摘要： Disclosed is an apparatus for compensating mechanical loss produced in a load moving or transporting machine in which the load can be moved by a small external force as if the load were positioned in a space free from gravity or graviational influence by constantly producing a force from an electric motor which is equal to the weight of the load suspended by the apparatus. A circuit for simulating friction produced upon movement of the load is provided in a torque control circuit for the motor, wherein torque command signal for the motor is divided into a torque command signal corresponding to the weight of load and a torque command signal component corresponding to the friction produced as the load is moved and thereafter is applied to the torque control circuit for the motor.

摘要： A motor (16) for driving a garage door is controlled by a control unit, which counts the time required for the garage door (6) to move between an upper limit switch (202) and a lower limit switch (203). The control unit sets a comparison reference time on the basis of the time thus counted, and controls the motor (16) in such a manner that the motor driving does not continue for a period of time longer than the comparison reference time.

摘要： An automatic door operation control apparatus id disclosed which comprises a door operating device, a driving device for opening and closing the door, a condition detector for detecting a condition under which the movement of the door by the driving device is required to be discontinued, and a main control device for issuing a driving command to the driving device to actuate the same as required in response to a condition detection signal from the condition detector. The apparatus further comprises an auxiliary control device for stopping the operation of the driving device in the event that the main control device fails to issue a command to the driving device to stop the door movement within a predetermined length of time in response to the condition detection signal from the condition detector.

摘要： A temperature control device for a fixing heat source of a copying machine includes circuits for supplying power to the fixing heat source in synchronism with the zero-cross point of an a.c. signal applied from an a.c. power source. The device functions to supply the full-wave current to the heat source until a first predetermined temperature is sensed by a temperature sensor, to supply the half-wave current to the heat source until a second predetermined temperature is then sensed, and to change the duty factor of the half-wave current after attainment of the second predetermined temperature, thereby maintaining constant the temperature of the heat source with high accuracy.

摘要： A motor driving a garage door is controlled by a controller, and the rotation of the motor in the normal and reverse directions is normally controlled in response to an actuating signal applied to the controller from a main push button switch. In a specific-mode in which an actuating signal is applied to the controller from an emergency push button switch, a mat switch or a fire sensor, the latter signal has priority over the former signal, and the motor is driven to move the garage door to its full-open position.
