Abstract:
The present invention discloses a manufacturing method and apparatus of artificial human teeth using dental CT. The method comprises the steps of: removing a damaged part of human teeth; obtaining surface coordinates of the teeth using a dental CT machine located at a dental clinic for a medical checkup; converting the surface coordinates of the actual teeth to CAD/CAM data; manufacturing artificial teeth by cutting metal or ceramic with a three-dimensional N/C machine using the converted data; obtaining shape data of upper or lower actual teeth corresponding to the artificial teeth; changing the shape of the artificial teeth by direct surface processing according to the shape data of the upper or lower teeth; and coating ceramic to the artificial teeth after sintering the processed artificial teeth for a predetermined period.
Abstract:
Disclosed is an embedded printed circuit board, in which electronic devices having different thicknesses can be embedded together, thus achieving highly dense electronic devices, and when electronic devices having considerably different thicknesses are embedded, two electronic devices which are comparatively thinner can be embedded in a perpendicular direction, thus reducing an embedding area and suppressing warping of the printed circuit board, and an insulating member the thickness of which is variably adjusted is interposed between base substrates, so that spaces between the electronic devices are completely filled therewith, thus solving the problem of void defects, resulting in reliable printed circuit boards, and, when a base substrate includes a core made of metal, the printed circuit board can less warp. Also a method of manufacturing the embedded printed circuit board is provided.
Abstract:
An image forming device and a print file storage method thereof, in which a file name of a print file transmitted from a host apparatus can be automatically modified to a file name designated by a user at a time of storing the file. The image forming device includes a storage part including a folder to store print files transmitted from external apparatuses, a user interface to set a storage environment of the folder so that the file name of the print file can be modified, a controller to control the file name to be modified and stored in the folder according to the set storage environment, when the print file is stored in the folder. When the file name of the print file transmitted from the external apparatuses is stored in a predetermined order according to the file name or a folder name designated by the user, it is possible to automatically modify and store the file name of the print file without input by the user.
Abstract:
Disclosed herein are a fuel nozzle of a gas turbine combustor for dimethyl ether (DME, CH3OCH3) and a design method thereof. The fuel nozzle includes a pilot fuel injection hole formed at the center of the nozzle and a plurality of fuel injection ports formed at equiangular positions around the pilot fuel injection hole to inject DME. Each of the fuel injection ports includes a pair of upper and lower DME injection orifices communicating with a fuel-air mixture injection swirler. The upper DME injection orifice becomes gradually wider, whereas the lower DME injection orifice becomes gradually narrower. Thus, DME can be optimally combusted in the gas turbine combustor, thereby achieving cost reduction of power plants, enhancement in reliability of the power plants, and diversification of usable fuel.
