摘要： A motor controller controlling a rotational speed of a motor and including a thermal detector, a capacitor, an operational amplifier (OP), a charging/discharging circuit, a flip-flop and a logic circuit. The thermal detector detects environmental temperature of the motor to set a first reference voltage. The capacitor has one terminal coupled to a second reference voltage while another terminal thereof is charged/discharged by the charging/discharging circuit, controlled by a pulse width modulation (PWM) signal, to provide a third reference voltage. The OP compares the first and third reference voltages and outputs the comparison result to a ‘set’ terminal of the flip-flop. The flip-flop further uses a ‘reset’ terminal to receive a clock signal and the output signal thereof is utilized in generating the PWM signal. The PWM signal is further provided to the logic circuit for setting a duty cycle of a driving current of the motor.

摘要： A temperature control apparatus for a pulse width modulation (PWM) device. The temperature control apparatus includes a temperature detector installed around the PWM device for detecting a present working temperature of the PWM device, and a temperature comparator coupled to the temperature detector and the PWM device for comparing the present working temperature with a maximum limiting temperature and a minimum limiting temperature.

摘要： The present invention relates to a control system for establishing and maintaining a desired uniform temperature in a room heated by a heating device. The control system includes a valve assembly for controlling the pressure of the fluid supplied to the heating device, the valve assembly including a valve actuator, a pressure sensor sensing the pressure of the fluid supplied to the heater, and a temperature control device to sense the ambient temperature of the room. The control system also includes an electronic control unit connected to the aforementioned elements, the electronic control unit including an electronic circuit which samples nullopennull and nullclosenull input signals from the temperature control device, determines the rate of change of the pressure of the fluid from a predetermined pressure set point, and varies the pressure set point (which thereby varies the heating device output), according to the nullopennull or nullclosenull signals by providing a command signal to the valve actuator. This command signal is based upon a difference between the predetermined desired temperature and the actual temperature, and the rate of change of the pressure of the fluid.

摘要： Feature is a fixing device equipped in an image forming device enabling reduction of electronic noise and preventing hot-offset and fixing disorder. The fixing device includes a rotatable fixing roll, a heater for heating the fixing roll, a temperature detector for detecting the surface temperature of the fixing roll, and temperature control circuitry. The temperature control circuitry is for controlling the fixing roll surface to maintain a predetermined temperature by supplying a predetermined electric power to the heater, wherein the temperature of the fixing roll during continuous image forming operation is detected periodically by the temperature detector, and in correspondence to the difference between a fixed reference temperature and the detected temperature, controlling the electric power quantity to be supplied to the heater during a cycle by increasing or decreasing a half-wave unit cycle number of the commercial power source.
