Abstract: Proposed is an apparatus for measuring sealing strength. The apparatus includes a fixed plate, a moving plate on which a measurement object formed by bonding first and second specimens is mounted, and movably disposed on the fixed plate, and a load applier measuring a load applied to the first specimen to peel off the first specimen from the second specimen. The first specimen is peeled off from the second specimen while maintaining a predetermined peeling angle.

Abstract: An apparatus for manufacturing a pouch-type rechargeable battery includes a preforming portion forming a folding groove in a portion of a protrusion of the pouch-type rechargeable battery, a folding portion disposed on a rear end of the preforming portion and folding the protrusion along the folding groove, a rolling portion disposed on a rear end of the folding portion and pressing the folded protrusion, and a pressing portion disposed on a rear end of the rolling portion and fixing the folded protrusion.

Abstract: A coil component is provided. The coil component includes a body having fifth and sixth surfaces opposing each other, first and second surfaces respectively connecting the fifth and sixth surfaces of the body and opposing each other, and third and fourth surfaces respectively connecting the first and second surfaces of the body and opposing each other in one direction, a recess disposed in an edge between one of the first and second surfaces of the body and the sixth surface of the body, a coil portion disposed inside the body and exposed through the recess, and an external electrode including a connection portion disposed in the recess and connected to the coil portion, and a pad portion disposed on one surface of the body. A length of the pad portion in the one direction is greater than a length of the connection portion in the one direction.

Abstract: A DC powered electric heating pad for a bed is invented comprising a plurality of carbon fiber filaments (2a) arranged in parallel for generating heat, a power distributing element (2c) for supplying power to the carbon fiber filaments (2a), a pair of metal bands (2b) for coupling both ends of the carbon fiber filaments (2a) and distributing the power supplied through the power distributing element (2c), a thermal material (2) for enveloping the carbon fiber filaments (2a) to consistently maintain the heat, and covering materials (1, 3) for protecting the thermal material (2) and the carbon fiber filaments (2a). An adapter with a bridge rectifier circuit is plugged into a regular outlet of AC as a power source for transforming to DC. The carbon fiber filament (2a) emitting the far-infrared with negative ions is designed to have excellent conductivity, durability, and ultra-light weight for protecting against harmful electrical waves by using DC.
