The invention relates to an ammonia water absorption refrigerating machine driven by marine exhaust, belonging to the technical field of refrigeration. The ammonia water absorption refrigerating machine comprises a generator, a backheating process component, a cooling process component, a subcooler and an evaporator, wherein the backheating process component is respectively connected with the generator and the cooling process component; the cooling process component is connected with the subcooler; and the subcooler is connected with the evaporator. The invention simplifies a rectifying device and enables the structure of an integral system to be compact, thereby being beneficial to miniaturized production; an absorber enables ammonia and ammonia water to flow in parallel-connected slim tubes by utilizing the channel flow characteristics of vapor and liquid inside a pipeline, therefore the absorption property of the system is not influenced by marine bumpiness and wobble; the generator enables the ammonia water to boil in a plurality of parallel-connected slim tubes by utilizing the boiling inside the slim tubes, and no welding point exists in the generator, therefore the reliability of the generator can be effectively enhanced.

The present invention provides an anti-miscontrol switch. The anti-miscontrol switch comprises an anti-miscontrol device and a switch. The anti-miscontrol device comprises a component pipe, a passivecomponent and a limit bar; the component pipe is provided with an anti-misoperation track and a control track; and the passive component is fixedly connected with the limit bar. The switch comprisesa switch control part and a switch body; the component pipe is fixedly connected with the switch body; the switch control part is arranged below the passive component; and the passive component is provided with a wedge-shaped chute. In the natural state, the limit bar can always move up and down along the anti-misoperation track. The present invention also provides a socket. The socket comprises acontrol structure, and the control structure can be inserted into the chute to contact with the inclined surface portion of the chute, so that after the control structure is inserted into the anti-miscontrol device, under the pressing action of the control structure, the passive component always has the tendency of deflection; and when the limit bar moves down to the connection between the anti-misoperation track and the control track, the passive component rotates, and the limit bar is driven to enter the control track, can continue to move down to continue to squeeze the button switch, andfinally control the on and off of the switch.

The invention discloses a waveguide-based display module and display device. Based on the principle of wavelength division multiplexing, the image generation unit modulates a mixed light beam containing at least two groups of sub-images with different wavelengths; the image generation unit modulates The mixed light beam is coupled into the waveguide module. The waveguide module has a multi-layer in-coupling unit and a multi-layer out-coupling unit. Each layer of in-coupling unit is designed to couple in different wavelength ranges of light. The image to be displayed is spliced ​​from the outgoing image after the mixed light beam of the display image is coupled out by the waveguide module coupling unit. The invention solves the problem of both large field of view and miniaturization of the near-eye display module with a brand-new idea.

The invention relates to a lateral electro-optic Q-switching switch based on a trigonal crystal system and its method and application for reducing driving voltage, including polarizers and electro-optic crystal devices arranged in sequence along the optical path. The electro-optic crystal device is an electro-optic crystal, and the electro-optic crystal belongs to Trigonal crystal system; the angle between the polarization direction of light before passing through the electro-optic crystal and the X / Y direction of the electro-optic crystal is 45°. The driving voltage of the electro-optic Q-switching switch of the present invention is relatively low, which is 15%-60% lower than the quarter-wave driving voltage of the traditional electro-optic Q-switching switch, and satisfies the important requirement of electro-optic devices driven by low voltage. The design of the electro-optic Q-switching switch of the present invention is more concise, without using a quarter-wave plate, the cavity structure is more simplified, and the volume is smaller, which is conducive to miniaturized production, simplifies the design and volume of the laser, and has the advantages of easy industrialization. .
