    摘要: Apparatus for controlling ink in an ink jet printer includes an ink delivery channel; a source of pressurized ink communicating with the ink delivery channel; a nozzle bore which opens into the ink delivery channel to establish an ink flow path, the nozzle bore defining a nozzle bore perimeter, inherent surface tension of pressurized ink in the nozzle bore forming an ink meniscus; and a selectively-actuated heater associated with the nozzle bore to cause a reduction in the surface tension of the ink when activated such that ink flows from the nozzle bore in a continuous stream substantially for the duration of activation of the heater only.

    摘要: A device for coupling light from a laser diode (12,25,27,33,34,60,93) to an optical fiber (16,12,19,44,64,95) is provided. The device utilizes two opposed mirrors (22,24,35,50,52,74,76,84,86,94,96) to redirect the divergent light beam (10) of the laser diode to within the smaller numerical aperture or angle (14) of acceptance of the optical fiber. The two opposed mirrors can be, for example, concave elliptical mirrors, a convex spherical and a concave spherical mirror, or a planar mirror and a concave spherical mirror. Each mirror has an aperture (46,48,66,68) therein to allow passage of the initial laser diode beam or the redirected beam to the optical fiber.

    摘要: Disclosed is a color silver halide photographic element comprising a light-sensitive silver halide emulsion layer or a non-silver containing light-insensitive layer, said light-sensitive or light-insensitive layer containing a polymer compound comprising a heterocycle unit derived from:

    (a) a heterocycle monomer (1) comprising two or more annulated rings containing, in total, a minimum of three ring heteroatoms of which no more than two of the heteroatoms are connected in sequence to each other and (2) having a ClogP less than 6.2; or
    (b) a monocyclic heterocycle monomer having exactly three ring heteroatoms and having a ClogP less than 8.75;


    with the proviso that the heterocycle unit does not contain a hydroxy or mercapto group (or their tautomeric equivalent), and does not react with oxidized developer; and
    the amount of the polymer compound in the element being sufficient to increase the photographic speed of the element compared to the same element without the compound.
