摘要： 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.

摘要： A powder container includes a rotatable powder storage to store powder for image formation, a conveyor to transport the powder inside the powder storage, and a scooping portion to scoop the powder inside the powder storage. The conveyor transports the powder in a powder conveyance direction parallel to a rotation axis of the powder storage toward an opening at one end of the powder storage. The scooping portion causes the powder to flow to the opening. The scooping portion includes a scooping face extending from an inner face of the powder storage toward the rotation axis of the powder storage, and a rim disposed along an inner end of the scooping face in a diameter direction of the powder storage, and at least a portion of the rim protruding downstream beyond the scooping face in a rotation direction of the powder storage.
