Abstract

1,034,249. Transistor generating circuits. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. Oct. 21, 1964 [Oct. 24, 1963], No. 42840/64. Heading H3T. A piezo-electric ultrasonic generator or analogous oscillatory device is driven by a transistor working in the avalanche breakdown region. The base of the transistor is earthed, the emitter connected to earth over a resistor 8 (Fig. 2, not shown) and the collector connected to a sufficiently high biasing potential 4 over a further resistor 5, the piezo-electric device 1 being connected between collector and earth. The pulses generated may be rendered of short duration by shunting the piezo-electric device with a damping resistor 11 (Figs. 3, 4, not shown) in series with a capacitor 12 which may be resonated at the working frequency with series inductance 13. The piezo-electric device may also be used for the reception of ultrasonic waves, being connected to an amplifier and output device 14 (Fig. 5, not shown) by a coaxial cable 15 terminated in its characteristic resistance 16. This may constitute the damping resistance, previously referred to: a series capacitor 17 avoids disturbance of the recharging of device 1 over resistor 5. In a modification, the piezo-electric device 1 (Fig. 6, not shown) is connected between the emitter of the transistor and earth, being replaced between collector and earth by a fixed capacitor 18. The base of the transistor is connected to the slider of a potentiometer from earth to a point of negative potential, while the terminating resistor can in this arrangement be connected directly across the cable.
