In this paper, the development of the oil hydraulic load control system using opposed cylinder is reported. In this load control system, a relief pressure proportional-type valve was adopted as the load pressure was changed by the computer. Moreover, the status changes of the pressure and the position etc. of the oil hydraulic actuator and the examination equipment during load test in this system is measured at the same time, and measured data can be preserved in the file. For developing above mentioned system, an original control and measurement program for this system were produced. The control valve for the examination was built in this developed system, and the load characteristics was measured. As a result, it was able to be verified that this system is to be able to evaluate the load characteristic of the oil hydraulic equipment.

A new grinding wheel has been developed, in which very fine SiC whiskers are normally aligned to the grinding surface. Using this grinding wheel, a smooth surface of hardened die steel could be produced with the roughness of 16 nmRy (1.5 nmRa). However, one problem was observed in the grinding process: the grinding stone exhibits a high tendency to loading, and the grinding efficiency thus decreases. In this study, a method to improve the honing efficiency was suggested. A small amount of very fine abrasive grain to added to honing fluids. The experimental results showed that alumina of #8000 grain size is most suitable and a concentration of 1.0 wt% is sufficient to prevent loading. The honing efficiency is remarkably improved by this method.

We have studied the growth instability of InGaN ternary Nitride alloys. A theoretical analysis for asymmetric broadening of phonon mode in measured Raman spectrum was examined with the aid of spatial correlation model. We suppose that the relaxation of the selection rule of the phonon is caused by the deterioration of the crystal, and the asymmetric broadening of Raman spectra is resulted from that Especially, the asymmetric broadening of the E2 phonon mode is enhanced in the region of immiscibility by increasing the indium molar fraction. On the theoretical analyses, we compared with two kinds of dispersion curves tentatively. We could find the correlation length which corresponds to the decay length of the phonon was on the order of 〜10nm. This value is on the same order of magnitude as the size of the columnar structure suggested by transmission electron microscope analyses.

This study shows measured results of the relaxation effect of greens in facilities such as parks and schools using the POMS (Profile of Mood States) which is a psychological test developed in the U.S. to measure changes of mental conditions and mood states. The study shows that the relaxation effect is higher for youngsters when they exercise, rather when they chat and the relaxation effect is higher for them when they spend their recess in a park than staying at school. Therefore, it has been revealed that it is important to effectively use facilities for exercise and green space to improve the relaxation effect.

In order to accomplish a prevention of traffic accidents, it is insufficient to adopt measures in hardware only, such as improvement of the geometric structure of the road, but it is necessary to adopt measures taking into consideration factors on the driver who uses the road by effectively controlling three factors of driving "recognition," "judgment" and "operation". In this study, noting one of three factors, "recognition" of a driver, we aim to clarify the relationship between the visual factor, which is one of cause elements of an accident, and traffic accidents analyzing the relationship between the watching points of the driver during driving and road conditions using an eye mark recorder.

This study aims to present the results of a field study on exercises such as improvement measures to reduce working hours by decreasing the unit time of practice, by gaining timeliness of question and working location by having each team to carry a simple GPS receiver and a mobile phone, and basic education in surveying moving objects using a GPS receiver. This study also aims to produce a practical guidebook for students, who are dispersed over a wide area of a school, to voluntarily carry out measurement practice, after receiving an explanation by the teacher, and it shows its educational effect.

A stiffening Method of existing cylindrical steel piers is studied by experimental and analytical ways. On the experimental way steel piers are stiffened by rectangular steel plates on it. On the Stiffening structures are set using the plates and local buckling points created forcibly on the pier. The part of the pier which yields local buckling is controlled in base zone of it by this Stiffening structures and the ductility of the piers are improved with small increase the ultimate strength of it. We have been able to improve the ductility of piers by the Stiffening structures..

In this paper, I summarized the transition in problems of the Telegraph Avenue commercial area. I also researched the vitalization plan that responds to these. I investigated fundamental ideas on strategies and policies regarding the scenery of the Avenue and the architectural potential. 1) Vitalization plan of the Telegraph Avenue area was made through the cooperation of residents, merchants, the city of Berkeley and University of California, Berkeley. For increasing the attractiveness of this area, this plan recognizes that architectural design and scenery are defined as important. 2) For increasing residential population, the developers of the plan propose that buildings combining commercial and residential use must be developed in the Telegraph Avenue area. The quota system has also been adopted for encouraging small-size businesses, which contribute to the diversity and identity of this area. 3) In aiming at the creation of a comfortable environment that maintains/reflects the characteristics of historical architecture, the Design Guidelines were developed.

In Meiji-era, Chuta Itoh started the study of Japanese architectural history. He had the important relationship with Kakuzo Okakura. Itoh received the essential ideas of traditional Japanese artistic history from Okakura. He wrote architectural section in "The history of the art of Japan" whose Japanese edition was published in 1901. This book was re-edited in 1908 and there Itoh rewrote architectural section and changed recognition of traditional Japanese architecture history in many points. His changes of recognition show the early forming process of the study of Japanese architectural history. So there are very interesting facts.

In this study, the simple method measuring the air permeability of concrete is proposed. In order to investigate the applicability of this method, the air permeability obtained by this method is compared with the air permeability by pressure method and the result of carbonation test. As a result, it is clear that the air permeability by this method relates with that by pressure method and the depth of carbonation qualitatively.

A simple retrofitting method for Japanese wooden structures is proposed. The method is fixing a sheet of plywood on columns by nails. The nail pitch is 50mm and the nail length is 50mm. The wall length ratio of a single-sided retrofitted wall is 1.1, and that of a double-sided retrofitted wall is 2.0. For the application of this method, one-story wooden structures are retrofitted adequately, and the wall of this method is small for two-story wooden structure.

This report shows repair methods of the shoddy work of a HD connector. The repair method using chemical anchors is able to alternate a HD connector. The repair method using a VP, one of metal connectors, has a hard initial stiffness. In case of the method using a VP, the destructive load makes the base timber cracked. These experiences result in the repair method using chemical anchors to repair the shoddy work of a HD connector.

我々は一定の物質密度の中における3世代ニュートリノ振動を考える。すべての振動チャネルに適用できる遷移確率の厳密解を簡単な形で求める。またこの厳密解で標準表示を用いた場合のCP依存性を全てのチャネルで求める。その結果全てのテャネルで物質中のCP依存性は真空中のものと一致する事がわかる。すなわちCP位相をδとしたときsin δ,cos δなどの係数に物質効果を繰り込む事が出来る。これらの係数の厳密な表式も与えた。またZaglauer-Schwarzerによって計算された有効混合角や有効CP位相からも我々と同じCP依存性が出る事を確認する。最後に物質効果に依存しない簡単な関係式として知られているNaumov-Harrison-Scott恒等式がさらに2つの恒等式に分解できる事を示す。

This paper is written primarily for the English teaching staff at the Toyota National College of Technology (Toyota Kosen) to introduce or refresh information on testing and to consider ideas for the future testing of students. It is hoped that the information can and will be used in areas outside this one location and applied to other similar classes.
