To provide an ion balance sensor and a static elimination system capable of grasping further information regarding an environment of a target space in addition to ion balance in the target space. The ion balance sensor includes a detection plate that is conductive and arranged in a target space. In the ion balance sensor, ion balance in the target space is detected based on a potential of the detection plate. An ion balance signal indicating a detection result is generated. Further, a physical quantity related to an environment of the target space is detected in addition to the ion balance. Another signal indicating information regarding the environment of the target space is generated based on a detection result. The ion balance signal and the other signal are output.

To suppress an error between measurements when a plurality of workpieces having the same shape are measured. A three-dimensional shape data generation apparatus includes: a storage unit that stores a plurality of measurement files in which each of measurement conditions of a workpiece and each of alignment images are associated with each other; a display control unit that causes a display unit to display a live image of the workpiece and an alignment image associated with one measurement file from among the plurality of measurement files stored in the storage unit; a reception unit that receives a measurement start instruction of the workpiece; and a measurement control unit that controls a structured illumination unit and an imaging unit based on the measurement condition associated with the one measurement file in response to the measurement start instruction.

A worker is prevented from being hindered. A safety switch includes a switch body including an electromagnet and an actuator attracted to the electromagnet. The switch body includes a drive control unit and a safety control unit which control the safety switch, and the drive control unit and the safety control unit are surrounded by a housing. The housing is arranged on a back surface side of the electromagnet of the switch body, and the housing forms an accommodating portion that accommodates the drive control unit and the safety control unit.

An image inspection apparatus capable of detecting a fine defect without excessively increasing the resolution of images input to a machine-learned segmentation model. The image inspection apparatus includes an information generation unit that generates defect information based on an annotation specifying a defect region in the training image; a training execution unit that trains a machine learning segmentation model; and an inspection execution unit that executes a trained machine learning model. The training execution unit determines whether to divide the training image according to the detection sensitivity setting of the defect region and, when division is required, the training execution unit divides the training image by a predetermined batch size and inputs the divided training image to the machine learning model.

Internal data contributing to trouble resolving is easily acquired, and usability is improved. An inkjet recording device includes an operating state acquisition unit that acquires parameter values indicating an operating state of the inkjet recording device, which includes at least one a pressurization state, a charge state, a deflection state, and a recovery state, a display unit that displays a reception screen for receiving a command to generate a two-dimensional code from a user, and a code generation unit that generates the two-dimensional code by encoding a parameter value constituting a parameter set of a predefined type among the parameter values acquired by the operating state acquisition unit when the generation command is received via the reception screen of the display unit. The display unit is configured to display the two-dimensional code generated by the code generation unit.

To facilitate installation work of a position detection sensor. A display unit of the position detection sensor includes a plurality of display elements arranged on a housing at positions different from each other along the first direction, and displays a symbol indicating a position of the displacement body along the first direction. The position detection sensor controls the display unit to display in different modes, by displaying the symbol at different positions on the plurality of display elements, a first state in which the displacement body exists at a first position corresponding to one end portion of a displacement range, a second state in which the displacement body exists at a second position corresponding to the other end portion of the displacement range, and an intermediate state in which the displacement body exists at an intermediate position between the first position and the second position.

To facilitate installation work of a position detection sensor. A detection device generates a detection signal according to a position of a magnet provided on a displacement body. A specification unit specifies a position of the displacement body in the first direction on the basis of the detection signal generated by the detection device. A determination unit generates determination information on the basis of the position of the displacement body and detection ranges set in advance. A setting unit is capable of adjusting positions of the first region and the second region set as the detection ranges, and adjusts at least one of the number or a width of the detection ranges.

The present invention allows a user to make trigger settings without editing a robot program and to automatically issue a trigger at optimum timing among the settings. A processor determines, based on timing at which a hand moves out of a capture range of a sensor on a path, timing of issuing a trigger that causes the sensor to capture the next image to dynamically change capture timing of the sensor for each cycle of a picking motion.

Provided is a measurement head and a confocal displacement sensor which are capable of suppressing a decrease in reliability of measurement in a high-temperature environment of the confocal displacement sensor. The measurement head is a measurement head for a confocal displacement sensor having a white light source. The measurement head has a configuration in which a plurality of glass lenses are accommodated in a head metal housing. A metal spring member biases the plurality of glass lenses including the lens toward the +x direction in a state where the lens abuts on the ring screw is provided in the head metal housing. Or a thermal expansion polyimide member provided inside the metal housing.

Favorable measurement workability is obtained by further enhancing a degree of freedom in handling a probe while enhancing measurement accuracy. A probe for a three-dimensional scanner includes a first marker block and a second marker block that are arrayed side by side in a first direction with a scanner unit positioned at a center, and a third marker block and a fourth marker block that are arrayed side by side in a second direction with the scanner unit positioned at the center. The marker blocks have self-luminous markers facing a plurality of directions, respectively. The fourth marker block is arranged to be separated from a plane defined by the first marker block, the second marker block, and the third marker block.
