Temperature-compensated resonator of the primary factor and the secondary factor

摘要

PROBLEM TO BE SOLVED: To provide a first and second order temperature-compensated quartz resonator.;SOLUTION: The core of the bodies 3, 5, 7 of a temperature-compensated resonator is formed from a plate formed at a cut angle (θ') in a quartz crystal determining first and second order temperature coefficients (α, β, α', β'). The bodies 3, 5, 7 include a coating deposited at least partially on the core and having first and second order Young's modulus variations (CTE1, CTE2, CTE1', CTE2') according to temperature of opposite signs respectively to the first and second order temperature coefficients (α, β, α', β') of the resonator so as to render the first and second order temperature coefficients substantially zero.;COPYRIGHT: (C)2012,JPO&INPIT
