Abstract

UN CIRCUIT DESTINE A PRODUIRE UNE TENSION DE DENTS DE SCIE COMPORTE UN GENERATEUR DE DENTS DE SCIE DONT LA DUREE EST DETERMINEE PAR LA CAPACITE D'UN CONDENSATEUR, ET LE COURANT DE CHARGE DU CONDENSATEUR LORSQU'UNE SOURCE DE COURANT L'ALIMENTE. UN ETAGE DE COMPTAGE 13 DETERMINE LA DUREE DE LA DENT DE SCIE PRODUITE PAR LE GENERATEUR DE DENTS DE SCIE 11; ET UN PANNEAU DE REGLAGE 17 PERMET DE REGLER LA DUREE DE DENT DE SCIE DESIREE. LE DISPOSITIF COMPORTE DE PLUS UN ETAGE COMPARATEUR 15 DESTINE A FOURNIR UN SIGNAL DE SORTIE QUI DEPEND DE LA DIFFERENCE ENTRE LA DUREE DESIREE DE LA DENT DE SCIE ET LA DUREE DE LA DENT DE SCIE PRODUITE, SIGNAL A L'AIDE DUQUEL LA TENSION EN DENTS DE SCIE PRODUITE PAR LE GENERATEUR DE DENTS DE SCIE EST REGLE SUR LA VALEUR CORRESPONDANT A LA DUREE DESIREE.
