Title: Motor control circuit
Inventor: OTANI KIYOSHI
IPC: H02P7/288
Filed: 1986-05-22
Abstract: PURPOSE:To enable a controlled motor to be quickly stopped, by interrupting reference voltage to the input terminal of an operational amplifier circuit to stop rotation, and by feeding only counter-electromotive voltage generated on the controlled motor. CONSTITUTION:A bridge circuit is composed of a DC motor 2 and resistances R1-R3, and the detection voltage at detection terminals 7, 8 is fed to an operational amplifier circuit 3. The operational amplifier circuit 3 supplies the driving transistors 12 and 13 with a positive or negative output voltage depending on the detection voltage and the reference voltage. In order to stop the DC motor 2, change-over switches 10, 11 is changed at a neutral position, and the application of the reference voltage is interrupted. As a result, the operational amplifier circuit 3 is worked so that the counter-electromotive voltage of the DC motor 2 may come to zero, and the DC motor 2 is suddenly stopped. When the DC motor 2 is stopped, then a switch circuit 16 is turned ON.

Title: Pulse compression radar
Inventor: NISHIMOTO SHINKICHI
IPC: G01S13/28
Filed: 1984-06-11
Abstract: PURPOSE:To reduce mutual interference under a simultaneous operation by transmitting a signal in a desired binary random number code system of irrelevant 1 and -1 with a phase modulation to suppress a time side-lobe by a coherent integration through a pulse compression with a compression filter. CONSTITUTION:A COHO signal of a COHO oscillator 13 is subjected to a phase modulation at 0 deg. or 180 deg. with a phase modulator 14 by a binary random number system signals 1 and -1 from a random number generator section 11. A weight computing section 12 calculates the optimum weighting factor to be sent to pulse compression sections 41 and 42 and video signals of I and Q channels enter the compression sections 41 and 42 composing respective pulse compression filters to perform a pulse compression. Then, the output following the pulse compression is subjected to a coherent integration over a plurality of pulses in terms of the same range pin to suppress the time side-lobe. This can reduce misrecognition of distance to reduce mutual interferences among a number of radars while eliminating intentional jamming.

Title: Thermal printer
Inventor: MAEZAWA TADAHIKO
IPC: B41J2/36
Filed: 1981-07-30
Abstract: PURPOSE:To obtain sufficient printing density immediately after a power source is turned On, in the thermal printer wherein a supplied power is controlled and the coloring density is made even, by increasing the supplied power by a specified amount until the specified amount of printing is performed after the power source is turned ON. CONSTITUTION:When a turn ON signal (a) is generated by the turning ON of the power source, a flip flop FF1 is set and an analog switch S is turned OFF. Therefore, an output voltage (c) of a three terminal regulator (REG)2 becomes a high level. Currents, which flow through elements that are selected by transistors Q1-Qn in heating elements r1-rn, and Qm become relatively large. When the specified amount of the printing has finished and the base temperature of a thermal head 4 becomes sufficiently high, the FF1 is reset by the trailing edge of a printable signal (d) and the switch S is turned ON. Thereafter the output voltage (c) of the REG2 becomes a low level, and a relatively small current is flowed through the heating resistor elements.

Abstract: PURPOSE:To rapidly avoid the danger of wheel locking and also avoid shortage in braking forces due to subsequent excessive pressure reduction by providing in an air pressure reducing passage a pressure reduction rate regulating means for controlling the quantity of air allowed to pass through the passage. CONSTITUTION:If wheels are in danger of being locked, a hold valve 29 is closed and a decay valve 31 is opened and air pressure within an air chamber 23 is released to atmosphere and a control piston 24 is shifted to the right in Figure. During this initial period, an air pressure reducing passage 22 is broadened by a throttle piston 36 and the air pressure within the air chamber 23 is sharply reduced and a cut valve 21 is rapidly closed. At the same time the capacity of a hydraulic pressure control chamber 25 is enlarged by movement of the control piston 24 and a hydraulic fluid in a wheel cylinder 8 is absorbed and brake fluid pressure is reduced so that locking of the wheels is avoided. Thereafter, the air pressure within the air chamber 23 is lowered and the throttle piston 36 is shifted to the left in Figure by a spring 21 so that the air pressure reducing passage 22 is narrowed.
