Outlined herein are experimental results with a water hammer pump. It is a unique pump in that it depends only on potential energy of water to pump-up water. Water flows downwards from a reservoir at a high position into the pump , and is released from the exhaust valve. When velocity of water flowing in the pipe reaches a certain level, hydraulic force exceeds gravity of the exhaust valve to rapidly closes it, which is accompanied by rapid increase in pressure in the pump. High-pressure water flows into the air chamber, after pushing up the lifting valve, to compress air in the chamber. The lifting valve is closed, when pressure in the air chamber exceeds that in the pump, to pump up water in the chamber through the lifting pipe. Closure of the lifting valve produces a negative pressure within the pump, which, together with gravity of the exhaust valve, opens the valve again. The pump lifts water at 1.64l/min under the conditions of head: 3m and lift: 6m at an efficiency of 48.1%. 1 ref., 4 fig., 2 tab.

The interaction force induced to hull by steering is important for prediction of control performance of ships. The control interaction force coefficient dependent on the steering has been investigated through the rudder angle tests using three small model ships with a length of 2.5 m, i.e., mathematical type of ship, cargo type of ship, and tanker type of ship. The interaction forces acting on the hull, propeller, and rudder were determined by measuring the lateral force as well as the forward force of the hydrodynamic forces acting on the rudder. These forces were compared with the theoretically calculated values. Prior to the rudder angle tests, the self propulsion factor and the number of revolution of propeller were determined from the results of the open water tests, resistance tests, and self propulsion tests by the changing load method. The rudder angle tests were conducted under this number of revolution of propeller as a standard condition, and under those increasing and decreasing by 15%. Consequently, the interaction forces determined from the rudder angle tests agreed well with those determined from the other tests. When comparing the control hydrodynamic forces determined from the tests with those theoretically calculated, a similar trend was observed. Effectiveness of the theoretical model was confirmed. 4 refs., 14 figs., 3 tabs.

This R and D project is for the preliminary studies on development of the following 4 types of techniques for developing resources from gas-hydrates (GH): (1) gas-hydrate exploration, (2) excavation techniques, (3) methods for assessing environmental impacts, and (4) gas hydrate handling systems. The FY 1988 R and D results are described. For gas-hydrate exploration, the methods for analyzing inorganic ions and trace quantities of elements, which are necessary for accurately estimating the offshore GH around Japan, are established; and case studies are conducted for methods of predicting GH deposit forming mechanisms, and stability fields of GH, based on terrestrial heat flow and seismic data. For excavation techniques, GH decomposition rate is analyzed using a laboratory system which reproduces conditions of excavation of GH layers. For methods for assessing environmental impacts, a geo-hazard predicting model is established, to study ground displacement and gas leakage sensing systems and data transmission systems to cope with the hazards. For gas hydrate handling systems, an overall system is studied, and storage and transportation systems are outlined. (NEDO)

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.

Hydrogenolysis of different rank coals as Taiheiyo coal (75.7C%) and Pittston coal (85.4C%) were conducted in the presence of four kinds of catalysts (CuCrO4, Fe2O3+S, MoO3-TiO2 and MoS3-Al2O3) with an addition of tetralin as vehicle. The variation in viscosity in every reaction system was traced in the initial stage of the reaction by a torque meter attached to an autoclave. As a result, in every system, the torque decreased in the initial stage of temperature rise because of reduction of a solvent viscosity. The torque subsequently increased with temperature indicating two peaks before the following gradual decrease. In Taiheiyo coal, both peaks were low, and its coal conversion was more than 85%, while in Pittston coal, both peaks were sharp and high, and both subsequent torque reduction and coal conversion were smaller than those of Taiheiyo coal. 5 refs., 10 figs., 2 tabs.

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.

Study was made on application of a hydrogen engine to series hybrid electric vehicle (SHEV). Power of 20kW (for steady driving of a vehicle of 1t in total weight on flat road surface at 100km/h), and NOx emission concentration equivalent to that of EZEV (equivalent zero emission vehicle) were used as target performance. One of the merits of using a hydrogen engine for HEV is that conventional high-reliability gasoline engines can be used as hydrogen engines only by a bit of modification. A modified conventional 4-cylinder 4-cycle gasoline engine was used for this study. Hydrogen gas was continuously supplied through an intake manifold for premixed combustion by spark ignition. Brake thermal efficiency was improved from 30.5% to 35.5% by use of a high compression ratio and reduction of friction loss. NOx emission concentration could be controlled within 10ppm by ultra-lean combustion even at excess air ratios over 2.5. Both high efficiency and low emission were achieved at the same time around 3000rpm in engine revolution. 4 refs., 12 figs., 1 tab.

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

After the shock of Hyogoken Nanbu Earthquake in 1995, protection against level 2 earthquake becomes important subject for civil structures. Subsequently plastic design methods for steel piers have been studied and rapidly introduced. The authors developed a method to evaluate the earthquake resisting performance of a steel pier with a single mass model. This model is useful for design because of its simplicity but on the other hand it can not consider the effects of piers` interaction in space. To include this effect in an analysis a simple 3 dimensional calculation model of box-column pier is developed. (author)

The paper made an investigational study of the data of a wide range which seems to be related to the use of hydrogen as automobile use fuel. The advantage is that the exhaust can almost be non-pollutant. The engine performance can be on the same level as that of the present gasoline engine or can be improved. The reasons are that the compression rate is heightened and that automobile can be driven at lean mixture rate. As to weak points, the volume and weight increase when it is loaded on vehicle. The cost of hydrogen is higher than that of petroleum. The problems to be quickly solved are as follows. Improvement of the combustion method: a wide range of development not only the electric ignition method, but the diesel method, and the basic study for it. It is necessary to establish the basis for a method to connect the storage method and engine. It is also necessary to comprehensively review rules related to safety. For the future, the conversion to artificial fuel is indispensable, and hydrogen has the most characteristics as energy medium. The problem is much larger sizes of fuel tank and pump, but there will be a possibility of producing a new technology together with the hydrogen production technology. The fundamental research should be promoted without any hesitation. (translated by NEDO)

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.

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

The 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.

In the use of hydrogen as fuel, there is the problem on NOx emission. The amount of NOx emission is not as much as in the use of coal or oil, but is more than in the use of natural gas or town gas. However, it can be said that hydrogen is an ideal fuel if considered that it does not emit other air pollutants such as CO, HC and soot/dust which are usually associated with hydrocarbon base gas fuels, and also that hydrogen forms a circulation system which is ecologically sound. The flame of hydrogen is non-luminous, but the flame temperature is high. The formation of NOx depends strongly upon the flame temperature, and therefore, in the design of hydrogen burner, it is necessary to well mix it with air and to avoid the production of the local high temperature region. Further, when using hydrogen to large boiler, the combustion technology to control NOx reduction is needed. About the hydrogen flame, the matter to be noticed is an experimental result that NOx reduction was observed by adding trace ammonia to hydrogen gas. If this method can be successful, NOx can be reduced with no increase in fuel consumption. It leads to hydrogen's reaching a position of clean energy. (NEDO)

In order to clarify problems involved in application of Weibull probability distribution used for estimation of power production by a large wind turbine to a small wind turbine, and solutions thereof, the estimated results are compared with the observed ones. The conventional estimation method, when applied to a small wind turbine, tends to overestimate production of power, because of overestimated production in a high wind velocity range which occurs less frequently. Estimation of power produced by a wind turbine is based on working wind velocity range, determined from the furling mechanism for the power generation characteristics of the wind turbine concerned. In the case of a small wind turbine, on the other hand, better estimates are obtained from the working wind velocity range in which Weibull wind velocity distribution is used to determine probability of occurrence. For wind turbines working at low to medium wind velocities, such as Savonius wind turbine, the estimates are in fairly good agreement with the observed results, by which is meant that the conventional estimation method aided by Weibull distribution can be directly applicable to small wind turbines. 4 refs., 3 figs., 3 tabs.

This research is conducted to search study themes of chemistry expected towards the 21st century. The complex compound in the fundamental chemistry field and the bio-medical materials in the applied chemistry field are taken up. Bio-medical materials are used for the restoration, rehabilitation, and treatment of the organ and the improvement of its functions. For implants such as hearts, anti-thrombin and anti-calcium precipitation effects and high endurance are required. In this field, special copolymers and bio-membrane-emulating surfaces are studied. For artificial organs, hybrid type materials combining cells, and physiologically active and artificial materials are also studied. There are studies on the missile therapy of drugs and DDS (drug delivery system). The complex compounds contain metallic elements, such as Fe, Mn, Co and Cu, and groups known as ligands which combine these metal elements. They can have a variety of stereo-structures and physical properties. They also exhibit a diversity of functions including electron donor bonding, molecular recognition, chemical substitution, and pharmaceutical activity. These features open up a promising potential for their prospective use as physiologically active substances, cancerostats, new materials, artificial photosynthesis, memory elements, and complex catalysts. 88 refs., 35 figs., 6 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.

This paper summarizes problems in utilization of solar energy, their solutions, features, the currently achieved results, and prospects. With regard to water decomposition using semiconductors, simultaneous generation of hydrogen and oxygen has already been achieved, and there is high possibility of raising the efficiency by improving catalysts. Water decomposition using metal complexes has acceleration of charge isolation as the largest problem, whose prospect of solution is not necessarily bright at the present time. Photo-catalytic reaction is a field to be discussed as one means of developing a new synthesizing method from the viewpoint of organic synthetic chemistry. Conversion into electric energy that uses a photovoltaic process has high efficiency, and is a field to be noted. In photo-energy conversion by means of photo-synthesis, living organisms performing hydrogen production at high efficiency have been discovered. Important studies include the studies in terms of chemical engineering using these living organisms, improvement of breeds by gene manipulations, and studies that utilize living organisms or part of the constituting components.

Estimation of the maneuvering performance of ships is very important from the viewpoint of safe navigation. Using three types of VLCCs (SR221A, B, C) with locally different stern frame lines as computational models, the estimation method of hull hydrodynamic force in turning motion was studied theoretically taking frame line shapes into account. The unstable behavior of courses was also studied using linear differential coefficients obtained from the estimation result on hull hydrodynamic force in oblique navigation and turning motion. As a result, the estimation result on hull hydrodynamic force was slightly different quantitatively from model test results in a range of large drift angle or turning angular velocity, while that was relatively well agreed with test results in a range of small such angle and velocity. As the study result on the unstable behavior of courses by using linear differential coefficients obtained from the estimation result on hull hydrodynamic force, determination of a course stability was possible by considering local difference in hull shape. 4 refs., 8 figs., 1 tab.

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.

A discussion was given on the fundamental properties of mortar made from cement mixed with silica fume. Four kinds of silica fumes with different particle size distributions were used. The following results were obtained: distribution of pores in mortar admixed with silica fume shifts to the smaller radius side; while the admixture increases the compression strength in mortar, the increasing trend varies depending on the kinds of silica fumes; this is thought to be caused from the difference in pozzolan activity between silica fumes; and the strength increase is caused by densification of the structure due to the pozzolan reaction that is generated after hydration, or in other words, decrease in the pore volume. The applicability of the mortar was investigated as a filling mortar to fill up clearances between wastes. It was found that the filling performance can be controlled by mixing silica fume at an adequate level and adjusting the viscosity. The diffusion coefficient for the admixed concrete is smaller by 30% to one digit than that for the ordinary concrete. High-performance water stopping concrete of 0.11 {times} 10{sup 4}cm {sup 2}/s at maximum was obtained. The concrete can be regarded as a material having superb filling and water stopping performances. 6 refs., 4 figs., 5 tabs.

This study intends to identify the visual confusion in spatial views by the routine human conveption of regularity and disorder, and elucidate physical factors that cause the disorder and regularity in street views. The disorder factors include the additions annexed to the view afterwards, and the regularity factors include those flat objects that decide the pattern of a view. Many factors can be either disorder or reguarity factors according to their sizes, how they look, and how they are affected by surrounding objects. The disorder in a street view is approximately determined of its degree by such distribution patterns as the spread and convergence of the disorder factors. The disorder can be intensified stronger by the spread of the factors widely over an entire area or the existence of objects that give disorderly impressions, rather than by the number of disorder factors. The regularity is affected easily by the disorder factors, it being lowered by intensities of the disorder. The deciding factors for the disorder or regularity are the kinds of objects, how they are laid out and what they are surrounded with. The factors that govern the degrees of the disorder and regularity are how large the area they are distributed in, the number, how they look, and where they are positioned. 24 refs., 9 figs., 6 tabs.

The purpose of this project is to develop and demonstrate the utility of feedback type gait training equipment designed for the measurement and evaluation by a walking training of the aged or patient. As similar concepts of walking training, a locomotion in the water for the aged is applied in rehabilitation. Our development of this study established the system of a suspending mechanism which revolves around the prop, and a walking on the circular type force plate by the aged or patient. It is possible to detect a walking reaction force of several patients from force plate simultaneously. And then, the data from force plate makes feedback signal to put up the patient like a buoyancy in the water. Concerning the evaluations of walking pattern a step range, a hanging ratio and a walking speed, etc. are acquired for each patient by the acknowledgment base. This system is actively able to perform a walking training continuously compared with conventional passive gait equipment. (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.

A `laminated rubber tile` and a `shock absorbing holed-in anchor` were devised in connection with the apron of a dam for a hydroelectric power plant. As the result of a survey on the hydroelectric power plants, ten plus places were observed where a general kind of concrete was severely worn in the company territory; but, there were substantial number of rubber materials that had still been sound for over ten years after the installation. In spite of the soundness of the rubber tiles, however, it was observed that their anchor supports had been cut and separated. An abrasion comparison test of concrete and rubber materials revealed that the rubber materials were considerably superior in abrasion resistance. Various rubber tiles were tested for abrasion resistance, tear strength, tensile strength, impact strength, etc.; and methods for fixing rubber tiles were also tested such as a holed-in anchor, chemical anchor and adhesives. As a result, a laminated rubber tile was designed with its upper layer constituted of a rubber sold on the market and its lower layer of a fiber reinforced rubber also on the market, and so was a shock absorbing type holed-in anchor. 1 ref., 11 figs., 4 tabs.

A cement-based filler is one of the back filling materials used in radioactive wastes disposal facilities. This paper describes fundamental tests performed on a filling material as to its filling performance, water permeation characteristics, and adsorption property to cerium by using the normal cement mortar (SM) that uses the water-to-cement ratio of 40% and the silica fume mortar (SFM). Furthermore, model wastes were fabricated by using a filling mortar of about 1 m{sup 3} and a 200-liter drum, which were used for tests on the filling and water cut-off performances. The result of the fundamental tests revealed the following matters: all of the materials show good filling performance and adsorbability when an adequate amount of high-performance water reducing agent is mixed; and the diffusion coefficient of the SFM is less than one tenth of that for the SM, showing high water cut-off effect. It was made clear from the tests using simulated test pieces that the Lugeon test value and water permeation coefficient of the SFM is less than half of that for the SM, and high water cut-off effect can be obtained by using the SFM. 11 refs., 8 figs., 4 tabs.

Wind power now being used is mostly for power generation, and the power generating rotor is represented by the horizontal propeller type. The vertical type, such as Savonius rotor which uses drag force, may be used for special purposes. The Savonius rotor has been used for water pumping-up and ventilation for its characteristics of low rotational speed and high torque. The authors have proposed, based on the data collected by operating a wind mill of 10W, a method for reducing resistance by deflecting wind flowing onto the return bucket to augment drag force, in an attempt to make the system more functional. The Savonius rotor is equipped with a semi-cylindrical cover, and guide and side plates, to follow their effects. It is found that these plates work to augment power without needing expansion of sweeping area. 4 refs., 12 figs.

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

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

A study is being made on premixed lean diesel combustion (PREDIC) by means of early fuel injection in diesel engines. The PREDIC makes it possible to largely reduce NOx emission, but has such problems as ignition control and increase in THC and CO generation. In order to clarify the relationship between fuel spray characteristics in the PREDIC and properties of gas mixture and exhausts, the present study has investigated spread and internal structure of the spray by means of spray observation experiment using a pintle swirl nozzle. Based on the result therefrom, simulations were used to investigate effects of spatial dispersion characteristics of the spray on properties of the gas mixture and exhausts before ignition. The pintle swirl nozzle forms conical spray having an air layer inside the spray, where penetration is suppressed even under low atmospheric pressure. By forming hollow spray or solid spray in the conical spray, a possibility was indicated that equivalent ratio distribution of the gas mixture can be controlled and NO emission may be reduced. 8 refs., 12 figs., 1 tab.

Described herein are the results of the FY1994 research program for structural defects of silicon-based amorphous materials for solar cells. The study on light generation defects of the a-Si:H system and rejuvenation process by annealing establishes the effects of light irradiation time on changed neutral dangling bond density as a result of light irradiation at varying temperature of 77K, room temperature and 393K. The study on annealing to rejuvenate light generation defects of various types of a-Si-H systems establishes the activation energy distribution with respect to annealing to remove light-induced defects, showing that hydrogen affects the distribution of light-induced defects. The study on decaying process of light-induced ESR for undoped and N-doped a-Si:H systems observes the decaying process of light-induced ESR, after light is cut off, extending for a period of several seconds to several hours at 77K for the a-Si-H systems containing N in a range from 0 to 12at%. The other results presented are space distribution of neutral defects of light-irradiated a-Si-H systems, and rejuvenation process of light-induced spin for the a-Si(1-x)N(x):H composition. 6 figs.

The cause of unburned hydrocarbon emission in small DI diesel engines at light load was studied. An optically accessible engine which was enabled to visualize the squish area was used to investigate the behavior of spray, mixture distribution and so on. Based on these observations and engine tests, the factors such as the direct impingement of liquid phase fuel spray to the combustion chamber wall the unevenness of fuel spray among holes and spreading of the fuel droplets, mixture and flame to the squish area were supposed to be the cause of forming HC emission. 18 refs., 10 figs., 2 tabs.

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.

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.

Recently, a fault diagnostic expert system was prosperously developed as an objective of chemical plants and nuclear power plants. In this paper, a fault diagnostic method using modularized knowledge was proposed, a fault diagnostic system was constructed for an experimental plant, and the effectiveness of this method was clarified by carrying out a fault diagnostic experiment. The characteristics of the proposed fault diagnostic system were as follows: The necessary knowledge for diagnosing faults was made into each process element. Based on this method, the revision and addition of a knowledge base could be carried out in each element, and the design change of a plant could be flexibly corresponded by only changing the related part of the process flow graph. The estimated results were stored into the working memory, not only faults of an element in which faults resulted could be estimated, but also the fault propagating path could be clarified. 8 refs., 6 figs., 3 tabs.

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

This is aimed at making an investigational study on the hydrogen production from water by means of quinone compounds. The paper studied a preparation method in case of using n-TiO2 photosemiconductor and p-GaAs and Gap photosemiconductor to photoelectrode as catalysts of this reaction. The reaction from p-benzoquinone to p-hydroquinone by reaction with H2O were studied in terms of photochemical reaction, and light reaction/dark reaction of photosemiconductor electrode. As a result, it was found out that this reaction easily advances by the photochemical reaction by solar light, and also that it advances by the counter electrode Pt electrode reaction in the water electrolysis of n-TiO2 photosemiconductor electrode. The H2 production reaction from p-hydrogquinone was studied in terms of the photochemical reaction, photosemiconductor electrode reaction, and effects of the catalysis of electron transport of metal salts, methylviologen, etc. As a result, in the n-TiO2 photosemiconductor electrode reaction, H2 formation was not as great as it can be confirmed. However, it was found that p-hydroquinone can produce H2 under the existence of methylviologen or Fe salts. (NEDO)

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

Fracture behavior of Al2O3-TiO2 sprayed ceramic coating was investigated at low cutting speeds when using two dimensional cutting. Scanning electron microscope was used to observe the generation, development and propagation of cracks during cutting. Small cracks and fracture have been developed in the cutting groove along the cutting direction, and there has been many fractures in spray particles unit. In the initial stage of cutting, radiant cracks have developed on the sprayed coating, however, linear big cracks starting from the cutting edge towards the cutting direction, have developed. The cracks have developed along the grain boundary of coating component, and cracks progressed along the portion with weak bonding force. When the depth of the cut was under 5[mu]m, the cutting face has formed many microfractures, and the cutting has been very stable. It has been necessary to select the cutting conditions that do not cause big fracture, microcutting and so on, in order to achieve favorable surface condition with minor fractures. 8 refs., 13 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.

This paper reports on the present situation of the chemical use of hydrogen and oxygen, and the short-term, medium-term, and long-term forecast. The main usage of hydrogen is ammonia synthesis, petroleum refining, and methanol synthesis. In the usage of these three, there are factors of structural changes now and in future, and it is extremely difficult to predict the amount in a short term up to around 1980. In a medium term prediction, from the result of predicting the demand of ammonia, methanol and hydrodesulfurization, the total 1985 hydrogen demand is estimated at approximately 60 billion Nm{sup 3}, and approximately 67 billion Nm{sup 3} as the gross hydrogen demand. Further, judging from that synthetic protein, fuel use methanol, and reduced iron are estimated to reach a certain production size in and after 1985, new demand for hydrogen is expected to be approximately 100 billion Nm{sup 3} mostly including fuel use methanol. In a long term prediction, it is extremely hard to predict the demand because of various factors existing in Japan and abroad. As predicted in a medium term, the amount of chemical use of hydrogen is expected to increase more and more, even if calculating it only in the field of ammonia synthesis, petroleum refining, and methanol synthesis.

This paper describes an automatic trespassing supervisory system with ITV and picture processing (PP). The paper details an integrated control system and automatic supervision. The system functions to automatically detect a trespassing by means of PP, transfers items of information collected by sensors to a remote control center, and records relevant data. The operation principle consists of measurement of change in two or more images of moving bodies with binary value at a certain interval, determination on acceptability of the moving bodies represented by human characteristics, and identification of a trespasser. The system consists of an automatic supervisory device using PP and an automatic patrolling and searching device by means of sensor measurements. The supervisory device has images outputted from ITV and VTR processed by PP, host computer, and HD, and linked to an indication mechanism. According to the result of a site test at wireless transmission station of Kyushu Electric Power Company, the difference between measurement values collected by the searching device and those by the supervisory device was [plus minus]3% or less (other than EG output current), which is a useful value for verification. Although the basic technique has been established, practical use of the system still has some problems including performance improvement in picture processing. 37 refs., 38 figs., 18 tabs.

We have developed a high performance hydrogen storage alloy (MH alloy) suited to NiMH batteries for EV use. During the course of the development, the effects of alloy composition and structure (B/A ratio in AB{sub 5}) on cycle life and high-rate discharge of MH electrodes were investigated using mainly SEM, XRD, TEM analysis. It was found that Co content and B/A ratio (5.1/5) of MH alloy have significant effects on corrosion resistance and high-rate discharge at low temperature. Further, the surface treatments of MH alloy with weak acids and hydrophobic agents were effective for improving the initial activation and for depressing the cell internal pressure build-up.

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.

Equisetum was noted as a plant adaptable to stringent environment referred to as the water level varying part of a reservoir, and was used for afforestation trials. The afforestation trials were performed at the reservoir of Uryuu Dam No. 1 and the regulating reservoir of Moiwa Dam of Hokkaido Electric Power Company. Although the rate of water level variation is small at Uryuu Dam No. 1, it is necessary for Equisetum to withstand submergence and drought for an extended period of time. Moiwa Dam has high water level variation rate, but its water depth is small, and the reservoir is free of long-term submergence and drought. As a result of long-term observation from 1993 through 1997, Equisetum was found having grown well at lower altitude part with higher submergence frequency. It has grown favorably even in parts where submergence rate reaches about 80%. However, at higher altitude with submergence rate of 10% or lower, decrement trend was seen. At Moiwa Dam, Equisetum was all buried in accumulated sand and earth, revealing that such an environment is unsuitable for Equisetum as the one subject to effect of sand and earth that flow in during freshet.

Development is intended to be made on fundamental combustion control technologies applicable to high-performance industrial furnaces that can reduce energy consumption and respond to environment preservation requirements. With an intention to achieve reduction in combustion exhaust gases such as carbon dioxide and nitrogen oxides, fundamental studies will be made on factors to decide flame shapes as represented by high-temperature combustion and flame shape control by utilizing microgravity environment, and researches will be made on combustion systems. Devices required for the experiments were fabricated to evaluate critical combustion characteristics of flames in furnaces including industrial furnaces, analyze and evaluate flame control parameters, and study low-pollution combustion technologies. Experimental methods acquired by 1997 were used for the experiments under the microgravity environment. Evaluation experiments were performed on flame shape control technologies and flame radiation characteristics, and basic experiments on the low-pollution combustion technologies. With these experiments, elucidation of the combustion mechanisms was launched by analyzing and evaluating the acquired data. A flame experimenting device for high-temperature preheated air completed by fiscal 1997 was used to acquire such combustion characteristics data as NOx discharge characteristics when the high-temperature preheated air is used. Based on the result thereof, verification was carried out on simulation models. (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.

Mechanical properties and failure behavior of weft knitted fabric reinforced composites were studied. Aramid fiber was used as reinforcement (knitting fiber), and epoxy resin as matrix. Different tensions were applied to the weft knitted fabric in a course or wale direction to prepare 5 kinds of fiber reinforced composites with different densities of the knitted fabric, and tensile test pieces were thus provided by cutting each composite in a course or wale direction. As a result, the weft knitted fabric reinforced composite offered a dynamical anisotropy, and the tensile strength of the test pieces was higher in wale direction than course one. Fracture in a course direction occurred at the section with extreme low fiber content, while fracture in a wale direction occurred at a loop interlocking region due to stress concentration. The tensile strength was constant or increased in a course or wale direction by stretching the knitted fabric before molding, respectively. 21 refs., 15 figs., 2 tabs.

Described herein are the FY 2000 results of the research study on environmental information network formation. The Internet is experiencing an explosive increase in volume of information distributed therethrough. This is accompanied by increased problems related to information searches, information exchange security and information-reliability guarantees. First in demand are excellent portal sites, and second are sites that can be relied on to responsibly provide information. Cooperation with the real world off the Net is of particular importance, because the operating organizations, e.g., sites, will lose their raison deter, unless they clarify their unique abilities and characteristics under the tendencies towards broadened bands and ubiquity. The public sector, on the other hand, is highly reliable, accumulates a large volume of information, and has high network capacity. It has various functions, e.g., supporting the activities pertaining to ISO standards, and promoting the activities, e.g., those for educational programs, interdisciplinary exchanges by researchers, and matching of various organizations. The international cooperation for environmental information needs construction and operation of the networks, and construction of the infrastructures in the developing countries. If information becomes more ubiquitous, a chaotic sea of information will result. NEDO is strongly obliged to serve as the beacon, because it has established a huge volume of environment-related technologies, information, and networks. (NEDO)

To effectively utilize unused sea weeds having ingestion obstructing activities for feed, the treatment by oxygen added enzyme has been investigated. Undaria pinnatifida was pasted and solidified with agar, to prepare the standard feed. Individuals of Holiotis discus hannai Ino were bred in the cistern. Extracts from ten kinds of sea weed distributed in the Sanriku Coast were added to the feed, which were compared with the standard feed to determine the ingestion obstructing activities. A testing method using cellulose painted aluminum sheet was also employed. All of the extracts from sea weeds having the ingestion obstructing activities exhibited the strong phenol reactions. The sensitivity of individuals of Holiotis discus hannai Ino depended greatly on the derived species and the chemical structures of phenolic substances. The {alpha}-hydroxymuconic acid semialdehyde (HMS), an enzyme decomposition product of catechol, provided no ingestion obstructing activity, and showed a little ingestion accelerating activity. This was considered to become ingestible through the biodegradation of phenolic substances. The HMS, a decomposition product of catechol 2,3-oxygen added enzyme derived from the petroleum decomposition bacteria, was prospective as a highly functional compound synthesizing material. 10 refs., 34 figs., 10 tabs.

Study was made for grasping the basic data of CO2 fixation technology by seaweed. The photosynthesis under the sea, which is different from that on the land, is judged to be made by taking in HCO3[sup -] and converting it into CO2 inside the plant. Porphyra yezoensis which is seaweed is cultivated as comestible. With a rise in CO2 content, the growth in length of leaves was observed to be accelerated through ventilating Porphyra yezoensis with the three test types of air which respectively contained 350ppm (atmospheric CO2 content), 1000ppm and 1600ppm CO2. As a result of measuring the photosynthesis speed by the generated quantity of O2, it was heightened with a rise in dissolved inorganic carbonic acid content of the sea water. Measurement was also made of daily fluctuation in calcification speed by Corallina officinalis capable of calcification by ventilating it with 350ppm and 1600ppm CO2. In case of 1600ppm, the sedimentation of CaCO3 was prevented. In case of 350ppm, the sedimentation was quantitatively larger during the bright period than that during the dark period. The growth of Gracilaria gigas which is an agar material was compared by changing the above CO2 levels. In case of 1600ppm, the weight grew to 2.3 times in 20 days. 16 figs., 2 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.

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.

Kinds of ground materials, porosity, electrical resistivity of pores, degree of saturation, and content of clays are the factors affecting the electrical resistivity of soils. In addition to these factors, the electrical resistivity of soils around hot spring water and geothermal areas depends on the temperature due to fluctuation of cation mobility in the pore water with the temperature. In this paper, the temperature dependency of electrical resistivity of groundwater and soils is investigated by recognizing that of groundwater as that of pore water. As a result, it was found that the electrical resistivity of groundwater becomes lower as increasing the amount of dissolved cation, and that the temperature dependency of electrical resistivity is not significant because of the small mobility of cation. The electrical resistivity of soils was significantly affected by that of pore water, in which the mobility of cation was changed with temperature changes. Accordingly, the temperature dependency of electrical resistivity of soils has a similar tendency as that of groundwater. 5 refs., 9 figs., 2 tabs.

In Japan, there were some serious disasters in recent years. In 1991, Unzen-Fugendake erupted and more than 1,000 people were forced to take refuge from their houses. In 1993, Hokkaido-Nanseioki earthquake attacked the south-east area of Hokkaido and more than 3,557 houses were destroyed. In Japan, the government supplies the temporary housing to those who lost house from the natural disasters. The purpose of supplying temporary houses mentioned in the disaster relief law (established in 1947) prescribes the purpose of temporary housing that to rescue the poor who can not afford getting a shelter with their own funds. But actual condition of temporary housing is completely different. Government supplies temporary housing to all those who request temporary housing. The term of using temporary house tend to become longer. The regulation about temporary housing has not been yet up to dated. Many problems concerning about temporary housing originate in outdated regulation. The temporary housing have to be ranked in the part of restoration process from natural disaster. (author)

Design engineering and experimental study were made of precast PC clad connection. The clad connection method between the columns and beams is classified into bracket method, shearing key method, corbel method and reinforcing structure-jointing method, among which the corbel method is recommendable because of its simplicity without slip. The PC clad connection system is characterized by its possibility of structuring the continuous multi-rahmen structure, designing the highest strength concrete and easing the earthquake-proof design with a high toughness restoring force. The PC cable wiring method is classified into X-cross method and continuous method. The design of PC clad connection was experimentally proved by alternately loading the frame. Through the experiment, the interstory deformation angle, and stress behavior of the column and beam PC steel materials were made clear so that their destruction became able to be prevented. Also through the experiment, the interstory deformation angle and maximum column-shearing force were known at the yield point of beam, which had the frame-restoring force characteristics modeled by a trilinear elastoplastic type. 28 refs., 13 figs.

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

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.

In fiscal 1998, a target for the overall thermal efficiency of 105% was settled by testing a pilot plant where the element technology was integrated into the small once-through boiler, flue/smoke tube boiler, water tube boiler, etc. In fiscal 1999, the target of the overall thermal efficiency of boiler was reached by a pilot plant test to clarify combustion characteristics, heat transfer characteristics, environmental characteristics, etc. Further, effects of energy saving were increased by the adoption method of oxygen supply equipment. Concretely, an overall boiler efficiency of 105.73% exceeding the targeted value of 105% was achieved at a pilot plant of actual scale, by concentrating the results of each of the element technologies such as 'oxygen combustion,' 'condensation type flue gas heat exchanger,' 'high performance combustion control device,' and 'rapid rotating auxiliary machine.'

In the design of various floating offshore structures (FOS), the functionality, safety and amenity of FOSs were examined by estimating responses of FOSs to environmental external forces such as wave, wind and flow. In this paper, the estimation method of drag acting on the whole FOS was established by combining previous study results on hydrodynamic force acting on various bodies such as Reynolds number effect (RNE), 3-D effect (TDE) and interference effect (IE). This hydrodynamic force was also compared with that obtained from the experiment result on a FOS model for TLP to confirm the applicability of this estimation method. The estimation result on the drag coefficient in steady flow by considering RNE, TDE and IE well agreed with experimental one. The drag coefficient acting on FOSs in heaving could be estimated in practically sufficient accuracy by considering drag acting on not columns but only square columns. The estimation result on the drag coefficient acting on FOSs in surging by considering RNE, TDE and IE well agreed with experimental one. 12 refs., 10 figs., 1 tab.

The paper made an analysis of the heat island phenomenon in the Kanto area using 3-D numerical analysis models and a study on the effectiveness of the measures to prevent it. The models are composed of advection/diffusion models of heat/steam in the wind-velocity field and atmospheric air, heat diffusion models in the underground and undersea, and heat balance models on the ground surface and sea surface. In the calculation, a simulation was conducted of the case of taking the following three measures: the case where the exhaust heat was reduced 30% in the assumed typical day of summer; the case where the heat volume of buildings/trunk roads was reduced; the case where the evaporation efficiency of buildings/trunk roads was raised. The result of the study was as follows: The reduction effect of the exhaust heat is totally large, but precisely observing, some meshes contrarily showed rises in temperature in the suburbs. Also in the case of reducing the heat volume, the same phenomenon occurred, but the effect was large in the center of a city. It was found that the effect was unexpectedly large in the case of increasing the evaporation efficiency. 7 refs., 14 figs., 2 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.

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.

This report covers surveys of the latest technological trends in relation to the production, storage, and transportation of hydrogen as energy. Also included in the report are surveys of hydrogen, fuel cells, and wind energy centering about Europe. At the 4th World Hydrogen Energy Conference (Pasadena, U.S., June 1982), a number of essays were presented concerning the utilization of hydrogen, production of hydrogen, thermochemical processes, hybrid processes, photochemical processes, photo/thermochemical processes, other processes, fuel cells, metallic hydrides, etc. This report particularly describes in detail the trends of technologies involving the production of hydrogen by the electrolysis of water and by thermochemical processes. As for the recent trend of the metallic hydride technology, reports are made on the International Symposium on the Properties and Applications of Metal Hydrides (Toba, Japan, June 1982) and on Japan's research on the application of metallic hydrides. Concerning the trends in Europe of technologies relative to hydrogen, fuel cells, and wind energy, the results of the research group's on-site investigations are reported. (NEDO)

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.

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.

The effect of silica fume and ground blast furnace slag in concrete on the content of superplasticizer, and dynamic properties of hardened mortar with such admixtures were studied experimentally. Although the dependence of a flow value on the superplasticizer was dominated by kinds of superplasticizers, blast furnace slag enhanced the flow value resulting in a high fluidity. Adsorption of superplasticizers onto admixtures was dependent on kinds of superplasticizers, and adsorption onto blast furnace slag was 1.3-2 times that onto normal Portland cement (NPC). The compressive strength of mortar increased by mixing admixtures, while the bending strength was enhanced only by mixing silica fume. Mixing mortar was lower in dynamic elastic modulus than NPC mortar at the same compressive strength, and the velocity of supersonic wave in mortar was scarcely affected by mixing. 11 refs., 14 figs., 3 tabs.

Behaviors of care staffs and residents are surveyed in four nursing homes. The results of the analysis of the survey are as follows: The care staff`s activities are influenced not only by physical environment and also by the residents` activities. A single bed room is more effective than a multi-bed room for individual care. The small care unit is effective in building plan if the number of staffs is enough. The personal care activities which constitute the greater part of the care activities depend on the location of the residents. It is important to pay attention not only to arrange the common space but also how to use the common space. Spatial structure is required the consideration of the relative position of not only care rooms and resident rooms but also of care rooms and the space used by residents. 7 refs., 14 figs., 7 tabs.

The whole amount of hydrogen consumption for chemical industries all over the world is estimated to be 249.7 billion Nm{sup 3} in 1974, while 367.2 billion Nm{sup 3} in 1980 roughly under a bold assumption, based on 3 current big consumption fields of ammonia production, methanol production and petroleum refining, and some promising fields in the future such as reduced iron and synthetic protein. Consumption ratios for every field are probably 54.9% in ammonia production, 30% in petroleum refining, 9.5% in methanol production and 5.6% in others in 1974, and nearly similar in 1980. However, although there are various troubles, if a large amount of methanol is used as fuel in the future, and its production plan is promoted to satisfy the demand of methanol fuel, hydrogen consumption for methanol production will increase drastically. In the future, if the production process of hydrogen as secondary fuel is established, such hydrogen also will be used for various chemical industries naturally. Research was thus made on use of oxygen as byproduct inevitably. (NEDO)

The paper studied the engineering for activating areas using natural energy. 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.

In the paradigm that propelled polymer chemistry, there are involved the establishment of polymer concept, engineering plastics, regulation of higher ordered structure, and precision polymerization. The first two produced the polymer chemistry era in the 20th century. The regulation of higher ordered structure and the precision polymerization are the fundamental technologies supporting the polymer chemistry of the 21st century. The precision polymerization is a technology for regulating the stereospecificity, sequential structure, and molecular weight of polymers by regulating atoms and molecules and is referred to the following important techniques to be concrete. In the precision addition polymerization, stereospecific regulation and purification of active site to give living polymers are required while, in the precision condensation polymerization, regulation of condensation probability process to be secondary Marcov chain is necessary, as is the establishment of non-defect condensation condition avoiding high temperature deterioration and the like. In the biomimetic precision polymerization, key issues are the method of incorporating molecular recognition control and sequential structure control by living organs into an industrial process. If the higher ordered structure can be regulated by the precision polymerization, it is possible to obtain numerous high performance/high functional materials such as superconductors. (NEDO)

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.

In this paper, we propose the State Grouping scheme for coping with the problem of scaling up the Reinforcement Learning Algorithm to real, large size application. The grouping scheme is based on geographical and trial-error information, and is made up with state generating, state combining, state splitting, state forgetting procedures, with corresponding action selecting module and learning module. Also, we discuss the Labeling Based Evaluation scheme which can evaluate the opportunity of the state-action pair, therefore, use better experience to guide the exploration of the state-space effectively. Incorporating the Labeling Based Evaluation and State Grouping scheme into the Reinforcement Learning Algorithm, we get the approach that can generate organized state space for Reinforcement Learning, and do problem solving as well. We argue that the approach with this kind of ability is necessary for autonomous agent, namely, autonomous agent can not act depending on any pre-defined map, instead, it should search the environment as well as find the optimal problem solution autonomously and simultaneously. By solving the large state-size 3-DOF and 4-link manipulator problem, we show the efficiency of the proposed approach, i.e., the agent can achieve the optimal or sub-optimal path with less memory and less time. 14 refs., 11 figs., 3 tabs.

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)

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.

To clarify soot formation and oxidation process in diesel combustion, the natural emission of OH radical and the flame temperature were obtained in the combustion chamber of D.I. diesel engine. Further, soot were detected by LII (Laser Induced Incandescence) and LIS (Laser Induced Scattering) technique to assess the relative soot diameter and its number density. OH emission and flame temperature were compared with data of soot diameter and number- density. The results show that : (1) OH emission has relation to flame temperature. (2) OH emission arises latter than soot emission, because early soot at early combustion consume OH to oxidate. (3) As soon as it is ignited, soot particles are formed in the region of low temperature. 6 refs., 7 figs., 2 tabs.

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.

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

In order to perform efficient and safe controlled blasting, attaining sufficient detonation from explosive is important. Therefore, a mechanism of detonation in a bore hole was studied. Two detonation phenomenon measuring methods were established: one is a continuous detonation speed measuring method by using a resistance wire probe, and another is a detonation mark observing and evaluating method using aluminum and metallic lead plates. Assuming delay blastings in multiple bore holes used practically, discussions were given on detonation phenomena of explosives under pressurized condition. Under dynamic pressure condition, size of the pressurization and delay time of the detonations affected largely the detonation. Discussions were given on blasting effect and safety according to difference in forward initiation and reverse initiation. The reverse initiation method was verified to have excellent blasting effect, maintain good face conditions, and assure safety against inflammable gases. A precision initiation method was developed, which can control the initiation time of a detonator more precisely. The initiation accuracy is more than 1000 times greater than the ordinary instantaneously detonating electric detonator. The precision control of the initiation time proved to develop greater crack propagation. Vibration and stone scattering were also controlled. This paper also describes application of the method to a rock elastic wave exploration technique. 136 refs., 99 figs., 13 tabs.

Temperature and humidity characteristics and condensation within walls under heating and humidification were studied experimentally in winter using two test houses of conventional and ventilated structures. The absolute humidity in conventional one fluctuated depending on temperature gradient, water flux due to humidification and water adsorption onto glass wool, and accumulated water increased with humidification. That in ventilated one was also affected by dehumidification through ventilation layers. Under heating and humidification, the absolute humidity increased depending on temperature rise and water flux within walls. In conventional one, condensation was frequently observed on felt in walls and others because of accumulated humidity, while in ventilated one, humidity was kept lower within walls even under heating, because humidity in walls was discharged through ventilation layers. Condensation was also scarcely observed on waterproof moisture-permeable sheets in walls and others. 3 refs ., 39 figs 1., tab.

This paper discusses the heat transfer analysis in a furnace for LPG reforming to produce gas enriched hydrogen. The three-dimensional combined radiative and convective heat transfer processes in a furnace for LPG reforming is simulated by introducing the radiosity concept into the radiative heat ray method for an accurate radiative heat transfer analysis. Together with an analysis of the chemical reaction in the reactor tubes of the furnace, the heat transfer simulation gives the three-dimensional profile of the combustion gas temperature in the furnace, the tube-surface heat-flux distribution and the composition of the reformed gas. From the results of the analysis, it was clarified that increasing the jet angle of the heating burner raises the gas temperature and the tube surface heat flux near the burner entrance, and that the flame shape is the most important factor for deciding the heat flux distribution of the tube surface because the heat transfer effect by flame radiation is much more than that by convection of the combustion gas. 18 refs., 9 figs., 2 tabs.

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.

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.

This paper presents the results of performance tests of various kinds of adsorbents by static and dynamic adsorption methods to select the optimum deodorant (adsorbent) for ammonia gas (NH3). In the performance test of the static adsorption method, the amounts of NH3 adsorbed by 21 kinds of adsorbents including physical and chemical adsorbents were measure. The amounts adsorbed physical adsorbent No. 6, chemical adsorbents Nos. 18, 19 and 20 which showed higher adsorption ability were 0.0160g/g, 0.0284g/g, 0.0250g/g, and 0.0249g/g respectively at 30degC under equilibrium pressure of 50 mmHg. All of the adsorbent showed in Freundlich`s adsorption isotherm for NH3. Although the correlation between specific area, pore volume, mean pore radius, pH each adsorbent and the amount of adsorbed were tried, the correlation between the pH and the amount of NH3 adsorbed was significant. This suggests that the pH is a proper criterion for selection for adsorbents. The performance test of the dynamic adsorption method, was conducted for adsorbents Nos. 6, 18, 19 and 20 above-mentioned. The 10% breakthrough time was compared as the performance index. The breakthrough time of the adsorbent which the amount adsorbed was large was long but the breakthrough time was not proportional to the amount adsorbed. These results suggest that the performance test only by the static adsorption method is insufficient and that the breakthrough time test by the dynamic adsorption method is essential. 13 refs., 10 figs., 4 tabs.

This report summarizes the fiscal 1999 research cooperation project result on coal liquefaction technology. Cooperative FS was made on coal liquefaction technology of Indonesian coal as petroleum substituting energy. To obtain the basic data necessary for the FS, study was made on the applicability of Indonesian natural minerals as catalytic materials. Promising low-cost abundant Soroako Limonite ore showed a high catalytic activity for liquefaction reaction of Banko coal, and an excellent grindability. Improved BCL process including hydrogenation process was promising for production of high-quality coal liquid superior in storage stability with less nitrogen and sulfur contents. Survey was made on the general conditions of Tanjung Enim area including South Banko coal field concerned, and the geological features and coal seam of South Banko coal field which is composed of 3 seams including coal deposits of 6.35 hundred million tons. To study the marketability of coal liquid, survey was made on the current situation of oil, oil product standards, and blendability of coal liquid. Hydrogen for the liquefaction process can be obtained by coal gasification. (NEDO)

Studies have been made on preparing criteria for the safety assuring technologies for hydrogen energy total systems. The outline of the technological guideline for hydrogen manufacturing processes in the high temperature and pressure water decomposition method is the same as that in the normal pressure water decomposition method. However, its high temperature and pressure environment can cause new safety problems. Considerations should be given on, for example, material problems in structural materials and insulation materials including electrodes and membranes, introduction of gas-liquid separation and pressure balancing devices, problems in electrolyte circulation, and safety problems that may occur because of generation of hydrogen and oxygen under high temperature and pressure conditions. This paper summarizes these matters by surveying literature data. In order to provide basic information to prepare criteria for safety assuring technologies for the gaseous hydrogen liquefaction process, surveys and studies were made based on different items of technological information and experimental study results. Safety assuring technologies were discussed on metal hydrides (promising means for storing hydrogen). Powder is used to enhance hydrogen absorbing performance, whereas the metal hydrides are pulverized as a result of repetition of absorption and discharge of hydrogen. This paper describes also metal dust explosion disaster and its risk of occurrence. (NEDO)

The phenomena that clay or mud is carried away by waves or currents and deposited in approach channels and harbors are called siltation, and hinder often seriously the navigation of vessels and their arrival at as well as departure from wharves, etc.. In this paper, the hydraulic mechanism of siltation in harbors and approach channels in the sea area is chozen in particular, and waves and currents as the external force governing the travel of bottom mud, the properties of sunken mud, the supply source of sunken mud in approach channels, and grasping of the mud sinking mechanism as well as countermeasures against mud sinking are stated mainly centering around the results obtained from the in situ observations at Kumamoto Port and Banjarmasin Port and their mathematical calculations. The bottom mud traveling mechanism has been accepted as a study subject respectively from such wide viewpoints as river engineering, agriculture, environmental engineering, sanitary engineering, chemical engineering and mechanical engineering, and in addition, it has been under study by coastal engineering. Siltation under the wave actions is still in the state of research even in advanced countries in America and Europe. The siltation research in Japan has a short history, but this is the field which must be coped with positively. 19 refs., 17 figs.

Wastewater reuse can be considered as a type of water resource development which is expected to improve the aquatic environment, as well as the stability and reliability of municipal water supply systems. To this extent, wastewater reuse has been taken into account in the planning of water supply systems in several Japanese cities. However, to date the effect of wastewater reuse on water supply system stabilization has not been discussed quantitatively, and the relation between waster water reuse rate and water supply system stability has not been analyzed. In this study, a stochastic model has been presented to evaluate the stability of water supply systems with optimal wastewater reuse rate. Some theoretical analyses and numerical studies were performed, and all of the results have shown that the model is reliable for not only basic studies on water supply system stability, but also for practical use as well. 5 refs., 5 figs., 3 tabs.

This report deals with heat transfer in the melting process of crushed ice filling in a ice/water heat storage container. Volumetric heat transfer rate and melting end-time are measured when rectangular-type, small-stone-type and particle-type ice in the container are melted by circulation hot water. Melting end-time of small-stone-type ice is the shortest and that of particle-type ice is the latest. Volumetric heat transfer rate of small-stone-type ice and rectangular-type ice is larger than that of particle-type ice. The flow rate of circulation hot water throwing in container through a inlet pipe influences remarkably on heat transfer rate. 4 refs., 10 figs.

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.

This paper describes the research achievements in the Sunshine Project in fiscal 1992 in studies on a direct gasification catalyst. The paper summarizes the points where the catalyst research has reached to date. The catalyst surface effective for hydrogenation is the metal surface that can dissociate hydrogen. However, metals having large adsorption heat against hydrogen do not show the activity greatly because these metals are difficult of desorbing hydrogen having high dissociating activity. The coal liquefaction system has the surface oxidized by water content, wherein hydrogen dissociation cannot be expected, and sulfides are suitable. When a sulfide catalyst contacts hydrogen, the catalyst itself is desulfurized, producing H{sub 2}S and becomes a low-order sulfide. When atmospheric H{sub 2}S contacts this sulfide, it dissociates into HS and H, and this H behaves as active hydrogen. However, the liquefaction activity can be recognized even in a sulfuric acid type catalyst containing no sulfide whatsoever, wherein the H{sub 2}S partial pressure in the reaction system becomes extremely low. This fact means that the active hydrogen is not necessarily generated by the dissociation of H{sub 2}S. There is no other way but to think that hydrogen is dissociated directly without going through H{sub 2}S. If this is true, it provides a new guideline in developing and designing the future catalysts. (NEDO)

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

The paper studies the measures for reduction of environmental load of CO2 from the standpoint of chemical technology. As for methanol synthesis from CO2, accelerating of the reaction using Cu base compound catalyst is reported. Also, CO2 is methanated at high speed by low temperature waste heat using Ni-La2O3-Ru catalyst. Discussions are given on the subject for development of catalyst reaction relating to hydrogen production technology by methane reforming reaction using steam or CO2. Synthesis of polymetric materials by use of CO2 is also described. The paper mentions that it is indispensable to design high-function electrode and elucidate the reaction mechanism of electrochemical CO2 reduction for electrochemical and photochemical CO2 reduction measures. Moreover, in case of using solar energy, it is required to study photovoltaic excitation process in semiconductor electrode/ electrolyte solution interface. For production of hydrogen from CO2 by photosynthetic organisms and solar energy, the problem is control of inhibiting effect of oxygen combinedly produced. Described are production of polyhydroxy butyric acid and biodegradable polymer from CO2 and hydrogen by bacteria, and CO2 fixation imitating the enzyme reaction. 267 refs., 79 figs., 32 tabs.

Surveys and studies were performed on chemical utilization of hydrogen regarding its status of development and utilization inside and outside the country, as well as its future prospect. This paper describes chemical utilization of hydrogen in ammonia, methanol, petroleum refining and other industries as the existing fields. It also describes chemical utilization of oxygen in iron and steel, chemical and other industries. It describes methanol as a pollution-free auxiliary fuel for electric power plants as a new type of hydrogen application. Acetic acid made by using the Monsanto method which carbonylate methanol is drawing attention in terms of economy, and is in the phase of discussing commercialization. Synthesizing ethylene glycol from carbon monoxide and hydrogen may be conceived economically. Methanol for synthesized protein depends on the possibility of future development. In the iron and steel industry, electric furnace steel makers are planning production of reduced iron, where the direct reduction process using hydrogen is considered as a complementary process, including countermeasures for scrap iron. This paper estimates hydrogen amount as a raw material for ammonia to remove NOx by using the ammonia reduction process. It also describes possibility of other types of utilization. (NEDO)

This report describes an interim evaluation method and a concrete evaluation method for projects promoted by the Agency of Industrial Science and Technology, and NEDO. As a result of the survey, a method of highly practical interim evaluation, concrete evaluation items, and evaluation criteria have been proposed by assuming that the projects are evaluated by the project evaluation department independent of the project promotion department. Long-term issues for constructing the evaluation system are also described. It is the most essential for the evaluation to fulfill the function of effective promotion of the following projects. It is also indispensable for the evaluation method and issues proposed in this report to communicate closely to project promoters and researchers, and to reassess the projects continuously. Continuous consideration for the feedback of evaluation process and the improvement of evaluation are significant for the long-term construction of system. 21 refs., 9 figs., 23 tabs.

To evaluate the risk during longevity of reinforced concrete structure subjected to earthquake motions, called lifetime risk, damage and safety were estimated by means of the earthquake risk analysis and earthquake response analysis. For the earthquake risk analysis, historical earthquake data with relatively low accuracy were efficiently taken into account, to determine the annual mean generation probability against the earthquake motion strength in ten main cities. A new damage index with load hysteresis was defined as an anti-earthquake evaluation index where accumulative damage is taken into consideration. Assuming that the damage transits from `certain state` to `certain state` every time the earthquake motion generates at the noticeable place, damage transition matrix expressing transition probability was calculated by using the results of earthquake risk analysis and the accumulative damage index. The lifetime risk was calculated from the damage transition matrix and the earthquake motion generation probability, to evaluate the safety. 21 refs., 10 figs., 8 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.

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

The Hyogoken-nanbu earthquake in 1995 was a local earthquake that has hit directly a large urban area, having caused damages the greatest since the War mainly in the city of Kobe. The present study has noticed the areas of Sumiyoshi, Nada Ward, Kobe City and Nanbu, Nishinomiya City where damages show different distribution; elucidated the characteristics of earthquake ground motion based on microtremor measurements; and discussed the relation thereof with the earthquake damage distribution. It was verified that microtremors and seismic motions are in rough agreement in the Sumiyoshi area, by comparing and discussing the spectrum ratio between the microtremors and the seismic motions. No correspondence was recognized in the Sumiyoshi area between distribution of the average microtremor spectrum ratio with cycles of 0.2 to 0.8 second and distribution of damages caused by the Hyogoken-nanbu earthquake. The ground characteristics evaluation alone is insufficient to explain distribution of the damages in a relatively wide range in the city of Nishinomiya, for which effects of distance decay should be taken into consideration. 6 refs., 7 figs.

This paper reports the achievements in the following study items: (1) studies on the AFMT method, (2) observation of heat dissipation by using infrared thermal images, (3) evaluation on the annular topographic pattern in the Hachimantai area identified from the Landsat satellite images, (4) studies on the Tamagawa welded pyroclastic rocks, (5) studies on minerals transformed from the Tamagawa welded pyroclastic rocks, and (6) a method to analyze ground temperature data by using graphic display. Items 2 and 6 in the studies are on the heat balance method, and Item 3 is on remote sensing. Items 4 and 5 were performed as the study on geologic thermometry. In Item 1, a prototype AFMT method exploration device was fabricated, and field experiments were performed in the Onuma area in the Hachimantai wide-area geothermal experiment field. The experiment placed importance on finding problems in transmission and reception of signals from an artificially fluctuating magnetic field, whose result was found greatly contributive to understanding the physical phenomena. However, it was not possible to reach a level to analyze geological structures from the data. In Item 2, simple meteorological observation was performed on ground surface temperature distribution by using an infrared radiation thermometer of remote sensing type. Development was made on a method to measure natural heat dissipation amount from heat balance on the ground surface. (NEDO)

The paper outlines results of elementary study on the coal direct-use iron-making process and how to tackle with it in future. In the process coal and iron ores are used directly without prior treatments like coking and briquetting. The process is composed of three elements: smelting reducing furnace, preliminary reduction fluidized bed, gas reforming furnace. Making mathematical models as a means of study of the process, material balance and heat balance are calculated. Operational unit requirements are estimated, changing them in the range of 20-60% of the post combustion based on three fundamental processes each of which is composed of one or a combination of the three elements. The total cost is also trially calculated, estimating fixed cost including installation cost, etc. With no big differences in the iron-melting cost excluding by-products in each process, the cost may be reduced by 5-10% of that in the blast furnace process. The elementary study has continued almost satisfactorily and attained the expected target, though there still remain some problems. In 1990 the study started of a pilot plant with a 500t/day capacity. 12 figs.

Selective oxidation of lower alkanes by use of heteropolymeric compounds is studied. Alkanes are activated on Cs2.5H0.5PW12O40 serving as catalyst, and their activity and selectivity improve when the catalyst is developed into a dual function catalyst in which Cs and Pt are combined. A success is reported of the synthesis of a heteropolymeric acid in which two molecules of the coordination element wolfram are replaced with a transition metal of the first period, on which acid the oxidation of cyclohexane is enhanced. Cs2.5Ni0.08H1.34PVMo11O40 as a metal/heteropolymeric acid dual function catalyst enables the direct oxidation (9% recovered at 340{degree}C) of isobutane into a methacrylic acid, which is attributed to the harmonious coordination of the oxidizing work of the catalyst and acidity. It is possible to oxidize propane into the acrylic acid, but not ethane into the acetic acid. In the case of Pd/Cs2.5H1.5PVMo11O40, the formic acid, methanol, etc., are produced upon addition of hydrogen to the system. This reaction in the hydrogen/oxygen system is supposed to take place via activated oxygen seeds as in the case of oxidation by hydrogen peroxide. 10 refs.

By research groups having been sent, the integrated evaluation was made of the projects on the research cooperation with Indonesia in the development of environmental measurement use laser radar and the research cooperation with China in the mining waste water treatment technology using biology. As to the research cooperation with Indonesia, the purpose/target proposed were almost achieved, and all were favorably carried out. Especially, after finishing the project, the design/manufacture of an on-vehicle type Mie-scattering laser radar were made using the acquired laser technology. And, it was reported that an observation study of the state of air pollution in Bandung city was made using the laser radar. It can be said that generally the research cooperation with China was smoothly proceeded with. However, the Wushan mine is small in scale of management, and therefore, there might have been some points to be reviewed in selection of the mine for research. The pilot plant installed at the Wushan mine is not now operated. If the mine has strong management force, the effective use of the pilot plant after finishing the project might have been studied.

The shape of osteoblast, gene appearance, gene of rice blast, cellular fusion of plants, gravity acceptance mechanism of unicellular organisms, and physiological and immunity functions of mice were investigated under the microgravity condition. The influence of gravity on the vital reaction and the influence of microgravity on the crystallization of vital substances were also investigated. For the observation of osteoblast, the fluorescence dye reacted with Ca was well taken in the cells. The microgravity affected the stability of rice blast, but hardly affected the protoplast culture of mushroom. The reaction of ciliate against the gravity related to the specific gravity difference between cells and outer liquid. The level of adrenaline in blood of mice increased during the drop. The moving speed of trigger waves of chemical parallel slit formed at the BZ reaction under the microgravity became 60% to 80% of that on the ground. In the case of crystallization at the deposition agent concentration of 1% to 4%, the turbidity showing the degree of crystallization changed complicatedly. Nine processes of crystal growth were recognized. 21 refs., 55 figs., 1 tab.

A study was made on conditions available for white noise belonging to a finite power function with the use of a power spectrum conception. It was defined that a real variable function with a finite waveform energy was a finite energy function while that with a finite waveform power was a finite power function. A noncorrelative white noise was defined as a real variable function in which an autocorrelation function took a specific value at a certain point; however, the autocorrelation function was different between the finite energy function and the finite power function. In other words, the definition of white noise was such that `an energy spectrum was a fixed value` in the finite energy function, and that `a power spectrum was a fixed value` in the finite power function. It was pointed out, by Matsuyama (1994) with the use of the energy spectrum conception, that the white noise belonging to the finite energy function took only the form of `an arbitrary impulse function that all turned to zero except a certain point`.

The paper described a study made during 1995 through 1998 on the application of 3D woven C/C composite materials to machine parts. The materials are large in rigidity, small in specific gravity, excellent in specific rigidity, and suitable for high speed rotation. They are excellent in heat resistance/dynamic reformation and expected as materials which can exceed limits of the existing steel for machine parts. However, to use them as machine parts, a possibility of high precision cutting is required. Therefore, a study was made on metal multi-layer membrane coating to C/C composites. Pitch-system high-elastic carbon fibers were made a 4-directional material by orienting horizontally in 3 directions at 120 degrees per plane and also orienting vertically. Various materials such as W, Mo and WC were coated by the laser assisted plasma hybrid spraying method. High adhesion coats with little pore were obtained. Multi-directionally woven C/C composites used to be poor in surface precision workability, but the problem was able to be solved by coating surfaces with metal layers and metal multi-layer membranes. The application is expanded not only to polygonal mirrors (for laser printing machine) and milling spindles, but largely to machine parts. 11 figs., 1 tab.

Use of granular solidified coal ash as a road base material has been studied to facilitate the large scale utilization of powdered material. The proposed technology of producing granular solidified coal ash includes steam curing combined with different unit operations. Investigations on the technological and quality control aspects make clear the followings: (1) A proper technology for large scale processing may consists of the following steps: kneading of coal ash with water around its plastic limit, low pressure molding, steam curing and crushing. (2) A road base material of good quality can be produced in large qualities from coal ash of fixed CaO content and unburnt carbon content. Further processing includes mixing with the amount of water based on the size and the time change degree of the consuming power in kneader, kneading and molding. The temperature of the kneading water should be adjusted to the ambient conditions. 4 refs., 7 figs., 3 tabs.

To realize clean diesel exhaust, it is very important to clarify the atomization phenomena of the fuel spray. In this study, the initial stage of the atomization process of a diesel injection fuel spray was analyzed with a high-speed image converter camera under the conditions of atmospheric gas pressure and room temperature. As a result, it was found that the initial spray formation was greatly affected lay the condition inside the nozzle sac. In the case in which fuel existed in the sac, pin-like structure spray formation was observed at the initial injection stage. This phenomenon was not observed in the case in which no fuel was present in the sac, and a widely spread fuel spray formation was observed at the initial injection stage. The relatively low-speed fuel spray injected in the initial low-sac-pressure condition was pushed away by the subsequent fuel spray injected in the high-sac-pressure condition. 7 refs., 12 figs., 1 tab.

For effective use of unused seaweeds, efficient search of available microorganism systems and their conversion for effective use were studied. Since generally found Phaeophyceae includes a large amount of polyphenol such as phlorotannin, it is refused by plant-eating animals, inhibits protein from effective absorption, and is inadequate for livestock feed because of tasteless. Bacteria Rhodococcus sp. PG7-2 was isolated which can be effectively increased using phloroglucinol as substrate. Participation of oxygen- adding enzyme was suggested in the initial stage of decomposition which adds molecular oxygen to aromatic rings. In the experiment using combinations of extracted and isolated enzymes and various coenzymes, no significant decomposition was observed. Since phlorotannin of Phaeophyceae is the polymer which shows a matrix-like extent through difficult-to-decompose bond such as biphenyl bond and phenyl ether bond, its decomposition by one kind of bacterium is extremely difficult. Search of decomposition systems of polymer remains as the future issue. 15 refs., 30 figs., 5 tabs.

Research, development, and evaluation were made on seawater purification for the purpose of supplying inexpensive city water stably in the future. In the research of the high flow rate long-tube type multi-stage flash process, basic characteristics were identified by studying fluidity, heat transfer, deaeration, and decarburization by using a test plant with a capacity of 3,000 m{sup 3}/d. A number of findings were derived in carrying out demonstration studies by using a test module with a capacity of 100,000 m{sup 3}/d. Research on heat transfer pipe materials covered a wide area including copper alloys, titanium and aluminum alloys, and ferrous materials, where a prospect was obtained on materials which may be practically usable in the future as transfer pipes in large seawater purifying equipment. Research on a concrete evaporator body proved that it is more economical than steel evaporators, and has sufficient corrosion resistance even against high-temperature brine. Other activities included researches on effects of contaminated seawater, brine diffusion, byproduct utilization, and total systems. Social and economic evaluations were also performed. (NEDO)

Because of a strong 3-dimensional flow, it is difficult to produce a uniform flow or improve efficiency with winnowing fans. Through experiments with various types of impellers, it was found in an earlier study that a forward-inclined impeller could produce a uniform flow and improve efficiency. It was ten reported in a subsequent study aimed at identifying the mechanism behind this, in which the relationship between velocity and static pressure in an impeller of small inclination angle was examined from the perspective of flow, that flow analysis was effective towards estimating inconsistent flow characteristics. Based on these findings, this project was designed to measure and analyze flow characteristics in a forward-inclined impeller. It was found that forward-inclined impellers have many regions of circulating flow and that the mainstream which moves to the outlet is narrow in effective area. As a result, velocity increases and discharge blow rapidly expands within a short distance. Therefore, good static pressure recovery is obtained. (author)

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.

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

This study have dealt with the issues of how the policies of environmental and natural protection should be shaped in a democratic society, and what the optimal legal systems should be for realizing the policies. We have analyzed these issues from the following three points of view ; the first one is the legal philosophical issues of justice and moral values among individuals and organizations. Secondly, we analyzed the optimal deterrence system of organizations for pollution controls, etc. We studied crimes and illegal conducts by organizations and corporations themselves, and their employees under the principal-agency model. Third, we looked at the legal system itself and the foundations of environmental issues from the legal-philosophical aspect. Fourth, we analyzed how the social decision-makings on the environmental protection were produced, using the public choice theory. (author)

Outlined herein are a procedure developed to simulate performance of an energy-autonomous (independent) solar house referred to as HARBEMAN HOUSE (HH) built in 1996 in City of Sendai, comparison between the simulated and observed results, and characteristics of the solar house. The house is equipped with a solar collector and sky radiator, both installed on the roof, the former facing south to collect solar energy and generate hot water whereas the latter facing north to radiate heat and generate cool water. Both are connected to an underground heat-insulated tank having a capacity of 31m{sup 3}, which stores hot or cool water to keep their conditions for extended periods. The solar system operates in heat- or cool-storage mode. In the heat-storage mode, quantity of heat stored increases, although at a slow rate, as tank capacity increases. In the cool-storage mode, on the other hand, quantity of cool stored increases in proportion to tank capacity. This is because solar energy is collected throughout the year whereas cooling by radiation is concentrated in early spring. Loss rate of heat stored increases as tank capacity increases, and the opposite trend is observed with cool stored. 12 refs., 7 figs., 2 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.

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.

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

In order to assure stable supply of oil and natural gas resources, and achieve enhancement in ocean development technologies in general, development has been made on the subsea petroleum production system (SBPPS), which is effective in ocean floor petroleum production from oil fields at great depths (300 m or deeper), and can be applicable to continental shelves and continental slopes around Japan. The SBPPS consists of four sub-systems of shafts, pipelines, manifolds, and riser and oil storage, whose basic development targets were established for the total system. The system was given a conceptual design for the total system, and the above four sub-systems were designed according to the conceptual design. The experimenting devices of each system were fabricated on a trial basis while fundamental studies are being made on component technologies, and experiments were performed to verify basic functions of the sub-systems. Developments were made on such operation technologies as the system operation technology, production control technology, safety control technology, and maintenance and repair technology required to operate the SBPPS. On-shore and general off-shore experiments were carried out to verify the functions of the experimenting devices of each system, the comprehensive functions and the operation technology. Comprehensive evaluation was given on the above achievements from the technical, economic and social viewpoints. (NEDO)

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.

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.

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.

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.

It is important for geothermal energy to develop and utilize it in a rational manner. To achieve the objective, hot water systems must be studied comprehensively and elucidated from the standpoint of the systems as a whole. The present study, standing on this viewpoint, is intended to elucidate hot water systems and establish a survey method thereon. Fiscal 1973 has selected four areas (northern Hachimantai, southern Hachimantai, Onikubi and Kuju areas) as the model study fields, and used as the main field the Onikubi area, which clearly shows the structural catchment basin. Studies were performed in this area on hydraulic hot flow rates, isotopic geology, and reservoirs. In the hydraulic hot flow rate study, the amount of rainfall, amount of flowing water, and amount of hot spring water flow-out were observed continually. In the isotopic geology study, hydrogen in hot spring water and underground water, and composition of oxygen isotope were analyzed. Estimation was made from the result thereof on water balance, heat balance, and underground residence time. In the study of reservoirs, measurements were performed inside the wells, and estimation was made on locations and sizes of the reservoirs by surveying distribution of transformed minerals and cracks.

Three types of weight in both energy saving and optimum room temperature environment were changed to obtain the optimal control solution of the ground thermal storage system in a greenhouse. The relation diagram between the optimal solution of a performance function, and the state constraints and control function constraints was created in consideration of the energy term in a control function value area and the room temperature environment. As a result, the whole image of the performance function could be grasped in consideration of the energy term with inequality constraints and the room temperature environmental term in this study. The rate of a weighting factor in the performance function significantly influences the optimal solution. The influence on the optimal solution also changes when the optimal room temperature schedule differs. The influence that three types of rising algorithm exert on the convergence and converging speed was investigated. Superiority or inferiority occurs according to the space properties of a performance function. A zigzag method is most disadvantageous. The constraints can be converged to the optimal solution using an SUMT outer point method irrespective of the initial value. 6 refs., 6 figs., 4 tabs.

Hydrogen gas as material is produced mostly by steam reforming of hydrocarbons, and includes a considerable amount of impurities such as carbon dioxide, nitrogen and oxygen. The concentration of impurities in the refined gas is approximately 1ppm. In the liquefaction process of hydrogen liquefaction plant, the gases entering the low temperature portion near the free expansion valve (J-T valve) are mostly oxygen and nitrogen. When oxygen is solidified, attached, accumulated near J-T valve, it incurs a possibility of exploding for reason of impact force, etc. by contact with the valve portion. A mixture of hydrogen and oxygen ignites at the minimum value of approximately 0.02 milli-joule, and therefore it has great danger of explosion. As viewed from a point of danger prevention, there is a possibility of explosion when the hydrogen-oxidizing agent mixture is formed. Accordingly, it is necessary to conduct an experiment for confirming the explosion at J-T valve portion. From viewpoints of prevention of explosion accident and running operation, it is necessary to experimentally grasp the definite allowable oxygen concentration. Further, it is necessary to establish a technology to continuously and accurately measure the concentration of trace impurities in hydrogen gas. (NEDO)

This report summarizes results of the phase II R and D program of MHD electrical power generation (FY 1976 - 1983), which has been now completed. The phase II R and D efforts were concentrated on development of the durable power generation channels, where the designs and manufacture of the Mark II system were started, and the elementary techniques were simultaneously studied for, e.g., phenomena occurring around the electrodes, seed condensation and its effects on the electrode phenomena, and electrode and insulator materials for the power generation channels. The power generation channel was tested for its durability for a total of 430 hours, after it was incorporated in the Mark II system. The MHD power generation can incorporate direct combustion of coal, and will hold a dominant position in coal-fired power generation, which is expected to grow in the future. For this reason, the basic research schedules were revised in March, 1983, and the Mark II system was operated by firing a mixed fuel of kerosene and finely divided coal in a kerosene combustor, in line with the revised project, to understand the basic power generation characteristics with the combustion gases containing coal slag.

The research was conducted jointly with Europe of a catalyst which enables clean combustion and NOx removal in polluted gas in combustion flue gas, etc. Reformation of mordenite and {beta}-zeolite was done by ion exchange, ion implantation, and membrane formation. A catalyst was searched for to obtain reducing agents, C5-C8 components, by decomposing light oil. Saponite, clay compound, showed by copper and silver ion exchanges approximately 50% of activity under 20,000h{sup -1}, C3H6 reducing agent, and without steam. The effect of the temperature of sintering on NOx selective reductionality of silver-carrying alumina catalyst was studied, and in sintering at 800degC, activity increased. When using conductive oxides like ruthenium oxide for electrolyte, NO decomposition selectivity increased. As to the functional layer carried above the Pd electrolyte, iron oxide and magnesium oxide increased NO decomposition selectivity. PdO and rare earth oxides forming compounds controlled variation of activity by dissociation/reoxidation of PdO. As to PdO/Gd203, the initial methane combustion activity was favorable, but there was seen deterioration with age. 271 refs., 281 figs., 58 tabs.

Military and social restrictions imposed on Japanese scientific research following the second world war made nuclear or particle physics experiments almost impossible. However, the (Japanese) theoretical achievements of the 1940s considerably buoyed this group, namely two-meson theory, super-many-time theory and covariant renormalization theory. Economic conditions were also difficult with high inflation throughout the 1950s. Printing and distribution problems and paper shortages reduced the circulation of scientific journals, but theoretical work progressed well even in isolation. Within Japan, a circular called Soyrushiron Kenkyu (elementary particle theory research) became a valuable medium for exchange of new ideas and information. A Research Institute for Fundamental Physics, the first of several Japanese research institutes, was opened at Kyoto University in 1953, when a major international conference was held there. The second half of the 1950s was a time of expansion and consolidation for particle physics in Japan. (UK)

Attention is paid to reduction in area required for solar cells by solar concentration as a means of solving cost limits of solar cells and unstable supply of Si materials. Low concentration solar cells are effective from the aspects of utilization of scattered light and unnecessary ray tracing. The optical concentration ratio was calculated of three-dimensional lens having design values of various north/south and east/west direction allowable incidence half angles. The three-dimensional lens are designed by cutting a rectangular parallelepiped by the two-dimensional composite elliptical plane designed by various allowable incidence half angles from two directions of north/south and east/west. Using Perez`s sky solar radiation models and meteorological data HASP, calculated were the annual accumulated global radiation ratio on an inclined surface and the optical efficiency. Calculated were the solar cell area ratio and solar concentration area ratio of the concentration type to obtain solar radiation the same as that of the planar type. From the optimization calculation, it was found that lens are optimal which have design values of north/south and east/west direction allowable incidence half angles of 30-70deg. The solar cell area ratio is 57% and the solar concentration area ratio is 1.2 times. It was found that by making the module area 1.2 times, more than 40% of the solar cells used can be saved. 5 refs., 8 figs.

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.

Experiments were conducted on the plasticity processing of heat resistant ceramics making use of the viscous deformation of amorphous ceramics in the supercooled liquid temperature domain. Concerning the preparation of powder of amorphous ceramics, the plasma rotating electrode method of Institute for Materials Research, Tohoku University, was employed, and a bamboo leaf shaped amorphous flake was successfully fabricated by increasing the arc discharge current. In a search of texture easy to turn amorphous, it was observed that Al{sub 2}O{sub 3}-La{sub 2}O{sub 3} had a supercooled liquid domain of as large as 70K, and this enabled a conclusion that it was a promising candidate for hot molding in a supercooled liquid domain. In an experiment of molding in a supercooled liquid domain, Al{sub 2}O{sub 3}-Gd{sub 2}O{sub 3} was used in a press molding process. As the result, a compact bulk mold was obtained in a temperature domain far lower than in the case of conventional sintering. Crystallization had already advanced in all the molds experimentally fabricated by press molding, and this disabled a study of characteristics to be exhibited by an amorphous mold, but it was found that they had a compressive strength of approximately 1,800MPa.

Discussions were given on features of various kinds of coal liquefaction catalysts exhibited by them in hydrocracking of coal (Taiheiyo coal), and particularly on selectivity of the reaction in its initial stage. Four kinds of catalysts were tested: Adkins catalyst which is an oxide of copper and chromium, Fe2O3+S, Mo-TiO2 and MoS3-Al2O3. Three grams of coal and 0.3 gram each of the catalysts were charged into an autoclave reactor and experiment was conducted under an initial hydrogen pressure of 10 MPa, temperatures from 653 K to 693 K and for durations of 0 to 120 minutes to derive apparent reaction rate constants. The MoS3-Al2O3 catalyst has promoting the reaction apparently in the primary reaction at any temperature, while the other catalysts had the rate constants varied in the initial and the later stages. It was recognized that the temperature dependence of rate constants varies considerably according to the types of catalyst. Particularly the MoO3-TiO3 catalyst has small temperature dependence in the rate constants, and high molecular weight reducing power. 3 refs., 4 figs., 3 tabs.

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.

In order to clarify the relationship between the heat transfer rate and the expansion bed in a group of horizontal pipes in a freeboard region (an area of the heat-transfer pipe exposed above the height of static particle bed from the beginning) in a cold model of the fluidized bed, particle behavior was measured using an optical measuring method. The light axis position was set higher than the heat-transfer as X {sub p} in a direction perpendicular from the distributor, and the static bed height was set to L {sub c}. The frequency of particles and particle lumps coming to presence between the light axes is termed V {prime}{sub p}(time-averaged dimensionless amount of the optical probe output). The V {prime}{sub p} decreases with an increase in the flow velocity, and, when the difference between the probe tip and the static bed height, X {sub p}{minus} L {sub c} is small, it shows the minimum value at a certain flow velocity and then rises again. The root mean square value of the probe output, V {prime}{sub f} increased with an increase in the flow velocity, reached its maximum, then decreased to the minimum, and rose again. The flow velocity that takes the maximum heat transfer rate can be identified from the relationship among the dimensionless amount of the maximum expansion bed height and the average expansion bed height, the dimensionless height of X {sub p} when V {prime}{sub p} and V {prime}{sub f} obtained at each X {sub p} show the extreme values, and the dimensionless height of the heat-transfer pipes when the average transfer rate takes the maximum value. 6 refs., 5 figs.

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.

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.

Demand for reduction in vibration and noise in large-size ferry boats has been severer in recent years. On the other hand, vibration exciting force in main engines and propellers is on an increasing trend in association with increase in speed and horsepower. A large-size ferry boat uses an intermediate-speed diesel engine which has high vibration exciting frequency. Therefore, discussions were given on characteristics of response to nodal vibration in a main hull induced by primary internal moment in a main engine in a large-size ferry boat mounting an intermediate speed main engine. Results of detailed vibration calculations, vibration experiments using an actual ship, and results of measurements were used for the discussions. Natural frequency for two-node vibration above and below the main hull was set for an equation of estimation such that the whole ship is hypothesized to have been structured with beams having the same cross section according to the Todd`s equation, and effect of rigidity of the long structure can be evaluated. Parameters were derived by using the minimum square method that uses the measured natural frequency of the ship A through the ship E among large-size ferry boats. The derived result may be summarized as follows: this equation of estimation has an estimation error of about 5% against the natural frequency for nodal vibration above and below the main hull; and this equation of estimation has an estimation error of about 30% against the acceleration in the vertical direction at the end of the stern. 2 refs., 11 figs., 1 tab.

In order to identify the actual status of geothermal reservoirs, development is made on a technology to detect cracks in a geothermal reservoir. This fiscal year has launched development of a PS sonic logging device of well wall compression type, which is considered most effective in crack detection. This device has a number of new development elements such as a mechanism to have a transmitter and a receiver compressed on a geologic stratum to send sonic energy directly into the stratum, simultaneous use of S-wave having excellent characteristics in evaluating crack faces quantitatively and calculating porosities, and a cooling mechanism for electronics installed in the wells. Combining this with a micro seismogram log scheduled to be fabricated in fiscal 1976 will form the mainstream of crack face detection. A continual flow meter measures behavior of steam and hot water to identify flow-out or flow-in patterns and depths of fluid in wells under flowing condition. Adding this meter to temperature and pressure elements scheduled to be developed in fiscal 1976 will provide data to give an important guideline in underground heat production. This meter was attempted with enhancement in heat and pressure resistant characteristics and stabilization of operation for design and fabrication, which were carried out using the spinner flow meter as the base.

The paper studies effects of various powders as admixtures used for high strength concrete of approximately 800-1400 kg/cm {sup 2} compressive strength with the use of mortar. The following are the results of the study: In order to obtain the required table flow values, high performance AE water reducing agent must be increased with an increase of a mixing rate of silica fume (SF). However, in case of mixing blast furnace slag powder or classified fly ash (SLG or FA), AE water reducing agent can be slightly decreased, with an increase of the mixing rate. In order to obtain the required amount of air, in case of mixing SF or FA, AE agent is needed to be more increased than in case of plain mortar, while AE agent is of the same quality as in the plain one. Besides, both compressive strength rate and drying shrinkage rate show characteristic behaviors according to kinds of admixtures and mixing ratio. 10 figs., 5 tabs.

This paper describes the achievements in the Sunshine Project in fiscal 1992 in studies on improving the efficiency of coal gasification. Three kinds of coals were gasified under the atmosphere of hydrogen, He or CO2 by using the TPR method. The sulfur removing rate varies depending on coals even under the same reaction atmosphere, and so does the degree of influence of the atmospheric gases depending on coals. Very little effect of the atmospheric gases was found on the sulfur removing rate in Taiheiyo and Wandoan coals. While Tatung coal presents the same removing rate under the atmosphere of He and CO2, it shows 1.8 times greater removing rate under the hydrogen atmosphere. Generation patterns for H{sub 2}S and COS also vary depending on coal types and atmospheric gases. Inorganic sulfur shows the same behavior in the reaction process regardless of coal type and atmosphere, but organic sulfur behaves differently. The sulfur removing rate is determined by how easily the organic sulfur can be removed, which attributes to the difference in kinds and structures of organic sulfur compounds in the coal, together with the gas generation patterns. In order to discuss gasification of char, investigations were performed on effects of coal types and heat treatment temperatures, with regard to the gasification characteristics that can be estimated from the industrial and element analyses.

With an objective to utilize hydrogen fuel in aircraft engines, a conceptual design survey was carried out on medium size transport aircraft. Large size long-distance aircraft and SST loaded with a great amount of fuel have the jet fuel (JP) increase take-off weight, affecting largely the selection of wing area and engine thrust. If the hydrogen fuel can be liquefied, large reduction can be achieved and the economic effect can be increased. However, for short-distance transport aircraft, the fuel weight ratio is small, where no large advantage is anticipated even if hydrogen is liquefied. Nevertheless, considering oil depletion in the future, a conceptual design was performed on the YX2688 short-medium distance aircraft being discussed of development. Even the short-medium distance aircraft that can be developed and commercialized as civilian use aircraft has a number of common points with large aircraft development, such as hydrogen fuel using technologies and safety. Although the advantage of using liquefied hydrogen as fuel may of course be smaller in the short-medium distance aircraft than in larger aircraft, the trend of using hydrogen fuel is historical necessity, whose development plans should be moved forward.

The purpose of this study is to acquire fundamental knowledge about the factors for production and the physical properties of boards when wood powder is used as the main material and powder adhesive is used as the binder in the formation of wood boards under heat and pressure. The effects of temperature for pressing, specific gravity of board, and the ratio of adhesive on bending strength, internal binding force, and size and stability against moisture are investigated. The temperature behavior at the central area of boards under heat and pressure shows similar tendency of stagnation near 140degC which increases thereafter irrespective of the temperature of the hot plate in this experiment. The bending property increases linearly when the resin content is low, and shows the tendency of leveling off gradually when the resin content is larger than 20%. Linear relation with specific gravity if obtained in the 0.6 to 1.0 specific gravity range. Wood powder boards have high internal size stability in the thickness direction than ordinary wood boards. 13 refs., 11 figs.

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

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)

Evaluation was conducted concerning R and D on magneto hydrodynamic (MHD) generation, with proposals made for the future R and D. As a result of the experimental operation and studies of the Mark 7 machine for MHD generation, a cold wall type generation channel was found promising in the long-term durability under MHD generation conditions. In addition, R and D was conducted on the exhaust gas control system that fulfilled an environmental standard, seed recovery method, grasp of seed coagulation state, etc. The R and D on element technologies were carried out along with the R and D of the Mark 7 and played a role in the backup of its experiment. MHD generation presents a large number of attractive characteristics, with its development expected in the future. However, it seems too early to immediately move on to the next step. Examinations should be made on such matters as comparisons with various kinds of new power generation systems using coal, trends in foreign countries particularly the U-500 project of the Soviet Union, the ideal system for more efficient development, and possibility of international cooperation.

Full Text Available Background/Aims: The existence of the behavioral variant of frontotemporal dementia (bv-FTD, including senile Asperger’s syndrome (AS, has been proposed. However, there are no empirical case reports to support the proposal. In this report, we present 3 patients who showed symptoms of bv-FTD and demonstrated signs of autistic spectrum disorder, especially AS. Methods: We evaluated 3 subjects using the diagnostic criteria for bv-FTD, and their caregivers retrospectively provided data to calculate the Autism-Spectrum Quotient, Japanese version [Wakabayashi et al.: Shinrigaku Kenkyu 2004;75:78–84]. We also compared these data with those obtained from 3 individuals with Alzheimer’s disease. Results: All 3 patients met the criteria for bv-FTD and had a higher Autism-Spectrum Quotient score than did comparable Alzheimer’s disease subjects. Conclusion: It is possible that some senile persons with frontotemporal lobar degeneration-like maladaptive behavior may suffer from subclinical AS.

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

A number of technological hurdles exist in the process of practically applying the fundamental researches, wherein risks for private business entities to promote the technological development are not at all small. The present surveys are intended to elucidate the actual status as to how a practical application process for technologies is positioned in the series of research and technological development activity floats by private corporations, and what kinds of problems are present, to serve for discussing the way the future supportive environment improvement should be. The 'practical application processes' in private corporations were put into order and analyzed, using as the base the existing study results relative to technological innovation mechanisms. Investigations ere performed on the existing Japanese research and technological development supporting institutions for the practical application processes employed by the private corporations. The result was used for reference of discussing the problems therein. Furthermore, it is indicated that, in the R and D strategies in the U.S.A., profitability is placed as the largest target by means of strengthening the linkage between research and commercialization. This has resulted in decline in the fundamental researches, for which discussions are developed currently. This paper reports investigations on the actual status of business enterprises in the practical application processes. (NEDO)

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

This paper reports the survey results on the manufacturing technology trend of thin substrate solar cells for practical use in fiscal 1994. In production of Si raw material, as electron beam melting and ingot production are combined, C, P, Ca and Al are removed by evaporation, while Fe and Ti by solidifying segregation. As the basic technology of continuous casting for substrate production, a drop coagulation method for Si melt is under investigation which is more advantageous in unidirectional solidification and cell conversion efficiency than conventional methods. The cost and future of single crystal Si and polycrystal Si were compared on the basis of document survey. Every institute commonly uses FZ substrates to produce single crystal Si cells, and SiO2 for surface passivation. New cell structure, hetero-structure, thin cell, crystalline defect and lifetime are under investigation for ultrahigh-efficiency solar cells. The technology trend was also surveyed through academic societies and conferences. 5 tabs.

A high concentration light collection system for solar chemistry was devised by using an inexpensive Fresnel lens in a primary concentration system and a conical type concentrator in a secondary concentration system. A Fresnel lens alone would not achieve sufficiently high light collecting magnification to attain high temperatures because of restrictions in the opening angle as seen from a focus. Therefore, a secondary concentration system was installed on a focus for an attempt of stopping. Reflection plane of a three-dimensional compound parabolic concentrator (CPC) is a rotary parabolic plane, whose process is expensive because of its surface processing accuracy. Therefore, a conical type concentrator was employed as a secondary concentration system. This system may not be capable of achieving as high concentration as in the CPC, but its shape is simple and it is inexpensive. In its optimization, a complete black body surface placed in vacuum atmosphere was hypothesized as a light concentrating part for the secondary concentration system to calculate heat collecting efficiencies at respective temperature settings. Using simultaneously the secondary concentration system, rather than collecting heat by using a Fresnel lens alone, has attained as high value as from 5.99% (500 degC) to 43.47% (1400 degC). Economical high-temperature heat collection of solar chemistry level may be possible by using a Fresnel lens and a conical secondary concentration system. 1 ref., 7 figs., 2 tabs.

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

This paper describes the blasting demolition of steel tower of iron works. The steel tower had four columns, and its dimension was 17 mtimes17 m in cross section and 77.6 m height. The total weight was about 1,724 t. The 18.4 kg V-type linear shaped charge was fixed around columns with box weld structures, and initiated using 16 seismograph electric detonators. Vibration and noise were measured during blasting and collapse of the tower. In the both case, the vibration levels were between 67 and 71 dB, which were low and under 75 dB, the standard level during specific construction works of the regulation act of vibration. The noise level was 120 dB(A) at the point 200 m away from the blasting source, which was over 85 dB(A), the standard level. The collapse process of steel tower was simulated using discontinuous deformation analysis. The results agreed well with those from the actual collapse. The steel tower landed about 6 seconds after the initiation, and it took about 15 seconds to complete the collapse. Before the demolition, the 6 t parts of forefeet of two columns in the collapse direction were cut and removed by blasting. Thus, the collapse was controlled in the given direction. 5 refs., 13 figs., 2 tabs.

Windmilling characteristics of a combination of a torsion arc blade type (TABT) horizontal axis wind turbine and a reverse torsion arc blade type (RTABT) horizontal axis wind turbine were evaluated in a wave activated power generation experiment. The TABT wind turbine had six blades, and the front and rear parts of the blade were twisted in the same direction, which caused the direction of rotor rotation to change as the direction of wind along the shaft changed. The RTABT wind turbine had twelve blades, and the front and rear parts of the blade were twisted reverse to each other, which allowed the direction of rotor rotation to stay constant even in the presence of wind direction reversal. To keep the direction of rotor rotation unchanged in the presence of flow direction reversal along the power generating turbine shaft, a single-stage type RTABT wind turbine and a double-stage type were used, the double-stage type being a series connection of a first-stage RTABT (for blowout and suction) and second-stage TABT (for blowout only). Both single-type and double-type rotated in the same direction irrespective of the direction of air flow. The output of the double type was obtained by adding up the values obtained from the individual turbines. The double type was two to three times higher in efficiency than the single type in turbine revolution and power output. 2 refs., 13 figs.

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.

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)

A cellular wireless device performs signal transmission and receiving using only one assigned frequency because of effective frequency utilization, and therefore, is inconvenient in actual use. For this reason, a cellular wireless device operating on a new principle was developed to make simultaneous two-way calls possible on one frequency. The operation principle is such that one frequency is used, voice signal is divided on the transmission side at every 0.4 second, compressed in time to 1/2, and transmitted in 0.2 second upon modulation; and the receiving side extends the signal to a double length upon demodulation to take out the original voice signal. Thus, the transmission time is reduced to half, and the remaining half time thus obtained is assigned to the receiving time from a caller in the similar method to perform a two-way simultaneous call. Both hands can be used freely during a call, making the safe call possible even while driving a vehicle or performing a work. High confidentiality can be maintained by means of voice processing, compression, and extension. Size of the device was reduced, reliability and clarity were optimized, and a large number of frequency can be switched easily. Field test have proved that the device meets the criteria specified in the Electric Wave Law. The device was begun of business use in 1992. It can be connected with portable type telephone sets and those used in business compounds. 2 figs.

Described herein is development of superhigh-function electronic computers.This project was implemented on a 6-year joint project, beginning in FY 1966, by the government, industrial and academic circles, with the objective to develop standard, large-size computers comparable with those of the world's highest functions by the beginning of the 70's. The computers developed by this project met almost all of the specifications of the world's representative, large-size commercial computers, partly surpassing the world's machine. In particular, integration of the virtual memory, buffer memory and multi-processor functions, which were considered to be the central technical features of the computers of the next generation, into one system was a Japan's unique concept, not seen in other countries. The other developments considered to have great ripple effects are seen in LSI's, and techniques for utilizing and mounting them and for improving their reliability. Development of magnetic discs is another notable result for the peripheral devices. Development of the input/output devices was started to correspond to inputting, outputting and reading Chinese characters, which are characteristics of Japan. The software developed has sufficient functions for common use and is considered to be the world's leading, large-size operating system, although evaluation thereof largely awaits the actual specification results.

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

The geothermal district is characterized by distributions of high temperature and hot water. The beds and rocks in these areas are characteristically altered by these conditions. It is an object of this research and development project to clarify how properties of the beds and rocks in these areas, exposed to the characteristic physicochemical conditions, differ from properties of those in other areas. There are may rock properties. In this project, the studied properties are centered by those used for physical exploitation (or geophysical methods), e.g., electrical properties (electrical exploitation), magnetic properties (magnetic exploitation), and thermal conductivity (measurement of heat flow rates and geothermal gradients). The FY 1974 project covers pigeonholing the basic data, establishment of the experimental procedures, and measurement of water quality characteristics and temperature distributions (geothermal temperature gradients) at the test site. This paper reports the results categorized by (I) measurement of rock resistivity and effects on moisture content on this property, (II) properties of water in the geothermal district (Yahata-daira District), and (III) relationships between rock thermal conductivity and other properties.

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

This paper describes the achievements at the Government Industrial Development Laboratory, Hokkaido in the Sunshine Project in fiscal 1990. Surveys were carried on different catalytic activities for co-liquefaction of various types of coals. The Ru system was found preferable in acquiring fatty family products of low boiling points. Reactions of co-liquefaction constituents do not progress independently, but have positive interaction. Adding Ru is effective in accelerating hydrogenation of condensed aromatic rings and hydrogenation of cleaving nucleus, but in view of the hydrogenating decomposition capability, the Mo-system may be better. In a liquefaction plant test, diesel oil was manufactured by reforming and improving the Yallourn coal light oil. However, the oxygen content was too high, aggravating the temperature distribution control in catalyst bed, and not having achieved the intended denitrification rate. Discussions were given on co-liquefaction of the depressurization residues of Cold Lake (CLVB[vacuum bottom])/Athabasca (ATVB) and Battle River coal. The CLCVB and ATVB were turned into lower molecules easily through hydrogenation treatment. The reaction characteristics reflected the characteristics of medium oil. Depolymerization of coal has progressed faster in ATVB. In the study on the engineering property values, discussions were given on behavior of solid particles in a bubble column, and gas hold-up of slurry. (NEDO)

If materials superior to Ni-based and Co-based super alloys could be developed, great progress is expected in the energy source saving, enhancement of aircraft speed, and simplification of member structure. Metals having high fusing point are prospective as well as C/C composites and ceramics among possible materials. Especially, Nb has a similar density to Ni, and its fusing point is 1,000 centigrade higher than Ni. It has also ductility. Furthermore, it is characterized by the formation of solid solution with other various metals having high fusing point. Accordingly, Nb-based composite alloys having excellent high temperature strength as well as excellent ductility and toughness can be developed by enhancing the solid solution formation and the dispersion with composites of compound phases using Nb as a base material. The purpose of this study is to provide fundamental data for the development of Nb-based composite alloys. The optimum matrix materials and their fabrication processes have been investigated, to evaluate their high temperature properties. Consequently, it was found that the enhancement by the deposition of intermetallic compounds or by the dispersion of oxides was an effective method for the formation of composites of Nb-based alloys. 4 refs., 88 figs., 24 tabs.

A hydrochlorofluorocarbon (HCFC) refrigerant, R-22, is currently being used almost exclusively as a refrigerant for conventional air-conditioning equipments. Since HCFCs are expected to be banned shortly, it is considered a crucial issue to support R and D of the air-conditioning system Lorentz-cycled with hydrofluorocarbon (HFC) refrigerants mixtures. In the present research project, therefore, it is aimed to reveal some of the essential thermodynamic properties of HFC refrigerant mixtures systematically. On the basis of a series of achievements for the last several years by the present research coordinator and his group regarding thermodynamic properties of single-component and blended HFC refrigerants, we have conducted following three major research programs rather systematically on which no challenges have ever been reported worldwide. Throughout a series of experimental as well as analytical researches performed so as to meet the objectives mentioned above, some novel knowledge and valuable outcomes could be obtained in the present study. (1) Precise measurements of vapor-liquid equilibrium properties with simultaneous determination of densities, latent heats of vaporization, and isobaric specific heat capacities in liquid phase. (2) Analytical studies to establish thermodynamic property modeling. (3) Feasibility study of evaluating the Lorentz-cycled performance. (NEDO)

The present investigative studies are intended to propose measures of arranging conditions required to commercialize new energy technologies and introduce them into societies. The investigative studies will begin in the current fiscal to put into a complex the new energy industrial plants and the existing different industrial plants. There is a viewpoint that, when structuring specifically a business entity on coal liquefaction processes, some kind of complex is required as seen from the scale and economic performance of the business. Based on this viewpoint, the current fiscal year has carried out the studies placing the importance on technological feasibility for forming a complex with petroleum refining, iron and steel making, chemical and electric power generation industries. The model coal liquefaction plant uses the NEDOL method as the process, and establishes specifications for commercial size plants. The complex formation was discussed with the commercial scale of a coal liquefaction plant assumed to be 30,000 tons per day as the coal treatment quantity and 100,000 barrels per day as the product quantity converted into refined coal liquefied oil. As a result, a conclusion was drawn that, when the complex formation has been done successfully, an attractive business pattern may be formed although some problems may exist. (NEDO)

This paper describes development of hydrogen gas turbines from among the comprehensive discussions on hydrogen utilizing subsystems. Hydrogen and oxygen gas turbine cycle has varying optimal conditions of plant efficiency depending on fuel patterns. The regenerative cycle may have the turbine inlet temperature at about 1,000 degrees C. The inlet pressure would be ten and odds atmospheric pressure. It is better to keep the inlet temperature higher in order to obtain high specific power. Reduction of power generation cost in using this plant requires that construction cost be decreased, and the specific power be increased if the plant efficiency (in other words, running cost) is assumed constant. Further development is required on technologies to use higher temperatures and pressures. For that purpose, discussions should be given on material development, structural design, and inspection. Hydrogen gas turbines, which present low pollution depending on combustion methods, have great significance for such social problem as environmental contamination. In terms of economy, since hydrogen gas turbines depend on efficiency and fuel unit cost, the evaluation thereon may vary depending on how well the regenerative gas turbines have been established, in addition to future change in hydrogen price and the technologies to use higher temperatures and pressures.

This paper introduces two out of six theses related to hydrogen fueled aircraft engines presented at the First World Hydrogen Energy Conference held in Miami in March 1976. One thesis mentions several initial prospects related to terrestrial requirements on hydrogen fueled transport aircraft. Liquefied hydrogen is attractive for large long-distance transport aircraft. Its high energy content can reduce the take-off full load weight by more than 30%, enhancing the economic effect of the aircraft. Saving fossil fuels will require national policy decisions in the near future, where introduction of liquefied hydrogen is more advantageous for long-distance aircraft. However, its introduction into wide-body transport aircraft being the major consumer requires transportation companies and airport authorities to carry out joint development with transport aircraft makers and liquefied hydrogen suppliers. The second thesis describes special natures of fuel subsystems for liquefied hydrogen fueled aircraft. Requirements to major fuel system elements and operation characteristics require evaluation as a comprehensive system, rather than as individual component criteria. In addition, hardware, experience and fuel systems as they are now in space development may not necessarily serve for the purpose. (NEDO)

This paper discusses hydrogen fueled automotive engines. Because hydrogen has a very wide ignition mixture ratio limit for spark ignition engines, very lean combustion is possible without a need of throttling, and thermal efficiency in partial load is high. Thermal efficiency while a car is being driven is reportedly higher by 30% to 50%. Values for CO and CH in exhaust gas are negligible, while NOx is at about the same degree as in gasoline engines, which can be made extremely low during lean burn operation. The spontaneous ignition temperature is higher by about 200 degrees C than that of light oil, which presents difficulty in use for diesel engines. Because of small ignition energy and high combustion velocity, excessively early ignition and reverse ignition can occur easily. Hydrogen would be promising if new manufacturing systems are developed and production cost is reduced, and on the other hand, if petroleum price rises sharply. Hydrogen is also expected as a measure to prevent pollution, including that from soot, odor and CO2. The largest difficulty is in the transportation method, and the only possible method at the present is transportation in liquefied hydrogen form. However, practical application will have such problems as tanks, feeding devices, and cost. Development is desired on light-weight metallic hydrides. Technologies for safety and engine performance must also be developed. (NEDO)

This research and development project is aimed at treatment of sewage, industrial waste water and the like at lower cost for reutilization, while efficiently producing methane or the like by the systems annexed to the water treatment systems with high-concentration bio-reactor systems incorporating separation membranes. The waste water types studied to be treated by these systems include sewage discharged in large quantities and waste water containing oil/fat and protein (low-concentration waste water), and starch-, alcohol and paper/pulp-containing waste water, and excrements (medium-concentration waste water). The project has found the optimum systems, by adequately configuring the separation membrane modules, and combining dissolution of suspended solid with methane fermentation reactors for selective treatment of organic substances; improved efficiencies of removing organic substances and producing methane by fermentation, and realized reduction in quantities of discharged sludge; and thereby established the bases for the new waste water treatment techniques. The reactor systems developed for water treatment are those based on biological removal of nitrogen. They greatly reduce treatment time to produce treated water of high quality. For treatment of sludge, the techniques have been developed to convert sludge into oil. These results are well applicable to various areas, e.g., sewage treatment, and food and pulp industries.

Development of the semiconductor photocatalyst such as titanium dioxide is important for photo-energy conversion and purification of the environment. We make clear that the mechanism of the photocatalysis using a spectroscopic or physico-chemical methods, and we developed the new photocatalyst with the control of the surface area, porosity, infinitesimal content, and surface modification of the catalyst surface. Titanium dioxide thin film photocatalysts were prepared by the dip coating method. Surface structure of the thin film was formed by the aggregated TiO{sub 2} anatase particle, its size was around 5 nm. This thin films effectively oxidazed NO, its photocatalytic activity is higher than that of commercial photocatalyst. Metal oxide anchored TiO{sub 2} photocatalysts (RuO{sub 2}/TiO{sub 2}) were prepared by the co-precipitation method. Effective charge separation of the RuO{sub 2}/TiO{sub 2} were confirmed by the measurement of ESR. The RuO{sub 2}/TiO{sub 2} photocatalyst successfully reduced CO{sub 2} and preserved its activity for much longer period than metal loaded catalyst. Hybrid photofunctionalized material was prepared by anchoring porphyrin moieties on the titanium dioxide surface. The relative quantum yield of electron transfer from porphyrin to the titanium dioxide conduction band has been markedly increased by water treatment of quanternized porphyrin-titanium dioxide covalently linked systems owing to removal of adsorbed porphyrin domains.

A desiccant cooling system uses concentrated aqueous solution of an absorbent to reduce humidity, hence the resultant absorbent solution becomes dilute. Regeneration of the dilute solution uses solar heat, where the regeneration characteristics are affected by solution temperature, vapor pressure, water content, air-liquid flow rate, and other factors. Therefore, mutual relationship among these different factors were investigated, and an optimum operating condition was discussed. The regeneration characteristics of the absorbent is strongly affected by temperature of triethylene glycol (TEG). This is because vapor pressure, Ps, in the TEG aqueous solution increases as the TEG temperature rises. This means that preheating the solution is effective in regenerating the absorbent. As the regeneration progresses, the water content, Ww, decreases, and the regeneration rate decreases. This is because of reduction in the Ps in association with decrease in the Ww of the TEG. This suggests that it is important in the absorbent regeneration to reduce flow rate of the TEG aqueous solution as low as possible. Raised air temperature reduces difference in vapor partial pressure between the TEG and the air, resulting in reduced regeneration rate. 5 refs., 9 figs.

In the consumption ground, the fish of the high freshness would have been required, since the distribution circumstance was improved. However, the freshness which is an important element of the fish valence decision though some numerical indexes are used, there is a problem of needing the considerable time for the analysis. In the field, intuition and experience have judged it, and the numerical evidence is being obtained. Here, on 3 fish species of Kochi Prefecture-made, in making the aging variation of ATP to be a chemical index of the freshness, the technique, which simply estimated the freshness from breaking strength change of the fish meat, was examined. As the result, it was indicated that the freshness by 12 hours after the death could be estimated from the mechanical quantity of the muscle on the 2 fish species of red sea bream and Japanese horse mackerel.

Hydrogen absorption by a hydrogen storage (MH storage) is investigated for static characteristics, with a constant current applied to the hydrogen generator, and dynamic characteristics, with a fluctuating current applied to the same simulating actual insolation. In the experiment, alloy temperature (MH temperature) in the storage and a current for the generator are preset, and then automatic measurement is allowed to proceed at 10-second intervals of the differential pressure, hydrogen temperature in the piping, absolute pressure, MH temperature, room temperature, and water tank temperature. It is found as the result of the experiment that absorption performance is improved when the MH storage is cooled; that the mean absorption rate which is 1 without cooling increases to 1.62 at 7degC; that the mean absorption rate changes in proportion to the applied current (introduced hydrogen flow rate); that the rate which is 1 at 32A decreases to 0.53 that at 16A; that the absorption rate is dependent more on the current applied to the storage than the temperature of the heat exchanging medium; and that, even in the presence of fluctuation halfway in the applied current, the total absorption will be equal to a case of constant current application if the total amount of applied current is equal. 2 refs., 7 figs., 5 tabs.

With relation to some global energy systems of which viability is predicted in the future, an evaluation was conducted from the viewpoints of economical efficiency, energy balance, CO2 emission, etc. The fossil fuel CO2 capture system, the conventional thermal power plant added with CO2 recovery/treatment facilities, is expected to reduce approximately 70-75% of the CO2 emission. The fossil fuel decarbonated hydrogen system, which decarbonates fossil fuels, recovers/treats CO2 at the place of fuel supply and uses as hydrogen, is of poor practical application from an economical point of view. The fossil fuel methanol synthesis system, which synthesizes methanol from fossil fuels at the place of fuel supply, generates electric power and recovers/treats CO2 with the methanol, is large in energy loss and CO2 emission and low in overall efficiency and CO2 reduction effect at the time of methanol synthesis. The renewable energy hydrogen system is an ultimate system with no emission of CO2, though it costs much. 110 refs., 83 figs., 107 tabs.

At present, measurement of wet density and water content by radio isotope (RI method) is used for filling management. It is supposed for filling in road construction that putting-out thickness of banking material reaches nearly 1m in the future rapid construction, however, use of RI method is difficult because of inserting and installing of a radiation source rod, large measuring apparatus, and the legal regulation on radioactivity intensity. Application of resistivity measurement was thus considered. Since resistivity has the same parameter as compaction curve, and monotonously decreases with an increase in water content by volume, it is applicable as construction management index. The management reference of resistivity (Rm) is set by plotting of a compaction curve and corresponding resistivity curve, determination of the reference resistivity (Ro) corresponding to a maximum dry density and optimum water content ratio, and setting of the allowance to Ro according to soil or application. It was clarified that Rm is applicable as set for every filling material. 1 ref., 10 figs., 2 tabs.

To establish the inhomogeneous solid combustion control technology, effects of the strong magnetic field on the solid combustion were examined. When applying the sufficiently strong magnetic field, it is possible to control the air flow in combustion field by utilizing the force applying to constituent oxygen with large susceptibility. Based on this possibility, combustion experiments of expanded polystyrene plates were conducted between the magnetic poles of electro-magnet having the maximum flux density of 1 T and the maximum magnetic field gradient of 0.5 T/cm. To observe the effects of magnetic field without the effects of natural convection, combustion experiments of acrylic sheets were conducted between the magnetic poles of electro-magnet having the maximum flux density of 0.6 T and the magnetic field gradient of about 0.1 T/cm under the microgravity conditions between 10{sup -4} and 10{sup -5}g using a microgravity test facility. Consequently, prospective combustion results could be obtained, in which the force of flame received from the magnetic field is almost equivalent to the buoyancy of flame. It was demonstrated that combustion can be controlled by the magnetic field. 1 ref., 3 figs., 1 tab.

Process solvent was hydrogenated in the brown coal liquefaction, to investigate the influence of it on the prethermal treatment and liquefaction. Consequently, it was found that the n-hexane soluble (HS) yield was improved. In this study, capacity of hydrogen transfer from solvent during prethermal treatment and effects of catalyst were investigated. Since prethermal treatment in oil was effective for improving the oil yield in the presence of hydrogen/catalyst or high hydrogen-donor solvent, influence of hydrogen-donor performance of solvent or addition of catalyst on the hydrogenation behavior of coal and the characteristics of products during prethermal treatment were investigated in relation to successive liquefaction results. As a result, it was found that the increase of HS yield was due to the acceleration of conversion of THF-insoluble using high hydrogen-donor solvent and/or by adding catalyst. It was also found that the use of high hydrogen-donor solvent and highly active catalyst at the stage of prethermal treatment before the successive liquefaction was effective for improving the HS yield, i.e., liquefied oil yield. 2 refs., 5 figs., 1 tab.

With an objective of developing a room heating system utilizing a solar chemical heat pump, an experimental system was fabricated to evaluate its performance. Steam was employed as a working gas, and for a reaction material, calcium-chloride was used, which has a reaction temperature zone permitting safe use and fitting the purpose among other hydrate systems and has high standard enthalpy in hydration. Water was used as a solar heat transferring medium. The system operates under the following principle: a container I is filled with hydrated salt and a container II with water, the two containers being linked with a pipe interposed with a valve; heat is inputted and outputted by performing charging and discharging alternately; and the role of a heat pump is played by deriving from environment the heat of water evaporation in the container II during discharging. The COP must take into account the electric power consumption of the water circulation pump to transfer solar heat. A COP of 0.256 was derived as a result of the experiment. 3 refs., 5 figs.

The investigation is made to provide the data which widely cover various characteristics of aged persons for the general designers who design equipment and environments for aged persons. It is found, by the tests for measuring sight and hearing sensations of the aged, that they generally need higher sound to hear; frequency of alarming sound is preferably lowered from 3,000 to 4,000Hz now used for the equipment to 1,000 to 2,000Hz, and the level at which sound can be heard is significantly different from that at which the announcement can be understood. For evacuation order or the like, for example, it is necessary to announce the disaster site and evacuation routes, which the aged hear for the first time, especially slowly and distinctively. The database of body functions of the aged are improved by correcting the problems associated with depth of strata and poor prospects, frequently pointed out by those who look up the data from the daily actions, in such a way that the system can be easily looked at from notices for each function position of the product and also from the related human characteristics.

Experiments were conducted under microgravity for findings on the creation of microspheric photonic materials which are high in sphericity. The experiments were carried out at the fall type microgravity facility of Japan Microgravity Center (JAMIC). In the experiments on the ground surface and under microgravity, glass specimens of 3BaO-97B{sub 2}O{sub 3} mol%, 4BaO-96B{sub 2}O{sub 3} mol%, and 2SrO-98B{sub 2}O{sub 3} mol% were tested. They were heated, melted, and cooled for the on-site observation of phase splitting in them. It was found as the result that, in the case of specimen 3BaO-97B{sub 2}O{sub 3}, the phase splitting start under microgravity was similar to that on the ground surface while the nucleation velocity was lower under microgravity. Specimen 2SrO-98B{sub 2}O{sub 3} mol% exhibited an approximately 0.5-second delay in its phase splitting start under microgravity as compared with its ground surface behavior. As for the nucleation velocity under microgravity, the value was same as that on the ground surface in the first half but, in the second half, it was lower than that on the ground surface. The said approximately 0.5-second delay in the phase splitting start was, when the cooling rate was taken into consideration, attributed to an approximately 6.5 degrees C fall in the phase splitting start temperature, and this suggested that phase splitting was suppressed under microgravity.

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)

The flow field around a Darrieus wind turbine is studied by flow visualization and PIV measurement in a rotating frame of reference to understand the unsteady nature of dynamic stall appearing at low tip-speed ratios. The qualitative nature of the dynamic stall observed by the flow visualization using dye injection technique is quantitatively reproduced in the instantaneous velocity distributions around the blade measured by PIV technique. These results indicate that two pairs of stall vortices are generated in one cycle of the turbine rotation and they grow in size as the tip-speed ratio decreases. The mechanism of the dynamic stall is found to be due to the flow separation over the suction side of the blade followed by the generation of in-flow motion from the pressure side to the suction side of the blade through the trailing edge.

This paper describes fundamental surveys and discussions on technological development in small businesses centering around venture business entities. These business entities have built their competitive superiority by making mainly studies on practical application placing importance on marketability, whereas technological lead-time must be shortened. Making the systems to achieve this goal is demanded. Competitions often take place in markets for small quantity production with large model variety or small model variety, where one is importantly required to establish his specialty expertise. Also desired is the network type business management aimed at developing horizontal business spread while exhibiting the corporate identity. Academic and governmental organizations are demanded of establishing institutions that can provide necessary support when it is required, against shortage of business resources such as fund and human resources. Since the circumstances accompany uncertainty that the success experience and know-hows attained in the past may not necessarily be viable any longer, business management judgements should be made upon collecting effectively the useful items of information including technological seeds. On the microscopic base, markets still have the wide plains at the foot for future growth and development. What is required is effort in business management to improve supply preparedness and strengthen the competitive edge to match the demand growth. Support in the fund aspect is also indispensable to enter into new areas. (NEDO)

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

Concerning the conversion of serpentine, not only its magnesium component but also silica component, into industrial materials, conditions suitable for the production of porous materials and amorphous silica by acid treatment were evaluated, and the properties of the products were evaluated. The silica resulting from the acid treatment of serpentine comes out in different forms, each reflecting the structure of the parent rock, that is, an amorphous mass of planar particles from antigorite and a fascicular mass of filaments from chrysotile. A microporic structure resulted when a small quantity of magnesium was allowed to remain in the skeleton structure and acid treatment conditions were properly adjusted. Several siliceous compounds were prepared for the purpose of finding use for silica from this rock, and then it was found that high-efficiency production of high-crystallinity compounds was possible and that they were furnished with properties fit for use as materials. Furthermore, study was made about the kaolinite reaction in which serpentine would be directly converted into useful materials. 105 refs., 55 figs., 6 tabs.

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

Study of metamorphic belts and tectonics is introduced. Minerals supposedly originating in the transitional zone and the lower mantle, that is, inclusions in diamond in kimberlite, are deemed to carry information about the depth level of 670km and lower. The place of origin of peridotite, Alpe Arami of Switzerland, is again estimated at a level of 300km or deeper. In the tectonic cross section in this region, the oceanic crust is bent and folded, and such a structure enables the supposition that fragments off the transitional zone may be carried upward to the ground surface. This region is now being limelighted, with plume tectonics enjoying popularity. The split of Pangaea is related with the ascent of plume. In the eastern part of Australia, there are alkali rocks attributable to the plume that was supposedly active at the end of the Proterozoic. Zircon U-Pb dating by SHRIMP offers a new approach to the tectonics of metamorphic rocks, and is reinforcing the position of metamorphic petrology relative to the study of collision and split of continents. 64 refs., 10 figs.

The thermal and air distribution characteristics of the air circulation wall in a heat-insulated system were grasped using an experimental model. In this paper, the difference in the heat exchange between the wall and air was confirmed based on the radiation on the circulation layer`s surface. In this system, thin air circulation layers with ventilating holes at the top and bottom are attached to the south and north outer walls of a wooden building. This system is a kind of passive solar house that achieves the insolation screening effect and the temperature rising effect based on solar collection. The heat flow in a circulation layer is eliminated by the natural convection heat transfer on the outer wall. The heat flow passing through insulating materials is the heat transfer by radiation. The heat flow based on the in-layer natural convection is increasingly eliminated by the decrease in temperature on the air circulation layer`s surface. The decrease in room surface temperature using aluminum foil and the reflective heat-insulated effect showed that the heat passing through the wall surface decreases as the convection heat transfer in an air circulation layer increases. 6 refs., 20 figs., 3 tabs.

Informatization using mainly computers is more and more important contributing to the upgrading in society, economy and a variety of fields. As to informatization in developing countries, however, there has still been few to be seen. Accordingly, gaps are getting larger between developing countries and developed countries where informatization is acceleratedly advanced. In the light of such actual state, Center of the International Cooperation for Computerization (CICC) contracted with NEDO and promoted a project `Manufacturing technology supported by advanced and integrated information system through international cooperation.` This is a project to study jointly with five Asian countries with which NEDO made a basic contract, China, Indonesia, Malaysia, Singapore and Thailand.

The R and D of chromium alloys had been conducted till about the 1970s, which brought the unfavorable results. That's why chromium alloys are brittle at normal temperature and difficult in processing. However, the technology development in recent years review them. The development is earnestly desired also of the materials exceeding the Ni base super alloys which are heat resistant materials for power generation. Cr is rich as resource and light-weighted, and the oxidation film is stable and self-restorational at high temperature. The alloys are excellent in processability at normal temperature and excellent also in toughness. The nitrogen content is strongly concerned with brittleness and intergranular fracture at normal temperature. Therefore, Cr alloys were trially manufactured by the HIP sintering/hot forging method using electrolytic Cr powder with high-purity (99.99%) and low-nitrogen (10ppm) to study a possibility of improving brittleness at normal temperature, mechanical properties at high temperature, oxidation resistance, high-temperature corrosion resistance, etc. A variety of excellent characteristics of Cr alloys were made clear. However, also made clear were the problems: strength is low at normal temperature/high temperature; screw process is impossible because of high notch sensibility; those are not almighty high-temperature corrosion resistant materials. Further efforts should be exerted for the commercialization. (NEDO)

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

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.

The paper studies the measures for reduction of environmental load of CO2 from the standpoint of chemical technology. As for methanol synthesis from CO2, accelerating of the reaction using Cu base compound catalyst is reported. Also, CO2 is methanated at high speed by low temperature waste heat using Ni-La2O3-Ru catalyst. Discussions are given on the subject for development of catalyst reaction relating to hydrogen production technology by methane reforming reaction using steam or CO2. Synthesis of polymetric materials by use of CO2 is also described. The paper mentions that it is indispensable to design high-function electrode and elucidate the reaction mechanism of electrochemical CO2 reduction for electrochemical and photochemical CO2 reduction measures. Moreover, in case of using solar energy, it is required to study photovoltaic excitation process in semiconductor electrode/ electrolyte solution interface. For production of hydrogen from CO2 by photosynthetic organisms and solar energy, the problem is control of inhibiting effect of oxygen combinedly produced. Described are production of polyhydroxy butyric acid and biodegradable polymer from CO2 and hydrogen by bacteria, and CO2 fixation imitating the enzyme reaction. 267 refs., 79 figs., 32 tabs.

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

This paper reports the research of coal liquefying technologies in the Sunshine Project in fiscal 1988. The research was performed with importance placed on the fundamentals of coal liquefaction and high value added compounds. Production of n-paraffin in the liquefying reaction occurs from reduction of acidic ester, and this ester structure contributes to cross-linking of aromatic rings. Most of the aromatic rings in coal has long side chains. A hypothesis was assumed that these chains have been produced from reaction of lignin in plants with fatty acid or alcohol. The hypothesis was verified from a synthesizing reaction by model substances. This could be said an initial reaction model for coalification. In order to verify de-alkylating reaction of the liquefied oil, model substances were used to investigate the products. Benzene having long alkyl side chains have the alkyl group dissociated, and on the other hand cyclization progressed producing naphthalene. Melting performance during coking is attributed to a great amount of solvent soluble low molecular constituents contained in coal. These constituents are contained in close contact in a net-like structure, which is loosened only by heating extraction, and extracted. They have no hydrogen donating performance. (NEDO)

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

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

This study reports the stability of annular leakage-flow-induced vibrations. The pressure distribution of fluid between a fixed outer cylinder and a vibrating inner cylinder was obtained in the case of a translationally and rotationally coupled motion of the inner cylinder. The unsteady fluid force acting on the inner cylinder in the case of translational and rotational single-degree-of-freedom vibrations was then expressed in terms proportional to the acceleration, velocity, and displacement. Then the critical flow rate (at which stability was lost) was determined for an annular leakage-flow-induced vibration. Finally, the stability was investigated theoretically. It is known that instability will occur in the case of a divergent passage, but the critical flow rate depends on the passage increment in a limited range: the eccentricity of the passage and the pressure loss factor at the inlet of the passage lower the stability.

An apparatus is developed to establish a system which allows utilization of hydrogen safely and easily, and its applicability to a hydrogen system for domestic purposes is tested. The system converts solar energy by the photovoltaic cell unit into power, which is used to generate hydrogen by electrolysis of water at the hydrogen generator, stores hydrogen in a metal hydride , and sends stored hydrogen to the burner and fuel cell units. It is found that a hydrogen occluding alloy of LaNi4.8Al0.2 stores hydrogen to approximately 80% when cooled to 20 to 25degC, and releases it to 10% when heated to 40degC. The fuel cell uses a solid polymer as the electrolyte. The hydrogen gas burner is a catalytic combustion burner with a Pt catalyst carried by expanded Ni-Al alloy. The optimum distance between the burner and object to be heated is 22mm. High safety and fabrication simplicity are confirmed for use for domestic purposes. The system characteristics will be further investigated. 4 refs., 8 figs.

Dynamic force on blades in a large wind mill changes with rotational speed for various reasons, such as wind shear that causes vertical distribution of wind velocity or titling angle. Therefore, a 2-blade system on a teetered hub is a practical selection for the coned, down-wind type. Use of teetered axis greatly reduces bending moment in the flap direction and that at the axis of rotation. An attempt was made to understand dynamic loads by inertial force resulting from oscillation of the blade rotating on the teetered axis, and thereby to avoid them. The in-plane load can be diminished to zero when the teetered axis is coincided with the center of gravity, but generally cannot be avoided when the blade is strained significantly, except it is operated at the rated condition. The in-plane load and bending moment can be avoided, when rotational freedom is given around the y axis. Dynamic load on a down-wind rotor can be avoided by use of universal joint. 3 refs., 6 figs.

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.

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

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

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

To establish the efficient technique for membranes with pores of required uniform size according to needs of various industries, survey and study were made on process optimization and low-cost production method. Porous membrane is the leading candidate for new separation systems as separation medium in chemical industry, hot gas filtration for energy production and environmental purification engineering. The electrode, separator and gas storage medium of fuel cell vehicles and next-generation batteries require effective porous materials. The workshop on engineering porous materials held in May 1993 confirmed the time of following materials: High-efficiency gas separation membrane, chemical catalytic membrane, fuel cell electrode and absorbent for environmental purification. Development of inorganic membranes more excellent in high-temperature stability, strength, catalytic activity and corrosion resistance than previous polymer membranes is important. (NEDO)

Shortcomings of solar energy are that it is subject to weather and is not available in the nighttime. The weak points may be effectively made up for when solar energy collected on a fine day is stored in the form of hydrogen energy for recovery as required. In this report, power generated by solar cells is used for the electrolysis of water for the generation of hydrogen. The amounts of the thus-generated hydrogen and hydrogen energy are determined and, on the basis of the measured amount of insolation, the solar energy availability rate (hydrogen conversion performance) is calculated. The amount of hydrogen generated in fiscal 1996 is also calculated for every month. The hydrogen generation level is quite low in the TiO2 wet type solar cell, approximately 0.2% at most. The current efficiency is fairly high in hydrogen generation using electrolysis, which is approximately 96-97%. The efficiency is higher when several units of electrolyte are connected in series until the solar cell optimum voltage is attained. A linear relationship is found between the daily summation of insolation and the amount of hydrogen generated. 1 ref., 7 figs., 2 tabs.

Information systems, mainly aided by computers, are becoming increasingly important, contributing to development of wide areas of societies and economics, to begin with. However, few developing countries have established sufficient information systems, in spite of their strong desires to do so, which will further widen the gap between them and advanced countries, where these systems are acceleratedly advancing. Given these situations, Center of International Cooperation for Computerization (CICC) has been implementing various projects for providing assistance to and cooperation with oversea countries which are trying to develop information systems. This report summarizes the project, which CICC has been commissioned by NEDO as part of the cooperation programs, for manufacturing technology supported by advanced and integrated information system through international cooperation. It outlines the research cooperation memoranda NEDO has concluded with Indonesia, Malaysia, Singapore and Thailand, and the authorities of China, Indonesia, Malaysia, Singapore and Thailand. (NEDO)

For the purpose of structuring a database system of technical information about the earth environmental issues, the `database system for R and D of the earth environmental industrial technology` was operationally evaluated, and study was made to open it and structure a prototype of database. In the present state as pointed out in the operational evaluation, the utilization frequency is not heightened due to lack of UNIX experience, absence of system managers and shortage of utilizable articles listed, so that the renewal of database does not ideally progress. Therefore, study was then made to introduce tools utilizable by the initiators and open the information access terminal to the researchers at headquarters utilizing the internet. In order for the earth environment-related researchers to easily obtain the information, a database was prototypically structured to support the research exchange. Tasks were made clear to be taken for selecting the fields of research and compiling common thesauri in Japanese, Western and other languages. 28 figs., 16 tabs.

In order to realize more effective utilization of non-ferrous metal resources, joint research cooperation is made with the Republic of Kazakhstan. It is intended that valuable metals (gold, silver, copper, rare metals, and others) contained at large quantity in ore scraps generated in association with mine operation be extracted and recovered efficiently paying considerations to the environment. The treatment process consists of the following conception: raw materials such as ore scraps are leached by sulfuric acid and microorganisms to separate and recover gold and silver; the leach liquor containing valuable metals is extracted by using solvent and recovered of copper and rare metals via an electrolytic process; and the waste water is treated and discharged. Fiscal 1998 has performed studies on the wet treatment system at the site and in Japan, the gold and silver treatment, and the waste water treatment by using samples collected from the site in fiscal 1996. Based on the results of these fundamental studies, a pilot plant was built, and all of the facility fabrication was completed in fiscal 1998. Part of the facilities has been transported to the site. To drive the project forward effectively, materials and items of equipment required for the joint research were procured and transported to the country, and at the same time Kazakhstanian researchers were received in Japan for training.

The rock anchor method is planned to apply to some permanent structures but since this method was developed for temporary structures, the clarification of the transferring mechanism of force from an anchor to a rockmass, the fracture mechanism and the development of the dynamic model have not been established. This paper arranged the data obtained by a full-scale, in-situ pulling out test of a rock anchor as the first step to understand the dynamic behavior and analyzed by paying attetion to the modulus of deformation of the rockmass where the anchor was embedded to elucidate the affecting degree of rockmass modulus of deformation, the embedded length and the tendon diameter on the dynamic behavior of the anchor. The rock anchor behavior could be expressed accurately by applying a theoretical solution derived by the balancing condition of forces at the boundary face. Especially, when the rockmass is uniform and the fracture occurrs at the interface between the tendon and grout, this approach can express the fracture with the accuracy similar to that made by the finite element method. 6 refs., 11 figs.,1 tab.

Ab initio MO calculations of 1-phenyl-1H-tetrazoles were carried out, in order to explain a substituent effects on its high thermal stability and to estimate the thermal stability of the other tetrazoles. Similar to 1H-tetrazole, five bonds in the tetrazole ring have intermediate lengths between single and double bond lengths. Phenyl and tetrazole rings are not both on one plane showing no interaction. Three indexes addopted as a measure of thermal stability indicate that the more equal the bond lengths of the ring are and that the bigger the stabilization energy by ring formation is, the more thermally stable they are. It is found out that there is the relationship between the thermal stability and the ring charge. That is, the more negative the ring charge is, the more thrmally stable the tetrazole is. Also, there is a good relationship between the thermal stability and the energy level of orbital of which orbital is an anti bonding type with respect to the N3-N4 bond. The higher the energy level is, the more thermally stable the tetrazole is. (author)

A discussion was given to make clear the selection factors in selecting bridge types (steel cable stayed bridge and prestressed concrete cable stayed bridge). The discussion is intended to consider the future development of both bridges. Quoting a cable stayed bridge with a span length of 250 m that can be selected from either bridge, an evaluation was made by using calculations that uses the disaggregate behavioral model theory based on questionnaire responses from engineers. The analysis uses the following procedure: utility function values of the two term behavioral model (having two choices) are specified and the characteristics variables are selected; the data are prepared according to the specifications, which are used to estimate parameters by a maximum likelihood estimation method; and estimation amount is estimated by using the covariance matrix, which is given a `t` value verification. The conclusions: what gives the large effect to the selection is the engineering capacity and sociality; the result contains vocational consciousness; the economy is measured by the large weight of construction cost for the upper part structures and cost required for large repairs; materials affect largely the reliability, and so does the technological level the constructibility; the comprehensive technical capability, freedom in design and the experience attained by Japan have great effects in terms of technological capability. 10 refs., 10 figs., 11 tabs.

Search and assessment were carried out on innovative and leading technologies which are outside the development objects at the present, but are promising for the future. This paper describes the achievements in fiscal 2000. In the hydrogen manufacturing method using natural gas as the raw material, but not generating carbon dioxide, a method using plasma has the hydrogen conversion rate of more than 90%, capable of providing carbon black with added value. On a hydrogen selective enzyme hydrogenase sensor, verification was given on its sensitivity and response speed, but the discussion was interrupted because of difficulty in obtaining the enzyme. Naphthenic hydrogen storage and transportation media (easy in hydrogenation and dehydrogenation) were discussed, whereas the reaction promoting effect was identified in both of the super heating liquid film process and the membrane reactor system. Enhancement in output and efficiency may be anticipated if hydrogen-rich reformed gas is obtained by reforming methane (natural gas) by utilizing waste heat from a gas turbine of several MW capacity. Hydrogen liquefaction technologies using the magnetic freezing process was discussed as the fundamental research assignment, wherein fiscal 2000 has studied the basic design and optimal magnetic materials.

This paper studies a concrete plan to introduce a new database system of Research Institute of Innovative Technology for the Earth (RITE) which is necessary to promote the industrial technology development contributing to solution of the global environmental problem. Specifications for system introduction are about maker selection, operation system, detailed schedule for introduction, etc. RITE inhouse database has problems on its operation system and its maintenance cost, and is apt to be high in a construction cost in comparison with a utilization factor. Further study is made on its introduction. Information provided by the inhouse database is only the one owned by the organization, and information outside the organization is provided by the external database. The information is registered and selected by the registerer himself. The access network is set by personal computer network at the beginning and is set to transit to INTERNET in the future. For practical construction of the system, it is necessary to make user`s detailed needs clear for the system design and to adjust functions between hardware systems. 32 figs., 9 tabs.

This paper describes research on peripheral technologies for hydrogen. For the cost of manufacturing hydrogen from different primary energies, coal gasification could be the lowest at the present time. In the nuclear power field, the thermo-chemical method and the water electrolysing method may be assumed, but they depend greatly on future technological development. Particularly the water electrolysing method is dependent on electric power cost. In the hybrid method, hydrogen is obtained from electrolysing reaction with water of sulfur dioxide derived by paralyzing sulfuric acid (oxygen is also generated). The method requires two forms of energies, heat and electric power, whereas combination with a very high temperature reactor (VHTR) is being discussed as a heat source. This method may not be said greatly more advantageous than the direct water electrolysis, but may have future possibility. Hydrogen manufacturing utilizing living organisms is an interesting matter in terms of science and engineering, with a large number of research achievements beginning to appear. Expectation is drawn on the mechanism based on co-work of photosynthesis and a hydrogen generation system, alga and bacterium strain search, separation, cultivation, and applied research and development. Research is also under way to obtain hydrogen by converting photo-energy by using an electrochemical photo-cell utilizing semiconductor electrode to electrolyse water (color sensitizing) (NEDO)

Validation researches have begun about the interrelationship between systems and human beings using a virtual-reality plant environment. This article introduces some recent studies about the human interface in an operation control system in a virtual-reality environment. The evaluation of a system from the viewpoint of ease of use is called a usability test, to which a psychological protocol analysis is applied for finding out problematic points by carefully observing the operator actually operating the system. For instance, in a boiler plant simulator constructed for DCS training, the operator is given some tasks, such as the prediction as to how a certain event will develop, probing of the cause of anomalies, and execution of related operations. Video cameras are installed at various spots for the minute observation of facial expressions and behavior of the operator, and the operator`s recognition, thought, behavior, and utterances, expressed by the operator facially or verbally, are recorded and analyzed, and the results are utilized for system improvement and operator training. 3 refs., 2 figs.

In the present paper, an attempt is made to develop an effective EHD enhancement technique for condensation heat transfer of steam around a horizontal finned tube. The main idea in the present study is to reduce the power consumption by using a partially coated electrode, and the experimental data of heat transfer coefficients and flooding angles are presented. The result indicates that, by using such an electrode, the enhancement ratio keeps almost the same level with that of a bare electrode but the power consumption can be markedly decreased. Within the present experimental range, the condensation heat transfer coefficient on the finned tube with the partially coated electrode reaches a value about 3 times larger than that without electrode. In addition, a model in presented for the EHD effect on the flooding angle and it is confirmed that the prediction from the model is in good agreement with the experimental data. (author)

This study aims to present the psychometric properties of the Portuguese version of the Positive Valuation of Life Scale (Lawton et al. in J Aging Ment Healt 13:3-31, 2001). Sample included 207 community-dwelling elders (129 women; M Age = 77.2 years, SD = 7.5). The data collection included the translated and adapted Portuguese version of Positive Valuation of Life Scale, Life Satisfaction Index Z, Meaning in Life Questionnaire and Geriatric Depression Scale. From exploratory factor analysis, two factors emerged, existential beliefs and perceived control, explaining 49 % of the total variance. Both factors were positively related with meaning in life and life satisfaction and negatively related with depression (p 0.75). The Portuguese version of Positive VOL Scale represents a reliable and valid measure to capture the subjective experience of attachment to one's life. The two-factor structure is an update to Lawton's previous work and in line with findings obtained in the USA (Dennis et al. in What is valuation of life for frail community-dwelling older adults: factor structure and criterion validity of the VOL, Thomas Jefferson University, Center for Applied Research on Aging and Health Research, 2005) and Japan (Nakagawa et al. in Shinrigaku Kenkyu 84:37-46, 2013). Future research is required to investigate VOL predictors and the potential changes toward the end of the life span.

Two kinds of typical environmental learning methods(direction and distance learning and route learning) were conducted experimentally as methods of environmental cognition in unfamiliar areas. Then, aspects of maintaining the sense of direction in grasping space structure of the area environment as well as concrete alternative wayfinding behaviors considered to be behavioral indexes for cognitive mapping were investigated. At the starting point, instruction related to the direction was given to P group, and that related to the route was given to M group. As a result, both groups decided the direction or found the alternative route according to the obtained information. The P group decided the direction properly by grasping the whole directional relations of the area and space structure of the route there. However, it was difficult for them to find the alternative route after restructuring the relations between specific points of the route. Concerning the motor relevant representation of the M group by time-dependent understanding of the route, continual occurence of perceptual characteristics on the way was worth noticing. 13 refs., 8 figs., 6 tabs.

We measure the distribution of activation locus of brain cortex area and its time-sequence against various kinds of stimulus by using the fMRI that can visualize directly brain activities. Next, we try to make a simulation model of the information processing system of brain, and aim at establishment of new evaluation index for environment-human interface based objectively or quantitatively on brain activity data. we challenged to examining quantitatively brain activities by using functional MRI instrumentation technique. We made a effort to acquire functional MRI technique by repetition of pilot studies, and were successful in visualization of visual cortex (primary sensory area). In the latter period, sensory areas whose function had not been studied sufficiently and higher functional areas of brain which related to memory, attention and emotion were studied. The identification of action locus of gustatory area was tried using functional MRI studies. In studies about the ability of spatial attention, experiments elucidating locus participating in space perception and attention and its function were advanced. It was suggested that activation locus of brain was different between a color-form matched stimulus and a mismatched stimulus. The MRI measurement added the information of musculoskeletal system to the current analysis of human body configuration and gesture character, and a more detailed analysis of human body became possible. This is, an useful analysis was suggested by a plan of shoes pattern. (NEDO)

In this study, the planar laser-induced fluorescence (PLIF) technique was used to measure the mean size and size distribution of diesel spray particles. The fuel used was n-tridecane mixed with 1 wt% N, N, Nprime, Nprime-tetramethylparaphenyenediamine (TMPD). The light source used to excite the TMPD in the fuel was a secondary harmonic of a ruby laser-light sheet. A highly magnified image of the fluorescence from TMPD was taken by a 35 mm still camera with magnified optics, and the mean particle size and particle size distribution of the fuel spray were determined by processing the images of fuel particles printed on paper. First, the accuracy of this method was confirmed by comparison with results of Phase Doppler Anemometry for fuel spray of an air-assisted gasoline injector. Then, for the diesel spray, the effects of injection velocity, ambient pressure, geometric configuration of nozzle hole (i.e., nozzle hole diameter and nozzle hole L/D) and of measurement points on the fuel particle mean size and size distribution in a high-pressure vessel at atmospheric temperature were investigated. The results showed that the small size particles increase in number with increasing injection velocity. At higher injection velocity, seem to atomize more actively. With increasing ambient pressure, the mean particle size increases. A reduction in nozzle diameter resulted in no improvement of atomization in this study. Also, the mean particle size in the downstream region of the spray is larger than that in the upstream region of the spray. 16 refs., 19 figs., 3 tabs.

It was previously found that the increase of slurry temperature provides a significant effect of slurry viscosity reduction for the coal slurry with high concentration of 50 wt%. To investigate the detailed influence of slurry temperature for the coal slurry with concentration of 50 wt%, influence of temperature on the successive change of apparent viscosity was observed at the constant shear rate. When the concentration of coal was increased from 45 wt% to 50 wt%, viscosity of the slurry was rapidly increased. When heated above 70{degree}C, the apparent viscosity decreased during heating to the given temperature, but it increased successively after reaching to the given temperature. The apparent viscosity showed higher value than that of the initial viscosity. The coal slurry with concentration of 50 wt% showed the fluidity of Newtonian fluid at the lower shear rate region, but showed the fluidity of pseudo-plastic fluid at the higher shear rate region. The slurry having high apparent viscosity by the successive change showed higher apparent viscosity with increasing the higher even by changing the shear rate. 1 ref., 4 figs.

Surveys and studies were conducted concerning a demonstration plant for establishing the technology of integrated coal gasification combined cycle, and the fiscal 1995 results are compiled. In this fiscal year, a demonstration plant conceptual design was prepared for assuring smooth transition from a pilot plant to a commercial plant. The design followed the system employed at the Nakoso pilot plant for its gasification power generation. It was decided that the gasification furnace be of the air-blown (oxygen enriched) 2-stage entrained bed type, that the desulfurization system be of the dry type 2-stage fluidized bed type, the dedusting system be of the dry type granular bed type (moving bed type), that the combined cycle power facility be derived from the commercialized gas turbine, and that the cycle of the steam system agree with the integrated coal gasification combined cycle system now under discussion. Studies were made, which covered heat efficiency (generating end/sending end), heat/matter balance, process flow, gas turbine/steam system optimization, comparison in performance with a pilot plant with its dimensions increased, estimation of the performance of each of the facilities, estimation of the construction cost, calculation of the generation cost, environmental friendliness, operating characteristics, acceptable coal types, and the like.

A new separation and purification method for lactic acid from fermentation broth is proposed by which poly-lactic acid produced from unpurified lactic acid is catalytically depolymerized into lactide fractions then further purified into lactide. In the present study, thermal depolymerization catalysts were investigated for commercial use. Iron catalysts, especially metallic iron, and ferrous oxide and lactate, were found to provide almost the same catalytic activity and lactide composition in depolymerization products and those in tin octoate and antimony oxide catalysts. Ferrous oxide was also applied to depolymerize poly-lactic acid derived form unpurified lactic acid to compare catalytic activity and lactide composition and was confirmed to show results similar to those of pure polymer. Based on these findings, it is concluded that iron catalysts can be used commercially. Furthermore, catalytic depolymerization of poly-lactic acids with different molecular weights were studied. Polymers with Mw 5,000-10,000 were found to be better for production of lactide, based on the behavior of depolymerization and lactide content in the product. 5 refs., 9 figs., 1 tab.

A study was made of the periodic steady state of the annual cycle solar energy system with seasonal heat storage at a practical operation. Cold heat in winter and warm heat in summer are stored in the seasonal storage tank, and these are each used in shift until when demand for cold/warm heat appears. Moreover, gap in quantity of cold/warm heat going in/out of the heat storage tank during a year is filled by natural energy such as solar energy, so that the system can be operated in annual cycles. Studies were conducted of the periodic unsteady term and the problem on lowering of performance during the term such as the periodic unsteady term of water temperature inside the seasonal heat storage tank and temperature of the soil around the storage tank, and the level of lowering of performance during the term, necessity of additional operation/control at the start of operation and aged deterioration of the system. Within the assumption, even if starting operation in any time of the year, the system could show the performance almost expected from the first operation year with no additional system operation and control required only at the start of operation. It is thought that the heat source selection control of heat pump largely contributes to this. 4 refs., 5 figs., 3 tabs.

It was intended to darify long-term performance of a secondary hydrogenation catalyst used for about one year in a 50t/d brown coal liquefaction pilot plant built in Australia. A catalyst used for about 3,400 hours in the pilot plant was used to perform a life test of 7,800 hours in total to investigate the catalyst deactivation behavior, ashed metal and carbonaceous material deposition behavior, and changes in catalyst properties. A catalyst is considered to deactivate mainly because of deposition of carbonaceous materials on the catalyst in the initial stage of reaction and accumulation of alkaline metals (Na and K). The catalyst activity is estimated to reduce to about half the initial activity in about 1,000 hours, but it was found that the activity reduces and the properties change very little thereafter. From the fact that changes in selectivity to reaction associated with reduced activity and in product properties are small, and so are in the apparent activation energy, it was made clear that Cu-Ni-Mo/Al2O3 catalyst can be used for about one year. 3 refs., 9 figs., 1 tab.

The secondary hydroprocessing process in the two-stage hydrogenating liquefaction equipment under development at Nippon Brown Coal Liquefaction Company uses a fixed bed system. To elucidate causes of catalyst activity degradation related therewith, catalyst used for about 1000 hours in a S -t/d pilot plant was collected to investigate deposition behavior of cokes and ashed metals and changes in catalyst properties. The catalyst is made of Ca-Ni-Mo/Al2O3, which was recovered from baskets placed in each layer in a reactor, washed in a predetermined manner, dried, and analyzed. In addition, in order to investigate remaining activity, 1-methylnaphthalene was hydrogenated, and deashed oil (DAO) was hydrocracked. The result may be summarized as follows: The major cause for the catalyst activity degradation is deposition of carbonaceous materials and ashed metals on the catalyst; and especially alkali metals (Na and K) were considered to be the major cause for the catalyst deactivation with time. 2 refs., 8 figs.

A model house was simulated to reduce the consumption and peak demand for the photovoltaic power generation system, and solar heat air heating and hot water supply system in the solar house. As a type of construction, both wooden construction and reinforced concrete (RC) construction were selected with a total floor area of 125m{sup 2}. All the rooms were equipped with an air conditioner by heat pump from the air thermal source. A solar heat floor heater was simultaneously installed on the first floor. The hot water supply load was 4.8MWh per year. A commercial grid-connected on-site system was applied to the photovoltaic power generation with a 20m{sup 2} wide monocrystalline Si solar cell panel. As for the fluctuation in power load, the peak at the time of rising is more reduced in the RC house than in the wooden house, because the former is smaller in temperature fluctuation than the latter during the intermittence of air conditioning (as per the specified operational schedule). Therefore, the power is more leveled off in the former than in the latter. Between both, difference was hardly made in energy consumption per year. The ratio of dependency was 47% upon the photovoltaic power generation system, while it was 50% and 77%, under the air heating power load and hot water supply power load, respectively, upon the solar heat air heating and hot water supply system, so that both systems were considerably effective in saving the energy. 5 refs., 7 figs., 1 tab.

This paper describes thermodynamic properties of HFC refrigerant mixtures for Lorentz-cycled new generation air-conditioning equipment. Equipment has been completed for simultaneous measurement of density and vapor-liquid equilibrium property, accurate measurement of latent heat of vaporization, and accurate measurement of specific heat at constant pressure in liquid phase. Final adjustment and preliminary measurements are currently conducted. Through analytical investigation using actually measured data of thermodynamic properties of HFC refrigerant mixtures, five state equations were obtained, i.e., modified Peng-Robinson state equation which can reproduce the vapor-liquid equilibrium property of refrigerant mixtures, modified Patel-Teja state equation, Helmholtz function type state equation which is applicable in the whole fluid region of refrigerant mixtures, and so on. An evaluation test equipment has been fabricated as a trial for Lorentz-cycled air-conditioning equipments using HFC refrigerant mixtures, and demonstration test is conducted to confirm the validity. 9 refs., 5 figs.

The reaction velocity constant of coal or the distribution of products in a high-pressure hydrocracking process of coal are found not to be affected by the temperature rise rate. The liquefaction of coal using CO and water is analyzed using a high-pressure differential thermal analyzer. The hydrogen gas generated during the water gas reaction reacts with CO for the formation of alcohols, carbonic acid, etc. The reaction rate is found to be higher when the specimen contains more oxygen. When coals greatly different from each other in terms of thermolytic reactivity, caking property, and intersolubility with medium oils are mixed, synergistic effects are exhibited, positive when active hydrogen supply is abundant and negative when it is short. In the case of the Hokkaido coal which contains 73.0-87.4% carbon, the grain diameter does not affect the liquefaction rate when the coal is crushed to the 48-mesh size approximately. Reaction velocity in direct liquefaction does not relate to hydrogen pressure. Asphaltenes in coal liquefaction are produced at the beginning of reaction, to be reduced in molecular weight due to cleavage of methylene crosslinks with the progress of reaction. Studies are conducted in a 0.1t/d-capable bench plant about liquefaction reaction characteristics and coal liquid properties, and chemical structures. (NEDO)

A numerical model was prepared to express fields and size of hydrogen energy introduction in Japan's energy systems in the future. Dividing Japan into 13 weather sections, one to two energy bases (import and secondary production bases in coastal areas) were assumed on each section. Secondary energies produced in these energy bases are transported to intermediate bases, from which the energies are distributed into cities and consumed. For the purpose of simplification, final consumption departments are hypothesized to exist in these intermediate bases. Parameters that characterize the flows on networks in the processes of supply, distribution, production, storage, transportation and utilization are divided largely into energy efficiency and cost of the processes. The amount of energy demand in each final consumption department was defined as an amount to maximize the expected effects as a result of having satisfied the demand. The result of trial calculations revealed that, as long as the hydrogen to be introduced is limited to hydrogen produced via electrolysis using thermally generated power, the hydrogen introduction into the future energy systems is difficult in terms of economic performance.

Concerning the research and development of environmentally-friendly combustion technologies that had been conducted for six years beginning in 1992, analysis and discussion were made by a special committee dedicated to the evaluation of the efforts, and the outcome is stated. In the study of zeolite-base catalysts, a highly active catalyst was developed which assumes a multilayer structure of mordenite, etc., with titanium introduced thereinto using an NO-selective reducing catalyst. As for metal complex oxide-base catalysts, various catalysts high in activity were developed, based on saponite which is a laminar, clayey compound. As for alumina-base catalysts, details were learned of the reaction mechanism and catalysis activation sites and, helped by the findings, a silver-supporting alumina catalyst was produced. In the study of direct decomposition type NOx removing catalysts, a success was achieved in causing NO to be decomposed with high selectivity in an oxygen atmosphere by use of new-type electrodes, functional layers, and solid electrolytes. In the field of catalytic combustion, a PdO-Pt/Ba-Al2O3 catalyst was developed, which is to serve for a hybrid type catalytic combustion method. 19 refs., 112 figs., 25 tabs.

Three kinds of coals with different rank of 76, 85 and 87C% were hydrocracked to study the specific reaction behavior of four kinds of 1coal liquefaction catalysts such as CuCrO4, Fe2O3+S, MoO3-TiO2 and MoS3-Al2O3. The reaction was conducted without any solvent to find out the specific phenomenon of each combination of coal and catalyst, and terminated at the point where nearly 30% of an initial amount of coal is converted to benzene-soluble. The products were separated by GPC into four fractions, and their average molecular weights and intrinsic viscosities were measured to study characteristics of each combination. As a result, the molecular weight distribution was obviously dependent on the combination of coal and catalyst, and no specific relation was observed between the molecular weight and intrinsic viscosity. The molecular of each fraction had a bar shape with an elliptic section indicating no apparent correlation with the molecular weight. 3 refs., 1 figs., 2 tabs.

To improve the tenacity and reliability of ceramics, the fiber reinforced ceramics composites compounding high strength long fibers and ceramics have been investigated. In this study, carbon fibers were selected as reinforcement fibers. The hexagonal boron nitride (hBN) was selected as a matrix having the plastic deformation performance. To intend to control the composition of the fiber/matrix interface, composites were created by adding polysilazane which was an organic Si (Si3N4) source. Relationships between the condition of interface of each phase and the high temperature mechanical properties were examined by changing the fabrication condition, to grasp the technical problems, such as the optimization of fabrication condition. Knowledge on the fabrication of long fiber reinforced ceramics composites was obtained including the arbitrary control technology of interface consistency of ceramics composites for super high temperature structures. The carbon fiber reinforced hBN composites developed in this study have excellent strength up to 1,500 centigrade and fracture energy, and they are new prospective materials as well as C/C composites. 4 refs., 37 figs., 13 tabs.

Information systems, mainly aided by computers, are becoming increasingly important, contributing to development of wide areas of societies and economics, to begin with. However, few developing countries have established sufficient information systems, in spite of their strong desires to do so, which will further widen the gap between them and advanced countries, where these systems are acceleratedly advancing. Given these situations, Center of International Cooperation for Computerization (CICC) has been implementing various projects for providing assistance to and cooperation with oversea countries which are trying to develop information systems. This report summarizes the project, which CICC has been commissioned by NEDO as part of the cooperation programs, for manufacturing technology supported by advanced and integrated information system through international cooperation. It outlines the research cooperation memoranda NEDO has concluded with Indonesia, Malaysia, Singapore and Thailand, and the authorities of China, Indonesia, Malaysia, Singapore and Thailand. (NEDO)

This paper explains concepts of aircraft engine afterburner, and describes history of afterburner study, and describe the result of major research items. An afterburner is located down stream of a fan, compressor, burner, and turbine in a jet engine. Its basic principle is that fuel is injected into turbine exhaust and fan air flows from an fuel injector, ignited by a spark plug using oxygen remaining in the exhaust gas flow, burned and flame-held by a flame stabilizer. The combustion gas of high temperature (1,700 to 1,800 {degree}c) thus generated is jetted out from an exhaust nozzle to increase the thrust. The prototype afterburner is featured by adoption of a mixed type fuel injection system that provides wide stable combustion range, and flame stabilizer with a scoop aimed at improving the ignition performance and combustion efficiency. A confirmation test verified smooth ignition and wide air to fuel ratio for stabilized combustion. 4 refs., 16 figs.

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)

Cable-stayed bridges are being constructed increasingly and their maximum effective span length is becoming longer to the extent that it is about to reach the limit, thereby diagonal members which, by nature, tend to vibrate become much longer, hence problems concerning vibration have drawn attention. In this article, regarding vibration insulating rubber for absorbing vibrations to be set at an anchorage of diagonal members, a new mechanism has been invented and its analysis as well as demonstration experiment have been conducted. This mechanism is based on the concept that the vibration insulating rubber has been set beforehand at the time of installing the diagonal members, adheres to the diagonal members immediately after the diagonal members are stretched, but its adherence is released simply when tension adjustment is needed, and the spring constant of the rubber can be calculated simply within the range of practical use. The results obtained from the above analysis and demonstration experiment are as follows; it is necessary to set vibration insulating rubber in the vicinity of the anchorage of diagonal members in order to absorb vibrations of the members and the method to make its setting simple and secure has been confirmed. Also the calculation method of spring constant of vibration insulating rubber necessary for estimating the secondary bending stress of diagonal member has been confirmed, thereby designing of vibration insulating rubber has become easy. 8 refs., 14 figs., 2 tabs.

The influences of fish (goldfish) on water quality and nutrients cycle (carbon, nitrogen, phosphorus) were investigated during 39 days in the summer of 1993, using six outdoor experimental ponds (36 m{sup 3}) with the same water residence times and nutrient inputs. Blue-been algae dominated the ponds with fish. Compared with ponds without fish, the ponds with high densities of fish had standing stocks of zooplankton and macrozoobenthos nearly one order of magnitude lower, about twice the concentrations of chlorophyll a and twice the rate of primary production. Settling rates of particulate substances in the high density ponds were nearly half those observed in ponds with no fish. The processes of sedimentation and exchange with air played important roles in the nutrient budgets as well as the in- and outflows and the changes in nutrient standing stocks. The high concentrations of chlorophyll a in the fish ponds were attributed in part to the lower zooplankton grazing pressure and in part to the higher nutrient concentrations due to lower settling rates and rapid nutrient recycling between biomass and dissolved components. 28 refs., 8 figs., 6 tabs.

Recovery of gold with ion exchange resin from leaching solution by acidothioureation, and elution of gold from ion exchange resin with gold were studied experimentally. As the result of batch adsorption experiments of Au(TU){sub 2}{sup +} into various kinds of ion exchange resins, strong acidic cation exchange resin was most suitable, and gold was fully adsorbed into such resin in the pH range from 1.2 to 2.0 without any effects of thiourea in the leaching solution on adsorption of gold. As the result of batch elution experiments in various kinds of eluates, copper was eluted in HNO{sub 3}(1 N) + H{sub 2}O{sub 2}(1wt%) elute, both iron and zinc in NH{sub 4}NO{sub 3}(0.5 M) elute, and gold in Na{sub 2}S{sub 2} O{sub 3}(0.05 M) elute resulting in the recovery of gold. As the result of column elution experiments, Amberlite 200C was most effective among some ion exchangers used for recovery of Au(CS(NH{sub 2}){sub 2}){sub 2}{sup +}. 16 refs., 15 figs.

Studies were carried out to develop a high-performance ceramic heat exchanger for ultra high temperatures using a fluidized bed. In the former study, Heat transfer coefficient had been improved by applying fluidized bed to the heat exchanger for high temperature with smooth ceramic tubes. In this study, finned ceramic tubes were applied instead of smooth tubes for more improvement of heat transfer and experiments were performed on condition that the maximum bed temperature was 1100degC. Fluidization remained stable and the bed temperature uniform in the bed similarly as the case of smooth tube. A heat transfer coefficient of finned tube was evaluated and it was improved about 3 times as large as that of smooth tube. The performance of the heat exchanger was also evaluated using temperature efficiency and exergy efficiency. 4 refs., 11 figs., 1 tab.

Studies are conducted about anthropometry using a computer mannequin for assessing the compatibility of virtual commodities and environments, fabricated by CAD (computer-aided design) or the like, with human beings, and the fiscal 1999 achievements are compiled. In the study of multidimensional equations of correlation for shape estimation, calculation of basic human model dimensions using 43 measurements has become feasible. For the construction of a human model using a computer mannequin, joint positions and distances between joints have to be determined using data which are measurements that cover human model surfaces. Such necessitates a study of shape estimating algorithm, and a basic physique calculation module and a shape estimation module have been developed. Verification is conducted using a computer mannequin, and it is found that much information is quantitatively determined prior to the manufacture of real goods, the said information involving the mechanism of a chair and the behavior of a human being in it, and the relations of the human behavior with peripheral equipment.

The current fiscal year has surveyed and studied to have coal liquefying plants and the different existing industrial plants put into a complex. When structuring specifically the commercialization of the coal liquefaction process, some kind of complex formation is required from its business size and economic performance. From this viewpoint, the current fiscal year has performed discussions with economic performance as an additional item on forming a complex with (1) petroleum refining industry, (2) iron and steel making industry, (3) chemical industry, and (4) electric power generating industry. Investigations were also carried out on the feasibility of systems thereof and the technological problems therein. In the subject (1), if coal liquefied oil is introduced into a petroleum refining process, and both oils can be mixed, construction cost of the coal liquefaction plant and the oil cost per barrel may be decreased. In the subject (2), forming a complex of a converter integrated steel mill having a crude ore production scale of 600,000 tons a year with a coal liquefaction plant having a scale of 30,000 tons a day will present problems in the balance of facility size and quantity. In the subject (3), producing chemicals as by-products as a result of complex formation will enhance the economic performance of the coal liquefaction plant. In the subject (4), a complex formed plant is more advantageous in load variation than ordinary power plants. (NEDO)

This paper summarizes study trends mainly in CO2 fixing processes. Underground CO2 storage is a most promising method because it can fix a huge amount of CO2 and has low effects on ecological systems. Storing CO2 in ocean includes such methods as storing it in deep oceans; storing it in deep ocean beds; dissolving it into sea water; neutralizing it with calcium carbonates; and precipitating it as dry ice. Japan, disposing CO2 in these ways, may create international problems. Separation of CO2 may use a chemical absorption process as a superior method. Other processes discussed include a physical adsorption method and a membrane separation method. A useful method for CO2 fixation using marine organisms is fixation using coral reefs. This process will require an overall study including circulation of phosphorus and nitrogen. Marine organisms may include planktons and algae. CO2 fixation using land plants may be able to fix one trillion and 8 hundred billion tons of CO2 as converted to carbon. This process would require forest protection, prevention of desertification, and tree planting. Discussions are being given also on improving power generation cycles, recovering CO2 from automotive exhausts, and backfilling carbons into ground by means of photosynthesis. 23 refs., 7 figs., 1 tab.

With an objective to clarify causes of deactivation of catalysts used in brown coal liquefaction process, discussions were given on catalysts recovered after use of 3400 hours as to their behavior of accumulating ash metals and carbonaceous substances, changes in the catalyst properties, and remaining activity. The catalysts used were Ca-Ni-Mo/Al2O3. Metals in the catalysts were quantitatively analyzed using ICP emission spectral analysis and atomic absorption analysis, and the C-amount using a CHN coder. The surface area was measured using the BET process and the pore volume using a porosimeter. The remaining activity in the used catalysts was evaluated by modelled hydrogenation of 1-methylnaphthalene. The results may be summarized as follows: Metals deposited on the catalysts are Mg, Ca, Fe, Na, Si and K, identically with the case of 1000-hour used catalysts; carbonaceous mass on the catalysts would range from 10% to 15%; the catalyst surface area and pore volume decrease with increasing carbonaceous matter accumulation; and hydrogenation activity was found decreased in the model hydrogenation, which should be because the activity has correlation with alkaline metal accumulation, and the metals enter fine pores to poison activity points. 3 refs., 6 figs.

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

Passive earth pressure exerts a great influence on the stress and deformation of earth retaining walls in braced excavation. To calculate this pressure, conventional ultimate earth pressure equation, or Rankine-Resals and Coulomb`s equation, are currently applied respectively to cohesive and sandy soil. However, these intentional equation to determine passive earth pressure do not adequately take into account the excavation width during work and the shearing resistance on the earth retaining wall surface. This paper deals with cohesive soil only, deriving a calculation equation for passive earth pressure, which takes into account excavation width and the shearing resistance of the earth retaining wall surface. Then, constants in this equation are determined using the calculation results obtained from the finite element method with blasts-plastic elements. The calculation results are also compared with measured values in the model test in order to check the applicability of the calculation equation for passive earth pressure thus obtained. Finally, this paper proposes a practicable calculation equation for passive earth pressure. 13 refs., 10 figs., 10 tabs.

It was found, as published in the previous paper, in the investigation of radiation temperature, radiosity coefficient, their wave-length dependence and the dispersiveness of these parameters about the surfaces of various kinds of material that the assumption of gray body approximation does not hold in the surfaces of metal and part of nonmetal. In the present work, applicability of pseudo-gray body approximation to the metal surface in a system surrounded by black body surfaces was studied in consideration of directivity of emissivity and reflectance while, in actual, a measuring angle of 15 degrees giving a small directivity effect was used based on experimental results. As in the previous paper, three kinds of sensors different in the detectable wave-length range were used to evaluate the radiation temperature, emissivity, radiosity coefficient, and their dispersiveness. The experimental results proved the applicability of pseudo-gray body approximation. 3 refs., 18 figs., 2 tabs.

The power transmitting mechanisms for laminated belts were studied to analyze belt tension in each band of the ring of metal V-belts. A numerical model consisting of linear springs and frictional elements was proposed. The present model was experimentally proved. It is revealed based on the numerical results that each band shares the ring tension equally when the coefficients of friction for bands and a pulley are the same while the first band must support more when the coefficients of friction between two bands are lower than that between a saddle surface of the block and the inner band. 4 refs., 9 figs.

This paper studies the method of predicting and evaluating the motion sickness incidence from subject`s facial expressions during the whole-body exposure to oscillations. The facial expressions are recorded with a video camera which can measure them without invasion physiologically and mentally. Facial parameters, which are considered to relate to the motion sickness incidence, are selected, measured and analyzed quantitatively, and a method of evaluating the motion sickness incidence objectively from the facial expressions is proposed. Three facial expression parameters now selected to evaluate the motion sickness incidence are brow width, eye opening and mouth opening. It was clarified that the motion sickness incidence could be expressed joining the above parameters together. This paper consists of three sections, viz. Oscillation experiment for ride-quality evaluation, Measurement and analysis of facial expressions, and Modeling for evaluating facial expressions. 11 refs., 5 figs., 5 tabs.

The expression and physiological function of two transcription factors, GATA-2 and Xmsx-1, in amphibian embryos has been analyzed. The expression of these mRNAs in embryonic cells were firmly regulated by the BMP-4 signaling, that plays a central role in the formation of ventral tissues. The microinjection studies of GATA-2 RNA into embryonic cells suggested that this factor functions in two adjacent germ layers, mesoderm and ectoderm, to participate in blood cell formation in ventral area of embryo. Embryos injected with Xmsx-1 RNA, but not with GATA-2, in dorsal blastomeres exhibited a ventralized phenotype, with microcephaly and swollen abdomen. Thus, Xmsx-1 is a ventralizing agent. However, on the basis of molecular marker analyses, Xmsx-1 did not promote erythropoietic differentiation, but promoted muscle tissue formation. It has been concluded that Xmsx-1 si a target transcription factor of the BMP-4 signaling, but possesses a distinct activity on dorso-ventral patterning of mesodermal tissues. (author)

The paper studied a system to effectively use unused and low-grade thermal energy (cold heat and hot heat) in the Tokyo-Yokohama seaside area. For transportation of thermal energy, the batch transportation, that is, off-line system was discussed which uses insulated tank loaded barges and railroad freight trains. Thermal energy supply sources are 1) 0.3 million kW class thermal power plant, and 2) LNG storage base of 3 million ton/year class. Thermal energy users are Tokyo (Haneda) Airport D.H.C. (District Heating/Cooling Co.), MM 21 D.H.C. and Shin-Kawasaki D.H.C. The cold heat energy supplied to these three is about 1.5 million Mcal/daytimes300 days/year, and the hot heat energy supplied is about 1.33 million Mcal/daytimes150 days/year. Cold heat is obtained from seawater after the LNG vaporization, and hot heat from heat extracted from thermal turbine. Subcooled ice was selected for cold heat medium, and PCM-120A for hot heat medium. For batch transportation, an STL heat storage system is used which transports plastic capsules sealed with heat medium. Oil saving of 62,000 tons/year and CO2 reduction of about 53,000 tons/year can be expected. 85 figs., 98 tabs.

As a part of the studies on practical surface temperature measurement by infrared radiometer, some basic characteristics of an infrared radiometer were studied by using three kinds of sensors with different detectable wave lengths. Specimens allowable for gray body approximation such as mortar, graphite and carbon fiber composite material were tested at a practical ambient temperature of 293 K. As a result, the difference between a radiation temperature in consideration of reflection and that derived from an emissivity increased with a decrease in emissivity, and the deviation of an emissivity derived from a radiosity coefficient increased at 20 K or less in difference between a specimen surface temperature and ambient one. Each radiosity coefficient measured by each sensor also fairly agreed with each other. The deviation of a radiosity coefficient was relatively small indicating a good agreement between theoretical and experimental data, while the difference between emissivity and radiosity coefficient deviations decreased with an increase in specimen surface temperature. 3 refs., 10 figs., 1 tab.

The oxygen electrode is important as the base electrode for water electrolysis and fuel cell, but to move it, overvoltage (activated energy) in addition to equilibrium voltage is necessary, which leads to the lowering of energy efficiency. By forming the active spot by ion implantation, the lowering of overvoltage was studied. The implantation of Ru{sup +} ion in Ruthenium dioxide thin film electrode reduced the oxygen generating overvoltage by 15-20mV. Even in the oxygen reduction, activity was also increased. The chemical composition of thin film does not change by ion implantation. The increase in activity is based on a physical change which is called the surface defect formation. The layer of ion implantation is composed of microcrystals, which is thought to contribute to the formation of any active spot. Ions were implanted in Pt electrode as a practical use material, and even in the oxygen reduction of Pt, a possibility of heightening activity by ion implantation was admitted even in the oxygen reduction of Pt. The generation of high activity oxygen by ion plantation and development of oxygen reduction electrode were established as one method as a rule. (NEDO)

This paper explains the results during fiscal 1998 of ion exchange membranes in the development of polymer electrolyte fuel cells. Studies were made on three kinds of standard and two kinds of experimental membranes selected among the Flemion membranes, which are perfluorosulfonic acid membranes made by Asahi Glass Co.,Ltd., and also on the Nafion membranes by Dupon as reference. As the resistance evaluation of the environmental cycle for the membranes, a temperature cycle test was carried out, with the characteristics measured such as moisture content, membrane resistance, mechanical properties, and gas permeability, so that the effects were examined of the temperature cycle on the membranes. Evaluation was also commenced on the water permeability, an important substance-moving characteristic of ion exchange membranes. In the evaluation of the characteristics of membrane-electrode assemblies, the environmental cycle test was performed by joining electrodes to membranes, with the evaluation similarly made as for the membranes alone. On the basis of a correlation between the water permeability and the cell performance, studies were made on the effect of thickness of the membranes on the cell performances. A continuous stability/durability operation of 3,500 hours was verified using Flemion R. As for membrane reinforcement, studies were continued on the cloth and fibril reinforcements as in the previous year.(NEDO)

Described herein are the final evaluation results obtained by the 7-year R and D project, beginning in the FY 1976, established by the national project system for developing the techniques for treating urban solid wastes. This project has developed a semi-wet type selective crushing/sorting unit for sorting the wastes, and established the elementary techniques for recycling the wastes into various products, e.g., compost, pulp, combustible gases, aggregates, methane gas, or fuel oil. Two types of total treating systems, in which these elementary techniques are integrated, have been developed; one is to recover materials and the other energy. They can comprehensively, efficiently treat the wastes, adapting themselves to various situations. Pyrolysis which discharges reduced quantities of flue gases is adopted. Waste water is treated, mainly by biological treatment which is supported by the conventional methods, e.g., coagulation and adsorption. The cost estimation results indicate that the total system developed by this project can compare favorably with the conventional incineration system under general conditions, at a capacity of 300 t/d or more, when taking into consideration the secondary effects brought by the recycling/reutilization. This system is commercially feasible, when it meets with local characteristics, e.g., garbage collecting systems, market values of recycled resources, treatment/disposal conditions, and natural and social environments. This project has sufficiently achieved the original objectives. (NEDO)

The purpose of this research is to grasp the policy of the oil sand resource countries, the properties and existing conditions of the resources, effects of the oil sand resources on a long term energy supply/demand, etc., and to clarify the meaning and position of the researches on the development of oil sand resources in the future energy policy of Japan. The quantities of oil sand resources are mostly in the process of investigation except Alberta province of Canada and are estimated to be two trillion barrels. The quantity for which strip mining is possible is about 90 billion barrels, which are mostly located in the Athabasca region. The oil sand holding countries take a policy of positively developing oil sand. No barriers are particularly provided against the introduction of foreign technology and capital. Where the prospects are possible for the development of oil sand are Canada and Venezuela. R and D should be emphasized on the refining of bitumen and the extraction method within the oil reservoir. The investment per b/d is about 15-20 thousand dollars, which is likely to be more than twice as much as for the North Sea oilfields. The properties and quality of the synthetic crude oil are superior while the risk of exploitation is small; therefore, oil sand will be competitive with crude oil in the future. (NEDO)

In order to help discuss the system and environment improvement to promote freer flow of Japanese researchers, surveys and discussions were given on the actual status in America and European countries. In the U.S., results as independent researchers are demanded from the very early time under the severely competitive environment, wherein the fair evaluation of the results allows the researchers to step-up the positions and research environment to which the researchers are oriented. In Germany, a function to promote researcher mobility is available as a system, such as promotion of exchange with other sectors during researcher education course (the internship system at the fourth grade in a university, and power training and performance record building at the Max-Planck Institut during the long term of post-doctoral period before attaining a professor position), or prohibition of inviting university professors into the same faculty. The actual status of Japan not having high mobility of researchers has been caused by the system based on the lifetime employment, whose shortcomings include stiffness in personnel affairs, and reduction in activities of researchers due to aging.

For the cleavage of carbon-chlorine connection and decomposition of benzene rings which are hazardous causes of the environmental pollutants represented by dioxins, the photolysis of gaseous phase chlorobenzene used as a model compound was made using KrF and ArF excimer laser. The decomposition is high efficiency, and ArF shorter in wavelength can be compounded twice-four times as fast as KrF. It was found out that in the system where oxygen exists, carbon monoxide, carbon dioxide, acetylene, hydrogen chloride, etc. are produced as decomposition products. From the results of the gaschromatographical analysis, chlorine compounds were detected as solid phase decomposition products. However, by the oxygen existence effect and laser shorter wavelength effect, the formation of polychlorinated aromatics was controlled, and chlorine compounds were made non-pollutant together with the composition. It was indicated that the environmental clean-up technology using laser is effective for making low-concentration environmental pollutants non-pollutant, and it is a method to clean up the environment which has a wide range of the application field.

The fatigue test of specimens with a stiffener was carried out to examine the change in aspect ratio (crack depth/length) of fatigue cracks in a stress concentration field and residual stress field. The aspect ratio of surface cracks just after generation can be represented with the single virtual surface crack with the same value as K value at the deepest point considering an interference effect from near cracks. No discontinuous change in K value is found at the deepest point even during growth and combination of cracks on a surface. The change in K value at the deepest point is thus the criterion to represent growth and combination of surface cracks considering the interference effect. The change in aspect ratio of the typical single virtual surface crack linearly decreases with an increase in crack depth. The shape of surface cracks generating and growing in a residual stress field is more flat than that in no residual stress field. In addition, in a residual stress field, surface cracks are longer at the same crack depth, and fatigue lives are shorter. 7 refs., 12 figs.

The following were selected as themes necessary and important for the safety of the forthcoming hydrogen energy system, based on the fiscal 1974 document survey result, and the fiscal 1975 research results. First as for low- temperature storage of hydrogen, since safe discharge of hydrogen gas generated in a storage tank is important, gas motor discharging usually used for such transport tanks as tank lorry, and burn bond discharging suitable for discharge of a large amount of hydrogen were selected as test items. Next as for storage and transport of low-temperature hydrogen such as liquid hydrogen, a low-temperature control valve to control the amount of liquid hydrogen for transport was selected as a test item. Under the assumption of the model tests on the above 3 items in fiscal 1976, various studies and trial designs were made on concrete test equipment. The test plans were also prepared for some ones among them. (NEDO)

This research cooperation promotion project was implemented to develop techniques for preventing water pollution by waste water from pits in mines in China and thereby contributing to environmental preservation by studying to select optimum bacteria, culture the bacteria for high-efficient oxidation of iron, efficiently remove heavy metals from waste water, develop waste water treatment techniques with the aid of the iron-oxidizing bacteria, suitable for the mines in China, and develop techniques for recovering useful resources. The bio-aided waste water treatment process is a suitable method for treating waste water discharged from mining pits, in which ferrous iron present in waste water is oxidized with the aid of iron-oxidizing bacteria growing with ferrous ion as the energy source into ferric iron, which is precipitated at a low pH and removed in the presence of inexpensive calcium carbonate as the neutralizer. The pilot plant has been operating smoothly in a mode to treat waste water discharged from mining pits in Wushan Mine, almost satisfying the targets of treated water properties, i.e., pH: 0.5 or less, Cu: less than 0.5, Zn: less than 2.0, Pb: less than 1.0, Cd: less than 0.1, As: less than 0.5, Mn: less than 2.0, and SS: less than 70, all in mg/L except for pH.

This paper reports the result in fiscal 1995 of the study on PLD (pulse laser deposition) thin film formation process having been made since 1993. In fiscal 1995, the effect of irradiation of excimer laser and YGA(SHG) on ablation of aggregates of N2, CH4, Ar, Kr and Xe, and the effect of time-delayed irradiation of YGA(SHG) and KrF excimer laser on ablation of N2 aggregate were studied aiming at exciting ablation by cryogenic aggregate alone. Experimental results by a newly developed multi-laser excitation experiment equipment are as follows. Ablation was not caused by KrF excimer laser irradiation, while caused by YGA(SHG) irradiation. Ablation was caused by 1mm thick N2 or CH4 aggregate alone. Kr target was the most promising among rare gas solid targets expected as seed of ablation occurrence. Multi-irradiation showed a different ablation behavior as compared with single YGA(SHG) irradiation, and in some cases, multi-irradiation not increased scattering of particles. Time-delayed multi- irradiation (YGA(SHG) excitation after excimer excitation) was effective. 23 figs., 4 tabs.

The purpose of the present surveys and studies is to discuss positioning of new energies for the case of forming the energy mix for Japan, and measures to arrange the conditions to have the positioning take roots in the society. One of the assignments in the discussion is to propose a system intended of improving the economic performance and of harmonizing with the existing energy systems, by establishing an adequate hybrid system composed of new energies and the existing energies. The current fiscal year will propose a hybrid system for manufacture or composite utilization of 'new synthesized fuels'. Another assignment is to discover a method to analyze quantitatively and evaluate how much the energy supply security in Japan will be improved, what the economic performance would be, and how the improvement effects will relate with cost of developing the new energies as a result introducing the new energies into the society. This fiscal year will analyze the importance of the evaluation factors themselves that make it possible to analyze such a dynamic change as oil crisis, and evaluate effects caused by fluctuation in crude oil price, effects on energy consumption and environment, and the energy mix.

The studies have the objective of searching and evaluating biomass as energy resources and in this report, the current situation and the issues concerning development of cultivation of jojoba which has been an unused oily plant growing in arid and semi-arid areas in the southwestern USA. Its summary is as follows: (1) Jojoba is cultivated experimentally over about 20,000ha in the tropical and semitropical arid and semiarid regions at the almost same latitudes of the areas where it grows wild, (2) With regard to the areas qualified for development in the Chaco region of the western Paraguay, the La Rioja Province in the northwestern Argentina and the Eastern Province in the eastern Kenya, ample production can be expected judging from their natural environmental conditions and the growing characteristics of jojoba. (3) Jojoba is a dioecious plant and it takes 4-5 years from seeding to flowering. During this period, its sex difference cannot be identified, but a conclusion was obtained that the sex difference might possibly be identified by the isozyme method at its stage of young seedlings. (4) When cultivation techniques are firmly established and its price goes down to about 2 dollars/kg, jojoba becomes promising as substitute for sperm whale oil. 20 refs., 8 figs., 18 tabs.

In this study, the stability of annular leakage-flow-induced vibrations was investigated theoretically and experimentally for a translationally and rotationally coupled two-degree-of-freedom system. The critical flow rate was both theoretically and experimentally obtained as a function of the passage increment ratio and the eccentricity of the passage. A good agreement between the theoretical and experimental results was obtained. It was discovered both theoretically and from the experiments that instability will occur in the case of a divergent passage: the eccentricity of the passage lowers the stability of the systems.

Improvement of an antibacterial activity is one of the issues in modification of artificial teeth for an aged society. Study was made on improvement technique of an antibacterial activity with Ag ion as secondary corrosion measures. Partial gaps of dental materials themselves and gaps between materials and peripheral tissues causes bad breath or bad teeth through propagation of disease germs. Ag ion is harmless and has an antibacterial activity for bio-tissues from a macro-viewpoint, however, only corrosion germ causing bad teeth in mouths should be sterilized by controlling an elution rate of Ag properly. The antibacterial activity was controlled by controlling Ag ion implantation depth and rate, and Ag elution rate for dental materials. Experiment was made on an IMZ twinplus specimen implanted with Ag ion and an Ag thin film-coated specimen using beagle dog in comparison with an unmodified specimen. As a result, the very favorable antibacterial activity was obtained. Ag ion is effective for prevention of endogenous infectious disease due to mouth germs in dental surgery. 3 refs., 47 figs., 10 tabs.

It is recently, that is, in and after the 1980s that socio-scientific approaches began to be made to studies on `risk`. It started to be made clear that the progress of the scientific technology does not necessarily bring about good news to man, and obvious estrangement has begun to appear between scientific evaluation and social evaluation of risk. The subject of risk communication (RC) study is to tackle a proposition whether the estrangement will continue to exist as estrangement or the estrangement can be made smaller by any means. This paper explains the recent trend of the study. For example, as for how each individual thinks about risk, that is, the risk perception, a new framework is trially being constructed by introduction of the quantitative method using psychometrics. A duty of RC is to serve to bridge the gap between scientific technology and society which are controlled by values which are incompatible with each other. Therefore, RC will be more and more important. 15 refs., 1 fig., 2 tabs.

Safety technology is necessary and indispensable for future materialization of a hydrogen energy system. The survey was made from a viewpoint of safety technology in refining hydrogen at low temperature and in storing it in a low temperature liquid state. Japan has so far had no experiences for the handling and consumption of liquid hydrogen except the partial use at laboratory. Accordingly, collected here was literature on the storage, transportation, handling, low temperature refining of the liquid, etc. The present state of technology in Japan and abroad was grasped and items in the safety relation were picked up. As to the existing literature on the hydrogen relation, there is much literature on the U.S. NASA project, and there is also much on practical business details such as the handling of a large quantity of liquid. Therefore, from each literature mostly on the above, the literature on the liquid storage, transportation use storage tank and refining method was reviewed and arranged, and at the same time, the items were picked up of the safe disposal method, disaster prevention relation, and measuring relation. The paper also arranged the results of surveying hydrogen physical properties and equipment materials which are closely related to safety general, in particular, and examples of disaster. (NEDO)

Thermal efficiency enhancing system technology for existing thermal power plants is studied jointly with Indonesia to achieve energy conservation and power generation cost reduction and serve for suppressing CO2 emission. Site investigations were carried out for the study on enhancing thermal efficiency in component devices, including improvements in a device to rinse small pipes in condensers and in materials used in air preheaters, as well as for heat management and efficient operation of the plants. Indonesian engineers were received to develop device designing and thermal efficiency controlling programs, and for technical guidance. Site seminars were held to proliferate the achievements. Under the trend of increasing electric power demand, Indonesia is apt to place first priority on stabilized operation of power plants, with the efforts of thermal efficiency management staying behind partly due to fossil fuel price being low. The present project has made it possible to utilize hereafter the result of the rough design on improving the thermal efficiency in existing thermal power plants as has been done under the present project. Receiving the researchers and holding the site seminars also helped transfer the technologies on the thermal efficiency improving processes, and device maintenance and management methods. The project has also contributed to the consciousness reformation. (NEDO)

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)

A theoretical model was developed to study the mechanism of free surface sloshing in a vessel induced by a steady vertical jet flow. In the model, jet deflection is calculated with eigen values of the generalized Orr-Sommerfeld equation which is applicable to slightly non-parallel jet. Instability criteria employed in the model are (1) resonace condition between sloshing and jet frequencies and (2) {pi} phase relation between jet displacement at an inlet and global jet deflection. Numerical results of the mathematical model have shown good agreement with experimental ones, which justifies that the inherent instability of free jet itself and edge tone feedback are the main causes of the self-excited sloshing. 9 refs., 10 figs.

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

Discussions were given on mass cultivation in a water tank using sea water of an alga Ulvales used as feed for sea urchins and abalone. A fertilizer composed of ammonium sulfate and superphosphate of lime was used, and a water temperature was set as the environmental condition. Two kinds of Ulvales produced in different areas were used. One of the two kinds had full growth periodical and weight increasing rate low, but the other Ulvales had high weight increasing rate and no blights in alga bodies, and was found suitable for mass production. The result of a test on stocks of the latter species may be described as follows: multiple regression formulas for harvest, water temperature and illumination intensity were introduced for each cultivating condition for four cases regarding accommodation density and harvest frequency; and if a cultivating condition by which the harvest is maximized is adopted, a one cubic meter water tank placed on a place with good sunlight may be expected of producing as much harvest as 2181 grams at water temperature of 15{degree}C and 4899 grams at 25{degree}C. The cultivation requires the following precautions: aeration is required; sea water should be introduced into the tank; a mixed fertilizer with ratio of ammonium sulfate at 100 to superphosphate of lime at 15 may be used; water temperatures suitable for mass cultivation are 13 to 15{degree}C or higher; and light must be irradiated evenly. 14 refs., 9 figs., 5 tabs.

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

A polygonal mirror in a printer and the main shaft of a high-speed milling machine are used as models for the development of technology for applying C/C (carbon/carbon) composite materials to machine components that are required to turn at high speeds. Various C/C composites are tested for flexural strength and thermal expansion for the designing and manufacturing of C/C composites for the polygonal mirror and main shaft. The first coating on the C/C composite is deposited by laser/plasma hybrid spraying, and is a Mo coating. A spraying robot is experimentally built for homogeneous coating. In the case of polygonal mirror, an Al coating is deposited further by the gas-deposition method. The polygonal mirror proves excellent in both dimension and reflectance, and attains the target speed of 45,000rpm. In the case of milling machine main shaft, however, it is not strong enough to withstand 40,000rpm although it is a success from a viewpoint of coating technology and manufacturing technology. 15 refs., 33 figs., 13 tabs.

As lean burn of compressed natural gas (CNG) is applied to conventional gasoline engines, a combustion period largely increases, resulting in large combustion fluctuation and low thermal efficiency. Heterogeneous spacial air/fuel ratios also have an effect on combustion in lean burn area. By preparing a pre-chamber for a combustion chamber of high- compression ratio CNG pre-mixing SI engines to utilize premixture turbulence, rapid flame propagation is obtained in lean burn area, resulting high combustion performance. Furthermore, study was made on improvement of combustion performance in lean burn area under various compression ratios, intake pressures, pre-chamber shapes and EGR ratios. As a result, lean burn operation at high intake pressure by supercharging showed possible improvement of a thermal efficiency and expansion of inflammable limits. Higher thermal efficiency in lean burn area was also obtained by using higher compression ratios considering heat loss. Although EGR was effective in controlling NOx formed in lean burn area, strict control of both air excess rate and EGR rate was required to prevent lower thermal efficiency. 2 refs., 8 figs., 1 tab.

For the purpose of reducing aerodynamic noise of a high-speed elevator, the flow around the elevator car was subjected to a flow visualization experiment and numerical simulation using a model simulating an elevator. The state of the flow in front of the door was observed by visualizing the field of flow around the model submerged in a water bath using a poster color tracer. Further, a wind tunnel experiment was carried out to observe the effects of flow at the side wall of the car. An oily agent using TiO2 as pigment was used for observing the pattern of oil film on the surface of the model and the observed results were recorded on a video tape. Since the oil solution is white, the place where the oil film is peeled by a strong shearing force exhibits a pattern of black color which is the color of the model substrate. Flow in front of the door is different depending on whether the car is in the upward motion or in the downward motion and affected by the presence of apron. During the downward motion of the car, the vertical vortices accompanying the flow detouring from the rear surface to the front surface of the apron are generated at both ends of the apron and thereby the streamlines are concentrated to generate accelerated flow in front of the door. Suppression of vertical voltices is important for reducing noise during downward motion. Peeled flow and vortex interference appear at the side and back of the car and forms a field of complex flow. 12 refs., 10 figs.

This study analyzed the case of the flood disaster in the Northern Hyogo Prefecture in Japan caused by the Typhoon No. 19 in 1990, as to the residents {prime} behavior against the flood disaster, actualities of the living in the evacuation areas, and actions taken by the governmental offices, and brought the future problems in disaster treatment into light. The governmental evacuation recommendation has a certain effect on promoting the early evacuation of residents. An evacuation, whether done early enough or belated, depends on the reliability to the public information source and the face-to-face information transmittability. A trend shows that people living on the second floor get delayed in evacuation. The evacuation rate reduces in people owning houses, people engaged in farming, male sex, and large families. A trend shows that the rate of appealing living difficulties is relatively higher among people who evacuated to public evacuation areas including public halls than from those who evacuated to private evacuating places including houses of acquaintances. The administrative public organizations must maintain the disaster preventive administration wireless system and establish human information transmission network so that people can get information easily. Public evacuation places are required to have TV sets installed and information reporters arranged. 4 refs., 12 figs., 2 tabs.
