Filed: 1982-06-18
Abstract: PURPOSE:To stabilize easily the oscillating frequency for an oscillator which is triggered with an input pulse of a stable frequency and delivers only a specific frequency, by performing control to fix the duty ratio of an output pulse. CONSTITUTION:An oscillator 31 is constituted with transistors TRQ1-Q4 and a capacitor C1 in the form of an emitter coupled multivibrator. Then a trigger TRQ5 is provided between both ends of the capacitor C1, and a signal -C having 1:40 duty ratio is supplied to the base of a TRQ21. The TRQ22 and Q23 as well as TRQ24 and Q25 which constitute current mirror circuits functioning as positive and negative current sources are set to the collector and emitter of the TRQ21. Then the emitter area ratio is set at 1:8 between the TRQ22 and Q23; while the emitter area ratio is set at 5:1 between the TRQ24 and Q25. As a result, the current ratio is set at 1:40 between the TRQ22 and Q24. The collector current of the TRQ21 is charged and discharged by a capacitor C2, and the emitter currents of the TRQ1 and Q2 are controlled to obtain a fixed potential of the collector current of the TRQ21.

Filed: 1983-06-14
Abstract: PURPOSE:To obtain a maintenance-free developing device by constituting the electrostatic charging sequence of material of the insulating layer of a metallic roll for removing different color toner entering the 2nd developing device selectively among materials positioned in a predetermined array.
