Patent number: 7315502Abstract: An object of the present invention is to attain stable tracking servo performance by suppressing an offset caused by a shift of an object lens or a tilt of a disk, despite the one-beam method which does not cause reduction in light quantity of the main beam. A diffraction grating is provided between a hologram and a light receiving section, and a diffraction efficiency of the diffraction grating is varied in a grating longitudinal direction. For example, if an incident light beam on the diffraction grating is shifted in the grating longitudinal direction, the quantity of received light in each light receiving section varies to cause offset. By performing tracking servo so as to cancel the change, it is possible to correct the offset, thereby attaining stable tracking servo performance.Type: GrantFiled: November 5, 2002Date of Patent: January 1, 2008Assignee: Sharp Kabushiki KaishaInventors: Keiji Sakai, Takahiro Miyake, Tetsuo Ueyama, Renzaburo Miki, Hiroshige Makioka, Noboru Fujita, Osamu Miyazaki

Patent number: 7231648Abstract: To provide a disk supporting apparatus, a disk holding apparatus and a disk apparatus whose planar dimension is minimized, and which can be manufactured simply and inexpensively. A plurality of supporting portions 44 inclines with respect to a top portion 46 as a vertex. A tray 26 is formed into a substantially triangular pyramid (three-dimensional) configuration, and a planar dimension of the tray 26 can be smaller than that of a conventional turntable. Accordingly, a plurality of disks can be mounted on the tray 26. The supporting portion 44 of the tray 26 can be placed in parallel to a door leaf without a slide mechanism that has conventionally been used for sliding a tray. Accordingly, a desired disk can be attached/detached merely by rotating and driving the tray 26, and a mechanism disposed at a stereo apparatus is made compact and manufactured inexpensively.Type: GrantFiled: December 6, 2001Date of Patent: June 12, 2007Assignee: Sony CorporationInventors: Chikara Ute, Kiyoshi Kawakubo, Takeshi Sano, Yukio Matsumoto, Akira Ishihara, Noboru Fujita, Yutaka Ogasawara, Hiroaki Masuda, Daisuke Matsuo

Patent number: 5315847Abstract: A washing machine comprises a washing/dehydrating tank, a water storage tank in which the washing/dehydrating tank is disposed, and a sensor for detecting an electric conductivity of washing water in the washing/dehydrating tank and the water storage tank. The sensor is provided with a pair of electrodes to take into account a variation of an electric resistance of the washing water therebetween, which is representative of the electric conductivity of the washing water, thereby controlling a washing operation of the washing machine. The sensor has a CR oscillation circuit including a resistance which represents the electric conductivity of the water between the electrodes. A variation of the electric conductivity of the washing water is converted into an oscillation frequency variation of the oscillation circuit, and the operation of the washing machine is controlled on the basis of the thus varying oscillation frequency.Type: GrantFiled: March 30, 1992Date of Patent: May 31, 1994Assignee: Hitachi, Ltd.Inventors: Yoshiaki Takeda, Katuyosi Miwano, Noboru Fujita
