Abstract: A semiconductor device according to an embodiment includes a semiconductor substrate, a cell region, and a termination region. The termination region surrounds the cell region and includes a plurality of first diffusion layers containing a first conductivity type impurity. In a cross-section of the termination region in a first direction perpendicular to the first face, at least one of the plurality of first diffusion layers includes a first region extending in the first direction from the first face toward a second face of the semiconductor substrate, and a second region extending in a second direction orthogonal to the first direction from the first region. The concentration of the first conductivity type impurity contained in the second region is lower than the concentration of the first conductivity type impurity contained in the first region.

Abstract: A semiconductor device includes a semiconductor part, first to fourth electrodes and a control electrode. The first and second electrodes are provided respectively on back and front surfaces of the semiconductor part. The third electrode is provided between the first and second electrodes, and provided in the semiconductor part with a first insulating film interposed. The fourth and control electrodes are provided between the second and third electrodes. The fourth and control electrodes extends into the semiconductor part from the front side and faces the third electrode with a second insulating film interposed. The fourth electrode is positioned between the semiconductor part and the control electrode. The first insulating film extends between the semiconductor part and the control electrode and between the semiconductor part and the fourth electrode. The fourth electrode faces the control electrode with a third insulating film interposed, and is electrically connected to the third electrode.

Abstract: A music support apparatus includes: a display unit; a bar width calculating unit configured to set display widths of the plurality of bars at a constant width; a bar width correcting unit configured to correct the display width of the bar to which the musical symbol for changing a performance tempo is designated; and a display information generating unit configured to generate display information to be displayed on the display unit from the plurality of bars of which display widths are calculated by the bar width calculating unit and the bar width correcting unit. The display unit is configured to display the display information and a performance position display portion for displaying a current performance position, and scroll either one of the display information and the performance position display portion at a constant tempo.

Abstract: With use of separated alloy powder (10) as a sintering material, it is possible to utilize characteristics of metals of different types (SUS steel and Cu, for example). Further, a boundary surface between regions constituted by different metals is at least partially alloyed. Thus, it is possible to enhance bonding strength between the regions, and possible to enhance strength of a sintered bearing.
