| 20080200105 | Carrier film for mounting polishing workpiece and method for making the same - The present invention relates to a carrier film for mounting a polishing workpiece. The carrier film comprises a surface substrate and a buffer substrate. The surface substrate comprises holes, and the material of the surface substrate comprises elastomer. The buffer substrate comprises holes, and the material of the buffer substrate comprises the elastomer. The surface substrate and the buffer substrate are adhered with adhesive comprising the elastomer. A method for making the carrier film is also provided. When polishing, the carrier film provides a good buffer property to conduct and release down force applied on the polishing workpiece. | 08-21-2008 |
| 20110092142 | Retaining Rings - Retaining rings are presented with specially designed inserts that increase rigidity and improve heat dissipation. Inserts that are more rigid, and that have better ability to conduct heat, are inserted into pockets positioned along the outer portion of the rings. The pockets do not compromise the upper, lower or inner portion of the rings. Because the inserts are more rigid than the material used in the body of the ring, they absorb the deforming forces resulting from fastening the ring to the carrier head. Because they are better conductors than the material used in the body of the ring, the ring is better able to dissipate heat generated during polishing. Moreover, because the inserts are positioned in the outer portion of the ring, the inserts are not exposed to the polishing surface during polishing and therefore are less likely to react undesirably with the chemicals used during polishing. | 04-21-2011 |
| 20120094584 | SHEET FOR MOUNTING A WORKPIECE AND METHOD FOR MAKING THE SAME - The present invention relates to a sheet for mounting a workpiece and a method for making the same. The method includes the steps of: (a) providing a sheet body having a top surface, a bottom surface, at least one side surface and a plurality of pores, wherein some of the pores open at the side surface; and (b) sealing or narrowing the pores that open at the side surface. Since the pores that open at the side surface are sealed or narrowed, the slurry is prevented from entering into the interior of the sheet body. Therefore, the infiltration distance reaches a predetermined value slowly, thereby increasing the effective life of the sheet. | 04-19-2012 |
| 20160096252 | SKATE BLADE HOLDER TOOL GRASPING CENTRAL PORTION OF SKATE BLADE - A blade holder tool enables a user to insert the skate blade into a sharpener unit for sharpening. The skate blade is a user-removable skate blade having a central portion and endward portions that include blade retention features that engage a user-controlled blade retention mechanism of a skate to secure the skate blade in the skate. The blade holder tool includes an upper portion graspable by a user to hold the blade holder tool and place it in an inserted position in the sharpener unit. It further includes a lower blade-engaging portion that grasps the central portion of the skate blade and locates the skate blade in a sharpening position in the sharpener unit. Because it grasps skate blade in a central portion, the blade holder tool has a universal quality enabling it to be used with skate blades of a variety of sizes or lengths. | 04-07-2016 |

This arrangement enhances control when the device is used to sand or otherwise treat surfaces of target objects in corners/regions that are otherwise enclosed and awkward to access. In other aspects the interface body is provided with a skirt to protect the user from fluids; or with a front that is angled tapering towards a forward-most point whereby the media may ride up the walls of the tapering front. In a yet further aspect the interface has a reservoir for a treatment fluid, the reservoir being separable from the hand utility interface and formed as a vessel with a compressible concertina-form perimeter wall. | 03-22-2012 |

| 20140206266 | Never lost Grinder Nut - The purpose of this invention is to retain an abhor nut to a power tool while the nut is not in use. More specifically it is intended to keep the abhor nut of an angle grinder attached to the grinder. Grinding abrasives for an angle grinder can be purchased with or without a center hub. The abrasives that do not have a center hub make use of the abhor nut to secure them to the grinder. When an abrasive with a center hub is used on the grinder the abhor nut is not needed. The nut is removed from the abhor and frequently becomes misplaced. This invention keeps the grinder and nut together while the nut is not being used. This is designed for angle grinders, but could be used for other power tools and machinery. | 07-24-2014 |
