Filed: 1993-06-30
Abstract: PURPOSE:To guarantee the high quality of a glass substrate subjected to heat treatment and to apply the heat treatment in high productivity by an overall treatment. CONSTITUTION:Plural glass substrates W are supported with a cassette 9 and contained in a far infrared radiation vessel 7. The far infrared radiation vessel 7 is housed in a furnace body 2 and the glass substrates W and the cassette 9 are substantially closed into the far infrared radiation vessel 7 and shielded from the furnace body 2. In the inner surface of the furnace body 2, the far infrared radiation heater 5 is arranged and the far infrared radiation H from the heater 5 heats the glass substrates W through a far infrared radiation material layer 17. As the glass substrates W are contained in the far infrared rediation vessel 7 by the substantially closed condition, flowing of the air in the device by the natural convection is not developed and the decline of accuracy of the temp. distribution in the vertical direction caused by the natural convection and the stickiness of scattering dust to the glass substrates W are not developed. Further, the unevenness of heat treatment temp. can be reduced by the indirect heating through the far infrared radiation material layer 17.

When compressed air is charmed from the air conduction pipe 29 into the branch pipe 32, the agent is scattered in the excavated soil which is being transferred in an auger screw 21 to be accurately agitated in the auger screw. Water in the excavated soil is rapidly absorbed by the water-soluble polymer in the agent and mud particles are coagulated by the inorganic ion-effect.  And hence, muddy soil can be smoothly and efficiently conveyed without clogging to the auger screw 21 or the soil pool 35 or without choking the soil-discharge pipe 36.
