  • Publication number: 20210207010
    Abstract: [Problem] To provide a thermally expandable adhesive sheet which is tack-free in the state prior to use and exhibits high workability using a different means than that of related art. [Solution] The present invention provides a thermally expandable adhesive sheet (1) including: a substrate (3); two thermally expandable adhesive layers (5) each provided on either side of the substrate; and two adhesive permeable layers (7) each provided on a surface of the two adhesive layers, the adhesive permeable layers being permeable to the adhesive at the time of the thermal expansion of the adhesive. By heating the adhesive sheet, it is possible to expand the adhesive sheet while simultaneously allowing the adhesive to emerge on the outermost surface of the adhesive sheet.

  • Patent number: 9062118
    Abstract: The invention relates to relatively short peptides (termed J-Superfamily conotoxin peptides, J-conotoxins or J-conotoxin peptides herein), about 25 residues in length, which are naturally available in minute amounts in the venom of the cone snails or analogous to the naturally available peptides, and which preferably include two disulfide bonds. The J-conotoxins are useful for treating disorders involving voltage gated ion channels and/or receptors.

  • Patent number: 7973241
    Abstract: A pressure restraining enclosure for cables can include, for example, a first cable including a conductor and an oil-containing layer surrounding the conductor, and a second cable having a conductor. A splice can connect the conductor of the first cable with the conductor of the second cable. A pressure restraining sleeve can overly the splice and the conductors of the first and second cables. Several fasteners can be applied to several locations on the pressure restraining sleeve to tighten the pressure restraining sleeve around the splice and portions of the first and second cable. Embodiments of the pressure restraining enclosure can be used in the form of a sleeve on a single core cable, or alternatively as a body and a separate sleeve on multiple core cables such as three-core cables.

  • Publication number: 20090065236
    Abstract: A cable has a conductor extending therefrom and a partially exposed fluid-containing layer surrounding the conductor. A connector is joined to an end of the conductor, and an electrically insulative, elastomeric tube is covers all of the exposed fluid-containing layer and a portion of the connector. The elastomeric tube is substantially impermeable to the fluid in the cable. For cables having more than one conductor, an additional elastomeric boot is installed over the cable.

  • Patent number: 6701580
    Abstract: An interlocking fastener, preferably in the form of an elongate strip, holds at least one object in a substantially immobile condition. The interlocking fastener comprises a backing sheet having a first side opposite a second side and a first end opposite a second end. A plurality of first connecting elements, attached to the first side of the backing sheet, releasably engage a plurality of second connecting elements attached to the second side of the backing sheet during formation of a wrapped fastening strip. The interlocking fastener has a deposit of a pliable material at a plurality of boundaries between areas of the connecting elements on at least the first side of the backing sheet to provide at least frictional contact immobilizing the object to substantially prevent it from moving following formation of the wrapped fastening strip by overlap of the first end and the second end.
