Abstract:
Disclosed is a heat-dissipating substrate, which includes a base substrate including a metal layer, an insulating layer formed on one surface of the metal layer, and a circuit layer formed on the insulating layer, a heat sink layer formed on the other surface of the metal layer, a connector for connecting the base substrate and the heat sink layer to each other, an opening formed in a direction of thickness of the base substrate and into which the connector is inserted, and an anodized layer formed on either or both of the other surface and a lateral surface of the metal layer, and in which the metal layer and the heat sink layer are insulated from each other by means of the anodized layer, thus preventing transfer of static electricity or voltage shock to the metal layer. A method of manufacturing the heat-dissipating substrate is also provided.
Abstract:
A mobile apparatus includes a processing planner and a plan processor. The processing planner generates a plurality of resource use plans in response to a context monitoring query (CMQ) of an application, and selects a final plan satisfying a request of the CMQ among the resource use plans. The plan processor executes the final plan. Accordingly, the mobile apparatus may support resource-efficient context monitoring.
Abstract:
A cathode for lithium secondary batteries coated with a slurry including an active material, a binder and a solvent, and further including a polymerization inhibitor, is disclosed. Gelation of the slurry is prevented during production of the cathode so that adhesion of the slurry is enhanced, thus achieving improved coating properties of the cathode and facilitating the coating of the slurry.

Abstract:
The present invention relates to an arrow for hunting that includes: an arrow shaft member of a predetermined length having a recess part formed on one end thereof so as to insert a bowstring of a bow thereinto and a spiral insertion protruding part formed at the inside on the other end thereof; a plurality of wing members mounted near the recess part of the arrow shaft member in such a manner as to be spaced apart by a predetermined distance from each other along the outer periphery of the arrow shaft member; and an arrowhead having a pointed shape at the end thereof in such a manner as to be adapted to be inserted into the body of the hunting target and a spiral protruding part formed along the outer periphery of the end portion protruded from the other end thereof.
Abstract:
A high luminance and high output LED package using an LED as a light source and a fabrication method thereof. The LED package includes an Al substrate with a recessed multi-stepped reflecting surface formed therein and a light source composed of LEDs mounted on the reflecting surface and electrically connected to patterned electrodes. The LED package also includes anodized insulation layers formed between the patterned electrodes and the substrate, and an encapsulant covering over the light source of the substrate. The LED package further includes an Al heat radiator formed under the LEDs to enhance heat radiation capacity. According to the present invention, the substrate is made of Al material and anodized to form insulation layers thereon, allowing superior heat radiation effect of the LED, thereby significantly increasing the lifetime and light emission efficiency of the LED package.
