Title: Fiber drawing furnace
Inventor: MASUDA ISAO
IPC: C03B37/027
Filed: 1987-10-30
Abstract: PURPOSE:To enable stable drawing of fiber by constituting a fiber drawing furnace so that the disturbance of inert gas flow being introduced is prevented with a middle shutter and generation of convection in the inside of the furnace body is prevented with a heater for regulation. CONSTITUTION:In the inside of the furnace body 1 of a fiber drawing furnace, the disturbance of inert gas being introduced is prevented with a shutter 18 of the middle part and generation of convection resulting from the temp. gradiation in the inside of the furnace body 1 is prevented with a heater 24 for regulation. Thereby the temp. fluctuation in a fiber molding part can be extremely inhibited and fiber drawing can be performed uniformly and stably. Furthermore, in an introduction hole of a preform 2 in the upper end of the furnace body 1, the interval between a cylindrical material 9 for supporting the preform and the furnace body 1 is sealed with an O-ring 12. Therefore, the furnace body 1 can be surely sealed regardless of scattering of the outer diameter of the preform 2 and distortion of the shape. Therefore, the temp. fluctuation resulting from outflow of inert gas can be inhibited and stable drawing of fiber 4 can be performed.

Abstract: PURPOSE:To provide an air conditioner for a vehicle, which can delivery the air without reducing the air-flow very much for the front seats and also can make the temperature of the air at a rear foot take-off port relatively higher than that of the air at a front foot take-off port. CONSTITUTION:Four partition plates 19 are arranged down a heater core 4 in the direction normal to the paper so as not to overlap each other. Among the five passages separated by these partition plates 19, the second passage 20 and the fourth passage 20 are faced to a rear foot take-off port 18 respectively. And, cool air cut-off plates 22 are arranged in the second passage 20 and the fourth passage 20. When an aperture of an air mixing damper is located in the position faced to the cool air cut-off plate 22, the cool air does not flow into the rear foot take-off port 18 and the heated air alone flows in from the heater core 4. Since the heated air and the cool air flow toward a front ventilator, temperature of the air at the front foot take-off port becomes lower than that of the air at the rear foot take-off port 18.
