various operational factors on characteristics of the liquefaction as well as effects of classification of biomass materials and composition of the materials on characteristics of the liquefaction. 141 refs., 78 figs., 56 tabs.

    Research and development is actively conducted on machining technologies using plasma in various fields, with studies energetically pursued on etching techniques or those of forming a thin film by the use of high frequency and microwave plasma. The EBEP system jointly developed by Kawasaki Heavy Industries Ltd. and Institute of Physical and Chemical Research is a plasma source for forming a high density plasma by implanting into a plasma chamber from the outside a high-current electron beam accelerated to an energy of approximately 60 to 100eV where the collision cross-section of gas ionization is maximized. The characteristics of the system are such as (1) it enables electron energy distribution to be controlled from outside by varying acceleration voltage, (2) it excels in the controllability of ion energy and (3) it allows to form a steady high-density plasma in a nonmagnetic field. This paper presents the generating principle of EBEP, its plasma characteristics, etching technique using EBEP, thin film forming technique by EBEP-CVD method, and multipurpose apparatus for research and development. 6 refs., 7 figs., 1 tab.

    A basic study was made on CO2 solidification by haptophycean algae as phytoplankton. Haptophycean algae have functions of not only carbon dioxide assimilation but also of CO2 calcification. By using Gephyrocapsa oceanica and Pleurochrysis haptonemofera as haptophycean algae, optosynthesis velocity and calcification velocity were measured by a carbon isotope method, the CO2 solidification capacity of both algae was compared, CO2 partial pressure changes in the culture process and changes in the amount of inorganic and organic carbon by alga culture in high concentration CO2 were measured. As a result, it was revealed that carbon solidification increased in alga culture in high CO2 concentration. It was also revealed that acceleration of calcification velocity required high photosynthesis velocity. There is a possibility that CO2 may be solidified by culturing haptophycean algae. The solidification ability of Pleurochrysis haptonemofera is about the same as that of chlorella algae. It was calculated that an area of 2.8 [times] 10[sup 4] ha. was required for 7.4 [times] 10[sup 9] kg CO2 emitted from a power plant. 16 figs., 1 tab.

    Creation of new functional organic materials for the medical application has been investigated under the microgravity. Facilities of the Japan Microgravity Center were used for this study. For the high-speed synthesis of uniform polymer particles under the microgravity condition for ten seconds, appropriately good results were obtained in the oxidation polymerization of pyrroles. For the synthesis of organic conductive thin films by the electrolytic polymerization, the resistance of electrolyte became larger in the microgravity field. It was required to set conditions so as to enhance the effects of microgravity environment. For the orientation control and thin film formation of proteins, the bacteriorhodopsin was examined. It was found that the microgravity improved the quality of electrocoatings. When the surface tension and viscosity of coating liquid were appropriately controlled under the microgravity, thin films were able to be prepared by utilizing a change from 1g to {mu}g. When the high viscosity fluid is placed in the artificial two-dimensional space composing of two parallel plates, and the low viscosity fluid, such as air, is injected into the above, the interface grows in the finger shaped pattern, namely, viscous fingering. The influence of gravity on this phenomenon was also investigated. 11 refs., 45 figs., 5 tabs.

    In order to find the higher critical strength, toughness and corrosion resistance of Al system materials than those obtained by conventional methods, crystal grain control was studied in a finer-grain region. The above characteristics of Al materials obtained by conventional technologies such as alloy element addition and heat treatment controlling crystal grains of several tens {mu}m are approaching critical values, resulting in poor characteristics for the latest needs. It has been confirmed experimentally in fundamental studies using small specimens that fine crystal grains of several {mu}m can remarkably enhance the above characteristics. Technology for creating mesoscopic structure-controlled materials was thus studied. In particular, creation of ultra-fine advanced Al alloy bulk materials by cryogenic processing method was selectively studied. The developmental approach and its issue were thus revealed for creating mesoscopic crystal structure by recovery and recrystallization of a highly distorted state obtained by cryogenic processing. 102 refs., 80 figs., 8 tabs.

    Development of nenroactive materials to improve neuronal defects is one of the most important subjects in Japan that will soon become a aging society. In this project, basic research for neuroactive molecule was performed to develop technology for neuronal regeneration, regulation of synaptic activity and interface between artificial surface and living neurons. A novel neurite promoting factor was discovered and its cDNA was cloned. Mutagenesis in vitro showed that a functional region of this factor located in a polypeptide of less than 50 aminoacids. Using neuronal culture, synapse formation was found to depend on two modes of activities and long-lasting synaptic potentiation was demonstrated to depend on a macromolecules released from pre- or postsynaptic neurons. To regulate nervous activities, photoactivated caged-peptide was developed and confirmed to change in affinity to its receptor. Neurons were cultured on substrates paterned by microlithography.

    The mechanism of rifled tube for the DNB improvement was studied to reflect the superior characteristics to the practical design and to get the quantitative data. Now, the application of the rifled tube to evaporator tube is studied. The pressure drop of two-phase flow could be derived by using the pressure drop of single phase flow and an emperical formula was derived from the experimental results. In addition, the two-phase DNB predicting method of rifled tube which provides a flow disturbing effect based on the knowledge of two-phase flow of smooth tube. This predicting formula enabled the prediction of DNB in both areas where the DNB improving effect was recognized and the DNB improving effect was not recognized. The behavior of DNB characteristics of rifled tube which had been fragmentary was analyzed by simulating experiments using freon. As a result, it was found that the area showing the large DNB improving effect transferred to higher mass velocity side and the area showing few DNB improving effect spread by the increase of pressure and heat flux. 9 refs., 14 figs., 1 tab.

    The studies on combinations of high-performance compression heat pump and chemical heat accumulation systems are conducted to construct the optimum systems for air conditioning/hot water supply for large-sized buildings and local districts, and also for industrial processes. For partial optimization of super heat pump (SPH) accumulation system, the SPH operational mode is changed to find the optimum conditions. As a result, it is found that system efficiency is the highest, and hence the power cost is the lowest, when the system is continuously operated night and day, followed by 2-night/1-day mode and night alone mode, in this order, for office building air conditioning, district air conditioning, and hot water supply. The effects of combination of SHP and chemical heat accumulation systems incorporated in an industrial process for heating are estimated. The results indicate that power load leveling effect is not 100% but 92%, even when the heat required for the daytime operation is totally supplied from the chemical accumulation system. The skeleton of the super heat pump accumulation system simulator is finalized, and the elementary system modules are developed, to allow simulation of general flows. (NEDO)

    A proposal was given on an equivalent crack tip opening displacement (CTOD) concept which relates quantitatively fracture performance of a structural member with the result of a three-point bending CTOD test via the Weibull stress based on a local approach. The equivalent CTOD is defined as a CTOD in which a three-point CTOD test piece and a structural member provide the same Weibull stress. Experimental and analytical discussions were performed on X80 steel welded joints. Effectiveness of the equivalent CTOD concept was verified from the fact that the fracture performance in welded joints with a large width estimated from the result of the three-point bending CTOD test using the equivalent CTOD concept showed good correspondence with the fracture performance obtained in the experiments. On the other hand, the result of estimation using the conventional CTOD concept is considerably smaller than measurements. As an application of the equivalent CTOD concept, a new determination procedure was introduced on required fracture tenacity to ensure deformation performance required on structural elements. The required CTOD value shows a trend that the smaller the ratio of yield stress of the welded metals to that in the base material, the greater the required CTOD grows. 16 refs., 19 figs., 3 tabs.

    High-temperature properties of glass melts, e.g., density, volume expansion coefficient, surface tension, viscosity, specific heat, thermal and electrical conductivity, redox equilibrium and gas solubility, are basic factors that must be considered in high quality glass melting technology and computer simulation of the glass tank furnace. The structure of the glass melts is also important for understanding these properties. This R and D program is aimed at proposing the international standards for the methods of measuring these high-temperature properties of the melts.

    The microcosm has its etymology in the `small outer space`, which is a system that groups or clusters of solid substances are cultivated in a certain container. The system has been prepared to elucidate the ecology and interactions of microorganisms and their structures. This paper describes analysis and assessment on the system based on the results of past studies thereof with an intention to utilize it as a model aquatic ecosystem for a test to assess influence on the ecosystem. It is necessary that, in the case of evaluating the influence on chemical substances, an elucidation be made on a concentration at which clusters of living organisms are not affected even if such chemical substances exist in the environment for a long period of time. In the case of an exotic microorganism, an elucidation should also be given on a concentration that does not affect the environment as seen from the survivability of the microorganism in the environment and its interactions with other microorganisms. A large number of examples of experiments shows that a microcosm test contains material cycle and interactions in multiple kinds of living organism systems, and has high reproducibility and stability. A discussion should now be required that the above test method be positioned as an ecosystem assessment method. 19 refs., 3 figs.

    Autonomic neuropathy function immediately after a change to upright posture has been evaluated by applying transient response function of the system to the blood regulation system. The impulse response function was determined from the change in heart rate before postural change to the upright posture, and was compared with the transient change immediately after a change to the upright posture. The time series of R-R interval of electrocardiogram was used as the time series of the change in heart rate. To determine the impulse response function, an autoregressive model was applied to the R-R interval time series. The impulse response function at the steady state is a transient reaction at the impulse stimulation added to the blood regulation system. The R-R interval decreases rapidly by the autonomic neuropathy reaction in which the blood is rapidly transferred into the legs immediately after a change to upright posture. There is a close correlation between the initial temporary decrease in R-R interval and the impulse response function derived from the change in heart rate immediately after a change to the upright posture. Accordingly, the blood regulation and autonomic neuropathy functions can be evaluated by the impulse response function without actual standing test and load of tested persons. 9 refs., 3 figs., 1 tab.

    In general, it is most efficient and economical to install photovoltaic (PV) modules with proper slope. There are room spaces on the wall except ground or roof. The PV modules were installed on the vertical wall, to consider the compensative method for this weak point. When modules were installed vertically, there is an advantage that reflecting solar light as well as incident solar light can be utilized compared with the installation with slope. The PV modules were installed on the roof of building with inclination of 90{degree} facing to south using the roof material as a reflecting material (S90), and with inclination of 15{degree} facing to south (S15), to compare their output. The output ratio, S90/S15 was 0.42. When it was very fine, this value increased to 0.60. When using plated steel plate as the reflecting material, this value increased to 0.74, which provided 10 to 30% larger output than the roof material. From these results, about 50% of module output of S15 can be expected for S90. If receiving larger reflection, there would only a slight difference in the module output between S15 and S90. 3 figs., 1 tab.

    In this paper, to evaluate the hydrogen production cost per unit volume, system optimization of solar hydrogen energy system is discussed. Based on the simulation of the I-V characteristics of amorphous Si (a-Si) photovoltaic array, the working point between the array and hydrogen generator was determined. The cost ratio of each design point was calculated. The optimum design points were 500 W/m{sup 2} for the single crystal Si system, and 600 W/m{sup 2} for the a-Si system. When the rating capacity of design point was constant, almost constant cost ratio was obtained independent of the type of photovoltaic cells. It was found that the photovoltaic cells can be fabricated in about 15% lower cost at maximum. It was also found that the optimum design point sifts to the lower insolation site due to reduction of the photovoltaic cell cost. Since the annual hydrogen generation quantity does not depend on the type of photovoltaic cells under the constant rating capacity of design point, hydrogen can be produced in lower cost by using photovoltaic cell of lower cost. 5 refs., 10 figs., 5 tabs.

    The titled {mu}-oxo-metal(III) phthalocyanine dimers were prepared and investigated their polymorphs through X-ray diffraction analysis. It was found that {mu}-oxo-aluminum phthalocyanine dimer and {mu}-oxo-gallium phthalocyanine dimer have several polymorphs, but one of the target compounds, that is {mu}-oxo-indium phthalocyanine dimer, could not be synthesized because chloroindium phthalocyanine was easily hydrolyzed through acid-pasting treatment procedure to give metal-free phthalocyanine. The characterization of these compounds by the several chemical analytical methods was satisfied for the target molecules and the FD-Mass analysis distinguished clearly between the hydroxymetal phthalocyanine and the corresponding phthalocyanine dimer. We also studied their photoconductive properties on the bilayer photoreceptor consisted of the above phthalocyanine dimer as the charge generating material. It was found that the specific polymorphs of {mu}-oxo-metal(III) phthalocyanine dimers have good photoconductive properties: the APL-II(the II type of {mu}-oxo-Al(III) phthalocyanine dimer discussed in this article) has a good spectral response of the photosensitivity in the shorter wavelength, and the GPL-G (the G type of {mu}-oxo-Ga(III) phthalocyanine dimer discussed in this article) has a fairly high photosensitivity in the wavelength region of laser diode light wavelength, compared with the common phthalocyanine photoreceptors. 14 refs., 9 figs., 3 tabs.

    As characterization of artificial cracks formed underground by using the water pressure fracturing method, experiments have been carried out to detect relationship of pressurization and S-wave propagation time with the polarizing direction dependence. Openings are created when pressure in the vicinity of the artificial cracks increases greater than reopening pressure of micro cracks. Elastic wave velocity decreases in this region because of water in the opened micro cracks. Anisotropy is created in the S-wave propagation velocity due to influence from anisotropic reopening region when the artificial cracks are pressurized, and is separated into two components which polarize orthogonally with each other (micro splitting). Field experiments conducted at the Higashi-hachimantai field were analyzed by using wavelet transform. It was possible to detect the S-wave arrival time at high accuracy, and the arrival of an orthogonally polarized wave was observed in 0.03 to 0.11 ms after the arrival of the S-wave. Possibility was indicated on separation of the two components in the orthogonally polarized wave of the S-wave if the micro splitting is used. If this mechanism is elucidated, it may be possible to extract information on cracking systems (direction of micro crack orientation and crack density). 8 refs., 10 figs.

    An earthquake damage of a shield-driven flannel occurred during the 1985 Michoacan earthquake in the central part of Mexico City. The damages were mainly originated from tunnel axial deformations, such as tension and torsion. In order to improve seismic safety of urban tunnels due to tunnel axial deformations during earthquakes, a seismic immolation structure, in which an isolation layer is formed between a tuner lining and its surrounding soil, is presented. This paper presents a simplified method to evaluate the isolation effect of the seismic isolation structure using axisymmetric finite element models. Through parametric studies using the models, the isolation effect is evaluated in terms of the axial and torsional strain seduction ratios. Furthermore, material properties to be needed as the isolation layer is determined from static stability analyses as well as dynamic analyses. As a result, the importance of high Poisson`s ratio of the layer material is proposed. 9 refs., 15 figs., 2 tabs.

    Concerning a slope stability evaluation model, a `fractal feature quantity` was introduced for accuracy improvement in the evaluation of potential landslide locations. The slope stability evaluation model is peculiar in that it only discriminates between the presence and absence of potential collapse without ranking the imminency of possible danger. As one of the predisposing elements, the fractal dimension was developed into an image, defined as the `fractal feature quantity,` and introduced into the model. The accuracy of evaluation of potential landslide locations was verified using landslide training data, and it was found that the use of `fractal feature quantity` improved on the accuracy of discrimination between the collapsed and not-collapsed, and it became possible to mark out potential landslide locations. The effect of this model is higher than that of the normalized vegetation index derived calculated from the satellite-transmitted data. Next, a differential image was composed reflecting the difference between a case with a `fractal feature quantity` and a case without a `fractal feature quantity`, from which an evaluation method would develop capable of predicting whether or not there exists the danger of landslide. 17 refs., 8 figs., 6 tabs.

    As part of validation processes of in vitro toxicity assays for the risk assessment of environmental hazards, we applied an in vitro toxicity test using two human cell lines, neuroblastoma NB-1 cells and glioblastoma U-87 MG cells, to the assessment of organochlorine compounds detected in the water environment. The in vitro toxicity assay using NB-1 cells was calibrated by testing reference chemicals proposed by MEIC (Multicenter Evaluation of In Vitro Cytotoxicity), an international program for the validation of in vitro cytotoxicity assays. Beforehand, an assay using cells in frozen stock without subcultivation was examined by comparing IC50 values with the ordinary assay using subcultured cells. IC50 values for MEIC reference chemicals from the former assay showed good correlation with those from the latter assay, suggesting that the assay using cells in frozen stock can be used at least for the assessment of basal cytotoxicity. IC50 values for ten organochlorine compounds frequently detected in the sediment samples from contaminated rivers, p-chloroaniline, 3,4-dichloroaniline, p-dichlorobenzene, o-dichlorobenzene, Tris (2-chloroethyl)-phosphate, 2,5-dichlorophenol, 2,5-dichloroanisol, Triclosan and Triclocarban, were obtained with the in vitro assays and compared with their LD50 values in rats. No significant correlation, however, was seen between the IC50 and LD50 values, indicating that further improvement of in vitro toxicity assays is necessary for the application to the risk assessment of environmental hazards. 7 refs., 4 figs., 1 tab.

    In the field test project for the photovoltaic power generation for public facilities, operational data were collected/analyzed on facilities at 158 sites installed from FY 1994 to FY 1997. As a result, the following were found out: Average values of the global radiation on an inclined surface, equivalent array operation time, equivalent system operation time, system operation time, inverter performance efficiency, inverter load factor, array power coefficient, and system power coefficient are 3.51 kWh/m{sup 2}/D, 2.72 h/D, 2.47 h/D, 10.3 h/D, 0.91, 0.30, 0.77 and 0.70, respectively. No deterioration with age was recognized in the 4-year operation data. As to the maintenance, the item, 'there are a lot of failures in the photovoltaic power system,' was 2% in rate. As to the inspection, times are mostly once a month. The annual maintenance cost was widely between about 360 yen/kW and about 30,000 yen/kW. Supposing annual expenses to be a total of capital expense, direct expense, and general administrative expense, the power generation cost dropped from approximately 240 yen/kWh in FY 1994 to 100 yen/kWh in FY 1997.

    This paper depicts desirable pictures of more effective global land utilization required in association with expansion in human activities that aim at sustained development of the human race, and discusses landuse planning. Targeted discussion items include the followings: Frameworks for discussing land utilization planning on a global scale; desirable patterns of land utilization; and application of global land suitability evaluation for forest conservation and reforestation to global landuse planning. An investigation was made on the following items: Evaluation on suitability of forest conservation and reforestration as seen from capability of fixing and storing carbon dioxide; storable amount of cumulative carbons seen by suitabilities; and a trade-off relation between carbon dioxide fixable amount as a result of reforestration and population accommodating capacity seen from food production. Utilizing the result of evaluating the forest conservation and reforestration suitability, the paper shows possibilities and limits of forests to fix carbon dioxide. It further explains that the carbon dioxide fixable amount using reforestration is in a trade-off relation with food producible amount through competition with latent agricultural land utilization. 4 refs., 5 figs.

    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.

    In order to develop the evaluation methods for reappearing corrosion characteristics of coated steel sheets in a short time, acid rain composition and artificial acid rain composition for the accelerated test were studied, and the cyclic corrosion tests were conducted. The literature survey shows that the main ionic species present in acid rain are Ca{sup 2+}, Mg{sup 2+}, Na{sup +}, K{sup +}, NH{sub 4}{sup +}, SO{sub 4}{sup 2-}, NO{sub 3}{sup -}, and Cl{sup -}, of which the acid rain components are SO{sub 4}{sup 2-} and NO{sub 3}{sup -}, their equivalent ratio (NO{sub 3}{sup -}/ SO{sub 4}{sup 2-}) in the Far Eastern area being 0.2 to 0.3. Therefore, the solution specified by ASTM 1141 is diluted 30 times with water to prepare the base solution for the accelerated tests, where its acidity is adjusted with a mixed acid of NO{sub 3}{sup -}/ SO{sub 4}{sup 2-} = 0.2 to 0.3 (pH: 3.0 to 4.0). Two sets of preliminary cyclic corrosion tests were conducted, one involving acid rain spraying, drying and humidification in this order, and the other acid rain spraying, humidification and drying. Analysis of the test data indicates that difference between these test cycles in corrosion rate is within a deviation range caused by different testing tools. Therefore, the former condition is adopted as the basis for the accelerated tests, because of its smaller deviation caused by different testing tools. (NEDO)

    An SSRT test and a CBB test were carried out on carbon steel and heat treated materials applied with bead welding of single pass simulating fillet welding in oxygen-enriched high-temperature water environment, and the stress-corrosion cracking susceptibility was evaluated. Highly hard welding heat affected zones with Vickers hardness of more than 400 have grain boundary stress-corrosion cracking susceptibility. However, a structure whose high hardness has been realized by tempering treatment has no grain boundary stress-corrosion cracking susceptibility. In the SSRT test, stress-corrosion cracking fractured face rate rises with rising test temperature, resulting in stress-corrosion cracking susceptibility shown even at lower hardness. On the other hand in the CBB test, a large number of relatively shallow cracks are generated down to low hardness at temperatures below 190 degC, while the number of cracking occurrence decreases as the temperature rises. However, deep cracks increase. In the CBB test on tempered heat treatment materials, the fact that stress-corrosion cracking can occur in test pieces with Vickers hardness of 165, which is nearly the same as that for the base material, proves that no lower limit hardness exists practically in occurrence of stress-corrosion cracking in carbon steel. 13 refs., 12 figs., 2 tabs.

    Evaluation was made on the surface layer of high tensile stainless steel which had undergone ion implantation treatment. First, the microhardness evaluation method of ultra-thin surface layer was attempted. Fully-annealed S25C steel was used as standard specimen. Study was made on the loading method of the pressure loading for the load dependency of hardness, and statistical distribution of indentator depth for the dispersion in hardness. As a result, load increasing speed and time which had small load dependency were verified. By conducting statistical treatment of repeated measurement data, it was made clear that the accuracy would increase. By the newly established evaluation method, surface hardness of ion-implanted high tensile strength Martensite type stainless steel was measured. Increase in hardness was confirmed for ion-implanted materials, and materials which had undergone ion-implantation and heat treatment (annealing). In either case, maximum hardness was obtained when the indentator load was 0.05 N. The amount of improvement was significant in the ultra-thin surface layer for ion-implanted materials, and deeper in depth in the case of ion-implantation heat treatment process. This conforms with the implantation ion diffusion behavior. 12 refs., 12 figs., 1 tab.

    The bond quality of a solder-bonded copper laminated plate was modeled into rigid contact (rc) and slip contact (sc) to calculate the velocity dispersion of lamb waves. The velocity dispersion of laser generated lamb waves was measured, and the bond quality or the thickness of a solder layer was evaluated by non-contact. In the model whose bond surface is rc, the velocity dispersion of lamb waves can be calculated under conditions where the stress and displacement in an interface are continuous. In the model whose bond surface is sc, it can be calculated under conditions where an interface slips freely. Weak bond indicates the velocity dispersion between rc and sc. In this model, the velocity dispersion can also be calculated by a change in the thickness of a solder layer and used for quantitative evaluation of a bond interface. A three-layer solder bond manufactured for trial could be evaluated from the velocity dispersion of laser lamb waves. At the room temperature, the change in bond quality near the solder melting point of bond laminate that was judged as rc was investigated. When the solidus temperature is exceeded, the amplitude of lamb waves and the velocity dispersion changed largely. The amplitude of lamb waves increases as the liquid phase ratio increases. The bond quality near the solder melting point can be evaluated using lamb waves. 9 refs., 10 figs., 2 tabs.

    We developed a new laser surface acoustic wave (SAW) system and applied this to estimate the mechanical properties of the wear-resistant Ni-P layer electroplated on a stainless steel. The velocity dispersions of Rayleigh wave of the as -plated and heat-treated Ni-P layer were obtained by the one point time domain signal processing. The Ni-P layers with excellent wear resistance produced by the heated treatment higher than 725K were found to show higher Rayleigh velocities than that of the substrate steel, while the Ni-P layer with poor wear resistance showed lower velocities. Young`s moduli of the Ni-P layer, estimated so as the computed velocity dispersion agreed with the measured one, increased with the increase of wear resistance. 10 refs., 9 figs., 2 tabs.

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

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

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

    This paper describes effects of allelochemicals secreted by Myriophyllum spicatum on growth of blue-green algae. In order to propose an effective growth inhibitory method of blue-green algae with less impact on the ecosystem, biological interaction (allelopathy) between large aquatic plants and algae was investigated. Pyrogallic acid, gallic acid, catechin and ellagic acid secreted by M. spicatum provided growth inhibitory effects of blue-green algae (Microcyctis aeruginosa), individually. Complex interaction and allelopathic contribution of these four polyphenols were evaluated. By comparing the actual effects with the expected values, synergetic growth inhibitory effects were recognized by adding four polyphenols at the same time. Furthermore, growth inhibitory effects were evaluated for actual culture solution of M. spicatum and simulated culture solution made by four polyphenols. As a result, it was found that these four polyphenols relate to allelopathy of M. spicatum. 25 refs., 6 figs., 4 tabs.

    A proposal is made on the evaluation method for design input ground motions, which is based on the examples of earthquake ground motions evaluated using fault models and is supported by the concept for future design earthquake ground motions. The features of this evaluation method are to designate earthquakes to be considered and evaluate the ground motions in the applicable site employing fault models. Waveform synthesis method is used where uneven sliding on the fault surface in the earthquake site is taken into consideration. A method of evaluating ground motions in the site using fault models is employed in lieu of the conventional method which is used for aseismatic design input ground motions for high rise buildings, and an example is given quoting the case of reclaimed land and alluvial ground at Yokohama City, Japan. The studied earthquakes are hypothetical recurrence of 1923 southern Kanto earthquake and hypothetical earthquake in Tokai region, and the evaluation of the ground motions is made by waveform synthesis method using fault models for which records of medium scale ground motions obtained near those sites are used. The maximum ground accelerations of about 330Gal and 115Gal, and the maximum velocities of about 40cm/s and 20cm/s are obtained for the hypothetical southern Kanto earthquake and the hypothetical earthquake in Tokai region, respectively. 32 refs., 16 figs., 3 tabs.

    A method of measuring/evaluating a mental and physical state by means of physiological information developed by a project was compiled into a 'guide book', as was a method of evaluating adaptability to the environment or products; and, this manual was prepared for the purpose of improving the adaptability of human beings to products by making use of the guide book widely in the field of industrial manufacturing.

    Recycle of materials is expected to reduce the environmental burden caused by their production process. However, recycle may also lead to the accumulation of impurities and other effects which usually lower social utility of the use of materials. To evaluate these effects totally, we have constructed analytical models of recycle system and proposed formulas to estimate CO2 emission, impurity concentration, etc. in the recycle system. In this report, by using our models and formulas, we evaluated the influences of change in recovery ratio and life expectancy of steel products on the environmental burden as CO2 emission and the quality of materials as accumulation of Cu element. The result shows that change in each parameter has different influences and that appropriate combination of the parameters can lead to reduction in CO2 emission and improvement of material qualities simultaneously. 8 refs., 12 figs.

    In a vehicle collision accident analysis, the behavior of the vehicle immediately before and after the occurrence of the accident is presumed from the situation of the accident site such as the tire marks remaining at the site, the condition of the body deformation, the last position of the vehicle`s stoppage, etc.. The vehicle collision accident analysis is called also the accident reconstruction, and various analytic models have been proposed, but many of them are analytic models to presume, prior to the collision, the situation after it, and models which analyze the pre-collision situation from the situation after it are not many. In this study, an accident analytic model has been prepared which can reconstruct the vehicle`s speed prior to the collision and its behavior after it only from the stoppage position of the vehicle after the collision and the position of the vehicle at the point of collision by adapting the law of conservation of momentum and the Gim`s tire model. In other words, each analytic equation of the momentum analytic model immediately after the collision, the two-dimensional vehicle movement, the dynamic model, and the verification model of the speed immediately before the collision have been roughly explained and by comparing 5 examples of the experimental results of actual vehicles` collisions with the analytic calculation results of the above model, the validity of the above model has been verified. 4 refs., 6 figs., 1 tab.

    Noise problems caused by two-phase flows in tubes connected to air-cooled heat exchangers have become more serious. since the level of air conditioner fan noise has decreased. In particular, when a slug flow occurs. the noise level greatly increases. In this study, an air-water two-phase flow was used to create a slug flow through a capillary tube in order to investigate the mechanism of the noise. We also investigated the relationship between the gas bubble state and the pressure pulsation by changing the void fraction. The results show that the pressure pulsation level, which is proportional to the noise level, is determined by the magnitude and the density of the impact pressure pulsation caused by the expansion of the gas at the end of the capillary tube. 11 refs., 14 figs.

    Considering integrated hull and piping design in shipbuilding industry as a good example for concurrent engineering (CE), discussions were given on a computer aided method to perform integrated hull and piping design smoothly. When CE aiding by means of a computer is considered, it is important to discuss a method for information management not only for `utilization of product models`, but also for `maintaining consistency between items of product information` and `concurrent utilization and production of product information` in concurrent designs. For the CE aided information management, utilization and production of the product information is effective if restrictive relationship between items of product information, and design functions are made clear. Definitions were given on the restrictive relationship between items of product information and `restrictive relationship information` that has `decision/provisional decision`, `date and time`, `designer` and `design functions`. Furthermore, `comprehensive relationship between items of product information` that can be produced from the restrictive relationship information was defined as a `restrictive network`. Utilizing the restrictive relationship between items of product information for CE aiding is effective. 9 refs., 14 figs.

    It is known in estimating vibration characteristics of a ship that fluid range affects largely a structure. A parameter calculation was performed on node vibration in the vertical direction of a rotating elliptic body such as a ship to investigate the effect of an arranging method of the measurement points upon the result of the analysis. As a result, it is thought that equivalent interval arrangement of 21 measurement points would be sufficient in a lower order side mode of vibrations with less than four nodes. An analysis of calculations performed by arranging measurement points in experimental measurement points revealed that analysis accuracy would not increase even if the number of measurement points is increased if it is done so without considering rotation vector. An experiment was carried out with the number of measurement points increased to verify the above fact, with which the analysis was verified correct. Therefore, as has been forecasted in the previous report, the cause for the analysis accuracy deterioration in a high order mode may be estimated as the effect of the rotation vector. However, since it is not the situation that an analysis considering the rotation vector has been conducted, it cannot be concluded yet that the effect of the rotation vector is the sole cause. 4 refs., 14 figs., 7 tabs.

    Risk assessed structural positions in a pressurized fuselage of a transport-type aircraft applied with damage tolerance design are taken up as the subject of discussion. A small number of data obtained from inspections on the positions was used to discuss the Bayesian reliability analysis that can estimate also a proper non-periodic inspection schedule, while estimating proper values for uncertain factors. As a result, time period of generating fatigue cracks was determined according to procedure of detailed visual inspections. The analysis method was found capable of estimating values that are thought reasonable and the proper inspection schedule using these values, in spite of placing the fatigue crack progress expression in a very simple form and estimating both factors as the uncertain factors. Thus, the present analysis method was verified of its effectiveness. This study has discussed at the same time the structural positions, modeling of fatigue cracks generated and develop in the positions, conditions for destruction, damage factors, and capability of the inspection from different viewpoints. This reliability analysis method is thought effective also on such other structures as offshore structures. 18 refs., 8 figs., 1 tab.

    This paper presents the fiscal 2000 results of R and D of underground storage technology for carbon dioxide. As basic experiments, a measurement apparatus was manufactured for simulating the pressure and temperature conditions in aquifers to measure the rate at which CO{sub 2} is dissolved in water and the reactivity between CO{sub 2} and rocks, with the basic performance verified. Methods were investigated and classified that monitor environmental impact and safety. For the purpose of anticipating the long-term behaviors of CO{sub 2} sequestered underground, a simulator was developed, extracting, from investigation of the literature, natural phenomena required for the anticipation. As the system studies, examination was conducted for analysis of the energy balance of the underground storage technology, rational design (safety and economy) of an entire system ranging from source to storage point, investigation from social and economic perspectives, and estimation of the effect of suppressing global warming. In the injection experiment, Minami-Nagaoka natural gas field was selected as a prospective experiment site from the characteristics of the cap rock and aquifer. One injection well was drilled to a depth of 1,230 m, with investigations performed such as physical well-logging and core sampling. Existing data were utilized in the simulation study of CO{sub 2} behavior underground during the injection period. The information of the basic geophysical survey/exploratory well by the Japan National Oil Corporation was collected and compiled, with the preliminary geological study undertaken in the areas described.

    This paper describes analysis and enhancement of nitrogen-fixing gene of rice root bacteria, such as Klebsiella oxytoca, Azospirillum lipoferumn and Sphingomonas paucimobilis, for realizing energy saving through conservation of nitrogenous fertilizers. For K. oxytoca, modified strain R-16 was developed, which can fix nitrogen effectively even in the presence of NH4{sup +}. Nitrogen-fixing ability of A. lipoferumn depends on the activity control by the modification of nitrogen-fixing enzyme as well as on the adjustment of transcription level by the transcription activating gene, nifA. The control gene relating to the above was analyzed by making clones. As a result, a modified strain TAl without the control by NH4{sup +} was developed. The R-16 and TAl strains were inoculated into rice sterile-cultured without nitrogen. Consequently, inoculated strains were settled in the root, which resulted in the increased vegetation weight of plant to two times heavier than that without inoculation. 9 refs.

    Studies are made to define the working mechanism of semiconductor photocatalysts such as TiO2 and to establish designing guidelines for improving on their activity and functions. TiO2 in the air actively produces oxygen seeds for the oxidation and removal of NOx, etc. It is desired that a catalyst have a specific surface area large enough to retain the product of its action. To meet the need, a thin-film photocatalyst which is an aggregate of TiO2 crystals is produced by burning a film of a sol/gel system of reaction doped with macromolecules. This product has a larger specific surface area and is higher in pollutant-removing performance, and may be put into practical use. In another experiment, metal-carrying particles TiO2 suspended in water are employed for the reduction of CO2. Though the main product of catalysts carrying Pt or Pd is methane, a photocatalyst carrying RuO2 produces acetic acid mainly and loses less activity with the passage of time. A hybrid photocatalyst is composed of an organic pigment and inorganic semiconductor, synthesized through a covalent bond between a sililated-surface thin TiO2 film and porphyrin. It is confirmed that the newly developed process brings about an increase in electron migration efficiency. 3 figs.

    This paper describes an influence of additional elements on the high temperature deformation behavior of Nb-base solid solution alloys. Highly concentrated solid solution single crystals of Nb-Ta and Nb-Mo alloys were prepared. Compression test and strain rate sudden change test were conducted in the vacuum at temperatures ranging from 77 to 1773 K, to determine the strain rate sensitivity index. Yield stress of the Nb-Ta alloy was similar to that of Nb alloy at temperatures over 0.3{times}T{sub M}, where T{sub M} is fusing point of Nb. While, the yield stress increased with increasing the impurity oxygen concentration at temperatures below 0.3{times}T{sub M}. The yield stress became much higher than that of Nb alloy. The strain rate sensitivity index showed positive values in the whole temperature range. On the other hand, the yield stress of Nb-Mo alloy was higher than that of Nb alloy in the whole temperature range, and increased with increasing the Mo concentration. The strain rate sensitivity index showed negative values at the temperature range from 0.3{times}T{sub M} to 0.4{times}T{sub M}. It was found that serration occurred often for Nb-40Mo alloys. 1 ref., 4 figs., 1 tab.

    This paper describes the fundamental experiments for creating property-gradient polymer electrolyte for rechargeable lithium batteries. The rechargeable lithium battery is composed of an anodic composite agent section with high ion conductivity, a separator equivalent section with high mechanical strength (high bridging degree), and a section surpressing the precipitation of metal lithium by contacting with it. The continuous property-gradient polymer electrolyte was tried to be synthesized by means of the plasma polymerization method. As a result, plasma polymerization electrolyte with high ion conductivity could be prepared from the liquid phase by using a monomer with low vapor pressure. Porous material simulating the anodic composite agent was impregnated by the monomer, which was plasma-polymerized. As a result, it was found that the bridging degree decreased from the surface towards the inside of the plasma-polymerized porous material. In addition, polymer was prepared using fluorine-base monomer. Thus, LiF thin film could be prepared through the reaction between the polymer and metal lithium. 3 figs.

    This paper describes the research and development of power generation system by means of chemical-looping combustion. For this system, fuel flows in a reduction reactor and air flows in an oxidation reactor. These two flows are separated. As a result, recovery of CO2 without energy consumption, drastic improvement of power generation efficiency, and suppression of NOx emission are expected. To realize the above, two promising candidates, NiCoO2/YSZ and NiO2/NiAl2O4, have been found as recycle solid particles between the both reactors. These have excellent oxidation/reduction cycle characteristics. By these particles as well as the existing particle, NiO/YSZ, practical application of the chemical-looping combustion is realized. Besides LNG, coal and hydrogen were considered as fuels. When using coal or hydrogen, it was found that temperature of the reduction reactor should be increased the same as that of the oxidation reactor. This is a different point from a case using LNG as a fuel. 5 refs., 2 figs.

    The aim of the project is to develop a new logging-while-drilling device which utilize a pulsed neutron generator (PNG) in order to protect operation personnel and environment from unintentional nuclear radioactivity. Instead of using AmBe nuclear reaction which is commonly used in a wireline and LWD logging device, PNG utilize Deuterium-Tritium fission under electrical control. This eliminates neutron bursts on rig floor, and in the situation when the tool was stacked and its electrical supply was stopped. The newly designed PNG, which could stand with logging-while-drilling environment, has been developed and was confirmed that the PNG could produce enough neutron output. Meanwhile, prototypes of the LWD has been designed and manufactured to carry out field testing. (author)

    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)

    An examination was made on the structures of CO2 emission in the Korean manufacturing sector for the purpose of drafting measures for regulating and controlling CO2 emission. With the use of a list of interactive industries, the emission was determined on the assumption that CO2 was discharged by the consumption of fossil fuel. 1985 and 1990 were chosen as the years to be examined. The industries with a large quantity of emission were construction, transportation, storage, communication and metal products/machinery. The largest factor that influenced the increase in the emission was the growth of the ultimate domestic demand, and the next factor was export. On the other hand, a factor worked in the direction of reducing the emission was the change in the emission coefficient and technical changes. It would be important that measures for CO2 emission control be centered for a short term on regulating the industry that has a high induced coefficient (using products from other industries having a high CO2 emission coefficient as intermediate products), and for a long term on regulating the ultimate domestic demand and export. The changes in the emission coefficient and the changes in technology would also be important in reducing the emission as well as the reform of the industrial structure. 2 refs., 3 figs., 2 tabs.

    A hybrid or mixed structure (composite structures) are a matter of increasing concern which takes in each advantage of steel and concrete. A field of bridges is no exception, with the plan and construction carried out for the new type of composite bridge, such as a composite cable-stayed bridge and a composite extra dose bridge as a long span bridge, and a composite truss bridge and a corrugated steel plate web bridge as a medium-span bridge, with technological development becoming active in this field. In such a technological trend, a hybrid two-girder structure was devised, a structure consisting of a concrete filled steel pipe for a girder and a precast (PC) floor plate for a floor board, as the girder structure of a long-span cable-stayed bridge in the subject research; also, applicability was examined using, as an example, the composite cable-stayed bridge with hybrid girders employed for the span. This paper reports the result of the analysis of the entire system, the analysis made for the purpose of examining the characteristic and the feasibility of this hybrid girder. The analysis revealed the structural feasibility of the long-span composite cable-stayed bridge using two hybrid girders of concrete-filled steel pipes thus devised. (NEDO)

    On the insert reinforcing bar structure for the connecting part of the main tower of cable stayed bridges, this paper reports verification results on a load resistant safety with a full-scale model, structure analysis and construction work. The basic structure was composed of a drilled steel shell, inserted reinforcing bars, fixing structure of bars in lining concrete of the shell and a pressure bearing plate. As an experimental result, the connecting part had a sufficient load carrying capacity against both tensile and compressive loads. The shear stress of the insert reinforcing bar structure was estimated successfully under von Mises`s condition. The shear spring constant in deformation characteristics was linearly proportional to an inserted reinforcing bar ratio. In earthquake, nearly 60% of an allowable compressive load was transferred to concrete through the pressure bearing plate. The analytical results of load resistant deformation characteristics of the connecting part well agreed with experimental ones, and the proposed analytical model was applicable to estimation of a dynamic behavior. 5 refs., 22 figs., 4 tabs.

    Thin-walled box stub columns such as beams of cable-stayed bridge, suspension bridge tower, arch rib of arch bridge and steel piers and so forth can also bear torsion at the same time besides compression and bending. These thin-walled box stub columns may achieve ultimate condition before reaching to plastic condition due to the effect of local buckling and so forth. Accordingly, it is the important topic to study the properties regarding ultimate strength of thin-walled box members in order to evaluate correctly the effect on load bearing resistance of local buckling. In this report, validity of load bearing resistance curve and ultimate strength interaction curve proposed by authors was studied using load bearing capacity experiment results. As a result, all ultimate strengths obtained by the experiment were higher than the ultimate strengths estimated by load bearing capacity curve and ultimate strength interaction curve. Further, it was revealed that the specimens subjected to torsion or subjected to bending and torsion and so forth exceeded the plastic strength due to the effect of strain hardening. 12 refs., 14 figs., 4 tabs.

    Examination was conducted in detail on an MHD generation system by coal combustion, with the results reported. Concerning a gas table calculation program in coal combustion, it was prepared assuming 100% slag removal ratio in the combustor as the primary approximation. A combustor for MHD generation needs to efficiently burn fuel using high temperature pre-heated air as the oxidant, to fully dissociate/electrolytically dissociate seed, and to supply to the generation channel a high speed combustion gas plasma having a high electrical conductivity which is required for MHD generation. This year, an examination was conducted on technological problems in burning coal in an MHD combustor. As for the NOx elimination system in an MHD generation plant, an examination was made if the method studied so far in MHD generation using heavy oil as the fuel is applicable to coal. Also investigated and reviewed were various characteristics, change in physical properties, recovery method, etc., in a mixed state of seed and slag in the case of coal combustion MHD. (NEDO)

    The paper investigated/studied `space light modulation materials,` `dynamic hologram/memory materials,` `optical waveguide path materials,` etc. which become key materials in the high speed two dimensional processing. As to electrooptical materials proposed in this investigational study, the external electric field and the electric charges generated make quality of molecules themselves directly change to memory strong/weak signals of light. Therefore, the response velocity becomes less than a millionth of that of the liquid crystal display, and high speed which is needed for realtime moving image processing is anticipated. Hologram includes the phase information in addition to information on light strength. Therefore, it is a large capacity record medium and at the same time a record medium which can read/write two dimensional information as it is. With optical fiber, images cannot be transmitted as they are. Light waveguide path materials are those that accumulate roles of mirror and lens in a sheet of the material and construct a system which is strong in vibration, as optical parts connecting among materials for two dimensional data processing. 273 refs., 107 figs., 17 tabs.

As to the study of the high temperature superconductivity mechanism, it was found out that a theoretical model of the strong scattering limit in d-wave superconductor can be used for the breaking of superconductivity due to Zn impurities. Concerning the study of the critical current mechanism, the elucidation was proceeded with of the magnetic flux pinning and grain-boundary conduction mechanism. Relating to the development of element technology of bulks with great electromagnetic force, the mechanical strength of superconducting bulk materials was raised to 100MPa or more by the epoxy resin impregnation method. As to the development of the basic technology for fabrication of high next-generation current conductors, the expansion was confirmed of conditions for growing single grains in the zone-melt process for very fine filaments. About the development of technology of single crystal substrates, in the development of the pseudo single crystalline film growth process by LPE method, a yield ratio of high quality crystal of 63% was achieved. Concerning the development of technology of thin film/multi-layer, the area of uniform composition/thickness of NdBa{sub 2}Cu{sub 3}O{sub 7-x} MOCVD films was enlarged up to 20mm square. (NEDO)

    The research and development have been conducted to apply neural networks to interpretation technique for 3-D MT data. In this study, a data base of various data was made from the numerical modeling of 3-D fault model, and the data base management system was constructed. In addition, an unsupervised neural network for treating noise and a supervised neural network for estimating fault parameters such as dip, strike and specific resistance were made, and a basic neural network system was constructed. As a result of the application to the various data, basically sufficient performance for estimating the fault parameters was confirmed. Thus, the optimum MT data for this system were selected.

    It was intended to serve for establishing specifications for a next generation SAR such as PALSAR through studying methods for evaluating and utilizing the multi-frequency, multi-polarized wave SAR data. Placing an emphasis on utilization of the NASA`s AIRSAR, identification was made on backscatter amount recorded on the SAR data, terrestrial constitutional substances, patterns of the ground surface, micro-topography and such terrestrial conditions as vegetation and land utilization. Their mutual relationships were also analyzed. A noise reduction method usable on multi-band data can be applied to the AIRSAR data, and can reduce noise effectively. Images with more volume of information can be acquired from multi-band images with the same polarization wave than from multi-polarization wave images with the same band. As a result of estimating terrestrial permitivity by using the method invented by Dubois and van Zyl, most of the subject area is judged to have terrestrial substances dried at the time of having acquired the images. A colluvium rich with exposed rock regions and gravels was identified as an area having higher permitivity than the former area. Images of terrestrial roughness were divided largely into smooth flat lands, sand and gravel distributed regions, exposed rock regions, and plant distributed regions along river basins. 3 refs., 2 figs., 1 tab.

    With an objective to detect gas leaking from an underground gas pipeline, discussions have been given on a method which utilizes acoustic characteristics of leakage. On leaking sound generated from damaged portions, the form of damaging was hypothesized as pinholes, and spectra of leaking sounds from holes with different diameters were measured. The dominant frequency decreases as the hole diameter increases, while it is in a region of relatively high frequency of 1 kHz or higher. However, detection from the ground surface was impossible when cover soil has thickness from 0.5 to 1.5 m. In an experiment to measure leaking sound inside the pipe, pressure in the pipe was adjusted to 0.02 atm which is a standard pressure for a low-pressure pipe, and the sound was measured when the hole diameters were varied. In any of the results obtained by varying the hole diameter, spectra having the dominant frequency in the region of 1 kHz or higher were measured. In addition, it was found that sound pressure difference of as much as 50 dB at maximum is generated as compared with a case of no sound leakage. The above results verified that monitoring the high frequency of 1 kHz or higher is effective in detecting leakage from small damages. 2 refs., 4 figs.

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

    The elastic response of VLFS of 1200m long in wave was studied experimentally using a water tank and integral elastic model of 1/80 scale. As offshore airport, a ultra- thin box type floating structure of 5km long, 1km wide and several meter thick is used, and the effect of elasticity is not negligible for such a structure. The experiment used a water tank of 160m long, 30m wide and 3.1m deep. Supposing a water depth of 20m for real VLFSs, the experiment was carried out mainly in a local shallow water area prepared with a temporary bottom together with that in a deep water area. A simple mooring equipment with a linear spring equivalent to real VLFSs was used. The integral floating model was prepared by not mechanical but welded junction to obtain uniform elasticity. The response in wave showed a complicated 3-D behavior, offering useful data for verification of a behavior estimation method. The response was nearly equal between shallow and deep water areas at the same wave length, and the response amplitude in regular waves was equivalent to the significant amplitude in long and short crested irregular waves. 7 refs., 8 figs., 3 tabs.

    With types of general cargo vessel and VLCC vessel as the object of discussion, a method was discussed to estimate fluid force acting theoretically on a hull during maneuvering movement, taking frame line shape into consideration. A vortex model was improved by giving consideration of time-based decay on intensity of discrete vortex lines based on the Rankine vortex. Modeling of flow fields around a hull was attempted to deal with movements in which width and draft are small as compared with the ship length, and turning angle speed and deviation angle are small. It was assumed that the ship speed is slow and effects of waves can be disregarded. Specular images of the hull were taken with regard to free surface, and handled as a double body model. Speed potential to express flow fields around a hull is required to satisfy the following five boundary conditions of Laplace, substance surface, free vortex layers, infinity and exfoliation. The potential may be handled as a two-dimensional problem in a field near the hull by using assumption of a slender and long body and conformal mapping. It was found possible to estimate hull fluid force with relatively good accuracy. Fine linear coefficients derived from the estimation were used to have performed highly accurate determination on course stabilization. 5 refs., 6 figs., 2 tabs.

    A variable cycle engine has been researched and developed for the first time for civilian plane engines, to simultaneously satisfy high bypass ratio, which is required for reducing noise during landing/taking-off and fuel efficiency during low-speed flight, and low bypass ratio required to keep high specific thrust during high-speed cruising. This project is aimed at development of the thrust systems for supersonic planes of the next generation, expected to be placed into commission at the beginning of the next century to replace (Concorde) now in service. The newly developed techniques for realizing variable cycle engines include stationary blade mechanisms for variable, low-pressure turbines serviceable at high temperature, fans of high load/efficiency, compressors of high load/efficiency and wide surging allowance, multi-variable control, and variable cycle performance prediction procedure. Their validity has been demonstrated and confirmed by, e.g., the aerodynamic tests. The heat-resistant engine designs and temperature predicting techniques, including advanced cooling techniques for, e.g., high-pressure turbines and combustors, have been used to satisfy the high specific thrust requirements during high-speed cruising by developing the gas generator working at the world's highest turbine inlet temperature of 1700 degrees C. Their validity has been demonstrated by the continuous operation at 1700 degrees C. For reducing noise, which is very important especially for jet noise, field engine tests were conducted for mixer ejector nozzles and ceramic panels for acoustic absorption. Bright prospects have been obtained to reduce noise to the level specified by the international standards for sub-sonic planes. (translated by NEDO)

    This paper describes an R and D plan for next generation marine gas turbines or super marine gas turbines (SMGT) with low environmental load and high efficiency. A gas turbine can make NOx exhaust amount remarkably smaller than a diesel engine because of its combustion pattern, where making marine exhaust gas cleaner can be expected. In addition, demands are made on modernization of ocean vessels, particularly higher speeds applied to domestic vessels, improvement in environment in vessels, and reduction of labors inside vessels. These requirements may be met by such characteristics of gas turbines as small size, light weight, low vibration and noise, and easiness in maintenance. Therefore, it has been decided to develop a marine gas turbine of 2500-kW class assuming a main engine in a domestic vessel. The development is targeted on NOx exhaust amount of 1 g/kwh or less (about 1/10 of diesel engines), thermal efficiency of 38 to 40% (nearly equivalent to high-speed diesel engines), and use of heavy oil A as fuel. The R&D activities have begun upon inauguration of the Technology Study Association in April 1997. Time period scheduled for the development is six years. (NEDO)

    When symmetrical gradient compositions like ceramics/metal/ceramics are adopted, composites having a large compressive residual stress in the surface ceramics layer can be fabricated. For the symmetrical gradient composition materials, such as Al2O3/TiC/Ni/TiC/Al2O3, it was clarified from the preliminary studies that their toughness was enhanced in 50 to 300%, their hardness in 10 to 20%, and their bending strength in 200 to 300% compared with the usual sintered alumina. In this study, such symmetrical gradient composition structures were designed and fabricated, to intend to enhance the ceramics in the surface layer. For the sintering process, the nitriding reaction heat of Si was utilized in the high pressure nitrogen gas, and the SHS/HIP method was applied, by which inhomogeneous materials with different sintering temperatures in individual parts can be sintered. The heat impact resistant properties of materials fabricated by this process were experimentally evaluated, and the thermal stress analysis was conducted to clarify the improvement mechanism of their heat impact resistant properties. Fundamental data were obtained, as to the development of super high temperature materials, which can be used stably even under the severe conditions. 13 refs., 36 figs., 10 tabs.

Analysis and improvement of the nif genes were performed in 3 species of nitrogen-fixing bacteria in the rhizoshere of rice. (1) In an facultative anaerobe, K. oxytoca, the repressor gene, nifL was destroyed, and the activator gene, nifA was fortified, to attain a novel mutant strain R16, which fixes nitrogen even in the presence of NH{sub 4}{sup +}. (2) In a microaerophilic nitrogen fixer, A. lipoferum, the regulatory genes draT and draG were cloned and analysed, and an improved strain TA1 was obtained by introduction of K. oxytoca nifA gene. (3) In an aerobic nitrogen-fixer S. paucimobilis, the nifA gene was cloned and sequenced, and the activity was expressed in E. coil to show that the product activates the nif promoters of Azospirillurn and Klebsiella. (4) The improved strains K. oxytoca R16 and A. lipoferun TA1 were inoculated to rice plant cultured in a pot without addition of nitrogen source. The inoculated plant showed twice as much dry weight as the noninoculated plant, showing that the improved strains are effective to stimulate the growth of rice. (NEDO)

    A joint research had been carried out with a subsidy from the Agency of Natural Resources and Energy since fiscal 1988 to fiscal 1995 on the direct iron ore smelting reduction process (DIOS process). The process utilizes coal directly as a process to use the strong points and supplement the weak points of the blast furnace process. During the period, a pilot plant had been operated since 1993. Upon having completed the feasibility study, this paper reports the result thereof. The main facilities consist of a smelting and reducing furnace of iron bath type, a spare reducing furnace of fluidized bed type, and a preheating furnace. The former two furnaces constitute a unit structure with the two furnaces connected vertically. The pilot plant achieved a three-day continuous operation producing 500 tons of iron every day. The production rate reached 21 tons an hour at an upward oxygen blowing velocity of about 13,000 Nm {sup 3} per hour. The coal unit requirement showed a result of <1000 kg/t for high VM coal and <900 kg/t for low VM coal. These results verified a possibility that this process can supplement or replace the blast furnace process even for a production scale of 9000 tons a day. 7 refs., 15 figs., 3 tabs.

    The effect of surface tension on free surface flow around floating models is discussed experimentally and numerically. Three-dimensional free surface flow around vertical circular cylinders floating in a circulating water channel was visually observed, where a surface-active agent was added to water. The results are analyzed using Weber number. The numerical analysis was done for vertical cylinder and CY100 models using the Rankine source method. Weber number of at least around 120 is necessary to eliminate the effect of surface tension from free surface flow around the CY100 model. The numerical analysis for the cylinder model needs simulation with wavelength shorter than that of free surface wave used by the Rankine source method. The model for the resistance test should be at least around 7m long to eliminate the effect of surface tension at Froude number of 0.1 or higher. 15 refs., 12 figs., 2 tabs.

    A method to predict drift force acting on a floating structure has been developed for a marine structure consisting of a number of floating elements, positioned in a region having a slope at the sea bottom. When a huge marine structure, such as floating air port, is located in a coastal area, scale of the overall structure is very large, of the order of scale of water depth change. The new method assumes that a marine structure consisting of an infinite number of cylindrical floating elements is installed in parallel to the seashore, where symmetrical nature of the configuration allows to predict behavior of the whole system by analyzing one element. Integration of pressures acting on structure surfaces determines the horizontal component of the drift force acting on the structure. Being influenced by topography, drift force predicted peaks at a frequency different from that for the level predicted on the assumption of constant water depth. This indicates the necessity for consideration of seabottom slope and effects of broken waves at the seashore. 6 refs., 12 figs.

    The geographical position or environment is set on the assumption that the natural energy of a detached house is used in a hybrid state. Moreover, the energy consumption of the house and the natural energy supply obtained from the geographical position were compared and investigated. As a result, the energy consumption is 10,617 kWh, and the energy supply is 8,236 kWh. About 78% of the whole consumption can be theoretically made from natural energy. The energy supply is calculated on the low side during prediction. Therefore, an increase in the energy supply is expected by installing a solar collector based on solar energy, expanding the solar panel area, and increasing the number of wind mills. However, this energy is partially lost via an inverter while it is supplied to the general domestic equipment. At the six main points in Tokyo and its districts, the adaptability of natural energy used based on the regional characteristics is investigated presently and the installation of a system is examined. 13 refs., 2 figs., 6 tabs.

    A permanent borehole energy storage system utilizing solar energy and waste heat from coolers is simulated, to be used as an air conditioning system for super-tall buildings. A 100m-long pipe is buried vertically into the ground, and a heat medium is caused to circulate in the pipe for the exchange of heat with the soil. Thirty borehole units are used, each measuring 9m{times}9m (with the pipe pitch being 3m). Solar cells occupying half of the wall surface facing south and solar collectors installed on the roof supply electric power and heat for cooling and warming. Heat in the ground is transferred mainly by conduction but also is carried by water and gas in movement. So, an analysis is carried out using an equation in which heat and water move at the same time. Because waste heat from cooling and warming systems is accumulated in the ground and none is discharged into the air, big cities will be protected from warming (from developing heat islands). As compared with the conventional boiler-aided air conditioning system, a hybrid borehole system incorporating solar collectors and solar cells will bring about an 80% reduction in CO2 emission and annual energy consumption. 7 refs., 3 figs., 4 tabs.

    Features of a straight wing type vertical axis wind turbine (VAW) and its airfoil sections were studied. The wind turbine in which various aerodynamic work components are mounted on the rotation axis normal to the ground surface is named VAW. Like the airfoil section of aircraft, in lift type VAW, wind turbines were driven by lift 70-90 times as large as drag in some cases. Features of the VAW airfoil section which is a straight wing in plan and a fixed pitch wing (with a fixed angle to a blade support arm) in cross section, and those of wind turbines were studied. Some factors affecting the features, work principle and performance of VAW were clarified. On airfoil sections, products of each weight function and each corresponding aerodynamic factor (lift, drag and pitching moment factors) were plotted on an attack angle ({alpha}) axis. From the conditions for increasing the total sum of areas drawn by the products on the {alpha} axis, various characteristics required for airfoil sections were clarified. Such characteristics nearly agreed between an airfoil section for favorable starting characteristics and that for high efficiency. 3 refs., 7 figs.

    Studies have been made about a heat accumulation tank type cooling system making use of radiation cooling that is a kind of natural energy. The daily operating cycle of the cooling system is described below. A heat pump air conditioner performs cooling during the daytime and the exhaust heat is stored in a latent heat accumulation tank; the heat is then used for the bath and tapwater in the evening; at night radiation cooling is utilized to remove the heat remnant in the tank for the solidification of the phase change material (PCM); the solidified PCM serves as the cold heat source for the heat pump air conditioner to perform cooling. The new system decelerates urban area warming because it emits the cooler-generated waste heat not into the atmosphere but into space taking advantage of radiation cooling. Again, the cooler-generated waste heat may be utilized for energy saving and power levelling. For the examination of nighttime radiation cooling characteristics, CaCl2-5H2O and Na2HPO4-12H2O were tested as the PCM. Water was used as the heating medium. In the case of a PCM high in latent heat capacity, some work has to be done for insuring sufficient heat exchange for it by, for instance, rendering the flow rate low. The coefficient of performance of the system discussed here is three times higher than that of the air-cooled type heat pump system. 8 refs., 5 figs., 4 tabs.

    In response to demand for the expansion of living space, the living environment of semi-underground room has been investigated. An attached green house (passive solar house) is adjacent to the semi-underground room. This is reinforced concrete construction, having flat type solar collector on its roof and lighting window in its north side. It does not have artificial air conditioners. Based on the measurements of daylight factor, artificial lighting is not required at the window in the daytime, but it is desirable to use daylight and artificial lighting together at the center. The performance of sound insulation depends on the high performance soundproof sash level. There is less daily temperature variation due to its large heat capacity, and less yearly temperature variation than the outside. By shielding the solar radiation, the insolation in the green house in summer can be restricted in the same as in winter. The insolation can be easily received in winter due to its large vertical intensity of solar radiation. The green house in the south side is useful for improving the living environment of semi-underground room. The temperature rise in the semi-underground room can be restricted by opening window in summer. It is desirable for the comfortable living to use artificial cooling to reduce the daytime temperature by 3 to 4{degree}C. In winter, it is comfortable to heat by 4 to 5{degree}C. 2 refs., 7 figs.

    Dynamic creeping phenomena aere investigated using natural rubber NR, solution-polymerized SBR, and a single system rubber filled with carbon black in the modified SBR{sup {asterisk}} added with functional froups into the end of its rubber molecules, and their blended rubbres of SBR/NR and SBR{sup {asterisk}}/NR. The following conclusions were obtained: The amount of dynamic creep is expressed as the sum of the creep {epsilon}{sub 1} induced by broken physical bonding due to interactions between polymer chains, the creep {epsilon}{sub 2} induced by the transformation of filled particle structure into a stable structure, and the creep {epsilon}{sub 3} induced by phase separation of a blended structure. The SBR{sup {asterisk}} blended system has small amount of physical bond, and the filled particles form a stably oriented structure, without an NR phase separation phenomenon observed during the creep process. Thus, this system was found to have much smaller dynamic creep than the SBR blended system. 4 refs., 16 fugs., 4 tabs.

    The purpose of this study is to investigate fatigue processes, fatigue life times and fatigue fracture patterns by three-dimentional stresses on carbon black filled blended rubbers of solution-polymerized SBR and SBR{sup *} modified at the end of SBR polymer chains by functional groups with NR. In the experiment, specimens consisting of 7 kinds of NR/SBR{sup *} blended rubber and 3 kinds of NR/SBR blended rubber were put to the three-dimentional stresses test. The average value of physical properties as well as characteristic values of anisotropy and fatigue fractures were measured. As a result, the following conclusions have been derived: In rubber phases of NR and SBR,or SBR{sup *}, compatible structures were formed by polymer chains of NR and SBR(SBR{sup *}) at their boundaries and they became obstacles to the propagations of micro-cracks generated by fatigue. Fracture patterns were controlled by velocities of a formation process of anisotropic layer structures and a generation process of surface cracks. Fractures grew in lateral direction in NR system,because the formation of anisotropic layer structures was faster. Fractures grew in radial direction in blended rubber systems,because the formation of surface cracks was faster. 6 refs., 26 figs., 2 tabs.

    The unsaturated vertical flow through snow was analyzed with a model prepared to rationally express the progression of moisture movement through porous media. For the model, the moisture existing in the two-phase mixture was assumed to be composed of free phase and trapping phase. It was then presumed that the aqueous behavior complied with the conservation law of moisture in both phases and Darcy law expanded to the aqueous transfer in the free phase. The thus derived basic equation was analytically solved by linear approximation. The result of calculation was applied to the experimental result on the granulated snow samples which had considerably progressed in metamorphosis. As a result of application, it was known that the present model correctly reproduces the run-off from the snow sample, when it is more or less abundant after its rising. Pertaining to the parameters to structure the model, it was indicated that K, {alpha} and {beta} express the starting time of run-off, damping part of run-off, and trapping mechanism and flow characteristics, respectively. 8 refs., 5 figs., 2 tabs.

    Research is conducted into burdens to be imposed on the nurse and the attended person during nursing activities and into measures to lighten such burdens, and basic data are collected about physical strains to be produced when raising a patient on the bed, pushing a wheelchair, and about stool shapes appropriate for the aged. In a study about escape from a disaster, many shortcomings are discovered requiring remedy, such as difference in height and doors failing to open in case of power outage. For communication in case of emergency, it is concluded that the most promising method will be a combination of a mobile computer and handyphone system. A photoelectric pulse wave monitoring system and an acceleration sensor-equipped water bed, on which the patient lies unrestrained for the measurement of heartbeats and respiration waveforms, are developed. A concept wheelchair is under development which will be a 2-motor 4-wheel design, to be equipped with a steering wheel and a vertically movable seat which will facilitate boarding and alighting. Many projects are in store for fiscal 2001, which include the development of a system to ensure sitting position stability and an automatic pressure belt for the prevention of orthostatic hypotension.

    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)

    With an objective for spatial continuous measurement of physical, chemical and biological amounts in ocean, development has been made on a wing controlled towed vehicle, `Flying Fish` which is capable of controlling depth, pitch and roll. Numerical simulations and two-year sea experiments have been carried out for the development. Flying Fish consists of a sub-system comprising a towing vehicle, towing cables, and on-board controllers. In a steady state, Flying Fish can be controlled at accuracy for depth of {plus_minus} 0.05m, pitch of {plus_minus} one degree, and roll of {plus_minus} 0.5 degree. This accuracy is sufficient for operating a chemical analyzer, the dissolved carbonic acid analyzer. Even in a non-steady state such as in changing the depth, the pitch can be controlled at {plus_minus} 3 degrees and the roll at {plus_minus} 0.5 degree. This extent of attitude change is within a range rendering no problems in maintaining accuracy of the measurement devices. The result of sea experiments for movements of Flying Fish agreed with that of the numerical simulation at practically usable accuracy. Flying Fish is verified as an effective system in investigating spatial variations in ocean data. 10 refs., 15 figs., 1 tab.

    A floating structure such as an international airport is anticipated to have a length of about 5,000 m and a width of about 1,000 m. A singular point method may be used as a method to estimate force that such a floating body is subjected to from waves. In order to derive a solution with practically sufficient accuracy, 1250 elements are required in the length direction and 250 elements in the width direction, or a total of 312,500 elements. Calculating this number of elements should use finally a linear equation system handling complex coefficients comprising 312,500 elements, which would require a huge amount of calculation time. This paper proposes a method to derive solution on wave forces acting on a super-large floating structure or fluid force coefficients such as added mass coefficients and decay coefficients at a practically workable calculation amount and still without degrading the accuracy. The structure was assumed to be a box-shaped structure. Strengths of the singular points to be distributed on each element were assumed to be almost constant except for edges in lateral, oblique and longitudinal waves. Under this assumption, the interior of the floating structure excepting its edges was represented by several large elements to have reduced the number of elements. A calculation method proposed based on this conception was verified of its effectiveness. 2 refs., 25 figs., 3 tabs.

    Mankind is currently confronted by several environmental problems. Among these problems are depletion of fossil fuel reseves, and global warming caused by CO {sub 2} and the consequent environmental damage. These problems demand the most serious consideration and solution. Fuel cell systems are one of the prospective energy systems. Fuel cell systems produce electricity electrochemically, and they produce it most efficiently, and with almost a complete absence of emissions. This basic study concerns the production of hydrogen. Hydrogen is the fuel used by fuel cells. Hydrogen is produced by the electrolysis of water with solar energy. In this paper, as a first step, the hydrogen generator {prime} s properties are measured. These properties are measured by supplying electricity both continuously and intermittently from a DC power source which simulates photovoltaic modules. Our conclusion is that, in the near future, utilization of a hydrogen generator may be feasible if electricity is supplied from photovoltaic modules. 3 refs., 12 figs., 2 tabs.

    The effect of micro-gravity on bio-functions and vital reaction was studied using the facility of Underground Gravity-free Experiment Center Co. On the effect on osteoblast shape and gene expression, although fluorochrome reacting with Ca was well taken into cells, no significant difference in Ca content in cells was observed before/after falling. Expression of genes related to cell propagation was controlled under micro-gravity. Protoplast fusion of Lentinus was unaffected by micro-gravity. The mRNA fragments of gravity sensitive mutant of rice plant were affected by micro-gravity. Paramecium was set swimming in solutions with different specific gravities. The reaction behavior of Paramecium was affected by the difference in specific gravity between cell bodies and solutions. The water content metabolism functions of a mouse with needle stimulus, in particular excretory, were slightly promoted by micro- gravity. The cortisol level in blood of a falling mouse group rose showing strong stress. As the preliminary study on the geotaxis of insects, motion of bagworm was observed. 12 refs., 38 figs., 4 tabs.

    For the development of antioxidants that are high in use value, peptides are produced in a bioreactor from so-far-unused or little-used protein resources originating in marine organisms collected along the Sanriku coast, and antioxidants that they may contain are searched for. Three kinds of red alga, eight kinds of brown alga, and internal organs of processed fish are treated in the bioreactor. The bioreactor is a rotary membrane type especially built for the effective decomposition of proteins in this study. Reaction solutions containing proteins and enzymes are let through an ultrafiltration membrane module in rotation at a high speed, and the products with their molecules reduced in weight are effectively taken out of the system (free of clogging). The specimens checked for antioxidant features are all found to be positive when subjected to the iron rhodanide method or carotene method, the two methods determining the change in the amount of oxygen in hydroperoxide and {beta}-carotene that are produced when the linolic acid is oxidized. Every one of the specimens prepared for this study exhibits antioxidant features in plural, different mechanisms. It is necessary to collect further basic findings about oxidation inhibiting mechanisms for the development of more active antioxidant peptides. 39 refs., 46 figs., 8 tabs.

    The water vapor adsorption desorption isotherms of purified and/or synthesized sepiolite, allophane, diatomite, selectively leached kaolin and mesoporous silica were measured to develop humidity control materials in living environments. Based on Kelvin's capillary condensation theory, suitable pore diameters for controlling relative humidity at 40 and 70% were calculated to be 3.2 and 7.4 nm, respectively. Wakkanai diatomite, purified allophane, selectively leached kaolin and mesoporous silica have suitable pore diameters and high water adsorptivity, and were considered as candidates for humidity self-control materials. Among these materials, mesoporous silica formed as a tile showed the best performance as a humidity control material in desiccator and model house levels. (author)

    For the purpose of grasping the present situation of the development/production/spread of welfare apparatus in north Europe, an investigation was conducted paying visits to Sweden and Denmark. Basically in the Swedish policy for handicapped persons, disablement is defined not only as features which belong to each individual, but as problems arising when the environment surrounding each individual touches one another. Moreover, characteristics of their policies on welfare apparatus are that major welfare apparatus can be provided for the disabled free of charge, and that the government and public organs play a major role in each step of the development, evaluation, distribution and provision of welfare apparatus. Features of the market of welfare apparatus are that users and buyers of the apparatus are different persons, that a public corporation called SUB participates in determining selling prices, etc., and that the market reflects needs and requests from users comparatively naturally. The needs for welfare apparatus at the Research Institute of Handicapped Persons are grasped through opinion exchanges with groups of handicapped persons or information exchanges with the technical aid center. 3 refs., 11 figs., 10 tabs.

    The difference in result of control by the control system was studied by designing the vehicle follow-up control for the platooning of automobile. A comparison was made between the sliding control based on the non-linear control theory, and PID control which is judged to be the most primitive. A two-wheel model of four-wheel vehicle was used as a vehicle model, while the automobile model was composed of non-linear factors, which were an engine, torque converter, gear shift map and tires. When the initial figure of both distance between and speed of vehicles is close to their target figure (less than {plus_minus}8m and {plus_minus}5km/h, respectively), a good result of control can be given by both the sliding control and PID control, so that the former control was known to be as very effective as the latter control. When the initial figure of both distance between cars and speed of vehicles is less close to their target figure (less than {plus_minus}20m and {plus_minus}5km/h, respectively), the sliding control is higher in convergency than the PID control. It was thus known that the former control gives an effective result of control even if the inititial value is far. 6 refs., 16 figs., 1 tab.

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

    There are 14 floodways built from the mid-Tokygawa era up to now in the Nigata Plain and the most important and large-scaled one in these is the Okozu floodway. The plan of the Okozu floodway which is playing its wonderful role to control flood may be considered to begin in 1730s, Edo era, but it was not practiced by Tokugawa. The necessity for the Okozu floodway to control flood in the Nigata Plain had been confirmed by the floods happening continuously in the 1880s. The excavation construction was begun in 1909, about 200 years after the plan. The work started by using modern flood control techniques and the floodway came into practical use in 1922. In the present paper, the history of flood control in the Nigata Plain from 1730s to the modern times has been traced. Using the results, the development of the modernization of flood control technique centered at weirs and gates has been studied. 44 refs., 5 figs., 1 tab.

    Rocks and concretes are split in urban areas or in the vicinity of important structures frequently in the recent years, where a process using blast-free hydraulic splitter or expansive splitter is used. This paper describes a basic study to utilize the recovery force of TiNi shape memory alloy as a pressure source. Experiments were carried out on TiNi alloy for its recovery force and deformation characteristics after a biaxial compressive deformation under various compositions and heat treatment conditions. As a result, it was found that within the range of the experiments the TI-60.5 Ni processed and heat treated material is most suitable as a pressure source under normal temperatures, and its maximum recovery force reaches 600 MPa. Giving considerations on the relation between crack developing conditions and loading angles in the case where a uniaxial compressive loading is performed on a bore hall drilled wall, a rock splitting device using TiNi was fabricated on a trial basis and experimented. The result showed that it has a splitting force capable to break ultra hard rocks with the maximum unit splitting force at 3-5 t/cm and the maximum stroke rate at 2-3%. The device has split the test rock specimens within several minutes. 17 refs., 15 figs., 1 tab.

By elucidating the mechanism, the paper aimed at quantitatively controlling the heat generation. The R and D period was four years from fiscal 1993, and the details of the research are about the excess heat measuring test, material analysis/development tests, test on detection of reaction products, information collection/arrangement, international research cooperation. As a result of the research, a part of the excess heat measurement was surely able to be reproduced. However, when a confirmation experiment on the excess heat was conducted by another more positive method under the same conditions, it was found that the excess heat quantity was not the absolute excess heat quantity exceeding the measuring sensitivity/errors of the system. Supposing the excess heat of 0.1W order is generated in nuclear reaction, any of reaction products should be detected in a considerable quantity. However, no reaction products were not detected. 42 refs., 241 figs., 55 tabs.

    Creation of new biocatalysts was surveyed to convert chemical reactions into environment-friendly processes. Biocatalysts are characterized by their high catalytic activity, uniqueness of reactions, and non-pollution under mild conditions. Stability is required for them, such as heat resistance, solvent resistance, acid resistance and alkali resistance, under severe conditions. For the development of new biocatalysts, it is necessary to multiply utilize the techniques containing enzymes, ribozymes, mold synthetic polymers, chemical modification, and non-natural proteins. Natural enzymes have been conventionally improved through the search, imitation and modification. Hereafter, new biocatalysts with functions required for the reactions should be created by integrating information regarding functions, structures and activation of these enzymes. It is indispensable to cooperate closely with supporting techniques, such as gene engineering, organic synthesis, biophysics and computer chemistry. 35 refs., 26 figs., 1 tab.

In addition, the boundary element method was used to conduct similar calculations to verify the methodological reasonability. As a result of discussions, the following results were obtained: a seaquake load has a resonant point which corresponds to an intrinsic value of the boundary value problem in a closed region; the resonant point moves according to width of the floating body, and the frequency moves to higher frequency side when water depth is shallower; compressibility of fluid cannot be ignored in the vicinity of the frequency for the resonant point; the seaquake load is proportional to width of a vibrating ground on the sea bottom, and the load in the vertical direction decreases when the center of the floating body is separated from the vibrating ground; a load in the horizontal direction presents no problems in a floating body with a shallow draft; and a moment in the lateral direction may present a larger problem than in the load in the vertical direction. 8 refs., 8 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.

    With an objective to clarify basic performance of hydrofoils, a towing experiment was carried out on single hydrofoil and tandem hydrofoils, whose results are reported in this paper. In the experiment, the tandem hydrofoils are supported on two stays on the left and right sides, and the whole lifting power and the whole drag including those of the stays were measured by using strain gauges placed on four plate springs. Results of the experiment may be summarized as follows: in the case of the single hydrofoil, the lifting power constant varied as a result of strong impact on free surface as the shallower the hydrofoil, but corresponds to the size of the lifting power coefficient in high speed regions; in the case of the tandem hydrofoils, the smaller the submersion depth, the effects grew larger on the lifting power coefficient and the drag coefficient, similarly to the case of the single hydrofoil; and the lifting power coefficient for the leading hydrofoils changes very little as a result of change in horizontal distance between the tandem hydrofoils, but the lifting power coefficient of the rear hydrofoils vibrates due to influence from the leading hydrofoils, with the peak of the value thereof transferring to the higher speed side as the horizontal distance increases. 3 refs., 10 figs., 2 tabs.

    At the Hekinan coal-burning thermal power station of Chubu Electric Power Company, there is a plan to construct its ash dump by closing the neighboring sea area with bulkheads. This bulkhead is deeply embeded steel sheet piles to be struck into a soft clay layer. Since it is necessary to improve the ground in a wide area for stabilization of soft clay, the specifications as well as the scope of improvement of the basic design plan were noticed, a qualitative study of the bulkhead was done by a numerical analysis aiming at realization of a rational and economical bulkhead and an execution plan which modified the above was prepared. In this execution plan, the reduction as much as about 9% became possible for the construction cost of about 1km long bulkheads. In order to demonstrate the adequacy of this execution plan, loading tests were conducted on full-size cellular bulkheads corresponding to the basic plan as well as the execution plan. As a result, the tested values agreed very well with the analytical results and upon comparison between them, the displacement at the tip of the cellular bulkhead and other measured values showed no meaningful difference, thereby it was confirmed that the execution plan had the same level of stability as the basic plan. 5 refs., 26 figs., 5 tabs.

    R and D was conducted on a 'system for monitoring living situation of elderly people' for the purpose of supporting the elderly living alone, with the fiscal 2000 results reported. In the development of a knowledge engineering system, a system was developed estimating the present position of an elderly person in his home or calculating his daily living activities, by analyzing data measured by infrared sensors, and thereby automatically inferring his behavior or health condition. In the research for practicability of the system, infrared sensors and sensors for detecting opening/closing of a door were improved, which included improvement by using telephone lines for example. In the demonstrative experiment, data were obtained which seemed to show a change for the worse of a disability condition due to senile dementia, or else, which appeared to be an inability to move occurring finally as a result of gradual deterioration of health. Another data measured disclosed that elderly people, unlike a normal life pattern, were living in a state with night and day reversed. From these results, the system can safely be said to have a function for monitoring the lives of the elderly people in point of their mind and body. (NEDO)

    An intercellular transport technology (artificial manipulation of an intracellular protein transport system in eucaryotes) is studied for the accumulation of cytotoxic proteins, whose expression has so far been difficult, and activated proteins, which have avoided decomposition, in appropriate intracellular minute organs. The aim is to construct a system to allow foreign proteins high in productivity and quality to express themselves for production in eucaryotes. Basic surveys were conducted of the intracellular biological functions of single-membrane organelles (endoplasmic reticulum, peroxisome, vacuole/lysosome, and Golgi body), the molecular mechanism of protein transport to each organelle, and protein activation and quality control, and element technologies were extracted. For the development of novel pharmaceuticals making use of the intracellular protein transport technology, an activated protein production system was built and a search was made for transport activity impeding substances. Research tasks relative to the development of the new technologies were isolated, such as the visualization of intercellular transport. A survey was made of the market for pharmaceuticals, cosmetics, enzymes, and visualizing equipment (fluorescence microscope provided with new functions), etc. (NEDO)

    Study was conducted of policies on energy spread, trends of energy development, etc. in energy conservation and substitution energy fields after the economic crisis in Asian countries, and the results were summed up. In Thailand, it is expected that the effective use of solar energy can be an effective means as a substitution energy. Further, the energy conservation by demand-side management, etc. is to be urgently taken. Indonesia is abundant in energy resources and does not take energy conservation measures very much. As to petroleum substituting energy, it is expected that the diversified use of coal, natural gas, hydroelectric power, geothermal energy, etc. will be advanced. In Malaysia, a policy in which energy is dispersed to natural gas, hydroelectric power and coal is being taken for reduction of the dependence upon petroleum. In India, joint projects with developed countries are proceeded with in the fields of electric power, energy conservation and renewable energy. In China, the policy for advancing new energy utilization is being taken that the thermal power generation is optimized, hydroelectric power generation is positively adopted, and nuclear power generation is moderately used, according to characteristics in the region.

    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.

    In this validation study, phenomena of excess heat which are said to be generated by electrolysis of deuterium using palladium metal, etc. as electrode are taken as `new hydrogen atomic energy,` and to clarify a possibility of using them as a future energy source, the abnormal heating phenomenon was validated and the mechanism was elucidated. The study targeted quantitative control of heat emissions. The study was finished in 1997, the fifth year from the start. The excess heat measurement could partially be reproduced; however, when conducting a confirmation experiment on the excess heat by another more reliable method under the same condition, it was found that the value of excess heat was not an absolute value exceeding measuring sensitivity and errors of the system. If the excess heat of 0.1W order is to be emitted in nuclear reaction, any reactive product should be detected in a substantial quantity. However, the product of a large quantity was not found. A possibility was found out of an increase in nuclear reaction ratio inside solid by low energy deuterium irradiation. From the above, it was concluded that the use of new hydrogen atomic energy was negative. 20 refs., 149 figs., 29 tabs.

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

A system has started in which electric power companies purchase surplus electric power from the natural energy use power generation such as the wind power and photovoltaic power generation, etc., and a lot of local self-governing bodies in the country plan `projects to promote town` using the system. However, few engineers and makers can plan `a project to promote town,` making effective use of natural energy which is fickle. Therefore, first, the paper arranged the actual status mostly of the cases of `the projects` using natural energy which have been carried out in the country. Next, the trend of the natural energy utilization technology in countries including the U.S. was described. Moreover, assuming model areas in Japan for working out a concept of model projects on the natural energy utilization and town promotion, a concept was proposed making full use of the utilization technology which has now usability. Arrangement is being made for conditions for the full scale spread as seen in the subsidy system for general users. 3 refs., 176 figs., 61 tabs.

    Excessive pumpage of groundwater has caused many problems including land subsidence and sea water intrusion. The Research Group for Water Balance carried out research on the utilization and preservation of groundwater to solve these problems from a socio-scientific perspective. It developed systematized techniques of groundwater basin management and successfully applied these techniques to each problem site. The procedure of groundwater basin management is summarized as follows: hydrogeological analysis of the groundwater basin based on Quaternary geology, prediction of the changes in water balance by computer simulation, and defining of the permissible yield by adopting socio-scientific method. Recently, contamination of groundwater by chlorinated solvents has increased seriously. To solve this problem, it is necessary to introduce the concept of geopollution which covers the contamination of groundwater, geologic units and ground air. Research procedure of groundwater contamination based on this concept was proposed. Its main elements are as follows: (1) preliminary investigation to identify contaminant source, (2) main investigation to clarify the contamination mechanism by method of micro hydrogeological investigations, (3) evaluation and prediction of the contamination, (4) determining the remediation measures, (5) implementation of measures to remove the contaminates, and (6) monitoring. This procedure was combined with techniques of basin management to systematize a management theory of the quality and quantity of groundwater. 42 refs., 7 figs., 1 tab.

    An epidemiological survey survey was performed to elucidate the fungal flora of a dwelling house. The measurements were carried out in an apartment in Yokohama from Jul. 1996 to Dec. 1997. Fungi were isolated from 106 sampling points (the surface of the walls, floors, etc.) with sterile stamps. It was proved that Cladsporium, Penicillium, Eurotium, and Yeasts showed characteristic distribution. Especially Cladsporium was not isolated from the spring to the summer, but increased in the autumn. In addition to the survey, experiments on fungal growth temperature (13, 20, 25, 30, 36, 42 degree C) and water activity (A w 0.75{approx}0.97) were carried out. Cladsporium grew well in 13, 20, 25 and 30 degree C, but didn't grow in 36 and 42 degree C. In addition, the growth activity of Cladsporium was down below Aw 0.91. Eurotium was isolated from under Tatami, where it has an unchanging temperature and relative humidity. Yeasts preferred very high humidity. It was concluded that environmental factors such as temperature and relative humidity related to the growth of fungi. (author)

    This is an ice-aided heat pump system powered by electricity, intended for 'shiitake' mushroom culture. The experimentally built heat pump is used in a 200 square-yard-large shiitake culturing facility in the Kinki district, Japan, and an environmental temperature control test is conducted for a culturing house accommodating 6000 mushroom beds. The cold heat storing capacity in summer is found to be 202Mcal (ice percentage: 66%), and the heat storing capacity in winter 69Mcal (water temperature: 60 degrees). The system is capable of performing air-conditioning while storing heat, and all phases of operation are switched over from one two another automatically, with the exception of the switching between the cooling season and the warming season. In a culturing test conducted in the mushroom beds, with the system kept in operation for approximately 3 months, 5 packs (500g) of mushrooms are collected per bed. This means that the 1-day-1-cycle variable temperature control system achieves an increase of 20 percent over the conventional constant temperature control system which yields only 4 packs. In another test in which 4 kinds of seeds are sown, it is found that variable temperature control is superior to constant temperature control in terms of harvest in the summertime cooling operation.

    The paper stated mostly topics from special lectures. Composite materials have a lot of potentialities, and there are larger expectations in flexible and high-strength soft composites rather than the conventional high rigidity ones. As to micro-machines, the problems are on mechanical property of the element, environment/friction/fracture/life, etc. and the evaluation method of the characteristics was studied. Concerning the research and development of the intellectual structure system, the introductive study has entered the second year. Ultimately, structures have functions similar to those of the living organism had, and conduct self-diagnosis, self-repair and autonomous-response. Railroad structures receive regular inspections according to the rule, and a half of the objects for the inspection are cracks, unbonding and weathering of concrete. With the Hanshin Awaji great earthquake especially, the anti-earthquake reinforcement has been expedited. In various kinds of materials, the finer the crystal particle becomes, the greater the high temperature deforming ability becomes. When the particle size is below the critical particle size, it shows superplasticity. The study is advancing. As to high density secondary batteries, introduced especially were Ni-hydrogen batteries and Li batteries.

    In this study, an improved flat plate structure was developed by an attempt to shift the critical section (the bending yield position) from the column surface towards the span center by increasing the amount of main reinforcement near the column joint. Performance testing of the improved flat plate structure to clarify its basic properties, it showed that its hysteresis characteristics were superior to those of the conventional type (the amount of main reinforcement is uniform in the direction of the axis of member). Based on the experimental results, the appraisal of hysteresis characteristics and the method of section computing were established as the design methods. These newly established design methods were applied to the existing 26-story high-rise building of RC construction, and a simulation was performed to analyze the effectiveness of the improved flat plate structure. The response results satisfied the design criteria for general high-rise buildings, thus confirming the feasibility of constructing high-rise buildings incorporating the flat plate structure.

    Welfare Technohouse Mizusawa was established in June 1998 for the development of a health monitoring system, designed for aged people living alone, under which various sensors function without imposing any restriction on the aged people who do not even feel the presence of such sensors. The contents of the development effort include studies for putting ADL (activities of daily living) remote sensors to practical application, evaluation tests for 16 types of sensors, and narrowing down of the 16 types to a smaller number of serviceable ones (by inputting the outputs of them all into one personal computer and by comparing them with the actual life of aged people). Some aged people are made to stay experimentally at a house of comfortable nursing care, and the resultant data are analyzed and reported. Research and development is conducted of daily necessities, welfare appliances, and living environment-related facilities for people of advanced age. Joint efforts with local enterprises will be propelled forward. In fiscal 1998, 6 people have experienced a 3-night stay at the said technohouse, to be monitored by the said 16 types of sensors. Actually, data worth analysis have been obtained from 8 types only. Several out of the 16 necessary for health monitoring will be installed at the residences of some old people living alone. It is planned that the data to be collected will be exchanged via CATV (community antenna television). (NEDO)

    In an effort at developing nursing equipment, a cursor-controlled system for on-the-screen operation is experimentally constructed, which facilitates the use of indoor electronic devices and help aged persons engaged in in-house work. Vocal communicators are investigated for feasibility. In relation to equipment for mobility training, a dynamic equilibrium function evaluating system is experimentally built, and a system for electric stimulation-aided mobility rehabilitation is studied. Sensors are imbedded into the stool, and an excellent result is obtained in the measurement of the user's weight and the discharged amount. Studies are conducted about algorithm for calculating changes in heartbeats while bathing and about recording electrocardiograms while in bed. For welfare equipment to be effectively utilized at home, it has to be easy to use on the one hand and, on the other hand, house configuration and facilities have to be appropriate for welfare equipment application. It is important to improve the mechanism of providing advice on house modification and to expand financial assistance. A measuring method is developed using the state of the art in sensor technologies for the construction of a system for checking old people's activities of daily living, and their activities are evaluated. The system supplies a sufficient amount of data to grasp their behavior, which shows that it is a serviceable system. (NEDO)

    In order to improve the performance of a multiblade fan, the effects of three types of suction cones of the fan casing on the fan efficiency and noise are investigated experimentally. The first type of the suction cone is the insertion type, which is inserted into the inside of the fan impeller. The second type is the extrusion type, which extrudes outside from the casing surface. The third type is the combination type of two types. The results of those three types are compared with those of the commonly used suction cone. The followings are made clear: (1) The insertion type and the extrusion type are effective in improving the efficiency and reducing noise. (2) The optimal lengths of the insertion and the extrusion exist. (3) The combination type is more effective in improving the efficiency. (4) The combination type with the skewed cutoff of the fan casing shows the best effect. (author)

    In solving the problems in developing technologies peculiar to developing countries, Japan will provide cooperation. This paper describes the achievements in diagnosis and survey in fiscal 1994. Development will be made on a manufacturing process for dimethylether (DME), a synthesizable and portable clean fuel, by using coal produced in China. Annual DME production of 10,000 tons will make it possible to supply 50,000 households with the fuel of one year consumption, whereas return on the construction investment and profit can be expected. At the Shanxi Coal Chemistry Research Institute, a 500 tons a year plant making DME from gasified coal gas is scheduled to begin operation. Development will be made on a pulp manufacturing technology in China, in which environmental pollution due to waste water is largely reduced, and operation cost is reduced. Application of the oxygen-alkaline evaporation and decomposition process developed in Japan will be considered, which uses non-wood raw material such as rice straw, wheat straw and megass). The raw materials are immersed continually in low-concentration alkaline solution, dehydrated, and then lignin is oxidized and decomposed by using oxygen in a continuous oxidation reactor to make the material into pulp. China uses non-wood materials as paper raw materials at 80%, whereas effects are expected in waste water pollution prevention, energy saving, resource saving and economics. (NEDO)

    Generally speaking, finite element methods in the computational fluid dynamics are universal, but not economical. In the present paper in order to overcome this defect ill FEM, we propose a new method using the discrete del operator which is a coordinate-free differential operator in the discrete space. This operator in the discrete space is defined as an element average of the gradient of the shape function and it has three characteristics such as orthogonality, identity and symmetricity. Furthermore the discrete del operator is useful in non-memorizing and in easy coding. As the analytical expression of the discrete del operator is a vector in the two or three dimensions, the natural description of programming becomes objective and compact, which is more understandable for non-specialists of CFD. Here we apply this method to thermal fluid flows at high Reynolds numbers. 10 refs., 5 figs., 1 tab.

    In order to engineer the development of high temperature ceramic turbocharger for the gasoline engine use, characteristics at high temperature were studied of ceramics-made turbine impeller and turbine housing material. Used ceramics is silica nitride, developed for the gas turbine use and sintered under the atmospheric pressure. Prototypically prepared turbine rotors, designed upon studying the centrifugal stress, thermal stress, impeller shape and joint strength between the impellers and metallic shaft, were durable against 1050 centigrade in turbine inlet gas temperature (TIT), as a result of reliability evaluation test thereon. The turbine housing material comprises five categories such as stainless steel, Ni-resist cast iron and N155 (turbocharger housing material for the race use). As a comparative result of high temperature tensile strength, thermal cycle oxidation and thermal fatigue tests, the stainless steel was excellent in oxidation characteristics and at the equal level to the N155 in thermal fatigue strength at 1050 centigrade in TIT. 5 refs., 18 figs., 2 tabs.

    The secondary dental caries easily occur by breeding of bacteria in cavities between living body and composite resin, false tooth or root of tailored tooth as tooth repairing materials. The antibacteria activity of tailored dental materials was thus studied by implanting Ag ion. The antibacteria effect with time after culture of caries bacteria was studied by implanting Ag ion into SiO2 powder, PMMA samples and Ti alloy samples at 20 and 200keV in energy of ion. In addition, the antibacteria activity of SiO2 powder as composite material was found at 25keV which was previously effective for the antibacteria activity. This SiO2 filler (Ag{sup +} filler) showed the antibacteria activity on every bacteria sample after 2h, and in particular, could kill all of 3 kinds of bacteria obtained from a composite resin surface after 12h. The number of living S. salivarius was reduced by half after 12h. The application of the composite resin filler implanted with Ag{sup +} is significant to prevent recurrence of caries. 5 refs., 27 figs., 7 tabs.

    Development is under way of a dry cutting type CNC (computer numerical control) hobbing machine to work on a reduced amount of cutting oil for the purpose of energy conservation. Research efforts are exerted in the five fields of (1) the fabrication and study of a 4-groove master worm/wheel system, (2) fabrication of a high-speed auto-loader, (3) establishment of an effective chip removal method, (4) evaluation of oil-free sliding surfaces, and (5) a study of protection of tooth flanks from damage. In field (1), a 4-groove master worm/wheel system is fabricated to replace the 3-groove master worm/wheel system so as to prevent the worm revolution rate from increasing when the work table revolution rate is higher for speedier cutting work. As for engagement precision which indicates the machining accuracy of a worm/wheel system, which is standardized to be 25 seconds, the newly fabricated system marks 16 seconds in the right revolution and 12 seconds in the reverse revolution. The goals that a high-speed auto-loader is to achieve include a shortened cutting work standby time for energy conservation, prevention of chip accumulation, and prevention of chip caused defective loading.

    A large quantity of cutting oil is used in the cutting work for suppressing tool wear and for improving machining precision. From the viewpoint of energy conservation or environmental protection, use of cutting oil should be avoided. Such being the case, efforts were made to develop a gear hobbing process dispensing with cutting oil (energy efficient hobbing machine). An energy efficient hobbing machine was designed and fabricated and technical problems to solve toward practical application were studied. For the realization of an oil-free machine, a belt was employed for driving the hobbing shaft, grease was fed for bearing lubrication, a servo was used for elevation, and a linear guide was used for the support arm, and these eliminated sliding surfaces requiring lubrication. The hob and the work were cooled by air. The experimentally constructed machine was evaluated for oil-free sliding surface endurance, prevention of scratches from occurring on teeth, thermal deformation and displacement, hob wear, and the energy saving effect. The amount of electric power that the new machine consumes is found to be 30% less than that consumed by the conventional type. (NEDO)

    For the coal liquefaction, improvement of liquefaction conditions and increase of liquefied oil yield are expected by suppressing the recombination through rapid stabilization of pyrolytic radicals which are formed at the initial stage of liquefaction. Two-stage liquefaction combining prethermal treatment and liquefaction was performed under various conditions, to investigate the effects of reaction conditions on the yields and properties of products as well as to increase liquefied oil yield. Consequently, it was found that the catalyst contributes greatly to the hydrogen transfer to coal at the prethermal treatment. High yield of n-hexane soluble fraction with products having low condensation degree could be obtained by combining the prethermal treatment in the presence of hydrogen and catalyst with the concentration of slurry after the treatment. This was considered to be caused by the synergetic effect between the improvement of liquefaction by suppressing polymerization/condensation at the initial stage of reaction through the prethermal treatment and the effective hydrogen transfer accompanied with the improvement of contact efficiency of coal/catalyst by the concentration of slurry at the stage of liquefaction. 4 refs., 8 figs.

    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)

It will take development cost of eight to nine billion yen with the period of nine years for the development. Majority of the technologies required for developing the future 600-MW class generator can be demonstrated. The AC superconductor device sub-committee has investigated design examples, clarified the specification requirements, and investigated and studied the development measures. The oxide superconductor sub-committee has investigated and studied making wires and conductors, and device application feasibility, but has not reached the stage of presenting specific research and development methods. The practical application strategy sub-committee has also not been able to present a collective measure because of difficulty of making future prospect on the electric power business. (NEDO)

    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.

    For the development of working conditions fit for aged people and devices for them to operate, their visual function and behavioral characteristics are measured and analyzed. In the study of visual functions, 50 people from local cities and regions and another 50 from Osaka and its neighboring cities are subjected to measurement regarding visual acuity required in daily life, color discrimination, dark adaptation, glare, and the like. In the study of performing characteristics, 500 people are subjected to measurement regarding the scope of movement of upper limbs, their reach, and skillfulness with which the people can move fingers. When brightness, luminance, and contrast are caused to change relative to letters and background, aging is found to exert a great influence on the ease of reading, dark adaptation, and glare. As for the upper limb work range and reachability and the skillfulness in finger movement, it is found that aging narrows down the tolerant work area, lowers the working pace, and greatly affects skillfulness depending on the device operating method, all these disclosing actualities of difference attributable to age and sex. Concerning the device operating position and the ease of device operating force application, new measuring and evaluating methods are worked out, and correlations between the contents of operation and the operating position are seized.

    As for fuel cells, which are expected as a new clean energy, the R and D are being proceeded with in various fields of the world, but the standardization has not been made both in Japan and abroad. In Japan, the situation is that the information on technical terms, indication method, performance test method, and environment/safety test methods of the phosphorous acid fuel cell power generation is publicly spread. In relation to the international promotion of fuel cells to be predicted, it is necessary to internationally standardize cells themselves which are a key component of fuel cell power generation facilities. Phosphorous acid fuel cells are expected of the earliest commercialization of all, but the common test method to evaluate life characteristics of the cell stack has not been established yet. In the R and D, for the purpose of internationally standardizing test methods to evaluate life characteristics of the cell stack, a study on the acceleration life test method of phosphoric acid fuel cells was conducted in terms of the technical trend, data, standard, etc. A plan was prepared on general rules of the method to test acceleration life at the cell reaction part of the small cell, and activities also were started for setting up a technical committee for the fuel cell power system in President`s Advisory Committee on Future Technology. 29 figs., 20 tabs.

    This report reports the fiscal 1998 R and D result of Femtosecond Technology Research Association (FESTA) supported by NEDO. For creation of industrial basic technologies supporting the advanced information society in the 21st century, ultra-high speed electronics technology including new functions beyond the speed limit of conventional electronics technologies is indispensable. From such viewpoint, this R and D aims at establishment of the basic technology controlling conditions of beams and electrons in a femtosecond (10{sup -15}-10{sup -12} seconds) region. In development of the titled system, this R and D aims at generation of high-intensity X-ray pulse by interaction between femtosecond light pulse and high-density electron beam pulse, and development of measurement technology (non- stop inspection) of high-speed moving objects using such X- ray pulse. In fiscal 1998, this project succeeded in time stabilization of laser oscillators at a 100fs level and generation of low-emittance electron beam pulse through development of ultra-short pulse synchronization, laser stabilization and electron beam pulse generation technologies.

    As experimental studies on the international standardization of immunochemical measurement of chemical substances, the two studies were conducted: a study using thiobencarb, etc. as model and a study using flutolanil as model. In the former, for thiobencarb, 2,4,5-T, myclobutanil, and methoprene, a series of the standard measurement protocol was set up of the extraction from unpolished rice and wheat using methanol, pretreatment after the extraction, and measurement by the direct C-ELISA method. In the latter, the study from the pretreatment method of specimens to the measurement was made to measure flutolanil and mepronil in grain and water/soil in the environment by the immunochemical method. The standard measuring method was established by the addition recovery test and by the confirmation obtained in the GC-MS method. As to the environmental origin interference in the immunochemical measuring system of imazalil, the result was obtained which suggests that the interference affects both the antigen-antibody reaction and the enzyme reaction. 11 refs., 94 figs., 35 tabs.
