    This paper considers authorization powers held by the major organizations in the EC, with the Maastricht Treaty kept in mind. One of the objectives of establishing the EC is to harmonize and develop the economic activities in the community on the whole, and promote making closer the relations among the member nations. The EC's supernationality has two aspects: finances (using financial sources from externally common tariffs as the EC's independent financial resources) and legislations (member nations delegating their own powers to the international organization). Organizations involving in the EC legislations are the European Assembly, the board of ministers, and the EC Committee. The Assembly has deciding powers at high levels on the EC budget decision, as well as vetoing power on the budget. The board of ministers is provided with deciding powers to assure achievement of the objectives defined in the official requirements. The Committee has a supernational character that each committee member can act independently free from being subjected to orders from his or her native country. Practically, however, the authorization relationship among the organizations has confrontations over the interests of the organizations and member nations. There have been such movements in this situation as the Luxemburg compromises, actions at the agricultural ministers meeting, and preparation of the unified European protocol. 2 figs., 4 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 intermittent aeration and circulation method is used frequently to destruct temperature stratification in a reservoir to prevent it from eutrophication. This method uses a cylinder erected in water, into which air bullets are shot out intermittently to circulate and mix heavier water mass upward. The present study has performed numerical analysis on the process to mix density stratifications by operating an intermittent water lifter cylinder for an extended period of time, and discussed responses of each factor to variation. The numerical computation has been carried out according to the equation of motion for water and air in the water lifter cylinder, and the numerical model that hypothesizes the double plume after air bubbles have departed from the water lifter cylinder. The result indicated that the amount of hypolimnitic water lifted against the amount of air injected can be expressed by an empirical formula that uses only the relative air bullet volumes. An evaluation formula for the water lifting efficiency has also been derived. It has been found for the stratification mixing that trends in the mixing efficiency can be identified by two parameters of dimensionless air bubble amount and stratification strength. 17 refs., 11 figs., 4 tabs.

    Since IP network does best effort behavior fundamentally, it always generates delay time and delay variation. For this reason, IP network has been unsuitable to transmit real time data such as a voice. However, in recent years, the technologies which transmit real time data in IP network, e.g. VoIP, have spread. If it is possible to transmit the existing electric power utility communications in IP network using these technologies, total network cost can be reduced by the reduction of required bandwidth and the simplification of communication network systems. In this report, it is examined quantitatively whether end-end delay time of the existing electric power utility communications, e.g. on-line, telephone, carrier relay, CDT (cyclic digital transmission equipment), video conference, ITV(industrial television), is within their permission delay time when they are transmitted in the best effort type IP network.

    A method for determining part re-use and recycling strategy in product design is considered for optimal design of total product life cycle based on the concept of Right Quality Products. For this purpose, it is important to be able to estimate part deterioration status under various product usage conditions. For supporting product designers' decision making about the product life cycle in preliminary design phase, the deterioration estimation is not required to be very exact, but to generate every possible deterioration modes qualitatively. Then, based on these deterioration modes, functional behaviour of target products is simulated, and possible product failure modes can be generated. By utilizing the FMEA (Failure Mode and Effect Analysis) method, the effects of failure modes are evaluated, and the results are fed back to product designers for confirming their design in terms of total product life cycle optimization. A basic methodology is considered, and case study has been done for a mechanical assembly of a one-time use camera. The assembly consists of injection molded parts. Various CAE methods have been used for predicting possible part failures due to initial residual stress, warp, fatigue, creep, and wear. Then kinematic and dynamic analysis of mechanical assembly has been done for detecting the effect of part deterioration on mechanism movements. Several critical failure modes have been detected, and the effects of those failures have been checked by the FMEA method. (NEDO)

    Drinking water contamination has become a worldwide problem. It is pointed out that re-evaluation of genetic damage with carcinogen is considered as an important problem particularly arsenic`s effects on health. To explain the genetic damage development mechanism of arsenic compound, results of the research conducted on the action of arsenic compound which develops during metabolic methylation process and inorganic arsenic are explained in this paper. The results of the study are summarized as follows. Arsenic genetic damage mutation is caused by dimethyl arsenic in main metabolism than inorganic arsenic. Lung DNA damage is induced by the interaction of O2 and arsenic peroxide radical. Dimethyl arsenic shows very important effect on lung cancer formation process which is induced based on 4-nitroquinoline-1-oxide (4NQO). It not only promotes lung cancer but it also plays an important role in malignant tumor`s mutation. 25 refs., 2 figs.

    At present, measurement of wet density and water content by radio isotope (RI method) is used for filling management. It is supposed for filling in road construction that putting-out thickness of banking material reaches nearly 1m in the future rapid construction, however, use of RI method is difficult because of inserting and installing of a radiation source rod, large measuring apparatus, and the legal regulation on radioactivity intensity. Application of resistivity measurement was thus considered. Since resistivity has the same parameter as compaction curve, and monotonously decreases with an increase in water content by volume, it is applicable as construction management index. The management reference of resistivity (Rm) is set by plotting of a compaction curve and corresponding resistivity curve, determination of the reference resistivity (Ro) corresponding to a maximum dry density and optimum water content ratio, and setting of the allowance to Ro according to soil or application. It was clarified that Rm is applicable as set for every filling material. 1 ref., 10 figs., 2 tabs.

    This technological development is intended to develop a process technology to dispose adequately of air bags convergently when they are removed from waste cars, with consideration paid on environmental and safety aspects. This technology that can dispose of air bags remaining as air bag modules (ABM) in large quantity and adequately can solve the problems of maloperation in opening them in cars and noise in conventional disposal methods. The recovery and disposal system using an inflator can be expected of reducing work load on dismantling contractors and enhancing the work safety. Furthermore, the energy saving process utilizing combustion of plastics can save resources. However, this technology has not elucidated how dioxins, dust, smoke, sulfides, and nitrogen oxides are generated and how the generation can be prevented. Therefore, an exhaust gas dioxin testing facility and an exhaust gas treating facility were installed additionally to the existing heating treatment facility to develop a disposal technology to treat adequately the exhaust gases generated when ABMs are disposed conveergently in large quantity, and treat the waste water discharged from the facilities. Fiscal 1998 has performed preliminary tests to accumulate fundamental data, and design and installation of the above two facilities. (NEDO)

    So as to determine the energy distribution of defect level density in a-Si, which is indispensable for an optimum solar cell design, the hitherto unclear theoretical relationship between the field effect method and MOS (metal oxide semiconductor) capacity method is made clear, and a unified theory is newly established. A high-speed totally automatic evaluation system is developed, capable of high-accuracy determination of defect levels. For the realization of an a-Si MOS structure required for fulfilling the above purpose, a-Si is grown and then diborane and ammonia are subjected to a glow discharge decomposition process for the formation of a new insulation film. It is found that the material may be utilized for MOS structure construction for defect density evaluation. Studies are conducted on plasma emission spectroscopy and infrared absorption analysis for the elucidation of growth mechanism for the growth of high-quality a-Si. Key radicals in plasma that govern film growth are investigated. It is disclosed that excited hydrogen in plasma plays an important part in microcrystalline phase deposition. It is also disclosed that hydrogenation greatly improves on CVD (chemical vapor deposition) a-Si doping efficiency. (NEDO)

    Xe/Ne plasmas are important for plasma display panels and VUV light sources. However, reactions between electrons and excited particles in the mixtures are so complicated that influence of the reactions on the plasma properties is not understood well. In this work, taking account of reactions through which electrons are produced, such as cumulative and Penning ionization, and of transition between excited levels, the electron and excited particle properties in Xe/Ne plasmas are calculated using the Boltzmann equation. The ionization coefficient and electron drift velocity agreed with experimental data. The influence of laser absorption in Xe/Ne plasmas on the plasma properties is also discussed. 25 refs., 15 figs.

    The paper described the result of the fiscal 1996 development relating to hydrogen combustion turbines, as one of the hydrogen utilization technologies, which have excellent environmentality and are expected of remarkably high efficiency. In the film cooling system of first-stage moving/stationary blades, the smaller the pitch of film pore is, the higher the mean cooling efficiency becomes, indicating 0.7 at maximum. As compared with the conventional shower head type, the metal temperature can be reduced 30-40degC. In the recovery type inner (convection) cooling system, by reducing the blade number, the consumption amount of coolant can be reduced 6% in stationary blade and 13% in moving blade, as compared with the result of the preceding year. In the element test of the hybrid cooling system, film cooling efficiency was actually measured by the porous module test equipment, and the result well agreed with the calculation result. In the water cooling system, studied were water (stationary blade) and vapor (moving blade) of the closed cooling structure for realization of a cycle efficiency of 60%. In rotor/disk cooling, analyses were made of seal characteristic grasp tests and characteristics of the rotor. The effect of deflection in the mainstream was small. Besides, proper value of the seal overlapping amount could be obtained. 6 refs., 368 figs., 55 tabs.

    Solid/liquid phase change in porous media has a wide relation with freezing and melting of ground bed, storage of cold heat in soil, and underground heat exchangers. This paper describes an investigation on the effect of density inversion on melting of ice in porous media by using the previously reported numerical analysis method. The high-temperature side temperature and the Darcy number were varied and investigated systematically on the ice in a porous media sealed in a rectangular container of which right hand side is maintained at elevated temperatures and the other three sides are insulated of heat. As a result, a large number of findings were obtained including the following matters: when the Darcy number is fixed at 4.01 {times} 10{sup {minus}5} and the high-temperature side temperature, Tw, is varied, the fluid descends along the high-temperature side because of the density inversion at Tw=4{degree}C, and forms one weak circulation that rotates clockwise; however, when the temperature reaches 16{degree}C, the circulation disappears, and a circulation rotating counterclockwise is observed, becoming identical to the case of a fluid where there is no density inversion; and change in the Nusselt number against the melting ratio, R, is the smallest at Tw=8{degree}C, and decreases monotonously with the R. 15 refs., 12 figs.

    For the development of high-efficiency, large-area, long-life, and low-cost solar cells, research is conducted on new methods of film formation and defect evaluation. Concerning the kinetics of Si thin film, a radical beam deposition method is proposed as a new low-temperature thin film growth method. Using the new method, a {mu}c-Si film is manufactured, through only a purely radical substrate surface reaction of chemically active, electrically neutral excited species. In research on the amorphous semiconductor superlattice, a new study is conducted on a multilayer, cyclic-structure superlattice consisting of thin films of a-Si:H and a-Si{sub 1-x}N{sub x}:H. In the research on an a-Si:H film formed by the direct photo-CVD (chemical vapor deposition) of disilane, the unit is improved and B and P are successfully doped by means of decompressed photo-CVD.

    Some of more important electrolytic solutions for Al electrodeposition are organic solvents, high-temperature type molten salts and low-temperature type molten salts having a melting point of 30{degree}C or lower, such as ethylmethylimidazolium chloride (EMIC). This study uses a molten salt of AlCl3-EMIC as the low-temperature type solution for high-speed electrodeposition. Discussed herein are the effects of melt temperature on limiting current density in Al electrodeposition and Al electrodeposit morphology. Limiting current density increases as melt temperature increases at any AlCl3 concentration used in this study. The AlCl3 concentration that gives the maximum limiting current density shifts from 64 to 67mol% at a melt temperature of 120{degree}C. A dense, smooth Al electrodeposited film results at a melt temperature of 100{degree}C or lower, but the electrodeposited grains become coarser as melt temperature increases. Melt temperature can be increased to 140{degree}C to secure a smooth electrodeposited film, showing possibility of 2 times faster electrodeposition than the conventional one. 21 refs., 12 figs., 1 tab.

Mentioned in the lists are the head office, directors, number of employees, line of business, contents of projects, the names of clients, etc., for each of 12 corporations including consulting firms and engineering contractors such as the Bechtel Pacific Corporation Limited. Named in the lists also are 17 manufacturers of pipes and tubes, pressure vessels, heat exchangers, tower tanks, steel structures and other fabricated metallic items, boilers, water treatment systems, pumps, electrical equipment, instrumentation, valves, iron and steel, etc. Furthermore, in relation with civil engineering and construction, 7 corporations including the Citra Constructions Limited are mentioned.

    A feasibility study is conducted on the assumption of introducing Japan's energy-saving technology into three leading paper and pulp plants in the Philippines for a reduction in greenhouse gas emissions. In the future, the effort will be associated with the clean development mechanism (CDM). The three target plants are TIPCO (Trust International Paper Corporation), UPPC (United Pulp and Paper Co., Inc.), and CCP (Container Corporation of the Philippines). The energy-saving facilities to be installed involve energy-efficient screens, variable-speed motors, conversion of winder unwinding sections into rheostatic brakes, hermetic design for dryer hoods, exhaust heat recovery facilities, etc. A study of the plant and equipment investment standards of the respective corporations indicates that energy-saving alone will not realize a full payback. It will be necessary, therefore, to have the project implemented as a CDM activity for a transfer from the Philippines of some CO2 emission reduced amount credit for Japan to bear a part of the necessary funds. Since the CDM framework and the value of reduced amount credit are not clear at the current stage, negotiations will have to be furthered about Japan's share of funds etc. as soon as the situation becomes clear. Since the Philippine Government is not well-disposed towards CDM, there is no possibility that this project will be approved as a CDM effort. (NEDO)

    Full Text Available To clarify the time course over which the human brain processes information about durations up to ~300 ms, we reanalyzed the data that were previously reported by Mitsudo et al. (2009 using a multivariate analysis method. Event-related potentials were recorded from 19 scalp electrodes on 11 (9 original and 2 additional participants while they judged whether two neighboring empty time intervals—called t1 and t2 and marked by three tone bursts—had equal durations. There was also a control condition in which the participants were presented the same temporal patterns but without a judgment task. In the present reanalysis, we sought to visualize how the temporal patterns were represented in the brain over time. A correlation matrix across channels was calculated for each temporal pattern. Geometric separations between the correlation matrices were calculated, and subjected to multidimensional scaling. We performed such analyses for a moving 100-ms time window after the t1 presentations. In the windows centered at < 100 ms after the t2 presentation, the analyses revealed the local maxima of categorical separation between temporal patterns of perceptually equal durations versus perceptually unequal durations, both in the judgment condition and in the control condition. Such categorization of the temporal patterns was prominent only in narrow temporal regions. The analysis indicated that the participants determined whether the two neighboring time intervals were of equal duration mostly within 100 ms after the presentation of the temporal patterns. A very fast brain activity was related to the perception of elementary temporal patterns without explicit judgments. This is consistent with the findings of Mitsudo et al., and it is in line with the processing time hypothesis proposed by Nakajima et al. (2004. The validity of the correlation matrix analyses turned out to be an effective tool to grasp the overall responses of the brain to temporal
