Abstract

The quartz-crystal resonator has its frequency adjusted by altering its mass in at least one region having a small area compared to the total surface of the resonator. The region altered may lie at the edge of the resonator or close to it such that the temp. coefficient of the resonator's resonant frequency is changed without altering the dimensions of the resonator. Adjustment of the resonator takes place in two stages. First the resonator's mass is altered such that the temp. coefficient of the first order of the resonant frequency is zero. Then the mass is altered in a different place such that the resonant frequency is altered but not the thermal properties of the resonator.
