Full Text Available The aim of the article is to analyze the change of the Russian Federation’s international image in the light of two significant events: the Olympic Winter Games in 2014 in Sochi and the annexation of Crimea. According to the first hypothesis, one of the main aims for hosting the Olympic Games was to improve the international prestige of Russia. Shortly after the Olympics Russia increased its activity in Eastern Ukraine, which resulted in the annexation of the Crimean Peninsula. Therefore the article is also aimed to investigate whether by annexing Crimea Russia squandered the possible positive effects of hosting the Olympics in terms of its international image.

Full Text Available This article examines ethno-demographic processes in the north-east Black Sea area, more specifically the territory of Greater Sochi, in the 19th – early 21th centuries. In writing the article, the authors have relied on archive materials from the archives department of the administration of the city of Novorossiysk and the archives department of the administration of the city of Sochi. The authors have consulted reference pre-revolution literature, Soviet-era and present-day population censuses, as well as the findings of present-day research studies. The methodological basis of this study are the principles of historicism, objectivity, and systemicity, which helps to get an insight into the general patterns and regional peculiarities in the demographic development of the major ethnicities in the north-east Black Sea area in the 19th-20th centuries. The authors touch upon the process of colonization of the territory and its ethnic composition. In the end, the authors come to the conclusion that the ethno-demographic picture of Greater Sochi had been forming in a complicated fashion. As a consequence, in the second half of the 19th century, following the Caucasian War, the territory had to be repopulated. Resettlement flows from different locations in the Russian Empire and overseas had formed by 1917 an ethno-picture that featured Russians and Armenians as two principal ethnicities. The authors note that this picture has not changed in a major way to this day.

Full Text Available Cardiovascular diseases are major reasons for population mortality in majority of countries, including Russia. Metabolic syndrome is considered to be one of the main pathologic states, leading to enhancement of atherogenesis, ischemic heart diseases and cerebrovascular diseases. Physical methods, including resort treatment play great role in metabolic syndrome prevention and treatment. Climate therapy depends on resort climate and season and is a major component of resort treatment. Psychological testing showed that combined resort treatment, using climate therapy of patients with stable effort angina at Sochi Health-resort is more efficient in autumn and of patients with metabolic syndrome in summer. The findings have been confirmed by clinic-functional indicators.

Immediate data access system for LHD experiments

International Nuclear Information System (INIS)

Emoto, M.; Iwadare, Y.; Nagayama, Y.

2004-01-01

Several kinds of computer systems are used to perform large helical device (LHD) experiments, and each produces its own data format. Therefore, it has been difficult to deal with these data simultaneously. In order to solve this problem, the Kaiseki server was developed; it has been facilitating the unified retrieval of LHD data. The data acquired or analyzed by various computer systems are converted into the unified ASCII format, or Kaiseki format, and transferred to the Kaiseki server. With this method, the researchers can visualize and analyze the data produced by various kinds of computers in the same way. Because validations are needed before registering on the Kaiseki server, it takes time to make the validated data available. However, some researchers need data as soon as it is gathered in order to adjust their instruments during the experiments. To satisfy this requirement, a new visualization system has been under development. The new system has two ways to visualize the data as physical values from the raw data. If the conversion task is not complex, the NIFSscope, a visualization tool, converts the raw data into physics data by itself. If the task is too complex to handle, it asks the ANACalc server to make physics data. When the ANACalc server receives a request, it delegates calculation programs to convert the acquired data into physics data. Because the interfaces between the server and the calculation processes are independent of programming languages and operating systems, the calculation processes can be placed on different computers and the server load can be reduced. Therefore, the system can respond to changes in requirements by replacing the calculation programs, and can easily be expanded by increasing the number of calculation servers

To describe the epidemiology of illness at the Sochi 2014 Winter Paralympic Games. A total of 547 athletes from 45 countries were monitored daily for 12 days over the Sochi 2014 Winter Paralympic Games (6564 athlete days). Illness data were obtained daily from teams without their own medical support (13 teams, 37 athletes) and teams with their own medical support (32 teams, 510 athletes) through electronic data capturing systems. The total number of illnesses reported was 123, with an illness incidence rate (IR) of 18.7 per 1000 athlete days (95% CI 15.1% to 23.2%). The highest IR was reported for wheelchair curling (IR of 20.0 (95% CI 10.1% to 39.6%)). Illnesses in the respiratory system (IR of 5.6 (95% CI 3.8% to 8.0%)), eye and adnexa (IR of 2.7 (95% CI 1.7% to 4.4%)) and digestive system (IR of 2.4 (95% CI 1.4% to 4.2%)) were the most common. Older athletes (35-63 years) had a significantly higher IR than younger athletes (14-25 years, p=0.049). The results of this study indicate that Paralympic athletes report higher illness incidence rates compared to Olympic athletes at similar competitions. The highest rates of illness were reported for the respiratory and digestive systems, eye and adnexa, respectively. Thus, the results of this study form a basis for the identification of physiological systems at higher risk of illness, which can in turn inform illness prevention and management programmes with eventual policy change to promote athlete safety in future editions of the Winter Paralympic Games.

To describe the epidemiology of injuries at the Sochi 2014 Winter Paralympic Games. A total of 547 athletes from 45 countries were monitored daily for 12 days during the Sochi 2014 Winter Paralympic Games (6564 athlete days). Daily injury data were obtained from teams with their own medical support (32 teams, 510 athletes) and teams without their own medical support (13 teams, 37 athletes) through electronic data capturing systems. There were 174 total injuries reported, with an injury incidence rate (IR) of 26.5 per 1000 athlete days (95% CI 22.7% to 30.8%). There was a significantly higher IR recorded in alpine skiing/snowboarding (IR of 41.1 (95% CI 33.7% to 49.6%) p=0.0001) compared to cross-country skiing/biathlon, ice sledge hockey or wheelchair curling. Injuries in the shoulder region were the highest single-joint IR (IR of 6.4 (95% CI 4.6% to 8.6%)), although total upper and lower body IR were similar (IR 8.5 vs 8.4 (95% CI 6.4% to 11.1%)). Furthermore, the IR of acute injuries was significantly higher than other types of injury onset (IR of 17.8 (95% CI 14.7% to 21.4%)). In a Winter Paralympic Games setting, athletes report higher injury incidence than do Olympic athletes or athletes in a Summer Paralympic Games setting. The highest incidence of injury was reported in the alpine skiing/snowboarding sporting category. There was a similar incidence of injury in the upper and lower limbs. The joint with the greatest rate of injury reported was the shoulder joint. Our data can inform injury prevention programmes and policy considerations regarding athlete safety in future Winter Paralympic Games. Published by the BMJ Publishing Group Limited.

2006-01-01

In order to unify various types of data, the Kaiseki Server was developed. This server provides physical experimental data of large helical device (LHD) experiments. Many types of data acquisition systems currently exist in operation, and they produce files of various formats. Therefore, it has been difficult to analyze different types of acquisition data at the same time because the data of each system should be read in a particular manner. To facilitate the usage of this data by researchers, the authors have developed a new server system, which provides a unified data format and a unique data retrieval interface. Although the Kaiseki Server satisfied the initial demand, new requests arose from researchers, one of which was the remote usage of the server. The current system cannot be used remotely because of security issues. Another request was group ownership, i.e., users belonging to the same group should have equal access to data. To satisfy these demands, the authors modified the server. However, since other requests may arise in the future, the new system must be flexible so that it can satisfy future demands. Therefore, the authors decided to develop a new server using a three-tier structure

Medical care in disabled sports is crucial both as prophylaxis and as ongoing medical intervention. The aim of this paper was to present changes in the quality of medical care over the consecutive Paralympic Games (PG). The study encompassed 31 paralympians: Turin (11), Vancouver (12), and Sochi (8) competing in cross-country skiing, alpine skiing, biathlon and snowboarding. The first, questionnaire-based, part of the study was conducted in Poland before the PG. The athletes assessed the quality of care provided by physicians, physiologists, dieticians, and physiotherapists, as well as their cooperation with the massage therapist and the psychologist. The other part of the study concerned the athletes' health before leaving for the PG, as well as their diseases and injuries during the PG. The quality of medical care was poor before the 2006 PG, but satisfactory before the subsequent PG. Only few athletes made use of psychological support, assessing it as poor before the 2006 PG and satisfactory before the 2010 and 2014 PG. The athletes' health condition was good during all PG. The health status of cross-country skiers was confirmed by a medical fitness certificate before all PG, while that of alpine skiers only before the 2014 PG. There were no serious diseases; training injuries precluded two athletes from participation. The quality of medical care before the PG was poor, however, became satisfactory during the actual PG. The resulting ad hoc pattern deviates from the accepted standards in medical care in disabled sports.

Sexual Orientation, Human Rights, and Corporate Sponsorship of the Sochi Olympic Games: Rethinking the Voluntary Approach to Corporate Social Responsibility

Full Text Available Multi-national enterprises (MNEs have provided substantial sponsorship for the Sochi Winter Olympic Games despite a host-country government that has recently enacted stunningly harsh legislation aimed at the Lesbian, Gay, Bisexual, Transgender, and Intersex (LGBTI communities within Russia. This is a Corporate Social Responsibility (CSR problem. Should Europe address it through voluntary corporate compliance, Europe’s historically preferred mode of promoting CSR? Or should Europe reconsider whether it can more effectively promote CSR compliance legislatively – and if so, by what kind of legislation? To honor the explicit and increased protections of human rights against sexual orientation discrimination in the Treaty of Amsterdam and the Charter of Fundamental Human Rights, more than voluntary, good intentions are needed. Particularly since the United States has effectively bowed out of enforcing CSR through the American federal courts, there now exists a regulatory lacuna that the European Commission is best situated to fill through the precision offered by judicious rulemaking. The article ultimately proposes an approach that combines the public-pressure engine that fuels voluntary CSR with public disclosures mandated by law to optimize the information and mobilization of public opinion and pressure – factors particularly noteworthy given the powerful “branding” benefits that MNEs seek through Olympic sponsorship.

Full Text Available Medical care in disabled sports is crucial both as prophylaxis and as ongoing medical intervention. The aim of this paper was to present changes in the quality of medical care over the consecutive Paralympic Games (PG. The study encompassed 31 paralympians: Turin (11, Vancouver (12, and Sochi (8 competing in cross-country skiing, alpine skiing, biathlon and snowboarding. The first, questionnaire-based, part of the study was conducted in Poland before the PG. The athletes assessed the quality of care provided by physicians, physiologists, dieticians, and physiotherapists, as well as their cooperation with the massage therapist and the psychologist. The other part of the study concerned the athletes’ health before leaving for the PG, as well as their diseases and injuries during the PG. The quality of medical care was poor before the 2006 PG, but satisfactory before the subsequent PG. Only few athletes made use of psychological support, assessing it as poor before the 2006 PG and satisfactory before the 2010 and 2014 PG. The athletes’ health condition was good during all PG. The health status of cross-country skiers was confirmed by a medical fitness certificate before all PG, while that of alpine skiers only before the 2014 PG. There were no serious diseases; training injuries precluded two athletes from participation. The quality of medical care before the PG was poor, however, became satisfactory during the actual PG. The resulting ad hoc pattern deviates from the accepted standards in medical care in disabled sports.

To assess the epidemiological risk of introduction of serious infectious diseases in the pre-Olympic period defined list of dangerous and exotic infections and held assessment of potential danger threatening. Initial external information to assess the potential risk of skidding were reports, forecasts, posted on the official websites. The risk of skidding and epidemiological complications conditionally designated as high, moderate and minimal risk importation of measles virus-Rate was considered as high. In confirmation of the forecast for the period of the Olympic Games in Sochi have been registered about 100 cases of measles. Moderate risk of importation was determined for poliomyelitis due to wild poliovirus, Lassa fever, cholera, plague, and the minimal--for Dengue fever, yellow fever, the Middle East and respiratory syndrome, diseases caused by viruses Marburg and Ebola. Based on of analysis of previous Olympic Games and subsequent co-events related to the activity of the infectious diseases in the world, mate-cluded that even a slight risk of importation of infectious diseases requires maximum alertness and readiness to conduct adequate epidemiological issues incorporated.

Sports injury and illness surveillance is the first step in injury and illness prevention, and is important for the protection of both athlete health and performance in major competitions. To identify the prevalence, severity nature and causes of athlete injuries and illnesses in the Great Britain Olympic Team (TeamGB) during the Sochi 2014 Winter Olympic Games. The observational prospective cohort study followed the Great Britain Injury/Illness Performance Project surveillance methodology and obtained information on injuries and illnesses that occurred during the Games between 30 January and 23 February 2014 in TeamGB athletes (n=56). Among the 56 TeamGB athletes, there were 27 injuries and 11 illnesses during the Olympic Games period. This equated to 39% sustaining at least one injury and 18% at least one illness, with an incidence of 48.2 injuries and 19.6 illnesses per 100 athletes, respectively. Of all injuries and illnesses, 9% and 7%, respectively, resulted in time loss. The risk of sustaining an injury was highest for freestyle skiing, skeleton and snowboarding; and lowest for curling, biathlon and Alpine skiing (with no reported injuries); with the lower limb being the most commonly injured location. Respiratory system illnesses were most frequently reported overall, and older female athletes were the ones most affected by illness. The risk of injury was double the risk of illness for TeamGB athletes. Overall, the rate of time-loss issues was low. Methodological considerations are important when interpreting data, and prevention strategies should focus on those issues causing the greatest risk, in terms of prevalence and severity, to athlete health and performance.

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)

Physical data produced by large helical device (LHD) experiments is supplied by the Kaiseki server, and registers more than 200 types of diagnostic data. Dependencies exist amongst the data; i.e., in many cases, the calculation of one data requires other data. Therefore, to obtain unregistered data, one needs to calculate not only the diagnostic data itself but also the dependent data; however, because the data is registered by different scientists, each scientist must separately calculate and register their respective data. To simplify this complicated procedure, we have developed an automatic calculation system called AutoAna. The calculation programs of AutoAna are distributed on a network, and the number of such programs can be easily increased dynamically. Our system is therefore scalable and ready for substantial increases in the size of the target data.

The historic database of tsunamis in the Black Sea contains 20 - 30 events with different level of validity, and at least six events occurred in 20th century. Numerical modeling of the last historic events is performed in the framework of shallow-water theory with use of code NAMI-DANCE. The computed tide-gauge records in Russian coastal locations are in good agreement with instrumental data for the 1939 and 1966 tsunamis. The tsunami of the landslide origin occurred in Sochi in 1970 is modeled in the framework of the two-layer model realized in TUNAMI. Also, some hypothetic tsunamis generated in the open part of the Black Sea are computed and the distribution of the tsunami height along the Russian and Turkish coast ais found. In particular, the tsunami amplification near Sochi is highest to compare with other coastal locations on the Russian coast of Black Sea.

The stability of a missile guidance system was analyzed with the Popov {prime} s hyperstability theory, considering target tracker model uncertainties. After the basic block diagram was derived as a mathematical model of the guidance system, the stability of the guidance system was analyzed as a nonlinear time-variable system, based on the Popov {prime} s hyperstability theory. Based on the results, several requirements of target tracker model uncertainties, and dynamic properties such as a natural frequency and damping characteristics of missiles, were derived for the hyperstability of the guidance system. In addition, after the hyperstable minimum range of missiles was defined, the relation was given by the use of an example between target tracker model uncertainties and the hyperstable minimum range or miss distance. As a result, the analysis allowed to derive design requirements such as dynamic properties for robust guidance systems. 12 refs., 11 figs., 2 tabs.

In driving a motor by a solar cell, if the sun light is weak, the motor cannot be started because of the fact that the start-up current of the motor is more than the current needed for driving. In this invention, a current limiting circuit is placed between the solar cell and the load, whereby the current limitation by said limiting circuit is released when the detected voltage of the solar cell reached the value required for starting the load. The current limiting circuit uses a semiconductor element such as a thyrister and a transistor which general limits a current. Such a current limiting circuit is controlled by a voltage detecting circuit and is so constructed that the cell limitation is released when a specific preset volatge of the solar cell is reached. 2 figs.

In a conventional solar power generation system having shunt elements for controlling generated power and supplying the controlled power to a load, it is difficult to carry out a stable power control, because the shunt characteristics of an analogue shunt element driving circuit vary widely as compared with a digital shunt element driving circuit, as the temperature varies. According to the present invention, in a solar power generation system having a plurality of solar cells divided into two of the first and second cell groups and a first and a second shunt element driving means provided for the first and second cell groups, the first shunt element driving means is composed of a combination of a resisance and level shift diode arranged, and the second shunt element driving means is composed of a combination of a transistor and level shift diode arranged. A stable current control of the shunt elements can be therefore realized, because the control voltage range of the first and second shunt element driving means is changed so as to be expanded, as the temperature varies, so that their overlapped voltage range is kept constant. 7 figs.

Concerning the existing solar power generating device using the analogue sequential partial shunt system, the number of interface line between the solar cell panel and the shunt dissipater is enormous and complicated in addition to the increased temperature rise of the shunt transistor in its working condition. Furthermore, concerning the digital sequential full shunt system, the above temperature rise becomes less, but the above number of interface line is likewise enormous. In order to remove the above defects, the solar power generating device which this invention concerns has the features that, in each row of solar cells connected to shunt transistors which are controlled respectively in a manner of on (saturation)/off independently in accordance with the amount of surplus electric power, the number of parallel connection of the unit cell circuits composing the each row above is made to be the different number respectively. Besides, it is proposed to have the feature in particular that such a number is made to be the number of 2 {sup n} (n is from zero to any integer, m) where n is increased by one progressively. 5 figs.

Full Text Available Content and composition of hydrocarbons (mainly the aliphatic ones in the suspended matter and the bottom sediments in the Gelendzhik Bay, the Big Sochi water area, the Feodosiya Bay and the Black Sea central part are defined and compared with the total organic carbon and chlorophyll a contents. It is shown that the aliphatic hydrocarbon concentrations exceeding the background ones are found only in the coastal zone. Advancing to the pelagic zone is accompanied by sharp decrease of their concentrations. Petroleum and pyrogenic hydrocarbons are mainly manifested in the polycyclic aromatic hydrocarbons composition. Influence of construction of the Olympic facilities upon distribution of hydrocarbons in the Big Sochi water area was of short duration, and already by 2015 the aliphatic hydrocarbons concentration decreased, on the average, up to 24 µg/l in the surface waters, and up to 18 µg/g – in the bottom sediments. Accumulation of hydrocarbons took place in bottom sediments, where their concentrations exceeded the background ones in terms of dry weight. In the Gelendzhik Bay, their content reached 252 μg/g, and in the composition of organic carbon (Corg > 1 %, which may indicate the contamination of sediments with oil products. In the Feodosiya Bay their part in the composition of Corg did not exceed 0.73 % and was 0.35 % on average. Natural alkanes dominated in the composition of aliphatic hydrocarbons. The bottom sediments are characterized by the predominance of odd high-molecular terrigenous alkanes. The content of polycyclic aromatic hydrocarbons in the studied sediments was rather low: up to 31 ng/g in the Gelendzhik Bay, up to 348 ng/g in the Feodosiya Bay. These concentrations according to the EPA classification are considered background, or minor petroleum hydrocarbons increase the level of aliphatic hydrocarbons in water and sediments, thus creating a modern hydrocarbon background.

In the conventional fuel cell heat utilization system, the waste heat is recovered to be utilized by either the waste heat recovery heat exchanger or the waste heat recovery steam. In the employment of the waste heat recovery heat exchanger system, however, the utility value is decreased when the temperature of the waste heat is lowered. Contrarily, in the employment of the waste heat recovery steam system, the supplementary water requirement is increased corresponding to the amount of waste heat recovery steam, resulting in the cost increase for water treatment. This invention solves the problem. In the invented fuel cell heat utilization system, a pressurized water from the steam separator is introduced into the second circuit to utilize directly the heat in the heat utilization system without employing the heat exchanger. If a blowdown valve is installed between the second circuit heat utilization system and the steam separator, the heat loss due to the blowdown can be reduced, since the low temperature water is blown down after being utilized in the heat utilization system. 4 figs.

Full Text Available On May 20, 1938, two American-made Chinese airplanes—Martin B-10 monoplane bombers—took off from Ningbo, Fujian province, in the direction of southwestern Japan. Instead of dropping bombs, they released propaganda materials produced by the Nationalist Party (Guomindang, pleading with the industrial workers, farmers, and petty bourgeois citizens of Japan to stop fighting China and resist their militarist government. This “humanitarian bombardment,” masterminded by Chiang Kai-shek, is little known today—perhaps deservedly so, for it had its embarrassing features. For one, the planes never reached the strategically important areas and merely flew over sparsely populated regions of Kumamoto and Miyazaki prefectures. Further, the propaganda materials were either voluntarily turned over to or confiscated by the Japanese authorities almost as soon as they hit the ground. As far as we can tell, the operation had little impact on the Japanese attitude toward China or on the Second Sino-Japanese War (1937–1945...

According to the trend of car suspensions announced in 1989, not only sports cars but also sedans have extensively applied a multi-link type and a double-wishbone type which are to improve operation stability and comfortableness by reexamining all their fundamental structures. Active suspensions with electronic control have been put to practical use and adopted for the first time to mass-produced cars such as INFINITI'' and CELICA''. Concerning steerings, most types of light cars are now equipped with power steerings. Moreover, application of air bags has increased, and safety has been improved by commercialization of the first mechanical air bags in addition to the conventional electrical ones. As for brakes, more anti-lock brakes have been used for 4WD cars and low-displacement cars. Motorcars with a traction control system have consequently increased. Thus both the anti-lock brakes and the traction control system are contributing to the improvement in safety. 17 figs., 2 tabs.

Full Text Available Studies conducted at the Subtropical Botanical Garden of Kuban (Utch-Dere, Sochi pretty much allow to explain the abnormally high drought resistance of Liriope graminifolia Lour. and Ophiopogon japonicus Ker.-Gawl., plants that naturally grow mostly in sufficient humidity. Quite low temperatures of the leaves’ surface allow to effectively condense the atmospheric moisture and to direct it along the leaf blade to the ground. The accumulation of condensation water leads to self-irrigation, a mechanism that ensures survival of plants in case of insufficient natural precipitation in the form of rain or fog. Combined with xeromorphic leaves with a thick cuticle and thick branch roots with fusiform bulb-shaped swellings, allowing to store water, makes the named plants extremely resistant to stress factors such as prolonged summer droughts accompanied by high daytime temperatures.

Studied in this paper is the use of a photovoltaic power generation system in combination with a wave energy conversion system to cover the latter`s weak point that it is available but intermittently. An offshore floating wave power device Mighty Whale (MW) is described, which will have a wave energy absorbing air chamber in the front and an anti-rocking float that looks like a whale in the rear. The movement, up and down and back and forth, of the water surface in the air chamber due to incident waves turns the power generator turbine. Out of the space available on the MW, a 200m{sup 2} area has been specified as the place suitable for the installation of solar cells capable of a maximum output of 20kW, for which specification the elevation of the sun has been taken into account. Batteries will routinely be supplied with power in parallel from the wave activated and photovoltaic devices, the supply will be limited when the batteries are fully charged, and an auxiliary power generator will be run in case of shortage. Power that can be provided by a 20kW solar array was calculated using actual data of sunshine on the slope for each array orientation, and required battery capacity was calculated for each solar array orientation. Important items for consideration for the insurance of reliability on the ocean include measures against salt damage, detailed designing of wiring, and coordinated operation of photovoltaic and wave activated power generation systems. 3 refs., 6 figs., 5 tabs.

This paper introduces features and trends of analyzing performance and construction of automotive tires. Tires are demanded of high durability, high motion performance, good comfort performance for vibration and noise, and low fuel consumption performance. A feature of analyzing the construction is to execute a modelling assuming that a tire has air-rigid flexible structure and rubber materials show hyperelastic behavior, hypothesizing a strain energy density function. In addition, a tire is highly incompressible. Visco elasticity and anti-friction performance are also important points. Rubber and cord layers have elastic characteristic of three-dimensional perpendicular anisotropy as well as non-linearity with which characteristics change according to transformation. A structural analysis must cover from static analysis to steady dynamic analysis, non-steady dynamic analysis, and eigenvalue analysis. Thermal analysis of tires simulates phenomena by combining dynamical analysis with thermal analysis. Super-computers have now come to be used for formulating equilibrium equations using finite element methods, developing finite elements, and performing heat or visco elasticity analysis and applied analysis. 35 refs., 3 figs.

Full Text Available Commemorative coins are one of the attributes of the modern Olympic movement, relating to the category of «Games Product». Monetary program “Sochi 2014”, realized since 2011 is one of the most extensive and design diversified. The tradition to stamp out coins in the host city of the Olympic Games was established in Ancient Greece. They served not only as a means of exchange or as a store of value, ancient Greeks managed to make them works of art. Ancient authors’ data, concerning coinage site, time and type don’t give an accurate account of the coins we can reasonably call the “Olympic” ones. This problem has been solved by numismatologists from late XVIII century through the present. Their views of ancient “monetary program” differ. This article is focused on the special character of these discrepancies both in historical records and historiography

This paper describes the creep analysis and torsional vibration analysis of cable-stayed bridges with two edge composite girders. The girder is composed of the concrete slab and the steel girder. I-girders are placed at both edges of the profile. Such a type of bridge was investigated. As the stress migrates by the creep of concrete slab, it is necessary to evaluate the influence of this creep precisely in designing. In the analysis, the composite girder was expressed not by the single member, but by the binary member consisting of concrete member and steel member. Two methods were employed, i.e., method A in which both members are connected by the rigid body beam and method B in which the profile of concrete is converted into the profile of steel. The method A provided better accuracy, but the method B was often sufficient. Torsional rigidity of the open profile structure was much smaller than that of the box profile. As the torsional natural frequency was low, proper torsional vibration analysis was indispensable especially from the viewpoint of wind resistance. Two methods were employed, which utilize the vibration analysis method for general space frame structures. Results of both methods were agreed mutually, but the second method provided better calculation efficiency. 10 refs., 9 figs., 6 tabs.

This paper presents a model of the artificial ice track in Whistler, Canada that is based on its construction data, and a model of a two-men bobsleigh consisting of nine rigid bodies, having 13 degrees of freedom and incorporating 17 hard frictional contacts. These models are implemented within a simulator that is capable of performing accurate real time simulations of piloted runs on commonly available PC hardware. The simulation is verified against the results of the official two-men race that took place during the Olympic Winter Games in 2010.

This paper presents a model of the artificial ice track in Whistler, Canada that is based on its construction data, and a model of a two-men bobsleigh consisting of nine rigid bodies, having 13 degrees of freedom and incorporating 17 hard frictional contacts. These models are implemented within a simulator that is capable of performing accurate real time simulations of piloted runs on commonly available PC hardware. The simulation is verified against the results of the official two-men race that took place during the Olympic Winter Games in 2010. The simulator has been used by several professional Swiss pilots during their preparation for the 2014 Olympic Winter Games in Sochi, Russia. The simulator is exploited to analyse and judge the range of possible driving lines regarding speed and runtime improvements. It could also serve to consult track designers about safety issues and sleigh constructors about the expected dynamics on a track.

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.

Fuji Electric Co., Ltd., is advancing its research and development efforts for cold crucible levitation melting (CCLM) equipment in which metal is caused to be levitated in the air and is melted. Such a unit consists of a water-cooled copper crucible, a water-cooled coil installed to surround the crucible, and a high-frequency power source. Eddy currents are induced in the crucible and metal upon application of a high-frequency current to the coil, and electromagnetic repulsion is generated between the eddy currents. When the force of repulsion is greater than the force of gravity acting on the metal, the metal leaves the crucible to be levitated in the air. At the same time, the metal is heated by the Joule heat produced by the eddy currents, and is melted. So far, for the stabilized levitation melting of a kilogram-level amount of metal, a double power source excitation system has been adopted and the crucible bottom configuration has been optimized. Also, non-contact tapping of molten metal from the bottom and increase of the molten metal amount to the 50 kilogram level have been achieved, these for the industrialization of the technology. Already available on the market are equipment for large-capacity CCLM, continuous casting CCLM, and the high-vacuum CCLM. 5 refs., 13 figs., 3 tabs.

This paper describes development and operation evaluation on a domestic plant cultivating unit that can cultivate plants throughout a year by installing a prototype cultivating device effectively utilizing electric power, and controlling the cultivation environments. The prototype plant cultivating device uses trially an air cooling heat pump for general household use with high general-purpose applicability installed in a glass greenhouse with an area of about 10 m[sup 2], similar to those used by orchid lover club members. The device also uses commercially available humidifying and ventilating devices. No household horticultural facilities in cold district have ever used this kind of heat pump. Generally, cultivating environments in glass greenhouses are affected more easily by outside climate change as the greenhouse volume becomes smaller. For this reason, with this small-scale prototype cultivating device, orchids are cultivated to identify cultivating environments, and study technological development on controls over proper year-round cultivation and effective cultivation environments, as well as development and operation evaluation on household plant cultivation devices. 2 figs., 1 tab.

The recycling business about glass bottles having extended widely, ratio of recycled materials has come up to 55% out of all raw materials for bottle manufacturing. For the purpose of effective reuse, sorting by color into colorless, brown, green, etc. is indispensable. But, at present, this sorting work relies solely upon manpower. In response to the demand for automation of the above work, automatic color sorting system has been developed. In the first place, a pre-sorter can divide bottles into large ones (larger than 10cm in diameter), small ones and cullets. Bottles from the pre-sorter are arranged horizontally on a conveyer, and then light is shined in the direction from each bottle neck. By a color camera, each light permeated through a bottle bottom is caught. Next, by means of an image processing unit, bottles are gathered by color. Cullets are put on several conveyers and are separated by means of color sensors and air nozzles. Disposing capacity of one unit is 5,000 bottles/hr by each size, and one ton of cullets/hr. 4 figs., 2 tabs.

Nowadays there is an obvious grow of anthropogenic load going on in many areas worldwide. Under such conditions, intensive activation of a number of exogenic geomorphic processes may be observed. Moreover, if natural environment is aggressive itself their dynamics and rates may reach enormous values. Our work is conducted at the Black Sea coast, known for its mountainous topography, wet subtropical climate and intensive anthropogenic development (especially during the last decade due to the recent Olympic games). We chose two key basins near Sochi, Russia to study a number of presented exogenic processes, including rill, gully and channel erosion, weathering, suffusion and piping, soil creep. A set of field study methods is used to monitor the processes dynamics since 2005 (and late 1970s for soil creep). In addition, soil erosion rates and landslide susceptibility were modelled to get information of the watersheds dynamics. This is ongoing work, but the results of the passed period of observations will be resented. Special attention is paid to the processes connectivity and their input into sediment redistribution over the river basins.

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

Uninterruptible power systems (UPSs) are widely used in financial institutions, utility services, totalizator systems, traffic control systems, plants, new media, medical systems, and information processing services. These are highly reliable power supply systems to protect computer-aided information and communication systems from power failure or defects. Described herein is the company`s line of UPSs developed by integrating power electronics, and digital and high-frequency switching techniques. The major components of a UPS are rectifier, inverter and battery. Power is supplied by commercial or inverter system. The former is widely used by plants because of its low loss and high efficiency, although distorted output waves or instantaneous power failure may occur when the power source is switched in the case of power failure. The latter is suited for computer systems, because of its ability of stably supplying power, without being affected by the disturbances which may occur in the commercial system. 7 figs., 2 tabs.

A program has been developed to conduct inversion analysis of two-dimensional model using MT data, accurately. For the developed program, finite element method (FEM) was applied to the section of sequential analysis. A method in which Jacobian matrix is calculated only one first time and is inversely analyzed by fixing this during the repetition, and a method in which Jacobian matrix is corrected at each repetition of inversion analysis, were compared mutually. As a result of the numerical simulation, it was revealed that the Jacobian correction method provided more stable convergence for the simple 2D model, and that the calculation time is almost same as that of the Jacobian fixation method. To confirm the applicability of this program to actually measured data, results obtained from this program were compared with those from the Schlumberger method analysis by using MT data obtained in the Hatchobara geothermal area. Consequently, it was demonstrated that the both are well coincided mutually. 17 refs., 7 figs.

Neural network is used for the prediction of porosity and permeability using logging data as reservoir characteristics, and the validity of this method is verified. For the prediction of reservoir characteristics by the use of seismic survey data, composite seismic survey records obtained by density logging and acoustic logging are used to experiment the prediction of porosity and permeability continuous along lines of wells. A 3-output back propagation network is used for analysis. There is a possibility that this technique when optimized will improve on prediction accuracy. Furthermore, in the case of characteristics mapping, 3-dimensional seismic data is applied to a carbonate rock reservoir for predicting spatial porosity and permeability. This technique facilitates the comprehensive analysis of core data, well data, and seismic survey data, enabling the derivation of a high-precision spatial distribution of reservoir characteristics. Efforts will continue for further improvement on prediction accuracy. 6 refs., 7 figs., 3 tabs.

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

As a supplementary type semiconductor device has a complicated structure, it is extremely difficult to construct it in a three dimensional structure. This invention aims to reduce its occupying area by forming p-channel and n-channel transistors in a solid structure; moreover in an easy method of production. In other words, an opening is made in the element-forming region of a semiconductor substrate, forming a gate-insulation film on each of the p-type and n-type semiconductors which are exposed on the two facing surfaces; on it formed a gate electrode; p-type semiconductor surface is used as a channel domain; a drain region of n-channel transistor on one surface and a source region on another surface; the n-type semiconductor surface corresponding to the gate electrode is used as a channel region; a source region of the n-channel transistor is formed on the same surface and the drain region on the substrate surface. Occupied area is thus made less and the production gets easier. 20 figs.

Fullerene (C60) and carbon nanotubes are expected as new carbon structures. This article describes the observation results of C60 and carbon nanotubes by means of STM (scanning tunnel microscope). The STM images of C60 thin films are illustrated, which have been obtained by annealing at 290 centigrade. It was confirmed that C60 monomolecular thin films are formed which conform to the substrate and have high regularity. The step height of C60 monomolecular thin films coincided with the step height of Cu (111) plane, which suggested that the step of films is reflected in that of Cu substrate. For the STM images under bias voltages, various images of C60 with three-fold axis of symmetry were observed. On the other hand, from STM observation of carbon nanotubes with diameter of about 30 nm which were separated and purified from the cathode deposits during the preparation process of C60, it was found that they have concentric multilayer structure. 18 refs., 7 figs.

Efforts were made to enhance analytical precision and stabilize the results in seismic traveltime tomography by use of a method wherein the velocity distribution is expressed as a continuous function interpolated by parameters respectively assigned to the gridpoints. In this method, the slowness data are regarded as the parameters respectively assigned to the gridpoints, and the slowness value at a given point is determined after interpolation by the gridpoints surrounding the said point. A method based on the variation principle was used for ray tracing. As the result, it was confirmed that this method determines the ray path and traveltime with high precision. A method of least squares using Lagrange`s multiplier was applied for inversion. Comparison was made between the use of cells and the use of gridpoints in the results of inversions performed for an inclined 4-layer structure model, when it was found that the values involving the boundaries between layers, inclinations of the layers, and velocities of seismic waves are ambiguous with the cells while those with the gridpoints are reconstructed roughly correctly. 5 refs., 7 figs., 1 tab.

A large outbreak of hemorrhagic fever with renal syndrome (HFRS) occurred in the winter of 2006-2007 in a region southeast of Moscow in Central European Russia. Of the 422 patients with HFRS investigated in this study, 58 patients were found to be infected by Puumala virus, whereas as many as 364 were infected by Dobrava-Belgrade virus (DOBV). Early serum samples from 10 DOBV-infected patients were used for nucleic acid amplification, which was successful for 5 patients. Molecular analyses demonstrated that the causative hantavirus belongs to the DOBV-Aa genetic lineage, which is carried by the striped field mouse (Apodemus agrarius) as the natural reservoir host. Neutralization assays with convalescent-phase sera from these patients confirmed infection by DOBV-Aa; related viruses, such as the Dobrava-Slovenia virus (DOBV-Af) and the Dobrava-Sochi virus (DOBV-Ap), were neutralized at lower efficiencies. The clinical courses of the 205 patients enrolled in the study were found to be mostly mild to moderate; however, an unexpectedly high fraction (27%) of patients exhibited severe illness. One patient died from kidney failure and showed symptoms of generalized subcutaneous hemorrhage. The results provide molecular, serodiagnostic, and clinical evidence that DOBV-Aa is a common pathogen in East Europe that causes large outbreaks of HFRS. PMID:19828747

Full Text Available The article on the basis of archival documents examines the role of teaching staff of educational institutions of the Black Sea province during the First Russian revolution. The attention is paid to the participation of students of senior classes in the revolutionary movement. Among the materials are the archival documents of central and regional archives, namely the state archive of the Russian Federation, Russian state military historical archive, the state archive of the Krasnodar Krai, the center for documentation of contemporary history of Krasnodar Krai and the archive department of historical museum of city-resort Sochi. The authors come to the conclusion that on the territory of the Black Sea province, the activities of significant part of the teaching staff were aimed at destabilization of the political situation, contributing to the overthrow of the existing government. Rather than to protect the high schools students from the influence of political propaganda and to return students to the classrooms, some teachers have contributed to reverse the process, encouraging the study of the political programs of the parties and the desire to participate in the revolutionary movement. As a result, the schoolchildren, minors with unsettled teenage psychology participated in various revolutionary actions, which could lead to the tragic consequences.

Described herein are the results of the FY1994 research program for analysis and evaluation for thin-film compound semiconductor solar cells. The study on epitaxial growth and optical properties of the thin films of CuInSe2 and CuGaSe2 evaluates the thin epitaxial films grown under various conditions, showing morphology of the defects at the interface of heteroepitaxial growth. These results are used to set the growth conditions under which a thin film of high luminescence by exciter recombination is produced. The study also gives information of luminescence transition in the vicinity of the band ends and of energy level between the bands. The study on structural analysis of the epitaxially grown thin films of CuInSe2 investigates dependence of lattice constants of the MBE-grown CIS layer on film thickness by the X-ray diffractometry based on the bond method. The study on epitaxial growth by the Se(CH3)2-halogen transfer method tests epitaxial growth of the single-crystalline Mo on a substrate of single-crystalline sapphire. 5 figs.

In order to measure sound absorption performance necessary to develop sound absorption materials, development was made on a device consisting of a small sound box capable of measurement inexpensively and easily, as a measure against the reverberation chamber method. In order to obtain stabilized diffusion sound internally, the sound box has a shape of asymmetric seven-side body in which sides do not face squarely with each other. The box was so sized that a large number of resonant vibration postures can be constituted at the targeted frequency simultaneously in the box. The box has a commercially available cone speaker with good acoustic output characteristics in frequency range of higher than 500 Hz installed on an inner side of the box. The sound source uses a method to derive sound absorption rate from difference of sound pressure levels. In order to eliminate need of averaging treatment by using a multi-point measurement inside the box, a discussion was given to provide an opening on part of the box to place the sound receiving point outside the opening. A square test piece is placed on the floor 0.5 meter or more away from the speaker in the box. As a result of the experiment, it was verified that the sound absorption rate obtained by this device corresponds well with that by the reverberation chamber method. The size of the test piece was also found adequate. 2 refs., 11 figs., 1 tab.

In an indirect internal reforming type molten carbonate fuel cell, the reforming temperature is limited less than the operating temperature of the fuel cell, as the heat source for reforming is depended on the reaction heat at about 650 {degree} C of the fuel cell. To improve the reforming rate at the low temperature range, it is considered to increase S/C (ratio of steam to carbon), but this scheme will cause such problems as to increase the voltage drop of the anode, to drop the heat recovery ratio on the cogenerator, to increase the capacity of the heat exchanger, etc. In this invention, in the power generating plant of a molten carbonate fuel cell the inert gas is added to the reforming raw gas, and in addition to the above the gas is mixed with steam and led into the reforming chamber of the plant. When the inert gas which is not directly concerned in the reforming reaction is added to, total mol number increases and the reforming reaction is acceralated. Consequently, the reforming rate can be raised, though the reforming temperature is low. 2 figs.

Numerical analysis of impact response was carried out when a bird strike was simulated to study the applicability of fiber reinforced composite material to fan blades for turbo-fan engines. The validity of the numerical analysis was verified by comparing the analyzed results with impact tested results of a fan-blade model of Ti-alloy. The impact resistance was studied by applying this method to fan blades of composite materials such as carbon fiber, epoxy resin and carbon-silicate fiber reinforced Ti-alloy. The finite element method was used for the analysis by dividing the model into triangular flat elements. The relation between the impact load, the deformation of blade and the strain, the natural frequency characteristics, the elastic modulus and hetrogeneity of blade were considered to analyze the impact response. The impact load by the strike of 1.5 lbs bird is very severe to the fan blades for turbo-fan engines having the thrust of 5 ton class. 23 refs., 23 figs., 3 tabs.

An imbalanced current distribution is often observed in cable-in-conduit (CIC) superconductors, which are composed of multistaged, triplet type sub-cables, and deteriorates the performance of the coils. Therefore, it is very important to analyze the current distribution in a superconductor and find out methods to obtain a homogeneous current distribution in the conductor. We apply a magnetic flux conservation in a loop contoured by electric center lines of filaments in two arbitrary strands located on adjacent layers in a coaxial multilayer superconductor, and then analyze the current distribution in the conductor. A generalized formula governing the current distribution can be described as explicit functions of the superconductor construction parameters, such as twist pitch, twist direction and radius of each layer. It is shown that we can obtain a homogeneous current distribution using this fundamental formula, which is a function of the twist pitches of layers. Moreover, it is demonstrated that we can control current distribution in the coaxial superconductor. (author)

In the design of a large-scale flywheel. load capacity and bearing constants (i.e. spring and damping constants) should be accurately calculated. In this report, a newly developed analysis method for radial-type superconducting magnetic bearings (SMBs) composed of several couples of magnet rings and magnetic material spacers is described. The analysis based both on electromagnetic FEM of the magnetic field and the 2-dimensional Bean model for analysis of the magnetization of type-2 superconductors. To obtain accurate magnetization hysteresis that reflects the complex magnetic fields, a superconductor is meshed into cells and then the electromagnetic force between the magnetic fields of magnetics and the magnetization of the superconductor are calculated. Recently, computer programs which can calculate the axial load capacity of radial-type SMBs have been developed. Furthermore, programs which can calculate bearing constants are close to being completed. Calculated results on axial load capacity showed good agreement with the experimental results. (author)

An automatic measurement system by means of conductive potential and self-potential methods (fluid flow tomography method) has been developed to measure the change of geothermal steam fluid during production and injection. For the fluid flow tomography method, the four-electrode configuration of the conductive potential method is adopted using the casing pipe of well as a current source. A lot of potential receiving electrodes are connected to the earth, preliminarily. The surface potential profile is measured, which is formed during the injection and production of the fluid through the well. Artificial and spontaneous potential profiles were continuously measured using this system during the hydraulic crushing tests at the test field of hot dry rock power generation at Ogachi-machi, Akita Prefecture. As a result of inversion analysis of self-potential data using a four-layer structural model of specific resistance, it was observed that the fluid injected at the depth of 711 m in the borehole permeated into the depth between 700 and 770 m in the south-eastern part of the well, and that the fractures propagated into the deeper part, gradually with the progress of hydraulic crushing test. 3 figs.

Full Text Available The general culture of design, planning and implementation of megaprojects in Russia is underdeveloped. Commercialization of procedures of projects’ justification and the involvement of expert community hinder an objective assessment of risks and efficiency of investment projects, while the aspiration to save money at stages of scientific justifications and skilled and experimental checks, lead often to adventurous decisions and unpredictable consequences. The article’s purpose is to reveal the identification signs of modern territorial megaprojects as important tool of the state strategic management and to reveal a complex of the various risks accompanying processes of development and implementation of large investment projects. The special attention is paid to such types of risk as competence and corruption risks. On the example of modern Russian megaprojects, such as “the Ural Industrial – the Ural Polar”, construction of Olympic objects in the city of Sochi, the authors show that these risks became either the reason of megaproject’s rebranding, or led to essential excess of the actual expenses in comparison with the planned. The authors are sure that identification of possible corruption risks at a predesign stage, accounting of reputation risks, elimination of low competences risks are an important task aimed at decrease of uncertainty of final effect from implementation of the territorial complex megaproject.

Full Text Available The painted polished red-clay ceramic items of the 8th-10th centuries, found on the Anakopia and other sites of Northern Abkhazia and the adjoining district of the city of Sochi are considered in the article. These are small and medium sized single-handled narrow-necked jugs. The painting is made in dark brown paint. The ornament consists mainly of straight and wavy lines; hatching in the form of oblique grids, braids and patterns of specks occur. Taking into account the new finds made during the 2007-2008 excavations of the necropolis on the Sakharnaya Golovka Mountain and of the church near Veseloye village, the analysis of painted polished ware of the Abkhazian Kingdom epoch makes it possible to determine its territorial and chronological distribution limits. The area of this pottery covers the Black Sea coast from the mouth of the Mzymta river to New Athos. Based on the results of the 1950-1980s excavations, it has been dated to the 8th-10th centuries; however, the new materials allow restricting the interval to the 9th-10th centuries. The differences in the vessels manufacturing technology indicate the presence of at least two production centers. The small painted burnished jars discovered in Christian graves suggest that they had been used to store incense or chrism.

Development has been made on element technologies for an esophageal vocalization aid system. With regard to the speaker, selection and trial production were performed on a speaker used for a phono-coupler to be used in coupling with a telephone transmitter. Performance not differing from that in the currently used telephone set was obtained in the overall characteristics evaluation using a dummy telephone circuitry. For the microphone, two kinds of hands-free microphones were fabricated on a trial basis. In order to develop pitch extraction and amplitude pitch conversion systems, pitch extraction performances were compared and discussed on the following five methods: the auto-correlation method, the Cepstram method, the average magnitude difference function (AMDF) method, the simplified inverse filter tracking (SIFT) method, and the time-domain excitation extractor using minimum perturbation operator (TEMPO) method. The hauling phenomenon, having come up as a problem in an auxiliary digital device, was analyzed to discuss methods for prevention thereof. In developing a voice/unvoiced distinction judgment method, a method using low domain power and high domain power was discussed. Development has been made on exclusive ICs, a voice analyzer, and the using feeling enhancing technology. In developing a total system, a digital unit incorporated esophageal vocalization aid system was developed and improved. (NEDO)

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

Power generation characteristics are investigated using data collected in photovoltaic power generation field tests being undertaken by NEDO (New Energy and Industrial Technology Development Organization). The photovoltaic power generation system performance is evaluated by examining loss factors leading to degradation in system performance, with weather conditions such as variation in insolation and air temperature, inverter performance, and shadows cast by surrounding buildings taken into consideration. As the result, it is found that the important loss factors are degradation in module performance due to elevated temperature, drift in the maximum output control, degraded inverter performance due to input power variation, effect of shadows, etc. It is learned that system is greatly affected by degradation in module performance due to increased temperature in summer and by shadows in winter, the two being responsible for the output coefficient dropping to approximately 75% throughout the year. The output coefficient frequency distribution charts for the 75 test sites confirm that the rate is as low as 70-80% at many sites. As for the system operating time, it tends to be longer in West Japan where the annual insolation rate is higher. 3 refs., 10 figs.

By applying computational fluid dynamics (CFD) to a flow in the supersonic air intake of rocket, appropriateness of computational result was confirmed from a comparison with the wind tunnel test result. In order for the air intake type rocket to heighten the combustion efficiency of fuel and air, it is important to possibly minimize the total pressure loss of air which has been taken in and maintain the air flow rate. A numerical analysis was made through modeling the sectional shape of wind tunnel test body and analyzing the two-dimensional flow by Reynolds-averaged Navier-Stokes equations. The computational result of analysis coincided well with the pressure measurement result in wind tunnel test. Having elucidated the main factors of total pressure loss in a two-dimensionally curved flow passage, the CFD computation gave a possibility that the total pressure loss is considerably low against that passage if improved in shape. If simultaneously used with a characteristic curve method, the CFD computation made it possible to optimize the pressure recovery characteristics in the axially symmetric air intake. The CFD can be expected to be an effective method of designing the basic shape of supersonic air intake. 9 refs., 14 figs.

Liquefied petroleum gas (LPG) is a very important fuel and chemical feed stock as well; however, the hydrocarbon has been involved in many major fires and explosions. One of these accidents is boiling-liquid, expanding-vapor explosion (BLEVE). It is a phenomenon that results from the sudden release from confinement of a liquid at a temperature above its atmospheric-pressure boiling point. The sudden decrease in pressure results in the explosive vaporization of a fraction of the liquid and a cloud of vapor and mist with the accompanying blast effects. Most BLEVEs involve flammable liquids, and most BLEVE releases are ignited by a surrounding fire and result in a fireball. The primary objective of this paper is to develop a computer model in order to determine the thermal response of a spherical LPG tank involved in fire engulfment accidents. The assessment of the safety spacing between tanks was also discussed. (author)

The research method heat transfer process by physical change of the coke by heat transfer from furnace wall in the retorting of coal seam filled in coke oven and flow of the gas is very complicated chamber oven style, and it does not become clear. For the purpose of the elucidation of in layer crack generation and progress mechanism, he is (1) The expansion of the softening cohesive layer. (2) Programming rate dependence of the heat. Mechanical property value on coal seam and semi- coke layer in the retorting. (3) The creep property of softening cohesive layer and semi- coke layer. (4) The setting of crack growth condition of stress intensity factor in crack tip and fracture property value of the coke by the comparison. (5) By considering the radiative heat transfer in the crack, coke in layer thermal stress analysis was carried out. The validity of these analytical result it was confirmed by the comparison with the experimental result of crack growth. Deformation behavior in the small dry distillation furnace, and crack growth mechanism in the coke layer became clear, and the prediction of the stress as micro-crack cause of generation of heating surface side coke surface and inside became possible. The numerical analysis method of the above crack growth mechanism greatly contributes to the prediction of dry distillation heating requirement and grain size of coke lump which is an index to the coke quality. Heat on material process which is accompanied by the solidification. Contraction from the softening and material migration phenomenon have been clarified by the creative research method, while this research is directly useful for energy saving of pig ironmaking process of becoming one of the ringleaders of the CO{sub 2} generation.

The magnetic structure in Hokkaido was quantitatively analyzed by the magnetic anomaly distribution. This paper describes its characteristics. Detection of structural boundaries and 3-D analysis of double-layer structure were conducted for the regional magnetic data in a region with about 500 km square. There was not so large difference in patterns of magnetic anomaly distribution between the case that the direction of magnetization was set at 45{degree} to the west during the geomagnetic conversion according to Segawa and Oshima and the case that it was set as same as the current geomagnetic direction. The method of Blakely and Simpson was useful to detect the boundaries of magnetic structures. The structural boundaries obtained were more linear than the iso-magnetic contour lines. A new method has been conceived in which the approximation of 3-D magnetic structure analysis can be deduced, and the irregularity of magnetic basement can be determined by the repeated calculation. In practice, this method was applied to the magnetic data in the whole Hokkaido. The calculation was stably converged. It was found that the magnetic structure obtained in the Kamuikotan/Ishikari-Kitakami magnetic belt exhibited a fault structure having steep slopes accompanied by the basin structure in the western boundaries. 19 refs., 6 figs.

Large deformation of the crust is generated by relatively large displacement of the mediums on both sides along a fault. In the conventional finite element method, faults are dealt with by special elements which are called joint elements, but joint elements, elements microscopic in width, generate numerical instability if large shear displacement is given. Therefore, by introducing the master slave (MO) method used for contact analysis in the metal processing field, developed was a large deformation simulator for analyzing diastrophism including large displacement along the fault. Analysis examples were shown in case the upper basement and lower basement were relatively dislocated with the fault as a boundary. The bottom surface and right end boundary of the lower basement are fixed boundaries. The left end boundary of the lower basement is fixed, and to the left end boundary of the upper basement, the horizontal speed, 3{times}10{sup -7}m/s, was given. In accordance with the horizontal movement of the upper basement, the boundary surface largely deformed. Stress is almost at right angles at the boundary surface. As to the analysis of faults by the MO method, it has been used for a single simple fault, but should be spread to lots of faults in the future. 13 refs., 2 figs.

In order to apply FEM (finite element method) flow analysis to environmental engineering, the two-dimensional analysis system was developed, and applied to the design of plant ventilation and improvement of an enviromental control equipment. Furthermore, the three-dimensional analysis system was developed to extend its application. Since in a large scale model, no enhancement of a processing capacity was expected even by a supercomputer because of longer I/O times between internal and external memories caused by a small internal memory space, the parallel processing system with multiple external memories was introduced to analyze such models. To achieve more efficient processing, multiple series of renumbering codes were also prepared to optimize the processing order of solvers, elements and nodes. As examples, the improvement of a thermal oxidizer and the ventilation design for a forging plant, and as an example of a three-dimensional large scale model, the flow analysis around a plant were presented. 8 refs., 17 figs., 1 tab.

To reduce the manufacturing cost of semiconductors, some systems have been proposed that use a cheap and high purity Clean Dry Air (CDA). CDA can reduce process step such as wafer cleaning, because CDA flow in stocker prevents the wafer surface from adsorbing of moisture and organic impurities. We have already optimized a two-stage rotary dehumidifier and have conducted a study of methods for cheaply manufacturing air that has a low dew-point of -70 degree C to -50 degree C. We have further developed the method in which a dry dehumidifier is used, and developed an ultra low dew-point air generator. The air generator is a three-stage rotary dehumidifier in which a further stage is added to the two-stage rotary dehumidifier. The main component of the rotors is metal silicate. The air generator can supply dry air with a dew-point of -110 degree C. or less, in which the concentration in all gaseous contaminants is far below 1 ppb. We made a trial calculation of the manufacturing cost, and an average cost of 0.25 yen/m{sup 3} was obtained. (author)

This paper introduces new electric power storage equipment called an energy capacitor system. A special electrically double-layered capacitor with its energy density raised in sacrifice of internal resistance has the current so adjusted that loss will not increase by using a switching converter (consisting of a charger and a current pump). The capacitor is charged and discharged at high efficiency. Upper limits of the charge voltage for each capacitor are connected with parallel monitor circuits so that maximum charge voltage of each capacitor will be aligned at one level, wherein charge and discharge are performed with that voltage used as the starting point. A drawback in a capacitor is lower energy density than in a secondary battery. Therefore, high voltage withstanding organic electrolyte was used, and electrode activated carbon was given discussions starting from its raw material structures. The efforts resulted in obtaining as high energy density as 43 Wh/kg (about 20 times as much as in conventional materials, and comparable to lead-acid batteries). In order to minimize heat generation due to the increased internal resistance, a switching converter was used to suppress charge/discharge currents to the minimum required levels. Although the capacitor still has insufficient voltage withstanding power and short life, the energy density is increasing beyond the initial estimation. The next problem to be solved is reduction in production cost for its industrialization. 4 refs., 4 figs., 2 tabs.

This invention relates to provision of a photocatalytic film on the light intercepting surface for the solar cell substrate of the solar cell element, which transmits the lights in the wavelength region longer than ultraviolet, i.e. 410nm and longer wavelength lights, and intercepts the lights in ultraviolet wavelength region. This photocatalytic film retards the decrease in the light interception by the solar cell element, and simplifies the maintenance because it oxidizes and decomposes organic matters by the less than 410nm ultraviolet ray contained in the sunlight to prevent adhesion of organic substance on the light intercepting surface of the solar cell element. In addition, decomposed dirt composition is washed away to accelerate dirt removing performance by rain waterdrop adhesion on the intercepting surface when it is used outdoors. As to this photocatalytic film, the thickness from 0.01 to 0.5{mu}m is desirable, effective phtocatalytic activity can not be expected if the thickness is less than 0.01{mu}m, and transmission factor becomes smaller if the thickness exceeds 0.5{mu}m, producing no electromotive force. TiO2, ZnO, and FeTiO3 are used as such photocatalyst. 6 figs.

The new biological deodorization device was developed using dried activated sludge as deodorant. Activated sludge obtained from a waste water treatment plant was dried at room temperature to protect from extinction of microorganisms in it before its charge into the device, and washed by water only as required. Offensive odor substances were oxidation-decomposed by microorganism after their adsorption into sludge surfaces, while microorganisms survived for a long time while getting such substances as nutritive sources. As basic deodorization characteristics were studied with the experimental device and artificial odor gases, more than 99% of 200 and 2,000 ppm H2S were removed at space velocities of 400/h and 33/h, respectively, together with nine typical offensive odor substances. As the result of demonstration tests with the small test device installed in a public waste water treatment plant, a high deodorizing efficiency was retained for 10 months or more, and its running cost was as low as 75% of that of current systems because of only one necessary washing every month. 3 refs., 14 figs., 12 tabs.

Once again, the Olympic spirit—as defined and espoused by the International Olympic Committee—will clash with the political interests that overshadow the Games. This paper examines the political undertones of the 1980 Summer Olympics, hosted by Moscow and which took place during an ice-cold period of the Cold War, and asks whether similar undertones will be on display next year. The 1980 Games were a phenomenal success for Soviet athletes and their Eastern European colleagues. However, in the absence of the United States and more than 50 other nations, the political frame from a Western context was that of athletes from a corrupt system competing alongside their comrades. The boycott of these Games demonstrated the power of the White House and the often lapdog quality of the American media. Now as the Games return to Russia, the issue of whether a Cold War-like mentality will influence U.S. media reporting of the 2014 Sochi Olympics must be asked. The conflicting images in Western news media discourse of Russian president Vladimir Putin and his “Communist past” combined with a tepid diplomatic relationship between his government and the Obama administration provide evidence that a negative portrayal of Russia and therefore its athletes will be displayed in February 2014. And yet there is no impetus for a boycott next year. This paper explores why.

Almost half of the record 98 events being held at the 2014 Sochi Winter Olympic Games were either not held 20 years ago at Lillehammer or have been substantially modified. The Olympics as a global sports event are not stationary but must adapt and evolve in response to changing demands, just as the remarkable athletes who are competing do. While the Winter Olympics program has steadily grown since Chamonix in 1924, the rate of development has greatly accelerated in the last 20 years. Three factors seem to be instrumental. First, the Winter Olympics program has become more gender balanced. Female hockey teams are battling for gold, and this year women will compete in ski jumping for the first time. Most Winter Olympics sports have equal numbers of events for men and women today, although female participation still lags somewhat behind. Second, many traditional events have been modified by sport-governing bodies toward a more "TV friendly" format. Time-trial starts have been replaced by mass or group starts. "Sprint" and team events have been added to spice up traditional sports like cross-country skiing and speed skating. Finally "extreme" sports like half-pipe and ski-cross have crossed over from the X Games to the Olympics, with some arguing that the Olympics need these popular sports more than the X Games sports need the Olympics. All of these changes create new research questions for sport scientists who are also willing to adapt and evolve.

A reappraisal of success factors for Olympic cross-country skiing.

Cross-country (XC) skiing has been an Olympic event since the first Winter Games in Chamonix, France, in 1924. Due to more effective training and tremendous improvements in equipment and track preparation, the speed of Olympic XC-ski races has increased more than that of any other Olympic endurance sport. Moreover, pursuit, mass-start, and sprint races have been introduced. Indeed, 10 of the 12 current Olympic competitions in XC skiing involve mass starts, in which tactics play a major role and the outcome is often decided in the final sprint. Accordingly, reappraisal of the success factors for performance in this context is required. The very high aerobic capacity (VO2max) of many of today's world-class skiers is similar that of their predecessors. At the same time, the new events provide more opportunities to profit from anaerobic capacity, upper-body power, high-speed techniques, and "tactical flexibility." The wide range of speeds and slopes involved in XC skiing requires skiers to continuously alternate between and adapt different subtechniques during a race. This technical complexity places a premium on efficiency. The relative amounts of endurance training performed at different levels of intensity have remained essentially constant during the past 4 decades. However, in preparation for the Sochi Olympics in 2014, XC skiers are performing more endurance training on roller skis on competition-specific terrain, placing greater focus on upper-body power and more systematically performing strength training and skiing at high speeds than previously.

Full Text Available Zheltozems (literally "yellow earths" that can be classified as Acrisols, Alisols, or Ultisols, occupy very small areas in Russia; they are strongly modified by human activities. The unchanged profiles are preserved only locally, in particular, in the Sochi arboretum. When compiling the soil map of the arboretum, different Zheltozems were described on gentle and moderately steep slopes and diverse parent materials: calcareous claystone and its heavy-textured derivates. The micromorphology of three characteristic Zheltozem profiles developed on these different parent materials was also studied. The features that they have in common are the following: in all profiles, a specific heavy-textured Bw, or BM 'metamorphic' horizon was identified with a certain set of micromorphological properties: a massive microstructure with fine planes merging into deformed biogenic pores, a monic groundmass with few silt grains that are sometimes oriented, and impregnative iron-oxides pedofeatures. The b-fabric was defined as stipple speckled, poro- and granostriated, locally (monostriated ressembling stress coatings. There are almost no clay coatings except for very few fine internal ones that are light yellow and homogeneous; clay and iron pseudomorphs (alteromorphs occur over some skeleton grains. Many of these properties are related to the clay mineral composition. There are varying quantities of smectites and kaolinite-smectites, whereby the former increase with depth. The presence of expanding minerals is known to contribute to the disintegration of coatings. Remnants of these are observed in typic iron-manganic nodules. In terms of WRB, this horizon is an intergrade between cambic and argic, which is not accounted for in soil diagnostics. As three different Zheltozems are studied in the same area, the following genesis of this specific intergrade can be given. The saprolite in one of the profiles is composed of fragments of weathered calcareous argillites

To effectively use the very shallow seismic reflection for active fault survey, a method has been investigated by which fault structures can be appropriately reconstructed from the fault information detected in the original records. The first step of reconstructing the fault system from the travel time reflection curve was to grasp an outline of fault structure from the patterns of travel time curve observed in the original record. For the very shallow seismic reflection method, especially, the low velocity layers in a shallow part succeeding from the ground surface made the issue complicated. Then, the travel time reflection curves were calculated in the case of existing several horizontal reflection surfaces in the surface layer. The constant values, mean velocities to the depth at individual reflection surfaces were used for the approximation of velocities. The outline of fault structure was grasped from the observation of original record. Then, the structure was reconstructed from the travel time curves. When the mean velocity in the medium was known, reconstruction of the feature of reflection surfaces from the travel time curves could be determined by simple mapping. When the mean velocity was unknown, it was calculated using the reciprocal travel time from the common reflection surface for individual reflection surfaces. 7 figs.

Data processing techniques have been investigated for clarifying structures and physical properties of geothermal reservoirs in the deep underground by seismic exploration using multiple wells. They include the initial motion time-distance tomography, amplitude tomography, diffracted wave tomography, and structure imaging using reflected wave or scattered wave. When applying these data processing methods to observed records, weak and minor signals essentially required are canceled due to averaging the analytical fields. In this study, influence of inhomogeneous media on the wavefield was evaluated. Data were analyzed considering frequency by using wavelet transform by which time-frequency can be easily analyzed. From the time-frequency analysis using wavelet transform, it was illustrated that high frequency scattered waves, generated by scatterer like cracks or by irregularity on the reflection surface, arrive behind direct P-wave and direct S-wave. 5 refs., 8 figs.

A theoretical study has been made of film condensation in helically-grooved, horizontal microfin tubes. The annular flow regime and the stratified flow regime were considered. For the annular flow regime, a previously developed theoretical model was applied. For the stratified flow regime, the height of stratified condensate was estimated by a modified Taitel and Dukler model. For the upper part of the tube exposed to the vapor flow, numerical calculation of Laminar film condensation considering the combined effects of gravity and surface tension forces was conducted. The heat transfer coefficient at the lower part of the tube was estimated by an empirical equation for the internally finned tubes developed by Carnavos. The theoretical predictions of the circumferential average heat transfer coefficient by the two theoretical models were compared with available experimental data for four refrigerants and four tubes. Generally, the annular flow model gave a higher heat transfer coefficient than the stratified flow model in the high quality region, whereas the stratified flow model gave a higher heat transfer coefficient in the low quality region. For tubes with fin heights of 0.16 {approx} 0.24 mm, most of the experimental data agreed within {+-} 20% with the higher of the two theoretical predictions. (author)

Light concentration characteristics of Fresnel lenses were analyzed by using photometry. Light concentrating systems include a reflective system represented by a rotary parabolic mirror, and a refractive system represented by the Fresnel lens. The refractive system has a focused section broadened as much as the dispersion effect in association with refraction, and cannot derive a focus with high magnification as compared with the reflective system which can achieve it. The refractive system causes reduction in collected light intensity to about half on a parax, hence a large amount of loss. However, the system can be made available inexpensively due to mass production by using mold formation. Although it is difficult to utilize all of the light, 95% of the received radiation is concentrated in an opening area with a radius of about 4G (G is a radius of an image of solar light at a focus plane which passes through the center of a Fresnel lens). The average magnification of light concentration at this time in the opening area reaches 390 times. When a 3-D compound parabolic concentrator (CPC) with a radius of 4G is placed on a lens focus as a secondary light concentrator, the final magnification of light concentration shows a value of about 2700 times, whereas restoration of 39% is possible, as compared with a rotary parabolic mirror. The system has sufficient possibility to be used for high-temperature light concentration. 3 refs., 5 figs., 1 tab.

On direct injection gasoline engine, in order to achieve good stratified combustion, the extremely advanced control of air-fuel mixture is required. For this purpose, the method of diagnosing the quality of the state of mixture formation in combustion chambers becomes necessary. In this research, the state of air-fuel mixture in the combustion chamber of a TOYOTA D-4 was analyzed in space and time by visualization, A/F multi-point measurement and A/F high response measurement, thus the effects that injection timing, swirl and fuel pressure exerted to mixture formation were elucidated. 3 refs., 17 figs., 1 tab.

Intracellular signaling from receptor tyrosine kindles in mammalian cells results in activation of a signal cascade that includes the guanine nucleotide binding protein Ras and the protein kinases Raf, MEK [Mitogen activated protein kindle (MAPK) or Extracellular signal regulated kinase (ERK) kinase] and MAPK. MAPK activation that is dependent on the coupling of Ras and Raf was reconstituted in yeast. Yeast genes were isolated that, when overexpressed, enhanced the function of Raf. One of them is identical to BMH 1, which encodes a protein similar to members of the mammalian 14-3-3 family. Bacterially synthesized mammalian 14-3-3 protein stimulated the activity of Raf prepared from yeast cells expressing c-Raf-1. Thus, the 14-3-3 protein may participate in or be required for activation of Raf. 9 refs., 2 figs.

A program was developed for the inversion interpretation of the mise-a-la-masse data, and was applied to a numerical model experiment and to the study of data obtained by actual probing. For the development of this program, a program was used that calculated by finite difference approximation the potential produced by a linear current source, and studies were made through forward interpretation, inversion interpretation of the acquired apparent resistivity data, comparison with the true solution, accuracy and tendency, and the limitations. In the simulation of a horizontal 2-layer model, the parametric value after 20 repetitions converged with deviation of 1% or lower. This program was applied to the data from probing the Hatchobara district, Oita Prefecture, using a model wherein the target area was divided into 5 from east to west, and into 2 in the direction of depth. The result suggested that there was a large-scale low-resistivity body deep in the ground in the southeastern part of the investigated area. Furthermore, there was a spot detected in the direction of east-northeast that suggested an electric structure continuous in the direction of depth and a fault-like structure discontinuous in the transverse direction. 7 refs., 9 figs.

This paper introduces examples of image data analysis on fault drilling samples. The paper describes the following matters: core samples used in the analysis are those obtained from wells drilled piercing the Nojima fault which has moved in the Hygoken-Nanbu Earthquake; the CORESCAN system made by DMT Corporation, Germany, used in acquiring the image data consists of a CCD camera, a light source and core rotation mechanism, and a personal computer, its resolution being about 5 pixels/mm in both axial and circumferential directions, and 24-bit full color; with respect to the opening fractures in core samples collected by using a constant azimuth coring, it was possible to derive values of the opening width, inclination angle, and travel from the image data by using a commercially available software for the personal computer; and comparison of this core image with the BHTV record and the hydrophone VSP record (travel and inclination obtained from the BHTV record agree well with those obtained from the core image). 4 refs., 4 figs.

As observation results on the time-dependent change in the ring-opening reaction of novolac epoxy resin with acetic acid by MALDI-TOFMS, the epoxy ring was opened with reaction time, the hydroxy group formed by the ring-opening reaction was acetylated, those components were measured. In the case of the FABMS/MS observation of materials and the reaction products, the estimation structure could be confirmed from the measured results of MALDI-TOFMS. In the polymerization of bisphenol A epoxy resin with N, N`-dimethylethylenediamine, it was observed by MALDI-TOFMS that many kinds of polymers with high molecular weight were formed with an increase of reaction time. In this case, the LSIMS/MS observation of materials and the reaction products was carried out, the estimation structure could be confirmed from the measured results of MALDI-TOFMS. 19 refs., 8 figs.

An analysis method in which the technique of a vehicle obtained when a three-dimensional singular point distribution method and Kagemoto`s mutual interaction theory are combined was expanded for the fluid area was proposed as the structural analysis of very large semi-submersibles in waves. A partial structure method is used for the structure. In a fluid area, the number of unknown quantities appearing in a final expression could be largely reduced by introducing the new concept of a group body. In this process, both hydro-elasticity and hydrodynamic mutual interaction are considered. As a result, floating bodies that could not be previously calculated can be modeled as a three-dimensional frame structure and the response analysis in waves can be carried out without damaging the accuracy. The calculation result is used as the input data required for analyzing the structural fatigue locally during structural design of very large semi-submersibles in the 3,000 (m) class. This study can present a series of procedures between the response analysis of very large floating bodies in waves and the structural design. 11 refs., 14 figs., 1 tab.

Fault analysis is required in addition to the ordinary process of structural analysis (CDP stacking) for the examination of discontinuity in the reflection horizon in question. The fault shape restoration principle is that the reflection point of a reflection wave observed at a certain receiving point is on an ellipse with the shock point and receiving point at its focal points and that the sum of the distances between the reflection point and the focal points is equal to the reflection wave propagation time. The DMO velocity is worked out by calculation using the positive travel time and inverse travel time from the common reflection surface. When the reflection surface is inclined by {theta}, the average interval velocity/cos{theta} is called the DMO velocity. When the reflection surface inclination and the average interval velocities are determined separately in this way, the position of the reflection point may be worked out, and this enables the calculation of the amount of migration (lateral movement). The reflection wave lineups carried by the original record are picked up one by one, and the average interval velocities are treated very prudently. After such a basic DMO conversion treatment, the actualities of the fault are described fairly correctly. 3 figs.

This paper reports analytical examples, on an oxidized film on the surface of aluminum alloys for automobiles, using the conventional method for a surface analysis or a new method entirely different from it. For example, (1) a new method was proposed which evaluated the thickness of MgO layers on the surface of Al-Mg alloy by means of a colorimeter. In the case where the thickness of the oxidized film was several tens of nanometers or less, the chromatic value of L, b, etc., and the thickness of the films were in one-to-one correspondence to each other; therefore, the MgO film was easily estimated non-destructively by measuring the chromatic values of the surface. (2) An analysis was made on the state of adhesion of the organic matters in the oxidized film on Al-Mg-Si alloy by means of an angle-resolved XPS (X-ray photoelectron spectroscopy) depth analysis. Consequently, it was elucidated that a fatty film adhered with hydrophilic groups faced to the oxidized surface and with hydrophobic groups faced to the outside, and that this adhered fatty acid also formed a metallic soap by a heat treatment, deteriorating the fattiness. Further, the paper also reports on the analysis of crystal structures on the surface layer with the use of GIXD (grazing incidence-angle X-ray diffraction). 22 refs., 15 figs.

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.

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.

Described herein are the results of the FY1994 research program for analysis and evaluation for thin substrate polycrystalline solar cells. In order to analyze the structures of the grain boundaries in and interfaces with the cell substrate, and their effects on electrical activity, the photoluminescence (PL) measurement which enables spectroscopic analysis is applied to electromagnetically cast Si crystals. There are good correlations among PL luminous intensity, MBIC output and dislocation density for the grain boundary which contains many strains and serves as the dislocation source, because carriers in such a grain boundary easily disappear to reduce its luminous intensity at the band ends. Concrete scenarios for realizing thin-film silicon solar cells of high efficiency are presented, based on the analysis of the light-contained thin-film silicon solar cells of high output current, made in the previous year on a trial basis. An alumina substrate of high reflectivity is produced by the experiments of combining various devices. It is expected to realize high output current for the thin-film solar cells. 3 figs.

Temperature structure and its historical change around volcanos has been of interest for volcanology, geothermal development, etc. Magmatic intrusives have temperatures ranging from 700 to 850 degree C. Thus, there exists super-critical fluid around them. Numerical modeling of temperature changes around young volcanos and their heat sources thus requires treatment of the super-critical fluid. We describe one method for effective treatment of the super-critical fluid in the numerical modeling of porous media for the purpose of solving large-scale high-temperature problems of such phenomena.

Demand has been building up for an individual dry type scrubber for treating exhaust gas from the semiconductor manufacturing process. Some factors for the wide acceptance of such a scrubber would be the capability for complete treatment, easy maintenance and safety features, etc. Practical gas analysis and optimum scrubbing techniques would have to be applied, as well as effective monitoring, alarm, and fail-safe techniques. The overall exhaust gas line, i.e. the line connecting the scrubber system and the upstream process, including that extending to pump system, has to be fully considered for enabling effective scrubbing performance. Such factors, which have until now not been given any priority, would have to be fully studied for the development of a practical, individual dry type scrubber. Cooperation on this matter from the semiconductor manufacturing industry would also be essential. 6 refs., 3 figs., 5 tabs.

Objective of elevators plural control system for performing the operation control of multiple elevators is to improve the service to users. The service improvement toward a conventional plural control system is mainly to reduce waiting time on the riding floor from the calling button being pushed till elevator reaching the riding floor. Subsidiary to it, merely energy-saving is carried out. In the present study, a characterized supervisory control system was developed to make plural supervisory control receiving the requests from users to reduce not only the usual waiting time but also riding time and congestion inside. In order to meet the requests of users, a characterized support equipment was produced dialogically by combining fuzzy ratiocination, production system as well as simulation. The effects thereof were confirmed. 12 refs., ll figs., 2 tabs.

Concerning the second harmonic generation(SHG) of diode laser pumped solid state laser using a nonlinear optical material, the researches are carried out to pracitically apply to the optical pickup. Therefore, the reduction of output optical noise has become the important researching subject. The theoretical and experimental analyses of noise generating mechanism were carried out for the system in which Nd;YAG as the laser diode and KTP (KTiOPO {sub 4}) as the nonlinear optical crystal were used. The following findings for the noise generating mechanism could be obtained: The competitive interaction between the polarization modes was dominant noise mechanism in the high frequency range from 1 to 20MHz and the noise could be removed sufficiently by using the QWP(quarter wave plate). On the other hand, the noise observed in the low frequency range from 100 to 200kHz depended on the resonance length, agreed qualitatively with the theoretical analysis of the noise to the competitive longitudinal modes and agreed quantitatively with the noise generating frequency range. 10 refs., 13 figs., 1 tab.

It is considered that the reduction of oil control ring tension is a major problem in reducing the friction-loss of internal combustion engines. The authors have successfully developed a calculating method for the axial behavior prediction of a three piece type oil control ring as a method used in reduction of lube-oil consumption when lower tension ring is used. By means of the method, the authors found that the effect in reduction of lube-oil consumption was able to be expected by optimizing design parameters of the oil ring, the tension and the seating tab angle of expander-spacer, and the gas pressure on the 3rd land. 3 refs., 14 figs.

From the sonic prospecting on the ground, it was confirmed that faults distributed in the inner part of Suruga Bay extend near the Fujigawa river mouth. While, faults in the sea bottom were found by the sonic prospecting using a single air-gun. However, continuity of faults running from the land to the sea has not been reported. This paper describes the continuity of Fujigawa fault system running from the land to the sea around Fujigawa river mouth along the subduction zone of Philippine Sea Plate using single air-gun seismic reflection records. Locations of the faults can be expressed as fracture information of linearment obtained from the satellite remote sensing images, which agreed well with those found by the Active Fault Research Association. As a result of the image processing, they agreed distinctly with the topography of Fujigawa fault system. Thus, much more accurate analysis can be performed by comparing the regional information by the remote sensing with the sonic seismic reflection profiles. 3 refs., 2 figs.

Introduced herein is a reflection wave velocity analysis method using model scanning as a method for velocity estimation across a section, the estimation being useful in the construction of a velocity structure model in seismic exploration. In this method, a stripping type analysis is carried out, wherein optimum structure parameters are determined for reflection waves one after the other beginning with those from shallower parts. During this process, the velocity structures previously determined for the shallower parts are fixed and only the lowest of the layers undergoing analysis at the time is subjected to model scanning. To consider the bending of ray paths at each velocity boundaries involving shallower parts, the ray path tracing method is utilized for the calculation of the reflection travel time curve for the reflection surface being analyzed. Out of the reflection wave travel time curves calculated using various velocity structure models, one that suits best the actual reflection travel time is detected. The degree of matching between the calculated result and actual result is measured by use of data semblance in a time window provided centering about the calculated reflective wave travel time. The structure parameter is estimated on the basis of conditions for the maximum semblance. 1 ref., 4 figs.

Data, collected from an MT method-assisted survey conducted in the Kakkonda geothermal region in 1987, was re-examined, and a new structure was found. The review was carried out by use of a 2D analysis in the TM mode. According to the 1D analysis of 1987 and the geological data gathered then, it is estimated that the resistivity structure of this region runs in the northwest-southeast direction. A northeast-southwest traverse line was set for this analysis, orthogonal to the strike, and the impedance at each observation spot was caused to rotate to this direction across the whole range of frequency. Furthermore, in 1994-95, surveys were conducted using arrayed CSMT/MT methods. All these sum up to indicate that a high-resistivity region extends northwest in the southwestern part of the Kakkonda river but that there exists a low-resistivity region of several 10 Ohm m centering about the B traverse line. The high-resistivity region deep in the ground being the target of excavation in the Kakkonda region, to collect knowledge about this high-resistivity is important, and here the effectiveness of the 2d analysis has been verified. 5 refs., 11 figs.

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

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

The objective of present study is to show the aerodynamic effectivity of a horizontal axis wind turbine rotor blades with winglets by means of numerical analysis. The winglet used in this study is considered to be an inclined extension of the blade. For the numerical analysis a vortex lattice method with a free wake model was used because the model can be fitted to an arbitrary blade shape and needs no empirical parameter about wake geometry. The calculations were made on the flow field in the rotor wake and the rotor performance, and the results were compared between the rotors with and without winglets. In order to examine the structural effects, the flap bending moment was also compared. The results shows that small installation angle of winglets is found to cause a larger increase in the power coefficient and a smaller increase in the flap bending moment than radially extended rotor blades. 11 refs., 13 figs., 1 tab.

This paper summarizes the current status of water quality and pollution sources in Poyang Lake in China. The lake is located in Chianghsi Province of China, and a largest fresh water lake in China that flows out into the Yangtze river. The basin is surrounded by mountains on three sides and faces the Yangtze on one side, whereas the plains formed by the lake and the rivers flowing in extends in the center of the basin. The plains around the lake has the city of Nanchang, the capital of the province, the city of Jiujiang (both cities have a population of about 4 million, respectively), and four other cities with a size of one million people including Jingdezhen. Water supply system in the basin is used in a 37% area of the urban areas, and no sewage facilities of whatsoever are available as of 1991. The lake has COD of about 3 mg{times}1/l. No severe pollution by organic matters is seen. While the T-P concentration is at a high level, PO4-P is low. Majority of phosphorus flowing into the basin exists in the form trapped in soil particles. In order to maintain the current water quality in the future, waste water treatment is required in the basin. Construction of an oxidation pond in the vast land exposed during the drought period is a measure that can be tackled relatively easily. 1 fig., 4 tabs.

Alpha activities as a basic component of EEG (electroencephalogram) are mainly observed with eye-closed and reported state, and indicates rhythmic and diffused pattern on the scalp. Therefore analysis of the relation among many sequences of alpha activities measured at different positions on the scalp is expected to be useful not only for diagnosing psychiatric but also for investigating mechanism of brain information processing by means of causality analysis that is, macroscopic estimation of flow pattern within brain. Although coherence analysis has been proposed as a method for estimating the direction and magnitude of information flow between two sequences, superposition of results for each pair of sequences can not represent true relation among the whole sequences. In this paper, we proposed the multidimensional directed coherence analysis by modifying two-channel formula in order to apply it to the analysis of multi-channel sequence of alpha activities. Results of simulation revealed that multidimensional directed coherence can indicate more quantitatively the relation among the multi-channel sequences compared with conventional two-channel formula. Moreover, the proposed method was applied to the analysis of EEG data of normal volunteer and patient. Results show the method can provide a useful diagnostic information by assessment of the signal flow pattern within brain. 16 refs., 10 figs.

This paper describes the results from the qualitative analysis of magnetic anomalies offshore of western Kyushu and from an analysis by a three-dimensional two-layer model inversion. The analysis ranged from Kyushu on the east to Jeju Island on the west and from the southern part of the Korean Peninsula on the north to Tanegashima and Yakushima Islands on the south, namely, the area of 580km from east to west and 580km from south to north. The analytical data used was Magnetic Anomaly Map of Asia (GSJ and CCOP, 1994). In the qualitative analysis, a pseudogravity anomaly map and a pole gravity anomaly map were prepared from the total magnetic force anomaly map by means of a frequency filter operation. As a result, it was noted that two distinctive magnetic high belts existed in the margin of the Tunghai Shelf, extending from the sea area to the west of the Nansei Islands continuously to NNE, and being distributed transversely through the Goto sedimentary basin. Additionally, in the inversion analysis, it was demonstrated that the magnetic basement became shallow at the margin of the Tunghai Shelf north of latitude 31 degrees north, extending nearly in the NNE direction through west of the Goto Islands, west of Tsushima Island, and continuing to the southern coast of the Korean Peninsula. 6 refs., 4 figs.

An examination was made, in the two dimensional tectonic analysis by gravity exploration, on a method that was applicable from a deep underground part to a shallow geological structure by using logarithmic functions. In the examination, a case was considered in which an underground structure was divided into a basement and a covering formation and in which the boundary part had undulations. An equation to calculate a basement structure from a gravity anomaly was derived so that, taking into consideration the effect from the height of an observation point, it might be applicable to the shallow distribution of the basement depth. In the test calculation, a model was assumed reaching the depth near the surface with the basement being a step structure. Density difference was set as 0.4g/cm{sup 3}. An analysis using an equation two-dimensionally modified from Ogihara`s (1987) method produced a fairly reasonable result, showing, however, a deformed basement around the boundary of the step structure, with the appearance of a small pulse-shaped structure. The analysis using logarithmic functions revealed that the original basement structure was faithfully restored. 3 refs., 5 figs.

Detecting strand breakage and local wear of elevator wire rope uses currently a method using a rope tester. This method magnetizes a rope with electric magnet and detects defected part as leakage flux. Pulsed signals are issued from the defected part, variation in magnetic flux leakage due to rope swinging produces noise, and both get mixed together. Therefore, the detection is performed finally by visual check and palpation. This paper discusses a method that analyzes measurement data derived by the rope tester by using wavelet conversion, and detects the defected part automatically without being confused by noise. The pulsed signals generated from the defected part can be detected from noise by decomposing multiplex resolution using the Haar basis. As a result of the experiment, cases that may be overlooked in visual check because of S/N ratio being too small or the pulsed signals being too weak were all detected. 11 refs., 14 figs.

A CFD simulation was performed to analyze the air flow in the engine compartment of a large urban bus. The conventional simulation technique takes a long time to perform the parameter study of a complex engine compartment shape. In this study, the use of orthogonal grids made modeling the engine compartment easy, so parameter study on modification of the engine compartment structure could be conducted in a short time. Thus this simulation enables engineers to more clearly understand the air flow patterns in the engine compartment, and to get guidlines for modifying the compartment structure to improve the cooling performance. 1 ref., 12 figs.

Discussions and evaluations have been performed on the safety and durability of the device installed with inverter to protect grid connection being an important device in the photovoltaic power generation system. This paper summarizes the achievements in fiscal 1996. The current fiscal year performed data collection and long-term continuous operation according to the durability test program for the device installed with inverter to protect grid connection, as the continuation from the previous fiscal year. In the electrical characteristics, although no large changes have been found in AC overvoltage and AC undervoltage, instability was observed in the detection level. With regard to temperatures in different components, the temperature rise has become nearly the same as in the maximum output continuous operation as a result of the repetition of the operation and shutdown, whereas the influence on the electrical and thermal stresses have increased. Particularly, when temperature rise in the AC side noise filter was given observation, the measurement of conductive high-frequency terminal voltage showed a value higher by several ten dB than in the previous fiscal year. The current fiscal year has gone farther to starting the measurement of noise electric field intensity as the base of electromagnetic interference. (NEDO)

Discussions and evaluations have been performed on the safety and durability of the device installed with inverter to protect grid connection being an important device in the photovoltaic power generation system. In discussing the durability test items, electrical property changes were observed on AC overvoltage, AC undervoltage, frequency rise, and frequency fall, as the continuation from the previous fiscal year, in order to evaluate temperature rise in different parts due to lapse of operation time and the effects of thermal stress in each component on the stress of the entire product. Furthermore, verification of single operation detecting function, tests on sudden input power change, sudden grid voltage change, and measurement of conductive high frequency terminal voltage were conducted in addition to the above observations. In discussing the durability test methods, repetition of operation and shutdown during the rated operation was adopted in place of the simulated operation using variation in the insolation having been discussed in the previous year. As a result of the tests, no noticeable changes were recognized from the evaluation result after a lapse of 5,000 hours from the start of the operation, as compared to those after the aging operation.

Tests and discussions have been performed on the safety and durability of the device installed with inverter to protect grid connection, being an important device in the photovoltaic power generation system. The particularly important requirements demanded in the device were specified as maintenance of electric power quality, coordination with the protection system in the grid side, and assurance of safety of personnel and facilities. The current fiscal year has performed operation corresponding to that in the actual field for 20 years in total, and the evaluation tests on electrical characteristics and electric power quality. This paper summarizes the achievements in four years including the results available up to the previous fiscal year. Although no large change has been identified in the electrical characteristics, variance has been found in the detection time of overvoltage in the grid side. With regard to the electric power quality, the value has exceeded 89 dB as the determining condition for the certification test in the conduction interfering waves of 5 kHz to 10 kHz. In addition, it was confirmed that the conductive high-frequency noise terminal voltage in the grid side after the repetition of operations and shutdowns tends to increase according to the operation lapse time.

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.

A vortex-induced vibration of an array of elastically supported tubes is simulated in two-dimension by using a flow-induced vibration analysis program, which was developed in order to evaluate flow-induced vibration in various components such as heat exchangers. From a comparison of calculated results and experimental data, the following points are observed. (1) For the calculated results in a 5 {times} 5 square array, the flow pattern surrounding the first-row tubes is markedly different from that observed in the second-row or third-row tubes. This flow pattern is the same as that obtained from the experiment. (2) All tubes begin to oscillate due to unsteady fluid force and the oscillating mode is different for each row of tubes. These oscillation patterns show the same tendency in the experiments and it is concluded that the developed method can simulate vortex-induced vibration in an array of elastically supported tubes. 19 refs., 10 figs., 1 tab.

For the physical modeling system of Technology Research Center, Japan National Oil Corporation, data acquisition on the ocean and ground can be simulated using models. This system can provide data for verification of the data processing and elastic wave simulation algorithm. This can also provide data for decision of experiment specifications by making a model simulating the underground structure of the given test field. The model used for the physical modeling system is a gradient multilayer model with six-layer structure. Depth migration before stacking was conducted using data obtained through two acquisition methods, i.e., up-dip acquisition and down-dip acquisition. The depth migration before stacking was performed for data obtained by up-dip acquisition in addition to the records obtained by down-dip acquisition. Consequently, a definite reflection surface was observed, which has not been observed from the processing results of down-dip acquisition data. 9 figs.

The Physical Modeling System introduced into the Technology Research Center, Japan National Oil Corporation, and data collected by use of the system are presented. The Physical Modeling System is 10,000 times smaller than the real one, comprising a water tub section, measuring device section, and control section, etc. The water tub section comprises a tub for housing the model, transducers for transmitting and receiving vibration, controllers, etc. The water tub measures 1.8{times}1.2{times}0.9m. The model used in the experiment is an `inclined multilayer model` with each of its six layers pinching out toward the top, and is usable for the comparison of various migration methods. In one case in the records, reception was made at 184 reception points deployed at intervals of 3mm, when the minimum offset was 15mm and the maximum offset 564mm. Nothing very obvious was observed when the ordinary overlapping of DMO and CDP was applied to this record, which suggests that pre-overlapping migration treatment is required. 5 figs.

The photovoltaic AC fusion converter (PVAC), of which cost reduction of the total system is possible, was developed. PVAC controls the supply of commercial power by preferentially supplying photovoltaic power to loads for realization of energy conservation. Further, setting the maximum output of solar cell less than the rated load, the system was made the one with no need of storage batteries. This system was realized in a hybrid of the conventional rectification technology and the stand-alone maximum power point tracking photovoltaic system technology. The solar cell input efficiency had been measured as 84% at maximum. Main losses are consumption power of power source, switching loss of inverter, and continuity loss of diode. Ninety-seven percent of the commercial power input efficiency was obtained. Main losses are consumption power of power source, continuity loss of diode bridge, and resistance loss of smoothing reactor. The effect of energy conservation by the use of PVAC was also admitted. 6 refs., 7 figs.

A floating type wave power generator system using a ball screw is proposed. Output characteristics are simulated on the supposition of its employment aboard a navigational aid buoy. The relative linear movement produced by waves between the main body and float is transmitted via a load column to a ball nut and is converted into a rotary movement of a threaded shaft engaging the ball nut. Attached to the bottom end of the threaded shaft is a one-way clutch which connects to the generator axle when the relative velocity between the float and main body is positive. The simulation was conducted for a wave activated power generation buoy, 2.6m in outer diameter, 4.5m in length, and 6000kg in total mass. The buoy generated a mechanical output of 340kW when exposed to a sinusoidal wave 2.5 seconds in period and 40cm in wave height. A tank test was performed using a reduced scale model consisting of a ball screw, bicycle dynamo, and float, with the main body being 318mm in diameter and 833mm in length, when an average output of 4.51W was obtained at 60% efficiency. The results of the experiment agreed in some degree with the results of calculation, verifying the righteousness of the theoretical formula. 3 refs., 7 figs., 4 tabs.

The use of a commercial jet transport airplane over its life of 20 years has been increasing because of intestified competition after cancellation of the regulations. It is necessary that users of the airplane adopt such a positive way as they themselves maintain safety of their airplanes rather than they wait for feedback or technical instructions from manufacturers. This paper outlines the points at issue regarding the problem of fatigue strength which is fundamental to the safety problem, explaining by various examples that the fatigue strength problem includes phenomena of which theoretical elucidation has not been obtained. Consequently, some points to be paid attention to are cited. For instance, in the analysis of reliability in case of determining the period for initial inspection (safety life), reliability should be 95-99% which have been advised by Boeing and others, even if confidence level is 95% as usual In case of considering a fleet number in the reliability analysis, the fleet number should be reflected by grouping significant in fatigue analysis. 30 refs., 10 figs., 1 tab.

Nozzles in fuel injectors for direct injection gasoline engines are exposed to high temperature combustion gases and soot. In such a rigorous environment, it is a fear that fuel flow rate changes in injectors by deposit formation on nozzles. Fundamental factors of nozzle deposit formation were investigated through injector bench tests and engine dynamometer tests. Deposit formation processes were observed by SEM through engine dynamometer tests. The investigation results reveal nozzle deposit formation mechanism and how to suppress the deposit. 4 refs., 8 figs., 3 tabs.

Concerning the analysis of data obtained by the seismic reflection method, migration in the very shallow layer is discussed. When the dip angle of the reflection plane involved is disclosed by DMO conversion, the amount of migration (travelling sideways) can be calculated by use of simple geometrical formulas though on the presumption that the sector velocity is constant. Categorized into this technique are such methods as DMO conversion migration, direct dip migration, F-K method, and finite difference method. This means that waveforms are not damaged by migration processing although elongation occurs due to time base conversion. When it is taken into account that waveform distortion is generally grave in the migration related methods widely in use, this feature has to be said valuable in holding information on faults. This is especially advantageous in the very shallow layer because the amount of migration is proportionally larger when the level is deeper and, in addition, migration processing is useful when it is necessary to know more accurately the character of the fault plane. 8 figs.

Concerning seismic reflection survey for geometrical arrangement between pits, the scattering stacking method with stacking velocity analysis is compared with the CDP (common depth point horizontal stacking method). The advantages of the CDP supposedly include the following. Since it presumes an average velocity field, it can determine velocities having stacking effects. The method presumes stratification and, since such enables the division of huge quantities of observed data into smaller groups, more data can be calculated in a shorter time period. The method has disadvantages, attributable to its presuming an average velocity field, that accuracy in processing is lower when the velocity field contrast is higher, that accuracy in processing is low unless stratification is employed, and that velocities obtained from stacking velocity analysis are affected by dipped structures. Such shortcomings may be remedied in the scattering stacking method with stacking velocity analysis. Possibilities are that, as far as the horizontal reflection plane is concerned, it may yield stack records higher in S/N ratio than the CDP. Findings relative to dipped reflection planes will be introduced at the presentation. 6 refs., 12 figs.

The diastrophism by the earthquake-induced dislocation is investigated by interferometry (INSAR) which represents the diastrophism by the interference fringes of equiphase difference lines. A joint research group at Geographical Survey Institute and National Space Development Agency showed the diastrophism in the vicinity of the ground surfaces before and after the Hyogoken Nanbu Earthquake by the INSAR interference images in 1995. This paper discusses the effects of observation in the vision line direction from the satellite and dislocation parameters on the interference images. The dislocation model uses a slanted rectangular model in a semi-infinite medium, to calculate static displacements and strain distributions at the ground surface, when dislocation changes. It is found that the INSAR interference images, detecting displacements in the vision line direction from the satellite, significantly change as the vision line direction changes, and that the actual displacement cannot be given by the images alone. This paper also shows sensitivity of the interference images to the dislocation parameters. 3 refs., 9 figs., 1 tab.

In this study, the improved fluxoid quantum dynamics method which applied the handling of the lattice in the lattice gas automaton method into the fluxoid quantum dynamics was developed. The saving of a memory capacity and the speedup of the calculation were carried out. Using a BSCCO single crystal which introduced a pinning center by the heavy ion irradiation as an analysis object, the validity of this technique was shown by the comparison with the experimental result. By the improved fluxoid quantum dynamics method, the space was made discrete by the triangular lattice in the two-dimensional system. The fluxoid quantum exists only on the lattice point, and received the force from the fluxoid quantum, the Meissner magnetic field and the pinning center in the circumference, and then moved to the 6 neighboring lattice points. Since the pattern of the positional relation of the fluxoid quantum was limited by the use of triangular lattice, the high-speed computation became possible by storing the interaction force into a database. The dependence for the radiation value of the torque in the axial type super-conductive magnet bearings was analyzed, and the possibility of the rotational loss control by the heavy ion irradiation was shown.

With regard to the elastic wave exploration, discussions have been given on the relationship between frequency and resolution in P-wave velocity tomography using the initial travel time. The discussions were carried out by using a new analysis method which incorporates the concept of Fresnel volume into tomography analysis. The following two arrangements were used in the calculation: a cross hole arrangement, in which seismic source and vibration receiving points were arranged so as to surround the three directions of a region extending 250 m in the horizontal direction and 500 m in the vertical direction, and observation is performed between two wells, and a permeation VSP arrangement in which the seismic source is installed on the ground surface and receiving points installed in wells. Restructuring was performed on the velocity structure by using a total of 819 observation travel times. This method has derived results of the restructuring according to frequencies of the seismic source used for the exploration. The resolution shown in the result of the restructuring has become higher as elastic waves with higher frequency are used, and the size of the structure identified from the restructuring result has decreased. This fact reveals that sufficient considerations must be given on frequencies of elastic waves used according to size of objects to be explored. 4 refs., 4 figs.

Recently, span of cable-stayed bridges has been getting loner and longer, present situation is that cable-stayed bridges with span 600 to 800m class have been built inside and outside the country, and accurate determination of its ultimate strength has been an important problem statistically. However, concrete design method for evaluating load bearing stress of long-span cable-stayed bridge. Particularly of the main beam whose axial stress is dominating, has not been established so far. As for cable-stayed bridge, even for long-span, effect of plasticization of cross section on ultimate strength is severe because there is little effect of geometric nonlinearity and it is thought that accurate evaluation of ultimate strength only by elastic finite potential analysis is difficult. Accordingly, it is necessary to study the behavior by using combined nonlinear analysis considering the nonlinearity of the material in order to evaluate the safety and economy to long-span cable-stayed bridge. In this report, 3 dimensional analysis method was formularized taking into account the combine nonlinearity of multi-box girder and analysis program of ultimate strength behavior of long-span cable-stayed bridge was developed. 19 refs., 17 figs., 2 tabs.

Remaining life assessment technologies for polymeric materials for geothermal power generation and methods for improving their heat resistance are reviewed, and concepts of scale-free technologies for FRP (fiber-reinforced plastic)-sandwiched pipelines for hot water transportation are described. Materials based on PTFE (polytetrafluoroethylene) and NBR (acrylonitrile-butadiene rubber) are chosen for use as DHM (down-hole motor) sealing material and for application to the stator. With PTFE as the matrix, four candidates are prepared, which are additive-free PTFE, and GF/PTFE, GF/CF/PTFE, CF/PTFE, each containing 20w% GF (glass fiber) and/or 20w% CF (carbon fiber). With NBR serving as the matrix, two candidates are prepared, which are NBR-A containing 20w% aramid fiber and NBR-W which is a vulcanized NBR-A. External force, heat, light, and mud are named as the degradation factors, and each factor and some combinations of external force, heat, and light are repeatedly imposed on the materials. During the effort to develop an apparatus for simulating geothermal circumstances in which the factors will affect the materials in complicated ways, a life assessment technique is developed for such polymeric materials. A technology is developed for providing polymeric rubber elastomer with a heat resistant feature. A study is made to replace transportation pipelines for injection wells with FRP sandwiched pipelines. (NEDO)

To document the distribution of sociodemographic markers (race and relative access to wealth) in athletes participating at the summer and Winter Olympic Games (OGs). Cross-sectional descriptive epidemiological study. Sociodemographic data were collected from publically available resources for all athletes representing four countries (Canada, United States of America, Great Britain and Australia) at the 2014 Sochi Winter OGs and 2016 Rio Summer OGs. The prevalence of white and privately educated athletes were identified for each sport, country, and team with consideration and comparison to the general population. Access indices (i.e. the combined race socio-economic access index [CAI]) were developed to describe the relative distribution of white and privately educated athletes representing each sport, country and team compared to the respective general population. A total of 568 winter and 1643 summer athletes were included in this study. Privately educated athletes constituted 30.3% and 32.7% of winter and summer athletes, respectively; while 94.9% of winter and 81.7% of summer athletes were white. The CAIs of the Canadian, American, British and Australian winter Olympic teams were 0.52, 0.42, 0.61 and 0.45, respectively. The CAIs, for the Canadian, American, British and Australian summer Olympic teams were 0.89, 1.13, 0.82 and 0.83, respectively. Summer and winter sports with the greatest and least racial and socio-economic biases were identified. Racial and socio-economic biases were identified in both summer and winter Olympic sports; predominantly favouring white and privately educated Olympic athletes. These findings prompt further inquiry into barriers for sport-specific participation and advancement, in addition to the practice of providing substantial public resources in support for Olympic sports and athletes.

Full Text Available Russia is actively trying to raise its image and rating in the international political, sports and social spheres. This can be achieved by hosting major All-Russian and international events such as APEC 2012 summit, the 2013 Summer Universiade, the XXII Olympic Winter Games and XI Paralympic Winter Games 2014, FIFA 2018, 2019 Winter Universiade etc. We point to the absence of complex scientific approach to managing such event-strategic megaobjects, and this has negative affect on the Russian economy. The subject of the present research is represented by the role of state event-strategic megaobjects in sustainable regional development of Russia. The analysis allowed to identify a number of features of these objects, and to point out key issues and risks in their implementation. We consider the use of innovative crowdfunding technology to be the positive aspect of public megaobjects’ management. The negative aspects include the excessive scale of the financial costs and problems of cost-effective use of megaobjects after the hosting events. The territorial aspect of the analysis revealed the absence of a systemic approach to the selection of regions for hosting international events, as well as the unevenness of the territorial distribution of megaobjects. The largest event-strategic megaobjects were implemented in the Far Eastern Federal district (APEC summit in Vladivostok in 2012, the Southern Federal district (Krasnodar region, Sochi – The winter Olympic and Paralympic games in February 2014, Volga Federal district (the Universiade in Kazan in 2013. These districts did not become the leading regions in socio-economic development of Russia neither before nor after these events. The studies of such socio-economic and political phenomena will help to present theoretical and practical aspects of their application algorithm in the future for the purpose of balanced regional development of Russia.

Within several investigated endurance sport disciplines the distribution of load of the best competitors has a manner of evenly or slightly rising velocity values. Unfortunately many other competitors have usually diminishing values or when they are very poor they have evenly values. The aim of this study was to investigate distribution of velocity within 30-km cross-country female skiers. Cross-country skiing runs were investigated of Olympic Games 2002-2014 (Salt Lake City, Turin, Vancouver, Sochi). At every race two 15 km or three 10 km loops of the same vertical profile were taken into account. The competitors were divided onto: A - winners, B - medallists, C - competitors who obtained places 4 to 10 at the finish line (medium runners), D - competitors who obtained places 11 to 30 at the finish line (poor runners). Velocity data presented on the web pages of several institutions were utilized. The competitors had their velocity distributed in a manner with usually diminishing values. While comparing velocity of sequential loops with the mean velocity the difference for the poor runners reached the value of almost 6 %, which was too high. There was significant (usually negative) correlation coefficient between values of velocity deviation for the first and second loops and the mean value of velocity for the entire distance for the better runners and mixed, i.e. positive and negative values for the poorer runners. It was postulated investigations of velocity distribution should be introduced in coaching in order to inform competitors about their running. This advise is especially important for the poorer runners. Up to now cross country skiers run for themselves. It should be discussed whether the tactics used by road and track runners, i.e. running with pace makers, can be introduced in cross country skiing. Also the use of a drone during training can be used in order to maintain proper pace.

HFCSMT system has been developed to enhance resolution in CSMT technology. The system covers a frequency band of 1.4kHz-106kHz for transmission, and measurement is performed using 16 frequencies. The transmitter power amplifier operating on a 12V cell is capable of a maximum output of approximately 3A, and the signals can be received at points several 100s of meters away. As for the selection of frequencies, synchronization is ensured for the receiver set no matter what instant the measuring process is commenced, the process being fully automated including the gain control. Phase and amplification values obtained for the electric and magnetic fields are subjected to A/D conversion. The data are stored in the microcomputer memory as apparent resistivity and phase data, and are forwarded to the host computer upon termination of the measuring process. Since both analog processing and digital processing are used, the measurement process is over in approximately 96 seconds. This system is being tested in various fields of technology. 1 fig.

Full waveform digital sonic tool (OYO) has been developed for the purpose of accurately measuring geophysical anomalies in the rockbed containing cracks, and its performance is evaluated by comparing its measurements with those obtained by the conventional sonic logging device (DBM). Modification involves the following. While gain is fixed in the DBM, it is variable in a times10-times200 range in the OYO. Analog transfer:ground surface A/D in the DBM is replaced by digital transfer:intra-probe A/D in the OYO. In the DBM, only a special program running on the MS-DOS can analyze waveform data but, in the OYO, waveforms are recorded in the SEG-Y format enabling the import of the data into generally available waveform processing software. In the OYO, a high-speed communication board is incorporated into the probe, which realizes high-speed communication. There is a very excellent agreement between the two in P-wave velocity distribution as reckoned from the initial run. Regarding the OYO, however, it is pointed out that gain control be performed with the greatest care to prevent waveforms from distortion. 5 figs.

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.

An analysis was made on turbulent heat diffusion in a multi-compartment structure necessary for designing calorific power and environment for functional systems used in marine vessels and off-shore structures. In a multi-compartment structure, the diffusion phenomenon is complex because of movement of air flow in turbulence and buoyancy resulted from non-isothermal condition. The phenomenon is largely affected by space shapes and walls, and the conditions in heat diffusion field is governed also by shapes of opening connecting the compartments. An analysis was made by using the SIMPLE method on turbulent heat diffusion in a multi-compartment space with high Raleigh number in which natural convection is dominant. If the opening is small, the Coanda effect appears, in which air flow passing through the opening rises along the wall, wherein a high-temperature layer is formed near the ceiling, making the heat diffusion inactive. If the opening is large, a jetting flow from the opening and a large circulating flow are created, which cause active advection mixture, making temperature gradient smaller in the upper layer. Heat transfer intensity in an opening on a partition wall decays in proportion with 1/4th power of the opening ratio. 7 refs., 11 figs.

The paper measured current/voltage characteristics of various PV modules under natural light and analyzed various characteristics such as generated output and module power generation efficiency. In the experiment, installing various PV modules at the solar techno center located at north latitude 34.7deg and east longitude 137.6deg, measurement was made by I-V curve tracer, pyranometer, and thermocouple buried on the module back. As a result, the following were confirmed: As to the monthly mean power generation efficiency, the crystalline system is lowest in summer and highest in winter, and the amorphous system highest in summer and lowest in winter. Concerning the power generation efficiency and illuminance, the gap of power generation efficiency between at high illuminance and at low illuminance is large in the crystalline system and small in amorphous system. Relating to the azimuth angle of module installation and the generated output, the installation inclined 15deg angle west in summer and 15deg angle east in fall/winter generates more power in the crystalline system. On the contrary, the installation on the south face generates more power in the amorphous system. 4 refs., 8 figs., 3 tabs.

The theory and formulation for the numerical response analysis of a large floating structure in regular waves were given. This paper also reports the comparison between the experiment in the Shipping Research Institute in the Minitry of Transport and the result calculated using numerical analytic codes in this study. The effect of the bending rigidity of a floating structure and the wave direction on the dynamic response of a structure was examined by numerical calculation. When the ratio of structure length and incident wavelength (L/{lambda}) is lower, the response amplitude on the transmission side becomes higher in a wave-based response. The hydrodynamic elasticity exerts a dominant influence when L/{lambda} becomes higher. For incident oblique waves, the maximum response does not necessarily appear on the incidence side. Moreover, the response distribution is also complicated. For example, the portion where any flexible amplitude hardly appears exists. A long structure response can be predicted from a short structure response to some degree. They differ in response properties when the ridigity based on the similarity rule largely differs, irrespective of the same L/{lambda}. For higher L/{lambda}, the wave response can be easily predicted when the diffrection force is replaced by the concentrated exciting force on the incidence side. 13 refs., 14 figs., 3 tabs.

The MAGLEV (magnetically levitated train) is now well along in development testing in Japan. MAGLEV is unlike conventional railways, so various problems lie in the technology of MAGLEV. One of them is surge analysis of the MAGLEV coil for propulsion and guidance (`coil for propulsion` for short). The coil for propulsion is installed on each side of the outdoor guideway. Thus, the power system of MAGLEV is always exposed to lightning and circuit switching. Accordingly, it is very important to do a rational insulation plan to prevent damage when surges enter the coils. In view of this situation I performed experiments using the mini model coils and clarified impulse voltage distribution at the end of each coil and simulated the surge characteristics by giving the inverted L equivalent circuit to the coil for propulsion. As a result, the measured values and calculated values were almost equal in the surge characteristics. Further, the surge characteristics of the Miyazaki test track and the future MAGLEV were examined. 10 refs., 17 figs., 1 tab.

For NOx reduction of a DI diesel engine, the retard of fuel injection timing is effective. However, it causes the white smoke at low temperature and low load. To analyze the mechanism of white smoke generation, a new visualizing system of fuel spray and flame behavior has been developed. This system can be also applied to a 4-valves per cylinder production engine by integrating two optical systems for image and lighting. From the visualization of the fuel spray and the flame behavior in the combustion chamber at low temperature, it has been proved that prompt fuel evaporation before reaching the wall surface of combustion chamber is required to reduce the white smoke. 6 refs., 10 figs., 3 tabs.

This paper will explain method of fractal analysis for heart rate variability, as measuring method of mental stress in vehicle driving. In the previous, although there was a measuring method of mental stress by RSA, a issue arise such as reliability of analysis, because driver`s heart rate affect by respiration and muscle motion as well. We have established a method to measure mental stress by fractal dimension. And tried it is the proving ground and public road driving. We have confident that it is more reliable than RSA to quantify driver`s mental stress and fatigue. 9 refs., 9 figs., 1 tab.

Described herein are the results of the FY1994 research program for analysis and evaluation of new storage batteries for photovoltaic power systems. Quantitative analysis and evaluation are made for introduction of intermittent operational mode in the conventional power supply system in which electrolyte units are connected in parallel and for improved performance by bubbles flowing into the line that supplies the electrolyte to the stack, in order to establish the configurations of and operational procedures for the redox flow batteries. The study on development of redox battery compares the Pb-Sn alloy felt collector with carbon fiber, Pb-Sb alloy felt and the lattice for the conventional lead acid battery, in order to optimize the new lead felt battery. As a result, it is found that the Pb-Sn alloy felt collector is better than any other device tested, because of its higher freedom with respect to electrode shape and battery size. The study on reliability evaluation of amorphous solar cells tests photoelectric conversion efficiency of a-Si solar cells, in order to elucidate the phenomena where degradation and rejuvenation compete with each other under weak light irradiation conditions. 8 figs., 1 tab.

Described herein are the results of the FY1994 research program for analysis and evaluation of concentrator modules for extra-high efficiency solar cells. The outdoor exposure tests have been under way for 3 years for fluorescent plates, as part of the research program for development of materials and elementary techniques, and essentially no degradation has been observed by the perylene pigment test. Coupling of the fluorescent concentrator and solar cell units is investigated for the coupling position and method, to theoretically analyze geometrical coupling efficiency, where they are coupled at the bottom faces in consideration of easiness of module fabrication. It is demonstrated that a high coupling efficiency can be realized when the cell is sufficiently wide relative to thickness of the fluorescent plate. The coupling method is experimentally examined using transparent silicon gel. A prototype module having the same size as the commercial module (420mm by 960mm) is made on a trial basis, where a total of nine 20mm-thick cells are cut out of a single-crystalline silicon solar cell, 100mm by 100mm in size, and are connected to concentrators at the bottom faces. It shows 2.3 times increased output by the test using a large-area solar simulator. 2 figs.

For the purpose of measuring in-situ resistivity without contact with the rock, a study was made about a measuring device using electromagnetic induction. This measuring device has two concentric transmission loops and a receiving point at the center of the loops, and performs focusing by canceling the primary magnetic field at the receiving point. Using this device, a trial was made to eliminate the influence of surface undulation. In the model calculation, response was calculated after the structure with a heavily undulated ground surface was replaced by a two-layer structure with the first layer provided with a higher resistivity. In the model, the first layer had a resistivity of 10000 Ohm m, and the second layer 1000 Ohm m. Using the ratio between the transmission loop radii as a parameter, relationship with the thickness of the first layer was studied, and it was found that the sensitivity to the second layer resistivity increases when the inner and outer loops are nearer to each other in terms of radius and that this eliminates the influence near the surface layer. A decision needs to fall within a scope assuring good reception because response intensity decreases as the ratio between the transmission loop radii approaches 1. 3 refs., 11 figs.

Study was made on a thermally regenerative fuel cell using solar heat. The thermally regenerative fuel cell was devised which is composed of 2-propanol liquid-phase endothermic dehydrogenation at nearly 100degC, and acetone liquid- phase exothermic hydrogenation at nearly 30degC as reverse reaction. This low-temperature dehydrogenation can relatively easily utilize a flat solar heat concentrator. 2-propanol dehydrogenation generates acetone and hydrogen. Generated acetone generates electric power in hydrogenation, generating propanol. This propanol regenerates acetone and hydrogen in dehydrogenation. The activity of Ru and Pt composite catalyst was considerably higher than that of Ru or Pt single catalyst. The activity was also higher in carbon felt or carbon cloth carrier than carbon plate carrier. The open circuit voltage of the fuel cell was estimated to be 110-120mV, nearly consisting with theoretical values. Short circuit current was also estimated to be 9-11mA, suggesting reduction of its internal resistance as an important subject. 4 refs., 5 figs., 2 tabs.

For the purpose of enhancing the efficiency of analytical processes so that those not equipped with high skill may perform a certain level of analysis and that analysis precision may be improved, some analytical techniques based on path calculation were examined. As the result, a flow of work has become feasible, wherein an early model is constructed by use of a tomography-assisted analysis to be accomplished automatedly and the result is then converted into a layer system with the velocity and thickness to be automatically corrected for the determination of the ultimate velocity layer section. Following this flow of work, almost all the parts of the work may be accomplished automatically once the travel time curve is completed. Furthermore, the calculated travel time obtained by this method can be easily compared with the observed travel time creating an opportunity to show the high reliability of this method, for this to be accepted as a standard for evaluating the accuracy of exploration. It has also been found that this method may be applied to more complicated structures which fail to satisfy the conditions for a structure to be treated by other methods such as `Hagiwara`s method.` 3 refs., 5 figs.

The transient in-cylinder air motion have been investigated for reducing exhaust emissions and improving engine performance. A commercial CFD code was used for this purpose. For analyzing under engine motoring condition, the numerical model has a moving piston, intake and exhaust ports with moving valves. As result, exhaust port performance may be analyzed under steady condition, but intake port performance have to be analyzed under unsteady condition. Because transient in-cylinder air motion during intake process is different from steady in-cylinder air motion under influence of piston surface and air viscosity. 4 refs., 11 figs.

In order to predict the three-dimensional response to vortex-induced oscillation of bridges, a model was investigated using the aerodynamic force coefficient including vortex-induced and self-excited forces, and the nonlinear response coefficient expressing constancy of response to vortex-induced oscillation. In the analysis, change of frequency in wind by the self-excited force, aerodynamic damping term, effect of the mode, and correlation of the vortex-induced force along member axis were taken into account. The aerodynamic force and nonlinear response coefficients were identified from the homogeneous and turbulent flow results of wind tunnel tests using a two-dimensional spring support rigid body model with varied damping factor. The aerodynamic damping term can be estimated from the nonlinear aerodynamic force coefficient, but it was enough to calculate it from the quasi-stationary coefficient in general bridge profiles. The correlation of the vortex-induced force was obtained from measurements of the vertical variation components of trailing flow under the resonance state, or the pressure distribution of the member surface. When comparing to the wind tunnel test of three-dimensional model of cable-stayed bridge, the response amplitude by the present analysis method was consistent well with the test results rather than by the method in which the amplitude of two-dimensional model was corrected. 10 refs., 4 figs., 3 tabs.

Full Text Available Chronic vulvovaginitis is the most wide-spread gynecological pathology among women of childbearing age. The chief causations of nonspecific vulvovaginitis are reduction in oestrogen, disturbances in vaginal acidity, intestine dysbacteriosis, local and general immune disturbances. The growth of vagina opportunistic pathogenic flora is closely connected with the increase of bacterial slimes on vagina mucus. Sulphur balneotherapy in the form of general baths and vaginal irrigations, mechanical physiotherapy promotes disruption of bacterial slimes, oestrogen elevation, immune reconstruction and vaginal biocenosis, which has positive effect on patients’ fertility level, frequency of obstetrical and perinatal pathologies.

With the purpose of developing an electromagnetic tomography system, an observation was carried out with existing equipment combined, and the data was analyzed. The measuring equipment consisted of existing borehole vertical magnetic field sensors as the sensor part, MT method receivers as the receiving device, and existing CSMT method transmitters as the transmitting device. The measuring was performed at the Richmond Field Station which was abundant in existing data and which had a comparatively simple resistivity structure. The borehole vertical magnetic field sensors were lowered inside the borehole, and signal sources were arranged at 10m apart on the traverse line in the direction from northeast to southwest with the borehole as the center. The analysis of the data was made with the use of EM1D by three models, namely, 10 ohm{center_dot}m homogeneous earth model, 100 ohm{center_dot}m homogeneous earth model, and horizontal 7 layer model prepared on the basis of electric logging results; and a comparative examination was made against the measured data. As a result, it was demonstrated that the test measurement agreed very well with the model from the electric logging results and that it was the data reflecting a resistivity structure. 8 refs., 6 figs.

On the Problems of Strategic Development of Tourism in the Regions of Russia (Case of the Krasnodar Region and the Resort City of Sochi

Full Text Available The article deals with the problems of strategic development of tourism in the economy of the Russian regions. These problems arise in the period of transition from regulatory functions of the market to the management of long-term development based on the strategic objectives and flagship projects that can achieve these goals in practice. In such a case, the tourism sector of the regional economy is suggested to be considered not within the narrow framework of the tour operator and hotel business activity as it takes place in Russia, but on the much broader scale involving 50 branches of the modern economy as it is increasingly used worldwide. The authors’ hypothesis comes from the fact that in modern conditions, the development and implementation of the strategies of the recreation and tourism industries in the Russian regions can only be effective through the creation and promotion of large diversified knowledge-based competitive regional tourism products at new technological level. The paper clearly demonstrates the group methods of regional strategic planning such as brainstorming and foresight (forecasting and future shaping. The results of the research substantiate not only the need to amend the legislative framework and the current management system of the Russian tourism, to actively elaborate and implement the regional development strategies, to carry out tourism development studies aimed at its commercial success but also the importance of convincing representation of the civilizational advantages of the Russian world and Russian civilization through the tourism.

In order to investigate characteristics of photovoltaic (PV)/thermal hybrid collectors (PV/T{sub s}) operating under varying conditions, energy equilibrium equations have been developed for numerical calculation, and the calculated results were compared with the observed ones. The calculated characteristics are close to the observed ones, both for photoelectric conversion and heat collecting characteristics, demonstrating validity of these energy equations. It is found, by comparing characteristics of PV/T{sub A} (covered with glass) with those of PV/T{sub B} (not covered with glass), that these characteristics are greatly affected by glass cover. Maximum overall excergy levels attained are 13.29% with PV/T{sub A} and 11.48% with PV/T{sub B} under the conditions of solar radiation intensity H: 800W/m{sup 2}, ambient temperature: 20degC and wind velocity: 0.5m/s, where flow rates of heat medium are 2.0times10{sup -3} and 4.0times10{sup -3}kg/s, respectively. Thus, the PV/T{sub A} system has a higher maximum excergy efficiency than the PV/T{sub B} system. The PV/T{sub A} gives water of higher temperature, demonstrating that covering the system with glass increases maximum excergy efficiency and optimum temperature. 6 refs., 5 figs., 2 tabs.

In the image velocimetry, it is generally required to detect the various velocity in each position of the flow field. But the maximum velocity which the usual velocimetry can detect has been limited in about 1 pixel per frame. Then, in order to measure the wide range of velocity vectors from the dynamic image, the improvement of performance in the image velocimetry based on a spatio-temporal correlation method would be attempted by enlarging the analytical region and by interpolating the new frame. The analytical performance of velocimetry was estimated by measuring the velocity from the flow dynamic image made artificially on the personal computer so as to simulate the flow of fluid containing a lot of small particles. As the results, the velocity range of the improved velocimetry became larger than that of the usual velocimetry. 21 refs., 13 figs., 1 tab.

This paper explains the results of research on full-length cDNA structure analysis for the period from April, 2000 to March, 2001. The outline of human genome sequence was published in June, 2000. In Japan, human gene analysis was such that, as the basic technology of the bio industry, a millennium project was decided in the budget of fiscal 2000. The full-length cDNA structure analysis is the core of the project. The libraries of cDNA were prepared using full-length and more than 4-5kbp-long cDNAs by oligo-capping method. It began from determining partial sequence data at end cDNA, and then, with new clones selected therefrom, full-length human cDNA sequence data were determined. The partial sequence data determined by fiscal 2000 were 1,035,000 clones while the full-length sequence data were 12,144 clones. The sequence data obtained were analyzed by homology search and translated into amino acid coding sequences, with predictions conducted on protein functions. A clustering method was examined that selects new clones from partial sequences. Database was constructed on gene expression profiles and disease-related gene sequence data. (NEDO)

Risk assessed structural positions in a pressurized fuselage of a transport-type aircraft applied with damage tolerance design are taken up as the subject of discussion. A small number of data obtained from inspections on the positions was used to discuss the Bayesian reliability analysis that can estimate also a proper non-periodic inspection schedule, while estimating proper values for uncertain factors. As a result, time period of generating fatigue cracks was determined according to procedure of detailed visual inspections. The analysis method was found capable of estimating values that are thought reasonable and the proper inspection schedule using these values, in spite of placing the fatigue crack progress expression in a very simple form and estimating both factors as the uncertain factors. Thus, the present analysis method was verified of its effectiveness. This study has discussed at the same time the structural positions, modeling of fatigue cracks generated and develop in the positions, conditions for destruction, damage factors, and capability of the inspection from different viewpoints. This reliability analysis method is thought effective also on such other structures as offshore structures. 18 refs., 8 figs., 1 tab.

The X-ray diffraction analysis and the MO calculations of 1H-tetrazole were carried out, in order to explain its high stability. From the X-ray diffraction analysis, five bonds in the ring have intermediate lengths between single and double bond lengths. Therefore, 1H-tetrazole is quite stable because of its aromaticity. The N1-C5 distance of 1.315A is significantly short. The molecular structure which was calculated by the ab initio MO calculation of one 1H-tetrazole molecule at MP2/6-31G* level, showed a good agreement with our experimental one, except for the abnormal short N1-C5 distance. From the calculations of dimers and trimers, 1H-tetrazole is shown to be stabilized by a strong intermolecular electrostatic interaction between the protons and the delocalized electrons over the ring.

In this report, the method of analyzing mine ventilation networks is explained in which the direct matric operation method is applied to the solution of the linear equation system introduced from the fundamental equation of the nodal head method. In other words, the fundamental equation was expressed by genelarized equation composition by using connecting functions between nodes and the algorism of a computer program was clarified. And the calculation method necessary for other ventilation netwrks analysis was shown in a concrete form. For solving the linear equation system, the matric operation method based on the modified Choleski's method was used in order to speed up the calculation and stabilize the convergence process of the solution. As examples, calculation was made on the ventilation networks of total numbers of the nodes of 8, 14, 51 and 141. From these ventilation network analyses, using a linear equation system concerning the nodal pressure correction, it was found that in the system with convergence acceleration coefficient of 1.4, the number of sequential repeating frequency of approximation Mc which was required for convergence was in the order of Mc {approx equal} 13 (cycle) for the condition that the fan pressure was constant and the convergence condition was {vert bar} AQi {vert bar}{sub max} {lt} 0.1m {sup 3}/min. 14 refs., 12 figs., 3 tabs.

In-situ resistivity measuring devices are tested for performance in relation to the principle of focusing. After numerical calculation, it is shown that in the absence of focusing the primary magnetic field will prevail and that changes in the separate-mode component will be difficult to detect in actual measurement because the in-phase component assumes a value far larger than the out-of-phase component. Concerning the transmission loop radius, the study reveals that a larger radius will yield a stronger response and that such will remove the influence of near-surface layers. Two types of devices are constructed, one applying the principle of focusing and the other not, and both are activated to measure the response from a saline solution medium. The results are compared and it is found that focusing eliminates the influence of the primary magnetic field and that it enables the measurement of changes in resistivity of the medium which cannot be detected in the absence of focusing. 3 refs., 9 figs.

Elevation of a transmission line steel tower is performed by an operator`s own force upon fixing a safety device to prevent a fall on a safety wire (SW) previously installed on a specified tower leg. It is a considerable burden for the operator to move the tower having a height of 80 to 100 m up and down several times a day. In order to reduce the fatigue, a portable, small and light-weight steel tower elevation aiding device was developed. The existing SW is used to fix the device, requiring no additional facility to be fixed on the tower. Safety assurance depends on the safety device on the SW as currently used. The device has pulling force of 50 kgf (the device operates in a range of 4 to 50 kgf to assure workability in elevation and stopping), and elevation speed of 15 to 20 m/minute (equivalent to the present work. The braking force can be adjusted in three steps at descent according to the ability of the operator). An Ni-hydrogen battery is used, capable of two returns on a tower per charge. Considering the device to be transported in mountainous area, the shape is such that a single unit can be put into a backpack. The device can also be used in general construction sites. (NEDO)

The gas turbine generator is installed to supply power to the electric equipment on the carriage, and the power generating conditions are transmitted to the ground commanding room via on-board central control system for centralized controlling. An aircraft diversion type ST6 gas turbine and a high frequency light weight generator are combined for the gas turbine generator developed this time. Single reduction planetary gear is employed for the reduction gear which connects the two units directly, the gas turbine being connected to one side and the generator to the other side with no coupling. The output of the generator is 350kW, AC 455V, and 400Hz, and power is supplied to the electric devices on the carriage after having been converted to DC 600V. Aluminium is used to reduce the weights of the soundproof enclosure and exhaust dust shell plate. 1 fig., 1 tab.

A PC cable-stayed bridge under extension construction having long span length may have long-cycle vibration generated because of wind. The vibration puts workers working on main girders into a state of seasick causing the workability to drop. Therefore, with an objective to reduce vibration occurring on the main girders during construction, discussions were given on application of an active type vertical vibration absorbing device. The vibration absorbing device is an active system that a weight is driven vertically by a hydraulic actuator. The device was developed with a target that damping ratio when a maximum extension is 120 m becomes three times that when no vibration is absorbed for a 5-span continuous PC cable-stayed bridge with a length of 675 m, a central span of 260 m, and a width of 11 m. A cage housing the weight is connected with the actuator at its top by using pins, and the weight is supported being suspended from the top of the actuator. Vibration is absorbed by utilizing reactive force generated when the weight is driven vertically by the hydraulic actuator. The hydraulic actuator contains a gas spring that supports the dead weight of the weight. Experiments have verified the effectiveness of the vertical vibration absorbing device. 4 refs., 12 figs., 3 tabs.

Although since the 1980's Japanese soy sauce manufactures have developed cross-flow membrane filtration systems to recover soy sauce from its lees, the mechanisms by which the membrane fouls during filtration have not been theoretically discussed. Calculated flux declines using a theoretical equation developed for cross-flow cake filtration were compared against experimental results involving the filtration of soy sauce lees using polysulfone ultrafiltration and micro filtration membranes. Membrane fouling due to the deposition and intrusion of soy sauce lees was evaluated from the hydraulic resistances of the membrane and the cake layer. Calculated flux declines with time agree with the experimental results. Specific resistance of the cake layer which is an adjustable parameter of the equation, decreases with increasing cross-flow velocity. Hydraulic resistance exhibited by the membranes is independent of feed flow velocity. However, the resistance of the cake layers decreases with increasing cross-flow velocity. This corresponds to the steady-state flux increase. In conclusion, the main cause of fouling in the filtration of soy sauce lees is cake layer formation. By using the cake filtration model for cross-flow, the flux decline with time during the filtration is capable of being predicted. (author)

This paper describes the following matters on application of an adaptively shifted integration technique to a buckling collapse analysis of framed structures: This method is a method in a finite element analysis using three-dimensional girder elements to arrange value integration points at optimal locations in a linear analysis if the elements are in an elastic transform condition on the whole. The method then moves the value integration points so that plastic hinge will occur in these locations immediately after part of the elements has yielded. The method was applied to analyzing an elastic buckling problem in several loading patterns for either a both-end supported or a one-end fixed beam member. A result was obtained that a number of elements required for one member is four at minimum. In a buckling analysis of framed structures, a satisfactory result was obtained by using an automatic element segmenting algorithm, which begins the analysis with one element one member, and immediately after a member is determined with a possibility of generation of buckling, splits that member only into four elements. 6 refs., 5 figs.

The levitation of bulk Y-Ba-Cu-O superconductors can be controlled using a Bi-Sr-Ca-Cu-O (Bi2223) superconducting electromagnet. It was found that stable levitation without tilting could be obtained only when the sample trapped a certain amount of fields, the minimum of which depended on the external field and sample dimensions. We employed a novel analysis method for levitation based on the total energy balance, which is much simpler than the force method and could be applied to understanding general levitation behavior. Numerical analyses thus developed showed that stable levitation of superconductors with large dimensions cen only be achieved when the induced currents can flow with three-dimensional freedom.

Model simulation technology is important for automobiles development. Especially, for the investigations concerning to ABS, TRC, VDC, and so on, the model should be the one which can simulates not only whole behaviors of the automobile, but also such internal information as torque, acceleration, and, velocity of each drive shafts, etc.. From this point of view, 4-wheels simulation model which can simulates almost over 50 items, was made. On the other hand, technique of 3-D image processing using 2 video cameras was adopted to identify the model. Considerably good coincidences were recognized between the simulated values and measured ones. 3 refs., 7 figs., 2 tabs.

This paper reports on a numerical analysis of transient response of an orthogonal-core type dc-ac converter that takes place when the external ac system connected is cut off from it. A model of magnetic circuit of the orthogonal core is presented, which has magnetic inductances to represent effects produced by hysteresis that are connected in series with magnetic reluctances, thereby making it possible to divide each of primary and secondary winding current into magnetization current associated with magnetic reluctances and iron-loss current due to hysteresis. Moreover, a numerical model of the orthogonal core is derived from expressions for non-linear characteristics of these reluctances and inductances to make use of it for analyses employing the circuit simulator SPICE. Transient response of the present converter, namely time variation of both voltage and current in its every part, to the sudden change in condition that is caused by switching off the ac system connected to its secondary side is calculated, while applying square-wave voltage to its primary side. It is noted that calculated wave forms of both secondary winding current and open-circuit voltage are fairly in good agreement with those obtained by an experiment performed on the same condition. 4 refs., 9 figs., 1 tab.

This paper reports application of a geothermal database system (GEOBASE) to analyzing subsurface structure in the Kakkonda geothermal area. Registered into the GEOBASE to analyze specific resistance structure in this area were depth information (well track and electric logging of existing wells), three-dimensional discretization data (two-dimensional analysis cross section using the MT method and distribution of micro-earthquake epicenters), and two-dimensional discretization data (altitude, and depth to top of the Kakkonda granite). The GEOBASE is capable of three-dimensional interpolation and three-dimensional indication respectively on the three-dimensional discretization data and the depth information table. The paper presents a depth compiling plan drawing for 2000 m below sea level and an SE-NE cross section compiling cross sectional drawing. The paper also indicates that the three-dimensional interpolation function of the GEOBASE renders comparison of spatial data capable of being done freely and quickly, thereby exhibiting power in the comprehensive analysis of this kind. 3 refs., 8 figs., 2 tabs.

It is well known that the landslides in Tertiary systems abundantly found in Niigata Prefecture, etc., frequently occur especially in the snow melting season or the heavy rain season. For studying the occurrence of such landslides, exploration of the actual condition of groundwater and evaluation of the strength of earth are very important even when the landslide occurring mechanism can be presumed in a relatively simple way about the soil mechanics. Therefore, great importance is attached to the observation and investigation on the groundwater level and pressure at landslide sites and stability analyses have been actively performed. However, it is considered that several fundamental problems still exist in the method for estimating the groundwater level and pressure in landslide slopes from the observation method and data on groundwater levels and pressure (pore pressure). In this paper, these fundamental problems are examined on the basis of concrete observations made by the writers on landslide slopes at Matunoyamagoe and Higashimusikame landslide sites in Niigata Prefecture for the past several years. 6 ref., 6 figs., 2 tabs.

A simulation method was developed to estimate exhaust gas flow during the gas exchange process. In this simulation, one dimensional in-cylinder gas flow calculation and three dimensional exhaust gas flow calculation were combined. Gas flow inside the exhaust manifold catalyst during gas exchange was agreed in experiments. A simulation method was applied to select oxygen sensor location. A prediction of the oxygen sensor sensitivity of each cylinder gas was presented. The possibility of selecting oxygen sensor location in the exhaust manifold using calculation was proved. 5 refs., 10 figs., 1 tab.

Discussions were given on effectiveness of the TEM-FAST ProSystem which is a portable TEM system developed recently for use in exploration of shallow subsurface resistivity. The system consists of a loop type antenna, the TEM-FAST as the main equipment, and a host computer, the host computer controlling the entire system. The system acquires transient response data in secondary induced magnetic fields lasting 4 {mu} sec to 1 m sec. The number of data is 5490 stacks in one measurement, and the data acquisition time is about three minutes. Measurements were carried out by using the TEM-FAST in the vicinity of a well, whose results were compared with those of electric logging, and discussions were given on them. Although the electric logging results had no data available for depths shallower than 35 m, the measurement results from the TEM-FAST were found highly harmonious with those of the electric logging. In addition, there were transmission and telephone lines in locations about 10 m away from the well during the measurement, but extremely high data quality was discovered. 6 refs., 7 figs., 1 tab.

Described herein are the results of the FY1994 research program for analysis and evaluation for development of extra-high efficiency silicon solar cells. It is necessary for development of extra-high efficiency Si solar cells to extend as far as possible service life of minority carriers and to develop the evaluation techniques. Noting photoluminescence (PL) observable even with Si, the method of evaluating characteristics of minority carriers, which are not limited in samples, is developed to experimentally determine their service life from transitional response of the PL characteristics. Si has an extremely low quantum effect, because it is an indirect transitional semiconductor, and needs measurement of very high sensitivity. A rapid heat annealing apparatus and others to generate carriers in the infrared and ultraviolet regions are provided in consideration that these are possible means to increase efficiency. These possibilities will be pursued by developing the annealing techniques. 1 fig.

In relation to considerations on composition of gas produced by coal gasification, the HYCOL hydrogen generation process data were analyzed. From the fact that CO concentration (Y) decreases linearly with CO2 concentration (X), element balance of gasification of reacted coal was used to introduce a reaction analysis equation. The equation includes a term of oxygen excess {Delta}(amount of oxygen consumed for combustion of CO and H2 in excess of the theoretical amount), derived by subtracting the stoichiometric oxygen amount used to gasify coal into CO and H2 from the consumed oxygen amount. The {Delta} can be used as a reference to oxygen utilization efficiency. An equation for the {Delta} was introduced. Also introduced was a term for steam decomposition amount derived by subtracting the generated steam from the supplied steam. These terms may be used as a clue to permeate into the gasifying reaction process. This suggestion was discussed by applying the terms to gas composition value during operation. According to the HYCOL analysis, when a gasification furnace is operated at higher than the reference oxygen amount, coal supply variation is directly reflected to the combustion reaction, making the {Delta} distribution larger. In an inverse case, unreacted carbon remains in the furnace due to oxygen shortage, and shift reaction may occur more easily even if oxygen/coal supply ratio varies. 6 figs., 1 ref.

Remote sensing images include information of coastal land division, sea level change such as sedimentary environment and vegetation, and distribution of artificial structures. Past sea level changes and their causes can be regionally obtained by analyzing these data and by integrating them with information obtained from geological survey. In this study, causes and history of past sea level changes, formation mechanism of coastal topography, and past sea level change survey in Thailand have been reviewed. This paper describes an extraction method of the sea level change information in coastal districts by analyzing several actual remote sensing images. For understanding the current sea level rise, it is required to clarify the causes quantitatively among three causes of sea level changes, i.e., volumetric change of total ocean water on the earth, relative sea level change due to the crustal deformation, and change of irregularity of sea surface with ocean current. It is also required to compile maps in Asian or global scales. 13 refs., 6 figs.

This paper reports one example of flow analyses on a circulation test carried out in fiscal 1991 at the Hijiori hot dry rock experimental field (Yamagata Prefecture). A fluid circulation model was proposed to simulate an HDR circulation system for a shallow reservoir (at a depth of about 1800 m) demonstrated in the circulation test by using an electric circuit network (which expresses continuity impedance in resistance and fluid storage in capacitance). Storage capacity of the reservoir was estimated by deriving time constant of the system from data of time-based change in reservoir pressure associated with transition phenomena during the circulation test. The storage capacity was estimated separately by dividing change of storage in the reservoir by change in the reservoir pressure. To derive the storage in the reservoir, a method to calculate non-recovered flows in the circulation test was utilized. The results of evaluating the reservoir capacity in the shallow reservoir using the above two independent methods were found substantially consistent. 3 refs., 6 figs., 1 tab.

This paper reports pressure response analysis on wells piercing a high angle multi (HAM) fracture model. In this model which is defined on a three-dimensional space, a plurality of slanted fractures intersect with wells at high angles (however, intersection of fractures with each other is not considered). With respect to the pressure response analysis method using this model, the paper presents a basic differential equation on pressure drawdown and boundary conditions in the wells taking flows in the fractures pseudo-linear, as well as external boundary conditions in calculation regions (a reservoir spreads to an infinite distance, and its top and bottom are closed by non-water permeating beds). The paper also indicates that results of calculating a single vertical fracture model and a slanted fracture model by using a numerical computation program (MULFRAC) based on the above equations agree well respectively with the existing calculation results (calculations performed by Erlougher and Cinco et al). 5 refs., 6 figs.

The image processing technique (reported previously) developed for analyzing combustion in a diesel engine was applied to measuring flow and turbulent intensity in a high pressure spray. Copper vapor laser beam in a sheet form with a thickness of 0.2 mm was injected into the cross section of a spray center in a container. Photographs of the scattered lights of the beam is converted into digital values and analyzed using an image processing equipment. With the laser light emitting frequency set to 20 KHz at a maximum, the flow velocity is measured from changes in photographic image density in two subsequent photographs, and the turbulence intensity from changes in brightness intensity. As a result, it was clarified that the flow velocity and the turbulence intensity in the spray cross section increase with raising the spray pressure. Further discussions are being made on the measuring method, including changes in the image brightness associated with entrance and exit of spray particulates into the laser beam sheet, and effects of the laser beam sheet thickness on the measurements of the turbulence intensity. 6 refs., 6 figs.

This paper describes the seismic tomography analysis of underground structures using finite differential calculation (FDC) and a reciprocal principle which points out that a propagation path is constant even if a source and receiver are exchanged with each other. Tomography analysis generally determines a ray length across each underground cell structure by ray tracing method to modify each cell slowness (inverse of velocity). Travel time field was determined by FDC of eikonal equation among ray tracing methods, and a wave propagation path was determined by reciprocity of elastic wave to carry out inversion. In conventional methods, since a wave length is assumed to be infinitesimal by ray theory, false modified slowness structures frequently appears depending on the density of a ray. Wave propagates in a certain width, and is affected by environment. The slowness was thus modified on the basis of the wave propagation path with a certain width by using not ray-tracing but reciprocity. By this modification, false structures were hardly found under a fine grid, and several propagation paths could be considered. 6 refs., 9 figs.

An improved J-shaped blade, in which a J-shaped blade is combined with a small-size Savonius blade, has been developed, to further improve efficiency of an air turbine for wave power generator systems. A prototype model of stationary wave power generator has been developed using the improved blade, to confirm its power generation characteristics by tests in a water tank and small-scale ocean tests. The results are compared with the characteristics of the units with conventional blades. The air turbine unit with the improved blade shows an efficiency of 13 to 35%, which is higher by 10 to 20% than that of the turbine with a J-shaped blade and by 20 to 70% than that of the one with a Savonius blade, more noted at low speed of rotation. It is therefore considered that the turbine with the improved blade is suited for sea areas having a relatively low wave height. It is also considered that efficiency can be further enhanced, when one or more guide vanes are provided around the blade. 2 refs., 12 figs.

A field test was carried out in 1995 on a deep-seated geothermal investigation and reduction well WDR (in Kakkonda, Shizuku-ishi, Iwate Prefecture) by utilizing a multi-frequency array induction logging tool which is under development by NEDO. This paper reports results of analyzing the acquired data. With the WDR wells, an investigation has been conducted to a drilling depth of 330 m. Three frequencies in a range from 3 to 24 kHz provided relatively good data, but data with 42 kHz had poor quality that cannot be utilized for the analysis. Precise device calibration is difficult on data acquired from three array type vertical component magnetometers (the difficulty may be due to a signal line from a transmitter passing on the magnetometer side). Because of this difficulty, analysis using one-dimensional inversion program was performed by using ratio of the amplitude for each frequency and phase difference as input data. The analysis allowed to have derived a result that corresponds to the ground bed structure. 5 refs., 8 figs., 3 tabs.

Five cross sections were applied as a result of MT method investigations in addition to the results of conventional analyses at the Kakkonda geothermal area; three-dimensional resistivity distribution was made into a database by using the Kriging method which makes a matching with anisotropy of seismic center distribution in micro-earthquakes; and the database was compared with the data derived from surveys on the pilot survey well WD-1a and the side-truck well WD-1b thereof. As a result, it was found that the well WD 1b which encountered a water loss zone had the water loss zone exist in a region with relatively lower resistivity than in the well WD-1a which did not encounter a water loss zone. The region in which the water loss zone was encountered existed in a very steep slope region going from the high resistivity region in the west side toward the low resistivity region in the east side. This fact suggests a possibility that fractures have developed in this region with sharp slope in the resistivity in this area. Adding three-dimensional complementary function to the GEOBASE database by using a simple Kriging allowed the direction of anisotropy in spatial data to be freely and quickly decided. It was learned that this capability exhibits strong power in a mapping work in structures where such anisotropy as a geothermal zone is highly dominant. 5 refs., 8 figs., 2 tabs.

The impression which an illustrations in newspaper advertisements and wrapping paper give to human beings plays an important role in commodity sales. When we try to evaluate the comfort level which these illustrations give to human beings, 1/f fluctuation caused by the colour array can be considered as one important element. As a fundamental study of the method to evaluate such illustrations from the standpoint of a colour array, we have studied a method that measures the comfort level of round shaped four colours with conformity arranged on plain white paper. This system presupposes that the four colours exert a mutual influence of potential energy according to their arrangement. We have tried to define and evaluate this energy. The comfort level is measured using the calculation value of energy. For this study, we have used the above proposed system to compare 16 kinds of samples conforming to the above method calculating the value of energy with the results of a questionnaire answered by two or more groups of human beings. 9 refs., 6 figs., 1 tab.

With the aim of studying the fracture dynamics of environmentally assisted fractures in thin plates, we developed a new source simulation method of the zeroth-order symmetric (or S{sub 0}-) Lamb wave using the experimental overall-transfer function of the system. The transfer function was determined by the time-domain deconvolution of detected S{sub 0}-Lamb component by the artificial fracture source of a compression -type PZT element whose vibration kinetics was estimated by the iteration so that the S{sub o}-waveform detected. Hydrogen induced blistering was found to be caused by the succession of fast Mode-I fracture with source rise times from 0.6 to 1.0{mu}s. The crack volume estimated by the source simulation corresponded to that of fine blistering with an opening displacement of 5{mu}m. As the estimated fracture kinetics of hydrogen blistering coincide with those of delayed fracture of high tension low alloy steel under tensile loading, the kinetics of first and micro-fractures and blistering induced by hydrogen gas precipitation appears to be independent on the hydrogen solubility and strength of steels, the applied stresses and the orientation of cracks.

Records of seismic observation were analyzed for the purpose of proving the validity of antiseismic design for a prestressed concrete (PC) cable-stayed bridge. This bridge is a three span continuous PC cable-stayed bridge of 498 m in bridge length, and is constructed on alluvial soft ground. The seismometer used is a servo type accelerometer. The observed frequency and mode of seismic vibration are in good agreement with those in the analysis and hence the validity of modelling of the structure in designing was confirmed. It was also confirmed that the bending vibration and torsional vibration of the main girder are separated as designed. However, some points such as a large difference in the observed vibration and analysed vibration in the mode accompanying rotation of the base are listed as problems to be solved in antiseismic design. In order to investigate the attenuation constant of the upper structure, a seismic wave response analysis was performed and its results were compared with observed ones. When the attenuation constant is assumed to be 2%, agreement of data between analysis and observation is good, and it is considered that the attenuation constant of the upper structure only without the effects of attenuation of energy escape from the base and crack generation in concrete was about 2% in the observed earthquake (maximum acceleration on the ground: 51 Gal). 8 refs., 9 figs., 2 tabs.

The Beijing Shuidian Research Institute of Geophysical Surveying has performed ocean seismic exploration in the area where the Fujian Pingtan bridge was planned to be constructed. The elastic wave exploration device is of a multi-functional type. The device has functions of acquiring, processing and analyzing data in seismic exploration using the reflection method, and can visualize subsurface conditions at the same time as performing the exploration. The planned bridge building area spans over a sea area of about 3500 m long with water depths from several meters to 30 meters. The foundation bed consists of dacite lithologic tuff and granodiorite. The seal level varies from 4.0 m to 4.8 m between high and low tides. According to the result of other measurements, the elastic wave propagation velocities of the sea water were found from 1475 to 1485 m/s, and the elastic wave propagation velocities at the surface bed of the sea bottom were from 1550 to 1700 m/s. The exploration used a workboat which moves at a constant speed while maintaining the offset between a transmitting source and a receiving source constant, executing vibration transmitting, receiving and recording all on the sea. The result of the exploration revealed that neither obstacles such as sunken ships nor marks of occurrence of ocean bottom landslides were present. 1 ref., 5 figs.

The objective of this study is to analyze the crash characteristics of vehicles under the condition of real-world accidents. This paper pays attention to the differences in the crash characteristics of a vehicle colliding with a vehicle which is a different type. Vehicles on the market can be divided broadly into two vehicle structures, monocoque structure and frame structure. Monocoque structure is mainly used for passenger vehicles and frame structure is for recreational vehicles (RV). In recent years, RV has been a large seller on the market. So accidents between passenger vehicles and a RVs occur frequently. The analysis of experimental data and computer simulation, which is predicated on the experimental data, was carried out for this study. In the analysis of experimental data, barrier force data from the New Car Assessment Program (NCAP) were analyzed. The FE passenger vehicle model which is based on systematic validation tests was used for the computer simulation of car-to-car collisions. (author)

Although Ti: Sapphire expects of a possibility of being a light source much superior to a dye laser having been used as a wavelength variable laser for spectral analyses, it has a limitation that it does not oscillate directly in the visible and ultraviolet regions. In order to develop a light source that is synchronizable over ultraviolet-near infrared regions, by means of combining a Ti: Sapphire laser of a high peak power, comprising an oscillator and a multistage amplifier, with a non-linear frequency conversion method for harmonic generation and Raman conversion, a prototype Ti:Sapphire laser that is excited by YAG laser second harmonic, and that synchronizes with a prism was fabricated, and its operational characteristics were investigated. As a result, an output energy of 35.6 mJ at a maximum was obtained at a wavelength of 773 nm against an excitation energy of 129 mJ, a conversion efficiency of 38.2% was obtained against the absorption energy of the crystals, and a continuous synchronism was achieved over 750 to 900 nm. 4 refs., 9 figs., 1 tab.

This paper reports the result of a preliminary circulation test conducted in fiscal 1995 on a deep reservoir (at a depth of about 2200 m) in the Hijiori hot dry rock experimental field. One water injection well and two production wells were drilled to constitute a circulation loop, to which the circulation test was performed to investigate the flow characteristics thereof. The result revealed the following matters: total amount of injected water of 51500 m{sup 3} resulted in a total fluid recovery rate of about 40%; as a result of well stimulation given twice during the initial stage of the water injection, the continuity impedance in the vicinity of the injection well decreased largely (however, the continuity improvement upon the second attempt was considerably inferior to that from the first attempt); and increase in the water injection amount does not necessarily lead to increase in the production amount. The paper describes additionally that it is extremely difficult to interpret non-linearity between the injection and production amounts by using a model prepared previously with a main objective to analyze the Hijiori HDR circulation system. 1 ref., 9 figs., 1 tab.

This paper reports a method to detect reflected wave components contained in an elastic wave caused in association with well drilling. Measurement was made on an elastic wave caused in association with well drilling in an experimental field by using a triaxial elastic wave detector disposed in a measurement well. Analyzing the particle motion tracks in the derived elastic wave signals (to derive the main axial direction of a three-dimensional hologram) revealed that oscillation direction of the signals changes non-steadily by time centering around the S-wave oscillation direction. In addition, a sound source position was estimated during the drilling. Existence probability of the S-wave signal in the non-steady continuous signals was estimated by handling the particle motion tracks stochastically. In addition, this existence probability was used as a weighting function for a correlative analysis to detect a reflected wave from directly reaching wave components in the non-steady continuous signals. Thus, improvement in reliability of reflected wave detection was attempted. Effectiveness of this method was endorsed by the field data. 3 refs., 7 figs.

An examination was made by a model analysis on sensitivity and the like against a resistive anomalous body, in connection with an electromagnetic tomography system with surface earthquake sources and underground receiver arrangements. A resistivity model was of a three-dimensional structure, and built with a 5 ohm{center_dot}m low resistivity anomalous body assembled in a 100 ohm{center_dot}m homogeneous medium. As a result of the examination, it was shown that the size limitation of an analyzable anomalous body was 50{times}50{times}20m at a frequency of 8 to 10kHz and that a system with high precision in a high frequency range was necessary. The examination of effects under a shallow anomalous body revealed, for example, that the fluctuation of a low frequency response was large compared with a deep anomalous body and that, where a second anomalous body existed under it, the effect also appeared with a surface earthquake source positioned in the opposite side from the anomalous body. The examination of effects under the three dimensional structure revealed, for example, that a remarkable change appeared in the data with the change in the inclined angle of the transmission line against the strike of the anomalous body. 4 refs., 7 figs.

Acoustic streaming is generated by Reynolds stress in the sense of mean acoustic momentum flux in a sound field. In the case of an acoustic standing wave produced by an air column oscillation in a closed duct, the friction and the Reynolds stress in the resulting Stokes layer are the essentials of acoustic streaming generation in the vicinity of the duct wall. The thickness of the Stokes layer decreases with the oscillatory Reynolds number. The plane wave propagation in the duct is assumed for the case of high Reynolds number except for the thin Stokes layer adjacent to the duct wall. The velocity profiles of the streaming are estimated theoretically from the steady component of the second-order term of a perturbation expansion in which the first-order approximation is a sinusoidal oscillation of the air column with plane waves. The present paper describes theoretical analysis of the velocity profiles of the acoustic streaming in the Stokes layer by means of the matched asymptotic expansion method. The results obtained show the existence of reverse streaming in a very thin layer adjacent to the wall and the effects of thermal boundary conditions at the wall on the velocity profiles of acoustic streaming in the Stokes layer. 9 refs., 8 figs.

This paper describes the deformation and dynamic stability of circular arch subjected to follower forces in a submerged membrane type marine structure reinforced by arch frames. Governing equations for finite deformations of the circular arch subjected to follower forces are introduced using an embedded curve coordinate, which are formulated by applying Galerkin method. In addition, equations of motion due to small disturbances under given condition of loading are introduced. Based on these equations, dynamic stability of the arch is analyzed by means of Runnge-Kutta-Gill method, to clarify the relationship between disturbances and instability regions and the resulting phenomena. Near the boundary regions of stability, both amplitude and cycle of deformation are greatly affected by the amplitude of disturbances. The dynamic instability is governed by the inverse symmetry primary mode with minimum characteristic frequency which is specific for the circular arch. The dynamic stability has high parameter dependency, and the instability regions have a complicated shapes. Although flattened arch has a smaller static critical load, it provides the dynamic stability against the disturbance. 5 refs., 10 figs.

An analytical system with superposition of images which uses picture elements as a unit was developed to treat information obtained by remote sensing and other geographical information by superposing the images in order to extract the second information which expresses qualitatively and quantitatively the degree of slope disaster in the future, based on the first information about the damage caused by disaster and landform and geology. As necessary function for analytical system of the second information, precise correction of geometrical strain, superposition of images, visual reading treatment, and output of analytical result in map are listed and described respectively. Next, the detailed explanation of hardware and software of pilot system which used personal computer was given. The analytical procedure and result of land conditions around the landslide occurred at Nagano city in 1985 was shown. 3 refs., 1 fig., 1 tab.

This paper examines the dynamic characteristics on the model of the beam supported by one cable, the most simple type of cable-stayed bridge, with fundamental and important linear and nonlinear internal resonances from the experimental and analytical aspects. Vertical oscillation of the beam is able to cause parametric oscillation of the cable, so that dynamic phenomena which derive from internal resonance such as saturation of amplitude of vertical oscilation of the beam are observed experimentally. Based on the concept of local and global oscillation modes, a 3-DOF(degree of freedom) model is formulated considering the geometric nonlinearity of the cable. Then, a test of a small model, taking notice of linear compound of the cable and the beam as well as autoparametric compound by quadratic nonlinear terms, is conducted under vertical and horizontal harmonic excitations. After identifying the parameter of the model, the experimental value is compared with the analytical value. As a result, it is shown that both of them are highly consistent with each other. 16 refs., 9 figs., 2 tabs.

This paper introduces a refuse crushing apparatus to reduce for storage the volume of refuses produced on board a ship by crushing. Refuses to be crushed are solid wastes including solid combustible refuses such as paper, wood pieces, and cloths, non-combustible refuses such as empty cans, metals and glass, and refuses unsuitable for combustion, such as plastics and stylofoam. Crushing methods include impact system, compression system and shearing system. The shearing system shears and crushes refuses by using blades rotating at a low speed. The system has a wide range of crush ability and excellent versatility, generates low levels of dust, noise and vibration, and is suitable as a marine use refuse disposing apparatus. However, empty cans and PET bottles are more difficult of getting into cutting blades requiring a large amount of time for crushing. Therefore, it is more suitable to reduce volume of refuses by using a compressor or the like apparatuses, and then crush them by using a double-axial shearing crusher. Stylofoam causes its crushed pieces to be electrically charged and deposited onto the apparatus, hence it is more suitable to reduce the volume of refuses and make them brittle by heating, and then crush them by using the double-axial crusher. 2 figs.

Buckling and plastic collapse of upper decks and bottom outer plates of a hull results directly in longitudinal bending collapse of the hull. Therefore, discussions were given on analysis for pressure destruction strength of a detection control panel which assumes an upper deck and a bottom outer plate. Pressure destruction behavior of the panting panel is a complex phenomenon accompanying non-linearity and geometrical non-linearity of the materials. Its whole phenomenon may be analyzed by using the finite element method (FEM) as a principle, but the analysis is not efficient. Therefore, considerations were given in relation to modeling when using the FEM. The considerations were given on a panel attached with flat steel panting members with respect to the modeling scope which considers the buckling mode according to the aspect ratio of the panel partitioned by the deflection control members. If the local buckling mode of the panel is an even number wave mode in the longitudinal direction, a triple span model is required. A modeling scope for a case of being subjected to water pressure and in-plane compression was considered on a panel attached with angle-type steel members having non-symmetric cross section. In this case, a triple bay model is more preferable to reproduce the behavior under water pressure loading. 1 ref., 6 figs.

The relationship between coal properties and liquefaction or gasification characteristics was analyzed by using the analysis and test results and liquefaction characteristics in the coal data base. On liquefaction reaction, the close relation between an oil yield and coal constituent composition or a coal rank is well-known. Various multivariable regression analyses were conducted by using 6 factors as variables such as calorific value, volatile component, O/C and H/C atomic ratios, exinite+vitrinite content and vitrinite reflectance, and liquefaction characteristics as variate. On liquefaction characteristics, the oil yield of dehydrated and deashed coals, asphaltene yield, hydrogen consumption, produced water and gas quantities, and oil+asphaltene yield were predicted. The theoretical gasification efficiency of each specimen was calculated to evaluate the liquefaction reaction obtained. As a result, the oil yield increased with H/C atomic ratio, while the theoretical gasification efficiency increased with O/C atomic ratio. 5 figs., 1 tab.

The Hanshin/Awaji earthquake disaster caused extensive damage to many bridges of the Hanshin Expressway. N particular, falling-down of superstructures and other destructive damage occurred at Benten Kouku which located in downtown of Kobe. After the earthquake disaster, the continuous 19-span space frame bridge with lead rubber bearings which had approximate 565m bridge length was reconstructed in this region. It is the first trial in Japan to use large lead rubber bearings as an isolator or as a damper at the bottom of the steel pier for the purpose of reduction of seismic force acting on this bridge. As the lead rubber bearings, a spring member was used. In this study, by using jack with a raid releasing mechanism, monotonous loading tests loading statically at the bottom of the pier and rapid releasing tests deloading loads in a moment were carried out. Further, the simulation of the experiment was conducted on the analysis and the analytical model was established in comparison of the experimental data and the analytical data. Using this model, owing to carry out the seismic response analysis, more reliable analytical results were obtained. 22 refs., 24 figs., 3 tabs.

Formulation was made on a one-dimensional beam finite element which is effective in analyzing structural response of very large floating structures by modeling them on beams on an elastic foundation. This element allows strict solution of vibration response in the beams on the elastic foundation to be calculated efficiently for a case where mass and rigidity change in the longitudinal direction. This analysis method was used to analyze structural response of a large pontoon-type floating structure to investigate mass in the end part for the structural response and the effect of decay while passing the structure. With a pontoon-type floating structure, reduction in bends and bending stress in the end part of the floating structure is important in designing the structure. Reducing the mass in the end part is effective as a means to avoid resonance in these responses and reduce the responses. Increase in rigidity of a floating structure shifts the peak in quasi-static response to lower frequency side, and reduces response in resonance, hence it is advantageous for improving the response. Since incident waves decay while passing through the floating structure, response in the lower wave side decreases. The peak frequency in the quasi-static response also decreases at the end part of the structure in the upper wave side due to decay in wave force. 7 refs., 11 figs., 1 tab.

The paper introduces an RO unit (reverse osmotic membrane equipment) for producing water holding for the canned coffee drink processing line introduced to the Ibaraki plant of Tone Coca-Cola Bottling Co. The unit aims at reducing hardness components from city water and producing water holding for the coffee drink processing line. The capacity of the unit is 25m{sup 3}/h and the recovery rate is 80%. The unit is composed of a sand filter, an heat exchanger, a pre-filter, RO modules, a treated water tank, chemicals storage tanks, and an RO cleaning unit, which are all for pretreatment. The treated water, into which chlorine is injected, is sent through the existing activated carbon tower and micro filter to the processing line. The RO unit can remove at the same time ion and trihalomethane, pathogens, organic matters which are substances other than hardness components. The continued water bottling is possible with no need for the usual reproduction process, and the maintenance is easy. Because of the high hardness of the supplied raw water, acid is injected at the primary side of the unit for pH regulation to prevent scale deposition in the RO modules. The quality of the treated water well met the specifications. 2 figs., 2 tabs.

Described herein are the results of the FY1994 research program for analysis and evaluation for thin film solar cells. The study on quantitative analysis of hydrogen atoms in a plasma determines quantity of hydrogen atoms in the plasma of monosilane diluted with hydrogen. It is found, contrary to expectation, that quantity of hydrogen atoms in the plasma decreases as it is more diluted with hydrogen. The study on light-induced degradation of the thin chlorine-base amorphous silicon films confirms that the plasma CVD method with 20% of dichlorosilane gas added to monosilane gas produces the thin amorphous silicon film 3 times faster than the conventional method. The thin film has essentially the same defect density as the one prepared by the conventional method, showing good photoelectric characteristics. The thin film of chlorinated amorphous silicon has a 1 digit lower defect density than the conventional one of amorphous silicon, as revealed by the accelerated degradation test with irradiated laser light and the constant current method to determine saturated defect density. 3 figs.

Described herein are the results of the FY1994 research program for development of extra-high efficiency III-V compound semiconductor tandem solar cells. Heteroepitaxial structures of compound semiconductors, such as GaAs, on silicon substrates are analyzed and evaluated by EXAFS, Raman and RHEED for the initial stage of the film growth and heterointerfaces. The device capable of in-situ observation of the growing surface structures during the period of heteroepitaxial film growth is introduced, to investigate the effects of rise-up and initial growth conditions on defects. The effects of atomic hydrogen on growth of a GaAs film on a silicon substrate are investigated from photoluminescence and solar cell characteristics, to confirm the effects of reducing defects. Heteroepitaxial growth of InGaP, which has the optimum band width for forming multi-junction silicon solar cells, on a silicon substrate is investigated, to find that an interfacial buffer layer is necessary to form a good film. 2 figs.

The rare gas discharge gives a stable discharge and light emission characteristics at low temperature in comparison with the discharge of the vapor of such a metal as Hg. The present barrier for the commercialization of the color PDP lies in the lower level of its emission intensity and efficiency in comparison with that of CRT. In this report, an electron impact ionization coefficient in a gas mixture and an electron impact excitation coefficient for a XeIs {sub 4} level were analyzed using a Boltzmann equation by means of a steady state Townsend method using a drift tube. By comparing both, the elementary process in the gas mixture is investiagted to discuss the respective contributions for the effective ionization coefficient and the excitation coefficient. As a result, it was found that the ionization process in the He-Xe gas mixture could be described by the processes of direct ionization of Xe and He, and an indirect ionization (Penning effect) by an active helium. 37 refs., 12 figs.

The simple analysis method of persistent current induced in on-board superconducting coils was proposed for the vehicle of a superconducting magnetically-suspended train which is running in the magnetic field generated by armature coil current of a linear synchronous motor installed along a guideway, and the performance of the method is discussed through calculation based on typical models. As fluctuation of persistent current due to running was calculated with various parameter values under a normal running condition, fluctuation of persistent current induced was less then 1% of an initial magnetomotive force, having no adverse effect on the stability and reliability of superconducting magnets. Electromagnetic forces under a normal running condition could be predicted accurately enough by relatively easy-to-calculate constant current mode analysis. Double-layered armature coils were preferred to single-layered ones to enhance the stability of superconducting magnets by reducing fluctuation of persistent current. 10 refs., 8 figs., 1 tab.

Establishment of a simple and reasonable technique and its application to the metallic surface in addition to the nonmetallic surface in the room-temperature measurement using infrared picture equipment have been studied. It was found, as published in the previous paper, in the investigation of radiation temperature, radiosity coefficient, their wave-length dependence and the dispersiveness of these parameters about the surfaces of various kinds of material that the assumption of gray body approximation does not hold in the surfaces of metal and part of nonmetal. In the present work, applicability of pseudo-gray body approximation to the metal surface in a system surrounded by black body surfaces was studied in consideration of directivity of emissivity and reflectance while, in actual, a measuring angle of 15 degrees giving a small directivity effect was used based on experimental results. As in the previous paper, three kinds of sensors different in the detectable wave-length range were used to evaluate the radiation temperature, emissivity, radiosity coefficient, and their dispersiveness. The experimental results proved the applicability of pseudo-gray body approximation. 3 refs., 18 figs., 2 tabs.

A questionnaire investigation about the present situation, current problems and countermeasure to be discussed with by material technology groups in the eight chemical companies was carried out. It has become clear from the analysis of answers obtained that the roll of material group has been changing under the diminishing construction of new plant and the increased needs of stable and sustainable plant operation. The present major subjects of material groups, which are pointed out in the answers, are such new technological problems as the plant life estimation, the dissemination and handing down of material technology and the upbringing of technology successors. The countermeasures to meet those requirements made clear are such technology developments as a new monitoring system, preparation of database on material technology and closer cooperation with relatied associations. It is hoped for that the findings of this study would lead to further and more detailed indentification of common problems to be solved and development of practical countermeasures therefor.

In order to examine the aerodynamic characteristics of a supersonic axial flow turbofan realizing flight of Mach number of 2-5, the double linearization theory was applied to a three dimensional oscillation cascade accompanying a steady load in a supersonic axial flow condition and unsteady pneumatic force and aerodynamic unstability of oscillation were studied. Moreover, the values based on the strip theory and the three-dimensional theory were comparatively evaluated. Fundamental assumptions were such that the order of steady and unsteady perturbation satisfies the holding condition of the double linearization thory in a supersonic-and equi-entropy flow of non-viscous perfect gas. The numerical calculation assumed parabolic distributions of camber and thickness in the blade shape. As a result, the strip theory prediction agreed well with the value given by the three-dimensional theory in the steady blade-plane pressure difference and in the work of an unsteady pneumatic force, showing its validity. Among the steady load components of angle of attack, camber and thickness, the component of camber whose absolute value is large has the strongest effect on the total work. The distribution reduced in the angle of attack and camber from hub toward tip gives a large and stable flutter margin. 5 refs., 13 figs., 2 tabs.

A method for predicting the local heat transfer coefficient is presented for film condensation of vapor in a spirally grooved horizontal microfin-tube. Based on the flow observation study performed by the present authors, film flow model between fins in the annular flow regime is proposed. For the fin surface, laminar condensate film controlled by the combined effects of vapor shear and surface tension forces is analyzed. While, in the groove, thick condensate film driven by the vapor shear force is taken into consideration. A parameter which accounts for the transition from annular- to stratified flow regimes is also derived. The present and previous local heat transfer data for fluorocarbon refrigerants in the annular flow regime are found by the present numerical analysis to have a mean absolute deviation of 15.1 percent. 12 refs., 10 figs., 2 tabs.

During a refraction seismic survey conducted at a spot where a high-speed lava layer is supposedly concealed, the distribution of lava layer was estimated, and a composite analysis involving the vibration data received via hydrophones arranged in a bore hole was accomplished using a high-speed model based on an assumed geological section. The refraction survey centered on the bore hole and was accomplished using 250m-long traverse lines extending therefrom, one to the upstream and the other to the downstream of a river, producing a total length of 500m. The hydrophones were installed in the bore hole, and the measurement was carried out in an offset VSP-like observation pattern. In the analysis, the velocities obtained by the refraction survey and velocity logging were assigned to each layer on the basis of the assumed geological section for the construction of a velocity distribution model, which served as the early model for the repetition of calculation. Calculation was repeated with help of the said model, and a geological structure, capable of explaining the travel time data collected during the refraction survey and velocity logging, was successfully estimated. 1 ref., 5 figs.

A reliability analysis was performed on ultimate strength of a hull by introducing reliability engineerings into the idealized structural unit method. Elements developed under the present study were applied to a model of an actual structure to indicate that even an analysis requiring much time under the finite element method can be performed in a short time and at high accuracy when this method is used. Analysis acted with bending moment and shear force simultaneously was performed on a model used as a structure in experiments carried out by Nishihara, assuming pure bending moment and longitudinal strength during slamming. Then, a reliability analysis was conducted on the same model based on this analysis method to investigate the ultimate strength. In an analysis of an ultimate strength when bending and shearing that assume slamming act upon simultaneously, axial force in the hull side decreases as loading increases, wherein how the shearing force increases can be identified clearly. Although existence of initial bends reduces the strength, the effect of variance in the vicinity of the average value on the reliability is rather small, while the effect due to variance in yield stress is greater. 27 refs., 14 figs., 4 tabs.

A two-dimensional analysis was carried out on electric exploration data obtained by using the CSAMT method in the Itaya prospect in the southern part of the Tohoku region in Japan. Considerations were given on mine exploration targets. Gold produced in this area is contained in stockwork or vein deposited quartz in silicified hydrothermal breccia. Therefore, the exploration targets are silicified rocks that show high resistivity. The field investigation using the CSAMT method was conducted by installing a dipole source of about 1.9 km as a transmission source at a location about 6 km apart from the investigation area, and by measuring transmission currents from 8 to 10A and ten frequencies from 4 to 2048 Hz. The two-dimensional analysis was performed by using programs of a forward calculation that used a finite element method and of an inversion calculation that used a least-squares method. Analysis utilizing resistivity of the boring cores made minimizing RMS misfit possible. As a result, estimations were made on distribution of silicification and claying alteration from the detailed resistivity distribution around the Itaya mine. 5 ref., 8 figs.

A model analysis was used to investigate sensitivity of a two-dimensional structure on a resistivity anomalous body by using an electromagnetic tomography system. The resistivity model handled a three-dimensional structure. The model was prepared as a pseudo two-dimensional model in which a low resistivity anomalous body with 1 ohm-m was incorporated that has a basic length of 1000 m in the Y-direction in a homogenous medium having 100 ohm-m. As a result of the analysis, the following matters were elucidated: if a low resistivity anomalous body is present in a shallow subsurface, its impact starts appearing from lower frequencies than when the anomalous body exists only at a greater depth; if a high resistivity anomalous body exists, the detection sensitivity is lower than for the low resistivity anomalous body, but the analysis would be possible by using the phase because the phase has made a greater change; the source TxZ shows a change from lower frequencies than for the source TxX, and the amount of change is greater, hence the detection sensitivity on an anomalous body may be said higher with the source TxZ; however, for the anomalous body in shallow subsurface, the source TxX is more effective since it is not subjected to a too great impact at a greater depth. 5 refs., 7 figs.

Li2O-TeO2 glasses attract attention because of unique properties such as high density, high refractive index, large dielectric constants and high infrared transmittance. The short range structures of two samples of Li2O-TeO2 glasses (15:85 mol% Li2O-TeO2 and 25:75 mol% Li2O-TeO2) were investigated by X-ray diffraction technique. Interpretation of the obtained radial distribution functions was performed on the basis of the strength comparison method. The following conclusions were obtained: Two types of Te-O bond lengths of 0.18nm and 0.20nm are found in TeO4 tetragonal bipyramid. As network forming units, the TeO4 tetragonal bipyramids and TeO3 trigonal bipyramids are observed. The TeO4 tetragonal bipyramid units are transformed into the TeO3 trigonal bipyramids through the transient species of polyhedral with non-bridging oxygen atoms with increasing content of Li2O. The lone pair of Te atom does not contribute to the formation of the glass network. 17 refs., 6 figs., 2 tabs.

As a part of the studies on practical surface temperature measurement by infrared radiometer, some basic characteristics of an infrared radiometer were studied by using three kinds of sensors with different detectable wave lengths. Specimens allowable for gray body approximation such as mortar, graphite and carbon fiber composite material were tested at a practical ambient temperature of 293 K. As a result, the difference between a radiation temperature in consideration of reflection and that derived from an emissivity increased with a decrease in emissivity, and the deviation of an emissivity derived from a radiosity coefficient increased at 20 K or less in difference between a specimen surface temperature and ambient one. Each radiosity coefficient measured by each sensor also fairly agreed with each other. The deviation of a radiosity coefficient was relatively small indicating a good agreement between theoretical and experimental data, while the difference between emissivity and radiosity coefficient deviations decreased with an increase in specimen surface temperature. 3 refs., 10 figs., 1 tab.

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 aim is to develop a highly reliable device for detecting pathological developments deep inside the body by combining the pulse compression technique used in high performance radars and a quartz fiber. The project also aims to develop a system which, when compared with the conventional method, is capable of higher resolution at a short range and of reaching farther for the same resolution level. To be contrived for the development of a diagnostic catheter which combinedly uses the ultrasonic pulse compression and imaging technology and an optical picture system are a pulse signal reflection mirror for taking in ultrasonic picture data on the front and the sides in the lumen, an ultrasonic micromotor for rotating the mirror, and a high efficiency ultrasonic transducer similar in size to the waveguide for transmitting ultrasonic pulses to a quartz waveguide from outside the body and for receiving reflected signals. An effort is simultaneously exerted to make the diameter smaller of a quartz waveguide to be built in the catheter to provide a signal passage for the ultrasonic imaging system and the optical picture system for the realization of a catheter tip smaller and thinner as a whole. A study is made about a mechanical-electronic control system for easy luminal insertion. (NEDO)

An ultrasonic probe with its point fine is navigated in blood vessels and body cavities by 3-dimensional ultrasonic signals (with the oscillator driven by transmission from a catheter for position detection) for the acquisition of accurate 3-dimensional ultrasound images in a less invasive way. The transmission and reception circuits are provided with circuits for ultrasound tomographic images and for navigation. Trial units are fabricated and tested for transmission waveform and reception performance. The scanner is rotated for the acquisition of intravascular 3-dimensional radial images. The scanner rotating rate is set at 30 rps for the scanner performance not to be affected by heartbeat and the rate is controlled by the observation unit which changes voltage for the control. The 3-dimensional display software program, thanks to the navigation function of the external probe, detects the external probe position relative to the small-diameter probe for the construction of accurate 3-dimensional images. Specifications for a total system, which makes full use of a navigation function, are compiled, consisting of a small-diameter probe and a body surface real-time 3-dimensional display. (NEDO)

Attachment 4 of the FY 1998 report on development project of structural residence of the next generation describes the frame analysis system manual. NAPISOS is a program for analyzing static and dynamic responses of three-dimensional structures. The dynamic response is calculated by numerical integration in the time region. Dynamic load can handle dynamic exciting force, uniform seismic input and forced displacement at a node, and analyze linear elasticity and non-linear properties. The static load can handle nodal force, static seismic coefficient and forced displacement at a node, and analyze linear elasticity and non-linear properties. The static analysis also can perform analysis based on the time history response displacement method as the special case. The program implementation procedures fall into 4 general steps; first: inputting/processing of structural data, second: eigen value analysis or equivalent nodal force calculation, third: response calculation by direct integration, preparation of equivalent damping matrix or pre-stress analysis, and fourth: outputting the results. The input data related to control, structure and load are also described. (NEDO)

The Wasabizawa area is located near the boundary between Yuzawa city south of Akita pref. and Ogachi-machi, Ogachi-gun, Akita pref, having a range of 3.0km northeast-southwest and 2.5km northwest-southeast of Wasabizawa almost as a center. The area for survey and its circumference are national forests, and the east and a part of the south of the area are designated as the Kurikoma quasi-national park third type special region. From the geochemical temperature distribution, it can be assumed that geothermal fluids of around 300{degree}C exist in the deep underground of the Kaminotai-Wasabizawa-Akinomiya area. From the distribution of density basements, the block structure of the basement can be estimated. Around the boundary of the ridge/sedimentation region of this density basement, fractures develop and the formation of reservoir structure is expected from the comparison with the result of the well survey. In the blowout test, obtained were 284.3{degree}C and 83.05 kgf/cm{sup 2} at a depth of 1,300m. In the geothermal system, it is assumed that reservoir structures of geothermal fluids develop in the deep underground of the central part of the area. The heat source to the geothermal system is supposed to be the magma reservoir remaining in Takamatsudake volcanic rocks. 110 refs., 177 figs., 105 tabs.

Unstructure models were developed for a mixed culture where one microorganism assimilates the metabolite produced by another microorganism The model system was a mixed culture using Lactobacillus delbrueckii and Ralstonia erthroprop where the former assimilates glucose and produces lactic acid, and the latter assimilates lactate and produce poly {beta}-hydroxy butyrate (PHB). Performance improvement is shown for the mixed culture over a single culture for chemostat using the model developed. Since the optimal dissolved oxygen (DO) concentration is different for each microorganism, we developed another model which takes into account the effect of DO concentration on the dynamic behavior. Then the optimal DO concentration is obtained for chemostat. Moreover, we developed another model which takes into account NH{sub 3} concentration on the cell grown and PHB production by R. eutropha. Then the optimal time-profile for NH{sub 3} concentration is derived using the maximum principle. It is found that high Phba production could be attained even if NH{sub 3} concentration is not controlled if initial NH{sub 3} concentration is appropriately selected. (author)

For understanding of fundamental chemical reactions under a highly non equilibrium condition which is quite often used in plasma processing, the relevant atomic and molecular processes must be clarified. In this study, an analysis of the transition process to the excited state of an oxygen molecule induced by electron collisions in the oxygen plasma has been carried out. First, the electron density distribution in an oxygen molecule has been calculated using the extended Huckel molecular orbital method. Then, the electron potential energy distribution in the transition process to the excited state has been estimated. The electron behavior has been calculated using the estimated unidimensional electron potential energy distribution and unsteady quantum mechanics. As a result, the transition process to the excited state of an oxygen molecule induced by electron collisions and its conditions have been clarified qualitatively. 9 refs., 9 figs.

The result is reported of a TDEM method-based survey for oil exploration conducted in the Yoneyama district, Niigata Prefecture. The survey covered the southern part of the sedimentary basin in the prefecture, known for the poor quality of the seismic prospecting data that had been recorded. The purpose of the TDEM method-assisted survey was to probe the high-resistivity volcanic rock structure and low-resistivity sedimentary layer, and to know their details. The obtained data were subjected to interpretation by use of the 1D inversion method. A 4000m-deep level was subjected to interpretation, 34 data were inputted, and the early model consisted of 20 layers. As the result, it was found that there was a high-resistivity layer ranging from the ground surface down to a depth of approximately 500m, that a low-resistivity layer 2500-3000m in thickness lay thereunder, and that the lowest layer had a high resistivity of approximately 100 Ohm m. By comparing these data with the geological structure, structures were disclosed corresponding to the rock bed depth, Ukawa syncline, Ishiguro anticline, and Yoneyama mountain mass. 3 refs., 10 figs., 1 tab.

The paper studied output characteristics of photovoltaic modules different in installation conditions on the basis of the energy balance state. In the study, an energy balance equation was constructed for insolation intensity, heat losses from PV surface/back, and output, in order to calculate cell temperatures in each installation condition. A comparative study was made between calculated results and measured data obtained on the top of the school building. The results indicated the following: The thickness of thermal boundary layer became approximately 27mm at insolation intensity of 800 W/m{sup 2}, ambient air temperature of 25degC, and wind velocity of 0.5m/s. When widening air gap from 20mm to 40mm, the cell temperature decreased 4degC, and the output increased 1.6%. In the case of installing photovoltaic modules on the roof considering the relation between the air gap in the heat balance state and the thickness of thermal boundary layer, heat from PV back was released outside the air gap if widening the air gap to more than 30-40mm. The type with a heat insulating material on the panel back decreased in output from other types. 5 refs., 7 figs., 4 tabs.

Examination was made on wind conditions, power generating characteristics, and the reliability of a system by analyzing the operation record of the wind power generation equipment which was installed at Hiraizumi-cho, Nishi-Iwai gun, Iwate prefecture and at Misaki-cho, Miura-shi, Kanagawa prefecture. The equipment at Hiraizumi had a rated output of 490 kW, and at Miura 400 kW. The period of the examination was from April, 1998 through February, 1999, the items for data collection being the generator output, generated energy, average wind velocity, record of abnormality occurrence, and maximum wind velocity. At Hiraizumi, annual average utilization rate was 12.9%; annual average operation rate, 49.9%; average wind velocity, 4.6 m/s; and maximum wind velocity of the period, 31 m/s. At Miura, annual average utilization rate was 16.5%; annual average operation rate, 77.0%; and average wind velocity, 5.0 m/s. The utilization rate is desirably 17%. The top three abnormalities were drop in AC control voltage, actuation of main shaft brake and eddy current/actuation of open phase relay, accounting for 83.3% of the total abnormalities at Hiraizumi, while they were unbalance in current, grid drop and automatic unwinding of cable, accounting for 74.5% at Miura.

In order to discuss effectiveness of physical exploration in the Sakonishi prospect in the Hida area, physical exploration was carried out by utilizing bored wells. This area contains the Kamioka mine, one of the major base metal mines in Japan, where electrical exploration has been attempted several times in the past. No effective results have been obtained, however, because specific resistance contrast between mine beds and base rocks is too small, and the topography is too steep making site workability inferior. As part of the investigations on geological structures over wide areas, electrical logging (specific resistance and natural potential) was performed in fiscal 1995 and 1996 by utilizing the boreholes. Induced polarization logging was also conducted on the same boreholes. A traverse line on the ground with a length of 600 m and boreholes were used to execute specific resistance tomography. Clear extraction was possible on a fault structure which is thought related with limestone distribution and mine bed creation. However, it was not possible to identify upward continuity of zinc ores expected in the exploration. Because of not large a specific resistance contrast between zinc ores and base rocks, it is difficult to find mine bed locations only from the information on the specific resistance. 5 refs., 5 figs., 1 tab.

We measured the changes of heart rate in order to analyze the drivers` stress while they tried high speed lane-change on the stationary driving simulator. We concluded that the reasons of the chances were mainly dependent on the following two items. (1) mental pressure caused by the coming task of lane-change, (2) mental disturbance by the task to keep the vehicle inside the lane. By using the mental pressure and disturbance, we could evaluate the stability of the vehicles in lane-change maneuver. 3 refs., 11 figs.

Photosynthetic activity of plants is an important factor to assess the micrometeorological effect of plant canopy or to estimate the influence of circumstances such as water stress. Light illumination induces fluorescence from a leaf or suspension of chloroplasts. The red chlorophyll fluorescence had been used to determine the process of the electron transportation in photosynthetic reaction. The fluorescence source other than chlorophyll is not announced sufficiently, but is supposed to be useful to determine the contents of the substance corresponding to physiological response of plants. We developed a fluorescence imaging apparatus to observe spectrum and distribution of laser induced fluorescence from a leaf. Pulsed UV-laser (Nd:YAG) induced blue-green fluorescence and red chlorophyll fluorescence from a green leaf. The pulse modulated measuring light and CCD with image-intensifier (ICCD) enable to detect the fluorescence from plants under illumination. The laser induced fluorescence (LIF) spectra were investigated to estimate the chlorophyll contents in leaves of rice. During the greening course of dark grown etiolated rice leaves, chlorophyll contents were determined using the extraction of leaves and steady state LIF spectra were measured. As a result, the ratio of fluorescent intensity between blue-green and red peaks (F460/F740 and F510/F740) decreased in proportion to alteration of chlorophyll contents respectively. These fluorescence intensity ratios perform more precise estimation of higher chlorophyll contents of leaves than reported red chlorophyll fluorescence intensity ratio (F690/E740). (author)

Full Text Available Purpose: The aim of this research was to record and the evolution of the winter paralympic games and sports since 1976 until 2010. The history of the Winter Paralympic Games is relatively recent compared to that one of the Olympic Games. The first Games were held in 1976 in Ornskoldsvik, Sweden and the most recent, 38 years later in 2014, in Sochi, Russia. This article will examine the Winter Paralympic Games up until the ones in 2010 in Vancouver, Canada. During these years, there have been many changes in relation to the Games itself, the governing body of the Paralympic Movement, the sports’ facilities, the sports involved and sports’ categories. The motivation for writing this paper was the need to record and gather all of these items in one paper. Gathering information for the Winter Paralympic Games will be an important theoretical background. This information will create a database for the structure of the governing body of the Paralympic Games, for the organization of the Games [Local Organizing Committee (LOC, venues and equipment], for the evolution of the Winter Paralympic Sports and the categories of the athletes, as well as the evolution of the athletes’ and sports’ participation. Material : The research material that was used was mainly from the bibliography and records of the International Paralympic Committee (IPC, from the Official Post Games Reports and the Internet, while the research method that was used was descriptive. Moreover, the use of diagrams will depict the distribution of the participation of athletes and countries in each Games. Results : The participation of countries grew continuously and steadily from 16 to 44, during the years of 1976 to 2010 respectively. Regarding the athletes’ participation, starting in the first Games with 198 athletes, they reached the number of 502 in the 2010 Vancouver Winter Paralympic Games. The participation percentages of the athletes coming from Europe constituted the bulk

Full Text Available The article explores the issue on the perception of the concept “national security” areas, models and methods of its maintenance by the population. The author uses materials of the sociological survey conducted by the Laboratory of problems of increasing the efficiency of state and municipal management of the South-Russian Institute of Management – branch of the Russian Presidential Academy of National Economy and Public Administration. The survey was carried out with the participation of leading experts in various aspects of national security, representing 27 Russian higher educational institutions and research centers in Moscow, Astrakhan, Barnaul, Belgorod, Dushanbe, Krasnodar, Nizhny Novgorod, Omsk, Pyatigorsk, Rostov-on-Don, Saint Petersburg, Syktyvkar, Sochi, Ufa. It is noted that as a priority political governance model that implements the basic concept of national security, respondents identified a democratic model. Most respondents believe that a unified security model in the Russian regions is ineffective, and such model should be developed taking into account the specificity of each subject. The study showed that the public’s attention to the issue of national security is not sustainable, as determined by situational factors. It is proved that the motives of anxiety formed in the Russian public mind are not sustainable, and situational. Respondents see the economic cooperation more effective incentive to maintain national interests than by force. Estimation of the population of the priority issues of security shows that most respondents appreciate the organization of work to ensure the safety and anti-terrorism security in the sphere of national relations. The findings give grounds to assert that the focus of public attention to the problem of national security does not yet occupy the leading positions. To a greater extent, respondents focused on the issues of public safety, reducing threats and risks in their daily lives

Interference between fan blades in a turbo-fan engine and struts also being a structural member may induce fan blade oscillation and noise, thereby presenting itself as an obstacle in development efforts. Therefore, this paper proposes a method to analyze unsteady aerodynamic responses of mistuned cascade with varied stagger angles, as well as elucidates the effects of the mistuned stagger angles by means of numerical calculations. The non-steady pressure distribution on the blades is affected by the mistuning, but its extent varies with phase difference in the incoming viscid wake. As its result, the non-steady lift acting on the blades varies with the mistuning. In this case, it is possible to reduce the size of the non-steady lift depending on the conditions of blade arrangement and incoming phase difference. The size of the non-steady lift under the same phase incoming condition has a close correlation with the steady lift. It was shown that the quasi-steady analysis is effective in the case of the same phase condition. 8 refs., 14 figs., 1 tab.

Tetrahydrofuran (THF) solubility and structure of the butylated products of meso-carbon microbeads (MCMB) were studied experimentally. In experiment, MCMB-A and MCMB-B obtained from two kinds of coal-tar pitch were used as specimens. MCMBs were butylated by BZ method using dibutylzinc-butyl iodide and KT method using K-butyl iodide-THF, and the butylated products were successfully obtained. The butylated products were investigated through THF solubility test, {sup 13}C-NMR measurement and gel permeation chromatography (GPC) measurement. As the experimental result, a BZ method produced the butylated products at a yield of nearly 170%, while a KT method produced them at a yield of nearly 130%. The THF solubility was estimated to be 89-97%. As the study result of molecular weight distributions by GPC measurement of solvent solubles, the molecular weight of raw material MCMB was estimated to be 590-770 in terms of polystyrene. 6 refs., 2 figs., 1 tab.

This paper reports on a precise numerical analysis of operating characteristics of the push-pull parametric transformer of orthogonal-core type (proposed by the authors in the preceding papers) made in consideration of both the iron loss of its magnetic core and the copper loss of its windings. A model of magnetic circuit in the core is presented, which involves magnetic reluctances representing saturation characteristics of the core and magnetic inductances representing effects produced by hysteresis. Use is made of the function that expresses the saturation characteristics by a twenty-first power series of magnetic flux, the coefficient of each term being determined by use of experimental data on a specified sample of the magnetic core. Furthermore, recourse is had to the circuit simulator SPICE in order to analyze the operating characteristics of the transformer. Comparing results of the present analysis with experimental results, the following are noted: first, both output voltages and currents of windings of the transformer under the condition of parametric oscillation are calculated with sufficient accuracy; second, the present analysis is capable of evaluating the conversion efficiency of electric power and input power factor of the transformer, and of providing more accurate values of both voltage and current in the case of the maximum output under loading conditions as compared with the analyses so far presented. 8 refs., 11 figs., 2 tabs.

Long-term operation of a photovoltaic power generation system installed in a private residence in Osaka in 1992 is evaluated. Since the sale of power by back flow was approved five years ago, it has been working continuously without troubles. The evaluation covers the array output coefficient, inverter performance, system output coefficient, and power generation and sale track records. The findings obtained are mentioned below. Regular seasonal changes are observed in the array output coefficient, high in winter and low in summer, but the variation is smaller in amorphous arrays than in polycrystalline arrays. The monthly level of inverter performance is almost in all months higher than 0.90 specified for standard operation. The overall system output coefficient is 0.749, which is higher than the average value in NEDO`s field test business report. A total of 7852kWh has been generated since the system started operation five years ago, of which 3787kWh or 48% has been sold. 3 refs., 9 figs., 5 tabs.

Heat and mass transfer characteristics within a reforming catalyst bed have been analytically investigated. A numerical analysis was carried out in a two-dimensional steady-state model of reforming catalyst layer. Reforming tube was filled with catalyst and the tube wall was uniformly heated, a mixture of steam and methane was reformed through the catalyst bed. Predicted temperature, formed gas composition, methane conversion rate, and heat transfer coefficient distributions in the catalyst layer showed good agreement with experimental data. The effects of space velocity, steam carbon molar ratio, and wall temperature on the heat transfer coefficient were analytically presented. From temperature and composition distributions simulated by two-dimensional analysis, the effects of these factors above mentioned and diffusion on the transport phenomena were qualitatively predicted.

In the case where sources and receivers are not distributed on a 2-D plane, seismic tomography inversion was studied. In tomography experiments, the existing wells are generally used. In such case, sources and receivers are frequently not distributed on a 2-D plane. The 2.5-D analysis method including 2-D structure and 3-D ray-tracing was thus developed. This method is featured by less memory necessary for ray-tracing calculation, and the same algorithm for velocity determination as 2-D analysis method. In previous methods, since analysis is generally carried out by projecting sources and receivers on a certain assumed 2-D plane, it can derive correct results in the case of constant velocity and straight ray, however, in the other case, it derives incorrect results. Application of 3-D tomography requires a large amount of memory, and falls into poor convergence because of various parameters. The 2.5-D analysis method can avoid these demerits. This analysis method was applied to the data obtained in Ogiri area, Kagoshima prefecture. 5 refs., 3 figs., 2 tabs.

In production of Si raw material, as electron beam melting and ingot production are combined, C, P, Ca and Al are removed by evaporation, while Fe and Ti by solidifying segregation. As the basic technology of continuous casting for substrate production, a drop coagulation method for Si melt is under investigation which is more advantageous in unidirectional solidification and cell conversion efficiency than conventional methods. The cost and future of single crystal Si and polycrystal Si were compared on the basis of document survey. Every institute commonly uses FZ substrates to produce single crystal Si cells, and SiO2 for surface passivation. New cell structure, hetero-structure, thin cell, crystalline defect and lifetime are under investigation for ultrahigh-efficiency solar cells. The technology trend was also surveyed through academic societies and conferences. 5 tabs.

An elasto-plasticity stress analysis was performed on reinforcement using a wing wall made of post-placed concrete as an anti-earthquake reinforcement method for ferro-concrete structures. The analytical values were compared with experimental values, and discussions were given on reasonability of the analytic method. Wing walls made of post-placed concrete were inserted into a three-layered single-spanned model of a reinforced framework made of reinforced mortar (the wing walls being three kinds comprising 1/4 span portion in the first layer, and 1/4 portions in the first and second layers). With the columns loaded and retained with an axial force of 3 tf, a horizontal force was applied from one direction under an assumption that the force forms a uniform distribution. The analysis model was permuted with a wire material having one nodal point and three degrees of freedom as has been reported in the previous paper. The model was divided into the wing wall and the column, and the wing wall portion was permuted into a brace having pins at both ends so that the brace has the withstand strength equivalent to that of the wing wall. A tri-linear type or a bi-linear type was hypothesized for restoring force characteristics of each portion. According to the analytical result, the analytical values agreed relatively well with the experimental values in the load-deformation relationship and fracture conditions, verifying the reasonability of the analytical hypothesis. 5 refs., 5 figs., 3 tabs.

A 3-year (FY 1999-FY 2002) research plan titled 'The basic research on a high-sensitivity gene diagnosis system for cancer by free DNA in blood' was worked out and the study was started. The plan is as follows. It is confirmed that the quantitative study of peripheral blood free DNA becomes the information useful for early finding-out of cancer carriers, and the reliability and limits are made clear. By widely searching for gene anomaly of cancer itself, it is confirmed that it is possible to diagnose anomaly in quality of genes in peripheral blood free DNA. For those purposes, technology is developed for high-sensitively detecting/quantifying free DNA of peripheral blood, etc. and further detecting anomaly of the genes comprehensively, and the medical/engineering joint research is conducted to realize the early diagnosis of cancer. In FY 1999, the following studies were started using detection/analysis technology mainly by polymerase chain reaction (PCR): development of high-sensitivity detection technology of free DNA, development of high-sensitivity detection technology of gene anomaly, study of the cancer-origin gene anomaly, etc. (NEDO)

To reduce the exhaust emissions and fuel consumption of direct-injection diesel engines, it is essential to optimize the fuel injection equipment closely related to combustion and emission characteristics. In this study, three-dimensional computation has been applied to investigate the effects of the injection nozzle specifications (e.g., sac volume, round shape at the inlet of the nozzle hole) and needle tip deviation on internal flow characteristics. The computational results revealed that the effects of the nozzle specifications and needle tip deviation with a smaller needle lift on internal flow characteristics and a general approach to optimize the injection nozzle specifications were obtained. 3 refs., 10 figs., 1 tab.

We have fabricated a 64 embedded microelectrode-array substrate using semiconductor technology to investigate the biological signal processing in brain by using cultured neural networks of fetal rat neocortex in vitro. We analyzed temporal and spatial neural networks patterns cultured on electrode-array substrate and attempted to examine the network structure constituted by neurons and the propagating patterns of electrical activity induced by the electric stimulus. In the experiments, each microelectrode size was 30 {mu}m squared and 150{mu} m spaced. For stimulation, one of the electrodes was selected and current pulses were applied through an isolated circuit. After the network was cultured in about 50 days, responses of neurons to electric stimulus were monitored extracellularly through 64-channel electrode array. Data recorded at each electrode consist of several spike trains generated by different cells. Therefore, these trains were separated by using wavelet transform and template matching for each electrode. We referred the temporal patterns of generated spikes for each electrode to as `spike sequences`. Next, we compared With the spike sequences among multichannel data and visualized the Cultured neural networks structure by identifying the directions of propagations and cell connections. 15 refs., 9 figs.

For the purpose of developing the technology required for the biotechnology industry, a study was made on proteins having ligand recognition function, and the FY 1998 results were reported. In the technology development of a system for various/diversified syntheses of functional molecules, a system was designed/trially manufactured which enables the simultaneous synthesis of various biological/functional substances (compound library) at high-efficiency. In the development of the structure analysis system of ligand recognized proteins, a high-efficient biopolymer analysis system was developed which is based on TOF (time-of-flight) mass spectrometer and analyzes proteins produced by recombined genes quickly and precisely. In the R and D of functional molecules using ligand recognized proteins, the cloning was successfully made of the human estrogen receptor gene hER {alpha}, which is composed of 1,785 bp, from MCF-7-BOS. Further, the bioassay system for estrogen-like substances using MCF-7 cells was established. (NEDO)

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

Although the next-generation phosphoric acid fuel cell has nearly reached its practical application stage as far as technology is concerned, its diffusion is yet to come due to lack of data about its cost efficiency and reliability. Under the circumstances, the goal now is to collect and analyze various data obtained in the above-named project which was started in fiscal 1997 for the compilation of data useful for full-scale diffusion in the future so that a foundation may be built for the overall popularization of the fuel cell. In this fiscal year, assessment and analysis have been conducted at 15 test sites now in presence. At the second plant of the Semboku LNG Terminals where approximately 17,000 hours have elapsed since the test began, the cell has operated for more than 16,000 hours in total. The Mycal Bore Sanda has established the longest uninterrupted operation record of 6,500. As for power generation efficiency, a town gas 13A-fueled system exhibits approximately 40% operating smoothly at a high overall efficiency of not less than 90%. (NEDO)

Fluids in geothermal reservoirs are not necessarily in the single phase but is occasionally in the gas-liquid double phase. This study aims to collect fundamental knowledge about the analysis of tracer responses in a gas-liquid two-phase flow, with special attention paid to the movement of substances in the liquid-phase portion of the two-phase flow. A tracer test is conducted in a glass bead-filled layer, and then it is found that the conventional mixture-diffusion model fails to explain the outcome of the test conducted using the said very simple apparatus. The failure is attributed to the coexistence of high-saturation and low-saturation layers throughout the glass bead-filled layer, and a mathematical model is formulated, which is a development from the two-fractured-layer (TFL) model. It turns out that the mathematical model excellently describes the test result that the mixture-diffusion model fails to explain. In the numerical solution of this problem, the validity is confirmed of the use of the SIMPLEX method for the estimation of the effect of the numerical dispersion term of the third-order accurate finite upstream difference method, and of unknown parameters. 31 refs., 7 figs., 1 tab.

For the purpose of reducing energy consumption and CO2 discharge in a cement plant in Indonesia, R and D was conducted on new clinker cooling system, high performance kiln combustion system, and technology for steady kiln operation and control, with the fiscal 1999 results reported. In the research on the optimum clinker cooling system, a new type clinker cooling system (CCS) was developed in which air beams are applied only to stationary grate rows, in an air beam type clinker cooling system where cooling air is fed to each block, with grate plates used as the air duct. This year, in an actual machine testing equipment (capacity 2,500 t/d), the whole heat recuperation area was modified for the CCS, with the operation started since February, 1999, aiming at the optimal clinker cooling effect and high heat recovery efficiency. The heat quantity for the entire system showed a decrease of 60 kcal/kg in the heat consumption rate through CCS modification, kiln burner adjustment, etc. So long as the demonstration plant is concerned, design of a new type burner and study/design for the kiln stabilization were nearly completed.

This paper describes the achievements in fiscal 1992 in the field tests on fuel cell power generation systems. The three locations subjected to the present analysis are all installed with 50-kW systems, whereas power generation efficiency of around 35% such as 35.3, 34.2 and 34.6% was obtained when the systems were operated at the rated output. When the load gets to below a certain load band (about 30 kW), the power generation efficiency decreases proportionately with the load. The overall efficiency including heat supply was 77.8, 70.7 and 80.3% respectively at about the rated output, showing a trend that the higher the thermal efficiency, the higher the overall efficiency. The case of generating both electric power and heat simultaneously has higher efficiency than the case of heat supply alone. The contribution rate of the fuel cell as a base load was 2.8, 4.6 and 13.6%, respectively. The system with as high value as 13.6% takes a power load following type operation mode, in which power is generated during a time band with large load during weekdays, and no power is generated at nighttime and in holidays when load is smaller, playing a role of peak responding power supply. Only one trouble has occurred in an auxiliary generator in the heat recovery system. (NEDO)

Borehole N11-KN-1 was digged and investigated for clarifying the geothermal structure of the Kuwanosawa area, with attention fully paid to the existing survey results. The hole is inclined, 1,802.30m deep in total, with a casing pipe installed down to the 1,101.76m level. Temperature was measured and electrical logging was performed at levels 410m, 1,110m, and 1,802.23m while the hole walls were still exposed bear. The maximum temperature of 161 degrees C was observed at the hole bottom, and the product of permeability - layer thickness transmission coefficient was described by 3.72 to 4.75 times 10{sup -1} darcy.m. The geothermal structures in presence in the south-western part of the survey area and along the Wasabizawa fault were made clear, and it was found that there exists no high-temperature water system in the vicinity of borehole N11-NK-1. As tasks for the future, it was proposed that a geothermal survey of the south-eastern part which includes borehole N57-YO-2 and a geochemical survey of fluids including hot spring water and surface be conducted.

The geothermal development promotion survey was conducted in the Akinomiya area, Ogachi county, Akita prefecture, and the FY 1998 results were summed up. In the surface survey, geology/electromagnetism/precision gravity survey was made as supplementary survey, and re-analysis of 3D models was made. In the well survey, three wells of N10-AY-6 to N10-AY-8 were drilled to conduct the core examination, temperature/pressure logging, sampler logging, short-term jetting test, etc. Also conducted were the reservoir evaluation, environmental effect survey, etc. by pressure monitoring and water level observation. The results of the comprehensive analysis predict the following. In the Akinomiya area, there exists heat source in deep parts around Mt. Yamabushi-dake and Mt. Takamatsu-dake; Being given heat from this heat source, rocks, ground water and volcanic gas react on each other to form geothermal fluids. It is presumed that high temperature geothermal reservoirs exist in the east of the area. Moreover, the pressure distribution indicates that the Akinomiya reservoir and Wasabizawa reservoir can be a chain hydraulically. On the other hand, the west of the area is the low temperature and heat conductive area, and therefore, there seem to be no high temperature fluids there. (NEDO)

This paper describes the distribution of Curie point depth and its characteristics determined from the spectral analysis of magnetic anomaly data in East and Southeast Asia. It also describes relationships between the Curie point depth and the other geophysical information such as topography, heat flow data and tectonics. The Curie point depths are shallower than about 10 km at volcanic and geothermal areas, between 15 and 25 km at island arcs and back arc rifts, deeper than 20 km at continents, and deeper than 30 km at trenches. The Curie point depth (Dc) estimated from the heat flow data can be expressed by Dc=k{theta}c/q where k is thermal conductivity, q is heat flow, and {theta}c is Curie point. Based on the Curie point depths obtained from Curie point depth analysis in the cross section of northeast Japan and the averaged values of heat flow at individual points, they are distributed along a line of k{theta}c=1500[Wm{sup -1}]. Values of k{theta}c are small near the axis of Japan trench and large in the northeast Japan. It is considered that local anomalies can not be grasped from the spectral analysis. 21 refs., 3 figs.

The radiant tube heating system has been widely applied to the furnaces which require isolation of the heating atmosphere from the combustion atmosphere. However, the conventional system has a short life and it is difficult to reduce NO{sub x} emission when it is used at a high furnace temperature under high combustion load, because the fuel is burned in a small space. In order to solve this problem, we have studied the cause of radiant tube life depends on the uniformity of the temperature distribution along the radiant tube. We have developed a new burner using a two-stage combustion method with exhaust gas self-recirculation. As a result, the file of the new system has been increased by a factor of two or more, and NO{sub x} emission has been reduced by 20 % from previous levels. This paper presents an outline of the elastic-plastic creep analysis and the new burner, and describes the effect of its use on system life. (author)

For geothermal development in the Musadake region, Shibetsu-gun, Hokkaido, structural boring was carried out and boreholes were inspected. In the structural boring survey, borehole N11-MD-3 was drilled as deep as 2,001.18 m, and borehole N11-MD-4 2001.44 m. Performed or tested for each of the two boreholes were temperature logging, electrical logging, temperature recovery, reinjection, core cutting examination, and so forth. The result of the temperature logging shows that temperature rise is slower at levels deeper than 1280 m in borehole N11-MD-3, with the maximum temperature marking 274 degrees C, and, in borehole N11-MD-4, the maximum temperature is 198 degrees C. No reinjection test is carried out because the ground pressure is too high to allow the replacement of the borehole content with fresh water. Analysis results lead to a conclusion that the hot fluid in this region originates in fossil seawater and in meteoric water, the latter arriving after a long-term permeation process, heated by thermal conduction to 270 degrees C or higher. It is inferred that the geothermal fluid flows in a fissure in the vicinity of the Musadake/Mt. Shitabanupuri fault and a fault orthogonally crossing the said fault for the formation of a high-temperature geothermal storage. (NEDO)

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

In this study, a method for robust estimation of parameters of the space influence function model, which was possible to become unstable, was investigated by applying a principal component method. In order to carry out the robust estimation of parameters without the effect of multicollinearity, regression coefficients of principal components with small eigenvalue and with small single-correlation with dependent variables were required to forced to be zero in the estimation method by principal component. Through the case study using the real urban lattice data, the conventional method was compared with the principal component method. As a result, the latter method realized the excellent sabilization of spatial distribution patterns of estimation parameters and the simple interpretation of parameters. It also improved reliability since 95% confidence interval of the estimated value became smaller. This method was found to be effective as a basic measure to acheve the stability of parameters. 10 refs., 7 figs.

Natural convection heat transfer and flow structure in an anisotropic porous medium of square cavity saturated with Boussinesq fluid has been studied analytically and numerically. Based on asymptotic analysis three distinctive regimes are found depending upon the magnitude of permeability ratio K. In the vicinity of K=1 the average Nusselt number and fluid velocity are scaled with (KRa){sup 1/2} when either K or the Rayleigh number Ra is varied. In the limit of K {yields} 0 the heat transfer across the cavity approaches to the conductive state, and the convecting velocity, which is primarily in the vertical direction, is scaled with KRa. In the other end of spectrum, namely K {yields} {infinity}, the average Nusselt number and the convecting velocity are scaled with Ra and independent of K. The asymptotic results are verified with two-dimensional numerical calculations. The ranges of K of the respective regimes are also determined based on the numerical results. 12 refs., 12 figs.

During the winter period at the Black Sea Coast of Caucasus often there are the synoptic conditions leading to occurrence of the dangerous phenomena of weather: «northeast», ice-storms, strong rains, etc. The Department of Meteorology (Moscow State University) throughout 8 years spends regular measurements on the basis of Southern Department of Institute of Oenology of the Russian Academy of Sciences in July and February. They include automatically measurements with the time resolution of 5 minutes in three points characterizing landscape or region (coast, steppe plain, top of the Markothsky ridge), measurements of flux of solar radiation, measurements an atmospheric precipitation in 8 points, which remoteness from each other - 2-3 km. The saved up material has allowed to reveal some features of a meteorological mode of coast. But an overall objective of measurements - an estimation of quality of the numerical forecast by means of «meso scale» models (for example - model WRF). The first of numerical experiments by WRF model were leaded in 2007 year and were devoted reproduction of a meteorological mode of the Black Sea coast. The second phase of experiments has been directed on reproduction the storm phenomena (Novorossiysk nord-ost). For estimation of the modeling data was choused area witch limited by coordinates 44,1 - 44,75 (latitude) and 37,6 - 39 (longitude). Estimations are spent for the basic meteorological parameters - for pressure, temperature, speed of a wind. As earlier it was marked, 8 meteorological stations are located in this territory. Their values are accepted for the standard. Errors are calculated for February 2005, 2006, 2008, 2011 years, because in these periods was marked a strong winds. As the

coast is very high. It is proved by recent events in 1991, 2002, 2010 and 2012. Possibly, it will increase in the future, as well as number of high and destructive floods. This tendency is caused by strengthening of climatic and synoptic instability in the region and by the human activity in the watersheds and floodplains development (for example huge constructions for the Olympic Winter Games 2014 near Sochi). But this tendency statistically isn't significant yet. Decrease of flood risks will be promoted by optimization of system of hydrometeorological monitoring; detailed studying of factors and characteristics of the floods, including flood dynamic modeling and hazard zonation; development of effective methods of the forecast and the prevention of floods; increasing in channel capacity; population resettlement from especially dangerous areas. The scientific basis for these measures is created by authors within large-scale researches on a grant of the Government of the Russian Federation No. 11.G34.31.0007.

Landslide hazard assessment of slopes of Sochi was performed along the railway between the cities Tuapse and Adler (total length 103 km). The railway passes through the territory with active development of hazardous geological processes such as landslides, rock falls and debris-flows. By the beginning of 2016, 36 landslide sites were discovered along the railway (total length 34 km), 48 rock-fall sites (length 31 km), and 5 debris-flow sites (length 0.14 km). In recent years the intensification of deformations was observed. For instance, during previous 10 years (1996¬¬-2005) 28 sudden deformations occurred due to slope processes, which caused interruptions in traffic. And in the present decade (2006-2015), 72 deformations were recorded. High landslide activity and economic loss determined the necessity of complex investigations of engineering geological conditions of landslides development and causes of its intensification. The protection strategy development was needed to minimize negative consequences. Thus, the investigations of landslide situation along the railway "Tuapse - Adler" included the categorization of landslide sites by level of hazard, with risk assessment based on numerical criteria. Preliminary evaluation of landslide hazard for the railway was conducted via the analysis of archived engineering-geological documents. 13 of 36 landslide sites (total length 13 km) were selected, reflecting the variety and peculiarities of landslide displacements on slopes (both active and inactive sites). Visual field observations of landslide slopes using drone "DJI Phantom 4" were completed during the second stage of this investigation. High-resolution photographs of landslide cirques, cracks, scarp walls, vegetation features were obtained via drone, which would have been impossible to obtain from the ground in conditions of dense subtropical vegetation cover. Possible approaches to the landslide activity and hazard assessment were evaluated: slope stability

Combined heat transfer characteristics are obtained numerically for three-dimensional natural convection and thermal radiation in a long and wide vertical porous layer with a hexagonal honeycomb core. The porous layer is assumed to be both homogeneous and isotropic. The pure Darcy law for the fluid flow and Rosseland`s approximation for the radiation are employed. The numerical methodology is based on an algebraic coordinate transformation technique and the transformed governing equations are solved using the SIMPLE algorithm. The effect of radiation on the beat transfer characteristics is investigated in a wide range of radiation numbers and temperature ratios, for two Darcy-Rayleigh number values (Ra*=100, 1000), and for a fixed aspect ratio of H/L=1. The results are presented in the form of combined and convection heat transfer coefficients, and are compared with the corresponding values for pure natural convection. 7 refs., 12 figs., 1 tab.

For the contribution to elucidation of the geothermal structure in the Wasabizawa area, Akita Prefecture, survey by the paleomagnetic measurement and fracture system measurement was conducted of the borehole cores and specimens of outcrop granite obtained from boreholes of N6-WZ-3 and N6-WZ-4. In the survey, the following were carried out: measurement of the core fracture system of N6-WZ-3 (102-1,505m) and N6-WZ-4 (507-1,556m), paleomagnetic measurement of 9 outcrop granite specimens and 16 core specimens, and k/Ar age determination of 3 outcrop granite specimens. As a result of the paleomagnetic measurement of outcrop granite, the magnetization azimuth of the schistose granodiorite distributed in Kuwanosawa was regarded as almost NS. The measured magnetization azimuth of the core specimen obtained from the same rock mass was also made NS-based, and measurement of the fracture in the neighborhood was made. As a result, it was found out that the NNW system was dominant in dikes and that there was the NE system in most of the small geothermal channels. The fracture system of well tended to develop around the boundary between granite and metamorphic rock, and it was thought that this part could be a reservoir if temperature conditions are prepared.

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

This project is intended for environment friendly and pollution-free rinsing by using an ultra critical fluid of CO2 being an atmospheric constituent. It also has a purpose of establishing a new rinsing method implemented by an ultra precision component machine and device using such features possessed by the ultra critical fluid as high permeability and disinfecting activities. It is further intended of developing, fabricating, and practically using a rinsing equipment that makes possible precision rinsing of mechanical, electronic, optical and aeronautical components. Using the results of experiments performed in the previous year as the base, discussions were given on the relationship between the two aspects of the hardware aspect such as equipment configuration and piping of the rinsing equipment and the software aspect such as operating conditions and procedures and the rising effect. As a result, a new rinsing equipment of solvent circulation type was proposed. The basic design software for the specific equipment was completed, and an experimental equipment was designed and fabricated under the clean specifications. The performance evaluation and verification experiments were finished in the end of fiscal 1998, and collection of fundamental data has begun. With regard to the rinsing evaluation method, qualitative and quantitative analyses were performed on the rinsing by using a surface shape measuring microscope and the infrared spectroscopy. (NEDO)

The aim is to develop and widely diffuse a cleaning, sterilizing, and disinfecting system (chemicals and device) which is nearer to the best. A safety-conscious diluting/mixing technology was developed by which acid and sodium hypochlorite were mixed without generating any noxious gas. Using this technology, a mixing tube was developed, capable of homogeneously diluting chemicals in raw water and mixing them homogeneously. How the dilution and mixing occurred in the mixing tube was measured by an electric conductivity meter for evaluation, data on the state of diluting of the solution were plotted in a graphic chart for study, a comprehensive deliberation was made of performance, cost, etc., and then a device was experimentally constructed. A concentration level detecting sensor section and a metering pump were developed. The pH adjustment and disinfecting effect were assessed using various acids, and then it was found that the acetic acid was the most suitable in view of safeness, disinfecting effect, stability, and ease of adjustment. Based on the result of a comprehensive technical survey, a system was designed suitable for artificial dialysis, food processing, and cleaning and disinfecting of endoscopes. A prototype was built, and the development effort progressed to reach a level where a prototype was built and subjected to a field test. (NEDO)

The effort is to develop technologies of conducting highly sensitive, uninterrupted observation of metabolism in the brain by use of the {sup 13}C-MRS unit, for which some carbon chain compounds (glucose, amino acids, etc.), which assume an important part in metabolism, are labelled by a stable isotope {sup 13}C and then administered to living things. A multi-slice HSQC (heteronuclear single quantum coherence) method is developed for the achievement of sensitivity enhanced 16 folds, excellent compound isolating capability, and high localizing capability, and these contribute to the specification of an optimum pulse sequence. A double tuning coil is developed for transmission, and a 6-channel multi-surface coil for reception, these two providing a 3-fold increase in detection probe sensitivity. The nonlinear least-square method is applied for the processing of spectral data, which enables excellent isolation of compounds. It also enables the generation of an inclined magnetic field quick to rise and of a sequence high in amplitude/phase accuracy. New methods are developed for the synthesis of {sup 13}C-labelled glucose, dopa, glutamine, glutamic acid, and GABA (gamma-aminobutyric acid) which are expected to be useful in brain metabolism measurement, and the products are administered to animals for evaluation.

Geological structure analysis maps and lineament maps were prepared on the north-eastern area and parts of the ancillary areas thereof by analyzing radar images of a 1 to 200,000 scale. With regard to the geological structures, analyses were performed by using as the original data the north look radar images for the three special geothermal areas to have prepared the geological structure analysis maps. The analysis of the radar images identified ground bed boundary lines in more detail than in the existing geological maps, and new discoveries were made available on faults. The lineament maps were compiled by implanting into respectively corresponding topographic maps the 24 N-S lineament maps made by the west look radar images for the whole surveyed areas, and the 16 E-W lineament maps made by the north look radar images for the special geothermal areas. Based on the clarity and characteristics deciphered on the images, the lineaments were classified into the major, minor, and subtle lineaments, which were indicated on the lineament maps. The lineaments were digitized by positions of the edge points, and the histograms and statistical tables were prepared by computer processing. (NEDO)

As a part of the field test project for diffusing PV power generation into public facilities generally, evaluation and analysis were made on the collected data from 105 sites installed during fiscal 1993-1996. Analysis of operation characteristics was made by using parameters obtained by developing a basic equation for every component. 94% of all the sites fell under the total solar irradiation of 3.0- 4.5kWh/m{sup 2}/D. 83% of those fell under the equivalent array operation time of 2.5-4.0h/D. 70% of those fell under the equivalent system operation time of 2.5-3.5h/D. 72% of those fell under the system operation time of 9.0-12.0h/D. 78% of those fell under the effective inverter efficiency of 0.84- 0.96. 68% of those fell under the inverter load factor of 0.25-0.35. 85% of those fell under the array performance ratio of 0.7-1.0. 83% of those fell under the system performance ratio of 0.6-0.9. The generation cost decreased from 270yen/kWh in 1993 to 100yen/kWh in 1996 because reduction of an installation cost largely contributed to reduction of the total cost. (NEDO)

For the contribution to elucidation of the geothermal structure in the Haneyama area, Oita Prefecture, the paper carried out the drilling of structural boring exploration wells, N6-HN-1 (1,605m) and N6-HN-2 (1,402m), and the well exploration. In the well exploration, the following were conducted: measurement of earth temperature, temperature recovery test, electrical log, simple water injection test, core/cutting observation, core test, powder X-ray diffraction analysis, physical property test, measurement of homogenization temperature of fluid inclusion, etc. In the temperature log and temperature recovery test, the terminal temperature at a 1,600m depth of N6-HN-1 well and at a 1,400m depth of N6-HN-2 well was 139.6 degrees C and 26.2 degrees C, respectively. The homogenization temperature of fluid inclusion was relatively higher, +70 degrees C to +100 degrees C, than that in the results of the temperature log, but was on the side of lower temperature, -30 degrees C to -100 degrees C, in a comparison with the saturated boiling curve of the earth surface and ground water level. Namely, it was thought that around the N6-HN-1 well, there used to exist the high temperature fluid of 250 degrees C or higher at the peak period of geothermal activities, but there only existed the geothermal water of approximately 140 degrees C at the present time.

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.

Tests and researches have been performed with the objectives to establish an evaluation technology for load leveling effect by using a small photovoltaic power generation system for residential use, to clarify the effectiveness of the system as a discrete power supply source through demonstration operation, and furthermore to achieve optimization of designs of the small photovoltaic power generation system for residential use. This paper summarizes the achievements in fiscal 1997. The current fiscal year has performed the continued collection of data of the demonstration operation, and analysis and evaluation on the photovoltaic power generation characteristics and the house load characteristics. According to the data analysis result for fiscals 1995 through 1997, it was shown that, although the photovoltaic power generation system for residential use does not contribute much to load leveling in a house, it contributes to load leveling in the distribution line on the whole or a case as large as a grid. In addition, according to the survey on users who have installed the photovoltaic power generation system, it was indicated that the consciousness of electric power and energy conservation has heightened. The capacity of a photovoltaic power generation system for residential use is 3 kW for a standard type of home, which can take care of more than 60% of the house load. It was concluded that, if a storage battery of small capacity is accommodated, the system is effective for reduction of momentary peak load, enhancement of the power quality, and supply of power at a disaster.

For the purpose of achieving the target of reduction in CO2 regarded as substance causing global warming which was agreed at COP3, the study has been made since FY 1993 on 'the development of high performance industrial furnaces (regenerative combustion furnace using heat storage type burner for realization of high temperature air combustion).' By applying the good results obtained, a field test project for introduction of high performance industrial furnace has been implemented for three years (FY 1998 - FY 2000) to confirm the actual performance, reliability, etc. Collection/arrangement were made mainly of the data obtained in this field test project for the introduction of high performance industrial furnaces in each fiscal year (1998, 1999 and 2000), and verification/evaluation and arrangement were made. In this R and D, energy conservation was achieved at a rate of more than 30% of the target. Also about NOx, the result was obtained that the NOx by energy saving can be reduced 50% in almost all kinds of furnace if adding the reduction amount in emission amount and the reduction amount by high temperature air combustion. About the quality, the good result was obtained. Downsizing was conducted in approximately 10 examples. (NEDO)

Analyses and evaluations were given on heating furnaces and heat treatment furnaces used in the Japanese steel and iron industry to calculate amounts of energy and CO2 that could be reduced by introducing a new furnace. The analyses have derived factors affecting thermal efficiency of the heating furnaces by using regression analysis. Discussions were given on a high-temperature air combustion system and a stored heat combustion system as new furnace technologies. As a result, it was disclosed that the current fuel consumption could be reduced to about 40% to 80% only by performing air pre-heating ideally and suppressing heat loss from furnace walls. This concept is sufficiently payable in terms of economy. It was also revealed that fuel consumption could be reduced to about 12% to 36% and CO2 discharge could be reduced in proportion with reduction in the fuel consumption, if ideal preheating can be carried out on materials to be heated. Furthermore, a result was obtained that the present thermal efficiency of 26.86% in nonferrous industries such as for copper and aluminum could be increased up to 53.37%. 10 refs., 19 figs., 1 tab.

This paper summarizes the achievements in fiscal 1996. The current fiscal year has performed collection of data of the demonstration operation, checked the consistency in photovoltaic power generation characteristics, and housing and distribution line load characteristics, and the results were mounted on the database. The demonstration operation data were used to analyze and evaluate the facility utilization rate in the photovoltaic power generation, photovoltaic power generation dependence of the house load, load rate, and peak load reduction rate. As a result, it was found that not much of the peak load reduction effect by the photovoltaic power generation was recognized because the house load is related mainly on lighting load. However, as seen from the distribution line load, the peak load reduction was recognized when the house load and the commercial and industrial load are mixed, whereas it was revealed that the reduction effect is worth evaluation.

The 3-D flow field relative to a rotating paddle blade is acquired by synchronizing LDV measurements with the output of a shaft-mounted encoder. This makes it possible to capture the impeller stream velocity field, including the details of the discharge flow region behind the blades. Mean velocities ensemble-averaged between a specific impeller blade pair (over 90deg) show the extent of periodicity and the passage and structure of the discharge flow region. Pumping capacities are determined at both sides of impeller and tip of impeller, and it is shown that the radial jet is a consequence of fluid entrainment into the discharge flow region. Mean velocities taken in a rotating frame of reference reveal a significant periodic variation near the impeller than those taken in a fixed frame. 13 refs., 12 figs., 1 tab.

Research and development has been performed with the objectives to establish an evaluation technology for load leveling effect by using a small photovoltaic power generation system for residential use, to clarify the effectiveness of the system as a discrete power supply source through demonstration operation, and furthermore to achieve optimization of the small photovoltaic power generation system for residential use. This paper summarizes the achievements in fiscal 1995. With the demonstration operation in the current fiscal year, through-the-year data have been accumulated for the first time since the start of the demonstration operation, and were mounted on the load leveling database. As a result of analyzing the demonstration operation data, the following points were revealed: regarding the housing load, the lighting load is the main factor both in summer and winter; the effect of reducing the peak load by photovoltaic power generation is recognized at about 60% as maximum, but the substantial effect has large variation, hence stochastic; and the reverse current becomes the main factor during daytime, not necessarily leading to improvement of the housing load characteristics in the aspect of load rate. According to the surveys on the energy demand trends up to the year 2030, the power supply configuration, and introduction cost, it was revealed that the photovoltaic power generation can be sufficiently expected as a power supply to handle the peak load.

For the purpose of achieving the target of reduction in CO2 regarded as substance causing global warming which was agreed at COP3, the study has been made since FY 1993 on 'the development of high performance industrial furnaces (regenerative combustion furnace using heat storage type burner for realization of high temperature air combustion).' By applying the good results obtained, a field test project for introduction of high performance industrial furnace has been implemented for three years (FY 1998 - FY 2000) to confirm the actual performance, reliability, etc. Collection/arrangement were made mainly of the data obtained in this field test project for the introduction of high performance industrial furnaces in each fiscal year (1998, 1999 and 2000), and verification/evaluation and arrangement were made. In this R and D, energy conservation was achieved at a rate of more than 30% of the target. Also about NOx, the result was obtained that the NOx by energy saving can be reduced 50% in almost all kinds of furnace if adding the reduction amount in emission amount and the reduction amount by high temperature air combustion. About the quality, the good result was obtained. Downsizing was conducted in approximately 10 examples. (NEDO)

The purpose of this survey is to extract by using scenario analyses the unreliable factors having great influence on change in the Japanese power supply configurations, and verify how the unreliability of these factors would affect the future structures and what the resultant ratio of the power mixes would be in the future. The survey is also intended to verify, through a series of work of calculating how much CO2 emission quantity would be changed in the stage of the year 2012 in each power supply configuration, whether or not the approach by using the scenario analyses will provide information sufficiently reasonable to judge policies to realize reduction in CO2 emission around the electric power business. Although including many hypotheses and vagueness, the trial calculation subjected to each scenario prepared presently suggested that it is not possible to accomplish the target of reducing 9% from the 1990 emission level only by the single efforts inside Japan. This result shows the same contents and directionality that are shown by the results of a large number of surveys. However, the result has created a common recognition among the participants that {sup t}here is a possibility that some kind of effective countermeasures could be discovered{sup .} (NEDO)

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

With an objective to promote capital investments that have been fallen because of the recession in Japan, the Petroleum Department of the Agency of Natural Resources and Energy has decided to take the following measures limited to one year for application. The measures consist of the taxation system for high-level energy saving investment promotion and the taxation system for small business machine investment promotion. In the former system, facilities that are effective for promoting rationalization and serving for environment preservation are admitted a special depreciation of 30% (36% for small business) on acquired prices or a tax deduction of 7% (8.4% for small business). Tax deduction of 7% (8.4%) is granted on leased assets. However, machineries are subject to a requirement of the price to be higher than 2 million yen (2.7 million yen in leasing). As a result, petroleum product shipping facilities are also covered by the taxation measures. The latter system, which is intended to promote investments by small business corporations, admits a special depreciation of 30% and a tax deduction of 7% for machineries acquired at prices above 2 million yen. Electronic computers and facsimile machines are also subjected to the taxation measures if their prices are higher than one million yen.

The project aims at energy saving and CO2 emission reduction for a clinker cooling system (CCS), and a demonstration test was conducted at a demonstration cement plant in Indonesia. The plant started operation using the new CCS aiming for the enhancement of cooling and heat recovery efficiency. The actually achieved heat recovery efficiency attributable to the adoption of the new CCS was 60.8% against the target of 68%, this meaning an improvement of 8% over the value recorded prior to the new CCS adoption. As for increase in recovered heat due to heat recovery efficiency improvement of the CCS itself, it was 31kcal/kg-clinker. The heat reduction rate throughout the system thanks to the new CCS was 40kcal/kg-clinker. The kiln secondary air temperature increased for improved burner combustion performance for a rise of the clinker burning degree to 12kcal/kg in terms of calorie, and thus a reduction of 52kcal/kg-clinker in total was achieved. No mechanical trouble was reported with the new CCS. Investigations were conducted into cement supply/demand and technological trends in Indonesia, Vietnam, and China. Learnings from the investigation of German cement making technologies were fully utilized in the designing of the new system. (NEDO)

In this study, the stability of annular leakage-flow-induced vibrations was investigated theoretically and experimentally for a translationally and rotationally coupled two-degree-of-freedom system. The critical flow rate was both theoretically and experimentally obtained as a function of the passage increment ratio and the eccentricity of the passage. A good agreement between the theoretical and experimental results was obtained. It was discovered both theoretically and from the experiments that instability will occur in the case of a divergent passage: the eccentricity of the passage lowers the stability of the systems.

The field tests on photovoltaic power generation systems for public facilities have begun in fiscal 1992 by NEDO. The systems including those under construction are installed in 116 sites. Analyses were given on 75 sites which have been operated up to fiscal 1996. Analyses of the operation characteristics were performed by using performance parameters derived by developing the basic expressions into each configuration element. For the insolation on slanted surface, the range from 3.0 to 4.5 kWh/m{sup 2}/D accounts for 65% of the total insolation. For the equivalent array operation time, the range from 2.5 to 4.0 h/D accounted for 81%. For the equivalent system operation time, the range from 9.0 to 12.0 h/D accounted for 85%. The range for inverter active efficiency from 0.84 to 0.96 accounted for 79%. The inverter load rate was accounted for 88% by 0.20 to 0.35. The output coefficient was accounted for 82% by 0.7 to 1.0 in the array, and 87% by 0.6 to 0.9 in the system. The power generation cost has decreased to 200 yen per kwh in fiscal 1995 from 340 yen per kwh in fiscal 1992, largely contributed by reduced installation cost. (NEDO)

This paper reports an image processing analysis of combustion for a high-pressure direct injection diesel engine on the effects of air swirl and injection pressure upon combustion in the diesel engine. The paper summarizes a method to derive gas flow and turbulence strengths, and turbulent flow mixing velocity. The method derives these parameters by detecting movement of brightness unevenness on two flame photographs through utilizing the mutual correlative coefficients of image concentrations. Five types of combustion systems having different injection pressures, injection devices, and swirl ratios were used for the experiment. The result may be summarized as follows: variation in the average value of the turbulent flow mixing velocities due to difference in the swirl ratio is small in the initial phase of diffusion combustion; the difference is smaller in the case of high swirl ratio than in the case of low swirl ratio after the latter stage of the injection; the average value is larger with the higher the injection pressure during the initial stage of the combustion; after termination of the injection, the value is larger in the low pressure injection; and these trends agree with the trend in the time-based change in heat generation rates measured simultaneously. 6 refs., 14 figs., 2 tabs.

From among researches on hydrogen manufacturing technologies using thermo-chemistry in the Sunshine Project, discussions were given on equipment materials, with the second-stage reaction in the iodine system cycle as the object. This paper describes achievements in fiscal 1979. The reaction produces MgO, I{sub 2} and O{sub 2} from Mg(IO{sub 3}){sub 2}. Corrosion tests were performed by using test pieces made of Ni alloy, iron-Ni-Cr alloy, Ti alloy, Zr alloy, Nb and Ta. These materials are thought to have excellent corrosion resistance in high temperature gaseous phase composed of iodine, oxygen and water. Corrosion tests were carried out also by using sheet formed test pieces of 24 kinds of alloys and six kinds of commercially available non-ferrous metallic materials in different temperatures and atmospheres, mainly the iodine plus oxygen plus H{sub 2}O mixed gas atmosphere at 600 degrees C. The corrosion resistance of the tested materials can be divided into three ranks. Materials having relatively good resistance were Ni-50Cr alloy and Co group alloy. Materials having good corrosion resistance are very little affected by water content. The higher the temperature, the more the metal corrosivity has increased. Preliminary discussions were given on pipe formability in materials having good corrosion resistance as the equipment piping materials. Their mechanical properties were also tested. This paper also describes corrosion resistance tests under heat transferring condition by using pipe-formed test pieces. (NEDO)

With an objective of using practically the coal hydrogasification technology (the ARCH process), developmental research has been performed on important elementary technologies using different experimental devices. This paper summarizes the achievements in fiscal 1999. In the research by using a small testing apparatus, the Taiheiyo coal was used to have performed demonstration operation on the replacement natural maximized case, the heat efficiency maximized case, and the BTX maximized case. As a result, the three cases were found nearly as anticipated in the simulation, whereas the replacement natural gas maximized case has achieved the targeted whole coal conversion rate of 60% or more. However, the BTX maximized case presented a value lower than the targeted BTX yield of 12%. In the developmental research on the injector, the injector having been fabricated for the hot model test was given another combustion test, where the focal temperature of 1,200 degree C or higher was derived. The hot model test has verified the non-agglomeration performance of coal by using as parameters the focal temperatures, coal cross sectional area loads, coal types, and injectors. It was verified that the Taiheiyo and Shin Mu coals do not agglomerate excessively. (NEDO)

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

In order to heighten the grade by the present mobile wireless telegraphy system, through the experimentation and research on both data transmission and error correction methods, both data and facsimile transmission were confirmed to be possible together with the following result: In the character transmission by a CPU connection and other encoded transmissions in which even an error by one bit considerably influences the contents of data, 1200bps, as able to be widened in service area, is profitable. While the data transmission in the mobile wireless telegraphy generates many errors due to phasing and noise along the propagation route. To attenuate those errors, error correction encoding is effectively applied with a correction method to be selected by kind of data. Further the 150MHz band, as more largely influenced by urban noise than the 400MHz band, narrows service area in the urban district. While the mobile wireless telegraphy is restricted in frequency band region. 12 refs., 26 figs., 9 tabs.

The basic data are collected by the experiments, in order to optimize the {sup 13}C-MRS analyzer for non-invasion type brain metabolism measurement. The tests are conducted for normal aged volunteers and volunteer patients of, e.g., dementia as the subjects. Each subject is orally dosed with glucose marked with {sup 13}C at the 1-site, and the metabolized {sup 13}C glucose signals from two points in the back of the head are observed as the MR spectra for a total of 3 hours. The time-series data of the {sup 13}C glutamic acid and glutamine signals are analyzed, to determine metabolism speed of the TCA circuits, among others, which provides important information for understanding the brain cell functions. It is 0.33{mu}mol/g/minute as the average of the 5 subjects of normal aged volunteers, which is on a level with that of the young volunteers. On the other hand, it is 0.26{mu}mol/g/minute as the average of the 4 subjects of volunteer patients of dementia, although there is no difference of statistical significance between these values. These results, therefore, suggest that the patients of dementia tend to have deteriorated brain metabolism than the healthy persons. (NEDO)

The R and D project has been implemented for novel high-performance forming machines (HPFMs) which handle slurry-based stock materials, in order to impart diversified functions to a wide range of ceramic-based materials covering from traditional to fine ceramic materials, and improve their productivity. For slip casting which uses traditional slurry stock materials, electricity is passed through the work by installing electrodes in each section, to control growth speed and composition of the layers, which are inconceivable by the conventional method for each section. For casting alumina slurry as the fine ceramic-based material, the electrophoretic techniques are also applied, in an attempt to form complex shapes at high efficiency, and to control the inclined structures and compositions/structures at specific sections. For development of the machines on a trial basis for traditional materials, reduction of weight and increasing thickness of the bottom side are attempted for hand-washing bowls, leading to weight reduction of 25% at the maximum. For fine ceramic-based materials, the forming systems are developed, on a trial basis, for fine pipes and sheets. (NEDO)

It is for customers of high-voltage power of less than 500kW, where load management is less extensive than that in larger users, for initial consulting on improvement of load factor (recommendation of heat storage contracts). It is to be installed on the spot to display the load curves, to allow the expert visiting the site to issue initial proposals immediately. It displays `daily demands by time zone` instead of `monthly power consumption` previously provided, and makes the graph of demands by time zone. It is designed to be compact, light, and easily and safely handled. The field test results indicate that the system can be sufficiently practical with the major performance items. 4 figs., 1 tab.

This paper explains fiscal 1997 results of the development of technologies for characteristic analysis of superconducting magnetic bearings (SMB), the development aimed at putting a 10 MWh high temperature superconducting flywheel power storage system to practical use. Following fiscal 1996, calculation programs were prepared for a load capacity and bearing constant (spring constant, damping constant) on an axial type SMB, with validity of the program examined through comparison with experimental values. A finite element method was applied to a complex magnetic field by a magnet arrangement devised for the purpose of improving load capacity, dividing a superconductor into divided sections so that the effect of a complex magnetic field distribution could be reflected, determining the magnetization generating in each divided section by using a two-dimensional Bean model, and developing a method for calculating load capacity of each divided section by a magnetic moment method. A program was completed for calculating the load capacity and bearing constant of the entire bearing in the axial type SMB.

At the Ensham open-cut mine in Australia, an investigational survey was conducted of a new rehabilitation technology which can contribute also to securing CO sink with the aim of preventing global warming, and the FY 2000 results were summed up. In the survey, the surface soil, sand silt layer, brown rock layer, gray sandstone layer and coal seam were moved from open pits, the goaf was embanked, and the experimental section was set up. As to the place for test, conducted were collection of information on adaptive plant species, bacterium species, meteorology and precipitation pattern, soil analysis, etc. Concerning the bacteria, bacteria were newly separated and tested at the survey site, besides the species to be tested. After planting, measurement of the growth amount of plants, etc. were conducted grasping the meteorology and the water-pouring state during cultivation. For the basement, three kinds of spoils were used, and permeability is different in each spoil. Permeability is an important factor to plants. Too good permeability and too bad permeability are both not good. A future follow-up survey will make what kind of spoil is suitable for eucalypti possible. (NEDO)

Cuttings from a test drilling in the Kuenohira district, Oita Prefecture, are subjected to analysis. The result of ground surface investigation suggested the presence of a magma reservoir to serve as heat source and a highly permeable zone along a fault to help the formation of a thermal water retention system. At the N9-KH-1 drilling site, however, no geothermal reservoir is found along the periphery of the subsidence in the western part of the research area. In this district, it is deemed, no geothermal reservoir has been formed due to shortage of heat supply from the heat source and insufficient geothermal water activity. It is also deemed that the district, in which fractures of the E-W system, NNW-SSE system, and NE-SW system are distributed, is a region at which meteoric water flows into larger convection systems. As for the westward stretch of the geothermal reservoir (where the N9-KH-1 site is situated) that has developed on the swell of the basement, detected to exist at N2-MW-2 and N3-MW-6 in the eastern part of the research area, it is found to be not so extensive.

For the purpose of promoting photovoltaic power generation, analysis and evaluation were conducted on the data of the project of the field test in public facilities for example. This paper describes the fiscal 2000 results. The equivalent array operation time was 2.98 h/day and, by multiplying it by the output of the standard test condition, a generated output was obtained. The system generating efficiency was 0.102 while the inverter energy efficiency was 0.917 on the average. The average array performance ratio was 0.778 and the system performance ratio was 0.714. The analysis on cost effectiveness of the installed systems has an important bearing upon the future introduction, promotion and development. The power generating cost (the annual cost was calculated as the sum of the capital cost, the direct cost, and the administrative expenses) decreased as the installation year progressed, with the average at the sites installed in fiscal 1997 at 93 yen/kWh. The system cost (calculated by dividing the construction cost by the array capacity) also decreased as the installation year became more recent. The annual maintenance cost showed a wide range from 500 yen to 30,000 yen/kW. Answers from the sites that the systems were running smoothly were 38 to 45%, while those that trouble occurrence was frequent were 2.4% on the generating systems and 12.9% on the measuring systems.

This paper summarizes the result of a survey for promotion of geothermal development and an overall analysis of the Akinomiya area in fiscal 1996. The subject area is located in Katsuo Town in south of Akita Prefecture. The geothermal reservoirs are regulated by the irregular construction created by upheaval and subsidence of the pre-Tertiary basement rocks. The underground temperature construction shows the temperatures rising toward Mt. Yamabushi. The latest geothermal activities should have taken place after the eruption of Mt. Takamatsu. The geothermal activities near the Arayu area have been most active until recently, and is still predominant. Transformation activities were active in the former period of the Pleistocene era. The acidic transformation band has been active after sedimentation of andesites in Mt. Takamatsu thereafter, which should have been active not only in areas where it is now active on the ground surface, but also in greatly wider areas. Geothermal fluid flows being regulated by faults, whereas fractures with high permeability existing along the faults are suitable for developing steam collection. Hot spring waters were produced by the geothermal fluid having risen along the faults and been mixed with and diluted by ground surface water near the ground surface. Areas promising for geothermal development would spread over the areas with high permeability along structural lines such as faults which show the convection type temperature pattern and temperatures higher than 250 degrees C.

A survey was made on coal supply potentiality in Bowen Basin in Australia. The main coal beds exist in the order of four beds in the Permian period. The oldest bed is the Reids Dome bed in the Lower Permian period, deposited in the south-west part of the basin. The later wide-area transgression has caused the Back Creek bed groups to deposit, whereas three coal measures have deposited in a concave on the raised basic bed. Later, the ocean has invaded into the entire basin. After having turned into the Upper Permian period, regression had occurred from north to south, where major coal measures such as the Moranbah and German Creek beds had deposited over the entire basin. Further regression has taken place to south, causing three uppermost coal measures to have deposited over the entire basin. In major part of the areas identified currently with existence of coal measures, and even in areas without mines, the mining right or the exploration right has been established, limiting the areas having development potentiality. Five abandoned mining areas exist in the Rangal coal measure, two in the Moranbah coal measure, two in the Reids Dome coal measure, and one in the Baralaba coal measure. There is a possibility of discovering areas developable for a scale of several ten million tons. (NEDO)

Described herein are the FY 1991 results of the R and D project aimed at establishment of superprecision machining technologies for developing machining technologies and nano-technologies aided by excited beams. For increasing the excimer laser output, the discharge-exciting technologies necessary for designing the 2kW laser as the final target are established. The service life tests are started to demonstrate the member service life of 10{sup 9} shots or more. For development of the technologies for large-current composite ion beams, the plant is constructed to attain the final targets (100keV, 2A, width: 500mm or more). The currents reaching the substrate are developed to have 2.8mA with the Ar ion and 2.9mA with the Ca ion by, e.g., developing the ion sources and improving functions of the ion beam controlling systems. Researches on the surface modification technologies for producing the superhigh-quality metallic surfaces involve composite ion implantation and providing the modified layer of Ti-B-based hard compound. Corrosion rate of the modified titanium surface in a boiling sulfuric acid solution is reduced from 300mm/year to around 0.13mm/year. (NEDO)

The research involves tests and studies conducted for the evaluation of corrosion resistance of various metallic materials in molten iodine and for the selection of materials to stay usable under iodine-handling conditions. In fiscal 1982, an iodine transportation system is studied, and corrosion tests are conducted for panels of carbon steels, various stainless steels, titanium, niobium, tantalum, etc., of the grade available in the market, under the conditions where the temperature is 113-170 degrees C, I{sub 2} contains 0-10wt% H{sub 2}O, and the gas phase is of N{sub 2}+O{sub 2}. It is made clear as the result that the effect of water present in I{sub 2} is fairly grave while the influence is but a little of the intensity of temperature and the amount of O{sub 2} gas on the corrosion rates of the respective materials, that materials other than niobium and tantalum are not usable as corrosion resistant materials, etc. In a real device, it is recommended that composite materials be used in the form of a liner or the like because both niobium and tantalum are high-cost materials and therefore create economic disadvantages if employed for the construction of pipes, heat exchangers, etc. (NEDO)

This paper describes a development of air cooling equipment for gas turbine combustion in a 1090-MW combined plant and a discussion on its cooling effect. An open-type gas turbine reduces its output when suction temperature rises. This is a characteristic for a combined plant with high heat efficiency not capable of exhibiting its ability in summer. As a result of testing cooling methods, water spraying nozzles utilizing latent evaporation heat of water were installed at a gas turbine suction opening. Effects of cooling the gas turbine combustion air resulted in reducing the gas turbine suction temperature by 1.8[degree]C as a result of water spray at an ambient temperature of 30[degree]C and a relative humidity of 60%, increasing the plant output by 12 MW as a result of cooling the suction air, and improving the heat efficiency by about 0.035%. The amount of ammonia used for reducing nitrogen oxide generation was reduced by 10.8 kg/hr. Under an assumption of experimenting the water spray in summer on a 15-hour per day basis for 50 days, a calculation indicates an annual economic effect of about 13.5 million yen. 8 figs., 8 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.

There is a move in Europe and America to establish their own standards for the polymerase chain reaction (PCR) technique although it is a technique essential to biotechnology, and it is feared that such will restrain Japan's activities. In its effort to counter the move, Japan is exerting its own endeavors, hoping that it will profit from international standardization of criteria for the PCR technique. The Japanese effort aims at establishing international standards by unifying measuring procedures in the PCR technique and by enhancing the general-purpose feature of the data involved. In concrete terms, items available on the market, such as test and research equipment, reagents, and electronic instruments for use in measurement, are compared with each other in terms of performance, and basic specifications necessary for standardization and basic data on quality are collected.

The paper reported the results of the long-term jetting test, etc. which were carried out as the forth survey of the geothermal development promotion survey in the Akinomiya area, Ogachi town, Akita prefecture. The jetting induction and the situation of production/reduction were described as follows. N9-AY-3 began to well spontaneously after being induced by sending air up to wellhead pressure of 4.8 MpaG. Damping was recognized for a month or so after the start of jetting. After that, however, no damping was recognized, nor was recognized the deterioration of the fluid enthalpy with age. The pH of geothermal water was definite, approximately 8, and the electric conductivity and Cl concentration were 8,500 {mu}S/cm and 2,600 mg/L, respectively. The maximum jetting capacity of N10-AY-8 was 10.4t/h in steam and 8.9t/h in geothermal water at wellhead pressure of 0.24 MPaG, and after that, it showed a tendency to lower. The flow rate of reduction of N8-AY-1 changed from 80-90t/h at the beginning to 60-70t/h. With the continued reduction, the lowering of reduction capacity was recognized. In the test, the following were carried out: temperature/pressure/spinner logging, test on pressure transition, survey of fluid properties, survey of jetting microseisms, etc. (NEDO)

Technical trends were surveyed concerning the recovery and the use as fuel of low-concentration methane gas or the like contained in the air ventilated out of coal mines. Methane gas recovery technologies include high-temperature incinerators and catalytic incinerators designed to collect heat, method of conversion of methane to CO2 using microbes named methanotrophs, and adsorption methods using activated charcoal, zeolite, or the like. Among technologies that have reached a practical level in the utilization of mine methane gas, there are the temperature regenerative flow-reversal reactor (TFRR) and the catalytic flow-reversal reactor (CFRR) utilizing high-temperature oxidation reaction. TFRR has been reported effective by MEGTEC System after a 6-month operational test of a 3.0m{sup 3}/s plant at a British coal mine. Test and research are over with CFRR, which is now ready for a commercial scale verification test. Recovery by adsorption, though worth further research efforts, is economically away from commercialization at the present stage, and wants more studies of adsorbents, etc. (NEDO)

There is a move in Europe and America to establish their own standards for the polymerase chain reaction (PCR) technique although it is a technique essential to biotechnology, and it is feared that such will restrain Japan's activities. In its effort to counter the move, Japan is exerting its own endeavors, hoping that it will profit from international standardization of criteria for the PCR technique. The Japanese effort aims at establishing international standards by unifying measuring procedures in the PCR technique and by enhancing the general-purpose feature of the data involved. In concrete terms, items available on the market, such as test and research equipment, reagents, and electronic instruments for use in measurement, are compared with each other in terms of performance, and basic specifications necessary for standardization and basic data on quality are collected. The effort involves, in more concrete terms, the measurement of thermal cycler temperature distribution, the evaluation of heat-resistant DNA (deoxyribonucleic acid) polymerase temperature sensitivity and accuracy, and the evaluation of performance of CCD (charge coupled device) camera systems and Polaroid camera systems to be used for the evaluation of PCR products.

This paper describes research on materials of equipment for the second stage reaction in relation with development on a hydrogen manufacturing technology by using the iodine system cycle in the thermo-chemical method. The second stage reaction produces MgO, I{sub 2} and O{sub 2} by decomposition of Mg(IO{sub 3}){sub 2} at 600 to 650 degrees C. Corrosion tests were carried out by using 25Cr-20Ni steel and Ni-50Cr alloy having shown relatively high corrosion resistance in the researches to date, which were added with trace amount of different alloy elements. The tests were performed in gas mixture of I{sub 2}, O{sub 2} and H{sub 2}O at 600 to 700 degrees C for 48 to 192 hours. The average corrosion rate of 25Cr-20Ni steel was reduced by adding Y(0.2%), Ca (0.2%) or Si+Al (1%Si+1%Al), by which relatively uniform corrosion pattern was shown, and the corrosion resistance was improved remarkably. The average corrosion rate of 25Cr-20Ni steel showed a trend of increasing by adding Si and Nb, and non-uniform corrosion like pitting has occurred, revealing that it is not preferable from the aspect of corrosion resistance. The average corrosion rates of the tested materials tended to become somewhat greater under heat insulated condition than under continuously heating condition. Effect of Mg(IO{sub 3}){sub 2} deposition is very small. (NEDO)

The compound semiconductor production process is tested under a microgravity by the space experiment/observation free flier (SFU), to reduce the photovoltaic power generation cost. Described herein are the FY 1996 results. The device is confirmed to work as planned by the full-scale test conducted in FY 1995, when it stood on the orbit and was recovered by the space shuttle STS-72 January, 1996. The recovered SFU-carried devices, including the electrical furnace and related subsystems, were found to normally function, and it was concluded that they could be evaluated and analyzed after the flight. The comprehensive evaluation and analysis of their electrical, mechanical, thermal functions have confirmed that they functioned and showed performance as planned, demonstrating validity of the designs and production procedures. The test samples were taken out of the recovered combined furnace, focus furnace and single-heat furnace for the space environment utilization tests. The other samples had much more uniform compositional distributions than those produced on the ground. (NEDO)

This project studies the testing/evaluation methods for spreading fuel cells for automobiles. Described herein are the FY 2000 results. The problems involved in evaluation of the single cell units are classified into those involved in the cell construction and methods of evaluating the operation performances of the single cell units. These problems are analyzed mainly by literature survey. The mode simulation tests will be greatly simplified, if the system can be tested on the bench without being actually boarded on the vehicle. Therefore, this project is aimed at development of a comprehensive mode simulator which can be automatically operated corresponding to the running modes of various countries, to test the performance of FCEV and to examine the effects of each component independently on the vehicle performance. The factors required to reproduce the actual driving states of an FCEV on the bench are analyzed, and the conceptual designs are drawn for the controlling algorithms. It is necessary to standardize the stack and reformer testing methods, in order to evaluate the fuel cell system components. For these objects, the prototype units are constructed to evaluate 10kW direct hydrogen type stacks and 5kW methanol reformers. The units are also constructed to evaluate the high-pressure (1MPa) reformer reactors and hydrogen separation membrane systems. (NEDO)

In high-technology industries such as the semiconductor industry, cleaning operations are indispensable. In these industries, replacement of the current method with a new one has become an urgent matter, thanks to the new control imposed on pollutant CFC (chlorofluorocarbon). Using a supercritical fluid, whose density and other features may be regulated extensively and continuously by controlling temperature and pressure, various conditions may be set in detail for the cleaning element, such as the dissolving power, dispersion force, surface activity, and chemical reactivity. The fluid is environmentally friendly and free of pollution. Facilities for recovering, regenerating, and circulating the solvent are incorporated into a test cleaner built in the preceding fiscal year, and a new system is completed. The system is operated in a test run for performance assessment, and data are collected to specify cleaning conditions best for each kind of the target items. Studies are made to expand the scope of system application for use under supercritical conditions. An experiment is conducted using a pollutant model, and a method to analyze the degree of cleaning is studied using an effective diffusion coefficient. A self-cleaning method is studied for the filter for the regeneration of the supercritical cleaning solvent. A market research is carried out for the commercialization of the industrial cleaning system. (NEDO)

Three technical and business proposals for comprehensive analysis of the survey data for nationwide geothermal resources in Japan were submitted from three U.S. candidate contractor groups, whose evaluations were reported by the Republic Geothermal, Inc. The group comprising of the Aero Service and Golder Associates has few geological engineers, and their engineers related to physical exploration has no experience whatsoever in the geothermal field. The group comprising of the EG and G Corporation, Geometrics, Utah University Research Institute, Mars, and Republic Geothermal, Inc. requires a maximum amount of time and travel expense to adjust the implementations done by four companies. However, this is a group having the largest pan-world geothermal experience, and much experience about Kyushu area of Japan. The group comprising of QEB, Inc., Eureka, and GSC, Inc. requires considerable amount of time and travel expense because of the implementation performed by three companies. The group has some geothermal experience in America, but none whatsoever in Japan. Holding or not holding persons with geothermal experience is an important criterion in selecting the contractors.

As a part of the FY 1997 survey of the promotion of geothermal development, the gravity filter analysis was made of the data processing in the Tsujino-dake area of Kagoshima prefecture, and the results were summarized. The geothermal fluid used in the Yamagawa geothermal power plant has the residual magma brought by activities of volcanic rocks of the Ata central shield volcano as heat source, and the fracture system and deep intrusive rocks are reservoirs. A small scale of gravity anomaly area is located, and it reflects high-density volcanic rock masses which are distributed on the earth surface or shallowly under the ground. The ridge stretching from Kiyomi-dake to the Narukawa tunnel and the ridge connecting Kuze-dake and Tsujino-dake are in the high-gravity area and reflect high-density rocks in the shallow part and deep part. There is a possibility of the existence of the fracture system in the high-density deep basement. Calderas continue close to the south of the high-gravity ridge stretching from the Kiyomi-dake to the Narukawa tunnel, and the fracture system which brings the eruption of volcanic rocks of the Ata central shield volcano and the fracture system forming caldera exist in parallel. From the aspect of the geothermal structure, a consideration was made of rock layers which possibly compose the rise of high-density basement in the deep part near the Tsujino-dake. (NEDO)

The electrical stimulation of the auditory nerve can elicit auditory sensations in the subjects with sensorineural deafness. Each stimulating electrode of an electrode array of the multi-channel cochlear implants may stimulate a distinct neural population. However, a great deal of current spreads from each electrode throughout a lymph because of the high electrical conductivity of the lymph liquid. This phenomenon causes the transmitted information to be reduce due to channel interactions. Even if the number of electrodes is increased, the transmitted information will be limited because of current spread. We have proposed the Tripolar Electrode Stimulation Method (TESM) which may succeed in narrowing the stimulation region and continuously moving the stimulation site for the cochlear implants. We evaluate whether or not TESM works according to a theory which is based on the numerical analysis using the auditory nerve fiber model consisted of unmyelinated and myelinated segments. In this simulation, the neural site and the am of the excited fibers are compared with the compound action potentials which we obtained through animal experiments. As a result, based on the numerical analysis using this model, it is also proved that the anodal/cathodal threshold stimulation current ratio increases by decreasing unmyelinated segment between the inner hair cell and the habenula perforate. Also by comparing the result of the numerical analysis with that of the animal experiment, It is suggested that an effect of the unmyelinated segment is not significant. Based on their results mentioned above, we succeed in narrowing a Stimulation region by controlling the am of the currents emitted from the electrodes on both sides. Also we succeed in continuously moving a stimulation site by changing the ratio of the currents emitted from the electrodes on both sides. 11 refs., 14 figs., 1 tab.

In a discharge excitation rare gas halide excima laser, uniform generation and stable maintenance of the excited discharge determines the laser characteristics. In this report, an approximate solution was obtained on the Boltzmann equation (frequently used for the theoretical analysis of this laser) to examine the nature of the solution. By optimizing the conversion of the variables, calculation of an electron swarm parameter in the hitherto uncertain range of the low conversion electric field was made possible, giving a generation mechanism of the uncertainty of the excited dischareg. The results are summarized as below. (1) The Boltzmann equation gives a linear solution for a logarithmic value of an electron energy in the range of low conversion electric field. (2) Time-wise responce ability between the measured voltage, current characteristics of the excitation discharge was clarified and the attachment and ionization coefficients calculated by Boltzmann equation. (3) Dependency of the attachment coefficient on the partial pressure of fluorine and kripton was examined, and the attachment coefficient was found to increase with the increase of the partial pressure for the both cases. 20 refs., 9 figs., 2 tabs.

A total of 49 budding yeast transcription factor disruptants and one conditional transcription over expression strain are produced, to elucidate the gene regulation networks using the gene expression profile data, and to measure the systematic and high-quality gene expression profiles using the Affymetrix's GeneChip system. The program is also developed for accurately predicting the base sequences which regulate expression of given gene groups, based on the uniqueness of the upstream sequences. The analysis with the aid of the program predicts 8 gene expression regulation sequences, which are considered to be novel, from the gene groups of retarded expression by the transcription factor disruptants. The time course gene expression data are produced from the transcription factor SW14 conditional over expression strain. The analysis of the data indicates that the analysis of the subtracted genes using the gene expression profiles from the wild type strain is useful for clarifying the effects of the derived transcription factor over expression.

For widening the application of photovoltaic power generation, the AC (alternating current) module technology was examined for validity, and effective ways to utilize the technology and tasks to solve for its further development were studied. In fiscal 1999, concerning the validity of the AC module technology, it was shown quantitatively that attention should be paid to the inhibition of radio interference although the AC module was the more advantageous when under the influence of shadow. In the study of various measures for utilizing the technology, it was shown that, although the technology contained many tasks to discharge, such as need for downsizing and cost reduction, improvement on environmental resistance, and the prevention of radio interference, yet it had many advantages expected to turn up in the future, such as reduced influence of shadow, high flexibility in system design, and decreased installation cost. In the study of technical tasks to discharge in the course of development, it was stated that AC module integrated inverters (MICs) were already on the market, that an autonomous distributed type system control method suited the purpose of AC module systems, and that it was important to develop a thin MIC technology for application in the next generation.

This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a semiconductor equipment field, viewing until 5-10 years after. For the future semiconductor industry, the favorable cycling of creation of new demands through performance improvement, and further technology innovation through market expansion is essential absolutely. Since technology development is followed by investment, not only the performance of each equipment but also the higher productivity and cost balance of the whole factory are essential. Self-intelligent function and networking are thus necessary for the equipment. As measures for environment preservation and energy saving, such innovative technologies are required as recycling, reuse, reaction process improvement and alternative technology. Because of diverse final products and a short life time of products, a large-scale collective investment is becoming difficult. A mini-line sequential investment production system according to demand scales is under investigation. Some issues such as micro-technology, realization of 300mm wafer, modularization, CIM, reliability and standardization are also described. (NEDO)

This paper describes the achievement in fiscal 1997 of analyzing practical application of a technology to manufacture solar cell silicon raw materials. Silicon consumption for solar cells in fiscal 1997 has increased to 2000-ton level, and the supply has been very tight. For drastic improvement in the demand and supply situation, development of SOG-Si manufacturing technology and its early practical application are desired. The development of the NEDO mass-production technology using melting and refining has completed constructing the process facilities in fiscal 1998, and will enter the stage of operational research. However, insufficiency in the basic data about behavior of impurities is inhibiting the development. In the substrate manufacturing technology, discussions have shown progress on use of diversifying silicons outside the standard by using the electromagnetic casting process. For slicing and processing the substrates, development of a high-performance slicing equipment and automatic rough rinsing machine is under way. Properties required on silicon raw materials vary considerably widely because of difference in cell making systems and conditions, which is attributable to unknown impurity behavior. When 1GW production is assumed, the cell module manufacturing cost is calculated as 137 yen/W, for which low-cost mass production for its realization, slicing productivity enhancement, and cost reduction are required. The paper also describes site surveys in overseas countries. (NEDO)

Fermentation characteristics are investigated for the conversion of glycolate, acetate, formate, and malonate obtained by the oxidation of low-rank coals to poly ({beta}-hydrox butyrate) (PHB) using A. eutrophus cells. Based on the cultivation experiments using one of the organic acids as a sole carbon source, it is found that acetate is the most effectively converted to PHB. When mixed organic acids are used, formate is preferentially consumed, followed by acetate, and finally glycolate. Although malate can not be utilized, it is implied that it might change the pathway flux distributions based on the metabolic flux analysis. Namely, it shows competitive inhibition to succinate dehydrogenase so that its addition during fermentation results in flux reduction from succinate to maleic acid as well as glyoxylate flux and gluconeogenesis flux. It is also found that NADPH generated from isocitrate is preferentially utilized for the reaction from {alpha}-ketoglutarate to glutamate when NH{sub 3} concentration is high, while it is eventually used for the PHB production from acetoacetyl CoA as NH{sub 3} concentration decreases.

Devices that decompose halogen compounds by use of AlPO{sub 4} are built, and studies are made concerning the collection of basic knowledge and findings, the settlement of problems that accompany scaleup, and the elucidation of mechanism of catalytic function occurrence. Tests are conducted at an intermediate plant, when catalytic performance is observed using a unit accommodating 1 liter of catalyst and chlorofluorocarbon (CFC) 12 is subjected to decomposition for the selection of proper operating conditions. Results similar to those from micro-reactor operation are attained when the reaction tube temperature is controlled. On the basis of the results, a real reactor and reaction system are designed and constructed, and CFC12 containing some CFC115 and CFC22 is made to undergo a decomposition reaction in this real reactor. It is then clarified that CFC catalytic decomposition proceeds at a low cost without generating dioxins and that therefore the process is commercially viable. In the study of catalytic adjustment, it is found that adjustment may be sufficiently effected when baking is conducted at 1,000 degrees C even when the extrusion process which demands low manufacturing cost is employed. Studies are also conducted about the mechanism of co-catalytic function occurrence. (NEDO)

In the manufacturing process of semiconductors and in the high tech industry, cleaning is indispensable. At present, when regulation of the use of CFC which used to be much used has been decided on, the conversion to the use of substitutes for CFC cleaning is urgently needed. Transfer to cleaning by water/alcohol/hydrocarbon has been proceeded with, but there are a lot of problems. Out of the development of the cleaning method using supercritical fluid, the paper described the fiscal 1997 result. As to enhancement of efficiency and decrease in size of equipment, a cleaning experiment by high pressure CO2 around the critical point was conducted by integrating nozzle, ultrasonic generator and cavitation generator and adding solvent circulating system. Multi-purpose and energy saving of the equipment were also studied. To establish an analysis method for the cleaning degree, the contaminated component film of trace organic matter with a specified thickness was formed on the silicon wafer, and using the Fourier transform ultrared spectroscopy, a method to determine the film thickness was studied. For the function evaluation for precision machine parts and determination of optimum cleaning conditions, the cleaning/degreasing process of valves were compared with the conventional method. For the product manufacturing, the paper investigated and prepared the data in Japan and from abroad. 55 refs., 79 figs., 18 tabs.

Acetic acid, ant acid, malonic acid got in liquid-phase oxidation of lignite are raw material of biodegradable plastic using hydrogen bacteria Alcaligenes eutrophus was carried out. It was proven that acetic acid was the most efficiently converted into the PHB as a result of cultivating these organic acid as a single carbon source. And, it was utilized to the bacterial cell at the order of ant acid, acetic acid, glycolic acid, when it was cultivated in mixing organic acid, and it was proven to convert into the PHB. Though the malonic acid was not utilized for the bacterial cell breeding, it was indicated that as the result which analyzed metabolism flow distribution by calculating using the culture data, the succinate dehydrogenase of the tricarboxylic acid (TCA) circuit received competitive inhibition, when this is added in culture middle point, and that the flux of griot lysyl acid route and gluconeogenesis route lowers. And, it was proven that it was utilized in the route which comes to the PHB synthesis from acetoacetyl CoA with the lowering of the ammonia concentration on NADPH produced from the isocitric acid, though it was prior consumed to the glutamic acid of tricarboxylic acid cycle in the route, if ammonia concentration is high.

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

Weatherability tests have been performed on devices used in the residential photovoltaic power generation system by means of exposure, with the objectives to analyze and evaluate the safety and reliability due to aging of the devices used in the residential photovoltaic power generation system. This paper summarizes the achievements in fiscal 1995. In the outdoor exposure test on solar cell modules, multi-crystalline silicon solar cell modules were selected as the test specimens, and thermo-couples were embedded in the modules to measure the temperatures. Also for the purpose of comparison, storage test specimens were stored in a constant temperature and humidity chamber. The exposure tests were carried out in three locations of the city of Choshi in Chiba Prefecture, the Miyako Island test site in Okinawa Prefecture, and the Miyako Island seashore. In the measurement and evaluation, appearance observation and measurements of output characteristics and insulation resistance were executed in summer and winter. No noticeable changes were observed in the measurements after lapse of four months and six months. In the outdoor exposure tests of metal test pieces, aluminum alloys were tested for corrosion caused by contact with different kinds of metals. Although the test period was short in the current fiscal year, difference in corrosion degrees in the aluminum alloys was found already in three months. (NEDO)

Weatherability tests have been performed on devices used in the residential photovoltaic power generation system by means of exposure, with the objectives to analyze and evaluate the safety and reliability due to aging of the devices used in the residential photovoltaic power generation system. This paper summarizes the achievements in fiscal 1996. In the outdoor exposure tests on solar cell modules, results of the tests were derived for up to 18 months after the start of the exposure at Choshi City, Miyako Island and the Miyako Island seashore. In the appearance observation, some white rust has appeared in the contact section of the aluminum frames of the solar cell modules and fixing screws, which have been exposed at Miyako Island and the Miyako Island seashore, but no changes that may give influence on the performance of the solar cells have been observed. The results showed performance similar to or slightly inferior to that before the exposure as a whole. The insulation resistances were all found good. According to the result of the outdoor exposure test of metal test pieces, noticeable difference in the corrosion degrees was recognized in the contact corrosion section of the aluminum alloys exposed in three areas having different meteorological and environmental factors. Electroplated zinc was found to have severer pitting corrosion in the contact sections than treatment-free zinc. (NEDO)

With the objectives to analyze and evaluate the safety and reliability due to aging of the devices used in the residential photovoltaic power generation system, weatherability tests have been performed on devices used in the residential photovoltaic power generation system by means of exposure. This paper summarizes the achievements in fiscal 1997. In the outdoor exposure tests on multi-crystalline silicon solar cell modules at Choshi City, Miyako Island and the Miyako Island seashore, the output characteristics after the exposure tests showed a result that the insolation intensity and the change in the short circuit current are approximately proportional, and the temperature in the module and the change in the open voltage are inversely proportional. The module characteristics retention rate showed no change in the 29-month exposure at all of the three exposure locations. The insulation resistance in the exposure test specimens have been good at 2,000 M{omega} or more in all the locations until 18 months have elapsed. However, the test specimens in Miyako Island and the Miyako Island seashore showed 99 M{omega} after 23 months, and 129 to 1,774 M{omega} after 29 months. According to the outdoor exposure tests of metal test pieces, noticeable difference was found in corrosion due to difference in the environment by each exposure location, whose order of the corrosion degree was the Miyako Island seashore > Miyako Island > Choshi City.
