A plastic mounting plate closes a electrical box which delivers wires to an alarm unit or emergency light or the like. An optical fiber is formed having a tubular cladding of a first polymeric or glass composition having a first index of refraction, wherein the cladding has a longitudinal axis. The bra cups’ breast side rests against the inner form’s exterior surfaces to prevent it and the bra’s underwires from losing their natural curvature. The TFT and the storage capacitor has a semiconductor layer which includes first and second regions formed continuously. The first mounting structure includes an installation member, and a locking member slidably installed in the installation member.
