The present invention relates to polypeptides that inhibit the NF-&kgr;B signaling pathway and polynucleotides encoding the same. The receipt interface IF receives pages of image data transmitted and a partial print request signal requesting that only a part of the image data be printed, both transmitted through a communication line. A substance is delivered to the chamber to assist the prosthesis placement. A combing part combines the received signals in such a manner that align the rear end of each repetitively transmitted data portion except the leading data portion with the rear end of the leading data portion extracted by the leading data extracting part. The product stream typically contains less than 20 ppm total alkynes. The invention is particularly applicable to flat field emission displays.
