Abstract: A method of managing intercell interference in a network and an apparatus for performing the method are disclosed. The method of managing intercell interference by a base station included in the network includes selecting a beam pattern from among a plurality of beam patterns for transmitting and receiving data between the base station and users included in the network, activating a beam corresponding to the selected beam pattern, performing a user’s scheduling on users included in the activated beam, and allocating transmission power to the activated beam to transmit and receive data to and from the users selected by the user’s scheduling.

Abstract: Disclosed herein is an apparatus and method for producing a character sculpture, wherein, when a user selects a predetermined image among 3-dimensional (3D) images with various garments or body-shapes stored in a database, it is capable of sculpturing a character sculpture corresponding to a mixed image of a user's face, adding an animation function to the mixed image, and outputting the animated image to a mobile phone, etc.

Abstract: This invention consists of two parts: "Cemented Carbide with Minimal Amount of Binder Metal", and "Nonmagnetic Cemented Carbide".The "Cemented Carbide with Minimal Amount of Binder Metal" is for cemented carbide bodies which are made from less than 2% binder metal powder and metal carbide powder. The raw powder is to be prepared following a conventional powder metallurgy method--especially the conventional method of making cemented carbide--milling, forming and sintering.The "Non-magnetic Cemented Carbide" is cemented carbides which have nickel-tungsten alloy as a binder metal. The process of manufacturing uses said conventional powder metallurgy. The purpose of this invention is to manufacture non-magnetic cemented carbide using more than two metal carbide powders and binder metal. More than one kind of metal carbides form solid solution carbide during the sintering process.

Abstract: This invention consists of two parts: "Cemented Carbide with Minimal Amount of Binder Metal", and "Nonmagnetic cemented Carbide".The "Cemented Carbide with Minimal Amount of Binder Metal" is for cemented carbide bodies which are made from less than 2% binder metal powder and more than two kinds of metal carbide powder. Neither kind of carbide powder exceeds 98% of all the carbide powder used as raw material. The raw powder is to be prepared following a conventional powder metallurgy method--especially the conventional method of making cemented carbide--milling, cold pressing and non-high-pressure sintering. During the sintering process, metal carbide powder forms complicated solid solution carbides, and the small amount of binder which initially helped sintering is lost for the most part, if not entirely, during sintering.The "Non-magnetic Cemented Carbide" is cemented carbides which have nickel-tungsten alloy as a binder metal. The process of manufacturing uses said conventional powder metallurgy.
