It has been successfully examined that the Quantum catalyst is synthesized by newly proposing synthesis system to achieve more than five times photo catalyst reaction velocity that of the most effective existing 7nmФ titanium oxide photo catalyst in ultraviolet radiation environment. This key equipment, Nano-Sonic, is simultaneously facilitated both with supercritical fluid and such comparatively large size bead mill as mild dispersion. 2011-09-04T15:00:00Z http://hdl.handle.net/11133/1737 タイトル: 形状記憶合金テープにより駆動する回転アクチュエータ 著者: 武田, 亘平; 戸伏, 壽昭; 宮本, 浩司 抄録: In order to develop novel shape memory actuators, the torsional deformation of a shape memory alloy (SMA) tape and the actuator models driven by the tape were investigated. The results obtained can be summarized as follows. In the SMA tape subjected to torsion, the martensitic transformation appears along the edge of the tape due to elongation of the edge of the tape and grows to the central part. The fatigue life in both the pulsating torsion and alternating torsion is expressed by the unified relationship of the dissipated work in each cycle. Based on the two-way motion of an opening and closing door model and a lifting and lowering basket model driven by two kinds of SMA tape, it is confirmed that the two-way rotary driving actuator with a small and simple mechanism can be developed by using torsion ofthe SMA-tape. 2011-09-04T15:00:00Z http://hdl.handle.net/11133/1733 タイトル: シリコン基板上窒化物半導体の高品質化に関する研究 著者: 澤木, 宣彦; 岩田, 博之; 川北, 将吾; 本田, 善央 抄録: Growth of a high quality GaN on a silicon substrate has been attempted. In order to prevent Ga-Si reaction at high temperatures, an AlInN alloy was tested as the intermediate layer between the GaN grown layer and the Si substrate. It was found that a film as thin as 6nm reduces the threading dislocation density in the GaN top layer. In a carbon doped AlGaN on Si, FTIR spectra showed a new specific signal at 945cm-1 following a strong signal at 888cm-1 due to Al-N bond. The new signal was attributed to the LVM due to Al-C bond. This suggests that the carbon has been doped on the nitrogen site to be an acceptor in the AlGaN. 2011-09-04T15:00:00Z http://hdl.handle.net/11133/1734 タイトル: 企業内研修の有効性向上のためのシステムづくり 著者: 小橋, 勉; 韓, 三澤; 藤川, なつこ 抄録: Many corporations have done corporate education to develop their performance. However, there have been the pros and cons on it. Based on the status quo, we examine the ways and conditions to improve the effectiveness of corporate education. First, we make clear how corporate education is recognition understood today. Second, reviewing the history of it and we theoretically identify necessary conditions to improve it. Third, we use a case study to exemplify the theoretical consideration. We focus on the POSCO, a large steel manufacturing company in South Korea, which has introduced Toyota Production System as a way of corporate education to improve its efficiency. Then we identify three factors which led to higher productivity; formulation of a system as a whole organization, commitment of top managements, and penetration to the people at the actual work in the factory, Lastly, we show theoretical implication in terms of organizational learning research. 2011-09-04T15:00:00Z
