There is provided a magnetic recording medium which exhibits superior lubricating properties and superior tape-transport properties as well as superior robustness even in a low-temperature environment. A magnetic layer containing a ferromagnetic metal is formed on a nonmagnetic support, and a protecting film is formed on the magnetic layer. A lubricant auxiliary coating composition comprising an aromatic alcohol is applied to the protecting film to form a lubricant auxiliary layer, and a lubricant coating composition comprising a compound represented by the formula (1) below is applied to the lubricant auxiliary layer to form a lubricant layer. R1CH(COOR2)CH2COOR3 (1) wherein R1 represents an aliphatic alkyl group, an aliphatic alkenyl group, or a hydrogen atom, and each of R2 and R3 independently represents a fluoroalkyl group, a fluoroalkenyl group, a fluoropolyether group, or a hydrogen atom.

A hard elastic body (10) having a longitudinally extending cavity (13) formed therein is provided mainly at a forefoot region (F) of a sole body. The cavity (13) is formed of a first curved surface (11) extending curvedly in a longitudinal direction and a second curved surface (12) disposed under the first curved surface (11) and extending curvedly in a longitudinal direction as well. A front and rear end of the second curved surface (12) is connected to a front and rear end of the first curved surface (11) respectively and an intermediate portion of the second curved surface (12) is spaced apart downwardly from an intermediate portion of the first curved surface (11). A path (PQ1) between the front and rear end of the first curved surface (11) is substantially equal to a path (PQ2) between the front and rear end of the second curved surface (12). When the first curved surface (11) is pressed downwardly, the sole body is deformed in such a way that a rear foot region (R) of the sole body is lifted upwardly.

The present invention relates to a tightening system for footwear, especially in athletic shoe, and is directed to improve the fittability, supportability and stability of the shoe. The athletic shoe of the present invention includes a supporting portion (Fs) for supporting the lateral side of a foot of a shoe wearer, a first fastening element of a loop shape that surrounds the periphery of the calcaneus (f2) of the foot, and a second fastening element of a loop shape that is provided integrally with the supporting portion (Fs). The supporting portion(Fs) extends from the position in the vicinity of the head of the metatarsus on the lateral side of the foot over the rear portion of the calcaneus of the foot to the medial side. The first fastening element, which is integrated with the terminus (Fs′) of the supporting portion (Fs), extends upwardly to the position corresponding to the navicular (f3) on the medial side, and passes over the instep above the navicular (f3), and returns to the lateral side of the foot and to the calcaneus lateral side of the supporting portion (Fs). The second fastening element extends from the medial side to the lateral side on the rear side of the base position of the proximal phalanx (f4) of the foot. The first and second fastening elements include medial side, lateral fastening elements (F1′), (F2′) that are provided on the lateral side, and joining parts that join the medial fastening elements to the corresponding lateral fastening elements.
摘要:
A disc device has a movable mechanism used for moving a carriage carrying a disc so that the carriage either projects from an apparatus or is inserted into the apparatus. The disc carried by the carriage is exposed for an operator to handle the disc when the carriage projects from the apparatus. The disc carried by the carriage is contained in the apparatus after the carriage has been inserted into the apparatus. A rotating unit rotates the disc carried by the carriage and an accessing unit accesses the disc carried by the carriage. The disc device is incorporated into the apparatus. A locking mechanism locks the carriage in the apparatus, and a releasing unit causes the locking mechanism to release locking of the carriage in the apparatus. The releasing unit causes the rotating unit to stop rotating of the disc and also causes the accessing unit to stop accessing the disc, prior to each time the releasing unit causes the locking mechanism to release locking of the carriage in the apparatus. The locking mechanism is contained in the carriage.
