Patent number: 7303804Abstract: A pile fabric comprises a base fabric and a pile layer composed of many cut piles extending from at least one face of the base fabric, and has a pile length of from 2 to 30 mm. The pile yarns forming the cut piles are core-sheath type composite yarns each comprising a core portion composed of thick fibers (preferably filaments) having a single fiber size of from 5 to 55 dtex and a sheath portion that is composed of thin fibers (preferably filaments) having a single fiber size of from 0.01 to 2.5 dtex, and that surrounds and covers the core portion. The pile fabric is excellent in the dust removal effect during wiping, and resistance to laying flat, and is useful as a fabric for cleaning.Type: GrantFiled: April 7, 2003Date of Patent: December 4, 2007Assignee: N.I.

Patent number: 7223469Abstract: Moldable capsules of a conductive loaded resin-based material are created. The moldable capsules include a conductive element core radially surrounded by a resin-based material. The conductive loaded resin-based material includes micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The conductive element core includes between about 20% and about 50% of the total weight of the moldable capsule in one embodiment, between about 20% and about 40% in another embodiment, between about 25% and about 35% in another embodiment, and about 30% in another embodiment. The micron conductive powders are formed from non-metals, that may also be metallic plated, or from metals, that may also be metallic plated, or from a combination of non-metal, plated, or in combination with, metal powders. The micron conductor fibers preferably are of nickel plated carbon fiber, stainless steel fiber, copper fiber, silver fiber, or the like.Type: GrantFiled: July 1, 2004Date of Patent: May 29, 2007Assignee: Integral Technologies, Inc.Inventor: Thomas Aisenbrey

Patent number: 7162180Abstract: The present invention provides an improved elastic material which is free of roller abrasion when used in development rollers and overcomes disadvantages of the conventional silicone rollers of deterioration in the abrasion resistance, an elastic roller employing such elastic materials, and an electrophotographic apparatus and electrostatic recording apparatus incorporating such rollers. The elastic material satisfies a relationship represented by the following equation: log{(Tb·Eb)?1}??0.0011(Hd)2+0.1154(Hd)?5.6 where Tb is the tensile strength (N/mm2), Eb is the tension fracture elongation (%) and Hd is the Asker C hardness (°). Further, the present invention provides a novel developer carrier for use with an imaging apparatus and an imaging apparatus incorporating the developer carrier. The developer carrier includes an electrically conductive elastic layer and is arranged in contact with, or in the proximity of, an imaging body.Type: GrantFiled: August 30, 2000Date of Patent: January 9, 2007Assignee: Bridgestone CorporationInventors: Yoshio Takizawa, Yuichiro Mori, Shu Inoue, Ryuta Tanaka
