20080278074 | Gas Discharge Display Panel - Provided is a gas discharge display panel that exhibits a favorable display performance by maintaining a wall charge retaining power, controlling discharge delay within a range adequate for optimal image display, and reducing the discharge starting voltage at comparatively low cost. Also provided is a PDP that exhibits more reliability with enhanced display quality by further improving the secondary electron emission factor γ compared to conventional cases and lowering the discharge starting voltage to widen the driving margin. Further provided is a manufacturing method of a gas discharge display panel, by which the manufacturing cost lowers by reduction of the exhaustion time in the sealing exhaustion process, and by which the driving circuit cost is reduced. In a gas discharge display panel of the present invention, a protective layer ( | 11-13-2008 |
20090059761 | OPTICAL DISC APPARATUS AND OPTICAL PICKUP - An optical disc apparatus according to the present invention includes: an optical pickup including an optical system that converges a light beam on an optical disc and a photodetector that detects light reflected from the optical disc; and a fingerprint detector for detecting, based on the output of the photodetector, multiple fingerprint dots on the surface of the optical disc. The fingerprint detector confirms the presence of a fingerprint on the optical disc on sensing the output of the photodetector change according to the pattern of the fingerprint dots. | 03-05-2009 |

20110292779 | METHOD FOR IDENTIFYING GROUP OF MULTILAYER DISC, AND OPTICAL DISC DEVICE - The present invention provides a method for determining what group a given multilayer optical disc belongs to. The disc is one of a number of multilayer optical discs, which are designed so that information stored is retrievable from any of the discs by irradiating the disc with a light beam having the same wavelength and which have been classified into multiple groups. According to this method, performed first is Step (A) of measuring either a distance from a first one of multiple information layers of the given multilayer optical disc to a second one thereof, which is located adjacent to the first information layer, or a distance from the first information layer to the surface of the optical disc. Next, Step (B) of determining, by the distance measured, what group the given multilayer optical disc belongs to is performed. | 12-01-2011 |
