摘要： A silica glass crucible used for pulling up a silicon single crystal and made from natural silica a raw material is provided with a region within a certain range from the center of a bottom section of the crucible and up to 0.5 mm deep from an inner surface and which substantially does not include gas bubbles, wherein an average value of a concentration of Al included in a region within the certain range from the center of the bottom section of the crucible and up to 0.5 mm deep from the inner surface is 30 ppm or more and 150 ppm or less. In the case where the inner layer of the crucible bottom section is formed in this way, dents in the inner surface are prevented and the generation of gas bubbles is reduced.

摘要： To provide a suction recovery method of an ink jet printing apparatus by which ink can be securely filled to an ink flow path and a nozzle while minimizing an amount of ink discharge during a suction recovery to prevent an adverse effect such as invited bubbles. The suction recovery method firstly performs the first suction step for generating a negative pressure for sucking a filter section for separating bubbles from the filter section. Thereafter, the second suction step is performed to generate a negative pressure for sucking an ink in the ink flow path and a large nozzle. Thereafter, the third suction step is performed to suck ink from a small nozzle.
