Title: Constant quantity controller
Inventor: YADA TETSUO
IPC: G01F13/00
Filed: 1978-07-28
Abstract: PURPOSE: To detect the malfunction of the valve opening speed of a constant quantity valve within a short time thereby to prevent the excessive quantity and the overflow accident by monitoring the varition in the flow speed after the valve closing signal is generated.  
     CONSTITUTION: When liquid supply is started by button operations, a constant quantity valve 6 is brought from its fully closed condition to its fully open condition so that flow rate pulses are fed from a flow meter 2 to a counter 1, a constant flow speed detecting unit 7 and a flow speed detecting unit 9. When the integrated flow rate reaches the supply quantity by a supply setter 3, coincidence signals are generated from a constant quantity comparing circuit 4. Under a normal condition, the model flow speed by an arithmetic unit 8 becomes coincident with the flow speed varying with the valve closing operation of the valve 6 so that no abnormal signal is generated. Under an abnormal condition, the difference between the model flow rate and the varying flow speed by the valve exceeds an allowable value so that abnormal signals are generated from a malfunction detecting circuit 10. Thus, a warning device 11 and a quick blocking valve 12 are operated.

Title: Method and apparatus for detecting finish of feed of liquefied gas
Inventor: TAKEYAMA KATSUHIKO
IPC: F17C13/02
Filed: 1988-04-15
Abstract: PURPOSE:To detect the finish of feed, by detecting the temporary lowering of temp. generated when the feed of liquefied gas is finished by measuring temp. at two places. CONSTITUTION:The feed of liquefied gas through piping 1 in the direction shown by an arrow A is started and, after a definite time is elapsed, the temp. of the piping is almost lowered to the temp. of the liquefied gas. At this time, the first and second temp. sensors 2, 3 detect signal temp. and a subtractor 6 outputs a signal showing that the difference between the detected temps. of the sensors 2, 3 is zero. When the feed is finished, the liquefied gas in a tank is lost and the gaseous mixture of the liquefied gas and compressed air enters the tank; therefore, the pressure in the piping 1 is temporarily lowered and the liquefied gas is evaporated to lower temp. Since the sensor 3 is directly mounted to the outer surface of the piping 1, the sensor 3 rapidly detects temp. change at this time but, since the sensor 2 is mounted through a copper spacer 4, the detection of the temp. change by said sensor 2 is slow. When the temporary temp. difference calculated by a subtractor 6 becomes larger than a preset value, a receiving finish signal can be emitted from a comparing operator 7.

Title: Pulse demodulating circuit
Inventor: MIYATANI SATOSHI
IPC: H03K9/08
Filed: 1991-03-29
Abstract: PURPOSE:To reduce the extension of the pulse width of a shaped waveform by constituting the smoothing circuit of an envelope detecting circuit by using a smoothing capacitor, a constant-current load circuit connected to the smoothing capacitor, and a limiter circuit. CONSTITUTION:When a modulating signal Vi for a pulse signal is supplied from an input terminal 5, the modulating signal Vi is detected by a diode 1 and then charged in the smoothing capacitor 2. When the terminal voltage for the smoothing capacitor 2 rises above the Zener voltage of a Zener diode 7, the charging current of the smoothing capacitor 2 by-passes the smoothing capacitor 2 through the diode 7 and is not charged in the capacitor 2, so that the terminal voltage for the smoothing capacitor 2 is held at the Zener voltage. When the detection output Vd of the diode 1 drops below the Zener voltage, the charges accumulated in the smoothing capacitor 2 are discharged through the constant-voltage load circuit 8. In this case, the voltage drops linearly to 0V in a relatively short time.
