  • Patent number: 10746097
    Abstract: A compressed air energy storage power generation device includes a first heat exchanger, a heat storage tank, a second heat exchanger, a heating unit, a first power distributor, and a controller. The first heat exchanger performs heat exchange between the compressed air from a compressor and the heating medium. The heat storage tank stores the heating medium heatexchanged by the first heat exchanger. The second heat exchanger performs heat exchange between the compressed air from an accumulator tank and the heating medium from the heat storage tank. The first power distributor distributes the generated power of the power generator to a power system and the heating unit. When the internal pressure of the accumulator tank reaches a predetermined pressure and the generated power is larger than the power demand, the controller supplies a part or all of the generated power to the heating unit by the first power distributor.

  • Patent number: 10450735
    Abstract: In a flush toilet, a base plate, in which a function unit is installed, is provided on a recessed portion formed on a rear upper surface of a toilet bowl of a toilet main body. Hole portions that are open downward are provided in the recessed portion. The base plate is provided with bottomed protrusion portions fitted into the hole portions and accommodates a part of the function unit. Flow channels are provided between the base plate and the recessed portion, so that water inside the toilet bowl is discharged to a floor surface from the flow channels from the hole portions before the water overflows.

  • Patent number: 5187688
    Abstract: A passage is periodically scanned by a plurality of ultrasonic transmitters/receivers (sensors) arranged on the ceiling of the passage in two lines to calculate the height of an object to be measured to each sensor and the presence or absence of the measured object(s), moving direction(s) thereof, and the number thereof are reckoned from changes in sensed height and sensing time for each sensor induced by passing an object to be measured through the passage, and the position and a change in position with time of each sensor which senses the measured object concerned to count the number of passers-by in each moving direction. The presence or absence of the object to be measured and the number to be counted are decided in accordance with changes in sensed position and sensed height and the interrelation thereof, so that the number of sensors can be reduced and the number of passers-by can be counted at a high accuracy even when a plurality of persons pass under the sensors in a group.
