Title: Syuzo Matsumoto: Innovator in Ink Jet Technology

Introduction

Syuzo Matsumoto is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of ink jet technology, holding a total of 6 patents. His innovative designs have advanced the capabilities of ink jet printers, making them more efficient and reliable.

Latest Patents

One of Matsumoto's latest patents is for an ink jet head that utilizes a grooved piezo-electric element. This design features a plurality of grooves, diaphragms, and actuators. The actuator, along with two grooves on either side filled with stuffing material, effectively covers corresponding passages. This configuration prevents interference issues even when the stuffing material shifts during operation. As a result, the flexure force of each actuator is transmitted to the corresponding passage, allowing for precise ink jetting through the nozzle.

Another notable patent is for a liquid jet recording head. This invention includes a flow path member with multiple flow paths, each having an opening surface. The piezo-electric member consists of several grooves and piezo-electric elements, which are strategically positioned to face the openings of the flow paths. An elasticity member fills each groove, and a liquid guide mechanism directs liquid from an external supply to the flow paths, ensuring efficient operation.
