Publication number: 20190226432Abstract: An intake manifold for an internal combustion engine includes a plurality of pieces joined with each other at a linearly extending joint. The pieces include a first piece and a second piece. The joint of the first piece and the second piece includes a first portion and a second portion excluding the first portion. The intake manifold is configured so that the first portion is opposed to a fuel system component of the internal combustion engine when the intake manifold is coupled to the internal combustion engine. A force required to separate the second piece from the first piece is referred to as a joining force. The joining force at the first portion is greater than the joining force at the second portion.Type: ApplicationFiled: January 4, 2019Publication date: July 25, 2019Inventors: Atsushi MIZUGUCHI, Ryo IKEGAMI

Patent number: 9567959Abstract: Provided is a connector which can facilitate tuning of frequency of pulsation to be reduced and prevent sealing performance from degrading when a piston moves. A pulsation reducing member adopts a structure in which the piston moves in a cylinder. The cylinder has an annular flange portion projecting in a radially inner direction of a hollow cylindrical shape. An elastic sealing member is sandwiched in a compressed state between an end surface of the flange portion of the cylinder and an end surface of the piston. An urging body is disposed in a region in the cylinder on a side of the piston opposite to a passage and applies urging force to move the piston toward the passage and compress the elastic sealing member.Type: GrantFiled: June 6, 2014Date of Patent: February 14, 2017Assignee: SUMITOMO RIKO COMPANY LIMITEDInventors: Yorihiro Takimoto, Ryo Ikegami, Koji Mizutani, Kazutaka Katayama

Patent number: 8653535Abstract: A semiconductor device according to the present invention includes a contact region 201 of a second conductivity type which is provided in a body region 104. The contact region 201 includes a first region 201a in contact with a first ohmic electrode 122 and a second region 201b located at a position deeper than that of the first region 201a and in contact with the body region 104. The first region 201a and the second region 201b each have at least one peak of impurity concentration. The peak of impurity concentration in the first region 201a has a higher value than that of the peak of impurity concentration in the second region 201b.Type: GrantFiled: August 29, 2011Date of Patent: February 18, 2014Assignee: Panasonic CorporationInventors: Chiaki Kudou, Masahiko Niwayama, Ryo Ikegami

Patent number: 8596690Abstract: A quick connector capable of surely confirming that a pipe body is engaged by a retainer when an elastically-deformable claw of the retainer and an elastically-deformable claw of a checker are adjacently arranged in an axial direction. Checker-axis direction elastically-deformable claws have distal-end sides formed flexibly deformable in the axial direction, maintain a state of being engaged by a second engagement portion of a retainer body by having deflective deformation regulated by a retainer diameter-expanding elastically-deformable claw in a state in which the retainer diameter-expanding elastically-deformable claw is expanded diametrically, and regulate sliding from a first position with respect to the retainer body toward a set radial direction by being engaged by the second engagement portion of the retainer body.Type: GrantFiled: February 5, 2013Date of Patent: December 3, 2013Assignee: Tokai Rubber Industries, Ltd.Inventors: Hiroshi Yamada, Kazushige Sakazaki, Takahiro Shibata, Ryo Ikegami, Hisashi Terayama
