Motion synchronization between tool in X direction and principal axis rotation was controlled by electronic gearbox in cam turning. And profiling mechanism could be superseded by servo tool-holder. Linear motor direct drive servo tool-holder was designed, and host-slave control system with PC and DSP was developed for the require of high-speed and realtime servo. The technical process was analyzed in cam turning. Servo tool holder with tool swinging and principal axis variable rotate speed were presented to keep constant cutting angle and speed.

将电子齿轮箱用于凸轮车削加工系统的传动，以伺服刀架取代了传统加工的靠模装置，实现了刀具X方向直线运动与机床主轴转动的同步控制；设计了直线电机直接驱动的伺服刀架及基于PC与DSP构成的上—下位机控制结构，采用DSP进行实时控制以满足高速伺服需要；对凸轮加工过程的工艺特点与恒角度、恒速度车削进行研究，提出了具有刀具摆动功能的伺服刀架与机床主轴变转速运动方案。

E-CIGARETTES: Electronics company Ruyan of Beijing, China, has come up with a battery-powered electronic device that delivers nicotine when you puff on it.

Chen rui1,zhou shu-min2(east china institute of technology, 344000 fuzhou, china)abstract: radon chamber is a standard equipment which demarcates radon measure instrument. this paper introduces a high- speed data acquisition card called pci- 8408 based on pci bus, and data collection is controlled automatically by device driver using mcgs.

氡室作为刻度测氡仪器的一种标准装置有着重要的应用，本文利用pci-8408光隔离开关量输入输出接口卡作为数据采集接口，根据采集数据对氡室气路进行控制，并通过mcgs组态软件以设备驱动程序的方式控制继电器的状态，实现氡的自动补给和排放以及氡室内温湿度的智能控制。

Based on theory of structural dynamics and differential equation, the requirement of state complete observability is infered related to vibration modes, which is more acceptable for engineering than the counterpart of modern control theory related to rank of matrix in algebra.

这一条件较之现代控制理论中以矩阵秩的形式给出的相应条件更易为工程实际所接受，对测量装置的位置设置提供了理论依据，并指出无干扰驱动项的经典的Luenberger观测器对结构控制是不适宜的。

According to the characteristic of 3-D loom in existence, leading-yarn needle and crochet hook is designed in the selvedge apparatus to realize the selvedge by using the knitting method. They are all driven by high pressure air cylinders with different models, which are chosen based on the demand of various moving parts. The apparatus element is controlled by electromagnetic valve, so it can syncretize very well with the loom.

根据现有织机机构特点，边部机构中设计了引纱针与钩边针配合运动来实现针织锁边，这两部分装置都采用气动驱动，气缸型号根据机构的要求和条件选择，执行元件均由电磁阀控制，与织机整体很好地融合在一起。
