  • Patent number: 11807077
    Abstract: 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.

  • Patent number: 11400466
    Abstract: 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.

  • Patent number: 11254191
    Abstract: 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°.

  • Patent number: 11192127
    Abstract: In an electrostatic atomization coating apparatus including a nozzle head including a plurality of coating material ejection ports; a coating material chamber that is provided inside the nozzle head and to which a coating material is supplied via a coating material supply path, each of the coating material ejection ports being in communication with the coating material chamber via an individual branch coating material path; and a voltage application device that provides a potential difference between the nozzle head and an object to be coated, the coating material ejected from each of the coating material ejection ports via the coating material supply path, the coating material chamber, and the branch coating material path being brought into a charged state through application of a voltage by the voltage application device, an open/close valve device that opens and closes all of the branch coating material paths, or opens and closes a specific subset of a plurality of branch coating material paths out of all
