Abstract: The present invention concerns a process for removing carbon monoxide and/or gaseous sulphur compounds from hydrogen gas and/or aliphatic hydrocarbons, preferably at low temperatures, with the aid of complex metal aluminium hydrides.

Abstract: The present disclosure relates to a positive electrode active material for rechargeable lithium ion batteries and a method of preparing the positive electrode active material, in which a compound including sulfur is used as an additive in a wet treatment process to remove residual lithium impurities (LiOH, Li2CO3) present on a surface of the positive electrode active material, such that the residual lithium impurities are effectively removed without loss of capacity while a Li-S compound coating layer is formed on the surface thereof, thereby reducing resistance and leakage current.

Abstract: Disclosed herein is an identifier based communication system including: a common communication path; a center station having a center station communication module and a center station controller connected to the center station communication module and connected to the common communication path through the center station communication module; and a plurality of distribution stations each including a distribution station communication module connected to the common communication path, a distribution station controller connected to the distribution station communication module, and a distribution station memory connected to the distribution station controller and storing a determined identifier value of the distribution station, wherein the center station controller transmits an identifier setting mode command including a center transmission preliminary identifier value to the distribution stations following an identifier setting request input from the outside; each of the distribution stations includes a distri

Abstract: The light emitting diode assembly for an illuminated sign is disclosed having an enhanced waterproofs function and an enhanced durability. The light emitting diode assembly includes a case being open upwards, in which a connecting recess is formed on upper portions of both sides of the case. A printed circuit board is installed in the case and being mounted on upper sides of a plurality of light emitting diodes. The hollow cap is coupled in the connecting recess of the case, in which a plurality of wires passes through the cap. A synthetic resin material for covering the printed circuit board, the cap and the light emitting diode, is filled in the case. In this structure, the light emitting diode assembly can prevent the printed circuit board, transformer and the light emitting diode from being damaged by using an epoxy resin.
