When a part of the ground is replaced with artificial materials in the construction of important structures on soft rock foundations, it is desirable for the artificial materials to have the rigidity equivalent to that of the surrounding ground and to be stable in the long term. The article reports a success in the development and utilization of artificial soft rocks satisfying the above conditions by using a raw material produced locally at the construction site. The soft rock aimed at was mudstone belonging to the Neocene period, and the artificial material of soil-mortal system is selected as the equivalent having the same physical properties. Improvements in selection of solidification agents and cohesive soil were especially contrived: taht is, a new material for solidification was developed by mixing blast-furnace cement and gypsum; and the mudstone on the site was used as the cohesive soil by slurrying it to adjust its grain size to homogeneous composition. The artificial soft rock resulting from the above contrivance showed excellent flow, self-leveling, and filling properties at the stage of fresh mortar, and the physical properties after hardning was very similar to those of the natural ground. The long-term stability was also confirmed by the tests on hydration reaction and environmental factors. 2 figs., 1 tab.

Combustion synthesis of porous titan carbide is outlined. In combustion synthesis, exothermic chain reaction, which is induced by igniting at one point of the simple substance mixture, propagates the combustion wave, and the compound is synthesized, which can be sintered by it. By this method, to this day intermetallic compounds, ceramics and high melting point composite materials have been synthesized, and synthetics can be made compact by adding pressure during or just after the reaction. Recently, applying the induction heating jointly, preheating before the reaction and heat treatment after the reaction can be controlled, accordingly, many high melting point inorganic compounds and composite materials can be made by combustion synthesis under pressure.

Studies to utilize bistable spontaneous polarization of ferroelectric materials for non-volatile memory have already been started in the 1950`s. Recently, a possibility was indicated on a high-speed non-volatile RAM (FeRAM) with memory cell configuration combined with switching transistors as in DRAMs. This situation has led to performing very active studies on ferroelectric materials and electrode materials used in ferroelectric film cell capacitors. This paper summarizes the above research and development circumstances, as well as their future problems. On the other hand of having shown excellent fatigue resistance in the SrBi2Ta209(SBT) system, improvement has progressed steadily on the Pb(ZR, Ti)03 (abbreviated to PZT) system, which retains the mainstream position as the ferroelectric material for FeRAMs. Aiming at realizing a high integration FeRAM in the future will require discussions on property changes due to use of lower temperature and micronization in film formation, further improvement in relation with degradation such as in imprint, and elucidation of the mechanism. 31 refs., 3 figs.

An imbalanced current distribution is often observed in cable-in-conduit (CIC) superconductors, which are composed of multistaged, triplet type sub-cables, and deteriorates the performance of the coils. Therefore, it is very important to analyze the current distribution in a superconductor and find out methods to obtain a homogeneous current distribution in the conductor. We apply a magnetic flux conservation in a loop contoured by electric center lines of filaments in two arbitrary strands located on adjacent layers in a coaxial multilayer superconductor, and then analyze the current distribution in the conductor. A generalized formula governing the current distribution can be described as explicit functions of the superconductor construction parameters, such as twist pitch, twist direction and radius of each layer. It is shown that we can obtain a homogeneous current distribution using this fundamental formula, which is a function of the twist pitches of layers. Moreover, it is demonstrated that we can control current distribution in the coaxial superconductor. (author)

The necessary conditions for biocompatible materials such as human bone, joints and teeth are mainly classified into biological condition and mechanical conditions. The former condition is consisted of chemical stability without causing poisoning or allergy, compatibility of good biological tissue, no carcinogenesis and not antigenicity, no decomposition and degradation inside human body, not causing adsorbate or precipitate. As for the latter, appropriate static strength, elastic modulus and hardness together with the characteristics like fatigue resistance, wear resistance and lubricating properties are given. As for other conditions for biomaterials, characteristics as a functional material, workability, adhesion and so forth are important. When surface nitrification of sintered Ti, forging Ti, sintered Ti-6Al-4V and forging Ti-6Al-4V is carried out, the solubility is decreased significantly by surface nitrification. The powder generated by the wear of nitriding Ti-6Al-4V with ultra high molecular weight polyethylene (UHMWPE) is less cell poisoning than the powder caused by the wear of the other alumina, stabilized zirconia, hydroxy apatite with UHMWPE. 16 refs., 2 figs., 1 tab.

In order to control the damage like crack or void formed during the use of structural material by the material itself, it is required to self-detect the damage, to self-judge the state of damage, and to self-control or self-repair the damage finally. Based on the parameter of length, the repair and control is classified into the 1mm-scale functional fine wire and thin film utilization type, 1[mu]m-scale microcapsule type, and 1nm-scale trace element utilization type. For the damage repair and control of functional fine wire and thin film utilization type, the damage is repaired and controlled by pasting thin film or by embedding fine wire of functional material, such as shape memory alloy, Ti-Ni, and piezoelectric ceramics PZT (lead zirconate titanate), on the material surface or inside the material. For the damage repair and control of microcapsule type, is illustrated the control mechanism of high temperature fatigue crack propagation by Y2O3 particles dispersed in the Fe-20Cr alloy. Furthermore, the formation mechanism of self-repairing film by the trace element is also illustrated. 13 refs., 5 figs.

R and D on harmonized molecular materials aim at establishment of the technology fabricating self-assembled organic molecular films on solid surfaces which have potentials of mechanical response to electric fields, electroluminescence or optical functions. Molecule harmonization expresses new structures and functions difficult to be expressed by each molecule alone, by cooperative interaction between molecules due to noncovalent bond. Functional thin films were developed by controlling alignment and/or arrangement of molecules with an aid of self-assembling processes. Thiol compounds with larger dielectric anisotropy were synthesized as electric field responsive self-assembled films. {pi}-conjugated compounds composed of phenyl-capped oligothiophenes were synthesized as electroluminescent self-assembled films, and their high crystallinity and efficient electroluminescence were found.

This invention relates to provision of a photocatalytic film on the light intercepting surface for the solar cell substrate of the solar cell element, which transmits the lights in the wavelength region longer than ultraviolet, i.e. 410nm and longer wavelength lights, and intercepts the lights in ultraviolet wavelength region. This photocatalytic film retards the decrease in the light interception by the solar cell element, and simplifies the maintenance because it oxidizes and decomposes organic matters by the less than 410nm ultraviolet ray contained in the sunlight to prevent adhesion of organic substance on the light intercepting surface of the solar cell element. In addition, decomposed dirt composition is washed away to accelerate dirt removing performance by rain waterdrop adhesion on the intercepting surface when it is used outdoors. As to this photocatalytic film, the thickness from 0.01 to 0.5{mu}m is desirable, effective phtocatalytic activity can not be expected if the thickness is less than 0.01{mu}m, and transmission factor becomes smaller if the thickness exceeds 0.5{mu}m, producing no electromotive force.

Aluminum, GFRP and composite of aluminum coated with carbon as structural materials for wind turbine blades were bending-tested, to improve blade bending stiffness, understand stress conditions at each position, and clarify structural dynamic strength by the bending-failure test. It is possible to estimate stress conditions at each position from the test results of displacement and strain at each load. The test results with GFRP are well explained qualitatively by the boundary theory, known as a theory for composite materials. The test gives reasonable material strength data, useful for designing wind turbines of high functions and safety. The results of the blade bending-failure test are in good agreement with the calculated structural blade strength. It is also found that GFRP is a good material of high structural strength for wind turbines. 8 refs., 6 tabs.

This paper describes the semiconductor packaging and molding compound materials. Major constituents of the molding resins are epoxy resin and inorganic silica, to which various additives are added. In order to make thin packages, biphenyl-based resins with low viscosity are often used in response to high fluidity. To fill the clearance less than 100 {mu}m, size adjusting techniques of the inorganic silica are also significant apart from resins. Since it is heated under the water absorption condition for the packaging in substrates, low water absorption, high adhesion, high strength and low stress are required to avoid peeling and cracking due to the vapor pressure of moisture. Generation of voids is also a problem. Improvement of productivity by reducing the processing period is also significant. In response to the strict environmental regulation, disuse of brominated epoxy and antimony oxide which are flame retardants in the molding resins is an urgent problem to be solved. For the epoxy resins, bisphenol A is to be regulated as a mutation substance. The cost reduction is required with keeping current quality kept. 1 fig.

Collected in this report are the outline of the research and development of spintronic device technology, its current state and tasks and its importance from social and economic viewpoints, and the strategy that Japan should follow in the research and development of the technology. Important spintronic device technologies now attracting attention are mentioned below. The nonvolatile magnetic memory device MRAM (magnetic random access memory) is supposed to be the device which will enjoy practical application first among like devices. It is expected that the spin conduction device will lead to novel functions when the possibilities of the spin-dependent electric conduction phenomenon are further pursued. It is hoped that the spin optical device will be used as a light isolator, light spin logic device, field induced variable wavelength laser device, spin laser device, high-speed light switch, and so forth. It is necessary to watch the development of a spin-aided quantum computer which is still at the stage of basic study. (NEDO)

Element technologies were developed for the manufacture of superconducting magnetic bearing (SMB) with the purpose of putting to practical use a 10 MWh class high-temperature superconducting flywheel power storage system. This paper explains the fiscal 1997 results. A {phi} 180 radial type SMB was designed and fabricated that satisfied the rotational strength at 17,200 rpm for a medium-sized model for measuring characteristics. Compared with the bearing made in the preceding year, improvements in the bearing dynamics were contrived such as flux creep, load capacity and rotational loss, with the maximum flux density improved by 30%; however, only a few percent improvement was attained in field uniformity. An SMB characteristics measuring and testing machine was built, with the characteristics measured. It was confirmed that the rotational loss of a control type magnetic bearing and the intrinsic performance of the testing machine were unchanged regardless of the operation/non-operation of the radial type SMB. The characteristics of the {phi} 180 axial bearing were measured by a stationary type bearing constant testing machine made in 1995, which provided a load capacity characteristics curve with the initially set gap as a parameter as well as a minor loop curve and a load capacity. Also obtained were the maximum average bearing pressure and the maximum load capacity. (NEDO)

Non-magnetization is applied to concrete structures with which magnetic environment is a problem, such as a guideway for superconductive magnetically levitated train system (Maglev) and geomagnetism observation facilities. As an example, this paper introduces the conception and the design methods of guideways for Maglev. If reinforcing bars or tensing materials of common steel are placed close to a vehicle, inductive current is generated in the steel due to moving magnetic field, causing a problem to form part of driving resistance. The inductive current includes loop current and eddy current. The former current may be prevented if the contact resistance in steels with each other is about one ohm or more, but the latter current has no other means but to minimize it as long as the material is electrically conductive. Conceivable measures may include the use as reinforcing bars of non magnetic high Mn-steel with electric specific resistance of 4 to 5 times as large as that for common steel reinforcing bars, and the use of continuous reinforcing fibers such as aramid. The latter material requires strength design especially importantly, but has obtained good result when it was constructed at the experimental linear motor train guideway at Miyazaki, Japan. 5 refs., 6 figs.

The design of biodegradable medical devices with molecular piston function is examined by utilizing the structure of polyrotaxane. A polyrotaxane in which {beta}-cyclodextrins ({beta}-CDs) are threaded onto a block-copolymer of poly(ethylene glycol) (PEG) and poly(propylene glycol) (PPG) is synthesized, and its molecular dynamics is evaluated in terms of the movement of {beta}-CDs along the copolymer. Also, polyrotaxanes in which {alpha}-cyclodextrins ({alpha}-CDs) are threaded onto a PEG chain capped with biodegradable peptide moieties are synthesized, and their degradation characteristics concerning {alpha}-CD release behavior are clarified. Cellular response to these polyrotaxanes is examined as a bioactive molecule. The polyrotaxane composed of {beta}-CDs and the block-copolymer was synthesized, and both assembled and dispersed states of {alpha}-CDs were characterized along the copolymer in response to external stimulus (temperature). Further, the polyrotaxane composed of {alpha}-CDs and PEG were synthesize, and their facility as a drug carrier was evaluated in terms of the release of {alpha}-CDs triggered by the hydrolysis of terminal peptides. Also, these biodegradable polyrotaxanes were found to enhance the fluidity of plasma membranes and to regulate cellular activation (cytoplasmic calcium increase). Thus, the polyrotaxanes were concluded to be promising as novel biomaterials aiming for medical micromachines and polymeric drug carriers. (NEDO)

Computer chemistry was investigationally studied. The advance of theoretical chemistry is indispensable to the design of materials, and the theory and high speed computational method are expected which can simulate the real system with more accuracy. It is basic to simulate structures and physical properties of structural molecules and the aggregate, but the meso region, the intermedium region between structural molecules and the aggregate, has became regarded as important. Rough visualization models in high polymer materials and the progress of computational software/hardware of quantum chemistry/molecular dynamics such as catalyst become necessary. Seamless zooming is proposed as a concept of the software which simulates materials from micro/macro/meso viewpoints. Moreover, to make the most of computer chemistry, an integrated system is necessary which generally handles computational software, database, etc. For the development of software, indispensable is the demonstrative verification by a combination of experiments and researchers. Under a commission from NEDO, the investigational research was conducted as a leading study during fiscal 1996 and 1997 to view the course of the research. 17 refs., 37 figs., 5 tabs.

In this session for the new materials, almost all of them were the presentation on the fiber reinforced plastics (FRP). Based on these facts, the topics of new materials about PC centered around FRP, and consequently it was found that how it was expected as the new materials and how it is being watched with keen interest. Even in FRP, the presentations on the carbon fiber reinforced plastics (CFRP) and aramid fiber reinforced plastics (AFRP) were a little bit more than those on the glass fiber reinforced plastics (GFRP), and therefore they were felt to be predominant. Although the ones about a fundamental study on the material characters of FRP held approximately 70%, as a content, there were 6 presentations on the design and execution of the actual bridges in which FRP was used for the PC take-up materials and the oblique cable of cable-stayed bridges, consequently it was found that FRP did not stay at a study stage, and was already shifting to the actual application stage. However, at the current situation, there were many of experimental ones like the small scale bridges in the golf courses, and furthermore it can not be said that a guideline for the design and execution is sufficiently established. 2 figs.

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

This paper explains fiscal 1997 results of the development of technologies for characteristic analysis of superconducting magnetic bearings (SMB), the development aimed at putting a 10 MWh high temperature superconducting flywheel power storage system to practical use. Following fiscal 1996, calculation programs were prepared for a load capacity and bearing constant (spring constant, damping constant) on an axial type SMB, with validity of the program examined through comparison with experimental values. A finite element method was applied to a complex magnetic field by a magnet arrangement devised for the purpose of improving load capacity, dividing a superconductor into divided sections so that the effect of a complex magnetic field distribution could be reflected, determining the magnetization generating in each divided section by using a two-dimensional Bean model, and developing a method for calculating load capacity of each divided section by a magnetic moment method. A program was completed for calculating the load capacity and bearing constant of the entire bearing in the axial type SMB. The calculated value of the load capacity and the bearing constant showed a superior agreement with the experimental value. (NEDO)

In the United States, high speed transportation plan was approved in 1965, and research and development of the superconductive magnetically levitated system (Maglev) became active. Although research and development for design, construction, and test for 500km/h Maglev were started in 1974, the federal government ordered to stop in 1975 all the development projects of high speed transportation traffic systems, and the activity slowed down very much as compared with those in Japan, Germany, and other countries. In 1990, the National Maglev Initiative (NMI) project was established. The feature which is different from those of Japanese and German systems is 0.16g and larger acceleration, which allows to shorten the transit time between stations. Development plan for Maglev prototype was approved officially in November, 1991. Features of levitation, guidance, propulsion as well as the carriage lineup of the 4 systems conceptually designed in the NMI project are introduced. 22 refs., 4 figs., 57 tabs.

The nonvolatile MRAM (magnetic random access memory), which is the nearest to commercialization, is a tunnel device consisting of two sheet-shape ferromagnetic metal electrodes and an insulator film sandwiched between the said two electrodes, with the lower electrode magnetized only in one direction. The tunnel resistance changes when the magnetization direction in the upper electrode changes left and right (1, 0) according to an external writing magnetic field, and this enables nondestructive readout. The upper electrode magnetization direction remains unchanged thanks to hysteresis when the external writing magnetic field is turned off, and this allows the device to serve as a nonvolatile memory device. The device has a potential for higher speeds and enhanced integration. Much is also expected from a spin conduction functional device utilizing spin-dependent electric conduction, spin optical function device, spin quantum calculation directly utilizing quantum state, magnetic field sensor, etc. Their importance is great economically and socially, and technologies relating to magnetism and semiconductor should be merged for their further development.

The co-generation system using a solar cell has the disadvantage that the performance of a cell element deteriorates when the temperature rises. Therefore, the co-generation system in which a BiTe thermoelectric element and linear Fresnel lens are used was constructed. Moreover, the basic characteristics were confirmed and the characteristics of a system model were analyzed. A thermoelectric element area must be reduced to improve the generating efficiency. The generating efficiency depends on the temperature difference between thermoelectric elements rather than the thermoelectric element area. As the thermoelectric area gets lower, the generating efficiency will get higher. This inclination is advantageous on the economic side. The generating efficiency becomes low during operation at high temperature. As a result, the temperature supplied to the thermal load is set to the lower position (100 to 200{degree}C) so as to advance the validity of the system. Even if the co-generation temperature is low, a heat supply capability of 150{degree}C is sufficient for an industrial heat supply system because it holds a large majority of the consumption demand for the whole industry. 3 refs., 8 figs., 3 tabs.

The present report explained light weight and high strength materials which are strong against the corrosion and fatigue, and economical. Also explained were their joining technologies for the commercial jet plane production. Resin composites are acceleratedly used as light weight and high strength materials. Fiber to be used is heightened in strength by replacing the glassfiber by the hybrid and carbon fiber. As measures against the drop in both strength around the drilled holes, and compressive strength due to the separation between layers and dehumidification, which drop is a defect generated in the composite, improving measures are taken such as enlargement of allowable strain by carbon fiber of a medium elastic modulus, use of resin base hardly degraded by the dehumidification and diffusion of high toughness resin. Metallic materials are also heightened in characteristics. For the joining technologies, measures are progressively taken against the strength damage around the drilled holes and electric corrosion by fasteners in the composite. Also for the tightening of metallic materials, the fatigue strength is designed to be heightened by the introduction of compressive residual stress. Both thermal degradation and stress in the hardening process must be taken into consideration for the structure use adhesives which are mainly of an epoxy system. The corrosion control is indispensable at the time of etching for the metallic adhesion. The welding was also explained. 16 refs., 7 figs., 2 tabs.

Introduction of electric power storage equipment is sought, which will be discretely installed in power distribution substations. Therefore, elementary technologies were researched on 'manufacture of super-conductive magnetic bearings' intended for practical application of an electric power storage system of 10-MWh class using high-temperature super-conductive flywheels. Research and development has been performed on different kinds of super-conductive magnetic bearings which combine high-temperature super-conductive materials with permanent magnets. In order to measure the characteristics of the super-conductive magnetic bearings, measurements were executed on rotation loss, loading power and bearing constants. In the measurement of the rotation loss, a {phi} 180 axial type super-conductive magnetic bearing using an Sm-based superconductor ({phi} 180AxSMB2) was given various kinds of tests by using a rotation loss measuring and testing machine. The results were compared with those for the {phi} 180AxSMB1 using the YBCO-based superconductor and other SMBs. In the measurements for the other items, various items were measured on dynamic rotation properties of the {phi} 180AxSMB and {phi} 180RaSMB by using a static bearing constant testing machine. In discussing the loading power characteristics, the dynamic rotation properties of the {phi} 180RaSMB were measured, and the loading power characteristics were discussed on super-conductive magnetic bearings for medium size models and super-conductive magnetic bearings for large system FS.

We advance the development of high-temperature superconductivity current limiter using the normal conduction transition. Since the rated voltage is high with 66kV, we desire that solid insulation which consists of main insulating layer and multiple layers in semiconductive layer is conducted to the current lead which connects the ordinary temperature and very low temperature division. And, it is necessary to sufficiently decrease the void, since crack proof and dielectric strength lower, when large bubble exists in the main insulating layer. We use ethylene propylene rubber for the solid insulation of superconducting cable. Though filler has entered the EP-rubber, the formability lowers, when we put filler in, and the void becomes easy to be generated. Then, we produced the current lead insulation model using the EP-rubber without filler, and we carried out crack-resistant test and withstand voltage test. (NEDO)

Good riding quality of MAGLEV vehicle requires construction of its guideway to a high level of accuracy. This paper discusses the relation of the power spectrum density (hereinafter the PSD) made up of guideway construction accuracy and its deviation with the level of riding comfort. The discussion uses the 'riding comfort affecting coefficient' consisting of the unit construction length, vehicle's travelling speed, and vibration characteristics. The PSD, which has been used to evaluate track deviation in the iron wheel/rail system railways, is derived from the number of limit exceeded point, the value 'P' as a track deviation coefficient, and the PSD. The relation between the standard deviation in construction errors and the PSD was derived based on track construction methods. This calculation method is characterized by a function with a step form. The relation between the deviation and the level was quantified using this PSD. Its practicability was verified by a simulated re-inspection of the guideway deviation. Correlation between the level and the construction accuracy was elucidated, and a method for determining the criteria for construction accuracy was established. A side wall beam installing vehicle has been fabricated on a trial basis for a side wall system for the guideway, and installation accuracy tests are being carried out. 14 refs., 12 figs., 3 tabs.

The technical art `Bekko` is one of the traditional technologies in Japan, and the materials of `Bekko` are shells of hawksbills. However, the industry of `Bekko Work` has been facing a crisis recently, because the import of turtleshell is restricted. We have therefore tried to develop new materials as substitutes for the turtleshell by utilization of horn. The noteworthy aspects in this study are as follows: (a) It has been clearly established that the horn could be reformed with amber color similar to that of turtleshell by chemical treatment using hydrogen peroxide (H2O2). (b) It is also of interest that we produced new materials like `Bekko` by mixing horn powder and turtleshell powder at the appropriate ratio and molding them in the temperature range of 110-120{degree}C. 1 ref., 6 figs., 3 tabs.

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

Recent diesel engines require a higher performance and a longer life. Due to higher cylinder pressure, the operating load and temperature of piston pin bushings become higher. Therefore, higher load capacity, higher wear resistance and higher corrosion resistance are required for piston pin bushings. For this reason, we have studied the effect of components added to copper alloy upon the corrosion resistance and the effect of hard particles dispersed in copper matrix upon the wear resistance and the influence of hard particles on the machinablity of materials. Based on the experimental results, we have developed a new bushing material improving wear and corrosion resistance. 17 figs., 3 tabs.

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

For development of materials for heat exchangers under severe corrosion environment due to ultra-high temperature coal combustion gas, basic data were surveyed. On the study in fiscal 1996, the corrosion resistance of one kind of commercially available material and 2 kinds of created materials was studied by coal slag coating test. The commercially available material was subjected to high- temperature corrosion tests of 1500 and 1550degC for a long time. The result showed that SiC is most excellent in the above temperature range. On new materials, 7 kinds of Cr2O3 system ceramics such as Cr2O3-Al2O3 system and Cr2O3- MgO system were selected considering high-temperature corrosion resistance, and the optimum composition and fabrication process of the new materials were studied. High- temperature corrosion tests, and measurement of thermal conductivity and thermal expansion were carried out for every specimen. The result suggested that some materials of Cr2O3- Al2O3 system are promising. 23 refs., 76 figs., 23 tabs.

This paper describes humidity-sensitive characteristics, which depend on the host composition being PbCrO4 or Pb2CrO5, in the system PbCrO4 combined with various oxides, such as Al2O3, Fe2O3, ZrO2, SnO2, TiO2, ThO2, and Ta2O5. In order to confirm the predominant phase over elements in the system PbCrO4-PbO, the effect of composition and microstructure on the humidity-sensitive characteristics of thick film elements were examined. Consequently, it was found that the humidity-sensitivity in low humidity region increased as the host composition of elements changed from hydrophobic PbCrO4 to hydrophilic Pb2CrO5. It was also shown that these results can be interpreted by a humidity-sensitive mechanism proposed for hydrophilic Pb2CrO5. Furthermore, an absorption model of H2O molecules on to the surface of Pb2CrO5 in the PbCrO4-PbO system humidity sensor was provided. 4 refs., 12 figs.

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)

The rectification type current limiter with the current-limiting system of the new type which combined rectifier circuits with the direct current reactor has been proposed until now, and it has succeeded in the current-limiting test by the normal conduction reactor by the 6.6kV class model vessel. Since the loss of the conductor becomes fundamentally the zero, in the same current limiter, by using superconducting wire rod, because direct current always flows in the reactor, making into low-loss becomes possible.

In order to create new functional organic thin film materials, basic data were examined under micro-gravity. Polymerization of pyrrole was affected by micro-gravity after a few minutes from the beginning of reaction. Although relatively uniform particles were obtained, the particle size was finely dependent on conditions. Electrolytic polymerization of conductive organic thin films was yet unstable in reproducibility. On orientation control and thin film formation of protein under gravity-free environment, electrodeposited films were obtained using bacteriorhodopsin film suspension by applying voltage of 6.4V for 9s after 1s from falling. The reproducibility of the number and area of molecular layers was poor. On the study on the formation process of organic thin films, creation of homogeneous films is probably possible by filtration from suspension under reduced pressure under micro-gravity for a short time. Trial linear polymer tied in a row was obtained by capillary injection of dense polymer solution. The viscous fingering phenomenon of viscoelastic bodies under micro-gravity was compared with that on the ground. 11 refs., 36 figs., 1 tab.

This paper describes use technologies of organic materials for selecting them under various environmental conditions. FRP is superior in mechanical strength and chemical resistance, and suitable as anticorrosion structural materials. Its chemical resistance is dependent on matrix resins. Simple polyolefine system resin is superior in chemical resistance and cost, however, because of its poor mechanical strength, it is mainly used for small parts. The composite structure is used for middle tanks or piping materials where the inside surface contacting solution is lined with chemical resistant resins such as PP and PVC, while the outside surface is reinforced with FRP. Various lining materials and lining methods are used. The following materials are used for lining: liquid resin type one such as tar epoxy resin, melting powder type one such as PE, PP and fluororesin, laminated glass fiber type one using cold setting polyester and thermosetting phenol resin, compound type one of scale-like glass flake and resin, and rubber or plastic sheet material. It is important to select optimum material for lining. 1 fig., 2 tabs.

Solvothermal reaction is reaction under high temperature and high pressure, which is expected to fabricate new functional materials. In this study, the materials are classified into two fields, i.e., inorganic materials, metals and their composites and organic materials and their composites. The current status of R and D of production and processing technology in each field is surveyed and the prospect of it is discussed. For the inorganic materials, metals and their composites, it is explained that very fine metal oxide particles, complex oxides, single crystals, whiskers, compounds with layer structure, metastable compounds, ion conductors and catalysts with high ability could be produced only by controlling the solvothermal reactions in atomic order. For the organic materials and their composites, surveyed results of the solvothermal technique using non-aqueous solutions are mainly provided. The necessity of a national project for researches on the solvothermal reactions is proposed from the viewpoint of resource, environment and energy. 777 refs., 38 figs., 26 tabs.

Aiming at developing a semiconductor CO sensor applicable to the safety control of gas appliances, we carried out an extensive material search for promoters to In2O3-based elements. Among the elements added (0.5 wt%) with each of 12 transition metal oxides, the Co3O4-added one was outstanding in sensitivity and selectivity to CO at 200degC. Remarkably the sensing properties of this element could be improved further by the addition of Au (0.04 wt%). The doubly promoted element, Au(0.04 wt%)-Co(0.5 wt%)-In2O3, gave excellent characteristics in sensitivity to CO, selectivity to CO over H2 and other selected gases, and response rates at 250degC. The promoting effects of the additives were shown to originate from the proper enhancement of catalytic activity for CO oxidation. 11 refs., 9 figs.

As for the levitation vehicle system, the vehicle is equipped with superconducting magnets and is levitated about 10cm by the electromagnetic force that works between the push coil and levitation guide coil laid on the ground and it runs 500km an hour. But, the running resistance and energy loss called as magnetic resistance caused by the electromagnet phenomenon that generates between the superconducting magnets and structures (steel products) generate. In this paper, the magnet resistance generated in guideway structure of superconducting magnetic levitation vehicle system and its countermeasures therefor are introduced. The main countermeasures against the magnetic resistance are as follows. The steel products have to be as arranged as separated from the superconducting magnets as far as possible in the permissible design limit. Based on the analysis results the low magnetic steel would be used in an area within 1.5m from the strand of the superconducting magnet. The contact resistance of the joints part of loop-shaped components would be bigger so as to do not cause the loop current. And the big component would be divided into small parts when it is used near to the superconducting magnets. 5 refs., 10 figs.

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

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

Creation of new functional inorganic materials using micro-gravity environment was studied. Observation of an electrode interface phenomenon under micro-gravity clarified that time variation in interference fringe is dependent on current density and electrode thickness in ground experiment, while it is dependent on not electrode thickness but current density under micro-gravity. In fabrication of glass fine particles under micro-gravity, true spherical glass fine particles of 4-7{mu}m in size were obtained corresponding to a charge of 40mg by evaporation and solidification of sodium tellurate glass as raw material under micro-gravity. In fabrication of non-harmonic Pb-Zn system alloy, the homogeneous alloy texture of 5{mu}m level was observed which has never been observed in previous metal phase diagrams by fusion of 80atom%Pb-20atom%Zn mixture under micro-gravity and quenching from 500degC.

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.

Development was attempted on organic-inorganic complexes as nonlinear optical materials. The objective is to develop elements with SHG activity (generating second harmonics) to change a visible ray into an ultraviolet ray by inserting P-nitroaniline (pNA) into such solid acids having strong static electric field as zeolite, laminar compounds, and heteropolyacid, and utilizing the static electric field and the molecule coordination field of inorganic compounds. Used for the pNA{center_dot}Bronsted acid composite are HBr, HCl, HNO3, and H2SO4. The pNA that has a center of symmetry in the crystalline structure and does not generate the second harmonics shows SHG when it is formed into a composite with HBr. No SHG is recognized in other acid composites. This difference is due to the difference in the crystalline structure. The SHG activity was generated when pNA is loaded onto alumina and silica as solid oxides. When zeolites are used as carriers, no SHG was observed. A composite of pNA{center_dot}AlCl3 has high SHG intensity, which reached a maximum when the pNA/AlCl3 ratio was two. This composite showed four new peaks that belong to the SHG activity phase. 8 refs., 2 figs., 2 tabs.

In order to achieve smooth and efficient promotion of the development thereof, development of the related technologies inside and outside the country was surveyed and discussed. Comprehensive surveys and researches were also carried out on the common basic technologies by looking to the well-informed people for guidance on the research. This fiscal year has held joint committee meetings to which lecturers were invited to discuss respective problems in the research and development trends. In addition, as the domestic survey, the status of research and development at the Tsukuba University was surveyed on photo-responsive polymeric gels. Furthermore, as the survey on the overseas technological trends, information related to photoreactive materials was collected mainly on photochemical burning materials in the U.S.A., and the research trends were surveyed.

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

Investigations were conducted by simulation of breakage of inhomogeneous materials (rock) attributable to detonative loading, which simulation used the Days-2 Code. During the simulation, one-free-face blastings were used for testing a homogeneous structure, horizontal 2-layer structure, and horizontal 3-layer structure. Property values were assigned to the rocks on the assumption that they were sedimentary rocks such as sandstone or mudstone or hard rocks such as granite. As the result, it was found that a detonative loading resulted in shear failure in a sphere near the focus that was followed by radially developed cracks due to tension breakage, that more area is damaged in a soft rock than in a hard rock, that cracks due to breakage are produced by the overlapping of waves directly from the focus and those reflected from the free face in case of one-free-face blastings, that such cracks propagated along the soft rock layer in case there is a soft rock layer in a hard rock, but that breakage does not extend beyond the soft rock layer. 6 refs., 6 figs., 1 tab.

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

A technique is discovered for improving on the baking properties of cerium oxide which is one of the solid electrolytic materials for SOFC (solid oxide fuel cell). Cerium oxide, samarium oxide, and gallium oxide are weighed, each to the specified element ratio. The element ratio of cerium is fixed at 0.8 against the other elements except oxygen, and the element ratios of samarium or gallium are caused to change. Specimens containing gallium are designated as CSGa, those not containing as SDC. SDC baked at 1600degC and CSGa (1%) baked at 1450degC are similar to each other in terms of average grain diameter. Specimens with gallium added thereto can be baked at temperatures that are lower than these by approximately 150degC. The conductivity of CSGa (0.2%) baked at 1500degC is higher than that of SDC baked at the same temperature, and is similar to that of SDC baked at 1600degC. Baking is enhanced by the addition of 0.2% gallium. In the domain where more than 1% of gallium is in presence, conductivity lowers with an increase in the amount of gallium added. The conductivity of CSGa (1%) baked at 1450degC is similar to that of SDC baked at 1600degC. 4 figs., 1 tab.

A radiation thermometer was applied to the measurement and analysis of radiation temperature of the material surface. In this paper, the characteristics of the radiation temperature and the radiosity coefficient of gray body materials are investigatied. An infrared radiometer was used, which detects radiation energy in the region between 8 and 13{mu}m of wavelength. This infared radiometer has a Hg-Cd-Te photon radiation sensor. The variation of emissivity was measured for the four kinds of non-metalic materials, i.e., graphite, carbon fiber composite, Si-SiC ceramic, and black paint spread on an aluminum plate. As a result, the relationship between material temperature and radiation energy was made clear. Furthermore, the space-dependent variation of the radiation temperature and the radiosity coefficient was derived from the two-dimensional CRT image of the infrared radiometer. Consequently, the emmisivity variation gave a maximum for the carbon fiber composite surface rich in irregularity, and decreased in the order of graphite, Si-SiC, and black paint. 7 refs., 15 figs.

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

Utilizing cooling properties and current voltage characteristics of a small cooling panel using thermoelectric elements which had been fabricated previously on a trial basis, design and prototype production were executed on a large radiant cooling and heating panel driven by photovoltaic cell modules. The panel design set the cooling area to about 0.5 m {sup 2} and the number of elements to 70 pieces, and optimum number of elements in series and parallel connection was derived. As a result of the analysis, it was made clear that the optimum number of thermoelectric module arrays in series and parallel connection varies depending on insolation intensity. It was found preferable that the number of parallel connection array be set to one to two in a region or time period in which low insolation intensity is distributed in greater amount. In the case where high insolation intensity is distributed in a greater amount, setting it to two to three is preferable. By using the structured design method and the HASP Tokyo data, thermoelectric element modules were interconnected with 35 modules in series and two in parallel on a cooling panel installed on the roof of the Science University of Tokyo. A simulation result revealed that the average temperature difference on the cooled surface in summer is 4.37 degC, and the solar cell utilization rate is 0.67. It is necessary in the future to improve heat dissipation efficiency and area ratio. 1 ref., 12 figs., 5 tabs.

Research, development and evaluation were performed with an objective of establishing the basic technology related to ultra-grid elements. With regard to the process technology to search materials suitable for the targets of ultra-grid elements and manufacture ultra-grid element structure, a technology has been completed, by which crystalline growth is performed while controlling AlAs and GaAs at atom layer levels by using the MBE process and MOCVD process. This has allowed the understanding to be progressed on behavior of electrons in hetero interface or very thin films. It has also become possible to acquire new crystals that have band gaps and grid constants matching the performance of the elements. Regarding ultra-grid functional elements, new functional elements with the HET and RHET structures were made by utilizing the characteristics of the ultra grids, and performances of normal temperature operation and high speed operation were investigated. The ultra-grid structured elements have made it possible to embed ultra fine electrode structure into crystals by means of double hetero growth, and a possibility of Si-based PBT was demonstrated.

The transportation system using simple magnetic levitation system got in the combination of high-temperature superconductivity bulk body and permanent magnet, which caught a quantum magnetic flux, is devised in great numbers, and the model equipment has also been manufactured. In the meantime, a grasp of levitation and guide characteristics is necessary for the case in which this levitation system is applied to the simple individual transportation system, and the measurement of the levitation characteristics is indispensable for the reason. In the conventional research, the measurement of the levitation characteristics has not been very much made. There was due to be no technique which measured kinetic characteristics of noncontacting surfacing and running travel body. In this study, measuring method for measuring these levitation characteristics was devised, and it was applied to actual measurement by the production of the model test equipment. Through this measurement, the purpose of this study is to show with that it is applicable for the real test equipment as this measuring method judges possibility of application to simple transportation system.

The simple analysis method of persistent current induced in on-board superconducting coils was proposed for the vehicle of a superconducting magnetically-suspended train which is running in the magnetic field generated by armature coil current of a linear synchronous motor installed along a guideway, and the performance of the method is discussed through calculation based on typical models. As fluctuation of persistent current due to running was calculated with various parameter values under a normal running condition, fluctuation of persistent current induced was less then 1% of an initial magnetomotive force, having no adverse effect on the stability and reliability of superconducting magnets. Electromagnetic forces under a normal running condition could be predicted accurately enough by relatively easy-to-calculate constant current mode analysis. Double-layered armature coils were preferred to single-layered ones to enhance the stability of superconducting magnets by reducing fluctuation of persistent current. 10 refs., 8 figs., 1 tab.

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

The fiscal 1998-2000 results of efforts to develop cluster diamond (CD)-diffused solid lubricant composite materials expected to exhibit excellent lubrication are stated. Since friction greatly affects machine life and energy efficiency, friction reduction is an important task. Very hard and microscopic CD was utilized for the achievement of a friction coefficient of 0.08. A manufacturing technology for molds 10nm or smaller was developed, which enabled the development of a gear not larger than 8mm. The success will enable the operation of micromachines in the absence of lubrication which is impossible at present. A CD-aided functional layer creation technology was also developed. It is expected that the development and practical application of micromechanisms will make rapid progress in the 21st century. Much is expected from the creation, and goods with the achievement applied thereto, of advanced technologies whereinto non-lubrication, functional layer creation, and excellent heat conductivity are incorporated. It is quite significant that, since CD is available in any field as far as light-load low-speed sliding conditions are satisfied, sliding parts will be improved and service life will be prolonged.

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

Research, development and evaluation were performed with an objective of establishing the basic technology related to three-dimensional circuit elements that integrate functions at ultra-high density. For the basic technology of lamination, the SOI technology suitable for the three-dimensional circuit elements was developed, and it has become possible to manufacture high-quality multi-layered crystalline structure by means of annealing that uses laser and electron beam. In addition, a lateral epitaxial technology for solid phase was developed, and the base to be applied to the three-dimensional circuit elements was established. Furthermore, the technology to put thin film circuits together would be useful for high-density integration in the future. The three-dimensional circuit makes parallel processing in each segment possible, whereas a possibility was shown that the processing can be performed at much higher speed than before. Actually a prototype three-dimensional circuit equipped with functions for parallel processing and judgment processing was fabricated. The image pre-processing which has been impossible on the real time basis in the conventional two-dimensional integrated circuit was realized in a speed as fast as milli-second order. These achievements lead to a belief that the targets for the present research and development have been achieved. (NEDO)

In the field of developing technical means to measure directly the information processing function of living organisms, detailed analysis has become possible for the first time on spatial operation of nerve activities by using two-dimensional beam measurement operation on the nerve activities. In the field of aiming at modeling, a system to realize functions effective in terms of engineering was structured by incorporating into the model the functions specific to nervous systems of visual sense and motion. In the field of element technologies, a large progress was seen in the basic technology and evaluation technology such as design and fabrication of molecules added with different functions in the LB membrane. Membranes having simple but different functions such as light beam and scent detection were manufactured, whereas a possibility of having them manifest functions as elements was verified. Furthermore, possibilities were discovered in manufacturing functional membranes by using self-organizing capability as a result of using basic properties possessed by polymers, and in realizing functions simulating plasticity of nerves.

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

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

Arc synthesis method, which is now the center for the synthesis of new carbon compounds such as carbon nanocapsules and carbon nanotubes, is introduced together with its current status. Many new carbon compounds are synthesized by DC arc discharge heating method (arc discharge method) in which a graphite bar is used as the electrode. C70 and higher order fullerenes having larger carbon numbers are found one after another in the soot produced by the arc discharge method, and the structures of C76, C78, C84, C90, C94, and others have been clarified. It is considered in the arc discharge method that the processes of a large amount of carbon evaporation by high temperature and the succeeding quenching cause to produce various kinds of new carbon compounds. In connection with other synthesis methods, synthesis of fullerenes by incomplete combustion, synthesis of nanotubes by the vapor phase thermal decomposition method, and the synthesis of nanotubes using casting molds are discussed. 24 refs., 6 figs.

Development of new materials with both thermal resistance and thermal shock resistance was studied on the basis of symmetric ceramics/metal/ceramics gradient composition. Al2O3/TiC/Ni/TiC/Al2O3 was used as material model of basic composition, and the system was selected where WC-Co system alloy hard particles were dispersed into the Al2O3 ceramic surface layer. The layered material was sintered in N2 gas atmosphere by SHS/HIP method using exothermic caused by nitriding reaction. Since cracks were generated in some specimens of 5-layer structure, improved specimens of 7-layer structure were prepared. To examine the effect of a particle size on toughness, WC-Co system alloy specimens with different particle sizes were also prepared. As a result, no cracks were found, and residual stress and fracture toughness were affected by particle size. In addition, the following were studied: technique of mass production, observation of fine structures, analysis of thermal stress, thermal shock resistance, and friction and abrasion characteristics. 13 refs., 65 figs., 15 tabs.

As part of the research, researches were carried out on small-size and middle-size models, low-loss control type magnetic bearing, and large-size models. For the small-size model, as a result of performing performance tests on the protective bearing by using a testing machine, it was revealed that the model is free of problems in the test for up to 5000 rpm. For the middle-size model, fabrication and installation were completed on a middle-size rotation control testing equipment having CFRP-made flywheel with a diameter of 1 m. In the control type bearing, as a result of adopting a homo-polar type magnetic pole, the rotation loss was reduced to about 1/5 of that of a hetero-polar type. The amount is about 75 W (12000 rpm) when the bias current is 1.5 A. Concept design was implemented on a 2-MWh flywheel bearing system supported with a high-temperature superconducting magnetic bearing as a full-size flywheel.

A composite material was prepared with carbon fiber (CF) and a matrix of phosphate (as named ACP) mainly consisting of aluminum phosphate. CF was used in the form of felt cloth. Prepreg was made with CF and ACP, which was laminated and formed under pressure in a hot press into a composite. The prepreg was pretreated by drying at 80{degree}C to form a compact matrix and to increase the adhesion between laminated prepregs. At the hot press treatment thorough removal of water was tried by using absorbent sheet and release sheet to form a compact structure. Consequently, porosity of CF/ACP composite decreased, and its bulk density and bending strength increased. SEM observation showed the formation of vitreous and compact matrix. Besides, adhesion between prepregs and shear fracture resistance were improved. 24 refs., 3 figs., 3 tabs.

Research, development and evaluation were performed with an objective of developing environment resistance strengthened elements, with emphasis placed respectively on radiation resistance, heat resistance, and integration degree according to specific requirements in the using environments. The objective for the first term is to develop the basic technology on element structures required to raise the environment resistance, and the methods of testing them. With regard to heat resistant elements, {beta}-SiC single crystal thin films were formed, and a prospect was obtained on using them as the elements. Regarding MOS integrated circuit, bipolar integrated circuit, and GaAs element, points presenting the largest issue in radiation resistance were noticed according to respective elements. Thus, temperature for gate oxide film formation was lowered, element structures were improved, and gate lengths were decreased to enhance the radiation resistance. For the evaluation test technology, a provisional testing method was prepared for the radiation resistance, a prototype in-situ irradiation testing device was fabricated and so was a prototype high-temperature testing device usable up to 500 degrees C. These achievements lead to a belief that the targets for the first term have been achieved. (NEDO)

Research, development and evaluation were performed in order to establish basic technologies to realize new information processing incorporating high-order functions of living organisms, and bio-elements equipped with high-order functions. In the field of developing technical means to measure directly the information processing function of living organisms, detailed analysis has become possible for the first time on spatial operation of nerve activities by using two-dimensional beam measurement operation on the nerve activities. In the field of aiming at modeling, a system to realize functions effective in terms of engineering was structured by incorporating into the model the functions specific to nervous systems of visual sense and motion. In the field of element technologies, a large progress was seen in the basic technology and evaluation technology such as design and fabrication of molecules added with different functions in the LB membrane. Membranes having simple but different functions such as light beam and scent detection were manufactured, whereas a possibility of having them manifest functions as elements was verified. Furthermore, possibilities were discovered in manufacturing functional membranes by using self-organizing capability as a result of using basic properties possessed by polymers, and in realizing functions simulating plasticity of nerves.

The following were reported on making Bi series superconducting thick films by a wet method. A paste was made by adding PSO (or ethanol solution of ethylenegrycol) of Yushiro Chemical Industry Co., Ltd. as a binder to a Bi series 2223 single-phase powder sample (blending composition Bi:Pb:Sr:Ca:Cu=1.8:0.4:2:2:3.2); the sample was then coated on an Ag (or MgO) substrate with a brush; after being dried at 105{degree}C for one hour, it was thermally decomposed at 700{degree}C for one hour; then, the process of prissurized forming (at pressure 2 to 5 ton f/cm{sup 2}) and of sintering at 845{degree}C for 20 hours or more were performed on the sample to form a thick film sample. A critical temperature Tc, critical current density Jc, etc., were measured on such thick film sample. As a result, nearly same values were obtained as Tc (93K) and Jc (84A/cm{sup 2}) which were those of a bulk sample made by using the same powder sample, pressurizing at 2 ton f/cm{sup 2} for pelletizing, and sintering at 845{degree}C for 20 hours. 6 refs., 7 figs., 1 tab.

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

In this study, preparation of porous adsorbent with developed micro-pores and meso pores and open pores on the external surface is tried. Namely, PFR-sawdust activated carbon is produced by carbonizing the PFR-sawdust composite materials obtained by adding KOH-immersed wood powders in the preparation of phenol-formaldehyde resin(PFR). Additionally, as a comparative test, KOH is added directly into PFR and PFR-KOH activated carbon is prepared by carbonization. Simultaneously with the clarification of the difference of pore structure between said two kinds of activated carbons, a various kinds of adsorbing tests are carried out to evaluate the adsorbing effects thereof. PFR-KOH activated carbon having a high specific surface area of 3500 m{sup 2}/g and a large number of micro-pore and meso pores is extremely effective in absorption of gas phase while the yield and particle strength are low. PFR-sawdust has a specific surface area of 1500 m{sup 2}/g which is the same level of activated carbons on the market, but the yield thereof is twice as that of PFR-KOH. 9 refs., 5 figs., 3 tabs.

MoSi{sub 2}-oxides composites using fine aluminosilicate powder (< 0.2{mu}m) have demonstrated excellent low temperature oxidation resistance and thermal shock resistance. These properties strongly depend on microstructural morphology and are obtained in composites that network-structures of both phases of MoSi{sub 2} and oxides are developed, i.e., in composites with oxides of 20 {approx} 40 vol. %. When one phase is independently dispersed in the other phase, on the other hand, problems of low temperature oxidation and thermal shock occur. The low temperature oxidation problem occurs in the composites with oxides less than 15 vol. % and the thermal shock problem occurs in the composites with oxides more than 50 vol. %. These results will contribute to material design approaches for high temperature structural applications of MoSi{sub 2}. (author)

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

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

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

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

The goal is to prepare a base for the development of polymerizing catalysts and precision polymerization processes which will enable the arbitrary control of molecular weight, regularity, branching, and primary structures such as terminal groups, which effort will lead to a remarkable advancement in condensation polymerization and open-ring polymeric material performance. Endeavors are on to fulfill two separate purposes, that is, precision condensation polymerization and controlled open-ring polymerization. In the study of precision condensation polymerization, at issue are basic studies and the development of precision control technologies for arrangement, molecular weight, branching, and matrix condensation polymerization. Also at issue are the development of technologies of position selective oxidization polymerization and precision conjugate high-molecular condensation synthesis. Concerning open-ring control polymerization, precision control technologies will be developed involving branching, molecular weight, crosslinking, arrangement, and the structure of cyclocarbonate open-ring polymerization. Open-ring control polymerization technologies are also under study by use of organic metal complexes. A survey of technological trends is also explained. (NEDO)

Described herein are the FY 1999 results of the R and D project for development of intellectual materials and structural systems, where the fibrous or leafy sensor material or element (muscle) is integrated with a structure of an advanced material (skeleton) to process and control information (brain). The program for development of the health monitoring technologies develops the fine optical fiber (diameter: 40{mu}m), which is on a level with the conventional 125{mu}m-diameter fiber in strength and fatigue characteristics, for the high-performance sensor systems. The self-diagnosis of soundness, e.g., detection of impact loads and damages, is attempted using the fine optical fibers embedded in the composite structures. The program for active-adaptive control of smart structures investigates control of vibration and noise for beam structure elements, using the theoretical model developed for shape memory alloys. The vibration tests are conducted, where a distribution type sensor is used for active-adaptive control of soft structures, and the good results are produced. The program for development of actuator materials and elements produces high-strength, high-toughness PZT and PNN-PZT sheets of uniformly distributed thickness by the doctor blade method. (NEDO).

R and D was conducted on a bio-functional material that is formed by synthesizing non-natural amino acids required for the manifestation of the function, incorporating the amino acids into new bio-functional peptides to be synthesized, and fixing the peptides on a substrate such as plastics. Activities were carried out in three areas, which were (1) innovative technologies for producing functional molecules, (2) R and D on materialization technologies of functional molecules: technique of pattern formation by photochemical reaction and of fixation, and technique of preparing peptide film using vacuum thin film forming technology, and (3) comprehensive investigation and adjustment. In (1), migration stimulating activity for microphage was selected as a molecular recognition evaluation system, and on the basis of the structural analysis result of a non-peptide compound/imidazolin compound having migration stimulating activity, molecular structural design was carried out for peptides having migration stimulating activity. The result of the analysis revealed that the spatial arrangement of three phenyl nuclei and the presence of basic structures were important. Among the 22 peptides so designed, only Cbz-Phe-Phe-His-NH{sub 2} showed the migration stimulating activity. For the design, a peptide molecule design system CHARMm/QUANTA/PM3 was used. (NEDO)

Basic technologies are established that equip polymeric materials (insulators in general) with conductivity similar to that of metals for the realization of novel conducting materials characterized by light weight, high resistance to corrosion, and ease of machining, and for the manufacture of novel electrical/electronic materials having new functions different from those of conventionally used metals. The aims are to realize a conductivity of 10{sup 5}S/cm or more, to manufacture materials sufficiently stable when left in the ordinary or inert atmosphere, and to manufacture materials which may be machined into proper shapes as required in the industry. The results of the 10-year-long development endeavor greatly contribute to the creation of high-level materials, the systematization of technologies, and the elucidation of the conducting mechanism. In relation to polymeric materials, in particular, a new technology is developed that equips, with high reproducibility, polymeric materials with conductivity similar to that of silver or copper; a graphitic material is created for the first time provided with conductivity superior to that of metals; and conducting polymeric materials are equipped with an easy-to-machine feature. A great contribution is accomplished to the production of superconductivity in organic charge-transfer complex crystals and to the elucidation of the conducting mechanism. (NEDO)

An experimental study was performed on a polyethylene composite material using knitted fabrics for a reinforcing pattern. The experiment used ultra polymeric polyethylene as a reinforcing material, and low-density polyethylene as a matrix. The reinforcing pattern used flat-knitted fabrics, fabricated by using a knitting machine. Formation temperature, which took melting points of both materials of 147 and 120 degC into account, was set to 145 degC with expectation on bonding of both materials. The tensile test was performed under displacement control of 10.0 mm/min, and after the test, SEM observation was conducted on fracture faces. The following findings were obtained as a result of the experiment: regardless of test piece cutting-out directions and the number of lamination, the fracture was observed in three stages; with two-layer test pieces, stress increased further from fracture strain at about 30%, and the test pieces ended up in final fracture while repeating increase and decrease in the stress; two-layer course test pieces showed tensile strength of 33 MPa, which is an enhancement by 51% of the strength of the matrix polyethylene; and fracture strain showed as high values as 70 to 90% in the two-layer test pieces. 2 refs., 6 figs.

This material ought to have an intelligent function including self-detection and self- restoration of defects, environmental harmony, high strength and long life. At present, these demands are implemented by embedding a sensor, actuator and controller in structure, or optical fiber, shape memory alloy and computer chip in matrix, however, such complex material structure has adverse effect on environment. On the other hand, single structure material such as biodegradable polymer is unusable in severe environment such as the ocean and space. These problems can be resolved by combining composite material and micro-sphere technology, for example fiber-reinforced plastic (FRP) composite structure including micro-capsules with nano particles.

Researches into organisms for their information processing, conducted in fiscal 1988 as part of a 'biological device research and development' project under the research and development system for basic technologies for the next-generation industry, are compiled into an article entitled 'information processing in neurons, and calcium ions.' The level of neuronal activity depends on changes in the level of nerve-membrane ion channel activity. Some kinds of ion channels are chemically activated (or inactivated) within the membrane. The phosphorylation of a protein ion channel is a typical case where an ion channel level is regulated chemically. In the muscarinic response of a neuron, a chemically operated ion channel plays an important roll relative to neuronal functions. In this response, a second messenger system in the neuron transmits extracellular information to the chemically operated ion channel. In this system, a calcium ion is one of important second messengers. (NEDO)

The composites consisting of {alpha}-quartz crystallites and amorphous SiO{sub 2} were prepared by HIP technique, imitating the structure of natural agate. In the previous study, the K{sub IC} of the composite prepared from the mixed powder of crystallites and amorphous SiO{sub 2} was comparable to that of the natural agate (0.56MN/m{sup 1.5}). In this study, to increase the toughness of the composite, (1) the mixture of silica sol and {alpha}-quartz powder and (2) silica sol including nucleation promoter were examined as starting materials respectively. These starting materials were pressed into powder compacts with {phi} 10 multiplied 50mm in size. The Pyrex glass capsule containing the compact was hipped at 800-1,200 degrees C for 0-120 minutes under the pressure of 200 MPa. The K{sub IC} of the composite obtained from the mixture of silica sol and {alpha}-quartz powder was equivalent to that obtained in the previous study, while the maximum K{sub IC} (0.63 MN/m{sup 1.5}) was obtained when PbCl{sub 2} was used as a nucleation promoter. The nucleation promoter having low solubility in water was useful for the homogeneous generation of the crystallites. (author)

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

Concerning the list-making for checking each element of the high temperature superconducting flywheel system, characteristics and reasons for employment of the small model and medium model were outlined in terms of the system structure (structure in single unit, structure in more than one units), flywheel, bearing, electrically-driven generator, etc. Also about the system in which no superconducting magnetic bearing is used, the information is collected in Japan and abroad through internet, etc., to outline the system. Further, main results obtained in the project were made public in main international conferences or academic meetings such as EUCAS and ISOTC108. At the same time, visits were paid to research institutes such as Cambridge University in the U.K. for the purpose of supplementing the survey so far made, to investigate the recent trend of the research.

For the purpose of evaluating the basic characteristics of high-temperature superconducting magnetic bearings (SBM), a system model is designed, experimentally manufactured and tested, which is embodied in the design/evaluation of a large-scale system, with an investigation carried out for the introduction of the system into an electrical power system. In this framework, an examination and research were conducted for the system design technology on which each component technology in the system structure can be applied consistently in the system. In the comparative assessment of various flywheel power storage systems, the specifications and achievements were compared in the component elements of the flywheel systems developed in Europe, America and Japan through the literature studies and the field survey, with examination performed towards the future development. As a result, it was found that, in America, bearings were all SMB's without control. Boeing's objective for the development is 10kWh or so in view of convenience for transportation and is prone to arrange it in numbers. Further, investigations were made in literature and documents on the domestic and international trend of development of high-temperature superconducting flywheel systems, elucidating the details of the development.

This R and D program is aimed at optimization of superconductors for improved levitation force of the superconducting magnetic bearings which support a 10 MWh power storage system by high-temperature superconducting flywheel (FW), to clarify possibility of sizing up the FW body and R and D themes for the commercialization. The processes are screened to simultaneously solve the conflicting targets of sizing up the sample of the Y-based bulk superconducting material and improved crystal orientation of the whole bearing, leading to selection of multi-seeding. The sample made on a trial basis improves levitation force by approximately 30%. It is considered that the OCMG-processed rare-earth-based superconducting material can generate very strong electromagnetic force, when combined with a permanent magnet. The Ag-doped Sm-based bulk material shows a reduced creep-caused loss of loading force, and a lower loss of Jc resulting from increased temperature than the Y-based one, decreasing AC loss and controlling temperature rise. The running characteristics and mechanical strength of the FW, and causes for temporal changes are investigated, in order to evaluate the superconducting material characteristics. (NEDO)

A microcrystalline Si thin film is used to form the i-layer of a narrow gap a-Si based thin film solar cell. Since a microcrystalline p-layer is to act as the seeding crystal layer for the microcrystalline i-layer, it has to be very high in crystallinity and therefore is produced under high hydrogen dilution conditions. In this process, a problem arises of the darkening of the underlying transparent SnO{sub 2} electrode. Since this is due to chemical reaction on the SnO{sub 2} surface layer, blackening is prevented by shortening the film fabrication time, and then an excellently microcrystalline p-layer is obtained. Furthermore, by inserting a microcrystalline i-film buffer layer of low fabrication rate into the p/i boundary, plasma damage on the microcrystalline p-layer is inhibited for the fabrication of a microcrystalline i-layer high in crystallinity at high film fabrication rates. A high Voc is then obtained even when the microcrystalline p-layer is very thin. If the hydrogen dilution rate is too low when the i-layer film fabrication rate is high, the initially fabricated layer turns out to be thick to the detriment of film performance. On the other hand, the p-layer or the buffer layer will be etched when the hydrogen dilution rate is too high. The problem is solved by continuously varying the hydrogen dilution rate from high to low during i-layer fabrication. (NEDO)

This paper refers to the development of basic technology for manufacturing crystal materials of a large diameter and uniform properties for the purpose of sophistication and low loss of semiconductor controlling elements for electric power. An experiment was conducted using the drop tower of the underground agravity center. Results in fiscal 1998 were explained. With counter-measures taken in for improving measuring accuracy of an electromagnetic floating furnace, the accumulation and evaluation were performed of the highly reliable data of the surface tension and density of Si. The measurement of the viscosity coefficient of Si under micro-gravity was successful for the first time in the world, as was the measurement of the contact angle between solid/liquid, other than the measurement of specific heat, thermal conductivity and spectral emissivity of Si. The viscosity coefficient, unlike the conventional report, showed Arrhenius' linearity. In the comupter simulation, boundary data were exchanged between element analysis programs, developing a basic general analysis program as scheduled. The result of a micro simulation by molecular dynamics method was in agreement with the observation result by a transmission type electron microscope, bringing the first success in the world. In the Cz furnace model experiment, effect of rotation for example was elucidated on turbulence in the melt by using lasers. (NEDO)

Recently, many of the low temperature materials such as LNG and LPG used as an energy substitution for petroleum were stored in the reclaimed land of the sea side district, however, it is necessary for those storage methods to enlarge sites. Therefore, it was considered to directly store the low temperature materials in openings excavated in the rock mountains. However, countermeasures for leakage of liquid and cold gas from cracks in openings would be an important subject. In this study, as a countermeasure for leakage of liquid and cold gas in the case in which low temperature materials were stored in openings in the rock mountains, the lining of resin materials on the surface of openings was proposed. Characteristics of strength and deformation and values of the thermal physical properties for the resin materials at the low temperature were obtained by experiments. This material was compared with granite supposed as a parent rock, and the thermal property of the resin materials was understood. Next, an analysis was conducted in the case of using the resin materials as a lining, the behavior of the surrounding rocks of the openings and the stability of the lining were investigated. 17 refs., 25 figs., 2 tabs.

Researches are conducted for the development of photofunctional materials, which will enable the utilization of such features of light as high speed, planar transmission, and space coupling, for the real-time processing of large-volume 2-dimensional image data etc. The researches cover the 'spatial light modulation material' and 'dynamic holographic memory material' which will be the key materials in the high-speed 2-dimensional data processing, and the 'optical waveguide material.' The 'spatial light modulation material' is a material that temporarily memorizes optical data for causing interference between images by use of light, the 'dynamic holographic memory material' is a material that memorizes phasal data of light and records and writes by use of light the large-volume data necessary for moving picture processing, and the 'optical waveguide material' is a material that transmits multi-dimensional picture data on the real-time basis. Researches are also conducted on the status of research and development of technologies involving novel photofunctional materials, the control of the structure of their electrode/molecule boundary, the creation of ultrastructural materials by molecular arrangement control, etc. (NEDO)

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

Slag released from an electric furnace consists mainly of waste steel. There are two types of slag, namely, oxidized slag and reduced slag. Reduced slag, which is generally in the form of powder, is difficult to recycle as compared with oxidized slag. However, with a hydraulicity, some reduced slag is expected to be useful as hydraulic material. Test results obtained here show that the hydraulic properties of reduced slag powder can be improved by mixing it with gypsum and that the resultant mixture can serve to improve the prooperties of soft clay. Another study is made to determine the potential, as hydraulic material, of mixtures of reduced slag powder and waste gypsum material with a high gypsum content released from an oxidized titanium production process. The hydraulicity is found to develop as a result of the formation of a hydrate of calcium aluminate which is contained in the slag. Addition of water to the hydrate and gypsum cause the formation of ettringite, leading to an increased uniaxial compressive strength. These findings indicate that the above-mentioned mixture can be useful to improve the hydraulic properties of coal ash to be disposed of at landfill sites. 5 refs., 5 figs., 1 tab.

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

Development was made on a technology to evaluate quality of composite materials. Few data are available for environmental resistance of composite materials, whereas identification of environmental deterioration behavior and establishment of a environmental resistance evaluating technology are a significant issue in utilizing these materials as new materials for space, aeronautics, and marine applications in the future. The present research was taken up with objectives to elucidate deterioration behavior of composite materials exposed to special environment in the atmosphere and space and to establish methods for acceleration tests and environmental performance evaluation by using simulated environments equivalent to the natural environment exposure. The former period (fiscal 1982 through 1984) has investigated environmental conditions in the atmosphere and space, prepared standard test specimens, performed design on environmental devices simulating the environmental elements, as well as tests on deterioration due to environmental elements, and systematized the deterioration characteristics to establish composite test conditions. The latter period (fiscal 1985 through 1988) has developed the composite environment testing device based on the result achieved in the former period, elucidated the deterioration behavior under the composite environmental conditions, and performed evaluation tests on the developed composite materials (FRP).

Researches are conducted for the advancement of, and loss reduction for, semiconductor devices for controlling electric power. Physical properties of molten semiconductors etc. are accurately measured in a microgravity environment and computer simulations are performed, which are for the production of larger-diameter, higher-quality semiconductor crystal materials. In the measurement of physical properties of molten semiconductors etc. carried out at JAMIC (Japan Microgravity Center) free-fall facilities where a high-quality microgravity environment is available, measurements are made of the surface tension, density, viscosity index, heat conductivity, and vertical spectral factor of the molten silicon. Solubility is measured of silica, silicon nitride, and silicon carbide, and, in equilibrium with these, the oxygen, nitrogen, and carbon in molten silicon, and highly reliable data are obtained. As for the comprehensive analysis code developed under this subject, the X-ray image data of the surface of a solid solution, collected from a crystal growing in a small Cz furnace at the NEC Fundamental Research Laboratories, and data of oxygen concentration in the silicon crystal agree excellently with the result of calculation, which suggests that the code is reliable.

This paper presents several topics on composite materials and describes the ways the materials should be for the future. Composite materials are accomplishing great evolution, which owes a great deal to application and practical use, particularly the progress in materials. However, an impression is ineffaceable that the technology stays in a limited region as a science to pursue basic principles. A development of the 'post-classical theory' is expected in the future. While fiber technologies are related closely with composites, Japan who has a long history of weaving, knitting, and braiding threads stands behind in devising ideas. Fiber engineering education would have to be addressed with problems. Rubber materials are made and used by freely using composite technologies such as carbon black mixing, vulcanization, and reinforcing with fibrous chords, but no through-design theory has been established. While wool has a function of self-adjustment according to humidity and temperature, such intelligent composites as ones using optic glass fibers for example are expected for their future. 1 fig.

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

The project aims to enhance the stability of amorphous solar cells. For elevating TCO (transparent conductive oxide) substrate transmittance to an ultrahigh level and for obtaining amorphous layers less to suffer photodegradation, efforts were made to develop substrate materials stable upon exposure to plasma and low in defect density. In the study of TCO, a high-transmittance glass substrate was employed and TCO was made thinner, and the specimen achieved transmittance of 91.3% or 6.3% over that of the conventional type. In the study of low reflection films, it was found that their transmittance came to be stable and remain so after 150 days after a weatherproof test. In the study for stability enhancement, optimization was carried out for a plasma resisting Ga{sub 2}O{sub 3}-added ZnO film for the manufacture of a substrate material capable of properly behaving in a high-speed a-Si film fabrication process. Low-temperature film fabrication was studied to enable low-cost manufacturing, and it was learned that a 4 times 10{sup -4} ohm/cm low-resistance film was obtained by sputtering Ga{sub 2}O{sub 3}-added ZnO where magnetism was intensive at room temperature, that films excellent in crystallinity were obtained by the same method even at low temperatures, and so forth.

Thick and large high-elasticity molded forms were obtained by searching poly-arylate material, and by developing such processing technologies as high-pressure injection molding, composite injection molding, and elongation fluidity molding. High-elasticity molded forms with uniform internal orientation were obtained by heating and molding liquid crystal polymers under high magnetic field. Solution molding was performed on a molecular composite consisting of rigid chains and soft chains, which was laminated and bonded to have obtained an isotropic form with as high elasticity as 54 GPa. In addition, high pressure powder formation of cross-linked polymers of di-acetylene system provided an isotropic form with sound wave elasticity of 23 GPa.

This R and D project is aimed at development of highly functional materials for aerospace devices, bringing into focus research and development of resin-based composite materials (FRPs), metal-based composite materials (FRMs), and evaluation of their properties and their design techniques. The basic target properties are heat resistance temperature of 250 degrees C or higher and tensile strength of 240 kg/mm{sup 2} or more for the FRPs, and heat resistance temperature of 450 degrees C or higher and tensile strength of 150 kgf/mm{sup 2} or more for the FRMs. This R and D program has been implemented for 8 years for development of raw materials, molding/processing techniques, quality evaluation and designs through information exchange and discussions of the experts in each area under integrated, close cooperation from raw materials to molding/processing. Most of the data indicate that the target properties and objects are satisfied or exceeded. It is therefore concluded that this project for the composite materials, extending for 8 years in 3 phases, has sufficiently achieved the initial objects. The unique techniques are incorporated in the raw materials, molding/processing processes, quality evaluation and designs.

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.

Development is under way of technologies for reducing pole-mounted transformer iron loss to 1/10 by developing materials which are low in loss, high in saturation magnetic flux density, and high in machinability, and for forming such materials. Development activities were conducted in three fields of (1) development of materials, (2) development of material manufacturing technology, and (3) fabrication of pole-mounted transformers and their evaluation. Under item (1), composition optimization studies were conducted for Fe-Zr-Nb-B based alloys, and materials to achieve target values were obtained. For improvement on formability, machinability, and soft magnetism characteristics in the atmosphere, alloys were tested, some free of Zr, others containing Mo, and still others with rare earth elements added thereto. Under item (2), improvement was achieved, for example, by giving high pressure capability to the dissolver of a vacuum compatible gas flow thin belt manufacturing device. An Fe-Zr-Nb-B based alloy 5kg in weight was formed into a 50mm thin belt, and data for large forming machine designing were collected. Under item (3), a toroidal core model was fabricated and its iron loss was measured after heat treatment, and a good result was obtained. (NEDO)

The research and development in the first term has searched widely different kinds of raw materials, elucidated electricity conduction mechanism, discussed processing technologies and evaluation methods. It also included molecule designing to develop new raw materials. A method for growing good single crystals of charge migrating complexes was developed, and (BEDT-TTF){sub 2}I{sub 3} crystals were found to manifest superconductivity at 8K under pressure of 1.3 kbar. In addition, elucidation was made on conduction characteristics of (TMTSF){sub 2}ClO{sub 4} being an induction superconductor, and on its superconduction mechanism. Polyacetylene films oriented at a high level by epitaxial polymerization were synthesized, the carrier hopping mechanism of polyacetylene was proposed, and the direction of increasing the conductivity was shown.

Studies are conducted for the development of now-unused kinds of fossil carbon resources, such as low rank coal and heavy gravity crude oil, into higher-value liquid fuel. In the preliminary treatment process, the fossil carbon resources are dried by use of supercritical carbon dioxide, when it is found that the resources are disintegrated and water is desorbed. In a low rank coal liquefaction process using the NiMo/KB (Kefjen Black) catalyst, more than 60% is converted into oil, which rate is improved by use of the dual-temperature liquefaction process. This catalyst may be recovered by separation utilizing specific gravity difference. As a low temperature gasification catalyst, the alkaline carbonate-carried carbon catalyst is very quick at the initial stage of reaction. The perovskite-carried alkaline carbonate catalyst is high in carbon oxidizing/activating efficiency at low temperatures. The silica film deposited on an alumina-coated support tube is excellent in selectivity and speed as a hydrogen separating film, and a carbonized polyimide film as a carbon dioxide separating film. For the supercritical phase adsorption/separation of chemicals not to be distilled easily, the NaY-type zeolite functions effectively. Pd/ZrO2 serving as a carbon monoxide conversion catalyst enables the recovery of more MeOH when Pd grains are smaller in diameter.

For the purpose of achieving remarkable energy conservation/resource conservation in large plants, the paper carried out an investigational survey of effects obtained in case of applying amorphous super metal which is the newest corrosion resistant material. Amorphous alloys as an ultra high corrosion resistant material are a peculiar material which shows the extremely excellent corrosion resistance even in much strong acid by containing passivated elements with the needed concentration. The corrosion resistant amorphous alloy applied to large plants need the thickness and diameter of more than several millimeters as a bulk material. The subjects are scaling-up of bulk materials and stabilization of characteristics. Even under the tough dew point corrosion environment of the waste power plant, etc., heat recovery from exhaust gas is made possible by heat exchanger applied with ultra high corrosion resistant materials. Effects of the annual heat recovery from the nationwide refuse incinerators and coal thermal power plants are estimated to be approximately 5.2 million kL toe, that is, to be equal to energy conservation of 6 x a million kW class power plant.

These technological developments are intended to develop technologies to manufacture with improved quality the silicon-based thin film solar cells. In order to analyze manufacturing conditions for micro crystal silicon thin films as the narrow-gap amorphous silicon-based films, films were manufactured in the vicinity of borders of amorphous/micro crystal silicon film manufacturing conditions. The present film manufacturing did not present effects of suppressing deterioration of hydrogen diluted light. In order to elucidate the light deterioration mechanism in hydrogenated amorphous silicon films and study the suppression thereof, discussions were given on impurities in the film, including oxygen. By using an ultra high vacuum plasma CVD having a thoroughgoing baking system, an oil-free exhaust mechanism, and a raw material gas refining mechanism, impurities were added to and removed from a reaction vessel, and an ultra-high purity Si:H film was manufactured, which has been removed of impurities from the raw material gas, resulting in reduction of O, C and N standing no comparison. According to the result of a light irradiation experiment on an ultra-high purity film obtained under an accelerated deteriorating condition by using a pulse laser, the model assuming the light induced defect and the pair of impure atoms has been denied.

The results of the second phase research and development project for developing the resin-based composite materials as the basic technologies of the next generation are evaluated. The second phase (FY 1983 to 1986) project is carried out to achieve the objectives, which are set up based on the objectives for the basic designs and the results of the first phase project. As a result, the concrete (promotion objectives), including those related to mechanical characteristics, have been almost achieved. For development of the highly functional FRP materials, the R and D efforts are directed to improvement of their moldability while satisfying the requirements of high functions, e.g., resistance to heat, leading to development of the basic techniques for epoxy resin-based intermediate materials. These results indicate possibility of commercialization of highly heat-resistant polyimde resin-based and novel resin-based intermediate materials. The results of the novel molding/processing methods, taken up in the second phase project as the ones which use no autoclave, are rated that they are developed to suggest possibility of the eventual commercialization, although the products they give are not always showing sufficient mechanical properties.

With the purpose of establishing innovative manufacturing technology for microstructure steel having a crystal grain size of about 1 {mu}m or less and a dimensional thickness of 1 mm or more by homogeneous multi-phase structure steel making, R and D was conducted, with fiscal 2000 results compiled. This year, R and D, using a multi-functional integrated test rolling mill, resulted in obtaining ultra-fine grained steel, a steel plate of 5 mm in thickness and 100 mm in width with grains of 1 {mu}m or less homogeneously in the thickness direction. In the investigation on the characterization by the steel plate sample thus obtained and on the method for preventing degradation in elongation, it was proved that an ultra-refined microstructure containing martensite or austenite as the secondary phase has a suppressing effect on the degradation in elongation. Further, examination was made on the widening of a process window for the practicability in the future and on the optimization of large strain deformation conditions. In the method of analyzing and evaluating ultra-refined microstructures, an analysis technology such as an in-lens SEM was proved to be extremely effective on the analysis of microstructures of supermetals created by large strain deformation as well as on the observation of microstructures of a submicron level.

A 1 T/D solvent-extraction type coal liquefaction test plant was constructed and operated to obtain the technical data for the design of, and establish the techniques for, an efficient coal liquefaction plant. The FY 1980 program includes surveys on the materials for coal liquefaction plants, covering those already developed and under development, to clarify the problematical points; drafting the test schedules; and conceptual designs of the material testing facilities. The major problems involved in the materials for coal liquefaction plants include erosion by fluidizing coal slurry, hydrogen embrittlement of the reactor materials, and corrosion by the liquefaction products (e.g., stress-corrosion cracking of austenitic steel, and corrosion by organic acids). The surveys on materials research trends suggest that USA seems to concentrate their research efforts on the reactor materials. The corrosion tests are mostly of in-plant tests, but the stress corrosion and slurry erosion tests are conducted on a laboratory scale. The conceptual designs are drawn for some testing units, e.g., the loop type material testing unit and basic testing unit for jet-spray type slurry erosion. (NEDO)

It also included molecule designing to develop new raw materials. A method for growing good single crystals of charge migrating complexes was developed, and (BEDT-TTF){sub 2}I{sub 3} crystals were found to manifest superconductivity at 8K under pressure of 1.3 kbar. In addition, elucidation was made on conduction characteristics of (TMTSF){sub 2}ClO{sub 4} being an induction superconductor, and on its superconduction mechanism. Polyacetylene films oriented at a high level by epitaxial polymerization were synthesized, the carrier hopping mechanism of polyacetylene was proposed, and the direction of increasing the conductivity was shown. It was discovered that cyanoacetylene is thermally polymerized at a relatively low temperature, turning into polymer with good orientation and easily into graphite. Polymeric intermediates soluble to polyparaphenylene vinylene (PPV) were synthesized, whereas these intermediates were found to have shaping and stretching properties, and conductivity of 2.8 times 10{sup 3}s/cm was obtained in PPV doped after the stretching.

For the purpose of energy conservation and environmental protection by effective utilization of unused waste heat, the R and D of thermoelectric conversion technology were conducted, and the FY 2000 results were summed up. In the investigative study of thermoelectric converting materials, evaluation was made of the materials having a possibility of achieving the target with the element efficiency of 6% and the assumed use temperature domain of 120-330 degrees C. The result of the study indicated that the number of new materials which were made public was increasing, but there were no materials that have evidently practical applicability. In the investigative study of element manufacturing technology, trial manufacture of element was made in which the investigative results were integrated into the existing 50W element manufacturing technology, and a target of 70W was achieved. In the investigative study of the thermoelectric conversion system for industrial and commercial/residential use, field survey and questionnaire survey were conducted for three fields of iron works, chemical plant and garbage disposal plant. As a result, it was found that there was a large amount of waste heat. By the study of the system conceptional design, it was found out that the output of 40-50kW can be obtained in the system structure suitable for the source of waste heat of iron works, etc. (NEDO)

Efforts are made to develop the above-named technology so as to improve on performance of magnetic materials for magnets extensively used in electric motors to consequently influence their energy conversion efficiency. For this purpose, probes are conducted into novel alloy phases, intermetallic compounds, and microstructure in a containerless coagulation process in which a molten body of a magnetic metal material in free-fall is allowed to cool rapidly, and a system is developed to enable a series of processes of heating and melting in preparation for containerless coagulation, specimen formation, and then coagulation in a microgravitational environment. The system is used for the study of novel materials for magnetic alloys and process technology. For the utilization of containerless coagulation in a microgravitational environment, it is necessary to make full use of the JAMIC (Japan Microgravity Center) facilities, and an experimenting apparatuses are fabricated for a containerless coagulation process and unidirectional coagulation process applicable to a free-fall test. In this fiscal year, some significance involving for example structural uniformity are found among the specimens created using containerless coagulation in a microgravitational environment, and it is inferred that the data as an index of higher performance will lead to studies in the next fiscal year and afterward.

As to high performance/high function plastic materials used in power generation facilities, technical trends were surveyed on the recycle situation and recycle R and D to study the subjects to be solved. For wire covering materials, vinyl chloride, polyethylene, rubber, etc. are used, and the recycle of resin has not been advanced. Concerning the generation of waste plastic, the existence of a lot of plastics different in characteristics makes the recycle difficult. As to the use of waste plastic as resource, the material recycle and recovery of combustion energy are being made, but only a part of the plastic is reused as chemical raw materials. Relating to the R and D of the chemical recycle technology, there are sample studies on the pyrolysis of polyolefine, dechlorination of chlorine base resins, etc. Recently, the following have been made public: proposal of depolymerization monomer based on the cyclic monomer, study of liquefaction of approximately 100% of the thermosetting resin, approach to the solvolysis by supercritical solvent.

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

Researches have been conducted on deca-nano quantum integrating transistor substrate technologies, and developments were made on a three-dimensional device simulator which can be used in deca-nano domains, and a circuit simulator to have quantifying function transistors coexist with silicon semiconductor integrated circuits. The researches were intended to develop a simulator capable of analyzing properties of very small silicon and compound semiconductor devices in deca-nano domains. The researches discussed the applicability of conventional simulators, calculated quantum levels in a three-dimensional hetero structure, and resulted in development of an electron wave propagation simulator in optional two-dimensional shapes, a quantum Monte Carlo simulator, and a three-dimensional semiconductor device simulator with quantum correction. On the other hand, in order to estimate characteristics of a hybrid circuit in which single electron transistors coexist with conventional transistors such as CMOS transistors, a single electron hybrid circuit simulator was developed. The development indicated that a CMOS-SET fused memory is promising as a future LSI memory. 22 refs., 116 figs., 3 tabs.

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

In the subject year, a multi-functional integrated test rolling mill was introduced, with possibility validated for grain ultra-refinement by three types of large strain deformation, and with the effect of deforming conditions confirmed. As for the theoretical understanding of the mechanism of grain ultra-refinement and the establishment of its guiding principle, a progress was made in clarifying the ultra-refinement mechanism particularly by the strain-induced ultra-low-temperature diffusional transformation, revealing for example that micro-bands formed in deformed austenitic substructures provided the nucleation sites for ultra-fine ferrite. In the evaluation of properties on medium size samples prepared by the multi-functional integrated test rolling mill, remarkable improvement was confirmed in yield strength and tensile strength in martensitic steel or tempered martensitic steel as well as in ferritic steel.

With the purpose of developing high strength alloys through grain refinement, R and D was conducted, with fiscal 2000 results compiled. This year, using hot rolled plates and cold rolled plates of 5083 based alloys, research was carried out on an optimum warm processing method for forming microstructures. When 5083 alloys were rolled with a large reduction by one pass under a warm to hot temperature range, recrystallized grain structures were obtained having 3-4 {mu}m in the surface and 7-8 {mu}m in the center. The proof stress of these specimens was about 1.3 times as strong as an ordinary 5083 alloy soft material while the elongation was about the same. In the case of 7475 based alloys with Zr added in place of Cr, a warm rolling method, in which the alloys were heated to 350 degrees C and repeatedly reheated by one pass at that temperature, was found effective in forming micro-subgrain structures. By the warm rolling method in which roll temperature was suitably heated, it was made possible to steadily form thermally stable microstructures in 7475 based alloys. The 7475 based alloy plate having a microstructure is superior to an ordinary 7574 plate in resistance against stress corrosion cracking. (NEDO)

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

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

It is intended to develop thin film solar cells capable of mass production with high photo-stability and at low cost. Thus, the objective of the present research is to analyze the growth process of micro crystal silicon based thin films, the crystal being a high quality silicon crystal based material, and develop technology to manufacture high-quality micro crystal silicon thin films based on the findings therefrom. It was found that, when silicon source is available in cathode, pure hydrogen plasma forms micro crystal silicon films by using the plasma as a result of the chemical transportation effect from the silicon source. It was revealed that the crystal formation due to hydrogen plasma exposure is performed substantially by the crystals forming the films due to the chemical transportation effect, rather than crystallization in the vicinity of the surface. The crystal formation under this experiment was concluded that the formation takes place during film growth accompanied by diffusion of film forming precursors on the surface on which the film grows. According to the result obtained so far, the most important issue in the future is particularly the control of crystal growing azimuth by reducing the initially formed amorphous layer by controlling the stress in the initial phase for film formation, and by controlling the film forming precursors.

Theoretical research was performed on the electron status of electrically conductive polymers, and on molecular designs. The research was made on the theme of the 'mobility of soliton in polyacetylene', wherein analysis was made on movements of soliton that carries charge in relatively low doping regions. Three researchers, Ono, Obuchi, and Iwano have proposed in the previous fiscal year the numerical simulation on the impurity effects with regard to the problems in chains of soliton. Its result is reported in this paper. In the current fiscal year, Ono has executed the simulation on the systems of even numbers having the total sites and electrons in the same number. Obuchi has applied the method discussed in the previous fiscal year to the cases having the total number of sites at 101, the number of electrons at 101 and 105, and the dopant concentration of 2 to 5%. Iwano has performed simulations on the bond type impurities for the case of even numbers with the total number of sites and electrons in the same number, the case with the total number of sites at 201 and the number of electrons at 200, and the case wherein the total number of sites is in even number, and the number of electrons in odd number.

Targeting at proposing to ISO as an international standard, R and D has been performed on a method of the alternating current heating of the non-constant method, with regard to a method to evaluate the thermal properties test on polymeric materials in molten condition reflecting thin film polymeric materials, and the forming and processing technology. This paper summarizes the achievements in fiscal 2000. The current fiscal year has executed surveys on literatures related to thermal properties, development and commercialization of a measuring device, establishment of the measurement procedure, and putting some of the materials into database. The database was prepared mainly for heat diffusion rate and heat conductivity, wherein about 1000 items of information were collected. The temperature range of the measuring device revealed that stabilized data can be obtained from as low temperature as liquid nitrogen temperature to as high as 200 degrees C. The commercially available measuring device has no restrictions if the test sample thickness is from 1 mm to 100 mm, if the temperature range is from room temperature to 350 degrees C, if the temperature rising rate is from 0.01 to 5 K/min, and if the test sample form is film. Measurement at temperatures including those in the melting zone in the forming stage of each polymer has achieved as close result as having been called for in the initial objective. (NEDO)

Study was made on cathodic protection of a roll bond heat collection board promising as Al plane collector. The protection is dependent on sacrificial anode materials. Al-Zn system alloy including minute amounts of In and Sn was effective in protection by transferring natural electrode potential to a base side largely, however, excess addition of In and Sn increased self-corrosion, remaining some issues to be solved. The prototype water flow corrosion test equipment was prepared for corrosion analysis of an Al roll bond collector natural circulation hot water supplier. Preliminary study was made to give selective absorption power (large short-wave absorption and small long-wave radiation from collector surfaces) to a collector. Deposition of Cu, Ni, Co and Sn oxides as black semiconductors into Al anodic oxidation film porous layers by secondary electrolysis was invalid as well as a painting method. Glossy Ni plating onto Al and black Cr and Ni plating onto the surface more elevated solar exposure surface temperature by more than 20% than black painting. (NEDO)

This report describes the fiscal 1974 research result on glass system materials of plane collectors for solar cooling/heating. A barrel lens type collector was poorer in efficiency than conventional ones. A one-directional Fresnel lens type one was promising for improvement of solar radiation collection. The prototype In{sub 2}O{sub 3} selective transmission cover glass was prepared by vacuum deposition. Although selective characteristics including a solar transmissivity of 74% and an IR reflectance of 75-80% were obtained, further improvement of more than 10% is necessary. The evaluation results of some collectors are as follows. A vacuum type is poor because of its low efficiency and necessary vacuum sealing. A multi-layer type shows unsatisfactory performance at some temperatures. A glass honeycomb type is most likely because of its uppermost collection efficiency, however, development of production technology of heat-resistant honeycombs and its profitability remain to be solved. A deformed multi-layer type is practical because of its high efficiency, simple structure and low cost. Further improvement of the transmissivity and IR reflectance of cover glass by more than 10% is necessary. (NEDO)

Using experimental equipment for materials under the atmosphere of liquid hydrogen, an experiment on mechanical characteristics under the liquid hydrogen atmosphere (20K) was conducted of the base materials of candidate steels (SUS304L, SUS316L and A5083). In material evaluation experiments (tension/fracture toughness/fracture tests), characteristic behaviors of the materials were shown which are different from those shown in the environment of liquid He (4k), etc. Even if the amount of {delta} ferrite in the metal welded of the stainless steel is small, approximately 1%, the degradation of low temperature toughness occurred. Welded joints of stainless steel by submerged arc welding and MAG welding were in now way inferior in tension characteristic to those by TIG welding, but were inferior in toughness ranging from room temperature to extremely low temperature. As to aluminum alloys, materials excellent in extremely-low temperature toughness were able to be found. Under the low temperature hydrogen gas atmosphere, the lower the strain rate is, the higher the hydrogen brittleness susceptibility is around 220K (extremely large hydrogen brittleness temperature) (SUS304L).

The paper described the results of the FY 1999 research on continuous fiber reformed ceramics base composites (CFCC). As reinforced fiber, ZMI grade fiber was used. Polyzirconocarbosilane, raw material of that fiber, as matrices, was dispersed with zircon powder. The composite has remarkably more excellent heat resistance, oxidation resistance, corrosion resistance, and fracture resistance than metal, but so far there are seen no examples of the actual use. One of the causes is the shortage of the database for design of actual parts, especially, of the data on durability under actual environmental loads, and the reduction in reliability by a lack of life estimation technology. Accordingly, the basic experiments were carried out for the elucidation of environmental degradation and for the durability and development of life estimation technology. The experiments were made a step to the promotion of commercialization. As material form, minicomposite was used for unidirectional reinforcement for analytical convenience. Further, as a process to improve the durability of CFCC, minicomposite with glass seal put on was also evaluated. The experiments evaluated the residual strength after basic environmental exposure conditions, and the empirical formula for life estimation was proposed. (NEDO)

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

The following technologies were developed for the purpose of materializing various methods of a solar cooling/heating and hot-water supply system using aluminum and other metallic materials: (1) research on improving corrosion resistance of metallic materials for a heat collector plate and (2) research on a selective absorbing film. The results in fiscal 1979 were as follows. (1) A practicality running test for a solar panel, which started in fiscal 1977, was continuously carried out at eight places in the nation. After approximately two years and a half passed, each panel was cut open and analyzed. As a result, despite a difference in the degree of corrosion by the regions, an Al-Zn-Fe-In alloy had a larger corrosion area than two other alloys, but the corrosion depth was shallower, with the corrosion remained only in the clad layer, which seemed to eliminate the fear that it might grow to be a through-hole for the time being. This research was completed. (2) Research for the selective absorbing film was carried out in fiscal 1979 on a chrome black membrane by a high frequency excited ion plating method and on a carbide and nitride membranes. In addition, a durability test and an Auger analysis were performed for a titanium nitride selective absorbing film that was obtained by a DC bipolar reactive ion plating method. (NEDO)

During ultrafine structure formation due to transformation from austenite to ferrite in an intense magnetic field, the transformation is accelerated by the thermodynamic stabilization of the ferrite phase which is ferromagnetic. The application of an intense magnetic field works effectively during the generation of nuclei. When a magnetic field is applied during reverse transformation, a honeycomb 2-phase structure is formed oriented toward the direction of the magnetic field and, when the structure is vertically compressed, the recrystallized structure is made ultrafine effectively. In pearlite transformation, hardening occurs when carbon atoms supersaturated in density are introduced in the presence of a magnetic field gradient, and curing further promotes precipitation hardening. In a ferrite complex phase system, wherein ultrafine globular cementite is uniformly distributed, plastic instability becomes explicit in a tensile test. There is a good possibility that an ultrafine structure recrystallization model may be built by calculation, into which the distribution of energy stored prior to recrystallizing nucleus formation is incorporated. The profile of a conceptual process of off-line or in-line integration of heavy-strain process and intense magnetic field application has become tangible. (NEDO)

From among researches on hydrogen manufacturing technologies using thermo-chemistry in the Sunshine Project, discussions were given on equipment materials, with the second-stage reaction in the iodine system cycle as the object. This paper describes achievements in fiscal 1979. The reaction produces MgO, I{sub 2} and O{sub 2} from Mg(IO{sub 3}){sub 2}. Corrosion tests were performed by using test pieces made of Ni alloy, iron-Ni-Cr alloy, Ti alloy, Zr alloy, Nb and Ta. These materials are thought to have excellent corrosion resistance in high temperature gaseous phase composed of iodine, oxygen and water. Corrosion tests were carried out also by using sheet formed test pieces of 24 kinds of alloys and six kinds of commercially available non-ferrous metallic materials in different temperatures and atmospheres, mainly the iodine plus oxygen plus H{sub 2}O mixed gas atmosphere at 600 degrees C. The corrosion resistance of the tested materials can be divided into three ranks. Materials having relatively good resistance were Ni-50Cr alloy and Co group alloy. Materials having good corrosion resistance are very little affected by water content. The higher the temperature, the more the metal corrosivity has increased. Preliminary discussions were given on pipe formability in materials having good corrosion resistance as the equipment piping materials. Their mechanical properties were also tested. This paper also describes corrosion resistance tests under heat transferring condition by using pipe-formed test pieces. (NEDO)

Coprecipitation in a chloride-containing water solution is utilized to deposit zirconia nano-particles on alumina particles for the manufacture of a composite powder and a sintered body. As compared with a conventional CIP (cold isostatic press)-molded compact, a slip-cast compact is improved in flexural strength from 1.1 to 1.36Gpa. A composite powder granulating unit is installed. Although it is known that use of the citric acid as gelatinizer in the coprecipitation process results in a homogenous ZrO{sub 2}-Al{sub 2}O{sub 3} composite powder, yet a method is contrived to achieve high crystallinity without gelatinizer by freezing and drying a chloride-containing water solution in a microgravity field. In the near-net molding of spherical ceramic particles, an error in diameter of not more than 50{mu}m is realized. A mass production technology is established by which an inexpensive general-purpose alumina nano-structured material is die-compacted for the manufacture of low-cost ceramic bearings. A high-speed super-flat spherical surface processing technology is developed. In a 25kg-load fatigue test conducted for a combination of nano-structured ceramic balls and steel flat plates that bear the balls, a 240-hour life is attained. The bearing steel stands comparison with those available on the market. (NEDO)

This report summarizes the fiscal 1999 research result on material property test under liquid hydrogen environment, and development of optimum welding material and welding technique for the WE-NET plan. In the study on material properties in a liquid hydrogen temperature range, fatigue strength tests of base metals and weld metals were conducted under liquid hydrogen environment continuously, and further fatigue data were collected. As a result, it was clarified that both SUS304L and SUS316L have extremely high fatigue strength. To improve the tenacity of candidate weld metals under liquid hydrogen environment, material tests of welds were conducted on the laser-welded stainless steel joint and friction stir- welded Al alloy joint prepared by TWI (The Welding Institute) in the U.K. The laser-welded stainless steel joint showed higher low-temperature tenacity and lower ductility than TIG- welded joints. The friction stir-welded Al alloy joint showed extremely improved tensile strength and tenacity in a liquid hydrogen temperature range. For the low-temperature material database, both addition of new data and improvement of software were promoted. (NEDO)

Research has been carried out on various collector members using synthetic resins for a solar cooling/heating and hot-water supply system. In the research on a light selective transmitting film, a technology was established in which an In{sub 2}O{sub 3}/SnO{sub 2} film was processed on a polyester film at a spatter speed of 4,000 (angstrom)/min by using a conventional spattering device and a method of running the film while it was cooled. In the research on transparent heat insulating materials, a plastic heat insulator molding test device was used, molding and evaluating the straight groove type bent molded product of various plastic films, with the best results obtained using a polyester film. The selective absorbing film proved that the synthesizing time of Co{sub 3}O{sub 3} was reduced by about 30% and that no performance was lowered by the mixture of inexpensive metallic oxides, which enabled a prospect of the cost reduction. The base material for the heat collecting body was produced using a three-layer film containing a metallic foil and a water channel of a molded sheet structure by a heat joining method, but no improvement was seen in the pressure resistance. In the general evaluation of the practicality of a high performance collector, the selective transmitting film was found insufficient in the contributing effect to the improvement of heat collecting efficiency. The transparent heat insulating material contributed to the efficiency increase through the improvement of the light transmissivity. (NEDO)

Research and development was carried out for the establishment and commercialization of the technical seeds of a newly proposed 'parallel grinding type aspheric surface grinding method,' based on the results of studies of ultra-accuracy grinding and aspheric surface machining technologies conducted at Tohoku University. The new method is characterized in that a work point on the work piece faces the grinding point on the grindstone cross section on the one-to-one basis because the grinding point travels on the grindstone cross section. Accordingly, the method is quite suitable for corrective grinding for eliminating only the error in case a geometrical error occurs on the wrought surface. For this purpose, measurement of the machine surface on board the machine is indispensable. Hence: a study of corrective grinding methods under an on-board measuring system. As the result, the initially intended geometrical accuracy level was attained in the machining of axis-symmetric aspheric glass lenses and aspheric metal molds, and coarseness on the finished surface in the grinding of glass lenses was reduced to 0.3{mu}m using a diamond grindstone. In conclusion, machining accuracy and finished surface coarseness were remarkably improved, and this enables machining without the need of polishing and demonstrates that there are possibilities of commercialization.

Remaining life assessment technologies for polymeric materials for geothermal power generation and methods for improving their heat resistance are reviewed, and concepts of scale-free technologies for FRP (fiber-reinforced plastic)-sandwiched pipelines for hot water transportation are described. Materials based on PTFE (polytetrafluoroethylene) and NBR (acrylonitrile-butadiene rubber) are chosen for use as DHM (down-hole motor) sealing material and for application to the stator. With PTFE as the matrix, four candidates are prepared, which are additive-free PTFE, and GF/PTFE, GF/CF/PTFE, CF/PTFE, each containing 20w% GF (glass fiber) and/or 20w% CF (carbon fiber). With NBR serving as the matrix, two candidates are prepared, which are NBR-A containing 20w% aramid fiber and NBR-W which is a vulcanized NBR-A. External force, heat, light, and mud are named as the degradation factors, and each factor and some combinations of external force, heat, and light are repeatedly imposed on the materials. During the effort to develop an apparatus for simulating geothermal circumstances in which the factors will affect the materials in complicated ways, a life assessment technique is developed for such polymeric materials. A technology is developed for providing polymeric rubber elastomer with a heat resistant feature. A study is made to replace transportation pipelines for injection wells with FRP sandwiched pipelines. (NEDO)

Targeting at realization of international standardization of a textile material (geotextile) used for interlocking concrete block pavement, R and D has been performed on a performance evaluation method consistent with field works. This paper summarizes the achievements in fiscal 2000. A literature survey has revealed that manuals prepared by the U.S. AASHTO, and ISO related standards show the test method for single geotextile, and guidelines on durability, but the method for evaluating the durability assuming the actual using conditions has not been standardized. The result of a field test reveals definite effects of existence of geotextile on the usability of block pavement in the water permeable bitumen stabilized roadbed, wherein the effectiveness of the geotextile was verified. In the research of an indoor evaluation test method, it was identified that the test method using a roller compactor and a wheel tracking testing machine can reproduce the behavior of block pavement at site, and it is a method that can identify the durability of the geotextile to some extent.

The research involves tests and studies conducted for the evaluation of corrosion resistance of various metallic materials in molten iodine and for the selection of materials to stay usable under iodine-handling conditions. In fiscal 1982, an iodine transportation system is studied, and corrosion tests are conducted for panels of carbon steels, various stainless steels, titanium, niobium, tantalum, etc., of the grade available in the market, under the conditions where the temperature is 113-170 degrees C, I{sub 2} contains 0-10wt% H{sub 2}O, and the gas phase is of N{sub 2}+O{sub 2}. It is made clear as the result that the effect of water present in I{sub 2} is fairly grave while the influence is but a little of the intensity of temperature and the amount of O{sub 2} gas on the corrosion rates of the respective materials, that materials other than niobium and tantalum are not usable as corrosion resistant materials, etc. In a real device, it is recommended that composite materials be used in the form of a liner or the like because both niobium and tantalum are high-cost materials and therefore create economic disadvantages if employed for the construction of pipes, heat exchangers, etc. (NEDO)

In order to ensure international applicability of engineer education such as in universities and other organizations, and to improve the environment to supply human resources demanded by economic societies, a survey was performed on external accreditation systems for engineer education such as in universities and other organizations in the material field. In the survey, discussions were given on whether or not the education program accreditation system for the material field being structured has any problem in the actual operation of the accreditation through trials at Chiba Engineering University and Tokai University. As a result, it was revealed that the criteria are too general, requiring more detailed description on the guideline, and criteria should be so considered that assessment at higher levels can be given to the graduation research, which is a Japan's particular education system. In addition, it was made clear as a problem in the education programming side that a room for improvement remains in the education methods for the engineering ethics, communication skills, and the method for evaluating the students' achievements.

This paper reports the study results on development of composite materials for solar cells under microgravity environment in fiscal 1994. (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 project is aimed at development of the technologies for producing ceramic- and metal-based composite materials, and also technologies for superplastic processing by utilizing the phenomenon of superplasticity. The methods studied for development of the ceramic-based composites include casting and powder-utilizing forming at low temperature, and melt forming at high temperature. Those for the metal-based composites include melting at normal and high pressure, powder metallurgy type mechanical alloying and alkoxide methods. The composites studied for development of the superplastic processing are the whisker- and particle-reinforced ones. The composite reinforced with silicon nitride/SiC whiskers is found to be electrophoretically cast to have a bending strength of 497MPa at 1,250 degrees C. The parts of simple shape, e.g., rod and disk, having the target strength are produced by isostatically pressing at normal temperature and high pressure (CIP) and subsequently firing the granules, produced by spray drying the TiC particle/alumina-based slurry.

A report was made on the 1998 results concerning technological development of super metal. In the 'research and development of super metal', metallurgical examination has been made on crystal grain super refining process using a machining simulator, with studies carried out on crystal grain refining by utilizing large-strain deformation with more than 50% deformation for a single pass and a diploid structure. As a result, it was found that the crystal grain size can be refined to approximately 1{mu}m. Consequently, in fiscal 1998, a high-speed large reduction rolling test equipment was developed capable of rendering a sheathing technology in a mechanically testable size by a rolling method. This test equipment has such capacity as the maximum load of 1,000 ton and the maximum torque of 95 ton/m and is a rolling mill whose scale is largest in the nation on the laboratory level. The rolling speed can be 120mpm, a very fast speed for a large sized rolling mill. Moreover, equipped with an immediate water cooling facility adjacent to the rolls and an automatic operating system for example, it is a high function rolling mill capable of cooling and rolling that render the complex and delicate sheathing technology of super metal.

With an objective of creating ultra-high density organic photo recording elements for photon mode recording and rewritable wavelength multiplex recording by utilizing control of association status of photochromic compound, research and development has been performed. This paper summarizes the achievements in fiscal 1989. In developing the materials, verification was made on effectiveness of the newly structured positive polarity model. The method was used to attempt synthesis of four kinds of new spiropyrane, among which it was discovered that BSP1822 forms J-association complex in the long wavelength region. In the thin film forming technology, the J-association complex of BSP1822 was stabilized successfully in the film mixed with bi-molecular film forming material. In order to develop a technology to form dry photochromic thin films, an organic molecular beam epitaxial device and a thin film structure analyzer were introduced. In the elucidation and research on fundamental properties, discussions were given on properties of the SP1822LB film revealed by the steady-state light and laser pulse light. Furthermore, the molecular orientation of the SP1801 on the air-water interface was investigated, and molecular models on the air-water interface were considered. (NEDO)

This paper describes research on materials of equipment for the second stage reaction in relation with development on a hydrogen manufacturing technology by using the iodine system cycle in the thermo-chemical method. The second stage reaction produces MgO, I{sub 2} and O{sub 2} by decomposition of Mg(IO{sub 3}){sub 2} at 600 to 650 degrees C. Corrosion tests were carried out by using 25Cr-20Ni steel and Ni-50Cr alloy having shown relatively high corrosion resistance in the researches to date, which were added with trace amount of different alloy elements. The tests were performed in gas mixture of I{sub 2}, O{sub 2} and H{sub 2}O at 600 to 700 degrees C for 48 to 192 hours. The average corrosion rate of 25Cr-20Ni steel was reduced by adding Y(0.2%), Ca (0.2%) or Si+Al (1%Si+1%Al), by which relatively uniform corrosion pattern was shown, and the corrosion resistance was improved remarkably. The average corrosion rate of 25Cr-20Ni steel showed a trend of increasing by adding Si and Nb, and non-uniform corrosion like pitting has occurred, revealing that it is not preferable from the aspect of corrosion resistance. The average corrosion rates of the tested materials tended to become somewhat greater under heat insulated condition than under continuously heating condition. Effect of Mg(IO{sub 3}){sub 2} deposition is very small. (NEDO)

As to fiber materials (geotextile) used for block paving, survey/experimental study were carried out with the aim of establishing an evaluation method of the performance which has accordance with the site and of proposing it to international standards. The FY 1999 results were outlined. From the results of the literature survey abroad and in Japan, it was found out that the evaluation method of geotextile as simple substrate had already been standardized, but the evaluation method for durability/separation performance/drainage performance as the block paving system was not standardized. The use of geotextile in block paving is mostly for prevention of outflow of cushion sand, and geotextile is paved in the boundary between sand cushion bed and roadbed. From the survey of durability/properties in IL block paving where geotextile was laid, the useful basic data were obtained. About geotextile, there are correlations between the elongation rate and the tensile strength. It was confirmed that the geotextile laid on granular materials is higher in elongation rate, and it is less in damage than that on the permeable bitumen processed roadbed. (NEDO)

This paper describes the achievements in fiscal 2000 from the development of candidate low-temperature materials for liquid hydrogen transportation and storage (including mother materials and welds) for WE-NET. Evaluation tests were performed on material properties (mechanical properties, low-temperature embrittlement, and hydrogen embrittlement sensitivity) under room temperature and low temperature regions including liquid hydrogen atmosphere. Low temperature toughness of welds was assessed particularly to identify characteristics of different welding methods developed newly for improvements. The stainless steels and the mother materials of aluminum alloy selected as the candidates have sufficient characteristics even under the liquid hydrogen atmosphere, but the welds have lower low-temperature toughness, requiring improvement. For the stainless steels, since the amount of {delta} ferrite in welds affects greatly the low-temperature toughness, adoption of complete austenite type welding metal is effective. The reduced pressure electron beam welding method can enhance drastically the low-temperature toughness of stainless steel. For the aluminum alloy, it can be one of the alternatives to use an alloy system with composition of high low-temperature toughness. The friction stir welding method for the aluminum alloy was found to provide extremely high low-temperature toughness, which can be evaluated as a new welding method. (NEDO)

Summarized herein are the materials designs/production and tests/evaluation results of heat-resistant materials, i.e., alloys, ceramic composites and carbon-based composites, which are expected to be applicable to the hydrogen combustion turbines. These have been studied since 1993, and this paper summarizes the overall evaluation results of the phase I program. The intermetallic compound as one of the candidate materials has a high-temperature strength in a range from 1200 to 1400 degrees C by optimizing elements added. However, no prospect is obtained for heat resistance at 1700 degrees C or more for the material not coated or cooled moderately. Each of the other candidate materials tested shows a bright prospect of applicability at the base material and specimen levels. The single-crystal superalloy for hybrid cooling structures has novelty in that it is free of Cr but incorporated with Si and Hf, showing approximately 10 degrees C higher heat-resistant temperature than CMSX-4. CMC and C/C are inherently excellent heat-resistant materials, and are attractive advanced composites, because they are expected to realize no-cooled blades at 1700 degrees C. (NEDO)

Using an in-situ method, three kinds of Fe-C-Ni-Cr-Mo-Nb-based alloys are developed, whose strength is not less than 800MPa at 1073K. They exhibit, in a high-temperature erosion wear test, a wear resistance which is 2-3 times higher than that of conventional materials. When they are cast, wear-causing graphite precipitation is suppressed thanks to the cast iron coagulating in gaps in the ceramic formed into a net shape. It is also found that in this process the precipitation of cementites etc., which improves on the abrasion and wear characteristics, is accelerated and that the cementites etc. are finely dispersed for improvement on the brake (brake block) characteristics. Tentatively produced brake blocks are tested for performance at the Railway Technical Research Institute. The new materials are found to exhibit a wear resistance which is 2.2 times higher, and a braking capability 1.6 times better, than those of conventional materials. In the case of an Fe-50Cr-4.8C alloy produced by an MA (mechanical alloying) method, {alpha}-Fe is dispersed into M{sub 23}C{sub 6} for a remarkable improvement on the wear-resisting feature. A 10%TiC cermet exhibits a remarkably high wear resistance, that is, a transverse rupture strength of 1270MPa which is higher than that of a cast high-speed steel. (NEDO)

Current technologies are surveyed and tasks to discharge are extracted relating to heat resistant alloys, intermetallic compounds, ceramic based composite materials, and carbon based composite materials, which are expected to be used for hydrogen combustion turbines. Concerning oxide dispersion strengthened alloys for cooled vanes, tasks to discharge are extracted, which relate to the designing, development, and selection of vane materials, bonding layer materials, and coating materials, and to thermal barrier coating techniques and machining techniques. Concerning porous fiber reinforced ceramic materials for ceramic shells, tasks involve the elucidation of corrosion behavior and manufacturing techniques. MoSi{sub 2}, which is a promising high-melting intermetallic compound, also presents some tasks to discharge for an increase in its high strength and high ductility in an ultrahigh-temperature steam/reducing atmosphere, and for improvement in manufacturing techniques. For the carbon/carbon composite material which is the sole material usable in the ultrahigh-temperature domain of 2,000 degrees C, an analysis and evaluation method taking its anisotropy into consideration needs to be developed, and an oxidation resistant coating has to be also developed. In addition to the designing and development of these materials, development is necessary of materials testing and evaluating techniques. (NEDO)

Described herein are the results of the FY1994 research program for analysis and evaluation for thin-film compound semiconductor solar cells. The study on epitaxial growth and optical properties of the thin films of CuInSe2 and CuGaSe2 evaluates the thin epitaxial films grown under various conditions, showing morphology of the defects at the interface of heteroepitaxial growth. These results are used to set the growth conditions under which a thin film of high luminescence by exciter recombination is produced. The study also gives information of luminescence transition in the vicinity of the band ends and of energy level between the bands. The study on structural analysis of the epitaxially grown thin films of CuInSe2 investigates dependence of lattice constants of the MBE-grown CIS layer on film thickness by the X-ray diffractometry based on the bond method. The study on epitaxial growth by the Se(CH3)2-halogen transfer method tests epitaxial growth of the single-crystalline Mo on a substrate of single-crystalline sapphire. 5 figs.

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

This paper reports research achievements in fiscal 1998 for a platform for designing high functional materials. Since coarse-grained models used in molecular dynamics (MD) simulation are diversified depending on materials, phenomena and properties, a general purpose MD engine that can simulate them freely was designed. Methods were developed to determine the potentials of coarse-grained models from the atomistic models. In polymer melts, very slow movements caused by entanglements have a substantially important role, which are difficult to be studied by usual MD simulations. Therefore, fiscal 1998 has devised a coarse-grained model to handle slow movements of straight-chain polymers, and a rheological forecast program was prepared. Studies are also being made on meso-scale structures sufficiently large as compared to atoms and on dynamic property forecast. Works were carried out to develop a simulator, in which polymeric phenomena with large spatio-temporal scale are applied with a continuity model to solve the equation thereof. Improvements were given on the hardware/software environments required for developing simulation engines and platforms for mesoscopic region. (NEDO)

For the purpose of developing high efficient ceramic bearing using nano-structured materials, technical development was proceeded with of raw material powder treatment, forming sintering, processing, structural analysis, property evaluation, etc. As to the study of manufacturing of ceramic balls, the following were conducted by the method developed at Osaka Prefectural Institute of Industrial Technology: coprecipitation laminate processing of ZrO2-Al2O3 system to alumina powder at Okumura Crucible Mfg. Co. Ltd., spherial press processing and sintering at Kyocera Co. Ltd., and precise machining at Nippon Pillow Block Mfg., Co. Ltd. The performance as bearing was measured of the ceramic balls obtained such as surface coarseness, sphericity, crush strength and fatigue life. Surface coarseness and sphericity were the same as those of bearing use silicon nitride, but crush strength was considerably low. In the experiment on rolling fatigue strength as bearing, separation occurred within 100 hours even at a load of 100kgf. It is thought that this is because of the pores remaining on the surface, and the measures to be taken for long life were studied. 12 refs., 64 figs., 27 tabs.

With the purpose of developing high strength and high-anticorrosive aluminum-based material through microstructure control, R and D was conducted, with fiscal 2000 results compiled. In the research of grain refinement mechanism, molten metal rolled stock was experimentally produced in which Mg content was varied 0-2.5 mass % with Al-2.5 mass % Mn as its base. As a result, a microstructure with an average grain size of about 3 {mu}m was obtained by processing the alloy through homogenization at 550 degrees C, cold rolling by 91% and the final treatment at 350 degrees C without Mg addition. Addition of Mg increased square grain boundaries in the microstructure, raising proof stress to about 180 MPa in Al-2.5%Mn-2.5%Mg alloy. In the research of development of the machining process, a rapid heating process was performed on a typical aluminum alloy, with the effect examined, by an alloy system or a plate thickness, on the electric power used and on the temperature reached. A rapidly heated aluminum alloy plate turned to have a microstructure with equi-axed grains of a uniform size, compared with a salt bath processed material heated at the same temperature. (NEDO)

Study was made on the applicability of mechanical milling (MM) and mechanical alloying (MA) to Fe system alloys. Metastable austenitic stainless steels such as SUS316L and SUS304L form {alpha} phases by strain induced transformation due to MM, and are subjected to further plastic deformation. Nano-size fine structure was obtained through inverse transformation into austenite({gamma}) by heat treatment or high-temperature sintering of MM powder. Fine microduplex structure of 620nm in average crystal grain size was obtained for SUS316L. This material showed nearly 3.3 times higher 0.2% tensile proof stress, nearly 1.8 times higher tensile strength, and 35% higher elongation than conventional ingot steels. Solid solution powder of 12Cr-Mo-W ferritic steel was sintered by hot isostatic pressing (HIP) under low- temperature and ultrahigh-pressure conditions of 650degC and 588MPa. The as-HIP`ed sample and sample annealed at 800degC showed average {alpha} grain sizes of 33 and 50nm, respectively, and a strength twice as high as that of 12Cr steel. 97 refs., 60 figs., 18 tabs.

The paper described the results of the survey of the nonferrous metal field relating to the FY 1999 long-term energy technology strategy. The needs for electronics products are increasing toward the 21st century. Domestically the competition with other countries in enlarging the market share has been intensifying. At the same time, the smaller the size of device becomes, the more the barriers in technology to be overcome increase. In the development of Si wafer to cope with such a situation, there are a lot of problems to be broken down in liaison with industry/government/university. Compound semiconductors are higher in speed than Si, and have a marked feature of producing light, but are difficult in crystal growth. It was in the past 20 years that the development of commercialization technology has rapidly advanced. Compound semiconductors are indispensable as a device in the energy problem which strongly influences the global environment. In the U.S., for the military use, a policy for upbringing national industries has been carried out since 1993. The role of compound semiconductor materials playing as the fundamental industry which supports the semiconductor industry and system industry as the nation's core industries is important even in Japan the same as in the U.S. (NEDO)

Efforts were made to develop methods for evaluating the characteristics of metallic materials experiencing high-speed deformation or impact deformation. The research was conducted by the research WG (working group) consisting of some participants of an international conference convened this fiscal year. The research result revealed that studies in Japan lopsidedly dealt with metallic materials at strain velocity of 10{sup 4}/second or less, such as steel, while many studies overseas dealt with materials other than metals at strain velocity over 10{sup 4}/second. The test and evaluation WG conducted high-speed tension tests for T6-treated aluminum alloys using the split Hopkinson bar method, hydraulic servo method, one bar method, and the sensing-plate method for measuring force, and the results were compared. It was then found that the one bar method produced disturbance more remarkably than the others and that the loading block structure and load rise time influenced the emergence of the peak load. The emergence of a peak load in the Hopkinson bar method or the one bar method had been predicted on the basis of the research conducted by the analysis group. (NEDO)

The present state and trend are surveyed of organic ferroelectric thin films, new carbon materials, fullerene compounds, and thermophotovoltaic (TPV) power. In the study of organic ferroelectric thin-film solar cells, the effort still remains at the basic stage, with the conversion rate as low as 3% in Europe and 2% in Japan. The progress of basic studies, however, is worth attention. It is deemed that 15% is the photoconversion rate to be currently expected from new carbon material solar cells. Fullerene compounds include some semiconductors whose bandgap values may be controlled across a 0.75-1.95eV range, and they may find their place in thin-film solar cells. However, their physical properties are not fully known, and their development into devices such as solar cells is scarcely reported. The research and development of TPV in the U.S. is led by NASA (National Aeronautics and Space Administration) and NREL (National Renewable Energy Laboratory), with their efforts concentrated on the development of portable power sources utilizing combustion heat. In Europe, TPV application to small-scale residential cogeneration systems is under study. (NEDO)

Researches have been made to increase density of 200,000-kW class generator and to increase capacity of 600,000-kW class generator necessary for putting superconducting generator into practical use. This paper summarizes the achievements in fiscal 2000. In the study of increasing densities of superconductors and field windings, strands were fabricated, in which aging heat treatment conditions, number of aging, and processing degrees between each aging were varied, to increase the critical current of Nb-Ti strand, wherein as high critical current as corresponding to about 90% of the target was obtained. Possibility of increasing the critical current with the final processing degree in the range of 4 to 5 was verified from the relationship between the final processing degree and the critical current. In the study of increasing capacities of superconductors and field windings, findings were acquired on enhancement of conductor stability and reduction in AC loss, with regard to superconductor strands well balanced in the two elements. Prospects were obtained in achieving the AC loss of 200 kW/m{sup 3} in the targeted superconductor. The residual resistance ratio was found to be 200, showing sufficiently high value, and sufficient function was verified in the stabilized copper. In the research of design technologies, primary basic design was performed. (NEDO)

A survey is conducted of wet-type solar cells that may constitute an important field in solar chemistry. The wet type solar cell made known by Graetzel et al. in 1991 is a combination of ultrafine TiO{sub 2} grains and a sensitizing dye. The ultrafine grain surface structure enlarges the area of an electrode for the absorption of 46% of incident solar radiation of which 80% or more is converted into electric power. The fill factor at 520nm of a cell fabricated for an additional test turns out to be 40% against the 76% mentioned in technical literature, and the conversion efficiency 10%. The Titanyl sulfate is also tested because it is low in price as material for titanium oxide. Functional groups are experimentally introduced for the generation of bonds on the substrate to be effective in the injection of a sensitizing dye. A sensitizing dye with two carboxyl groups and two bipyridine rings as ligand is allowed to be supported by TiO{sub 2}. IR (infrared) spectrometry is performed, and then formation is found of ester-like bonds or chelate bonds due to the interaction of carboxyl groups and the substrate surface. This is enhanced by surface treatment. (NEDO)

The paper described the results of the survey of the nonferrous metal field relating to the FY 1999 long-term energy technology strategy. The needs for electronics products are increasing toward the 21st century. Domestically the competition with other countries in enlarging the market share has been intensifying. At the same time, the smaller the size of device becomes, the more the barriers in technology to be overcome increase. In the development of Si wafer to cope with such a situation, there are a lot of problems to be broken down in liaison with industry/government/university. Compound semiconductors are higher in speed than Si, and have a marked feature of producing light, but are difficult in crystal growth. It was in the past 20 years that the development of commercialization technology has rapidly advanced. Compound semiconductors are indispensable as a device in the energy problem which strongly influences the global environment. In the U.S., for the military use, a policy for upbringing national industries has been carried out since 1993. The role of compound semiconductor materials playing as the fundamental industry which supports the semiconductor industry and system industry as the nation's core industries is important even in Japan the same as in the U.S. (NEDO)

Described herein are the results of the FY1994 research program for analysis and evaluation for thin film solar cells. The study on quantitative analysis of hydrogen atoms in a plasma determines quantity of hydrogen atoms in the plasma of monosilane diluted with hydrogen. It is found, contrary to expectation, that quantity of hydrogen atoms in the plasma decreases as it is more diluted with hydrogen. The study on light-induced degradation of the thin chlorine-base amorphous silicon films confirms that the plasma CVD method with 20% of dichlorosilane gas added to monosilane gas produces the thin amorphous silicon film 3 times faster than the conventional method. The thin film has essentially the same defect density as the one prepared by the conventional method, showing good photoelectric characteristics. The thin film of chlorinated amorphous silicon has a 1 digit lower defect density than the conventional one of amorphous silicon, as revealed by the accelerated degradation test with irradiated laser light and the constant current method to determine saturated defect density. 3 figs.

The above-named studies aim at enhancing the practical application of gasification fusion furnaces designed to burn at high temperatures for the prevention of dioxin emissions. In the basic study for the development of high-temperature corrosion resistant refractories, it is found that cromia, picrochromite, zirconia, and some others are highly resistant to fused slag of refuse and that chromia is the best among them. As for non-chromia based materials, it is found that they turn equivalent in terms of corrosion resistance to chromia based materials when silica based minerals are added to them. In the effort to develop chromia based new fire resistant materials, some which are excellent in corrosion resistance are obtained out of materials based on MgO-Cr{sub 2}O{sub 3} or Al{sub 2}O{sub 3}-Cr{sub 2}O{sub 3}. In the study of developing fused slag into resources, it is learned that there is feasibility of using heat treated mixtures of slag and waste glass as a material for pavement, as a material for ordinary building bricks, and as a substitute of sand for concrete.

The paper described the results of the survey of the fine ceramics technology field relating to the FY 1999 long-term energy technology strategy. The fine ceramics industry is a new industry for which the future development is expected. It has far-reaching effects on other industries. Japan has the advantage over other countries. As subjects to remarkably develop the industry, needed are the long-term basic preparation which promotes technology innovation such as the promotion of the fundamental/creative R and D, construction of an industry/university liaison system, and arrangement of the intellectual base. Preparation of the competitive environment and promotion of policies paying attention to the market are needed which make the development under the private control by creative study/corporate activities possible. Also important are the demonstration of leadership and secure international competitive force in the light of Japan's international position. For the private-control development, the role and course of various groups should be made clear from a long-term aspect. It is desirable that university/government will newly develop innovative technology, and industry will make the present technology force more developmental and competitive. Support from the nation is requested for researches large in scale. (NEDO)

Attention is paid to behavior at the molecular level with reference taken to the photosynthetic mechanism, and a behavioral mechanism is proposed, which incorporates, in place of the conventional band model, a concept of a molecular structure based on electron transfer, excitation energy transfer, and reactions of oxidation and reduction. Discussion is then made on elements of technology development for the embodiment of high-efficiency organic ferroelectric thin-film solar cells. The elements taken up include the feasibility of organic ferroelectric thin-film cells, photoelctric conversion systems of plants and photosynthetic bacteria, solar cells using donor-acceptor type dyes, organic thin-film solar cells using conductive polymers, and efficient photoexcitation of organic dyes. Fullerene compounds are semiconductive and their band gaps may be controlled to stay within the range of 0.75-1.9eV, and this justifies a hope that they will serve as solar cells. As for TPV (thermophotovoltaic) conversion, it is under development mainly at NASA (National Aeronautics and Space Administration) as a transportable power source based on heat of combustion. Efforts are also being exerted since 1990 in five European countries to develop TPV systems for small-scale cogeneration. (NEDO)

Studies centered about a method for evaluating coarse pores and coarse grains in sintered bodies, relations between sintered body fracture strength and textural structure, and the standardization of evaluation methods. As the result, an evaluation method for observing pore structures in a sintered body flake specimen under an optical microscope and another for observing coarse grains under a polarization microscope were proposed. As for the effect of coarse defects on the fracture strength of ceramics, it was demonstrated experimentally and theoretically that coarse defects several tens of micrometers in size greatly affected the fracture strength. In the study of methods for sintered body grain size evaluation, findings were obtained about the processing of the specimen surface. (NEDO)

The development was proceeded with of electromagnetic wave absorbing materials (board) which dispersed carbon fiber as conducting material and ferrite as magnetic material to matrices such as resin and cement. With the multi-layer structure as a basis, the material has wave absorbing ability in the area of 300MHz-60GHz band. The material is presumed to be applied to wall construction use materials and bodies of electronic equipment since it prevents the radio wave reflection caused by structures such as bridges. Ferrite was synthesized by microwave-hydrothermal method (500kPa, 2.54GHz). Further, carbon fiber was covered with ferrite for improvement of absorption characteristics. Studies were made in the following 5 fields: 1) design of smart materials and development of hybrid process technology; 2) study on the evaluation of wave absorbing function; 3) R and D of the manufacturing process of smart forming materials; 4) development of the fiber surface processing process using ocean resource; 5) comprehensive investigational study. In 1), study was conducted on relations among electromagnetic shielding characteristics of the ferrite-covering carbon fiber, fiber length and fiber content. (NEDO)
