Abstract: A regulator performing fluid control includes an annular protruding portion having a valve seat on its leading end and an annular diameter-decreasing surface formed by decreasing an inner diameter of the annular protruding portion toward a valve hole. The regulator includes a valve element provided with a contact surface to be in contact with the valve seat and a columnar step portion provided on an inner peripheral side of the valve seat protruding from the contact surface toward the valve hole, the step portion having a diameter larger than an inner diameter of the valve hole and being coaxially formed with the valve hole. An annular ridge is formed by an outer peripheral surface of the step portion intersecting an end face of the step portion on the valve-hole side with the annular diameter-decreasing surface to constitute a passage narrowing portion.

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: 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.

Abstract: A vacuum pressure control system that can easily calculate an optimum valve open degree of a vacuum control valve for making a pressure value of a vacuum chamber agree with a target value is provided. A controller approximates a relation between the pressure value in the vacuum chamber and a flow rate of process gas to linear functions, and the system includes a mapping program and a valve-open-degree calculation program stored in the controller to calculate the optimum valve open degree of the vacuum control valve for making the pressure value in the vacuum chamber agree with the target value based on the linear functions when the process gas at the predetermined flow rate is supplied. The valve open degree of the vacuum control valve is adjusted based on the optimum valve open degree so that the pressure value in the vacuum chamber is made agree with the target value.
