Beveled, coupled mode piezo-electric resonator |
| 摘要 |
A yzw 35 DEG 0' thickness shear crystal bar is provided with bevels cut in its longest narrow surfaces (b, c) proximate the ends in order to obtain energy trapping of the coupled mode vibrations which may arrive at said ends and thus permit shortening of the bar for a given quality factor.
