摘要： The invention relates to an electron gun triode for a cathode ray tube in which the cathode has a projecting emissive zone, centred on the Z-axis of the gun and which advances toward the first electrode. The projecting emissive zone does not have any rotational symmetry around the said first axis.
Applications: Cathode ray tubes

摘要： The invention relates to a main focusing lens for a three-colour cathode ray tube electron gun, in which the aperture of each electrode comprises a rectangular aperture whose large dimension is along the horizontal axis (Ox) and terminating at its two ends in two identical semi-ellipses of order n that are symmetric with respect to the said axis of the gun (Z) and of formula: x a 2 n + y b 2 n = 1 in which x = a cos n Φ; y = b sin n Φ,

the coefficient n has a value different from 1,
a is half the width of the ellipses of order n along the horizontal axis (Ox) and b being half the height of the ellipses of order n along the vertical axis (Oy),
x represents the abscissa of a point lying on the ellipse of order n and y is the ordinate of a point lying on the ellipses of order n,
Φ is an angle which varies in one quadrant between 0° and 90°.
