Method and device for realizing liquid crystal arbitrary orientation control through numerical control micromirror array photoetching

A method for realizing liquid crystal arbitrary orientation control through numerical control micromirror array photoetching utilizes a set of projection photoetching system based on a digital micromirror device (DMD), so the collimated ultraviolet or blue light beams are uniformly irradiated to the surface of the numerical control micromirror array DMD, a computer outputs a shape signal to control all the DMD pixels, i.e. single micromirrors are in different reflection states for realizing intermediate photomask, so the all the DMD pixel reflected lights carry out the shape signal control; the beams are demagnified by a microobjective, and then are projected onto a substrate which has the surface coated with a light-operated orientation material through a polarizing film, exposure is completed through controlling the light intensity and time, and the liquid crystal of an exposure pattern area is reorientated; and another substrate is utilized to form a liquid crystal cell, the liquid crystal cell is filled with the liquid crystal, so preset orientation is realized. The method realizes the control and production of arbitrary patterns and orientation directions, and has a potential important application in the fields of wide viewing angle liquid crystal display, adjustable optical communication devices, wavefront correction, light beam control and the like.

Direct drinking nipple

The invention belongs to the technical field of mother and baby products, and particularly relates to a direct drinking nipple. The direct drinking nipple comprises a nipple part, a protective part and a connecting part, wherein the protective part is umbrella-shaped, the top surface of the protective part is connected with the nipple part, and the bottom of the protective part is connected with the connecting part; the nipple part communicates with the connecting part to form a cavity; and the cavity is used for providing a liquid circulation channel when the connecting part is externally connected with a container. The direct drinking nipple can be matched with the container to contain liquid to directly feed a baby, and the container does not need to be replaced during feeding, so thatthe possibility that the liquid is polluted can be reduced, and the direct drinking nipple is convenient to clean. Meanwhile, when the baby does not need to be fed and needs to be pacified, the directdrinking nipple can be used as a pacifier; the umbrella-shaped protective part is arranged on the direct drinking nipple; when the baby eats the nipple part, the connecting part can provide holding positions for the two hands of the baby; and the protective part is umbrella-shaped and can just protect the outer side of the mouth of the baby and wrap the two hands of the baby to prevent the baby hand from eating the hands.

Oil-water separation method and device

The invention discloses an oil-water separation method and an oil-water separation device. A corrugated sheet is driven by a motor to move up and down and rotate, and is driven by a moving shaft to do reciprocation; relative motion of liquid drops occurs through rotation motion of the corrugated sheet; the liquid drops in emulsion fluid with different heights are continuously conglomerated in an up-and-down motion process of the corrugated sheet; after the coagulation is carried out for a certain time, the separation between oil and water is completed; the corrugated sheet has certain length and width, and a zigzag channel for enabling the fluid to flow back and forth on the channel is provided, so that scattered liquid drops are conglomerated to a maximum extent; the corrugated sheet is made of hydrophilic materials, and is oleophylic and free of sticking oil; oil drops are adsorbed and are continuously conglomerated on the sheet, and after the oil drops are increased to a certain extent, the corrugated sheet moves to an oil layer and is blended into the oil after the oil drops are broken; through up-and-down motion and rotation motion, the oil drops are conglomerated during floating and float during coagulation; impurities glide by means of gravity, and a gap between stacked sheets is difficultly blocked.
