An image forming apparatus includes a memory unit configured to store image data, a mode detecting unit configured to detect a transition from a first operating mode to a second operating mode, and an encryption unit configured to encrypt the image data in the memory unit based on the transition.

Image forming apparatus

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 unitis combined with a second divided core unit, thereby constituting a stator core. The first divided core unitconstitutes a yoke portion. The second divided core unitincludes pole pieces, magnetic pole surface constituent portions, and first and second type connecting portionsA andB each mutually couple two adjacent magnetic pole surface constituent portionsall of which are formed integral with one another. The thickness of the first type connecting portionsA in a radial direction of the stator coreis set to be smaller than the thickness of the second type connecting portionsB in the radial direction of the stator core

Permanent magnet rotary motor

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,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,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.

Cylinder-type linear synchronous motor

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.
