摘要： A fluid drop dispenser is fabricated from an injection moldable plastic and includes inner and outer components each having an end wall and an axially extending cylindrical wall that define a respective counterbore for each component. The inner component is assembled to the outer component with the respective outer and inner axially extending walls defining an annular fluid receiving chamber therebetween. A nozzle is provided in the outer wall through which drops are ejected on demand. A piezoelectric actuator disc is mounted within the inner component with its periphery bonded to the cylindrical wall of the inner component. When the actuator disc is electrically excited, it undergoes a radially outward expansion to cause a predetermined quantity of fluid to be ejected from the annular chamber through the nozzle.

摘要： An air-assisted drop-on-demand ink jet head l0 has a single compartment ink chamber l4 and is designed for operation over a wide range of ink drop repetition rates, including extremely high repetition rates, such as twenty kilohertz. The components included in the ink jet head have natural resonance frequencies which are greater than the desired maximum drop generation frequency of the ink jet head. In addition, the natural frequency of each of the components of the ink jet head are sufficiently different from one another to prevent intercoupling. Ink is supplied to the ink chamber l4 via a supply inlet passageway 38 which has a cross-sectional area which is sized large enough to allow the supply of ink to the ink chamber. Yet, this area is small enough so that the natural frequencies of ink in the ink inlet do not significantly alter drop generating pressure pulses in the ink chamber l4.

摘要： An air assisted drop-on-demand ink jet head 10 has an ink chamber with an ink drop-forming orifice outlet 23 from which ink drops are generated in response to pressure waves caused by the piezoelectric crystal 56. The ink drops are carried by air outwardly through an external orifice 24 and toward printing medium. The internal orifice outlet 23 is centered in a projecting structure 48 which extends toward the external orifice 24. In one form, the projection 48 is of a frustoconical or mesa-like shape. Air flowing past the top of the projection prevents ink from wetting anything but the top of the projection, resulting in highly uniform ink drop formation with a single uniform dot being produced on the printing medium in response to each pressure wave.

摘要： An inkjet head includes a pressure chamber and a piezoelectric device. A cross-sectional shape of the pressure chamber in a direction substantially perpendicular to the up-down direction includes a circular-arc-shaped side wall portion formed on the ink supply side, and linear side wall portions forming such a shape that the distance between the linear side wall portions gradually decreases toward the side opposite to the supply side. The piezoelectric device includes a displacement portion and an electrode connection portion. A cross-sectional shape of the displacement portion in the direction substantially perpendicular to the up-down direction includes a circular-arc-shaped portion formed inside the circular-arc-shaped side wall portion and having a smaller cross section in the direction substantially perpendicular to the up-down direction than a corresponding cross section of the shape formed by the circular-arc-shaped side portion, and a linear portion formed inside the linear side wall portions and having a smaller cross section in the direction substantially perpendicular to the up-down direction than a corresponding cross section of the shape formed by the linear side portions. The electrode connection portion is connected to the linear portion on the side opposite to the circular-arc-shaped portion in such a position as to overlap with a side wall portion of the pressure chamber in the up-down direction.

摘要： A fluid drop dispensing device (10), particularly suited for ink jet printer heads, in which a circular electroactuator (22) is supported in concentric relationship with inner (14) and outer (12) ring members defining an annular chamber (16) which is reduced in volume upon excitation of the electroactuator (22). The chamber is defined as a peripheral groove in one or the other of the inner and outer rings and is rendered fluid tight exclusively by peripheral ring surface contact maintained by hoop stress in the two rings as a result of press fitting the inner ring into the outer ring. Both rings may be of plastic material selected for appropriate characteristics or in the alternative, the outer ring may be of plastic while the inner ring is metallic and fabricated of stainless steel or nickel, for example.

The driving element includes a first electrode disposed on a second surface of the diaphragm, a second electrode opposing the first electrode, and a piezoelectric body interposed between the first electrode and the second electrode. In addition, an inter-wiring insulating film that covers the second surface of the diaphragm and the driving element, and an extracting electrode which is on the inter-wiring insulating film, are further provided. The inter-wiring insulating film includes a contact hole that exposes a part of the second electrode and through which the second electrode and the extracting electrode contact each other. The contact hole is disposed at a position which aligned with a solid portion of a circumferential wall of the pressure chamber in the base.
