Abstract: Differential group delay (DGD) devices and techniques based on folded optical paths. An in-line polarization monitor can be provided as a feedback for worst-case alignment without using an in-line polarizer. Polarization maintaining retro reflectors can minimize the introduced higher-order polarization effects caused by reflections between folding mirrors or prisms in conventional schemes.

Abstract: A wholly air-controlled impact mechanism invented for creating a more compact and powerful pneumatic wrench comprises a flying hammer, a pressure impulse generator and a pressure container containing the hammer and the generator. The main part of the flying hammer is a flywheel with 2 cavities and a number of air passages. A pilot valve and an impact pin are fitted in the cavities. The impact pin rests in its cavity during energy-accumulation phase and stretches out rapidly from the flywheel to finish an impact during impact phase. The generator transmits pressure impulse periodically, affecting the differential pressure acting on the pilot valve. The higher the differential pressure, the greater the impact torque developed. The unique design of the air passages of present invention results in a very reliable, powerful and durable energy-accumulating pneumatic wrench. Its production cost is much lower due to simplicity of its configuration.

Abstract: This invention relates to the field of materials of the photorefractive crystal. The composition of these crystals is Li1−xNb1+yO3: Fem, Mn, where M can be magnesium, indium, or zinc; when using q to denote the ion valence of M (q=2 when M is Mg or Zn, and q=3 when M is In), the values of x, y, m, and n are in the range of 0.05≦x≦0.13, 0.00≦y≦0.01, 5.0×10−5≦m≦7.5×10−4, and 0.02≦qn≦0.13. This invention greatly improves the photorefractive properties of LiNbO3 crystals: makes it have a high diffraction efficiency (more than 68%), a fast response speed for photorefraction (an order of magnitude faster than iron doped LiNbO3), and a high resistance to optical scattering (the light intensity threshold to photorefractive fan scattering near two orders of magnitude larger than LiNbO3: Fe). This invention is an excellent three-dimensional optical storage material and has a vast potential market.
