Abstract: A missile to be fired from a barrel contains a tail, a tail sleeve attached to the tail, a stop element fixed to the tail sleeve, and a movable structural part disposed at the tail. Fin assembly wings are provided and are to be released from a subcaliber launch position to an overcaliber functional position by the movable structural part moving toward the stop element through a given distance. A pressure area is disposed between the tail end surface and the movable structural part. A propellant gas enters the pressure area during the firing of the missile, for moving the movable structural part away from the tail end surface against the stop element after firing. Bearing shafts are supported by the tail sleeve, the fin assembly wings are configured as a wrap around tail fin assembly held about the bearing shafts.

Abstract: A purpose of the present invention is to improve a reception sensitivity when simultaneous transmitting/receiving operations are not carried out in a mobile communication apparatus capable of performing the simultaneous transmitting/receiving operations. The mobile communication apparatus, according to the present invention, is comprised of an antenna selector (13) for switching a connection between a first antenna A (11) and a second antenna B (12), and is selectively connected with a transmission system which contains a transmission-side filter (14) and a transmitting unit (16), and with respect to a reception system which contains a reception-side filter (15) and a receiving unit (17).
