A stent (1) is a vascular prosthesis for a constricted body vessel. The stent (1) includes a tubular support frame (2) of ring segments (3) arranged in axial succession and formed by struts (5, 6) which in initial state are joined continuously in a wave-like manner. Adjacent ring segments (3) are linked by differently long connectors (9, 10) with U-shaped compensating sections (11, 12). All connectors (9, 10) point in the same circumferential direction (U). Moreover, differently long connectors (9, 10) alternate in circumferential direction (U) as well as in longitudinal stent axis (L).

A slotted turbine static nozzle airfoil. In one embodiment, the turbine static nozzle airfoil includes a concave pressure wall having a slot extending therethrough; a convex suction wall adjoined with the concave pressure wall at respective end joints; and a pocket fluidly connected with the slot and located between the convex suction wall and the concave pressure wall, wherein at least one of the convex suction wall or the concave pressure wall includes a thinned segment proximate one of the respective end joints, the thinned segment configured to extend the pocket toward a trailing edge of the turbine static nozzle airfoil.

The present invention discloses a micro-electro-mechanical system (MEMS) device, comprising: a substrate with at least one opening; and a membrane supported on the substrate, the membrane including at least two thin segments and a thick segment connected together, wherein the two thin segments are not at the same level, and the thick segment is formed by a plurality of layers including at least two metal layers and a via layer, such that the membrane has a curve cross section.

The invention discloses an artificial hip joint replacing device. According to the technical scheme, an artificial hip joint prosthesis which is adjusted flexibly, and can meet movement requirements of all directions, and has high wear resistance of related contact surfaces needs to be provided, an implanting tool needs to be improved, and operative wounds need to be reduced. The artificial hip joint prosthesis comprises a femoral stem, a femoral ball head and an elastic connection part, the far end of the femoral stem can be inserted into a femoral intramedullary cavity, and the near end of the femoral stem extends upward slantly; under a natural state, the included angle between the axis of an extending end and the axis of the femoral stem is 110-140 degrees, the end of the extending end suddenly slims into a step shape, the thin segment extends upward slantly for 6-10 mm and is used for fixing the elastic connection part, and the femoral ball head is connected with the other end of the elastic connection part; a column-shaped protrusion with the length of 6-10 mm is arranged on the connection portion between the femoral ball head and the elastic connection part, and the elastic connection part is fixedly connected with the femoral ball head through the column-shaped protrusion. Therefore, random adjustment of the artificial hip joint prosthesis in each angle is achieved, in particular to the adjustments of the front rake and the collodiaphysial angle on the sagittal view and the coronal view respectively.

Tartary buckwheat daqu liquor is characterized in that the liquor is prepared through the method which comprises the steps that A. materials are prepared, namely clean and dry tartary buckwheat, common buckwheat, highland barley, phaseolus angularis, broomcorn, sticky rice and pteridium squilinum are sufficiently prepared; a. the tartary buckwheat, the common buckwheat, the highland barley, the phaseolus angularis, the broomcorn and the sticky rice are smashed respectively, the average grain size after smashing is 1 / 4-1 / 8 of the size of raw material particles; b. the pteridium squilinum is crushed into thin segments with the lengths not larger than 3mm; c. 20%-50% of the smashed tartary buckwheat, 20%-30% of the smashed common buckwheat, 10%-30% of the smashed highland barley, 5%-8% of the smashed phaseolus angularis, 5%-10% of the smashed broomcorn, 5%-10% of the smashed sticky rice and 2%-5% of the crushed pteridium squilinum thin segments are weighed according to the raw material overall weight and are evenly mixed to form mixed materials; B. the mixed materials are produced with a mixed steaming continuing grain method, the materials are put into a pit in low temperature, a pit pool is sealed for 75-80 days, then multi-section liquor taking is carried out, and tartary buckwheat daqu base liquor is obtained. The tartary buckwheat daqu base liquor is stored in a segmenting mode for standby application, blending is carried out according to needs, and the tartary buckwheat daqu liquor is obtained. The daqu liquor is nutritional type healthy high-class drinking white spirit which has soft flavor and is fragrant, thick, pure and mild.

The invention relates to a forming method of a titanium alloy ultra-thin segment-shaped part. The method comprises the following steps that a titanium alloy sheet is placed between a lower mold and anupper mold of a forming tool, wherein the lower mold is of a hard metal structure with a segment-shaped groove, the segment-shaped groove is used for forming a hemispherical shell structure of the titanium alloy ultra-thin segment-shaped part, the upper mold is a medium-hard polyurethane soft mold with a preset thickness, a stepped through hole is formed in the thickness direction of the upper mold, and the stepped through hole is located right above the segment-shaped groove; punching is carried out on the upper mold, under the action of pressure, the titanium alloy sheet and the upper moldare laminated and are recessed and deformed towards the lower mold, and the hemispherical shell structure matched with the segment-shaped groove of the lower mold is expanded in the segment-shaped groove of the lower mold; and after the titanium alloy ultra-thin segment-shaped part with the hemispherical shell structure is formed, pressure release is carried out on the upper mold, the upper mold is restores to an original shape, the formed titanium alloy ultra-thin segment-shaped part is taken out from the lower mold, and annealing is carried out on the part.

The invention discloses a segment hoisting structure and method in ship construction. The structure comprises two distance maintaining beams, a plurality of clamp plates and hoisting lugs. The distance maintaining beams are arranged at intervals on the deck in a thin segment having low strength. Each clamp plate is a square structure. The side edges of each clamp plate are welded to the lower endportions on both sides of each distance maintaining beam. The bottom edge of each clamp plate is welded to the deck. The clamp plates are connected with the distance maintaining beams and the deck. The clamp plates on the same side of the distance maintaining beams are arranged at intervals. The clamp plates on the opposite sides of the distance maintaining beams are arranged oppositely. Accordingto the weight and the position of the center of gravity of the segment, the hoisting lugs are welded to both sides of the distance maintaining beam at intervals. The segment hoisting structure suspends the segment by hoisting the distance maintaining beams. The hoisting structure and method ensure the structural strength during hoisting, prevent deformation, improve construction efficiency and reduce labor cost.
