  • Loudspeaker moment and torque balancing
    Patent number: 8295537
    Abstract: A loudspeaker including a moving magnet motor. The moving magnet motor includes an armature comprising a magnet carrier, and a lever arm, coupling the armature and a pivot. The lever arm further couples the armature and an acoustic diaphragm to transmit motion of the armature to the acoustic diaphragm to cause the acoustic diaphragm to move. The loudspeaker described may be torque balance and moment balanced.
    Type: Grant

  • Substrate holder having vacuum holding and gravity holding
    Patent number: 6123502
    Abstract: A substrate processing apparatus having a substrate transport with substrate holders. The holders are adapted to vacuum hold substrates and thereby allow for rapid movement of the substrates without risk that the substrates will move off of the holders. If vacuum holding of a substrate on a holder fails, the movement of the substrate holder is automatically changed to provide a less rapid gravity only holding of the substrate on the holder.
