Title: Method for refining high purity stainless steel
Inventor: KITAMURA SHINYA
IPC: C21C7/10
Filed: 1993-01-29
Abstract: PURPOSE:To stably and efficiently refine molten steel to ultra low carbon and nitrogen concns. by using a vacuum refining furnace and specifying the relation among vacuum degree and gas blowing position and flow rate and the interval between the tip surface of an immersion tube and the molten steel surface at the outside of the immersion tube. CONSTITUTION:Into the molten steel (c) containing >=5% Cr in a ladle (a), the straight barrel type immersion tube (b) is dipped and the pressure in the immersion tube (b) is reduced, and stirring gas is supplied from the bottom part of the ladle (a) to execute the refining. In this method, oxygen blowing is executed to 0.06-0.01% C content in the molten steel. Thereafter, oxygen supply is stopped and in the case of using P (Torr) for the vacuum degree, H (m) for bath depth at the gas blowing position and Q (NL/min ton) for the blowing gas flow rate, it is necessary to satisfy the relation (H/(5+P))XQ>=0.3. Chromium oxide-containing slag B on the vacuum surface produced during oxygen blow-refining is entrapped into the bath and also, the interval Z (m) between the tip surface of the immersion tube and the molten steel surface at the outside of the immersion tube and Q is made to be <=0.25 of Z/Q. Then, the entrapped slag C is flowed out (D) to the outside of the immersion tube and the decarburization at the bubble activating surface is promoted to the limitation.

Title: Separation prevented pipe fitting
Inventor: NAGAO SHIYOUZOU
IPC: F16L21/08
Filed: 1978-02-09
Abstract: PURPOSE: To obtain a secure preventive measure for pipe fitting separation by hindering slip-out of any projection through the diameter enlargement of a lock ring by such a construction that this lock ring is formed with a piece in circumferential view and every hook-shaped member of the lock ring is bolt-fixed with the aid of a coupling member.  
     CONSTITUTION: The separation of the socket 1 from the plug 2 is prevented  through engagement of a step 5a of the socket 1 with a projection 6 of the plug 2  with a lock ring 7 interposed. When any pull-out force is applied between the  socket 1 and the pulg 2, a diameter enalrgement force F is applied to the lock ring 7  due to the engagement with the projection 6 of plug 2. But the hook-shaped members 10a, 10b at the both ends of the lock ring 7 are coupled with the coupling members 11, so that undesirable enlargement of the lock ring 7 which might cause slip- out of the projection 6 of the plug 2, will never occur. Thus a secure prevention for  pipe fitting's separation is obtained.

Title: Corrosion resisting titanium alloy having superior bendability
Inventor: SUGIMOTO YOSHIHITO
IPC: C22C14/00
Filed: 1985-01-29
Abstract: PURPOSE:To obtain the titled inexpensive alloy having superior corrosion resistance and workability by providing a specific composition consisting of Ta, Zr, and Ti. CONSTITUTION:The corrosion resisting Ti alloy excelling in bendability consists of, by weight, 0.5-10% Ta, 1-7% Zr, and the balance Ti, and, though possessed of the corrosion resistance equal to or superior to the conventional Ti-Ta alloy, it has excellent workability and is far more inexpensive. The reasons for limiting the above alloy composition are as follows: when the amount of Ta is <0.5%, bendability as well as corrosion resistance-improving effect are reduced and when >10%, economization cannot be attained; when the amount of Zr is <1%, bendability-improving effect is not produced and when >7%, corrosion resistance is deteriorated. Further, O2, N2 and the like existing as inevitable impurities should be controlled each to about 0.2% or below.

Inventor: ITANI TAKAAKI
IPC: F16L47/02
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent foreign matter such as earth or slurry from adhering to a fusing part of a pipe with a joint by inserting a resin pipe into a pipe joint, sliding a surface protecting member from the fusing part of a pipe, and fusing the pipe joint with the pipe in the condition that the surface protecting member is placed at the inlet of an end of the pipe joint. SOLUTION: A pipe 1 is inserted in a joint 3 in the condition that a surface protecting member 21 is interposed on the inner surface of the inlet of the joint 3, and the pipe is held in this condition until fusion work is performed. Thus, even if earth or others cover a joint part, foreign matter such as earth does not adhere to a fusing part of the joint 3 with the pipe 1, and the surface of the fusing part of the joint 3 with the pipe 1 is held in a clean condition. After the preparation of the fusion work is finished, a heating wire 31 of an electric fusion joint 3 is conducted using a controller, and normal electric fusion connection is performed. Because such fusion is performed, in even fusion application work in underground drilling groove where earth easily adhere, earth does not adhere to the fusing part of the joint 3 with the pipe 1.
