An individual sheet overlapping mechanism includes holding cylinders having paper edge holding mechanisms capable of holding a front edge portion in a conveying direction of a first individual sheet and that are provided rotatably along the conveying direction of the first individual sheet. A first master clock resides on the primary router matrix card of a first chassis while a second master clock resides on the redundant router matrix card of a second chassis. A semantic file network may further be constructed based on similarities between files that are based on the semantic attribute information. A numeric display area may be provided adjacent the graphic display area to display the actual vertical and horizontal timing differences in appropriate units for the emphasized timing indicator relative to the reference indicator with a precision to one video clock cycle. As a result, a combined movement at the distal end of the catheter can be produced particularly simply for compression and release of a functional element. The thermosetting composition may be in liquid, powder, or dispersed form and may be applied by traditional or electrocoating methods.
