Abstract

RESONATEUR PIEZOELECTRIQUE A DIAPASON DE PETITES DIMENSIONS ET COMPORTANT LE MINIMUM D'ELEMENTS DISTINCTS SEPARES. L'ELEMENT RESONNANT 1 ET SON SUPPORT 2 SONT DECOUPES 3 POUR CONSTITUER UNE SEULE PIECE DANS UNE PLAQUETTE DONT LA PARTIE CENTRALE FORME LE DIAPASON 1 ET LA PARTIE PERIPHERIQUE UN CADRE-SUPPORT 2. LES DEUX PARTIES RESTENT RELIEES ENTRE ELLES PAR LA BASE DU DIAPASON. DES COUVERCLES 8 PLANS OU EN FORME DE CUVETTES PLATES SONT FIXES 7, 9 SUR LE CADRE 2. L'INVENTION PEUT S'APPLIQUER CHAQUE FOIS QU'IL EST NECESSAIRE DE DISPOSER D'UN RESONATEUR A DIAPASON D'ENCOMBREMENT EXTREMEMENT FAIBLE.
