| 20090296549 | Optical Disk Device - The precision of a direction detection signal DIR is judged from the duty ratio of the direction detection signal DIR, and the direction detection signal DIR which is used for track search control or tracking pull-in control is judged as valid or invalid according to the precision, thereby to improve the precision of the track search control or the tracking pull-in control. Therefore, even when the direction detection is not performed accurately due to a difference in the reflected light quantity on the optical disk, a defect on the optical disk, a delay in the track cross speed during search, or a delay in the detection circuit, the track search control and the tracking pull-in control can be performed with stability. | 12-03-2009 |
| 20110085427 | FOCUS POSITION CONTROL APPARATUS, OPTICAL DISC APPARATUS USING THE SAME, AND FOCUS POSITION CONTROL METHOD - A focus position control apparatus includes a memory unit configured to sequentially store a control signal for controlling a focus position of an optical beam to a desired position in synchronization with a clock signal at an associated one of clock addresses whose one round is completed as an optical disc rotates once, a memory data output unit configured to sequentially read the memory data stored in the memory unit in synchronization with the clock signal, a phase correction unit configured to correct, when the memory data output unit reads the memory data from the memory unit, a phase shift between a clock address for reading and a clock address for storing, and an adding unit configured to add an output signal of the memory data output unit to the control signal. | 04-14-2011 |

| 20090136273 | Fixing device and image forming apparatus - A fixing device and an image forming apparatus including the fixing device are supplied capable of preventing life of roller from shortening due to big shearing warp. | 05-28-2009 |
| 20090136274 | Fixing device and image forming apparatus - A fixing device fixes a recording medium with a toner image transferred thereon. The fixing device includes an endless belt heated with a heating member; a first pressing member contacting with the endless belt and extending the endless belt together with the heating member; a second pressing member for pressing the endless belt and sandwiching the endless belt together with the first pressing member; and a high thermal conductive member contacting with an inner surface of the endless belt and disposed along a direction crossing a direction that the endless belt moves. | 05-28-2009 |
| 20090162115 | FIXING DEVICE AND IMAGE FORMING APPARATUS - A fixing device includes a heat member, a belt member, a belt support member, a first rotation member, a second rotation member, and a separation contact mechanism. The belt member is heated by the heat member. The belt support member operably supports the belt member. The first rotation member tightly stretches the belt member with the belt support member. The second rotation member is disposed opposite to the first rotation member through the belt member. The separation contact mechanism makes the heat member to contact the belt member when the first rotation member rotates, and makes the heat member separate from the belt member when the first rotation member halts. | 06-25-2009 |
| 20090324266 | FIXING DEVICE AND IMAGE FORMING DEVICE - A fixing device comprise an endless fixing belt; a first heater that heats a first predetermined section of the fixing belt, a second heater that heats a second predetermined section of the fixing belt, a switch that determines whether or not the second predetermined section of the fixing belt is heated by the second heater, a controller controls a switching operation of the switch according to a size of a medium on which an image is fixed by the fixing belt, and a temperature controller that reduces a heating temperature of the first heater when the second predetermined section of the fixing belt is heated by the second heater. | 12-31-2009 |
| 20110003202 | BINDER COMPOSITION FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY ELECTRODE AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY - Disclosed is a binder composition for a nonaqueous electrolyte secondary battery electrode including an antioxidizing agent, able to inhibit the thickening of an electrode slurry. The binder composition enables to form electrode slurry without making the antioxidizing agent adhere to the insides of fine pores of electrode active materials after coating and drying. The binder composition for a nonaqueous electrolyte secondary battery electrode contains a binder and an emulsified antioxidizing agent, and particularly, it is preferable that the binder is an aqueous binder including a diene-based polymer and that the antioxidizing agent is a polymeric phenol compound. | 01-06-2011 |
