Patent number: 9556098Abstract: With respect to reduced coenzyme Q10, there has been no report about the presence of crystal polymorphism, and it has been considered that a conventionally obtained crystal form is only one form. The present invention relates to a reduced coenzyme Q10 crystal having an endothermic peak indicating melting at 54±2° C. during temperature rise at a rate of 5° C./min by differential scanning calorimetry (DSC), and/or to a reduced coenzyme Q10 crystal showing characteristic peaks at diffraction angles (2?±0.2°) of 11.5°, 18.2°, 19.3°, 22.3°, 23.0° and 33.3° by powder X-ray (Cu—K?) diffraction. The crystal form is a novel reduced coenzyme Q10 crystal which has a higher melting point and a lower solubility in a solvent, and is more excellent in stability than the conventionally known reduced coenzyme Q10 crystal.Type: GrantFiled: June 14, 2016Date of Patent: January 31, 2017Assignee: KANEKA CORPORATIONInventors: Hideo Kawachi, Shiro Kitamura, Yasuyoshi Ueda

Patent number: 8634287Abstract: An information signal area on an information signal recording surface is provided as pits on a mirror in accordance with modulated information data, and is covered with a metal alloy reflective film. Sections that do not include pits corresponding to the information data are provided in the information signal area, and portions of the metal alloy reflective film on the sections are formed as perforated marks corresponding to the information data. In this case, the reproduction signal amplification level of a prepit signal and the reproduction signal amplitude level of a perforated mark signal can be obtained as substantially equal values by adjusting the depth and width of pits and/or adjusting the width and length of perforated marks. Hence, waveform distortion due to a waveform equalization circuit and variations in binary signals due to displacement of the slice level are reduced so that signals can be stably and reliably detected with the same reading apparatus.Type: GrantFiled: December 8, 2008Date of Patent: January 21, 2014Assignee: Sony CorporationInventors: Tetsuhiro Sakamoto, Jun Nakano, Takayuki Asahina, Etsuo Shibasaki, Hideo Kawachi

Patent number: 5375106Abstract: In a reproducing system, a reproducing start position of recording information is set in a first reproducing device reproducible in a second reproducing device. The reproducing start position set in the first reproducing device is stored in a detachable external storage medium. The external storage medium is detached from the first reproducing device, attached to a second reproducing device, and the reproducing start position stored in the external storage medium is read into the second reproducing device. Thus the reproducing start position set by the first reproducing device will be reproduced in the second reproducing device to control a location of selection, such as musical numbers.Type: GrantFiled: December 4, 1992Date of Patent: December 20, 1994Assignee: Sony CorporationInventors: Hideo Kawachi, Koji Ishiwata, Toshiharu Kondo

Patent number: 5301176Abstract: A disk player for use of playback of both of the single body of a digital optical disk and another digital optical disk encased in a cartridge by a single player. The disk player comprises a disk tray which is mounted on a main chassis and adapted to make its reciprocating movement in the fore-and-aft direction of the player to carry the single body of the disk to a predetermined position in the player. A cartridge carrier is mounted on a sub-chassis connected to and located above the main chassis and makes its reciprocating movement in the fore-and-aft direction to carry the cartridge encasing therein the disk to another predetermined position in the player. A mechanical chassis is tiltably connected to and located below the main chassis and movable upwardly and downwardly. A turntable is rotatably mounted on the mechanical chassis and driven by a motor supported to the mechanical chassis. Either one of the disks carried at the predetermined position is mounted on the turntable to be played back.Type: GrantFiled: June 8, 1992Date of Patent: April 5, 1994Assignee: Sony CorporationInventors: Hideo Kawachi, Katsuichi Sakurai, Toshiyuki Arai

Patent number: 5299185Abstract: A disc player is shown which can play both a naked disc and a disc encased in a cartridge. A disc tray is movable on a single horizontal way to take at least first, second and third positions which are respectively the position for receiving or ejecting the naked disc, the position for practically playing the naked disc and the position which is distant from the second and third positions. When playing of the cartridge is intended, the disc tray is moved to the third position to permit the cartridge to take a loaded position at which the cartridge is practically played.Type: GrantFiled: July 28, 1992Date of Patent: March 29, 1994Assignee: Sony CorporationInventors: Katsuichi Sakurai, Hideo Kawachi, Toshiyuki Arai

Patent number: 4530073Abstract: In an apparatus for reproducing digitized signals recorded in successive, substantially circular tracks on a rotated disc by means of a pickup of the optical type which, in a normal scanning state, scans the tracks in succession; a first or prepare-to-play command signal causes the pickup to reproduce the digitized signals for a predetermined interval corresponding to more than one of the tracks on the disc starting from a desired position on such one track and the digitized signals reproduced in that predetermined interval are stored, desirably in a random access memory (RAM), whereupon a standby state of the pickup is established in which the pickup traces a closed loop on the rotated disc within a range corresponding to the previously mentioned predetermined interval.Type: GrantFiled: August 17, 1982Date of Patent: July 16, 1985Assignee: Sony CorporationInventors: Teruaki Higashihara, Tadao Yoshida, Hideo Kawachi, Chiaki Nonaka
