  • Patent number: 10802391
    Abstract: A method of stripping films which are stuck together without damage is disclosed. The whole reel of films which are stuck together is placed in a sealing device with outlet valves. Liquid nitrogen is added at a bottom of the sealing device. The films are stripped off by a flow of gas through gaps between the layers of the films while the vaporization of liquid nitrogen. The present invention adopts a natural force of liquid nitrogen vaporization to strip the films, which does not compromise the PH value, the dimensional performance and the mechanical performance of the films. The films are stripped off without damage. The conventional method of stripping the films causes the fragile film to break off or the image layer with a decreased combing power to detach.

  • Patent number: 10444630
    Abstract: A separating device and method for a bonded cine film, belonging to the field of image file protection and repair technologies. The separating device comprises a pressurizing device, a separating device and a liquid nitrogen storage device. The pressurizing device is connected to the liquid nitrogen storage device; the liquid nitrogen storage device is connected to the separating device for providing liquid nitrogen thereto; the separating device comprises a film receiving chamber for accommodating a film to be separated; the pressurizing device pressurizes the liquid nitrogen storage device allowing liquid nitrogen to enter the film receiving chamber. Due to a difference between expansion coefficients of a base layer and emulsion layer of the film under low temperature, micro-pores and gaps may be generated in the base layer and the emulsion layer of a bonded film roll; the liquid nitrogen penetrates into the micro-pores and gaps of the bonded film.

  • Patent number: 9178623
    Abstract: The present invention utilizes a high-speed serial data transceiver to generate two high-speed electric pulse signals. After passing through a gain network, the signals are used for driving an electro-optic phase modulator (PM) so as to realize phase modulation of photon signals. The present invention may directly use a high-speed digital signal to realize a four-phase modulation function needed by the BB84 quantum key distribution protocol without using a digital to analog converter or an analog switch. This can prevent modulation rate from being restricted by links including digital-to-analog conversion, switching of the analog and the like. A dual-electrode electro-optic phase modulator scheme can also effectively reduce requirements for amplitude of a modulation driving signal, thus facilitating realization of high-speed phase modulation, which meets requirements of quantum key distribution.

The present invention may directly use a high-speed digital signal to realize a four-phase modulation function needed by the BB84 quantum key distribution protocol without using a digital to analog converter or an analog switch. This can prevent modulation rate from being restricted by links including digital-to-analogue conversion, switching of the analogue and the like.
