Circumferentially adjacent guide vanes (46, 48) define respective nozzles (44) there between. Forces created by a rotation of the turbine blade motivate ambient air through the cooling circuit. The pre-swirler is configured to impart swirl to ambient air drawn through the nozzles and to direct the swirled ambient air toward a base of the turbine blade. The end walls (50, 54) of the pre-swirler may be contoured.

    摘要: An internal voltage regulator in an integrated circuit device is always active upon initial start-up and/or power-on-reset operations. The internal voltage regulator protects the low voltage core logic circuits of the integrated circuit device from excessively high voltages that may be present in a particular application. In addition, nonvolatile memory may be part of and operational with the low voltage core logic circuits for storing device operating parameters. Therefore, the internal voltage regulator also protects the low voltage nonvolatile memory from excessive high voltages. Once the integrated circuit device has stabilized and all logic circuits therein are fully function, a bit(s) in the nonvolatile memory may be read to determine if the internal voltage regulator should remain active, e.g., how power operation with a high voltage source, or be placed into a bypass mode for low power operation when the integrated circuit device is powered by a low voltage.

    摘要: A multipurpose input/output circuit providing full input output current drive capability and special mode selection on a single device pin. The circuit includes first and second high voltage detectors coupled to the pin, at least one pin bias circuit, and a mode selector. The mode selector determines whether the pin operates as either an input or output. One of the high voltage detectors detects a high voltage on the pin and causes the bias circuit to disconnect the pin from the supply voltage. The other high voltage detector operates to detect a special mode voltage on the pin and set the device into a special mode.
