Abstract: Disclosed herein is a portable roaster used when outdoor cooking or camping is enjoyed. The portable roaster with improved portability and handleability can be changed into a single briefcase form so that it is easy for the user to carry it, can accommodate a windshield, a vertical transfer part, a charcoal plate, and a grill inside the body of the portable roaster so that meat can be grilled and eaten by, e.g., a barbecue grilling method outdoors through easy assembly, it is convenient to store portable roaster in a vehicle or warehouse, and the handling of the portable roaster is very convenient, and allows a cover to be used as a substitute for a table so that the portable roaster is highly versatile.

Abstract: A lighting device includes a plurality of LED light sources, a plurality of lens parts respectively disposed on front surfaces of the plurality of LED light sources to collect and irradiate light emitted from each of the plurality of LED light sources, and a controller for controlling operations of the plurality of LED light sources, wherein the plurality of LED light sources include visible-light LEDs and at least one ultraviolet LED and each of the plurality of lens parts includes a condensing lens disposed on the front surface of each of the plurality of LED light sources to decrease a divergence angle of light emitted from each of the plurality of LED light sources and a fly eye lens part disposed on a front surface of the condensing lens to stack the light on a light receiving surface.

Abstract: A cooling system of a computed tomography (CT) system provides for a more efficient operation than known heretofore. The cooling system of the CT system includes a gantry and a table that moves an object into a bore of the gantry. The gantry includes part boxes mounted therein, and blade elements are formed in regions of the part boxes. The cooling system of the CT system includes a cooling method that includes a multiple cooling method including a stand-by mode and an operating mode.

Abstract: Cooling systems of a CT system and methods of cooling the CT system are disclosed. The CT system includes a gantry and a table that moves an object into a bore of the gantry, wherein the gantry includes a cover having a front surface in which at least an inlet slot is formed and a rear surface in which exhaust holes are formed along with exhaust fans in the rear surface of the cover of the gantry. Fans for the in-take and exhaustion of air are not required to be formed on the front surface of the cover of the gantry. A hole through which external air is taken in through the inlet slot is moved in a rotor of the gantry.

Abstract: Disclosed is an electronic switch. The electronic switch includes a fixed contact point; a movable contact point; and an actuating unit for moving the movable contact point, wherein at least one gas inflow space is formed in at least one of the fixed and movable contact points, a gas which is injected into a space where the fixed and movable contact points make contact with or are separated from each other flows into the at least one gas inflow space while the fixed and movable contact points make contact with each other, and the gas in the at least one gas inflow space is exhausted to the space where the fixed and movable contact points make contact with or are separated from each other while the fixed and movable contact points are separated from each other.

Abstract: An electronic device and method for navigating content to a desired a page based on a duration of touch input includes receiving a touch input at a particular region of displayed contents, counting and displaying a page to the desired page during which the touch input is in contact with the display screen, reaching and displaying the desired page when the touch input is lifted, and further turning to the page including the content according to a further gesture detected thereon.
