Publication number: 20170235052Abstract: An optical fiber holder includes a holder main body, a V-groove which is formed on an upper surface of the holder main body and accommodates a first optical fiber, a recessed groove which is formed on a same straight line with the V-groove and accommodates a second optical fiber having a coating portion with a larger outer diameter than the first optical fiber, and an abutting portion which is provided on an end portion of the recessed groove on an opposite side to the V-groove and includes an opening portion which has a smaller width than the recessed groove. When the second optical fiber is accommodated in the recessed groove, a fiber core wire of the second optical fiber protrudes to an outside via the opening portion and an end portion of the coating portion of the second optical fiber abuts on the abutting portion.Type: ApplicationFiled: February 10, 2017Publication date: August 17, 2017Applicant: SEI OPTIFRONTIER CO., LTD.Inventors: Shinsuke KURINO, Hiroshi TAKAYANAGI

Patent number: 8196011Abstract: Input data (1A) having an integral multiple of 8 bits is divided into symbols in units of b bits (b is an integer of 5 to 7) in a register file 10, an error detecting code is added in an error detection calculation circuit 20, and then encoding (such as Reed Solomon (RS) encoding) having an error correction capability of two or more symbols is performed in a parity calculation circuit 30 to record the data in a storage 40. In the reproduction, error correction in units of symbols is performed to reproduced data from the storage 40 in an error correction circuit 70, error detection processing is performed in an error detection calculation circuit 80, and then data having the integral multiple of 8 bits is recovered in a register file 90 to output the same. By this means, it is possible to provide a storage system with high reliability to a soft error that occurs in a storage such as semiconductor memory.Type: GrantFiled: February 15, 2006Date of Patent: June 5, 2012Assignee: Hitachi ULSI Systems Co., Ltd.Inventors: Morishi Izumita, Hiroshi Takayanagi
