Abstract: An information processing apparatus transmits, by polling, a status verifying message to a disk array apparatus to verify a status of the disk array apparatus. The disk array apparatus attaches, upon receiving the status verifying message, a request for a command of a process to be executed to a response message to the status verifying message, and transmits the response message to the information processing apparatus. The information processing apparatus creates a command based on the request attached to the response message, and transmits the command created to the disk array apparatus.

Abstract: The present invention prevents a lowering of the baking quality of a baked product due to a variation in the temperature distribution in a baking furnace due to the inflow of air into the baking furnace. A baking furnace has an inlet disposed in a clean room and an outlet disposed in a normal pressure room lower in pressure than the clean room. The baking furnace is provided with a differential pressure gauge, a controller, an inverter, and an exhaust fan installed in a return duct, the arrangement being such that the difference in pressure between the clean room and the normal pressure room is detected by the differential pressure gauge and the operation of the exhaust fan is controlled by the controller according to the detected differential pressure, so that the air flowed in through the inlet is discharged through the return duct. Thus, the air is prevented from flowing into the baking furnace.
