  • Patent number: 11152731
    Abstract: The present invention provides a contact capable of suppressing an increase in a DC resistance value for a long period and a method of manufacturing the same. The contact includes a base portion and an elastic contact portion. The elastic contact portion includes a planar portion configured in a planar shape; and a projection portion that is disposed on one surface of the planar portion and protrudes from the one surface. The elastic contact portion is configured to come into pressed contact with the second surface at the projection portion. The projection portion is configured such that a dimensional ratio H/L of the height H to the length L satisfies 0.25?H/L?0.44, where H is a height in a direction perpendicular to the one surface and L is a length in a direction parallel to the one surface.

  • Publication number: 20210288721
    Abstract: A receiving unit (2020) generates a received frame from a modulated optical signal. The modulated optical signal is generated such that a transmission symbol is generated by mapping an encoded bit string obtained by encoding a transmission bit string to an m-dimensional symbol space, a transmission frame is generated by mapping the transmission symbol to an n-dimensional frame space (n<m), and an optical carrier wave is modulated by using the transmission frame. A converting unit (2040) generates candidate vectors (m-dimensional vectors belonging to a partial symbol space within the symbol space) by using a received frame. A first computing unit (2070) computes a probability of that the transmission symbol belonging to the partial symbol space is transmitted for each partial symbol space. A second computing unit (2080) computes a log-likelihood ratio of each bit of the encoded bit string by using the probability.
