Technical Examples
- A charging apparatus having a charging device for contact charging a rotatable member. The charging device rotates upon reception of a drive force from a drive force transmitting device. The axis of rotation of the charging roller and the axis of rotation of the photoreceptor drum intersect each other. It is a characteristic of the invention that a force received by the charging device from the drive force transmitting device and a force generated between charging device and the rotatable member are oriented in the same direction. With this arrangement, the thrust position of the charging device when the charging device is driven is stabilized.
- A serial charger with the function of automatic change of charging speed for NiCd/NiH batteries is provided where the different charging modes for multi-speed (four speed) charging process, two speed charging process or two speed charging process in two charging phases can be achieved by use of the speed-changing principle with a low power consumption of an exchange power unit. The finished charging time of each battery varies inversely as the number of the detected batteries to be charged. No matter whether the charging voltage is variable or constant, the charging current varies automatically to achieve the speedy charging process or the normal charging process even under low power consumption. Accordingly, an exchange power unit can be reduced in size and built in the charger so that the charger is convenient to carry and the finished charging time can be adjusted automatically according to the demand of battery consumption of customers.
- A method and system for locating mobile stations within a mobile communication network including at least two mobile stations and at least three base stations. Signal measurements are performed at the mobile stations and/or the base stations. Two or more mobile stations are located simultaneously by minimizing a cost-function, which is achieved by means of a sufficient number of equations, wherein the equations comprises the location of the mobile stations as a function of the location of one of the base stations in the network and the performed signal measurements.
- As outermost coating-like layer(s) of charging roller(s) is or are made to contact and/or slide against photosensitive drum(s), charge is applied from the outermost coating-like layer(s) to the photosensitive drum(s), charging the photosensitive drum(s). This being the case, resistance of the outermost coating-like layer(s) of the charging roller(s) fluctuates, and surface(s) thereof become scratched and so forth, and gradually deteriorate. Moreover, if remedial action is not taken, charging capability of the charging roller(s) may decrease, leading to nonuniformity in charging of the photosensitive drum(s) and causing lowering of image quality and/or reduction in service life of the photosensitive drum(s). The outermost coating-like layer(s) of the charging roller(s) is or are therefore periodically stripped off therefrom to rejuvenate the charging roller surface(s).
- The battery charging detects battery temperature and includes a temperature maintaining charging operation wherein average charging current is controlled to drive battery temperature to a holding temperature, and charging is performed while maintaining battery temperature at that holding temperature. In addition, a temperature increasing charging operation occurs prior to the temperature maintaining charging operation. The battery is charged with a current which raises battery temperature until the holding temperature is reached. When battery temperature rises to the holding temperature in the temperature increasing charging operation, charging can transition to the temperature maintaining charging operation.
