The purpose of the present invention is to provide a magnetic fluid display in which a magnetic fluid moves in response to a magnetic field and which may display a unique visual image according to the meeting and parting of the magnetic fluid. A magnetic fluid display according to the present invention comprises: a display unit including a transparent liquid into which a magnetic fluid is injected; and a magnetic field generating unit for applying a magnetic field to the magnetic fluid at a rear surface of the display unit. When the magnetic field is applied, the magnetic fluid moves in the transparent liquid in a directional manner, so that an image may be displayed on the display unit.

Magnetic fluid display

The purpose of the present invention is to provide a magnetic fluid display in which a magnetic fluid moves in response to a magnetic field and which may display a unique visual image according to the meeting and parting of the magnetic fluid. A magnetic fluid display () according to the present invention comprises: a display unit () including a transparent liquid into which a magnetic fluid () is injected; and a magnetic field generating unit () for applying a magnetic field (M) to the magnetic fluid () at a rear surface of the display unit (). When the magnetic field is applied, the magnetic fluid moves in the transparent liquid in a directional manner, so that an image may be displayed on the display unit.

Disclosed herein is an apparatus for processing a medium, including: a accepting unit in which the medium is loaded; a dispending unit from which the medium is withdrawn; a medium discriminator configured to discriminate a denomination of the medium loaded into the accepting unit; a plurality of medium storage boxes configured to each discriminate and store the medium by denomination of the medium discriminated by the medium discriminator; and a controller configured to store the medium loaded through the accepting unit by the same denomination in the medium storage box and withdraw the loaded medium from the medium storage box according to a predetermined withdrawal criterion.

Medium processing apparatus and method thereof

The present invention relates to a sewage treatment system using granules, and more particularly, the sewage treatment system includes: an anoxic tank which has a sewage inlet port into which sewage is introduced; an anaerobic tank which is connected to the anoxic tank; intermittent aeration tanks which are connected to the anaerobic tank, have two or more separately divided spaces, and have, in the spaces, granules and aeration devices that alternately operate; and a settling tank which is connected to the intermittent aeration tanks, and the sewage treatment system is operated by a method including: a first step of introducing sewage; a second step of allowing the introduced sewage to pass through the anoxic tank and to be supplied with carbon; a third step of allowing the sewage passing through the anoxic tank to be introduced into the anaerobic tank; a fourth step of allowing the sewage passing through the anaerobic tank to be introduced into a first intermittent aeration tank and a second intermittent aeration tank which include the aeration devices and the granules including nitrogen treatment microorganisms; a fifth step of allowing the first intermittent aeration tank to be in an aeration state and the second intermittent aeration tank to be in a non-aeration state; and a sixth step of allowing the first intermittent aeration tank to be in the non-aeration state and the second intermittent aeration tank to be in the aeration state.
