20090100861 | COMPRESSOR - A stator core of a motor has a plurality of oil return passages extending through one surface and the other surface of the core. On the other surface of the stator core, a hydraulic diameter of each oil return passage is 5 mm or larger, and a ratio of a total area of the oil return passages to an area of a virtual circle having a diameter equal to a maximum outer diameter of the stator core is 5 to 15%. Lubricating oil accumulated on the other surface side of the stator core is returned to an oil reservoir through the oil return passages, and shortage of oil in the oil reservoir is prevented. Furthermore, a cross sectional area of the stator core can be securely kept, and motor efficiency is maintained. | 04-23-2009 |
20090123308 | COMPRESSOR - A compressor has stator of a motor is installed in a closed container, on two planes normal to the center axis | 05-14-2009 |
20090285702 | COMPRESSOR - A discharge port of a compression element is positioned inside an outer circumferential surface of a stator, as seen looking in a direction of a rotation axis of a shaft, and overlaps the stator, as seen looking in a direction orthogonal to the rotation axis of the shaft. Accordingly, refrigerant gas discharged from the compression element can be made to flow mainly into spaces inside the outer circumferential surface of the stator. | 11-19-2009 |

20110211871 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image bearing member; a belt unit which is rotatable in contact with the image bearing member and which is capable of being drawn out of a main assembly of the image forming apparatus; a cam for switching a position of the belt member relative to the image bearing member; a motor for rotating the cam; control means for controlling the motor to contact and space the belt member relative to the image bearing member; a lever movable between a first position in which the belt unit is fixed to the main assembly of the image forming apparatus and a second position in which the belt unit is capable of drawn out of the main assembly of the image forming apparatus; and a spacing mechanism for spacing the belt from the image bearing member by converting movement of the lever from the first position to the second position to a rotation of the cam, when the belt member is contacted to the image bearing member. | 09-01-2011 |
20120018945 | SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS - An image forming apparatus including a sheet conveying portion which conveys a sheet to be formed with an image, and an abutment member which is abutted by the tip end of a sheet conveyed by the sheet conveying portion, and movable to a first attitude of being abutted by the tip end of the sheet being conveyed, and to a second attitude of allowing passage of the sheet and being in the state of abutting the surface of the sheet, wherein the abutment member in the second attitude abuts a part which is outside an image forming region and on the sheet surface having the image forming region in a central part in a width direction orthogonal to a sheet conveying direction. | 01-26-2012 |
20130134664 | SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS - An image forming apparatus including a sheet conveying portion which conveys a sheet to be formed with an image, and an abutment member which is abutted by the tip end of a sheet conveyed by the sheet conveying portion, and movable to a first attitude of being abutted by the tip end of the sheet being conveyed, and to a second attitude of allowing passage of the sheet and being in the state of abutting the surface of the sheet, wherein the abutment member in the second attitude abuts a part which is outside an image forming region and on the sheet surface having the image forming region in a central part in a width direction orthogonal to a sheet conveying direction. | 05-30-2013 |
20140376949 | IMAGE FORMING APPARATUS - An image forming apparatus includes a fixing unit heating an image formed on a recording medium and disposed along a conveying path conveying the recording medium. The conveying path includes a first guide plate, discharge guide plate portions and second guide plate portion as conveyance guide plates guiding the recording medium. Partition walls and vertical walls are disposed at positions facing these guide plate portions. The air current guide portion guides air taken in from intake ports through an intake guide portion between the respective guide plate portions and each walls. | 12-25-2014 |
20150055992 | IMAGE FORMING APPARATUS - In a constitution provided with no primary-transfer roller, in order to ensure a contact length between each of photosensitive drums and an intermediary transfer belt, the photosensitive drums are disposed in entering amounts at a plurality of levels with respect to a stretching surface of the intermediary transfer belt, and therefore an apparatus is upsized in a height direction. In order to avoid this, four image bearing members are arranged, along the intermediary transfer belt, in the same entering amount with respect to the stretching surface of the intermediary transfer belt, and a depressing member for depressing a belt surface between two central image bearing members toward an outside is provided. | 02-26-2015 |
