Abstract:
The present invention relates to a method and device for preparing powder by depositing nano metal, alloy, ceramic particles that are excellent in size uniformity, on a surface of the powder that is a base, using a vacuum deposition method. In particular, the present invention provides a method and device for preparing the powder on which the nano metal, alloy, and ceramic particles of a very uniform size are deposited, by simultaneously performing deposition and agitation using an effective agitation means for solving a disadvantage of a conventional method where deposition and agitation are separately performed. Also, the present invention provides a method and device for preparing the powder on which nano particles are deposited, in which a nano characteristic is kept by preventing a coalescence phenomenon of nano particles even when a deposition time for increasing contents of the nano particles increases in their preparation.
Abstract:
A shopping-mall system utilizing user-based avatars comprises a terminal for transmitting user's three-dimensional image data through a wired or wireless communication network and then selecting any one of items provided through the wired or wireless communication network to receive an avatar image wearing the selected item and to transmit purchase specification information for purchasing the selected item. An avatar creation server receives the three-dimensional image data from the terminal and then creates an avatar image. A three-dimensional shopping-mall server puts any one item selected among a plurality of items stored therein on the avatar image created by the avatar creation server to provide the terminal with the avatar image wearing the item, and then performs an electronic commerce transaction with the terminal on the receipt of the purchase specification information of the selected item.
