An electrical power cord for providing low-voltage alternating current outputs from a high-voltage alternating current source. The modified blank cartridges each have a quantity of explosive substance sufficient only to cycle the firearm. Impurities present in the CVD system during formation of the epitaxial layer are gettered by the gettering wafers. Some sections are preferably hinged together, allowing different sections to adopt different inclinations as they travel about a non-level floor. A combination unit 58 generates a wide-range image by combining the subject image decided as the combination target with the images sequentially acquired by the image acquisition unit 52. The positive electrode active material includes: a small-diameter active material having an average particle diameter of about 0.
