Title: Shuichi Yayaguchi: Innovator in Ink Jet Technology
Introduction
Shuichi Yayaguchi is a notable inventor based in Nagano, Japan. He has made significant contributions to the field of ink jet technology, holding a total of 3 patents. His work focuses on improving the efficiency and effectiveness of nozzle plates used in ink jet recording apparatus.
Latest Patents
Yayaguchi's latest patents include a method of preparing the nozzle plate. This innovative method involves coating the entire part of the rear surface of a nozzle plate, excluding the peripheral portions of the nozzle holes, with a resist tape. The nozzle plate is then immersed in an electrolytic solution containing metal ions and water-repellent resin particles. This process results in a plating that enhances the nozzle plate's performance. The plated nozzle plate is subsequently heated to a temperature above the melting point of the water-repellent resin, creating a eutectoid plating layer that suppresses deviation of ink droplet passages due to wetting.
Another significant patent by Yayaguchi is for a nozzle plate specifically designed for ink jet recording apparatus. This patent shares similar methodologies as his previous work, emphasizing the importance of the eutectoid plating layer in maintaining the precision of ink droplet delivery.
