Abstract: Affords a compound semiconductor substrate packaging method for preventing oxidation of the surface of compound semiconductor substrates.

Abstract: A method and a structure (1) are provided for enclosing a packaging machine (100), which can be divided in at least two work areas or portions (110; 130, 120) having different operation tasks, arranged one after another along a packaging line (2) of the machine (100). The structure (1) includes a plurality of enclosing panels (P), suitably assembled together to form enclosing chambers (3, 4) for protection of each of the work portions (110; 130, 120). At least one of the enclosing chambers (3) is aimed at enclosing, a pressurized environment and at least the other chamber (4) is aimed at enclosing an environment, whose pressure is substantially constant and equal to the outside pressure.

Abstract: A vacuum control valve includes a valve body defining a cavity, an inlet opening and a vent opening. A vacuum supply control member is movably mounted at the inlet opening, and is movable between an open position to open the inlet opening, and a closed position to close the inlet opening. A vent control member is movably mounted at the vent opening, and is movable between an open position to open the vent opening, and a closed position to close the vent opening. The vacuum supply control member and the vent control member are movable independently of each other, for selectively controlling the supply of vacuum when the vacuum supply control member is in the open position and the vent control member is in the closed position, and for selectively venting vacuum when the vacuum supply control member is in the closed position and the vent control member is in the open position.

Abstract: A portable vacuum apparatus comprises a vacuum chamber to be filled with lidded jars, bottles or other containers containing foodstuff or other products for the purpose of storing the contents under vacuum. The vacuum chamber is composed of a platform covered by a layer of a resilient material serving as a seal, and of a removable cover seated on the platform. The chamber is pipe-connected to an electrically operated vacuum pump and to an automatic valve connecting the chamber with the atmosphere in open state. To evacuate the chamber and the jars the valve is manually closed and the pump is started exhausting air from the chamber and the jars. The valve is adapted to open automatically as soon as the required vacuum has been reached and to interrupt the electric supply to the pump motor. The valve is designed to open a wide passageway to the chamber causing the air to rush in and to create a shock wave.

Abstract: Apparatus for evacuating and sealing containers of perishable food or other substances includes a rigid lid for fitting onto the container and a resilientt valve which is situated over a small passage in the lid. The valve has a hollow interior region which is open at the underside of the member and a stem extends down through the passage in the lid and carries an enlargement at its lower end that is broader than the passage. A hollow cup, coupled to a vacumm pump, is temporarily placed over the valve to draw air from the container after which atmospheric pressure urges the lid against the container and urges the valve against the lid to seal the container. The hollow interior of the valve is broader than the passage in the lid and thus atmospheric pressure is effective against an area of the valve that exceeds the area of the passage thereby assuring a very strong and reliable sealing effect.

Abstract: A vacuum storage device comprises a closed vessel for storing food with an air exhaust port provided with a check valve, and a pressure reducing device for drawing out air in the closed vessel with a suction port, either of the closed vessel or the pressure reducing device being provided with structure for hermetically connecting the suction port of the pressure reducing device to the air exhaust port of the closed vessel, the pressure reducing device and closed vessel being removably and hermetically connected to one another by mounting the former on the latter or vice versa.

Abstract: A vacuum storage device comprises a base member, a housing sealingly and removably mounted on the base member to form a storage chamber, a pressue reducing device mounted on either of the base member and housing, and a means for introducing air into the storage chamber. The pressure reducing device comprises a barrel and a bellows pump housed therein, the bellows pump comprising a bellows body with an inlet valve, which opens the bellows body to said storage chamber during the suction stroke, and an outlet valve, which opens the bellows body to the open air during the dischargeing stroke. The pressure reducing device includes a means for communicating its barrel chamber with the storage chamber.

Abstract: A device for sealing a preserving jaw by generation of a powerful vacuum in the head space of the jar. This is put into effect by a hood which is evacuated by means of an external vacuum pump, and is put over the jar's mouth loosely covered with a thin lid, the hood having an air tight seat on the jar. The lid is lifted by the vacuum inside of the hood and the air left within the jar is, consequently, evacuated. A special valve ensures that atmospheric air may not reenter the hood unless the lid had been pressed against the top edge of the jar's mouth, thus creating an air tight seat of both parts. The external overpressure keeps the jar tightly and durably sealed.

Abstract: A container with an air tight lip incorporating a check valve for only evacuating air from the container by a piston suction pump sealed against the lip and around the check valve; the pump being arranged to receive manual pressure to produce the suction stroke and to simultaneously enhance the seal between the lip and the pump.
