摘要： A metal halide lamp comprising a luminous sealed tube, a pair of electrodes housed in the luminous tube and rare gas, mercury and metal halide sealed in the luminous tube, characterized in that boron or a boron compound is sealed in the luminous sealed tube in such a manner as not to contact the surfaces of the electrodes. The metal halide lamp is advantageous in that the electrodes are prevented from corrosion and that the blackening with time of the inner wall of the luminous tube is suppressed.

摘要： A shadow mask with a low thermal expandability of an Fe--Ni-based alloy and a high surface hardness is disclosed. This shadow mask includes a mask main body consisting of an Fe--Ni-based alloy containing iron and nickel as main constituents, a large number of fine electron beam apertures formed in the mask main body, and a surface layer formed on the surface of the mask main body and containing at least one compound selected from the group consisting of iron nitride, iron nickel nitride, iron boride, iron nickel boride, iron silicide, and iron nickel silicide.
