  • Patent number: 6463766
    Abstract: A washing machine includes a wash tub, a water-supply mechanism for supplying water into the wash tub, and a disposition section in which a solid antimicrobial agent containing an organic compound having a nitrogen-halogen atomic combination is disposed. The disposition section is provided in the water-supply mechanism. The antimicrobial agent is brought into contact with water thereby to release hypohalogenous acid into the water.

  • Patent number: 5467078
    Abstract: A communicating system has at least two air conditioning machines which are connected to a primary interface and a secondary interface, respectively. The primary interface is connected to a primary remote controller having a display. The secondary interface is connected to a secondary remote controller having a display and the primary interface. When the state of all air conditioning machines is to be changed by a command from the primary remote controller, firstly all displays are caused to display the now run mode of the air conditioning machines substantially at the same time. After that, the operating states of the air conditioning machines are a predetermined interval.
