摘要:
The present invention provides a target substance transfer method, a crystal production method, a composition production method, and a target substance transfer device, which allow the concentration of a target substance to be increased easily and effectively. The target substance transfer method is a method for transferring a target substance 103 from a first phase 101 that is a liquid or solid phase containing the target substance 103 to a second phase 102 including: a phase approximation step of bringing the first phase 101 and the second phase 102 into close proximity; and a bubble collapse step of forming bubbles in the vicinity of a boundary between the first phase 101 and the second phase 102 and then causing the bubbles to collapse.

摘要:
Provided are novel data storage devices, such as hard disk apparatuses. The devices include a clean chamber accommodating a component formed from a free cutting stainless steel. The free cutting stainless steel has a sulfur (S) content of not less than 0.25 percent by mass and a manganese-to-sulfur content ratio (Mn/S) of not greater than 1.8. The free cutting stainless steel has been subjected to: (1) an acid cleaning; (2) to a passivation treatment; (3) to a degreasing treatment and to a subsequent rust-removing, descaling chemical treatment; or (5) to a degreasing treatment and to a subsequent chromate treatment.
