Abstract

L'INVENTION CONCERNE LES RESONATEURS A QUARTZ. LES ELECTRODES 7, 8 QUI SONT FORMEES A LA SURFACE DES BRANCHES D'UN RESONATEUR A QUARTZ DU TYPE DIAPASON SONT DIVISEES EN UNE MOITIE SUPERIEURE 10 ET UNE MOITIE INFERIEURE 11 QUI SONT ATTAQUEES AVEC DES POLARITES OPPOSEES. CETTE CONFIGURATION UTILISE EFFICACEMENT LE CHAMP ELECTRIQUE CREE DANS LE CAS DE L'EXCITATION DU PREMIER PARTIEL D'UNE VIBRATION DE FLEXION. APPLICATION AUX MONTRES A QUARTZ.
