Abstract: An image forming apparatus includes an error detection unit, a determination unit, an output unit, and a power source control unit. The error detection unit detects an occurrence of an error in printing operation. The determination unit determines whether or not to perform power-off operation based on a detection result of the error occurrence detected by the error detection unit. The output unit outputs an error content of the error where the determination unit determines to perform the power-off operation.

Abstract: A permanent magnet rotary motor is provided in which cogging torque can be reduced and an increase in copper loss can also be prevented. A first divided core unit 13 is combined with a second divided core unit 15, thereby constituting a stator core 9. The first divided core unit 13 constitutes a yoke portion 17. The second divided core unit 15 includes pole pieces 25, magnetic pole surface constituent portions 27, and first and second type connecting portions 29A and 29B each mutually couple two adjacent magnetic pole surface constituent portions 27, all of which are formed integral with one another. The thickness of the first type connecting portions 29A in a radial direction of the stator core 9 is set to be smaller than the thickness of the second type connecting portions 29B in the radial direction of the stator core 9.

Abstract: A cylinder-type linear synchronous motor including a stator of which assembling is facilitated. A movable element is constructed by fitting annular permanent magnets on a magnet mount 29 fixed on a direct-acting shaft so that N and S poles are alternately arranged in an axial direction thereof. A plurality of stator core units 35 fixed in a frame so as to be spaced from each other at equal intervals in a peripheral direction of the movable element. The stator core units each constituted by combining a plurality of stator core divisions with each other. Exciting windings each are constituted of an annular winding formed by annularly winding a conductive wire so as to surround the movable element in the peripheral direction thereof. The annular windings each are fitted at a part thereof in a slot formed between each axially adjacent two of magnetic pole sections of the stator core units.

Abstract: A method of operating, controlling, monitoring and analyzing data of control devices used in the manufacturing devices or equipment of a factory automation system is disclosed. According to the method, the system controls itself and executes operations by reading as necessary in real time data in the form of files saved on a memory medium of each type of control device used in manufacturing devices or equipment.
