  • Patent number: 6027301
    Abstract: A semiconductor wafer testing apparatus has a work table on which a carrier containing semiconductor wafers to be checked is placed. The work table is equipped for combined wafer alignment and wafer code recognition while the wafers remain in their carrier in one position on the work table. The alignment is accomplished with a wafer flat zone aligner which has a pair of roller pins each coming in contact with circumferences of the wafers being stacked in the carrier through an open lower part of the carrier and an opening in the table. The wafer code recognition is accomplished with an optical character recognizer that moves up and down and forward and backward with respect to the carrier, and interposes between the wafers in the carrier so as to read out codes which are on each wafer. This combined automated work station helps prevent contamination of the wafers by an operator or by unnecessary handling of the wafers, and also reduces cycle time for the entire inspection process.

  • Patent number: 5838245
    Abstract: A drug storage/discharge apparatus having a cleaning time determining device which can detect dirt in drug discharge paths and determine when it is necessary to clean the discharge paths. A motor control circuit controls each feeder to discharge drugs from the feeder through its discharge opening. A light-emitting diode and a phototransistor are provided opposite to each other at the discharge opening. A drug discharged from the feeder intercepts the light from the light-emitting diode, thus fluctuating the output of the phototransistor. Based on the output fluctuation, the motor control circuit can confirm that a drug has been discharged. A low-pass filter is provided to apply only a low-frequency component of the output of the phototransistor to a comparator. Such low-frequency components represent to what degree the light-emitting diode and phototransitor are soiled.

  • Patent number: 5831542
    Abstract: A seed blockage monitoring system employs a flexible, generally flat piezoelectric seed sensor element inserted at an acute angle of about 13 degrees into a seed flow path so that a portion of seeds traveling in the seed flow path strike the seed sensor element, preventing damage to the seeds and maintaining forward momentum of all seeds in the seed flow path. In order to provide flexibility in monitoring seeds of different types and to increase the data rate that information can be obtained from numerous multiple seed sensor elements, the use of a one-shot to temporarily store a seed detection signal and serial sampling of the temporarily stored signals from the sensors as in the prior art is avoided. Instead, a comparator that includes a diode in a feedback loop so as to function as a latch is used in conjunction with a serial shift register that has parallel data input lines.

  • Patent number: 5831539
    Abstract: A particle blockage monitoring system employs a flexible piezoelectric particle sensor element in a portion of a particle flow path so that a number of particles traveling in the particle flow path strike the flexible particle sensor element while preventing damage to the particles and maintaining the forward momentum of all the particles in the particle flow path. In order to provide flexibility in monitoring particles of different types and to increase the information rate, the use of a one-shot multivibrator to temporarily store a particle detection signal as in the prior art is avoided. Also, serial sampling of the particle sensor data is avoided to increase the information rate. Instead, a comparator that includes a diode in a feedback loop so as to function as a latch is used in conjunction with a serial shift register that has parallel data input lines.

  • Patent number: 5635911
    Abstract: An apparatus and method for accurately counting the number of articles passing along an article path. A light beam is transmitted across an article path to a sensor, which light beam is interfered with by the passage of articles along the article path and the received light beam is converted to electrical signals that are conditioned, amplified and input to a logic unit which, based on derived amplitude, duration and area of the input signals, determines the number of articles that passed along the article path. A system is also described which accurately counts the number of articles passing along a plurality of article paths by employing a plurality of such devices each of which accurately counts the articles passing along each article path and, upon instructions from a master console, sends its counts to the master console for summation. The system further includes a network architecture with simplified wire harnessing and enhanced operation.
