Abstract

PURPOSE:To obtain the Q value of oscillator subminiature and sufficient, by taking the ratio of the major plane length to the oscillator length as 0.32 to 0.68 and the ratio of the remaining thickness to the major plane thickness as under 0.4. CONSTITUTION:The excitation electrode 9 is provided over the bevel part 10 and the oscillator major plane, and the ratio of the oscillator major plane length 11 to the oscillator length 14 as 0.32 to 0.68 and the ratio of the bevel part remaining thickness 12 to the oscillator major plane thickness 13 as under 0.4.
