Patent number: 8613560Abstract: An optical connector plug is comprised of a pair of divided front and rear housings formed generally in a quadrilateral tubular shape for receiving a ferrule to hold an optical fiber. A housing, one of the housings is provided with engagement openings on at least opposite wall portions thereof, and the other housing is provided with engagement projections on its opposite wall portions to be engaged in the engagement openings. Furthermore, fitting projections are formed in the longitudinal direction on the wall portions in which the engagement openings are formed, and fitting recesses to be fitted with the fitting projections are formed in the wall portions on which the engagement projections are formed. The pair of housings are firmly joined to each other by engaging the engagement projections with the engagement openings and by fitting and engaging the fitting projections in the fitting recesses.Type: GrantFiled: April 26, 2010Date of Patent: December 24, 2013Assignee: Adamant Kogyo Co., Ltd.Inventors: Nobuhiko Oda, Isao Yamauchi, Kohsuke Ishikawa

Patent number: 8209604Abstract: Systems and methods for manipulating mathematical expressions in a computer system. A system can include a builddown module programmed to builddown a mathematical expression from a two-dimensional format to a linear format, the builddown module being programmed to associate a special property of the two-dimensional format of the mathematical expression with a corresponding character of the linear format of the mathematical expression. A method can include receiving a request to builddown the mathematical expression from a two-dimensional format to a linear format, building down the mathematical expression to the linear format, and associating a special property of the two-dimensional format of the mathematical expression with a corresponding character of the linear format of the mathematical expression.Type: GrantFiled: September 16, 2005Date of Patent: June 26, 2012Assignee: Microsoft CorporationInventors: Murray Sargent, III, Jennifer P. Michelstein, Ethan Joseph Bernstein, Said Abou-Hallawa, Isao Yamauchi
