摘要： A dynamic pressure bearing is defined in a first gap between a shaft portion and a sleeve portion. An upper seal portion extending upward and a lower seal portion extending downward are arranged radially outward of the dynamic pressure bearing. Each of the upper seal portion and the lower seal portion includes a surface including a lubricating oil located therein. The upper seal portion and the lower seal portion are arranged in communication with each other through a communicating hole defined in the sleeve portion. The communicating hole and a space ranging from the upper seal portion to the lower seal portion through the first gap are filled with the lubricating oil. The axial distance between the surfaces of the lubricating oil in the upper seal portion and the lower seal portion is arranged to be shorter than the axial distance between an upper end and a lower end of the dynamic pressure bearing.

摘要： In a motor, an annular radially extending gap is defined between an outer annular surface and a lower surface of an annular cover portion. The radially extending gap has an axial width smaller than a maximum width of an upper seal portion defined between an outer circumferential surface of an upper thrust portion and an inner circumferential surface of a tubular portion. An annular axially extending gap is defined between an inner cylindrical surface and a radially inner edge of the annular cover portion. The axially extending gap has a radial width smaller than the maximum width of the upper seal portion.

摘要： A spindle motor includes a stationary portion and a rotating portion including a seal defining portion. The stationary portion includes a shaft portion, an annular member fixed to an upper portion of the shaft portion in, for example, a tight-fitting condition, and a cap member. A radially inner end portion of the cap member is fixed to each of the shaft portion and the annular member preferably through, for example, an adhesive. An upper seal portion, in which a surface of a lubricating oil is arranged, is defined in an upper seal gap defined between an outer circumferential surface of the annular member and an inner circumferential surface of the seal defining portion. The cap member is arranged to cover an upper side of the upper seal portion.

摘要： A microscope control device includes an offset processing unit that corrects phase contrast information regarding a phase contrast between corresponding phase contrast images, which is generated based on a set of the phase contrast images of a sample which are captured by a microscope, based on offset information of phase contrasts caused by optical distortions unique to the microscope, and a defocus amount calculation unit that calculates a defocus amount of the sample on the basis of the phase contrast information after offset correction.
