摘要:
Stress compensated quartz resonators having ultralinear frequency‐temperature responses have been discovered, consisting of doubly rotated cuts whose orientations, defined in terms of the polar angles &fgr; and &thgr;, lie on a locus where the second‐order temperature coefficients of frequency are zero in the range of &fgr;=10 °±2 ° and &thgr;=110 °±5 °. These angles of orientation are in close proximity to, or on the locus of, zero frequency coefficients of stress and are thus referred to as new linear and stress compensated (NLSC) cuts. In the vicinity of the NLSC cuts, a relatively strong 123¯1 x‐ray plane exists at &fgr; equal to 10.9 ° and &thgr; equal to +106.6 °. This x‐ray plane makes the manufacture of NLSC cuts easier and cheaper than ones previously reported. In this paper the theoretical and experimental values of the frequency‐temperature responses and some physical features of NLSC cuts are discussed.
