Patent number: 6816754Abstract: A method and system for controlling drive of a robot having two or more drive axes and driven in accordance with an action program transmitted from a system controller to a robot controller by a wireless transmission way, checks whether a detected current position of the robot coincides with a predetermined start position of the robot in terms of the drive axes, and allows the robot to be driven in accordance with the designated action program when the detected current position coincides with the predetermined start position. Failure in the position control of the robot due to transmission error is prevented by the position checking.Type: GrantFiled: November 12, 2002Date of Patent: November 9, 2004Assignee: Giken Co., Ltd.Inventors: Kazuo Mukai, Saburo Ashihara, Noboru Maruyama

Patent number: 6243067Abstract: A liquid crystal projector that has a plurality of light sources for providing light to a light crystal panel, which functions as an image forming unit in the projector. A plurality of light source driving power sources are connected to the plural light sources individually by means of a light source lighting control circuit. As the light source lighting control circuit, a delay circuit, a counter circuit, or a programmed microcomputer is used. By controlling the light source driving power sources, each one of the plural light sources lights up sequentially or alternately in time. The light emitted from the light sources is modulated by the liquid crystal panel to produce a light image, and the light image is projected through the projector lens.Type: GrantFiled: May 1, 1997Date of Patent: June 5, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Toshiyuki Noguchi, Kazuo Mukai
