摘要:
The present invention provides a method for producing a copolymer containing a perhaloolefin and vinyl acetate by a novel emulsion polymerization method. The present invention relates to a method for producing a perhaloolefin-vinyl acetate copolymer by emulsion polymerization of at least a perhaloolefin having two carbon atoms and vinyl acetate in the presence of a hydrocarbon emulsifier or in the absence of an emulsifier, provided that the hydrocarbon emulsifier excludes a compound (1) represented by the formula (1): wherein R1 and R2 are the same as or different from each other and each represent a C4 to 12 unfluorinated saturated hydrocarbon group; M represents an alkali metal, an ammonium salt, or an amine salt.

摘要:
In a brake control device and a brake control method, when a shift to a brake mode for backup involving separation of a supply path of working fluid is performed at the time of detection of an abnormality during braking, a differential pressure acting between an outlet opening and an inlet opening of an open-close valve which is provided between a hydraulic pressure source that is used during the backup brake mode and wheel cylinders and which needs to be opened during the backup brake mode is lessened prior to the separation of the supply path of working fluid so that the open-close valve is opened in accordance with a valve-opening command. Therefore, at the time of switch of the control mode, the confinement of wheel cylinder pressure is avoided.

A plasma display panel has a sealed part where peripheral portions of a front plate and a rear plate are sealed to each other with a sealing member. The sealed part includes bead which regulates any gap formed between the peripheral portions of the front plate and the rear plate. A dielectric layer is formed as far as location of the bead but an insulator layer is formed short of the location of the bead in the sealed part on the side of a direction where display electrodes extend. The insulator layer is formed as far as the location of the bead but the dielectric layer is formed short of the location of the bead in the sealed part on the side of a direction where data electrodes extend. The bead has a diameter larger than a thickness of the dielectric layer and a height of barrier ribs summed with each other and at most twice as large as the thickness of the dielectric layer and the height of the barrier ribs summed with each other.

摘要:
To improve a force by which a base holds an inner mirror, a base 4 keeping a base inner 6 for holding an inner mirror 2 is constituted by a first base 30 bonded to a front window 3 and a second base 40 clasped by the base inner 6; the second base 40 comprises a recessed mating part 43 where the first base 30 is fitted, and wider parts 41a, 41b abutting against side faces 33a, 33b of the first base 30 and extending outward from the side faces 33a, 33b of the first base 30; when the first base 30 is fitted into the mating part 43 of the second base 40, the mating width of the base 4 mating with the base inner 46 can be expanded by the width of the wider parts 41a, 41b of the second base 40, whereby the force by which the base 4 holds the inner mirror 2 can be improved even if the first base 30 is commoditized.
