摘要:
An apparatus includes a housing, a crucible disposed in the housing, and a collection bin. A turnplate disposed in a powder collection area is of an inlaid structure. A concentric circular groove is provided on the atomization plane. An air hole is provided in the turnplate. The present invention combines the pulsated orifice ejection method and the centrifugal atomization method, in cooperation with the turnplate structure and subjecting the turnplate surface to induction heating, so that a metal liquid is allowed to break through the split mode of traditional molten metal, achieves a fibrous split mode that can be implemented only when an atomizing medium is an aqueous or organic solution, and prepares a high-melting-point metal powder that meets requirements, and has a controllable particle size, high sphericity, no satellite droplets, and good flowability and spreadability, and is suitable for industrial production.

An apparatus for efficiently preparing spherical metal powder for 3D printing includes a housing, a crucible and a powder collection area arranged in the housing, wherein a turnplate arranged in the collection area is an inlaid structure. A material having a poor thermal conductivity is selected as the base of the turnplate, and a metal material having a wetting angle less than 90° with respect to droplets is selected and embedded into the base to serve as an atomization plane of the turnplate. An air hole is disposed in the turnplate. The spherical metal powder for 3D printing combines electromagnetic force breaking capillary jet flow and centrifugal atomization, which breaks through the traditional metal split mode, and makes the molten metal in a fibrous splitting.

An apparatus efficiently preparing ultrafine spherical metal powder includes a housing, a crucible and a powder collection area arranged in the housing. The turnplate arranged in the powder collection area is an inlaid structure. The part inlaid into the body part acts as an atomization plane of the turnplate. The atomization plane is provided with a concentric circular groove, and the turnplate is provided with an air hole. The apparatus is used for preparing ultrafine spherical metal powder by on-by-one droplets centrifugal atomization method, mainly combining the uniform droplet jet method and the centrifugal atomization method, which breaks through the traditional metal splitting model, makes the molten metal in a fibrous splitting, so as to efficiently prepare ultrafine spherical metal powder with narrow particle size distribution interval, high sphericity, good flowability, excellent spreadability, uniform and controllable size, no satellite droplets and suitable for industrial production.

An Extensible Markup Language (XML) document management method includes: receiving an XML document management operation request sent via an XCAP protocol, by an XML Document Management Server (XDMS); determining that the XML document management operation request is in an entrustment mode, and determining whether to perform an operation described in the XML document management operation request in accordance with access permission information corresponding to an XML document, by the XDMS.
摘要:
A system for a package pre-fetching for a remote program installation. The system includes a cache and a service program unit. The service program unit receives a request for a package required for an installation of an operating system and at least one peripheral application thereof from a computing node. The service program unit determines a package request sequence by which the computer node issues one or more package requests according to a type of the computing node, so as to pre-read a subsequent package from an external storage device into the cache before the computing node issues a request for the subsequent package.

The present invention discloses a method for realizing presence service. By recording a correlation between a watcher identity and a class in an authentication configuration information of a presentity for a watcher and making presence information related to a corresponding class in the presence information issued by the presentity, a presence server determines that presence information may be obtained by the watcher according to a correlation between classes and watcher identities and presence information. The invention further discloses a system for realizing presence service, a presence information processing device and a presentity client.
