    Discrepancies between calculated static reactivities and measured reactivities evaluated with reactivity meters led to investigating SCRAM with the KIKO3D dynamic code, The time and space dependent neutron flux in the reactor core during the rod drop measurement was calculated by the KIKO3D nodal diffusion code. For calculating the ionisation chamber signals the Green function technique was applied. The Green functions of ionisation chambers were evaluated via solving the neutron transport equation in the reflector regions with the MCNP Monte Carlo code. The detector signals during asymmetric SCRAM measurements were calculated and compared with measured data using the inverse point kinetics transformation. The sufficient agreement validates the KIKO3D code to determine the reactivities after SCRAM. (Authors)

    This paper reports the result on R and D of the femtosecond technology in fiscal 1997. Ultrahigh-speed electronic technology is indispensable for industrial basic technologies supporting the advanced information society in the 21st century. Control technology of photonic and electronic states in a femtosecond region is essential. In R and D of metrological technology using ultra-short light-pulses, study was made on generating and controlling technology for ultra- short light/electron beam pulses. Ti-sapphire mode-locked laser was prepared, and it was found that time-fluctuation of mode-locked laser pulses is measurable up to 100 femtosecond level. As measures against an instability of gain-switching semiconductor laser, light injection from the outside was effective. The stable directivity of laser beam was obtained by regenerative amplifier, while less temperature variation of an optical switch was necessary to stabilize energy. To generate femtosecond high-intensity X-ray pulse by collision of laser and electron beams, it was confirmed that sub- picosecond synchronization is possible by RF and picosecond laser synchronization circuit. 48 refs., 89 figs., 11 tabs.

    In fiscal 1997, study was made on formation of peptides with a biogenic function and molecular recognition function, and peptide materials. The existing automatic design technique of peptides including non-natural amino acids was applied to design of complementary peptides of proteins with known structures to optimize a development technique of ligand. Practical function of peptides as advanced receptor ligand was verified by applying the existing conformation control technique to stable holding of peptide active conformation. Creation of bio-materials, and development of preparation technology of bio-substrates and materializing technology of functional molecular materials were carried out. To construct an electron transfer system by self- organized body of peptides formed on a substrate, a peptide molecular device was prepared and verified using linkers. To use peptides as photoelectron functional molecule, metallized peptide with main helix structure was prepared. The possibility of molecular materials with a fixation function of CO2 was examined.

    The paper describes the numerical methods applied in KIKO3D three-dimensional reactor dynamics code and present a new, more effective method (Bi-CGSTAB) for accelerating the large sparse matrix equation solution. The convergence characteristics were investigated in a given macro time step of a Control Rod Ejection transient. The results obtained by the old GMRES and new Bi-CGSTAB methods are compared. It is concluded that the real relative errors of the solutions obtained by GMRES or Bi - CGSTAB algorithms are in fact closer together than the estimated relative errors. The KIKO3D-Bi-CGSTAB method converges safely and it is 7-12 % faster than the old KIKO3D-GMRES solution (Authors)

    The goal of this paper is to present a more effective method Bi-CGSTAB for accelerating the large sparse matrix equation solution in the KIKO3D code. This equation system is obtained by using the factorization of the improved quasi static (IQS) method for the time dependent nodal kinetic equations. In the old methodology standard large sparse matrix techniques were considered, where Gauss-Seidel preconditioning and a GMRES-type solver were applied. The validation of KIKO3D using Bi-CGSTAB has been performed by solving of a VVER-1000 kinetic benchmark problem. Additionally, the convergence characteristics were investigated in given macro time steps of Control Rod Ejection transients. The results have been obtained by the old GMRES and new Bi-CGSTAB methods are compared. (author)

    Bucklings (n = 275) from a complete diallel of Boer, Kiko, and Spanish meat goats were slaughtered at 7 mo of age (4 mo postweaning) to evaluate genetic effects on carcass yield. Breed of sire did not affect (P > 0.05) live, carcass, and primal weights. Conversely, breed of dam was a consistently significant source of variation for carcass weight traits. Kiko dams produced kids with heavier (P 0.05) from Boer or Kiko. Subjective conformation scores for muscularity were affected (P 0.05) by breeds of sire or dam. Direct effects of Boer were negative for carcass weight, dressing percent, and shoulder weight and positive for proportional leg weight. Direct effects of Kiko were positive for carcass weight and shoulder weight and negative for proportional leg weight. Direct effects of Spanish did not differ (P > 0.10) from 0 for any trait tested. Heterosis levels were similar among breed pairings. Heterosis was substantial (P ≤ 0.05) for live, carcass, and primal weights (5 to 9%) but not for dressing percent, proportional boneless meat yield, or primal weight proportions (genetic variation was observed among goat breeds for carcass yield traits. Dam breed was more influential than sire breed. Boer germplasm was not superior to Kiko or Spanish germplasm for carcass yield when semi-intensively managed on humid, subtropical pasture. Results emphasize the importance of comparative breed evaluations to provide industry with reliable information on carcass yield among goat genotypes.

    An overview is given on the investigations of the Main Steam Line Break transient in a VVER- 440 NPP by using the KIKO3D/ATHLET 1.2.A coupled code system. Special attention was paid for the influence of modeling the outcore detector signals and the malfunctioning of the emergency control system (scram with stuck rod). The conservatism of the calculations was assured even in the case of application of the 3D best estimate KIKO3D code. The consequence of MSLB accident is investigated at the end of cycle (EOC), at full power (FP) and shut down initial conditions. Even if very strong conservative assumptions were applied, dangerous hot spots were not found in the supposed scenarios.(author)

    Traffic jams are investigated numerically and analystically in the optimal velocity model on a single-line highway. The condition is found whether or not traffic jams occur when a car stops instantly. It is shown that traffic soliton appears at the threshold of occurrence of traffic jams. The Korteweg-de Vries (KdV) equation is derived from the optimal velocity model by the use of the nonlinear analysis. It is found that the traffic soliton appears only near the neutral stability point. The soliton obtained from the nonlinear analysis is consistent with that of the numerical simulation. (author)

    Boer, Kiko, and Spanish meat goats were semi-intensively managed in a complete 3-breed diallel mating scheme to evaluate genetic effects on preweaning kid performance. Over a 6-yr period, 1,547 kids were born in March and May with 1,173 kids raised by their dams to weaning at 3 mo of age. March-born kids were lighter (P 0.10). Maternal Boer effects were negative (P 0.5) for preweaning ADG or weaning weight. Heterosis for birth weight was exhibited (P genetic variation was observed between meat goat breeds for kid performance to weaning. Maternal breed effects were more influential than direct breed effects. Boer goats were not superior to Kiko or Spanish for preweaning kid performance when semi-intensively managed on humid, subtropical pasture. Kiko should be a preferred breed and to a lesser extent Spanish for enhancing birth to weaning kid performance. Findings of this study emphasize the importance of proper doe breed selection in achieving desired kid performance to weaning in meat goats.

    Full Text Available Abstract Background Longevity is the amount of time breeding females stay active in a herd by avoiding death or culling because of illness or reproductive failure. This is a trait of economic relevance in commercial small ruminant breeding herds as it affects lifetime reproductive output. The purpose of this study was to determine if breed of meat goat influences breeding doe survival rates and cumulative reproductive performance under semi-intensive management. Results Boer (n = 132, Kiko (n = 92 and Spanish (n = 79 does were evaluated for longevity trends and cumulative kid production. The herd was managed on humid subtropical pasture. Does had the chance to complete 2 to 6 production years. Survival curves were analyzed for 2 culling methods. The actual culling practice removed does after two failures to wean a kid. An alternative culling protocol removed doe records after the first failure to wean a kid. Kid production traits analyzed across herd life were the total number of kids weaned and cumulative kid weight weaned to the 2-, 3-, and 5-year stayability endpoints. Most (82% doe exits were illness-related under the actual culling method. Reproductive failure represented 51% of doe exits under the alternative culling protocol. Boer does had greater survival declines (P P P  Conclusion Boer does had low stayability and cumulative kid production rates compared with Kiko and Spanish does. Poor health was the primary driver of does exiting the herd. Kiko and Spanish does did not differ for longevity and lifetime performance indicators.

  18. Knock-in/Knock-out (KIKO) vectors for rapid integration of large DNA sequences, including whole metabolic pathways, onto the Escherichia coli chromosome at well-characterised loci.

    Metabolic engineering projects often require integration of multiple genes in order to control the desired phenotype. However, this often requires iterative rounds of engineering because many current insertion approaches are limited by the size of the DNA that can be transferred onto the chromosome. Consequently, construction of highly engineered strains is very time-consuming. A lack of well-characterised insertion loci is also problematic. A series of knock-in/knock-out (KIKO) vectors was constructed for integration of large DNA sequences onto the E. coli chromosome at well-defined loci. The KIKO plasmids target three nonessential genes/operons as insertion sites: arsB (an arsenite transporter); lacZ (β-galactosidase); and rbsA-rbsR (a ribose metabolism operon). Two homologous 'arms' target each insertion locus; insertion is mediated by λ Red recombinase through these arms. Between the arms is a multiple cloning site for the introduction of exogenous sequences and an antibiotic resistance marker (either chloramphenicol or kanamycin) for selection of positive recombinants. The resistance marker can subsequently be removed by flippase-mediated recombination. The insertion cassette is flanked by hairpin loops to isolate it from the effects of external transcription at the integration locus. To characterize each target locus, a xylanase reporter gene (xynA) was integrated onto the chromosomes of E. coli strains W and K-12 using the KIKO vectors. Expression levels varied between loci, with the arsB locus consistently showing the highest level of expression. To demonstrate the simultaneous use of all three loci in one strain, xynA, green fluorescent protein (gfp) and a sucrose catabolic operon (cscAKB) were introduced into lacZ, arsB and rbsAR respectively, and shown to be functional. The KIKO plasmids are a useful tool for efficient integration of large DNA fragments (including multiple genes and pathways) into E. coli. Chromosomal insertion provides stable

    For the purpose of promoting the utilization of energy from waste, studies were conducted on the dioxin emission mechanism and non-Br base fire retardant materials which emit no Br base dioxin, and the FY 1999 results were summarized. In the study, using a small-fluidized bed experimental incinerator, survey was made of effects of organic/inorganic chlorine included in solid general waste on the formation/discharge of dioxins. As a result of the experiment, it was found out that organic chlorine compounds discharge more dioxins than inorganic ones, and that the combustion method in which rapid formation of volatile matter in furnace is controlled to realize the homogeneous mixed state is important for control of dioxins. In the study of non-Br base fire retardant materials, a preliminary experiment was conducted on new fire retardant materials added with inorganic carrier, metal complex, etc. to make the confirmation of fire retardation by liquid phase reaction of polymer in combustion conditions and the study of fire retardation by separating liquid phase reaction, pyrolysis reaction, and gaseous phase reaction. Further, simulation of the combustion of polymer materials was carried out. (NEDO)

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

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

    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.

    Recently several projects have been initiated in Hungary aiming at the introduction of new fuel type, increased maximum allowed power and economic fuel cycle. The planned upgraded power and parallel application of new fuel type require the renewal of the relevant chapter of the Final Safety Analysis Report (FSAR). One of the main tools used for analyzing transient scenarios initiating by reactivity and power distribution anomalies was the ATHLET/KIKO3D coupled neutron kinetic / thermal-hydraulic code. This paper gives an overview of two analyses, which was prepared in the frame of the revision of Paks FSAR, namely the ''withdrawal of one control rod'' and ''initial phase of main steam line break'' events.

    The transient caused by a perturbation of boron concentration and coolant temperature at the inlet of a Russian developed reactor (VVER-440) is reanalysed as a part of the modernisation (introduction of a new type profiled fuel) and power upgrading (up to 108 %) project. This task is one of the basis cases to be investigated in the safety analysis of the pressurized water reactor (PWR) and the criteria of Anticipated Operational Occurrences (AOO) have to be fulfilled for it. First detailed planning calculations were performed with the thermal hydraulic system code ATHLET and neutron physical code system KARATE-440 to find out the appropriate initial parameter set taking into account the active safety system of the NPP. Finally the most reactive case is analysed by the KIKO3D/ATHLET coupled system code. Whereas the investigation is done for safety analysis, conservative assumptions are imposed on reactivity characteristics. Moreover at the core inlet no-mixing is supposed from the unaffected loops. The presented calculations show, how the coupled code system with a detailed description of plant functions and core behaviour can help to understand better the local phenomena in the study of a potential risk of dilution accident, as it offers the possibility to evaluate the plant safety in a more realistic and versatile manner.

    The emerging genome editing technology has enabled the creation of gene knock-in cells easily, efficiently, and rapidly, which has dramatically accelerated research in the field of mammalian functional genomics, including in humans. We recently developed a microhomology-mediated end-joining-based gene knock-in method, termed the PITCh system, and presented various examples of its application. Since the PITCh system only requires very short microhomologies (up to 40 bp) and single-guide RNA target sites on the donor vector, the targeting construct can be rapidly prepared compared with the conventional targeting vector for homologous recombination-based knock-in. Here, we established a streamlined pipeline to design and perform PITCh knock-in to further expand the availability of this method by creating web-based design software, PITCh designer ( http://www.mls.sci.hiroshima-u.ac.jp/smg/PITChdesigner/index.html ), as well as presenting an experimental example of versatile gene cassette knock-in. PITCh designer can automatically design not only the appropriate microhomologies but also the primers to construct locus-specific donor vectors for PITCh knock-in. By using our newly established pipeline, a reporter cell line for monitoring endogenous gene expression, and transgenesis (TG) or knock-in/knockout (KIKO) cell line can be produced systematically. Using these new variations of PITCh, an exogenous promoter-driven gene cassette expressing fluorescent protein gene and drug resistance gene can be integrated into a safe harbor or a specific gene locus to create transgenic reporter cells (PITCh-TG) or knockout cells with reporter knock-in (PITCh-KIKO), respectively.

    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.

    Research and estimation have been carried out on a mechanism to generate methane in paddy fields, which relates closely to global warming. For methane flux measurement, the chamber method was used. The result revealed that with paddy fields mixed with organic substances, methane generation was abundant in the order of raw rice straw mixed area > rice straw compost mixed area > chemical fertilizer mixed area. At the Ryugasaki test area, the raw rice straw and fertilizer mixed areas have generated methane annually at 27.0 gm[sup [minus]2] and 8.2 gm[sup [minus]2], respectively. With regard to soil types, the order was peat soil > gley soil > Kuroboku soil > light-colored Kuroboku soil, where the peat soil generated about 40 times as much of methane as the light-colored Kuroboku soil. As regards the influence from drainage adjustment, normally water-filled field, wet field, and dry field generated methane at 9.25, 4.79, and 0.34 gm[sup [minus]1] y[sup [minus]1], respectively. Amount of methane generated annually from paddy fields over the whole world was estimated at 22 to 73[times]10[sup 12] g. It was determined from the above facts that methane generation may be reduced if organic substance mixing and water in paddy fields are controlled properly. 8 refs., 5 figs., 1 tab.

    This paper reports the result obtained during fiscal 1994 on research on a film forming mechanism for amorphous silicon for solar cells and its quality improvement. In in-situ observation on plasma CVD surface reaction by using the total reflection infrared absorbing spectroscopy, an observation on a real time basis was performed on the reaction process of an a-Si:H surface in contact with gas mixture plasma composed of SiH4 + CH4. In microscopic observation on initial processes of amorphous silicon growth, surface morphological change before and after a-Si:H deposition at 200{degree}C was observed by using an inter-atomic force microscope. The observation verified that a-Si:H has grown to an atomic layer. In research on defect density in a-Si:H fabricated under high-speed film forming conditions, analysis was made on correlation between the film forming speed at 250{degree}C and defect density in the film. Other research works include those on a high-quality a-SiGe:H film fabricated by using the nanometer film forming/hydrogen plasma annealing method, modulated doping into multi-layer films of a-Si:H/a-Ge:H, and thin film transistor using very thin multi layer films of a-Si:H/a-Ge:H. 5 refs., 12 figs.

    The present study is intended to search for living organism deposition inhibiting active materials from the natural environment. Investigation on process of pollution in ocean reveals that adsorption of organic matters called conditioning occurs quickly on the surface, and the surface is covered by biofilms because of presence of bacteria and diatom in the surroundings. After the biofilms are formed, pollution occurs from living organisms, such as acorn barnacles. If the formation of the biofilms being the initial stage of living organism pollution in ocean can be controlled, deposition of large living organisms that follows the biofilm formation was anticipated to be controlled. Searches were made using this possibility as a parameter. The evaluation used a method to measure the antifungal properties specific to the bacteria. As a result of having made searches using this evaluation system, pyridylnitroalkanes were obtained. As compounds like phenethyl amines deeply involving in the deposition phenomenon were obtained, compounds having stronger activity were acquired by synthesizing the derivatives thereof. (NEDO)

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

    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.

    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)

    The trend of technology development, problems harbored therein, trend of the market, and the like were investigated for supporting the development of technologies for the mass production and commercialization of solar-grade silicon materials. Concerning the future of production enhancement and cost reduction in the manufacture of polycrystalline silicon solar cells, studies were made from the technological viewpoint. The results are shown below. It is estimated that approximately 4,500 tons of material silicon will be necessary in 2005 and 6,500-10,700 tons in 2010. Since the melting purification method of NEDO (New Energy and Industrial Technology Development Organization) now under development step by step toward commercialization as well as the conventional source will provide the necessary amount of material silicon, it is inferred that the development of solar cells will go on without any restraint originating in the semiconductor industry. With the commercialization of the technologies so far developed and the development/commercialization of the fast-acting high-performance solar cell technology, probabilities are high that the polycrystalline silicon solar cell manufacturing cost in 2010 will be as low as to be on the 100 yen/W (93-118 yen/W) level which is the level now held up as the goal.

    A research study was done on MHD generation by coal gasificating combustion. MHD generation is a very attractive power generation system such that efficiency is as high as 55%, that preservation of the environment is superior, and that coal can be used as fuel. The open cycle seems suitable for a one million kW class as a base load following up load fluctuation of approximately 20%, while the closed cycle for 200-300 thousand kW class doing daily start-stop. With a mind to a scale of 30 MWt, in the open cycle, R and D is required in such items as a coal gas combustor, generation channel, high temperature air heater, and seed/slag recovery device. In the closed cycle, R and D is required in the generation channel, high temperature helium heater/high temperature valve, seed injection/recovery device, operation technique of helium closed loop, etc.. Moreover, as a total system, development is necessary in the areas of conceptual design and optimization method, partial load operation and DSS operation method, for example. (NEDO)

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

    Efforts are made in cooperation with Vietnam to develop a heat insulating material for buildings, to be used for passive cooling mechanisms symbiotic with the environment and capable of energy conservation. Vegetables are planted on the surface of this building material. Activities are conducted in the three domains of (1) the development of energy conservation-conscious basic materials, (2) selection of vegetables, and (3) the simulation of the effect of the developed materials on temperature. The basic type of the newly developed building material is an asbestos-free vegetable fiber-reinforced cement slate which is covered by such vegetables as members of the Passifloraceae, Vitaceae, and Araliaceae. Conducted in domain (1) are surveys of the actual state of basic material manufacturing in Vietnam and studies of the basic properties of vegetable fiber, properties displayed by vegetable fiber under various chemical environments, selection of vegetable fiber as the basic aggregate, mineral fiber, and the basic material manufacturing conditions. The result of heat load calculation carried out using SMASH for Windows ver.2, which is a program developed for thermal load calculation for houses, shows that the new material lowers the temperature by approximately 3 degrees C.

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

    Research and development was conducted for enhancing productivity and energy conservation by rendering continuous and automatic the electromagnetic casting process for manufacturing polycrystalline silicon substrates for solar cells. In the manufacture of ingots for substrates by continuous electromagnetic casting, the chuck type system for feeding power to the melt plasma was replaced by a roller type system, and the power feeding position was moved to the high temperature region. Also, an on-line ingot slicing technique was established. In the manufacture of substrates at a slicing rate of 300 {mu}m/minute, productivity of 115,000 wafers/month, yield of 98%, and thickness tolerance of 30 {mu}m were achieved. A high-speed cleaning technique was developed using a jet stream, by which the cleaning time was reduced to 5 minutes and the slurry recovery rate was elevated to 95%. Based on these, substrate-related costs in the case of 100 MW/year production was calculated, which resulted in a cost of 98.8 yen/wafer (target: 103.3 yen/wafer) for manufacturing 15 cm square substrates from ingots and in a 15 cm square substrate slicing and cleaning cost of 135.1 yen/wafer (target: 135.4 yen/wafer).

    Innovation plays an important role for Japan to flexibly utilize its achievements for the purpose of properly responding to new business environments and to secure competitiveness in the market. Japan lacks experts equipped with knowledge and ability as regards technology development and management which are necessary for the planning and creation of technologies, and is also short of institutes for raising experts. In America, technology management won an important position in the 1980s in the effort at industrial renovation, and the industry, government, and academia in a body endeavored to elevate the level steadily, continuously, and deliberately, to eventually provide a source of great propulsion and international competitiveness toward today's economic success. Investigations were conducted, and a proposition is made for the establishment of an international technology management research center. Such a center will study technology management and innovation through international exchange based mainly on the industrial circle and through the organic coordination of the industry, government, and academia for widely observing changes in international society for economic frontier cultivation. A practical training and intelligent network will be organized on the global scale, which will serve as an information transmitter. A skeleton of the plan is shown. (NEDO)

    The micro pan-tilter and focusing mechanism can adjust focuses while changing freely the visual axis by using a super small CCD micro camera of 9.2 mm in a diameter times 27 mm in length, and contains a camera control unit (CCU) in this size. Many functions of a camera with a tripod head are concentrated into a size 1/10 of that of conventional cameras. The mechanism has been developed for a micro robot to inspect interior of small pipes in devices such as heat exchangers in a power plant. Future application is expected to medical endoscopes and portable information devices. This mechanism observes forward distant view and side wall short-distance view with the maximum resolution of 20 {mu}m by coordinated operation of three high-torque static power drive motors (with minimum outer diameter of 2.5 mm) fabricated by using the micromachine technology. Auto-focusing is also possible. The hybrid IC built-ion CCU has been realized by using the three-dimensional high-density mounting technology. Part of this research and development is performed under the industrial science technology research and development institution established by the Agency of Industrial Science and Technology of the Ministry of International Trade and Industry.

    With an objective to clarify the interactions between micropore structure of coal and solvent reagents, a sorption experiment was carried out under solvent saturated vapor pressure. Low-volatile bituminous coal, Pocahontas No. 3 coal, has the aromatic ring structure developed, and makes solvent more difficult to diffuse into coal, hence sorption amount is small. Methanol has permeated since its polarity is high. High-volatile bituminous coal, Illinois No. 6 coal, makes solvent penetrate easily, and the sorption amount was large with both of aromatic and polar solvents. Since brown coal, Beulah Zap coal, contains a large amount of oxygen, and hydrogen bonding is predominant, sorption amount of cyclohexane and benzene having no polarity is small. Methanol diffuses while releasing hydrogen bond due to its polarity, and its sorption amount is large. A double sorption model is available, which expresses the whole sorption amount as a sum of physical sorption amount and amount of permeation into coal. This model was applied when it explained successfully the sorption behavior of the solvents relative to coals, excepting some of the systems. However, also observed were such abnormal behavior as sorption impediment due to interactions between coal surface and solvents, and permeation impediment due to hydroxyl groups inside the coals. 1 ref., 10 figs., 2 tabs.

    Although the synthetic dyes and pigments originating in the 19th century are now at the height of their prosperity, there is an earnest hope for technology for realizing `supercolor.` If it is presumed that the features of such supercolor are to be found in outstanding clearness and high resistance to fading in the presence of ultraviolet rays, etc., the supercolor will be quite tough to deal with. When attention is steered toward the living world, however, there are cases of easily producing such by morphogenesis at the level of several tens of nanometers. In this paper, the development of a novel material is presented from the viewpoint of biomimetic engineering that the author et al. are engaged in. The coloring on the wings of a butterfly Morpho Sulkowskyi of South American origin is the product of interaction between light and the physical, microscopic structure of scales, and the coloring is extremely clear and remains free of fading except in case the microstructure is destroyed. This mechanism is applied for the development of a supercolor fiber. As the result, a structurally coloring fiber is created by stretching a molten composite string. In this effort, reformed polyester and polyamide different in refraction factor are used in place of substance layers and air layers on the butterfly wings. (NEDO)

    The thermal stress analysis within lump coke was studied in order to investigate macro-crack formation and deformation behavior which strongly influence heat and mass transfer in a coke oven chamber. The dilatation of plastic layer, heating rate dependence of thermophysical and mechanical properties of coal/coke, creep in the plastic and semi-coke layers, macro-crack propagation and radiative heat transfer within the macro-crack were considered in an analytical model. The macro-crack propagation was determined from the estimated crack tip stress intensity factor, K{sub I}, at the macro-crack tip compared with the plane strain fracture toughness, K{sub IC}, through the unsteady-state calculation. Calculated results on crack formation and deformation behavior of lump coke were in good agreement with experimental observations in a laboratory-scale oven chamber. The analytical model could predict micro-crack formation within the lump coke normal to the heated wall and the coke surface close to the heated wall. 12 refs., 13 figs.

    An investigational study was made for large-scale tree-planting aiming at CO2 fixation. Water resource and precipitation relating to tree-planting were determined from NASA data and arranged into the global distribution map. It was found that Australia and the Chinese continent are under the relatively favorable condition. As for the soil condition, nutrition resource is short in the desert and unused zone. From the vegetation data obtained from meteorological satellite NOAA, developed was a method for estimating net primary productivity of terrestrial ecosystem and obtained was a global distribution map for the amount of CO2 fixed under the present terrestrial vegetation. At the same time, areas which have great potentiality of tree-planting were selected from the map for estimating potentiality of the global tree-planting. To study the promotion of rainfall as a means of expanding the potential tree-planting area, the conventional meteorological and physical model was improved, and more realistic simulation was made possible. Also as to the water utilization technology, the modeling method was developed. As the area having a potentiality of expanding tree-planting, Australia (especially the west) was cited as the first candidate, and China the second candidate. 108 refs., 128 figs., 49 tabs.

    In this study, in a magnetic levitation system using pinning force of high temperature superconductors, for a propose of magnification of the stable contactless gap length and exclusion of mass regulation of a floater, a magnetic levitation model was improved. That is, the tangential component of an attractive force between a high temperature superconductor where magnetic flux was pinned and magnetic material is used for levitation and stable force in up and down directions, and restoring force generated due to pinned flux gathering was used for horizontal stabilization. For a floater made by using this principle, weight addition was necessary for letting the center of gravity down, however self-weight regulation of a floater is originally unnecessary. Thus, a magnetic levitation apparatus can be made without self-weight regulation of suspension and having a wide stable gap by using this levitation method. Since the floater was constructed under two rails, there are good points on easily dealing with the safety countermeasure in cases of which levitation would reduce or disappear. 4 refs., 7 figs.

    During a single-cell disassembly test of molten carbonate fuel cells having been operated for 90 hours to 5500 hours, correlativity was discovered between decrease in the retained amount of electrolyte due to decrease in pore capacity of electrodes and electrolyte plates and the electrolyte loss. The electrolyte loss amount cannot be explained with the conventional mechanisms, thereby a new model was proposed. The cathode has shown very little change in the capacity change in pores with diameters smaller than 2 {mu}m per unit area. The anode has remained almost constant after 1000 hours, but the electrolyte plates have shown remarkable decrease. Therefore, it is possible to estimate that the electrolyte plates should have been the major cause for the electrolyte loss. The result of measuring the electrolyte loss amount agreed well with that estimated using pore capacity curves. This fact suggests that the electrolyte loss can be explained by a new mechanism that hypothesizes the existence of a largest size of retaining pores that can support carbonates and defines that the electrolyte loss is generated from decrease in the pore capacity. 7 refs., 8 figs., 1 tab.

    This project is aimed at construction of the system which can provide information after searching in realtime key words in a vast volume of reports by Intergovernment Panel on climate Change (IPCC) and answers to Policy Relevant Questions (PRQ). The technical terms appearing in scientific documents use few synonyms to avoid ambiguity, and analysis of frequency of keywords is expected to be an index which provides important information. The chapters in the IPCC reports are not independent but coordinated with each other. It is therefore considered that analysis of the inter-chapter structures based on the keyword frequency analysis provides the meaningful viewpoints for, e.g., understanding Third Accessment Report (TAR) and extraction of the future research themes. For analysis of the logical structures of the sentences containing the keywords, special attention is focused on the term (sustainability) as the most important keyword in TARs, and its logical structures are analyzed. It is decided that the answers to PRQ are extracted from TOD. (NEDO)

    A deodorant filter was made by treating porous metallic iron with an L-ascorbic acid aqueous solutions depositing the iron ascorbate on it. The ammonia adsorption capacity of the deodorant filter was studied with repetitive runs of adsorption tests. The results show that the ammonia adsorption capacity of the iron ascorbate is nearly equal to conventions: granular activated carbon at the beginning, but unlike the letter, the iron ascorbate perfectly recovers the capacity via reversible desorption. ESR and Mossbauer spectroscopy reveal that ammonia goes into the inner coordination sphere of Fe(II) and Fe(III), capable of reversible adsorption and desorption, and that the reactivity of iron is attributable to the formation of the ascorbate complex, which is formed in the specific manufacturing process of the deodorant filter. 13 refs., 7 figs., 1 tab.

    This is No.91 report of National Institute for Research in Inorganic Materials, concerning cobalt oxide. For the growth of single crystal by the Czochralski method, shape of interface and contamination of impurities are affected by the convection of molten liquid in the atmosphere. Various oxides besides CoO were investigated. Solid solutions of Cr2O3 and Al2O3 into CoO were also studied. Non-linear optic and dielectric properties of single crystals, such as Ba2NaNb5O15 and LiNbO3, were examined. It was considered that the positive electron having positive electric charge can be used for the study on the negative electric charge defect in materials. However, the positive electron itself is rare, which results in the too low efficiency of measurement. Efficiency improvement of 50 times was achieved by introducing a high performance 2D position detector, which was still low efficiency of one-hundredth compared with photoelectron spectroscopy. It was found that the aggregation structure of positive ion defects in CoO is a misunderstanding of phenomenon caused by the electronic state in bulk crystals. As a result of the study on the optical properties of f-electron transition metals, transparent ceramics with addition of various rare earth ions were described. 162 refs., 106 figs., 14 tabs.

    Sinters of silicon nitrides have excellent properties as a structural material, but their technological repercussion effect is not as much as has been expected. The cause is in insufficient understanding on the mutual relationship between microstructures and mechanical properties. Therefore, methods of controlling structures were first discussed in the studies on synthesis of high-tenacity ceramics. In order to achieve high reliability in material strength, discussions were given on means to have a structure developed with high reproducibility. Development was performed on {beta} powder which shows no abnormal grain growth and is stable at elevated temperatures. Then, quantitative evaluation was made on factors to manifest a self-compounding structure with columnar particles grown in ultrafine particles. The relationship between its chemical composition, microstructure and mechanical properties was also discussed. Particle shapes of silicon carbides and their fracture tenacity values were considered theoretically by using a drawing model. To evaluate the microstructure, it is important to determine the grain boundary composition, whereas an electric field radiation type high-performance electron microscope was developed. In discussing the fracture mechanism, a model was structured for behavior of covalent binding crystals against external stress. 164 refs., 95 figs., 10 tabs.

    This paper illustrates the results of field tests conducted as a basic investigation of electroseismic phenomenon at the site of Kyushu University. The electroseismic phenomenon is a physical phenomenon in which electromagnetic response is derived by the incident elastic wave in the underground. According to Karl E. Butler, et al., mutual motion occurs between rock matrix and pore water by the propagation of P-wave in porous media. Spatial change in the water content per unit volume occurs, which is similar to the density change with the propagation of P-wave in elastic solid. Since the pore water with mobility can bring charges generated in the electrical double layer, the change in the water content agrees with the density change. Accordingly, domains of positive and negative overcharges are generated at the top of P-wave, which can be a current source. An electric field is generated between the domains. As a result of the field tests, it was confirmed that electromagnetic phenomena can be derived by the elastic waves. 2 refs., 8 figs.

    This paper describes attempts of establishing an oil recovery technology utilizing microorganisms and of aiming at improving the practicability of that technology. Fiscal 1994 has investigated effects of inorganic salts existing in reservoir beds and NaCl concentrations on proliferation of microorganisms and production of metabolites. The investigation was intended to discuss applicability of microorganisms to environments that are brought closer to actual field conditions. Furthermore, a core sweeping test using sandstone was carried out on the fiscal 1992 separated bacteria, the 4118 bacteria, that has high surfactant production capability. In addition, a sand pack was used to perform a flooding experiment under conditions of 50{degree}C and 50 KSC to evaluate functionality of microorganisms when environments in the reservoir bed are simulated with respect to pressures and temperatures. An oil recovering experiment was carried out using a sandstone with a diameter of 1.5 inches, a length of 1.0 foot and permeability of 600 md, and using Bacillus subtilis 4118 bacteria which attained the lowest interfacial tension among the bacteria examined. A recovery rate of 4.4% Sor was derived in the experiment. A recovery rate of 29.0% Sor at maximum was obtained when Bacillus licheniformis 18-2-a bacteria was supplied into a sand pack filled with silica sand. 20 figs., 7 tabs.

    Study was made on the storage method of a methane component in biogas mainly composed of CO2 and methane gases. Methane clathrate as molecular complex is one kind of clathrate compounds. Eight methane gas molecules are absorbed into 46 water molecules, or methane gas of 216 l is absorbed into water of 1 l, resulting in considerable compact methane storage. Although methane clathrate is usually stable only under a condition of low temperature and high pressure, its formation equilibrium shifts toward a low pressure/high temperature side by adding additives such as amine, ether and ketone. Acetone can shift formation pressure from 30 to 10atm at 1degC, and formation temperature from 1 to 10degC at 30atm. Although methane liquefaction is also an efficient storage method, it requires liquefaction temperature and pressure of -83degC and 45.6atm, respectively. The distance between methane molecules in clathrate lattice can be more shortened than that in high- pressure charged gas, suggesting higher storage efficiency. The study result showed that the handling of methane clathrate is possible around room temperature and pressure. 7 refs., 5 figs.

    Acid fog research was behind in comparison with acid rain research. In case of acid fog, it is because the place generating sufficiently thick fog to collect is limited, the generating place is mountainous, its survey needs a lot of works, its collector is not convenient like in acid rain, or its sampling is difficult on its automation. Since the 1980s, an extensive survey on acid fog had been carried out centering the west coast of California, USA, and low pH fog (minimum pH 2.2) was observed. In the course of these researches, string type active fogwater collectors became a major sampling method, and the simulation of acidification of fog droplet in the atmosphere was extensively conducted. In Japan, already in the 1960s, field surveys on acid fog were conducted, in 1984 acid fog survey started on Mt. Akagi under a viewpoint of ecological impact, and there was a report that low pH fog (pH 3 to 4) continued more than 10 hours. It was pointed out that there were plant damage by acid fog in several locations, especially the tree mortality mechanism in Tomakomai was clarified. 50 refs., 10 figs., 6 tabs.

    Chemical sensor is made of up transducer that transfers the part and signal recognizing the measurement objects. Biosensor that normally transfers the amount of chemicals into electrical signal is a sensor in which living materials like enzyme, microorganism or antigen, antibody and so forth are used in the recognition part. Recently, the structure or the function of the living materials is clarified gradually with the significant progress in biofeedback, however, the synthesis of artificial material having same function as that of living materials is extremely difficult. Accordingly, it is very practical to develop high degree sensor function by using living materials with developed function in material recognition part, an important element of the sensor. In this report, solid state biosensor using electrode as a transducer is focused, and specially, recent research progress regarding the amperometric measurement which measures oxidation/reduction current is discussed. 35 refs., 8 figs., 1 tab.

    For the establishment of a practical process for substitute natural gas (SNG) production, technological and economical assessments were made, and tasks to discharge for the development were discussed. In this fiscal year, the results of surveys conducted in the past five-year period were compiled, and studies were made to prepare for a smooth transition to the element research stage. Findings obtained are described below. SNG producing technologies need to be developed, with the demand for SNG increasing sharply, to further stabilize the base for SNG supply; coal which is abundantly available should be used as the material for SNG; and coal hydrogasification, among various methods for producing SNG from coal, is the most suitable in view of efficiency and cost performance. It was also found after a prolonged study for the improvement of efficiency and cost performance that probabilities were high that the yield of BTX (benzene, toluene, xylene) would increase and cost performance would improve. Besides, a basic plan and an element technology research plan were prepared for the development of the ARCH (advanced rapid coal hydrogasification) process. (NEDO)

    The renin-angiotensin system (RAS) plays an important role in the regulation of blood pressure. In order to clarify the signaling mechanism mediated by angiotensin 2 receptor, Gq-protein binding amino acid residues of this receptor were clarified by site-directed mutagenesis study. Amino acid residues in the carboxyl tail region were changed by alanines, individually. These mutated receptors were expressed stably in CHO cells, and GTP effect and second messenger molecules were determined, and three residues (Y 312, F313 and L 314) in this region were determined to be concerned for the binding of Gq protein. The other signaling systems, Gi, MAP kinase, JAK-STAT mediated, were reported to be concerned for this receptor. Novel drags for high blood pressure therapy would be explored by clarifying these signaling mechanisms. (author)

    Assessment and examination were conducted on the scientific/technological aspect, environmental aspect and economic/social aspect concerning measures for mitigating climate change, as a part of international cooperation in global warming issues. In the development of assessment methods for cost analysis, it revealed that, in the activities for mitigating emission of greenhouse effect gases (GHG) or for increasing carbon sequestration, benefits of the mitigation sometimes surpassed their cost, allowing the society to benefit from the mitigation. In the examination of problems in technology transfer and their solutions, it was found that, in order to attain successful transfer, partnership among the parties interested was essential and that each government was capable of promoting such partnership. In the assessment of various policy options, the situation in the U.S. is such that the market aspect of GHG emission permit and credit trading is rather weak because of immaturity in a legal framework on GHG emission trading and because of undefinedness in the systems of the Kyoto Protocol and in the possibility of its validation. However, the reason enterprises are actively participating in the early market is that they plan a risk-hedge for example in anticipation of tighter regulations in the future. (NEDO)

    The International Conference on Adaptation and Mitigation Technologies for Climate Change was held based on the 1st Conference of the Parties in 1995 of the United Nations Framework Convention on Climate Change, and the 2nd evaluation report of the Intergovernmental Panel on Climate Change (IPCC). This report carries the outline of this conference and minutes. Japanese government had studied the framework of activities implemented jointly (AIJ) for emission control of greenhouse gases by voluntary workers jointly with developing countries. The government decided the basis of the AIJ Japan program in 1995, and approved the evaluation guidelines of this program including confirmed and considered matters which are necessary for government offices related to this program to evaluate and approve each project. IPCC approved the 2nd evaluation report in its general meeting in 1995. This conference was thus held to discuss strategic technology and international cooperation with participation of writers of the 2nd IPCC report, policy planners of Asian countries, Japanese industries, governmental offices and NGO.

    As a part of the international cooperation for the global warming problem, evaluation/study were conducted on policy to lessen climate changes from viewpoints of scientific technology, environment, and economy/society. In the development of evaluation methods on cost analysis, the following were pointed out: Changes in resource utilization brought about as a result of the policy are all needed to be numerated; In resource, clean air and water, and also abolition of price barrier and prices now in force are included. As subjects on the technology transfer, cited are barriers in aspects of organization/system and barriers in aspects of economy/finance and society. Especially, it was pointed out that it is necessary to exchange the persons concerned in the industrial sector. Of various optional policies toward the prevention of global warming, the Kyoto mechanism not only has an economical merit of the use of low cost option but can be fairly promising from an environmental viewpoint of internationally controlling the greenhouse effect gas emission, if the characteristic of practically using the market can be so designed that it fulfills its function.

    Generally, a high specific speed diagonal flow fan with a small pressure rise coefficient has a slight positive gradient part of the pressure rise - flow rate characteristics. In addition, the pressure fall is small, between the flow rate at which the impeller stall in the throttle closer and the stalling flow rate. In the case, Kaneko et al. suggest a way of improvement on performance characteristics by an inlet annular wing which removes a low-momentum fluid from a rotor tip region. However, in case of a fan that has a sharp drop of pressure rise in the stall characteristics, it is not clear that the stall characteristics can be improved by this way. In this study, in order to improve the unstable characteristics of a high pressure rise coefficient diagonal flow fan, Tip clearance flow has been investigated on five rotor-casings with various holes to bleed low-momentum fluid in the range of flow rate from design point to stall point.

    Corrosion behavior of hot-dip Zn-6%Al 0-3%Mg alloy coated steel sheets in cyclic corrosion test (CCT) has been investigated. The corrosion resistance was improved with increasing Mg content in the coating layer, and the highest corrosion resistance was observed at 3% Mg. In Zn-6%Al-3%Mg alloy coated steel sheet, the formations of zinc carbonate hydroxide and zinc oxide were suppressed for longer duration compared with Zn-0.2%Al and Zn-4.5%Al-0.l%Mg alloy coated steel sheets. As a result, zinc chloride hydroxide existed stable on the surface of the coating layer. From the polarization behaviors in 5% NaCl aqueous solution after CCT, it was found that the corrosion current density of Zn-6%At-3%Mg alloy coated steel sheet was much smaller than those of Zn-0.2%Al and Zn-4.5%Al-0.1%Mg alloy coated steel sheets. As zinc carbonate hydroxide and zinc oxide had poor adhesion to the coating layer and had porous structures, these corrosion products were considered to have little protective action for the coating layer. Therefore, it was concluded that Mg suppressed the formation of such nonprotective corrosion products. resulting in the remarkable improvement of corrosion resistance. (author)

    It is suggested that methyl mercaptan is decomposed to methyl sulfide and hydrogen by reaction with the a-iron hydroxide, and then the methyl sulfide combines with sulfur crystal and the hydrogen changes into water by the chemical reaction with the {alpha}-iron hydroxide. A deodorant filter was made by treating porous metallic iron with an aqueous solution of L-ascorbic acid, iron (II) sulfate and calcium hydroxide aqueous solution to deposit the iron ascorbate and the {alpha}-iron hydroxide on it. Then the deodorant filter was exposed to the hydrogen sulfide to yield the sulfur crystals on the surface of the deodorant filter. The methyl mercaptan removal capacity of the deodorant filter was studied with repetition of removal tests. Results show that the methyl mercaptan removal capacity of the deodorant filter is a little smaller than that of conventional granular activated carbon. 6 refs., 6 figs., 3 tabs.

    This research and development is intended to establish a basic technology related to high crystalline polymeric material that has dynamic properties comparable to metallic materials by single polymeric material as a structural material. Thick and large high-elasticity molded forms were obtained by searching poly-arylate material, and by developing such processing technologies as high-pressure injection molding, composite injection molding, and elongation fluidity molding. High-elasticity molded forms with uniform internal orientation were obtained by heating and molding liquid crystal polymers under high magnetic field. Solution molding was performed on a molecular composite consisting of rigid chains and soft chains, which was laminated and bonded to have obtained an isotropic form with as high elasticity as 54 GPa. In addition, high pressure powder formation of cross-linked polymers of di-acetylene system provided an isotropic form with sound wave elasticity of 23 GPa.

    For contribution of suggestions for establishing directions and concrete tasks for new industrial technology research and development projects, a survey is conducted about trends of industrial technology development and into research domains where importance will gather in the future, for which development trends are studied such as limiting, providing of intelligence, and advanced composition. In this report, domains expected to become important in the future are investigated. Important subjects are found in the domains of the space limiting (micromachining, atom/molecule manipulation, microanalysis, etc.), the time limiting (super-spacetime processing, quantum device, femtosecond technology, 4-dimensional device, etc.), biomimetics and providing of intelligence (intelligent material, neural network, genetic algorithm, artificial life, sensor fusion, intelligent robot, etc.). In addition to these, 'ultrastructure that learns from organisms,' 'intensive interaction system,' and 'nonlinearity/chaos technology' are proposed as promising fields of development. Since Japan is traditionally strong in hardware technologies relating to micromachining and substance/material processing, good results will be attained when the industrial, governmental, and academic circles exert endeavors.

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

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

    The ceramic gas turbines (CGT's) for, e.g., cogeneration and portable power generation systems are studied and evaluated for their environmental preservation, energy saving and economic characteristics. Types of utilization and market sizes are also studied for, e.g., portable power generation systems. The items studied include current status of cogeneration systems in USA, and recognition of cogeneration systems in Japan. The study results lead to the conclusions that the biaxial CGT for portable power generation systems is a promising substitute for diesel engines as the power source in the future, and 300kW class CGT's will have the markets of 170,000 units and potentially 450,000 units, because of their expected wide applicability. The studies on their economic, energy-saving and environmental load reduction effects indicate that one unit brings the economic effects totaling 616,000 yen, due to reduced fuel consumption and NOx abatement. They could reduce NOx emissions by 8,090 t/y for automobiles and 6,570 t/y for the others, when they fill the potential markets. (NEDO)

    This paper reports the result obtained during fiscal 1994 on research on research on optimization of bandgap in thin film compound solar cells. In research on Cu(InGa)Se2 thin film solar cells by using a gas phase selenide making process, discussions were given on optimizing the following three processes: a process to raise temperature of a precursor film formed at a substrate temperature of about 150{degree}C, a selenide making process to perform annealing at about 500{degree}C, and a temperature reducing process. Good characteristics were obtained when selenium amount in the precursor is about 50%. In a bandgap control viewpoint, it was found that the conversion efficiency decreases rapidly when Ga composition is higher than 50%. A conversion efficiency of 14.9% was obtained to date at the Ga/(In+Ga) ratio of 0.4. In research on Cu(InGa)Se2 thin film solar cells by using a simultaneous deposition method, a conversion efficiency of 13.5% was obtained at a bandgap width of about 1.3 eV during research on manufacturing ZnO/CdS/Cu(InGa)Se2 thin film solar cells by using the simultaneous deposition method.

    Described herein are the results of the FY1994 research program for research on advanced solar components as part of research and development of solar thermal energy. The catalyst for liquid-film reactions is prepared, and the flask tests are conducted as the preliminary experiments for development of the reactor in which 2-propanol is fallen in liquid film over the catalyst dispersed to accelerate its decomposition. It is decomposable when fallen in liquid film even in the presence of 35% of acetone. The catalyst of ruthenium carried by activated coal is used to produce 2-propanol under an exothermic condition from acetone and hydrogen. Diisopropyl ether and 4-methyl-2-pentanone are produced as by-products, when the reactor tube is kept at 140 to 200{degree}C at the external wall, diminishing as temperature is increased. There is a temperature differential of 20 to 30{degree}C in the reactor tube between the center axis and external wall. 3 figs.

    This paper reports the result obtained during fiscal 1994 on research on a technology of low temperature deposition of polycrystalline thin films for solar cells. This research used ITO coated glass substrates, on which CdS was accumulated to a thickness of about 100 nm by using the CBD process, and over this deposition a CuInSe2 film was formed at 300{degree}C by using the ion cluster beam (ICB) process. The manufactured solar cells with a glass/ITO/CdS/CuInSe2/Au structure had an efficiency of 2%. In manufacturing a CuGaSe2 thin film by using the ICB process, effects of acceleration voltage relative to cluster beams and ionization current were investigated. It was found that the film morphology, the result of analysis by using X-ray diffraction, and the electric conductivity are sensitive to the ionization current. From these findings, an optimum film forming condition was derived. A CuGaSe2 thin film was manufactured by using the ICB process over a Cds thin film deposited by using the CDB process. Both of the surface morphology and X-ray diffraction patterns of the film did not show a large change, indicating a possibility of manufacturing cells with a reverse structure. Effects of heat treatment on CuInSe2 monocrystals were evaluated by using ESR and FTIR. 6 figs., 1 tab.

    This paper reports the result obtained during fiscal 1994 on research on interface of amorphous silicon for solar cells. In research on amorphous solar cells using ZnO for transparent electrically conductive films, considerations were given on a growth mechanism of a ZnO film using the MOCVD process. It was made clear that the ZnO film grows with Zn(OH)2 working as a film forming species. It was also shown that the larger the ZnO particle size is, the more the solar cell efficiency is improved. Furthermore, theoretical elucidation was made on effects of rear face of an interface on cell characteristics, and experimental discussions were given subsequently. In research on solar cells using hydrogen diluted `i` layers, delta-doped solar cells were fabricated based on basic data obtained in the previous fiscal year, and the hydrogen dilution effect was evaluated from the cell characteristics. When the hydrogen dilution ratio is increased from zero to one, the conversion efficiency has improved from 12.2% to 12.6%. In addition, experiments and discussions were given on solar cells fabricated by using SiH2Cl2. 9 figs.

The process is composed of three elements: smelting reducing furnace, preliminary reduction fluidized bed, gas reforming furnace. Making mathematical models as a means of study of the process, material balance and heat balance are calculated. Operational unit requirements are estimated, changing them in the range of 20-60% of the post combustion based on three fundamental processes each of which is composed of one or a combination of the three elements. The total cost is also trially calculated, estimating fixed cost including installation cost, etc. With no big differences in the iron-melting cost excluding by-products in each process, the cost may be reduced by 5-10% of that in the blast furnace process. The elementary study has continued almost satisfactorily and attained the expected target, though there still remain some problems. In 1990 the study started of a pilot plant with a 500t/day capacity. 12 figs.

    For solving the global warming problem and constructing the resource recycling society, a demand for highly recyclable light-weight Mg alloys is increasing for energy saving and recycling improvement, in particular, for automobiles and electrical appliances. However, use of Mg materials is limited because its poor workability. This research targets development of the material with a rich recyclability and a rich workability for forming complex shapes, and its working technology. Leading research was made on development of the continuous high-strain rate (more than 10{sup -2}/s) super- plasticity material forming process from raw materials to products of Mg alloys, and establishment of the production technology free from technological barriers. The research result showed that for the recognition of Mg alloy as low- environment load super light-weight industrial material, establishment of the composite resource-saving energy-saving production process including recycling and reusing is necessary at the same time as establishment of the high- strain rate super-plasticity material forming process.

    This paper reports the result obtained during fiscal 1994 on research on surface passivation of high-efficiency silicon solar cells. In research on carrier recombination on SiO2/doped silicon interface, measurements were carried out on minority carrier life with respect to p-type silicon substrates with which phosphorus with high and low concentrations are diffused uniformly on the surface and non-uniformly on the back and then oxidized. The measurements were performed for the purpose of evaluating the carrier recombination at p-n junctions. Effective life time of oxidized test samples increased longer than that of prior to the oxidization as a result of effect of surface passivation contributing remarkably. In research on reduction in carrier recombination on SiO2/Si interface by using H radical annealing, experiments were conducted by using a method that uses more active H-atoms. As a result, it was revealed that the reduction effect is recognized at as low temperature as 200{degree}C, and photo-bias effect is also noticeable. Other research activities included analytic research on minority carrier recombination on micro crystalline silicon/crystalline silicon interface, and experimental research on evaluation of minority carrier life of poly-crystalline silicon wafers. 6 figs.

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

    This paper evaluates influences of stacking of incident angles against the reflecting surface on the resolution. Basic equations for evaluating the influences were deduced. A simple evaluation method has been provided using these equations. The present evaluation method is considered to be useful for acquisition design, processing, and interpretation of data as an indicator. According to the equations introduced in this study, there are some demerits for stacking traces whose incident angles were large. A total reflection region often appears due to the decreased resolution, and the vertical resolution decreases prior to stacking. Occasionally, it is not effective to remove traces having large incident angles from the viewpoint of resolution. In practice, the selection of most suitable trace through trial and error is not easy due to difference in individual regions. An evaluation method must be discussed, by which the optimal trace can be selected automatically during the data processing. 6 refs., 15 figs.

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

    In the conversion from solar energy into chemical energy (fuels) by photochemical conversion, an electron donor is necessary since all the fuels are reductive compounds. From the viewpoint of economic profit, water is the only one candidate as a cheap compound and existing impartially. In this paper, photosynthesis as well as the realization of its artificial model, and the relevant basic research executed recently aiming at the construction of an artificial photosynthetic system are explained. The main reaction of photosynthesis is the generation of carbohydrates by the reduction reaction of carbon dioxide with water as an electron donor and solar visual light as an energy resource. As a special example thereof, the UV photolysis of water due to the photocatalysis of a micro-particle system is introduced. The method of using a semiconductor and the method of using sensitizes are described as the photo excitation system when designing the artificial model. Additionally, as the research with respect to the construction of an artificial photosynthetic system, a photo-exciting charge transfer system is introduced. 27 refs., 1 fig.

    As measures for the spots difficult in metering within a framework to integrally automate the power distribution, a remote reading system was prototypically tested and evaluated in reliability on the actual field. The system methodically selected the signal {prime}s line injection, high frequency wave signal and voltage detection, while the signal frequency, transmission rate and highest transmission output were set at approx. 3.5KHz, 7.5bps and 50dBm, respectively from the test result. The demonstration test on reliability of the system locatively selected a vicinity of high voltage consumer, high harmonic wave-generating consumer, transforming station, etc. The total ratio of success in reception was comparatively high in Kuzuno and Yamazaki areas, but low in Kamojyo and Ichinomiya areas, The badness in reception was caused by the fluctuation in noise and strongness in damping which was influenced by the condenser in the high voltage consumer. The locative relation between the parent and child stations of system, and high voltage consumer being classified into four patters, an application table of remote reading system was prepared by simulation. 14 figs., 6 tabs.

    Study of metamorphic belts and tectonics is introduced. Minerals supposedly originating in the transitional zone and the lower mantle, that is, inclusions in diamond in kimberlite, are deemed to carry information about the depth level of 670km and lower. The place of origin of peridotite, Alpe Arami of Switzerland, is again estimated at a level of 300km or deeper. In the tectonic cross section in this region, the oceanic crust is bent and folded, and such a structure enables the supposition that fragments off the transitional zone may be carried upward to the ground surface. This region is now being limelighted, with plume tectonics enjoying popularity. The split of Pangaea is related with the ascent of plume.

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

    Some sulfides containing silver show high ion mobility based on movability of silver, whose application is expected. Studies have been carried out centrally on synthesis of new compounds of ternary silver sulfides by elucidating the relationship among their compositions, structures and properties by means of crystal chemical studies mainly on their phase relationship. A few new compounds have been synthesized, such as the ones having the argyrodite family compound structure including transition metals. The synthesizing process takes a kind of turbulent liquid state structure at elevated temperatures because of movability of silver, but silver is fixed at low temperatures in different sites between skeleton structures made by other atoms. These studies on phase transfer, structures, and silver movability have been based on X-ray diffraction, infrared and Raman spectroscopic measurements, NMR, measurements of electric and thermal characteristics. For the studies related to compositions and structures of ternary metal sulfides which take compound crystalline structure, a structure analyzing method based on multi-dimensional hyperspatial groups was used. This paper reports the summary of the studies in seven chapters, and dwells on the remaining problems and future prospects. 158 refs., 114 figs., 65 tabs.

    The water tank test of marine structures or submarine structures uses a wave maker to generate waves. A typical flap wave maker uses the wave making flap penetrating a water surface whose bottom is fixed on a tank bottom through a hinge, and the top is connected with a rod driven by rotating servomotor for reciprocating motion of the flap. However, this driving gear using a rotating servomotor and a bowl- screw has some defects such as noise caused by bowl rotation, backlash due to wear and limited driving speed. A linear motor with less friction mechanisms was thus applied to the driving gear. The performance test result of the prototype driving gear using a linear motor showed the possibility of the linear driven wave maker. The linear driven wave maker could also achieve low noise and simple mechanism. The sufficient durability and applicability of the linear driven wave maker mechanism were confirmed through strength calculation necessary for improving the prototype wave maker. 1 ref., 5 figs., 2 tabs.

    This paper describes course of pneumatic technologies and problems in future researches. Pneumatic systems are inferior to electric and hydraulic systems in terms of efficiency. It is because electric power is converted into fluidized energy by using a compressor, and then converted to mechanical energy by using an actuator. When theses published from 1990 through 1999 are put in order, the research objects are accounted for half by control related technologies, and researches related to elements account for only one third. This paper enumerates assignments to be tackled positively in the future by utilizing compressibility of air in pneumatic systems, and features of high speed drive utilizing the stored energy instantaneously. Application of air pressure to robotics from the demand of the aging society, and pneumatic tools having intelligent functions must be subjected to new contrivances. These will serve for work assistance systems to enable aged people to perform works, and for activating industries including organic agriculture. Tools in this sense may include impact wrench, and others. Furthermore, development of fundamental studies for 'why air pressure?' is demanded strongly, including the viewpoint of LCA in the recycling type society. (NEDO)

    The Research Group on Earthquake Ground Motion in Sapporo City established in May 1996 has inaugurated collection of information on ground structures and observations of strong earthquakes in Sapporo City. The Research Group on Earthquake Ground Motion in Sapporo City has carried out geological investigations, electric logging and PS logging to date in three boring holes each with a depth of about 100 m, 200 m and 600 m. According to the result of the logging in the new Ishikari Bay port (600-m deep hole), the S-wave velocity has increased slowly as it starts from the ground surface to greater depths, but showed no noticeable velocity boundaries in this range of the depth. The Sapporo municipal office has drilled three observation wells (500-m deep) for the purpose of determining focal points of microtremors directly under the city area. Hole-bottom observation has been inaugurated since the beginning of this year. According to comparison of the results of loggings at great depths, a depth at which the S-wave velocity reaches about 700 m/s becomes greater toward the sea area. The result of calculations on amplification characteristics of the SH wave on rock beds revealed that a seismic wave of about 0.5 Hz is amplified by a little more than two times. 1 ref., 5 figs., 1 tab.

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

    In order to demonstrate the power transmission using microwave and arrange advantages and problems in the wireless power transmission, field tests of point-to-point power transmission were conducted. Microwave frequency of 2.45 GHz was used, which is assigned as the industrial, scientific and medical frequency. The transmission system is composed of generator, director tube, primary radiator, and transmission antenna. The maximum 5 kW of microwave power can be transmitted by combining a 3 m-diameter parabolic antenna and a magnetron. The receiving system is composed of devices called as RECTENNA (rectifying antenna). A large capacity and high efficiency RECTENNA was developed, by which the maximum 2.5 W of input power per single device can be provided. As a result of the experiments, efficiency at the transmission side was over 70%, and RF-DC efficiency at the receiving side was about 51%. At the open-air test site, however, the total efficiency of only 14.8% could be obtained. 8 refs., 12 figs.

    This paper described the researched results of the demonstrator of a turbofan engine for supersonic aircraft (IHI-17). A turbofan engine with an afterburner was experimentally fabricated and various engine tests have been carried out since 1988. Although the engine size is small, the fighter engine specifications were applied to its design and the prior or simultaneous research on each component was carried out. As a result, the system integration technique by which an engine was assembled by integrating each component could be established. New materials and new manufacturing techniques such as turbine blades of single crystal, turbine disks of powder metallurgy and deep chemical milling for a duct were developed to use for the long term engine test and the prospect to commercialization could be obtained. The following techniques have been established and the results satisfying target specifications could be achieved: the three dimensional aerodynamic design of compressor and turbine, the adoption of air blast fuel atomizer to suppress the smoke generation, an afterburner of spray bar system and the mounting type FADEC (full authority digital electronic control) to control the engine with the afterburner. 4 refs., 15 figs., 4 tabs.

    The noncontact measurement method of rotating blade vibrations was developed for fans, compressors and turbines, and applied to turbofan engines and industrial gas turbines. The method required no machining of blades and rotor except sensors attached to a casing to detect blade-tips. The method allowed to measure simultaneously the vibration of all blades, by measuring elapsed times of blade-tips rotating from a measuring start point to a detecting point, and detecting the time differences between a vibration and non-vibration condition. The measuring system was composed of the detectors and subsystems for signal processing, control, calculation and display. The vibration wave forms of a few blades and the maximum vibration amplitudes of all the blades were displayed on a realtime basis in an on-line monitoring mode, and an off-line data processing mode was also available for subsequent analyses and reviews. The results of application to existing engines favorably agreed with those of strain gage measurements. 16 refs., 75 figs., 3 tabs.

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

    This is the report No. 98 issued by the Inorganic Material Research Institute. An intelligent material is a substance and/or material which responds intelligently to environmental conditions and exhibits functions. One of the features of amorphous materials including amorphous glass is a large freedom in chemical composition. These materials maintain order in short distance, but have as a whole the turbulent and specific atom orientation. Therefore, high tolerability in selecting the composition, and diverse synthesizing methods are available. A wide range of utilization may be conceived, such as introduction of the state of electrons having different valences in a structure, and the diverse chemical combinations. Patterns of existence of polyhedrons having different orientations, and how they are connected correlate closely with an external environment. Intelligent materials have high freedom against change in the external environment and are suitable to exhibit intelligent functions. Setting heat and light as the external conditions, attempts have been made on search and creation of intelligent materials based on state change induced by interactions between the two factors. Fundamental studies have been made on synthesis of different environment responding glasses and films, and on factors and phenomena for exhibition of the intelligence. 62 refs., 91 figs., 8 tabs.

    Studies are conducted to promote energy-saving in construction works as part of environment protection programs. The first phase is for survey and analysis works for energy-saving in the current building design and construction works, and for processes, procedures and materials in model works (construction of sub-stations). The second phase is for studying energy-saving designs, materials and procedures, which are applied to model works, to assess their energy-saving effects , costs and applicability. The horizontally developed samples are prepared for the future development, based on the `continuous improvement of environment-management systems by establishing the PDCA cycles,` which is one of the basic requirements of the ISO14001 (environment management system). These efforts have reduced CO2 emissions associated with the manufacture of construction materials by 20%, mixed wastes by 45%, and plywood frame requirement by 70%.

    Discussed herein are mooring performance requirements of the new types of marine structures now proposed, and characteristic ranges and future expansion potential of the existing mooring systems. The mooring systems studied for floating structures are catenary, single point (multi-leg and single-leg types), fixed structure with fender and tension leg mooring systems. The studied items include extraction of the elements that constitute rigidity of the spring for horizontal mooring, survey on and data collection for each element, determination of element ranges, programs for mooring analysis, assessment of mooring characteristic ranges, and potential development of the characteristic ranges. It is concluded that the existing systems with their current characteristic ranges and future possibility are insufficient for the future marine structures. It is therefore necessary to develop new mooring concepts, instead of expanding the current concepts, in order to meet the mooring performance requirements for the new marine structures. 14 refs., 9 figs., 11 tabs.

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

    This paper proposes a non-powered heat transportation (HT) system. The system is composed of an evaporator, condenser, receiver, switching chamber (SC) and 3 check valves which are connected with each other by vapor and liquid tubes. Condensed liquid supercooled in the condenser exists in the receiver forming a saturated condition at a concerned temperature, and condensed liquid is lifted up from the condenser to the receiver by pressure difference between the evaporator and receiver. Generally evaporation pressure is higher by pressure difference between liquid levels in the condenser and receiver. The lifted up amount of condensed liquid increases with evaporation pressure, resulting in an increase in heating surface area of the condenser and amount of condensed liquid. A proper evaporator pressure is thus retained by reduction of evaporation pressure. SC is connected with the receiver and evaporator, and switches high- and low-pressure valves by motion of an inner float to transport heat from the evaporator to condenser. Reverse HT is possible as normal latent HT by installing a bypass. Some problems are also described. 2 refs., 8 figs.

    The effects of pitching and heaving motions of an aerofoil on accretion of ice thereon are investigated for the design of wind turbine blades. The conditions under which an aerofoil shows a heaving motion are 10m/s as wind velocity, -12degC as ambient temperature, 0.5Hz as frequency and 5mm as amplitude. Initial growth of ice is stochastic to a great extent; ice grows rapidly around the seed which is formed by chance somewhere on an laerofoil. The effects of ice appear in the flow field in the vicinity of the aerofoil front edge, as it continues to grow, providing different conditions for water droplets to collide with each other. Average ice shapes can be classified by environment, although at low repeatability. Range of ice accretion varies depending on aerofoil motion, whether it is pitching, heaving or at rest. The most important factor that determines behavior of ice accretion is conditions of the flow field near the aerofoil front edge. In a pitching or heaving motion, its speed is an important factor for growth of ice. 2 refs., 5 figs.

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

    This study is being progressed during a period from 1992 to 1999 as part of the NEDO`s clean coal technology program. This paper describes what has been discussed to date. The absorption method and the adsorption method may be used to recover CO2 as means to deal with the problem of global warming resulted from burning coals. These methods, however, have problems in economy caused from concentration of CO2 in flue gas being low. The present study is intended to raise the CO2 concentration in flue gas by using oxygen plus circulated flue gas in the place of combustion air, so that CO2 may be recovered as it is without being separated from the flue gas. Therefore, an oxygen-blown pulverized coal fired power generation plant having a cryogenic oxygen manufacturing equipment was designed to discuss the plant operability and economy, and the pulverized coal combustion technology by using a dynamic simulation. A large number of findings have been obtained already, and the study has reached a level at which grasping the whole image is now possible. 13 figs.

    Discussed herein are mooring performance requirements of the new types of marine structures now proposed, and characteristic ranges and future expansion potential of the existing mooring systems. The mooring systems studied for floating structures are catenary, single point (multi-leg and single-leg types), fixed structure with fender and tension leg mooring systems. The studied items include extraction of the elements that constitute rigidity of the spring for horizontal mooring, survey on and data collection for each element, determination of element ranges, programs for mooring analysis, assessment of mooring characteristic ranges, and potential development of the characteristic ranges. It is concluded that the existing systems with their current characteristic ranges and future possibility are insufficient for the future marine structures. It is therefore necessary to develop new mooring concepts, instead of expanding the current concepts, in order to meet the mooring performance requirements for the new marine structures. 14 refs., 9 figs., 11 tabs.

    In order to grasp the phenomena actually occurring in the combustion chamber for improving the combustion and for reducing the exhaust gas emission of the diesel engines, the visualization techniques are becoming to be essential and indispensable. The authors have observed the spray and combustion, when proceeding the combustion improvement by the high pressure injection, and then have performed the image processing and simulation calculation based on them. The high pressure injection devices used for the experiment are the intensifier type and accumulator type which can generate the injection pressure more than 200MPa, and both of them are the electronic controlled hydraulic drive type, and are driven separately from the engine. Since it was found that the analysis of high pressure injection by the hologram is limited in the conditions, as for the spray, the spray analysis was performed by the transmitted light attenuation method and laser sheet method. As for the combustion, the engine for observing the combustion was trially made, and then the combustion state was observed by the high speed photograph. Furthermore, the flame temperature analysis by the image processing using the combustion photograph and the analysis of flow and turbulence of the flame were carried out. 9 refs., 16 figs.

    This paper describes odor in automotive cabin. Odor of new cars is rapidly disappeared during the use. This is greatly due to the adaptation of olfaction. The generation of odor is also decreased. It was found that aliphatic and aromatic hydrocarbons were rapidly disappeared. Decrements of oxygen containing and sulfur compounds were low. For amines, high boiling amines increased after three months. The odor component from crews was derived from the exhalation. Trimethylamine, methyl sulfide as well as iso-prene were detected. They could be derived from tobacco smoke, perfume and hair conditioner. Exhaust gas of diesel vehicle going ahead is one of unpleasant odors from the running atmosphere. A correlation coefficient 0.77 was obtained between the stimulation and aldehyde/ketone. A correlation equation was deduced using stimulation, discomfort degree and odor characteristics as object variables and using logarithms of trace analysis values as explanation variables. There are still a lot of unknown issues concerning combined odors. 9 refs., 9 figs., 1 tab.

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

    The energy saving environment-friendly technology for low- grade difficult-to-process ores was researched focusing attention on the hydro-metallurgical process of non-ferrous metals. This research aims at development of both effective leaching system of metals, and separation/crystallization system recognizing the property difference between metal ions in solution. The leaching system allows the inexpensive molecular level control of electron transfer, mass transfer of metal ions and stabilization of leached metal ions in a solid/liquid interface. The system thus allows selective leaching of metals from various resources such as difficult- to-leach sulfide minerals to prepare concentrated solutions. The separation system can obtain high-purity solutions including each metal ion by advanced separation/concentration technology from the solutions. The crystallization technology (including electrolysis) is developed for preparing target metal materials by molecular level control of nucleation, particle growth, thin film formation and bulky metal formation processes. Overall energy consumption is reduced to 1/3 of that of the pyro-metallurgical method, aiming at zero emission. 15 refs., 14 figs., 11 tabs.

    Summarized herein are R and D results of the researches on the chemical heat storage systems, plant simulation techniques and combined systems, and international technical exchanges, for R and D of the super heat pump energy accumulation system. For the high temperature heat storage type (utilizing ammonia complexes), the initial research targets are almost attained, as a result of the designs of a chemical heat storage unit having heat storage capacity of 1,000 kWh. For the high temperature heat storage type (utilizing hydration reactions), a 25 Mcal-scale pilot partial test unit is operated, to study applicability of the practical materials and other operation-related themes. For the low temperature heat storage type (utilizing hydration reactions by solute mixing), a pilot system is operated, to attain heat recovery of 75% or more, heat storage density of 30 kcal/kg or more, and output temperature of 7 degrees C. For the low temperature heat storage type (utilizing clathrates), the evaluation tests by a pilot plant produce heat recovery of 93.2% and heat storage density of 32.0 kcal/kg.

    This paper reports the result obtained during fiscal 1994 on a demonstration research on photovoltaic power generating systems. Solar cells with an output of 750 kW, storage battery facilities with an output of 3,058 kWh, three DC-AC converters with a rating of 250 kW, and a diesel generator with an output of 300 kW having been installed up to the previous fiscal year were combined to perform comprehensive adjustments and tests such as battery charge/discharge tests and AC parallel operation tests. The battery charge/discharge tests revealed that the 10 hour rate discharge capacity meets the specifications, and the batteries are free of deterioration after a demonstration operation of about 4.5 months. Difference between the power generation record and the planned value is thought due to the following reasons: the array output data in a power line connected system come about 90% of the simulation result due to correction coefficient for the solar cell conversion efficiency; the inclined face insolation results in less by about 7% than the planned value, and the transmittable power amount less by about 14% in total; the load power amount is less by about 7% than the planned value; and the balance supplementing power factor increases by about 4%. 5 figs., 2 tabs.

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

    Disaster caused by liquefaction is an important problem for the development of water-front because most of the places suffered from liquefaction disasters recently are located on sandy grounds. The damaged cases in the past due to liquefaction induced by earthquakes are grouped into: subsidence and inclination caused by the loss of supporting force of the ground, coming to the surface of buried structures due to excess pore hydrostatic pressure, destruction of lifeline accompanying the fluidization of ground, breakdown of bulkhead, retaining wall, etc. by increased earth pressure, sinking of soil structures, ground fissure, sliding, and immersion in floods and submergence of farms due to spouting of underground water. As regards prediction of liquefaction, description is made on the prediction of the occurrence of liquefaction and liquefaction prediction for which sedimentation environment is taken into consideration. Open-cut investigation can be said as the most effective means for accurate learning of the depth, thickness and sedimentation structure of liquefied layers. Liquefaction layers found in remains are also introduced. 16 refs., 6 figs.

For the study of technology trends, international conferences held in UK, Germany, and Hawaii are introduced, and domestic meetings, i.e., Annual Polymer Congress and Polymer Conference, are summarized. In addition, Precision Polymerization Forum and International Workshop on Precision Polymerization were held. The basic studies include a quantum-chemical elucidation of the elementary process in polymerization reaction, time-resolved analysis of polymerization process and polymer properties, synthesis of polymers with controlled microstructures by coordination polymerization using metal complexes, synthesis of polymer with controlled microstructures by precision polycondensation, molecular recognition in catalyst-reaction site, and synthesis of imprinting polymers. 246 refs., 117 figs., 14 tabs.

    An investigational study was conducted of the brain function aiming at developing an interface with the same function as humans have. In the study, the most up-to-date information/knowledge and future problems were examined on brain measurement, brain modeling, making a model an element, and the brain function data processing system. As to the brain measurement, the paper took up the multielectrode simultaneous measuring method and the optical multipoint measuring method as an invasive measuring method, and the functional magnetic resonance imaging, near-infrared spectroscopy, magneto-encephalography, and electro-encephalography as a non-invasive measuring method. Relating to the brain modeling, studies were made on senses of sight and smell, the movement control and the learning. As to making a model an element, how to make the modeled function a chip on silicone for example becomes the problem. Reported were two reports on making the sense of sight an element and one report on making the parallel dispersed processing mechanism of brain an element. About the brain function data processing system, three reports were made on the present situation, matters in question, and the future development of the system in the case of catching data processing as a system taking a step ahead from making the model an element. 250 refs., 74 figs., 11 tabs.

    My efforts towards at the development of aeroengines since the end of the war are described. The J3-7 engine propelled the T1 trainer plane, and was installed as booster aboard the P2J antisubmarine patrol aircraft. It was the first jet engine that Japan produced after the end of the war, and had been in use until quite recently. I took part in the construction of a prototype of the JR100 series designed to serve as VTOL (vertical take-off and landing) aircraft lift engines, and in the test thereof. As the shift from turbojet to turbofan proceeded, I participated in the development of the FJR710 engine under the guidance of National Aerospace Laboratory, and the product was installed aboard an experimental STOL (short take-off and landing) aircraft Asuka. I next joined a Defense Agency initiative for a reheat turbofan to replace the J3 aboard trainer plane, and the result was the low bypass ratio/high output F3 engine. In 1989, Ministry of International Trade and Industry decided for a large-scale project of developing an engine for a next-generation supersonic transport, and the HYPR (Super/Hypersonic Transport Propulsion System) project was started. The project was participated in by manufacturers from overseas, which were GE, P and W, RR, and SNECMA. The foreign corporations worked on an equal footing with the Japanese parties, and collaboration between the participants was smooth, with each party endeavoring in the field they were good at. The project will be concluded as scheduled in fiscal 1998. (NEDO)

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

    The adsorption of acetaldehyde by porous ceramics impregnated with hydrazinium aluminum sulfate (HAS) is studied. Silicagel, activated alumina, activated clay, and activated carbon are compared, and it is found that silicagel and activated clay are suitable as a substrate for HAS impregnated adsorbent. The adsorption mechanism of acetaldehyde by the adsorbent is believed to be one in which acetaldehyde reacts with hydrazinium and yields acetaldazine. The adsorption capacity of the adsorbent at low acetaldehyde concentration of 0.1 ppm was as large as 1.36 mol/kg. This adsorption capacity at 0.1 ppm acetaldehyde concentration is remarkably larger than that of conventional activated carbon. Hydrazinium decomposes easily in the air because it is a strong reducing agent and reacts with oxygen or carbon dioxide. But hydrazinium impregnated on porous ceramics with HAS becomes more stable and maintains reactivity with acetaldehyde for longer than six months. An adsorbent made of porous ceramics impregnated with HAS is useful as a deodorant for acetaldehyde. 8 refs., 6 figs., 6 tabs.

    Summarized herein are R and D results of the super high performance heat pumps and elementary equipment, for R and D of the super heat pump energy accumulation system. For R and D of the super high performance compression heat pumps, the R and D efforts are directed to tests and evaluation of the pilot plant for the highly efficient type (for heating only), which produce the results of COP exceeding the target of 8; to tests of the anti-corrosion measures for the aluminum heat exchangers for the highly efficient type (for cooling and heating), by which the effective inhibitors are selected. The hybrid systems of the super high performance compression heat pumps and chemical heat storage are also studied in detail. The R and D efforts are directed to construction and operation of the hybrid heat pump system to collect underground heat for the high temperature type (utilizing low temperature heat source), which produce the results of confirming possibility of efficient heat collection for extended periods; and to improvement, construction on a trial basis and operation of the high-speed reciprocating compressors and steam superchargers for the high temperature type (utilizing high temperature heat source). For R and D of the elementary equipment, tests and evaluation are conducted for the EHD heat exchangers which use R123 as the new working fluid. (NEDO)

    Discussions were given on airbags equipped in passenger cars as to methods of evaluating their deployment injuries. Airbag deployment injuries occur in occupants being out of position. In a driver`s seat, an injury may occur when an air bag deploys under a condition that a driver with relatively short body height gets closer to a steering wheel to maintain the driving posture. In a front passenger seat, if a child is not held in a restraint equipment, the child may be blown off into the vicinity of the airbag, whose deployment can cause an injury. According to the result of a test performed on a driver being out of position, the test method using a hybrid 3 dummy specified in the present ISO procedure may not necessarily be said to produce an evaluation on the worst case. In order to solve the problem, an ATD dummy which can measure bend in each rib independently would be used, or the hybrid 3 dummy must be measured in the worst set position. 4 refs., 8 figs.

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

Important proficient techniques in manufacturing industries are becoming extinct because of insufficient succession to next generation. The proficient machine system was proposed to cope with such situation. This machine system includes the mechanism for progress and evolution of techniques and sensibilities to be adaptable to environmental changes by learning and recognizing various motions such as work and process. Consequently, the basic research fields are composed of thought, learning, perception and action. This machine requires not only deigned fixed functions but also introduction of the same proficient concept as human being to be adaptable to changes in situation, purpose, time and machine`s complexity.

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

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

    With an objective of establishing a practically usable process to manufacture substitution natural gas, discussions have been given on the technical, economical, and developmental problems therein. This paper summarizes the achievements in fiscal 1992. With respect to the possibility of applying the coal SNG to power generation fuel, a power generation system composed of coal SNG, pipeline transportation and natural gas was recognized of having the significance of technological development because of its capability of raising the power plant utilization rate and possibility of being superior in the economic aspect. In the study on enhancement of aqueous solution yield, performance of the ARCH-2 reactor was discussed by the simulation forecast using a mathematical model, whereas the benzene yield was found possible to be raised up to 15% in the carbon conversion rate. As the target of the hydrogasification process to be developed by Japan, based on the study results of the current fiscal year, three points consisted of SNG yield maximization, cooling gas efficiency maximization, and BTV yield maximization were indicated, and it was proposed that a process having flexibility in the product yield should be developed.

    Concerning the above, it is discussed whether such a system is feasible in Japan. A zinc/air cell system requires some special plants for zinc regeneration, etc. It is necessary to build a zinc refining plant and to install dozens of electrode replacing facilities in an area dozens of kilometers in diameter with the plant at the center. For such a system to be functional, there have to be several tens of thousands of automobile users in a limited area. In Japan, so large a number will not be found anywhere even if the appeal is directed to those in the postal service and electric utilities. There will be no economic success in Japan, different from in Germany. As for the economic comparison between a zinc/air cell system and natural gas system, the two will be equivalent to each other as far as the use of the quick filling stations for the natural gas automobiles remains as it is. When the number in consideration is so large as several tens of thousands, however, the natural gas system will turn out to be economically superior to the zinc/air cell system. 19 figs., 29 tabs.

This paper summarizes the achievements in fiscal 1991. The summary of surveys in the current fiscal year is as follows: the coal hydrogasification process is positioned as having high necessity in the gas industry because of its high thermal efficiency and low gas cost; in order to evaluate the reaction heat in the hydrogasification reaction, a mathematical model having flexibility was structured, whereas a large number of findings has been derived, including performance of the reactor and the optimum operating conditions; in addition to having made clear the conditions for an entrained bed hydrogasification reactor, comparisons and discussions were given on the internally circulating reactor and one-through reactor; studies were performed on thermal efficiency and gas cost in the optimized process configuration o the ARCH-1 process base; and a proposal was made on the test for a new reactor having the two-step reaction zone that could be expected of increased yield in aqueous solution, and could contribute to reducing the gas cost.

    To promote the introduction of methanol fuel into the thermal power plants, total assessment was provided. For calculating the methanol production cost, the plant was assumed to be constructed in the Southeast Asia or Middle East. Two methods, i.e., steam reforming and gaseous phase fluid methods, were investigated. Since the price of natural gas is low in the Middle East, the methanol production cost by the gaseous phase fluid method is estimated to be about 1.5 yen per thousand kcal. The transportation cost can be reduced into one-half to one-third of current cost using a large-scale tanker. Although the heating value of methanol per weight is lower than that of LNG, the volume flow of methanol is similar to that of LNG due to its low specific gravity. Conceptual designs were conducted for some power generation systems, such as gas turbine of combined cycle, diesel engine, and fuel cell. The power generation cost was estimated to be 8 to 9 yen per kWh, which depends on the receiving price of methanol. It is nearly equivalent to that of LNG combined cycle power generation. There are no problems of air pollution and ash disposal.

    Survey/study were conducted of potentiality of the cogeneration business using ligneous biomass in Kami County and the periphery of Kochi Prefecture. In the survey, the following were studied: regional characteristics of the said area, levels of technology of direct combustion/thermochemical conversion, future technical trends, system candidate, grasp/analysis of the resource amount, characteristics of ligneous biomass resource in the said area, analysis of economical efficiency of the procurement of biomass resource, grasp of energy users, etc. As a result, a system was selected of a 1,000kW scale cogeneration of ligneous resource. At the present technology level and under scale conditions, it was found out that the fixed bed direct combustion system was the most profitable in securing the economical realization. As to the system mostly for power generation, however, it was found out that the heat low in unit price of energy production should widely be used because the installation cost of plant is comparatively high. Facilities such as Kochi Medical Center where heat is in great demand throughout the year can expect profit from selling heat, and therefore, those have high potentiality of the commercialization.

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

What were learned from fiscal 1998 researches are mentioned below. The strength that the general-purpose fibers currently in use exhibit is so small as to be but several percent of what is theoretically predicted for them. Demand will increase a great deal if the actual strength is doubled, for which new technologies have to be developed including those involving super-fiber texture control. For providing the fiber with such functions as environment-friendliness, amenity, etc., it is necessary to develop phasal structure control technologies with regard to fiber morphology, surface texture, etc. For success in practical application in the future of such super-fiber materials, each specimen needs to be manufactured in the order of kilogram by way of trial. Moreover, fiber evaluation techniques have to be developed in the three domains of software, hardware, and interface. (NEDO)

    For the promotion of research exchanges on global environmental preservation with developing countries, Ms. Malee Santikunaporn, lecturer of Faculty of Engineering, Thammasat University, Bankok, Thailand was invited. Desulfurization/denitrification facilities, which are being widely spread in developed countries, have marked effects, but high prices are an obstacle to the spread in developing countries. To make them spread in developing countries, it is needed to develop the technology which is low in price and meets the actual state in developing countries. As a technology with high viability, a system to simultaneously remove SOx and NOx was cited in which Cu is used as catalyst and adsorbent and into which the catalyst regeneration process is integrated. Considering it, technical exchanges on Cu-SiO{sub 2} catalyst as the basic theme were made during September 26 - December 23, 1999. Through visits on and exchanges with Tokyo Institute of Technology, ICEET, University of Kyoto, etc., understanding was deepened about how each country is tackling environmental problems. The theme 'Oxidative sorption of SO2 by Cu-SiO{sub 2} catalyst: characteristics of catalyst' could deepen knowledge/information of the developmental research as a system for simultaneous removal of SOx/NOx. The data obtained indicated great practicality of Cu-SiO{sub 2}. (NEDO)

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

Described herein are the FY 1996 results. For creation of living soft tissues, N-ePTFE and Gf are found to be good base materials for cell growth in the serum-free culture, and may be applicable to bio-reactors. Sugar-bound high-molecular-weight compounds and artificial hyaloid body are created. For hard tissue materials, e.g., artificial articulation, the macrophage is activated by englobing worn debris of polyethylene, to activate the broken bone cells that absorb the bone, causing the artificial articulation to become loose. For researches on molecular motor mechanisms, it is considered that myosin changes the head morphology to give a driving force to the muscle, and this concept is studied in detail. The photosynthesizing protein is a molecule related to light and electricity, and is useful as the material to apply the living functions to industrial technologies.

    This paper describes achievements in fiscal 1979 in research on aqueous alkaline solution electrolyte fuel cells. Trial fabrication and tests for an oxygen electrode were performed on a catalytic electrode added with silver using carbonblack and graphites as carriers having excellent corrosion resistance and large surface area. Characteristics not inferior to electrodes using activated carbon as a carrier were obtained in both of the initial characteristics and continuous discharge characteristics. A platinum added electrode also showed the same performance as the silver added electrode. A hydrogen electrode containing Zr and iron among those containing Raney-Ni was found to have high oxidation resistance and stability in terms of life. A platinum added electrode using graphite as a carrier provided satisfactory initial characteristics as a hydrogen electrode. Research on a single cell construction has used and tested eight-cell laminated cells with an area of 1,000 cm{sup 2} using bipolar sheets made of carbon. The test verified appropriate the removal of produced water and heat using mainly the hydrogen circulation, which has been discussed in the summary design.

    To further enhance energy efficiency by improving on the gas turbine system, it is necessary, first of all, to develop superhigh-temperature materials to allow the system to operate at higher temperatures. Described in this report are studies on the application of MGC (melt-growth composite) materials which retain strength and plastic deformation capability even at high temperatures. Various compositions are explored for improvement on fracture toughness and thermal shock resistance. The Al{sub 2}O{sub 3}/YAG system is investigated for the study of relations between microstructural control and fracture toughness. Literature on the development of nanocomposites is surveyed, and a preliminary experiment is discussed for improvement on purity by zone melting crystallization. In a study for an advanced manufacture of larger crystals, technologies of crystal growth condition setting and optimization, quality stabilization, productivity improvement, and crystal size enlargement are taken up. Casting and machining technologies are studied to enable crystals to assume complicated shapes. For the purpose of elucidating the mechanism of the occurrence of properties proper to high temperatures, a study is made on the evaluation of mechanical and physical properties and on the mechanism and control of crystal growth.

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

    This report covers part of the efforts to develop new hydrogen production technologies. Out of many processes involving Cu-halogen and alkali carbonate-iodine systems proposed as novel thermochemical processes, after they are compared with each other, a process of a sodium carbonate-iodine system with nickel in between is chosen. The chosen process is deemed to be the most excellent among the processes disclosed up to fiscal 1975. A feasibility study is conducted for the chosen process from the viewpoint of reaction rate, separation of reactive substances from each other, method for reaction manipulation, materials for device constitution, and thermal efficiency. As for the measurement of reaction rate for each unit reaction, basic reaction data are determined centering about the nickel iodide decomposition reaction and the sodium iodide carbonation reaction, and then reaction conditions which are roughly satisfying are obtained. A larger reaction unit is built in which the amounts of substances that come into reaction are approximately 10 times larger than those in the ones used in basic experiments. The progress of reactions is observed in the reaction unit, with the size enlarged in preparation for future construction of still larger reaction units. Methods for selectively isolating hydrogen out of gases ensuing from the decomposition are evaluated from the viewpoint of energy efficiency. In the selection of a reaction manipulation method, a single unit reaction process is advocated, and its thermal efficiency is estimated. (NEDO)

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

    This report summarizes the fiscal 1974 research result on the solar heat power generation system with a tower light collection system. This system receives solar radiation energy by reflector group, and concentrates solar energy reflected by each reflector on the heat absorber mounted on the top of the tower. A ratio of the whole reflector group area to the receiving area of the heat absorber is called a concentration factor. The heat absorber converts concentrated dense radiation energy to thermal energy, and transfers heated thermal medium to the bottom of the tower to supply solar heat to a thermal plant after appropriate treatment. Based on the above basic idea, study was made on the total system and each subsystem, and some problems on component equipment and materials were extracted. After solving these problems and improving the whole system accuracy, these results are put to practical use for design and operation of an actual pilot plant.

    A proposal was given on a new processing process to use Ni-group super alloy, and elucidation was given on super plasticity phenomenon by using non-destructive tests. The Ni-group super heat-resistant alloy Mod. IN-100 subjected to different preforms by means of extrusion was given a super plasticity test at 1,050 degrees C to derive total elongation and 'm' value. As a result, it was disclosed that a material annealed for one hour at 1,070 degrees C after extrusion of 70% at 1,100 degrees C possesses the maximum 'm' value in the vicinity of 2.0 times 10{sup -2}s{sup -1}. The largest key to the new processing method is to improve the nature of the material, in which the plasticity manifestation velocity is accelerated by ten times to the order of 10{sup -2}s{sup -1} as described above. In addition, forging of IN-100 was made possible by using the ordinary forging equipment with the use of two-fold measures. The measures consist of maintaining temperature of IN-100 during casting by heating the die material to about 600 degrees C, rather than keeping it at a constant temperature, and then packing IN-100 in S35C steel material to accommodate the temperature decrease during casting inside the S35C pack. Thus, a processing method was made practical, eliminating need of the forging process to compress and solidify powder itself, that is the extrusion process. (NEDO)

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

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

    This paper describes the result of discussions on hydrogen fueled automobiles in fiscal 1978. Hydrogen fueled automobiles have a difficulty in developing methods for transporting hydrogen, whereas the liquefied hydrogen method and the metal hydride method are being studied in parallel at the present. It is also necessary to solve such basic problems as the method for supplying hydrogen to engines, the injection method, and countermeasures for abnormal combustion. Safety assurance is also important. Very little information is available presently on methods for storing hydrogen inside a car and supplying thereof, which are required for evaluating utilization of liquefied hydrogen to automobiles. Demonstrative surveys and researches are required to acquire basic materials for hydrogen feeding methods in broader meaning including storage and control. Therefore, fiscal 1977 has begun trial fabrication of experimental liquefied hydrogen tanks, and preliminary and experimental researches on types and materials for feed pumps. Fiscal 1978 has moved forward improvements in prototype tank performance (heat insulation method to reduce evaporation loss), trial fabrication of liquid level meters, trial fabrication of feed pumps (especially selection of materials for the sliding parts), and researches on flow rate control methods. Drawings for modification and experiment of the liquefied hydrogen tanks were prepared, and the promising candidates were selected for material combination in pump sliding parts. Durability tests are continuing thereon. Flow rate control was also discussed. (NEDO)

    The permanent magnets have been investigated and developed, for eventual commercialization of a 10 MWh power storage system by high-temperature superconducting flywheel. The permanent magnet rotors have been already developed in the previous years using a praseodymium-based magnet (Pr magnet) and neodymium-based sintered magnet (Nd sintered magnet), and the target rotational speed of 30,000 rpm has been attained. For development of the magnetic circuit to produce a stronger and smoother magnetic field, magnetic flux density of the Nd sintered magnet is measured. It shows a lower magnetic flux irregularity than the Pd magnet, but there is still room for further improvement. For development of large-size permanent magnet fabrication techniques, it is confirmed that the large-size Nd sintered magnet can be easily magnetized by partial magnetizing, as is the case with the Pr magnet. In this year, the irregular magnetic flux is three-dimensionally simulated, based on the results obtained in the previous years, to find that the simulated results are in good agreement with the observed ones. The measures to solve the problems are also investigated. It is also confirmed that the large-size ring magnet can be easily magnetized by partial magnetization. (NEDO)

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

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

On junction formation, the solar cell fabricated by spray coating showed output characteristics equivalent to that by rotary coating or phase diffusion, and inexpensive coating liquid, 1/40 of commercially available liquid in price, showed a sufficient result, however, the conversion efficiency of P{sup +}/N elements was insufficient. Schottky barrier polycrystal Si thin film was suitable for large-area elements without any property degradation. Small grain boundary density of polycrystal layers was also necessary. Temperature characteristics of collector element structure with a comb electrode were calculated theoretically. Change in diffusion length of minority carriers due to temperature well agreed between measured and calculated ones. Optimization calculation was also carried out. The size, curve, weight and transmissivity of plastic and glass materials for solar cell packaging were evaluated by continuous outdoor exposure tests. Fluorinated ethylene-propylene, methyl methacrylate and polycarbonate plates and glass were the most promising materials because of less deformation. (NEDO)

    Trends of research on carbon based composite materials were surveyed through studying various reports and technical literature and evaluation of the project named above was conducted through holding interviews with researchers. In the survey of research trends for which technical literature perusal was the main tool, it was found that in most technical articles the important task was the enhancement of oxidation resistance, that SiC coating was in use for this purpose, that the technology would meet its limit at 1,600-1,700 degrees C, and that it would turn useless at temperatures beyond 1,800 degrees C. For the evaluation of the project, interviews were held with nine researchers not taking part in the project. The researchers favored the project as far as the popularity of the project and the main implementing body and system were concerned, but they negatively evaluated the project's goal of using such materials at 2,000 degrees C in the atmosphere. This research report comprises four chapters which cover (1) trends of research on C/C (carbon/carbon) composites, (2) a summarized research report on C/C composites, (3) survey of patents associated with C/C composites, and (4) opinions expressed toward the project and the results of evaluation conducted on the same.

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

    Researches are conducted for the development of a technology of producing useful gases such as acetylene, hydrogen, carbon monoxide, etc., from coal by the use of the high temperature and high-density energy of the plasma jet. In an experiment using a 100kW 3-port plasma-aided gasification unit, rapid quenching tests are conducted using hydrogen and helium, where the reaction furnace is changed, the specimen feed device is changed, and the plasma torch head is replaced by a high-power head. In a test of the coal specimen, it is found that rapid quenching exerts a great effect on the prevention of re-decomposition of the generated acetylene into hydrogen and carbon black and that a rise in the hydrogen partial pressure results in a great decrease in the quantity of acetylene generated. The said torch head replacement increases the rate of the coal specimen infiltrating into the plasma flame, which brings about an increase in the quantity of acetylene generated. It is found after all that the conventional acetylene yield of 34g/kWh increases to 59g/kWh in a rapid quenching test in which the specimen is dried Akabira coal and the plasma is an argon gas plasma containing 40% hydrogen.

The conditions of optimum utilization of the system are studied for eventual commercialization and spread of these systems, including analysis of load types for specific purposes, prediction of operation management, economics of CGT, environmental impacts, and possibility of diversification of the fuel. The CGT cost analysis results indicate that a CGT system is well viable when the incremental initial cost of the power generator is kept below 70,000 yen/kW over the conventional system. The system can be doubled in scale at the largest. It can be further scaled up, when hybrid members with metallic materials are used. CGT is a basic technique for (system energy). In other words, the 21st. century will be the age of (system energy), i.e., (gas turbine). (NEDO)

    This report summarizes the fiscal 1974 research result on R and D of new type solar cells, which includes researches on (1) solar cell structure, (2) packaging, and (3) improvement of a conversion efficiency. In the 1st research, theoretical study was made on the relation between a solar cell efficiency and various design factors to obtain basic data for ordinary cell structure and vertical junction type cell structure. As impurity source, a thermal diffusion method using doped oxide by CVD was compared with that using boron nitride, resulting in no difference in solar cell characteristics between both methods. The measurement results on contact resistances of Al, Fe and Ni with electrodes prepared by electron beam deposition showed that these materials are applicable to Si more than 10{sup 18}/cm{sup 3} in impurity density as electrode materials. In the 2nd research, exposure tests were made on some kinds of specimens, resulting in no troubles. Study was made on production costs and structures suitable for automatic production of 4 kinds of packages with different basic structures. In the 3rd research, the prototype solar cell was prepared to use under solar radiation within 20SUNS. (NEDO)

The excavator system was designed to work at the target water depth of 200 to 250 m and excavation depth of 8,000 to 9,000 m, though not quite satisfactorily. There were several practical problems to be solved, e.g., those found in accuracy of reentry in the excavated section, cables connecting the driving equipment to the excavated section, and entangled hoses. The works were divided and system was configured in an attempt to secure all-weather type serviceability and to improve economic viability. The other major works included attempts to improve equipment functions and reduce manpower cost. Nevertheless, however, the construction cost was considered to be higher than expected, and no firm prospect was obtained whether the new excavator system was economically competitive with the conventional rig. The factors that pushed up the construction cost were various facilities needed by the new system with the separated excavation and driving sections, e.g., those facilities for helping the system land on the sea bottoms, material supply/storage facilities, and automated/unmanned facilities. The system failure and other items related to reliability are no clearly understood, making it difficult to compare it with the conventional rig in service factor. It was not adequate, therefore, to advance the next R and D phase as planned, and decided that the project was suspended to see the world development trends, because the clear plans for the future could not be drawn at that time.

    Element technology research was performed on 'rotation control' aimed at practical application of a 10-MW class high-temperature superconducting flywheel power storage system. As part of the research, researches were carried out on small-size and middle-size models, low-loss control type magnetic bearing, and large-size models. For the small-size model, as a result of performing performance tests on the protective bearing by using a testing machine, it was revealed that the model is free of problems in the test for up to 5000 rpm. For the middle-size model, fabrication and installation were completed on a middle-size rotation control testing equipment having CFRP-made flywheel with a diameter of 1 m. In the control type bearing, as a result of adopting a homo-polar type magnetic pole, the rotation loss was reduced to about 1/5 of that of a hetero-polar type. The amount is about 75 W (12000 rpm) when the bias current is 1.5 A. Concept design was implemented on a 2-MWh flywheel bearing system supported with a high-temperature superconducting magnetic bearing as a full-size flywheel. The CFRP-made flywheel has a diameter of 4 m, and a circumferential velocity of 1200 m. (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, 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.

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

    The mind-based technology (MBT) was investigated to be developed, for materializing the world where the human race and machinery live together without sense of incompatibility. Based on the human mind, the MBT is a technology to support the personal expression which respects the value judgment, diversity and individuality in the human life. For it, it is important to technologically comprehend the human mind and physiological/psychological state, and particularly, control the human will. In order to structure the social system in which the human race and technology live together, it is also important to build a life system information processing model which simulates the formation process to integrate the feeling, knowledge and conscience, together with an action system to be established. As an image to which the MBT is applied, support will be extended to the life fulfillment, personal expression and hearty communication. Development is expected toward the social security technology with robots living in the human society. Pursuing the mental richness and worthwhile life, the high-grade mature society needs the technology to communicate with the machinery gentle to the human race on the mutual interface. 21 refs., 8 figs.

    Out of the developments of high efficient boilers which have been continued since fiscal 1993, the paper reported the result of the development conducted in fiscal 1996. The oxygen combustion (the oxygen enrichment combustion including 100% oxygen combustion) decreases the amount of flue gas and reduces heat loss of the flue gas, and is also effective as NOx reduction measures. The experiment was conducted using testing furnace. The boiler efficiency rapidly increased with the increasing concentration of oxygen enrichment. In the pure oxygen combustion, the overall boiler efficiency of a 106% level (low heating value standard) is expected. Since the boiler wet flue gas is decreased, the NOx emission is reduced. The boiler can raise the combustion temperature with no fear of NOx and can be reduced in size. CO2 decreases in proportion to the energy saving effect. The development of a condensation flue gas heat exchanger is aimed at recovering heat down to the low temperature. Prediction of heat transfer in the steam condensation region becomes possible, and the size reduction can be expected. Dew point corrosion resistant materials were also selected. As to the high speed combustion control, a simple type using micro-processor was developed. Obtained were high speed, compactness, electric power saving, and high controllability. 14 refs., 306 figs., 88 tabs.

The utilization field of CGT may include cogeneration and portable power generator, but putting it into practical use requires that it be superior in environment protection performance such as gas exhaust, noise and vibration, economic performance, safety, and adaptability with the utilization fields. From such a viewpoint, discussions were given on its adaptability with the society based on different characteristics of the CGT, and other conditions such as related laws and regulations. The first edition investigated the developmental trends in ceramic materials, and the second edition studied the CGT utilizing systems, in particular, the status of utilization and proliferation of the current cogeneration systems. The edition evaluated various conditions required for conceptual design of the system. The third edition put into order the environmental regulations and future trends in order to identify the effect of introducing the CGT. (NEDO)

    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.

    Abrupt and steep climate changes of the millennial scale as represented by the Dansgaard-Oeschger cycle (D-O cycle) and the behavior of the global surface layer system in their wake are outlined. The D-DO cycle is the abrupt and steep climate changes that are recorded in the Greenland continental ice sheet, and is grasped most typically as changes in the oxygen isotopic ratio in the ice. Studies reveal that the D-O cycle is a global episode that accompanied interaction between various subsystems constituting the global surface layer system. It is believed that in the D-O cycle there were changes not only in temperature but also in aridity/moisture and in the sea level, and probabilities are high that there was a great local variation in the way the changes took effect. The possibility has now become lower that the D-O cycle occurred in the interglacial epoch in the high latitude belt in the northern hemisphere, yet it remains likely that the climate changes driving the D-O cycle continued in the low latitude belt. 57 refs., 8 figs.

    Efforts were exerted to achieve efficient expression of proteins of hyperthermophilic bacteria, hyperthermophilic archaeabacteria in particular, using a heterogene expression system in which Escherichia coli was the host. In an effort to search for genes related to protein folding and to elucidate the mechanism of folding, chaperonin and prefoldin subunit genes, out of various factors participating in protein folding in hyperthermophilic archaeabacteria, were cloned, and expressed in Escherichia coli. As a system for analyzing protein folding reaction, an experimental system was established on a substrate comprising isopropyl malate dehydrogenase, citrate synthase, glucose dehydrogenase, and a green fluorescent protein. Studies were further conducted to elucidate the mechanism of expression of enzyme genes in Escherichia coli for the establishment of a mass production method for useful enzymes. Also carried out was the research and development of an element technology evaluation system involving protein expression. (NEDO)

    The previous report explained that an excellent spherical particulate pigment with a grain size of 0.5 mm or less can be obtained by preparing multinuclear aluminum lakes from acidic dyes and multinuclear aluminum salt using water droplets in a W/O emulsion as reaction fields. This paper describes preparing pigments varying the charging concentrations of the pigments in a W/O emulsion and the droplet particle size to discuss the mechanism of forming the pigments. As a result, it was found that the particle sizes in the produced pigments have a clear correlation with the charging concentrations of the pigments and the droplet particle sizes in the W/O emulsion. A pigment produced in the W/O emulsion forms only in its own droplets, and reflects its particle sizes. Films dispersed with pigments having different particle sizes were prepared to discuss their tinting abilities, whereas it was clarified that the smaller the particle size, the higher the tinting ability and the higher saturation in colored paint films. 6 refs., 9 figs., 3 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.

    A study is made for the elucidation of the effect of microgravity on biofunctions. The protoplast of shiitake is exposed to microgravity and then cultured, and a significant difference occurs. The rate of colony formation by cell fusion in the test sector is found to be two times higher than that in the control sector. When swimming ciliates which are unicellular are suddenly exposed to microgravity, their swimming speeds changed differently according to the direction of swimming. When a mouse subjected to acupuncture for three days is exposed to microgravity, its water metabolism and excretory function are enhanced. A mouse treated with Chinese medicine reacts in the similar way. The change due to microgravity in the amount of acetylcholine in the hypothalamus is found characteristically time dependent. Mice infected with lethal herpes viruses just after exposure to microgravity die at a rate in proportion to the number of exposures and to the amount of viruses given. The migration speed of chemical stripes in case of a gel-base BZ (Belousov-Zhabotinsky) reaction under microgravity is equal to that on the ground. The trigger wave migration speed in case of a water solution-base BZ reaction under microgravity is reduced to approximately 80% of the speed on the ground. 12 refs., 31 figs., 3 tabs.

    For further improvement of iron system materials, supermetals with ultimate characteristics were researched. Since their strength and toughness have been improved with grain refinement by thermomechanical treatment, improvement of single-phase steel is nearly completed, and the study on ultra-fine multi-phase steel is indispensable. Bulky materials are also restrained from grain refinement because of the capability of existing processing facilities. Making a breakthrough in such restraint requires a challenge to high-speed rolling, repeated shear deformation and ultra-high strain rate process beyond conventional technologies. Further improvement of microstructure and dynamic characteristics requires other energies such as magnetism as well as mechanical energy. {gamma}-{alpha} phase transition important for structure control of steel materials is dependent on magnetism. The study on structure control and characteristics improvement under ferromagnetic field is essential in the future. Material improvement such as reduction of impurities and circulating elements, environmental measures, and mechanical alloying remain as issues to be studied. 224 refs., 176 figs., 18 tabs.

    For the development of an airborne electromagnetic prospecting method capable of deeper exploration, a basic study was made about a system wherein a transmitter (source) is positioned on the ground and the receiving is done in the sky. Even in case of this airborne electromagnetic method, the TDEM method is supposedly advantageous over others as in case of groundborne exploration. In the study, the transient response of an airborne vertical magnetic field to a horizontal layered structure was calculated. The current source was 2000m long with a capacity of 30A. The one-layer structure was a 10 Ohm m semi-infinite ground, and the two-layer structure had a 100 Ohm m structure just under the one-layer structure. The result of the calculation suggests that, in the absence of a layer of extremely low resistivity, observation of an approximately 1 second long transient response aboard a helicopter flying at approximately 50km/h will enable an approximately 1000m deep exploration. Problems to affect airborne observation, such as swinging, natural magnetic field fluctuation, and artificially produced noises were investigated by use of a magnetometer suspended from a helicopter in flight. 2 refs., 6 figs.

The equipment consists of a chiller unit with 5 HP, a motive power board of three-phase 200 V/feeder with an annual power capacity of 20 kW at maximum, and a micro-computer to control the culture environmental conditions. Discussions were given on the equipment performance, profitability, production capacity for salads and lettuces, and related data. Although the system has some disadvantage in the economy, it provided effective results on the know-hows in culturing high-class vegetables and fruits under season-free and chemical-free conditions. Since the natural light is also required, the professional knowledges and know-hows in this area were incorporated in the development. Fluorescent lamps emitting three primary colors of red, green and blue were devised and used. Because insufficient light intensity would raise the temperature only up to 42{degree}C when the ambient temperature is 25{degree}C, a proximity illumination system was adopted, which provided 45KIx high light intensity as well as the working spectra over an wide area. Tomato cultivation has also become possible, which is an epoch-making success. The system yielded better than hydroponic cultivation in solar greenhouse of the same size. 11 refs., 16 figs., 2 tabs.

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

    Fracture behavior of Al2O3-TiO2 sprayed ceramic coating was investigated at low cutting speeds when using two dimensional cutting. Scanning electron microscope was used to observe the generation, development and propagation of cracks during cutting. Small cracks and fracture have been developed in the cutting groove along the cutting direction, and there has been many fractures in spray particles unit. In the initial stage of cutting, radiant cracks have developed on the sprayed coating, however, linear big cracks starting from the cutting edge towards the cutting direction, have developed. The cracks have developed along the grain boundary of coating component, and cracks progressed along the portion with weak bonding force. When the depth of the cut was under 5[mu]m, the cutting face has formed many microfractures, and the cutting has been very stable. It has been necessary to select the cutting conditions that do not cause big fracture, microcutting and so on, in order to achieve favorable surface condition with minor fractures. 8 refs., 13 figs., 2 tabs.

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

    It is intended to recover more effectively thermal energy currently discharged from marine vessels into air. This paper describes a diesel engine combined power generation system in which medium-order waste heat energy from a diesel engine for power generation in a marine vessel is recovered and utilized to operate a Rankine cycle system (using the waste gas as the high temperature source and sea water as the low temperature source), thus the thermal energy is recovered as a motive force. Two kinds of fluorocarbons and steam were discussed as a working fluid. Due to fluorocarbons making the whole system ultra-high in pressure, and from a viewpoint of high-temperature thermal stability, the temperature was remained at levels from 100 to 200 degC, and a single-stage expansion cycle was used. With the use of steam, a two-stage reheating cycle was employed, by which the temperature is raised fully up to 300 degC and effective head of fluid was taken largely. Ceramic paint was used as a means to prevent sulfur oxide corrosion when the system is used down to the dew point, and its effectiveness was verified. Motive force recovered by combining the steam two-stage reheating cycle and the ceramic painted heat collector was calculated, whereas electric power output of about 45 kW was obtained from a main generator with 450 PS. The derived thermal efficiency was about 26%. 2 refs., 24 figs., 2 tabs.

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

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

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

    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)

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

    Mixed-compression type axisymmetric air intakes for ATREX engine have been tested in the supersonic wind tunnel from Mach 0.5 to 4 since 1993. The throat area of the intake can be variable with a translating center spike to accomplish starting and off-design operation since the ATREX intake must work well over the wide flight Mach number up to 6. Here are presented effects of the intake design Mach number, the air bleed from a center spike and/or a cowl around the throat, an angle of attack and blunt nose of the spike on the intake performance characteristics, that is total pressure recovery and mass capture ratio. It is found that bleeding from the center spike and the cowl influences mainly on total pressure recovery and mass capture ratio respectively. The advantage of rounding properly off the spike nose is confirmed. Small center spike cone angle and/or blunt nose is sensitive to the angle of attack. (author)

    For the turbine which is one of the principal elements of aircraft engine, progress in turbine use material development and cooling performance further heightened for the turbine are needed to grapple with the required heightening of turbine inlet temperature. In the present paper based on the turbine inlet temperature designed to be 1600[degree]C as a target, a two-dimensional model used for the turbine cooling performance test was structurally given together with the result of the above test which aimed at confirming the design calculation. As a result of cooling design for the turbine which was about 1600[degree]C in inlet temperature, the highest gas temperature was 1890 and 1470[degree]C on the stator blade and rotor blade, respectively. Both those blades were 0.66 and 0.62, respectively in cooling efficiency. To test the cooling performance, a two-dimensional cascade was tested with a doubly amplified model of cooling blade, the use of which could set its Reynolds number near that of the actual one. As compared with the actual operation, the test was made at low temperatures of 400 to 500[degree]C and low pressures of 0.02 to 0.03MPa. The test agreed with the design calculation in result. 4 refs., 8 figs.

    With an objective to achieve higher efficiency, higher density, and higher stability in power systems, research and development has been performed on superconductor power generators. This paper summarizes the achievements thereof in fiscal 1999. A verification test was given on the rotor of an ultra high speed responding generator. In a sudden short circuit test using the different phase charging method, no anomalies were found such as quench generation and vibration changes, wherein the healthiness of the generator was verified. In the VVVF actuation test, knowledge was acquired on the actuation method when the ultra high speed responding generator is applied to a combined cycle plant. After the verification test has been completed, the disassembly inspections such as visual check and non-destructive test were performed. With regard to the vacuum leakage found in the rotor under very low temperatures, the causes were presumed and the countermeasures were discussed by observing the weld structures. In the design research, the conception design on the 200-MW pilot generator was reviewed by reflecting the results of the verification tests on the model generator. At the same time, trial design was made on a 600-MW target generator. In summarizing the overall research achievements, the achievements and evaluations were summarized on technological issues that have been allotted to each research member. (NEDO)

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

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

    This paper proposes a cone type electro-hydrodynamical (EHD) heat collector, describes its structure and principle, and mentions possibility of improving the heat collecting efficiency. The paper proposes a heat collector with a shape close to a cone. Trees are of cone form so that their every leaf, branch and truck can capture solar energy efficiently. Imitating this fact existing in the natural world, a cone-shaped heat collector was fabricated on a trial basis to discuss its heat collecting efficiency. Furthermore, black round stones are placed in the inner cone of the cone- shaped heat collector of double-glass structure. A low boiling point medium is placed between the inner and outer cones to cause corona discharge in vapor generated by absorbing the solar heat, and generate corona wind for an attempt to accelerate heat transfer into a heat exchanger. Thus, development was made on a cone-shaped high-efficiency heat collector utilizing electro-hydrodynamical (EHD) effect, and elucidation was given on dynamic phenomena of an electro-thermal fluid. Heat transfer in the EHD heat collector has a possibility of being accelerated by generation of ionic wind. In addition, it is thought that there would be an optimum value in applied voltage to increase electric charge supply as a result of corona discharge. 1 ref., 2 figs.

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

    Discussions have been given on developing a seawater desalination system by solar energy distillation. The system is composed of evaporators installed on the seawater level, condensers placed on high and cool locations, and steam transport pipes to connect these two pieces of equipment. Steam is generated from seawater heated by solar heat in evaporators, and the steam is transported driven by low power consuming fans to higher locations through the steam transport pipes, where it is condensed by cool air in the condensers, and recovered as plain water. The concept is such that electric power required to operate the fans is supplied from photovoltaic panels, and all other energy is obtained from the sun. First, an experiment was performed upon noticing on methods of transporting and condensing the steam. The experiment used plain water rather than seawater. The heat source and evaporators were installed on the first floor, and the steam transporting fans on the second floor of an atrium. The thermal load was set to 1.5 times greater than average outdoor insolation amount. Increase in the distilled water recovery rate and distillation efficiency was verified by using the fans. The evaporation efficiency was found to tend to increase when the steam flow rate is increased. 3 refs., 10 figs.

    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)

    In order to find the higher critical strength, toughness and corrosion resistance of Al system materials than those obtained by conventional methods, crystal grain control was studied in a finer-grain region. The above characteristics of Al materials obtained by conventional technologies such as alloy element addition and heat treatment controlling crystal grains of several tens {mu}m are approaching critical values, resulting in poor characteristics for the latest needs. It has been confirmed experimentally in fundamental studies using small specimens that fine crystal grains of several {mu}m can remarkably enhance the above characteristics. Technology for creating mesoscopic structure-controlled materials was thus studied. In particular, creation of ultra-fine advanced Al alloy bulk materials by cryogenic processing method was selectively studied. The developmental approach and its issue were thus revealed for creating mesoscopic crystal structure by recovery and recrystallization of a highly distorted state obtained by cryogenic processing. 102 refs., 80 figs., 8 tabs.

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

    With an objective to develop an airborne electromagnetic survey method for greater depths achievable of exploration, a discussion was given on an exploration method of a type in which a transmitting device is placed on the ground to receive signals in an atmosphere. A prototype exploration apparatus is mounted with a fluxgate magnetometer, an attitude meter, a GPS, and a battery. This exploration apparatus is suspended on a 30 meter long rope from a helicopter to perform the exploration. Two flight tests on this apparatus were carried out in the Unzen area, Nagasaki Prefecture and the Motomiya area, Wakayama Prefecture. The ground source was extended to a distance of 1.5 km, and a current of about 20 A was flown with a quiescent wave having four-second cycles. The helicopter flew nearly horizontally at a ground speed of about 50 km, a flight altitude of 450 m above sea level, and a terrain clearances of 100 to 400 m. The obtained data had variations in correspondence with changes in roll and pitch angles, whereas the variation of about 5000 nT was reduced to about 1000 nT as a result of correction. It was not possible, however, to correct completely the variation with short cycles, requiring further discussions on frequency characteristics of the magnetometer. 6 figs., 1 tab.

    With respect to concept of resolution in seismic exploration using the reflection method, detailed considerations were given on processes of forming the resolution as a result of arranging observation points at vibration transmitting and receiving points. In the discussion, numerical experiments were carried out, in which the scattering stacking process is applied in a model having one scatterer existing in homogeneous media. The experiments investigated an imaging formation process of the scatterer when arrangement of the vibration transmitting and receiving points were changed from a coarse condition to a dense condition while the number of transmitting and receiving points is being increased. Resolution is created if waveforms having finite frequencies are used as input, and the imaging is performed by utilizing the limited number of vibration receiving and transmitting points. If the concept of equi-travel plane is used under these conditions, the equi-travel planes perform negation with each other, and it was indicated that visual resolution is expressed by how good the negating effect is. It was discovered that such concept of the resolution is quite ambiguous in terms of engineerings. 2 refs., 17 figs.

    In order to clarify the thermal decomposition behavior of nitrobenzene derivatives, the influences of interaction between nitro group and other substituents on thermal decomposition of nitrobenzene derivatives have been studied using sealed cell DSC and PM3 MO calculations. As a result, the mixtures of nitrobenzene and mono substituted benzenes having substituents containing hydrogen such as {sup -}CH{sub 3}, {sup -}COOH, {sup -}NH{sub 2}, and {sup -}OH showed 30-100 degree C lower T{sub DSC} value than nitrobenzene. Mono-substituted nitrobenzene having substituents containing hydrogen also showed lower T{sub DSC} value. On the other hand, PM3 MO calculations of hydrogen-bonded complexes of nitrobenzene and mono substituted benzene show that the hydrogen bonding of a nitro group and hydrogen of substituents may make the N-O bond length longer to induce the thermal decomposition. From These results, it can be said that the thermal decomposition of nitrobenzene derivatives would be unstabilized by the hydrogen bonding of a nitro group and a substituent containing hydrogen.

    To be ready for the computing-everywhere age to come, it is necessary to create environments in which the barrier-free utilization is ensured of various apparatuses of the daily routine, such as various bodily function substituting apparatuses capable of compensating for the degraded functions of disabled or aged individuals. Under the circumstances, a system for building man-machine interfaces in the home or the like is required, and fundamental technologies of architecture and information infrastructure have to be established on which the development of technologies for the field involved will proceed. Concerning the technologies already in existence in this field of research, a survey is conducted of the status of research and development of information interface techniques primarily at Stanford University, and a report is made thereon. Also reported is the information obtained at Technology and Persons with Disabilities Conference 1999. The result of a survey of the trend of research and development of the smart house under the TIDE (Technology Initiative for Disabled and Elderly People) project and the result of a survey of an information standardization project for equipment control in Europe are reported, and the result of a survey of the approach of Kyoto's welfare apparatus distributors to the development of equipment is made known.

    In this study, seismic monitoring of injected gas in a carbonate reservoir was investigated using multidisciplinary approach which consisted of geological/reservoir modeling, reservoir flow simulation, rock physics and seismic modeling. A case study was conducted over Lower Cretaceous carbonate reservoir offshore Abu Dhabi. The gas saturation and reservoir pressure data were obtained from the reservoir flow simulation. The velocity data of dry rock samples under the various conditions were also obtained from rock physics study. These outputs were converted to the velocity model using Gassmann's equation. The calculated velocity from Gassmann's equation is well correlated with velocity from laboratory measurements. Therefore we con confirm that the Gassmann's equation is applicable to estimate the velocity of the gas saturated reservoir rock. Based on the velocity model, synthetic seismic sections before and after gas injection were constructed in order to verify the influence of gas flood. As the results, amplitude difference between the two synthetic seismograms was observed at top and bottom reflectors of the reservoir zone. This amplitude variation is caused by both gas saturation change and pressure change. Although further investigation is needed to detect the cause of the variation, this study indicates the possibility of seismic reservoir monitoring. (author)

    Studies are conducted on three subjects, which are the development of 1) high-temperature energy materials technology, 2) ultrasophisticated materials technology, and 3) high-performance active materials technology. Under subject 1), high-strength porous materials are to be developed, which are resistant to heat and corrosion, tolerant of damage and deformation, and light in weight. In addition, relative to fluid transmission, materials are to be developed, which are highly resistant to heat, corrosion, and thermal impact, and capable of separating and removing particulates of powder dust. Under subject 2), efforts are under way to develop two technologies, related to materials creation and their application. The former technology involves the development of a process of simultaneously equipping materials with high wear resistance, desired friction factors, and desired mechanical and thermal characteristics; a process of equipping them with a trace damage detecting function; and a process of simultaneously equipping them with functions of restoration from accidents and of self-lubrication. Relative to the latter technology, efforts are conducted, in coordination with the endeavors for the above-said materials creation technology, to develop materials and their application with attention paid to some specified functions. Under subject 3), self-complete type ceramic materials not requiring an external driving power source are to be developed, in which a selective cleaning function and environmental energy conversion function are amalgamated.

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

    This study was performed to clarify the mechanism of mixture formation at peripheral area of diesel spray with PIV technique. Two dimensional cross-sectional photographs of diesel spray were taken with double pulse laser sheet. Local fuel spray particles were analyzed with an auto-correlation method and velocity vector and vorticity of the fuel spray particle were obtained. The vortex number increased and vorticity scale became smaller and its value grew higher with both smaller injection nozzle diameter and higher fuel injection velocity. With this injection condition, the mixing of fuel spray with ambient gas seems to be improved and the turbulence is expected to increase in the regions of higher vortex number, higher vorticity and smaller vorticity scale. Based on above results, the branch-like structure of diesel fuel spray was considered to be caused by vortices which formed in the shear layer between the spray and the ambient gas. 14 refs., 18 figs., 1 tab.

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

    This research project aims to establish a technique for crystal growth using pressure as a principal control parameter, and combining it with a microgravity condition, to develop a novel process material fabrication. Since the solubility of materials depends on pressure, it is possible to control a supersaturated condition for crystal growth by changing pressure. The growth condition can be controlled precisely, which is not possible by conventional methods that vary temperature and other factors. On the other hand, because a concentration diffusing field is formed autonomically around crystals in association with their growth, density convection is generated under gravity as a result of difference in the concentrations, making the growth conditions severely complex and uncontrollable. Ideal crystal growth condition control may be possible if the pressure control is performed under micro-gravity by which generation of the density convection can be suppressed. Realization has been achieved on in-situ observation by using high-magnification microscope which uses a diamond anvil cell, development of a hydraulic type optic pressure cell, and a high- speed crystal growing technology by means of pressure control utilizing the cell. New findings were also obtained on effects of pressure on crystal forms, and the pressure induced solid phase transfer mechanism. 67 refs., 49 figs., 3 tabs.

    Newly designed grout-filled coupling sleeve is discussed, which uses as the sleeve an electric resistance welded tube with protrusions formed in a checker pattern on its inner wall and is capable of using various premixed grouting materials available on the market. Specimens are subjected to uniaxial tensile loading and positive/negative cyclic loading, and the impact of various factors on the basic performance of the specimens and their stress/distortion characteristics at local spots in the reinforcing bar are disclosed. In the positive/negative cyclic loading in the plastic region, however, such findings are not obtained. In view of the stress/distortion characteristics at local spots in the reinforcing bar, a method is proposed for estimating the coupling strength and fracture type. A method for estimating the deformation behavior of the coupling, however, is not proposed. Investigations are conducted into the manufacture and installation of the grout holding framework, coupling fixing jigs, plugs, etc., and it is found that precasting should be studied in the future. 38 refs., 156 figs., 30 tabs.

    This paper describes efficiency improvement in wastewater treatment to separate SS component using anaerobic fermentation with fixable microorganisms and multihole glass separation films. Measurement of microorganism deposition on microporous PVF resin in a fermentation tank revealed that hydrophilic resins with smooth surface have better deposition, and the suitable carrier hole diameters were from 300[mu]m to 500[mu]m. Adding slightly-soluble carbonate when bacteria are fixed collectively is effective in preserving the entire methane fermentation reaction system and stabilizing the carriers. A composite film comprising SiO2-ZrO2-based porous glass made by using a sol-gel process and porous ceramics had the maximum desalination rate reaching 90%. The permeation rate at a film thickness of 2[mu]m was 46 times as much of that for 500-[mu]m single-layer porous glass. As a result of reforming the pore surface by introducing -Si(CH3)3, the film has turned affinitive to non-polar solvent, repelling water to permeate. In an experiment for fermentation liquid permeation of separation film composite bioreactor using digestive sludge, the higher the SS particle concentration, the more the initial clogging was difficult to occur. The film permeating flow velocity showed a maximum value at hole diameters of about 0.2[mu]m. 3 refs., 6 figs., 2 tabs.

    A coral skeleton is sampled at Kenya`s Malindi National Marine Park situated west of the Seychelles, and it offers information about the Afro-Asian monsoon. An X-ray profile of the specimen discloses the seasonal variation in the density of the coral skeleton. The oxygen isotopic ratio, which is generally affected by the seawater oxygen isotopic ratio composition which is dependent on the surface layer water temperature and fresh water, is found dominated, in the coral skeleton, practically by the surface layer water temperature. Accordingly, the oxygen isotopic ratio represents the seasonal and annual variations in the surface layer water temperature. It is inferred that the emergence of Ba/Ca ratio peaks in December into January reflects the presence of Ba from rivers, and there are indications that the Somali current has transported water to the coral sampling area from the Galana River which is the greatest river in Kenya. Five of the Ba/Ca ratio peaks coincide with peaks in the UV fluorescent band, which is attributed to the presence of terrigenous organic matters. The ENSO and Asian monsoon phenomena are estimated on the basis of the findings described above. 11 refs., 6 figs.

    The slow excitation response type power generator is studied when the rotor and stator of a 70,000kW-class model are combinedly subjected to an on-site verification test, when a good result is obtained. The rotor is disassembled for inspection, and its members are found to be sound without any problem in terms of mechanical strength. The quick excitation response type is studied when a 70,000kW model is experimentally built and subjected to an on-site verification test after a rotation and excitation test in the factory, when the pilot machine concept design is reviewed. In the study of a total system, efforts continue for the review of the model machine test method, improvement on generator design and analytical methods, development of operating methods, and the effect of its introduction into the power system. Since a He-refrigerated system is requested to exhibit high reliability for application to power equipment and to be capable of continuous long-period operation, a system having constituents with their reliability enhanced and an appropriate redundant system is developed, and a verification study is under way which will continue for more than 10,000 hours. Described also is an oil-free low-temperature turbo refrigerator. The latest quick excitation response type rotor is also tested for verification. (NEDO)

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

    Proportional, integral and derivative (PID) controls are used for a steering system and a main engine control unit installed in a vessel. Among them, this paper describes effectiveness of a PID gain tuning method using a limit cycle by means of relay control which is safer and simpler than conventional limit sensitivity methods. The present method was applied to an actual marine control system to conduct an actual vessel experiment. As a result of applying the method to a bow azimuth control system using a rudder, a new azimuth setting was set with an overshoot of 1.6 degrees in a ten-degree azimuth changing experiment. With respect to direction maintaining steering performance, the present method was capable of controlling the direction at a speed loss to about 80% of the ship`s autopilot. As a result of applying the method to a bow azimuth control system using a bow thruster, direction maintaining and changing control was realized in a low speed range in which rudder effect is lost. As a result of applying it to a main engine governor system and performing control of main engine rotation speed, it was found possible to derive control gains in a safe state without applying an excessive load to the main engine both under load and no load conditions. 14 refs., 8 figs., 11 tabs.

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