Abstract: A sodium-sulfur battery is used for a longer period than a lifetime thereof. The sodium-sulfur battery includes a negative electrode active material and a positive electrode active material. The negative electrode active material includes sodium. The positive electrode active material includes sulfur and sodium polysulfide. An apparatus for controlling the sodium-sulfur battery includes a charge and discharge controller and a temperature controller. The charge and discharge controller controls charge and discharge of the sodium-sulfur battery. The temperature controller maintains the sodium-sulfur battery at a first temperature at which sodium, sulfur, and sodium polysulfide are liquefied in an operation period during which the charge and discharge controller causes the sodium-sulfur battery to be charged and discharged, and maintains the sodium-sulfur battery at a second temperature at which sodium and sulfur are liquefied and sodium polysulfide is solidified in a non-operation period during which the charge and discharge controller causes the sodium-sulfur battery not to be charged and discharged.

Abstract: A composite substrate for an electro-optic element is disclosed. The composite substrate includes: an electro-optic crystal substrate having an electro-optic effect; a low-refractive-index layer being in contact with the electro-optic crystal substrate and having a lower refractive index than the electro-optical crystal substrate; and a support substrate bonded to the low-refractive-index layer at least via a bonding layer. A plurality of interfaces located between the low-refractive-index layer and the support substrate includes at least one rough interface having a roughness that is larger than a roughness of an interface between the electro-optic crystal substrate and the low-refractive-index layer.

Abstract: When in the independent system: a natural energy generating apparatus, a storage battery system, a power generator, and a first load is connected to a power supply system; the natural energy generating apparatus supplies generated power to the power supply system; the storage battery system is a regulated power supply; and the power generator performs a constant power operation, information indicating states of the natural energy generating apparatus, the storage battery system, the power generator, the first load, and a second load is obtained. Operations of the natural energy generating apparatus and the power generator, connection of the second load to the power supply system, and paralleling off the second load from the power supply system are controlled based on the information so that a demand-supply balance of power in the independent system is maintained, with the first load maintained to be connected to the power supply system.
