PROBLEM TO BE SOLVED: To provide a fluid treatment apparatus and a fluid treatment method for more stably carrying out uniform treatment.SOLUTION: For at least one kind of fluid, fluid treatment is carried out between treatment faces in treatment parts which come close to and apart from each other and of which one is rotated relatively to the other by using at least two kinds of fluids containing at least one kind of object to be treated. A first fluid is introduced between treatment faces 1, 2 by employing a micro-pump effect caused by a recessed part 13 formed in the treatment face from the center of the treatment face of the rotating one. Independently of the introduced fluid, a second fluid is introduced through another channel d2 having an aperture part d20 communicated with the space between the treatment faces and treatment is carried out by mixing and stirring the fluids between the treatment faces 1, 2. The introduction direction of the second fluid from the aperture to the treatment faces is slanted to the treatment faces.

PROBLEM TO BE SOLVED: To supply material gas containing component gas of an equal concentration ratio, by controlling to be a different flow rate, to a plurality of gas supply openings of a semiconductor manufacturing chamber.SOLUTION: The gas supply system includes a plurality of gas supply devices 10 connected respectively to gas supply openings C. Each of the plurality of gas supply devices 10 includes: a plurality of component gas supply pipes 1 through which various types of gas flows separately; a flow rate control mechanism 4 which controls the flow rate of gas respectively that flows through the component gas supply pipes 1; and a material gas supply pipe 2 which bundles the component gas supply pipes 1. The flow control mechanism 4 includes a flow control valve V, an individual pressure sensor P, and a fluid resistance element R provided to the component gas supply pipes 1 in the order starting from an upper stream side, a common pressure sensor PC provided to the material gas supply pipe 2, and a control part 41 which calculates a gas flow rate flowing through the component gas supply pipes 1 based on a pressure measured with the individual pressure sensor P and a pressure measured with the common pressure sensor PC, and then, based on the calculated gas flow rate, controls the flow control valve V.
Abstract:
PROBLEM TO BE SOLVED: To provide a hand drying device at a sink, capable of being provided in a commercial washroom.SOLUTION: The fixture serving both as a purpose of the sink and a purpose of a hand wash basin is installed with both a water tap and a hand dryer. The water tap has a water pouring port projecting above the hand wash basin of the sink, and the hand dryer is installed with two or more hand dryer nozzles, one pair by one pair to the respective hands of a user. A left hand nozzle is present on the left side of the water pouring port, and a right hand nozzle is present on the right side of the water pouring port. Specifically, the water pouring port plays a part as a division partition between two hand dryer nozzles. Thereby, correct utilization of the hand dryer is promoted. The fixture can be installed to the sink or be mounted on a wall above the sink.
Abstract:
PROBLEM TO BE SOLVED: To provide a lithography apparatus in which the possibility of containing bubbles is reduced at least partially, and/or the thermal load due to vaporization is reduced at least partially.SOLUTION: A fluid handling structure is configured to supply an immersion liquid to a space defined between a projection system and a counter surface facing the fluid handling structure. The fluid handling structure comprises a main body having a lower surface, a movable member which is movable for the main body, and a self-adjustment mechanism for maintaining a clearance of a specific size between the bottom surface of the movable member and the counter surface, regardless of the size of the clearance between the lower surface and the counter surface.
