摘要： PURPOSE:To control the belt-speed to save energy by calculating the time for an article to be conveyed to reach belt conveyors on the downstream side, and a desired belt-speed conforming to the conveying capacity, which should be maintained by the belt conveyors on the downstream side, based on the flow rate of a first belt conveyor, and transmitting the calculated time and belt-speed to driving devices. CONSTITUTION:The loading weight per unit length of limestone on a belt is detected by a load cell 10 of a weighing device 9 through a carrier-roller 12 and a frame body 11 provided on a belt conveyor 4, and a signal converter 13 transmits a weight signal. On the other hand, a signal converter 16 converts the belt-speed detected by a speed detector 15 to transmit it. A computing element 18 receives the weight signal and the belt-speed to convert the loading flow rate into a flow rate signal to transmit the signal. A control device 19 receives the flow rate signal transmitted by the computing element 18 of the weighing device 9 to calculate the time for the limestone to reach the tail parts of belt conveyors 5, 6, 7 on the downstream side and the adaptable belt-speed, and to transmit the calculated time and the belt-speed to respective operation commanding devices 20, 21, 22.

摘要： PURPOSE:To provide an effective gas sampling device which can detect the presence/absence of a leakage gas. CONSTITUTION:Isolation valves 21, SV2, and SV3 which maintain a sampling pipeline 2 in an airtight state are respectively installed in the vicinities of the starting and ending points of the pipeline 2. A gas to be inspected is enclosed in an extent to be inspected set between each isolation valve 21, SV2, and SV3 and the pressure of the gas to be inspected is detected every moment with a pressure sensor 23. A monitoring device 24 continuously monitors the detecting value of the sensor 23 for a prescribed period of time. The presence/absence of a leakage gas can be discriminated from the varying state of the detecting value of the sensor 23, because the detecting value varies when gas leakage occurs.
