摘要： A tablet type coordinate input apparatus comprises a flat medium for propagating a longitudinal elastic wave, longitudinal elastic wave detecting elements disposed on part of the end-adjacent side surfaces or of the front surface of the flat medium, a longitudinal elastic wave input member having an end portion terminating in a sharp-pointed end and brought into pressure engagement at that end with any desired position on the surface of the flat medium to radiate the longitudinal elastic wave from that end, an amplifier circuit amplifying electrical signals indicative of the elastic wave detected by the detecting elements, a comparator circuit comparing the signals amplified by the amplifier circuit with a predetermined threshold voltage thereby generating delay pulse signals corresponding to the propagation times of the longitudinal elastic wave, a counter circuit counting the lengths of time elapsed from the time of radiation of the longitudinal elastic wave toward the flat medium as a result of pressure engagement of the input member therewith to the time of generation of the delay pulse signals, and a computing circuit computing the coordinates on the basis of the time signals applied from the counter circuit.

摘要： First and second magnetic poles are provided, which have end surfaces brought close and in opposition to a material to be examined. These magnetic poles are magnetized by a DC exciter coil such that the magnetic poles have opposite polarities. The first magnetic pole is provided at its end surface with a pair of cumulatively connected transmitting coils, and the second magnetic pole is provided at its end surface with a pair of differentially connected receiving coils. The transmitting coils are connected to a pulser which generates a pulse current, and the receiving coils are connected to a differential amplifier. An electromagnetic ultrasonic wave generated by the transmitting coils are received by the receiving coils, amplified by the differential amplifier, and thereafter supplied to a synchroscope and an automatic detector.

摘要： A supersonic or ultrasonic wave flaw detector in which acoustic boundaries of flaws and/or abnormality of materials within an object to be inspected is detected by supersonic or ultrasonic waves and the position and shape of such a flaw and/or abnormality are displayed. A hard object to be inspected is sector-scanned with a supersonic wave beam with a variable-angle beam probe in direct contact with the object. In a range of comparatively small incident angles at which the longitudinal wave mainly penetrates the object, sectional images due to echo signals of the longitudinal wave are displayed on a display screen with scanning lines representative of the transmission speed and direction of the longitudinal wave. In the range of large incident angles where the shear wave penetrates the object, on the other hand, sectional images due to the echo signals of the shear wave are displayed on the display screen with scanning lines representative of the transmission speed and direction of the shear wave. For this, the sweeping speed and direction for the display scanning lines are switched in accordance with the ranges of incident angles. The switched flaw detecting operation modes of longitudinal and shear waves thus combined covers a complete sectional image to be displayed on the display screen.
