    摘要： A tunnel boring machine for collecting earth excavated upon rotation of a cutter disk includes a non-pressurized chamber behind the cutter disk for collecting earth excavated by the cutter disk and discharging the earth with a carrying fluid. The machine includes a first open tank arranged in the non-pressurized chamber which serves as a vessel for containing the carrying fluid as well as a hopper for collecting excavated earth. Carrying fluid supply apparatus is provided for supplying the carrying fluid to the first open tank and suction/discharge apparatus is provided for sucking and discharging the carrying fluid supply to the first open tank rearwardly together with the collected earth. Water level control apparatus provided for monitoring a water level of a carrying fluid in the first open tank and keeping the water level between a minimum water level and a maximum water level.

    摘要： A temperature measuring device, which is used in a continuous casting machine, measures the surface temperature of a part or all of a cast slab in a width direction of the cast slab, which is drawn from a mold and conveyed by rollers, in a secondary cooling zone of the continuous casting machine. The temperature measuring device includes a support member that is installed on the side of roller support parts by which the rollers are rotatably supported; an arm member of which a proximal portion is rotatably mounted on the support member; and a radiation thermometer which is provided at a distal end portion of the arm member and of which a light receiving opening is disposed at a position corresponding to a height in the range of 1.0 to 4.5 m from the surface of the cast slab.
