  • Patent number: 7306849
    Abstract: A probe cleaning system automatically detects a surface of a probe cleaning device during a cleaning process by providing a predetermined finish on the surface of the probe cleaning device. The predetermined finish can include a textured or machined finish or a marking, such that the predetermined finish provides contrast against the surface. Cameras in the system automatically focus on the surface, with the predetermined finish. This in-focus condition is related to a distance between probes and the surface. Once an in-focus condition is determined, the system performs an automated cleaning process by interacting the probes with the probe cleaning device.

    Abstract: The invention is a patch system for repairing collapsible fuel tanks, water tanks, inflatable boats, and other articles fabricated from a flexible structural fabric coated with a polymer. The coated structural fabric is made of nylon or polyester synthetic fibers or a blend thereof, which are coated with a thermoplastic elastomer. The structural coated fabric is coated with a thermoplastic elastomer that is a urethane (TPU), or a TPU alloy polymer. Likewise, the patch is a urethane adhesive having a latent cure coated on a TPU film. The patch can also have an integral reinforcing fabric for applications requiring a higher tensile patch. In the invention, the urethane adhesive of the patch is solvent activated by the application of a thin coating of a volatile, substantially low odor, fugitive solvent like acetone or MEK. While in the activated state, the adhesive has much less cyrstallinity and a lot more tack.

  • Patent number: 7306869
    Abstract: A wide-area electrostatically-actuated shutter is provided that includes a thin, flexible, diaphragm that is placed between two rigid electrode structures. In one embodiment of the invention, the diaphragm has a set of openings in it. These openings overlap with corresponding openings in one of the rigid electrodes such that when the diaphragm is contiguous to that electrode, the openings provide apertures through which vaporous fuel can flow. The opposite electrode does not have overlapping openings, thus it forms a seal that prevents gas or vapor from passing through it when the diaphragm is in contact with the opposite electrode. The shutter is actuated electrostatically by an associated driver that applies a voltage to the diaphragm such that when the high voltage is applied to the diaphragm, the diaphragm is attracted to the fixed electrode that is tied to ground.

  • Patent number: 7306889
    Abstract: A process for producing a toner by subjecting a polymer and a resin component containing a cross-linkable polymer capable of cross-linkingly reacting with the polymer, to cross-linking reaction in the presence of a first wax to form a wax-containing cross-linked polymer composition; mixing the wax-containing cross-linked polymer composition with at least a colorant and a second wax, followed by melt-kneading to form a toner composition; and pulverizing the toner composition to produce toner particles. Also disclosed is a toner produced by this process. The toner thus obtained is a toner whose fixing performance and anti-offset properties are well balanced and also which makes it possible to afford images having less fog and high quality, over a long period of time in environments of from low temperature and low humidity to high temperature and high humidity, and is highly durable without causing any contamination of members with which the toner comes into contact.
