Abstract
Abstract An ultrasonic cleaning apparatus including a tank for holding a cleaning solvent therein and vibrating member having at least three sides disposed within the tank wherein each of the three sides is provided with at least one transducer attached thereto in order to provide ultrasonic vibrations within the walls of the three-sided vibrating member. Films, wires, and the like are cleaned by exposing the films, wires and the like to a liquid medium contained within this device utilizing cavitation to clean.
