Title: Phase compensating method for insulation resistance measuring instrument
Inventor: MATSUNO TATSUJI
IPC: G01R27/18
Filed: 1987-01-16
Abstract: PURPOSE:To correct the phase shift of a low-frequency signal for measurement at low cost all the times by adjusting the phase of the low-frequency signal for measurement which is applied to a synchronous detector provided on the secondary side of a current transformer coupled with an earth line, and approximating the output of the synchronous detector to zero. CONSTITUTION:The output terminal of a power amplifier PAMP is connected to the secondary side of a transformer OT through a changeover switch SW1 and a phase control circuit PC which generates the low-frequency signal for measurement is connected to the input side of the PAMP. When the switch SW1 is connected to a broken-line side, the primary side of the transformer OT is terminated by a resistance R1, so a current which flows through a conductor penetrating the current transformer ZCT through a capacitor C shifts in phase by 90 deg. through the PAMP. At this time, the value or polarity of the output D1 of the synchronous detector MULT is discriminated and the phase of the low-frequency signal for measurement applied to the MULT through a filter FIL is adjusted to approximate the output D1 to zero, thereby eliminating the phase shift of a measuring circuit.

Title: Optical picture drawing device
Inventor: FUKUSHIMA MIKI
IPC: H04N1/23
Filed: 1988-01-18
Abstract: PURPOSE:To form an optical system being free from a picture drawing distortion by using an inexpensive single lens by providing a frequency modulator and modulating a fundamental clock for taking a timing of switching of a light beam at the time of drawing a picture. CONSTITUTION:When a data processing part 11 reads in picture data to be brought to picture drawing from a recording medium of the outside, the data processing part 11 sends successively the data which is read in, to a converter 12. The converter 12 converts the sent data to raster data and outputs it to an optical modulator 15, and the optical modulator 15 takes a timing of ON and OFF by using a frequency which has been modulated by a frequency modulator 14 as a fundamental clock. The frequency modulator 14 synchronizes a rotation of a rotary polygon mirror 17 and the frequency modulation by receiving a signal from a photodetector 19. In such a way, since the fundamental clock is fluctuated in the same ratio as a fluctuation of a scanning speed, a picture drawing distortion can be corrected, and an optical system being free from the picture drawing distortion can be obtained at a low cost.

Then, scales on the surface of the hoop are perfectly removed by pickling. In this case, by making the molten salt bath above-mentioned composition, the quantity taken out adhering to the steel hoop is decreased remarkably and the cost can be reduced by decrease of consumption of the molten salt bath.
