Analysis of the controlled circuit of the paper running spead for ecg 6511 electrocardiogram instrument 6511型心电图机走纸速度控制电路的分析
A control mechanism for a typewriter or other listing device that can automatically control the feeding , spacing , skipping and ejecting of paper or preprinted forms 打字机或其它打印设备的控制机构,能自动控制走纸、空格、跳格以及弹出打印纸或表格纸。
In order to be successful in digital packaging printing , it is important to gain knowledge of the interaction between the substrate and the press 为了能成功地在卡纸上进行数字印刷,研究卡纸材料的印刷走纸性能、着墨性能和印刷质量,了解卡纸的表面性能与印刷之间的关系是卡纸数字印刷技术面临的首要问题。
At last the system composed of walking paper platform , dsp and personal computer is completed . a great number of experiments show that the design is successful , which has very good application value and market benefit 最后把走纸平台、 dsp系统、计算机连接成一个开发系统,通过大量的试验表明:系统的设计是成功的,并有很好的应用价值和市场效益。
Secondly , the interface and coordination of time order are analyzed in light of the principle of ccd . the image data is collected by single - chip computer , and then transferred to a personal computer where a software programmed with vc shows the data and a clear image can be seen 在解决纸币图像读入的过程中:从ccd的工作原理出发,系统的分析了ccd和微处理器的接口和时序配合问题,在走纸机构、光学系统的配合下采用单片机系统成功的读入了纸币图像数据。
