    摘要: An electric power converter is provided with: a power semiconductor module, which has a power semiconductor element that converts a direct current into an alternating current; a capacitor module, which has a capacitor element that smooths the direct current; and a cooling body, which cools the power semiconductor module and the capacitor module. The capacitor module has a case, which has an approximately rectangular shape, has an opening formed in one surface, and has a space for housing the capacitor element; and a DC conductor for electrically connecting the power semiconductor element and the capacitor element to each other. The cooling body is formed to face the bottom surface on the inner wall of the case, and both the side surfaces of the case, the side surfaces facing each other. Between the capacitor element and the inner wall surfaces of the case, the direct current conductor is formed along the bottom surface and both the side surfaces of the case.

    摘要: A method for laying a sheet over the lower surface of a base material disposed in a generally horizontal position. According to the method, the base material is supported at the lower surface thereof by a first support means, and the sheet is placed immediately below and in facing relation to the lower surface of the base material and then supported at the lower surface thereof by a second support means. The sheet and the base material are made to be in contact with each other over partial surfaces thereof. Subsequently, the first support means is moved away from the base material and the sheet and the base material are placed together on a rigid horizontal surface so that the sheet is laid substantially over the entire lower surface of the base material.
