A process cartridge comprises a photosensitive drum and a developing roller. A coupling member is provided adjacent to one axial end of the developing roller. The coupling member includes a driven portion, and an intermediary portion configured and positioned to engage with the driven portion. The intermediary portion is also configured to be movable relative to the driven portion in a direction crossing the axis of the developing roller while maintaining engagement with the driven portion. The coupling member further includes a driving portion configured and positioned to receive a driving force for rotating the developing roller. The driving portion is also configured to engage with the intermediary portion, and to be movable relative to the intermediary portion in a direction crossing the axis of the developing roller while maintaining engagement with the intermediary portion.

A ball screw is provided in which an outer circumferential formation is formed at a portion facing a ball circulating passage out of outer circumferential surface of a nut. The ball screw includes: a screw shaft having on its outer circumferential surface a screw groove; a nut having on its inner circumferential surface a screw groove facing the screw groove; a plurality of balls rollably loaded in a spiral ball rolling passage formed by both screw grooves; and a ball circulating passage to return the balls from a start point to an end point of the ball rolling passage for recirculation. The ball circulating passage is a concaved groove formed by concaving a groove on a part of the cylindrical inner circumferential surface of the nut by plastic working. Then, a flange is integrally provided at a portion facing the ball circulating passage and the screw groove.

A method of generating mask data, for a set of masks used to transfer a pattern for delineating a circuit pattern of a semiconductor integrated circuit, includes preparing design data having a design pattern corresponding to the pattern to be transferred on a semiconductor substrate; generating resized data by enlarging the design data by a resizing quantity; generating first mask data by filling a space area having a space width of a space quantity or less of the resized data; and generating second mask data, to be aligned with the first mask data, having a window portion for selectively exposing an area determined by enlarging the space area by the resizing quantity.

Since centers of a second gear, a fourth gear and a sixth gear coincide with each other and are disposed rotatably round a circumference of the same long shaft, a compact configuration can be realized while using a gear train of five gears to obtain a reduction gear ratio of a high gear ratio. The configuration in which the three gears have the same rotational center shaft in the way described above in an actuator which incorporates a plurality of gears is advantageous in that the number of center shafts is reduced and that the number of supporting holes in a housing which support center shafts is reduced.

Disclosed is a method of driving a plasma display panel. In this method, one field corresponding to one image is divided into a plurality of sub-fields, and at least one second sub-field is arranged after a first sub-field. In the first sub-field, the method comprises a first step of forming wall charges with negative polarity near the scanning electrode and forming wall charges with positive polarity near the common electrode and the data electrode; a second step of adjusting an amount of the wall charges with negative polarity near the scanning electrode and an amount of the wall charges with positive polarity near the common electrode and the data electrode; a third step of generating a writing discharge in a selected display cell of the display cells; a fourth step of generating light emission for display; and a fifth step of erasing a part of the wall charges in the display cell which emits light in the fourth step. In the second sub-field, the method comprises the same steps as the third, fourth and fifth steps. A potential difference between a scanning electrode and a common electrode in each of the fifth steps in the first and second sub-fields is set to be smaller than a potential difference between a scanning electrode and a common electrode in each of the third steps in the first and second sub-fields.

A process cartridge comprises a photosensitive drum and a developing roller. A coupling member is provided adjacent to one axial end of the developing roller. The coupling member includes a driven portion, and an intermediary portion configured and positioned to engage with the driven portion. The intermediary portion is also configured to be movable relative to the driven portion in a direction crossing the axis of the developing roller while maintaining engagement with the driven portion. The coupling member further includes a driving portion configured and positioned to receive a driving force for rotating the developing roller. The driving portion is also configured to engage with the intermediary portion, and to be movable relative to the intermediary portion in a direction crossing the axis of the developing roller while maintaining engagement with the intermediary portion.

A block film is formed on a region which includes a region of an insulating layer where a first hole is to be formed, and in which no second hole is to be formed, and a resist film having openings for forming the first and second holes is formed on the block film and insulating layer. Etching is performed by using the resist film as a mask, thereby forming the first hole in the block film and insulating layer, and the second hole in the insulating layer. The depth of the first hole from the upper surface of the insulating layer is smaller than that of the second hole, so the first hole does not reach the semiconductor substrate.

A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes a photosensitive drum, and a developing roller for developing a latent image. A development coupling portion is provided that includes a driven portion. The development coupling portion also includes an intermediary portion configured and positioned to engage with the driven portion, and to be movable relative to the driven portion while maintaining engagement with the driven portion. The development coupling portion still further includes a driving portion configured and positioned to engage with the intermediary portion, and to be movable relative to the intermediary portion in a direction crossing the axis of the developing roller while maintaining engagement with the intermediary portion.
