Method of making a transducer from a boule of lithium tetraborate and transducer so made

摘要

An improved transducer is obtained by providing a plate of lithium tetraborate with a doubly rotated orientation of phi SIMILAR 17 DEG to 21 DEG and theta SIMILAR 54 DEG to 58 DEG where doubly rotated orientations are described by the IEEE notation widely known in the art as (YXwl) phi / theta .
