摘要： A magnetoresistance sensor of this invention is designed to detect a magnetic field on the basis of a change in electric resistance of a magnetoresistance layer, and includes a substrate, the magnetoresistance layer, a magnetization stabilizing layer for stabilizing magnetization of the magnetoresistance layer, and an electrical conductive layer formed on the magnetoresistance layer or the magnetization stabilizing layer. The sensor is characterized in that the magnetoresistance layer and the magnetization stabilizing layer are stacked on each other such that the layers are magnetically coupled to each other at their two end regions with an exchange coupling force higher than that at the remaining region. With this arrangement, there is provided a magnetoresistance sensor having high sensitivity, which can apply a desired bias magnetic field to the MR layer while preventing the bias magnetic field from being disturbed by a magnetic field from a magnetic recording medium or the like.

摘要： A method of connecting waveguides and optical fibers includes the steps of forming the waveguides and a marker at the same time on a waveguide substrate when patterning the waveguides by a photolithography method, forming a clad layer on a region other than another region when the marker is formed so as to embed the waveguides, and forming a fitting pin groove at a position corresponding to a position of the marker. By using this fitting pin groove, a waveguide module and an optical fiber connector are connected so as to connect each of the waveguides and each of the optical fibers with each other. With this method, waveguides and optical fibers can be aligned and connected with each other easily and in a short period of time without employing an expensive aligning device.
