  • Method and apparatus for detecting bent leads in electronic components
    Patent number: 5490084
    Abstract: Electronic components such as integrated circuit components have rows of parallel leads extending from the sides of their bodies. In detecting bent leads of an electronic component, at least two measuring lines are set along each row of leads. The intersections between the measuring lines and the leads are extracted and processed to detect a bend in leads. The electronic component is photographed to produce image data which is stored in a memory. At least two measuring lines are virtually set along the row of leads of the image data stored in the memory. An intersection extractor extracts, from the image data, the intersections between the measuring lines and predetermined leads in the row of leads. A detector then uses the extracted intersections to detect bent leads.

  • Information processing and storage system with signal transmission loop line
    Patent number: 5010479
    Abstract: An information processing system includes a loop-shaped signal transmission line for transmitting data to be stored, a plurality of transmission control processors disposed around the transmission line, and information processing units for inputting and outputting data to and from the signal transmission line through the corresponding transmission control processors. Each of the transmission control processors is adapted to variably control the signal amplitude of data flowing around the signal transmission line in accordance with the utilization of the data in the corresponding information processing unit.
