  • Manufacturing method and apparatus for adjusting the position of a magnetic head in a flexible disk drive
    Patent number: 4458274
    Abstract: During manufacture of a flexible disk drive, the drive's head is located in its penetration, radial, azimuth, tangential, roll and pitch attitudes by reading a test disk, as the head is held by a robotic head holder/manipulator. The head's signal produces closed-loop control of a serially-stacked array of rotary and linear motors which position the holder/manipulator. After the head is properly adjusted, it is clamped to the disk drive's head carriage.
    Type: Grant

  • Laser joining of thermoplastic and thermosetting materials
    Patent number: 4414166
    Abstract: Thermoplastic materials are joined to non-thermoplastic materials such as thermosetting materials by laser radiant energy which causes the thermoplastic material to flow onto the thermosetting material, preferably into a notch or groove or over a shoulder or lip to form a joint by mechanically locking the materials together.
