摘要： A focus electrode 4 is constituted by first type of focus electrode groups 43, 45 to which a first focus voltage is applied, and second type of focus electrode groups 44, 46 to which a second focus voltage is applied. Between the first type of focus electrode groups and the second type of focus electrode groups are formed a lens for correcting the field curvature and an electrostatic quadruple lens. The center axes of the outer electron beam passage holes in the first type of focus electrode forming the lens for correcting the field curvature are deviated on a horizontal plane from the center axes of the outer electron beam passage holes in the second type of focus electrode. The electrostatic quadruple lens produces dissimilar intensities for the outer electron beams and for the center electron beam. Therefore, the outer electron beam passage holes work to deflect the outer electron beams toward the center electron beam with an increase in the deflecting amount of the electron beams, and a favorable resolution is obtained on the whole screen of the cathode-ray tube.

Between the first type of focus electrode group and the second type of focus electrode group are formed a lens at least having a lens action for correcting the field curvature and an electrostatic quadrupole lens. The center axes of the outer electron beam passage holes in the first type of focus electrode forming the lens at least having a lens action for correcting the field curvature are deviated on a horizontal plane from the center axes of the outer electron beam passage holes in the second type of focus electrode.

摘要： A color cathode-ray tube including a main lens section comprising an anode to which an anode voltage is applied, and a focus electrode. The focus electrode has first type of focus electrode group to which a first focus voltage is applied, and a second type of focus electrode group to which a second focus voltage is applied which is obtained by superposing on a predetermined voltage a voltage that changes depending upon the deflecting amount of the electron beams. Between the first type of focus electrode group and the second type of focus electrode group are formed in a dynamic lens and an electrostatic quadrupole lens. Three electron beam passage holes are formed in the electrodes that form the dynamic lens and the centers for the outer electron beam passage holes in the first type of focus electrode group are deviated relative to the centers of the outer electron beam passage holes in the second type of focus electrode group in the horizontal direction. The electrostatic quadrupole lens exhibits different intensities for the outer electron beams relative to the center electron beam.

摘要： A color cathode ray tube includes an in-line electron gun having a main lens with recessed apertures. The main lens is formed by two electrodes. These electrodes have outer edges and recessed apertures which allow passage of three in-line electron beams and which are arranged at a distance d1 and d2, respectively, from the outer edges. The outermost apertures are asymmetric. The difference d1-d2 and the asymmetry of the outermost apertures is such that both the beam displacement and the core haze asymmetry are minimal.

摘要： An in-line gun for a cathode ray tube includes three beam-passing holes formed in an electrode and at least two reference holes formed in the electrode. The three beam-passing holes are aligned in line. The two reference holes are positioned opposite to each other with respect to a middle beam-passing hole in the three beams-passing holes. The two reference holes are of different shapes. One of the two reference holes is a round hole and the other is an elongated hole. The elongated hole is formed by elongating a hole having a center located at a position opposite to that of the round hole toward the middle beam-passing hole. The elongated hole may be defined by combining a small-diameter hole, a large-diameter hole, and two lines tangent to the small-diameter hole and the large-diameter hole. The large-diameter hole is closer to the middle beam-passing hole than the small-diameter hole.

摘要： A color cathode ray tube apparatus is provided with an electron gun which has a common large-aperture electron lens on which three electron beams are incident. Since the electron gun has individual electron lenses for individual electron beams, the electron beams can be properly converged and focused on a screen. Thus, the apparatus enjoys a satisfactory picture characteristic.

摘要： For use particularly in a color cathode ray tube electron gun, means for diverting an electron beam from a straight line path. The beam diverting means has general utility, but is disclosed as part of a quadrupole lens for correcting astigmatism introduced by an associated self-converging yoke. The beam bending feature in the dynamic quadrupole compensates for convergence errors undesirably introduced by the dynamic focus voltage.

摘要： The effective aperture sizes of the final focusing and accelerating electrodes of an in-line electron gun structure for color cathode ray tubes are increased by elongating the apertures, expanding the outer edges of the side apertures, and surrounding the apertures with a peripheral raised rim which balances the asymmetry introduced into the apertures by enlargement. Partitions between the aperture may be radiused so their center height is lower than the height at the edges. The raised rim of the final accelerating electrode is generally higher than the raised rim of the focusing electrode.
