Abstract: There are provided a distributed survey system for obtaining underground electrical characteristics and a distributed survey method using the same which can be flexibly compatible with the survey purposes, the geographical conditions of the survey region, etc. and which can obtain the underground electrical characteristics more efficiently in a shorter time. In the invention, survey units (1, 2, 3, . . . (N?1), N) are distributed across a region in which underground electrical characteristics are to be obtained.

Abstract: The present invention relates to an AC drive surface discharge type plasma display panel having an isosceles delta array type pixel. The background art has a problem of being apt to cause a wrong writing discharge and having a narrow writing voltage margin. Then, in the present invention, transparent electrodes for X electrode (T3, T4) in first and second pair subpixel regions (PSPR1, PSPR2) of an isosceles delta array type pixel (P1) are provided at portions farther away from a first write electrode (Wj(B)) in an isolated subpixel region (ISPR). Specifically, a central axis of the third transparent electrode (T3) along a vertical direction (v) is positioned closer to an extending portion (WAE) of a second write electrode (Wj(A)) from a vertical direction central axis of the first pair subpixel region (PSPR1).

Abstract: Components of an arrangement interval in first and second directions (v, h) between first to third subpixels (C1, C2, C3) in a pixel (PX) satisfy the following expressions: pv1=pv2=pv/2; pv3=0; and ph1=ph2<ph/3. Components of the arrangement interval in the first and second directions (v, h) between two pixels (PX) adjacent to each other in the second direction (h) satisfy the following expressions: pv4=pv/2 (=p/2); pv5=0; and ph4>ph/3. Pixels (PX) adjacent to each other in the first direction (v) have the same arrangement of the first to third subpixels (C1, C2, C3).
