Abstract

Tube à rayons cathodiques et notamment tube de prise de vues, dont la paroi intérieure de l'enveloppe en verre est recouverte d'un matériau électro-conducteur. Afin de former des électrodes de paroi séparées, ce recouvrement est interrompu dans la proximité d'électrodes s'étendant transversalement au recouvrement de la paroi et supportées par une face porteuse s'étendant transversalement à l'axe longitudinal du tube. A l'endroit de chaque interruption, l'enveloppe présente une réduction étagée du diamètre decroissant, le premier degré sert de face porteuse à l'électrode s'étendant transversalement au recouvrement de la paroi et sur une partie des parois du second degré est appliquée l'interruption de recouvrement. Les interruptions ainsi obtenues n'exercent pas d'influence perturbatrice sur le faisceau d'électrons dans le tube. Application : tube de prise de vues en télévision.
