Abstract: Provided is a welding management system that appropriately manages welding. The welding management system (100) includes a plurality of local magnetic sensors (10a to 10f) provided around a target joining position (K) and a correction magnetic sensor (20) curved to surround the target joining position (K). A data processing unit (30) generates information of a joining state of the target joining position (K) based on a difference between a detection value of each of the plurality of the local magnetic sensors (10a to 10f) and a detection value of the correction magnetic sensor (20).

Abstract: The present invention provides a method of quickly freezing vegetables, whose cells are broken and commercial value is lost when processed by a conventional freeze-preservation method, and stocking them in a freezing environment. The method according to the present invention comprises the first step of adding at least one selected from a group consisting of monosaccharide, disaccharide, oligosaccharide and sugar alcohol and polysaccharide, with or without salts, to vegetables to pickling them for several hours, the second step of quickly freezing the vegetables processed in the first step and the third step of storing the quickly frozen vegetables in a freezing environment. Polysaccharides surround cells of vegetables to remove water content of cells and protect them and monosaccharide, disaccharide, oligosaccharide and sugar alcohol and/or salts permeates into cells and is replaced with water content to prevent growth of water crystal.

Abstract: A three dimensional machining system includes a three dimensional measuring unit which is separate from a three dimensional machine which actually applies a machining operation upon a three dimensional object. In this manner, a teaching operation with respect to an object to be machined can be performed during the machining operation by the three dimensional machine, thus improving the working efficiency of the three dimensional machine.
