Abstract: A non-contact force type micro-rotating mechanism driven by attractive/repulsive force and a manufacturing method thereof, belongs to the field of intelligent micro devices, and mainly relates to micro electromechanical system technology, precision machining technology, precision assembly and the like. The mechanism adopts the interaction force between magnetic poles to replace the connection mode of a traditional through-hole bearing pressure spring positioning shaft, so that the component part structure of the mechanism can be optimized, and the space utilization rate can be greatly improved. Moreover, the attractive force type structure also has the effect of weakening the radial vibration of the motor, and the coaxiality of the rotor and the stator is improved in the running process of the motor. Meanwhile, the rotating mechanism does not directly output shaft work, a structure can be added on the disc-shaped rotor to realize different functions, an actuator and a control object are integrated.

Abstract: The invention discloses a dual-band spectral imaging system based on a digital micromirror device (DMD) and an implementation method thereof. The system mainly comprises a front collimating light path composed of a target 1, a front collimating lens assembly 2 and a DMD 3, and two spectral dispersion light paths with different working wave bands. A target image can be divided into columns by n micromirror scanning units of the DMD 3, and bidirectional scanning of the target image is realized by controlling the n micromirror scanning units to deflect forward and backward in sequence, so that detectors of the two spectral dispersion light paths are each provided with n dispersive spectral images. Then spectral reconstruction is completed according to the principle that each spectral image corresponds to a different target image unit, thereby the dual-band spectral information of a target scene is obtained.

Abstract: A plasma display panel for multi-screen system comprising a front and a back dielectric plates; transparent and addressing electrodes orthogonally located between the plates; display cells defined by the mutually orthogonal electrodes; barrier ribs for separating and defining display cells from each other; and a very narrow sealing seam for sealing edge parts of the two plates. The sealing seam has a width ranging from about 0.3 mm to about 1.5 mm. The sealing material is a glass powder having a special composition that enables a low melting point. A concave groove accommodates the sealing material. The present invention prevents the image from missing between the adjacent units in the display matrix and eliminates the dark matrix border lines.
