  • Method and apparatus for transporting substrates in OLED process
    Patent number: 6658762
    Abstract: A method and an apparatus for transporting substrates in all organic light emitting diode (OLED) process is disclosed, which has a transferring chamber provided for transporting substrates between processing modules and the atmosphere condition therein is able to be adjusted to be the same as the processing module by an atmosphere conditioner unit. According to the present invention, the substrates are not contaminated by moisture and the process operation and the factory layout are more flexible. Moreover, the OLED yield is improved.

  • Cutting machine for pits on CD master
    Patent number: 4802156
    Abstract: A cutting machine for cutting pits on a laser disc master comprising a disc signal source with a RAM and a series of shift registers; a machine unit having a servo-rotary shaft for mounting a master disc; a servo-horizontally moving shaft perpendicular to the rotary shaft; a deviation sensor mounted on the horizontally moving shaft perpendicular to the master disc; and a diamond cutting tool controlled by a signal-source-controlled piezoelectric driver. It also comprises a computer unit, which includes a disc signal control interface, and machine unit control interfaces. The rotation error of the machine unit can modulate the signal output speed of the signal source.
