    Abstract: It is provided a ceramic vessel 1A for a high pressure discharge lamp and for filling an ionizable luminous substance and a starter gas in the inner space of the vessel. The discharge vessel 1A has a tubular central luminous portion 2A, and a pair of tubular end portions 3 protruding from both ends of said central luminous portion, respectively. Each of the end portions 3 has a maximum wall thickness "l" of 0.5 times or larger and 0.9 times or smaller of the wall thickness "t" of the central luminous portion 2A. A ceramic discharge vessel is thereby provided enabling for improving the luminous efficiency of the high pressure discharge lamp.

    Abstract: A process to produce a ceramic tube for a metallic halide lamp, comprising the steps of forming an integrally molded body (1) composed of an electrode member-inserting portion (1a) and an annular portion (1b) located around an outer periphery of the electrode member-inserting portion, inserting the annular portion of the integrally molded body into an open end portion of a molded cylindrical tubular body (3) in a state that each of the integrally molded body and the molded tubular body is used as molded or after being calcined, thereby forming an assembled body, and firing the assembled body, thereby forming an integrally fired body composed of the electrode member-inserting portion and the annular portion. The annular portion and the tubular body are sintered to each other by firing in a state that radial press fitting forces act between the annular portion and the tubular body.

    Abstract: Ein Verbindungssubstrat umfasst ein Keramiksubstrat mit einem Durchgangsloch darin und einen Durchgangsleiter 11, der in dem Durchgangsloch bereitgestellt ist und eine erste Hauptoberfläche 11a und eine zweite Hauptoberfläche 11b umfasst. Der Durchgangsleiter 11 umfasst einen porösen Metallkörper 20, der erste offene Poren 16A, 16D, die mit der ersten Hauptoberfläche 11a in Verbindung stehen, und zweite offene Poren 16B, die mit der zweiten Hauptoberfläche 11b in Verbindung stehen, umfasst, erste Glasphasen 17, 19, die jeweils in den ersten offenen Poren 16A, 16D bereitgestellt sind, zweite Glasphasen 17B, die jeweils in den zweiten offenen Poren 16B bereitgestellt sind, erste Räume 30, die jeweils in den ersten offenen Poren bereitgestellt sind, und zweite Räume 32, die jeweils in den zweiten offenen Poren 16B bereitgestellt sind. Die ersten Räume 30 sind geschlossene Räume, die nicht mit der ersten Hauptoberfläche in Verbindung stehen. Die zweiten Räume 32 sind offene Räume, die mit der zweiten Hauptoberfläche 11b in Verbindung stehen.
