    摘要: A method for purifying exhaust gases from a diesel engine is provided. The method utilizes a flow through type honeycomb catalyst having parallel through-cells and (1) a cross-sectional area at the inlet part of an exhaust gas cut by a face vertical to the direction of the through-cells of 10 to 100 cm.sup.2, preferably 20 to 80 cm.sup.2, per liter of the displacement of the engine,(2) an hydraulic diameter of the through-cells of 1.00 to 2.00 mm, preferably 1.10 to 1.40 mm, and(3) the percentage of open frontal area at the inlet part of the exhaust gas of 40 to 95%, preferably 50 to 85%.

    摘要: A discharge lamp 50 comprises a luminous bulb 10 in which a luminous material 18 is encapsulated and a pair of electrodes 12 are arranged to be opposed to each other, and sealing parts (11a, 11b) that are formed at both ends of the luminous bulb 10 and in which metal foil structures 13 electrically connected to the pair of electrodes 12, respectively, are sealed. At least one of the metal foil structures 13 is composed of a first metal foil 13a, a second metal foil 13b and a metal bar 21 coupling both of them. At least one sealing part 11b of the sealing parts includes a cavity 20 around the position where in the sealing part the metal bar 21 is located, and at least a rare gas is encapsulated in the cavity 20.
