| 20100264607 | GASKET - A gasket having a concentrically waved metal sheet, i.e., a core member, which has a PTFE sheet or an inorganic sheet of sealing-property layered and bonded on each of its opposite surfaces. The gasket makes it possible to ensure a stable sealing-property for a long period of time with a low to a high fastening-load applied. The metal sheet has valley portions, which were conventionally vacant gaps, and are filled with powdered sealing member to be embedded from the beginning. Therefore, the PTFE sheet or the inorganic sheet at the valley portions of the metal sheet that conventionally could not be compressed with a low fastening-load applied is compressed and even with the low fastening-load applied can secure a fastening surface-pressure over the entire surface. Further, since it is possible to suppress the deformation of the sheet in quantity, which was conventionally large, the PTFE sheet or the inorganic sheet each of low-fluidity are arranged so as not to be broken with a high fastening-load applied and the thinner PTFE sheet or the thinner inorganic sheet can be used. | 10-21-2010 |
| 20100237570 | GASKET - A gasket having a concentrically waved metal sheet, i.e., a core member, which has a sheet of sealing-property layered and bonded on each of its opposite surfaces. The gasket has an enhanced adaptability of the sheet material and enables the thinner sheet to be used and at the same time makes it possible to ensure a stable sealing-property for a long period of time with a low to a high fastening-load applied. The metal sheet has valley portions, which were conventionally vacant gaps, and are filled with powdered sealing member to be embedded from the beginning. Therefore, the sheet at the valley portions of the metal sheet that conventionally could not be compressed with a low fastening-load applied can be compressed and even with the low fastening-load applied can secure a fastening surface-pressure over the entire surface. Further, since it is possible to suppress the deformation of the sheet in quantity, which was conventionally large, a sheet made of not only the high-fluidity material but also the low-fluidity material can be used as well as the thinner sheet. | 09-23-2010 |
| 20100159357 | Separator for Fuel Cell and Process for Producing the Same - In order to attain excellent electrical conductivity and molding processability, a fuel cell separator to be produced by performing press molding on a preform in which expanded graphite is used as the main raw material is improved so that the preform is produced by a papermaking method, whereby the characteristics of the mechanical strength, the flexibility, and the gas impermeability are improved, and a light and compact configuration that is preferred in the automobile use or the like can be realized.
