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 detect the occurrence of fault with good accuracy by performing the comparison operation of the operated value of the detection signal from a detecting part and set value plural times. CONSTITUTION:The vibrations generated in a bearing part are detected and amplified in a sensor amplifying part 1 and are applied to an effective value operating part 10 and peak value operating part 11 by way of a low-pass filter 8 and A/D converter 9. The outputs of the operating parts 10, 11 are compared in a comparing part 12. A decision part 6 receives the signal from the comparing part 12 and integrates with respect to the plural times of comparison operations, by which whether there is any fault or not in the bearing is decided. The results of the decision are displayed in a display part 7 and an alarm or the like is driven by an output part 13.

摘要： PURPOSE:To make it possible to monitor the malfunction of a bearing at all times by detecting the operating vibrations of the bearing and the discharging condition of lubricating oil. CONSTITUTION:Control valves 4 and 5 are connected with preset positions of the lubricating oil charging and discharging pipes 2 and 3 which have communications with the upper and lower sides of a bearing 1 or a test piece assembled in a machine such as a rotor. a foreign substance detector 7 is connected with the discharging pipe 3, and a vibration gauge 6 is attached to the bearing outer race 1a and connected with an arithmetic control unit 8. Thus, when any abnormal phenomena take place in the bearing 1, the vibratory output waveforms including the shock waveforms varying periodically or non-periodically are detected by the vibration gauge 6. When the waveforms become larger than the discrimination level, the control valves 4 and 5 are opened to effect the charge of the oil in a preset quantity. When the oil is discharged, a foreign substance is, if any in the oil, detected by the detector 7. Then, the valves 4 and 5 are opened so that the foreign substance is discharged from the bearing 1 together with the lubricating oil.

摘要： PURPOSE:To enhance the checking efficiency by securing the decision for the disconnection state of the pattern electrode plate by the light emitting state of the field effect material such as the liquid crystal. CONSTITUTION:Checked pattern electrode plate 1 provided on metal electrode 12, and a constant field is applied between electrode 12 and back electrode 9 via power source 13. Thus, liquid crystal 8 of the field effect type lights up as long as no disconnection takes place between the segments of plate 1. If the disconnection takes place there, no voltage is applied crystal 8 located between segment J and electrode 9 with no lighting there. Thus, the disconnection can be detected by lighting or no lighting, enhancing the checking efficiency.
