Abstract: Disclosed is a blowing unit of an air conditioner for a vehicle, having a two-layer structure and capable of effectively suppressing a flow of air flowing backward around a scroll bell mouth. In a blowing unit of an air conditioner for a vehicle, having a scroll case in which a first flow path and a second flow path are partitioned so as to separate inside and outdoor air to be sucked, the scroll case has a partition wall for separating a suction part of the first flow path and a suction part of the second flow path, and the partition wall has an air backflow prevention part for preventing air flowing into one of the first flow path or the second flow path from flowing backward into the other.

Abstract: An apparatus and method for cleaning an oxide film using a direct current reverse polarity are provided. The apparatus for cleaning an oxide film formed on a workpiece may include a power supply configured to apply direct current power and to include a positive electrode terminal and a negative electrode terminal, the workpiece configured to be electrically connected to the negative electrode terminal to act as a negative electrode to which a current is applied, and a torch having a positive electrode, which is spaced apart from the oxide film by a predetermined distance and is electrically connected to the positive electrode terminal, the torch being installed to be movable relative to the workpiece. The oxide film formed on the workpiece may be removed by applying a reverse polarity direct current between the workpiece, serving as the negative electrode, and the positive electrode to generate an arc.

Abstract: A method of detecting an illegal broadband radio signal, includes receiving, by a reception unit, a surrounding radio signal at a place where an illegal radio signal is to be detected, generating, by a detection unit, reference frequency information by configuring a reference multi-spectrum table, generating, by the detection unit, detection frequency information by configuring a detection multi-spectrum table in such a way as to generate a basic resolution spectrum by extracting the signal of the preset frequency band as basic resolution from a detection radio signal detected in the place, and identifying, by a determination unit, whether a signal intensity value greater than a signal intensity value of the reference multi-spectrum table is present in the detection multi-spectrum table.

Abstract: The present invention relates to a 2-layer printed circuit board (PCB) for enabling impedance matching of a high frequency signal line, and a method of manufacturing the 2-layer PCB. In the present invention, an insulation layer with a predetermined thickness is formed as an insulation substance on a top surface of a signal layer formed on a general 2-layer PCB so as to protect a high frequency signal line formed on the signal layer. An auxiliary layer selectively including carbon, a PCB, a tape in the form of copper foil or the like is formed on a top surface of the insulation layer. At this time, the thickness of the insulation layer is determined to be different depending on a material of the auxiliary layer. Further, the auxiliary layer and a ground layer provided to the 2-layer PCB are electrically connected to each other. Then, the auxiliary layer serves as a ground plane.
