A method and computer system for analyzing a text corpus in a natural language is provided. Suitably, hydrogen or a hydrogen-containing gas mixture is confined at the interface of tool and workpieces at the machining site. At electronic data storing step S3, the character box data read at the photoelectric transducing S2 is stored. Data may be transmitted between downstream ports based upon routing information for transmitting data from the upstream port to each of the downstream ports. In other embodiments, the physiological cooling agent is present with menthol and menthone and coated chewing gum has a coating that comprises a physiological cooling agent. The fixed layer includes a first ferromagnetic layer having a CoxFe interface layer and a Co-based amorphous metallic layer between the CoxFe interface layer and the insulating barrier layer, an antiparallel coupling layer below the first ferromagnetic layer, and a second ferromagnetic layer below the antiparallel coupling layer.
