Abstract: A valve device includes a cover and a valve. The cover is attached to be fixed to a mating part to which the cover is attached, and includes a cover top part and a leg part extending from an outer peripheral part of the cover top part toward a mating part side to be attached to the mating part at a distal end part in an extending direction, the leg part is one of a plurality of the leg parts that are intermittently disposed in a circumferential direction, and a release hole allowing a release of a fluid from an inside to an outside of the cover is disposed in each space between the leg parts that are adjacent to each other in the circumferential direction.

Abstract: A programming device creating a program in FBD language describing processes by connecting FBD parts on an editor screen, includes: a part information managing unit managing size information indicating a size of an FBD part; a recommended order determining unit acquiring, when operation to newly arrange an FBD part relative to an already-arranged FBD part on the editor screen is performed, size information on the already-arranged FBD part and size information on the FBD part to be newly arranged, from the part information managing unit, detecting regions where the FBD part to be newly arranged can be arranged based on the acquired size information, and determining a recommended priority order of part arrangement among the regions based on positions of the detected regions; and an editor unit displaying the recommended priority order determined by the recommended order determining unit in the regions.
