This invention discloses a paper processing device, comprising a bottom block, a connecting cavity fixedly arranged in the bottom block, a penetrating cavity communicated with and arranged in the lower end wall of the connecting cavity. The penetrating cavity is communicated with the exterior space. A lifting motor is fixedly arranged in the lower end wall of the connecting cavity, the upper end wall of output shaft of which is fixedly provided with a driving pulley. A driven pulley in the connecting cavity is arranged on one side of the driving pulley. The lifting motor works to drive the driving pulley to rotate to drive the driven pulley to rotate, so an inner threaded block is driven to rotate to drive a threaded rod to move upwards; then a stirring fan is driven to enter a reaction cavity. The automatic structure adopted by this device realizes automation of paper processing.

Disclosed is a battery having a positive terminal and a negative terminal and two electrical connection tongues, each tongue secured to one of the terminals thereof. The battery also includes at least one additional connection tongue secured to one of the terminals thereof, forming a radiating element with the electrical connection tongue secured to the same terminal of the battery.

A push switch capable of indicating a push state comprises a cap, movable stand, base, connecting member, light-emitting module, resilient component, circuit unit, and casing. The cap comprises a surface layer onto which a first UV ink layer, translucent chromium-plated layer, and second UV ink layer are sprayed sequentially. The connecting member is light-penetrable and fitted to the bottom of the cap. The movable stand comprises a body, connecting end portion connected to the connecting member, and limiting portion extending laterally from the body. The movable stand moves whenever the cap is pushed. The base has therein a receiving space. The light-emitting module, resilient component, and circuit unit are disposed in the receiving space. After at least one light-emitting component of the light-emitting module has emitted light, brightness and color of the light emitted is visible through the cap to indicate the push state of the push switch.

A microstructure comprises a plurality of interconnected units wherein the units are formed of graphene tubes. The graphene tubes may be formed by photo-initiating the polymerization of a monomer in a pattern of interconnected units to form a polymer microlattice, removing unpolymerized monomer, coating the polymer microlattice with a metal, removing the polymer microlattice to leave a metal microlattice, depositing graphitic carbon on the metal microlattice, converting the graphitic carbon to graphene, and removing the metal microlattice.
