Abstract
Perfections introduced into cathode ray tubes characterized by comprising a shell that includes a target area for an electron beam, means for creating a convergent electron beam having a crossing point and arranged in a plane offset with respect to said area of white, a first deflection means for variably deflecting the electron beam in said plane at an angle having a deflection center disposed below and laterally with respect to said target area and a second deflection means comprising a pair of pieces of magnetic poles disposed respectively in front of and behind said plane in a region below said target area and suitable for creating a magnetic field of uniform magnetic polarity between them in the path of the beam deflected by said first deflection means, to make that the beam of electrons, when passing through it, is bent in an essentially vertical direction, taking said polar pieces a shape that creates a slow effect in said beam, effect having relatively different forces of lens action on the beam in different parts of the deflection of the beam, to thereby change the place of the crossing point according to the deflection of the beam.
