  • Publication number: 20060228639
    Abstract: Toners including a low melt wax and a carnauba wax are described. The toners include at least one binder, at least one colorant, at least one wax having a melting point of 135° C. or less, and a compatibilizer wax (e.g., carnauba wax). The low melt wax is preferably polyethylene wax. Images may be formed with the toners in an image forming process including steps of depositing the toner onto a latent image of an imaging member to form a toner image, transferring the toner image to an image receiving substrate, and fusing the toner image. During the fusing, the at least one wax and the compatibilizer wax exude from the toner, forming a stripping enhancing layer upon the toner image. Thus, fuser roll stripping performance is enhanced.

  • Publication number: 20060088348
    Abstract: A fast acting fusing method and apparatus are provided for (a.) first moving a certain quantity of working liquid within a fusing heat pipe device from a heat transferring region of the fusing heat pipe device to an induction heating region of the fusing heat pipe device for maximizing liquid-to-device wall contact area within the induction heating region; (b.) using inductor heating coils to apply heat to the induction heating region of the fusing heat pipe device for heating the working liquid within the induction heating region; (c.) allowing heated vapors from the working liquid being heated within the induction heating region to move into the heat transferring region of the fusing heat pipe device for heating the heat transferring region; (d.) using a controller to compare heating of the heat transferring region of the fusing heat pipe device to a given heating value; and (e.

  • Patent number: 7013253
    Abstract: A method and apparatus for identifying potential noise failures in an integrated circuit design is described. In one embodiment, the method comprises locating a victim net and an aggressor within the integrated circuit design, modeling the victim net using two ?-type resistor-capacitor (RC) circuits, including determining a coupling between the victim net and the aggressor, and indicating that the integrated circuit design requires modification if modeling the victim net indicates that a potential noise failure may occur in the integrated circuit design.

  • Publication number: 20050130284
    Abstract: The present invention relates to diacylglycerol acyltransferase genes and proteins, and methods of their use. In particular, the invention describes genes and proteins that exhibit both long-chain acyltransferase and acetyltransferase activity. The present invention encompasses both native and recombinant wild-type forms of the transferase, as well as mutants and variant forms, some of which possess altered characteristics relative to the wild-type transferase. The present invention also relates to methods of using diacylglycerol acyltransferase genes and proteins, including in their expression in transgenic organisms and in the production of acetyl-glycerides in plant oils, and in particular seed oils.

  • Patent number: 5981720
    Abstract: Isolation of the salivary basic glycoproteins CON-1 and CON-2 in high purity and without substantial loss of activity was achieved in a method utilizing two denaturing steps which limit proteolysis. Cloning of CON-1 and CON-2 from the PRB2 and PRB1 genes also provides a recombinant source of the proteins, which are useful inhibitors of alpha-glucosidases in the treatment of diabetes and in preventing retroviral infection. Subfragments of CON-1 and CON-2 having alpha-glucosidase inhibitory activity are identified which can be prepared synthetically in commercial-scale quantities.

  • Patent number: 5331108
    Abstract: A maize plant has in its genome a non-mutable form of a mutant allele designated vitX-8132. The allele is located at a locus designated as glt which conditions kernels having an altered starch characteristic. Maize plants including such a mutant allele produce a starch that does not increase in viscosity on cooling, after heating.
