Abstract: A startup method and startup program for microgrid that enable to stably start up the microgrid without producing frequency fluctuation is provided. An embodiment of the present disclosure is a startup method for microgrid configured by a plurality of inverter power supplies independently sharing a load and divided into a master that starts up first and a slave that starts up secondly and later, the startup method comprising: a master initial startup step of initially starting up the master in a CVCF mode; a slave initial startup step of initially starting up the slave in a grid interconnection mode; and a control mode changing step of the master and the slave changing control modes thereof when output fluctuation of the master and the slave becomes a predetermined threshold or less or when the master and the slave or other inverter power supplies become a predetermined operation state while output voltage of said master and said slave becomes a predetermined threshold or less.

Abstract: A rolling guide device includes a track member, a moving member, and a plurality of rolling bodies. Rolling-body rolling surfaces that come into contact with an rolling-body outer circumferential surface of a rolling body are respectively formed in wall surfaces of a pair of wall portions included in the track member facing each other, a scraper including a pressing portion that presses the rolling-body rolling surfaces is turnably installed in the moving member, the scraper includes at least an attachment portion and a pressing portion, and is formed such that a frictional force of the pressing portion with respect to the rolling-body rolling surfaces is smaller than a frictional force of the attachment portion with respect to an attachment shaft formed in the moving member.

Abstract: To promote appropriate mutual understanding among a plurality of users, an information processing device accepts, as a first instruction, a change instruction for changing a visualization screen that visualizes a model representing preset physical entities, the change instruction including at least one instruction of an index addition instruction, a control change instruction, a display change instruction, and a comment addition instruction. The device displays a visualization screen according to the accepted first instruction on a preset display unit. After the display of the visualization screen corresponding to the first instruction, the device accepts, as a second instruction, at least one instruction of the index addition instruction, the control change instruction, the display change instruction, and the comment addition instruction. When the second instruction has been accepted, the device notifies the fact that the visualization screen has been changed to a preset notification destination.
