Abstract

The fine adjustment is carried out, in a single operation, of the thermal properties and of the frequency of a quartz resonator comprising a quartz crystal having the shape of a rectangular plate of dimensions: 3.4 x 3.9 x 0.15 mm, provided with electrodes, by adding a 15 microgramme weight (corresponding to 0.3% of the total weight of the resonator) shared out between two point regions located in the middle (A, A') of two opposite sides (a, a') of the plate. There is thus obtained, simultaneously, a variation of the first-order thermal coefficient of -2 x 10<-6>/ DEG C and a relative variation of the frequency of -2.5 x 10<-3>. <IMAGE>
