20150332820 | COMPOSITE MAGNETIC MEMBER AND METHOD OF MANUFACTURING SAME - A composite magnetic member configured so a nonmagnetic portion different from conventional ones is formed in part of a magnetic member and includes: a base portion including a mother material containing a ferrite phase; and a nonmagnetic portion having an austenite phase that is formed by solid solution of nitrogen (N) into a part of the mother material, the nonmagnetic portion having saturated magnetization less than that of the base portion. The nonmagnetic portion can be obtained by irradiating a high energy beam to a surface portion of stainless steel or the like while relatively moving the beam. This beam is near-ultraviolet nanosecond pulse laser having a short wavelength within a near-ultraviolet range and a pulse width of 10 ps to 100 ns. By adjusting the amount of N introduced and to form a solid solution due to the modification process, the nonmagnetization ratio of the member can be controlled. | 11-19-2015 |
20150348684 | MAGNETIC MATERIAL AND METHOD FOR PRODUCING MAGNETIC MATERIAL - An internal structure of a magnetic material is phase-separated into at least a first phase and a second phase. At least one of the first phase and the second phase includes a compound having a perovskite structure. The first phase and the second phase include Mn, Sn, and N. According to this, it is possible to obtain a magnetic material in which magnetic properties such as a coercive force are improved. In addition, in a case where a rare-earth element is not included in elements that constitute the magnetic material, it is possible to obtain a magnetic material having corrosion resistance. | 12-03-2015 |
20150357108 | SYSTEM AND METHOD FOR MOVING AN OBJECT - An improved system and method for moving an object includes a first correlated magnetic structure associated with a first object and a second correlated magnetic structure associated with a second object. The first and second correlated magnetic structures are complementary coded to achieve a peak attractive tensile force and a peak shear force when their code modulos are aligned thereby enabling magnetic attachment of the two objects whereby movement of one object causes movement of the other object as if the two objects were one object. Applying an amount of torque to one correlated magnetic structures greater than a torque threshold causes misalignment and decorrelation of the code modulos enabling detachment of the two objects. The number, location, and coding of the correlated magnetic structures can be selected to achieve specific torque characteristics, tensile force characteristics, and shear force characteristics. | 12-10-2015 |
20160104561 | MAGNET PLATE ASSEMBLY, DEPOSITION APPARATUS INCLUDING THE SAME, AND METHOD OF DEPOSITION USING THE SAME - Disclosed is a magnet plate assembly that includes a plurality of magnetic bodies, each magnetic body having a first surface formed to correspond to a flat surface of a substrate and to contact the flat surface of the substrate and a second surface formed in a different direction from that of the first surface, and a support frame which supports the plurality of magnetic bodies and has a plurality of grooves in which the plurality of magnetic bodies are respectively seated. | 04-14-2016 |
