    摘要: An amorphous alloy-based magnetic core with reduced audible noise and a method of making the amorphous alloy-based magnetic core emanating low audible noise, including: placing the core with multiple layers of high strength tape on the core legs, wherein the tapes have a high tensile strength, high dielectric strength and high service temperature, resulting in reduced level of audible noise. When operated under optimum condition, the reduced level of audible noise is 6-10 dB less when compared with a same-size core that has been coated with resin instead.

    摘要: A magnetic implement has a gap size ranging from about 1 to about 20 mm. The implement comprises a magnetic core composed of an amorphous Fe-based alloy. A physical gap is disposed in the core's magnetic path. The alloy has an amorphous structure; is based on the components: (Fe—Ni—Co)—(B—Si—C). The sum of its Fe+Ni+Co content is in the range of 65–85 atom percent. Advantageously, the core exhibits an overall magnetic permeability ranging from about 40 to about 200 and enhanced magnetic performance.

    摘要: Electronic article surveillance markers, methods for their production and for their use are disclosed. In one aspect there is provided an integrated deactivatable hybrid marker which can be used both in radio frequency and magnetic harmonic article surveillance systems. The harmonics generating element or elements of the marker are inserted into a RF resonant circuit as an active part of the circuit. The deactivation of the marker is accomplished by employing another element of high coercivity magnetic material. When placed in a RF interrogation field, the hybrid marker causes an increase in absorption of transmitted signal in order to reduce the signal in the receiving coil of the RF surveillance system. When placed in an interrogation zone of a magnetic harmonic article surveillance system, the marker generates high harmonics of the interrogating frequency that can be detected by the receiver of the surveillance system. In addition both the RF and harmonic functions of the hybrid marker can be deactivated by a single process. Further more, the use of conductive paste material to print the RF circuits is disclosed to achieve a low cost manufacturing process.

    摘要: Metallic glasses having high permeability, low coercivity, low ac core loss, low exciting power, and high thermal stability are disclosed. The metallic glasses are substantially completely glassy and consist essentially of about 71 to 79 atom percent iron, about 1 to 6 atom percent of at least one member selected from the group consisting of chromium, molybdenum, tungsten, vanadium, niobium, tantalum, titanium, zirconium and hafnium, about 12 to 24 atom percent boron, about 1 to 8 atom percent silicon, 0 to about 2 atom percent carbon, plus incidental impurities, the total of boron, silicon and carbon present ranging from about 18 to 28 atom percent. The alloy is heated treated at a temperature and for a time sufficient to achieve stress relief without inducing precipitation of discrete particles therein. Such a metallic glass alloy is especially suited for use in devices requiring high response to weak magnetic fields, such as ground fault interruptors and current/potential transformers.
