Title: Image recording device
Inventor: NISHIOKA NOBUAKI
IPC: G03G15/16
Filed: 1986-02-04
Abstract: PURPOSE:To reduce the cost of a high voltage unit by providing a means which monitors the operation state of a high voltage system charging a photosensitive body electrostatically with the output of a density detector for detecting the density of a specific image pattern. CONSTITUTION:Image recording (latent image) is finished and a CPU20 controls the projection of light 9 by itself at timing of distance B in a subscanning direction to write an AIDC mark (latent image) on a photosensitive body 1, thereby detecting the image density of the AIDC mark IP which is still visualized on the photosensitive body 1. If the density detection signal deviates from set condition, a signal indicating that the density is improper is inputted to the input port INI of the CPU20. The CPU20 sends a control signal to a toner supply motor incorporated in for example, a developing device 3 so as to optimize the image density. Thus, the density is adjusted automatically to density set with a switch 15. The output of a photosensor 13 is utilized to monitor the operation states of an electrostatic charging unit 2 and its high voltage unit 8 principally.

Title: Amplitude limiting circuit
Inventor: SHIMIZU FUMIHIKO
IPC: H03G11/02
Filed: 1987-02-03
Abstract: PURPOSE:To prevent amplitude variation from occurring even owing to power source variation and element variance by interposing a diode for series feedback between the emitter of a common emitter amplifier and the ground. CONSTITUTION:A series feedback resistance RF and the series feedback diode DF are interposed in series and in this order between the emitter of the TR Q1 and the ground. The dynamic impedance of the series feedback diode DF increases as the emitter current IE of the TR Q1, so negative feedback effect further increases as compared with that when the series feedback diode dF is absent, and the amplitude is suppressed in the active area side of a collector voltage Vc, i.e. output signal. For the purpose, the rate of a negative feedback quantity is varied dynamically according to how large the input signal is to suppress variation in the asymmetry of an output waveform, thereby suppressing variation in signal mean value. Consequently, phase variation can be suppressed.
