Disclosed herein is a hot tool which machines a workpiece made of foam material. The hot tool of the present invention includes a motor, a rotary unit which is coupled to the motor, and an electrode terminal which is connected to an outside power supply and contacts an electrode of the rotary unit. The hot tool further includes a heating body which is coupled to the rotary unit so that the heating body is heated by electric current supplied through the electrode terminal, with a spiral groove formed in a circumferential outer surface of the heating body. The hot tool further includes a polymer storage case which is provided at an upper position on the circumferential outer surface of the heating body, so that molten polymer that moves along the spiral groove is stored in the polymer storage case. Therefore, the hot tool of the present invention has increased machining accuracy and prevents a workshop from becoming messy due to molten polymer.

The variable lamination rapid prototyping apparatus of the present invention includes a first feeding means which longitudinally reciprocates a sheet, a second feeding means which is provided under the first feeding means and reciprocates in a direction transverse to the sheet, and a rotating means which is coupled to the second feeding means and rotates around an axis parallel to the transverse direction of the sheet. The apparatus further includes a translation means which is linked to the rotating means, a cutting means which is coupled to the translation means, and a stacking means which subsequently stacks a plurality of cut sheets, thus forming the 3-dimensional object. The apparatus further includes a control means which previously stores data about the object therein and controls the above-mentioned plurality of means based on the data. Because a hot wire is provided in a parallelogram link structure, superior cutting accuracy and the stability are ensured. Furthermore, because the link structure is adjustable in length, it is possible to easily cut a sheet regardless of the size of the sheet.

Disclosed herein is a three-dimensional (3-D) shaping apparatus and method using a non-contact type heating tool. The 3-D shaping apparatus includes three feeding units, an indexing table and a non-contact type heating tool. The feeding units move in three different directions perpendicular to each other. The indexing table includes a support frame provided with support arms uprightly extending, a seating member hinged to the support arms, and a fixing chuck rotatably combined with the seating member and adapted to grip one side of a soft material. The seating member is placed to be rotated around one of the three moving directions of the three units, and the fixing chuck is placed to be rotated around a rotating axis perpendicular to a rotating axis of the seating member. The non-contact type heating tool is mounted on one of the feeding units to shape soft material by thermally resolving the soft material without contact with the soft material.

The present invention relates a method of coloring a three-dimensional (3D) object while moving the 3D object or a pigment spray nozzle based on the configuration and color data of the 3D object. The method includes the steps of (a) setting the movement path of the 3D object or the pigment spray nozzle based on the configuration data, (b) identifying a narrow color region whose curvature is large and whose range to be colored is narrow, and a wide color region whose curvature is small and whose range to be colored is wide, and (c) coloring the narrow color region and the wide color region identified at step (b) selectively using different pigment spray nozzles whose sizes are different from each other while moving the 3D object or the pigment spray nozzles along the movement path set at step (a).

A heating tool for shaping a soft material is provided. The heating tool is mounted to a predetermined position of a shaping apparatus and connected to a power source provided at a predetermined position of the shaping apparatus to melt and shape the soft material under a high temperature. The heating tool includes shaping parts which come in contact with the soft material to melt the soft material, and heating parts which are provided to be in non-contact with the soft material. The heating parts collect the molten soft material and thermally decompose the molten soft material. The heating tool enables a surface of the soft material to be perfectly thermally decomposed. Thus, the present invention prevents the soft material from being undesirably deformed, due to the molten material remaining after a shaping process.

A web page prefetching apparatus and method for efficiently prefetching a web page using link class information indicating preference of client devices for links contained in a web page. A client device includes a user input unit receiving a user input signal for a web page request; a controller receiving a first web page provided by a first web server based on a user input signal requesting the first web page, requesting a second web page provided by a second web server from the second web server, which is determined based on link class information indicating the preference of client devices for links contained in the first web page, without a user input signal, and receiving the second web page from the second web server; and a storage unit storing the second web page. Accordingly, since the reliability and efficiency of prefetching can be increased, prefetched web pages can be quickly provided to a user.

Provided are a broadcast receiving apparatus, and a method for executing an application in the broadcast receiving apparatus. The broadcast receiving apparatus includes: a controller which assigns a channel number of the broadcast receiving apparatus to an application; a storage unit which stores the channel number; a user input unit which receives a user input signal; and a communication unit which controls data transmission or reception through an interactive communication network, wherein, if the user input signal selects the channel number, the controller executes the application. Accordingly, by utilizing the broadcast receiving apparatus, users can easily access services which are provided through an interactive communication network.
