Patent number: 8960221Abstract: An electromagnetic pressure regulating valve includes a valve body and causes a valve body to move by an electromagnetic proportional solenoid to adjust an opening degree of a valve passage, thereby regulating secondary pressure to target pressure. A pressure return chamber is formed in the housing, and a diaphragm seal is provided at the valve body. The diaphragm seal receives the secondary pressure of the pressure return chamber to cause the valve body to move toward a closed position. A bearing member is provided between the valve body and the housing. In a gap between the valve body and the housing, a high-pressure sealing member is provided closer to the valve passage than the bearing member, and a low-pressure sealing member is provided closer to the bearing member than the high-pressure sealing member. A buffer chamber connected to a secondary port is formed between the sealing members.Type: GrantFiled: August 4, 2011Date of Patent: February 24, 2015Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Kaoru Nomichi, Yutaka Suzuki, Makoto Ninomiya, Shoji Murakami

Patent number: 5096559Abstract: A cathode roller mechanism comprises a tapered cathode roller for establishing an electrical connection to a semiconductor lead frame and an elastic, frictional pressure roller. The cathode roller comprises a tapered roller body defining a tapered side surface and an electrically conductive stopper disposed on the roller body and having an inner tapered electrode. The pressure roller is arranged so that the path of a drifted lead frame can be corrected, and the drift of the lead frame can be positively prevented by pressing the lead frame in such a manner that no drift of the lead frame occurs. In addition, an auxiliary electrode is provided on the inside of the tapered electrode, a third tapered surface is provided on the auxiliary electrode, and the width of the pressure roller is set to a length sufficient to press a corner of a molded portion of lead frame having the maximum width so that electrical continuity, i.e.Type: GrantFiled: July 5, 1990Date of Patent: March 17, 1992Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Ikuo Sasaki, Shoji Murakami, Koji Abe, Kenichi Onishi
