摘要： In an electrophotographic apparatus, densities of toner images of a light reference mark and a dark reference mark are detected by a density sensor, and input voltages such as an illumination power source voltage and an electrostatic charge voltage are varied by small values on the basis of a difference between detected densities and an aimed density, the small values are determined on the basis of a predetermined qualitative model. Subsequently, a line width of the toner image of a reference mark having a striped pattern is detected by a line width sensor and a developer bias voltage is varied by a small value in a similar manner as mentioned above.

摘要： This invention relates to an image forming apparatus provided with a punching unit and a paper refuse collecting box (container). The apparatus has a controller provided with a counter and monitor. The counter counts the total number of binder holes formed in paper by a punching operation by multiplying the number of sheets of paper to be punched by the punching unit with the number of binder holes formed in one sheet of paper that is designated by an operator. The monitor converts the total number of binder holes calculated by the counter into the amount of paper refuse accumulated in the container each time the punching operation is finished, while integrating the amount of paper refuse accumulated in the container. When it is judged that the integral value exceeds a predetermined maximum value, the controller causes a display device to display the necessity of emptying the container.

摘要： A control system for an induction motor of the present invention independently commands the torque current component and the exciting current component of a stator current group supplied to the stator of an induction motor so as to feed-back control the amplitude and phase of the stator current group. The torque current component is commanded to control the output torque of the induction motor in correspondence with the output of a steering force sensor for detecting the steering force. According to an electric power steering apparatus using an induction motor controlled by the control system, a permanent magnet is not used for the motor so additional equipment such as a clutch is not required. Consequently, the structure can be simplified and the size of the unit can be reduced. Further, manual steering operation can be performed in the case of failure.

摘要： A torque current component and an exciting current component of primary AC currents which are supplied to a stator of a three-phase induction motor are commanded independently of each other in accordance with a command rotational angular velocity and a rotational angular velocity of the three-phase induction motor rotating an agitator, and the rotational angular velocity of the three-phase induction motor is controlled by changing the magnitude and frequency of each of the primary AC currents. Furthermore, a test operation is carried out by giving the command angular velocity so as to make constant the angular velocity of the motor, and the laundry amount is estimated corresponding to an output torque of the motor in the test operation.

摘要： A method for readily measuring each motor parameter with high precision, with an induction motor at rest, and an apparatus for controlling the induction motor using these motor parameters are provided. The induction motor is set to a single-phase feed state or a feed state equivalent to that state. First, a stator resistance is measured from a current value and a voltage value at the time when a direct current command is given. Then, the current command of a current having an appropriately high frequency and a known current differential value is given to find a rotor resistance and a leakage inductance from current values and voltage values at two different times and the previously obtained stator resistance value. Then, the current command of a sine wave current having an appropriately low frequency is given to find a mutual inductance using the current value and the voltage value at the time. These measured values are used for a slip frequency operation and a speed estimation operation.
