摘要： PROBLEM TO BE SOLVED: To provide a defoaming member for an ink-jet head which can print with a high resolution and can be inexpensively and easily manufactured in a simple structure. SOLUTION: The defoaming member is constituted of a tubular member 129 which is inserted to an ink channel in the ink-jet head and is formed of a material which passes the air without passing ink. One end of the tubular member 129 is sealed and the other end is connected to a negative pressure source.

摘要： In the particular embodiment of an ink deaerator described in the specification, an elongated ink path leading to an ink jet head is formed between two permeable membranes. The membranes are backed by air plenums which contain support members to hold the membranes in position. Reduced pressure is applied to the plenums to extract dissolved air from the ink in the ink path. Increased pressure can also be applied to the plenums to eject ink from the ink jet head for purging. Within the ink jet head ink is circulated convectively from the orifice to the deaerating path even when the jet is not jetting ink.

摘要： Deaeration of Ink in an Ink Jet System An object of the invention is to provide a new and improved method and apparatus for eliminating dissolved air from ink in an ink jet system which overcomes the above-mentioned disadvantages of the prior art. Another object of the invention is to provide a system for deaerating ink in an ink jet system and for purging any air bubbles which have been formed in the ink jet head. In the ink deaerator described in the specification, an elongated ink path (27) leading to an ink jet head (11) is formed between two permeable membranes (30, 31). The membranes (30, 31) are backed by air plenums (32, 33) which contain support members (34) to hold the membranes in position. Reduced pressure is applied to the plenums to extract dissolved air from the ink in the ink path (27). Increased pressure can also be applied to the plenums (32,33) to eject ink from the ink jet head (11) for purging. Within the ink jet head ink is circulated convectively from the orifice (35) to the deaerating path (27) even when the jet is not jetting ink.

摘要： In the representative ink supply system described in the specification, continuous circulation of ink in an ink jet head is accomplished by providing two reservoirs connected to each ink jet orifice (11) through corresponding passages (40,15,13,42) so that ink flows continuously from a high-level reservoir past the orifice to a low-level reservoir. The difference between the levels of ink (45,46) in the reservoirs is maintained relatively constant by inertial pumping during reciprocal motion of the ink jet head or by pressure transfer of ink from one reservoir to the other reservoir. Cross-flow purging of air or debris from the ink jet head is effected by covering the ink jet orifices (11) and applying air pressure to one reservoir to cause ink and any trapped air or debris to flow from the head to the other reservoir. A pump responsive to reciprocal motion of the ink jet head generates a positive air pressure which is applied during purging and a negative air pressure which is applied to a deaerator for removing dissolved air from the ink.

摘要： In the embodiments of the simplified ink jet head described in the specification, a carbon body is formed with ink passages, such as internal passages (19, 21, 25) extending through a carbon plate (26), pressure chambers (2) on one side of a carbon plate (26), flow-through passages (24) on the other side of the same plate and ink supply passages (19, 25), and a piezoelectric plate (23) is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive. The piezoelectric plate (23) may have a conductive coating on one side which is photo-etched to produce an electrode pattern corresponding to the pattern of the pressure chambers in the carbon plate. An orifice plate (13) may have specially profiled orifice openings (12) to assure axial projection of drops and may be affixed by a thin layer of epoxy adhesive to a carbon plate (26) having orifice passages (21) supplying ink from the pressure chambers (20) to the orifices (12). Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate (23) and, to assure grounding of the piezoelectric plate, a conductive epoxy adhesive may be used to bond the piezoelectric plate to the carbon plate. Moreover, since the carbon plate is porous, it can provide a communication path (76) between a vacuum source (77) and an air-permeable, ink-impermeable layer (75) on the ink passages to remove dissolved air from the ink in the passages. In one alternative embodiment, an ink jet head assembly contains two separate carbon pressure chamber plates, a carbon manifold plate and a carbon collar to retain the carbon plates in an assembly.
