发明名称 Single element transducer for an ink jet device
摘要 The ink ejecting portion of an ink jet printer is described, wherein a single ceramic transducer is used to create the pressure for the ink droplets. Unlike prior devices, the transducer is a one-piece member as opposed to use of a crystal and diaphragm. The one-piece member is practical because of the generally spherical configuration of the crystal.
