  • Patent number: 7514825
    Abstract: A cooling apparatus is provided for a linear motor that comprises a coil assembly and a magnet assembly, wherein the coil assembly generates heat during operation. The cooling apparatus comprises a compressed air inlet positioned to discharge compressed air in a direction directly towards a gap between the coil assembly and magnet assembly, and an inclined surface extending from the compressed air inlet and sloping at an obtuse angle away from the discharge direction of the compressed air. The compressed air inlet is configured to discharge the compressed air at a sufficient velocity so as to entrain atmospheric air along the inclined surface to amplify the compressed air that is discharged.

  • Publication number: 20090056761
    Abstract: A bonding apparatus for bonding materials onto a substrate supported on a substrate support is provided with an air generator that is arranged and configured to direct an air flow onto the substrate during bonding. The air generator is located on one side of the substrate support, whereas a suction device is located on an opposite side of the substrate support which is operative to draw the air flow away from the bonding apparatus. The air generator further comprises an air knife that is operative to generate a unidirectional air flow over an entire length of the substrate during bonding.
