Latest Patents

Shimizu's latest patents include advancements in inkjet head technology. One of his inventions features an ink jet head block where ink is reserved in a cartridge case. This cartridge case is designed with a fixed ink jet head and an electric connecting member in a stacked configuration. The ink jet head incorporates ink supply holes that receive ink from the cartridge case, along with ink passages that lead to nozzles at the ends of these passages. The design ensures that the nozzles and ink passages are substantially perpendicular, aligning the stacking direction, ink supply direction, and ink ejecting direction. The electric connecting member is crafted from either a flexible frame or a metal lead frame, allowing for straightforward assembly by stacking the components.

Another patent describes an ink jet head that includes a nozzle plate with a nozzle extending through its thickness. This head is laminated with a base plate that has an ink supplying hole. A pressure chamber connects the nozzle and ink supplying hole in a perpendicular manner, featuring a pressure mechanism on the bonded surface. The design minimizes the risk of bonding materials flowing into thin areas during the bonding process, thus enhancing the efficiency of ink ejection and improving print quality.
