    摘要: Deflector for cathode-ray tube comprising a pair of horizontal deflection coils and a pair of vertical deflection coils, the two pairs being in the shape of a saddle and isolated one from the other by a separator, a frustoconical shaped ferrite ring at least partially covering the deflection coils, the deflector being characterized in that it includes to the rear of the deflection coils, between the horizontal and vertical deflection coils, four field shapers placed symmetrically with respect to the axes of symmetry of the deflector. These shapers are placed so as to increase the amplitude of the second harmonic of the potential of the vertical deflection field without affecting the fundamental of the said potential in order to act on the phenomena of coma appearing on the horizontal edges of the image formed on the tube screen.

    摘要: In a color display tube of the so-called "in-line" type, the magnetic field which extends substantially parallel to the plane through the beam axes is distorted so as to be locally pincushion-shaped by means of field shapers at the end of the electron gun system. This effects coma correction for the rasters produced by the three electron beams at the display screen, without causing substantial deflection defocusing of the side beams.

    摘要: The present invention relates to an inline type color picture tube having a coma distortion correcting mechanism in electron guns. A shield cup is attached to the tips of the electron guns. Three electron beam through-holes are formed in the shield cup in the inline direction. Ring-shaped magnetic material members are arranged around the two outside electron beam through-holes among those three through-holes. This magnetic material member is made of a material of a high permeability. Further, each ring-shaped magnetic material has a gap portion on the side opposite to the central electron beam through-hole. The gap portions of the ring-shaped magnetic materials arranged around both of the outside through-holes have shapes which are symmetrical in the lateral direction around the central electron beam through-hole as a center.

    摘要: An improved color picture tube has an inline electron gun for generating and directing three electron beams, comprising a center beam and two outer beams, along coplanar paths toward a screen of the tube. The three beams pass through a deflection zone adapted to have vertical and horizontal magnetic deflection fields established therein. The improvement comprises the inclusion of means for nonlinearly increasing the effect of the vertical magnetic deflection field on the center beam relative to the outer beams with increasing angles of vertical deflection of the beams.

    摘要: The present invention provides an improvement in a color picture tube having an inline electron gun for generating and directing three inline electron beams, comprising a center beam and two outer beams, along initially coplanar paths toward a screen of the tube. The beams pass through a deflection zone adapted to have two orthogonal magnetic deflection fields established therein. A first of the fields causes deflection of the beams perpendicular to the inline direction of the beams, and a second of the fields causes deflection parallel to the inline direction of the beams. The improvement comprises the electron gun including four magnetically permeable members located near the exit of the electron gun in a fringe portion of said deflection zone. A first and a second of the members are located between the center beam path and a first and second outer beam path, respectively. A third and a fourth of said members are spaced from the first and second members, respectively, and are located on the outside of the respective outer beam paths. The first and third members and the second and fourth members have means for bypassing a part of the fringe portion of the first of the two orthogonal magnetic deflection fields, at the members, around the respective outer beam paths, while allowing another part of the same fringe portion, at the members, to pass through the respective outer beam paths. The first and second members have means for bypassing a part of the fringe portion of the first of the two orthogonal deflection fields, at the members, around the center beam path, while allowing another part of the same fringe portion, at the members, to pass through the center beam path.

    摘要: In a color cathode-ray tube of the plural-beam type wherein the beams originate on a horizontal or vertical straight line and are directed into fields produced by a horizontal-vertical electromagnetic deflection yoke at predetermined incident angles to each other so as to converge at a color screen, magnetic shielding means, for example, secured to electron beam convergence plates, are disposed for selectively shielding at least one of the beams from the leakage flux produced by the horizontal-vertical electromagnetic deflection yoke in deflecting the beams in the direction of the line of origination thereof, whereby such leakage flux acts selectively on only the unshielded beam or beams for correcting a deviation between the positions of rasters on the color screen produced by the plural beams.
