A memory card comprising an magnetic random access memory array that comprises a plurality of magnetic memory cells and a controller coupled to the MRAM array. The fender length corresponds to the length of the watercraft likely to make contact with a dock, pier andor pilings. Prior to the permeation step, the other impurities, particularly the hydrocarbons, may be removed by oxidative catalysis and subsequent adsorption of the carbon dioxides and of the water produced. The substrate or electrodes of the SAW chip is etched by an etching gas introduced into the ion etching equipment. The minute solid particles are produced from larger solid particles of solid CIPC by micronizing the larger particles. The terminal connection section and the pressure-bonding section are configured as different parts, and a connection section in which the terminal connection section and the pressure-bonding section are connected in series in the order named from a tip side to a rear side in a long length direction is configured.
