Abstract: A static electricity visualization apparatus capable of visually identifying a measured level of static electricity is provided. The static electricity visualization apparatus comprises a photographing unit for generating a first photographed image obtained by photographing a measurement target at a first distance from the measurement target in a first mode, and generating a second photographed image obtained by photographing the measurement target at a second distance from the measurement target in a second mode, a static electricity sensor for measuring a static electricity level of the measurement target at the second distance from the measurement target, a processor for matching the second photographed image with the first photographed image, and an output unit for outputting a static electricity visualization image that visualizes a static electricity level measured by the static electricity sensor on the first photographed image, wherein the static electricity visualization image comprises a color corresponding to the static electricity level of the measurement target measured by the static electricity sensor at a position where the second photographed image matches on the first photographed image.

Abstract: A flow rate control apparatus with improved reliability is provided. The flow rate control apparatus comprises a flow rate measuring unit for measuring a flow rate of chemical solution in a chemical solution supply line, a flow rate control unit for comparing a preset target flow rate profile and an applied flow rate profile, and controlling the flow rate of the chemical solution so that the applied flow rate profile matches the target flow rate profile, and a processor for switching the flow rate control unit to a first mode in response to a signal for the flow rate of the chemical solution measured by the flow rate measuring unit being less than a preset level, wherein, in the first mode, the applied flow rate profile includes a profile of a flow rate estimation model simulated using a flow rate of chemical solution measured by the flow rate measuring unit.
