Abstract: An embodiment of the present invention relates to a cylindrical secondary battery in which a positive electrode terminal is adhered and fixed to a cylindrical can by an insulating sheet, and thus sealing between the cylindrical can and the positive electrode terminal can be facilitated due to an increased contact area.

Abstract: A cylindrical secondary battery includes: an electrode assembly including a first electrode plate and a second electrode plate; a cylindrical case having a disk-shaped top portion and a side portion extending from the top portion, the cylindrical case accommodating the electrode assembly; a cathode terminal extending through the top portion and insulated therefrom; a first current collector plate electrically connected to the first electrode plate and the cathode terminal; a second current collector plate electrically connected to the second electrode plate and the side portion of the cylindrical case; a cap plate coupled to the side portion and insulated therefrom; and an insulation tape between the top portion of the cylindrical case and the first current collector plate and covering the first current collector plate.

Abstract: Disclosed herein is a wireless repeating apparatus for mobile communication system. The present invention relates generally to a wireless repeating apparatus for repeating a signal at the same frequency as that of a wirelessly received signal in a mobile communication system. The present invention relates more particularly to a wireless repeating apparatus for mobile communication, which detects an amplitude and a phase of a wirelessly received signal and synthesizes the detected results to generate inverse phases in multiple stages, thus enabling interference signals to be eliminated, and enabling the repeating apparatus to be used over a open area using the elimination of the interference signals.
