A push button switch 1 is so constructed as to disengage the movable contacts 55b, 56b from the fixed contacts 55a, 56a through operation of the push button 2 held in the switch case 3. A first leaf spring 550 is provided in the switch case 3 to act as an opening-biasing means to bias the movable contacts 55b, 56b away from the fixed contacts 55a, 56a. The movable contact 55b is disposed at an end of the first leaf spring 550 and adapted to engage with and disengage from the fixed contact 55a. The first leaf spring 550 is adapted to be at a position where the movable contact 55b is open relative to and disengaged from the fixed contact 55a at zero displacement of the first leaf spring 550.

A predetermined pattern containing a plurality of gate patterns, in the process of formation thereof, is classified into fine gate patterns and the other patterns (S102), and a hard mask film is formed on a process target film (S106). Next, a first resist film having a fine first pattern is formed on the hard mask film, and the hard mask film is then patterned (S108). Thereafter, a resist film having a separate pattern is formed on the hard mask film, and a process target film is selectively dry-etched through the hard mask film and the resist film used as masks (S110 and S112).

A fixing roller 30, which has an internal heating device and is supported to rotate around a cylindrical shaft 40, and a pressure roller 81 whose circumferential face presses against the fixing roller 30, and which is supported to rotate around the pressure roller axle 82, are mounted in a housing 11, so that, by passing paper P to which a toner image has been transferred, a fixing process is performed on this toner image. The fixing roller 30 is mounted in the housing 11 by heat resistant bushings 50, which are fitted on both ends of the cylindrical shaft 40. Annular grooves 41 are arranged on the cylindrical shaft 40 for receiving C-shaped retaining rings 70, for preventing the heat resistant bushings 50 from coming off. The heat resistant bushings 50 and the retaining rings 70 engage with each other to rotate in unison around the cylindrical shaft 40.

When an operator applies a removing force to turn a switch portion b in a direction C2, a projection a4 abuts against a slope b71 so that the removing force as a reaction is applied to the slope. The removing force is divided into a component working along the slope b71 and a component F working in a same direction as a center axis X. Thus, the removing force is converted into a force F in the same direction as the center axis X. By means of the force F in the same direction as the center axis X, a pushbutton support b6 is moved downward as accordingly moving a movable contacts b9 away from a fixed contacts b12 via a contact axis b5.

A reticle system includes a reticle film having thereon a plurality of scale patterns each having a plurality of scale marks plotted therein, and a shield film having a plurality of pinholes each disposed corresponding to one of the scale patterns. A light emitted from a point light source having an effective coherent factor “x” and passing the reticle film at a scale mark “x” or below “x” in one of the scale patterns passes through the corresponding pinhole. After transferring the scale patterns onto a wafer surface, the effective coherent factors are read from the maximum scale marks for respective scale patterns on the wafer surface. The dispersion of the coherent factors can be calculated therefrom.

The present invention provides a mask for measuring an optical aberration, the mask including at least a measuring pattern comprising plural pattern parts being separated from each other, wherein the plural pattern parts provide individual widths which are simply increased on first and second directional axes non-parallel to each other and vertical to a plane of the mask, provided that the width of each of the plural pattern parts is unchanged at least on the first and second directional axes.
