A process for enriching a crude ammonia stream having moisture andor metal impurities andor gas impurities therein. Thus, deterioration in resource use efficiency can be prevented, and a switch to a high transmission rate for another mobile station requiring the high transmission rate can be smoothly performed, thus the throughput quality can be maintained. An internally specified filter is applied to the information to determine if the loan consumer meets a set of loan criteria. Transceiver circuitry may be connected to the resonating elements by transmission lines such as coaxial cables. After this pretreating process, the composite is plated with a metal and becomes most suitable for use as a material for heat sink on hybrid ICs since it can be efficiently soldered and has better corrosion resistance. The beacons transmit identifying information that the target device can use to determine the identity of the beacon.
