Title: Heat processing method of amorphous wound magnetic core
Inventor: YOSHIZAWA KATSUTO
IPC: H01F41/02
Filed: 1984-02-15
Abstract: PURPOSE:To supress fluctuation of magnetic characteristics and obtain a wound magnetic core having good characteristics by executing heat processing at temperature lower than the Curie point by giving magnetic field in the direction orthogonal to the magnetic path of amorphous wound magnetic core and thereafter executing similar heat processing by giving magnetic field in the direction of magnetic path. CONSTITUTION:Heat processing under magnetic field is carried out by appling the magnetic field orthogonal to the magnetic path of wound magnetic core and magnetic anisotropy is made small by giving magnetic anisotropy in the orthogonal direction to the magnetic path. Thereafter, a heat processing under the magnetic field is carried out by appling magnetic field in the direction of magnetic path. Thereby, the axis of easy magnetization is rotated and heat processing is carried out by raising a square ratio up to an adequate value. Namely, while the wound iron core is set higher than the Curie temperature but lower than the crystallization temperature before the heat processing under the magnetic field for the heat processing and thereafter it is cooled suddently. Thereby, dispersion of magnetic anisotropy during manufacture of ribbon can be reduced up to a certain degree. Moreover, in the case of giving anisotropy by applying magnetic field in the orthogonal direction the magnetic path, the axis of easy magnetization can be arranged only with giving a weak magnetic anisotropy and anisotropy is little dispersed.

Filed: 1990-02-06
Abstract: PURPOSE:To detect an internal ground fault failure with a high sensitivity by a method wherein the phase of a zero-phase difference current and the phase of a zero-phase voltage in the protected section of a distribution line are detected and, if the zero-phase difference current is within a certain range and the phase of the zero-phase current leads the phase of the zero-phase voltage, the fault is judged to be internal. CONSTITUTION:Detected zero-phase voltage VO and zero-phase difference current SIGMAIO2 are inputted to a phase difference judging circuit 14 which judges whether the phase difference between the voltage VO and the difference current SIGMAIO2 is within a predetermined range or not. In this process, it is used as a reference for determining the predetermined range that, if a failure is internal, the phase of the zero-phase difference current SIGMAIO2 leads the phase of the zero-phase voltage VO about 90 degrees. The judgement result is inputted to a fault judging circuit 11 and the fault is judged to be internal under the conditions that a signal which shows that the zero-phase difference current SIGMAIO2 exceeds a predetermined level is inputted and, further, a signal which shows that the phase difference between the current and voltage is within the predetermined range and then tripping commands are outputted to switchgears 4.2 and 4.3.

Title: Method for simultaneously treating aluminum dross and metal-containing waste
Inventor: KOMODA SHUNSAKU
IPC: C22B7/00
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To attain the recovery of useful metals and the reduction (of the volume) in the amt. of waste by bringing aluminum dross and metallic oxides derived from metal-contg. waste into thermit reaction. SOLUTION: The content of Al in aluminum dross is preferably regulated to >=27 wt.%. Metallic components in metal-contg. waste such as plating sludge, ferrous scale or the like lie in the form of oxides for stably progressing thermit reaction. Thus, if required, the metallic waste is previously subjected to heating, dewatering and decomposing treatment to convert the metallic components into metallic oxides. The thermit reaction can be executed in accordance with the conventional method. Since the reaction products are approximately separated into the components large in the content of iron and nonferrous components by their cracking, they are subjected to magnetic separation to separate both components.  In particular, because of forming the reaction products large in the iron content into massive ones and facilitating their separation and recovery by the magnetic separation, at the time of the reaction, a fluorine compd. such as CaF2 is preferably added in advance.
