  • Patent number: 6199938
    Abstract: Disclosed is a sliding door locking device for a vehicle. The sliding door locking device for a vehicle comprises a striker secured to a sliding door to be integrally reciprocated along with the sliding door; a housing fastened to a body of the vehicle and having a slot into which the striker is inserted when the sliding door is closed; and a latch lock pivotally fixed to and inside the housing and having an engaging piece which is connected with a fuel filler lid through a cable, the latch lock being formed with a latch groove which functions to prevent the striker inserted into the slot of the housing from being moved out of the slot when the fuel filler lid is opened, thereby locking the striker inside the slot.

  • Patent number: 5981640
    Abstract: A laser markable Acrylonitrile-Butadiene-Styrene (ABS) terpolymer formulation suitable for a number of applications and in particular, telecommunications terminals and keypads. The ABS terpolymer comprises Acrylonitrile (20-24%), Butadiene (14-17%), Styrene (59-63%), Medium Color Furnace Black (0.008-0.015 PPH), Iron Oxide Red (0.003-0.005 PPH), Titanium Dioxide (0.6-3.50 PPH), Silicon Dioxide (0.07-0.2 PPH), Zinc Carbonate (0.05-0.70 PPH) and Aluminum Hydroxide (0.05-0.25 PPH). The ABS so produced is characterized by desirable performance characteristics, e.g., mechanical strength, impact resistance, gloss, stain resistance, molding processing properties and color, as defined in a 3D color system of the color value (L-star (=67.53)), hue (a-star (=1.15)), chroma (b-star (=3.46)).

  • Patent number: 5837380
    Abstract: A substantially warp-free laminate polymeric film structure is obtained by a fabrication process in which the individual layers of polymeric film that are to be laminated together to form a card or similar structure are selected such that the mechanical properties of one layer or pair of layers are offset by those of another layer or layer pair wherein each polymeric film layer is bonded to its adjacent polymeric film layers by adhesive layers wherein the adhesive layers have a tack point temperature that is within 10.degree. C. of the glass transition temperature of said polymeric film layers. The properties of the layers which may be subject to this consideration include, for example, the layer thickness, tensile strength, elongation factor, shrinkage rate, and machine processing direction.
