Abstract: Passage forming blocks of a first pilot valve and a second pilot valve each include a supply passage, which opens in a first surface and a second surface and is connected to a valve chamber, a first output passage, which opens in the first surface and are connected to the valve chamber, and a second output passage, which opens in the first surface. Further, the passage forming blocks each include an output passage connecting recess. The output passage connecting recess is provided in a section of the second surface that overlaps with an opening region of the first output passage, which opens in the first surface, and is connected to the second output passage. The first output passage of the first pilot valve is connected to the second output passage of the second pilot valve via the output passage connecting recess of the second pilot valve.

Abstract: An inspection device includes: an irradiator that irradiates an object with near-infrared light; a spectroscope that has a slit where reflected light enters and that disperses the reflected light into wavelength component lights; an imaging device that comprises an imaging element that takes a spectroscopic image of the wavelength component lights; and a processor that: obtains spectral data based on the spectroscopic image; and detects a type of the object using a predetermined analysis based on the spectral data. Each of the wavelength component lights is a single wavelength light, the inspection device satisfies L≥2P, where L is a width of each of the wavelength component lights in a wavelength dispersion direction on a light receiving surface of the imaging element and P is a width of a pixel in the wavelength dispersion direction on the light receiving surface.

Abstract: In this vortex flowmeter provided with a vortex generator and a flow rate measuring unit, a seal member is mounted on a temperature sensing element including a temperature sensor adhered with an adhesive to a metal temperature sensing case. The temperature sensing element is inserted into a first insertion hole formed in a body case so as to communicate with a body passage. A distal end surface of the temperature sensing element is arranged in either a position where the distal end surface is flush with the passage surface of the body passage formed in the body case or a position more outside than the passage surface in the radial direction of the body passage.

Abstract: A three-dimensional measurement apparatus measures measurement targets placed in a target measurement area on a measurement object. The apparatus includes: a measurement module that: is positioned with respect to the target measurement area, and includes: a first irradiator that irradiates the target measurement area with predetermined light for height measurement; a second irradiator that irradiates the target measurement area with predetermined patterned light for three-dimensional measurement; and an imaging device that takes an image of the target measurement area; and a control device that moves the measurement module in a height direction and successively positions the measurement module at a predetermined height position determined by mapping, and performs, based on image data taken by irradiating the target measurement area with predetermined patterned light, three-dimensional measurement to the measurement targets at the predetermined height position.

Abstract: A butterfly valve includes a drive unit and a valve unit that are coupled to each other. The drive unit includes a hollow part in which a rod is inserted between a DD motor and an end portion of the drive unit on a coupling side to the valve unit. In the hollow part, a cylindrical magnetic member is placed coaxially with the rod to cover the outer peripheral surface of the rod. A magnetic fluid is filled in a void between the outer peripheral surface of the magnetic member and the inner peripheral surface of the hollow part. The rod is made of a non-magnetic corrosion-resistant alloy.

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, from among the spectral data at the plurality of points, a group having a highest density of luminance values of a predetermined wavelength component as a dense spectral data group, and performs a predetermined analysis for the object based on the dense spectral data group and detects a different type of object.
