摘要： An electric noise absorber comprising at least two ferrite pieces having abutting planes, at least two case members containing the ferrite pieces respectively and being closed by means of engagement members, and a spring member provided in at least one of the case members for pressing the ferrite pieces against each other when the case members are closed. Since the case members for keeping the ferrite pieces in appropriate positions and the spring member for pushing up the ferrite pieces for close contact are separately molded, the case members are bestowed with strength and the spring member with elasticity, both suitable for their own purposes. The case members requires no apertures for biasing members and therefore outside magnetic substance is prevented from contacting with the ferrite pieces contained in the case members.Another type of electric noise absorber comprising longitudinally divided pieces of magnetic substance shaped to surround the periphery of an electric cable when closed, and magnetic fluid applied to at least one of abutting planes of the divided pieces for securely contacting the abutting planes with each other. Even if the abutting planes are rough and/or are not exactly horizontal surfaces, the magnetic fluid allows the ferrite pieces to be closed with no gaps between them. Consequently, the ferrite pieces keep substantially as low impedance as that of a non-divided ferrite piece.
摘要翻译：一种电噪声抑制器，包括至少两个具有邻接平面的铁氧体片，至少两个壳体部件，分别包含铁氧体片，并且通过接合部件封闭;以及弹簧部件，设置在至少一个壳体部件中，用于将铁氧体当壳体构件关闭时，它们彼此相对。由于用于将铁氧体保持在适当位置的壳体构件和用于将铁氧体块推压紧密接触的弹簧构件被分开模制，所以壳体构件被赋予强度，并且弹性构件具有弹性，两者都适合于它们自己的目的。壳体部件不需要用于偏置部件的孔，因此防止外部磁性物质与包含在壳体部件中的铁氧体片接触。另一种类型的电噪声吸收器，包括纵向分割的磁性物质片，其形状在封闭时包围电缆的周边，并且磁性流体被施加到分割片的邻接平面中的至少一个，用于将邻接平面彼此牢固地接触。即使相邻的平面是粗糙的和/或不完全是水平的表面，磁性流体允许铁氧体块在它们之间没有间隙的情况下关闭。因此，铁氧体块的阻抗基本上与未分割铁氧体的阻抗基本相同。

摘要： This invention is a ferrite molding made by a manufacturing method of molding and sintering ferrite particles, which are made by pre-sintering of magnetic materials including iron oxide, together with metallic particles mixed therein by a hydrostatic pressing at extra-high pressure, whereby metal fills in between the ferrite particles. The ferrite molding has improved ductility so as to resist chipping and breaking and has extremely low hydroscopicity so as to maintain its characteristics.

An elastic packing pipe is provided by fitting in contact with the inner circumferential faces of the gripping pieces, and the clamping pipe is tapered about the inner circumferential face of an end portion thereof so that about the outer periphery of their top end portions, the gripping pieces can abut against and be pressed radially toward the center of the device by the tapered end portion of the clamping pipe. Also, means such as notches and/or projections directed opposite to the lead direction of the male screw of the cylindrical body are provided, by which the top end portions of gripping pieces and the tapered portion of the clamping pipe are mutually fixed. This locking device is advantageously used for locking a cable or the like to a fixing member such as a wall.

摘要： The conductive seal of the present invention comprises the conductive layer and the sealing member. The conductive layer is composed only for providing conductivity, and the sealing member is composed only for providing a sealing effect. The conductive layer is such a thin coat that the conductive seal as a whole has a sufficient sealing effect, when it is applied onto the housing. Owing to such a sufficient sealing effect, the conductive layer can be securely adhered to the housing. Consequently, the conductive seal protects the electronic equipment from electromagnetic waves and prevents electromagnetic waves generated by the electronic equipment from leaking outside. The conductive layer is so thin that manufacturing cost can be reduced even when silver powder or copper powder is used for the layer.

摘要： An electric noise absorber comprises an axially divided magnetic body having abutment surfaces, a first joint on which the divided magnetic body can swing, and a second joint having a resilient member. The end of a second joint is attached to one part of the divided magnetic body, and the other end of the second joint can be attached to or detached from the other part of the divided magnetic body. Since the second joint can be unlocked, the electric noise absorber can be easily attached around a desired position on the electric wire without disconnecting the electric wire. When the other end of the second joint is pulled and attached to the magnetic body using the contraction force of the resilient member, the abutment surfaces of the divided magnetic body are held closely adjacent to the electric wire, making a magnetic circuit about the electric wire. The electric noise absorber can thus absorb electric noise with a minimum required structure.
摘要翻译：电噪声吸收器包括具有邻接表面的轴向分开的磁体，分割磁体可摆动的第一接头和具有弹性构件的第二接头。第二关节的端部附接到分割磁体的一部分，并且第二关节的另一端可以附接到分割磁体的另一部分或从其分离的磁体的分离。由于第二接头可以被解锁，因此电噪声吸收器可以容易地安装在电线上的期望位置上而不断开电线。当第二关节的另一端使用弹性构件的收缩力拉动并附接到磁体时，分割的磁体的邻接表面紧紧地保持在电线附近，从而形成围绕电线的磁路。因此，电噪声吸收器可以以最小的所需结构吸收电噪声。
