Title: Toshitaka Ogawa: Innovator in Inkjet Technology
Introduction
Toshitaka Ogawa, an accomplished inventor based in Ibaraki, Japan, has made significant contributions to the field of inkjet technology. With a remarkable portfolio of 19 patents, his innovations have greatly impacted the efficiency and functionality of inkjet printing devices.
Latest Patents
Ogawa's most recent patents include a line scan type ink jet recording device and an improved inkjet head configuration. The line scan type inkjet recording device features a recording head equipped with multiple nozzle orifices arranged in a row, which confronts a recording medium as it moves. By charging ink droplets ejected from the nozzle orifices according to their deflection amounts, Ogawa's design allows multiple ink droplets to impinge on the same pixel position or a nearby location. This innovative approach enables the backup of broken nozzles, ultimately reducing recording distortion.
His patent regarding the inkjet head involves a design that incorporates a nozzle, pressure chamber, multiple restrictors, and a common ink chamber. This arrangement increases fluid resistance within the restrictors without lowering the Helmholtz resonant frequency, allowing the inkjet head to operate at high frequencies while minimizing any adverse effects from residual pressure waves on subsequent ink ejections.
