Abstract: An electron gun for a cathode ray tube includes a triode potion including cathodes, a first electrode, and a second electrode arranged with predetermined gaps therebetween. A plurality of electrodes arranged in sequence starting from a position adjacent to the second electrode. The electrodes receiving a voltage, for example, a constant voltage or a dynamic voltage. The dynamic voltage is synchronized with a deflection signal of electron beams. An anode electrode is positioned having a predetermined gap between the electrode arranged farthest from the cathodes. A support maintains the electrodes at predetermined intervals. One of the electrodes is a multiple-element electrode that includes two interconnected sub-electrodes. Gaps are formed between portions the sub-electrodes of the multiple-element electrode.

Abstract: An electron gun used with a multi-media monitor with a low cathode voltage and improved focusing performance. The electron gun, which includes a cathode, a control electrode, a screen electrode, and a plurality of focusing electrodes to focus and accelerate an electron beam, is designed to satisfy the condition that a value of null is greater than or equal to 0.222 or a value of k is greater than or equal to 0.11, where nullnullT1/D, knullT1/L, T1 denotes a thickness of the control electrode, D denotes a diameter of an electron beam aperture of the control electrode, and L denotes the distance between a beam-entering surface of the control electrode and a beam-emitting surface of the screen electrode.

Abstract: A base cap for a cathode ray tube (CRT) preventing insulation breakdown between a lead pin to which a high voltage is applied and a lead pin to which a comparatively low voltage is applied. Insulation breakdown due to poor application of a silicone composition between a stem of the CRT and a flange of the base cap is avoided. The base cap includes a cylindrical housing, a flange extending radially outward from the edge of the cylindrical housing and including holes into which lead pins fixed to the stem of an electron gun of the CRT are inserted; and at least one isolation element on the surface of the flange, facing the stem, for preventing breakdown of insulation between the lead pins.
