  • Patent number: 9559619
    Abstract: A system in which the operation of an electric motor is controlled by electronically controlled switches. The system includes the motor having a run winding and a start winding, a heating component, and a motor control subsystem. A control unit closes a first switch to energize the run winding, closes a second switch to energize the start winding, determines based on an amplitude and a lag time of a current flowing through the motor whether the motor has started and is running normally, and if so, opens the second switch to de-energize the start winding and closes a third switch to activate the heating component. The control unit determines whether the motor has started and is running normally by comparing the real time amplitude and lag time of the current to a plurality of stored amplitudes and lag times associated with different operating conditions.

  • Publication number: 20120124857
    Abstract: The present invention provides an alignment film drying device and drying method thereof for drying alignment film material, which is diluted with solvent and formed on a first surface of a substrate. The device comprises a heating stage, heating a second surface of the substrate and comprising a plurality of pores averagely distributed thereon; a peripheral supporting mechanism, being located at the periphery of the heating stage to support edges of the second surface; a plurality of support pins, being averagely distributed on an upper surface of the heating stage; and an elevator mechanism, raising and lowering the peripheral supporting mechanism and the support pins. The present invention can eliminate the phenomenon of drying alignment film unevenly in the drying process to optimize the alignment film quality for raising the display characteristic of the LCD (Liquid Crystal Display) panel and raising the quality and yield of the LCD panel.

  • Patent number: 5339537
    Abstract: A continuous drier for flat piece material, especially for liquid-coated printed circuit boards, and the like, comprises a heatable drier housing and a transport path that ascends in the housing and, after passing an upper turning point descends again. Secured to an endless chain that extends substantially vertically are carriers for the piece material to be transported, which carriers project outwards from the endless chain. The drier also comprises a supply duct for drying air for the piece material to be dried. The supply duct is so arranged that an airstream supplied by it flows over the piece material transversely to the direction in which the carriers project from the chain links.
