Dy 3 (Ga 1 − x Al x) 5 O 12 pseudo-binary single crystals were grown by the Czochralski method. The influence of Al 3+ ions on the spiral bending was investigated. Effective suppression of the spiral symptoms takes place at x = 0.4. In the case of x = 0−0.2 the spiral symptoms were observed in the tail part of crystals. In the case of x = 0.6 there are no spiral symptoms.

such as mercury (36.38 Pa at 100 °C), the liquid gallium alloy can be used in the high vacuum condition. Consequently, the liquid gallium alloy is the best fluid lubricant for the hydrodynamic bearing in X-ray tube. But, the spiral grooved bearing is adopted, and only the weight of the rotating body is considered as the load carrying capacity.
