Abstract: An electron beam gun comprises a beam waveguide and an accelerating anode fixed thereto. The accelerating anode is connected with the aid of high-voltage insulators and through a cathode plate to a cathode assembly. The cathode assembly comprises a linear hot cathode fixed with the aid of two cathode carriers and a focussing electrode which is coaxially arranged with respect to the linear hot cathode and encompasses it with the aid of a two-sided surface. The beam waveguide is separated from the accelerating anode with the aid of rack panels which rigidly fix the accelerating anode to the beam waveguide in such a way that a space is formed therebetween. In order to hermetically separate cathode and anode parts of the projector, the accelerating anode is provided with a plate rigidly connected thereto.

Abstract: The invention is a cathode-ray tube (CRT) and method of manufacturing the CRT having a contrast enhancing coating on the exterior surface of the viewing faceplate. The contrast enhancing coating reduces the transmission of faceplate of the CRT by about 50%. The coating also yields gloss values in the range of 70 to 90. The manufacture comprises the steps of preparing an intermediate formulation containing a hydrolyzed organic silicate, diluting the intermediate formulation with an organic solvent and adding a contrast enhancing material to provide a final formulation, spraying the final formulation onto the faceplate to form the coating, heating the faceplate to cure the coating, and rinsing the coating, thereby forming a stable contrast enhancing coating on the faceplate.
