IPC: F24H1/10
Filed: 1988-12-30
Abstract: PURPOSE:To provide a controlling over a mixing valve under the best condition within a narrow range and improve a durability of the mixing valve by a method wherein a temperature in a hot water feeding system to cause flow rates of the hot water feeding system and a cold water feeding system to be equal or substantially equal to each other is calculated in reference to a set temperature and a cold water feeding temperature, and then an amount of combustion in a burner of a heat exchanger is controlled with the temperature of the hot water feeding system as a set value. CONSTITUTION:A cold water feeding system C branched at an upstream side of a heat exchanger 2 of a hot water heater 1 and merged at a downstream side is provided. The cold water feeding system C and a hot water feeding system H are merged through a mixing valve 3 capable of adjusting a rate of flow without varying a total flow rate of the cold water feeding system C and the hot water feeding system H. A controlling means 5 may get a temperature of the hot water feeding system H in which a flow rate of the hot water feeding system H and a flow rate of the cold water feeding system C are equal to each other or substantially equal to each other in reference to the set temperature and a cold water feeding temperature and then control an amount of combustion in a burner 6 of a heat exchanger 2 with a temperature of the hot water feeding system H as the set value. In regard to a variation of the cold water feeding temperature or the set temperature, it may correspond to a variation of the set value of the temperature of the hot water feeding system H, the mixing valve 3 may have always the equal flow rates of the hot water feeding system H and the cold water feeding system C or they are kept substantially equal to each other and then a feed-back control is carried out, so that the mixing valve 3 is controlled within a narrow range and under the condition of the best controlling characteristic.

IPC: B29B15/12
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To provide prepreg that hardly causes the problems on blurring and warpage of laminated sheets and its production process. SOLUTION: In the prepreg that is prepared by impregnating the base material with substantially solvent-free thermosetting resin, the thermosetting resin composition layers are made almost equal to each other in their surface thickness on both their front and back faces.
