  • Patent number: 11109311
    Abstract: In a base station, in cases where a repeater device capable of performing radio communication with a communication terminal is in a control channel state to control entire communication, a site controller determines whether an internal temperature of the repeater device is equal to or higher than a preset first temperature threshold, and when the internal temperature of the repeater device is equal to or higher than the first temperature threshold, the site controller brings the repeater device from the control channel state to an unavailable state, after bringing another repeater device that is in an idle state where nothing is processed, to the control channel state. Thereafter, when the internal temperature of the repeater device becomes equal to or lower than a preset second temperature threshold and when a predetermined time is elapsed, the site controller brings the repeater device from the unavailable state to the idle state.

  • Patent number: 9265387
    Abstract: The present invention provides an electric incinerating toilet bowl and an incineration control method for the electric incinerating toilet bowl which can remove not only odor components but also smoke and soot generated when paper liners burn to thereby prevent the odor components and the smoke and soot from being exhausted. The incineration control method heats a smoke and soot removing filler layer to a smoke and soot removing temperature not lower than 350° C.
