摘要： An objective lens is included in an optical pickup device that records and/or reproduces an information signal onto and/or from an optical recording medium. The objective lens has a numerical aperture of 0.82 or higher, has first and second surfaces that are both aspherical, and focuses a light beam onto the optical recording medium. The first and second surfaces have surface-to-surface eccentricity therebetween that causes an aberration, the aberration being correctable by tilting an optical axis of the objective lens relative to a central axis of the light beam incident on the objective lens. The aberration caused by the surface-to-surface eccentricity includes a third-order coma aberration. When the optical axis is tilted relative to the central axis of the incident light beam so that the third-order coma aberration becomes substantially 0 mλ rms, each of astigmatism, spherical aberration, and high-order coma aberration becomes 20 mλ rms or less.

摘要： A semiconductor device is provided with outer leads which show themselves in the bottom surface of the resin encapsulated body. This structure eliminates minute chipping and cracking near the resin which has been cut in the vicinity of the end of the outer lead. The semiconductor device is produced in such a way that a push-back-portion is previously arranged between leads of the lead frame and the push-back-portion is pushed down after molding. The resulting semiconductor device has outer leads such that there is no encapsulating resin between outer leads which show themselves in the bottom surface of the resin encapsulated body.
