Publication number: 20150142156Abstract: There is provided a flexible manufacturing system that can reliably place a workpiece that isn't defective piece in a state where the workpiece will be machined again. After a pallet is conveyed to a standby position and before machining of the workpiece attached to the pallet is started, controllers determines whether machining of the workpiece with a corresponding machining device is possible. When it is determined that machining is possible, the controller starts machining with the machining device. When it is determined that machining is impossible, the controller make a conveyor convey the pallet from the standby position to a pallet storage room, and stores the machining status information on the conveyed pallet as the machining-waiting state.Type: ApplicationFiled: November 13, 2014Publication date: May 21, 2015Applicant: JTEKT CORPORATIONInventors: Katsuhiro MASEKI, Tatsuhiko INAGAKI, Takaaki SUGIURA, Kazuhiro TSUJIMURA

Patent number: 7095592Abstract: Disclosed is a head slider having excellent shock resistance, a head supporter, as well as a disk drive using the head slider. The head slider is characterized in a form of its opposite-to-disk surface, such that a fixed point is set at a position located outwardly of a rear end portion of the head slider and at a predetermined distance from a load application point, which load urges the slider toward a disk. When a shock force is externally applied to the head slider, the head slider is rotated about this fixed point such that at least one of pitch angle and roll angle is maintained positive. Because of this structure, a disk drive excellent in shock resistance can be provided.Type: GrantFiled: March 25, 2002Date of Patent: August 22, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshihiro Ueno, Tatsuhiko Inagaki, Zhi Sheng Deng

Patent number: 7057855Abstract: A head slider has, on its front face opposing a disk, a positive pressure generating section and a negative pressure generating recess, and a sloped face slopping toward the air outlet side. By virtue of the sloped face, the negative pressure hindering with high-speed unloading operation of the head slider can be decreased quickly. Thus, at the time of unloading, an additional load is not necessary for the suspension, and the stroke of the suspension for raising the head slider can be shortened. Therefore, a disk drive which is thinner, smaller, and capable of high recording density can be realized.Type: GrantFiled: December 6, 2001Date of Patent: June 6, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshihiro Ueno, Tatsuhiko Inagaki
