摘要： PURPOSE:To satisfactorily disperse magnetic particles and to improve magnetic characteristics and surface characteristics by incorporating a specific aluminum coupling agent into a magnetic layer. CONSTITUTION:This magnetic recording medium contains the aluminum coupling agent expressed by the formula at 0.1-10.0% ratio to the magnetic powder in a magnetic coating compd. coated on a nonmagnetic substrate. (In the formula, R is a hydrocarbon group.) The aluminum coupling agent reacts powerfully with the hydroxyl group on the powder surface upon contact with the magnetic powder and to aluminum atoms bond securely through oxygen atoms onto the surface of the magnetic powder. This type of the aluminum coupling agent, therefore, forms a film by sticking securely to the particle surface of the magnetic powder when said agent is incorporated into the magnetic layer. The dispersibility of the magnetic powder is thus extremely improved, by which the magnetic characteristics and surface smoothness are improved. The mixing ratio of the coupling agent is preferably in a 0.1-10.0%, more preferably 1.0-3.0% range.

摘要： PURPOSE:To improve runnability, wear resistance and durability by depositing perfluorodicarboxylate as a lubricating agent on a thin ferromagnetic metallic film which is a magnetic layer. CONSTITUTION:The thin ferromagnetic metallic film is formed on a nonmagnetic base and the lubricating agent contg. the perfluorodicarboxylate is deposited on the thin ferromagnetic metallic film. The perfluorodicarboxylate to be used as the lubricating agent includes monoester of perfluorodicarboxylic acid, diester of perfluorodicarboxylic acid and perfluoroalkylester of perfluorodicarboxylic acid which are respectively expressed by the formula I. In the formula I, R denotes a hydrocarbon group of 1-25c, and n>=2. The coefft. of dynamic friction is thereby decreased under any temp. conditions and the magnetic recording medium having excellent running stability and wear resistance is obtd.

摘要： PURPOSE: To obtain a magnetic recording medium having a protective layer which has high adhesive strength to a thin magnetic film and has excellent durability and running property by forming the thin ferromagnetic material film layer, a layer formed by subjecting the surface of said thin film to an oxidation treatment and a coupling agent treatment layer as the protective layer on a non-magnetic substrate.
CONSTITUTION: The thin ferromagnetic metallic film is formed on the non- magnetic substrate consisting of a polyester film, etc. by orienting the axis of easy magnetization of the thin magnetic film of preferably a Co-Cr alloy consisting essentially of Co in the direction perpendicular to or parallel with the film plane. The surface part of the magnetic film is then oxidized to form the oxide layer and thereafter an org. Si coupling agent, org. Ti coupling agent or org. Zr coupling agent is coated directly or in the form of a soln. of alcohol, freon, etc. on said layer to form the surface protective layer. The exfoliation of the protective layer from the magnetic film is thus obviated as the oxide layer is intervened. The thin film type magnetic recording medium having the excellent lubricity and durability is obtd.

摘要： PROBLEM TO BE SOLVED: To make a lubricant for a liquid dynamic pressure bearing device have a sufficiently low crystallization starting temperature of a solid phase without being lost by evaporation even by use over a long period of time and usable in a motor etc. having a wide service environmental temperature range. SOLUTION: The lubricant comprises two kinds of ionic liquids in which cations or anions are common and has ≤-40°C crystallization starting temperature of the solid phase and ≤25 mPa viscosity at room temperature. One of the ionic liquids is in a liquid form having ≤30 mPa viscosity at room temperature and the freezing point is ≤-40°C freezing point. The other ionic liquid is in the liquid form having ≤30 mPa viscosity at room temperature and the freezing point is ≥-40°C. COPYRIGHT: (C)2008,JPO&INPIT
