|20120115093||COMBUSTION APPARATUS AND METHOD FOR COMBUSTION CONTROL THEREOF - 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.||05-10-2012|
|20120090560||WATER HEATER AND CONTROL METHOD THEREFOR - 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.||04-19-2012|
|20120090341||WATER HEATER AND CONTROL METHOD THEREFOR - A water heater includes one or a plurality of heat pumps that heat tap water or return water from a hot water supply part, a circulation line that supplies hot water heated in the heat pumps to the hot water supply part, and introduces the return water from the hot water supply part to the heat pumps, an incoming water pipe that joins to between the hot water supply part in the circulation line and the heat pumps and supplies the tap water, a circulation pump that returns the return water to the heat pumps and circulates the return water through the circulation line, and a control unit that controls operation or stop of the circulation pump according to driving operation time or elapsed stop time by linking a combustion process of the heat pumps.||04-19-2012|
|20120037096||COMBUSTION APPARATUS, METHOD FOR COMBUSTION CONTROL, COMBUSTION CONTROL BOARD, COMBUSTION CONTROL SYSTEM AND WATER HEATER - A combustion apparatus includes combustion means generating combustion exhaust by combustion of fuel, heat exchange means exchanging heat of the combustion exhaust, and exhaust dilution unit supplying dilution air after the heat exchange by the heat exchange means and diluting the combustion exhaust after the heat exchange, and controls a temperature of the combustion exhaust after the heat exchange below a predetermined temperature by dilution by air supply.||02-16-2012|
|20110313637||COMBUSTION APPARATUS AND METHOD FOR COMBUSTION CONTROL - A combustion apparatus (water heater) includes a combustion means (burner) combusting fuel, at least two flame detecting means (flame rods) detecting whether there is a flame or not in the combustion means, a determination unit (control device) determining whether or not to be a misfire based on detected results of the flame detecting means, and a control unit (control device) stopping supply of the fuel to the combustion means in response to a determined result of the determination unit.||12-22-2011|
|20110203788||HOT WATER SUPPLY APPARATUS AND HEAT MEDIUM CONTROL METHOD - A hot water supply apparatus using a heat medium provides a heat medium circulation path that circulates the heat medium, a heat medium pump that pumps the heat medium into the heat medium circulation path, a heat source that generates heat heating the heat medium, a heat medium heat exchanger that exchanges heat generated by the heat source for the heat medium, a hot water supply heat exchanger that exchanges heat of the heat medium circulating in the heat medium circulation path for clean water, and a control unit that sets the heat medium in the heat medium circulation path in a predetermined temperature and controls the rotating speed of the heat medium pump and the combustion amount of the heat source according to a heat requirement.||08-25-2011|

|20100205958||EXHAUST HEAT RECOVERING METHOD, EXHAUST HEAT RECOVERING APPARATUS AND COGENERATION SYSTEM - 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).||08-19-2010|
|20090298181||METHOD OF CULTIVATING CELL OR TISSUE - A method for cultivating a culture of a cell, tissue, etc. There is provided a method of cultivating a culture including a cell or tissue (cell construct), imparting bending motion to the culture. By virtue of applying bending force to a culture of a cell, tissue, etc. (cell construct) to thereby curve the culture, continuous compression and extension in a direction of thickness from a concave portion toward a convex portion thereof are induced. The physical stimulation and deformation not attained by conventional pressurization, shear and tension, then can be loaded on the culture to thereby realize the culture appropriate for restoration of tissue at a region accompanied by bending.||12-03-2009|
|20090209035||CELL OR TISSUE CULTIVATION APPARATUS AND METHOD OF CULTIVATION - 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.||08-20-2009|
