16 Jan 1996TL;DR: In this paper, a shadow mask with a low thermal expandability of an Fe-Ni-based alloy and a high surface hardness is disclosed, which includes a mask main body consisting of a Fe--Ni alloy containing iron and nickel as main constituents, and a large number of fine electron beam apertures formed in the mask's main body.
Abstract: 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.

Abstract: Internal alkynes were hydrogenated quantitatively to the corresponding cis -alkenes over nickel boride (Ni 2 B), prepared on borohydride exchange resin (BER) in methanol under hydrogen atmosphere. Further hydrogenation was very slow under the reaction conditions, and pure cis -alkenes were conveniently isolated in excellent yields. Hydroxy and ester functional groups did not interfere with the semihydrogenation.
