    • In an electron tube comprising a pyrolytic graphite electrode which is a hollow body of revolution and which has an open end at which it is secured to a substantially coaxially cylindrical electrode support, a substantially cylindrical sleeve of a carbide-forming metal is interposed radially between said end of the pyrolytic graphite electrode and the electrode support. One end of said sleeve is fused around the end of the electrode and the other end is secured to the grid support. Thus, the pyrolytic graphite electrode is secured in an uncomplicated and efficient way with a satisfactory dielectric strength and without affecting the electric field of the tube in operation.
    • 在一个包含热解石墨电极的电子管中,该电极是一个回转中空体,并具有一个开口端,在该开口端处,该开口端固定在一个基本上同轴圆柱形的电极支架上,一个碳化物形成金属的基本上圆柱形的套筒径向插入在所述 热解石墨电极端部和电极支架。 所述套管的一端围绕电极的末端熔合,另一端固定在电网支架上。 因此,热解石墨电极以简单且有效的方式固定,具有令人满意的绝缘强度并且不影响管的电场。
