Title: Innovator Spotlight: Kunihiro Yamauchi and His Contributions to Ink Jet Technology

Introduction: Kunihiro Yamauchi, an accomplished inventor from Hino, Japan, has made significant contributions to the field of ink jet technology. With two patents to his name, he has demonstrated ingenuity in creating devices that enhance the precision and efficiency of ink jet printing. His work at Konica Corporation has positioned him as a key player in the industry, allowing for advancements in printing technology.

Latest Patents: Yamauchi's latest innovations include two patents that revolutionize the design of ink jet heads. The first patent describes an ink jet head comprising partition walls made of piezoelectric material, which divide ink chambers. This design features driving electrodes on the partition walls and leads conductors at the bottom of each ink chamber connected to a driving circuit. The voltage applied through the lead conductors causes the partition walls to deform with shearing forces, resulting in a precise jet of ink from each chamber.

His second patent outlines a method for manufacturing the ink jet head. This process entails jetting ink from a nozzle hole by applying an electric voltage to an electrode that deforms the ink chambers divided by a partition wall. The design involves placing multiple piezoelectric base plates with polarization side by side on a non-piezoelectric plate, creating grooves for ink chambers, and subsequently mounting a second non-piezoelectric plate to form the final product.
