20110042730 | Semiconductor device manufacturing method and semiconductor device - A formation method of an element isolation film according to which a high-voltage transistor with an excellent characteristic can be formed is provided. On a substrate, a gate oxide film is previously formed. A CMP stopper film is formed thereon, and thereafter, a gate oxide film and a CMP stopper film are etched. The semiconductor substrate is etched to form a trench. Further, before the trench is filled with a field insulating film, an liner insulating film is formed at a trench interior wall, and a concave portion at the side surface of the gate oxide film under the CMP stopper film is filled with the liner insulating film. In this manner, formation of void in the element isolation film laterally positioned with respect to the gate oxide film can be prevented. | 02-24-2011 |

20130064584 | FUSER DEVICE AND IMAGE FORMING APPARATUS PROVIDED WITH SAME - A fuser device includes a first motor for rotatably driving one of a heating member and a pressure-applying member, a second motor rotating either in a forward direction or a reverse direction in order to switch a pressure-application-switching mechanism between an applied-pressure state and a released-pressure state, a first detector for detecting whether the first motor is rotating, and a second detector for detecting the forward-direction or reverse-direction rotation of the second motor. The first detector has a first sensor for detecting the rotation of the first detector plate caused to rotate by the first motor. The second detector has a second sensor for detecting changes in the rotational state of the second detector plate caused to rotate in the forward and reverse directions by the second motor. A single sensor constitutes the first sensor and the second sensor. | 03-14-2013 |
20140153956 | CLEANING DEVICE, INTERMEDIATE TRANSFER UNIT AND IMAGE FORMING APPARATUS - A cleaning device has housing, cleaning member, pair of bearing portions, toner receiving seal, and end seal. The housing is formed with opening facing, and waste toner retaining portion. The cleaning member is rotatably borne by the pair of bearing portions at both ends of rotation axis. The toner receiving seal is disposed facing to entire area in the longitudinal direction of the cleaning member, and extends to be laid across each end portion of the cleaning member and outer periphery of the bearing portion. The bearing portion has the same outer diameter in contact portion where the toner receiving seal contacts, as outer diameter of the cleaning member. The end seal is disposed, in gap between the housing and each of the bearing portions, facing to the contact portion with the toner receiving seal interposed therebetween, and prevents leakage of waste toner from both end portions of the housing. | 06-05-2014 |
20140153957 | CLEANING DEVICE, INTERMEDIATE TRANSFER UNIT INCLUDING THE SAME, AND IMAGE FORMING APPARATUS INCLUDING THE SAME - A cleaning device includes a housing, a cleaning member, a contact member, a torque limiter, and an urging member. The housing has an opening that opposes an image carrier and a waste toner receiver. The cleaning member includes a rotation member that is rotated in a forward rotation direction. The cleaning member is positioned near the opening in the housing and removes residual toner from the surface of the image carrier. The contact member is positioned so as to be in contact with an outer peripheral surface of the rotation member. The torque limiter is located on a rotation shaft of the rotation member and is capable of rotating independently of the rotation shaft when a torque that is greater than or equal to a predetermined torque is applied to the torque limiter. The urging member applies an urging force to the torque limiter in a reverse rotation direction. | 06-05-2014 |
20140294432 | Intermediate Transfer Unit for Stably Charging and Cleaning - An intermediate transfer unit includes an intermediate transfer belt, a plurality of rollers, a cleaning unit, a brush unit, and a pressing member. The brush unit is located at the outer circumferential surface part of the intermediate transfer belt in contact with the roller. The brush unit is located at upstream of a contacting part with the cleaning unit in a running direction of the intermediate transfer belt. The brush unit is configured to impart electric charge to the remnant toner by a contact friction with the outer circumferential surface of the intermediate transfer belt. The pressing member is configured to press the brush unit along a direction of contact/separation with respect to the outer circumferential surface of the intermediate transfer belt. | 10-02-2014 |
