摘要:
The present invention relates to a conductive paste composition. The conductive paste composition includes a binder resin including a urethane group present in a main chain or a side chain, especially a binder resin formed from isocyanate and a polymer with at least one hydroxyl group, a fine powder, a glass frit, and a solvent. The conductive paste composition can have a superior physical property, improve productivity and an environmental problem by reducing waste fluid such as aqueous alkaline solution, and form a fine pattern having an improved structure. Accordingly, the paste composition is especially useful for a paste for gravure offset printing.

Disclosed is a Ringer solution infusion controlling apparatus which enables the infused amount and infusion state of a Ringer solution to be easily monitored by an administrator and which automatically blocks infusion of the Ringer solution when the infusion of the Ringer solution is completed. The Ringer solution infusion controlling apparatus includes a body coupled to a chamber receiving a Ringer's solution from a Ringer bottle in which the Ringer's solution is stored and ejecting the Ringer's solution in a state in which the Ringer's solution is maintained at a constant level by first coupling means, a sensing ball provided in the chamber and floating on the Ringer's solution, and elevating according to the level of the Ringer's solution in the chamber, an elevation sensor installed in the body and sensing elevation of the sensing ball, a Ringer's solution transfer blocking unit installed in the body and having a Ringer hose passing therethrough, the Ringer hose allowing the Ringer's solution ejected from the chamber to be transferred, and blocking transfer of the Ringer's solution by compressing the Ringer hose when it is detected by the elevation sensor that the sensing ball deviates from a predetermined range, and a wireless transmitter installed in the body and wirelessly transmitting a Ringer's solution transfer blocking signal to a nurse's room when the transfer of the Ringer's solution is blocked by the Ringer's solution transfer blocking unit.
