Abstract: Disclosed is a waveguide adapter able to generate a circularly polarized wave. The waveguide adapter to be coupled with a horn antenna realizes a polarized wave conversion function for converting a linearly polarized wave signal into a circularly polarized wave signal, or vice versa, and an adapter function for converting a waveguide signal into an external transmission line signal, resulting in a simplified configuration and small size of a communication system using a circularly polarized wave signal. The waveguide adaptor includes a probe to transmit a linearly polarized wave signal from an external transmission line to a waveguide transmission line, a polarized wave conversion line reflector located in the rear of the probe to convert a vertically polarized wave into a horizontally polarized wave, and a back-short member to forwardly transmit a rearward signal. The waveguide adapter is applicable to communication systems using circularly polarized wave signals.

Abstract: A non-volatile memory device including a barrier spacer that serves to protect a control gate, including a metal layer, from damage that may result from exposure to a cleaning solution and/or oxygen. With the barrier spacer layer, a cleaning process using a high-power cleaning solution may be used to effectively remove etch byproducts. An oxidation process may be performed to cure etch damage of an intergate dielectric pattern, a floating gate and a gate insulator. The barrier spacer and/or the oxidation process enable a non-volatile memory device having enhanced speed and reliability to be formed.

Abstract: Provided are a method for generating a two-dimensional orthogonal variable spreading code and a Multiple Input Multiple Output (MIMO) system using the same. The MIMO system can increase a communication capacity in an asynchronous multiple user system as well as a synchronous system in a wideband-Code Division Multiple Access (CDMA). The MIMO system includes: a transmitting block for temporally and spatially encoding a plurality of user data, spreading the user data into orthogonal channel signals, and transmitting them to antennas; and a receiving block for receiving the orthogonal channel signals and performing temporal and spatial decoding and despreading on them. Herein, the transmitting block includes: a space time code (STC) encoding unit for generating and outputting a predetermined number of STC streams; and a jacket orthogonal variable spreading function (JOVSF) channel code spreading unit for spreading the STC streams into orthogonal channel signals by using a JOVSF.

Abstract: A rendering system and method, and a recording medium therefor are provided. The rendering system imports geometry and hierarchy structure information on a three-dimensional (3D) computer-aided design (CAD) model, which is produced in a commercial 3D CAD system, from the 3D CAD system through an interface, performs scene editing necessary for rendering without changing the initially modeled data, and then performs rendering. Accordingly, it is not necessary to correct the geometry data and restore the hierarchy structure information, and rendering can be easily performed in a short time.

Abstract: A muller for finely mulling a material to be processed is disclosed. The muller comprises a nozzle unit (10) including feed lines (12a and 12b) and hollow pipe lines (120a and 120b), a mulling unit (20) including a mulling head (22), and an input device (30) including a hopper (310) and a feeder (322). The muller finely mulls the material even if it has a relatively large particle size, and continuously feeds the material while mulling it in order to improve productivity. The muller conducts cold mulling of the material or maintains the temperature thereof by employing a cooling system to prevent the generation of heat due to inter-material collision as the material is transferred, or friction against the feed lines, thereby extending the lifespan of the muller. The muller requires no separate classifier by employing successively arranged mulling units (20a to 20n) to accomplish a high economical efficiency.
