ULTRASONIC INDUCTION APPARATUS AND METHOD Apparatus and method for inducing ultrasonic vibrations for use in an ultrasonic process, illustrated in the form of an ultrasonic cleaning process wherein ultrasonic vibrations are induced in a cleaning fluid in contact with an object to be cleaned for cleaning the object ultrasonically, utilize a sealed chamber within which ultrasonic fluid is confined separate from the cleaning fluid and isolated from the atmosphere, ultrasonic transducers associated with the sealed chamber for inducing ultrasonic vibrations in the ultrasonic fluid, and a coupling arrangement by which the vibrating ultrasonic fluid in the chamber is coupled with the cleaning fluid to induce ultrasonic vibrations in the cleaning fluid to accomplish the desired ultrasonic cleaning.
