Abstract: A heat exchanger and an integral sealing device (100, 200, 300, 400, 500) used for a manifold (10, 10?) in the heat exchanger. The manifold (10, 10?) on one side of the heat exchanger comprises two pipelines (11, 12, 11?, 12?) which are parallel to each other and communicated with each other. A first bore (13) and a second bore (14) are formed in two pipelines (11, 12, 11?, 12?) due to a drilling process. The first bore (13) is used for enabling refrigerant to flow from a cavity of one of two pipelines (11, 12, 11?, 12?) into a cavity of the other pipeline. The second bore (14) is a process hole left by the drilling process, and the integral sealing device (100, 200, 300, 400, 500) seals the process hole.

Abstract: Methods and systems for filtering scratches from wafer inspection results are provided. One method includes generating a defect candidate map that includes image data for potential defect candidates as a function of position on the wafer and removing noise from the defect candidate map to generate a filtered defect candidate map. The method also includes determining one or more characteristics of the potential defect candidates based on portions of the filtered defect candidate map corresponding to the potential defect candidates. In addition, the method includes determining if each of the potential defect candidates are scratches based on the one or more characteristics determined for each of the potential defect candidates and separating the potential defect candidates determined to be the scratches from other defects in inspection results for the wafer.

Abstract: A multi-path simulation system (100) includes a signal generator (10) generating a signal, a power divider (24) connected to the signal generator for dividing the signal into N attenuated sub-signals, N delay lines (26) connected to the power divider delaying the N attenuated sub-signals to simulate the delays resulting from the transmission of the signal in the N paths, P switches (28) connected to the delay lines selecting the attenuated sub-signals delayed by the delay lines, thereby generating selected signals, and a signal combiner (29) connected to the switches combining the selected signals into a single signal. The delay lines are respectively represented by transmission lines disposed on a printed circuit board. A length of the transmission line controls a distance of transmission of the signal. Wherein N is an integer greater than one, and P is an integer equal to or greater than one.
