A wipe that includes a bacteriostatic agent that contains cations having an affinity for the negatively charged cell walls of bacteria is provided. User information corresponding to a user is encrypted or decrypted using the cryptographic key. The first or second wave retarder is configured to be linearly translatable relative to the other wave retarder. The incoming air flow is protected from heat exchange with hot reformate exiting the catalyst, allowing for convective cooling of the catalyst side and greater cooling of the catalyst face, thus increasing the working life of the catalyst while providing for rapid startup of the reformer and associated fuel cell system. The exposure control unit controls an exposure condition of the exposing unit for each of the small work areas and allows the exposure to be performed collectively on multiple layers’ worth of the photo-curable resin in a predetermined one of the small work areas.
