A magnetic stripe reader apparatus comprises a first casing, a second casing, a magnetic stripe reader unit, and at least a connecting element. A path is determined by a tracking point for at least one vehicle image. A temperature sensor for recording a chip temperature of the integrated semiconductor memory is connected to the control circuit. In particular, this invention relates to a catalyst precursor compound represented by the formula:. The method comprises rotating the basket at a first rate of rotation, spraying water into the basket while the basket is rotating at the first rate, and rotating the basket at a second rate of rotation, the second rate of rotation greater than the first rate of rotation. The method of operating the engine, which is capable of stepwise or continuously correcting a burning state through fuel regulation including the cutoff of fuel, upon occurrence of abnormal combustion, executes a stop or output limit operation on the engine.
