Heating device used for a gas phase growing mechanism or heat treatment mechanism

Claim 2

A heating device used for a gas phase growing mechanism or a heat treatment mechanism comprising: a tubular reactor (1) made of a heat resistant and chemically inert material incorporating a support (6) having a plurality of workpieces (5) set and arranged thereon to be put to a gas phase growing or heat treatment, a cylindrically formed main heating furnace body (4) having open opposite ends, said cylindrical main heating furnace body being disposed so as to surround the outer circumferential surface of said tubular reactor (1) along substantially the entire length thereof, a pair of auxiliary heating furnace bodies separate from said main heating furnace body and each closing the respective longitudinal open ends of said cylindrical main heating body (4), whereby said cylindrical main heating furnace body and said pair of auxiliary heating furnace bodies cooperate to form a heating furnace confining said tubular reactor (1) therein.

Claim 3

A heating device, used for a gas phase growing mechanism or a heat treatment mechanism comprising: a tubular reactor (1) made of a heat resistant and chemically inert material incorporating a support (6) having a plurality of workpieces (5) set and arranged thereon to be put to gas phase growing or heat treatment, a cylindrical main heating furnace body (4) disposed so as to surround the outer circumferential surface of said tubular reactor (1) at the entire length thereof, and a pair of auxiliary heating furnace bodies each closing both longitudinal opening ends of said cylindrical main heating body (4), whereby said cylindrical main heating furnace body and said pair of auxiliary heating furnace bodies constitute a heating furnace confining said tubular reactor (1) therein and wherein the tubular reactor (1) has at one longitudinal end thereof an exhaust conduit (7) in communication with the inside and protruded from said one longitudinal end of said tubular reactor (1), and one of the auxiliary heating furnace bodies (4a, 4a) has a conduit insertion hole (4a1) extending therethrough for passing said exhaust conduit (7) to the outside.

Claim 4

A heating device, used for a gas phase growing mechanism or a heat treatment mechanism comprising: a tubular reactor (1) made of a heat resistant and chemically inert material incorporating a support (6) having a plurality of workpieces (5) set and arranged thereon to be put to gas phase growing or heat treatment, a cylindrical main heating furnace body (4) disposed so as to surround the outer circumferential surface of said tubular reactor (1) at the entire length thereof, and a pair of auxiliary heating furnace bodies each closing both longitudinal opening ends of said cylindrical main heating body (4), whereby said cylindrical main heating furnace body and said pair of auxiliary heating furnace bodies constitute a heating furnace confining said tubular reactor (1) therein and wherein the tubular reactor (1) has at one longitudinal end thereof an exhaust conduit (7) in communication with the inside and protruded from said one longitudinal end of said tubular reactor (1), and one of the auxiliary heating furnace bodies (4a, 4a) has a conduit insertion hole (4a1) extending therethrough for passing said exhaust conduit (7) to the outside.

Claim 5

A heating device as defined in claim 2, wherein the tubular reactor (1) has at the other longitudinal end thereof a transportation port (1c) for charge/discharge of the support (6) and a door (8) for opening and closing said transportation port (1c), and the other of the auxiliary heating furnace bodies (4a, 4a) is disposed to the outer side of said door (8).

Claim 6

A heating device as defined in claim 3, wherein the door (8) has a main part that protrudes in the direction from the other longitudinal opening end to the inside of the tubular reactor (1) and a flange (8b) disposed along the circumferential edge at the outer side of said main part and capable of intimate contact with a circumferential edge of the transportation port (1c) disposed at the other longitudinal end of the tubular reactor (1) and the other of the auxiliary heating furnace bodies (4a, 4a) is disposed in a recess of the protruding main part (8c).
