  • Publication number: 20210180800
    Abstract: Provided is a hot-water supply device which stabilizes hot-water supply even at low water pressure. A process performed by a hot-water supply device includes: a step (S510) of detecting that hot-water supply performed by the hot-water supply device is stopped; a step (S520) of reading a set temperature of the hot-water supply from a memory; a step (S530) of calculating a target opening degree of a total water amount servo based on the read set temperature; a step (S540) of sending, to the total water amount servo, a command for setting an opening degree of a passage through which water flows from the total water amount servo into a heat exchanger to the target opening degree; and a step (S550) in which a stepping motor of the total water amount servo moves in response to the command.

  • Publication number: 20210156570
    Abstract: Provided is a hot-water supply device. A process performed by a control device of the hot-water supply device includes: a step of shifting an action mode of the hot-water supply device to an instant hot-water mode; a step of measuring an amount of water X; a step of determining that another tap interruption occurs when the amount of water X is equal to or greater than a basic flow amount Y+?; a step of stopping action of a circulation pump; a step of re-learning the amount of water X when the amount of water X is less than a basic flow amount Y??; a step of ending the instant hot-water circulation mode when an end condition of the instant hot-water mode is satisfied; and a step of measuring the amount of water X when the end condition of the instant hot-water mode is not satisfied.

  • Publication number: 20210156593
    Abstract: A hot water supply device includes: a first pipe connected to a water inlet; a flow detector detecting a flow of water in the first pipe; a heating mechanism heating the water; a second pipe through which warm water flows, connected to the first pipe via a third pipe; a circulating pump disposed in a path of the first pipe, sending the warm water in the third pipe toward the heating mechanism during operation; and a control device. Based on acceptance of an execution command of an instant hot water circulation mode, the control device operates the circulating pump, and, in response to a set hot water output temperature exceeding a limit temperature, adjusts a heating temperature of the heating mechanism, so that the temperature of the warm water becomes equal to or lower than the limit temperature.

  • Patent number: 9668943
    Abstract: A dental conditioning composition that enhances the adhesiveness of any dental material for a tooth surface by suppressing any excessive demineralization for the tooth surface and improving the polymerization activity of a dental adhesive composition by causing a polymerization catalyst included in the dental conditioning composition of the present invention to remain on the tooth surface. A dental conditioning composition having a gel character, that includes a polymerization catalyst, an acidic compound, water, and a thickening agent, and whose pH (the hydrogen ion exponent) is in a range from 0.1 to 0.9.

  • Patent number: 9631837
    Abstract: A hot water supply device 1 includes a fin-and-tube type heat exchanger (21) that applies heat to fresh water with combustion gases, and a heat exchanger casing (22) for housing the heat exchanger (21), and in order to be able reliably to determine by a simple method whether the hot water supply device is clogged by lime scale, there are provided a temperature detector (31) for detecting the surface temperature of the heat exchanger casing (22) and a control unit (7) that determines that scale has built up in the heat exchange tubing (27) of the heat exchanger (21) when the temperature detected by this temperature detector (31) is greater than a set temperature.

  • Patent number: 9345646
    Abstract: A dental curable composition that allows easily identifying the presence of the dental curable composition in an oral cavity is provided. A dental visible-light curable composition contains a fluorescent substance that generates fluorescence when irradiated with visible light. The fluorescent substance is a compound of formula A3B2C3O12 containing Ce, absorbs visible light with a peak wavelength in a wavelength range of 380 to 500 nm, and generates fluorescence with a peak wavelength in a wavelength range of 550 to 780 nm. In formula A3B2C3O12, A, B, and C are a dodecahedral eight-coordinate Y element, an octahedral six-coordinate Al element, and a tetrahedral four-coordinate Al element, respectively.
