Publication number: 20110258648Abstract: Provided is a high-accuracy optical pickup supporting device by fixing guide shafts to a chassis by use of adjustment screws accurately. To this end, in the optical pickup supporting device, an end portion of a second guide shaft for supporting an optical pickup device is fixed to the chassis by use of: a coil spring included in an accommodation area of the chassis; and an adjustment screw. In addition, the adjustment screw is screwed to a fixation plate accommodated in an accommodation part of the chassis. Accordingly, a repulsive force produced by the coil spring does not concentrate on any part of the chassis. For this reason, the chassis is prevented from deforming and breaking due to this repulsive force.Type: ApplicationFiled: April 13, 2011Publication date: October 20, 2011Applicant: SANYO Electric Co., Ltd.Inventors: Takeshi AOKI, Hisayuki Itoh, Hidetoshi Akimoto, Masao Honda

Patent number: 7841840Abstract: A mechanism for drawing in refrigerant to front compression chambers (28a) of a double-headed piston type compressor differs from a mechanism for drawing in refrigerant to rear compression chambers (29a). More specifically, the mechanism for drawing in refrigerant to the front compression chambers (28a) include suction valves (18a) configured by flap valves. The mechanism for drawing in refrigerant to the rear compression chambers (29a) is configured by a rotary valve (35). Thus, pulsation of the compressor is reduced, so that the generation of noise is suppressed. As a result, a quiet compressor is achieved.Type: GrantFiled: October 17, 2006Date of Patent: November 30, 2010Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Shinichi Sato, Masahiro Kawaguchi, Jun Kondo, Takeshi Aoki, Tomohiro Wakita, Mitsuyo Ishikawa, Akio Saiki
