  • Publication number: 20220209848
    Abstract: It is suppressed of a deterioration of communication quality of a service link (SL) due to a local propagation-loss increasing part in a radio propagation path of a feeder link (FL) between an aerial-floating type communication relay apparatus and a gateway (GW) station. When the local propagation-loss increasing part occurs in the radio propagation path of the feeder link between the gateway station and the communication relay apparatus or when an occurrence of the propagation-loss increasing part is predicted, the communication relay apparatus is moved to a position capable of suppressing or avoiding the deterioration of communication quality due to the propagation-loss increasing part in the radio propagation path of the feeder link.

  • Patent number: 11307515
    Abstract: A developing device includes a developer bearer, a developer regulator, a developer supply passage, and a stopper. The developer bearer includes a magnetic field generator and is configured to bear a developer containing toner and magnetic carriers and conveys the developer to a developing area by rotation. A stopper prevents the developer blocked by the developer regulator from moving to a surface of the developer bearer, while securing a supply path for passing the developer in the developer supply passage to the developer bearer between the stopper and an upper end of a side wall of the developer supply passage that is opposite to the developing bearer. A width of the supply path in a direction perpendicular to a direction of a rotation axis of the developer bearer is in a range of 7%-10% of a circumference of an outer diameter of the developing bearer.
