An adhesive material comprises a polymeric component, a heat conductive filler and a curing agent. An operating unit is connected via a data line with the printing unit. The information displayed by the display devices is controlled as a function of actuation of the command unit andor the parameter sensor. The continuous portion is larger in thickness than the metal plate. In this embodiment, the memory controller is configured to selectively insert one or more idle clock cycles between a first memory access and a second memory access depending upon the detected power condition. Electric flashovers between the regions of the current path that are in contact with the electrically conducting piece are prevented by an electrically insulating material .
