A three-dimensional structure, and a method and device for producing the structure, where the structure has pressure resistant characteristics despite its voluminous and elastic nature and has higher resistance to surface wear and mechanical dimensional stability than a foamed polyethylene sheet. The three-dimensional structure is characterized in that a resin sheet has needle-like projections on its both faces, each projection has a height (H) of 3 mm or more, the height (H) and a width (W) of the projection at the height of H / 2 has a relationship of H≧2.5 W, the projection has a hole in its tip, and the projections are joined to a sheet-like object at their tops. The method of producing the three-dimensional structure is characterized in that a large number of needle-like dies are integrated with a base plate, and a pair of the base plates are arranged so as to be opposed to each other, and a resin sheet is deformed when the pair of the base plates move parallel to each other so as to intrude into the resin sheet. Further, a method of continuously producing the three-dimensional structure is provided.

A stimuli responsive compound includes: a unit A having bonds that function as rotation axes; a first unit B disposed at a first bonding section of the unit A; a second unit B disposed at a second bonding section of the unit A; a first unit C disposed at a third bonding section of the unit A; and a second unit C disposed at a fourth bonding section of the unit A. The first unit B bonds with the second unit B by oxidation-reduction reaction, and the first unit C and the second unit C have liquid crystallinity and include polymerizable functional groups.

The invention provides an electromagnetic pulse boosting type gradual deep drawing forming method. The electromagnetic pulse boosting type gradual deep drawing forming method comprises the steps that a sheet to be formed is placed between a female die and a male die; performing is conducted and the sheet to be formed is pressed into the female die, wherein the sheet to be formed is located at the bottom of the male die; electromagnetic force is applied to the portion, located at the bottom of the male die, of the sheet to be formed, and the sheet to be formed is pushed downwards; electromagnetic force is applied to the periphery of the sheet to be formed, the sheet to be formed is pushed to the center of the female die, and the sheet to be formed is made to flow into the female die; down force is applied to the male die so that the male die can move downwards, and therefore downward deep drawing is conducted on the portion, located on the lower portion of the male die, of the sheet to be formed; stamping deep drawing and electromagnetic pulse deep drawing are conducted repeatedly before deep drawing forming of the sheet to be formed is completed. According to the electromagnetic pulse boosting type gradual deep drawing forming method, the traditional male die forming technology and the electromagnetic pulse forming technology are combined, stamping deep drawing and electromagnetic pulse deep drawing are conducted alternately, and the depth of deep drawing forming of a cylindrical part is increased. The invention further provides an electromagnetic pulse boosting type gradual deep drawing forming device.

Disclosed is a blue phase liquid crystal display panel which includes an upper substrate and a lower substrate which are disposed opposite to each other, and blue phase liquid crystals provided between the upper substrate and the lower substrate. The upper substrate is provided with a first common electrode on a side facing the blue phase liquid crystals, and the lower substrate is provided with a second common electrode and a plurality of pixel electrodes on a side facing the blue phase liquid crystals. The pixel electrodes each extend towards the first common electrode, thus forming a horizontal electric field between the upper substrate and the lower substrate. According to the present disclosure, higher horizontal field intensity can be achieved so that the external drive voltage of the blue phase liquid crystals can be greatly decreased.

The invention relates to a microstress-induced reaction method and a preparation method of pointer nuclear-shell microparticles using the same, and provides a microstress-induced reaction method, which comprises the following steps: inducing the stress applied to a structure in a microspace so as to change the morphology of the structure, wherein the structure in the microspace is coated by a completely sealed medium so as to separate from an outside space; the concentration of a liquid at the outer side of the medium is higher than that of the liquid at the inner side. The invention further provides a preparation method of pointer nuclear-shell microparticles.
