    • The invention relates to a denture attachment implanted on a dental plate so as to face a keeper (103) formed of a soft magnetic body and adapted to be attracted to the keeper (103) by a magnetic attracting force, said denture attachment comprising at least three plate-shaped yokes formed of a soft magnetic body, and two plate-shaped magnets with N-S poles extending in a thicknesswise direction. In this example, the denture attachment comprises a central yoke (10), a first magnet (1), a second magnet (2), a first lateral yoke (11) and a second lateral yoke (12). The first magnet (1) and second magnet (2), which are positioned on both sides of the central yoke (10), have a feature in that the same poles face each other. So, separate magnetic loops are formed for the respective magnets. With this novel arrangement, the denture attachment can display a great magnetic attracting force double that of a conventional one while presenting compactness required for denture attachments. Further, if both magnets (1, 2) are covered as a whole by covering those surfaces of both magnets (1, 2), which abut against the keeper (103), with spacers (21, 22) formed of non-magnetic bodies and covering those surfaces of both magnets (1, 2), which do not face the keeper (103), with a casing (3) similarly formed of a non-magnetic body, the denture attachment can be improved in corrosion resistance and abrasion resistance.
    • 本发明涉及一种植入牙板上的义齿附着物,以面对由软磁体形成的保持器(103),并且适于通过磁吸引力被吸引到保持器(103)上,所述假牙附件至少包括 由软磁体形成的三个板状轭铁和具有沿着厚度方向延伸的NS极的两个板状磁体。 在该示例中,义齿附件包括中心轭(10),第一磁体(1),第二磁体(2),第一横向磁轭(11)和第二侧磁轭(12)。 第一磁体(1)和第二磁体(2)位于中心磁轭(10)的两侧,具有这样的特征:相同磁极彼此面对。 因此,为相应的磁体形成单独的磁环。 通过这种新颖的布置,义齿附件可以显示出与常规的相同的极大的吸引力,同时具有义齿附着所需的紧凑性。 此外,如果通过覆盖由非磁性体形成的间隔物(21,22)覆盖与保持器(103)抵接的两个磁体(1,2)的那些表面,则两个磁体(1,2)整体被覆盖, 并且通过类似地由非磁性体形成的壳体(3)覆盖不面对保持器(103)的两个磁体(1,2)的表面,可以提高耐腐蚀性和耐磨性 。

    • A denture attachment is planted in a denture base in such a manner as to oppose a keeper (103) made of a soft magnetic substance, and clamped by the keeper (103) through magnetic attraction. The attachment comprises at least plate-like three yokes made of a soft magnetic substance and at least two plate-like magnets the N and S poles are oriented in the direction of the thickness of the attachment. In the drawing, the attachment comprises a center yoke (10), a first magnet (1), a second magnet (2), a first side yoke (11) and a second side yoke (12). The magnetic poles of the first and second magnet (1, 2) on both sides of the center yoke (10) are characteristically opposed to one another. Therefore, an independent magnetic loop is formed for each magnet. Because of this novel structure, the magnetic force is about twice stronger than conventional while the denture has a compactness required generally. Spacers (21 and 22) made of a non-magnetic substance may cover the surfaces of both magnets (1 and 2) in contact with the keeper (103), and a casing (3) made of a non-magnetic substance may cover the entire portion other than the surfaces in contact with the keeper so as to improve both corrosion resistance and wear resistance.
    • 义齿附件以与软磁性物质制成的保持器(103)相对的方式种植在假牙基座中,并由保持器(103)通过磁吸引力夹持。 该附件至少包括由软磁性物质制成的板状三个轭和至少两个板状磁体,N和S极在附件的厚度方向上定向。 在附图中,附件包括中心磁轭(10),第一磁体(1),第二磁体(2),第一侧磁轭(11)和第二侧磁轭(12)。 中心磁轭(10)两侧的第一和第二磁体(1,2)的磁极的特征是彼此相对。 因此,为每个磁体形成独立的磁环。 由于这种新颖的结构,磁力比常规磁力强大约两倍,而义齿具有通常所要求的紧凑性。 由非磁性物质制成的间隔物(21和22)可以覆盖与保持器(103)接触的两个磁体(1和2)的表面,并且由非磁性物质制成的壳体(3)可以覆盖 与保持器接触的表面以外的整个部分,以便提高耐腐蚀性和耐磨性。

    • PURPOSE:To make works for tightening bolts and nuts for setting the width of a form executable easily and quickly to anyone. CONSTITUTION:The title device is composed of two principal shafts 1 and 2. A nut holding part 1a is provided to one end of the shaft 1 and a turning force transmitting disk 4 is provided to the other end thereof. The central part of the shaft 1 is fixed to the inner ring of a bearing 5, and the outer ring of the bearing 5 is supported with a case 8 through a spring 6. The shaft 2 is connected to a motor 3, and a turning force transmitting disk 4 is provided to the front end of the shaft 2. By pushing the front end of male screw on a bolt onto a tapped hole of a nut that is placed on the nut holding part 1a, the shaft 1 starts turning with the two turning force transmitting disks 4 brought into contact with each other, and thereby the nut is screwed down to the bolt. As the bolt is pulled out of the shaft 1 after the nut is completely screwed down to the bolt, the shaft 1 is put back to its original position by force of the spring 6. By repeating the above-mentioned processes, works can be completed.
