By employing a 1% potassium-added cobalt catalyst prepared by adding potassium to cobalt as a catalyst for depositing carbon from mixed gas containing a carbon source, it was possible to lower the optimum catalyst temperature from 510-520 C. The nozzle arrangement includes a substrate assembly, in turn, including an electrical drive circuitry layer and defining an ink inlet channel. The device includes the contactless reader for reading information stored in the contactless label chipcard, and a component for generating an invoice based on the information received from the contactless label chipcard. This makes it possible to drive linear amplifiers dB-linearly.
