Publication number: 20170159854Abstract: A resin-made pipe joint enhancing sealing property between a joint body and a sleeve. The joint body and the sleeve are produced by using a fluorine resin. A sealing portion which seals between the inner circumferential surface of an inserting portion of the sleeve and the outer circumferential surface of the inner cylinder portion is formed by press-inserting the inserting portion into a groove portion of the joint body. When, with respect to the inserting and groove portions, an insertion rate of the inserting portion to the groove portion is indicated by X, and a multiplying factor of the radial width of the inserting portion to the radial width of the groove portion is indicated by Y, the resin-made pipe joint has the insertion rate and multiplying factor which are within a range defined by following Expressions (1) and (2): Y=?0.218X+1.218??(1) and Y=?0.67X+1.67.Type: ApplicationFiled: September 17, 2015Publication date: June 8, 2017Applicant: Nippon Pillar Packing Co., Ltd.Inventors: Makoto FUJII, Masaki MIYAMOTO, Toshihide IIDA, Tomoyuki KOIKE, Atsushi NAKANO, Daisuke URATA

Publication number: 20170146161Abstract: A resin-made pipe joint with enhanced sealing property between a joint body and sleeve. A sealing portion which seals between an inner circumferential surface of an inserting portion of a sleeve and an outer circumferential surface of an inner cylinder portion is formed by press-inserting an inserting portion into a groove portion of the joint body. When the inserting portion is press-inserted into the groove portion, a space is formed between a body cylinder portion located opposite to an opening portion of the groove portion in the axial direction, and the projection end of the inserting portion. After completing press insertion of the inserting portion into the groove portion, in a section including axis of the inner cylinder portion, a region in the outer circumferential surface of the inner cylinder portion facing the space forms an angle of 5° to 15° to the axis of the inner cylinder portion.Type: ApplicationFiled: September 17, 2015Publication date: May 25, 2017Applicant: Nippon Pillar Packing Co., Ltd.Inventors: Makoto FUJII, Masaki MIYAMOTO, Toshihide IIDA, Tomoyuki KOIKE, Atsushi NAKANO, Daisuke URATA

Patent number: 9346463Abstract: During engine startup and engagement of a transmission clutch in response to an EV?HEV mode-switch demand, the transmission clutch is engaged, which precedes initiation of self-sustaining running by the engine. During the clutch engagement, high engine torque is not input to the transmission clutch, and no large torque differential arises in relation to the torque at the output side of the transmission clutch, which during EV operation is a low value about equal to the low motor torque of an electric motor. Additionally, due to cranking during engine startup, the input/output rotation difference of the transmission clutch is small, and when the transmission clutch is engaged, engagement of the transmission clutch may be carried out with reduced shock, as the input/output torque differential and the input/output rotation difference are small.Type: GrantFiled: November 25, 2013Date of Patent: May 24, 2016Assignee: Nissan Motor Co., Ltd.Inventors: Tomoyuki Koike, Kengo Kubo, Yoshiaki Kato

Patent number: 8861621Abstract: In a receiver circuit, a binary signal is generated based on a signal level of a received signal that has been received via a transmission line from a driver of a transmitter circuit. Then, a first stable state and a second stable state are detected based on a reference signal whose signal level changes in accordance with the received signal. In the first stable state, the received signal is stable at a first signal level. In the second stable state, the received signal is stable at a second signal level. When the first stable state is detected and the received signal is changed from the first signal level into the second signal level, the generated binary signal is retained at a signal level corresponding to the second signal level, until the second stable state is detected.Type: GrantFiled: August 22, 2013Date of Patent: October 14, 2014Assignee: Denso CorporationInventors: Hiroyuki Mori, Naoki Kamikawa, Masayoshi Satake, Tomohisa Kishigami, Tomoyuki Koike
