摘要： A glucose sensor system comprising the steps of using as a sample discriminating parameter a ratio (I/ΔI) of a measured current value I to the time-differential value of the current value ΔI, defining a discrimination function that discriminates whether a sample is blood or control fluid and uses the discriminating parameter as an independent variable, quantitating as a discriminating index a numeric value obtained by substituting a discriminating parameter value into this discrimination function, and automatically discriminating, based on this index, whether the sample is blood or a control fluid, whereby a kind of the sample can be automatically quantitated by measuring electric current when a sensor system is used for quantitating the concentration of an analysis object in the sample.

摘要： Video tape recording apparatus with means for editing the recorded material without significant sudden change in current to the capstan motor. During recording of the added or replacement material the capstan motor is controlled by comparing the phase of a fixed high frequency signal with a signal generated synchronously with rotation of the capstan motor. The fixed frequency signal can be generated by a stable oscillator or by using submultiples of fixed-frequency components of the video signal.

摘要： A predetermined voltage is applied to a biosensor twice to promote an electrochemical reaction, and the following parameters (P1 and P2) are calculated from the values of detected current. A statistical technique is used with these parameters to compensate for errors so that the concentration of an object can be determined. P1: the ratio (If/Ib) of the maximum current (If) or a current occurring the maximum in the first excitation to a current (Ib) read at any point in the second excitation. P2: a current (Ib) read at any point in the second excitation.
