Patent ID: 7217399

Claim:
A reaction apparatus for treating an object with a gas, comprising: a treatment section which includes at least a treatment gas injection section, an inlet for the object and an outlet for the treated object, and a structure in which the object is automatically conveyed from the inlet to the outlet and is treated with the gas in a hermetically sealed space, said treatment section further including a mechanism for holding the object in a gas atmosphere in the treatment section in a fixed place for a desired time and a mechanism for moving or swinging the object to prevent unevenness of the treatment; a conveying mechanism for conveying the treated object from the outlet of the treatment section to the outside of the apparatus; at least two operation pieces disposed back and forth in a direction orthogonal to an advancing direction of the object in the treatment section to freely move up and down, wherein the two operation pieces are constituted of a first operation piece positioned on the inlet side of the object to be treated, and a second operation piece positioned on the outlet side of the treated object; the first operation piece holds the object in a fixed place for a desired time to treat the object with the gas for a desired time, and then the first operation piece is raised to lower the object toward the outlet by a desired distance; and the second operation piece receives the object passed through the raised first operation piece, holds the object in a fixed place for a desired time to treat the object with the gas again for a desired time, and then the second operation piece is raised to lower the object toward the outlet.
