  • Publication number: 20140028308
    Abstract: A magnetic sensor device includes a first magnet and a second magnet that are disposed on mutually opposing sides of a conveyance path, and one of poles of the first magnet faces an opposite pole of the second magnet. The first magnet and the second magnet generate a cross magnetic field whose strength in a spacing direction, which is orthogonal to a conveying direction, is within a predetermined range. An AMR element is located in a magnetic field in which the strength of the cross magnetic field in the spacing direction is within a predetermined range, and detects, as change in a resistance value, change in the cross magnetic field caused by an object to be detected. A multilayer board outputs the change in the resistance value detected by the AMR element to a processing circuit.

  • Patent number: 6891840
    Abstract: In a local area network path control system, hubs are connected in a ring and classified into two groups. Each of terminals has two LAN controllers. One of LAN controllers is connected to one of the hubs belonging to one of the groups while the other is connected one of the hubs belonging to the other group. One of the LAN controller is used as an active controller and the other is used as a standby controller. Each of the terminals has a destination information table registering destination IP addresses and destination MAC addresses of the other terminals. When the terminal detects failure occurring between the active controller and the corresponding hub, it changes the active controller from one to the other of the two LAN controllers. Furthermore, the terminal notifies a newly MAC address for communicating with the terminal to the other terminals.
