Patent number: 11089294Abstract: An endoscope inspection system includes an endoscope inspection apparatus and a package that packages an endoscope. The endoscope inspection apparatus includes a communication connector and a processor. The processor drives an image pickup device circuit of the endoscope to receive a response signal, determines based on the response signal whether a status of an image pickup device circuit is good or poor, and notifies a result of determination. The package includes a first fixing shape portion that fixes the packaged endoscope connector and a first fitting shape portion fitted with the communication connector such that an endoscope-side communication terminal of the fixed endoscope connector is electrically connected to an inspection apparatus-side communication terminal of the communication connector.Type: GrantFiled: June 22, 2020Date of Patent: August 10, 2021Assignee: OLYMPUS CORPORATIONInventor: Hiroshi Niwa

Patent number: 9512878Abstract: A weld line formed by injection molding of a sealing member is formed at a circumferential position out of deepest portions of axial grooves, which form thinned portions of the sealing member (optimally, in a region of a cylindrical surface between the axial grooves in a circumferential direction). Thus, the sealing member is prevented from being provided with parts having locally markedly low strength, and hence damage to be caused by press-fitting is prevented.Type: GrantFiled: January 30, 2014Date of Patent: December 6, 2016Assignee: NTN CORPORATIONInventors: Kouyou Suzuki, Hiroshi Niwa, Fuminori Satoji, Kimihiko Bito, Yoshiharu Inazuka

Publication number: 20160348750Abstract: A base isolator according to an embodiment is provided between an object to be base-isolated and a foundation, and has an elastic body expanding and contracting to reduce horizontal vibrations generated in the object. The base isolator includes: an anchored portion anchored to the foundation; a base-isolation unit having the elastic body and provided on the anchored portion; a first anchoring groove provided on a first surface which is a surface of the base-isolation unit facing the anchored portion; a second anchoring groove provided on a second surface which is a surface of the anchored portion facing the base-isolation unit. An anchor simultaneously fits into the first and second anchoring grooves such that a horizontal movement of the base-isolation unit with respect to the foundation is restricted. The anchor removes restriction on the horizontal movement of the base-isolation unit when a predetermined force is applied in a horizontal direction.Type: ApplicationFiled: August 11, 2016Publication date: December 1, 2016Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Gaku NAKAMURA, Hiroshi Niwa, Tomokazu Higuchi

Patent number: 8282282Abstract: A motion guide device is able to damp a moving block from vibrating in a direction perpendicular to an axis of a raceway rail. A damping plate with a surface facing a surface of a raceway is provided at a moving block body. The surface of the damping plate is set to be in contact with the raceway rail or is set such that a gap between its surface of the raceway rail is as close to zero as possible. When vibration occurs from the raceway rail or the moving block, the surface of the raceway rail and the surface of the damping plate come into contact with each other. This brings about change in a spring constant of the motion guide device in the direction perpendicular to the axis of the raceway.Type: GrantFiled: May 23, 2006Date of Patent: October 9, 2012Assignee: THK Co., Ltd.Inventors: Hidekazu Michioka, Hiroshi Niwa, Hiroaki Mochizuki, Takuya Yamagata, Takuya Horie
