Abstract: The present invention relates to a surface property measuring apparatus for a polishing pad used for polishing a substrate, such as a semiconductor wafer, a surface property measuring method for a polishing pad, and a surface property judging mehod for a polishing pad. The surface property measuring apparatus (30) includes: a light-emitting structure (32) configured to irradiate the polishing pad (2) with light from a plurality of directions as viewed from a polishing surface (2a) of the polishing pad (2); and a light-receiving structure (32) configured to receive reflected light traveling in a plurality of directions from the surface of the polishing pad (2).

Abstract: [Object] It is an object of the present invention to provide a shipbuilding simulation method and a shipbuilding simulation program based on a unified database capable of simulating building of a ship at detailed operation level.

Abstract: The present invention is to simulate building of a ship at a detailed operation level by executing: a product model creating step S1 of creating a product model by obtaining basic design information 1 in which a coupling relation between a completed part and a component part of the ship is clarified; a facility model creating step S2 of obtaining equipment information 21 and worker information 22 of a factory and creating a facility model; a process model creating step S3 of clarifying assembling procedure and tasks to build the completed part and creating a process model based on the product model and the facility model; a simulation step S4 to carry out time evolution system simulation based on the process model; and a time series informatization step S5 of time series digitizing a result of the time evolution system simulation into building time series information 42.

Abstract: To provide a burner that makes it possible to reduce error displacement of the distal end position of a burner main body when the burner main body is inserted. A burner (161) includes: a burner main body (162); a plurality of driving cylinders (163) that are disposed parallel to a direction of an axis line in which the burner main body (162) moves, and drive movement of the burner main body (162); a connecting member that connects the burner main body (162) and the plurality of driving cylinders (163); and a fitting member (170) that is provided between the burner main body (162) and the connecting member, and constrains relative movement in the direction of the axis line (X) and permits relative movement in a direction perpendicular to the direction of the axis line (X).
