Patent number: 9370848Abstract: In judging loosening of a crew, a measuring section measures a position of a bit as a relative position in relation to a placement surface of a screw supplying device when the screw is acquired from the screw supplying device. The measuring section also measures the position of the bit as a relative position in relation to a workpiece surface when fastening of the screw onto a workpiece has been completed. A judging section judges that screw loosening has not occurred when, based on the first and second bit positions, a difference between the first and second bit positions falls within an allowable range. The judging section judges that screw loosening has occurred when the difference does not fall within the allowable range.Type: GrantFiled: September 11, 2012Date of Patent: June 21, 2016Assignee: DENSO WAVE INCORPORATEDInventor: Toyoo Harada

Publication number: 20030128499Abstract: An electrical double layer capacitor which causes no liquid leakage and capacity decrease due to the side reactions of the electrolyte and has a very low leak current. It holds an electrolyte which contains the supporting salt in such an amount that the ionized supporting salt in the electrolyte mostly migrates close to the surface of the electrode in the fully charged state, so that the electrolyte becomes almost an insulator when the electrical double layer has been formed by full charging. In addition, the positive electrode has a smaller capacity than the negative electrode, so that the capacitor has a high withstanding voltage.Type: ApplicationFiled: August 6, 2002Publication date: July 10, 2003Inventors: Shunji Watanabe, Hideharu Onodera, Tsugio Sakai, Toyoo Harada, Yoshimi Kanno, Shinichi Takasugi, Tsuneaki Tamachi
