Abstract
Axes X', Y' and Z' of a resonator are established from the axes X, Y and Z of a quartz crystal by virtue of two rotational movements through angles phi and theta , respectively. The resonator is energized to vibrate in accordance with the fundamental torsional mode. The angles of cut phi and theta are such that the first-order temperature coefficient is zero. The torsional mode may be coupled to a flexural mode in order to render the second-order temperature coefficient zero. The fork tines extend in the X' direction. In other embodiments the tines extend in the Y' direction and the rotation phi and theta are about the X and Z' axes, respectively.
