| 20100210808 | METHOD FOR PREPARING POLYSILAZANE SOLUTION WITH REDUCING AMMONIA SUBSTITUTION OF SI-H BOND - The present disclosure relates to a method of preparing polysilazane and a polysilazane solution which can minimize substitution of an Si—H bond of a starting compound by ammonia. Particularly, a method of synthesizing polysilazane using a solution which undergoes phase separation and a method of preparing a polysilazane solution for a wafer are disclosed. The method of preparing polysilazane using halosilane and liquid anhydrous ammonia includes adding liquid anhydrous ammonia to a solvent in a weight ratio of 0.5:1 to 10:1, followed by stirring to prepare a mixture solution, and allowing pseudo-ammonolysis to be carried out by adding halosilane to the mixture solution separated into two phases. | 08-19-2010 |

| 20090040002 | Iron Core, Mold and Method of Forming and Laminating the Same - An iron core built in a transformer, a rectifier, a stabilizer, a lamp, and others is disclosed. When the iron core is formed, an E-shaped iron core and a pair of ⊂-shaped iron cores, which are arranged on both sides of the E-shaped iron core, are simultaneously stamped from a sheet of silicon steel. A predetermined number of E-shaped iron cores and pairs of ⊂-shaped iron cores are assembled and laminated to form a laminated iron core. The iron core includes the E-shaped iron core having side legs symmetrically formed on both sides thereof and a center leg formed between the side legs and coupled to a bobbin around which a coil is wound, and the pair of ⊂-shaped iron cores each having a long leg formed corresponding to the side leg of the E-shaped iron core and a short leg formed corresponding to the center leg of the E-shaped iron core. | 02-12-2009 |
