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 cathode ray tube including an internal magnetic shield in the shape of a hollow rectangular frustum including two long sides opposite to each other and two short sides opposite to each other, having an opening at its top and bottom attached to a mask and a frame. Each long side has a long side extension at a horizontal center located at the top of the internal magnetic shield where an electron beam enters the internal magnetic shield. The long side extensions enable the magnetic shield to reduce the deviation of an electron beam within the magnetic shield caused by an external magnetic field such as that caused by terrestrial magnetism.

摘要： A cathode ray tube is provided, in which the flatness of a tension mask constituting a color-selection mechanism is maintained by a suitable stretching force, while with the tension mask, the influence of external magnetic fields, such as the terrestrial magnetism is suppressed, and the shifting of the electron beam is reduced. A tension mask made of a magnetostrictive material is used, the tension mask is stretched by a stretching force in a range maintaining the flatness of the tension mask, and the direction and strength of the stretching force are set such that vertical magnetic permeability of the tension mask increases, due to a magnetoelastic effect caused by the stretching force in the magnetostrictive material of the tension mask.

摘要： In a cathode ray tube including a panel provided with a phosphor screen, a funnel integrated with the panel, an electron gun disposed inside the funnel, a magnetic shield (1) for shielding an electron beam (5) emitted from the electron gun against an external magnetic field, and a frame (2) for holding the magnetic shield (1), the magnetic shield (1) includes, at a portion to be joined with the frame (2), a bent portion (20) bent toward a tube axis side, and a thickness T of the bent portion (20) at its edge on the tube axis side is 0.08 mm or less. By making the thickness T small, halation that is liable to occur in a cathode ray tube with a large deflection angle can be suppressed because electron beams reflected from an end face (11) and allowed to reach the screen without being shielded by the frame (2) are reduced.
