Abstract: An anode for a lithium secondary battery includes an anode current collector, a second anode active material layer disposed on the anode current collector and including a second anode active material that includes a graphite-based active material and composite particles, and a first anode active material layer disposed between the anode current collector and the second anode active material layer and including a first anode active material that includes a graphite-based active material and does not include the composite particles. Each of the composite particles includes a carbon-based particle including pores, a silicon-containing coating layer disposed on an inside of the pores of the carbon-based particle or on a surface of the carbon-based particle, and a surface oxide layer disposed on the silicon-containing coating layer and including a silicon oxide.

Abstract: Disclosed is a portable communication apparatus. The portable communication apparatus includes a first housing including a plurality of keys, a second housing including a main display unit and being movable from the first housing about a first hinge axis and being rotated about a second hinge axis, which is perpendicular to the first hinge axis, and a swing hinge housing for allowing the second housing to rotate with respect to the first housing about the first and second hinge axes, which pass through the swing hinge housing. The swing hinge housing is provided at a lateral portion thereof with a camera lens. A bottom surface of the swing hinge housing is rotatably attached to an upper surface of the first housing so that the swing hinge housing is rotated together with the main display unit about the second hinge axis.

Abstract: A folding-type wireless handset has the usability of a folding-type portable apparatus and functions as an auxiliary portable apparatus of a portable apparatus having large horizontal and vertical dimensions, such as a PDA, using a short-distance communication means. The handset includes a handset body having a number of keys and a short-distance communication means; a handset folder having a display device; and a hinge device for rotatably connecting the handset body and the handset folder to each other. Dialing can be performed using the keys and bidirectional communication with a desired partner can be performed by transmitting and receiving signals between the body of a portable apparatus and the handset body using the short-distance communication means.
