Abstract: A position detector apparatus includes a detector part, wiring, a resin part, a resin body, a terminal, and a lead frame. The resin part has a thickness at a wiring side portion of the detector part that is greater than a thickness on a side opposite to the wiring side portion. Therefore, when injection-molding the resin part, due to a thickness change of the resin part, the detector part is pressed against a metal mold and a position of the detecting part is fixed. Further, the resin body has a thick-resin portion and a thin-resin portion. The thickness of the thin-resin portion allows a predetermined amount of dislocation of the detector part. Therefore, if the detector part is exposed, water is prevented from intruding the lead frame and the terminal.

Abstract: A fluid circulation circuit includes a flow passage switching valve. The flow passage switching valve includes a body and a switcher. The body includes a first inlet, a second inlet, and outlets including a first outlet. The switcher is capable of switching a passage configuration to a state in which a fluid that has flowed in from the first inlet flows out of either one of the outlets and a state in which the fluid that has flowed in from the second inlet flows out of either one of the outlets.

Abstract: A valve device includes a housing, a stationary valve and a drive valve. The stationary valve is placed in a fluid passage of the housing. The stationary valve forms a first passage, which conducts fluid, and a penetrating chamber which penetrates through the stationary valve in the axial direction. The drive valve is placed on one axial side of the stationary valve in the fluid passage and forms a second passage which conducts the fluid. The drive valve communicates the second passage to the first passage through rotation of the drive valve. The housing has a bottom portion that covers the penetrating chamber from another axial side. An upstream passage of the fluid passage, which is located on an upstream side of the drive valve and the stationary valve in a flow direction of the fluid, is communicated with the penetrating chamber through a communication passage.

Abstract: A valve device includes a housing, a flow hole forming portion and a rotor. The housing has a passage for fluid. The flow hole forming portion is fixed at the passage and includes: a plurality of flow holes, each of which is configured to conduct the fluid; and at least one partition which is placed between corresponding adjacent two of the flow holes. The rotor includes a passage opening and a closing portion. The at least one partition of the flow hole forming portion has: a parallel portion which extends in parallel with a radial direction of an imaginary circle centered on a rotational axis; and a progressively varying portion which is placed on an outer side of the parallel portion in the radial direction. A width of the progressively varying portion measured in a circumferential direction is progressively increased toward the outer side in the radial direction.

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 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.
