    摘要： A tongue plate stopper has a first disc having its webbing side face formed with at least one needle to be inserted through a webbing; and a second disc having a fitting portion for fitting the needle therein. At least one of the first and second discs has its webbing side face formed with a plurality of pins for biting into the webbing. The needle of the first disc projects from the central portion thereof. The fitting portion of the second disc has a hole. The pins include a first set of pins projecting from the circumferential edge of the back face thereof and at a circumferential spacing from one another, and a second set of pins projecting from the middle portion between the needle and the circumferential edge and at a circumferential spacing from one another. The second disc has its webbing side face formed with a first circumferential groove, which extends in the circumferential direction at a radius substantially equal to that of the first set of pins, and a second circumferential groove which extend in the circumferential direction at a radius substantially equal to that of the second set of pins, so that the first set of pins can have their tips engaging with the first circumferential groove whereas the second set of pins can have their tips engaging with the second circumferential groove.

    摘要翻译： 舌板止动器具有第一盘，其第一盘的带状侧面形成有至少一个针穿过织带插入; 以及具有用于将针安装在其中的装配部分的第二盘。 第一和第二盘中的至少一个具有其带状侧面形成有用于咬入织带的多个销。 第一盘的针从其中心部突出。 第二盘的装配部分具有孔。 销包括从其背面的周缘突出并且彼此以圆周间隔突出的第一组销，以及第二组销，其从针和周缘之间的中间部分突出并且周向间隔 从彼此。 第二盘的带状侧面形成有第一周向槽，该第一周向槽沿圆周方向以与第一组销的大致相等的半径延伸;第二周向槽，其沿圆周方向以大体上的半径 等于第二组销的第一组，使得第一组销可以使其尖端与第一周向槽接合，而第二组销可以使其尖端与第二周向槽啮合。

    摘要： An automatic lapping apparatus for lapping a piezoelectric material has upper and lower lapping plates, and a carrier disposed between the plates, for holding a piezoelectric material so that it is sandwiched between the plates. The carrier is rotatable to lap the piezoelectric material parallel to the lapping surfaces of the plates while supplying a lapping slurry therebetween. The apparatus also includes a sweep oscillator for applying a sweep signal corresponding to the count of a counter, through an AGC amplifier and a resistor to an electrode supported by one of the plates, a comparing circuit for determining whether the quartz crystal wafer is present underneath the electrode based on the level of the sweep signal applied to the electrode, a memory for storing output data from the comparing circuit at an address corresponding to the count, a dip detector for detecting a dip in the signal applied to the electrode and stopping operation of the counter, a frequency detector for reading the frequency from the sweep oscillator when the dip is detected and the presence of the piezoelectric material underneath the electrode is detected, a frequency determining circuit for determining whether the read frequency is a true resonant frequency of the quartz crystal wafer, a frequency comparator for determining that lapping is completed when the true resonant frequency falls within a predetermined target frequency, and an drive unit control circuit for stopping the carrier when the lapping is completed.
