Abstract: A bushing for producing glass fibers, including: a plurality of nozzles made of platinum or the like to discharge molten glass; and a base plate made of platinum or the like. A coating layer is preferentially formed on an outer circumferential face in a tip part on the side of glass discharge of the nozzle, and a width of the coating layer is 5% or more and 95% or less with respect to the entire length of the nozzle. The base plate includes a non-coating area. Areas of the nozzles and the base plate not provided with the coating layer act as a sacrificial metal for protecting the nozzle tip parts. In consideration of the sacrificial metal, a coverage rate P of the coating layer in the nozzle tip parts calculated e with a prescribed equation is preferably 5% or more and 350% or less.

Abstract: In an operation method of a multi-shaft combined cycle plant, a low-load mode in which an output of the multi-shaft combined cycle plant is adjusted by adjustment of only an output of a gas turbine and a high-load mode in which the output of the multi-shaft combined cycle plant is adjustable by adjustment of the output of the gas turbine and adjustment of an output of a steam turbine are switched according to a demanded load. In the low-load mode, steam at a standby flow rate at which the steam turbine is capable of maintaining a predetermined initial load is supplied to the steam turbine, and the initial load is applied to the steam turbine.

Abstract: An organic EL device with which occurrence of leakage current between electrodes can be prevented includes: a substrate; a first electrode layer separating groove that separates a first electrode layer into small pieces; a function layer separating groove that separates a function layer into small light emitting regions; and a unit light emitting element separating groove extending from a second electrode layer to the function layer and separating the second electrode layer into small pieces. One of the small pieces of the first electrode layer, one of the small light emitting regions, and one of the small pieces of the second electrode layer structure a unit organic EL element, electrically connected in series. The average width of the unit light emitting element separating groove at the second electrode layer is wider than the average width of the unit light emitting element separating groove at the light emitting portion separating layer.
