Disclosed are various exemplary embodiments of apparatus, methods and memory medium storing computer program instructions for both a base station and a user equipment. The computer body includes a language information-providing section adapted to provide the display device with information about the kind of language used in the operating system. After an elapse of a preset equalization processing time period, discharge of all the battery cells is stopped. The side plate has a first planar portion which includes the first rear edge and a second planar portion which includes the second rear edge. The first hard mask is etched using the spacers and the dummy pattern as an etch barrier layer to form a first hard mask pattern. A docking collar with male projections extending laterally therefrom is associated with one of the first and second barrel portions, and for each male projection, at least one complementary track is provided in a track-carrying member associated with the other of the first and second barrel portions.
