摘要： PROBLEM TO BE SOLVED: To provide a burner for a gas cooking stove which prevents not only occurrence of a flame failure when a gas amount is throttled but also can prevent the occurrence of a red flame and lifting. SOLUTION: A plurality of gas passes 6 having various sectional areas extending radially in the direction of an outer periphery from an annular distribution chamber 4 connected to a gas mixing pipe 2 are formed, and the outer end of the gas passage forms a burner port. In the so formed burner for the gas cooking stove, the outer end of a gas passage 6a having a wide sectional area is expanded in the direction of width so that the outer end is joined with the outer end of a gas passage 6b adjoining the gas passage 6a and having a narrow section area. A partition wall 9 is situated between gas passages 8 adjoining each other and being expanded.

摘要： PROBLEM TO BE SOLVED: To provide a clothes dryer which can stably detect clogging of a filter at suppressed cost. SOLUTION: This clothes dryer 1 passes air heated by a hot water type heat exchanger 6 to an exhaust duct 8 via a suction duct 5 and a rotary drum 3 by operating a suction/exhaust fan 9 to dry clothes S in the rotary drum 3. A differential pressure sensor 16 to detect the differential pressure between the upstream side and the downstream sideof the heat exchanger 6 outputs detection signals of the differential pressure changing corresponding the flow rate of air passing through the suction duct 5 to a controller 2 which judges generation of clogging in a filter 6 when the differential pressure comes to below a prescribed level, informs a user of generation of clogging in the filter 26, and prohibits execution of the drying operation.

摘要： PROBLEM TO BE SOLVED: To provide an absorption refrigerator, in which the infiltration of intermediate-concentration absorbent into the flow path of solvent vapor ca be detected early, a detection means such as a sensor can be easily installed in the refrigerator, and efficiency decrease of the cooling cycle can be recovered at a low cost. SOLUTION: The absorption refrigerator comprises a high-temperature regenerator 1, a low-temperature regenerator 3, a condenser 8, an evaporator 9, an absorber 7, and an absorption pump P. The high-temperature regenerator 1 heats and boils the low-concentration absorbent, and separates it by a separating tube 2 into solvent vapor and the intermediate-concentration absorbent. In the low-temperature regenerator 3, the intermediate-concentration absorbent is heated by condensation heat of the generated absorbent vapor, and separated into solvent vapor and a high-concentration absorbent. The condensed solvent is passed through a solvent flow-path 60 to the condenser 8. The pump P circulates the low concentration absorbent to the high- temperature regenerator 1. The refrigerator is provided with a temperature sensor 62 for detecting the infiltration of the intermediate-concentration absorbent into the solvent flow-path 60 and reduces the circulation amount of the low-concentration absorbent by an output of the pump P.

摘要： PROBLEM TO BE SOLVED: To inexpensively manufacture an annular burner that can obtain a large dynamic input ratio by eliminating the occurrence of such a trouble as the accidental fire, backfire, etc., caused when a thermal power adjusting lever is operated for abruptly reducing the quantity of a fuel gas. SOLUTION: This annular burner is manufactured in such a way that gas passages 7 extended outward in the radial directions from an annular distribution chamber 6 communicating with a gas mixing pipe 1 are formed in the chamber 6 and, at the same time, the upper surfaces 7a of the passages 7 are formed in slopes which are gradually inclined upward toward the outside and the external ends of the passages 7 are constituted in the burner port 9 of the burner. In the burner, a recessed unburnt gas reservoir 11 the lower part of which is expanded more than its upper part is formed closely to the outside of the port 9. The reservoir 11 is constituted by moving the upper edges of the partition walls of the gas passages in the port 9 inward than the lower edges of the walls and formed by cutting off the upper edges of the partition walls of the gas passages in the port 9.

摘要： PROBLEM TO BE SOLVED: To solve the problem that cold water flows for a while after the water is turned on when there is a faucet away from a water heater, a large amount of cold water is allowed to flow uselessly until change is made to the hot water, and the change from cold water to hot water cannot be detected visually or the like and hence it is troublesome to confirm it with hands and one becomes irritated or the like. SOLUTION: A hot water outflow device 1 is mounted near the faucet 3. In the hot water outflow device 1, cold water being present at a hot water passage 4 between the water heater 2 and the hot water outflow device 1 is accumulated in a water storage tank 6 after the faucet 3 is opened. When the hot water reaches the hot water outflow device 1, the hot water is guided to the faucet 3. As a result, cold water until hot water reaches the hot water outflow device 1 from the water heater 2 cannot become useless, thus saving water. Also, the need for confirming the change from the cold water to hot water is eliminated for preventing troubles.
