摘要： PROBLEM TO BE SOLVED: To measure the volume even of an incomplete closed space highly accurately by adding a space having a plurality of set volumes to a closed space and measuring the pressure in the closed space respectively and then determining the volume of closed space based on each measurement. SOLUTION: An actuator control section 9 controls an electromagnetic actuator 2 to oscillate a pressure piston 3 at a specified frequency and stroke. Volume variation dependent on the product of cross-sectional area at the hollow section of a cylinder 7 ×stroke causes pressure variation in a container 11 to be measured. A processing section 10 fetches a pressure signal from a pressure sensor 4 and determines the average pressure variation over a plurality of periods which is employed, along with the volume variation of cylinder 7, for determining the volume of container 11. The measurement is repeated three times while varying the stroke and the processing section 10 interpolates three measurements linearly. The volume for 0 stroke is then determined according to an interpolated line when the volumetric variation of cylinder 7 is zero, i.e., when the fluid is not leaked, and the volume thus determined is outputted to a display or the like.

摘要： PURPOSE:To detect the abnormality of external size at high speed with high accuracy by monitoring the movement of a diffraction pattern due to the fluctuation of the external size of a specimen by a pair of photosensors. CONSTITUTION:When laser beams 31 are formed into a parallel luminous flux by a lens 32 and converged by a lens 33, the diffraction pattern 30 of a wire rod 2 as a specimen arranged between the two lenses 32, 33 is observed on a detecting surface 34, and the direction of the expansion of the pattern 30 crosses at a right angle with the direction of the extension of the wire rod 2. Two pairs of photosensors 41 consisting of photosensors 41a, 41b are arranged at places, where for example primary diffracted light in a specified order is received in the pattern 30 on a substrate 40 disposed on the detecting surface 34 at that time. Consequently, the sensors 41a, 41b mutually receive the primary diffracted light by the same quantity of light when the wire rod 2 has size in conformity with the stipulations. When the wire rod 2 has thicker (thinner) than the stipulations, light having the larger quantity of light is projected to the sensor 41a,(41b). Accordingly, the difference of the light-receiving signals of the sensors 41a, and 41b, is arithmetically operated, thus detecting the normality and abnormality of the external size of the wire rod 2.

摘要： PURPOSE:To measure a flow with high response and a low loss without being affected by the viscosity, temperature, and flow velocity of a fluid by branching the fluid in a measuring object tube into laminar flows having the critical Reynolds number or below respectively. CONSTITUTION:A laminar flow tube 11 is bundled with multiple fine tubes 11-i having the inner diameter of the critical Reynolds number or below respectively to branch a fluid in a measuring object tube into laminar flows. At least one of the fine tubes 11-i is made transparent for the flow measurement by a laser Doppler flowmeter (LDV). Rectifiers 12A, 12B are arranged on both sides of the laminar tube 11 to rectify the disturbance of the flow velocity distribution at the front and rear of the laminar tube 11. The LDV is constituted of an LDV probe 131, a lens 132, a reflector 133, and an optical fiber, and the flow velocity at one point of one transparent fine tube 11-i of the laminar tube 11 is measured. The output of the LDV is connected to a flow arithmetic unit 14, and the flow is calculated based on the flow velocity, cross sectional area, and number of the fine tubes 11-i.

CONSTITUTION:When the liquid in a measured injection quantity DELTAV is injected into the first sealed container 21 from an injection nozzle 24, the pressure in the container 21 increases, and a diaphragm 23 is pressed, and displaced by DELTAL into the second sealed container 22, and this displacement is detected by a noncontact type gap sensor 25. The detection displacement signal is inputted into a measurement calculation device, and the fuel injection quantity DELTAV and the fuel injection rate are calculated on the basis of the displacement quantity DELTAL and the displacement time (t) of the diaphragm 23 which are obtained from the detection displacement signal. At this time, the fuel injection quantity DELTAV is calculated on the basis of each capacity of the first and second chambers 21 and 22, effective area of the diaphragm 23, and the displacement quantity DELTAL, and the fuel injection rate is calculated according to the above-described elements and the density of fuel, and can be obtained independently of the volume modulus as the function of fuel temperature, pressure, kind, etc.
