摘要:
An apparatus and method for controlling the velocity of a motor controls the motor by fuzzy inferential reasoning in a transitional period when the motor is started, changed in speed, reversed or stopped. Such fuzzy control eliminates an increase in the length of the transitional period caused by a limitation in supply current under conventional PLL control and makes possible a rapid transition to a target velocity. A plurality of fuzzy rules are provided and one of these fuzzy rules is selected in accordance with the length of the previous transitional period, thereby suppressing the effects of load fluctuation and the influence of a fluctuation in torque caused by a rise in temperature. Therefore, the length for transitional control of a motor can be shortened and the apparatus can be reduced in size.

An equipment control unit is composed of equipment control means for controlling the operation of an equipment, communication control means for controlling the transmission and reception of data to and from an external device, and transfer means for transferring the data between the equipment control means and the communication control means.
摘要:
A power supply control apparatus includes an input device for receiving data from a machine, the data being indicative of a condition of a malfunction occurring in the machine; a communication device for communicating between the input device and an external apparatus installed at a position separate from the machine; and a power supply control device for controlling a supply of electric power to the machine. The communication device transmits the received data to the external apparatus, and based on the malfunction condition indicated by the data, the external apparatus transmits an instruction to the communication device to interrupt the supply of power to the machine. The power supply control device interrupts the supply of power to the machine in accordance with the instruction from the external apparatus.
摘要:
A method of managing an image forming apparatus by a remote computer comprises the steps of detecting an abnormal state in the image forming apparatus, transferring an error code corresponding to the kind of the detected abnormal state to the computer, selecting a predetermined program according to the transferred error code by the computer, transferring the selected predetermined program to the image forming apparatus by the computer, and executing the transferred predetermined program by the image forming apparatus. The predetermined program is a diagnosing program to examine the causes of a failure in the image forming apparatus.
摘要:
An image processing apparatus comprises: an inserting unit to insert a memory medium such as IC card or floppy disc which can be freely attached or detached and in which programs to control the image processing apparatus have been stored; a memory to store the program which has been read out from the memory medium and kind data indicative of the kind of program; a loading circuit to load the program stored in the memory medium into the memory; and a control unit to control the image processing apparatus in accordance with the program stored in the memory. In the case where the program has already been stored in the memory, the control unit controls the loading circuit in a manner such that when the kind data stored in the memory is the data indicative of a special program, the loading of the program from the memory medium to the memory is inhibited and, when the kind data stored in the memory is not the data indicative of the special program, the loading of the program from the memory medium to the memory is executed.
