    摘要： A magnetoresistive film is formed on the surface of a lower electrode layer in a method of making a current-perpendicular-to-the-plane structure magnetoresistive element. The magnetoresistive film includes a lower portion and an upper portion overlaid on the lower portion. The lower portion includes at least a pinned magnetic layer. The upper portion includes at least a free magnetic layer. A pair of domain control magnetic layers is formed to sandwich the magnetoresistive film. An insulator film is formed to cover over the domain control magnetic layers. The upper portion is subjected to an etching process. The domain control magnetic layers are reliably prevented from being removed during the etching process. Accordingly, the domain control magnetic layers are allowed to reliably sandwich the upper portion of the magnetoresistive film in the aforementioned manner.

The concave mirror is configured so that its lateral focal length contributing to lateral enlargement of a displayed image is shorter than its longitudinal focal length contributing to longitudinal enlargement of the displayed image. The reflection-type hologram is configured so that its longitudinal focal length contributing to longitudinal enlargement of the displayed image is shorter than its lateral focal length contributing to lateral enlargement of the displayed image.

    摘要： An apparatus for deflecting light of the present invention comprises: (a) at least one pair of transference electrodes arranged facing one another; (b) a drive circuit which applies a voltage among the transference electrodes; and (c) a liquid crystal which is inserted among the transference electrodes, and whose parallel stripes that function as a diffraction grating when the voltage is applied among the transference electrodes are produced at a pitch corresponding to the applied voltage. The light can be scanned if a diffracted light by the apparatus for deflecting light is converted into a scanning light and a voltage value is changed temporally to apply the voltage among the transference electrodes. In a device for reading information, the scanning light is reflected in a bar code and the reflected light is detected by an apparatus for detecting light. In a device for stereoscopic display of the present invention, the apparatus for deflecting light is used as beam deflection means for deflecting the light beamed from a picture element which organizes the pictures of the picture display means.
