摘要： An apparatus for assembling a repelling magnet combination, comprising a first and second magnet, a first and second holding magnet, a first holding base with a first holding base first end, and a second holding base with a second holding base first end. The first and second holding magnets are positioned at the first and second holding base first ends, and the first and second magnets are magnetically attached to the first and second holding magnets respectively, with outward faces exhibiting like magnetic polarities. The first and second magnets are brought into contact by moving the first and second holding base first ends into close proximity, whereby the first and second holding magnets exert holding forces on the first and second magnets which overcome a repelling force generated therebetween, allowing a repelling force countering means, such as an adhesive, to bond the magnets together into a repelling magnet combination.

摘要： The magnetic bearings make use of magnet assemblies with a high magnetic field gradient. The magnet assemblies use two permanent magnets with opposite polarisation in a Kittel open domain structure. The basic factor of magnetic separation is the magnetic force, which acts on a particle of the substance and which is proportional to the magnetic susceptibility of the substance, the value of the magnetic induction B and the value of the gradient ∇B of the applied magnetic field. Therefore, increasing the sensitivity and selectivity of magnetic separation will require use of the highest possible values of magnetic induction B and magnetic field gradient ∇B, or their united factor—the product B∇B. The magnetic assembly have repulsive magnetic systems each having two juxtaposed permanent magnets 2, 4 with opposite magnetization in the form of a Kittel open domain structure. In such an system, near the edges of the faces of the joining magnets, a strong magnetic stray field appears and the value of the product B∇B reaches 1011 mT2/m. To concentrate the magnetic stray field shields 6 are provided on top of the two magnets 2,4 with a gap 8 between the shields at the joint of the two magnets 2, 4 forming zones of high magnetic field gradient 14 with increased magnitude for the product B∇B.

摘要： A Neodymium-Iron-Boron permanent magnet which is substantially wider across a first axis than across the perpendicular second axis. The second axis is the axis defining the north and south poles of the magnet. At one of the poles is a permalloy cap which is substantially parallel to the first axis and inhibits the extension of magnetic flux from that pole and encourages instead a deep extension of the magnetic flux from the other pole. An aperture penetrates the magnet through the second axis which is wider at the pole away from the permalloy cap than it is at the pole adjacent to the permalloy cap. The shape of this aperture causes a distortion of the deeply extending magnetic flux lines at the pole away from the permalloy cap to be pinched inward toward the second axis rather than being parallel to it. The magnet thus provides a concentrated magnetic force that extends deeply out of its base so that the magnet can be placed on the exterior of a vessel or conduit with the result that the fluid inside is treated with optimized magnetic force.
摘要翻译： 钕铁硼永磁体，其在第一轴线上比横过垂直第二轴线基本上更宽。 第二轴是定义磁体的北极和南极的轴线。 其中一个极点是坡莫合金盖，其基本上平行于第一轴线并且阻止来自该极的磁通量的延伸，并且鼓励来自另一个极的磁通的深度延伸。 光圈穿过第二轴线，该第二轴线远离坡莫合金盖杆的距离比在坡莫合金盖板附近的极板处更宽。 该孔的形状导致远离坡莫合金盖的极的深度延伸的磁通线的变形被向内朝向第二轴线夹紧，而不是平行于其。 因此，磁体提供了从其底部深深延伸的集中磁力，使得磁体可以放置在容器或管道的外部，结果是内部的流体被优化的磁力处理。

摘要： A developing roller (1) includes a highly conductive shaft (2) and a conductive elastic layer (3). When the developing roller carring a one-component developer thereon comes in contact with or in proximity to an image forming body, the developer is supplied from the roller to a surface of the image forming body, thereby forming a visible image on the image forming body surface. The elastic layer (3) has applied to its surface a resin component having an elongation at rupture of less than 10% as measured according to JIS K7113. The developing roller ensures that images of high quality are reproduced without a drop of image density over a long period of time.
