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.

Abstract: A communication apparatus operates with a supply voltage of a power and transmits a sensor value with a digital communication method using consecutive frames. In the communication apparatus, a data source unit is configured to generate a frame using a data of a sensor value processed by a signal processing unit. A switching unit is configured to perform a signal switching to permit a transmission circuit to perform a re-transmission of re-transmitting a signal including the sensor value stored in a memory in response to a restoration of the power after an instantaneous power interruption. A frame monitoring unit is configured to monitor a status of a frame transmission and determine a frame at the occurrence of the instantaneous power interruption. The sensor value to be re-transmitted is determined based on information of the frame determined by the frame monitoring unit at the occurrence of the instantaneous power interruption.

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 position detector includes a Hall element that detects a magnetic flux density and a temperature detection element that detects the temperature of the Hall element. In a rotation angle calculation process, a temperature correction value a is calculated by substituting a detection temperature t of the temperature detection element and a reference maximum voltage V0 at a reference temperature t0 for a=V0×k (t−t0). Next, a correction maximum voltage Vt is calculated by substituting the temperature correction value a for a temperature characteristic formula of Vt=V0+a. Further, a rotation angle θ of a magnet relative to the Hall element is calculated by substituting an output voltage VH of the Hall element and the correction maximum voltage Vt for θ=sin−1 (VH/Vt). Since the correction maximum voltage Vt is corrected according to the temperature, the rotation angle is accurately detected.
