摘要： A position sensor includes a longitudinally extending permanent magnet member at least two longitudinally extending arc-shaped projecting elements respectively projecting from the opposite ends toward the inside space to confront each other at a distance and a pair of compatible main magnetic sensors disposed in the inside space along the longitudinal axis at an interval so as to generate a pair of output signals when the permanent magnet member shifts along the longitudinal axis. The opposite ends of the permanent magnet member are configured to surround a common inside space and polarized to have opposite magnetic poles so as to provide in the inside space a magnetic field whose magnetic flux density becomes a maximum at a longitudinal center of the inside space and gradually becomes smaller as a position of the inside space shifts from the longitudinal center along a longitudinal axis of the permanent magnet members. The arc-shaped projecting elements are arranged so that the magnetic flux density and each of the output signals can be expressed by a cosine of a shift value from the longitudinal center, and the interval is ¼ of the cycle of the cosine.

摘要： PROBLEM TO BE SOLVED: To prevent contaminated air from entering a vehicle if outside air is contaminated by reducing an outside-air side holding time during which an inside-to-outside air switching damper is held on the outside air suction side. SOLUTION: If the degree of contamination of outside air is high, a controller switches an inside-to-outside air switching damper to the inside air suction side for a fixed time t0 , then determines the degree of contamination of air inside the vehicle, and determines heater temperature H and an outside air side holding time T; it then raises the heater temperature from normal temperature, e.g. 400 deg.C, holds the damper for a predetermine time t1 then holds the damper on the outside air side for a holding time T3 seconds before the end of the predetermined time t1 and, if the predetermined time t1 has ended during this holding time, resets the heater temperature to normal temperature, e.g. 400 deg.C, and returns to determining action whereby it determines the degree of contamination of outside air.

摘要： PROBLEM TO BE SOLVED: To obtain a position detection sensor 1 with high detection accuracy even when electric signals output from a magnetic field formed from magnets 2, 3 as a movable element, and magnetic field detection means 4, 5 as a stator vary with temperatures. SOLUTION: The position detection sensor 1 has swelling portions 6, 7 swelling in an arc shape in a lateral direction, the two magnets 2, 3 displacing in a longitudinal direction, and the two magnetic field detection means 4, 5 that detect the magnetic field formed from the magnets 2, 3. Both of the magnets 2, 3 are polarized in the longitudinal direction, and one edge side forms an S pole, and the other side forms an N pole. Besides, the magnetic field detection means 4, 5 are disposed at a predetermined clearance in the longitudinal direction. The clearance is one seconds of a cycle d of a trigonometric function if correlation characteristics between the coordinate in the longitudinal direction and flux density of the magnetic field formed at an air gap is taken as the trigonometric function. Thus, the position detection sensor 1 with high detection accuracy is obtained irrespective of temperatures. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To absorb the rattling by a spline between an output shaft and a manual shaft while suppressing an increase in the axial physical size of a rotary actuator, and to prevent the mounting property deterioration of the rotary actuator due to the influences of a shift position sensor.
SOLUTION: A shift range switching device for eliminating the rattling by the spline comprises a first gear 81 provided on the output shaft 17, a second gear 82 engaging with the first gear 81 and supported by a second shaft 83 on the radial outside of the output shaft 17, and a torsion coil spring α for energizing the second gear 82 in one rotating direction. A rotary member 85 and a fixed member 86 form a non-contact rotating angle sensor which detects the set position of a shift range from the rotating angle of the rotary member 85. An output shaft rotation energizing means 80 which functions as the shift position sensor β is provided on the radial outside of the output shaft 17 for avoiding the mounting property deterioration of the rotary actuator 1 without increasing the axial physical size of the rotary actuator 1.

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 provide a knock sensor capable of preventing intrusion of water into a sensor part and securing insulation between the sensor part and pressure holding means for a long period of time.SOLUTION: An activation treatment (plasma treatment, UV treatment, etc.) is applied to an insulating plate 3 before being assembled into a knock sensor and thereafter a mold resin 4 is molded to enhance a binding power between the insulating plate 3 and the mold resin 4. As a result, the knock sensor is used for a long period of time, and even if a clearance is formed due to exfoliation of the mold resin 4 from an outside of the knock sensor to a vicinity of the insulating plate 3 caused by stress or the like by any chance, the exfoliation of the mold resin 4 from the insulating plate 3 is prevented by enhancing the binding power by the activation treatment, so that water can be prevented from reaching a sensor part 1. Thereby, insulation between the sensor part 1 and pressure holding means 2 can be secured for a long period of time and reliability of the knock sensor can be improved.

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.
