Title: Circuit for suppressing in-phase current of subscriber line
Inventor: KANEKO KAZUHIRO
IPC: H04M3/00
Filed: 1983-03-18
Abstract: PURPOSE:To suppress the subscriber line in-phase current even if a DC potential applied to a TIP and a RING line is different by detecting an AC potential to be superposed and both DC potentials of a subscriber line, cutting off the respective DC potential, adding the AC potential so as to feed back only the AC component to a feed circuit. CONSTITUTION:The polarity of the AC potential applied to the TIP line is amplified inversely by an amplifier OP4 of a detecting circuit DETT detecting the DC potential of the TIP line of the subscriber line and the AC potential superposed on it. This is similar to the RING line. The potentials are applied respectively to a capacitor C in an AC component selecting circuit CX. Thus, the DC component is cut off, only the AC component is inputted to the amplifier OP6, its output is fed back to operational amplifier circuits AT, AR, so as to reduce the impedance viewing the left side feed circuit from a point alpha of the TIP line and from a beta point on the RING line. Thus, the in-phase current applied externally is suppressed.

Title: Control method of toner density
Inventor: YUGE SHIZUO
IPC: G03G15/08
Filed: 1983-03-17
Abstract: PURPOSE:To maintain constant developer density by sticking toner to members which are held at specific potentials respectively, and detecting the amounts of stuck toner and supplementing toner so that a constant mixing ratio is kept. CONSTITUTION:A toner density detection roller 35 is connected to a positive. negative bias power source, and photodetecting elements provided to rollers 35a and 35b detect the amounts of stuck toner Ta which is electrified positively and stuck toner Tb which is electrified negatively. When the mixing ratio of both positive and negative electrostatic charge toner particles varies as the developer is consumed, the amounts of sticking to ther rollers 35a and 35b vary, so a toner supplement roller 32a or 32b is rotated by a driving motor according to a signal from a photodetecting element to supplement necessary toner Ta or Tb. Thus, variation in the mixing ratio of the toner is detected and toner is supplemented so that the mixing ratio is held constant, thus maintaining constant developer density.
