Latest Patents

Higuchi's latest patents include a nozzle plate, a method for manufacturing the nozzle plate, a droplet discharge head, and a droplet discharge device. The nozzle plate features a nozzle designed for discharging liquid as droplets, along with a liquid-repellent film that minimizes droplet attachment on one surface. Additionally, it incorporates a first bonding film on the opposite surface, which is bonded to a substrate. The liquid-repellent film consists of a first plasma polymerized film with a silicon skeleton, characterized by siloxane (Si—O) bonds and a random atomic structure, along with an elimination group attached to the silicon skeleton.

The droplet ejection head comprises a substrate with first through-holes that form reservoir chambers and a second through-hole that creates a supply chamber. It also includes a nozzle plate with nozzles for ejecting liquid and a second bonding film. The bonding films contain an Si-skeleton made of silicon atoms, with siloxane (Si—O) bonds and elimination groups bonded to the silicon atoms. This innovative design enhances the efficiency and effectiveness of droplet ejection.
