  • Patent number: 10921026
    Abstract: In a heating heat-source apparatus having input circuits configured to receive pieces of mutually independent heating demand information, an abnormality related to an operation for setting one input circuit among the input circuits to a use state is detected and reported. Input circuits receive heating demand information. An operation part receives an operation for setting one input circuit of the input circuits to a use state. A CPU receives heating demand information transmitted from the input circuit in the use state while receiving specified information for specifying the input circuit in the use state from the operation part. Each piece of heating demand information is voltage information having a predetermined voltage range. The CPU reports an abnormality related to an operation for setting when voltage information transmitted from the input circuit in the use state deviate from a voltage range specified in the specified information.

  • Patent number: 10824178
    Abstract: The disclosure provides a heating and hot water supply apparatus which includes a heating circulation path configured to circulate a heated heating medium with a heating terminal, and a bypass path branched from the heating circulation path for causing the heating medium to flow therethrough without passing through the heating terminal. A hot water supply heat exchanger is disposed in the bypass path. A division ratio of the heating medium from the heating circulation path to the bypass path is controlled by a distribution valve. The division ratio is increased from a first value to a second value when a reservation preheat control is started during the heating operation according to a start reservation time of hot water supply operation reserved by a timer, and set to a third value greater than the second value during a simultaneous operation of the hot water supply and the heating operation.

  • Patent number: 8263607
    Abstract: Provided is a compound useful as an N-type Ca2+ channel blocker. As a result of intensive studies of compounds having an action of blocking N-type Ca2+ channels, the present inventors found that a tetrahydroisoquinoline compound of the present invention having a substituent at the 1-position has an action of blocking the N-type Ca2+ channels, an antinociceptive pain action, an antineuropathic pain action, an abdominal pain-inhibitory action and an opioid-induced constipation-improving action, and the present invention has been completed based on these findings.
