  • Method and apparatus for mounting electronic component
    Patent number: 6044169
    Abstract: In a method and an apparatus for mounting of electronic components onto a board, there are provided a head section (35) having a plurality of nozzles (12, 13) for sucking electronic components and a recognition camera (15) for recognizing a posture of a sucked electronic component through its image. A controller (1) is provided for controlling the head section so that after the electronic components at a component feed section (30) are sucked by the nozzles, the sucked posture is image-recognized by the recognition camera and corrected.

  • Gas discharge display apparatus
    Patent number: 4734686
    Abstract: A gas discharge display apparatus consisting of a gas discharge display panel and a drive circuit for driving a matrix array of display elements formed in the display panel by mutually perpendicular arrays of stripe-shaped anodes and cathodes, the cathodes being sequentially selected during successive scanning intervals and the anodes driven to produce a light-emitting or non-emitting state during each scanning interval in accordance with display data. During each scanning interval, each anode for which the non-emitting state is to be maintained is momentarily driven to the light-emitting state potential during a brief interval, to thereby substantially increase the reliability of display operation during the immediately succeeding scanning interval.
