Patent number: 8502489Abstract: A motor control device, which receives at least two emergency stop signals, includes an LSI, a PWM signal transmission circuit, a drive circuit, and an inverter circuit. The LSI generates PWM signals. The PWM signal transmission circuit transmits the PWM signals. The drive circuit generates inverter drive signals. The inverter circuit includes a P-side power switching device and an N-side power switching device. The drive circuit includes a P-side drive circuit for driving the P-side power switching device, and an N-side drive circuit for driving the N-side power switching device. One of the emergency stop signals is inputted to the P-side drive circuit and the PWM signal transmission circuit. The other emergency stop signal is inputted to the N-side drive circuit and the PWM signal transmission circuit. In response to the receipt of an emergency stop signal, the PWM signal transmission circuit stops transmitting the PWM signals, and the drive circuit stops outputting the inverter drive signals.Type: GrantFiled: October 13, 2009Date of Patent: August 6, 2013Assignee: Panasonic CorporationInventors: Hisashi Ooto, Taro Kishibe, Hiroshi Ozaki, Ryuhei Watabe, Satoru Doi

Publication number: 20060213872Abstract: An object of the present invention is to provide an arcing horn system having a highly efficient dynamic current shutoff property including a dynamic current shutoff capability, for example, enough for the short circuit fault and other object thereof is to provide an arcing horn system capable of repeatedly maintaining the good dynamic current shutoff capability. In an arcing horn system, an insulative tube 21 for surrounding a front end side of an arcing horn 11, 12 is provided and an air vent 21a communicating from a front end portion of the arcing horn 11, 12 to a front end surface of the insulative tube 21 is formed on the insulative tube 21, so that the arc jet is blown off from the air vent 21a upon the flashover in accordance with the thunder stroke. The insulative tube 21 is made of a polyamide resin. A cap 30 for covering the front end side of the insulative tube 21 is disposed so as to prevent the intrusion of the rain water into the air vent 21a.Type: ApplicationFiled: September 13, 2002Publication date: September 28, 2006Inventors: Kazuhiko Takasu, Takashi Chino, Osamu Usuda, Toshio Watanabe, Tomoyasu Hasegawa, Kazuhiko Shimoda, Satoru Doi, Takehiko Kikuchi, Katsuyuki Urasawa, Hiroaki Kanatsuji, Yoshihiko Ota, Hiroki Sakamoto, Ryoji Matsushita
