| 20090080037 | Condenser Lens and Optical Scanning Device - A condenser lens including a plurality of divided lens faces which is formed in a Fresnel lens shape with grooves on a light incidence face and a light emitting face, where the divided lens faces includes a diffraction lens face on which a plurality of steps is formed. | 03-26-2009 |
| 20090213447 | LIGHT BEAM SCANNING DEVICE - A light beam scanning device may include a light source device, and an optical deflection mechanism for scanning a light beam which is emitted from the light source device over a prescribed angular range by an optical deflection element. The light source device may be provided with a light emitting source and a condenser lens for guiding the light beam emitted from the light emitting source as a converged light beam which is focused on the optical deflection element or its vicinity in at least one of a first direction and a second direction which are perpendicular to an optical axis direction. The light beam scanning device may further include a divergence angle modification lens for varying a divergence angle of an emitted light beam from the optical deflection element in at least a direction perpendicular to a scanning direction by the optical deflection element. | 08-27-2009 |
| 20100035524 | METHOD OF PRODUCING OPTICAL ELEMENT, AND OPTICAL ELEMENT - While having a milling cutter, equipped with a rotary shaft and a blade portion projecting in the direction intersecting with the axial line direction of the rotary shaft, rotated about the axial line of said rotary shaft, the milling cutter and the base material for forming an optical device are relatively moved in the cutting-in direction and the feed direction to form machining faces that constitute the device face. At the boundary part of the machining faces, the rotary shaft is directed in the direction orthogonal to the boundary part to cut the lower machining face of two adjacent machining faces. | 02-11-2010 |
| 20100045982 | PARTICLE COUNTER AND PARTICLE COUNTING DEVICE HAVING PARTICLE COUNTER, AND PARTICLE COUNTING SYSTEM AND ITS USE METHOD - A particle counting device | 02-25-2010 |

| 20080225666 | RECORDING MEDIUM PLAYBACK DEVICE AND RECORDING MEDIUM PLAYBACK METHOD - There is provided a recording medium playback device that includes a first binarization portion that binarizes, by a PRML method, a signal that is read from a recording medium, a second binarization portion that binarizes the signal based on a magnitude relationship to a specified threshold value, a first frame synchronization signal detection portion that detects a synchronization pattern in a first binarized data string that is produced by the first binarization portion, and a second frame synchronization signal detection portion that detects a synchronization pattern in a second binarized data string that is produced by the second binarization portion. If the synchronization pattern is not detected by the first frame synchronization signal detection portion, a signal that is derived from the synchronization pattern that is detected by the second frame synchronization signal detection portion is used as the frame synchronization signal. | 09-18-2008 |
| 20090065182 | COOLING DEVICE - There is provided a cooling device which includes a plurality of cooling modules | 03-12-2009 |
| 20090080155 | ELECTRIC POWER CONVERSION APPARATUS - In a conventional cooling device, a heat pipe or a circulation-type liquid cooler provided with a pump is used and therefore, a large space is needed for the cooling device. There is provided a cooling device which includes a plurality of cooling modules | 03-26-2009 |
| 20110116893 | CONNECTION STRUCTURE FOR SHEET-METAL PARTS AND IMAGE FORMING APPARATUS - An object of the present invention is to provide a connection structure for sheet-metal parts that permits two sheet-metal parts to be screwed to each other with good conductivity by a simple process in a simple structure, and an image forming apparatus provided with the connection structure. | 05-19-2011 |
