    <p>CAE came to be used as the main developing tool in the manufacturing industry in Japan. Thereby the process in this way was changed greatly by CAE. As the background, Designer's CAE has generally carried out since CAE software has been usually provided with the integrated CAD. However, the precise analytical methods constructed by CAE specialists must be simplified because designers use an ordinary PC which has not enough performance for CAE, and they do not have special techniques to conduct the precise analytical methods. On the other hand, as a social problem, it has been issued how to effectively use the massive disposal of Japanese larch thinnings. The authors have been researched the feasibility of construction timbers manufactured by compressing Japanese larch thinnings. The purpose of this study is to develop a simplified analytical method without using non-linear ones for evaluation of the vibration characteristics of a whole wooden house. The simulation results obtained by the simplified analytical method are in good agreement with the experimental results at low order modes. In addition, it was found that the bending Young's modulus of a compressed wood that was manufactured from the Japanese larch thinning becomes high in proportional to the compression ratio. The reason is that fiber density increase high according to a compression ratio. Moreover, it became clear that the appropriate arrangement of compressed wood can improve the stiffness of the experimental wooden house from the simulation results.</p>

    <p>In next-generation power modules, the mounting of the power semiconductor chip using GaN and SiC, which can work in high-temperature environments over 200°C, is demanded. For the mounting, the lead-free solder with a melting point of around 200°C and high melting point solders containing harmful lead cannot be used. So in late years, the sinter bonding using Cu<sub>3</sub>Sn, which is a Cu/Sn intermetallic compound, attracts attention. For the practical use of the bonding, it is necessary to clarify the strength reliability of the Cu<sub>3</sub>Sn. Therefore, in this study, to evaluate the deformation properties of the Cu<sub>3</sub>Sn, a micro-indentation tests are carried out at temperature from room temperature to 200°C for a bulk sample of Cu<sub>3</sub>Sn made using the arc melting method. According to these results, Young's modulus and tensile strength of Cu<sub>3</sub>Sn in each temperature are estimated. And it is found that the amount of inelastic deformation increases with a rise in temperature.</p>
