Patent number: 11592038Abstract: Provided is a regulator unit that when a pressure is set with respect to a workpiece having a certain weight, can be used for raising/lowering, suspension, or the like of a workpiece having a weight exceeding the weight with the set pressure maintained. The regulator unit is disposed between a drive cylinder and a fluid pressure source and includes a regulator body and a pressure control mechanism connected to the regulator body. The pressure control mechanism includes a cylindrical housing, an end surface cover, and an operation handle fixed to an end of a screw rod protruding from the end surface cover. The end surface cover is fixed to a resin ring fitted to an end of the cylindrical housing and is slidingly rotatable with respect to the end surface of the cylindrical housing integrally with the resin ring in accordance with the amount of turn of the operation handle.Type: GrantFiled: March 11, 2022Date of Patent: February 28, 2023Assignee: TAIKOH CO., LTD.Inventor: Yasuharu Asai

Patent number: 8274807Abstract: A boost power module and an inverter form a semiconductor module. A smoothing capacitor is arranged outside the semiconductor module. A bus bar forming a power supply line is divided into bus bars, between which a lead member extending outward from the semiconductor module is coupled. The lead member has an electric contact with one of terminals of the capacitor arranged outside the semiconductor module. A bus bar forming an earth line is divided into bus bars, between which a lead member extending outward from the semiconductor module is coupled. The lead member has an electric contact with the other terminal of capacitor.Type: GrantFiled: February 12, 2008Date of Patent: September 25, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hisao Nishimori, Yasuharu Asai
