An electrode for a sealed nickel/metal hydride battery and a method of manufacturing the same, which is capable of suppressing a decrease in the charging reserve of a hydrogen-storage alloy electrode (negative electrode) and an increase in the internal pressure of the battery, is provided. The hydrogen-storage alloy electrode is formed using a tackifier or a binder which is prepared from an organic polymer material containing the ether linkage (--O--), for example, polyethylene oxide, polypropyl...

A sealed battery in which an opening of a battery case is sealed with any one of a sealing member via an insulating gasket, and a sealing unit in which a sealing member is crimped inside a filter via an inner gasket. The sealed battery includes a sheet-like gasket placed upon the sealing member so that the battery case is tightly sealed with any one of a combination of the insulating gasket and the sheet-like gasket, and a combination of the insulating gasket, the sheet-like gasket, and the inne...

Sealed bearing incorporating an inner race (13) an outer race ring (14) and a row of elongated rollers (15) disposed between, whereby races (11, 12) and rollers (15) have curved longitudinal section profiles and which rollers (15) are axially moveable between the races relative thereto for allowing mutual misalignment of the races, and whereby at least one sealing member (18) is formed separately, positioned axially outside the rollers (15) but adapted to follow the rollers (15) in a free-floati...

The present invention provides a battery, in which swelling or expansion of side surface of a battery case when the battery is charged is reduced. The invention provides a sealed battery, accommodating a battery element of flat shape, said battery element comprising a positive electrode and a negative electrode being laminated on each other with a separator interposed between them and being wound together, characterized in that a recessed portion is formed on a side surface of a battery case run...

A sealed case includes an elongated trunk member including an overlapped part made by overlapping parts of an inside end portion and an outside end portion apart from each other in a vertical axis direction of a sheet material and first and second end portions each provided with an opening and apart from each other. The overlapped part has a fixing area to fix the inside and outside end portions. First and second cover members are fixed to the first and second open end portions of the trunk memb...

A sealed battery includes a can for receiving an electric generator, a shape-variable plate crimped on an opening of the can, a gasket disposed between the can and the shape-variable plate, a fixing plate disposed under the shape-variable plate, an insulating member disposed between the shape-variable plate and the fixing plate, and a projection extending from the fixing plate and welded on the shape-variable plate. The projection is provided with a mechanically weak portion which is designed to...

A sealed battery includes a can for receiving an electric generator, a sealing member crimped on an opening of the can and connected to one of a positive electrode and a negative electrode of the electric generator, a gasket disposed between the can and the sealing member, a cover cap disposed on the sealing member with an insulating member disposed between the cover cap and the sealing member, a current control member disposed between the cover cap and the sealing member to cut-off a flow of cu...

A sealed bearing assembly for supporting a rotating shaft and, in particular, a crankshaft of a two-stroke engine includes an inner race, an outer race and a plurality of roller elements disposed between the inner and outer races. A grease seal is disposed between the inner and outer races and spaced axially outward from the roller elements along an axis of the bearing assembly. The grease seal includes a rigid support structure and a flexible sealing member attached to the rigid support structu...

A multilayer cell is provided that comprises two solid, nonporous current collectors, two porous electrodes separating the current collectors, a porous separator between the electrodes and an electrolyte occupying pores in the electrodes and separator. A thermoplastic vinyl acetate polymer or thermoplastic polyamide is applied to the multilayer structure; and pressure or heat is applied to seal layers of the cell by means of the thermoplastic vinyl acetate polymer or thermoplastic polyamide to f...

A gripper includes a body and an actuator coupled to the body. The gripper further includes a first hub rotatably mounted to the body where the first hub is drivingly engaged with the actuator. A second hub is selectively drivingly engaged with the actuator. The second hub rotates in a direction opposite to the first hub. A first arm is coupled to the first hub and a second arm is coupled to the second hub. The first and second arms are articulable from open position to closed positions.
