    • An apparatus for pressing a glass article is disclosed including a frame (12), a mold (14) mounted on the frame having first and second mold halves (44) defining a cavity (62), a device (82) for opening and closing the mold halves, a plunger (16) movably mounted on the frame adjacent the cavity for pressing the glass gob into the cavity to form the glass article and a device (160) for moving the plunger. An alternative embodiment is a machine for pressing a plurality of glass articles at a high cavity rate including at least two apparatus mounted on a device for moving the apparatus. The method of the present invention includes the steps of: (a) rotating a carriage to which at least two apparatus are attached; (b) actuating the device to close the mold; (c) placing the glass gob adjacent the cavity; (d) actuating the device to move the plunger to press the glass gob into the cavity to form the glass article; (e) withdrawing the plunger; (f) actuating the device to open the mold a predetermined distance to cool the mold; and (g) actuating the device to open the mold to remove the glass article from the cavity.

    • The present invention provides a single-crystal silicon pulling silica container comprising: a transparent layer made of transparent silica glass in an inner side of the silica container, and an opaque layer made of opaque silica glass containing gaseous bubbles in an outer side of the silica container, wherein the transparent layer is constituted of a high-OH group layer that is placed in an inner surface side of the silica container and contains the OH group at a concentration of 200 to 2000 ppm by mass and a low-OH group layer that has the OH group concentration lower than that of the high-OH group layer, and Ba is applied to the inner surface of the high-OH group layer at a concentration of 25 to 1000 µg/cm 2 . As a result, in a case where the silica container is used for pulling single-crystal silicon, there can be provided the silica container that can greatly improve etching resistance (corrosion resistance) of the container inner surface to silicon melt when the entire inner surface made of transparent silica glass of the container is finely crystallized (turned to glass ceramics) in a short time after start of using the container and also provided a method for producing such a silica container.
    • 本发明提供一种单晶硅提拉用二氧化硅容器,其包括:在二氧化硅容器的内侧面由透明的石英玻璃构成的透明层,并制成不透明的石英玻璃含有气泡在于二氧化硅的外侧的不透明层 容器,worin透明层由高OH层的并通过质谱在二氧化硅容器的面内并排放置,并包含OH基团在200的浓度至2000ppm和低OH基团层做 具有OH基团浓度比该高-OH基层低,和Ba是在25至1000g / cm 2的浓度施加到高OH层的内表面。 其结果是,在将二氧化硅容器用于提拉单晶硅的情况下,可以提供的二氧化硅容器确实可以大大改善蚀刻到硅熔体中的容器内表面的电阻(耐腐蚀性)当整个内表面 使用容器的开始之后进行,在短时间内将容器微细结晶的透明石英玻璃(转向玻璃陶瓷)的并由此的制造寻求的二氧化硅容器提供了一种方法。
