The USB apparatus includes a Printed Circuit Board (PCB) including a circuit for communicating data with an external device according to a USB communication standard, a connector for connecting to a USB terminal of the external device, and a noise reduction circuit connected between an output terminal of the PCB and the connector for reducing noise of a data signal. The noise reduction circuit includes a common-mode filter for removing harmonic components generated between a ‘+’ data signal and a ‘−’ data signal and passing the ‘+’ data signal and the ‘−’ data signal, which operate in a differential mode.
Abstract:
A roll blind includes: a safety cord connected to and wound around a chain pulley adapted to rotate the winding rod, the safety cord having a separated lower end so that one side defines a lowering cord for pulling down the blind material and the other side defines a raising cord for rolling up the blind material; a bidirectional clutch unit adapted to raise/lower the blind material, the bidirectional clutch unit being positioned between the chain pulley and a driving shaft of the winding rod, the bidirectional clutch unit having bidirectional protrusions formed on an inner peripheral surface of the chain pulley at an identical interval in a circumferential direction so that, when the lowering or raising cord is pulled, the winding rod rotates together with the chain pulley, the bidirectional clutch unit having a number of rollers positioned between respective bidirectional protrusions.
Abstract:
The present invention relates to a bacteriophage PA1Φ belonging to family Siphoviridae, characterized that it is capable of killing one or more bacteria strains selected from a group comprising Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus homonis, Shigella sonnei, Listeria monocytogenes and Streptococcus pneumonia, and contains a full-length genome of SEQ ID NO: 1.According to the present invention, the bacteriophage PA1Φ can be used to kill said bacteria and reduce the same effectively. Also, it can be used to remove biofilms generated by said bacteria. Especially, this bacteriophage is applicable for medical industry, food industry, biotechnology and the like, because it is a sort of virus that kills host bacteria without any adverse effect on human, animals and so on. In addition, this bacteriophage can kill noxious bacteria on target sites or target supports without any problem related with resistance development of bacteria.

Abstract:
A plasma display panel (PDP) comprises: a front substrate and a rear substrate which face each other; and a barrier wall which is interposed between the front substrate and the rear substrate, which includes base portions arranged on either side of a main discharge space, and protruding portions protruding on the base portions, respectively, and which defines stepped spaces on either side of the main discharge space. The stepped spaces are formed according to stepped surfaces formed by the base portions and the protruding portions. The PDP further comprises a pair of a scan electrode and a sustain electrode which generate a mutual discharge through the main discharge space. A channel space is defined by outer walls of the protruding portions on either side of the main discharge space, and an external light absorbing layer covers the channel space.

Abstract:
A dual roll blind system is able to adjust a light shading rate or extent and comprises a winding roll which includes a roll casing rotatably supported between both side plates of a ceiling bracket; a driving winding roll which includes a moving member disposed between both side plates in parallel with the winding roll and is thread-engaged with a screw shaft rotating by means of a blind winding device of one side, a straight moving member which is provided for left and right straight movements by restricting the rotation of the moving member, and a roll casing engaged with the moving member and the straight moving member; a first blind material of which upper end is fixed at the winding roll and in which a light transmission part and a light non-transmission part having constant widths are alternately formed in a width wise direction; a second blind material of which upper end is fixed at the driving winding roll and which has a light transmission part and a light non-transmission part corresponding to the first blind material and is movable left and right; and a counterweight bar which fixes a lower end of the first blind material with a lower end of the second blind material being slidably inserted into the counterweight bar in a parallel direction.
Abstract:
A plasma display panel is disclosed. The plasma display panel has discharge cells which each have a range of widths between the first substrate and the second substrate. In addition, the discharge spaces are separated by non-discharge spaces having heights substantially the same as the heights of the discharge spaces.
Abstract:
A plasma display panel (PDP) includes: a front substrate facing a rear substrate; first and second discharge enhancement layers disposed between the front and rear substrates and arranged on both sides of a main discharge space; first and second barrier ribs respectively formed on the first and second discharge enhancement layers and defining first and second asymmetric stepped spaces along with the first and second discharge enhancement layers; a scan electrode and a common electrode inducing a mutual discharge in the main discharge space; an address electrode generating an address discharge along with the scan electrode and extending in a direction to intersect the scan electrode; a phosphor layer formed in at least the main discharge space; and a discharge gas filled in the main discharge space and the first and second stepped spaces.
