Title: Semiconductor integrated device
Inventor: FURUYA YASUSHIGE
IPC: H03B5/30
Filed: 1991-09-02
Abstract: PURPOSE:To obtain reliable and extremely compact oscillator using a vibrator with high oscillation accuracy at a low cost by integrating an vibrator with an oscillation circuit to oscillate a vibrator and connecting a plurarity of electrodes of the vibrator with the oscillation terminal of the oscillation circuit. CONSTITUTION:Electrodes 2 and 3 formed by the evapolation of the aluminum are laminated in a comb shape on the surface of the piezo-electric substrate. This oscillation vibrator 1 operates in a mode called by the SAW (surface acoustic wave) outgoing, whose oscillation frequency is decided by the distance between the electrodes 2 and 3. The stability of the oscillation is in the middle of a crystal oscillator and an LC oscillator, having the characteristic obtaining the high basic frequency (more than 100MHz). It is immune to the vibration and shock by the structual feature that a surface with the electrodes is fixed to the opposite bottom. It is convenient to use it while attached to the upper layer of the semiconductor integrated device. The contact (through hole) technology to be used for the normal semiconductor formation can be applied to the electrodes 2 and 3.

Abstract: PURPOSE:To improve reliability in a information holding characteristic and the density of integration, in a semiconductor integrated circuit device having a memory function, by constituting the wirings in an at least memory cell array with a conducting layer, which is formed by a chemical vapor deposition technology. CONSTITUTION:Semiconductor regions 4 constitute information storing capacitor elements 4 and are provided beneath the entire area of the elements C. Barrier regions (barrier structure) are constituted. As conductor plates 7, a material, in which resistance-value decreasing impurities (phosphorus or arsenic) are diffused in, e.g., a polycrystalline silicon film, which is formed by a CVD technology, is used. The wirings such as the conductor plates 7, gate electrodes 10, word lines 10 and data lines 16 in a memory cell array are constituted by conducting layers, which are formed by the CVD technology. The wirings are formed by vapor phase reaction caused by a material, which is used for forming the wirings and supplied as a form of source gas. Thus purification of radioactive elements such as U and Th can be readily performed. The wirings in the memory cell array can be constituted with the highly pure conducting layer, and soft errors can be prevented.

Title: Phosphor screen forming method
Inventor: MURATA TOSHIICHI
IPC: H01J9/227
Filed: 1982-12-17
Abstract: PURPOSE:To simplify process and to improve productionability by forming black stripe through off-set printing while forming phosphor substance stripe through screen printing method thereby forming phosphor face accurately on the face of planar glass. CONSTITUTION:Off-set printing is preferable for forming black stripe. Especially, gravure printing method is preferable. If the thickness is insufficient, lap printing is required. For forming phosphor substance stripe, silk screen printing is preferable because of quite thick thickness. In case of phosphor substance, R, G, B are composed of fine white powder of 10-20mu, so it is quite difficult to produce ink but suitable to produce paste. Since screen printing method has low accuracy, silk screen print should be at least 25 times, ideally 81 times in area ratio to improve stripe pattern accuracy. Consequently productionability is improved, counter measure for polution is simplified while quality is stabilized.

Title: Prize winning ball discharger of pinball machine
Inventor: FURUKAWA MOTOO
IPC: A63F7/02
Filed: 1989-08-29
Abstract: PURPOSE:To completely prevent prize winning balls from an incontinent accident and shorten a time taken for a prize winning ball discharge action by providing a rotation control member entering a track on which it engages the next engaging part right before it is separated from an engaging part and discharging one prize winning ball by one directional action of the rotation control member. CONSTITUTION:A rotation control member 13 is attracted to an excited electromagnet 15b and a lock piece 13a is moved to get out of an engaging part 11a1. Then, a ball cut member 18 loses a lock to be rotated by ball pressure. Since the lock piece 13a enters a track on which it engages the next engaging part 11b1 right before it gets out of the engaging part 11a1, the ball cut member 8 is rotated 36 deg. and stopped. One pinball Ba1 engaging an engaging lug 8a3 is discharged from a ball path 7a by the rotation. A pinball Bb1 on another ball path 7b then engages an engaging lug 8b3 of a rotor 8b, but the position of a pinball Bb1 is lowered to the position of pinball Ba1 and stopped by 36 deg. rotation of the ball cut member 8. Thus, one pinball is discharged from one of ball paths 7a, 7b by the one directional action of the rotation control member 13.
