Abstract: A plasma display apparatus comprises a plasma display panel and an electrode driver. The plasma display panel includes a first driving electrode and a second driving electrode. The electrode driver supplies a pulse of a second polarity to the second driving electrode and a pulse of a first polarity opposite to the second polarity to the first driving electrode after a supply of a last sustain pulse of the first polarity to the second electrode. The pulse of the second polarity overlaps the pulse of the first polarity.

Abstract: The present invention discloses a method of dyeing a fiber with mugwort for effectively maintaining health and preventing diseases by applying mugwort constituents to fibers. The method comprises the steps of making a mugwort salt bath by adding mugwort powder or extraction liquor to water; heating the salt bath; putting the fiber to be dyed in the salt bath and stirring it for 10 to 30 minutes at a temperature of 50 to 100 C; rinsing and drying the fiber; and then dipping the fiber in an aqueous solution of organic binder with a temperature of 50 to 80 C for 5 to 10 minutes, drying the fiber afterwards. In another embodiment, to apply mugwort to synthetic fibers, a predetermined amount of mugwort extraction liquor may be added to a resin to be used in the process of producing fibrous yarns.

Abstract: A refrigerator includes a food storage space, an evaporator for generating cool air, and a fan for circulating the cool air to the storage space. An air diverting valve is provided which is movable in response to an opening of a door to the storage space for redirecting the air to form an air curtain across an opening of the storage space. The air diverting valve can be moved by a motor, or by a spring.
