An impingement heat transfer device for transferring heat between a stream of temperature controlled air and a product wherein an air supply duct and an air return duct have a common wall. A tube has one end communicating with the inside of the air supply duct and another end extending through an opening in the air return duct. Air is circulated to reduce pressure in the air return duct and increase pressure in the air supply duct such that a stream of air flows through and out of the tube and spent air is drawn through the opening encircling the tube into the air return duct.

By designing the ultrasonic vibration microtube extrusion mould capable of realizing vertical feeding, ultrasonic vibration is combined with the plastic microtube extrusion moulding, thus reducing flow resistance, increasing the production efficiency and obtaining the plastic microtube with high quality.

The invention relates to a Docker container based network load balancing system and an establishment method and an operating method thereof. According to the invention, a Docker container technology is adopted to act as a foundational technology of the system, and the complete network load balancing system is realized on a server host by using the characteristic that a Docker container saves hardware resources and can establish a lot of containers in the server host; and a Web server is added through container mirroring conveniently and quickly so as to perform shunting on the access amount or a data stream by using the characteristics that the Docker container can be established in a second level through mirroring and that the containers established through mirroring can be ensured to be identical. The Docker container based network load balancing system not only can save the implementation cost of the system, but also can efficiently solves a problem that the original system cannot bear because of increase in access amount or data stream.

The invention discloses a route cluster planning method, which is applied to vehicle navigation. The method comprises the following steps: carrying out route generation on a navigation source address and a destination address of users at minimum cost; dividing groups according to the navigation source address and the destination address of the users to generate road net groups; and generating a traffic flow demand resource expectation according to the divided road net group and distributing the optimum road resource in combination with the road condition. The mutual interference between the vehicle passing behaviors in different groups is minimum, the load balance is realized, routes are reasonably planned, the traffic resources are fully utilized, the flow of load in an urban road net is effectively balanced, traffic jam of urban roads is alleviated and relieved, and the technical effect of traffic capacity of the urban road net is greatly improved.

One or more of three different measures are taken to preheat a wafer before it is loaded into direct contact with a wafer holder, in order to provide optimal throughput while reducing the risk of thermal shock to the wafer. The first measure is to move the wafer holder to a raised position prior to inserting the wafer into the reaction chamber and holding the wafer above the wafer holder. The second measure is to provide an increased flow rate of a heat-conductive gas (such as H_s purge gas) through the chamber prior to inserting the wafer therein. The third measure is to provide a power bias to radiative heat elements (e.g., heat lamps) above the reaction chamber.

The invention relates to a Docker Swarm container cluster-based network load balancing system, a building method and a working method thereof. The network load balancing system comprises a reverse proxy server, a host, and multiple background Web servers, wherein the host comprises multiple server hosts, the reverse proxy server receives a connection request from Internet and forwards the connection request to the background Web server on an internal network, and the background Web server outputs a result and returns the output result to a client requesting connection on the Internet. In the system, multiple servers with Docker clients are connected to form a cluster by using a Docker Swarm container cluster; the whole cluster comprises a multi-state server, and has enough hardware resource and calculating capacity, thereby being capable of processing larger network load; and defects of insufficient hardware resource and limited calculating capability of a single server are overcome.

The invention aims at providing a coaxial dual-electromagnetic fuel gas injection valve with the flowing sectional area adjustable. The adjustable gas injection flow is achieved through a dual-valve-element dual-electromagnet control structure. The air inflowing and flow guiding process is achieved through a bypass structure and a flow guiding cavity structure; valve element control and gas way control are achieved through actuator control, and a gas injection function is achieved; through cooperation of an external guiding structure, an internal flow guiding cavity and a pressure balancing groove, the perpendicularity of a valve element is guaranteed, stable and reliable work of gas flow is achieved, and the high responding speed is achieved; through a mixed gas inflowing mode of combining direct gas inflowing of an axial main gas groove and gas inflowing of circumferential gas supplementing holes, high flow is achieved, the gas supplying efficiency of an engine is effectively improved, and meanwhile gas flow interference can be avoided, so that gas way stability is achieved; face sealing and high reliability of the fuel gas injection valve are achieved through multiple annular strip structures between the valve element and a valve base.

Tooling for the injection station of an injection blow molding machine includes a set of individual mounting bracket assemblies that attach an elongated manifold block to the lower die set of the machine. The relatively slender brackets are designed to have minimal thermal contact with the manifold block without sacrificing stability and structural integrity. Standard sizes of the brackets maybe manufactured in advance to accommodate manifold blocks of different lengths but standard widths.
