  • Patent number: 4860048
    Abstract: An image forming apparatus includes movable image bearing member, a first charger means for charging the image bearing member, first electrostatic latent image forming device for forming a first electrostatic latent image in accordance with image information on the image bearing means charged by the first charger, first developing device for developing the first electrostatic latent image, a second charger for re-charging the image bearing member, second electrostatic latent image forming device for forming a second electrostatic latent image in accordance with image information on the image bearing member recharged by the second charger, second developing device for developing the second electrostatic latent image, a dector for detecting a surface potential of the image bearing member, the detector detecting at least the surface potential at that portion of the latent image formed on the image bearing member by the first latent image forming device which is developed, after the portion is charged by the seco

  • Patent number: 4417024
    Abstract: Fiber-treating compositions are described which durably provide water repellency and oil repellency for the treated fiber. These compositions comprise a siloxane component bearing fluorinated hydrocarbon radicals, unsubstituted hydrocarbon radicals and silicon-hydride atoms, and a dehydrogenation condensation catalyst. Curing of the compositions occurs by a dehydrogenation condensation reaction between the silicon-hydride atoms and/or between the silicon-hydride atoms and the hydroxyl radical of an optionally added hydroxyl-endblocked organopolysiloxanes.

  • Patent number: 4355149
    Abstract: Fiber-treating compositions are described which durably provide water repellency and oil repellency for the treated fibers. These compositions comprise a cyclic siloxane bearing fluorinated hydrocarbon radicals and silicon-hydride atoms, and a dehydrogenation catalyst. Curing of the compositions occurs by a dehydrogenation condensation reaction between the silicon-hydride atoms and/or between the silicon-hydride atoms and the hydroxyl radicals of an optionally added hydroxyl-endblocked organopolysiloxane.
