Title: Rubber composition and molding made therefrom
Inventor: IMAEDA TOSHIAKI
IPC: C08L9/02
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To obtain a composition which can give moldings highly resistant to aliphatic hydrocarbon fuels such as gasoline and can give smoothly demoldable vulcanized members by mixing a hydrogenated acrylonitrile/ butadiene rubber, a peroxide-type vulcanizing agent and a silicone oil. SOLUTION: The silicone oil used may be any one of methylsilicone, dimethylsilicone, methylphenylsilicone and a modified silicone oil. It is added in an amount of desirably 0.2 to below 2.0 pts.wt. per 100 pts.wt. hydrogenated acrylonitrile/butadiene rubber. Rubber moldings obtained by vulcanizing the composition are particularly useful as rubber molded components used in storage tanks for aliphatic hydrocarbon fuels such as gasoline or lubricating oils or in transportation pipe systems. A vibration-proof rubber molding for a fuel tank has a rubber hardness of 45-60Hs. Which is attained by adjusting the amounts of vulcanizing agents and additives.

Title: Color selecting electrode of cathode-ray tube
Inventor: ISHIHARA MASAYUKI
IPC: H01J29/07
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To change the last slit width regardless of the tensile force distribution by arranging an adjusting hole in a prescribed part corresponding to a tape part of a support part, and adjusting a width of a slit positioned on the outermost end of a perforated part according to a position or the size of the adjusting hole. SOLUTION: Since an adjusting hole 1 is arranged in a support part 15 of a flat grille, tensile force applied in the vertical direction to the lengthwise direction of an aperture grille acts on both side 16 parts of the adjusting hole 1 so as to generate stress concentration. That is, the adjusting hole 1 formed in the support part 15 for supporting both ends of a tape part 2 changes the local stress distribution in the tape part 2 on the basis of the size and a position. Thus, deformation quantity of the tape part 2 can regulate a width of the last slit part 4. A required process is only to set a width (d) of the adjusting hole 1 to, for example, (3/7) w so as to become d<=w to a width (w) of the tape part 2.
