    • A mobile communication system using an adaptive multiantenna realizes improvement of reception characteristics, effective use of the band, and optimization of the throughput in comparison with a system in which application of the same multiantenna communication method is continued irrespective of a variation of the number of radio relay stations. The mobile communication system comprises a radio base station, a radio relay station, and mobile terminal stations for communicating with the radio base station through a radio relay station. The radio base station has a multiantenna and is characterized in that the radio base station judges if there is any variation of the number of radio relay stations when the radio base station carries out transmission through a radio relay station, and the radio base station communicates with the mobile terminal station by switching the multiantenna communication method using the multiantenna depending on the delay time of the feedback signal from the mobile terminal station if there is a variation of the number of radio relay stations.

    • An instrument drive device configured in such a manner that a case body does not receive a load for press-fitting a pointer into a pointer shaft and that liquid, such as a lubricant, within the case body does not leak therefrom. An instrument drive device (1) comprises; a case body (12) provided with a first bearing section (13) and a second bearing section (14) which are through sections; a pointer shaft (6) pivotably supported by the first bearing section (13) and the second bearing section (14) and having a part which protrudes to the outside from the case body (12) and to which a pointer is mounted. The instrument drive device (1) is also provided with a bearing body (16) press-fitted into and held by the second bearing section (14) and restricting the movement of the pointer shaft (6) in the axial direction. The second bearing section (14) is provided with a shaft support section (14a) for pivotably supporting the pointer shaft (6), and also with a holding section (14b) into which the bearing body (16) is press-fitted and held. The diameter of the holding section (14b) is set to be smaller than the diameter of the shaft support section (14a).
