Abstract: A cultivation apparatus and a cultivation method of a culture such as a cell or tissue. Provided are an incubator unit for accommodating a culture and a lever that penetrates through the incubator unit and can move in circular arc around a fulcrum as a center, the fulcrum being set at a wall of the incubator unit or in the vicinity thereof, then displacement is imparted to the culture by operating the lever. Bending force can be acted on the culture (cell construct) such as a cell or tissue, so that without any increase or decrease of a culture fluid in the incubator unit, namely, without any increase or decrease of pressure to the culture fluid, displacement required for cultivation can be imparted to the culture in the incubator unit. By curving, continuous compression and extension are generated in a direction of thickness from a concave portion to a convex portion of the curving.

Abstract: A hot water supply system including a water heater that includes a storage unit storing at least device information of another water heater, and performs hot water supply control by which the water heater cooperates with the other water heater, these water heaters being able to supply hot water according to a hot water supply request; one or a plurality of the other water heater that is connected to the water heater in parallel, and supplies hot water according to the hot water supply control by the water heater; communication connection means that communicably connects the water heater and the other water heater; water supply means that supplies water to the water heater and the other water heater; and hot water supply means that supplies hot water heated by the water heater and the other water heater to a hot water supply destination.

Abstract: A combustion apparatus. Combustion means (burner) generates flame by combustion. Air supply means (intake fan) supplies air to the combustion means. Flame current detecting means (FRB) is set at a certain detection position and detects a flame current value included in the flame which is generated by the combustion means. Determination means (control device) determines a distribution where the flame current value that is detected is included for the flame current detecting means. Control means (control device), when the flame current value is not included in a distribution, which is set as normal values, outputs a control command of increasing or decreasing at least one of the supply of the air by the air supply means and the supply of fuel based on a determination result by the determination means.

Abstract: A water heater includes combustion means (burner) that combusts fuel and generates exhaust; heat exchange means (primary heat exchanger and secondary heat exchanger) that exchanges heat of the exhaust for supplied water; bypassing means (bypass pipe) that makes the supplied water flow to an outlet of the heat exchange means; exchanged heat temperature detection means (exchanged heat temperature sensor) that detects temperature of the supplied water after heat exchange; flow rate adjustment means (bypass valve) that adjusts a volume of the supplied water flowing into the bypassing means and the heat exchange means; and a control unit that controls the flow rate adjustment means so as to make a predetermined volume of the supplied water or over flow to the heat exchange means.

Abstract: A combustion apparatus (water heater) includes a combustion unit (burner) combusting fuel, at least two flame detector (flame rods) detecting whether there is a flame or not in the combustion unit, a determination unit (control device) determining whether or not there is a misfire, based on detected results of the flame detectors, and a control unit (control device) stopping supply of the fuel to the combustion unit in response to a determined result of the determination unit.

Abstract: A first heat medium is circulated in a first circulating path (engine cooling circuit) of a heat source (engine) to cool the heat source down by the first heat medium, and exhaust heat from the heat source is absorbed by the first heat medium. A second heat medium is circulated in a second circulating path (exhaust heat recovering circuit) to exchange heat of exhaust air with the second heat medium, and heat of the first heat medium is exchanged with the second heat medium circulating in the second circulation path. The heat of the second medium to which heat is applied due to these heat exchanges is stored in heat storage means (heat storage tank).
