Title: Simplex radio communication system
Inventor: SHIMODA TAKESHI
IPC: H04B1/40
Filed: 1979-06-08
Abstract: PURPOSE:To enable transfer of needed information as well as an interruption of emergency communication from a subordinate station, by allowing the subordinate station to perform blocking release by itself automatically after a certain time in a selective signal system. CONSTITUTION:Between master station 1 and subordinate stations 2-N, mutual communication comes into effect at frequency f1. In this case, a selective signal sent out from master station 1 is input to deciding circuit 12 of each subordinate station and when the selective signal of the station is decided, latch circuit 14 is driven by output Y. Then, a ready-for-communication state is displayed 16 and radio transmitter controller 18 is driven by operating press button 17, so that transmission will be possible. On the other hand, when the selective signal is not addressed to the station, display unit 16 displays the ready-for-communication state by output N and gate 15 is turned OFF. Further, clock 22 is counted 20 by output N and circuit 14 is driven by an output of a fixed count value to turn gate 15 ON.

Title: Noise reducing circuit
Inventor: OOYAMA MASAO
IPC: G11B20/04
Filed: 1980-05-28
Abstract: PURPOSE:To prevent an adjustment error by providing an arithmetic circuit between a level sensor output amplifying circuit and an arithmetic circuit which applies a control voltage to a voltage-controlled amplifier. CONSTITUTION:An amplifier 11 multiplies an input signal applied to an input terminal IN by a prescribed number, and a limiter circuit 20 composed of transistor TRs Q1 and Q2, a resistance R20 and variable resistor VR1 limits the output voltage of the amplifying circuit 11 to a prescribed value. An arithmetic circuit 21 is composed of an operational amplifier OP3, resistances R21-R24, and a variable resistor VR2 and lowers the amplification degree of the circuit 11 by ten percent. Then, the resistance VR2 offsets a voltage at the input point A of an arithmetic circuit 22. Adjustment points are decreased in number in comparison with the offsetting of different variable resistors for encoding and decoding, and correct arithmetic is performed without the approximate correction of the resistance R23 at a noninverted + input terminal by the circuit 22, thereby preventing an adjustment error.

Inventor: NAKAZAWA KOUJI
IPC: G11B21/24
Filed: 1982-04-30
Abstract: PURPOSE:To correct an error of pyramid at the tip of a stylus with high accuracy while assembling the stylus to a cartridge regardless of the said error, by deforming a member holding the stylus tip. CONSTITUTION:When the stylus tip 1 is polished into a pyramid and there exists some rror at an angle between a plane A being the reference plane and a ridge line BC, the error is observed that the ridge line BC is titled to the normal of the plane A viewed from just under. The view from the arrow D is shown in solid lines (n) Figure. In deforming a holder 8 shown in solid lines with a torsion toward left direction by phi as shown in Figure as an imaginary line, the cross angle between the normal of the plane A and the ridge line BC is changed in viewing it beneath. In giving a torsion to the holder 8 so as to obtain the torsional angle phi as phi=epsilon0/tanalpha, where epsilon0 is the tilt angle, alpha is the cross angle after torsion, and epsilonm is an angle between the normal of the plane A and the ridge line BC, the cross angle epsilonm is almost zero and the projection of the line BC is a right angle to the plane A with high accuracy.

Title: Electro-magnetic flow meter
Inventor: AKIYAMA HITOSHI
IPC: G01F1/60
Filed: 1981-05-14
Abstract: PURPOSE:To remove noise comonents by combining in a specified order two pause periods of equal time length and two exciting periods, and adding successive samples taken in an even number and multiplying a coefficient to this addition after commercial frequency noises are removed and carrying out calculation. CONSTITUTION:An exciting coil 1 is excited by the signal 13 of a calculation control unit 7 and a positive exciting period A, a negative exciting period B, pause periods C and D are of equal length. Electrodes 3a and 3b are connected to a differential amplitude 6 through buffer amplifiers 4 and 5. The output of the amplifier 6 is given to sample-hold circuits 8 and 9 via a switch SW3. Two samplings at every A-D period are carried out by means of SW3. With this arrangement commercial frequency noises are removed and the output of an amplifier 10 is given to a calculation circuit 11, where sample values are multiplied by coefficients to output flow rate signal 16. Values of said coefficients are set, so that they can offset electro-chemical direct current noises and electro- magnetic noises.

Title: Control device for internal-combustion engine
Inventor: MORITA TATSURO
IPC: F02P5/15
Filed: 1985-04-04
Abstract: PURPOSE:To enhance the operability by interrupting the correction control of ignition timing due to the position of crank angle during the transient period after the load change of an engine has exceeded a prescribed value and carrying out the correction control of air-fuel ratio so that the position of crank angle may coincide with a target value. CONSTITUTION:When the air-fuel ratio is lean, the combustion speed becomes slow and thetapmax (the position of crank angle in which the pressure in the cylinder is maximum) becomes large, and on the contrary, when this is rich, thetapmax becomes small. Now, when the load change exceeding a prescribed value occurs, the prescribed period during which the change is anticipated to continue starting from the beginning is made a transient period. And during the time the correction control of ignition timing by an ignition timing control means C is interrupted, and the correction control of air-fuel ratio by an air-fuel ratio correction means F is carried out. By this means thetapmax is made to coincide with a target value thetapmaxo. Thus, the variation of air-fuel ratio during a transient period can be reduced, and consequently the torque fluctuation can be reduced.

Abstract: PURPOSE:To uniformalize developing action covering the whole article to be developed while attaining equalization covering the whole article to be developed during a developing process and between articles to be developed by controlling the temperatures of a plate heater heating the articles to be developed and a developer. CONSTITUTION:The coated surface of a wafer 1 coated with photosensitive polyimide 2 is directed upward, and the wafer 1 is held horizontally under the state in which it is floated onto a plate heater 3 by a quartz pin 9 group. A controller 7 adjusts a heater 5 by a thermocouple 6, and controls the heater 3 so as to be kept constant at the set temperature of the wafer 1. A developer 11 is controlled in a fixed quantity by a liquid-run preventive device 15, and dripped onto photosensitive polyimide 2 spread onto the wafer 1. The temperature of the developer 11 is adjusted so as to be kept constant at a preset temperature by a temperature regulator 16 controlled by a controller 17. Consequently, when the developer 11 is dripped to photosensitive polyimide 2 on the wafer 1, it is diffused uniformly by surface tension thereof. The developer 11 is controlled at a fixed temperature at that time, and the wafer 1 is controlled at a fixed temperature, thus equalizing development covering the whole. Accordingly, an exposure pattern is processed accurately.
