  • Patent number: 6344161
    Abstract: Segmentation of a flexible, elongated, strip-shaped substrate having a plurality of encapsulated semiconductor devices mounted thereon, for device singulation, is facilitated by pre-cutting pairs of slots through the substrate at each device mounting area, which slots minimize the amount of substrate material required to be removed during device singulation. Disadvantageous penetration of the slots by liquid encapsulant material is substantially prevented, or at least minimized, by forming slots having burrs or flaps at the upper, mounting surface of the substrate which seal off, or substantially reduce the width of the slots.

  • Patent number: 6342175
    Abstract: A pumpkin carving kit includes a cutting die having a closed peripheral configuration defining a shape to be carved into the pumpkin shell, a striking tool for driving the die into the pumpkin shell, and a scoop and scraping tool. The die has a lower cutting edge and an upper driving edge, and a striking surface of the striking tool has a lateral dimension which is greater than the majority of the largest transverse dimension of the striking edge to uniformly distribute impact force to the die. Serrations of the cutting edge of the die are forced into the pumpkin shell to hold the die in position before it is struck. The scoop and scraping tool is used to scrape the thickness of the pumpkin wall so that the die will extend through it.

  • Patent number: 5879782
    Abstract: This invention relates to a process for forming a single-layer, durably wettable polymeric web having a plurality of apertures. This process comprises melting a mixture of at least one thermoplastic polymer and at least one migratable surfactant and extruding the mixture to form a single-layer, substantially continuous polymeric film. The film is then apertured using high pressure fluid flows. Aperture formation is conducted when the single-layer polymeric film has a contact angle of at least about 30.degree., to minimize wash-off of the surfactant impregnated in the polymer web. The invention also relates to durably-wettable apertured webs.

  • Patent number: 5851457
    Abstract: A method for making upholstered articles comprising a foam core, an integrally attached cover assembly, and an integrally attached scrim is provided. The method includes the step of positioning an air-impermeable cover assembly over a mold cavity of a molding apparatus, applying a vacuum to the fabric through a plurality of apertures in the walls defining the mold cavity to cause the fabric to conform to the shape of the mold cavity, depositing a foam precursor into the mold cavity, positioning an air-impermeable scrim over the foam, and allowing the foam precursor to expand to form the article. The method allows upholstered articles having an integrally attached cover assembly to be manufactured using a pour-in-place process which does not utilize abherents, while still preventing bonding of the foam core to the lid and/or other surfaces of the molding apparatus.

  • Patent number: 5843363
    Abstract: A process for ablation etching through one or more layers of dielectric materials while not etching an underlying conductive material layer comprises selecting parameters whereby the ablation process automatically stops when the conductive material layer is reached, or monitoring the process for end point detection of the desired degree of ablation. Parameters selected are the absorptivity of the dielectric layer versus that of the conductive material layer. End point detection includes monitoring radiant energy reflected from the workpiece or the content of the materials being ablated from the workpiece.

  • Patent number: 5833898
    Abstract: A method for manufacturing a resin-impregnated endless belt structure is carried out on an apparatus having an outer cylinder having an inner cylindrical surface coaxial with a smaller radius cylindrical mandrel. An endless base structure for the endless belt structure is disposed within the outer cylinder on the inner cylindrical surface. The cylindrical mandrel, having an inwardly curved nose, is then inserted into the outer cylinder forming a nip of converging geometry between the nose and the inner cylindrical surface. Polymeric resin material is dispensed continuously into the nip while the cylindrical mandrel is gradually moved completely into the outer cylinder. The nose forces the polymeric resin material into the endless base structure, and air bubbles out, while forcing the endless base structure against the inner cylindrical surface.

  • Patent number: 5817265
    Abstract: An apparatus and method provide for the assembly of a multiply shaped fiber preform, the apparatus using a shaping tool having the shape of the desired part, and one or more secondary location tools, can be positioned on the shaping tool, so as to simulate a flat shape. The location tools include a number of upwardly extending location pins, such that a number of plies can be assembled in a vertical stack using the pins to assure ply to ply accuracy and orientation. After assembly, the plies are engaged in a localized portion of the assembly so as to hold the plies in register, with the secondary tools then removed and the plies then formed to shape over the tool surfaces. Utilizing the apparatus and method of the invention maintains multiple plies in register during the assembly and forming process to assure part reproducibility, in an automated process.

  • Patent number: 5798062
    Abstract: The breast appliance and method of making of the present invention is adaptive to a variety of situations ranging from a first embodiment where impressions of both breasts of a client are available for molding, a second embodiment where a single breast is available for molding, a third embodiment where a sensitive nipple or an augmentative breast appliance is to be formed, and a fourth embodiment where breast appliances are formed from a client having neither breast available for molding.If client's impression is made before surgery, a positive impression can be made directly from a negative mold. A molded silicone form or clay form is used to prepare a breast appliance front mold and a breast appliance back mold. Skin type nipple and breast skin silicone is first introduced into the mold before closure. After closure, a silicone gel is introduced into the cured skin silicone envelope, with removal of air and bubbles using an exit tube.
