Title: Manufacture of extra fine sn-plated wire
Inventor: DOI SEIICHI
IPC: C22F1/08
Filed: 1988-11-15
Abstract: PURPOSE:To manufacture the title Sn-plated extra fine Cu wire without disconnection by subjecting a Cu wire or a Cu alloy wire having large diameter of specific one or above to hot dip Sn coating and subjecting it to wire drawing at the time of manufacturing an Sn-plated Cu wire having extra fine diameter. CONSTITUTION:At the time of manufacturing an extra fine Sn-plated wire having <=0.05mm wire diameter, a Cu wire or a Cu alloy wire having >=0.08mm diameter is passed through molten Sn to form an alloy layer of Sn and Cu of epsilon phase, eta phase or the like on the surface, and a pure Sn-plated layer having 0.05mum thickness is formed thereon. The Sn-plated Cu wire is subjected to wire drawing into an Sn-plated Cu wire having <=0.5mm of desired diameter. Since the diameter of the Cu or Cu alloy wire before the wire drawing is large one of >=0.08mm, disconnection caused by molten Sn does not occur during the coating operation, and by the wire drawing after that, the Sn-plated Cu wire having <=0.05mm diameter can be obtd.

Abstract: PROBLEM TO BE SOLVED: To prevent a mixture of noises by preparing a high frequency noise elimination coil of small floating capacitance at the input part of a voice amplifier circuit or the connecting part between an electronic device and every line that is led to the outside from the electronic device or at each of both parts. SOLUTION: An air core coil 14 is put into the connecting part between an electronic device and every line that is led to the outside from the electronic device. The coil 14 has about the impedance of 500Ω per GHz with a wire diameter of 35 μm, number of turns of 12, a floating capacitance of 0.3 pF, and an inductance of 100 nH respectively. Furthermore, the coil 14 has small inter-line floating capacitance with its wire formed into a single layer or wound in a single layer in a space. At the same time, a core 15 is molded from aluminum of ε set at 10 or less with the floating capacity set at 0.3 pH between the electrodes 17a and 17b.  Thus, the high frequency noises of several GHz mixed into the electronic device or other high frequency noises mixed via a power line connected to a circuit board and every line that is led to the outside from the circuit board can be eliminated. Under such conditions, the best floating capacity is 0 between both electrodes 17a and 17b. Although, this capacitance is best valve at 0, since this is impossible they are set at least at 0.1 to 0.2 pF.

Abstract: PURPOSE:To make an accident current speedily detectable, by making a DC breaker generate an open command at a time when the sum total of a variation in the secondary current taken in a DC current relay of a DC electric railway and a current variation portion of a feeder circuit holding a section in between goes beyond the setting value. CONSTITUTION:A DC current of a DC circuit (primary circuit) 21 is converted into an input signal via a current transformer 22 and taken into an input unit 23, then this taken DC current is processed in conformity with the program stored in a memory 25. A central processing unit 24 judges whether a variation in the DC current is more than the setting value or not, and when it is more than the setting value, an increment portion of the DC current from that point that the said variation is varied to the plus side is operated by the central processing unit 24. And, it also judges whether this increment value goes beyond the setting value or not, and when it exceeded the setting value, an open command is outputted to a DC breaker 20 from an output unit 26. And, supposing that the said increment value exceeds the setting value, if the total sum of the current increment portion of a feeder circuit holding a section in between is smaller, the open command is not outputted.
