Patent JP-H08274712-A (JP)
Title: Optical transmitter
Inventor: KOBAYASHI NORIFUMI
IPC: H04N7/16
Filed: 1995-04-03
Abstract: PURPOSE: To obtain an optical transmitter of simple constitution which can reduce the relative intensity noise of light signals by putting light signals outputted by plural light sources together and imposing intensity modulation with a sent signal. CONSTITUTION: This light signals outputted by the light sources 10a-10n which outputs the light signals having different wavelengths is composited into on light signal by a photos compositing unit 11. Then an external modulator 12 imposes intensity modulation on the composite light signal with its sent signal. Because of this constitution, noise electric power after the composite light signal is received is the result of voltage addition of noises because noises of the respective light signals inputted to the optical modulator 11 have no correlation; and a mean electric power is the addition of DC lights and the result of voltage addition. Consequently, the S/N of the light signal can be made large by reducing the relative intensity noise of the composite light signal. The external modulator 12 inputs the sent signal through a driving circuit 13 and preferably impose intensity modulation on the composite signal with the sent signal.

Title: Subscanning method
Inventor: YOSHIZAWA TAMOTSU
IPC: G03G15/22
Filed: 1981-05-22
Abstract: PURPOSE:To obtain an image of high quality, by supplying the driving pulse of the frequency prescribed for each step to a microstep driving circuit in accordance with the error of the stepping angle of a stepping motor. CONSTITUTION:An ROM2 stores a program to deliver the compensated driving pulse, and a memory 3 stores each stepping angle of a stepping motor 5. When a power supply is applied, an agreement is obtained between the contents of the memory 3 and the energized phase of the motor 5 by the power-on reset signal 6 which is supplied from a power-on resetting circuit. Thus a microstep driving circuit 4 and a CPU1 are initialized. When the recording starts by the start signal, the CPU1 reads a compensated data out of the memory 3 and accordingly delivers the driving pulse to the circuit 4. As a result, the flextion of a scanning line and the variance of the pitch which are caused by a stepping error can be compensated. Thus a scanning line which is substantially linear with no pitch variance can be recorded.
