摘要： The resonator obtained by this process comprises an active central portion, the thickness of which is reduced until the desired frequency is obtained. This may be of the order of 50 to 100 MHz. This central portion is surrounded by a considerably thicker reinforcing frame to which it is mechanically connected by means of one or more connecting members which are thinner than the active portion. The connecting member or members eliminate the need for coupling between the reinforcing frame and the active portion. Electrodes are provided for exciting the resonator.

摘要： The invention concerns a transducer for measuring an angular velocity formed by a single piezoelectric tuning fork (21) that rotates at said angular velocity. The tuning fork includes two vibrating legs(23, 24) extending from a base (22), means (25a, 25b, 26a, 26b) exciting a first vibration of the tuning fork, arranged on the excitation leg (23), and means (27a, 27b, 28a, 28b) detecting a second vibration of the tuning fork generated in response to the first vibration and to a rotation of the tuning fork, arranged on the detection leg (24). The detection leg has a cross-shaped section including two top lateral faces (33, 34) and two bottom lateral faces (37, 38), separated by protruding parts (41, 42) projecting with respect to said faces. The detection means include first (27a) and second (28a) detection electrodes arranged facing each other, each being arranged on one of the top lateral faces (33, 34), such that the electrical field between the first and second detection electrodes is substantially rectilinear through the detection leg, and third (27b) and fourth (28b) detection electrodes arranged facing each other, each being arranged on one of the bottom lateral faces (37, 38), such that the electrical field between the third and fourth detection electrodes is substantially rectilinear through the detection leg.

摘要： A resonator has a parallelepipedal bar of a piezoelectric material designed to vibrate in an extension mode, and suspension means of said bar which form a single, integral part with the latter and which are only connected to one of its lateral faces. This arrangement makes it possible to reduce the number of parasitic vibration modes which could couple to the main mode as well as coupling between these modes, and hence variations as a function of the temperature in the characteristics of the resonator, notably in its quality factor.
