A cathode active material for nonaqueous electrolyte secondary battery is provided. The recordingreproducing apparatus labels the content stored on a recording medium, and includes a control unit that acquires label information for labeling the content. In an embodiment, in a first position of a coupling between the first part and the second part, these parts can pivot via the electric drive. The method of the present invention enables the detection of nucleotide variations, such as resulting from base changes in target nucleic acid heteroduplex molecules derived from wildtype and mutant homoduplexes . The disclosed cycle stealing delay elements are programmable, and enable clock skew between individual distribution sinks.
