  • Patent number: 10392787
    Abstract: A detachment sensor detects attachment and detachment of a water discharger to and from a retainer. An object sensor detects presence of an object. A controller causes water discharge triggered by detection of an object by the object sensor while the water discharger is attached to the retainer and suppresses water discharge triggered by detection of an object by the object sensor while the water discharger is detached from the retainer. The controller suppresses water discharge triggered by detection of an object by the object sensor after attachment of the water discharger to the retainer until a non-detection state of an object by the object sensor continues for a predetermined period of time.

  • Publication number: 20190084895
    Abstract: A sanitary ware includes a base, and a glaze layer formed on an outer side than the base. In color representation by the Lab color system, an absolute value of a difference (?L) between an L value obtained from observation of a part with the glaze layer formed thereon and an L value obtained from observation of a part with the glaze layer substantially unformed thereon is not more than 12, or a color difference (?E) between a color in observation of the part with the glaze layer formed thereon and a color in observation of the part with the glaze layer 5 substantially unformed thereon is not more than 14. Even though the thickness of the glaze layer varies so that the color of the base may be shown more or less through the glaze layer, there is almost no difference in color seen from the glaze layer side.
