    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 extending through a carbon plate, pressure chambers on one side of a carbon plate, flow-through passages on the other side of the same plate and ink supply passages, and a piezoelectric plate is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive. The piezoelectric plate 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 may have specially profiled orifice openings to assure axial projection of drops and may be affixed by a thin layer of epoxy adhesive to a carbon plate having orifice passages supplying ink from the pressure chambers to the orifices. Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate 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 between a vacuum source and an air-permeable, ink-impermeable layer 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.

    摘要: In the embodiments of the simplified ink jet head described in the specification, a carbon plate is formed with orifice passages extending through the plate, pressure chambers on one side of the plate, flow-through passages on the other side of the plate and ink supply passages, and a piezoelectric plate having a conductive coating on the exposed side is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive. The conductive coating on the piezoelectric plate is photo-etched to produce an electrode pattern corresponding to the pattern of the pressure chambers in the carbon plate, and an orifice plate is affixed by a thin layer of epoxy adhesive to the opposite surface of the carbon plate with orifices aligned with the orifice passages in the carbon plate. Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate and, since it is porous, it can provide a communication path between a vacuum source and an air-permeable, ink-impermeable layer on the ink passages to remove dissolved air from the ink in the passages. In one alternative embodiment, the orifice passages are formed in an edge of the plate and, in another alternative embodiment, a large plate is provided on one surface with a number of adjacent piezoelectric plates.

    摘要: A logic module system utilizing a spring energy storage means having a spfic threshold level response and a constant force over a specific displacement in cooperation with a plurality of cams adapted to be moved by external forces, such as ram-air pistons, rate controlled springs, or the like. Each individual cam is profiled to present a control surface to a cooperating plunger at specified time intervals or "windows." If the combined control surfaces present at any instant in time correspond to a predetermined sequence, the system will move to an ARM condition. Absent the proper arrangement of the "windows," the system will be returned and locked in a SAFE condition.
