Title: Mig welding method
Inventor: YUGUCHI TOMOHITO
IPC: B23K9/16
Filed: 2013-11-08
Abstract: PROBLEM TO BE SOLVED: To surely prevent the generation of rust on the surface of a base metal which undergoes electrodeposition due to non-deposition of a paint or peeling of a deposited paint in a MIG welding method for welding the base material.SOLUTION: A COgas 100% rich in oxidizing components is used as a shield gas 3 and a welding wire 6 is moved along a weld line 2 to form an auxiliary bead 4 containing an oxidizing substance. Thereafter, Ar gas 100% is used as a shield gas 7 and the welding wire 6 is moved along the auxiliary bead 4 to form a weld bead 8 wider and bulkier than the auxiliary bead 4. As a result, the weld bead 8 can be formed with no meander by moving an arc A just like the weld line 2 while the arc A is induced by the oxidizing substance contained in the auxiliary bead 4 along the weld line 2, so that the weld bead 8 free of slug can be formed by the stable arc A, and even when a base metal 1 undergoes electrodeposition thereafter, high quality painting can be carried out generating neither non-deposition nor peeling of the paint.

Title: Silicon carbide crystal growth method
Inventor: YAMAGATA NORIO
IPC: C30B29/36
Filed: 2013-12-06
Abstract: PROBLEM TO BE SOLVED: To provide high quality single crystal silicon carbide with less defects.SOLUTION: In a silicon carbide crystal growth method using a solution technique, a melting pot based on SiC is used as a storage section of Si-C solution. When the melting pot is heated, temperature distribution is generated in a manner that increases a temperature with an increasing depth of the Si-C solution from an upper side to a lower side thereof in the melting pot. Also, Si and C originated from the melting pot based on the SiC is eluted from a high temperature region on the surface of the melting pot where the same contacts the Si-C solution and thereby preventing polycrystalline SiC from generating on the surface of the melting pot where the same contacts the Si-C solution. With the silicon carbide solution kept in this state, the same is brought into contact with SiC seed crystals at an upper section thereof so as to allow single SiC crystals to be generated on the SiC seed crystals. By using the melting pot based on the SiC, the method curbs: a composition variation in the Si-C solution; precipitation of the polycrystalline SiC on an inner wall of the melting pot; and generation of metallic carbide formed when added metallic elements M combine with carbon C.
