Abstract: The instant trip apparatus of the molded case circuit breaker includes a case, a magnet part disposed in the case to generate magnetic attractive force when accident current flows therethrough, an armature disposed to face the magnet part, the armature rotating to the magnet part by the magnetic attractive force, an armature spring for allowing the armature to elastically return to its original position when the magnetic attractive force is removed, and a gap maintenance part restricting the rotation of the armature so that a gap defined between the armature and the magnet part is maintained when the accident current occurs. The gap maintenance part includes a rotation restriction member that is disposed to be exposed to an armature rotation path between the armature and the magnet part. Thus, fusion between the armature and the magnet part due to the accident current occurs may be prevented.

Abstract: Provided are a method and apparatus for user equipment (UE) selection in a mobile communication system. The method may include: selecting the n?1th UE in multiple cells (n: constant ?2); and selecting a UE with the maximum weighted sum rate (WSR) as the nth UE from among UEs belonging to the remaining cells excluding those cells containing the 1st to n?1th UEs. Hence, the scheduling function enabling suitable user equipment selection may further increase overall system throughput by providing additional gains in addition to beamforming, i.e. further reducing inter-cell interference and increasing signal strength toward a desired user equipment.
