  • Patent number: 6177174
    Abstract: An armor coating (3) is provided on a surface of a metal engine component (1) that is adapted to be in grazing contact with an abradable bedding-in seal lining provided on a second engine component. The armor coating (3) includes a ceramic layer (6) and has a profiled surface contour including peaks (4, 7, 9, 10) and depressions or grooves (5) therebetween. The grooves (5) serve to receive and carry away abrasion material that is abraded from the bedding-in lining. The profiled surface contour is formed in the surface (2) of the engine component (1) by cold deformation without material removal, and thereafter the ceramic layer (6) is applied thereon preferably by thermal spraying, such that the layer (6) follows and also embodies the profiled surface contour. The cold deformation is carried out by pressing a knurling tool (11) into the original un-profiled surface (2) of the component (1).

Preferably, the thickness of the glass top plate separating each plasma discharge from an electro-optic pixel is made substantially uniformly thin while the side walls reinforce and greatly increase the strength of the plate making it less prone to breakage during assembly of a display panel. Preferably, the glass plate is etched by means of a plasma etching process.

  • Patent number: 5620777
    Abstract: A porous rubber stamp material having open cells is here disclosed which comprises a print layer 2 having a spring hardness of 30 to 40 and an ink-occluding layer 1 having a spring hardness of 10 to 20, and preferably, the ink-occluding layer 1 is provided with lugs 3. The porous rubber stamp material of the present invention can overcome faults of a conventional porous rubber stamp material having open cells and permits obtaining a very sharp imprint under any push pressure. Thus, the porous rubber stamp material of the present invention can be used for the continuous sealing of a private seal, an address seal, a date seal and the like.

    Abstract: An embossed tissue having improved bulk and puffiness while being non-nesting by having a lattice pattern and at least two signature bosses. More particularly, one of the signature bosses is defined by embossments having a lower portion which is continuous and an upper portion which is defined by crenels and merlons.

  • Patent number: 5614287
    Abstract: The reproduction characteristics, particularly the C/N ratio of a reproduced signal of an optical recording medium are deteriorated by an unevenness or deformation of an optical recording layer due to a convex or concave configuration of underlying guide means that are formed on the surface of the substrate. This deterioration can be prevented by disposing a leveling layer under the recording layer, but the leveling layer lowers the efficiency of the servo tracking. This lowering of servo tracking efficiency is prevented by insertion of a dielectric layer between the leveling layer and the guides.

  • Patent number: 5597639
    Abstract: The perceived softness of embossed tissue can be increased greatly while avoiding nesting when a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike bosses with deeper more sharply defined signature bosses. The stitchlike bosses can be rounded and arranged in wavy flowing intersecting lines. The signature bosses can be arranged in regions framed by the intersecting wavy flowing lines.

  • Patent number: 5589247
    Abstract: Coated polymeric sheet comprising polymer substrate a cross-linked polymer, wherein the coating is characterized by:A. As being smooth, having a surface roughness not greater than 0.05 nanometers R.sub.a, except that;B. in the otherwise smooth surface, a multiplicity of depressions having depth ranging from 1 to 90% of the thickness of the coating.Backside coatings (containing carbon black in the cross-linked polymer) for magnetic recording tapes benefit from this invention by improved winding characteristics. The concept described is a replacement for rough random surface texture, formerly used in backside coatings, with a controlled surface texture. The process disclosed can also be used to make alphanumeric symbols on the pigment binder coating.

  • Patent number: 5578362
    Abstract: The present invention relates to an article of manufacture or polishing pad for altering a surface of a workpiece, such as polishing or planarizing a semiconductor device. The article includes a polymeric matrix impregnated with a plurality of polymeric microelements, each polymeric microelement having a void space therein. The article has a work surface and a subsurface proximate to the work surface. When the article is in contact with a working environment, polymeric microelements at the work surface of the article are less rigid than polymeric elements embedded in the subsurface. As the work surface of the article is abraded during use, the work surface of the pad may be continuously regenerated. In alternative preferred embodiments, the work surface may further include a minitexture and/or a macrotexture. Preferably, the minitexture is formed by fractal patterning at least a portion of the work surface.

  • Patent number: 5576090
    Abstract: This invention provides an exceptionally expandable sheet elastic complex which consists of an elastic body sheet and a sheet backing material which is mounted on either one or both sides of it, these two members being bonded together along multiple, oblong, mutually parallel bonding sections, and in which multiple, mutually parallel channels are formed between the two members because the width of the sheet backing material between mutually adjacent bonding sections is greater than that of the elastic body sheet. The sheet backing material does not accept more than the minimum constraint of the elastic body sheet, and its waveform surface has excellent properties as a material for use in sanitary products. The invention also provides a process for manufacturing this sheet elastic complex.

  • Patent number: 5562797
    Abstract: To form a seam of attractive appearance, a heated platen having a shaped lip acts to engage and press the central surface of an adhesively-backed sheet of a polymeric fabric against the top appearance surface of a panel and the peripheral edge of the sheet into a groove formed in the surface, the platen activating the adhesive and the lip forcing a potion of the adhesive inwardly adjacent to the sheet edge against one wall of the groove. An insertion blade presses a portion of the sheet edge towards the bottom of the groove, the blade acting as a heat shield to space and protect the other wall of the groove from the heated platen.

  • Patent number: 5554432
    Abstract: The present invention is a lenticular sheet having lenticles over only a portion of the sheet. The lenticular sheet is formed by bonding a base substrate to a thermosetting polymer sheet having a lenticular array on its top surface. In one embodiment of the invention, a lenticulated image is printed on the top surface of the base substrate. In a second embodiment of the invention, the lenticulated image is printed on the bottom surface of the base substrate. In another embodiment of the invention, which can be used with either of the first two embodiments, text or other material is printed on a portion of the base substrate not underlying lenticles and not having the lenticulated image printed thereon.

    Abstract: The magnetic recording medium includes at least a substrate, a magnetic film formed on the substrate for storing data, a protective film and a lubricant film. The protective film has two regions of a predetermined pattern each having a different surface energy. The lubricant film including polar groups is formed on the protective film including the regions. The degree of adhesion of the lubricant film to the protective film is thus changed at the two regions each having a different surface energy so that the lubricant film can be prevented from being scattered.
