Focusing the TEA CO2 laser pulse onto a metal target in the vacuum cell, the backward jet of plasma produced by laser pulse can create electric pulse between target and cellwall. The effects of beam focusing and vacuum condition on the conversion are investigated experimentally. The maximum output voltage is 300 V when the peak power density of laser pulse is 1.4x109 W/cm2. Over-all efficiency is 0.01%. Using two separated collecting electrodes, the velocity of plasma expansion can be obtained.

A handprinted character reader (OCR) is described. It is equipped with some adaptive circuits including a scanner capable of performing two dimensional affin-transform, an automatic beam focusing circuit etc. For effective extracting the local as well as the global features of characters a kind of structural method of recognition is developed. In addition, an algorithm for automatic generation of the character dictionary by learning process is implemented.The characters being read include numerals, alphabets and symbols (total 62). The accuracy of recognition is comparable with other handprinted OCR, but the constraints imposed on writing and on document format are fewer. This OCR is designed as an input device for reading handwritten data and programs.

Theory of combined electrostatic and magnetic focusing system has been investigated by I.I.Tsukkerman,but his theory is suitable only for systems with narrow electon beam focusing.This paper surveys the theory of combined electrostatic and magnetic system with wide electron beam focusing for image transference and gives a comment on the Tsukkerman's theory,The article shows that if the principal trajectory equation and its neighboring trajectory equations are expressed in vector form,it will be more convenient and simpler to find out the solutions of trajectories then those trajectory equations expressed in scalar form suggested by I.I.Tsukkerman,Finally,using the theory obtained,a practical example is given for a combined electrostatic and magnetic system with wide electron beam focusing for image transference.
