    摘要: The method for molding a bead portion for a green tire includes a bead core supporting step for supporting the bead core through a carcass ply upon expanding a diameter of a bead core supporter including a seating surface for supporting a radially inner surface of the bead core. Since the bead core supporter comprises an outer piece outside of the seating surface in a tire axial direction that rises up towards outside in the radial direction with a clearance between the same and the bead core, that is larger than the thickness of the carcass ply, it is possible to flip a carcass outer region up, that is outside in the tire axial direction than a sandwiched region of the carcass ply, sandwiched and held between the seating surface and the bead core, and to deform the carcass outer region into an outer inclined piece that is inclined and extended towards radially outside without including any partially bent portions. It further includes a curving step of pressing the outer inclined piece inward in the tire axial direction by using a ply winding ring for curving the same towards the outside surface and the radially outer surface of the bead core, and a pressing step of pressing a tip end portion of the curved outer inclined piece towards the radially outer surface of the bead core by using a pressing roller.

    摘要: The present invention relates to time-of-flight mass spectrometers that use a pulser to provide an orthogonal acceleration to a continuous flow of a beam of ions so as to cause a packet of ions to flow out into an orthogonal direction and enter a detector. The invention makes the size of the emission outflow aperture of a pulser in the direction of the continuous flow of ions greater than the size of the aperture of the ion detector in the direction of the continuous flow of ions. In particular, the size of the ion emission aperture is at least twice as large as the size of the aperture of the detector.

    摘要: Process for producing acrylonitrile or methacrylonitrile from propane or isobutane by ammoxidation at a temperature in the range of from 380 to 500.degree. C. in a fluidized-bed reactor containing a catalyst composition preheated to a temperature of not lower than 300.degree. C. and lower than the ammoxidation reaction temperature, the catalyst composition comprising a carrier having supported thereon an oxide catalyst comprising a compound oxide of molybdenum, vanadium, niobium and at least one element selected from tellurium and antimony, wherein the ammoxidation of propane or isobutane is preceded by a specific temperature elevation operation in which the catalyst temperature in the reactor is elevated, while supplying into the fluidized-bed reactor a molecular oxygen-containing gas together with a combustible gas capable of combustion by reaction with the molecular oxygen in the presence of said catalyst composition, until the temperature of the catalyst composition reaches said ammoxidation reaction temperature. The process of the present invention is advantageous in that the temperature elevation of the catalyst can be performed without suffering a deterioration of the catalytic activity during the temperature elevation, thereby allowing the catalyst to fully exhibit its performance.

    摘要: An image forming apparatus for calculating a masking coefficient is provides, in which the masking coefficient is calculated by using RGB input image signals obtained by reading a document of which spectral characteristics are known by an image reading part and CMYK output image signals optimal for reproducing a color of the document. The masking coefficient can be also calculated by using difference values between CMYK output image signals obtained from actually read RGB signals and optimal CMYK output image signals.
