    • A threading unit for threading a thread through holes of a sheet-like flat member, including an upper block (2) and a lower block (3) mating with each other and each having formed therein a discontinuous vessel having apertures open on the respective mating surfaces. The upper and lower blocks, when joined together, have their discontinuous vessels connected to each other to complete a continuous vessel through which a thread is threaded. The upper and lower blocks are each split into a first upper piece (2A) and a second upper piece (2B) and a first lower piece (3A) and a second lower piece (3B), respectively, along the parting face. Each split has on its parting face a lengthwise cut half of the discontinuous vessel. The sheet-like flat member is sandwiched between the mating faces of the upper and lower blocks (2) and (3) with its holes coinciding with the apertures of the upper and lower blocks.
    • 一种用于将线穿过片状平坦部件的孔的穿线单元,包括彼此配合的上部块(2)和下部块(3),并且每个都形成有不连续的容器,该不连续的容器在相应的配合 表面。 上下块在连接在一起时具有彼此连接的不连续的容器,从而完成一个连续的容器,螺纹穿过该容器。 上下块分别沿着分型面分别分为第一上部件(2A)和第二上部件(2B)以及第一下部件(3A)和第二下部件(3B)。 每个裂口在其分开的表面上具有不连续血管的纵向切割半部。 片状平板部件被夹在上下块(2)和(3)的配合面之间,其孔与上部和下部块的孔重合。

    • This invention provides a digital broadcasting receiving unit capable of achieving synchronization of time information between a base station and a receiving unit with reference clock without use of a crystal oscillator (VCXO) having a variable frequency. The crystal oscillator oscillates a clock of a predetermined fixed frequency. A variable digital dividing circuit divides a fixed frequency by a division ratio so as to change the division ratio. A system decoder detects reference time information from the base station. A reference counter generates time information of a receiving unit. A phase comparator detects a difference between reference time information and time information. A division ratio control circuit controls the change of the division ratio based on the difference. The reference counter generates time information based on a clock having a frequency obtained by dividing by the variable digital dividing circuit and feeds back time information to the phase comparator.
    • 本发明提供一种数字广播接收单元,其能够在不使用具有可变频率的晶体振荡器(VCXO)的基准时钟的情况下实现基站与接收单元之间的时间信息的同步。 晶体振荡器振荡预定固定频率的时钟。 可变数字分频电路将固定频率除以分频比以改变分频比。 系统解码器从基站检测参考时间信息。 参考计数器产生接收单元的时间信息。 相位比较器检测参考时间信息和时间信息之间的差异。 分频比控制电路基于该差异来控制分频比的变化。 参考计数器基于具有通过可变数字分频电路除以获得的频率的时钟产生时间信息,并将时间信息反馈到相位比较器。
