    It has been reported that hydroxyapatite (HA), which is the main inorganic component of teeth and bones of homo sapiens and used for biomaterials such as artificial tooth roots, adsorbs viruses such as influenza viruses. In this article, the history of development up to now of HA and its adsorption mechanism of protein, virus, etc., are introduced. HA was applied for chromatography in 1956 becoming one of the separating and refining methods of protein and nucleic acid, then after the development of spherical porous HA, it has become applied for high speed liquid chromatography (HPLC). Also by means of a column filled with HA granules, T-cells have been able to be purified in a short time from lymphocyte which was separated from the blood of homo sapiens. Recently it has also been reported that HA granules can adsorb influenza viruses, Japanese encephalitis viruses, polio viruses and hepatitis B viruses, and a cold-preventative mask based upon this report is now on sale. 11 refs., 7 figs.

    Recently, the two-degree-of-freedom (2DOF) control has been widely recognized to be efficient. The major merit of the 2DOF control is the independency between the tracking performance and the feedback performance. However, there is a limitation for the tracking performance in the 2DOF control system. In this paper, we propose new control system which consists of the conventional 2DOF controller and the learning controller. The role of the learning controller is to realize high tracking performance, which can not be realized only by the 2DOF controller. the learning controller can be designed only by using information of a specification for the 2DOF controller and it does not need information of the controlled plant. We show some experimental results to verify effectiveness of the proposed system. 9 refs., 18 figs., 1 tab.

    Softness is required for machines equipped to some extent with intelligence by virtue of advancement of computer science so that they live friendly, contact safely and communicate softly with human. The softness of machines is determined by impedance parameters such as inertia, viscosity, rigidity and so on. The technology to control these parameters positively is presumed to be an elemental technology to control machine softness. The present status of this technology is introduced by taking a field of robots as an example and developmental tasks of soft machines to live friendly with human is reviewed. A system of one degree of freedom is explained as a basic procedure to modulate impedance of machine systems, being extended to robot arms with plural joints. Next, a method for controlling arm rigidity of robots (direct compliance control) is explained, wherein actuators of each joint working in accordance with dislocation of apexes of Robot arms are conceived not as an apparatus to yield power, but as an independent apparatus to yield spring effects. 19 refs., 9 figs.

    Particularly noticeable items out of the suspension, steering system, braking system of automobiles announced in 1996 were outlined. No new particular system was adopted for the suspension, and the mainstream was improvement and reinforcement of the conventional methods. In the area of steering, expansion of the adoption of rack and pinion system and simplification of the power steering system were noted. In the area of the bracking system, anti-lock braking systems (ABS) were employed more as the standard equipment, and cost reduction and decrease in the size and weight were attempted. In the control system, a system of improving the turning performance of the car was employed which detects front and rear G, side G, car speed, steering angle, and yaw rate to control the distribution of driving force for the right and left wheels. Toyota adopted VSC (vehicle stability control) system for Crown and Mark 2 cars. GM installed ICCS to Cadillac. 16 figs., 1 tab.

    The automation of the steam plant has been advanced together with a progress of the computer technology, starting from the computer control in the States around 1960. The automation by the computer control in Japan has achieved the steady progress without experiencing the failures, because the experiences in the States have been made good use of, and in addition, the development has been made by adjusting with a progress of the computer technology. When following up the automation history by the computer control in the thermal (steam) power plant in Japan, a partial automation centering around the turbine main unit has been practically applied around 1970, and then making such experiences as a foothold the direct digital control (DDC) by the computer has been attemped to be expanded, and simultaneously the automation of the total domains including starting and stopping operation of the plant has been achieved around 1975. As the control was initially the analogue control time for the control technology, on the other hand, the digital control technology has made a great progress in the computer direct control.

    Various novel techniques for measuring cerebral functions or the functions of the cerebral cortex are described. The brain measuring equipment is divided into two categories, morphology measuring means and function measuring means. Measuring the morphology are computer tomography, magnetic resonance imaging, and measuring the functions are positron emission tomography, optical recorder, functional MRI, and magnetoencephalography. Since SQUID (superconducting quantum interface device) has of late made a rapid progress to facilitate multi-channel measurement, the measurement of the magnetism of living body has become feasible and its study has come to be conducted with vigor. In the measurement of cerebral magnetism, two types of measurements are carried out, which are the measurement of magnetism spontaneously generated without the application of any particular stimuli and the measurement of magnetism in which the mathematical average is studied of magnetic responses induced upon the repeated application of predetermined stimuli. The spontaneous magnetism measurement involves epilepsy, Fm{theta}, {alpha} waves, etc., while the measurement of induced magnetism covers audition, vision, taste, pain, etc. 12 refs., 8 figs., 1 tab.

    The research and development as well as adoption to actual vehicles of electronic control systems for such each section of a chassis system as suspension, steering, driving and braking, etc. have been expanded drastically in recent several years and its momentum is even more than predictions made before. Quite recently, integrated control systems are becoming the main stream of research and development which reduces demerits of each unit control system as far as possible, avoid the cases that a certain kind of performance is improved by one control measure, but other kind of performance becomes degraded on the contrary, and derive much more merits of each unit control system. In this article, the integrated chassis control systems now being studied and developed by Nissan, Toyota and Mitsubishi, etc. are briefly introduced and in addition, the integrated control system covering the active suspension {center dot} yaw rate feed back active 4WS (4 wheel suspension) {center dot} ABS (anti-lock brake) {center dot} TRC (traction control) is explained which was adopted for the Soarer of 1991 model. 16 refs., 16 figs.

    In order to study the optimal control of helicopters, the control procedures following power failure were theoretically investigated by applying nonlinear optimal control theory to the following four optimization problems. The first was minimization of the touchdown speed following power failure. Comparisons between the calculated optimal solutions and the empirical flight test results showed that pilots used nonoptimal controls, especially in the timing and amplitude of the collective flare before touchdowns. The second was prediction of the height-velocity (H-V) boundaries. The calculated H-V boundaries showed good correlation with the flight test results. The third was optimization of the takeoff procedures for category A STOL operation following power failure. The results showed that the required takeoff distance using the normal takeoff procedure can be significantly reduced. The fourth was evaluation of the takeoff performance for category A VTOL operation. The calculating method of the maximum takeoff weight was confirmed, and possibility of allowing the payload to be increased was shown. 38 refs., 53 figs.

    The berthing of a ship is a kind of control operations of position, speed and direction of a ship in order to bring a ship alongside a quay. Berthing control is accompanied with a hard problem in which the 6 freedoms of position and speed in 3 directions such as fore and behind, right and left and a revolution must be controlled. In this study, a concept of the agent was introduced as a means of berthing. The agent is a computer program which can be worked in a person`s place. If an autonomous intelligence is carried on each element such as a tugboat or a propeller of ship, the element is able to act based on judgement decided by itself without an instruction from a control center. Thereby, the berthing control system as a multi-agent system having an adaptability and a cooperativeness will be realized. Then the multi-agent system to help berthing was constructed by applying the Muller`s three phase model as a cooperative autonomous agent and by sharing the role of each phase. 8 refs., 12 figs., 1 tab.

    A flame controller is introduced, developed for an automated system for gas cutting and capable of automatic control of the preheating flame. This system comprises gas flow controls (MFCs), one for each torch, a control module that gives instruction to the MFCs, and a control panel that performs calculation. A cutting oxygen pressure control and introduced gas pressure sensor are also provided. An MFC senses the changes in the mass of gas flowing in its sensor section and, in compliance with the difference between what it senses and the instructed value, regulates the control valve for a flow proper to tune up the preheating flame. The control to which the preheating flame is subjected comprises three flame modes and preheating gas on/off timing. This controller is equipped with the teaching function that memorizes the preheating flame appropriately adjusted by a skillful operator, and is capable of accumulating and memorizing the flows measured by the MFCs. A cutting equipment provided with this controller is advantageous over other types in points of shortened preheating flame adjustment time, linkage with the time interval setting unit, and economical use of gas. 9 figs., 2 tabs.

    Study was made on the effect of exposure to diesel emissions on inflammatory cells in a rat lungs. Four kinds of exposure gases with different contents of NO2 and particulate were prepared by diluting diesel emissions. Rats were exposed to diluted diesel emissions for 24 months, and inflammatory cells were detected morphologically in light microscopic and TEM specimens. As a result, particle-laden- alveolar macrophages increased dose- and time-dependently into the submucosa of intrapulmonary bronchioles, alveolar spaces and interstitume of alveolar walls, and bronchoassociated lymphatic tissues. Mast cells infiltrated into the interspaces of epithelial cells in airways. In the submucosa of the terminal bronchioles and the interstitume of alveolar walls, some sorts of inflammatory cells such as mast cells, plasma cells, neutrophils and lymphocytes infiltrated, and some cells showed cell-to-cell contacts. However, the airways were rarely injured by infiltration of inflammatory cells except for a fibrotic change. 2 refs., 2 figs., 2 tabs.

    For mass propagation of strawberry seedlings via callus by liquid culture method with a higher cultural efficiency, it is required to form calluses which are dispersed homogeneously in liquid culture and are easy to isolate to individual. Then an investigation on the effect of plant hormones on callus formation was conducted. Sorts and concentrations of plant hormones, regeneration ratio from the callus, and the frequency of morphological mutations of the plantlets were examined. Auxins; 2,4-dichlorophenoxy acetic acid (2,4-D) and two others, and cytokinins; kinetin (KIN) and two others were used for plant hormones. These hormones were tested in serial concentrations between 0 to 5 ppm and in combinations with each auxins and cytokinins. Cytokinins were better to form and grow the callus in the vicinity of 0.2ppm, and auxins gave the highest growth rate of callus at 0.5 to 2 ppm. It was concluded that optimizing condition for the callus formation was KIN 0.1-0.5 ppm and 2,4-D 0.1-1ppm. 18 refs., 15 figs., 3 tabs.

    In order to eliminate the steady state tracking error, it is common to employ integral compensators in servo Systems for constant reference signals. The LQ optimization technique is extensively used for the stabilization, and the obtained feedback control system has been applied choose to an optimal servo system. However, if the dynamic response of an identical model is unequal to that of the real plant and there is disturbance to the plant, accurate control using the LQ optimization control method is difficult. In this paper, several robust control system designs for a reference model are introduced in the following and robust stability and transient behavior are considered. We propose such robust control systems based on an optimal control method that has a two-degree-of-freedom (2DOF) system. First design of the robust optimal servo system is by a 2DOF optimal control with disturbance observer. Second is designed by a 2DOF optimal control with H controller with consideration to the mixed sensitivity problem. The experiments are carried out under several conditions, and we discuss the difference of control performance by L{sub 2} norm. As a result, the 2DOF optimal control with disturbance observer has shown good control performance in the robust and stable positioning of the oil hydraulic cylinder. (author)

    We have analyzed theoretically the virtual slice-bolt corresponding optimizing control of basis weight profile in paper machines that was previously devised by the authors. It has the following features: (1) Optimizing control of basis weight profile in slice-bolt position generates a saw tooth profile between slice bolts, and does not satisfy quality demand in actual plants. (2) We have devised a virtual slice bolt corresponding profile that is obtained by averaging the basis weight raw profile not only on the position at each slice bolt but also on the intermediate point between the slice bolts. We have applied a virtual slice bolt corresponding optimizing control that minimizes the square sum of the profile errors and succeeded in satisfying the quality demand of actual plants sufficiently.

    Study regarding the establishment of transfer function model and control strategy for cement grinding process has been carried out so far. Particularly, as for control strategy, establishment of hierarchy control or necessity of adding cut size control also in assistant control were proposed. In this report, design of multivariable controller considering the dynamic characteristics of the systems proposed above was studied. In the design of this report, application of H{sub infinity} robust control considering the corresponding nonlinearity or variation was investigated. Further, design of two-degree of freedom for improving quick-responsibility, or corresponding non-coherence were studied side by side. As a result, it was understood that the establishment of multivariable control system is effective for improving quick-responsibility and to maintain set value for fine particles regarding the grindability of worsened raw material, and also, as for the design of the H{sub infinity} robust control, the corresponding variable was identified quantitatively using the established model. 11 refs., 10 figs., 1 tab.

    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.

    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.

    Described herein are dynamics and model experiments of the system in which positioning of a floating marine structure by mooring is combined with thruster-controlled positioning. Coefficients of dynamic forces acting on a floating structure model are determined experimentally and by the three-dimensional singularity distribution method, and the controller is designed by the PID, LQI and H{infinity} control theories. A model having a scale ratio of 1/100 was used for the experiments, where 2 thrusters were arranged in a diagonal line, one on the X-axis. It is found that the LQI and H{infinity} controllers of the thruster can control long-cycle rolling of the floating structure. They allow thruster control which is insensitive to wave cycle motion, and efficiently reduce positioning energy. The H{infinity} control regulates frequency characteristics of a closed loop more finely than the LQI control, and exhibits better controllability. 25 refs., 25 figs.

    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.

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

    A new control system with high response speed for self -commutated Static Var Compensator(SVC) has been developed. This system does not require phase detection, obtains real and imaginary components of instantaneous power from AC voltage and AC current of the system, and conducts vector control(VQ vector control) using these components. The operation process and the control principle in the VQ vector control system acre explained by block diagram. Then, responses of the system in each case of system start-up operation, sudden change of AC voltage magnitude, sudden phase change, and one phase line grounded fault were investigated by digital simulations of Electro-Magnetic Transients Program(EMTP). As a result, effectiveness of the control system by this system was verified. Sampling periods of input signals for digitalizing the control system were also examined by digital simulations and Bode diagram. Results of both methods agreed well with each other, and it was found that O.3ms or less is a suitable value. 6 refs., 12 figs.

    A biologically controlled polymer synthetic process is a process to control reactions by using such biological molecules as enzymes and genes to synthesize polymers. Since the process consists of synthetic reactions controlled by such biological molecules as enzymes and genes, the process is expected to exhibit various excellent characteristics such as reaction selectivity, structural orderness, and moderateness in the reacting conditions. However, the most important characteristic is its environmental harmony. The present investigation has viewed the current status of researches and the future research problems by positioning the biologically controlled polymer synthetic process as an environmentally harmonized process. The present investigation has focused its emphasis on the following three biologically controlled synthetic processes. The first is a gene controlled protein synthetic process; the second is an enzyme controlled polymer synthetic process; and the third is a biologically controlled inorganic and organic hybrids synthetic process. Particularly, the biologically controlled polymer synthetic process is a process to synthesize polymers by utilizing biologically controlled molecules in genes. 3 refs.

    In the control of ROVs with a position sensor (by means of under sea accoustics) and computer aided trajectory controlling function, it is only necessary to provide an information on the orbit to follow. In order for reducing the burden for the operators it will be frequently used in the future under-sea operations. Especially, in addition to such conventional operations as inspection and examination, materials transportation will be an important role. In this study, in order to apply an orbit trajectory control using a sliding mode to ROVs, a basic system was constructed which contained an ultrasonic location detecting system. Confirmation of basic actions of the orbit trajectory control control to follow a three-dimensional orbit. Maximum error to the preset orbit was within 5 m. It was found that the ROVs could hoist an object of 530 g mass (60 g in water) corresponding to 10% of the weight of the vehicle and transferred in a changed dynamic conditions. 10 refs., 18 figs., 3 tabs.

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

    Non-point pollution source is an impossibly specified pollution source running from city areas, agriculture land areas, natural land areas or the like, and particularly it is said to occupy 20 to 40 percent of the total amount of pollution load running into a closed water area such as lakes, sea areas or the like. Additionally, although the proportion of specific pollution is lowered due to the popularization of sewerage systems and the like, an increase of the proportion of non-point pollution sources is expected. In this paper, run-off models of pollution load in city areas used practically in Japan and abroad are introduced, and a tendency of a model, which will be requested in the future, for analyzing the pollution load of non-point pollution source is described. As a model in Japan, the model developed by the Public Works Research Institute of the ministry of Construction for predicting a runoff load amount from a water amount of a confluent type in a raining day is introduced. As models in foreign countries, Hydro Works in Britain, MOUSE in Denmark, and XP-SWMM in USA are introduced. 4 refs., 2 figs.

    The paper described the FY 1999 results of the experimental verification on a centralized load control system for the residential electric power demand. The air conditioning control is effective for load leveling, and for it, it is important to infiltrate the consciousness of energy saving into people. Users are not very interested in the information on power rates, would rather tend to seek comfortableness, and are less conscious of energy saving on days of unusual summer heat. Further, the power control in peal time zone was made by indicating users the actual state of power use by a combination of the two-way communication and the automatic meter reading system. However, at present, it cannot be denied that the power rate is higher even in indirect load control equipment with necessary/minimum conditions than the existing power source. It is a must to reduce the cost. The liberalization of electric power is progressing fast, and incentives for DSM are decreasing, but each of advanced countries is getting sensitive to the obedience to COP3. In addition to DSM such as the rebate program and financing program by the existing surcharge system, they are making efforts for development/promotion of new energy by creating the green electric power market. The load control technology is expected which does not disturb comfortableness and amenity of users. (NEDO)

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

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

    Co-Cr alloy, SUS 316L stainless steel, pure Ti and Ti-6Al-4V ELI have been used as implant materials. Ti-6Al-4V ELI has been most widely used as an implant material to date because of its excellent combination of biocompatibility, corrosion resistance and mechanical properties. Since toxicity of V etc., and high moduli of elasticity have been pointed out, {beta}-type biomedical titanium alloys are recently getting much attentions, New {beta}-type biomedical titanium alloys composed of non-toxic elements such as Nb, Ta, Mo, Zr and Sn with lower moduli of elasticity and greater strength were, therefore, designed using alloy design method based on the d-electron theory in this study. Tensile test, measurement of modulus of elasticity and evaluation of biocompatibility were conducted in order to investigate the mechanical properties and biocompatibility of the designed alloy. Tensile strength and elongation of Ti-29Nb-13Ta-4.6Zr are, in particular, equivalent to those of conventional biomedical titanium alloy such as Ti-6Al-4V ELI, and modulus of elasticity of Ti-29Nb-13Ta-4.6Zr is lower than that of Ti-6Al-4V ELI. The moduli of elasticity of the designed alloys are equivalent or lower comparing with those of conventional biomedical titanium alloys such as Ti-6Al-4V ELI and Ti-13Nb--13Zr. The biocomparibility of Ti-29Nb-13Ta-4.6Zr is equivalent to pure-Ti, and biocompatibility of Ti-29Nb-13Ta-4.6Zr is much greater than that of Ti-6Al-4V. The new {beta}-type titanium alloy, Ti-Nb-Ta-Zr, designed in this study is expected to have greater performance for implant materials. (author)

    A comprehensive evaluation/verification is conducted of the totality of the microlysis system of cell information that underwent research and development in the preceding fiscal year. The system is examined for its optical detection capabilities, involving scattered light detection and operationality in fluorescence detection and compensation. In the measurement using the forward scatter and side scatter, the system is found to be capable of cell analysis, clearly distinguishing single cells from aggregated cells, live cells from dead cells, and human lymphocytes from monocytes/granulocytes. As for separation, the system is found to be excellent in sorting beads onto the slide, sorting cells into the test tube, evaluation of the sorted cell surviving rate, and in the verification by acquisition of images of sorted cells. Performed for total system evaluation using clinical samples are the analysis of leukemia patients' lymphoid subsets, fluorescence compensation and separation for six colors, CV (coefficient of variation) evaluation and DNA (deoxyribonucleic acid) indexing using PI (propidium iodide) stained normal lymphocytes, and the analysis and separation of gynecologic tumor related samples.

    Efforts were made to develop a microanalysis system of cell information. In the development of element technologies, technologies of CGH (comparative genome hybridization) analysis and DNA (deoxyribonucleic acid) microarrays were studied, and it became feasible to detect information on intercellular molecule anomalies, probably to serve as cancer markers, at the chromosome level. In the research on the total system, a 2nd protocol apparatus was designed, built, and evaluated, and target goals involving size reduction and optical detection and isolation capabilities were achieved. In the evaluation of scattered light, the relationship between diameter size and forward scatter light intensity was confirmed using human peripheral blood lymphocytes and cultured cells, which enabled cell identification. In the measurement of the two parameters of forward scatter and side scatter, lymphocytes were clearly isolated from granulocytes/thrombocytes, which made feasible the independent analysis of peripheral blood lymphocytes. Thanks to the 2-parameter measurement, isolation of live cells from dead cells became available. (NEDO)

    This paper describes the digital control technology of pulse MAG welders for stable operation and performance improvement. Pulse welding forms a droplet at a wire tip during pulse period, and separates the droplet by pinching it by pulse electromagnetic pinch force. This technology automatically optimizes and stabilizes welding current waveform by digital control to obtain such smooth one pulse- one droplet transfer under various welding conditions, and also controls external characteristics of welding power sources to obtain a constant arc length regardless of the distance between the tip and matrix. The technology offers superior welding stability in a small current range below 100A, and superior high-speed weldability, arc startability and transient responsibility. The newly developed pulse MAG welder mounts the control function of penetration for the first time as pulse welder, and allows stable penetration regardless of torch height. In addition, the welder allows reduction of noise level, superior weldability of galvanized steel sheets, superior basic welding performance, and automatic setting of welding conditions. 2 refs., 19 figs.

    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 photovoltaic/wind/diesel generating system that uses a storage battery as auxiliary power has been proposed to supply power from the system to the independent area. In this system, it is important to generate no insufficient power from the viewpoint of effective energy utilization and minimize the fuel consumption of a diesel generator. Authors have proposed the adaptive fuzzy control that changes the shape of the membership function of input variables according to the parameter indicating the system state. However, a parameter was rapidly changed in the conventional method. This badly influences the control. Therefore, the way to determine the parameter that indicates the state of this system was improved. Assume that an input value is set to the average value between a certain point of time and the {Delta}t time as the method for determining a parameter. If the {Delta}t value is lower, the change in a membership function is more effective. As a result, a greater fuel reduction effect was obtained. 4 refs., 8 figs., 1 tab.

    Excitory impulses for motor systems are controlled by the psychophysiological nervous systems in the body either autonomically or voluntarily. Involved in the voluntary control loop are motor cortex, basal gangalia, thalamus, cerebellum, etc. The purpose of this study is to confirm whether it is possible to reduce or emphasize the muscle contraction voluntarily through electromyogram (EMG) feedback training. EMG can indicate the excitory impulses of motor units. In the experiments, electrodes were placed on the skin above muscles. A significant reduction effect was observed for subjects trained in relaxation of the forehead musculature through EMG feedback. Results of the experiments suggested that biofeedback training for relaxation of the forehead tensional muscle might be effective in eliminating muscle contraction, and that feedback training for activation of damaged muscles might be effective in emphasizing muscle contraction. 4 refs., 9 figs.

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

    `DELTA` developed for survey of the sea bottom over a wide are can be operated both as a towed and a self-propulsive vehicle. The shape is similar to a delta wing airplane and the vehicle has two propellers and weight shift apparatus as actuators. In the towing mode only the depth is controlled by the trim weight. In the self-propulsive mode the direction is controlled by the difference between the right and left thruster`s thrust and the depth is controlled by the pitch moment generated by the change of the thrust. The motion control is mainly done by the thrusters and the trim weight to maintain static balance. Field experiments were carried out to confirm the performance of the ROV, and some successful results are shown. The experiments suggested that speed control is essential to operate the ROV when the mother ship follows on the ROV. Tank tests on speed control were conducted and it was found that {+-}20% speed change from the nominal speed was possible. 4 refs., 22 figs.

    One of the most emphasized problems to be solved in power systems in recent years is the line-current harmonics problem. This is due to the use of diode rectifiers, PWM converters, nonlinear loads and so on. To reduce or eliminate such current harmonics an active power filter (APF), which is a sophisticated power electronic converter, has been studied and used in some practical applications. In this paper, we propose and discuss two new control methods for three-phase shunt APFs: the sinusoidal line-current control method and the instantaneous-reactive-power compensation control method. They are based on pulsewidth prediction control, or a predictive-instantaneous-current PWM control. Neither any instantaneous power information nor coordinate transformation is necessary for control. In the sinusoidal line-current control scheme,, the controller governs the switching devices of the APF by using the pulsewidth that is optimally predetermined at the beginning of every switching period with the sinusoidal current reference. The line-currents flow sinusoidally and are in phase with the voltage accordingly. In the instantaneous-reactive-power compensation control, the control is performed so that the resultant circuit of the load and the APF is regarded as a time-variant conductance circuit model. The APF with this control scheme can cancel effectively the instantaneous reactive component produced by the load though the controller is simple. This paper discusses the performance characteristics of the APFs when a three-phase diode rectifier and an unbalanced load are connected to the line. The practicability of the proposed methods is verified by experiment. 8 refs., 10 figs.

    The purpose is to develop technologies on efficient generation and control of femtosecond optical pulses using a novel semiconductor optical devices. We studied a modelocked Cr:forsterite laser pumped by a diode pumped Nd:YVO4 laser. Both Kerr lens mode locking and semi-conductor saturable absorber initiated mode locking have been achieved. The minimum pulse width for pure Kerr lens mode locking is 26.4 fs, while for the semiconductor saturable absorber initiated mode locking, the pulse width is 36 fs. The latter is very resistant to the environment perturbations. We also present the measured dispersion data for the forsterite crystal and the SESAM, and discuss the dispersion compensation technique. (NEDO)

    In a continuous casting of steel, the surface quality of a slab is strongly influenced by mold oscillation. Recently. a new idea in which the imposition of an intermittent alternating magnetic field was synchronized with the mold oscillation has been proposed for the improvement of surface quality under a concept of 'soft contacting solidification'. The concept is based on the information that the reduction of the contact pressure between a mold and a melt under the imposition of an alternating magnetic field results in good surface quality. However, the most suitable timing for the imposition of the magnetic field in a mold oscillation cycle still has not been determined. To clarify the behavior of the surface wave motion, which is closely related to the contact pressure between a mold and a melt, we have conducted a model experiment on the free surface motion of a molten gallium excited by the synchronous imposition of the intermittent alternating magnetic field and the simulated mold oscillation. The phase difference between the mold oscillation and the magnetic field has been studied from the viewpoint of the suppression of the surface motion. It has been found that the wave shape excited by the synchronous imposition agrees with the numerical superposition of the two wave shapes excited independently by the magnetic field and the mold oscillation, except for the case where a small surface excitation is observed.

    The authors have studied on surface treatment of PTFE by a low pressure discharge. It is deduced that excited nitrogen molecules contribute to introduce polar components on the surface. To confirm the speculation, we tried to change population of metastable nitrogen N2 (A{sup 3}{Sigma}u{sup +}) by quenching precursor N2 (B{sup 3}{pi}g), with hydrogen molecule. The decrease of relaxation time which indicates a change of excited molecule and measured by emission spectroscopy using a time after glow method was obtained. As a result, the relaxation times of N2 (B{sup 3}{pi}g) and N2 (A{sup 3}{Sigma}u{sup +}) decreased to 55% and 20% respectively, when mixing ratio of hydrogen was 3%. It was also deduced that hydrogen atom may take a part in a quenching process of N2 (A{sup 3}{Sigma}u{sup +}). 14 refs., 11 figs., 1 tab.

    It is clarified that the photo-excitation hydrophilic reaction increasing wettability remarkably is induced by changing surface structure of titanium oxide radiated light. There are already many examples being in practical use of coating products applied hydrophilic reaction of titanium oxide surface such as drip-proof side millers for automobiles, self-cleaning building materials, and the like. When surface of titanium oxide having high activities for oxidisation and decomposition is coated organic materials and radiated light, wettability of surface changes as organic materials are decomposed. If it is possible to change wettability shaping pattern drastically by radiating light, the possibility of application for printing materials will be developed. After increasing contact angle by coating water and oil repellent on the titanium oxide thin film, images can be shaped by radiating light into pattern for changing surface of titanium oxide to be ultra hydrophilicity as decomposition of repellent. At that time, contact angle is 150 degree in water, 80 degree in oil, for not radiated aria, and is 0 degree in water and oil for radiated aria. Application for control technology of wettability keeps possibility of broader development to itself, not staying ability of self-cleaning and drip-proof. (NEDO)

    Focusing on Phosphoenolpyruvate carboxykinase (PEPCK), recent knowledge on the transcription regulating function by carbohydrates via hormone is introduced. PEPCK exists mainly in the liver, kidney, adipose tissue, and small intestine, and the synthetic rate of PEPCK protein is regulated virtually by the transcription of PEPCK gene. Most part of the change is regulated via insulin and glucagon, and glucagon accelerates transcription while insulin suppresses transcription. Suppression by insulin becomes smaller in transgenic mice having reporter genes which lack RE containing part, but sufficient suppression of PEPCK gene expression by high carbohydrate diet is observed. Fasting and high protein diet increase glucagon concentration in the blood to increase cAMP concentration in cells. High PEPCK gene expression is observed with diabetes, which is the main cause for the increase in the value of blood glucose in diabetes. 20 refs., 2 figs.

    The relation was systematically examined between the surface quality of a rolled sheet in cold rolling and tribological factors (rolling speed, reduction, viscosity of lubricant, surface roughnesses of a roll and sheet). In the case where the surface roughnesses of rolls and sheets were smooth, the surface brightness decreased with an increase in rolling speed and viscosity, resulting in rough surfaces. The dependence of the rolling speed, viscosity and roughness on the brightness was equal to that on an oil film thickness, and the brightness of rolled sheets could be thus expressed as the function of only the oil film thickness. In the case those were rough, the roughness had a great influence on the surface quality of rolled sheets, and the brightness could be expressed as the function of the oil film thickness and roughnesses of rolls and sheets before rolling. Based on these relations, the system was proposed capable of estimating and controlling the brightness of rolled sheets from/by conditions before rolling. 13 refs., 16 figs., 1 tab.

    QoS control method which satisfies utilities communication network requirement and alternative route establishment method which is for sustaining communication during a failure are studied. Applicability of DiffServ (Differentiated Service), one of the most promising QoS control method on IP network and studying energetically in IETF WG, is studied and it is found most application used in the utility communication network except for relaying system information could he accommodated to the DiffServ network. An example of the napping of the utility communication applications to the DiffServ PHB (Per Hop Behavior) is shown in this paper. Regarding to the alternative route, usual IP routing protocol cannot establish alternative route which doesn't have common links and nodes in their paths for a destination. IP address duplication with some modification of routing protocol enables such alternative route establishment. MPLS, distance vector algorithm and link state algorithm are evaluated qualitatively, and as a result, we found MPLS is promising way to establish the route. Quantitative evaluation will be future work. (author)

    Measures for leveling electric power load has become increasingly more important issue than ever, whereas such measures are being taken as creation of demand for late night power supply or improvement in billing systems. This project is intended to establish technologies for load concentration control systems that can achieve electric power load leveling and can serve for reducing electric power cost ultimately. As the fifth year since the verification tests have begun in fiscal 1994 on load concentration control systems, July through September 1998 have carried out indirect load control tests and direct load control tests by using power information and charge information. Comprehensive analyses, such as confirmation of maximum power suppression effect and identification of users' reaction, were performed using the collected test data and the result of a questionnaire survey. The result revealed that the peak suppression effect by the indirect load suppression group exceeded that by the direct load control group. However, with respect to users' consciousness based on the power and charge information and the actual action patterns, further detailed analyses are considered necessary. (NEDO)

    This paper describes laser irradiation and velocity selective deposition experiments for fabricating high quality thin films. For the formation of Ag thin film by vacuum deposition method, YAG laser was irradiated to atoms or clusters parallel or perpendicular to the NaCl single crystal substrate, to deposit them on the substrate. For another experiment, Ag atoms selected in the given velocity were deposited on the (001) NaCl substrate by passing the molecular beam through the velocity selector. When laser was not irradiated, the thin film showed a random structure. Epitaxial growth was accelerated by the laser irradiation. When the selective velocity was set in 353 m/s at the constant intensity of molecular beam, the diffraction pattern of the thin film showed net pattern. When the selective velocity was set in 529 m/s, a structure in which ring pattern was overlapped on the net pattern was obtained. 2 figs.

    Fourier seismology capable of determining quantities related to elastic wave velocity dispersibility and non-elastic damping is under development, and studies are under way for the development of a sub-surface probing technology utilizing this seismology. It is deemed that the above-said quantities are related to the occurrence of earthquakes, behavior of sub-surface water, and migration of magma. In this method, precisely controlled sinusoidal waves are radiated and the received spectral data is subjected to cepstrum analysis, advantageous over other methods in that it achieves a high S/N ratio in a non-destructive way, facilitates deep structure analysis, and capable of monitoring changes with the elapse of time in such a structure. A newly-developed high-mobility transportable quake generator is described, which covers a wider frequency range and aims at the short-distance exploration of sub-surface conditions. Important components of the quake generator include an eccentric mass bearing capable of dealing with high-speed rotation enabling high frequency oscillation, variable mechanism for the primary moment of inertia, exciter and ground surface coupler allowing operations on a soft ground, and torque cancelling mechanism for the excitation of SH waves only. 3 figs.

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

The plan for development of the examination/failure diagnosis method, as the next R and D theme, is drawn mainly for determining positions of product quality standard setting-up, examination of individual steps and failure diagnosis functions of sewing machines, classification of the failure levels, and prediction of failure. Prospects of establishing an automatic system for visual recognition are obtained. (NEDO)

    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.

    A method for determining part re-use and recycling strategy in product design is considered for optimal design of total product life cycle based on the concept of Right Quality Products. For this purpose, it is important to be able to estimate part deterioration status under various product usage conditions. For supporting product designers' decision making about the product life cycle in preliminary design phase, the deterioration estimation is not required to be very exact, but to generate every possible deterioration modes qualitatively. Then, based on these deterioration modes, functional behaviour of target products is simulated, and possible product failure modes can be generated. By utilizing the FMEA (Failure Mode and Effect Analysis) method, the effects of failure modes are evaluated, and the results are fed back to product designers for confirming their design in terms of total product life cycle optimization. A basic methodology is considered, and case study has been done for a mechanical assembly of a one-time use camera. The assembly consists of injection molded parts. Various CAE methods have been used for predicting possible part failures due to initial residual stress, warp, fatigue, creep, and wear. Then kinematic and dynamic analysis of mechanical assembly has been done for detecting the effect of part deterioration on mechanism movements. Several critical failure modes have been detected, and the effects of those failures have been checked by the FMEA method. (NEDO)

    The high-temperature air combustion technology recently developed greatly advances combustion technology. The technology, when applied to the other areas, may expand its applicable areas and contribute to environmental preservation, e.g., abatement of CO2 emissions. This is the motivation for promotion of this project. The combustion technology, developed by improving functions of industrial furnaces, cannot be directly applied to the other combustion heaters. This project is aimed at extraction of the problems involved, finding out the solutions, and thereby smoothly transferring the technology to commercialization. This project covers boilers firing finely pulverized coal, waste incineration processes and high-temperature chemical reaction processes, to which the new technology is applied. It is also aimed at establishment of advanced combustion control basic technology, required when the high-temperature air combustion technology is applied to these processes. In addition to application R and D efforts for each area, the basic phenomena characteristic of each combustion heater type are elucidated using microgravity and the like, to support the application R and D efforts from the basic side. This project also surveys reduction of environmental pollutants, e.g., NOx and dioxins. This report presents the results obtained in the first year. (NEDO)

    In order to produce the high quality rare-earth magnet, macrostructure control of Pr-Fe-B alloy ingot was carried out. Production method of this alloy consists of melting, casting, hot rolling and heat treatment. The columnar structure of ingot is necessary to obtain the high magnetic properties. The columnar structure was produced by two kinds of method. One is thin plate casting and the other is directional solidification. By the thin plate casting sound and columnar structure ingot was produced. This alloy is cooled rapidly from the liquids temperature to the peritectic temperature and then cooled slowly below the peritectic temperature because this alloy is brittle. By this method the columnar structure was produced and the crack of this thin plate was protected. In order to decrease the production cost of ingot, 400kg large size ingot was produced by the directional solidification using the hot top heating. The temperature gradient in ingot was so increased by the hot top heating that the large part of ingot showed the columnar structure. The magnetic properties such as (BH) max and iHc were improved by the hot top heating. 4 refs., 14 figs., 3 tabs.

    It is required to control microstructure and micro magnetic behavior in Co-Cr based alloy thin films strictly in order to apply these thin films to the ultra high density magnetic recording media. In this study, thin film deposition technology to control nano-metric micro-structure and micro magnetic properties, especially in the distribution through thickness direction, were examined. Furthermore, to develop some evaluation technique to determine such local distribution of magnetic properties was one of the purpose of this study. The relationship between c-axis orientation of crystallites and distribution of the perpendicular coercivity H{sub c} in Co-Cr films has been investigated through the evaluation of the the H{sub c} of surface layer H{sub c}(s) measured by Kerr hysteresis loop tracer. Better c-axis orientation, higher Cr content and addition of Ta seemed to be essential requirements to get higher H{sub c} of initial growth layer H{sub c}(i) and good uniformity of H{sub c}. Lower {delta}H{sub c} caused better recording characteristics and lower media noise level. It has been clarified that the homogeneity of the magnetic properties in the film and c-axis orientation in the initial layer of the films were the essential factors to deposit low noise and high performance recording media.

    Many sensorless vector control systems have been proposed to increase the reliability and to reduce costs of the systems. However the parameters of an induction machine are changed by the temperature, the estimated speed may be incorrect value. When a constant torque drive system is constructed by a sensorless system and a current source inverter (CSI), the accuracy of the estimated speed influenced directly the response of the torque. In this paper, a direct field oriented control system is constructed by the flux observer which is low sensitivity to the rotor resistance variation and a proposed speed estimation scheme in a torque control system driven by a CSI. We compared experimental results by a voltage source inverter system and by the CSI system which is adopted our sensorless vector control scheme. At a lower speed condition, the system identifies the stator resistance, and we can estimate rotor speed correctly. Then the CSI system drives stably the induction machine without the speed sensor in a lower speed condition, and it can be applied to the constant torque drive systems. 7 refs., 17 figs., 1 tab.

    Transcription accelerating mechanism by glucose is discussed with relation to glycolysis enzyme rat L type pyruvate kinase isozyme (LPK) genes, whose expression is recognized in liver and {beta} cells, and rat insulin 1 genes whose expression is observed in {beta} cells of pancreas. Conspicuous increase of LPKmRNA amount in the liver is observed in the rats fed with high glucose diet. It is clarified that this effect depends on the insulin level in the blood and is caused by the transcription acceleration of LPK genes. Metabolism of glucose is considered to be necessary for this transcription acceleration. Synthesis and secretion of insulin in {beta} cells of the liver are also regulated by the glucose concentration in the blood. In any system, only one factor is not sufficient to respond to carbohydrates but interaction of multiple factors are required, and it is considered that they function as one unit. 22 refs., 2 figs.

    We report photo-generation of highly hydrophilic surface of titanium dioxide. The photo-induced hydrophilicizing is achieved by photo-generation of Ti{sup 4+} to Ti{sup 3+} at definite sites on the surface, resulting in preferential adsorption of hydroxyl groups on corresponding oxygen vacant sites. We also report the photo-generation of titanium dioxide amphiphilic surface on definite photo illumination condition. The unique character of this surface is ascribed to the microstructure of hydrophilic and oreophilic domain. The hydrophilic or amphiphilic titanium dioxide coating can be applied for antifogging mirror or glass and also self-cleaning paint for various industrial materials. Several commercial applications including antifogging automobile side-view mirror or self-cleaning exterior ceramic tile has been starting to hit the market. (author)

    This paper discusses sensor fusion for important driving environment information in an automobile control system, which utilizes external environmental information by using laser radar and CCD camera as the sensors. The paper also proposes an information-space-mapped sensor fusion system, which uses as the sensor fusion the spatial images to a system information space having as a spatial axis the conformity to control characteristics pattern to be selected from the sensor signal space. A configuration in which a design norm for the sensor fusion can be described declaratively was proposed by applying hierarchical fuzzy integration (HFI) as a means to realize image conversion. The configuration has realized a structure easy in system design and maintenance. In addition, the characteristics of recognition on driving environment of a driver were defined as perception sensitivity to psychological information on deceleration direction based on the affordance conception. This value was used for change in {lambda} value in fuzzy measures in the HFI processing to show the framework of a simple sensor fusion system. 26 refs., 9 figs., 2 tabs.

    An experimental study has been performed on the mean flow and turbulence properties of a two-dimensional jet impinging on a wedge having a circular cylinder with various diameters at the wedge vertex. The nondimensional profiles of the mean velocity in the fully developed flow region of the wall jet approach those of the conventional two-dimensional wall jet when a cylinder is attached to the wedge vertex and if the cylinder diameter is increased. Also both the slopes of the growth of the half-width and of the decay of the maximum velocity approach these of the two-dimensional case. The non-dimensional profiles of the turbulence intensities and of Reynolds stress in the fully developed flow region of the wall jet behave in the same manner, as mentioned above. In the variations along the wall of the integral value of the total production term of Reynolds stress, there exists the negative value region of it near the wedge vertex, and it extends as the cylinder diameter increases. 21 refs., 16 figs.

    Purpose of the work is to clarify the fundamental phenomena of laser welding, in particular the interaction of beam with plume and keyhole, keyhole dynamics in high speed welding, surface phenomena in laser soldering, defects formation mechanisms, and also to construct a mathematical model of laser welding based on the careful observation of phenomena with high temporal and spatial resolutions in order to establish the future monitoring and advanced control systems for the high efficient, accurate and functional and high speed laser processing. In this study have been clarified the spectroscopic characteristics and physical properties of laser induced plasma in laser welding, and defects formation mechanisms and their suppression methods which have been obtained by precise observation of dynamic behaviors of keyhole by the optical and X-ray methods with high temporal/spatial resolution. Also, mechanical properties of laser welded joints containing defects have been evaluated and the effect of porosity on static strength have been made clear by using the 2-directional X-ray imaging system during tensile test. Based on the above experimental results, a dynamic mathematical model of high speed laser welding was developed first in the world and the simulated results were qualitatively well coincided with the actual phenomena. Furthermore, wetting characteristics in laser micro-soldering, the metallurgical and thermal fatigue properties have been investigated, and revealed that laser soldering has much more excellent properties than the conventional processes.

    Research and development has been carried out on super metals with an objective to draw out properties possessed by iron and steel materials to their maximum extent and further enhance their recycling performance to make them friendly with global environment. The final goal of this project is to 'establish a technology to create micro tissue steel having crystalline particle diameter of about 1 {mu}mm or less and size having thickness of 1 mm or more by making the steel tissues uniform and multiple in phase'. The studies in the current fiscal year were moved forward mainly on obtaining ultra fine crystalline particles of 1 {mu}mm or less, identifying the ideal large distortion processing conditions, and structuring the guidance principles for ultra-fine micronization of the crystalline particles by using large distortion processing. Discussions were also launched on further micronization of crystalline particles by optimizing chemical composition and on expansion of the process windows assuming practical application thereof in industrial scale. Furthermore, material property evaluation was also begun on ultra-fine crystalline particle materials of smaller than 1{mu}mm. As the mesoscopic structure analyzing technology for the ultra-fine crystalline particle materials, an in-lens resolution SEM was introduced, and the basic method was established. (NEDO)

    A simulation method for switch analysis of ATM (asynchronous transfer mode) switch architecture has been developed. When various electric power information is integrated in the ATM switch architecture, delay priority control method has been proposed, by which the delay time and delay time fluctuation can be guaranteed for important information, such as system protection control information. The simulation method has been developed for analyzing the output buffer type crosspoint switch. The analysis solutions of waiting time of cells at the switch were determined and compared with the simulation results. The both agreed well mutually, and the validity of this method was confirmed. Priority was added to the cells of crosspoint switch, and different buffer was given for each priority, to exchange the important information, selectively. Thus, a switch was proposed, by which the delay time and delay time fluctuation can be restricted. The mean waiting time of the high class cells was suppressed less than 1 cts even at the switch load factor of 0.98, and the fluctuation range of 4 cts was guaranteed. 11 refs., 19 figs.

    Sport science progresses step by step in the world. The paper describes, the first, the relationships between fluid drag for a model of woman swimmer and the flow around it. The flow around the model swimmer is very complicated, and includes, for example, wave, some kinds of vortices, hydraulic jumping and so on. The complicated flows are visualized by the surface tufts method and so on. Second, the possibility of the reduction of fluid drag for a woman athlete swimming suit is challenged. The boundary layer control is applied to reduce the fluid drag. The separation occurs around the breast of a woman swimmer. The separation can be suppressed by the boundary layer control. Many beads are distributed on the breast area of a woman swimming suit. As the result, it is found that the fluid drag for the model swimmer can be reduced in a range of 1.5%--2% by the suit with the boundary layer control, which is carried out by many beads. 2 refs., 12 figs., 3 tabs.

    Notice was given on response characteristics in a short wavelength range of a large floating structure for an offshore airport consisting of semi-submersible replaceable type units, and influence of unit lacking. An attempt was also made on performing restoration of inclination change during unit lacking and suppression of long-cycle variation in waves by using air pressure control. The result of a numerical calculation based on a three-dimensional singular point method may be summarized as follows: mass force added vertically on columns in short wavelength range differs in the outer edges and the central part; relatively uniform values are shown in the central part; and interactive interference is recognized in wave forces in the vertical direction, but the influence therefrom decreases as the wave length decreases. Calculations on vertical movements and bending moments in waves were performed by using a mode synthesizing method. The calculations used fluid force which was calculated based on the three-dimensional singular point method utilizing symmetry with respect to each condition for a complete model plus unit lacking and unit lacking plus inclination control. As a result of verifying the calculations by using an experiment, relatively good agreement was achieved in either case. A high-frequency vibration experiment made clear the characteristics of elastic response in the short-wave length range. 14 refs., 14 figs.

    In introducing a photovoltaic power generation system to urban homes, the general practice is to install a large number of solar cell panels on the roof. However, as is often the case, a part of the solar cell panels is in the shadows (partial shadows) of neighboring homes, electric poles, cables and trees. Under the circumstances, studies were made on the numerous changes in the lowered generating capacity of individual solar cells by the partial shadows. Developed by the authors were the generation point control principle, in which the generation point was individually controlled on serially connected plural solar cell modules, and a practical circuit system based on that principle with the effects verified in a field test. In the test, the generated power of the system was 476W without partial shadows, and was 323W with partial shadows and without the operation of the generation point control circuit, increasing to 406W with partial shadows and with the operation of the circuit. As a result, compared with the case where no generation point control circuit was employed, the effectiveness of the proposed circuit was evident. 3 refs., 10 figs., 1 tab.

    Basic technologies are developed for the manufacture of high-quality crystal materials large in diameter and homogeneous in property which will allow power control semiconductor devices to grow more sophisticated in function and to be lower in the loss they suffer. Physical properties of molten semiconductor and the like are measured accurately, which include surface tension, density, viscosity, electric conductivity, thermal conductivity, emissivity, diffusion coefficient, vapor pressure, heat capacity, contact angle, and solid solution equilibrium distribution coefficient. In computer-aided simulation, as in the previous year, simulation codes are developed for the analysis of flow, temperature distribution, and diffusion behavior in the gas phase; simulation codes are developed for the analysis of 3D unsteady thermal flows in the melt; and a main program is developed which governs experimental calculations. As for experiments in model Czochralski crucibles, small crucible are used in which experiments are conducted in the temperature range of normal to 200degC for the acquisition of experimental data for verification. Measured by use of the model crucibles are the temperature distribution in the bath, the surface flow speeds, and the flows inside the melt. 140 refs., 153 figs., 10 tabs.

    Concerning the development of hydrogen combustion turbines, the paper described the fiscal 1997 results. As a hydrogen/oxygen combustor, the annular combustor was studied. Based on the results obtained by the last fiscal year, a combustor for the evaluation test was designed/fabricated. Oxygen is mixed with vapor at the portion of the burner, rotated/jetted (flame held by the circulation flow generated) and made to burn with hydrogen (porous injection). The smooth ignition and equilibrium wall temperature distribution were made possible. Concentrations of the residual hydrogen/oxygen in the stoichiometric mixture ratio combustion were both less than 1%. Further, can type combustor I is a type in which hydrogen and oxygen are burned near the burner and then are diluted by vapor. Improved of the burner structure and diluted vapor hole, it was tested. In can type combustor II, a mixture of oxygen and vapor is supplied and burned with hydrogen. The appropriate supply of oxygen was 20% distribution to the primary scoop and 80% to secondary. In both combustors, smooth ignition was possible, and concentrations of the residual hydrogen/oxygen in the stoichiometric mixture ratio combustion were controlled at minimum (approximately 1%). The evaluation method for the optimum hydrogen/oxygen combustor was studied. 142 figs., 24 tabs.

    A total of 49 budding yeast transcription factor disruptants and one conditional transcription over expression strain are produced, to elucidate the gene regulation networks using the gene expression profile data, and to measure the systematic and high-quality gene expression profiles using the Affymetrix's GeneChip system. The program is also developed for accurately predicting the base sequences which regulate expression of given gene groups, based on the uniqueness of the upstream sequences. The analysis with the aid of the program predicts 8 gene expression regulation sequences, which are considered to be novel, from the gene groups of retarded expression by the transcription factor disruptants. The time course gene expression data are produced from the transcription factor SW14 conditional over expression strain. The analysis of the data indicates that the analysis of the subtracted genes using the gene expression profiles from the wild type strain is useful for clarifying the effects of the derived transcription factor over expression.

    Since most prepainted steel sheets are usually formed for further working, these materials must have high workability (paint film with high deformation resistance). In addition, hardness and stain resistance inherent to steel sheets must be maintained. High workability is difficult to provide for steel sheets with high hardness and stain resistance. This is one of the reasons why the applications of prepainted steel sheets have been limited. This paper describes the study of the relationships between the paint film structure and the nature of polyester (PE) and melamine-formaldehyde (MM) resin. As a result of the study, the technology of control of orientation behavior of MM in paint film was established, and, with the technology, new prepainted steel sheets were developed to solve the problem above. In this case, formability (almost decided by the elongation percentage) depends on soft PE, while hardness and stain resistance (closely related to the paint film surface structure) depend on hard MM. The compounding ratio of the material was designed so that the MM bridge formation density is higher on the surface of paint film and lower inside the paint film, taking into account the reaction mechanism. Thus, the technology of densifying the MM surface has provided the excellent and unique performance for prepainted steel sheets. 5 refs., 6 figs., 4 tabs.

    Studies are made about ascochlorin and its derivatives which are expected to be effective in the treatment and prevention of lifestyle diseases such as arteriosclerosis, diabetes, hypertension, etc. The current goal is to definitely prove at the cell culture stage that ascochlorin and its derivatives act as ligands for nuclear receptors. As the result of the effort to prove their activation of nuclear receptors, it is clarified that they activate not only PPARr, which is the initial target of the research, but also PPARa, PXR, and ER. A computer simulation of interaction between ascochlorin derivatives and PPARr is conducted, and now it is predicted that the helix 10 cubic structure is transformed so that co-activators may connect to the structure. It is also found that AS-6 inhibits almost completely the appearance of type II diabetes in the db/db mouse lacking leptin receptors and type I diabetes in the NOD (non-obese diabetes) mouse. (NEDO)

    This R and D project is aimed at stable production of high-quality, important machine members, which are difficult to sufficiently achieve the required properties by a single material, by carburization while minimizing use of expensive alloy metals, where high-temperature carburizing time is reduced by a plasma-aided system to save energy, and, at the same time, the conventional oil-hardening system is replaced by a He gas cooling/recycling system to solve the environmental problems involved in the former. The exhaust gases released from the plasma-aided system are adequately treated to prevent the problems caused thereby. The conditions of the plasma itself and treated surfaces are sensed in-situ, and the data are fed back to the process controlling system, to keep the treated object stable and high in quality, while minimizing energy consumption.

    R and D was conducted for the purpose of manufacturing innovative iron-based alloy materials that excel in high temperature strength, toughness and superplastic forming, with fiscal 2000 results compiled. In the technological study on high-speed grain accumulation and superplastic forming, the researchers were engrossed in developing an aluminum bulk material of nano-crystals. This year, an Al-Fe two-element based alloy using Fe element was evaluated in the composition, thermal processing conditions and physical properties, with a bulk material obtained having a grain size of several tens in nm at 2at% Fe level, a strength of 750-850 MPa and a tenacity (Kc value) of 45-65 MPa(center dot)m{sup 1/2}. In the research of technologies for utilizing and controlling high density energy, design of materials was progressed for strong-acid resistant dew point corrosion materials, leading to the discovery of an alloy composition Ni-10Cr-5Nb-16P-4B whose subcooled liquid zone was wider than the Ta-added alloy of the previous year. Use of He gas as injection gas enabled a quality amorphous powder to be obtained in kg units. In the development of bulk amorphous producing technologies, this powder was thermostatically rolled to make a dense bulk amorphous plate of 2.8 mm thick and about 100 mm long. (NEDO)

    The acoustic excitation of a plane diffusion flame enhances the periodicity of organized eddy controlled combustion. In this study, to clarify an effectiveness of application of active combustion control, phase characteristics of the excited eddy flames with high periodicity have been examined. A computer-aided phase-locked averaging method was employed to obtain graphical two-dimensional contour maps of the instantaneous profiles of temperature and CH emission. Both maps consisting of eight consecutive phases indicated clearly not only the periodic behavior of the organized eddy flame, but also the gas dynamic properties peculiar to those flames with coherent structure. In addition, the profiles of local contribution of the sound field to the combustion process were examined by calculating the two-dimensional distribution of the local Rayleigh index. Calculation results of the two-dimensional distribution of the local Rayleigh index indicated that the organized eddy flames have high sensitivity to sound, and play an important role in an interaction of sound and flame. 6 refs., 9 figs.

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

    Assembly of International Space Station (ISS) is expected to be complete in 2010, with operations planned to continue through at least 2016. As we move nearer to assembly complete, replanning activities by NASA and ISS International Partners have been completed and the final complement of research facilities on ISS is becoming more certain. This paper will review pans for facilities in the US On-orbit Segment of ISS, including contributions from International Partners, to provide a vision of the research capabilities that will be available starting in 2010. At present, in addition to research capabilities in the Russian segment, the United States Destiny research module houses nine research facilities or racks. These facilities include five multi-purpose EXPRESS racks, two Human Research Facility (HRF) racks, the Microgravity Science Glovebox (MSG), and the Minus Eighty-degree Laboratory Freezer for ISS (MELFI), enabling a wide range of exploration-related applied as well as basic research. In the coming years, additional racks will be launched to augment this robust capability: Combustion Integrated Rack (CIR), Fluids Integrated Rack (FIR), Window Observation Rack Facility (WORF), Microgravity Science Research Rack (MSRR), Muscle Atrophy Research Exercise System (MARES), additional EXPRESS racks and possibly a second MELFI. In addition, EXPRESS Logistics Carriers (ELC) will provide attach points for external payloads. The European Space Agency s Columbus module will contain five research racks and provide four external attach sites. The research racks are Biolab, European Physiology Module (EPM), Fluid Science Lab (FSL), European Drawer System (EDS) and European Transport Carrier (ETC). The Japanese Kibo elements will initially support three research racks, Ryutai for fluid science, Saibo for cell science, and Kobairo for materials research, as well as 10 attachment sites for external payloads. As we look ahead to assembly complete, these new facilities represent

    Two groups of commercial quality (“acceptable”) pearls produced using two donors, and a group of “acceptable” pearls from other donors were analyzed using reflectance UV-Vis spectrophotometry. Three pearls with different colors produced by the same donor showed different absorption spectra. Cream and gold colored pearls showed a wide absorption from 320 to about 460 nm, while there was just slight reflectance around 400 nm by the white pearl with a pink overtone. Cream and gold pearls reached a reflectance peak at 560 to 590 nm, while the white pearl with pink overtone showed slightly wider absorption in this region. Both cream and gold pearls showed an absorption peak after the reflectance peak, at about 700 nm for the cream pearl and 750 nm for the gold pearl. Two other pearls produced by the same donor (white with cream overtone and cream with various overtones) showed similar spectra, which differed in their intensity. One of these pearls had very high lustre and its spectrum showed a much higher percentage reflectance than the second pearl with inferior lustre. This result may indicate that reflectance is a useful quantitative indicator of pearl lustre. The spectra of two white pearls resulting from different donors with the same color nacre (silver) showed a reflectance at 260 nm, followed by absorption at 280 nm and another reflectance peak at 340 nm. After this peak the spectra for these pearls remained flat until a slight absorption peak around 700 nm. Throughout the visible region, all white pearls used in this study showed similar reflectance spectra although there were differences in reflectance intensity. Unlike the spectral results from white pearls, the results from yellow and gold pearls varied according to color saturation of the pearl. The results of this study show that similarities between absorption and reflectance spectra of cultured pearls resulting from the same saibo donor are negligible and could not be detected with UV
