 note = {In the electronic measuring techniques recently popularized, the relations of various measurable quantities and their outputs are generally non linear. This is not desirable, becauses of measuring accuracy, efficiency, and range. Ohm-meter is a typical example of the previous description. In order to obtain the linearly indicating ohm-meter, the nonlinear inverter circuit employing hyperbolic characteristic vacuum tube is described. This non linear inverter circuit is not only applicable on such ohm-meter, but also the other various measuring devices, for examples, electronic computer, resistance strain meter, etc., Article, 信州大学工学部紀要 5: 89-92 (1955)},
