Abstract: PURPOSE:To improve considerably the workability when a die engaging part is attached or detached to or from a die in such constitution wherein the die engaging part approaches the die when the piston rod of the 1st cylinder extends and that the die engaging part clamps the die when the piston rod of the 2nd cylinder rotates. CONSTITUTION:Solenoid valves 39, 40 are changed over by a command for clamping to connect ports 29, 30 to a tank 44 and a port 31 to a pump 37 in the case of clamping a die 15 with a die engaging part 2. A piston 10 is therefore moved upward by an oil pressure. When the piston 10 arrives at the uppermost position, the part 2 is positioned upper than the top surface in the edge part of the die 15. Solenoid valves 38, 40 are then changed over to connect the ports 30, 31 to the tank 44 and the port 29 to the pump 37. A rack 4 is therefore moved leftward by the oil pressure, and a piston rod 11 rotates 90 deg. accordingly. The flat die engaging part 2 having a T shape is then rotated to the position where it is engaged with the die 15 and the die 15 is thus clamped.

In this case, the throttle lever 12 is drawn with the finger to obtain an engine rotating speed needed for operation. At this time, the throttle lever 12 is held at its position because of the friction of a friction washer even when the finger is put away from the lever 12 in a stroke of the throttle lever 12. Therefore, the operation is carried out by gripping only the brake lever 13 after the rotating speed of the engine is adjusted.

CONSTITUTION:Air extracting tubes 11 and 12 are respectively opened to the shell of the other condenser, being interposed by the primary open/close valves 13 and 13', in a condenser device of dual-pressure type of which exhaust sides 1a and 1b are connected to condensers 3 and 4 which are separately constituted from each other. The back-flow operation is taken place by flowing back the cooling water in a cooling water tube 5 in the direction as shown by arrow signs B. In these directions, the tubes 11 and 12 are connected to an air extractor device 9, running in parallel with each other, being interposed by the secondary open/close valves 14 and 14'. During the back-flow operation, the condensers 4 and 3 function as a high-vacuum stage condenser and a low-vacuum stage condenser, respectively. Accordingly, when the primary open/close valve 13 is opened while the same valve 13' is closed, and the secondary open/ close valve 14 is closed while the same valve 14' is opened, both condensers can function effectively even at the back-flow operation to remove adhered matters from the condensers and the cooling water tubes.
