Abstract: In a power converter, cooling of the power converter is extremely important for improving a power conversion performance. Specifically, a DC smoothing capacitor module stored in a housing of the power converter is heat-sensitive, and in order to secure the performance, efficient cooling of the capacitor module is required. In addition, reducing the heat entering from the outside as much as possible is required. A conductor panel of the capacitor module and the housing are connected via a cooling panel, an AC connection bus bar and the housing is connected by the cooling panel to release heat from the capacitor module and the AC connection bus bar to the housing via the cooling panel.

Abstract: The invention is directed to an improvement of performance for disposable absorbent articles to prevent a leakage of body discharges. A disposable absorbent article comprising: an absorbent body having an average width of from about 5 mm to about 30 mm. The first resilient material is disposed between the body facing surface and the garment facing surface of the absorbent article; and a first resilient material disposed between the body facing surface and the absorbent body in a circumferential manner such that at least a part of the body facing surface of the absorbent article forms a raised circumferential bank in the central region and a concave portion surrounded by the raised circumferential bank. The first resilient material is selected from the group consisting of a polymeric foam material, a fibrous material, an elastic material, a formed film material, an absorbent gelling material, and a mixture thereof.

Abstract: A stencil is made by thermally forming perforations arranged in both a main scanning direction and a sub-scanning direction in a thermoplastic resin film of heat-sensitive stencil material by the use of a heat source which is heated through supply of energy. Supply of energy to the heat source is cut so that the quotient obtained by dividing a maximum diameter of a perforation at the time at which supply of energy to the heat source is cut by the energizing time is not smaller than 0.015 m/s and not larger than 0.23 m/s.

Abstract: A stencil is made by thermally forming perforations arranged in both a main scanning direction and a sub-scanning direction in a thermoplastic resin film of heat-sensitive stencil material by the use of a heat source which is heated through supply of energy. Supply of energy to the heat source is cut when a time interval not shorter than 50% and not longer than 100% of an estimated perforating time lapses from the time at which supply of energy to the heat source is started. The estimated perforating time is a time interval expected to be necessary for a perforation to be produced by the heat of the heat source and to be enlarged to a desired size as a final size as measured from the time at which supply of energy to the heat source is started.
