Abstract:
An apparatus for measuring the intensity of ultrasonic waves generated by a diaphragm including a plurality of vibrators in a cleaning tank is provided. The apparatus includes a frame having bars corresponding to each side of a hexahedron, and a plurality of aluminum foils spaced a predetermined interval apart from each other and perpendicular to four parallel bars of the frame. The apparatus for measuring the intensity of ultrasonic waves can be used for cleaning a shadow mask during manufacture of a cathode ray tube.
