Abstract: A process for producing an optical fiber including a glass fiber, a primary resin coating layer which covers the periphery of the glass fiber, and a secondary resin coating layer which covers the periphery of the primary resin coating layer, wherein the primary resin coating layer is formed by curing a curable resin composition which includes one or more oligomers, one or more monomers, and a reaction initiator, the curable resin composition containing a one-end-capped oligomer in an amount of 30% by mass or larger based on all the oligomers. The optical fiber produced by this production process does not deteriorate in low-temperature transmission loss, because the primary resin coating layer is inhibited from generating voids even when having a low Young's modulus.

Abstract: A control device for a power generation system whereby power is generated by a first power source that operates by burning a fuel. The control device identifies, on the basis of a pressure difference in a prior-stage mechanism that supplies the fuel to the first power source, a fuel capacity that compensates for the pressure difference in the prior-stage mechanism. The pressure difference is the difference between a pressure set for the fuel before a load change in the prior-stage mechanism and a pressure set for the fuel after the load change in the prior-stage mechanism. The control device calculates a fuel supply command value, which is a command value for adjusting the amount of fuel supplied to a fuel supply device that supplies the fuel to the first power source, and is output to the fuel supply device using a fuel supply acceleration command value.
