Title: The Innovative Contributions of Yoshiyuki Shiratsuki

Introduction

Yoshiyuki Shiratsuki is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of recording technology, holding a total of 13 patents. His work focuses on innovative methods for ejecting liquid drops and enhancing ink-jet recording apparatuses.

Latest Patents

One of his latest patents is a recording element and recording device that can stably eject very fine liquid drops without nozzles. This invention operates with low frequency and low voltage driving. The design includes vibrators on a substrate, with elastic members that have tips in various forms, such as sharpened, plate-like, or needle-like. The free surface of the liquid is positioned closer to the bottom side of the elastic members than the tips, allowing for effective driving of the vibrators with external means.

Another notable patent involves a method and apparatus for redirecting propagating acoustic waves. This ink-jet recording apparatus jets an ink droplet from a free surface of an ink material by utilizing surface acoustic waves. The apparatus features a substrate with a slant face that contacts the ink material. A vibration generator is also included, which generates multiple surface acoustic waves that are transformed into longitudinal waves within the ink material, concentrating their propagating directions at a specific portion.
