Abstract:
The present invention relates to a method of conducting a gift sale using a magnetic card, and more specifically to a method of conducting a real-time gift sale using a magnetic card in which the gift sale participant passes a magnetic card through the slot of a card reader that can read magnetic cards such as credit cards and department store cards to operate a gift sale program to display the winning result on screen and the winning result is printed out as a gift exchange receipt and the gift winner presents it to a gift exchange place to have the gift provided.
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:
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:
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 a vacuum insulation panel and to a method for manufacturing same. The method comprises: (a) a step of laminating a plurality of glass fiber boards to form a core, wherein the glass fiber boards are produced by a papermaking method using glass fiber dispersed in an inorganic binder; (b) a step of forming an outer cover having a structure in which a surface protection layer, a metal barrier layer, and an adhesive layer are laminated; (c) a step of producing a getter by packing burned lime (CaO) powder in a pouch; (d) a step of attaching the getter onto the core, or inserting the getter into the surface of the core; and (e) a step of forming the outer cover into a bag body, inserting the core from step (d) into the bag body, and sealing the bag body, thereby improving long-term durability of the vacuum insulation panel.
