  • Patent number: 8610017
    Abstract: In a capacitive input switch that is accommodated in a housing of electronic equipment, the capacitive input switch includes a rigidity imparting layer having rigidity and a laminate sheet laminated on the rigidity imparting layer. The rigidity imparting layer and the laminate sheet are three dimensionally formed. The laminate sheet is formed by a substrate sheet, a conductive pattern layer for capacitor formation, and a decorative layer that is laminated at least on any one of the substrate sheet and the conductive pattern layer. A separate conductor is caused to contact with the conductive pattern layer and the conductive pattern layer is caused to be electrically connected to an external electric circuit by the conductor.

  • Patent number: 4985672
    Abstract: In equipment which measures current of ICs for testing them, there are provided a first current detector for detecting current which flows through an IC under test when applying voltage from a voltage source to a power source terminal of the IC to which a smoothing capacitor is connected, a buffer amplifier for extracting the voltage to be applied to the power source terminal, a compensating capacitor which is supplied with the output of the buffer amplifier and provides a charging/discharging current equivalent to that which flows through the smoothing capacitor, a second current detector for detecting the charging/discharging current of the compensating capacitor, and a subtractor for subtracting the output of the second current detector from the output of the first current detector.
