Latest Patents

One of Hiroshi Arai's latest patents is a method of manufacturing a piezoelectric vibration element for an inkjet recording head. This innovative method involves alternately laminating conductive layers and piezoelectric material layers. After the layers are laminated to a predetermined thickness, the laminated structure is sintered. External connection electrodes are then formed on the surfaces of the sintered structure. Arai's method also includes fixing a non-vibration region of the sintered structure onto a fixing plate. The structure is then cut into drive piezoelectric vibration elements and dummy piezoelectric elements based on the presence of conductive layers.
