Title: Detecting circuit of impedance change
Inventor: FUJII TOORU
IPC: G01R19/10
Filed: 1980-04-02
Abstract: PURPOSE:To detect the change of an impedance by connecting two impedance elements in series, applying an AC signal having a certain amplitude, taking out said signal changing-over the voltage at both ends of said two elements with a certain period, and detecting the difference thereof. CONSTITUTION:A differential capacitance type sensor C is constituted by fixed electrodes SP1 and SP2 and a movable electrode MP. At both ends of electrostatic capacities C1 and C2, an AC signal having certain amplitudes (e) is applied from a signal source SG. Terminal voltages of said electrostatic capacities C1 and C2 are taken out alternately by switching over a switch SW with a given period. The taken-out voltage is converted to a low impedance output with an operating amplifier A1 and provided to a detecting circuit DT. The output of said DT is provided to an extract circuit DE, where an output of a capacitor C4 becomes a voltage corresponding to a difference of peak values e1 and e2, or a difference of values C1 and C2 by charging the DC voltage corresponding to the peak value e2 to the capacitor C4 when Q3 is on and providing the AC voltage corresponding to the peak value e1 to said capacitor C4 when Q3 is off.

Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To provide an air bubble separator for the microgravitational environment which responds to the situation when flow rate fluctuation of a gas-liquid mixed solution introduced into a separation barrel becomes large. SOLUTION: The air bubble separator is constituted of three units consisting of an introduction pipe unit 1 equipped with an introduction pipe for introducing a gas-liquid mixed solution flowing through the inside of a loop, a separation barrel unit 2 equipped with a separation barrel 9 in which the gas-liquid mixed liquid introduced from the introduction pipe is allowed to flow as a spiral flow and a separation membrane unit 3 freely detachably fitted to the axial center part of the separation barrel 9. These respective units are freely replaced respectively. Thereby, since only the unit having optimum inflow bore diameter and the inside diameter is rapidly replaced, correspondence is rapidly enabled even if flow rate fluctuation of the gas-liquid mixed solution introduced into the separation barrel 9 becomes large.
