  • Publication number: 20130228984
    Abstract: In order to inexpensively provide gaskets which have good sealing performance, and which fulfill various applications by simply stamping out sheet-like gaskets in accordance with specifications, a gasket is obtained by integrally forming, with a sheet-like base material, a gasket part made of a rubber-like elastic material on at least one surface of the base material, said gasket part being composed of continuous protrusions provided with a fixed pattern. The sheet-like gasket parts produced in this manner are capable of inexpensively providing gaskets which fulfill various applications by simply stamping out the sheet-like gasket parts in accordance with various specifications.

  • Publication number: 20130161914
    Abstract: The embodiments described herein provide a cloth seal for use with turbine components. The cloth seal includes first and second cloth layers. One or more central shims are positioned between the first and second cloth layers so as to block a leakage flow path. Another shim is positioned on and seals the opposite side of the first cloth layer from the one or more central shims positioned between the first and second cloth layers so as to block another leakage flow path. Yet another sealing shim may be positioned on the opposite side of the second cloth layer from the one or more central shims positioned between the first and second cloth layers to as to seal the opposite side of the second cloth layer and block another leakage flow path.

  • Patent number: 8424878
    Abstract: A device including a metal substrate and a ceramic substrate including a back-tapered groove separated from each other by a sealed flexible link. The link includes: a metal element including an end connected to the metal substrate and at another end housed in the groove of the ceramic substrate, the metal element being elastically deformable both in the groove along a direction radial to the groove and, in the separation space between the metal substrate and the ceramic substrate along the separation direction, and a joint-forming mass with a greater thermal expansion coefficient than that of the ceramic substrate and adhesively bonded to the end of the metal element housed in the back-tapered groove, the joint fitting with direct contact a portion of the height of convergent sidewalls of the groove.

  • Patent number: 8408557
    Abstract: The seal arrangement (154) is arranged between the casing portions (50,52) and a fluoropolymer O-ring seal (72) is positioned between the casing portions (50,52). A first protecting member (156) is positioned between the fluoropolymer O-ring seal (72) and the casing portion (50) and the first protecting member (156) consists of a polymer and hydroxyapatite. The first protecting member (156) consists of 50 to 80 wt % polymer and 20 to 50 wt % hydroxyapatite and incidental impurities. The first protecting member (156) is located in an annular groove (70) and is thus arranged between the casing portion (50) and the fluoropolymer O-ring seal (72). The first protecting member (156) is substantially U-shaped in cross-section and the fluoropolymer O-ring seal (72) is positioned between the legs of the U-shaped cross-section first protecting member (156). The first protecting member (156) prevents corrosion of the casing portion (50) by the fluoropolymer O-ring seal (72).

  • Patent number: 8400730
    Abstract: A multi-stage gasket having a multi-stage structure constituted by multiple kinds of gasket materials and being used by holding between a cover plate and a base plate, the multi-stage gasket having contactness of a gasket as the lowermost layer to the cover plate or the base plate in contact with the gasket that is higher than contactness of a gasket as the uppermost layer to the cover plate or the base plate in contact with the gasket. A gasket can be provided that provides good reworkability of a cover plate and a base plate of a hard disk device, provides sufficient adhesiveness of the gasket to a cover plate and a base plate even when used in a high humidity and temperature environment, and is prevented from being toppled sideways or peeled off even when applied with a force in an oblique direction.

  • Patent number: 8382122
    Abstract: 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.

  • Patent number: 8376370
    Abstract: 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.

An outer seal ring portion is surrounded by a scribe line, surrounding the inner seal ring portion, wherein the outer seal ring portion has an outer top metal layer pattern with a first width extending over the inner seal ring portion and connecting to an inner next-to-top metal layer pattern of the inner seal ring portion. A first redistribution pattern is disposed on the outer top metal layer pattern, having a second width which is narrower than the first width. A second redistribution pattern is disposed on the first redistribution pattern. A redistribution passivation layer covers the second redistribution pattern and the inner seal ring portion, wherein the redistribution passivation layer is separated from the scribe line by a second distance.
