Patent number: 11827985Abstract: A film forming method forms a coating film on a workpiece (e.g., a cylinder head) having a film-deposited portion (e.g., an annular valve seat part) by moving a nozzle of a cold spray device relative to the workpiece along a film formation trajectory having a film formation starting point and a film formation finishing point in which the film-deposited portion overlaps to form an overlapping portion. The coating film is formed by causing a raw material powder to collide in a solid-phase state with the workpiece and plastically deform. Also, the coating film on the film-deposited portion is further formed such that an inclination angle of an end part of the coating film relative to a surface of the film-deposited portion is 45° or less at the film formation starting point of the overlapping portion.Type: GrantFiled: March 29, 2019Date of Patent: November 28, 2023Assignee: Nissan Motor Co., Ltd.Inventors: Koukichi Kamada, Hirohisa Shibayama, Naoya Tainaka, Yoshito Utsumi, Hidenobu Matsuyama, Eiji Shiotani, Toshio Ogiya, Haruhiko Suzuki

Publication number: 20220154344Abstract: A film forming method forms a coating film on a workpiece having at least two film-deposited portions which are not continuous with each other by moving a nozzle of a cold spray device relative to each other along a continuous movement trajectory. The movement trajectory includes at least two trajectories corresponding to the film-deposited portions and a connecting trajectory linking the trajectories of the film-deposited portions. The film-deposited portions are formed by continuously spraying a raw material powder from the nozzle by cold spraying to form a coating film on each of the plurality of film-deposited portions. A turnback point of the spraying is set on the connecting trajectory where a relative speed between the workpiece and the nozzle decreases in the movement trajectory.Type: ApplicationFiled: March 29, 2019Publication date: May 19, 2022Inventors: Hirohisa SHIBAYAMA, Koukichi KAMADA, Naoya TAINAKA, Yoshito UTSUMI, Hidenobu MATSUYAMA, Eiji SHIOTANI, Toshio OGIYA, Haruhiko SUZUKI

Patent number: 11292207Abstract: A joined body includes: a first member having a hole; and a second member that is press-fitted to the hole. The second member has a second abutment surface abutting against a first abutment surface which is an inner wall of the first member forming the hole. A groove portion is defined on one of an inner wall of the first member and an outer wall of the second member, and has a groove formed to extend in a press-fitting direction of the second member to the first member. An insertion portion is formed to protrude in a radial direction from the other of the inner wall of the first member and the outer wall of the second member, and is inserted in the groove. The groove portion has an engagement portion that is able to be engaged with an end portion of the insertion portion in the press-fitting direction.Type: GrantFiled: April 5, 2016Date of Patent: April 5, 2022Assignee: DENSO CORPORATIONInventors: Hidekazu Watanabe, Haruhiko Suzuki, Takehiro Saito

Patent number: 10860047Abstract: An accelerator device includes a pedal pad and a strain gauge. When a driver of a vehicle having the accelerator device depresses the pedal pad, the pedal pad is deformed in a direction of a blank arrow. The strain gauge senses the displacement amount of the pedal pad in the direction of the blank arrow and outputs an electric signal, which corresponds to the displacement amount, to an outside as the depression amount of the accelerator device. When the driver removes a foot from the pedal pad, the pedal pad returns to a state of the pedal pad that is not depressed by the driver. Therefore, it is possible to limit occurrence of that the depression amount of the pedal pad becomes an unintended value due to, for example, catching of the pedal pad by a floor mat. As a result, the accelerator device can reliably sense the depression amount.Type: GrantFiled: March 22, 2019Date of Patent: December 8, 2020Assignee: DENSO CORPORATIONInventors: Noriyasu Kihara, Haruhiko Suzuki
