| 20110019658 | COMMUNICATION APPARATUS, DISTORTION-COMPENSATING CIRCUIT, AND DISTORTION COMPENSATION METHOD - A transmission circuit sends a transmission signal from a signal-processing unit to a port. A reception circuit sends a received signal from a port to the signal-processing unit. A waveform monitor, by monitoring the waveform of the transmission signal that is sent to the port from the transmission circuit, generates a feedback signal. A switch unit connects the feedback signal from the waveform monitor to the reception circuit at transmission timing. The signal-processing unit compares the transmission signal with the feedback signal of the transmission signal. | 01-27-2011 |

| 20110192093 | METHOD FOR PRODUCING SINTERED CUBIC BORON NITRIDE COMPACT - A method for producing a highly uniform and highly dense sintered cubic boron nitride compact having high hardness by sintering at a milder condition without a binder, is provided. The method includes deflocculating secondary particles in cubic boron nitride starting powders by dispersing the starting powders in a solution of a deflocculant; molding the green compact after removing the solution of the deflocculant from the starting powders; and then sintering the green compact in the presence of a supercritical fluid source in a supercritical state by pressing and heating the green compact together with the supercritical fluid source. The supercritical fluid source can be one or more selected from a group consisted of polyvinylidene chloride, polyvinyl chloride, polyethylene, polypropylene, polystyrene, a polyester and an ABS resin. In the sintering, the pressure is 5 GPa or higher, and the temperature is 1400° C. or higher. According to the method, a highly uniform and highly dense sintered cubic boron nitride sintered compact having high hardness, can be obtained. | 08-11-2011 |

| 20080291240 | IMAGE FORMING APPARATUS - An image forming apparatus is disclosed. The image forming apparatus executes operations of idle ink ejection in which ink droplets not contributing to forming an image on a recording medium are ejected. When the operations of the idle ink ejection are executed before staring to print an image on a recording medium, the ink droplets are ejected into a cap member; in a case where the operations of the idle ink ejection are executed when a first predetermined period has passed after the last ejection of the ink droplets from the recording head, the ink droplets are ejected into an idle ink droplet receiving section; and in a case where the operations of the idle ink ejection are executed when a second predetermined period longer than the first predetermined period has passed as one of cleaning operations of the recording head, the ink droplets are ejected into the cap member. | 11-27-2008 |
| 20110050816 | IMAGE FORMING APPARATUS - An image forming apparatus is disclosed that includes the pressure adjusting valve including a movable member movably disposed in the pressure adjusting valve, a first throttling part; and a second throttling part, wherein the second throttling part is formed as a gap between an internal wall of the frame of the pressure adjusting valve and the movable member, an internal fluid resistance of the pressure adjusting valve varies in response to the flow rate of the liquid, and when the liquid is discharged from the nozzle, the liquid is fed from the liquid tank to the recording head by the liquid feeding unit in a state where the recording head is in fluid communication with the liquid tank via the pressure adjusting valve. | 03-03-2011 |
