  • Patent number: 10707625
    Abstract: In a typical connector, multiple terminals are not arranged at regular intervals on the same plane. Thus, impedance matching for transferring a high-frequency electric signal cannot be established, leading to problems such as lowering of high-frequency characteristics. For solving these problems, a connector is provided. The connector is a substrate-side connector including multiple terminals arranged in parallel on the same plane and bent at bent portions, an insulator configured to hold the multiple terminals, and an outer conductor shell configured to house the insulator. The substrate-side connector is configured such that a change in a terminal interval at each bent portion of the multiple terminals is reduced, and therefore, influence on the high-frequency characteristics (e.g., a return loss) due to impedance matching disturbance can be reduced.

  • Patent number: 10697803
    Abstract: To reduce information used for processes of complementing a missing detection pulse of a magnetic field detecting section, the apparatus carries out the processes of storing, as rotation direction information of a movable section 43, “rightward direction”, “leftward direction”, “unidentified” and “unidentified inversion”, and setting the rotation direction information to “unidentified” when recognizing a missing detection pulse, and subsequently, adjusting a rotation change amount of the movable section using a first adjustment value if the rotation direction information becomes the “unidentified” and adjusting the rotation change amount of the movable section using a second adjustment value if the rotation direction information is updated from the “unidentified” to the “rightward direction” or the “leftward direction”.
