Title: Constant-voltage inverter device
Inventor: KOYAMA SHIGERU
IPC: H02M7/48
Filed: 1978-04-13
Abstract: PURPOSE: To efficiently obtain constant-voltage output to the sharp fluctuation of input voltage, by controlling an inverter circuit using a saturable core by controlling a gate pulse generating circuit by means of a constant-frequency pulse generating circuit.  
     CONSTITUTION: A constant-frequency pulse generating circuit 5 generates short pulses with a fixed period, the pulses are afforded to the bases of the transistors TR5, TR6 of a gate pulse generating circuit 6 and pulses from pulse transformers GT 1 , GT 2  operate the transistors TR1, TR2 and thyristors TH1, TH2 of an inverter circuit 4. Thus, constant output voltage can continually be obtained regardless of the fluctuation of input direct current voltage by keeping the timing of the ignition of the thyristors at a suitable constant period because the output wave-forms of an output transformer T using a saturable core are changed into rectangular waves that a quiescent period is formed during positive and negative cycles, by the function of the thyristors TH1, TH2.

Title: Control circuit for electromagnetic coupling device
Inventor: ARAI SHIGEHARU
IPC: F16D65/18
Filed: 1984-03-09
Abstract: PURPOSE:To prevent the occurrence of frictional sound and coupling delay by constituting a control circuit such that exciting power is sequentially increased from low to the highest power according to the operation of a switch to improve damping connection. CONSTITUTION:A drive circuit is provided with a timer TIM, an oscillator OSC and a drive circuit DR. The timer TIM starts according to the operation of a switch SW while the oscillator OSC starts to send the pulselike oscillating output so that intermittent current is supplied to an exciting winding L in an electromagnetic coupling device by the drive circuit DR to restrain the exciting power to low voltage. When the time set by the timer TIM is up, the pulse oscillating power from the oscillator OSC is stopped and current is supplied continuously to the electromagnetic winding L by the drive circuit DR to maximize the exciting power. Thus, under the initial adsorbing condition of an armature, an adsorbing force is low and smooth slip is obtained so that the occurrence of frictional sound is blocked and complete adsorption is obtained according to the increase of the exciting power to permit satisfactory damping coupling.
