摘要： A method for simply and efficiently separating substances by utilizing a specific flow behavior in a non-turbulent flow, i.e. a laminar flow, in a micro-channel is disclosed. A mixed solution containing at least two kinds of solute molecules which are different from each other in molecular weight and/or molecular sharp, or at least two kinds of solutions containing their respective solute molecules are flowed into a micro-channel to form a non-turbulent flow. A physical action is given to each molecule by changing the state of flow, thereby causing different behaviors among the different solute molecules. By utilizing this behavior difference, molecules of a specific kind are gathered in a specific region in the channel for separation.

摘要： Embodiments of the invention prevent a decrease in magnetization or demagnetization from occurring to recording magnetization regardless of a direction in which a stray field is applied. In one embodiment, an apparatus for data storage system comprises a head having a magnetic field shield in the vicinity of a main pole, and a cover of the device, using a constituent material with a magnetic field shielding effect, across the cover, or at part thereof. When a stray field in a direction perpendicular to a recording medium is applied, the effect of the magnetic field is alleviated by the magnetic field shield installed in the vicinity of the main pole. In such a case, it need only be sufficient to form the magnetic field shield in a shape optimum for removing the stray field in the perpendicular direction only. When a stray field in a direction horizontal in relation to the recording medium is applied, the magnetic field acting on the recording medium is removed by the cover of the device comprising a magnetic component.
