Abstract: A positive electrode material for a lithium secondary battery has improved electron conductivity and surface stability because oxidation-treated carbon nanotubes are stably attached to the surface of an active material. According to one embodiment the positive electrode material includes a positive electrode active material core made of a Li—Ni—Co—Mn-M-O-based material (M=transition metal) and an oxidized carbon nanotube coating layer formed on the surface of the positive electrode active material core and including 1% to 3% by weight of oxidation-treated carbon nanotubes (OCNT) relative to 100% by weight of the positive electrode active material core.

Abstract: A positive electrode material for a lithium secondary battery and a manufacturing method therefor are provided. The positive electrode material may have carbon nanotubes stably attached to a surface of an active material and may exhibit increased electron conductivity and improved surface stability. The positive electrode material for a lithium secondary battery may comprises: a positive electrode active material core comprising a Li—Ni—Co—Mn-M-O-based material, where M is a transition metal; and a carbon nanotube coating layer on a surface of the positive electrode active material core. Carbon nanotubes (CNT) may be in an amount of 1-5 wt %, based on 100 wt % of the positive electrode active material core.

Abstract: An image forming apparatus is provided. The apparatus includes a body, a case forming an external appearance of the body, and a card reader disposed at an inside the case. The case includes a supporting member protruding from an inner surface of the case to support a lower end of the card reader, and a pressing member configured to press the card reader toward the inner surface of the case, so that various types of card readers having a different width, height, and/or thickness may be installed for use.

Abstract: An image forming apparatus may includes an image carrying body, a intermediate transferring unit which includes an intermediate transferring belt to which a visible image on the image carrying body is transferred, a driving roller to drive the intermediate transferring belt, and a first roller support unit to support a rotation shaft of the driving roller. The image-forming apparatus also includes a medium transferring unit to transfer a visible image on the intermediate transferring belt to a printing medium and includes a transferring roller to move between a pressing position pressing the driving roller to interpose the intermediate transferring belt therebetween and a separated position separated from the pressing position, and a second roller support unit to support a rotation shaft of the transferring roller. The pressing position of the transferring roller can be regulated by a contact of the first roller support unit and the second roller support unit.

Abstract: Provided is a locking mechanism for a flat display device. The locking unit for a single axis rotation flat display device in which an upper body and a lower body are coupled to each other by a rear main hinge, includes: a latch member movable on a guide disposed in the upper body, a locking hole formed in the latch member and a bent portion slantingly bent at a lower end of the latch member which is made of a ferromagnetic material. In a retracted state, the latch member is substantially disposed within the upper body, while in deployed state the latch member protrudes therefrom. A restoration member provides a restoration force to the latch member so as to urge it into its retracted state. A hook member hingedly coupled to the lower body. The hook member having a hook portion whose upper end engages the locking hole. a magnet is installed to or in proximity to the hook member under the hook portion.
