Publication number: 20150229329Abstract: An object is to enable erasure correction even at the time of a degeneration operation and reduce the number of necessary parallel media through dynamic setting of degree of redundancy. A parallel data encoding/decoding system performs parallel data transmissions using a plurality of lanes from an encoder to a decoder. The encoder encodes products of elements of an encoding vector M of symbols of each lane and a state vector U indicating validity of the symbols, and transmits the state vector U along with a transmission vector Y obtained through the encoding. The decoder decodes a subset Msub constituted of valid elements of the encoding vector M using a received reception vector Y?, the received state vector U, and an erasure vector E indicating whether each element of the transmission vector has been erased in a transmission/reception section.Type: ApplicationFiled: September 6, 2013Publication date: August 13, 2015Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Yoshiaki Yamada, Mitsuhiro Teshima, Kei Kitamura, Kenji Hisadome

Patent number: 8007968Abstract: In the present invention, patterning for the first time is performed on a film to be worked above the front surface of a substrate, and the actual dimension of the pattern formed by the patterning for the first time is measured. Based on the dimension measurement result of the patterning or the first time, the condition of patterning for the second time is then set. In this event, the condition of the patterning for the second time is set so that a difference between the dimension of the patterning for the first time and its target dimension is equal to a difference between the dimension of the patterning for the second time and its target dimension. Thereafter, the patterning for the second time is performed under the set patterning condition.Type: GrantFiled: July 25, 2007Date of Patent: August 30, 2011Assignee: Tokyo Electron LimitedInventors: Yoshiaki Yamada, Tadayuki Yamaguchi, Yuuichi Yamamoto, Yasuhito Saiga, Kazuo Sawai
