An optical switching apparatus includes an optical switch having a plurality of input ports and output ports, optical amplifiers, monitor circuits, optical amplifiers monitor circuits, and a controller that controls the optical switch. The coating 10 comprises a self-levelling, self-curing epoxy resin primer adhesive 14, an adhesive modified epoxy resin binder adhesive 16 and granulated Copper Nickel alloy 18. 0, in which an image formed on a conjugate plane on the reduction side is magnified and projected onto a conjugate plane on the magnification side. The taken image display control means displays a taken image on the display screen, and changes a taken image to be displayed between before and after closing and opening the information processing apparatus when the information processing apparatus is closed and opened again. An air compressor provides the air to the air ejection tubes of the mold housings. A communication processing device executes communication processes with the RFID tag, exchanging commands and responses, and a data creating device creates safety data indicative of a margin of safety of communication based on communication results by the communication processing device.
