Title: Flyback transformer
Inventor: FUJIKI KATSUYUKI
IPC: H04N5/16
Filed: 1995-05-17
Abstract: PURPOSE: To suppress ripple on the focus voltage by providing a tertiary winding in a flyback transformer, generating a negative pulse in the tertiary winding and connecting the negative pulse voltage with a focus volume earth terminal. CONSTITUTION: The flyback transformer 31 comprises a primary winding 38, a secondary winding 39 and a tertiary winding 55 wound reversely to the primary winding 38 in order to generate a negative pulse voltage. Since a negative pulse voltage 53 generated in the tertiary winding 55 is connected with a focus volume earth terminal 53, a focus output voltage 52 equal to 25-35% of the difference between a high DC voltage 51 containing the ripple voltage 54 of final stage comprising several layers of secondary winding 39 and high voltage diode 41 and the negative pulse voltage 53 generated in the tertiary winding 55 is produced thus suppressing the ripple voltage 54 on the focus output voltage 52. Consequently, the ripple voltage can be suppressed without requiring any static focus capacitor.

Title: Plasma display device
Inventor: MASUDA SHINJI
IPC: G09F9/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To efficiently dissipate heat by forming a gas for heat dissipation by putting plural flexible wiring boards, which connect a plasma display panel and a control circuit part, partially one over the other. SOLUTION: The curved flexible wiring boards 16 and 17 are arrayed in opposite directions and arranged so that they partly overlap with each other. A nearly elliptic gap part 101 can be formed between the adjacent flexible wiring boards 16 and 17 of this configuration. Further, a slight gap can be formed at the overlap part 100. In this device, heat generated by the plasma display panel and the control circuit part is dissipated out of the housing by forcible suction by a fan or natural convection through the gap (gap part 101, gap formed by the overlap part 100, gap between arrays, etc.), of the flexible wiring board group. Consequently, gap area wider than the total area of the flexible wiring boards 16 and 17 is obtained to enable more efficient heat dissipation.
