Abstract:
The invention provides a method of forming a resistance film with even thickness and at high speed even in a substrate having micro depressions and projections in its surface. A fine particle dispersion solution is prepared by adding a solution which decreases the absolute value of a ξ potential at the fine particles and a solution which decreases dispersion stability of the fine particles into a solution in which metal oxide fine particles are stably dispersed, a substrate having an insulating surface is immersed in the fine particle dispersion solution to deposit a fine particle aggregation film, and then a resistance film is obtained by performing heat treatment.

A recording method for an optical medium having a disk-like substrate with a spiral or concentric-shaped groove structure along a track formed on the substrate. The groove structure is wobbled in a radial direction of the medium and the track is divided into a plurality of units in the track direction by at least one radial boundary line formed by a dropout portion. Identification information is disposed in the track at a head of each recording unit at the dropout portion and the medium is divided into a plurality of zones in a radial direction with a length of a circular arc being substantially the same between the zones in a circumferential direction. At least two adjacent units in the radial direction of the medium comprise one zone. The method includes providing the optical medium, and recording information on the optical medium by irradiating an optical spot thereon.

Abstract:
A plasma display device comprises an area ratio detection means for detecting the area ratio of pixels having any luminance higher than a predetermined value in a display region; and a sustain frequency adjust means for adjusting, in accordance with the detected area ratio, the frequency or number of sustain pulses inputted to paired sustain electrodes in such a manner that the luminance in the display region satisfies a predetermined reference value. In this device, the frequency or number of the sustain pulses inputted to the paired sustain electrodes is adjusted in accordance with the detected area ratio, so that the luminance is always corrected to the reference value to thereby achieve proper expression of preset gradations.
