摘要： A process control apparatus of electrophotographic apparatus has an optical sensor for optically detecting the density of toner patches formed on a photoreceptor drum. The present apparatus is further provided with a control device for controlling lamps for the copying process, chargers and other elements. A toner patch is formed on the photoreceptor so as to be located between every two toner images for a copying operation. The control device controls the lamps, chargers and other elements in accordance with the result of the toner patches detected by the optical sensor so as to stabilize the copying picture quality. With the arrangement, it is avoided that the job efficiency during the copying operation deteriorates, and the control data obtained from the toner patches is soon used for the toner image formation for the copying operation, thereby ensuring that the process control improves in accuracy.

摘要： An apparatus includes a system controller which calculates a ratio of a first signal to a second signal and adjusts a control parameter of an electrophotographic reproduction process so that the density of fog indicated by the ratio is within a predetermined range. A first optical sensor outputs the first signal by detecting a reflectance of a non-image area on the photoreceptor between a developing unit and a transfer charger. A second optical sensor outputs the second signal by detecting a reflectance of a surface of the photoreceptor between a cleaning unit and a charger. The system controller controls developer including toner and carrier to be agitated when the ratio obtained after adjusting the control parameter is still outside the predetermined range. Since the density of fog is detected with accuracy by calculating the ratio, copy quality is stabilized even when temperature changes. Moreover, even if the ratio is outside the predetermined range as a result of the supply of toner which has deteriorated due to a heat history, the deterioration of toner is restored by agitating the developer. It is thus possible to prevent copy quality from being degraded.

摘要： The present invention provides a process control stabilizing system including a cleaning device for the corona wires which allows the process control to be carried out optimally based on exact information which is obtained by certain sensors while a discharge from the main charger unit is kept uniform. The system is constructed so that an electrode cleaner is activated before the detection of the surface potential and/or the detection of the optical density, and in addition, the cleaning operation will be operated until the detection result falls within a predetermined range. Alternatively, the system causes detection of the surface potential and/or detection of the optical both before and after a cleaning operation by the electrode cleaner. The cleaning operation will be repeated until the difference between the first and second detections falls within a predetermined range. In the above operations, if the repetitions of the operations in excess of the predetermined number of times cannot make the detection result fall within the predetermined range, the system preferably activates a warning device and/or prohibits a copying operation.

摘要： Output of each sensor arrangement is supplied to an ECU through a communication bus line. A value of a turning radius of a vehicle, which is used for adjusting directions of optical axes of swivel lights, is computed based on the output of each sensor arrangement in the ECU. When a majority of the computed values fall within a predetermined allowable range, the majority of the computed values are determined as normal, and the remaining of the computed values is determined as abnormal. The communication bus line is determined as abnormal when none of the output from the sensor arrangements is obtained. An optical axis control angle is computed based on the normal computed values and is used to drive actuators to adjust directions of the optical axes of the swivel lights.

摘要： In a vehicle headlight optical axis adjusting apparatus, inter-vehicle distance in each of divided zones is detected by a laser radar device. Desired optical axis raising angles for a vehicle headlight are calculated based on these inter-vehicle distances of the divided zones. The optical axis of the headlight is adjusted to the most downward pointing angle selected from among these angles, so that a driver of a preceding vehicle is not blinded.

摘要： In a discrimination mode for discriminating a track density mode of an FDD using a carriage mechanism of the lead screw type, on the basis of a reciprocal seek operation of a magnetic head, when a carriage is moved a seek distance dependent on a track density in a forward seek mode, the drive of the carriage mechanism can reliably be stopped. This realizes a reciprocal seek operation of the head that depends on a track density mode of the FDD. Accordingly, a host computer compares the number of pulses contained in a STEP signal in a forward seek stroke with that in a reverse seek stroke, and reliably discriminate a track density mode of the FDD on the basis of the comparison result.
