  • Publication number: 20200395822
    Abstract: Provided are a stator and a thermistor unit in which a thermistor can be easily attached while the number of parts is reduced. The stator includes a stator core 2 which is formed in an annular shape and has an attachment hole 21 recessed in the axial direction, a coil 3 which is mounted on the stator core 2 and partly protrudes from an end surface of the stator core 2 in an axial direction thereof, and a thermistor unit 4 which is partly inserted into the attachment hole 21 and fixed to the stator core 2. The thermistor unit 4 includes a thermistor 6 measuring a temperature of the coil 3, and a support body 5 supporting the thermistor 6. The support 5 body has a main body portion 51 holding the thermistor 6 to be in contact with the coil 3, a leg portion 52 which has elasticity, extends from the main body portion 51, and is inserted into the attachment hole 21, and an engagement portion 54 which is provided in the leg portion 52 and engages with the stator core 2.

  • Patent number: 10701341
    Abstract: A calibration method is for a photographic device that photographs an object through a transparent body. The calibration method includes: acquiring a first photographic image by photographing the object without interposing the transparent body; acquiring a second photographic image by photographing the object through the transparent body; calculating an absolute positional deviation that indicates a deviation in coordinates of an image of the object due to the transparent body based on coordinates of an image of the object on the first photographic image and coordinates of an image of the object on the second photographic image; calculating a correction parameter for calibrating the absolute positional deviation; and storing the correction parameter in the photographic device.
