摘要： PROBLEM TO BE SOLVED: To heighten linearity of a magnetic flux density to a rotational angle in a rotational angle detection device having a widened detection angle range with the aim of controlling low the magnetic flux density in a prescribed rotational angle.
SOLUTION: An external magnetic body 11 for sending a part of a magnetic flux generated from a magnet 5 when the rotational angle of a rotor 1 is near 70° is provided on a fixing member on the circumference of the rotor 1. Hereby, the magnetic flux passing through a Hall IC 7 can be reduced when the rotational angle is around 70°, and a changing characteristic of the magnetic flux can be linearized. Namely, while keeping a detection rotational range wide, the changing characteristic of the magnetic flux density passing through the Hall IC 7 can be approximately linearized.

摘要： PROBLEM TO BE SOLVED: To provide an angle-of-rotation detector for which the output characteristic of a magnetism detecting element with respect to the angle of rotation of an object to be detected can be set within the range of >=180 deg. and which can be improved in angle-of-rotation detecting characteristic. SOLUTION: This angle-of-rotation detector is provided with a rotor constituted of two magnets 1 and a main yoke 2 and a stator constituted of one set of auxiliary yokes 3 and the magnetism detecting element 4 and the rotor is fixed to the rotating shaft of an object to be detected. The main yoke 2 constitutes a magnetic circuit by closing the space between the magnets 1 in a ring-like state. The auxiliary yokes 3 are arranged with a gap 5 in between and the magnetism detecting element 4 is incorporated in the central part of the gap 5. The stator is positioned in the rotor so that the air gap G formed between the stator and rotor may gradually change in the peripheraly. To be concrete, the direction of the gap of the stator is made coincide with that of the center line A-A of the rotor and the center Os of the stator is shifted from the center Or of the rotor by a prescribed amount L.

摘要： PROBLEM TO BE SOLVED: To solve a problem of being incapable of detecting 90° or more by setting a magnetic flux density around a throttle valve of 0° where the detection precision is required most to the magnetic flux density of 0, in a magnet having characteristics that a magnetic flux density is changed according to a temperature, the change in temperature characteristics is minimized when the magnetic flux is 0, and a magnetism detection precision around the magnetic flux density of 0 is high.
SOLUTION: A supportive magnet 8 offsetting the magnetic flux density provided from main magnets 4 to Hall ICs 6 by applying a prescribed magnetic flux density to the Hall ICs 6 is fixedly disposed between the two Hall ICs 6. This constitution can change the angle in which the magnetic flux density becomes 0 by the supportive magnet 8. Therefore, while an angle 0° position where the detection precision is required most is set to the magnetic flux density of 0, the detectable range of the rotation angle can be extended to be more than 90°.

Accordingly, arranged positions for configuration elements of the Hall ICs 31, 32, stator core 34, and lead frame 33 can precisely be ensured in the resin mold component (sensor cover) 7 with small light weight and low cost. Thus, the deviations in position relation between the permanent magnet 6 that is arranged at the side of a shaft 3 of the throttle valve 2 and the integrated Hall ICs 31, 32 at the side of the sensor cover 7 can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a rotational angle detector capable of preventing operation failure of a Hall IC by discharging electric charge charged on a stator 15.
SOLUTION: A metallic terminal 16 for electrically connecting the stator 15 to an intermediate shaft 11 is built in a sensor cover 6. The metallic terminal 16 is inserted into the sensor cover 6 in a condition that one end of the metallic terminal 16 is in contact with a surface of the stator 15. The other end of the metallic terminal 16 is exposed to a recessed section 6a formed on the sensor cover 6 and is electrically connected to the intermediate shaft 11 fitted to the recessed section 6a. With the above configuration, when static electricity is applied to the stators 15, the static electricity can be discharged from the stator 15 to a throttle body via the metallic terminal 16 and the intermediate shaft 11. As a result, electric charge is not charged to a face of a circuit of the Hall IC having a Hall element mounted thereon, thereby preventing operation failure of the Hall IC.

摘要： PROBLEM TO BE SOLVED: To inhibit an insert member 2 from lifting even without performing the press-fit of the insert member 2 to a locating pin 11 at the time of injection molding, regarding a resin molded product having the plate-like insert member 2 built therein.
SOLUTION: In the insert member 2 of the resin molded product, part of an upstream side peripheral edge 9 is tilted downward toward an injection port 7 to form an upstream side tilted part 18. By this, in a mold, a passage for the inflow of resin 3 to the lower side of the insert member 2 is narrowed toward the injection port 7 and a passage for the inflow of the resin 3 to the upper side of the insert member 2 is widened toward the injection port 7. As a result, the injected resin 3 hardly flows into the lower side of the insert member 2 and easily flows into the upper side of the member 2. It is possible, therefore, to inhibit the insert member 2 from lifting even if the insert member 2 is not press-fitted to the locating pin 11 upon the injection molding.

摘要： PROBLEM TO BE SOLVED: To provide a throttle valve device for restraining an output variation in an angle sensor by noise of an electric motor, without increasing a physical constitution, and without increasing cost.
SOLUTION: This throttle valve device 1 has a DC motor 13 and the angle sensor 15. Power is supplied to the angle sensor 15 via positive electrode and negative electrode power wiring patterns 162a and 162b of a wiring part 162 composed of a flexible printed wiring board stuck to a cover 16. The positive electrode and negative electrode power wiring patterns 162a and 162b are separated by a predetermined distance from positive electrode and negative electrode power terminals 161a and 161b supplying the power to the DC motor 13, and are mutually arranged in parallel at a predetermined interval. Thus, a source voltage variation in the angle sensor 15 is restrained without arranging a filter, and an output variation in the angle sensor 15 by noise of the DC motor 13 is restrained without increasing the physical constitution, and without increasing the cost.

摘要： PROBLEM TO BE SOLVED: To provide a lead frame capable of mounting no outer lead not to be used, but capable of making only outer leads to be used neighbor it. SOLUTION: When four outer leads 4 are used, an X4 part is cut, and when six outer leads 4 are used, an X6 part is cut. This removes the unused outer leads when the four outer leads 4 are used, and a 4P type lead frame with the adjacent four outer leads 4 is manufactured. When the six outer leads 4 are used, a 6P type lead frame with the adjacent six outer leads 4 is manufactured. This moves the 4P type lead frame and the 6P type lead frame to a common architecture to lower the cost of the lead frame. The 4P type external connector can be used for the 4P type lead frame.

摘要： PROBLEM TO BE SOLVED: To provide a small rotation angle detector for detecting the rotation angle of a detecting object without increasing the number of magnetic flux density detecting elements, while preventing the inteference of relative rotations of a magnet and a magnetic flux density detecting element. SOLUTION: A yoke 12 covers the circumference of a magnet 20 and a Hall IC 30. The magnet 20 is a permanent magnet, which rotates with the detecting object and set at a position radially shifted from the rotating center 100 of the detecting object. The magnet 20 is magnetized along the tangential direction of the rotating circle of the detecting object. The Hall IC 30 is set at a position, radially shifted from the rotating center 100 toward the circumferential side of the rotating track 110 of the magnet 20 so that it cannot prevent the rotation of the magnet 20. The detection surface 32 of the Hall IC 30 is laid along the rotating circle of the detecting object. COPYRIGHT: (C)2007,JPO&INPIT
