在批林整风运动中,上海沪江机械厂广大革命职工认真学习马列,坚持唯物论的反映论,狠批唯心论的先验论,经过一个多月的努力,试制成功晶体管控制木工平刨安全装置。该装置的工作原理:当刨木板手离刨刀相近时(距离可以调节),由于人体具有电容作用,使装在刨刀一侧的金属板立即受晶体管振荡装置感应而发生信号,从而使主电机断电停转,并使电磁铁刹车装置通电,刹住刀轴,动作的
In the campaign of rectification and reorganization of forests, the revolutionary workers and staff of Shanghai Hujiang Machinery Factory conscientiously studied Marxism-Leninism and Marxism, adhered to the theory of materialism and rejected the priori theory of idealism. After more than a month of hard work, the successful trial of successful transistor control of woodworking planing safety devices was carried out. The working principle of the device: When the planing hand near the planer (distance can be adjusted), due to the human body has a capacitive effect, so that the platen mounted on one side of the metal plate immediately by the transistor oscillation device sensing signal, so that the main motor off Electric stop, and electromagnet brake device power, brake knife shaft, action
