Abstract: The present invention relates to an inorganically insulated heater having a long life for use in air flow sensors, cathode ray tube cathode heaters etc., wherein the distribution of inorganic insulating particles of the whole insulating layer is made uniform and thereby the development of cracks and the like in the insulating layer is reduced and breaking of wire and dielectric breakdown occur with difficulty even at high temperatures and under strong vibrations.

Abstract: In the dip coating of aluminum oxide coated heaters to provide an outer dark coating consisting essentially of tungsten, a coating bath is used which is substantially rheologically stable, i.e., one in which the rate of settling of the tungsten particles is extremely slow.

Abstract: A refractory metal heater wire is first coated in conventional fashion with a first coating of insulating material, e.g., aluminum oxide. The coating is then dried in air at a temperature below which oxidation of the heater wire occurs for a time sufficient to completely remove all solvents from the first coating. Then, a second coating of a darkening material is applied over the first coating. The complete removal of solvents from the first layer prior to the second layer application step reduces penetration of the material of the second layer into the first layer.

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: 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.
