20100322603 | SUBSTRATE ROTATING AND OSCILLATING APPARATUS FOR RAPID THERMAL PROCESS - Disclosed is a substrate rotating and oscillating apparatus for a rapid thermal process (RTP), that oscillates an oscillation plate using an oscillation motor moved by an elevating unit. Rotational shafts of the oscillation motor comprise lower and upper center rotational shafts mounted on a central axis of the motor, and an eccentric shaft mounted between the lower and the upper center rotational shafts as deviated from the central axis. An oscillation cam is mounted to the eccentric cam. The oscillation plate has an oscillation hole for inserting the oscillation cam therein. A bearing is mounted between the oscillation cam and the eccentric shaft such that the oscillation cam rotates independently from the eccentric shaft. The oscillation plate supports the whole multipole-magnetized magnetic motor or maglev motor. Accordingly, the substrate can be uniformly heated by both rotating and all-directionally oscillating the substrate. | 12-23-2010 |

20130005893 | POLYOLEFIN COMPOSITION FOR AN INTERIOR SHEET/FILM - The present invention relates to a polyolefin composition for an interior sheet/film. The polyolefin composition of the present invention for an interior sheet comprises 70 to 99 wt % of polyolefin and 1 to 30 wt % of modified polyethylene terephthalate having a melting point of 130 to 180° C. The polyolefin composition of the present invention is environmentally friendly and has good physical properties such as workability, printing characteristics, and adhesiveness. In addition, sheets having various thicknesses can be produced by extrusion without having to stretch the sheets, and thus the sheets can be used separately or in combination in various application fields. | 01-03-2013 |
