Forces and moments are detected in a distinguishing manner by a simple structure. The main body includes a guide used to guide the toner. The phase information is sent from the second device to the first device. Also in a preferred embodiment, the key recovery block is sent as part of an Internet Message Control Protocol message. When activating the exhaust purification catalyst, the fuel fed from the fuel injector is used to heat the small-sized oxidation catalyst and when the exhaust purification catalyst is further raised in temperature, the fuel fed from the fuel feed valve is increased and reformed fuel is exhausted from the small-sized oxidation catalyst. The phage are amplified in mutator media containing the modified phosphate.
