DEFINITION

Classification: 310/323.01

Direct mechanical coupling:

(under subclass 321) Subject matter in which the resonant structure physically contacts a body on which it performs work, or from which it receives energy.

(1) Note. Examples of subject matter in this subclass include ultrasonic tools, vibrators and atomizers.
