Abstract: A plurality of arcuate, circumferentially extending leaf seal segments form an annular seal spanning between annular sealing surfaces of inner and outer casings of a turbine. The ends of the adjoining seal segments have circumferential gaps to enable circumferential expansion and contraction of the segments. The end of a first segment includes a tab projecting into a recess of a second end of a second segment. Edges of the tab seal against the sealing surfaces of the inner and outer casings have a narrow clearance with opposed edges of the recess. An overlying cover plate spans the joint. Leakage flow is maintained at a minimum because of the reduced gap between the radially spaced edges of the tab and recess, while the seal segments retain the capacity to expand and contract circumferentially.

Abstract: A water-resistant function can be maintained even in the case where a substrate is interposed between packings. Packing has a rib-shaped convex portion having a uniform height and width on a surface contacting a flexible substrate. The packing with such a convex portion is fitted in grooves provided in a body and a back cover. The rib-shaped convex portion disposed on the packing is biased to an edge portion of the substrate when a housing is closed, and is elastically deformed in a direction in which it comes into close contact with a side surface portion of the substrate. Thus, the convex portion disposed on the packing blocks up a gap generated in the vicinity of the side surface of the substrate and has a functional effect of suppressing water from entering.

Abstract: An improved releasable and reusable self-sealing plug for mechanically sealing a bore. A cylindrical body is formed on its outer surface to retain radial sealing means such as an O-ring. An oversize annular cap at the outer end of the body limits ingress of the plug into a bore, and a pair of opposed, flexible limbs terminating in flanges beyond the inner end of the body are compressed radially during insertion of the plug and spring out at completion of insertion to grip the inner entrance to the bore, thus holding the O-ring and plug in the bore. Insertion may be accomplished manually without the aid of tools. The plug cannot be driven out by pressure on the bore, but is easily removed by recompression of the limbs and flanges and withdrawal of the plug by, for example, needle-nose pliers. The plug may be formed inexpensively and easily by injection molding of a suitable plastic polymer.

Abstract: In sealing means for a slider unit in which sealing members of foam rubber are arranged to close sidewise clearances left open between a dustproof cover and side walls of a track rail, the improved sealing means is directed to making sure of effective sealing performance, prolonging a durable service life of the sealing member, and also making mounting of the sealing member to the clearances easier. Sealing members of flexible foam rubber rich in restoring force are arranged in the clearance between the dustproof cover and the side walls of the track rail. The sealing members, while fastened to the dustproof cover, are allowed to experience any deformation of expansion/collapse when sideward wings of the slider moves back and forward between the confronting sealing members and the side walls, with keeping close sliding engagement with the associated surfaces of the wings.

Abstract: Gas purification resins are encapsulated in deformable, permeable polymer sheaths to form purification rings, gaskets or seals. A primary source of contaminants in advanced vacuum processors equipped with vacuum load-lock systems and process gas purifiers is from the leakage of outside ambient contaminants around O-ring seals. Using gas purification rings, gaskets or seals properly placed inside or outside of the outer O-ring seal, the level of contaminants (particularly hydrocarbons, oxygen and moisture) may be significantly reduced or eliminated. The gas purification ring is preferably a hydrocarbon and/or oxygen and/or moisture absorbing and/or adsorbing material encased within a contaminant permeable casing. The gas purification ring can be round or flattened and is preferably more resilient than the O-rings adjacent thereto which form the seal. An adhesive can be placed around the casing holding the purification resin to prevent movement from its purifying location.

Abstract: The present inventions provide a fusible seal for sealing liquid crystal display (LCD) devices. A fusible seal is formed on a transparent plate or on a die having a pixel array. The fusible seal is configured to encircle the pixel array of the die when the die and the transparent plate are joined. The die and the transparent plate are joined together such that the fusible seal is disposed between the transparent plate and the die. Heat is locally applied to the fusible seal without significantly heating the transparent plate or the die. Heating the fusible seal fuses the transparent plate to the die and encloses the pixel array. A LCD device is thereby formed without the need to cure the entire LCD device, which often times causes warping of the LCD device.
