This paper deals with an experimental investigation on damping capacity of machine tool structures packed with balls. Actual machine tool structure models are constructed, and the effectiveness of the balls packing for the damping capacity improvement is investigated. As a experiment related to actual machine tool structure, two types of machine tool structure models were constructed and the damping capacity improvement due to application of packed balls was examined. The radial boring machine has a construction that a column is fixed on a base and a moving radial arm is on the column. As another example, a milling machine has a column and a head. In many cases, the machine tool base has T-type construction because the table and the supporting column of cutting tool are connected. These machine tool structures are constructed by connecting two cantilever beams. On these machine tool structures, the damping capacity improvement is important. Two pipes are connected by welding.

A guiding principle of design of broadband 3-dB 5-branch-line couplers for millimeter and sub-millimeter wave bands, their designs and their performances are reported. The couplers are designed by a numerical analytical method by using matrices based on the circuit theory. The couplers have good performances, which maintain an amplitude balance to within 1dB and a phase difference of 89-91 degrees over the frequency range of 84GHz to 116GHz.

A stiffening Method of existing cylindrical steel piers is studied by experimental ways. On the experimental way steel piers are stiffened by rectangular steel ribs on it. The Stiffening structures are set using the ribs and local buckling points are created forcibly 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.

This research was performed to analyze the vision of drivers using the loop section of Nagoya Expressway using the eye-mark recorder that enabled simultaneous recording of the gazing point of an examinee on the videotape of the examinee's visual field. The examinees were two, one was in their 50s and the other was in their 20s. Neither one of them had ever driven on the Nagoya Expressway. Through the analysis of the gazing point, it has been found that they were apt to continuously look at the right hand sidewalls when driving right-hand curves on the first driving. The more they repeated driving on the Circling Expressway, the more they were accustomed with driving, and the gazing point dispersed to the preceding vehicle and the lanes on the road. Through this fact, it has been found that installation of devices to attract the eyes of drivers on the sidewalls would lead to ease of driving.

This research was performed to investigate the actual situation of traffic passing the residential area to avoid traffic congestion of the major roads. The investigation was performed in 6 areas of Toyota City. Items of investigation were the road condition of the area, types of traffic accidents that occurred, the traffic volume that passed the area and the speed of vehicles that passed. Almost all of the traffic accidents in the areas were those between vehicles and were mostly head-on collisions at intersections. It was also found that the driving speed in those areas was between 30km/h and 40km/h, which was comparatively low. It was found that the speed went down specifically in the areas where the visibility was low and many pedestrians were walking.

For this paper, the planning process by paying attention to the University Avenue Strategic Plan was researched. And the fundamental points aiming at an attractive area through strategies and policies were pursued. 1) The residents and merchants played an important roll in devising the strategic plan. Fundamentally, they shared a joint sense of ownership regarding the existing problems of this area, perceived images for the future, and planned the definite policies and strategies. In sum, this plan is based on with the original ideas of the residents. 2) Goals of the strategic plan are to raise the attractiveness as the residential area while maintaining characteristics of this area, and to increase the population by repairing and reconstructing obsolete buildings. 3) Strategic Plan has revisions of zoning regulations, limitations on construction, and so on. In aiming at forming an attractive area in the middle/long term, the design guidelines are also reviewed.

Porous concrete has excellent properties as eco-concrete. However, the mix proportion method of porous concrete is not investigated thoroughly. In this paper, in order to determine the mix proportion method of porous concrete, the rheological consideration and experiment is carried out. The maximum and minimum of yield value of paste is calculated by the rheological theory for each aggregate size and void ratio, as the suitable yield value of paste is necessary to produce the proper porous concrete. In addition, the adequacy of these value was considered experimentally.

Maximum displacement response of SDOF system subjected to finite cycle sin wave is calculated in order to estimate the conceivable maximum displacement response of structures. As results, the maximum velocity responses of linear system based on this proposed method are constant. The period of sin wave that makes the structure most deformed is nearby the natural period of that structure. The maximum displacement response of normal bilinear system is caused by 1.5-cycle sine wave on this proposed method. The maximum displacement response of slip-type restoring force character system is caused by 2-cycle sine wave on this proposed method. The estimated maximum displacement response displacement is less than 1.2 times of the displacement based on this proposed method.

我々は任意の物質密度における三世代のニュートリノ振動での遷移確率のCPの依存性を考える。ν_e→ν_μの遷移確率においてCPの位相δの依存性がP(ν_e→ν_μ)=A_<eμ>cosδ+B_<eμ>sinδ+C_<eμ>となることが一定の物質密度の場合にのみならず、任意の物質密度分布の場合にも成り立つことを示す。またν_μ→ν_T transitionでは、P(ν_μ→ν_T)=A_<μT>cosδ+B_<μT>sinδ+C_<μT>+D_<μT>cos2δ+E_<μT>sin2δと表せることを示す。この遷移確率は任意の物質密度分布で成り立つが、物質密度が対称になるとE_<μT>=0となる。これは前の論文で示したようにCPの位相の依存性は物質密度が一定の時と同じになることを意味する。他のチャネルについても同様に遷移確率が求まりsinδ, cosδの高々2次式になることを示す。また物質密度が対称になると、CPの位相の依存性は物質密度が一定の場合と同じになる。

物質中の3世代ニュートリノ振動について考察する。振動確率P(ν_e→ν_μ)=Acosδ+Bsinδ+Cの係数A,B,Cを任意の物質密度で計算する新しい方法を提案する。ここで、δはCPの破れを表す。我々の方法の利点は、従来行われていた微小パラメータΔm^2_<21>/Δm^2_<31>やsinθ_<13>に関する摂動の1次の計算を行わなくても任意の物質密度でCP対称性の破れに関連するAやBの近似公式を導く出せる点にある。この結果として、物質密度一定の場合にすでに他の著者によって導かれている低エネルギーと高エネルギーの近似公式が両方とも容易に導き出せることを示す。このことは我々の近似公式が広い適応領域を持っていることを意味している。

This paper is written primarily for the English teaching staff at the Toyota National College of Technology (Toyota Kosen) to examine team teaching at several institutions for higher education. The system of team teaching at Toyota National College of Technology and other team teaching systems that are being practiced by Nagoya Women's University, Okazaki Women's Junior College, Nagoya Institute of Technology, Fujita Health University, and Nagoya Communication Arts Junior College will be discussed. Information will also be shared about programs presently being used at Chukyo University and Yokohama City University. It is hoped we can improve by comparing and learning from what others are doing.
