Title: Gerald E Heppell: Innovator in Ink Jet Technology
Introduction
Gerald E Heppell is a notable inventor based in Tigard, Oregon. He has made significant contributions to the field of ink jet technology, holding a total of 3 patents. His work has been instrumental in advancing the functionality and durability of ink cartridges.
Latest Patents
One of Heppell's latest patents is for an ink jet cartridge with integrated circuitry. This innovative design features an ink jet pen with a body that defines an ink chamber. The print head on the pen body communicates with the ink chamber, and the pen body includes electrically conductive traces that extend from a printer interface region to the print head. The print head may be surface mounted to the body or connected with anisotropic or Z-axis conductive adhesive. The traces can be conductive material applied into grooves on the surface of the body or an insert molded leadframe. The interface region and print head may be located on a common surface of the body.
Another significant patent is for a printhead structure and method for producing the same. This high-durability printhead is designed for an ink cartridge printing system. It includes a substrate with ink ejectors, such as resistors, and an orifice plate positioned above the substrate. The orifice plate, preferably made from a non-metallic polymer film, has multiple openings to enhance its functionality. To improve durability, a protective coating is applied to the surfaces of the orifice plate, which may involve dielectric compositions or metal layers. This innovative approach enhances the abrasion and deformation resistance of the plate, addressing common issues like 'ruffling' and 'dimpling'.
