Patent number: 6001472Abstract: A cleaning device and methodology therefor for cleaning a paper path surface upon which paper travels within a printing apparatus such as a computer printer, a photocopy machine, a fax machine, and the like. The cleaning device is a flexible substrate sheet having a first side and a second side, with the first side coated preferably in its entirety with an exposed adhesive having a tack strength between about 0.0002 and about 0.12 pound force-square inch. The second side of the substrate sheet can have laminated thereto a foam resin to provide a flexible thickness that assures pressured contact with all paper path surfaces to be cleaned. A lint-free cloth layer can be laminated to the foam resin if present, or the cloth layer can be laminated directly to the second surface of the sheet substrate. operability occurs as the substrate sheet is fed into the printing apparatus and travels there through along the paper-path surfaces upon which paper is conveyed.Type: GrantFiled: October 23, 1998Date of Patent: December 14, 1999Assignee: No Touch North AmericaInventors: Atsushi Ikeda, Nobuhiro Yoshikawa

Patent number: 5994245Abstract: A laminated insole (2) for a footwear has an upper layer (4) of a resilient foam material having an outline (6) shaped for incorporation in the footwear, and a bottom layer of a fibrous mat (10) and having a shape conforming with the outline (6) of the upper layer (4). The fibrous mat (10) includes a multiplicity of fibers (12), a number of which penetrate the foam material of the upper layer (4) for bonding the bottom layer (10) to the upper layer (4), and a stiffening portion (14) for providing stiffness to the insole (2). Preferably, each of the fibers (12) of those penetrating the foam material (4) emerges from the outer surface (16) thereof and thereby provides a pilosity (17) thereon. The laminated product (2) is suitable for use as an insole as well as a slip-in insole in any footwear. It takes advantage of the resilient properties of the foam, the stiffness and thermoformability of the fibrous mat and the comfort provided by the pilosity covering the upper layer of foam.Type: GrantFiled: May 20, 1998Date of Patent: November 30, 1999Assignee: Texel Inc.Inventors: Andre Marier, Gerard Scheubel, Barbara Redfern

Patent number: 5989707Abstract: A material sheet assembly in which a label base attached to a release liner by means of an adhesive is set in roll form is used. In a step in which the material sheet assembly is continuously fed out, the release liner is released by leaving the adhesive on the label base, and the release liner is consecutively taken up. By using a noncontact-type printer, printing is effected on the adhesive surface of the label base separated from the release liner to form a printed label. The printed label is in such a form that the printed surface is disposed between the label base and an adherend. The labels can be attached immediately after they are manufactured, and they can be stored or transported by being taken up in roll form while an additional release liner is attached to the printed surface side.Type: GrantFiled: October 26, 1998Date of Patent: November 23, 1999Assignee: Lintec CorporationInventors: Yoshinobu Takizawa, Fumihiko Goto
