An apparatus and a method for receiving a multiple frequency band are provided. In the method for receiving a multiple frequency band of a terminal is a mobile communication system, respective received signal strengths or respective gains are measured with respect to a signal received via at least one Radio Frequency (RF) chain. Whether multiple frequency band reception that uses a single RF chain is possible is determined using the respective received signal strengths or the respective gains. When the multiple frequency band reception that uses the single RF chain is possible, the multiple frequency band is received using the single RF chain.

A carbon substrate, method, and a system for manufacturing the same. The method includes forming an oxidized carbon precursor fiber preweb comprising oxidized carbon precursor staple fibers and binder staple fibers; impregnating the oxidized carbon precursor fiber preweb with a slurry including a thermosetting resin and carbonaceous fillers and drying the resulting preweb to obtain an oxidized carbon precursor fiber web; applying heat and pressure to the oxidized and impregnated carbon precursor fiber web, to cure the thermosetting resin and press the oxidized carbon precursor fiber web; and heating the oxidized carbon precursor fiber web in an inert atmosphere, thereby stabilizing and carbonizing the oxidized carbon precursor staple fibers to obtain a carbon substrate. The present invention may utilize a combination of carbon precursor staple fibers in an oxidized form with low ductility and high stiffness; and binder staple fibers composed of a polymer resin.

A method and apparatus for forming magnetic media substrates is provided. A patterned resist layer is formed on a substrate having a magnetically susceptible layer. A conformal protective layer is formed over the patterned resist layer to prevent degradation of the pattern during subsequent processing. The substrate is subjected to an energy treatment wherein energetic species penetrate portions of the patterned resist and conformal protective layer according to the pattern formed in the patterned resist, impacting the magnetically susceptible layer and modifying a magnetic property thereof. The patterned resist and conformal protective layers are then removed, leaving a magnetic substrate having a pattern of magnetic properties with a topography that is substantially unchanged.

A repeater, a remote management system of a repeater and a method arc provided for variably attenuating an input signal. A repeater relays at least one frequency band signal between a base station and a service side, includes at least one variable attenuator for variably attenuating each of at least one frequency band signal, variably attenuates an input signal that is received from the base station through the variable attenuator, and transfers the input signal to the service side. Further, a remote management system of the repeater communicates through the repeater and a mobile communication network and includes a repeater management server for requesting to change an attenuation value of the variable attenuator to the repeater when the input signal is an excess input signal.

A semiconductor device includes a storage node contact plug, a bit line in communication with to the storage node contact plug, and an expansion unit formed on a sidewall of the bit line. Thermal expansion of the expansion unit serves to increase capacitance by ensuring a distance between the bit line and the storage node contact plug, thereby improving a sensing margin. A cell characteristic such as a record recovery time (tWR) may be enhanced.
