Title (EN) FRONT FACE FOR A CATHODE RAY TUBE
(FR) FACE AVANT POUR TUBE A RAYONS CATHODIQUES
Abstract: front page image
(EN)The invention relates to a cathode ray tube comprising a vacuum enclosure, formed by a panel (29, 39) with a front face (26, 35) which supports a luminescent screen (27, 37) and by a rear section in the form of a bell (24). Said front face comprises at least two layers (21, 22; 31, 32) of materials fixed to each other, each of the two layers being at least 20 % of the total weight of the panel. The above structure permits a lightening of the tube and a reduction in production costs.
(FR)Tube à rayons cathodiques comprenant une enceinte sous vide formée par un panneau (29, 39) comportant une face avant (26, 35) servant de support à un écran luminescent (27, 37), et par une partie arrière en forme d'entonnoir (24), ladite face avant comportant au moins deux couches(21, 22; 31, 32) de matériaux solidarisées l'une à l'autre, chacune des deux couches représentant au moins 20% du poids total du panneau. Cette structure permet d'alléger le tube et de diminuer son coût de fabrication.
