In this paper we deal with the interaction problems between twin propellers and twin rudders in a uniform flow, as a first step of the theoretical approach to the propulsive performance of twin screw ship. The propeller is treated as an infinitely bladed propeller which is represented by the bound vortex distribution. The rudder load is expressed by the Glauert's mode function, and the rudder thickness is represented by the center plane source distribution which satisfies the boundary condition on the rudder surface. By using these singularities, we make clear the effects of the relative positions of the rudder to the propeller plane and to the propeller center line, and of the distance of two propellers and rudder thickness on the rudder drag in the problems of the propulsive performance of twin propellers and rudders system.

電子機器の高機能化により使用するLSI製品の規模と数が増加している.その一方でLSIの微細化,高集積化により電磁環境適合性(EMC : Electro Magnetic Compatibility)の問題が顕在化している.電子機器の高機能化によりEMC問題は,機器からLSIの問題へと拡大し,電子機器のEMC性能はLSIのEMC性能に大きく左右されるようになった.EMC性能に関して高い信頼性を確保するためには,LSIのノイズ特性を考慮した電子機器の設計が必要であり,LSIと電子機器の協調設計環境の構築が期待されている.本論文ではこの実現に向けて,LSIと電子機器のEMC問題について調査し,EMC解析に必要なLSIのモデルについて検討した.さらに,このEMC解析モデルを用いて電子機器のプリント基板を解析し,協調設計の必要性を示す.

気体潤滑におよぼす分子平均自由行程λの影響を明らかにするため,減圧ヘリウム内でスライダ軸受の実験を行い,λに起因するスリップ流れを考慮した修正レイノルズ方程式による数値解と比較した.λの影響を大きくするため小形軽加重のスライダを用い最大時のλ=0.266 μmにて最小浮上すきま0.1μmまでの実験を行った.その結果λに起因する浮上すきまの減少率65%,クヌッセン数3まで実験と計算とがよい一致を示すことを確認した.

This paper studies theoretically on basic characteristics of torsional vibration of 1-story linear system with uniaxial eccentricity subjected to translational ground motions. Basic characteristics mainly of the torsional component is made clear by deriving mathematical expressions for participation vectors and acceleration magnification factors. Based on these magnitudes of vectors and factors new indices for the dynamic torsional effect are proposed. Proposed simple indices are effective for torsional vibration not only in the ordinary case of large eccentricity but also in the extraordinary case of small eccentricity. These indices also show good agreement with damages of structures in past earthquakes.

This paper examines the measures taken by the Ministry of Education and local governments to close Korean schools in Kyoto City from 1948 to 1950. It utilizes official documents, mainly those of the Kyoto Prefectural government, in order to examine the actual state of Korean schools at the time as reflected especially in the meanings of memoranda concluded with Korean groups. Previous research focuses on the process over a one year period from the "Hanshin education battle" of April 1948 to the closure of Korean schools in October 1949, during which measures were systematically restrictive, beginning with temporary closure to outright suppression. In the case of Kyoto City, however, one can regard this period as one during which both the Korean groups and the government consistently compromised with one another while attempting to determine the place and position of Korean schools. In Kyoto, as a result of negotiations between Kyoto Prefectural Government and Korean groups, two agreements in May 1948, regarding approval of the establishment Korean schools and of a "special class" within public schools, were attempts to reach a temporary settlement between the two sides. As a result of this "Kyoto Memorandum," Korean schools were recognized as either private Korean schools or a "Special Class of City Elementary Schools," and classes continued as before. The following year, however, the Kyoto Military Government deemed this "special class" of schools to be a violation of education laws, and Kyoto Prefecture, which received direct instructions to this effect, revoked the "Kyoto Memorandum" in April 1949. Moreover, Kyoto city temporarily closed the "special class" of schools, and in September it ordered the compulsory closure of a schoolhouse. In October, all private Korean schools in Kyoto City that had been recognized one year earlier in the "Kyoto Memorandum" were also closed by a national government measure to close all Korean schools nationwide.
