A pneumatic pusher having a main body, a flow-guiding body, a moving body, and a delivery tube. The flow-guiding body includes a front tube with a smaller diameter and a rear tube with a larger diameter. The delivery tube is mounted on the front tube in such a way that the outer wall of the delivery tube and the inner wall of the main body define a return pressure chamber. A first gas-distributing channel extending from a first air outlet at one side of the main body leads directly to the inner side of the delivery tube. The side of the first air inlet of the main body communicates with a second gas-distributing channel. The second gas-distributing channel includes an exit located at one side of the return pressure chamber of the delivery tube. The air pressure provided through the second gas-distributing channel serves as cushioning force in pushing the delivery tube outwardly. When the moving plunger blocks the gas distributing chamber in such a way that the gas is stopped to be injected through the first gas distributing channel into the pushing chamber for bringing the delivery tube forward, the gas pressure injected through the second gas distributing channel into the return pressure chamber acts as inward return force for the delivery tube. Therefore, the reciprocating movement of the delivery tube on the front tube can be completely done by the airflow.

A vegetable room for a refrigerator includes: a vegetable box (20) disposed inside a refrigerator in which a cooling air supply unit is provided to circulate cooling air therein and a plurality of shelves (10) are provided, and having a receptacle space (5) for receiving food items therein opened upwardly; a box cover (30) for covering an opening side of the vegetable box (20) to close the receptacle space (5) of the vegetable box (20) and having a plurality of cooling air ventilating holes (31, 41) formed at one side thereof to introduce cooling air into the vegetable box (20); a cover support unit (22) interposed between the box cover (30) and the shelf (10) to support the box cover at the shelf; a plurality of opening and closing members (33, 43) for opening and closing the cooling air ventilating holes (31, 41) of the box cover (30); and an operating unit (24) for operating the opening and closing members (33, 43) simultaneously.

A fire sprinkler of the preferred embodiments includes a frame, a trigger, and a deflector. The frame defines a duct to exhaust the flow of a fire suppressing or extinguishing substance, and includes a fastener to fasten the frame to a supply line. The trigger blocks the flow of the fire suppressing or extinguishing substance through the duct during a first mode, and permits the flow of the fire suppressing or extinguishing substance during a second mode. The deflector redirects the flow of the fire suppressing or extinguishing substance into a coverage area. The deflector also at least partially shields the trigger from the dispersal of a fire suppressing or extinguishing substance from an adjacent fire sprinkler and prevents a failure of the trigger.

The present invention provides a liquid discharge head and a method for manufacturing such a head, in which a discharging speed of a liquid droplet can be increased, a discharging amount of the liquid droplet can be stabilized and discharging efficiency of the liquid droplet can be enhanced. The liquid discharge head comprises a heater, an element substrate on which the heater is provided, a nozzle including a discharge port portion having a discharge port for discharging the liquid droplet and a bubbling chamber and a supply path for supplying the liquid to the bubbling chamber and a supply chamber for supplying the liquid to the nozzle and an orifice substrate and, the bubbling chamber includes a first bubbling chamber and a second bubbling chamber above the first bubbling chamber and the discharge port portion is communicated with the second bulling chamber via a stepped portion and a side wall of the second bubbling chamber is converged toward the discharge port with inclination of 10 to 45 degrees and the nozzle is provided with a control portion comprised of a stepped portion in the flow path in the vicinity of the bubbling chamber and a maximum height of the flow path is smaller than a height up to a lower surface of the discharge port portion.

A vegetable room for a refrigerator is provided. The vegetable room includes a vegetable box disposed inside a refrigerator in which a cooling air supply unit is provided to circulate cooling air therein and a plurality of shelves is provided, and having a receptacle space that receives food items therein opened upwardly, a box cover that covers an opening side of the vegetable box to close the receptacle space of the vegetable box and having a plurality of cooling air ventilating holes formed at one side thereof to introduce cooling air into the vegetable box, a cover support unit interposed between the box cover and the shelf to support the box cover at the shelf, a plurality of opening and closing members that open and close the cooling air ventilating holes of the box cover, and an operating unit that operates the opening and closing members simultaneously.
