| 20090249059 | PACKET ENCRYPTION METHOD, PACKET DECRYPTION METHOD AND DECRYPTION DEVICE - A packet encryption method for encrypting an IP packet communicated based on an internet protocol is provided. The packet encryption saves fragment information included in an IP header in an area other than the IP header, clears the fragment information included in the IP header, encrypts the IP packet in which the fragment information included in the IP header is cleared, and outputs the encrypted IP packet. | 10-01-2009 |

| 20080241047 | SURFACE MODIFYING CARBON NANOTUBE MATERIAL, MANUFACTURING METHOD THEREFOR, ELECTRONIC COMPONENT AND ELECTRONIC DEVICE - A carbon nanotube material is exposed to ultraviolet rays, and a silicon-containing compound capable of modifying the surface of the carbon nanotube material in combination with the ultraviolet rays is supplied to thereby modify the surface of the carbon nanotube material. | 10-02-2008 |
| 20090221130 | N-TYPE SEMICONDUCTOR CARBON NANOMATERIAL, METHOD FOR PRODUCING N-TYPE SEMICONDUCTOR CARBON NANOMATERIAL, AND METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE - An n-Type semiconductor carbon nanomaterial is produced by mixing a substance having a functional group such as an amino or alkyl group with an inert gas and reacting a semiconductor carbon nanomaterial with the mixture under irradiation with VUV to covalently bond the amino or alkyl group to the carbon nanomaterial. The amino or alkyl group covalently bonded to the semiconductor carbon nanomaterial serves as electron-donating groups to convert the carbon nanomaterial into an n-type one. According to the invention, since the electron-donating group is covalently bonded, a stable n-type semiconductor carbon nanomaterial is obtained which little changes into a p-type one. Further, since the n-type semiconductor carbon nanomaterial is produced by a dry process, bundling or inclusion of impurities can be suppressed. Therefore, the uniform n-type semiconductor carbon nanomaterial having high reliability and stability can be produced. | 09-03-2009 |
