    Abstract: A system is provided for optimizing the output power of an acoustic wavetrain emitted from a transducer rotatably mounted in a downhole borehole televiewer for scanning the sidewall of the borehole. The purpose is to prevent destructive interference between the caudal portion of the outgoing wave train and the returning echo signals from the borehole sidewall.

    Abstract: A transmission circuit transmits an ultrasonic signal from an ultrasonic vibrator by driving a terminal voltage of the ultrasonic vibrator using a first pulse signal and then further driving the terminal voltage using a second pulse signal having an opposite phase to the first pulse signal. At least one of a pulse number of the second pulse signal and a pulse level of the terminal voltage is arbitrarily set.

    Abstract: An illustrative embodiment of the present invention includes acoustic transmitting transducer apparatus for use in well borehole logging which provides a sharper, more intense pulse of acoustic energy than heretofore possible while at the same time eliminating undesirable electric fields in the vicinity of the transducer element. Novel circuit means including remote mounted charge storage means, switching means, voltage transforming means and isolation circuitry together with mechanical end clamping are combined to produce this result.
