Latest Patents

Kawasaki’s listed patents address the design and operation of corona-discharge chargers.

“Charger for Performing a Corona Discharge” describes a charger that applies voltage to a discharging electrode. Its electrode plate has multiple projecting portions, each containing groups of projections arranged adjacent to one another in the plate’s thickness direction.

“Corona Charger for Image Forming Apparatus Providing Uniform Surface” concerns charging a recording medium before light forms an electrostatic latent image on its surface. The design combines a projecting discharging electrode, a conductive shield case, an insulated holding member, and a conductive grid electrode. Its power supply sets the currents through the grid electrode and shield case to approximately equal values. One version moves the discharging electrode toward the recording medium to adjust those currents until they reach a predetermined reference value.
