Title: Ink jet printer - has improved jet repetition capability and uses pressure bubbles resulting from heating ink to transform into print jet
Inventor: BUEHLER KARL DIPL ING
IPC: B41J2/14
Filed: 1990-05-22
Abstract: The device comprises a sandwiched layer (25) made of relatively good heat conducting material (Si, or a  metal) acting as the carrier of a heating element (26), either on one side or on both sides of the sandwiched layer (25) which thus directly heat ink fluid present in the duct space (24) (or 24 and 25). Pressure bubbles which develop as a result of heat input drive ink fluid through an opening (28) in the substrate layer (25), transform it into a print jet. The lost liquid is replaced through a duct opening (28); the heat is quickly dissipated through the sandwich layer. The rate of ink : replacement and heat dissipation conjointly determine the rate of jet repetition, e.g. print speed. ADVANTAGE - Print features are variable by applying heater current pulses to upper and lower ducts either  synchronously or out of phase, or only to one or other.
