Title: Control device for activity of steel plate surface in continuous annealing
Inventor: YOSHIDA TOSHINORI
IPC: C23C22/00
Filed: 1980-06-23
Abstract: PURPOSE:To obtain steel plate surface of moderate activity through oxidation reaction by controlling the amount of exhaust steam based on the temp. of a steel strip fed into a conduit pipe connecting the cooling zone and quench tank of a continuous annealing furnace and the dew point in  the conduit pipe. CONSTITUTION:At the time when a steel strip 1 past a cooling zone 2 is cooled by a spray header 4 and a quench tank 5, a large amount of steam is produced. While this is ascending in a  conduit pipe 3, part thereof is forcibly exhausted by a blower 6 through a take-out port 7, an  eliminator 11, etc. right after the production, and the rest is allowed to ascend and to contact the  strip 1, so that an oxidized film of target thickness is formed. To this end, whether the amount of  this ascending steam is a target amount or not is detected by a dew point detector 14. Since the  target amount varies with the temps. of the steel strip, said temps. are detected with a thermometer 17. The target dew point value of a dew point recording controller 16 is corrected and set by  the value thereof. The atmospheric gas in the pipe is passed through the detector 14 by a pump  15, and the output thereof is fed to the controller 16, which in turn outputs a control signal in a  manner as to eliminate the deviation with the set target value, thereby controlling an exhaust steam flow rate control valve 9.

Title: Signal generator by light
Inventor: MARUYAMA FUMIO
IPC: H04B10/00
Filed: 1979-07-05
Abstract: PURPOSE:To discriminate easily whether shielding a photodetector from a light emitting element is completed, by using a PLL circuit that is driven by photodetection and then drives the light emitting element. CONSTITUTION:One signal photodetected by photodetector 1 is input to multiplying circuit 2, and the other drives PLL circuit 6 through 90 deg. phase-shifting circuit 5. One output of the PLL circuit is input to multiplying circuit 2 and the other drives light emitting diode 8 through light-source driving circuit 9. Assuming a body to reside between the photodetector and light emitting diode for shielding, no output  signal is sent out because any output of the photodetector does not arrive, but when  no body resides, two signals 90 deg. out of phase with each other are input to multiplying circuit 2, which outputs a low-frequency signal. Then, providing the light source and photodetection part in the loop of the PLL circuit can attain synchronization between the both, so that malfunction caused by disturbing light will not occur.

IPC: G06F9/48
Filed: 1983-05-16
Abstract: PURPOSE:To obtain both functions of advance priority and priority by feeding back the interruption permission signal of the final stage of a priority deciding circuit to the input of the interruption permission signal of the first stage via a switch. CONSTITUTION:Gate circuits 4-1-4-4 form a priority deciding circuit. The interruption permission signal of the final stage 4-4 of the priority deciding circuit is fed back to the first stage 4-1 via a switch 7. When the switch 7 is switched to connect 7-1 and 7-2, for example, 0 is applied to the input of the interruption permission signal of the circuit 4-1 to form the priority deciding circuit for the output of a 0-level generator 6. While the switch 7 is switched so as to connect 7-1 and 7-3, the output of the interruption permission signal of the circuit 4-4 is fed back to the circuit 4-1 to form an advance arrival priority circuit. Thus it is possible to obtain a circuit of simple constitution which serves as two types of circuit.

Title: Photo-arc thyristor
Inventor: HASHIMOTO OSAMU
IPC: H01L29/74
Filed: 1981-06-03
Abstract: PURPOSE:To make a base layer narrower in an element of high dielectric strength and shortening a lag time for arc thereafter, by making a PNIPN structure of four layers for a thyristor. CONSTITUTION:What is different from a conventional thyristor structure is that an N-base layer 2 consists of a low impurity density N(-)-layer 21 and a high impurity density N(+)-layer 22. This thyristor is of PNIPN structure. If voltage is so applied to it that an anode 5 is positive to a cathode 6, a junction between N-layer 2 and P-layer 3 is reverse-biased. A depletion layer in the N-layer 2 extends to th N(+)-layer 22 beyond the N(-)-layer 21 as the voltag goes higer. However, the depletion layer extends in the N(+)-layer 22 less than in the N(-)- layer 21. The whole depletion layer 7 becomes narrow, thus shortening a lag time for arc.
