Abstract

Abstract A vapor phase processing apparatus of the type wherein an article is heated to a preselected temperature for vapor phase processing, comprises a vessel containing a liquid having a boiling point at least equal to the preselected temperature, into and out of which the article is transported, and a heating device for boiling the liquid in the vessel to produce vapor. The heating device is provided, as the sole source of heat, at a base wall of the vessel in such a manner that the heating device is not exposed to the liquid in the vessel.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 153 words
A vapor phase processing apparatus of the type wherein an article is heated to a preselected temperature for vapor phase processing, said apparatus comprising: a vessel containing a liquid having a boiling point at least equal to said preselected temperature, into and out of which the article is transported, said vessel having a base wall having an inner surface inclined in only one direction with respect to the horizontal and sidewalls extending upward from the periphery of said inner surface; heating means for boiling said liquid to produce vapor, which is provided, as the sole source of heat, at said base wall of the vessel so as not to be exposed to said liquid in the vessel, said heating means including at least two side-by-side heating elements spaced apart in said only one direction on an outer surface of said base wall below said inner surface; and cooling means for condensing said vapor.
Claim 2
Dependent Claim 153 words
A vapor phase processing apparatus of the type wherein an article is heated to a preselected temperature for vapor phase processing, said apparatus comprising: a vessel containing a liquid having a boiling point at least equal to said preselected temperature, into and out of which the article is transported, said vessel having a base wall having an inner surface inclined in only one direction with respect to the horizontal and sidewalls extending upward from the periphery of said inner surface; heating means for boiling said liquid to produce vapor, which is provided, as the sole source of heat, at said base wall of the vessel so as not to be exposed to said liquid in the vessel, said heating means including at least two side-by-side heating elements spaced apart in said only one direction on an outer surface of said base wall below said inner surface; and cooling means for condensing said vapor.
Claim 3
Dependent Claim 26 words
The apparatus of claim 1, further comprising temperature sensing means and temperature controlling means associated with said temperature sensor means, for individually controlling said heating elements.
Claim 4
Dependent Claim 72 words
The apparatus of claim 1 wherein the apparatus includes trough means for receiving condensed vapor, which is inclined in the direction opposite to the direction of inclination of said inner surface of the base wall and which is provided at a lowermost portion thereof with aperture means for permitting the condensed vapor received in the trough means to drop therethrough onto the uppermost portion of said inner surface of the base wall.
