Title: Control device for on-vehicle motor antenna
Inventor: NAKASE KAZUHIKO
IPC: H02P7/00
Filed: 1986-04-22
Abstract: PURPOSE:To attain automatic control without using a limit switch or the like by interrupting a current when a motor current reaches a prescribed value or over. CONSTITUTION:In applying a power switch of a radio receiver, a voltage is impressed to a terminal RX, and a relay RL1 is excited via a diode D4, then a relay contact point S1 is thrown to the position (a), power is given in a route of +B-contact point S1-terminal m1-motor M and the antenna is extended. When the antenna comes to its extreme and is locked macanically, an overcurrent flows to the motor M, a resistance of a positive characteristic thermister RP2 is increased to turn on a transistor TR2. Then the relay RL2 is excited, a contact point S2 is thrown to a position (a) and the current of motor M is interrupted. Since the control of the motor antenna is applied without using a mechanical limit switch or a clutch, the mechanism is simplified.

Title: Semiconductor relay circuit
Inventor: IITAKA YUKIO
IPC: H03K17/78
Filed: 1986-04-23
Abstract: PURPOSE:To execute a quick switching by connecting the 2nd transistor in parallel with photodiode array and connecting a phototransistor between then so that the 2nd transistor can be turned off at the time of irradiating an optical signal and further connecting a resistance so that the 2nd transistor can be turned on at the time of blocking an optical signal. CONSTITUTION:When an input current flows between input terminals I1 and I2, the gate potential of an output FETQ1 rises thanks to the actions of a light emitting diode L and the photodiode array D, and a phototransistor TrP is turned on. At that time, the resistance R is made significantly great, and a current flowing from the photodiode array D is made minimal. A voltage across the gate and source of the FETQ1 is quickly boosted to speed up turning-on. When the input current between the input terminals I1 and I2 comes to zero, a voltage coexisting across the drain and source of a TrQ2 makes its gate potential at the level the same as the drain potential of the TrQ2 through the resistance R, and the TrQ2 is turned on. The charge fo the output FETQ1 is speedily discnaraged through the TrQ2 to shorten the turning-off time.

Abstract: PURPOSE: To save the consumption of chemicals and enable discoloration of colored waste water at low cost, by treating the dye waste water containing phthalocyanine metal complex by Fenton method, and removing the precipitate of produced special insoluble complex salt.  
     CONSTITUTION: Phthalocyanine dye waste water containing copper, Ni, etc. is treated by Fenton method in a purification tank 1 by adding H 2 O 2  and iron salt (Fe 2+  or Fe 3+ ) according to a known method.

This complex salt is removed in a precipitation tank 5 which is newly installed, and the waste water is sent to a conventional coagulation tank 2, and NaOH is added to adjust pH to about 8 to 10 to promote the growth of flocs. Then, the solid matter is separated again in a precipitation tank 3, and the supernatant is neutralized with  sulfuric acid to pH7, and is discharged. From the coprecipitation of complex salt removed above, Fe 3+  is separated and recovered to be reused. This method, as compared with the conventional method, excels in the discoloration effect and COD  removal effect.

Title: Humidity sensor
Inventor: FUKAMI AKIRA
IPC: G01N27/12
Filed: 1982-06-02
Abstract: PURPOSE:To obtain a humidity sensor with limited variation of resitance value by heating a moisture sensing section produced by manufacturing the mixture of a organic fiber tending to swell by absorbing moisture and a conductive fiber into a paper with a heater. CONSTITUTION:A moisture sensing section 1 comprises a carbon fiber paper made up of a cellulose 1a and a carbon fiber 1b. As the degree of the swelling and the deformation of the cellulose fiber 1a due to moisture absorption depends on the hysteresis of the humidity, the resistance of the humidity sensing section 1 after subjected to an extreme dry condition and a high humidity deviates from the normal resistance value. To prevent this, the moisture sensing section 1 is wrapped with a heater 7 and a timer 9 operates a relay 8 intermittently to apply a power to the heater 7 from a power source 10 so that the moisture sensing section 1 and the ambient air will be dried quickly by heat. Thus, the characteristics of the moisture sensing section 1 can be stabilized to minimize the variation in the resistance value.

The required time for CVD is varied in accordance with the film thickness but normally a deposition rate of 150-250Angstrom /min. is employed. After the predetermined film thickness is obtained, the supply of the reactive gas is discontinued and the substrate is taken out of the CVD apparatus.
