20110256817 | POLISHING PAD AND METHOD FOR PRODUCING SAME - An object of the invention is to provide a polishing pad that achieves a high polishing rate and has high thickness precision so that the break-in time (dummy polishing time) can be shortened, and to provide a method for producing same. The invention is directed to a polishing pad including a base material layer and a polishing layer provided on the base material layer, wherein the polishing layer includes a thermoset polyurethane foam having roughly spherical interconnected cells with an average cell diameter of 35 to 200 μm, and the polishing layer has a storage modulus E′ (40° C.) of 130 to 400 MPa at 40° C., a ratio of storage modulus E′ (30° C.) at 30° C. to storage modulus E′ (60° C.) at 60° C. [E′(30° C.)/E′(60° C.)] of 1 to less than 2.5, and a ratio of storage modulus E′ (30° C.) at 30° C. to storage modulus E′ (90° C.) at 90° C. [E′(30° C.)/E′(90° C.)] of 15 to 130. | 10-20-2011 |
20130035021 | POLISHING PAD, MANUFACTURING METHOD THEREFOR, AND METHOD FOR MANUFACTURING A SEMICONDUCTOR DEVICE - A polishing pad having a polishing layer comprising a thermoset polyurethane foam, wherein the thermoset polyurethane foam contains, as raw material components, an isocyanate component, and active-hydrogen-containing compounds, and the active-hydrogen-containing compounds comprise one or more polyol compounds (each) having two or more functional groups, and a monool compound having one functional group. | 02-07-2013 |

20150291480 | ARTIFICIAL SOIL MEDIUM - Provided is a technique of continuously supplying moisture to a plant to be grown over a long period of time or highly controlling the amount of moisture supplied to a plant to be grown, depending on the plant, in an artificial soil medium including a collection of artificial soil particles. An artificial soil medium | 10-15-2015 |
20150313102 | ARTIFICIAL SOIL AGGREGATE AND ARTIFICIAL SOIL MEDIUM - An artificial soil aggregate which is an aggregate of artificial soil particles is provided. When an artificial soil is formed by filling a container, such as a planter, etc., with the artificial soil aggregates, the volumetric moisture content rate and gas phase fraction of the artificial soil can be improved, and can also be maintained over a long period of time. The artificial soil aggregate is an aggregate of artificial soil particles in which a plurality of fillers having a small hole ranging from the subnanometer to the submicrometer scale are clustered together. A communication hole ranging from the submicrometer to the submillimeter scale is formed between the fillers. The artificial soil aggregate has a volumetric moisture content rate of 10 to 40% at a pF ranging from 1.7 to 2.3, and a gas phase fraction of 20 to 80% at a pF of 1.5. | 11-05-2015 |
20150319945 | ARTIFICIAL SOIL MEDIUM - In an artificial soil medium including a collection of artificial soil particles, provided is a technique of allowing an appropriate nutrient(s) to be released during each growth stage of plant to be grown, or highly controlling the amount of a nutrient(s), depending on a plant to be grown. An artificial soil medium | 11-12-2015 |
