Abstract: To provide an apparatus for monitoring a fluid flow rate, which is capable of performing monitoring without a data deficit, and displays information on a trend of a past history. A monitoring apparatus accepts, from the flow meter, integrated flow amount data for every day-and-time section, and a current flow rate, and graphically displays, on the basis of the integrated flow amount data for every day-and-time section, an integrated flow amount corresponding to each day-and-time section, on the basis of the integrated flow amount data for every day-and-time section including the current day-and-time and for every another plurality of continuous day-and-time sections.

Abstract: High processing accuracy of a workpiece is maintained even if the workpiece is misaligned. A laser processing apparatus includes: a setting section that sets a pattern area and a distance measurement position on a captured image; a condition setting storage section that stores image information in the pattern area; a position correction section that detects a misalignment of a new workpiece different from a workpiece used to set the pattern area and corrects the distance measurement position on the new workpiece; a distance measurement section that measures a distance based on a light reception position of distance measuring light in a distance measuring light receiving section; and a Z scanner that adjusts a focal position based on a measurement result of the distance measurement section prior to irradiation of the workpiece with laser light.

Abstract: Provided is a flow meter capable of logging data more reliably. In this operation, a detection element repeatedly detects a physical quantity related to a flow rate of a fluid flowing in a pipe in a predetermined sampling cycle. Based on physical quantities, a calculation part sequentially calculates the flow rate of the fluid in the pipe. Further, a time measurement part calculates the time. A control storage part is caused to store a logging target, a logging cycle, and logging start definition information. Based on the logging start definition information, a control part automatically starts logging of the logging target in response to startup of the flow meter, and causes a log storage part to store the time measured by the time measurement part and a numerical value of the logging target in association with each other in every logging cycle.

Abstract: Recording a history related to an operation of a safety program contributes to a determination of a cause of a false OFF signal. A safety controller acquires, from at least one safety input device or safety sensor, extra information that is not used for obtaining an output signal and records an input signal and an output signal together with the extra information as history information at predetermined recording intervals.

Abstract: To provide a sensor unit that simultaneously displays other information together with a threshold and a physical quantity. A sensor unit causes a dot-matrix display unit to display a threshold and a physical quantity in a first display form and causes the dot-matrix display unit to display, together with the physical quantity and the threshold, additional information (e.g., a power mode) different from the physical quantity and different from the threshold in a second display form. The area of a third display region 303 for the threshold in the second display form is smaller than the area of a second display region 302 for the threshold in the first display form. The area of a fourth display region 304 for the information in the second display form is obtained by reducing the area of the second display region 302.

Abstract: A handheld optical information reading device is provided which comprises a housing, a grip arranged on the housing, an image capture device, an illuminator, an illumination controller, an imaging controller, an image processor, and a reader. The image capture device captures an image including a symbol. The illuminator includes lighting devices around the periphery of an optical axis of the image capture device. The illumination controller controls the illuminator to selectively successively light up the lighting devices based on a predetermined order whereby irradiating a symbol with light in different illumination directions with respect to the optical axis. The imaging controller controls the image capture device to capture images of the symbol every when the lighting devices are selectively successively lighted up. The image processor creates an outline image of the symbol based on the captured images. The reader reads the symbol based on the created outline image.
