Patent number: 9541209Abstract: Provided is an attachment structure of a check valve that is easily attached to piping, and does not need time and effort of manufacturing. A valve casing having a collar part is attached so as to be sandwiched between a pair of flanges joined to each other through an annular seal body in an upstream side in a fluid flow direction. In this valve casing, a valve is biased in a seating direction to a valve seat through a shaft and a biasing means.Type: GrantFiled: October 17, 2014Date of Patent: January 10, 2017Assignee: SANKEI GIKEN CO., LTD.Inventors: Kaneyoshi Hayashi, Shigeyoshi Hayashi

Publication number: 20080100060Abstract: A pipe joint is provided that effectively accommodates a relative positional displacement between pipes, thereby allowing unfailing coupling between the pipes. The pipe joint is provided with a flexible pipe main body in a circular cylindrical shape; a pair of flanges that is provided on both ends the pipe main body, and are coupled to end portions of the first pipe and the second pipe that face each other; and a plurality of string members that couple the flanges. Each string member includes a string main body and a pair of stopping members that are provided on both ends of the string main body with a predetermined distance, and the flanges are formed in an annular shape and include a plurality of flange pieces that are separately formed, an ear portion having a coupling hole for coupling the flange pieces, a coupling bolt that couples the flange pieces, and the application bolt that couples the first pipe and the second pipe.Type: ApplicationFiled: October 29, 2007Publication date: May 1, 2008Applicant: Sankei Giken Co., Ltd.Inventors: Kaneyoshi Hayashi, Shigeyoshi Hayashi

Publication number: 20070096468Abstract: A split flange is provided. The split flange may be capable of being fitted firmly around the pipe having a flexible pipe body and a flared portion formed at an end portion of the pipe body. The split flange is provided with two or more arcuate flange members and two connecting members located at both end portions of the flange members and projecting outward from outer circumferential faces thereof. The flange members may be connected to each other to form an annular structure. An operation for fitting the flange members firmly around the pipe body is carried out easily.Type: ApplicationFiled: August 21, 2006Publication date: May 3, 2007Applicant: SANKEI GIKEN CO. LTD.Inventors: Kaneyoshi Hayashi, Shigeyoshi Hayashi

Patent number: 7128095Abstract: A vibration damping bellows with a high vibration absorbing effect and whose a simple structure. In a vibration damping coupling, for example, the vibration damping bellows is formed by interposing viscoelastic material, material with low elasticity, or combination thereof between an inner member and an outer member, which are made of stainless steel. The stainless steel inner member and/or outer member may be omitted when occasion demands. The material of the stainless steel plate, for example, may be SUS 304 that is austenitic stainless steel. Further, flanges to perform connection with pipes may be provided in both ends of the bellows. The viscoelastic material may comprise elastomer such as silicone rubber and vibration damping alloy.Type: GrantFiled: February 17, 2004Date of Patent: October 31, 2006Assignee: Sankei Giken Co., Ltd.Inventor: Kaneyoshi Hayashi
