Abstract: In a magnetic sensor according to the present disclosure, each of a plurality of magnetoresistance pattern portions includes a first resistance portion and a second resistance portion that are connected together in series. One of two resistance portions connects a first wiring portion and a second wiring portion of a first wiring pattern portion. The other of the two resistance portions connects a first wiring portion and a second wiring portion of a second wiring pattern portion. The two resistance portions are included in the plurality of first resistance portions and the plurality of second resistance portions and located at both ends in a first direction.

Abstract: A magnetic sensor according to the present disclosure includes a supporting substrate, a glazing layer, and a magnetoresistive layer. The glazing layer is formed on the supporting substrate. The magnetoresistive layer is formed on the glazing layer. When viewed in plan in a thickness direction defined for the supporting substrate, an outer edge of the magnetoresistive layer is located inside an outer edge of the supporting substrate.

Abstract: A magnetic sensor according to the present disclosure includes a plurality of magnetoresistance pattern portions that forms a bridge circuit. Each of the plurality of magnetoresistance pattern portions includes a first resistance portion and a second resistance portion that are connected together in series. In each of the plurality of magnetoresistance pattern portions, the first resistance portion and the second resistance portion are spaced from each other in a first direction by a distance that is one half as long as a cycle of magnetization of a detection target. In each of the plurality of magnetoresistance pattern portions, the first resistance portion and the second resistance portion are symmetric to each other with respect to a line when viewed in plan in a third direction.

Abstract: A magnetic sensor according to the present disclosure includes a plurality of magnetoresistance pattern portions that forms a bridge circuit. The plurality of magnetoresistance pattern portions are arranged side by side in a first direction. Each of the plurality of magnetoresistance pattern portions is formed in a second direction perpendicular to the first direction. Each of the plurality of magnetoresistance pattern portions is formed in a meandering shape when viewed in a third direction perpendicular to both the first direction and the second direction. Centroids of the plurality of magnetoresistance pattern portions are located on a centerline of the plurality of magnetoresistance pattern portions in the second direction when viewed in the third direction.

Abstract: A component sensor detects a fluid component with improved accuracy. The component sensor includes tube (3) including tube side (4) that permits inflow of fluid (2), substrate (5) provided to tube (3), first protrusion (6) provided at one end of substrate (5), second protrusion (7) provided at another end of substrate (5), light emitter (9) that emits infrared light (8) toward first protrusion (6), and light receiver (10) that receives infrared light (8). Infrared light (8) entering substrate (5) through first protrusion (6) experiences total reflection inside substrate (5) and exits through second protrusion (7) to head for light receiver (10). Tube side (4) includes two through holes (13) that each extend between an interior and an exterior of tube (3).

Abstract: A sensor includes a body having an internal space allowing fluid to flow into the internal space, a light-emitting device that emits light passing through; first and second light-receiving devices that receive the light that has passed through the internal space, a first optical filter disposed between the first light-receiving device and the light-emitting device and configured to pass the light therethrough, a second optical filter disposed between the second light-receiving device and the light-emitting device and configured to pass the light therethrough, and a controller. The controller is configured to change the light emitted from the light-emitting device, and to compare a ratio between first and second outputs before the change of the light to a ratio between the first and second outputs after the change of the light.

Abstract: A load detecting device has a deformable body, a strain detection element disposed on the deformable body, and an adhesive layer located between the deformable body and the strain detection element and fixing the strain detection element to the deformable body. The adhesive layer is formed of a glass adhesive. The load detecting device has high productivity.

Abstract: A weight sensor includes a deformable body, a first strain resistor provided on an outer side surface of the deformable body, and a pressing member applying a load to the deformable body. The deformable body includes a tubular portion having a tubular shape extending along a center axis and surrounding the center axis, and a projection projecting from an inner surface of the tubular portion. The pressing member moves along the center axis so as to apply a moment to the tubular portion. The resistances of the strain resistors change greatly, allowing the weight sensor to measure a load with high sensitivity.
