  • 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: 8032043
    Abstract: In case new and old toners may be mixed, a developing bias is set as follows. The time is first clocked. The number of times toner is replenished from a hopper into a buffer for a clocked period is counted. If a replenishment amount per clock time is a threshold value or higher, considering that new and old toners are mixed, the setting of the developing bias is changed. An electric field intensity between a developing roller and a photoconductor is set to cause normally-charged toner to fly in an image area but not to fly in a background area. No image fogging is therefore generated in the background area. Thus, an image forming apparatus and method capable of preventing low-charged toner and oppositely-charged toner generated by mixing of new and old toners from adhering to the background area of an electrostatic latent image on the photoconductor, thereby avoiding generation of image fogging.

  • Patent number: 8004395
    Abstract: An instrument panel display system displays vehicle information, amenity information, and safety information as images. In this instrument panel display system, data (image data, image layout data, and image output control data) for displaying the images are generated in a shared manner by a vehicle system processor, an amenity system processor, and a safety system processor. On account of this, the stability of image display on an instrument panel of a vehicle or the like is improved and hence safety of driving is increased.
