Title: Innovations of Yohji Ara
Introduction
Yohji Ara is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of printing technology, holding a total of 11 patents. His work focuses on enhancing the efficiency and functionality of inkjet printing systems.
Latest Patents
One of his latest patents is an inkjet printing apparatus designed to improve the printing process by supplying ink from a main tank to a sub tank. This apparatus allows for an agitating operation that effectively eliminates sedimentation of pigment components without complicating the structure or increasing costs. The design includes a diaphragm in the ink supply path, along with a driving mechanism that alters the internal volume of the diaphragm. This innovation ensures that the resistance value of the flow path from the diaphragm to the printing head is greater than that from the diaphragm to the sub tank, facilitating bidirectional ink flow to prevent sedimentation.
Another notable patent involves a printhead that features a first ink chamber with an inlet port for ink supply, a second ink chamber, and a discharge orifice for ink ejection. The printhead is equipped with an air-liquid separation unit that restricts liquid ejection, enhancing the overall performance of the printing apparatus. The flow resistance from the inlet port to the first outlet port is designed to be smaller than that to the second outlet port, optimizing the ink delivery process.
