Patent number: 8711460Abstract: In a moving structure, stability of swing motion of a moving plate is increased by enhancing tensional rigidity or flexural rigidity while restraining torsion rigidity of the hinge units. The hinge units of ladder shape with honeycombed portions are formed by twin supporting rods and crosspieces bridged between the twin supporting rods so as to support the moving plate rotatably. The tensional rigidity or the flexural rigidity is increased while restraining the torsion rigidity of the hinge units by the honeycombed portions of the hinge units.Type: GrantFiled: June 24, 2009Date of Patent: April 29, 2014Assignee: Panasonic CorporationInventors: Hideki Ueda, Hiroshi Noge, Kiyohiko Kawano, Hiroaki Tachibana

Patent number: 8116506Abstract: Arrangement of an internal component (not shown) arranged in the vicinity of the top side is different from that of the hinge side of an image element protective screen (2). An actuator (5) is fixed to the top side of the image element protective screen (2) and an actuator (4) is fixed to the hinge side of the image element protective screen (2). Since Arrangement of the internal component in the vicinity of the actuator is different, different sound pressure frequency characteristics or the like are experienced when each actuator is driven independently. When the actuators (4, 5) are driven simultaneously, sound pressure frequency characteristics and vibration frequency characteristics can be flattened. Isolation between the vibration speed of a vibrator near one actuator and the vibration speed of a vibrator in the region near the other actuator that are produced by respective actuators is set at 10 dB or above.Type: GrantFiled: November 2, 2006Date of Patent: February 14, 2012Assignee: NEC CorporationInventors: Jun Kuroda, Hideki Ueda, Yukio Murata, Ukyo Mori, Yasuhiro Sasaki, Yasuharu Ohnishi

Publication number: 20110188104Abstract: In a semiconductor mechanical structure, hinges may not be broken even when a mechanical shock is applied from outside, and thus, crashworthy is enhanced. A light scanning mirror includes a moving plate, a twin hinges constituting an axis of swing motion of the moving plate wherein an end of each hinge is connected to both ends of the moving plate, a stationary frame which is disposed to surround peripheries of the moving plate and supports another end of each of the twin hinges, and stoppers formed on the stationary frame. When the moving plate displaces in a lateral direction, the stopper contacts a side end portion of a recess of the moving plate, so that the displacement of the moving plate in the lateral direction is restrained. Thereby, the breakage of the hinges is prevented even when the mechanical shock is applied from outside.Type: ApplicationFiled: June 25, 2009Publication date: August 4, 2011Applicant: PANASONIC ELECTRIC WORKS CO., LTD.Inventors: Hiroaki Tachibana, Hiroshi Noge, Kiyohiko Kawano, Hideki Ueda
