This invention provides a support for photographic paper being excellent in whiteness and flatness and inexpensive, and having a sufficient adhesive strength of resin which can be generated even at a low resin temperature of 200 to 280 C. The system includes a pressure generator that generates a pressurized flow of breathable gas and a circuit that communicates the pressurized flow of breathable gas from the pressure generator to the airway of the subject. A second bias circuit is operable to set a common mode voltage of the second amplifier. The cable guide and the cablewires may be secured in a fixture that allows the wire ends to be repeatably scored to remove insulation. It is therefore possible to prevent an outflow of illegal data from a storage subsystem to be caused by an active copy instruction command. The data model allows for modeling of all information relating to a computer network to be conveniently stored in a database in a manner which minimizes the effort associated with the addition of new devices to the network and maximizes software code reuse.
