  • Patent number: 8179660
    Abstract: A highly reliable electronic device that prevents entry of a plating solution via an external electrode and entry of moisture of external environment inside thereof, and generates no soldering defects or solder popping defects which are caused by precipitation of a glass component on a surface of the external electrode. The electrode structure of the electronic device is formed of Cu-baked electrode layers primarily composed of Cu, Cu plating layers formed on the Cu-baked electrode layers and which are processed by a recrystallization treatment, and upper-side plating layers formed on the Cu plating layers. After the Cu plating layers are formed, a heat treatment is performed at a temperature in the range of a temperature at which the Cu plating layers are recrystallized to a temperature at which glass contained in a conductive paste is not softened, so that the Cu plating layers are recrystallized.

  • Patent number: 7733500
    Abstract: In a wavefront sensor, an optical wavefront to be measured is split into a first optical path and a second optical path. A wavefront W1 in the first optical path is transmitted through a first compensation member 7, and a wavefront W2 in the second optical path is transmitted through a second compensation member 8. Wavefronts W1 and W2 are mixed together by a semi-transparent mirror 6 with the wavefronts being displaced from each other by a shearing quantity S to form an interference fringe. An optical path difference that occurs between two wavefronts W1? and W2? which reach the interference measurement plane M in a state where the wavefronts are inclined due to the arrival direction of the optical wavefront to be measured is compensated when the wavefronts W1? and W2? are transmitted through the first and second optical path difference compensation members 7 and 8, respectively.
