Patent number: 6848424Abstract: A common rail of an accumulation type fuel injection system has a common rail main body, distributing portions and accessory portions. The common rail main body provides an accumulation chamber for accumulating high-pressure fuel discharged from a high-pressure supply pump. The distributing portion can be connected with a pressure introduction pipe for introducing the accumulated high-pressure fuel to an injector mounted to a cylinder. The accessory portion is disposed on a fuel outlet side of the distributing portion and is connected with the distributing portion and the high-pressure pipe in thread connection. The accessory portion has a sealing member between the accessory portion and a connection object on the distributing portion side. The sealing member has a sealing surface formed substantially in the shape of a spherical surface on the connection object side.Type: GrantFiled: November 14, 2003Date of Patent: February 1, 2005Assignee: Denso CorporationInventor: Toshikazu Watanabe

Patent number: 6296035Abstract: Apparatus is disclosed for removing a coating from synthetic resin products, such as an automobile bumper, to obtain improved coating removal rate and improved productivity. A resin material having a coating applied thereto is rolled between a resin-side roll and a coating-side roll which rotate at different peripheral speeds. A shear stress is applied to the interface between the resin material and the coating, thereby removing the coating from the resin material. Pressing means press the coating-side roll towards the resin-side roll with a predetermined force. The resin-side roll and the coating-side roll apply a normally fixed shear stress between the resin material and the coating, ensuring stable coating removal and improved productivity.Type: GrantFiled: March 27, 2000Date of Patent: October 2, 2001Assignee: Fuji Jukogyo Kabushiki KaishaInventors: Hiroshi Yamamoto, Toshikazu Watanabe
