Title: Flux applying method
Inventor: TOYODA AKIHIKO
IPC: G05B11/28
Filed: 1991-05-30
Abstract: PURPOSE:To adjust a flux applying quantity to a base plate easily and with high accuracy by pulse control, comparing with the case of executing analogically a fine adjustment of a needle valve. CONSTITUTION:Based on a base plate signal detected by a photosensor 46, a solenoid valve 45 of a pneumatic duct line 44 is subjected to turn-on/turn-off control by a pulse signal outputted from a pulse controller 47. The solenoid valve 45 operates intermittently an air cylinder 55 in a period of 30msec. The air cylinder 33 opens/closes and operates a needle valve provided in a spray hole of a spray nozzle 22. A flux F supplied to the spray nozzle 22 through a duct line 42 from a flux tank 21 pressurized by a pneumatic source 41 is subjected to pulse atomization intermittently by the air cylinder 33. The flux (f) atomized slenderly in the width direction of a base plate to a printed board P which is being carried moves relatively. By varying a turn-on time in a pulse waveform, flux applying density, that is, flux film thickness is adjusted.

Title: Brushless synchronous motor
Inventor: NANBA MASANAO
IPC: H02K19/12
Filed: 1993-05-31
Abstract: PURPOSE:To provide a synchronous motor with reduced outer dimensions, large capacity and a long life, by using a short-circuit thyristor in a reverse polarity to a three-phase composite bridge made up of a diode as a one-phase bipolar element and thyristors as two-phase bipolar elements, and connecting the short- circuit thyristor with a main field winding in parallel. CONSTITUTION:Short-circuit thyristors 4A and 4B are connected in parallel with a field winding 6A, and a middle part of the thyristors 4A and 4B is connected through a connecting line 5 to a middle part between a gate control circuit 3 and a third phase part of a three-phase all-wave rectifying circuit 2, namely between diodes 2d and 2e. When the thyristor 4A or 4B is caused to ignite in error during the normal operation of the rectifying circuit 2 through noises propagated from the power-supply side of an exciter 1, a reverse voltage is surely applied just after half a frequency cycle of a voltage induced by an armature winding 1B of the exciter 1. Then, the thyristor 4 is turned off and the operation returns to a normal state. Consequently, the outer dimension of the motor is reduced and the capacity and life of the motor are increased.

Abstract: PURPOSE: To securely perform desired clamping, by attching pinch plates with buffers and absorbing the pushing force due to inertial rotation and bringing the pinch plates into pressural contact with the end faces of tranferred article under sufficient pushing force.  
     CONSTITUTION: A motor 27 is driven, a screw shaft 29 is rotated and a pair of right and left trucks 21 are moved toward each other.

Title: Semiconductor light pulse inverter
Inventor: NAKAGOME YUKIO
IPC: H04B10/40
Filed: 1978-10-19
Abstract: PURPOSE:To provide the subject inverter wherein a semiconductor amplifier and semiconductor laser are energized by a current pulse of a clock frequency synchronizing with the light pulse signal thereby to control two modes of oscillation and non-oscillation to obtain light output pulses. CONSTITUTION:A light input signal 5 injected in a semiconductor light amplifier 4 is directly amplified, and a light output signal 6 is obtained. A part 8 of the signal 6 is branched by use of a semi-transparent mirror 7, and converted into an electric signal 10 by use of a photodiode 9. A timing component 12 is extracted from a timing extraction circuit 11, and a driving current pulse 14 is produced by a current pulse generator 13 on the basis of the component 12, the thus produced pulse being applied to the amplifier 4. Since the amplifier 4 is energized by a current pulse having a clock frequency synchronizing with the signal, it acts as an amplifier only at the time when a current pulse is applied thereto, and therefore the width of light pulse is shaped. Oscillation and non-oscillation of a semiconductor laser 33 are controlled by a output light pulse 15, and the amplitude of a light output pulse 32 is shaped.

IPC: H04L13/00
Filed: 1984-06-22
Abstract: PURPOSE:To quicken the communication speed while decreasing deviation of synchronization by correcting a synchronizing timing of serial data at reception through the detection of bit change in asynchronous communication. CONSTITUTION:A timing signal obtained 2 by frequency-division at a counter when no change exists in a serial data bit at reception is given to a terminal RXC' of a communication section 1. Thus, the communication section 1 inputs a serial data of a modulation-demodulation section 3 via a terminal RXD in synchronization with the rising of the timing signal at the terminal. When there is a change in the serial data bit, a detection circuit 7 responds to the change in the bit and generates a one-shot pulse and inputs it to a terminal RD of the counter 6. The counter 6 is reset by a high level of the one-shot pulse of the circuit 7, and when the level goes to low, the frequency division of the clock signal is started again and the timing signal is fed to the terminal RXC' of the communication section 1.
