摘要： A color cathode ray tube having a striped phosphor screen is provided, in which color displacements due to the tube axis (Z-axis) component of the terrestrial magnetism can be decreased at low cost. A positive temperature coefficient thermistor and a degaussing coil are connected in series to an AC power source (AC 100V) via a switch. A rectifier/smoothing circuit is provided in parallel to the positive temperature coefficient thermistor. When the switch is turned on, an ordinary degaussing process due to the AC attenuating magnetic field interlinked to the degaussing coil is performed, and the DC magnetic field in the Y-axis direction interlinked to the degaussing coil decreases the influence of the terrestrial magnetism in the tube axis direction (Z-axis direction).

摘要： A ferromagnetic shielding funnel having a flange at its wider end for reception within the conical portion of a cathode ray tube, the funnel having support members at the corner portions of its flange. Each support member has a base plate which is attached to the flange and a distal end which has been bent into a V-shape for bearing on a respective pin in the wall of the cathode ray tube. For preventing that the funnel comes loose from the pins, the support members comprise further attachment means with which they are attached to a skirt of the flange. Preferably, the base plate is attached to the flange by means of two first connections to a flange portion which is parallel to a long side of the cone portion and two second connections to a flange portion which is parallel to a short side of the cone portion. The extreme ones of these connections are preferably arranged such that bending of the flange at the corner portions is prevented.

摘要： An internal magnetic shield includes a pair of opposing long side walls (1), a pair of opposing short side walls (2), and an opening (3) enclosed by these side walls in the center. The short side walls (2) are provided with notches (4) having a substantially home-plate shape. This configuration can reduce mislanding of an electron beam on the entire screen and easily balance the amount of mislanding due to geomagnetism in the tube-axis direction and in the horizontal direction perpendicular to the tube axis. As a result, a cathode ray tube capable of displaying images without displacement and unevenness of colors can be provided.
