Abstract: A quality control system for controlling quality of a paint target includes: an individual identification section associating a step control value and a quality control value with identification information for the paint target on the basis of the amount of movement; a state value computing section calculating a state value indicative of a paint state of the paint target on the basis of a history of a temporal change of the step control value; a learning section learning a correlation between the step control value, the state value, and the quality control value using sets of the step control value, the state value, and the quality control value; an input device receiving information on the amount of movement, the step control value, and the quality control value; and a storage device storing a set of the identification information, the step control value, the state value, and the quality control value.

Abstract: An airflow detection apparatus (1) an airflow detection apparatus (1) that detects an airflow in a painting booth, and includes a thread-like member (2) installed inside the painting booth, an image capture device (4) capable of generating image data obtained by capturing an image of the thread-like member (2), and a calculation device capable of performing calculation processing on the image data. The thread-like member (2) is installed in the painting booth in a mode in which at least a portion thereof is suspended. The calculation device specifies a portion corresponding to the thread-like member (2) in the image data, and detects an airflow based on a position of the portion.

Abstract: A work facility that is capable of adjusting an air volume without a work defect and saving energy. The opening degree of an air volume adjusting damper corresponding to a filter booth for which the individual air volume measured by a corresponding individual flowmeter is the smallest among the respective individual air volumes for the filter booths is adjusted to a completely open state, whereas the opening degree of any other air volume adjusting damper is adjusted to such an opening degree that the individual air volume for the corresponding filter booth as measured by a corresponding individual flowmeter is equal to the smallest individual air volume, and a gas discharge fan is adjusted by a total air volume adjusting mechanism so that a total air volume measured by a total flowmeter is equal to a predetermined target total air volume.

Abstract: The alpha blending calculator of the invention executes an alpha blending calculation in accordance with digital data X, Y, and .alpha.. The alpha blending calculator includes multiplexers which select one of X or Y in accordance with bits of the digital data .alpha., respectively, and a calculating section for shifting outputs of the multiplexers by a predetermined number of bits, respectively, and for calculating a sum of the shifted outputs. The calculating section includes first level to Nth level adding portions, and an adder connected to the outputs of the Nth level adding portion for executing a multi-bit addition. Each of the first level to the Nth level adding portions receives a plurality of stages of data, classifies the plurality of stages of data into quotient groups and a remainder group, calculates a sum and a carry for each of the quotient groups, and outputs the sum, the carry, and the stages of data in the remainder group to the next level adding portion.
