Introduction

Tokio Tatsumi is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of liquid jet technology, holding a total of 3 patents. His work focuses on methods of manufacturing liquid jet heads, which are essential components in various applications.

Latest Patents

One of his latest patents is a method of manufacturing a liquid jet head. This method includes a through hole forming step, where through holes are created on a base plate. It also involves an actuator plate bonding step, where actuator plates are bonded to opposite sides of the base plate. Additionally, an electrode forming step is included, which involves forming electrodes on the bonded base plate and actuator plates. In the through hole forming step, the inner surfaces of the through holes are roughened. In the electrode forming step, second extraction electrodes are routed to a principal surface of the base plate through the through holes.

Another significant patent by Tatsumi is related to a liquid jet head, method for manufacturing a liquid jet head, and liquid jet apparatus. This invention features a base plate and an actuator portion fixed to the base plate, which has an array of alternating ejection channels and dummy channels. Drive electrodes are formed on the inner surfaces of these channels, while extracting electrodes are formed on the base plate's rear side and are electrically connected to the drive electrodes. Notably, the electrode formation region of the base plate, where the extracting electrodes are formed, has a surface roughness greater than that of other regions.
