高速包装机械供纸系统的动态拼接与控制

自动供纸和动态自动接纸是当代轻工包装机械设计的关键技术和重要特征之一。它不仅要求包装机械供纸系统能够随机器的工作速度变化而自动改变供纸速度,而且要求在“在用盘纸”即将用完时,能够自动拼接“待用盘纸”,从而保证在不停机条件下自动换用盘纸。本文以高速卷烟机为对象,分析ＰＡＳＳＩＭ卷烟机供纸系统的工作原理,重点介绍盘纸动态拼接的设计技术,并讨论相应的电气控制过程

Flexible Hybrid Paper Made of Monolayer Co3O4 Microsphere Arrays on rGO/CNTs and Their Application in Electrochemical Capacitors

A facile one‐step hydrothermal method is developed for large‐scale production of well‐designed flexible and free‐standing Co₃O₄/reduced graphene oxide (rGO)/carbon nanotubes (CNTs) hybrid paper as an electrode for electrochemical capacitors. Densely packed unique Co₃O₄ monolayer microsphere arrays uniformly cover the surface of the rGO/CNTs film. The alkaline hydrothermal treatment leads to not only the deposition of Co₃O₄ microspheres array, but also the reduction of the GO sheets at the same time. The unique hybrid paper is evaluated as an electrode for electrochemical capacitors without any ancillary materials. It is found that the obtained hybrid flexible paper, composed of Co₃O₄ microsphere array anchored to the underling conductive rGO/CNTs substrate with robust adhesion, is able to deliver high specific capacitance with excellent electrochemical stability even at high current densities, suggesting its promising application as an efficient electrode material for electrochemical capacitors.

Recyclable,Flexible, Low‐Power Oxide Electronics

The ability to process and dimensionally scale field‐effect transistors with and on paper and to integrate them as a core component for low‐power‐consumption analog and digital circuits is demonstrated. Low‐temperature‐processed p‐ and n‐channel integrated oxide thin‐film transistors in the complementary metal oxide semiconductor (CMOS) inverter architecture are seamlessly layered on mechanically flexible, low‐cost, recyclable paper substrates. The possibility of building these circuits using low‐temperature processes opens the door to new applications ranging from smart labels and sensors on clothing and packaging to electronic displays printed on paper pages for use in newspapers, magazines, books, signs, and advertising billboards. Because the CMOS circuits reported constitute fundamental building blocks for analog and digital electronics, this development creates the potential to have flexible form factor computers seamlessly layered onto paper. The holistic approach of merging low‐power circuitry with a recyclable substrate is an important step towards greener electronics.     

Quantum theory analysis of the action micromechanism exerted on bioparticles from laser microbeams
