Publication number: 20240139716Abstract: Provided is an exhaust gas purification catalyst providing a catalyst performance and an OSC performance at the same time even at low temperature. The present disclosure relates to an exhaust gas purification catalyst including a substrate and a catalyst coating layer coated on the substrate. The catalyst coating layer includes a first catalyst coating layer containing Pd and/or Pt and a second catalyst coating layer containing Rh. The first catalyst coating layer is formed from an end portion in an upstream side with respect to an exhaust gas flow direction in the exhaust gas purification catalyst. The second catalyst coating layer includes an upstream coating layer and a downstream coating layer. Rh in the upstream coating layer and the downstream coating layer are supported on specific carrier particles. Further, a particle diameter of Rh is controlled.Type: ApplicationFiled: October 17, 2023Publication date: May 2, 2024Applicants: Toyota Jidosha Kabushiki Kaisha, Cataler CorporationInventors: Takahiro NISHIO, Nobuyuki Takagl, Takumi Tojo, Shogo Shirakawa, Kengo Shimizu, Sho Hoshino, Shun Sakamoto, Yosuke Toda

Patent number: 10543811Abstract: A wiper system performs operation control on wiper driving electric motors and based on position information about wiper blades and attached to pivot shafts, wherein a learning mode in which a position of the wiper blades is learned to correct blade position information is executed after the wiper blades are attached to the pivot shafts, respectively. In the learning mode, the wiper blades are moved to a prescribed position such as a lower retracted position, and that the wiper blades are located in the prescribed position is detected by such means as a sensor, a video image, and contact with a jig. If the wiper blades are detected to be in the prescribed position, the blade position information is corrected to a value corresponding to the position.Type: GrantFiled: November 5, 2015Date of Patent: January 28, 2020Assignee: MITSUBA CORPORATIONInventors: Tetsuya Koike, Ken Hirata, Kengo Shimizu

Patent number: 6797092Abstract: A method for manufacturing a monolithic ceramic electronic component formed by using a laminate allows a plurality of types of ceramic green sheets to be laminated with ease and efficiency. The method enables a reduction in space for lamination. This method includes first, a ceramic green sheet with a predetermined shape is cut out of a long first ceramic green sheet supported on a carrier film by a cutting/laminating head. The cut-out ceramic green sheet is laminated to the cutting/laminating head. A card-like second ceramic green sheet supported on a carrier film is cut by a cutting/laminating head. The cut ceramic green sheets is laminated to the cutting/laminating head. A laminate is formed by performing each of the first and second steps plural times.Type: GrantFiled: April 26, 2002Date of Patent: September 28, 2004Assignee: Murata Manufacturing Co., Ltd.Inventors: Yoshinori Sakamoto, Kengo Shimizu
