8D-2 Vibration Characteristics of Complex Vibration Converters Using Different Velocity Metal Ring Pairs

Longitudinal to transverse vibration converters using different velocity metal-ring-pair with slanted thickness are proposed. Using the metal-ring-pair, complex vibration with no normal vibration component is obtained which is adequate for ultrasonic welding of semiconductor flip-tip bonding with large number of bonding pads, and also welding of large area specimens. And also, ultrasonic motor and rotating complex vibration machining tool are obtained using two metal-ring-pairs installed in a right angle.
