Title: Inflated radial tire and its manufacture
Inventor: SHIMADA TAKU
IPC: B29D30/48
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To effectively prevent direct contact of organic fiber cords with each other by setting coating rubber for burying adjacent gaps of the cords of monofilaments or multifilaments to a specific thickness, thereby ensuring a sufficiently high burst limiting internal pressure and performing a reduction in weight of a tire. SOLUTION: A thickness of coating rubber for burying adjacent gap of organic fiber cords 5 having high elasticity and high tensile force in a bead core of a product tire is set to 0.001 to less than 0.2mm. This thickness is obtained by measuring all thicknesses of the rubber for burying the gaps of the adjacent cords in vertical, lateral, and oblique directions irrespective of sectional positions in a lateral cross section of the core and obtaining a mean value of them. 0.001mm is required for the thickness of the rubber to effectively prevent mutual contacts of the cords 5. Its maximum thickness is preferably 0.2mm or less to reduce a tensile stress difference operating at the cords 5 disposed on inner and outer peripheral sides in a radial direction.

Abstract: PURPOSE:To separate and analyze a sample without spoiling the reproductivity of a column owing to injecting operation by transporting the sample and a solvent in a sandwich state to a T-shaped connection part and introducing the sample into a capillary while varying the flow velocity of the solvent. CONSTITUTION:The mixed liquid of buffer liquid and micell is flowed from a container 2 to piping 8, the solvent is introduced at the T-shaped connection part into the capillary 1 whose tip is inserted into a tubular electrode 9, and the remainder is discharged from a tube 11. A constant amount of the sample is injected from the injection port S3 of a sample valve S and moves while sandwiched B in the sample, and the band B is introduced into the capillary 1 by an electroendosmose flow. When a voltage E is constant, the amount of the sample is proportional to the time when the sample contacts the capillary 1, so the flow velocity of a pump 7 is varied to adjust the contacting time.
