    Radiocarbon dating using accelerator mass spectrometry (AMS) was performed on numerous wood trunks from pumiceous deposits along the Nagata, Isso and Miyanoura rivers on the northern side of Yakushima Island, 60 km south of Kyushu Island. The obtained {sup 14}C dates were around 6.5 ka BP, which, in combination with the geological characteristics of the pumiceous deposits indicates that these specimens were buried during the Kikai-Akahoya (K-Ah) eruption from the Kikai caldera. However, the fact that they are not charred suggests that the origin of these deposits are not pyroclastic flows. Fourteen taxa (Pinus subgen. Diploxylon, Tsuga, Cryptomeria, Chamaecyparis, Myrica, Castanea, Castanopsis, Quercus subgen. Cyclobalanopsis, Trochodendron, Phellodendron, Lagerstroemia, Rhododendron, Myrsine and Symplocos) were identified through anatomical characteristics. This is the first discovery of forest species on the Yakushima Island before the devastating eruption.

    If an organism is regarded as a macromolecular system, the element device to construct the same is the molecular structure of nano meter scale formed by the functional protein existing in biomembranes. A lot of essential functions of organism such as the sense reception including vision, gustation, etc., photosynthesis, energy-substance production and so on are performed therein. In this paper, the structure, preparing process and the functions of the microchemical device using micro-bilipid membranes are described. The simulation of the sense receiving functions of organisms is tried by said microchemical device wherein, same as biomembranes, the base is bilayer lipid molecular membrane and the receptive protein for receiving signals from exterior and output molecules such as ion channels connected to said receptive protein and the like are incorporated in the membranes. Recently, it becomes possible to make a partial imaging of the bilayer lipid membranes fixed on porous membrane by the observation with scanning Maxwell-stress microscope. 4 refs., 3 figs.

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

    Since technology prefixed with 'super' is ultra-technology in another word, two kinds of work are introduced, that are on-going in the ultra-technology section in Mechanical Engineering Lab., the Ministry of International Trade and Industry. It is noted therewith that in order to realize 'super', introduction of knowledge of unfamiliar fields to mechanical engineering is one of ways. The first is a research on ion-injection onto solid surfaces by introducing quantum mechanics to mechanical engineering. Possibility of rotating new materials and physical properties is under investigation using MeV ion injection equipment. The second is a research on named 'cozy machine'. This is an example of introduction of physiological knowledge and is based on the concept that an operator can handle his machine pleasantly if it is controlled with his proper biorhythm. The possibility to form 1/f sway related to being cozy is shown using electrocardiographic signals upon which the interval of an R wave showing the largest amplitude is determined. Rotating machines are controlled in proportion to the potential. 13 refs., 3 figs.

    This paper introduces mechatronization of rotating machines in a plant, with application examples of electronic governors as the main subject. For centrifugal compressors, design and fabrication of anti surging control system have become possible by using a programmable logic controller (PLC) and a distributed control system (DCS) with fine scanning time. An electronic governor for turbine control has been added with a function to control amount of power generated by a motive force recovery device in a flowing catalytic cracking equipment by means of an expander inlet valve. This has made possible to operate the motive force recovery device automatically even under a low load operation. With an electronic governor to control supply and receipt amount of steam to and from an existing plant, the governor valve opening angles were so controlled that actual steam header pressure matches the setting, whereas the steam has become possible to be utilized without waste under normal operation. Operation of a comprehensive compressor/turbine monitoring system on DCS, operation of centrifugal compressors of two casings by using electromagnetic bearings, and motor speed control with use of an inverter heve also become possible. 8 figs., 2 tabs.

    At first, flagellar motors of bacteria are reviewed as a typical example of molecular machines in living cells. A rotational motor is embedded in the cell membrane at the root of the flagellum. The driving power of the rotation is the flow of hydrogen ion from the inside to the outside of the cell. In a normal state of a bacterium, potential difference of about 0.2 V is produced by the ion pump existing in the cell membrane. A molecular motor of sliding motion of muscle attracts the attention on the relation of the input and output of the molecular motor. The mechanism of the smooth motion without fluctuation in the fluctuated environment and the fluctuated input is unknown. Next, the motion of Paramecium is discussed as an example of a system composed of a number of molecular machines. Paramecium moves to a place of a suitable temperature when placed in a water tank with temperature gradient, however, it does not stop the motion at the place of the suitable temperature and increases a probability to change the direction when leaving, that is it takes a method of indirect probabilistic control. 12 refs., 8 figs.

    This paper describes the chaotic oscillations which are irregular unsteady oscillations of structures generated in mechanical engineering. The chaotic oscillations are apt to generate when the kinetic system contains both the stable balance and unstable balance in it at the same time. When an external force acts on the thin-walled structure of vehicle with a large portable volume, the chaotic oscillation response is generated with a dynamic snap through phenomenon. As a result of the numerical analysis using a simple model, the chaotic oscillation has non-linear characteristics. When a load is applied to the system, the snap through buckling occurs. For verifying the chaotic characteristics, are usually used the frequency distribution in which the chaotic oscillation response is analyzed using Fourier series expansion, Poincare map in which a series of points of displacement and velocity of the phase curve synchronized with the cycle of exciting force are extracted and mapped on a phase plane, or Lyapunov exponent which is a rate of continuous change in the distance between two points on the phase curve. The maximum Lyapunov exponent is calculated from the rate of change in the distance between the basic phase curve and the near-by phase curve. Thus, the chaotic oscillation can be determined. 31 refs., 7 figs.

    The characteristics of pressure wave propagation in a vacuum tube have been investigated experimentally from the viewpoint of vacuum protection in the beam lines of a synchrotrons radiation facility. Baffle plates having a single orifice of 5, 10 or 15 mm in diameter were installed in shock tubes 5 m in length, and 36.6 or 68.8 mm in diameter, in order to show the pressure wave or shock wave propagation as a model for the beam line. To evaluate the decay of pressure waves pressure changes with time at several locations along the side wall as well as at the end wall of the tube were measured. The results show that the effect of the orifices on pressure wave propagation and its decay is significant. The present investigation may contribute to the design and construction of high energy synchrotrons radiation facilities with long beam lines. 11 refs., 9 figs., 2 tabs.

    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.

    In the 21st century, reduction of environmental loads and creation of industries harmonizing with every city and region in the world are essential issues toward a sustainable society. Rapid conversion of a mass production/disposal society of resources and energy to a recycle-oriented comfortable city structure harmonizing with human being and nature is important. This paper clarifies the meaning of construction of a circulating/harmonizing society as condition of sustainable circulating urban structure, and points out the limitation of recycling technology from the viewpoint of entropy. The following themes are discussed for the role of technology for promoting circulating systems: an ecologically-sound-society under global environmental crisis, a sustainable city harmonizing with ecosystem, basic systems for the formation of an energy/resource recycling-oriented community, optimum operation of energy systems in recycle- oriented cities, an urban energy network and innovative element technology, and development of an urban simulator toward a self-sustainable and low-emission urban system. 5 refs., 13 figs., 1 tab.

    Space structure engineering comes under the combination of different engineering fields. Role of numerical analysis and simulation is large in space structure engineering. Considering space structure engineering as an application of non-linear mechanical simulation, constrains with simulation technology and analysis examples are explained in this paper. Following important points are confirmed by simulating the motion of membrane under external force acting on inner and outer surfaces at a particular point of square satellite model which rotates in tension membrane. When the external force is removed, each material point and membrane centre move with vibration, however centre of gravity of satellite moves very rapidly along the vertical direction of membrane centre. Further external disturbance (which develops on material points) propagates at all material points and membrane centre as a twisted wave. Maximum relative displacement between inner surface and outer surface decreases with the increment of initial angular velocity but not on the points of upper membrane. Fluctuation of position motion of satellite resulted from external disturbance is become small as initial rotation angular velocity increases. 10 refs., 6 figs., 2 tabs.

    Curricular guidelines are that importance be attached in the educating policy to the primary subjects of study and that compulsory subjects are to be acquired through practice. Out of primary subjects, those which should better be learned by all the students are set as compulsory subjects. Related subjects are divided into fluid-related subjects and control-related subjects. Experiments are conducted of the 'inspection of orifice flowmeter and Bourdon tube pressure gage,' 'fluid friction in round tube,' and 'servo-mechanism.' In a lesson on drafting, hydraulic equipment provided by business corporations is used. It is hoped that educating units be provided. Subjects of research for graduation and master's theses are the turbine-driven pump, constant pressure source system, hydraulic drive system, application of control theory to an injection molding machine, highly intelligent fluid, noise reduction for an automotive compressor, state of fluid in a hydraulic control valve, analysis of flow in pneumatic equipment elements, and cavitation in a vane pump. More than half of these subjects are pursued in collaboration with industrial or Government circles. It is expected that the Society will be an organization to benefit the students. (NEDO)

    It is necessary to recognize inertial properties accurately for modeling during machine development and design. A pendulum method is generally available as the conventional technique that recognizes the inertial properties. This method is difficult to be applied to an intricately shaped matter or heavy matter. Therefore, a characteristic matrix identification method that is very excellent in principle has been proposed, and many studies have been made for practical use. However, the influence that the measurement error of a transfer function used for identification exerts is open to investigation. This paper examined the technique that obtains the inertial characteristics of an elastic-supported mechanical structure using the characteristic matrix identification method. The influence that the measurement point position of the transfer function exerts on an identification error was also investigated. The result showed that the measurement point should be away from the node of the rotation mode as far as possible. This technique was applied to the engine system of a motorcar, and the identification result in a practical level was obtained using a transfer function gotten from the excitation experiment by a hammer. 6 refs., 8 figs., 1 tab.

    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.

    This report describes new control strategies of a self -commutated converter applied to the HVDC systems; that is, the cooperative control for a two-terminal transmission system and the terminal control which is applicable to a multi-terminal system. The DC voltage control with an upper and lower power-limiter showed excellent characteristics when applied to the two- terminal transmission system. A voltage margin method was also introduced as a power flow reversal method. These terminal control methods, if required, are able to change interchange power at the receiving end in the case of fault in the communication system. Moreover, the DC voltage control with two-stage voltage control characteristics was proposed for the multi-terminal HVDC system. with this mehtod, the DC transmission system can be operated continuously and stably cooperating electric power at each terminal even when one terminal is collapsed. The terminal control performance in the above two-terminal HVDC system was tested with a simulator. The result showed favorable performance characteristics at the time of power flow reversal and one terminal start-up during other terminal operation. 5 refs., 16 figs.

    There are two different ways of understanding the stress effects on martensitic transformation. To find out which one is more reasonable, examinations were given on the Stress- induced [mu][yields][alpha] martensitic transformation of iron particulates in monocrystalline copper matrix. The result revealed that out of 24 kinds of Kurdjumov-Sachs variants, the preferentially formed variants are various depending on the direction ([001][sub f] and [419][sub f]) and the sense (tension and compression). In addition, the easiness of generating a martensitic transformation depends upon the sense of external stresses. For example, when compared at the same plasticity shear distortion, the compression induced more martensite than tension at a stress of [001][sub f], but no significant difference was observed between the tension and the compression at a stress of [419][sub f], Further, in an experiment using polycrystalline copper-iron alloy specimens, the tensile stress had a greater effect on martensitic transformation than the compressive stress. 24 refs., 4 figs., 4 tabs.

    By the duplex effect produced by two kinds of phases of austenite and martensite, the transformation-induced plasticity (TRIP) steel is improved in ductility and fracture toughness. The strain-induced martensitic phase transformation could be associated with the strain localization behavior. Accordingly, the measurement of the amount of local transformation is necessary in order to construct a more physical evolution model in the constitutive equation. In this study, a new measurement system using a micro-hardness tester is proposed to obtain a volume fraction map of the martensitic phase expanding in the neighbor of strain localization. Then the system is applied to investigate the inhomogenous transformation behavior around the notch root of SUS 304 stainless steel bar under uniaxial tension. 27 refs., 11 figs., 1 tab.

    We have developed a systematic design task planning method based on a design structure matrix(DSM) and a lumped model- based framework for knowledge sharing in a concurrent design environment as key techniques for developing higher quality products in a shorter design time. The DSM facilitates systematic analysis of dependencies among design tasks and optimization of the design process. The framework based on a lumped model description of mechanical systems enables concurrent and cooperative work among multidisciplinary designers at an early stage of the design process. In this paper, we also discuss the relationships between these techniques and the product development flow from product definition to detailed design. (author)

    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.

    This paper describes the effects of coordination between the photovoltaic power generation and heat storage type air conditioning. In this study, a linear programming model was analyzed in four cases of spread rates of photovoltaic power generation and heat storage tanks by selecting four setting angles of photovoltaic cell panels and six models of irregular variation, to determine the optimum demand and supply. As a result of the simulation, coordination effects were found independent of the cases. It was verified that the coordination effects can be obtained independent of the cases. For the capacity of heat storage tank, the influence of irregular variation of photovoltaic power generation was equivalent to about 10% of the capacity. The difference in the power generation costs between in the daytime and at night, and the construction costs of heat storage tank and air conditioner were considered as factors determining the capacity of heat storage tank. For the setting angle of photovoltaic cell panels, it was found that the intermediate setting was effective between the setting focusing on the peak power and the setting maximizing the annual power output. 4 refs., 7 figs., 3 tabs.

    JIMIS-6 was held for 4 days between the 17th and the 20th of June in 1991. The registered participants were 258 representing 16 countries, and 160 papers were presented. 7 sessions were held in parallel in the symposium. The sessions were grouped into: fundamental properties; alloy design; thermodynamics, phase stability; mechanical properties; environmental effects; microstructure; and processing. The total numbers of reports by country for each session were introduced. The summary of each session was collectively introduced. Among the interesting subjects were silicide, although little in the number of reports, and gradually increasing study on composite materials with matrixed intermetallic compounds.

    Bearing reliability and safety of automatic systems in mind, man-machine roll allocation in the operation of facilities is examined, and the optimal roll allocation is proposed. The outline of the method for man-machine roll allocation is given in process instrumentation system, robotized assembly plant, railroad operation control system, and passenger airplane operation control system. The types of man-machine roll allocation in automatic system is divided into normal and emergency cases. Improvement in the total reliability of man-machine system can be expected by man-machine mutual complementary roll allocation. The core of the intelligent support system for emergency is the growing knowledge base, and the system performs intelligent support automatically or with the support of human in an emergency. For smooth man-machine information interchange at man`s own will, logical difference between man and machine must be adjusted in the man-machine interface. 8 refs., 2 tabs.

    The above-named department was established in 1996. It advocates, standing on the basis of mechanical engineering, 'adaptation with man,' 'symbiosis with society,' and 'harmony with nature,' and, under these mottos, aims to bring up engineers who are able to create technologies in the field of mechanical engineering. There is no independent subject for fluid power. Relative subjects are the science of flows, thermodynamics and exercise, energy and environmental engineering, and nature and flow. Lectures are given using textbooks mainly. There is no subject that requires experiment on fluid power. It is hoped that teaching materials will be provided. Studies for graduation and master's theses are the 'suction performance of toroidal pumps' and the 'fluid force in, and flow coefficients of, spool valves.' Collaborative researches with industrial circles conducted so far involve the 'study of automotive vane pumps' and the 'suction performance of toroidal pumps.' It is difficult for subjects related to hydraulics and pneumatics to interest students greatly. To interest and attract students, it is felt, the concept like 'hydraulics and pneumatics signify power sources' which gives a tough and mighty impression should be replaced by a softer-tone expression like 'hydraulics/pneumatics and mechatronics and control.'

    As one of the short circuits protection techniques in a power circuit, there is a technique called the current-limiting breaking. When a short circuit current commences to flow after a short circuit occurs, this technique limits and breaks this current under a certain value by some measures before this current reaches to the crest value. There is a current-limiting fuse in the best known one as a functional element doing the current-limiting breaking. However in case of a current-limiting fuse, when an element is fused off, because a current can not be flowed, it has to be replaced. As a new element to eliminate this defect and moreover with a current-limiting function, a self-rehealing type current-limiting element possessing the alkaline metal, Na as an element has been developed. In this report, as for this element called Na current-limiting element, together with elucidating a rehealing process after the current-limiting action experimentally in detail, an overcurrent coordination is investigated when this element is applied to a main circuit of the control center, which is one of the low voltage distribution systems. 5 refs., 8 figs., 1 tab.

    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.

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

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

    In the study of modeling and control of continuous DTB crystallizers, it has been common practice to assume complete dissolution of fine crystals in an external heater (fines dissolver). However, complete dissolution of fine crystals is not always guaranteed because the dissolution rate is finite. In this work, a model of an external heater is developed by taking account of the finite dissolution rate of the crystals. The model is used to study the influence of incomplete dissolution of fine crystals on the stabilizing control of the crystal size distribution (CSD). It is found to be difficult to suppress the sustained oscillation of CSD by using the conventional SISO controllers, which regulate the amount of fines crystals by manipulating the fines flow rate. This is because when the fines flow rate is very large, an increase in the fines flow rate can reduce the amount of crystal dissolution in the external heater. It is demonstrated that instability can be avoided by imposing an upper limit on the fines flow rate. Furthermore, it is shown that the upper limit can be predicted by using the results of open-loop simulation. (author)

    In order to investigate growth of Microcystis aeruginose, a representative toxic blue algae, and dynamics involved in microcystin degradation, the samples collected in Korean fresh water were cultured. Microcystin is an intracellar toxin, and is retained in a cell as long as it is alive. It is eluted out into surrounding water, when the cell which retains it is dead, and cannot be removed by a general purification treatment. It is therefore essential to remove the algae, when it is abnormally grown, to grasp the dynamics involved in transfer of the toxin resulting from cell breakdown, and to develop the adequate treatment method, to secure safe water. A. hemprichi and M. guttula as a protozoan show high ability of predating the M. aeruginose. Of the systems grazed with microanimals, those with A. hemprichi, P. erythrophthalma and M. guttula show higher degradation ability than the others. It is also found that microcystin is eluted out into surrounding water, when M. aeruginose is abnormally grown in a natural water area and self-degraded, and possibly persists for extended periods. 17 refs., 7 figs., 2 tabs.

    In detergent engineering and polymer processing, it is important to study the force exerted on an obstacle placed near a wall. In the present study, we numerically analyze the flow of viscoelastic fluids past a minute cylinder which is set at or near an inside wall of a two-dimensional channel. The upper convected Maxwell model and the finite-element method are used as the constitutive equation and the numerical method, respectively. Drag and lift of the cylinder are calculated for low Reynolds numbers (Re) and various Weissenberg numbers (Wi) of positive and negative values. Drag coefficient (C{sub D}) slightly changes with Wi. Lift coefficient (C{sub L}) monotonously decreases with increasing Wi irrespective of the sign of Wi. C{sub L} is greatly changed with Wi and is more sensitive to the elasticity of the fluid than C{sub D}. C{sub D} and C{sub L} decrease as the cylinder is separated from the wall. 11 refs., 12 figs.

    A highly safe and reliable robot is being developed capable of cooperating with human beings and executing complicated operations in a human working/living space. This paper describes the fiscal 2000 results. Development of robot motion library was continued for extended task for providing services to people in care houses for the aged controlling motions of the humanoid robot. A basic design for a personal service system by the humanoid robot was conducted with the aim of nursing assistance and for the objective of developing a portable terminal type tele-operation device. A public and a home cockpit were researched with the purpose of developing user interfaces for telexistence control. A dynamic simulator for humanoid robots was built, with motions of standing-up and walking examined, in order to develop basic theories for the dual-handed tasks aided by the leg-arm cooperative motion. To develop a robot that properly and safely cooperates and coexists with the human beings, it is essential to obtain a dynamically reasonable and natural control law, so that the basic studies were conducted in this direction. With the purpose of developing a motion capture and learning system, a virtual robot platform and an information acquiring interface were developed.

(1) On a thin film capillary method, 26 experiments of GaSb thin film crystal growth were conducted using the especially prepared high-accuracy electric furnace under microgravity. The wettability of thin film crystals was improved by refining equipment. Rhombus crystal planes and large crystal grains were observed in GaSb thin film crystals prepared under microgravity. (2) On a liquid phase method, the effect of the gravity on crystal structure and grain morphology was studied for synthesis of CdS fine grains. (3) On technological development of composite materials, the solidification experiment of Cu-In-Se melt was conducted under short time microgravity of 10{sup -4}g for 10 sec. As a result, more uniform texture and more high crystallinity were obtained under microgravity, and In in melt was concentrated by surface tension effect. It was suggested that high-quality CIS thin films will be obtained by Se doping into Cu-In composite films under microgravity environment.

    This paper describes survey on industrial technology heritages in Japan. In fiscal 1997, the previous data surveyed respectively were first collected, and mechanical engineering heritages up to 1945 were selected from these data. Since survey years and formats of these data are different, these data cannot be assessed with the same standard, however, these contents are useful for this survey. From the survey result on approach and technique of heritage survey and conservation in overseas countries, it was clarified that active surveys are being continued in the UK and USA. In fiscal 1997, the first year of this survey, emphasis was placed on confirmation of researchers` recognition on document survey, research method and assessment standard. Actual objects were surveyed on the basis of a restructured list of selected data to attempt explanation of the heritage database. The format and content of this database remain to be discussed in the future. To obtain the basic data for discerning future creative development of mechanical engineering, continuation of this survey is necessary

    In the light of the enlargement of demand/market of disaster prevention guard in association with changes in the social environment, development of a practical robot that automatically patrols and guards a building instead of a guard. The completed 'prototype guard robot' has a height of about 185cm and has a diameter of 65cm and moves by 4-wheel running at the maximum speed of 3km/h by the cooperative control for smoothly displacing/uniting the autonomous function and operational signals from remote operators. The robot recognizes the environment by various sensors (omniazimuth, laser, ultrasonic waves, light, infrared rays), patrols the inside of the building and lets the guard center (operator) know of it in case of emergency. The robot is also able to fight a fire by a fire extinguisher in the judgment of operator. As to the power supply, the robot can automatically change the consumed battery at battery exchange station and continue the automatical patrol and guard. Moreover, the autonomous function for going up/down in an elevator was developed by which the robot can move to different floors from the floor where he is using elevator. (NEDO)

    The loess is structural and unsaturated.Direct shear tests on intact loess and remold loess are firstly carried out by controlling the matric suction of unsaturated soil.Then the effect of the matric suction on the net stress strength index,parameter (φ)b in the Fredlund shear strength formula and parameter x in the Bishop effective stress formula of unsaturated soil is analyzed respectively.The experimental results show that net stress strength index increases with the increasing matric suction,(φ)b and x decreases with the increasing matric suction,and under the same matric suction,the net stress strength index,(φ)b and x of the intact loess are all larger than those of the remold loess.Besides,the unconfined compressive strengths of the intact loess,remold loess and saturated loess are measured by means of the single axial compression instrument.According to the definition of structural indices,the structural index of intact loess and remold loess with different water contents are obtained based on the unconfined compressive strength.Finally,the relationship among the net stress strength index and parameters (φ)b,x and structural index is also explored.The values of (φ)b and x unsaturated loess have the monotonic variation with the structural index.Under the same configuration conditions,the values of (φ)b and x of the intact loess are greater than those of the remolded loess,which reflects the differences in structural traits of the two types of unsaturated soil.%黄土既有非饱和性,又有结构性.首先在控制基质吸力的条件下进行了原状黄土与重塑黄土的非饱和直接剪切试验,分析了两种结构性状非饱和土的基质吸力对净应力强度指标、Fredlund抗剪强度公式中参数(φ)b、以及Bisho 抗剪强度公式中参数x的影响.表明两种土的黏聚力随基质吸力的增大而增大,(φ)b和X均随基质吸力的增大而减小;在相同基质吸力条件下,原状黄土的黏聚力、(Ψ)b和x均

    目的:通过对延期妊娠孕妇静脉滴注0.2%与0.5%两种浓度缩宫素,比较其促宫颈成熟及引产效果和超声下宫颈形态的变化.方法:对227例孕41~41+6周延期妊娠孕妇随机分成两组,各静脉滴注1种浓度缩宫素,比较两种浓度缩宫素促宫颈成熟及引产效果.结果:宫颈Bishop评分<7分者,两种浓度缩宫素提高宫颈评分差异无统计学意义(P>0.05),宫颈Bishop评分≥7分者,两种浓度缩宫素分娩率差异有统计学意义(P<0.05),并与超声监测下宫颈形态变化呈一致性.结论:低浓度缩宫素能产生有效宫缩,促宫颈成熟引产安全有效.宫颈Bishop评分<7分者,0.2%缩宫素发生胎儿窘迫率低,可作为促宫颈成熟引产首选;宫颈Bishop评分≥7分者,0.5%缩宫素促宫颈成熟引产催产效果好.%Objective: To compare the cervical ripening and induced labor effects and morphological changes of cervix under the ultrasonography between 0. 2% and 0. 5% of oxytocin for delayed pregnancy by intravenous drip. Methods: 227 cases of pregnancy of 41 ~41+6 week delayed first pregnancies were chosen and divided randomly into two groups, and the two groups were intravenous dripped by using two different concentrations of oxytocin. Cervical ripening and induced labor effects were compared. Results: For pregnancy with cervix Bishop scores under seven, the improving cervix bishop scores had no difference in two groups ( P > 0. 05 ), while for pregnancy with cervix Bishop scores equals and greater than seven, the rates of delivery was statistically significant (P <0. 05), which were conforming to the morphological changes of cervix under the ultrasonography. Conclusion: Low concentration of oxytocin is effective for uterine contraction and safe induced labor. The pregnancy with cervix Bishop scores under seven, 0. 2% oxytocin has lower possibility to canse fetal distress , which would be the first choice for cervical ripening and induced labor

    In this study, a sea-surface water Δ14C record of AD 1966-2000 (i.e., after the atmospheric nuclear-bomb testing period of the mid-1950s to early 1960s) was reconstructed from a coral sample collected from Iki Island, western Japan. The island is located in the Tsushima Strait where the Tsushima Current flows from the East China Sea (ECS) continental shelf into the Sea of Japan, indicating a strong influence of the ECS shelf water on the island. It is widely accepted that the Tsushima Current originates in the area between the ECS shelf break and the Nansei Islands further offshore as a branch of the Kuroshio Current, although another possible origin is the Taiwan-Tsushima Current System. The Δ14C record from Iki Island shows the following evidence of a response to the atmospheric nuclear testing: (1) an increase from ~55‰ in 1966 to ~133‰ in 1970, (2) a plateau ranging between ~123 and ~142‰ during the 1970s to the late 1980s, and (3) a gradual decrease from ~115‰ in 1990 to ~83‰ in 2000. Comparison of this record with coral Δ14C records from the Nansei Islands (Okinawa Island, Ishigaki Island and Kikai Island), located ~160-280 km off the ECS shelf break and little influenced by the shelf water, suggests that the surface-water Δ14C around Iki Island was ~30-45‰ lower than that of the Nansei Islands from the mid-1960s to late 1970s, and that the Δ14C difference between Iki Island and the Nansei Islands decreased from the end of the 1970s to ~0-15‰ in the mid-1980s to 2000. The lower Δ14C around Iki Island can be explained as follows: (1) in contrast to the Nansei Islands area, the ECS shelf area is a vertically mixed, highly concentrated carbon reservoir significantly connected to subsurface and deeper waters outside the shelf area, strongly suggesting that the surface-water Δ14C of the shelf area (perhaps excepting very shallow innermost shelf areas) was significantly less sensitive to the atmospheric nuclear-bomb 14C spike than that of the

    In the present study multi-approach has been employed to investigate the Holocene sedimentations of the river discharge and volcanic particles in the northern Okinawa Trough. During 11. 0~6. 0 kaBP,amounts of terrigenous particles and organic matter input to the northern Okinawa Trough as well as the particle grain sizes were found to have obviously decreased, which was a result from 50~60 m global sea level rise and a rapid retreat of coastline in the East China Sea. Thereby, the terrigenous input to the Okinawa Trough should be first orderly controlled by sea level changes in the early to middle Holocene. The volcanic glass shard concentration prominently increased during 8. 1~7. 8 kaBP, which was recognized as the K-Ah tephra derived from Kikai volcano in southern Japan. However, the K-Ah tephra age in the deep sea sediment sequence is much older than that of 7. 3 kaBP in a variety of terrigenous records. This inconsistence was probably induced by the uncertainty of marine ~(14)C age calibration. Reservoir age of the northern Okinawa Trough in the early Holocene was considered to be 300 ~ 500 years older than that of the present. A set of proxy records based on the distribution of terrigenous alkane show an increasing expansion of the C_4 plant in the East Asia continent during the Holocene, hinting the aridity was gradually enhanced in the inner part of China, which is consistent with the Holocene decrease in summer monsoon precipitation in this region.%运用多种方法,重建了全新世以来冲绳海槽北部地区陆源输入物以及火山碎屑物的沉积历史.在11.0~6.0 kaBP期间,北部冲绳海槽的陆源物质供应量主要受控于海平面变化.由于该时期海平面上涨了50~60 m,东海陆架上的海岸线快速后退,导致输入北部冲绳海槽的陆源碎屑物和有机质明显减少,沉积物粒度变细.在8.1~7.8 kaBP期间,沉积物中的火山玻璃数目显著增加,导致该时段沉积物粒度急剧增大.经对

    Evaluation of function-enriched edible oils: Preventive effect of lipid peroxidation; (a Heat exposure: Commercial rape-seed oil and extra virgin oil were used as controls. For preparation of the test samples (function fortified oils of tomato-juice waste-residue and grape wine- ferment waste-residues, it is described in above section (1. All oil preparations were exposed to high temperature at 150oC and peroxide value (POV, acid value and TBARS were measured at various times as described. The methods of measurements of POV, acid value and TBARS were adapted conventional standard method described elsewhere. (b Light exposure: Similar to (a they were exposed to excessive light using Nippon Ikaga Kikai (Tokyo, LH-200-RDS equipped with fluorescent light tube (x3, NEC FL40S-2XN, 3.2K lux at 390-730nm. Result and Discussions: (1 Extraction of carotenoids etc. Modern edible oil refining processes are highly elaborated and efficient. The most of the commercial edible oils in the market are so purified that many important antioxidant components are mostly removed during refining process. Oils became mostly colorless and odorless; and they lack are devoid of anti-oxidative or radical scavenging components. We measured anti-alkyl peroxy radical (ROO.-scavenging activity, and found that many commercial oils have very little such activity (Figure 1. Many disposal- of tomato juice or extraction waste-residues in wine making, yet contained significant amount of functionally useful components that may be recovered by immersing the dried waste residues in the functionally poor oil, ie., low grade oils. Figure 2A, B shows it was indeed possible to recover such component like lycopene and carotenoids, and the spectrum of this oil exhibits multiple peaks correspond tomato lycopene. (2 Antioxidation activity: (a Acid value after light and heat exposure. Commercial highly purified edible oils are vulnerable for oxidation and resulting in lipid or alkyl hydroperoxides formation (ROOH, which
