Filed: 1990-06-21
Abstract: PURPOSE:To constitute this optical scanner at a low cost without using an expensive refractive index distribution lens by disposing a cylindrical lens array consisting of the same constitution as an optical waveguide array on the emitting end of the optical waveguide array. CONSTITUTION:A condensing means 16 constituted in the emitting end 15b of an optical waveguide array is condensed in the parallel direction of the emitting end by a cylindrical lens array 17, and also, condensed in the direction vertical to the parallel direction of the emitting end by a cylindrical lens 18, broadening of a light beam is made small and it is allowed to reach on a photosensitive drum 19. Accordingly, since respective adjacent picture elements are interfered with each other, the image quality is not degraded. In such a manner by using only a part of an optical waveguide array 15 and the cylindrical lens 18 and since it is unnecessary to an expensive refractive index distribution lens array for a condensing means of the emitting end, the optical scanner is constituted at a very low cost.

IPC: B41J29/38
Filed: 1990-06-22
Abstract: PURPOSE:To dispense with data repair work or sheet alignment process during next power supply making, if a power supply is shielded in any state by holding a power supply making state when a power supply switch is turned ON, and delaying the power supply shutoff until a specified action is completed if the power supply switch is turned OFF. CONSTITUTION:When a power supply is turned ON using a power supply switch 2, the state of power supply making is maintained by a holding means 3 consisting of, for example, a self-holding circuit. Then the power supply is shut off by a control signal connected from a release means 4 under the control of a control means 6. On the other hand, the ON/OFF state of the power supply switch 2 is transferred to the control means 6. If a fact that the power supply is shut off by the power supply switch 2 is recognized by a signal from a detection device, the control means 6 interprets whether a specified unit action is completed, and suspends the drive of a release means 4 until the specified action unit is completed and delays the power supply shutoff, if the specified action unit is not yet completed.

Title: Preparation of semiconductor device
Inventor: KANEKO KAZUO
IPC: H01L21/027
Filed: 1980-11-25
Abstract: PURPOSE:To improve target signal level by etching a target pattern part in a process of photoresist so as to form a target. CONSTITUTION:On an oxide film 2 to form a gate insulator film, which is formed on an Si substrate 1, a membraneous conductive film 3 which is hard to etch by an HF etching liquid is formed simultaneously with formation of a gate and wiring. Next, after a CVD film 4 to serve as an inter-layer insulator film is formed, a target part is etched in a process of photoresist to form a target, which is employed for subsequent mask alignment. In this case, when the film 4 is formed in the place of the film 3 where there is a difference in level, the film thickness turns different between parts (a) and (b), where (a) is thinner than (b). Accordingly, by etching the film 4, the film 2 is turned to be in an overhang state 5, and thus a value of high target signal level is obtained by scanning of mask alignment.

IPC: B41C1/14
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To lengthen a lifetime of a product by covering an inner peripheral surface of an opening for cream solder printing with a thin film of a titanium oxide, thereby remarkably improving a mold releasability. SOLUTION: The screen mask 10 comprises thin films 16 of a titanium dioxide each having a thickness of about 0.1 μm and coating an inner periphery 12A of an opening 12 for cream solder printing, a front surface 14A and a rear surface 14B. The each film 16 is formed by coating a surface of a raw material formed with the opening 12 of the mask 10 with a fine powder of the titanium dioxide by spraying, dipping or the like, then heating to sinter it, and fixing it. Thus, when a cream solder is brought into contact with a surface of the titanium dioxide in the state that a physically adsorbed water is input to a water storage substance on the surface of the titanium dioxide, an OH group of an alcohol and an oil component contained in the solder are positively held on the surface of the titanium dioxide as the adsorbed water, thereby remarkably reducing a friction with the solder.
