The dispensing assembly with a syringe comprising storage container configured to receive a powdery or granular material and a piston that is connected to a hollow ram. In the case, an airflow section which interconnects the inside of the tank and the inside of the case is formed in a higher side than a waterline of the float body at the seating time, and also at the seating time, this airflow section is restricted. A controller determines whether a request for data transfer from the data transmitter should be accepted, based on an address of the data transmitter and the registered e-mail addresses if the data transfer request is attached to the received data. The distal ends of the springs are releasably attached to spring connectors on the frame. An insulator is formed on at least sidewalls of the opening and a conductor is formed on the insulator. The channel estimate is used for channel compensation, and the phase of the channel is corrected using the channel estimate obtained from the pilot tones.
