Abstract: A sensor module is adapted to be attached to an actuator body incorporating an electric actuator. The sensor module includes a sensor assembly, a sensor cover, and a connector housing. The sensor assembly includes a sensor detection part and a sensor housing. The sensor detection part is configured to detect a physical change amount of a driven body driven by the electric actuator and to convert the physical change amount into an electrical signal. The sensor housing incorporates the sensor detection part. The sensor cover is provided separately from the sensor housing and is attached to the actuator body. The sensor module is configured integrally by attaching the sensor assembly to the sensor cover. A connector terminal electrically connected to a connection terminal of the sensor detection part is insert-molded in the connector housing. The connector housing is provided integrally with the sensor housing.

Abstract: A first opposing surface of a first yoke has a constant radius of curvature and has a center of curvature that lies on a center of rotation. At least two rotation direction end portions of a second opposing surface of the second yoke are formed such that toward either end in the rotation direction, the two end portions are increasingly spaced away from a reference curved surface in a direction away from the first opposing surface. The first and second opposing surfaces face each other to define a gap thereinbetween. Accordingly, the gap between the yokes is wider at its end portions than at its center, and increases in magnetic flux density flowing through a Hall element is curtailed at the end portions of the gap. Further, it is not necessary for the first yoke to protrude outward when widening the end portions of the gap.

Abstract: A rotation angle detection device includes a magnetic field generation section, a yoke, and a magnetism detection section. The magnetic field generation section has a first end portion and a second end portion. The yoke has such a tube shape that the magnetic field generation section and a rotation axis of a rotating body are located therein. The yoke has a gap at a part in a circumferential direction in a cross section perpendicular to the rotation axis. The magnetism detection section is disposed in the gap and outputs an electrical signal in accordance with a magnetic field strength in the gap. The magnetic field generation section is disposed in such a manner that a magnetic force line passing through the magnetic field generation section passes through the rotation axis regardless of the rotation angle of the rotating body and the rotation axis passes through the first end portion.

Abstract: A rotation angle detection device has a first yoke, an inside surface of which is formed of a first concave curved surface and a second concave curved surface, and a second yoke, an inside surface of which is formed of a third concave curved surface and a fourth concave curved surface. Each concave curved surface does not extend in a second direction but extends toward a first flat surface or a second flat surface in an inclined manner. The first flat surface and the second flat surface face each other sandwiching a Hall element therebetween and are parallel to each other. The magnetic flux, which leaks from the first yoke into an inside space and reaches the second yoke, flows in the second direction over a wider area around the Hall element.

Abstract: A high-side output transistor and a low-side output transistor of an output circuit control voltages of conductors, which connect a power supply terminal and ground, and outputs a voltage signal to an output terminal through an output conductor. A voltage output circuit detects a voltage applied to the high-side output transistor based on a potential difference of a first resistor provided closer to the output terminal side. A comparator circuit outputs a signal to turn off a first switch and a second switch provided in the conductors, when the output voltage of the voltage output circuit exceeds a reference voltage Vr.

Abstract: A terminal insert article includes a metal terminal, and a resin molded article in which the terminal is inserted. The molded article is formed by injection molding. When a position of the molded article into which molten resin is injected at time of the injection molding is referred to as a resin injection position, the resin injection position is formed in a projecting shape. The molded article includes a spherical surface part at an opposite position from the resin injection position. The spherical surface part has a spherical surface shape swollen out in a direction away from the resin injection position. A component that constitutes a rotation angle sensor, which detects a rotation angle of a rotatably-supported shaft, is inserted in the molded article.

Abstract: The present disclosure provides a rotational angle detecting device. An IC substrate has a flat surface extending along a rotational axis of a throttle valve. Yokes forms, together with the magnets, a closed magnetic circuit. A first Hall element outputs a first signal according to the magnetic flux density in a first direction along the flat surface. A second Hall element outputs a second signal according to the magnetic flux density in a second direction intersecting the flat surface. The first and second Hall elements are positioned within a region that is surrounded by the magnets and the yoke and that is between an edge surface and an edge surface.

Abstract: An ECU loads detected values of a rotation angle sensor and a pressure sensor which are mounted to an electric throttle, and executes an abnormal-sensor determination control to determine whether one of the rotation angle sensor and the pressure sensor is abnormal. Specifically, the ECU determines that one of the rotation angle sensor and the pressure sensor is abnormal, in a case where a state that a tendency of the actual opening angle detected by the rotation angle sensor does not match a tendency of the pressure detected by the downstream pressure sensor has continued for a period greater than or equal to a predetermined period. Therefore, since the pressure sensor can replace the rotation angle sensor used for detecting abnormality in a conventional technology, two rotation angle sensors can be reduced to one rotation angle sensor, and a cost is reduced.
