Abstract:
An LED package having an anodized insulation layer which increases heat radiation effect to prolong the lifetime LEDs and maintains high luminance and high output, and a method therefor. The LED package includes an Al substrate having a reflecting region and a light source mounted on the substrate and connected to patterned electrodes. The package also includes an anodized insulation layer formed between the patterned electrodes and the substrate and a lens covering over the light source of the substrate. The Al substrate provides superior heat radiation effect of the LED, thereby significantly increasing the lifetime and light emission efficiency of the LED.
Abstract:
An insulation structure for high temperature conditions and a manufacturing method thereof. In the insulation structure, a substrate has a conductive pattern formed on at least one surface thereof for electrical connection of a device. A metal oxide layer pattern is formed on a predetermined portion of the conductive pattern by anodization, the metal oxide layer pattern made of one selected from a group consisting of Al, Ti and Mg.

Disclosed herein is an arrow for hunting. The arrow includes an arrow shaft having a predetermined length and including a nock on one end and a shaft threaded part in the other end. A plurality of feathers is positioned to be adjacent to the nock of the arrow shaft. A connector includes a connecting threaded part fastened to the shaft threaded part, a stopper, and a penetration threaded part. An arrowhead is connected to the connector in such a way as to be opposite to the connecting threaded part. A penetration rotary unit has a threaded part to be fastened to the penetration threaded part of the connector, is shorter than the penetration threaded part, and has wings. A spring is positioned between the stopper and the penetration rotary unit, and provides a restoring force to bias the penetration rotary unit toward the arrowhead.
Abstract:
A light emitting diode package which is superior in heat radiation and easily manufacturable. In the light emitting diode package, an Al substrate has a reflective cup formed thereon. At least one light emitting diode chip is disposed on a bottom surface of the reflective cup. An Al anodized film extends through the Al substrate to divide the bottom surface of the reflective cup into a plurality of substrate electrodes. Here, at least one of the substrate electrodes is surrounded by the Al anodized film. Also, the substrate electrodes are connected to a light emitting diode chip, respectively.

Abstract:
The present invention relates to a polishing composition comprising 30 to 99 wt % of deionized water, 0.1 to 50 wt % of powder of metallic oxide and 0.01 to 20 wt % of cyclic amine. This polishing composition can be used in a chemical mechanical polishing of thin films in integrated circuit manufacturing and has an effect of minimizing the occurrence of microscratches on the thin film after polishing. Thereby it can be applied to the manufacturing process of highly integrated circuits such as Shallow Trench Isolation.
