摘要： In preparing a purified fluorine-based solvent from a fluorine-based solution comprising a lubricant based on a fluororesin having an organic terminal group and a fluorocarbon-based solvent, impurities including ionic pollutants contained in the fluorine-based solution or the lubricant are selectively removed by an adsorption process. The preparation apparatus of a purified fluorine-based solvent is also disclosed.

摘要： A lubricant is provided that achieves a sufficiently small one-molecule-layer film thickness even when it has a high molecular weight, and has an increased reliability in a wide temperature range environment without losing the flying stability, by making the film thickness of a lubricant layer very small when it is used for the magnetic recording medium lubricant layer and/or head slider lubricant layer of a magnetic recording device. This lubricant comprises a fluorine-containing polymer, the lubricant having a relationship: Y

摘要： A device for positioning and clamping a board includes a plurality of clamping devices for clamping an edge portion of the board. Each clamping device includes positioning members for positioning the board with respect thereto, and a dragging device disposed between the clamping devices for dragging the board into contact with the positioning members. The dragging device is provided with a board clamping portion including a lower claw and an upper claw having rotating disks rotatably installed thereon for swivably clamping the board, and a reciprocating mechanism connected with the board clamping portion for reciprocating the board clamping portion. A board is first clamped by the dragging device and is dragged into contact with the positioning members of the clamping devices. The board is then pivoted and its attitude is straightened by further movement against the positioning members of the clamping devices, then the board is firmly clamped by the clamping devices and the clamping by the dragging device is released. Finally, the clamping devices are moved and a standard location is determined at a portion where the board traverses a sensor, thereby improving the space efficiency and avoiding lowering of positioning accuracy due to scattering of cutting chips.

摘要： An inspection head is used for an inspecting apparatus that inspects whether there is an abnormal projection on a disk surface having a first lubrication layer, and floats over the disk surface. The inspection head includes a floating surface covered with a second lubrication layer that is repellent to the first lubrication layer.
