Title: **Inventor Motonobu Hoshino: Trailblazer in Ink Jet Technology**

Introduction

Motonobu Hoshino, an esteemed inventor based in Saitama, Japan, has made significant contributions to the field of ink jet technology. His innovative designs have led to the development of advanced ink jet heads that leverage piezoelectric materials for precise ink dispensing. With a total of two patents to his name, Hoshino continues to push the boundaries of what is possible in printing technology.

Latest Patents

Hoshino's latest patents focus on two groundbreaking inventions. The first is an **ink jet head** designed for drop-on-demand applications. This invention features elongated members made from piezoelectric material that create multiple elongated channels for ink. Electrodes are strategically placed within these channels to facilitate the selective jettisoning of ink through nozzle holes, allowing for high precision in printing tasks. The channels not used for ink storage are termed as "dummy channels," optimizing the design for functionality and efficiency.

His second patent, **ink jet head with dummy slots**, further innovates on the first. This invention introduces elongated barriers mounted on an insulating base to form slots, each of which includes nozzle holes communicating with these slots. By applying voltage to the barriers, deflection occurs to control the ink jetting process. To ensure uniform ink intensity across the print area, the design incorporates dummy slots outward of the main active slots.
