摘要： A method and apparatus for improving magnetic shielding in mask-frame-assemblies. The system includes providing a cathode ray tube, a mask frame assembly disposed within the cathode ray tube and at least one magnetic shield disposed on the edge of the mask frame assembly. These magnetic shields provide shielding for the horizontal component of the terrestrial magnetic field and thus reduces distortion in the picture displayed on the tube.

摘要： An internal magnetic shield is joined to a color selection electrode structure including a color selection electrode, a pair of longer side frames supporting the color selection electrode with tension being applied and a pair of shorter side frames joined to the pair of longer side frames. Magnetic shielding members inclined at an inclination angle null (nullnull0null) to a tube axis are provided on lateral surfaces of shorter sides of the internal magnetic shield. Phosphor screen side edges of the magnetic shielding members are located between the color selection electrode and a plane that passes through color selection electrode side ends of the pair of shorter side frames and is perpendicular to the tube axis. In this manner, magnetic shielding characteristics can be improved against not only a transverse magnetic field but a tube axis magnetic field. Consequently, mis-landing of the electron beam caused by terrestrial magnetism can be prevented, thereby providing a cathode ray tube with reduced color displacement in a screen.

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： Color display tube having a display screen with a pattern of phosphor elements. To reduce mislanding errors of the electron beams, particularly in the y-direction, the color display tube is arranged within an external magnetic shield which is constituted by an open arrangement (frame) of bars of a soft-magnetic material. The bars jointly constitute, for example the ribs of a block.

摘要： A compact color monitor device that utilizes active and passive magnetic shielding to eliminate the visible distortion of color displays due to externally-imposed magnetic fields. The color monitor device can be installed in standard 19-inch EIA rack enclosures used on-board surface vessels and remain operable with no color distortion when the vessel is subjected to .+-.5 Oersted degaussing fields. The color monitor device includes a quick-degaussing circuit for degaussing internal components in approximately 1/60 of a second.
