摘要： In a crystal holding apparatus, a corrugated portion between a seed crystal and a straight cylindrical portion of a monocrystal is held by holding portions of a lifting jig during a monocrystal growth process in which the seed crystal is brought into contact with material melt and is subsequently pulled while being rotated. In the crystal holding apparatus, an attachment member for establishing surface contact with the corrugated portion of the crystal is attached to the tip end of each holding portion of the lifting jig. Therefore, the monocrystal can be held reliably, so that the breaking and falling down of the monocrystal during the pulling operation can be prevented.

摘要： An apparatus for manufacturing a single crystal of silicon includes a crucible, a heater, electrodes, and a magnet. In addition to a plurality of heat generating portions and two main electrode portions, the heater has two or more auxiliary electrode portions. Two or more heater support members having an insulating property are further provided so as to support the heater through the auxiliary electrode portions. The number of heat generating portions which may be present between a heater support member and an electrode and between heater support members if adjacent to each other is equal to or less than 4. Each generating portion of the heater has a thickness of 25 mm or more. This structure makes it possible to produce a single crystal of silicon without causing breakage of a heater, even if a large electric current flows through the heater, even if a magnetic field of a high intensity is applied to a silicon melt in the crucible, and even if the heater has a large diameter.

摘要： A single crystal pulling apparatus which eliminates trouble caused by an isolation valve heated to a high temperature uses a heat insulation plate provided below the isolation valve. The heat insulation plate is operated synchronously with the opening or closing of the isolation valve. The heat insulation plate prevents hot gases from coming from the lower chamber from coming into direct contact with the isolation valve. The prevention of overheating of the isolation valve provides for smooth operation and growth of a good quality single crystal.

摘要： The present invention is intended to prevent the deformation of a cylindrical mouth portion of a preform when a blow pressure acts thereon in a diameter expanding direction during biaxial orientation blow molding. During biaxial orientation blow molding, sealing of the blow pressure is accomplished by means of a neck ring P1 circumferentially provided on a lower end of the circumferentially provided on a lower end of the circumferential surface of a cylindrical mouth portion P2 of a preform to thereby make the blow pressure act uniformly on the whole area of the cylindrical mouth portion P2, whereby the unreasonable deformation of the cylindrical mouth portion P2 due to the ununiform application of blow pressure thereto can totally be eliminated.
