摘要： A cathode ray tube display having an in-line tube includes an electromagnetic unit for dynamically influencing the path or shape of the electron beams. The power for supplying current to the electromagnetic unit is drawn from the line deflection circuit, either through supply coil on a transformer arranged in parallel with the line deflection coil, or from a supply coil sound around the deflection unit core.

摘要： A color display device having an electron gun, a display screen, a color selection electrode and a deflection unit. The distance between the electron beams in the x-direction is dynamically varied, whereby the distance in the deflection space decreases as the beams are deflected in at least one direction. The reduction of the distance enables the distance between the color selection electrode and the display screen to be increased in that direction. As a result, the curvature of the color selection electrode is increased, which has a positive effect on the strength and the doming and microphonic properties of the color selection electrode.

摘要： A cathode ray tube includes an electron gun having a beam-shaping portion (20) for generating electron beams (7-9), a prefocusing system (30) of electrodes (31, 32) across which a prefocusing voltage is supplied during operation so as to form an electron-optical prefocusing lens, and a main lens system (40) of electrodes (32, 41) across which a main lens voltage is applied during operation so as to form an electron-optical main lens. The electrodes (31, 32, 41) are provided with securing means (48) for connection to an insulating supporting body (47) and with apertures (16) for passing the electron beams (7-9). Electrode (32) protrudes toward electrode (31) in such a way that the mutual distance (l2) between the two electrodes at the location of the apertures (16) therein is smaller than their mutual distance (l1) at the location of their respective securing means (48). The two electrodes (31, 32) are spaced apart at the location of the apertures (16) substantially at a distance limited by electrostatic breakdown.

摘要： An electron gun includes plural aligned charged grids each having an aperture (in a monochrome CRT) or plural apertures (in a color CRT) through which an electron beam (or beams) is directed. The beams emitted by a cathode sequentially transit a beam forming region (BFR), a dynamic focus lens and a main focus lens prior to being incident on the CRT's display screen. The electron beam tends to expand in diameter in the direction of the CRT's display screen. This results in an increase in the focusing effect on the electron beam of the electron gun's grids in proceeding from the BFR toward the display screen where the beam passing apertures in the various grids are of the same size. To increase electron beam focusing sensitivity while reducing the beam's dynamic focus voltage, the beam passing apertures in the gun's dynamic focus lens are provided with progressively reduced size in proceeding toward the electron gun's cathode.

摘要： A electron gun has a plurality of arranged tubular electrodes for passing electron beams inside the tubular electrodes, and the tubular electrodes are fixed to support rods respectively by support members. At least one of the tubular electrodes is separated into two parts, and the separated two tubular electrode parts are connected electrically with each other by a coil member provided therebetween. The coil member is composed of a wire with its tip ends being located within the spaces formed by the support members. A desired electron beam modulation effect can be provided without interrupting transmission of a modulation magnetic field from the exterior, and also electric field emission of electrons from the tip ends of the coil member is suppressed.

摘要： An electron gun for a cathode ray tube includes a triode having cathodes, a first grid and a second grid, one or more third grids through which electron beams emitted from the cathode pass, a fourth grid opposing the third grids and forming a main focus lens with the third grid, a shield cup connected to the fourth grid and supplying a high voltage to the fourth grid, and a correction grid disposed between the fourth grid and the shield cup and having R, G, and B beam through holes arranged along a line. The R and B beam through holes have openings with asymmetrical shapes that are symmetrical with respect to each other and relative to the straight line, balancing astigmatisms and improving resolution.

摘要： When an interval between a Gm electrode and a cathode is broadened with temperature, a potential change similar to a case that a Gm electrode voltage is lowered is generated. If a cathode voltage is constant, a quantity of electrons which pass is decreased whereupon a screen of a cathode ray tube becomes dark. A Gm electrode voltage control circuit is provided to a Gm electrode voltage source for control an applied voltage to the Gm electrode by time information from a time-measuring circuit such that the change of the interval between the cathode and the Gm electrode is corrected during a period of time between the time the voltage is applied to each electrode of a Hi-Gm tube and the time the change of a size of the interval between the cathode and the Gm electrode is saturated.

摘要： The thickness of a face panel is greater at a peripheral edge portion than at a center portion. At the inner surface of the face panel, a curvature radius in a short axis direction on a long axis is set to decrease from the center of the face panel toward a long axis end and, with L representing a distance from the center of the face panel to the long axis end, has a minimal value at a position spaced from the center of the face panel more toward the long axis end than L/2. A phosphor screen on the face panel has phosphor layers and non-emitting black layers and a percentage of the non-emitting black layers per unit area at least in the neighborhood of a diagonal axis end of the face panel is equal to or smaller than that at the center portion of the face panel.
