Abstract: A lighting fixture exclusively for use in a tent comprises an independent lighting fixture attached to a vault of an inner tent by means of a magic tape, a double-faced adhesion tape or a clamp to provide an easy, convenient and efficient lighting in the tent.

Abstract: A semiconductor packaging device includes a printed circuit board substrate, a mold gate formed on a periphery of the printed circuit board substrate through which a package encapsulant is poured to enclose electric elements mounted on a side of the printed circuit board, and a layer of non-metallic material covered on the side of the printed circuit board substrate in the mold gate area. The package encapsulant, after hardened, is bonded with the layer of non-metallic material, and the bonded package encapsulant/the layer of non-metallic material is degatable from the mold gate.

Abstract: The present invention discloses a method of selectively oxidizing hydrogen sulfide to elemental sulfur, in which a H.sub.2 S-containing gas mixture contacts with an oxygen-containing gas at about 50-400.degree. C. in the presence of an mixed-oxide catalyst. The reaction product mixture contains substantially no sulfur dioxide. The mixed-oxide catalyst, in addition to iron (III) and molybdate (VI) components, further contains a antimony component as a promoter.
