储能式印字机构的磁系统与动态特性

储能式点阵针式打印机因有很多优点而受到越来越多的关注,但对其印字机构的理论分析计算方面的文献还较少。本文注意到该机构磁系统具有永久磁铁的特点,提出一种较简易的方法,解决其磁路计算问题,并阐述击打件动态特性的分析。最后,对一实际机构进行了计算,获得该机构一系列参数的数值。其结果可用来评价这种印字机构磁系统与印字条件的技术性能。上述方法适用于同类型印字机构的分析计算。

An automatic measurement device for the evaluation of the print quality of printed characters

When using OCR equipment (OCR = Optical Character Recognition) it is necessary to define shape and print quality of the characters in national and international standards.The paper gives a review of the standardization of the character fonts OCR A and OCR B for optical character recognition. All relevant parameters are discussed which define the print quality of printed characters. A critical review of two measurement methods used so far for the evaluation of print quality parameters is given. The improvement of the measurement methods led to the development of an automatic measurement device which is described in detail.The automatic measurement device consists of a high precision scanning device to digitize the printed characters and a computer program for the evaluation of the data. The mechanical construction and the properties of the scanning device are explained. The computer program consists of two main parts for preprocessing of the scanned data and for the evaluation of the different print parameters.Test results are reported and possible applications of the measurement device are discussed.

高光泽彩喷纸图像打印质量的优势因素分析

采用灰关联分析方法对影响高光泽彩色喷墨打印纸图像打印质量的因素进行了优势因素分析.结果表明,纸张的粗糙度对高光泽彩喷纸打印图像的色密度、色域、色差和清晰度等均有非常明显的影响.而光泽度对纸张打印性能的影响并不显著.     

嵌入式控制系统LCD驱动问题研究

文章讨论液晶（LCD）显示驱动问题。液晶显示模块一般由控制器、驱动器和显示屏组成,不同型号的显示模块只要使用同一型号的控制器,驱动程序基本相同。液晶显示控制器根据结构可分为TN、STN和TFT几种,根据功能则有字符型和点阵型之分。字符型LCD只能显示西文字符和笔划较少的汉字,功能较少,价格低廉,编程容易;点阵型LCD功能强大,可以显示较复杂的汉字和各种曲线。虽然LCD产品型号繁多,功能各异,但其驱动程序还是有规律可循。本文就液晶显示驱动规律谈自己的工作体会,供同行参考。

Polymerization of fluoroacrylate and guar gum copolymer as a new pretreatment paste for ink‐jet printing of polyester

A novel pretreatment paste containing fluoroacrylate copolymer and modified Guar Gum was carried out on the polyester fabric to provide partial water repellency and printability after inkjet printed with water‐based disperse dye inks. The stable fluorinated pastes were prepared via miniemulsion polymerization of fluoroalkyl acrylates, styrene, 2‐ethylhexyl acrylate, and modified guar gum in the presence of AIBN as initiator, CTAB and polyoxyethylene polyaryl ether as surfactants under suitable reaction conditions. In the analysis of monomer conversion and particle size, the highest polymerization rate with smallest particle size was obtained with increasing concentration of surfactants and initiator but the decreasing degree of substitution of guar gum to imply stronger interactions between fluoroacrylate monomers, hydroxyl groups of modified guar gum and EO units of nonionic surfactants. The 30% of stock fluorinated paste with urea concentration of 6% provided the prints with highest K/S value, satisfactory edge acuity and least color difference between front and back sides of the fabric to show more transparency. The rating 80 of water repellency tested on the best treated polyester fabric demonstrated stain proof properties after sprayed with water and dried. © 2009 Wiley Periodicals, Inc.
