Abstract

L'INVENTION CONCERNE LES TUBES CATHODIQUES. LE SYSTEME DE DEVIATION FAISANT L'OBJET DE L'INVENTION EST DU TYPE COMPRENANT UN CIRCUIT MAGNETIQUE DANS LEQUEL SONT PLACEES, CONCENTRIQUEMENT A CELUI-CI, DEUX PAIRES DE BOBINES CYLINDRIQUES, EN FORME DE SELLE, DE DEVIATION HORIZONTALE ET VERTICALE, DISPOSEES PERPENDICULAIREMENT L'UNE A L'AUTRE, CHACUNE DESDITES BOBINES COMPORTANT DES PARTIES LONGITUDINALES ET D'EXTREMITE RELIEES ENTRE ELLES PAR UNE ZONE DE TRANSITION, ET EST CARACTERISE EN CE QUE, DANS CHAQUE BOBINE, CHAQUE ZONE DE TRANSITION 6 A UNE SECTION TRANSVERSALE D'EPAISSEUR VARIABLE ALLANT D'UNE VALEUR MAXIMALE DANS LA SECTION SITUEE A LA FRONTIERE 7 ENTRE LA ZONE DE TRANSITION 6 ET LA PARTIE D'EXTREMITE 5 OU LONGITUDINALE 4, JUSQU'A UNE VALEUR MINIMALE DANS LA SECTION DIAGONALE DE LA ZONE DE TRANSITION 6, PERPENDICULAIRE AU PLAN DE DEVIATION DU FAISCEAU D'ELECTRONS. LE SYSTEME DE DEVIATION EN QUESTION PEUT ETRE EMPLOYE EN PARTICULIER DANS LES CAMERAS DE TELEVISION UTILISANT LES VIDICONS ET D'AUTRES TUBES CATHODIQUES DU MEME GENRE.
