    摘要: An apparatus and a method for applying a fluid, which enable an application amount of the fluid to be stabilized even at the start of fluid discharge and at the end of the fluid discharge. The apparatus includes an application head and a control unit, whereby operational control is carried out so that a discharge member is rotated and moved in a discharge direction along an axial direction of the discharge member when the fluid is to be discharged, while the rotation of the discharge member is stopped and the discharge member is moved in a direction opposite to the discharge direction when the discharge is to be stopped. The application amount of the fluid to be applied can be stabilized even at the start of fluid discharge and at the end of the fluid discharge.

    摘要: A fluid rotating apparatus includes a casing having gas inhaling inlet and a gas discharge outlet, rotors driven in the casing by a driving mechanism and having fluid-transporting grooves which engage each other in synchronous rotation, and bearing portion for supporting the rotors. A communicating path is formed at one of the rotor and the casing for communicating a gas discharge-side inner space and a space defined by an inner surface of the casing and the fluid-transporting groove of an outer surface of each rotor with each other. The gas discharge-side inner space is defined by an end surface of the rotor opposite to a gas inhaling-side surface thereof, and a sealing portion is formed between the rotor and the casing to prevent fluid from flowing into the gas discharge-side inner space.
