摘要: An improved ZnS blue light emitting device is formed with a low-resistivity ZnS layer serving as a luminescent layer, a high-resistivity insulating layer of multi-layer structure for hole carrying injection above the low-resistivity ZnS layer and an electrode on the high-resistivity insulating layer. The high-resistivity insulating layer includes at least two stacked layers of different insulator materials serving different functions.

摘要: An apparatus for protecting coal mine workers from flying coal, rocks, coal dust, scattering coal and the like, which are produced as a drum shearer works in a longwall coal face. The apparatus is provided with isolated walls or chambers between iron props installed in the self-advancing supports provided in the longwall coal face by use of fastening members. The isolated wall or chamber is connected with its adjacent wall or chamber by a flexible connecting member.
