Abstract

RESONATEUR EN QUARTZ PIEZOELECTRIQUE, FORME PAR UN CORPS PARALLELEPIPEDIQUE OBLONG DECOUPE DANS UN CRISTAL SUIVANT UNE COUPE AT ET AYANT SON AXE LONGITUDINAL DANS LA DIRECTION Z POUR FAIRE VIBRER LE CRISTAL DANS LE MODE DESIRE, CHAQUE FACE PRINCIPALE PORTE UNE ELECTRODE, LES DEUX ELECTRODES ETANT SITUEES EN REGARD. UNE DES EXTREMITES DU CORPS OBLONG SERT A LA FIXATION DU RESONATEUR SUR UN SUPPORT. L'AUTRE EXTREMITE DU CORPS COINCIDE AVEC LE BORD DE LA ZONE D'ELECTRODES. APPLICATION AUX HORLOGES ELECTRONIQUES.PIEZOELECTRIC QUARTZ RESONATOR, SHAPED BY AN OBLONG PARALLELEPIPEDIC BODY CUT INTO A CRYSTAL FOLLOWING AN AT CUT AND HAVING ITS LONGITUDINAL AXIS IN THE Z DIRECTION TO VIBRATE THE CRYSTAL IN THE DESIRED MODE, EACH MAIN FACE CARRYING THE SITRODEES IN LOOK. ONE OF THE ENDS OF THE OBLONG BODY IS USED FOR FIXING THE RESONATOR ON A SUPPORT. THE OTHER END OF THE BODY CORNER WITH THE EDGE OF THE ELECTRODE AREA. APPLICATION TO ELECTRONIC CLOCKS.
