摘要： PURPOSE:To obtain an aluminum alloy wire having high bonding strength and high corrosion-resisting property by a method wherein the second noble element having no solubility for Al and the third element having solubility for Al are contained in Al. CONSTITUTION:In order to improve the corrosion-resisting property of a corrosion-resisting Al alloy wire, the second noble element having no substantial solubility for Al is contained in Al. The second element consists of one or two kinds selected from the group of Au, Ni and Pd. Also, the third element having solubility for Al is added for the purpose of increasing the degree of hardness of a ball without impairing the corrosion-resisting property of the corrosion- resisting Al alloy wire. Said third element is the element which is selected from the group of Cu, Mg, Ti and Zr. As a result, the corrosion-resisting Al alloy wire having the hardness of Hv30 or above in the ball hardness in normal temperature can be obtained. Accordingly, high bonding strength and a high corrosion-resisting property can be obtained.

摘要： PURPOSE:To prepare a maraging rotor excellent in toughness, by successively applying spinning processing, heat treatment, spinning processing and ageing treatment to maraging steel comprising a specific composition after solution heat- treatment under a specific condition. CONSTITUTION:Solution heat-treatment is applied to 245kg/mm. -grade maraging steel containing, on a wt. basis, 17-19% Ni, 12-13% Co, 3.5-4.5% Mo, 1.6- 1.75% Ti and 0.05-0.15% Al and comprising the remainder of iron and impurities at about 800-850 deg.C for about 1-2hr. Subsequently, spinning processing is performed in a thickness reducing ratio of 20% or more at 200 deg.C or less and heat treatment is applied at 760-820 deg.C. Further, spinning processing is performed in a thickness reducing ratio ranging from 55-80% and, thereafter, ageing treatment is performed at about 460-540 deg.C for about 1-24hr. By this method, a maraging rotor which is reinforced to a degree of 255-270kgf/mm. and can be used without anxiety is obtained.

摘要： PURPOSE:To increased the precision of measurement of the transformation ratio by comparing the primary and secondary side DC voltages of the transformer with a null method using a voltage comparator circuit. CONSTITUTION:A DC voltage M1 proportional to the primary side DC input to a transformer 5 for a DC measuring instrument and a DC voltage M2 proportional to the secondary side output are obtained, and one of these DC voltages and a DC voltage taken out from the other voltage through a voltage divider consisiting of resistors 9b and 9g are compared with a voltage comparator circuit 9a for obtaining the transformation ratio of the transformer from the resistance ratio of the voltage divider by making both the DC voltages equal. In this way, precise measurement of the transformation ratio of the transformer can be obtained by comparing the primary and secondary side DC voltages of the transformer with a null method using a voltage comparator circuit and deriving the transformation ratio of the transformer from the resistance ratio of the voltage divider at that time.
