Title: Junya Hayasaka: Innovator in Liquid Discharge Technology
Introduction
Junya Hayasaka is a prominent inventor based in Funabashi, Japan. He has made significant contributions to the field of liquid discharge technology, holding a total of 4 patents. His work primarily focuses on methods for manufacturing substrates used in liquid-ejection heads.
Latest Patents
One of his latest patents is titled "Method for manufacturing liquid-discharge-head substrate." This innovative method involves providing a substrate that contains an energy-generating element and a pad. The pad features a wiring layer and a contact-probe receiving section, which has a Vickers hardness greater than that of the wiring layer. The process includes bringing a contact probe into contact with the receiving section and performing an electrical inspection by contacting the wiring layer. Another notable patent is "Method for producing liquid-ejection-head substrate and liquid-ejection-head substrate produced by the same." This method also involves a substrate with an energy-generating element and a pad, where the wiring layer has both relatively thick and thin portions. Electrical inspection is performed by applying a contact probe to the thinner portion of the wiring layer.
