| 20100022918 | SENSING SYSTEM EMPLOYING MEDICAL MANIPULATOR AND PRESSING FORCE MEASURING DEVICE AND ITS PROGRAM - Sensing of the pressing force of a balloon against internal body tissues is made possible using the balloon inserted into a gap in the body and pressing the internal body tissues around that gap without inserting a sensor, or the like, separately into the gap. A sensing system comprises an surgical assist manipulator provided to be able to travel by a reaction produced while it pressure-displaces the internal body tissues, a pressure sensor for measuring the pressure of fluid used to operate the surgical assist manipulator, and a pressing force measuring device for determining a pressing force applied to the internal body tissues by the surgical assist manipulator based on the measurement by the pressure sensor. The surgical assist manipulator includes a balloon which can be expanded/contracted by fluid being supplied internally, and the pressing force measuring device determines a function employing the internal pressure when the balloon is pressed as a parameter based on the measurement of fluid amount supplied to the balloon, and determines the pressing force by substituting the internal pressure at pressing measured by the pressure sensor into that function. | 01-28-2010 |

| 20110013694 | VIDEO QUALITY OBJECTIVE ASSESSMENT METHOD, VIDEO QUALITY OBJECTIVE ASSESSMENT APPARATUS, AND PROGRAM - A bit string of a video encoded using motion-compensated inter-frame prediction and DCT and, more particularly, H.264 is received. A quantization parameter included in the received bit string is extracted, and its statistic is calculated. The subjective quality of the video is estimated based on the minimum value of the quantization parameter. | 01-20-2011 |
| 20110026585 | VIDEO QUALITY OBJECTIVE ASSESSMENT METHOD, VIDEO QUALITY OBJECTIVE ASSESSMENT APPARATUS, AND PROGRAM - A motion vector or DCT coefficient which exists in the bit string of an encoded video and serves as a parameter representing the difference between scenes, or encoding control information or pixel information obtained by partially decoding the bit string of the encoded video is used for video quality objective assessment. It is consequently possible to save the amount of pixel information decoding processing that requires an enormous amount of calculation as compared to video quality objective assessment apparatus using pixel information obtained by decoding the bit string of an entire video. This allows to perform video quality objective assessment in a short time using an inexpensive computer. | 02-03-2011 |

| 20090274477 | FIXING DEVICE AND IMAGE FORMING APPARATUS CAPABLE OF SUPPRESSING VARIATION IN IMAGE DENSITY - A fixing device includes a rotatable first nip formation member, a rotatable second nip formation member, a first heater, a second heater, and a controller. The second nip formation member is provided under the first nip formation member to contact the first nip formation member to form a fixing nip portion between the first nip formation member and the second nip formation member. The first heater heats the first nip formation member. The second heater heats the second nip formation member. The controller supplies a portion of power to the second heater and the remainder of power to the first heater when a plurality of sheets having a sheet weight not greater than about 100 g/m | 11-05-2009 |
| 20090274494 | IMAGE FORMING APPARATUS CAPABLE OF STABLY APPLYING OIL FOR FIXING - An image forming apparatus includes an oil input device and a fixing device including a fixing member, a pressing member, and an oil applier. In the oil applier, an oil application member applies oil supplied from an oil supply mechanism to one of the fixing member and the pressing member. In the oil supply mechanism, an oil supply member provided adjacent to an oil storage member supplies oil sent from the oil storage member to the oil application member. When the fixing device is reattached to the image forming apparatus after the fixing device is detached from the image forming apparatus, oil sent from the oil input device through an oil inlet overflows the oil storage member, and is supplied to one of the oil supply member and the oil application member provided adjacent to the oil storage member before an image forming operation starts. | 11-05-2009 |
| 20090274495 | FIXING DEVICE AND IMAGE FORMING APPARATUS CAPABLE OF ADJUSTING AMOUNT OF OIL APPLIED FOR FIXING - A fixing device includes a rotatable fixing member, a pressing member, a motor, and an oil applier. The pressing member contacts the fixing member. The oil applier includes an application roller and an oil supply mechanism. The application roller applies oil to one of the fixing member and the pressing member. The oil supply mechanism supplies oil to the application roller. The motor is provided independent of other drivers, and supplies a driving force to the application roller to rotate the application roller at an arbitrary speed. | 11-05-2009 |
| 20090274496 | Fixing device, image forming apparatus, and image fixing method capable of stably applying oil for fixing without adhering oil to sheet - In a fixing device, a controller switches a pressing member between a pressure application state to contact the pressing member against a fixing member and a pressure release state to separate the pressing member from the fixing member. The controller starts rotation of the pressing member before the pressing member contacts the fixing member in the pressure application state, when the pressing member switches from the pressure release state to the pressure application state. An oil applier includes an oil pan and an oil regulating member. The oil pan is provided under the pressing member to contain oil in which the pressing member is dipped. The oil regulating member is provided downstream from the oil pan in a direction of rotation of the pressing member to contact the pressing member to regulate an amount of oil adhering to the pressing member. | 11-05-2009 |
| 20090274497 | Fixing device and image forming apparatus capable of effectively circulating and applying oil for fixing - A fixing device includes a rotatable first nip formation member, a rotatable second nip formation member, and an oil applier. The second nip formation member is provided under the first nip formation member to contact the first nip formation member. The oil applier includes an oil pan, an oil receiver, and an oil filter. The oil pan is provided under the second nip formation member to contain oil in which the second nip formation member is dipped. The oil receiver holds the oil pan. The oil filter is provided between the oil pan and the oil receiver to filter oil overflowing the oil pan. | 11-05-2009 |
| 20090274498 | FIXING DEVICE AND IMAGE FORMING APPARATUS WITH IMPROVED MECHANISM FOR STABLY APPLYING OIL FOR FIXING - A fixing device includes a fixing member, a pressing member, and an oil applier. In the oil applier, an oil application member applies oil supplied from an oil supply mechanism to one of the fixing member and the pressing member. In the oil supply mechanism, an oil storage member is provided above and adjacent to one of an oil supply member and the oil application member to supply oil overflowing the oil storage member, when oil is put into the oil storage member through an oil inlet, to one of the oil supply member and the oil application member. The oil supply member provided adjacent to the oil storage member supplies oil sent from the oil storage member to the oil application member. | 11-05-2009 |
