摘要： PURPOSE:To prevent the deterioration of the measuring accuracy even when the width of an object to-be-measured is changed by using a calibrating apparatus which has measuring elements for calibration of the width provided in pairs at the equal distance right and left from the center and, a shutting means for shutting the light between each pair. CONSTITUTION:Two detectors each having a built-in linear sensor are set via a gap. The calibrating apparatus has pairs of measuring elements E1-E5 for calibration of the width at the equal distance right and left from the center of a base plate 10. The distance or width of each pair E2-E5 is realized by covering the pair and shutting the light by the respective step F2-F5 provided in a cover plate 12. The center of each pair is agreed with the center of the two detectors, and the right-and-left direction is made coincident with the distance direction of the detectors. A calibrating coefficient for the distance of each pair is obtained from the difference between a true value of the distance and the measuring data of the distance by the detectors. The width of the object is corrected by selecting a correcting coefficient based on the range of the unprocessed data of the detectors, and accordingly the measuring accuracy is improved.

摘要： PURPOSE:To enable accurate measurement of various dimensions of a hot billet on line at a high speed by arranging first and second outer-diameter measuring devices integral so that diameters to be measured are perpendicular to each other. CONSTITUTION:In order to measure a diameter of a section of a hot billet 10 vertical to a direction A of conveying thereof, first and second outer diameter measuring devices each provided with light projecting sections 22 and 22' and light receiving sections 24 and 24' for parallel light beams are arranged integral that the diameters to be measured of the billets are orthogonal to each other. A driving means 30 turns the first and second outer diameter measuring devices in a range of at least 90 deg., preferably, 100 deg. on the center axis of the billet 10 so that measuring devices 22 and 24 are oscillated in a measurable range of at least diameter 50 and diameter 50' while measuring devices 22' and 24' are oscillated in a measurable range of at least diameter 50' and diameter 50. In addition, a signal analysis computing means 32 analyzes signals from the first and second outer diameter measuring devices being oscillated to calculate various dimensions of the billet 10 from minimal and maximal values thereof.

摘要： PURPOSE:To calibrate the beam path length between probes and the base point of measurement of probe intervals easily and securely by allowing computing elements to detect the beam path length and the reference calibration value of the distance between the probes from the measured angle of refraction of the probes and the plate thickness of a reference body to be inspected. CONSTITUTION:The reference value computing elements 8 and 13 calculates the reference distance of transmission of an ultrasonic wave V in a body to be inspected and the reference beam path length from the measured angle of refraction of the probes and the plate tickness of a reference body to be inspected. Then a reference calibration value computing element 12 calculates the reference calibration value of the distance between the probes from the difference between the output of an inter-probe distance detector 11 which detects the distance between the probes 2 and 3 for transmission and reception and the output of a reference computing element 13 for the transmission of the ultrasonic wave V. Then, a reference calibration value computing element 7 calculates the reference calibration value of the beam path length between the probes from the difference between the output of a beam path length detectot 6 which is found by an acoustic speed from a flaw detector and the output of a reference value computing element 8 for the transmission of the ultrasonic wave V. Consequently, the position of the incident point of the body to be inspected and variance in beam path length as to each probe are corrected while the probes are mounted.

摘要： PURPOSE:To reduce the region where flaw detection of a steel sheet edge part is not performed, by deflecting incident angles of left and right vibrators in divided type vertical probe, and transmitting ultrasonic beam to the edge part side. CONSTITUTION:A sound dividing surface 5 of the probe 2 is placed parallel to the steel sheet edge 8 and as near as possible to the steel sheet edge 8, and the probe 2 is scanned in a direction 9. Ultrasonic incident angles of a transmitting vibrator 3 and a detecting vibrator 3a are regulated to different angles respectively, and the beam propagating positions are deflected to the edge part 8 side. By reducing a nonsensible band 11 of the part 8, the region where flaw detection is not performed in the part 8 is reduced.

摘要： PURPOSE:To give a desired flow rate to all branch pipes and at the same time to avoid the waste of energy, by obtaining the pressure necessary for giving a desired flow rate to each branch pipe and then controlling the pressure of a main pipe to the maximum level of pressure of the branch pipe. CONSTITUTION:The pressure necessary for giving a desired flow rate to each branch pipe is obtained, and the pressure of a main pipe is controlled to the maximum level of the obtained pressure for the branch pipe. For instance, the flow rates of branch pipes 1-4 are controlled to V1, V2, V3 and V4 by flow rate controllers 11, 21, 31 and 41 and flow rate controlling valves 14, 24, 34 and 44, respectively. Then pressures P1-P4 necessary to give flow rates V1- V4 to the pipes 1-4 from pressure arithmetic devices 15, 25, 35 and 45 are supplied to a signal selector 5, and the highest level is selected by the selector 5 among P1-P4. This selected maximum level of pressure is supplied to a controller 6 of a mainpipe 9 to change the number of reveolutions of a blower 8. Then the pressure of the pipe 9 is controlled so that the value of a main pipe pressure gauge 7 shows the maximum level of the supplied pressure.

摘要： PURPOSE:To accurately calculate the speed of a material to be inspected, by operating the speed of the material to be inspected fed by a skew roll from the outer diameter of the material to be inspected and the skew angle and the number of rotations of said skew roll and correcting the operated speed on the basis of the detection values of two sets of photoelectric sensors. CONSTITUTION:A material 1 to be inspected being a round rod fed while rotated at a constant pitch by the rotation of a skew roll 5 (5a-5h) having a skew angle preset thereto is subjected to flaw detection over the entire region thereof by a flaw detection head 9. The rotation detector 16 connected to the rotary shaft of the skew roll 5 by a coupling forms a pulse signal corresponding to the number of rotations of the skew roll 5 and a counter 17 counts the pulse formed by the detector 16. An operator 12 operates the speed of the material 1 to be inspected from the outer diameter of the material 1 to be inspected and the skew angle/the number of rotations of the skew roll 5. Further, the speed operated from the outer diameter of the material 1 to be inspected and the skew angle the number of rotations is corrected on the basis of the speed calculated from the difference between times required when the material 1 to be inspected passes photoelectric sensors 10a, 10b, 10c, 10d arranged at definite distance intervals. By this method, the actual speed of the material to be inspected can be accurately calculated.
