In producing aqueous microbiocidal solutions by oxidation of a water-soluble alkali metal bromide, an intolerable loss of active halogen species has been found to occur during a 10-day period immediately after the product solution has been formed. When the identification name and thread type of the source file are set via the GUI dialog box, the computer system acquires a source code template corresponding to that thread type, and reflects the identification name set via the GUI dialog box in that source code template. Multiple groups of orthogonal codes can also be obtained by orthogonal rotation of a given orthogonal code group as long as the given code group includes real number andor complex number elements. The light-emitting device can include an inorganic PL material that absorbs another portion of the light emitted from the light-emitting member and emits light having a third spectrum different than both the first and the second spectra. The outer collar has an inner face bounding and defining the shape of the bore. Plural position fixes are taken over time and forwarded to the central station.
