Lightweight robust thin flexible latex gloves having areas of reinforcement at areas of high stretch and/or movement are provided. Gloves comprise a knitted liner having a plurality of stitches made from a first yarn having a denier 221 or less, the knitted liner comprising a plurality of finger components, a thumb component, and a palm component; and at least one reinforcement section located at a base of at least one finger component, at a base of the thumb component, in the palm component, or combinations thereof, and a polymeric latex coating. Reinforcement sections can be formed by plaiting, using yarn of a heavier denier, and/or forming Jacquard or transfer stitches. The liner can be knitted using with 70 to 221 denier nylon 66 multi-filament yarn. Methods of making and using the gloves are also provided.

A housing (1) is provided with an eject lever (3) for ejecting a card (10). The eject lever holds a locking member (4) to be swingable around a support shaft (13). The housing is provided with a cam portion (7). The locking member is provided with a cam follower portion (14) to be engaged with the cam portion and a locking portion (15) for locking the card to inhibit the release of the card. When the eject lever is made to perform sliding movement, the cam portion and the cam follower portion cooperate to swing the locking member so that the card is locked and unlocked by the locking portion.

The present invention relates to a spiral wound reverse osmosis membrane element which is formed by winding at least one set of water purification membrane module around a central treated water pipe, and each set of the water purification membrane module is formed by laminating a mesh-like treated water flow guiding member, a reverse osmosis membrane and a mesh-like feed water flow guiding member; the reverse osmosis membrane is folded at a folded side to form a feed water flow channel therein along its inner surface; a treated water flow channel is formed between outer surfaces of adjacent reverse osmosis membranes; the mesh-like feed water flow guiding member is disposed inside the feed water flow channel; the mesh-like treated water flow guiding channel is disposed inside the treated water flow channel; the treated water flow channel is opened only at a treated water outlet which opens towards the central treated water tube, and the treated water flow channel is closed and sealed at remaining three sides; the feed water flow channel is closed and sealed at areas remote from the central treated water tube at two sides adjacent to the folded side, so that the feed water flow channel forms small sections of raw water inlets respectively at areas closer to the central treated water tube at the two sides, and a concentrate outlet is formed at the feed water flow channel at a side opposite to the folded side. The improved reverse osmosis membrane element of the present invention increases the water flow velocity along the membrane surface and therefore reduces concentration polarization and slows down the speed of contamination of the spiral wound type membrane element, and thereby enhancing the durability of the membrane element.

An annular endless belt (1), comprising a release layer (2) formed of fluororesin and having an outer surface formed of a molded surface disposed as an outermost layer, a support layer (6) disposed as an innermost layer, and an elastic layer (4) disposed between the outermost layer and the innermost layer, whereby the fluororesin layer as the release layer can be formed by coating on the outer surface of the endless belt without hardening the elastic layer thereof used as the fixing belt of a color copying machine.

A carrier and a two-component developer are provided. A coating resin layer for coating a core material contains fine particles of titanium oxide which comprise an anatase-type crystal and a rutile-type crystal, and a carrier coating amount of the coating resin layer falls in a range of from 5% by weight to 20% by weight. In addition, a content rate of the rutile-type crystal falls in a range of from 5% to 20% on the basis of the total amount of crystal, and the weight of the fine particles of titanium oxide falls in a range of from 5% by weight to 50% by weight relative to the weight of the core material. Further, the primary particle size of the fine particles of titanium oxide falls in a range of from 40 nm to 80 nm.

An electrolyte membrane 16 is arranged inside first and second frames 13 and 14. The electrolyte membrane 16 has a first surface, on which an anode side electrocatalytic layer 17 is superimposed, and a second surface, on which a cathode side electrocatalytic layer 18 is superimposed. The electrocatalytic layer 17 has a surface on which an anode side gas flow path formation body 21 including a gas flow path 21c for supplying fuel gas is superimposed. Further, the electrocatalytic layer 18 has a surface on which a cathode side gas flow path formation body 22 including a gas flow path 22c for supplying oxidation gas is superimposed. The first and second gas flow path formation bodies 21 and 22 have surfaces on which first and second separators 23 and 24 are superimposed, respectively.

The invention relates to a tire having a radial carcass reinforcement, consisting of at least one layer of metal reinforcing elements, said tire including a top reinforcement, which is covered radially with a tread, said tread being joined to two beads via two sidewalls. According to the invention, at least 85% of the metal reinforcing elements of at least one layer of the carcass reinforcement are unbanded metal cables, which in the so-called permeability test, have a flow rate less than 20 cm3/mn and at least 5% of the reinforcing element of said at least one carcass reinforcement layer are cables comprising at least one strand consisting of multifilament textile fibers.
