System, including apparatus and method, for processing a material involves automatically printing labels for pieces cut pursuant to a cut list. An air outlet for an air discharge in a spring chamber of the switch body is formed inside the connector and air is discharged trough the interior of the connector and a wire core. Shapes of ink droplets deposited by the nozzles on the substrate, to form the protective layer, are controlled by shapes of electric waveforms applied to the actuators. The input complete data memorizing means is capable of maintaining the memory content even when the vehicle is stationary. This back-filling process is accompanied by a regeneration of the surface plasmon bands in the UV-visible spectrum.
