Patent number: 6840642Abstract: A thermally actuated micro mirror includes a mirror surface, and a support structure section having a multilayer structure to support the mirror surface. The support structure section generates heat by the application of electricity thereto, and is deflected by a difference in coefficient of thermal expansion in the multilayer structure, thereby tilting the mirror surface at an arbitrary angle. The support structure section is disposed between the mirror surface and an electrode section for applying electricity. A longitudinal axis of the support structure section is perpendicular to the center axis of the mirror surface, and the longitudinal center of the support structure section is substantially placed on the center axis of the mirror surface. Therefore, the turning axis of the mirror surface is not displaced, and the light reflecting position does not move on the mirror surface.Type: GrantFiled: June 19, 2003Date of Patent: January 11, 2005Assignee: Sony CorporationInventors: Hiroichi Ishikawa, Kanji Yokomizo

Patent number: 4901181Abstract: A motor control device controls a motor driving mechanism which drives a motor according to a motor drive signal for providing a normal drive signal and a locked condition signal. When the motor becomes overloaded while being driven by the motor driving mechanism according to the motor drive signal, the motor driving mechanism is controlled by controlling circuitry which inhibits the motor drive signal from being supplied to the motor driving mechanism. The controlling circuitry, while the motor is in the overloaded state, controls the motor driving mechanism so that power is supplied intermittently to the motor, or so that the supply of power for the regular and reverse rotation is given alternately. The controlling circuitry, when the load of the motor becomes normal, allows driving of the motor according to the motor drive signal.Type: GrantFiled: February 9, 1989Date of Patent: February 13, 1990Assignee: Diesel Kiki Co., Ltd.Inventors: Choshich Miyanaga, Kanji Yokomizo
