The present invention discloses a wobble-disk type slide valve flow-distributing axial plunger pump (motor). It mainly includes the following several portions: front cover, shell body, cylinder body, driving shaft, wobble disk, plunger and flow-distributing shaft. Said invention also provides the concrete structure of the above-mentioned every portion and the connection mode of all the above-mentioned portions. Besides, said invention also provides the working principle of said plunger pump and its concrete operation method.

A stay-on-tab container closure suitable for use on beverage cans and the like, said closure including an center panel with an downwardly displaceable tear panel, which, in one aspect, has a smooth upper surface having no visually perceptible contour features, and which, in another aspect, has low-relief contour features on its upper surface. Closures according to the invention have reduced stresses across the score defining the tear panel, thereby reducing the likelihood of stress-induced fatigue cracking which can lead to score failure when the container closure is joined to a can body and the resulting can is internally pressurized.

The present invention relates to a connector-incorporated multi-core optical fiber with a high optical transmission spatial density and with an excellent bending property. An intermediate region of a fiber body of the connector-incorporated multi-core optical fiber is a region located between bundle sections in which a plurality of optical fibers are integrated by a coupling material, and the coupling material is removed in part from this intermediate region, thereby to expose parts of the respective optical fibers located in the intermediate region.

The invention discloses a wide face copper plate of a sheet billet hopper-shaped crystallizer and based on a transition curve and a manufacturing method. According to the wide face copper plate, the transition curve and a circular curve are adopted, combined and connected to form a transverse curve on the basis that a billet shell solidification contraction and deformation mechanism is taken intoaccount, and therefore the situation that the transverse curvature of a cast billet continuously changes is guaranteed, and the transverse stress of a billet shell is reduced; and a hyperbolic taper curve is adopted by a longitudinal curve, and the change of the curvature of the portion nearby the meniscus face is large so that the requirement for the taper of the portion nearby the meniscus facecan be preferably met. The wide face copper plate of the sheet billet hopper-shaped crystallizer and based on the transition curve has the advantages that the design of the transverse curve and the longitudinal curve conforms to the solidification contraction rule of the cast billet, and therefore the stress of the cast billet is conveniently reduced, the generation probability of cracks of the cast billet is reduced, and the requirement of the high casting speed for the copper plate of the sheet billet crystallizer is met.

The invention relates to the technical field of computers, in particular to a computer server cabinet system which comprises a cabinet body and a shock isolation platform used for supporting the cabinet body. The interior of the cabinet body is divided into a containing cavity and an independent cavity, a set of stand columns are symmetrically welded to the inner walls of the two ends of the containing cavity, and lap joint frames are attached to the stand columns; a water tank is placed in the cabinet body and located below the independent cavity, and a water adding hole is formed in the top of the water tank. The shock isolation platform comprises a supporting base, vertical shock isolation assemblies are installed at the four corners of the bottom of the supporting base, and each vertical shock isolation assembly comprises a top base, a stable support, a shock isolation spring, a shock isolation air cylinder, a shock isolation plug rod and a protection cover. Water-cooling heat dissipation is adopted, the interior of the water tank is divided into the cooling box and the transition box through the overflow plate, the interior of the cooling box is cooled through the semiconductor chilling plate, and meanwhile the shock isolation effect of the cabinet body can be improved.

The disclosure provides an independent support of outlet system in a steam reformer furnace. The thermal expansion of the firebox and/or header box that occurs during operation of a reformer is decoupled from the manifold. The manifold is supported independently on a separate saddle support that supports and allows the manifold to move, while the manifold is still substantially enclosed in the header box. The header box is allowed to expand thermally into different configurations without forcing a substantial change in the manifold configuration. Further, the present invention allows the transfer lines coupled to the manifold through connection tees to laterally move the manifold and reduce lateral stress on the manifold. Thus, the invention provides for independent support of the manifold that allows vertical, lateral, and longitudinal thermal expansion of associated components without overstressing the manifold and causing failures.

The invention discloses a key structure. The key structure comprises a bottom plate, a first actuating part and a key cap; the first actuating part is arranged on the bottom plate, is combined with the key cap and is used for enabling the key cap to movably reciprocate perpendicular to the bottom plate in the actuating direction. One of the first actuating part and the key cap is provided with a first slot; and the other one of the first actuating part and the key cap is provided with a first plug. The first plug is arranged in the first slot in a penetrating mode in the direction parallel tothe actuating direction. One of the first slot and the first plug includes at least one first projection that projects outwardly perpendicular to the actuation direction and is conformally engaged with the other of the first slot and the first plug. And on the premise of achieving a good interference clamping effect, the risk of bursting due to overlarge transverse stress when the slot and the plug are combined is effectively reduced.
