Abstract: The present invention provides a solid oxide fuel cell system capable of preventing excess temperature rises while increasing overall energy efficiency. The present invention is a solid oxide fuel cell system, including: a fuel cell module, a fuel supply device, a heat storing material, and a controller which, based on power demand, increases the fuel utilization rate when output power is high and to lower it when output power is low, and changes the electrical power actually output at a delay after changing the fuel supply amount. The controller has a stored heat estimating circuit for estimating the residual heat based on fuel supply and on power output at a delay relative thereto. When a utilizable amount of heat is accumulated in the heat storage material, the fuel supply is reduced so that the fuel utilization rate increases relative to the same electrical power.

A showerhead 3 furnished with an outer cylinder 31 in which a metal plate is plastically deformed and formed into a cylindrical shape in which the base end portion thereof is left open; and a water conduit member 32 which is inserted from the open end of the base end portion side into the outer cylinder to supply hot or cold water supplied from a hose into outer cylinder 31; whereby a gripping portion 311 for holding outer cylinder 31 by hand is provided on the base end portion of outer cylinder 31, and a spray portion 33 is provided in which multiple spray holes 33b are formed to spray hot or cold water supplied by water conduit member 32 to the front end portion side of outer cylinder 31.

Abstract: There is provided a water area equipment that can inhibit water scale formation and further can very easily remove formed water scale. In the water area equipment, silicic acid polymerization can be inhibited to reduce water scale formation, and, further, formed water scale can very easily be removed, for example, by lightly wiping off the water scale. The water area equipment on which water from a water supply source can be poured comprises a unit configured to add an inhibitor for silicic acid polymerization to water deposited as water residual on the surface of the water area equipment and can inhibit water scale formation and can allow formed water scale to be easily removed. A specific unit that inhibits the polymerization of silicic acid is configured to enhance the acidity of water and, for example, to adjust pH of residual water to 1.5 to 5.5.

Abstract: A hot and cold water mixing valve including a temperature adjusting dial, and a cylindrical casing having formed therein a hot water inlet and a cold water inlet is provided with a control valve member in which one end thereof is subjected to a load from a biasing member and the other end is subjected to a load from an actuator. By balancing between the loads applied by the biasing member and the actuator, a mixture ratio between the hot water which flows in through the hot water inlet and the cold water which flows in through the cold water inlet is adjusted. A temperature adjuster adjusts a position of the control valve member through the biasing member and includes a tapered skirt portion, which spreads in a radial direction, at an end on the control valve member side thereof.
