The Effect of Base Support Rigidity on Laser Phototypesetter Vibratory Performance 基础支承刚度对激光照排机振动性能的影响
Based on the theory of rotary mechanical vibration, the mathematic model of the laser phototypesetter vibration provoking by rotor unbalance was established, and the theoretical analysis matches the experimental results on the whole. 在旋转机械振动理论的基础上,建立转子不平衡引起激光照排机振动的数学模型,理论分析与实验结果基本吻合。实验结果表明:增大基础支承刚度,能够减小转子不平衡引起的振动;
Laser Phototypesetter with four electro-optical modulators 四路电光调制的激光照排机
This paper describes a phototypesetter with four scanning laser beams. There are four He-Ne Lasers and four acousto-optic modulators in the phototypesetter. 本文介绍了四束激光扫描照排机,照排机内安装有四支氦氖激光器及四个声光调制器。
