A storage rack post protector for use in absorbing and dissipating direct impact loads and deflecting indirect or off-center loads to the column frame on which it is attached or located adjacent to, consisting of a material with greater flexibility and compressibility that the rack itself and formed into such a shape as to deflect impact loads. The e-mail file sent by the sending party is properly or improperly delivered to a recipient e-mail address and stored in a data storage location of a recipient computer system. Information is read from the memory card and transferred to an information input device controller. The image processing information is stored in a file in which the image data is stored, or it is stored in another file. Therefore, even when the conductive brazing material leaks, then the conductive brazing material is not retained on the silver sulfide coating, and no influence is exerted on the driving operation of the discharge head.
