A heat-resistant pipe is arranged so as to traverse below a glass ribbon in a float bath of molten tin, and bubbles emanate from the heat-resistant pipe, thereby making the bottom surface uneven. Each receptacle body has an axis, first and second end portions, and a peripheral wall that is disposed to surround the axis so as to define a receiving chamber. The access terminal is identified by one of a plurality of mode-dependent identifiers in communication over an air interface between the access terminal and the network.
