摘要： A cathode ray tube has an electron gun including an indirectly heated cathode structure having a heater therein. The heater has a major heating portion formed of a spirally wound heating wire and two leg portions connected to opposite ends of the major heating portion. The two leg portions are welded to electrical conductors for applying voltages thereto at portions in the vicinity of open ends of the two leg portions, respectively, and the heater is covered with an insulating film except for the portions for welding. The two leg portions includes at least five layers of winding formed by spirally winding heating wires identical with the heating wire of the major heating portion, and the numbers of turns per unit length in each of the at least five layers of winding are smaller than a number of turns per unit length of the heating wire of the major heating portion.

摘要： An indirectly heated cathode for gas discharge tube C1 comprises a heater 1, a double coil 2, a plate member 3, and a metal oxide 10. An electrical insulating layer 4 is formed on the surface of heater 1. Heater 1 is disposed at the inner side of double coil 2. Plate member 3 is disposed along the length direction of double coil 2 at the inner side of double coil 2, which is to be the discharge surface side, and is electrically connected to double coil 2. Also, plate member 3 is grounded by being connected to the ground terminal of heater 1. Metal oxide 10 is held by double coil 2 and disposed to be in contact with plate member 3. Metal oxide 10 is in contact with double coil 2.

摘要： Cathode comprising a substrate (2) supporting a cathode emissive coating, comprising what is called an emissive central zone (12) and what is called a nonemissive peripheral zone (11); according to the invention: the average density and the emissive zone (12) is greater than that in said nonemissive zone (11), the average thickness in the emissive zone (12) is less than that in the nonemissive zone (11). In this way it is possible to significantly limit the drift in cut-off voltage, while still maintaining good maximum emission performance in DC mode and in pulse mode.
