Abstract:
A service implementing method and apparatus according to an ultraviolet (UV) index in a mobile terminal provides diverse information and services according to the UV index detected by the mobile terminal having a UV sensor mounted thereon. The service implementing method and apparatus includes switching over to a UV alarm function mode when an alarm function is selected in a UV management mode, setting a predetermined time interval for informing a user of the UV index when an alarm interval is selected in the UV alarm function mode. The service implementing method and apparatus further includes setting a specified time for informing the user of the UV index when an alarm time is selected in the UV alarm function mode, and setting avatars or alarm sounds for informing the user of the UV index according to the set time when an alarm method is selected in the UV alarm function mode.

Provided is a shadow mask including a substrate; a mask that is formed to have an opening for transferring a thin film onto the substrate in a desired shape; and a delamination-preventing polymer layer formed on the mask.
Abstract:
A lead free solder is provided. The lead free solder includes about 1.5 wt % to about 2.5 wt % silver (Ag), about 3 wt % to about 6 wt % bismuth (Bi), about 0.005 wt % to about 0.1 wt % of a deoxidizing agent, and a balance of tin (Sn). The lead free solder has improved wettability, a lowered melting point, little or substantially no formation of oxidation layer in a solder bath, suppressed brittleness, improved thermal shock resistance and drop resistance.
Abstract:
A method and apparatus identifying a type of a recordable disc using the reflectivity and RPM (Rotation Per Minute) of the disc. The method includes the operations of detecting an RPM (Rotation Per Minute) of the disc, identifying a first disc type by comparing the RPM with a first reference value, measuring the reflectivity of the disc, and identifying a second disc type between a one-time recordable disc type and a re-recordable disc type by comparing the reflectivity of the disc with a second reference value. Accordingly, the lead-in time of the disc can be reduced.
Abstract:
A door assembly for an oven includes a door configured to open and close a heating chamber of an oven, and a glass substrate removably mounted to a surface of the door facing the heating chamber. An oven includes a housing having a heating chamber formed therein for irradiation of microwaves into the heating chamber. A door is configured to open and close the heating chamber, the door having a filter that prevents microwaves from leaking from the heating chamber. A glass substrate is removably mounted to a surface of the door facing the heating chamber.
Abstract:
A vacuum cleaner includes a body having a suction motor for generating a suction force, a filter for filtering dust sucked in by the suction motor, and an outlet for exhausting air which has been filtered by the filter. A suction head is provided at one side of the body for sucking dust and a suction/exhaustion switch is installed between the body and the suction head. The suction head includes a channel switching valve assembly installed at a lateral surface of the body, a head side suction hose connected between the channel switching valve assembly and the suction head and a body side suction hose connecting the body and the channel switching valve assembly. A suction/exhaustion hose is connected to the channel switching valve assembly for exhausting a part of the exhaustion air exhausted through the outlet to the outside of the body or for sucking dust through the channel switching valve assembly.
Abstract:
A method of and apparatus for setting optimum recording power using characteristic values calculated inversely from recording power that allows a recordable optical disc to have a minimum value of jitter. The method includes setting a first optimum recording power value using characteristic values of an RF signal detected from an optical disc, and recording a predetermined pattern on the optical disc while changing the first recording power value; measuring a value of jitter according to the recorded pattern, and setting a recording power value when a minimum value of jitter is obtained as a second optimum recording power value; inversely calculating the characteristic values from the second optimum recording power value; and setting a third optimum recording power value using the inversely calculated characteristic values. Accordingly, it is possible to improve recording and reproducing qualities of optical discs that have the same time information and ID but their writing/reading speeds and media are different.
Abstract:
The present invention relates to a coating method for the preparation of a coated nuclear fuel. Particularly, the present invention relates to the coating method of nuclear fuel surface with more than two coated layers of carbides, borides or nitrides and their compounds comprising deposition or permeation steps of i) elements or mixture that can form carbides, borides or nitrides and ii) a layer of pyrolytic carbon or boron prepared by chemical vapor deposition(CVD) or sputtering in sequence or in reverse sequence, or nitrogen prepared by gas permeation in sequence, on the nuclear fuel surface. The coated layers are formed with carbides, borides, nitrides or their mixture at high temperature and pressure by a combustion synthesis. The coating method of this invention can be applied to various types of nuclear fuels either in particle or in pellet type and control and preserve fine crystal structure without phase transition since the surface of nuclear fuel coated with pyrolytic carbon and silicon is heated only for several seconds by heat source such as laser beam, arc or microwave. Thus, the present invention is excellent method of coating nuclear fuel surface not only for particle type fuel which used in High Temperature Gas-cooled Reactor (HTGR) but also for pellet type fuel used for Water-cooled Reactors.
