摘要： PURPOSE:To to perform accurate measurement and, at the same time, to minimize the power consumption of the module by intermittently driving a signal processing circuit. CONSTITUTION:In an intermittent drive control circuit 23, the (+) and (-) output terminals of a DC power source are connected to the (+) and (-) input terminals of a signal processing circuit 22 through wires 23a and 23b and a timer relay 25 is connected between the wires 23a and 23b. When a voltage is applied across the circuit 23 from an external power source connected to a power supply terminal 13, the relay 25 in the circuit 23 performs opening and closing operations on a contact 25a in a certain cycle. The power supply to the circuit 22 is intermittently performed following the cycle set by means of the circuit 23. Therefore, the circuit 22 drives a composite thin film sensor 21, processes the information detected by the sensor 21, and outputs the processed results through a terminal 14 only when the power supply is made to the circuit 22. Since the sensor 21 is intermittently operated in such a way, the temperature rise of the whole sensor 21 becomes smaller even when the sensor 21 generates heat at the measuring time. Therefore, mutual interference between thin film sensors can be prevented and accurate measurement can be performed. In addition, since the sensor is intermittently operated, the power consumption of this module can be minimized.

摘要： PURPOSE: To realize an abnormality detector which can detect the amount of abrasion or breakage of pantograph, deformation of the frame, etc., automatically for a train running at low speed. CONSTITUTION: The abnormality detector for pantograph comprises optical sensors 4a, 4b for detecting entrance of a train 7 when a laser light is intercepted, an illuminator 3 for irradiating the pantograph 5 of the train 7 with light from the side face thereof, a plurality of slits 1a, 1b, 1c for projecting a slit laser light toward the pantograph 5, a plurality of video cameras 2a, 2b, 2c for picking up the image of the pantograph 5, an image processor 29 receiving images from the cameras 2a, 2b, 2c, a record display 28 and a controller 30 connected with the image processor 29. This constitution realizes automatic instantaneous detection of the amount of abrasion and breakage of the pantograph 5 and deformation of the frame 15. Since the detector has simple structure including no movable section, the reliability is enhanced and since the data is collected at high rate, measurement can be made even during low speed running of the train 7 and a safety detector can be realized through remote operation.

摘要： PURPOSE:To enhance a flaw detection property in a specific direction by a method wherein the direction of an eddy current is made variable by an external control operation. CONSTITUTION:Individual coils 11, 12 are wound in such a way that they are set at right angles at definite intervals, i.e., in parts indicated by dotted-line circles 15 at the rear surface of a support body 14. In a flaw detection operation, a driving current is supplied separately to the coils 11, 12, and they are brought close to an object 20 under test. When an eddy-current sensor 10 is brought close to the object 20 under test, an eddy current is generated on the object 20 under test according to the driving current of the coils 11, 12. The eddy current changes its direction according to the phase of a high-frequency current flowing in the individual coils 11, 12, and the direction of a composed eddy current is changed by it. Consequently, when the phase of the eddy current supplied to the individual coils 11, 12 is made variable, the direction of the composed eddy current generated on the object 20 under test can be set arbitrarily, and the inspection property of a flaw in a specific direction generated on the object 20 under test can be enhanced.

摘要： PURPOSE:To measure the appearing time of each signal waveform and the peak value simultaneously without requiring previous examination of the appearing time. CONSTITUTION:The waveform of an ultrasonic flaw detection signal outputted from a flaw detector 1 is binarized at a reference level by means of a comparator 25. A time counter 5 measures the time when the first waveform appears in a set of signal waveforms when a signal waveform higher than the reference level appears within a predetermined time after appearance of another signal waveform higher than the reference level and the time thus counted is latched in latch circuits 21a, 21b,... On the other hand, peak hold circuits 36a, 36b, measure the highest peak value in a series of signal waveforms before binarization and hold the highest peak value. Two types of measurement are effected continuously. The measured times latched in the latch circuits 21a, 21b,... and the values held in the peak hold circuits 36a, 36b,... are then selected sequentially and delivered to an external machine.
