Patent number: 9993997Abstract: The present invention provides a laminate having a high fluorohydrocarbon resistance even when used at a high temperature and suitable for use as a sealing member such as oil sealing, gasket and the like. In a laminate including a metal member, and an adhesive and a hydrogenated nitrile rubber formed article laminated on the metal member, the adhesive is formed from a cured product of a composition containing a resin containing not less than 90 mass % of a novolac type phenol resin having a gelling time, as measured by Japanese Industrial standard (JIS) K 6910:2007 “gelling time C method”, of 50 sec-150 sec at 150° C., and a curing agent.Type: GrantFiled: February 26, 2014Date of Patent: June 12, 2018Assignee: MITSUBISHI CABLE INDUSTRIES, LTD.Inventors: Taishiro Sasaki, Masanori Fujii, Hironori Oida, Nobukazu Fujii

Patent number: 9074688Abstract: In a rotary shaft seal configured such that first and second seal elements (1) and (2) each having a fundamental thickness (T) and each curved through a curved wall portions (5) of a corresponding one of the first and second seal elements (1) and (2) to have a generally J-shaped cross section are arranged so as to be curved in opposite directions along a shaft center (L), a wide circumferential groove (7) is formed in each of opposed surfaces (6) of the respective curved wall portions (5) of the first and second seal elements (1) and (2). Under use conditions (where the seal is inserted), extreme end portions (8) of the first and second seal elements (1) and (2) are in contact with an outer circumferential surface (9a) of a rotary shaft (9) with a peak contact pressure such that a contact width (E) is equal to or less than twice the fundamental thickness (T).Type: GrantFiled: December 24, 2010Date of Patent: July 7, 2015Assignee: Mitsubishi Cable Industries, Ltd.Inventors: Nobukazu Fujii, Hironori Oida

Patent number: 7722052Abstract: A rotation shaft seal to prevent inner leak from increasing along high-pressurization of sealed gas. A staged portion is formed on an outer case, and an end face on an inner side of the staged portion is covered with rubber to form a ring rubber portion of which end face is covered. A rubber end face of the rubber portion and a face on a peripheral edge of a seal element are pressed to each other.Type: GrantFiled: March 20, 2007Date of Patent: May 25, 2010Assignee: Mitsubishi Cable Industries, Ltd.Inventors: Hironori Oida, Tetsuya Ashida

Patent number: 7083171Abstract: A metal seal of ring as a whole disposed between a first contact flat face portion and a second contact flat face portion parallel to each other. This metal seal has a middle base portion, a first contact convex portion, and a second contact convex portion. The first contact convex portion protrudes from an inner side and the second contact convex portion protrudes from an outer side. The metal seal generates torsional elastic deformation around the middle base portion as a center in an attached and compressed state.Type: GrantFiled: July 13, 2005Date of Patent: August 1, 2006Assignee: Mitsubishi Cable Industries, Ltd.Inventors: Hironori Oida, Tetsuya Ashida, Takayoshi Mitsui
