<P>PROBLEM TO BE SOLVED: To provide a method of adjusting the oscillation properties of an ultrasonic oscillator, which is easy to substantially make the other resonance frequencies of two or more oscillations match each other, even after the ultrasonic oscillator is assembled. <P>SOLUTION: A projection 3 for support, which is provided in the position of the node of another oscillation or in the position excluding its nearby position, while being the position of the node of, at least one oscillation or its nearby position from among the nodes of plural kinds of oscillations, is ground. Hereby, the characteristics of the oscillation, which do not have an oscillation node at the position where the projection 3 for support is provided, is adjusted. <P>COPYRIGHT: (C)2008,JPO&INPIT |
