Abstract

L'INVENTION CONCERNE LES OSCILLATEURS A CRISTAL. L'OSCILLATEUR COMPORTE, OUTRE UN CIRCUIT ELECTRONIQUE, UN CRISTAL (QUARTZ), UN PREMIER VARACTOR ET UN RESEAU DE COMPENSATION, UN SECOND VARACTOR, EN PARALLELE SUR LE PREMIER VARACTOR, ALIMENTE A TRAVERS UN POTENTIOMETRE. LE PREMIER VARACTOR A UNE BORNE RELIEE AU CURSEUR D'UN POTENTIOMETRE ALIMENTE PAR UNE SOURCE CONTINUE, LE POTENTIOMETRE SERVANT AU REGLAGE DE LA FREQUENCE. LE RESEAU DE COMPENSATION EST DETERMINE EN FONCTION D'UNE CARACTERISTIQUE TYPE "VARIATION DE LA TENSION APPLIQUEE AU PREMIER VARACTOR EN FONCTION DE LA TEMPERATURE", REPRESENTATIVE D'UNE FABRICATION DE SERIE, ET EST LE MEME POUR TOUS LES OSCILLATEURS DE LA SERIE. LE REGLAGE DE L'OSCILLATEUR SE FAIT A L'AIDE DU SECOND VARACTOR POUR FAIRE COINCIDER LA CARACTERISTIQUE DE L'OSCILLATEUR AVEC LA CARACTERISTIQUE TYPE. APPLICATION AUX OSCILLATEURS COMPENSES EN TEMPERATURE.
