摘要:
An object of the present invention is to obtain uniform shape of a thin film of an electronic device having a thin film. The present invention comprises the steps of: forming an substantially linear droplet pattern by applying an ink-jet head having a plurality of nozzles which discharge a droplet of a solvent containing a functional thin-film material to provide a substrate with droplets from at least part of a plurality of the nozzles; and drying the droplets which have been provided on the substrate, the drying step is performed by intake-exhaust means which is positioned in a direction orthogonal to the substantially linear droplet pattern from the ink-jet head and which has an exhaust opening wider than the approximate linear droplet pattern.

A spark plug for internal combustion engines provided with a noble metal tip on the pointed top of a spark plug center electrode. The noble metal tip is welded to the center electrode top end by heating and pressing the portion to be welded. After the welding, the center electrode is shaped to provide the pointed top. The noble metal tip is a platinum alloy consisting of platinum of 85 through 70 in weight percentage and iridium of 15 through 30 in weight percentage.

In an exposing method which illuminates, by illumination light, a mask having apertures arranged in matrix and a latticed light shielding portion, projects the mask on an object to be projected via a projection optical system, and thus forms a dark portion pattern image at a position conjugate in relation to intersections of a lattice of the light shielding portion, an available light source shape of the illumination satisfies a specific condition. Therefore, it is possible to exposure a two-dimensional periodic pattern to a theoretical limit pitch being the same as that of a one-dimensional periodic pattern, and it is also possible to secure a depth of focus sufficiently.

A rotary member mounting structure is configured for mounting a speedometer worm gear closely adjacent to a drive gear that is supported on an output shaft. The rotary member mounting structure basically has a rotation preventing structure, a first fastening ring and a second fastening ring. The rotation preventing structure is configured to prevent the drive gear from rotating relative to the output shaft 1 and to prevent the worm gear from rotating relative to the output shaft. The first fastening ring is configured to prevent the drive gear from sliding axially toward the worm gear and to prevent the worm gear from sliding axially toward the drive gear; and a second fastening ring is configured to prevent the worm gear from sliding axially in the direction opposite (i.e., away from) the drive gear.

An edge of a material to be washed is held between forked portions of a vibration transmitting portion. An ultrasonic vibrator is attached to an enlarged portion of the vibration transmitting portion, and the ultrasonic waves supplied from the ultrasonic vibrator irradiate the washing liquid flowing to the forked portion, and the edge of the material to washed is washed by the ultrasonic wave and the washing liquid.
