Abstract: A developing device effects desirable development when the amount of charging of toner, q (C/g), the amount of toner deposited on the surface of a developing roller per unit area, m (g/cm²), the speed of movement of the surface of the developing roller, v (cm/sec), the available length of the developing roller, ℓ (cm), and the magnitude of electric resistance between the surface of the developing roller and a power source for developing bias, R (Ω), are adjusted so as to satisfy the formula, |q|m ≦ 100/vℓR. The developing device produces a developed image desirable in quality and free from background fogging when the magnitude of a developing electric current, I (A), is adjusted so as to satisfy the formula, R ≦ 200/1. Further, when a charging device (53), an electrostatic latent image forming device (55), a transfer device (59), a cleaning device (61), a discharge device (63), a charging and cleaning device, and electrostatic latent image forming and cleaning device, a developing and cleaning device, or a discharging and cleaning device is provided with an elastic electroconductive roller (21) composed of an elastic roller base (23) and a flexible conductor layer (25), the device is allowed to decrease size and lower price, curb the decline of capacity due to protracted use, and preclude the occurrence of dispersion of characteristic, efficiency, or performance.

Abstract: Known commutation methods for DC motors, e.g. with the aid of Hall elements, have disadvantages such as a wave-shaped torque, low efficiency, axial vibration and no smooth transition in the case of acceleration and braking. As a result of the application of a rotary field with voltages which are phase-displaced sinusoidally with respect to one another to all the coil carriers of a motor, the faults described in 2.1. are avoided.

Abstract: An electronic control system for scheduling gearshifts in a four speed automatic transmission includes storing in electronic memory accessible to a microprocessor, six functions relating vehicle speed to throttle position, one function being related to each upshift and downshift. Gearshifts are made by probing computer memory with current values for throttle position and vehicle speed, and determining on the basis of the stored shift schedule whether an upshift or downshift is required. Upshift points are determined also on the basis of the maximum engine speed when a wide open throttle condition is detected. Ambient barometric pressure alters the vehicle speed and engine speed attained at high altitude in comparison to those speeds that result for the same throttle position at sea level. Therefore, shift points defined by the schedule on the basis of vehicle speed and throttle position, and shift points related to wide open throttle conditions and engine speed, are corrected for altitude or barometric pressure changes from a reference barometric pressure at which the shift points are determined for the functions stored in computer memory.

Abstract: The invention relates to a process for selective absorption of chlorine and/or bromine from CO2-containing waste gases. The waste gas must contain at least 1 mol of SO2 per mol of Cl2 and/or per mol of Br2; if necessary, such a quantity of SO2 is added to the waste gas that the said relative quantity is present. For the absorption of the chlorine and/or bromine, the waste gas is mixed with steam and the mixture is then cooled until the steam condenses. An example of suitable apparatus is an upright pipe with an internal cooling coil.
