Title: Power supply circuit
Inventor: MIYAMOTO JIYUNICHI
IPC: G05F1/56
Filed: 1981-07-15
Abstract: PURPOSE:To improve the efficiency of power supply at low voltage, by controlling forward and reverse bias to a power supply circuit at high and low voltages respectively and setting the respective output states. CONSTITUTION:When a power supply potential Vcc is low and a Zener diode ZD is nonconductive, a transistor (TR)Q5 is turned off, a TRQ4 turns on and the base of TRs Q2 and Q3 is grounded. Thus, the TRQ2 is turned off and the TRQ3 is turned on, and a current supplied from a power supply circuit can be controlled with a resistor R4. When the power supply Vcc is high and the diode ZD is conductive, the TRQ3 is turned off and the base current to the TRQ1 is supplied from the power supply Vcc via a resistor R2.

IPC: B21D9/01
Filed: 1982-06-30
Abstract: PURPOSE:To remove easily a recess generated in the inside of the bent surface of a square pipe, and to improve operation efficiency, by bending the square pipe into which a plate spring jig is inserted, into a prescribed curved surface by supporting the pipe by a pair of fulcrums placed at the outside of the sliding locus of a punch, and then pressing the pipe by supporting it by a small bearing surface. CONSTITUTION:A square pipe (a) into which a plate spring jig (b) is inserted is fitted to a groove 5a in the bearing surface 5b of bearing seats 5, 5, and then a punch 3 is lowered. The pipe (a) is bent by the curved surface 3b of the punch 3 while being restricted by the groove 3a of the punch 3. At that time, the seats 5, 5 are bent around their fulcrums 7, 7 by the lowering of the divided surface of the seats 5, 5 against elastic members 9, 9. Then, a recessed part C is formed at the bent part of the inside of the pipe (a) by said bending. But when the punch 3 is further lowered, the recessed part C is flattened along a curved surface 3b because the pipe (a) is supported at the outside of its bent part and is pushed up by a correcting block 6.

Title: Channel retrieving method of personal radio equipment
Inventor: ARAI TAKAYUKI
IPC: H04B1/40
Filed: 1984-05-31
Abstract: PURPOSE:To retrieve a channel where a disturbing radio wave is small by switching a free channel detection level stepwise from a low level to a high level with a switching control signal and retrieving a free channel. CONSTITUTION:For example, a station A retrieves a free channel while stations B and C has a mutual communication and the station C is in transmission. In this case, when a changeover switch circuit 22 is operated to the side of a low- level semifixed resistance 23 with the switching control signal X, an electric field area becomes wide as shown by L in a figure. It is therefore evident that the communication with the station C is impossible, and the retrieval moves to a next channel and thus makes one round while the level is held low, retrieving a free channel. The figure shows that a station D is retrieved as the free channel. If no free channel is found even after one round, the circuit 22 is switched to the side of a high-level semifixed resistance 24 with the switching control signal X, and then the electric field area becomes narrow as shown by H. A this time, the stations C and D can not have a communication during low-level retrieval, but are allowed to perform transmission as a free channel when the level is high.

IPC: H01L21/768
Filed: 1984-05-31
Abstract: PURPOSE:To eliminate surface irregularity after the formation of a pattern and to prevent the breakdown of wire when an aluminum pattern is formed, by manufacturing a semiconductor in consideration of the fact that the thickness of an oxide film becomes twice when polysilicon is oxidized. CONSTITUTION:Poly Si 13 [its thickness is (t)] is formed on the entire surface of a substrate 11. The poly Si 13, which is not coated by resist 14, is etched by about 1/3 the entire thickness. Doping is not performed at a part, which requires the pattern of the poly Si 13. Only the other part is doped. Thus difference in impurity concentration is provided. When the poly Si is oxidized, the thickness of the oxide film becomes twice. The thickness of an oxide film 15 at a part, where the poly Si with a thickness of 2/3t is oxidized, becomes 4/3t. Thus the surface is flattened. Then patterning of an Al wiring 17 is performed. In this way, the breakdown of the wire can be perfectly prevented.
