An access device includes means for receiving, via a wireless communication link, a key and validity information. In a first chamber, hexamethyldisilazane is supplied onto the surface of the underlying film while annealing the substrate, so as to form a first molecular layer of trimethylsilyl groups on the underlying film. The display panel is provided with a triangular protrusion along rear edge, and the control panel is provided with a recess for receiving the protrusion. Also, in the defect management method, when an area that has already been linearly replaced is allocated as a supplementary spare area, defective blocks within the allocated supplementary spare area are not used for linear replacement, and the entries of a secondary defect list with respect to the defective blocks are not changed. Such plausible activities and safety of the present peptide enable advantageously to application to drugs, quasi-drugs and cosmetics.
