SYSTEME DE DEVIATION DE FAISCEAU D'ELECTRONS POUR TUBE A RAYONS CATHOLIQUES MONOCHROME |
摘要 |
The coils (20, 21) of an astigmatism corrector (13) for an electron beam (12) of a cathode ray tube (6) are positioned on a flexible support (40). The support is disposed around the neck (8) of the tube and positioned at least partially adjacent the back part of at least one pair of deflection coils (3, 4), so as to reduce interaction of the fields produced by the astigmatism corrector (13) with the elements of the electron gun (7). |
