  • Microattachment of optical fibers
    Patent number: 4788406
    Abstract: One or more optical fibers are attached to an optical component element or supporting substrate by coating the peripheral surface of the optical fiber with a metallic layer and then positioning the metallic layer in electrical contact with a metal surface of the object along an interface. An electrical current pulse or pulses is applied through the interface sufficient to cause local melting or near melting and welding at the interface.
    Type: Grant

  • Composite ink jet drivers
    Patent number: 4449134
    Abstract: An ink jet droplet exciter for generating pressure waves in a droplet generator. The preferred exciter is a composite made of PZT, Pb (Zr:Ti) O.sub.3, and a polyethylene supporting material. The mean diameter of the PZT particles is 7 mils and the entire exciter thickness is between 10 and 12 mils. The composite is pliable and can be made in sheets of a large enough area to provide droplet excitation for a multiple nozzle generator.

  • Ink jet method and apparatus using a thin film piezoelectric excitor for drop generation with spherical and cylindrical fluid chambers
    Patent number: 4296417
    Abstract: A thin film of polyvinylidene fluoride is operated in the piezoelectric thickness mode to stimulate fluid drop formation for ink jet printing systems. The film is placed against a rigid wall of either rectangular, cylindrical or spherical chambers having at least one nozzle for emitting a continuous stream of fluid from which the drops are formed. The frequency of the drop generation is related to the frequency of an AC voltage applied across the piezoelectric film.
