Fluorescent screen mfr. for X=ray medical diagnosis appts. - producing positive form by introduction of matrix in body of high-melting material and applying luminous material

摘要

The positive form is filled with glass or metal to produce a negative form as substrate for the fluorescent screen. The two forms are then sepd., and luminous material is introduced into the negative form. The positive form consists of high-melting ceramic and is pressed into a moulten plate of metal or glass for prodn. of the negative form, the luminous material being introduced into the negative form by melting or sintering. The negative form of copper is lined with a refined metal electro-chemically, and its shaft walls are thinned electro-chemically to a thickness of 5 - 30 micrometres. USE/ADVANTAGE - For X-ray image intensifier, X-ray detector, gamma camera, etc. Simplified mfr.
