Title: Image forming device
Inventor: KIYONO YUZO
IPC: G02B26/10
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device whose quality is high by controlling laser output fluctuation by setting the respective operation currents of plural light emitting sources based on first and second light quantity control signals by a laser driving means. SOLUTION: The laser driving means sets the respective operation currents of the plural light emitting sources based on the first and second light quantity control signals. The correction of laser light output caused by the temperature fluctuation of a device and the dispersion of laser light is performed by the first light quantity control signal which is the output of D/A converters 401-404. The laser light output correction due to the fluctuation of cavity temperature caused by self-heat generation and heat interference made by a laser modulation signal is performed by the second light quantity control signal generated by updown counters 601-604, the D/A converters and a low pass filter(LPF).  Thus, a laser driving current is superposed based on the first and second light quantity control signals, so that laser light output adjustment is always performed while image-forming and an uniform laser light output is obtained.

Abstract: PURPOSE:To detect accurately the travelling azimuth of a travelling object regardless of the position of a magnetic azimuth sensor, by compensating the offset and sensitibity to the azimuth sensor and at the same time securing the free rotation of the sensor. CONSTITUTION:An energizing circuit 9 transmits the AC signal to a ring core 2 of a sensor head part 8 to give the periodical saturation and unsaturation to the core 2.

Then the bias voltages supplied from the X and Y component offset control parts 13 and 14 are added together at the X and Y component sensitivity control parts 15 and 16. Thus the sensitivity is controlled. The X and Y component outputs are applied to the output terminals 17 and 18. The X and Y recorders are connected to the terminals 17 and 18, and a car is rotated 360 deg.. Then the parts 13 and 14 are controlled based on the oval locus of the output to obtain a circular locus. Thus the travelling azimuth is accurately detected.
