Abstract: A method for using a lifting magnet and a lifting magnet. The lifting magnet includes a plurality of electromagnet coils that are each independently ON/OFF-controllable and voltage-controllable, and a magnetic pole that is excited by application of a voltage to the electromagnet coils. An electromagnet coil to be used for lifting steel plates is determined based on a total thickness of the steel plates to be lifted. An amount of passing magnetic flux ?r in the magnetic pole in a case where magnetic flux passes through only the steel plates to be lifted when the electromagnet coil is used is calculated. An application voltage to be applied to the electromagnet coil used for lifting the steel plates is determined based on the amount of passing magnetic flux ?r. The application voltage is applied to the electromagnet coil.

Abstract: In a system including a communication apparatus having a facsimile function and a relay apparatus connected to the communication apparatus via a communication network, a user directly operates the communication apparatus, thereby preventing the communication apparatus from executing inefficient processing in the entire system. The relay apparatus controls the facsimile function of the communication apparatus that has established communication with the relay apparatus to enable transmission and reception of image data. Furthermore, the relay apparatus restricts execution of the facsimile function of the communication apparatus other than facsimile transmission of the image data transferred from the relay apparatus.

Abstract: An image processor has a plurality of NICs (communication units), and a function of executing a plurality of jobs involving communication processes with terminals through the NICs. The job processing efficiency of the image processor is improved to the utmost extent. The types of priority jobs are preset for each of the NICs in priority job setting data, and the image processor carries out control so that a type of a job set to be given priority in the priority job setting data is processed in priority when a plurality of jobs involving communication processes through the NICs arise at overlapping timing. A job transmitter terminal transmits a job to the address of the NIC corresponding to the type of the job on the basis of the data that presets the corresponding relation between the types of jobs and communication addresses.

Abstract: In an image-forming section, a communication device is attached to the top surface of a developing cartridge that is detachably attached to a developing device, and a main body side communication device is attached to a copying machine main body in a manner so as to face the top portion of the communication device. When a loading operation of the developing cartridge to the copying machine main body is carried out, the main body side communication device detects this operation, and sends an electric wave for an electrical supply to the developing cartridge. The communication device transmits individual information of the developing cartridge by means of radio waves, and the main body side communication device receives, demodulates and reads this information. Based upon the results thereof, it makes a judgment as to conformity and suitability of the developing cartridge, and displays the results of the judgement or gives a warning as to the results.
