| 20080301720 | Disc Drive - There is provided a disc drive by which the fluid loss of a disc is reduced and the electric power consumption of a spindle motor can be decreased. In the disc drive according to the present invention, a rotation load reducing member is provided between a top cover and the disc. The rotation load reducing member is movably supported by a clearance adjustment member. While the disc is rotating, the rotation load reducing member is moved in the direction approaching the disc. Thereby, the thickness of an air layer on the upper surface of the disc is decreased. | 12-04-2008 |
| 20090265725 | OPTICAL DISC APPARATUS - An optical disc apparatus capable of being thinned and lightened while ensuring a mechanical strength and a stiffness, and also capable of restraining sticking of an FPC and reducing the sliding resistance of the FPC, comprises a frame, a motor arranged in the frame, for rotating an optical disc loaded in the optical disc apparatus, an optical pickup arranged in the frame so as to be movable in a radial direction of the optical disc, for carrying out at least one of recording and reproduction of signals onto and from a data recording surface of the loaded optical disc, an FPC arranged in the frame, for connecting between the optical pickup and a circuit board, and a unit cover for covering the frame on the mounting surface side of the optical disc, the unit cover having a first zone including an area made into contact with the FPC, and second zones projected toward the mounting surface side of the optical disc from the first zone and located on opposite sides of the first zone so as to interpose a part of the area made into contact with the FPC. | 10-22-2009 |
| 20090288107 | OPTICAL DISC APPARATUS - An optical disc apparatus including first to fourth disc guides. At the end of disc loading, the first one, in a fixed position, contacts a peripheral side face of the optical disc at a first point thereon to support the disc; the second one has a plane opposite to the peripheral side face which contacts the peripheral side face of the optical disc at a second point to support the disc while restrained from moving away from the side face; the third one contacts the peripheral side face of the optical disc at a third point to support the disc while biased by a spring; and the fourth one contacts the side face at a fourth point while biased by a spring to support the disc, and is restrained from moving against the resilience of the spring. The disc, supported by those disc guides, is chucked by a clamper. | 11-19-2009 |
| 20090293077 | OPTICAL DISK DEVICE - An optical disk device in which the thickness of the device is not increased, and interference between the bottom surface of an optical pickup unit (OPU) and a bottom case of the device is prevented upon emergency ejection of an optical disk without moving the optical pickup unit to an outermost peripheral position of the disk in the event of abnormality such as power shutdown during an operation in the optical disk device. A support mechanism having a coil spring is provided at shaft-holders in three of four positions of a guide main shaft and a guide sub shaft to support an OPU, to perform skew adjustment. In another position, a support mechanism having a plate spring is provided such that, upon emergency ejection, the interference between the bottom surface of the OPU and the bottom case is mitigated. | 11-26-2009 |
| 20100058369 | OPTICAL DISK APPARATUS - The present invention provides an optical disk apparatus which allows for accurate centering of an optical disk regardless of its placed attitude and in which reliability of chucking operation has been improved, and the apparatus includes a first disk guide | 03-04-2010 |
| 20100083291 | OPTICAL DISC APPARATUS - The invention makes it possible to carry out an emergency eject motion without attaching and detaching teeth between gears in a transmission system of a driving force of a loading motor, in an optical disc apparatus. At least one of gear units in a gear train constructing a transmission system between a loading motor and a disc moving mechanism is structured such that a driving gear is coupled in an inner diameter side of a large diameter driven gear in such a manner as to be movable in an axial direction and be rotatable integrally with the driven gear, and the driving gear moves and displaces in an axial direction with respect to the driven gear, thereby being canceled the coupling with the driven gear while keeping an engagement with a gear in the next stage, canceling the coupling by an external force by a manual operation so as to set the transmission system to a disconnection state at a time of an emergency eject, making the disc moving mechanism carry out a disc discharge motion by the external force, and discharging an optical disc out of the apparatus. | 04-01-2010 |

| 20110059145 | TOPICAL COMPOSITION FOR EXTERNAL USE AND PROCESS FOR PRODUCING THE SAME - A topical composition for external use comprising: a ceramide analogue-containing particle having a particle diameter of 0.001 μm to 0.2 μm; and a water-soluble polymer. It is preferable that, further, an oil component different from the ceramide analogue is contained in an amount of 20 parts by mass or less relative to 1 part by mass of the ceramide analogue-containing particle, and the ceramide analogue-containing particle is present in the oil component. | 03-10-2011 |
| 20110182999 | CERAMIDE DISPERSION AND METHOD FOR PRODUCING SAME - The present invention provides a ceramide dispersion which includes (1) ceramide-containing particles which contains a ceramide, which are dispersed in an aqueous phase as an oil-phase component, and which have a volume average particle diameter from 1 nm to 100 nm; and (2) a fatty acid component which is at least one of a fatty acid having a melting temperature not higher than 30° C. or a fatty acid salt; the amount of nonionic surfactant being 0 or not more than 0.1 times the total mass of the ceramide; the amount of an ionic surfactant other than the fatty acid component being 0 or less than 0.05 times the total mass of the ceramide; and the pH being from 6 to 8. | 07-28-2011 |
| 20110224310 | CERAMIDE DISPERSION AND METHOD FOR PRODUCING SAME - The present invention provides a ceramide dispersion which includes (1) ceramide-containing particles which contain a ceramide, which are dispersed in an aqueous phase as an oil-phase component and which have a volume average particle diameter from 1 nm to 100 nm, (2) a fatty acid component which is at least one of a fatty acid and a fatty acid salt, (3) a polyhydric alcohol in an amount from 5 to 20 times larger than an amount of the ceramide and (4) a polysaccharide fatty acid ester; and in which the pH is from 6 to 8. | 09-15-2011 |
