Publication number: 20110143460Abstract: An embodiment of the invention provides a method of manufacturing a magnetoresistance element with an MR ratio higher than that of the related art. A method of manufacturing a magnetoresistance element includes a step of forming a magnetization fixed layer, a magnetization free layer, and a tunnel barrier layer provided between the magnetization fixed layer and the magnetization free layer on a substrate. In the method, the tunnel barrier layer is formed by arranging a target that has a diameter smaller than that of the substrate, contains a magnesium oxide sintered body, and has a relative density 90% or more so as to be inclined with respect to a surface to be deposited of the substrate, and forming a magnesium oxide layer using a sputtering method while rotating the substrate.Type: ApplicationFiled: August 31, 2009Publication date: June 16, 2011Applicant: CANON ANELVA CORPORATIONInventors: Koji Tsunekawa, Yoshinori Nagamine, Shinji Yamagata

Publication number: 20100309679Abstract: A projector headlight for a low beam can include a first and second lighting unit. Each of the first and second lighting units can include an LED light source, an ellipsoidal reflector, a projector lens and a shade. Light emitted from the LED light source can form a light distribution pattern from the projector lens via the ellipsoidal reflector by shielding an upwards portion of the light with the shade. The shade of the second lighting unit may be configured so as not to project light on a specific point under a cut-off line on an oncoming lane using a convex portion thereon. Therefore, the first lighting unit can project light with a maximum light intensity at the specific point so as to overlap the light distribution pattern formed by the second lighting unit. Thus, the projector headlight can perform a favorable light distribution pattern that can conform to a light distribution standard for headlights.Type: ApplicationFiled: June 4, 2010Publication date: December 9, 2010Inventors: Shinji Yamagata, Takashi Akutagawa
