    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.

    摘要： An ink jet printhead body has an ink filter structure (56,84) integrally incorporated therein and operative to filter ink flowing into its internal ink receiving channels (40) disposed between piezoelectrically deflectable interior wall portions of the body. In various illustrated embodiments of the printhead, the filter structure (56,84) is defined by a series of photoetched micro filter passageways (58,86) formed integrally in an outer side portion of the printhead body, a filter cavity formed in the outer side portion and receiving a separate photoetchable filter member in which photoetched micro filter passageways (58,86) are formed, and a filter cavity (80) formed in the outer side portion and receiving a separate mesh-type micro filter member. In an embodiment of the printhead (10) adapted for use with phase change type ink, a heating channel (88) is interiorly disposed within the outer body side portion and operatively receives an electrical resistance heating wire (96) used to heat phase change type ink disposed within the ink receiving channels (40) in the printhead body.

    摘要： A first surface of a first metal component of an ink jet print head is bonded to a second surface of a second metal component of the ink jet print head, the first and second surfaces being of materials having the same or similar coefficients of thermal expansion. A layer of filler material is electroplated or otherwise placed on at least one of these surfaces. The filler material has a melting point which is below the melting point of the first and second components, and the total thickness of the filler material on the surfaces together is in the range of from approximately one-sixteenth micron to approximately five microns, with one-eighth micron to two microns being a preferred range. These surfaces are placed together and subjected to heat and pressure to diffusion bond the surfaces without melting the filler material. The diffusion bonding is performed in one approach until no more than approximately one micron of filler material remains between the surfaces. Thereafter, the filler material is melted without melting the first and second components to thereby braze the first and second components together.
