20100182747 | SEMICONDUCTOR ELEMENT COOLING STRUCTURE - A semiconductor element cooling structure includes a plurality of semiconductor elements, and electrode structure, which has cooling medium channels therein and is electrically connected to the plurality of semiconductor elements. The electrode structure includes an alternating current electrode having the semiconductor elements on each of opposite surfaces, and a plurality of direct current electrodes holding therebetween the alternating current electrode and the semiconductor elements respectively mounted on the opposite surfaces of the alternating current electrode. Each of the alternating current electrode and the direct current electrodes has the cooling medium channels therein. | 07-22-2010 |
20080199763 | Sealed Battery - A battery cell comprising a battery housing case formed with a through hole communicating with an interior space, a hollow rivet, and a seal rubber. The hollow rivet has a seal surface annularly extending outside the battery housing case, and a hollow portion formed with an exhaust port continuous to the inner edge of the seal surface and positioned at the through hole to allow gas in the interior space to flow out through the exhaust port. The seal rubber has a contact unit extending annularly facing the seal surface to press the seal surface and is provided so as to close the exhaust port. The contact unit is formed to project toward the seal surface so as to contact the seal surface at a position away from the inner edge of the seal surface. Such an arrangement prevents an electrolyte leakage over a long period of time. | 08-21-2008 |
