| 20080292343 | Image forming apparatus - In an early-middle stage of a photosensitive drum life cycle, an image forming apparatus uses only a second semiconductor laser having an oscillation wavelength 660 nm to perform writing of an electrostatic latent image on a photosensitive drum surface. In a middle-late stage of the photosensitive drum life cycle, the image forming apparatus starts using a first semiconductor laser having an oscillation wavelength of 440 nm in addition to the second semiconductor laser to perform writing of an electrostatic latent image on the photosensitive drum surface with a combined exposure spot formed at the same position. An exposure control unit gradually increases an output rate of the first semiconductor laser according to an increase in total output of the first and second semiconductor lasers. | 11-27-2008 |
| 20090190946 | IMAGE FORMING APPARATUS - In an image forming apparatus, a control portion forms a restoring toner image (restoring toner band) at a position, in which the refreshing toner image overlaps with a control image with respect to a longitudinal direction of a secondary transfer roller, during post-rotation after image formation in an image forming job is completed. The restoring toner band is formed in a length corresponding to 3 full circumferences of the secondary transfer roller for one-sheet image forming job, 2 full circumferences of the secondary transfer roller for 5-sheet image forming job, and one full circumference of the secondary transfer roller for 10-sheet image forming is job. In the case of an image forming job on 50 sheets or more, a lowering in cleaning performance of a secondary transfer member cleaning device for the secondary transfer roller is not caused to occur, so that the restoring toner band is not formed. | 07-30-2009 |
| 20090190950 | IMAGE FORMING APPARATUS - In an image forming apparatus, when backside contamination of a recording material occurs, a control portion carries out control so that a plurality of restoring toner bands having a length L | 07-30-2009 |
| 20090190951 | IMAGE FORMING APPARATUS - When a switch displayed on an operation panel is operated, a control portion starts aging control in which image formation is stopped and yellow toner is applied onto an intermediary transfer belt and a secondary transfer roller. A toner band is formed, on full circumference of the intermediary transfer belt at a position in which toner images for control are formed, with a width correspondingly to widths of the toner images for control. | 07-30-2009 |

| 20090092026 | OPTICAL DISC DEVICE AND CONTROL CIRCUIT FOR OPTICAL DISC DEVICE - To prevent the focal point of a light beam from entering an unrecorded area, where no data has been written yet, when data is being read continuously from multiple storage layers. | 04-09-2009 |
| 20100020650 | RECORDING APPARATUS - Even when a data area and a spare area are procured on a recording medium in advance, performs a replacement process for the replacement area only under specific cases where recording for the data area is impossible, so that the recording areas can be efficiently utilized. | 01-28-2010 |
| 20110205877 | OPTICAL DISC DRIVE AND METHOD FOR READING DATA FROM OPTICAL DISC - An optical disc drive according to the present invention is designed to read data from a multilayer optical disc | 08-25-2011 |

| 20100315066 | CURRENT SENSOR - A current sensor for measuring a current supplied to a conductor includes a case which accommodates an electrical parts therein, and a cover attached to the case. A groove part is provided on an outer surface of at least one of the case and the cover to allow the conductor to pass through the groove part. When the cover is attached to the case, the conductor arranged on the groove part is sandwiched between the case and the cover. A width of the groove part becomes narrower toward an interior side thereof. | 12-16-2010 |

| 20110135456 | GAS TURBINE PLANT - Provided is a gas turbine plant that enables active clearance control for ensuring tip clearance of first-stage turbine rotor blades required during start-up and for achieving the minimum tip clearance during load operation. In a gas turbine plant including a cooler in an air system used for cooling second-stage turbine stator blades, a first-stage segmented ring and a second-stage segmented ring that oppose tips of first-stage turbine rotor blades and second-stage turbine rotor blades are supported by the same blade ring member, and a cooling-air for the second-stage turbine stator blades forms a cooling air flow cooling the blade ring, to control thermal expansion of the blade ring and to control the clearance with respect to the tips. | 06-09-2011 |

| 20110222843 | FOCAL PLANE SHUTTER FOR DIGITAL CAMERAS - When a hold member rotates on a shaft counterclockwise in the set operation, pressing parts of a pressing member which is fitted on top end of the hold member press pressed parts of iron piece members to rotate a lock-releasing member for a first blade and a lock-releasing member for a rear blade so that the iron piece members are made to come into contact with iron-core members of electromagnets, while an engagement pin presses an arm of a connection spring to rotate a restraining member clockwise so that a restraining part of the restraining member moves into the trajectory of the movement of a restrained part of the lock-releasing member for the rear blade. When the coils of the electromagnets are not electrified and the hold member rotates clockwise, the lock-releasing member for the front blade presses a front blade locking member to make it possible to perform an open operation of the front blade, while the lock-releasing member for the rear blade cannot press a rear blade locking member because the lock-releasing member for the rear blade is restrained by the restraining member. As a result, an exposure aperture is fully opened, and it becomes possible to perform observation with electronic finder. | 09-15-2011 |
