Matsushita Electric Industrial, Kyoto Daiichi Kagaku, November 30, 1993: US05266179 (788 worldwide citation)

A sensor 13 is inserted into a connector 14. A constant voltage required to obtain a response current is applied across the connector 14 by a voltage applying source 15 at timings required. A response current of the sensor 13 inserted into the connector 14 is converted into a voltage by a current-to ...
