摘要： A low core loss grain-oriented electrical steel sheet that does not have a significant deterioration in a magnetic flux density and a decrease of a space factor, and which may withstand stress-relieving annealing is provided. Melted and re-solidified layers can be formed on either or both of the surfaces of the grain-oriented electrical steel sheet that extend in a direction that is perpendicular to the rolling direction (e.g., in the direction of the width thereof), at a cyclic interval of not less than approximately 2 mm to less than approximately 5 mm in the rolling direction. The melted and re-solidified layers may be provided on each surface of the grain-oriented electrical steel sheet, and can have an aspect ratio that is a ratio of the depth to the width of the melted and re-solidified layer of not less than approximately 0.20 and a depth of not less than approximately 15 nullm. In addition, the melted and re-solidified layers can be formed by using a laser.

摘要： The abutted face plates of frame members are joined using friction stir welding. Next, a connection member is mounted on seats formed in the frame members, while a projection of one end of the connection member is inserted into a groove of an end portion of a face plate of the frame member. Next, the other end of the connection member is temporarily welded to the face plate of the hollow frame member. With this condition, an abutted portion of the face plate and the connection member are joined using friction stir welding. Then, the overlapped portion between the other end of the connection member and the frame member is joined by friction stir welding. When the hollow frame members are welded from one side, a temporary welding of the connection member can be reduced.

摘要： In an electronic device comprising a first electrodes consisting of a metal oxide and a second electrode consisting of an aluminum alloy film directly contacted and electrically connected to the first electrode, the contact interface between the aluminum alloy film and the first electrode is constructed so that at least a part of alloy components constituting the aluminum alloy film exist as a precipitate or concentrated layer. This construction enables direct contact between the aluminum alloy film and the electrode consisting of a metallic oxide and allows elimination of a barrier metal in such an electronic device, and manufacturing technology therefor.

摘要： In a method of producing a strip suitable for further processing to yield a (110)null001null grain oriented electrical steel from a thin strip such as a continuously cast thin strip the thin cast strip is processed to promote recrystallization from the surface layer of the strip (Snull0) into the quarter thickness of the strip (Snull0.2 to 0.3). The process parameters are selected so that the strain/recrystallization parameter(K*)null1, nullabout 6500 and wherein, 1 ( K * ) - 1 = ( T HBA ) null ln null [ e . 015 null exp null ( 7616 T HR ) null ln null ( t c t f ) ] THBA is the annealing temperature of the strip (in null Kelvin), THR is the hot rolling temperature of the strip (in null Kelvin), {dot over (null)} is the strain rate of hot rolling, ti is the initial thickness of the strip before hot rolling, and tf is the final thickness of the strip after hot rolling.
