  • Patent number: 8501298
    Abstract: A resin-molded article 10 is formed by injecting molten resin into a molding die from a gate (11). Ribs (61, 62, 63 and 64) having widths larger than that of a thin molded portion (27) in the form of a thin wall are connected one after another from the position of the gate (11) to the thin molded portion (27). Spaces in the molding die for forming the ribs (61, 62, 63 and 64) define a path for the flow of the molten resin and the molten resin injected from the gate (11) flows into a space for forming the thin molded portion (27) through this path at the time of molding the resin-molded article (10). Therefore, the resin can be filled sufficiently for the thin molded portion (27) in the form of a thin wall located distant from the gate (11).

    Abstract: In a protective structure for a circuit board (1) that includes a casing (3) for receiving the circuit board, the casing is provided with a recess (11) for receiving a large component part protruding from the circuit board therein, and potting material (6) is filled in a space defined between the large component part and a surrounding wall of the recess. Typically, the potting material is filled in a gap between the large component part and the surrounding wall of the recess without substantially extending out of the recess. Because the large component part is not only supported by the circuit board but also by the casing via the cured potting material, the stress acting on a connection part that connects the large component part to the circuit board is minimized, and this enhances the mechanical integrity of the circuit board assembly.

    Abstract: A leadless ceramic chip carrier useful in surface mounting of SAW devices includes electrically conductive vias and metalization between input and output bond pads for improved crosstalk suppression between input and output device connections. A protrusion extending from a top layer of a multilayer ceramic carrier provides additional electrical contact to a package seal brazed thereto. The vias are positioned between input and output bond pads and connect the metalized protrusion to package ground pads through contact with multiple metalized layers of the package for enhancing the electrical connection between the package Kovar seal ring and customer accessed ground pads. For further suppression of crosstalk, bond pads within the package for connection to the SAW device are spaced at a greater distance from each other than their corresponding pads on the package bottom surface thus maintaining an optimum spacing for package connection to printed circuit board pads for minimizing thermal mismatch effects.

  • Patent number: 6040974
    Abstract: A capacitor cover for closing an open end of a capacitor, including an elastomeric outer layer, a rigid middle layer and a polypropylene inner layer, each with an aperture so as to allow passage of a terminal through the capacitor cover, is described. The inner layer has a peripheral skirt and an annular skirt which extend outwardly sufficiently to prevent electrolyte from the capacitor from coming into contact with the peripheral surface and the annular surface of the rigid middle layer. The capacitor cover can result in the capacitor achieving a temperature tolerance of at least about 105.degree. C. An electrolytic capacitor, including a capacitor body, an electrolyte and a capacitor cover is also described.

  • Patent number: 5998733
    Abstract: An electronic package includes a graphite-aluminum metal matrix composite (MMC) housing or support member that dissipates heat from an electronic component or circuit and a hermetic glass feedthrough seal between the graphite-aluminum MMC material and one or more electrical feedthrough pins or wires connected to the electronic component. The glass feedthrough seal comprises a low melting point, low coefficient of expansion (CTE) solder glass, such as lead zinc borosilicate, effective to form a hermetic glass-to-composite seal by a combined chemical and mechanical compression sealing force. The vitreous solder glass preferably exhibits a CTE in the range of about 41 to about 78 ppm/degree C. and a melting temperature in the range of about 300 to about 500 degrees C.

  • Patent number: 5951399
    Abstract: An ergonomic and weatherproof hand-held electronic device 10. The device 10 includes a housing 12 which surrounds internal electronics. An input 28 and a display screen 32 are mounted on the housing 12. The housing 12 is has a narrow width such that, when held in a hand, the thumb of that same hand may extend fully across the input 28 for full access. The display screen 32 is mounted vertically below the input 28 such that the device may be more stable and more easily grasped. The device includes two cylindrical cavities 48 to receive batteries 42. The cavities 48 are located at the rear vertical edges of the housing such that the rear of the housing 12 is relatively rounded and thus easier to grasp. The battery cavities open to the exterior of the housing. A battery cover 54 is mounted to the housing and seals the cavities 48. A contact for each cavity 48 is located on the cover, and a bus bar extends between the contacts to complete the circuit between the batteries 42.

  • Patent number: 5929517
    Abstract: Semiconductor chip packages and methods of fabricating the same. The package includes a thermally conductive protective structure having an indentation open to a front side and a flange surface at least partially surrounding the indentation and facing to the front of the structure. A chip is disposed in the indentation so that the front surface of the chip, with contacts thereon, faces toward the front of the structure. A flexible dielectric film having terminals thereon is placed on the flange surface, and a compliant material is disposed between the film and the flange surface. The terminals on the film are connected to the contacts on the chip. The individual terminals on the film are movable with respect to the protective structure, which facilitates mounting and compensation for thermal expansion.

    Abstract: A multielement-type piezoelectric filter capable of facilitating assembly and having a reduced size. The base substrate carries a conduction circuit. An input terminal portion, an output terminal portion and a ground terminal portion are formed on a bottom surface of the base substrate and connected to corresponding connection end portions of the conduction circuit. Furthermore, series resonators and parallel resonators are arranged side by side on the base substrate. The lower electrodes of the resonators are connected to the corresponding connection end portions of the conduction circuit via through-holes. In one embodiment, conductive sheets are attached onto exposed upper electrodes of some of the resonators so as to establish a required connection between the upper electrodes. In another embodiment, a common path layer is formed on the upper surface of the base substrate. The upper electrodes of some of the resonators are connected to the common path layer via bonding wires.
