Abstract: A cathode ray tube apparatus having a glass panel in front of the phosphor screen made of a material which has an X-ray absorption coefficient larger than that of the backing on which the phosphor layer is applied. The two panels are separated by means of a spacer and a liquid coolant is incorporated into the space between the panels to enhance the heat radiation effect of the phosphor surface and to avoid the radiation of X-rays.

Abstract: A cathode ray tube includes an envelope consisting of a flat panel, a funnel and a neck. The flat panel has a phosphor layer and a conductive layer respectively coated on its inner surface and the funnel is provided with an anode button. An anode contactor is attached to the anode button at its inner end. In this case, the anode contactor consists of a base portion made of a flat plate and extended substantially along the inner surface of the funnel and a leaf contactor integrally extended from the base portion so as to resiliently contact with the conductive layer coated on the inner surface of the flat panel. The base portion of the anode contactor is provided with a projection near a portion from which the leaf contactor is extended, the projection contacting with the inner surface of the funnel, and provided with an insertion aperture at a portion opposite to the portion from which the leaf conductor is extended, the inner end of said anode button engaging with said insertion aperture.

Abstract: In a flat cathode ray tube, a flat glass tube is of three-element structure includes a screen panel integrally provided with skirt portions which are erected from the screen panel along the front end and the opposite side portions thereof continuously, a front panel or a back panel of a sheet-like configuration, and a funnel portion having a neck portion. The screen panel, front panel and funnel portion are combined through frit glasses, and a phosphor screen is formed on the inner surface of the screen panel. An electron gun is disposed within the neck portion, so that an electron beam generated from the electron gun collides with molecules within the flat glass tube to generate negative ions. The negative ions are accelerated and irradiated at the center portion on the skirt portion provided at the front end of the screen panel, whereby the phosphor screen is prevented from being burned by the ions and degradation of the frit glass due to impact of the negative ions is prevented.

Abstract: An improved electron gun beam for a three color gun which has a central cathode and side cathodes mounted on either side of the central cathode which produce beams for different colors which pass through first and second grids and a main electron lens and wherein the first and second grids are generally conically shaped so that they extend toward the central cathode and have further indentations in their central portion which extend toward the central cathode and wherein the thickness of the second grid at the center wherein the beam of the central cathode passes therethrough is less than at the portions of the second grid where the beams from the two side cathodes pass therethrough and also where the distance between the central cathode and the indented portion of the first grid is larger than the distance between the two side cathodes and the distance to the first grid and/or the distance between the second and first grids is larger at the portion where the central cathode beam passes therethrough than where the beams of the two side cathodes pass therethrough so as to provide optimum focusing voltage values and the voltage difference for optimum focusing for the respective beams is constant over the entire cathode current operating ranges.

Abstract: An electron gun of uni-potential type is disclosed, which includes a main electron lens system consisting of a front electron lens system formed of a third grid and a fourth grid and a rear electron lens system formed of the fourth grid and a fifth grid of which the electron lens action regions are separated from each other. In this case, the electron lens diameter of the front electron lens system is selected smaller than that of the rear electron lens system, and the aperture diameter of the fifth grid in the rear electron lens system is selected larger than that of the fourth grid, and may be nearly as large as the inner diameter of the tube in which it is placed for use.
