摘要： PROBLEM TO BE SOLVED: To change the thickness of a mortal layer applied on the surface of outer circumference of an upper nozzle adequately by providing a nozzle moving means that is movable in the direction of up and down of the upper nozzle that is arranged to a turntable or approaching or separating from the upper nozzle. SOLUTION: The edge part of the applying nozzle 10 of an applying nozzle main body that is set at point P1 is moved at low speed to a point P2 injecting mortar and applies a predetermined quantity of mortar. When the applying nozzle 10 reaches the point P2 , the rising or moving of the applying nozzle 10 and the injection of mortar are stopped and the applying nozzle 10 retreats to a point P3 horizontally. After the retreat, the applying nozzle 10 descends to a point P keeping the state of stopping the injection of mortar. Then, the applying nozzle 10 moves from the point P4 to a point P5 at low speed injecting mortar, applies the predetermined quantity of mortar, moves from the point P5 to a point P6 at high speed and applies the predetermined quantity of mortar. As the result of this, the outer circumference on an introducing side is coated with mortar thickly and the discharging side is coated with mortar thinly.

摘要： The invention relates to an apparatus for pulling silicon single crystals, involving an upward pull, and in particular to a heat-insulating cylinder with improved heat-insulation characteristics. In addition, contamination of the silicon melt by graphite particles is to be avoided. According to the invention, a heat-insulating cylinder (8, 9, 21, 22, 23) in various configurations, preferably made of graphite, is provided. In order to avoid deleterious reactions between the SiO gas formed and the carbon heater (6), there is inserted, between the melting crucible (5) and the heater (6), a gas-screening cylinder (24) which forms a thin cylinder body consisting of wound carbon fibres which, in a shaping process, are given a cylindrical shape. The invention can be used in the production of silicon single crystals.

摘要： PURPOSE: To increase a mechanical strength by making a wall thickness larger at the portion where the bending moment of a wafer board holding portion becomes the largest and its neighboring portion over a particular portion of the overall length of the wafer board holding portion, and also giving essentially the same thickness in the potion other than said particular portion. CONSTITUTION: A thick wall portion 3 is formed at A (a boundary between a straight line and a circular arc of a notched portion having a longitudinal cross section with a circular arc shape and a straight line shape) where the bending moment becomes the largest in a wafer board holding portion 2 and its vicinity. Also, the length of the thick wall portion is set to about 1/4 to 1/2 of the overall length of the wafer board holding portion and located toward the tip portion from the vicinity of the portion A where the maximum bending moment occurs. As stated above, the portion where the bending moment of the wafer board holding portion 2 becomes the largest and its vicinity have a larger wall thickness compared to other portions, so that any breakage and bending of the wafer board holding portion 2 can be prevented and moreover deflection at the tip of the wafer board holding portion 2 can be decreased.

摘要： PURPOSE:To reduce wear and to decrease a specific resistance and contact resistance by setting the occupying ratio of graphite particle powder having 200-2000mum of grain size at the time of pressure molding to 900% or more. CONSTITUTION:Graphite particle powder 12 is dispersively disposed on a metal base material 11 made of metal, such as copper or silver on a metal graphite brush material 10. The powder 12 is formed by kneading natural or artificial graphite together with suitable binder (thermoplastic resin, thermosetting resin or tar pitch, etc.), drying the mixture and granulating it by a suitable granulating machine. The powder 12 has grain size distribution of 200-2000mum at this time. Thus, graphite particles can be rigidly bonded by a binding agent to suppress the removal of the particles and the wear. When the same amount of graphite is employed, its specific resistance and contact resistance can be reduced.
