A method for manufacturing a glass substrate for magnetic disk is provided in which a glass is kept from being fused to a mold during press forming and shape processing to achieve a good circularity is efficiently performed. The method includes: a forming process of forming a disk-shaped glass blank by direct-pressing a molten glass by a pair of dies; and a shape processing process of performing at least one of inner hole formation and outer shape formation for forming a disk-shaped glass substrate by forming a cutting line on the principal face of the glass blank, followed by growing the cutting line to perform cutting. In the forming process, press forming is performed while the temperature of the pair of dies, over a period of time until a molten glass is separated from the die after coming into contact with the die, is set at a temperature lower than a glass transition point (Tg) and a mold release material is not attached to the surfaces of the pair of dies.

A rotary compressor includes: a driving element which is provided inside a sealed container; and a rotary compression element which is provided inside the sealed container so as to be located below the driving element. A refrigerant discharge pipe is inserted from a side surface of the sealed container above the driving element into the sealed container, and is opened in the horizontal direction. A refrigerant compressed by the rotary compression element is discharged from a discharge hole into the sealed container, and is discharged from the refrigerant discharge pipe to the outside of the sealed container. The position of the discharge hole is set to a position below an area A1 on the opposite side of the opening direction of the refrigerant discharge pipe from a line L1 passing an opening surface of the refrigerant discharge pipe and perpendicular to the opening direction of the refrigerant discharge pipe.
