摘要： A basic structure of a screw joint coupling for oil pipes according to the invention is that a main sealing portion is constructed with a sealing portion formed axially in convex at an end of a male screw, and with a sealing portion formed in taper at an inner side of a female screw, and that the male screw and the female screw are butted at an end point of the former and an end part of a stopper formed at an inner side of the latter. The main sealing portion has a shrinkage allowance .DELTA.D of the seal part, which is regulated in size in a relation between a shrinkage allowance .DELTA.d of the screw and a pressure P of the sealing part. In addition, specific values are selected as to the load flank angle, the radius of curvature in convex of the sealing portion of the male screw, and the tapering angle of the sealing portion of the female screw.

摘要： The present invention is to obtain a glass bulb of reduced weight, and high safeness and reliability by ion exchanging which assures a compressive stress layer having an effective thickness even to a large tensile vacuum stress. For this purpose, a region in an outer surface of a body portion 4 of the glass funnel, the region having a small mechanical strength and producing the maximum tensile vacuum stress thereby causing breakage easily, is partly strengthened by ion exchanging method according to an electric field assisting method and an ion exchanging method using paste in combination, whereby a portion 9 strengthened by ion exchanging method is provided in that region wherein the concentration of doped ions in a strengthened compressive stress layer is distributed according to a substantially step function in a direction from the surface of the glass toward the inside of it.
