The present invention deals with the electrochemical synthesis of electrically conductive polymers in supercritical fluids, for example supercritical CO2. Lateral air intakes include each one a scoop movable between a closed position and an opened position are associated with aerodynamic channels to supply with air the auxiliary jet engine. Since the conductive layers having opposite polarities are engaged to each other with the non-conductive gap therebetween, the flow of current is increased and the resistance of the thermistor is decreased. A batch is given a distinct number to identify the data. after beginning to put the image forming device on the market. The DVD drive plays a DVD, wherein the DVD includes video content.
