Abstract: An inflation molding device includes a viscosity estimation unit that estimates a viscosity of a bubble discharged in a substantially cylindrical shape from a die, a temperature identification unit that identifies a temperature of the bubble, and a parameter estimation unit that estimates a viscosity parameter of the bubble based on the viscosity of the bubble estimated by the viscosity estimation unit and the temperature of the bubble identified by the temperature identification unit.

Abstract: A film molding device includes: a cooling unit that cools a molding material discharged from a mold; and a rectifying unit that rectifies cooling air blown out from the cooling unit. The rectifying unit includes a suction portion that suctions the cooling air.

Abstract: Stabilization of a stage in a movable stage apparatus is enhanced, and increasing in size of the movable stage apparatus is suppressed. A reaction force cancel system is provided in the movable stage apparatus where a stage moves on a surface plate installed on a floor via a vibration-isolating spring, and cancels a reaction force generated on the surface plate upon movement of the stage. The reaction force cancel system includes a reaction force canceling actuator for applying a counter-thrust that is a force for reducing the reaction force to the surface plate. The reaction force canceling actuator is arranged at a lower position than a top surface of the surface plate so that the surface plate hangs over the reaction force canceling actuator.
