Disclosed herein is a plasma display panel in which afterimage is improved. The plasma display panel according to the present invention includes a panel unit having an upper plate and a lower plate, a frame that supports circuitry, and a conductive material formed between the panel unit and the frame. As such, a conductive material is formed on a bottom surface of a lower plate of a panel. Thus, charges introduced into the lower plate are properly controlled to improve the waveform stability of the panel. Also, a charge characteristic is improved to implement a stable operation. Accordingly, an afterimage time can be reduced. Further, a sheet of a low hardness and light weight is used. It is thus possible to absorb shock and noise of a PDP, accomplish light weight of the PDP and reduce the materials of the sheet.

A race track lighting system comprising a plurality of fixtures mounted in spaced relationship to one another on the infield side of the track and projecting light outwardly and downwardly onto the track surface from relatively low poles. Each fixture is asymmetric so as to provide a strong cut-off preventing light from being projected, into the eyes of oncoming driver, but a divergent pattern in the direction of traffic flow so as to blend the light from one fixture with the light from an adjacent fixture for the purpose of promoting uniformity in the lighting intensity. The lamp is offset in the fixture and a blocker strip is placed in from of the lamp to prevent direct, uncontrolled light, from reaching the track.

The invention discloses a haze-preventing shutter window which comprises a window body, a shutter, water curtain nozzles, a baffle plate, a fish tank and a flower bed, wherein a plurality of water curtain nozzles are uniformly arranged on a water ejection pipe on the upper side of the window body; water flow ejected from the water curtain nozzles is fan-shaped and is combined into pieces; the water ejection pipe is arranged between the shutter and the baffle plate.
