Title: Schmitt trigger circuit
Inventor: MATSUMOTO KAZUYA
IPC: H03K3/353
Filed: 1986-07-28
Abstract: PURPOSE:To set the threshold value of leading and trailing level with a high degree of freedom without increasing the gate capacitance of an input FET by returning an output voltage of the post-stage to a gate terminal of a 3rd and a 4th FETs so as to for, a 2nd feedback loop. CONSTITUTION:A threshold voltage Vt1 of an input signal when an output signal changes from a low to a high level is larger than a threshold voltage V/0 at the absence of feedback FETs 6, 9, 10, and a threshold voltage Vt2 when the output signal changes from a high to a low level is smaller than a threshold voltage Vt0 at the absence of the feedback FETs 6, 9,10. Then the threshold voltage Vt1 depends of,e.g., the gate width of the FET 6 and the voltage Vt2 depends on, e.g., the gate width of the feedback FETs 9,10. Thus, the voltages Vt1, Vt2 are set with high degree of freedom without fluctuating a load to the input signal source (without changing gate capacitance of input FETs 4, 5) and the difference between both the threshold values is increased sufficiently.

Abstract: PURPOSE:To cover a developing agent from the outside air so that the agent does not absorb moisture, by recovering the developing agent attracted to the whole surface of a developing roll to a developing agent container tank when no developing work is made. CONSTITUTION:Even when a developing agent 6 attracted to a photosensitive drum 1 in a developing area from an opening 5 to a stopper 4 is consumed by developing works, the developing agent 6 is successively supplied from the developing agent container tank 3 and the tuft height of the developing agent supplied from the tank 3 is maintained at a fixed one which is determined by the number of revolution of a nonmagnetic hollow sleeve 2a and the number of revolution and number of pole of a permanent magnet 2b. When the developing work is terminated, the rotation of the permanent magnet is stopped at first and then the sleeve 2a is stopped with a little time lag. Then whole developing agent 6 attracted to the surface of the sleeve 2a in the developing area from the opening 5 to the stopper 4 is recovered into the container tank 3. Therefore, whole developing agent 6 is contained in the container tank 3 when no developing work is made. In this way, stable development is made possible.

Abstract: PURPOSE:To eliminate the need for a fast speed processing for the operating component and to make the device immune to surrounding noise by providing an A/D converter exclusively at a high input level and a low input level respectively and using the converters switchingly depending on the output state. CONSTITUTION:An amplifier 1 amplifies an analog input and the A/D converters(ADC) 2, 3 whose characteristic is nearly arranged convert an analog signal into a digital signal. An adjusting device 4 obtains a ratio of signal levels of digital signals inputted from A, B and after A, B inputs are arranged, when the ADC 2 overflows, the input from the ADC 3 is outputted and in other case, the input from the ADC 2 is outputted. Thus, even when the analog signal level is smaller, since an analog signal with a large amplitude is always subject to A/D conversion, the device is immune to the surrounding noise and the A/D converter with high resolution is realized by using the A/D converter with low resolution and the operating speed is the speed for a conventional device.
