摘要： PROBLEM TO BE SOLVED: To provide a solder erosion resistant member which exhibits high erosion resistance even to lead-free solder and realizes a long life.
SOLUTION: A dense amorphous metal (alloy) film is formed as a contact surface with molten solder or as a ground layer of the contact surface with molten solder. It is preferable that the thickness of the film is 0.01 mm or thicker. The amorphous metal (alloy) preferably contains 30 to 80 atm% of ferrous substance, particularly preferably metallic glass. The film can be formed by high-speed flame spray. Because of the highly erosion-resistant amorphous film densely formed on the contact surface of with molten solder, even when used in lead-free solder, the member suffers from only very little attack at a high temperature and can therefore achieves a markedly prolonged life.

摘要： PROBLEM TO BE SOLVED: To provide a composite material in which a compact metallic spray-coating layer is firmly deposited on a surface of an extremely thin metal substrate without breaking the metal substrate.SOLUTION: In the metallic glass composite material, the metallic glass spray-coating layer with no throughhole (pinhole) is formed on the surface of the metal substrate with a thickness of 5-300 μm without breaking the metal substrate. The metallic glass spray-coating layer is formed by heating at least a portion of a metal glass powder until it reaches a supercooled liquid state and solidifying and laminating the same on the surface of the metal substrate at a particle velocity of ≥300 m/s by thermal spraying. The supercooled liquid temperature range ΔTx of the metallic glass is ≥30°C, and the glass transition temperature Tg is ≤500°C. A pressurizing treatment of the metallic glass spray-coating layer at a supercooled liquid state can improve adhesion, denseness and homogeneity of the layer.

摘要： PROBLEM TO BE SOLVED: To provide an inductor whose loss is lower than that of conventional one and which can be manufactured by low-pressure molding. SOLUTION: In the three-dimensional shape of an amorphous soft magnetic powder particle used for manufacturing the inductor, the average value of the practical sphericity of Wadell is 0.90 or larger. This results from an effect that a higher average value of the practical sphericity of Wadell allows the suppression of the number of contact between powder particles in using the amorphous soft magnetic powder particles in a powder compacting body such as the inductor, and allows a higher density of filling when in pressure-forming, thereby raising powder compacting density and permeability. Moreover, this results from an effect that the suppression of the number of contacts between powder particles allows the manufacturing of the inductors or the like by low-pressure forming. Moreover, it is preferable to manufacture the amorphous soft magnetic powder particles of this embodiment by a water atomizing method. The reason is that the manufactured amorphous soft magnetic powder particle is easy to be shaped into a true sphere. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：提供损耗低于常规电感器的电感器，其可以通过低压成型制造。解决方案：在用于制造电感器的无定形软磁粉末颗粒的三维形状中，Wadell的实际球形度的平均值为0.90或更大。这是由于Wadell的实际球形度的较高的平均值能够抑制粉末颗粒在电感器等粉末压实体中使用无定形软磁性粉末颗粒的接触次数的效果，并且允许更高的密度在压力成形时填充，从而提高粉末压实密度和渗透性。此外，这是由抑制粉末颗粒之间的接触数量的效果导致通过低压成形制造电感器等。此外，优选通过水雾化法制造本实施方式的无定形软磁性粉末颗粒。原因是制造的非晶软磁粉末颗粒容易成形为真实的球体。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To solve such problem as that since a meso-scopic metallic cluster is different in catalyst, electron, photo-electron, magnetic characteristic, with a bulky metal, caused by the effect of comparative large surface area and few atomic number, this meso-scopic metal cluster is expected to the future development, but this scale is accumulated by making small into nano-meter size and further, is necessary to operate in the room temperature, and thus, crystal metal or alloy manufacturing method with the conventional mechanical or thermal cutting method, chemical-physical vapor-deposition coating method or corrosion method, can be not used. SOLUTION: An integrated fine structure (cell) which performs supper-fine patterning or quantum dot-tunneling, is manufactured with a manufacturing method for the metal or the alloy having nano-crystal by utilizing amorphous/crystal transition in the room temperature and by selectively melting the compositional elements in a metallic glass or metallic amorphous in the acidic solution without adding the outer energy, such as heat, light, electric charge.

摘要： PROBLEM TO BE SOLVED: To simply and inexpensively achieve a high recording density. SOLUTION: A nonmagnetic underlayer 42 and a soft magnetic metallic glass layer 44, which are provided on the top surface of a substrate 110, keep a structure similar to that of an amorphous without crystallizing even when subjected to heating and cold removal in thermal-type imprinting. Accordingly, a pattern can be formed in the soft magnetic metallic glass layer 44 by thermal imprinting without thermal effect to the layers. A hard magnetic layer 46 is divided and formed according to the formed pattern, thereby the pattern is formed without processing such as etching, ashing (that is without preparing equipment for the processing).
