摘要： PURPOSE:To improve the inspection sensitivity by using a vibrator array for an ultrasonic-wave transmitter and receiver, controlling the vibrator array and generating an apparent sound source point, and controlling the spreading mode of an ultrasonic wave according to an object of inspection. CONSTITUTION:The ultrasonic wave transmitter and receiver 2 is composed of an array (not shown in figure) of 2n vibrators and a spot sound source whose spread mode of an ultrasonic wave is controllable is scanned by using the transmitter and receiver 2 to obtain data for synthetic aperture. Namely, the transmitter and receiver 2 is shifted by a scanning mechanism 3 to respective positions A, B, C, and D in order and then the spread mode of the ultrasonic wave at the respective positions A-D is controlled. Consequently, the ultrasonic wave never propagates to, for example, a point P even if the ultrasonic wave is reflected at the point P, so no unnecessary echo is generated and noises in an image within an inspection objective range L are suppressed.

摘要： PURPOSE:To make a faithful detection possible with a high S/N by arranging divisionally an oscillation detecting coil and synthesizing respective detection signals from coils through corresponding delay circuits and transmitting them to a discriminator to select plate waves having a specific mode from propagated plate waves. CONSTITUTION:Signals similar to plate wave waveforms are induced in detecting coils 19a-19d and are supplied to delay circuits 20a-20d. Each signal is delayed by a time set by a delay controller 22 and has the same phase and is sent to an adding circuit 21. Signals Da-Dd are added in the adding circuit 21 to generate a wide-amplitude signal A having a spread similar to that of plate waves, and this signal A is sent to a discriminator 14 through an amplifier 13. The discriminator 14 discriminates the attenuation quantity and the propagation time of plate waves on a basis of this signal and discriminates finally properties of a sample plate body 16. Thus, the resolution is improved, and the oscillation is great, and therefore, the S/N is improved to make accurate discrimination possible.

摘要： PURPOSE:To detect the faults of a signal transmission circuit by measuring the currents in the single or plural positions of the signal transmission circuit of a flaw detector in the stage of transmission of an ultrasonic wave and diagnosing the waveforms thereof. CONSTITUTION:A resistor 2 and a capacitor 3 are connected in series to both terminals of a high voltage DC power source 1, and a switch 4 for signal transmission from a connection point P1, a damping resistor 5 and a signal transmission coil 6 are connected thereto. A current probe 8 between the outputs of the coil 6 and the power source 1 detects the current flowing in the coil 6. A current probe 9 between the output terminal on the negative side of the power source 1 and the earth detects the current flowing from the coil 6 through the earth to the power source 1. The outputs of the probes 8, 9 are transmitted via pass filters 10, 13 to zero cross detectors 11, 14. A decision circuit 15 decides the presence or absence of any fault in an electromagnetic ultrasonic wave transmission circuit from the signals of the detectors 11, 14 and feeds the output thereof to a control circuit 16.

摘要： PURPOSE:To reduce a minor lobe to improve a direrctional pattern, by winding an eddy current generating coil so that the windig density is high in the inside and is low in the outside. CONSTITUTION:When a DC is flowed to a magnetic field generating coil 2 wound around an iron core 1, a magnetic field B is generated near the surface of a material 4 to be examined. A gnerating coil 3a arranged on the lower face of the iron core 1 is wound spirally so that the winding density is high in the inside and is low in the outside. When a current (i) is flowed to the eddy current generating coil 3a, an inside density II of the eddy current is higher than an outside density Iphi, and an inside force FI of a force F generated on the surface of the material to be examined is larger than an outside force Fphi. It is known that a minor lobe is suppressed when the peripheral part is oscillated more weakly than the center in the field of the ultrasonic oscillator, and thus, the minor lobe becomes smaller than conventional lobes.

摘要： PURPOSE:To sense the presence or absence of a main in the space to be detected without fail by memorizing the reflected wave of an ultrasonic wave when the man is absent, and comparing the wave with that when the man is present. CONSTITUTION:If the man 11 is absent in a cage 2, the reflections of the output signals B of a receiving element 4 become the reflectd waves X1 and X2 from hand rails 12 and a floor. The signals B are detected by a binary coding circuit 6, become binary coded output E, and are given to a memory device 7 and a comparator 8. While the output E of the binary coding circuit 6 is directly given to the comparator 8, and compared with the quantized time signal F (the signal stored when the man is absent) from the memory device 7 in the comparator 8. If both signals are coincided, the comparator 8 does not give the calculating input to a calculator 9. Therefore, the presence of absence of the man in the cage 2 can be sensed without fail.

摘要： PURPOSE:To enable testing with high precision of a specimen with an extensive sampling period of digitalization, by irradiating a chirp supersonic wave onto a specimen surface and analyzing and processing an envelope of a signal detected from echo. CONSTITUTION:By a chirp signal emittor 510, the chirp signals are irradiated with the specified repetition period and ultrasonic wave is irradiated from a transducer 2 to a specimen 1. The ultrasonic wave reflected by rear surface B, notched part F of the specimen 1 is introduced into an A/D convertor 540, through transducer 2, amplifying circuit 5, envelope extractor 520. On the other hand, on output of the amplifying circuit 5 is introduced into a gate signal forming circuit 350 also and while defective echo or rear surface each is detected, the A/D converted outputs are stored consecutively in a memory 550. Further, by a micro-computer 560 echo of the specimen to be inspected is compared with the rear surface echo which is not provided with the defective part F preliminarily stored and if it is found different, judgement is given as defective and its position is defected by a signal frequency.

摘要： PURPOSE:To recognize the 3-dimensional form of a subject at a high speed and in simple constitution by detecting an echo arrived from the subject of a chirp ultrasonic wave, and amplifying and processing the echo. CONSTITUTION:When a chirp signal is produced, a chirp ultrasonic wave is radiated to a subject 4 and a table 3 from an ultrasonic wave transducer 2. Then the echos arrived from the subject 4 and the table 3 are detected by the transducer 2. These echos are amplified at the peak value by an AGC amplifier 51. The amplifier 51 detects the peak value between the start of the echo and the time T of the chirp signal. Then the gain of the amplifier 51 is increased if the detected peak value is smaller than a prescribed level and then reduced when the peak value exceeds the prescribed level respectively. Then the echo peak value is set at the prescribed level since the AGC action is repeated. Then the standardized echos are obtained and the wave is detected through a detector 6 to be supplied to a signal processing circuit 7.
