    摘要： A disk drive 1 of the invention has through holes 27 formed in a turntable 4 in such a manner as to surround circumferentially a spindle 5, dislodgement preventive portions 28 provided to extend from a lower surface of a disk holding portion 9 towards a base portion 2 through the through holes 27, a hook locking portion 29 formed on an outer circumferential wall of a bearing holding portion 15 and hook portions 30 formed on distal end portions of the dislodgement preventive portions 28 which lie to a side of the base portion 2. In addition, the base portion 2 of the disk drive 1 of the invention includes a plurality of openings into which respective coils 20 are partially inserted and is configured such that an outer circumferential portion of a stator core 19a and the base portion 2 are spaced apart from each other at a predetermined interval.

    摘要： An electron energy spectrometer having an electron energy analyzer equipped with plural detectors including a reference detector. The energy of electrons impinging on the reference detector is stepped in increments. The value of these increments can be set at will. The spectrometer has improved detection accuracy and improved detection sensitivity. The spectrometer irradiates the surface of a sample with an electron beam. The energy of the electron beam is swept. The intensities of electrons ejected from the sample surface are analyzed. This instrument utilizes the multidetector scheme. Data about the intensities of the electrons is collected. Interpolation calculations are performed at each value of the energy according to the collected data.
