摘要： PURPOSE:To reduced variation in the dielectric constant of the section in piping and measure a flow rate with high precision by providing a cylindrical electrode outside the piping and further arranging cylindrical electrodes at both sides of the cylindrical electrode, and covering those electrode with an electromagnetic shield plate. CONSTITUTION:The 1st, the 2nd, and the 3rd cylindrical electrodes 11, 12, and 13 are provided at the periphery of the piping 1. Further, those electrodes 11-13 are covered and shielded with the electromagnetic shield plate 14. When a high frequency voltage is applied to the 1st electrode 11, a current flows through the 2nd electrode 12 and the 3rd electrode 13. This current fluctuates with the concentration of the solid component in the piping 1 and a speed computing element 25 calculates the flow rate from the time delay at a detection part. The output when no fluid flows is found by a detector amplifying 27 and the measured detected value is corrected to calculated the flow rate in the solid component in a solid-vapor two-phase flow. For the purpose, the electromagnetic shield plate is provided to eliminate the influence of variation in the dielectric constant of the section in the piping, so the flow rate is measured with high precision.

An operator 10 calculates the emissivity of the ingot 2, the radiation energy from the surface of the ingot 2, and the radiation energy from the surface of the film on a basis of measured results. The thickness of the film 4 is calculated on a basis of these calculation results.

Ultrasonic waves radiated from the probe 10 are transmitted through a powder layer 6 and are reflected from the contacting face between a fused metal 4 and the copper plate 5 and reach the probe 10, and thus, a length L1 is obtained from a time difference T1 between radiation and detection by an operation.

摘要： PURPOSE:To measure the vibration and displacement of a body highly sensitively and a highly accurately, by constituting the system so that an input voltage to a detecting end becomes large. CONSTITUTION:The AC voltage outputted from an AC oscillator 8 is amplified by a booster circuit 9 and supplied to one of electrode plates P of the detecting end. The AD signal outputted from an amplifier 2 is converted into a DC by a full wave linear detector circuit 4. The effect of a temperature drift is eliminated by a temperature compensating circuit 5. The DC signal outputted from the detector circuit 4 is smoothed by an amplfier 6, and the electric signal corresponding to a distance (d) between the electrode P and an object to be measured is outputted. The voltage, which is approximately equal to the output voltage from the amplifier 6, is outputted from a reference voltage generator 10. The output voltage from the amplifier 6 and the output voltage from the reference voltage generator 10 are compared in a differential amplifier 7 and amplified. The infinitesimal change in the distance (d) between the electrode plate P and the object to be measured is amplified by the differential amplifier 7, and the output voltage proportional to the amount of change is obtained.

摘要： PURPOSE:To measure the distance from the position separated from a body by crossing a magnetic flux detecting coil and a magnetic field generating coil and detecting the difference between outgoing magnetic flux density and feedback magnetic flux density. CONSTITUTION:The magnetic flux generating coil 1 and the magnetic flux detecting coil 2 are provided so that they cross each other. When the coil 1 is excited by a high frequency oscillator 3 and a constant current circuit 4, the feedback loop shown by a solid line is obtained when metal is not present in the loop of magnetic lines of force phi. Under this state, balance is maintained so that an induced voltage is not generated in the coil 2. When a metallic body is present at a point A in the magnetic loop, the eddy current is generated in the body, the feedback amount is reduced, the balance collapses, and the voltage is induced in the coil 2. Said voltage has a constant relationship with respect to the distance between the coil and the metallic body, and it is outputted through an amplifier 5, a rectifier 6, and a linearizing circuit 7. Therefore, the distance can be measured at the point separated from the body, and the application fields can be expanded to the great extent.
