Title: Multiplex circuit
Inventor: YAMAMOTO TARO
IPC: H04J7/00
Filed: 1991-03-05
Abstract: PURPOSE:To prevent the dispersion of offset between channels for input signal levels from appearing in the output signal of a multiplexer by supplying each input signal to the multiplexer after amplifying with the same gain, and supplying the attenuation of the inverse of the gain to the output signal. CONSTITUTION:The input signals of the channels CH1-CHn are inputted to the multiplexer 1 after the amplification of the gains G are performed by an amplifier 2. At this time, for example. assuming the input signal level of the CH1 as A, an outputted signal on which prescribed time division multiplex is performed by the multiplexer 1 goes to G.A+alpha including an offset level (alpha). The output signal goes to A+alpha/G by attenuating the signal by the attenuation factor 1/G of the inverse of the gain G of the amplifier 2 by an attenuator 3, and the input signal level A can be kept as it is, however, the offset level (alpha) is compressed to 1/G. Therefore, it is possible to compress the dispersion of offset from the output signal of the multiplexer 1 relatively.

When the output of a DC tester 7 is selected, a DC voltage is applied to two terminals under the state where a motor 2 is stopped. A primary-winding resistance R1 is measured and outputted into the constant setting device 9. Finally, when the output of a single- phase tester 8 is selected, a single-phase AC voltage of 30Hz is applied to two terminals of the motor 2. The sum of the primary and secondary leaking inductances and the sum of the winding resistances are measured, and the results are outputted into the constant setting device 9. The primary leaking inductance l1, mutual inductance M and the primary and secondary winding resistances R1 and R2 are obtained and outputted into a magnetic-flux torque controller 5.
