    摘要: Bei einer vakuumdichten Bildwiedergabevorrichtung mit einer ebenen Frontscheibe (5) aus Glas und einer metal lischen Wanne (1) mit einem nach außen gewölbten Boden und einem umlaufenden Flansch (3) als Rückseite ist der Flansch (3) mit einem Ansatz (4) versehen. Auf dem Flansch (3) liegt die Frontscheibe (5) auf und ihre schmalen Seiten (6) werden von dem Ansatz (4) umfaßt. Zwischen diesen schmalen Seiten (6) der Frontscheibe (5) und dem Flansch (3) mit dem Ansatz (4) besteht ei ne stoffschlüssige Verbindung aus einem Lötzinn (9) mit einem Silberanteil. Die Verbindung kann durch einen metallischen Überzug (12) abgedeckt sein.

    摘要: An electron beam window (10) is protected from damage by a high energy electron beam (15) by providing an electrically conductive path in the form of one or more conductive layers (26 and/or 27) earthed (18, 21) to a structure (12) of an electron beam gun (11). The electrically conductive layers (26 and/or 27) are adhered to their respective surfaces (24 and/or 25) and may comprise a conductive layer that is sufficiently thin that it will not significantly impede the passage of electrons through the window (10). Each layer (26 and/or 27) is preferably formed of aluminium but could also be formed from magnesium, titanium, platinum, gold, indium tin oxide, or silica doped to make it electrically conductive. Alternatively, the electron beam window (10) can be made conductive by incorporating an electrically conductive dopant in the diamond, or by ion implantation of at least one of the surfaces (24, 25).

    摘要: To provide an electron tube having good airtightness and being appropriate for mass production, indium (23) affixed to the inner surface of a sealing metal support member (24) is provided between a side tube (10) and input faceplate (21). The input faceplate (21) is pushed against the side tube (10). As a result, the indium (23) is squeezed by a pressure receiving surface (70) provided on the end face of the side tube. Since the pressure receiving surface (70) is in a generally declining shape from the inside out, the force of the pressing surface (70) causes the indium (23) to flow outward toward the sealing metal support member (24). Therefore, the indium (23) is firmly affixed to the pressure receiving surface (70), and the side tube (10) and input faceplate (21) can be reliably sealed by the indium (23).
