Abstract: A vapor deposition mask made of a semiconductor substrate, comprising a plurality of openings to pass vapor deposition particles, wherein an aperture portion of which opening width is smallest is disposed between an edge of the opening on a vapor deposition source side and an edge of the opening on a substrate side, the opening width on the substrate side is larger than that of the aperture portion, and at least a part of an inner wall of each of the plurality of openings has a uneven shape.

Abstract: A component supply unit set-up system includes a container warehouse configured to store multiple component containers for containing multiple components, a unit storage shed configured to store multiple component supply units used when the component, which is contained in the component container, is supplied in a mounting operation performed by a component mounter, a work table disposed between the container warehouse and the unit storage shed and used for a loading operation of loading the component supply unit with the component container , a container conveyance robot configured to convey the component container between the container warehouse and the work table, and a unit conveyance robot configured to convey the component supply unit between the unit storage shed and the work table.

Abstract: It is an object of the invention to provide a document display apparatus capable of displaying a plurality of documents which are related to each other in high visibility as a whole without displaying the plurality of documents on single display means at the same time. When a document selecting area is displayed on a display screen of a display section and a single area is selected among a -plurality of areas in the document selecting area, document data corresponding to that selected single area is displayed within a document displaying area on the display screen. Accordingly, the relationship among a plurality of documents, e.g. the positional relationship, may be perceived by the positional relationship of each area in the document selecting area and specific document data may be perceived by displaying within the document displaying area.
