  • Inductance-type rotation angle sensor, method of manufacturing the same, and intake control system for engine including the same sensor
    Patent number: 8269484
    Abstract: An inductance-type rotation angle sensor includes: a stator formed by printing an annularly formed magnetic conductor and a receiving conductor placed adjacent to the magnetic conductor on a glass-epoxy-resin substrate; and a rotor having an excitation conductor attached thereto in a manner opposing the magnetic conductor. In the sensor, a thermosetting-resin covering layer, which is connected together through a periphery of the substrate and a through-hole included in this substrate, is formed on both front and back surfaces of the substrate by molding; a portion of the covering layer covering the magnetic conductor and the receiving conductor is formed as a thin thickness part which is thinner in thickness than a remaining portion of the covering layer; and the stator is buried in a thermoplastic-resin control housing with the thin thickness part being exposed to an outside.
