Multi-coordinate piezoelectric drive for ultrasonic motor, has rotatable symmetric dome portion that is held in close proximity with base surface, and its tip performs multi-dimensional movement

摘要

A rotatable symmetric dome portion in the form of sphere, ellipsoid, paraboloid, cone, and bell rotates the output of the multi-coordinate drive. The rotatable symmetric dome portion is held in close proximity with a base surface, and the tip of the symmetric dome portion performs multi-dimensional movement. The rotatable symmetric dome portion is made of non-electroactive material.
