This invention is directed to super-absorbent material, which comprises a super absorbent polymer core that is coated with an organic, polar coating agent, and whereby the particulate super-absorbent material has a contact angle and a corresponding cos CAm, whereby the cos CAm is more than 0. At least one of the first and second chips includes a high voltage generator configured to receive an input voltage through the common inputoutput pad and generate a test voltage responsive to a test mode signal during a test mode of operation. In one embodiment of the invention, the antibiotic is an isothiourea compound, which may comprise a polyhalogenated benzyl group, e. Switching circuitry for connecting the light emitters and detectors in a switching matrix has a plurality of matrix rows and matrix columns. The discharge is non-thermal and operates near room temperature and has an intense optical emission. When the paper IDs do not coincide with each other or when the paper ID cannot be acquired, the controller causes an NG recording unit to perform NG recording on the paper and causes a paper-conveying-path switching unit to switch a discharge destination of the paper to a garbage tray and discharge the paper.
