Abstract: A method includes the following steps: a first step: the material containing heteroatom and graphite powder are mixed for a preset time by grinding, and the molar ratio of heteroatom to carbon atom is 1%-10%, then the heteroatom precursors are obtained; a second contact step: the heteroatom precursor is filled into a graphite rod with holes and compacted, then the graphite rod is dried for a preset time to obtain a plasma anode and using a DC arc plasma device to prepare the graphite anode into heteroatom-doped CNHs; a third contact step: the heteroatom-doped CNHs are dispersed in a reducing solution, a platinum salt is added to stir evenly, the reduction reaction is carried out by heating and stirring, and after centrifugation, washing and drying, a catalyst with platinum loading is obtained.

Abstract: An object inspection system and a method for detecting defects which utilizes a plurality of cameras and lights to capture images of a portion of an object and which uses the captured images to determine the presence of a defect upon a surface, such as surface, of the object and which may communicated the location of the identified defect to an automated defect repair assembly.

Abstract: The present disclosure provides a method for controlling a 3D NAND memory using a read operation. The method can include increasing a voltage to a plurality of top select gates, with respect to a first reference voltage level, during a pre-pulse period of the read operation prior to a read period of the read operation. The method can also include increasing a voltage to a plurality of word lines, with respect to a second reference voltage level, during the pre-pulse period. The method can also include decreasing a voltage to a bit line, with respect to the first voltage, during the pre-pulse period. The method can also include applying no voltage change to a bottom select gate during the pre-pulse period.

Abstract: A time-to-digital converter is provided. The time-to-digital converter comprises an oscillator controller, an invertible oscillator and a measurement circuit. The oscillator controller receives a start signal and a stop signal and outputs a mode signal. The invertible oscillator is electrically connected with the oscillator controller for receiving the mode signal. The oscillation direction of the invertible oscillator is inverted according to the mode signal, and the invertible oscillator outputs plural delay signals. The measurement circuit is electrically connected with the invertible oscillator for receiving the plural delay signals. The measurement circuit receives a sampling signal, samples the plural delay signals in accordance with the sampling signal, and outputs an output signal.
