  • Publication number: 20160318522
    Abstract: A vehicular system includes a master ECU, a first slave ECU, and a second slave ECU. The second slave ECU transmits a storing request to the master ECU on detection of a malfunction. The master ECU transmits a storing instruction for causing diagnostic information to be stored, on reception of the storing request. The first slave ECU generates diagnostic information on the first slave ECU, on reception of the storing instruction from the master ECU. The first slave ECU further stores the generated diagnostic information in a retention storage medium. The retention storage medium is configured to retain validity determination information in a condition where the first slave ECU is not supplied with electric power source.

  • Publication number: 20150198758
    Abstract: A light guide for use in an image reading apparatus. The light guide extends in a predetermined direction. The light guide comprises an emitting surface, through which light rays entering the light guide are emitted, and a reflecting surface configured to reflect the light rays to the emitting surface. A cross-sectional surface of the light guide, which is a sectional surface of the light guide along a plane orthogonal to the predetermined direction in which the light guide extends, has a shape including a combination of an ellipse and a parabola. The parabola on the cross-sectional surface of the light guide defines the reflecting surface. A focal point of the parabola is located on a first focal point of the ellipse that is closer to the reflecting surface.

  • Patent number: 8518283
    Abstract: The present invention relates to a plasma etching method in which a special area for detecting an end point needs not to be set and an equipment therefor. At an etching step of forming SF6 gas into plasma to etch an etching ground on a Si film, the step is configured by two steps of: a large-amount supply step of supplying a large amount of SF6 gas; and a small-amount supply step of supplying a small amount of SF6 gas. An end-point detecting processor 34 measures an emission intensity of Si or SiFx in the plasma at the small-amount supply step, and determines that an etching end point is reached when the measured emission intensity becomes equal to or less than a previously set reference value.
