  • Publication number: 20230056684
    Abstract: A terminal function device and a proxy transfer agent device generate, on mutually-connecting physical lines, logical paths to be correlated with physical port transmitting/receiving units. In a case of receiving a signal received at one of the physical port transmitting/receiving units, the terminal function device sends the signal out to a logical path corresponding to the physical port transmitting/receiving unit that received this signal. In a case of receiving a signal through the logical path, the proxy transfer agent device correlates the signal with information identifying the physical port transmitting/receiving unit corresponding to the logical path that received this signal, and transfers the information along with the signal. Ina case of sending out a signal to the logical path, the proxy transfer agent device sends out the signal to the logical path corresponding to the physical port transmitting/receiving unit specified as a transfer destination of the signal.

  • Publication number: 20220357526
    Abstract: There is provided an optical fiber array that can be easily optically connected to cores of optical waveguides on a connection counterpart substrate without requiring a complicated fabrication process to the connection counterpart substrate and laborious diffusing fusion of the cores. In an array, coating-removed exposed portions of fibers are attached to grooves that are provided on a lower substrate in order to position the optical fibers. Further, the exposed portions are pressed by a lid. Coated portions of the fibers are placed on a flat surface of a concave portion that is provided on the substrate to form a step with the grooves in a state where the exposed portions are attached. Front end parts of the exposed portions of the fibers each have a light collecting portion that collects light beams passing through an inside of the corresponding fiber to reduce an MFD.

  • Patent number: 11419250
    Abstract: A noise suppression sheet comprises a non-magnetic metal layer, a plurality of metal magnetic layers, and a plurality of insulating layers, and the metal magnetic layer and the insulating layer are alternately laminated on the non-magnetic metal layer. The noise suppression sheet can absorb and suppress noise generated from a circuit or the like in an electronic component by being mounted on the electronic component or the like. In the noise suppression sheet, noise is absorbed by each of the metal magnetic layers. Noise that is transmitted without being absorbed by the metal magnetic layer can be reflected by the non-magnetic metal layer and can be absorbed again by the metal magnetic layer, and hence the noise suppression sheet can suppress noise effectively.
