Patent JP-S5733365-A (JP)
Title: Phase meter
Inventor: ABE SHIGERU
IPC: G01R25/08
Filed: 1980-08-05
Abstract: PURPOSE:To measure a phase difference with virtually no time lag by using a circuit which digitally measures zero cross time difference at every cycle, and outputs the same after subjecting to the digital to analog conversion. CONSTITUTION:Period signals e1, e2 having the two same frequencies are applied respectively to a zero cross circuit 1 and an FF2, and the square wave e5 having the pulse width proportional to a zero cross time difference is formed. This is applied to a modulated wave generating circuit consisting of an AND gate 4 and a clock generating circuit 7, whereby a signal e8 is obtained. Next, a microprocessor 8 supplied with the signal e8 operates phase differences based on modulation quantity. It is next converted 9 from digital to analog to form a staircaselike signal e10 which is outputted. In this way, the phase difference between the period signals e1, e2 is outputted with a time lag of only the processing time TD. Hence, the phase difference is measured with virtually no time lag.

Title: Measuring unit of flow rate
Inventor: NAKANO HISAO
IPC: G01F1/698
Filed: 1979-08-24
Abstract: PURPOSE: To achieve simplified unit, by keeping the temperature difference between the temperature of fluid and that of heated fluid at a constant value, and converting the quantity of energy required for heating into the flow rate of fluid.  
     CONSTITUTION: Fluid flows toward the arrow direction of A in the pipe 1. The temperature of fluid is detected at the fluid temperature detector 2, the heater 3 which has a shape not disturbing the flow with a flat shape at understream and the fluid is heated and detected for the temperature at the detector of heating temperature 5. In this case, the power quantity fed to the heater 3 is controlled to keep the temperature difference by the detectors 2 and 5 at a constant value and the flow rate can be measured by using the function generator which converts the power quantity fed to the heater into the flow rate. Even in case of the pipe 1 of a large diameter, large sized detectors as conventional are not required and the entire unit can be simplified.

Abstract: PURPOSE:To discharge cooling water staying in a piping out quickly before freezing by a method wherein the freezing condition of the cooling water is detected and a compressed gas is introduced into the cooling-water piping. CONSTITUTION:When the flow speed of cooling water flowing in a cooling water piping 5' attached to a normal conducting coil 4 is declined and the flow is practically stopped, a current meter 13 outputs a flow speed detection signal. When the temperature of the cooling water is declined to reach a freezing temperature, a thermodetector 14 outputs a temperature detection signal. The first and the second judging elements 15 and 16 control the flow stop and the temperature decline of the cooling water. A logic discriminating circuit 17 discriminates the necessity o discharging the cooling water and supplying a gas in accordance with the logic condition of a flow-speed judging signal and a temperature-judging signal and outputs an instruction signal to a driving circuit 18. The circuit of a cooling-water piping system consists of the linking passage of a gas supply apparatus 12   a control valve 10   a cooling water piping 5'   a control valve 11   the outside. A compressed gas is introduced into the piping 5' with pressure and the cooling water is discharged through the control valve 11 so that a breakdown of the cooling-water piping 5' or the like can be avoided.
