Abstract:
There is provided a more expedient and positive desiccating means for an organic EL device. The invention relates to an organic EL device comprising 1) a laminate consisting of an opposed pair of electrodes and an organic light-emitting layer sandwiched between the electrodes, 2) a gas-tight housing accommodating the laminate and shielding off the external atmosphere and 3) a desiccating means disposed in isolation from the laminate within the gas-tight housing, characterized in that a preformed moisture-absorbing artifact as the desiccating means is fixedly secured to at least one part of the gas-tight housing and further to a method of manufacturing the same device.
Abstract:
Two closed-loop coils are respectively set at the top or the bottom of a cathode ray tube. These two closed-loop coils serves in a pair as a cancel coil. Each closed-loop coil is positioned so as to make an interlinkage with the magnetic field leakage that escapes from the deflection yoke, a part of the closed-loop coil running almost in parallel to the top or bottom edge of an effective display region of a front panel.
Abstract:
A cathode ray tube has a phosphor screen and an electron gun including an indirectly heated cathode structure and a plurality of electrodes disposed downstream of the indirectly heated cathode structure for projecting an electron beam toward the phosphor screen, and a deflection yoke for scanning the electron beam on the phosphor screen. The indirectly heated cathode structure includes: a base metal having an electron emissive material coating on an outer top surface thereof; a metal sleeve having the base metal attached to an end of the metal sleeve; a heater housed partly within the metal sleeve which includes a major heating portion formed of a spirally wound heating wire and leg portions formed of heating wires wound spirally in a plurality of layers; an insulating film covering the major heating portion and a portion of each of the leg portions continuous with the major heating portion; and a black coating film covering a portion of the insulating film extending from the major heating portion toward each of the leg portions, the whole of the black coating film being housed within the metal sleeve.
Abstract:
To construct a CRT display device capable of effectively suppressing unwanted radiation of electromagnetic waves occurring as a result of horizontal deflection or vertical deflection. A correction lead (6) series-connected to horizontal deflection coils (1) is disposed at outer peripheral positions of the horizontal deflection coils (1) and between the horizontal deflection coils (1) and a faceplate of a CRT (4). With this arrangement, electromagnetic fields produced by the horizontal deflection coils are canceled out by electromagnetic fields produced by the correction lead (6), thereby suppressing unwanted radiation of electromagnetic waves at the deflection frequency and its harmonic components.
Abstract:
An arc lamp system comprises a power supply coupled to a xenon arc lamp through an interface constructed on a heavy printed circuit board. Such plugs directly into an igniter printed circuit board. In turn, a xenon arc lamp module with heatsinks plugs directly onto banana plugs bolted on the interface printed circuit board. Copper traces buried on inner layers of the interface printed circuit board are very wide and heavy, and kept as short as possible.
Abstract:
An inner shield assembly capable of maximizing an external magnetism shield effect. The inner shield assembly is provided at the rear side of a frame assembly for shielding external magnetism and includes a main body for shielding the inside of a funnel, a rectangular beam shield combined to the front of the main body and a front portion extending from the edge of the front of the beam shield around the outside of the shadow mask and the frame assembly. The material of the front portion has a maximum permeability of at least 3,000 and a coercivity of at most 1.25 Oe.
Abstract:
A high intensity discharge (HID) lamp includes a starting gas, a vaporizable fill, and only one electrode sealed within a light transmissive envelope. The one electrode produces a high intensity discharge during operation of the lamp and is connected to an inlead that extends outside the sealed envelope. A ground for electric field lines emanating from the electrode during operation of the lamp is outside the envelope. The ground may be a reflector for the lamp that has an electrically conductive surface. The high intensity discharge is initiated by applying high frequency power to the inlead.
Abstract:
A unique Hall-Current ion source apparatus is used for direct ion beam deposition of DLC coatings with hardness values greater than 10 GPa and at deposition rates greater than 10 Å per second. This ion source has a unique fluid-cooled anode with a shadowed gap through which ion sources feed gases are introduced while depositing gases are injected into the plasma beam. The shadowed gap provides a well maintained, electrically active area at the anode surface which stays relatively free of non-conductive deposits. The anode discharge region is insulatively sealed to prevent discharges from migrating into the interior of the ion source. A method is described in which a substrate is disposed within a vacuum chamber, coated with a coating of DLC or Si-DLC at a high deposition rate using a Hall-Current ion source operating on carbon-containing or carbon-containing and silicon-containing precursor gases, respectively. The method is particularly advantageous for producing thin, hard, wear resistant DLC and Si-DLC coatings for magnetic transducers and media used for magnetic data storage applications.
Abstract:
An apparatus is disclosed for use on a collimator of a radio-imaging device. The system includes a stack of plates provided with perforations, the thickness (d) of the plates being less than the diameter of the perforations in the internal entry face of the collimator. The thickness of the span between the perforations is made greater than the thickness of the plates.
Abstract:
A discharge lamp driver circuit is provided which features a field canceller. The driver circuit includes a power supply circuit which turns on and off a switching element to step up a dc voltage and provide it for turning on a discharge lamp. The power supply circuit includes an electrical path through which an interrupted current arising from the on-off operation of the switching element flows. The field canceller includes an electric line through which the interrupted current having passed through the electrical path flows in an opposite direction, thereby producing a field canceling a field caused by flow of the interrupted current through the electrical path.
