Abstract: A method for preparing a sintered magnet is provided according to one embodiment of the present disclosure. The method includes preparing a mixed powder by coating fluorides on a surface of magnetic powder, adding heavy rare earth hydrides to the mixed powder, and heating the mixed powder, wherein the magnetic powder includes rare earth element-iron-boron-based powder, and the fluorides include at least one of an organic fluoride or an inorganic fluoride.

Abstract: Disclosed are wood preforming devices for manufacturing a crash pad for a vehicle including a real wood sheet. A wood preforming device for manufacturing a crash pad for a vehicle includes a real wood sheet includes a lower press mold comprising a debossed portion provided on a portion on which a product is formed, and a support portion configured to support an upper press mold, in response to the lower press mold and the upper press mold pressing each other, the support portion having a protrusion for fixing a real wood sheet, the upper press mold having an embossed portion corresponding to the debossed portion of the lower press mold, and a movable core provided on the debossed portion of the lower press mold and being configured to guide the real wood sheet by moving upward from the debossed portion, in response to the upper press mold moving downward.

Abstract: The present invention relates to a scanner having a flexible probe which is an apparatus capable of being utilized for an inspection on a weld zone of a general ferrite material and a stainless material and allowing an inspection to be performed on a fitting weld zone where it is difficult for a general phased array ultrasonic testing (PAUT) probe to approach.

Abstract: A method for preparing a metal powder includes preparing a mixture by mixing a fluoride of a group 1 element, a fluoride of a group 2 element or a transition metal fluoride, with neodymium oxide, boron, iron, and a reducing agent; and heating the mixture at a temperature of 800° C. to 1100° C.
