Title: Packing assembling structure
Inventor: MARUYAMA MIYUKI
IPC: B65D53/02
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To attain easy removal of a packing without spoiling a sealing performance of the packing in a packing assembling structure wherein the packing is placed on a groove part. SOLUTION: A notch 7a notched from an engagement surface is formed on a side surface of a groove part 6, and a gripping part 8a projecting from the notch 7a to a side direction of the groove part 6 is formed on a packing 8. The packing 8 can be thereby easily removed from the groove part 6 with gripping the gripping part 8a. Moreover, the gripping part 8a is not projected above a sealing surface contacting with the engagement surface since the gripping part 8a is projected from the notch 7a to the side direction of the groove part 6, and the engagement surface 1a and the like can be thereby engaged without spoiling a sealing performance.  The packing 8 becomes easy to remove from the groove part 6 since the engagement surface 1a is a rectangular shape and the groove part 6 is formed along the engagement surface 1a to be a rectangular shape with the gripping part 8a positioned at an angle part 7 of the rectangular shape, and a work for removing the packing 8 can become easier.

IPC: G02B6/44
Filed: 1995-05-17
Abstract: PURPOSE: To relieve the elongation and distortion of bundled plural optical fibers and to ameliorate their bending characteristics by housing units which are formed by twisting these optical fibers on the outer peripheries of cords having a cushion property and are provided with extra lengths into a pipe. CONSTITUTION: The optical fibers 3 are formed by coating the surfaces of optical fiber glass with primary coating layers of UV curing type resins or silicone resins. While six pieces of such fibers are placed longitudinally along the outer periphery of, for example, one fiber as a center, these fibers are bundled and thereafter, the fibers are twisted and doubled around the nearly straight cord 4 consisting of a fiber bundle of cotton, etc., or foamed plastic material and having the cushion property, by which the optical fiber unit 1 is formed. The optical fiber units 1 formed in such a manner are provided with the extra lengths and are housed into the plastic tube or the pipe 2, such as aluminum pipe.  Then, the diameter of the cords 4 is reduced and the twist radius of the optical fibers 3 around the cords 4 is reduced when, for example, an external stress is applied on the optical fiber units 1 via the pipe 2 and the units 1 are elongated. The elongation and distortion are thus relieved.

Title: Surface treated steel excellent in corrosion resistance and its surface treating method
Inventor: TSUJIKAWA SHIGEO
IPC: B32B15/18
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To increase the corrosion resistance of a steel by prescribing the componental compsns. of coating of upper and lower layers formed on the surface of a steel. SOLUTION: Iron oxide or the like is adhered to the surface of a steel, which is thereafter heated at 525 to 950 deg.C to form α-Fe2 O3 -contg. coating. In this case, the content of α-Fe2 O3 is regulated to 8 to 100wt.% in the coating solid content. Furthermore, coating contg. 12 to 100wt.% titanium oxide is formed thereon. It has been found that, in the case such coating having a double layer structure is irradiated with light, the corrosion resistance of the steel remarkably improves. Namely, in the case titanium oxide is irradiated with light, by its photochemical properties, the steel as the stock is formed into a cathode and the titanium oxide is formed into an anode, and it cathodically prevents the corrosion of the steel to improve its corrosion resistance. Since the titanium oxide is not consumed at all in the anodic reaction at this time and does not deteriorate, this effect is maintained semipermanently in the presence of light.
