A timepiece having a movement, a substantially cylindrical case that houses the movement, a bezel that holds the outside edge part of a crystal and is fastened to the case, and a back cover that is fastened to the opposite side of the case as the side to which the bezel is disposed. The case has a plurality of movement fastening units for fastening the movement by means of screws, a plurality of bezel fastening units for fastening the bezel by means of screws, and a plurality of back cover fastening units for fastening the back cover by means of screws. The screws disposed to the movement fastening units, the bezel fastening units, and the back cover fastening units are substantially aligned with the axial direction of the case. The movement fastening units, the bezel fastening units, and the back cover fastening units are respectively disposed at different positions in the circumferential direction of the case, and are disposed to a fastener reference position substantially similar in shape to the shape of the outside of the movement facing the case.

A semiconductor device manufacturing method is a method of forming a semiconductor device that includes a cell part that includes plural transistor cells in each of which a gate of a trench type is formed in a semiconductor layer, and diffused layers are formed on both sides of the gate, and a guard ring part that surrounds the cell part. The semiconductor device manufacturing method includes forming an interlayer dielectric film on a surface of the semiconductor layer in which the gate and the diffused layers are formed; reducing a thickness of the interlayer dielectric film formed in the cell part through etch back; forming a contact part having a shape of a hole or a groove in the interlayer dielectric film at a position above the diffused layer; and forming a metal film on the interlayer dialectic film.

An image forming device has a conveying member, a light source, a photo-sensor, a shutter member, a shutter driving unit, a reflecting member and a judging member. The shutter member located between the photo-sensor and the conveying member is moved between a close position and an open position. The reflecting member provided on shutter member reflects light emitted by the light source when the shutter member entirely or partially shields the light emitted by the light source and directed toward the conveying member, and an intensity of light reflected by the reflecting member and detected by the photo-sensor varying depending on a position of the shutter member. The judging member judges whether the shutter member is located at the close position or the open position and whether the conveying member is present or absent based on the intensity of the light detected by the photo-sensor.
