Disclosed is a Fe-based bulk amorphous alloy composition which forms a bulk amorphous substance due to its excellent amorphous formability when it is cooled to a temperature lower than its glass transition temperature from the liquid state at a relatively low cooling rate of 1000 K/s or less, has high warm processability in a low temperature range owing to its supercooled liquid region of 20K or higher and has excellent fluidity in the liquid state and thereby good castability. The Fe-based multi-element bulk amorphous alloy composition is represented by a formula of Feα, CβSiγBxPyMa, in which M is at least one element selected from Ti (titanium), Cr (chromium), Mo (molybdenum), Nb (niobium), Zr (Zirconium), Ta (tantalum), W (tungsten) and V (vanadium), α, β, γ, x, y, and a each represent atomic % of iron (Fe), Carbon (C), silicon (Si), boron (B), phosphorus (P) and the selected metal element, in which α is 100-(β+γ+x+y+a) atomic %, β is 6 atomic % or more and 13 atomic % or less, γ is 1 atomic % or more and 5 atomic % or less, x is 4.5 atomic % or more and 9.5 atomic % or less, y is 3 atomic % or more and 10 atomic % or less and a is 0.1 atomic % or more and 6 atomic % or less.

摘要:
The present invention relates to an adhesive film functionalizing color compensation and near infrared ray blocking and a plasma display panel filter employing the same. The present invention provides an adhesive film for a plasma display panel comprising an acryl-based adhesive and a near infrared ray absorbing dye. The present invention also provides an adhesive film for a plasma display panel comprising an acryl-based adhesive and a neon-cut dye. The adhesive film may further comprise a near infrared ray absorbing dye. The adhesive film of the present invention has superior durability at high temperature and humidity with little transmittance change and superior thermal stability. When further comprising a near infrared ray absorbing dye, it exerts both color compensation and near infrared ray blocking performances. Because the film has superior adhesivity in itself, an additional adhesive layer is unnecessary, which simplifies the manufacturing process of a plasma display panel filter and a plasma display panel.

Disclosed is a method for transmitting/receiving a downlink signal for improving a reception capability of a mobile station in a communication system. In the method, downlink signals are transmitted such that a downlink signal having a first Modulation and Coding Scheme (MCS) level applied thereto is first transmitted, and then the downlink signals are transmitted in a sequence in which a downlink signal having an MCS level showing a smallest difference between its MCS level and the first MCS level is transmitted prior to remaining downlink signals.

A method and apparatus is provided for transmitting/receiving a signal in a base transceiver station (BTS) of a communication system. The BTS compares power of a channel quality information (CQI) signal received from a terminal with power of a CQI signal for the terminal, received from a repeater, and performs a control operation so as to transmit a signal to be transmitted to the terminal directly to the terminal or transmit the signal to the terminal via the repeater according to the comparison result.

A transmitter and a transmitting method for forming a pseudo common beam using a plurality of antennas in a smart antenna communication system are provided, in which beams for tones of Orthogonal Frequency Division Multiplexing (OFDM) signals transmitted through a plurality of antennas are rotated at different phases around a frequency axis, such that a combined beam of the transmitted beams is equivalent to a pseudo common beam. Accordingly, a peak to average power ratio (PAPR) of the preamble signal is prevented from changing.
摘要:
A multifunctional adhesive film for a plasma display panel has an acryl-based adhesive and a near infrared ray blocking dye and a plasma display panel filter employs the same. Multifunctional adhesive film for a plasma display panel has an acryl-based adhesive, a neon-cut dye, and may further having a near infrared ray blocking dye. The multifunctional adhesive film has superior durability at high temperature and humidity with little transmittance change and superior thermal stability. When a near infrared ray blocking dye is included, it exerts both color compensation and near infrared ray blocking performances. Because the film has superior adhesivity in itself, an additional adhesive layer is unnecessary, which simplifies the manufacturing process of a plasma display panel filter and a plasma display panel.

The present invention relates to a PDP filter and a manufacturing method thereof using a fully etched electromagnetic interference film, and more particularly, to a PDP filter and a manufacturing method thereof in which the separation between an etching portion and a non-etching portion is removed by etching an entire surface of electromagnetic interference film that has been used by selectively etching a predetermined region on a surface to form an effective screen portion (etching portion) separately from a ground portion (non-etching portion), and when an electromagnetic interference film roll having such a structure is cut into a small size in a winding direction of the roller only it can be laminated with other functional films by a roll-to-roll process so as to make it applicable when required by cutting it into a desired size even though the effective size of a PDP is changed.

A data rate determining method and apparatus in a smart-antenna mobile communication system are provided. A ratio of other-cell interference to AWGN in total noise received at an MS is estimated and a power margin is applied in proportion to highly time-variant other-cell interference. Therefore, despite a change in the other cell interference between a rate decision time and an actual data transmission time, a successful data transmission rate is increased.
