A retainer for securing the outer air seal assembly of a turbine rotor stage in a locked position. The outer air seal is suspended from the turbine casing over the rotor stage and is locked to the casing by annular segmented locking keys. A series of circumferentially spaced seats are located upon the front face of the locking key segments with the outer surfaces of the seats describing a circle approximating a first diameter. A split ring retainer is slidably carried in a radially disposed groove and is arranged to secure the key segments in a locked position.

A mobile communication system includes using a mobile terminal, base stations and a base station control device. Each, each of the base stations cover respective areas for mobile communication service and is capable of relaying a conversation, made by the mobile terminal, by radio communication. The base station control device observes (or monitors) traffic (i.e., number of calls in progress) with respect to each of the base stations. In response to a conversation start event or a conversation end event that takes place in the mobile terminal which is located in an area of a base station whose traffic is large, the base station control device searches a surrounding base station whose traffic is relatively small. The base station control device then controls an area of the searched base station to enable radio communication with respect to the mobile terminal. For example, output of the searched base station is increased so that an area of the searched base station is broadened to cover a location of the mobile terminal. Thus, it is possible to avoid occurrence of call failure due to shortage of communication lines.
