    摘要: This invention provides PVDF having such crystallization properties as to produce small spherulite sizes without sacrifices to properties, processability, purity, etc., and a suspension polymerization method to obtain the same.The PVDF obtained by this invention comprises the monomer unit content of 99.5-96 wt. % of vinylidene fluoride, and the monomer unit content of 0.5-4 wt. % of comonomers selected from hexafluoropropylene and/or tetrafluoroethylene, and has a logarithmic viscosity of 0.9-1.3 dl/g, and a molecular-weight distribution, as expressed in the ratio (Mw/Mn) of weight-average molecular weight and number-average molecular weight, of 2.2-2.8.In order to manufacture the PVDF of this invention, a mixture of vinylidene fluoride monomers containing 1-5 wt. % of monomers selected from hexafluoropropylene and/or tetrafluoroethylene is suspension-polymerized in an aqueous medium, using an oil-soluble initiator so that the logarithmic viscosity [.eta..sub.1 ] is kept at 1.3-1.9 dl/g until the polymerization conversion rate of vinylidene fluoride monomers becomes 10-50%, and the polymerization is continued by adding a chain transfer agent at that polymerization conversion rate so that the logarithmic viscosity [.eta..sub.2 ] of the eventually obtained polymers becomes 0.3-0.7 dl/g lower than [.eta..sub.1 ], and yet remains in the range of 0.9-1.3 dl/g.

    摘要: A vinylidene fluoride copolymer having a relatively high molecular weight is formed by copolymerizing (a) vinylidene fluoride as a principal component, (b) a small amount of epoxy group-containing monomer, and (c) an optional component, such as an unsaturated dibasic acid monoester functioning as a curing agent for the epoxy group. When cured with an optional epoxy curing agent, the vinylidene fluoride copolymer provides a cured product having an adhesion with a metal substrate, etc., and also showing excellent solvent resistance and chemical resistance. The vinylidene fluoride copolymer is particularly suitable for constituting a binder for producing an electrode for a non-aqueous solvent-type secondary battery.

    摘要: A second vertical heat treating apparatus is temperature-calibrated based on a heat treatment result obtained by a first vertical heat treating apparatus for reference. First, temperature measurement wafers is heated in the first apparatus to obtain set values of temperature controllers for a target value of temperature. Then, wafers are subjected to an oxidizing process in the first apparatus by using these set values to form an oxide film. The thickness of the oxide film is measured and recorded as a reference film thickness. Then, wafers are subjected to an oxidizing process in a second apparatus at temperatures near the target value to form an oxide film. The thickness of the oxide film is measured, and difference in thickness between the oxide film formed in the second apparatus and the reference film thickness is obtained. The oxidizing process in the second apparatus is repeated to obtain set values of temperature controllers for the second apparatus at the time when the difference in film thickness becomes zero. The second apparatus is temperature-calibrated on the basis of the set value thus obtained.

    摘要: A jet loom comprising a weft measuring roller for continuously drawing out a weft from a supply package, a weft storage unit for temporarily accumulating and storing the weft drawn out from the supply package by the weft measuring roller, a main nozzle for jetting air to insert the weft into the warp shed, and a driving unit for sinusoidally varying the rotating speed of the weft measuring roller. The weft stored in the weft storage unit runs in a free running period in a free running mode at a comparatively high running speed. After the stored weft has exhausted, the weft is supplied for insertion directly from the weft measuring roller, so that the weft runs in a constrained running mode at a running speed constrained by the surface speed of the weft measuring roller. When the running mode of the inserted weft changes from the free running mode to the constrained running mode, the driving unit drives the weft measuring roller so that the surface speed of the weft measuring roller is higher than a speed Vf defined by: Vf=Lo/tc, where Lo is the weft length of the loom and tc is a time necessary for one weaving cycle of the loom.
