Abstract: A cutout portion is formed in a substrate of a magnetic detection device, the cutout portion opening at an outer edge of the substrate. Magnetic detection elements of a magnetic sensor detects magnetic field formed by first and second collector portions. A mold section encapsulates the magnetic detection elements. The magnetic sensor is surface mounted such that a portion of the mold section overlaps with the cutout portion. The first collector portion faces a front surface of the magnetic sensor. A portion of the second collector portion is positioned in the cutout portion to face a rear surface of the magnetic sensor. Accordingly, compared to a case where a cutout portion is not provided, a magnetic circuit gap between the first and second collector portions is reduced.

Abstract: A torque sensor includes: a torsion bar coaxially connecting a first shaft and a second shaft; a multipole magnet; a pair of magnetic yokes; and a magnetic sensor capable of detecting a density of magnetic flux formed by the pair of the magnetic yokes and having an inner magnetosensitive surface facing inward in a radial direction and an outer magnetosensitive surface facing outward in the radial direction when viewed along a central axis of the torsion bar. The torque sensor includes: a magnetic flux guiding member capable of magnetically coupling the magnetic yoke and the outer magnetosensitive surface of the magnetic sensor; and a water blocking portion capable of housing the magnetic sensor and the magnetic flux guiding member to restrict the magnetic sensor from coming into contact with water.

Abstract: Claw portions opposing a magnet are disposed on inner edges of a first yoke and a second yoke. Wall portions are disposed on outer edges of the first yoke and the second yoke so as to extend in an axial direction. A distal end of the wall portion and another distal end of the other wall portion are spaced apart from each other in the axial direction and disposed to oppose each other. A magnetic sensor is disposed between the distal ends in the axial direction. End faces oblique to the axial direction are disposed on the distal ends and a distance between the distal ends on a radially inner side is made shorter than a distance between the distal ends on a radially outer side.

Abstract: A torque detecting apparatus includes a first shaft; a second shaft; an elastic member coaxially linking the first and second shafts; and a magnet attached to the first shaft; a pair of magnetic yokes composed of a first magnetic yoke and a second magnetic yoke, the first and second magnetic yokes being fixedly installed on the second shaft; and a magnetic sensor. Each magnetic yoke includes an opposing portion and a wall portion. The opposing portion is opposed to the magnet and displaced circumferentially relatively to the magnet when the elastic member is subjected to a torsional displacement.The wall portions of the first and second magnetic yokes are separated and positioned outside the opposing portions in the radial direction. The wall portions of the first and second magnetic yokes extend to be mutually opposed. The magnetic sensor is positioned between the wall portions.

Abstract: A hole is formed in a substrate of a magnetic detection device, the hole being spaced away from an outer edge of the substrate. Magnetic detection elements of a magnetic sensor detects magnetic field formed at first and second collector portions. A mold section encapsulates the magnetic detection elements. The magnetic sensor is surface mounted such that a portion of the mold section overlaps with the hole. The first collector portion faces a front surface of the magnetic sensor. A portion of the second collector portion is positioned in the hole to face a rear surface of the magnetic sensor. Accordingly, compared to a case where a hole is not provided, a magnetic circuit gap between the first and second collector portions is reduced.

Abstract: A torque sensor includes: a torsion bar; a multi-pole magnet; a pair of yokes on an outside of the multi-pole magnet in a radial direction and providing a magnetic circuit in a magnetic field generated by the multi-pole magnet; and a pair of magnetic sensors arranged along a circumferential direction. Each magnetic sensor includes a magnetism sensing part for detecting a magnetic flux density generated in the magnetic circuit, and outputs a detection signal to an external computing device. The magnetic sensors output the detection signals to the external computing device such that the computing device calculates a sum of outputs or a difference of outputs of the magnetic sensors so as to cancel a variation of the outputs produced by a magnetic flux generated from the multi-pole magnet and directly reaching the magnetism sensing parts.

Abstract: A torque sensor has a magnetic sensor, which is composed of a first magnetic detecting element, a second magnetic detecting element and a comparator. The first magnetic detecting element outputs an output signal of a provisional detection value, while the second magnetic detecting element outputs an output signal of a reference value. The comparator compares the provisional detection value and the reference value and outputs the provisional detection value as an authorized detection value, when a difference value between the provisional detection value and the reference value is smaller than a predetermined threshold value.

Abstract: A magnetic detection module is provided so as to be selectively mountable in any of housings having a plurality of specifications having different shapes or sizes of mounting portions, and detects magnetic flux generated in the housing. The magnetic detection module includes one or more magnetic sensors that detect magnetic flux, a case in which the magnetic sensors are housed, and a cap that can be attached to an end of the case and is provided with a sealing member. The magnetic detection module can be attached to the housing of the first specification with the cap not attached to the case, and can be attached to the housing of the second specification through a sealing member with the cap attached to the case.

Abstract: A torsion bar of a torque detection device converts torque applied between an input shaft and an output shaft to a torsional displacement. A pair of yokes is secured to the output shaft, and forms a magnetic circuit in a magnetic field of a multipolar magnet secured to the input shaft. A magnetic flux guide member has a main body facing the yoke to guide magnetic flux of the magnetic circuit. A magnetic sensor is placed at an extension, and detects magnetic flux guided by the magnetic flux guide member. The magnetic flux guide member is configured to allow magnetic permeance per unit area between the magnetic flux guide member and the yoke to be greater at a location in the main body from which the extension is branched, than at a circumferential end portion of the main body.
