  • Publication number: 20200064276
    Abstract: Systems and methods related to a structured illumination (SI)-based inspection apparatus are described. The SI-based inspection apparatus may be capable of accurately inspecting an inspection object in real time with high resolution, while reducing the loss of light. Also described are an inspection method, and a semiconductor device fabrication method including the SI-based inspection method. The inspection apparatus may include a light source configured to generate and output a light beam, a phase shifting grating (PSG) configured to convert the light beam from the light source into the SI, a beam splitter configured to cause the SI to be incident on an inspection object and output a reflected beam from the inspection object, a stage capable of moving the inspection object and on which the inspection object is arranged, and a time-delayed integration (TDI) camera configured to capture images of the inspection object by detecting the reflected beam.

  • Patent number: 10087809
    Abstract: A system and method for preventing a failure of an exhaust heat recovery device are provided. The method includes operating a sole exhaust heat recovery mode when cooling water has a temperature less than a warm-up reference temperature to introduce all exhaust gas flowing from a DPF into the exhaust heat recovery device where the exhaust gas exchanges heat with the cooling water. Additionally, a passage through which the exhaust gas bypasses the exhaust heat recovery device is opened when the exhaust gas at a rear of the DPF has a temperature greater than the warm-up reference temperature during the sole exhaust heat recovery mode.

  • Patent number: 6574122
    Abstract: A low-noise, high-power-factor power supply includes a transformer having a primary winding connected to a pair of a.c. input terminals via a rectifier circuit, and a secondary winding connected to a pair of d.c. output terminals via a rectifying and smoothing circuit. Connected between the pair of outputs of the rectifier circuit via at least part of the transformer primary, a switch is turned on and off to keep the d.c. output voltage constant. A smoothing capacitor is connected between the pair of outputs of the rectifier circuit via at least part of the transformer primary and a serial connection of a reverse blocking diode and an inductor. For noise reduction a bypass capacitor is connected between the pair of outputs of the rectifier circuit and in parallel with the serial circuit of the inductor and the reverse blocking diode and at least part of the transformer primary and the smoothing capacitor. The bypass capacitor is less in capacitance than the smoothing capacitor.
