Abstract: A mobile communication system having a base station and a mobile station, provided with indoor and outdoor antennas in different locations of a building structure that substantially prevents penetration of electromagnetic radiation. A communication unit is connected between the indoor and outdoor antennas. The communication unit is arranged to detect a signal received at the indoor antenna from the mobile station while the mobile station is communicating with the base station, determines that the mobile station is entering the structure when the detected signal exceeds a predetermined reference level and establishes a radio link between the outdoor antenna and the base station and a circuit between the indoor and outdoor antennas and commands the mobile station to establish a radio link to the indoor antenna. The radio link established between the mobile station and the indoor antenna uses forward and reverse channels that avoid interference with other mobile stations.

A plurality of guide members are circumferentially mounted on the peripheral surface of the turn table, and a plurality of bottle inspecting stations are disposed circumferentially and spaced equally therearound. The inspecting stations include a down sealing surface measuring station for measuring the down sealing surface of the lip portion of each bottle, an outer diameter and perpendicularly measuring station for measuring outer diameters of the various portions of each bottle and an inner diameter measuring station for measuring the inner diameter of the lip opening. The bottles inspected or measured are conveyed out of the conveying passage and selectively divided into defective bottles and satisfactory bottles.
