Abstract

PROCEDE POUR FAIRE VARIER LA CAPACITE D'UN CONDENSATEUR CERAMIQUE. ON FAIT VARIER LA CAPACITE PAR MODIFICATION MECANIQUE DE LA SURFACE ACTIVE D'UNE SEULE DES DEUX ELECTRODES DU CONDENSATEUR CERAMIQUE, PAR UN PROCEDE TEL QUE SABLAGE, RAYONNEMENT LASER, OU L'ANALOGUE, PAR L'INTERRUPTION D'UN OU DE PLUSIEURS ELEMENTS DE PEIGNE, OU DE LA BRANCHE PRINCIPALE DE LA STRUCTURE EN FORME DE PEIGNE ENTRE UN OU PLUSIEURS ELEMENTS DISPOSES L'UNE A COTE DE L'AUTRE. APPLICATION A L'EQUILIBRAGE DE LA FREQUENCE D'UN CIRCUIT OSCILLANT.
