    摘要: An ultrasonic testing method uses surface waves to prevent false detection of primary cracks, to lower the level of structural noises from grain boundaries, and to improve the detectability in the ultrasonic testing by surface wave testing of hot rolling rolls. A surface wave probe 10 capable of transmitting and receiving a surface wave is provided with a piezoelectric element 10A, a resin wedge 10C disposed on the front surface of the piezoelectric element 10A and a damping block 10B disposed on the back surface. The surface wave probe 10 is driven to produce a short pulse having a pulse length being at most 2.5 times the wavelength of the surface wave to be produced. A coupling liquid medium is supplied to the probe 10 in accordance with the peripheral speed of the roll to be tested. Depending on the height of the reflected waves measured, the grinding allowance of the roll is determined, and the roll is ground according to the thus-determined grinding allowance. The roll may be tested while being partly ground, and the optimum grinding allowance of the roll may be determined.

    摘要: A tonearm control device in which tonearm position is detected by counting output pulses generated in response to a reversible electric motor output used for providing horizontal tonearm movement. A sensor is employed to detect non-recorded portions between recorded bands of music and also the initial position of a record disk. The sensor is supported on a supporting arm separate from the tonearm. The output pulses are counted in a counter of a RAM and the number of pulses corresponding to a distance between the sensor and the stylus of the cartridge is added in an adder in a CPU to the content of the counter. The output of the CPU is memorized in assigned positions of a memory in the RAM, the number of which corresponds to numbers of selected music. The contents of the memory are compared with the output pulses. When coincidence occurs, reproduction of the band of music is achieved. Hence, it is possible to change the cartridge independent of the sensor.
