  • Publication number: 20230193506
    Abstract: A method of growing a semi-insulating SiC single crystal ingot, the method comprising the steps of: (1) placing a dopant coated with silicon carbide (SiC) and a carbon-based material into a reaction vessel containing a seed crystal fixed thereto; and (2) growing a SiC single crystal on the seed crystal, thereby yielding a high-quality semi-insulating SiC single crystal ingot with a uniform thickness-based doping concentration. In addition, another embodiment relates to a method of growing a semi-insulating silicon carbide single crystal ingot, the method comprising the steps of: (a) placing in a reaction vessel, a composition comprising a carbon-containing polymer resin, a solvent, a dopant, and silicon carbide (SiC); (b) solidifying the composition; and (c) growing a SiC single crystal ingot on a seed crystal fixed to the reaction vessel, thereby yielding a high-quality semi-insulating SiC single crystal ingot with a uniform thickness-based doping concentration.

  • Patent number: 11674713
    Abstract: An air conditioner of present invention comprises a housing having an outer panel forming the exterior and an opening formed on the outer panel, a heat exchanger configured to exchange heat with air flowing into the housing, and a door unit configured to open or close the opening by moving forward or backward from the opening through which the heat exchanged air is discharged. Wherein the door unit comprises a door blade configured to open or close the opening, a door operating part configured to move the door blade forward or backward, and a controller configured to control the air discharged from the opening to be moved forward from the opening in a straight line or to be discharged radially from the opening by controlling a distance between the door blade and the opening.

  • Publication number: 20080168155
    Abstract: The present invention relates to a system and method for a web hard disk server to download broadcast contents from a broadcast content providing server and to store a minimum number of broadcast contents in order to avoid redundancy among downloaded broadcast contents. More specifically, among several individual broadcast contents downloaded or to be downloaded to a web hard disk of the web hard disk server, only one instance of identical broadcast contents is physically stored in a shared manner, so that the capacity of the web hard disk can be efficiently used while users perceive that they use the web hard disk individually.

  • Publication number: 20080168522
    Abstract: The present invention relates to a system and method for receiving and transmitting publically available broadcast programs to a registered external Internet protocol (IP) address. The received broadcast programs are digitally encoded and stored before transmission. More specifically, a broadcast communication converter system includes a broadcast source for creating predetermined broadcast programs in order to provide the created broadcast programs through a public broadcast network, and a broadcast communication converter for receiving the broadcast programs, digitally encoding the broadcast programs to create broadcast communication contents, storing the created broadcast communication contents into a predetermined recording medium, and transmitting the broadcast communication contents to an external broadcast communication contents target through a wired/wireless communication network.
