Machine and process for the production of a tissue web that includes a drying cylinder and a press shoe arrangement. A plurality of processing handlers each associated with one of the data streams, where the handlers are processing the data of the logical data stream buffered by its stream buffer. By changing internal circuits of the control unit, a pins which connects to an energy storage element is set, therefore the lighting unit flashes in a predetermined sequence after interruption of power is resumed, and the lighting unit moves in a certain track, occurring a path in which position of light spots changed. Block compression is performed on the block if block compression is effective, but if block compression is not effective, processing other than block compression is performed on the block and at least a predetermined number of blocks subsequent to said block. During the cooling process, the foreign substrate is heated in such a way that, proceeding from the surface of the foreign substrate, the temperature continuously decreases in a vertical direction perpendicular through the semiconductor thin film to the surface of the thin film. The derailleur mount has a first mounting portion that is concentric with the pivot axis and defining a plane, a second mounting portion that is secured to the rear frame at a location spaced laterally from the plane, and a support portion.
