The electromagnetic coil according to the invention has a coil core, a winding of coil wire and two contact pins, the contact pins being secured to at least one resilient holding member and being movable relative to the coil core. In one embodiment of the present invention, the gaming device provides a plurality of adjacent player selectable selections. Design modifications of dehumidifiers include separation of cooling and water condensation components from other components that radiate heat to enhance the cooling effects of dry air leaving the dehumidifiers. A shutter is provided to shield the substrate member as the hot graphite rod assembly is heating up. Coupled to the check circuit, the control unit is configured to cause reexecution of the first instruction responsive to the error detected by the check circuit.
