Abstract: A cathode device includes an emitter tip for generating electrons. An elongate heater is included having proximal and distal ends. The emitter tip can be located at the distal end of the heater. Two spaced apart legs can extend away from the distal end of the heater, terminating at the proximal end and forming an elongate slot therebetween. Two electrical contacts can compressively engage respective opposite outer surfaces of the two legs at the proximal end of the heater to mechanically secure and electrically connect the two legs of the heater to respective electrical contacts at a junction that is at a location spaced away from the emitter tip to keep the junction cooler.

Abstract: The present invention discloses a cathode ray tube including an electron gun having a heater and a method for manufacturing the same. The heater is formed using a coil and includes a heat-emitting part having a heat-focusing part on which heat generated from the coil is focused and a buffering part for buffering shocks, and a triple coil part formed such that the coil is wound in three levels at predetermined pitches. The pitches of second and third levels of the triple coil part are substantially identical to each other and larger than the pitch of the first level. The present invention can improve the quality and welding reliability of the heater and reduce the quantity of coil required and time required for winding the coil while accomplishing high efficiency heating.

Abstract: A cathode heater includes a patterned conductor embedded within a dielectric substrate. The ceramic substrate has a pair of conductors over the respective surfaces thereof to provide electrical contact for the heater. To assemble the substrates having the conductors, the substrates and printed conductive patterns are fired to provide a composite multi-layer ceramic heater which can be used to heat cathode electrodes in microwave tubes such as travelling wave tubes.

Abstract: In order to bring a high power vacuum tube to full power in a few seconds, it is necessary to heat the cathode quickly to 1100.degree. C. In large tubes, prior art structures cannot be simply enlarged. A novel cathode structure in which the heater element is anisotropic pyrolytic graphite coated with anisotropic pyrolytic boron nitride for insulation and then sintered to the cathode avoids these problems.

Abstract: A dark heater is produced by a method which comprises coating the first coating layer made of an insulating material with a suspension containing heat-resistant particles having a high thermal emissivity, such as W particles, while 0.5 to 1.5 wt. % of a volatile matter such as water remains in the first coating layer to form a dark coating layer. Since the suspension having a low viscosity can be used, the thickness of the dark coating layer can be made highly uniform and the emission characteristics of the heater can be stabilized.
