Abstract: Provided is a cable disconnection preventing structure or the like in which a conducting wire is not cut at a connecting portion at which a distal end of a conducting wire is connected to a substrate or the like even when a cable is pulled. The cable disconnection preventing structure (100) comprises a case (30) and a conducting wire fixing member (20) which fixes a conducting wire (2) exposed from a sheath (1) to the sheath (1) at one end portion of the cable (10). The conducting wire (2) is disposed between an inner surface (31) around the cable hole (30a) and the conducting wire fixing member (20).

Abstract: A photosensor includes a light projection unit, a light receiving unit, a determination unit that determines a magnitude relation between a received light quantity of the light receiving unit and a threshold value set for the received light quantity; and a threshold value setting unit that sets the threshold value of the received light quantity. The threshold value setting unit calculates for each of a plurality of different wavelength regions, a contrast difference that is a difference between a received light quantity obtained when projection is performed on a detection target on a surface of a workpiece and a received light quantity obtained when projection is performed on a background on the surface of the workpiece, and updates the threshold value based on the contrast difference for a wavelength region among the plurality of wavelength regions in which the contrast difference has a maximum value.

Abstract: This image processing system is provided with: a measurement part which measures the three-dimensional shape of a target object based on a captured image obtained by capturing an image of the target object; a reliability calculation part which calculates, for each area, an index that indicates the reliability in the measurement of the three-dimensional shape; a reliability evaluation part which evaluates, for each area, whether the calculated index satisfies a predetermined criterion; and a display part which simultaneously or selectively displays the measurement result of the three-dimensional shape and a result image that shows the area that does not satisfy the criterion in the captured image.

Abstract: A photoelectric sensor capable of preventing a malfunction caused by mutual interference is provided. The photoelectric sensor includes: a light projecting unit that repetitively emits a set of pulse light, which follows a projected light pattern in which a light projecting period is made different by a fixed time, as signal light; a light receiving element that receives the signal light; and a light receiving controller that distinguishes a light incident state and a light blocked state based on a received light signal from the light receiving element. The light projecting unit has a first pattern having the light projecting period increased by a fixed time and a second pattern having the light projecting period reduced by a fixed time as the projected light pattern, and in the first and second patterns, a pulse indicating a shortest period is included in the light projecting period other than the shortest period.

Abstract: A photoelectric sensor amplifies a received light intensity signal generated through light projection processing and light receiving processing, and performs detection processing using the amplified received light intensity signal. The photoelectric sensor is provided with a variable resistor that generates an adjustment command signal that changes linearly with respect to sensitivity adjustment manipulations performed by a user. Further, the sensor is provided with an amplifier including a variable gain amplifier configured such that the aforementioned adjustment command signal is inputted thereto. Further, the variable gain amplifier is adapted to convert the signal into a gain control signal that changes exponentially with respect to sensitivity adjustment manipulations and, further, is adapted to perform amplification processing using a gain according to the gain control signal.

Abstract: This three-dimensional measurement device includes: a light source, a lens guiding light from the light source to a subject, a photomask disposed on the optical axis between the light source and lens and having a predetermined pattern, a driving device changing the position of one member from the lens and photomask or changing an optical characteristic of the lens, and a control unit controlling the driving device. The control unit fixes an image formation position for light/dark pattern light formed by the photomask at the position of the subject by fixing the position of said member or the optical characteristic of the lens when specifying a first mode, and varies the position of the member or the optical characteristic of the lens to vary the image formation position for the light/dark pattern light such that the light/dark difference caused by the light/dark pattern light is smaller than in the first mode when specifying a second mode.
