An ice resurfacing machine for small and medium-size indoor and outdoor ice skating rinks comprises a light towing vehicle, a resurfacing attachment, and a lifting and leveling assembly connecting them. The first low-voltage rated transistor and the first high-voltage rated transistor may be connected in series, and the second low-voltage rated transistor and the second high-voltage rated transistor may be connected in parallel. It can be used in hospitals or at home. When the holding container is closed by means of the closure member with the coating tool stored in the holding container, the handle of the coating tool projects outward through the opening. In addition, the method may include forming channel dopant regions within the wells of opposite conductivity type.
