    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 introduces the prospecting and visualization technology cultivated in Denchuken (Central Research Institute of Electric Power Industry). The fluctuations in underground gas, underground water, gravity, terrestrial magnetism, and terrestrial current are information from the earth. The change in underground structure, underground water movement, and underground properties can be grasped using this information. With the progress of electronic engineering, a geophysical exploration method has been rapidly developed in recent years. This method is the most advanced technology in many ground examination methods. In the Denchuken, the following methods have been put to practical use between the shallow section of several meters under ground and the deep section of several kilometers. An underground radar method, seismic prospecting method, electrical prospecting method, CSAMT method that estimates the position of geothermal sources or faults by electromagnetic waves, TDEM method, and AE method that destroys the rock at the depth of the ground and detects by slight sound. Moreover, a geotomography method that can visualize the ground depth in precision using a bore hole by nondestruction executes the tomography based on specific resistance, elastic waves, electromagnetic waves, and percolation. 127 refs., 94 figs., 4 tabs.

    A glow-assisted ignition system tends to suffer from poor ignitability and slow flame propagation at low load in a direct-injection diesel engine fueled with methanol. To investigate the ignition process and improve such disadvantages, methanol sprays, their ignition and flames were visualized at high pressures and temperatures using a modified two-stroke engine. The results show that parameters influencing ignition, the location of a glow-plug, swirl level, pressure and temperature are important. In addition, a full kinetics calculation was conducted to predict the delay of methanol mixture ignition by taking into account 39 chemical species and 157 elementary reactions. 3 refs., 9 figs.

    The flow field around a Darrieus wind turbine is studied by flow visualization and PIV measurement in a rotating frame of reference to understand the unsteady nature of dynamic stall appearing at low tip-speed ratios. The qualitative nature of the dynamic stall observed by the flow visualization using dye injection technique is quantitatively reproduced in the instantaneous velocity distributions around the blade measured by PIV technique. These results indicate that two pairs of stall vortices are generated in one cycle of the turbine rotation and they grow in size as the tip-speed ratio decreases. The mechanism of the dynamic stall is found to be due to the flow separation over the suction side of the blade followed by the generation of in-flow motion from the pressure side to the suction side of the blade through the trailing edge.

    The flow patterns in shaking vessels with various geometries were visualized with a tracer method using aluminum powder. The spherical and conical vessels were effective for the shake mixing in the same manner as the cylindrical vessel, because these vessels have circular cross sections that develop the rotational flow. Neither a rectangular vessel nor a cylindrical vessel with baffles should be used for shake mixing, because rotational flows are not developed in these vessels. 2 refs., 6 figs.

    The latest measurement equipment and repair method were introduced into the work area of all refractories in the process of torpedo cars, hot metal preliminary treatment, hot metal pans, secondary refining, and cast pans so as to improve the cost of the newest advanced steelmaking refractories. As a result, the refractory cost could be reduced by 10%. This paper introduces the improvement in RH refractories and refractories for hot metal preliminary treatment. As for basic items, in addition to the visual observation, the thickness of refractories was quantified using equipment (laser profile meter, thermotracer, and NS sensor) for the furnace stop in the minimum remaining length. An ITV was also installed in the facilities where the visual check is difficult to carry out. Repair is mainly done by spraying. A thermal spraying repair method with high durability was used for the repair. A method that relieves a thermal shock was used for preheating. Moreover, measures that make the temperature gradient in the thickness direction uniform by using newly developed microwave drying equipment were taken for drying of unburned refractories. 4 refs., 13 figs., 2 tabs.

    Recently, a fault diagnostic expert system was prosperously developed as an objective of chemical plants and nuclear power plants. In this paper, a fault diagnostic method using modularized knowledge was proposed, a fault diagnostic system was constructed for an experimental plant, and the effectiveness of this method was clarified by carrying out a fault diagnostic experiment. The characteristics of the proposed fault diagnostic system were as follows: The necessary knowledge for diagnosing faults was made into each process element. Based on this method, the revision and addition of a knowledge base could be carried out in each element, and the design change of a plant could be flexibly corresponded by only changing the related part of the process flow graph. The estimated results were stored into the working memory, not only faults of an element in which faults resulted could be estimated, but also the fault propagating path could be clarified. 8 refs., 6 figs., 3 tabs.

    A devastating earthquake measuring 7.2 on the JMA (Japan Meteorological Agency) magnitude hit the southern Hyogo Prefecture on January 17, 1995. This earthquake, the worst in Japan since the Great Kanto Earthquake in 1923, brought great disaster and destruction to the Hanshin area and Awajishima Island. Most of the damage to concrete and steel structures occurred in buildings designed according to former building codes. Fewer collapses occurred in buildings designed under current building code that have more severe seismic requirements. Existing buildings should be assessed by their seismic potentiality, and retrofitted to escape damage in severe earthquakes such as the Great Hanshin Earthquake. New technology for assessing and retrofitting existing buildings was developed to improve resisting performance in response to severe earthquakes. Earthquake Load or motion exceeding current requirements can be supplied to assess and retrofit existing buildings if a client wants their buildings to exhibit much stronger seismic resistance. The retrofit technologies, such as a base isolation system for whole building, vibration control bracing system with steel damper, and base isolation floor system for computer equipments, can be applied to existing buildings. 11 refs., 9 figs., 8 tabs.

    In order to complement an anomaly diagnosis system by analysis of gases in oil for transformers, the analysis/diagnosis method of trace constituents in oil was developed. Liquid-liquid solvent extraction using methanol aqueous solution as extract, and high-speed liquid chromatography were adopted to analyze decomposed products dissolved into oil by over heating as trace constituents. The relation between over heat temperature and the amount of decomposed products by over heating was studied by simulation experiment of over heat anomaly. The detectable duration of anomaly after its generation was also studied by examining the adsorption phenomenon of the thermal decomposed products onto insulating materials. As a result, the criterion of the analysis/diagnosis method was prepared by using 5-hydroxymethylfurfural as index constituent of over heating anomaly. Although furfural was also effective as index constituent, it was excluded from the index constituent because furfural is formed by deterioration of transformers even during normal operation. 2 refs., 19 figs., 7 tabs.

    The high-precision diagnosis for deterioration of a breathing transformer containing an adsorbent was investigated. An adsorbent (activated alumina) may be contained in oil to eliminate the deterioration product in insulating oil or the moisture. In this case, the deterioration component furfural in insulating paper is adsorbed. The concentration in furfural oil cannot be thus used for deterioration diagnosis. Acetone and furan with good relation between the adsorption characteristics for activated alumina and the insulating paper deterioration in an accelerated deterioration test can be effectively used as a new deterioration index component of insulating paper. The disassembly survey showed that acetone is valid as the index component of deterioration diagnosis. Furan is not detected in a breathing transformer, but effective in diaphragm-type and nitrogen-sealed transformers. The adsorption of acetone by activated alumina requires no correction for the change in oil temperature at about 10{degree}C. The solubility of acetone for insulating oil is 60 times at 20{degree}C as high as CO2, and the discharge rate from a breather is little (1/25). Therefore, acetone is much more excellent than CO2 as the precision of a deterioration index. 21 refs., 15 figs., 4 tabs.

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

    The diagnosis method of aging deterioration was proposed for oil filled transformers based on detection of furfural in insulating oil. Vacuum, oxygen-added and water-added specimens of insulating paper immersed in insulating oil were thermally deteriorated at 120-180 {degree}C for 1-120 days to measure average polymerization degrees of the insulating paper and furfural contents in the oil and paper. As a result, the addition of oxygen or water accelerated forming of furfural, and the average polymerization degree considerably decreased in the early stage of heating. There was also the certain relation between the furfural content and average polymerization degree. In addition, various kinds of subjects were discussed which were required to apply these experimental results to diagnosis of aging deterioration in real oil filled transformers, and rough furfural contents corresponding to aging deterioration degrees of the insulating paper were given. As combined with a CO{sub 2} + CO method, the proposed method was expected to be more reliable. 9 refs., 8 figs., 2 tabs.

    Structure and velocity measurements using magnetic resonance imaging (MRI) have been performed experimentally to obtain a correlation between pore structure and interstitial flow through the packed bed of 5 mm diameter in the tube of 36 mm ID. To measure axial velocity maps of water flow through the packed bed, the phase method of using the phase difference of water spin magnetization between flowing and stagnant fluids by applying magnetic fields with bipolar gradients was employed. The spatial resolution of the obtained map in 0.2 mm x 0.2 mm x 0.5 mm. It was made clear from the obtained axial velocity maps that channel flows with higher axial velocity were induced not only near the wall but also in the internal region of the packed bed. Furthermore, pore structure of the packed bed was characterized from multi-slice images by partitioning of void space and combining of each pore section along the axial direction to analyze the structure-flow correlation. It was found from image analysis that axial channels with long and straight void space existed in the pore structure, and that most of the channel flows with higher axial velocity were induced in the axial channels. The flow rate through an axial channel depends on the square of the averaged cross section of the axial channel. (author)

    The research and development project is conducted to develop new methods directly related to early discovery of potential cancer patients, and the FY 2000 results are reported. The FY 2000 efforts are directed to improvement of intra-Alu-PCR method as the superhigh-sensitivity quantitative method, almost established in the previous fiscal year, to have higher reliability and simplicity suitable for automatic diagnosis. It is concluded that (there is no difference of significance between normal persons and cancer patients in free DNA concentration in the blood, determined by the Boyle/intra-Alu-PCR method), but this method is confirmed to be useful for prognostic monitoring of the patients who have the marrow or peripheral vessel cell transplant. Detection of qualitative gene abnormality of DNA in the peripheral vessels is investigated using the K-ras, p53 gene. Certain results are obtained by the MSA method for the former, and by the newly introduced WAVE DNA fragment analysis system for the latter. However, there are still a number of problems to be solved before these methods are applicable to screening for general medical examinations. The research on the (analysis of gene abnormality of cancer itself) has made a notable progress. (NEDO)

    To obtain the basic data to develop instruments for diagnosis of atherosclerosis and to elucidate the mechanisms of atherogenesis by focusing on the autofluorescence of blood and vascular walls of atherosclerotic animal models and human patients. We have performed experiments to examine the relationships between autofluorescence of blood and vascular walls of guinea pig atherosclerotic model and human patients and obtained the following results. 1. The autofluorescence from human atherosclerotic aorta included the components with longer wave length than normal aorta, suggesting that diagnosis of atherosclerotic aortic walls will be possible using spectroscopic analysis through glass fiber catheter into vascular system. Further studies should be needed to the quantitative diagnosis. 2. The autofluorescence from blood plasma of human atherosclerotic patients has showed that the peak wave length was shorter than that of normal plasma. This phenomenon was mainly caused by the oxidization of plasma, especially lipoproteins, LDL and HDL. 3. Atherosclerotic model of the guinea pigs was quite similar to human atherosclerosis at the points of cholesterol levels and localization of lipid deposit to arterial walls, and showed to be useful for the studies of atherosclerosis.

    The device is now satisfactorily capable of all image processing functions (bi-levelling, color deviation, brilliance adjustment, etc.) with the exception the karyotyping function. A substance that emits fluorescence by laser excitation is developed (for labelling the probe). A direct labelling method is studied, in which nucleic acid probes (nucleic acid labelled for chromosomal identification) will prove to be remarkably high in sensitivity. A new fluorescent reagent is synthesized, which is a BHHCT-4-dUTP to act as a nucleic acid probe. It is found that the new substance is superior to the conventional fluorescent substances in terms of stability and that all chromosomes may be forced into hybridization (selective combination of a probe with a peculiar chromosome) when various probes are labelled by this substance. A programing unit is constructed for a chromosomal aberration database. Items needed relative to chromosomes and parameters relative to chromosomal aberration data are appropriately arranged, and conditions to satisfy for their development into a database are studied. A rough design of an interface is complete. (NEDO)

    In solving the problems in developing technologies peculiar to developing countries, Japan will provide cooperation. This paper describes the achievements in diagnosis and survey in fiscal 1994. Development will be made on a manufacturing process for dimethylether (DME), a synthesizable and portable clean fuel, by using coal produced in China. Annual DME production of 10,000 tons will make it possible to supply 50,000 households with the fuel of one year consumption, whereas return on the construction investment and profit can be expected. At the Shanxi Coal Chemistry Research Institute, a 500 tons a year plant making DME from gasified coal gas is scheduled to begin operation. Development will be made on a pulp manufacturing technology in China, in which environmental pollution due to waste water is largely reduced, and operation cost is reduced. Application of the oxygen-alkaline evaporation and decomposition process developed in Japan will be considered, which uses non-wood raw material such as rice straw, wheat straw and megass). The raw materials are immersed continually in low-concentration alkaline solution, dehydrated, and then lignin is oxidized and decomposed by using oxygen in a continuous oxidation reactor to make the material into pulp. China uses non-wood materials as paper raw materials at 80%, whereas effects are expected in waste water pollution prevention, energy saving, resource saving and economics. (NEDO)

Sampling was conducted utilizing the materials as follows: 1) The survey on casualities of A-bomb exposed families in Hiroshima which was undertaken in 1946. 2) The survey of A-bomb survivors in 1965. 3) A-bomb exposed family survey conducted between 1973 to 1975. 4) Investigations of A-bomb victims exposed in the proximal areas from the hypocenter. From the above mentioned materials 470 pairs were selected, of which 220 were exposed. Among them 172 pairs were twins of the same sex. Female and male pair were also employed. In one case they were exposed, while the others were nonexposed. Two pairs were examined under the following methods: 1) Depth interview to ascertain familial casualities with reference to the family life cycle. 2) Socio-historical research. 3) Motoaki's Jinkaku Shindan Kensa (Modified Rorschach test by H. Motoaki), and T.A.T. test. Results obtained were summarized as follows: 1) Both pairs of twins were similar appearance, and also personality traits, and had a strong feeling of companionship for each other. 2) In family relationships, the persons studied were very conscious of the role expectations of elder and younger siblings in the twin pairs. 3) Through depth interview and projective test, A-bomb exposed pairs still showed deep psychological stresses, resulting from the A-bomb disaster. 4) Both among the exposed twins and within the nonexposed control group twin siblings had a close feeling of companionship for each other. However, nonexposed twins could not understand the psychological experience of twins who had been subjected to the atomic disaster. (author)
