  • Patent number: 9319339
    Abstract: The communication system includes: first terminal devices connected to a transmission path and having terminal information; a second terminal device connected to the path and sending an information request requesting the information from the first terminal device; a first superimposing apparatus interposed between the first terminal device and the path; and a second superimposing apparatus interposed between the second terminal device and the path and receiving the request from the second terminal device. The first superimposing apparatus acquires the information from the connected first terminal device at predetermined timings and stores it. Upon receiving the request, the second superimposing apparatus sends the request to the first superimposing apparatus using a superimposed signal superimposed on a transmission signal transmitted via the path. Upon receiving the request, the first superimposing apparatus sends the information to the second superimposing apparatus using the superimposed signal.

  • Patent number: 8824939
    Abstract: An image forming apparatus includes an image bearing member; a rotatable belt member; a rotatable supporting roller for stretching the belt member; and a steering roller controlled by motors for stretching the belt member and for moving the belt member in a widthwise direction by an inclining operation. A number of sensors detect the position of the belt member in the widthwise direction and produce an output, causing a first controller to change the amount of the inclining operation of the steering roller in order to counter the force moving the belt member in the widthwise direction. The output of the sensors also causes a second controller to change the amount of the inclining operation of the steering roller in short intervals to reduce the rapid positional deviation of the belt member attributable to the inclination of the steering roller.
