Latest Patents

The provided information lists 1 patent for Yushi Kitase: “Circulation Unit, Liquid Discharge Head, and Liquid Discharge Apparatus.” The invention describes a circulation unit with two pressure adjusters, each using a valve chamber, a pressure control chamber, a communication port, a valve, a flexible member, and a pressure plate. The valves respond to pressure conditions in their respective pressure control chambers. In the second pressure adjuster, the pressure plate and valve make contact below a specified pressure threshold. The thresholds are designed so that this contact occurs before the pressure difference reaches the level needed to begin printing after a circulation pump resumes operation.

Career Highlights

Kitase’s listed patent reflects work on pressure regulation and liquid circulation in discharge equipment. The design addresses how pressure adjusters respond when a circulation pump stops and restarts, with the aim of controlling the conditions before printing resumes.
