    • A device for measuring a weft, particularly a drum type weft length measuring device for shuttleless looms is disclosed. The device is provided with a length measuring drum for coilingly winding a weft supplied from a weft supply bobbin and a pair of weft engaging pins for controlling a winding amount of the weft on the drum and a shift of the wound weft towards the weft drawing-out direction. The weft engaging pins are linearly movable in their own axial directions for protruding from and retracting into the drum, alternately. These protruding and retracting positions are shiftable in the axial direction of the drum.
    • 公开了一种用于测量纬纱的装置,特别是用于无梭织机的滚筒式纬线测量装置。 该装置设有长度测量滚筒,用于卷绕从纬纱供应线轴提供的纬纱和一对纬纱接合销,用于控制滚筒上的纬纱的卷绕量,并且绕纬纱向纬纱拉伸位移, 出方向。 纬纱接合销可以在其自己的轴向方向上线性移动,以便突出和退回到滚筒中。 这些突出和缩回位置可以在滚筒的轴向方向上移动。

    • In a multiple digital controller system which comprises a main or first digital controller and at least one stand-by or second digital controller and in which the main digital controller normally applies the control signal to an object to be controlled, and the stand-by digital controller applies the control signal to the controlled object when the main digital controller is disabled, an improvement is made so that an undesirable level variation may not substantially occur in the control signal applied to the controlled object during the transient state of switch-over from the main digital controller to the stand-by digital controller. In the improved multiple digital controller system according to the present invention, the integral calculation to be carried out in the stand-by digital controller in a period n (n=2, 3, . . . ) is executed on the basis of the data representing the result of integral calculation carried out in the preceding period (n-1) in the main digital controller and transmitted from the main digital controller, in order to eliminate the influence of the difference in conversion error occurring in the A/D converters of the digital controllers.

    • A damper for a stringed instrument has an elastic foldable web provided with catch members positioned at the end portions thereof, a hinge portion positioned at the longitudinally central portion thereof and notches of substantially isosceles triangular shape disposed close to and outwardly from the hinge portion. On the inner surface of the foldable web a resilient spongy member is secured. When the foldable web is folded for holding the strings of a stringed instrument in between the upper and lower layers of the resilient spongy member and the catch members are fastened, the strings are compressed by the spongy member and the sounds produced from the strings may be lowered.
