In this study, a new welding method which utilizes conductivity of CFRTP (Carbon Fiber Reinforced Thermo-Plastic) is proposed. Electrical current is applied through the CFRTP single-lap joints in thickness direction. Since resistance of joining surface is the highest in the current path, the joining surface is preferentially heated by Joule heating. In this study, spot welding and surface welding were conducted. By applying constant voltage of 5.0V or 10.3V, the joint-surfaces were heated above melting temperature Tm of the material and were welded. In order to evaluate lap-shear strength (LSS) of welded joints, tensile lap-shear strength tests were conducted. As a result, the tensile lap-shear true stress of spot welding is 31.0MPa and LSS of surface welding is 22.0MPa. These strengths were comparable to those that were welded by traditional resistance welding method. It is also found that LSS is changed with welding pressure of joint parts.

Continuous carbon fiber composites can be printed with 3D printers. Many studies detailing elucidations of the mechanical properties of such 3D printed composites have been published, all of which employed a conventional tensile specimen configuration with surface resin layers. In the present study, 0º, 90º, ±45º, and lay-up direction type specimens were newly designed for 3D printed composites without surface layers. Using the 3D printer, both conventional and newly designed specimens with serpentine folded fiber bundles were fabricated and investigated experimentally. The lay-up direction specimen was fabricated using 800 layers. The specimens without the serpentine folded fiber bundles were experimentally shown to be adequate for tensile tests. The lay-up direction specimen had the lowest strength and stiffness, which seems to be related to its surface roughness.

Safety of automobiles is increasingly demanded. To prevent burst of tires, smart tires are currently under development The embedded sensor enables highly precise measurement of road surface friction, and the precise friction measurements make more efficient anti-blocking-system (ABS). In a previous study, the authors proposed a new wireless strain monitoring method that adopts the tire itself as a sensor, with an oscillator circuit. This method is very simple and useful, but it requires a battery to activate the oscillator circuit. In the present study, the previous method for wireless tire monitoring is improved to produce a passive wireless sensor. The capacitance change of tire causes changes of the tuning frequency. This change of the tuned radio wave enables us to measure the applied strain of the specimen wirelessly, without any power supply from outside. This new passive wireless method is applied to a specimen and the static applied strain is measured.

性的破壊的衝動が暴力的行動として学校教育場面で問題化した小6の男児に対して,授業に参加しながら心のケアと人間関係の学びを支援する実践を通して,その有効性と課題について考察した。臨床心理学的専攻の大学院生によるチームサポートは,支援のオリエンテーションが同じでメンバー間の信頼関係が十分であれば,あたかもひとりのセラピストが対応しているかのように進行できること,メンバーの個性をクライエントは父イメージ,母イメージ,男性イメージ,女性イメージなど必要に応じて投影し,取り入れていき,内的成長に有効であることがわかった。その現象や支援関係の特徴をより多くの事例をかさねて分析し,支援のための連携についても考察していくことが今後の課題として残された。
