Patent number: 11421467Abstract: An opening-closing body controller includes a motor body that opens and closes an open-close body, a control unit that controls and drives the motor body, and an inner temperature detector that detects an inner temperature of the motor body. The control unit performs an entrapment detection process in a section excluding a mask section that is set from a fully closed position of the open-close body to a preset position in an opening direction of the open-close body. The control unit corrects the mask section in accordance with the inner temperature of the motor body detected by the inner temperature detector.Type: GrantFiled: January 22, 2020Date of Patent: August 23, 2022Assignee: DENSO CORPORATIONInventor: Tomohiko Kawaguchi

Publication number: 20190337366Abstract: An opening-closing body drive device includes a motor that opens and closes an opening-closing body; and a controller that controls driving of the motor. The controller recognizes an arrested position of the motor during a closing action as a reference position and performs an entrapment process in a section excluding a mask section from the reference position to a predetermined position toward an opening direction side. The controller updates the reference position when the arrested position of the motor is located toward a closing direction side of a set position, which is set in the mask section, and does not update the reference position when the arrested position of the motor is located toward an opening direction side of the set position.Type: ApplicationFiled: March 2, 2018Publication date: November 7, 2019Applicant: DENSO CORPORATIONInventors: Tomohiko KAWAGUCHI, Daisuke NISHIO, Tomoki YAMASHITA

Patent number: 10464399Abstract: A vehicle window opening device includes a controller, a change detector, and a drawing detector. The controller configured to control opening and closing of a vehicle window based on a drive force of a motor. The change detector is configured to detect a change in a state of movement of the vehicle window. A drawing detector is configured to detect drawing of a foreign matter by the vehicle window based on a change detected by the change detector. The controller is configured to restrict opening of the vehicle window after the drawing detection.Type: GrantFiled: January 28, 2016Date of Patent: November 5, 2019Assignee: Denso CorporationInventors: Daisuke Nishio, Tomohiko Kawaguchi, Masaru Kubota, Yutaka Naito

Patent number: 7206190Abstract: In an electrode for an electric double layer capacitor of the present invention, the peak value of particle size distribution of graphite particles added to a conductive adhesive is in a range of 2.6 to 3.2 ?m, not less than 100,000 dimples having a largest outer diameter in a range of 4 to 10 ?m and a depth in a range of 4 to 15 ?m are formed on the surface of the collector sheet per 1 cm2, and the occupied area of the dimples to the entire surface area of the collector sheet is not more than 50%. By determining the saponification value of polyvinylalcohol which is used as a binder component of the conductive adhesive in a range of 90.0 to 98.5, adhesiveness of the collector sheet and the electrode forming sheet is improved. Furthermore, by substituting H atoms contained in the polyvinylalcohol with Si atoms, adhesiveness of the collector sheet and the electrode forming sheet can be further improved.Type: GrantFiled: June 21, 2005Date of Patent: April 17, 2007Assignees: Honda Motor Co., Ltd., No-Tape Industrial Co., Ltd., Daido Metal Company Ltd.Inventors: Kenichi Murakami, Manabu Iwaida, Shigeki Oyama, Toshiaki Fukushima, Tomohiko Kawaguchi, Kouki Ozaki, Masanori Tsutsui
