Abstract: A sealing device of this invention is designed to prevent entering of the open air through a coupling of a process tube of a CVD apparatus. The sealing device includes a first flange having a mirror-finished face, a second flange having a face which is brought into contact with the face of the first flange, at least one gas guide which is open to at least one of the faces of the first and second flanges and an evacuation system for evacuating a region, in which the first and second flanges are brought into contact with each other, through the gas guide.

Abstract: A method of attaining a uniform flow in an elongated fluidized bed furnace, used for the purpose of preventing the expansion and uniting of bubbles in the fluidized bed, and setting the fluidized bed in a uniform flow state, so as to keep the flow condition of the bubbles excellent at all times. The purpose of this method can be achieved by withdrawing a fluidized gas from an arbitrary portion of a fluidized bed (13) through a fluidization gas venting or purging means (A).

Abstract: Fluidized-bed type carburizing furnace means of the class provided with a path for circulation of the furnace gas of a fluidized-bed type carburizing furnace is improved by incorporation therein of ejector means for spouting compressed gas into the circulation path. The circulation path comprises an outlet pipe emanating from the furnace gas outlet of the fluidized-bed type carburizing furnace, a cyclone connected through the medium of the outlet pipe to the fluidized-bed type carburizing furnace, and a discharge pipe emanating from the cyclone and joined to the furnace gas inlet of the fluidized-bed type carburizing furnace. The ejector means comprises a constriction formed in the discharge pipe and a feed pipe for compressed gas having the leading end thereof inserted into the constriction.

Abstract: A heat treatment apparatus for metals or metal articles has a fluidized-bed furnace for heating the metals and a cooling chamber disposed above the furnace so as to communicate with a heating chamber of the furnace through a partition capable of being opened and closed, so that the metals can be cooled immediately after heated. The apparatus further includes a circulating circuit arrangement with a heat-resisting fan for circulating together or separately heated furnace gas and cooling fluid. Flow rate of the circulating furnace gas and/or cooling fluid is controlled by a flow rate control device provided in the circulating circuit.

Abstract: An incineration equipment for removing organic substances from various parts of an extruder in a plastics forming machine, has a combustion chamber formed in the upper portion of a heating furnace accommodating a fluidized-bed consisting of refractory particles therein, into which furnace the various parts are to be thrown, and a burning system for heating the fluidized-bed and also for causing gaseous decomposed polymers produced by thermal decomposition of the organic substances and mixed with air fed from the bottom of the furnace through a porous dispersion plate to burn in the combustion chamber. This burning system connects through a single directional control valve with a fuel tank and an air tank, and it comprises a burner having its tip end opened in the combustion chamber, and a temperature sensor for sensing the temperature in the furnace and outputting an operation signal for actuating the directional control valve in accordance with the sensed furnace temperature.
