    • An exhaust manifold includes: a double collecting pipe having an inner pipe, including a collecting pipe portion and branch pipe portions, and an outer pipe, covering the collecting and branch pipe portions and thicker than the inner pipe; and an inner pipe retainer having semi-circular portions and a connecting portion, and thicker than the inner pipe and thinner than the outer pipe. The inner pipe retainer connects the inner and outer pipes with a gap therebetween. Exhaust gas from exhaust ports of a set of cylinders is introduced into the collecting pipe portion through the branch pipe portions. The total spot-welded area of the outer peripheral portions of the branch pipe portions and the inner peripheral portions of the semi-circular portions is larger than that of the inner peripheral portion of the outer pipe and the outer peripheral portions of the semi-circular portions.

    • A ring groove for a two-piece oil ring of a piston is provided that has ring body equipped with a coil expander, wherein the ring body has an upper outer surface and a lower outer surface, both orthogonal to the axial direction of the piston. The ring groove also has an upper inner surface and a lower inner surface, both orthogonal to the axial direction of the piston; a radially inward-most, bottom surface connecting the upper and lower inner surfaces; and oil drain holes, each having an opening thereof located on the bottom surface. The ring groove has an axial width slightly greater than the width of the two-piece oil ring. The ring groove has a radially inward ends of the upper and lower surfaces of the ring groove, respectively, located radially inwardly apart by a first predetermined distance from the radially inward ends of the upper and lower outer surfaces of the ring body when the oil ring is mounted within the ring groove so that the outer circumferential surface of the ring body is in contact with the inner circumferential surface of a cylinder which is engaged with the piston.

    • A video switcher includes: a video signal switching device for switching a video signal to be transmitted to a video display unit from a first video signal supplied from a first video input unit into a second video signal supplied from a second video input unit; and a synchronization signal switching device for switching a synchronization signal to be transmitted to the video display unit from a first synchronization signal supplied from the first video input unit into a second synchronization signal supplied from the second video input unit. The synchronization signal switching device starts transmission of the second synchronization signal to the video display unit after stops transmission of the first synchronization signal to the video display unit. The video signal switching device starts transmission of the second video signal to the video display unit, after stop of transmission of the first video signal to the video display unit and start of transmission of the second synchronization signal to the video display unit.
    • 视频切换器包括:视频信号切换装置,用于将从第一视频输入单元提供的第一视频信号转换为视频显示单元的视频信号切换成从第二视频输入单元提供的第二视频信号; 以及同步信号切换装置,用于从从第一视频输入单元提供的第一同步信号切换到要发送到视频显示单元的同步信号到从第二视频输入单元提供的第二同步信号。 同步信号切换装置在停止向视频显示单元发送第一同步信号之后开始向视频显示单元发送第二同步信号。 视频信号切换装置在停止向视频显示单元发送第一视频信号并开始向视频显示单元发送第二同步信号之后,开始向视频显示单元发送第二视频信号。
