    • There will be provided a punching unit capable of reliably drawing a punch out of the workpiece, improving the productivity and without deteriorating the boring precision even for a workpiece which easily spreads, and preventing leavings rising. A stripper plates which has been positioned close to the workpiece in accordance with the thickness thereof does not press the workpiece, but draws the punch during rising out of the workpiece to transmit the striking driving force of the electric motor to the movable die holding the punch. In an air path portion arranged within the machine frame, there is provided means for opening or closing through an electric signal and the air path between the air ejecting unit and the means is made shorter, whereby the response to air ejection is improved, the pressure loss during air flow is reduced to a minimum, and jet air is accurately applied to punching chips (leavings) which adhere to the punch at the bottom dead center for peeling off the punch.
    • 将提供一种能够可靠地从工件中拉出冲头的冲压单元,即使对于容易扩散的工件也能够提高生产率并且不会降低镗孔精度,并且防止上升。 已经根据其厚度定位在工件附近的剥离板不会挤压工件,而是在从工件上升期间拉出冲头以将电动机的冲击驱动力传递到保持冲头的可动模具 。 在设置在机架内的空气路径部分中,设置有用于通过电信号打开或关闭的装置,并且使空气喷射单元和装置之间的空气通道变短,由此提高对空气喷射的响应,压力 气流中的损失减少到最小,并且喷射空气被精确地施加到冲压在下死点处的冲头的切屑(离开),以剥离冲头。

    • A flasher type fish sonar includes a case, a circuit board mounted in the case, and a motor attached to the circuit board and including a rotary shaft. A light conducting disk is fixed to the rotary shaft and includes a projecting portion for mounting the light conducting disk, a luminous portion and a light conducting portion for conducting light to the luminous portion. A shadow disk is fixed to the luminous portion and includes a slit through which light passes from the luminous portion. A front display disk is provided in front of the shadow disk. A luminous element is connected with the circuit board opposite to the light conducting portion. A fish sonar circuit inputs signals of a surface of a body of water, fish, and a bottom of the water, and a piezoelectric vibrator is connected to the fish sonar.
    • 闪光型鱼声包括壳体,安装在壳体中的电路板,以及附接到电路板并包括旋转轴的电动机。 导光盘固定在旋转轴上,包括用于安装导光盘的突出部分,用于将光传导到发光部分的发光部分和导光部分。 影子盘固定在发光部分上,并且包括一个光线从发光部分穿过的狭缝。 在影子盘的前方设有前显示盘。 发光元件与电路板与导光部相对。 鱼声纳电路输入水,鱼和水底部的表面的信号,并将压电振动器连接到鱼声呐上。
