Abstract

Bei einem direkt geheizten Sorptions-Getterkörper zur Gasaufzehrung reaktiver Restgase in vakuumdicht abge­ schlossenen Behältern, insbesondere in fladen Bildanzeige­ geräten, ist vorgesehen, daß ein Isolierkörper (1) mit zwei elektrischen Kontakten (2) versehen ist und daß die Getter­ masse (3) auf den als Träger dienenden Isolierkörper (1) und die Kontaktstellen (4) aufgebracht ist. For a directly heated sorption getter body Gas consumption of reactive residual gases in vacuum tight closed containers, especially in flat image display devices, it is provided that an insulating body (1) with two electrical contacts (2) is provided and that the getters mass (3) on the insulating body (1) serving as a carrier and the contact points (4) is applied.

Der erfindungsgemäße Sorptions-Getterkörper wird insbesondere bei flachen Bildanzeigegeräten verwendet. The sorption getter body according to the invention is used especially in flat image display devices.
