A light emitting device includes a micro-reflection structure carrier, which is formed by performing etching process on a carrier, a reflection layer, a light emitting layer, and a transparent adhesive layer, wherein the reflection layer is formed over the micro-reflection structure carrier and adheres to the light emitting layer through the transparent adhesive layer. The imaging lens has a quality image stabilizing system in which a light-weight lens piece is moved in directions perpendicular to the optical axis. The system includes the UE and the microblog server. Substitutionally doped Si-containing films may be selectively deposited onto the crystalline surfaces of mixed substrates by introducing an etchant gas during deposition. The packet repeater machine of the present invention executes processing for switching addresses as a part of packet relay processing.
