Patent number: 10465599Abstract: A turbocharger includes a bearing portion having an end as an inner end surface located within a turbine housing in a penetrating direction of a bearing hole; a shaft rotatably supported in the bearing hole, one end thereof located within the turbine housing and the other end thereof located outside the turbine housing; an attaching plate fixed to the shaft, including an inner facing surface facing the inner end surface in an axial direction of the shaft; and a valve coupled to the shaft via the attaching plate to open and close a flow path opened to an internal space of the turbine housing. An inner radial groove is formed in at least one of the inner end surface and the inner facing surface. The inner radial groove extends in the radial direction of the shaft to allow a part of an exhaust gas flowing within the turbine housing to flow therethrough.Type: GrantFiled: December 9, 2016Date of Patent: November 5, 2019Assignee: IHI CorporationInventors: Yuusuke Isono, Kiyomichi Ichikawa, Atsushi Mori, Yuji Kobayashi, Kazuaki Iwata

Patent number: 10408085Abstract: A turbocharger includes: a turbine housing including an internal space formed therein; a bearing portion provided in the turbine housing; a shaft rotatably inserted into a bearing hole in a state where at least one end protrudes more to an inside of the turbine housing than the bearing portion; and a valve fixed to the shaft and configured to open and close a flow path opened to the internal space. The bearing portion includes a protrusion portion which protrudes from an inner wall of the turbine housing. The radial hole of the protrusion portion penetrates the bearing portion in a radial direction of the shaft, from the outer circumferential surface of the bearing portion to the bearing hole.Type: GrantFiled: November 28, 2016Date of Patent: September 10, 2019Assignee: IHI CorporationInventors: Yuusuke Isono, Kiyomichi Ichikawa, Atsushi Mori, Yuji Kobayashi, Kazuaki Iwata

Patent number: 5183249Abstract: A paper conveyor for conveying paper includes a conveyor roll for conveying paper, a drive motor for driving and rotating the conveyor roll, a rotary follower roll for pressing onto the conveyor roll and for holding a paper and a convey direction switch mechanism for switching the conveying direction of the paper. The paper is conveyed in a predetermined direction by the conveyor roll and the rotary follower roll. When the conveying direction of the paper is changed to an opposite direction, the convey direction switch mechanism is adapted to control the follower roll so that the follower roll can be rocked from one direction to another with its axis of rocking coinciding with an axis of the conveyor roll. Therefore, the conveying direction of the paper can be changed very smoothly.Type: GrantFiled: August 30, 1990Date of Patent: February 2, 1993Assignee: Auto-Stamp Institute Inc.Inventor: Kiyomichi Ichikawa

Patent number: 4274624Abstract: A dual-mode sheet sorting apparatus for sorting plural sheets into plural storage bins according to a predetermined order. The apparatus includes first bin members for storing sorted sheets, movable second bin members for storing sorted sheets and having a number corresponding to the number of the first bin members, and selecting device for selectively placing the second bin members in a storage position for receiving the sheets or in a retracted position in which the second bin members are retracted from the storage position, such that in a first operation mode the second bin members are displaced to the retracted position by the selecting device to allow sheet sorting into the first bin members, while in a second operation mode the second bin members are displaced to the storage position by the selecting device to allow sheet sorting into the second bin numbers in preference to the first bin members.Type: GrantFiled: October 30, 1979Date of Patent: June 23, 1981Assignee: Canon Kabushiki KaishaInventors: Tadashi Sato, Shigeru Yoshimura, Kiyomichi Ichikawa
