摘要： In a constant current circuit, a constant current is caused to flow through a resistor, thereby causing a constant voltage to occur across the resistor. This constant voltage is then superimposed on an output signal of an operational amplifier that is to be fed back to the drain of a field effect transistor, thereby maintaining the same potential in an AC manner between the output terminal of the operational amplifier and the drain of the field effect transistor. In this way, the gate and drain of the field effect transistor is caused to exhibit the same potential in an AC manner, so that no current will occur through the stray capacitance between the gate and drain of the field effect transistor. As a result, similarly to a case of using a feedback capacitor, the input impedance of the field effect transistor can be raised.

摘要： An electromagnetic flowmeter includes a coil, exciting section, noise eliminating section, and arithmetic processing section. The coil applies a magnetic field to a fluid flowing in a pipe line. The exciting section supplies an exciting current to the coil. The noise eliminating section eliminates noise from a measurement signal detected from the fluid under excitation by using a differential frequency component between a commercial power frequency and an exciting frequency. The arithmetic processing section calculates a measurement flow rate on the basis of the measurement signal output from the noise eliminating section.

摘要： A voltage/current converting circuit is provided in a stage prior to a communication circuit. An over-current preventing circuit is incorporated into the voltage/current converting circuit. The voltage/current converting circuit converts a DC voltage signal into a DC electric current signal, and converts an AC voltage signal into an AC electric current signal. Moreover, the voltage/current converting circuit keeps the excessively large electric current that would flow into the internal circuitry thereof to no more than a predetermined electric current value (for example, no more than 30 mA) when the positioner is connected in error to the voltage source side without a load resistance connected.

摘要： The present invention related to a method for joining ceramic members and an insertion member to be employed in the joining method. In the present invention, ceramic members are heated by the induction heating in a state that a heating ceramic member having a conductivity larger than those of the ceramic members to be jointed is intervened between the ceramic members to be jointed. In this induction heating, the heating ceramic member having a larger conductivity is mainly heated and the temperature of the butting portion is raised up to a temperature needed to join the ceramic members. Upon joining the ceramic members, it is desirable to press the butting portion but is not necessarily needed. In the case without the pressing, it is desirable to form a layer of a joining agent on each of the butting surfaces of the heating insertion member beforehand.
