摘要： PURPOSE:To obtain the title ultrasonic flaw detector which is operated by a remote controller and performs both normal flaw detection and accurate flaw detection by itself by varying the quantity of engagement between gears for transmitting the power of each driving part properly according to circumstances. CONSTITUTION:An operator of the detector judges which of the normal flaw detection and accurate flaw detection is performed at a stage of judgement 50 and operates the controller panel 51 of the ultrasonic flaw detecting device 5. When the normal flaw detection mode 52 is specified, the distance between respective driving part gear shafts of the ultrasonic flaw detector 5 increases, but the quantity of engagement between the gears decreases, thereby performing the fast flaw detection with low accuracy. When the accurate flaw detection mode 53 is specified, on the other hand, the distance between the gear shafts of the respective driving parts of the ultrasonic flaw detector 5 decreases and the quantity of engagement between the gears increases, thereby performing the slow flaw detection with high accuracy.

摘要： PURPOSE:To saturate a body to be inspected magnetically, to achieve the miniaturization and wt. reduction of a detection part, to prevent the lowering of a noise level and to enhance reliability, by using a superconductive magnetizing coil in a DC magnetizing coil part. CONSTITUTION:A flaw detection apparatus is constituted of a superconductive magnetizing coil 1 composed, for example. of yttrium showing superconductivity at high temp., a cooling material 2 such as liquid nitrogen cooling the coil 1, a cooling material holding container 3 constituted of a heat insulating material, a cooling material supply apparatus 4, a power source 5, detection coils 6, 7, an oscillator 9, a bridge circuit 10, an amplifier 11, a phase shifter 12, a detector 13, a display device 14 and a recorder 15. The superconductive magnetizing coil 1 can form current density higher than that of a usual magnetizing coil and high flux density which can not achieved by the usual magnetizing coil can be obtained. By this constitution, since a body 8 to be inspected can be magnetically saturated by supplying a high magnetic field, noise due to difference in a magnetic characteristic is reduced and a S/N ratio can be improved.

摘要： PURPOSE:To automate the recording of data and to attain miniaturization and wt. reduction, by constituting the titled apparatus so that a signal showing the finish of take-in at the same time when a probe position signal and the peak value and path length of an echo signal are taken-in. CONSTITUTION:The output signal of an ultrasonic flaw detector 2 is divided into a peak value P and a path length T to be sent out to a microcomputer 3 through an ultrasonic signal take-in circuit 4. A probe position take-in circuit 5 sends out output voltages of potentiometers 204, 205, 206 for generating position signals of X, R, theta to the microcomputer 3 and a data take-in order display part 6 sends out an interruption signal for taking in data to the microcomputer 3. The gain value of a gain input circuit 7 is set by an inspector and a function key 8 performs the selection and display of various flaw detection method. A memory part 11 stores the taken-in data in a cassette 219. The data stored in the cassette 219 are inputted to a general-purpose computer for processing data by off-line processing and analyzed, processed and arranged to be outputted as various charts such as a plan, a cross section, an evaluation list or the like and the evaluation of a flaw is made easy.
