Title: Solenoid valve
Inventor: ITOU MIKIO
IPC: F16K31/11
Filed: 1983-12-01
Abstract: PURPOSE:To reduce the dimension of projection in the installation state onto a machine apparatus by setting the dimension of projection from a valve body to be short enough to be necessary for accommodating a coil and a fastening tool. CONSTITUTION:A hollow cylindrical body 15 into which a movable iron core 20, push pin 23, etc. are accommodated is installed onto a valve body 3. In this case, a screwing part 41 is screwed into a tapped hole 14 by holding the cylindrical body 15 by hand. Then, an electromagnet body is applied onto the outer peripheral side of the cylindrical body 15. Then, a fastening tool 33 is screwed with a screw part 44, and then tightened until the pressing part 35 presses a case body 27. Since the tightening-tool installation part 45 of the cylindrical body 15 is formed in concaved form, it is enough for the dimension of projection from a valve body 1 to be short so as to be necessary for the accommodation of a coil 24 and the tightening tool 33.

Title: Fabrication of semiconductor thin film
Inventor: AIZAKI HISAAKI
IPC: H01L21/268
Filed: 1982-12-28
Abstract: PURPOSE:To contrive single crystallization over large area by performing recrystallization with scanning polycrystalline or amorphous semiconductor thin film on an insulating film by laser beam showing multipeak distribution thereby giving precedence to crystal grains at specified positions as nuclei of recrystallization. CONSTITUTION:A silicon oxide film 20 is formed on surface of a single crystal silicon substrate 10 by thermal oxidation or the like and next, a polycrystalline silicon film 30 is formed over the whole surface. Meanwhile, laser beam 40 having Gaussian distribution of intensity permeates through a quartz birefringence plate 50 once and separates into two beams. When the polycrystalline silicon film 30 is scanned by multipeak-type laser beam 41 in the scanning direction 1, it is once fused and then recrystallized. The direction 70 in which the recrystallization proceeds is determined according to shape of the laser beam which gathers toward the center in end parts 61 and expands toward the end parts in a central part 62. Accordingly, it is impossible to contrive single crystallization over large area in the end parts, however that is possible in the central parts 62 as crystal grains present at the central positions of twin-peak type distribution of intensity become nuclei of recrystallization.

Filed: 1987-09-14
Abstract: PURPOSE:To contrive to improve the reliability by providing a flow control part for controlling a flow so that an air flow containing fine resin particles generated at the time of ultrasonic welding does not turn to the direction of a disk rotational area, in the vicinity of a welding part of a case. CONSTITUTION:In the tip part of a boss part 15 of the upper case 1a, an annular welding margin is formed. In this state, at the time of joining the case 1a and the lower case 1b, the boss part 15 of the front is inserted into a cylindrical part 16 of the front corresponding thereto, and between the boss part 15 and the cylindrical part 16, an ultrasonic wave is applied and welding is executed, and in this case, the upper face of a circular arc-like rib 18 abuts on the inside of the case 1a. Accordingly, air containing fine resin particles does not flow in the direction of a disk rotational area, but flows to the side opposite to the disk rotational area. In such a way, it does not occur that the fine resin particles generated at the time of ultrasonic welding adhere to the surface of the disk, therefore, the operation reliability is improved.

Title: Laser printer
Inventor: SAKAI YUKIO
IPC: G03G15/22
Filed: 1983-12-03
Abstract: PURPOSE:To prevent a photosensitive body from being over-exposed to laser light, by a method wherein the condition in which the incidence of laser light modulated by an image signal on a photosenstive body is interrupted and the condition in which the incidence is permitted are switched from one to the other by a shutter means. CONSTITUTION:The laser light emitted from a semi-conductor laser 1 and polarized by a polygonal polarizer 3 is scanned on the photosensitive body 9 through a reflector 5. At this time, a shutter 19 for preventing black solid printing interrupts the light of a destaticizing lamp 6. When the irradiation of an image part with light is completed, the shutter 19 is turned so that the laser light is interrupted and the light from the lamp 6 is permitted to be incident on the photosensitive body 9. By previously setting the shutter 19 so as to interrupt the laser light when the photosensitive body 9 is stopped, the body 9 can be prevented from being over-irradiated with the laser light. The shutter 19 can be used both for preventing black solid printing and for interruption the laser light, and the lamp 6 functions also as a light source for a lamp for preventing black solid printing.

Title: Color filter substrate and its production and liquid crystal display element formed by using the same and its production
Inventor: MIYAZAKI DAISUKE
IPC: G02F1/1335
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To lessen the occurrence of the variation in the sizes of spacers due to mispositioning at the time of laminating colored layers for spacers in the case the spacers of a liquid crystal display element are formed by laminating the colored layers for the spacers. SOLUTION: The areas of the surface in contact with at least adjacent two layers among the colored layers for spacers of plural colors of the spacers 3 are made different from each other. For example, the areas of the surfaces in contact with the first layer 3R and the second layer 3G are so determined that the area of the second layer 3G is smaller than the area of the first layer 3R. As a result, even if a mispositioning at the time of forming the colored layers for display and the colored layers for spacers arises, the other layer is eventually formed within the area of the layer having the largest area when the area of the surface in contact with adjacent two layers is a layer having the smallest area. The occurrence of the variations in the sizes of the spacers 3 is thus lessened.
