Abstract:
Effective and uniform driving of a large organic EL display panel is formed using a plurality of stripes for each of first electrodes and also for each of second electrodes. These stripes are electrically isolated from each other, which enables each group of pixels defined by a set of orthogonal stripes to be driven separately from the remaining groups of pixels. Efficient fabrication methods devised to construct the display panel are cost effective and suitable for mass production.
Abstract:
A vacuum envelope of a cathode ray tube includes a rectangular panel having an inner surface where a substantially rectangular phosphor screen is formed, a neck in which an electron gun is provided, and a funnel connected between the panel and the neck. The funnel has a first portion having a large diameter and positioned on the phosphor screen side, and a substantially truncated quadrangular pyramid-like second portion positioned on the neck side. From the second portion to the neck, a deflection yoke is mounted on the outer surface of the funnel. Where the vacuum envelope is cut along a plane including a tube axis, the shapes of the cross-sections of the first and second portions have an inflection point at the boundary between the first and second portions. The end of the deflection yoke on the phosphor screen side is positioned near the inflection point.
Abstract:
Pad portions are respectively integrally protruded to be formed on an outer surface of a substantially funnel-shaped sidewall portion of the glass funnel for projection. A ridgeline for a reference end face formed on the pad portion comprises a first curved portion to form a top portion and second curved portions to form rising portions. The first curved portion and the second curved portions are smoothly continuous to each other without bending portions. The second curved portion is smoothly continuous to the outer face of the sidewall portion without bending portions.

Abstract:
A color cathode ray tube includes an evacuated envelope having a generally rectangular panel portion, a narrow neck portion having a circular cross-section and a funnel portion tapering down from a panel-portion side thereof toward a neck-portion side thereof for connecting the panel portion and the neck portion, a three-color phosphor screen formed on an inner surface of the panel portion, an electron gun housed in the neck portion, and an internal conductive film extending from an inner wall of the neck portion to an inner wall of the funnel portion. The funnel portion is provided with a yoke-mounting portion of generally truncated quadrilateral-pyramidal shape for mounting a beam deflection yoke therearound on the neck-portion side of the funnel portion. The internal conductive film is formed of a first part and a second part, the first part is formed of graphite, metallic oxide and potassium silicate, and the second part is formed of graphite and potassium silicate. The first part extends from the neck portion in the vicinity of a forward end of the electron gun to a position in the yoke-mounting portion spaced a distance in a range of 60 mm to 150 mm from a splice line between the neck portion and the funnel portion, and the second part overlaps with the first part at opposing ends thereof and extends to a vicinity of a seal line between the funnel portion and the panel portion.

A cathode ray tube having a reduced variation in convergence drift. An inner graphite layer coats the inner surface of a funnel, and a metal coating layer is electrically connected with the inner graphite layer on the inner surface of the neck portion. The metal coating layer does not extend to a position directly beside the focusing electrode most remote from the cathode of the electron gun of the cathode ray tube, and has a surface resistivity of 107&OHgr;/□ or less.
Abstract:
An arrangement and corresponding method are provided for coupling radiation, preferably laser radiation, into a scanning head with a scanning unit in at least two dimensions. The radiation is focussed on an object via a microscope objective via at least one light-conducting fiber which is coupled with the scanning head. A collimator is arranged downstream of the fiber end at the scanning head for collimating the radiation exiting in a divergent manner at the fiber end.
Abstract:
A composite material suitable for labeling a substrate. The composite material, which is preferably a ceramic composite, comprises a fired ceramic body and a layer thereon. The fired ceramic body includes a base layer that comprising a glassy phase and a refractory phase, the glassy phase being capable of wetting a substrate at an application temperature. There is sufficient color contrast between the top layer and the fired ceramic body such that a code pattern (e.g., a bar code) present (or formed) is optically discernible. Methods of making and using the same are also taught.
