  • Carriage drive belt with compliant belt section for inkjet printer
    Patent number: 6508534
    Abstract: A carriage drive belt for an inkjet printer includes an elongated belt section and compliant belt section secured to the elongated belt section. The elongated belt section has a longitudinal axis and includes a first portion and a second portion spaced from the first portion along the longitudinal axis. The compliant belt section extends between the first portion and the second portion of the elongated belt section and has an axis extending in a direction of the longitudinal axis of the elongated belt section.

  • Printing mechanism having a direct current motor with imbalanced winding for closed-loop feedback control
    Patent number: 6150777
    Abstract: A direct current motor for use in a closed-loop control system is disclosed that includes a rotating commutator having a plurality of slots, a plurality of windings, the number of windings that conduct current corresponding to one less than the number of slots of the commutator, and a plurality of brushes that are configured so that application of a direct current voltage across the brushes results in a current flow in at least one of the windings which causes the commutator to rotate. Continuous application of the direct current voltage across the brushes causes the current to flow in a varying number of the current conducting windings as the commutator continues to rotate, the number periodically varying from all of the current conducting windings to the at least one current conducting winding.

  • Direct current motor for closed-loop feedback control
    Patent number: 5955853
    Abstract: A direct current motor for use in a closed-loop control system is disclosed that produces a time varying signal indicative of a position of the motor. An embodiment of the motor includes a rotating commutator having a plurality of slots, a plurality of windings, the number of windings corresponding to one more than the number of slots of the commutator, and a plurality of brushes that are configured so that application of a direct current voltage across the brushes causes the commutator to rotate.A closed-loop control system is also disclosed that includes a direct current voltage source, a direct current motor in accordance with the present, a motor position signal source that generates a motor position signal for rotating the shaft of the direct current motor to a desired position, and a feedback circuit that corrects for any error in the desired position of the shaft of the direct current motor.
