    摘要: An object of the present invention is to provide a cover that is made less prone to be removed even if receiving an impact due to falling or the like, and an operation for removing the cover is made easy. An engaging piece position regulating member made of a viscoelastic body such as an urethane-based resin is provided on a left side of an elastically-deformable engaging piece of a cover, which allows an engaging projection of the engaging piece to leave from an engaging hole when the cover is removed from a device casing by manual operation and inhibits the engaging projection of the engaging piece from leaving from the engaging hole when a rate of deformation larger than a rate of deformation by manual operation is provided to the engaging piece by an impact due to falling or the like.

    摘要: In a semiconductor substrate of a first conductivity type, first to third drain offset regions of a second conductivity type are formed in that order in a bottom up manner. A body region of the first conductivity type is formed partly in the second drain offset region and partly in the third drain offset region. The second drain offset region has a lower impurity concentration than the first and third drain offset regions. A curvature portion of the body region is located in the second drain offset region.
