Abstract:
An electrically-activated photoflash lamp which includes a thin member (e.g. a mica disk) therein located between the lamp's combustible shreds and primer material. The disk prevents the shreds from contacting the primer material and any portions of the lamp's electrical conductors which have access to the interior of the envelope. A method of making the lamp is also provided.
Abstract:
A flashlamp signal device which includes an illumination means for providing a prolonged, visible signal after actuation of each of the device's flashlamps. The illumination means may be in the form of a phosphor coating within the device or on an adjacent, movable panel, or the phosphor may be impregnated within the light-transmitting housing or support structure of the device.
Abstract:
A method of making a multi-chip electronic package which utilizes an organic, laminate chip carrier and a pair of semiconductor chips positioned on an upper surface of the carrier in a stacked orientation. The organic, laminate chip carrier is comprised of a plurality of conductive planes and dielectric layers and couples one or both of the chips to underlying conductors on the bottom surface thereof. The carrier may include a high-speed portion to assure high-frequency connection between the semiconductor chips and may also include an internal capacitor and/or thermally conductive member for enhanced operational capabilities. The first chip, e.g., an ASIC chip, is solder bonded to the carrier while the second chip, e.g., a memory chip, is secured to the first chip's upper surface and coupled to the carrier using a plurality of wirebond connections.
