Abstract: A display unit that displays a system-configuration setting screen including a system-configuration display area and a list display area; a collaboration-software product-specification storage unit that stores therein a setting target of collaboration software and network information in association with each other for each collaboration software, the network information indicating a network used for connection of the setting target; a collaboration-software display unit that list-displays collaboration software stored in the collaboration-software product-specification storage unit as a component list in the list display area; an automatic connection checking unit that determines whether the collaboration software selected from the component list and arranged in the system-configuration display area can be connected to the setting target based on the network information; and a collaboration-software arrangement unit that connects, an image representing the collaboration software to a system displayed in the s

Abstract: The present invention provides a metal member that is used so that there is a portion that is exposed to the atmosphere in a float bath, and with which diffusion of Fe into the float bath is inhibited and thereby preventing the defect from being generated on the surface of a plate glass. The present invention relates to a metal member with a film for a float glass manufacturing equipment that has a portion exposed to the atmosphere in a float bath in which the film has a mean thickness of from 50 to 500 ?m and contains Ni and/or Co, Cr and Al2O3 as main components; the Al2O3 content in the film is from 5 to 40% by volume; the Al2O3 is present in a thin film state in the surface direction of the metal member, inside the film; and the metal member contains Fe in an amount of from 40 to 98% by mass and has the film on the exposed portions.

Abstract: An apparatus 10 for producing a plate glass, comprising a bath 14 for float-forming for reserving a molten metal 16 for forming a band-shaped plate glass having a predetermined thickness by feeding a molten glass ribbon 20 in a predetermined direction on the molten metal 16, and a pair of partition walls 46 provided substantially above left and right edges 22 of the molten glass ribbon 20 and substantially along the edges 22 to partition a space above a bath surface of the molten metal into an upper space A above a region covered with the molten glass ribbon 20 and upper spaces B above regions not covered with the molten glass ribbon 20; wherein the partition walls 46 each has a vertically dividable structure dividable into an upper partition wall 46A and a lower partition wall 46B, and the lower partition wall 46B is constituted by strip-shaped lower strip members 58 provided continuously to each other in a lateral direction, and the strip members 58 are configured to be removable or openable from the upper
