The present invention provides a voltage divider circuit capable of reducing a number of external devices and lowering the cost and power consumption. The parking brake anchor includes an anchor body and an abutment. The folder creating portion creates a first folder that the application program uses, in the first storage area, and the mount processing portion mounts the second storage area on the first folder at the time of initializing the information processing device. The method includes the steps of: a) dissolving a purified p-phenylenediamine free base derived from the short path distillation process in an organic solvent; b) contacting the dissolved free base distillate with an appropriate mineral acid; and c) crystallizing the color developer in the acid salt form.
