    • PURPOSE:To evaluate fluctuations of diameter of thin wires accurately and at high precision, by displaying and recording the wire diameter measured by radiating laser beam in analog form. CONSTITUTION:In a laser beam diameter measuring apparatus 1, when a laser beam from a laser oscillator 4 is radiated to a thin wire 6, a Fraunhofer diffraction figure 8 is formed in the process of the laser beam passing through a lens group 7. This diffraction figure 8 of laser beam passes through a rotating single hole disc 9 rotated at a specified period and a slit 10 at a specified interval, and is sent to a photoelectric transducer 12. Since the photoelectric element 12 generates a photo signal every time a Fraunhofer diffraction figure is received, the signals are amplified and shaped in a shaping circuit 14, and counted in a counting circuit 15 which outputs a three-digit digital signal expressing the wire diameter. This signal is converted into an analog signal in a digital-analog converter 2, of which output is sent into an analog type display recorder 3.

    • PURPOSE:To make it possible to hold contents of a RAM for a long time even if a main power source is broken, by mounting a small-size cell on a substrate and connecting an external large-capacity cell in parallel to the cell above. CONSTITUTION:Small-size and light-weight reversible cell 6 is mounted on substrate 4 together with RAM5, and large-capacity cell 2 is connected in parallel to cell 6. when switch 3 is made, the output of main power source 1 is supplied to cells 6 and 2 and RAM5 through switch 7, abd RAM5 is operated by the output of power source 1, and simultaneously, cells 6 and 2 are charged. When switch 3 is broken and the output of power source 1 is broken, switch 7 switches the power source to cells 6 and 2 immediately. Consequently, outputs of cells connected in parallel are supplied to RAM5, and contents of RAM5 are held. Since power is supplied from cell 2 besides cell 6, RAM5 can be backed up sufficiently even if switch 3 is opened for a long time.

    • PURPOSE:To enable combined inspection, by setting one of the current feed terminals of a variometer at the ground potential and bringing the ground potential part of an eddy current flaw detector into contact with a wire. CONSTITUTION:The measuring section of a variometer 2 comprises a pair of current feed terminals 7, 7' and a pair of voltage measuring terminals 8, 8'. One current feed terminal 7 at the side of a flaw detector 3 is connected as a grounded terminal to the earth U. The measuring section of the eddy current flaw detector 3 comprises a high-frequency coil 11 and a measuring coil 12. A roller-type grounded terminal 13, which comes into contact with 1, is provided on a part of the measuring section of the flaw detector 3, which is located at the side of the variometer 2. The grounded terminal 13 is connected to the earth U and a current feed circuit 4. The variometer and the eddy current flaw detector are thus provided with grounded potential parts respectively so that a change factor from each of the variometer and the flaw detector toward the other is conducted out. As a result, the homogeneity and surface state of the wire can be jointly inspected.
