Abstract:
A display screen of a color display is disclosed (see FIG. 1). The display screen includes a glass plate having an array of three different color-emitting phosphors thereon. A graphite-based matrix is placed in the interstitial regions between each of the three different color-emitting phosphors. The graphite-based matrix is formed from an aqueous composition including graphite, potassium silicate and sodium silicate.
Abstract:
Performance of an electrohydrodynamic fluid accelerator device may be improved and adverse events such as sparking or arcing may be reduced based, amongst other things, on electrode geometries and/or positional interrelationships of the electrodes. For example, in a class of EHD devices that employ a longitudinally elongated corona discharge electrode (often, but not necessarily, a wire), a plurality of generally planar, collector electrodes may be positioned so as to present respective leading surfaces toward the corona discharge electrode. The generally planar collector electrodes may be oriented so that their major surfaces are generally orthogonal to the longitudinal extent of the corona discharge electrode. In such EHD devices, a high intensity electric field can be established in the “gap” between the corona discharge electrode and leading surfaces of the collector electrodes.

Abstract:
A mercury vapor lamp having a light transmissive envelope defining an arcuate capillary plasma cavity. A mounting base secured to one end of the envelope has a configuration which is geometrically unique with respect to the position and spatial orientation of the plasma cavity. A mounting block and clamping arrangement have a configuration complementary to that of the lamp base so as to receive and releasably secure the lamp base and, therefore, the plasma cavity in a fixed predetermined position and orientation relative to its operating environment. The lamp is energized by means of an electrical potentional applied to electrodes in the plasma cavity or by reactance coupling an r-f power source to the cavity.
Abstract:
A method of evaluating a power storage device includes at least [a] to [f] below. [a] A power storage device is prepared. [b] A charge level of the power storage device is adjusted to produce a first potential difference between a positive electrode and a negative electrode. [c] The positive electrode or the negative electrode is selected as a reference electrode. [d] After the charge level is adjusted, an operation to insert a conductive rod-shaped member into a stack portion along a direction of stack of the positive electrode and the negative electrode is performed while a second potential difference between the reference electrode and the rod-shaped member is measured. [e] The rod-shaped member is stopped. [f] The power storage device is evaluated based on a state of the power storage device after the rod-shaped member is stopped.
