20150253035 | BURNER, COMBUSTION APPARATUS, WATER HEATING APPARATUS AND COMBUSTION METHOD - A burner includes a first burner port that generates a first flame, a gap that surrounds the first burner port, and a plurality of second burner ports that are disposed on either side of the gap, the second burner ports generating second flames to hold the first flame. The first burner port combusts a first mixture (lean mixture) to generate the first flame (lean flame). The first mixture includes air more than fuel gas. A gap that surrounds the first burner port is formed. A plurality of the second burner ports are arranged on either side of the gap. The second burner ports combust a second mixture (rich mixture) to generate the second flames (rich flames) and hold the first flame. The air-fuel ratio of the second mixture is smaller than the first mixture. | 09-10-2015 |
20140379147 | HOT WATER SUPPLY SYSTEM, WATER HEATER AND HOT WATER SUPPLY CONTROL METHOD - A hot water supply system includes a plurality of water heaters, one of which is designated as a master, and the rest(s) of which is/are designated as (a) slave(s). A control unit that is provided for each of the water heaters operates a water heater, for which the control unit is provided, as the master or the slave, the master controls the slave(s), and the master and the slave(s) control hot water supply. | 12-25-2014 |
20120248141 | DRINKING WATER DISPENSER - A drinking water dispenser heats and cools drinking water supplied from a water supply bottle, and provides heated and cooled drinking water. The dispenser includes a cold water tank, a hot water tank, a water supply pipe, a valve, a by-pass pipe, a by-pass valve and a control unit. The valve opens and closes a water outlet for taking in the drinking water from the water supply bottle according to a level of the drinking water in the cold water tank, limits supply of the drinking water to the cold water tank, and, while the water outlet is shut, suppresses convection of the drinking water and/or heat of the drinking water between the water supply bottle and the cold water tank. | 10-04-2012 |
20120156768 | PRESSURE AND CIRCULATION CULTURE APPARATUS AND PRESSURE AND CIRCULATION CULTURE SYSTEM - The pressure and circulation culture apparatus includes a holder (culture chamber part), a pressure transmission part and a culture solution circulation line (culture circuit). The holder is a means that reserves culture solution and that holds a cultured object. The pressure transmission part is a means that communicates with the holder and transmits an external pressure to the culture solution. The culture solution circulation line is a means that is connected to the holder via the pressure transmission part, and circulates the culture solution through the holder via the pressure transmission part. Such a structure is included, and an external pressure is made to operate on the culture solution via the pressure transmission part to allow pressure on the cultured object in the holder and circulation of the culture solution in the holder. | 06-21-2012 |
