A system and method that continuously extracts traffic load and speed on roads within the coverage area of a cellular network. A flange-shaped pressing stepped portion is formed on the upper periphery of the tank main body of the receiver tank. Each of the plurality of pixels includes a switching TFT, an EL driving TFT, a power source controlling TFT, and an EL element, and the power source controlling TFT controls a potential difference between a cathode and an anode of the EL element. According to the invention: at least one cooling pipe can be connected in a water-tight manner to the first distribution pipe ; the cooling circuit can be traversed by a coolant and has a first connection, which allows coolant to be supplied to the cooling circuit; and the cooling circuit has a second connection, which allows coolant to be evacuated from the cooling circuit. A second record corresponding to the reference identifier may be retrieved from a server information table. The texture and structure of the expanded products are controlled by manipulating a pre-expanded food formulation comprising hydrocolloid and moisture.
