    For the purpose of establishing the basement technology relating to photoreactive materials which make remarkably higher density and larger capacity of the information recording possible, the following were made for photochromic materials and PHB materials: elucidation of the photoreaction mechanism, development of materials, development of material processing/structure technology and development of evaluation technology. The target is to establish the technology of the multiplex recording which is applicable to the super-high density recording in relation to PHB materials/organic photochromic materials which have potentiality of photon-mode recording. PHB materials were developed which have potentiality of 600 wavelength multiple recording and 5 electric field multiple recording in 4.2K and 9 wavelength multiple recording in 77K. Photochromic materials were developed which have high sensitivity and preservation stability and have potentiality of 10 wavelength multiple recording at room temperature. A new photo-recording method was found out by which the orientation of liquid crystal is photo-controlled and potentiality of the multiple polarization was shown. Moreover, the fabrication was successfully made of PHB materials and photochromic materials which make non-destructive readout operation of more than 10{sup 4} times possible. (NEDO)

    This project is aimed at establishment of the basic technologies for photo-reactive materials capable of, e.g., superhigh-density, superhigh-resolution display using photo-functions to control structures and associated conditions of the molecules. More concretely, the efforts are directed to realization of the technologies for multiplexing, sensitivity-response and material stability, applicable to superhigh-density recording by photochromic and photo-chemical burning (PHB) materials. For the photochromic materials, the long-chain alkyl derivatives of photochromic compounds, e.g., spiropyran and fulgide, are formed into thin films by the LB method, in order to develop organic, superhigh-density recording devices by controlling their associated conditions, and controlling of the photochromism reactions in the films is studied. Those studied for the PHB materials include improvement of heat resistance of the materials, development of quinone-based materials and improvement of their degree of multiplexing, and development of porphyrin-based materials and of technologies for structuring them. The comprehensive survey/research activities include extraction of the problems involved in the themes mainly related to the committee activities, and related technologies. (NEDO)

    With an objective of putting into practical use the wavelength multiplex recording system applied with the PHB phenomenon, research and development has been performed on material systems making high quality hole production possible at high sensitivity and high density. This paper summarizes the achievements in fiscal 1989. In the discussion of PHB materials, measurements were performed on the triple state of zinc, magnesium, copper and iron complexes of tetra-phenyl porphin and the triple state spectra by using the flash decomposition method in order to develop new photo-gate type material systems. Correlation was discovered between the free energy change in the reaction and the PHB reactivity from the result of the experiments, whereas important findings were obtained for designing the photo-gate type PHB material systems. In the discussion of the wavelength multiplex recording, an optical system was designed and fabricated to perform scanning and detection on sample surface by using laser beam squeezed to a diameter of 100 {mu} m. Discussions were given on the wavelength multiplex recording, position multiplex recording, and high-speed recording using this optical system. As a result, position multiplex holes were produced successfully by using the laser beam squeezed to a diameter of 100 {mu} m on four different positions on the sample surface, when the tetra phenylporphin derivative was used.

    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)

Stability of holes in the tetra-alkyl pyridinium porhpn/polymer system was evaluated, the hole half-width was measured accurately by using ring die laser, and the hole forming characteristics were evaluated by means of high-power density and brief laser light irradiation. In search of new guests, a two-photon absorption spectrum measuring instrument was assembled to measure samples having zinc tetra-phenylporphyrin derivative as the guest. In addition, hole formation was discovered in samples having indomethylene based coloring matter as the guest. (NEDO)

    Evaluations were given on spatial resolution and measurement time of an optical tomographic system by using the developed 64-channel time-resolved spectroscopy and an image reconstruction algorithm. With respect to the spatial resolution, the target value of 1 cm was verified from tomographic images of a phantom with a diameter of 10cm, simulating a neonate. The measurement time achieved 20 minutes, being one third of the target value. In installing the equipment at Hokkaido University, speeds of the optical switches and attenuators were increased to have reduced the measurement time to one minute. For installation at Kanagawa Rehabilitation Center, development has been made on a nano-second light pulser, whose average beam quantity has been increased to 40 times, and improvement has been given on the optical switches, the attenuators, and the indication software, by which the measurement time was decreased further by 30 seconds than that at Hokkaido University. In performing the clinical evaluation, the evaluation protocol resolved by the Experiment Evaluation Special Committee was submitted for deliberation at the Medical Welfare Device Clinical Evaluation Committee. Upon having been authorized by the Committee, the clinical evaluations were performed at Hokkaido University and the Kanagawa Rehabilitation Center. (NEDO)

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

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

    The necessary technology realizing Terabit class optical network is the signal multiplexing both in temporal and spectral domains. Controllability of ultrafast optoelectronic systems is therefore the priority issue. Specifically we chose semiconductor lasers as the key devices. The methodology for performance improvement and the creation of novel functionality are investigated. Firstly compression of semiconductor laser pulse reached the world record of 65 femto second. Secondly a proposal was made to control mode locked semiconductor lasers via subharmonic synchronization and a substantial phase noise reduction was demonstrated. Thirdly a new technology was developed to realize broadband anti-reflection coating on semiconductor laser amplifier facet, bringing about significant performance improvement. To compensate the dispersion induced signal distortion a broadband semiconductor laser amplifier four wave mixing was analyzed and also demonstrated experimentally. (NEDO)

    For expanding the optical diagnosis to clinical medicine, we tried to use the several optical characteristics of living tissues in addition to absorption measurements of blood. The scattering and luminescence of the tissue were examined in detail. The final goal of the research is to introduce the contrast agent active in the near-infrared region. (1) We have succeeded in obtaining the scattering and absorption coefficients separately from the time-resolved data of living tissues such as rat head and even human head. Then, based on the basic equations derived from our experiments, the quantification of the absolute absorbance was performed. (2) Using the near-infrared fluorescent dye, Rhodanine 800, we could monitor the energy state of tissues. We concluded that Rhodamine 800 is the possible candidate for energy-reporting contrast agent applicable to near-infrared spectrophatometry. (NEDO)

    Full Text Available In this article we will interrogate the notion of ‘the unacceptable’ by tracing the movement of a particular text – a series of manga novels by Keiko Tobe entitled Hikari to tomo ni (With the Light: Raising an Autistic Child, 2001-2010 – from serialisation in a Japanese women’s magazine, to publication in Japanese as a series of manga novels, to publication in English in book form. In following this text – a narrative of parenting a child with autism from birth to adolescence - through its various contexts of production and reception, we want to raise doubts about a shibboleth of a particular kind of media and cultural studies - that the unacceptability of a text in mainstream popular or political contexts makes it particularly interesting from a scholarly point of view. Our account of Hikari to tomo ni’s movement through its various contexts of publication and reception supports Mitchell and Snyder’s argument that disability politics does not allow easy categorization of representations into ‘straightforward catalogues of “acceptable” and “unacceptable”’ (Mitchell and Snyder, 2001, 213. The context of the original publication of the serial in Japan demonstrates the barriers to publication of manga centring on experiences of disablement. Such stories were seen as commercially unacceptable not only because they seemed difficult to market as entertainment, but also because they required the use of contested language which might draw unprofitable attention. Tobe’s work and its enthusiastic reception by the readers of For Mrs. ultimately overcame publishers’ qualms. Yet the visual strategies adopted by Hikari to tomo ni and the reception of this manga in an English language context demonstrate the way its writer and publishers manage its apparently unacceptable theme.

    Research and evaluation was performed with an objective of establishing the basic technology related to light-reactive materials that control the structures and status of aggregation of molecules by using actions of light, and can be used for ultra-high density recording, high resolution indication and light switches. In elucidating the basic characteristics of photochromic materials, a non-destructively readable recording system was proposed and demonstrated, highly durable and high-functional photochromic compounds were developed, and a number of material design guidelines were accumulated to realize characteristics required in light-beam recording. With regard to development of the photochromic materials, realization of photochromic thin films that can record wavelengths in multiplex manner has become more realistic. For elucidating basic characteristics of PHB materials, a method for evaluation from a number of directions including the time method for photon echo was established in addition to the conventional frequency recording characteristics. Regarding the elucidation of the PHB phenomenon, demonstration was carried out on intermediate zone structure control in diversified material systems including living organism substances, where a large number of findings were accumulated.

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

    With the purpose of converting solar heat energy to an industrial heat energy, an examination was carried out empirically on the case of using a heteropoly-acid photo catalyst for the decomposition reaction process of 2-propanol. The experiment was performed in Florida Solar Energy Center, in the U.S.A.. The device for the experiment was constituted of a reaction part, distribution manifold for feeding from the lower part of the reaction part a 2-propanol solution for which a photo catalyst was suspended, storage tank served also as a gas-liquid separating container, and circulating pump. Silica-tangstic acid was used as the photo catalyst. In an outdoor experiment using solar radiation, the quantity of inclined global solar radiation was 530-950W/m{sup 2} in clear days and 100-600W/m{sup 2} in cloudy days, with temperatures between 17 and 26{degree}C throughout the experiment period. In addition, an indoor experiment was also conducted using an artificial light source (UV light). As a result of the experiment, the energy conversion efficiency was at most about 1% of incident UV light, a low figure compared to a heat utilization ratio of approximately 15% with a thermal catalyst. 6 refs., 8 figs.

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

    Medical application of lasers is rapidly expanding in accordance with the development of laser technology. However, it is difficult to predict how light propagates and is absorbed by living bodies because of strong scattering of light by biological tissues. Therefore, the determination of light dose has been based on experience. This fundamental study aims to develop a imaging simulator which can predict propagation of light and its effectiveness in medical diagnostics and therapeutics. Teoretical models of light propagation in biological tissues have been constructed, and experiments have been conducted to validate the theoretical calculation. In the theoretical calculation, a three-dimensional model which simulates a human head with five layers of different tissue types. Numerical calculation has been done by using the finite element method to simulate the propagation of ultrashort pulse light, and it is shown by a computer graphics technique for the first time in the world. In the experiment, a solid phantom which anatomically and optically simulates a human head based on MRI images has been fabricated by using the optical prototyping technology for the first time in the world again. Also, we have compared the experimental results of the transmitted light through the solid phantoms with the theoretical results and have succeeded in reconstructing the tomographic images of optical properties.

    Processes that contain latent environmental problems are the massive generation of wastes (inorganic salt, acid catalyst, base catalyst, and huge quantities of wastewater), handling of dangerous substances (use of hydrogen fluoride, use of phosgene, and use of substances whose discharge is legally controlled), processes which consume much energy (circulation of quantities of raw materials, use of quantities of solvents, separation of products with difficulties, use of high pressure, and multiple stage reaction), and processes which are expected to use resources now remaining unexploited. As an element technology for the solution of problems, there is the development of a solid redox catalyst for liquid phase oxidation. As compared with a liquid phase homogeneous catalyst, it discharges less inorganic wastes, facilitates the separation, recovery, and treatment of inorganic salts, corrodes structural materials less, and is thermally stable. An alkane partial oxidation catalyst when developed will achieve more energy conservation than an alkene oxidation catalyst. In relation to acid/base reaction, the zeolite catalyst will be improved and ultrastrong acids and ultrastrong bases will be developed, and these will reduce wastes, mitigate corrosion, and facilitate product separation. The development of a process is also expected which will avoid the use of toxic phosgene. (NEDO)

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

    Experiments were conducted on laser-aided decomposition and removal of chemical substances in liquid phase systems on the assumption that there existed chemical pollutants in wastewater or water after washing burned ash. The aim of the research was to split carbon-chlorine bonds and break benzene rings, the two being the cause of harmfulness, and experiments were conducted using chlorophenol. The photolytic lasers were ArF excimer laser and KrF excimer laser. It was found that the reduction rate of chlorophenol in a water solution under excimer laser irradiation was 1.7 times higher under KrF laser than under ArF laser. For mediums other than water, isopropanol was used, more convenient than chlorophenol in separating organic pollutants from burned ash and the like. In this case, organochlorine compounds were generated at the beginning, but they disappeared when irradiation was prolonged. It was demonstrated that the laser-aided environmental cleaning technology would find a very wide scope of application as an effective photolytic means. (NEDO)

    With an objective to develop a high-speed high-density light beam recording technology by application of proximity field light, researches were performed on a flat opening type proximity field head, a recording and replaying system for the super lens, the materials thereof, proximity field optical elements, and the application to lithography. As a result of the researches, development was made on a promising light scattering super lens, whose noise level is low and the carrier is stable. Deterioration of the replay signals in association with repeated read-out is caused by instability of the recording film. It was verified, however, that more than 60,000 read-outs are possible by adding oxygen into the recording film material to raise the crystallization temperature. Application of the super lens to organic thin film recording utilizing thermo-chromism was verified to be effective. In discussing the application of the super lens to lithography, a possibility was confirmed to expose a resist film through the super lens structure. A simulation program for the proximity field light was developed, and new findings were acquired. (NEDO)

    Emphasis was placed on the research on a planar apertured near-field head and a super-RENS (super-resolution near-field structure) method, as a near-field application element for replacing protruding probes, which has a number of difficult points in developing near-field recording into a practical system, and as a recording and reproducing method. The super-RENS method, as a result of the examination, has become capable of recording/detecting a mark of the minimum 60nm diameter, by the near-field, under conditions such as the most advanced optical disk size and the number of revolution of the disk. This means that a high density recording is possible which is at least 40 times as dense as a DVD (digital versatile disk). It was confirmed by an experiment that the high density was possible in the track pitch direction by the super-RENS method. As a result of the examination on the behavior of the near-field in the super-RENS disk, it revealed that signal detection by the transmitted light which had not been tried before was effective for the improvement of the performance. The smallest detectable mark size was 80nm, in which case CNR (carrier to noise ratio) was 6.4dB. These values are approximately the same level as in the signal detection by reflected light, and are insufficient to verify the superiority. (NEDO)

    With an objective of realizing super large capacity recording technologies largely exceeding the current limits of optical recording and magnetic recording, studies were conducted on application of near-field optics. In the study on recording by using near-field light, it was verified that a mark with approximately the same size as an aperture diameter can be formed on a phase change recording film when a fiber probe with an aperture diameter of about 200 nm is used. However, it was found that the recording using this system takes excessive amount of time. When laser light collected on an objective lens was irradiated pulse-wise, a mark with a minimum width of about 20 nm was observed with high contrast. This will mean that a record with recording density of one terabit/in {sup 2} can be read out. Other studies performed include those on evaluation of effects of polarized light and surface shape on near-field read-out, simulation, mechanism of crystallization in a phase change recording film, recording and playback with ultra-high resolution by using a conformable near-field aperture, fabrication of a flat aperture type near-field light probe array, and the evaluation thereon. 22 refs., 27 figs.

    Research was made on improvement of the wettability and boiling heat transfer characteristics of a photocatalyst wall. Measurement experiment of the wettability was made for anatase type titan oxide-coated Al, SUS and Pb plates, rutil type titan oxide-flame coated SUS plate, raw plate, and oxide-plasma coated titan plate. In the ground experiment, the contact angles of distilled water and oil on specimen surfaces were measured. In the microgravity experiment, falling droplet images were recorded by using the facility of Japan Microgravity Center (JAMIC). For obtaining the effect of radioactive emission, UV irradiation, {gamma} ray and neutron beam irradiation by nuclear reactor, and {gamma} ray irradiation by Co-60 were carried out. As the experiment result, the rutil type titan oxide-flame coated SUS plate, nonconductor-coated titan plate, and zircaloy plate showed large improvement of the wettability by {gamma} ray irradiation with Co-60. It was also confirmed that in particular, titan shows the large effect of radioactive emission, and the wettability deteriorates rapidly after {gamma} ray irradiation. (NEDO)

    The research aims to develop materials and apparatuses for the purification of atmosphere using titanium dioxide that exhibits a powerful oxidizing capability when irradiated with light. A study is conducted to find out an optimum composition for a photocatalytic fluorocarbon polymer sheet suitable for use in a denitration apparatus. A high density fluorocarbon polymer sheet composed of TiO{sub 2} modified with 0.3% of Pd/absorbent zeolite/fluorocarbon polymer PTFE (polytetrafluoroethylene) =48-63/24-36/10-20 is found to show high denitration efficiency, and this achieves the denitration efficiency goal. As for sheet thickness, 0.75mm is found to be enough. The sheet experiences some hardening in an accelerated exposure test, but does not change much in a surface gloss test or a chalking test. Although a slight reduction is observed in denitration efficiency, yet the durability goal is achieved. In the effort to develop an energy conservation type air cleaning apparatus, field tests and experiments are repeatedly conducted. As for photodenitration in the cleaning apparatus, the number of photodenitration stages and the magnitude of equimolar adsorption area necessary for achieving an 80% denitration rate is calculated from the relations of the NOx concentration profile and the denitration rate in the equimolar adsorption module to (gas flow rate/module surface), and the result shows that the initially intended goal is achieved.

    The study items for the current fiscal year are as follows: (1) fundamental studies on coal liquefying reactions, (2) studies on product reforming, and (3) studies on product utilization. In Item 1, investigations were given on effects of hydrogenation treatment for a heavy circulation solvent in the coal liquefying reactions imposed on yield and nature of the product oil. Liquefying reactions were carried out under the presence of various heavy solvents having different hydrogen donating performances, or iron-based and oil soluble solvents. Liquefaction rates, yields and natures of different products were analyzed to discuss the degree of hydrogen donating performance of the solvents, the using conditions for the catalysts in the primary liquefying reaction, and the reaction conditions to enhance the product oil yield. In Item 2, hydrogenation treatment was given on the heavy oil fraction of the product oil obtained from the liquefying reaction using a heavy circulating solvent. The result was compared with the result on the medium oil fraction. Light oil fraction obtained from brown coal liquefaction was reformed to manufacture the reformed oil for engine tests. In Item 3, nature analysis and combustion tests were performed on the light oil fraction of the liquefied oil using brown coal as the material, and on the hydrogenated oil as a diesel engine fuel. The reforming effects were discussed from the amount and nature of the exhaust gas. (NEDO)

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

    This paper describes the achievements in the Sunshine Project in fiscal 1990 on research of coal liquefying reaction. The research contributes to developing a coal liquefaction technology as one of the methods for manufacturing clean energy and chemical raw materials from coal. In the fundamental study on the liquefaction, primarily liquefied heavy constituents in different types of coals were divided into such constituents as HI, TI, and THFI to discuss the performance and coking behavior of each constituent as solvent. Furthermore, effects of hydrogenation treatment were also elucidated. Decomposing reaction was performed on different heavy products to discuss effects of the reaction conditions. In the liquefying reaction using petroleum-based heavy oil as solvent, different shale oils were used in experiments for comparison with the case of using tar sand bitumen. In the study of reforming the product, comparison was carried out on reactions in hydrogenation treatment and contact decomposition of medium to heavy fractions of liquefied oil. A separation experiment was made on hetero compounds by means of solvent extraction and pressure crystallization of liquefied oil naphtha and light oil fraction. Effects of additive were investigated in an engine test on the stabilized and balanced light oil fraction. Discussions were given on high level utilization of heat treated oil recovered from residues in liquefaction distillation. (NEDO)

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

    Upon the development into a single law of the three liquefaction related laws, studies are started on coal liquefaction reaction and the reforming and utilization of the products. In the research on coal liquefaction reaction, the solvent ratio, change in reaction time, and change in liquefaction product constitution in case of repeated circulation of the solvent are tracked, and their relations with the liquefaction rate and yield are studied, these efforts involving the Taiheiyo coal, Yallourn coal, and the Miike coal. The Taiheiyo coal is subjected to a short-duration liquefaction reaction test. In the research on product reforming, the medium-gravity fraction from coal liquefaction is subjected to hydrogenation, and the effect of the reaction conditions on the properties and constitution of the thus-treated oil are studied. An SRC (solvent refined coal) solution of the Taiheiyo coal is subjected to hydrogenation in the presence of a Ni-Mo catalyst, and the SRC cracking rate and product properties are compared with those obtained from another solution treated with a Co-Mo catalyst. In the research on product utilization, the medium-gravity fraction from coal liquefaction is subjected to hydrogenation under three sets of different reaction conditions in the presence of a Ni-Mo/Al{sub 2}O{sub 3} based catalyst. In this process, specimens are prepared by mixing the original oil, its hydrogenated product, and a petroleum-based light oil, and a study is made about the usability of the specimens and their mixtures with petroleum-based heater oil as light oil or heater oil.

    This paper describes the achievements in the Sunshine Project in fiscal 1992 in studies on liquefying reaction in coal, and reforming of the products. High conversion rate was attained in the co-treatment of bitumen and Taiheiyo coals by using highly dispersing oil soluble solvent without performing coking, even if the asphaltene concentration is high. When a very highly acidic trifluoromethane sulfonic acid catalyst is used, hydrogenation and conversion to solubilized low molecules is possible even with a solvent having low affinity with coal. Swelling effect by tetralin is remarkable in pulverized coal, and the conversion rate was improved greatly under high-pressure hydrogen. When naphtha of the Wandoan coal liquefied oil is given extraction treatment with base and acid/base, the gas production decreases noticeably when hydrogenating and refining the extracts, resulting in reduced hydrogen consumption and improved oil recovery rate. Furthermore, when the extraction treated naphtha is hydrogenated, denitrification can be achieved completely. Kerosene and light oil liquefied from the Wandoan coal were cracked by fluidity contact, whereas the light gravity product yield due to the decomposition was found low because of containing a great amount of two-ring aromatics. The pressure crystal deposition method using solvent is effective in separation of high-melting point compounds including anthracene from heavy gravity oil. (NEDO)

    The R and D project has been implemented for developing the thin film-making process techniques which can increase areas of titanium oxide (TiO{sub 2}) photocatalysts sensitive to visible light and their mass production. The fundamental investigations are directed to elucidation of the mechanisms involved in manifestation of activity in visible light of the visible light-sensitive thin film doped with the Cr, V or other ions. The sputtering involving no ion implantation is devised for producing the thin films, to realize the highest visible light sensitivity recorded for the thin TiO{sub 2} film. The sputtering process is investigated in detail for the film-making conditions, e.g., Ar pressure, effects of coexisting O{sub 2} gas, and power gap. The conditions under which the thin film serviceable under commercial conditions can be produced are not established yet, but it is confirmed that the coating film shows superhydrophilicity and photocatalytic activity for, e.g., sterilization, when irradiated with ultraviolet ray. The method has been established for evaluating deodorizing and contamination-preventive functions of the thin films in ultraviolet and visible rays. The project has also confirmed applicability of the techniques to the commercial products, and established the self-cleanable catalyst by combining the oxide catalytic function with the photocatalytic function.

    The experimental research was conducted with the aim of developing test/evaluation methods of plastic optical fiber (POF) and proposing a draft on the standards to IEC, and the FY 1999 results were outlined. In the study of the band measuring method, the equipment designed was compared/verified in the pulse method with the frequency sweep method equipment for quartz base optical fiber use to confirm the accordance. Effects were further studied of experimental conditions including exciting conditions. Also about the frequency sweep method, the same verification was made to see the accordance with POF measured values in the pulse method. In the analysis by theoretical calculation, obtained were the results by which the experimental results can almost be explained. In the experiment on the optical transmission, the bit-error-rate was measured by transmitting digital signals to POF. As a result, it was confirmed that there were close relations between the band width of POF, bit-error-rate and changes in receiving sensitivity. As to the above-mentioned band experimental method, strategy for standardization was studied, and the making of a draft on the standards was started which is to be proposed at the meeting of TC86/SC86/WG1.

    As to the development of organic base materials, the paper is going ahead with an evaluation, higher performance and further use as materials of basic optical properties of quirale nonlinear materials and organic conjugate base materials which are promising among organic low molecular materials. As the development of orientation control crystal growth technology, grooves for orientation control were formed on the surface of the lead glass substrate, from which thin film single crystals were obtained. The nonlinear response was studied of the glass where semiconducting fine particles dispersed in matrix glass.

    This research and development project is aimed at activation of the urushi industry and creation of the new business by utilizing the natural material by the name of urushi solution as the functional coating material satisfying the various conditions required for the coating solutions of the next generation, e.g., healthy, safety, comfortable and environmentally harmless characteristics. The urushi solution developed by this project is an innovative, creative one, which solves the major problems involved in the conventional solution, i.e., slow curing and causing eruption of the skin, by enzyme-aided polymerization and photopolymerization. The physiological activities of the urushi solution component and antimicrobial effects by the urushi layer, which are considered to be the potential functions of urushi, are also investigated for the project. The urushi-containing UV coating material means an ultraviolet-curable urushi/synthetic resin material, composed of refined urushi, a photopolymerizable acrylate compound and photopolymerization initiator. The refined urushi for the urushi-containing UV coating material can be adjusted for its degree of polymerization, as found by the experimental investigation of the catalyst for accelerating enzyme-aided polymerization, to improve curability. The confirmed physiological activities of the urushi component are accelerated solidification of the blood and manifestation of the anti-HIV function. The coating film of the refined urushi is found to be effective against Bacillus coli and Staphylococcus aureus. (NEDO)

    This paper describes water decomposition by using a hybrid cycle composed of thermo-chemistry and photo-chemistry. Ferric sulfate and HI are obtained from ferrous sulfate and iodine via photo-chemical reaction. This is an endothermic reaction of 10.8 kcal. Then, the photo-chemically reacted aqueous solution is electrolysed to separate HI, while Fe{sup 3+} (ferric ion) is reduced and converted into Fe{sup 2+} (ferrous ion). Oxygen is generated at this time. Since mixed potential is made from iron oxidation and reduction potential and iodine potential, the electrolytic efficiency is greatly influenced by electrode materials. Ideally, an electrode material that causes only the reduction of Fe{sup 3+}, but not other reactions is preferable. The HI is decomposed into hydrogen and iodine by electrolysis. Research is continuing to acquire hydrogen from HI thermo-chemically. Endothermic reaction heat of 7 to 8 kcal has been obtained in photo-chemical reaction, the heat quantity being close to the theoretical value of 10.8. A result close to the theoretical value may be expected if the electrode material problem is solved. The basic research will be continued for a high possibility of linking the research to a pilot plant in the future. (NEDO)

    Researches have been performed on water decomposition by multiplex utilization of solar beam, and the achievements in fiscal 1984 were reported. In fiscal 1984, activity coefficients for iron ions and iodide ions having been discussed by the previous fiscal year were derived, and free energy variation amount and accumulated energy amount generated as a result of photo-chemical reactions were derived. Values derived in the experiment were low, which are the values at room temperatures, and higher values are expected under elevated temperatures. In an experiment using a beam irradiation electrolytic tank, investigations were made on thermo-chemical isolation and electrolytic isolation of HI. Since HI is strongly acidic, it does not get liberated unless phosphoric acid concentration and temperature are increased, which is a condition opposing to easiness of the photo-chemical reaction. Therefore, an experiment on HI was performed not only on isolation due to heat, but also isolation by electrolysis, where the intended result was obtained. The mixed system of a photo-chemical system and an electrolytic system requires a system configuration that considers dynamic matching conditions, for which a system to perform measurements simultaneously on a large number of kinds was found effective.

    The research and development aims to increase the yield of light energy conversion in a photochemical reaction and thereby to increase the efficiency of the reaction of electrolysis of water. In the research, the electrochemical properties of Fe{sup 3+}/Fe{sup 2+} and I{sub 3}{sup -}/I{sup -} systems in a phosphoric acid solution are examined. As for the behavior of iodine ions I and I{sub 3}, their capacity coefficient rises with a rise in temperature at any phosphoric acid concentration level. Furthermore, more water molecules are disengaged from hydrated iodine ions with an increase in the concentration of phosphoric acid, and the now naked iodine ions are higher in activity coefficient. The behavior of iron ions in phosphoric acid is observed by use of a rotating electrode. Although the activity coefficient ratio of iron ions and iodine ions exerts a great influence in the process of conversion from light energy to chemical energy, the outcome of experiment indicates that the ratio is low for both iron- and iodine-based systems. It is consequently concluded that an energy conversion rate of approximately 10kcal/mol is expected from a photochemical reaction as in the case of hydrated systems. (NEDO)

    Reported herein are the FY 1985 research results on the combined water electrolysis cycles by effective utilization of sunlight. The tests for determining activity coefficient of an iron/iodine system is continued from the previous year, and the results are used to find the optimum conditions under which the photochemical and electrolysis reactions are effected simultaneously in a light-irradiated electrolysis tank. It is found that a photochemical reaction efficiency of approximately 0.3% is obtained at 5 W/cm{sup 2} as light intensity and 25 degrees C. For electrolysis of water by the multi-stage hybrid cycles, it is necessary for the reaction in each stage to proceed to almost the same extent so that it gives a just enough quantity of product for the subsequent stage. The data obtained are analyzed comprehensively, while taking the system matching conditions into consideration. The system for simultaneously measure two or more parameters, developed in the previous year, is equipped with a high-level language compiler of high effective speed, to simultaneously measure these parameters at shorter intervals.

    The report covers the outcome of a basic study of the splitting of water using photochemical reaction. The behavior of iron ions and iodine ions is important in the photochemical reaction in the phosphoric acid and in the energy exchange that follows, and the characteristics of iodine ions are investigated in detail. Since the response of a commercially available iodine ion electrode is slow in a strong phosphoric acid solution, a silver/silver iodide electrode is experimentally built, and is used in the investigation of the iodine ion activity coefficient. In the investigation, it is indicated that more energy is accumulated when temperature or concentration is higher. In the case where sunlight is used as the light source for photochemical reaction, it is necessary to perform optimal control in compliance with fluctuation in sunlight intensity. In the study, fluctuation in sunlight intensity is assumed to be composed of step waves, pulse waves, and sinusoidal waves, and a result of digital simulation is obtained by using a modelling method for control. For the convenience of computation, the number of cell division is set at approximately five, when the solution flow responsiveness and energy conversion utilization factor are found to be excellent.

    This paper describes research achievements in fiscal 1978 on water decomposition by using the thermo, photo and electro-chemistry mixed cycle. Fundamental experiments were carried out in a photo-chemical and electrolytic reaction tank to electrolyse as quickly as possible HI and iron (III) produced by photo-chemical reaction in the iodine-iron (II) system, and separate the products therefrom. The photo-chemical reaction was analyzed by using the spectro-photometry, and the degree of reaction progress was quantified by using the change in absorbance of I{sub 3}{sup -}. Since temperature rise due to sun beam irradiation accelerates reverse reaction, the apparent equilibrium position under the beam irradiation was moved from the product system to the original system as the temperature rises. An expression showing the reaction efficiency was introduced to indicate that beam collection enhances the efficiency. There is no electrolytic electrode material that reduces only iron (III) preferably, and electrolysing the aqueous product solution as it is results in low energy efficiency. In addition, as a result of discussing factors affecting the effect of HI decomposition (to acquire hydrogen) by using a heat diffusion column, it was revealed that maximum separation effect can be derived if the material is fed from the center of the column. Discussions were given also on other factors. (NEDO)

    The thin film structure of photocatalytic titanium oxide, capable of efficiently decomposing hazardous pollutants or the like, is refined to have a nanometric scale structure for a larger specific surface for the development of a photocatalytic thin film or powder film and for the development of decomposition capable air cleaner using a thus developed photocatalytic film. Described in this report are the results of a study conducted to elucidate the fabrication conditions, nanostructures, and photocatalytic features of titanium oxide thin films formed by spray thermolysis, RF (radio frequency) sputtering, reactive sputtering, and sol-gel process, a study of hazardous pollutant decomposing capability and nanostructure, the establishment of fabrication technologies, and the construction of a prototype air cleaner with the results of the said studies applied thereto. Among the various fabrication methods, the technology involving a hypersensitive thin film photocatalyst was established by combining the reactive sputtering method and the sol-gel method. It was found that the formation of prismatic crystals in the sol-gel method was the most important in achieving high performance in the hypersensitive thin film photocatalyst. (NEDO)

    Studies were made about methods for testing and evaluating plastic optical fiber (POF) for the purpose of submitting a proposition to IEC (International Electrotechnical Commission) for the methods to be internationally standardized. In this fiscal year, tests and analyses were conducted relative to the effects of the light source emission area size, wavelength, and axial displacement. Next, underfilled launch was studied from a practical viewpoint, and a method using a mode filter was proposed. Finally, round robin tests were conducted for each of the companies using overfilled launch and underfilled launch, and the reproducibility of measured values was grasped. In this fiscal year, a new study added, which involved a method for measuring structural parameters. Though POF was below standard as an object of IEC's gray scale method, yet it was found, thanks to the recently developed CCD (charge coupled device) cameras, that the method might also be applicable to POF. A groundwork plan was drafted on band test methods including the overfilled launch method toward international standardization. (NEDO)

    Efforts are made to submit a concrete, industrialization-capable proposition for a huge-volume high-rate data storage device to be connected directly to the optical fiber communication network. The terabyte optical disk storage device is based on the patented technologies owned by some organizations participating in the project, and embodies a 1-terabyte memory and a 1-Gbps data transfer rate in a CD-size disk with CD/DVD compatibility not affected. The road to a novel, huge-volume, ultrahigh-speed data storage device was open when the basic principle of collinear-polarization digital volume holography was successfully confirmed. A new optical disk medium was fabricated for recording digital volume holograms, and a success was attained in retrieving records on a terabyte optical disk evaluation system. A novel spatial light modulator was successfully fabricated using the magnetooptic effect. This will enable improvement on transfer rates in digital volume hologram retrieval devices and introduction of such devices into optical communication in the field of information technology. (NEDO)

    Discussions are being made on manufacture of hydrogen and oxygen from water decomposition using mixture cycles composed by thermo-chemistry, photo-chemistry and electrochemistry using ferrous sulfate and iodine. Photo-chemical reaction produces Fe(OH)SO{sub 4} and HI, but due to difficulty of isolating Fe(OH)SO{sub 4}, photo-chemical reaction that can obtain the compound as Fe{sub 2}(SO{sub 4}){sub 3} was introduced. A method was introduced that can perform HI isolation simultaneously while performing reaction to reduce Fe{sup 3+} and turn it into Fe{sup 2+} (generating oxygen) by means of electrolysing the liquid after the former reaction. The electrolytic process decomposes HI into hydrogen and iodine (discussions on thermo-chemical decomposition is also continued). Since the photo-chemical reaction can cause reverse reaction, discussions were given on the reaction process in order to suppress the reverse reaction and enhance the conversion efficiency. This paper describes the achievements during fiscal 1977. A quantification method was elucidated on individual iodine components so that it can be used for computerized control (measurement of absorbance of I{sub 3}{sup -}) . An electrolytic tank was discussed that decomposes and isolates photo-chemical reaction products before the reverse reaction occurs. Heat diffusion method was also discussed that isolates hydrogen from HI decomposition products. (NEDO)

    This paper describes achievements in research and development in the Sunshine Project in fiscal 1979 on water decomposition by using mixed cycle of thermo-chemistry, photo-chemistry and electrochemistry. In research on the light irradiation electrolytic process, with an objective of improving the reaction efficiency, discussions were given by raising light intensity on the irradiated surface as high as 13 times that of the sunlight. The subsequent process is electrolysis of products from photo-chemical reaction, and the product concentration should be high enough to have HI decomposition (hydrogen acquisition) proceed with high efficiency. Experiments were carried out at 0.03 to 0.1M as iodine concentrations (product HI concentration at 3%). A photo-chemical reaction rate of 80% was obtained at light intensity as high as 12 times that of the sunlight, and iodine concentration of 0.07 mM. The efficiency was 15%. Raising temperature causes the reaction rate to decrease, but it can be supplemented by raising the light intensity, where high concentration HI content was obtained. Rate controlling process in the reaction was elucidated from activation energies in the reaction process of each element on the iodine concentrations from 3 to 30 mM used in the photo-chemical reaction. Experiments were performed on HI decomposition (hydrogen acquisition) by using a heat diffusion column. Separation performance in a filled type column was worse than that in an empty type column, which requires future discussions. (NEDO)

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

    This program is aimed at development of iron-based catalyst suited for direct hydrogenation type coal liquefaction by elucidating the effects of the catalyst on the liquefaction reactions. The iron-based catalyst seems to act as the radical stabilizer rather than the reaction promoter, because the increased quantity of the catalyst and increased H{sub 2} pressure share the common pattern rather than the catalyst enhances the activity, which is associated with increased reaction temperature or residence time. This is more notably observed when the coal species is changed to brown coal. In other words, recombination of the decomposition products by polycondensation is accelerated in the presence of the catalyst in decomposition of brown coal from bituminous coal, with the result that the catalyst effects are more notably observed. Whether this results from difference in age between brown coal and bituminous coal or content of specific types of ashes should be elucidated, because this point is considered to deeply relate to eventual development of the liquefaction reaction system. The FY 1980 program includes the primary screening of different types of iron compounds and tests of some iron-metal-based catalysts. (NEDO)

    Described herein are the FY 2000 results of the survey on the technological trends of utilizing the reactions with metals in a living body, noting the bio-processes effectively coping with the environmental problems. The effects of heavy metals on microorganisms have been investigated on the molecular biology level, but are not fully elucidated. Recently, the microorganisms capable of converting inorganic metal ions in water into the insoluble compounds have been known, leading to possibility of bioremediation to solve pollution by heavy metals, which have detrimental effects on human health. Heavy metals must be recovered, because they are not extinct by decomposition. The plant aided purification has been attracting attention to cope with heavy metals accumulated in soil. Application of bacteria-aided leaching, which is adopted as one ore smelting process, to the technologies for utilizing metals in a living body has been expected, because diversified activities of inanimate matters in extreme environments have been known. Recently, bio-machining of metals aided by Thiobacillus ferrooxidans, one species of independent nutrient bacteria capable of eating metals, has been developed to a potentially viable stage. (NEDO)

In the development of large quantity hydrogen production/supply technology, assembly/operation of 7,500cm{sup 2} x 6 electrolytic cells were conducted, and it was confirmed that the hydrogen production capacity per cell was 3Nm{sup 3}/h. The final target for enlargement was achieved. In the study of the total system, the conceptual design was made for 'high concentration CO2 containing natural gas use CO2 recovery utilization system,' and 'biomass resource use methanol synthesis system.'

    Described herein are the FY 2000 results of the survey on the technological trends of utilizing the reactions with metals in a living body, noting the bio-processes effectively coping with the environmental problems. The effects of heavy metals on microorganisms have been investigated on the molecular biology level, but are not fully elucidated. Recently, the microorganisms capable of converting inorganic metal ions in water into the insoluble compounds have been known, leading to possibility of bioremediation to solve pollution by heavy metals, which have detrimental effects on human health. Heavy metals must be recovered, because they are not extinct by decomposition. The plant aided purification has been attracting attention to cope with heavy metals accumulated in soil. Application of bacteria-aided leaching, which is adopted as one ore smelting process, to the technologies for utilizing metals in a living body has been expected, because diversified activities of inanimate matters in extreme environments have been known. Recently, bio-machining of metals aided by Thiobacillus ferrooxidans, one species of independent nutrient bacteria capable of eating metals, has been developed to a potentially viable stage. (NEDO)

    The growth temperature range was greatly expanded of atomic layer epitaxy (ALE) expected as the growth process of ultra-thin stacks. Ga layers and As layers were formed one after the other on a GaAs substrate in the atmosphere of trimethylgallium (TMG) or AsH{sub 2} supplied alternately, by KrF excimer laser irradiation normal to the substrate. As a result, the growth temperature range was 460-540{degree}C nearly 10 times that of 500 {plus minus} several degrees centigrade in conventional thermal growth method. Based on the experimental result where light absorption of source molecules adsorbed on a substrate surface was larger than that under gaseous phase condition, new adsorbed layer enhancement model was proposed to explain above irradiation effect verifying it by experiments. As this photoenhancement technique is applied to other materials, possible fabrication of new crystal structures as a super lattice with ultra-thin stacks of single atomic layers is expected because of a larger freedom in material combination for hetero-ALE. 11 refs., 7 figs.

    Researches were conducted for the goal of proposing a totally new process enhanced in efficiency and energy saving, and capable of CO2 separation. In fiscal 1997, hydrocarbon materials were reformed by oxygen separated within a system allowing fuel cells to generate power efficiently, when all the emitted CO2 was separated and recovered within the system. Furthermore, cold heat was utilized for the acquisition of liquefied CO2 gas products. A part of oxygen separated at the fuel cell cathode was recycled into the combustion section external to the tubular reaction reformer, and CO2 was separated by mere cooling from the combustion products for the simultaneous production of by-products such as high-purity nitrogen gas and liquefied CO2 for a great improvement in economy. In fiscal 1998, the system was improved. Proposed then was a new system in which an oxygen partial oxidation type reformer assumed the nuclear role, separating all the oxygen at the cathode, reusing part thereof for oxygen enrichment, and feeding the rest thereof into the reformer. The design realized the recycling of the whole of the products of the two cell electrodes into the reformer for the maximum reuse of the products of the hydrogen/oxygen separation function. (NEDO)

    The energy structure of semiconductor microcrystals with less than 10nm particle size is different from that of bulk semiconductor, and the reducing force of electrons and the oxidizing force of holes produced by light in microcrystals are larger than those of bulk semiconductor. Focusing on the application of semiconductor microcrystals to photocatalysis, the effects of the particle size and surface conditions of particles on photocatalytic activity are discussed. It has been shown that the change in the characteristics of semiconductor microcrystals depends on particle size, and microcrystals with narrow distribution of particle sized is necessary for the study of the characteristics of semiconductor microcrystals. An example of high efficient progress of CO2 direct reduction by the use of semiconductor microcrystals is introduced. It has been made clear that the photocatalytic activity of semiconductor is improved when a small amount of electrode catalyst is supported in it. A unique photocatalytic reaction which can not be observed with bulk particles can be progressed by the use of high oxidation and reduction ability caused by quantum size effect of semiconductor microcrystals. 26 refs., 2 figs., 1 tab.

    Titanium oxide has been developed which can be put to practical use in photocatalysis, and trials have been carried out for the application to environmental processing. Some of the cases are quoted to investigate means for the application of the photocatalysis study. During the process of improving the light resistance of titanium oxide pigments, various knowledge on photocatalytic phenomena has been obtained, and titanium oxide having a strong enough activity suitable for practical use is obtained based on the knowledge. There are two methods for the application of photocatalysis to decomposition and deodorization of malodor in living space. Fixation of NOx has been studied to solve the problem of air pollution. A huge reactor is required if photocatalysis is applied to the treatment of a large quantity of water. Various kinds of approach may be needed to structure a compact reactor suitable for practical use. 14 refs., 3 figs., 2 tabs.

    Hydrophilicity results when the surface of titanium dioxide is reduced for the specified oxygen to be replaced by hydroxyl groups. The ease with which such a structural change occurs is subject to variation between titanium dioxide crystal surfaces, and is dependent greatly on the atmosphere. No hydrophilic trend is observed in an atmosphere of oxygen only without moisture and, in darkness without light, hydrophobicity occurs early. Although the contacta angle titanium dioxide with water with stability is not known, yet it is presumed, on the analogy of the case of strontium titanate, that it is in the range of 20-40 degrees. A hydrophilic trend below the range is attrributed to structural changes. The control of surface wettability is one of the basic tasks to fulfill in various kinds of mechanisms and manufacturing processes. The technology of wettability control using a titanium dioxide coating which is quite durable will be applied not only to functions involving defogging, dripproof, and self-cleaning, but also to the control of heat transmission in the mechanism and to the bonding process.

    The secondary hydroprocessing process in the two-stage hydrogenating liquefaction equipment under development at Nippon Brown Coal Liquefaction Company uses a fixed bed system. This paper describes operation of a bench reaction equipment using catalyst used in the pilot plant to compare it with fresh catalyst, and compare characteristics of the bench scale equipment with those of the pilot reactor. The catalyst is Ca-Ni-No/Al2O. The reaction was carried out in a gas-liquid downward parallel-flow fixed-bed reactor using deashed oil (DAO) with the same material as that used in the pilot plant and the same equilibrium solvent. The experiment result indicates that the used catalyst had its activity fallen below the fresh catalyst, but its temperature dependence was identical, and the selectivity on products of both catalysts was also identical. The result of reactions in the bench scale equipment clarified that the relationship between the DAO conversion rate and denitrogenation activity and the relationship between fa and H/C in the products are in good agreement, and that there is no difference in reaction selectivity. 5 refs., 6 figs., 1 tab.

    The Research Center for Carbonaceous Resources was established in April 1991 for the purpose of developing a comprehensive process for converting carbonaceous resources into clean fuels or into materials equipped with advanced functions. In this report, the track records etc. of the center are introduced. Under study in the conversion process research department is the organization of a comprehensive coal conversion process which will be a combination of solvent extraction, catalytic decomposition, and catalytic gasification, whose goal is to convert coal in a clean way at high efficiency. Under study in the conversion catalyst research department are the development of a coal denitrogenation method, development of a low-temperature gasification method by use of inexpensive catalysts, synthesis of C{sub 2} hydrocarbons in a methane/carbon dioxide reaction, etc. Other endeavors under way involve the designing and development of new organic materials such as new carbon materials and a study of the foundation on which such efforts stand, that is, the study of the control of reactions between solids. Furthermore, in the study of interfacial reaction control, the contact gasification of coal, brown coal ion exchange capacity and surface conditions, carbonization of cation exchanged brown coal, etc., are being developed.

    Noticing that metal oxides have photocatalysis for reduction in NOx concentration and examining effects of the TiO2 selected on removal of pollutant, the paper proposes a direct purification method for the air environment. Since TiO2 causes electron excitation meeting near ultraviolet irradiation, it manifests a catalytic function for various oxidation/reduction reactions. Details of the reaction mechanism are unknown, various active oxygen species generated on the surface of TiO2 under light irradiation oxidize NOx and acquire it as nitric acid on the surface. It is found that mixture of activated carbon of low hygroscopicity with TiO2 is effective to prevent a tendency of NO to desorb before NO becomes nitric acid. What 40% of the catalyst with fluorine resin is formed into like a sheet shows a high removal rate even in the amount of ultraviolet irradiation in a winter cloudy day in the wide range of 0.5 - 95.0% of NOx and SO2, and if the photocatalyst is applied to the side wall of city buildings, the NOx concentration is estimated to be reduced by as much as 20%. 5 refs., 3 figs.

    Selective photoexcitation and photoionization of neodymium atoms were studied basically by using laser. Also, using their properties, feasibility of laser material purification (LPM) technology in gaseous phase was presented. In the selective 3-step ionization, laser beam with two kinds of proper wave length causes resonance exitation of the target element, which goes up to the excitation level of the first step, and the element is ionized by the second laser beam and the third laser beam. The 3-step ionization scheme by a single wave length laser beam of 577.612nm was used for the ionization of Nd. Nd ionized selectively by laser beam was recovered as thin layer at the negative potential side of plane electrodes placed at both sides of the laser irradiation area. In the layer formed by the TPD technology with this scheme, it is possible to decrease impuritis such as Pr by 1/16 and to form highly purified thin layer. 13 refs., 12 figs., 1 tab.

    If fiber transmission light can be controlled in a stabilized polarization state, realization of coherent optical communication is anticipated. In the case of adopting it to OPGW, however, it is necessary to compensate high speed polarization variation caused by lightning strike. But this was difficult in the conventional method. Accordingly, a high speed polarization control method was proposed which uses an electric effect of lithium niobate (LN) crystals. In the study, a polarization control unit was manufactured based on the method proposed and the performance was demonstrated. As a result of measuring output light with input light changed in every state of polarization, the object horizontal polarization component obtained a stabilized light intensity at {+-}0.1dB, and a light intensity of the component slipped out of the horizontal polarization was suppressed under -20dB. To cope with the polarization variation by lightning strike, it is necessary to make the control delay 10{mu}sec or below, and improvement in processing unit, etc. may make it possible since LN crystals respond below 1{mu}sec. High speed control of the infinitely continuing arbitrary polarization variation became possible. 14 refs., 19 figs.

    Catalysts with strong decomposing power are necessary in removing the stink of toilets and diapers, the smoke of cigarettes, lampblack in kitchens and mold in bathrooms etc. One of such catalysts attracting attention is titania (Ti02) photocatalyst. Titania has a strong oxidizing force due to its ability to absorb light with a wavelength under 400nm, and meanwhile this substance itself is chemically stable and tender to environment. In this paper, simultaneously with the introduction of the design examples applying the performance and properties of such catalysts, the evaluation on the performance of utility photocatalysts is described. The examples of using tiles with titania coated on ceramic tiles and the photocatalysts obtained by fixing supermicro-particles of titania catalysts with fluorine resin as a binder to decompose the oil vapor near a ventilation fan above a kitchen range and the tobacco tar whose concentration level is as in a living room are introduced as the design examples of utility photocatalysts. 13 refs., 6 figs.

    Tar sand bitumen is petroleum-based ultra-heavy oil, and has a great amount of reserve like coal. However, there are still a lot of problems for its highly effective utilization. This paper discusses whether the light components in bitumen show independent behavior during the thermal cracking of heavy components, or not. Solvent effect and reaction mechanism during the thermal cracking are also derived from the change of their chemical structures. Athabasca tar sand bitumen was separated into light and heavy fractions by vacuum distillation based on D-1660 of ASTM. Mixtures of the both fractions at various ratios were used as samples. Negative effect of the light fraction on cracking of the heavy fraction was observed with dealkylation and paraffin formation Polymerization of the dealkylated light fraction to the heavy fraction was suggested due to lack of hydrogen in the thermal cracking under nitrogen atmosphere, which resulted in the formation of polymer. 3 refs., 6 figs.

    Recently various studies have been conducted concerning the state changes of materials obtained through mechanical alloying (MA) or mechano-chemical (MC) processing. What is noticeable is the quasi-steady state of almost all the materials obtained through various processes including MA and MC, and that the super cooling, supersaturating and high residue distortion realized under unbalanced conditions have not been clarified. In other words, the tracing capability to the external binding conditions is low. In this report, the appearance of the high temperature phase and high pressure phase obtained through MA or MC processing, the forming of amorphous, the mesomerism of the amorphous materials, the interesting phenomena generated by combination between the mechanical disturbance and chemical reactions were discussed with concrete examples, and a steady dissipative organization theory was approached from the viewpoint of dissipative structure development which is equal to the forming process of the quasi-steady phase. 34 refs., 2 figs.

    This paper introduces the surface photo reaction processes using synchrotron radiation, and its application. A synchrotron radiation process using soft X-rays contained in electron synchrotron radiated light as an excited light source has a possibility of high-resolution processing because of its short wave length. The radiated light can excite efficiently the electronic state of a substance, and can induce a variety of photochemical reactions. In addition, it can excite inner shell electrons efficiently. In the aspect of its application, it has been found that, if radiated light is irradiated on surfaces of solids under fluorine-based reaction gas or Cl2, the surfaces can be etched. This technology is utilized practically. With regard to radiated light excited CVD process, it may be said that anything that can be deposited by the ordinary plasma CVD process can be deposited.

    An electrolytic solution has been recognized as an ion transporting system since the oldest time in the history of electrochemistry, and the chemistry related thereto forms the most basic field of electrochemistry. In this article, the progress of chemistry concerning electrolytic solutions since M. Faraday is briefly stated, and in view of very scanty structural knowledge available on other solutions in comparison with the structure of water on which extensive studies have been made, the respective structures of such non-aqueous solutions as the mixed solvent of N,N-dimethylformamide (DMF)-acetonitrile (AN) and the mixed solvent of dimethylsulfoxide (DMSO)-2,2,2-triphloroethanol (TFE) are studied. In addition, concerning the solvation when ions exist in such a non-aqueous solvent mixed system, the selective solvation of Cu {sup 2+} ions in the DMF-AN and Cu {sup 2+} as well as Cl {sup {minus}} ions in the DMSO-TFE is respectively explained, and the solvent effect, etc. of Cu {sup 2+} ions and Cl {sup {minus}} ions on the complex forming reaction are discussed. 17 refs., 8 figs., 2 tabs.

    Selective composition of optically active compounds by use of biocatalysts is discussed. No search is made for any particular microbes or enzymes, but predetermined ones are used. For an increase in the selective yield of L-type carnitine by reducing 4-chloroacetoacetic acid ester using baker`s yeast, the ester length should be enlarged to that of octyl ester. Just as in this case, steric control by ground substance modification is often effective. Lipase helps on esterification which is contrary to hydrolysis in an organic solvent and, even in the optical division in this process, steric control by ground substance modification (for example by changing the structure of the acyl section) is effective. Immobilization of biocatalysts for use in reaction occasionally exerts some effect on stereoselectivity. Two types of enzymes may be participating in a reaction and inhibiting selectivity, and then a two-layer system of water and organic solvent may be effective in performing steric control over the situation. Another measure is to inhibit the activity of either of the two enzymes by use of a selective inhibitor utilizing enzyme reaction. The kind of solvent is also an influential factor. 11 refs., 7 figs.

    For artificial coalification, condensation reactions of aromatic ring and activated compounds produced by dehydrating reaction of glucose were studied experimentally. In heat treatment experiment in water, three reaction specimens such as glucose, glucose and phenol, and glucose and benzaldehyde were fed into an autoclave together with distilled water, and subjected to reaction at 180{degree}C under spontaneous pressure for 50 hours. In hydrogenation experiment, the specimens were fed into an autoclave together with tetradecane and sulfurization catalyst, and subjected to reaction at 350{degree}C under initial pressure of 9.8MPa for 2 hours for gas chromatography (GC) analysis of products. As the experimental result, the reaction between glucose and aromatic ring in heat treatment in water occurred between aromatic ring and active fragment with a mean carbon number of 4-5 produced by decomposition of glucose. The reactivity was higher in benzaldehyde addition than phenol addition. 3 refs., 4 figs., 1 tab.

    Since light can be transformed into electricity, electrolysis of water using light is possible naturally, and photosynthesis in the nature is based on this principle. The reaction field in which electrochemical energy necessary for decomposition of water is generated using light at the first process of photosynthesis is a biofilm less than 10nm thick which is called thylakoid film. In this article, the effects are roughly explained which have been made for constructing an artificial system corresponding to the thylakoid film. Accumulation of knowledge of the molecular level is necessary for the construction of the artificial system and the three dimensional structure concerning the reaction center of photosynthetic bacteria has been determined. At the reaction center, oxidation species of electron donor and reduction species of electron acceptor are generated by charge separation which succeeds electron excitation by light energy. In order to lead the above process to materialistic production, efforts are being made for construction of a reaction center model compound for artificial photosynthesis from both physical chemistry and organic chemistry and the positive results have steadily been obtained in the development of photocatalysis of a semiconductor. 9 figs.

    This paper shows the impact of the irradiation from an additional light source during the deposition of hydrogenated amorphous silicon by photo-CVD deposition. Using a mercury sensitized photo-CVD process from Disilan (Si {sub 2} H {sub 6}) and hydrogen, silicon was deposited. A 40W low pressure mercury lamp was applied as the light source. A portion of the substrate was in addition irradiated using an Xg-He lamp through a thermal filter. Irradiation of the substrate using only Xg-He lamp produced no deposition, since this light has a wavelength which is too long to produce the SiH {sub 3}-radicals needed for Si deposition. The additional Xg-He light source was discovered to cause an increased thickness of deposited a-Si:H film and a transmission of the band structure. The reasons of these are considered that the influence of irradiation is not limited to film thickness, but that irradiation also impacts the composition of the a-Si:H film so as to cause a reduction in the hydrogen content. 10 figs., 1 tab.

    This paper outlines present state of the feeding system in the light access system in consideration of backup in case of home power failure. In the optical communication, equipment with bilateral conversion function for light and electricity has to be installed both on communication service side and home side. Outline of the light access system and equipment requiring backup are shown. The following items are explained: main types of the light access system, such as FTTC (fiber to the curb), FTTP (fiber to the pole), FTTH (fiber to the home) and HFC (hybrid fiber coax), and the feeding system; problems on feeding system for the light access system. Key elements of ONU (optical network unit) for FTTH and construction of the ONU power source are illustrated. The ONU power source is composed of a backup power supply unit and main body supply unit. Backup power is indispensable to the ONU and analog telephones: output is supplied by the backup batteries in power failure. For miniaturization of the backup power source, power supply circuits and backup batteries have to be miniaturized simultaneously. History of miniaturization is explained on the experimental models. 6 refs., 7 figs., 1 tab.

    Experiments of temperature measurement were conducted in high temperature and high pressure geothermal wells using optical fiber sensor. A temperature measurement system using optical fiber sensor was applied to geothermal wells. Working availability was confirmed under the condition up to the depth of 1,750 m and the temperature of 240 centigrade. Observed values agreed well with those observed by the conventional temperature logging. Durability of the optical fiber sensor was also sufficient. The maximum standard deviations of measured values were 1.3 centigrade at the depth of 1,750 m at 195 centigrade for the loop-type sensor, and 3.7 centigrade at the depth of 365 m at about 200 centigrade for the single-end sensor. Although the accuracy was inferior to the conventional measurement using a thermo couple, it was enough to be applied to usual temperature logging. Furthermore, for this system, the temperature profile in the whole well can be monitored, simultaneously. Through the experiments, the detailed successive change of temperature profile accompanied with the water injection can be clearly illustrated. 3 refs., 7 figs.

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

    The reactivity of oxygen methylated coal was studied to control hydrogen bond in bituminous coal liquefaction and intermolecular cohesion such as van der Waals force. In experiment, crushed and dried Illinois coal of 100mesh or less was used as specimen, and oxygen methylated coal was prepared by Liotta`s method using tetrabutylammonium halide. Coal liquefaction was conducted in an electromagnetic agitation autoclave using tetralin solvent under initial hydrogen pressure of 100kg/cm{sup 2} while heating. The molecular weight distribution of the products obtained was measured by gel permeation chromatography (GPC) analysis. The experimental results are as follows. The effect of intermolecular cohesion in bituminous coal on the reactivity is mainly derived from decomposing reaction from preasphaltene to oil. Yields of oil fraction by methylation increase corresponding to release of intermolecular cohesion. Since the thermal release is promoted with temperature rise, the difference in yield due to different treatments decreases. 5 refs., 3 figs., 1 tab.

    An experiment and the examination were carried out in order to elucidate the optimum conditions in the falling liquid film reaction method, in the conversion of solar energy using the decomposition reaction of 2-propanol. The device for the experiment was constituted of a reaction container, tubular pump, cooling pipe, sampling container for effluent from the upper and lower part of the reaction container, and gas burette. Examined in the experiment were various factors such as a fibrous activated carbon (catalyst support), ratio for carrying catalyst, catalytic composition and heating temperature. In the experiment, with the temperature inside the reaction container fully stabilized under prescribed conditions, measurement was done for the hydrogen generation by the gas burette for 10 minutes as well as for the sampling of effluent. The experiment revealed that the heat utilization ratio reached the maximum of about 27% when the heating temperature was 90{degree}C using a catalyst with the ratio of RU and Pt 1 to 1 and the ratio for carrying catalyst 10wt%, so that a great improvement was obtained in the heat utilization ratio at a low temperature. Also obtained was a large inversion ratio of about 15%. 4 refs., 6 figs., 5 tabs.

    To design the coal liquefaction reactor of large scale plant in future, it is important to understand characteristics of fluid dynamics within the coal liquefaction reactor. In this study, to measure the fluid dynamics of liquid phase within the coal liquefaction reactor operated under high temperature and high pressure coal liquefaction condition, neutron attenuating tracer (NAT) technique, one of the tracer test methods, was applied using 1 t/d coal treating PSU. The residence time of liquid phase within the reactor can be measured by utilizing property of neutron of being absorbed by materials. The tracer was injected at the inlets of first and third reactors, and the neutron was counted at each outlet. The concentration of tracer was derived from the discrete value, to determine the residence time distribution of liquid phase. The mean residence time of liquid phase in the single first reactor and in the total three reactors were prolonged under the severe operation conditions of liquefaction. The more severe the liquefaction operation condition was, the more active the mixing of liquid phase was in the first reactor. It was found that the progress of reaction was accelerated. 2 refs., 5 figs., 1 tab.

    Through the hydrogenolysis of Wandoan coal and Tanito Harum coal which are used for the NEDOL process, differences of liquefaction characteristics between them were found. The purpose of this study is to grasp these differences as differences of chemical structures of oil fractions. The compound type analysis was conducted for oil fractions obtained at varied reaction temperature for varied reaction time. Coal liquefaction characteristics of these coals were discussed by relating oil yields and chemical structures. For Tanito Harum coal, yields of gas and oil were considered to be lower than those for Wandoan coal, which reflected that the contents of partially hydrogenated hydroaromatics in oil fraction from the former were lower than those from the latter, and that the remarkable change of composition did not occur with the progress of the reaction. For both the coals, the remarkable changes in the average molecular weight of oil fraction were not observed with the progress of the reaction. While, the content of methane gradually increased with the progress of the reaction, which suggested that oil was gradually dealkylated. 5 figs.

    For the removal and recycle of CO2, a global warming gas, utilization of photosynthesis by micro algae is investigated. Formed micro algae are decomposed into CO2, H2O and CH4 again, which does not result in the permanent fixation. For the effective utilization of these micro algae, creation of petroleum alternate energy was tried through the co-liquefaction of micro algae with coal. Were investigated influences of the reaction temperature during the co-liquefaction and influences of catalysts, such as Fe(CO)5-S, Ru(CO)12, and Mo(CO)6-S, which are effective for the coal liquefaction. Micro algae, such as chlorella, spirulina, and littorale, and Yallourn brown coal were tested. It was found that co-liquefaction of micro algae with coal can be successfully proceeded under the same conditions as the liquefaction of coal. The oil yield obtained from the co-liquefaction in the presence of Fe(CO)5-S, an effective catalyst for coal liquefaction, agreed appropriately with the arithmetical mean value from separate liquefaction of coal and micro algae. It was suggested that pyrrhotite, an active species for coal liquefaction, was sufficiently formed by increasing the addition of sulfur. 2 refs., 7 figs., 1 tab.

    Mechanical grinding (MG) with mechanically stimulated reaction was performed on metal/polymer mixed powders. The starting materials used in this study were the metals of Mg, Ti and Mg{sub 2}Ni powders, arid polymer of PTFE, PVC and PE powders. The MG process was investigated using XRD, IR, SEM and TEM. According to XRD results, magnesium fluoride (MgF{sub 2}, TiF{sub 2}) and chloride (MgCl{sub 2}) were detected from MG products of the Mg/PTFE, Ti/PTFE and Mg/PVC blending systems, respectively. Explosive reaction was found during MG of both Mg/PTFE and Ti/PTFE. It was also confirmed by XRD results that the production of MgF{sub 2} had already been formed just before the explosive reaction in Mg/PTFE system. It was found from IR analysis that C-C single bond in the polymers, not only both in PTFE and PVC but also in PE, changed to double bond C=C. Hydrogen produced due to decomposition of PE on blending Mg{sub 2}Ni/PE was absorbed into C-Mg{sub 2}Ni-H as amorphous solutes. These mechanically stimulated reaction was powerful method for decomposition of engineering plastics. (author)

    Regarding excitation and deexcitation due to collision of electrons and deexcitation due to collision of baryons in nonequilibrium plasma, explanation is made about the general characteristics of the elementary processes involving their formation and disappearance and about the prediction of their sectional areas and velocity constants. As for the process of the formation of excited atoms and molecules by collision of electrons, it may be divided into the direct excitation in the ground state, excitation and light emission toward the resonance state, reexcitation and transformation of excited particles, recombination of electrons and positive atomic ions, and dissociation and recombination of electrons and positive molecular ions. As for the process of the disappearance of excited particles, there exist various courses it may follow, and it is quite complicated because it is dependent on the types of particles involved and the conditions the process proceeds under. Although the skeleton has been built of the theory of derivation of the sectional area of excitation due to collision of electrons and atoms/molecules, yet it is accurate enough only when applied to simple atomic/molecular systems, is far from satisfying in general, and is to be augmented by data from future experiments. 22 refs., 3 figs., 1 tab.

    This paper describes mainly a reactive separation membrane reactor, introducing its principle, history, membrane materials, and permeation mechanism. When a product is removed out of a system, the equilibrium shifts to the product side according to the law of Le Chatelier-Braun. The reaction invert ratio in this case can be explained with an idea that it is based on the equilibrium theory and the velocity theory. Simulations are also performed using numerical analyses. Historically, studies had been made in the 1980{prime}s on reaction velocity theory, permeation mechanisms, and engineering approaches. Reactions as the object of the studies were focused mainly on dehydrogenation react ion. Thereafter, studies have begun on permeation of substances with new membrane other than hydrogen and on biological field. Membrane materials used then were heat-resistant and chemically stable inorganic materials. Recent reports include polymer membranes, hydrophilic and hydrophobic Membrane (in biological field), liquid membranes, and composite membranes. Separation membranes may be divided largely into porous membranes (with micro ports ranging from several {angstrom} to several hundred {angstrom} )and non-porous membranes, each having its specific permeation mechanism. 9 refs., 3 figs., 2 tabs.

    For the purpose of toughening the matrices of fiber-reinforced plastics (FRPs), the effect of thermosetting/thermoplastic polymer alloys based on cyanate ester alloys is investigated. In the experiment, materials are heated and then allowed to set, which are mixtures of 87.0-43.5wt% of cyanate ester resin, 0-43.5wt% of epoxy resin, and 13.0wt% of soluble polyimide. FRP properties are examined by measuring the after-shock compressive strength, flexural elasticity and flaxural strength, and by performing morphology observation. It is then found that a cyanate ester/soluble polyimide system forms a polymer alloy with phase separation, that its glass transition temperature does not drop, and that the rupture strength is increased approximately twice. A carbon fiber-reinforced plastic (CFRP) incorporating this system is twice higher in after-shock compression strength than a CFRP incorporating a cyanate ester. The system withstands high temperatures, retaining at 200degC approximately 90% of the elastic modulus it exhibits at room temperature. 15 refs., 16 figs.

    In relation to coal liquefaction, the effect of inorganic minerals on liquefaction reactivity and the effect of hydrofluoric acid (HF) treatment on organic molecular structure of coals were studied by demineralization of low-rank coals in HCl or HF solution. In experiment, Taiheiyo coal specimen was deashed in HCl solution at 25-70{degree}C for 6 hours while agitating, and in addition, deashed in HF solution. Hydrogenolysis of the deashed coal specimen was conducted using tetralin or methylnaphthalene as solvent under initial hydrogen pressure of 1.96MPa at reaction temperature of 693K for 60min. The experimental results are as follows. The ash content of Taiheiyo coal hardly offers catalysis in hydrogenolysis reaction. Carboxyl group increases in demineralization of coal because of breakage of bridged bonds. Organic structure of coal changes by demineralization in dense HF solution. Change in organic structure of coal by demineralization in dense HF solution is dependent on treatment temperature. 2 refs., 4 figs., 1 tab.

    In order to clarify a humification process in the early stage of coalification, the nitrogen functionality of prepared glucose-glycine condensate was studied experimentally. In experiment, the condensate was prepared by heating the mixture of glucose, glycine and water in a autoclave at 130{degree}C for 50 hours, and furthermore heating the produced solid material in water at 300{degree}C. After the condensate was hydrocracked, the fraction, condensate and hydrocracking residue were analyzed by elementary analyzer, {sup 13}C-NMR, XPS, FT-IR, capillary GC-FID/NPD and GC-MS. As a result, the glucose-glycine condensate could be arranged on the basis of three types of nitrogen such as pyridine, pyrrole and quaternary amine type. Pyridine type nitrogen increased, while quaternary amine type one decreased with an increase in heating treatment temperature. Rich pyrrole type nitrogen and poor pyridine type one were found in light nitrogen compounds in hydrocracked products. 2 refs., 4 figs., 2 tabs.

    It is important to cool a photovoltaic (PV) panel, because increased panel temperature is accompanied by decreased power generation efficiency. The authors have proposed a PV power generation system combined with an adsorption chiller driven by low-temperature heat, and simulated temperature changes during the desorption cycle, where the chiller utilizes endothermic reactions of an adsorbent during the desorption cycle. Described herein are results of the tests carried out to validate possibility of controlling panel temperature increase. The system consists of the PV panel with which a bed packed with an adsorbent is monolithically combined, condenser and evaporator. It generates power during the daytime by sunbeams, and provides low-temperature heat during the nighttime by the evaporator. In particular, ice can be produced when methanol and activated coal are used as the adsorbate and adsorbent. It has an advantage of effective utilization of energy as the heat source, which has been merely dissipated by the conventional system in the air. Such a system is expected to be useful for promoting effective utilization of solar energy and for peak power shaving in summer. The initial targets are achieved by the tests. 4 refs., 10 figs.

    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.

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

  1. A Pub/Sub Message Distribution Architecture for Disruption Tolerant Networks

    Carrilho, Sergio; Esaki, Hiroshi

    Access to information is taken for granted in urban areas covered by a robust communication infrastructure. Nevertheless most of the areas in the world, are not covered by such infrastructures. We propose a DTN publish and subscribe system called Hikari, which uses nodes' mobility in order to distribute messages without using a robust infrastructure. The area of Disruption/Delay Tolerant Networks (DTN) focuses on providing connectivity to locations separated by networks with disruptions and delays. The Hikari system does not use node identifiers for message forwarding thus eliminating the complexity of routing associated with many forwarding schemes in DTN. Hikari uses nodes paths' information, advertised by special nodes in the system or predicted by the system itself, for optimizing the message dissemination process. We have used the Paris subway system, due to it's complexity, to validate Hikari and to analyze it's performance. We have shown that Hikari achieves a superior deliver rate while keeping redundant messages in the system low, which is ideal when using devices with limited resources for message dissemination.

    Researchers of the Corning Glass Works have made great contribution to the development of practical use of optical fibers. The effort of the Corning Glass Works in technological development and overseas production was introduced. Corning developed the outer vapor deposition (OVD) method suitable for large scale production. Later, the so-called vertical axial deposition (VAD) method was developed also in Japan, and a technology for quantity production of high quality optical fibers was established. The bases of the Corning's approach were respect for intellectual property and strategic market development, indicating that Corning had strategy for overseas production from the early stage (early stage of market growth) in addition to product supply strategy. Optical fiber is one of the strategic materials whose export is controlled in many countries, and the transfer of the related technology is also controlled. 1 fig.

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

    A purple membrane extracted from bacterial halobacterium salinarium is a membrane prepared by two-dimensionally crystallizing bacteriorhodopsin (bR) which is a photo-sensitive protein. When retinal chromophore in the bR absorbs photons, isomerization occurs, so that light cycle of bR comprising a light intermediate of different absorption spectrum occurs. Since this purple membrane has a high stability and a high repetition durability, a study of the application of the same to a rewritable holographic recording medium has been made in recent years. This paper describes an example in which the refractive index variation of a purple membrane the optical characteristics of which varies due to variation is applied to light beam control. The paper introduces a Fabry-Perot resonator as an optical element capable of carrying out light control by utilizing refractive index variation. The paper further describes the possibility of materialization of an optical logic comprising a combination of light-irradiation refractive index variation and a Fabry-Perot resonator and having nonlinear input/output characteristics such as the bistablity owing to the feedback effect in the resonator. 7 refs., 3 figs.

    Single atomic layer epitaxy (ALE) aims at controlling a growing film at a precision of single molecular layer. In this article, it is reported that the growth temperature range of ALE was expanded by the vertical irradiation of KrF exima laser (248 nm) onto the substrate for the ALE growth of GaAs using the metalorganic chemical vapor deposition (MOCVD) method. Thanks for the results of the above experiment, it was demonstrated that the irradiation effect was not thermal, but photochemical. In addition, this article studies the possibility of adsorption layer irradiation and surface irradiation as the photo-irradiation mechanism, and points out that coexistence of both irradiation mechanisms can be considered and, in case of exima laser, strong possibility of direct irradiation of the adsorption layer because of its high power density. Hereinafter, by using both optical growth ALE and thermal growth ALE jointly, the degree of freedom of combination of hetero ALE increases and its application to various material systems becomes possible. 16 refs., 6 figs.

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

    Manufacture is under way of an optical interference-type micro accelerometer making use of the micromachining technology and an optical fiber measuring system for detecting microseismic waves in the ground. The sensor is required to be capable of detecting acceleration 0.1-1gal in amplitude, to be flat in amplitude characteristic in a frequency range of 10Hz-several kHz, to be ensured of straight phase characteristics to enable the measurement of transient phenomena, to be low in cross sensitivity, and to be high in resistance to water, pressure, and heat. The sensor is constructed in the following way. In the process for treating silicon, anisotropic etching is performed for the formation of a gap between the fiber end face and oscillator, boron is diffused, a stopper is formed, and then the silicon is subjected to penetrating etching. In the process for the optical fiber section, an optical fiber is inserted into a glass tube and fixed by an adhesive agent, and then the glass tube end face is polished, this together with the fiber end. Indium-tin oxide is sputtered onto the glass tube end. Finally, the sensor is assembled. 5 refs., 4 figs., 1 tab.

    The aim is to develop a method of processing oxygen concentration distribution in human organs into an image by computed tomography using near infrared rays capable of transmitting through living tissues. Since the photoabsorption spectra of hemoglobin etc. in blood vary according to the degree of their oxidation, an oxygen concentration level is determined by measuring the magnitude of the variation. In the imaging method named in the title, the object is irradiated with picosecond-level near infrared pulses from all directions successively, the pulses after transmission through the object are measured at all directions at a picosecond-level time resolution, and the distribution of pulse scattering and absorption characteristics are subjected to algorithmic calculation, the outcome is converted into oxygen concentration levels, and an image is obtained. A 64-channel time resolution measurement system is constructed, and is applied to living tissue models (phantoms) and animals, and an image is obtained and evaluated. On the basis of the result, a patient is examined for clinical evaluation, and an image reflecting the distribution of variations in hemoglobin oxygen concentration is obtained for the head of the adult patient. A spatial resolution of 1cm is achieved in case of a phantom 10cm in diameter. In the case of 64 channels, measurement takes approximately 20 minutes and mapping image data measurement takes approximately 7 minutes. (NEDO)

    Experiment was made on removal of NOx from ambient air using ceramic blocks coated with a newly developed easy-to- handle TiO2 film photocatalyst. After TiO2 sol was prepared by hydrolyzing titanium tetraisopropoxide, the photocatalytic blocks were prepared through drying and sintering after immersing the blocks in TiO2 sol. The effect of the number of coating on catalytic performance was studied using the single-coated and triple-coated blocks. Artificial solar light of 1mW/cm{sup 2} was used as light source for flowing reaction experiment of air (containing NOx) in a laboratory. NOx concentration rapidly decreased with irradiation, and 94% and 98% of NOx were removed by the single- and triple-coated blocks, respectively. NOx was completely oxidized to HNO3 through NO2 by triple-coated blocks. The demonstration test of removal of NOx from ambient air in Okazaki city showed a removal rate of nearly 90% in noonday and 40% or more in average, while not 0% but 5-20% even in the nighttime. The latter is probably derived from adsorption by the porous photocatalytic blocks. 2 figs., 4 tabs.

    Experimental studies have been carried out on suppressing early deterioration in amorphous silicon solar cells. The amorphous silicon solar cell is characterized by deterioration due to light irradiation and restoration due to temperature rise. An exposure experiment was performed under three conditions: installation in natural environment, installation with rear side of the solar cells covered with an insulating material, and installation with rear side of the solar cells covered with warming elements and an insulating material. Tests were made on suppressing progress of the early deterioration caused by temperature conditions. As a result, the efficiency in the natural condition was found to decrease as largely as 32% in an open circuit condition and 58% in a short circuit condition. The efficiency reduction rate was smaller in the open circuit condition when the insulation material was installed, but in the short circuit condition, resistance characteristics caused by rain water and electrolytic corrosion were exhibited. For the case with warming elements installed, the reduction in the efficiency was more remarkable, contrary to the expectation. The cause was determined that water existing between the rear side and the warming elements was warmed up, accelerating the electrolytic action, and resulting in deterioration advanced over a wide area in the rear side. 6 refs., 6 figs., 3 tabs.

    Plants higher than Cyanobacterium have two kinds of resction centers(RC) which convert photon energy to a flow of electrons and whose photosensitive spectral regions are slightly deviated from each other. In the photosynthetic process, the ratio of numbers between these two kinds of reaction centers is adaptively varied so as to allow the overall flow of electrons to proceed in a well-balanced manner. It is important to rapidly and exactly determine the ratio of RC numbers between the two photochemical systems in order to investigate such photoadaptive process. The report describes the quantitative determination using high performance liquid chromatography(HPLC) for this purpose. Pigments were extracted from Cyanobacteria which are in different adaptive processes brought by being cultured in the environments differing in the quantity of light or in the environment of varying quantity of light, and subjected to quantitave determination in consideration of the fact that the reaction centers, I and II, have the respective special kinds of chlorophyl derivatives Chl-a, Chl-a{prime}. As the results, it was confirmed that validity can be given to the estimation of the numbers of reaction centers in terms of the quantities of Chl-a and Chl-a prime and the proposed method is drastically faster and simpler than the conventional methods. 14 refs., 5 figs..

    This paper describes a proposed method for suppressing light deterioration (temperature effect method), in which an annealing effect was always expected by laminating an NEM element and a heat insulation material on the back side of a-Si solar cell module and thereby raising the temperature in the back side of the module, and also describes an outdoor exposure test device completed for the method. The NEM element consisted of conductive potassium titanate and high molecular polymer and was a self temperature-controlling organic exothermic body that required no outside temperature control device. It was provided with a heat generating temperature of 45-75{degree}C as the exothermic property of the element and capable of generating heating temperature arbitrarily according to the purpose. The NEM element varied a resistance value against the ambient temperature and kept the element temperature constant. Measurement was commenced starting April 19, 1996, using the completed outdoor exposure test device and a measuring circuit. The deterioration phenomenon was and from then on continuously examined under the following conditions: (1) measurements were those of clear days only, and (2) measurements to be used were those between 10:00 and 14:00 with the quantity of solar radiation on a constant level. 4 refs., 4 figs., 1 tab.

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

    The composite panel with photovoltaic-thermo module becomes higher in energy-saving than the conventional air-conditioning system by the independent radiational heating and cooling effect obtained when the generating panel using a solar cell module is combined with the heating and cooling panel using a thermo-element module. The output of a solar cell module can be directly used because the solar cell module operates in AC. This paper reports the relation between the absorbed value and power consumption of the cooling panel, while paying attention to the cooling panel. The performance coefficient of the maximum absorbed value from an non-absorbing substance to a cooling panel is 2 to 3. Assume that the cooling panel during non-adiabatic operation is operated using a solar cell module of 800 W/m{sup 2} in solar intensity and 15% in conversion efficiency. The cooling-surface temperature difference is 12.12 K, and the maximum absorbed value of a non-absorbing substance to a cooling panel is 39.12 W/m{sup 2}. The absorbed value of the outer temperature to the cooling panel is 74.4 W/m{sup 2}, and each performance coefficient is 3.26 and 0.62. The absorbed value must be calculated for evaluation from the cooling-surface temperature difference measured directly from the cooling panel. 4 refs., 8 figs., 1 tab.

    This paper summarizes application of photo-catalysts in environmental problems. The paper lists examples of the application in residential environments. Photo-catalytic decomposition is possible by using ultraviolet rays contained in room illumination if the bacterial presence is sparse. The examples thereof may be cited as follows: if colon bacilli are suspended on a tile with TiO2 photo-catalyst sintered in it and exposed to room illumination, the bacteria are disinfected; using photo-catalysts in a bathroom suppresses deposition of Pseudomonas aeruginosa; a photo-catalyst tile (TiO2 loaded with Cu) and light irradiation reduce intensity of tobacco smoke odor; and adsorbents may be used simultaneously if intermediate products are odor generating substances. The examples of applying photo-catalysts to regional environments may be quoted as follows: growth of algae in a Petri dish is suppressed by presence of Cu loaded TiO2 under room illumination; this leads to an expectation on its effect in a relatively clean water environment; glass beads loaded with a TiO2 photo-catalyst placed in a gold fish breeding tank reduces turbidity, the number of colon bacilluses, and COD value; and the mortality in gold fish shows no change. With an objective of application to exterior building materials, photo-catalyst applied tiles were left outdoors for 160 days. Nitric acid ions were detected that are thought to have been generated by decomposition of microorganisms that have deposited on the tiles. 6 refs., 5 figs., 3 tabs.

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

    The measurement by an interference method at the tip of fast propagating cracks was investigated. To clarify the direction-dependent problem of dynamic cracks in a higher-order term, a high-precision stress field must be measured in every direction. In this method, the propagated interference fringes near the crack tip are shot at a speed of some hundreds of m/sec, and the coefficient of dynamic stress extension is obtained from the expression given when the number of fringes (`m`) in the interferences fringes is differentiated partially. The information below was obtained. The stress field in every direction can be analyzed by the interference method. However, the interference fringes in an area of absolute {theta} < 120{degree} are radially spread from the crack tip, so the precision of the interference fringes in the {gamma} direction deteriorates. In this area, the above partial differential is higher in precision when {alpha}m/{alpha}{theta} is used instead of {alpha}m/{alpha}{gamma}. The stress extension coefficient obtained by a caustic method can be verified if a stress field of {theta} = {plus_minus}72{degree} is analyzed by the interference method. By shooting in this optical system, the COD measurement, the K-value measurement of caustic light, and the stress field measurement by an interference method can be done simultaneously. 17 refs., 11 figs.

    Purpose of this research are (1) development of photocatalysts which selectively drive hydride transfer and (2) their application to the enantioselective reduction of an unsaturated substrate. photocatalysis of [Ru(bpy){sub 2}(py){sub 2}]{sup 2+} (1) and [Ru(tpy)(bpy)(py)]{sup 2+} (2) (bpy=2,2'-bipyridine, tpy=2,2' : 6',2' '-terpyridine, py=pyridine) for reduction of unsaturated compounds was investigated using triethylamine as a reductant. Formation of the hydrogenated compounds was observed but the corresponding one electron reduced compounds were not detected at all. The complex 1 photocatalysed the reduction of trifluoroacetophenone (5) and gave the alcohol in a 67% yield but 2 gave only a 27% yield. The reaction proceeds via the photosubstitution of a py ligand of the ruthenium complex, followed by photochemical formation of the hydride complex. The ruthenium hydride complex reacts with 5 to give [Ru(tpy)(bpy)(OCHPhCF{sub 3})]{sup +} (4). Dissociation of 4 to the alcohol was not efficient and the yield was 10%. (author)

    The present paper proposes a new taste recognition system using optical response patterns from multi-channel optical fiber sensors having potential sensitive dye coatings. It was found that the sensors give large changes in optical absorption spectra of the dyes when they are immersed in various taste solutions. Consequently, it was shown that the sensors can be used as a taste sensor. Six dyes, which give large changes in dye absorption, were selected from twenty dyes and used for six-channel optical fiber taste sensors array. The absorption spectra change data were processed by multiple discriminant analysis and neural networks using back-propagation algorithm. From the analytical results, it was demonstrated that salty (NaCl), bitter (quinidine), sweet (sucrose), sour (HCl), and umami (sodium glutamate) substances can be recognized from each other by using the optical taste sensor system. 11 refs., 8 figs., 2 tabs.

    Properties of the active gasification catalysts prepared by ion exchange reaction of CaCO3 and coal were studied. Several kinds of Ca-loaded coal specimens were prepared to compare their properties among them by physically mixing coal particles with CaCO3 ones in air, by kneading both materials in pure water while crashing and by impregnating CaCO3 into coal while agitating them in pure water. Although Ca-loading onto the impregnated specimen was nearly one-half that of the kneaded one, its catalysis was equal to the kneaded one. CaCO3 greatly accelerated steam gasification only by mixing it with low rank coal in water, and such a high catalytic activity was caused by ion-exchanged Ca produced by the reaction between CaCO3 and COOH radical in coal. Aragonite of seashells yielded more Ca-loading than calcite of limestone, suggesting one of the useful treatment of seashell waste. 3 refs., 4 figs., 2 tabs.

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

    To investigate the behavior of coal liquefaction reaction in early stage as a part of studies on the coal liquefaction characteristics using NEDOL process 1 t/d process supporting unit (PSU), coal slurry sample was taken from the outlet of slurry preheater located in the upflow of liquefaction reactors, and was tested. Tanito Harum coal was used for liquefaction. Preheater was operated under the condition of pressure of 170 kg/cm{sup 2}, gas flow rate of 64 Nm{sup 3}/hr, and at temperature up to 410{degree}C at the outlet, in response to the standard test condition. The slurry sample was discharged into a high temperature separator with temperature of 250{degree}C. Liquefaction was not proceeded at the outlet of preheater. Solid residue yielded around 80%, and liquid yielded around 15%. Gases, CO and CO2, and water yielded also small amount around 3%. The solid sample contained much IOM fraction (tetrahydrofuran-insoluble and ash), and the liquid contained much heavy oil fraction. Hydrogenation was not proceeded, and the hydrogen consumption was very low showing below one-tenth of that at the usual operation. Hydrogen sulfide gas was formed at early stage, which suggested that the change of iron sulfide catalyst occur at early stage of liquefaction. 1 ref., 5 figs., 2 tabs.

    The purpose of this study is to prevent the deactivation of catalysts recycled in the 0.1 t/d bench scale unit (BSU). Catalysts recovered during reactions in the BSU and after reactions in the 5-liter autoclave were analyzed, to investigate the influences of the reaction condition on the property and activity of catalysts. Were used {gamma}-iron oxyhydroxide ({gamma}-FeOOH), {alpha}-iron oxyhydroxide ({alpha}-FeOOH), and natural pyrite (FeS2) as catalysts. At the S/Fe atomic ration of 1.2 under the BSU reaction condition, troilite was more easily formed from {gamma}-FeOOH compared with pyrite and {alpha}-FeOOH. As the reaction proceeded through the first, second, and third reactors, the crystal size increased, the pyrrhotite content decreased, and the troilite content increased. Deactivation due to the formation of troilite was irreversible. At the S/Fe of 3.0, however, both the formation of troilite and the crystal growth of pyrrhotite were not observed. It was found that the deactivation of catalysts can be remarkably suppressed. 5 refs., 6 figs., 1 tab.

    The NiMo sulfide supported on Ketjen Black (KB) was more effective and yielded lighter oil products containing light fractions with their boiling point below 300{degree}C during the two stage liquefaction combining low temperature and high temperature hydrogenation the conventional NiMo/alumina catalyst and FeS2 catalyst. Although the NiMo/alumina yielded increased oil products during the two stage liquefaction, the lighter oil fractions did not increase and the heavier fractions increased mainly. This suggests that the hydrogenation of aromatic rings and successive cleavage of the rings are necessary for producing the light oil, which is derived from the sufficient hydrogenation of aromatic rings using catalysts. For the two stage reaction with NiMo/KB catalyst, it was considered that sufficient hydrogen was directly transferred to coal molecules at the first stage of the low temperature reaction, which promoted the solubilization of coal and the successive hydrogenation at the high temperature reaction. Thus, high activity of the catalyst must be obtained. It is expected that further high quality distillates can be produced through the optimization of catalysts and solvents at the two stage reaction. 1 ref., 4 figs., 1 tab.

    With relation to the coals delivered as common samples in the coal fundamental technology development project, an experimental study was conducted on agglomeration characteristics and reaction characteristics in the fluidized-bed coal gasifier. For the experiment, used was a fluidized bed gasifier inserted with a cone-shape dispersion plate with a nozzle in the center. After raising the temperature of the gasifier up to 773K, gasification was conducted sending to the gasifier air from the nozzle and steam from the dispersion plate. The mean particle diameter and gas concentration of chars were measured till the temperature reaches 1373K. As a result of the experiment, it was confirmed that the carbon conversion ratio increases with a decrease in coalification degree of the coal. Moreover, influence of the coal kind was markedly observed at the grid zone of the lower part of the bed, and it was clarified that the lower carbon content ratio the coal kind has, the faster the speed of CO formation and water gasification get. The agglomeration temperature of charcoal which is a product of the condensate is lower by as many as several hundred K than the point of softening, and it was considered to be necessary to study the relation with the temperature distribution in the bed. 3 refs., 3 figs., 1 tab.

    The liquefaction reaction system of an NEDOL process coal liquefaction 1t/d PSU was opened and checked to investigate the cause of the rise of differential pressure between liquefaction reactors of the PSU. The liquefaction test at a coal concentration of 50 wt% using Tanito Harum coal was conducted, and it was found that the differential pressure between reactors was on the increase. By the two-phase flow pressure loss method, deposition thickness of deposit in pipelines was estimated at 4.4mm at the time of end operation, which agreed with a measuring value obtained from a {gamma} ray. The rise of differential pressure was caused by deposit formation in pipelines connecting reactors. The main component of the deposit is calcite (CaCO3 60-70%) and is the same as the usual one. It is also the same type as the deposit on the reactor wall. Ca in coal ash is concerned with this. To withdraw solid matters deposited in the reactor, there are installed pipelines for the withdrawal at the reactor bottom. The solid matters are regularly purged by reverse gas for prevention of clogging. As the frequency of purge increases, the deposit at the reactor bottom decreases, but the deposit attaches strongly to pipelines connecting reactors. It is presumed that this deposit is what Ca to be discharged out of the system as a form of deposition solid matter naturally in the Ca balance precipitated as calcite in the pipeline connecting the reactor. 3 refs., 5 figs., 4 tabs.

    In this paper, bond cleavage reactions are discussed in relation to the softening and solubilization of coal. Were used 9,10-dihydroanthracene (DHA) and 9,10-dihydrophenanthrene (DHP) as models of hydrogen donating compounds in coal, and bibenzyl, 1,2-diethane, benzylphenylether, and 1,5-dibenzylnaphthalene were used as models of bridge structure compounds. They were compared mutually, as to reactivity of coal against DHA and DHP. For the homolytic cleavage of bridges, DHA with excellent radical supplement performance provided excellent hydrogen donating performance. While, for the ipso-position cleavage of bridges, it was found that DHP can act as an effective hydrogen donor. For the reaction between coal and hydrogenated aromatic compounds, cleavage of relatively weak bonds, such as ether linkage and dimethylene linkage, occurred at about 380{degree}C, and hydrogen from DHA or DHP was consumed. On the other hand, the results suggested that the cleavage reaction at ipso-position affected by hydrogen donating solvent is also important at temperature range around 420{degree}C. 2 refs., 3 figs., 1 tab.

    Recently, taste and bioactivation of large number of oligopeptide become clear, and the development of the efficient synthetic method becomes the urgency. In the production process by conventional enzyme reaction which combined the crystallization, because the solubility of the product to the water which is reaction solvent is low, the yield remained at about 60%, and the problem of reaction inhibition of the product by the crystal had also been indicated. In the enzyme synthesis of the aspartame in which he is the representative oligopeptide, it aimed at the establishment of the new synthesis method which can improve yield and reaction rate, while the segregation enzyme was continuously utilized. In this synthetic method, supply of organic solvent which dissolved the substrate, extraction of the substrate from organic solvent to water phase, synthesis reaction by the segregation enzyme in water phase, extraction of the aspartame which is a product from water phase to organic solvent progress, and they continuously progress by one complete mixing reactor. The process which controlled these speeds and yields was quantitatively analyzed, and material balance style considering substrate, enzyme and mass transfer of the product and enzyme reaction speed was deduced. The optimum operating condition for improving yield and productivity of the purpose product using this solution was examined, and optimum supply concentration and agitation speed of aspartic acid which was a substrate were started, and the optimum operating condition which realizes the improvement in high yield and productivity over 90% of the aspartame was clarified. Like this, it is that this research adopts features of liquid Citrus nobilis two-phase partition for the enzyme synthesis of the aspartame, and it is considered that there is a value, because it is the creative research which verified that the productivity can be greatly improved by the utilization of the chemical-engineering technique, and because the industrial contribution is also big.

    In order to structure a chemical reaction process that does not discharge a large amount of waste by-products or harmful chemical substances, or so-called environment friendly process, investigations and discussions were given based on the results derived in the previous fiscal year. A proposal was made to reduce environmental load on development of oxidized and dehydrogenated catalysts that can produce selectively ethylene, propylene and isobutylene in an oxidation process. In liquid phase oxidation, redox-based oxidation and solid catalyzation of automatic oxidation reaction were enumerated. In acid base catalyst reaction, development of ultra strong solid acid was described to structure no pollution discharging process. In the fine chemical and pharmaceutical fields, the optical active substance method and the position-selective aromatics displacement reaction were evaluated to reduce environmental load. A questionnaire survey performed on major chemical corporations inside and outside the country revealed the following processes as the ones that can cause hidden environmental problems: processes discharging large amount of wastes, processes treating dangerous materials, and processes consuming large amount of energy. Development of catalysts is important that can realize high yield, high selectivity and reactions under mild conditions as a future environment harmonizing chemical process. 117 refs., 23 figs., 22 tabs.

    The baking process in cement production means the process that the raw materials which were mixed and pulverized in the raw material preparation process are charged into a reaction furnace which is called kiln, and clinders (intermediate product of cement) are generated. It is the process which affects quality as well as production cost of cement more significantly than anything else. In this article, an outline of the above baking facilities, how the raw materials change and clinkers are generated therein, and how they are controlled are introduced. Clinkers are composed of such products as alite, belite, aluminate and ferrite, etc. which were generated after decomposition reactions of such raw materials as lime stone, clay, silica rock and iron oxide in the above kiln. The essential ponts of the process control which makes the generation reactions of clinker compounds efficiently are such two points as well balanced raw materials to be charged into the baking facilities and stable operation of such facilities. The quality of cement which is required as finished goods is achieved by the quality control at each intermediate process and the quality tests of cement. 5 refs., 10 figs., 2 tabs.

    Ring-opening of heteroaromatics and heteroatom-removal reaction were studied experimentally using the acidic catalyst containing phosphoric acid for improvement of an upgrading method of coal derived oils. In experiment, some Ru-carrying metal oxide catalysts such as RMZ, RML and RMN catalyst, and MNP catalyst containing phosphoric acid were used as specimens. Nuclear hydrogenation reaction and hydro-denitrogenation reaction of dibenzothiophene and carbazole were compared with each other. The experimental results are as follows. Both RMN and RMNP catalysts offer a superior selectivity in nuclear hydrogenation reaction and hydro-denitrogenation reaction of carbazole. Although both catalysts offer an extremely high nuclear hydrogenation activity at 360{degree}C, these offer the high selectivity of denitrogenation products at 430{degree}C. In comparison of the activities of MN and MNP catalysts with the same Mn2O3:NiO ratio, MNP catalyst offers the higher denitrogenation activity than MN catalyst at 430{degree}C. 1 ref., 3 tabs.

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

    This paper describes the results of the experiment in which crystallization of protein of reactive center purified from the photosynthetic film of thermophilic purple sulfur photosynthetic bacterium Chromatium tepidum whose hyrogen donor in photosynthesis is H2S instead of H2O was attempted. Crystallization was carried out by the vapor diffusion method and particularly by using ethylene glycol as precipitator at 4[degree]C after various investigations on the conditions of crystallization. By X-ray diffraction, this crystal was found to belong to the rhombic system, and it was estimated that the lattice constants, a, b, c equal to 140[angstrom], 190[angstrom] and 80[angstrom] respectively. This bacterium is a thermophilic bacterium having the optimum growth temperature of 48-50 [degree]C and utilizes CO2 or H2CO3 as corbon source, ammonium, urea etc. as nitrogen source and thiosulfate as sulfur source. Moreover, another purpose of this investigation was to determine the thermophilic location by elucidating its configuration (although, as a result, the analysis of configuration had no sufficient resolution). It was confirmed that the enzyme system of photosynthetic film and its cytoplasm obtained by ultrasonic spallation of this cell have CO2 fixing activity utilizing light energy. 23 refs., 14 figs., 3 tabs.

    The purpose of this study was to investigate a traffic environment that can reduce traffic accidents of elder walker. We focused on the relationship between traffic accidents and elder person`s spatial attention. In this paper, an adolescent subject`s and an elder subject`s pointing movement to a visual target was measured in three conditions. Condition 1: Only target was presented. Condition 2: Auditory stimulation was added at a location the same distance from the center as that of the targets but in the opposite direction. Condition 3: Auditory stimulation was added at the same location as the target. The targets were placed in extra working space with the distance of 1.5 meter from a subject to the targets. In adolescent subjects, results showed that in Condition 3, latency was shorter and the error rate of pointing movements was lower than in the other conditions. In elder subjects, results showed that in all Conditions, ignore ratio to peripheral targets is higher than adolescent subjects. Nevertheless, in condition 3, ignore ratio was lower than in the other conditions. These results suggest that, it is possible to draw elder walker`s spatial attention and to control spatial attention by auditory stimulation. 13 refs., 6 figs., 1 tab.

    Experiment was made on stereo-selective hydrolytic reaction of trifluoroethyl ester of ketoprophene by various kinds of lipase. In addition, study was made on the stability of lipase simply immobilized on porous ceramics under the existence of organic solvent. In the experiment, the hydrolytic activity of 8 kinds of lipase was studied for ketoprophene monochloroethyl ester (1a) and trifluoroethyl ester (1b). The experiment result showed that lipase M originating in mold (Mucor Javanicus) shows a high reactivity and stereo-selectivity for the compound (1a). The lipase immobilized on porous ceramics was easily obtained by a very simple method composed of only throwing carriers into enzyme suspension, agitation and refrigerated drying. The lipase immobilized on porous ceramics 'Toyonite 200-A' synthesized from kaolinite retained the residual activity of nearly 50%, original selectivity and considerable stability after 5 times of repetitive uses. This study result is useful for bio- reactors and bio-sensors for synthesis or decomposition of compounds. (NEDO)

    With the purpose of converting solar heat energy to industrial heat energy, an experiment of acetone hydrogenation was carried out using a heat exchanger type reactor that recovers heat generated by acetone hydrogenation, an exothermic reaction, and supplies it to an outside load. In the experiment, a pellet-like activated carbon-supported ruthenium catalyst was used for the acetone hydrogenation with hydrogen and acetone supplied to the catalyst layer at a space velocity of 400-1,200 or so. In the external pipe of the double-pipe type reactor, a heating medium oil was circulated in parallel with the flow of the reactant, with the heat of reaction recovered that was generated from the acetone hydrogenation. In this experiment, an 1wt%Ru/C catalyst and a 5wt%Ru/C catalyst were used so as to examine the effects of variation in the space velocity. As a result, from the viewpoint of recovering the heat of reaction, it was found desirable to increase the reaction speed by raising catalytic density and also to supply the reactant downstream inside the reaction pipe by increasing the space velocity. 1 ref., 6 figs., 1 tab.

    Reactions of various model compounds were investigated using synthetic pyrites for coal liquefaction. In this study, successive changes of the catalysts were investigated from the reactions of model compounds by using three different synthetic pyrites with the lapse of time after production. Benzyl phenyl ether, dibenzyl, and n-octylbenzene were used as model compounds. Reactions were conducted in an autoclave, into which sample, catalyst, decalin as solvent, and initial hydrogen pressure 10 MPa were charged. The autoclave was held at 450 or 475{degree}C of reaction temperature for 1 hour. The catalyst with a shorter lapse of time after production acted to hydrogen transfer, and inhibited the formation of condensation products due to the stabilization of decomposed fragment. It also acted to isomerization of materials by cutting alkyl side chains. When adding sulfur to the catalyst with longer lapse of time after production under these reaction conditions, it inhibited the formation of condensation products for the reaction of benzyl phenyl ether. However, it did not provide the effect for the reaction of n-octylbenzene. 5 refs., 3 figs.

    With an objective to evaluate effects of clayish minerals in the electric and electromagnetic exploration methods, resistivities were measured on samples which have adjusted contents of clayish minerals. Samples were prepared for an experiment by mixing 300 g of glass beads having a diameter of about 1 mm, 200 g of aqueous solutions, and 3 to 90 g of smectites. The aqueous solutions used KCL, NaCL and CaCL2 at concentrations of 0.1 to 0.001 mol/L. The result of the experiment may be summarized as follows: among the three kinds of smectites, KN-1 has the greatest effect to reduce the resistivity; the resistivity decreases when the smectite amount is increased except when the concentration of the solution is high; this phenomenon is thought to be caused by increase in the region of an electrically doubled layer which has higher ion concentration; change in the resistivity increases when the solution concentration is low, and decreases when the concentration is high; and in the case of the solution concentration being 0.1 mol/L, the resistivity increases with increase in the smectite content. 5 refs., 7 figs., 1 tab.

    To study the utilization of the photochemical sterilization of thermoduric bacterial spores B. stearothermophilus with photocatalysis of TiO2 particles, light irradiation experiments are conducted under various operational conditions. TiO2 particles and dissolved oxygen resulting from aeration must coexist to accelerate the rate of spore sterilization under light irradiation of a high pressure mercury lamp. The sterilization rate increases with larger average light intensity in the reactor, and it is estimated that the dissolved oxygen contributes to the formation of oxidative radicals which become the attacking species. The maximal rate of spore sterilization is obtained under the condition of TiO2 concentration of 5[times]10[sup -2]kg[center dot]m[sup -3]. By combining a second-order rate equation, wherein the spores' death caused by the oxidative radicals formed by TiO2 photocatalysis is taken into consideration, and single-hit multitarget model, wherein the target damaged by the oxidizer in the spores is assumed, the sterilization velocity can be described well, and the effect of light intensity and the obtained rate parameters are correlated well. 13 refs., 7 figs., 3 tabs.

    To establish the pressure dependence of silent discharge excited rare gas excimer light emission, a vacua ultraviolet light was subjected to spectroscopic analysis at a pressure lower than 20kPa. Researches are under way to apply the discharge excited rare gas excimer lamp as a vacuum ultraviolet light source for the development of new materials and for the conservation of environments. When the pressure is as low as 1.8kPa or 4.4kPa, the emission has peaks at wavelengths centering on 147nm and 149nm, both of which are the resonance lines of the xenon atom. Excimer generation becomes prominent as the pressure increases, with the second continuum of light growing dominant at 35kPa to weaken relatively the resonance lines and the first continuum of light. In the first continuum, emission increases only at a suppressed rate, as compared with emission in the second continuum, due for instance to a collision caused relaxation process in which excimers are lost. In the case of xenon in the vicinity of 10-11kPa, the first continuum of light and the second continuum of light are approximately equal in emission intensity, producing a vacuum ultraviolet light source with a bandwidth relatively large for a single gas spectrum. 14 refs., 11 figs.

    The unique advantage of the pulsed laser deposition is its ability to produce highly oriented stoichiometric films at a low substrate temperature. Ferroelectric PbTiO3 thin films have been formed using 2nd laser assisted laser ablaion technique at low temperature, i.e., 350degC, on Sr7iO3 single-crystal substrates and Pt/MgO electrodes. The second laser irradiation at the substrate surface is quite effective for crystallization of the films at low substrate temperature below 400degC. The suitable energy density (fluence) of the irradiation laser is in the range of 30-100 mJ/cm{sup 2}. X-ray diffraction patterns of PbTiO3 thin films show c-axis orientation, with a rocking angle of 1.0 - 0.5deg. These films exhibit ferroelectric hysteresis loop. The dielectric constant and remanent polalyzation of the PbTiO3 films are in the range of 120-150 and 60-80 {mu}C/cm{sup 2}, respectively. 31 refs., 10 figs., 1 tab.

    In order to clarify plant body potential information, study was made on a leaf surface potential response to light irradiation. The leaf surface potential change, total transpiration and transpiration rate of Ficus Elastica were measured using light irradiation period and room temperature as parameters. The leaf surface potential change shows a positive peak after the start of light irradiation, while a negative peak after its end. Arrival time to both peaks is constant regardless of the light irradiation period, while decrease with an increase in room temperature. Although the total transpiration increases with room temperature, this tendency disappears with an increase in light irradiation period. The transpiration rate shows its peak after the start of light irradiation. Arrival time to the peak is saturated with the light irradiation period of 60min, while decreases with an increase in room temperature. These results suggest that opening of stomata becomes active with an increase in room temperature, and the peak of the leaf surface potential after the start of light irradiation relates to the opening. 3 refs., 11 figs.

    In calculating heat balance of solar pond, calculation was made considering things except quality of the incident ray and physical properties of pond water which were conventionally considered. The real optical path length was determined from the reflection ratio of ray on the water surface based on the refraction ratio of pond water and the locus of water transmitted ray in order to calculate a total transmission rate. The rate of absorption of monochromatic lights composing of solar light in their going through the media is different by wavelength, and therefore, calculation was made in each monochromatic light. As to four kinds of salt water solution, NaCl, KCl, MgCl2 and CaCl2, these phenomena seen in solar pond are taken in, and a total transmission rate based on reality can be calculated by the wavelength integration method. Moreover, in the salt gradient layer, there are gradients in both concentration and temperature, and thermal physical values of each layer change. Accordingly, mass transfer and thermal transfer by both gradients were considered at the same time. An analytic solution was introduced which analyzes salt diffusion in the temperature field in the gradient layer and determines the concentration distribution. By these, concentration and physical values of each layer were calculated according to phenomena, and thermal balance of each layer of the solar pond was able to be accurately calculated. 6 refs., 5 figs., 2 tabs.

    The results achieved in fiscal 1992-1995 under the above-named project are stated. In the development of photocatalytic materials, a photocatalytic fluorocarbon polymer sheet suitable for use in a denitration apparatus is developed. A high density fluorocarbon polymer sheet composed of TiO{sub 2} modified with 0.3% of Pd/absorbent zeolite/fluorocarbon polymer PTFE (polytetrafluoroethylene) =48-63/24-36/10-20 is fabricated, which achieves a level higher than the denitration goal of 70%. Although the sheet in a 500-hour accelerated exposure test undergoes a hardening phenomenon in which elasticity decreases and tensile strength increases, yet degradation is hardly detected. Although a slight reduction is detected in denitration efficiency, yet it does not affect its practical application, and thus the durability goal is achieved. In the development of an energy conservation type air cleaning apparatus usable in underground parking areas or motorway tunnels, an apparatus capable of treating air at a rate of 2,000m{sup 3}/hour is fabricated, and this achieves a denitration level of not less than 80% in a field test (in the absence of rainfall). For denitration in the presence of rainfall, the apparatus is combined with an equimolar adsorption system, and a system capable of 80% denitration is proposed on the basis of data actually measured for each of the two. A conceptual design for a service model comprising a photodenitration and equimolar adsorption systems is evaluated, and it is found that it occupies less space than the existing models. (NEDO)

    A large number of single mode fibers (SMF) for 1.3 {mu}m light are installed in electric power communication facilities. On the other hand, light of 1.5 {mu}m band is being used more in the capacity increasing technology to minimize transmission loss. If this is applied to the current SMF, waveform distortion is generated due to wavelength dispersion, thus the transmission speed and distance are limited. In order to evaluate quantitatively the effects of a wavelength dispersion compensating technology, a method was developed to derive time change in each wavelength component in light pulse. No sufficient wavelength separation is possible if permeation bandwidth of a wavelength filter is wider than the wavelength width of the light pulse. Therefore, a method was developed to derive time change in the wavelength components in the light pulse from small difference in the measured light waveforms after transmission when the central wavelength of a wavelength variable filter is varied. It was possible from comparing the method to derive the wavelength dispersion amount and the dispersion compensation amount. Since the method reveals simultaneously the distribution of strength against wavelength and time contained in light pulse, the method is advantageous in elucidating compensation limit and causes for compensation errors. The effectiveness of the method was verified by a 1.5-{mu}m light transmission test. 14 refs., 26 figs., 2 tabs.

    Pursuant to the measuring of temperature dependency of the characteristics such as conversion efficiency, during the process of degradation in a-Si solar cells due to light and electric current and the process of recovery by annealing, this paper describes changes in temperature coefficients, correlation between the characteristic parameters and the degradation, and the results of the examination of their characteristics. The conversion efficiency {mu} degraded approximately by 45% of the initial value each by the irradiation under a light intensity with 3 SUN accelerated and by the infusion of current at 20mA/cm{sup 2}; and then, the efficiency recovered to 70-75% of the degradation by subsequent annealing. In addition, in the temperature dependency at 80{degree}C against at 20{degree}C, Isc slightly increased while Vcc greatly decreased. This slight increase in Isc was mainly due to the decrease in the width of the forbidden band, while the decrease in Vcc was due to the increase in the reverse saturation current. The temperature dependency of {mu}N was negative, becoming small in accordance with the degradation. The temperature dependency of FF/FFO was negative initially both in light and current, but it decreased with the degradation and turned to positive. The temperature coefficients of I-V parameters reversibly changed corresponding to the degradation and recovery of these parameters and stayed in a good correlation. 7 refs., 8 figs., 1 tab.

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

    The removal treatment of free cyanide in waste water was tested by complexation with Fe(2) ion followed by alkaline chlorination and precipitation of residual iron cyano complex to study saving of sodium hypochlorite (NaClO) for alkaline chlorination. The complexation with Fe(2) ion was studied in batch treatment under the coexistence with zinc ion assuming plating waste water, while the relation between the complexation and effective chlorine consumption in alkaline chlorination was studied in continuous treatment. As a result, the effective chlorine consumption was greatly decreased by pretreatment, and a cyanic acid ion (CNO{sup {minus}}) concentration was also lower than that in conventional methods. In the case of free cyanide with lower initial concentration, the total cyanide concentration in final treated water offered sufficiently low values only by adding zinc salt, while in higher initial concentration, it reached 1 ppm or less through precipitation by adding a reductant together with zinc salt. 9 refs., 7 figs., 2 tabs.

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

    This paper discusses effects of surface reaction on deactivation of excited molecular oxygen in {sup 1}{Delta}g condition. Gaseous oxygen containing excited oxygen generated by microwave discharge at a concentration of less than 1% is flown into several kinds of tubes to be measured such as quartz tubes (with an inner diameter of about 10 mm), and the light emitting intensity of the excited oxygen was measured upstream and downstream of the tubes to be measured (with in-tube pressure of 1 Torr or 2 Torr) to derive its concentration change. The surface reaction on the tube wall was regarded as a primary reaction, and the concentration change of the excited oxygen in flows in the round tube (attributable to the surface reaction) was analyzed. With respect to effects of tube wall materials on deactivation of the excited molecular oxygen, the surface deactivation probability in the case of using low-activity materials has decreased in the order of Pyrex, PVC, quartz, PFA and PTFE. The surface deactivation probability in the case of using a metallic material, SUS316L, was about 1000 times larger than that in the quartz. 14 refs., 7 figs., 1 tab.

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

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

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

    In polymerization involving a rapid exothermic reaction, it is necessary for the generated heat in this operation to be removed from the reactor by a cooling coil or jacket to control the reaction temperature. But, fluid in the reactor is gets stagnant as the reaction proceeds, because the viscosity is increasing due to monomer convection, therefore the reactor often has induced uneven temperature distribution. In this work, radical addition polymerization was carried out in a reactor using several types of impeller-paddle, anchor, helical screw and helical ribbon, Under these conditions, local temperature distribution was measured in detail using our prototype real-time and multi-point temperature measuring instrument which is able to measure simultaneously changing temperature at local positions via many thermocouples. As a result of these experiments the condition of changing local temperature and the obtained polymers were found to be related to the type of impellers. We found the high temperature areas in the reactor produced polymers composed of undesirably short chain length molecules. As the cooling condition of the reactor was found by measuring local temperature, we could also find a suitable position for the control sensor of temperature for lowering local higher temperature in the polymerization under the set value. 15 refs., 8 figs., 2 tabs.

    In radical additional solution polymerization, the viscosity increases with reaction progress. It is important to evaluate beforehand the cooling capacity of the reactor, which worsens with the process. In this study, a stirred batch reactor with both a paddle and a helical screw impeller were studied, and measurements were made for the dynamic changes of the film heat transfer coefficient of the cooling coil with progress of the polymer reaction. We found the change could be evaluated by the calculating heat balance of the generated heat, the viscous dissipation energy and the sensible heat change under conditions of monomer conversion and changing viscosity. 11 refs., 7 figs.

    Coal demineralization mechanism and its optimum condition were studied by hydrothermal reaction between Ca(OH)2 and quartz as a coal demineralization model. In experiment, the mixture of powder quartz and Ca(OH)2 water slurry was subjected to reaction in an autoclave under spontaneous pressure at 175-340{degree}C. After dried in N2 gas atmosphere at 105{degree}C, the reaction product was analyzed by X-ray diffraction, thermo-balance and differential thermal analysis. In measurement of quartz conversion, the specimen was analyzed by X-ray diffraction after removal of bound water by heat treatment at 850{degree}C. The mixture of clean coal deashed by NaOH and a fixed amount of quartz was also used as specimen for experiment. As the experimental result, dicalcium silicate hydrate was mainly produced at 175{degree}C, and the product changed into xonotlite through tobermorite by longer treatment at higher temperature. For complete reaction of quartz, heat treatments for 7 and 5 hours at 300 and 400{degree}C were necessary, respectively. 2 refs., 2 figs., 2 tabs.

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

    A solar chemical heat pump is intended to attempt multi-purposed effective utilization of solar energy by raising low temperature solar heat of about 100 degC to 150 to 200 degC by utilizing chemical reactions. The chemical heat pump under the present study uses a 2-propanol (IPA)/acetone/hydrogen system which can utilize low-temperature solar heat and has large temperature rising degree. It was found from the result of experiments and analyses that IPA dehydrogenation reaction can improve more largely the heat utilization rate in using a falling-liquid film reactor than using a liquid phase suspended system. As an attempt to improve further the heat utilization rate, this paper reports the result of experimental discussions on inclination angles of a reaction vessel and feed liquid flow rate which would affect the fluid condition of the liquid film. As a result of the experiments, the initial deterioration in the catalyst has settled in about 15 hours, and its activity has decreased to about 60% of the initial activity. It was made clear that the influence of the inclination angle of the reaction vessel on the reaction is small. 5 refs., 7 figs.

    This is a prompt report. These days the importance of acquiring knowledge about the structure from the lower crust down to the upper mantle is often discussed with reference taken to Hyogo-ken Nanbu Earthquake. The Hidaka collision belt where the lower crust is exposed on the surface is a rare phenomenon in the world and has been the subject of seismic survey. As a part of the survey, experiments are conducted by the use of vibrations produced by Vibroseis and dynamite sources. Every one of the shot records (20-second record) from the two types of vibration sources contains a clear echo in the vicinity of 16 seconds supposedly from a level deeper than 40 kilometers, not to mention reflections from shallow levels. Although some studies have to be conducted before the reflecting geological boundary (possibly the upper mantle) of the echo near the 16-second point can be identified, yet this is probably the reflection from the deepest level ever obtained in the seismic reflection survey conducted in Japan`s land area. It is proved by this experiment that vibration from a vibrator can reach as far as that from explosion if the vibrator specifications are rightly chosen. 4 refs., 3 figs.

    TiC-TiO{sub 2} composite powders were prepared by in-flight oxidation of titanium carbide powder in RF induction thermal plasmas. Original titanium carbide powder of 20 - 38 {mu}m in particle size was axially injected into the center of argon-oxygen plasma. The powders were partially spheroidized and evaporated through the plasma treatment. X-ray diffraction of plasma-treated powders showed the formation of titanium dioxides, both rutile and anatase phases. The phase content of the plasma-prepared powders strongly depended on the plasma conditions, such as the plasma generating pressure and the oxygen flow rate in plasma generating gas. Especially, the increase of oxygen flow rate in plasma gas gave rise to the increase of heat transfer from plasma to powder particles, exothermic heat of oxidation reaction and cooling rate of plasma, giving the increase of spheroidization ratio, formation ratio of titanium dioxides, and content of anatase phases.

    The reactive sintered compacts of Ti-W-Cr-B mixed powders were manufactured by a pulse electric current technique. Identification and characterization of the resulting boride phase were done using EPMA, XRD and other methods. The density of the sintered compacts rose rapidly with sintering temperature up to 1,773 K, at which temperature the relative density was 94%. Above this temperature, the density rose only slightly with increasing sintering temperature. The borides of Ti and W were synthesized from mixed metal powders by this method. The type of boride formed and its composition depended on sintering temperature. Compacts sintered at lower temperatures consisted of WB{sub 2} and TiB{sub 2} phases, but at the highest sintering temperature, 2,173K, the main phase was (Ti, W, Cr)B{sub 2} solid solution, in which W and Cr were dissolved in TiB{sub 2}. There was also a very small amount of {beta}-(W, Ti, Cr)B phase. By annealing compact sintered at high temperature, the (Ti, W, Cr)B{sub 2} solid solution phase decomposed and the amount decreased.

    An ultrafine iron particle preparing process was developed, which wses gaseous phase pyrolysis in magnetic field of iron pentacarbonyl, Fe(CO){sub 5}, based on the fact that Fe(CO){sub 5} has peculiar characters that its boiling point is as low as 103{degree}C, and starts decomposing in a low temperature zone of 100{degree}C or lower. Vaporizing and introducing into a reactor an fe(CO){sub 5}, andPyrolyzing it at 200-600{degree}C while being diluted with nitrogen and applied with a magnetic field produced uitrafine iron particles of a necklace-like chain comprisinh primary particles having diameter of 15 to 25 nm with 10 to 40 of them linked in a straight chain. It was found that the specific surface area is 30-50 m{sup 2}/g, with the diameter converted from the specific surface area being relatively close to the average diameter obtained from TEM photograph, and that the particle has few pores. Magnetically the iron powder has a coercivity of 123-131 KA/m and a specific saturation magnetization of 120-140 Am{sup 2}/kg, and is expected to be applied as a high density magnetic recording medium. 5 refs.,8 figs., 3 tabs.

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

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

    The molten salt system electrochemical cycle was proposed to reproduce pure Al from scrap Al. The cycle is composed of production of rough AlCl3 by chlorination of scrap Al, refining of rough AlCl3 mainly by sublimation, and electrolytic reproduction of pure Al from refined AlCl3. In production of AlCl3, the Al-Cl2 molten salt system cell composed of anode dissolution reaction of Al and cathode reduction reaction of chlorine gas can generate electric power for the electrolytic reproduction. Chlorine gas can be recycled as anode product. Various experiments were carried out to improve molten salt system cells. In analysis of cell output, voltage drop from open circuit voltage was divided into that due to electrolytic bath resistance, and that due to reaction resistance. The electrolytic bath resistance could be determined from transient characteristics of voltage change just after cutoff of output current. The product of the obtained reaction resistance and a meniscus length was constant regardless of a meniscus length, and useful to predict scale-up cell performance. Output characteristics dependent on meniscus position were also obtained. 16 refs., 11 figs.

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

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

    The Kibushi clay and the Gairome clay which have been taking the role as the domestic produced bonding materials for refractories are running out. This paper reports their current situation and measures from the standpoint of producers. The Kibushi clay production has been decreasing since it has peaked in 1975 at 855,000 tons down to as low as its half at 400,000 tons in 1989. The Gairome clay production has also been decreased sharply from having been produced at 30 mines to 7 mines in Gifu Prefecture. The current situation is such that not only higher cost is incurred in removing gravel beds covering the clay bed, but also no gravel disposal areas can be procured, and no profitability can be assumed because of degradation in clay quality. On the other hand, demand as raw material for sanitary earthenwares and potteries has been increasing rapidly from 2,265,000 tons to 2,779,000 tons, hence import dependence of the material is rising. Positive activities as measures against the ore depletion include an establishment of a company jointly invested by five companies in 1991, which intends to develop the industry from a mining industry to a manufacturing industry by custom-blending and reforming various kinds of clays produced in different locations, including imports, to achieve stable supply. 1 tab.

    Summarized in this report is the material already distributed concerning the program for modifying the Nakoso 200t/d pilot plant entrained bed coal gasification furnace. The program aims to verify the overall suitability for power generation use of the air-blow pressurized 2-chamber 2-stage flow entrained bed gasification furnace. Although each specific feature of gasification furnace performance is found to be satisfactory, yet a 100% operation and extended continuous operation remain to be accomplished. Slagging is a phenomenon of ash grains in high-temperature gas adhering to and growing on the furnace walls to block up the furnace to eventually disable the furnace from continuous operation. In view of past achievements and test results, it is found that slagging is closely related to the behavior of floating or molten ash and to the transition temperature range. Various slagging measures have been taken for the current gasification furnace, but they prove to be ineffective. Some drastic measures need to be implemented for improvement. Under study using model furnaces and test furnaces are the reduction of slag generation at its source (re-entrained slag), prevention of adhesion (untrapped slag), removal of slag, optimization of gyration in the furnace, modification of slag properties for enhanced discharge, optimization of the transition gas temperature range, and the modification of furnace dimensions.

    For the establishment of the basis of supercritical fluid technology, we perform elucidation of the specific feature of the supercritical fluid as a reaction media and development of some new process. In this study, we first studied the fluid structure of SCF through in-situ spectroscopy and MD simulation. As a result, significant hydrogen bonding amongst water molecules and a solvation structure around the solute were observed in the supercritical state. This fluid structure has new features different from that of high temperature steam or liquid water. We found that this is closely related to the difference of bulk properties of SCF and local one around the solute. On the basis of these fundamental findings and with the better understanding of the specific features of SCF as a reaction media, development of some new process had been conducted more efficiently and successfully. The processes being developed in this study include 1) waste biomass and plastic conversion to recover chemicals, 2) hydrogenation of heavy oil for desulphurization through partial oxidation 1 and 3) hydrothermal synthesis of metal oxide fine particles.

    In relation to softening, melting and solidification of coal during heating, the effect of heating rate and nitrogen gas pressure on viscosity change, and change with time in the yield of pyridine extract were measured to study the mechanism of viscosity change. In experiment, six kinds of coals were used, and their needle penetration and dilatation were measured using compacted disk coal pellets. The coking and slight coking coal heat-treated under the same condition as the above experiment were used for pyridine extraction. As the experimental result, the apparent viscosity during coal heating was dependent on heating rate, nitrogen pressure and coal kinds. The minimum apparent viscosity decreased with an increase in heating rate and nitrogen pressure, and approached to a constant value. Like apparent viscosity change, the yield of pyridine extract was also dependent on heating rate, and its temperature range nearly agreed with that of apparent viscosity change. It was suggested that the viscosity is dependent on not only the mass fraction of plastic intermediate but also temperature and the relation between plastic intermediate and other components. 3 refs., 5 figs., 1 tab.

    This is a summary primarily of the distributed material. As of December 14, 1995, the 200t/d pilot plant for power generation by entrained bed coal gasification records a total coal gasification operation time of 4,485 hours with an accumulated amount of power generation of 9,227MWh. A large combustor is tested, and it is found that combustion is stable under a 1/4 load with low NOx emissions. The combustor is sufficiently cooled with a small supply of air. Coal ash and coal, supplied in a constant state for an improved heat recovery efficiency in the development of hydrogen-from-coal technology, are heated to a temperature near their melting points. They are then allowed to impinge at a heat transfer plane simulating a gasifier heat recovery section, and a study is made of the mechanism of ash adhesion, molten or semi-molten, to the heat recovery section. The reduction of the heat transfer coefficient due to added grains is 30-50%, and the reduction is small when the heat transfer pipe surface velocity is high or when the carbon concentration in the grains is high. In another effort, utilization of coal-derived gas as town gas is studied. As for yields as indicated by the Curie gas pyrolyzer, the gas yield increases and liquid yield decreases when the reaction temperature is high. Using a small test unit, it is found that a rise in the hydrogen partial pressure increases the production of both gas and liquid. (NEDO)

    This paper reports the activities of the coal type committee in fiscal 1992, and summarizes the main technological achievements. In the Chinese coal liquefaction test, fiscal 1991 has performed liquefaction tests on Fushun coal by using a small continuous testing facility (0.1 t/d) at the Coal Chemistry Research Institute in Beijing. Fiscal 1992 has completed the liquefaction tests on Shengli coal. In October, a liquefaction test was carried out by using Tianzhu coal according to the NEDOL process. This paper reports the result of the liquefaction test on the Shengli coal, and the result of the analysis on the Fushun coal liquefied oil. The coal type selection and investigation having been performed to date reveals close correlation among the maceral composition of coal, coal rank and liquefied oil yield. Coals having good reactivity and suitable for liquefaction are generally suitable also for gasification. In the pretreatment of coal as a gasification material for hydrogen manufacture, a test was performed by using A heavy oil and tar sand bitumen plus A heavy oil as the granulating agents. With Montana coal, the highest de-ashing rate was achieved when the oil was added at 35% by weight. Both of the reaction rate and oil yield were improved. A handling test was carried out up to 72.5 degrees C, wherein Tatung coal presented no problems in both of the discharging and sticking tendencies. (NEDO)

    For the assurance of smooth progress of coal technology development endeavors, the New Energy and Industrial Technology Development Organization (NEDO) has installed coal technology development committees (general committee on coal technologies, coal liquefaction committee, plant materials committee, coal type survey committee, total system committee, and coal gasification committee). The coal liquefaction committee deliberates and evaluates liquefaction technology and propels forward smoothly the efforts to develop the technology. Under the coal liquefaction committee, there are four subcommittees, which are the 1st subcommittee (primary liquefaction subcommittee), 2nd subcommittee (solid/liquid separation subcommittee), 3rd subcommittee (secondary hydrogenation subcommittee), and the 4th subcommittee (brown coal liquefaction subcommittee). The 2nd and 3rd subcommittees deal with common tasks as they were studied in fiscal 1980. The 1st subcommittee incorporates into itself the old subcommittees that respectively worked on the three liquefaction processes (the direct hydrogenation process, the solvent extraction process, and the Solvolysis process), and is designed to provide a site for information exchange. A brown coal liquefaction committee is incorporated into the coal liquefaction committee as the 4th subcommittee. This report is a compilation of the agendas of the respective subcommittees of the coal liquefaction committee. (NEDO)

    A coal type research project is started under which data concerning the coal resources that Japan can make use of are to be gathered, which are necessary for determining their fitness-for-use in a coal liquefaction or gasification process, and the gathered data are to be compiled into files which are easy to use. As for the buildup of a computer-aided data bank, since the number of coal types is not yet large, only part of the data is taken into consideration this fiscal year. In the study of compiling the data into files, it is decided that the files be divided into two categories, one for grasping the status of the development project as a whole and the other for defining the positions of the individual coal specimens. Provided in the former are outlines covering the name of coal mine or project, location, entrepreneur, states of the mining area and geology, state of production, infrastructure-related matters, etc. Described in the latter are the details that enable the identification of given specimens such as the coal bed or coal brand, location and method of collection, collector, date, amount of the specimen, method of treatment, etc. (NEDO)

    This paper reports a joint meeting of the coal liquefaction committee and the coal type committee in fiscal 1993. The report is focussed on the coal type selection (the final report) for the coal used in the 150-t/d coal liquefaction pilot plant (PP) among other agenda. Initially the Australian Wandoan coal was scheduled to be selected as the reference coal for the PP operation, but the mine has not gone into operation, hence the schedule was given up. Screening was carried out to select a coal which is commercially produced and exported, and contains ash at 10% by weight or less, sulfur at 1.5% by weight or less, and chlorine at 300 ppm or less. An autoclave and a 0.01-t/d flowing type device were used to evaluate liquefaction performance, whereas the Tanito Harum coal produced in Indonesia, very similar to the Wandoan coal, was selected as a promising candidate. A PSU was used to demonstrate overall operation performance. The coal is an appropriate reference coal as seen from the aspects of liquefied oil yield, nature, operability, and site surveys in Indonesia. Among the actual record of four kinds of PSU coals in the past, the present coal has the oil yield ranked high, has the least liquefaction residues, and is advantageous economically. The oil yield per ton of coal has cleared the PP target of four barrels. The coal has less ash, is easy in solid/liquid separation in the depressurized distillation, and has no problems in operability, excepting the matter of coal supply. (NEDO)

    This paper describes a report on the material committee for coal gasification technology development in fiscal 1988. The in-plant test on new materials has performed information investigation on use characteristics and use records of new materials. A sulfurizing corrosion resistance test showed that the aluminum-chromium diffused and permeated material and the molten aluminum plated material stabilize the coated surface and have high corrosion resistance. Ceramics painted lining material was evaluated unusable in a steam diffusion test. Phenol resin was found sufficiently usable as a result of giving the stress test at 100 to 150 degrees C. In developing a let-down valve, a high-velocity water slurry injection test revealed that CVD coating of Ti (C, N) has high effect of suppressing the erosion damage. In a high-velocity powder injection test, PVD coating of TiN and CVD coating of TiC were found to show good erosion resistance. Tests and researches were performed to evaluate durability of furnace materials for manufacturing gasified hydrogen, and elucidate conditions to cause iron oxide burst. Evaluation on repairing techniques, and improvement on durability were also executed. (NEDO)

    This report is a compilation mainly of distributed material. In the development of entrained bed coal gasification power generation, gasification is tested in a 2t/d-capable facility and gasification efficiency and operation characteristics are grasped, these constituting the studies of elements to assist pilot plant operation etc. The fluid temperature point of slag is found to decrease by 200 degrees C at the maximum upon addition of flux (CaO), and this improves on slag fluidity. For the development of a demonstration gas turbine, an experimentally built combustor is tested using a real gas. A combined cycle power system is studied by simulation. In the study of pilot plant operation, measures relative to slagging are implemented, inspection and maintenance are conducted for each facility, and the combustor for a demonstration plant is subjected to oil and coal combustion tests. In the study of a pilot plant for developing technologies for hydrogen production using coal, the plant stably runs more than 1,000 hours under 100% load at in a RUN-8-3 operation. Some deposit collects in the neighborhood of the contracted area of the blow nozzle and on some part in the slip stream, but it does not affect operation. No abnormalities are detected in the cyclone or heat recovery boiler. The pilot plant is let to continue its operation, and excellent results are achieved, which are beyond the targets of carbon conversion efficiency of 98% or higher and gas cooling efficiency of 78% or higher.

    A new energy vision was established in the Murone Village area in Iwate Prefecture. The population of the village as of 1995 was 6,552 persons, which has continued with slow decrease in the last decade, revealing remarkable departure from agriculture. Energy consumption in this village per person is 11.5 two-hundred-liter drums, and carbon dioxide discharge per person is 5.6t-CO2. This is about 60% of the national average, because of no existence of thermal power plants and factories. The existing quantity of new energies is occupied by bio-mass as the largest because more than 70% of the village area is forest, followed by solar beam and heat. However, in the case of forest, since the energy is actually utilized only from the felled woods, the utilizable quantity is considerably small, whereas the availability of solar beam and heat is higher. With regard to introduction of new energies, the efforts of the introduction thereof are directed to introduction into primary schools, the village office, the special nursing home for elderly people, and the meal providing center for middle schools, in addition to proliferation and enlightenment of household solar systems, and photovoltaic power generation systems. Furthermore, discussions were given on introduction of a pellet burning power plant utilizing waste woods. (NEDO)

    This paper describes a compact bandwidth-compressed digital NTSC picture code transmission system in which circuit configurations are simplified and made inexpensive. The bandwidth of digital NTSC picture codes is compressed in accordance with subjective evaluation, and so the sampling rate is set at 8.13 MHz (2.28 times fsc) and the quantizing level at 5 bits. The frame bits for detecting the frames of picture elements me generated by alternately generating 1 and 0 when the frames are specified. The proposed system is constructed using edge- emitting LED`s (ELED`s) and single- mode (SM) fibers for transmitting digital NTSC picture codes w m to easily distribute video signals from a video camera to video monitors. The transmitter was 80 times 100mm in size, 120 g in weight, and 1000mw in power dissipation. The receiver was 55 times 120 mm in size, 100g in weight, and 800mw in power dissipation. Using the compact bandwidth-compressed digital NTSC picture code transmission system a shot of the working pice in the laser cutting machine, as an example, was satisfactorily transmitted via SM optical fibers without noses. 18 refs., 12 figs., 2 tabs.

    It was previously reported that the tritium tracer method is useful for the quantitative consideration of hydrogen behavior in coal during coal liquefaction reaction. Tetralin is excellent hydrogen donating solvent, and is considered as one of the model compounds of coal. In this study, effects of H2S and H2O on the hydrogen exchange reaction between tetralin and gaseous hydrogen labeled by tritium were investigated. It was suggested that the conversion of tetralin and the hydrogen exchange reaction between gaseous hydrogen and tetralin proceed through the radical reaction mechanism with a tetralyl radical as an intermediate product. When H2S existed in this reaction, the hydrogen exchange yield increased drastically without changing the conversion yield. This suggested that the hydrogen exchange reaction proceeds even in the reaction where radical does not give any effect. In the case of H2O addition, the conversion yield and hydrogen exchange rate decreased into a half or one-third. It was suggested that H2O inhibited the formation process of tetralyl radical. 6 refs., 4 figs.

    As a result of search for systems which have aggregate structures, the displacement reaction products of Ti with CoO or NiO are found to have aggregate structures in which the produced oxides and metals are entangled with each other. The displacement reaction of Ti with CoO or NiO is investigated at the temperature of 1273K. In the reaction of either couple, aggregate products are produced, and reacted layer is observed in the TiO2 matrix wherein Co or Ni phases are three dimensionally entangled in finely dispersed state of micron order. 2 layers of cavitated and dense TiO2 layers are found in the reacted layer. The thicknesses of the reacted layer are not constant according to locations, but thick portions are grown obeying the parabolic rate law. As a result of the study on the possibility of fabricating cermet by the reaction between powders, finely mixed characteristic structures are found to be easily obtained using systems which can produce aggregate structures. 24 refs., 9 figs.

    It is known that infrared reflection absorption spectroscopy (IRAS) on semiconductor or insulator surfaces becomes practicable by using buried metal layer (BML) substrates, in which the metal thin film is buried order semiconductor or insulator films. In this work, IRAS has been measured for Langmuir-Blodgett films deposited on the BML substrate with SiO2/Al/Si(100) structure and the observed spectrum intensity has been quantitatively compared with the calculation assuming the ideal multilayer structure for the BML substrate. The BML-IRAS using CoSi2 has been adopted to the detection of SiHn on the Si (100) substrate during synchrotron radiation (SR) stimulated Si2H6 gas source molecular beam epitaxy. It has been found that SiH2 and SiH3 on the Si (100) surface are easily decomposed by SR, but SiH can`t be decomposed. From these experiments, it has been concluded that the BML-IRAS is an useful in situ observation technique for the photo-stimulated surface reactions. 26 refs., 9 figs.

A 2-dimensional numerical model in which flow field and property conditions are simplified is used to analyze the change on the assumption that high-activity and low-activity sites are regularly distributed over the external catalyst surface. The transport equations for the reactants are numerically solved for given flow fields. It is found that the concentration distribution shape and equivalent reaction rate constant are almost the same as those in a stationary system at Pecret number of around 10 or lower, the concentration distribution gradually becomes uniform whereas equivalent rate constant increases as flow rate increases at Pecret number in a range from around 10 to 10{sup 6}, and they are almost constant at Pecret number beyond around 10{sup 6}. 3 refs., 11 figs., 1 tab.

    Molibdophosphoric acid (PMo) reacts with malachite green (MG{sup +}) to form a colored ion associate (MG{sup +}- PMo) in an acidic solution according to the formula : HMG{sup 2+}+H{sub 3}PMo{sub 12}O{sub 40}{yields}(MG{sup +})H{sub 2}PMo{sub 12}O{sub 40}+2H{sup +}. A protonated form HMG{sup 2+} is yellow (the absorption mximum at 446 nm), whereas the ion associate MG{sup +} is blue green (the absorption maximum at 650 nm). MG{sup +} is found to accelerate the formation of PMo. Water-miscible organic solvents such as methanol,ethanol and propanol also accelerate the formation of PMo as well as the formation of MG sup + - PMo. Some anionic surfactants decelerate the reaction, however, contribute to the suppression of the baseline drift in a flow injection analysis (FIA). By the use of the proposed reaction accelerator and surfactant. a highly sensitive FIA system is established for,orthophosphate up to the range of several ppb. 16 figs.. 11 refs.

    Considerations were given on the spark generating mechanism of graphite particles in molten salt polysulfide through experiments on Japanese sparklers. The firework composition mixed consisted of two kinds: KNO{sub 3}, S, amorphous carbons, charcoal and lamp black, and K{sub 2}CO{sub 3}, S, charcoal and lamp black. The main constituent in fire balls is molten salt polysulfide. The O{sub 2} generated from combustion oxidizes C and S, whereas the generated K{sub 2}CO{sub 3} reacts with S to produce K{sub 2}Sn. In the KNO{sub 3} system, the calorific power reaches the maximum with lamp black contained at 10-15%. This is thought because the K{sup +} expands the space between the graphite crystal layers making the oxidation to take place more easily into their inner sides. On the one hand, the calorific power reduced with the lamp black at more than 16% would be because the lamp black clogging the crystalline spaces restricting the oxidation. It is thought that condensation and decomposition of micro graphite crystals occur simultaneously in the fire balls. It is also believed that the micro graphite crystals jumped out as a result of gas pressure from inside the crystals generated with the progress of oxidation break off at once because of the resistance of air together with the effect of the K{sup +} in the salt polysulfide (mutual separation of each layer). 9 refs., 6 figs., 1 tab.

    Mature nonstructural protein-15 (nsp15) from the severe acute respiratory syndrome coronavirus (SARS-CoV) contains a novel uridylate-specific Mn{sup 2+}-dependent endoribonuclease (NendoU). Structure studies of the full-length form of the obligate hexameric enzyme from two CoVs, SARS-CoV and murine hepatitis virus, and its monomeric homologue, XendoU from Xenopus laevis, combined with mutagenesis studies have implicated several residues in enzymatic activity and the N-terminal domain as the major determinant of hexamerization. However, the tight link between hexamerization and enzyme activity in NendoUs has remained an enigma. Here, we report the structure of a trimmed, monomeric form of SARS-CoV nsp15 (residues 28 to 335) determined to a resolution of 2.9 Angstroms. The catalytic loop (residues 234 to 249) with its two reactive histidines (His 234 and His 249) is dramatically flipped by {approx}120 degrees into the active site cleft. Furthermore, the catalytic nucleophile Lys 289 points in a diametrically opposite direction, a consequence of an outward displacement of the supporting loop (residues 276 to 295). In the full-length hexameric forms, these two loops are packed against each other and are stabilized by intimate intersubunit interactions. Our results support the hypothesis that absence of an adjacent monomer due to deletion of the hexamerization domain is the most likely cause for disruption of the active site, offering a structural basis for why only the hexameric form of this enzyme is active.

    The purpose of this project is to clarify the possibility of new hydrogen energy as a future energy source. The new hydrogen energy is obtained from the excess heat generation phenomenon through the electrolysis of heavy water using palladium metal as an electrode. The excess heat measurements were conducted through the excess heat confirmation tests using a fuel cell-type electrolytic cell up to November 1997. As a result, it was found that the excess heat measured by the calibration method can not be measured by the flow calorimetric method. In order to investigate the possibility of systematic errors of the both methods, the sensitivity, accuracy and responsibility, and the conditions of the excess heat generation, research activities based on new facts from scientific information and fundamental research supporting projects have been mainly performed. Among these, were performed the excess heat measurement tests by the cataphoresis method, absorption tests by the high-pressure and high-temperature charging method, gas plasma loading, in-situ X-ray detection, and reactant detection tests using Au/Pd/PdO heterogeneous structural body. 5 refs., 59 figs., 9 tabs.

    Such foaming materials as styro-foam, urethane and polyethylene greatly increase load on the environment when discarded, and are a problem as harmful rubbish. On the other hand, magazine waste papers have limitation as regenerated paper because their pulp fibers are cut off and deteriorated during use and regeneration. They are left unused without a prospect of re-use even if recovered. Under such a background, the present research and development is intended to develop magazine waste papers as a reusable cushioning material, commercialize the cushioning material as a low environment load type material, and promote reutilization of magazine waste papers. Specifically, development is performed on a manufacturing technology and a manufacturing equipment for a cushioning material having excellent biodegradation performance manufactured by mixing magazine waste papers with gelatin as a binder, and further by foaming and forming. The research and development items include: (1) development of a manufacturing technology for a foaming eco-material using magazine waste papers, (2) development of manufacturing equipment for the foaming eco-material, and (3) the market research thereon. This paper reports the achievements in the research and development of each item in fiscal 1998. (NEDO)

    The effort aims to prepare the base of a next-generation ultrahigh density HDD (hard disk drive) industry in the Tohoku district. The contact head was modeled as a cantilever beam and a head disk linkage impact model for analysis was built for the elucidation of the effects of various factors. A microactuator using a PZT (piezoelectric transducer) thin film was evaluated concerning the constitution of its elements, and durability. Materials design guidelines were indicated concerning the moderation and suppression of thermomagnetism in the ultrahigh density magnetic recording medium. A grain diameter of less than 10nm was found necessary for a decrease in the interaction between magnetic crystal grains for the achievement of a reduction in noise, and a material was produced that met the condition. An appropriate abrasive was chosen for superfine surface processing. Attention was paid to the chemical loss of lubricating oil to cause lethal destruction of HDI (hard disk interface) and , after evaluating hard film and frictional conditions, it was found that a hard layer and soft layer were required to complete an effective lubricant film. A ferroelectric body and a shape memory alloy were combined into a composite lamination and crystal orientation therein was controlled, and the lamination showed its feasibility as a thin film actuator.

    The purpose of this project is to clarify the possibility of new hydrogen energy as a future energy source. The new hydrogen energy is obtained from the excess heat generation phenomenon through the electrolysis of heavy water using palladium metal as an electrode. The excess heat regeneration tests have been successively conducted using two kinds of electrolytic cells. As a result, the excess heat generation measured by one electrolytic cell in FY 1996 has been confirmed in about 35% of repeatability under the same condition. On the other hand, the excess heat over the measuring accuracy was not measured using two kinds of absolute heating value measuring systems. The electrolytic cell, by which the excess heat was measured, was used for confirming the absolute heating value as keeping its condition. When tests were conducted using the developed system, it was found that the absolute heating value can not be detected. Then, verification tests are currently conducted for determining the cause. Moreover, in order to clarify the basic characteristics of materials required for the regeneration of the excess heat generation phenomenon, observation and analysis of the materials were performed before and after the excess heat measurement. Thus, the cause of difference was revealed. 3 refs., 98 figs., 24 tabs.

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

    Development of basic technology was conducted on a superstructure lattice element. With an objective of developing a molecular beam epitaxy (MBE) method, which is the basic technology for preparing the superstructure lattice element, the development of silicon clean surface preparing technology was performed, as were the development of molecular beam source, the development of two-dimensional analytical program for designing the element, etc. For the clean surface, comparison was made on various methods, developing a method capable of making a clean surface usable for the MBE fully by a low temperature process that had been non-existent. This was a low temperature thermal etching method which jointly uses a chemical process and a low warmth process. In the molecular beam source, it was found that a large size was necessary for the purpose of improving the purity of the molecular beam and also the characteristics of an epitaxial film, so that a large molecular beam source was developed. A conventional two-dimensional analytical program was improved and developed for the purpose of designing the superstructure lattice element and clarifying the characteristics. By applying the result to the analysis of the motion of the element with impurities doped in the manner of a superstructure lattice, the effectiveness was confirmed of this analytical method. (NEDO)

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

    This paper describes technology assessment on a hydrogen fueled aircraft system. Indispensable as technological assignments are structuring different safety systems including prevention of leakage and ignition, not to speak of developing an airframe structure that considers cryogenic and brittle nature of liquefied hydrogen. Operation related industries would be subjected to increased burdens, such as purchase and servicing of new implements and materials, but the liquefied hydrogen industry will have a chance of growing largely with wide repercussions. In the environmental aspect, the aircraft will have less CO and SOx emission in exhaust gas and lower noise than the conventional jet aircraft. Technological problems to be solved in the development include the safety of fuel tanks, safety assurance measures, and liquefied hydrogen of the required amount to be supplied easily and at low cost. To meet these requirements, noticeable progress is demanded in hydrogen manufacturing technologies. What is also required is explosion-proof safety that does not have to require crews to take special considerations in take-off and landing, not to speak of during flight. This also applies to fuel feeding and servicing on the ground. Considerations must be given that rise in operation cost should not be excessive. (NEDO)

    This research program consists of (1) the solid catalyst-aided reforming of various petroleum based oils and heavy coal oils into Solvolysis solvents and the secondary hydrogenolysis, (2) a search for pre-treatment for improvement on the sub-bituminous coal liquefaction yield, and (3) a search for measures for improvement on the brown coal liquefaction yield. Studied in this fiscal year are (1) the high-temperature short-contact time liquefaction of brown coal, (2) the role of catalyst support for selective upgrading of SRC (solvent refined coal), and (3) reforming of thermal melting feature of low rank coal by preliminary deashing at room temperature. In relation with Item (1), it is found that the dehydrogenation or reaction to carbonization of molecules involved in hydrogen donation is structure-sensitive but that thermolysis of coal is accelerated under high-temperature conditions to allow transfer hydrogen to contribute uniformly. It is deemed also that matching is excellent between hydrogen transfer and thermolysis, that the solvent dissolution level is elevated, and that the reaction short in duration inhibits consecutive polymerization reaction. These are supposed to be effective in improving on the liquefaction yield and in rendering heavy constituents lighter. In relation with Item (2), it is found that the experimentally manufactured catalysts are effective in reducing the weight of heavy constituents. In relation with Item (3), a carbonization reforming method is experimentally implemented in which the ash that affects carbonization is further removed by a pre-treatment at room temperature.

    The purpose of this project is to develop new 2-dimensional ultrafast MRI (Magnetic Resonance Imaging) methods for the Image Guided Cancer Therapy (IGT) and the non-invasive clinical diagnosis. We have developed two MRI methods. They can reconstruct a two dimensional image by only a RF excitation and slow changing of gradient fields. This paper describes theoretically how to apply the RF wave and the gradient in x, y and z direction, respectively. Echo signals are acquired under multi-frequency resonance. The frequency bandwidth of the RF wave adjusts the field of view (FOV) of the imaging plane. Biological effects of the applied RF wave was evaluated by the brain microdialysis. In animal experiments, these was not significant change of neurotransmitters subject to the RF wave. From these theoretical and experimental results, these MRI methods are applicable to IGT and the clinical diagnosis for the cancer and other diseases. (NEDO)

    All optical wavelength conversion around 1550nm is of great importance for the wavelength division multiplexing optical communication system. A dielectric domain superlattice, which has a periodically domain inverted structure, has a wide potential for the various nonlinear interactions such as second harmonic generation (SHG) and difference frequency generation (DFG). The purpose of our research is to establish the theoretical bases and fabrication processes of the guided-wave wavelength converter based on the DFG by domain-inverted LiTaO{sub 3}. We have investigated basic characteristics of guided-wave DFG devices and developed the domain-inversion process by an electric field poling utilizing a liquid electrolyte consisting of LiCI in deionized water as a electrode for applying the electric field to LiTaO{sub 3} substrate. By controlling the injection current for the domain inversion precisely, we fabricated successfully uniform domain-inverted structures. 0.5mm-thick domain-inverted LiTaO{sub 3} of 7.8, 17.2 and 21.3 {mu}m periods and 0.5 duty ratio were obtained by optimizing electrode structure and the domain-inversion process. Waveguide structures can increase the conversion efficiency of DFG by several orders of magnitude over bulk interactions. We have also developed waveguide fabrication process for the domain-inverted LiTaO{sub 3} substrate. Low loss proton-exchanged waveguides were formed by annealed proton exchange technique without a degradation of the domain inversion structure. Domain-controlled nonlinear optics by designing the ferroelectric domain structure of LiTaO{sub 3} and LiNbO{sub 3} make it possible to extend all the spectral range from ultra-violet to far-infrared and THz wave region.

    Surveys and studies were conducted to establish a practical SNG (substitute natural gas) production process. In the study of coal hydrogasification, a mathematical simulation was implemented to estimate the distribution of products with the pyrolytic reaction and the hydrogenolytic reaction controlled independently in the ARCH-2 (advanced rapid coal hydrogasification-2) process, the said two reactions representing the key concepts of the ARCH-2 process. It was then disclosed that a two-stage reaction control would increase the liquid yield. Also, a tentative calculation was made of gas cooling efficiency and cost performance in a process capable of achieving the target liquid acquisition rate. It was then found that BTX (benzene, toluene, xylene) production up to approximately 15% in terms of carbon was feasible and that the SNG price would be 29.03 yen/Nm{sup 3} with benzene priced at 90 yen/kg, these promising a better result than in the ARCH-1 process. The gas cooling efficiency of the ARCH-2 process was but 72.0% or less, however, which demanded improvement. Studies were made, based on the results of studies in progress since fiscal 1990, about what the hydrogasification process for Japan to develop should be. (NEDO)

    Recently, environmental pollution by a large amount of undecomposable waste has became a serious problem. Therefore, biodegradable polymers, which can be degraded by environmental species such as bacteria and enzymes, have been studied extensively. Most of the biodegradable polymers prepared so far were polyester derivatives such as poly(hydroxybutyrate/valerate), poly(lactide) and poly(glycolide). The degradation mechanism is the hydrolysis of the ester groups in the main chain of the polymer which is facilitated by enzyme degradation. Most of the mass-produced polymers, however, are vinyl-polymerized plastics such as poly(ethylene), poly(propylene) and poly(styrene). There is no technology on the degradation of such vinyl polymers except in the lithography field, in which it is known that some vinyl polymers can be used for posi-type resists by decomposition with UV or electron-beam (EB). For creation of degradable polymers, the following three factors must be considered Purpose of the project seriously; 1) What degrades the polymers? 2) Row long does the polymer maintain the initial properties? (Time course of the mechanical strength, etc.) and 3) Bioactivity of the liberated oligomers. The aim of our work is the creation of new polymers which can be easily controlled by the above three factors. If we can degrade the polymers from the end of the polymer chain, i) we can control several properties of the polymers in the degradation such as degradation source (pH, light,, UV, EB, etc.) and rate of the degradation by changing the structure of the end group; 2) production of oligomers, which may induce a significant problem in terms of bioactivity, can be suppressed because of the depolymerization from the end of the polymers (only the monomer will be liberated). In this project, we investigated to synthesize the end functionalizations of poly({alpha}-methylstyrene) derivatives and their degradation characteristics using temperature, acid and alkaline conditions. To induce degradabilities in polymers in response to environmental conditions, the end-modification reactions of poly({alpha}-methylstyrene) (PMS) derivatives were carried out. When diphenylphosphine chloride was used as a modifier for the living end of para-substituted PMS, the coupling efficiency was ca. 50%. 2-Phenylallyl halide derivatives such as 2-phenylallyl bromide, 2-(4-tolyl)allyl bromide, and {alpha}-trifluoromethylstyrene were found to be suitable end-modification agents. For example, {omega}-2-phenylallyl PMS was prepared with almost quantitative functionality by the reaction of the living PMS with 2-phenylallyl bromide. In a similar way, {omega}-3, 3-difluoro-2-phenylallyl and {omega}-2-(4-tolyl)allyl PMS derivatives were synthesized. Based on thermogravimetric analysis, onset of the degradation temperature of the end-modified PMS derivatives decreased in the following order: {omega}-hydrogen- > {omega}-3,3-difluoro-2-phenylallyl- > {omega}-2-phenylallyl- > {omega}-2-(4-tolyl)allyl-PMS. Actually, the onset temperature of {omega}-2-(4-tolyl)allyl-PMS derivatives was 50 degree C lower than that of {omega}-H-PMS derivatives. These results indicate that the active species is produced effectively at the end unsaturated bond, which initiates the depolymerization of the polymer at rather low temperatures. Ionic degradation of these polymers was also investigated using butyllithium as an anionic initiator and methanesulfonic acid as a cationic initiator Tendencies similar to the thermal degradation were observed. Therefore, it is concluded that a 2-phenylallyl substituent at the end of the PMS chain induces effective degradation through several mechanisms such as radical, anionic and cationic depolymerization reactions.

    This report summarizes the fiscal 1999 research result on simulation analysis on petroleum substituting energy. The simulation model for analyzing social and energy supply and demand structures comprehensively was established by improving the China and Korea models developed in fiscal 1998 through a use of input-output tables. In simulation of the China model, the reference case showed that a primary energy demand in 2030 reaches 3.3 times as much as that in 1997 (2.9 times in CO{sub 2}), resulting in serious energy and environment problems. Reduction of primary energy and CO{sub 2} is possible by promotion of energy saving and introduction of a carbon tax. In simulation of the Korea model, the reference case showed that CO{sub 2} emission in 2030 reaches 2.2 times as much as that in 1997, showing an annual increase rate of 2.4%. The annual increase rate can be reduced by introducing a carbon tax. The simulation model for automobile energy was also established for major countries in Asia. Automobile energy consumption increases with diffusion of automobiles until 2030 gradually. In particular, the consumption in China reaches that in Japan in 2010. (NEDO)

    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)

In the study of hydrogenation refining of the naphtha fraction under the project for 'the upgrading of coal oil and the development of oil blending technology,' a hydrogenation experiment is conducted for deheterocyclicity for in the naphtha fraction (90-180 degrees C). The neutralization process is found to greatly accelerate denitrification, multiplying the rate constant 2-5 times at 300 degrees C. In the research and development of application technologies, the ASTM-D4625-86 method is applied to the storage test of crude oils such as naphtha from liquefied Yallourn coal, kerosene, and light oil, and the results are compared with those from natural storage. It is then found that this acceleration test is applicable even to oils from coal liquefaction. In the research and development of novel catalysts, it is found, relative to the 1st-stage hydrogenation catalyst, that an increase in the amount of supported tungsten enhances the activity and life of the catalyst and, relative to the 2nd-stage hydrocracking catalyst, that YD zeolite is effective in prolonging the life of the catalyst.

The survey was carried out aiming at contributing to the international development of Japan's energy policy in future by quantitatively analyzing/evaluating influences of various energy policies/economic policies on the economy and energy supply/demand, through various kinds of simulation models. In FY 1998, information collection for modeling was made in China and Korea out of the Asian/Pacific region. At the same time, pilot models were constructed, and simulation was made for the standard case. Moreover, an analysis was conducted of the relation between economic growth and motorization in each country of the world as the basic data preparation on energy consumption in the transportation sector.

    Research and development was carried out concerning the automatic parallelized compiler technology which improves on the practical performance, cost/performance ratio, and ease of operation of the multiprocessor system now used for constructing supercomputers and expected to provide a fundamental architecture for microprocessors for the 21st century. Efforts were made to develop an automatic multigrain parallelization technology for extracting multigrain as parallelized from a program and for making full use of the same and a parallelizing tuning technology for accelerating parallelization by feeding back to the compiler the dynamic information and user knowledge to be acquired during execution. Moreover, a benchmark program was selected and studies were made to set execution rules and evaluation indexes for the establishment of technologies for subjectively evaluating the performance of parallelizing compilers for the existing commercial parallel processing computers, which was achieved through the implementation and evaluation of the 'Advanced parallelizing compiler technology research and development project.'

    Surveys and studies were conducted to establish a practical SNG (substitute natural gas) production process. Dealt with in the survey of basic studies on hydrogasification were the effect of gasification conditions, mechanism of tar decomposition, model-using estimation and assessment of reaction heat, and so forth. In an effort to develop a reactor, the current status was studied and future tasks were extracted concerning the one-through type and the internal circulation type entrained bed hydrogasification furnaces. In the study of practical application of the coal hydrogasification process, it was found that gas cooling efficiency would be increased from last fiscal year's 75.2% to approximately 78% by optimizing the process configuration. An ARCH (advanced rapid coal hydrogasification) process to have a novel reactor was proposed, and, for its commercialization, guidelines for dimensionally enlarging the process were worked out and tasks to discharge at each of the development stages were extracted. Relative to pilot tests, an efficient development program was deliberated, in particular, which comprised ARCH-1 and ARCH-2. (NEDO)

    To cope with the global warming caused by CO2, an investigation was conducted into biological fixation. It is necessary to make a many-sided and comprehensive study on the mechanism of CO2 fixation, the scale (area and carbon holding density), the rate and the environmental impact of the introduction of the technology and the technical problems, and to make a quantitative evaluation of each of the methods in order to make them practical proposals. The global ecosystem is classified into the land biota and ocean biota, and each typical ecosystem was surveyed in terms of the surface area, the carbon holding amount (presently existing amount), the net primary production amount, the required nutrient salt amount, the transpiration rate, etc. Next, a discussion was made on the increasing effect of the carbon fixation amount by changing the present ecosystem from the aspect of scale and rate. At the same time, a study was carried out of energy efficiency, economical efficiency and problems. Last, elementary technology was taken up which seems to be important for implementing measures for the biological carbon fixation. As to the ocean, it is necessary to obtain information, which is not sufficient to utilize marine biota for CO2 fixation, especially on the mechanism of depth-direction transfer of organism and its quantitative grasp. As to the land, one of the measures is conversion of the ecosystem where the amount of carbon fixed is small to the ecosystem where the amount is large. 249 refs., 58 figs., 51 tabs.

    The depression of the reaction between SiC and Ni, by adding TiO2 powder in spraying powder which has caused uniform dispersion in spray coating and reduction of TiO2 by the reaction during spraying, was studied. The mass ratio of the mixed components has been, SiC:Ni:TiO2=3:2:1. The spray coating was examined by electron prove microanalysis as well as X-ray diffractometry, centering mainly to the SiC-metal interface reaction. The formation of Ni-Si compounds have been depressed by the addition of TiO2 to spraying powder and by using plasma gas containing H2. Reason for this has been that the TiC formed in the SiC-Ni interface has depressed the reaction at the SiC-Ni interface. Further, TiO2 is reduced during spraying, and TiC is thought to be formed by the reaction between Ti and SiC or reaction between TiO2 and SiC. 8 refs., 6 figs., 1 tab.

    Full Text Available La diffusione del pentecostalismo e la crescita degli aderenti ha assunto negli ultimi decenni dimensioni considerevoli che ne hanno fatto il movimento cristiano a più altro tasso di crescita a livello mondiale. Sebbene conosca una sua diffusione anche nelle aree rurali, è in quelle urbani che conosce uno sviluppo maggiore. Tra i fattori che ne hanno favorito la diffusione vi è certamente la flessibilità dell'idioma pentecostale che permette di adattarsi ai vari contesti locali. Diversi studiosi hanno evidenziato come versioni oggi più in crescita del pentecostalismo presentino nella dottrina, nelle predicazioni e nelle pratiche elementi coerenti con la prospettiva neoliberista oggi egemonica in larga parte del pianeta. Partendo dagli articoli presenti in questa sezione, il contributo intende riflettere su queste questioni, concentrandosi principalmente sul fenomeno per come si presenta nelle aree urbane.

    A study is conducted of a plan to repower the Ashuganji thermal power station, the People's Republic of Bangladesh, with the plan to be connected to the clean development mechanism (CDM). For conversion of the existing No. 3, No. 4, and No. 5 generators (each outputting 150MW) into full fired heat recovery combined cycle generators, 31MW gas turbines are added, one to each of the three. The construction cost is calculated to be 14,000-million yen. Fuel (natural gas) will be saved by 28kt/year/generator, the three saving 2.1-million tons in total in 25 years. There will be a CO2 reduction of 77kt/year/generator, the total reduction to be 5.8-million tons in 25 years for the three generators. Then payback is assessed. In the main case (with the repowering-created increase in output to be used to cover the current power supply shortage), where the internal rate of return of 8.09% is much lower than the discount rate of 15.5% during the 10-year period for payback in case of financing by private funds, the discounted present worth is predicted to be negative and then the project is not feasible. Since there will be no problems about the repayment of borrowed money, however, it is hoped that low-interest special yen credit will be granted for the elimination of chronic power shortage. When it comes to international emission trading (550 yen/ton of CO2), payback is again found to be impossible. (NEDO)

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

    A survey was conducted of the current status of energy supply/demand, future problems, goals of the energy policy, basic plan, and so forth, for the formulation of a new energy vision for the city. Concerning energy supply/demand, studies were made of each sector, area, and energy source. In the study of energy demand, it was discovered that, although the industrial sector in the coastal region remained important, the residential/commercial sector was gathering weight and that the city was serving as an energy supply base for the neighboring areas. In the study of new energy, it was found that the available amount of solar energy resources was enormous, that the Tama river fresh water and the Keihin canal seawater constituted a promising source of temperature difference energy, and that sewage energy, transformation station exhaust heat, LNG (liquefied natural gas) cold heat, and so forth, were also available as energy sources.

    In search of measures for popularizing thermal storage technology in Japan, investigations were conducted into the conditions of electric power and the state of DSM (demand side management) in Italy, Spain, Portugal, and Greece whose climate is similar to Japan's. The results of the effort were edited and classified into six items, which are (1) power conditions, (2) DSM status, (3) popularity of thermal storage, (4) merits of thermal storage, (5) measures for thermal storage popularization, and (6) propositions to Japan. In all the countries, the power demand peak has shifted to the summer season or the difference in demand for power between summer and winter has decreased and, except in the case of Greece, the load factor has increased, these due to the increase in demand for power for cooling equipment. In Greece, the load factor has decreased since the peak shifted to summer. In every country, the rate schedule based on season of the year and time of the day is treated as a basic incentive for DSM. Except in Greece, there is no summer demand suppression type DSM menu and efforts are being exerted rather to have loads built in off-peak time zones. As for thermal storage systems in use, they are mostly of the ice-aided type. Those in the residential/commercial sector are on the increase, and it is estimated that 50% of ice thermal storage systems will be found in this sector in 2000. (NEDO)

    The project, with attention paid to both spin and charge of electrons, aims to draw the best of the said two attributes of electrons by use of the state of the art in manufacturing technology for the creation of novel electronic devices. 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.

    This paper summarizes the research result in fiscal 1997 from the basic research results on the commercialization of innovative energy technologies. The target of a photovoltaic power generation market includes isolated power sources (several kWp) for distant places or developing countries, and those (several tens kWp) for personal residences or public facilities. Although the former is mainly promoted in the West, while the latter over the world, their profitability is unsolved. Power plants over several hundreds kWp are in demonstration test. Solar heat power generation of several tens to hundreds MWp is most profitable, however, small-scale one is poor in feasibility. Australia takes an interest in distributed photovoltaic power generation directly connected with actual lives of residents, and has a dominant opinion that desert is useless as large-scale site. This country lays emphasis on protection and maintenance rather than positive use of desert based on a basic cognition that desert is easily changed and broken. The Australian government announced power company`s obligation to use renewable energy by 2%, and a strong organization is scheduled to be newly established. 59 figs., 57 tabs.

    For every solar energy utilization field, its background, feasibility, impact in practical use, and R and D policy in Japan were studied. Heating and hot water supply by solar energy are already practical because of less technical problems and reasonable profitability, and cooling is also practical as far as a technical viewpoint. At present, the technical level of solar heat power generation is in the stage of basic technology, however, in the future, development of economically reasonable systems will be demanded as well as establishment of its technology. The most difficult problem for realizing practical solar cell power generation systems is cost reduction. It is also another problem that a big demand of Si for solar cells further exceeds the current yield of Si in a semiconductor industry. A small-scale hybrid solar cell power generation system applicable to the roof of general residences is already feasible. Although a solar furnace is still poor in application to industrial fields, it is expected as the leading part for a future solar heat chemical industry. (NEDO)
