To reduce the costs of the assembled components of a pressure adjusting unit, and to efficiently perform the assembling work, and to make the pressure adjusting unit compact under a new idea, and to make a table cooker compact and light weight, a small-sized pressure adjusting unit is provided. The compact pressure adjusting unit is constituted so that the head part, the supporting shaft, and shaft legs can be integrally formed via a valve, and that the supporting shaft can be axially supported so as to be freely rotated in a recessed part formed in the pressure adjusting chamber. Also, the outer diameter of a diaphragm is made compact. Concretely, the outer diameter of the diagram is set so as to be 3.2 cm or less in the case of the pressure adjustment of a table cooker.

The present invention provides a metal composite sealing pad for a high-temperature proton exchange membrane fuel cell, and applications thereof. The metal composite sealing pad comprises a hollow ring-shaped sheet-like sealing metal substrate, wherein more than two through holes are arranged close to the hollow region and on the sealing substrate, first annular sealing bosses are circumferentially arranged around each through hole on one side surface of the substrate, the other side surface of the substrate corresponding to the first annular sealing bosses is provided with annular concave grooves circumferentially around the through holes, any two through holes are separated by the annular sealing bosses circumferentially around the through holes, second annular sealing bosses are arranged on one side surface of the sealing metal substrate and circumferentially around the hollow region and the through holes, the other side surface of the substrate corresponding to the second annular sealing bosses is provided with annular concave grooves circumferentially around the through holes, the first annular sealing bosses and the second annular sealing bosses are positioned on one side surface of the sealing substrate, and both side surfaces of the sealing substrate are respectively provided with an insulating anticorrosion coating.

The invention discloses a video cloud platform resource dispatching method and device. The video cloud platform resource dispatching method includes that detecting a resource demand mode of a video application; acquiring a plurality of resource pools of which the surplus resource is larger than the static resource in physical resource needed for running the video application, detecting the resource consumption mode of each resource pool, wherein each resource pool comprises the resource set of the physical resource needed for the video application running; confirming the resource pool for providing the physical resource needed for the video application running in the acquired resource pools according to the resource demand mode of the video application and the resource consumption mode of each resource pool. The video cloud platform resource dispatching method can dynamically, quickly and effectively dispatch the physical resource needed for the video application running based on the reliable resource demand mode and resource consumption mode; in the resource dispatching process, a user does not need to embed codes in the video application, and the resource can be well used for a cloud computing environment.

The invention discloses a lithium battery with novel current collectors and a preparation method of the lithium battery with the novel current collectors. The lithium battery comprises a positive pole piece, a diaphragm and a negative pole piece. The positive pole piece comprises a novel positive pole current collector in a multi-layer structure, the positive pole current collector comprises a first plastic film, and each of upper and lower surfaces of the first plastic film is coated with a first adhesion reinforcement layer, an aluminum metal plating layer and a first antioxidant layer sequentially. The negative pole piece comprises a novel negative pole current collector in a multi-layer structure, the negative pole current collector comprises a second plastic film, and each of upper and lower surfaces of the second plastic film is coated with a second adhesion reinforcement layer, a copper metal plating layer and a second antioxidant layer sequentially. The preparation method includes: laminating the positive pole piece, the diaphragm and the negative pole piece, packaging through aluminum-plastic films, injecting an appropriate amount of electrolyte, and subjecting the aluminum-plastic films to hot-press packaging. The lithium battery has advantages that light weight, energy density improvement and cost reduction of the battery can be realized, and copper / aluminum plating layers are less prone to shedding and oxidization.
