Abstract: The present invention provides a high-resolution color picture tube device with a decreased beam spot diameter. The color picture tube device has an electron gun including cathodes, a control electrode, an accelerating electrode, a G3 electrode, a first focusing electrode, a second focusing electrode, and a final accelerating electrode that are arranged in this order. A voltage applied to the G3 electrode is obtained by dividing with a resistor a voltage applied to the final accelerating electrode, and when an electron beam is a non-deflection state, a relationship represented as Va>Vg3>Vfoc2 is satisfied where Va, Vg3, and Vfoc2 denote voltages respectively applied to the final accelerating electrode, the G3 electrode and the second focusing electrode. Thereby, the G3 electrode is applied with a high voltage independently for forming a prefocus lens.

Abstract: The present invention relates to a color display device comprising a color display tube (1) with a front portion having a truncated cone (3), means for generating a plurality of electron beams (5), a shielding (9) of ferromagnetic material extending substantially parallel to the truncated cone (3), and a demagnetizing device having at least two demagnetizing coils (11,12) extending along the outer circumference of the cone (3). The demagnetizing device is arranged to energize the coils(11,12) simultaneously and with a phase difference, resulting in the generation of a rotating magnetic field. As the magnetic field rotates, it can be arranged to substantially coincide with the shape of the shielding (9), resulting in a magnetic field that is parallel to the shielding (9) over a larger part of the shielding surface. This improves the demagnetizing procedure, leading to a better landing performance of the electron beams.

Abstract: An improved Klystron device is disclosed which has opposed electrostatic (ES) magnetic field generating members which are uniformly spaced along a longitudinal axis to form an electron beam chamber. The ES magnetic field generating members produce a magnetic flux which confines an electron beam passing through the chamber when an alternating current (AC) is imposed upon the magnetic field generating members. An additional improvement includes a chamber formed from a single sheet of electron conductive metal having a ladder-like structure symmetrical about a longitudinal hinge which permits the structure to be folded about the hinge to form a suitable electron beam chamber.
