Abstract: A magnetism sensing element is provided to be rotatable relative to permanent magnets and outputs a magnetic force detection value, which corresponds to a perpendicular component of magnetic flux. A Hall IC calculates and outputs an output voltage, which corresponds to a relative rotational angle between the permanent magnets and the magnetism sensing element, based on the magnetic force detection value outputted by the magnetism sensing element. The Hall IC calculates the output voltage as V2=k×arcsin(V1/(VM+α))+Voffset, in which V1, V2, VM, k, α and Voffset indicate the magnetic force detection value, the output voltage, a maximum value of the magnetic force detection value, a gain, a predetermined value and a predetermined offset value.

Abstract: In a position detector for detecting a position of a detection body, a signal processing circuit processes a signal outputted from a magnetic field detection element. A first storage circuit stores the signal outputted from the magnetic field detection element and outputs a signal to an external device through an output circuit in a normal operation mode. A second storage circuit stores an output value of the first storage circuit. When a malfunction determination circuit determines an instantaneous power interruption mode, a signal route changing circuit prevents a signal transmission between the first storage circuit and the second storage circuit and a signal transmission between the first storage circuit and the output circuit, prevents the second storage circuit from updating data for a certain period of time, and permits the second storage circuit in which updating is prevented to output a signal to the output circuit.

Abstract: A position detection device includes a magnetic detection element, a wiring, a first component and a second component as a first mold resin, a terminal, and a sensor cover as a second mold resin. The magnetic detection element can detect a change in magnetic field. The wiring is connected to the magnetic detection element. The first component and the second component mold the magnetic detection element and the wiring so that the wiring is exposed. The terminal is connected to the wiring. The sensor cover molds the first component, the second component and the terminal so that the first component and the second component where the magnetic detection element is located are exposed, and has a deformation suppressing portion. The deformation suppressing portion suppresses the deformation of the first component or the second component when the sensor cover is deformed.

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: A position detection apparatus includes a magnetic generator, a magnetic detector, a storage, and a rotation angle calculator. The rotation angle calculator calculates a relative rotation angle of the magnetic generator with respect to the magnetic detector based on a voltage output from the magnetic detector and a relational expression of θ=sin−1((VH−c)/V0)−b. In the relational expression, the relative rotation angle is defined as θ, the voltage output from the magnetic detector is defined as VH, a true maximum value of the voltage output from the magnetic detector is defined as V0, a first true correction value is defined as b, and a second true correction value is defined as c.
