In a semiconductor bare chip on the front surface whereof is formed an integrated circuit, a magnetic loss film 55 is formed on the back surface of that semiconductor bare chip. Scripts and a preprocessor are used to convert filenames and template filename references into actual names. The liquid supply unite 1 includes a degassing unit 21 which suppresses the generation of the bubble in the liquid 50. These magnetic nanoparticles are arranged into data tracks to store information through encapsulation within the carbon nanotubes. For example, a data decoder circuit is discussed that includes an input memory, a data decoder operable to decode data from the input memory in one or more iterations, an output memory operable to store decoded data from the data decoder, and a test port operable to provide access to the input memory, the data decoder and the output memory. The overall crutch adapts ergonomically to the needs and comfort of the patient and is adjustable by the user for that comfort yet is readily and inexpensive to manufacture through the use, where possible, of standard components.
