Patent number: 8716047Abstract: When a p-layer 4 composed of GaN is maintained at ordinary temperature and TNO is sputtered thereon by an RF magnetron sputtering method, a laminated TNO layer 5 is in an amorphous state. Then, there is included a step of thermally treating the amorphous TNO layer in a reduced-pressure atmosphere where hydrogen gas is substantially absent to thereby crystallize the TNO layer. At the sputtering, an inert gas is passed through together with oxygen gas, and volume % of the oxygen gas contained in the gas passed through is 0.10 to 0.15%. In this regard, oxygen partial pressure is 5×10?3 Pa or lower. The temperature of the thermal treatment is 500° C. for about 1 hour.Type: GrantFiled: August 31, 2009Date of Patent: May 6, 2014Assignees: Toyoda Gosei Co., Ltd., Kanagawa Academy of Science and TechnologyInventors: Koichi Goshonoo, Miki Moriyama, Taro Hitosugi, Tetsuya Hasegawa, Junpei Kasai

Patent number: 8678521Abstract: A brake control system includes at least a pair of brake systems respectively connected to a pair of brake operating members L1, L2, and a control unit 10 for controlling the brake forces of the pair of brake systems interlockingly according to a predetermined distribution ratio by operating one of the pair of brake operating members L1, L2. The control unit 10 executes a decreasing control on the brake forces in such a manner that, when releasing the pair of brake operating members L1, L2, the control unit 10 decreases both of the brake forces together, even in a state where the control unit performs the interlocking control so as to decrease the brake force of one of the brake system as the brake force of the other of the brake system is increased in accordance with the predetermined distribution ratio.Type: GrantFiled: May 8, 2006Date of Patent: March 25, 2014Assignee: Nissin Kogyo Co., Ltd.Inventors: Tetsuya Hasegawa, Tooru Koyama, Genichi Hatakoshi
