    摘要: A method for forming CNT multilayer film patterns, which comprises repeatedly attaching CNTs having exposed carboxyl groups onto a substrate having exposed amine groups by amide linkage, so as to form a CNT multilayer film, and then forming CNT multilayer film patterns from the CNT multilayer film by photolithography and dry etching. Also disclosed is a method for fabricating CNT multilayer film patterns where a variety of chemical functional groups are exposed, by thermally treating CNT multilayer film patterns obtained as provided in the preceding sentence, to obtain CNT multilayer film patterns devoid of surface defect sites, followed by physically attaching either surfactants or chemical substances having sites capable of π-stacking, to the CNT multilayer film patterns devoid of defect sites. Such methodology allows fabrication of clear CNT multilayer film patterns in which CNTs are attached only at selected regions, resolving prior art issues of CNTs being attached also at non-selected regions. CNT multilayer film patterns having chemical functional groups physically attached thereto and exposed to the surface, are useful in the fabrication of biosensors.

    摘要: Provided are a transcoding apparatus and method. A frame comparator compares the length of input frames of a transmitting side with the length of output frames of a receiving side. A frame deciding unit decides more than one input frame corresponding to one output frame on the basis of the comparison result and decides the type of the output frame based on the type of the corresponding input frame. A frame converter converts the format of the input frames to the format of the output frames on the basis of the decided type. Accordingly, a frame coded by a voice coder using VAD is easily transformed to the format of another voice coder.
