A strict commercial time synchronization system, method and apparatus therefore is provided. In the apparatus, a selection unit selects devices that can process the print data according to output setting information, and a generation unit generates at least one processing route for processing the print data by combining the selected devices for executing the plural processing processes. Sets of transistors are first abstracted into abstracted resources. For each event, one or more documents objectively determined to be substantially representative of the event are identified. An x-ray radiator with an x-ray tube and a housing in which the x-ray tube is contained is composed only of materials that are not suitable for absorption of x-rays. The front of the shroud is considered the leading edge, and the rear of the shroud is considered the trailing edge.
