    摘要： The present invention provides an abrasive article that has abrasive composite members secured firmly in recesses in a backing sheet in a precise pattern whereby there is desired lateral spacing between each abrasive composite member. The present invention also provides a method for preparing the abrasive article comprising the steps of providing an embossed backing sheet having a plurality of recesses in the front surface of the backing sheet. The recesses are filled with an abrasive slurry that includes a plurality of abrasive grains dispersed in a binder precursor. An expanding agent is also provided in the recesses, either separate from the slurry or dispersed in the slurry. The expanding agent, when activated, expands the abrasive slurry outward and above the front surface of the embossed backing sheet. After the binder precursor of the abrasive slurry is hardened, individual abrasive composite members extend above the front surface of the embossed backing sheet. An alternative embodiment provides recesses that extend completely through the embossed backing sheet, so that abrasive composite members protrude from the front surface and from the back surface of the embossed backing sheet.

    摘要翻译： 本发明提供了一种磨料制品，其具有以精确图案牢固地固定在底片中的凹部中的磨料复合构件，由此在每个磨料复合构件之间存在期望的横向间隔。 本发明还提供了一种制备磨料制品的方法，包括以下步骤：提供在背衬片的前表面中具有多个凹槽的压纹背衬片。 凹部填充有包含分散在粘合剂前体中的多个磨料颗粒的磨料浆料。 还可以在凹槽中提供发泡剂，或者与浆料分离或分散在浆料中。 膨胀剂在被活化时，将研磨浆料向外凸出并压印在背衬片的前表面上方。 在研磨浆料的粘合剂前体硬化之后，各个研磨复合材料部件在压花背衬片材的前表面之上延伸。 替代实施例提供了完全延伸穿过压花背衬片的凹部，使得磨料复合构件从压花背衬片的前表面和后表面突出。

    摘要： A method for polishing a wafer comprising an aqueous solution having a pH in the range of 6 to 8, wherein the aqueous solution comprises at least one compound selected from the group consisting of a polymethacrylic acid, a polysulfonic acid, and combinations thereof, and wherein the compound is present in the range of 1.5 to 4 percent by weight of the aqueous solution. The wafer polishing solution can be adjusted to control cut rate and selectivity for modifying semiconductor wafers using a fixed abrasive CMP process.

    摘要： The present invention is an article useful in the field of wafer processing, for example. The article includes a substrate, a leveling layer, a joining layer, a photothermal conversion layer and a temporary carrier. The substrate has a first major surface, a second major surface and at least one three dimensional topographical feature extending from the first major surface and having an initial step height. The leveling layer is positioned adjacent to the first major surface and reduces a topography of the substrate to between about 5% and about 95% of the initial step height. The joining layer is positioned adjacent to the leveling layer and further reduces the topography of the substrate to less than about 20% of the initial step height. The photothermal conversion layer is positioned adjacent to the joining layer and the temporary carrier is positioned adjacent the photothermal conversion layer.

    摘要： A modular in-wall medical services unit for medical care facilities. A frame supports a cabinet with a cover panel providing electrical and/or gas outlets. Built-in electrical and gas conduits are included. A junction box and ends of the gas conduits near the top of the frame are accessible after wallboard is applied. Thus, wallboard can be installed before or after wiring is completed and gas connections are made. The self-aligning cover panel is “floatingly” supported on the frame so that a bead of sealant can be applied around the edge before the cover panel is “snugged up” to the wall and secured. The trim flanges on the cover panel include vertical equipment mounting tracks. Manufacturing is simplified by making the height of the frame adjustable; the same frame elements can be used to assemble units for different ceiling heights, decreasing the number of required parts in inventory and expediting assembly.

    摘要： Provided is a laminated body comprising a substrate to be ground and a support, where the substrate may be ground to a very small (thin) thickness and can then be separated from the support without damaging the substrate. One embodiment is a laminated body comprising a substrate to be ground, a curable silicone adhesive layer in contact with the substrate to be ground, a photothermal conversion layer comprising a light absorbing agent and a heat decomposable resin, and a light transmitting support. After grinding the substrate surface which is opposite that in contact with the adhesive layer, the laminated body is irradiated through the light transmitting layer and the photothermal conversion layer decomposes to separate the substrate and the light transmitting support.
