摘要： PURPOSE:To efficiently measure the hardness of a magnetic material member without exerting external force at all to the magnetic material member or destructing said member by obtaining the current value at which the residual magnetism of the magnetic material member changing in conformity with the hardness of the magnetic material member to be measured is made zero. CONSTITUTION:A primary coil 10A for generating a magnetic field and a secondary coil 10B for detecting a magnetic flux are wound as a yoke 8 of a magnetic sensor as a magnetic path forming part having a U-shaped section. The magnetic material member 2 to be measured is pressed to such sensor 4 to form a closed magnetic circuit. A coil sensor driving means 6 is connected to the sensor 4. Electric current for excitation is passed from a primary circuit 6A of the means 6 to the coil 10A to magnetize the member 2 to the satd. region. The demagnetization current in the reverse direction is then passed from a secondary circuit 6B to the coil 10A so that the residual magnetism of the member 2 is made zero. The current value at which the residual magnetism changing in conformity with the hardness of the member 2 is made zero is displayed on an ammeter 24 as a means for displaying the current value. The hardness of the member 2 is thus efficiently measured.

摘要： PURPOSE:To perform the bonding of plastic work relatively in a short time as well as obtain a sufficient bonding strength, by providing an automatic value divergence regulating means which regulates adequately the valve divergence of a variable pressure-regulating valve according to the output of a work deformation detecting sensor. CONSTITUTION:A pressure value and a pressing time are entered and set in advance in an automatic valve divergence regulating means 7 by an operator. Besides, the deformation data of a work 1 is to be entered from a work deformation detecting sensor 6 into the automatic valve divergence regulating means 7. The automatic valve divergence regulating means 7 into which each information has been entered processes a computation with a microcomputer and outputs a drive control signal to operate a variable pressure-regulating valve 5 so as to output a required specified pressure from an air cylinder 3. As a result, the air cylinder 3 acts according to an applied air pressure, and the specified static pressure to be applied is varied for the work 1 according to the progress of ultrasonic welding.
