摘要： PROBLEM TO BE SOLVED: To improve the linear displacement detecting accuracy for a control shaft 11 of a variable valve train 6 of an internal combustion engine (an in-line 4-cylinder engine).
SOLUTION: A bearing 12 for releasing rocking of the control shaft 11 is installed between a sensor rod 13 and the control shaft 11 of the variable valve train 6. Thus, torsion of a sensor lever 14 rotating round the shaft center of the sensor rotor 15 is eliminated so that a linear displacement measuring error for the control shaft 11 can be reduced. Further, a linear rotation displacement converting mechanism for converting linear displacement of the control shaft 11 to rotational displacement is divided into a sensor rod 13 and a sensor lever 14. Thus, distortion caused in converting the linear displacement of the control shaft 11 to the rotational displacement of the sensor lever 14 and the sensor rotor 15 can be absorbed so that the linear displacement detecting accuracy for the control shaft 11 can be improved.

摘要： PROBLEM TO BE SOLVED: To reduce stress applied to connection parts between wiring materials and an electric component thereby maintaining the connection between the wiring materials and the electric component even if an insulation material is subject to temperature load fluctuations to expand or contract in a wiring device where the wiring materials are connected to the electric component by bridging.SOLUTION: An electric component 3 is supported through a column part 4 composed of at least one of an insulation material 1 and a wiring material 2. In this structure, the column part 4 deflects when heat expansion or heat contraction occurs in the insulation material 1 thereby reducing the stress applied to connection parts between the wiring materials 2 and the electric component 3. Thus, this structure prevents the damage to the connection parts between the wiring materials 2 and the electric component 3 even if the insulation material 1 is repeatedly subject to temperature load fluctuations over a long period. Further, since the electric component 3 is supported by an upper part of the column part 4, a space α is formed between the insulation material 1 and the electric component 3. Hence, the space α prevents a failure that solder 5 melted during joining causes short circuits in the two wiring materials 2 due to capillary phenomenon.

摘要： PROBLEM TO BE SOLVED: To provide a temperature characteristic correcting method of a rotation angle detector for accurately correcting the temperature characteristic of a Hall element, and to provide the rotation angle detector.
SOLUTION: The rotation angle detector 10 detects the rotation angle of a detected object. A rotor core 12 and a permanent magnet 14 rotate with the detected object. A Hall IC 30 detects magnetic flux density varied by rotation of the rotor core 12 and permanent magnet 14, and outputs it as voltage. The Hall element mounted in the Hall IC 30 has a temperature characteristic where the offset voltage and sensitivity vary with temperature. A temperature characteristic correction value for correcting the temperature characteristic of the Hall element is set according to the magnetic flux density in the detection range of the Hall element, thereby accurately correcting the temperature characteristic of the Hall element regardless of the magnetic flux density.

摘要： PROBLEM TO BE SOLVED: To prevent the degradation of detection precision accompanying displacement of a rotor 3 in a rotating angle detector 1 for composing part of a magnetic circuit by the rotor 3 integrally rotated with a rotating shaft 2 and detecting a magnetic flux changed in response to a rotating angle of the rotating shaft 2.
SOLUTION: The rotating angle detector fixes first and second stators 5, 6 on both the sides of an axial direction of the rotor 3, and forms first and second axial air gaps a1, a2 between the rotor 3 and the first and second stators 5, 6. In addition, the rotating angle detector includes an axial protrusion 13 opposite to a radial direction to the stator 5 by being projected to one direction side of an axial direction on the outer peripheral side of the first stator 5 on the rotor 3 and forms a radial air gap b between the axial protrusion 13 and the first stator 5. Thereby the rotating angle detector prevents the degradation of detection precision by hardly generating large variation for detection precision of the rotor 3 even when the rotor 3 displaces in any one direction of an axial or radial direction.

摘要： PROBLEM TO BE SOLVED: To provide a valve device for suppressing the impairment of the symmetry of a magnetic field as a result that magnets 21A, 21B held at an inner peripheral edge 20 are pulled to the inner peripheral edge 20 with the thermal expansion of a resin rotor 15 mounted at one end of a valve shaft 3. SOLUTION: The magnets 21A, 21B are arranged so that an axial center flux perpendicular line 32 being perpendicular to the direction of a magnetic flux formed on an axial center 31 of the valve shaft 3 and passing through the axial center 31 is oriented to the middle of a gear setting range 33. Thus, the direction of strongly operating tensile force with thermal expansion corresponds to the direction of the axial center flux perpendicular line 32. The magnetic field is therefore moved in parallel to the direction of strongly operating the tensile force while minimizing damage to its symmetry. Even when the magnets 21A, 21B are pulled to the inner peripheral edge 20, the impairment of the symmetry of the magnetic field is suppressed. COPYRIGHT: (C)2009,JPO&INPIT
