Abstract:
A lithium secondary cell includes an internal electrode body having a positive electrode plate and a negative electrode plate wound and laminated around an external peripheral wall of a hollow cylindrical winding core. The inside of the internal electrode body is impregnated with a nonaqueous electrolyte solution. A cylindrical cell case houses the internal electrode body and has open ends sealed with plate member electrode caps. An external terminal member protrudes onto the surface of the electrode caps to lead current to the outside of the cell case, and an internal terminal member connects with the internal electrode body to take current from the internal electrode body. An elastic body and at least two of the plate member, the external terminal member and the internal terminal member are joined together for construction. An assembly of lithium secondary cells is also disclosed.

Abstract:
A lithium secondary battery includes an electrode body obtained by winding or laminating a positive electrode and a negative electrode via a separator, and a non-aqueous electrolytic solution containing a lithium compound as the electrolyte. The non-aqueous electrolytic solution contains water (H2O) and hydrofluoric acid (HF) in a total concentration of 10,000 ppm or less. Owing to the restriction of the total concentration of water and hydrofluoric acid contained in the non-aqueous electrolytic solution, the lithium secondary battery can suppress the deterioration of battery properties caused by the water and hydrofluoric acid and has excellent cycle property and reliability.

Abstract:
A lithium secondary battery uses an organic electrolyte solution and includes a battery case, an internal electrode body contained in a battery case and including a positive electrode, a negative electrode and a separator made of porous polymer. The positive electrode and the negative electrode are wound or laminated so that the positive electrode and negative electrode are not brought into direct contact with each other via the separator. A zeolite having a moisture absorption characteristic, has been incorporated in the battery case so that the zeolite is brought into contact with the organic electrolyte solution within the battery case. The lithium secondary battery achieves suppression of deterioration of a charge-discharge cycle characteristic of a battery caused by decomposition of an electrolyte by limiting moisture mixed into an organic electrolyte solution to a considerably lower level as well as improvement of its self-discharge characteristic.

Abstract:
An apparatus (10) includes a plurality of parts which are clamped together by a fastener (24). The clamped parts include a reaction canister (16), an air bag (12) inside the canister (16), a retainer frame (60) inside the air bag (12), and a retainer sleeve (102 or 116) outside the canister (16). The fastener (24) extends through the retainer sleeve (102 or 116). The apparatus (10) further includes a deployment structure (18) supported for limited movement relative to the canister (16). A panel portion (70) of the deployment structure (18) extends across a deployment opening (48) in the canister (16). A mounting portion (72 or 74) of the deployment structure (18) projects from the panel portion (70). The retainer sleeve (102 or 116) extends through an aperture (96) in the mounting portion (72 or 74) of the deployment structure (18), and is spaced fully from the deployment structure (18) within the aperture (96). In this arrangement, clearance for movement of the deployment structure (18) is provided about the periphery of the retainer sleeve (102 or 116).

An apparatus (20) for attaching an air bag (22) and an inflator (24) to a vehicle steering wheel (26) comprises a mounting plate (28) which is connectable with the steering wheel. The air bag (22) has a mounting portion (44) which encircles an inlet opening (46) into the air bag. A bag ring (162) clamps the mounting portion (44) of the air bag (22) and a flange (104) on the inflator (24) between the bag ring and the mounting plate (28). Only three fasteners (168) substantially equally spaced about a central axis (C) of the bag ring (162) secure the mounting plate (28) and bag ring (162) together to clamp the inflator flange (104) and mounting portion (44) of the air bag (22) between the mounting plate (28) and bag ring (162).
Abstract:
A chucking device of a workpiece to be ground in a grinding machine, including a rotatable housing, a pair of elastically biased weight bodies which are opposed in the housing so as to come away from and close to each other a pair of opposed clamp plates which are provided on the respective weight bodies for relative movement and which have openings defining a center insertion opening in which the workpiece is inserted, and an end plate which is secured to the housing for covering the housing. The clamp plates are capable of inclining in planes thereof. The workpiece is firmly held in and by the center insertion opening of the clamp plates at at least four points of the center insertion hole by the outward displacement of the weight bodies, due to the centrifugal force acting thereon when the chucking device rotates.
