Abstract: An electronic device includes a base material, a first metal film disposed on the base material and containing nitrogen and chromium, and a second metal film disposed on the first metal film and containing gold. In the first metal film, the number of nitrogen atoms may be between 20% to 100% of the number of chromium atoms. Further, the distribution of nitrogen atoms in the first metal film is larger in a third region sandwiched between a first region on the base material side of the first metal film and a second region on the second metal film side than in the first region and in the second region.

Abstract: Present invention relates to a high performance rotating electrical machine which aims at downsizing, and challenges inevitable technical problems such as deterioration of efficiency ? caused by copper loss and temperature rise inside the rotating electrical machine due to heat generation induced by eddy current generated in magnetic body.

Abstract: A power transmission member is disclosed. The power transmission member allows a planetary gear mechanism to be reduced in volume while sufficient strength is guaranteed. A planetary gear holding part, a rotating shaft part, and a sun gear holding part constituting a power transmission member are formed integrally. The rotating shaft part is substantially cylindrical, and a planetary gear can be passed through the interior of the rotating shaft part and turnably mounted on the planetary gear holding part. An open window is formed in the planetary gear holding part, and a toothed part of the planetary gear is configured to mesh with a bearing-equipped outer gear through the open window.

Abstract: An autofocus camera is provided which restrains and corrects any tilt that may occur in the optical axis direction without the need of providing any additional new sensors for that purpose. The autofocus camera includes an image sensor for receiving light from an object and converting the light into corresponding electrical signals, a lens driving device having a lens for focusing the light from the object upon said image sensor, and a control portion for causing said lens driving device to adjust any tilt that may occur in the optical axis in response to the electrical signals received from said image sensor. The control portion is operated to cause the lens driving device to adjust any tilts of the optical axis with respect to the image sensor in the orthogonal directions with each other, so that the resolution signals at the predetermined positions of said image sensor can be maximized.
