Hitoshi Kida, Ibaraki JP
| Patent application number | Description | Published |
|---|---|---|
| 20080316280 | Liquid discharging head, method of manufacturing liquid discharging head, and image forming apparatus - A liquid discharging head includes: a plurality of nozzles that discharge liquid droplets; and a plurality of piezoelectric elements that generate pressure for discharging liquid droplets from the respective nozzles, wherein the piezoelectric elements are performed with repolarization process to set non-uniformity of the droplet discharging characteristics of the nozzles to be in a predetermined range by combining adjustment of a polarization sensitivity and adjustment of a polarization voltage for each of the piezoelectric elements. | 12-25-2008 |
| 20090244202 | INK JET HEAD MANUFACTURING DEVICE, INK JET HEAD MANUFACTURING METHOD, AND INK JET DEVICE - In an ink jet head manufacturing device, first and second diodes are arranged on a path extending from a gate of a control unit to an individual electrode of an ink-pressure control part in an ink jet head, the first diode allowing a current from the individual electrode of the ink-pressure control part to flow into a first wiring, and the second diode allowing a current from a second wiring to flow into the individual electrode of the ink-pressure control part. A short-circuit unit is arranged to short-circuit the first wiring and the second wiring when depolarization or polarization of the ink-pressure control part is performed. | 10-01-2009 |
