Abstract: A terminal arrangement device electrically connects an electric device, which is received in a housing, to an external device, and includes a first connecting terminal fixed to the housing. The first connecting terminal has a first supporting portion and a second supporting portion which are elastically deformable such that an output terminal of the electric device is supported between the first supporting portion and the second supporting portion. The first supporting portion has a flexural rigidity which is different from a flexural rigidity of the second supporting portion.

Abstract: A position detection device detects a position of a rotating body that is provided around a predetermined axis center with respect to a fixed body. A target is fixed to the rotating body. An inductive coil is fixed to the fixed body at a position facing the target in an axial center direction. The transmitting and receiving circuit applies an alternating current to the inductive coil and detects a position of the target. A magnetic circuit section is formed around the axis center and is fixed to the rotating body. A magnetic detection section is fixed to the fixed body and provided in region on a radially inner side than an inner circumferential surface of the magnetic circuit section. The target, the inductive coil, and the receiving and transmitting circuit constitute an inductive sensor, and the magnetic circuit section and the magnetic detection section constitute a magnet-type rotation angle sensor.

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: A position detecting device has an output circuit, which controls voltages of signal lines connecting a power supply and a ground by a power side transistor and a ground side transistor. An output signal line connects a connection point of the signal lines and an output terminal. A first comparator circuit outputs a signal “1” when a current flowing in the line between the power supply and the connection point is larger than a normal current flowing into the ground from the power supply in a normal state. A second comparator circuit outputs a signal “1” when a current flowing in the line between the connection point and the ground is larger than the normal current. When the signal “1” is output from the first comparator circuit or the second comparator circuit, a cutoff circuit turns off a switch disposed in the output signal line.
