Abstract:
A heat radiation element has a substrate and a heat radiation layer formed on the substrate by oxides of a chromium-containing alloy. The oxides contain at least 35% by weight of chromium based on the total weight of the metals constituting the oxides.
Abstract:
An electron discharge device having an anode comprising a plurality of hollow pipes. The pipes have relatively thin, continuous walls of uniform dimension and generally may be of any cross-sectional geometry. The pipes are adjacently disposed in a circular or linear array such that the electron-intercepting surfaces thereof are oblique to the direction of the electron beams. The angles of incidence of the electron beams on the pipe surfaces preferably have a minimum average value. A cooling medium is circulated through the interiors of the pipes.
Abstract:
A projection picture tube comprises a vacuum vessel, an anode support member received in said vessel, a fluorescent film coated on the upper surface of said anode member and an electron gun assembly for ejecting electron beams on said fluorescent film, said anode member consisting of a hollow metal body through which a cooling fluid is caused to flow.
Abstract:
In an electron beam discharge tube a fluid cooled electron collector has two cooling conduit systems each cooling a different part of the length of the collector, the interior surface having three main portions. Two portions are curved when viewed in section and extend over the length of the cooling stages. The third portion forms a conically tapered step between the first two portions, and extends over the region between the two cooling stages. The interior surface is shaped so that this third portion is subject to a lower intensity of electron bombardment than the average intensity elsewhere.
