Abstract: Provided is an overcurrent protection circuit including an overcurrent detection unit configured to compare an output current flowing through a switch element and a predetermined overcurrent detection value to generate an overcurrent detection signal, an output activation detection unit configured to compare an output voltage and a predetermined threshold voltage to generate an output activation detection signal, a logic unit configured to combine the overcurrent detection signal and the output activation detection signal to generate a logic operation signal, and a diagnostic output unit configured to provide diagnostic output, the logic unit shifting the logic operation signal to a logic level of abnormal state when the overcurrent detection signal is shifted to a logic level of overcurrent detection state and holding the logic operation signal at that logic level, unless the output activation detection signal is shifted to a logic level of output activation state.

Abstract: A tensile force is applied to at least a surface of a film to which a conductive material is applied within an elastic limit by a tensile force applying means, the conductive material is applied to a first surface of the film by a coating means in a tensioned state, and thereafter the tensile force is released by a tensile force releasing means to form the film having a conductive sheet for a touch-panel. Preferably, the tensile force applying means is a barrel-shaped roller.
