    摘要： There is provided an apparatus as well as a method for polishing, observing, and additionally polishing a sample in a vacuum with a charged particle beam apparatus furnished with no other apparatus.The charged particle beam apparatus has a vacuum chamber equipped with a liquid bath containing an ion liquid and a supersonic vibration means. With the ion liquid kept in contact with a polishing target area of the sample, supersonic vibration is propagated in the ion liquid to polish the sample.Because the charged particle beam apparatus permits polishing, observation, and additional polishing of the sample in a vacuum without being furnished with any additional apparatus, throughput is improved and the effects of the atmosphere on the sample are prevented.

    摘要： There is provided an optical disc drive for recordation/reproduction for three types of optical discs by selectively using one of three types of light beams. The optical disc drive comprises an objective lens. The objective lens has a step structure which gives an optical path length difference to an incident beam at each step. When the third laser beam passes through the objective lens, the objective lens produces normal diffraction order light converging to a recording surface of the third optical disc and undesired diffraction order light converging to a point deviating from the recording surface of the third optical disc. A distance from a point to which the normal diffraction order light converges to a point to which the undesired diffraction order light converges is larger than or equal to twice a pull-in range of a focus error signal obtained when the third optical disc is used.

    摘要： There is provided an objective lens used for three types of optical discs including by selectively using one of three types of light beams. At least one of surfaces of the objective lens is provided with a first region converging the third light beam on a recoding surface of the third optical disc. The first region has a step structure configured to have concentric refractive surface zones and to give an optical path length difference to an incident beam at each step formed between adjacent refractive surface zones. The step structure is configured such that the optical path length difference given by each step is substantially equal to an odd multiple of a wavelength of a first light beam, and a value of differentiation of an optical path difference function defining the step structure crosses zero in a height ranging from 30% to 70% of an effective diameter of the first region.
