Development of cell line mechanism

用音圈马达振动一个装有卵子和培养基的方形盒子，目的是将这些卵子聚集在盒子的中心。其次，用图像处理装置选取符合所记忆形状的卵细胞，逐一定位于持液点。通过试验，构建了具有上述功能的系统。该系统可以自动定位任意卵子在固定位置，从而缩短了寻找卵子并将其定位到持液点的时间。预定位部分研制了用音圈马达摇动培养皿和装满介质的方盒的装置。音圈电机由模拟PID控制器控制，该控制器将变送器输出的电压与涡流间隙传感器检测到的位移电压进行比较。小方盒固定在安装在音圈电机轴线上的大方盒内。发射机输入电压波，控制音圈电机，摇晃方盒。这种振动被用来收集卵子。

A square case containing ova and culture medium was vibrated using a voice coil motor on purpose to gather those ova at the center of the mentioned case. Followed by, only those ova which conform to the memorized shape are selected with a picture processing device and are positioned at the point of holding pipette one by one. A system with mentioned functions was constructed on trial.This system can position automatically any ovum at the fixed position, and therefore could shorten the time of the process to search out the ovum and position it at the point of holding pipette.Prepositioning partThe device which shakes the Petri dish and square case filled with medium by using a voice coil motor was made for trial purposes. The voice coil motor is controlled by analog PID controller which compares the voltage from the transmitter with the displacement voltage detected by the eddy current gap sensor. The small square case is fixed in a large square case installed at the axis of the voice coil motor. A voltage wave is inputted by the transmitter to control the voice coil motor, and the square case is shaken. This vibration is used to gather the ova.
