Publication number: 20110142066Abstract: A master node (12) sends an identification signal for designating a communication channel in an identification signal time slot. When the own node matches the node in which the communication channel designated by the identification signal sent from the master node (12) is set in the identification signal time slot, the master node (12) and slave nodes (131 to 13n) each perform data transmission via the communication channel, based on the set contents of the communication channel, in the data transmission time slot corresponding to the identification signal time slot in which the identification signal has been sent.Type: ApplicationFiled: April 20, 2009Publication date: June 16, 2011Applicant: Nat'I Inst of Advanced Industrial Sci and TechInventors: Yuji Kasai, Eiichi Takahashi, Masahiro Murakawa, Tetsuya Higuchi

Publication number: 20050107262Abstract: A recording method that records information in soliton units, a computing method that performs a computation, an information transmission method, an energy storage method, a magnetic flux measurement method and a quantum bit constitution method utilize the properties of phase solitons manifested between superconducting order parameters present in multiple bands in a superconductor having a multiple bands. The phase difference soliton is maintained, so information can be stored in the form of phase differences. Moreover, ??soliton phase slip will also be present when the same energy is carried in the reverse direction, so the soliton itself can have a + or ? sign. The soliton enables storage of energy not accompanied by magnetic flux. Also, with soliton units, magnetic flux can be measured with greater precision by discriminating external magnetic flux. Moreover, using solitons and anti-solitons makes it possible to constitute quantum bits required in quantum measurements.Type: ApplicationFiled: October 10, 2002Publication date: May 19, 2005Applicant: Nat.
