Title: Driving circuit for electromagnetic working equipment
Inventor: YAKURA TOSHIAKI
IPC: G05B11/26
Filed: 1981-02-03
Abstract: PURPOSE:To control the current of a solenoid valve, by comparing a value, which is obtained by comparing and integrating a voltage corresponding to the current supplied to an electromagnetic working equipment and a control input voltage which controls the opening of the solenoid valve, and a triangular wave oscillation output with each other to output a turn-on/off signal. CONSTITUTION:When a signal Vd of an output terminal (d) of a comparator 222 is high-level, a transistor TR226 becomes conductive, and a current is supplied to a coil 213 of a solenoid valve, and a voltage Ve between both terminals of a current detecting resistance 211 becomes as shown in figure. The voltage Ve is amplified by an operational amplifier 228 and becomes a voltage Vf in figure at an output terminal (f). When a voltage Va of a control input terminal (a) is changed as shown by the dotted line in figure 3, an integrator 227 integrates the voltage Va in a proportion in accordance with the deviation of the voltage Va from the voltage Vf to output a voltage signal Vb shown in figure to an output terminal (b). A triangular wave oscillator 230 outputs a triangular wave Vc to an output terminal (c). The comparator 222 compares the output Vb with the output Vc to switch the TR226, thus controlling the current of the coil 213.

Abstract: PURPOSE:To prevent a battery from being consumed by stopping automatically the charging of a main capacitor when it is charged up to a specific value, and inhibiting shutter operation or outputting a flash disabling signal a specific time after the charging stop point of time. CONSTITUTION:An SW1 is turned on to generate a pulse through a capacitor 2 and a resistance 3 and the pulse is shaped 4; and a transistor (TR)5 is turned on to allow a boosting circuit 40 to oscillate. When the terminal voltage of the main capacitor 6 rises to the specific value, a neon tube 7 turns on, and when the voltage further rises, the current of the high-voltage side coil of an oscillation transformer 11 decreases and the base potential of a TR12 rises to make the switch turn off to stop the oscillation. The neon tube 7 turns off, reset terminals of a counter 8 and an FF9 go down to a level L, and the counter 8 begins to count the clock of an oscillator 10. When its counted value attains to a predicted value, the counter 8 generates an H-level output and an OR gate 26 and the FF9 also generate an H-level output, so that the shutter can not be released in this state. The shutter button is returned to restart charging the capacitor. Consequently, the battery is prevented from being consumed and a shutter chance is prevented from being missed.
