Abstract
In a vacuum-tight picture-reproducing device having a flat glass faceplate and a metal tray-shaped back case with an outwardly curved bottom and a continuous flange, the flange has a perpendicular extension. The faceplate has end surfaces embraced by the extension and lies on the flange. The end surfaces of the faceplate and the flange with the extension are permanently joined together by a silver-containing tin-base solder. The joint may be covered by a metal layer.
