Abstract: A specimen preprocessing/transport apparatus includes a test tube transport path on which test tubes filled with specimens are held in test tube holders and transported, a rack transport path on which sample cups are held in a sample cup rack and the rack is transported, a filled-tube loading section which loads the test tubes into the test tube transport path, a rack loading section which loads the sample cup rack into the rack transport path, an aliquoting/dispensing device which is located in the middle of the test tube transport path and configured to simultaneously aliquot the specimens in the test tubes, and simultaneously dispense the sample cups on the rack transport path, and an analyzer which is located on the downstream side of the rack transport path and configured to receive the sample cup rack stored with the specimens and analyze the specimens.

Abstract: A magnetic recording disk has a high-adhesion lubricant layer that permits an operation at an extremely low level of flying height of 12 nm or less without troubles and which is capable of preventing the migration at a high-speed rotation, and comprises a substrate, a magnetic layer formed on the substrate, a protective layer formed on the magnetic layer and a lubricant layer formed on the protective layer, the lubricant layer containing a compound (A) of the general formula (I), wherein each of p and q is an integer of 1 or more, and a compound (B) having a perfluoropolyether main chain having two end moieties each of which contains a carbon atom or an oxygen atom to which a hydroxyl-containing hydrocarbon group that optionally contains ether bond(s) is bonded, and a process for the manufacture thereof is provided.
