The present invention enables the configuration of a disk array device to be changed in accordance with its purpose of use. A matrix film layer is applied to the reinforcement layer so that it does not substantially impregnate the reinforcement layer. Several process chambers that are served by a transport mechanism with holders for tissue specimens are provided for on the baseplate. Compounds of the present invention are effective ingredients for the broad spectrum of antibiotic resistance, exhibit low toxicity, particularly in Gram-negative bacteria, which can be useful with strong antimicrobial activity. The mattress assembly is supported on the folding mechanism and contains a shell and an inner support received within the shell.
