摘要： An improved cathode structure in an electron gun for a cathode ray tube comprises a sleeve having a cylindrical shape, a heater disposed in the interior of the sleeve, a cap disposed at the upper portion of the sleeve, and an electron-emitting material layer coated on the outer top surface of the cap. A gap having a dimension that is 13.5% to 15.5% of the inner diameter of the sleeve, is defined between the sleeve and the heater, thereby improving an overshoot in emission of electrons at an initial operation state of heater.

摘要： An indirect cathode sleeve and manufacturing method thereof capable of substantially reducing electric power consumption of a heater disposed inside the cathode sleeve and simultaneously reducing a picture-producing time by oxidizing an inside surface of the cathode sleeve and reducing an outside surface thereof. The cathode sleeve includes a heater disposed inside the cathode sleeve; a base metal formed at the top of the cathode sleeve; an electron-emitting material layer formed at the outside surface of the base metal; and an indirect cathode sleeve including a black inside surface and a white outside surface. The method for manufacturing the indirect cathode sleeve includes the steps of forming a structure of a cathode sleeve consisting of a bimetal which consist of a Nickel-Chrome alloy at an inside surface of the cathode sleeve and a Nickel alloy at an outside surface of the cathode sleeve; oxidizing the inside surface of the cathode sleeve through a high temperature wet hydrogen environment; selectively etching the outside surface of the cathode sleeve and, as a result, forming a base metal at the top of the cathode sleeve; and forming an electron-emitting material layer at the outside surface of the base metal.
