The invention provides a flexible display panel and a manufacturing method thereof. The flexible display panel comprises a substrate, an inorganic layer, an organic filling layer, source and drain electrode metal layer wires and a flat layer; the source and drain electrode metal layer wires comprise a first source and drain electrode metal layer wire located in a bending area and a second source and drain electrode metal layer wire located in a non-bending area, wherein the first source and drain electrode metal layer wire is a bent wire; and therefore, the source and drain metal layer wires are alternately subjected to pressure stress and tensile stress when the flexible display panel is bent, the neutralization offset of the pressure stress and the tensile stress can be realized, and thestress is reduced, so that the resistance change of the source and drain metal layer wires caused by the bending can be reduced, and optical change caused by the resistance change is reduced, and meanwhile, the risk of the breakage of the source and drain metal layer wires can be reduced, and the product performance of the flexible display panel is improved.

Provided is a chip-type semiconductor ceramic electronic component having a ceramic body composed of a semiconductor ceramic, first external electrodes formed on the both end surfaces of the ceramic body, and second external electrodes extending to cover the surfaces of the first external electrodes and a part of a side surface of the ceramic body. The electronic component has a small resistance value variance and a small thermal shock resistance change, and in the electronic component, excellent substrate mounting is performed. When a curvature radius of a corner section of the ceramic body is expressed by R([mu]m), the maximum thickness of a layer brought into contact with the ceramic body, among the first external electrode layers, from an end surface of the ceramic body is expressed by y ([mu]m), and the minimum thickness of a layer brought into contact with the side surfaces of the ceramic body, among the second external electrodes, from the apex of the corner section of the ceramic body is expressed by x ([mu]m), an inequality of 20<=R<=50 is satisfied, and when 0.5<=x<=1.1, an inequality of -0.4x+0.6<=y<=0.4 is satisfied, and when 1.1<=x<=9.0, an inequality of -0.0076x+0.16836<=y<=0.4 is satisfied.

A bistable resistance random access memory comprises a plurality of memory cells where each memory cell having multiple memory layer stack. Each memory layer stack includes a conductive layer overlying a programmable resistance random access memory layer. A first memory layer stack overlies a second memory layer stack, and the second memory stack overlies a third memory layer stack. The first memory layer stack has a first conductive layer overlies a first programmable resistance random access memory layer. The second memory layer stack has a second conductive layer overlies a second programmable resistance random access memory layer. The second programmable resistance random access memory layer has a memory area that is larger than a memory area of the first programmable resistance random access memory layer.

The invention relates to a special-shaped wire strand cable conductor and a production method of the special-shaped wire strand cable conductor and relates to a wire and cable special-shaped wire strand round conductor with the nominal cross section ranging from 25 mm<2> to 630 mm<2>. The cable conductor comprises a single round wire and special-shaped wires with all the strand layers designed in the tile-shaped structure according to the specifications of cables. The production method includes the steps that first, according to the designed special-shaped wire structure, the single round wire in the center is manufactured in a drawing mode through a drawbench, and then the special-shaped wires of various specifications of strand layer structures are manufactured on a water tank type or sliding type or fractional motor type drawbench in a drawing mode through a special-shaped high-speed wire drawing die; the round line in the center is placed on a payoff rack of a wire stranding machine, and all the stranding layer special-shaped wires are placed on a frame winch or fork winch and manufactured into the special-shaped wire strand cable conductor through stranding. The outer surface of the cable conductor is smooth and free of burrs, the gap between single wires is small, the filling coefficient is larger than 0.98, and the strand cable conductor is stable in structure. The production method is high in technology universality, and updating and upgrading of the products can be achieved in small and medium-sized enterprises through the technology.
