摘要： The present invention has for its object to provide a bias circuit capable of handling multiple frequency bands, which has a low number of parts and can be miniaturized. As a solving means therefor, the bias circuit of the present invention comprises: a first reactance means 2 and a second reactance means 5, one end each of which is connected to a bias point 210 to which an alternating current signal is supplied; a capacitive means 3 connecting the other end of first reactance means 2; and a direct-current circuit 4 supplying a direct-current bias signal to the connection point of first reactance means 2 and capacitive means 3. Then, the reactance values of first and second reactance means 2, 5 have been set so as to make the combined admittance, seen from the alternating current signal supply point toward the side of first reactance element 2 and second reactance element 5, zero.

摘要： An odor sensing system is comprised of a sensor cell including a plurality of quartz resonator sensors aligned therein to detect odor by variation of resonance frequencies derived from weight loading on surfaces thereof, a recognition line including a neural network which recognizes data obtained by subtraction between an output signal of the sensor as frequency variation and, a reference signal selected by one of the output signals of the sensor. The sensor cell is thermostatically regulated by circulating thermostatic water therein to maintain the temperature higher than an advance line of the system. A sample to be recognized is supplied to the sensor cell in a form of vapor generated by blowing a standard gas onto the surface of the sample.
