Abstract: A pixel includes: a light emitting element; a first transistor including a gate electrode electrically connected to a first node, a second node to which a first power voltage for driving the light emitting element is to be applied, and a third node electrically connected to the light emitting element; and a bias control transistor configured to be controlled in operating timing thereof by a bias control signal, and configured to switch electrical connection between the second node and a bias power line for transmitting a bias voltage. In one frame period, a voltage level of the bias voltage to be applied to the second node sequentially increases.

Abstract: Disclosed is an anticorrosion paint for preventing steel materials from corrosion by using polyaniline as an anticorrosion pigment. The anticorrosion paint has an excellent anticorrosion effect, long persistence of the anticorrosion effect, high durability and superior coating property controlling the anticorrosion effect, without using metal causing environmental pollution as an anticorrosion pigment. Especially, in the anticorrosion paint, the top coat paint for improving the protection of the primer coat paint and the anticorrosion effect. The top coat paint includes 40 to 89 wt % of matrix resin, 5 to 54 wt % of colored pigment, 1 to 50 wt % of dopants and 5 to 54 wt % of mixed solvents, and the primer coat paint includes 3 to 49 wt % of the polyaniline, 40 to 86 wt % of the matrix resin, 1 to 47 wt % of the dopants and 10 to 56 wt % of the mixed solvents. The anticorrosion paint plays a role in exerting persistently the excellent anticorrosion effect without causing environmental problem.

Abstract: A binder composition for a photocatalytic coating is disclosed. The binder composition comprises 60-80 wt. % of a first monomer which is a non-fluoro containing monomer selected from the group consisting of acrylic monomers, methacrylic monomers, and mixtures thereof, having an aliphatic group and 20-40 wt. % of a second monomer which is at least one monomer selected from the group consisting of a fluoro containing monomer and a silicone monomer. The fluoro containing monomer is selected from the group consisting of styrene monomer, acrylic monomer and methacrylic monomer.

Abstract: A disc cartridge that is adapted to receive a small-size optical disc and is compatible with a large-size disc cartridge. In the disc cartridge, first and second shutters open and close an opening. A connector links the first shutters to the second shutters as any one of the first and second shutters is driven.

Abstract: A disc cartridge adapter that is capable of driving a different size of disc cartridges with the same disc driver. In the adapter, a driving power transfer device absorbs a difference in a shutter travel range having a different size from each other to drive shutters of a small-scale disc cartridge. A body is provided with a receiving space for receiving the small-scale cartridge. Accordingly, the small-scale cartridge can be driven with a disc driver for driving a large-scale cartridge.

Abstract: An improved moving elements automatic transferring apparatus for a magnetic recording and reproducing apparatus capable of more simply transferring moving elements such as a reel table, a hub lock release member, and an identification board detection apparatus, which includes two reel tables; a reversibly rotatable pinion disposed between the reel tables; a plate having an elliptical slot, the plate being movable upwardly or downwardly; a rack engaged to a gear portion of the pinion, the rack being linearly movable, and having a hub lock release member disposed at one end thereof; two connection bars each having one end connected to the reel table, and the other end provided with a pin, respectively, of which one connection bar is hinged to the central portion of the pinion and the other connection bar is rigidly connected to the pinion; and spaced-apart two pins provided at ends of the connection bar and inserted into the slot.
