Abstract:
In a plasma display discharge tube in which an XY matrix electrode is constituted by arranging pluralities of stripe-like anodes (11) and stripe-like cathodes (9) at prescribed intervals so that they can cross each other and by using the space formed by each of intersection as a picture element, and which is made to display a picture by selectively exciting the picture elements in accordance with the picture, an AC type memory electrode (1) which is opposed to the XY matrix electrodes (9 and 11) and commonly used by all picture elements, and an AC type auxiliary electrode (5) which is brought into contact with the electrode (1) through an insulating layer and supplies electric power by utilizing the coupling capacitance formed between the electrodes (1 and 5) are provided so that memory discharge display can be made between the matrix electrodes (9 and 11) and the memory electrode (1). When the discharge tube is constituted in such a way as described above, the discharge tube can have a simplified electrode structure, can be manufactured through a reduced manufacturing process, can be driven by using the pulse memory type driving method which has been considered to be realized only in DC plasma display discharge tubes having high luminous efficacy and responsiveness, and can be provided with AC type electrodes having long service lives.
Abstract:
A method for fabricating microplasma discharge devices and arrays. The method employs techniques drawn from semiconductor device fabrication, such as chemical processing and photolithography, to produce arrays of devices inexpensively. An interdigitated electrode array is deposited on a first substrate. Cavities are formed in a second substrate by laser micromachining, etching, or by chemical (wet or dry) etching and the second substrate is overlaid on the electrode array. The inter-electrode spacing and electrode width are set so that each cavity has at least one pair of electrodes underneath it to excite a microplasma discharge in the cavity. The need to precisely register the two substrates is thus avoided.
Abstract:
Panneau comprenant une dalle avant (1) et une dalle arrière (4) ménageant entre elles une matrice bi-dimensionnelle de zones remplies de gaz de décharge, des moyens d'adressage (X, Y) pour activer sélectivement des zones de décharge présélectionnées en y déposant des charges électriques, et un dispositif de génération de rayonnement électromagnétique micro-onde (7) adapté pour appliquer au travers de la dalle arrière (4) à l'ensemble des zones de décharge du panneau, un rayonnement micro-onde d'intensité suffisante pour générer des décharges plasma uniquement dans les zones de décharge activées. On obtient un panneau simple à piloter et à haut rendement lumineux où les fonctions d'adressage et de maintien sont séparées.
Abstract:
An LER LUWPL source luminaire (1) having a magnetron (2) heat conductingly mounted below a finned heat dissipater (3) with a suspension eye (4). The magnetron is attached to a microwave transition (5) and a lucent crucible (6). An imperforate cover (8) extends down from the heat dissipater and is closed by a transparent screen (9), held to the cover by a moulding (10). The moulding supports a polished-sheet-metal reflector (11) extending back to the lucent crucible, with its reflective surfaces obliquely facing both the crucible and the screen for reflection of light from the crucible out of the luminaire via the screen. The moulding (10) is generally square shaped and the reflector comprises four triangular faces (12), pyramidally arranged, with a square base embodied by a rim (14) supported on the top of the screen (9) above the moulding (10). The faces converge to a virtual apex (15), on the central axis (16) of the lucent crucible. This axis is coincident with the pyramid's normal axis (17) from the apex to the centre of the base. The faces (12) are angled at 45° to the base. The apex is virtual in that the crucible and its backing piece (18) project through an aperture 19 in the reflector, above which the apex would exist if the aperture were not there

Abstract:
A method of fabricating micro-plasma discharge devices (90) and arrays. The method employs techniques drawn from semiconductor device fabrication, such as chemical processing and photolithography, to produce arrays of devices inexpensively. An interdigitated electrode array (16, 18) is deposited on a first substrate (14). Cavities are formed in a second substrate (34) by laser micromachining, etching or by chemical (wet or dry) etching and the second substrate (34) is overlaid on the electrode array. The inter-electrode spacing and electrode width are set so that each cavity has at least one pair of electrodes underneath it to excite a micro-plasma discharge in the cavity. The need to precisely register the two substrates are thus avoided.
