Lorentz diaphragm electromagnetic ink jet printing mechanism

摘要

This patent describes an ink jet printer having a nozzle chamber with one wall of the chamber comprising a moveable diaphragm actuated by means of a Lorenz force so as to cause the consequential ejection of ink from the ink ejection chamber. The diaphragm can include an embedded conductive coil and is of a corrugated or concertinaed form such that it expandable by concertinaing upon actuation. The diaphragm can be formed through utilisation of an appropriately half-toned mask utilizing silicon fabrication techniques.
