The invention belongs to the technical field of ferroelectric memories and particularly relates to a non-volatile ferroelectric memory with high read current and an operation method thereof. Each storage unit of the non-volatile ferroelectric memory is of an in-plane capacitor structure or up-down capacitor structure; polarization directions of ferroelectric materials are respectively vertical to electrodes; when enough large write voltage opposite to an electric domain polarization direction of a ferroelectric is applied to the two electrodes, ferroelectric domains in the corresponding regions of the electrodes are inversed from the polarization direction along an electric field direction, the electric domain polarization direction between the electrodes is opposite to the peripheral ferroelectric domain polarization direction, a domain wall is formed between the two electric domains, and the domain wall is usually an electric channel; when information is read, the read current of the electric channel is directly proportional to the perimeter of the electric domain wall, the longer the perimeter of the electric domain wall is, the larger the read current is. According to the ferroelectric memory of the invention, the read current in the storage unit can be improved to be helpful for improving the read speed of data and the reliability.

The invention relates to a preparation method of a large-sized and high-heat-conductivity natural graphite radiating film. The preparation method includes the steps: taking natural flake graphite as araw material and preparing highly oxidized graphite extremely easy to clean by an improved oxidized graphite preparation method; dispersing the oxidized graphite in a solvent to prepare slurry; coating a substrate with the slurry; drying an obtained wet film, and demolding and winding the film; performing carbonization or hydroiodic acid reduction treatment; performing graphitization treatment and calendaring to obtain the high-heat-conductivity natural graphite radiating film. By the method, the low-cost natural graphite film which is 3-20 micrometers in thickness, 50-200 millimeters in width and more than 2 meters in length can be prepared quite simply, the in-plane heat conductivity of the prepared graphite film can reach 1460Wm<-1>K<-1>, and the electrical conductivity of the preparedgraphite film can reach 5700Scm<-1>.

The invention discloses a stainless steel water meter shell blank and a machining method thereof, a stainless steel water meter shell and a water meter. The machining method comprises the steps of part dismantling, stamping forming, cutting, part machining, assembly, furnace welding and the like. The machining method is characterized in that the to-be-machined blank is decomposed into parts such as a shell male sheet, a shell female sheet and an inner ring; the shell male sheet and the shell female sheet are configured to be of a mirror image structure in plane symmetry, and are matched to form an inner cavity structure of the water meter shell; a containing space for allowing a water meter movement to be arranged is formed in a cavity; the matching relation between the inner ring and theshell male sheet as well as between the inner ring and the shell female sheet is configured into the mode that the plane where a fixing hole of the inner ring is located and the plane where a shell opening is located are parallel or basically parallel; and then stainless steel is used as a material to conduct hydraulic cold punching forming, and finally the shell blank is obtained through assemblyand welding. The water meter is made of the safer stainless steel material, in the machining process, energy consumption is lower, more environmental friendliness is achieved, reusing after recyclingis achieved, and the comprehensive cost is greatly lowered.

In performing exposure for forming patterns being fine as well as having great density difference, adequate corrections are to be enabled for suppressing the influence from peripheries of these patterns to be a minimum and for suppressing the dimension variation within the plane of semiconductor substrate or among semiconductor substrates to a minimum. So-called lower-layer corrections are executed, in order to suppress the three-dimensional influence, namely the influence of the film-thickness distribution of a lower-layer structure body lying under a subject film to be processed with a resist. A pattern-correcting portion adjusts the amount of exposure such that it cancels the in-plane film-thickness distribution of the lower-layer structure body in respective exposure regions.

The invention relates to a wall type composite damper capable of improving lateral resistance performance of a modularized building structure and a manufacturing method. The wall type composite dampercomprises an upper structure and a lower structure; the upper structure and the lower structure comprise end plates, connecting plates, clamping plates, rib plates, grooves and copper pieces; the ends of the connecting plates are connected with the end plates, the clamping plates are arranged in the middles of the connecting plates, the connecting plates are connected with the clamping plates through high-strength bolts, the rib plates are respectively arranged on the two sides of each connecting plate, the ends of the rib plates make contact with the end plates, and the other ends of the ribplates extend to the clamping plates; the grooves are formed in the inner side surfaces of the ends of the clamping plates, and the copper pieces are arranged in the grooves and make rubbing contactwith the connecting plates; the construction of the lower structure is completely same with that of the upper structure, and the connecting plate of the lower structure is connected with the connecting plate of the upper structure.

The invention relates to an automatic-turning foldable deskboard which comprises an X-axis turning mechanism, a Y-axis turning mechanism, a base block and a retainer plate. The base block and the retainer plate are fixed; the X-axis turning mechanism comprises a deskboard connecting mechanism, a limit block and an elastic torsion device, and the limit block is fixedly connected with a revolving shaft of the deskboard connecting mechanism coaxially; when the deskboard connecting mechanism turns into a horizontal state, the retainer plate locks the limit block in plane so as to support the deskboard connecting mechanism; the elastic torsion device is arranged between the base block and the deskboard connecting mechanism and provides a torsion force for driving the deskboard connecting mechanism to turn into the horizontal state; the Y-axis turning mechanism comprises an elastic tension device, a pull rod and a draw plate, wherein the pivot point between the draw plate and the base blockis higher than the stop point, for stopping the draw plate, of the base block, the pull rod drives the X-axis turning mechanism to warp slightly by taking the stop point as the base point under actionof the elastic tension device, and based on the state, a gap is reserved between the retainer plate and the limit block so that friction resistance between them is reduced.
