Abstract: A discharge panel capable of high-quality display by preventing erroneous discharge between adjacent lines in a sustaining electrode or the like. A sectional shape in a direction orthogonal to the longitudinal directions of both a first display electrode (101a) and a second display electrode (101b) has a stepped shape, a film thickness of a discharge gap (Gap1) side portion is greater than that on a non-discharge gap side, the film thickness of the respective steps being specified as L1, L2, L3 (L1>L2>L3). Accordingly, a discharge start voltage on the discharge gap side is lower than that on the non-discharge gap side even when the discharge gap and the non-discharge gap have the same width geometrically, thereby reducing erroneous discharge between adjacent cells positioned on an adjacent lines.

Abstract: Background plasma electrons in a laser wake field are trapped and accelerated using a sharp downward density transition. A short and intense laser pulse travels through low density plasma with a sharp downward density transition. The density transition scale length is much smaller than the wavelength of a laser wake wave. As the laser wake wave passes the density transition, its wavelength increases suddenly so that some background plasma electrons are self-injected into the acceleration phase of the wake field and trapped and accelerated by the strong laser wake field.

Abstract: A low-pressure discharge lamp is described having a base housing (10), a discharge vessel (2), whose end sections are fixed to an end section of the base housing, and a contact-making system for making electrical contact with the lamp, which is located on the end section of the base housing (10) which is remote from the discharge vessel, a conductive section (5) being provided, which is electrically connected to the contact-making system and is arranged adjacent to the discharge vessel (2) in the base housing (10) in such a way that an electrical short circuit is formed around the discharge vessel (2). This makes it possible to reduce the starting voltage of the lamp. As an alternative, or in addition, to this, the cross section of the web attachments is increased, which also increases the rate of the luminous-flux run-up.

Abstract: Methods and apparatuses for fabricating an electroluminescent display structure. A method including coupling a frontplane to a backplane wherein a frontplane top surface laminates to a backplane top surface. The frontplane and the backplane are fabricated separately. A first electrode layer which is transparent is disposed over the frontplane. A display medium which produces electro-optical effects upon a voltage application is disposed over the first electrode. A second electrode layer which is pattered is disposed over the display medium. The second electrode layer includes a plurality of connecting regions. The backplane is electrically active to provide driving signals for the display medium wherein the backplane includes a plurality of output pads to match the plurality of connecting regions.

Abstract: The invention provides a joined body of a first member made of a metal and a second member made of a ceramic or a cermet. The joined body comprises a joining portion interposed between the first member and the second member for joining the first and second members. The joining portion comprises main phase contacting the first member and an intermediate ceramic layer existing between the second member and the main phase and contacting the second member. The main phase is composed of a porous bone structure, having open pores and is made of a sintered product of metal powder, and a ceramic phase impregnated into the open pores in the porous bone structure. The joined structure has resistance to fatigue and fracture, even when the structure is subjected to repeated thermal cycles between a high temperature, for example 1000° C. or higher, and room temperature.

Abstract: An electron tube 10 mainly includes a sleeve 12, an input plate 14 having a photocathode surface 18, a stem 16 and a CCD 20. A vacuum is provided in an interior of the electron tube 10. The CCD 20 is fixed onto the stem such that a rear surface B faces the photocathode surface 18. In the CCD 20, on a single conductive type semiconductor substrate 64, a buried layer 66, a barrier region 68, a SiO2 layer 70, a storage electrode layer 72, a transmission electrode layer 74, and a barrier electrode layer 76 are formed at their predetermined positions. A PSG film 78 is formed at an entire front surface A over these layers to flatten the surface of the CCD 20. Further, SiN film 106 mainly composed of SiN is formed above the PSG film over the entire front surface A.

Abstract: In a spark plug of the invention, as the top end edge of a terminal 13 is located within a middle trunk portion 2g of the insulator 2 with a longer reach of the screw portion 7, it acts as a support against fracture, more likely causing the problem of strength. Thus, the wall thickness of the middle trunk portion 2g at a position corresponding to the top end edge of the terminal 13 is sufficiently secured to be 0.42 or larger, based on the value of (D−d)/D, whereby it is possible to prevent the inconvenience such as fracture of the insulator, particularly, the middle trunk portion 2g from occurring owing to some strong force of bending, impact or torque applied on the insulator 2, when the spark plug is attached.

Abstract: An incandescent light, which uses a rotating, liquefied filament. The rotating filament consists of a thin layer of filament metal deposited on the interior convex surface of a refractory filament mount, which is inside the torus. The filament device is designed to rotate at a speed sufficient to prevent the metal from boiling off from, or breaking away from, the refractory surface of the filament mount as it rotates. The rotational speed of the torus will create a centrifugal force greater than the thermal forces, which would otherwise destroy the molecular integrity of the filament metal. The temperature of the deposited filament metal will exceed its normal melting point as it rotates. As it becomes hotter it will luminesce more in exponential proportion to the current applied to the rotating torus filament assembly.
