Heating apparatus
First Claim
1. A heating apparatus for curing films coated on workpieces, the apparatus comprising:
- a base plate having an opening defined therein which is connected to an evacuating device;
a workpiece holder disposed over said opening for holding workpieces;
a reaction chamber vertically movable with respect to said baseplate between a lowered position in which said reaction chamber defines a closed space which accommodates the workpieces therein and a lifted position in which the workpieces are exposed out of the reaction chamber;
a heating device vertically movable with respect to said base plate between a lowered position in which the heating device surrounds said reaction chamber for heating the reaction chamber to cure films coated on the workpieces and a lifted position in which said reaction chamber is exposed out of the heating device;
means for vertically moving said reaction chamber with respect to said workpiece holder between said lowered and lifted positions of the reaction chamber; and
means for vertically moving said heating device independently of said reaction chamber between said lowered and lifted positions of said heating device.

Abstract
A plurality of workpieces are supported on a workpiece holder disposed over an opening defined in a horizontal base plate and connected to an evacuating device. A reaction chamber, which is supported on an arm of a lifting and lowering device, is vertically movable with respect to the base plate between a lowered position in which the reaction chamber defines a closed space which accommodates the workpieces therein and a lifted position in which the workpieces are exposed out of the reaction chamber. A heating device, which is supported on an arm of another lifting and lowering device, is vertically movable with respect to the base plate between a lowered position in which the heating device surrounds the reaction chamber and a lifted position in which the reaction chamber is exposed out of the heating device.

17. A heating apparatus for heating workpieces to cure films coated on the workpieces, the apparatus comprising:
-
holder means for holding the workpieces; a reaction chamber for accommodating said holder means with the workpieces held thereby, said reaction chamber being movable to a position in which the workpieces are exposed out of the reaction chamber; electrode means disposed around said reaction chamber for generating a plasma in the reaction chamber; heater means for heating said reaction chamber in covering relationship thereto to cure films coated on the workpieces, said heater means being movable to a position in which the reaction chamber is exposed out of the heater means; means for vertically moving said reaction chamber with respect to said holder means; and means for vertically moving said heater means with respect to said reaction chamber independently of said reaction chamber moving means. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. Apparatus for curing films on workpieces, comprising:
-
holder means for holding workpieces having films coated thereon; a reaction chamber for accommodating said holder means with the workpieces held thereby; means for evacuating the reaction chamber to dry the coated films on the workpieces; heater means for heating said reaction chamber in covering relationship thereto to cure the dried, coated films on the workpieces; and means for vertically moving said reaction chamber and said heater means between lowered positions in which the reaction chamber and heater means are disposed about the holder means and lifted positions in which said reaction chamber and said heater means are not disposed about said holder means, said moving means being adapted to move said reaction chamber and said heater means independently of each other. - View Dependent Claims (25)
