Title: Gas-liquid separator
Inventor: OKI FUMIO
IPC: B01D19/00
Filed: 1979-11-19
Abstract: PURPOSE: To measure the temp. of liquid with good accuracy without increasing flow passage resistance by installing a barlike temperature sensing element coaxially to the center of the swirling flow in a gas-liquid separating tank.  
     CONSTITUTION: A gas-liquid separating tank 11 of a circular shape in section has an inflow port 12 and an outflow port 13 opening in a tangential direction, and is opened with a gas escape port 14 at its top wall; said escape port 11 is opened and closed by a float valve 15 moved vertically by the liquid level in the tank 11. A barlike temperature sensing element 10 is provided to the central axis of the tank 11, freely removably from an insertion port 1a. The temp. detected by this is transmitted to the temp. compensator of a flowmeter connected to the outflow port 13 side. In this gas-liquid separator, the formation of air layers in the central parts is prevented despite increasing the vigorousness of the swirling flow and this improves separation efficiency; in addition, accurate temp. detection is performed because the flow of fluid around the element 10 is fast.

Filed: 1988-06-17
Abstract: PURPOSE:To suppress the fluctuation of the inclination of a trapezoidal wave by generating the trapezoidal wave by a constant current without power source fluctuation and temperature fluctuation. CONSTITUTION:When a reference signal changes from an L to an H level, an output of a NAND circuit 11 changes from an J to an L, a transistor(TR) M6 is turned on, a TR M8 is turned off and a capacitor C1 is charged by a current I1. When the voltage of the capacitor C1 exceeds a voltage VH set by resistors R3 and (R4+R5), the output of a voltage comparator 1 charges from an H to an L level, a clock is inputted to a D-FF 7, the inverse of Q output of the D-FF goes to an L, the NAND circuit 11 is restored to the H level, the charging is finished and the level of the capacitor C1 is held to the VH. When the reference signal changes from H to L, the capacitor C1 is held as the voltage VL as it is. Thus, the potential of the capacitor C1 is changed in a trapezoidal waveform by a constant current with no power source fluctuation and temperature fluctuation charateristic, and a stable output is obtained via a voltage follower circuit 13.
