Patent number: 7819081Abstract: In a plasma film forming apparatus, two first electrodes 51 connected to a power source 4 and two grounded second electrodes 52 are arranged in the order of the second electrode 52, the first electrode 51, the first electrode 51 and the second electrode 52. A first flow passage 50a formed between the central first electrodes 51 allows a raw material gas (first gas) for being formed into a film to pass therethrough. A plasma discharge space 50b of a second flow passage formed between the first and second electrodes 51, 52 on the both sides allows an excitable gas (second gas) to pass therethrough, which excitable gas is exited by plasma such that the raw material can be formed into a film, but that the excitable gas itself is merely excited but not formed into a film. Those gases are converged at a crossing part 20c between the first and second flow passages and blown off via a common blowoff passage 25a.Type: GrantFiled: October 7, 2003Date of Patent: October 26, 2010Assignee: Sekisui Chemical Co., Ltd.Inventors: Shinichi Kawasaki, Sumio Nakatake, Hiroya Kitahata, Setsuo Nakajima, Yuji Eguchi, Junichiro Anzai, Yoshinori Nakano

Patent number: 6279552Abstract: An exhaust gas re-circulation valve which allows the accurate control of high temperature and pressure exhaust gas flowing through the engine exhaust gas re-circulation passage of a turbo diesel vehicle or the like. Valve seats 28, 29, valves 31, 32 and a valve shaft are mounted on a valve housing 21 and an adjustable adjusting mechanism 36,51,28b,71 is provided which allows both the first valve 31 and the first valve seat 28 and the second valve 32 and the second valve seat 29 to close in abutment by displacement or deformation. In this way even if there is an irregularity in the process or assembly accuracy of the components of the exhaust gas re-circulation valve, it can be absorbed by the adjustable mechanism 36, 51, 28b, 71. As a result the formation of gaps between the valve and the valve seat as a result of irregularities in the in the process or assembly accuracy of the components of the exhaust gas re-circulation valve can be prevented and valve accuracy can be improved.Type: GrantFiled: October 1, 1999Date of Patent: August 28, 2001Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hidetoshi Okada, Sotsuo Miyoshi, Toshihiko Miyake, Shinichi Kawasaki
