A data processing apparatus has a first processing unit for processing an input data, a second processing unit responsive to the data processed by the first processing unit for executing a processing dependent on the data and producing a display data, and a display unit having a display drive unit and a display device for displaying the display data. The second processing unit is selectively inactivated and activated under control of the first processing unit to reduce power consumption in the second processing unit. The display drive unit is also selectively inactivated and activated under control of the first processing unit to reduce power consumption in the display unit. The display device has a memory function that maintains its display image even when supply of a display drive signal from the display drive unit is stopped, so that a latest image before inactivation of the second processing unit and/or the display drive unit for power consumption reduction is visible by an operator during the inactivated and low power consumption state of the apparatus.

A positive electrode active material powder for a non-aqueous electrolyte secondary battery, wherein an amount of a liquid reagent absorbed by the powder is 20 to 40 ml per 100 g of the powder when the liquid reagent is dibutyl phthalate, and the amount is 20 to 50 ml per 100 g of the powder when the liquid reagent is N-methyl-2-pyrrolidone or water, the absorption amount is a value measured using a device according to test method A or B regarding DBP absorption based on JIS K6217 (1997), and the measured value is an amount of the liquid reagent added until the viscosity of a mixture of the powder and the liquid reagent reaches a level corresponding to 70% of a maximum torque which is recorded when a change in the viscosity of a mixture of the powder and the liquid reagent is measured by a torque detecting device.

The present invention provides a lithium rechargeable battery including a negative electrode comprising a copper core material, to which is fixed an active material made by mixing artificial graphite particles A obtained by kneading and granulating a base material of pulverized bulk mesophase pitch with pitch in a softened state and/or thermosetting resin, carbonizing the resulting granules at 700 to 1,500&#xb0; C. and graphitizing the carbonized granules at 2,500 to 3,000&#xb0; C. with spherical graphite particles B having a high mean circularity, with a view to inhibiting the deterioration in battery capacity through the repeated charge/discharge cycles, which occurs remarkably in a high energy density lithium rechargeable battery, and providing excellent discharge characteristic and safety.
