Patent number: 10753323Abstract: An intake and exhaust system of an engine is provided, which includes an exhaust gas recirculation (EGR) passage configured to recirculate a portion of exhaust gas as EGR gas, from an exhaust passage of the engine to an intake passage, and an EGR cooler disposed in the EGR passage, the EGR cooler being coupled to a passage wall of the exhaust passage at an EGR gas inlet side, and having a center line intersecting with a flow direction of exhaust gas in the exhaust passage. A through-hole communicating the EGR cooler with the exhaust passage is formed into a long hole elongated in the flow direction in the exhaust passage.Type: GrantFiled: December 13, 2018Date of Patent: August 25, 2020Assignee: Mazda Motor CorporationInventors: Hisayoshi Yamada, Yuji Kojima

Patent number: 10408120Abstract: An opening/closing valve structure for an engine is provided with a valve body for opening and closing an intake passage or an exhaust passage of the engine; a pair of bush members mounted on axial ends of the valve body; and a shaft member axially passing through one of the bush members and projecting from the bush member by a predetermined length within one end of the valve body. Each of the bush members is mounted in such a manner that a part of the bush member is axially received in an end of the valve body and the remaining part thereof axially projects from the end of the valve body. A portion of the shaft member projecting from the one of the bush members is connected to the valve body in such a manner that relative rotation of the shaft member with respect to the valve body is disabled.Type: GrantFiled: August 10, 2015Date of Patent: September 10, 2019Assignee: MAZDA MOTOR CORPORATIONInventors: Einosuke Suekuni, Masaaki Sato, Junji Umemura, Shuhei Tsujita, Hisayoshi Yamada

Publication number: 20190234350Abstract: An intake and exhaust system of an engine mounted on a vehicle is provided, which includes an intake passage and an exhaust passage, and an exhaust gas recirculation (EGR) passage configured to introduce a portion of exhaust gas to the intake passage as EGR gas. The exhaust passage includes an exhaust gas purifier including an inlet part and an outlet part for the exhaust gas, that is disposed so that the exhaust gas flows horizontally, a branch connected to the outlet part and configured to branch in vehicle up-and-down directions a channel of the exhaust gas after being purified by the exhaust gas purifier, and a guide connected to the branch and configured to guide the exhaust gas below the outlet part. The EGR passage is connected to the branch and guides the EGR gas upward.Type: ApplicationFiled: January 10, 2019Publication date: August 1, 2019Inventors: Hisayoshi Yamada, Yuji Kojima

Patent number: 4611248Abstract: A rotary recording medium recorded with an information signal including a video signal along a spiral track thereon, and from which the recorded information signal is reproduced by a reproducing apparatus in which a reproducing element scans over the spiral track, is further recorded with a stop signal on a track turn recorded with an information signal which is to be reproduced repeatedly for a predetermined time period so that the reproducing element repetitively reproduces the track turn for the predetermined time period. The reproducing apparatus comprises a stop signal detection circuit for detecting the stop signal from a signal reproduced by the reproducing element, and a circuit responsive to the stop signal detected by the stop signal detection circuit, for causing repetitive reproduction of a predetermined track turn recorded with the stop signal. The still picture reproduction is performed by repetitively reproducing the information signal recorded on a track turn recorded with the stop signal.Type: GrantFiled: July 24, 1985Date of Patent: September 9, 1986Assignee: Victor Company of Japan, Ltd.Inventors: Yoshihiko Honjo, Hisayoshi Yamada, Kazuhiro Hosono, Masaki Sakurai, Ryozo Abe, Kenji Yoshihara
