A method of forming a corrugated capacitor on a semiconductor component. The log management unit manages a job log indicating a history of a job executed by an image forming apparatus, a log image indicating a history of an output image serving as an output target of the image forming apparatus for the job, and an operation log indicating a history of an operation input to an operation unit in the image forming apparatus for the job. The shaft is connected to the first holder and the second holder for receiving thrust caused by the thrust mechanism. The system further uses database information to internally route messages to message processing programs which process messages and generate messages to the external devices and authorization systems.
