Title: Innovations of Zen Kurokawa in Inkjet Technology
Introduction
Zen Kurokawa is an accomplished inventor based in Corvallis, OR (US). He has made significant contributions to the field of inkjet technology, particularly through his innovative designs that enhance printer performance. His work is characterized by a focus on improving print density and operating frequency.
Latest Patents
Kurokawa holds a patent for a "Special geometry ink jet resistor for high dpi/high frequency structures." This invention involves an inkjet printhead structure that features novel resistor circuitry fabricated on two different substrate layers. The dual-layer circuitry minimizes the required substrate surface area and printhead shelf length, thereby increasing the printer's operating frequency and print density. In one embodiment, heating resistors are strategically spread across the substrate surface area, with conductors attached to opposite ends of the heater resistors in a unique configuration. This design simplifies routing by coupling multiple heater resistors to the same conductor return path located on a second conductive layer. Additionally, the heater resistors are shaped like trapezoids to ensure uniform heating, with alternative resistor shapes introduced to maintain consistent heat dissipation despite variances in resistor/conductor sheet resistance.
