Abstract:
Disclosed are a vacuum insulation panel and an insulation structure of a refrigerator using the same. The vacuum insulation panel comprises a core material formed by gather glass fiber, a getter having a container to receive an absorbent having quicklime of 90wt% or greater as a main component, and a sealing cover formed to surround the core material and the getter. The core material can be formed at low cost in such a manner that glass fiber is tangled and gathered by penetrating glass wool having glass fiber using a needle. Since the getter is made of quicklime that can first remove water corresponding to a main component of the absorbent, the getter can be manufactured at low cost and has improved insulation efficiency.
Abstract:
The present invention relates to a method of conducting a gift sale using a RF card, and more specifically to a method of conducting a real-time gift sale using a RF card in which a non-contact type RF card stored with his own specific number is issued to the gift sale participant and the card is contacted with a RF card reader to operate a gift sale program to display the winning result on screen and when he returns the card to a gift exchange place the won gift is confirmed and given.
Abstract:
A vacuum insulation panel and an insulation structure of a refrigerator applying the same are disclosed. The vacuum insulation panel comprises: a sealing cover (120) having an outermost layer exposed to the outside, a gas shielding layer stacked on the bottom surface of the outermost layer and formed of a thin metal sheet and a metal deposition film, and a heating-fusion bonding layer stacked on the bottom surface of the gas shielding layer and formed of an octane-base material; a core material (110) sealed by the sealing cover (120) in contact with the heating-fusion bonding layer, and provided with an extended insulation portion (130) some parts of which are extended between the bonding portions formed at the sealing cover (120); and a gas permeation preventing layer (125) formed on the sealing cover (120), so that can prevent an external air or moisture from penetrating into a vacuum insulation panel.
Abstract:
The present invention relates to an automatic fireproof shutter. The automatic fireproof shutter includes: a plurality of panels selectively descending so as to cover a gate, the plurality of panels being rotated with respect to an end of the shutter such that the plurality of panels are stacked in the thickness direction thereof; an elasticity-generating device providing elastic force to the plurality of panels in order to elevate the panels; a detection device detecting either a human voice, an impact, or an electric signal when the plurality of panels descend; a driving device elevating the plurality of panels to a preset height and then lowering same according to the signal provided by the detection device; a force transmission device transmitting the power provided by the driving device to the plurality of panels, thereby transferring the plurality of panels; a stacking device stacking the plurality of panels transferred by the power transmission device in the thickness direction; and a case receiving the plurality of panels, the elasticity-generating device, the driving device, and the stacking device therein.
Abstract:
The present invention relates to an environmentally-friendly detergent composition containing natural food additives, which has no bubbles and excellent cleaning ability, deodorizing properties, and sterilizing properties for effectively adsorbing and removing microorganism, agricultural chemicals, heavy metal, and the like from the surface of fruits, vegetables, etc. The environmentally-friendly detergent composition of the present invention is safe to the human body in terms of sanitation, and leaves no materials that are harmful to food. The detergent composition of the present invention has significantly high biodegradability and solubility, and therefore, is free from water pollution and the destruction of the ecological system.
Abstract:
The present invention relates to an appliance having a micro-pattern (190b) for displaying a pattern or a character, and a method for fabricating a structure having a micro-pattern (190b), and more particularly, to a method for displaying a pattern or a character more effectively. To achieve above object, the appliance of the present invention includes a body, a structure provided to an outside or an inside of the body, and a micro-pattern (190b) for changing a light incident thereon from an outside of the micro-pattern to a light of a predetermined color to display a predetermined character or a predetermined pattern on the structure.
Abstract:
Disclosed are injection moldings, an injection-molding apparatus and a method thereof. The injection-molding apparatus comprises: a cavity mold having a cavity; a core mold having a core surface to form a molding space for injection moldings when being joined to the cavity mold; a heating unit for heating the cavity mold or the core mold; a cooling unit for cooling the cavity mold or the core mold; and a patterning stamp having a micrometer or nanometer sized pattern and provided on an inner surface of the molding space. According to the injection-molding apparatus, a micrometer or nanometer sized pattern is formed on a surface of injection moldings so as to have a super-hydrophobic characteristic and an optical characteristic, and a micrometer or nanometer sized pattern of a complex structure can be implemented.
