Abstract

CIRCUIT POUR COMMANDER ET PROTEGER LE TRANSISTOR DE SORTIE 32 DE DEVIATION HORIZONTALE D'UN AFFICHAGE PAR ANALYSE ACCORDEE DE LA TRAME. LE TRANSISTOR DE SORTIE 32 EST MIS EN CIRCUIT PAR UN COURANT DE BASE DE SENS CONDUCTEUR DETERMINE PAR LES CONDITIONS B, ET HORS CIRCUIT PAR UN COURANT DE BASE DE SENS INVERSE, EGAL A LA MOITIE DU COURANT DE COLLECTEUR DE SENS CONDUCTEUR. ON UTILISE DEUX TRANSISTORS DARLINGTON 55 ET 60 POUR CETTE MISE RESPECTIVEMENT EN CIRCUIT ET HORS CIRCUIT DU TRANSISTOR DE SORTIE 32 EN FONCTION DE L'IMPULSION DE COMMANDE HORIZONTALE, ET ON UTILISE UNE BASCULE MONOSTABLE 54 POUR CONTROLER LA DUREE MAXIMALE DE MISE EN CIRCUIT DU TRANSISTOR DE SORTIE 32. -APPLICATION AUX RECEPTEURS DE TELEVISION ET AUX APPAREILS SIMILAIRES UTILISANT DES TUBES A RAYONS CATHODIQUES AVEC DEVIATION HORIZONTALE DE L'ANALYSE ACCORDEE DE LA TRAME.
