Abstract: An electromagnetic valve has a solenoid, which includes a coil, a plunger, a fixed core, and a plunger spring. The fixed core is E-shaped and has a base, a first outer leg, a second outer leg, and a central leg. The first outer leg, the second outer leg, and the central leg extend from the base. The first outer leg has a first outer attraction surface configured to attract the plunger. The second outer leg has a second outer attraction surface configured to attract the plunger. The central leg has a central attraction surface configured to attract the plunger. The central attraction surface is larger in area than each of the first and second outer attraction surfaces.

Abstract: An inspection device includes: an illumination device that irradiates an object with near infrared light; a spectroscope that disperses reflected light from the object irradiated with the near infrared light; an imaging device that takes a spectroscopic image of the reflected light dispersed by the spectroscope; and a processor. The processor: obtains spectral data at a plurality of points on the object based on the spectroscopic image obtained by the imaging device; selects, as typical spectral data representing the object from among the spectral data at the plurality of points, one of: spectral data in which a luminance value in a predetermined wavelength is a median value; and spectral data in which a summation of luminance values in a predetermined wavelength range is a median value; and performs a predetermined analysis for the object based on the typical spectral data and detects a different type of object.
