Title: The Innovative Contributions of Der-Rong Shyn
Introduction
Der-Rong Shyn is a notable inventor based in Putz, Taiwan. He has made significant contributions to the field of fluid injection devices, holding a total of 3 patents. His work has been instrumental in advancing technology related to inkjet printers and fluid actuation systems.
Latest Patents
One of his latest patents is focused on methods for fabricating fluid injection devices. This innovative process involves forming a patterned sacrificial layer on a substrate, followed by the creation of a patterned first structural layer that covers the sacrificial layer. Additionally, at least one fluid actuator is formed on the structural layer, and a first passivation layer is applied over the actuator. The process continues with the formation of an under bump metal (UBM) layer and a patterned first photoresist at predetermined sites. The patent outlines a detailed etching process that ensures the effective functioning of the fluid injection devices.
Another significant patent by Shyn is a pressure-compensation device designed for inkjet printer cartridges. This device includes an accumulator bag, a resilient element, and a motion element. The accumulator bag communicates with the external atmosphere, while the resilient element maintains a stable tension state to regulate backpressure within the cartridge. This innovative design allows for consistent performance as the ink is consumed, ensuring a stable backpressure is maintained.
