A structure for providing relative positioning of a rotary detecting shaft of a rotary detecting device, such as a rotary encoder or a rotary switch, and a rotary shaft, is disclosed. There is an X-Y stage comprised of a plate, a first sliding plate and a second sliding plate. The rotary detecting device is fastened to the second sliding plate of the X-Y stage, and the plate is fastened to a frame to which the rotary shaft is mounted. The rotary detecting shaft is connected to the rotary shaft by a joint unit. According to the invention, aligning the rotary shaft with a rotary detecting shaft is carried out automatically by the movement of the first and second sliding plates as the rotary detecting shaft and rotary shaft are connected. Further, if exact alignment is not achieved prior to rotation of the rotary shaft, the rotational deviation of the rotary detecting shaft and rotary shaft will be eliminated by the further movement of the X-Y stage. This results in reduced rotational torque on the rotary detecting shaft and, therefore, reduced damage to bearings and other parts, and increased accuracy of detection.

A semiconductor LSI device formed in a semiconductor substrate comprising source/ drain regions of a MOSFET, polycrystalline silicon conductor to be connected to the source/drain region, and a silicide layer interposed between the source/drain region and the polycrystalline silicon conductor. Silicide intrudes into silicon bulk through an oxide film on the silicon substrate surface, assuring contact of low resistance, while lateral resistance of the source/drain region formed in the semiconductor substrate is also reduced. Reduction of contact/connection resistances is accomplished in a high density LSI which is thus imparted with an improved high-speed performance.

A seal includes a photoreceptor contacting portion to contact a photoreceptor, and a charge roller contacting portion to contact a charge roller. The photoreceptor contacting portion removes toner on the photoreceptor, and the charge roller contacting portion removes the toner on the charge roller, when the seal is mounted along the photoreceptor.

Disclosed is a micrometer with an improved a heat-insulating property. A micrometer 10 with a U-shaped frame 20 supporting an anvil 12 and a spindle 14 at tip end portions thereof so that the anvil 12 and the spindle 14 are coaxially opposed to each other is provided with a heat insulating cover 50. The heat insulating cover 50 is shaped to accommodate a bottom portion of the frame 20, and is detachable with respect to the frame 20. The heat insulating cover 50 covers a bottom face 22 of the frame 20 while supporting the bottom portion of the frame 20 by sandwiching from both sides of the frame 20.

A fixing device includes a fixing roller and a pressing roller that are in pressure contact with each other. A separating plate is placed opposite to the fixing roller with a certain gap in between them. Positioning portions are installed on the separating plate to be in contact with width-direction ends of the fixing roller for determining the gap. The positioning portions are arranged such that edges of contact portions of the positioning portions on the width-direction center side in contact with the fixing unit are positioned outside an image area and inside a paper-passing area for a recording medium of a maximum passing-capable size.

A developing device includes a main body that is arranged between a pair of supporting members and includes a developing roller. Both end portions of the developing roller are supported by the supporting members in a first direction in which the developing roller is movable toward and away from an image carrier. A groove is formed on each of the supporting members. Either one of an end portion of the developing roller and a bearing that supports the end portion is inserted into the groove. Either one of at least one of the end portions of the developing roller and at least one of the bearings is movable in the groove in a second direction that intersects the first direction.

A fixing device includes a pair of first frames that support an axis of each of a fixing roller and a pressing roller and a pair of second frames arranged in parallel to an axial direction of the fixing roller to connect the first frames to each other. The second frames include cover portions that cover an upper peripheral surface and a lower peripheral surface of the rollers. A coupling member couples the cover portions to each other and has a bridge structure between the cover portions.
