    摘要： A method of fabricating a component is provided. The method includes forming one or more grooves in a surface of a substrate, where the substrate has at least one hollow interior space. Each of the one or more grooves extends at least partially along the substrate surface and has a base and a top. The base is wider than the top, such that each of the one or more grooves comprises a re-entrant shaped groove. The method further includes forming one or more access holes through the base of a respective groove, to connect the groove in fluid communication with respective ones of the hollow interior space(s), and disposing a coating over at least a portion of the substrate surface. The one or more grooves and coating define one or more re-entrant shaped channels for cooling the component. A component with one or more re-entrant shaped channels and a method of coating a component are also provided.

    摘要： A method for monitoring machining in an electroerosion assembly having a power supply and an electrode arranged across a gap from a workpiece, includes measuring a voltage at a point in a voltage waveform after a time delay td of one half of a pulse width of the voltage waveform. The measurements are repeated for multiple pulses of the voltage waveform to obtain multiple voltages, each of the voltages corresponding to a point in respective pulses. The voltages are averaged to obtain an average voltage, which is compared with at least one threshold voltage, to determine whether the machining is in control. A control signal is generated if the comparison indicates that the process is not in control, the control signal being configured to regulate an operating parameter of the power supply, and the control signal is supplied to the power supply, if generated.

    摘要： A differential offset circuit adapted for an adaptive filter of a receiver front end is provided. The differential offset circuit includes four controllable current sources which are respectively coupled to two differential output terminals of the adaptive filter. The current magnitudes of the controllable current sources are capable of being adjusted according to design requirements so that the differential offset of the adaptive filter is mitigated to avoid that the adaptive filter outputs a distorted signal to affect the accuracy of signal transmission.
