Abstract: PURPOSE:To prevent an active substance from separating off from the core material even through reversals of expansion and contraction with changing/discharging by pulverizing a neg. electrode material such as a fusible alloy which can occlude and emit Li electrochemically, mixing with carbon to form No.1 layer, applying carbon coating to form No.2 layer, and thus accomplishing a two-layer structure. CONSTITUTION:A neg. electrode material consisting of a fusible alloy such as Al capable of occluding or emitting Li electrochemically is pulverized, and the resultant powder is mixed with carbon or subjected to a heat treatment in a gas atmosphere inch. oxygen, and thereby an oxide film is produced over the powder surfaces. Then No.1 layer 2a as a mixture with carbon and No.2 layer 2b formed by applying a C coating to one side of this No.2 layer 2a to accomplish a two-layer structure. Even in case a change in the shape is generated in the fusible alloy, Al, because of its repetition of expansion and contraction associated with charging/discharging, the powder of neg. electrode material is prevented from separating off from the core material 3.

Filed: 1991-11-21
Abstract: PURPOSE:To uniformize dispersion of thermal crown and wear of work roll at the time of continuous rolling by shifting work rolls in a state where the axial center of back-up roll is inclined to the axial center of work roll on the horizontal plane. CONSTITUTION:In the arrangement of a work roll 2 and buck-up roll 1 on the horizontal plate at the time of rolling, the back-up roll 1 is inclined to the work roll 2 on the horizontal plane at the time of rolling so that one end part of the back-up roll which is situated in the direction to which the work roll 2 is desired to be shifted is directed to the outlet side of the rolling mill with respect to the other end part and a shifting force is added. Since a thrust force acts on the work roll 2 toward that direction and frictional resistance is reduced by the amt. of thrust force in the case of shifting in that direction, small shift is enabled. And meandering of the rolled stock isn't generated and stable rolling is enabled even when the work roll 2 is shifted at the time of rolling.
