    • A dental attachment is embedded in a denture base so as to attach to a keeper made of a soft magnetic material built in a tooth root by magnetic attractive force. The dental attachment comprises an attachment main body which has a magnetic body delivering magnetic attractive force and a cap which covers a head portion located on the opposite side of an attractive surface to attach the keeper of the attachment main body. The cap, made of a non-magnetic material, is installed in the attachment main body so as to be able to move between a contacting position (A) which contacts with the head portion and an extended position (B) which is far from the head portion for a certain distance.
    • 牙科附件被嵌入义齿底座中,以便通过磁力吸引力附接到由内置在牙根中的软磁性材料制成的保持器。 牙科附件包括具有提供磁吸引力的磁体的附接主体和覆盖位于吸引表面的相对侧上的头部的盖,以附接附件主体的保持器。 由非磁性材料制成的盖子安装在附件主体中,以能够在与头部接触的接触位置(A)和远离头部的延伸位置(B)之间移动。 头部一定距离。

    • A dental magnetic attachment having good cushioning properties against a compressing pressure which makes a denture sink appropriately on biting. The dental magnetic attachment embedded in the denture base for holding the denture in the oral cavity by a magnetic attractive force working with the magnetic assembly and a soft magnetic keeper embedded in the top of the root surface includes a magnetic assembly and a cap covering the top of the magnetic assembly. The magnetic assembly has a hollow in the center of its top. The cap with a button is placed on the magnetic assembly, inserting the button into the hollow to contact to its bottom. On biting, the button is compressed, to be deformed with a shorter thickness and at this time a sleeve formed as a body around the core slides down along the side of the magnetic assembly to reduce the thickness of the dental magnetic attachment. This sliding makes the denture sink uniformly and appropriately. The dental magnetic attachment has good cushioning properties and offers a good feeling to a patient when biting with the denture.
    • 牙科磁性附件具有抵抗压缩压力的良好缓冲性能,这使得义齿在咬合时适当地下沉。 嵌入在义齿基座中的牙科磁性附件通过与磁性组件一起工作的磁性吸引力和嵌入根表面顶部的软磁保持器将义齿保持在口腔中,包括磁性组件和覆盖顶部的帽 的磁性组件。 磁性组件在其顶部的中心具有中空部分。 带有按钮的盖子放置在磁性组件上,将按钮插入空腔中以接触其底部。 在咬住时,按钮被压缩,以更短的厚度变形,此时,作为主体围绕芯部形成的套筒沿着磁性组件的侧面向下滑动以减小牙齿磁性附件的厚度。 这种滑动使得义齿沉没均匀和适当。 牙齿磁性附件具有良好的缓冲性能,并且在与义齿咬合时对患者提供良好的感觉。

    • A tracking control system for an information reproducing apparatus employs a recording medium which has recorded therein a tracking signal including a pilot signal and a synchronizing signal. The tracking control system includes a synchronizing signal detection circuit which detects the synchronizing signal, a timing circuit which outputs a pulse delayed from a timing when the synchronizing signal has detected the synchronizing signal, an amplitude detecting circuit which obtains the amplitude of the pilot signal, a capacitor whose one terminal is connected to the amplitude detection circuit, a switching circuit whose one terminal is connected to the other terminal of the capacitor and whose other terminal thereof is fixed at a constant electrical potential, a switching control circuit which controls the switching of the switching circuit upon receiving the output of the synchronizing signal detection circuit, a sample/hold circuit which holds, upon receiving the pulse from the timing circuit, a voltage appearing at the connection point of the capacitor and the switching circuit. This held voltage is used as a tracking error signal.
    • 用于信息再现装置的跟踪控制系统采用其中记录有包括导频信号和同步信号的跟踪信号的记录介质。 跟踪控制系统包括检测同步信号的同步信号检测电路,输出从同步信号检测到同步信号的定时延迟的脉冲的定时电路,获取导频信号的幅度的振幅检测电路, 一个端子连接到振幅检测电路的电容器,一个端子连接到电容器的另一端并且其另一端固定在恒定电位的开关电路,控制开关控制电路 所述开关电路在接收到同步信号检测电路的输出时,采样/保持电路在接收到来自定时电路的脉冲时保持出现在电容器和开关电路的连接点处的电压。 该保持电压用作跟踪误差信号。
