Various magnetic information data from solidification or deposition up to date are contained in rocks. For the analysis of remanent magnetism, in general, the stable thermal remanent magnetization and the secondary magnetization are separately evaluated using vector variations determined by the location changes of magnetic pole from ac demagnetization or thermal demagnetization. Especially, in geothermal fields, the remanent magnetism in rocks is complicated due to the predominant alteration. When the remanent magnetism of rocks can be precisely measured and the primary and secondary magnetization can be evaluated, important data can be obtained, which represent oriented core samples required for evaluating the geothermal reservoirs. A rock remanent magnetism measuring system using superconductive magnetic shield has been developed, to evaluate the location of magnetic pole. This system can distinguish the remanent magnetization in rocks, and can be applied to the remanent magnetism in rocks in which the location of dipole model is shifted from the center of core. Important basic data of orientation information in rocks can be provided. 6 figs.

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

Mitsubishi Rayon shared investment with the Dynatech Company in Canada to produce carbon fiber tanks used in natural gas cars, and attempted to monopolize the supply of carbon fibers for tanks. As for the natural gas automobile with low air pollution and exhaust of carbon oxide compared to gasoline automobile, a heavy CNG tank is the bottleneck of its popularization, and its weight could be reduced to one fourth of a steel tank by using carbon fibers. In Japan, only steel tank has been licensed until now. Selling will be increasing in Japan by the co-operation with the Dynatech Company since this carbon fiber can be used from this April.

In the paradigm that propelled polymer chemistry, there are involved the establishment of polymer concept, engineering plastics, regulation of higher ordered structure, and precision polymerization. The first two produced the polymer chemistry era in the 20th century. The regulation of higher ordered structure and the precision polymerization are the fundamental technologies supporting the polymer chemistry of the 21st century. The precision polymerization is a technology for regulating the stereospecificity, sequential structure, and molecular weight of polymers by regulating atoms and molecules and is referred to the following important techniques to be concrete. In the precision addition polymerization, stereospecific regulation and purification of active site to give living polymers are required while, in the precision condensation polymerization, regulation of condensation probability process to be secondary Marcov chain is necessary, as is the establishment of non-defect condensation condition avoiding high temperature deterioration and the like. In the biomimetic precision polymerization, key issues are the method of incorporating molecular recognition control and sequential structure control by living organs into an industrial process. If the higher ordered structure can be regulated by the precision polymerization, it is possible to obtain numerous high performance/high functional materials such as superconductors. (NEDO)

In order to perform efficient and safe controlled blasting, attaining sufficient detonation from explosive is important. Therefore, a mechanism of detonation in a bore hole was studied. Two detonation phenomenon measuring methods were established: one is a continuous detonation speed measuring method by using a resistance wire probe, and another is a detonation mark observing and evaluating method using aluminum and metallic lead plates. Assuming delay blastings in multiple bore holes used practically, discussions were given on detonation phenomena of explosives under pressurized condition. Under dynamic pressure condition, size of the pressurization and delay time of the detonations affected largely the detonation. Discussions were given on blasting effect and safety according to difference in forward initiation and reverse initiation. The reverse initiation method was verified to have excellent blasting effect, maintain good face conditions, and assure safety against inflammable gases. A precision initiation method was developed, which can control the initiation time of a detonator more precisely. The initiation accuracy is more than 1000 times greater than the ordinary instantaneously detonating electric detonator. The precision control of the initiation time proved to develop greater crack propagation. Vibration and stone scattering were also controlled. This paper also describes application of the method to a rock elastic wave exploration technique. 136 refs., 99 figs., 13 tabs.

In a factory with a multi-stage production system, push-type scheduling methods can hardly improve the production rate without increasing the stocks of intermediates. For products whose specifications are known before their orders, a pull-type scheduling method named Kanban system has been developed, and has succeeded to improve the production rate without increasing the stocks of intermediates. The Kanban system, however, is not applicable to custom-made products whose specifications are not known before their orders. In this paper, a 'Virtual Kanban (VK) system' is presented as a pull-type scheduling method which is applicable to custom-made products, and its usefulness is demonstrated by simulation of an application specific integrated circuit manufacturing facility.

Research and development on precision catalytic polymerization aims at developing polymerizing catalysts that can control arbitrarily the molecular weight and three-dimensional regularity by which rapid enhancement can be expected in performance of additional polymerization type polymers, and the primary structure of terminal groups. Works are being done on two sub-themes of ultimate additional polymerization and orientation catalyst polymerization. The research and development of the ultimate additional polymerization included structural control in polymerization reaction in vinyl chloride, vinylester and acrylic monomers, radical polymerization with precision orientation control, anionic polymerization with precision structural control, and precision polymerization utilizing asymmetric metal porphyrin complexes. In the research and development of the orientation catalyst polymerization, the orientation catalyst polymerization was researched and developed, elementary reaction of metallocene was elucidated, high-performance carrier catalysts were developed, advanced function polymers were synthesized at high precision based on metathesis, and improvement of functions of polyolefin was researched and developed. Surveys and studies were carried out on fundamental technologies common to the above two themes re-commissioned to five universities. (NEDO)

This paper reports discussions on subsurface structure of the Kobe area by means of microgravity survey. A Bouguer anomaly distribution graph was obtained (which is close to a near straight line) by measuring the gravity at measurement points with an interval of about 25 m along a traverse line (with a total length of about 1.7 km) in an approximately NNW-SSE direction crossing the downtown of the city of Kobe. Viewing the residuals to a straight line linking the values at both ends of the traverse line revealed that the gradient in the Bouguer anomaly distribution changes as if it is bent at a point near the center of the traverse line as a boundary. Deriving the residuals from fine changes seen in a distribution graph for the residuals made clear that this residual distribution has two discontinuous points. The paper indicates that the bending point in the former case corresponds to a reverse fault in a base bed of a flat land as compared with the result of model calculation on the base structure and gravity distribution. The discontinuous points in the latter case agree with positions of fault distribution derived by a reflection elastic wave survey. 6 refs., 4 figs.

The needs for low power LSIs have rapidly increased recently. For the low power LSI development, not only new circuit technologies but also new design automation tools supporting the new technologies are indispensable. The purpose of this project is to develop a new design automation software, which is able to design new digital LSIs with much lower power than that of conventional CMOS LSIs. A new design automation software for very low power LSIs has been developed targeting the pass-transistor logic SPL, a dedicated low power circuit technology. The software includes a logic synthesis function for pass-transistor-based macrocells and a macrocell placement function. Several new algorithms have been developed for the software, e.g. BDD construction. Some of them are designed and implemented for parallel processing in order to reduce the processing time. The logic synthesis function was tested on a set of benchmarks and finally applied to a low power CPU design. The designed 8-bit CPU was fully compatible with Zilog Z-80. The power dissipation of the CPU was compared with that of commercial CMOS Z-80. At most 82% of power of CMOS was reduced by the new CPU. On the other hand, parallel processing speed up was measured on the macrocell placement function. 34 folds speed up was realized. (NEDO)

Fourier seismology capable of determining quantities related to elastic wave velocity dispersibility and non-elastic damping is under development, and studies are under way for the development of a sub-surface probing technology utilizing this seismology. It is deemed that the above-said quantities are related to the occurrence of earthquakes, behavior of sub-surface water, and migration of magma. In this method, precisely controlled sinusoidal waves are radiated and the received spectral data is subjected to cepstrum analysis, advantageous over other methods in that it achieves a high S/N ratio in a non-destructive way, facilitates deep structure analysis, and capable of monitoring changes with the elapse of time in such a structure. A newly-developed high-mobility transportable quake generator is described, which covers a wider frequency range and aims at the short-distance exploration of sub-surface conditions. Important components of the quake generator include an eccentric mass bearing capable of dealing with high-speed rotation enabling high frequency oscillation, variable mechanism for the primary moment of inertia, exciter and ground surface coupler allowing operations on a soft ground, and torque cancelling mechanism for the excitation of SH waves only. 3 figs.

Autonomic neuropathy function immediately after a change to upright posture has been evaluated by applying transient response function of the system to the blood regulation system. The impulse response function was determined from the change in heart rate before postural change to the upright posture, and was compared with the transient change immediately after a change to the upright posture. The time series of R-R interval of electrocardiogram was used as the time series of the change in heart rate. To determine the impulse response function, an autoregressive model was applied to the R-R interval time series. The impulse response function at the steady state is a transient reaction at the impulse stimulation added to the blood regulation system. The R-R interval decreases rapidly by the autonomic neuropathy reaction in which the blood is rapidly transferred into the legs immediately after a change to upright posture. There is a close correlation between the initial temporary decrease in R-R interval and the impulse response function derived from the change in heart rate immediately after a change to the upright posture. Accordingly, the blood regulation and autonomic neuropathy functions can be evaluated by the impulse response function without actual standing test and load of tested persons. 9 refs., 3 figs., 1 tab.

The evacuation-support system is under development for not only the aged bedridden persons but also the persons disabled in exercising movement to excrete by themselves. When the person lying on his bed is going to excrete, his sequence of actions to be taken is to sit down on his bed, walk to the toilet, sit on it, simultaneously take off his clothes and excrete. After the excretion, the above actions are reversely taken as for as he lies on his bed. Researches are being made into the mechanical system which partially or entirely supports the above five necessary actions. The system structuring can depend upon the following five types of disabled persons` residual function: difficulty in sitting or moving without help. Paralyzed lower extremities and partially impaired upper extremities. Ability to walk with functional assistance. Ability to stand up with support but walk unstably. Ability to walk, leaning on and along the railing. In the present project, its three constituent elements are being developed which are the multi-functional bed internally equipped with transferring/riding/mounting apparatus, transfer support apparatus and multi-function portable toilet. The development of the present system is expected to be followed by that of the self-supporting excretion system which will be proper for Japanese houses. 3 figs., 1 tab.

The development of new seismic sounding system based on the new concept of ACROSS (Accurately Controlled Routine-Operated Signal System) are aimed. The system includes not only new seismic sources but also the analyzing software specialize for the monitoring of the change in subsurface velocity structure, especially in the area of fluid resources. Powerful sources with good portability are strongly required for the practical data acquisition. Portable ACROSS sources (HIT) are developed. The system is mainly used to obtain the high resolution structure with relatively short penetration distance. The principal specifications are as follows: (1) 100Hz in maximum. (2) Linearly oscillating single force. This is generated by the combined two rotator moving opposite directions. (3) Variable force with little work. (4) Very simple source-ground coupler just put even on the soft ground. The system was operated at Yamagawa geothermal plant for two months. The result of the experiments are: (1) We confirmed the stability of the source over wide frequency range up to 100Hz. (2) We confirmed that amplitude and phase of ACROSS signal can be obtained very precisely. (3) Very small change of signal which arise from subsurface velocity change are detected. This indicates that the system can detect the slight velocity change due to variation of subsurface fluid system. (NEDO)

For the purpose of strengthening the international competitive force in the oil industry of Croatia and reducing greenhouse effect gas by introducing energy conservation technology, study was made of the rehabilitation of oil refineries (Rijeka and Sisak) of Croatia's oil corporation, INDUSTRIJA NAFTE d.d. (INA). Rijeka and Sisak Refineries have the oil processing capacity of 6 million t/y and 4.6 million t/y, respectively, but they were constructed during the 1960s-1970s and are now superannuated. In this project, the following are adopted: heightening of the temperature of raw material supply, surging avoidance control, reutilization of condensate water of vacuum distillation, heightening of MEA concentration, control of excess air ratio in heating furnace, preheating of combustion air in heating furnace, application of small-diameter pump impeller, the optimum control of steam/electric system, heightening of temperature of cleaning water of desalting device, stop of adoption of flare seal gas, etc. The energy conservation effect to be expected from the project is 43,065 toe/y in a total of the two refineries, and the reduction in greenhouse effect gas is 133,000 t-CO2/y. Further, the internal return rate is 53.12%, which is very attractive for INA. (NEDO)

With an objective of promotion of geothermal development in the Otaki area in Nagano Prefecture, precision structural test well drilling and investigation works have been carried out, and the result thereof reported. The investigated area is an inclined land with an area of 70 km{sup 2} at altitudes of 1,000 to 2,000 m in the southern foot of the Mitake volcano having Otaki River as the southern border. The investigation has performed during the period from March 2 to September 30, 1987 the drilling of the N61-OT-5 test well hole (depth of 502.0 m), temperature logging, temperature restoration test, water injection test, and core test. The result of the investigation may be summarized as follows: existence of the stratigraphic succession as predicted by ground surface investigation, and existence of the Mesozoic and Palaeozoic strata of the Mino belt were verified; the Mesozoic and Palaeozoic strata of the Mino belt being the base bed have only small cracks, and very little alteration can be identified; X-ray diffraction of powder from test drilled cores recognized very little minerals altered by hot water; and the temperature logging and temperature restoration test identified no temperature indication that clearly indicates existence of heat sources. As a conclusion, there is no alteration due to hot water down to 500 m below the surface in the vicinity of the investigation well, and the possibility of a geothermal reservoir to exist is extremely low.

In the development of a reverse information system, novel designs are created by utilizing a 3-dimensional data base, a high-efficiency fabrication technology for metal patterns for the press-molding of glass is established incorporating some fabrication diagnosing techniques, and a system is constructed under which fabrication accuracy is evaluated and difference data are fed back. In the development of technologies for metal pattern cutting and surface reforming, a metal pattern fabrication technology for molding glass, low in cost and high in performance, is systematized, which enables short delivery. In the diversification of glass products, Ryukyu patterns are collected and Ryukyu glass products are tentatively manufactured by press-molding, and a good result is achieved. In the field of total system technology, basic technologies for an advanced and integrated common production base are established. A virtual reality assisted designing system is developed, under which the designer feels force on the finger tips when preparing a shape for a 3-dimensional structure. (NEDO)

Described herein are the results of the FY1994 research program for solar/energy-conversion technologies retrofitted to existing buildings. The estimated effects and economic viability of retrofitting technologies show that they bring very high energy-saving effects when applied to heating and hot water supply, which consume a large portion of energy, but relatively low energy-saving effects when applied to cooling, solar walls, glazed balconies and transparent insulators. The study on applicability of these technologies in Japan indicates that the technologies which can recover cost within an average life time are those applied to windows, solar collector systems for hot water supply and heating, and transparent insulators. Although these technologies are low in applicability to cooling viewed from the angle of cost recovery, retrofitted radiation type cooling systems improve not only cooling and energy-saving effects but also comfortableness.

Solar technology and energy conservation technology (through retrofitting) which can be introduced into existing buildings are evaluated for their effect and economic efficiency. Studied are technologies verified to be technically feasible at the current stage, introducible into existing buildings without major modification, low in introduction cost, and high in energy conservation effect. How retrofitting technology should be in Japan is discussed. In Japan where demand for heat is smaller than in Europe or America and building service life is shorter, conditions to meet for efficient cost recovery are quite severe. Suitable measures to enhance cost recovery include use of multiple panels of low-radiation glass and light modulators for windows and use of collecting technologies such as solar systems for hot water supply and air solar collectors. Use of a transparent insulator is also recommended. Japanese houses demand repair and reconstruction very often, which helps cost recovery. Dependence on locality is extensive, and this causes difference in solar system application. Since it is high in temperature and humidity in summer in Japan, there is a great need for environmental comfort, and therefore not only energy conservation but also comfortable air-conditioning is important.

Research and development has been made on a cover soil replacement process utilizing waste papers for final disposal facility and a soil flow-out prevention process. This paper summarizes the achievements in fiscal 2000. In evaluating waste paper fibers and waste paper binder films, the safety level was assumed sufficiently high if the fibers are used for the cover soil replacement process for final disposal facility. However, films may have a possibility of destruction if force is applied by such as heavy machines running on the films, hence it must be avoided. According to the on-site scattering test using unattended mixed slurry spraying machine capable of being remotely controlled, the coverage was found good, and scattering of incineration residues can be prevented completely. With regard to monitoring of hydrogen sulfide gas, a system having a hydrogen sulfide sensor and GPS mounted on a slurry spraying machine capable of remote control operation was completed, and its usefulness was verified. By using a wastes disposal facility simulating device, investigations were performed on effects on seepage water and wastes when the cover soil replacing material utilizing waste papers is used, and on changes in the properties of the cover soil replacing material.

The research and development efforts aim to use more magnesium alloys of high performance aboard passenger cars. In the research and development of magnesium alloys for die-casting, studies are conducted about 14 kinds of alloys with their heat treatment properties improved, all based on an Mg-9%Zn-4.5%Al-0.6%Ca alloy which is expected to be excellent in resistance to heat and corrosion. In the development of forging-oriented high-strength magnesium alloys to be excellent in withstanding a hot working process, tractive characteristics superior to those of a forged 6061 aluminum material are obtained from an annealed ZK31 alloy. In the development of a high-performance heat-resistant magnesium alloy die-casting technology, it is found that an injection speed higher than that used for the existing alloys is necessary to achieve a product quality which is sound. This is true for all heat-resistant alloys except the ZAC series. Furthermore, technologies are developed which involve the forging of high-performance magnesium alloys, high-precision high-speed wet cutting, surface reforming of the environmentally friendly type, laser beam welding, etc. (NEDO)
