摘要： PURPOSE:To effectively cool a plurality of metal plates so as to be immediately transferred to a processor by suspending a plurality of supporters from a circulating rail of a conveyor device and continuously cooling respective metal plates held by respective supporters while transferring them one after another. CONSTITUTION:Metal plates 5 are transferred by a carrying-in conveyor 9 and carried in a cold refrigerant 2 along a tilted table 23 of a supplying device 10 from a tilt part 3 of a insulated cooling tank 4 while being held by supporters 6. Then, the supporters 6 are delivered to a cooling conveyor 20 at a point E on the way where the supporters are transferred from a point A to a point B along a circulating rail 7, and is cooled during being transferred to a point F. After the supporters 6 are transferred from the point F to the point C through the point B, they are tilted toward a delivery conveyor 11 by a piston 25 of a delivery device 12. Thereby, the metal plates 5 are dropped from the supporters 6 and transferred to the delivery conveyor 11 with being sliding on a tilting plate 26. After that, the metal plates 5 are transferred to the next process, while empty supporters 6 are circulating and returned to the A point through the point D.

摘要： PROBLEM TO BE SOLVED: To continuously produce a gaseous mixture in the case of the stoppage of electric power by intermediately providing a cut-off valve opened by a operation gas in a 1st and 2nd gas supply passage and enabling to supply the operation gas from an auxiliary tank through a solenoid valve opened at the time of the breaking of power supply. SOLUTION: At the time of inputting a signal that the pressure in a buffer tank 7 is lowered to a controller 26 from a pressure gauge 10, the solenoid valve 25 for operation gas is opened by cutting-off the close signal S to the solenoid valve 25 for operation gas by the controller 26. And a part of a synthetic air in the auxiliary tank 14 is supplied to both cut-off valves 4a, 4b through a passage 24, a branched passage 24a and 24b to open the both cut-off valves 4a and 4b. As a result, the synthetic air is produced by supplying a prescribed flow rate of oxygen and nitrogen from the 1st and 2nd gaseous starting material supply passages 1, 2. And at the time of the stoppage of electric power, the synthetic air is produced by opening both solenoid valves 4a, 4b by the action of a spring or the like to open both cut-off valves by the synthetic air pressure.

摘要： PROBLEM TO BE SOLVED: To crush dry ice formed into a block and supply it quantitatively as a granular form by providing loosening mechanisms which deform a lining body to loosen dry ice into a granular shape or into a pellet shape and providing pull-up mechanisms which pull the lining body upward to gather granular dry ice to the central portion of the lining body. SOLUTION: A discharge port 3c is formed in a lining body 3 provided inside a heat-insulating hollow box 2, and a lower opening 2b is formed in the box 2. After the lining body 3 is packed with dry ice under the condition that the discharge port 3c or the opening 2b is closed, the lining body 3 is deformed by loosening mechanismgs 7 provided outside the lining body 3, and granular or pellet-like dry ice is supplied through the discharge port 3c and the opening 2b while loosening dry ice formed into a block. Further, by the action of pull-up mechanisms 16 for pulling the lining body 3 upward with the aid of elastic members, the dry ice is always gathered to the lower opening 2b at the central portion and is discharged without hitch because the lining body 3 is gradually pulled up in accordance with the discharge of the dry ice.
