  • Publication number: 20220234934
    Abstract: A refill system includes a tempering furnace, a refill furnace which stores the molten potassium nitrate obtained by melting powdered potassium nitrate, a supply unit which supplies the molten potassium nitrate to the tempering furnace, a tempering furnace side load measuring unit which measures a load amount of the molten potassium nitrate in the tempering furnace, a refill furnace side load measuring unit which measures a load amount of the molten potassium nitrate in the refill furnace, and a central control unit which checks the load amount of the molten potassium nitrate in the tempering furnace and the refill furnace in real time, and controls the supply unit to stop supplying the molten potassium nitrate to the tempering furnace when the load amount of the molten potassium nitrate in the tempering furnace is greater than or equal to a predetermined load amount.

  • Patent number: 8771545
    Abstract: The present invention relates to an absorbent and a passivation layer for an optical element comprising the same, and more specifically to an absorbent that can be applied to a flexible substrate while blocking the inflow of water, and also not blocking light, and a passivation layer for the optical element comprising the same. Also the present invention relates to an absorbent that can maintain a light-emitting property for a long period of time by minimizing damage to the optical element by using the compound synthesized using a non-polar solvent, and the passivation layer for the optical element comprising the same.
