Abstract: PURPOSE: A liquid crystal image displaying apparatus is provided to prevent light emitting efficiency from being prevented using a rare gas fluorescent lamp as the light source of a backlight unit. CONSTITUTION: A liquid crystal panel includes a pixel group which is capable of converting an optical shielding state and an optical transmitting state. A backlight unit is arranged on the rear side of the liquid crystal panel. Light source includes a pair of external electrodes(14) and three rear gas fluorescent lamps(1,2,3). Driving circuits(71, 72, 73) is in connection with the rear gas fluorescent lamps. Pixels display images using a field sequential mode.

Abstract: A ceramic lamp in which the hermetically sealing bodies of electrically conductive cermet are sealed to hermetically sealed tube portions of the lamp vessel with a sealing material is arranged and provided with material components designed to give the hermetically sealing portions a high reliability. In particular, a lamp of a translucent ceramic has a lamp vessel which has a bulb portion and hermetically sealed tube portions which are connected to the bulb portion, and electrically conductive supply components in the bulb portion which have base parts inserted into the hermetically sealed bodies of electrically conductive cermet, is improved by seal welding of the hermetically sealing bodies of electrically conductive cermet on the hermetically sealed tube portion with a sealing material so that a hermetically sealed arrangement is produced in which, in the border area between the sealing material and the hermetically sealing body, an intermediate layer is formed in which components of the electrically conductive cermet of the hermetically sealing body are intermixed with components of the sealing materials.

Abstract: A plugging body (6) for vessels which is made from a functionally gradient material composed of nonconductive and conductive components connected together so as to have a continuous or stepwise concentration gradient in the axial direction of a vessel to thereby make the material itself nonconductive on one side and conductive on the other side, plugs side tubes (3) joined to a luminous tube (2), and has a hole (10) into which an electrode core (7) is tightly shrinkage fitted. In this body, at least part of the surface of the electrode core (7) positioned in the hole (10) is coated with a thin film of a metal having a high melting point so as to prevent the craking of the plugging body (6) in the course of sintering the body (6).
