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: A TV control system includes: a TV control device which generates a viewing distance detection value and an illumination level detection value, inputs a setting value transmitted from the smart phone, and transmits a human body distance detection value, the illumination level detection value, the setting value, and a control signal to the smart TV; the smart TV which receives the viewing distance detection value, the illumination level detection value, and the setting value transmitted from the TV control device, and changes a distance and time setting value in response to the control signal; the smart phone which generates a control signal for changing distance information and a control signal for changing time setting and transmits the control signals to the TV control device; and a router which is connected to the smart phone and the TV control device through a communication network.

Abstract: An apparatus for manufacturing solder balls including a tundish, a vibrator, a cooling liquid tank an inactive atmospheric chamber, a molten metal receiving tray, a ball collecting barrel, and a cooling liquid reservoir. The tundish has orifices at its bottom. The vibrator is immersed in the molten metal of the tundish and generates vibrations. The cooling liquid tank is situated under the tundish and is provided with a cooling liquid heater at its upper and middle outer surface, a cooling liquid cooler at its lower outer surface, and a cooling liquid discharge conduit at its top. The inactive atmospheric chamber is interposed between the bottom of the tundish and the op surface of the cooling liquid. The molten metal receiving tray is seated on a portion of the inactive atmospheric chamber and is horizontally movable.
