An optical scanning unit irradiates a polygon mirror with a plurality of light beams emitted from a light source according to image data, and scans and exposes a plurality of photoreceptors with the plurality of light beams as scanning lights. The optical scanning unit comprises a primary optical system unit including an optical system that emits the plurality of light beams, which are emitted from the light source toward the polygon mirror, and a secondary optical system unit including an optical system that emits the light beams, which are reflected by the polygon mirror toward the photoreceptors. The arrangement is such that the primary optical system unit is fitted removably to the secondary optical system unit, and that a combined unit of the primary optical system unit and the secondary optical system unit is removably fitted to an image forming apparatus having the photoreceptors.

A method for fabricating a semiconductor device includes the following steps. At first, a Ru or RuO2 film and a SiO2 layer are formed over a Si substrate in that order. Then, a resist pattern is formed on the SiO2 layer and is then provided as a mask to etch the SiO2 layer to form a contact hole. The Ru or RuO2 film is exposed at the bottom of the contact hole. Subsequently, a plasma ashing is performed using an ashing gas prepared by mixing O2 with N2 where the composition ratio of N2 is 50% or more at a substrate temperature of 200° C. or more for ashing the resist pattern. Consequently, the present invention allows the ashing of the resist pattern over the Ru or RuO2 film at a high selectivity to prevent the Ru or RuO2 film from becoming disappeared.

Each the contact terminal includes a plurality of contact units stacked with each other, wherein contact point sections of the respective contact units are distributed to disperse in lengthwise direction of the contact terminal within the corresponding contact pad. The distal end of the innermost contact unit in the plurality of stacked contact units extends to a position at which it is not entangled with the distal end of the adjacent contact unit.

The first card accommodating portion for accommodating the first card and the second card accommodating portion for accommodating the second card are formed in the connector housing in such a way that a part of the first and second card accommodating portions can be used commonly by the first and second cards. This construction allows two or more kinds of cards with different external shapes and different contact pad positions to be inserted into the connector from one and the same card insertion slot, thus reducing the space occupied by the card connector.

A first slidable assembly provided in an image reading unit of a digital copier has the slider pieces attached to the frame of the slidable assembly body thereof so that the slider pieces will move sliding over the guide elements. The upper part of the slider piece is an insert portion which is fitted through a passage hole formed in the frame and has engaging portions that pass through the passage hole as being deformed and become engaged with the rim of the passage hole.

In a production method of a rotor, a lower layer slot insulator is held at a slot insulator holding portion of a combining jig. A lower layer coil bar is inserted into a coil inserting path of the combining jig and is combined integrally with the lower layer slot insulator by being pushed together. Thereafter, the combined set is set in a coil integrating path of a coil holding member. The coil holding member is attached to a coil inserting device along with an armature core. The lower layer slot insulator and a lower coil trunk are integrally inserted into a slot of the armature core by pushing the lower layer coil bar in the coil integrating path. The lower layer coil trunk and an upper layer coil trunk may be formed integrally with respective coil arms as a single coil bar.

An optical positional information detection apparatus for detecting a position indicated by a pointer on a display surface. The optical positional information detection apparatus includes an imaging unit that captures an image of one or more pointers situated within a predetermined distance from the display surface; an image obtaining unit that obtains a first image captured by the imaging unit and a second image captured by the imaging unit; a movement distance calculation unit that uses a first feature amount based on the first image in which first pointers are captured and a second feature amount based on the second image in which second pointers are captured so that the movement distance calculation unit calculates a movement distance from the first pointers to the second pointers; and an association unit that associates the second pointers with the first pointers based on a limitation on the movement distance.
