Patent number: 8077811Abstract: For each of a plurality of control channels, a likelihood indicated by a state metric of each state at the last point which is obtained at the time of Viterbi decoding is obtained. This Viterbi decoding is not cut off and performed to convolutionally coded data of the corresponding control channel. The ranking of the likelihood is obtained as a possibility ranking SM0RANK indicating the possibility of the control channel to be a control channel for a particular receiving apparatus. From the plurality of control channels, the control channels with the possibility ranking SM0RANK more or equal to a predetermined threshold are selected as candidate channels. An output likelihood of each candidate channel which is obtained in the Viterbi decoding is normalized with a receiving intensity of the corresponding candidate channel to detect a candidate channel having the highest normalized output likelihood as the control channel for the receiving apparatus.Type: GrantFiled: February 13, 2009Date of Patent: December 13, 2011Assignee: Renesas Electronics CorporationInventor: Masakazu Shimizu

A multiplicity of distributed holes are formed in the partition plate through which distributed holes secondary air is supplied from the air supply chamber to the combustion chamber. A flame rod facing to an upper side of a part of the rich-lean burners stops combustion when the flame rod does not detect any flames owing to a flame lift at a time of an oxygen deficiency. A supply quantity of the secondary air to the part of the rich-lean burners to which part the flame rod faces is larger than those to other parts.Type: ApplicationFiled: May 23, 2011Publication date: December 8, 2011Inventor: Masakazu Shimizu
