    摘要： A method of coating a magnetic disk wherein while rotating a disk held horizontal at a rotational frequency of 5-700 r.p.m., a magnetic coating composition is sprayed onto the upper and lower surfaces of the disk substantially simultaneously, to form coatings thereon, and the disk is further rotated at a raised rotational frequency, to adjust the thicknesses of the coatings. Further, in case of the rotation for adjusting the thicknesses of the coatings, a shield plate and a bottom plate are respectively disposed over and under the disk, or alternatively, shield plates are disposed over and under the disk, whereby the thicknesses of the coatings on both the surfaces of the disk are made uniform.

    摘要： In a device in which the rotation angle of the rotor is detected with a resolver, the rotation angle of the rotor with less error can be obtained while reducing burden of the operator. The measured angle value acquisition unit acquires the measured-rotation angle value of a motor shaft. The error calculation unit calculates the error included in each of measured-rotation angle values. The frequency component acquisition unit determines the phase and the amplitude of a frequency component of the error based on the errors. Thus, by using the error frequency component acquisition device, the phase and amplitude of the frequency component of the error included in the measured-rotation angle value can be automatically calculated and the correction with respect to the measure-rotation angle value can be performed using the acquired phase and amplitude. Therefore, the rotation angle of the rotor with less error can be obtained, while reducing the burden of the operator.

    摘要： A magnetic disk includes a non-magnetic substrate with a surface processed layer having fine irregularities formed at least on a main surface thereof, and at least thin film magnetic film and a protective film formed in that order on the non-magnetic substrate in such a manner that the fine irregularities are duplicated thereof. The surface of the surface processed layer of the non-magnetic substrate has protrusions whose surfaces are made flat and a configuration which exhibits a three-dimensional bearing curve in which the bearing ratio at a section taken at a depth from the top of the surface which corresponds to the portion of the top portion deformed by the head load during the contact start-stops drive is between 0.1% and 10%. The protrusions formed on the surface processed layer have a height ranging from several nm to several tens of nm. The bearing ratio is a value obtained at a depth of 5 to 10 nm from the top of the protrusions.

    摘要： The projector type vehicle headlamp includes a light source, a reflector including a reflection surface for reflecting light from the light source, and a condenser lens that irradiates reflected light from the reflection surface forwards. The reflection surface includes a plurality of segments, and is formed of a free-form surface obtained by deforming a reference ellipsoid of revolution. The light source is arranged between a first focal point of the reference ellipsoid of revolution and the condenser lens, closer to the first focal point than to the condenser lens. Segments forming one end and other end portions of a light distribution pattern includes a wide area-illuminating reflection surface that makes the one end and the other end portions substantially a rectangular shape, where the other end portion is opposite to the one end portion with respect to a center of the light distribution pattern.
