Abstract: In a television receiver, a dynamic, parabolic correction voltage for focusing is generated by way of a transformer whose primary winding is fed with the line deflection current or a line-frequency voltage and to whose secondary winding a capacitor is connected, which capacitor integrates the sawtooth-waveform current in the secondary winding into a parabolic voltage. New types of picture tubes require a correction voltage which does not have a parabolic profile, rather whose form corresponds approximately to the cross section through the center of a bathtub. It is an object to provide a simple circuit for generating such a bathtub-waveform correction voltage. This is achieved by virtue of the fact that a frequency-dependent network, in particular a series resonant circuit comprising an inductance and a capacitance, is connected in parallel with the capacitor, which network is tuned in such a way that the network effects an additional sinusoidal current with a period duration approximately equal to the line trace period. The circuit is particularly simple, requires no active elements, effects a low power loss, can be used with a current transformer and furthermore enables blanking of the correction voltage during the vertical blanking interval.

Abstract: A method of compensating for and correcting temperature induced focus and distortional errors within a head-up display unit is described. The head-up display is comprised of a cathode ray tube and a plurality of lenses constructed of a plastic material defining a lens train and a mounting device constructed of a metal material. The compensation for the temperature can be accomplished by measuring the difference in thermal expansion between the plastic material and the metal material and conveying the measured difference to an alignment device for an appropriate adjustment.

Abstract: An electron gun assembly in a cathode-ray tube apparatus includes a quadrupole lens that is created in accordance with deflection of electron beams. The quadrupole lens is created by two mutually opposing grids. The two grids have non-circular electron beam passage holes in their mutually facing surfaces. Each electron beam passage hole has a waist portion which minimizes a horizontal or vertical dimension of a region for passing the associated electron beam.

Abstract: A color cathode ray tube apparatus of this invention includes an electron gun. In the electron gun, an intermediate electrode is arranged at the mechanical center between a focus electrode and anode electrode that form a rotationally symmetric bi-potential lens. A disk-like intermediate electrode is arranged at the mechanical center between the focus electrode and intermediate electrode. The disk-like intermediate electrode has an electron beam hole with a diameter larger in the vertical direction than in the horizontal direction. The intermediate electrode has a circular electron beam hole. Voltages are applied to the disk-like intermediate electrode and intermediate electrode such that they form an electron lens similar to that formed when the disk-like intermediate electrode does not exist. Therefore, an electron beam spot is focused in an optimal manner on the entire surface of a phosphor screen, and elliptic distortion is decreased. A good image is displayed on the entire surface of the phosphor screen.

Abstract: A dynamic focus coil produces different selected ampere-turns while consuming constant power and therefore maintaining constant temperature. The focus coil comprises a set of coils that all consume the same power. A selected subset of coils (e.g. two or three) are energized at any given time, the subset being selected to produce the desired focus adjustment. Illustratively, the coils all have the same resistance and are driven by current having the same magnitude and selectable polarity. An alternative embodiment contains a “coarse” set of coils having selected values of ampere turns and a “fine” set of coils having values of ampere turns that fill in between the values of the coarse set.
