摘要： PURPOSE:To provide the substrate for a magnetic disk by bringing ceramic power injected by using high-velocity air flow into collision against a blank plate surface for the magnetic disk, thereby forming ruggedness. CONSTITUTION:The ceramic powder introduced together with the high-velocity gas from an introducing port 1 is injected together with the high-velocity gas from a nozzle 2 and collides against the surface of the blank plate 3 for the magnetic disk placed at a prescribed distance. As a result, microbreakdown rises on the blank plate surface and eventually, the ruggedness is generated. The uniform ruggedness is formed over the entire surface of the blank plate surface if the blank plate surface is scanned with the nozzles at specified time intervals. The glass of the blank plate is silicate glass contg. SiO2. as an aggregate component. The ruggedness of the blank plate surface maintains the max. value Rmax and reference value of the roughness at adequate values by a measurement method complying with the requirements specified in JIS (Japanese Industrial Standards). The uniform ruggedness having no directivity within the plane is formed on the blank plate surface according to blast using the ceramic power having prescribed average grain sizes.

摘要： PURPOSE:To improve the wear resistance by forming the outermost layer of a protection film formed on the upper part of a magnetic recording film at the air side with an oxide film. CONSTITUTION:A protection film is provided on a magnetic recording film of a magnetic recording medium and the outermost layer of the protection film at the air side is made of an oxide film. The oxide film is preferably made of an oxide film represented by M.Nx.Oy (x, y depict an atomic ratio of N and O with respect to one atom of M) including at least one (expressed in M) selected out of a group of Ti, Zr, Hf, Sn, Ta and In and at least one (expressed in N) selected from B or Si, an oxide including especially Zr and B or Zr, Hf and B is preferred because the oxide is excellent in the wear resistance and the chemical stability. Thus, the magnetic recording medium having a protection film with excellent wear resistance is obtained.

摘要： PURPOSE:To improve slaking resistance and to provide unshaped refractories which can be stably applied by incorporating a binder contg. water glass and bentonite, hydration retarder and water retaining material into a calcareous refractory raw material which is an essential component. CONSTITUTION:For example, a spray coating material is prepd. by using a grain-sized adjusted CaO type refractory raw material, i.e., CaO type clinker as the essential component and incorporating the binder contg. the water glass and bentonite, the hydration retarder and the water retaining material such as fiber material therein. The bentonite powder to be used as the binder has the performance to easily adsorb and retain water when the water is added to the binder at the time of application, in addition to the role of the binder. The water glass cures at ordinary temp. as a binder and contributes to an improvement in strength and the adhesion to a wall surface. The hydration retarder is essentially required to prepare the spray coating material which can be stably used when the spray coating material is rested for several hours on account of a trouble, etc., at the time of the application. Boron oxide, oxalic acid powder, etc., are used for said material. The water retaining material prevents the evaporation of even the moisture necessary for curing of the binder by the abrupt evaporation of the moisture when the spray coating material is sprayed to >=150 deg.C wall surface, thereby obviating the degradation in the adhesive strength and the formation of the porous structure.

摘要： PURPOSE:To prevent cracking by separating a part to be sputtered and a part not to be sputtered with a spacing. CONSTITUTION:The part to be sputtered and the part not to be sputtered are separated and the spacing is provided therebetween, by which the distortion by the thermal stress at the time of sputtering is relieved and the generation of crack, dislodgment, etc., is prevented at the time of producing the sputtering target made of ceramics. Then, the long-term stable use of the large-sized sputtering target made of the ceramics is possible and the execution of the long-time operation of a large-sized device is possible.

摘要： PURPOSE:To increase resistance to scratching and resistance to wear without lowering low reflection characteristics by forming low reflective index films composed of a composite oxide as a main component containing one of Zr, Ri, Hf, Sn, Ta and In and at least one of Si and B as a part of a antireflection film. CONSTITUTION:A multilayer antireflection film is formed by laminating low refractive index films for the odd number layers counted from the air side and high refractive index films for the even number layers counted from the air side. The low refractive index film is formed as an antireflection film composed of a composite oxide as a main component containing at least one of Zr, Ti, Hf, Sn, Ta and In and at least one of Si (silicon) and B (boron). Thus, superior lubricating properties and superior performances of high resistance to scratching and resistance to wear can be provided without lowering low reflection characteristics, since the film is scratching-free and hardly get marks by friction.
