  • Patent number: 8957673
    Abstract: A rotational angle sensor and a method for manufacturing the same, and a throttle control device with a rotational angle sensor, which may lower the cost, are provided. The rotational angle sensor includes each sensor IC for detecting a rotational angle of a rotor based on a magnetic field generated between a pair of magnets respectively disposed across the rotational axis of the rotor; each main terminal connected with each connection terminal of each sensor IC; and a holder member for holding each sensor IC and connection portions of each main terminal on each sensor side. A sensor assembly is constructed to form the sensor ICs the main terminals and the holder member into an assembly. A potting material is potted into the holder member.

  • Publication number: 20140000734
    Abstract: A fuel delivery pipe may be designed such that, during a molding process of the fuel delivery pipe using a mold, a pressure of a molten resin for molding the fuel delivery pipe is applied to a main pipe portion core used for molding a main pipe portion of the fuel delivery pipe, so that the main pipe portion core is pressed against distribution pipe portion cores used for molding distribution pipe portions of the fuel delivery pipe.

  • Patent number: 8044659
    Abstract: A rotational angle sensor and a method for manufacturing the same, and a throttle control device with a rotational angle sensor, which may lower the cost, are provided. The rotational angle sensor includes each sensor IC 50(1), 50(2) for detecting a rotational angle of a rotor based on a magnetic field generated between a pair of magnets respectively disposed across the rotational axis of the rotor; each main terminal 61, 62, 63, 64 connected with each connection terminal 55, 56, 57 of each sensor IC 50(1), 50(2); and a holder member 90 for holding each sensor IC 50(1), 50(2) and connection portions of each main terminal 61, 62, 63, 64 on each sensor IC 50(1), 50(2) side. A sensor assembly 100 is constructed to form the sensor ICs 50(1), 50(2), the main terminals 61, 62, 63, 64 and the holder member 90 into an assembly. A potting material 102 is potted into the holder member 90.
