A computer determines whether destination information is included in permission target information. The destination information indicates a destination to which a file stored in a storage device is transferred. The permission target information includes information indicating a target permitted to access the file. The computer prompts before the file is transferred, upon determining that the destination information is not included in the permission target information, a user to input whether to permit the transfer. The computer adds the destination information to the permission target information upon receiving, via an input device, a permission input for permitting the transfer. The computer transfers the file upon receiving the permission input.

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.

According to one embodiment, a manufacturing method includes performing lithography processes for manufacturing a semiconductor device that includes a three-dimensional stacked device. The stacked device includes layers stacked above a substrate. Each of the layers includes a device circuit. The lithography processes include a lithography process for forming a lower layer of the layers by using a first original plate that has quality not less than a certain level. The first original plate is selected from original plates. Each of the original plates includes a pattern corresponding to the device circuit. The original plates are ranked according to quality based on defect. The lithography processes further include a lithography process for forming a higher layer of the layers by using a second original plate that has quality lower than the certain level. The second original plate is selected from the original plates.

A method forms ball recirculation and rolling grooves at an inner circumferential surface of a nut for ball screw use in a state free of deviation in axial, circumferential, and radial nut directions. A flange end face is formed with a concave part, then an inner circumferential surface of a blank and an end face and outer circumferential surface of the flange are continuously ground. Due to this, the coaxiality of the blank inner circumferential surface and the flange outer circumferential surface, and the perpendicularity of the flange end face to the blank inner circumferential surface, are made smaller. The blank is plastically worked to form the ball recirculation groove and is cut to form the ball rolling groove while using the concave part as a phase reference, the end face as an axial direction reference, and the outer circumferential surface as a radial direction reference.

A switch unit includes an upper case that has an operation portion attached therein; a circuit board that has a switch attached thereto that is able to switch contact points by operation of the operation portion; and a lower case that fits into the upper case such that the lower case is surrounded by the upper case, and that accommodates the circuit board between the upper case and the lower case. A draining portion is provided at a side surface of the upper case, and the draining portion is integrally formed with a sidewall forming the side surface and protrudes downward, and has a width that gradually narrows from the top to the bottom thereof.

A method forms a concave constituting a ball return passage directly on an inner circumferential surface of a nut blank by plastic working without damaging a die. Letter S shaped concaves are formed on an inner circumferential surface of a nut blank, by pressing by use of a die having a blank holder, a cam driver, cam sliders, and a cylindrical member. The cam driver has inclined surfaces having the same angle of inclination as the cam sliders. The cam sliders have letter S shaped convexes corresponding to the letter S shaped concaves, and are held by through holes, respectively. When the cam driver is pressed from the top thereof, the cam sliders move outwardly in the radial direction, respectively, and the letter S shaped convexes push the inner circumferential surface of the nut blank for plastic deformation.
