Abstract: According to various embodiments, a method performed in a wireless local area network (WLAN) system may comprise the steps of: receiving, by a first station (STA) supporting a first and a second link, a physical protocol data unit (PPDU) generated for a second STA, via the first link, the PPDU being received from a BSS to which the first STA belongs; setting, by the first STA, a first type NAV for the first link on the basis of the PPDU; and setting, by the first STA, a first type NAV for the second link on the basis of the PPDU.

Abstract: Provided is a method and device for transceiving a frame in a wireless Local Area Network (LAN) system. Particularly, an Access Point (AP) transmits a first frame to a first station (STA) via a first band. The AP receives a second frame from a second STA via a second band while the first frame is being transmitted. The first band and the second band are combined with each other as a multi-band. The multi-band simultaneously supports a Downlink (DL) transmission and a Uplink (UL) transmission. The relationship between the first STA and the second STA is a hidden node. A Physical (PHY) header of the first frame includes channel status information of the second band. A Network Allocation Vector (NAV) of the first STA is set up on the basis of the channel status information.

Abstract: A single-sided pressure-sensitive adhesive tape includes a substrate, a reflective metal layer disposed on a surface of the substrate, a pressure-sensitive adhesive layer disposed on the reflective metal layer, a thermoplastic polymer layer, and a light-shielding layer disposed on a surface of the thermoplastic polymer layer; wherein the light-shielding layer is dry laminated to the surface of the substrate opposite the surface on which the reflective metal layer is disposed. Articles comprising the tape, and methods of making and using the tape are disclosed.

Abstract: A foam tape having a multi-layer structure comprising a polyurethane foam core layer, at least one tie layer, adjacent one side of the polyurethane foam core layer, a first PSA film on one side of the first tie layer and a second PSA film, either on one side of a second tie layer or on one side of a polyester layer directly adjacent the opposite side of the polyurethane foam core layer, and a double-sided release layer on one side of the first PSA film. The foamed tape can be made by a process comprising applying a polymeric film to a first release layer to form a supported tie layer, referred to as Intermediate Product A, coating and drying a PSA composition on a second release layer to form a supported PSA coating, referred to as Intermediate Product B, laminating Intermediate Product B to Intermediate Product A which, after removing the release layer on the tie layer, forms Intermediate Product C comprising, in sequence, release layer, PSA film, and tie layer.

Abstract: The apparatus for thin film deposition for solar cells includes multiple unit chambers divided by a substrate as a boundary, a deposition gas injecting unit injecting deposition gases independently to each of the multiple unit chambers, and a decomposition unit in each of the multiple unit chambers to decompose the deposition gases, wherein both surfaces of the substrate each are exposed to the multiple unit chambers. The apparatus and the method for producing solar cells allow deposition on both surfaces of a substrate while the substrate is fixed without any rotation. Therefore, the number of processing units required for carrying out deposition is decreased, thereby providing high cost efficiency. Further, it results in a decrease in time during which the substrate is exposed to the exterior, thereby minimizing contamination of the surfaces of the substrate. As a result, it is possible to provide solar cells having excellent reliability.
