    摘要： An optical pickup has a laser light source, beam splitter, collimator lens, reflection mirror, objective lens and photo detector are mounted in a case. An objective lens actuator includes a magnetic member and magnet. The optical pickup may become contaminated by uncured adhesive remaining at the edges of the adhesive surfaces of the magnet and the magnetic member that is transferred to the optical pickup via finger cots or tweezers, etc. In an adhesion step between the magnet and the magnetic member, in which part of a groove near to the center of the surface has a small depth and part of the groove near to the outer circumference of the surface has a large depth, an adhesive is drawn toward the center of the surface of the magnetic member by a capillary phenomenon and is prevented from spreading along the outer edge of the surface.

    摘要： The present invention provides a semiconductor memory device that includes: a fuse circuit having multiple fuse elements; and a fuse selection circuit connected to an internal address signal line that receives an address signal externally inputted. The fuse circuit is connected to the fuse selection circuit to receive an output from the fuse selection circuit, is supplied with an externally inputted trigger signal that permits nonvolatile recording of the fuse elements, and, in response to the output and the trigger signal, records the fuse element corresponding to the internal address signal line among the plurality of fuse elements while recording at least one of the plurality of fuse elements other than the fuse element thus recorded.
