Patent number: 11527763Abstract: A manufacturing method for a catalyst layer for a fuel cell includes: preparing a nozzle group to output ultrasonically-vibrated air, the nozzle group being formed of an aggregate of unit nozzles each controlled in at least one of the temperature of the ultrasonically-vibrated air to be output from the unit nozzle, an internal pressure in the unit nozzle, and the position of the unit nozzle in an output direction in which the ultrasonically-vibrated air is to be output; coating a sheet-like base material with catalyst ink containing a solvent, an ionomer, and a catalyst supporting material on which a catalyst is supported; and drying the catalyst ink by blowing the ultrasonically-vibrated air from the nozzle group on the catalyst ink applied to the base material. The drying includes controlling at least one of the temperature, the internal pressure, and the position for each of the unit nozzles independently.Type: GrantFiled: March 19, 2021Date of Patent: December 13, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kazuomi Yamanishi, Joji Yoshimura

Patent number: 10570497Abstract: There is provided a surface treatment method in which a processing gas is brought in contact with a heated processing object made of steel, an element in the processing gas is solid-solutionized, and thus a surface treatment is performed on the processing object. The processing object is heated to a heating temperature in a vicinity of a processing temperature at which the surface treatment is performed by heating an atmosphere in which the processing object is disposed. The surface treatment is performed by bringing the processing gas in contact with a surface of the processing object while the processing object which is heated is directly heated to the processing temperature.Type: GrantFiled: June 14, 2017Date of Patent: February 25, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroyuki Inoue, Kazuomi Yamanishi, Shinnichi Hiramatsu, Izuru Yamamoto

Patent number: 8986619Abstract: Disclosed is an exhaust air purification device, which enables heating a carrier uniformly and heating a catalyst supported on the carrier above an active temperature thereof even when an engine is run on a cold-start mode. Specifically disclosed is an exhaust air purification device, which includes a hollow case as an exterior, a cylindrical carrier housed in the case and having a catalyst supported thereon, and a pair of electrodes arranged on the outer circumferential surface of the carrier. In the device, the carrier is electrically heated through the pair of electrodes so that the catalyst is heated to an active temperature thereof. In the device, each of the pair of electrodes is placed on an arc-shaped outer circumferential segment of the carrier that has a central angle of 20 to 40 degrees, and the electrodes are opposed to each other with the phase difference of 180 degrees.Type: GrantFiled: October 30, 2009Date of Patent: March 24, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kinoshita Yasuo, Tadashi Takagaki, Kazuomi Yamanishi, Takayoshi Doi, Tatsuo Iida
