Abstract: A subordinate server creates an event notice list, that is a list of the stored electronic document files having a high use frequency, and copies it onto a host server such that the host server holds it on a subordinate server-by-server basis. When an electronic document file is changed in a certain subordinate server, the subordinate server copies the changed electronic document file onto the host server, and at the same time, checks if the changed document file is present on an event notice list of another subordinate server held by the host server, and notifies a change event to the other subordinate server for storing it on a change history list, only when the file is present. If the subordinate server is requested for looking up an electronic document file, and the requested electronic document file is present on the change history list, the subordinate server copies the corresponding electronic document file from the host server for allowing the requester to look up.

Abstract: A part mounting device is provided for mounting a front end module onto a vehicle body. The device comprises a frame structure vertically movably mounted on a carry truck through a lifter, a holding device capable of holding the front end module onto the frame structure, a positioning bar slidably disposed on the frame structure, and an actuator capable of moving the positioning bar on the frame structure. Positioning pins are movably held on both ends of the positioning bar and engageable with positioning openings formed in a front end of the vehicle body.
