摘要:
A resin composition for an aqueous coating material that includes a propylene-butene resin component and/or propylene-ethylene-butene resin component (A), and a (meth)acrylic resin component (B), wherein the mass ratio between the propylene-butene resin component and/or propylene-ethylene-butene resin component (A) and the (meth)acrylic resin component (B) is within a range from 15:85 to 75:25. Also disclosed are a method for producing such a resin composition and an aqueous coating material. The present invention is able to provide a resin composition for an aqueous coating material that is useful as a binder within an aqueous coating material that uses no organic solvents or chlorine compounds, and yet exhibits excellent adhesion to polyolefin-based resins and is capable of forming a coating film that is resistant to discoloration and exhibits favorable resistance to the oils contained within gasoline, cosmetic products and foodstuffs and the like, and is also able to provide a method for producing the resin composition and an aqueous coating material that uses the resin composition.

An inorganic thin film EL device comprises, on an insulating substrate 1, a back electrode 2, an insulating layer 3, a light emission layer 4, an insulating layer 3, and a transparent electrode 5 formed on the substrate 1 in this order. The emission layer comprises a fluoride of an alkaline earth metal and at least one member selected from the group consisting of rare earth element metals and compounds thereof at a mixing ratio by weight of 10:90 to 95:5. The rare earth element is, for example, cerium, praseodymium, neodium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and mixture thereof. The compounds may be those compounds of the rare earth elements and fluorine, chlorine, bromine, iodine and oxygen.
摘要:
A hydraulic anti-lock brake system for a motor vehicle including a detector for obtaining rotating speeds of front right and left wheels and rear right and left wheels of the vehicle, hydraulic brakes for braking the front and rear wheels with brake pressures, and an anti-lock pressure regulating device for controlling the brake pressures on the basis of an output of the detector, so as to prevent excessive slipping of the front and rear wheels, the anti-lock pressure regulating device including a device for generating a pressure difference between the brake pressures for the rear right and left wheels, such that the brake pressure for the higher-speed rear wheel is lower than that for the lower-speed rear wheel, so that the higher-speed rear wheel is used as a speed monitoring wheel whose speed is used by the pressure regulating device for control the brake pressures.
