A plasma display panel (PDP) having improved luminous efficiency may be constructed with an upper substrate, a lower substrate disposed parallel to the upper substrate, and a plurality of upper barrier ribs formed of a dielectric disposed between the upper substrate and the lower substrate. The upper barrier ribs, together with the upper substrate and the lower substrate, define discharge cells. A plurality of upper discharge electrodes are disposed to surround the discharge cell are embedded in the upper barrier ribs. A plurality of lower discharge electrodes that are spaced-apart from the upper discharge electrodes are embedded in the upper barrier ribs to surround the discharge cell. A plurality of lower barrier ribs are disposed between the upper barrier ribs and the lower substrate. A plurality of central barrier ribs may be positioned inside the discharge cells, a plurality of fluorescent layers are formed between side surfaces of the lower barrier ribs and side surfaces of the central barrier ribs, and a discharge gas is used to fill the discharge cells.

A plasma display panel includes a red phosphor layer, a green phosphor layer, and a blue phosphor layer. The thickness of the phosphor layer is satisfied by the following condition: when D is (S−2L)/S, D≧0.64, S being a distance between barrier ribs at half the height of the barrier ribs, and L being a side thickness of the phosphor layer coated on the barrier ribs at half the height thereof.

The present invention relates to a description and implementation method of ThreadBean in an Enterprise Java Bean (EJB) container. In the description and implementation method of ThreadBean in an EJB (Enterprise Java Bean) container, the ThreadBean is defined using EJB to which an independent thread is allocated such that looping is performed while a message entering a determined message target is processed or a business logic periodically driven to perform a specific work is processed.
摘要:
A compensation pendulous accelerometer comprises a body in which a pendulous unit is positioned that is made as a unitary plate of a silicon monocrystal and comprises a movable vane on a flexible suspension and a support frame with protrusions. Two magnetic systems are secured on opposite sides of the movable vane and two coils of a torquer are positioned in a clearance of a corresponding core and are secured on a corresponding side of the movable vane. The flexible suspension includes flexible members arranged at an angle of 90 degrees relative to one another, symmetrically relative to an axis of symmetry of the pendulous unit. When the accelerometer is accelerated, the movable vane deflects in the opposite direction of the acceleration, and a current in the coils returns the movable vane to its initial position. A measured amount of current through coils is used to determine the acceleration.

A negative capacitance logic device includes a first field effect transistor (FET) and a second FET. The first FET is coupled between a power supply voltage and an output node, and the first FET includes a ferroelectric having a negative capacitance. The second FET is coupled between the output node and a ground voltage, and the second FET includes a ferroelectric having a negative capacitance. The negative capacitance logic differentiates an input voltage applied to an input node to provide an output voltage at the output node.
