Abstract: The inner wall of a hub has a step surface between an upper bearing mounting surface and a magnet mounting surface. A spacer of ring-like shape is directly mounted to the step surface of the hub for determining the upper position of a rotor magnet. The inside diameter of the spacer is smaller than the inner wall at the bearing mounting surface of the hub so that a space is created between the bearing mounting surface, the spacer, and the bearing for holding a portion of adhesive. When a portion of the adhesive applied for bonding the bearing to the bearing mounting surface of the hub remains uncured, it will be retained in the space and prevented from entering the interior of the motor.

Abstract: A spindle motor having a housing, a hub member rotatable relative to the housing, a bearing disposed between the housing and the hub member, a rotor magnet mounted on the hub member, and a stator disposed in a facing relationship with the rotor magnet. The hub member includes a supporting wall portion, which cooperates with the stator to constitute an air seal structure. A magnetic fluid seal is provided at a position outward of the bearing, and includes a conductive plate for grounding static electricity. The bearing is comprised of a radial ball bearing, which includes certain improvement.

The hydrophobic polymer is disposed between the separator and conductive powder of the conductive layer to be out of contact with the active material layer.

Abstract: A lead storage battery having electro-collecting boards of lead or lead alloys, and active material layers closely contacted with the electro-collecting boards. The active material layers are integrally formed with the electro-collecting boards by providing a mixture, in the form of slurry, of an active material powder and a liquid to the electro-collecting boards, and then drying the mixture.

Abstract: A lead storage battery comprising a battery casing has a first case member (such as a tray) and a second case member (such as a cover) in a superposed relation. The tray has a protruding part for mounting one external terminal, and the cover has a protruding part for mounting the other external terminal. The tray and cover have recessed regions for receiving the protruding parts for mounting the external terminal of an opposing case member of the tray and the cover. The tray has a recessed region for holding a safety valve so that the safety valve is covered by the cover when the tray and the cover are superposed. A small hole is formed in the recessed region such that the small hole is connected with an interior of the battery casing.

Abstract: A lead-acid cell wherein current collectors (1, 5) constituting negative and positive plates opposed to each other with a separator (3) interposed therebetween which separator retains an electrolyte. One surface of each flat plate-like current collector (1, 5) has closely contacted therewith an active material layer (2, 4) having a net-like body embedded therein, and the current collector constituted of the active material layer (2, 4) and the current collector (1, 5) is disposed so that its side where the corresponding active material layer (2, 4) is formed is opposed to the separator (3).

Abstract: A novel process is provided for producing an improved electrode for an alkaline battery comprising the steps of adding an unsintered fluorocarbon resin powder to an active material powder and intimately mixing them together, applying a shear force to said mixture to thereby form agglomerates capable of retaining said active material powder in a network structure resulting from a fiber-formation of said fluorocarbon resin powder, adding an aqueous solution of a paste to said agglomerates, kneading them to mutually bind said agglomerates and thus forming a rubbery mass converting said rubbery mass into a sheet and attaching the sheet thus formed onto an electrically conductive core. The process provides an electrode having excellent reactivity and results in improved production efficiency.

Abstract: An alkaline battery is provided which comprises a positive and negative electrode separated by a separator, each electrode having a bare conductive portion at one end.
