A circuit for protecting a plurality of tipring SLIC cards during over current or over voltage conditions. The energy unit is driven to eject the ejection medium from the nozzle in a droplet form. The additive compounds added to the electrolyte of the present invention decompose earlier than the organic solvent to form a conductive polymer layer on the surface of a positive electrode by increased electrochemical energy and heat at overcharge. Prior to segmenting, the framing unit surrounds a partial region of the display region of the display unit. The first and second field coils are connected substantially in parallel to each other when viewed from an external field current supply source supplying field currents to the first and second field coils.
