    Kansai Electric Power Co., Inc., has been working to elevate the distribution voltage of 6kV to 20kV, which is to respond to increasing demand for power. Using the experience of this approach, the corporation has designated Cosmo Square as a model area and plans to directly supply 400V to the area which is the voltage that clients demand. In this report, the plan is summarized and some examples of power receiving equipment newly developed for Cosmo Square are described. Cosmo Square has been developed to be a new base of international business, and lotting-out is now in progress. Upon completion, the center will be a group of gigantic buildings of which more than half will be creating a contract demand of 1000kW or more per building, and is expected to be consuming a total of 190MW finally. Power facilities under construction are to handle 20kV, and the voltage of 20kV will be stepped down to 400V for directly supply to 50-2000kW consumers. It is expected that, in this way, there will be various merits embodied, such as an extensive cost reduction in the construction of receiving equipment and other devices, efficient utilization of 230/400V appliances now in popular use, and reduction in safety-related expenditures. 4 figs.

    In the Kansai Tech, the distribution work sector was started under the network technology department with the introduction of new project system in 1996. The total sales in FY 1997 was 23.1 billion yen, which was 4% higher than that in the previous fiscal year. This paper describes the system and activities. For the characteristic technology development, a cable replacement method without cutting signals in the coaxial cable transmission line was developed in cooperation with the Kansai Electric Power Co., Inc. An uninterruptive wave operation method for the CATV transmission line was also developed for replacing equipment. In addition, an uninterruptive power operation method was developed for power lines. Furthermore, were developed a duct line positioning system using photo-gyro for the automatic measurements of embedded position of duct lines, an uninterruptive power oil sampler for estimating and supervising the anomaly of cables by sampling oil in the joint of OF cable line without cutting power, a mobile duct line inspection system, and duct line protection plates using used polyethylene tubes. These contribute to the development of the Kansai Tech. 1 fig.

    A large scale earthquake was frequently occurred in 1993, 94 causing many damages. Based on the consideration that the telecommunication network has an important role in such the disasters, various measures have been taken from the past. The basic ideas in taking measures for the telecommunication network against disasters are; (1) `Upgrading of system reliability` which includes the strengthening of equipment itself and the redundant composition of network, (2) `Prevention of communication stoppage` which enables to allow communication even when the system is damaged, and (3) `Early reactivation of telecommunication service` when the system is physically damaged. Some examples proved that these approaches taken from the past are effective in the recent seismic disaster. 5 figs., 1 tab.

    To know the trend of measures taken for global warming, conducted were overseas surveys, participation in academic society meetings, and literature surveys. The phaseout time of all ozone depleting substances responsible for the ozonospherial destruction was determined for both developed and developing countries in the 7th Meeting of countries which concluded the Montreal Protocol. As information on measures for protecting the ozonosphere, introduced was activities under United Nations Environment Programme (UNEP). New fluorine containing ethers were introduced as cleaning solvent which causes no ozonospherial destruction and is low in global warming index. Toxicity data were obtained on HFC-236ea and HFC-236fa which are promising substitutes in HCFC foaming and refrigerant fields. The paper introduced an outline of the 1st Meeting of countries which concluded the Framework Convention on Climate Change held in 1995. According to the report on the National Institute of Public Health and Environmental Protection of the Netherlands, the amount of emission of fluorine containing greenhouse effect gas (in CO2 conversion) reached 8-14% of all the amount of greenhouse effect gas emitted in 1990 unless the control is reinforced. An outline of the TEWI-3 project was introduced which is useful for comparing effects of substitution technologies on global warming. 14 refs., 11 figs., 29 tabs.

    This paper describes the progress and the major results of research and development on technologies and measures to prevent water pollution in China. Tests and researches have been performed on an upward anaerobic sludge blanket (UASB), a vertical baffled anaerobic sludge blanket, two-phase anaerobic digestion, and an anaerobic fluidized bed. When anaerobically digested sludge and aerobic active sludge are inoculated in the UASB, particle-shaped sludge was formed well in both sludges. This technology has begun to be used in breweries and citric acid factories. With anaerobic treatment of waste water containing sulfate, the sulfate was recovered as sulfur by using the first and second phases. Research and development is being progressed on the oxidation ditch technology as an improved version of the active sludge method. In a pilot test of a soil treatment system and a stabilization pond treatment system as alternative technology for the active sludge method, the BOD in the treated water was found 2.5 mg{times}1/l. Attentions are drawn on primary treatment, a living organism contact oxidation method, and a continuous filtration treatment process as technologies to turn polluted water into resources. 6 refs., 1 tab.

    With coal mines on the ebb, the technologies developed therefrom are beginning to fall into oblivion. Accordingly, a review was made from the present day viewpoint on the rock and water outbursts occurred several times at the Yubari Coal Mine at its development phase a water outburst accompanying rock outburst that occurs when a shaft gets close to a (high-pressure ground water bed). A fracture probability theory was used to determine the reason why a crater formed at a water outburst has a small opening and a great depth in the case of shales, and the other way around in the case of sand stones. The result was used in considering the specifications for water stopping constructions established in the past as the water outburst prevention measures, whereas such specifications having been improved on shales with the greatest uniformity were clarified to provide higher safety to other kinds of rocks. Examinations were also given on the flooding construction method used in constructing shaft bottom bulkheads as a provisional measure against a water outburst in a vertical shaft. This construction method could be applied to developing underground spaces at great depths. 8 refs., 16 figs., 6 tabs.

    Measures against Cryptosporidium parvum (C. parvum) in the waterworks are discussed. C. parvum is a pathogenic protozoan, and exists in the form of oocyst protected by a hard shell. It does not multiply in water or food, but does in human intestines and causes violent diarrhea and bellyache. A grave concern was created when many people were infected with the protozoan via tap water in Japan and the United States. Under such circumstances, ozone is used in an experiment to inactivate C. parvum. It is found that the C. parvum oocyst inactivation effect is evaluated by using a Ct value (disinfectant concentration Cmg/Ltimescontact time in minute) and that ozone treatment inactivates 90-99% of the protozoan. When various advanced water treatment technologies are being introduced for the purpose of serving safe and tasty water, the outcome of this study conveniently offers an ozone treatment method that will additionally inactivate pathogenic protozoa. Studies will be continued to elucidate the effects of factors of ozone treatment and water quality for the completion of an ideal disinfection process. Reference is made to an example of disinfection work implemented at a water purification plant of Milwaukie City, United States. 9 refs., 6 figs., 4 tabs.

    As for, countermeasures for chemical contaminants in a cleanroom air, the technical development has progressed earnestly since T top phenomenon of photo-amplified resist with basic gas due to atmosphere was pointed out in 1991 by MacDonald. Airborne-Molecular-Contamination (AMC) is classified into acids, bases, condensables, and dopants. According to SEMATECH no 95052812A-TR, condensable are defined as silicones or hydrocarbons with a boiling point greater than or equal to 150 degC. Water-soluble gaseous contaminants in outdoor air coming into cleanrooms are removed with a water spray equipment. AMC originated from circulating air in cleanrooms are prevented using various chemical filters. Conventional chemical filters made of activated charcoal, however, have several defects. Ceramic chemical filters developed by the authors are nonflammable, and consist of inorganic materials without any volatile organic matters and without alkaline metal and so on, and they have high removal efficiencies of condensable. 15 refs., 12 figs., 3 tabs.

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

    The tropospheric mixing ratio of nitrous oxide is increasing 0.25-0.31% annually. A number of studies have been carried out to describe global cycle of nitrous oxide. However, no clear cut understanding has been obtained. For example, stratospheric decomposition of nitrous oxide is significantly larger than the total emission from the earth`s surface to atmosphere. The imbalance suggests existence of unidentified sources. Recently, the tropospheric formation of nitrous oxide has been reported as a forgotten mechanism to provide nitrous oxide to atmosphere. However, its source strength has not been evaluated precisely. Possible error in extrapolating flux determinations at source sites to some large scale may be an additional reason for the imbalance. As nitrous oxide produced by different mechanisms differ in stable isotopic signature, measurement of stable isotope ratio is a way to re-evaluate the global budget. This report discusses the progress that has been made regarding stable isotope study on biogeochemistry of nitrous oxide. 22 refs., 1 fig., 1 tab.

    The seady flow and stability analyses of cavitation in flat plate cascades corresponding to 2, 3, 4 and 5 bladed impeller were carried out to find out all of the steady cavity patterns and destabilizing modes. For this purpose each blade is treated independently. In steady flow analysis the alternate blade cavitation was found only for impellers with even number of blades. It was shown that the alternate blade cavitation occurs since the local flow near the cavity closure reduces the angle of attack to the opposing blade when the cavity closure point approaches the leading edge of the opposing blade. For 2 or 4 bladed impeller, it was confirmed that there exists no additional destabilizing mode to those found in an analysis assuming inter-blade phase difference. It was shown that the modes with total cavity volume fluctuation depend on the inlet duct length while the modes without total cavity volume fluctuation are independent on the system. (author)

    This paper introduces the power supply facilities and the comprehensive power distribution automation system using an optical network installed at the Kansai International Airport that has begun operation. The power supply has adopted a three-line spot network system for the 22-kV system, a system to supply power from multiple number of distribution towers using a constant reserve system for the 6-kV system, and a system to supply power from high-voltage transformers for 100 to 200 V systems. As a conduit used to deal with subsidence of the power supply cable path, a pipe was developed that combines a PE-made flexible pipe with a cable protecting expansion steel pipe. The power distribution towers were given considerations for environmental harmony, size reduction, heavy salt damage, and measures for soft soil ground. The comprehensive power distribution automation system performs remote control of switches, operation of remote detectors, and load survey. Cost reduction has been realized in the system by adopting an optical multi-drop system that uses an air blown fiber (ABF) construction method. An optical shunt having eight branches was developed for this construction method. The ABF method blows optical fibers having two to eight cores into a hollow plastic pipe by using compressed air. 10 figs.

    When the recovered solar heat is supplied to demands such as heating, cooling by absorption refrigerator and hot water supply, the maximum available heating value was determined using a model in which solar heat collector was installed in the residence, to investigate the possibility of alternative demand. In this study, the supply temperatures were 80 {degree}C for cooling, 50 {degree}C for heating, and 50 {degree}C for hot water supply, where a flat plate type heat collector was employed. It was assumed that the heat storage can be conducted for 24 hours. Results obtained are as follows. For detached houses, most of the monthly demand can be supplied due to the actual predominant fine days in each month. For the cold and intermediate periods, it was supposed that monthly demand can be supplied by using excess heating value of fine days in the case of sufficient capacity of heat storage tank. For the model with heat insulating structure, demands except hot water supply can be supplied from solar energy. It was found that the heat insulation greatly contributes to the energy saving. 6 refs., 5 figs., 2 tabs.

    With respect to effects of technologies on reducing discharge amount of greenhouse gases (carbon dioxide, methane and nitrous oxide), assessments and analyses were performed on 420 techniques including energy saving technologies and new energy technologies. The energy conversion department requires further cost reduction by using such systems as LNG combined power generation using natural gas and high-efficiency coal burning thermal power generation. Requirements for paper and pulp industry include development and wider use of energy saving technologies over the entire manufacturing process, such as a direct causticizing technology and a high-performance recovery boiler. Problems in the cement industry are wider use of blast furnace cement and utilization of coal ash and tire wastes as raw fuels, and those in the iron and steel industry are energy conservation by use of coke furnace moisture adjustment and sintering cooler waste heat recovery. In the civil engineering department, introduction of heat and air insulating methods for buildings, and cogeneration operating on ceramics gas engines is expected. Use of oil substituting energy fueled cars is expected in the transportation department. 5 refs., 12 figs., 1 tab.

    The wear troubles of the water-supplying pump as well as water-supplying control valve due to the blocking-up of the strainer caused by the abnormal breeding of iron bacteria in ion-exchanged water have been occurring frequently since several years before in Oita Manufactory of Nippon Steel Corporation. The strainer provided in front of the pumps for supplying the water to each users are blocked up by the iron bacteria bred abnormally in the tanks of ion-exchanged water. Consequently, the cavitation phenomenon of water-supplying pump happens and the inside wear occurs. It is revealed by the results of the examination on the prevention countermeasure for breeding of iron bacteria carried out by the present authors that the destruction and the extinction of the cells are brought about by the concentrated electrification of the iron bacteria due to the electrification in the ion-exchanged water. In this paper, the principles, progress of study and development, the results of the practical tests in respect of prevention countermeasure for breeding of iron bacteria in ion-exchanged water by turning on electricity are described. The conventional means of frequency transformation are used in the experiment, and the betterment such as the increase of capacity of condenser is added because of the high electricity-resistance of ion-exchanged water. 13 figs., 1 tab.

In order to further promote the information exchange, and to make web sites user-friendly, fiscal 1998 has performed structuring a thesis renewal system. As a result of structuring the thesis renewal system, researchers can use the system as using a word processor by inputting data from a terminal in their laboratories. The data can also be made into a data base nearly semi-automatically. In addition to reducing time loss, delay and input errors because of re-entry, the researchers can make the data into a database on nearly a real time basis, and can provide their own theses to any part of the world through Internet. With regard to retaining Internet security, the security software having been introduced last year was renewed. In addition, detailed status such as daily access has become possible of identification as a result of introducing the net intellect. (NEDO)

    It is now demanded that water systems be positively improved to provide water high in quality and safe from pathogenic microbes such as C. parvum. According to a research in the U.S., ozone is the most effective among various disinfectants, and this is confirmed by a study of Fuji Electric Co., Ltd. The gist of the study is stated below. The inactivation effect in the assessment of the extinction of P. parvum oocysts is evaluated by use of the Ct value. In a growth activity test examining excystation conducted for C. parvum oocysts in the presence of a dissolved ozone concentration level of 0.05-0.5mg/L, the 90% inactivation Ct value is found to be 7-8mg/min/L, and the 99% inactivation Ct value approximately 12mg/min/L. In an infection test using mice, the inactivation Ct values are reduced to 1/3-1/2 from the values in the above-said excystation test, and this suggests that the scope of application of the ozone-aided disinfection process will further expand.

    Fundamental experiments were conducted on active noise control as sound insulation fence. This control method generates a sound source with the same amplitude and opposite phase as noise, and reduces noise through the interference of acoustic wave from the source. However, this method has too many problems with the three-dimensional sound field to be actually exploited in this environment. The following experiments were conducted to apply the active noise control to the sound insulation fence: one method of installing a geometric path along the inner side of the sound insulation fence used the acoustic delay process generated on the source side to attenuate the sound pressure level on top of the fence through interference of routing difference sound. The other method used an additional sound source attached to the bottom of the geometric path above to obtain a higher attenuation than using the simple sound insulation fence. At the second step, the active control duct model was used for the test. Then, the three-dimensional model test was conducted for active control of the sound insulation fence. The results of these fundamental experiments have indicated that each method can reduce the relative sound pressure level and the active noise control system using the acoustic phase difference can effectively reduce noise with dominant components in a low frequency band. There are still several problems with the three-dimensional mock-up model. 4 refs., 18 figs., 2 tabs.

    Some cases of poisoning by chemical substances are taken up, and counterplans are discussed. This report centers about the neurotoxic gas sarin incidents dealing with them as examples of acute poisoning caused by chemical substances. The important difference in terms of chemical structure between a neurotoxic gas and organo-phosphoric pesticide is that in the former phosphorus is directly bonded with carbon or halogen while, in the latter, bondage is represented by P-O-C, P-S-C, and the like, so bonded as to form the phosphoric acid, thiophosphoric acid, or dithiophosphoric acid. The result of the difference in chemical structure is that the neurotoxic gas easily gains access to the target enzyme and remains stable after bonding therewith while the organo-phosphoric pesticide is easily hydrolyzed by enzymes other than the target enzyme. Poisoning by neurotoxic gas or organo-phosphoric pesticide is clinically treated by the administration of atropine and 2-pyridine aldoxime methiodide which is an antidote. It is mandatory to let people clearly know beforehand the methods of analysis of chemical substances and their toxicity and to establish beforehand how to first-aid the victims and what emergency treatment can be executed. 11 refs., 2 figs., 2 tabs.

    This paper describes microbially influenced corrosion (MIC) on buried pipelines and its preventive measures. Major microorganisms involved in the corrosion include iron bacteria, iron oxidized bacteria, sulfur oxidized bacteria, sulfate reduced bacteria, and methane producing bacteria, which are largely divided into aerobic and anaerobic bacteria. There is high negative correlation between oxidation-reduction potential `E{sub h}` and pH of soils, and activity regions of each microorganism correspond to each region determined by E{sub h} - pH. According to the result of experimentally measuring the MIC rate in cast iron pipes, the rate was found to decrease in the order of iron bacteria > iron oxidized bacteria > sulfate reduced bacteria. As a first measure to prevent MIC, it is necessary to isolate pipes from soil. The present study disclosed that it is absolutely necessary to apply a coating having high insulation performance and take measures of cathodic protection, and that the corrosion may be prevented if the conventionally recommended anti-corrosive potential is cleared and electric current is flowing into defective parts even if a defect has occurred in the coating. 26 refs., 10 figs., 1 tab.

    The energy loss process in quenching of excited particles by collision to other ones and solid surfaces was investigated with metastable excited particles formed in weakly ionized gases. The measured lifetime of N2 metastable particles in N2, N2/CO, N2/CH3 gases during Townsent discharge did not agree with the Molnar's theoretical value which was obtained by solving diffusion equations using the boundary condition that assumes the density of excited particles to be zero at electrodes and tube walls. Strange behavior was observed too, that is, coefficients of diffusion and reaction rate determined by the theoretical lifetime change systematically with the distance between electrodes. Then, the novel boundary condition that takes reflection coefficient into account was applied to solve diffusion equations. The results obtained could account for experimental results without any discrepancy. The analysis of results clarified the dependence of various parameters of metastable excited particles on the reflection coefficient. The increase of reflection coefficient decreases the surface quenching of excited particles at electrodes and elongs effectively excited lifetime and increases the number of collisional quenching in gas phases. 16 refs., 8 figs.

    The Western European Regional Forum organized by the Energy Council of France was held in Strasbourg on 12 to 13 March 1997. Over 280 delegates attended the working sessions and the delegates were from not only Europe but also from more than 30 countries of North and South America, Asia and Africa. This kind of high attendance from different regions of the word clearly illustrates the value of such an event on the them which might have been considered by some as no longer of current importance. Pierre Gadonneix, Chairman of the Energy Council of France and Chairman and Chief Executive Officer of Gaz de France, introduced the problem. Whether West Europe face energy deficiency? As a sub text of this forum. The conclusion of the discussion was that Europe will not face energy deficiency. On the other hand, risk and threat do exist. These were the conclusions

    Kobe City and its vicinity has had great damages by the Great Southern Hyogo Earthquake, which cut into pieces the lifeline consisting of power lines, water supply, sewerage, gas supply and telephone lines at a lot of points, to cease their services in a wide region. Based on such a situation in the stricken area, an urban energy system has been proposed to respond to the disaster prevention. A regionally joint heat supply system using urban waste heat has been also introduced, in which the Kobe City area is modeled. Are illustrated major points of vision for the urban energy system in the future based on the precept from the great earthquake disaster. Electric power is the most preferential among the kinds of energy. Solar cells, co-generation and emergency power generators are the devices generating power independently. Considering the civil life at disasters, it will be required for individual refuges to have independent power sources. It will be also required that the devices are maintenance-free and can be easily operated by every persons. It is necessary to establish the life-spot energy system based on the photovoltaic power generation in individual spots. 8 figs., 4 tabs.

    This paper describes a method of noise prediction and reduction for an open-floored steel railway bridge. To facilitate noise prediction, the girder plate vibration levels and noise levels near the bridge were first measured while a train was running. Statistical Energy Analysis (SEA) and the measured vibration levels were then used to predict the radiated sound power needed to induce such a structural vibration. The sound power due to a running train could then be predicted. For noise reduction, the above information was used to predict the effectivity of a barrier plate set under the bridge girders. Damping plates were installed, and on completion of construction, noise levels near the bridge again measured. Measured results were found to be in good agreement with those predicted, and the barrier very effective in sound-proofing. (author)

    This paper describes indoor air pollution issue by chemical substances. The basic strategies include the use of building materials and application materials (adhesives and paints) with less emission of chemical substances, ventilation, and use of living goods with less emission of chemical substances. The indoor concentration of chemical substances shows a positive correlation with the amount of building and application materials emitting them. In general, it is highest at the completion, and decreases with time. The emission amount increases with temperature, and the indoor concentration decreases with the ventilation amount. These are greatly affected by the interior finish materials. Such chemical substances include formaldehyde, volatile organic compounds, termite-proofing agent, and plasticizer. The emission sources from life include furniture, curtains, carpets, insecticide and moth-proofing agent, wax, combustors, and smoking. For the construction, are significant the proper selection of materials such as adhesives and paints during design, and sufficient management during construction, sufficient curing and security of drying period, and ventilation before dwelling. For the bake-out method, room temperature is elevated, the emission is accelerated, and ventilation is conducted before dwelling. However, a part of this method has not been verified yet. The removal methods and decomposition methods are sometimes employed. 21 refs., 5 figs., 4 tabs.

    The origin of `Isoyake (ruining beach)` is not known enough, but in this paper this word means the phenomenon that the useful seaweeds such as tangle and undaria are extinguished suddenly and changed to various calcareous seaweed. The ruining beaches lie scattered widely from Hokkaido to Okinawa. The Marine science and technology center has begun the experiment for countermeasures, as the cooperative study with Aomori Pref., at a tangle fishing ground in north beach of the Peninsula Shimokita. Though there has been the removal method for seaweeds which blow the water-jet against rocks covered with seaweeds such as sargassum, limitation of operation by divers is at most 5m in depth. The operation depth of the new system developed this time is within 25m by applying a robot which is connected with a mother ship by a cable including three hoses for high pressed water (420kg/sq.cm), an optical fiber for TV and an electric wire. The width of one sweeping line was set to 40cm and the proceeding speed was set to 6-12 m/min. This experiment starting on June.1994, the facts of reviving from growing thick of sargassum on rocks to growing thick of tangle after next year have been observed. 10 figs.

    Offensive odor substances belongs to a quite different field from the perfume inspire of the same sense of smell, and is a substance forming a lot of troubles which is formed in intimate resident environments such as manufacturing factories of the chemicals, incineration and decomposition treatment process of living body relating substances, stock raising facilities, restaurants and others. A material called the offensive odor substance is generally in very low concentration in the atmosphere, most of which is ppm order in its detection limit. And, the offensive odor intensity is proportional to logarithm of its concentration. For example, even removing 99.9% of the offensive odor substance from its forming source, there is remained its difficult countermeasuring problem of no removing as its offensive odor. At present, the offensive odor is severely regulated by means of laws and acts, research on its relating field is active, and its relating publications have become plenty. In this paper, outline on recent state of the offensive odor and its measuring technique was summarized. 14 refs., 6 figs., 8 tabs.

    Emission amount of nitrous oxide (N2O) from anthropogenic sources is analyzed, and reduction effects by the abatement technologies are evaluated. The concentration of nitrous oxide in the atmosphere continues to increase and emissions from agricultural and ecosystem sources are drawing particular attention. For the emission of N2O in Japan, 8.28 Gg-N2O per year is emitted from fossil fuel combustion facilities, 6.95 from waste incineration facilities, 22.5 from transportation vehicles including automobiles, 26.7 from the chemical industry including establishments engaged in adipic acid production, 2.1 from sewage treatment facilities including septic tanks, 6.3 from farmland, and 7.1 from livestock excrement. For the N2O abatement technologies for different sources, fuel improvement, high temperature combustion, acceleration of reduction decomposition reaction, and development of catalysts are significant for the combustion technologies. In connection with N2O discharged in the process of adipic acid production, major businesses have internationally committed to up to 99% abatement of the N2O emissions by 1998. With regard to wastewater and sewage treatment facilities and septic tanks, improvement in COD/NO-N ratio, retention period, pH level, and reduction process is pointed out. 204 refs., 70 figs., 53 tabs.

    Discussions were given on measures to reduce N2O as part of the measures to prevent global warming. Nitrous oxide has a long atmospheric lifetime of 150 years, and its greenhouse warming potential will increase by 310 times that of CO2 after 100 years. It can also be a cause of ozone layer destruction. Nitrous oxide is estimated to have influence of about 10% as compared with CO2 even under the present conditions. Discharge of N2O from manufacturing process of adipic acid is aimed to be eliminated totally by 1998. Improvement in efficiency of combustion of fossil fuels and wastes serves most effectively to reduce not only N2O but also CO2. Nitrous oxide generated in sewage treatment as in sewage purifier may be reduced if the batch process is turned into a continuous process, but assistance from policy side would be required for wider adoption of the process conversion. No environmental regulations are applicable to N2O, whereas a problem is present that the number of system installation would not grow because of economic reasons even if the system is feasible technically. Another problem is that the N2O reducing technology is in trade-off relation with other warming gases such as NOx and methane. Comprehensive technological evaluations aimed at optimization must be moved forward in the future. 236 refs., 102 figs., 78 tabs.

    Loss processes of the nitrogen metastable molecule N2(A{sup 3}{Sigma}u{sup +}) in plane parallel electrodes have been investigated by us previously by solving the diffusion equation. Our procedure is based on an analysis using the third kind of boundary condition which can take account of finite values for the density of N2(A{sup 3}{Sigma}u{sup +}) at the electrode surfaces. The values of the effective lifetime of N2(A{sup 3}{Sigma}u{sup +}) calculated from this analysis were reasonably consistent with our experiments. This paper describes the behavior of the effective lifetimes of N2(A{sup 3}{Sigma}u{sup +}) in a cylindrical cavity. The analytical treatment of the diffusion equation for N2(A{sup 3}{Sigma}u{sup +}) proposed by us is extended to the three dimensional space. We report the nature of the effective lifetimes of metastable molecule in the cylindrical cavity systematically. 16 refs., 9 figs.

    Investigations and discussions have been given on energy saving possibilities at two medium-sized heat and power supplying plants in the city of Dailian in China. The project will improve the operation methods of the heat and power plants so that the energy cost can be minimized, and attempt to improve the boiler heat efficiency and save the energy by means of heat recovery and utilization. The draft modification plan for energy conservation has planned operation optimization for energy conservation, control of boiler operation under variable pressure, modification of the external boiler heat converter, use of inverters for the large capacity motors for boilers, and recovery of heat from the boiler blow-down water. In the analysis, models were structured from the operation data, and the effects of applying the energy saving measures were derived from simulation. As a result, the energy saving effect was found to be about 13,000 tons at the Chunhai plant and about 7,000 tons at the Pulandian plant annually (converted to oil). The reduction in greenhouse gas emission was found to be about 40,000 tons at the Chunhai plant and about 20,000 tons at the Pulandian plant annually. The number of years for investment payback is about 4.1 years at the Chunhai plant, and about 4.9 years at the Pulandian plant, wherein good profitability can be estimated. (NEDO)

    Under the project, an analytical tool applicable to the entire Asia-Pacific region is created. The tool enables the analysis of interrelations between economic/industrial activities and energy consumption in every country in the region, comprehension of the current status of energy consumption efficiency improvement, and analysis from a macroscopic viewpoint of trends in the Asian region as a whole, and thereby will contribute to the developmental enlargement of undertakings involving energy consumption efficiency improvement in the Asia-Pacific region. Based on 1990 Korean, Indonesia, Thai, and Philippine bilateral inter-industry relations tables, each vis-a-vis Japan, and energy input tables broken down by industry type and energy type, a database is prepared in which inter-industry relations tables and energy input tables are integrated. In conformity with the goals of the project, summaries are stated of the extraction of common classification, recombination of the Chenery-Moses inter-industry relations table, energy input table, and the CO2 emission table. It is found in a simulation that energy reduction in the four countries in 1990 amounted to 83,013 kilotons in terms of oil, equivalent to 25.7% of Japan's total endogenous energy consumption. It is suggested in the paper that the transportation department is the most important department for the industrial and energy-saving measures of the four countries. (NEDO)

    A coherent optical fiber communication method has possibility of large capacity transmission for future, but it needs a control of polarization state of optical signal. So it is important to clear the optical polarization characteristics of OPGW because the polarization state may change rapidly by alternative current or lightning. This report describes the experimental results of transient states of optical polarization and coherent transmission characteristics by large impulsive current in OPGW (200m length). The impulse current is maximum 16kA at peak and 1{times}10 us rise and tail time. Polarization states are measured by a real time stokes analyzer with 10 MHz band width. As a result, the maximum shift of polarization state on Poincare sphere is about 70 degree and the rise time is about 12us, which is much longer than current use time 1us. We found the reason that the polarization rise time is caused by the inductance of spiral current along twisted conductors of OPGW, which makes magnetic field along the fiber in OPGW so as to occur Faraday effect. The coherent optical FSK transmission characteristics in transient state of optical polarization by impulse current is also described. In the case of single detection, bit errors are caused when the polarization states of optical signal on Poincare sphere move about 150 degree from the polarization state of local optical source. And in the case of polarization diversity detection, bit error is not caused by any change of polarization. 7 refs., 31 figs., 2 tabs.

    Coherent optical fiber communication is an effective method to increase transmission capacity of the existing transmission route. However, it is necessary for this method to control the polarization state of optical signals. Composite fiber optic ground wire (OPGW) is a transmission route that is peculiar to electric power. It is considered that the optical polarization state through OPGW may fluctuate considerably due to the magnetic field generated by electric current. In this paper, it is predicted theoretically that the polarization fluctuation occurs due to the Faraday effect because the magnetic field is formed in the axial direction of the fiber by the spiral flow of electric current along the twisted strand around the fiber. In order to study the effects on the axial magnetic field, carried out is an experiment to add the axial magnetic field to the 10km drum-winding optical core wire through the toroidal coil. Both polarization rotation angle and ellipticity angle are changed up to 1.4 rad by the coil current of 10A. In the AC magnetic field, the bit error rate increases to 10{sup -2}, but it can be improved by the polarization diversity detector. 24 refs., 26 figs., 6 tabs.

    With relation to some global energy systems of which viability is predicted in the future, an evaluation was conducted from the viewpoints of economical efficiency, energy balance, CO2 emission, etc. The fossil fuel CO2 capture system, the conventional thermal power plant added with CO2 recovery/treatment facilities, is expected to reduce approximately 70-75% of the CO2 emission. The fossil fuel decarbonated hydrogen system, which decarbonates fossil fuels, recovers/treats CO2 at the place of fuel supply and uses as hydrogen, is of poor practical application from an economical point of view. The fossil fuel methanol synthesis system, which synthesizes methanol from fossil fuels at the place of fuel supply, generates electric power and recovers/treats CO2 with the methanol, is large in energy loss and CO2 emission and low in overall efficiency and CO2 reduction effect at the time of methanol synthesis. The renewable energy hydrogen system is an ultimate system with no emission of CO2, though it costs much. 110 refs., 83 figs., 107 tabs.

    The effect of the capacity change of the series capacitors on the turbine-generator shaft torque is analyzed and evaluated. The on-off timing of series capacitors is then investigated which restrains the initial amplitude of the shaft torsional oscillation produced by the stepped up change of the system reactance caused by the capacity change of the series capacitors. After the on-off timing is optimized, a controlling method for avoiding the capacity of the series capacitors produced by subsynchronous resonance (SSR) is proposed as a countermeasure to control the occurrence of SSR, and its effect of controlling shaft torsional oscillation is confirmed. This is a system to restrict the increase of the shaft torsional oscillation using series capacitors which are the cause for SSR production. In addition to the proposed stability improvement control, the effect of the shaft torsional oscillation control countermeasure is verified by EMTP simulation, and it is made clear that the shaft torsional oscillation countermeasure has no bad effect on the stability improving control. 13 refs., 17 figs.

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

When Kajima Construction Co. designed and constructed a pharmaceutical plant to manufacture injections to be exported to the U.S.A., it planned and executed the validation technique from the viewpoint of quality assurance of the manufacturing environment as the GMP qualified plant, hence in this article, the outline of the above is reported. With regard to application of GMP, differences between Japan and the U.S.A. are pointed out. Also systematization of quality validation of the manufacturing environment is commented upon. Furthermore, examples are shown concerning execution of validation, and the monitor facility corresponding to daily validation is described. 4 refs., 2 figs., 9 tabs.

    Electric power companies in Japan are making efforts to reduce the cost by improving the operation rate of existing facilities through the employment of advanced automation systems in the sector of distribution. This paper introduces the systems of Hitachi. A 22 kV-line automation system using high-speed photo-transmission line is adopted for the maintenance of widely extended distribution facilities. This system includes a 22 kV/240-415 V transformer and a 22 kV/105-210 V transformer. To supervise and control these transformers and switches, and to recover the accidents, this system consists of a computer system, a remote host station, and remote end terminals. Based on the information of distribution facilities of substations, end terminals and a host station, monitor/control of these facilities and recovery of accidents are conducted using computers. A system plan supporting system is also introduced, which aims at improvements of facility utilization factor, operation efficiency, and distribution operation efficiency. 5 figs.

    Tokyo Electric Power Co., Inc., has developed a new service system for power selling processes, which is to satisfy the needs growing increasingly versatile for advanced functions and higher efficiency. Out of the components constituting the new system, the overall power distribution management system is described here. In this system, information about terrain and facilities on drawings is converted to an electronic data base as geographic data. This geographical data is associated with numerical data of facility management and materials cost for enabling their unified utilization. This also enables the automatic estimation of materials and construction costs upon formulation of designs and further enables, upon the completion of construction work, the automatic updating of materials and construction costs estimation and of facilities and drawings. Furthermore, the system offers technical assistance by displaying such attributes as length and size upon receiving facility symbols representing electric poles or cables, by displaying the strength after automatically calculating the span, cable size, and line angle, and by displaying other construction processes if any scheduled for the same area. Since the new system fully shares data with the existing systems in intensified informative coordination, information may be retrieved at a terminal in any department. 1 fig.

    An arrester has a function for keeping the insulation of lines by discharging the surge over-voltage of thunderbolt into the earth. Zinc oxide type arresters with zinc oxide device as a characteristic element are mainly used. A 6,000 V-class arrester for distribution has been developed using an umbrella type polymer insulation vessel instead of a ceramic vessel usually used as a vessel for containing the zinc oxide device. This paper describes the structure and performance of this arrester. For this arrester, zinc oxide devices are stacked in the FRP cylinder and fixed by tightening them using a spring, which is covered by the umbrella type polymer insulator made of silicone rubber. When comparing with the ceramic vessel type arrester, its weight is a half, and its height is about 60%. Thus, light weight and down-sizing are realized. Basic performances such as working start voltage, limit voltage and thunderbolt surge working responsibility were verified. Exploration-proof performance, contamination-proof insulation performance, gas tightness performance and long-term performance were successfully verified, as well. 2 figs.

    With the demand for burying distribution lines in the ground (`burying,` hereinafter) growing stronger, the efforts of Chubu Electric Power Co., Inc., for burying and cost reduction in this connection are described. Since the cost of the burying method is 20-30 times higher than that of the overhead method and it cannot be readily started upon a request, and it requires much time for repair in case of accident, burying needs to be executed in a reasonable way so that the occurrence of such problems will be kept at the minimum. Under such circumstances, plans have been developed since 1985 under the guidance of reports made by a committee constituted of people involved including persons of experience or academic standing. For instance, in the first period that ended in 1986, a total length of 1000km was buried mainly in big city central parts (with Chubu Electric Power Co., Inc., taking care of 125km out of the total). In the second period that ended in 1991, another 1000km was buried (with Chubu Electric Power Co., Inc., taking care of 57km), for which local governments paid for the construction of underground conduits. In the third period that is to end in 1999, efforts are under way to bury a length of 2000km using a C.C. Box (common cable box) technique. 2 figs.

    Summarized herein is an interim report on how power distribution facilities should be in the future and on measures for their cost reduction complied by the Agency of Natural Resources and Energy power distribution facilities deliberation subcommittee at the end of fiscal 1997. Between Japan and the U.S., there is approximately a 5-fold difference in cost of power distributed per amount of power sold. When the frequency and duration of accidental supply interruptions are compared between Japan and the U.S. or European countries, power supply in general is more reliable in Japan than in other countries. Japan should exert thorough efforts for cost reduction without ruining the high trust it has earned for its uninterrupted supply. Measures for utilities to take in this connection include the standardization and internationalization of the equipment they own, reduction in investment in facilities, formulation of appropriate plans, review of requests for construction works, establishment of flexibility in independent safety-related systems, and the promotion of automatization. The Government is up to simplify various procedures, enhance deregulation, and rationalize systems concerned. The schedule of implementation of various plans suggests that cost reduction tangible to consumers will realize in power distribution comparable to that in power generation where competition is being introduced. 4 figs.

    Most of large cities in Japan are situated at flood area of rivers. At these large cities, population, fortune, and central management function accumulate, and if a bank-damaged flood is occurred at the river, it is anxious for the flood to suffer a large damage to life, fortune, and social economy. And that, risk on a bank-damaged flood is always present. However, even when the bank-damaged flood occurs, destructive damage is no longer allowed and risk management countermeasure for controlling the damage to minimum is much desired. An object of this study consists in construction of a flood simulation model with high commonness and presumable behavior of flood-induced flow in the urban residential area and in study on a damage reduction countermeasure by using this model. At first, a fluid force acting to a house group with various arrangement was measured and a calculation equation explainable in unity for the measured fluid force was introduced. Secondly, on the flood-induced flow at the urban residential area, a common curve coordinate system was adopted to intend precise modeling of road nets and house groups and to construct the flood simulation model. 16 refs., 21 figs.

    The trend survey was conducted of global warming protection measures by participation in international conferences, scientific society meetings and lecture meetings, and by literature surveys. We participated in the international conference on ozonosphere protection measures. In the 9th meeting of the nations which concluded the Montreal Protocol, the strengthening of restrictions on methyl bromide was decided on. In the UNEP solvent technology selection conference and the OORG conference of the World Bank, reports were made on substituting solvents in Japan, activities supporting developing countries, and the developmental trend of urethane use foaming agent. In the international conference on ozonosphere protection measures, introduced were the present status of Japan`s ODA for developing countries and examples of success of the substitution in the solvent field. The paper included nine reports on CFC destruction technology related literature made public in the past one year. The paper also introduced a comparative study of de-HCFC substituting technology at U.S. Oak Ridge National Laboratory, U.S. EPA`s prediction of emission of fluorine 3 gas, the predicted value of HFC emission and trial calculation of contributing rate in all greenhouse gases by IIR, Green Peace and Elf Atochem, and NOAA`s measured data on SF6 in the atmosphere. 49 refs., 46 figs., 26 tabs.

    This paper presents the working machine, method and example of the newly developed SAVE composer method. The working machine of the SAVE composer method adopts a forced elevating equipment and rotating penetration equipment equipped with an auger motor for hydraulic forced penetration and elevation of a casing. The process of the SAVE composer method is composed of setting a casing at a proper position. charging material from a hopper to a casing, penetrating a casing up to a proper depth by the auger motor of the rotating penetration equipment, discharging material by extracting a casing, and re-penetrating a casing for compaction of discharged material. This method is free from noise and vibration because of no use of an excitor. This method was used for preventive measures against liquefaction at the coastal levee of Tsu-Matsuzaka harbor, Mie prefecture. As a result, nearly the same improvement effect as conventional SCP method, and considerable vibration reduction were confirmed. 3 refs., 12 figs., 1 tab.

    With an objective to save energy and reduce greenhouse gas emission, a project has been discussed to introduce a gas turbine combined cycle power generation system for effective waste heat utilization and a pellet coating facility into the direct reduction steel making plant of Ahwaz Steel Complex in the Islamic Republic of Iran. The project will have a waste heat boiler installed at the outlet of the MIDREX plant waste heat recovery device to link it with a gas turbine combined cycle power plant to structure a 42-MW power generation system. In addition, productivity enhancement was attempted by applying the raw material pellets with coating to raise the reduction gas blow-in temperature. The energy saving effect expected from this project would be saving of 63,140 tons of crude oil equivalent annually, and the greenhouse effect gas reducing effect would reduce 173,790 t-CO2 annually. Although the investment will require about 3.16 billion yen, the cost reduction amount in association with power generation is small because of the power purchase unit cost being as very low as 1.9 yen/kWh, making the investment recovery period 10.2 years. Therefore, the project will not be realizable economically. (NEDO)

    Safety measures and assessment technology were studied for the WE-NET project. As the study result in fiscal 1996, the information on safety design, anomaly and accident was collected and arranged. The information on safety measures, ideology and criterion was also collected by visiting some domestic and overseas organizations experienced about handling of liquid hydrogen (LH). The initial survey was made for the safety design ideology, analytical technique and disaster preventive measures of LNG systems as the similar cold liquid system. Accidents and explosion accident of a hydrogen production plant (water electrolysis) in Germany were analyzed. Events on storage tanks and leakage around the tanks were studied as typical risk of LH considering temporary and LNG system design information. The model based on the LH spillage test result and 3-D dispersion of vapor cloud were prepared by modifying a simulation code. The model allowed evaluation of the effect of explosion and fire accidents of compressed hydrogen gas and flying fragments on structures and people, and visual display of distances from a tank and damage conditions. 19 refs., 29 figs., 18 tabs.

    Coherent optical fiber communication method is effective for increase of transmission capacity of existing optical fiber. But it needs a control of polarization state of optical signal. Especially through OPGW (Optical fiber composite Ground Wire), the polarization state will be influenced by lightning. This report describes a field measurement of optical polarization characteristics in actual OPGW of Hokuriku electric company in the condition of lightning. Main results are follows; (1) In normal condition without lightning, the states of optical polarization have alternative fluctuations of 60Hz. (2) In lightning weather, the transients of optical polarization are detected 51 times in two half months. It is made clear that these transient states are due to lightning by checking the time of day with the time data of LLS (Lightning Location System) and with the time of power line trip. (3) By estimating the waves of polarization shift, the duration of transient is 2 - 5msec, the rise time is 50 - 200usec. and wave tail has damping oscillation of 2 - 5kHz. The maximum shift of polarization states on Poincare sphere is 165 degree, which means polarization changes almost opposite states. (4) By evaluating the locations of lightning with LLS data, the transient polarization shift is caused by lightning over 50 km from observed OPGW. And the short distance tends to the large fluctuation of polarization. This characteristics may have a possibility of application to lightning monitoring. 7 refs., 22 figs., 1 tab.

    A feasibility study of a model project was conducted on energy conservation and introduction of technology against pollution for Fe-alloy electric furnaces in China. The total production of Fe-alloy was 4.32 million tons in 1995, which recorded the maximum production. Out of which ferro-Cr occupied 9.5%. Production of high carbon ferro-Cr in 2000 is estimated to be 600,000 tons. China`s electric furnaces for ferro-Cr using carbon as heat source do not have covers and gas recovery systems. The gas from furnaces is burnt and wasted, which results in air pollution. To cover the furnaces, grading of powder materials is indispensable for improving the ventilation in furnaces. In Japan, sintering and pelletizing methods were developed. In China, the covering and gas recovery are performed for furnaces using expensive massive ores. In most cases, they are not performed. For three works at Jilin, Lioyang and Jinzhou surveyed in this project, recovered gas can be effectively utilized, which would provide energy saving and environment improving effects. They have enough site areas and workshops in the sites. Construction works can be conducted by China themselves. 6 figs., 32 tabs.

    Identification was intended on effects of such thermal factors as metabolic amount, environmental temperature and humidity, and clothing resistance on human body temperatures during works under hot environments. Therefore, measurements were carried out on human skin temperatures, rectum temperatures and humidity inside clothing, while amount of motion, environmental temperature, and clothing are changed in a constant temperature room and under a sun irradiation environment. Furthermore, a heat balance model was prepared, which divides the objects into an outer shell layer whose temperature changes depending on the result of this experiment and into a core having constant temperature characteristics. An equation to derive skin temperatures was introduced from the model. The equation formulated a calculation formula for heat accumulation in human body, which can be used as a hot heat index. Relationship between thermal factors and heat storage amount was investigated to consider a thermal limit for a physical work. An equation to derive skin temperatures was confirmed capable of expressing general change in skin temperatures, being proved by comparison with experiments. Calculation formulas for amount of heat stored in human body were shown capable of expressing influence of different thermal factors, the expression being useful as a hot heat index. Calculating the human body heat storage is very largely affected by effect of sweat to dissipate heat, hence it is necessary to improve the accuracy including that for body temperature adjusting reactions. 17 refs., 17 figs., 5 tabs.

    Discussions have been given on trends and countermeasures for resources problems from a viewpoint of wastes problems. Recycling is carried out in Japan for industrial wastes and general wastes in their own ways. However, the issue is the year-by-year increase in the quantity of products used. A conception of life cycle assessment has become used recently in environmental assessment of a certain product that its environmental load should be calculated on each of the processes of resources collection, transportation, manufacturing, sales, consumption, recycling, and disposition. The result shall then be totaled to assess the product. Experiences in the construction industry and the wastes disposition industry call for structuring a system of long-distance wastes transportation that utilizes railways and ocean vessels. Societies promoting a regeneration plant project have plans to improve model regeneration plants for construction wastes with joint efforts of construction companies. To leave beautiful environments to the next generation, it is necessary to have an awareness that rivers and roads flowing and going through a region are the properties of the people who live in the region. Environment can be preserved when everybody participates in the environment improving movement. 11 figs., 3 tabs.

    For the state-run plant of Pakistan Steel in Pakistan, an investigational study was conducted on energy conservation and reduction in greenhouse effect gas emission. In the project, energy conservation technology on the following was tried to be introduced: coke oven coal moisture control (CMC) equipment, sintering cooler waste heat recovery equipment, blast furnace hot stove waste heat recovery equipment, blast furnace pulverized coal injection (PCI) equipment, blast furnace top pressure recovery turbine (TRT) equipment, and hot strip mill heating furnace regenerative type burner equipment. Further, in the project on environmental improvement, studies were made on coke oven environmental improvement and blast furnace cast house dust collection. The results of the study indicated that economical effects of the energy conservation project were considered as low because the unit price of energy of Pakistan Steel is low. However, substitution of the low-priced domestic coal for the imported coal has a good effect, and energy conservation in the TRT power generation and by the regenerative type burner produces a highly economical effect. Therefore, Pakistan Steel also agrees to positively promote the project. Moreover, concerning the environmental improvement project, it was considered that the necessity of the project is high in the relation of the coke oven aimed at reducing emissions of toxic substances.

    This project is aimed at internationally cooperating in the R and D of industrial technology and improving industrial technology of Japan. For it, the following three technologies were investigated: 1) environmental preservation technology using biotechnology, 2) technology for effective use of unused hydrocarbon resource, 3) technology for development of environmental harmony type catalyst. In 1), a survey was conducted of applicability of biological surfactant to prevention measures of pollution by heavy distillate. It showed that part of the biological surfactants is reaching a stage of its being industrially produced by gene recombination bacteria, but as a whole, biosynthetic genes have hardly been elucidated. In 2), a survey of high-grade treatment technology of petroleum coke was made. It pointed out that it is necessary to develop a technology which makes the most of features of petroleum coke and allows defects. In 3), scientists and engineers of Japan and Europe searched for themes on which they can jointly study in the fields of NOx removal catalyst, up-grading of fuel, and development of catalyst combustion of fuel. 287 refs., 136 figs., 128 tabs.

    This project is aimed at internationally cooperating in the R and D of industrial technology and improving industrial technology of Japan. For it, the following three technologies were investigated: 1) environmental preservation technology using biotechnology, 2) technology for effective use of unused hydrocarbon resource, 3) solid electrolyte fuel cell (SOFC) technology for high-efficient electric vehicles. In 1), bio-remediation is a choice as the result of trially using technologies for remediation of the environment polluted by pollutant, but it is not a technically completed one, but one which will be improved by trial and error. By the application of gene engineering, the use of gene recombination enables wide spread of decomposition genes. In 2), technical subjects were studied such as superheavy distillate, oil shale, coalhead methane and methane hydrate. In 3), designed were cylinder type and planar type SOFC of 850degC operation and 10kW output. Accumulation and weight of a total SOFC system are 81 liters and 100 kg in cylinder type and 136 liters and 200 kg in planar type. The vehicle can be equipped with the SOFC. 171 refs., 72 figs., 54 tabs.

    Determination of modification degree in BDDE-modified hyaluronic acid (HA) hydrogel is of particular interest. In this paper, three crosslinking parameters (degree of total modification, t-MOD; degree of cross-link modification, c-MOD; degree of pendent modification, p-MOD) are defined and determined by quantification of the modified fragments in hydrogel digestion by size exclusion chromatography combined with mass spectrometry (SEC-MS). The digestion products of a novel hyaluronidase HAase-B produced by Bacillus sp. A50 are studied and only a few modified fragments are identified by (1)H NMR and MS. As a result, Three HA hydrogels prepared in lab have different t-MOD, c-MOD and p-MOD, but the ratio of c-MOD to p-MOD result in the almost same value of 75%. Hydrogel products from Q-Med have nearly same t-MOD about 0.8% and c-MOD about 0.1%, the ratio of c-MOD to p-MOD is about 13%. Hydrogels from ANTEIS S.A all have much higher t-MOD values, the ratio of c-MOD and p-MOD is about 8%.

    Full Text Available Abstract The Asian College of Psychosomatic Medicine (ACPM was founded as the Asian Chapter of the International College of Psychosomatic Medicine (ICPM-AC in Tokyo on April 12, 1982. The first president was Hitoshi ISHIKAWA (Japan, the vice-presidents were Mahalingam MAHADEVAN (Malaysia and Burton G.BURTON-BRADLEY (Papua- New Guinea, and the general secretary was Sueharu TSUTSUI (Japan. Five years previously, preparation for creation of the ICPM-AC was started at the 4th World Congress of the International College of Psychosomatic Medicine (ICPM held in Kyoto, Japan, September 5-9, 1977. The First Congress of the ICPM-AC was held by the President Yujiro IKEMI in Tokyo on May 19-20, 1984. The main members in the early stage were Y. IKEMI, H. ISHIKAWA, S. TSUTSUI, Taisaku KATSURA, Tetsuya NAKAGAWA. Hiroyuki SUEMATSU and others from Japan and Hsien RIN (Taiwan, Seock Young KANG (Korea, M. MAHADEVAN. B.G. BURTON-BRADLEY and others from other Asian countries. Thereafter, academic congresses of the ICPM-AC, the 2nd to the 9th, were held approximately every two years, in Japan, India, Malaysia, Taiwan, Korea, and China. The name was changed to the Asian College of Psychosomatic Medicine (ACPM, and the 10th to 14th congresses were held in Taiwan, Okinawa (Japan, Australia, Korea, and China. The current president of the Executive Board of ACPM is Chiharu KUBO, the Director of Kyushu University Hospital. The next academic congress is the 15th ACPM and will be hosted by Tserenkhuugyin LKHAGVASUREN in Ulaanbaatar, Mongolia from August 24-26, 2012. Participating countries have expanded to include Asian-Oceanic countries such as Mongolia, Micronesia, Australia and Sri Lanka. The main themes of the congresses have focused on psychosomatic disorders, culture - bound syndromes, oriental medicine, etc... To date,"Health promotion"by raising the level of mental health based on psychoneuroendocrinoimmunomodulation has been very important. Prevention is also
