Abstract: Disclosed is an automobile underbody structure, wherein a pair of laterally-spaced floor frames 10 are disposed to extend longitudinally in such a manner as to interpose a tunnel region 6 of a front floor portion 2 therebetween and joined to a bottom surface of the front floor portion 2, and a cross member 15, 16 is disposed to extend laterally so as to connect each side-sill 7 and the tunnel region 6 and joined to a top surface of the front floor portion 2. Each of the floor frames 10 is gradually inclined laterally inward toward the rear end thereof so as to be obliquely disposed relative to the cross member 15, 16 in top plan view. A rearward displacement of the floor frames 10 during a head-on collision exerts a compressive force on a region of the cross member 15, 16 located on the laterally outward side relative to each of the floor frames 10, and a tensile force on a region of the cross member 15, 16 located on the laterally inward side relative to each of the floor frames 10.

Abstract: The reliability of the airtight sealed section is improved by providing a metallic or ceramic insertion member at a portion positioned between an electricity introducing member and a narrow tube in the airtight sealed section. The difference between the inner diameter of the narrow tube and the outer diameter of the insertion member is made 0.02 to 0.6 mm. The electricity introducing member is constructed by a halogen-resistant first member and a second member whose coefficient of linear expansion is similar to that of the narrow tube, and the junction of the first member and second member is covered with a halogen-resistant glass sealant. The difference between the insertion length of the second member into the narrow tube and the flow-in length of the glass sealant into the narrow tube is made 1 mm or more.

Abstract: A discharge lamp comprises an arc tube 6 made of a translucent ceramic dosed with a metallic halide. The discharge is conducted between electrodes 20 disposed in the arc tube 6. The arc tube 6 comprises a main tube body 11 having a large diameter portion 11A and a small diameter portion 11C, and a narrow tube 12 airtightly fixed to the small diameter portion 11C while penetrating the small diameter portion 11C. In the discharge lamp, supposing that L (mm) is the length of a protrusion from the main tube body of the narrow tube portion 12 and P (W) is the rated power of the discharge lamp, L and P satisfy the relationship (P+268.75)/31.25≦L≦(P+456.25)/31.25 and 200≦P≦450.

Abstract: An arc tube 6 of discharge lamp comprises a main tube body 11 of translucent ceramic sealed with a terminal plate 13 at both ends thereof. The main tube body 11 comprises integrally a large diameter portion 11A, a tapered portion 11B which is disposed at both sides of the large diameter portion 11A and has a smaller diameter toward the forward end thereof, and a small diameter portion 11C which is connected to the forward end of the tapered portion 11B. In this arrangement, the discharge lamp can be produced more easily than the conventional structure having a narrow portion integrally formed at both ends of a ceramic tube body, making it possible to drastically reduce cost. Further, since a low temperature zone can be only with difficulty formed inside the arc tube during discharge, the luminous efficiency can be raised.
