Abstract: A three-dimensional measurement device includes: an optical system that splits incident light into two lights, radiates one of the two lights as measurement light to a measured object and the other of the two lights as reference light to a reference surface, and recombines the two lights into combined light to emit the combined light; a light emitter that emits predetermined light entering the predetermined optical system; an imaging system that takes an image of output light emitted from the optical system; and an image processor that performs three-dimensional measurement of a predetermined measurement area of the measured object based on an interference fringe image obtained by the imaging system. The image processor obtains intensity image data at a predetermined position along an optical axis direction at each coordinate position in the measurement area by reconstruction based on an interference fringe image of the measurement area.

Abstract: A combination valve includes a valve seat, a diaphragm valve element, a pilot system to automatically bring the diaphragm valve element into or out of contact with the valve seat by use of air pressure, and a manual system to hold the diaphragm valve element in contact with the valve seat even while air pressure is supplied. In the combination valve, a piston rod is provided such that, when the handle is turned to move the manual stem in a seating direction while the diaphragm valve element and the valve seat are separated from each other, the piston rod moves in the seating direction relative to a first piston and a second piston that are pushed by the air pressure in a separating direction.

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.
