  • Bullet-proof glass screen, and bullet-proof glass screen device
    Patent number: 6630235
    Abstract: A bulletproof glass screen and a bulletproof glass screen device which are relatively light and highly workable and provide a relatively high protectiveness and transparency. The rear face of a laminated glass 2, which is the opposite of the impact side of the glass, is covered by at least one sheet of plastic fracture-proof film 3.
    Type: Grant

  • Optoelectronic semiconductor devices in hermetically sealed packages
    Patent number: 4567598
    Abstract: A hermetically sealed optoelectronic semiconductor device and package assembly comprises a metallic stud providing an electrical connection to one of the device electrodes, and a heat sink mounting block for the device mounted on and electrically connected to the stud. The device is mounted on the mounting block so that the optical axis of the device is aligned with the stud axis. The mounting block has a substantially annular bottom coaxial with the stud axis so that thermal stress generated between the stud and the mounting block will be substantially balanced and deviation of the optical axis of the device will be minimized. A gap can be provided in the annular bottom to accommodate an electrical lead to which the other of the device electrodes is connected. Alternatively, the annular bottom is continuous and the electrical lead passes through the central passage provided in the stud.
