    Abstract: This invention aims to provide a through terminal capable of maintaining air-tightness stably and an X-ray tube having the through terminal. The through terminal comprises a tubular member, a plate member formed of an insulating ceramic material and bonded to an inner periphery of the tubular member in a hermetically sealed state, and pins extending through the plate member so that the portions thereof fitted through the plate member are located inside metallic tubes respectively and bonded to the plate member in a hermetically sealed state through the tubes. The tubular member is provided on an inner periphery thereof with a stepped portion for abutment thereagainst of a plate face of the plate member. The tubular member is formed of an alloy comprising at least iron, nickel, and cobalt.

    Abstract: A ferrofluidic seal arrangement for sealing a high-speed rotary shaft which passes between an environment at atmospheric or high pressure and an environment at high-vacuum is provided, which is especially useful in a high-speed rotating anode apparatus for generating x-rays in a CAT Scan apparatus or the like. A differentially-pumped region between a multi-stage ferrofluidic seal and a single-stage seal insures that no seal bursting into the high-vacuum region occurs. Bearings supporting the shaft are arranged in a mechanically-stable arrangement but are isolated from the high-vacuum environment. Thus, neither the high-vacuum environment nor the differentially-pumped region need be continually mechanically pumped, and a relatively light-weight apparatus results. The apparatus is electrically grounded by transferring the charge on the anode through the high-speed shaft out of the vacuum environment and to a slower-rotating shaft via an electrically conductive, flexible drive belt, the slower shaft rotating at a speed at which grounding by conventional means is feasible.
