Abstract: A three-dimensional printing apparatus includes a projector to project a first image onto a tank and a controller to control the projector. The controller includes an acquirer, an inclination calculator, a vertical and horizontal correction value calculator, a memory, and a corrector. The acquirer projectively transforms the first image, thus acquiring a second image obtained by correction of the first image. The second image includes a projection sub-image. The inclination calculator calculates horizontal and vertical inclinations of the projection sub-image in the second image. The vertical and horizontal correction value calculator calculates a first correction value based on the horizontal inclination, and calculates a second correction value based on the vertical inclination. The memory stores a third correction value. The corrector corrects the brightness distribution of the second image using a fourth correction value calculated based on the first to third correction values.

Abstract: Provided is a gas sensor having excellent detection sensitivity and responsiveness. In a sensor element, 3.5?D2/D1?6 is satisfied, where D1 is a value of a diffusion resistance of a measurement gas via a main gas distribution part extending from an outside edge position of a first gas inlet to the second internal space, and D2 is a value of a diffusion resistance of a measurement gas flowing via a second gas inlet that causes the outside and the second internal space to communicate with each other. The concentration of a predetermined gas component contained in the measurement gas through the second gas inlet is determined on the basis of a potential difference between the sensing electrode and a reference electrode, while pumping oxygen in or out for the measurement gas via the main gas distribution part such that the oxygen concentration of the second internal space is maintained at 1 vol % or more.
