Abstract: A blower configured to circulate cold air inside a body of a refrigerator. The blower includes a casing, an impeller accommodated in the casing, and a support member configured to support the impeller against the casing. The impeller includes a disk-shaped base plate rotatably supported by the support member. The casing includes an inner circumferential surface extending so as to gradually move away from an outer circumference of the base plate toward a rotational direction of the impeller at a predetermined position around the outer circumference of the base plate, and a first case flow path between the inner circumferential surface and the outer circumference. An introduction port configured to introduce the cold air to a second case flow path branched from the first case flow path is formed on the inner circumferential surface of the casing.

Abstract: A magnetic field calibration device is used to calibrate a magnetism measurement device having a plurality of magnetic sensors and includes a first holder having a first holding surface, a second holder having a second holding surface having a fixed relative positional relation with the first holding surface, and magnetism generating parts fixed to the first holding surface and the second holding surface. Thus, calibration can be completed with a single operation by assigning the first and second holding surfaces of the magnetic field calibration device respectively to the first and second measurement surfaces of the magnetism measurement device. In addition, since the relative positional relation between the first and second holding surfaces is fixed, measurement results obtained from the individual measurement surfaces match each other.

Abstract: A magnetic sensor array includes a plurality of magnetic sensors. The magnetic sensor includes a sensor housing body housing the sensor chip and first and second connection parts formed on the sensor housing body. The first connection part formed on one of adjacent magnetic sensors and the second connection part formed on the other one thereof are axially supported on each other to achieve mutual connection between the plurality of magnetic sensors. Thus, it is possible to vary the relative angle between two adjacent magnetic sensors with the first and second connection parts as an axis. This allows the plurality of magnetic sensors to be pressed perpendicularly against even a curved surface of an object to be measured, and the pressed state can be easily maintained.

Abstract: A magnetically shielded room reducing pressure felt by a person inside includes an upper shielding body, a side periphery shielding body, and a lower shielding body, all of which define a magnetically shielded inner space. A magnifying lens is located in the upper shielding body. The magnifying lens can magnify and project an incident image from outside to a range of one inner side surface of the magnetically shielded room. so that the range should be 50% or more of the area of the one inner side surface. The range includes most of the area above a line of sight of a person in the magnetically shielded room. The magnifying lens is provided at a position closer to the one inner side surface as a projection target of the lens than the other inner side surface as a non-projection target facing the one inner side surface as the projection target.
