A scroll machine has an intermediate pressure cavity which is operable to open and close a leakage path between the discharge zone and the suction zone of the scroll machine. The leakage path is closed when intermediate pressurized fluid is supplied to the cavity and the leakage path is open when the cavity is open to the suction zone of the compressor. A valve which can be mechanical or electrical is used to open and close a passageway extending between the cavity and the suction zone of the machine.

A refrigerator having a basket lift apparatus comprises: a body having cooling chambers for storing food; a basket accommodated in the cooling chamber in a slidable manner; and a basket lift apparatus installed at the basket and lifting the basket when the basket is drawn out of the cooling chamber. When the basket is drawn out of the lower cooling chamber, the basket is lifted by using the basket lifting apparatus thereby to enhance the user's convenience.

According to the invention, there is provided a damper for a flapdoor that does not show any damping effect when its movable shaft of the damper is rotated with the door in one sense whereas it effectively damps the rotary movement of the flapdoor when the movable shaft is rotated with the door in the other sense, wherein a one-way clutch for engaging or disengaging the movable shaft with a movable member depending on the sense of rotation of the movable shaft to cause a viscous shearing drag in the viscous fluid contained in the damper and a power source constitute so many integral parts of a coil spring. A damper for a flapdoor having such an arrangement can have a simplified configuration as compared with a damper provided with a separate coil spring as power source and a separate one-way clutch and therefore can be realized with reduced dimensions. Moreover, since such a one-way clutch can be prepared from a coil spring without requiring any additional processes and by simply engaging a portion of the coil spring with the movable member, the rest of the coil spring functioning as power source, the damper can be realized at a significantly reduced cost.

The present invention relates to dispensers for disposable cutlery. The invention also relates to banded packets of disposable cutlery that can be used in the cutlery dispenser of the present invention, as well as other cutlery dispensers that do not use a cartridge therein. The present invention also relates to disposable cutlery that has been adapted to make it better suited to stacking, such as for use in cutlery dispensers that do not include a cartridge.

Dispenser for disposable cutlery and components therefor

A rotary damper with a directional property is disclosed which is capable of being simplified in structure, manufactured with a low cost, and stably and precisely operated. The rotary damper is constructed in such a manner that a clutch spring is interposed between a revolving shaft and a rotor to selectively carry out the integral rotation of the rotor with the shaft or the stop of the rotor independent from the shaft.
