  • Publication number: 20090151063
    Abstract: A toilet flushing apparatus for firmly discharging a filth by a small amount of flush water and by a short period of time and still having a flush sound. The toilet flushing apparatus includes a first water supply supplying flush water to a toilet bowl of a toilet main body, a second water supply additionally supplying the flush water, a drain flow path communicated with a downstream side of a water seal portion of the toilet main body, an air sucking mechanism sucking air from the drain flow path, and a control apparatus controlling the first and second water supplies and the air sucking mechanism. The control apparatus produces a siphon operation by operating the air sucking mechanism continuous to operate the first water supply and to open an opening/closing valve through which flush water from the second water supply enters the toilet bowl, after forming a swirl flow inside the toilet bowl and before finishing the siphon operation.

  • Patent number: 7457632
    Abstract: A wireless base station unit (100) monitors total transmission power, which is a sum of transmission power to all of mobile station terminals (200-203) connected for communication. When the total transmission power exceeds a first threshold value, which is a criterion for judging whether to reduce the transmission power or not, an upper limit value of the transmission power to the mobile station terminal at the lowest priority level is reduced by a prescribed quantity. When the total transmission power exceeds a second threshold value, which is larger than the first threshold value, communication connection with the mobile station terminal at the lowest priority level is cut.
