Patent number: 5126645Abstract: A grinder robot having a grinder can be operated by both of a force control and a position control to grind a workpiece surface quickly and acccurately. When the grinder has not reached a target grinding point position to finish grindings, force loop drive control means are selected to drive the grinder in order to grind a work by a force control. After a grinding point ground by the grinder has reached the target position, then, position drive control means are selected to drive the grinder by a position control in order to execute precise grindings. A grinding amount in every grinding in a force control area is relatively large and a grinding speed in every grinding in a position control area is relatively fast. As a result, a workpiece can be ground quickly and accurately by the grinder robot.Type: GrantFiled: September 28, 1990Date of Patent: June 30, 1992Assignee: Kabushiki Kaisha ToshibaInventors: Takashi Yoshimi, Makoto Jinno

Patent number: 5075746Abstract: A thin film field effect transistor comprising a source electrode and a drain electrode joined to a first semiconductor layer respectively through first and second portions of a second doped semiconductor layer, a gate insulating layer, and a gate electrode capacity-coupled through the gate insulating layer with a portion of the first semiconductor layer, in which a channel is formed, corresponding to a gap between the source electrode and the drain electrode. A doped intermediate semiconductor layer is formed in contact with the channel in the first semiconductor layer. The gate threshold voltage of the thin film field effect transistor can be varied by selectively varying the thickness of the doped intermediate semiconductor layer. Thus, a plurality of thin film field effect transistors respectively having different gate threshold voltages can be formed on a single substrate simply by forming the doped intermediate semiconductor layers for the thin film field effect transistors with different thicknesses.Type: GrantFiled: July 14, 1989Date of Patent: December 24, 1991Assignees: Agency of Industrial Science and Technology, Taiyo Yuden Co., Ltd.Inventors: Yutaka Hayashi, Mitsuyuki Yamanaka, Takashi Yoshimi
