Abstract:
The present invention provides an apparatus for removing particles using symmetrical gas injection, the apparatus comprising: a casing having an inner space; a gas injection part in which a plurality of gas nozzles are formed on one side of the casing, the plurality of gas nozzles are disposed symmetrically and away from an object, and particles on the surface of the object are removed by means of injecting gas on the object; and a recovery part which has a recovery pipe inserted therein and connected to the other side of the casing and is for recovering, via the recovery pipe, the particles which have been removed from the object. According to the present invention, the gas nozzles inject in symmetrical directions and thus diffusion of particles removed from the surface of the object is prevented, the object is not contaminated, and the particles can accurately be recovered, detected and counted.

Abstract:
A link quality reporting method and apparatus, and a carrier selection method and apparatus, for a multicarrier communication system utilizing carrier aggregation are disclosed. In the system, the user equipment measures, for each component carrier divided into a Physical Downlink Shared Channel (PDSCH) resource region and a Physical Downlink Control Channel (PDCCH) resource region, link quality of the PDSCH resource region and the PDCCH resource region of the component carrier and sends measured link quality information as feedback information to the base station, and the base station adaptively selects a set of component carriers for control information transmission (i.e., a PDCCH Component Carrier (CC) SET) and a set of component carriers for data transmission (i.e., a DownLink (DL) CC SET) on the basis of the feedback information.
Abstract:
Disclosed herein is a carrier for manufacturing a substrate, including: a base plate; adhesive layers formed on one side or both sides of the base plate; auxiliary adhesive layers, each of which is buried in one side of each of the adhesive layers, has a smaller area than each of the adhesive layers and has lower adhesivity than each of the adhesive layers; and metal layers, each of which is formed on one side of each of the auxiliary adhesive layers, whose edges are attached to the adhesive layers, and whose other portions excluding the edges are attached to the auxiliary adhesive layers. The carrier is advantageous in that a metal layer and an auxiliary adhesive layer are attached to each other by the adhesivity of the auxiliary adhesive layer, so that it is not required to use vacuum adsorption, with the result that a process of manufacturing a substrate can be performed more stably.

Abstract:
A method for calibrating a camera including (a) obtaining a two-dimensional (2D) homography that maps each of parallelograms projected onto images taken by two arbitrary cameras into a rectangle, wherein the 2D homography is defined as a rectification homography and wherein new cameras that have virtual images are defined as rectified cameras and a new infinite homography is generated between the two rectified cameras, the virtual images being transformed from original images by the rectification homography; (b) obtaining an original infinite homography by using the correlations among the new infinite homography, the rectification homography and the original infinite homography; and (c) obtaining intrinsic camera parameters based on the correlation between the original infinite homography and the intrinsic camera parameters, thereby calibrating the camera.
Abstract:
Provided is an apparatus for tightening wire, comprising: a housing (10); a spool (20) mounted to the housing to wind a wire; a winder (30) that engages with the spool to wind the wire or disengages from the same to unwind the wire; a ratchet (40) that allows axial rotation in one direction in which the wire is tightened; a spiral cam (50) where the winder and the ratchet are mounted; and a dial (60) mounted to the spiral cam to axially rotate the winder. The apparatus provides an engagement and disengagement structure that allows the spool and the winder to engage or disengage, so that, by forward and backward rotations, only the wire is wound when the spool and the winder engage and the wire is unwound when the spool and the winder disengage, thereby allowing the winding and unwinding of the wire by simple forward and backward rotating operation.
