Title (EN) COLOR PICTURE TUBE HAVING A LOWER EXPANSION TENSION MASK ATTACHED TO A HIGHER EXPANSION FRAME
(FR) TUBE A IMAGE COULEUR DOTE D'UN MASQUE A TENSION A FAIBLE EXPANSION FIXE SUR CADRE A EXPANSION ELEVEE
Abstract: front page image
(EN)A color picture tube (10) has a tensioned mask (24) supported by a support frame (50) mounted within the tube. The mask has a significantly lower coefficient of thermal expansion than the frame. The mask has an active apertured portion (40) formed by a plurality of parallel vertically extending strands (42), through which electron beams pass during operation of the tube, and two opposite side border portions (46, 48) outside the active apertured portion. The two opposite side border portions have tie bars (49) that extend between the vertical strands of the mask. The tie bars accommodate expansion of the frame, while substantially maintaining the positions of the vertical strands in the active portion of the mask.
(FR)L'invention concerne un tube à image couleur (10) doté d'un masque à tension (24) porté par un cadre de support (50) monté dans le tube. Le masque a un coefficient d'expansion thermique nettement inférieur à celui du cadre. Ce masque comprend une zone active à ouvertures (40) constituée de plusieurs bandes parallèles s'étendant verticalement (42), à travers lesquelles des faisceaux d'électrons passent pendant le fonctionnement du tube, et deux zones de bords latéraux opposés (46, 48) situées à l'extérieur de la zone active à ouvertures. Les deux zones de bords latéraux opposés présentent des colonnes (49) qui s'étendent entre les bandes verticales du masque. Ces colonnes permettent l'expansion du cadre, en maintenant à la fois pratiquement les positions des bandes verticales dans la zone active du masque.
