An apparatus is configured to allocate an IDentification (ID) cell to avoid duplication of a preamble Pseudo Noise (PN) code in a broadband wireless communication system. The apparatus selects one sector inside the system. A temporary ID cell for the selected sector is selected. Whether an ID cell of a sector to which an ID cell has been already allocated inside a minimum unit group for ID cell allocation is the same as the temporary ID cell is determined. Whether PN codes of sectors inside a neighbor list of the selected sector are the same as temporary PN codes determined using the temporary ID cell are determined. When the temporary ID cell is not duplicated and the temporary PN codes are not duplicated, the selected temporary ID cell is allocated as an ID cell of the selected sector.

A color selection apparatus for a cathode ray tube. A mask frame having a pair of supporting members is disposed in parallel and spaced away from each other. A pair of elastic members is disposed between and coupled to the supporting members. A tensioned mask is coupled to the supporting members and is provided with a plurality of beam-passing apertures. A spring assembly includes a hook having a frame fixing part fixed on the mask frame and a spring fixing part and a spring fixed to the spring fixing part. The hook has a cut-away portion defined by cutting a portion of the frame fixing part. The cut-away portion forms a welding portion for welding the hook to the mask frame.
