US Classification:

117208

Abstract:

A hopper is sized and shaped for reception in a crystal pulling apparatus for use in charging semiconductor source material to a crucible of the crystal pulling apparatus. The crystal pulling apparatus includes a pulling chamber, a growth chamber, an isolation valve operable to seal the growth chamber from the pulling chamber, and a crucible in the growth chamber. The hopper includes a bin constructed for containing a quantity of semiconductor source material. The bin has an opening in its bottom for delivery of the semiconductor source material from the bin to the crucible. A stopper constructed for closing the opening to prohibit passage of semiconductor source material from the bin is moved by a stopper actuating mechanism between a closed position and an open position. A connector attached to the hopper is constructed for temporarily mounting the hopper in the crystal pulling apparatus.

Abstract:

An injection molding process for molding an assembly of a frontcurve molds in a plurality of unitary solid piece of polymer in which plurality of frontcurve molds are arranged symmetrically around a single center polymer injection gate. In this arrangement the molten polymer flows radially outwardly therefrom uniformly in all directions to the four frontcurves to form one common molded piece of polymer. In a compression injection molding process, the pressure on the molten polymer is maintained relatively constant, and the mold is mechanically collapsed during the molding operation. The present invention molds an assembly of frontcurve molds in a manner in which there is a significant reduction of residual stress locked into the resultant assembly of frontcurve molds. This results in a significant reduction in warpage and shrinkage of each frontcurve mold, which is not optically stressed, and results in a subsequent casting of an ophthalmic lens which is not optically stressed. Moreover, the assembly of frontcurve molds can function as its own support pallet for product placement and alignment purposes during subsequent production operations.
