摘要： A memory element and a memory device with improved controllability over resistance change by applied voltage are provided. The memory element includes a first electrode, a memory layer, and a second electrode in this order. The memory layer includes a resistance change layer provided on the first electrode side, and an ion source layer provided on the second electrode side and is higher in resistance value than the resistance change layer. A resistance value of the resistance change layer is changeable in response to a composition change by applied voltage to the first and second electrodes

摘要： An optical lens whose focal length is different on first and second planes perpendicular to each other is provided. The optical lens is configured such that a convex element, which is formed integrally with a substrate having a flat face, has a convex curved face that functions as an optical lens and is shaped such that the curvature on a first cross section and the curvature on a second cross section perpendicular to and intersecting with the first cross section are different from each other, whereby the focal lengths on the first and second cross sections are different from each other. A groove of a substantially elliptical shape or a substantially rectangular shape is formed along the boundary between the substrate and the convex element. The optical lens is used to produce a focus error signal or is incorporated into an optical pickup apparatus.

摘要： An optical head, able to reduce thermal stress generated in an optical lens mounted on a bobbin, having a bobbin formed with a center hole and an optical lens mounted on the bobbin via a thermal expansion adjustment member 40 formed with an opening. The optical lens has a substrate formed by an optical material different from the bobbin in coefficient of thermal expansion. The substrate has a convex part functioning as a convex lens and a flat part positioned around the convex part. The flat part is fixed to the thermal expansion adjustment member so that the convex part fits in the opening. The optical lens is placed so that a center axis of the convex part or an extension thereof passes through the center hole of the bobbin and the center axis of the convex part coincides with a center hole of the bobbin.

摘要： An optical device used for converging a light beam on a signal recording surface of an optical disc includes an optical lens for converging the light beam on a signal recording surface of the optical disc and a light barrier portion provided on a surface of the optical lens facing the optical disc. The light barrier portion includes a light transmitting aperture through which is transmitted the light beam converged by the optical lens. The light beam illuminated on the optical disc has its diameter controlled by this light transmitting aperture. The light radiated by a light source so as to be incident to the optical device is converged by the optical lens. The light converged by the optical lens is transmitted through the light transmitting aperture and illuminated on the signal recording surface of the optical disc. The diameter of the light beam illuminated on the signal recording surface of the optical disc is controlled by the light transmitting aperture, and thus the numerical aperture NA of the optical device is determined.
