摘要： A degaussing circuit for compulsorily degaussing a picture tube of a CRT monitor by causing alternating current to flow through a degaussing coil. A switching part, connected to a first end of the degaussing coil, switches a current flowing into the degaussing coil on/off. A chargeable device connected to the first end or to a second end of the degaussing coil removes a potential difference across the degaussing coil when the switching part is turned off. Alternatively, chargeable devices may be connected to both the first and second ends of the degaussing coil. Thus, an electromagnetic field is prevented from being generated by the residual current in the degaussing coil, to thereby meet electromagnetic field safety standards for the monitor.

摘要： A shadowmaskless tracking cathode ray tube control circuit is described, comprising a control loop, which is coupled to a deflection unit of a shadowmaskless tracking cathode ray tube. The shadowmaskless tracking cathode ray tube control circuit further comprises a loop gain control means for compensating the loop gain of the control loop in dependence on the inverse value of the beam current in the shadowmaskless tracking cathode ray tube. The effect is that a constant loop gain is created, which is independent of the beam current.

摘要： A CRT apparatus is composed of a CRT, a deflection yoke, a velocity modulation coil, and a magnetic member. The CRT includes a glass bulb made up of a panel and a funnel connected together and an electron gun housed within the glass bulb, and emits an electron beam from the electron gun toward a phosphor screen formed on an inner surface of the panel. The deflection yoke includes a horizontal deflection coil and a vertical deflection coil, and scans the electron beam over the phosphor screen. The velocity modulation coil is arranged outside the CRT, and modulates a velocity at which the electron beam is scanned horizontally. The magnetic member is arranged to surround an outer circumference of the CRT with the velocity modulation coil positioned therebetween, so as to cover a position corresponding to a space between axially aligned electrodes of the electron gun.

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： Two closed-loop coils are respectively set at the top or the bottom of a cathode ray tube. These two closed-loop coils serves in a pair as a cancel coil. Each closed-loop coil is positioned so as to make an interlinkage with the magnetic field leakage that escapes from the deflection yoke, a part of the closed-loop coil running almost in parallel to the top or bottom edge of an effective display region of a front panel.

摘要： The present invention relates to a colour picture tube and to a manufacturing method for a colour picture tube. The colour picture tube includes a shadow mask which is secured to a mask frame. In order to improve the shielding effect, a shielding plate, which shields external magnetic fields, is secured to at least one longitudinal bar of the mask frame. By means of such a shielding plate, the picture quality of a colour picture tube can be improved and the manufacturing efforts can be simplified in comparison with conventional colour picture tubes.
