Title: Magnetic flaw detection device for thin steel band
Inventor: IWANAGA KENICHI
IPC: G01N27/83
Filed: 1990-07-30
Abstract: PURPOSE:To enable sensitivity in width direction to be uniformly distributed and defect detection rate to be improved by measuring leakage flux from a magnetized thin steel band with a group of magnetic detection elements which are arranged in one row in width direction and then adding and integrating this detection signal. CONSTITUTION:Magnetic detection elements 1a-1n are arranged in one row in width direction of a thin steel band 3 at a specified gap at a center of a magnetic pole of a magnetized core 6. Then, when an outer peripheral surface of a hollow roll 2 is pressed to one surface of the steel band 3 with a specified pressure, the roll 2 is rotated in clock direction in reference to a rotary axis 4. In this state, when excitation current is supplied to an excitation coil 7, a magnetic path which is closed by the core 6 and the steel band 3 which is running so that flux within the steel band 3 is disturbed if there are defects within the steel band 3 or on the surface, leakage flux is generated, and it is detected by the elements 1a-1n. Then, amplitude and waveform of a signal corresponding to the amount of flux are converted, noise components are eliminated, and each signal of the mutually adjacent elements 1a-1n is added and integrated and is subjected to discrimination processing with sensitivity distribution being uniform in width direction of the steel band 3, thus enabling defect detection to be highly accurate.

Filed: 1986-08-26
Abstract: PURPOSE:To exactly reduce an error to >=1/4 by taking an absolute value from a detected waveform having two peaks, and also, detecting two peaks, and setting its center as a detected position. CONSTITUTION:By a pulse 2-1 which is sent to a vibrator pen 1-1, a piezoelectric vibrator in the vibrator pen 1-1 executes an electro-mechanical conversion, and an elastic wave is generated in a glass plate 1-3. In such a state, a waveform 4-1, namely, two pulse trains are set at suitable time Ts intervals, and the vibrator pen 1-1 is driven by a combined driving waveform so that an envelope 4-2 is obtained on the glass plate 1-3. Subsequently, by obtaining an absolute value of a detected waveform, and moving moderately the Ts in the driving waveform 4-1, phases in two peaks are set to a phase relation which is shifted by pi/2. Thereafter, peaks P1, P2 are detected, and the center of these two peaks is detected as a position (coordinate or distance). In such a way, a detected error which is one period portion goes to a 1/4 period portion, an error range is reduced exactly to 1/4, and the accuracy is raised.

Abstract: PROBLEM TO BE SOLVED: To accurately decide the possibility of a collision by extracting an object except an area whose horizontal length is equal to or greater than a prescribed length when an area rate is smaller than a prescribed rate. SOLUTION: A counter (j) is initialized to '1' (S31), and next, the area rate RATE of an object corresponding to the value of the counter (j) is calculated (S32). Whether or not the calculated area rate RATE is smaller than a prescribed rate RATETH is discriminated (S33), and in the case of the RATE < the RATETH, data whose horizontal length is equal to or greater than a prescribed length mTH is eliminated from the object (S34). Then, the counter (j) is increased (S35) and whether the value of the counter (j) surpasses the number (n) of objects is discriminated (S36). As a result, in the case of (j)>(n), the prescribed length mTH is made 1/2 (S37), an object label is updated (S38), and a divided object is extracted.

Then a travel course arithmetic part 11 finds the real azimuth at the initial position from the mean value and the quantity of azimuth variation from the initial position O to the straight travel which is stored in an azimuth variation detection part 8 and set this as the initial azimuth again. Then the travel course (solid line) from the initial position O to the current position is corrected according to this initial azimuth to find the real current position A.
