Title: Semiconductor device and manufacture thereof
Inventor: NAKAMURA TOORU
IPC: H01L29/73
Filed: 1983-11-28
Abstract: PURPOSE:To obtain a semiconductor device having a small amount of damage effects owing to radiation by forming an emitter region and a collector region via a base region on a surface region of a semiconductor substrate in the surface direction and forming a silicon oxide film having a special thickness on the base region. CONSTITUTION:An N type epitaxial layer 5-2 is formed on an N type embedded layer 5-1 and the surface of the layer 5-2 is oxidized uniformly to form an oxide film having its thickness below 130Angstrom . Next, a silicon nitride film 5-8 is built up to be subjected to patterning by photoetching. This process is carried out by dry- etching an Si3N4 film by use of CH2F2 or CH2F gas using a photoresist film as a mask. Next, when the epitaxial layer is subjected to selective oxidation, an oxide film 5-3 for separation is formed at a region where the silicon nitride film 5-8 is not formed. Hereinafter, one portion of the silicon nitride film 5-8 is subjected to patterning to diffuse P type impurities and form an emitter region 5-4 and a collector region 5-5. After this, electrodes are set to obtain a lateral bipolar transistor.

The universal counter 43 integrates these output pulses for 30 seconds and outputs the result thereof to the interface board 22 of a personal computer 2. The regenerative signal frequency after the inspection is checked in the final.

IPC: H05K1/14
Filed: 1989-08-31
Abstract: PURPOSE:To arbitrarily set a distance between two print boards by forming a thread hole in one of connectors while a thread ridge in the guide pin of the other connector, screwing the thread ridge in the thread hole, and rotating the guide pin to adjust the longitudinal projection of the guide pin. CONSTITUTION:A thread hole 4 is formed in one of connectors 1, 6 engaged with each other; a thread ridge is formed in the guide pin 5 of the other connector. The thread ridge is screwed in the thread hole 4, and the longitudinal projection of the guide pin 5 is adjusted by rotating the guide pin 5. In the case where the projection is smaller than the depth of the recessed hole of the other connector, a distance between print boards 11 and 12 is determined by the abutment on the opposite surfaces of the connectors. Meanwhile, in the case where the projection is large than the depth of the recessed hole 10 of the other connector, the tip end of the guide pin 5 abuts against the bottom of the recessed hole 10, thereby enlarging the distance between the print boards 11 and 12. Therefore, the distance between the print boards 11 and 12 can be arbitrarily set.

Title: Ptc element
Inventor: MORI SADAJIRO
IPC: H01C7/02
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To make it possible to apply a large load current by a method wherein a metallic film is formed on both surfaces of a PTC polymer layer in advance, and an electrode layer is welded on the above-mentioned metallic film. SOLUTION: A metallic film 3, having the electric resistivity higher than the electric resistivity of a PTC polymer layer 1, is formed on the surface of the PTC polymer layer 1, and the PTC polymer layer 1, on which the metallic film 3 is formed, is welded to a metallic layer 2. Consequently, as metal is contained in the layer (metallic film 3) where the PTC polymer layer 1 comes in contact with the electrode layer 2, the composite resistance between the upper and the lower electrode layers, which sandwich the PTC polymer layer 1, can decrease. As a result, a large load current can be allowed to flow continuously.

Abstract: PROBLEM TO BE SOLVED: To increase the fun and interest of a game by a method wherein a plurality of variable prize ports are opened while a sequence pattern and a time pattern are being related with each other. SOLUTION: When a hit ball which is shot on a game panel enters either one of starting prize ports 7a-7c, a detection switch detects the prize ball, and transmits a signal to a circuit board and numerals are changed and displayed by operating a segment display unit 61. Then, when the numerals on the segment display unit 61 indicate numerals which are set in advance, a signal in response to the numerals is transmitted to a driving control circuit, and a plurality of variable prize ports 5a-5e which are made a group, are converted to an opened state wherein the hit ball is more easily received by various kinds of patterns.  For example, when a numeral of (7) is displayed on the segment display unit 61, all the variable prize ports 5a-5e are placed under an opened state for 6 seconds, and a numeral of (.5) or (3) is displayed, the group of the variable prize ports 5a-5e are opened for 1 second each in order from the right or the left.
