摘要： The excitation coils 13c and 13d and the detection coil 12 are discretely disposed. The displacement sensors 10a to 10d, which are respectively constituted in such a manner that the detection is performed on the basis of the balance between the excitation coils 13c and 13d to obtain the remaining variation with satisfactory linearity and high sensitivity in which the impedance due to the DC resistance component or the like is cancelled and removed while using the small sized core body 11, are arranged so as to interpose the object 14 to be detected such as the rotary shaft between them. Therefore, the stable detecting operation can be realized with an inexpensive circuit regardless of the variation of the environmental temperature without using the conventional constant current circuit. The stable detection result can be obtained with the simple structure and the satisfactory detection sensitivity.

摘要： Ramp arrangements and methods in accordance with the present invention can provide the position or velocity of an actuator assembly in a rotating media data storage device while loading or unloading a head connected with the actuator assembly from a disk. One such arrangement comprises a conductive ramp electrically coupled to a conductive suspension lift tab such that a closed circuit is formed when the head is unloaded from the disk. As the suspension lift tab slides along the ramp, the resistance of the circuit changes. By measuring multiple positions at multiple times, a head velocity can be determined. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

摘要： Non-contact type Hall ICs detecting an rotation angle of a throttle valve, a stator core strengthening a magnetic field around the Hall ICs, a lead frame connecting the Hall ICs to an outside ECU are integrated in a sensor cover by resin molding. Thus, the Hall ICs, the stator core, and the lead frame are accurately positioned in the sensor cover. As a result, the Hall ICs are accurately positioned with respect to a permanent magnet disposed in a shaft side of the throttle valve, thereby improving an accuracy of detecting the rotation angle of the throttle valve.

摘要： A through the hole rotary position sensor which incorporates a single ring magnet with a central aperture is disclosed. The rotating shaft whose angular position is to be sensed is adapted to be received in the central aperture. The through the hole rotary position sensor in accordance with the present invention also includes a pair of pole pieces which extend at least partially around the circular magnet. One or more magnetic flux responsive elements are disposed adjacent the pole pieces. In order to shield the sensor from undesirable magnetic flux influences through the rotatable shaft, an optional internal shunt ring may be provided around the exterior of the rotatable shaft. In order to shield the sensor from undesirable external magnetic flux influences, an optional external shunt ring and top and bottom shunt discs may also be provided. The circular magnet, pole pieces, magnetic flux responsive element, optional shunt rings and shunt discs are carried by a non-magnetic housing. By utilizing a simple circular or ring magnet, the cost and complexity of the sensor is relatively lower relative to other known sensors.

摘要： Magnetic sensor methods and systems for decreasing variations in switching angles thereof are disclosed. An angled face magnet can be angularly positioned adjacent one or more sensing elements of a magnetic sensor thereof. The angled face magnet can be configured to include a recessed portion into which the one or more of the sensing elements can be positioned. When the teeth of a target pass by the angled face magnet, it produces a magnetic signal, which is steeper in switching regions. The angle face magnet can thus alter a magnetic signal thereof, thereby decreasing variations in switching angles associated the magnetic sensors relative to a sensor target.

摘要： A variable reluctance resolver is provided with an output winding having a reduced effect from externally introduced leakage magnetic flux. A variable reluctance resolver is provided with a resolver excitation winding and a resolver output winding wrapped around multiple stator magnetic poles which respectively output rotary angle X and Y components as a rotor turns. Windings are wound such that the polarities of output voltages on output windings wound around a row of three or more stator magnetic poles will be the same; all of the output windings are divided into an even number, two or greater, of groups, and output windings are serially connected in such a way that adjacent group output voltage polarities mutually differ. Also, the number of turns inside the aforementioned groups is wound so that the number of turns of output windings positioned on each of the adjacent group sides is smaller than the number of turns of the output windings positioned on the inside of the aforementioned output windings in the relevant group.
