IPC: G03G9/08
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To enhance the reproducibility of a copied image formed and recorded on a sheet-like transfer material with respect to given image information by impressing an AC electric field vibrated in a specified direction on developer attached to the outside circumferential surface of a latent image carrier. SOLUTION: Either AC bias B1 or B2 is impressed on the electrodes 6B and 6C of a bias device and an electric mutual action is generated between the electrodes 6B and 6C and a photoreceptor drum 3. Then, the AC electric field corresponding to the electric mutual action between the electrodes 6B and 6C is generated at the optional position of the outside circumferential surface of the drum 3 and the AC electric field E being the synthetic vector thereof is generated at that position. That means, the AC electric field E is provided with the component vector V1 being in parallel with the radial direction of the drum 3 and the component vector V2 being in parallel with the circumferential direction of the drum 3 at that position. Then, when the electric field E is impressed on the developer, the developer attached to that position is vibrated in a direction being in parallel with the radial direction of the drum 3 by the vector V1 and vibrated in a direction being in parallel with the circumferential direction of the drum 3 by the vector V2.

Title: Digital input circuit
Inventor: EGAMI NORITAKA
IPC: H03K17/22
Filed: 1982-10-09
Abstract: PURPOSE:To prevent securely the misreading of digital input data which occurs in the event of an instantaneous power failure by inputting an AC supply voltage to a comparator and latching input data by its output signal. CONSTITUTION:A voltage with a full-wave rectified waveform is outputted from an AC power source 15 through a transformer 18 and a diode bridge 19, and a timing pulse A is sent out as the output signal of the comparator 17 when the rectified waveform almost has a peak value. If an instantaneous power failure occurs in the power source 15 at a point B of time, the negative-side input terminal of the comparator 17 is at 0V and the voltage holding time of the positive input terminal is held longer than a specific time in a DC rectifying power source, so a positive voltage is applied throughout the instantaneous power failure. Consequently, the generation and transmission of an erroneous signal are prevented in the period of this instantaneous power failure.
