Patent number: 11807077Abstract: An air-conditioning register includes: a movable fin; an operation knob; and a transmission mechanism. A load generating mechanism is provided in a middle of a force transmission path in the transmission mechanism. The load generating mechanism includes a pressure receiving portion, a pressing member, and a spring. The pressure receiving portion has a pressure receiving surface. The pressing member rotates with respect to the pressure receiving portion as the operation knob rotates. The spring generates a load between the pressing member and the pressure receiving portion by urging the pressing member toward a side approaching the pressure receiving surface and pressing the pressing member against the pressure receiving surface. The pressing member and the pressure receiving portion are each formed of a hard resin material, and the pressing member is directly in contact with the pressure receiving surface to generate the load.Type: GrantFiled: August 23, 2021Date of Patent: November 7, 2023Assignee: TOYODA GOSEI CO., LTD.Inventors: Hiroto Watanabe, Hitoshi Fujisawa, Tatsuya Tanikawa

Patent number: 11400466Abstract: To improve actual coating efficiency, the present invention has a coating robot provided with a coating unit configured by a plurality of rotary atomizing type electrostatic coating machines horizontally arranged, and a coating control apparatus that controls the coating unit and the coating robot. A diameter of each of bells is 50 mm or less. The coating material discharge amount of each rotary atomizing type electrostatic coating machine is 400 cc/min or less. A coating distance between each bell and a surface to be coated of a workpiece is controlled between 50 mm to 150 mm. The coating material discharge amounts of the plurality of electrostatic coating machines are controlled for the respective coating machines. The control of the coating material discharge amounts includes a pause of coating material discharge.Type: GrantFiled: April 15, 2016Date of Patent: August 2, 2022Assignee: Ransburg Industrial Finishing K.K.Inventors: Akihiko Arichi, Tatsuya Tanikawa, Masato Miura, Osamu Yoshida, Yoshiji Yokomizo, Naohiro Masuda

Patent number: 11254191Abstract: An air conditioning register includes: a downstream side fin; an upstream side fin; an operation knob; and a fork including a pair of transmission pieces, and connected to the operation knob. A transmission shaft is provided in the upstream side fin, and is interposed between the pair of transmission pieces. The transmission shaft is provided with a stopper that regulates further displacement of the fork. A surface of the stopper is an inclined surface that is inclined with respect to a center axis of the transmission shaft so as to be located outside in a radial direction centering on the center axis of the transmission shaft as approaching an end of the transmission shaft. An inclination angle of the inclined surface with respect to the center axis of the transmission shaft is an angle equal to or greater than 9° and equal to or less than 14°.Type: GrantFiled: July 10, 2020Date of Patent: February 22, 2022Assignee: TOYODA GOSEI CO., LTD.Inventors: Kenichi Ito, Tatsuya Tanikawa, Yasuyuki Mitsui
