Patent number: 8604489Abstract: A mask frame assembly for thin film deposition includes a frame including an opening portion, and a plurality of unit mask strips that are fixed to the frame after a tensile force is applied to both of end portions of the unit mask strips in a lengthwise direction of the unit mask strips. Each of the plurality of unit mask strips includes a plurality of unit masking pattern portions each including a plurality of opening patterns. Before the tensile force is applied to both of the end portions of the unit mask strips in the lengthwise direction and the unit mask strips are fixed to the frame, a width of each of the unit masking pattern portions in a widthwise direction perpendicular to the lengthwise direction increases as a function of a closeness of a portion of the unit masking pattern portion where the width is measured to a central portion of each of the unit masking pattern portions.Type: GrantFiled: January 10, 2011Date of Patent: December 10, 2013Assignee: Samsung Display Co., Ltd.Inventors: Jae-Min Hong, Kyung-Han Kim, Ho-Eoun Kim

Patent number: 6891455Abstract: A gravity control apparatus is provided, in which is controlled through the superconducting coil designed for generating uniform magnetic force. The gravity control apparatus includes a hollow cylindrical low temperature container; a combination of B0 coil and a symmetric and/or asymmetric gradient magnetic field generating coil having a predetermined length and inner and outer radiuses, wherein each of B0 coil and gradient magnetic field generating coil is wound onto a bobbin which is installed to the low temperature container so as to form a superconducting magnet, and the B0 coil has three solenoid coils which are arrayed in three parts with a predetermined spacing so as to generate, from the center of the B0 coil, uniform magnetic field having constant magnetic flux density; and a power unit for supplying operating current to each of coils. Thus, gravity acting on the material disposed in the hollow center of the low temperature container can be compensated with a uniform magnetic force.Type: GrantFiled: September 17, 2001Date of Patent: May 10, 2005Assignee: Duksung Co., Ltd.Inventors: Hong-Beom Jin, Ki-Deok Sim, Byeung-Sang Park, Hyung-Jin Kim, Ho-Hwan Han, Kyung-Han Kim, Suk-Jin Choi
