A rechargeable lithium-ion button cell battery having a sealed housing includes a top flat plate and a round or oval cup sealed by laser at the rim of top plate whereas connecting the opening end of the cup sidewall. The top plate has a centered sandwiched structure including two outer plates at upper and lower position, that clamping one inner pin-like conductive plate by its flange, insulated by a gasket. The upper plate of the outer plates has an asymmetric shape to its center line, which allows asymmetric sealing force applied on the inner pin-like plate flange to act as a safety vent. Inside the sealed housing the anode and cathode electrodes are either spiral wound or stacked with separator to be a round or oval roll, one electrode is connected to the cup, the other electrode is connected to the inner pin-like conductive plate of the top plate.

A transmission shaft assembly for use in a sequential test of flexible thin-walled bearings includes a power connecting member, a clamping device and a plurality of bearing mounting kits. The bearing mounting kits are located between the power connecting member and the clamping device. The clamping device penetrates a central bore of each of the bearing mounting kits and is connected to the power connecting member. The power connecting member, the clamping device and the bearing mounting kits are connected into one piece. The power connecting member includes a spindle shank and a blind rivet. The bearing mounting kit includes a bearing mounting sleeve seat, a rear retaining ring, a front retaining ring, a bearing locking bolt and a tightening nut. The clamping device includes a clamping bolt, a washer and a spring washer.

Customer premise equipment

The present invention discloses a fault diagnosis and life testing machine for a flexible precision thin-wall bearing (), including a rack, and an axial loading device, a main driving device, a bearing mounting device, a clamping tooling, a data acquisition device, a hydraulic and a pneumatic auxiliary device which are provided on the rack. The main driving device is connected to a rear side of the axial loading device, and the clamping tooling is arranged at a front side of the axial loading device, for clamping the thin-wall bearing () onto the bearing mounting device. The data acquisition device is arranged in the axial loading device and at a side of the rack, the hydraulic and pneumatic auxiliary device is arranged at a side of the rack, and the axial loading device and the main driving device are connected by a pipeline. This testing machine can apply dynamic and static loads to the precision flexible thin-wall bearing (), can realize measurement of a bearing vibration, a bearing temperature, a bearing rotation progress and a rotation speed, and has advantages such as clever structure, perfect test function and relatively high test accuracy, safe and reliable detection process, and highly feedback results.

A mobile terminal includes a rear housing, a display screen and a camera. The rear housing includes a first shell and a second shell. The second shell can be slid relative to the display screen and can be stopped at a first position and a second position. The camera is arranged on the second shell, and an orientation of a light incident surface of the camera is the same as that of the display screen. In the first position, the first shell contacts the second shell to jointly bear the display screen and enable the rear housing to be of an opened-box shape, and the camera is located inside the mobile terminal. In the second position, the camera can be exposed from the mobile terminal.

A rechargeable lithium ion button cell battery having a sealed housing comprises an inner casing and an outer casing, both casings have at least one flat area as top or bottom of the battery, and a round or oval sidewall vertically formed to the flat area. An insulation gasket is positioned between the sidewalls, and the outer casing opening is mechanically crimped to complete the seal of the battery. Inside the sealed housing the anode and cathode electrodes are spiral wound with separator to be a round or oval roll. A roll axis is vertical to the flat area of the casings. The two electrodes are tapered in width to fully utilize the inner space. The electrodes comprise current collectors of metal foils coated with lithium-intercalating active materials, leaving small area of uncoated metal foils as conductor tabs for connecting the electrodes to the casings.
