КОНСТРУКЦИЯ УЗЛА ДЛЯ ВАКУУМНЫХ ФОТОЭЛЕКТРОННЫХ ПРИБОРОВ

Полезная модель относится к устройствам крепления полупроводниковых структур к металлическим пластинам, которые применяются в электронике для создания прочных соединений, например, при креплении тонких матриц к металлическому основанию. Конструкция узла для вакуумного фотоэлектронного прибора представляет собой металлокерамический узел, к металлическому основанию которого крепится полупроводниковая пластина при помощи неорганической клеевой композиции на основе алюмофосфатной связки AlH(PO)2×3HO, в которой в качестве наполнителя используется алунд AlO в пропорции от 1:1 до 1:2 относительно АФС. В результате получается конструкция узла для вакуумного фотоэлектронного прибора на основе клеевой композиции, которая обеспечивает адгезионно и механически прочное соединение полупроводниковой пластины с металлическим основанием. За счет этого достигается прочность к воздействию механических ударов и синусоидальной вибрации. Так же состав клеевой композиции на основе АФС обеспечивает низкое газоотделение, что необходимо для поддержания уровня вакуума в полупроводниковых фоточувствительных приборах. Кроме того, благодаря тому, что данная клеевая композиция является изолятором, обеспечивается изоляция полупроводниковой пластины от металлического основания. При этом процесс изготовления конструкции узла для вакуумного фотоэлектронного прибора упрощается: т.к. отсутствует необходимость в дополнительных прижимных элементах.

Полезная модель относится к области электроники и вычислительной техники, конкретно к электрически перепрограммируемым запоминающим устройствам, и может быть использована при создании интегральных схем с наноразмерными элементами памяти. Элемент памяти на основе асимметричных мемристорных наноструктур состоит из изолирующей подложки, нижнего проводящего контакта, запоминающего слоя и верхнего проводящего контакта.

Microstructured, irregular surfaces pose special challenges but coatings of the invention can uniformly coat irregular and microstructured surfaces with one or more thin layers of phosphor. Preferred embodiment coatings are used in microcavity plasma devices and the substrate is, for example, a device electrode with a patterned and microstructured dielectric surface. A method for forming a thin encapsulated phosphor coating of the invention applies a uniform paste of metal or polymer layer to the substrate. In another embodiment, a low temperature melting point metal is deposited on the substrate. Polymer particles are deposited on a metal layer, or a mixture of a phosphor particles and a solvent are deposited onto the uniform glass, metal or polymer layer. Sequential soft and hard baking with temperatures controlled to drive off the solvent will then soften or melt the lowest melting point constituents of the glass, metal or polymer layer, partially or fully embed the phosphor particles into glass, polymer, or metal layers, which partially or fully encapsulate the phosphor particles and/or serve to anchor the particles to a surface.

A device for lighting a room is described. The device has an envelope with a transparent face, the face having an interior surface coated with a cathodoluminescent screen and a thin, reflective, conductive, anode layer. There is a broad-beam electron gun mounted directly to feedthroughs in a base of the envelope with a heated, button-on-hairpin, cathode for emitting electrons in a broad beam towards the anode, and a power supply mounted on the feedthroughs at the base of the envelope that drives the cathode to a multi-kilovolt negative voltage. A two-prong snubber serves as an anode contact to permit the power supply to drive the anode to a voltage near ground. A method of manufacture of the anode uses a single step deposition and lacquering process followed by a metallization using a conical-spiral tungsten filament coated with aluminum by a thermal spray coating process.

In an accelerating tube which uses a conductive insulator, there is a possibility that the dopant concentration on a surface of the conductive insulator becomes non-uniform so that the surface resistance of the conductive insulator becomes non-uniform. Accordingly, a circumferential groove is formed on the inner surface of the conductive insulator accelerating tube in plural stages, and metal is metalized along inner portions of the grooves. When the resistance of a specific portion on the surface of the accelerating tube differs from the resistance of an area around the specific portion, the potential of the metalized region on the inner surface of the accelerating tube becomes a fixed value and hence, the potential distribution on the inner surface of the accelerating tube in the vertical direction can be maintained substantially equal without regard to the circumferential direction. 1.

When using micro-resonant structures, a resonant structure may be turned on or off (e.g., when a display element is turned on or off in response to a changing image or when a communications switch is turned on or off to send data different data bits). Rather than turning the charged particle beam on and off, the beam may be moved to a position that does not excite the resonant structure, thereby turning off the resonant structure without having to turn off the charged particle beam. In one such embodiment, at least one deflector is placed between a source of charged particles and the resonant structure(s) to be excited. When the resonant structure is to be turned on (i.e., excited), the at least one deflector allows the beam to pass by undeflected. When the resonant structure is to be turned off, the at least one deflector deflects the beam away from the resonant structure by an amount sufficient to prevent the resonant structure from becoming excited. 1.

The present invention reliably and sufficiently corrects a voltage variation in data signal lines in a display device resulting when sampling analog video signals, while suppressing increase in layout area. In a data signal line drive circuit of an active matrix liquid crystal display device, a video signal Svi is sampled by an Nch transistor (SWk) which has a parasitic capacitance (Cgd) that causes a voltage drop in a data signal line SL(i−1)+k (i=1 through n; k=1, 2, 3). To correct this, an inversion delayer () makes logical inversion of the transistor (SWk)'s control signal Sck and delays the inverted signal for a predetermined time to generate an inversion delayed signal Srdk, and applies this inversion delayed signal Srd to the data signal line (i−1)+k via a correction capacitance element (Cc). The inversion delayer () makes the inversion delayed signal Srdk start its change from an L level voltage to a H level voltage after the Nch transistor (SWk) has assumed an OFF state. 1. A data signal line drive circuit provided with analog switches for applying analog video signals to a plurality of data signal lines respectively and causing the plurality of data signal lines to hold the analog video signals respectively , the plurality of data signal lines being connected to a plurality of pixel formation portions for formation of an image to be displayed , the circuit comprising:an analog switch provided for each of the plurality of data signal lines and including a field effect transistor having: a first conduction terminal for receiving an analog video signal to be applied to one of the pixel formation portions connected to a corresponding one of the data signal lines; a second conduction terminal connected to the corresponding data signal line; and a control terminal for receiving a control signal for switching between an ON state and an OFF state;a correction capacitance element including a first terminal connected to the corresponding data signal line; andan ...
