20110050435	PROJECTION DISPLAY DEVICE - A projection display device includes: a dustproof filter that removes dust and a foreign material from drawn air; an air guide path that guides, to a liquid crystal panel, the cooling air blown by a suction fan; an air velocity detector that is arranged in the air guide path and detects the velocity of the cooling air that flows in the air guide path; and a CPU that determines, on the basis of the value detected by the air velocity detector, whether or not the dustproof filter is clogged. The air velocity detector detects the velocity of the cooling air by measuring the temperature of the air in the vicinity of the heat generating element that will be increased due to heat transfer generated by the heat generating element. This configuration improves accuracy in determining whether or not the dustproof filter is clogged.	03-03-2011

20080298194	Optical disc apparatus and data recording method thereof - In order to ensure recording quality while suppressing the adverse effects due to performance variations among apparatuses and disc radial positions on an optical disc, an optical disc apparatus according to the present invention performs, at the time of data recording, the steps of: acquiring a jitter value and β value from a reproduced signal based on laser light reflected from the optical disc in relation to a disc radial position; learning a β value when the acquired jitter value is a minimum as a target β value; and, if a jitter value acquired thereafter is larger than the minimum jitter value by a preset reference value or above, correcting recording power based on the magnitude relation and the difference between the β value associated with the acquired jitter value and the target β value or performing trial record processing.	12-04-2008
20080298204	Optical disc drive apparatus - An optical disc drive apparatus, for recording/reproducing upon/from an optical disc medium having a plural number of recording layers, comprises a recording/reproducing element, which is configured to irradiate a laser upon the optical disc medium, to as to conduct recording/reproducing thereon/from, wherein recording is conducted within a region of an arbitrary range on the optical disc medium by means of the recording/reproducing element, and the region is used for moving an optical spot of the laser irradiated from the recording/reproducing element when recording/reproducing data thereon/from.	12-04-2008
20090052306	Semiconductor Laser Generator and Method of Controlling the Same, and Optical Disk Device - The present invention provides a laser generator that allows recording quality to be improved, a method of controlling the laser generator, and an optical disk device. In a laser emitting device including a semiconductor laser diode emitting laser and a semiconductor laser diode driving section supplying a driving pulse to the semiconductor laser diode to drive the semiconductor laser so as to blink on the basis of the driving pulse, an impedance between the semiconductor laser diode and the semiconductor laser diode driving section is controlled to an appropriate condition.	02-26-2009
20090080301	Method of Recording Information On and Reproducing Information From Optical Disk and Apparatus for the Same - There is provided an information recording and reproducing method and an apparatus for the same capable of optimizing the shift adjustment of a recording pulse recorded in an optical disk even at the time of recording information on the optical disk at a high speed. The shift adjustment value of the recording pulse optimized at a low speed recording on an optical disk is multiplied by a constant value to be taken as the optimum shift conditions of the recording pulse at the high speed recording.	03-26-2009
