Abstract: An ultrasonic transducer employs a ceramic disc which, when excited by a d-c pulse, vibrates in its planar resonant frequency mode. The sensitivity is selectively increased for the second positive half cycle of the transient oscillation of the disc and a method is described for using the selectively improved transient response to greatly increase the precision of measurement of the time interval for a transient pulse of ultrasonic energy to travel the distance between an ultrasonic transmitter and an ultrasonic receiver.

Abstract: The invention describes a novel design of an acoustic transformer which serves as an impedance matching device between the transducer material and the atmosphere. The transformer serves also to effectively increase the limited maximum permissible amplitude of vibration of the transducer material whereby the maximum acoustic power radiated into the atmosphere is substantially increased. The novel acoustic transformer design also results in a significant reduction in the magnitude of the secondary lobes in the directional pattern thereby additionally improving the performance characteristics of the transducer.

Abstract: A semiconductor device includes a driving circuit arranged to be capable of supplying a drive signal in an ultrasonic band to a piezoelectric element, a damping circuit having a resistance load and an inductive load, and a control circuit arranged to be capable of controlling the driving circuit and performing a reverberation reduction operation after stopping the supply of the drive signal to the piezoelectric element. In the reverberation reduction operation, the control circuit controls the driving circuit to supply the piezoelectric element with a damping signal having a phase different from that of the drive signal, and then enables the damping circuit to connect to the piezoelectric element.
